Immigrant quality and assimilation: a review of the U.S. literature

Empirical research on US immigrants is reviewed: their productivity and assimilation; their contribution and use of public services; and their impact on native Americans. I discuss the characteristics of cohorts of immigrants that enter the United States at different times, and then quantify the assimilation of immigrants, typically in terms of economic productivity of immigrants compared with natives. Few have found quantifiable negative effects of immigrants on native wages or unemployment in local labor markets, but a more general equilibrium approach than has been empirically implemented may be needed to draw any conclusions regarding the distributional consequences of immigration.

A double epidemic: crystal methamphetamine drug use in relation to HIV transmission among gay men

Emerging research on methamphetamine use among gay men suggests that growth in the use of this drug could present serious problems for HIV/AIDS prevention within the gay community. This article summarizes current studies on the extent, role, and context of methamphetamine use among gay men and its relationship to high risk sexual behaviors related to HIV transmission. Methamphetamine is often used by gay men to initiate, enhance, and prolong sexual encounters. Use of the drug is, therefore, associated with particular environments where sexual contact among gay men is promoted, such as sex clubs and large "circuit" parties. Research with gay and bisexual men indicates that methamphetamine use is strongly associated with risky sexual behaviors that may transmit HIV. This relationship, coupled with emerging evidence that methamphetamine use is on the rise among gay men, suggests that the drug could exacerbate the HIV/AIDS epidemic among this community. The article offers recommendations for further research and suggestions for prevention programs regarding methamphetamine use by gay men.     

Smallpox in nineteenth-century India

This study uses the large, but neglected, body of Indian historical demographic and health data to show that smallpox was a major killer in past times. At the start of the nineteenth century roughly 80 percent of India's population had no effective protection against the disease, and in these circumstances virtually everyone suffered from it in childhood. The main exception was Bengal, where the indigenous practice of inoculation greatly limited the prevalence of the disease. Smallpox case fatality in India was high—around 25–30 percent in unprotected populations—and significantly higher than estimated for unprotected populations in eighteenth-century Europe. Although vaccination reached India in 1802, the practice spread slowly during the first half of the nineteenth century. From the 1870s onward there were considerable improvements in vaccination coverage. The study demonstrates a close link between the spread of vaccination and the decline of smallpox. Whereas at the start of the nineteenth century the disease may have accounted for more than 10 percent of all deaths in India, by the end of the century smallpox had become a comparatively minor cause of death as a result of improved vaccination coverage.     

Fiscal impacts of immigration to the United States

"The purpose of this paper is to fill a gap in the demographic literature by reviewing previous fiscal studies of immigration in the United States. Each study is introduced by describing the data it uses, the methodologies employed in calculating costs and revenues, and the resulting estimates of fiscal consequences. Evaluative comments are also stressed. Seventeen studies are included in this review, divided into those that emphasize national fiscal impacts (these studies aggregate the effects of immigrants across all levels of government), state fiscal impacts, and fiscal effects on local governments."     

Ephebophilia and the creation of a spiritual myth in the works of Ralph Nicholas Chubb

The writings of Chubb, a boy-lover inclined to spiritualism will be studied with a view to understanding how he created an exonerative myth to reconcile his sexual interest with his desire for spiritual fulfillment. In this myth Chubb is the prophet of a deity who looks like a young boy and loving boys has spiritual significance. Chubb's pre-modern perception of his sexual orientation helps us to understand the changing views of homosexuality. This study may help in understanding the relationship between sexual desire and the development of personal myths.     

