    Controls on dune scarping (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-21
    Description: The controls that affect the degree of spatio-temporal change to foredunes following scarping are reviewed herein. As sea-levels rises and climate changes, dune scarping will become more common. Thus, it is critical to understand what factors contribute to the magnitude of scarping, and what effect this has on dune systems to better manage coastal erosion into the future. Scarping occurs when foredunes are partially eroded by waves, generally during periods of high water level. The controls on the degree and magnitude of scarping examined include water level, foredune vegetation cover and species present, plant root mass, height and volume of the foredune, the original foredune morphology, surfzone–beach type, and compaction of sediment. Water-level height and duration of high water is the most significant control as it determines the elevation at which wave action can erode the dune and, therefore, the extent of scarping and dune volumetric loss. Higher plant density, greater rooting depth, high root mass, and greater compaction aid in reducing the degree of scaping. The presence of large woody debris and wrack may also influence the degree of scarping. The effects scarping has on the morphology of a foredune after the initial erosion event can range from small changes (e.g. minor, small scarps and slight slumping), to moderate changes such as the foredune translating landwards, to large change such as the transition of an entire dune system into a new transgressive dunefield phase. A new model summarising the key controls and their relationship/significance to the magnitude and extent of scarping is presented.

    Animal geographies II: Killing and caring (in times of crisis) (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-21
    Description: Humans kill and care for animals in a multitude of contexts. These themes – killing and caring – form the focus of this second report on animal geographies research. Most notably, killing and caring take place through conservation and the production and consumption of food. Other realms of recent research include killing through climate change, formal arrangements of care, how animals are made killable, and the significance of the individual and collective. Further to these two major themes, the review identifies other approaches to animal geographies research in recent years; namely, political and relational. Finally, the propensity for humans to kill and care for animals is highlighted by crisis. I open and close the review by considering connections between animals and two contemporary emergencies: the fires that burned south-eastern Australia over summer 2019–20 and the COVID-19 pandemic.

    Professions and their expertise: Charting the spaces of ‘elite’ occupations (2020)
    Sage Publications
    Details
    Publication Date: 2020-08-31
    Description: This paper argues for a sustained study of knowledge-intensive or liberal professions in geography. I review existing work in political geography and related fields to identify a gap in the study of knowledge-intensive professions, especially those that are popularly associated with elites. I draw from sociology, anthropology, and international relations to explain why we need to better understand such professions. By the geographical study of professions and their expertise I mean the examination of the places, spatial networks, and travels of ideas that shape these professions and the expertise created therein.

    Inner Asian agro-pastoralism as optimal adaptation strategy of Wupu inhabitants (3000–2400 cal BP) in Xinjiang, China (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-16
    Description: Exploring ancient socio-economic adaptation is a basic issue of human-environment interaction. Xinjiang in northwest China is a region of high geographic diversity. Past human adaptations to this arid marginal area is a current focus of research interest but still lacks in-depth study. This article presents data from the Wupu Cemetery, located in the extremely arid Hami Basin in the eastern Tianshan Mountains. Archaeobotanical analysis is used to reconstruct the local environment niche and the subsistence economy of inhabitants. Radiocarbon dating results indicate the cemetery was occupied between 3000 and 2400 cal BP, during the late Bronze Age and early Iron Age. In total 16 species of the plant remains are identified, including four cereal crops, foxtail millet ( Setaria italica), broomcorn millet ( Panicum miliaceum), naked barley ( Hordeum vulgare var. coeleste), wheat ( Triticum aestivum) and 12 wild types. The riparian plant Populus euphratica and aquatic plant Typha sp. indicate inhabitants lived in an oasis near the cemetery. Environmental interpretation of this data compares well with other seven sites in arid southern Xinjiang. In addition to faunal remains from the site, it is assumed that a flexible system of multi-crop farming and herding was the subsistence pattern around Wupu. This system was widespread across Inner Asia and appears to have played a central role in adapting to different marginal environments during the Bronze Age and Iron Age.

    The impact of early trans-Eurasian exchange on animal utilization in northern China during 5000–2500 BP (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-15
    Description: Transcontinental exchange emerged and intensified in northern China since the late fifth millennium BP (Before present), especially in the arc, which was the core area of the eastern part of the trans-Eurasian exchange during the Late Neolithic and the Bronze Age. In the arc, the exchange profoundly affected the human subsistence strategy and human-environment relationship. Relative to the crop patterns and human diets during the Bronze Age in northern China, systematic investigations of zooarcheological data based on broad spatial and temporal framework to understand the influence of introduced livestock and indigenous livestock on human subsistence are lacking. To show the spatial-temporal variation in animal utilization patterns and its relation to prehistoric trans-Eurasian exchange, the zooarcheological data from 40 sites in northern China dated between 5000 and 2500 BP were analyzed. The strategy of animal utilization in northern China changed substantially from 5000 to 2500 BP, with notable spatial features in different chronological phases. From 5000 to 4300 BP, wild mammals and indigenous livestock (pig, dog) use dominated in the arc and the North China Plain (NCP). During 4300–3500 BP, the importance of introduced livestock (cattle, sheep/goat, horse) exceeded that of indigenous livestock in the arc, whereas indigenous livestock continued to dominate in the NCP. Indigenous livestock acted as the most important animal subsistence in northern China, although the exploitation of introduced livestock increased during 3500–2000 BP. These spatio-temporal differences in animal utilization appear to be closely associated with the prehistoric trans-Eurasian exchange, but were also affected by local environment, agriculture development, and climate change.

    Are there enormous age-trends in stable carbon isotope ratios of oak tree rings? (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-15
    Description: We test a recent prediction that stable carbon isotope ratios from UK oaks will display age-trends of more than 4‰ per century by measuring 〉5400 carbon isotope ratios from the late-wood alpha-cellulose of individual rings from 18 modern oak trees and 50 building timbers spanning the 9th–21st centuries. After a very short (c.5 years) juvenile phase with slightly elevated values, the number of series that show rising and falling trends is almost equal (33:35) and the average trend is almost zero. These results are based upon measuring and averaging the trends in individual time-series; the ‘mean of the slopes’ approach. We demonstrate that the more conventional ‘slope of the mean’ approach can produce strong but spurious ‘age-trends’ even when the constituent series are flat, with zero slope and zero variance. We conclude that it is safe to compile stable carbon isotope chronologies from UK oaks without de-trending. The isotope chronologies produced in this way are not subject to the ‘segment length curse’, which applies to growth measurements, such as ring width or density, and have the potential to retain very long-term climate signals.

    Fire, humans and climate as drivers of environmental change on Broughton Island, New South Wales, Australia (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-10
    Description: In Australia, the drivers of precolonial fire regimes remain contentious, with some advocating an anthropogenic-dominated regime, and others highlighting the importance of climate, climatic variability or alternatively some nexus between climate and human activity. Here, we explore the inter-relationships between fire, humans and vegetation using macroscopic charcoal, archaeology and palynology over the last ~5430 cal. year BP from Broughton Island, a small, near-shore island located in eastern Australia. We find a clear link between fire and the reduction of arboreal pollen and rainforest indicators on the island, especially at ~4.0 ka and in the last ~1000 years. Similarities with comparable palaeoenvironmental records of fire in the region and a record of strong El Niño (dry, fire-prone) events supports the contention that climate was a significant influence on the fire regimes of Broughton Island. However, two periods of enhanced fire activity, at ~4000 years BP and ~

    Vegetation response to wildfire and climate forcing in a Rocky Mountain lodgepole pine forest over the past 2500 years (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-10
    Description: Wildfire is a ubiquitous disturbance agent in subalpine forests in western North America. Lodgepole pine ( Pinus contorta var. latifolia), a dominant tree species in these forests, is largely resilient to high-severity fires, but this resilience may be compromised under future scenarios of altered climate and fire activity. We investigated fire occurrence and post-fire vegetation change in a lodgepole pine forest over the past 2500 years to understand ecosystem responses to variability in wildfire and climate. We reconstructed vegetation composition from pollen preserved in a sediment core from Chickaree Lake, Colorado, USA (1.5-ha lake), in Rocky Mountain National Park, and compared vegetation change to an existing fire history record. Pollen samples ( n = 52) were analyzed to characterize millennial-scale and short-term (decadal-scale) changes in vegetation associated with multiple high-severity fire events. Pollen assemblages were dominated by Pinus throughout the record, reflecting the persistence of lodgepole pine. Wildfires resulted in significant declines in Pinus pollen percentages, but pollen assemblages returned to pre-fire conditions after 18 fire events, within c.75 years. The primary broad-scale change was an increase in Picea, Artemisia, Rosaceae, and Arceuthobium pollen types, around 1155 calibrated years before present. The timing of this change is coincident with changes in regional pollen records, and a shift toward wetter winter conditions identified from regional paleoclimate records. Our results indicate the overall stability of vegetation in Rocky Mountain lodgepole pine forests during climate changes and repeated high-severity fires. Contemporary deviations from this pattern of resilience could indicate future recovery challenges in these ecosystems.

    Scopic relations as spatial relations (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-08
    Description: The aim of this paper is to elucidate the dynamic interplay of visuality, space and power through an analysis of what we call scopic relational spaces (SRS). Our primary claim is that scopic relations are intrinsically spatial relations and scopic practices are spatial practices. We contend that such analysis facilitates the discernment of significant socio-spatial processes and events that are otherwise unrecognized. We suggest that attention to the socio-spatial phenomena under investigation can contribute to debates about the alleged incommensurability of territorial and relational spatial imaginaries.

