Internet-mediated Phonetics

Facebook is a medium of social interaction producing its own style. The present study analyses how users from Malaga create this style through phonetic features of the local Spanish variety and how they reflect on the use of these features. Moreover, the use of non-standard variants by users from Malaga is examined and compared to an oral corpus. Results demonstrate that social factors work differently in real and virtual speech. Thus, the electronic medium constrains the phonetics of the local variety employed on Facebook. Facebook communication is seen as a style serving to create social meaning and to express linguistic identity.

Constructing a Community : Myths and Realities of the Open Development Model

The open development model of software production has been characterized as the future model of knowledge production and distributed work. Open development model refers to publicly available source code ensured by an open source license, and the extensive and varied distributed participation of volunteers enabled by the Internet. Contemporary spokesmen of open source communities and academics view open source development as a new form of volunteer work activity characterized by hacker ethic and bazaar governance . The development of the Linux operating system is perhaps the best know example of such an open source project. It started as an effort by a user-developer and grew quickly into a large project with hundreds of user-developer as contributors. However, in hybrids , in which firms participate in open source projects oriented towards end-users, it seems that most users do not write code. The OpenOffice.org project, initiated by Sun Microsystems, in this study represents such a project. In addition, the Finnish public sector ICT decision-making concerning open source use is studied. The purpose is to explore the assumptions, theories and myths related to the open development model by analysing the discursive construction of the OpenOffice.org community: its developers, users and management. The qualitative study aims at shedding light on the dynamics and challenges of community construction and maintenance, and related power relations in hybrid open source, by asking two main research questions: How is the structure and membership constellation of the community, specifically the relation between developers and users linguistically constructed in hybrid open development? What characterizes Internet-mediated virtual communities and how can they be defined? How do they differ from hierarchical forms of knowledge production on one hand and from traditional volunteer communities on the other? The study utilizes sociological, psychological and anthropological concepts of community for understanding the connection between the real and the imaginary in so-called virtual open source communities. Intermediary methodological and analytical concepts are borrowed from discourse and rhetorical theories. A discursive-rhetorical approach is offered as a methodological toolkit for studying texts and writing in Internet communities. The empirical chapters approach the problem of community and its membership from four complementary points of views. The data comprises mailing list discussion, personal interviews, web page writings, email exchanges, field notes and other historical documents. The four viewpoints are: 1) the community as conceived by volunteers 2) the individual contributor s attachment to the project 3) public sector organizations as users of open source 4) the community as articulated by the community manager. I arrive at four conclusions concerning my empirical studies (1-4) and two general conclusions (5-6). 1) Sun Microsystems and OpenOffice.org Groupware volunteers failed in developing necessary and sufficient open code and open dialogue to ensure collaboration thus splitting the Groupware community into volunteers we and the firm them . 2) Instead of separating intrinsic and extrinsic motivations, I find that volunteers unique patterns of motivations are tied to changing objects and personal histories prior and during participation in the OpenOffice.org Lingucomponent project. Rather than seeing volunteers as a unified community, they can be better understood as independent entrepreneurs in search of a collaborative community . The boundaries between work and hobby are blurred and shifting, thus questioning the usefulness of the concept of volunteer . 3) The public sector ICT discourse portrays a dilemma and tension between the freedom to choose, use and develop one s desktop in the spirit of open source on one hand and the striving for better desktop control and maintenance by IT staff and user advocates, on the other. The link between the global OpenOffice.org community and the local end-user practices are weak and mediated by the problematic IT staff-(end)user relationship. 4) Authoring community can be seen as a new hybrid open source community-type of managerial practice. The ambiguous concept of community is a powerful strategic tool for orienting towards multiple real and imaginary audiences as evidenced in the global membership rhetoric. 5) The changing and contradictory discourses of this study show a change in the conceptual system and developer-user relationship of the open development model. This change is characterized as a movement from hacker ethic and bazaar governance to more professionally and strategically regulated community. 6) Community is simultaneously real and imagined, and can be characterized as a runaway community . Discursive-action can be seen as a specific type of online open source engagement. Hierarchies and structures are created through discursive acts. Key words: Open Source Software, open development model, community, motivation, discourse, rhetoric, developer, user, end-user

Ethnicity, Social Capital and the Internet

This article explores web sites developed to express the interests and experiences of young Chinese people in Britain. Drawing on content analysis of site discussions and dialogues with site users, we argue these new communicative practices are best understood through a reworking of the social capital problematic. Firstly by recognising the irreducibility of Internet-mediated connections to the calculative instrumentalism underlying many applications of social capital theory. Secondly, by providing a more differentiated account of social capital. The interactions we explore comprise a specifically “second generation” form of social capital, cutting across the binary of bonding and bridging social capital. Thirdly judgement on the social capital consequences of Internet interactions must await a longer-term assessment of whether British Chinese institutions emerge to engage with the wider polity.

