The current study examined the effects of cardiorespiratory fitness, identified with a continuous graded cycle ergometry, and aerobic exercise on cognitive functioning and entropy of the electroencephalogram (EEG) in 30 adolescents between the ages of 13 and 14 years. Higher and lower fit participants performed an executive function task after a bout of acute exercise and after rest while watching a film. EEG entropy, using the sample entropy measure, was repeatedly measured during the 1500ms post-stimulus interval to evaluate changes in (...) entropy over time. Analysis of the behavioural data for lower and higher fit groups revealed an interaction between fitness levels and acute physical exercise. Notably, lower fit, but not higher fit, participants had higher error rates for NoGo relative to Go trials in the rest condition, whereas in the acute exercise condition there were no differences in error rates between groups; higher fit participants also had significantly faster reaction times in the exercise condition in comparison with the rest condition. Analysis of EEG data revealed that higher fit participants demonstrated lower entropy post-stimulus than lower fit participants in the left frontal hemisphere, possibly indicating increased efficiency of early stage stimulus processing and more efficient allocation of cognitive resources to the task demands. The results suggest that EEG entropy is sensitive to stimulus processing demands and varies as a function of physical fitness levels, but not acute exercise. Physical fitness, in turn, may enhance cognition in adolescence by facilitating higher functionality of the attentional system in the context of lower levels of frontal EEG entropy. (shrink)

Forensic evaluations of insanity have recently borne witness to an influx of neuroimaging methods, especially structural and functional magnetic resonance imaging and positron emission tomography, to assist in the development of explanations that help to excuse legal responsibility for criminal behavior. The results of these scanning methods have been increasingly introduced in legal settings to offer or support a clinical diagnosis that in turn suggests that an individual was incapable of knowing right from wrong, or to pinpoint brain dysfunction suggestive (...) of an inability to control behavior. This paper examines how neuroimaging has been employed in insanity evaluations. After addressing the contentious use of neuroimaging scans in insanity evaluations and synthesizing relevant research, we conclude that such scans presently hold limited applicability for forensic determinations of insanity. Furthermore, they can in some cases distract the trier of fact, potentially leading to erroneous conclusions. (shrink)

We propose a notion of a sub-model for each agent at each state in the Heifetz et al. model of interactive unawareness. Presuming that each agent is fully cognizant of his sub-model causes no difficulty and fully describes his knowledge and his beliefs about the knowledge and awareness of others. We use sub-models to motivate the HMS conditions on possibility correspondences.

We use formal semantic analysis based on new constructions to study abstract realizability, introduced by Läuchli in 1970, and expose its algebraic content. We claim realizability so conceived generates semantics-based intuitive confidence that the Heyting Calculus is an appropriate system of deduction for constructive reasoning.Well-known semantic formalisms have been defined by Kripke and Beth, but these have no formal concepts corresponding to constructions, and shed little intuitive light on the meanings of formulae. In particular, the completeness proofs for these semantics (...) do not generate confidence in the sufficiency of the Heyting Calculus, since we have no reason to believe that every intuitively constructive truth is valid in the formal semantics.Läuchli has proved completeness for a realizability semantics with formal concepts analogous to constructions. We argue in some detail that, in spite of a certain inherent inexactness of the analogy, every intuitively constructive truth is valid in Läuchli semantics, and therefore the Heyting Calculus is powerful enough to prove all constructive truths. Our argument is based on the postulate that a uniformly constructible object must be communicable in spite of imprecision in our language, and that the permutations in Läuchli's semantics represent conceivable imprecision in a language, while allowing a certain amount of freedom in choosing the particular structure of the language.We give a detailed generalization of Läuchli's proof of completeness for the propositional part of the Heyting Calculus, in order to make explicit constructive and algebraic content.In our treatment, we establish several new results about Läuchli models. We show how to extend the sconing and gluing constructions familiar from Kripke and Frame semantics and Topos theory, to Läuchli models, and use them to give an algebraic approach to countermodel construction. In particular, the Läuchli arguments are given without the restriction to the integers, Z, as a group of permutations, which makes much of the coding scheme used in Läuchli's original paper transparent.We also make use of a new propositions-as-types syntax for the Heyting calculus, with limited nondeterminism, in which validity of formulae can be decided without loop-detection.

