The implications of the residential concentration of minority populations are issues of vital concern in the United States. Much of the previous minority concentration literature has focused on African-American residents of metropolitan communities. This article expands on this literature by exploring a variety of minority groups in nonmetropolitan communities. It was found that the minority residents of communities with large minority populations were in worse socioeconomic conditions than the minority residents of predominately white communities. Further, for most socioeconomic variables, it was found that as minority concentration increased, white residents tended to do better. In addition, the extent of racial inequality between minority and white residents was greater in communities with larger minority populations. Implications of the above findings are discussed.  相似文献

Abstract In recent years, the most pronounced change in the structure of American agriculture has been the increasing concentration of farm production. A human ecological perspective was used to generate hypotheses about the factors related to variations in farm concentration in U.S. counties. Analysis using the 1978 and 1987 Censuses of Agriculture revealed that concentration is greatest in counties with higher levels of agricultural intensity, greater use of mechanization, and greater use of farm labor.  相似文献

Hepatitis C virus (HCV) has reached epidemic proportions among drug users, and drug programs are in a unique position to provide each of their patients with HCV education. Using a nationwide sample (N = 434) of drug treatment programs, we report the results of a logistic regression analysis that differentiates programs providing HCV education to all of their patients versus programs that do not. Fifty-four percent of the programs provide HCV education to all of their patients. Programs are about four and a half times as likely to provide HCV education to all patients if they dispense methadone; almost four times as likely to provide this service if they educate most of their staff about HCV; twice as likely if they are residential; and almost twice as likely if they conduct HIV testing on-site. Our findings indicate that there is a need to increase HCV educational services in drug treatment programs.  相似文献

This paper outlines the career of Maurice F. Parmelee, sociologist, government official, nudist, and author of thirteen books, including the first American criminology text (1918). The contents of the latter are examined and contrasts with contemporary textbooks are noted. Parmelee's career is an anomoly, for although he published abundantly, he faded into sociological obscurity. Some conjecture is offered about scholarly career paths generally, drawn out of the Parmelee case. Finally, the paper argues that historical accounts of the development of American criminology are incomplete, for they fail to mention a number of early figures, including Parmelee.  相似文献

Few studies have evaluated how participation in violence that occurs on the streets as part of criminal or delinquent behavior relates to violence that occurs as part of dating or marital relationships (partner violence). Using longitudinal data from 141 African American and Latino male youth (15–19 years old), the relation between family characteristics and participation in one or both types of violent behavior was evaluated. The youth in this study were more likely to report use of violence in relationships if they were also participating in violence as part of other criminal behavior. However, there were distinct groups of offenders. Among those males reporting involvement in a dating or romantic relationship, four groups were identified: (1) those who had not participated in either type of violence, 57%; (2) those who had participated in partner violence only, 14%; (3) those who had participated in street violence only, 12%; and (4) those who had participated in both, 17%. Discriminate function analyses significantly differentiated the group who had participated in both types of violence from the nonviolent group, with the former group having poorer functioning families. These two groups were also differentiated from the partner violence‐only and street violence‐only groups. No differences were found between the partner violence‐only and the street violence‐only groups. Implications for intervention and prevention are discussed.  相似文献

The purpose of this study was to examine the acceptance of Global Positioning System (GPS) used to help people with dementia, who are at risk for wandering in their communities. We used a mixed methods research approach that included use logs, pre and post paper-based questionnaires, and focus groups. Forty-five client-caregiver pairs (dyads) were included to use one of the GPS devices for an average of 5.8 months over a 1-year period. GPS acceptance was high; dyads were likely to continue using the GPS. According to the participants, the GPS provided caregivers peace of mind and reduced anxiety in dyads when clients got lost.  相似文献

Even though widespread efforts have focused on educating young adults about HIV and AIDS, many individuals continue to engage in behaviors that place them at risk. These behaviors include frequent experimentation with alcohol and other drugs prior to sex, engaging in sexual activity with different partners, and inconsistent safe sex practices (Butcher et al. 1991). The combination of these risky behaviors causes increased concern about the spread of HIV among those of college age. This study focused on two behaviors by examining the relationship between substance use during adolescence and early initiation of sexual activity in a sample of 950 subjects aged 19–21 in a mid-sized southern city. Results indicate that early use of alcohol and marijuana relates to earlier initiation of sexual activity and subsequent risky sexual behavior among young adults. Also, gender differences were observed for frequent users of marijuana and alcohol with males engaging in riskier sexual practices. Recommendations for interventions are made.  相似文献
