AbstractIn recent years, biologists and philosophers of science have argued that evolutionary theory should incorporate more seriously the idea of ‘reciprocal causation.’ This notion refers to feedback loops whereby organisms change their experiences of the environment or alter the physical properties of their surroundings. In these loops, in particular niche constructing activities are central, since they may alter selection pressures acting on organisms, and thus affect their evolutionary trajectories. This paper discusses long-standing problems that emerge when studying such reciprocal causal processes between organisms and environments. By comparing past approaches to reciprocal causation from the early twentieth century with contemporary ones in niche construction theory, we identify two central reoccurring problems: All of these approaches have not been able to provide a conceptual framework that allows (i) maintaining meaningful boundaries between organisms and environments, instead of merging the two, and (ii) integrating experiential and physical kinds of reciprocal causation. By building on case studies of niche construction research, we provide a model that is able to solve these two problems. It allows distinguishing between mutually interacting organisms and environments in complex scenarios, as well as integrating various forms of experiential and physical niche construction.

Abstract. It is increasingly acknowledged that, in order to sustainably manage global freshwater resources, it is critical that we better understand the nature of human–hydrology interactions at the broader catchment system scale. Yet to date, a generic conceptual framework for building models of catchment systems that include adequate representation of socioeconomic systems – and the dynamic feedbacks between human and natural systems – has remained elusive. In an attempt to work towards such a model, this paper outlines a generic framework for models of socio-hydrology applicable to agricultural catchments, made up of six key components that combine to form the coupled system dynamics: namely, catchment hydrology, population, economics, environment, socioeconomic sensitivity and collective response. The conceptual framework posits two novel constructs: (i) a composite socioeconomic driving variable, termed the Community Sensitivity state variable, which seeks to capture the perceived level of threat to a community's quality of life, and acts as a key link tying together one of the fundamental feedback loops of the coupled system, and (ii) a Behavioural Response variable as the observable feedback mechanism, which reflects land and water management decisions relevant to the hydrological context. The framework makes a further contribution through the introduction of three macro-scale parameters that enable it to normalise for differences in climate, socioeconomic and political gradients across study sites. In this way, the framework provides for both macro-scale contextual parameters, which allow for comparative studies to be undertaken, and catchment-specific conditions, by way of tailored "closure relationships", in order to ensure that site-specific and application-specific contexts of socio-hydrologic problems can be accommodated. To demonstrate how such a framework would be applied, two socio-hydrological case studies, taken from the Australian experience, are presented and the parameterisation approach that would be taken in each case is discussed. Preliminary findings in the case studies lend support to the conceptual theories outlined in the framework. It is envisioned that the application of this framework across study sites and gradients will aid in developing our understanding of the fundamental interactions and feedbacks in such complex human–hydrology systems, and allow hydrologists to improve social–ecological systems modelling through better representation of human feedbacks on hydrological processes.

Scientific activities take place within the structured sets of ideas and assumptions that define a field and its practices. The conceptual framework of evolutionary biology emerged with the Modern Synthesis in the early twentieth century and has since expanded into a highly successful research program to explore the processes of diversification and adaptation. Nonetheless, the ability of that framework satisfactorily to accommodate the rapid advances in developmental biology, genomics and ecology has been questioned. We review some of these arguments, focusing on literatures (evo-devo, developmental plasticity, inclusive inheritance and niche construction) whose implications for evolution can be interpreted in two ways—one that preserves the internal structure of contemporary evolutionary theory and one that points towards an alternative conceptual framework. The latter, which we label the ‘extended evolutionary synthesis' (EES), retains the fundaments of evolutionary theory, but differs in its emphasis on the role of constructive processes in development and evolution, and reciprocal portrayals of causation. In the EES, developmental processes, operating through developmental bias, inclusive inheritance and niche construction, share responsibility for the direction and rate of evolution, the origin of character variation and organism–environment complementarity. We spell out the structure, core assumptions and novel predictions of the EES, and show how it can be deployed to stimulate and advance research in those fields that study or use evolutionary biology.

This chapter fleshes out an inductive framework for understanding stasis and critical transitions. The framework has been developed with a lens on Brazil, but to illustrate its wider applicability, this chapter applies the framework very generally to understand the critical transitions in Argentina from the early twentieth century to 2014. The key elements in the framework are beliefs and leadership, which interact synergistically and vary across countries. Because beliefs and leadership cannot be measured rigorously and classified, the use of the framework necessarily involves subjectivity and interpretation. With more case studies applying this framework, more general lessons on the dynamics among beliefs, power, leadership, institutions, policies, and outcomes that form stasis or development can be constructed.

