The present study measured the existence of traumatic stress symptomatology as reported by certified law enforcement officers within the State of Delaware. A questionnaire was devised which documented age, sex, race, education, years of service, marital status, children, rank, position, and shift work. The questionnaire was divided into parts which assessed the exposure and the frequency of specific traumatic incidents experienced in the line of duty, and the frequency of experienced traumatic symptomatology criteria: re-experiencing, numbing, and arousal.  相似文献

This paper reports results of a study based on a nationally representative sample of U.S. youth (N = 11,549) that asked two questions: (1) How does family structure affect the likelihood of adolescent death beyond that of race/ethnicity, sex, socioeconomic status, personal behavior, and other structural factors and (2) under what conditions might appeals for social justice be warranted for relative mortality statuses and for absolute gains in mortality? The study found that marital instability increases the likelihood of dying when controlling for a variety of other factors including class, race/ethnicity, sex, and unemployment rate in area of residence. The author argues that this finding lends support to social justice arguments to redistribute resources in such a way as to ensure the likelihood of absolute gains in mortality. The study also found, however, that race/ethnicity/sex also accounted for the likelihood of dying independently of family structure when controlling for socioeconomic and other factors. The author argues that this finding lends support to social justice arguments to redistribute resources on the basis of relative mortality statuses.  相似文献

The American Law Institute proposes that in contested physical custody cases the court should allocate to each parent a proportion of the child's time that approximates the proportion of time each has spent performing caretaking functions in the past. Examined through the lens of child development research, the approximation rule is unlikely to improve on the best interests standard. It is difficult to apply; is perceived as gender‐biased; creates a new focus for disputing parents; renders a poor estimate of parents’ contributions to their child's best interests; overlooks parents’ intangible, yet significant, contributions to their child's well‐being; and miscalculates the essence of how a child experiences the family. A preferable alternative is a better defined, contemporary best interests standard that accommodates new knowledge and reforms that encourage nonadversarial, individualized resolutions of custody disputes.  相似文献

This article explores the influence that state finance has had on the Romanian party system by examining the entry and exit of parties throughout the period of 1990 – 2004 and focusing on the number of parties that gained representation in the parliament as well as the party incumbency rate. I find that state finance has had a limited influence on the party system as a whole but has been influential for specific parties. I argue that the influence of state finance partly depends on when the system was introduced. In developing party systems, the influence of state finance on individual parties is more differential.  相似文献

The economics of the Holocaust is a many‐facetted subject that is an integral part of the Holocaust's history. This paper describes some of the results of the new research since 1990 and discusses the economic rationalities employed by the perpetrators in despoiling the Jews. Economic considerations accompanied the timing and pace of the expropriation of Jewish assets and their “Aryanization.” The new research also shows that there was widespread collaboration in the expropriation of the Jews by private interests both inside Germany and in German‐controlled Europe and that networks of bureaucrats and private interests joined to achieve Nazi goals. The combination of expropriation and mass murder was one of the aspects of the Holocaust that made it unique.  相似文献

This article tests cross-nationally the minority group threat thesis that public sentiments toward repressive crime-control policies reflect conflicted racial and ethnic relations. Using multiple data sets representing France, Belgium, the Netherlands, East and West Germany, Italy, Luxembourg, Denmark, Great Britain, Greece, Spain, Finland, Sweden, Austria, Canada, Ireland, and Portugal, we examine whether racial and ethnic intolerance—animus, resentments, or negative sentiments toward minorities—predicts greater support for the death penalty. Our results reveal that the respondents were significantly more likely to express support for capital punishment if they were racially or ethnically intolerant while controlling for other covariates of public opinion. These findings indicate that the link between support for capital punishment and racial and ethnic animus may occur universally in countries with conflicted racial and ethnic relations.  相似文献
