Imagined and occasional co-presence in open adoption: how adoptive parents mediate birth connections.

This chapter explores the ways that adopted children and their birth parents can remain co-present following adoption. It focuses specifically on public adoption of children who have been in the care of child welfare services, and draws on adoptive parents’ accounts of their experiences of adoption openness. The distinctive features of co-presence between children and their birth parents after adoption are: that it is mediated by negotiated contact agreements and through on-going adoptive family practices; and that it is occasional, with its infrequency displaying the status and significance of birth relationships. Physical co-presence can in some cases be achieved through face-to-face contact meetings, however, even when this not possible, birth parents can be present in the hearts and minds of the adoptive family, constituting a form of imagined co-presence. The chapter explores how adopters achieve, delimit and mediate imagined and physical co-presence between their child and birth parent and concludes by considering the emergence of virtual co-presence via online social media.

A integração de media sociais nas organizações de gestão de destinos: proposta de um modelo orientador para a utilização de media sociais nas atividades de comunicação com os turistas

Sendo o turismo um dos setores económicos onde a informação desempenha um papel fundamental, é, também, um dos mais afetados com a chegada da nova realidade que são os media sociais. Atualmente, devido à utilização generalizada de aplicações da Web 2.0 e, sobretudo, devido ao crescimento exponencial da utilização de aplicações de media sociais, verifica-se que esta utilização está a provocar alterações significativas na promoção dos destinos turísticos, com uma estratégia clara destes passarem a utilizar os conteúdos gerados pelos utilizadores na Internet. Perante este novo paradigma, as Organizações de Gestão de Destinos, como organizações dinâmicas cujo objetivo é a promoção dos destinos turísticos, têm que se adaptar de forma a enquadrar esta nova realidade. O presente trabalho pretende, pois, analisar a forma como as Organizações de Gestão de Destinos portuguesas utilizam a Internet, e em particular as aplicações da Web 2.0/media sociais nas suas estratégias de comunicação. Assim, pretende-se fazer uma análise da situação atual em que se encontram as Organizações de Gestão de Destinos Portuguesas, na utilização deste tipo de aplicações para, a partir daí, se desenvolver uma proposta de modelo orientador para a utilização de media sociais nas atividades de comunicação com os turistas, que permita explorar ao máximo este enorme potencial. Como resultado desta investigação, espera-se contribuir para uma melhor compreensão de como as Organizações de Gestão de Destinos Portuguesas devem usar as aplicações de media sociais nas suas estratégias de comunicação por aplicação da proposta de modelo desenvolvida.

Developing a Technoself System to Improve Lifelong Learning Engagement

Lifelong learning exists today in the context of a cultural and societal shift to a knowledge-based, technology-enhanced, and rapidly-changing economy. It has a significant impact on people’s lives and has become of vital importance with the emergence of new technologies that change how people communicate, collect information, and collaborate with others. The emerging technologies, such as social networking, interactive media and game technology, have expanded a new dimension of self – ‘technoself’ driven by socio-technical innovations and taken an important step forward in lifelong learning through the Technology Enhanced Learning (TEL). The TEL encourages learners as producers to embed personalized knowledge and collective experience on individualized learning within professional practice. It becomes more personal and social than traditional lifelong learning, especially about the ‘learning as socially grounded’ aspects. This paper studies the development of technoself system during lifelong learning and introduces technoself enhanced learning as a novel sociological framework of lifelong learning to couple the educational dimension with social dimension in order to enhance learner engagement by shaping personal learning focus and setting. We examine how people construct their own inquiry and learn from others, how people shift and adapt in these technoself-enhanced learning environments, and how learner engagement is improving as the involvement of learners as producers in lifelong learning. We further discuss the barriers and the positive and negative unintended consequences of using technology for lifelong learning.

Did We Fail? (Counter-)Transference in a Qualitative Media Research Interview

Drawing on Joke Hermes’ (2006) account of a troubling interview, this article reproduces and reflects on passages from a qualitative interview with a user of a social networking site that was experienced as uncomfortable by both interviewee and interviewer (myself). The psychoanalytic concept of (counter-)transference is used to analyse the possible processes that led to the emergence of two narratives by the interviewee and interviewer and resulted in an unsuccessful research encounter. It is suggested that the analysis of the interview narratives may contribute to Wanda S. Pillow’s (2003) notion of an ‘uncomfortable reflexivity’. It may further add to methodological discussions of the interview in media research by placing an emphasis on a complex theory of the subject and intersubjective dynamics.

