    L’introduzione delle Nuove Tecnologie dell'Informazione e della Comunicazione (NTIC) nelle pratiche di insegnamento e apprendimento coinvolge tutti gli ordini di scuola. Il panorama applicativo qui delineato rimanda ad un uso esclusivamente documentaristico della rete, in realtà le tecnologie offrono alla geografia una policromia di applicazioni che vanno dalla costruzione di nuova conoscenza, alla creazione di ambienti per la collaborazione e per la partecipazione fino allo sviluppo di prodotti ipermediali che, riportati on-line, possono dare una rappresentazione del territorio secondo una nuova scalarità più collegata all’uso dei sensi in grado di sviluppare sguardi tridimensionali. Le testimonianze riportate in questa sessione didattica dimostrano infatti che tra la geografia e Internet vi sono numerosi punti di convergenza che caratterizzano da un lato alcuni concetti disciplinari, come quelli di nodo e rete, dall'altro la struttura stessa di Internet e le sue interazioni transcalari con i luoghi materiali (ad esempio attraverso i siti della Pubblica Amministrazione). Nell’ambito della geografia della comunicazione, in particolare, si è rilevato lo stretto legame tra telecomunicazioni, distanze e identità, per cui lo studio dei luoghi telematici sembra essere fondamentale per descrivere le relazioni fra la società umana e i luoghi sia a livello di gerarchie spaziali sia a livello di sense of place

    Sexual Dysfunction at the Onset of Type 2 Diabetes: The Interplay of Depression, Hormonal and Cardiovascular Factors

    Introduction. Several data have emphasized the importance of early diagnosis of erectile dysfunction (ED) and meticulous cardiovascular investigation in the type 2 diabetic mellitus (T2DM) patients. Aim. To estimate the prevalence of ED and its associated determinants in a sample of male patients with new or recently diagnosed T2DM. Methods. The SUBITO-DE study is an observational, multicenter, prospective study involving 27 Italian diabetes centers. Male patients recently diagnosed with T2DM were consecutively interviewed by their attending physician at the diabetes care centers and asked whether they had experienced a change in their sexual function or found it unsatisfactory. Those responding positively were then invited to participate in the study. Main Outcome Measure. Several hormonal and biochemical parameters were studied. Results. A nonselected series of 1,503 patients was interviewed, 499 of which (mean age, 58.8 ± 8.8 years) entered the study, yielding a final enrolment rate of 33.3%. ED was classified as mild in 19.4%, mild-to-moderate in 15.4%, moderate in 10.4%, and severe in 21.6% of patients, respectively. In addition, premature ejaculation, delayed ejaculation, and hypoactive sexual desire (HSD) were comorbid in 28.3%, 32.9%, and 58.4%, respectively. Finally, hypogonadism, showed an estimated prevalence of almost 20%. Both organic (at least one chronic DM-associated complication) and psychological factors (severe depressive symptoms) increased the risk of ED. Severe depressive symptoms were also associated with ejaculatory problems, HSD, and hypogonadism. Conclusions. A high prevalence of sexual dysfunction in men with recently diagnosed T2DM was detected. Early diagnosis of ED could help prevent emotional and physical discomfort in men and aid in identifying reversible cardiovascular risk factors. Screening of sexual dysfunction should become a part of routine care in the management of T2DM patients

    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
