The role of self‐determination in the relationship between social support and physical activity intentions

Using the hierarchical model of intrinsic and extrinsic motivation (HMIEM) and self‐determination theory as theoretical frameworks, the purpose of the present study was to assess the role of motivation‐related variables in the relationship between perceptions of social support and intentions to be physically active. Undergraduate students completed surveys assessing perceptions of social support, psychological needs satisfaction, self‐determination, and future exercise intentions. Model fit with the data was examined and was considered acceptable, indicating that social support was positively related to the satisfaction of psychological needs, which, in turn, was related positively to self‐determination and then to physical activity intentions.     

Moral nature of the DSM-IV Cluster B personality disorders

Moral considerations do not appear to play a large role in discussions of the DSM-IV personality disorders and debates about their empirical validity. Yet philosophical analysis reveals that the Cluster B personality disorders, in particular, may in fact be moral rather than clinical conditions. This finding has serious consequences for how they should be treated and by whom.     

Appreciation and emotion: theoretical reflections on the MacArthur Treatment Competence Study

When emotions are mentioned in the literature on mental competence, it is generally because they are thought to influence competence negatively; that is, they are thought to impede or compromise the cognitive capacities that are taken to underlie competence. The purpose of the present discussion is to explore the possibility that emotions might play a more positive role in the determination of competence. Using the MacArthur Treatment Competence Study as an example, it is argued that appreciation, a central theoretical concept in many contemporary approaches to competence, has important emotive components that are seldom sufficiently recognized or acknowledged. If true, this means that some leading contemporary accounts of competence need to be revised in order to make more adequate provision for the positive contribution of emotion.     

Telemedicine in Primary Health: The Virtual Doctor Project Zambia

Physician-researchers are bound by professional obligations stemming from both the role of the physician and the role of the researcher. Currently, the dominant models for understanding the relationship between physician-researchers' clinical duties and research duties fit into three categories: the similarity position, the difference position and the middle ground. The law may be said to offer a fourth "model" that is independent from these three categories. These models frame the expectations placed upon physician-researchers by colleagues, regulators, patients and research participants. This paper examines the extent to which the data from semi-structured interviews with 30 physician-researchers at three major pediatric hospitals in Canada reflect these traditional models. It seeks to determine the extent to which existing models align with the described lived experience of the pediatric physician-researchers interviewed. Ultimately, we find that although some physician-researchers make references to something like the weak version of the similarity position, the pediatric-researchers interviewed in this study did not describe their dual roles in a way that tightly mirrors any of the existing theoretical frameworks. We thus conclude that either physician-researchers are in need of better training regarding the nature of the accountability relationships that flow from their dual roles or that models setting out these roles and relationships must be altered to better reflect what we can reasonably expect of physician-researchers in a real-world environment.     

Feeling and representing: Computational theory and the modularity of affect

In this paper I review some leading developments in the empirical theory of affect. I argue that (1) affect is a distinct perceptual representation governed system, and (2) that there are significant modular factors in affect. The paper concludes with the observation thatfeeler (affective perceptual system) may be a natural kind within cognitive science. The main purpose of the paper is to explore some hitherto unappreciated connections between the theory of affect and the computational theory of mind.
