This research investigated differences in prevalence of depressive symptoms among adolescents from diverse ethnocultural groups. Data from a national survey of persons 12–17 years of age (n=2200) were analyzed, comparing symptom levels of Anglo, African, Mexican, and other Hispanic Americans using a 12-item version of the Center for Epidemiologic Studies Depression Scale. Overall, the results indicate differences in rates of depression. Females reported more symptoms of depression than males in every ethnic group. Among the ethnic groups, Mexican American males reported more depressive symptoms than other males and the same was true for Mexican American females, although to a lesser extent. Logistic regression of three different caseness scores (16+, 21+, 31+), adjusting for age, gender, perceived health, and occupation of the primary wage earner in the household, indicated that only Mexican American adolescents reported more depressive symptoms than the Anglo majority. The relative risk ranged from 1.46 to 1.83.Supported in part by grants MH44214 and MH44773 from the National Institute of Mental Health, by the Hogg Foundation for Mental Health, and by the Center for Cross-Cultural Research.Holds an M.A. and a Ph.D. in sociology and social psychology from the University of Kentucky at Lexington.

An objective, composite index of impulsivity, made up of three measures of reactivity to color on the Rorschach and amount of discrepancy between performance and verbal IQ on the Wechsler Scales, is proposed. It was predicted that impulsiveness as measured by this index would be associated with self-perception of impulsivity. Moreover, it was predicted that impulsiveness, whether objectively or subjectively measured, would tend to be associated with a history of greater and more frequent delinquency. The major hypotheses were confirmed. In addition, the data suggested that delinquents from higher socioeconomic levels may be more impulsive than their lower class counterparts. Additional work on refining and validating the impulsivity index is indicated.This work has been supported by Grant No. A70-15 from the Illinois Law Enforcement Commission.Currently a Ph.D. Candidate in Human Development at the University of Chicago.

The Eurasian Economic Union (EAEU) appeared in January 2015 as the latest and most ambitious attempt at reconnecting the post-Soviet space. Building on the Customs Union between Belarus, Russia, and Kazakhstan (2010), and successfully extending membership to Armenia and Kyrgyzstan (2015), the EAEU not only connects a market of over 182 million people, but has the stated aim of utilizing European Union experience to achieve deep integration in a fraction of the time. Based on original fieldwork conducted in Armenia, Belarus, Kazakhstan, and Russia, this article examines the kind of integration project currently under construction, as well as the EAEU’s ability to make a significant impact in the region. As argued, despite early achievements, the EAEU is very much limited to reproducing sovereignty rather than transforming it, marking a clear disconnect between rhetoric and reality. Moreover, when viewed from the perspective of the three “I”s – institutions, identity, and international context – even this modest reality faces significant barriers.  相似文献

This work reviews the hazards and risks of practicing forensic anthropology in North America, with a focus on pathogens encountered through contact with unpreserved human remains. Since the publication of Galloway and Snodgrass' seminal paper concerning the hazards of forensic anthropology, research has provided new information about known pathogen hazards, and regulating authorities have updated recommendations for the recognition and treatment of several infections. Additionally, forensic anthropology has gained popularity, exposing an increased number of students and practitioners to these hazards. Current data suggest many occupational exposures to blood or body fluids go unreported, especially among students, highlighting the need for this discussion. For each pathogen and associated disease, this work addresses important history, reviews routes of exposure, provides an overview of symptoms and treatments, lists decontamination procedures, and presents data on postmortem viability. Personal protection and laboratory guidelines should be established and enforced in conjunction with the consideration of these data.  相似文献

In Kenya, as in many developing countries, centralized control over water resources was implemented to improve agricultural productivity. By the 1980s, however, Kenya's postindependence policies of bureaucratic control were in disarray, and conflicts over water use were common. More recently, Kenya has embarked on a series of reforms that create a polycentric approach to water governance, in which decision making about water resources is shared among multiple, overlapping local, regional, and national authorities. Drawing on archival and field research, we examine these reforms in their historic context and argue that whereas centralized control was poorly adapted to the Kenyan context, polycentric governance is better suited to Kenya's variable social and ecological conditions and the available resources of its administrative agencies.  相似文献

More than two decades ago, Marmarou published a valid model for producing diffuse axonal injury (DAI) in rats. Since then, both mild and severe injuries have been obtained by researchers using the original method and a weight of 450 g. However, the diffuse brain injuries produced in rats were only similar to those seen in humans when the rats sustained severe brain injuries. In these cases, rat mortality in the original article was around 50%, and the cause of death was prolonged apnea post-impact. Rat survival after impact is critical for studying the progression of DAI. In order to explain the cause of death in human victims with cranial trauma who do not show gross brain injury, testing for the presence of DAI is essential. Thus, in order to minimize local and cervical injuries to increase rat survival, attention should be paid to the following aspects: a wider head protector disc should be used, the head of the rat should be elevated at the time of impact, and the foam bed should be soft enough to allow the movement caused by acceleration. With our modified method, rat survival increased by 30% compared to the original model (80% versus 50%). Moreover, 85.7% of rats demonstrated DAI after 24 h of survival. With these modifications, injuries appear in the same locations as in humans; thus, the method is suitable for the study of traumatic DAI in humans.  相似文献

This study characterized the specific offenses for which homeless individuals are arrested and incarcerated. Data were gathered from 581 homeless adults across 6 Oklahoma City shelters. Participants were asked to self-report incarceration history, nights spent in jails and prisons, and the offenses for which they were arrested. Overall, 76% of the sample had ever been arrested. Fifty-seven percent of the sample had been to jail more than 3 times in their lifetime and 13% had ever intentionally been arrested. The most prevalent type of arrest was drug possession (35%), followed by driving under the influence (31%) and disorderly conduct or public drunkenness (28%). Violent arrests, such as assault, robbery, domestic violence, murder, and rape, were the least prevalent type of arrest. In summary, offenses were largely drug and status offenses. These offenses may be prevented through increased substance use treatment accessibility and availability of housing. Policies to increase employment and housing for homeless adults regardless of criminal history should be expanded to reduce the occurrence of justice involvement.  相似文献

Native American (NA) youth's delinquency is one of the major problems that have been overlooked by criminal justice researchers and practitioners. To examine if negative family environment influences their delinquency with the mediating effect of negative emotion, this study analyzed structural equation modeling based on the General Strain Theory (GST). Using data regarding NA adolescents, this study found much evidence supporting GST. The results of the model with anger showed that anger was a mediating variable between family indifferences and delinquency, and the model with depression indicated that family indifferences increased delinquency through depression. However, some results in the model with anger and depression were not in accordance with GST hypothesis.  相似文献
