    The impact of undergraduate students' perceived social media empowerment in their engagement in sustainability practices: a predictive study

    Undeniably, the contemporary world is amid a digital revolution, where digital technology has emerged as a powerful, transformative tool that fosters engagement in sustainability initiatives. In light of that contention, this predictive study explored social media empowerment through participation and engagement, access to resources and support, and self-expression and control, analysing their influence on students' engagement in sustainability practices. Based on the quantitative approach and cross-sectional design, pertinent data were collected from 510 undergraduate students using a closed-ended self-developed questionnaire. Subsequently, the collected numerical data were subjected to quantitative analysis, employing descriptive and inferential analysis. The three hypotheses developed were tested using structural equation modelling (SEM). The study findings revealed that all three hypotheses were accepted, establishing a positive and statistically significant relationship between social media empowerment and students' perceived engagement in sustainability practices. While all exogenous constructs influenced endogenous constructs, their magnitude of impact varied. The construct of participation and engagement (β=0.311, p<.0001, R2=0.469) depicted the highest predictive power, followed by access to resources and support (β=0.106, p=0.041, R2=0.210). The construct of self-expression and control (β=0.319, p<.0001, R2=0.102) established the lowest predictive power. Therefore, the observed variation underscores the differential role of each construct in enhancing students' engagement in sustainability practices. The findings signify the importance of comprehensive approaches in promoting sustainable practices among undergraduate students through meaningful engagement on social media

    Unpacking the value-effect gap: university students' engagement with social media in academic and social context

    Social media use (SMU) for the youth, including university students, holds socio-psychological values, yet its dual impact on social and academic engagement remains underexplored, particularly in Tanzania's higher education. This study employed uses and gratifications theory (UGT) to investigate the value-effect gap of SMU, examining its perceived influence on academic connections (AC), personal friendships (PF), and overall socio-psychological values. Employing a quantitative approach, it collected data from 680 conveniently sampled university students at one of the largest public universities in central Tanzania, using online surveys. The collected data were analysed using descriptive and structural equation modelling (SEM) strategies. The findings revealed that most participants were social media consumers and WhatsApp dominated the SMU (74.41%). Descriptive analysis confirms high agreement of academic values (M ≈ 3.88–4.21), compared to high to moderate social values (M ≈ 3.37–3.89). Interestingly, SEM results demonstrated deeper, structural relationships thus confirming very strong effects of PF on overall perceived impact (OP) of SMU (PF → OP = 0.85; β = 0.852, p < 0.0001), compared to moderate path (AC \rightarrow OP = 0.43; β = 0.429, p < 0.0001). These findings confirm the value-effect gap related to SMU, implying that what is highly valued is not what mainly influences the overall perceived impact of SMU. Furthermore, the findings also demonstrated that SMU fulfil the dual role of academic and social bonding. In addition, demographic variables, particularly gender (β = 0.027, CR = 0.878, p = 0.380), demonstrated minimal influence on socio-psychological values of SMU. These findings contribute to efforts related to integrating social media in university campus life by elucidating context-specific motivations, thus informing policy by advocating holistic-balanced SMU integration in higher education. Recommendations include platform-specific guidelines and digital literacy programmes to optimise academic and social outcomes

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
