Legalization of drugs: Effects on the workplace

In the last few years bipartisan support for legalizing drugs has grown to a surprising level. Because of the lack of involvement of the business community in this debate, we surveyed the human resource managers of 127 firms about their perceptions of the effects of legalization. Their responses were uniformly negative, with expectations that drug use, absenteeism, worksite crime, and liability costs would increase, while the quality and quantity of work would decline. They also forecast increases in drug testing, performance monitoring, and education and rehabilitation programs as a result.     

OR vice: Forecasting and classification techniques for narcotics interdiction

Counternarcotics interdiction efforts have traditionally relied on historically determined sorting criteria or “best guess” to find and classify suspected smuggling traffic. We present a more quantitative approach which incorporates customized database applications, graphics software and statistical modeling techniques to develop forecasting and classification models. Preliminary results show that statistical methodology can improve interdiction rates and reduce forecast error. The idea of predictive modeling is thus gaining support in the counterdrug community. The problem is divided into sea, air and land forecasting, only part of which will be addressed here. The maritime problem is solved using multiple regression in lieu of multivariate time series. This model predicts illegal boat counts by behavior and geographic region. We developed support software to present the forecasts and to automate the process of performing periodic model updates. During the period, the model was in use at. Coast Guard Headquarters. Because of deterrence provided by improved intervention, the vessel seizure rate declined from 1 every 36 hours to 1 every 6 months. Due in part to the success of the sea model, the maritime movement of marijuana has ceased to be a major threat. The air problem is more complex, and required us to locally design data collection and display software. Intelligence analysts are using a customized relational database application with a map overlay to perform visual pattern recognition of smuggling routes. We are solving the modeling portion of the air problem using multiple regression for regional forecasts of traffic density, and discriminant analysis to develop tactical models that classify “good guys” and “bad guys”. The air models are still under development, but we discuss some modeling considerations and preliminary results. The land problem is even more difficult, and data collection is still in progress.     

Toddlers,teenagers, and terminal heights: the importance of puberty for male adult stature,Flanders, 1800–76

Does adult stature capture conditions at birth or at some other stage in the growth cycle? Anthropometrics is lauded as a method for capturing net nutritional status over all the growing years. However, it is frequently assumed that conditions at birth were most influential. Was this true for historical populations? This article examines the heights of Flemish men born between 1800 and 1876 to tease apart which moments of growth were most sensitive to disruption and reflected in final heights. It exploits two proximate crises in 1846–9 and 1853–6 as shocks that permit age effects to be revealed. These are affirmed through a study of food prices and death rates. Both approaches suggest a shift of the critical moment away from the first few years of life and towards the adolescent growth spurt as the most influential on terminal stature. Furthermore, just as height is accumulated over the growing years, conditions influencing growth need to be understood cumulatively. Economic conditions at the time of birth were not explanatory, but their collective effects from ages 11 to 18 years were strongly influential. At these ages, both health and nutrition mattered, to varying degrees. Teenagers, rather than toddlers, should be our guides to the past.     

'High-performance' Management Practices, Working Hours and Work–Life Balance

The effects of selected high‐performance practices and working hours on work–life balance are analysed with data from national surveys of British employees in 1992 and 2000. Alongside long hours, which are a constant source of negative job‐to‐home spillover, certain ‘high‐performance’ practices have become more strongly related to negative spillover during this period. Surprisingly, dual‐earner couples are not especially liable to spillover — if anything, less so than single‐earner couples. Additionally, the presence of young children has become less important over time. Overall, the results suggest a conflict between high‐performance practices and work‐life balance policies.     

Competition for goods in buyer-seller networks

Abstract. This paper studies competition in a network and how a network structure determines agents' individual payoffs. It constructs a general model of competition that can serve as a reduced form for specific models. The paper shows how agents' outside options, and hence their shares of surplus, derive from “opportunity paths” connecting them to direct and indirect alternative exchanges. Analyzing these paths, results show how third parties' links affect different agents' bargaining power. Even distant links may have large effects on agents' earnings. These payoff results, and the identification of the paths themselves, should prove useful to further analysis of network structure.     

Ready or Not? Homosexuality,Unit Cohesion,and Military Readiness

The U.S. military argues that homosexuals are unfit for service because their presence compromises military readiness and unit cohesion. Based on this assumption, it continues to discharge homosexuals at an average rate of approximately 925 per year. On the other hand, the extant research suggests that homosexuals are no more disruptive to military life than their heterosexual counterparts. By integrating the legal and scientific literature, this paper examines the soundness of the military’s assumptions and aims to improve our understanding of the issues involved. Within this context, the efficacy of the military’s “Don’t Ask, Don’t Tell, Don’t Pursue” policy and whether it is in the best interest of the military and its soldiers and sailors is discussed.

Devolution and disabled workers: the experiences of union equality representatives in Wales

In contrast to the Coalition Government, the Welsh Assembly embraced the original objectives of the Public Sector Equality Duty and provided financial support to develop a network of union equality representatives (ERs). With reference to ER support for disabled workers, this article examines the role of devolution in equalities bargaining.     

Death is not an option, how you die is--reflections from a career in oncology nursing

With a combined career of over 60 years in oncology nursing, the authors reflect on the critical elements in the question, "How can we afford to die?" Three high-profile patient scenarios in three different decades promised to improve use of advance directives but did not. Recent societal events, including the debates about health care reform, have brought attention again to end-of-life issues and care. Quickly approaching a "perfect storm" of an aging population, an inefficient and costly illness-oriented health care system, and health care profession shortages, the United States will not be able to afford delivering futile interventions. Nurses, who are consistently seen as the most trusted professionals, must take action in strategies the authors present.     

TACKLING THE ENDOGENEITY OF FERTILITY IN THE STUDY OF WOMEN'S EMPLOYMENT IN DEVELOPING COUNTRIES: ALTERNATIVE ESTIMATION STRATEGIES USING DATA FROM URBAN BRAZIL

Abstract

Opinions differ about whether family structure, especially fertility, should be considered endogenous in models of behavior in developing countries. Faced with a dearth of good instruments, mainstream researchers often urge working in reduced form and, therefore, losing variables of policy interest or limiting the type of questions they ask to those where good instruments are available. Rather than treating endogeneity as a yes or no characteristic, we suggest instead that researchers consider the likely magnitude of endogeneity bias before moving to reduced form. Facing a situation where endogeneity bias is often presented as a concern but where we expect little endogeneity bias, we tackle endogeneity using multiple econometric techniques not available to the average researcher. We find support for our hypothesis that little bias arises due to the assumption of exogeneity of recent fertility in a model of women's employment.
