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
Solarstrahlung und Tageslicht
No full textDas Buch erläutert praxisnah die physikalischen, energetischen, meteorologischen und lichttechnischen Grundlagen der Solarstrahlung und des Tageslichts. Es ist Grundlage für die Bestimmung effektiver Wirkungen der Solarstrahlung in Gebäudetechnik und Gesundheit. Der Solarstrahlung kommt für das Leben auf der Erde die größte Bedeutung zu. Dieses Thema wird in diesem Buch aufgegriffen. Nach einer Beschreibung des Prozesses der Strahlungserzeugung und des Durchganges der Solarstrahlung durch die Erdatmosphäre werden die Wechselwirkungen durch physikalische, chemische, biologische und medizinische Effekte beschrieben. Da über verschiedene Formen der Sonnenenergiewandlung bereits eine kompetente Fachliteratur vorliegt, wird hier auf die entsprechenden Ausführungen verzichtet. Dagegen wird auf die Wirkungen über das menschliche Auge - also auf das Tageslicht - besonders eingegangen. Tageslicht als passive Solarstrahlungstechnik dient nicht nur der Beleuchtung von Innenräumen der Gebäude, es kann auch einen merklichen Anteil der Energieeinsparung liefern. Der Jahresumsatz der Energie eines Gebäudes hängt von den verwendeten wärmetechnischen Installationen, den architektonischen Gegebenheiten und der Kunstlichttechnik ab. So werden technische Lösungen sowie Komponenten beispielhaft zusammengestellt und Berechnungsverfahren und technische Regel angegeben. Besonderer Augenmerk wird auf eine qualifizierte, integrale Gebäudeplanung gelegt, die auf den Bedürfnissen der Nutzer basiert und somit nicht nur die energetische Gesamtbilanz verbessert, sondern gleichzeitig die Aufenthaltsqualität erhöht. Dieses Buch führt in die notwendigen physikalischen und meteorologischen Zusammenhänge von Solarstrahlung und Tageslicht ein, indem die doppelt spektralen Zusammenhänge von Strahlung und Effekt, wie die lichttechnischen und strahlungsphysikalischen Kennzahlen und die gesundheitlichen Wirkungen erläutert werden. Das Buch erläutert zudem Verfahren zur Bestimmung des Energieumsatzes mit Planungstools. Das Buch ist für Architekten, Bauingenieure, Gebäudetechniker, Lichttechniker, Arbeitsmediziner, Meteorologen und Umwelttechniker in Planungspraxis, Industrie, Forschung und Lehre geeignet
Ergonomics and design for all : an IEA international round table
No full textA round table discussion on Ergonomics and Design for All took place during aninternational meeting on ergonomics organized by the Dutch organization “Human Factors vereniging” in Amersfoort, NL in November 2016. This event was co-hosted by FEES-Federation of European Ergonomics Societies and CREE-Centre for Registration of European Ergonomists. The round table discussion consisted of various expert talks on different aspects of the Design for All concept ranging from applications in the built environment to the health care sector. The goal was to introduce the concept, provide an overview of European mandates and subsequent standardization approaches as well as delivering particular insights from research institutions. Both the speakers panel and the audience consisted of individuals from various countries. The international participation and the active discussion during the round table have shown that the work of the IEA TC Ergonomics in Design for All is seen as an important and valuable activity. The IEA international round table was a huge success. There is broad support for the aim of the TC to establish “Design for All” as a generally accepted and applied methodology in the process of designing for products, services and processes
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