    Impact of bedrock geochemistry on vegetation productivity depends on climate dryness in the Guizhou karst of China (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-08
    Description: The Guizhou karst area is one of the largest continuous areas of karst in the humid climate zone and is representative of karst landforms in China. Large portions of the karst system are characterized by extremely shallow soils underlain by weathered bedrock and water deficits are common. Although the distribution of ecosystem productivity is largely related to variations in the temperature and precipitation, the influence of the substrate in karst areas requires further exploration. We explored the relative importance of the bedrock geochemistry (characterized by the concentrations of Ca, Mg and Si) and climatic factors (temperature and precipitation) to explain the spatial variability in gross primary productivity (GPP) with various degrees of water deficit during the time period 2001–2015. Our results show that the impact of bedrock geochemistry is an important parameter in changing the original relationship between climate and the GPP. The bedrock geochemistry functioned as a “regulator” of the relation between climate and the GPP, which strengthened with decreasing climate favourability. The variations in GPP and surface water storage were significantly different when different elements (Ca, Mg or Si) were dominant. The Mg-rich regions showed the greatest annual variations in the GPP, whereas the Si-rich regions had the strongest surface water storage potential to support vegetation growth. The results of our study are important for systematically evaluating the effects of climate on vegetation productivity and provide a benchmark for global vegetation modelling predictions.

    Publication Date: 2020-07-08
    Description: In this paper, we identify the ways in which the existing literature has examined financial technology (FinTech). Using the frame of the ‘FinTech Cube’, we examine how FinTech unfolds through the intersections of key actors, technologies and institutions. We demonstrate the relevance of FinTech for two areas of geographical enquiry: i) the reshaping of global production and financial networks, and ii) financial inclusion and poverty reduction in poorer countries. In doing so, we accord particular attention to the significance of FinTech for theoretical and empirical research in economic geography.

    Climate and social change at the start of the Late Antique Little Ice Age (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-09
    Description: The Late Antique Little Ice Age, spanning the period from 536 CE to roughly 560 CE, saw temperatures in the Northern Hemisphere drop by a degree C in less than a decade. This rapid cooling is thought to have caused widespread famine, epidemic disease, and social disruption. The relationship between cooling and social disruption is examined here using a set of high-resolution climate and historical data. A significant link between cooling and social disruption is demonstrated, but it is also demonstrated that the link is highly variable, with some societies experiencing dramatic cooling changing very little, and others experiencing only slight cooling changing dramatically. This points to variation in vulnerability, and serves to establish the Late Antique Little Ice Age as a context within which naturalistic quasi-experiments on vulnerability to climate change might be conducted.

    Bodies and persons: The politics of embodied encounters in asylum seeking (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-02
    Description: In this paper, we propose that there is a politics of encounters centered on the body at play in seeking asylum and refuge, and that it is critical to study how it unfolds from the point of view of both governing and agency. Building on existing work that looks at the role of embodiment in the political struggles of refugees, and leaning on Helmuth Plessner’s original thinking about social embodiment, we develop a theoretical understanding of this political dynamic, illustrating how it can help us make sense of power relations and forms of governance and (latent) resistance involved in it.

    GIScience I: Social histories and disciplinary crucibles (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-02
    Description: In this first report, I overview research on storytelling of the histories of GIS. I suggest that these efforts reveal important pathways for thinking the current moment and conditioning technoscience futures. I argue that these stories around technology illustrate various disciplinary crucibles around technical practices and knowledge work. To report on progress in GIScience is also to narrate the moments of change in the discipline, whether marked as quantitative, qualitative, radical, critical, black, feminist, Marxist, indigenous, environmental, postcolonial, queer, or minor, among others. I suggest ‘minor GISciences’ to encourage attentiveness to the historical conditions and social implications of geographic technologies.

    Territory and territorial stigmatisation: On the production, consequences and contestation of spatial disrepute (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-02
    Description: Territorial stigmatisation emerged over the past decade as the prevailing concept for understanding the phenomenon of disreputable places and the processes by which they are produced. Following the work of Loïc Wacquant, several studies have articulated its centrality to the neoliberal restructuring of capital and the state. Departing from Wacquant, several have also examined the various forms of resistance to territorial stigmatisation. In reviewing this literature, this paper argues and outlines how territory – paradoxically under-theorised in the literature to date – can clarify the production of territorial stigmatisation, the obfuscations and legitimations it performs, and resistance and contestation.

    New geographies of commemoration (2020)
    Sage Publications
    Details
    Publication Date: 2020-07-02
    Description: This article identifies new geographies of commemoration. These draw on non-representational perspectives that foreground the experiential aspects of commemorative sites and events, drawing these together with methodologies alive to the subtle but excessive feelings that arise in such settings. It argues that one aim of commemoration – to reinforce the contours of national identity – is disrupted by a focus on the experiential world because of the unpredictable and excessive nature of sensory and affective feelings. New research in geographies of commemoration also draws together different temporalities, holding the potential to unsettle and complicate national narratives.

    Quaternary environmental change in New Zealand: a review (1999)
    Sage Publications
    Details
    Publication Date: 1999-12-01
    Description: The discovery that orbital variations are the driving force behind Quaternary climate change provides an impetus to set local and regional records of environmental change into the global context, a principle that has been strongly embraced by Quaternary scientists working in New Zealand. Their major achievements and significant current initiatives are reviewed here. The importance of the New Zealand Quaternary stems from its geographical context: a climatically sensitive, remote oceanic, southern location spanning 17 degrees of the mid-latitudes; an obliquely convergent plate boundary setting resulting in a high mountain range athwart the prevailing westerlies, active volcanism, a youthful and dynamic landscape, and mountains high enough to maintain glaciers today; and a remarkably short prehistory. The resultant records show marked environmental changes due not only to climatic oscillations but also to vigorous, active tectonism and volcanism. The Taupo Volcanic Zone, containing the world's strongest concentration of youthful rhyolitic volcanoes, has produced at least 10 000 km3of magma in the last 2 Ma. Climatic interpretations of records from marine sediments in the New Zealand region, together with several long sequences of alternating marine and terrestrial sediments, indicate broad synchrony with Northern Hemisphere events (within limitations of dating), although there are differences in detail for shorter-term climatic events. It is not yet certain that glacial advances coincided precisely with those in the Northern Hemisphere or were of similar duration. Late Cainozoic glaciation commenced c. 2.6-2.4 Ma but the record of glacial deposits is fragmentary and poorly dated except for the most recent events. The Last (Otira) Glaciation, from c. 100-10 ka, was characterized by at least five glacial advances including during the Last Glacial Maximum from 25 to 15 ka, when snowlines fell by 600-800 m. New Zealand evidence for cooling during the Younger Dryas stade is equivocal whilst isotopic records from speleothems, and other data, indicate warmer and wetter conditions from 10-7 ka, broadly conforming with records from mid-latitude Northern Hemisphere locations. Future advances will require sampling at shorter timescales, improvements in the accuracy and precision of existing dating methods and the development of new ones, extension of palaeoecological techniques to cover the full potential of new Zealand's diverse biota, and a stronger emphasis on quantification of palaeoclimatic parameters.

    The 1755 Lisbon earthquake (2001)

    Details
    Publication Date: 2001-09-01
    Description: Affecting an area of ca. 800 000 km2and killing up to 100 000 people, the Lisbon earthquake of 1755 is probably the greatest seismic disaster to have struck western Europe. The shock waves of the earthquake placed a temporary brake on the emerging rationalism of the European Enlightenment and attempts to explain the disaster in terms of human sinfulness coloured many contemporary accounts. Notwithstanding these difficulties, through careful archival research it has proved possible to obtain relatively value-free accounts of most aspects of the earthquake and to use these not only to model the physical characteristics of and damage caused by the earthquake, but also to consider the implications for present day hazard assessment and urban planning. This paper reviews the progress that has been made in: identifying source and faulting mechanisms; the processes involved in the generation and impact of tsunamis; damage caused to different types of building and the use being made of historical earthquakes of different sizes - of which the 1755 event is the largest - in defining future hazard scenarios for Lisbon and other areas of Iberia.

    The palaeogeography of Mesolithic settlement-subsistence and shell midden formation in the Muge valley, Lower Tagus Basin, Portugal (2007)
    Sage Publications
    Details
    Publication Date: 2007-04-01
    Description: This paper reports the first detailed palaeogeographical analysis of the environmental context of late Mesolithic shell midden sites in the lower Tagus area and focuses on the lower Muge valley, which contains an internationally significant Mesolithic record. The lower Muge valley fill comprises buried estuarine and fluvial environments contemporary with Mesolithic settlement. Holocene environmental and palaeogeographic changes influenced Mesolithic settlement-subsistence and midden accumulation. The sudden appearance of large late Mesolithic shell middens throughout Portugal represents a process of increased visibility and preferential preservation of the archaeological record. Prior to ~6100 cal. BC, aggrading valley floor environments did not occupy the entire width of the present lower Tagus floodplain and any sites located in the early Holocene valley are currently deeply buried. Shell midden occupation on terrace levels followed the establishment of aggrading estuarine environments, containing productive shell beds, near the mouth of the lower Muge valley at ~6100 cal. BC. The critical factors in site choice appear to have been the nearby presence of (i) rich shell resources and (ii) freshwater environments. Long-term site occupation and (semi-)sedentary behaviour was favoured by the local presence, for over 2000 years, of rich resources from estuarine, freshwater and open woodland environments. Site abandonment (~5300—4800 cal. BC) coincided with the regional establishment of an open landscape (~5000 cal. BC) and the contraction of local estuarine environments (~5555—3800 cal. BC). The associated gradual decrease in resources and cultural interaction with the expanding early Neolithic communities may have influenced Mesolithic site abandonment.

