Scholars who study rap music have long expressed concerns that criticism of the genre is inextricably linked to stereotypes of young Black men in the United States. Yet minimal research has empirically examined how rap music is linked to race in ways that legitimize and maintain anti‐Black attitudes, particularly attitudes related to crime. This article reviews how scholars have typically challenged seemingly racialized concerns about rap music before surveying the handful of studies that empirically examine attitudes related to rap music, race, and crime. In so doing, this essay highlights a growing need for broader conceptualizations of race/ethnicity and social control.  相似文献

This paper has three objectives. The first goal is to summarize the literature on same‐sex families relating to the major life transitions of relationship formation, marriage, parenting, relationship dissolution, and old age. For the most part, this literature remains scant, with many areas completely ignored. Second, reasons why there is relatively little known about the life course of same‐sex families will be examined. In particular, we argue that the life course’s focus on marriage as a marker for transitions, including whether or not transitions are on or off time, works to exclude same‐sex families since they are not legally able to marry in most countries. The third objective is to explore if, and how, the family life course development perspective can be adapted or modified so that it can account for the diversity of both same and opposite‐sex families.  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

The degree to which risk perceptions are socially constructed versus the result of actual exposure to risk is highly contested; how risk exposure and risk perception influence policy attitudes is also poorly understood. We examine how personal exposure to risk factors impacts risk perceptions and policy support related to air pollution and climate change. Our selection of risk exposure variables is informed by the “mental models” literature, and we employ an array of variables to capture subjective risk perceptions using novel survey data. We find that exposure to risk does little to predict risk perception and has a small influence on policy support. Overall, our findings lend support to a constructionist understanding of risk perception and support for policies related to environmental risks.  相似文献

Attrition represents a significant obstacle to overcome in any longitudinal research project. It is, perhaps, most keenly felt when the data collected are from a qualitative study, since, unlike quantitative longitudinal research, weighting factors cannot be applied to ‘correct’ for any biases in the achieved sample and even a small number of ‘lost’ respondents can equate to a large percentage of the original sample. It is perhaps because of qualitative longitudinal research’s (QLR) reliance on, generally speaking, smaller samples that few have been able to shed much light on which re-contacting procedures are associated with achieving higher rates of retention. In this article, using data from a fifth sweep of a larger but particularly challenging cohort of 199 former probationers, we explore the strategies which helped us maintain high levels of retention in a QLR study. The article contains many practical suggestions which others planning or undertaking similar studies may find useful.  相似文献

Growth and internationalisation of the Chinese economy have reconfigured the global value chains of many commodities with important implications for industry and rural and regional development both in and outside China. This article analyses the chain for cashmere, all stages of which have gravitated to China, and the impacts on rural development, especially for herders in remote pastoral regions. Traditionally a high‐value product, cashmere has become increasingly generic and adulterated over the past decade. More formal and closer integration of Chinese actors into the global industry and re‐orienting policy from supply‐side intervention to the enforcement of standards would enhance the competitiveness of Chinese cashmere in international fibre markets.  相似文献

Eye-tracking was used to investigate whether gaze direction would influence the visual scanning of faces, when presented in the context of a full character, in different social settings, and with different task demands. Participants viewed individual computer agents against either a blank background or a bar scene setting, during both a free-viewing task and an attractiveness rating task for each character. Faces with a direct gaze were viewed longer than faces with an averted gaze regardless of body context, social settings, and task demands. Additionally, participants evaluated characters with a direct gaze as more attractive than characters with an averted gaze. These results, obtained with pictures of computer agents rather than real people, suggest that direct gaze is a powerful attention grabbing stimulus that is robust to background context or task demands.  相似文献

The ability of older adults to use a domestic appliance depends on their comprehension of the appliance's operation. This may depend on transfer of understanding from similar, more familiar technology. While this may assist their interaction with the new device, it may constrain the discovery of new functionality not represented in the familiar technology, and, thereby, constrain the discovery of advanced functionality. Older adults experience declining cognitive abilities associated with attention, perceptual encoding, and memory (cueing and recall). Designing appliances to extend cognitive abilities provides opportunity to prolong functional independence. Concepts from cognitive psychology, human factors, and gerontology are reviewed to explain age-related behavior towards technology to support innovative product development of technologies for older adults.  相似文献
