Enhancing Online Community Activity: Development and validation of the CA framework

Factors contributing to development of active communities are identified and combined into the Community Activity framework, which is useful in setting up new, or revitalizing inactive, communities. Found factors include: notifying members of new messages by e-mail, having a news section, and ability to add pictures to member profiles. During application of the framework to an inactive community, changes have been made to privacy options, polls, activity notifications, and other areas. Significant positive effects have been found in the number of visits, volume of posted messages, and number of topics. Interest of community members in both user profiles and the message board increased significantly. We conclude that the Community Activity framework is able to contribute in developing active online communities.     

The Story of Collective Action: The Emergence of Ideological Leaders,Collective Action Network Leaders,and Cross-Sector Network Partners in Civil Society

Collective action and community ecology theories frame this study of longitudinal interorganizational networks in Croatia during the country's political transition. As time progresses toward political stability, grass-roots organizing activities shift through participation in new networks. Although engaged cross-sector communication was important in early stages of the transformation, homophilous partnering emerged as the system stabilized. System stability left room for organizations to exit the collective action network but with costs associated with centralized organizing. Over time, organizations embodied roles as ideological leaders, collective action network leaders, and within-sector network partners. We offer a unique contribution to community ecology and collective action theories with a communication-centered framework that emphasizes the nature of communication in interorganizational networks over a 4-year period.     

How heterogeneous community engage newcomers? The effect of community diversity on newcomers’ perception of inclusion: An empirical study in social media service

Online communities that provide social media services need to engage newcomers so as to not lose them to competitors. This study examines the role of community diversity (in terms of perceived visible dissimilarity, perceived informational dissimilarity and perceived value dissimilarity) in influencing perceived inclusion of newcomers in the online community and the influence of such perception on newcomers’ engagement intention. The theoretical background on perceived inclusion is obtained from the optimal distinctiveness theory, which comprises of two dimensions, namely, social identification and perceived uniqueness. The results support the multiple roles of community diversity on a newcomer’s perceived inclusion. The findings of this study contribute to a better understanding of the effect of community diversity on newcomers’ engagement behavior, and provide recommendations on designing a personalized community diversity environment.     

Teargas,taboo and transformation: A neo-institutional study of community resistance and the struggle to legitimize subway projects in Amsterdam 1960–2018

The last decades have witnessed an increasing prevalence of community resistance against large-scale infrastructure projects that pose serious threats to their environment, calling for further empirical scrutiny. Hence, this paper applies a neo-institutional lens to investigate how project actors who plan and implement large-scale infrastructure projects respond to community resistance in their attempt to legitimize and embed these projects in their environment. To do so, we draw from a longitudinal study of two subway projects in Amsterdam; the East line (1965–1980) and the North-South line (1995-2018). While considered crucial for urban development, both projects encountered severe community resistance by locals protecting the historic city. This resistance, in turn, prompted ‘institutional work’ by project actors to socially (re)construct the projects in pursuit of legitimacy from the Amsterdam community. The twofold contribution of the paper to the field of project studies is (1) the application of a neo-institutional lens showcasing the dynamic interrelation between projects and their environment, processes of institutional transformation, and practices of institutional work; and (2) the longitudinal empirical account exhibiting the contextual dialectic of resistance and accommodation with an emphasis on shifting approaches of institutionalization, the constant struggle to acquire legitimacy, and the local embeddedness of projects.

A functional test platform for the Community Land Model

The realistic representation of key biogeophysical and biogeochemical functions is the fundamental of process-based ecosystem models. A functional test platform is designed to create direct linkages between site measurements and the process-based ecosystem model within the Community Earth System Models (CESM). The platform consists of three major parts: 1) interactive user interfaces, 2) functional test models and 3) observational datasets. It provides much needed integration interfaces for both field experimentalists and ecosystem modelers to improve the model's representation of ecosystem processes within the CESM framework without large software overhead.     

国际制度与国家认同互动关系解析——以欧美安全共同体的建构为例

在国际社会中认同与制度化构成一个互动的关系。从认同的角度来看，正向的国家间认同为制度化的发展打下良好基础；从制度的角度来看，国际制度为国家认同的塑造提供平台，高级制度化往往伴随着一个国家内化规范及认同建构的过程。二战后的欧美安全关系的发展就是一个认同与制度化良好互动的典型例证。双方在良好认同的基础上开始制度化进程，而在国际制度基础上的国家间交往，则进一步加深二者对彼此的认知程度，推动欧美关系朝积极的方向发展，最终建立一个稳定有效的欧美安全共同体。     

Social media use,community participation and psychological well-being among individuals with serious mental illnesses

BackgroundLittle research exists on social media (e.g., Facebook, Twitter, etc.) use among individuals with serious mental illnesses (SMI). One particular question of interest is the extent to which online social media use is associated with these individuals' community participation, civic engagement and psychosocial outcomes.MethodsTwo-hundred and thirty-two individuals with SMI receiving services at 18 mental health organizations throughout the continental U.S. completed questionnaires on their community participation, civic engagement, quality of life, loneliness, and psychiatric symptoms. They were also asked which social media sites they used; the duration, frequency and importance of, and reasons for, social media use; and the number of contacts they had on social media.ResultsApproximately a third of the sample reported having at least one social media account. Greater frequency, intensity and longevity of social media were associated with higher levels of community participation, and greater intensity of social media use was positively associated with civic engagement. For instance, those who used social media at least 30 min a day had 16.4 more days of participation and voting rates that were higher by 17.4%. Social media use was not found to be significantly associated with loneliness, psychiatric symptoms or quality of life.Discussion and implicationsGreater social media use appears to be associated with greater community engagement without negative repercussions on loneliness, symptoms, or quality of life. Interventions that support social media use among individuals with SMI could have important community integration benefits.     

Detecting discussion communities on vaccination in twitter

Vaccines have contributed to dramatically decrease mortality from infectious diseases in the 20th century. However, several social discussion groups related to vaccines have emerged, influencing the opinion of the population about vaccination for the past 20 years. These communities discussing on vaccines have taken advantage of social media to effectively disseminate their theories. Nowadays, recent outbreaks of preventable diseases such as measles, polio, or influenza, have shown the effect of a decrease in vaccination rates. Social Networks are one of the most important sources of Big Data. Specifically, Twitter generates over 400 million tweets every day. Data mining provides the necessary algorithms and techniques to analyse massive data and to discover new knowledge. This work proposes the use of these techniques to detect and track discussion communities on vaccination arising from Social Networks. Firstly, a preliminary analysis using data from Twitter and official vaccination coverage rates is performed, showing how vaccine opinions of Twitter users can influence over vaccination decision-making. Then, algorithms for community detection are applied to discover user groups opining about vaccines. The experimental results show that these techniques can be used to discover social discussion communities providing useful information to improve immunization strategies. Public Healthcare Organizations may try to use the detection and tracking of these social communities to avoid or mitigate new outbreaks of eradicated diseases.
