Distinguishing Features of Just-in-Time Systems in the Make-to-Order/Assemble-to-Order Environment*

Few studies of just-in-time (JIT) implementation examine their significance in make-to-order manufacturing environments. This study examines the relative importance of several operating variables that are characteristic features of JIT systems within such environments in North America. The results suggest that the most salient features of JIT for make-to-order and assemble-to-order firms are the elimination of waste (in the form of time and defects), reduced setup time, reduced lotsize, and a smaller pool of suppliers. In addition, the results suggest that the use of non-domestic suppliers can possibly hinder efforts at JIT implementation of materials procurement.     

Single-Parenthood and Poverty in Great Britain

ABSTRACT This paper examines empirically the relationship between single-parenthood and absolute poverty in Great Britain. Data from two years of the Family Expenditure Survey are used (1968 and 1986). A poverty measure that is additively decomposable with population share weights, and consistent with Sen's axiomatic approach to poverty measurement, is used to decompose the total amount of poverty into the “shares” accruing to different types of households (i.e. female and male single-parents, two-parent households and “other” types of households). Three main conclusions concerning the poverty experience of British single-parents emerge from the analysis. The first is that poverty rates for single-parent households are generally higher than the average for all households. However, this disadvantage is not as large as one might expect, especially when a comparison is made with two-parent households. The second is that single-parent households are over-represented in the ranks of the poor. That is, their “share” of total poverty is greater than their population share. The third is that increasing single-parenthood has had little impact on the overall trend in absolute poverty in the period 1968 to 1986.     

Master Scheduling in Assemble-To-Order Environments: A Capacitated Multiobjective Lot-Sizing Model

Basic characteristics of an assemble-to-order environment make effective master scheduling extremely difficult. Limited resource capacities and dynamic customer end-item demand contribute to the complexity of the master production scheduling problem. To gain flexibility and responsiveness within this system, the master production schedule (MPS) focuses at the component level. This research proposes a master scheduling technique for manufactured components which combines a multiobjective capacitated multi-item/multi-stage lot-sizing model with an interactive multiple objective optimization solution procedure. To evaluate the model's performance as a realistic and practical master scheduling tool, this study focuses on the National Cash Register (NCR) electronics manufacturing facility in Columbia, South Carolina.     

Translators, traitors, and traducers: Perjuring Hawaiian same-sex texts through deliberate mistranslation

In the long history of the West's encounter with Hawaiian culture, which began in the late 1700s with Captain Cook, translators and translations have often been the tools of intentional falsehood, thus demonstrating the truth of the Italian proverb, Traduttore, traditore ("the translator is a traitor")--particularly with regard to same-sex texts. The standards of truth have often been subverted in translation by the demands of foreign religion, hegemony, business, and academe. This subversion continues to this day in the form of the "missionary mentality" in politics and law. The way out of this situation is a brutally honest cleaning-off of the besmirched Hawaiian texts.     

From "Male Bonding Rituals" to "Suicide Tuesday": A qualitative study of issues faced by gay male ecstasy (MDMA) users

Use of MDMA and other club drugs has increased among gay men, but questions remain concerning the use, context, and popularity of these drugs; and views of their side effects. We interviewed in-depth 12 gay MDMA users in New York. MDMA had specific appeals to gay men, who often described isolation and stigmatization. Users underwent a period of initiation and social networks often became comprised of greater numbers of other users. Club environments fostered drug use and vice versa. Awareness of potential adverse effects varied and was minimized. Appropriate educational and prevention programs are needed to address these issues, and must take into account the specific contexts of these gay men's lives.     

在冲突中创造价值

精明的商业领袖会在冲突中寻找创造价值的时机无论在哪一行,总会有争吵。未按时交货;客户改变主意;合作伙伴不遵守承诺;部门的主管不批准某项预算而且还进行人身攻击。经理们对待这样的冲突和对待其他生意的方式往往是不同的。他们的做法完全不同,就好像解决冲突需要完全不同的方式:要不你获胜,要不我获胜。双

Policy-induced Innovation in Sub-Saharan African Agriculture: A Multilateral Malmquist Productivity Index Approach

To meet the [African] crisis one must turn to agricultural-led growth. But, based on historical experience, an agricultural-led strategy must be framed in no less than a twenty-year horizon and must entail a combination of technological innovation, policy reform, and institutional restructuring because each, by itself, is limited.

Cigarette Smoking and All-Cause and Cause-Specific Adult Mortality in the United States

This study illuminates the association between cigarette smoking and adult mortality in the contemporary United States. Recent studies have estimated smoking-attributable mortality using indirect approaches or with sample data that are not nationally representative and that lack key confounders. We use the 1990–2011 National Health Interview Survey Linked Mortality Files to estimate relative risks of all-cause and cause-specific mortality for current and former smokers compared with never smokers. We examine causes of death established as attributable to smoking as well as additional causes that appear to be linked to smoking but have not yet been declared by the U.S. Surgeon General to be caused by smoking. Mortality risk is substantially elevated among smokers for established causes and moderately elevated for additional causes. We also decompose the mortality disadvantage among smokers by cause of death and estimate the number of smoking-attributable deaths for the U.S. adult population ages 35+, net of sociodemographic and behavioral confounders. The elevated risks translate to 481,887 excess deaths per year among current and former smokers compared with never smokers, 14 % to 15 % of which are due to the additional causes. The additional causes of death contribute to the health burden of smoking and should be considered in future studies of smoking-attributable mortality. This study demonstrates that smoking-attributable mortality must remain a top population health priority in the United States and makes several contributions to further underscore the human costs of this tragedy that has ravaged American society for more than a century.
