The Theory of Planned Behavior as a model for understanding sedentary behavior

ObjectivesSedentary time has emerged as an independent risk factor for numerous adverse health outcomes. However, little is known about the social-cognitive correlates of sedentary behavior. The purpose of this study was to provide preliminary evidence for the factor structure and composition of sedentary derived Theory of Planned Behavior (TPB) constructs and to determine the utility of these constructs in predicting sedentary intention and sedentary time.MethodTwenty-three items were created to assess attitudes, subjective norms (SN), perceived behavioral control (PBC), and intention with respect to time spent being sedentary. Using a web-based survey, 372 adults completed a modified Sedentary Behavior Questionnaire and were then randomised to one of three TPB questionnaire packages: general, weekday, and weekend. Weekday and weekend participants completed items for work/school (less-volitional) and leisure/recreation (volitional) activities separately, resulting in five TPB models being analyzed: general, weekday work/school, weekday leisure/recreation, weekend work/school, and weekend leisure/recreation.ResultsIrrespective of model, items grouped into coherent factors consistent with TPB and explained 9–58% and 8–43% of the variance in intention and behavior, respectively. The strongest and most consistent predictor of intention and behavior were SN and intentions, respectively. Mediation analyses indicated that attitudes consistently affected sedentary time through intention.ConclusionsThere is growing evidence that the TPB is a useful framework for understanding sedentarism.

KNOWLEDGE,VALUES, AND BELIEFS IN THE SOUTH AFRICAN CONTEXT SINCE 1948: AN OVERVIEW

In this contribution, an overview of the distinct ways in which the interplay between knowledge, values, and beliefs took shape in the South African context since 1948 is offered. This is framed against the background of the paleontological significance of South Africa and an appreciation of indigenous knowledge systems, but also of the ideological distortion of knowledge and education during the apartheid era through the legacy of neo‐Calvinism. The overview includes references to discourse on human rationality (as an implicit critique against ideology), on the use of social sciences in theological reflection, on the teaching of evolution in public schools, on science and religion, and on religion and ecology. The essay concludes with a survey of some of the major voices regarding the interface between religion and science in South Africa.     

Relativized common knowledge for dynamic epistemic logic

Relativized common knowledge is a generalization of common knowledge proposed for public announcement logic by treating knowledge update as relativization. Among other things relativized common knowledge, unlike standard common knowledge, allows reduction axioms for the public announcement operators. Public announcement logic can be seen as one of the simplest special cases of action model logic (AML). However, so far no notion of relativized common knowledge has been proposed for AML in general. That is what we do in this paper. We propose a notion of action model relativized common knowledge for action model logic, and study expressive power and complete axiomatizations of resulting logics. Along the way we fill some gaps in existing expressivity results for standard relativized common knowledge.     

Carers’ beliefs about counselling: a community participatory study in Wales

This interpretivist community participatory study explores carers’ beliefs about the potential usefulness of counselling in relation to the caring role. Twenty semi-structured interviews with carers were transcribed and analysed thematically. All participants thought counselling could potentially be helpful to carers, but their ideas about the ways in which it would help varied according to whether or not they had personal experience of counselling. Only carers with counselling experience had an awareness of counselling as focussing on changing feelings, thoughts, attitudes and behaviours. The implications of the findings for the provision of counselling services are discussed.     

Knowledge and availability

The mentioning of error-possibilities makes us less likely to ascribe knowledge. This paper offers a novel psychological account of this data. The account appeals to “subadditivity,” a well-known psychological tendency to judge possibilities as more likely when they are disjunctively described.     

A Confucian in Buddhist clothing? – Interpreting Nishida’s conception of the good as a realisation of the Mandate of Heaven

ABSTRACT

In this study, I examine the Confucian influence upon An Inquiry into the Good, the first publication of Nishida Kitarō. Nishida’s student Kōsaka Masaaki depicts his mentor’s conception of the good in terms of realising the 'Mandate of Heaven'. Taking this to be indicative of the importance of Confucianism for Nishida’s early thought, I compare his philosophy of pure experience and ethical project of ‘self-realisation’ with corresponding ideas found in the Confucian corpus. I especially focus on the Great Learning and Doctrine of the Mean as interpreted by the Neo-Confucian Wang Yang-Ming. This study builds upon the pioneering work of Michel Dalissier, Dermott Walsh and David Williams on the Kyoto School and Confucianism. My portrayal of Confucianism is indebted to the ‘philosophical’ translations of Roger Ames, David Hall and Henry Rosemont, Jr., which bring into relief the tradition’s ‘relational ontology’ that Graham Parkes teaches is shared by the Kyoto School.     

The Effects of Differing Knowledge Transfer Strategies on Group Decision Making and Performance

Encouraging reflection on one's existing knowledge in a group setting increases shared understanding, makes information available for problem solving, and makes it easier for members to show and to be shown the merit of others' preferences. However, it is also possible that attempting to constrain the process by which problem solvers manage this reflection process may prevent them from effectively tailoring their approach to different problems. The current research focuses on how the nature of different knowledge transfer strategies impacts problem solving processes and outcomes by examining manipulations of, or constraints to, problem solvers' approach to knowledge transfer. Participants were directed to generate associated knowledge in preparation for answering a series of estimation items, either in a group or individually. We found that groups using a shared reflection process (as opposed to reflecting at an individual member level) were able to give more weight to the inputs of their more expert members and that groups outperformed individuals. We discuss the process of promoting knowledge transfer in a group context relative to an individual context and relate this to the concept of task demonstrability.

Casuistic Reasoning in Expert Narratives on Healthy Eating

Individualisation of healthy eating is a broad tendency in Western culture and is becoming a popular ideal in nutrition science. Public perception of dietary knowledge is central to this individualisation and many experts now aim to present dietary knowledge in a way which relates to individual experience, as well as a casuistic style in which particular cases are discussed in relation to general, universal principles. Analysis of casuistic narrative styles in the public communication about healthy eating by experts makes explicit their flexible use of both particular cases and universal claims, in which clinical and personal cases are narratively employed by the experts to invite readers to personally consider dietary knowledge. Such casuistic narration by experts relates human agency and particular bodies to universal concepts in a way that has generative and critical functions with respect to dietary knowledge and understanding. The public articulation of clinical narratives by experts make salient the intersubjective emergence and accumulation of dietary knowledge between expert reasoning and lay understanding. Personal narratives have an essential role in presenting casuistic reasoning through experts’ personal lives and making their own bodies relevant to public communication about healthy eating. This emphasises the experts’ personal agency in relationship to common norms and general knowledge. Furthermore, both clinical and personal narratives are used by experts in their assessment of the shortcomings in public health messages. Experts’ casuistic narration thus does not merely construct credibility but has epistemic functions in constructing dietary knowledge tangible with respect to actual eating practices.
