On the heels of recent police shootings of an unarmed Michael Brown in Ferguson, Missouri, Walter Scott in North Charleston, South Carolina, and the death of Freddy Gray in Baltimore, Maryland, that stoked racial tensions, this article examines how beliefs about race and racial inequality influence whites’ attitudes toward the use of force by the police since the mid‐1980s. Our main dependent measure is a composite index (“Police Force Index”) constructed from four survey items from the 1986–2012 National Opinion Research Center's General Social Survey (GSS). Results show that (1) beliefs about race do indeed significantly predict whites’ attitudes toward police use of force, and more importantly, (2) this effect has remained constant since the mid‐1980s. We discuss theoretical and practical implications of these findings and suggestions for future research.  相似文献

We adopt a Bayesian approach to forecast the penetration of a new product into a market. We incorporate prior information from an existing product and/or management judgments into the data analysis. The penetration curve is assumed to be a nondecreasing function of time and may be under shape constraints. Markov-chain Monte Carlo methods are proposed and used to compute the Bayesian forecasts. An example on forecasting the penetration of color television using the information from black-and-white television is provided. The models considered can also be used to address the general bioassay and reliability stress-testing problems.  相似文献

This study advances understanding of environmental inequality by examining its production through the interaction of two ubiquitous and ongoing urban-ecological processes: industrial land-use changes and changing patterns of residential segregation. We employ longitudinal data from the Rhode Island Directory of Manufacturers (1953–2012) and tract-level US Census data measured at four panel-years (1980, 1990, 2000, and 2010) to study the effects of these interactions in Rhode Island’s historical industrial cities of Providence, Pawtucket, and Central Falls. Spatial patterning analysis and hybrid spatial panel modeling of residential exposure to active and legacy industrial sites in relation to ongoing racial and industrial change reveal two novel findings. First, we find a “legacy effect,” suggesting that the spatial organization of industrial activities prior to the study period has measurable impacts on patterns of residential segregation in later decades. Our results also indicate that over the study period Latinx and African-American residents have become increasingly less likely to bear disproportionate impacts of active manufacturing sites, despite very different spatial patterns of population growth. This is strong evidence that environmental inequality formation is a variable process in which historically distinct pathways can lead to similarly disproportionate exposure to environmental risk.  相似文献

This article examines the unspoken rules, routines, and rituals of the swimming pool, using ideas from negotiated order theory, Foucault, Goffman's dramaturgical theory, and symbolic interactionism. It identifies three sets of social norms: respect for personal space, respect for individuals' disciplinary regimes, and the desexualization of encounters. I show how these rules are (normally) followed or (occasionally) breached through various rituals, and examine the consequences for interaction order. The tale of “The Emperor's New Clothes” is used analogously to explain why actors cannot consciously attend to their precarious construction of reality, yet remain poised to defend it.  相似文献

In particular research domains, the randomized control trial (RCT) is considered to be the only means for obtaining reliable estimates of the true impact of an intervention. However, an RCT design would often not be considered ethical, politically feasible, or appropriate for evaluating the impact of many policy, programme, or structural changes common in public health research. As such, researchers must use alternative yet robust research methods for determining the impact of such interventions. The evaluation of natural experiments (i.e. an intervention not controlled or manipulated by researchers), using various experimental and non-experimental design options can provide an alternative to the RCT. The following review highlights (a) the importance of evaluating natural experiments; (b) design considerations associated with evaluating natural experiments; (c) methods for reducing bias in natural experimental studies; and (d) the potential benefits of targeted systems to enable natural experiments in emerging priority domains moving forward.  相似文献

This paper joins earlier interactionist projects in advocating for an analytical attentiveness to generic social process (GSP). This dynamic form of theorizing is indebted to the thought of Herbert Blumer and the extended phenomenological and pragmatist traditions. Rather centrally, the study of GSPs draws upon the foundational concepts of duration, intersubjectivity, and the self. Such concepts have contributed to some of symbolic interactionism's most enduring, empirically grounded and theoretically robust work. Drawing on a series of ethnographic research projects, this paper offers a research agenda for engaging GSPs transcontextually. Specifically, I argue for extending the study of GSPs through the examination of management in everyday life, the creation of subcultural value, and the social construction of doubt.  相似文献

Competition can foster misconduct in any circumstance where the organizer of a contest cannot perfectly monitor contestants' actions or when doing so is prohibitively costly. Although misconduct comprises all actions that are contrary to the interest of the organizer, it is not necessarily the case that it is optimal to prohibit all such behavior. In this paper, we determine the equilibrium level of misconduct chosen by players in a symmetric rank‐order tournament between two competitors in which the organizer tolerates some level of misconduct. In addition to showing that zero tolerance may not minimize the level of misconduct in equilibrium, we show that there exists a range of tolerated misconduct where a symmetric mixed strategy equilibrium exists with players cheating (i.e., misconduct above the tolerated level) with some probability. When the gain from misconduct is uncertain and unknown the contest organizer faces a tradeoff: tolerating more misconduct will reduce such behavior when the state of temptation is high, but increase it when temptation is low.

The continuity of social competence between 36 months and first grade was examined in a sample of children at risk due to prenatal exposure to cocaine (N = 92). Parent report data on social competence were collected at 36 months of age and both parent and teacher report data were collected when children were in first grade. Regression analyses indicated that 36-month social competence significantly predicted first-grade parent ratings of social competence, even after controlling for cognitive ability. Thirty-six month social competence also predicted first-grade teacher ratings of competence, but these relations were mediated by child gender and cognitive ability. Early social competence was also a significant predictor of first-grade language ability, after controlling for 36-month language. These findings emphasize the importance of early social competence for later development.  相似文献