Archaeologists have proposed that behavioral knowledge of a tool can be conceptualized as a “recipe”—a unit of cultural transmission that combines the preparation of raw materials, construction, and use of the tool, and contingency plans for repair and maintenance. This parallels theories in cognitive psychology that behavioral knowledge is hierarchically structured—sequences of actions are divided into higher level, partially independent subunits. Here we use an agent-based simulation model to explore the costs and benefits of hierarchical learning relative to holistic learning, (...) where entire behavioral sequences are learned in an all-or-nothing fashion, and diffusionist learning, where actions are completely independent. Hierarchical learning is favored under the reasonable assumptions that learning is associated with some degree of both error and cost, and that behavior can be grouped into subunits that repeat in one or more tool recipes. These general predictions can be tested in the archaeological and ethnographic record. Recent advances in evolutionary developmental biology have revealed a number of parallels between the hierarchically structured, recipe-like organization of behavioral knowledge that we examine here and the manner in which biological organisms develop.

This book is an in-depth treatment of Darwinian evolutionism and its applicability to the investigation of the archaeological record. The authors explain the unique position that this kind of evolutionism holds in science and how it bears on any attempt to explain change over time in the organic world, demonstrate commonalities between archaeology and paleobiology, and explain the principles, methods, and techniques - the systematics - inherent in the approach.

This review summarizes and critiques the empirical ethical decision-making literature from 1996-2003. One hundred and seventy-four articles were published in top business journals during this period. Tables are included that summarize the findings by dependent variable - awareness, judgment, intent, and behavior. We compare this review with past reviews in order to draw conclusions regarding trends in the ethical decision-making literature and to surface directions for future research.

This paper reports an experiment designed to investigate the potential influence of prior acts of self-control on subsequent prospective memory performance. College undergraduates performed either a cognitively depleting initial task or a less resource-consuming version of that task . Subsequently, participants completed a prospective memory task that required attentionally demanding monitoring processes. The results demonstrated that prior acts of self-control do not impair the ability to execute a future intention in college-aged adults. We conceptually replicated these results in three additional (...) depletion and prospective memory experiments. This research extends a growing number of studies demonstrating the boundary conditions of the resource depletion effect in cognitive tasks. (shrink)

ABSTRACT There is limited guidance about whether and how to provide psychological assessment results to research participants. This paper considers several ethical challenges associated with offering individual research results in psychological assessment research. Additionally, the process used to return individual results within a study examining neurodevelopmental effects of anesthesia exposure in children and adolescents is described. Almost all participants requested to know if results were concerning; however, only around a third of those with concerning findings sought additional feedback. Ongoing research (...) and guidance are necessary to establish evidence-based practices and manage challenges that may emerge when disclosing such results. (shrink)

Given the importance of cross-disciplinary research, facilitating CDR effectiveness is a priority for many institutions and funding agencies. There are a number of CDR types, however, and the effectiveness of facilitation efforts will require sensitivity to that diversity. This article presents a method characterizing a spectrum of CDR designed to inform facilitation efforts that relies on bibliometric techniques and citation data. We illustrate its use by the Toolbox Project, an ongoing effort to enhance cross-disciplinary communication in CDR teams through structured, (...) philosophical dialogue about research assumptions in a workshop setting. Toolbox Project workshops have been conducted with more than 85 research teams, but the project's extensibility to an objectively characterized range of CDR collaborations has not been examined. To guide wider application of the Toolbox Project, we have developed a method that uses multivariate statistical analyses of transformed citation proportions from published manuscripts to identify candidate areas of CDR, and then overlays information from previous Toolbox participant groups on these areas to determine candidate areas for future application. The approach supplies 3 results of general interest: A way to employ small data sets and familiar statistical techniques to characterize CDR spectra as a guide to scholarship on CDR patterns and trends. A model for using bibliometric techniques to guide broadly applicable interventions similar to the Toolbox. A method for identifying the location of collaborative CDR teams on a map of scientific activity, of use to research administrators, research teams, and other efforts to enhance CDR projects.