Dynamic power- and failure-aware cloud resources allocation for Sets of independent tasks

Cloud computing is increasingly being adopted in different scenarios, like social networking, business applications, scientific experiments, etc. Relying in virtualization technology, the construction of these computing environments targets improvements in the infrastructure, such as power-efficiency and fulfillment of users’ SLA specifications. The methodology usually applied is packing all the virtual machines on the proper physical servers. However, failure occurrences in these networked computing systems can induce substantial negative impact on system performance, deviating the system from ours initial objectives. In this work, we propose adapted algorithms to dynamically map virtual machines to physical hosts, in order to improve cloud infrastructure power-efficiency, with low impact on users’ required performance. Our decision making algorithms leverage proactive fault-tolerance techniques to deal with systems failures, allied with virtual machine technology to share nodes resources in an accurately and controlled manner. The results indicate that our algorithms perform better targeting power-efficiency and SLA fulfillment, in face of cloud infrastructure failures.

Relações públicas na era digital: a moda em questão

De todas as áreas que sofrerão alterações com o surgimento das Redes Sociais, as Relações Públicas encontram-se na fila da frente desde o seu começo, uma vez que os social media implicam um público e o estabelecimento de um relacionamento com este. Mesmo as dinâmicas presentes nas RP antes da era 2.0, como é o exemplo das relações com os media, interacção com stakeholders ou a gestão de crises, não só estão presentes nas Redes Sociais como são acentuadas e amplificadas por estas. Neste mundo digital, as marcas de moda ligadas ao prêt-à-porter expandem a sua comunicação a outro nível, adaptando-se às novas tecnologias e tirando o máximo partido do potencial que estas têm para lhes oferecer. Apostam em redes sociais como o Facebook e os Blogs da área da moda & beleza de modo a envolver e cativar o seu público-alvo e stakeholders de uma forma muito mais directa, onde estes têm agora uma voz activa e um papel determinante no sucesso da marca. Idealizadas para gerar notoriedade e aumentar a reputação das marcas, como se demonstra ao longo do presente Relatório de Estágio, as Redes Sociais são agora o melhor amigo das marcas e das Relações Públicas.

Printed nonuniform antenna array for WI-FI sectorized communications

Wireless networks have joined to the sports venues, offering to the public a set of facilities, such as the access to email, news, and also to use the social networking, uploading their photos. New challenges have emerged to provide Wi-Fi in this densely populated stadiums, such as increasing capacity and coverage. In this article, an access point antenna array to cover a sector of a stadium is presented. Its structure, designed in a low cost material allows to reduce the total manufacturing costs, an important factor due to the large number of antennas required in these venues. The material characteristic, the broad bandwidth of operation (300 MHz), along with to the low side lobe levels, important to reduce interference between sectors, makes this antenna well-positioned for wireless communications in these particular locals.

