[Invisibility of working conditions and children's health in the Felipe Angeles market]. [La invisibilidad de las condiciones laborales y de salud de niños del mercado Felipe Angeles.]
No full textIdentifying the work environment and health of children working in the Felipe Angeles market in Guadalajara. This was a descriptive study which included 198 children working in the aforementioned market. A questionnaire was used which asked about the sociodemographic variables, the work environment and the health of such children. The children working in the market were predominantly male (89.9 %), aged 6 to 17 years old, residing in Guadalajara; 71 % were attending school. 83 % of the children had started working in the market between 7 to 10 years old and 75 % had worked there for 1 year or more. Workdays lasted all week, without rest in 50 % of the cases. The children perceived health risks as concerning abrasion, contusion, fractures, being run over and other psychosocial types related to becoming the victims of theft or becoming addicts. The children's work environment and health were not suitable for their age and affected their physical and psychosocial state as the site had deficient architecture making it impossible to carry out activities appropriate for their age and provoked workplace risk for which there was no prevention

Trend of mortality from burns in Mexico, 1979-2009 [Tendencia de mortalidad por quemaduras en méxico, 1979-2009]
No full textObjective: To describe the trends in burn-related mortality rates in Mexico from 1979-2009. Methods: Burn-related mortality standardized rates and trends were estimated from official mortality data in Mexico. Variables included were: age, sex, federal state and year of death. Results: From 1979-2009, 33,333 burn-related deaths were registered. During this period, the burn-mortality rate decreased, stating from a rate of 2.32/100,000 in 1979 and dropping to 0.72/100,000 in 2007, but in 2008 and 2009 the mortality rates occurred in the states of Baja California, Chihuahua, Baja California Sur, Sonora and Durango, all of these states in the northwest of Mexico. Men were twice as likely as women to die from burns. Conclusions: Mortality caused by burns in Mexico presents a descendent tendency in most of the states of the Country, with the exception of the northwest region, which may be related to the lack of specialized units in the treatment of burn distance between the population centers and the specialized attention units
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
