During late embryonic and early postnatal development, synaptic connections are extensively modified so that some functional connections are weakened and eliminated from a neural circuit while others are strengthened and maintained. The mechanisms that underlie synapse elimination are beginning to be understood from studies of the neuromuscular junction. A recent paper(1) provides some intriguing insights into the role proteases may play in the developmental disassembly of neuromuscular synapses.

This article focuses on mirror self-recognition, the ability to recognize one's own image in a mirror. It presents the result of the first experiment on mirror self-recognition which showed that chimpanzees are able to learn that the chimps they see in the mirror are not other chimps, but themselves, as evidenced by self-directed behaviour. It reviews evidence for neural network for self-recognition and self-other differentiation and cites evidence that frontal cortex and cortical midline structures are implicated in self-recognition tasks. It (...) also suggests that the mirror self-recognition ability correlates to large brain size relative to the animal's body size. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.1 (2003) 1-21 [Access article in PDF] Did Habermas Cede Nature to the Positivists? Gordon R. Mitchell Jürgen Habermas's "colonization of the lifeworld" thesis (1987, 332-73) posits that many of society's pathologies are due to the tendency of institutions to convert social issues that ought to be sorted out by a debating citizenry into technical problems ripe for resolution by expert bureaucracies, thus pre-empting important (...) public discussion. Habermas has attempted to lay bare the pernicious effects of this colonization process in his analysis of public opinion polling, welfare policy, education, German reunification, immigration, and other social issues (see Habermas 1997, 1994, and 1970; Holub 1992). In each of these contexts, Habermas has publicly challenged the encroachment of scientistic modes of decision-making into spheres where joint communicative action by deliberating citizens would yield more appropriate and legitimate judgments. This critical impulse is also evident in Habermas's methodological reflections on the proper role of academic scholarship, where he has argued vigorously against attempts to graft "objectivating" methods of natural scientific inquiry onto research projects in the social sciences (1971, 304-17).From all of this, one might gather that Habermas's commitment to rolling back the influence of technical forms of reasoning is connected to some intrinsic quarrel he has with the natural sciences. Yet such a sweeping generalization is hard to sustain in light of the fact that Habermas does not oppose technical reasoning per se; he recognizes that the daunting complexity of social life in late capitalism requiresthat certain "steering" tasks be delegated to systems that utilize largely instrumental logics to co-ordinate action. Likewise, he acknowledges that the disciplines of the natural sciences necessarily play important supporting roles in such steering projects.One normative presupposition of Habermas's colonization thesis is that there exists some proper boundary demarcating where the sphere of technical reasoning ends and the realm of communicative rationality begins. [End Page 1] On one side of this boundary, Habermas has provided many details on what he sees as the essential qualities of a properly functioning "public sphere," where "new social movements" continuously reweave the threads of communicative fabric holding society together (1996, 359-87), and where "historico-hermeneutic" academic study reflects on public life, sluicing insight back into the capillaries of democratic deliberations (1987, 374-403).What lies on the other side of the boundary is murkier. The proper role of natural scientific investigation has received relatively scant attention in Habermas's critical theory of society, and this has led to some confusion regarding his account of the natural sciences, as well as debate over whether this account has political purchase. One would think that sympathetic commentators, such as Helen Longino (who bases much of her own coherence theory of scientific truth on Habermas), would have reassuring things to say on this point. Yet her lukewarm assessment that, "in trying to clear a space for an autonomous social and critical theory, [Habermas] has ceded nature to the positivists" (1990, 202), raises questions about the flexibility and scope of Habermas's theory of communicative action as a basis for critique of scientific practice.One way to test Habermas's account of the natural sciences on this count is to put his views in conversation with science studies commentators who share a similar commitment to the idea that dialogue and argumentation are constitutive elements of scientific practice. Such an approach recasts the "ceding to positivism" question into a moment of controversy over the role of dialogue, not only as an essential motor driving the scientific enterprise, but also as a vehicle for democratic decision-making on issues related to the purpose and direction of scientific inquiry in society.Part one of this essay locates discursive norms embedded pragmatically in the notion of scientific objectivity. By bringing a modified version of Habermas's theory of communicative action into conversation with other approaches to science studies that foreground intersubjective dialogue as the key motor driving the scientific enterprise, I develop a foundation for robust criticism of systematically distorted scientific communication. Specific strategies of... (shrink)

