A Multifactorial Risk Prioritization Framework for Foodborne Pathogens

We develop a prioritization framework for foodborne risks that considers public health impact as well as three other factors (market impact, consumer risk acceptance and perception, and social sensitivity). Canadian case studies are presented for six pathogen‐food combinations: Campylobacter spp. in chicken; Salmonella spp. in chicken and spinach; Escherichia coli O157 in spinach and beef; and Listeria monocytogenes in ready‐to‐eat meats. Public health impact is measured by disability‐adjusted life years and the cost of illness. Market impact is quantified by the economic importance of the domestic market. Likert‐type scales are used to capture consumer perception and acceptance of risk and social sensitivity to impacts on vulnerable consumer groups and industries. Risk ranking is facilitated through the development of a knowledge database presented in the format of info cards and the use of multicriteria decision analysis (MCDA) to aggregate the four factors. Three scenarios representing different stakeholders illustrate the use of MCDA to arrive at rankings of pathogen‐food combinations that reflect different criteria weights. The framework provides a flexible instrument to support policymakers in complex risk prioritization decision making when different stakeholder groups are involved and when multiple pathogen‐food combinations are compared.     

Nothing Matters

This essay reads Miller reading literature and zero, zero in literature, tracing how a doubling at the heart of zero is echoed in Miller's work. Miller's fascination and engagement with literature as otherness invokes the ambiguity of the sign O, sharing its figure with a figure that isn't a figure, impossibly at once letter and numeral, now converging in Miller's text on zero in literature. Literature, like zero, like the lover, like the Other, incessantly invites analysis only to elude understanding. Nothing matters because it is a place of slippage, playfully unsettling our most deeply ingrained beliefs.     

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.
