A global meaning of supply chain social sustainability

Abstract

The purpose of this research is to help reduce tensions in supply chain social sustainability (SCSS) decisions by providing a common global, contextual definition of social sustainability. This exploratory study utilised an inductive structured interview method to capture SCSS concept meanings. Those interviewed are from, have lived, and worked in developed economies, emerging economies and the base of the pyramid (BOP) economies. The results present a new global baseline definition of SCSS to inform theory and practice by finding that SCSS meanings differ not only between the different levels of economic development, but also within the levels as well. Culture, community and whether basic human needs are met all weigh into perspectives of what this concept is and should entail; a broad, contingent definition is most appropriate moving forward for sustainability planning and execution. Further research with stakeholders in more countries and communities is needed to validate our proposal.     

A sequential design for a clinical trial with a linear prognostic factor

We study a randomized adaptive design to assign one of the L$L$ treatments to patients who arrive sequentially by means of an urn model. At each stage n$n$, a reward is distributed between treatments. The treatment applied is rewarded according to its response, 0?_Yn?1$0?Y_n?1$, and 1-_Yn$1-Y_n$ is distributed among the other treatments according to their performance until stage n-1$n-1$. Patients can be classified in K+1$K+1$ levels and we assume that the effect of this level in the response to the treatments is linear. We study the asymptotic behavior of the design when the ordinary least square estimators are used as a measure of performance until stage n-1$n-1$.     

Testing citizen identities: Australian migrants and the Australian values debate

In this paper I explore how recent public debates about Australian values impact on the everyday lives of migrants preparing to become naturalised Australian citizens. Framed through the perspective of governmentality, I combine textual analyses of government documents relating to the Australian citizenship test with ethnographies of recently-arrived migrants in order to demonstrate how political practices related to the conferral of Australian citizenship link and interconnect with the production of migrant subjectivities. In this way, I explore what aspiring citizens think about Australian values and how they contest, accept and negotiate these demands on them to adopt the Australian way of life. The analysis suggests that migrants in this study presented multiple and complex ways of being model Australian citizens. They drew on popular national myths about Australianness promoted in citizenship test resources but they also produced alternative subjectivities that promoted identification with everyday multiculturalism as central to living a happy and prosperous life in Australia.     

Demographics,Public Spending and Social Programs

The demographic trends of the population of Italy are characterized by a very low fertility rate (in the 1990s the total fertility rate was 1.1–1.3, i.e. one of the lowest in the world) and very rapid aging (Italy was the first country in the world in which people aged 60+ outnumbered people aged less than 20). These trends require continuous and deep changes in the organization of society and in public services to avoid an increasing imbalance between demand and supply. They also require new social policies based on equity, efficiency and rationality.     

Lower posterior death probabilities from a quick medical response in road traffic accidents

Introduction: We use data from Spain on roads and motorways traffic accidents in May 2004 to quantify the statistical association between quick medical response time and mortality rate. Method: Probit and logit parameters are estimated by a Bayesian method in which samples from the posterior densities are obtained through an MCMC simulation scheme. We provide posterior credible intervals and posterior partial effects of a quick medical response at several time levels over which we express our prior beliefs. Results: A reduction of 5 min, from a 25-min response-time level, is associated with lower posterior probabilities of death in roads and motorways accidents of 24% and 30%, respectively.     

An alternative method for global and partial comparison of two diagnostic systems based on ROC curves

In this paper, an alternative method for the comparison of two diagnostic systems based on receiver operating characteristic (ROC) curves is presented. ROC curve analysis is often used as a statistical tool for the evaluation of diagnostic systems. However, in general, the comparison of ROC curves is not straightforward, in particular, when they cross each other. A similar difficulty is also observed in the multi-objective optimization field where sets of solutions defining fronts must be compared with a multi-dimensional space. Thus, the proposed methodology is based on a procedure used to compare the performance of distinct multi-objective optimization algorithms. In general, methods based on the area under the ROC curves are not sensitive to the existence of crossing points between the curves. The new approach can deal with this situation and also allows the comparison of partial portions of ROC curves according to particular values of sensitivity and specificity of practical interest. Simulations results are presented. For illustration purposes, considering real data from newborns with very low birthweight, the new method was applied in order to discriminate the better index for evaluating the risk of death.     

The Effects of E-journal Management Tools and Services on Serials Cataloging

Abstract

E-journal management tools and services such as MARC record services, A-to-Z lists, and link resolvers are changing e-journal cataloging. This column explores these changes in the academic environment through interviews with ten librarians representing eight universities. Three areas of change in serials cataloging are explored: (1) changes to the MARC record, including how libraries are adding/creating MARC records for their catalogs, the number and type of MARC records being created and linking within MARC bibliographic and holdings records; (2) the manner in which serials catalogers are being informed of changes; and (3) the evolving role of the serials cataloger. Future trends and advice for evolving workflow practices conclude the discussion.
