The moderating effect of supply chain role on the relationship between supply chain practices and performance

Abstract: Purpose – The purpose of this paper is to examine the relationships between specific supply chain practices and organizational performance and whether this relationship is moderated by the role that a company assumes in its respective supply chain.Design/methodology/approach – This paper uses regression analysis and the relative weights method to analyze a set of survey data from respondents within the non‐academic, North American membership of the Institute of Supply Management.Findings – The results show that the supply chain role for a company makes a difference in terms of the specific supply chain practices that lead to better performance. Further, there is a clear indication that the relative importance of a specific practice varies across the supply chain roles thereby indicating that a general link between practice and performance may be erroneous without considering the specific context of the company concerned.Research limitations/implications – Supply chain practices are complex constructs.

Completeness in the Polynomial-Time Hierarchy A Compendium ∗

Abstract: We present a Garey/Johnson-style list of problems known to be complete for the second and higher levels of the polynomial-time Hierarchy (polynomial hierarchy, or PH for short). We also include the best-known hardness of approximation results. The list will be updated as necessary.

The Passions of Law

Abstract: The Passions of Law is the first anthology to treat the role that emotions play, don't play, and ought to play in the practice and conception of law and justice. Lying at the intersection of law, psychology, and philosophy, this emergent field of law scholarship raises some of the most profound and interesting questions at the heart of jurisprudence. For example, what role do emotions ranging from disgust to compassion play in the decision-making processes of judges, lawyers, juries, and clients? What emotions belong in which legal contexts? Is there a hierarchy of emotions, and, if so, through what sources do we identify it? To what extent are emotions subject to change or tutelage? How can we evaluate the role of emotion in such disparate contexts as death sentencing, laws about same sex marriage, hate crime legislation, punitive damages or shaming penalties? Consisting of original essays by leading scholars of law, theology, political science, and philosophy, The Passions of Law contributes to ongoing efforts to humanize law and reveals how this previously unacknowledged aspect of decision-making exerts a much greater impact on justice and the practice of law than most tend, or like, to think.

A Comparative Evaluation of Labor Tour Scheduling Methods

Abstract: This paper presents an initial study of relative performance for a number of the labor tour scheduling heuristic methods proposed in the literature. These heuristic methods were classified as either linear programming (LP) based or construction. Each of the methods was applied to a tour scheduling problem, subject to a variety of labor demand requirements distributions, with the singular objective being the minimization of total labor hours scheduled. Statistical analysis revealed that effective tour schedule solutions were generated by both LP-based and construction methods. Since the performances of the Keith [13], Morris and Showalter [18], and Bechtold and Showalter [5] methods were superior, their solutions were also compared across a number of secondary criteria. An overall analysis of the performances of these three methods resulted in the identification of a number of important managerial and decision-making issues. We conclude that service operations management should consider integrating these heuristic methods into a decision support system. Finally, suggestions for future research are provided.
