Emerging paradoxes in executive leadership: A theoretical interpretation of the tensions between corruption and virtuous values

The recent mini scandal surrounding questionable on-line postings of John Mackey, the founder and CEO of Whole Foods Market Inc., raises once again ethical challenges related to contemporary business leadership. Given his visible commitment to environmentally sound strategies and other responsible business practices, Mackey’s actions epitomize the irony and paradox that can surround executive leadership ethics. While this essay acknowledges the potential role of stricter legal constraints, punishments for offenders, decentralized governance systems, and rationalized structures that help prohibit power abuse, it views such rationalistic considerations alone to be inadequate. Rather, the authors suggest that the promotion of authentic virtuousness is an often overlooked yet indispensable part of any meaningful long term ethical leadership process.     

Modified maximum likelihood estimation for rayleigh distribution

For defining a Modified Maximum Likelihood Estimate of the scale parameter of Rayleigh distribution, a hyperbolic approximation is used instead of linear approximation for a function which appears in the Maximum Likelihood equation. This estimate is shown to perform better, in the sense of accuracy and simplicity of calculation, than the one based on linear approximation for the same function. Also the estimate of the scale parameter obtained is shown to be asymptotically unbiased. Numerical computation for random samples of different sizes from Rayleigh distribution, using type I1 censoring is done and is shown to be better than that obtained by Lee et al. (1980)     

Inventory Planning for a Modular Product Family

This paper is motivated by observing that an increasing number of firms are offering modular products assembled with multiple option choices for the consumer. Starting with the PC offerings by Dell which allowed (and still allows) users to configure their product by choosing among multiple choices for each option, the current market place seems to have evolved to a make‐to‐stock scenario where Apple offers its IPAD series with multiple models each with a unique storage size, color, and wireless chip technology. The focus of our work is on determining the optimal stocking level of modular end‐products. Our analysis is based on a benchmark model with the aim of maximizing expected profit subject to an aggregate fill rate constraint as well as variant‐specific individual fill rates under a make‐to‐stock setting. To further assess the robustness of our finding, we consider the extensions of correlated market preferences over options, price‐dependent demand, and alternative probability distributions for characterizing uncertainty in market preferences or aggregate demand. Finally we also show how to extend the single period model into a multiple‐period setting. Through extensive computational analysis, we find that more precise estimates of market preferences for various modular options constitute extremely valuable information that goes beyond the usefulness of forecasts of aggregate market demand. From a practical perspective, this might be indicative of another classic marketing‐operations trade‐off. Offering more options for consumers would be preferred by marketing managers since this would reach more consumers and hence, enhance product sales. On the other hand, the ability to obtaining greater forecast accuracy would decline when the number of options increase. Hence, from an operational perspective, it would be preferred to limit option choices (so that better forecasts can be obtained) since this would lead to lower stocking costs and hence, higher profits.

Assessment of systemic greenness: a case study of tyre manufacturing unit

Abstract

In this paper, we develop an assessment framework to evaluate the systemic greenness of a tyre manufacturing unit by capturing the interactions between the green practices implemented. By reviewing the existing literature, we propose a stakeholder-based green practices framework comprising of operation strategy practices, process practices, employee practices, regulatory practices, customer practices, competition practices, social practices, and supplier practices. The empirical data on the interactions of green practices between and within stakeholders are collected by conducting a detailed case study of a large radial tyre manufacturing unit in India. We use graph-theoretic approach to incorporate the interactions between different green practices and assess the systemic greenness of the case organisation. Based on the systemic greenness attained, we rank the green practices within stakeholders and also between the stakeholders. We conduct scenario analysis to develop a systemic greenness index and a scale to assist practitioners in evaluating and benchmarking the greenness performance. We also discuss implications for theory and practice along with the inherent limitations.     

