Unification of some multivariate process capability indices for asymmetric specification region

In manufacturing industries, it is often seen that the bilateral specification limits corresponding to a particular quality characteristic are not symmetric with respect to the stipulated target. A unified superstructure of univariate process capability indices was specially designed for processes with asymmetric specification limits. However, as in most of the practical situations a process consists of a number of inter‐related quality characteristics, subsequently, a multivariate analogue of , which is called C_M(u,v), was developed. In the present paper, we study some properties of C_M(u,v) like threshold value and compatibility with the asymmetry in loss function. We also discuss estimation procedures for plug‐in estimators of some of the member indices of C_M(u,v). Finally, the superstructure is applied to a numerical example to supplement the theory developed in this article.     

In Sickness and in Health: Implications for Employers when Bipolar Disorders are Protected Disabilities

This paper explores the potential conflict between employment protections afforded to individuals with bipolar disorder, and employers’ obligations to maintain a safe working environment for others in the workplace. Both the Americans with Disabilities Act (ADA) and the Americans with Disabilities Act Amendments Act of 2008 (ADAA) provide workplace protections to those employees or applicants who are classified as qualified individuals with a disability. A disability is “a substantial impairment—a physical or mental impairment—in a major life activity that would substantially limit that major life activity.” ( 42 U.S.C. §§ 12102(1)(A)-(C)), and “mental impairment” is defined to include individuals with bipolar disorder (42 U.S.C. § 1630.2(h)(2)). These statutes further impose a requirement on employers to make reasonable accommodations for such individuals. In essence, they protect the bipolar employee from any discrimination in the workplace based on their disability, to include harassment by coworkers. However, employers may find themselves caught on the horns of a dilemma. Depending on the nature and severity of the bipolar employee’s conduct toward coworkers, they may also be exposed to liability for harm done to coworkers under negligent retention laws, or even the anti-harassment provisions of other equal employment statutes. If a bipolar employee’s negative behaviors toward coworkers are sufficiently severe or pervasive, they can result in coworkers suffering harassment sufficient to constitute actionable conduct under the ADA. To reduce exposure to litigation, employers must understand both their obligations under the ADA, and the nature of bipolar disorder.     

Connection between uniformity and minimum moment aberration

The issue of uniformity in symmetrical fractional factorial designs is studied in this paper. The so-called discrete discrepancy is employed as a measure of uniformity. In this paper we give linkages between uniformity measured by the discrete discrepancy and minimum moment aberration, which provide a significant statistical justification of the discrete discrepancy.     

The TUC’s Organising Academy: an assessment

In 1998 the British Trades Union Congress established an Organising Academy to train a new generation of paid union organisers. This article reviews the first two years of the Academy and offers an initial evaluation. It seeks to gauge whether the initiative has prompted innovation in organision policy in unions and led to successful organising outcomes.     

CREDIBILITY AND STRATEGIC LEARNING IN NETWORKS

We analyze a model of diffusion in a fixed, finite connected network. There is an interested party that knows the quality of the product being propagated and chooses an implant in the network to influence other agents to buy. Agents are either “innovators,” who adopt immediately, or rational. Rational consumers buy if buying instead of waiting maximizes expected utility. We consider the conditions on the network under which optimal diffusion of the good product with probability 1 is a perfect Bayes equilibrium.     

IT'S ABOUT TIME: EFFECTS OF THE AFFORDABLE CARE ACT DEPENDENT COVERAGE MANDATE ON TIME USE

We examine how the Affordable Care Act's dependent coverage mandate (DCM) affected young adults' time allocation. Exploiting more accurate measures from the American Time Use Surveys, we find that the DCM reduced labor supply. The question then arises, what have these adults done with the extra time? Estimates suggest a reduction in job‐lock, as well as in the duration of the average doctor's visit, including time spent waiting and receiving care. The latter effect is consistent with substitution from emergency‐department utilization toward more routine care. Estimates suggest that the extra time has gone into socializing, and into educational and job‐search activities. (JEL I1, J2, H0)     

Ecological modernisation: A reformist review

Few trends could so thoroughly undermine the very foundation of our free society as the acceptance by corporate officials of a social responsibility other than to make as much money for their stockholders as possible.     

Non-buoyant puff and plume dispersion modeling issues

This workshop was organized as a discussion group for a panel of dispersion modeling experts aimed at identifying and resolving (to whatever extent possible) the major debatable issues involved in the appropriate application and interpretation of dense gas dispersion models to real and potential scenarios.
