Reviving dormant ties in an online social network experiment

Social network users connect and interact with one another to fulfil different kinds of social and information needs. When interaction ceases between two users, we say that their tie becomes dormant. While there are different underlying rea-sons of dormant ties, it is important to find means to revive such ties so as to maintain vibrancy in the relationships. In this work, we thus focus on designing an online experiment to evaluate the effectiveness of personalized social messages to revive dormant ties. The experiment carefully selects users with dormant ties so that each user does not get mixed treat-ments and be affected by the responses of other users un-dergoing treatment. Our results show that personalized mes-sage content plays an important part in reviving dormant ties. Specifically, we find the message containing friend’s recent activity information is more effective than that containing inter-friend activity information. We observe that the quality of engagement of at least 50 % of the revived ties can effec-tively be restored to the level before the ties become dormant. We also observe that it is easier to revive dormant ties that involve users from the same country but not users with the same and different gender

Exploring Users’ Interactive Behaviors in Online Group: A Case Study of QQ Group “TuanRenTang”

The users’ interactive behaviors of the online group chat and an accurate identification of users’ interaction, which can provide method support for mining user interests and the crowd labeling, was analyzed in this paper. By using social network analysis method, the study took QQ Group “TuanRenTang” as an example to analyze users’ interactive behaviors, discover users’ interaction relationships, construct interaction networks, and explore the interaction types and community detection. The findings suggested that both explicit and implicit interaction exist in the same topic discussion. Users could be classified into four categories: active interaction, general interaction, passive interaction and lurking interaction based on different user activity. Besides, twenty “experts” and eight communities on the basis of interaction networks had been found out from the sample data of “TuanRenTang” chat records

Design Challenges for Reconnecting in Later Life: A Qualitative Study

Friendships and social interactions are renown contributors to wellbeing. As such, keeping a healthy amount of relationships becomes very important as people age and the size of their social network tends to decrease. In this paper, we take a step back and explore reconnection —find out about or re-contact old friends, an emerging topic due to the increased use of computer-mediated technology by older adults to maintain friendships and form new ones. We report on our findings from semi-structured interviews with 28 individuals from Costa Rica and Poland. The interviews aimed to explore whether there is a wish to reconnect, and the challenges encountered by older adults to reconnect. We contribute with design considerations for tools allowing older adults to reconnect, discussing opportunities for technologyEU Horizon2020 research and innovation programme under the MarieSkłodowska-Curie grant agreement No 690962.UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias de la Salud::Instituto de Investigaciones en Salud (INISA

WHEN THE PAST COMES KNOCKING: AN ALTER-CENTRIC PERSPECTIVE ON NETWORK MOBILIZATION IN PROSOCIAL OCCUPATIONS

Networks are vital to our ability to access resources. However, scholars have often overlooked just how social networks are mobilized. Underexplored in the literature is how individuals think and feel about mobilizing networks with little attention directed towards the person (alter) being reached out to. In this dissertation, I use a basic, interpretive design to better understand how people think and feel about receiving requests for task-related help, paying particular attention to when those requests originate from people from one’s past. To do so, I conducted interviews with 40 animal rescuers given their passion for helping, but their inability to assist everyone, so they must be selective about which ties to mobilize. My findings show that simply possessing a tie does not always translate into successful mobilization, alters think and feel differently about help-seekers from their past as compared to people they currently interact with, and that people from one’s past may be useful reservoirs of value, but present unique challenges that must be overcome before benefiting from these connections. This work contributes to the literature by better incorporating alters into the mobilization process and helps shift the focus away from only mobilizing current connections and towards mobilizing people from the past

IT-Enabled Social Innovation in China’s Taobao Villages: The Role of Netrepreneurs

We present a model of IT-enabled social innovation. Our model draws on the theoretical lens of social shaping of technology and the role of villagers-turned-netrepreneurs, as reference actors in the context of rural e-commerce development. The model is built on stage-wise observations of intermediary roles that villagers play and how these roles enhance or decrease in importance in the biography of rural to e-commerce villages’ transformations across China in recent years. In this research-in-progress paper, we present a case study of Daji, China’s first “Taobao performance costumes town”, located in rural Shandong province. Our preliminary model prescribes three mechanisms− advancing, authenticating and attaching−that are enacted by reference actors in the process of negotiating rural e-commerce development and resurrecting heritage in their communities. Our model builds on conjectural discussion in recent IS research on the expanding role of the users in influencing the development of IT-enabled social innovation

What Is Dead May Never Die: Institutional Regeneration through Logic Reemergence in Dutch Beer Brewing

Through an in-depth, historically embedded study of the craft revolution in Dutch beer brewing that began in the 1970s, we illuminate how organizational fields may experience regenerative change through the reemergence of traditional arrangements. The remarkable resurgence of craft in this context, following the rapid industrialization of the twentieth century that left only industrially produced pilsner in its wake, serves as the basis of our process theory of regenerative institutional change through logic reemergence. The results of our qualitative analysis show that institutional logics that appear dead or decomposed may never truly die, as they leave remnants behind that field actors can rediscover, repurpose, and reuse at later stages. We show how, in the Netherlands, networks of individuals that had access to the remnants of craft brewing were regenerated, in part fueled by increasing exposure to British, Belgian, and German craft brewing, and how these networks ultimately succeeded in reviving traditional prescriptions for beer and brewing, as well as restoring previously abandoned brewery forms and technologies and beer styles. These activities led not only to a sudden proliferation of alternatives to the dominant industrial pilsner but also to fundamental changes in the meaning and organization of beer brewing, as they were associated with the reinvigoration of institutional orders that preceded those of the corporation and the market. Yet we also observe how, on the ground, remnants of traditional craft often needed to be blended with contemporaneous elements from modern industrialism, as well as foreign representations of craft, to facilitate reemergence. We thus argue that regenerative institutional change likely resembles a dualistic process of restoration and transformation

Beyond Global Food Supply Chains

This open access book takes the upheaval of the global COVID-19 pandemic as a springboard from which to interrogate a larger set of structural, environmental and political fault lines running through the global food system. In a context in which disruptions to the production, distribution, and consumption of food are figured as exceptions to the smooth, just-in-time efficiencies of global supply chains, these essays reveal the global food system as one that is inherently disruptive of human lives and flourishing, and of relationships between people, places, and environments. The pandemic thus represents a particular, acute moment of disruption, offering a lens on a deeper, longer set of systemic processes, and shining new light on transformational possibilities
