    La presente monografía tiene como objetivo brindar información sobre cómo fueron los orígenes de la educación josefina en el casco urbano. La investigación consta de tres capítulos y contiene datos valiosos como por ejemplo hallazgos de acontecimientos generales del pueblo que enriquece la información ya existente, fechas de acuerdos de fundación de los diferentes centros educativos, desconocidos en su mayoría por la comunidad educativa y docentes de antaño que a la presente fecha han sido olvidados por las nuevas generaciones. El registro histórico se basó en fuentes primarias y secundarias para dar mayor confiabilidad en la interpretación de los hechos. Las diferentes entidades dentro y fuera del municipio contribuyeron con el aval respectivo para poder accesar a esa documentación histórica. Además, se entrevistaron a personas con una mente lúcida que vivieron en épocas del pasado con el fin de corroborar datos escritos, lagunas históricas y elaboración de biografías. Este es un trabajo con varios años de investigación y como se citaba al inicio con una responsabilidad de dar a conocer el registro histórico como debe ser. Cabe mencionar que algunas historias orales que cuentan los habitantes del municipio, con relación a la educación, no concuerdan con la evidencia encontrada, por lo que el autor las tomó solamente como información adicional. La monografía contiene también, diversas fotografías históricas de escuelas y personajes que influyeron en la educación josefina. De manera que el desarrollo de esta monografía, propone brindar los hechos tal y como son para una mejor comprensión de la realidad educativa en el área urbana del municipio de San José La Arada, en un marco histórico, real y objetivo. Finalmente, el tipo de monografía utilizada en esta investigación fue documental histórica, pues se recopiló todos los registros históricos de cada institución educativa e instituciones relacionadas al tema y el instrumento utilizado para recabar la información fue la entrevista personalizada como apoyo para escribir las biografías de cada educador y sustentar los hallazgos encontrados en los archivos históricos

    Background Diabetes mortality at the United States–Mexico border is twice the national average. Type 2 diabetes mellitus is increasingly diagnosed among children and adolescents. Fragmented services and scarce resources further restrict access to health care. Increased awareness of the incidence of disease and poor health outcomes became a catalyst for creating community-based coalitions and partnerships with the University of Arizona that focused on diabetes. Context Five partnerships between the communities and the University of Arizona were formed to address these health issues. They began with health promotion as their goal and were challenged to add policy and environmental change to their objectives. Understanding the meaning of policy in the community context is the first step in the transition from program to policy. Policy participation brings different groups together, strengthening ties and building trust among community members and community organizations. Methods Data on progress and outcomes were collected from multiple sources. We used the Centers for Disease Control and Prevention’s Racial and Ethnic Approaches to Community Health (REACH) 2010 Community Change Model as the capacity-building and analytic framework for supporting and documenting the transition of coalitions from program to policy. Consequences Over 5 years, the coalitions made the transition, in varying degrees, from a programmatic focus to a policy planning and advocacy focus. The coalitions raised community awareness, built community capacity, encouraged a process of “change in change agents,” and advocated for community environmental and policy shifts to improve health behaviors. Interpretation The five coalitions made environmental and policy impacts by engaging in policy advocacy. These outcomes indicate the successful, if not consistently sustained, transition from program to policy. Whether and how these “changes in change agents” are transferable to the larger community over the long term remains to be seen

    This work is intended to be of support and utility for the Ministry of Tourism in Mexico, so that they can build a future SWOT evaluation of tourist destinations. As well, for those who are interested in areas related to the topics presented in this handbook.It presents the development of incorporate indicators of the Priority Tourist Destinations and Magic Towns of Mexico, derived from Sectorial Project 242853 called Development of Information Systems for the Management of the Tourist Destinations of Mexico, where the analysis of the Project is detailed, until the Achievement of the technological innovation generated, through an Information System.Mexico is a country which has as one of its strengths, cultural and natural resources in each of its states, municipalities and localities. Customs, traditions, gastronomy, ceremonial centers, archeological zones, waterfalls, the abundance in flora and fauna; so describe each of its wonders. These resources require laws and regulations to protect and maintain them, to improve infrastructure, to be sustainable, and attractive to national and international tourism without being damaged or that the inhabitants of those places are benefited by the generation of jobs, social security among others. Balancing all the factors involved is an arduous task and requires studies such as those carried out by various governmental and educational institutions, the private sector among others. In the next work to be published called "Compendium of tourist indicators of priority tourist destinations and magical towns", the analysis of variables and indicators of Priority Tourist Destinations is analyzed, taking as reference various guidelines, standards and information sources as The National Development Plan (NDP) 2013-2018, Tourism Sector Program 2013-2018 (TSP), Identification of Tourism Potentials in Regions and Municipalities (Fascicle 8), Competitiveness Agendas of Mexico's Tourist Destinations, (IMCO), the World Economic Forum (WEF), the Alliance for Excellence in Tourism (EXCELTUR), ITESM, the Guide for Incorporation and Permanence of the Magic Towns of the Tourism Secretaríat (Sectur) with the analysis for the automation of the evaluation of the Magic Towns, INEGI, DATATUR, DENUE among others. As a result of this in-depth analysis, we reach a concentration of 2610 indicators, which are found in an indicator matrix, which can be structured in a hierarchy with a level three depth (Component, subcomponent, factor and indicator). It is necessary to reduce these indicators, so that they identify and select those that have the greatest impact on the observation of tourism development of the destination, taking into account the sustainability, competitiveness, potential and tourism performance of priority tourist destinations and magic towns. The selection of these indicators is done with an affinity diagram or K-J method (Kawakita Jiro), which allows SWOT analysis of the CAs of priority tourist destinations and magic towns and the matrix of the 2610 indicators. This work is intended to be of support and utility for the Ministry of Tourism in Mexico, so that they can build a future SWOT evaluation of tourist destinations.

    Objectives In lupus nephritis the pathological diagnosis from tissue retrieved during kidney biopsy drives treatment and management. Despite recent approval of new drugs, complete remission rates remain well under aspirational levels, necessitating identification of new therapeutic targets by greater dissection of the pathways to tissue inflammation and injury. This study assessed the safety of kidney biopsies in patients with SLE enrolled in the Accelerating Medicines Partnership, a consortium formed to molecularly deconstruct nephritis.Methods 475 patients with SLE across 15 clinical sites in the USA consented to obtain tissue for research purposes during a clinically indicated kidney biopsy. Adverse events (AEs) were documented for 30 days following the procedure and were determined to be related or unrelated by all site investigators. Serious AEs were defined according to the National Institutes of Health reporting guidelines.Results 34 patients (7.2%) experienced a procedure-related AE: 30 with haematoma, 2 with jets, 1 with pain and 1 with an arteriovenous fistula. Eighteen (3.8%) experienced a serious AE requiring hospitalisation; four patients (0.8%) required a blood transfusion related to the kidney biopsy. At one site where the number of cores retrieved during the biopsy was recorded, the mean was 3.4 for those who experienced a related AE (n=9) and 3.07 for those who did not experience any AE (n=140). All related AEs resolved.Conclusions Procurement of research tissue should be considered feasible, accompanied by a complication risk likely no greater than that incurred for standard clinical purposes. In the quest for targeted treatments personalised based on molecular findings, enhanced diagnostics beyond histology will likely be required

    Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
