Visibilità e invisibilità. Posizionamento, fiducia e accesso al campo in un’etnografia sui migranti romeni in Italia
No full textThis paper discusses researchers’ positionality in multi-sided ethnography of migration. It argues that insider researchers may use multiple strategies to access the field: they may also have different visible and invisible positions. Access to the field may greatly vary in respect to these positions, time available, and the research location - at home or abroad. The research was conducted with a group of Romanian irregular migrants in Milan, by a Romanian researcher. The researcher had multiple roles: invisible migrant, migrant sociologist, friend of a friend and friend of a relative. While visible strategies in Milan posed serious limitations to accessing the field, invisible ones were more successful. Besides, the use of trust relations through gatekeepers, here friends and relatives, were the most successful strategies. Time and space played also an important role during the fieldwork. Abroad migrants had not had enough time at disposal in contrast to the situation at home during their summer vacations. Location was even more important. Abroad irregular migrants tended to be untrustworthy. In contrast to the situation at home, where they were open to research inquiries
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
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
Milano Centrale. Status ilegal, piețe de muncă și practici transnaționale la migranții români din Milano: Milano Centrale. Illegal status, labor force markets and transnational practices of Romanian migrants in Milano
No full textThis study is an analysis of a group of Romanian migrants in Milan and of their transnational practices between Milan and their hometown in Romania. The analysis focuses, on the one hand, on the structure of the environment of the Romanian migrants in Milan (both legal and illegal migrants) and, on the other hand, it relates the transnational practices of the Romanian transmigrants (remittances, flows, circulation) to the main opportunities and risks migrants face. Though very dynamic, these transnational practices are to be seen rather in a less institutionalized and individualized field of social practices between Romanian and Italian localities; besides, in order to better understand these emergent transnational dynamics, the focus of the research is on the local contexts in both countries. In this article I try to demonstrate that the very strong dynamism of the transnational practices of the Romanian migrants is related at least in its incipient phase, to the insecure and speculative character of the migrant environment. Their development is yet unclear
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
