Time, Self, and the Curiously Abstract Concept of Agency* 总被引:2,自引:0,他引:2
The term "agency" is quite slippery and is used differently depending on the epistemological roots and goals of scholars who employ it. Distressingly, the sociological literature on the concept rarely addresses relevant social psychological research. We take a social behaviorist approach to agency by suggesting that individual temporal orientations are underutilized in conceptualizing this core sociological concept. Different temporal foci—the actor's engaged response to situational circumstances—implicate different forms of agency. This article offers a theoretical model involving four analytical types of agency ("existential,""identity,""pragmatic," and "life course") that are often conflated across treatments of the topic. Each mode of agency overlaps with established social psychological literatures, most notably about the self, enabling scholars to anchor overly abstract treatments of agency within established research literatures. 相似文献

Summary. When evaluating potential interventions for cancer prevention, it is necessary to compare benefits and harms. With new study designs, new statistical approaches may be needed to facilitate this comparison. A case in point arose in a proposed genetic substudy of a randomized trial of tamoxifen versus placebo in asymptomatic women who were at high risk for breast cancer. Although the randomized trial showed that tamoxifen substantially reduced the risk of breast cancer, the harms from tamoxifen were serious and some were life threaten-ing. In hopes of finding a subset of women with inherited risk genes who derive greater bene-fits from tamoxifen, we proposed a nested case–control study to test some trial subjects for various genes and new statistical methods to extrapolate benefits and harms to the general population. An important design question is whether or not the study should target common low penetrance genes. Our calculations show that useful results are only likely with rare high penetrance genes. 相似文献

Prior corporate reputation, one responsibility of a public relations department, affects public perceptions toward corporate philanthropic messages and ultimately affects public attitudes toward the company. Using an experiment that emulates the sort of news consumption individuals normally undertake, participants inferred corporate charitable giving as a mutually beneficial activity when a company had a good reputation (H1a). Participants inferred corporate charitable giving as a self-interested activity when the company had a bad reputation (H1b). Also, public inference (suspicion) successfully mediated corporate prior reputation on public attitude toward the company (H2). Participants showed positive attitude toward the company when they inferred the company had an altruistic motive for charitable giving (H3a). However, participants showed negative attitude toward the company when they inferred the company had a self-interested motive for charitable giving (H3b). 相似文献

The conventional wisdom strongly suggests a health care provider food chain for the future: Primary care physicians (PCPs), principally family practitioners, on the top playing the lead role, distantly followed by specialists, with hospitals and other ancillary services even further down the line. Is this a reasonable expectation? Will PCPs dominate the new systems? Or will they be but one of many equally necessary components of these developing integrated health care delivery organizations? Looking at the various models now developing, it would seem that future integrated delivery systems will utilize both PCPs and specialists, but with strong augmentation from a diverse assortment of other health care professionals, including nonphysician providers, educators, and administrators. To separate the illusion of primary care dominance of the coming health care system from the likely reality, we should first determine what is driving the apparent present demand for primary care physicians. Next, we will examine the possible and probable reactions to that demand from an economic standpoint and from the points of view of both health care professionals and the public. Finally, we must try to picture how health care provider organizations of the future are likely to look and how they will integrate their health care professionals. 相似文献

Using relative utility curves to evaluate risk prediction 总被引:2,自引:0,他引:2

Summary. Because many medical decisions are based on risk prediction models that are constructed from medical history and results of tests, the evaluation of these prediction models is important. This paper makes five contributions to this evaluation: the relative utility curve which gauges the potential for better prediction in terms of utilities, without the need for a reference level for one utility, while providing a sensitivity analysis for misspecification of utilities, the relevant region, which is the set of values of prediction performance that are consistent with the recommended treatment status in the absence of prediction, the test threshold, which is the minimum number of tests that would be traded for a true positive prediction in order for the expected utility to be non-negative, the evaluation of two-stage predictions that reduce test costs and connections between various measures of performance of prediction. An application involving the risk of cardiovascular disease is discussed. 相似文献

This study revisited the old research question of whether or not maternal employment would adversely affect children's development. We reframed the question by asking how a mother's temporal employment demands might be linked to child development. We used longitudinal data from a sample of 340 white, lower- to middle-class, dual-earner families living in the rural Midwest of the United States. The data were obtained from questionnaires and videotaped observations, and were informed by the mother, the father, the adolescent child, and a trained observer. As predicted, we found a strong relationship between a mother's temporal employment demands and work-family conflict, which was significantly associated with her emotional distress. A husband's egalitarian gender ideology was found to reduce the mother's emotional distress. Maternal distress was then negatively associated with nurturant and involved parenting, which in turn predicted a reduction in the adolescent child's emotional and behavioral problems over time. 相似文献

Objective. Applying existing theories relating to investment risk, this article examines the effects of judicial strength and adherence to the rule of law on portfolio investment in the developing world. We aim to demonstrate that countries with higher levels of judicial strength and rule of law are more able to attract portfolio investment because they provide greater protection of property rights and a better risk environment for investors. Methods. Using time‐series data for 79 developing countries for the period 1996–2005, we employ panel‐corrected standard errors multivariate regressions to demonstrate that higher levels of judicial strength and rule of law are associated with higher levels of portfolio investment. Results. We find that a one standard deviation increase in overall judicial strength and rule of law results in more than a 50 percent increase in portfolio investment. In separate analyses, we show that a one standard deviation increase in specific measures of judicial independence, impartial courts, and protection of property rights leads to increases in portfolio investment ranging from 27 percent to 184 percent. Conclusion. Judicial strength and adherence to the rule of law are important determinants of portfolio investment in the developing world. 相似文献

This study draws data from the Family Life Project to examine parenting behaviors observed for 105 mothers and grandmothers raising an infant in rural low‐income multigenerational households. Multilevel models are used to examine the relationships between maternal age and psychological distress and parenting of the infant by both generations. The findings indicate that young maternal age is a risk factor for less sensitive parenting in the presence of other risks, including psychological distress. Further, young maternal age is associated with negative parenting behaviors by grandmothers only. Grandmothers and mothers displayed similar levels of negative intrusive parenting, but different factors were linked to the observed parenting of each generation. These findings contribute to understanding the benefits and risks of three‐generation households. 相似文献
