Comunita' minori in ambiti svantaggiati: verso una visione globale attraverso analisi locali in differenti contesti europei
No full textLa promozione di un sviluppo sostenibile di comunità minori in ambiti svantaggiati può trarre giovamento dalla condivisione della conoscenza di esperienze in realtà analoghe. Ciò rende utile individuare processi metodologici che permettano di confrontare realtà anche molto lontane geograficamente, e non solo, ma che hanno in comune alcune caratteristiche territoriali, sociali, economiche, ed alcune dinamiche in atto, prima fra tutte il pericolo di scomparire a causa del forte decremento di popolazione, col rischio che vadano persi valori storici e culturali, o che non vengano valorizzate potenzialità, quali quelle paesaggistiche, ambientali o turistiche, con la finalità ultima di individuare “buone pratiche” di governo del territorio trasferibili al altri contesti territoriali

No full textDietary habits during the COVID-19 pandemic. Are work environments part of the problem?
No full textThe COVID-19 pandemic pushed a large number of workers out of their offices and to their homes for a significant period of time for teleworking. However, some workers continued to work in their offices and others went home only partially. This arguably exogenous shock to the way in which workers performed their jobs opened the opportunity to evaluate whether work environments are ideal for promoting healthier diets and reducing overweight among office workers. We explore the results of two consecutive surveys (pre- and during-COVID-19) to examine whether workers working from home perceived their situation as more favorable in terms of healthy eating habits and weight gains. Our results show that workers did perceive their homes as places where they can follow healthier eating habits, but this was not accompanied by weight loss. On the contrary, workers fully teleworking were more likely to perceive weight gains and diet-related health problems than their in-office counterparts. Among teleworkers, those only partially teleworking were the most affected. This study opens many questions about food environments at work that remain unanswered. More studies in this area are needed to understand how the food at work affects the worker's health
Non-O blood group and outcomes of in vitro fertilization.
No full textPURPOSE
Retrospective and cross-sectional studies suggested that non-O blood group may be associated with failures of in vitro fertilization (IVF), but data remain controversial. The aim of this observational cohort study was to prospectively evaluate the effect of non-O blood type on clinical outcomes of IVF.
METHODS
Women < 40 years who underwent IVF and had ABO blood type recorded as part of the routine workup were eligible. The primary study outcome was live birth. Secondary outcomes included spontaneous abortion, positive pregnancy test, and clinical pregnancy.
RESULTS
A total of 497 women with a mean age of 34.6 (standard deviation 3.2) years were included. The mean number of embryos transferred was 2.3 (standard deviation 0.6). The most common ABO blood types were O (n = 213, 42.9%) and A (n = 203, 40.8%), while 63 (12.7%) and 18 (3.6%) women had the B and AB blood types, respectively. Differences in live birth (21.8 vs. 24.3%, odds ratio [OR] 1.17; 95% confidence intervals [CI], 0.76 to 1.78), positive pregnancy test (37.9 vs. 36.6%, OR 0.96; 95% CI, 0.66 to 1.38), clinical pregnancy (35.1 vs. 33.8%, OR 0.95; 95% CI, 0.66 to 1.39), and spontaneous abortion (12.3 vs. 9.2%, OR 0.72; 95% CI, 0.41 to 1.29) between women with O and non-O blood type were not statistically significant.
CONCLUSIONS
In a prospective cohort study, we confirmed the lack of a significant association between non-O blood type and clinical outcomes of IVF. Further studies are needed to clarify whether non-O blood group has any prognostic relevance in women undergoing IVF
Variations on the Author
No full text“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
