The use of the Internet now has a specific purpose: to find information. Unfortunately, the amount of data available on the Internet is growing exponentially, creating what can be considered a nearly infinite and ever-evolving network with no discernable structure. This rapid growth has raised the question of how to find the most relevant information. Many different techniques have been introduced to address the information overload, including search engines, Semantic Web, and recommender systems, among others. Recommender systems are computer-based techniques that are used to reduce information overload and recommend products likely to interest a user when given some information about the user's profile. This technique is mainly used in e-Commerce to suggest items that fit a customer's purchasing tendencies. The use of recommender systems for e-Government is a research topic that is intended to improve the interaction among public administrations, citizens, and the private sector through reducing information overload on e-Government services. More specifically, e-Democracy aims to increase citizens' participation in democratic processes through the use of information and communication technologies. In this chapter, an architecture of a recommender system that uses fuzzy clustering methods for e-Elections is introduced. In addition, a comparison with the smartvote system, a Web-based Voting Assistance Application (VAA) used to aid voters in finding the party or candidate that is most in line with their preferences, is presented.

On Strong Citizens: A Sociological View on Cognitions and Contentious Participation

The present thesis is about cognitions of left-wing activists and the role they play to better understand contentious participation. It compares activists of three post-industrial social movement organizations in Switzerland, i.e. Solidarity across Borders defending migrant's rights, the Society of Threatened People promoting collective human rights and Greenpeace protecting the environment. It makes use of an innovative mixed methods design combining survey and interview data. The main theoretical contribution is to conceptualize an analytical tool enabling to grasp the cognitive map of these activists by putting forward the concept of strong citizen, summing up their relation to society and politics. The relation to society consists of an extensive relation to others and an interconnected vision of society. Consequently, their primary concerns include the handing of common goods and the equal treatment of individuals with regard to common goods. The relation to politics incorporates a critical and vigilant citizen. They are critical towards political authorities and they appreciate political action by organized groups of the civil society. The thesis states that only by having such worldviews activists are able to construct an injustice, agency and identity frame for the claims of their organizations. Thus, the present work delivers a parsimonious answer to the question of where an injustice, agency and identity frame comes from. It does so by a systematic analysis of four specific arguments. First, it empirically demonstrates that these activists have - at the aggregate level - specific cognitive resources compared to the general population. Second, it describes the content of this specific cognitive outlook by evaluating the appropriateness of the strong citizen concept. Third, it looks at variations between activist's communities and shows that activists of more challenging protest issues are stronger citizens than activists of more mainstream protests. Finally, cognitions are not the only part of the story if one looks at contentious participation. Other factors, i.e. social networks and biographical availability, matter too. Therefore, I test if cognitions are able to contribute in explaining differences between activists' communities if one controls for other factors. In sum, this thesis is thus a first step to demonstrate why one should be concerned about activists' cognitions. - Cette thèse s'intéresse aux cognitions des activistes de gauche et à leur rôle dans le phénomène de la participation contestataire. Des activistes de trois organisations post- industrielles en Suisse sont comparé, à savoir Solidarité sans Frontières qui défend les droits des migrants, la Société des Peuples menacés qui promeut les droits des collectivités minoritaires et Greenpeace qui oeuvre pour la protection de l'environnement. Cette recherche utilise un « mixed methods design » en combinant de manière innovant des données de sondage et d'entretiens. Ma principale contribution théorique réside dans la conceptualisation d'un outil analytique qui permet de saisir la « carte cognitive » des activistes, à travers le concept de « strong citizen » qui se réfère à la relation spécifique qu'entretiennent certains individus avec la société et la politique. Ces individus sont caractérisés par une vision inclusive et interconnectée de la société, ainsi que par une conception politique du citoyen comme critique et vigilant. Mon argument principal est celui selon lequel seuls les individus possédant ce type particulier de cognitions sont capable de construire un cadre d'injustice, d'« agency » et d'identité. Cette thèse apporte donc quelques éléments de réponse à la question de l'origine de ces cadres cognitifs qui sont cruciales pour la participation. Pour ce faire, quatre aspects spécifiques sont analysés de manière systématique. Premièrement, je démontre empiriquement, au niveau agrégé, que ces activistes possèdent effectivement des ressources cognitives spécifiques - en comparaison avec la population générale. Deuxièmement, j'analyse le contenu de ces cognitions, ce qui me permet notamment d'évaluer la pertinence et l'adéquation du concept de « strong citizen ». Troisièmement, en m'intéressant cette fois aux variations entre communautés d'activistes, je démontre que ceux réunis autour d'enjeux protestataires très revendicatifs sont, d'un point de vue cognitif, plus proches de la figure du « strong citizen » que ceux mobilisés sur des enjeux plus consensuels. Finalement, d'autres facteurs, à savoir les réseaux sociaux et la disponibilité biographique, sont intégrés à l'analyse afin de mesurer le réel pouvoir explicatif des cognitions dans l'explication des différences observées entre communautés d'activistes. A travers ces analyses, cette thèse met en avant l'importance du rôle des cognitions dans l'étude de la participation contestataire.