Fostering e-participation sustainability through a BPM-driven semantic model

According to a recent Eurobarometer survey (2014), 68% of Europeans tend not to trust national governments. As the increasing alienation of citizens from politics endangers democracy and welfare, governments, practitioners and researchers look for innovative means to engage citizens in policy matters. One of the measures intended to overcome the so-called democratic deficit is the promotion of civic participation. Digital media proliferation offers a set of novel characteristics related to interactivity, ubiquitous connectivity, social networking and inclusiveness that enable new forms of societal-wide collaboration with a potential impact on leveraging participative democracy. Following this trend, e-Participation is an emerging research area that consists in the use of Information and Communication Technologies to mediate and transform the relations among citizens and governments towards increasing citizens’ participation in public decision-making. However, despite the widespread efforts to implement e-Participation through research programs, new technologies and projects, exhaustive studies on the achieved outcomes reveal that it has not yet been successfully incorporated in institutional politics. Given the problems underlying e-Participation implementation, the present research suggested that, rather than project-oriented efforts, the cornerstone for successfully implementing e-Participation in public institutions as a sustainable added-value activity is a systematic organisational planning, embodying the principles of open-governance and open-engagement. It further suggested that BPM, as a management discipline, can act as a catalyst to enable the desired transformations towards value creation throughout the policy-making cycle, including political, organisational and, ultimately, citizen value. Following these findings, the primary objective of this research was to provide an instrumental model to foster e-Participation sustainability across Government and Public Administration towards a participatory, inclusive, collaborative and deliberative democracy. The developed artefact, consisting in an e-Participation Organisational Semantic Model (ePOSM) underpinned by a BPM-steered approach, introduces this vision. This approach to e-Participation was modelled through a semi-formal lightweight ontology stack structured in four sub-ontologies, namely e-Participation Strategy, Organisational Units, Functions and Roles. The ePOSM facilitates e-Participation sustainability by: (1) Promoting a common and cross-functional understanding of the concepts underlying e-Participation implementation and of their articulation that bridges the gap between technical and non-technical users; (2) Providing an organisational model which allows a centralised and consistent roll-out of strategy-driven e-Participation initiatives, supported by operational units dedicated to the execution of transformation projects and participatory processes; (3) Providing a standardised organisational structure, goals, functions and roles related to e-Participation processes that enhances process-level interoperability among government agencies; (4) Providing a representation usable in software development for business processes’ automation, which allows advanced querying using a reasoner or inference engine to retrieve concrete and specific information about the e-Participation processes in place. An evaluation of the achieved outcomes, as well a comparative analysis with existent models, suggested that this innovative approach tackling the organisational planning dimension can constitute a stepping stone to harness e-Participation value.

Facebook como o novo canal de distribuição de notícias

As redes sociais estão a mudar a forma como os leitores acedem a conteúdos noticiosos e interagem com eles, não só recomendando notícias como facilitando conversas. Hoje, o Facebook é parte do quotidiano de um quinto da população mundial. Mas poderá esta rede social ser um canal de distribuição de notícias online? Esta investigação a que nos propomos tem por base o estudo de caso do Correio da Manhã, um dos jornais portugueses com maior circulação em papel e que se tornou líder no digital, em grande parte, graças à sua estratégia nas redes sociais. A análise e a aplicação de conceitos sobre o uso do Facebook, com vista ao aumento das audiências de um site noticioso, permitem tirar conclusões, quantitativas e qualitativas, sobre a problemática em questão. Como podem as publicações jornalísticas tirar melhor partido do Facebook? Deverá o jornalismo digital especializar-se na distribuição de notícias através das redes sociais? Quais as estratégias a aplicar para incrementar as audiências de um website através do Facebook como canal de distribuição? Neste contexto, pretendeu-se fazer uma análise sobre a forma como os meios de comunicação social estão a usar o Facebook para uma abordagem das melhores práticas jornalísticas nesta rede social. É nosso propósito examinar o papel das notícias no Facebook e a forma como os jornalistas se devem comportar, numa tentativa de criar regras para se tirar o melhor proveito do Facebook em função das audiências

An Exploration of Professors’ Use of Twitter in Higher Education

Scant research has explored how professors in Canadian universities use Twitter as a teaching tool or to augment knowledge about their subject disciplines. This case study employed a mixed-method approach to examine how professors in an Ontario university use Twitter. Using a variation of the technology acceptance model, the survey (n = 17) found that professor participants—41.2% of whom use Twitter—perceive Twitter as somewhat useful as a teaching tool, not useful for finding and sharing information, and not useful for personal use. Participants’ gender and number of years teaching are not indicators of Twitter use. Furthermore, the level of support from peers and the university may be reasons why some do not use Twitter or have stopped using Twitter. Face-to-face interviews (n = 3) revealed that Twitter is not used in classrooms or lecture halls, but predominantly as a means of sharing information with students and colleagues. Another deterrent to using Twitter is not knowing who to follow. Findings indicate that some professors at this university embrace Twitter, but not necessarily as an in-class teaching tool. The challenge and the advantage of using Twitter is to discover and follow people who tweet material and to select relevant material to pass along to students and colleagues. Professor participants in the study found a use for the social network as a means to increase student engagement, create virtual information-exchange communities, and enrich their own learning.

