Aymo Brunetti im Geldcast (PODCAST-Interview von Fabio Canetg)
No full text«Die Inflation wird uns wohl noch lange beschäftigen», sagt Aymo Brunetti, Wirtschaftsprofessor an der Universität Bern und ehemaliger Chefökonom der Bundesverwaltung. Im neusten Geldcast erklärt er, wie er zu dieser Einschätzung kommt und wieso es nach dem Rekordverlust der Nationalbank der falsche Zeitpunkt sei, um über Gewinnausschüttungen zu diskutieren. Zudem sprechen wir im Geldcast über seine Lehrtätigkeit an der Universität Bern. Er sagt: «Meinungen von Fakten zu trennen, ist in unserem Fach nicht immer einfach – im Unterricht aber essentiell.» Zuletzt haben ihn einzelne Studierenden aufgefordert, auch über alternative Wirtschaftstheorien zu sprechen, etwa über feministische Ökonomie und marxistische Theorien. Warum er das nicht so einfach findet, und weshalb er die Mainstream-Ökonomie nach wie vor schätzt: Das und mehr erfahren Sie im neusten Geldcast
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
Germline mutations of the BRICA1-associated ring domain (BARD1) gene in breast and breast/ovarian families negative for BRCA1 and BRCA2 alterations
No full textBARD1 (BRCA1-associated RING domain) was identified by yeast two-hybrid screening as a protein interacting with BRCA1. Somatic and germline mutations of BARD1 have been detected in sporadic breast, ovarian, and endometrial cancers. The present study represents the first description of BARD1 germline mutations in hereditary breast and breast/ovarian cancer patients. We analyzed the BARD1 gene in 40 families with hereditary breast and breast/ovarian cancer, tested negative for BRCA1 and BRCA2 mutations. A mutational analysis by PCR-SSCP on the coding region and the exon-intron splice boundaries of the BARD1 gene yielded four different germline mutations. A group of 20 patients diagnosed with sporadic breast cancer below the age of 40 was also examined and only one germline mutation was found. A study of loss of heterozygosity at the BARD1 locus in neoplastic tissues from patients with BARD1 germline mutations was carried out. In all cases, we were unable to find any evidence for allelic deletions. The involvement of BARD1 mutations in the susceptibility to hereditary breast and breast/ovarian cancer is discussed.

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
Aymo Brunetti im Interview zum Thema Cocos (ECO-Beitrag von Reto Lipp)
No full textSchweizer Grossbanken sollen mit Pflicht-Wandelanleihen ihr Eigenkapital erhöhen, um krisensicher zu werden. Diese neuen «Too big to fail-Kapitalanforderungen» haben Bundesrat, Finma und SNB letzte Woche vorgestellt. Doch namhafte Ökonomen kritisieren, diese Instrumente seien heikel. Aymo Brunetti widerspricht. Der Wirtschaftsprofessor von der Universität Bern war bis Ende 2014 Leiter einer vom Bundesrat eingesetzten Expertengruppe zur Weiterentwicklung der Schweizer Finanzmarktstrategie

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
