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
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

Brannsikkerhet og trebyggeri
Full text linkDenne oppgaven er en litteraturstudie hvor formålet er å identifisere hvordan gjeldende brannsikkerhetsregelverk i Norge påvirker mulighetene for økt bruk av tre i høye bygninger, og sammenligne det norske brannsikkerhetsregelverket med brannsikkerhetsregelverkene i Sverige, Østerrike og England.
Studien tar for seg følgende problemstilling: «Hvordan påvirker dagens regelverk for brannsikkerhet mulighetene for å bygge med tre i Norge, og hvilke forskjeller finnes sammenlignet med andre relevante europeiske land?». For å besvare problemstillingen på en systematisk og omfattende måte, ble tre veiledende spørsmål benyttet: 1) Hva er de gjeldene brannsikkerhetsregelverkene for trebyggeri i Norge og andre relevante europeiske land, og hvilke forskjeller finnes her? 2) Hvilke barrierer og utfordringer oppstår i norsk trebyggeri som følge av brannsikkerhetsregelverk? 3) Hva er mulige løsninger på utfordringer knyttet til brannsikkerhetsregelverk, som kan bidra til økt bruk av tre? Studien er en kvalitativ litteraturstudie, og er basert på en omfattende gjennomgang av nasjonale og internasjonale brannsikkerhetsregelverk, med fokus på nøkkelområder som bæreevne, branncelleinndeling og materialkrav.
Funn fra studien viser at Norge stiller strenge krav til bruk av ubrennbare materialer i bærende konstruksjoner og fasader i brannklasse 3 og 4. Dette begrenser mulighetene for bruk av tre, som klassifiseres som et brennbart materiale. I kontrast tillater Sverige og Østerrike bruk av tre gjennom kompenserende tiltak som sprinkling, brannimpregnering og brannsikker kledning. I tillegg utgjør kravet om at bærende konstruksjoner i Norge må kunne motstå et fullstendig brannforløp, inkludert avkjølingsfasen, en betydelig barriere, noe som ikke er spesifikt angitt i de andre analyserte landenes regelverk. Basert på denne studien kan det konkluderes med at selv om kompenserende tiltak gir mulighet for bruk av tre i høye bygg, utgjør de strenge kravene til ubrennbare materialer i Norge fortsatt en stor hindring. Å adoptere noen av tilnærmingene som praktiseres i Sverige og Østerrikes regelverk, kan bidra til økt bruk av tre i høye bygninger i Norge uten å redusere brannsikkerheten.This bachelor thesis is a literature study where the purpose is to identify how the present fire regulations in Norway impact the possibilities for increased use of timber in tall buildings and comparing these regulations to the fire safety regulations in Sweden, Austria and England.
The study addresses the following issue: “How does today’s fire safety regulation affect the possibilities of building with timber in Norway, and what differences exist compared to other relevant European countries? ». To address this issue in a systematic and comprehensive manner, three guiding questions were used: 1) What are the applicable fire safety regulations for wooden buildings in Norway and other relevant European countries, and what differences exist here? 2) What barriers and challenges arise in Norwegian timber construction because of fire safety regulations? 3) What are possible solutions to challenges related to fire safety regulations that can contribute to increased use of timber? The method used is a qualitative literature study. The study is based on comprehensive review of national and international fire safety regulations, where the focus is on key areas such as loadbearing capacity, fire compartment division, and material requirements.
Throughout this study, findings indicate that Norway imposes strict requirements for non-combustible materials in load-bearing structures and facades in fire class 3 and 4. This limits opportunity for the use timber, which classifies as a combustible material. In contrast, Sweden and Austria permit the use of timber through compensatory measures, such as sprinkling, fire impregnation and fire-resistant cladding. In addition, does the demand that load-bearing structures must be able to withstand a complete fire course, including the cooling phase in Norway present a significant barrier, which is not specifically stated in the other countries’ regulations. Based on this study, it can be concluded that while compensatory measures provide an opportunity to use timber in high buildings, does the strict non-combustibility requirements in Norway remain as a major obstacle. Adopting some of the regulatory approaches seen in specifically Sweden and Austria, can contribute to increased timber use in high buildings in Norway, without reducing the fire safety

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
