    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

    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

    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

    Effects of Color Plastic Mulches and Row Cover on the Yield and Quality of Sweet Potato [Ipomea batatas cv. ‘Beauregard’]

    Sweet potato [Ipomea batatas ‘Beauregard’] was grown on an Orangeburg sandy loam soil in Shorter AL. Sweet potato slips were planted in single rows. The experiment consisted of twelve experimental treatments as follows: (1) black plastic mulch (BPM) + spun-bonded row cover (RC), (2) BPM, (3) white plastic mulch (WPM) + RC, (4) WPM, (5) red plastic mulch (RPM) + RC, (6) RPM, (7) bare soil (BS) + RC, (8) BS, (9) silver plastic mulch (SPM) + RC, (10) SPM, (11) blue plastic mulch (BLUPM) + RC, (12) BLUPM. Soil temperatures were 6°F lower than above mulch temperatures in all treatments. Both early root yield and total root yield were different among the treatments with SPM + RC being the highest, followed by RPM. However, RPM treatments exhibited the highest nutritional properties in sweet potato roots when compared to other treatments. Further studies need to be perform to have a better understanding of the effects on yield and nutritional qualities of vegetable crops grown with row covers and various colored plastic mulches

    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

    Videoconference Use Predictors and Dynamics in Alabama’s Blackbelt Region

    Get PDF
    Utilizing videoconference platforms has become the norm for work and personal use. However, many adults need help accessing and using videoconference system platforms. The demographics with low videoconference system access and use numbers are adults living in low socioeconomic rural (LSR) communities such as Alabama's Blackbelt Region. The Alabama Blackbelt region is one of the poorest areas in the country, characterized by a predominantly African American population. LSR communities' use in technology is low due to several factors in the digital divide concepts such differences in digital skills and affordability of the internet. This study explores the dynamics behind LSR communities in rural Alabama's use with videoconference system platforms. This study seeks to gain insight and understanding into the predictors and dynamics behind the relationships between computer self-efficacy (CSE) and the Technology Acceptance Model 2 (TAM2) constructs in videoconferencing use among individuals living in the Blackbelt Region of Alabama. Two hundred and ninety-five adult participants residing in Macon County, Alabama, were surveyed during this study using a convenience sample. Results showed significant interactions with CSE among age, education attainment, and income levels. In addition, only actual use (AU), attitude towards use (ATT), and perceived ease of use (PEOU) were significant predictors of perceived levels of CSE among participants residing in Macon County, AL. Although these results show significant interactions, more research is needed on videoconference systems and the dynamics that affect their use in the Blackbelt region. The implications of videoconference systems research within the Blackbelt region have the potential to help significantly narrow the digital divide adding to research on technology use in low socio-economic rural populations
