Participatory Online Platforms and the Construction of Citizen’s Autonomy in Health Issues

The goal of the present study is mapping the nature of possible contributions of participatory online platforms in citizen actions that may contribute in the fight against cancer and its associated consequences. The research is based on the analysis of online solidarity networks, namely the ones residing on Facebook and the blogosphere, that citizens have been gradually resorting to. The research is also based on the development of newer and more efficient solutions that provide the individual (directly or indirectly affected by issues of oncology) with the means to overcome feelings of impotence and fatality. In this chapter, the authors summarize the processes of usage of these decentralized, freer participatory platforms by citizens and institutions, while attempting to unravel existing hype and stigma; the authors also provide a first survey of the importance and the role of institutions in this kind of endeavor; lastly, they present a prototype, developed in the context of the present study that is specifically dedicated to addressing oncology through social media.

The Role of Online Platforms for Media Markets – Two‐Dimensional Spatial Competition in a Two‐Sided Market

We analyze the market for online and offline media in a model of two-dimensional spatial competition where media outlets sell content and advertising space. Consumer preferences are distributed along the style and type of news coverage where the distance costs may vary across dimensions. For integrated provision of online and offline platforms we show that entering the online market reduces average profits and may even constitute a prisoner's dilemma. Specialized provision may yield polarization in the style and type dimensions. This is in contrast to the maximum–minimum differentiation result previously established in the literature on multidimensional horizontal competition. We show that maximal differentiation in both dimensions occurs due to the discrete nature of the type dimension and asymmetric advertising markets.

Illusions of a ‘Bond’: Tagging cultural products across online platforms

La plupart des études sur l'étiquetage social porte sur une plateforme ou un type de plateforme précis, ce qui limite la portée de leurs résultats. Cette étude explore et compare les pratiques d'étiquetage social de quatre plateformes--Goodreads, un catalogue de bibliothèque publique, Last.fm et WordPress--au moyen d'une étude de cas multiples et emboîtés. Le contenu généré par les utilisateurs, principalement les étiquettes ou "tags", lié au livre Casino royale de Ian Fleming ou à ses produits dérivés ou associés (p. ex. : chanson thème, film, billet de blogue) a été analysé avec une approche qualitative et inductive. L'analyse révèle que le contenu généré par les utilisateurs des quatre plateformes mettait l'emphase sur les événements historiques associés au livre tout en fournissant de nombreux points d'accès plus subjectifs : recommandation, ton, ambiance, opinion, expérience de lecture, d'écoute ou de visionnement. On remarque par ailleurs des différences entre les étiquettes associées au livre et à ses produits dérivés : alors que le contenu généré par les utilisateurs en lien avec le produit d'origine dans les catalogues de bibliothèques et dans Goodreads portait essentiellement sur le livre, les étiquettes attribuées par les utilisateurs aux produits dérivés dans Last.fm (la chanson thème du film) et WordPress (des billets de blogues sur le livre ou le film) renvoyaient souvent à d'autres produits culturels, incluant des livres, de la musique et des films.

Crowdinvesting consiste na captação de recursos financeiros por empreendedores, por meio de uma plataforma online na internet, em que os investidores recebem em troca de seus aportes financeiros uma participação na empresa nascente investida. Trata-se de uma modalidade de financiamento peculiar, uma vez que usualmente realiza a oferta pública de valores mobiliários. O objetivo deste trabalho é identificar elementos para se pensar na qualificação jurídica da plataforma online de crowdinvesting, a partir da descrição de suas atividades realizadas no âmbito da oferta pública de valores mobiliários. Para tanto, foi escolhida a plataforma online da Broota Brasil como objeto único de análise, pois é a empresa pioneira na atividade. Identificar os elementos que propiciam uma reflexão acerca da qualificação jurídica que a plataforma online de crowdinvesting é importante, pois permite a (i) reflexão acerca do seu possível tratamento jurídico; e (ii) verificar se há segurança jurídica nas atividades cursadas no âmbito da plataforma online. Para nortear o presente trabalho, foram eleitas duas hipóteses de pesquisa, considerando que a plataforma online consiste em um ambiente virtual que disponibiliza espaço para a realização de ofertas públicas de valores mobiliários, sendo reputada como (i) mercado de balcão organizado; ou (ii) mercado de balcão não organizado. Assim, é realizada a descrição das atividades da plataforma online da Broota Brasil no âmbito da realização de oferta pública de valores mobiliários. Após, com base na legislação e doutrina específica, foi efetuada a descrição das características que conceituam juridicamente as referidas hipóteses.

