    Description: The 60–80s of the last century were the period of the most rapid development of commercial oceanology in the Azov and Black Sea Scientific Research Institute of Marine Fisheries and Oceanography (AzCherNIRO, further renamed YugNIRO). In addition to the monitoring of oceanographic processes, it was involved in the areas of general marine ecology, monitoring of marine pollution, and space oceanology. Oceanographic information is used in forecasting the state of aquatic ecosystems at various timescales and is crucial for fishing forecasts. In 1981, a satellite data reception center was established in AzCherNIRO. In the 80–90s, in YugNIRO, an optimal procedure was created for multidimensional predictive monitoring of the state of the Black Sea ecosystem. In September 1986, within the Laboratory of Commercial Oceanology of the Black Sea, a group for the conservation of marine ecosystems was created, which turned into a sector in January 1989, and into a separate laboratory in December 1996. Its reasearchers carried out multidisciplinary environmental studies, investigating the ecological status of the aquatic areas affected by the facilities of the marine industry during their operation, monitoring the level of soil contamination, and excercising the toxicological control of fish and fish products. YugNIRO oceanological studies conducted in the World Ocean from the early 1970s to the early 1990s made it possible to link the productivity and catches of exploitable species to the atmospheric circulation, changes in the climatic fields of currents, as well as to the geo- and heliophysical factors, which enabled the fishing predictions with a one-year lead time or more for the fishing areas of the Central, Southeastern and Southwestern Indian Ocean, the Patagonian Shelf, and the Indian Ocean sector of Antarctica. In the 70–90s and early 2000s, YugNIRO conducted marine geological studies facilitating fishing operations and environmental protection in the Gulf of Aden, on the bottom elevations of the tropical and subtropical parts of the Indian Ocean, in the Antarctic Shelf area, and in the Black and Azov Seas. This article lays down the current major goals and prospects of commercial oceanology.
    Description: 60–80-е годы прошедшего столетия были в АзЧерНИРО (ЮгНИРО) периодом наиболее активного развития промысловой океанологии. Кроме мониторинга океанографических процессов она начала внедряться в сферы общей экологии моря, мониторинга загрязнения моря, космической океанологии. Океанографическая информация используется при разработке прогнозов состояния водных экосистем различной заблаговременности и является неотъемлемой составляющей рыбопромысловых прогнозов. В 1981 г. в АзЧерНИРО был создан центр приема спутниковой информации. В 1980–1990-х гг. в ЮгНИРО была создана оптимальная для Черного моря схема комплексного прогностического мониторинга состояния его экосистемы. В сентябре 1986 г. в составе лаборатории промысловой океанологии Черного моря была создана группа, в январе 1989 г. — сектор, в декабре 1996 г. — лаборатория охраны морских экосистем. Сотрудниками лаборатории проводились комплексные экологические исследования состояния акваторий предприятий морехозяйственого комплекса в условиях их производственной деятельности, контроль уровня загрязненности почв, токсикологический контроль рыбы и рыбопродукции. Океанологические исследования ЮгНИРО, проводимые в Мировом океане с начала 1970-х до начала 1990-х гг., позволили получить систему связей урожайности и вылова промысловых объектов с особенностями атмосферной циркуляции, изменениями макромасштабных полей течений, гео- и гелиофизическими факторам для прогноза промысловых характеристик с заблаговременностью год и более в промысловых районах центральной, юго-восточной и юго-западной частей Индийского океана, в районе Патагонского шельфа, в индоокеанском секторе Антарктики. Выполнение морских геологических работ в рыбопромысловых и природоохранных целях проводилось ЮгНИРО в 1970–1990-х и в начале 2000-х гг. в Аденском заливе, на поднятиях тропической и субтропической частей Индийского океана, на шельфе Антарктиды, в Черном и Азовском морях. В статье формулируются основные современные цели и пути развития промысловой океанологии.

    Description: La producción de ostión en Cuba aumenta hacia el este, y los máximos de abundancia y captura se presentan en la zona costera cercana a la cuenca del río Cauto, en la región correspondiente al municipio Manzanillo, provincia de Granma. En esta región habitan el ostión de mangle antillano (Crassostrea rhizophorae Guilding, 1828), y el ostión americano (Crassostrea virginica Gmelin, 1791). Aunque la tendencia histórica ha sido al incremento, posterior a 2013 (853 t) la producción promedio anual disminuye a 307 t. El objetivo de esta investigación fue evaluar el estado actual del recurso ostión y su aprovechamiento industrial en la región del golfo de Guacanayabo, en relación a la situación ambiental de sus hábitats. Se realizó un diagnóstico de la pesquería de ostión y de la gestión ambiental de la pesca extractiva para determinar impactos ecosistémicos. Se identificaron como principales factores de impacto negativo, que inciden sobre las poblaciones de ostión y sus hábitats, el incumplimiento del periodo de veda, el manejo inadecuado de la pesca extractiva, y eventos de contaminación, que afectan los bienes y servicios ecosistémicos del manglar y reducen las poblaciones de ostión. Se propone la ostricultura artesanal como alternativa pesquera sostenible y se proyectó un plan de producción de ostión para 2023-2030. Se estimó que a calidad ambiental de la región donde se desarrollan las especies de interés es adecuada para su desarrollo.
    Description: Oyster production in Cuba increases to the east, and the maximum abundance and catch occur in the coastal zone near the Cauto river basin, in the region corresponding to the Manzanillo municipality, Granma province. The West Indian mangrove oyster (Crassostrea rhizophorae Guilding, 1828), and the American oyster (Crassostrea virginica Gmelin, 1791) inhabit this region. Although the historical trend has been to increase, after 2013 (853 t) the average annual production decreases to 307 t. The objective of this research was to evaluate the current state of the oyster resource and its industrial use in the region of the Guacanayabo Gulf, in relation to the environmental situation of its habitats. A diagnosis of the oyster fishery and the environmental management of extractive fishing was carried out to determine ecosystem impacts. The main factors of negative impact, which affect oyster populations and their habitats, were identified as non-compliance with the closed season, inadequate management of extractive fishing, and pollution events, which affect the goods and ecosystem services of the mangrove and reduce oyster populations. Artisanal oyster farming is proposed as a sustainable fishing alternative and an oyster production plan was projected for 2023-2030. It is estimated that the environmental quality of the region where the species of interest develop is adequate for their development.

    Description: To ensure the long-term sustainable use of African Great Lakes (AGL), and to better understand the functioning of these ecosystems, authorities, managers and scientists need regularly collected scientific data and information of key environmental indicators over multi-years to make informed decisions. Monitoring is regularly conducted at some sites across AGL; while at others sites, it is rare or conducted irregularly in response to sporadic funding or short-term projects/studies. Managers and scientists working on the AGL thus often lack critical long-term data to evaluate and gauge ongoing changes. Hence, we propose a multi-lake approach to harmonize data collection modalities for better understanding of regional and global environmental impacts on AGL. Climate variability has had strong impacts on all AGL in the recent past. Although these lakes have specific characteristics, their limnological cycles show many similarities. Because different anthropogenic pressures take place at the different AGL, harmonized multilake monitoring will provide comparable data to address the main drivers of concern (climate versus regional anthropogenic impact). To realize harmonized long-term multi-lake monitoring, the approach will need: (1) support of a wide community of researchers and managers; (2) political goodwill towards a common goal for such monitoring; and (3) sufficient capacity (e.g., institutional, financial, human and logistic resources) for its implementation. This paper presents an assessment of the state of monitoring the AGL and possible approaches to realize a long-term, multi-lake harmonized monitoring strategy. Key parameters are proposed. The support of national and regional authorities is necessary as each AGL crosses international boundaries.

