Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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
Impact of COVID-19 Pandemic on the Outcomes in Patients With Critical Limb Threatening Ischaemia and Diabetic Foot Infection
No full textOBJECTIVE: Examine the impact of COVID-19 pandemic on the outcomes in patients with CLTI or DFI. BACKGROUND: Patients with CLTI and/or DFI are at risk of amputations if not treated in a timely manner. METHODS: We compared the outcomes in patients with CLTI or DFI during 2 periods; Period 1[P1] (15/03/2019-31/05/2019) and period 2[P2] (15/03/ 2020-31/05/2020- corresponding to COVID-19 pandemic). RESULTS: One hundred thirty-nine patients were treated in P1 [mean age 70 years (±11), Male:Female = 102:37] whereas 95 patients were treated in P2 [mean age 67 (±12), Male:Female = 64:31]. The 2 cohorts were matched regarding Rutherford category (P = 0.25) and GLASS classification (P = 0.38). Notably, the time from onset of symptom to clinical presentation was significantly longer [31 (1-105) days vs 27 (0–78) days, (P = 0.017)], whereas the time from presentation to first intervention was significantly shorter [3 (0–61) days vs 5 (0–65) days, (P = 0.013)] in P2 compared to P1. There was a significantly higher white cell count (P = 0.014) and CRP (P = 0.004) on admission in P2. Having treatment for CLTI or DFI in P2 was an independent predictor of worse primary patency rate and freedom from major adverse limb events. At 90 days, amputation-free survival and limb salvage were noticeably worse in P2 compared to P1 (amputation-free survival was 80% and 87% whereas limb salvage was 64% and 72% in P2 and P1, respectively). CONCLUSIONS: Patients with CLTI and DFI experienced a significantly delayed presentation with features of sepsis on admission in P2. Treatment in P2 was a predictor of worse primary patency and freedom from major adverse limb events and therefore close and long follow-up is advisable
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
LGBTQ Youth of Color in the School-to-Prison Pipeline: Freedom, Liberation, and Resistance
Full text linkAbstract: Emergent research suggests Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ) youth experience increased discipline in school, as well as increased exposure to the criminal justice system outside of school. Additionally, much has been written in recent years about the school-to-prison pipeline’s (StPP) impact upon large numbers of youth of color in the United States. However, a large portion of the existing research regarding the StPP often presumes heterosexuality in dealing with student populations. Further, what research exists on queer and transgender youth in schools often fails to address race in any meaningful way, thus misleading people to assume that the problems facing LGBTQ youth are racially neutral in nature. This paper seeks to synthesize some of the systemic factors that propel school pushout and student criminalization, and impact intersectionally-marginalized student populations like LGBTQ youth of color, as well as pose some possible critical pedagogical interventions in resisting the criminalization of these students under an increased neoliberal governmentality
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
