Men court-mandated to attend a batterer's intervention program (BIP) were evaluated to determine whether pre-BIP readiness to change and the presence of partner violence subtypes predicted BIP completion, criminal recidivism, and postadjudication partner violence 6 months post-BIP. Of the 199 subject sample, 40% did not complete BIP. Four readiness-to-change clusters were found, with most men (76%) reporting change-resistant stages-of-change profiles. The partner violence typology reported by Holtzworth-Munroe et al. (2000) was supported with clustering into four subtypes: family only (FO), low-level antisocial (LLA), borderline/dysphoric (BD), and generally violent/antisocial (GVA). BIP completion was predicted by violence subtype (with BD and GVA more likely to drop out) but not by pre-BIP readiness to change. Men rearrested scored higher on the precontemplative stage of change and were more likely to be in the BD and GVA subtypes. Implications for counseling strategies are discussed.  相似文献

We consider the problem of a retailer managing a category of vertically differentiated products. The retailer has to pay a fixed cost for each product included in the assortment and a variable cost per product sold. Quality levels, fixed, and variable costs are exogenously determined. Customers differ in their valuation of quality and choose the product (if any) that maximizes their utility. First, we consider a setting in which the selling prices are also fixed. We find that the optimal set of products to offer depends on the distribution of customer valuations and might include dominated products, that is, products which are less attractive than at least one other product, on every possible dimension. We develop an efficient algorithm to identify an optimal assortment. Second, we consider a setting in which the retailer also determines the selling prices. We show that in this case the optimal assortment does not include any dominated product and does not vary with the distribution of customer valuations when there is no fixed cost. We develop several efficient algorithms to identify an optimal assortment and optimally price the products. We also test the applicability of our methods with realistic data for two product categories.  相似文献

Community-based distribution (CBD) programs present an alternative way of effectively reaching people in rural areas of developing countries where conventional methods of delivery do not exist or fail. This paper reviews the experience and findings from the Jane Goodall Institute’s (JGI) TACARE program in the Kigoma region of Tanzania. It focuses on the family planning CBD program and its integration within the TACARE program to meet the broader mission of JGI’s conservation efforts. Both qualitative and survey data suggest that the CBD program meets the needs for contraception in participating rural communities and is a complementary and acceptable strategy to ultimately contribute to reduce population pressure on the villages around Gombe National Park.  相似文献

The South Carolina coastal zone is among the fastest growing areas in the U.S., and population epicenters are marked by dense brackish water pond (lagoon) coverage associated with housing complexes and golf courses. Surveillance efforts in 2001–2002 documented the widespread occurrence of several types of potentially or measurably toxic harmful algal blooms (HABs) in these ponds. These man-made retention ponds were constructed in order to serve as a buffer between developed areas and open estuaries or for aesthetic reasons. However, the combination of restricted tidal flow and nutrient and/or contaminant deposition creates a stimulatory environment for potential HAB formation. These discoveries introduce the need to consider mitigation measures to existing ponds and HAB preventive strategies for future pond construction.  相似文献

This study examines the influence of a selected set of determinants of contraceptive method switching in rural Sri Lanka. Of interest is the question of how change in contraceptive practice at the individual level can account for patterns observed at the aggregate level. Based on calendar data on contraceptive use over a 3-year period, collected for more than 3,000 married women in a 1986 survey, the multivariate analysis shows that women who attain all or a significant proportion of their desired fertility tend to switch to more effective methods. Women who experience method failure tend to switch methods, usually to a type that is more effective. The woman's background determinants of age and education have small but significant effects on method switching, whereas the effect of household economic well-being is not significant. There is strong indication that rural couples are practicing contraception in a nonrandom fashion, switching methods in accordance with changes in their fertility motivations and contraceptive experience.  相似文献

This study examines the attribution of responsibility for the problematic response to Hurricane Katrina in the fall of 2005. Based on social identity theory, the study compared the attribution with racism and non-racism factors (situational vs. dispositional attributions) between African American and European American students (n = 505). As hypothesized, African American identity was related to greater racism attribution, even after controlling for demographics, faith factors, and cognitive-emotional reactions to the hurricanes. European American identity was associated with more executive-responsibility attributions, but the effect vanished after adjusting other factors. The study underscores the importance of acknowledging group identity rather than an overarching American identity in exploring the race effect after a national collective trauma. The consequential implications for disaster planning, future research investigation, and social service delivery are discussed.  相似文献

This study examined the relationship between colleges' alcohol abuse prevention strategies and students' alcohol abuse and related problems. Alcohol prevention coordinators and first year students in 22 colleges reported whether their schools were implementing 48 strategies in six domains, and students (N = 2041) completed another survey concerning their use of alcohol and related consequences. Colleges were most likely to prevent alcohol use in public places on campus and the delivery and use of kegs. Four alcohol prevention domains were inversely associated with at least one of five outcomes related to student alcohol abuse or related consequences, and the alcohol policy and enforcement domain was inversely associated with all outcomes. Colleges should pay particular attention to strategies related to policy and enforcement.  相似文献

This study reports efforts to locate and survey participants in Project Northland Chicago (PNC), a longitudinal, group-randomized trial of an alcohol preventive intervention for racial/ethnic minority, urban, early-adolescents, 3-4 years following the end of the intervention. Data were collected annually among students from 6th-8th grade and then at age 17-18. Tracking procedures were used to maintain contact with participants and data collection consisted of three phases: (1) Internet- and mail-based surveys; (2) in-school survey administration; and (3) courier service delivery. Contact was lost with 11% of this urban cohort from the end of the PNC intervention activities through these longterm follow-up efforts, as indicated by returned locating postcards. Fifty-three percent of the cohort responded to the survey, the majority completing in Phase 1 of our data collection. Additional school-based and courier-delivery efforts increased our response rate by 11.5%. Costs per completed survey were $118 in Phase 1, $166 in Phase 2, and $440 in Phase 3. This study illustrates that it is possible to track and follow-up a high-risk cohort as they progress through adolescence, even with minimal efforts in intervening years. Lessons learned from this study may inform future efforts to track and collect longitudinal data among high-risk populations.  相似文献

Evidence that Muslims support patriarchal values more than non-Muslims is abundant but the nature of this evidence is contested. The ‘cultural’ interpretation suggests that patriarchal values are an inherent element of Muslim identity. The ‘structural’ interpretation holds that patriarchal values reside in structural characteristics and have little to do with Muslim identity. Evidence on these contradictory claims is inconclusive. Neither have advocates of the cultural position shown that Muslim support for patriarchal values remains robust under control of structural characteristics; nor have proponents of the structural position demonstrated that Muslim support for these values vanishes under such controls. Filling this gap, we use multi-level models to test whether Muslim support for patriarchal values vanishes under control of patriarchy's structural underpinnings. We find that Muslim support for patriarchal values is robust against various controls; and we identify mosque attendance as a mechanism to sustain Muslim support for patriarchy in non-Muslim societies. Yet, rising levels of education, labor market participation, and a glacial emancipative trend diminish Muslim support for patriarchy, especially among women.  相似文献
