Strategic Purchases of Bundled Products in a Health Care Supply Chain Environment*

Recent articles in the Wall Street Journal summarize the state of business practice in American hospitals by shedding light on the state of supply chain management practices and foci in today's health care supply chains. In health care, the single largest cost after labor is materials, and it has been documented that health care facilities can reduce the environmental impacts of the products and services they consume before regulatory problems arise or waste disposal costs increase by focusing on their upstream activities. Health care systems around the country consume significant quantities and varieties of products within the health delivery processes. Solving these environmental problems requires a much broader view involving collaborative efforts of professionals from different areas of health care to meet these challenges. The purchasing function bridges the gaps by providing a healthy dialogue on key environmental attributes within the health care supply chain. The concept of bundling new with refurbished products is gaining a lot of attention in the health care supply chain. This research describes a health care purchasing problem for bundling new and refurbished products of the type facing a growing number of large health care providers, and then proposes a methodology for evaluating the complex tradeoffs involved in bundling decisions for refurbished health care products. By exploiting some useful properties of the problem structure, our results provide buyers with useful insights for examining and selecting suppliers who are willing to offer bundles of new and refurbished products.     

CSR and Accounting: Drawing on Weber and Aristotle to Rethink Generally Accepted Accounting Principles

The purpose of this article is to discuss and provide an alternative, less materialist–individualist approach to interpret the four assumptions of generally accepted accounting principles: economic entity, unit measure, periodic reporting, and going concern. The article draws from and builds on arguments first developed by Weber and Aristotle to demonstrate how a materialist–individualist moral point of view influences the conventional interpretation of the four basic assumptions for generally accepted accounting principles. We then propose an ideal‐type conceptual framework upon which to critique mainstream accounting theory and to develop alternative accounting theory that balances multiple forms of well‐being (including financial, but also social, physical, spiritual, and ecological well‐being) for multiple stakeholders (including owners, employees, customers, suppliers, competitors, neighbors, future generations, and so forth).     

Reducing Palilalia by Presenting Tact Corrections to Young Children with Autism

Palilalia, the delayed repetition of words or phrases, occurs frequently among individuals with autism and developmental disabilities. The current study used a combined multiple baseline and reversal design to investigate the effectiveness of presenting tacts as corrections for palilalia. During baseline, five preschoolers with autism emitted high rates of palilalia and low rates of mands and tacts during play and instructional activities. During treatment, when experimenters presented opportunities to echoically tact actions and objects following the emission of palilalia, its frequency decreased to low and stable levels and mands and tacts increased. Functional relationships between the tact corrections and emissions of palilalia, mands, and tacts were established during reversals to baseline and treatment conditions. Similar trends in responding were found for frequency of palilalia, mands, and tacts in non-treatment settings.     

Automated manufacturing—Why is it taking so long?

There are strong forces directed towards automated manufacturing with great potential for increases in productivity and efficiency. However, despite these forces, there are barriers preventing the rapid adoption of the new technologies. The author analyses these factors in relation to a study which aimed to identify market opportunities over the next decade in relation to the developments in microtechnology.     

The state of applied demography in Australia

What is the state of applied demography in Australia from a practitioner’s perspective? The paper discusses this question by addressing the following aspects: what issues are and are not receiving media coverage; the use and misuse of demographic data; the level of service received by the demography community from the main suppliers of data; the emerging role of some key players on the scene and some suggestions on the teaching of demography in Australia.     

Social factors in facial display and communication: A reply to Chovil and others

This paper discusses the Chovil (1991) study, questioning the assumption that the notion of facial display as communication is incompatible with that of facial display as readout of motivational/emotional response. It is argued that (a) the Chovil paper oversimplifies the view of the competition; (b) social factors can facilitateor inhibit expression depending upon the nature of the emotion being expressed and the expressor's personal relationship with the other; and (c) social factors produce strong social emotions, so that any manipulation of sociality must also manipulate emotion.Preparation of this paper was supported in part by NIMH grant MH-40753 to Ross Buck, and by the University of Connecticut Research Foundation.     

Tandem Configuration Automated Guided Vehicle Systems: A Comparative Study*

Automated guided vehicle (AGV) systems provide the flexibility and integration required for flexible manufacturing systems. Previous AGV system studies have attempted to reduce the controlling complexities commonly encountered in these systems. However, this has not been accomplished without additional resources (e.g., automated guided vehicles) and lower system flexibility. The primary objective of this study is to compare the performance of AGV system configurations that reduce controlling and modification complexities (i.e., tandem configurations) to traditional AGV system configuration. Three AGV system configurations were tested under 16 experimental conditions. Performance metrics considered were AGV utilization, mean flowtime, mean tardiness, and percent tardy. The results of this study extend the findings of the previous studies in demonstrating the viability of tandem configurations, in that the tandem configurations match the performance of traditional configuration across all performance metrics, without sacrificing ease of control and system flexibility. Finally, the cost tradeoffs inherent in selecting a particular configuration are discussed.     

Until work do us part: Labour migration and occupational stratification in non-cohabiting marriage

While recent decades have seen considerable research on cohabitation without marriage, the study of marriage without cohabitation has not fared as well. Prior work on the latter has emphasized the importance of occupational stratification, but ignored the social context around occupation, particularly regarding labour mobility and economic development. In this paper, we outline the significance of contemporary labour mobility and concomitant occupational stratification for the risk of non-cohabiting marriage, and use data from the IPUMS–International project to provide a cross-national accounting of non-cohabiting marriage. We focus on two issues: first, how does prevalence vary across countries, across time, and with respect to economic development? Second, how do the core dynamics of labour mobility—including migration, occupational status, and economic development—influence the probability of non-cohabiting marriage? Results indicate broad cross-national differences in prevalence, increasing risk over time, and a pattern of accumulating risk associated with multifaceted social disadvantage.     

Of talk,economics, love and innovation

Few economists speak of talk in considering human interaction. Deirdre McCloskey is one who does. The paper considers what it means to take talk seriously, its connection to moral philosophy, and to innovation.
