A DISCRETE DYNAMIC OPTIMIZATION MODEL FOR MADE-TO-ORDER COST ANALYSIS

A model is presented that yields optimal production rates for a firm producing a contracted order. The model is unique in that it considers the influence of production rate and learning on total program cost. An application to the specific characteristics of two military production programs is presented. As demonstrated by the application, models of this type may be used as decision-making tools when negotiating the cost impact of contract modifications.     

Anthropological Theories of Low-Wage Work

This review assesses the use of anthropological theories in the examination of low-wage work. Due to the vast differences existing between different cultures in low-wage work, this review focuses on theories that have been applied in Western, and mainly American, contexts. There are primarily three fields from which this literature is drawn: economic anthropology, gender and race anthropology, and theories of power—the last integrates all these theories. Differences and controversies over the applicability of these theories are also highlighted. The review concludes with a conceptual map describing the interrelatedness of these theories and how they explain the realities of low-wage workers.     

The Balance Point: Keeping Serial Bibliographic Records Viable in a Digital Age

Abstract

Michael Norman, head of serials cataloging at University of Illinois at Urbana-Champaign (UIUC) library, describes his library's development of an integrated management system for serials, the Online Research Resources (ORR). The ORR was designed to draw together and deliver to the public a wide range of information related to the library's serial holdings that previously could only be obtained by consulting a number of sources. With a single search, UIUC patrons can now consult the ORR for serials information such as variant titles, online availability, subject categories, print summary statements, ISI impact factor, where the title is indexed, and whether it is peer reviewed—an innovation sorely needed and highly welcomed by librarians and patrons alike.     

The Incompatibility of Materialism and the Desire for Children: Psychological Insights into the Fertility Discrepancy Among Modern Countries

We examined factors related to attitudes toward marriage and the importance of having children in both the US and Singapore. Path analysis indicated that life dissatisfaction leads to materialism, and both of these factors lead to favorable attitudes toward marriage, which leads to greater desire for children. Further analysis indicated this model was effective in explaining the difference in desire for children between Singaporeans and Americans, whereby Singaporeans have lower life satisfaction, higher materialism, and lower attitudes toward marriage and children. Materialistic standards of success were also related to the emphasis women placed on potential marriage partners’ earning capacity. As Singaporean women had higher materialistic standards, they also placed higher emphasis on potential mates’ earning capacity. Results suggest a consideration of psychological variables such as life satisfaction, materialism, and mate preferences may lead to a better understanding of larger-scale socioeconomic issues, including low fertility rates among developed East Asian countries.     

Selection of cost-optimal 2k−p fractional factorials

Selecting an optimal 2^k?pfractional factorial is structured as a mathematical programming problem. An algorithm is defined for the solution, and the case of additive costs is shown to have a known solution for resolution III designs.     

Social orders

This review discusses the stability of social orders in light of the recent work Violence and Social Orders by Douglass North, John Wallis and Barry Weingast (hereafter NWW). The purpose of this book was to understand the two great transitions that have occurred in human society. The first, the agricultural revolution, resulted in a transition from hunter–gather society to what NWW call limited access society. This first transition occurred at various times and places, but generally about 10,000 years before the present. The second revolution, the social/industrial/technological revolution, from limited access to what NWW call open access, occurred initially in a few societies, particularly Britain and the United States, within a fairly brief period between 1600 and 1860. Currently, all the West European economies, as well the Western offshoots (the United States, Canada, Australia and New Zealand) and Japan have crossed the economic threshold of $20,000/capita. However, inequality across the set of all political economies is extreme, and likely to increase. The paper attempts to complement the institutional analysis of NWW, deploying some theoretical ideas from social choice theory, game theory, and economics (particularly the role of factors of production, land, capital and labor). Emphasis is placed on the variation of risk preference between autocrats and other factor groups. The discussion also alludes to the notion of structural stability of dynamical social systems, and the possibility of chaos. It is argued that all the limited access societies face a Malthusian constraint, generated by the pressure of population on land. In such societies, particularly in Africa in the present day, this quandary over land is likely to lead to the exercise of power by risk preferring autocrats who will restrain any move to open access democracy.     

Marital Aspirations,Sexual Behaviors,and HIV/AIDS in Rural Malawi

We explore how marital aspirations are related to the sexual behaviors of adolescents and young adults in Malawi, where HIV/AIDS prevalence among adults exceeds 10%. We also consider whether the specter of AIDS is shaping ideals about marriage. By combining survey data (N = 1,087) and in‐depth interviews (N = 133) with young Malawians from the Malawi Diffusion and Ideational Change Project, we show that looking for and finding a suitable spouse are linked to sexual behaviors and, thus, HIV risks. Moreover, concerns about contracting HIV are closely tied to the ideal characteristics of a future spouse. Our findings draw long‐overdue attention to the importance of marital aspirations in understanding adolescent sexual behaviors and risks in the era of AIDS.