    Pollen productivity estimates for quantitative reconstruction of vegetation cover on the Swiss Plateau (2007)
    Sage Publications
    Details
    Publication Date: 2007-01-01
    Description: We present the first step to quantitatively reconstruct vegetation cover in central Europe. Modern vegetation and pollen deposition were compared for 20 small to medium sized lakes and their catchments on the Swiss Plateau, a relatively flat region between the Jura Mountains and the Alps. To correct for the pollen dispersal bias in pollen assemblages, vegetation abundance was distance-weighted using three different approaches. The Relevant Source Area of Pollen (RSAP) and pollen productivity of 13 plant taxa were estimated using three different submodels of the Extended R-Value model (ERV-model). RSAP was 800 m regardless of the applied distance-weighting or ERV submodel. Pollen Productivity Estimates (PPE) varied from 10 to 〈 0.1 among pollen taxa and differed slightly between the models. Relative to grasses most trees were higher pollen producers and some were equal producers, whereas the herb taxa showed lower PPE. Generally, PPE from lowland Switzerland differ from those found in other European regions. Sampling strategies of vegetation and pollen samples are a likely cause for this variation. However, pollen productivity is also influenced by regionally different factors, such as climate, vegetation structure, geology and soil types. In addition, differences at genus or species level may occur between areas. Our comparison between the different regions in Europe shows that PPE of one region may not be directly applicable to other regions.

    Wetlands in drylands: geomorphological and sedimentological characteristics, with emphasis on examples from southern Africa (2007)
    Sage Publications
    Details
    Publication Date: 2007-02-01
    Description: Wetlands are poorly documented features of many landscapes, and there is often little understanding of the geomorphological controls on their origin, development and characteristics. This paper addresses the apparent paradox of wetlands in drylands, focusing particularly on the geomorphology and sedimentology of wetlands in southern Africa. Drylands are characterized by high (but variable) levels of aridity, reflecting low ratios between precipitation and potential evapotranspiration, so wetlands can only exist where there are locally positive surface water balances for all or part of the year. Most moderate to large wetlands in drylands are thus maintained by river inflows that combine with other factors that serve to impede drainage or reduce infiltration, including faulting, rock outcrops, swelling soils, and ponding by tributary or aeolian sediments. Together with variations in sediment supply, vegetation communities, and levels of animal activity, this promotes a diverse range of wetlands that span a continuum from permanently inundated, to seasonally inundated, to ephemerally inundated. In detail, every wetland has a unique range of geomorphological and sedimentological characteristics but, at a general level, the dryland setting can be shown to impart some distinctive features. By comparison with humid region (tropical and temperate) wetlands, we propose that many wetlands in drylands are characterized by: 1) more frequent and/or longer periods of desiccation; 2) channels that commonly decrease in size and even disappear downstream; 3) higher levels of chemical sedimentation; 4) more frequent fires that reduce the potential for thick organic accumulations and promote aeolian activity; and 5) longer timescales of development that may extend far back into the Pleistocene. Additional studies of wetlands in different drylands may reveal other distinctive characteristics. Correct identification of the factors giving rise to wetlands, and improved understanding of the geomorphological and sedimentological processes governing their development, is vital for the design of sustainable management guidelines for these diverse yet fragile habitats.

    Research on glaciers and snow in New Zealand (1999)
    Sage Publications
    Details
    Publication Date: 1999-12-01
    Description: The glaciers and snowfields of the Southern Alps of New Zealand are the most significant in the Southern Hemisphere outside Antarctica and South America. The most substantial data on Southern Hemisphere glacier fluctuations come from New Zealand. The nature and behaviour of New Zealand's glaciers are also of wider scientific interest, because they are highly sensitive, high input-output systems that represent the temperate, maritime end of the glacier process-behaviour continuum. The areal extent and volume of glaciers and snow are outlined and an assessment is made of their scientific relevance and of their importance as resources and hazards. The main themes and progress of research on glaciers and snow, including snow avalanches, are reviewed. Glacier research has concentrated on only a few key glaciers and has focused on understanding glacier change. Main topics covered in this review relate to this focus and include fluctuations in termini, other mass balance signals and response to climate variability. Research on mass balance processes, glacier dynamics and glacier hydrology is also outlined. Seasonal snow has received less attention until recently. The main emphasis has been on quantification and past variability and its contribution to river flow, particularly in the most important hydroelectric power catchments of the South Island. Some field measurements have been made of the energy balance over snow. Research on snow avalanches has grown as the demands of winter recreation and alpine tourism have increased the hazard. Research first concentrated on production of avalanche atlases for the most hazardous areas and on quantifying the nature of the hazard. Subsequently, there has been a shift towards more process studies that are related to avalanche formation and runout distance. The main gaps in research on glaciers and snow are identified and key areas for future work proposed. There is an urgent need, in particular, for glacier mass-balance measurements. Extensive data on snow structure need to be synthesized. Satellite imagery should be used for monitoring of seasonal snow. Snow melt during northwest storms needs to be better defined. A more developed engineering approach is required for the study of snow avalanches. New Zealand offers exciting possibilities for the study of cryospheric processes, including response to future climate change.

    Satellite remote sensing of natural Mediterranean vegetation: a review within an ecological context (2000)
    Sage Publications
    Details
    Publication Date: 2000-06-01
    Description: Mediterrranean regions are characterized by high spatiotemporal heterogeneity of vegetation patterns. Understanding the dynamic nature of these environments requires detailed data for wide regions regarding changes in their phyto-ecology, biomass and productivity. This article assesses the current status of satellite remote sensing in this field of application. Mapping the five main life-forms (physiognomic classes) in Mediterranean regions (forests, woodlands, scrub, dwarf shrubs and herbaceous growth) has attracted major attention in recent years. Methodologies developed for this purpose are based on the spectral, temporal and spatial (textural) information domains provided by satellite data. Wide regional vegetation mapping was achieved using phenological classification of vegetation indices derived mainly from NOAA AVHRR images. More detailed mapping was conducted with multispectral techniques in local areas using mainly Landsat TM images. Assessments of multispectral and multi-temporal categories have shown limitations in their applicability over wide regions due mainly to the heterogeneity of Mediterranean regions. This heterogeneity cannot be regarded as a simple mixing of life-forms over large areas but, rather, the formation of transitional zones of varying mixtures resulting from disturbance and recovery cycles. Productivity and biomass monitoring has been found to be an active methodological development due to the introduction of new off-nadir viewing sensors in the visible and infrared spectral bands, and because of the development of methodologies for the retrieval of biophysical information from Synthetic Aperature Radar (SAR) data. Studies of ecosystem evolution using satellite data were conducted mainly in the fields of fire disturbance and desertification. Further progress in the remote sensing of Mediterranean vegetation ecology requires a better synergy of sensors, methods and ancillary data.

    Palynological evidence for environmental and climatic change in the lower Guadiana valley, Portugal, during the last 13 000 years (2007)
    Sage Publications
    Details
    Publication Date: 2007-05-01
    Description: Pollen analysis of a 48 m AMS radiocarbon-dated sediment sequence from the Guadiana estuary provides the first record of Lateglacial and Holocene vegetation history in the Algarve province of Portugal. This paper focuses on the record of terrestrial pollen taxa, which document a series of forest expansions and declines during the period 13 000 cal. BP to 1600 cal. BP and provide insights into climate evolution in southwestern Iberia. The main vegetation phases identified in the Guadiana valley are (1) Lateglacial interstadial (Allerød) forest with Quercus and Pinus under a temperate, moist, continental climate; (2) a Younger Dryas forest decline ( Quercus) and expansion of pinewoods, xeric scrub and open ground habitats (with Juniperus , Artemisia, Ephedra distachya type, Centaurea scabiosa type) under arid and cold conditions; (3) an early Holocene forest/scrub/open-ground vegetation mosaic developing under a warm, dry and continental climate; (4) a maximum of Quercus forest and thermomediterranean evergreen taxa ( Olea, Phillyrea, Pistacia) reflecting a warm, moist oceanic climate between c. 9000 cal. BP and c. 5000 cal. BP; and (5) the expansion of shrublands with Cistaceae and Ericaceae under a drier climatic regime and increasing anthropogenic activity since c. 5000 cal. BP. Holocene episodes of maximum climatic aridity are identified in the record of xerophytic taxa ( Juniperus, Artemisia, Ephedra distachya type) centred around 10 200 cal. BP, 7800 cal. BP, 4800 cal. BP, 3100 cal. BP and 1700 cal. BP. Regional comparisons suggest a correlation of arid phases across southern Iberia and northwest Africa, which can be related to abrupt North Atlantic coolings (Bond events).

