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
A comparison of energy and environmental performance of passive and low-energy houses
Get PDFDie vorliegende Arbeit beschäftigt sich mit dem Vergleich von innenklimatischen Bedingungen in zwei energieeffizienten Mehrfamilienhäusern in Wien. Beide wurden gleichzeitig von denselben Gesellschaften am selben Grundstück errichtet und gleichen sich in Konstruktion und Grundrissen. Der Hauptunterschied zwischen den Gebäuden liegt (abgesehen von größeren Dämmstarken beim Passivhaus) im Lüftungssystem: Passivhäuser verwenden kontrollierte Lüftungssysteme während in Niedrigenergiehäusern der Luftaustausch hauptsächlich durch Fensterlüftung vonstatten geht. Wir haben innenklimatische Bedingungen (Lufttemperatur, relative Luftfeuchte und CO2) in jeweils zwei Einheiten jedes Gebäudes über einen Zeitraum von fünf Monaten gemessen. Die Ergebnisse wurden mittels Histogrammen, Psychrometrischen Diagrammen sowie PMV- und PPD-Berechnungen ausgewertet. Außerdem wurden die Gebäude hinsichtlich ihres Energieverbrauchs, der Kosten und der Wohnzufriedenheit der Bewohner verglichen. Beide Gebäude zeigen gute Ergebnisse, allerdings ist die Luftqualität, speziell in der kalten Zeit, im Passivhaus deutlich besser. Das Passivhaus verbraucht weniger Energie im Betrieb, kostet aber in der Erbauung um 4,7% mehr. Ein Lüftungssystem ist besonders für dichter belegte Wohnungen empfehlenswert.The present work compares apartments in two residential blocks in Vienna (one passive and the other one low-energy). These blocks were constructed simultaneously in the same location and with comparable building construction features and floor plans. The main difference between the two blocks (other than the higher degree of thermal insulation in the passive building) lies in the ventilation system:passive buildings deploy controlled ventilation, whereas the low-energy buildings rely mostly on user-operated natural (window) ventilation. We measured indoor environmental conditions (indoor air temperature, relative humidity, an
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
Ein Vergleich von Passiv- und Niedrigenergiegebäuden am Beispiel zweier Wohnhäuser in Österreich
No full textDie Bezeichnungen "Niedrigenergie"- und "Passiv"-Haus beschreiben verschiedene Grade der Energieeffizienz von Gebäuden im Zusammenhang mit Richtlinien und Standards unterschiedlicher europäischer Länder. In den letzten Jahren gab es viele Diskussionen über die Vor- und Nachteile von Niedrigenergie-, Passiv- und neuerdings auch Plusenergiehäusern. In diesem Kontext zeigt der vorliegende Beitrag eine detaillierte Bewertung von Wohnungseinheiten in zwei Wohnhäusern in Wien, Österreich. Eines dieser Gebäude ist ein Niedrigenergiehaus, während das andere die Kriterien eines Passivhauses erfüllt. Da beide Gebäude gleichzeitig von denselben Baufirmen am selben Grundstück errichtet wurden und sich in Konstruktion und Grundrissen gleichen, bieten sie ein geeignetes Beispiel für eine vergleichende Performance-Einschätzung: Der Hauptunterschied zwischen den Gebäuden liegt (abgesehen von stärkerer Dämmung des Passivhauses) im Lüftungssystem: Passivhäuser verwenden kontrollierte Lüftungssysteme, während in Niedrigenergiehäusern der Luftaustausch hauptsächlich durch Fensterlüftung vonstatten geht. Der Vergleich der Gebäude basiert auf gemessenen innenklimatischen Bedingungen (Lufttemperatur, relative Luftfeuchte und CO2-Konzentration) in jeweils zwei Einheiten jedes Gebäudes über einen Zeitraum von fünf Monaten aufgezeichnet. Außerdem wurden die Gebäude hinsichtlich Energieverbrauch (Heizung und Strom), grauer Energie für die Bauteile, CO2-Emissionen (sowohl für Bauteile als auch im Betrieb) und Konstruktionskosten verglichen.The terms "low-energy" and "passive" denote different levels of energy performance of buildings in the context of guidelines and standards in a number of European countries. In the last few years, there have been many discussions as to the benefits and drawbacks of low-energy and passive (and recently, energy-plus) buildings. In this context, the present contribution includes a detailed assessment of apartment units in two building blocks in Vienna, Austria. One of these blocks may be characterized as low-energy, while the other one adheres to the benchmarks for passive buildings. As these blocks have been erected on the same site and at the same time (with many similar construction and layout features), they provide a proper case in point for a comparative performance assessment: the main difference between the two blocks is, setting aside the higher insulation level of the passive building, the ventilation system. Apartments in the passive block use controlled ventilation, whereas the low-energy apartments use mainly window ventilation. The comparative assessment of these buildings was based on measured indoor parameters (indoor air temperature, relative humidity, and CO2 concentration) in two units of each block over a period of five months. Moreover, the apartments were assessed regarding actual energy use (heating, electricity), embodied energy for construction, CO2 emissions (both for construction and operation), and construction costs
A performance comparison of passive and low-energy buildings
No full textThe present paper compares apartments in two residential blocks in Vienna (one passive and
the other one low-energy). These blocks were constructed simultaneously in the same location
and with comparable building construction features and floor plans. The main difference
between the two blocks (other than the higher degree of thermal insulation in the passive
building) lies in the ventilation system: passive buildings deploy controlled ventilation,
whereas the low-energy buildings rely mostly on user-operated natural (window) ventilation.
We measured indoor environmental conditions (indoor air temperature, relative humidity, and
CO2 concentration) in two units of each block over a period of five months. Additionally, the
buildings were compared in view of energy performance and costs. The results suggest that
both buildings perform well. However, passive apartments turned out to perform slightly
better with respect to indoor environmental conditions. They also consume less energy during
operation time, but involve slightly higher initial (construction) costs
