The Role of family in suicide rate in Italy
Get PDFWe use national panel data at provincial level to investigate the relationship between suicide rates and socio-economic factors in Italy. The role of family, drug and alcohol consumption, social conformism and population density are the main factors in explaining the suicide rate in Italy. In a further step, we check for the differences
in the suicide determinants between southern and northern provinces. The findings show that the number and size of families as well as alcohol or drug abuse play a key
role in the northern provinces, while density and social conformism appear to be the main factors in the South

IPRs and international knowledge flows: Evidence from six large emerging countries
Get PDFThis paper studies international knowledge flows looking at: (i) patent citations that track codified knowledge and (ii) technological collaborations between inventors that gauge knowledge transmitted through face to face contacts. It uses a gravity model for 13 countries (Brazil, Russian Federation, India, China, South Africa, Mexico, the USA, the UK, Japan, Italy, Germany, France and Canada) using EPO data. In the case of tacit knowledge flows it shows that intellectual property rights (IPRs) reinforcement has no effect and that sharing a common legal origin and technological proximity are more important than geographical distance. In the case of codified knowledge flows IPRs reinforcement has a positive effect only when applicants' citations are considered
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
Academic patent value and knowledge transfer in the UK. Does patent ownership matter?
Get PDFThis paper deals with an issue which is particularly relevant in the literature on IPR and university-industry knowledge transfer: is the ownership structure of academic inventions relevant for patent quality and the efficiency of the knowledge transfer process? This question is also particularly signi�cant in Europe where some countries have followed the Bayh-Dole Act example to increase the involvement level of universities in IP management. The paper uses a novel dataset of academic inventors in the UK, which includes university patents (i.e. patents owned by universities) and corporate patents (i.e. patents signed by academic scientists but owned by private companies) in the period 1990-2001. The UK is an interesting case to study due to the tradition of university involvement in IP management as it was one of the fi�rst countries to implement the university ownership model.
The main results may be summarised as follows.
(1) Controlling for observable patent and scientist characteristics, corporate patents received more citations than university patents in the �first three years after fi�ling, but (2) this difference is less signi�cant when considering a longer time window. However, (3) there is no knowledge fertilisation across public (university) and private institutions: university patents mainly cite other university patents and the same reasoning applies to corporate patents. Moreover (4) knowledge fl�ows from university patents are even more geographically localised than those from corporate patents. Finally, (5) among scientists� characteristics, professor�'s scientifi�c quality and his patenting experience seem to be correlated with patent value.
From a policy prospective, the results in points (1), (2) and (3) cast some doubts on the role of university ownership as an instrument to foster and facilitate knowledge transfer between academia and industry and raise serious questions about the effect of policies towards increasing the role of technology transfer offices in managing academic patents