Virtual reality or virtually real : blended teaching and learning in a Master's level research methods class

This paper examines the enabling effect of using blended learning and synchronous internet mediated communication technologies to improve learning and develop a Sense of Community (SOC) in a group of post-graduate students consisting of a mix of on-campus and off-campus students. Both quantitative and qualitative data collected over a number of years supports the assertion that the blended learning environment enhanced both teaching and learning. The development of a SOC was pivotal to the success of the blended approach when working with geographically isolated groups within a single learning environment.

How central are clients in sexual networks created by commercial sex?

Sex workers are traditionally considered important vectors of transmission of sexually transmitted infections (STI). The role of clients is commonly overlooked, partially due to the lack of evidence on clients' position in the sexual network created by commercial sex. Contrasting the diffusion importance of sex workers and their clients in the map of their sexual encounters in two Web-mediated communities, we find that from diffusion perspective, clients are as important as sex workers. Their diffusion importance is closely linked to the geography of the sexual encounters: as a result of different movement patterns, travelling clients shorten network distances between distant network neighborhoods and thus facilitate contagion among them more than sex workers, and find themselves more often in the core of the network by which they could contribute to the persistence of STIs in the community. These findings position clients into the set of the key actors and highlight the role of human mobility in the transmission of STIs in commercial sexual networks.

As comunidades virtuais no Facebook no setor do vinho: estudo de caso

A Internet tem conseguido mudar os limites das interações sociais e económicas, por fornecer uma infraestrutura robusta para comunicação sem constrangimento de distâncias no tempo e no espaço, que pode ser usada em diversas formas para acumulação e arquivo de recursos de conhecimento. Esta revolução da Internet levou a uma difusão sem precedentes de comunidades virtuais em que os consumidores participam e expressam as suas opiniões sobre os produtos e serviços que consomem ou pretendem consumir. O presente trabalho pretende explorar a temática das comunidades virtuais como fator de inovação, tendo como base o estudo de caso de uma comunidade virtual ligada ao setor do vinho, procurando compreender até que ponto as comunidades virtuais podem contribuir para a evolução dos produtos ou mesmo para a criação de novos produtos. O trabalho inicia-se com a revisão da literatura em torno do conhecimento, internet, comunidades virtuais, lead users e o processo de inovação, crowdsourcing e a cocriação no processo de desenvolvimento de novos produtos. Conclui-se que as empresas podem construir estratégias que permitam uma canalização da informação proporcionada pelos consumidores e Lead Users, procurando, por exemplo, utilização de ferramentas de crowdsourcing. Segue-se a aplicação de uma estratégia de investigação qualitativa, o estudo de caso, à página no Facebook Vinhos do Alentejo, em que se analisa uma comunidade de consumidores de vinhos do Alentejo que proporciona ideias de melhoria do produto ou da experiência de consumo. A recolha dos dados dessa página e a análise de conteúdo foram apoiadas pelo NVivo 10. Como principais resultados destacam-se a utilização desta página como ferramenta de marketing, na divulgação dos vinhos, da gastronomia, da região do Alentejo e ainda a obtenção de experiências preferidas de consumo dos vinhos.

Mathematics teacher education and technology

Various applications of electronic technology have contributed to the field of mathematics teacher education, but the array of tools now' available to teacher educators in developed countries can be somewhat daunting. In this chapter, the authors present an overview of some of these tools and the ways that they are being used. In addition, they address issues surrounding the development and applications of digital technology in teacher education programs in a number of countries. In particular, they present recent applications of videotapes, multimedia resources, internet-based communities, and tutorial conferencing facilities in pre-service and in-service education of mathematics teachers. As professionals who have used technology in teacher education, the authors blend their own insights into this review of technological tools and relevant issues.

