Although the World Health Organization (WHO) recommends the use of a Community‐Based Rehabilitation (CBR) model, little is known about how CBR has been applied in the hearing healthcare setting. The ...purpose of this scoping review was to identify and describe studies on Community‐Based Hearing Rehabilitation (CBHR) programs within the applied context. The review was conducted in September 2020 with updated searches in November 2021 according to the Joanna Briggs Institute (JBI) methodology and reported using the guidelines and checklist for Preferred Reporting Items for Systematic Reviews and Meta Analyses‐Extension for Scoping Reviews (PRISMA‐ScR). Fifty‐nine peer‐reviewed research articles were included in the review. A narrative synthesis was conducted to map out the types of CBHR programs. Studies were classified into audiological themes: awareness, screening and assessment of hearing in newborn/infants, children and adults, training of community health workers, rehabilitation, cost‐effectiveness and describing the service delivery models. Further categorisation was made based on CBR aspect matrices for each study. Most of the studies come from high‐income countries in North America and Europe. CBHR studies predominantly focused on creating awareness, training and hearing screenings and/or assessments in communities and evaluating effectiveness in providing knowledge and access to hearing health services in rural or underserved communities. Further work is needed to examine the outcomes and effectiveness of CBHR using controlled studies. Moreover, more work is needed in low‐ and middle‐income countries where the application of CBHR is critical for increased access and affordability.
•Community interactions are positively associated with harmonious community relationships.•Harmonious community relationships enhance community identification.•Community interaction characteristics ...have positive interactive effect on community relationships.
As a proxy for the vitality of online brand community, effective interaction has always been viewed as a prerequisite for the formation of harmonious organization atmosphere and high degree of organizational identity. To investigate the process, this study proposes a model delineates the relationship among community interactions, harmonious community relationships, and customers’ community identification. The findings, based on 665 valid samples, reveal that different community interactions (product-information, human-computer, and interpersonal) have different effects on harmonious community relationships (customer-brand and customer-other customers’ relationships), which in turn influences customers’ identification with community. Furthermore, these community interactions have an interactive effect on harmonious community relationships. Based on the analytical results, this study concludes with some managerial and research implications.
This review outlines several key aspects or the new rural-urban interface and the growing interpenetration of American rural and urban life. The historical coincidence ot spatial and social ...boundaries in America is changing rapidly. This review highlights (a) the enormous scale of rural-urban interdependence and boundary crossing, shifting, and blurring—along many dimensions of community life—over the past several decades, and (b) the symmetrical rather than asymmetrical influences between urban and rural areas, i.e., on bidirectional relational aspects of spatial categories. These general points are illustrated by identifying 10 common conceptions of rural America that reflect both its social and economic diversity and its changing spatial and social boundaries. Here we emphasize symbolic and social boundaries—the distinctions between urban and rural communities and people and the processes by which boundaries are engaged. Placing behaviors or organizational forms along a rural-urban continuum (or within a metropolitan hierarchy of places) or drawing sharp rural-urban distinctions seems increasingly obsolete or even problematic. We conclude with a call for new research on rural America and greater conceptual and empirical integration of urban and rural scholarship, which remains disconnected and segregated institutionally.
Large-scale online communities rely on computer-mediated communication between participants, enabling them to sustain interactions and exchange on a scale hitherto unknown. Yet little research has ...focused on how these online communities sustain themselves and how their interactions are structured. In this paper, we theorize and empirically measure the network exchange patterns of long-duration sustainable online communities. We propose that participation dynamics follow specific forms of social exchange: direct reciprocity, indirect reciprocity, and preferential attachment. We integrate diverse findings about individual participation motivations by identifying how individual behavior manifests in network-level structures of online communities. We studied five online communities over 27 months and analyzed 38,483 interactions using exponential random graph (

) models and mixed-effects analysis of covariance. In a test of competing models, we found that network exchange patterns in online community communication networks are characterized by direct reciprocity and indirect reciprocity patterns and, surprisingly, a tendency away from preferential attachment. Our findings undermine previous explanations that online exchange follows a power law distribution based on people wanting to connect to "popular" others in online communities. Our work contributes to theories of new organizational forms by identifying network exchange patterns that regulate participation and sustain online communities.
A large array of species distribution model (SDM) approaches has been developed for explaining and predicting the occurrences of individual species or species assemblages. Given the wealth of ...existing models, it is unclear which models perform best for interpolation or extrapolation of existing data sets, particularly when one is concerned with species assemblages. We compared the predictive performance of 33 variants of 15 widely applied and recently emerged SDMs in the context of multispecies data, including both joint SDMs that model multiple species together, and stacked SDMs that model each species individually combining the predictions afterward. We offer a comprehensive evaluation of these SDM approaches by examining their performance in predicting withheld empirical validation data of different sizes representing five different taxonomic groups, and for prediction tasks related to both interpolation and extrapolation. We measure predictive performance by 12 measures of accuracy, discrimination power, calibration, and precision of predictions, for the biological levels of species occurrence, species richness, and community composition. Our results show large variation among the models in their predictive performance, especially for communities comprising many species that are rare. The results do not reveal any major trade-offs among measures of model performance; the same models performed generally well in terms of accuracy, discrimination, and calibration, and for the biological levels of individual species, species richness, and community composition. In contrast, the models that gave the most precise predictions were not well calibrated, suggesting that poorly performing models can make overconfident predictions. However, none of the models performed well for all prediction tasks. As a general strategy, we therefore propose that researchers fit a small set of models showing complementary performance, and then apply a cross-validation procedure involving separate data to establish which of these models performs best for the goal of the study.
