Productivity of highly skilled immigrants: economists in the postwar period

Prior work finds declining immigrant quality in the postwar period that is linked to source-country and skill-composition changes associated with the 1965 Immigration Act. This paper uses a unique panel of foreign- and native-born American Economic Association members to show that the highly skilled experienced a similar shift away from European migrants toward those from Asia. However, the findings do not indicate that this change in source-country composition has been accompanied by a decline in quality; rather, the most recent cohorts of foreign-born economists appear to be more productive than their native counterparts.     

Quantifying Potential Human Health Impacts of Animal Antibiotic Use: Enrofloxacin and Macrolides in Chickens

Use of similar or identical antibiotics in both human and veterinary medicine has come under increasing scrutiny by regulators concerned that bacteria resistant to animal antibiotics will infect people and resist treatment with similar human antibiotics, leading to excess illnesses and deaths. Scientists, regulators, and interest groups in the United States and Europe have urged bans on nontherapeutic and some therapeutic uses of animal antibiotics to protect human health. Many regulators and public health experts have also expressed dissatisfaction with the perceived limitations of quantitative risk assessment and have proposed alternative qualitative and judgmental approaches ranging from "attributable fraction" estimates to risk management recommendations based on the precautionary principle or on expert judgments about the importance of classes of compounds in human medicine. This article presents a more traditional quantitative risk assessment of the likely human health impacts of continuing versus withdrawing use of fluoroquinolones and macrolides in production of broiler chickens in the United States. An analytic framework is developed and applied to available data. It indicates that withdrawing animal antibiotics can cause far more human illness-days than it would prevent: the estimated human BENEFIT:RISK health ratio for human health impacts of continued animal antibiotic use exceeds 1,000:1 in many cases. This conclusion is driven by a hypothesized causal sequence in which withdrawing animal antibiotic use increases illnesses rates in animals, microbial loads in servings from the affected animals, and hence human health risks. This potentially important aspect of human health risk assessment for animal antibiotics has not previously been quantified.     

Breaking New Ground: Diverse Routes to College in Rural America*

Abstract Rural communities pose a challenge to status attainment models that explain children's educational attainment primarily in terms of the parents' education and professional status. Alongside the rural professional class are farmers of similar social status but with less education and other families that lack the status and resources of both professional‐class and farm families. The prolonged agricultural crisis in the American Midwest has turned rural youths toward college and has raised questions about the educational value of resources provided by farm parents and other rural parents. We classified youths from the Iowa Youth and Families Project into three SES groups: professional‐managerial, farm, and lower‐status. We compared these groups on resource levels and on the extent to which the resources predicted enrollment in a four‐year college one year after high school. Findings indicated three distinct routes to four‐year college. Professional‐managerial youths tended to follow the traditional path from parents' educational and other resources and support to their own academic involvement and aspirations for higher education. Successful farm youths, in lieu of parental educational advantages, drew on parents' community ties. Resourceful lower‐status youths, in the absence of family background advantages, generated educational attainment through early educational ambition and varied community and school involvements. Even relatively low levels of involvement were valuable to these youths' educational attainment.     

DOMINANT GROUP ETHNIC IDENTITY IN THE UNITED STATES:

This article explores several issues pertaining to the nature of dominant group ethnicity in the United States. Dominant group ethnic identity tends to be less visible and less salient as a result of dominant status. This "hidden' ethnicity has resulted in the systematic un-derdevelopment of the study of race and ethnic relations with regard to the analysis of the role of dominant group ethnicity. In addition, the taken-for-granted nature of dominant group identity has facilitated attempts by the dominant group to maintain its dominant position in the system of ethnic stratification. Finally, this article examines the process through which dominant group ethnicity has evolved and assesses the consequences of these changes for race and ethnic relations in the United States.     

The multiethnic placement act: Implications for social work practice

The issue of transracial adoption has been a controversial issue in foster care and adoption placement decisions. In 1994, the 104th Congress passed the Multiethnic Placement Act (MEPA), forbidding agencies receiving federal funds from solely considering race, culture, and ethnicity in making foster care and adoption placement decisions. Congress mandated that the Department of Health and Human Services (DHHS) develop policy guidelines for child placement agencies to follow. In April 1995, DHHS issued the guidelines that agencies were to follow. The authors of the paper discuss the MEPA, DHHS's policy guidelines for agencies and the guidelines' legal support, and the implications for social work practice in foster care and adoption placements.
