Application of extreme value theory to the bec family of distributions

Arnold and Strauss (1988) derived a family of bivariate life distributions having the property that the conditional distributions are exponential. Asymptotic distributions for the marginal and bivariate extremes for this family of distributions are derived employing the asymptotic theory of extreme order statistics.     

Adolescent girls’ race/ethnic status, identities, and drive for thinness

Using data from 7272 adolescent US girls, we explore how girls’ race/ethnic group status affects their bodyweight, perceptions of overweight, and weight control practices. We hypothesize that a girl’s race/ethnic status influences her basic identity which in turn prompts her to adopt or reject a “drive for thinness.” After controlling for family and peer support, school engagement, family SES, maturation, and family structure, we find that girls’ race/ethnic status influences their susceptibility to the thinness ideals of mainstream culture. African American girls weigh more than Asian, Hispanic, or White girls, but at any given weight they perceive themselves as overweight and attempt to control their weight less. Asian American and White girls invest most in thinness dynamics. Some evidence also suggests girls from lower SES families are less driven to be thin. Our results affirm the utility of viewing material bodies as “situations” that are experienced and interpreted in accord with identity group relations and dynamics.     

Participation, Authority, and Distributive Equity in East Timorese Development

The anthropology of development seeks to understand the complex encounter between international and national development regimes and local patterns of livelihood and being. As science and development move objects, at once material and discursive, through the networks of the social to reach “impoverished” others, local groups reach out to development actors to evaluate and appropriate their resources and accept or redirect those efforts. In a political interplay of disciplinary measures and localizing translations, development projects are re-invented, or aspects thereof refused, just as development actors strain to keep projects on track. With input from science and technology studies, this article explores the participatory, authoritative, and distributive dimensions to agricultural development in East Timor. Across four cases studies—a dairy, a greenhouse, a seed development program, and a permanent farming initiative—the politics of projects are compared and discussed within the broader context of colonial and postcolonial development. The article is based on a total of 1 year of fieldwork conducted in 2003, 2008, and 2009.     

Naturing the Nation: Aliens,Apocalypse, and the Postcolonial State

The purpose of this study is to understand how the British Canadian Frank Schofield transformed himself into an established missionary scholar and nobleman in Korea. The study employs its framework from the structure of cultural exchange itself in its survey of Schofield's career. It examines the relevant aspects of Korean and Western cultures, and the characteristics of Schofield who linked them. The case, including themes significant both to Korean and Western cultures, such as the importance of spirituality, an emphasis on education, and the ideals of justice and love, explains reasons for his success as a cultural mediator between Korea and the West. It reveals that the flow of information and ideas between Koreans and Schofield illustrates the ability of intercultural contact to influence the initiating as well as receiving culture. It suggests that such a distinction between sender and receiver may carry little ultimate significance. Finally, it argues that individuals of different cultures can convey information and ideas effectively only if the conveyer learns about the target individuals for the information and ideas, and communicates on the basis of that knowledge, as intercultural communications occur between the individuals of different cultures.     

A further examination of antecedents of correctional staff life satisfaction

Working in corrections is not only a demanding job, but a socially important one. While a growing number of studies have examined how the work environment impacts the job stress, job satisfaction, and organizational commitment of staff, very few studies have examined how working in corrections impacts the life satisfaction of workers. The current study utilized OLS regression to examine the antecedents of life satisfaction among staff at a Midwestern private prison. Job satisfaction had a positive relationship with life satisfaction, while age, work on family conflict, family on work conflict, and job involvement all had statistically significant negative effects. Finally, perceptions of the level of financial rewards, job stress, organizational commitment, gender, race, educational level, tenure, supervisory status, position, marital status, and having children, all had non-significant associations with overall satisfaction with life.     

Forest Conservation,Value Conflict,and Interest Formation in a Honduran National Park*

Abstract We argue that attempts to superimpose park regulatory regimes on existing land uses in the tropics represent conflicts between alternative cultural models of natural resource management. The results of such conflicts are unique regulatory regimes emerging from distinctive processes that redefine the terms and limits of natural resource use. In creating a scarcity of available resources, parks encourage social differentiation and greater awareness of societal patterns of inequality, establishing a potential for the articulation of demands for social and environmental equity. We evaluate these claims with a case study of the Cerro Azul Meambar National Park in Honduras. We base our analysis on 54 indepth interviews of Park residents in five Park communities.     

The Age Difference Between Spouses: Variations among Developing Countries

Sub-national and cross-national variations in the age difference between spouses are investigated with data from the World Fertility Survey relating to 29 developing countries. Substantial variation within and between countries is evident. Analysis suggests that the relative age of prospective spouses is a factor taken into account in the marriage market. Observed variation in the age difference, within and between countries, cannot be explained as the simple by-product of the random matching of independently determined distributions of men's and women's ages at marriage. Certain age differences are avoided, others chosen more frequently. Preferred age differences appear to differ in the societies studied, however, and this variation can be directly interpreted in terms of two sets of factors: kinship structure and women's roles. The analysis also suggests that demographic determinants of the age difference, in particular age constraints on the pool of possible matches, are of less importance in explaining societal variations than are social structural factors.     

Inferences on the lognormal mean for complete samples

In many engineering problems it is necessary to draw statistical inferences on the mean of a lognormal distribution based on a complete sample of observations. Statistical demonstration of mean time to repair (MTTR) is one example. Although optimum confidence intervals and hypothesis tests for the lognormal mean have been developed, they are difficult to use, requiring extensive tables and/or a computer. In this paper, simplified conservative methods for calculating confidence intervals or hypothesis tests for the lognormal mean are presented. In this paper, “conservative” refers to confidence intervals (hypothesis tests) whose infimum coverage probability (supremum probability of rejecting the null hypothesis taken over parameter values under the null hypothesis) equals the nominal level. The term “conservative” has obvious implications to confidence intervals (they are “wider” in some sense than their optimum or exact counterparts). Applying the term “conservative” to hypothesis tests should not be confusing if it is remembered that this implies that their equivalent confidence intervals are conservative. No implication of optimality is intended for these conservative procedures. It is emphasized that these are direct statistical inference methods for the lognormal mean, as opposed to the already well-known methods for the parameters of the underlying normal distribution. The method currently employed in MIL-STD-471A for statistical demonstration of MTTR is analyzed and compared to the new method in terms of asymptotic relative efficiency. The new methods are also compared to the optimum methods derived by Land (1971, 1973).     

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.
