Like oysters on the half shell, some things are better when they're raw. In evaluating the performance of organizations and providing guidance for improving performance, however, raw performance measures, such as test scores or success rates, are often inferior to performance measures adjusted for client and environmental characteristics, or adjusted performance measures (APMs). Using examples from a variety of public services and data on public schools in Georgia, we compare the performance data generated by raw scores and by APMs. We conclude with guidance for constructing and using adjusted performance measures. 相似文献

The regulatory compliance defense holds firms liable whose productsor product warnings fail to satisfy federal regulatory standards,but does not exculpate firms that comply. Rather, complianceis relevant evidence for a jury to consider in a products liabilityaction. This article argues that the defense should exculpatecompliant firms as a matter of law. A Congress that thoughtabout the matter would prefer this judicial construction ofan unclear safety statute. To defend this view, the articleargues that a legislature can have intentions in a normativelymeaningful sense, that claims that a Congress or its agenciesare captured by special interests should be nonjusticiable,and that, when a court is in doubt as to what a legislatureintended, it should adopt that construction of the relevantstatute that would be easiest for the legislature to correctif the court errs. In this case, it is easier for Congress tocorrect a construction that it intended to exculpate compliantfirms than a construction that it did not. 相似文献

This paper investigates the impact of extending free school lunch to all students, regardless of income, on academic performance in New York City middle schools. Using a difference-in-differences design and unique longitudinal, student-level data, we derive credibly causal estimates of the impacts of “Universal Free Meals” (UFM) on test scores in English Language Arts (ELA) and mathematics, and participation in school lunch. We find UFM increases academic performance by as much as 0.083 standard deviations in math and 0.059 in ELA for non-poor students, with smaller, statistically significant effects of 0.032 and 0.027 standard deviations in math and ELA for poor students. Further, UFM increases participation in school lunch by roughly 11.0 percentage points for non-poor students and 5.4 percentage points for poor students. We then investigate the academic effects of school lunch participation per se, using UFM as an instrumental variable. Results indicate that increases in school lunch participation improve academic performance for both poor and non-poor students; an additional lunch every two weeks increases test scores by roughly 0.08 standard deviations in math and 0.07 standard deviations in ELA. Finally, we explore potential unintended consequences for student weight outcomes, finding no evidence that UFM increases the probability that students are obese or overweight. We also find no evidence of increases in average body mass index (BMI). Instead, we find some evidence that participation in school lunch improves weight outcomes for non-poor students. Results are robust to an array of alternative specifications and assumptions about the sample. 相似文献

Existing theoretical perspectives suggest that adolescents who are characterized by high achievement may experience social sanctions from peers. The central premise is that, in many North American settings, adolescent peer groups are characterized by negative attitudes toward the school environment. To test these hypotheses, we examined associations between indicators of low social power (unpopularity and victimization by peers) and academic competence for 415 adolescents (193 boys; 222 girls) attending an urban high school. This school served neighborhoods that were characterized by a moderate degree of economic distress and the students were predominately of Hispanic American descent. A short-term longitudinal design was used, with two waves of data collected over consecutive school years. The adolescents completed a peer nomination inventory assessing relational and overt victimization by peers, unpopularity, and social rejection. In addition, we obtained math and language arts grades from school records, and we assessed behavioral engagement in school with a self-report inventory. Structural equation models did not reveal a strong pattern of longitudinal change in social standing with peers or academic functioning. However, we found positive correlations between academic achievement and problematic peer relationships in both years of the project. We also found evidence that gender moderates these associations, with the effects reaching significance only for boys. Our results provide evidence that, in some settings, high achieving adolescents can be prone to negative treatment or marginalization by peers. 相似文献

Adolescents from Mexican immigrant families are often embedded in a challenging social environment and experience multiple contextual stressors, including economic stress, discrimination, and foreigner stress. We consider how the effects of these contextual stressors may be amplified or diminished for adolescents who function as language brokers, interpreting and mediating for their English-limited parents. Using two waves of survey data collected from a sample (N?=?604 at Wave 1; N?=?483 at Wave 2) of Mexican American adolescents with ages ranging from 11 to 15 (Mage?=?12.41, 54% female), four distinct brokering—stress profiles were identified. Latent profile analyses revealed that with moderate levels of contextual stress, adolescents with more positive language brokering experiences (protective group) demonstrated more favorable outcomes than those with neutral language brokering experiences (moderate group) and those who did not involve themselves as frequently in language brokering activities (less-involved group). In contrast, high levels of contextual stress, coupled with more negative language brokering experiences (risk group), produced the least favorable outcomes among adolescents. 相似文献

Coping strategies and identity processes are hypothesized to influence one another over time. This three-wave longitudinal study (N?=?458; 84.9% women) examined, for the first time, how and to what extent identity processes (i.e., commitment making, identification with commitment, exploration in breadth, exploration in depth, and ruminative exploration) and coping strategies (i.e., problem solving, social support seeking, and avoidance) predicted one another over time. Cross-lagged analyses indicated that processes of identity exploration seemed especially to be intertwined with different coping strategies over time, suggesting that identity exploration may resemble problem-solving behavior on the pathway to an achieved identity. Commitment processes were found to be influenced by certain coping strategies, although identification with commitment also negatively influenced avoidance coping. These temporal sequences remained significant when controlling for baseline levels of Big Five personality traits. Hence, evidence was obtained for reciprocal pathways indicating that coping strategies and identity processes reinforce one another over time in college students. 相似文献

This article examines the previously unexplored current of Freethinking feminism in the second half of the nineteenth century. Active in the women's movement of this period, Freethinking feminists were nonetheless viewed as a liability—an attitude that contributed to their exclusion from much of the subsequent historiography. Such marginalisation was due not only to their vocal opposition to all forms of religion, but also their openness to discussing new ways of organising heterosexual relationships. This article focuses on Freethinking feminist critiques of marriage and support for free unions. It demonstrates that these issues continued to be debated in the Secularist movement at a time when many other radical organisations—including much of the women's movement—kept silent on such topics. In this way, Freethinking feminists kept alive the more radical and libertarian critiques of traditional sexual morality developed by Owenite feminists in the 1830s and 40s. The author argues that the ideology of Freethought propelled its adherents to readdress questions of sex within a new 'Secularist' ethical framework. Fierce debate ensued, yet commitment to freedom of discussion ensured that 'unrespectable', libertarian voices were never entirely silenced. Freethinking feminism might, then, be viewed as the 'missing link' between early nineteenth-century feminist visions of greater sexual freedom and the more radical discussions of sexuality and free love that began to emerge at the fin de sicle. 相似文献

- The Chicago Board Options Exchange's (CBOE) Volatility Index (VIX) is the premier established benchmark of near‐term market volatility. It is also referred to as the ‘investor fear gauge’ because it provides a consistent measure of market turmoil. We examine the VIX as it relates to Presidential popularity as indicated by the Gallup Organization's ongoing poll of US Presidential approval ratings. Our analysis indicates that the expected volatility of the market is highly related to Presidential approval. We then examine the strength and implications of this relationship in order to further establish the link between the economy and Presidential approval.
