The spread of ideas is a fundamental concern of today’s news ecology. Understanding the dynamics of the spread of information and its co-option by interested parties is of critical importance. Research on this topic has shown that individuals tend to cluster in echo-chambers and are driven by confirmation bias. In this paper, we leverage the active inference framework to provide an in silico model of confirmation bias and its effect on echo-chamber formation. We build a model based on active inference, where agents tend to sample information in order to justify their own view of reality, which eventually leads to them to have a high degree of certainty about their own beliefs. We show that, once agents have reached a certain level of certainty about their beliefs, it becomes very difficult to get them to change their views. This system of self-confirming beliefs is upheld and reinforced by the evolving relationship between agent's beliefs and its observations, which over time will continue to provide evidence for their ingrained ideas about the world. The epistemic communities that are consolidated by these shared beliefs, in turn, tend to produce perceptions of reality that reinforce those shared beliefs. We provide an active inference account of this community formation mechanism. We postulate that agents are driven by the epistemic value that they obtain from sampling or observing the behaviors of other agents. Inspired by digital social networks like Twitter, we build a generative model in which agents generate observable social claims or posts (e.g. `tweets') while reading the socially-observable claims of other agents, that lend support towards one of two mutually-exclusive abstract topics. Agents can choose which other agent they pay attention to at each timestep, and crucially who they attend to and what they choose to read influences their beliefs about the world. Agents also assess their local network’s perspective, influencing which kinds of posts they expect to see other agents making. The model was built and simulated simulated using the freely-available Python package pymdp. The proposed active inference model can reproduce the formation of echo-chambers over social networks, and gives us insight into the cognitive processes that lead to this phenomenon.

This article investigates a community of men who use the pharmaceuticals Minoxidil and Finasteride to enable and restore beard and hair growth, and who track and trace the effects on YouTube. It argues that the traditional positions of expert and patient are deterritorialized by the digitalization of health discourses and practices, and that the camera in these YouTube videos acts as a mediating/performative factor. The article seeks to answer the question of community formation among the male self-trackers. It offers a generic, analytical model where knowledge production is outlined as either expert or practitioner and community formation as either community member or community leader, both of which figure as intersecting axes on a continuum. Although derived from the case material, the article suggests that the generic, analytical model works across different audiovisually mediated selftracking communities and practices.

This study presents the significance of trust for the formation of an Open Source Software Development (OSSD) community. OSSD has various challenges that must be overcome for its successful operation. First is the development of a community, which requires a healthy community formation environment. Taking into consideration various factors for community formation, a strong sense of TRUST among its members has been felt. Trust development is a slow process with various methods for building and maintaining it. OSSD is teamwork but the team is of unknowns and volunteers. Trust forms a pillar for effective cooperation, which leads to a reduction in conflicts and risks, associated with quality software development. This study offers an overview of various existing trust models, which aids in the development of a trust evaluation framework for OSSD communities. Towards the end of the study, various components of the trust evaluation along with an empirical framework for the same have been proposed.

The assembly and maintenance of microbial diversity in natural communities, despite the abundance of toxin-based antagonistic interactions, presents major challenges for biological understanding. A common framework for investigating such antagonistic interactions involves cyclic dominance games with pairwise interactions. The incorporation of higher-order interactions in such models permits increased levels of microbial diversity, especially in communities in which antibiotic-producing, sensitive, and resistant strains coexist. However, most such models involve a small number of discrete species, assume a notion of pure cyclic dominance, and focus on low mutation rate regimes, none of which well represent the highly interlinked, quickly evolving, and continuous nature of microbial phenotypic space. Here, we present an alternative vision of spatial dynamics for microbial communities based on antagonistic interactions—one in which a large number of species interact in continuous phenotypic space, are capable of rapid mutation, and engage in both direct and higher-order interactions mediated by production of and resistance to antibiotics. Focusing on toxin production, vulnerability, and inhibition among species, we observe highly divergent patterns of diversity and spatial community dynamics. We find that species interaction constraints (rather than mobility) best predict spatiotemporal disturbance regimes, whereas community formation time, mobility, and mutation size best explain patterns of diversity. We also report an intriguing relationship among community formation time, spatial disturbance regimes, and diversity dynamics. This relationship, which suggests that both higher-order interactions and rapid evolution are critical for the origin and maintenance of microbial diversity, has broad-ranging links to the maintenance of diversity in other systems.

