Attracted but Unsatisfied: The Effects of Sensational Content on Television Consumption Choices

This article investigates experimentally the effects of sensational content on viewing choices and satisfaction in television consumption. The authors found that the presence of verbal violence in one program causes subjects to watch more of that program. However, subjects do not experience higher satisfaction with the program. In addition, they report lower satisfaction with the overall viewing experience. These findings are robust to the use of different program types for the experimental manipulation. Overall, the results pose a challenge to the use of audience figures as a measure of enjoyment or satisfaction.     

Higher education students in contemporary France

The number of students entering higher education started to increase significantly in the mid-1960s. This sharp growth has gone together with diversification in the social background of those attending, creation of new tracks (mainly in technology) and, more recently, a number of pedagogical innovations. Consequently, higher education students in the 1990s have little in common with those described by Pierre Bourdieu and Jean-Claude Passeron in Les héritiers, published in 1964: they are not just young bourgeois whose university career confirms ex-post the social position of his or her family. The relative democratization of access to higher education has allowed young people from other social classes to continue their studies after the baccalauréat. However, this democratization has also created new problems for higher education institutions. They must make financial, organizational and pedagogical adaptation to mass schooling. Higher education students also confront new problems in adapting to such demands of university work as autonomy and initiative. Students' living conditions have also changed: while remaining economically dependent on their parents, they enjoy, especially in the provinces, considerable freedom in the running of their personal lives.     

NEET: A Phenomenom Yet to Be Explored

Who are the NEET? How much do we know about this? What do institutions and the media know about them? How different definitions could get to shared policies? This paper tries to provide an initial overview of the situation regarding the NEET, through an analysis of the emerging international literature on the subject. Different definitions across nations are analyzed in order to reflect on the cultural differences and economics-work policies, in order to then analyze more in deep the Italian situation. In Italy, the phenomenon is still little known in society and, often, not recognized by the acronym NEET, with the many variables that define it, despite statistics showing a rise in numbers (26 % of the total population for the age group considered).     

How Will We Understand What We Teach? - Primary Student Teachers’ Perceptions of their Development of Knowledge and Attitudes Towards Physics

The research outlined in this paper investigated how student teachers perceived the development of their knowledge and attitudes towards physics through video recorded practical workshops based on experiments and subsequent group discussions. During an 8-week physics course, 40 primary science student teachers worked in groups of 13–14 on practical experiments and problem-solving skills in physics. The student teachers were video recorded in order to follow their activities and discussions during the experiments. In connection with every workshop, the student teachers participated in a seminar conducted by their physics teachers and a primary science teacher; they watched the video recording in order to reflect on their activities and how they communicated their conceptions in their group. After the 8 weeks of coursework a questionnaire including a storyline was used to elicit the student teachers’ perceptions of their development of subject matter knowledge from the beginning to the end of the course. Finally, five participants were interviewed after the course. The results provided insight into how aspects such as self-confidence and the meaningfulness of knowledge for primary teaching were perceived as important factors for the primary science student teachers’ development of subject matter knowledge as well as a positive attitude towards physics.     

Seeking sustainability competence and capability in the ESD and HESD literature: an international philosophical hermeneutic analysis

Education for sustainable development (ESD) and higher education for sustainable development (HESD) are complex, multidisciplinary fields of enquiry, drawing on concepts and terms from different disciplines and languages. Although the fields are advancing in their acceptability within educational systems worldwide, they are currently struggling to achieve sought-after graduate and societal outcomes such as environmentally-responsible or sustainability-focussed-citizenship. The research described in this article explores the possibility that miscommunication or misunderstanding of basic concepts within these fields is contributing to slow progress towards their objectives. We used a philosophical hermeneutic analysis to explore how the terms ‘competence’ and ‘capability’ are used within selected ESD/HESD papers. We identify substantial internal contradictions and inconsistencies with respect to differences between learners’ abilities and their willingness to perform these abilities, and to the educational context in which these outcomes are sought. We emphasise the importance of linking educational objectives with pedagogical approaches to teaching and assessment.     

Cultural goods, cultivation of taste, satisfaction and increasing marginal utility during vacations

This paper analyzes the link between cultivation of taste and tourist satisfaction during vacations. A simple model shows that, when cultural capital accumulation matters, customers are ready to sacrifice some of their current utility in order to get higher returns in future, and therefore, the relation between satisfaction and the demand for cultural goods may be convex. On the contrary, when cultivation of taste comes from learning by consuming behavior, the relation is concave. An analysis based on 1,749 interviews in Aosta Valley in Summer 2008 provides some evidence in favor of the cultural capital accumulation hypothesis.     

Selective cell capture and analysis using shallow antibody-coated microchannels

Demand for analysis of rare cells such as circulating tumor cells in blood at the single molecule level has recently grown. For this purpose, several cell separation methods based on antibody-coated micropillars have been developed (e.g., Nagrath et al., Nature 450, 1235–1239 (2007)). However, it is difficult to ensure capture of targeted cells by these methods because capture depends on the probability of cell-micropillar collisions. We developed a new structure that actively exploits cellular flexibility for more efficient capture of a small number of cells in a target area. The depth of the sandwiching channel was slightly smaller than the diameter of the cells to ensure contact with the channel wall. For cell selection, we used anti-epithelial cell adhesion molecule antibodies, which specifically bind epithelial cells. First, we demonstrated cell capture with human promyelocytic leukemia (HL-60) cells, which are relatively homogeneous in size; in situ single molecule analysis was verified by our rolling circle amplification (RCA) method. Then, we used breast cancer cells (SK-BR-3) in blood, and demonstrated selective capture and cancer marker (HER2) detection by RCA. Cell capture by antibody-coated microchannels was greater than with negative control cells (RPMI-1788 lymphocytes) and non-coated microchannels. This system can be used to analyze small numbers of target cells in large quantities of mixed samples.     

New product introduction and product tenure: What effects on firm growth?

This study contributes to the recent empirical literature on the innovation-firm performance relationship by investigating the effect of product introduction on firm growth in a sample of Italian firms from 2000 to 2006. We adopted a novel approach that exploits the interpretative content of the tenure of the last product introduced (i.e., the number of years since its first introduction) as an additional variable into the explanatory scheme of firm sales growth rate. This variable aims to capture peculiar characteristics of new goods, such as their novelty and complexity. The estimated results confirmed the relevance of this model specification and helps in understanding the reason why previous studies have failed to find a statistically robust relationship between product innovation and growth. Moreover, we found the following: first, the release of a new product enhances growth opportunity among multiproduct firms; second, product development promotes the growth of firms belonging to sectors with stronger commitment to research and development; and third, new product development enhances firm growth substantially in those sectors that absorb externally originated patents.
