Bolstering Family Control: Evidence from Loyalty Shares
We study the introduction of a new control-enhancing mechanism in Italy, a country still characterized by family-controlled firms but with increasing importance of institutional investors. Since 2014, Italian firms have been able to adopt loyalty shares, which allow a double voting right if shares are continuously held for at least two years. We find that about 20 percent of listed firms have introduced loyalty shares, and family-controlled firms are the most likely adopters. Loyalty shares neither anticipate acquisitions, nor equity issues by the adopting firm. Instead, they allow controlling shareholders to reduce their equity stake without losing control. We report no evidence of an adverse wealth effect both at the adoption and in the years following it. As expected, institutional investors vote against the introduction of loyalty shares. Yet, they do not reduce their holdings afterwards, as incremental governance costs are outweighed by the superior performance of adopting firms. Overall, our evidence suggests that bolstering family control is the main effect of the introduction of loyalty shares
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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

Haematological abnormalities in kidney tumours
The main haematological parameters, particularly haemoglobin concentration and the numbers of leukocytes and platelets, were studied in 146 kidney tumour patients. Only 119 of the subjects studied later underwent nephrectomy. In 66 patients the tumours were limited to within the renal capsule (group I) while in 39 other subjects the tumours had gone beyond this limit and had invaded the perirenal tissue (group II). 27 patients had metastasis at one or more sites (group III). In the remaining 14 subjects group IV) without proven metastasis, the surgical staging was not available, since because of cachexia they had not undergone nephrectomy. More frequent signs were: anaemia (Hb < 12 g/dl), mainly normochromic, found in a high percentage of cases (41% in group I, 59% in group II, 74% in group III, 79% in group IV) and leukocytosis (G.B. > 8000/mm3: 38% in group I, 51% in group II, 37% in group III, 50% in group IV). Mild thrombocytosis (P = 350,500 x 103/mm3) was found with notable frequency mainly in groups II and groups III (20% and 18%, respectively). On the other hand leukopenia (G.B. < 3500 per mm3) and thrombocytopenia (P < 140 x 103 per mm3) were rather rare. The results of our study are also discussed in relation to the main findings in the literature