    Description: This draft White Paper has been prepared as part of the Vision 2030 process of the United Nations (UN) Decade of Ocean Science for Sustainable Development (hereafter, Ocean Decade). The Vision 2030 process aims to identify tangible measures of success for each of the ten Ocean Decade Challenges by 2030. From a starting point of existing initiatives underway in the Ocean Decade and beyond, and through a lens of priority user needs, the process determines critical gaps in science and knowledge, needs for capacity development, priority datasets, infrastructure, and technology for each Challenge. Focusing investments in science and knowledge to address these needs will help ensure progress towards meeting each critical Challenge by the end of the Ocean Decade in 2030. The results of the process will contribute to the scoping of future Decade Actions, identification of resource mobilisation priorities, and ensure relevance of the Challenges over time. This draft White Paper is one of a series of ten White Papers, all of which have been authored by an expert Working Group and discussed at the 2024 Ocean Decade Conference. A synthesis report, authored by the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific, and Cultural Organization (UNESCO/IOC), will accompany the White Papers. With a substantial portion of people depending on the ocean as a primary source of nutrition and livelihood, a significant challenge comes into focus: How can we ensure that the ocean's resources continue to effectively nourish an expanding global population? The Ocean Decade responds to this critical concern through its Challenge 3: “Sustainably nourish the global population”.

    Description: This book analyzes the role of the argentine liberal-conservative intellectuality before the last dictatorship, kown as "Proceso de Reorganización Nacional" (1976-1983).
    Description: Published
    Description: El presente trabajo analiza el rol de la intelectualidad liberal-conservadora argentina ante la última dictadura, el "Proceso de Reorganización Nacional" (1976-1983). El libro estudia las posiciones e intervenciones de un conjunto de catorce actores: Álvaro Alsogaray, Alberto Benegas Lynch, Germán Bidart Campos, Horacio García Belsunce, Jorge Luis García Venturini, Mariano Grondona, Juan Segundo Linares Quintana, Mario Justo López, José Alfredo Martínez de Hoz, Víctor Massuh, Jaime Perriaux, Ambrosio Romero Carranza, Carlos Sánchez Sañudo y Ricardo Zinn. La elección de estos nombres implica considerar un abanico amplio de trayectorias que componen figuras intelectuales de diversidad, unidas sin embargo por muchos más vínculos que la adscripción política. La obra se interna en la historia político-intelectual de un espacio ideológico aún poco explorado desde los estudios sobre la intelectualidad, las derechas y la propia dictadura, reponiendo los diversos espacios ocupados por estos hombres, sus proyectos, coincidencias, polémicas y desencantos en un momento clave de la historia argentina.

    Description: Published
    Description: La Comisión Provincial por la Memoria (CPM) es un ente estatal, extra poderes, autónomo y autárquico, es decir, no gubernamental, que funciona en la provincia de Buenos Aires. Está compuesta, por un lado, por una comisión de “notables”, personas reconocidas socialmente que provienen de diferentes ámbitos ligados a las luchas por la memoria y la defensa de los derechos humanos y, por el otro, por un equipo técnico de trabajadores que llevan a cabo las tareas cotidianas de la institución. En este libro se indaga cómo fue la inscripción de la CPM en el campo de los derechos humanos y la memoria. Abordar esta agencia estatal en el marco de las lógicas de este campo permite ver con profundidad el proceso a través del cual la institución nació y en qué contexto político y social lo hizo. A su vez, puede observarse qué trayectorias y horizontes tenían sus creadores y qué estrategias institucionales guiaron su armado. Por último, el análisis de la CPM en funcionamiento permite reconocer que algunas de sus cualidades distintivas reflejan el modo en que la institución eligió inscribirse en las estructuras administrativas del Estado y en el campo, con los acuerdos y los conflictos que esto acarrea.

    Description: Due to their very low volatility, high thermal stability, and ability to dissolve a wide variety of compounds, ionic liquids appear to meet the rigorous criteria for industrial applications. Among other uses, ionic liquids appear to be efficient for gas capture, biomass pretreatment, separation problems, and electrochemistry. They are also used in electrolytes, as lubricants, catalysts, or as antistatic agents. This book discusses the various uses of ionic liquids. Chapters discuss such topics as the use of ionic liquids in batteries, new mono, di, and trimeric imidazolium and pyridinium ionic liquids as catalysts in organic chemistry, the physico-chemical properties of ionic liquid-substituted double-network gels for industrial applications, the use of paramagnetic ionic liquids in magnetic resonance imaging, the compatibility of filter materials used with ionic liquids, and the development of low-friction ion gels for industrial applications.

    Description: Most environmental analyses focus on changing existing processes to use less energy and produce fewer emissions. This report uses energy service analysis (ESA) to examine possibilities for instead changing how a service is delivered. The ESA framework is used to analyze how changes in the provision of two services—news delivery and personal mobility—might reduce greenhouse-gas emissions and suggests other areas in which ESA could be applied.

    Description: Desde la independencia hispanoamericana, los políticos continentales llevaron una vida intensa, afanosa y, en ocasiones contradictoria, en sus luchas por el poder. En diferentes circunstancias, actuaron como militares, periodistas, diplomáticos, abogados, profesores o escritores. Sus vidas simbolizan la antigua confrontación entre liberalismo y conservadurismo; centralismo y federalismo, cuyo destino dejó una impronta en el balance de poder regional. Este libro tiene como objetivo general introducirse a ese mundo de los políticos hispanoamericanos, y los problemas de la historia política continental del primer siglo de vida independiente, en particular en la región del Río de la Plata.

    Description: “Dilemas, apuestas y reflexiones teórico-metodológicas para los abordajes en Historia Reciente” se preocupa por presentar los dilemas teóricos y metodológicos, las potencialidades y la utilización de las fuentes para la escritura de la Historia Reciente, los condicionantes en las agendas académicas con el propósito de dejar explicitadas las preocupaciones con las que se trabaja en escritura de la historia del pasado reciente y dar cuenta cómo se construyen los objetos de estudio. El libro está organizado en dos partes. La primera dedicada a discutir conceptos, categorías y perspectivas teóricas, y la segunda orientada a reflexionar sobre posibilidades y limitaciones del heterogéneo y complejo universo de materiales utilizados en la escritura de los diferentes capítulos de ese pasado doloroso y que no pasa. No obstante esta división, los recorridos analíticos, teórico-metodológicos e historiográficos atraviesan todos los capítulos del libro, pero lo hacen desde aproximaciones disímiles, que aportan de manera significativa, sea a la reflexión crítica sobre cuestiones estructurantes de la investigación sobre el pasado reciente (la represión, sus dimensiones, modalidades y características; la militancia humanitaria, las relaciones entre violencia y política, los exilios; la temporalidad del pasado-presente; los trabajos de la memoria, la transmisión intergeneracional de pasados traumáticos), sea al conocimiento específico de capítulos concretos de la historia de las dictaduras argentina y chilena.

