The literature on affective determinants of physical activity is growing rapidly. The present paper aims to provide greater clarity regarding the definition and distinctions among the various affect-related constructs that have been examined in relation to PA. Affective constructs are organized according to the Affect and Health Behavior Framework, including: affective response to PA; incidental affect; affect processing; and affectively charged motivational states. After defining each category of affective construct, we provide examples of relevant research showing how each construct may (...) relate to PA behavior. We conclude each section with a discussion of future directions for research. (shrink)

This manuscript overviews recent research on the intention-behavior gap, focusing on moderators of the intention-behavior relationship. The manuscript draws on the concept of intention strength to make two important points. First, strong intentions provide better predictions of behavior, thereby reducing the intention-behavior gap. However, strong intentions have the additional features of being more stable over time, less pliable in the face of interventions to change them, and more likely to bias information processing about engaging in the behavior. These four features (...) of intention strength are not independent. For example, stable intentions are likely to provide better predictions of behavior. Second, various predictors of strength may also constitute important, but little studied, moderators of the intention-behavior relationship. Moreover, the effects of these moderators of the intention-behavior relationship may be mediated through intention stability. Future research on the intention-behavior gap would benefit from a more systematic consideration of a broad range of moderators of the intention-behavior relationship both individually and in combination. In addition, future research could usefully explore how these moderating effects might be explained. Such a systematic approach may further our understanding of the intention-behavior gap in relation to physical activity and other behaviors. (shrink)

The conflict between courts and medicine is best shown in the mental health cases requiring judgment of whether a person should be confined, and whether they should be medicated or left free to decide for themselves. In such cases, deprivation of liberty for noncriminal offenders is at question, but if they are released, they may be exposed to injury or injure others. “Clear and convincing” evidence is hard to prove in such cases.The TOPOFF 2 terrorism preparedness exercise was two years (...) in planning, but the courts were involved only seven days before the exercise. Judge Murphy was put in charge of the Circuit Court building and was asked to stop all court proceedings to stop people from going into a building that might have been contaminated. (shrink)
