Occupational Safety Knowledge Management with Performance Indicators as a Strategy for the Reduction of Accidents in the Construction Sector in Mexico

The construction industry is one of the key contributors to a country's economy. It accounts for 13.4% of total annual production. The construction sector has specific characteristics such as dynamic work and uncertain conditions; therefore, it tends to cause occupational accidents. Another one of its features is the temporary nature of its projects. This characteristic leads to the loss of learning and disappearance of workers at the end of each project inhibiting workers from gaining experience. The aim of this paper is to propose a model of knowledge management in occupational safety that limits or stops the loss of knowledge, covers the dynamic needs of the construction sector and helps to reduce accidents at work. The present research method is exploratory; it identifies the elements or strategies of the stages of knowledge management that allow the reduction of accidents in the construction sector. As a result of this research, the authors have proposed a model which is able to manage the knowledge generating learning from its elements. Some key safety performance indicators as strategies to reduce occupational accidents are discussed

Evaluación Del Impacto De La Política Pública “Programa De Estímulos A La Innovación”, En El Contexto De Propiedad Industrial En México

In order to trigger economic and technological development in Mexico, the government of this country is trying different ways to boost innovation. One of them is through the public policy "Program of Stimuli for Innovation (PSI)". This consists of granting subsidies to companies for the development and commercialization of technological innovations that trigger new markets. However, although annual reports of the PSI management have been generated, studies conducted to evaluate this program in terms of industrial property appropriation are still unknown. For the foregoing, the object of this studywas to evaluate the PSI to know its national impact in terms of appropriation of industrial property in the period 2009-2016. The evaluation consisted of making a quantitative, statistical, descriptive and inferential analysis of the PSI, using databases generated by Mexican public institutions. The results of this research showed that although the PSI grants motivated the link between research centers and companies for the development of innovative technologies, the appropriation of industrial property managed by Mexicans was modest. Likewise, it was found that the grants were not granted in an equitable manner to the different types of companies that participated in the program. Concluding that it is necessary to evaluate and supervise this public policy with objective indicators that allow it to be more effective. It is expected that this study will contribute to making a proposal for improvement to this public policy that contributes to the economic and technological growth of this country

Before and After the Reform: Fixed Line Internet Penetration in Mexican Households

Purpose – Despite being the second largest mobile market in Latin America regarding subscribers, Mexico’s penetration levels remain lower than the regional averages. The aim of this paper is to evaluate whether the Mexican 2013 Telecommunications and Broadcasting Reform helped mitigate or exacerbate the digital divide. In particular, we evaluate if the Reform had an impact on fixed-line internet penetration in Mexico. Methodology/approach/design – For the assessment, the 2010 Census and 2015 Intercensal Survey data used to create impact indexes through Generalized Linear Models (GLMs) estimations. Findings – Through a quintile analysis were confronted by results, with the intention of showing the average of internet penetration in each income group. The data obtained suggest that internet penetration had positive variations in all the quintiles indicating that recent regulatory changes in telecommunications matter had helped to reduce the digital divide. Practical implications – The poor and vulnerable groups remain at the digital exclusion; these groups need more digital inclusion actions

VNIR-SWIR using OreXpress spectroradiometer as a spectral approximation method to differentiate epithermal mineralization alteration phases. A case study from Jacinto and Big Golden Hill, Cuba

Spectral differences (range: 350-2500 nm) between the three alteration phases related to low and high sulfidation epithermal mineralization has been studied in the Jacinto deposit (Beatriz, Sur de Elena, and El Limon Nuevo veins) and the Big Golden Hill sector, respectively, located in the Cuban Cretaceous volcanic, Camagüey and Las Tunas provinces. This study has revealed the following differences between the phases: (a) Phase I: associated with the lithological type of quartz with massive and/or brecciated texture, where gold mineralization develops. At 600-800 nm, the signals identified responds with goethite and at 1400, 1900 y 2200 nm, as montmorillonite and nontronite. The reflectance value is 30 -50%, although in the El Limón Nuevo vein is 30-40%. (b) Phase II: Related to the argillic alteration zone composed by sericitic or silicified quartz and ferrous minerals such as limonite and hematite. It only occurs in Beatriz and Sur de Elena veins. At 600-800 nm, the signal is associated with ferrous minerals and at 1400, 1900, and 2200 nm, to clays minerals as montmorillonite, halloysite, and nontronite. The reflectance value is 30 – 50%. The difference between both Phases is in the amplitude and shape of the absorption feature at 1400 nm. (c) Phase III: it is located near the volcanic rock, composed by illite-smectite-quartz, without gold content and nearby to propylitic zone. At 600-800 nm, the feature indicates the presence of goethite and at 1400, 1900, and 2200 nm, to montmorillonite, illite, and nontronite. The reflectance value is 30 - 40%. The Big Golden Hill sector is characterized by peaks related to goethite and nontronite at 600-800 nm and pyrophyllite at 1400, 1950 and 2165 nm, typical of advanced argillic alteration. The reflectance value reaches 55%. This study represents one of the first applications of reflectance spcetroscopic techniques in Cuban mineral deposits