    Hydrography and climate of the last 4400 years in a SW Greenland fjord: implications for Labrador Sea palaeoceanography (2007)
    Sage Publications
    Details
    Publication Date: 2007-04-01
    Description: A multiproxy record including benthic foraminifera, diatoms and XRF data of a marine sediment core from a SW Greenland fjord provides a detailed reconstruction of the oceanographic and climatic variations of the region during the last 4400 cal. years. The lower part of our record represents the final termination of the Holocene Thermal Maximum. After the onset of the `Neoglaciation' at approximately 3.2 ka cal. BP, the fjord system was subject to a number of marked hydrographical changes that were closely linked to the general climatic and oceanographic development of the Labrador Sea and the North Atlantic region. Our data show that increased advection of Atlantic water (Irminger Sea Water) from the West Greenland Current into the Labrador Sea was a typical feature of Northeast Atlantic cooling episodes such as the `Little Ice Age' and the `European Dark Ages', while the advection of Irminger Sea Water decreased significantly during warm episodes such as the `Mediaeval Warm Period' and the `Roman Warm Period'. Whereas the `Mediaeval Warm Period' was characterized by relatively cool climate as suggested by low meltwater production, the preceding `Dark Ages' display higher meltwater runoff and consequently warmer climate. When compared with European climate, these regional climate anomalies indicate persisting patterns of advection of colder, respectively warmer air masses in the study region during these periods and thus a long-term seesaw climate pattern between West Greenland and Europe.

    Palaeofluvial geomorphology in southern Africa: a review (1998)
    Sage Publications
    Details
    Publication Date: 1998-09-01
    Description: This article presents an overview of palaeofluvial geomorphology research in southern Africa. For the purposes of this article this includes South Africa, Zimbabwe, Namibia, Lesotho, Swaziland and Botswana. Although interest in fluvial systems has a long history in southern Africa, the scientific study of rivers was initiated by the discovery of the first alluvial diamond along the banks of the Orange River in 1867. Since then, significant progress has been made in unravelling the fluvial history of southern Africa from the early Archaean Ventersdorp Contact Reef River to modern channel process studies. The development of an understanding of palaeofluvial systems has occurred along two main lines. The first was alluvial diamond exploration work undertaken by the large mining houses. The second line was of a more ‘academic’ interest and included determining the impact of superimposition, tectonics, base level and climate changes. The review suggests that southern Africa fluvial systems have shown large-scale changes in drainage pattern, discharge and sediment yield and that these can be related to a complex set of causative factors including the geological template, the Jurassic rifting of Gondwana, tectonic episodes and climate change.

    Patterns and processes of sediment sorting in gravel-bed rivers (1998)
    Sage Publications
    Details
    Publication Date: 1998-03-01
    Description: Sedimentological studies of coarse-grained alluvial rivers reveal patterns of bed material sorting at a variety of spatial scales ranging from downstream fining over the length of the long profile to the vertical segregation of a coarse surface layer at the scale of individual particles. This article reviews the mechanisms that sort bed material by size during sediment entrainment, transport and deposition and discusses some of the inter-relationships that exist between patterns and processes of sediment sorting at different spatial and temporal scales. At initiation of motion, sorting can arise from the preferential entrainment of the finer fractions from the heterogeneous bed sediments. Bedload grain-size distributions are modified during transport as different size fractions are routed along different transport pathways under the influence of nonuniform bed topography and associated flow patterns, and during deposition as the variable pocket geometry of the rough bed surface and turbulence intensity of the flow control the size of the particles that deposit. The review highlights the poor understanding of the many feedback linkages that exist between patterns and processes of sediment sorting at different scales and the need for a greater awareness of the spatial and temporal bounds of these linkages.

    Impacts of mass movement erosion on land productivity: a review (2000)
    Sage Publications
    Details
    Publication Date: 2000-03-01
    Description: Wherever people gain their livelihood in mountains and steeplands, the productive capacity of the soils they use is likely to be affected by mass movement erosion. The impacts of mass movement erosion on land productivity are significant but under-rated in the scientific literature. Impacts on cropping are here reported from 15 countries in south and southeast Asia, east Africa, the Caribbean and Melanesia, but accounts are generalized or anecdotal, and do not quantify crop loss or damage attributable to mass movement separately from that due to surface or fluvial erosion. Impacts on pastoral grazing have been studied in New Zealand, where production losses of up to 80% at field scale, and up to 20% at farm scale, have been measured. Studies in the Pacific Northwest coastal forests of North America show plantation forest wood volume declines by 35-50% on eroded sites. Mass movement impacts on production from tropical forests or agroforestry appear to be as yet undocumented.The reasons for lack of documentation are, first, that most soil erosion-productivity research has been done on gently sloping cropland, which is subject to surface rather than mass movement erosion. Secondly, geomorphological research in steeplands has dealt with mass movement as a hazard to human life, settlements and infrastructure -with limited identification of its contribution to sediment loads in rivers, and disregarding its impact on land productivity.We suggest there are many other countries where significant impacts are likely to occur, and that erosion-productivity studies should pay more attention to this type of erosion. Studies should not be restricted to cropland, but also extend to grazing land, plantation forestry, agro-forestry and traditional uses of natural forest as mass movement appears to affect all these forms of land-based production, particularly in densely populated steeplands whether tropical or temperate. Topics needing study are the documentation and costing of productivity losses, ways to reduce mass movement impacts on productivity, and ways to enhance recovery of soil on eroded areas (e.g., revegetation with fertility-building shrubs and legumes).

    Infiltration into soils, with particular reference to its visualization and measurement by magnetic resonance imaging (MRI) (1998)
    Sage Publications
    Details
    Publication Date: 1998-06-01
    Description: This article draws attention to the potential of magnetic resonance imaging (MRI) for studies of patterns and mechanisms of water infiltration into soils, and stresses the vitally important need for collaboration between hydrologists, soil physicists and MRI experts. A brief introduction of the principles of MRI is given. This is followed by a review of the literature relating to nonpreferential infiltration, preferential infiltration exhibiting fingering and preferential infiltration involving a wide range of macropore flow. These differing degrees of complexity of infiltration dynamics require the employment of noninvasive and nondestructive techniques for their detailed investigation. Finally, an overview of applications of MRI to the detection of the spatial and temporal distribution of soil moisture and its changes is given. General conclusions are drawn from previous and current research, and the potential of the application of MRI to infiltration studies is summarized.

    HRSC-A data: a new high-resolution data set with multipurpose applications in physical geography (2007)
    Sage Publications
    Details
    Publication Date: 2007-04-01
    Description: The analysis and interpretation of remote sensing data facilitates investigation of land surface complexity on large spatial scales. We introduce here a geometrically high-resolution data set provided by the airborne High Resolution Stereo Camera (HRSC-A). The sensor records digital multispectral and panchromatic stereo bands from which a very high-resolution ground elevation model can be produced. After introducing the basic principles of the HRSC technique and data, applications of HRSC data within the multidisciplinary Research Training Group 437 are presented. Applications include geomorphologic mapping, geomorphometric analysis, mapping of surficial grain-size distribution, rock glacier kinematic analysis, vegetation monitoring and three-dimensional landform visualization. A final evaluation of the HRSC data based on three years of multipurpose usage concludes this presentation. A combination of image and elevation data opens up various possibilities for visualization and three-dimensional analysis of the land surface, especially in geomorphology. Additionally, the multispectral imagery of the HRSC data has potential for land cover mapping and vegetation monitoring. We consider HRSC data a valuable source of high-resolution terrain information with high applicability in physical geography and earth system science.

    Dating of the Narssarssuaq stade in southern Greenland (2007)
    Sage Publications
    Details
    Publication Date: 2007-02-01
    Description: Following the Holocene thermal maximum, the Greenland ice sheet began to expand, and many local glaciers formed. The maximum extent of most outlet glaciers from the Inland Ice was reached around 100 to 200 years ago. However, some exceptions have been recorded. In southern Greenland, the Neoglacial Narssarssuaq stade marks an older re-advance that exceeded the historical advance. The dating of the Narssarssuaq stade has been much debated. Here we present new radiocarbon dates from a sediment core collected from a small lake within the moraines formed during this stade. A minimum age for the Narssarssuaq stade of around 1200 yr BP is suggested from the dates.

    Spatial heterogeneity of land cover response to climatic change in the Nilgiri highlands (Southern India) since the last glacial maximum (2007)
    Sage Publications
    Details
    Publication Date: 2007-02-01
    Description: Fourteen hillslope soil profiles were sampled under natural vegetation (ie, grassland or forest) and plantations in the Nilgiri highlands, Southern India. Delta13C ratios were measured at different depths and14C ages determined for six profiles. In these highland soils where the turnover rate of organic matter is extremely low, the δ13C ratios of entire soil profiles have recorded signatures of past land cover. By correlating the data with results previously obtained from peat bogs and with knowledge concerning the history of human settlement, we distinguish three contrasting trajectories of palaeoenvironmental history and landscape change since the last glacial maximum. In the Central Nilgiris, between 18 and 10 ka BP, forest expansion occurred through the conjunction of a wetter climate (the maximum of southwest monsoon-related humidity occurring at c. 11 ka BP) and higher temperatures; since 10 ka BP, the reversal towards grassland vegetation is attributed to drier conditions. In the Western Nilgiris, where strong southwest monsoon winds permanently restrict forest patches to sheltered valley sites, steady but limited expansion of forest from 18 ka BP to the present is recorded and attributed to rising temperatures. The Southern and Eastern Nilgiris, where the northeast monsoon contributes 20% of the annual rainfall, are the less sensitive to fluctuations in the southwest monsoon. In these areas, rapid and extensive expansion of forest occurred mainly as a consequence of higher temperatures from 18 ka BP to the present. Massive deforestation by Badaga cultivators and Europeans planters followed after the sixteenth century AD.As a result, and in contrast with the Western Nilgiris where the land cover mosaic has remained remarkably stable in the last 18 ka BP, the current landscape differs sharply from the land cover pattern detected by the soil record.

