Understanding the Determinants of Consumer Composting Behavior1

This study compared 3 models of waste management behavior: (a) a theory of reasoned action model, (b) an environmental belief-behavior model, and (c) an integrated waste management model which is based on the theory of planned behavior. The three models were compared using data from a sample of over 1,400 individual respondents who each completed a survey and a 2-week diary of their consumer composting activities. Overall, the results suggest that while the environmental beliefs-behavior model and the integrated waste management models both fit the data well, the integrated waste management model provided better predictive power and offers significant insight into the factors that influence composting behavior.     

Religious Coping and Heart Transplantation: From Threat to Health

Previous research has established the existence of homogeneous religious coping profiles in cardiac-transplantation candidates labeled as the deferring/collaborators, self-directors, and the eclectic religious copers. However, their prospective impact on outcome has not yet been established. This paper examines potential differences between pre-cardiac transplantation religious coping cluster groups on post-cardiac transplantation quality of life (physical functioning, mental health, and general health). Results indicated that the religious coping profiles of deferring/collaborators and self-directors had significantly better scores on mental health and general health than did the eclectics. Implications for religious-coping research and clinical practice are discussed.     

Davidson on First-Person Authority

Davidson's explanation of first-person authority in utterance of sentences of the form 'I V that p ' derives first-person authority from the requirements of interpretation of speech. His account is committed to the view that utterance sentences are truth-bearers, that believing that p is a matter of holding true an utterance sentence, and that a speaker's knowledge of what he means gives him knowledge of what belief he expresses by his utterance. These claims are here faulted. His explanation of first-person authority by reference to the requirements of interpretability is committed to the view that all understanding involves interpretation. This is argued to be a misconception of understanding and of speaker's meaning. Davidson's account involves acceptance of the cognitive assumption that normally when a person V s that p , he knows that he does. This assumption is challenged. Throughout, Davidson's conception is compared and contrasted with Wittgenstein's.

The Belief in Good Luck Scale

The construction and properties of the Belief in Good Luck (BIGL) Scale are described. Three studies provide evidence that reliable individual differences exist with respect to beliefs about luck. Some individuals maintain an irrational view of luck as a somewhat stable force that tends to influence events in their own favor, while others seem to hold the more rational belief that luck is random and unreliable. Further, these beliefs showed a considerable amount of stability over time. The BIGL was significantly related to locus of control (primarily to a chance subscale), but other evidence suggested these constructs were distinct. Belief in good luck was not related to general optimism, academic pessimism, self-esteem, desire for control, or achievement motivation. There was also evidence that belief in good luck was distinct from feeling fortunate or generally satisfied with one's life. Ethnic group differences were observed for the BIGL scale, showing that Asian-Americans were more likely to endorse superstitious beliefs about luck than non-Asians. Finally, the BIGL scale was shown to predict positive expectations for the outcome of everyday situations that are typically associated with luck. This is generally in agreement with previous findings suggesting that people who believe in personal good luck react to lucky events by becoming more positive about the likelihood of future success (Darke & Freedman, 1997). In general, it is suggested that irrational beliefs about luck can serve as a source of positive expectations for the outcome of future events.     

Cerebral Anesthetization for Localization of Speech: The Contribution of W. James Gardner

In 1949, the neurologist Juhn Wada reported the first use of a new procedure for determining the localization of speech and language in neurological patients: examination of the effects on speech and language after injecting a barbiturate, sodium amytal, into the internal carotid artery of each hemisphere in succession. By the 1960s, Wada'sIntracarotid Amobarbital Procedure,orIAP,had become the method of choice for identifying the speech-dominant side in one kind of neurological patient, persons with epilepsy who are candidates for surgical resection, and it remains so today. In 1941, however, an American neurosurgeon, W. James Gardner, reported his use of a different anesthetization procedure for speech localization in neurological patients. Instead of injecting sodium amytal through the blood supply, as in the IAP, Gardner injected procaine hydrochloride directly into cortical tissue. In this paper, we provide a brief biography of Gardner. We then discuss his method of cortical anesthetization, the theoretical and empirical background guiding his use of this method and his choice of patients, and, finally, the fate of Gardner's method within the scientific community.     

Effects of Acute Stress or Centrally Injected Interleukin-1beta on Neuropeptide Expression in the Immune System

Acute stress stimulates the expression and release of corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP) from the hypothalamus, and the pro-opiomelanocortin products beta-endorphin and ACTH from the anterior pituitary. These neuropeptides are also expressed in immune tissues, and it has been proposed that they may modulate immune responses to stress through paracrine mechanisms. We subjected rats to restraint stress or central injection of interleukin (IL)-1beta to determine whether these acute stimuli can alter the expression of neuropeptides in the spleen and thymus. Restraint stress significantly increased the contents of all these neuropeptides in thymic, but not splenic, extracts. A single icv injection of IL-1beta increased contents of CRH, AVP, ACTH and beta-endorphin in the spleens of both sham-operated and adrenalectomised (ADX) rats. IL-1beta increased thymic contents of CRH and ACTH in sham-operated rats but these increases were not observed in ADX rats. These results suggest that the effects of IL-1beta on neuropeptide expression in the spleen are independent of glucocorticoids, whereas IL-1beta stimulation of neuropeptide expression in the thymus is dependent on circulating glucocorticoids. There were significant correlations between increases in CRH, ACTH and beta-endorphin in the spleen, and between CRH and ACTH in the thymus, consistent with the suggestion that IL-1beta-induced increases in ACTH and beta-endorphin may be mediated through CRH. These results provide evidence that stressors can directly influence neuropeptide expression in immune tissues. Thus stress may influence immune functions through paracrine mechanisms involving locally synthesised neuropeptides as well as through activation of the hypothalamo-pituitary-adrenal axis.
