The Role of Perceptions of Media Bias in General and Issue-Specific Political Participation

Despite a large body of literature documenting factors influencing general political participation, research has lagged in understanding what motivates participation regarding specific issues. Our research fills this gap by examining the interplay of perceptions of media bias, trust in government, and political efficacy on individuals' levels of general and issue-specific political participation. Using survey data with indicators related to general political participation, our results demonstrate that perceptions of media bias overall are negatively related to general political participation. Moreover, this relationship is an indirect one, mediated by trust in government and political efficacy. Using survey data with indicators of issue-specific political participation in the context of stem cell research, our results show that—contrary to the relationship found for general political participation—perceptions of media bias are directly and positively associated with issue-specific participation. Implications for political participation and media bias theories are discussed.     

Content and timing of feedback in a web-based learning environment: effects on learning as a function of prior knowledge

This study investigated the effectiveness of different types of feedback content (elaborate versus global) and feedback timing (immediate versus delayed) for learning genetics in a web-based learning environment as a function of learners' prior knowledge. It was hypothesized that learning outcomes of students with low prior knowledge would be fostered by immediate elaborate feedback, whereas those of students with more prior knowledge would be enhanced by delayed global feedback. Students' perceptions of the feedback they received were explored. Results showed a significant positive effect of global feedback on learning outcomes for higher prior knowledge learners, although those who received elaborate feedback gave a higher appreciation rating. The findings are discussed in terms of implications for the design and delivery of feedback in web-based learning environments.     

An electroactive microwell array for trapping and lysing single-bacterial cells

Interest in single-cell analysis has increased because it allows to understand cell metabolism and characterize disease states, cellular adaptation to environmental changes, cell cycles, etc. Here, the authors propose a device to electrically trap and lyse single-bacterial cells in an array format for high-throughput single-cell analysis. The applied electric field is highly deformed and concentrated toward the inside of the microwell structures patterned on the planar electrode. This configuration effectively generates dielectrophoretic force to attract a single cell per well. The microwell has a comparable size to the target bacterial cell making it possible to trap single cells by physically excluding additional cells. Inducing highly concentrated electric potential on the cell membrane can also effectively lyse the trapped single-bacterial cells. The feasibility of the authors' approach was demonstrated by trapping and lysing Escherichia coli cells at the single-cell level. The present microwell array can be used as a basic tool for individual bacterial cell analysis.     

Sports and Violence Reflected in the Mirror of Modern Societies: Sport Ambiguities

The theory of Norbert Elias, with regard to the ‘civilising process’, widely taken up and nourished by his epigons such as Eric Dunning, does not fully explain the reasons why sport, far from systematically pacifying, tends equally to reproduce or amplify certain violent tendencies in societal groups, when it does not in itself constitute the germ of the violence in the heart of contemporary societies. In fact, Elias considers the ‘new’ social configuration as a tool used to control violence, forgetting that the institutionalisation of budding practices also bears witness to social and societal transformations, including free time, access to education, growth of cities, the economic development of states, circulation of goods, merchandise and people, the forming of the media and communication cultures, and the dissemination of information and cultural models. The purpose of this study is to show how his singular posture prevents Elias from understanding all the facets of sport as being prey to its own tensions and contradictions, particularly when it is a case of examining the ‘educational’ positions of the activity reflected in the mirror of the socio-historical conditions of the production of culture and the ways in which the practice of sport has been instrumentalised.     

Sport and Civilisation: Violence Mastered. From the Lack of a Definition for Violence to the Illusory Pacifying Role of Modern Sports

Following the seminal works of Norbert Elias, with regard to the ‘civilising process’, modern sports are generally considered by the scientific community as being, on the one hand, a privileged means that has long facilitated and contributed to ‘the control and learning of the self-control of impulses’ and, on the other, as a political device, which has facilitated, by penetrating into the private sphere in a restrained and play-oriented fashion, the state's monopoly of violence. They are also considered to have facilitated the socio-genesis of modern states. But is this link so evident that this ‘new’ social configuration can be considered a new tool at the service of violence control? Acceptance is so strong that one can almost forget the contradictions, at least the questions, which can and should emerge from this proposition. It should in fact face up to criticism on a certain number of concrete points: definition of violence, rejection of the long-term view, sport be strictly considered in the light of the pacification of habits and social control, hooliganism, etc. This introductory article presents a series of reflections which aim to enrich Elias's theory by underlining both its accuracy and its weak points.     

Child sex tourism in the context of the 2014 FIFA Football World Cup: the case of the host city of Recife,Brazil

This study aims to analyse the issue of child sex tourism (CST) and its correlation with sporting mega-events, taking into consideration the implementation of preventive public policy in the host city of Recife (located in the north-east of Brazil), during the 2014 FIFA Football World Cup. Through a qualitative approach based on a three-year longitudinal study – using interviews, observation and photographs – the theme will be analysed by considering the involved social issues, and the implications for excluded sectors of society in the organization of so-called mega-events. A total of 36 interviews were conducted with 22 individuals, who were divided into three groups: project managers, local population and children abused. CST does not occur in a vacuum and cannot be disconnected from more general social, economic and cultural concerns, which are often overlooked in analyses. Although this study is based upon a short-term timescale, the results obtained in the analysed projects have been satisfactory, but over the long term, effective social and educational measures must be prioritized in order to improve the situation for the actors involved. As part of a sporting mega-event, the topic of child sex tourism remains marginal, particularly in countries where social inequality persists.     

Adipose tissue lipolytic inhibition enhances the glucoregulatory properties of exercise in type 2 diabetes patients

Aims: Exercise combined with adipose tissue lipolytic inhibition augments intramuscular lipid and glycogen use in type 2 diabetes patients. The present study investigates the impact of adipose tissue lipolytic inhibition during exercise on subsequent postprandial glycemic control in type 2 diabetes patients.

Methods: Fourteen male type 2 diabetes patients (age 65?±?2 years, HbA_1c 6.7?±?0.1% (50?±?2?mmol/mol)) participated in a double-blind placebo-controlled randomized cross-over study in which subjects performed endurance-type exercise after being administered 250?mg of a nicotinic acid analogue (acipimox; ACP) or a placebo (PLA). A control experiment was included in which no exercise was performed (CON).

Results: Sixty minutes of endurance-type exercise (at 45% W_peak) did not significantly lower circulating plasma glucose and insulin excursions in PLA when compared with CON (P?=?.300). Acipimox administration strongly reduced circulating plasma FFA concentrations during exercise (P?i.e. postprandial) in ACP when compared with either CON (P?=?.041 and P?=?.002, respectively) or PLA (P?=?.009 and P?=?.001, respectively).

Conclusions: Collectively, exercise with adipose tissue lipolytic inhibition reduces postprandial blood glucose and insulin excursions and, as such, further improves glycemic control in male type 2 diabetes patients.     

Quandaries in the economics of dual technologies and spillovers from military to civilian research and development

In this paper we argue that the ‘standard’ view of the relationship between military and civilian technology is too simple and cannot account for the variety of historical experiences. In order to understand this relationship, attention must be paid to two things: that technologies have a lifecycle, in different parts of which different types of learning are important; and that the relationship between military and civilian sectors will change depending on the nature of the technology involved, in particular whether it is a process or a product technology. In addition, the standard view does not pay heed to the fact that there are specific organizational requirements to realize any potential cross-benefits. We describe a framework with which to analyse the various features of the relationship taking into account these considerations.
