Supply Chain Scheduling: Distribution Systems

We study conflict and cooperation issues arising in a supply chain where a manufacturer makes products which are shipped to customers by a distributor. The manufacturer and the distributor each has an ideal schedule, determined by cost and capacity considerations. However, these two schedules are in general not well coordinated, which leads to poor overall performance. In this context, we study two practical problems. In both problems, the manufacturer focuses on minimizing unproductive time. The distributor minimizes customer cost measures in the first problem and minimizes inventory holding cost in the second problem. We first evaluate each party's conflict, which is the relative increase in cost that results from using the other party's optimal schedule. Since this conflict is often significant, we consider several practical scenarios about the level of cooperation between the manufacturer and the distributor. These scenarios define various scheduling problems for the manufacturer, the distributor, and the overall system. For each of these scheduling problems, we provide an algorithm. We demonstrate that the cost saving provided by cooperation between the decision makers is usually significant. Finally, we discuss the implications of our work for how manufacturers and distributors negotiate, coordinate, and implement their supply chain schedules in practice.     

“Starting Points Matter”: Humanizing Economics Pedagogy through New Economic Paradigms

Abstract

This paper considers the implications of the neoclassical dominant narrative in economics education and conceptualizes specific responses that teachers and teacher educators can take to promote a humanizing economics pedagogy. I briefly describe alternative economic paradigms and contrast them with neoclassical fundamentals. Then, I include economic lesson ideas to showcase ways to teach traditional economic content in ways that attend to neoclassicism but expand the potential of the discipline into new paradigms. By interrogating the fundamentals of neoclassical economics, students and teachers of economics can use these new economic paradigms to foster a counternarrative that is more critical and humanizing and can help address the prevailing themes of an era marked by systemic oppression.     

Re-aligning the Stakeholders in Management Research: Lessons from Industrial, Work and Organizational Psychology

The publication of the Starkey and Madan (2001) report represents a timely and valuable contribution to an ongoing debate across a range of applied disciplines, concerning the nature and purpose of social research. The call for stakeholder alignment, culminating in the production of new knowledge that is both theoretically and methodologically rigorous on the one hand, and socially relevant on the other, is, in our view, to be greatly welcomed. However, the Mode 2 approach advocated by Starkey and Madan will not satisfy these fundamental requirements. Drawing on recent analyses of the nature, causes and consequences of the academic-practitioner divide in the subfield of industrial, work and organizational psychology, we offer an alternative, four-fold taxonomy of the varieties of managerial knowledge. Within our alternative framework, research that is low on rigour but high on relevance (a likely consequence of the wholesale adoption of a Mode 2 approach) is characterized as 'Popularist Science'. 'Pedantic Science', by contrast, is high on rigour but low on relevance, while 'Puerile Science' meets neither requirement. Only 'Pragmatic Science' will meet the twin imperatives of rigour and relevance. Whilst it is highly desirable that Pragmatic Science should dominate the management field, there are considerable barriers that impede its widespread adoption at the present time, not least the limited availability of researchers who possess the requisite sociopolitical and methodological competencies. The immediate imperative that has to be addressed, therefore, is the question of how best to close this competency gap, a fundamental precondition of stakeholder realignment.     

Shareholder Value and the Transformation of the U.S. Economy, 1984–20001

Using data from 62 U.S. industries for 1984–2000, this article explores the connections between shareholder value strategies, such as mergers and layoffs, and related industry‐level changes, such as de‐unionization, computer technology, and profitability. In line with shareholder value arguments, mergers occurred in industries with low profits, and industries where mergers were active subsequently saw an increase in layoffs. Industries with a high level of mergers increased investment in computer technology. This technology displaced workers through layoffs and was focused on reducing unionized workforces. Contrary to shareholder value arguments, there is no evidence that mergers or layoffs returned industries to profitability.     

Defrocking dualism: A new approach to defining industrial sectors

In this paper we argue that a division of the economy into core and periphery sectors does not do justice to the complexity of the structure of the U.S. economy. The dualistic approach is inadequate both theoretically and empirically. While the dual economy literature has utilized multiple concepts it has conceived of them as forming a single dimension. We develop additional concepts from the complex organizations literature and utilize this enlarged set of concepts in a truly multidimensional framework. We also present a new technique of categorization based on a combination of factor and cluster analyses. The resulting categorization is highly interpretable, and it is superior to previous operationalizations in that it fully reflects the multidimensionality of economic segmentation.     

Pragmatism and the study of large-scale social phenomena

Pragmatism has recently gained ground as a theoretical perspective in sociology. The approach is not without its critics, however. One common charge is that pragmatism is oriented toward the micro and not well suited for the explanation of meso- or macro-level events, processes, or outcomes. In this paper—a review essay—I consider whether the charge has merit. I examine four studies that draw heavily on pragmatism and give some indication of its explanatory potential. Taken together, these studies suggest that pragmatism has much to offer analysts of large-scale social phenomena. At the same time, key issues remain to be worked out.     

The attraction to sexual aggression scale: Part two

In this second article of a two‐part series, data from three separate studies are presented supporting the reliability, discriminant, and construct validity of the Attraction to Sexual Aggression (ASA) scale. Higher scores on this scale were associated with attitudes supporting aggression against women, affective reactions to media portrayals of forced sex, physiological and self‐reported sexual arousal, hostility toward women, dominance motives, and antisocial personality characteristics. Based on data with low sexual aggressors, higher ASA scores were associated with greater similarity (on relevant dimensions) to high sexual aggressors, suggesting that ASA may help identify potentially sexually aggressive men at “risk” for future sexual coercion. However, caution in the use of such identification is urged. Finally, it is concluded that although the data support the usefulness of earlier work with self‐reported likelihood measures, the use of ASA is an improvement in this line of research. Directions for future development of this scale and research are also discussed.     

Insights on medical tourism: markets as networks and the role of strong ties

Despite a huge amount of speculation and expectation surrounding medical tourism, hard empirical evidence is only now beginning to emerge. This paper widens the focus of discussion by contrasting two country experiences (UK and Korea) which on the surface illustrate the diversity of medical tourism and little else. However, considered more comparatively, the accounts contribute toward wider, albeit tentative, theoretical understandings, and insights. The paper is drawn from two broad programs of empirical study conducted over three years in UK and Korea, respectively. The article is structured in three parts: first, a brief overview of policy, legislative, and accreditation frameworks that exist to govern medical tourist flows. Second, we present evidence around flows, demographics, treatment, and medical tourism for Korea and UK (both for supply and demand). Third, we examine conceptual and theoretical implications of this evidence. We argue that viewing medical tourism as a global market is problematic; some medical tourist markets are best viewed as networks with long-term exchange relationships; some specific areas of activity do function more strongly as price-related; decision making around medical tourism frequently involves a range of information and social networks (economic action as embedded social structure); and medical tourism is a function of globalization.
