This article is about the history of logic in Australia. Douglas Gasking (1911?1994) undertook to translate the logical terminology of John Anderson (1893?1962) into that of Ludwig Wittgenstein's (1921) Tractatus. At the time Gilbert Ryle (1900?1976), and more recently David Armstrong, recommended the result to students; but it is reasonable to have misgivings about Gasking as a guide to either Anderson or Wittgenstein. The historical interest of the debate Gasking initiated is that it yielded surprisingly little information about Anderson's traditional (...) (syllogistic or Aristotelian) logic and its relation to classical (first-order predicate or Russellian) logic, the ostensible topic; but the materials now exist to interpret Anderson's logic in classical logic, possibly as an algebra of classes. This would be of little interest to contemporary logicians, but it might shed some light on Anderson's philosophy. (shrink)

This paper concerns the special ethical problems in child and adolescent psychiatry which relate to the child as a developing being. Two themes are discussed--the sense of responsibility in the child, and the therapist's responsibility towards the child. As a background to understanding the former, ideas on moral and cognitive development are reviewed. The therapist's responsibility is discussed in relation to different styles of therapy and the ethical issues they raise. The article concludes with a number of suggested ethical principles.

Adolescence methamphetamine use is an issue of considerable concern due to its correlation with later delinquency, divorce, unemployment and health problems. Understanding how adolescents initiate methamphetamine abuse is important in developing effective prevention programs. We formulate a mathematical model for the spread of methamphetamine abuse using nonlinear ordinary differential equations. It is assumed that susceptibles are recruited into methamphetamine use through imitation. An epidemic threshold value, Ra\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {R}}_a$$\end{document}, termed the abuse reproduction (...) number, is proposed and defined herein in the drug-using context. The model is shown to exhibit the phenomenon of backward bifurcation. This means that methamphetamine problems may persist in the population even if Ra\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {R}}_a$$\end{document} is less than one. Sensitivity analysis of Ra\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {R}}_a$$\end{document} was performed to determine the relative importance of different parameters in methamphetamine abuse initiation. The model is then fitted to data on methamphetamine users less than 20 years old reporting methamphetamine as their primary substance of abuse in the treatment centres of Cape Town and parameter values that give the best fit are chosen. Results show that the proportion of methamphetamine users less than 20 years old reporting methamphetamine as their primary substance of abuse will continue to decrease in Cape Town of South Africa. The results suggest that intervention programs targeted at reducing adolescence methamphetamine abuse, are positively impacting methamphetamine abuse. (shrink)

Domestic activities, involving productive and reproductive spheres, are mainly performed by women, requiring a great amount of knowledge and skills that are poorly represented in the literature and often undervalued in the society. Women’s role in the food system was investigated in Lacanjá Chansayab, Mexico, a village inhabited by ~ 400 Lacandon Maya people. This research included participant observation for three months in the community and semi-structured interviews with 10 cis-women and 5 cis-men documenting their recipes, the relationships that are (...) developed along their work in the food systems and actions for the restoration of traditional food. Women’s roles in food systems are central; they have an intricate knowledge of their environment and have principal roles in producing, obtaining, and transforming biodiversity into diverse meals within the kitchenspace. But they do more than producing, collecting, and mixing of ingredients. Their role in the food systems creates different types of relationships; the kitchenspace is a source of empowerment, traditional food is crucial for maintaining biocultural memory, and for establishing relationships with other-than-human beings. However, serving traditional foods is also a potential source for discrimination against their families even from members of their own community. It was recognized by participants that traditional food system is a medium for biocultural restoration in their community. Dignifying women’s work, views, techniques, and knowledge in traditional food systems is critical for food sovereignty, social justice, and biocultural restoration. (shrink)

There are many important methodological decisions that need to be made when examining emotional reactivity in psychopathology. In the present study, we examined the effects of two such decisions in an investigation of emotional reactivity in depression: (1) which (if any) comparison condition to employ; and (2) how to define change. Depressed (N = 69) and control (N = 37) participants viewed emotion-inducing film clips while subjective and facial responses were measured. Emotional reactivity was defined using no comparison condition (i.e., (...) raw scores), baseline comparison condition (i.e., no stimulus presented), and neutral comparison condition (i.e., neutral stimulus presented). Change in emotional reactivity was assessed using four analytic approaches: difference scores, percentage change, residualised change, and ANCOVA. Results differed among the three comparison conditions and among several of the analytic approaches. Overall, our investigation suggests that choosing a comparison condition and the definition of change can significantly influence the presence of group differences in emotional reactivity. Recommendations for studies of emotional reactivity in psychopathology are discussed. (shrink)