On at least four occasions, Edgar Anderson (1897–1969) began revising his book Plants, man and life (1952). Given both its place in Anderson's career and his place in the development of evolutionary theory in the mid-twentieth century, the emendations are noteworthy. Though a popular work, Plants, man and life served as the distillation of Anderson's ideas on hybridization as an evolutionary mechanism, the need for more scientific attention on domesticated and semi-domesticated plants, and the opportunities such plants provided for the study of evolution. Anderson was an active participant in several key events in what historians have come to call the Evolutionary Synthesis. For example, he and Ernst Mayr shared the 1941 Jesup Lectures on “Systematics and the origin of species”. Anderson's proposed revisions to his book reflect both an attempt to soften certain acerbic comments as well as an attempt to recast the book as a whole.

This chapter points to the ‘pluralization of the lifeworld’ involved in globalization as a key context for changing dissenting spiritualities through the twentieth century. These have included a remarkable upsurge in Spirit-movements that fall under categories such as Pentecostal, charismatic, neo-charismatic, ‘renewalist’, and indigenous Churches. Spirit language is not only adaptive to globalized settings, but brings with it eschatological assumptions. New spiritualities emerge to disrupt existing assumptions with prophetic and often critical voices that condemn aspects of the existing culture, state, and church life. This chapter outlines this process of disruption of the mainstream in case studies drawn from the USA, the UK, India, Africa, and Indonesia, where charismaticized Christianity has emerged and grown strongly in often quite resistant broader cultures.

This book examines the ways in which the biblical book of Esther was read, understood, and used in Muslim lands, from ancient to modern times. It zeroes-in on a selection of case studies, covering works from various periods and regions of the Muslim world, including the Qur’an, premodern historical chronicles and literary works, the writings of a nineteenth-century Shia feminist, a twentieth-century Iranian dictionary, and others. These case studies demonstrate that Muslim sources contain valuable materials on Esther, which shed light both on the Esther story itself and on the Muslim peoples and cultures that received it. The book argues that Muslim sources preserve important, pre-Islamic materials on Esther that have not survived elsewhere, some of which offer answers to ancient questions about Esther, such as the meaning of Haman’s epithet in the Greek versions of the story, the reason why Mordecai refused to prostrate himself before Haman, and the literary context of the “plot of the eunuchs” to kill the Persian king. Furthermore, throughout the book we will see how each author’s cultural and religious background influenced his or her understanding and retelling of the Esther story: In particular, it will be shown that Persian Muslims (and Jews) were often forced to reconcile or choose between the conflicting historical narratives provided by their religious and cultural heritages respectively.

Liberal Democratic

Case studies of Indonesia and Japan illustrate that party-system stability in patronage democracies is deeply affected by the relative autonomy of political brokers. Over the course of a decade, a series of decentralizing reforms in Indonesia weakened patronage-based parties hold on power, with the 2014 election ultimately being a contest between two rival populists: Joko Widodo and Subianto Prabowo. Although Japan was a patronage democracy throughout the twentieth century, the ruling Liberal Democratic Party (LDP) remained robust to outsider appeals even in the context of economic and corruption crises. However, reforms in the 1990s weakened the hold of central factional leaders over individual members of the LDP and their patronage machines. This was instrumental to populist Junichiro Koizumi’s winning of the presidency of the LDP and ultimately the prime ministership of Japan. This chapter also reexamines canonical cases of populism in Latin America.

The Relationship

This chapter juxtaposes brief case studies of African American vernacular dancers from the first half of the twentieth century in order to reexamine the relationship between the ideology of intellectual property law and the traditions of jazz and tap dance, which rely heavily on improvisation. The examples of the blackface performer Johnny Hudgins, who claimed a copyright in his pantomime routine in the 1920s, and of Fred and Sledge, the class-act dance duo featured in the hit 1948 musical Kiss Me, Kate, whose choreography was copyrighted by the white modern dancer Hanya Holm, prompt a rethinking of the assumed opposition between the originality and fixity requirements of copyright law and the improvisatory ethos of jazz and tap dance. Ultimately, the chapter argues that whether claiming or disavowing uniqueness, embracing or resisting documentation, African American vernacular dancers were both advantaged and hampered by copyright law.

Neodymium Magnets

AbstractNeodymium magnets have been in use as a mounting technique for works of art on paper for several years; however, the method is still in its infancy. These very strong magnets provide a valuable addition to the traditional methods of mounting artworks on paper and objects made from paper, textile, or other materials for exhibitions. They offer an interesting and elegant alternative to attachment with adhesives, especially when adhesives may not or cannot be applied to the original work. This article addresses the physical properties and manufacture of the magnets, including their coatings and nomenclature. Three successful case studies of mounting artworks on paper with these “super magnets” are presented here. In addition, the limits and possible difficulties of working with neodymium magnets are addressed, as well as precautionary measures to take when handling them.

In 1903, one hundred years after the Prix de Rome had been created in music composition, women were allowed to participate in the competition for the first time. In 1913, Lili Boulanger became the first woman to win the prize, crowning the efforts of three others-Juliette Toutain, Hélène Fleury, and Nadia Boulanger-to achieve this goal. Their stories are fascinating case studies of the strategies women employed to achieve success and public recognition within the complex framework of French cultural politics at the beginning of the twentieth century.
