Community control of hypertension at the worksite in a metallurgical factory: results of 1-year follow-up
No full textThis study was designed to assess advantages and cost-effectiveness of community control of hypertension at the worksite in a metallurgical factory in Pavia. Under consent of managers and trade-unionists, a screening program was undertaken. 2701 subjects (95% of the total number of employees) were screened: 277 (10.2%) were hypertensive, 101 (38%) did not know to be hypertensive, 56 (22%) knew to be hypertensive but they were untreated and only 20 (8%) of those under treatment were adequately treated. Of the 277 essential hypertensives, 262 (94%) adhered to the program. They were assigned to beta-blocking or diuretic treatment following WHO rules. Then an aggressive follow-up was started (the hypertensives were periodically called to control at the worksite). 257 (98%) were participants 1 year later. Our worksite hypertension control program allowed us to identify many cases of undiagnosed or untreated hypertension and to start an early treatment. One year after entry, the percentage of hypertensives achieving a normal blood pressure (85%) was almost twice as that obtained by conventional clinical approach employing the same type of treatment. Besides, more than 95% of hypertensives remained under control at 1 year. Regarding the costs, it is difficult to generalize, but our study suggests that, if there is the will, it is possible to realize programs of hypertension community control at a very low cost (in our experience: 43 dollars per hypertensive per year

Università e pubblica amministrazione per una Ricerca mirata
No full textÈ risaputo che la capacità competitiva di un paese (capacità di produrre in-novazione, sviluppo tecnologico, brevetti e cultura) e dunque la creazione di ricchezza, assicurando benessere, “dipende dalla sua capacità di investire nell’istruzione, nell’università e nella ricerca” (Maccacaro, 2007).
È parere altrettanto condiviso che il nostro paese negli ultimi anni, non avendo investito in modo deciso in questa direzione, ha ridotto drasticamente il finanziamento destinato alla ricerca scientifica.
A questo aggiungiamo una significativa riduzione della capacità di spesa della Pubblica Amministrazione, committente storico e fondamentale per la produzione di ricerca scientifica sviluppata dall’Università italiana.
Un contesto certamente critico che ha determinato una progressiva riduzione delle occasioni di cooperazione in ricerca tra Pubblica Amministrazione e Università, e che obbliga a interrogarci da una parte sull’evoluzione di questo scenario, dall’altra sulla prefigurazione di programmi e azioni che saremo chiamati ad attuare.
Per fare chiarezza e favorire un processo di riflessione, il saggio pone tre quesiti a cui cerca di rispondere. “Quale ricerca scientifica?” con l’obiettivo di chiarire le diverse tipologie di ricerca, di finanziamento e di modelli contrattua-li. “Una ricerca scientifica per chi e per cosa?” con l’obiettivo di identificare la committenza, definire la Pubblica Amministrazione e illustrare le ragioni del rapporto tra questa e l’Università. Infine, “Quali scelte da operare?” con l’obiettivo di proporre azioni e priorità per una collaborazione efficace tra Pub-blica Amministrazione e Università
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
