Il ruolo della partecipazione nella didattica universitaria
Il contributo riflette sulla didattica universitaria e individua alcuni dispostivi che possono attivare percorsi partecipativi tali da favorire la professionalizzazione. Tra tali dispositivi, l’uso di pratiche vicarianti, la discussione tra pari sia in presenza che on line di tematiche connesse ai vissuti personali, un maggiore rapporto tra didattica e ricerca, percorsi di alternanza scuola-lavoro. Si presenta infine una ricerca in cui sono stati sperimentati tali dispositivi. Emerge che non la pratica in quanto tale, ma una rilettura di vissuti diretti e indiretti attraverso la lente della propria storia favorisce un partecipazione attiva ai processi di formazione e un’assegnazione di senso alle conoscenze acquisite

Psychological distress resulting from a mosaic of psycho-social variables as a risk factor for acute coronary syndromes
[Psychological stress as precipitating factor of the acute manifestations of ischemic cardiopathy].
Psychological stress may play an important role as a risk factor for coronary heart disease (CHD). Psychological stress consists of different components whose diverse role in the onset of the acute manifestations of CHD is still not clear. We studied 80 patients with acute CHD (56 with unheralded myocardial infarction, 24 with unstable angina, mean age 55 +/- 9 years, 55 men) vs 80 controls (mean age 50 +/- 9 years, 52 men) admitted for an acute traumatic event. We proposed to both groups these questionnaires: a retrospective self and etero-evaluation of the degree of psychological stress; the modified Maastricht questionnaire (MMQ) that evaluates psychic and physical manifestations of psychological stress in the period preceding admission; the social support questionnaire (SSQ); the life event assessment that evaluates frequency and importance of life events in the year preceding admission. Psychological stress index was greater in patients (self-evaluation = 7.1 +/- 2.4; etero-evaluation = 7.4 +/- 2.3; MMQ = 91 +/- 30.8) than controls (self-evaluation = 4.3 +/- 2.3; etero-evaluation = 4.3 +/- 2.4; MMQ = 58.6 +/- 32.5; p < 0.001 for all questionnaires). The perception of strong social isolation was greater in patients (SSQ = 29.8 +/- 11.8) than controls (SSQ = 23.8 +/- 9.6; p < 0.001). Painful life events were more numerous in patients (10.7 +/- 2.3) than controls (8.2 +/- 3.4; p < 0.05) and perceived in a more negative way (patients = 12.7 +/- 4.1 vs controls = 10.2 +/- 3.8; p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS
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