An international conference was held from December 6 to 8 2016 at Adeyemi College of Education Ondo, with the theme “Mobile Populations, Fluid Boundaries: Community, Trade and Religion in Coastal Yorubaland and the Western Niger Delta.” The conference was sponsored by the European Research Council (ERC), and jointly organized by the University of Birmingham, Osun State University, and Adeyemi College of Education. Over a period of three days, many papers were presented, covering various topics and issues on mythologies, oral traditions, religion, making sense of the Yoruba littoral, economy and intergroup relations in the Gulf of Guinea during the 18th and 19th centuries, trade on the north eastern bank of the Lagos lagoon, history, religion and community formation, moral traditions of the Yoruba and non-Yoruba speaking groups, and many more.

Abstract This paper explores colonial modernity and the knowledge system’s role in constituting community formation among the Mappilas of Malabar. Colonial modernity, such as the introduction of printing, made this transformation more advanced and communitarian in structure. It also discusses colonialism as a force to reshape and bring socio-cultural changes in Malabar during the time. It argues that the existence of a clearly defined community is not a predetermined social fact; it looks at how the Mappilas were represented in an analytical category. In Malabar, the press and literature have played an essential role in framing community consciousness among Mappila society. Print media has brought a revolution in the transmission of knowledge. This paper will encompass the coming of the printing press and the moulding of community consciousness among the Mappilas of Malabar. It discusses the discursive and non-discursive practices of the colonial state for constructing various identities in Malabar.

Abstract The Holy Spirit plays a significant role in 1 Corinthians. Paul discusses the role of the Spirit in personal lives, community formation, and worship, among other aspects of Christian living. Paul’s teaching about the Holy Spirit in 1 Corinthians cannot be understood apart from the situation of the congregation in Corinth. It is not possible to address every issue related to the Holy Spirit in an essay of this length. However, Paul highlights and sometimes elaborates on different aspects of the ministry and function of the Holy Spirit among believers in several passages. Therefore, the approach in this essay is to look at some of the passages and see how much they foster the understanding of the Holy Spirit’s work in 1 Corinthians.

Future manned space travel will require efficient recycling of nutrients from organic waste back into food production. Microbial systems are a low-energy, efficient means of nutrient recycling, but their use in a life support system requires predictability and reproducibility in community formation and reactor performance. To assess the reproducibility of microbial community formation in fixed-film reactors, we inoculated replicate anaerobic reactors from two methanogenic inocula: a lab-scale fixed-film, plug-flow anaerobic reactor and an acidic transitional fen. Reactors were operated under identical conditions, and we assessed reactor performance and used 16s rDNA amplicon sequencing to determine microbial community formation. Reactor microbial communities were dominated by similar groups, but differences in community membership persisted in reactors inoculated from different sources. Reactor performance overlapped, suggesting a convergence of both reactor communities and organic matter mineralization. The results of this study suggest an optimized microbial community could be preserved and used to start new, or restart failed, anaerobic reactors in a life support system with predictable reactor performance.

In the last decades, migration from Latin America to Canada has become a topic of interest for Canadian scholars, policy decision-makers that look after the well-being of this population as well as for community members themselves. The nature of Latino immigration to Canada is continuously changing, and so does how the integration of these immigrants to Canada is interpreted and problematized. Using yearly immigration statistics and 2016 Census data, the author looks at the 1965-2015 and 1981-2016 periods and explores the five major Latin American immigrant waves previously identified by Canadian scholars: the Eurolatino or Lead of the 1960s, the Andean and Coup of the 1970s, the Central American of the 1980s, and the Technological-Professional which started in the mid-1990s. A sixth additional Sustaining Latino immigrant wave is also identified. Immigrant waves are the product of particular historical international developments as well as changes in Canada's immigration policy. The paper briefly also examines the historical moments of Latino immigration to Canada, the socio-demographic composition of national immigrant inflows related to these immigrant waves, and reflects on how the immigrant selection process has affected immigration integration outcomes and community formation.

Bacteria can work as collectives to form multicellular communities. Vibrio cholerae , the bacterium that causes the disease cholera in humans, forms aggregated communities in liquid. Aggregate formation relies on a chemical communication process called quorum sensing.
