WAGE GAPS AND MIGRANTION COSTS: AN ANALYSIS FROM SIMULATION DATA

Borjas (1987, 1991 and 1994) developed the self-selection theory, applying Roy’s model (1951) to migration studies. He establishes that the characteristics of migrants in terms of skills and abilities are driven by wage distribution differences between the host country and home. In this regard, when the country of origin has higher relative returns for skills and more disperse income distribution, a negative selection of migrants is generated, and vice versa. A great deal of literature has studied Self-selection model to analyse how wage distribution influences migrants’ decisions, leading to consistent and inconsistent results. Given the conflicting results in the literature, this paper examines how migration costs and wage differences influence self-selection patterns –i.e. skills in terms of schooling levels. Taking into account that self-selection can not be studied systematically by means of standard data sources because of the lack of data, we propose an analytical model based on the individual investment decision theory (Human Capital theory), applying simulated data by Monte-Carlo method. The theory of individual investment decisions allows us to analyze self-selection patterns across differences in wages and economic conditions at home and in host countries and to introduce uncertainty using a stochastic framework. An empirical application for long-distant migrations –from Ecuador to Spain– is implemented. Our findings show that migrants are positively selected on observable skills between Spain and Ecuador, considering both constant direct migration costs and constant direct migration costs-plus-variable opportunity migration costs. Secondary data from official sources confirm this tendency.

Scientific Computing and the Huygens' Principle

Abstract. Mathematics has been present in the development of society since time immemorial; great figures have dedicated their entire life to analysis and research in various branches of this broad science. Scientific Computing is closely related to the design and construction of mathematical models aimed at solving scientific, social and engineering problems. There are several applications of this discipline, for example for mathematical simulations of differential equations in partial derivatives that describe the propagation of a variety of waves such as sound waves, or heat conduction problems in different media, which can be solved using The Fourier Analysis. Through Graphical Computing the Huygens Principle can be verified. All these models can be implemented through the computer in order to facilitate the complex calculations that must be done to solve problems of this type and depending on the case to condense all this information into a graph "A good graph says more than a thousand words (Chinese Proverb) ". 

REPERCUSIÓN DE LA CALIDAD DE LA ATENCIÓN ODONTOLÓGICA EN LA SATISFACCIÓN DE LOS PACIENTES DEL CENTRO DE SALUD INDEPENDENCIA AREQUIPA 2013

El presente trabajo de investigación tuvo como objetivo mejorar la calidad de atención de los pacientes en el Centro de Salud Independencia con el fortalecimiento y desarrollo de las capacidades y competencias del personal tanto asistencial como administrativo, dicho Establecimiento de Salud se ubica en el distrito de Alto Selva Alegre y forma parte de la Microrred Alto Selva Alegre de la Red de Salud Arequipa Caylloma. La hipótesis fue comprobada, encontrándose que la calidad de la atención Odontológica y la Satisfacción del paciente fue de moderada a buena según la escala de valor – Coeficiente de correlación de Spearman. Metodología: Se aplicó la técnica de entrevista estructurada aplicándose una ficha de investigación, se aplicó el coeficiente de correlación de Spearman Resultados: Fueron encuestados 114 pacientes, que se atendieron en el servicio de Odontología, en el mes de agosto 2013, encontrándose que el 68% proceden de la región Arequipa. Conclusiones: La calidad de atención odontológica en el Centro Salud Independencia con respecto al Proceso podemos decir que la credibilidad, la seguridad, el profesionalismo, la fiabilidad, la confidencialidad, la comunicación los elementos tangibles y la comodidad, así como en su Estructura en lo que respecta a el horario de atención, su ubicación, sus costos y su accesibilidad son adecuados. En cuanto a la satisfacción del paciente en el proceso y estructura se encontró que el trato recibido fue adecuado

Design, assembly and experimental tests of a Savonius type wind turbine

The present research project focuses on the development of a Savonius type wind turbine, where a literature review is initially carried out to recognize the appropriate parameters for its design such as turbulence, wind velocity, and air density, followed by a design methodology to achieve the dimensioning by means of resistance calculation and selection of component materials, after having the final concept defined. Using computational tools such as Solidworks, Inventor, Simulation Mechanical, the design stage was validated through simulation to study the dynamic fluid behavior and the components were modeled to evaluate their response to wind loads, verifying their resistance. Subsequently, according to the modeling, the detailed drawings of the components of the turbine were obtained, with which they were assembled. Finally, having the physical model of the Savonius wind turbine, experimental tests were carried out in the laboratory of Fluids and Hydraulic Machines of the Technological University of Pereira

Análisis del efecto Inhibitorio de Clorhexidina 0.12% y Peróxido de Hidrógeno 3% sobre las bacterias presentes en los cepillos dentales utilizados por Estudiantes de V Año de la Carrera de Odontología de la UNAN-Managua en el primer semestre del año 2017

Los cepillos dentales han sido usados para control de la higiene oral desde tiempos inmemoriales, estudios han mostrado que varios microorganismos pueden crecer en los cepillos de dientes después de su uso. Para controlar la contaminación de los cepillos dentales se han empleado diferentes métodos de descontaminación entre ellos la clorhexidina y el peróxido de hidrogeno. El objetivo del presente estudio, fue comparar los efectos inhibitorios de la clorhexidina al 0.12% y el peróxido de hidrogeno al 3% en el control de bacterias presentes en cepillos dentales utilizados por estudiantes de V año de la carrera de odontología de la UNAN-Managua. Para este estudio fueron seleccionados 30 estudiantes de 5to año la carrera de odontología de la UNAN-Managua, 15 de ellos tuvieron un almacenamiento libre de los cepillos dentales y los otros 15 utilizaron medio de almacenamiento (capuchón). Después de haber transcurrido 30 días se procedió a la recolección de los cepillos de dientes para la posterior inoculación de bacterias encontradas en dichos cepillos según medio de almacenamiento en los laboratorios de Microbiología de la UNAN-Managua. Se llegó a la conclusión de que ambas soluciones disminuyen la carga bacteriana en los cepillos dentales, sin embargo al comparar las soluciones desinfectantes, el peróxido de hidrogeno al 3% y la clorhexidina al 0.12%, no se encontraron datos estadísticamente significativos (P=0.59). Palabras Clave: Clorhexidina, Peróxido de Hidrogeno, Cepillos dentales, microorganismo

Tools for mixed-criticality partitioned systems: partitioning algorithm and extensibility support

The development of mixed-criticality virtualized multicore systems poses new challenges that are being subject of active research work. There is an additional complexity: it is now required to identify a set of partitions, and allocate applications to partitions. In this job, a number of issues have to be considered, such as the criticality level of the application, security and dependability requirements, operating system used by the application, time requirements granularity, specific hardware needs, etc. MultiPARTES [6] toolset relies on Model Driven Engineering (MDE) [12], which is a suitable approach in this setting. In this paper, it is described the support provided for automatic system partitioning generation and toolset extensibility
