    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

    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

    BACKGROUND: The dental arch form evaluation has become an important part of the orthodontic treatment planning.The way the teeth are aligned on the basal bone determines the archform of an individual. In fact, theArchform varies between two groups and two individuals of the same group.Differences in the archform are seen between males and females. Mismatch of archform leads to expansion or contraction of archforms and hence a relapse of the corrected malocclusion due to functional instability or structural imbalance is a possibility. Evaluating the archform of an individual plays a key role for an Orthodontist in treatment planning and attaining a greater post treatment stability. OBJECTIVES: To asses dental arch form amongdifferent classes of angle’s malocclusions on dental cast of orthodontic patients treated in jimma medical center dental clinic orthodontic unit,jimma, south west Ethiopia, 2022. METHODS;A two years hospital based retrospective cross-sectional study design was conducted to assess arch form of orthodontic patients in jimma university dental clinic fromFebruary to May 2022.Data was collected by reviewing the medical record of patients who visited the orthodontic clinic from February 2020 to March 2022.the dental casts of patients who fulfill inclusion criteria was selected from a pool of available models at orthodontic clinic.Digitalvernier caliper will be used for measurements .The collected data was cleaned, coded and entered to Statistical Package for Social (SPSS version 24) windows software computer program for analysis.SD,mean,T-test and chi square were used to analyze the results. RESULT AND DISCUSSION:The commonest arch form is Ovoid in both arches (upper arch(44.9%) and lower arch(45.7) followed by Tapered and Square arch form; Among gender females has higher in ovoid and tapered arch form, in contrary males has higher in square arch form. The results of this study showed that the commonest class was class I (51.2%), followed by class II (33.9%) and class III (14.9%). Significantly, more females had Class I (p<0.01) and Class II (p<0.05) occlusal relationship compared with males. In upper arch Class III arches is narrower than Class I and Class II dental arches are the widest (p<0.05). In lower arch Class II arches, are Wider than Class I and Class III dental arches. CONCLUSION AND RECOMMENDATION:The most frequently seen arch form in maxillary arch was the Ovoid (44.9%) and Tapered (30.7% ). the least frequent one was the square one which is recorded 24.4%. 6.5%.In mandibular arch 30.7% of subjects have tapered and 45.7% ovoid. the least common arch form is the square which is recorded in 23.6%.The commonest class was class I (51.2%), followed by class II (33.9%) and class III (14.9%). Significantly, more females had Class I (p<0.01) and Class II (p<0.05) occlusal relationship compared with males. more females had Class III relation compared with males. The mean values of all width and depth measurements were higher in males than in females in both arch. the professional’s should select the proper arch wire form based on individual patients arch forms.Further studies is still needed to overcome the limitations of this study which includes studying a larger sample and including other methods of arch form determination and different age groups are needed before the results of the present study can be applied on Ethiopian populatio
