Rotación laboral en Gilat to Home Perú S.A.
No full textGilat to Home Perú S. A. (Gilat) es una empresa transnacional cuya casa matriz se encuentra en Israel. Ingresó al mercado peruano hace doce años y se encarga de brindar soluciones y servicios de telecomunicación en zonas rurales a empresas del sector público y privado, así como a empresas internacionales del mismo grupo. En la actualidad está integrada por 119 colaboradores que tienen una edad promedio de 34 años, son profesionales universitarios y técnicos en las especialidades de Ingeniería, Contabilidad, Administración, entre otras. En los últimos tres años, Gilat presenta un alto índice de rotación que alcanza el 98%. Con la finalidad de revertir esta situación se han implementado varias acciones que han mejorado las condiciones de trabajo y han significado algunos cambios positivos para los colaboradores, pero no ha disminuido el índice de rotación. Como profesionales del área de Recursos Humanos, consideramos que el índice de rotación es parte de los indicadores que se contemplan dentro de nuestra gestión, por lo que ofrecemos una propuesta de mejora en nuestras organizaciones utilizando este indicador. La investigación es de tipo cualitativa y tiene como objetivo identificar y analizar las causas internas que influyen en la rotación laboral de los colaboradores de Gilat, así como diseñar una propuesta de gestión. Para tener esta información se han aplicado entrevistas de diagnóstico a veintinueve colaboradores que trabajan actualmente en la organización. Cabe destacar que la información de las entrevistas de salida que corresponden al período 2010-2012. El análisis e interpretación de estos datos han sido tomados de los modelos teóricos descritos por Idalberto Chiavenato y Frederick Herzberg, diferenciando las causas internas de rotación en función a la satisfacción del factor higiénico y del factor motivacional. Los resultados obtenidos son el punto de partida para la propuesta de mejora que diseñamos con el objetivo de proveer un plan que contribuya a la gestión del índice de rotación laboral, el diseño de estrategias enfocadas en oportunidades de desarrollo, prácticas de comunicación interna y revisión de las remuneraciones. Asimismo, esperamos preparar a los colaboradores para asumir futuros retos y acompañarlos en el proceso, mantenerlos motivados y obtener el compromiso con la organización a mediano y largo plazo
Exploring young students creativity: The effect of model eliciting activities
No full textThe aim of this paper is to show how engaging students in real-life mathematical situations can stimulate their mathematical creative thinking. We analyzed the mathematical modeling of two girls, aged 10 and 13 years, as they worked on an authentic task involving the selection of a track team. The girls displayed several modeling cycles that revealed their thinking processes, as well as cognitive and affective features that may serve as the foundation for a methodology that uses model-eliciting activities to promote the mathematical creative process
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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

Ethnic and gender differences in perceptions of mortality risk in a Canadian urban centre
No full textGilat L Grunau1, Pamela A Ratner1,2, Shahadut Hossain11NEXUS; 2School of Nursing, University of British Columbia, Vancouver, Canada; University of British Columbia, Vancouver, CanadaBackground: Women reportedly do not perceive heart disease (HD) as a major threat to their health; however, men’s perceptions are rarely studied.Purpose: We explored gender and ethnic differences in risk perception of HD mortality.Methods: The survey was completed by 976 people 40+ years of age, in metropolitan Vancouver, Canada.Results: Men, compared with women, were more likely not to know the answer to a question about whether HD is the most common cause of death for women; however, women were more likely not to know the answer to a question about whether HD is the most common cause of death for men. Chinese-Canadian and South Asian-Canadian participants were more likely than participants of other ethnic groups not to know the answer to either question, and the Chinese-Canadian participants were more likely to disagree that HD is the most common cause of death for women.Conclusion: There is a need to educate the Chinese-Canadian and South Asian-Canadian communities about HD as a first step in promoting health behavior change. Men and women must be educated about the other gender’s risk of HD because all adults play integral roles in making decisions about the prevention of and early intervention for HD.Keywords: risk assessment, heart disease, mortality, gender, ethnic group
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
A novel scheme for inserting manufactured viscous dampers in building structures
No full textThis paper summarizes the results of a number of research works carried by the authors over the years in order to identify the “optimal” way of inserting manufactured viscous dampers in shear-type structures. The novel scheme proposed here as “optimal” (and referred to as “the MPD system”) is based upon the mass proportional component of the Rayleigh damping matrix (MPD matrix) and is characterised by a peculiar damper placement which sees the dampers placed so that they connect each floor to a fixed point.
Firstly, the paper briefly recalls (a) the physical principles and (b) selected results of numerical investigations which show that the MPD system is characterised by superior dissipative properties.
Secondly, the paper investigates the implementation of the MPD system in civil building structures
