Making recognition decisions often requires us to reference the contents of working memory, the information available for ongoing cognitive processing. As such, understanding how recognition decisions are made when based on the contents of working memory is of critical importance. In this work we examine whether recognition decisions based on the contents of visual working memory follow a continuous decision process of graded information about the correct choice or a discrete decision process reflecting only knowing and guessing. We find a (...) clear pattern in favor of a continuous latent strength model of visual working memory–based decision making, supporting the notion that visual recognition decision processes are impacted by the degree of matching between the contents of working memory and the choices given. Relation to relevant findings and the implications for human information processing more generally are discussed. (shrink)

Multiple -conclusion logic extends formal logic by allowing arguments to have a set of conclusions instead of a single one, the truth lying somewhere among the conclusions if all the premises are true. The extension opens up interesting possibilities based on the symmetry between premises and conclusions, and can also be used to throw fresh light on the conventional logic and its limitations. This is a sustained study of the subject and is certain to stimulate further research. Part I reworks (...) the fundamental ideas of logic to take account of multiple conclusions, and investigates the connections between multiple - and single - conclusion calculi. Part II draws on graph theory to discuss the form and validity of arguments independently of particular logical systems. Part III contrasts the multiple - and the single - conclusion treatment of one and the same subject, using many-valued logic as the example; and Part IV shows how the methods of 'natural deduction' can be matched by direct proofs using multiple conclusions.

The most complete and detailed book devoted to middle range theories, this text examines theories and their applications in clinical nursing research and practice. The authors provide expert advice on selecting an appropriate theory for a nursing research project and on critiquing theories. The most frequently cited middle range nursing theories are explored in individual chapters. Each theory chapter includes examples of the theory's use in research, sample application of the theory, analysis exercises, and critical thinking exercises. The Third Edition (...) includes new chapters on Attachment theory and the Shuler Nurse Practitioner Practice Model. (shrink)

High school students are at risk for increased sedentary behavior due in part to a decrease in physical activity throughout adolescence and to required sedentary behavior during much of the school day. The purpose of the current study is to examine the impact of using activity workstations in a high school English class for struggling readers. Twenty high school students participated in the study. The participants completed a 16-week study where each participant used an activity workstation for 8 weeks and (...) a traditional desk for 8 weeks in a crossover design for a 40-min period during normal class. They responded to a series of subjective questions about reading and schoolwork at the beginning and end of each 8-week session and followed the READ 180 program designed to help struggling readers during the study. The results indicated that academic performance increased in both desk conditions during the study and from the beginning to the end of the study. In addition, there was a significant improvement in items in the subjective survey related to reading, motivation, and schoolwork in both desk conditions across the study. The current results suggest that using an activity workstation in the classroom did not negatively affect academic performance or students’ perceptions of working on academic assignments compared to the traditional desk condition. These results indicate that activity workstations could be implemented in classrooms to provide students with a non-sedentary option during the school day thus increasing physical activity in students.

Some skeptical theists use Wykstra’s CORNEA constraint to undercut Rowe-style inductive arguments from evil. Many critics of skeptical theism accept CORNEA, but argue that Rowe-style arguments meet its constraint. But Justin McBrayer argues that CORNEA is itself mistaken. It is, he claims, akin to “sensitivity” or “truth-tracking” constraints like those of Robert Nozick; but counterexamples show that inductive evidence is often insensitive. We here defend CORNEA against McBrayer’s chief counterexample. We first clarify CORNEA, distinguishing it from a deeper underlying principle (...) that we dub “CORE.” We then give both principles a probabilistic construal, and show how, on this construal, the counterexample fails.

We will study patterns which occur when considering how Σ 1 -elementary substructures arise within hierarchies of structures. The order in which such patterns evolve will be seen to be independent of the hierarchy of structures provided the hierarchy satisfies some mild conditions. These patterns form the lowest level of what we call patterns of resemblance . They were originally used by the author to verify a conjecture of W. Reinhardt concerning epistemic theories 449–460; Ann. Pure Appl. Logic, to appear), (...) but their relationship to axioms of infinity and usefulness for ordinal analysis were manifest from the beginning. This paper is the first part of a series which provides an introduction to an extensive program including the ordinal analysis of set theories. Future papers will conclude the introduction and establish, among other things, that notations we will derive from the patterns considered here represent the proof-theoretic ordinal of the theory KPℓ 0 or, equivalently, Π 1 1 −CA 0.