Universidad Autónoma Metropolitana. Departamento Economía; México.Para hacer frente a una crisis económica, las organizaciones implementan acciones recesivas como la reducción de salarios o de personal, afectando la satisfacción de los empleados y el rendimiento de la organización. Bajo esta premisa, el objetivo de esta investigación es presentar lo que existe en la literatura sobre las repercusiones de las crisis económicas en la satisfacción laboral. Diversas investigaciones señalan que la satisfacción laboral es un factor clave en la retención y el compromiso de los empleados; por lo tanto, conocer los factores que influyen en esta permitirá diseñar estrategias para aumentar dicha percepción en situaciones de inestabilidad económica. Mediante una revisión sistemática, consistente en la lectura a profundidad de 36 artículos, se concluye que la satisfacción laboral, de forma general, no se ve afectada significativamente por un periodo de crisis económica; sin embargo, existen ciertos aspectos como el salario, los entornos laborales, los tipos de contrato, las diferencias culturales y de género que sí influyen en dicha percepción. Los resultados de esta investigación pueden convertirse en herramientas útiles para las empresas como una ayuda para enfrentar los efectos adversos de una crisis económica de manera más eficiente mediante la retención de empleados idóneos para lograr la continuidad operativa de la organización.To face an economic crisis, organizations implement recessive actions such as reducing salaries or personnel, affecting employee satisfaction and the organization's performance.

Visiones de la educación financiera: Análisis y perspectivas

"Visiones de la educación financiera: análisis y perspectivas es una obra que enmarca la importancia de la educación financiera en la sociedad en el contexto actual. Las decisiones que en este tema realiza un individuo pueden impactar positiva o negativamente su estabilidad económica por un periodo indeterminado, es aquí cuando la educación financiera actúa como una herramienta trascendental en su bienestar personal. Además de tener la función de armadura ante las batallas que se libran en los mercados —como la crisis financiera de 2008— funge como dinamizador de las economías al potenciar los proyectos de inversión con el aumento del emprendedurismo, impactando así en las variables macroeconómicas. Esta área del conocimiento ha adquirido importancia y popularidad a nivel internacional a raíz de las crisis económicas de los últimos años, sin embargo, aún existen, entre otras, brechas sociodemográficas, culturales, económicas, que no permiten el acceso a estas enseñanzas, excluyendo parte de la población del proceso del bienestar económico. Para ejemplificar esta desigualdad, en los capítulos se plasma un panorama internacional de la educación financiera, considerando las implicaciones y retos que han tenido las estrategias nacionales de educación financiera a nivel mundial"

Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

Cosmological and astrophysical observations suggest that 85\% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challenging and fundamental open questions of particle physics. Assuming particle DM, this exotic form of matter cannot consist of Standard Model (SM) particles. Many models have been developed to attempt unraveling the nature of DM such as Weakly Interacting Massive Particles (WIMPs), the most favored particle candidates. WIMP annihilations and decay could produce SM particles which in turn hadronize and decay to give SM secondaries such as high energy $\gamma$ rays. In the framework of indirect DM search, observations of promising targets are used to search for signatures of DM annihilation. Among these, the dwarf spheroidal galaxies (dSphs) are commonly favored owing to their expected high DM content and negligible astrophysical background. In this work, we present the very first combination of 20 dSph observations, performed by the Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS collaborations in order to maximize the sensitivity of DM searches and improve the current results. We use a joint maximum likelihood approach combining each experiment's individual analysis to derive more constraining upper limits on the WIMP DM self-annihilation cross-section as a function of DM particle mass. We present new DM constraints over the widest mass range ever reported, extending from 5 GeV to 100 TeV thanks to the combination of these five different $\gamma$-ray instruments
