The purpose of this evaluation was to determine if client characteristics affected selected program outcomes. The sample consisted
of 475 clients admitted into a for-profit, private alternative probation and counseling program between November 1, 1998 and
February 28, 1999. Multiple regression analyses identified race, previous alcohol and drug treatment, and employment status
as significant predictor variables of client compliance. Being able to target client characteristics that are associated with
successful program outcomes can help programs fulfill their goals of diversion and costeffectiveness, thus making the most
effective use of scarce resources. 相似文献

A simple, robust, quasi-linear, structural general equilibrium rational voting model indicates turnout by voters motivated by the possibility of deciding the outcome is bell-curved in the ex-post winning margin and inversely proportional to electorate size. Applying this model to a large set of union certification elections, which often end in ties, yields exacting, lucid tests of the theory. Voter turnout is strongly related to election closeness, but not in the way predicted by the theory. Thus this relation is generated by some other mechanism, which is indeterminate, as no existing theory explains the nonlinear patterns of turnout in the data. 相似文献

Despite a growing emphasis by aid agencies on local participation and consultation, the recipients of aid commonly have mixed, if not hostile, responses to relief assistance. Agencies need to acknowledge the inequalities that are inherent in an aid relationship, and be more judicious in determining their proper role. The author calls for aid providers and recipients to accept our innate human equality and our circumstantial inequality in order to establish relationships of mutual respect and contemporaneous enjoyment of each other. 相似文献

This article uses empirical evidence from Nicaragua to examine Guillermo O'Donnell's argument that new democracies often become undemocratic delegative democracies and that vertical accountability is not enough to stop such encroaching authoritarianism. While events in the last five years have focused attention on illegal executive behavior by former president Alemán, Nicaragua's democracy actually has experienced authoritarian presidencies under all the major parties. Elections and popular mobilization have strengthened the independence of the legislature, however. Mechanisms of vertical accountability thereby have proven more effective than expected in restraining executive authoritarianism and fostering institutions of horizontal accountability. The case of Nicaragua shows that citizens can use the power balance and separate institutional mandate of presidential democracy to limit authoritarianism. 相似文献

Research indicates that children are at risk for delinquency if they live in a single-parent family and if they live in areas with high levels of family disruption. Although there is a substantial amount of research on both the individual and aggregate relationships, examining delinquency at either of these two levels alone is not appropriate. Specifically, families do not exist in isolation as individual-level research inherently assumes, and aggregate research is concerned with explaining rates of delinquency as opposed to explaining influences on individual behavior. The current research used data from thirty-five schools, an important adolescent context, to determine the individual- and school-level effects of single-parent families on delinquency. The results from an overdispersed Poisson HLM regression model suggest both individual and aggregate effects, with a potential buffering effect of intact families regardless of any adolescents' specific family structure. 相似文献

This study examined the relationship between social role playing and moral judgment development. Subjects were 197 students enrolled in introductory social science courses at a public junior/community college in a metropolitan area in southeast Florida. The 78 males and 119 females ranged in age from 17 to 66 years, with a mean age of 22. Rest's (1979a, 1979b) Defining Issues Test (DIT) was used to measure level of moral judgment. Social role playing was measured by the number of separate roles held by subjects in the past or present. Academic aptitude, socioeconomic status, age, and sex were included as control variables. Academic aptitude, age, and social role playing each had significant zero-order correlations with moral judgment, and social role playing added significantly to the explanation of moral judgment, controlling for academic aptitude and age. Implications of these results for the understanding of the development of moral judgment and for intervention programs are discussed. 相似文献
