Estructura factorial del compañero de trabajo ideal

La satisfacción laboral es uno de los componentes de importancia en la elaboración de estrategias para la gestión del capital humano debido al gran impacto que tiene en el crecimiento y desarrollo de las organizaciones. Una de las variables de mayor influencia y poco estudiadas de esta satisfacción, es la satisfacción con los compañeros de trabajo. Por este motivo, el presente estudio busca identificar la estructura factorial del compañero de trabajo ideal, es decir, el conjunto de características esperadas en el colaborador perfecto. La muestra estuvo compuesta por 60 participantes para la fase cualitativa y 151 participantes para la fase cuantitativa, con un rango de edad entre los 22 y 36 años. El análisis factorial exploratorio encontró cuatro factores: "buenas relaciones personales", “correcto, organizado y seguro de sí mismo”, “trabaja en equipo, empático y flexible ”y “productivo y que sabe enseñar”. No se encontraron diferencias significativas que relacionaran estos factores con alguna variable demográfica de los participantes (género, edad, nivel socio-económico, universidad, tipo de colegio, años de experiencia laboral y tiempo de permanencia en la empresa actual).Estudios previos encontraron que estos factores se relacionan con diversos aspectos de la gestión del comportamiento humano, tales como: productividad, retención de líderes talentosos, compromiso, absentismo, motivación, intención de renuncia y desempeño. Estos resultados contribuyen a la mejora de la satisfacción laboral y la productividad considerando el contexto peruano.The Job satisfaction is one of the most important components in the companies’ environment, due to its impact in the growth and development of the organization. Likewise, one of the most influential and poorly researched variable of this satisfaction is the Coworker satisfaction. Thus, the purpose of this study was to examine the factorial structure of the ideal coworker based on the related perceptions of a Peruvian workforce to further investigate the elements of coworker satisfaction within the human resources field. Participants for this study were 60 who were interviewed during a qualitative phase, and 151 participants interviewed during a quantitative phase, between the age range of 22 to 36 years of age. After an exploratory factor analysis, results indicated the presence of four factors: “good personal relationships”, “assertive, organized and self-confident”, “team player, empathetic and flexible” and “productive and good teacher”. There were no statistical significant differences found between factors and demographic characteristics (gender, age, socio-economic status, education, years of work experience, time working in the current company). Furthermore, previous evidence suggests that these factors are related to different aspects of the human resources management, such as: productivity, retention of talented leaders, employee engagement, absenteeism, turnover intention and employee performance. These results contribute to the improvement of the work satisfaction and productivity in a Peruvian work setting.Tesi

Coxiella burnetii Phagocytosis Is Regulated by GTPases of the Rho Family and the RhoA Effectors mDia1 and ROCK

The GTPases belonging to the Rho family control the actin cytoskeleton rearrangements needed for particle internalization during phagocytosis. ROCK and mDia1 are downstream effectors of RhoA, a GTPase involved in that process. Coxiella burnetii, the etiologic agent of Q fever, is internalized by the host´s cells in an actin-dependent manner. Nevertheless, the molecular mechanism involved in this process has been poorly characterized. This work analyzes the role of different GTPases of the Rho family and some downstream effectors in the internalization of C. burnetii by phagocytic and non-phagocytic cells. The internalization of C. burnetii into HeLa and RAW cells was significantly inhibited when the cells were treated with Clostridium difficile Toxin B which irreversibly inactivates members of the Rho family. In addition, the internalization was reduced in HeLa cells that overexpressed the dominant negative mutants of RhoA, Rac1 or Cdc42 or that were knocked down for the Rho GTPases. The pharmacological inhibition or the knocking down of ROCK diminished bacterium internalization. Moreover, C. burnetii was less efficiently internalized in HeLa cells overexpressing mDia1-N1, a dominant negative mutant of mDia1, while the overexpression of the constitutively active mutant mDia1-ΔN3 increased bacteria uptake. Interestingly, when HeLa and RAW cells were infected, RhoA, Rac1 and mDia1 were recruited to membrane cell fractions. Our results suggest that the GTPases of the Rho family play an important role in C. burnetii phagocytosis in both HeLa and RAW cells. Additionally, we present evidence that ROCK and mDia1, which are downstream effectors of RhoA, are involved in that processFil: Salinas Ojeda, Romina Paola.

An examination of the Spanish translation of the 50-item IPIP Big-five inventory in a Spanish speaking Peruvian sample

The International Personality Item Pool (IPIP) five-factor model inventories are a widely used resource for personality research and have been translated into multiple languages. However, the extent of the psychometric assessment of translated scales is variable. Here we present a structural analysis of one Spanish translation of the 50-item IPIP five-factor inventory in a sample of Peruvian non-university educated working adults (n=778). A global confirmatory factor analytic (CFA) model of the a priori five factors failed to fit. So too did single factor models for four of the five factors, the exception being Neuroticism. Fit was improved via use of an exploratory structural equation measurement model, but the resultant solution showed very poor theoretical coherence. The pattern of factor loadings suggested that the lack of coherence might be due to the effects of the valence of item wording. CFA models including five substantive factors and a series of method factors modelling shared covariance based on item wording, improved fit and coherence. This investigation suggests that the tested Spanish translation, without explicitly modelling method factors, may not be suitable for use in certain Spanish-speaking countries or samples composed of non-university educated participants