Fallacies are things people commit, and when they commit them they do something wrong. What kind of activities are people engaged in when they commit fallacies, and in what way are they doing something wrong? Many different things are called fallacies. The diversity of the use of the concept of a fallacy suggests that we are dealing with a family of cases not related by a common essence. However, we suggest a simple account of the nature of fallacies which encompasses (...) them all, viz., the term “fallacy” is our most general term for criticizing any general procedure used for the fixation of beliefs that has an unacceptably high tendency to generate false or unfounded beliefs, relative to that method of fixing beliefs. Very different sorts of things called fallacies are examined in the light of this account, e.g., denying the antecedent, circular arguments, so-called informal fallacies, and propositions said to be fallacies. We do not provide a theory of fallacies. Still, on our account pretty much all of those things that have been called fallacies are fallacies, and they have been called fallacies for pretty much the same reasons. (shrink)

Karl Barth was the most prolific theologian of the twentieth century. Avoiding simple paraphrasing, Dr Gorringe places the theology in its social and political context, from the First World War through to the Cold War by following Barth's intellectual development through the years that saw the rise of national socialism and the development of communism. Barth initiated a theological revolution in his two Commentaries on Romans, begun during the First World War. His attempt to deepen this during the turbulent years (...) of the Weimar Republic made him a focus of theological resistance to Hitler after the rise to power of the Nazi party. Expelled from Germany, he continued to defy fashionable opinion by refusing to condemn communism after the Second World War. Drawing on a German debate largely ignored by Anglo-Saxon theology Dr Gorringe shows that Barth responds to the events of his time not just in his occasional writings, but in his magnum opus, the Church Dogmatics. In conclusion Dr Gorringe asks what this admittedly patriarchal author still has to contribute to contemporary theology, and in particular human liberation. (shrink)

One of the fundamental components of the concept of economic rationality is that preference orderings are “complete,” i.e., that all alternative actions an economic agent can take are comparable. The idea that all actions can be ranked may be called the single utility assumption. The attractiveness of this assumption is considerable. It would be hard to fathom what choice among alternatives means if the available alternatives cannot be ranked by the chooser in some way. In addition, the efficiency criterion makes (...) sense only if one can infer that an individual's choice reflects the best, in expected welfare terms, among all choices that individual could have made. The possibility that a rearrangement of resources could make someone “better off” without making others “worse off” can be understood only if the post-rearrangement world is comparable with the pre-rearrange-ment world.

In the January 6, 1991, issue of the Washington Post Magazine, reporter Walt Harrington wrote a profile of Bryan Stevenson. Mr. Stevenson is a 31-year-old working-class African-American from Delaware who graduated from Harvard Law School and the Kennedy School of Government. Like the typical graduate of Harvard Law School, Mr. Stevenson had the opportunity to join the worlds of six-figure corporate law or high-visibility politics. Rather than follow his colleagues, however, Mr. Stevenson works seven-day, eighty-hour weeks as director of the (...) Alabama Capital Representation Center. He appeals death sentences, handling twenty-four death-row cases himself, supervises five other lawyers who cover about thirty cases, and raises federal government and foundation funding. He does this living a Spartan existence on a salary of $24,000, refusing even the $50,000 directorship salary offered to him. (shrink)

A number of recent scholarly works in Chinese philosophy approach Chinese texts and thinkers by incorporating them into longstanding issues and debates in the Western philosophical tradition. While the merits of this approach have received much discussion among those working in Chinese philosophy, it also has the potential to reach those outside the field whose research or teaching focuses on the debates and issues. In this article we look at the issue of using Chinese philosophy in courses on contemporary philosophical (...) topics for non-specialists. We give the justification for this pedagogical approach, put forth a “syllabus” of preparatory readings, and finally, discuss its limitations and possibilities. (shrink)

Most people dread being the subject of interest for doctors, scientists, regulators, and lawyers. While we may joke about the arrogance of the medical profession and the aggressiveness of the legal field, both lie at the core of environmental public health. They are inseparable, sometimes complementary and other times in tension. The role of medicine and science in EPH is clear, but their relationship with law is often opaque. Yet in no other area of public health, from infectious and chronic (...) disease prevention to providing health care in underserved communities, is law so central as an instrument and partner. In this article we explore the relationship of law and science in the broader context of EPH, beginning with an overview of potential goals and challenges. We then offer three organizing principles that inform and guide the integration of law, science and policy in EPH. (shrink)

Regardless of how health reform proceeds, we will continue to need public insurance programs to care for the poor, cover health problems not addressed by private insurance, and support the nation's health care infrastructure. This article examines that continuing role.

Belief in evolved belief systems stems from using a population-genetic model of evolution that misconstrues the developmental relationship between genes and behaviour, confuses notions of and and ignores the fundamental role of language in the development of human beliefs. We suggest that theories about the evolution of belief would be better grounded in a developmental model of evolution.

As we write this paper in spring 2008, many are hopeful that November’s election will open the door to some form of comprehensive health care reform. In all likelihood, we will elect a president who has campaigned to a greater or lesser extent on promises of improving access to health care, improving quality, and reducing costs. Equally important, it seems likely that the 111th Congress is preparing to undertake meaningful health care reform. And perhaps most important, despite recent attention to (...) energy issues and the economy, opinion polls consistently show that the American public continues to rank health care as one of the two or three most important domestic issues in the fall elections and supports comprehensive health care reform.

