Exploring Flemish Muslim children’s experiences and negotiation of offline and online group privacy
Full text linkIn privacy research, much attention has been devoted to the online privacy practices of adolescents and college youth. Less is known about the privacy management of children and Muslim children in particular. In this study, we gave a voice to Muslim children in the northern Dutch-speaking region of Belgium, and how they negotiate information about their Muslim culture and identity using focus groups and interviews. The empirical studies clarify how different privacy management strategies are used to manage and hide Islam-related information. Overall, our results illustrate how besides managing boundaries around the self, Muslim children take into account the minority group they belong to as well as the representation of that particular group when sharing information. Building further on Petronio's communication privacy management theory and Cohen's perspective on privacy as critical and playful subjectivity, we argue to move beyond individual-centric conceptualizations to understand privacy of minority groups
A qualitative analysis of the value creation of Urban Living Labs
No full textOver the past decade, Open Innovation (OI) literature has extended its scope beyond strictly economical contexts to the context of societal value creation. This has given rise to the notion of distributed knowledge as a driver for sustainable innovation development. Over the past 15 years, the concept of Urban Living Labs (ULLs) has gained popularity to put social OI into practice. Hence, this concept is often applied in urban environments to support transition processes that try to tackle so-called wicked problems. However, a fuzzy understanding of this ULL concept still exists, due to an unclear understanding of its value creation mechanics. Therefore, this paper aims to both conceptualise and gain a better understanding of how ULLs are instrumentalised and create value. This is studied from the perspective of “ecosystem stakeholders” that participate in ULL projects. These insights are obtained through a case study with a multimethod qualitative research approach. The main data sources are a series of 20 semi-structured key-informant interviews, four focus groups, and participatory observation. The results show that the value creation for the participating stakeholders can be summarised in two main clusters: (1) the ULL as a way to build and strengthen the capacities of participating stakeholders; and (2) the ULL as a way to facilitate purpose driven fulfilment in urban transition processes
The city as an experimental environment : the identification, selection, and activation of distributed knowledge in regional open innovation ecosystems
Full text linkOver the past decade, open innovation (OI) literature has extended its scope beyond strictly economic contexts to the context of societal value creation. This has given rise to the notion of (local) distributed knowledge as a driver for sustainable innovation and has highlighted the importance of multi-stakeholder collaborations in new product development (NPD) processes to develop new ICT systems for complex urban issues. Several studies have discussed sustainable stakeholder ecosystem architectures for such collaborations. However, little is known about stakeholder identification and selection processes for collaborations in the urban environment. By combining action research with a case study design, this paper studies the nature of contextualized interactions between knowledge actors in the ecosystem and the processes of attraction, identification, selection, and activation of stakeholders in an urban living lab (ULL). These insights converge in the development of a ‘stakeholder acupuncture framework’, which structures mechanisms and practices within dynamic collaboration ecosystems and defines key boundary conditions for such open-ended ecosystems
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Comparing Virtual and Real-Life Rapid Prototyping Methods for User Testing Smart City Interfaces: A Case Study
Full text linkIn the development of complex embedded interactive systems, a tension arises between, on the one hand, ever shorter and highly iterative design processes, and, on the other hand, the need for user testing with early prototypes to validate systems from a user-centred design perspective. This study focuses on the integration of Virtual Reality (VR) into prototyping embedded interactive systems, examining its potential to bridge the gap between rapid prototyping and user-centered design validation. Adopting a comparative research approach, we analyze a case study: the development of a cultural smart city experience. It juxtaposes in situ, low-fidelity prototype testing with VR-based testing, evaluating their realism, interactivity, functionality, presence and task difficulty. This mixed-method research design incorporates both qualitative and quantitative methodologies, engaging 27 design students in a comparative study, conducting participatory research and 8 expert interviews. These findings reveal divergent roles in field testing and VR in the new product development process, highlighting VR’s strengths in visualizing procedures and facilitating discussion. This study identifies the limitations of VR in mimicking realistic interactions and incorporating social context yet underscores its superiority over paper prototypes in its realism and interactivity. Where field testing can hold broader contextual insights, the VR prototype gives more concrete and applied insights. The main advantage of VR testing is its visualisation of procedures and its final materialisation according to the participants interviewed. According to the experts interviewed, VR can be used as a useful tool within the development process especially for visualisation and testing user flows of complex interfaces
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
