Young people as global citizens: negotiation of youth civic participation in adult-managed online spaces

With the proliferation of new media technologies, online spaces for civic engagement are being used as new sites by the young people for enacting global citizenship. Some of these online civic spaces are managed by parent organizations and guide the participants towards accomplishing goals that align with the institutional policies. We use Stuart Hall’s theoretical framework to ground the two methods we used for empirical research- textual analysis of the selected online spaces and in-depth interviews with young bloggers. Our analysis shows how negotiated reading of the encoded messages on the online platforms for youth civic engagement marks a political moment of signification in which there lies a possibility of challenging the dominance of the adult centered notions of civic engagement. Shelat’s online civic culture framework [2014. “Citizens, Global Civic Engagement on Online Platforms: Women as Transcultural Citizens.” Dissertation] helped us examine how these managed platforms encode global citizenship with pre-designed participatory practices that reinforce the hegemonic definition of youth political participation. Interviews of young bloggers on two online global spaces foreground the process of negotiation with the dominant definitions and the use of decoding strategies to create scope for subjective, more local definitions, as well as practices of civic engagement and global citizenship. Though literature suggests that adult-management of online youth spaces perpetuate a gap between the adult-centric notions of participation and the youth oriented ideas of civic engagement, our study reveals that the young participants find ways of articulating their ideas and enter these spaces with plans on how to fulfill their civic goals.

Rock is a Way of Life: The World of Rock ‘n’ Roll Fanzines and Fandom

Abstract

While advantages of electronic publications are obvious and far reaching, most electronic journals are still published also in print since libraries do not acquire electronic journals but only access them through licenses. Libraries with substantial electronic publications, however, no longer “compile” collections in a traditional sense. One consequence of electronic only access is that the permanent availability of information that implicitly used to be found in print collections is no longer guaranteed. Digital publishing dramatically alters both the roles of libraries and publishers in preserving records of science. This article discusses the contribution of national libraries, particularly the Koninklijke Bibliotheek (KB; National Library of the Netherlands), to cooperate with publishers to secure the permanent archiving of electronic publications.

A Framework for Assessing Uncertainty Associated with Human Health Risks from MSW Landfill Leachate Contamination

Landfilling is a cost‐effective method, which makes it a widely used practice around the world, especially in developing countries. However, because of the improper management of landfills, high leachate leakage can have adverse impacts on soils, plants, groundwater, aquatic organisms, and, subsequently, human health. A comprehensive survey of the literature finds that the probabilistic quantification of uncertainty based on estimations of the human health risks due to landfill leachate contamination has rarely been reported. Hence, in the present study, the uncertainty about the human health risks from municipal solid waste landfill leachate contamination to children and adults was quantified to investigate its long‐term risks by using a Monte Carlo simulation framework for selected heavy metals. The Turbhe sanitary landfill of Navi Mumbai, India, which was commissioned in the recent past, was selected to understand the fate and transport of heavy metals in leachate. A large residential area is located near the site, which makes the risk assessment problem both crucial and challenging. In this article, an integral approach in the form of a framework has been proposed to quantify the uncertainty that is intrinsic to human health risk estimation. A set of nonparametric cubic splines was fitted to identify the nonlinear seasonal trend in leachate quality parameters. LandSim 2.5, a landfill simulator, was used to simulate the landfill activities for various time slices, and further uncertainty in noncarcinogenic human health risk was estimated using a Monte Carlo simulation followed by univariate and multivariate sensitivity analyses.     