Dynamics ofSitotroga cerealella (olivier) (lepidoptera: gelechiidae) andSitophilus zeamais motschulsky (Coleoptera: Curculionidae) populations in a small bulk of stored corn

Summary The dynamics of Angoumois grain moth,Sitotroga cerealella (Olivier), and maize weevil,Sitophilus zeamais Motschulsky, populations breeding in a small bulk (initially 5.36 t) of shelled corn were studied over an 8-year period by monthly sampling. The weevil population showed wide fluctuations in density superimposed on a general decline with time. The moth population showed no upward or downward trend for the first 60 months, although it fluctuated widely. Following a decline that occurred between 56 and 60 months, the moth population fluctuated within a much narrower range, and there was a general decrease in density with time. The decline of the weevil population paralleled deterioration of the corn as did that of the moth population after ca 60 months, and the decline of both species probably resulted from increasing scarcity of suitable breeding sites. Both populations exhibited seasonal variation in density with minima in late summer and early fall, following periods of adversely high temperatures in the storage shed. The populations increased during the fall, leveled off or declined slightly during the winter months, and then increased to maximum levels in late spring or early summer. It thus appears that high temperatures had a greater adverse effect on the populations than low temperatures. The grain moth and the maize weevil both tended to be randomly dispersed at low population levels and moderately aggregated at intermediate and high levels, although the degree of aggregation was not correlated with population density when low population levels were considered separately, and the maize weevil showed a greater tendency for aggregation than did the grain moth. Analysis of individual samples at fixed points in time showed a conspicuous bias for negative correlation between numbers of the two species within sampling quadrats, suggesting a tendency for the two species to segregate within the grain mass. This process could have resulted from behavioral differences or from the destruction of one species by the other. Competitive displacement of the grain moth by the maize weevil has been demonstrated in laboratory experiments but has rarely been observed under natural conditions, and in our study the two species coexisted for 8 years in a relatively small grain bulk.     

Impact of developmental variance on behavior of models for insect populations II. Models for populations with density dependent restrictions on growth

Summary The impact of variation in developmental times on behavior of models for insect populations is investigated with special reference to models which include various types of intraspecific competition. At low densities, increases in developmental variation led to decreases in reproductive rate. At high densities, increases in developmental variation led to increases in reproductive rate. There was little change in the relationship between developmental variance and generation time as density increased.     

Heterosexual bias in psychological research on lesbianism and male homosexuality (1979-1983), utilizing the bibliographic and taxonomic system of Morin (1977)

Utilizing the concept of heterosexual bias, recent research on homosexuality is evaluated to see if this bias has lessened in recent years. In 1977 the suggestion was made that a new vision of homosexuality as an alternate and equally valid lifestyle would result in changes in the questions posed, the data collected, and the interpretations made in research on homosexuality. Recent journal article abstracts are examined and weighed to find the extend to which they reflect a change in the social values of the behavior under study. These findings are compared to those of the original study in 1977 and assessed to see if the predicted changes have come about. Strong evidence of such a change was found.     

The influence of catholic schools on the desegregation of public school systems: A case study of white flight in Boston

White flight from public school desegregation can result in educational and residential resegregation which defeat the purpose of desegregation programs. One form of white flight is pupil transfer to private schools, which in major metropolitan areas are predominantly Catholic schools. Unlike residential relocation, transfers to Catholic schools do not effect an increase in residential segregation and they constitute a potentially less permanent loss to the public system than that caused by relocation. Nevertheless, empty seats in area Catholic schools pose a threat to the success of any desegregation program. For the Catholic diocese, the white flight issue creates a complex conflict of interests, involving institutional self-interest and competing claims to moral principles and Church teachings.A case study of Boston indicates that approximately 2,000 students transferred to Catholic schools from the public system, accounting for over 20 percent of white pupil loss to the public system. This occurred despite diocesan policies designed to prevent white flight to Catholic schools. An analysis of political and institutional constraints on policy development and implementation provides a basis for predicting Church response to future desegregation programs in other locations. Suggestions for diocesan programs designed to address desegregation issues are included.This research was conducted as part of a national study of public school desegregation directed by Karl E. Taeuber. Funding was provided by the Institute for Research on Poverty and the Wisconsin Center for Educational Research, both at the University of Wisconsin at Madison. I wish to thank Dr. Taeuber for facilitating this particular study and for helpful comments on an earlier draft. I also wish to acknowledge the valuable assistance of Mary J. McDonald and Roger Hedge of the Massachusetts Department of Education and Rev. Eugene Sullivan, Superintendent of Schools of the Archdiocese of Boston.
