Abstract

Die Schabkunst, aufgrund ihrer besonderen Blüte im englischen 18. Jahrhundert zur Zeit der Personalunion hannoverscher Herzogs- und britischer Königswürde auch „Englische Manier“ genannt, ist die erste grafische Technik, in der über Linie und Schraffur hinaus flächige Tonwerte und Tonwertabstufungen geschaffen werden konnten. Malerische Werte ließen sich erzeugen und malerische Werke nachbilden. Anders als in den liniengebundenen Techniken des Kupferstichs und der Radierung ermöglichten mechanische Aufrauhung und deren dosierte Glättung Töne von samtigem Schwarz bis zu reinem Weiß. Erfindung und Perfektionierung, Nutzung und Verbreitung, Traditionsbildung und Experimentalpotential dieser druckgrafischen Technik können anhand der Schabkunstwerke der Grafischen Sammlung der Universität Göttingen und einiger Leihgaben vorgeführt werden: 105 Werke demonstrieren erste Experimente deutscher und niederländischer Laien und Künstler, technische Perfektionierungen in den druckgrafischen Zentren Augsburg und Nürnberg, Adaptionen in Frankreich und Italien, Verselbständigung des Mediums in England und experimentelle Verwendung als künstlerisches Ausdrucksmittel in der deutschen Frühmoderne. Funktionsgebundene Nutzung als Medium der Gemäldereproduktion und lebensnahen Bildniskunst, und erstmals als Naturnähe ermöglichendes Dokumentationsmittel in den frühneuzeitlichen Naturwissenschaften werden thematisiert.

Abstract

Wealth and power characterize elites, yet despite the strong cultural influences they exert, their study remains underdeveloped. Partly because of complications resulting from access, scholars have tended to focus on groups affected by elite governance rather than on elites themselves. It is often overlooked that, in order to continue through time, elites have to empower new members. Choice has to be exercised over who achieves leadership, both by reference to the elite group itself and to the wider group over which it holds power. This book fills a gap in the current literature by providing the first rigorous interrogation of the choice and succession strategies of elites in various cultural contexts - from the transmission and preservation of financial power in urban contexts to the complex relation between subjectivity and the transmission of leadership positions in places as varied as the United States, Northern Italy and Lisbon. Various elite succession types are discussed, from self-avowedly 'traditional' leaders to the aristocracy, where choice is practically non-existent, to situations where leaders are elected from amongst a group of peers. The relationship between familial property and choice of successor in landholding families, small business enterprises, and peasant communities is also examined, as are ethnic monopolies.

Abstract

Dans un contexte de profond renouvellement historiographique de l’étude du pouvoir depuis une quinzaine d’années, dix-huit historiens et chercheurs tant français qu’étrangers (anglais, portugais et espagnols) ont confronté leur vision de l’histoire sociale du politique en étudiant, du milieu du XVIe siècle à la veille de la Première Guerre mondiale, les élites dirigeantes urbaines des principaux pays d’Europe occidentale et de leurs possessions coloniales dans le Nouveau-Monde. Les études réunies ici abordent le sujet sous des angles variés mais complémentaires : présentation d’individus et de lignages qui ont pu symboliser en leur temps un parcours politique hors du commun, études sociales et familiales des élites dirigeantes de quelques grandes villes, études comparatives à l’échelle d’une région, entre une métropole et ses possessions ultramarines, voire entre plusieurs pays. Modalité d‘accès au pouvoir, réseaux familiaux, importance des dynasties, relations avec le pouvoir central, spécificité ou non des villes portuaires ont été au cœur des problématiques des auteurs. L’ensemble est découpé en quatre grands thèmes : familles et pouvoirs dans le monde atlantique, opposition entre villes portuaires et villes de l’intérieur, pouvoir et réseaux dans les villes continentales, destins individuels et destins collectifs.

