Skills acquisition in Tourism Degree through case-based learning

The labor market requires professionals with skills that go beyond the contents of the curriculum itself, the so-called key or cross curricular skills. This implies that those involved in the teaching-learning process of students must develop teaching methodologies that enable the appropriate acquisition of those skills. This paper aims to analyze whether the case study favors the development of generic skills more than traditional methodologies. This methodology has been applied to courses of Applied Economics taught in the Tourism Degree at the University of Jaen. Thus, by using inferential statistics applied to a sample of students divided into two groups (control group: those who were taught using traditional teaching methods; experimental group: those who have used case studies as their teaching methodology). The results obtained support that there are significant differences regarding the acquisition of key or cross curricular skills depending on the teaching methodology used. Therefore, the experience described here provides evidence that case study methodology could improve the acquisition of cross curricular skills by students taking the Tourism Degree at the University of Jaen.

El Consumo de Drogas en el Alumnado de la Universidad de Jaén [The drug use in students from the University of Jaen

In recent years, the consumption data of psychoactive substances among young people have increased (WHO, 2011). Therefore, the objectives of this study were know the current status of drug use among consumer groups and high-risk alcohol and tobacco. A descriptive and cross-sectional study based on a survey was conducted, in a sample of 303 university students from the University of Jaen. The results indicate an increase of psychoactive substances over the years and that alcohol and tobacco seem to favor the intake of other psychoactive substances in university population. So it is necessary to continue working on awareness and establish improvements in preventive actions in the university context, in order to reduce as far as possible the effects of consumption.

A Methodology to Obtain Learning Effective Laboratories with Learning Management System Integration

Online laboratories are useful and valuable resources in high education, especially in engineering studies. This work presents a methodology to create effective laboratories for learning that interact with a Learning Management System (LMS) to achieve advanced integration. It is based on pedagogical aspects and considers not only the laboratory application itself but also related resources that complement it. The methodology is flexible, covers all possible cases, and it is structured in stages that can be used with any system architecture, standards, or type of online laboratory (virtual, remote, or hybrid) because it abstracts technical aspects at a high level. This methodology facilitates the creation of new online labs so that any teacher, even those without specialized knowledge, can clarify many of the questions that may arise and gain understanding of how to implement an effective online laboratory with LMS integration to assist learning. As an example and validation of the methodology, this work describes a laboratory developed as a Shared Content Object Reference Model (SCORM) package which is hosted in the institutional LMS at the University of Jaen. The laboratory was presented to 338 students taking an Industrial Automation class, and student evaluations were quite positive.

Conocimientos y actitudes sobre sexualidad en adolescentes de primer curso de Grado en Educación Infantil y Primaria de la Universidad de Jaén

Objetivo: Conocer los conocimientos y actitudes sobre sexualidad en los adolescentes de primero de Grado en Educación de la Universidad de Jaén.<br /><br />Material y Método: Los datos se recogieron a través de un cuestionario anónimo, voluntario y autocumplimentado, el cual se aplicó a una muestra no probabilística por conveniencia de 151 sujetos estudiantes de primer curso de Grado en Educación Infantil y Primaria de la Universidad de Jaén.<br /><br />Resultados: 118 manifiestan haber mantenido relaciones sexuales con penetración, siendo estas diferencias significativas entre chicas y chicos (p=.034), al igual que para la masturbación en cuanto al sexo (96% de los hombres frente a 19% de las mujeres). También son las mujeres las que practican más el fellatio (p=.031), pero estas prácticas sexuales las realizan con la pareja (p=.01), siendo los chicos los que presentan mayor consumo de alcohol previo al coito (p=.021) y mayor número de parejas sexuales (p=.026). Siguen siendo ellas las que identifican en mayor proporción el papiloma como ITS (p=.02). Y el 27,7% del total conocen el doble método anticonceptivo.<br /><br />Conclusión: Tres cuartas partes de la muestra han mantenido relaciones coitales haciendo uso de anticonceptivos para evitar el embarazo. Valorando esto junto con un escaso conocimiento del doble método (una cuarta parte del total) y de las infecciones de transmisión sexual, nos lleva a pensar como materia necesaria la educación sexual para estos adolescentes.