    Description: Body Matters approaches the material world directly; it seeks to remind people that they are the matter of their bodies. This volume offers an assortment of contributions from anthropology, archaeology and medieval studies, with case studies from northern Europe, the Near East, East Africa and Amazonia, which variously draw attention to the multiple shifting materials that comprise, impact upon and co-create human bodies. This lively collection foregrounds myriad material influences interacting with and shaping the human body; the chapters come together to illustrate the fundamental fleshy, bony, suppurating, leaky and oozing physicality of being human. Ultimately, by reminding readers of their indisputable materiality, Body Matters seeks to draw people and the rest of the material world together to illustrate that bodies not only seep into (and are part of) the landscape, but equally that people and the material world are inextricably co-constitutive.

    Description: Esta publicación surge como resultado de un itinerario de investigación, de reflexión y de debate colectivo que ya lleva varios años de compartida labor en torno a la problemática del Estado, los procesos políticos y la elaboración de políticas públicas. En el libro se desarrollan análisis teóricos y metodológicos sobre distintas aristas de la política pública: el papel de los saberes expertos, el análisis de las organizaciones estatales, la relación entre el Estado y los movimientos sociales, la participación ciudadana, el enfoque de género, la perspectiva del desarrollo, el gobierno abierto, las relaciones laborales y el trabajo en el sector público, entre otras cuestiones. La premisa básica de la que partimos es que la dinámica política y la dinámica estatal han de ser estudiadas conjuntamente, en sus vinculaciones, asincronías y mutua influencia. Esperamos que la lectura de estas páginas contribuya tanto a una mejor comprensión de las problemáticas actuales de las políticas públicas como a brindar sólida evidencia y productivos marcos analíticos para su abordaje.

    Description: Non-Intrusive Methodologies for Large Area Urban Research brings together contributions from a conference held in 2021 in association with the ERC-funded ‘Rome Transformed’ research project. The papers address a major challenge in archaeology. Non-intrusive research in pursuit of a deeper understanding of urban areas can be both richly informative and cost-effective. Multiple successes in the field have led to an impressive array of innovative methodologies, methodologies that are frequently combined for still greater insight and impact. Geophysical surveys, the use of UAVs, the study of exposed historic structures and the exhaustive examination of archival records can all play a vital role, and the development of these data capture methodologies is of the utmost importance for the future of research. As well as advances in data capture methodologies, however, the papers also present case studies in the management of the big data generated and in the integration of different methodologies. A further strength of this collection lies in the range of site types considered. While many projects have historically pursued non-intrusive research in areas relatively clear of modern buildings, a growing number of research initiatives, such as ‘Rome Transformed’ are seeking to advance them in areas which remain densely occupied. Accordingly the material presented here will also be of interest to non-archaeologists working in such diverse fields as civil engineering, urban planning and physical geography.

Esta investigación revisa las transformaciones políticas, económicas y eclesiales que dieron lugar a su surgimiento. A partir de estudiar de forma articulada los procesos históricos que implicaron la privatización de tierras fiscales y la expulsión de los campesinos que la usufructuaban; el deterioro de las economías regionales con epicentro en la producción algodonera, principal cultivo de la provincia; y la nueva sensibilidad asumida por sectores de la Iglesia Católica a favor de los sectores subalternos. Estos acontecimientos dieron marco a la conformación de espacios de sociabilidad que permitieron la formación de líderes rurales y estructuras organizativas que dieron origen a la entidad representativa del campesinado, rememorada como la experiencia de movilización social más importante en la historia provincial.

Esta frontera se presenta en este libro como una problemática de doble entrada: por una parte, frontera con el indio; por la otra, frontera entre territorios en construcción que disputan recursos y preminencias de gobierno sobre poblaciones móviles. El estudio se plantea desde el inicio de las primeras reformas borbónicas con la militarización del territorio e incluye los años clave de 1815 y 1820, durante los cuales ambos territorios se definen como provincias autónomas.

    Description: El Juicio a las Juntas Militares de 1985 fue un evento central en las políticas públicas que, desde la transición a la democracia en la Argentina, se implementaron para procesar las violaciones a los derechos humanos. Inauguró el escenario de los tribunales, desde entonces central en el tratamiento de las violaciones a los derechos humanos en el país, y ha jugado un papel medular en la conformación de representaciones, ideas y memorias sobre los crímenes del Estado dictatorial sucedidos cuatro décadas atrás. Sin embargo, fue mucho más que un evento jurídico. Se comportó también como un acontecimiento multidimensional, complejo, heterogéneo, en el cual múltiples actores actualizaron sus disputas sobre el sentido del pasado y el mundo político compartido. Este libro propone construir una genealogía de los usos y resignificaciones sociales del Juicio a las Juntas Militares, a partir de los discursos producidos tanto dentro como fuera de los tribunales y las memorias que el juicio suscitó desde su antesala hasta los años más recientes.

Se trata de una pesquisa realizada por el racionero Alfonso González que tiene por objeto dejar constancia escrita de los bienes y derechos que poseía el Cabildo al momento de su redacción. A través de la declaración de los testigos en los 118 lugares visitados es posible conocer la fisonomía y los contornos del dominio señorial, las modalidades de gestión del patrimonio, los mecanismos de acumulación y los procesos de diferenciación social, la estructura de la propiedad de la tierra, etc. Se constituye, por tanto, en una pieza clave para el conocimiento de la historia económico-social del espacio salmantino durante la Baja Edad Media.

    Description: Se puede reconstruir la situación general de la Argentina durante los años 1913-1923, pero menos estudiado ha sido el comportamiento de la crisis en las economías regionales dependiente del mercado interno. El presente libro intenta subsanar esa situación respecto de la vitivinicultura de Mendoza. Él recoge investigaciones inéditas y otras presentadas en reuniones científicas, publicadas en revistas especializadas o como capítulos de libros. El periodo elegido cubre el comienzo de la crisis del sector en 1913, la recuperación con el fin de la Gran Guerra, y los coletazos posteriores de la crisis hasta comienzos de 1923, cuando se derogó la legislación vitivinícola sancionada durante esos años.

    Description: As climate change becomes an increasingly important part of public discourse, the relationship between time in nature and history is changing. Nature can no longer be considered a slow and immobile background to human history, and the future can no longer be viewed as open and detached from the past. Times of History, Times of Nature engages with this historical shift in temporal sensibilities through a combination of detailed case studies and synthesizing efforts. Focusing on the history of knowledge, media theory, and environmental humanities, this volume explores the rich and nuanced notions of time and temporality that have emerged in response to climate change.

