A model-driven DSS architecture for delivery management in collaborative supply chains with lack of homogeneity in products

Uniform product deliveries are required in the ceramic, horticulture and leather sectors because customers require product homogeneity to use, present or consume them together. Some industries cannot prevent the lack of homogeneity in products in their manufacturing processes; hence, they cannot avoid non-uniform finished products arriving at their warehouses and, consequently, fragmentation of their stocks. Therefore, final uniform product amounts do not match planned production ones, which frequently makes serving previous committed orders with homogeneous quantities impossible. This paper proposes a model-driven decision support system (DSS) to help the person in charge of delivery management to reallocate the available real inventory to orders to satisfy homogenous customer requirements in a collaborative supply chain (SC). The DSS has been validated in a ceramic tile collaborative SC.     

Labour supply effects of a cash-for-care subsidy

From 1999, all parents in Norway with children aged one to three, who did not attend publicly subsidised daycare, became eligible for a cash-for-care (CFC) subsidy. One effect of the CFC-subsidy was to increase in the relative price of external child care. This article analyses whether the CFC-subsidy has led to a reduction in the labour supply of mothers. A framework for evaluating policy reforms when reforms are equally and nation-wide accessible is put forward. The results show that the CFC-subsidy has reduced womens labour supply. The results are sustained after controlling for contemporaneous macroeconomic shocks, using a triple difference approach.The author thanks Hege Torp, Erling Barth and Harald Dale-Olsen at The Institute for Social Research, as well as participants at the European Society for Population Economics (ESPE) conference in Bilbao in June 2002, participants at the Lunch-seminar at Statistics Norway, and two anonymous referees for valuable comments.

Current Challenges of North/South Relations in Gay-Lesbian and Queer Studies

ABSTRACT

The article assesses and analyzes different dimensions of the current configuration of North/South dialogues within gay-lesbian and queer studies, with particular attention to the interrelations between the United States and South America. It looks into how gay-lesbian and queer studies relate to the global division and hierarchy of intellectual labor traditionally embedded in academic practices, and it asks whether the scope of its radical program includes a revision of unequal academic dynamics. Its concerns are both ethical and epistemological, as they speak not only to the moral and political dimensions of academic practice, but also to how these modes affect the knowledge produced in the United States and in South America today. By offering a view from the South conversant with South American as well as Northern production, we hope to contribute to both local and international debates regarding the present and future of the field.     

The Evolution of Well-Being in Spain (1980–2001): A Regional Analysis

Evaluations of regional welfare conventionally rely on Gross Value Added (GVA) per capita as an indicator of well-being. This paper attempts to re-address the regional welfare issue using alternative indicators to per capita income. With this aim, a database for the Spanish regions (NUTS II) has been constructed for the period 1980–2001 and an augmented version of the United Nations Development Programme (UNDP) Human Development Index (HDI) has been estimated incorporating indicators of health, education and per capita income. The results show that, whereas regional income per capita disparities have remained constant, regional convergence in the Augmented Human Development Index (AHDI) was achieved between 1980 and 2001. None the less, there is no evidence of intra-distributional mobility (leap-frogging) across regions in the AHDI     

Media Exposure and Health in Europe: Mediators and Moderators of Media Systems

This study examined media exposure as an explanatory factor for individual and cross-national differences in self-assessed general health. In studying media exposure, traditional media (television, radio, and newspapers) and contemporary media (internet) were separately considered. Aside from hypotheses about the relation between media exposure and general health, we also tested hypotheses regarding the mediating role of social isolation and mean world syndrome as well as the moderating role of different media systems across countries. Therefore, we used European Social Survey 2010, covering 25 European countries (n = 36,692). The results of our multilevel regression analyses indicated that exposure to television was negatively related to general health, whereas exposure to radio and newspapers were positively related to health. For contemporary media, findings indicated consistent positive relations between internet exposure and health across. Furthermore, limited support was found for the mediating role of social isolation and the mean world syndrome in the link between media exposure and health. Across media systems, findings for the relations between exposure to the various types of media and health proved to be robust.     

Socio-economic status and life satisfaction in Turkey

The relationship between one's objective living conditions and his/her subjective well-being is a problematic one. This paper discusses the results of a survey conducted in Turkey to explore the impacts of socio-economic status on satisfaction with various domains of life, and satisfaction of basic, and social and psychological needs. The results from the univariate, bivariate analyses and the multiple discriminant analysis indicate that socio-economic status is a strong determining factor in satisfaction with life domains and satisfaction of needs.     

A pilot study in the use of the quality of life interview schedule

The purpose of this study was to refine the Quality of Life Interview Schedule (QUOLIS¢) approach to measuring the quality of life of developmentally handicapped adults who are unable to complete a written questionnaire or a verbal interview. Emphasis was placed on the evaluation of intra- and inter-rater agreement. Ten interviews were conducted. Informants were primarily parents and residential counselors. The results indicate that the QUOLIS¢ approach is generally acceptable to informants, the rating scales are sensitive, and the majority of scores have substantial to almost perfect correlations of intra- and inter-rater agreement.     

"Barebacking": intentional condomless anal sex in HIV-risk contexts. Reasons for and against it

Intentional condomless anal sex in HIV-risk contexts ("barebacking") has been heatedly debated in gay circles, the gay media, and, to a lesser degree, the mainstream media. Yet it has received little attention in the scientific literature. In order to better understand the reasons behind this behavior, we conducted a content analysis of messages posted on an Internet message board following Gay.com's decision to close a company-sponsored bareback chat room. Individuals posting messages self-identified in their online profiles as being mostly White/ European gay men residing in the US, with an average age of 35 years. Out of 130 messages, 62 (48%) were pro-barebacking, 55 (42%) were against barebacking, and 13 (10%) referred to other topics. The content analysis of the messages showed that both those in favor of and against barebacking felt well-informed about HIV/AIDS and the risks of HIV transmission. Those in favor considered condomless sex more enjoyable than sex with condoms (both in actual experience and in erotic imagery), felt that condomless sex conferred a sense of freedom, minimized the risks involved in barebacking (assuming that practitioners were already HIV infected and that the risk of superinfection was small), and ultimately believed that barebacking was a personal decision and responsibility. Those against barebacking believed the behavior was dangerous, advocated for condom use and personal and social responsibility, and felt barebackers needed to be sensitized to the burdens of HIV disease. Implications of these results are discussed, pointing out the need for further scientific inquiry in this area.     

The Compensating Income Variation of Social Capital

There is a small but growing literature on the determinants of social capital. Most of these studies use a measure of trust to define social capital empirically. In this paper we use three different measures of social capital: the size of the individual’s social network, the extent of their social safety net and membership of unions or associations. A second contribution to the literature is that we analyze what social capital contributes to our well-being. Based on this, we calculate the compensating income variation of social capital. We find differences in social capital when we differentiate according to individual characteristics such as education, age, place of residence, household composition and health. Household income generally has a statistically significant effect. We find a significant effect of social capital on␣life␣satisfaction. Consequently, the compensating income variation of social capital is substantial. Thanks to Tijl Woortman for his research assistance.