Squatting at the digital campfire: researching the open source software community

This paper describes an internet-mediated netnography of the open source software (OSS) community. A brief history of OSS is presented, along with a discussion of the defining characteristics of the phenomenon. A theoretical rationale for the method is then offered and several unique features detailed. The evolution of the methodology in practice is described and salient lessons highlighted. In addition to gathering a large volume of rich data as intended, early phases of the implementation of this method produced a number of unanticipated but significant findings. The paper concludes by summarising the key methodological considerations for conducting a phenomenology of a true online community

Fóruns no ambiente Teleduc: reflexões sobre o papel dos mediadores e estratégias de gerenciamento de debates

Online discussion forums have been widely used in internet-mediated courses and blended courses. In these learning contexts, the mediator's (or tutor's) role in supporting successful learning is of considerable importance. Firstly, the present article discusses some studies in which the mediator's role in online learning environments is emphasized. Secondly, we use this discussion to support our qualitative case-study analysis, in which we investigated mediators' debate-management strategies in TelEduc virtual forums. Lastly, we propose a reflective framework about management strategies in forums in virtual learning platforms.

The first time delivery of the first link learning series using Skype and YouTube

Introduction: This case study documented the experiences of informal and service providers who participated in the first time delivery of the First Link Learning Series from May–August 2013 in Newfoundland and Labrador. The aim of this study was to understand how informal caregivers of people with dementia experience this Internet mediated health resource, and how Skype and YouTube can be used as tools for the Alzheimer Society of Newfoundland and Labrador to effectively deliver the First Link Learning Series. Methods: Sources of data included key informant interviews (n=3), pre- study and post-study interviews with informal dementia caregivers (n=2), institutional documentation, field notes, and YouTube analytics. Framework Analysis was used to make meaning of the qualitative data, and descriptive statistics were used to report on quantitative outcomes. Findings: Between 3% and 17% of registered First Link clients attended the learning series sessions, however only two caregivers participated using Skype or YouTube. Framework Analysis revealed three shared themes: access, connection and privacy. Discussion: The themes helped to begin building theory about barriers and facilitators to Internet mediated health resources for informal dementia caregivers. Experiences of service providers using the Internet to support clients served to begin building a case for the appropriateness of these media. A modified version of Dansky et al.’s (2006) theoretical framework for evaluating E-Health research that situates the person/user in the model, helped guide discussion and propose future directions for the study of Internet based health resources for informal dementia caregivers.

Communities, networks, individuals : place, self and everyday life on the internet

In this paper, I review the long-established use of the concept of ‘community’ which attempts both to perceive and analyse the experience of human interaction, mediated by networked computing. Ever since this form of communication commenced, it was clear that it was no ‘bloodless technological ritual’ (Rheingold, 1994), but something much more deeply human and expressive. For many years, the conceptual apparatus of ‘community’ served as the primary means for understanding the limits and potentials of this activity. However, the recent rise of social networking and social media might cast doubt on the legitimacy of this contested term’s continued relevance. Thus, I move from community to self, via the network notation that has come now to dominate our terminologies. I seek to demonstrate that, as the Internet has become interleaved with everyday life to the point where there is no distinction, for many people, between online and offline, we need to think again about how and what community might mean. In doing so, I suggest that the relationship between self and others, mediated or otherwise, is always one of shared ‘place’ but that contemporary practices of social networking differ significantly in how that place is shared and the degree of collective effort required.

Appropriating Bimby on the Internet: Perspectives on technology mediated meals by a virtual brand community

It was Christmas day when an intriguing news piece about a kitchen technology was published in the Wall Street Journal in 2013 (Kowsmann, 2013). Immediately after, the piece went viral in the Portuguese (social) media (TV, blogs, press). It reported an odd 'obsession' of Portuguese consumers with a pricey German-made kitchen appliance - the Bimby (Figure 7.1) - during a difficult period of 'painful budget slashing in return for an international bailout'. The news piece served to unveil the irony: how come ''Western Europe's poorest country' could afford such an expensive technology 'that outsells high-end iPads [...] and is more popular on Facebook than the country's best-known rock band?' The journalistic piece advanced explanations for this technology craze: 'But the Portuguese love gadgets and seem determined, despite hard times, to maintain their tradition of regularly getting together for dinner. In this explanatory attempt, Bimby is portrayed as an intermediary that opens up the possibility for thinking about meal practices in a particular way, in this case, linking nation and meals through ideas around commensality.
