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
C.R.I.G.A. - Catasto Ragionato Informatico delle Grotte Archeologiche
No full textIl Progetto C.R.I.G.A. - Catasto Ragionato Informatico delle Grotte Archeologiche è un Progetto dell'Università degli Studi di Trieste, coordinato da E. Montagnari e F. Cucchi e realizzato con la collaborazione di giovani ricercatori.
Il risultato tangibile del Progetto è un archivio informatico georiferito – denominato appunto C.R.I.G.A. – che contiene i dati storico-archeologici e geo-ambientali di 179 cavità, su un totale di 2729 grotte naturali catastate.
Il C.R.I.G.A. è nato come strumento di ricerca – obiettivo ultimo è, infatti, l’identificazione degli elementi del paesaggio fisico che potrebbero aver influito/condizionato l’uso di ciascun sito da parte dell’uomo in antico –, ma si sta rivelando anche strumento utile di conservazione, tutela e valorizzazione di un patrimonio naturale e culturale di grande valore. Dati finalizzati al rilevamento dello stato di conservazione e delle potenzialità in termini di fruizione didattico / divulgativa e turistica sono già stati inseriti all’interno del database.
Il database è da giugno 2011 visibile in web all’indirizzo www.units.it/criga a seguito della conversione dell’originaria banca dati, creata in Microsoft Access e successivamente esportata in mySQL
Nutritional status and oxidative stress in an elderly Sardinian population
No full textWeight loss and overweight/obesity – frequent
consequences of malnutrition – may impair functional status
and worsen concomitant morbidities in the elderly,
often through changes in oxidative balance. In order to
verify the relationships between these factors, a group of elderly people living on the island of Sardinia (Italy)
underwent health and nutritional status assessment and oxidative balance evaluation. The elderly subjects had significantly
higher d-ROMs test and body mass index (BMI) values than controls (d-ROMs 325.4 ± 66.3 vs. 295.4 ± 58.9 CARR U, p = 0.006; BMI 28.0 ± 4.6 vs. 21.7 ± 1.4 kg/m2, p < 0.0001). The risk of malnutrition in the elderly
subjects was evaluated with the Mini Nutritional
Assessment (MNA), which showed that 32 of the 111 elderly subjects (28.8%) were at risk of malnutrition, of
whom 11 (34%) were overweight and 10 (31.2%) obese. Oxidative stress was negatively and significantly correlated with nutritional status. Oxidative stress may precede malnutrition, even in the absence of weight loss. Routine evaluation of nutritional status and oxidative balance in
the elderly may help identify an early risk of malnutrition
so that treatment can be personalized
Laboratorio di Mondialità: the approach of italian medical students to global health issues
No full textWidespread interest in Global Health issues is a common feature of Medical Schools over the last decade, nevertheless surveys suggest that in-depth teaching of Global Health issues in italian medical faculties are rare. Six years ago, the members of Segretariato Italiano Studenti in Medicina (SISM) started to deal with global health issues and, in order to fill this gap, created a national three days workshop called Laboratorio di Mondialità (LabMond).
Since 2007, every year, SISM, in collaboration with the Centre for International Health (CSI) and the Italian Global Health watch (OISG), organizes LabMond for about one hundred italian medical students.
The event is set up as a workshop, consisting in an introductional part, analysis and feedback sessions.
The main topics of LabMond consist in determinants of health, health inequalities, migrants medicine and how globalization influences our health; these topics are faced with interactive methodologies such as case studies, small working groups, role plays.Small working groups, about ten people each, are moments in which students work, figure out common ideas about global health and migrant medicine, develop concret strategy to bring at home the talked-about issues and carry them on.
More generally, the organizational choice of a laboratory, rather than a course or a conference, aims to call into question the position of participants, and the term "Laboratorio" underlines the importance of the student's work on his knowledge and our attempt to stimulate his curiosity to go deep into the subject.
Thus, LabMond is more than a simple course on Global Health: it represents an educational opportunity for the participants as well as for the organizers and the trainers.
In the last six years hundreds of students has been sensitized and in more than ten different italian Faculties of Medicine these students, with the help of global health experts, set up local courses and local group of self-education to go deeper in these topics.
The students of SISM believe that it's necessary to continue to support this process in which such a lot of students are involved in order to foster an ethic re-placement of students themselves as future health professionists and as characters able to reduce health inequalities and injustices that nowadays are killing people on a large scale