In a critical discussion, interlocutors can strategically maneuver by shading their expressed degree of standpoint commitment for rhetorical effect. When is such strategic shading reasonable, and when does it cross the line and risk fallacious derailment of the discussion? Analysis of President George W. Bush’s 2002–2003 prewar commentary on Iraq provides an occasion to explore this question and revisit Douglas Ehninger’s distinction between argumentation as coercive correction and argumentation as a person-risking enterprise. Points of overlap between Ehninger’s account and pragma-dialectical (...) argumentation theory suggest avenues for harmonization of rhetorical and dialectical perspectives on argumentation. Out of this conceptual convergence comes theoretical resources for understanding strategic maneuvering, by accounting for ways that discussants exploit gaps between their externalized and actual discussion attitude. As such higher-order strategic maneuvering played a major role in the 2003 Iraq prewar discourse failure, perspicacious understanding of this particular argumentative maneuver carries practical, as well as theoretical import.

While many "benchtop-to-bedside" research pathways have been developed in "Type I" translational medicine, vehicles to facilitate "Type II" and "Type III" translation that convert scientific data into clinical and community interventions designed to improve the health of human populations remain elusive. Further, while a high percentage of physicians endorse the principle of citizen leadership, many have difficulty practicing it. This discrepancy has been attributed, in part, to lack of training and preparation for public advocacy, time limitation, and institutional resistance. As (...) translational medicine and physician-citizenship implicate social, political, economic and cultural factors, both enterprises require "integrative" research strategies that blend insights from multiple fields of study, as well as rhetorical acumen in adapting messages to reach multiple audiences. This article considers how argumentation theory's epistemological flexibility, audience attentiveness, and heuristic qualities, combined with concepts from classical rhetoric, such as rhetorical invention, the synecdoche, and ethos, yield tools to facilitate translational medicine and enable physician-citizenship.

This book engages in critical discussion of the role of reason and rationality in philosophy, the human mind, ethics, science, and the social sciences. Philosophers from Poland, Germany, and the United States examine reason in the light of emotion, doubt, absolutes, implementation, and interpretation. They throw new light on old values.

_Philosophy and Vision_ argues that clear thinking and imaginative understanding are necessary qualities as we try to deal with the problems that confront us in our daily life. The book discusses history, the environment, religion, personal and corporate morality, freedom, the concept of person, poetry, and post-modernism attempts to show that as a philosophic vision is brought to bear on all of these, we will grasp them more completely and more constructively. The issues which challenge most of us seldom have (...) straightforward answers, but they require some answers, some response other than failing out of our emotions. Attempting to see these philosophically, to adopt a philosophic vision, is no panacea, but it may make the difference between being overwhelmed and being able to cope. The book has a crisp enjoyable style, and while it is a philosophical work it draws upon movies, fiction, poetry, and life's experiences in developing its arguments. (shrink)

The contention that cognitive psychology and radical behaviorism yield equivalent accounts of decision making and problem solving is examined by contrasting a framework of cognitive interpretation, Dennett's intentional stance, with a corresponding interpretive stance derived from contextualism. The insistence of radical behaviorists that private events such as thoughts and feelings belong in a science of human behavior is indicted in view of their failure to provide a credible interpretation of complex human behavior. Dennett's interpretation of intentional systems is an exemplar (...) of the interpretive stance radical behaviorism requires; a corresponding interpretive position can be based initially on a radical behaviorist view of human behavior and its determinants. This "contextual stance" is ontologically and methodologically distinct from the intentional stance over the range of explanations for which scientific psychology, cognitive or behaviorist, is responsible.