The decentralized social networking systems towards mobilizing actions of citizenship and solidarity against cancer

The goal of the present study is mapping the nature of possible contributions of participatory online platforms in citizen actions that may contribute in the fight against cancer and its associated consequences. These platforms are usually associated with entertainment: in that sense, we intent to test their validity in other domains such as health, as well as contribute to an expanded perception of their potential by their users. The research is based on the analysis of online solidarity networks, namely the ones residing on Facebook, Orkut and the blogosphere, that citizens have been gradually resorting to. The research is also based on the development of newer and more efficient solutions that provide the individual (directly or indirectly affected by issues of oncology) with the means to overcome feelings of impotence and fatality. In this article, we aim at summarizing the processes of usage of these decentralized, freer participatory platforms by citizens and institutions, while attempting to unravel existing hype and stigma; we also provide a first survey of the importance and the role of institutions in this kind of endeavor; lastly, we present a prototype, developed in the context of the present study, that is specifically dedicated to addressing oncology through social media. This prototype is already available online at www.talkingaboutcancer.org, however, still under development and testing. The main objective of this platform is to allow every citizen to freely build their network of contacts and information, according to their own individual and/ or collective needs and desires.

Die Krankheit Depression kann jeden treffen [In Process Citation].

The survey "Datenerhebung zur Depression in der Allgemeinbevölkerung" was conducted from fall 2010 to spring 2011 on several online platforms. The results show that there is a considerable timespan between the appearance of initial symptoms of depression and the first diagnosis of a patient. Intervention at early stages of the disease can reduce a potentially long time of suffering and can lead to the successful treatment of depression. General practitioners play an important role as the link between patient and psychiatrist.

Drivers and barriers of mobile travel and tourism service adoption : a study of individual perceptions and business model development in a travel and tourism context

The Travel and Tourism field is undergoing changes due to the rapid development of information technology and digital services. Online travel has profoundly changed the way travel and tourism organizations interact with their customers. Mobile technology such as mobile services for pocket devices (e.g. mobile phones) has the potential to take this development even further. Nevertheless, many issues have been highlighted since the early days of mobile services development (e.g. the lack of relevance, ease of use of many services). However, the wide adoption of smartphones and the mobile Internet in many countries as well as the formation of so-called ecosystems between vendors of mobile technology indicate that many of these issues have been overcome. Also when looking at the numbers of downloaded applications related to travel in application stores like Google Play, it seems obvious that mobile travel and tourism services are adopted and used by many individuals. However, as business is expected to start booming in the mobile era, many issues have a tendency to be overlooked. Travelers are generally on the go and thus services that work effectively in mobile settings (e.g. during a trip) are essential. Hence, the individuals’ perceived drivers and barriers to use mobile travel and tourism services in on-site or during trip settings seem particularly valuable to understand; thus this is one primary aim of the thesis. We are, however, also interested in understanding different types of mobile travel service users. Individuals may indeed be very different in their propensity to adopt and use technology based innovations (services). Research is also switching more from investigating issues of mobile service development to understanding individuals’ usage patterns of mobile services. But designing new mobile services may be a complex matter from a service provider perspective. Hence, our secondary aim is to provide insights into drivers and barriers of mobile travel and tourism service development from a holistic business model perspective. To accomplish the research objectives seven different studies have been conducted over a time period from 2002 – 2013. The studies are founded on and contribute to theories within diffusion of innovations, technology acceptance, value creation, user experience and business model development. Several different research methods are utilized: surveys, field and laboratory experiments and action research. The findings suggest that a successful mobile travel and tourism service is a service which supports one or several mobile motives (needs) of individuals such as spontaneous needs, time-critical arrangements, efficiency ambitions, mobility related needs (location features) and entertainment needs. The service could be customized to support travelers’ style of traveling (e.g. organized travel or independent travel) and should be easy to use, especially easy to take into use (access, install and learn) during a trip, without causing security concerns and/or financial risks for the user. In fact, the findings suggest that the most prominent barrier to the use of mobile travel and tourism services during a trip is an individual’s perceived financial cost (entry costs and usage costs). It should, however, be noted that regulations are put in place in the EU regarding data roaming prices between European countries and national telecom operators are starting to see ‘international data subscriptions’ as a sales advantage (e.g. Finnish Sonera provides a data subscription in the Baltic and Nordic region at the same price as in Finland), which will enhance the adoption of mobile travel and tourism services also in international contexts. In order to speed up the adoption rate travel service providers could consider e.g. more local initiatives of free Wi-Fi networks, development of services that can be used, at least to some extent, in an offline mode (do not require costly network access during a trip) and cooperation with telecom operators (e.g. lower usage costs for travelers who use specific mobile services or travel with specific vendors). Furthermore, based on a developed framework for user experience of mobile trip arrangements, the results show that a well-designed mobile site and/or native application, which preferably supports integration with other mobile services, is a must for true mobile presence. In fact, travel service providers who want to build a relationship with their customers need to consider a downloadable native application, but in order to be found through the mobile channel and make contact with potential new customers, a mobile website should be available. Moreover, we have made a first attempt with cluster analysis to identify user categories of mobile services in a travel and tourism context. The following four categories were identified: info-seekers, checkers, bookers and all-rounders. For example “all-rounders”, represented primarily by individuals who use their pocket device for almost any of the investigated mobile travel services, constituted primarily of 23 to 50 year old males with high travel frequency and great online experience. The results also indicate that travel service providers will increasingly become multi-channel providers. To manage multiple online channels, closely integrated and hybrid online platforms for different devices, supporting all steps in a traveler process should be considered. It could be useful for travel service providers to focus more on developing browser-based mobile services (HTML5-solutions) than native applications that work only with specific operating systems and for specific devices. Based on an action research study and utilizing a holistic business model framework called STOF we found that HTML5 as an emerging platform, at least for now, has some limitations regarding the development of the user experience and monetizing the application. In fact, a native application store (e.g. Google Play) may be a key mediator in the adoption of mobile travel and tourism services both from a traveler and a service provider perspective. Moreover, it must be remembered that many device and mobile operating system developers want service providers to specifically create services for their platforms and see native applications as a strategic advantage to sell more devices of a certain kind. The mobile telecom industry has moved into a battle of ecosystems where device makers, developers of operating systems and service developers are to some extent forced to choose their development platforms.

