Description: Changes in agriculture, including simultaneous intensification and abandonment, have significantly shaped the evolution of rural areas. The assessment of resilience in agricultural systems could provide insights into the ability of many rural areas to survive and regain competitiveness following disturbances. The aim of this study is to use the adaptive cycle heuristic as a diagnostic tool to study dynamics of change in two agricultural sectors (durum wheat/sheep and goat farming) in the Basilicata region of Southern Italy over the last seventy years. The heuristic was applied through a participatory approach in a community of stakeholders who have conceived, in collaboration with researchers, the Manifesto “Let’s Think Basilicata” as a regional instrument of analysis and a laboratory of ideas and development of proposals. Despite some methodological difficulties, the adaptive cycle heuristic proved useful to describe processes of change in the socio-ecological system and could have enormous potential in shaping policy instruments for rural areas. However, much greater research is needed, both in terms of theory and methodology, before policy impacts on resilience in socio-ecological systems can be fully understood.

Description: The role of tourism in rural areas is pivotal for the integration and valorization of territorial resources and it is strengthened by the capacity to promote local community participation in processes of development. The paper addresses the issue by presenting and discussing a case study of a rural area of southern Italy where a territorial network for the development of local tourism has been set up. The innovative initiative aimed, firstly, to facilitate a closer connection between production and consumption by reducing transaction costs and, secondly, to connect local production with quality conscious consumers looking for traditional products. The network project also aimed to create conditions conducive to increasing the competitiveness of the local production chain and tourism sector. The case study shows how the challenge for many rural territories lies in increasing levels of trust and rebuilding social capital as a precondition of developing the tourism sector and fostering socio-economic development as a whole. Traditional institutions, as well as hybrid institutions, with the support of research organizations, can play a key role.

Description: Treatment options against periodontitis attempt to completely remove oral microbiota even if several species in dental plaque demonstrate protective features. Predatory bacteria that selectively predate solely on Gram-negative bacteria might be a viable therapeutic alternative. Therefore, the aim of this study is to in vitro evaluate the susceptibility of some oral pathogens to predation by B. bacteriovorus HD100 in liquid suspension. Cultures of prey cell were prepared in brain heart infusion broth (BHI) broth incubating overnight at the appropriate conditions for each organism to reach log phase of growth. Predatory activity was assessed by measuring optical density at 600 nm after 12, 24, 48 and 72 hours. Statistical analysis was performed using the Mann–Whitney U test and p values less than 0.05 were considered statistically significant. The study demonstrated that B. bacteriovorus is able to predate on aerobic species and on microaerophilic ones (p 〈 0.05) but also that its predatory capacity is strongly compromised by the conditions of anaerobiosis. B. bacteriovorus, in fact, was unable to predate the anaerobic species involved in the present study (F. nucleatum and P. gingivalis). The findings of the study suggest that B. bacteriovorus is able to tolerate microaerophilic conditions and that in anaerobiosis it cannot exert its predatory capacity. Such evidence could lead to its use as an agent to prevent recolonization of the periodontal pocket following therapy. Further studies are needed to investigate the activity of B. bacteriovorus against recently recognized periodontopathogens, alone or organized in biofilms of multi-species communities.

Description: Using a unique dataset of 50 listed companies that meet the majority of the OECD requirements for social impact investments, we construct a social impact finance stock index and investigate how investing in social impact firms can contribute to portfolio risk-return performance. We build portfolios with three different methodologies (naïve, Markowitz mean-variance optimization, GARCH-copula model), and we study the performance in terms of returns, Sharpe ratio, utility, and forecast premium based on a constant relative risk aversion function for investors with different levels of risk aversion. Consistent with the idea that social impact investment can improve portfolio risk-return performance, the results of our macro asset allocation analysis show the importance of a large fraction of investor portfolios’ stake committed to social impact investments.

