The Tanda: A Practice at the Intersection of Mathematics,Culture, and Financial Goals

We present an analysis and discussion of the tanda, a multiperson pooled credit and savings scheme (a rotating credit association or RCA), as described by two informants from Mexican immigrant communities in California. In the tanda, participants contribute regularly to a common fund which is distributed to participants on a rotating basis. We analyze the tanda at multiple levels (as a mathematical, cultural, and distributed practice) and identify points of intersection and conflict. Contrary to many formal or school-based conceptions of mathematics, mathematical work in the context of the tanda is in service of, and intimately tied up with, cultural goals and values. Likewise, cultural means and mathematics are employed to personal ends. We argue that the tanda should be of enduring interest, particularly among educators interested in bringing more authentic, culturally-relevant mathematics into classroom settings, because it so clearly illustrates how mathematical and cultural processes can interact in the context of personal goals, and provides a potentially valuable template for engaging, consequential, and successful mathematics.

Mortality Differentials by Marital Status: An International Comparison

Although the greater longevity of married people as compared with unmarried persons has been demonstrated repeatedly, there have been very few studies of a comparative nature. We use log-linear rate models to analyze marital-status-specific death rates for a large number of developed countries. The results indicate that divorced persons, especially divorced men, have the highest death rates among the unmarried groups of the respective genders; the excess mortality of unmarried persons relative to the married has been generally increasing over the past two to three decades; and divorced and widowed persons in their twenties and thirties have particularly high risks of dying, relative to married persons of the same age. In addition, the analysis suggests that a selection process is operating with regard to single and divorced persons: the smaller the proportion of persons who never marry or who are divorced, the higher the resulting death rates.     

The business of education: a new paradigm

Business as usual is not the answer these days. But how do you create a new paradigm for academic educational and research endeavors? There is increasing pressure to separate the costs of providing care to patients from those of educating students and residents. It is evident already that we will not enjoy the flexibility of the past to cross-subsidize the academic effort. Presented here is a case study--a joint venture between Harvard Medical School and Beth Israel HealthCare created to sustain the academic mission, as distinct from its clinical business, and promote innovation in medical education and research through intellectual leadership, dedicated state-of-the-art facilities, and a focused development effort.     

Can fertility be estimated from current pregnancy data?

Summary This paper explores the feasibility of estimating fertility from reports on current pregnancies collected in single-round sample surveys. Data from 15 countries in the World Fertility Survey are used to evaluate the possibilities. The results indicate that neither the age pattern of fertility nor the total fertility ratio can be reliably estimated from current pregnancy data. For almost all countries, the total fertility ratio based on recent births is higher than that based on current pregnancies, even when the latter estimate is restricted to higher durations of pregnancy.     

Far eastern patterns of Mortality

Summary In this paper a mortality pattern is identified which has not previously been described by model mortality schedules and seems to have occurred only in populations in the Far East. Mortality schedules in Taiwan, Hong Kong, Singapore, and Korea during the past several decades have been characterized by excessively high death rates of men at the older ages. This excess mortality has progressively diminished and most recent death rates for men show only slight deviations from West model life tables. An examination of statistics on causes of death suggests that tuberculosis is at least partly responsible for the excess mortality of men.     

Exceptionalism and Internationalism: The Origins of American Social Science Reconsidered

This paper examines the international context in which American social science was institutionalized in the generation after the Civil War, following the foundation of the American Social Science Association in 1865. The ASSA was modelled on an influential British forum, founded eight years previously, the National Association for the Promotion of Social Science. A comparison of these two organisations from the 1860s to the 1880s allows consideration of British intellectual and political influences on the first American social scientists. It also helps in the identification of the social and political attitudes of the well-born, cosmopolitan, and high-minded American reformers attracted to social science at this time. The theme of American exceptionalism has recently been emphasized when considering the motives and intentions of early social science in the United States. It is argued here that the replication in America of models of the new discipline which were first developed in Britain, is indicative also of a self-conscious internationalism among the American social-scientific community of this period. In addition to an institutional comparison, the article examines the careers and ideas of several representative figures in this process of Anglo-American liberal transference, among them the physician Dr. Edward Jarvis, the feminist Caroline Healey Dall, the jurist David Dudley Field, and the famed British interpreter of American experience, James Bryce.     

New insights into the Far Eastern pattern of mortality

Some of the highest levels of excess mortality of males found anywhere in the world were present in several Far Eastern populations during the 1960s and 1970s but have progressively disappeared since that time. This study uses cause-of-death data to determine the diseases responsible for the existence and attenuation of these sex differences in Hong Kong, Singapore, and Taiwan. The results indicate that respiratory tuberculosis is the single most important underlying cause of the existence and attenuation of the pattern, that the role of liver diseases is not clear cut, and that other causes (such as cardiovascular diseases) are also important. A review of numerous risk factors yields no compelling reason why these populations experienced such large sex differences in mortality. However, it seems likely that public health and biomedical improvements (particularly those related to the reduction in mortality from tuberculosis) played a critical role in the attenuation of the Far Eastern mortality pattern.