When the Beautiful Game Turns Ugly: A Study of Fan Experiences of Perceived Match Fixing in Soccer

Limited academic attention has been given to the nexus between corruption in soccer and its impact on fandom. Consequently, the purpose of this qualitative study was to better understand the lived experiences of highly identified soccer fanatics living through this era of match fixing in the sport. Social networking site Twitter was utilized to recruit participants from three continents – Africa, Europe, and North America – based on submissions to the site in response to a perceived fix from a high-profile March, 2013 match. A total of 12 semi-structured interviews were conducted with highly identified soccer fans in accordance with Funk and James’ (2001) Psychological Continuum Model (PCM). Despite the majority of participants feeling skepticism about the purity of soccer today, half of the participants’ fandom remained unchanged in the face of perceived match fixing. Directions for future research and recommendations are considered and discussed.

Community Detection in Multi-Layer Networks

In the scope of the current thesis we review and analyse networks that are formed by nodes with several attributes. We suppose that different layers of communities are embedded in such networks, besides each of the layers is connected with nodes' attributes. For example, examine one of a variety of online social networks: an user participates in a plurality of different groups/communities – schoolfellows, colleagues, clients, etc. We introduce a detection algorithm for the above-mentioned communities. Normally the result of the detection is the community supplemented just by the most dominant attribute, disregarding others. We propose an algorithm that bypasses dominant communities and detects communities which are formed by other nodes' attributes. We also review formation models of the attributed networks and present a Human Communication Network (HCN) model. We introduce a High School Texting Network (HSTN) and examine our methods for that network.

Le transfert informel des connaissances tacites chez les gestionnaires municipaux en situation de coordination

Ce rapport de recherche porte sur une étude s’intéressant au transfert des connaissances tacites chez les gestionnaires, c’est-à-dire le partage de ces connaissances et leur utilisation informelle, durant une situation de coordination dans un service municipal. La thèse est articulée autour des questions suivantes : Quelles sont les situations de coordination vécues par les gestionnaires municipaux? Quelles sont les sources de connaissances tacites partagées et utilisées? Quelles sont les relations de connaissances mobilisées de façon informelle lors du transfert des connaissances tacites? Quels sont les facteurs encourageant ou inhibant le transfert informel des connaissances tacites? À partir d’un modèle basé sur une approche situationnelle (Taylor, 1989 et 1991), nous avons revu la documentation touchant nos questions de recherche. Nous avons défini notamment la récursivité des connaissances et le réseau de connaissances, de même que présenté le modèle de la conversion des connaissances (Nonaka, 1994) et celui de l’actualisation de soi (St-Arnaud, 1996). Nous avons questionné 22 répondants à l’aide d’instruments de mesure qui combinent les techniques de l’incident critique, de l’entrevue cognitive et réflexive, le questionnement sur les réseaux organisationnels et l’observation participante. Tels des filets, ces instruments ont permis de traquer et d’obtenir des données d’une grande richesse sur les connaissances tacites et les comportements informels durant le transfert de connaissances en situation de coordination. Ces données ont été analysées selon une approche méthodologique essentiellement qualitative combinant l’analyse de contenu, la schématisation heuristique et l’analyse des réseaux sociaux. Nos résultats montrent que la complexité d’une situation de coordination conditionne le choix des mécanismes de coordination. De plus, les sources de connaissances sont, du point de vue individuel, le gestionnaire et ses artefacts, de même que son réseau personnel avec ses propres artefacts. Du point de vue collectif, ces sources sont réifiées dans le réseau de connaissances. Les connaissances clés d’une situation de coordination sont celles sur le réseau organisationnel, le contexte, les expériences en gestion et en situation complexe de coordination, la capacité de communiquer, de négocier, d’innover et celle d’attirer l’attention. Individuellement, les gestionnaires privilégient l’actualisation de soi, l’autoformation et la formation contextualisée et, collectivement, la coprésence dans l’action, le réseautage et l’accompagnement. Cette étude fournit un modèle valide du transfert contextualisé des connaissances qui est un cas de coordination complexe d’activités en gestion des connaissances. Ce transfert est concomitant à d’autres situations de coordination. La nature tacite des connaissances prévaut, de même que le mode informel, les médias personnels et les mécanismes d’ajustement mutuel. Les connaissances tacites sont principalement transférées au début des processus de gestion de projet et continuellement durant la rétroaction et le suivi des résultats. Quant aux connaissances explicites, les gestionnaires les utilisent principalement comme un symbole à la fin des processus de gestion de projet. Parmi les personnes et les groupes de personnes d’une situation de transfert contextualisé des connaissances, 10 % jouent des rôles clés, soit ceux d’experts et d’intermédiaires de personnes et d’artefacts. Les personnes en périphérie possèdent un potentiel de structuration, c’est-à-dire de connexité, pour assurer la continuité du réseau de connaissances organisationnel. Notre étude a élargi le modèle général de la complexité d’une situation (Bystrom, 1999; Choo, 2006; Taylor, 1986 et 1991), la théorie de la coordination (Malone et Crowston, 1994), le modèle de la conversion des connaissances (Nonaka, 1994), celui de l’actualisation de soi (St-Arnaud, 1996) et la théorie des réseaux de connaissances (Monge et Contractor, 2003). Notre modèle réaffirme la concomitance de ces modèles généraux selon une approche constructiviste (Giddens, 1987) où la dualité du structurel et la compétence des acteurs sont confirmées et enrichies.

