Why urbanisation and health?
No full textIn 2007 more than 50% of the world's population were living in metropolitan cities, which was the first time in history that the urban population level had risen above 50%.The urban population have grown ever since and will continue to do so according WHO estimates. By 2030it has been estimated that 6 people out of 10 will live in urban agglomerates and an estimate of 70% of the inhabitants will be living in urban environments by 2050

Evaluation of premature ejaculation.
No full textIntroduction. Premature ejaculation (PE) is a prevalent, yet often underdiagnosed, sexual disorder that affects men of all ages. Identification of PE is hampered by stigma and embarrassment associated with the condition, and limited awareness that it is treatable. Because diagnosis informs treatment decisions that have an impact on clinical outcomes, the ability to diagnose PE accurately is vital to the successful management of this condition. Aim. Provide an overview of how to evaluate and diagnose PE. Methods. Review of the literature. Main Outcome Measures. The taxonomy of PE based on onset, time, type, and comorbidities. Results. Diagnosis of PE encompasses seven key steps: (i) Obtaining the patient's general medical and sexual history; (ii) Classifying the symptom on the basis of onset (e.g., lifelong or acquired PE), timing (e.g., prior to or during intercourse), and type (e.g., absolute/generalized or relative/situational); (iii) Involving the partner to determine their view of the situation and the impact of PE on the couple as a whole; (iv) Identifying sexual comorbidities (e.g., erectile dysfunction) to define whether PE is simple (occurring in the absence of other sexual dysfunctions) or complicated (occurring in the presence of other sexual dysfunctions); (v) Performing physical examination to check the man's sexual organs and reflexes; (vi) Identifying underlying etiologies and risk factors (e.g., endocrine-, urological-, or psychorelational-/psychosexual-related) to determine the primary cause of PE and any associated comorbidities; (vii) Discussing treatment options to find the most suitable intervention, according to the needs of the man and his partner. Conclusion. A greater understanding of how to diagnose PE correctly, and a more widespread use of a structured diagnostic approach, could lead to better treatment outcomes in the future.

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
