Determinants of foreign workers' wages in two Italian regions with high illegal immigration
No full textSince the end of the 1970s Italy has moved from being an out-migration country to being a foreign immigration country, but very few studies have addressed the factors determining the wages of immigrant workers, owing to the lack of available data. In this paper we analyse the determinants of the wages of immigrants in some areas of Latium and Campania, where the share of illegal immigration is relatively high, using the results of a set of sample surveys which collected information on several aspects of the immigration process in the years 1993-94. The purpose of the article is to shed some light on the factors underlying wage distribution among the immigrants using an estimation method that controls for sample selection problems. According to the empirical results, income differences seem to be relatively high among immigrants. Differences in labour market integration among sexes and area of origin clearly emerge from the results. Moreover, legal status plays an important role in the explanation of the wage gap between documented and undocumented immigrants, also because of the different occupational sector structure in the two groups. © Fondazione Giacomo Brodolini and Blackwell Publishers Ltd 1999
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
Tailored versus standard dose prophylaxis in children with hemophilia A.
No full textProphylaxis is universally recognized as the treatment of choice in people with hemophilia, and tailored prophylaxis is the consistent modification of the standard weight-based dosing regimen. A large number of factors guide the choice of a specific tailored regimen, and different regimens are under evaluation. Tailored low-dose frequent regimens are likely to be cost-effective, but they are less accepted by patients. Escalating dose regimens seem to be quite effective in preventing bleedings and, consequently, arthropathy, although data on long-term outcomes are still not available. Pharmacokinetic-driven approaches have been also proposed. Sensitive and validated tools able to reliably measure the different outcomes are necessary in this setting. With regard to the evaluation of arthropathy, magnetic resonance imaging and ultrasound are promising imaging techniques in detecting early joint damage. Factor VIII trough levels can be considered a measure of the efficacy of FVIII infused, although other factors influence the bleeding pattern. Global assays of coagulation could provide more complete information on the hemostatic potential of a sample and predict bleeding phenotype. These techniques are also promising for the individualization of prophylaxis regimens, potentially resulting in less frequent dosing, more comfortable and less expensive approaches
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
