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
The potential of cardiac troponins I and T, CK-MB and NT-proANP as biomarkers of cardiac stress in farmed Atlantic salmon (Salmo salar)
Full text linkDenne oppgaven sammenlignet nivåer av hjertesviktsmarkører i Atlantisk laks (Salmo salar) fra en merd på Frøya før og etter transport til et slakteri på Averøy. Hensikten var å fastslå om stress i forbindelse med trenging, pumping og transport ville føre til skade på hjertet og påfølgende økning av hjertesviktsmarkører i blod. Konsentrasjon av hjertespesifikt troponin T, hjertespesifikt troponin I, CK-MB og NT-proANP i plasma fra laks ble målt ved å bruke Enzyme-Linked Immunosorbent Assay (ELISA). I tillegg ble det gjort en histopatologisk undersøkelse på hjertevev tatt fra Averøy for å undersøke den generelle helsetilstanden i populasjonen.
Troponin T økte signifikant fra Frøya til Averøy. Det var også en ikke-signifikant økning på troponin I og CK-MB i laks fra Averøy sammenlignet med Frøya. De hjertespesifikke troponinene og CK-MB i plasmaprøver både fra Frøya og Averøy var alle forhøyet i forhold til referanseverdiene for mennesker, noe som tyder på hjerteskade. Den histopatologiske undersøkelsen av hjertevevet fra laks fra Averøy viste epikarditt, myokarditt og nekroser. Sykdomsutbrudd av hjerte- og skjelettmuskelbetennelse (HSMB), pankreassykdom (PD) og mulig tilstedeværelse av kardiomyopatisyndrom (CMS) var påvist i merden før prøvetakingen. Året før ble laksen utsatt for flere mekaniske avlusninger, noe som er kjent for å utløse stressresponser. Dette forklarer hvorfor nivåer av hjertesviktsmarkører var forhøyet i merden før transport. Resultatene fra blodanalysene og histopatologien vitner om dårlig hjertehelse i populasjonen.This thesis compared cardiac biomarker levels in Atlantic salmon (Salmo salar) from a net pen at Frøya before and after transportation to a processing plant at Averøy. The objective was to determine if stress due to crowding, pumping and transportation would lead to heart damage and subsequent elevation of levels of cardiac markers in blood. Levels of cardiac troponin T, cardiac troponin I, CK-MB and NT-proANP in salmon plasma were measured using Enzyme-Linked Immunosorbent Assay (ELISA). Additionally, histopathological analysis was done on heart samples from Averøy to assess the overall health status of the population.
Troponin T increased significantly from Frøya to Averøy. Although non-significant, levels of cardiac troponin I and CK-MB were also increased at Averøy compared to Frøya. The cardiac troponins and CK-MB in plasma samples from both Frøya and Averøy were all elevated above the human reference ranges indicating cardiac damage. Histopathological examination of heart tissue from fish sampled at Averøy revealed epicarditis, myocarditis and necrosis. Outbreaks of heart and skeletal muscle inflammation (HSMI) and pancreas disease (PD) along with possible cardiomyopathy syndrome (CMS) were confirmed in the net pen at the time of sampling. The year before sampling, salmon were subjected to mechanical delousing treatments which are known to induce stress responses. This explains why levels of cardiac markers were elevated above normal in salmon from the net pen before transport. The results from the blood analyses and histopathology point to poor cardiovascular health in the sample population

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