Les procédés scripturaux des salons de clavardage (en français, en anglais et en espagnol) chez les adolescents et les adultes

L’un des aspects les plus percutants des avancées de la technologie des quinze dernières années a trait à la communication médiée par ordinateur : clavardage, messagerie instantanée, courrier électronique, forums de discussion, blogues, sites de réseautage social, etc. En plus d’avoir eu un impact significatif sur la société contemporaine, ces outils de communication ont largement modifié les pratiques d’écriture. Notre objet d’étude est le clavardage en groupe qui offre la possibilité aux scripteurs de communiquer simultanément entre eux. Cet outil de communication présente deux caractéristiques importantes aux plans discursif et communicationnel. Premièrement, on admet de façon générale que le clavardage est une forme de communication hybride : le code utilisé est l’écrit, mais les échanges de messages entrent dans une structure de dialogue qui rappelle l’oral. Deuxièmement, le caractère spontané du clavardage impose la rapidité, tant pour l’encodage que pour le décodage des messages. Dans le cadre d’une étude comparative réalisée sur les pratiques scripturales des clavardeurs francophones (Tatossian et Dagenais 2008), nous avons établi quatre catégories générales pour rendre compte de toutes les variantes scripturales de notre corpus : procédés abréviatifs, substitutions de graphèmes, neutralisations en finale absolue et procédés expressifs. Nous voulons maintenant tester la solidité de notre typologie pour des langues dont le degré de correspondance phonético-graphique diffère. En vertu de l’hypothèse de la profondeur de l’orthographe (orthographic depth hypothesis [ODH]; Katz et Frost 1992) selon laquelle un système orthographique transparent (comme l’italien, l’espagnol ou le serbo-croate) transpose les phonèmes directement dans l’orthographe, nous vérifierons si nos résultats pour le français peuvent être généralisés à des langues dont l’orthographe est dite « transparente » (l’espagnol) comparativement à des langues dont l’orthographe est dite « opaque » (le français et l’anglais). Pour chacune des langues, nous avons voulu répondre à deux question, soit : 1. De quelle manière peut-on classifier les usages scripturaux attestés ? 2. Ces usages graphiques sont-ils les mêmes chez les adolescents et les adultes aux plans qualitatif et quantitatif ? Les phénomènes scripturaux du clavardage impliquent également l’identité générationnelle. L’adolescence est une période caractérisée par la quête d’identité. L’étude de Sebba (2003) sur l’anglais démontre qu’il existe un rapport entre le « détournement de l’orthographe » et la construction identitaire chez les adolescents (par ex. les graffitis, la CMO). De plus, dans ces espaces communicationnels, nous assistons à la formation de communautés d’usagers fondée sur des intérêts communs (Crystal 2006), comme l’est la communauté des adolescents. Pour la collecte des corpus, nous recourrons à des échanges effectués au moyen du protocole Internet Relay Chat (IRC). Aux fins de notre étude, nous délimitons dans chacune des langues deux sous-corpus sociolinguistiquement distincts : le premier constitué à partir de forums de clavardage destinés aux adolescents, le second à partir de forums pour adultes. Pour chacune des langues, nous avons analysé 4 520 énoncés extraits de divers canaux IRC pour adolescents et pour adultes. Nous dressons d’abord un inventaire quantifié des différents phénomènes scripturaux recensés et procédons ensuite à la comparaison des résultats.