Given the numerous parallels between the archaeological and paleontological records, it is not surprising to find a considerable fit between macroevolutionary approaches and methods used in biology – for example, cladistics and clade-diversity measures – and some of those that have long been used in archaeology – for example, seriation. Key, however, is recognizing that this methodological congruence is illusory in terms of how evolution has traditionally been viewed in biology and archaeology. (Published Online November 9 2006).

We agree that the emergence of cumulative technological culture was tied to nonsocial cognitive skills, namely, technical-reasoning skills, which allowed humans to constantly acquire and improve information. Our concern is with a reading of the history of cumulative technological culture that is based largely on modern experiments in simulated settings and less on phenomena crucial to the long-term dynamics of cultural evolution.

In this paper, I discuss the role of Anselm’s ontological argument in the philosophy of R.G. Collingwood. Anselm’s argument appears prominently in Collingwood’s Essay on Philosophical Method (1933) and Essay on Metaphysics (1940), as well as in his early work Speculum Mentis (1924). In the proof, Collingwood finds the central expression of the priority of “faith” in the first principles of thought to reason’s activities. For Collingwood, it is Anselm’s proof that clearly expresses this relationship between faith and reason. The (...) two elements of this analysis that must be understood if one is to understand Collingwood’s use of the proof are what he means by “the idea of an object that shall completely satisfy the demands of reason” and the “special case of metaphysical thinking.” I analyze both of these elements and conclude by showing how Anselm’s proof is essential to Collingwood’s historical science of mind.

The aesthetic techniques used in The Expanse are indicative of the infinite space that is an essential and ever‐present character in the show. The cinematography and set design of The Expanse make extensive use of chiaroscuro—a famous artistic technique in the history of painting. For some reason, the infinity of The Expanse attracts us. The look and design of the show indulges us in an experience of the sublime. The dynamically sublime is an experience of infinite power, but not where (...) our survival is threatened by it. The experience of the sublime is one proof of freedom. The absence of the ability to know the significance of what one does in the context of the infinite does not diminish the significance of what they do. The characters of The Expanse know this. They act because they know they must, and they have faith that what they do matters. (shrink)

The primary aim of this dissertation is an exegesis of Collingwood's historical science of mind. I take seriously Collingwood's claim that history is for "self-understanding" and treat his philosophy of history as a form of reflective philosophy. In particular, I examine the epistemological basis for Collingwood's claim that mind is an object that changes as it understands itself. ;In Chapter One, I consider the distinction between natural process and historical process as central to an understanding of Collingwood's historical science of (...) mind. I defend Collingwood's attempt to preserve the distinction between historical process and natural process in order to reserve for history its appropriate subject matter---mind. ;In Chapter Two, I consider the epistemological basis for Collingwood's claim that mind changes fundamentally in the historical process. I argue that Collingwood's reading of Anselm's proof of the existence of God is the key to understanding his theory of the priority of "faith" to reason and so to the historical nature of first principles. ;Chapter Three has two parts. In part one, I examine Collingwood's logic of philosophical concepts: the scale of forms. In part two, I argue Collingwood's moral philosophy, found in The New Leviathan and in his lectures on "Goodness, Rightness, Utility" , exemplifies this logic. I conclude that Collingwood's historical study of mind is an attempt to overcome the disjunction between theory and practice caused by the abstract thinking of modern scientific consciousness. ;Chapter Four provides a survey of the scholarship surrounding Collingwood's corpus as a whole. I argue that there have been three waves of Collingwood scholarship. The first is influenced by T. M. Knox's editing of Collingwood's manuscripts and his "radical conversion hypothesis." The second wave of Collingwood scholarship argues for the systematic or thematic unity of Collingwood's philosophy. The third and most recent wave builds on the second. As an example, I discuss Guiseppina D'Oro's suggestion that Collingwood's thought is unified by its overarching concern with critical philosophy. I conclude with the suggestion that Collingwood's thought is unified by an attempt to provide a viable reflective philosophy based on historical consciousness. (shrink)

This book is a collection of secondary essays on America's most important philosophic thinkers—statesmen, judges, writers, educators, and activists—from the colonial period to the present. Each essay is a comprehensive introduction to the thought of a noted American on the fundamental meaning of the American regime.

