Theories and empirical evidence regarding prayer behavior generally emerge from studies of survey respondents in developed countries. The research we describe here adds to the literature by exploring links between demographic characteristics and the frequency and content of prayers for respondents in rural Tanzania. We surveyed 349 Christian households from six villages in the country's Kilimanjaro region. In some aspects our findings match results from survey research conducted elsewhere, and in other aspects our results differ from those commonly reported in the literature. We suggest that local cultural and socioeconomic conditions may account for the differences in outcomes. These results suggest a need for caution in applying to poor countries theories and expectations drawn from the developed country context.  相似文献

Quine made it conventional to portray the contradiction that destroyed Frege's logicism as some kind of act of God, a thunderbolt that descended from a clear blue sky. This portrayal suited the moral Quine was antecedently inclined to draw, that intuition is bankrupt, and that reliance on it must therefore be replaced by a pragmatic methodology. But the portrayal is grossly misleading, and Quine's moral simply false. In the person of others – Cantor, Dedekind, and Zermelo – intuition was working pretty well. It was in Frege that it suffered a local and temporary blindness. The question to ask, then, is not how Frege was overtaken by the contradiction, but how it is that he didn't see it coming. The paper offers one kind of answer to that question. Starting from the very close similarity between Frege's proof of infinity and the reasoning that leads to the contradiction, it asks: given his understanding of the first, why did Frege did not notice the second? The reason is traced, first, to a faulty generalization Frege made from the case of directions and parallel lines; and, through that, to Frege's having retained, and attempted incoherently to combine with his own, aspects of a pre‐Fregean understanding of the generality of logical principles.  相似文献

OBJECTIVE: Previous research (Webb, Simmons, & Brandon, 2005) suggested that smokers' reactions to self-help materials were more positive if they believed that the materials had been personally tailored to their individual characteristics and if they held expectancies that tailored interventions are superior to standard, or generic, interventions. The authors' objective in the current study was to replicate and extend this research by testing the efficacy expectancy priming before intervention delivery. DESIGN: In a 2 x 2 factorial experiment, 210 smokers (M = 23 cigarettes/day) recruited from the community (62% female; 92% Caucasian; mean age = 49) were randomly assigned to 1 of 4 conditions: placebo-tailored intervention/no priming, placebo-tailored intervention/priming, standard intervention/no priming, or standard intervention/priming. The tailoring-related expectancies of participants' in the priming conditions were primed before they were presented with the respective intervention booklets. MAIN OUTCOME MEASURES: Content evaluations, readiness to quit smoking, cessation self-efficacy, smoking-related knowledge, and progress toward quitting (behavior changes). Assessments occurred by mail at baseline and at 1-month postintervention. RESULTS: Similar to the earlier study, the placebo-tailored booklets produced superior evaluations and smoking-related cognitive and behavioral changes. Moreover, the pretreatment expectancy priming successfully altered participants' tailoring-related expectancies and also produced superior evaluations and outcomes. CONCLUSION: Findings support a causal role of tailoring-related expectancies on the efficacy of tailored interventions and suggest that interventions can be enhanced via expectancy priming.  相似文献

OBJECTIVE: People tend to overestimate the impact that future events will have on their quality of life. In the case of a medical treatment like kidney transplant, this should result in biased predictions--overestimates of how much the transplant will benefit quality of life. The authors surveyed kidney transplant patients, both before and after transplant, to test whether they would overestimate the benefits of a successful transplant for their quality of life. DESIGN: The authors interviewed 307 patients on a waiting list for cadaveric renal or renal-pancreatic transplant, and 195 patients one year after a successful transplant. A sub sample of patients were interviewed both before and after transplant. MAIN OUTCOME MEASURES: The survey included measures of quality of life, both in terms of an overall estimate (0-100), and across sub domains, including health, employment, and travel. RESULTS: Cross-sectional results suggested that overall quality of life improved after transplant, but the predictions of pretransplant patients overestimated the magnitude of the improvement (p < .01). In addition, patients predicted large improvements in specific life domains that did not change. These results were confirmed in longitudinal, prospective analyses. Additional analyses showed that posttransplant patients recalled their pretransplant quality of life to be much lower than what they had reported at the time. CONCLUSION: Consistent with an impact bias, patients substantially overestimated the benefits of a successful kidney transplant, both in terms of predictions of life after treatment, and in their memories of QOL before the transplant.  相似文献

People can differ tremendously in the emotions they experience, both in general as well as in response to specific events, and such differences have large impact on their lives. Based on recent research on individual differences in appraisal and emotion, we propose a framework to understand the basis for individual differences in emotional experience. In this framework, individual differences in how people appraise their circumstances and in how these appraisals are related to emotional experience are seen as crucial in determining how people differ in both contextualized emotional experience and more stable emotional dispositions. We discuss parallels with other explanatory frameworks, implications for the nature of emotion traits, and directions for future research.  相似文献

Abstract: The central concern of this paper is the nature of the relation between words on the one hand and their occurrences on the other. I argue here that while Kaplan's “common currency” conception of words is immune to much of the criticism to which Cappelen has subjected it, it runs afoul of the role words play in communication. And I sketch an alternative conception – the type‐continuant model – which shares the virtues but avoids the vices of Kaplan's conception.  相似文献
