As many translocal and cross-border traders, mukheristas cover thousands of miles every week to supply urban markets, thus feeding themselves, their families and the cities they connect.
After an intensive field work travelling with mukheristas between Maputo (Mozambique) and Johannesburg (South Africa), the author shows the role of complex hybrid practices of trans-local mobility in shaping cities and territories in sub-saharan Africa.
A "research on the road" to reflect on the political relevance of informal mobile practices in troubled urban societies, but also on new theoretical concepts and empirical research approaches.
In a world where change is extremely rapid and new issues emerge unremittingly, 'Mobile urbanity' opens up new ways of thinking the spatial dimensions and the agency embraced in human mobility

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
Hip fracture in Italy: analysis of DRG data
No full textHip fractures are associated with a high rate of mortality, especially in the elderly, and have high social and economic burdens. The impact of femoral fractures is of particular importance in countries like Italy, with a progressively aging population. In Italy, over 120,000 surgical hip interventions were performed in 2002; of these, more than 72,000 were directly attributable to femoral fractures. Between 1999 and 2002, the number of operations for femoral fractures increased by 7.1%, and each year saw a predominance of women and elderly people, in line with the increased prevalence of osteoporosis. According to the data the prevalence of hip fractures is increasing in Italy, and women and the elderly are the most affected. We urgently need primary prevention programs to sensitize the population to the risks of osteoporotic fractures and to reduce its incidence, especially in high-risk subjects
