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
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
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
Relations Between Serum Antibodies to Herpes Simplex Viruses and Sustained Attention in Schizophrenic Patients and Their Families
No full text目的： 探討精神分裂症病患家族成員及對照組家族成員之單純疱疹病毒第一型(herpes simplex virus type 1, HSV-1)、第二型(HSV-2)血清學特徵與持續注意力之相關性。
方法： 自2002年至2004年收集三類研究對象，包括：117位精神分裂症指標個案及其257位一等親屬、44位對照家族指標個案及其44位母親、以及317位無血緣關係之對照個案。針對所有研究個案提供之血液檢體，利用固相酵素免疫分析(solid-phase enzyme immunoassay)進行HSV-1及HSV-2血清抗體G型免疫球蛋白之效價檢驗。部分的家族成員另外施予連續操作測驗(continuous performance test)以測量其持續注意力。統計分析方面，分別比較精神分裂症病患家族成員及對照組家族成員之單純疱疹病毒血清學特徵與持續注意力。家族內成員的共同感染情形，藉由合適的相關係數指標予以量化：類別性的感染狀態之相關程度以tetrachoric correlation呈現，而連續性的抗體效價則以intraclass correlation coefficient呈現。
結果： 血清學特徵的比較中，發現精神分裂症病患及其母親比起對照指標個案及其母親有顯著較高的HSV-2抗體效價，而HSV-1之效價則未發現有顯著差異。以精神分裂症病患的病毒抗體效價平均值作為切點，將精神分裂症指標個案及其各類一等親屬分為高效價組與低效價組，比較結果發現僅在精神分裂症病患中HSV-1高效價組呈現顯著較差的持續注意力，一等親屬中則皆未見此差異。於是進一步利用持續注意力分數將精神分裂症病患分成三等分並分析HSV-1抗體效價之分佈，結果得到隨注意力分數越高其抗體效價越低的線性趨勢。關於家族內成員HSV-1感染狀態的相關，精神分裂症指標個案及其無病手足之間相關程度很高，而精神分裂症指標個案及其母親之間則呈現中等的相關程度。
結論： 精神分裂症病患之HSV-1血清抗體與持續注意力有所相關，且此HSV-1感染可能源於家族內的共同感染。Objective: To evaluate the relations between the serological characteristics to herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) and sustained attention deficits in subjects of schizophrenic families and those of control families.
Methods: We recruited 117 schizophrenic probands and their 257 first-degree relatives, 44 control probands and their 44 mothers, and 317 unrelated population controls during the period of 2002 to 2004. Each participant’s serum immunoglobulin G class antibody titers to HSV-1 and HSV-2 were detected by means of solid-phase enzyme immunoassay with type-specific antigens, whereas part of the participants further undertook two sessions of the Continuous Performance Test (CPT). Members of the two types of families were compared for both HSV serological characteristics and CPT performance, and familial correlation in HSV infection was examined in tetrachoric correlation for categorical serostatus and in intraclass correlation coefficient for continuous antibody titers.
Results: Schizophrenic probands and their mothers had higher HSV-2 antibody titers than their counterparts in the control families, whereas no difference was found for HSV-1. When the mean antibody level of schizophrenic patients was used as the cut-off for the dichotomization of schizophrenic probands and their first-degree relatives, only patients with high HSV-1 titers were found to have poorer scores on the degraded CPT whereas other family members did not exhibit such differences. A linearly decreasing trend in HSV-1 antibody titers was further demonstrated when schizophrenic patients were trichotomized in terms of CPT scores. Prominent familial correlation in HSV-1 serostatus existed between schizophrenic probands and siblings, while moderate correlation between schizophrenic probands and mothers.
Conclusion: Our results indicate that the antibody titers to HSV-1 is associated with sustained attention deficits in schizophrenia and the infection is likely to be family-originated.CONTENT