    Geomorphic process-disturbance corridors: a variation on a principle of landscape ecology (2001)
    Sage Publications
    Details
    Publication Date: 2001-06-01
    Description: The paradigm of landscape ecology describes a landscape as a mosaic of landscape elements including the matrix, patches and corridors. Corridors are described as linear disruptions to the matrix, produced by anthropogenic actions or by streams which produce riparian corridors. Snow avalanches and debris flows are other geomorphic processes that should be considered as geomorphic process corridors rather than as disturbance patches. They possess requisite linearity, and they accomplish the five functions of a corridor: habitat, conduit, filter, source and sink. The definition of corridor in landscape ecology should be modified to embrace the concept of geomorphic process corridors.

    The hydrogeomorphological e•ects of beaver dam-building activity (1998)
    Sage Publications
    Details
    Publication Date: 1998-06-01
    Description: A characteristic of beaver ecology is their ability to build dams and, thus, to modify the landscape to increase its suitability for their occupation. This ability gives beaver great significance as a geomorphic agent. In order to review the hydrogeomorphological effects of beaver dam-building activity, this article places a context on the likely distribution and magnitude of beaver activity by considering the spatial and temporal variability of distributions of beaver and the habitat characteristics which might favour the establishment of substantial beaver populations. A description is then given of the nature and potential dimensions of instream structures built by beaver and the environmental conditions under which dam building has been observed to occur. The hydrogeomorphological impact of dam building is then appraised both locally and at the landscape scale, illustrating the very significant process modification caused by beaver. While the European beaver, Castor fiber, is the main focus of this review, it necessarily draws extensively on the much larger literature concerning the North American beaver (Castor canadensis).

    Periglacial research in Africa: past, present and future (1998)
    Sage Publications
    Details
    Publication Date: 1998-09-01
    Description: With global periglacial geomorphology undergoing significant advancements, it is appropriate to review the past and current status of such research in Africa. A brief historical overview of research outputs and approaches is presented for the respective African regions. Potential future quantitative periglacial research needs and approaches identified for Africa include: the examination of active periglacial processes, the identification of landforms and ground-ice forms, the potential for environmental change and the palaeoenvironmental reconstruction, and the application of periglacial studies.It is demonstrated that while periglacial geomorphology has progressed significantly in southern Africa, there has been little or no advancement elsewhere on the continent over the last two decades. None the less, on a more positive note, it is concluded that Africa has considerable potential in future global periglacial research.

    Applications of remote sensing, GIS and GPS in glaciology: a review (2001)
    Sage Publications
    Details
    Publication Date: 2001-12-01
    Description: Remote sensing has served as an efficient method of gathering data about glaciers since its emergence. The recent advent of Geographic Information Systems (GIS) and Global Positioning Systems (GPS) has created an effective means by which the acquired data are analysed for the effective monitoring and mapping of temporal dynamics of glaciers. A large number of researchers have taken advantage of remote sensing, GIS and GPS in their studies of glaciers. These applications are comprehensively reviewed in this paper. This review shows that glacial features identifiable from aerial photographs and satellite imagery include spatial extent, transient snowline, equilibrium line elevation, accumulation and ablation zones, and differentiation of ice/snow. Digital image processing (e.g., image enhancement, spectral ratioing and automatic classification) improves the ease and accuracy of mapping these parameters. The traditional visible light/infrared remote sensing of two-dimensional glacier distribution has been extended to three-dimensional volume estimation and dynamic monitoring using radar imagery and GPS. Longitudinal variations in glacial extent have been detected from multi-temporal images in GIS. However, the detected variations have neither been explored nor modelled from environmental and topographic variables. GPS has been utilized independent of remote sensing and GIS to determine glacier ice velocity and to obtain information about glacier surfaces. Therefore, the potential afforded by the integration of nonconventional remote sensing (e.g., SAR interferometry) with GIS and GPS still remains to be realized in glaciology. The emergence of new satellite images will make remote sensing of glaciology more predictive, more global and towards longer terms.

    Geomorphometry -diversity in quantitative surface analysis (2000)
    Sage Publications
    Details
    Publication Date: 2000-03-01
    Description: A widening variety of applications is diversifying geomorphometry ( digital terrain modelling), the quantitative study of topography. An amalgam of earth science, mathematics, engineering and computer science, the discipline has been revolutionized by the computer manipulation of gridded terrain heights, or digital elevation models (DEMs). Its rapid expansion continues. This article reviews the remarkable diversity of recent morphometric work in 15 selected topics and discusses their significance and prospects. The quantitative analysis of industrial microsurface topography is introduced to the earth science community. The 14 other topics are Internet access to geomorphometry; global DEMs; DEM modelling of channel networks; self-organized criticality; fractal and wavelet analysis; soil resources; landslide hazards; barchan dunes; harvesting wind energy; sea-ice surfaces; sea-floor abyssal hills; Japanese work in morphometry; and the emerging fields of landscape ecology and image understanding. Closing remarks note reasons for the diversity within geomorphometry, speculate on future trends and recommend creating a unified field of surface representation.

    Policy ideas and policy learning about 'basic research' in South Korea (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: ‘Basic research’ is based on epistemological and intentional criteria. In terms of science policy, however, these criteria imply contradictory views on investment in ‘basic research’. The former espouses the linear model of innovation and encourages policy-makers concerned with economic problems to expand investment on basic research. However, the latter can collide with the policy norm of policy-makers and discourage investment in ‘basic research’ in an institutional setting where the nation-state prevails over scientists, as in South Korea. Emphasizing policy ideas and policy learning, this paper empirically shows that changes in investment priority and the emergence of new concepts about ‘basic research’ are co-products of a policy paradigm of the linear model and a policy norm of industrial competitiveness in Korea. Specifically, emphasis was placed on the balance between pure and oriented basic research, but moved on to ‘oriented basic research’, ‘basic engineering’, and to ‘basic research’ coupled with ‘woncheon-technology’.

    Collaborative research for academic knowledge creation: How team characteristics, motivation, and processes influence research impact (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: Contending that collaboration management practices and interpersonal relationships are the main factors in successful collaboration in R&D, scholars have turned their attention to the relationships between collaborators. Internal factors in research collaboration activities are not yet understood at the team level. They are the so-called black box of collaboration study. The purpose of this paper is to empirically demonstrate how factors relating to team characteristics, motivation, and processes influence research impact. The study works from a multi-theoretical perspective, extending from behavioral science to general management study, and seeks to answer the question: How should we organize and manage a collaborative team to improve its research impact? The empirical results show that, along with previously identified qualitative and quantitative factors, input factors such as: project motivation, transformational leadership, frequent face-to-face communication, more outsourcing, more attentional resource, and more evenly distributed workload improve research impact.

    Why do international research collaborations last? Virtuous circle of feedback loops, continuity and renewal (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: It is often argued that the unintended consequences of science policy transformation over the last 50 years—increased role of fixed-term project funding, evaluation and temporary contracts—are short-termism, fragmentation and limited freedom to choose research topics and collaborators. This paper focuses on a phenomenon that should be highly unlikely in this context: long-term international research collaborations lasting over 10 and 20 years which remain creative and productive. To shed light on the little studied topic of why and how long-term international research collaborations evolve, the paper develops a mid-range theory from multiple longitudinal case studies. It suggests that long-term collaborations combining formal and informal interactions operate as virtuous circles whereas earlier results ensure feedback loops and thematic and organisational continuity, but renewal is crucial. The emergent theory is built from multiple data sources and methods analysing international collaborations in the emerging field of nanosciences in Europe.

    A cross-national environmental cluster collaboration: Shifting between an analytical and management level of the triple helix (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: The STInno project, which was part of the EU Framework Programme 7 aimed to minimise the distance between south–north regions in Europe with a specific focus on wastewater treatment clusters. Three triple helix collaborations from three different countries participated, using their knowledge to work on a case study of olive mill wastewaters. The objective of this paper was to study how the triple helix functioned in practice. Results showed that a management model of the triple helix is somewhat different from the analytical model. A shift between these two views occurred during the project and the participants had to relate to this, as it had an effect on the outcomes. Concepts of social capital and trust are used to further elaborate on this by emphasising the importance of the people side of the triple helix and how the original, analytical model can be limiting when used in management practice.

    Openness determinants of national research funding programmes in EU27 (2015)

    Publication Date: 2015-08-08
    Description: We empirically study how the characteristics of research and innovation systems influence the openness of national research funding programmes as regards the availability of funding to non-resident researchers. Based on a unique data set of national R&D programmes in the EU27 we identify a number of country-specific factors. These factors determine the degrees of programme openness observed when controlling for programme features in a hierarchical estimation model. Interestingly, we find that the quality and performance of national research add to the explanation of programme openness, whereas national integration into EU funding and research collaboration does not.