Advanced LMS Integration of SCORM Web Laboratories

E-learning and its hybrid counterpart—B-learning—have become standard tools in higher education. The development of information and communications technologies (ICTs) and their application to education has made this possible. Among ICT technologies, the learning management system (LMS) has been the most important development. Teaching labs have also undergone a technological evolution, enabling them to be used online while interacting closely with LMSs. This paper presents a set of procedures that ease the integration of Java and JavaScript laboratories with LMSs in order to obtain adaptive learning contents, which are presented customized to students based on their likes and results. It describes innovative tools implemented by us as a Java package, a JavaScript library, and associated resources that achieve an advanced Lab-LMS integration in a shared content object reference model (SCORM) environment. These resources simplify communications between the elements of an SCORM content package, including the embedded Web laboratory, and the LMS where they are hosted. This paper describes the tools, procedures, and discusses its possibilities and advantages, and shows the results of several use cases of Web Labs delivered to undergraduate engineering students at University of Jaen that prove the validity of the proposal obtaining adapted learning and good results.

Model for estimating the energy yield of a high concentrator photovoltaic system

The prediction of the energy yield of HCPV (high concentrator photovoltaic) systems is crucial to evaluate the potential and promote the market expansion of HCPV technology. Currently, there is a lack of experience in the modelling of these kinds of systems due to the special features of such technology. In this work, a practical model based on simple mathematical expressions and atmospheric parameters is introduced. The proposed model takes into account the main important parameters which influence the output of a HCPV system such as cell temperature, spectrum and efficiency of the inverter and other losses of the BOS (balance of system). The results obtained are validated using the data of a HCPV installation located at the University of Jaen in southern Spain and monitored daily every minute since 2011. The model accurately predicts the monthly energy yield with a deviation ranging from 4.07% to −0.47% and the annual final energy yield with a deviation of 0.9%.

Sarcobesity and osteoporosis

s / Maturitas 81 (2015) 105–121 113 Finally, additional factors related to older individuals, specifically cognitionand emotion-based features that can impact falls risk are discussed as related to their importance for consideration in routine falls assessments. This speech summarizes information to help guide the clinician in choosing themost appropriate currently available tool. Asmany of thesemeasures are similar in their sensitivity and specificity, decisions on which approach to take in many casesmayhave to be informedalso by the clinic setting andexisting resources available to the clinician. http://dx.doi.org/10.1016/j.maturitas.2015.02.037 INV26 Sarcobesity and osteoporosis Fidel Hita Contreras1,∗, Antonio Martinez Amat1, David Cruz Diaz1, Faustino R. Perez-Lopez2 1 University of Jaen, Health Sciences, Jaen, Spain 2 University of Zaragoza, Faculty of Medicine and Lozano Blesa University Hospital, Zaragoza, Spain In the last decades, overall survival has drastically increased. Contrary to the decrease in muscle and bone tissue, fat tissue accumulation increaseswith agingup to a certain age.Whereas sarcopenia, an age-related loss of muscle mass and physical function, and sarcopenic obesity have been widely spread and recognized, the addition of decreased bonemass to these entities is a relatively recent concept. These are threemultifactorial conditions which are interrelated and share common pathophysiological factors. Whether considered as separate entities or as a single one, which is termed osteosarcopenic obesity, these involve an increased risk of diminished health-related quality of life, of medical complications and of reduced survival. It has been shown that these patients present poorer clinical outcomes, due to the cascade of metabolic abnormalities associated with these changes in body composition, as well as an elevated risk of disability, falls and fractures, which are some of the major causes of mortality and morbidity in older adults. There are still no well-defined criteria for its diagnosis, but we must consider the main cut-off points of the three pathologies involved. Since this is a complex condition, multifactorial management is likely to be the best approach. A combined strategy including an appropriate diet and nutrition, physical exercise, and pharmacological treatment may help not only treat the potential negative consequences of osteosarcopenic obesity, but also prevent its onset. http://dx.doi.org/10.1016/j.maturitas.2015.02.038 Psychosomatic and sexual medicine in routine practice

