Eco-efficient supply chain networks: development of a design framework and application to a real case study

This paper presents a supply chain network design framework that is based on multi-objective mathematical programming and that can identify ‘eco-efficient’ configuration alternatives that are both efficient and ecologically sound. This work is original in that it encompasses the environmental impact of both transportation and warehousing activities. We apply the proposed framework to a real-life case study (i.e. Lindt & Sprüngli) for the distribution of chocolate products. The results show that cost-driven network optimisation may lead to beneficial effects for the environment and that a minor increase in distribution costs can be offset by a major improvement in environmental performance. This paper contributes to the body of knowledge on eco-efficient supply chain design and closes the missing link between model-based methods and empirical applied research. It also generates insights into the growing debate on the trade-off between the economic and environmental performance of supply chains, supporting organisations in the eco-efficient configuration of their supply chains.     

Effects of receipt of Social Security retirement benefits on older women’s employment

Labor force participation of women has declined since 1999; however, labor force participation of women 62+ has increased. The 2000–2006 waves of Health and Retirement Study (HRS) data, the initial years of the continuing upward trajectory, were used to test the effects of receipt of Social Security retirement benefits on older women’s employment. The models tested: (a) the effect of receipt of Social Security retirement benefits on whether employed; and (b) for women receiving Social Security retirement benefits, the effect of age elected receipt of benefits on whether employed. Both models included the effects of human capital characteristics and income sources. Receipt of Social Security benefits, pension income, and current age reduced the likelihood of employment; while educational level, good to excellent health, and nonmarried marital status increased the likelihood of employment. The older the woman was when she elected Social Security benefits, the more likely she was to be employed.     

Break-out im türkischen Lebensmittelhandel

Based on a qualitative-empirical study of the Turkish food retail sector in Vienna, this article discusses the social embeddedness of break-out-processes. In socio-scientific literature, the term “break-out” is used to describe the process by which immigrant entrepreneurs leave their “ethnic enclave economy” by gaining consumers beyond their own community. While research appears to reduce break-out to an individual and economically driven marketing strategy, the social dimension has been neglected so far. Our findings demonstrate that the entrepreneurs’ market orientation is located between the contradictory contexts of different expectations—those of the immigrant community as well as those of the majority community. On basis of a typology of different ways of dealing with these expectations we want to reveal the interrelationships between economic and social factors and, furthermore, to contribute to a deeper understanding of the social embeddedness of immigrant economies.     

The Seduction of the Surface: From Alice to Crash

Drawing on a qualitative analysis of Swedish newspaper debates in 1979 and 1995, this article examines how Swedish newspapers refer to biological sex difference as central to drinking practices. The study shows that women are a special category of concern in debate about gender and drinking in both 1979 and 1995. Further, it shows that Swedish newspapers draw upon biology in different ways in the two years. In 1979, debate about drinking during pregnancy and Fetal Alcohol Syndrome (FAS) is central and newspapers link biomedical research on FAS to the moral idea that mothers do anything to avoid harm to children. In 1995, debate about girls' drinking habits is central and newspapers link sex hormones and neurotransmitters to the moral idea that girls shouldn't “drink like men.” These differences are discussed in the context of Swedish media interest in evolutionary psychology and biomedical solutions to alcohol problems during the 1990s.     

Crawling is Associated with Mental Rotation Ability by 9‐Month‐Old Infants

The present experiment examined whether 9‐month‐old infants’ mental rotation ability was related to their crawling ability. Forty‐eight 9‐month‐old infants were tested; half of them crawled for 7.1 weeks on average. Infants were habituated to a video of a simplified Shepard–Metzler object rotating back and forth through a 240° angle around the longitudinal axis of the object. Infants were tested with videos of the same object rotating through the previously unseen 120° angle and with the mirror image of that display. The results showed that the crawlers looked significantly longer at the mirror object than at the familiar object. The results support the interpretation that crawling experience is associated with 9‐month‐old infants’ mental rotation ability.     

Max-stable processes for modeling extremes observed in space and time

Max-stable processes have proved to be useful for the statistical modeling of spatial extremes. For statistical inference it is often assumed that there is no temporal dependence; i.e., that the observations at spatial locations are independent in time. In a first approach we construct max-stable space–time processes as limits of rescaled pointwise maxima of independent Gaussian processes, where the space–time covariance functions satisfy weak regularity conditions. This leads to so-called Brown–Resnick processes. In a second approach, we extend Smith’s storm profile model to a space–time setting. We provide explicit expressions for the bivariate distribution functions, which are equal under appropriate choice of the parameters. We also show how the space–time covariance function of the underlying Gaussian process can be interpreted in terms of the tail dependence function in the limiting max-stable space–time process.     

Black Teenage Mothers' Understandings of the Effects of Maltreatment on their Coping Style and Parenting Practice: A Pilot Study

This article discusses a qualitative pilot study conducted with Black teenage mothers affected by maltreatment histories, exploring the feasibility of researching how they develop insights into the effects on their parenting skills. The results indicate key impact areas, including their relationships with their carers, perceptions of significant relationships and increased vulnerability to relationship abuse. As the young mothers resisted seeing themselves as victims and utilised an avoidance‐centred coping strategy, their ability to recognise the impact of harmful childhood experiences was limited. The article concludes with reflections on the pilot study's implications and limitations.     

Where are the children? Exploring the boundaries between text and context in the study of place and space in four different countries

In this article, we demonstrate how the cultural conceptions of a team of five researchers from different cultural and national backgrounds can be used as a source of knowledge during a collective, self‐reflexive analytical process. While collectively analysing texts describing daily life produced by first‐grade children and their parents in China, Norway, South Africa and the United States, the research team engaged in a collectively negotiated analytical process, which we refer to as an ‘analytic negotiating method’. The strength of this process rests on the ability to examine critically the boundaries between the researcher's contextual conceptions and conceptions derived from the texts. Engaging in this kind of negotiated analytical process contributes to scholarship by working towards a level of self‐reflexivity that makes the link between empirical data and researcher interpretation more transparent and produces a sensitivity to context that allows insights into the conceptions of childhood that operate cross‐culturally.     

Scholarly leadership of the study of leadership: A review of The Leadership Quarterly's second decade, 2000–2009

In a reprise of Lowe and Gardner's (2000) review of The Leadership Quarterly's (LQ) first decade as a premier outlet for scholarly leadership research, we review 353 articles published in LQ during its second decade. Multiple methods were employed to prepare this review, including: interviews with the journal's current Senior Editor and Associate Editors; an assessment of LQ's impact, reputation, and most cited articles through citation analyses; a content analysis of article type (theory, empirical, and methods), contributors (e.g., discipline, nationality, and institutional affiliation), theoretical foundations, research strategies, sample location/type, data collection methods, and analytical procedures; survey and follow-up focus groups conducted with LQ Editorial Review Board members; and qualitative analyses to assess the prevalent themes, contributions, and trends reflected in LQ during its second decade. Drawing from these sources, we describe anticipated directions for future research.
