Studies of involuntary outpatient commitment (OPC) among persons with severe mental illness have concluded that OPC is only effective in improving treatment outcomes when it is sustained for 6 months or longer and is combined with frequent outpatient services. This article explores factors that influence the delivery of outpatient services to subjects in a randomized trial of OPC and finds 2 general patterns. Outpatient visits were more frequent among all subjects with apparent clinical need, regardless of study assignment, and among subjects whose OPC was sustained beyond an initial court order. These results suggest that, in practice, sustained OPC represents a consensual agreement between clinicians and the court to more intensively address the complex needs of persons with severe and persistent mental illness. 相似文献

The United States prison population is becoming more diverse and comprised of increasingly more violent inmates. Although race has been cited as a risk factor for inmate violence, most prior research had narrowly investigated White/Black differences in inmate misconduct. Using a sample of 1,005 inmates from the southwestern U.S., the current study explored racial, ethnic, and citizenship correlates among male and female prisoners. Negative binomial regression models indicated that net of controls, Hispanics and Native Americans were the most violent male prisoners, while African Americans and Native Americans were the most violent female inmates. The current study was admittedly modest in scope; however, the findings were couched within a broader, imperative sociological framework that lamented the increasing interplay between communities and prison and the role of prison as a social institution. 相似文献

Our inquiry is the first phase of a project designed to explore systematically whether individuals are becoming more equipped to play a central role in world affairs. It hypothesizes that individuals have undergone a skill revolution, leading them to be more analytically competent, emotionally capable, and politically effective in assessing events, developing alternatives, and executing effective political action. The first phase is confined to the skills of elites: we tested the predicted generational changes by analyzing the skills of three types of individuals—elected officials in the U.S. Congress, witnesses at congressional hearings, and contributors to the daily press in three countries—in two widely separated epochs as they evaluated events across three issue areas—foreign affairs, international trade, and human rights. In doing so we randomly selected nearly one thousand paragraph-sized statements and coded them according to the methodology prescribed by the Integrative Complexity Coding Manual. All in all, our findings supported the hypothesis: the skill level of the sampled individuals was found to have increased over several generations by a statistically significant (P < .001) average greater than 10 percent. Each issue area also showed gains in the same direction between the two epochs and across all types of elites; and all of these results also met the 95 percent confidence level for statistical significance. Inasmuch as this finding does not negate the possibility of a long-term trend toward more capable publics, it points to the need for further research into the dynamics whereby world politics may become increasingly sensitive to demands at the micro level. 相似文献

How do differences in the implementation of regulation impact market behavior? I propose a theoretical framework to understand this impact as part of the process of embedding market participants through the institutionalization of legal consciousness within a field of action. I use this framework to understand the impact of the difference in the implementation of securities regulation in Ghana and Fiji. In Fiji, where the regulatory agency is more present and process‐oriented, brokers operate with a greater orientation toward formal rules. In Ghana, where the regulatory agency is distant and auditing, brokers rely on explicit enforcement of floor‐based norms. Conceiving of legal consciousness as an emergent feature of a field of social action advances the understanding of how legality is institutionalized, since the emergent structure shapes the orientations, behavior, and relations of actors within the field. 相似文献

Encouraging Tax Compliance With Positive Incentives: A Conceptual Framework and Research Directions*
Drawing on learning and social psychological research, we identify the processes by which positive incentives induce compliance with regulatory laws, using tax as a specific example. We evaluate the likely effects of various positive incentives on four different dimensions of compliance decisions: instrumental consequences, normative considerations, internalized motivation, and allegiance to authority. Linking incentives specifically to compliant behavior invokes a cost/benefit analysis, lowers intrinsic motivation and allegiance to authority, and requires authorities to monitor citizens and to distinguish between compliant and noncompliant behaviors. The alternative is to present the incentives as an attempt by the enforcement authorities to cooperate with the citizens. This method is less likely to invoke cost/benefit calculations; requires less intervention by authorities; and increases intrinsic motivation, consideration of normative issues, and allegiance to authorities. Prior research suggests that respectful treatment and praise may be more effective incentives for inducing long-lasting compliance than are materialistic incentives because people have a strong tendency to reciprocate actions they receive from authorities. Our analysis leads to proposals for program implementation and evaluation and raises some theoretical questions that need additional research. 相似文献

The child protection mediation or case conference–implemented under the new Child, Family, and Community Services Act–is a mandatory conference in British Columbia that attempts to provide a plan of care for the apprehended child or children through a combined cooperative effort of parents, social workers, their respective counsel, parties that have an interest in the child's welfare, and the mediation judge. It is also a process that undertakes to counter the adversarial effects of trial where the potential for conflict is great and seeks to achieve the spirit of building solutions through cooperation for the continued care of the child. A year later, the results look encouraging, as two thirds of cases settle and, in British Columbia, unlike any other province, the case conference is made available in every community where court is held. 相似文献

Peer influence is regarded as one of the strongest determinants of juvenile delinquency and particularly adolescent substance use. A commonly held view is that social pressure from friends to use drugs and alcohol is a major contributor to substance use. Yet the notion of peer pressure, implied by the association between peer-group associations and drug behavior, is seldom tested empirically. As a crucial test of the group pressure model, this research examines the role of peer pressure in mediating the effect of differential association on individual use. Moreover, few studies examine the nature of the relationship between peers and substance use as it relates to the processes leading toand from use. Drawing on differential association and social learning theories, our research specifies the social processes (socialization, group pressure, social selection, and rationalization) which dictate particular causal pathways leading to and from substance use and then estimates the reciprocal influences among differential association, social pressure from peers, attitudes favorable toward substance use, and individual use. Using the 1977–1979 National Youth Survey panel data, we estimate a covariance structural equation model allowing for correlated measurement error. In the cross-sectional analyses, we find no main effects of overt peer pressure on substance use. Estimation of the reciprocal effects model also reveals that overt peer pressure does not significantly influence substance use and does not mediate the effect of differential association. Instead, the influences of socialization, social selection, and rationalization play significant roles in understanding substance use.An earlier version of this paper was presented at the 1994 American Society of Criminology meetings in Miami, Florida. 相似文献
