Earlier work on the preparation of student teachers to deal with child protection concerns had indicated that initial teacher training (ITT) providers were often struggling to determine what to include on the subject and who should provide the input, as well as coping with the difficulty of trying to fit it into an overfull curriculum. In an attempt to support this work, the National Society for the Prevention of Cruelty to Children (NSPCC) developed a course for this group of students. Although an evaluation indicated the need for the materials to be redrafted, the views of both those involved in the exercise and a subsequent survey of ITT providers not only contributed to the redraft but also to the debate around the most effective approach to training professionals to protect children and young people.

Race relations and stratification literatures offer explicit expectations concerning interracial conflict. Causal arguments derived from these perspectives are examined in this study to explore their ability to explain interracial violence above and beyond criminological perspectives of economic deprivation and racial inequality. The vast majority of previous aggregate-level studies on violence are cross-sectional, ignoring the importance of a dynamic model that incorporates the influence of changing structural conditions in urban areas on interracial violence. We explore theories that incorporate dynamic explanations for the influence of structural factors related to crime as well as racial conflict and employ a methodological approach that models the change in structural conditions for rare events such as interracial homicide. We find that changes between 1980 and 1990 in urban Black and Hispanic population composition, racial competition and racial inequality differentially explain the variation in White and Black interracial homicide offending.  相似文献

This study reports on the incorporation of female officers into the Atlanta Bureau of Police Services which until recently had an all-male occupational subculture. Fieldwork techniques included one-year of participant observation and the structured interviewing of 50 police officers.Findings indicated that women have been acculturated into the behavior and attitudes characteristic of the male police group. Specifically, they express increased cynicism and distrust of the public, and their behavior is abrupt with an unsympathetic demeanor. Conversely, women police officers have not been accepted as equally capable as male police officers by the latter. This discriminatory reaction results in a male overprotective attitude which is expressed in male domination of both detective and uniformed officers' work. These findings are congruent with the data from other studies which examined occupations in which women were numerically rare (tokens).The author concludes that because females emulate the male officers' ethos and behavior, and because they have not been accepted as equals in the police group, they have not greatly changed the male subculture of policing.  相似文献

The purpose of this study was to explore the perceived adequacy of families' incomes and selected financial management practices (food budgetin debt, saving) in two Latin American countries. An interview survey was used to gather socioeconomic and demographic information from 537 families in Chile and Mexico. There were major differences between Chile and Mexico in the income adequacy responses and also major differences within countries between income levels. Implications of the findings for policy makers and curriculum planners who work in developing countries with inflationary conditions and income inadequacies are discussed.  相似文献

Experimental data were compiled for seven soybean varieties studied at four different locations in the U.S. for a period of one to three years. Three dose–response functions (linear, quadratic, and Weibull) were fitted, as appropriate, to the experimental data. Effects of acid deposition on soybean yields were estimated by combining variety-specific dose–response and production data. These calculations suggest that U.S. soybean production (2.2 billion bushels in 1982) would increase by 3.2 million bushels with a 10% reduction in 1982 hydrogen ion concentration levels in all counties where soybeans were grown, and by almost 70 million bushels with uniform improvement to pH 5.2. These estimates are based on many simplifying assumptions and are subject to several important sources of uncertainty explored in this study. The calculated changes are small in comparison with effects from other natural and anthropogenic stresses.  相似文献