    Description: Fusion power may offer a long-term energy supply with an uninterrupted power delivery, a high power-generation density, and no greenhouse gas emissions, contributing to preventing the worst effects of climate change and making an enduring contribution to future energy supply. However, the intense conditions inside a fusion power plant (extreme temperatures and high magnetic fields necessary for nuclear fusion) call for addressing several potential problems. These include the development of new materials with extremely high heat tolerances and low enough vapor pressure and the design of mechanical structures that can withstand the electromagnetic force generated as well as feedback controllers to measure and counteract the unstable modes of evolution of the plasma, to name a few. The future of nuclear fusion as an efficient alternative energy source depends largely on techniques that enable us to control these instabilities. Mathematical modelling and physical experiments attempt to overcome some of the hindrances posed by these complexities.

    Description: El Apostadero Naval Malvinas, la Primera Unidad Naval creada en suelo malvinense el 2 de abril de 1982, fue un centro logístico de la guerra en el Atlántico Sur. Este libro reconstruye la historia del grupo Apostadero Naval Malvinas desde que sus integrantes regresaron al continente luego de la rendición en junio de 1982 hasta el año 2013, cuando se cumplieron 30 años de sus encuentros anuales, tomando como eje el clivaje experiencia-identidad-memoria. La investigación recoge las experiencias de posguerra de los civiles y militares que formaron parte del Apostadero, explorando las formas en que la vivencia bélica significó una marca en sus vidas, en sus identidades y sus memorias. A partir de allí, aborda las redefiniciones y modificaciones identitarias que atravesó este grupo de personas a lo largo de la posguerra, haciendo foco en las reuniones anuales del 20 de junio. Esto permite historizar la construcción de una memoria común de la guerra y de la propia experiencia bélica por parte de los miembros del grupo Apostadero.

    Description: Electromagnetic waves within a terahertz frequency range are becoming critical to investigating molecules, materials, and possible applications that are operated by both visible light and infrared rays. This book discusses sensing, imaging, and optoelectronic technologies of terahertz electromagnetic waves in theory and experiments. Most terahertz technologies can be explained by fundamentals of applied physics that have been demonstrated in other spectral ranges. However, the optoelectronic technology and corresponding configurations of imaging and sensing techniques are so special for various terahertz material polarization waves, which are excited in solid-state media by high-peak power lasers and waveguide transportation. Thus, this book also specifies terahertz parameters and available technologies.

From 2011 until 2014, Australia marked its long-standing connection with Antarctica by celebrating the centenary of the Australasian Antarctic Expedition. The icy continent, with its extremes of climate and environment and unique soundscapes, offers great potential for creative achievements in the world of music and sound. This book demonstrates the intellectual and creative engagement of artists, musicians, scientists and writers. Consciousness of sounds — in particular, musical ones — has not been at the forefront of our aims in polar endeavours, but listening to and appreciating them has been as important there as elsewhere.

    Description: In 1970 a small group of physicists at The Australian National University decided to veer away from the accepted and expected directions in energy research and pursued the emerging discipline of solar energy. Over the next decade ANU joined a small cluster of research institutions, including the CSIRO, UNSW and the University of Sydney, to emerge as a world leader in solar energy technology. This book traces the history of solar energy research at ANU over 35 years from its origin, its sometimes controversial early stages, through its flagship projects to its current status as one of the world's best known solar energy research establishments. It is as much a story of the future as it is a history: Following the sun is the story of how an idea to pursue what was in 1970 a new and unpopular research path has come to underpin sustainable development in the 21st Century.

    Description: The intermittent nature of solar energy sources is the greatest challenge to the broad acceptance of this technology. The storage of thermal energy presents a workable option for addressing this issue. When it comes to the storage of thermal energy, latent heat storage units (LHSU) that make use of phase change materials (PCMs) are more desirable than sensible heat storage. In the context of a large increase in the demand for energy, PCMs are an essential class of thermal energy storage materials that contribute to the sustainable growth of both the economy and society. It stores large amounts of heat in the form of latent heat at a constant temperature. This promising technique has already been applied with great success in a variety of applications like solar appliances, buildings, battery thermal management, electronic cooling, waste heat recovery systems, textiles, and more. This book presents an in-depth discussion on PCMs, the current state of PCM technology, and a detailed description of their prospective applications.

    Description: In a marine environment that is rapidly changing due to anthropogenic activities and climate change, area-based management tools are often used to mitigate threats and conserve biodiversity. Marine protected areas (MPAs) are amongst the most widespread and recognized marine conservation tools worldwide, however, MPAs alone are inadequate to address the environmental crisis. The promotion of other effective area-based conservation measures (OECMs) under draft Target 3 of the Post-2020 Global Biodiversity Framework, i.e., conserving 30% of marine areas by 2030, holds promise to acknowledge sites and practices occurring beyond MPAs that contribute to conservation. Here, we evaluate the potential recognition of OECMs into Indonesia's national policy framework on marine resource management and provide the first-ever overview of distribution and types of potential marine OECMs in Indonesia, including a review of the existing evidence on conservation effectiveness. We identified 〉 390 potential marine OECMs, led by government, customary and local communities, or the private sector, towards diverse management objectives, including habitat protection, traditional/customary management, fisheries, tourism, or other purposes. While some evidence exists regarding the conservation effectiveness of these practices, the long-term impacts on biodiversity of all potential marine OECMs in Indonesia are unknown. Many OECM elements have been included in several national policies, yet there are no established mechanisms to identify, recognize and report sites as OECMs in Indonesia. We propose four transformational strategies for future OECM recognition in Indonesia, namely: (i) safeguard customary and traditional communities, (ii) leverage cross-sector and cross-scale collaboration, (iii) focus on delivering outcomes, and (iv) streamline legal frameworks. Our study shows that OECMs have the potential to play a significant role in underpinning marine area-based conservation in Indonesia, including supporting the Government of Indonesia in reaching national and international conservation targets and goals.

    Description: While binaural technology applications gained in popularity in recent years, the majority of applications still use non-individual Head-Related Transfer Functions (HRTFs) from artificial heads. However, certain applications, for example research of spatial hearing or hearing attention, require an physically exact and realistic binaural signal. The limiting factor that prohibits the widespread use of individual HRTFs is the acquisition time of such data. This time requirement has recently been reduced by the use of parallelization in the measurement signal which lead to the development of fast measurement systems capable of acquiring individual and spatially dense HRTF. This thesis provides a objective and subjective evaluation of such a system that is designed with the goal of little disturbance of the measurements in mind. The construction is detailed, followed by both an objective and subjective evaluation. A detailed investigation into additional distortion of the sound field introduced by the system itself is presented and it is shown that the system performs comparably to a conventional system in terms of sound source localization. Furthermore, a method is introduced and evaluated to further reduce the measurement time by using continuous rotation during the measurement. This method is used to reduced the measurement duration from eight minutes to three minutes without audible differences.

