The objective of the present study was to specify a model for the study of the relationships between agenda effects, framing, priming and melding. A documentary, retrospective and exploratory study was conducted with a selection of sources indexed to international repositories, considering the year of publication and the keyword algorithm. Differences were evidenced between the published literature and the qualifications of judges who are experts in the field, although the design of the work limited these findings to the search algorithm, suggesting the extension of the study to the indicative logic of credibility and verifiability of the information disseminated in the media.

In this study, a new methodology is proposed to perform optimal selection of conductors in three-phase distribution networks through a discrete version of the metaheuristic method of vortex search. To represent the problem, a single-objective mathematical model with a mixed-integer nonlinear programming (MINLP) structure is used. As an objective function, minimization of the investment costs in conductors together with the technical losses of the network for a study period of one year is considered. Additionally, the model will be implemented in balanced and unbalanced test systems and with variations in the connection of their loads, i.e., Δ− and Y−connections. To evaluate the costs of the energy losses, a classical backward/forward three-phase power-flow method is implemented. Two test systems used in the specialized literature were employed, which comprise 8 and 27 nodes with radial structures in medium voltage levels. All computational implementations were developed in the MATLAB programming environment, and all results were evaluated in DigSILENT software to verify the effectiveness and the proposed three-phase unbalanced power-flow method. Comparative analyses with classical and Chu & Beasley genetic algorithms, tabu search algorithm, and exact MINLP approaches demonstrate the efficiency of the proposed optimization approach regarding the final value of the objective function.

The public image of psychiatry has been tarnished in recent years. In order to determine the extent to which press coverage has contributed to negative attitudes towards psychiatry, we conducted a content analysis of a random selection of newspaper articles which appeared over a twenty-year period in two different newspapers. We found that although there had been some minor, cosmetic changes over the years, such as more appropriate headlines and more direct quotes from psychiatric experts, on the whole, content and attitudes had changed very little. An accuracy check of media reporting of forensic cases over a 20-year period revealed that when reporters have access to written material, the accuracy levels are greatly improved.

Antecedentes. La complejidad ambiental observada en una localidad ha sido estudiada a través de un modelo isomórfico en el que se anticipa la emergencia de dos identidades: una entrópica y otra neguentrópica. En situaciones de riesgo, escasez e insalubridad, las comunidades se organizan para reducir los efectos de los desastres naturales sobre la salud comunitaria. Objetivo. Especificar un modelo para el estudio del estrés y la resiliencia comunitaria ante los eventos de riesgo ambiental y los desastres naturales. Método. Se llevó a cabo un estudio no experimental, transversal y exploratorio con una selección no probabilística de 600 afectados por las inundaciones de un rio en la zona del centro de México. Resultados. Se encontraron diferencias significativas entre hombres y mujeres con respecto a sus niveles de riesgo, estrés y resiliencia que sirvieron para especificar el modelo de relaciones de dependencia entre las variables que explican la complejidad ambiental isomórfica. Discusión. En relación con otras especificaciones de modelos se recomienda incluir las variables con la finalidad de demostrar las trayectorias lógicas de relaciones de dependencia propuestas.Background. Environmental complexity observed in one locality has been studied through an isomorphic model in which the emergence of two identities are anticipated: an entropic and other neguentropic. At risk, shortages and unsanitary conditions, communities are organized to reduce the effects of natural disasters on community health. Objective. Specify a model for the study of stress and community resilience to environmental risk events and natural disasters. Method. a non-experimental, cross-sectional and exploratory study with a nonrandom selection of 600 affected by the flooding of a river in the downtown area of Mexico was held. Results. significant differences between men and women regarding their risk levels, stress and resilience that served to specify the model of dependency relationships between variables that explain the environmental complexity isomorphic found. Discussion. For other specifications recommended models include variables in order to demonstrate the logical paths proposals dependency relationships.

This is a study of high school students’ attitudes toward the English language in Lebanon. The purpose of this research is to assess the extent of use of English inside and outside the schools taking into consideration the attitude towards the language. Two schools were selected, one upper middle class and one lower middle class. This selection of different social classes aims at finding whether a student’s socio- economical background affects his/ her attitude toward the English language. The sample of respondents returned 52 questionnaires from the two schools. Although this sample was a modest one, it highlighted the differences in attitudes towards the English language, but these attitudes did not relate much to the socioeconomic class as much as personal preferences. However, what was salient in this research is how students from the lower middle class were more inclined to use English to raise their social status and both groups agreed that English is essential to their progress in life.
