Determinación de los efectos en la salud de los trabajadores del programa de control de vectores expuestos laboralmente a organoclorados en tres departamentos de Colombia 2013
No full textObjetivo: Evaluar la exposición a plaguicidas organoclorados empleados en salud publica en la población trabajadora del programa de control de vectores en tres regiones de Colombia en 2013.\ud
Métodos: Se realizó un estudio descriptivo de corte transversal en el grupo de trabajadores del programa de control de enfermedades transmitidas por vectores -ETV- (coordinadores, técnicos, entomólogos, técnicos y auxiliares) de los departamentos de Meta, Nariño y Risaralda. A todos los participantes se les realizó una entrevista en la cual se recogió, mediante cuestionario, información de las tres variables de muestreo: sociodemográficas, ocupacionales, clínicas y toxicológicas. Se determinaron los niveles de 13 organoclorados en suero mediante cromatografía de gases en el Instituto Nacional de Salud. Se llevó a cabo un análisis descriptivo y se llevo a cabo un análisis para determinar la distribución de medias entre variables de exposición ocupacional (Ji2 para cualitativas y U de Mann-Whitney para cuantitativas). Posteriormente, se llevó a cabo un análisis multivariado para estimar la asociación controlando por variables de antigüedad, exposición laboral a organoclorados.\ud
Resultados: El reporte de manipulación de insecticidas organoclorados fue del 39,1%. El 100% de los trabajadores que usaron organoclorados refirieron el uso DDT. El 7,5% (n=3) refirieron el uso de Aldrin. Los organoclorados fueron hexaclorbenceno, hexaclorocicloexano, heptacloro, heptaclorepoxi, α-Clordano, 4,4-DDT, 4,4-DDE, β -endosulfan, 2,4- DDT, endosulfan sulfato y mirex. Los organoclorados con niveles pico más altos fueron β-HCH, 4,4- DDT y α –HCH. Los síntomas de mayor presentación fueron: cefalea 28,7%, mareo 29,9%, disminución de fuerza en MMSS 17,2% y síntomas neurosiquiátricos.Salud InteligenteInstituto Nacional de SaludObjective: To assess exposure to organochlorine pesticides used in public health in the working population of the vector borne control programme in three regions of Colombia in 2013.\ud
Methods: A descriptive cross-sectional study was performed in the group of workers control program vector borne - ETV- (coordinators, technicians, entomologists, technicians and assistants ) in the departments of Meta, Nariño and Risaralda diseases. All participants underwent an interview in which was collected by questionnaire , information from the three sampling variables : sociodemographic , occupational , clinical and toxicological . Organochlorine 13 levels in serum were determined by gas chromatography in the National Institute of Health . They conducted a descriptive analysis was conducted and an analysis to determine the distribution of means between occupational exposure variables ( Ji2 for qualitative and Mann- Whitney for quantitative ). Subsequently, we conducted a multivariate analysis to estimate the association of variables controlling for age , occupational exposure to organochlorines.\ud
Results: The report handling organochlorine insecticides was 39.1 %. 100 % of workers reported that they used organochlorine DDT use . 7.5% (n = 3 ) reported the use of Aldrin. Organochlorines were hexachlorbenzene, hexachlorocyclohexane, heptachlor, heptaclorepoxi , α - chlordane , 4,4 -DDT , 4,4 -DDE , β - endosulfan , 2,4 - DDT , endosulfan sulfate and mirex. Organochlorines with higher peak levels were β -HCH , 4,4 - DDT and α -HCH. The symptoms of major presentation were headache 28.7 % , dizziness 29.9 % , decreased strength in MMSS 17.2% and neuropsiquiatric 20%

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