Development of internet-based value added services in housing estate business in Russia

Value added services are becoming increasingly popular as they increase the perceived value of the core product and can be a strong method of attracting customers and motivating them to make a choice. The purpose of this research is to develop internet-based value added services for housing estate business in Russia. The research is a case study of Russian housing estate market utilising a triangulation of methods for better results. For the qualitative data analysis, 7 interviews with heads of regional departments of construction companies from different regions of Russia were conducted. For the quantitative data analysis, a survey of 128 inhabitants of Saint-Petersburg housing estates was held. Factor analysis and descriptive statistics including cross-tabulations and chi-square tests for significance were used to analyse the results. In this study, a list 19 value added services that can be provided through online platforms in housing estate market was developed. These services fall into three big groups: social networking services, compulsory and additional services. Additionally, the question of monetisation of online platforms in housing estate market was discussed and three business models were suggested.

Le capital virtuel : entre compétition, survie et réputation

Les avancées technologiques liées à l’internet ont permis une démocratisation des outils de communication et une transformation des relations interpersonnelles. L’impact de ces changements s’est ressenti autant dans la sphère légitime que dans les marchés criminels. Ces derniers ont migré, au cours des dernières années, vers des plateformes en ligne qui leur permettent de mieux gérer les risques associés avec leurs activités illégales. Cette thèse s’intéresse à l’impact de l’internet sur la criminalité et sur l’adaptation des criminels à cet environnement virtuel. Ces derniers forment maintenant des communautés en ligne et gardent le contact entre eux à l’aide de salles de clavardage et de forums de discussions. Nous nous intéresserons dans cette thèse à trois formes particulières de crime soit la fraude de propriété intellectuelle (la scène des warez), le piratage d’ordinateurs (les botnets) ainsi que la fraude de données personnelles et financières (le carding). Chacune de ces formes de crime sera analysée à l’aide d’un article publié ou présentement en évaluation. L’article sur la scène des warez décrit l'organisation sociale ainsi que la distribution de la reconnaissance dans la communauté des pirates informatiques. Les systèmes de délinquance (Sutherland, 1947) et l’individualisme réseauté (Boase & Wellman, 2006) sont utilisés pour théoriser l'organisation sociale et la distribution de la reconnaissance dans la scène warez. L’article sur les botnets tente de comprendre la distribution de la réputation dans une communauté de criminels. En utilisant les données d’un forum de discussion où des botmasters louent et achètent des biens et services illégaux, cette recherche modélise les facteurs qui permettent d’augmenter le niveau de réputation de certains acteurs. Finalement l’article sur le carding mesure le lien entre la réputation telle que développée par Glückler & Armbrüster (2003) et la performance criminelle. Notre thèse démontre que l’internet a eu un effet transformateur sur la criminalité à six niveaux : 1) l’augmentation de la facilité à trouver des co-criminels; 2) l’augmentation de la compétition entre les criminels; 3) l’augmentation du nombre de victimes; 4) la diminution des risques d’arrestation; 5) l’augmentation du taux de réussite des criminels et; 6) les changements dans l’équilibre entre criminels, victimes et protecteurs. Elle nous permet également de démontrer l’importance de la réputation, le capital virtuel, dans les marchés criminels en ligne.
