Uso de Redes Sociales en asignaturas de Grado de Dirección de Recursos Humanos

El uso de las redes sociales online ha crecido vertiginosamente en los últimos años, y los jóvenes son los principales protagonistas de esta tendencia. Inmersos y educados y criados en medio de la tecnología, la nueva generación de estudiantes son nativos digitales. Los profesores, en cambio, somos inmigrantes digitales, pero tenemos la responsabilidad de convertir una tecnología que puede ser una distracción en una herramienta de enseñanza. Facebook es un ejemplo de tecnología Web 2.0 que tiene un enorme potencial en el campo de la educación, aunque no fue creada para construir o manejar experiencias de aprendizaje. Opera en una plataforma abierta, a diferencia de otros sistemas organizados alrededor de cursos estructurados formalmente. De hecho, aunque Facebook no es un entorno de aprendizaje, puede servir como un soporte muy valioso para las nuevas orientaciones sociales que aparecen ahora en los procesos educativos. El objetivo del presente trabajo es mostrar nuestra experiencia docente, en las asignaturas de grado de Dirección de Recursos Humanos, en la Universidad de Alicante, con la red social Facebook, obteniendo conclusiones y recomendaciones para mejorar el uso de redes sociales en la enseñanza universitaria.

DUENDE: Docencia Universitaria en Dirección de Empresas

El uso generalizado de Facebook como red social en la que compartir opiniones, información y recabar amistad o apoyo está introduciéndose también en el ámbito docente, ya que se puede ayudar a los estudiantes en el transcurso de las asignaturas, compartir información entre compañeros, notificar eventos de interés para la materia de estudio, etc. En esta memoria se expone nuestro trabajo con la red Facebook en asignaturas de grado, que ya comenzó el curso pasado. Se trata de contrastar si las conclusiones obtenidas en el pasado curso se reafirman o no para extraer recomendaciones que orienten el uso de Facebook como herramienta de enseñanza/aprendizaje.

Dirección Estratégica y Diseño Organizativo. Curso Académico: 2014-2015

Esta red inicia su andadura en el presente curso académico con la intención de mejorar la docencia en las asignaturas que la integran. En la presente edición la red se ha preocupado por actualizar y mejorar las actividades docentes y de evaluación continua en las asignaturas “Dirección Estratégica de la Empresa I” y “Dirección Estratégica de la Empresa II”, impartidas ambas en el tercer curso del grado en ADE y en el cuarto de DADE y TADE. La evolución desfavorable que ha supuesto el aumento considerable del número de alumnos por grupo, junto a otras circunstancias detectadas por los profesores de las asignaturas, han aconsejado eliminar la resolución y defensa de casos largos (método del caso), tanto en el desarrollo de las clases prácticas como en la evaluación continua. A partir del curso próximo, las clases prácticas se sustentarán, principalmente, en la resolución y discusión de casos breves. Este método, junto a la realización de un control escrito, constituirán las principales actividades de evaluación continua.

Patronazgo nobiliario e individuo. Los Macanaz y la “hora” del XVIII

Desde la fecunda obra de Caro Baroja, la renovación de las élites de gobierno localizada a comienzos del setecientos ha llamado la atención de una parte de la historiografía preocupada en proponer diversos enfoques con los que interpretar este proceso de enormes consecuencias sociales y políticas. El caso de los Macanaz presenta una serie de peculiaridades que lo hacen propicio para un análisis detallado de su proceso de promoción familiar en el que sobresale la trascendencia de ciertos factores escasamente subrayados hasta el momento. El importante papel desempeñado por la casa aristocrática de Villena y el escaso peso de lo local o regnícola en su proyección posterior, nos servirá para cuestionar la dimensión de los Macanaz como iniciadores de una hipotética “hora murciana”, destacando en su caso la importancia de otros elementos complementarios como el patrocinio nobiliario, el mérito, la formación y la capacidad e iniciativa individual, vías también de acceso al servicio del rey.

Efecto de las promociones del precio sobre la venta de productos no promocionados:papel moderador del tipo de visita del cliente

Pese a la importancia de cuantificar el efecto de las promociones del precio sobre la venta de productos no promocionados, la evidencia empírica existente en esta área es escasa y poco concluyente. El presente trabajo analiza el efecto simultáneo de todas las promociones del precio llevadas a cabo por el minorista sobre la venta de productos no promocionados, teniendo en cuenta el papel moderador del tipo de visita que lleva a cabo el cliente al establecimiento. Los resultados de este trabajo revelan que las promociones del precio estimulan la venta de productos no promocionados, pero que la fuerza de este estímulo depende del tipo de visita y de si la promoción del precio es anunciada o no en el folleto del minorista. En concreto se evidencia que la magnitud del efecto es mayor para los clientes que llevan a cabo una visita especial y cuando las promociones del precio son anunciadas en el folleto publicitario del minorista.

Estudo de arranjos de antenas de microfita com Patch quase-fractal para comunicações sem fio

In this dissertation, are presented two microstrip antennas and two arrays for applications in wireless communication systems multiband. Initially, we studied an antenna and a linear array consisting of two elements identical to the patch antenna isolated. The shape of the patch used in both structures is based on fractal geometry and has multiband behavior. Next a new antenna is analyzed and a new array such as initial structure, but with the truncated ground plane, in order to obtain better bandwidths and return loss. For feeding the structures, we used microstrip transmission line. In the design of planar structures, was used HFSS software for the simulation. Next were built and measures electromagnetic parameters such as input impedance and return loss, using vector network analyzer in the telecommunications laboratory of Federal University of Rio Grande do Norte. The experimental results were compared with the simulated and showed improved return loss for the first array and also appeared a fourth band and increased directivity compared with the isolated antenna. The first two benefits are not commonly found in the literature. For structures with a truncated ground planes, the technique improved impedance matching, bandwidth and return loss when compared to the initial structure with filled ground planes. Moreover, these structures exhibited a better distribution of frequency, facilitating the adjustment of frequencies. Thus, it is expected that the planar structures presented in this study, particularly arrays may be suitable for specific applications in wireless communication systems when frequency multiband and wideband transmission signals are required.