Gay and bisexual men might face unique, status-based competitive pressures given that their social and sexual relationships often occur with other men, who are known to compete for social and sexual ...gain. In a multistage study, we delineated intraminority gay community stress theory-that status-focused elements of the gay community challenge the mental health of gay and bisexual men. We first created a measure of gay community stress with items derived from qualitative interviewing (n = 49); calculated its psychometric properties, including 1-year temporal stability (n = 937); and confirmed its structural stability in distinct samples (n = 96; n = 1,413). Being stressed by perceiving the gay community's focus on sex, focus on status, focus on competition, and exclusion of diversity predicted gay and bisexual men's mental health over-and-above a comprehensive battery of traditional minority stressors (β = .17, p < .01) and mediated the association between one's gay community status and mental health. To examine the impact of individual differences in status concerns (i.e., about masculinity, attractiveness, and wealth) on gay and bisexual men's feelings of within-community exclusion, a series of experiments manipulated (a) the sexual orientation (gay vs. heterosexual) of rejecters (n = 103), (b) the social status of gay rejecters (n = 83), and (c) whether rejection from gay and bisexual rejecters was status-based or nonstatus-based (n = 252). Overall, these experiments provide partial support for the possibility that gay and bisexual men's status concerns underlie their experience of gay community stress. Together, these studies advance psychological and sociological accounts of gay and bisexual men's mental health beyond minority stress theory, with implications for intervention.
Teacher communities play a central role in teachers' professional development. This study provides a systematic review of empirical research on teacher communities (TCs). Based upon predefined ...selection criteria, 40 studies were analysed using a narrative method. Three different types of TCs were identified: formal, member-oriented with a pre-set agenda, and formative TCs. Results showed that different stakeholders (governments, school principals, teachers) are involved and their different perspectives and degrees of involvement (distinguishing between TCs realised bottom-up or top-down) impact TCs. Finally, several conditions for success were reported: supportive leadership, group dynamics and composition, and trust and respect.
•Community appears to be a fuzzy concept, in literature and practice.•Three different types of teacher communities (TCs) can be distinguished.•The presence of different stakeholders influences the functioning of TCs.•Conditions for TCs' success include leadership, group dynamics, trust, and respect.
Microbial communities transform nitrogen (N) compounds, thereby regulating the availability of N in soil. The N cycle is defined by interacting microbial functional groups, as inorganic N‐products ...formed in one process are the substrate in one or several other processes. The nitrification pathway is often a two‐step process in which bacterial or archaeal communities oxidize ammonia to nitrite, and bacterial communities further oxidize nitrite to nitrate. Little is known about the significance of interactions between ammonia‐oxidizing bacteria (AOB) and archaea (AOA) and nitrite‐oxidizing bacterial communities (NOB) in determining the spatial variation of overall nitrifier community structure. We hypothesize that nonrandom associations exist between different AO and NOB lineages that, along with edaphic factors, shape field‐scale spatial patterns of nitrifying communities. To address this, we sequenced and quantified the abundance of AOA, AOB, and Nitrospira and Nitrobacter NOB communities across a 44‐hectare site with agricultural fields. The abundance of Nitrobacter communities was significantly associated only with AOB abundance, while that of Nitrospira was correlated to AOA. Network analysis and geostatistical modelling revealed distinct modules of co‐occurring AO and NOB groups occupying disparate areas, with each module dominated by different lineages and associated with different edaphic factors. Local communities were characterized by a high proportion of module‐connecting versus module‐hub nodes, indicating that nitrifier assemblages in these soils are shaped by fluctuating conditions. Overall, our results demonstrate the utility of network analysis in accounting for potential biotic interactions that define the niche space of nitrifying communities at scales compatible to soil management.
The concept of epistemic communities – professional networks with authoritative and policy-relevant expertise – is well-known thanks to a 1992 special issue of International Organization. Over the ...past twenty years, the idea has gained some traction in International Relations scholarship, but has not evolved much beyond its original conceptualisation. Much of the research on epistemic communities has been limited to single case studies in articles, rather than broader comparative works, and has focused narrowly on groups of scientists. As a result, it is often assumed, erroneously, that epistemic communities are only comprised of scientists, and that the utility of the concept for understanding International Relations is quite narrow. Consequently, an otherwise promising approach to transnational networks has become somewhat marginalised over the years. This article revisits the concept of epistemic communities twenty years later and proposes specific innovations to the framework. In an increasingly globalising world, transnational actors are becoming progressively more numerous and influential. Epistemic communities are certainly at the forefront of these trends, and a better understanding of how they form and operate can give us a clear demonstration of how knowledge translates into power.