Explaining the causal origins of what are taken to be uniquely human capacities for understanding the mind in the first years of life is a primary goal of social cognitive development research, which concerns so called “theory of mind” or “mindreading” skills. We review and discuss particular examples of this research in the context of its underlying evolutionary conceptual framework known as the neo-Darwinian modern synthesis. It is increasingly recognized that the modern synthesis is limited in its neglect of developmental (...) issues. A recent convergence of work from diverse sources, including but not limited to evolutionary developmental biology (evo-devo) and developmental systems approaches, demonstrate the need for a developmental expansion of modern evolutionary theory. We attempt to show that not only are nativist explanations of early human social cognition vulnerable to the criticisms of this developmental shift in thinking, but that these criticisms also problematize the dominant and more mainstream theories in early social cognitive development research. We conclude by discussing the importance of developmental analysis in understanding the ontogeny of cognitive capacities in individuals as well as species. (shrink)

Applying a non-developmental evolutionary metatheory to understanding the evolution of psychological capacities leads to the creation of models that mischaracterize developmental processes, misattribute genes as the source of developmental information, and ignore the myriad developmental and contextual factors involved in human decision-making. Using an evolutionary systems perspective, we argue that revenge and forgiveness cannot be understood apart from the development of foundational human psychological capacities and the contexts under which they develop.

At any given time, a subject has a multiplicity of conscious experiences. A subject might simultaneously have visual experiences of a red book and a green tree, auditory experiences of birds singing, bodily sensations of a faint hunger and a sharp pain in the shoulder, the emotional experience of a certain melancholy, while having a stream of conscious thoughts about the nature of reality. These experiences are distinct from each other: a subject could experience the red book without the singing (...) birds, and could experience the singing birds without the red book. But at the same time, the experiences seem to be tied together in a deep way. They seem to be unified, by being aspects of a single encompassing state of consciousness. (shrink)

In this paper we defend the doxastic conception of delusions against the metacognitive account developed by Greg Currie and collaborators. According to the metacognitive model, delusions are imaginings that are misidentified by their subjects as beliefs: the Capgras patient, for instance, does not believe that his wife has been replaced by a robot, instead, he merely imagines that she has, and mistakes this imagining for a belief. We argue that the metacognitive account is untenable, and that the traditional conception of (...) delusions as beliefs should be retained. (shrink)

Introduction of O2 to Earth's early biosphere stimulated remarkable evolutionary adaptations, and a wide range of electron acceptors allowed diverse, energy-yielding metabolic pathways. Enzymatic reduction of O2 yielded a several-fold increase in energy production, enabling evolution of multi-cellular animal life. However, utilization of O2 also presented major challenges as O2 and many of its derived reactive oxygen species are highly toxic, possibly impeding multicellular evolution after the Great Oxidation Event. Remarkably, ROS, and especially hydrogen peroxide, seem to play a major (...) part in early diversification and further development of cellular respiration and other oxygenic pathways, thus becoming an intricate part of evolution of complex life. Hence, although harnessing of chemical and thermo-dynamic properties of O2 for aerobic metabolism is generally considered to be an evolutionary milestone, the ability to use ROS for cell signaling and regulation may have been the first true breakthrough in development of complex life. The importance of Earth's oxygen cycle and reactive oxygen species produced on the evolution of complex life. The ability to detoxify oxygen species is not a trait that emerged as a response to increased O2 levels but rather crucial adaptation to the early Earth's weakly oxic microenvironments. (shrink)

What we call “the evidential argument from evil” is not one argument but a family of them, originating (perhaps) in the 1979 formulation of William Rowe. Wykstra’s early versions of skeptical theism emerged in response to Rowe’s evidential arguments. But what sufficed as a response to Rowe may not suffice against later more sophisticated versions of the problem of evil—in particular, those along the lines pioneered by Paul Draper. Our chief aim here is to make an earlier version of skeptical (...) theism more responsive to the type abductive atheology pioneered by Draper. In particular, we suggest a moderate form of skeptical theism may be able to resist Draper’s abductive atheology. (shrink)

The good in nature and humanity brings together 20 leading thinkers and writers - including Ursula Goodenough, Lynn Margulis, Dorion Sagan, Carl Safina, David Petersen, Wendell Berry, Terry Tempest Williams, and Barry Lopez - to examine the divide between faith and reason, and to seek a means for developing an environmental ethic that will help us confront two of our most imperiling crises: global environmental destruction and an impoverished spirituality. The book explores the ways in which science, spirit, and religion (...) can guide the experience and understanding of our ongoing relationship with the natural world and examines how the integration of science and spirituality can equip us to make wiser choices in using and managing the natural environment. The book also provides compelling stories that offer a narrative understanding of the relations among science, spirit, and nature. Grounded in the premise that neither science nor religion can by itself resolve the prevailing malaise of environmental and moral decline, contributors seek viable approaches to averting environmental catastrophe and, to achieving a more harmonious relationship with the natural world.

Disorders of volition are often accompanied by, and may even be caused by, disruptions in the phenomenology of agency. Yet the phenomenology of agency is at present little explored. In this paper we attempt to describe the experience of normal agency, in order to uncover its representational content.
