- Det er viktig at vi kaster kritiske blikk på det vi gjør
No full textSenterleder Lars Mehlum ved NSSF mener at Bob Goldney stiller viktige spørsmål. Men han tror ikke at selvmordsøkningen i et land som USA skyldes mer åpenhet
Sikkerhetsplan – en metode med selvmordsforebyggende effekt
No full textI følge nyere studier har en sikkerhetsplan selvmordsforebyggende effekt. Den anbefales fremfor generelle kriseplaner og ikke-selvmordkontrakter, og utarbeides i samarbeid mellom behandler og pasient. Her forklarer Lars Mehlum, leder av NSSF, hvordan
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
Chain of care for patients with intentional self-harm: an effective strategy to reduce suicide rates?
No full textChain of care for patients with intentional self-harm was important in the Norwegian national action plan to prevent suicide. In this study there were two aims: (1) to calculate the potential effects of chain of care on reducing suicide rates, and (2) to assess whether suicide rates decreased more in areas where chain of care had been implemented than in other areas. We observed no differences in changes in suicide rates between areas with and without the intervention. The calculated potential effects of chain of care on national suicide rates were very small, even under unrealistically favorable conditions.NORSK SAMMENDRAG: Er behandlingskjede for pasienter med villet egenskade en effektiv strategi for å redusere selvmordsratene?\ud
\ud
Det å etablere en behandlingskjede for pasienter innlagt i sykehus etter selvmordsforsøk eller annen villet egenskade har vært en viktig strategi i den norske handlingsplanen for forebygging av selvmord. En behandlingskjede innebærer at pasienten følges opp av en eller flere behandlingsinstanser i inntil ett år etter sykehusoppholdet.\ud
\ud
Individrettet strategi\ud
Studien gir ingen belegg for at en slik individrettet risikostrategi er effektiv for å redusere selvmordsratene i befolkningen. SIRUS-forsker Ingeborg Rossow står sammen med Lars Mehlum, Finn Gjertsen og Bjørn Møller bak studien, som er publisert i tidsskriftet Suicide and Life-Threatening Behavior.\ud

Om studien\ud
Forskerne har beregnet hvor stor den potensielle effekten av behandlingskjeder vil kunne være under ulike betingelser, og sammenliknet endringer i selvmordsrater i befolkningen i områder som har og ikke har innført behandlingskjede.\ud
\ud
Liten effekt\ud
Beregningene av potensielle effekter viste at selv under urealistisk gunstige betingelser ville den forventete effekten på selvmordsrater være veldig liten. I tråd med dette viste også sammenlikningene av observerte selvmordsrater over tid at det ikke var noen forskjeller i endringene i selvmordsrater i områder som har og ikke har innført behandlingskjede
Den fastlåste sorgen- komplisert sorg
No full textBehandling av komplisert sorg (Complicated Grief Treatment, CGT) er en manual- og evidensbasert behandling utviklet av Dr. Katherine Shear, professor i psykiatri ved ColumbiaUniversity i New York. Komplisert sorg forekommer hosom lag syv prosent av alle som opplever tap av nærstående.Det er betydelig høyere forekomst hos foreldre som har mistet barn, samt ved plutselig og voldsom død.

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