    Description: Die Teilchenphysik als Teilgebiet der modernen Physik gewinnt zunehmend an Bedeutung im schulischen Physikunterricht. In dieser Arbeit wird erstmalig das von Lehrkräften benötigte Fachwissen zur Teilchenphysik modelliert, wobei Fachwissen als ein Teil des Professionswissens verstanden wird. Als Fachwissensdimensionen werden die Inhaltsbereiche und die Wissensarten in den Fokus genommen, für welche jeweils Subfacetten identifiziert und präzise beschrieben werden. Nach einem überblick über die wesentlichen Ideen der Teilchenphysik wird in der Arbeit die sukzessive Modellierung des Fachwissens im Rahmen einer qualitativ und quantitativ angelegten Delphi-Studie vorgestellt. In drei Befragungsrunden wurden zwischen 35 und 65 internationale Expertinnen und Experten aus der teilchenphysikbezogenen Forschung (Fachwissenschaft und Fachdidaktik) und öffentlichkeitsarbeit (u.a. Wissenschaftsjournalismus) sowie erfahrene Lehrkräfte zu den für das Fachwissen relevanten Themen der Teilchenphysik befragt. Empirische Analysen der Befragungsrunden ergaben, dass sich die Dimension Inhaltsbereiche im deklarativen Wissen aus zehn teilchenphysikalischen Themen (z.B. Teilchen in der Hochenergiephysik, die vier fundamentalen Wechselwirkungen) zusammensetzt, von welchen sechs als besonders relevant eingeschätzt wurden. Im Anschluss an die letzte Befragungsrunde wurde theoriegeleitet eine erste Modellierung der Inhaltsbereiche für die Wissensarten des prozeduralen und konditionalen Wissens vorgenommen.

    Description: Die in den vergangenen Jahren zahlreich entstandenen außerschulischen Lernorte an der deutschen Wattenmeerküste sind Ausdruck einer Differenzierung der dortigen Bildungslandschaft, in der schulisches durch non-formales Lernen im regionalen Kontext ergänzt wird. Die außerschulischen Lernorte zeichnet aus, dass sie ihren Besucherinnen und Besuchern Primärerfahrungen bieten, um die außergewöhnliche Dynamik und Sensitivität des Wattenmeeres zu verdeutlichen. Allerdings schöpfen die Lernorte ihr Potenzial für das außerschulische Physiklernen nicht aus, denn obwohl insbesondere Strömungen und Strukturbildungen (z. B. Rippel, Dünen und Priele) das Erscheinungsbild des Wattenmeers prägen und dessen Dynamik repräsentieren, werden in den Bildungsangeboten bisher fast ausschließlich biologische Inhalte behandelt. Deshalb ist physikdidaktische Forschungs- und Entwicklungsarbeit nötig, die durch eine Didaktische Rekonstruktion von Strömungen und Strukturbildungen geleistet wird. Hierzu gehört zunächst eine fachliche Klärung. Im Anschluss werden Lernendenvorstellungen untersucht, indem problemzentrierte Interviews entlang von Realexperimenten durchgeführt und einer qualitativen Inhaltsanalyse unterworfen werden. Auf Basis des Vergleichs zwischen fachlicher Sicht und Lernendensicht gilt es sodann, Bausteine für didaktische Strukturierungen zu entwickeln. Diese Bausteine werden schließlich eingesetzt, um gemeinsam mit den Lernortbetreibenden Bildungsangebote zu entwickeln, die auch physikalische Zusammenhänge zur Küstendynamik explizieren.

    Description: Problemlösen ist eine wesentliche Voraussetzung für das Handeln in allen Bereichen des Lebens: In einfachen Alltagssituationen, bei (natur-) wissenschaftlichen Fragestellungen oder bei komplexeren gesellschaftlich relevanten Problemen spielt die Lösung von Problemen eine Rolle. Im Bereich der Physik werden insbesondere innerhalb des schulischen und universitären Kontextes Probleme bearbeitet. Die täglichen Erfahrungen des Lehrbetriebs an Hochschulen machen jedoch deutlich, dass Teile der Studierenden große Schwierigkeiten haben, Probleme erfolgreich zu lösen. Die Diskrepanz zwischen der Wichtigkeit des Problemlösens und den Schwierigkeiten, die Studierenden dabei haben, ist der Ausgangspunkt für die zentrale Fragestellung der vorliegenden Arbeit: Was unterscheidet "gute" von "schlechten" Problemlösern und welche Faktoren beeinflussen den Erfolg beim Problemlösen? Die Arbeit fokussiert hierbei auf Probleme aus dem Themenfeld der Mechanik. Mit Hilfe einer empirischen Untersuchung wird dazu beigetragen, bereits bekannte Erkenntnisse aus der traditionsreichen Forschung zum Problemlösen zu bestätigen, zu quantifizieren und zueinander in Beziehung zu setzen. Es werden sowohl quantitative als auch qualitative Eigenschaften "guter" und "schlechter" Problemlöser herausgearbeitet - gute Problemlöser können beispielsweise auf mehr Fachwissen zurückgreifen, besitzen ein höheres Selbstkonzept und machen weniger Planungsfehler beim Bearbeiten physikalischer Problemstellungen.

    Description: Our world today is becoming increasingly complex, and technical devices are getting ever smaller and more powerful. The high density of electronic components together with high clock frequencies leads to unwanted side-effects like crosstalk, delayed signals and substrate noise, which are no longer negligible in chip design and can only insufficiently be represented by simple lumped circuit models. As a result, different physical phenomena have to be taken into consideration since they have an increasing influence on the signal propagation in integrated circuits. Computer-based simulation methods play thereby a key role. The modelling and analysis of complex multi-physics problems typically leads to coupled systems of partial differential equations and differential-algebraic equations (DAEs). Dynamic iteration and model order reduction are two numerical tools for efficient and fast simulation of coupled systems. Formodelling of low frequency electromagnetic field, we use magneto-quasistatic (MQS) systems which can be considered as an approximation to Maxwells equations. A spatial discretization by using the finite element method leads to a DAE system. We analyze the structural and physical properties of this system and develop passivity-preserving model reduction methods. A special block structure of the MQS model is exploited to to improve the performance of the model reduction algorithms.

    Description: Experimentieren kann nicht nur dazu beitragen, fachinhaltliche Erkenntnisse zu gewinnen, sondern auch selbst Lerngegenstand sein. Wenig geklärt ist bisher, wie beim Experimentieren gelernt wird, worauf zu achten ist. Unklar ist auch, welche fachmethodischen Vorstellungen Lernende beim Planen, Durchführen und Auswerten aktivieren. Diesen Fragen wurde mithilfe einer schriftlichen Instruktion nachgegangen, die Lernende (Jg. 11) anregt, nicht nur Experimente durchzuführen, sondern auch über fachmethodische Grundlagen nachzudenken. Die Arbeitsphasen wurden für 42 Schülergruppen videografiert und kategorienbasiert ausgewertet, um Aussagen über Aktivitätsprofile, Vorstellungen und Kompetenzveränderungen zu generieren. Die Ergebnisse belegen die Komplexität von Lernprozessen und zeigen die Schwierigkeit, individuelle Kompetenzzuwächse auf bestimmte Prozesse zurückzuführen. Zum Beispiel konnten hohe Kompetenzzuwächse sowohl für Lernende mit häufigen fachmethodischen Beiträgen als auch für solche mit nur geringen fachmethodischen Aktivitäten festgestellt werden. Des Weiteren gehen experimentell angemessene Aktivitäten in erkennbaren Anteilen mit fachmethodisch unpassenden Vorstellungen einher, wie z.,B. bei einer korrekt vorgenommenen, aber falsch begründeten Trennung zwischen einer Beobachtung und einer Deutung. Die Arbeit liefert damit Hinweise, dass Lernende neben fachinhaltlichen auch fachmethodische Vorstellungen in den Unterricht mitbringen. Diese gilt es z.,B. durch explizite und wiederholte Thematisierung zu adressieren.

