The purpose of this study that focused on African American high school girls was threefold. First, the relationship of sports participation and victimization was explored. Second, the impact of sports participation on self-esteem was assessed. Third, the role of self-esteem and its disaggregated components (social acceptance, competence, and self-confidence) as mediators of the relationship between sports participation and victimization was examined. In accordance with the sport protection hypothesis, it was hypothesized that sports participation would be related to enhanced self-esteem and reduce victimization. Results suggest that sports participation appears to have some relationship to lower rates of victimization. There was also support for our assertion that sports participation was related to enhanced self-esteem. Finally, overall self-esteem and, specifically, the individual component competence mediated the relationship between sports participation and victimization. 相似文献

Cognitive perspectives on gambling propose that biased thinking plays a significant role in sustaining gambling participation and, in vulnerable individuals, gambling problems. One prominent set of cognitive biases include illusions of control involving beliefs that it is possible to influence random gaming events. Sociologists have reported that (some) gamblers believe that it is possible to throw dice in different ways to achieve gaming outcomes (e.g., ‘dice-setting’ in craps). However, experimental demonstrations of these phenomena are lacking. Here, we asked regular gamblers to roll a computer-simulated, but fair, 6 sided die for monetary prizes. Gamblers allowed the die to roll for longer when attempting to win higher value bets, and when attempting to hit high winning numbers. This behaviour was exaggerated in gamblers motivated to keep gambling following the experience of almost-winning in gambling games. These results suggest that gambling cognitive biases find expression in the motor behaviour of rolling dice for monetary prizes, possibly reflecting embodied substrates. 相似文献

A community structure analysis compared community characteristics and coverage of detainee rights and Guantanamo Bay in leading newspapers in 28 major cities nationwide, sampling all relevant 250+ word articles from September 12, 2001, to September 11, 2012. The resulting 359 articles were coded for “prominence” and “direction,” then combined into a “Media Vector” score for each newspaper (range = .6034 to ?.2500). About four out of five (82%) newspapers supported detainee rights. Stakeholder and buffer clusters were important. Pearson correlations revealed that stakeholders (the proportions and concerns of which are expected to be reflected in media coverage) were significant, with percentage of Mainline Protestant (r = .550, p = .001) linked to favorable media coverage of detainee rights and percentage of age 65 and older (r = ?.321, p = .048) linked to unfavorable coverage. The buffer hypothesis (associating higher proportions of privileged groups with coverage receptive to human rights claims) was also confirmed, with percentage of college educated correlating with favorable coverage (r = .409, p = .015). Regression analysis yielded two significant variables—percentage Mainline Protestant, 33%, and percentage professional/technical occupational status (another “buffer” measure), 27%, totaling 59.9%, both linked to favorable coverage. Unexpectedly, the Midwest displayed more media support for detainee rights than any other region of the United States. 相似文献

Prior research has devoted considerable attention to the relationship between the racial and ethnic composition of jobs and various indicators of organizational attachment. Fewer studies, however, examine how workplace racial composition affects individuals’ experiences of racial discrimination or how these experiences impact workers’ organizational attachment. To address this lacuna, we first examine the effects of workplace racial composition on perceived racial and ethnic discrimination. Next, we examine whether perceived racial discrimination mediates the association between racial composition and organizational attachment observed in prior studies. Finally, we explore whether these relationships are similar (symmetric) or different (non-symmetric) for non-Whites and Whites. The analyses indicate: (1) working with predominately same-race coworkers tends to diminish perceptions of racial discrimination, (2) perceived racial discrimination mediates some of the effects of racial/ethnic composition on organizational attachment, and (3) some non-symmetric effects between non-Whites and Whites are found. We conclude with implications for future research. 相似文献

The way that nonprofits respond to funding uncertainty is crucial to their ability to meet goals and position themselves for future success. This article investigates how structural, managerial, and financial characteristics affect the adaptive tactics used by human service nonprofits during times of financial stress. These tactics include adding new programs, reducing programs or staff, expanding or starting joint programs, pursuing earned income, and expanding advocacy involvement. Using longitudinal data on human service nonprofits collected on either side of the 2002–2003 economic downtown, we find that larger size provides organizations with a unique ability to choose among different adaptive tactics, as larger size was significantly predictive of adding new programs, reducing programs, expanding advocacy, and pursuing earned income. Strategic planning was positively associated with innovative tactics such as starting joint programs or pursuing earned income. Financial stress or declines in an organization's major funding source led to cutbacks, as expected, but managers who foresaw these challenges were able to respond proactively by adding programs or starting joint programs. However, managers with more training did not respond much differently than did other managers, and organizational age and use of performance management tools had no effect in guiding organizational responses to financial uncertainty. 相似文献

Multivariate control charts are used to monitor stochastic processes for changes and unusual observations. Hotelling's T2 statistic is calculated for each new observation and an out‐of‐control signal is issued if it goes beyond the control limits. However, this classical approach becomes unreliable as the number of variables p approaches the number of observations n, and impossible when p exceeds n. In this paper, we devise an improvement to the monitoring procedure in high‐dimensional settings. We regularise the covariance matrix to estimate the baseline parameter and incorporate a leave‐one‐out re‐sampling approach to estimate the empirical distribution of future observations. An extensive simulation study demonstrates that the new method outperforms the classical Hotelling T2 approach in power, and maintains appropriate false positive rates. We demonstrate the utility of the method using a set of quality control samples collected to monitor a gas chromatography–mass spectrometry apparatus over a period of 67 days. 相似文献

This paper reports on the findings from a qualitative study into the experiences of parents who were involved in the English child protection system in 2013. Seventeen in‐depth interviews were conducted involving 19 parents and/or partners, and a framework approach was used to analyse the data. There were positive experiences of individual social workers and some positive experiences of the child protection system. However, the overwhelming theme of the parents' experiences was that the system was uncaring, inflexible and for some harmful to both themselves and their children. Despite being included in the child protection process, parents felt they were not afforded the same rights as a participant, as a decision‐maker or as a partner in seeking to improve the situation. The threat of consequences silenced parents who felt unable to speak out or challenge the things they disagreed with or coerced others into signing agreements they did not agree to. Such experiences related to a sense that they were being treated as ‘less than human’. These findings are considered within the context of recent reforms within the English child protection system. 相似文献

Adult death rates are a critical indicator of population health and well-being. Wealthy countries have high-quality vital registration systems, but poor countries lack this infrastructure and must rely on estimates that are often problematic. In this article, we introduce the network survival method, a new approach for estimating adult death rates. We derive the precise conditions under which it produces consistent and unbiased estimates. Further, we develop an analytical framework for sensitivity analysis. To assess the performance of the network survival method in a realistic setting, we conducted a nationally representative survey experiment in Rwanda (n = 4,669). Network survival estimates were similar to estimates from other methods, even though the network survival estimates were made with substantially smaller samples and are based entirely on data from Rwanda, with no need for model life tables or pooling of data from other countries. Our analytic results demonstrate that the network survival method has attractive properties, and our empirical results show that this method can be used in countries where reliable estimates of adult death rates are sorely needed. 相似文献
