This work explores the underlying issues and problems surrounding reflection, describing a selection of initiatives and fulfilling a need for novice reflectors to increase their knowledge. The theoretical underpinnings are presented, along with the realities of using reflection in practice.

Numerous scenarios explain the origin of the eukaryote cell by fusion or endosymbiosis between an archaeon and a bacterium (and sometimes a third partner). We evaluate these hypotheses using the following three criteria. Can the data be explained by the null hypothesis that new features arise sequentially along a stem lineage? Second, hypotheses involving an archaeon and a bacterium should undergo standard phylogenetic tests of gene distribution. Third, accounting for past events by processes observed in modern cells is preferable to (...) postulating unknown processes that have never been observed. For example, there are many eukaryote examples of bacteria as endosymbionts or endoparasites, but none known in archaea. Strictly post‐hoc hypotheses that ignore this third criterion should be avoided. Applying these three criteria significantly narrows the number of plausible hypotheses. Given current knowledge, our conclusion is that the eukaryote lineage must have diverged from an ancestor of archaea well prior to the origin of the mitochondrion. Significantly, the absence of ancestrally amitochondriate eukaryotes (archezoa) among extant eukaryotes is neither evidence for an archaeal host for the ancestor of mitochondria, nor evidence against a eukaryotic host.

Age of Anxiety: Meaning, Identity, and Politics in 21st Century Film and Literature applies historical and contemporary political and rhetorical theory to current popular culture to discuss the problem of the displaced autonomous self and the quest for a meaningful life.

The prevailing economic paradigm, in which a closed circular flow of production and consumption can be described in terms of 'natural laws ' of the equilibrium of market forces, is being challenged by our growing knowledge of complex systems, particularly ecosystems. It is increasingly apparent that neo-classical economics does not reflect social, economic and environmental realities in a world of limited resources. The best way to understand the problems implicit in the concept of 'sustainable development ' is provided by Ecological (...) Economics – a new synthesis in which the traditional virtue of thrift is justified using modern ideas from systems theory and thermodynamics. (shrink)

Some forty years on from the great events of the Second Vatican Council, there is still much debate about the interpretation of the Council and its documents. In recent years there has been what might be termed a hermeneutical project: to develop an understanding of the complex processes involved in the genesis of the texts and to explore the interactions of the various individuals and groups that helped to shape the Council. What has emerged is a view of the Council (...) as something organic and dynamic. This article seeks to outline the questions that this hermeneutical project has raised; such as the various sources that can be used to interpret the Council, the impact of various theological strands of tradition present at the Council, the authorship of the texts and the methodologies adopted by the Council. It also provides a review of the work that has taken place with this project, especially in the last ten years or so. (shrink)

It is argued that Athenagoras, Leg. 17, draws on Pausanias 1.26.4, and may join Aelian, Pollux, Philostratus and Longus in the list of possible readers of the periegete.

Restless Ideas is a lively new textbook of contemporary social theory that speaks directly to the anxious age in which we live today. In addition to providing a highly readable guided tour of major social theories from the mid-20th to the early 21st century, this book is full of dynamic examples that show how these theories may be used to deepen our understanding of current events and of our own life experiences. The emergence of demagogic political leaders like Donald Trump (...) in the USA, Rodrigo Duterte in the Philippines, and Recep Tayyip Erdoğan in Turkey; the rise of religious fundamentalism, terrorism, and political populism; the digital echo-chamber of social media; and the underlying causes of Brexit are only some of the many current social issues that can be framed through contemporary social theories. Similarly, the politics of sexual, racial and ethnic minorities can be analyzed through the prism of theoretical perspectives such as queer theory, standpoint and intersectional theory, postcolonial theory and critical race theory, while the ongoing struggles for gender equality and gender justice can usefully be examined through the generational perspectives of feminist theories. This book sets the stage with a critical discussion of the loaded history of the social theory canon and makes the argument that there has never been a better time than the present to broaden our understanding of our shared global heritage of social theory, to include some of the formerly excluded classics of past social thinkers, and to open the doors to current social thinkers theorizing from the margins. The book traces the modern roots of contemporary social theory back to the works of the early structural functionalists, systems theorists, conflict theorists, symbolic interactionists, ethnomethodologists and sociobiologists, building on and at times inverting the canon with the critical advancements to social theory. Later chapters focus on the current influence of structuration theory, third wave critical theory, postmodernism and poststructuralism, critical race theory, postcolonialism, liquid and late modernity theories, and globalization theories. These perspectives include the works of contemporary social theorists such as Anthony Giddens, Pierre Bourdieu, Juliet Mitchell, Dorothy Smith, Judith Butler, Jean-Francois Lyotard, Jacques Derrida, Jean Baudrillard, Gayatri Spivak, Homi K. Bhabha, Zygmunt Bauman, Slavoj Zizek, Alain Badiou, Jürgen Habermas, Axel Honneth, Nancy Fraser, Manuel Castells and Ulrich Beck. The underlying premise - and the promise - of this book is that social theory has the power to provide us with the skills for more informed observation, analysis, and empathic understanding of social behavior and social interaction. In a word: the value of social theory may be seen in how it can enhance social literacy - by deepening our understanding of the world around us, and by empowering us to become practical theorists in our own lives.