    Description: In einem Solarturmkraftwerk werden hunderte bis tausende Spiegel (sogenannte Heliostate) einzeln der Sonne nachgeführt, sodass das Sonnenlicht auf die Spitze eines Turmes konzentriert wird. Dort befindet sich der Receiver, der die Solarstrahlung absorbiert und an das Wärmeträgermedium weitergibt. Große thermische Energiespeicher erlauben die ganztägige Stromproduktion (auch Nachts). In aktuellen Solarturmkraftwerken kommen als Wärmeträger- und Speichermedium häufig flüssige Nitratsalze wie Solar Salt zum Einsatz. Aufgrund ihrer hohen Wärmekapazität und den geringen Kosten eignen sie sich sehr gut zur thermischen Energiespeicherung, jedoch bringen sie auch einige Nachteile mit sich. Flüssigmetalle weisen in vielen Punkten Vorteile gegenüber den Flüssigsalzen auf. In der vorliegenden Arbeit werden die Eigenschaften von Flüssigmetallen detailliert analysiert und mit Solar Salt verglichen. Zur Bewertung werden die Jahreserträge bzw. die Stromgestehungskosten (LCOE) herangezogen. Die Ergebnisse zeigen ein Potenzial zur Reduktion der Stromgestehungskosten mit Flüssigmetallen um bis zu 16 % gegenüber dem Referenzsystem mit Solar Salt, ohne dabei den Kraftwerksblock und den thermischen Speicher zu verändern.

    Description: In 2005, the hybrid model was published by Prof. H.-D. Alber and Prof. P. Zhu as an alternative to the Allen-Cahn model for the description of phase field transformations. With low interfacial energy, it is more efficient, since the resolution of the diffuse interface is numerically broader for the same solution accuracy and allows coarser meshing. The solutions of both models are associated with energy minimisation and in this work the error terms introduced in the earlier publications are discussed and documented using one and two dimensional numerical simulations. In the last part of this book, phase field problems, initially not coupled with material equations, are combined with linear elasticity and, after simple introductory examples, a growing martensitic inclusion is simulated and compared with literature data. In addition to the confirmed numerical advantage, another phenomenon not previously described in the literature is found: with the hybrid model, in contrast to the examples calculated with the Allen-Cahn model, an inclusion driven mainly by curvature energy does not disappear completely. The opposite problem prevents inclusions from growing from very small initial configurations, but this fact can be remedied by a very finely chosen diffuse interface width and by analysing and adjusting the terms that generate the modelling errors. The last example shows that the hybrid model can be used with numerical advantages despite the above mentioned peculiarities.

    Description: Ein zentrales Ziel der fachdidaktischen Forschung stellt die Verbesserung schulischen Unterrichts dar. Eine Transferstrategie zur flächendeckenden Verbreitung wissenschaftlicher Erkenntnisse bildet die Bereitstellung evidenzbasierter, innovativer materialgestützter Unterrichtskonzeptionen. Allerdings fällt das Materialnutzungsverhalten von Lehrkräften individuell sehr unterschiedlich aus, wobei das Zusammenspiel verschiedener Einflussfaktoren auf die Materialnutzung bislang wenig erforscht ist. Ziel der vorliegenden Arbeit ist es daher, dieses Wirkgefüge unter authentischen Bedingungen genauer zu untersuchen. Dazu wurde kriteriengeleitet eine evidenzbasierte, fachdidaktisch innovative Unterrichtskonzeption ausgewählt (das Münchener Unterrichtskonzept zur Quantenmechanik) und den teilnehmenden Lehrkräften fakultativ zur Verfügung gestellt. Mittels eines qualitativen Forschungsansatzes wurden elf Lehrkräfte bei der Implementierung des Konzepts durch ein Interview zu Beginn und am Ende einer Unterrichtsreihe zur Quantenmechanik sowie zwei Unterrichtsbeobachtungen mit je einem anschließenden stimulated recall begleitet. Aus den Ergebnissen folgt, dass die Probanden sich überwiegend heuristisch mit der Konzeption auseinandersetzten und lediglich Elemente auf Sichtstrukturebene implementierten. Das nachgewiesene Wirksamkeitspotential von evidenzbasierten, innovativen Unterrichtskonzeptionen scheint sich folglich lediglich unter bestimmten Bedingungsfaktoren zu entfalten.

    Description: Die vorliegende Dissertation beschreibt den Entwicklungs- und Validierungsprozess eines neuen Testinstruments zur Erfassung von Lehrer-Selbstwirksamkeitserwartungen in vier physikdidaktischen Handlungsfeldern (Umgang mit Aufgaben, Experimentieren, Elementarisieren, Umgang mit Schülervorstellungen), jeweils bezüglich der Dimensionen Planung und Durchführung von Physikunterricht. Die Instrumententwicklung erfolgt in hohem Maße theoriebasiert, indem unter anderem auf der Grundlage der sozial-kognitiven Theorie Banduras Regeln für die Itemkonstruktion abgeleitet werden, die außerdem eine kritische Analyse existierender Instrumente erlauben. Der mehrschrittige Validierungsprozess ist argumentbasiert angelegt. Im Rahmen einer Interviewstudie und einer Expertenbefragung werden vor allem inhaltliche Aspekte, wie z.B. die definitionskonforme Formulierung der Items, die Abdeckung des Handlungsfeldes oder die wahrgenommene Authentizität der Items, untersucht. Im Zuge der auf eine quantitative Auswertung angelegten Hauptstudie (N approx 1000) werden vor allem psychometrische Aspekte, wie die Eindimensionalität der Skalen oder die Passung des Antwortformates, in den Blick genommen. Zusammenfassend kann ein übergeordnetes Validitätsargument in Bezug auf die intendierte Testwertinterpretation formuliert werden. Weiterer Forschungsbedarf deutet sich unter anderem bezüglich der Unterscheidung der zwei genannten Dimensionen an.

    Description: In Lehr-Lern-Labor Seminaren können Lehramtsstudierende ihr fachliches, didaktisches und pädagogisches Wissen aufgreifen und in komplexitätsreduzierten Handlungsumgebungen anwenden. Dabei erstellen sie Experimentierstationen, um anschließend in einer iterativen Praxis mehrmals Schülerinnen und Schüler an diesen Stationen zu betreuen. Grundlegend für dieses Vorgehen sind Reflexionsprozesse zwischen den Betreuungen. Inwieweit diese Reflexionsprozesse die Entwicklung der Professionellen Unterrichtswahrnehmung der Studierenden fördern, wurde mit dieser Arbeit untersucht. Als ergänzende Intervention wurden fragenbasierte Videoanalysen der eigenen Betreuungen in das Seminar implementiert. Die Regressionsanalysen zeigten, dass sich die Professionelle Unterrichtswahrnehmung der Studierenden durch die Teilnahme am Seminar verbesserte, wenn zusätzlich das eigene Vorgehen und das ihrer Kommilitonen anhand der erstellten Videos analysiert wurden. Ohne Videoanalyse konnte keine Veränderung festgestellt werden.