BACKGROUND: There is a need for interdisciplinary research to better understand how pedagogical approaches in primary physical education (PE) can support the linked development of physical, cognitive and affective aspects of physical literacy and physical activity behaviours in young children. The Skill Acquisition Methods fostering Physical Literacy in Early-Physical Education (SAMPLE-PE) study aims to examine the efficacy of two different pedagogies for PE, underpinned by theories of motor learning, to foster physical literacy, especially for children living in disadvantaged areas. METHODS: (...) SAMPLE-PE will be evaluated through a cluster-randomised controlled trial targeting 5-6 year old children from schools located in areas of high deprivation in Merseyside, North-West England. Schools will be randomly allocated to one of three conditions: Linear Pedagogy, Nonlinear Pedagogy or Control. Nonlinear and Linear Pedagogy intervention primary schools will receive a PE curriculum delivered by trained coaches over 15 weeks, while control schools will follow their usual practice. Data will be collected at baseline (T0), immediately post-intervention (T1) and six months after the intervention has finished (T2). Children’s movement competence is the primary outcome in this trial. Secondary outcomes include physical activity, perceived competence, motivation, executive functions, and self-regulation. An extensive process evaluation will also examine implementation factors such as intervention context, reach, dose, fidelity and acceptability. DISCUSSION: The SAMPLE-PE project will enable better understanding surrounding how to operationalise physical literacy through enrichment of PE practices in early PE. The study will provide robust scientific evidence regarding the efficacy of underpinning PE pedagogy with theories of motor learning to promote the development of physical literacy. (shrink)

The plot of Iphigenia in Tauris is usually thought to be Euripides' own invention. Its basic assumption can be found in Proclus' summary of the Cypria, viz. that a deer was substituted for Iphigenia during the sacrifice at Aulis and that she herself was removed to the land of the Tauri. Her later rescue by Orestes and Pylades, however, cannot be traced with probability to any work of art or literature earlier than Euripides' play. In this play, in which Orestes (...) recognizes and then saves the sister whom he had long thought dead, it is assumed that her replacement by a deer went unseen by those present at the sacrifice. The sequel which this assumption allowed Euripides to invent is original only in a limited sense, since it bears the imprint of several familiar story types. These types include the following: the murder of a kinsman is narrowly averted by a recognition; a reunion is followed by an intrigue; and a maiden is rescued. Each is used elsewhere by Euripides. The first two, for example, are found in Cresphontes, the second in Electra, and the third in Andromeda. Correspondences of this sort, based on plot patterns, will naturally gain in interest if it can be shown that they throw light on a play's meaning or on the process that led to its creation. The student of dramatic plots, however, soon discovers that analogies between them are easy to draw and can be quickly multiplied. (shrink)

While top-down descriptors have received much attention in explaining corruption, we develop a grassroots model to describe structural factors that may influence the emergence and spread of an individual’s (un)ethical behavior within organizations. We begin with a discussion of the economics justification of the benefits of competition, a rationale used by firms to adopt structural aides such as the ‹stacking’ practice that was implemented at Enron. We discuss and develop an individual-level theory of planned behavior, then extend it to the (...) dyadic level in an internally competitive organization, and finally extend the dyadic model to the social network. We apply social network theory to predict favorable and unfavorable conditions for the emergence and diffusion of an intraorganizational instance of unethical behavior and find that network conditions favoring the suppression of the emergence of unethical behavior also promote its diffusion. For illustrative purposes, we utilize examples from Enron’s internally competitive structure to embed our arguments in a real world context and bring reality to our theorizing. Implications for both researchers and managers are discussed. (shrink)

