HIV and AIDS--employers grapple with difficult issues

HIV infection and AIDS pose special challenges to employers. Myriad laws affect how the employer must respond when an applicant or employee is infected with HIV or is ill due to AIDS. An overall compliance strategy should include thorough knowledge of those laws and a policy on HIV and AIDS, put in place before a crisis occurs.     

Spouses' materialism: Effects of parenthood status,personality type,and sex

This study responds to a call for broadened conceptualizations of materialism and its role in self-definition (Richins & Dawson, 1992). Data from 202 spouses were analyzed for relationships among materialism, parenthood status, and personality type, defined as spousal warmness or coolness (Csikszentmihalyi & Rochberg-Halton, 1981). Testable hypotheses were based on the concept of object-subject interchangeability (Claxton & Murray, 1994) as a mechanism of self-definition. The hypothesis was supported that cool spouses without children would have the highest materialism score. Total sample materialism scores were related to parenthood status and to several interactions among parenthood status, personality type, and sex of respondent. Analyzed by sex of respondent, men's materialism scores were related to parenthood status and to the interaction between parenthood status and personality type. Women's materialism scores were not related to any independent variables or interactions. Consumer policy implications are discussed.

Zusammenfassung Materialismus von Ehegatten: Effekte von Elternschaft, Persönlichkeitstyp und Geschlecht Die Studie reagiert auf die Forderung nach einer breiteren Konzeptualisierung der Materialismus-Variable und der Rolle von Materialismus bei der Selbst-Definition. Die Daten stammen von 202 Ehegatten und wurden auf die Beziehungen hin analysiert, die zwischen Materialismus, Elternschaft und Persönlichkeitstyp (definiert als eheliche WÄrme und eheliche Nüchternheit) bestehen. Die Hypothesen basieren auf dem Konzept der Objekt-Subjekt-Austauschbarkeit als Mechanismus der Selbst-Definition. BestÄtigt wurde die Hypothese, da\ nüchterne Ehegatten ohne Kinder den höchsten Materialismuswert haben. Insgesamt waren die Materialismuswerte abhÄngig von der Variable Elternschaft und von mehreren Wechselwirkungen zwischen Elternschaft, Persönlichkeitstyp und Geschlecht des Antwortenden. Eine geschlechtsspezifische Analyse zeigt, da\ die Materialismuswerte der MÄnner mit Elternschaft und mit der Wechselwirkung zwischen Elternschaft und Persönlichkeitstyp verbunden sind. Bei den Materialismuswerten der Frauen zeigte sich keine Beziehung zu einer der unabhÄngigen Variablen oder den Wechselwirkungen. Der Beitrag schlie\t mit einigen verbraucherpolitischen Implikationen.

Making competition in health care work

Health care reform in the United States is on a collision course with economic reality. Most proposals focus on measures that will produce one-time cost savings by eliminating waste and inefficiency. But the right question to ask is how to achieve dramatic and sustained cost reductions over time. What will it take to foster entirely new approaches to disease prevention and treatment, whole new ways to deliver services, and more cost-effective facilities? The answer lies in the powerful lessons business has learned over the past two decades about the imperatives of competition. In industry after industry, the underlying dynamic is the same: competition compels companies to deliver constantly increasing value to customers. The fundamental driver of this continuous quality improvement and cost reduction is innovation. Without incentives to sustain innovation in health care, short-term cost savings will soon be overwhelmed by the desire to widen access, the growing health needs of an aging population, and the unwillingness of Americans to settle for anything less than the best treatments available. The misguided assumption underlying much of the debate about health care is that technology is the enemy. By assuming that technology drives up costs, reformers neglect the central importance of innovation or, worse yet, attempt to slow its pace. In fact, innovation, driven by rigorous competition, is the key to successful reform.     

An investigation of cointegration and causality between fertility and female labour force participation

Both economists and demographers have long been interested in the nature of the relationship between fertility rate (BR) and female labor force participation (FR). Earlier work suggests an inverse relationship between BR and FR, except in preindustrial countries. The author applies Hsiao's version of the Granger causality method to examine the causality between BR and FR using transformed US data for the period 1948-93. An unidirectional causality is found to run from BR to FR with no feedback. These results confirm the hypothesis that the presence of small children discourages women from seeking employment outside of the home. Employment does not, however, affect a woman's decision to have children.     

Problem-solving in teaching/learning packages for Technology

In the project Technology in Secondary Education: Problem-solving in Teaching/learning Packages, two experiments regarding a construction problem and an explanation problem were conducted, in which two variants of a teching/learning package (strongly structuredvs. weakly structured) were compared. Only with the strongly structured instructional variant of the package for the explanation problem did the pupils come to a quick solution of the problem. In both experiments, the factors that influenced the problem-solving processes of the pupils were investigated. The results are of importance for curriculum developers and the authors of teaching/learning packages for Technology but further research into the factors influencing the problem solving process of pupils is necessary.     

The demographic cycle and optimal schooling choices

A model is developed that enables the authors to estimate the effects of demographic cycles on both earnings and schooling. The model is tested using data from the 1991 Korean Occupational Wage Survey. The results indicate that cohorts following large birth cohorts in the cycle choose relatively less formal schooling compared to pre-peak cohorts, and that post-peak cohorts also have lower incomes. This result concerning South Korea is consistent with findings from previous studies concerning the United States.     

Strategy and the new economics of information

We are in the midst of a fundamental shift in the economics of information--a shift that will precipitate changes in the structure of entire industries and in the ways companies compete. This shift is made possible by the widespread adoption of Internet technologies, but it is less about technology than about the fact that a new behavior is reaching critical mass. Millions of people are communicating at home and at work in an explosion of connectivity that threatens to undermine the established value chains for businesses in many sectors of the economy. What will happen, for instance, to dominant retailers such as Toys "R" Us and Home Depot when a search through the Internet gives consumers more choice than any store? What will be the point of cultivating a long-standing supplier relationship with General Electric when it posts its purchasing requirements on an Internet bulletin board and entertains bids from anybody inclined to respond? The authors present a conceptual framework for approaching such questions--for understanding the relationship of information to the physical components of the value chain and how the Internet's ability to separate the two will lead to the reconfiguration of the value proposition in many industries. In any business where the physical value chain has been compromised for the sake of delivering information, there will be an opportunity to create a separate information business and a need to streamline the physical one. Executives must mentally deconstruct their businesses to see the real value of what they have. If they don't, the authors warn, someone else will.
