TL;DR: In this paper, a mesoporous nano-fibrillar alumina was synthesized by hydrolysis-precipitation route from aqueous solution of aluminum sulfate analytical reagent (AR).
Abstract: This study reports the synthesis of mesoporous nano-fibrillar alumina prepared by hydrolysis-precipitation route from aqueous solution of aluminum sulfate analytical reagent (AR) compared to aluminum sulfate technical grade (TG) of low purity under similar conditions using ammonia as the precipitating agent. The phisicochemical properties of these samples was studied with the assistance of characterization techniques such as Thermogravimetric and differential thermal analysis (TG/DTGA–DTA), X-ray diffraction (XRD), N2 adsorption-desorption isotherms, Fourier transform infrared (FTIR) spectroscopy, particles size and Transmission electron microscopy with energy-dispersive X-ray analysis (TEM/EDAX). The TG-DTA and XRD results show greater stability and a slightly greater crystallinity in Al2O3-TG sample than Al2O3-AR. N2 adsorption-desorption results show for both materials greatly surface area of 311 m2/g for Al2O3-TG and 272 m2/g for Al2O3-AR exhibiting characteristics of mesoporous materials. The FTIR results show a lower percentage of surface OH groups for Al2O3-TG showing a lower acidity due to the lower concentration of Al-OH species (AlIV). TEM measurements confirmed fibers size ranged from 20 to 100 nm for Al2O3-TG and 20-80 nm for Al2O3-AR. EDAX shows the presence of 0.20 % atomic of Mg as an impurity in Al2O3-TG, is attributed that this amount is sufficient to generate structural defects and decrease slightly acidity, likewise, extended the fibrillar chain of the alumina.

TL;DR: In this article, the authors describe and analyze the caracteristicas of the presente trabajo, as well as its implicaciones in the satisfaccion laboral de los trabajadores, concluyendo que entre los factores fundamentales de la motivacion and satisfaccions laborales, se encuentran las relaciones and la comunicacion informal, asi como the imagen o percepcion de la conducta del dueno o director general.
Abstract: El objetivo del presente trabajo es describir y analizar las caracteristicas de la organizacion del trabajo (tamano de la fuerza laboral, objeto del trabajo, medios de produccion, division y distribucion del trabajo), asi como sus implicaciones en la satisfaccion laboral de los trabajadores. El estudio se basa en las entrevistas a 16 miembros de una organizacion, concluyendo que entre los factores fundamentales de la motivacion y satisfaccion laborales, se encuentran las relaciones y la comunicacion informal, asi como la imagen o percepcion de la conducta del dueno o director general

TL;DR: In this article, a study was conducted to determine the consistencia interna de la escala de Actitudes hacia Lesbianas and Hombres Homosexuales (ATLG) and its factores, determinar the estructura factorial and comprobar su invarianza entre hombres and mujeres.
Abstract: Este estudio tiene como objetivos calcular la consistencia interna de la escala de Actitudes hacia Lesbianas y Hombres Homosexuales (ATLG) y sus factores, determinar la estructura factorial y comprobar su invarianza entre hombres y mujeres. Se levanto una muestra incidental de 356 estudiantes. Los 20 items fueron consistentes (α = .94). Se definio un factor de actitud hacia las lesbianas (.91) y dos factores de rechazo abierto (.85) y sutil (.78) hacia los hombres homosexuales. Esta estructura de tres factores correlacionados tuvo un ajuste adecuado a los datos y resulto estable entre hombres y mujeres. Se recomienda su uso en Mexico.

Abstract: The Resources and Capabilities Theory (RCT) is one of the main theoretical models that guide the research conducted in Strategic Management, and its use is growing. This trend, which began in the eighties of the last century, by various factors, among which acceptance is explained within the academic community associated with strategic management, economic arguments used in this approach to explain the behavior and performance of the company, and in particular mechanisms for building and maintaining competitive advantage. The RCT considers that the provision of a competitive advantage says that the company has reached a higher level of performance than its competitors, a situation that allows you to make abnormal profits, even in the long run. In this sense, build and sustain a competitive advantage is the key to success of the company and indicates how efficiently the company uses its resources and capabilities. Method : In order to verify that the ideas mentioned above and in particular that what is indicated by Barney et al . (2011) is still valid and corresponds to the publications in the field, a bibliometric data analysis is performed for the period 2011-2015 (August ). The data were obtained from the Scopus database and analyzed using Excel software. This analysis identifies the main research topics that are treated in the CRT, as well as the trend that continues in its development. The method and software used is similar to that used in several bibliometric analyzes reported in the international literature (Ramos-Rodriguez and Ruiz-Navarro 2004, 2008, Gonzalez-Albo and Zulueta 2007, Portugal Ferreira, Ribeiro Serra, Kramer Costa, and Almeida 2016 and Acevedo, N., Jimenez, L. and Rojas M. 2017) Results : The data obtained show a growing generation of empirical confirmatory test, application development and contribution of the RCT to the development of other disciplines. Conclusion: Strengthening and maturity of the RCT is manifested through publications identified in this analysis of bibliometric data. While the field of RCT is broad and does not allow to deepen in all its dimensions, it can be concluded that the results obtained in this study confirm that it is correct perception of the RCT as one of the most important theoretical models for research performs in strategic management.

TL;DR: In this article, the authors describe the Attitudes Towards Lesbians and Gays scale (ATLG; Herek, 1984) distribution and provide validity evidence and recommend its use in Mexico.
Abstract: The aims of this paper were to describe the Attitudes Toward Lesbians and Gays scale (ATLG; Herek, 1984) distribution and to provide validity evidence. An incidental sample of 356 students was collected. The total score distribution was adjusted to a normal curve. Its correlation with the Homophobia scale (EHF; Moral & Martinez-Sulvaran, 2010) was .76. It showed the difference between men and women, between persons that are defined heterosexual and those that are defined non-heterosexual, and within the heterosexual persons between those that have homosexual friends or relatives and those that not; what provides validity proofs. We recommended its use in Mexico.