Niche construction is the process whereby organisms, through their activities and choices, modify their own and each other’s niches. By transforming natural-selection pressures, niche construction generates feedback in evolution at various different levels. Niche-constructing species play important ecological roles by creating habitats and resources used by other species and thereby affecting the flow of energy and matter through ecosystems—a process often referred to as “ecosystem engineering.” An important emphasis of niche construction theory (NCT) is that acquired characters play an evolutionary (...) role through transforming selective environments. This is particularly relevant to human evolution, where our species has engaged in extensive environmental modification through cultural practices. Humans can construct developmental environments that feed back to affect how individuals learn and develop and the diseases to which they are exposed. Here we provide an introduction to NCT and illustrate some of its more important implications for the human sciences. (shrink)

The relationship between unethical peer behavior and observers’ unethical behavior traditionally has been examined from a social learning perspective. We employ two additional theoretical lenses, social identity theory and social comparison theory, each of which offers additional insight into this relationship. Data from 600 undergraduate business students in two universities provide support for all the three perspectives, suggesting that unethical behavior is influenced by social learning, social identity, and social comparison processes. Implications for managers and future research are discussed.

The belief that primitive men lived like beasts and that civilisation developed out of these brutal origins is found in numerous ancient authors, both Greek and Latin. It forms part of certain theories about the beginnings of culture current in late antiquity. These are notoriously difficult to trace to their sources, but they already existed in some form in the fifth century b.c. One idea common to these theories is that of progress, and for this reason a fragment of Xenophanes (...) is sometimes cited as their remote prototype: ‘The gods did not reveal all things to men from the beginning; instead, by seeking, men discover what is better in time’. Mainly on the strength of this fragment, Ludwig Edelstein devoted the first chapter of his book The Idea of Progress in Classical Antiquity to Xenophanes, and W. K. C. Guthrie has even declared that there is good reason to attribute to him a fuller account of progress, one that would include details found in later authors who speak of the early life of mankind. One of these details is the statement that the life of primitive men was ‘brutal’ or ‘beastlike’ . In these authors the implication of that term varies from ‘unschooled in the basic crafts’ to ‘inhumanly violent and bloodthirsty’. In one sense or the other it is repeatedly encountered in ancient references to this subject. Accounts of primitive brutishness which make use of the word θηριώδης (or θηριωδς can be found in the Suppliants of Euripides, in the Hippocratic treatise On Ancient Medicine, in three passages of Diodorus, one of which is thought by some to contain Democritean doctrine, in four passages of Isocrates, in a fragment from a satyr-play Sisyphus which the ancient sources attribute variously to Euripides and to Critias, in a fragment of Athenion, in a second-century inscription, in Plutarch, in Tatian, in Themistius, and in a scholion to Euripides.

We are living in an algorithmic age where mathematics and computer science are coming together in powerful new ways to influence, shape and guide our behaviour and the governance of our societies. As these algorithmic governance structures proliferate, it is vital that we ensure their effectiveness and legitimacy. That is, we need to ensure that they are an effective means for achieving a legitimate policy goal that are also procedurally fair, open and unbiased. But how can we ensure that algorithmic (...) governance structures are both? This article shares the results of a collective intelligence workshop that addressed exactly this question. The workshop brought together a multidisciplinary group of scholars to consider barriers to legitimate and effective algorithmic governance and the research methods needed to address the nature and impact of specific barriers. An interactive management workshop technique was used to harness the collective intelligence of this multidisciplinary group. This method enabled participants to produce a framework and research agenda for those who are concerned about algorithmic governance. We outline this research agenda below, providing a detailed map of key research themes, questions and methods that our workshop felt ought to be pursued. This builds upon existing work on research agendas for critical algorithm studies in a unique way through the method of collective intelligence. (shrink)
