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
Carbon storage and CO2 emission potentials of peat soils under forestes in Tyrol
No full textMoore sind einzigartige Ökosysteme, die besonders hinsichtlich der Archivfunktion, des Wasser- und Nährstoffhaushaltes, der historischen Nutzungsmöglichkeiten und der Funktion als Kohlenstoffsenke für die Wissenschaft, aber auch für die gesamte Bevölkerung von großem Interesse sind (vgl. Succow & Joosten 2001; Dierßen & Dierßen 2008). Grundsätzlich wird von Mooren immer dann gesprochen, wenn Torf gebildet wird oder oberflächlich ansteht (Succow & Joosten 2001, S. 2). 30 % des weltweiten Bodenkohlenstoffes sind in Mooren gespeichert, was diese Ökosysteme zu einem der effizientesten Kohlenstoffspeicherstätten macht (vgl. Drösler 2009, S. 60). Dies ist besonders bemerkenswert, ruft man sich vor Augen, dass lediglich 3 % der weltweiten Landoberflächen von Mooren eingenommen wird (Succow 2001, S. 2). Grünig (2010, S. 5) und Niedermair et al. (2011, S. 13) gehen davon aus, dass in Österreich ca. 90 % der ursprünglichen Moorflächen entwässert und primär für landwirtschaftliche Zwecke genutzt werden. Zusätzlich kann davon ausgegangen werden, dass zwei Drittel der noch naturnahen Moore mittlerweile auch gestört sind. In der Moorstrategie Österreich 2030+ werden Grundlagen, Ziele und Maßnahmen erklärt, welche helfen sollen diese sensiblen Ökosysteme besser schützen zu können. Des Weiteren wird angegeben, dass es unter anderem zu Mooren unter Wäldern wenig, bis keine Daten und Informationen hinsichtlich des Erhaltungszustandes und Kohlenstoffspeichervermögens gibt. Aus diesem Grund soll die vorliegende Arbeit versuchen, diese Fragestellungen für das Bundesland Tirol zu bearbeiten.There is no doubt, that reducing the current global warming is one of the greatest social challenges of this century. This task is incredibly hard to master and only reducing our CO2 emission is probably not enough. Therefore, it is essential that we must look after the world’s largest terrestrial carbon reservoir, the soil. In particular, the organic peat soil is a predominant factor in terms of storing huge amounts of carbon. As long as these carbon stores function under natural conditions, peat soil acts as a carbon sink. Due to inappropriate usage based on draining them for primary agriculture, these sinks can transform into greenhouse gas sources. About five percent of anthropogenic CO2 emissions worldwide are related to draining peat soils for agricultural usage. Only three percent of the worlds land surface is covered by peatland, which corresponds to about four million square kilometres. In Austria, the area covered by peatland for agricultural usage is relatively insignificant compared to other soils, but they can make up to 50 % of the agricultural CO2 emissions. In order to reduce anthropogenic greenhouse gas emissions, these peatlands must be rewetted if they were drained, or kept under natural conditions, to ensure the function of peatlands as carbon sinks. Unfortunately, there is very little information about such peat soils and especially about peat soils under forests. There is hardly any information at all. The existing studies mainly focus on natural peatlands or those under primarily agricultural usage. Therefore, there is also no reliable knowledge about the third dimension (thickness of peat soils) and their CO2 emission potentials.
With that in mind, the main research questions are:
i) Is there any information and data about peatland and peat soils under forests in Tyrol?
ii) How accurate are the existing datasets, compared to actual peatlands?
iii) How much potential peatland and peat soil is there under forests in Tyrol?
iv) How high is the carbon storage capacity and the CO2 emission potential of peatlands and peat soils in the first metre under forests in Tyrol?Simon Trixl, BSc.Summary in englischer SpracheMasterarbeit Universität Innsbruck 202
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