Redes sociales y formación permanente en personas mayores

Diversos factores sociodemográficos están haciendo que en nuestra sociedad nos encontremos cada día más con un grupo de población de personas mayores que se mantiene activa e inserta en la dinámica diaria. No obstante, se tiene la creencia de que existen determinadas barreras que hacen que este grupo de personas no se enfrente adecuadamente a las tecnologías y más aún a las redes sociales. La creación de los Programas Universitarios de Mayores (PUM), sin embargo, está dando lugar a un nuevo escenario, ya que las personas mayores que participan en ellos entran en contacto con contenidos de todo tipo y con el rigor y la actualización propios de las enseñanzas universitarias, modificando de esa manera la forma de afrontar las situaciones más novedosas y diferentes. En el presente estudio, pretendemos analizar cuál es el conocimiento y uso que las personas mayores, que asisten al PUM de la Universidad de Jaén, tienen de las redes sociales y la valoración que hacen de la necesidad de que en estos programas se impartan este tipo de contenidos. Para conseguir esto, se ha utilizado una metodología en la que se articulan procesos cualitativos y cuantitativos, a través del análisis de los datos obtenidos de entrevistas y un grupo de discusión con el programa Aquad 7. Los datos recogidos muestran que aún existe cierto desconocimiento sobre las redes sociales por parte de las personas mayores, pero que todos valoran su utilidad y necesidad. Los participantes consideran que ellos van a ser menos víctimas de los riesgos de estas tecnologías y demandan una mayor formación en estos contenidos dentro de los PUM.

Inteligencia emocional percibida, ansiedad y afectos en estudiantes universitarios = Perceived emotional intelligence, anxiety and affect on university students

ABSTRACT Perceived emotional intelligence (PEI), anxiety and affect become especially relevant among the teaching staff during the initial training period. The main purpose of this study aims to check the links between PEI, anxiety and affect, detect any significant differences depending on the socio-demographic indicators taken into consideration (gender, age and academic qualification), as well as predicting which indicators could be considered in measuring trait anxiety. The sample is made up of 325 students at the University of Jaen (Spain) involved in teaching degree programmes. The tools deployed consisted of a socio-demographic questionnaire (gender, age and academic qualification), the Trait Meta-Mood Scale 24 –TMMS 24- (Fernandez-Berrocal, Extremera and Ramos, 2004), the State-Trait Anxiety Inventory –STAI- (Spielberger, Gorsuch y Lushene, 1970; 2008), as well as the PANASN Scale of positive and negative affect (Sandin, 2003). Significant differences (p<.01) have been obtained in some instrument dimensions depending on the socio-demographic variables taken into consideration (gender, age and academic qualification), as well as important correlations between the instrument scales (p<.05; p<.01). Finally, similar results were obtained both for men and women as regards the most reliable variables predicting trait anxiety in the lineal regression analysis carried out by using the stepwise regression method, negative affect resulting the most important variable concerning women, while the dimension “perception of PEI” resulted the most influential one with reference to men; in both cases, these variables proved the most relevant to ensure predictability. The achieved results relate to those obtained in other studies implemented in similar contexts.

PROTOTIPO EXPERIMENTAL DE UNA MARQUESINA DE APARCAMIENTO DISEÑADA PARA OPTIMIZAR LA RECARGA DE VEHÍCULOS ELÉCTRICOS

On this article is described the experience on the design, calculation and construction of an experimental prototype of a parking canopy with a photovoltaic charger installed on the roof and with capacity for four vehicles. Additionally, the a charging point has been installed. The location selected has been the laboratory of energy of ADIF, in Madrid, and is the result of the collaborative work of AFFIRMA and ANDELSA companies and researches of the University of Jaen. The study include different phases. First has been calculated the solar gain according to the tracking system selected. From the beginning of the project was rejected the possibility of an additional degree of freedom (corresponding with the roof canopy inclination), because the solar gain is very little in comparison with the additional complex mechanical and structural system required. The mechanism that provides the selected movement can be installed on the available space, and a electric linear actuator fixed on columns supplies the necessary force. Finally the structure has been calculated for the selected emplacement. A versatile design has been carried out, so the installation can be projected for any location by the only implementation of minimal adaptations.