Abstract

The volume aims at a comprehensive historical reconstruction of policies, conflicts, attitudes, and regulations covering the diverse field of human reproduction. The analysis is based on two case studies: the United States of America and Austria. While both countries are part of the geographic and conceptual region called the "north-Atlantic world", they occupy significantly different positions within the global power structure, the respective relations between state, religion and society, the nature of their political cultures, etc. While it is impossible to re-construct a universal history of population policies on the basis of the two case studies, in the concluding chapter more universal premises relating to 20th century trends and developments beyond the case studies are suggested. To enable a comprehensive, yet focused comparison the analysis concentrates on three aspects of reproductive policies: sexual advice centers in the cities of New York and Vienna during the interwar period; 20th century policies aimed at the interface between workplace and child care; and the abortion conflicts taking place in the last third of the 20th century. These fields are conceptualized as "arenas"—i. e., spaces or complex social situations where groups and individuals interested in a given issue meet and interact, attempt to establish their world views, and then transform them into commonly accepted norms and regulations. Events, actors, and developments are thoroughly re-constructed for each arena. Finally the arenas are analyzed in relation to social and political developments in which they are situated. Questions about trends and developments relevant for both case studies are addressed in a framework which is organized around notions of reproduction of the nation, of rationalization, and of globalization. The findings from the case studies are related to secular phenomena like migration, globalizing selective population policies, the emergence of international and transnational political bodies (private foundations, UN-organizations, NGOs). The comparison between the U.S. and Austria offers insights into the tensions inherent in modern reproduction between individual empowerment and political disciplining. The striking similarities and significant differences in the trajectories of reproductive policies in both case studies allow conclusions concerning an indissoluble dilemma of reproductive policies committed to "human progress." In the end, the volume contributes to a deeper understanding of the ambivalence inherent to modern reproduction.

Abstract

Anti-social behaviors and social deficits induced mental disorders are critical problems in our society today. Social behaviors and interactions are shaped by experience, hereditary components (genes, hormones and neuropeptides) and environmental factors (photoperiods and metabolic signals). In addition to the classical gonadotropin-releasing hormone, RFamide peptides, kisspeptin and gonadotropin-inhibiting hormone are emerging as important regulators of the reproductive axis. These neuropeptides are evolutionarily conserved and are regulated by environmental factors. In this Research Topic, we advocate more recent advances in reproductive neuropeptides and sex steroids in the domains of social behavior including sexual and parental behavior, aggression, stress and anxiety. Using multiple species model, we also review how genes and the neuroendocrine system interact at the cell and organismic levels to contribute to social behavior in particular the epigenetic genomic changes caused by early life environment. We provide comprehensive insights of distinct neural networks and how cellular and molecular events in the brain regulate social behavior from a comparative perspective.

Abstract

The phenotype of a plant in response to a stress condition is the reflection of the molecular responses in different cell-types composing the plant. The multicellular complexity represents a challenge when accessing specific responses of each cell or cell type composing the plant. To overcome this difficulty and allow the clear characterization of the plant cell molecular mechanisms, the research community is now focusing on studying a single cell and single cell-types. The isolation of plant single cells is limited by the cell wall that confers the rigidity of the plant and its overall structure. Various methods have been developed for isolating plant cells (e.g. laser capture microdissection; cell sorting of Green Fluorescent Protein (GFP)-tagged protoplasts, differential protoplastization of cells such as guard cells, isolation of easily accessible cell types such as cotton fiber, pollen cells, trichomes and root hair cells). The development of these innovative approaches to isolate single plant cells or cell-types combined with the application of sensitive and high-throughput technologies allows a better analysis of the developmental processes and response to environmental stresses. Ultimately, single plant cell and cell-type biology will lead to establishment of more reliable and accurate -molecular regulatory networks at the resolution of basic life unit. The goal of this Research Topic is to cover new technological and biological advances in the study of plant single cell, cell-type and systems biology.

Abstract

Understanding the factors that create and maintain social inequalities is a core question in social psychology. Research has so far mainly focused on the role of individual stereotyping, prejudice and discrimination. However, there is growing evidence that, beyond the “biased” acts of prejudiced individuals, structural factors related to the very functioning of institutions and organizations can play a role in the reproduction of social inequalities. Indeed, in industrialized countries, society is structured in a way that reflects the perspective of, is organized by, and benefits the dominant groups. In this Research Topic, we propose to bring together researchers who study how institutional ideologies and practices promote norms, rules and opportunities that favor dominant groups and disadvantage dominated groups. This question can be tackled by work investigating how institutional practices (e.g., grading, tracking, recruitment, …) and ideologies (e.g., meritocracy, individualism, protestant work ethic, …) shape the psychological experience of (dis)advantaged people. Moreover, another interesting venue is represented by work investigating how the institutional practices and ideologies are enacted by the agents (e.g., teachers, recruiters, leaders, …). Taking the perspective of agents allows to investigate how institutional functioning constrains the actual opportunities they provide to (dis)advantaged individuals. This could also highlight how institutional ideologies and practices are incorporated by agents, thus revealing mechanisms of change vs. perpetuation of the institutional functioning.

Abstract

Neuroendocrinology is the discipline that investigates the interplay between the nervous and endocrine systems i.e. the control of endocrine glands by the central and peripheral nervous systems, the action of hormones on nerve cells and the production of hormones by the nervous system. The present Research Topic is a compilation of contributions stemming from the 8th International Congress of Neuroendocrinology (ICN2014) held in Sydney, Australia, that illustrates various facets of current neuroendocrine research.
