We examine the existence and magnitude of own‐nationality bias. Using player‐match level data from 12 seasons of the UEFA Champions League (UCL) and referee assignment policies that pair players and referees from the same country, we determine the bias that referees exhibit toward players from their native country. Players officiated by a referee from the same country receive a 10% increase in beneficial foul calls. Referees' own‐nationality bias is more pronounced for national team players, players at home, and in later stages of the tournament. Elite referees exhibit as much, or more, own‐nationality bias as their less experienced counterparts. (JEL L83, J15)  相似文献

The large literature on health differentials between rural and urban areas relies almost exclusively on cross-sectional data. Bringing together the demographic literature on area-level health inequalities with the bio-physiological literature on children’s catch-up growth over time, this paper uses panel data to investigate the stability and origins of rural–urban health differentials. Using data from the Young Lives longitudinal study of child poverty, I present evidence of large level differences but similar trends in rural versus urban children’s height for age in four developing countries. Further, observable characteristics of children’s environment such as their household wealth, mother’s education, and epidemiological environment explain these differentials in most contexts. In Peru, where they do not, children’s birthweight and mothers’ health and other characteristics suggest that initial endowments—even before birth—may play an important role in explaining "residual" rural–urban child height inequalities. These latter results imply that prioritizing maternal nutrition and health is essential—particularly where rural–urban height inequalities are large. Interventions to reduce area-level health inequalities should begin even before birth.  相似文献

This study aimed to evaluate the comparative effectiveness of individual therapy and combined individual and group therapy in the treatment of the psychological sequelae of child sexual abuse. The Child Behaviour Checklist (CBCL), the Youth Self Report form (YSR), the Children's Depression Inventory (CDI) and the Trauma Symptom Checklist for Children (TSCC) were administered before treatment and 6 months later to a group of 20 young people who participated in individual therapy (IT) programmes and to a group of 18 young people who participated in programmes that involved combined individual and group therapy (IGT). For both types of programmes, statistically significant improvement occurred on the following scales: the total problems, internalizing problems, externalizing problems, withdrawn, somatic complaints, anxious/depressed, social problems, attention problems and aggressive behaviour problems CBCL scales; the total depression, interpersonal problems and anhedonia CDI scales; and the depression and anger TSCC scales. The only scale for which one therapy programme led to greater improvement than another was the CDI ineffectiveness scale. The IGT programme led to a reduction in the mean CDI ineffectiveness score, whereas a slight increase in the mean ineffectiveness score occurred in the IT group. There were no significant differences in the rates of clinically significant improvement associated with the two treatments and no major differences between cases who improved and those that did not improve over the course of therapy. From this study, it may be concluded that after 6 months, individual therapy and combined individual and group therapy were equally effective in the treatment of the psychological sequelae of child sexual abuse.

Abstract

The H1N1 influenza A virus (A/USSR/90/77) appeared first in China, then spread to the United States in January 1978, causing significant outbreaks of influenza among younger age groups. Because college students were particularly affected, epidemiologic investigations were done to define the impact of illness on university populations.

We describe influenza outbreaks involving two college campuses (the Universities of Michigan and Colorado). At both schools, illness attack rates were significantly higher for students than for older faculty and staff members. At the two respective campuses, 25 and 36% of those ill who were surveyed sought medical care. Bed confinement averaged 3.8 days at one school (Michigan). At the other school (Colorado), ill students missed an average of 2.8 days of class. Influenza A (H1N1) virus was isolated from specimens from acutely ill students at both campuses.

These investigations illustrate the practical usefulness of college campuses as sites for monitoring the activity of influenza and other acute respiratory diseases.  相似文献

Gambling is fast becoming a public health problem in the United States, especially among emerging adults (18–25 year olds). Since 1995, rates have recently doubled with around 7–11 % of the emerging adult population having problems with gambling (Shaffer et al. in Am J Public Health 89(9):1369–1376, 1999; Cyders and Smith in Pers Individ Diff 45(6):503–508, 2008). Some states have lowered their gambling age to 18 years old; in turn, the gambling industry has recently oriented their market to target this younger population. However, little is known about the gender variation and the factors placing emerging adults at risk for getting engaged and developing problems with gambling. The purpose of the study was to determine the risk factors accounting for gender differences at the two levels of gambling involvement: engagement and problems. Mediation analyses revealed that impulsive coping and risk-taking were significant partial mediators for gender differences on engagement in gambling. Men took more risks and had lower levels of impulsive coping than women, and those who took more risks and had lower levels of impulsive coping were more likely to engage in gambling. Risk-taking and social anxiety were the significant mediators for gender differences in problems with gambling. Men took more risks and were more socially anxious than women, and greater risk-taking and more socially anxious individuals tended to have more problems with gambling. Implications for counseling preventions and intervention strategies are discussed.  相似文献

Pathways to legal immigration   总被引:1,自引:0,他引:1  
In this paper we use the New Immigrant Survey Pilot Study (NISP) todescribe the amount and kind of experience that immigrants accumulate in the United States before they become permanent resident aliens. The NISP surveyed a representative sampleof legal immigrants who acquired residence papers during July and August of 1996, yielding a completed sample of 1,135 adults. Our analysis revealed that roughly two-thirds of thesenewly arrived immigrants had prior experience in the United States within one of six basic categories: illegal border-crossers, visa abusers, non-resident visitors, non-resident workers, students or exchange visitors, and refugees/asylees. Each of these pathways to legal immigration wasassociated with a different profile with respect to nationality, social background, and economic status. Using simple earnings regressions we demonstrate how these differences can yield misleading conclusions about the process of immigrant adaptation and assimilation, even if measured effects are reasonably accurate. We suggest that social scientists should changethe way they think and ask about immigrants' arrival in the United States.  相似文献

In studies of combinations of agents in phase I oncology trials, the dose–toxicity relationship may not be monotone for all combinations, in which case the toxicity probabilities follow a partial order. The continual reassessment method for partial orders (PO‐CRM) is a design for phase I trials of combinations that leans upon identifying possible complete orders associated with the partial order. This article addresses some practical design considerations not previously undertaken when describing the PO‐CRM. We describe an approach in choosing a proper subset of possible orderings, formulated according to the known toxicity relationships within a matrix of combination therapies. Other design issues, such as working model selection and stopping rules, are also discussed. We demonstrate the practical ability of PO‐CRM as a phase I design for combinations through its use in a recent trial designed at the University of Virginia Cancer Center.