Description: Sheepdogs’ visuospatial abilities, their control of prey-driven behavior and their motor functions are essential characteristics for success in sheepdog trials. We investigated the influence of laterality on 15 sheepdogs’ (Canis familiaris) spontaneous turning motor pattern around a herd and on their behavior during the first encounter with sheep in a training session. The most relevant finding of this research was that the dogs displayed significantly more aggressive behavior toward the sheep when turning in a counterclockwise direction around the herd. Considering that in counterclockwise turns the sheep were in the dogs’ left visual hemifield, the high frequency of aggressions registered during counterclockwise turns suggests right hemisphere main activation. Overall, our results revealed the existence of a relationship between motor lateralization and aggressive behavior in dogs during sheepdog training and have practical implications for sheepdog training.

Description: Adoption of soil conservation practices is promoted by increased engagement between researchers and stakeholders. By reporting a case study from southern Italy where farmers have been involved in research projects dealing with soil conservation over several years, we demonstrated that the rate of adoption of conservative technologies is positively linked to the degree of stakeholder participation in the project and that farmers (and other stakeholders) have been driven toward more conscious perception of the complex link between agricultural practices, environmental impacts and socioeconomic effects. The results of this study reinforce the pivotal role of effective participatory processes in soil conservation—evidencing the importance of (i) time required to build relationships and (ii) intensity (and persistence) of collaboration among similar initiatives. Empirical evidence highlights the need to combine different approaches to deal with soil degradation. As well as the participatory time length, the synergies between the methods utilized, and the range of interacting mind sets are also very important.

Description: Sustainability, Vol. 10, Pages 2237: Sustainability and Efficiency of the European Banking Market after the Global Crisis: The Impact of Some Strategic Choices Sustainability doi: 10.3390/su10072237 Authors: Francesca Pampurini Anna Grazia Quaranta In the last few years, financial managers, supervisors and policy makers have been collectively engaged on the role of the banking and financial sector in relation to environmental and sustainability issues. The efficiency level that characterizes the production process of banks and financial intermediaries is strictly interconnected with sustainability so that, from a long term perspective, cost and profit efficiency reveals to be one of the most important premises for sustainability. This work aimed to analyze the level of efficiency achieved by European banking groups to verify if some key drivers of efficiency deriving from strategic choices outlined by literature on single banks (i.e., size, number of branches, cost income ratio and geographical location) are the same when considering banking groups. The study is focused on the period 2011–2016 that is characterized by, at least, two critical events that occurred after the sub-prime crisis. The level of efficiency of each banking group was measured with the Stochastic Frontier Approach and then the units were clustered into three homogeneous sets. Observing these clusters, the results show that the groups belonging to some specific countries appear to be more efficient with respect to others. Moreover, the banking groups characterized by many branches and a high level of cost income ratio exhibit a medium level of efficiency. Eventually, the biggest banking groups are the least efficient.

Description: Materials, Vol. 11, Pages 1189: Screen Printed Pb3O4 Films and Their Application to Photoresponsive and Photoelectrochemical Devices Materials doi: 10.3390/ma11071189 Authors: Riccardo Panetta Simone Quaranta Alessandro Latini A new and simple procedure for the deposition of lead (II, IV) oxide films by screen printing was developed. In contrast to conventional electrochemical methods, films can be also deposited on non-conductive substrates without any specific dimensional restriction, being the only requirement the thermal stability of the substrate in air up to 500 °C to allow for the calcination of the screen printing paste and sintering of the film. In this study, films were exploited for the preparation of both photoresponsive devices and photoelectrochemical cell photoanodes. In both cases, screen printing was performed on FTO (Fluorine-Tin Oxide glass) substrates. The photoresponsive devices were tested with I-V curves in dark and under simulated solar light with different irradiation levels. Responses were evaluated at different voltage biases and under light pulses of different durations. Photoelectrochemical cells were tested by current density–voltage (J-V) curves under air mass (AM) 1.5 G illumination, incident photon-to-current efficiency (IPCE) measurements, and electrochemical impedance spectroscopy.

Description: Understanding the complementary specialisation of the canine brain has been the subject of increasing scientific study over the last 10 years, chiefly due to the impact of cerebral lateralization on dog behaviour. In particular, behavioural asymmetries, which directly reflect different activation of the two sides of the dog brain, have been reported at different functional levels, including motor and sensory. The goal of this review is not only to provide a clear scenario of the experiments carried out over the last decade but also to highlight the relationships between dogs’ lateralization, cognitive style and behavioural reactivity, which represent crucial aspect relevant for canine welfare.