    Why did the Portuguese economy stop converging with the OECD? Institutions, politics and innovation (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-22
    Description: Underlying the crisis affecting peripheral European countries is their structural, long-term loss of competitiveness (Hadjimichalis, 2011, European Urban and Regional Studies , 18: 254–274). This article will focus on the Portuguese case and discuss the institutional constraints that hindered its economy from transitioning towards the production of higher-value added goods and services. It will discuss institutions as the product of a political process laden with power asymmetries and argue that the dominance of a relatively small community at the heart of economic and political life in Portugal has conditioned the development of the economy as a whole. Using this framework, this article will then contribute to the literatures on innovation and technological modernisation and argue that alongside a technical process of catching up there is a political process that can enable or constrain development.

    The geography of financial inclusion across Europe during the global crisis (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-22
    Description: This article identifies the main determinants of financial inclusion, defined as the probability of using both banking and credit services, across 18 Eastern European economies and 5 Western European ‘comparator’ countries. We elicit demographic and socio-economic information on 25,000 European households from the second round of the Life in Transition Survey undertaken during the 2008–2010 global crisis; the survey also includes several questions on households’ financial decisions collecting data at the regional and local level. Our results show that households hit by negative job or income shocks and without any asset to pledge are less likely to be financially included, especially in Eastern Europe. The individual likelihood of financial inclusion is also affected by the average use of financial services at the local level suggesting the presence of a financial multiplier effect. These results provide useful information for mapping financial inclusion across Europe during the crisis, which in turn can inform policy action at the local level.

    Negotiated expertise in policy-making: How governments use hybrid advisory committees (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: By linking the realms of public policy-making, science and the public, advisory committees that include academics, state representatives and societal stakeholders answer to a double challenge that governments face today: a need for technical knowledge and an increasing demand for public acceptance and accountability. In contrast to purely scientific policy advice, little theoretical attention has so far been paid to these hybrid advisory committees. Drawing on and adapting research on knowledge utilisation, theories of delegation, decision-making and governance, an analytical framework of the use of multi-source, negotiated expertise will be developed and applied to four cases set up by the German Federal Government with mandates in social policy and in science and technology policy. The study shows the committees’ pronounced governance potential, which builds on their political and epistemic authority. It describes two distinct dynamics that lend the committees to instrumental, problem solving, and symbolic, substantiating purposes.

    Stakeholder-led knowledge production: Development of a long-term management plan for North Sea Nephrops fisheries (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: This paper investigates how different kinds of knowledge are mobilised in interactions between the stakeholders, scientists and bureaucrats who are involved in EU fisheries management. It reports on an initiative led by the North Sea Regional Advisory Council aimed at making a long-term management plan for Nephrops fisheries in the North Sea. The sharing of knowledge between the actors is explored using insights from organisation management, focusing on the kinds of resources and efforts that are needed at different boundaries to allow knowledge sharing and knowledge production to occur. The findings point to the challenge of reaching a common understanding between actors when both novelty and high stakes are involved. Experiences gained during this pioneering initiative raise questions about how far it is possible to take a ‘bottom up’ collaborative process aimed at developing management instruments within a setting where there are conflicts of interests between the stakeholders involved.

    Integrating the supply and demand sides of public support to new technology-based firms (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: This paper analyses public support and argues that supply does not match demand in terms of the support needs of different types of new technology-based firms (NTBFs). The demand side of public support to NTBFs is analysed by developing a typology of NTBFs, based on venture origin and degree of innovativeness. Each type’s characteristics, challenges and support needs are identified. The supply side is analysed in terms of the goals, instruments and level of aggregation of the two main policy areas that provide support for NTBFs: small and medium-sized enterprise policy and science, technology and innovation policy. Finally, the demand and supply sides are compared and three main shortcomings of existing public support to NTBFs are identified. This paper makes a twofold contribution: first, the typology gives guidelines for policy-makers with respect to the support needs of the NTBFs. Second, it identifies shortcomings in existing public support and recommends improvements.

    Characterizing and comparing innovation systems by different 'modes' of knowledge production: A proximity approach (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: Though the concept of innovation systems has become influential in both academia and policy-making, an analytical approach to understanding innovation systems is still lacking. In particular, there is no analytical framework to measure ‘Mode 1’ and ‘Mode 2’ knowledge production. We propose a framework based on the proximity concept. Mode 1 and Mode 2 knowledge production are characterized by collaborations with cognitive, organizational, social, institutional and geographical proximity, and distance, respectively. Using a gravity model approach we apply our framework to the case of type 2 diabetes research and provide a characterization of the global innovation system and a comparative analysis of the North American and European innovation systems. Our main results hold that although collaborative research on type 2 diabetes generally follows a logic of proximity and hence is not characterized as Mode 2, important differences and similarities exist between the North American and European innovation systems.

    Epistemic integration of the European Research Area: The shifting geography of the knowledge base of Finnish research, 1995-2010 (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: The integration of national research systems is one of the central objectives of European research policies. Yet the epistemic objectives of this project have been poorly defined, and scant attention has been paid to whether political, social and financial integration of the European Research Area (ERA) is accompanied by epistemic integration. We discuss the conceptual framework and methodological practices to monitor research integration, and conclude that most of them, such as research collaboration, are only partial indicators of it. To augment existing approaches with an analysis of epistemic integration, we analyse the geographical sources of knowledge of Finnish research in the period 1995–2010. We show a broad shift towards a European knowledge base, demonstrating epistemic integration into the ERA, and that Finnish researchers are, paradoxically, sourcing knowledge from an increasingly distributed system of European knowledge hubs. As policy implications, we recommend clarifying the ERA’s epistemic objectives and redefining its strategy of ‘reducing fragmentation’.

    Research collaboration in the social sciences: What factors are associated with disciplinary and interdisciplinary collaboration? (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-08
    Description: Attention is increasingly directed toward better understanding the factors driving collaborations among researchers, particularly between researchers from different disciplinary backgrounds. This study investigates factors associated with disciplinary and interdisciplinary research collaboration in the social sciences. We utilize data from a survey of Australian-based social scientists. Interdisciplinary collaboration constitutes a considerable proportion of social scientists’ collaboration activity. Factors linked to the duration and diversity of research careers are positively associated with participation in collaborations. Job experience in Australian and foreign universities also boosts total collaboration, while holding an international citizenship increases interdisciplinary collaboration. Interdisciplinary collaborations are also associated with researcher orientation toward applied research activity. Investment in social science research is important for maintaining existing interdisciplinary and applied collaborations, although better information on these collaborations is desirable. Measures to expand such collaborations should take career stage into account. Broad-based population policies may also be an important underlying factor supporting international collaboration.

    The economic effects of owner distance and local property management in US office markets (2016)
    Oxford University Press
    Details
    Publication Date: 2016-07-13
    Description: Using a large dataset of US offices we analyse the relationship between investors’ distance to their assets and the effective rent of these assets, and study the extent to which property managers can influence this relationship. We construct hedonic rent models to control for other known rent determinants. It turns out that proximity matters: holding everything else constant, investors located closely to their office buildings are able to extract significantly higher effective rents from these assets, especially if these buildings are of low quality. This effect is due to significant differences in occupancy levels. Interestingly, property managers can affect this relationship, mitigating the adverse effects of investor distance on effective office rents. Especially if the owner does not reside in the same state as the building, external property management is of importance, most prominently so for class-B office buildings.

    Exporting to Russia? Entry barriers for food suppliers in a territory in transition (2016)
    Oxford University Press

    Publication Date: 2016-07-13
    Description: This article draws on extensive fieldwork conducted in Central Asia to explore food exports to Russia. It takes its theoretical starting point in global value chain theory and pinpoints chain entry barriers relating to financing, transportation and standards. The article also proposes rethinking the aspects of territoriality and institutional context, and suggests their integration into one concept, or rather a process of contextualizing territories. In doing so, the article argues for a methodology that not only examines current events, but also captures change as particularly important in what we term the territory in transition examined here.

    Regions and material flows: investigating the regional branching and industry relatedness of port traffics in a global perspective (2016)
    Oxford University Press
    Details
    Publication Date: 2016-07-13
    Description: This article proposes a quantitative analysis of the interdependencies between port specialization and regional specialization across the world. A global database is elaborated, covering about 360 port regions in both developed and developing countries. One goal is to verify how interdependent port traffic and regional characteristics are, in a context of increasingly flexible commodity and value chains. Despite the aggregated dimension of available data and the heterogeneity of local situations, the main results confirm the affinity between the primary sector and raw materials traffic, and between the tertiary sector and general cargo traffic, whereas the industrial sector offers mixed evidence. This allows us to address fundamental questions raised by both economic geography and regional science about transport and local development. The global typology of port regions points to certain regularities in their spatial distribution, and the article discusses the policy implications of particular cases.

    Towards a typology of repositioning strategies of GVC/GPN suppliers: the case of functional upgrading and downgrading (2016)
    Oxford University Press
    Details
    Publication Date: 2016-07-13
    Description: This article examines various upgrading and downgrading repositioning firm strategies within global value chains (GVCs) or global production networks (GPNs). It builds upon recent evidence that the mode of governance could vary profoundly among firms engaged in the same GVC/GPN. Therefore, the relevance of particular types of upgrading that were originally derived from the ideal types of GVC/GPN governance will be reconsidered. It is argued that the existing dissonance in the literature over possibilities for functional upgrading can be attributed to the different modes of governance that can exist within a particular GVC/GPN and to the diverse nature of functional upgrading. Consequently, a typology of functional upgrading is outlined, and it is argued that these different types vary significantly according to their probability and potential risk-benefit ratios. The article also introduces passive, adaptive and strategic downgrading and outlines their potential negative and positive effects on firms.

