Racist violence which occurred in Liverpool in 1919 is analyzed in this article, and it is argued that three main themes can be identified in media, policing and political debates which followed. These are fears of sexual relations between different ‘races’, competition for employment, and questions relating to citizenship occasioned by a scheme of assisted repatriation introduced to remove black migrant workers from the ‘mother country’. The article argues that the issue of ‘racial’ difference between the communities involved in the disorders should not be treated as a straightforward variable in its own right. Instead recognition of the articulation between racialised discourse and other factors, such as sexual relations, is central to a full understanding of the events. 相似文献

A method for combining forecasts may or may not account for dependence and differing precision among forecasts. In this article we test a variety of such methods in the context of combining forecasts of GNP from four major econometric models. The methods include one in which forecasting errors are jointly normally distributed and several variants of this model as well as some simpler procedures and a Bayesian approach with a prior distribution based on exchangeability of forecasters. The results indicate that a simple average, the normal model with an independence assumption, and the Bayesian model perform better than the other approaches that are studied here. 相似文献

The study describes an evaluation of a 48‐week physical activity and nutritional education programme for overweight/obese school‐age children using quantitative and qualitative methods. The majority of participants were obese or severely obese when enrolled, and while some improvements in body mass index, self‐esteem and engagement in a range of physical activities were noted, difficulties in evaluating a complex community‐based intervention were highlighted. Children, parents and health professionals described a range of benefits from attending the programme but more intensive services are likely to be needed for the most seriously obese children and for those families resisting intervention. 相似文献

Peleg (1978) presents a necessary and sufficient condition for the non-emptiness of the core, by considering quota games.
The purpose of this paper is to present a similar result for the non-emptiness of another solution concept introduced by Rubinstein
(1980) and called the stability set.

Abstract By way of introduction to this special issue on rural masculinities, we provide an overview of masculinity studies, emphasizing the influential work of Robert W. Connell on hegemonic masculinity. We go on to distinguish between two main avenues of rural inquiry in masculinity studies: studies of the masculine in the rural and studies of the rural in the masculine, or what we also term the masculine rural and the rural masculine. We apply this distinction to the six contributions to this special issue, showing how most of the papers maintain a kind of dialogue between the two. We conclude by arguing that studies of rural masculinities are a contribution rather than an alternative to feminist scholarship in the rural social sciences, and that the topic of rural masculinities provides rural scholarship with opportunities for conducting research in other disciplines. 相似文献

Abstract A two-phase study was conducted on the relationship between organizational climate variables and burnout among personnel in a multifunction community service agency. Initial interviews with a small pilot sample identified major sources of stress, which were then incorporated into a second-phase questionnaire to all staff. Multiple regression analyses illustrated that perceived interactions between head office administrators and sections of the agency contributed significantly to emotional exhaustion, whereas perceptions of within-section interactions and involvement in decision-making had a positive impact on personal accomplishment. Perceived communication levels, however, were negatively related to personal accomplishment. The findings suggest the importance of organizational variables and highlight strategies for burnout reduction and effective stress management in human service organizations. 相似文献

Abstract Objective: Researchers who study the etiology of college drinking typically employ measures of alcohol-use behaviors as outcomes; however, relatively little is known about the properties of alcohol-related problems (AP). This study aims to develop a single continuous measure of AP. Participants: The sample included 531 undergraduate college students who were surveyed in March 2007. Methods: The Rasch model was employed for dichotomous variables to analyze the measurement properties of 17 AP items. Results: Although issues with respect to differentiation at low levels of problem severity were identified, based on most strategies, the Rasch-based scale was shown to be a valid and reliable measure of AP among college students. Conclusions: Although there may be some need for slight modification and adjustment in the future, the AP scale developed here can potentially serve as a useful measure for etiological and prevention research. 相似文献

How people leave a devastated area after a disaster is critical to understanding their ability to cope with risks they face while evacuating. Knowledge of their needs for communications about these risks is particularly crucial in planning for emergency responses. A convenience sample of 1,444 persons who survived the World Trade Center (WTC) attacks on September 11, 2001 were surveyed to ascertain their initial and ultimate destinations once they had left the buildings, how they arrived there, the role of types of obstacles they encountered, and the need for information and the seeking of other people as potential factors in influencing the process of leaving immediately. This survey was part of a larger, original survey. Results showed differences in how people traveled by mode to initial and ultimate destinations, how immediately they left the area, and factors associated with when they left. How they traveled and when they left were associated with where people lived, their tendency in times of stress to seek out other people including who they knew in the immediate area (e.g., co‐workers or friends), the physical conditions surrounding them, and the importance to some of waiting for more information. Many people indicated they did not leave immediately because they had no information about where to go or what services would be available to them. Perceptions and communications about risks they were facing were reflected in the choices they considered in how and when to leave the area. These findings have numerous ramifications for understanding and guiding personal behavior in catastrophic situations. 相似文献
