This study uses U.S. census data from the year 2000 to analyze the earnings of Mexican immigrants along the U.S.‐Mexico border while accounting for the location in which they work. The empirical results indicate that Mexican entrepreneurs who live in U.S.‐border cities but primarily operate in Mexico accrue a significant earnings premium over their entrepreneurial and salaried counterparts working on the U.S. side of the border, even after controlling for differences in observable characteristics. This work‐location earnings gap widens when focusing on Mexican business owners lacking U.S. citizenship. It follows that policies which reduce trade and labor flows across the U.S.‐Mexico border may inadvertently dampen the entrepreneurial activities of foreign‐born residents in U.S.‐border cities.  相似文献

This article examines the influence of quality‐adjusted educational attainment on growth and tests whether it facilitates the transfer of technology developed at the frontier for a panel of 60 countries. Using outcomes of pathogen stress as instruments, the results show that quality‐adjusted educational attainment and its interaction with distance to the frontier play important roles for growth.

Mexican cinema, one of the most active in Latin America, dates from 1896, while sound film recently celebrated its fiftieth anniversary there. Among the many prominent Mexican cineasts whose films form a repertoire of solid artistic achievement is Alejandro Galindo. Like many fellow-filmmakers, directors and actors, Galindo did his aoprenticeship in Hollywood, returning to Mexico in 1930 to become one of Mexico's most creative and dynamic practitioners of cinematic art. Carl Mora highlights his accomplishments while placing him in the perspective of the development of the Mexican film industry. For example, during World War II the industry boomed because of the demand in Latin America for authentic Latin American cinema. With this impetus, Mexico (and Alejandro Galindo) enjoyed a decade of growth and popularity. Unlike most other Mexican cineasts, Galindo dealt with the dislocations that a rapidly changing economy and increased urbanization brought to both the workers and the middle class. Mora discusses several of his most important films, amply demonstrating the impact Galindo believed that cinema could have on society. He left a legacy that is admired today by critics and filmmakers.  相似文献

Building upon the ideas first exposed by Theil and Finizza (1971) and Fuchs (1975), this paper presents an additively decomposable segregation index based on the entropy concept used in information theory. For any pair of classification variables in a given year, the index is decomposed into a between-group and a within-group term. To analyze intertemporal changes in gender segregation for a given partition, the index is decomposed into two terms that capture, respectively, gender composition effects, and changes in the groups' demographic importance. These decompositions are illustrated with Spanish data on occupations and human capital levels for 1977 and 1992. It is found that, in both years, the higher the educational level, the smaller is gender segregation for most age groups. Moreover, gender segregation decreases with age in all educational categories. However, most gender segregation takes place within, rather than between, age/education categories. Lastly, changes in gender composition across occupations, nearly offset by occupational mix changes, account for a decline of 2% in total gender segregation over this period.  相似文献

This paper uses a novel approach to infer hospital technical quality from revealed preferences over residency programs. Specifically, we use Spanish medical graduates’ residency choices made from 1995 to 2000. We start by estimating a model of medical graduates preferences that controls for hospital, proximity, specialty, and gender effects. We interpret the coefficients on the hospital dummy variables as measures of medical graduates’ preferences over hospitals. Our results show that graduates do indeed discriminate between hospitals and that their preferences correlate with hospital‐specific covariates arguably related to hospital training quality. We then show that preferences from medical graduates are positively and statistically significantly correlated with risk‐adjusted hospital rankings based on five alternative outcome measures. Finally, we construct reputation scores for each hospital using news story counts in three media outlets and find that medical graduates’ preferences are especially valuable for inference of hospital technical quality of care as they do not simply reflect well known reputation.  相似文献

Abstract

Drinking games are associated with excess alcohol use and alcohol-related problems, yet it is unclear whether they are unique to the college environment or whether students come to college familiar with such games. The authors queried 1,252 students attending voluntary summer orientation programs about their experiences with drinking games. A majority (63%) indicated they had played drinking games and viewed them as a means to get drunk quickly and to socialize, control others, or get someone else drunk. Logistic regression analyses revealed that familiarity with drinking situations was associated with a greater likelihood of playing drinking games. Students who reported drinking more frequently and consuming greater quantities of alcohol than others, having lifetime marijuana use, and initiating alcohol consumption between the ages of 14 and 16 years were significantly more likely to have participated in drinking games. These findings demonstrate the importance of considering students' participation in drinking games when campus officials address alcohol use.  相似文献

Abstract

“Epidemiology of Diarrhea in Travelers,” ROBERT STEFFEN, FRANZ VAN DER LINDE, KLAUS GYR, MEINRAD SCHAR. To investigate diarrhea in tourists on a worldwide scale, 16,568 passengers were interviewed during their flights home from 13 destinations in various climatic regions. Significant differences in diarrheal incidence were observed between individual destinations and also between hotels in the same area. The highest rates exceeded 50%. Younger persons were more often affected. Sex, travel characteristics, and a record of former tropical journeys influenced the incidence to a minor degree. Even in the tropics, diarrhea usually takes a short (average, 3.6 days) and mild (average of 4.6 stools per day) course. Prophylactic or therapeutic medication only slightly influenced these values. The various regions showed minor differences in chronology and symptomatology. This is consistent with quantitative rather than qualitative geographic variations in causative agents. The traditional nutritional recommendations for prophylaxis seemed to be unrealistc and usually unsuccessful. (Journal of the American Medical Association 1983;249:1176–1180.)  相似文献

Abstract

The author argues that referral of alcohol-abusing college students to off-campus treatment services, although necessary for some, is not optimal for many. He advocates the implementation of comprehensive on-campus services for students committed to recovery in order to optimize their treatment while allowing them to remain in school and work towards their degree. The author suggests that such on-campus recovery services provide additional benefits to the college or university as well as to other students, and he proposes that on-campus alcohol-abusing students in recovery can serve as important opinion leaders and role models for their peers.  相似文献

Abstract

Healthcare in a major university setting poses unusual challenges and great opportunities. Two traditionally challenging areas in patient distribution are the initial intake of allergy/immunization patients and the triage of outpatients in the general medical clinic. The authors describe the use of the FOCUS-PDCA quality improvement (QI) problem-solving process for each situation. After identifying major problems, the health center established cross-functional teams of experts representing the allergy/immunization and general medical clinics. The teams analyzed the problems with a flow chart and undertook studies to further elucidate causes and potential solutions. They listed potential solutions in order of priority and submitted them to the student health center director for review and initiation. Each team then used the PDCA (plan-do-check-act) cycle to put approved solutions into effect. Permanent improvements made in each area resulted in a more effective and efficient patient distribution system, favorable staff comment, and greater patient satisfaction.  相似文献

Abstract

College students often delay or avoid seeking testing for sexually transmitted infections (STIs), even if the services are readily available. We used in-depth, semistructured interviews to survey 41 college students aged 18 to 23 years about factors that influence decisions about STI testing. We grouped statements into 9 themes that represent influences on the decision. The most frequently mentioned factors were negative consequences of testing and perceived vulnerability to infection; other issues that influenced decision making included perceived benefits, perceived severity of diseases, public knowledge and opinion, social norms, provider characteristics, test-site characteristics, and personal considerations. Social stigmas and negative consequences appear to represent significant barriers to college students' being tested, which could increase the risk of spreading infections to others. Clinicians and health educators should raise students' awareness of the need for screening and should work to reduce the barriers to screening, including social stigmas and negative consequences.  相似文献