In 2000, US Secretary of Health and Human Services Secretary Tommy Thompson mobilized the US public health infrastructure to deal with escalating trends of excess body weight. A cornerstone of this effort was a report entitled The Surgeon General's Call to Action to Prevent and Decrease Overweight and Obesity. The report stimulated a great deal of public discussion by utilizing the distinctive public health terminology of an epidemic to describe the growing prevalence of obesity in the US population. We suggest (...) that the ensuing controversy was fueled in part by the report's ambiguous usage of the evocative term “epidemic.” In some passages, the report seems to use “epidemic” in a literal sense, suggesting that rising prevalence of excess body weight should be defined technically as a disease outbreak. Other passages of the report present the same key term metaphorically, leaving readers with the impression that the epidemic language is invoked primarily for rhetorical effect. Here, we explore dynamics and implications of both interpretations. This analysis sheds light on the ongoing public argument about the appropriate societal response to steadily increasing body sizes in the US population; likewise, it capitalizes on the accumulated knowledge that the field of public health has garnered from combating diverse historic epidemics. Our interdisciplinary approach deploys critical tools from the fields of rhetoric, sociology and epidemiology. In particular, we draw from metaphor theory and public address scholarship to elucidate how the Call to Action frames public deliberation on obesity. We turn to the applied public health literature to develop a reading of the report that suggests a novel approach to the problem—application of the Epidemic Investigation protocol to streamline the public health response and reframe the public argument about obesity.

Apparent design breakthroughs in short-range missile defense systems such as Theater High-Altitude Air Defense have prompted questions about the legality of such systems under the 1972 Antiballistic Missile Treaty. Prominent physicists have used computer “footprint” methodology to prove that if engineered to specifications, THAAD might exceed ABM Treaty performance limits banning highly effective missile defense systems. In response, missile defense officials commissioned Sparta, Inc. to conduct secret research casting doubt on the validity of such findings. The substantial diplomatic issues at (...) stake and the interesting rhetorical dynamics involved in this dispute warrant close scholarly analysis. Attention to the iterative relationship between the interpenetrating spheres of public argument and scientific practice in this case yields novel insight about the processes in which technical knowledge of defense systems is forged and raises fresh issues for the “closure project” in science and technology controversy studies.

This paper’s purpose is to provide a foundation for viewing critical thinking as both a maximal and typical performance construct. While maximal performance measures the best a person can do, typical performance measures what the person is most likely to do. An overview of maximal performance, including its history and limitations, will be given. The role of maximal and typical performance in cognitive development will be demonstrated through an exploration of the relationships between behavior, the environment, personality, crystallized intelligence, and (...) fluid intelligence. Furthermore, these topics will be related to the development and use of critical thinking skills. Discussion will conclude with directions for future research. (shrink)

Epictetus was born a slave. His master, Epaphroditus, allowed him to attend the lectures of the Stoic philosopher Musonius Rufus and later gave him his freedom. From numerous references in his Discourses it is clear that Epictetus valued freedom as a precious possession. He would have been on the side of the many people living now who, while not actually enslaved, are denied true freedom by the harsh circumstances of their lives. Epictetus's teachings about freedom and human dignity have echoed (...) through the millennia-in the writings of Spinoza, Thomas Paine and Martin Luther King, Jr., to name a few. He was much concerned with human behavior. His advice to not worry about what is not in our control is pointedly relevant to our busy modern society-which is often fraught with anxiety. Some people might argue that what Epictetus taught is not serious philosophy, more like self-help. But the range of topics addressed by the essays in this book clearly indicates that the teachings of Epictetus provide strong incentive to present day philosophical thinking. "Epictetus: His Continuing Influence and Contemporary Relevance" is the title of a conference on Epictetus held at Rochester Institute of Technology in April 2012, when many of the ideas in these essays were first presented.

The intentional stance1 and the contextual stance2 are inextricably interdependent in the production of a comprehensive explanation and means of predicting complex human behaviour. This is illustrated in the context of the expectation of attitudinal-behavioural consistency which has long lain at the heart of both marketing science and social psychology. In practice, cognitively-inclined attitude theory and research leans on the contextual stance in order to formulate the heuristic overlay of mental interpretation in which it primarily presents its predictive and explicative (...) accounts of behaviour. Behaviour analysis has traditionally eschewed this approach, maintaining that it can generate an exclusively extensional account of complex behaviour. It is argued that while the cognitive and behaviour analytic approaches produce equally effective predictions of behaviour, an adequate explanation of human activity requires the addition of the kind of interpretive overlay advocated by Dennett3 in which the relationship between extensional science and intensionalistic interpretation is clarified. The resulting framework of analysis, intentional behaviorism4 provides an inclusive paradigm. (shrink)