Leg rigidity is associated with frequent falls in people with Parkinson’s disease, suggesting a potential role in functional balance and gait impairments. Changes in the neural state due to secondary tasks, e.g., activation maneuvers, can exacerbate rigidity, possibly increasing the risk of falls. However, the subjective interpretation and coarse classification of the standard clinical rigidity scale has prohibited the systematic, objective assessment of resting and activated leg rigidity. The pendulum test is an objective diagnostic method that we hypothesized would be (...) sensitive enough to characterize resting and activated leg rigidity. We recorded kinematic data and electromyographic signals from rectus femoris and biceps femoris during the pendulum test in 15 individuals with PD, spanning a range of leg rigidity severity. From the recorded data of leg swing kinematics, we measured biomechanical outcomes including first swing excursion, first extension peak, number and duration of the oscillations, resting angle, relaxation index, maximum and minimum angular velocity. We examined associations between biomechanical outcomes and clinical leg rigidity score. We evaluated the effect of increasing rigidity through activation maneuvers on biomechanical outcomes. Finally, we assessed whether either biomechanical outcomes or changes in outcomes with activation were associated with a fall history. Our results suggest that the biomechanical assessment of the pendulum test can objectively quantify parkinsonian leg rigidity. We found that the presence of high rigidity during clinical exam significantly impacted biomechanical outcomes, i.e., first extension peak, number of oscillations, relaxation index, and maximum angular velocity. No differences in the effect of activation maneuvers between groups with clinically assessed low rigidity were observed, suggesting that activated rigidity may be independent of resting rigidity and should be scored as independent variables. Moreover, we found that fall history was more common among people whose rigidity was increased with a secondary task, as measured by biomechanical outcomes. We conclude that different mechanisms contributing to resting and activated rigidity may play an important yet unexplored functional role in balance impairments. The pendulum test may contribute to a better understanding of fundamental mechanisms underlying motor symptoms in PD, evaluating the efficacy of treatments, and predicting the risk of falls.

ABSTRACTEmotions are predicted to influence judgement and decision-making across a range of performance contexts. This experiment tested whether motivational-general arousal imagery can improve the decision-making performance of elite endurance cyclists. In total, 54 cyclists were assigned to either a positive imagery condition or a negative imagery condition. The cyclists were read one of two scripts designed to elicit positive or negative images during a 20-min maximal sustainable interval on a cycle ergometer. A decision-making task was performed before and immediately after (...) the maximal sustainable power interval. Results showed that the manipulation was successful with cyclists in the positive imagery condition reporting more positive affective states (higher levels of happiness and lower level... (shrink)

This book presents the framework for a new, comprehensive approach to cognitive science. The proposed paradigm, enaction, offers an alternative to cognitive science's classical, first-generation Computational Theory of Mind. _Enaction_, first articulated by Varela, Thompson, and Rosch in _The Embodied Mind_, breaks from CTM's formalisms of information processing and symbolic representations to view cognition as grounded in the sensorimotor dynamics of the interactions between a living organism and its environment. A living organism enacts the world it lives in; its embodied (...) action in the world constitutes its perception and thereby grounds its cognition. _Enaction_ offers a range of perspectives on this exciting new approach to embodied cognitive science. Some chapters offer manifestos for the enaction paradigm; others address specific areas of research, including artificial intelligence, developmental psychology, neuroscience, language, phenomenology, and culture and cognition. Three themes emerge as testimony to the originality and specificity of enaction as a paradigm: the relation between first-person lived experience and third-person natural science; the ambition to provide an encompassing framework applicable at levels from the cell to society; and the difficulties of reflexivity. Taken together, the chapters offer nothing less than the framework for a far-reaching renewal of cognitive science.

This article is concerned with developing a philosophical approach to a number of significant changes to academic publishing, and specifically the global journal knowledge system wrought by a range of new digital technologies that herald the third age of the journal as an electronic, interactive and mixed-media form of scientific communication. The paper emerges from an Editors' Collective, a small New Zealand-based organisation comprised of editors and reviewers of academic journals mostly in the fields of education and philosophy. The paper (...) is the result of a collective writing process. (shrink)

Context: Most constructivist discourse is situated at the philosophical-conceptual level, where arguments appeal to the intuition of the reader, while formal-computational models have only been taken into account to a very limited degree so far. Problem: Two types of problems need to be addressed: Synthetically, can constructivist concepts be turned into actual computational implementations? Can these be further conceptual developments in constructivist theory as such, or are they just an application thereof? Conceptually, does the notion of computation square with constructivist (...) approaches at all? Method: Paradigmatically, we discuss the meaning of “computational” in cognitive agents that comply with constructivist concepts. Also, we summarize the contributions. Results: From a constructivist point of view, the concept of “computational model” is ambiguous and depends on whether it is used in the sense of the computational(ist) theory of mind or simply as a tool. Implications: The insights presented in the contributions to this special issue point in the direction of a computational extension of constructivist approaches as well as a constructivist extension to computational approaches. However, while many of the questions we posed were discussed in the contributions and open peer commentaries, some of them were largely neglected and thus are subject to further discussion. (shrink)