Citizens' preferences for brand name drugs for treating acute and chronic conditions: a pilot study.

Background: Generic drugs have been advocated to decrease the proportion of healthcare costs devoted to drugs, but are still underused. Objective: To assess citizens' preferences for brand name drugs (BNDs) compared with generic drugs for treating acute and chronic conditions. Methods: A questionnaire with eight hypothetical scenarios describing four acute and four chronic conditions was developed, with willingness to pay (WTP) determined using a payment card system randomized to ascending (AO) or descending order (DO) of prices. The questionnaire was distributed with an explanation sheet, an informed consent form and a pre-stamped envelope over a period of 3 weeks in 19 community pharmacies in Lausanne, Switzerland. The questionnaire was distributed to every third customer who also had health insurance, understood French and was aged =16 years (up to a maximum of ten customers per day and 100 per pharmacy). The main outcome measure was preferences assessed by WTP for BNDs as compared with generics, and impact of participants' characteristics on WTP. Results: Of the 1800 questionnaires, 991 were distributed and 393 returned (pharmacy participation rate?=?55%, subject participation rate?=?40%, overall response rate?=?22%); 51.7% were AO and 48.3% DO. Participants were predominantly women (62.6%) and of median age 62 years (range 16-90). The majority (70%) declared no WTP for BNDs as compared with generics. WTP was higher in people with an acute disease than in those with a chronic disease, did not depend on the type of chronic disease, and was higher in people from countries other than Switzerland. Conclusions: Most citizens visiting pharmacies attribute no added value to BNDs as compared with generics, although some citizen characteristics affected WTP. These results could be of interest to several categories of decision makers within the healthcare system.

Citizen participation and the Lisbon Treaty : A legal perspective

How to "bring the [European] Union closer to its citizens" is a vexed and vital problem of European integration. Article 11 TEU on participatory democracy, recently introduced by the Lisbon Treaty, is meant to be part of the solution. The EU Economic and Social Committee has gone so far as to define this provision "a milestone on the road to a people's Europe that is real and feasible". This appears to be an overly optimistic assessment - partly because art. 11 relies heavily on the involvement of civil society organisations, which political science literature suggests is conceptually and/or practically irrelevant to citizen involvement; partly because it largely formalizes participatory practices that have been in existence for years without cognizable effects on citizen participation; and partly because even its most innovative element - the European citizens' initiative (ECI) - does not bring significant changes to the Union's constitutional arrangements in terms of redistributing decision-making power. In addition to that, secondary legislation places significant hurdles on the submission of ECIs and might prevent or delay their becoming a standard democratic practice. This is not to say that art. 11 TEU has no potential at all. Its insertion in the Treaty might provide impetus to rethink and develop past participatory practices, such as horizontal civil dialogue. Moreover, the effects of "popular input" in the form of ECIs on EU institutional dynamics is as yet unknown - and perhaps not negligible, to judge from the keen interest that the European Parliament and other bodies have demonstrated in "appropriating" it as a political asset. Finally, art. 11 raises the stakes of the Union's democratic challenge and might pressure EU institutions to make full use of its potential. Or, if eventually proved inadequate, art. 11 might constitute a constitutional experiment on the way to meaningful forms of direct democracy at EU level.

Correlates of extracurricular sport participation among Swiss adolescents.

BACKGROUND: Based on a large national survey on the health of adolescents, this paper focuses on the socio-demographic and lifestyle correlates of sport practice among Swiss adolescents. The SMASH2002 database includes 7428 vocational apprentices and high school students between the ages of 16 and 20 who answered a self-administered anonymous questionnaire containing 565 items targeting perceived health, health attitudes and behaviour. Weekly episodes of extracurricular sport activity were measured by a four-category scale, and the sample was dichotomised between active (>or=two episodes of sport/week) and inactive (<two episodes of sport/week) respondents. Thirty percent of female respondents and 40.2% of male respondents reported engaging in sport activity at least two to three times a week; another 9.7% of the female and 19.4% of the male respondents reported participating in least one sport activity each day (p<0.01). The percentage of active respondents was higher among students than among vocational apprentices (p<.01), and the rates of sport activity decreased more sharply over time among the apprentices than among the students (p<0.01). Most active adolescents reported having a better feeling of well-being than their inactive peers [among male students: odds ratio (OR): 3.13; 95% confidence interval (95%CI): 1.28-7.70]. The percentage of active females who reported being on a diet was high, and female apprentices exhibited higher involvement in dieting than their inactive peers (OR: 1.68; 95%CI: 1.32-2.14). Relative to the inactive male respondents, the proportion of active male respondents smoking was lower; however, a lower proportion of the latter group did not report drunkenness, and the percentage of those who reported lifetime cannabis consumption was higher among active than inactive students (females, OR:1.57; 95%CI:1.09-2.25; males, OR:1.80; 95%CI: 20-2.69). CONCLUSION: Organised sport activities should be better tailored to the work schedules of apprentices. Practitioners should be aware of the potential for problematic behaviour in the area of dieting and substance use among a subset of sport-oriented adolescents.