Near the beginning of the Nicomachean Ethics, Aristotle claims that “our discussion will be adequate if its degree of clarity reflects the subject matter.” Those who seek to give a proper “theoretical” account of some enterprise, but who neglect this wise Aristotelian counsel, do so at their own peril. Aristotle is urging that sound theory should reflect and elucidate actual practice. When philosophical speculation loses touch with such practice, it tends to caricature what it ought to clarify. For example, Steven (...) Weinberg points out the disparity that often exists between the view of science one finds expounded by some contemporary “philosophers of science” and that presupposed by those really engaged in scientific research: “From time to time I have tried to read current work on the philosophy of science.

"Joseph Marechal, who became one of the most important figures in the twentieth-century revival of the thought of St. Thomas Aquinas, set for himself an ambitious intellectual project. His goal was to demonstrate that the realist theory of knowledge first enunciated by Aristotle in the ancient world and developed by Aquinas in the thirteenth century is the key to a coherent philosophy of man and being. According to Marechal, once late medieval philosophy moved away from Aquinas's epistemological foundations, no longer (...) could it construct a satisfactory unity of knowledge, man, and being. Thus modern Western philosophers, specifically Descartes, began their quest to elaborate an adequate intellectual account of human experience on the basis of a flawed philosophical legacy."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Scholars have long pointed to the power of music as a primary source in instruction for bringing past actors into sharper view and engender deeper connections with the past. By employing Dimitri Shostakovich's 7th Symphony, composed amidst the Nazi siege of Leningrad during the Second World War, we sought to explore, more precisely, the nature of how music, as a primary source, enhances the study of history among students. Through the formulation, execution, and assessment of a two-day lesson with students (...) in five secondary history classes, three of which listened to the symphony and two of which did not, we found that the incorporation of the symphony resulted in students’ enhanced empathetic understanding of the past. Implications include details regarding profound opportunities for, as well as challenges to, cultivating historical empathy through the use of music as a primary source. (shrink)

The study of a middle school social studies and literacy project this paper addresses occurred in the national capital region of the United States, where perceptions of “patriotism” and immigration policies were the subjects of frequent media reports. With this examination the authors considered one overarching research question: how do middle school students describe and illustrate citizenship when given access to multimodal texts and media (e.g., digital photography and slam poetry)? The authors called on young adolescents to create slam poems (...) with incorporated images to address the question “What does it mean to be a ‘citizen’?”. The authors examined products of this project, which included surveys and slam poems, to address this research question, identifying findings that might inform social studies educators’ practices and curricula. Employing alternative and multimodal texts motivated students to engage with this project and to more candidly share expansive perspectives about what they believe makes a “citizen”. (shrink)

In these days of inflation, perhaps we should not be surprised that the fourteenth and latest addition to the Library of Living Philosophers, should require two volumes. Previous subjects, including Bertrand Russell, Albert Einstein and G.E. Moore, were adequately accomodated within the covers of one volume. This expansion is hardly justified by the contents of the volumes. The most interesting and useful material is to be found in Popper's opening autobiographical section, but the other contributors and critics for the most (...) part are disappointing in their lack of critical bite.For this reason perhaps Popper's reply to his critics adds little to our understanding of his philosophical positions, although even when his critic is as acute as A.J. Ayer, Popper's reply has an air of defensive obfuscation.Another recent book giving a brief but clear exposition of Popper's philosophy by a former student, Bryan Magee also fails to give his views the critical examination they deserve.

Classic studies in human sensorimotor control use simplified tasks to uncover fundamental control strategies employed by the nervous system. Such simple tasks are critical for isolating specific features of motor, sensory, or cognitive processes, and for inferring causality between these features and observed behavioral changes. However, it remains unclear how these theories translate to complex sensorimotor tasks or to natural behaviors. Part of the difficulty in performing such experiments has been the lack of appropriate tools for measuring complex motor skills (...) in real-world contexts. Robot-assisted surgery (RAS) provides an opportunity to overcome these challenges by enabling unobtrusive measurements of user behavior. In addition, a continuum of tasks with varying complexity – from simple tasks such as those in classic studies to highly complex tasks such as a surgical procedure – can be studied using RAS platforms. Finally, RAS includes a diverse participant population of inexperienced users all the way to expert surgeons. In this perspective, we illustrate how the characteristics of RAS systems make them compelling platforms to extend many theories in human neuroscience, as well as, to develop new theories altogether.