    Description: Bei Schülerlaboren als wichtigem Teil außerschulischer MINT-Bildung besteht ein Forschungsdefizit hinsichtlich kognitiver und motivationaler Prozesse auf Seiten der Schülerinnen und Schüler. Mit einem Design-based Research Ansatz klärt die Studie deshalb die Dynamik der Lehr- und Lernprozesse in Schülerlaboren auf und erlaubt es, die Lernangebote mit Blick auf generelle Bildungsziele und spezifische Ziele der Labore empiriebasiert weiterzuentwickeln. Um Angebots-Nutzungs-Prozesse zu untersuchen, wird ein Analyseinstrument entwickelt; es erlaubt gleichermaßen, die didaktische Struktur der Angebote in einer SWOT-Analyse zu erfassen und die ablaufenden Denk- und Lernprozesse der Schülerinnen und Schüler empirisch zu erheben. Das Instrument fokussiert auf drei Dimensionen: die Orientierung der Angebote an Kontexten, die Integration von Problemlöseaufgaben und die Unterstützung von Autonomie der Schülerinnen und Schüler beim Entscheiden und Handeln. Die Ergebnisse der SWOT-Analyse werden mit empirischen Daten, die mit ethnografischen Methoden gewonnen werden, validiert. Eine daraufhin weiterentwickelte didaktische Struktur der Angebote ist hinsichtlich einer differenzierten Kontextualisierung, des Einsatzes narrativer Anker, die Problemlöseaufgaben einleiten, sowie einer phasenweisen Öffnung der Angebote verändert und führt zu besserem Verständnis fachlicher Inhalte und zu einer höheren Motivation.

    Description: Die professionelle Unterrichtswahrnehmung ist eine zentrale und situative Fähigkeit, die (angehende) Lehrkräfte befähigt, Lernprozesse im Unterricht zu erkennen, mithilfe ihres professionellen Wissens zu interpretieren und anschließend lernförderliche Handlungspläne abzuleiten. Der vorliegenden Arbeit liegt die Forschungsfrage zugrunde, ob diese Fähigkeit mit einem physikspezifischen Fokus mithilfe eines Instruments - bestehend aus inszenierten Unterrichtsvideos und einem teilweise geschlossenen Fragebogen - valide erfasst werden kann. Ein solches Instrument könnte dazu dienen, herauszufinden, ob die professionelle Unterrichtswahrnehmung domänenspezifisch ist (Hypothese 1) und ob diese situative Fähigkeit entlang der universitären Ausbildung eine Progression erfährt (Hypothese 2).  Die Ergebnisse der Arbeit ergeben 19 Items (EAP Reliabilität liegt bei 0.698), mit denen eine physikspezifische professionelle Unterrichtswahrnehmung gemessen werden kann. Weitere Analysen (zur Korrelation mit dem physikdidaktischen Wissen und der Abhängigkeit von studiumsbezogenen Daten) stützen die Konstruktvalidität des Tests. In Bezug auf Hypothese 1 hat sich wie erwartet gezeigt, dass die physikspezifische professionelle Unterrichtswahrnehmung signifikant von dem studierten Fach und dem Studiengang abhängt. Anders als erwartet ergeben die Ergebnisse zur Hypothese 2, dass die professionelle Unterrichtswahrnehmung aber nicht signifikant vom Studienfortschritt abhängt.

    Description: Erkenntnisgewinnung ist in den Naturwissenschaften untrennbar mit wissenschaftlichen Kontroversen verknüpft, die auch für den Physikunterricht einen Bildungswert besitzen, insbesondere im Hinblick auf kritische Urteilsbildung, Multiperspektivität und ein angemessenes Nature-of-Science-Verständnis. Basierend auf einer Charakterisierung wissenschaftlicher Kontroversen wird am Beispiel der Frage nach der Relativität der Masse in der Speziellen Relativitätstheorie in einer explorativ-qualitativen Studie untersucht, wie Physiklehrkräfte und Physiklehramtsstudierende mit einer solchen Kontroverse umgehen und inwieweit sie deren Bildungswert nutzen. Dazu werden sowohl Gedankenauflistungen, die von den Befragten nach dem Lesen von Textmaterialien zu den unterschiedlichen Fachpositionen erstellt wurden, als auch Antworten zu verschiedenen Textvignetten mit Hilfe der qualitativen Inhaltsanalyse ausgewertet. Insgesamt zeigt sich, dass die Studierenden häufiger offen gegenüber den kontroversen fachwissenschaftlichen Positionen sind als die Lehrkräfte. Unterschiede in Bezug auf die Realisierung des Bildungswertes im Unterrichtskontext werden mithilfe von fünf Typen systematisch beschrieben. Ein Großteil der Befragten weist dabei Ansätze zur Umsetzung von Kontroversität im Physikunterricht auf. Die Mehrheit vertritt auch eine eigene fachwissenschaftliche Position und ein Teil der Befragten nutzt die wissenschaftliche Kontroverse zur Thematisierung von Nature-of-Science-Aspekten.

    Description: Fachdidaktisches Wissen gilt als wichtige Gelingensbedingung für einen professionell durchgeführten Unterricht. Positive Selbstwirksamkeitserwartungen, vielfältige Unterrichtskompetenzen sowie eine befürwortende Einstellung gegenüber der Reflexion von Unterricht sind darüber hinaus Indikatoren einer gelingenden Professionalisierung. Professionelle Handlungskompetenz entwickelt sich vornehmlich, wenn angehende Lehrkräfte die Gelegenheit bekommen theoretische Wissensanteile in der Praxis umzusetzen und diesen Transfer zu reflektieren. Die unreflektierte Absolvierung von Unterrichtspraktika birgt nämlich die Gefahr eines "Praxisschocks". Um dem vorzubeugen, ist es förderlich, praktische Studienanteile in ihrer Komplexität sukzessive zu steigern. Es wird davon ausgegangen, dass Lehr-Lern-Labore (LLL) diesen Anforderungen genügen. In der vorliegenden Arbeit wurde die professionalisierende Wirkung dieses Veranstaltungskonzepts am Beispiel des LLL "Schwimmen, Schweben, Sinken" multimethodisch untersucht. Dabei wurden Gruppendiskussionen und Interviews, eine hoch inferente Fremdeinschätzungserhebung sowie eine Prä-Post-Fragebogenstudie mit Studierenden der Bachelorstudiengänge Lehramt Physik sowie Grundschulpädagogik (Sachunterricht) an der Freien Universität Berlin durchgeführt. Die Ergebnisse zeigen, dass Lehr-Lern-Labor-Veranstaltungen einen wichtigen Beitrag zur Anbahnung sowie zur Unterstützung der Professionalisierung von Lehrkräften bereits während des Studiums leisten können, ohne dass es zum "Praxisschock" kommt.

