This paper explores a design study of a smartphone enabled meet-up app meant to inspire engagement in community innovation. Community hubs such as co-working spaces, incubators, and maker spaces attract community members with diverse interests. This paper presents these spaces as a design opportunity for an application that helps host community-centered meet-ups in smart and connected communities. Our design study explores three scenarios of use, inspired by previous literature, for organizing meet-ups and compares them by surveying potential users. Based on the results of our survey, we propose several design implications and implement them in the Community Animator geosocial networking application, which identifies nearby individuals that are willing to chat or perform community-centered activities. We present the results of both our survey and our prototype, discuss our design goals, and provide design implications for civic-minded, geosocial networking applications. Our contribution in this work is the development process, proposed design of a mobile application to support community-centered meet-ups, and insights for future work.

We apply spectral clustering and multislice modularity optimization to a Los Angeles Police Department field interview card data set. To detect communities (i.e., cohesive groups of vertices), we use both geographic and social information about stops involving street gang members in the LAPD district of Hollenbeck. We then compare the algorithmically detected communities with known gang identifications and argue that discrepancies are due to sparsity of social connections in the data as well as complex underlying sociological factors that blur distinctions between communities.
Many researchers studying online social communities seek to make such communities better. However, understanding what better means is challenging, due to the divergent opinions of community members, and the multitude of possible community values which often conflict with one another. Community members own values for their communities are not well understood, and how these values align with one another is an open question. Previous research has mostly focused on specific and comparatively well-defined harms within online communities, such as harassment, rule-breaking, and misinformation. In this work, we ask 39 community members on reddit to describe their values for their communities. We gather 301 responses in members own words, spanning 125 unique communities, and use iterative categorization to produce a taxonomy of 29 different community values across 9 major categories. We find that members value a broad range of topics ranging from technical features to the diversity of the community, and most frequently prioritize content quality. We identify important understudied topics such as content quality and community size, highlight where values conflict with one another, and call for research into governance methods for communities that protect vulnerable members.
While game-theoretic models and algorithms have been developed to combat illegal activities, such as poaching and over-fishing, in green security domains, none of the existing work considers the crucial aspect of community engagement: community members are recruited by law enforcement as informants and can provide valuable tips, e.g., the location of ongoing illegal activities, to assist patrols. We fill this gap and (i) introduce a novel two-stage security game model for community engagement, with a bipartite graph representing the informant-attacker social network and a level-$kappa$ response model for attackers inspired by cognitive hierarchy; (ii) provide complexity results and exact, approximate, and heuristic algorithms for selecting informants and allocating patrollers against level-$kappa$ ($kappa<infty$) attackers; (iii) provide a novel algorithm to find the optimal defender strategy against level-$infty$ attackers, which converts the problem of optimizing a parameterized fixed-point to a bi-level optimization problem, where the inner level is just a linear program, and the outer level has only a linear number of variables and a single linear constraint. We also evaluate the algorithms through extensive experiments.
Online platforms are an increasingly popular tool for people to produce, promote or sell their work. However recent studies indicate that social disparities and biases present in the real world might transfer to online platforms and could be exacerbated by seemingly harmless design choices on the site (e.g., recommendation systems or publicly visible success measures). In this paper we analyze an exclusive online community of teams of design professionals called Dribbble and investigate apparent differences in outcomes by gender. Overall, we find that men produce more work, and are able to show it to a larger audience thus receiving more likes. Some of this effect can be explained by the fact that women have different skills and design different images. Most importantly however, women and men position themselves differently in the Dribbble community. Our investigation of users position in the social network shows that women have more clustered and gender homophilous following relations, which leads them to have smaller and more closely knit social networks. Overall, our study demonstrates that looking behind the apparent patterns of gender inequalities in online markets with the help of social networks and product differentiation helps us to better understand gender differences in success and failure.
In this article we identify social communities among gang members in the Hollenbeck policing district in Los Angeles, based on sparse observations of a combination of social interactions and geographic locations of the individuals. This information, coming from LAPD Field Interview cards, is used to construct a similarity graph for the individuals. We use spectral clustering to identify clusters in the graph, corresponding to communities in Hollenbeck, and compare these with the LAPDs knowledge of the individuals gang membership. We discuss different ways of encoding the geosocial information using a graph structure and the influence on the resulting clusterings. Finally we analyze the robustness of this technique with respect to noisy and incomplete data, thereby providing suggestions about the relative importance of quantity versus quality of collected data.
