Individuals often deem market transactions in sex, human organs and surrogacy, among others, repugnant. Repugnance norms can be explained by appealing to social-status concerns. We study an exchange economy in which agents abhor consumption dominance: one’s social status is compromised if one consumes less of every good than someone else does. Dominance may be forestalled by partitioning goods into submarkets and then invoking the repugnance norms that proscribe trade across these submarkets. Dominance may also be forestalled if individuals strategically ‘overconsume’ (...) some goods, interpreted as emergent status goods. When equilibria are multiple, there is scope for welfare-enhancing policies that coordinate on status goods. (shrink)

Kijkwijzer is the name of the new Dutch rating system in use since early 2001 to provide information about the possible harmful effects of movies, home videos and television programs on young people. The rating system is meant to provide audiovisual productions with both age-based and content-based ratings. It is designed to enable self-regulation by the audio-visual sector. The development of Kijkwijzer, which took place under the auspices of NICAM, the Netherlands Institute for the Classification of Audiovisual Media, is based (...) on consumer research among Dutch parents, as well as theories and research on children and the media. The consumer survey that preceded the development of Kijkwijzer revealed that 70% of Dutch parents indicated that they would use a rating system. The majority of parents liked to receive information on the content of media productions, particularly about violence, frightening content, sexual depictions, discrimination, drug abuse, and coarse language. Parents also wanted age categories. Kijkwijzer distinguishes four age categories: All Ages, 6, 12 and 16. This article gives an overview and account of the various principles underlying Kijkwijzer version 1.1. It also offers suggestions for improvement of future versions of Kijkwijzer. (shrink)

Bacterial lipopolysaccharide (LPS) and its active component, lipid A, have been used either alone or as adjuvant in therapeutic anticancer vaccines. Lipid A induces various transcription factors via intracellular signaling cascades initiated by their receptor CD14-TLR4. These events lead to the synthesis of cytokines, which either have direct cytotoxic effect or stimulate the immune system. Their antitumoral effect has been demonstrated in animal models as well as clinical trials. Studies in animal models showed that their antitumoral effect relies mostly on (...) the generation of an effective immune response. In humans, the antitumoral effect was correlated with an antibody response and cell-mediated cytotoxicity. So far, some encouraging results have been achieved in phase I and II clinical trials with regards to response and stabilization of the disease, but an expansion of the studies and trials is needed to find the best conditions for their clinical application.

Several models of narrative persuasion posit that a reader's phenomenological experience of a narrative plays a mediating role in the persuasive effects of the narrative. Because the narrative reading experience is multi-dimensional, this experiment investigates which dimensions of this experience – referred to here as narrative engagement – mediate between reading a story and the persuasive effects of the story. Narrative engagement was manipulated by giving participants a selection task to carry out while reading or by adding language errors to (...) the story. Results showed that the task decreased the engagement dimension Being in Narrative World and the language errors decreased the dimension Attentional Focus. No corresponding effects on attitudes were found. However, comparisons with a control group showed that reading the story rendered attitudes more consistent with the story. Regression analysis indicated that this effect may be explained by readers' emotions regarding the characters. (shrink)

A large share of the available literature on television and ageing depicts old age as a life stage characterized by losses in which people use television as a substitute for decreased activities. The aim of the present study is to investigate how television viewing is part of both selection and compensation strategies. Based on a qualitative interview study among a diverse sample of older adults, we found three ways in which television viewing is part of selection strategies and three ways (...) in which it is part of compensation strategies. In contrast to the focus on compensation in previous research, we found that selection strategies appear to provide a better characterization of older people’s television viewing than compensation strategies. Moreover, particular television viewing behavior does not automatically signal whether television viewing is part of selection or compensation strategies. (shrink)

This article reports on Flemish college students’ news orientations and their uses of traditional and new media for news within a public service media environment. We used five homogeneous focus groups that covered variation in news media use. The analysis of the focus groups revealed major differences in news behaviors and attitudes between participants who mainly depended on traditional media for news, and those who also went online for news. While a growing body of research reports on young people’s increasing (...) use of online media for news, particularly among those that are most disengaged with traditional news media, our findings indicated that only the most eager news-users were motivated to gather information online. Additionally, we found that traditional media, in particular national quality papers and the Flemish public service newscast, were still the main reference points for public affairs information among our participants.
