Estudio del clima motivacional en 1º de ESO y sus implicaciones en las estrategias de aprendizaje utilizadas

Treball de Final de Grau en Psicologia. Codi: PS1048. Curs acadèmic 2014-2015El presente estudio tiene un doble objetivo, por una parte identificar y analizar el clima motivacional en el aula de 1º de la ESO del Instituto de Educación Secundaria de Betxí y por otra parte, relacionar este clima motivacional con las estrategias de aprendizaje de evitación y con la satisfacción de los estudiantes en las asignaturas instrumentales de Lengua y Matemáticas. Concretamente queremos probar dos hipótesis. La primera pronostica que existe una relación positiva y significativa entre los Factores motivacionales y la satisfacción obtenida por los estudiantes, tanto en el proceso seguido, como en su progreso de enseñanza/aprendizaje, mientras que la segunda hipótesis pronostica una relación negativa y significativa entre Factores motivacionales y estrategias de aprendizaje de evitación utilizadas por los alumnos/as. La muestra está formada por 90 alumnos, y el análisis se ha realizado a partir de dos cuestionarios, basados en el Modelo de Calidad Situación Educativa (MCSE) propuesto por Doménech (2006, 2007,2011a, 2011b, 2012). Tras la obtención de los resultados y su posterior tratamiento estadístico, podemos afirmar que existe relación entre los Factores Motivacionales (estrategias docentes motivadoras e interacción profesor/contenido/alumno), las estrategias de aprendizaje evitación y la satisfacción, que permiten afirmar/constatar/determinar que exista un clima motivacional favorable en la situación educativa estudiadaThe objective of the current study was, on the one hand, to identify and analyse the motivational classroom climate in the 1st level/grade of ESO at the High School in Betxí, and, on the other hand, relating the classroom climate with the learning avoidance and the students´satisfaction in the instrumental subjects of Language and Mathematics. Specifically we tested two hypotheses. The first predicts that there is a positive and significant relationship between the motivational factors and students`satisfaction, both in teaching/learning process followed and in the progress obtained by students. The second hypothesis predicts a negative and significant relationship between motivational factors and the avoidance learning strategies used by students. The sample is composed of 90 students and the analysis was carried out from two questionnaires based on the Quality Model Educational (MQES) created by Doménech (2006, 2007, 2011a, 2011b, 2012) were administered. The results obtained from the statistical analyses performed indicated that there is a relationship between the motivational factors (motivational strategies of the teacher and teacher/contents/students interaction), learning avoidance strategies and students´satisfaction, it allows to assert/verify/identify there is a positive motivational climate in the educational situation studied

Organizational climate management based on leadership style on a Regional Council Interuniversitario university of north (CRI - North) - 2014

Se considera el clima organizacional como aquellas características del medio ambiente laboral que tienen repercusiones en el comportamiento personal, profesional, regula los factores del sistema organizacional y la influencia que ejerce el estilo de liderazgo que gestiona la universidad. La universidad como organización compleja, pues en ella participan diversos estamentos, genera una diversidad de observaciones y un sinfín de percepciones de cómo los miembros de la organización se interrelacionan entre si y cómo los que dirigen y gestionan la universidad ejercen su capacidad de conducción de sus colaboradores. El propósito de este artículo es dar cuenta de los hallazgos de la investigación desarrollada donde se diagnosticó la interrelación entre liderazgo y clima organizacional en una universidad del Consejo Regional Interuniversitario del Norte (CRI - norte) considerando la información proporcionada por los distintos estamentos que la componen: Directivos, docentes, estudiantes, personal administrativo y personal de Apoyo. El clima organizacional fue diagnosticado por un instrumento que medía tres dimensiones con veintinueve indicadores aplicado a cada estamento universitario. En tanto el estilo de liderazgo se diagnosticó con un instrumento que evaluaba tres estilos con veinte indicadores. La información recabada y analizada permitió arribar a la conclusión de que dicha universidad se gestiona siguiendo un estilo de liderazgo de tipo Laissez-Faire, generando con ello un clima organizacional percibido en forma mayoritaria en su dimensión participativa pero a un nivel medio.Abstract : The organizational climate as those characteristics of the working environment that impact on personal behavior, is considered professional, regulates the organizational system factors and the influence of leadership style that manages the university. The university as a complex organization, as various bodies involved in it, generates a variety of observations and endless perceptions of how members of the organization interact with each other and how to direct and manage the university exercised its ability to conduct its al. The purpose of this article is to report the findings of research carried out where the relationship between leadership and organizational climate was diagnosed in a University of North Interuniversity Regional Council (CRI - North) considering the information provided by the various bodies that compose : Managers, teachers, students, administrators and support staff. The organizational climate was diagnosed by an instrument, which measured three dimensions with twenty indicators applied to each university establishment. While leadership style was diagnosed with an instrument that evaluated three different styles with twenty indicators. The information gathered and analyzed allowed to arrive at the conclusion that the university is managed following a leadership style laissez-faire type, thereby generating an organizational climate perceived majority interests in its participatory dimension but at a medium level