    Description: Eine lernendenorientierte und adaptive Gestaltung von Unterricht erfordert von den Lehrkräften, dass sie vorhandene Kompetenzen und Lernprozesse der Schülerinnen und Schüler diagnostizieren. Außerdem müssen sie die Anforderungen von Aufgaben mit Blick auf deren Passung zu den Lernprozessen der Schülerinnen und Schüler analysieren können. Eine derart verstandene "diagnostische Kompetenz" wird als zentrales Professionalisierungsziel von Lehrkräften angesehen. Vor diesem Hintergrund wurden die diagnostischen Prozesse von acht Studierenden mit den Fächern Physik und Mathematik in zwei aufeinander folgenden Lehrveranstaltungen zur Diagnostik untersucht, um Potentiale und Lernhindernisse im Kompetenzaufbau zu identifizieren. In beiden Veranstaltungen bildeten Vignetten von Lernprozessen den Ausgangspunkt für studentische Diagnosen. Forschungsgegenstand waren u.a. schriftliche Diagnosen der Studierenden im Prä-Post-Vergleich sowie auf Video aufgezeichnete studentische Diskurse bei der Diagnose von Lernprozessen der Schülerinnen und Schüler. Die Analysen erfassen u.a., auf welche Komponenten eines Diagnoseprozesses die Studierenden in welcher Weise Bezug nehmen und welche (fach-) didaktischen überlegungen bzw. Theoriebezüge sie in ihren Diagnosen als Referenzpunkte nutzen. Die Ergebnisse zeigen, dass auf struktureller Ebene zwar alle Komponenten thematisiert, aber inhaltlich nicht entlang einer typischen Abfolge miteinander verbunden werden. Trotz inhaltlicher Prompts wird nur selten explizit auf Theoriebezüge zurückgegriffen.

    Description: The main focus of this thesis is the discussion of stability of an objective (atomic) structure consisting of single atoms which interact via a potential. We define atomistic stability using a second derivative test. More precisely, atomistic stability is equivalent to a vanishing first derivative of the configurational energy (at the corresponding point) and the coerciveness of the second derivative of the configurational energy with respect to an appropriate semi-norm. Atomistic stability of a lattice is well understood, see, e.,g., [40]. The aim of this thesis is to generalize the theory to objective structures. In particular, we first investigate discrete subgroups of the Euclidean group, then define an appropriate seminorm and the atomistic stability for a given objective structure, and finally provide an efficient algorithm to check its atomistic stability. The algorithm particularly checks the validity of the Cauchy-Born rule for objective structures. To illustrate our results, we prove numerically the stability of a carbon nanotube by applying the algorithm.

    Description: Die Optimierung dynamischer Dichtsysteme ist eine kostengünstige Methode zur Erhöhung der Wirkungsgrade, Lebensdauer und Betriebssicherheit von Turbomaschinen. Zuverlässige und effiziente Dichtsysteme lassen sich nur realisieren, wenn die Anstreifvorgänge zwischen rotierenden und statischen Komponenten sowie ihre Folgen schon bei der Auslegung berücksichtigt und im Betrieb beherrscht werden können. Bis heute sind die physikalischen Vorgänge beim Anstreifen jedoch nur unzureichend verstanden und es fehlen zuverlässige Modellierungsansätze für ihre Vorhersage. Die vorliegende Arbeit liefert einen essentiellen Beitrag zum Verständnis des Anstreifverhaltens und somit zur Optimierung einlaufender dynamischer Dichtsysteme mit Fokus auf Labyrinthdichtungen mit Einlaufbelägen aus Hohlkörperstrukturen. Mit Hilfe aufwändiger experimenteller Untersuchungen wird in dieser Arbeit ein tiefergreifendes physikalisches Verständnis der Anstreifvorgänge bereitgestellt. Die experimentell gewonnenen Erkenntnisse bilden schließlich die Grundlage für die Entwicklung eines Modellierungsansatzes, der erstmals unter Berücksichtigung aller Einflussparameter die zuverlässige Vorhersage des Anstreifverhaltens einlaufender Labyrinthdichtungen ermöglicht.

    Description: Formeln sind eine wichtige mathematische Darstellungsform im Physikunterricht. Jedoch haben Lernende häufig Schwierigkeiten bei der Verbalisierung der inhaltlichen Bedeutung von Formeln. Dies wirft die Frage auf, wie Lehrende diese inhaltliche Seite von Formeln vermitteln. Der Theorieteil stellt den Empiriestand zu den Themenkomplexen Formeln und Kommunikation, Alltagssprache, Unterrichts -sprache und Fachsprache im Physikunterricht ausführlich dar. Auf Grundlage sprachwissenschaftlicher Überlegungen wurde ein Ebenenmodell der Versprachlichung von Formeln entwickelt und durch Lehrbuchanalysen validiert, mit dessen Hilfe das Sprechen von und über Formeln analysiert werden kann. In einer qualitativen, explorativ ausgerichteten Feldstudie wurde Physikunterricht von 10 Lehrenden zum elektrischen Widerstand beobachtet und ihre Sprache mit Hilfe der qualitativen Inhaltsanalyse und des entwickelten Ebenenmodells ausgewertet. Das entstandene Kategoriensystem zeigt ein vielfältiges Sprechen über Formeln, das viele Aspekte von Formelverständnis abdeckt. Eine explizite qualitative Interpretation von Formeln bleibt jedoch meist aus. Es zeigt sich in vielen Aspekten ein eher technischer Umgang mit Formeln, der die strukturelle Rolle der Mathematik vernachlässigt. Das Sprechen der Lehrenden im Umgang mit Formeln kann als entweder fachsprachlich, schülernah oder ausgewogen, in einigen Fällen zusätzlich als reflektierend charakterisiert werden.

    Description: Die fortschreitende Digitalisierung erleichtert den Einsatz von computergestützten Experimentiergelegenheiten in Schule und Universität. Dabei ermöglichen solche Experimente Lernenden eigenständige Erfahrungen mit neuen Fachinhalten. Im Rahmen der vorliegenden Arbeit wurde ein lernerzentriertes und webbasiertes Angebot entwickelt, mit dem Lernende selbstständig Experimente zur Elektronenbewegung in Feldern durchführen können. Dabei wurden verschiedene Möglichkeiten zur Unterstützung der Lernprozesse, die der Einsatz digitaler Endgeräte mit sich bringt, realisiert - dies sind u.a. der Einsatz von Augmented Reality, ergänzenden Visualisierungen und automatisiertem Feedback. Doch über die Häufigkeit und die Art der Nutzung entsprechender Angebote in Schule und beim selbstständigen Lernen gibt es bisher nur wenige empirisch abgesicherte Erkenntnisse. Daher wurde hierzu eine Nutzungsanalyse mithilfe von Usertracking durchgeführt. Diese zeigt, dass das Angebot sowohl im Unterricht als auch beim selbstständigen Lernen sehr häufig genutzt wird, und deckt auf, welche Elemente zu einer intensiven Nutzung des Angebotes führen. Weiter wurde in einer Laborstudie die Wirkung von Multiplen Repräsentationen auf den Erfolg beim experimentellen Hypothesenprüfen und den wahrgenommenen Cognitive Load untersucht. Hier zeigte sich, dass integrierte, dynamisch verlinkte Repräsentationen die Nutzer unterstützen, aber keinen zusätzlichen Cognitive Load verursachen. Dies sollte bei der Gestaltung zukünftiger Angebote berücksichtigt werden.
