Over the last two decades in the United States, mainstream environmental organizations have reduced, rather than increased, democratic participation by citizens in environmental problem-solving. The environmental justice movement, on the other hand, has served to enlarge the constituency of the environmental movement by incorporating poorer communities and oppressed people of color into environmental decision making process; build community capacity by developing campaigns and projects that address the common links between various social and environmental problems; and facilitate community empowerment by emphasizing grassroots organizing over advocacy. This paper outlines the different components in the environmental justice movement. It is our contention that if researchers and policymakers continue to conceive of the ecological crisis as a collection of unrelated problems, then it is possible that some combination of regulations, incentives, and technical innovations can keep pollution and resource destruction at tolerable levels for more affluent socioeconomic populations. However, poor working class communities and people of color which lack the political–economic resources to defend themselves will continue to suffer the worst abuses. However, if the interdependency of issues is emphasized as advocated by the environmental justice movement, then a transformative environmental politics can be invented.  相似文献

This study reports findings from an evaluation of a new generation jail in a large southwestern state. The jail is one component of a complex containing a traditional jail, an indirect supervision facility (barracks), and the new generation jail. Using survey and operational data, we compare the new generation jail to the other two facilities. The findings provide generally positive support for the effectiveness of the new generation jail. Inmates and staff were much more satisfied with the physical facilities. Staff perceived it as more secure, though they reported only limited advantages in safety and security. Violence and disciplinary problems were substantially lower. However, no savings in staffing levels were noted, nor were there differences in job satisfaction for staff in the new generation jail. We discuss the implications of the findings and suggest additional directions for jail evaluations.  相似文献

Three samples of college students were tested on Hogan's Survey of Ethical Attitudes (SEA) and Rest's Defining Issues Test (DIT), a test of moral reasoning ability in the Kohlbergian tradition. In addition, one of the samples took Collins's revision of Rotter's Internal-External Scale (I-E) while another sample took Snyder's Self-Monitoring Scale. There was a small but reliable tendency for subjects who endorsed the ethics of personal conscience, as measured by the SEA, to show greater maturity in moral reasoning, as assessed by the DIT. This result was seen as raising some interesting questions about the relation between liberalism-conservatism and moral maturity. The subjects who advocated the ethics of social responsibility tended to show more internal locus of control as measured by the I-E scale. There also was a tendency for subjects who preferred the morality of conventional role-conformity, as measured by the DIT, to have high scores on the Self-Monitoring Scale. The correlations between personal conscience and mature moral reasoning, while significant, were small enough to make it seem that people of various social and political attitudes are likely to achieve maturity in moral reasoning.Received his Ph.D. from Michigan State University in 1973.

The contraceptive behavior of adolescent girls was viewed from a decision-making perspective. A semistructured interview protocol was used in interviewing 120 girls aged 12–19 in three clinics (Teen Family Planning, Prenatal, Pediatric Acute Care) at Michael Reese Hospital and Medical Center on (1) demographic in formation; (2) sexual and obstetric history; (3) contraceptive and sexual knowledge, attitudes, and practices; (4) environmental pressures; (5) personality factors; and (6) decision-making style. We found that the girls were generally poor contraceptors. They viewed the costs of contraception (in terms of safety) to be high; and they positively valued physical intimacy, opportunities for which come up unexpectedly and sporadically. These factors, along with their ambivalent views toward pregnancy and childbearing seemed to encourage their risk-taking behavior. Once pregnancy occurred, it was carried to term because of the strong internal and external pressures they felt to have and keep the baby. The peer-led intervention program that we are developing based on the survey findings will focus on (1) the teenagers' lack of accurate and complete knowledge about birth control and conception, (2) their limited sense of options concerning birth control and pregnancy outcomes, and (3) their poor understanding of and lack of insight into what motivates their behavior.This study is part of the investigation being conducted by the YADMAC (Young Adult and Adolescent Decision Making About Contraception) Project at Michael Reese Hospital and Medical Center, 2959 South Cottage Grove, Chicago, Illinois 60616.

Two studies were undertaken to examine parental influences on autonomy and identity development. In Study 1, 262 adolescents in seventh and eleventh grades were given Kurtines's autonomy measure, Simmons's identity measure, and Elder's questions regarding the adolescents' perceptions of their parents' autocratic, democratic, or permissive parenting styles. Study 2 was a replication with 168 subjects. Across both studies it was found that sex-role socialization is more influential for automony development than is either level of parental power or age. Both age and father's use of democracy were the most influential variables on identity development.Received Ph.D. from the University of Minnesota.

This paper examines the linkage between crack market activity and gunhomicide suggested by Blumstein (1995), who argues that the arrival ofcrack stimulated an increased availability of guns among juveniles. Thisgreater availability of guns, the argument continues, is responsible for thesharp upswing in juvenile homicide experienced in the United States in themid-1980s. Using city-level data on crack arrests and gun-related juvenilehomicide, we fit a change-point version of the Bass (1969) model ofinnovation diffusion. We find that, in most large American cities, thediffusion process for crack cocaine experienced an onset of dramatic growththat was followed by a similar, slightly slower growth in gun homicidescommitted by juveniles. We further use cluster analysis to find that thespatial patterning of the two processes is similar, starting on the East andWest Coasts and working their way toward other regions of the nation. Gunuse in homicide among slightly older offenders (ages 18–24) alsoexperienced a change at roughly the same time as the juveniles, but the rateof diffusion was considerably milder than for the younger group; offendersages 25 or older generally show no growth in gun-related homicide whatsoever. In addition, there is no detectable surge in juvenile nongun homicide activity. Based on these findings, we conclude that the crack cocaine markets–gun availability linkage is highly plausible, and we suggest directions for future research in clarifying the dynamics of the late-1980s surge in juvenile homicide.  相似文献

Stable, enforceable property rights over resources normally furthers economic efficiency. I argue that stable rights to government created rents and wealth transfers, by contrast, generate inefficiency. Secure rights to receive transfers increases rent-seekers' incentive to make political investments creating new transfers. I demonstrate the point using a two period rent-seeking game. Contestable transfers reduce the probability of establishing a transfer program and aggregate rent-seeking expenditures. Strengthening transfer recipients' rights increases the difficulty of eliminating a transfer program.  相似文献

The death of a parent in childhood represents a profound psychological insult. Although a number of studies have examined rates of depression and anxiety in bereaved children, less attention has been given to understanding predictors of children's adjustment to the loss. Data are presented from 83 families with school-age children in which a parent had died of cancer in the preceding 18 months. The surviving parent and one randomly selected child completed individual interviews conducted by a clinician in the families' homes. Using multiple regression, potential predictors of children's psychosocial adjustment to parental death are examined and their relative importance is discussed. Among the predictors considered were child's age, child's gender, deceased parent's gender, time since death, length of illness, presence of siblings, and parental communication patterns. The child's perception of the surviving parent's level of openness in parental communication was found to be significantly correlated with lower levels of depressive symptoms and state anxiety in bereaved children. Boys reported lower levels of depressive symptoms than did girls, and older children reported lower levels of state anxiety than did younger children.  相似文献