Rethinking Learning Disabilities in the College Classroom: A Multicultural Perspective

This exploratory, qualitative study examined the opinions of social work faculty/instructors on teaching multicultural content with the inclusion of individuals with learning disabilities. It seeks to create a framework for understanding learning disabilities within the definition of a multicultural population and diversity in order to create a more inclusive educational atmosphere that relinquishes the focus on individual deficits that has long been the standard of education policy. This phenomenological research supports the groundbreaking work of Gilson and DePoy, who define individuals with disabilities as being inclusive in the definition of multicultural diverse groups, often termed unique cultures; these individuals, possessing shared life experiences peculiar to that group, possess unique social status, rules, and languages. Three hundred and twenty-six surveys were returned as completed from a state stratified selection method used to ensure accurate representation of social work educators nationally. The phenomenological format, which focuses on the individual's experiences, gives voice to individuals who might not otherwise have a voice. Adult Learning Theory is utilized as the framework to understand educational contexts that illuminate learning culture in higher education and support LD as a genuine population for inclusion in the diversity schema. Historical oversight of including individuals with LD in the definition of multicultural diverse groups is discussed and reasons for the oversight are explained. National social work faculty/instructors were surveyed and an exploratory survey was constructed to compare teaching of multicultural content. Ten multicultural diverse groups were defined, with the inclusion of individuals with LD, and qualitative questions were created and responses were coded into themes. Findings, implications, and limitations of the study are discussed along with supporting suggestions for more social work research concerning individuals with learning disabilities.     

What's All this Talk About Emotion? Developing Emotional Intelligence in Social Work Students

The capacity to manage emotional reactions effectively, frequently in complex care settings, is central to the role of a social worker. Nonetheless, there is evidence that social work students frequently find their placements emotionally demanding and stressful. It is proposed that emotional intelligence may help students manage their emotional reactions more effectively during placements and their subsequent career. To date, however, little systematic research has explored whether emotional intelligence and associated competencies can be enhanced during social work training and the implications for wellbeing. This paper presents a mixed-methods two-stage study which aimed to increase emotional competencies in social work students during the first year of training. More specifically, it assesses the impact of a workshop designed to enhance emotional competencies and an emotional writing task on levels of emotional intelligence, reflective ability and empathy which were assessed via questionnaire and reflective logs pre- and post-intervention (Times 1 and 2). Levels of reflective ability and empathy increased significantly between Times 1 and 2 and psychological distress decreased. Content analysis of reflective logs found evidence that reflective ability, empathy and emotional intelligence were enhanced following the interventions. The implications of the findings for the development of the curriculum are considered.     

Sojourning With the Homogeneous Poisson Process

In this pedagogical article, distributional properties, some surprising, pertaining to the homogeneous Poisson process (HPP), when observed over a possibly random window, are presented. Properties of the gap-time that covered the termination time and the correlations among gap-times of the observed events are obtained. Inference procedures, such as estimation and model validation, based on event occurrence data over the observation window, are also presented. We envision that through the results in this article, a better appreciation of the subtleties involved in the modeling and analysis of recurrent events data will ensue, since the HPP is arguably one of the simplest among recurrent event models. In addition, the use of the theorem of total probability, Bayes’ theorem, the iterated rules of expectation, variance and covariance, and the renewal equation could be illustrative when teaching distribution theory, mathematical statistics, and stochastic processes at both the undergraduate and graduate levels. This article is targeted toward both instructors and students.     

Homophily of music listening in online social networks of China

Homophily, ranging from demographics to sentiments, breeds connections in social networks, either offline or online. However, with the prosperous growth of music streaming services, whether homophily exists in online music listening remains unclear. In this study, two online social networks of the same group of active users who listened to complete songs over 1000 times and posted over 100 tweets are established, separately, in Netease Music and Weibo. Through presented multiple similarity measures, it is evidently demonstrated that homophily does exist in music listening for both online social networks. The unexpected listening similarity in Weibo also implies that knowledge from generic social networks can be confidently transferred to domain-oriented networks for context enrichment and algorithm enhancement. Comprehensive factors that might function in the formation of homophily are further probed, and many interesting patterns are profoundly revealed. It is found that female friends are more homogeneous in music listening and that positive and energetic songs significantly pull users close. Our methodology and findings shed light on realistic applications in online music services.