    Infrastructure as a traded product: A relational approach to finance in practice (2016)
    Oxford University Press
    Details
    Publication Date: 2016-07-13
    Description: As nations continue to grapple with growing infrastructure demand, financial markets will play an increasingly prominent role in the landscape for urban infrastructure. Yet existing literature tends to depict the ‘financialization’ of urban infrastructure assets as a restless move towards market efficiency aided by the growing transparency of financial information. This article offers a different view, showing how the spatial richness of financial data for infrastructure has progressed towards what we term a more permanent state of ‘informational translucency’. We draw on 53 interviews with participants in the market for infrastructure investment to present this more complicated picture of infrastructure finance, thereby elaborating a more granular understanding of how information flows through and shapes financial market geography. From this we propose a relational model that contributes to theoretical understandings of how financial products are intermediated over time and space.

    Estimating the impact of Mexican drug cartels and drug-related homicides on crime and perceptions of safety (2016)
    Oxford University Press
    Details
    Publication Date: 2016-07-13
    Description: We estimate the impact of drug cartels and drug-related homicides on crime and perceptions of security in Mexico. Since the location where drug cartels operate might be endogenous, we combine the difference-in-difference estimator with instrumental variables. Using surveys on crime victimization we find that people living in areas that experienced drug-related homicides are more likely to take extra security precautions. Yet, these areas are also more likely to experience certain crimes, particularly thefts and extortions. In contrast, these crimes and perceptions of insecurity do not change in areas where cartels operate without leading to drug-related homicides.

    The evolution of municipal structure (2016)
    Oxford University Press
    Details
    Publication Date: 2016-07-13
    Description: In most US states, urban expansions are governed by ‘popular determination’, under which residents make annexation decisions through referendum. Yet little research analyzes how urban spatial structure evolves under this system. We develop a model to examine how urban residents’ collective decisions on annexations and property taxes and their interactions with agricultural landowners affect municipal structure under popular determination. We find that the evolution process of an urban area can be divided into four stages similar to human life stages (infancy, juvenile, adulthood and maturity), characterized by the pace of development. The key parameters that determine urban spatial structure include agricultural rents, construction costs, interest rate, and the rate and uncertainty of income growth. Cities tend to be more spread-out and consist of a large number of smaller municipalities, in regions with lower agricultural land rents, lower construction costs, and lower rate and uncertainty of income growth.

    Small and medium-sized enterprises, intellectual property, and public policy (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-07
    Description: The objective of this paper is to study the use of intellectual property (IP) rights by small and medium-sized enterprises (SMEs). The paper draws on different surveys and studies in selected countries, with an emphasis on Canadian SMEs, to compare the use and exploitation of IP by company size. The paper finds that despite the potential benefits of acquiring formal IP rights for SMEs, they use IP rights to a lesser degree than large companies due to several factors, mainly the low rate of innovation compared to large companies and the cost and complexity of the IP system. The paper also presents a framework to analyze whether there is a role for government to play in this area, and how the government could address this under-utilization of IP rights by SMEs.

    Interdisciplinary research and geography: Overcoming barriers through proximity (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-07
    Description: Contributions on interdisciplinary research have so far focused on barriers to such collaborations and strategies for overcoming these. In this paper, we propose that a geographical perspective contributes to understand the formation of successful interdisciplinary research collaborations. The empirical analysis of a centre for clinical cancer research illustrates the importance of considering the role of geographical proximity to collaborators and decision-makers, as well as the co-location of excellent research groups within different fields, in overcoming barriers to interdisciplinary research. We suggest that policies aimed at stimulating lasting interdisciplinary research collaborations should take the distance between collaborators into account.

    Education, training and skills in innovation policy (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-07
    Description: The main question that guides this paper is how governments are focusing (and must focus) on competence building (education, training and skills) when designing and implementing innovation policies. After a brief literature review, this paper suggests a typology of internal/external and individual/organizational sources of competences that are related to innovation activities. This serves to examine briefly the most common initiatives that governments are taking in this regard. The paper identifies three overall deficiencies and imbalances in innovation systems in terms of education, training and skills: the insufficient levels of competences in a system, the time lag between firms’ short-term needs for specific competences and the long time required to develop them, and the imbalances between internal and external sources of competences in firms. From these, the paper elaborates a set of overall criteria for the (re)design of policy instruments addressing those tensions and imbalances.

    Ex-ante evaluation of publicly funded R&D projects: Searching for exploration (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-07
    Description: Ex-ante evaluation of publicly funded R&D projects is a very important part of the public funding process. The main purpose of the ex-ante evaluation process is to rate and choose which R&D projects the public program wishes to support financially. Publicly funded R&D projects in the energy sector can contribute to the further development of explorative and existing energy technologies that meet climate challenges. The aim of this paper is to investigate the ex-ante evaluation process of a Danish energy program with regard to exploration. The paper applies a qualitative approach, combining in-depth interviews with an observation study of 34 project evaluations. The findings show that there is a divergence and confusion between what the informants think constitutes the main purpose of the program, the ex-ante evaluation process, and the level of exploration. The policy implications can help to improve the ex-ante evaluation process of publicprograms.

    The evolving role of collaboration in developing scientific capability: Evidence from Korean government-supported research institutes (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-07
    Description: Scholars have emphasized the role of collaboration for the development of scientific capability and economic growth in developing countries. However, due to the difficulty in obtaining the appropriate evidence, there has been little empirical research on the role of collaboration in developing countries. The purpose of this study is to analyze the evolving collaboration strategy of Korea’s government-supported research institutes (GRIs). Using 44 years of bibliographic data, our analytic framework, which considers the dependence and diversity in knowledge creation, established three main findings. First, the transition of knowledge inflow into the competency of research organizations in developing countries requires the drive of the government along with the internalization of knowledge. Second, universities play an important role in sharing knowledge as scientific capability grows. Third, the role of GRIs with regards to collaboration changes as the scientific capability of external R&D entities and policy directions change.

    Shale gas: Energy innovation in a (non-)knowledge society: A press discourse analysis (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-07
    Description: For years, technological innovations have been the cause of controversy. In reaction to this, increasingly often the bodies responsible for implementing these innovations undertake social dialogue with stakeholders. An important environment for this is media discourse, which defines the problems and key actors and disseminates strategies for argumentation. Effective communication on public policies is one of the challenges in deliberative democracy. This paper aims to analyse the role of experts and knowledge in reference to the models of public communication on shale gas. Using a qualitative press analysis, an incoherence was observed in the understanding of knowledge and the profile of experts and the models of communication using them. The communication, which is rather oriented towards persuasion without legitimisation of scientific factual knowledge, fails. Reference in the discourse to the unknown or uncertain directs attention to the issues related to the strategic exploitation of nonknowledge.

    What do scientists think about the public and does it matter to their online engagement? (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-07
    Description: A survey of a large, US-based science organization with members from a range of disciplines ( n = 431) found relatively positive views about the public but such views were largely unrelated to past online engagement or willingness to engage in the future. Social norms, efficacy, and a desire to contribute to the public debate were the primary correlates of engagement. The research aims to provide quantitative evidence about how specific attitudes might limit scientists’ willingness to communicate with the public online in the context of recent calls to scientists to take a more active role in public debates about policy involving scientific issues. It highlights substantial remaining uncertainty about the drivers of engagement and the attendant need for ongoing research.

    Railroads, factor channelling and increasing returns: Cleveland and the emergence of the American manufacturing belt (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-14
    Description: American Manufacturing Belt (AMB) emergence has been used by NEG theorists as a prime example of how increasing returns foster industrial concentration. Other studies suggest the AMB was in place before increasing returns became established. This study examines this previously unrecognized contradiction. An analysis of Cleveland, one of the fastest growing of AMB cities, is undertaken using new data sources. This finds the railroad sector crucial in generating direct employment and stimulating related industrial investment through forward and backward linkages. The former are associated with ‘factor channeling’—planned strategies to direct raw material flows to the city. NEG theorists’ under-emphasis on raw material provision and their use of the iceberg model to avoid analysis of the railroad sector is therefore found to be erroneous. The increasing returns hypothesis is evaluated using new data for several industrial sectors and rejected as a valid explanation for early manufacturing growth in Cleveland.

    Description: Using data on 418 Norwegian firms, the results confirm the hypotheses that innovative/radically innovative firms tend to be more involved in international personal and formal networks than non-innovative/incrementally innovative ones. While regional and national networks are much more widespread than international ones, they are not significantly positively associated with innovation. International personal networks and international links with suppliers and customers and with universities and research institutions, as well as global buzz with strangers, are positively related to innovation. This suggests that innovation management and policy, in particular in countries with a limited national innovation base, could benefit from facilitating certain international networks.