Projeto de absorvedores de micro-ondas integrados com superfícies seletivas em frequência

Considering the fact that, the use of wireless communication systems has grown too fast, investigations concerning absorbers of electromagnetic waves has called closer attention of researchers. It is applicable from indoor systems to military applications. Paralleling with this growth, some extremely relevant investigations through Frequency Selective Surfaces (FSS) allows its filter property to be applicable in several systems, for example: reflector antennas, band-pass radomes, and absorbers, which are the main objective of this work. Therefore, the main goal of this work concerns to design micro-waves absorbers through FSS. Thus, the methodology consists basically in two steps: the first step concerns a theoretical and numerical analysis of the structures involved in the process of absorption, the second step, the analysis of the cascaded structures. In order to carry out the analysis, the Equivalent Circuit Method will be used. This method provides characteristics of transmission from the structure, for a plane wave incidence and it requires an extremely limited computing resource in relation if compared to full wave analyses method. Hence, it is useful to allow fast predictions of the development of the structures. Furthermore, a spreading matrix will be used in order to cascade the conductive FSS and the resistive FSS achieving absorption characteristics in the designed band. The experimental results used for the analysis are found in the literature due to the difficulty of building soon, given that it is not a simple construction technique. To conclude, a mathematical development through the Equivalent Circuit Method of a FSS modeling with cross-dipole geometry and a resistive FSS will be presented, as well as the cascading involving the two structures. The same setting is used with a square loop geometry. Besides it, the next steps will be discussed in the conclusion.

Bi anisotropia em antenas de microfita retangular e estruturas circulares modificadas

The microstrip antennas in your simplest form consist of a ground plane and a dielectric substrate which supports a conductive tape. As these antennas have some limitations, this work presents a study of anisotropic substrates, as well as some results in microstrip antennas with circular patch, aiming to overcome these limitations, especially in applications at 4G technology. These anisotropic substrates are those in which electrical permittivity and magnetic permeability are represented by tensors of second order. The study consists of a theoretical analysis of substrates and development of a mathematical formalism, the Transverse Transmission Line Method, aimed the application of these substrates in microstrip antennas. Among the substrates used in this study, there are the ferrimagnetic and metamaterials, in which some miniaturizations of the antennas are achieved. For antennas with circular patch, are considered arrays and modified ground planes in order to achieve improvement in parameters, in particular, gain and bandwidth. Several simulations have been made and antennas were constructed so that the measured values could be compared with the simulated values.

Implementação de conversor de polarização linear-circular para antenas de microfita usando metasuperfícies

This work aims to propose a new model of metasurface with simplified basic cell, able to convert linearly polarized signals generated by planar antenna array in circularly polarized signals, for the ISM frequency band (2.45 GHz), with good bandwidth of return loss and axial ratio. To study the behavior of the proposed structure, the metasurface is coupled to three different structures. First, initial tests are made with the metasurface coupled to a microstrip antenna in its simple configuration. Then the metasurface is coupled to an array with two elements of patch type. And later it is coupled to an optimized array, that uses a stub in its main feed, to get a better impedance matching. The structures are analyzed numerically through Ansoft HFSS™, and to validate these results, the structures are characterized experimentally. The characteristics of transmissions simulated and measures are presented. A good agreement between simulated and measured results was obtained. The structure proposed here has the advantage of meeting the desired characteristics, with a simple geometry to be built using a low-cost substrate (FR-4).

Método híbrido para projeto de superfícies seletivas em frequência

This thesis presents a hybrid technique of frequency selective surfaces project (FSS) on a isotropic dielectric layer, considering various geometries for the elements of the unit cell. Specifically, the hybrid technique uses the equivalent circuit method in conjunction with genetic algorithm, aiming at the synthesis of structures with response single-band and dual-band. The equivalent circuit method allows you to model the structure by using an equivalent circuit and also obtaining circuits for different geometries. From the obtaining of the parameters of these circuits, you can get the transmission and reflection characteristics of patterned structures. For the optimization of patterned structures, according to the desired frequency response, Matlab™ optimization tool named optimtool proved to be easy to use, allowing you to explore important results on the optimization analysis. In this thesis, numeric and experimental results are presented for the different characteristics of the analyzed geometries. For this, it was determined a technique to obtain the parameter N, which is based on genetic algorithms and differential geometry, to obtain the algebraic rational models that determine values of N more accurate, facilitating new projects of FSS with these geometries. The optimal results of N are grouped according to the occupancy factor of the cell and the thickness of the dielectric, for modeling of the structures by means of rational algebraic equations. Furthermore, for the proposed hybrid model was developed a fitness function for the purpose of calculating the error occurred in the definitions of FSS bandwidths with transmission features single band and dual band. This thesis deals with the construction of prototypes of FSS with frequency settings and band widths obtained with the use of this function. The FSS were initially reviewed through simulations performed with the commercial software Ansoft Designer ™, followed by simulation with the equivalent circuit method for obtaining a value of N in order to converge the resonance frequency and the bandwidth of the FSS analyzed, then the results obtained were compared. The methodology applied is validated with the construction and measurement of prototypes with different geometries of the cells of the arrays of FSS.
