Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Evaluation and risk management model of human factors in ERP implementation projects
Get PDFProjekti implementacij ERP sistemov so znani po svoji kompleksnosti. Združujejo programske rešitve z različnimi poslovnimi procesi znotraj posameznih poslovnih področij oziroma branž, veliko različnih članov v okviru projektne skupine za implementacijo in različne interesne skupine znotraj in zunaj podjetja. Zato ne preseneča dejstvo, da projekti mnogokrat ne zagotovijo pogodbenih zahtev in poslovnih dogovorov. Veliko število avtorjev je posledično raziskovalo različne vzroke za velik odstotek neuspešnih implementacij. Projekt smatramo za uspešnega s poslovnega vidika, ko ga ocenimo z vidika upoštevanja terminov in proračuna ter dogovorjenega obsega in funkcionalnosti v primeru IT projektov. Poleg tega je vedno bolj pomemben četrti faktor, to je zadovoljstvo uporabnikov. Med različnimi kritičnimi dejavniki uspeha (KDU) je zadnje obdobje vedno več zanimanja za skupino človeških dejavnikov, ki ima evidentno velik vpliv in pomembno vlogo pri poteku in izidu projektov. Glavni namen raziskave je bil tako odkriti ključne vzroke, ki se skrivajo za velikim številom KDU in potencialno vplivajo na uspešnost projekta. Po temeljiti raziskavi obstoječe literature je bil razvit nov model primarnih človeških kritičnih dejavnikov, ki smo ga preverili z empirično raziskavo in statistično analizo. Spletna anketa je bila opravljena v različnih slovenskih podjetjih, ki so v preteklosti implementirale ERP sistem SAP. Rezultati so pokazali, da skupina človeških KDU kritično vpliva na uspeh projekta, znotraj raziskovalnega modela primarnih človeških dejavnikov pa imajo največji vpliv na uspešnost projekta Kompetence in Sestava projektnega tima. Ugotovitve in rezultati raziskave sovpadajo z zaključki ostalih raziskovalcev in nam ponudi pregled kritičnih človeških dejavnikov na drugačen, predvsem pa poenostavljen način, s katerim lahko nadziramo kompleksno sestavljene dejavnike uspeha. Magistrska naloga tako prikaže pomembnost primarnih človeških dejavnikov, ki nedvomno močno vplivajo na končni uspeh projektov in kaže pot od ustaljenega k spremenjenemu načinu implementacije, osredotočene k človeškim dejavnikom.ERP implementation projects are known for their complexity. They integrate software solutions with different business processes and branches, unite various project team members and many stakeholders. Not surprising, they often fail to deliver contract requirements and business agreements. Many researchers were therefore investigating different causes of unsuccessful implementations. To consider project successful in business terms we usually evaluate time, money and agreed scope and functionality, but there is also a fourth dimension, user satisfaction which is also very important factor. Among various critical success factors (CSFs), one cluster of factors is getting intensively investigated recently. This are human factors, which evidently play an important role in the course and outcome of a project. Main objective of research was to identify true causes behind numerous CSFs. After thorough research of literature the new model for evaluating critical success factors with primary human factors was proposed and explored by empirical research. A survey was conducted in various Slovenian companies, which implemented ERP system SAP. The main objective was to measure a level of primary human factors and verify influence on implementation project success. Results show that a group of human CSFs has the most important influence on project success and that within research model of primary human factors, Competences and Team composition have the most important influence on project success, which confirms set hypothesis. Findings thus coincide with results of the other researchers and it offers an overview of CSFs from different perspective and a new possibility to control complexly composed CSFs. This master thesis therefore aims to improve understanding of Primary human factors that affect ERP implementation success and is showing the way to human-centred model of ERP implementations
Light effects on beech saplings architecture in silver fir - beech forests
Get PDFZ namenom, da bi raziskali domnevni negativni vpliv zastiranja krošenj na razrast ter kakovost bukovih osebkov v razvojni fazi gošce, smo v GGO Novo mesto v GE Soteska na rastišcih Lamio orvale-Fagetum izlocili 60 ploskev treh velikosti vrzeli ter v vsaki analizirali 200 osebkov. Gošca je bila nenegovana. Na vsaki ploskvi smo ugotavljali naslednje kazalnike: gostota dreves, gostota gornjega sloja ter relativno jakost sevanja (RJO). Pri vsakemuod 600 osebkov smo analizirali višino, premer, višinski prirastek ter ugotavljali kazalce kakovosti kot so širina krošnje v dveh smereh, število živih in mrtvih vej, odklon od vertikale, krivost, tip rasti. Razmere kažejo, da je zaradi malopovršinskega gospodarjenja malo dostopne svetlobe. Tako smo oblikovali dva razreda RJO. V razmerah polne osvetlitve (RJO 67-92 %) kakovostni znaki gošc v nasprotju s pricakovanjem niso bili izrazito negativni. Delež osebkov z enim terminalnim poganjkom je bil tu najvecji, vitkostno razmerje ugodno, prisotne pa so bile daljše krošnje. Pri podrobni analizi šibke jakosti svetlobe smo ploskve razdelili v tri RJO razrede vrednosti od 0-29 %. V takšnih razmerah se je, v primerjavi z razmerami polne osvetlitve, pojavilo najvec dvovrhatih osebkov. V RJO razredu 0-9 % je bil delež takšnih osebkov nekoliko manjši. Ugodno je bila izražena plošcina krošenj ter dolžina cistega debla. Silaška rast je bila najmanj izrazita. Negativne lastnosti pri šibki osvetljenosti so se pokazale predvsem pri krivosti ter odklonu od navpicne rasti, višinski prirastki so bili nižji, vitkostno razmerje je bilo višje.Z namenom, da bi raziskali domnevni negativni vpliv zastiranja krošenj na razrast ter kakovost bukovih osebkov v razvojni fazi gošce, smo v GGO Novo mesto v GE Soteska na rastišcih Lamio orvale-Fagetum izlocili 60 ploskev treh velikosti vrzeli ter v vsaki analizirali 200 osebkov.