    Culture, spatial diffusion of ideas and their long-lasting imprints--evidence from Froebel's kindergarten movement (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-14
    Description: We document the spatial diffusion of Friedrich Froebel’s radical invention of kindergartens in 19th-century Germany. The first kindergarten was founded at Froebel’s birthplace. Early spatial diffusion can be explained by cultural proximity, measured by historical dialect similarity, to Froebel’s birthplace. This result is robust to the inclusion of higher order polynomials in geographic distance and similarity measures with respect to industry, geography or religion. Our findings suggest that a common cultural basis facilitates the spill-over of ideas. We further show that the contemporaneous spatial pattern of child care coverage is still correlated with cultural similarity to Froebel’s place of birth.

    Description: Our article contributes to the emerging micro-level strand of the literature on the link between local variations in weather shocks and conflicts by focusing on a pixel-level analysis for North and South Sudan between 1997 and 2009. Temperature anomalies are found to strongly affect the risk of conflict, whereas the risk is expected to magnify in a range of 24–31% in the future under a median scenario. Our analysis also sheds light on the competition over natural resources, in particular water, as the main driver of such relationship in a region where pastoralism constitutes the dominant livelihood.

    Accuracy and efficiency in simulating equilibrium land-use patterns for self-organizing cities (2015)
    Oxford University Press
    Details
    Publication Date: 2015-06-20
    Description: Lucas and Rossi-Hansberg (L&RH) (2002, Econometrica , 70: 1445–1476) and Fujita and Ogawa (F&O) (1982, Regional Science and Urban Economics , 12: 161–196, 1989, Environment and Planning A , 21: 363–374) develop urban models in which economic activity self-organizes due to spillovers in production. However, F&O (1982, Regional Science and Urban Economics , 12: 161–196, 1989, Environment and Planning A , 21: 363–374) show that rents and employment density are flat or falling as the city center is approached, while in the simulations of L&RH (2002, Econometrica , 70: 1445–1476), rents rise at an increasing rate toward the center suggesting a concentration of employment near the center. For the Lucas and Rossi-Hansberg model, we prove that land rents and density must be flat or falling near the center. We explain how using a polar coordinate system when approximating a two-dimensional integral can create systematic imprecision in their simulations, and then present revised simulations. The proofs and simulations suggest that in urban models where economic activity self-organizes firms do not unduly cluster at the center of a central business district even in monocentric equilibria.

    Publication Date: 2015-10-14
    Description: To analyse the mutually dependent relationship between local economic performance, demand for and supply of transport services, we employ the structural panel VAR method that is popular in the macroeconomic literature, but has not previously been applied to the modelling of the within-city dynamics of transportation. We focus on a within-city panel of Berlin, Germany during the heyday of the construction of its dense public transit network (1890–1914). Our results suggest that economic outcomes and a supply of transport infrastructure mutually determine each other. We find a short-run (long-run) elasticity of property prices with respect to transport supply of 2% (8.5%). Both transport demand and supply seem to be driven more by firms than by residents.

    Transnational corporations shaping institutional change: the case of English law firms in Germany (2015)
    Oxford University Press
    Details
    Publication Date: 2015-10-14
    Description: Questions remain about the factors that influence the ability of transnational corporations (TNCs) to shape processes of institutional change. In particular, questions about power relations need more attention. To address such questions, this article develops a neo-institutional theory-inspired analysis of the case of English law firms and their impacts on institutional change in Germany. The article shows that the shaping of the direction of institutional change by English legal TNCs was a product of conjunctural moments in which local institutional instability combined with the presence, resources and strategies of the TNCs to redirect the path of institutional evolution. This draws attention to the need to go beyond the TNC and its resources and to consider the way a diverse array of local actors and their generating of instability in existing institutional structures influence the ability of TNCs to become involved in processes of institutional change in particular, conjunctural moments in time.

Major airports anchor significant concentrations of employment which average one-third to one-half the size of the respective CBDs, depending upon the operationalization, while 80% of the airports anchor employment agglomerations. Airport cities are anchored by airports but not driven by aviation. The relationship between spatial form and economic function suggests that need for airport access determines the location of transportation-providing employment while spatial employment filtering, based on urban land costs and agglomeration benefits, are responsible for the presence of transportation-supporting and transportation-using employment, such as producer services.

    The role of major infrastructure in subregional economic development: an empirical study of airports and cities (2015)
    Oxford University Press
    Details
    Publication Date: 2015-10-14
    Description: The link between airports, air service and regional economic development has been well-established and used to justify airport expansion at the expense of local communities because of subsequent region-wide benefits. However, local-level spatial analyses based on US Economic Census data indicate that economic benefits in terms of professional and administrative employment do not necessarily offset local economic and quality of life costs. Furthermore, arguments for an airport city or aerotropolis phenomenon in the US context ignore the individual histories and morphologies of metropolitan areas and overstate the influence an airport has on the economic development of its region.

    Cities and product variety: evidence from restaurants (2015)
    Oxford University Press
    Details
    Publication Date: 2015-10-14
    Description: This article measures restaurant variety in US cities and argues that city structure directly increases product variety by spatially aggregating demand. I discuss a model of entry thresholds in which market size is a function of both population and geographic space and evaluate implications of this model with a new data set of 127,000 restaurants across 726 cities. I find that geographic concentration of a population leads to a greater number of cuisines and the likelihood of having a specific cuisine is increasing in population and population density, with the rarest cuisines found only in the biggest, densest cities. Further, there is a strong hierarchical pattern to the distribution of variety across cities in which the specific cuisines available can be predicted by the total count. These findings parallel empirical work on Central Place Theory and provide evidence that demand aggregation has a significant impact on consumer product variety.

    Econometric modelling of the regional knowledge production function in Europe (2015)
    Oxford University Press
    Details
    Publication Date: 2015-10-14
    Description: By adopting a semiparametric approach, the ‘traditional’ regional knowledge production function is developed in three complementary directions. First, the model is augmented with region-specific time trends to account for endogeneity due to selection on unobservables . Second, the nonparametric part of the model relaxes the standard assumptions of linearity and additivity regarding the effect of R&D and human capital. Finally, the assumption of homogeneity in the effects of R&D and human capital is also relaxed by explicitly accounting for the differences between developed and lagging regions. The analysis of the genesis of innovation in the regions of the European Union unveils nonlinearities, threshold effects, complex interactions and shadow effects that cannot be uncovered by standard parametric formulations.

    The combined effects of age and seniority on research performance of full professors (2016)
    Oxford University Press
    Details
    Publication Date: 2016-06-16
    Description: In this paper we examine the relationship between research performance, age, and seniority in academic rank of full professors in the Italian academic system. Differently from a large part of the literature, our results generally show a negative monotonic relationship between age and research performance, in all the disciplines under analysis. We also highlight a positive relationship between seniority in rank and performance, occurring particularly in certain disciplines. While in medicine, biology, and chemistry this result could be explained by the ‘accumulative advantage’ effect, in other disciplines, like civil engineering, and pedagogy and psychology, it could be due to the existence of a large performance differential between young and mature researchers, at the moment of the promotion to full professors. These results, witnessed both generally and at the level of the individual disciplines, offer useful insights for policy makers and administrators in academia on the role of older professors.

    Too big to innovate? Exploring organizational size and innovation processes in scientific research (2016)
    Oxford University Press
    Details
    Publication Date: 2016-06-16
    Description: We explore the impact of organizational size in six federally funded research organizations on a range of organizational processes related to the pursuit of innovation. The data utilized consisted of 266 scientists drawn from 64 research projects across five programmatic research areas: alternative energies, biology, chemistry, geophysical sciences, and material sciences. A sixth project category was added to accommodate the highly interdisciplinary character of a handful of projects. Although the data had some limitations, it was found that organizational size had a negative impact on three categories of innovation processes: the amount of time spent in research and professional activities, how research time is spent, and exchanges of technical knowledge. In addition, some potential advantages of larger size, such as: greater research resources, better perceived managerial quality or a visionary strategy, were not found to be significant.

    Resilient science: The civic epistemology of disaster risk reduction (2016)
    Oxford University Press
    Details
    Publication Date: 2016-06-16
    Description: In this paper, we use insights from science studies to elucidate the nature of advisory science in the context of disasters, particularly those involving geophysical hazards. We argue that there are some key differences between disaster advisory science and the issues that are most discussed in science studies: they are both time- and space-specific and they constitute major social, economic and scientific shocks. We suggest that disasters require flexible advisory structures that maximise the co-production of science and social order, and present a framework for this. We argue that the aim of increasing resilience to natural hazards requires that sociology of scientific knowledge play a part in the application of scientific advice: disaster studies has focused on the reduction of vulnerability as a reaction against technical-rational models of scientific advice, but in doing so has restricted the potential role of the social sciences in the framing of scientific advice and expertise.

    How venture capitalists decide which new medical technologies come to exist (2016)
    Oxford University Press
    Details
    Publication Date: 2016-06-16
    Description: To encourage the commercial translation of biomedical discoveries, public policies increasingly seek to stimulate the venture capital industry. Very little is known, however, about the way venture capitalists assess the likely benefits new technologies may bring to clinical practice and healthcare systems. Drawing on a five-year fieldwork conducted in Quebec (Canada), which included in-depth interviews and document analysis, we explore why capital investors choose to invest in certain health technology-based ventures and how they influence the innovation process. Our findings clarify how capital investors: first, use market-oriented valuations when they pick and ‘coach’ technology entrepreneurs; second, act to transform and protect their investments; and finally, exert their authority along the technology development process. Current innovation policies should be carefully examined because capital investors’ understanding of the world in which they operate largely determines which health technologies make their way into healthcare systems and which may never come into existence.