Valoraciones del alumnado del grado de Educación Infantil

Esta investigación pretende analizar las percepciones del alumnado del Grado de Educación Infantil de la Universidad de Jaén acerca del Espacio Europeo de Educación Superior (EEES); asimismo, se pretende examinar si la titularidad del centro de Educación Superior así como el nivel educativo en que se encuentra el alumnado influye en sus valoraciones sobre el proceso de convergencia europea. Para ello, se ha utilizado un método descriptivo llevándose a cabo la recogida de datos mediante un cuestionario ad hoc al que se ha revisado su validez y confiabilidad (n = 361). El análisis de datos se ha llevado a cabo mediante el paquete informático Statistickal Package for Social Sciences (v. 19), realizándose un análisis descriptivo básico para cada uno de los ítems que componen cada factor de la escala así como una prueba t de Student de diferencia de medias para las variables sociodemográficas estudiadas. Los resultados obtenidos demuestran cómo los estudiantes del Grado de Educación Infantil de la Universidad de Jaén se muestran satisfechos con la labor desarrollada por el profesorado, a pesar de considerar que el nuevo plan de estudios no facilita el desarrollo de un proceso de enseñanza y aprendizaje de calidad. Los estudiantes muestran desconocimiento ante el crédito europeo, resultados de aprendizaje, aspectos académicos y, en general, hacia el nuevo plan de estudios. Además, es el alumnado que cursa sus estudios en la Universidad de Jaén (de titularidad pública) y los matriculados en el primer curso del Grado los que presentan una valoración más positiva hacia la propia institución y el EEES.

Grid parity and self-consumption with photovoltaic systems under the present regulatory framework in Spain: The case of the University of Jaén Campus

Abstract The cut-off of any subsidy or feed-in tariff that incentives the installation of new renewable energy systems which are close to the grid parity, is a reality in most of the European countries, but in the recent years the grid parity has worsened because of the global economic crisis. In the case of Spain, in addition to the economic problems, the photovoltaic sector has been dramatically damaged through a changeable regulatory framework, an excessive bureaucracy and the inclusion of additional fees or possible back-up tolls that are very prejudicial for the deployment of this sector. Nowadays, the current Spanish legislation mentions the possibility of self-consumption (totally or partially) of the electricity generated by PV or any renewable energy systems but, up to the date of this work, the law that regulates the administrative, technical and economic conditions for the net-metering of the electrical energy produced within the consumer׳s network, is still under a draft stage. In this paper it is analyzed the case of the University of Jaen, where it has been identified and simulated several PV systems on the roofs and parking lots of the University Campus, and considering the current electrical tariffs (hourly defined for the case of high power and high voltage consumers), it has been done a cost and economic analysis. As a result, it has been obtained an average Levelised Cost of Energy around 0.125 € kWh −1 , a discount payback time of 17.5 years or less, a positive Net Present Value and a nominal Internal Rate of Return of 8.48% in the worst case. Beyond that, it has been carried out a sensitivity analysis of the factors that have more influence in the profitability of these systems, like the initial investment cost, the PV electricity yield, additional taxes and the variations in the electricity price market.

Online Exportation of Olive Oil: New Challenges

This study is part of the Research Project of Excellence, awarded to the University of Jaen (Spain) by the Ministry of Innovation and Science of Andalusia: Cod. AGR – 5961: “Strengths and weaknesses in the internationalization of the olive oil sector in Jaen province: The case of small and medium enterprises”. Throughout the study methodology used in the design of the website www.yoexportoaceite.com is taken into account. The website collects information and resources to be used as a guide by the small and medium olive oil enterprises (SMEs) in the process of internationalization, as well as a Pilot on-line Store. However, there are still a number of difficulties facing the user of the Virtual Store for the exportation of olive oil, arising from, among other reasons, the absence of a uniform set of regulations governing the formation of an international electronic contract, especially in the European Community area.
