Traffic related mortality in a red squirrel (Sciurus vulgaris) population receiving supplemental feeding

This paper presents data on red squirrel road casualties recorded in the four-year period 1993–1996 within the National Trust reserve and adjacent suburban gardens of Formby, Lancashire, England. A total of 130 adults and six subadults were recorded as road traffic victims. Road casualties accounted for 65% of the recorded adult mortality (26.7% of the reserve total and 88% in the suburban habitat). Adult males were killed more frequently than females during the winter months. Road traffic deaths were highly seasonal with a clear peak in the autumn months (53.7% of all casualties). It is suggested that this may be related to seasonal variation in foraging behavior and to the abundance of natural and supplemental foods.     

Disarming the War of the Growth Machines: A Panel Study

Intercommunity variation in growth machine activities, including the manipulation of the business climate and vertical integration with state economic development programs, net migration, and land use change are examined using a sample of 96 small urban places. A panel design and key informant methodology, 1970–90, permit cross-sectional and longitudinal observation. Using regression analysis with appropriate statistical controls, the research indicates that growth machines, particularly those in affluent communities, do intensify land uses. The business climate also negatively affects changes in business and industrial land uses as well as net migration. Some local efforts may not affect growth until the subsequent decade. The research suggests that growth machine activities are intensifying and may be exacerbating social inequality between places, especially affluent residential communities and declining working-class communities in the old industrial belt.     

Another Look at Accuracy and Confidence in Social Judgments

This study examined the relationship between accuracy and confidence on the Interpersonal Perception Task (IPT-15). This version of the IPT contains 15 brief, real-life scenes on videotape for which there are objectively correct answers to questions about status, intimacy, kinship, competition, and deception. A total of 241 participants were run in a 2 (high vs. low cognitive demand) × 2 (first impression vs. nonverbal cues strategy) × 2 (sex of participant) design. Overall, no significant relationship was found when accuracy scores were correlated with two between-participant measures of confidence. There was, however, a significant relationship within-participants between accuracy and confidence. Thus, participants' rated confidence for each of the 15 scenes did predict accuracy in judgments about the scenes. In addition, a 2 × 2 × 2 ANOVA on participants' transformed accuracy-confidence correlations revealed a small, significant effect of strategy. Specifically, the accuracy-confidence correlations were higher when participants were instructed to attend to specific nonverbal cues in making their judgments than when they were told to rely on their first impressions. Although there were no differences between men and women in either their accuracy or their accuracy-confidence correlations, men rated their confidence significantly higher than did women. The factors affecting the accuracy-confidence relationship and their role in automatic judgments are discussed.     

Does Family Structure Really Influence Educational Attainment?

This paper examines the effects of family structure on educational attainment after controlling for common family influences, observed and unobserved, using data from siblings. The use of sibling data permits us to examine whether the apparent effects of family structure are due to unmeasured characteristics of families that are common to siblings. The data come from pairs of siblings in the National Longitudinal Survey of Youth, 1979–1992. The results suggest that taking into account the unmeasured family characteristics yields estimates of the effects of family structure on educational attainment that are smaller, but still statistically significant, than estimates based on analyses that do not take unmeasured family influences into account.     

A Response to Xiao's “Necessary and Sufficient Conditions of Unacceptable Solutions in LP Discriminant Analysis”: Something is Amiss

Characterization of unacceptable solutions of linear programming methods for linear discriminant problems have been studied by many researchers. This note shows that a recent correction was not a correction but a tightening of prior results.     

A national evaluation of Safe Schools/Healthy Students: outcomes and influences

The Safe Schools/Healthy Students (SS/HS) Initiative has awarded over $2 billion in grants to more than 350 school districts in partnership with local mental health, law enforcement, and juvenile justice agencies. To estimate the impact of grantee characteristics, grant operations, and near-term outcomes in reducing violence and substance use, promoting mental health, and enhancing school safety, logged odds ratios (LORs) were calculated contrasting Year 3 with Baseline performance from grantee-provided data on seven outcome measures. After comparing grantee performance across outcomes and outcomes across grantees, the LORs were entered as dependent variables in a series of meta-regressions in which grantee characteristics, grant operations, and near-term outcomes were tested after controlling for pre-grant characteristics. Findings indicate that the SS/HS Initiative significantly improved most outcomes, that within-grantee performance varied greatly by outcome, and that random-effects meta-regression appreciably decreased the variance available for modeling. The approach demonstrates that the SS/HS Initiative is effective and that locally collected performance data can be used to estimate grantee success in improving youth outcomes.     

Looking at engagement and outcome from the perspectives of child protection workers and parents

This paper reports a study that sought to understand what facilitates engagement between parents and child protection workers and to ascertain the relationship between such engagement and intervention outcome. Quantitative and qualitative data were gathered through personal interviews with 131 worker-parent dyads (workers and corresponding parents receiving service) from 11 child protection agencies in Ontario, Canada. Measures included scales for engagement, parental well-being (depression and stress), and worker well-being (burnout, job satisfaction, stress). Outcome measures included perception of child safety, changed parenting practices and satisfaction. A relationship was found between workers' perception of parent engagement and parents' perception of their own engagement, as well as between the perceptions that workers and parents had around their own respective engagement. Workers who were satisfied with service outcomes were significantly more engaged than those who were unsatisfied. Parents thinking that their children were safer as a result of intervention were significantly more engaged than parents who thought that their children were less safe. The strongest reason given by parents for positive change was being able to trust their worker (p < .001) and believing that their worker was knowledgeable about parenting (p < .01). Qualitative data suggested that parents valued experienced workers because they thought such workers could better understand their problems and how to deal with them. Correspondingly, workers felt that experience enabled them to better understand clients' problems and provide more effective support. No relationship was found between parent engagement and parental depression or stress, but the mean depression score for parents placed them at risk of clinical depression. There was a negative correlation between worker stress and engagement. The study demonstrates that engagement between clients and workers is related to positive outcomes (as reported by workers and parents) and supports the contention that promoting engagement is integral to a successful child protection intervention.
