The consolidation of similar claims for compensation into a single large class of plaintiffs is referred to as “class action
litigation.” This practice can have both social costs and social benefits. For an example of the social benefits of consolidating
separate claims, if the facts giving rise to the claims are substantially similar, then there may be significant savings in
litigation and court administrative costs from presenting those facts once rather a multitude of times. There may, however,
be significant social costs to creating a class of litigants and consolidating their claims. For example, this practice may
empower those with frivolous negative expected-value claims to wring an unwarranted settlement from the defendant or defendants.
The article surveys other sources of social cost and benefit from class-action litigation, reviews the empirical literature
on these actions, and examines recent U.S. policy debates about reforming class-action litigation. The article concludes that
class-action litigation can have substantial net social benefits but only if courts assiduously oversee the class certification
process so as to identify and forestall the social-cost-generating aspects of class-action litigation. 相似文献

This article explores the dynamics of candidate ambivalence over the course of a presidential campaign. Candidate ambivalence tends to decrease as a campaign unfolds, although the rate of ambivalence decay is not constant across time or individuals. Two alternative theories of ambivalence change are considered and tested. Consistent with a motivational account, the results indicate that partisan reasoning contributes to the diminution of ambivalence over time. Consistent with an informational account, the results suggest that exposure to heterogeneous information heightens ambivalence. Ambivalence is least likely to decline among people who are exposed to cross‐cutting information, politically sophisticated individuals with weak partisan attachments, and, during the general election phase of the campaign, those who live in homogenous areas with little political competition. 相似文献

Accurate expectations about the outcome of elections play a central role in psychological and economic theories of voting. In the paper, three questions about voters’ expectations are investigated. First, we identify and test several factors that influence the overall accuracy or quality of voters’ expectations. Second, the phenomenon of “wishful thinking” is tested and confirmed for expectations about the electoral performance of individual parties and coalitions. Finally, two mechanisms how expectations might influence voting behavior are identified and tested. Based on surveys from Austria and Germany, the results suggest that voters not only rely on expectations to avoid casting “wasted” votes for parties without electoral chances, but that they are able to engage in fairly sophisticated strategic coalition voting. 相似文献

Adolescents who grow-up in rural areas often experience a tension between their attachment to the rural lifestyle afforded
by their home community and a competing desire to gain educational, social, and occupational experiences that are only available
in metropolitan areas. While these diverging pressures are well-documented, there is little information about linkages between
rural high school students’ views of their communities, their postsecondary aspirations, and their school adjustment. To address
this issue, this study examined perceptions of community and residential aspirations in an ethnically diverse sample of 8,754
rural adolescents (51.5% female) in relationship to their competence and risk status in high school. Participants were from
73 rural high schools across 34 states. In addition, ratings on participants’ school adjustment were provided by teachers
(n = 667). High competence students (i.e., those in configurations of high positive and low negative teacher-rated characteristics)
expressed positive perceptions of their rural lifestyle and many, particularly girls, indicated an interest in staying in
or returning to their home community. Low competence youth (i.e., those in configurations of low positive and high negative
teacher-rated characteristics) appeared to be less connected to their community and were more likely to express their intent
to leave and not return. These results appear to qualify current concerns about “rural brain drain” and also suggest that
the lack of attachment to the community may be a compounding risk factor for rural adolescents who have significant school
adjustment problems. 相似文献

The nation's largest charter management organization is the Knowledge is Power Program (KIPP). KIPP schools are emblematic of the No Excuses approach to public education, a highly standardized and widely replicated charter model that features a long school day, an extended school year, selective teacher hiring, strict behavior norms, and emphasizes traditional reading and math skills. No Excuses charter schools are sometimes said to target relatively motivated high achievers at the expense of students who are more difficult to teach, including limited English proficiency (LEP) and special education (SPED) students, as well as students with low baseline achievement levels. We use applicant lotteries to evaluate the impact of KIPP Academy Lynn, a KIPP school in Lynn, Massachusetts that typifies the KIPP approach. Our analysis focuses on special needs students that may be underserved. The results show average achievement gains of 0.36 standard deviations in math and 0.12 standard deviations in reading for each year spent at KIPP Lynn, with the largest gains coming from the LEP, SPED, and low‐achievement groups. Average reading gains are driven almost entirely by SPED and LEP students, whose reading scores rise by roughly 0.35 standard deviations for each year spent at KIPP Lynn. 相似文献

The difficulty of coordinating service provision in interagency programs is a challenge for many working in public policy. We reflect on lessons learned through evaluating two inter‐agency supported housing programs for people with mental illness and propose a framework outlining components needed for well co‐ordinated service provision. We specify collaborative mechanisms at the policy, agency, service and client level. The key component is the role of an ‘integration coordinator': a person who is able to facilitate relationships and ensure effective information flows. Relationships need to be actively maintained to meet the inevitable challenges that will arise in complex interagency systems. The framework is relevant to policymakers across the public sector, including mental health, drug and alcohol, aged care, and policing. 相似文献

LUCIO-Direct-enzyme linked immunosorbent assay (ELISA) tests were validated for the screening of drugs of abuse cannabis, opiates, amphetamines and cocaine in urine for the new German medical and psychological assessment (MPA) guidelines with subsequent gas chromatographic-mass spectrometric (GC-MS) confirmation. The screening cut-offs corresponding to 10 ng/mL 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH), 50 ng/mL amphetamine, 25 ng/mL morphine and codeine and 30 ng/mL benzoylecgonine were chosen at the point where the number of false negatives was lower than 1%. Due to their accuracy, ease of use and rapid analysis, these ELISA tests are very promising for cases where a large proportion of the tests are expected to be negative such as for abstinence monitoring as part of the driving licence re-granting process. 相似文献