La participation des consommateurs à la construction de l'autorité des normes internationales : vers une économie politique internationale de la traduction

Cette thèse explore les implications politiques de la montée en puissance des normes internationales sur nos sociétés contemporaines et pose la problématique des dynamiques participatives des représentants des consommateurs au sein des formes de pouvoir non étatique à l'aide du cas de l'Organisation internationale de normalisation (ISO). Le renforcement du pouvoir des normes internationales et autres spécifications techniques soulève d'importants enjeux démocratiques qui portent aussi bien sur la représentativité des acteurs qui les élaborent, sur l'articulation des prérogatives publiques et privées dans la gouvernance de la mondialisation, que sur le rôle de l'expertise dans la reconnaissance de ces nouvelles formes de pouvoir. La participation du monde associatif intervient sur ces différents enjeux de manière complexe. Cette recherche s'inscrit à la suite des études en relations internationales/économie politique internationale sur les formes d'autorité non étatique et s'inspire du concept de traduction issu de la sociologie des sciences et techniques pour mettre en lumière le rôle des spécifications techniques dans la construction d'une société de consommation centrée sur la liberté de choix et la façon dont les associations de consommateurs se saisissent des arènes de normalisation pour y faire valoir des préoccupations collectives, leur expertise et leur identité. Cette thèse défend l'idée que les consommateurs participent à la construction de l'autorité des normes internationales par leur rôle dans la traduction qui permet de relier les spécifications techniques au fonctionnement des marchés, au cadre réglementaire de la loi et aux préoccupations sociétales. L'analyse repose sur une observation ethnographique des délibérations d'un comité technique de l'ISO, une recherche-­‐action, la réalisation d'entretiens et la consultation de documents d'archives de l'ISO. -- This thesis explores the political significance of the rise of international standards on contemporary societies and questions the participatory dynamics of consumers' representatives within nonstate forms of power, using the case of the International organization for standardization (ISO). The power granted to international standards and other technical specifications raises important democratic issues regarding the representativity of standard-­‐ writers, the public-­‐private relationships involved in this form of governance or the expertise sustaining the recognition of such new forms of power. The participation of civil society associations affect such issues in complex ways. This research relies on international relations/international political economy approaches of nonstate authority and takes inspiration from the concept of translation developed by science and technology studies to highlight the crucial role played by technical specifications in building a consumer society based on the freedom of choice as well as how consumers' associations take stock of standardization arenas to promote collective issues and claim their expertise and identity. This thesis argues that consumers contribute to the construction of the authority of international standards through their role in the translation that links international standards to the market society, the regulatory state as well as to societal preoccupation. The analysis is based on an ethnographic observation of deliberations within an ISO technical committee, a research-­‐action, interviews as well as on the consultation of ISO archives.

Sorting out measures and definitions of screening participation to improve comparability: The example of colorectal cancer.

Participation is a key indicator of the potential effectiveness of any population-based intervention. Defining, measuring and reporting participation in cancer screening programmes has become more heterogeneous as the number and diversity of interventions have increased, and the purposes of this benchmarking parameter have broadened. This study, centred on colorectal cancer, addresses current issues that affect the increasingly complex task of comparing screening participation across settings. Reports from programmes with a defined target population and active invitation scheme, published between 2005 and 2012, were reviewed. Differences in defining and measuring participation were identified and quantified, and participation indicators were grouped by aims of measure and temporal dimensions. We found that consistent terminology, clear and complete reporting of participation definition and systematic documentation of coverage by invitation were lacking. Further, adherence to definitions proposed in the 2010 European Guidelines for Quality Assurance in Colorectal Cancer Screening was suboptimal. Ineligible individuals represented 1% to 15% of invitations, and variable criteria for ineligibility yielded differences in participation estimates that could obscure the interpretation of colorectal cancer screening participation internationally. Excluding ineligible individuals from the reference population enhances comparability of participation measures. Standardised measures of cumulative participation to compare screening protocols with different intervals and inclusion of time since invitation in definitions are urgently needed to improve international comparability of colorectal cancer screening participation. Recommendations to improve comparability of participation indicators in cancer screening interventions are made.