Multicultural Democracy: Toward a better democracy

Multicultural democracy incorporates socio-economic, cultural, and political diversity and goes beyond current conceptions of democracy. It begins by asking these critical questions: Who is and is not participating in democracy and on whose terms? And how wide is the path to participation? These questions serve as a foundation for exploring the three tenets of multicultural democracy: democracy as a path, membership in both large and small publics, and diversity as essential. After explaining the theory of multicultural democracy, I examine the extent to which critical pedagogy, building of community, and thorough disciplinary content contribute to classroom-based multicultural democracy.     

Comparison at 32–37 Weeks Postconception of Infants Born 1983–1989 and 1995–2004 on the Neurobehavioral Assessment of the Preterm Infant

In spite of numerous recent outcome studies of extremely low birth weight (ELBW) infants, no data exist on their development prior to term. In this study we traced and compared the neurobehavioral development of 251 ELBW (< 1,000 g) and 240 low birth weight (LBW; 1,000 g–2,500 g) preterms born between 1995 and 2004 from 32 to 37 weeks postconceptional age (PCA), using the Neurobehavioral Assessment of the Preterm Infant (NAPI Korner & Thom, 1990). Compared to the original NAPI cohort of 521 infants (born 1983–1989), the ELBW and LBW infants were at higher medical risk, displayed weaker motor development, a tighter scarf sign and popliteal angle at all or most PCAs, and a weaker cry at older PCAs; they did not differ in irritability and percent asleep ratings. Few differences were noted between the ELBW and LBW groups. Research is now needed to determine whether the 1995 to 2004 NAPI values of ELBW and LBW infants at 32 to 37 weeks PCA are predictive of later outcome of high‐risk preterms.     

Older People’s Conceptualization of Abuse: A Systematic Review

The concept of elder abuse is a relatively recent one, and there is ongoing debate around its definition and interpretation. Policy in America, the United Kingdom, and Ireland has been criticized as being professionally driven and therefore paternalistic and disempowering. Little is known about older people’s understanding of the term “abuse” or the behaviors that they deem to be abusive. In this systematic review, eight databases were searched using agreed-upon criteria, and the results were assessed for relevance. Fifteen studies were included and are discussed under the themes of caregiving, domestic violence, society, abusive acts, and thresholds.     

Sequencing questions to ferret out terrorists: Models and heuristics

Consider the problem of granting boarding clearance for a large population of air travelers while ferreting out any potential terrorists and denying them entry, in a short time. It is assumed that the probability of having a terrorist in the group is very small. Further assume that the process consists of asking a series of questions and the decision to clear or deny is dependent on the answer set. An efficient sequencing of the questions may reduce the number of questions needed to be asked in order to reach a decision. This problem is modeled as a question sequencing problem. The problem is intrinsically hard and hence we develop two approaches to solving the problem. The first uses a traditional greedy heuristic approach exploiting the relationship between answers and the outcome. The second adopts the decision tree approach used in classification problems to this problem. We also report on the performance of the two heuristics which does exceptionally well on problems with a very low probability of occurrence.     

Structuring Supplier Involvement in New Product Development: A China–U.S. Study

Buying and supplying organizations rely on each other for developing better products in an efficient manner, which explains the popularity of involving suppliers in new product development (NPD). However, such involvement is not always successful, partially due to the challenges of structuring a buyer–supplier team to manage joint dependence and dependence asymmetry. This study adopts an organizational dependence view to examine how three types of intergroup structures—administrative (formalization and centralization), task (task interdependence), and physical (colocation)—influence project performance and buyer learning in NPD projects. Furthermore, adopting a contingency theory perspective, we study whether the national context moderates the effects of intergroup structures on project outcomes. We adopt a two‐group structural equation modeling approach to test hypotheses with survey responses from a sample of NPD projects in the United States (US) and China. Results show different ways in which intergroup structures influence project performance and buyer learning in the two culturally, economically, and institutionally distinct countries. We discuss the implications of these new findings and present directions for future research.