Pre-Election Poll Estimations in Mexico: In Search for the Main Sources of Error

In this paper we test different hypotheses that reflect some of the most common sources of estimation error in pre-election polls. We test for questionnaire design effects, sampling effects, interviewer effects, spiral of silence effects, and several contextual effects (such as the perception of safety or danger in a polling point in face-to-face polls). We analyze data from a state-level pre-election poll conducted in the State of Mexico on June 2011, two weeks prior to election-day. This poll included an embedded experiment about the placement of the voting question and recorded several contextual variables that allow us to test for different possible sources of estimation error. In addition, this paper offers a brief review of preelection polling in Mexico during the last two decades, evaluating the polls’ performance in both national and state-level elections. This analysis is part (and certainly the first formal step) of a larger effort by polling firms and public opinion researchers, as well as by the Federal Elections Institute, to determine the most common causes of estimation error in Mexican pre-election polls.In this paper we test different hypotheses that reflect some of the most common sources of estimation error in pre-election polls.

Cortical development associated with conjugation of Paramecium

The cortical cytoskeleton of Paramecium is characterized by a complex, polarized and asymmetrical organization. In order to analyse the cortical development of Paramecium tetraurelia during the sexual process of conjugation, different antibodies have been used to follow the development of five cortical components: basal bodies, ciliary rootlets, outer lattice, epiplasm and cytospindle. This study demonstrates that the cortex of Paramecium undergoes an elaborate development process following conjugation. Some of the cortical structures that are not renewed at any other moment of the cell cycle, are resorbed after conjugation and replaced by other newly formed ones. The reorganization of the cortical components occurs according to different morphogenetic waves that spread over the cell surface. The oral system and the preoral suture line act as morphogenetic epicentres.Junta de Andalucía y Departamento General de Investigación Científica y Técnica (DGICYT) PB91/062

Relación entre perfil y visión emprendedora de los estudiantes universitarios

Entrepreneurship can be defined as the execution of a project or purpose where the person is fully prepared to take the risk and carry out the project. In Peru, business entrepreneurship is highly recognized, at the Latin American level, it is the first country with the highest perception, in relation to the simplicity when starting a business; and the third with respect to the faculties and competencies, as well as with greater possibilities for the citizen to become an entrepreneur. The present study determines the relationship between the entrepreneurial profile and the entrepreneurial vision of university students. The research is developed under a quantitative approach with a descriptive correlational scope, the sample was represented by 135 students enrolled in the faculty of business sciences of the Program of Study Administration and Human Resources of the Continental University in the academic cycle 2022- 2. A Pearson correlation coefficient of 0.78 was obtained, which indicates that there is a positive correlation between the variables of the study, such as theentrepreneurial profile and the entrepreneurial vision of university students. This proves the research hypothesis: the entrepreneurial profile has a positive correspondence with the entrepreneurial vision of the students of the faculty of business sciences of the Program of Study Administration and Human Resources of the Universidad Continental in the academic cycle 2022- 2.El emprendimiento puede definirse como la ejecución de un proyecto o propósito donde la persona se encuentra totalmente preparada para arriesgarse y efectuar el proyecto.

A soil quality index to evaluate the vermicompost amendments effects on soil properites

502-510The aims of this work were 1) to evaluate the changes in soil properties with the application of different amounts of vermicompost (10 and 20 Mg·ha–1), and 2) to construct a soil quality index that allows the evaluation of changes in the most sensitive soil parameters. The study was carried out in a cattle field of General Alvear, Buenos Aires, Argentina. Vermicompost application showed a positive effect on most of the chemical and biological soil properties evaluated, especially with the higher dose (20 Mg·ha–1). There were slight but significant increases in electrical conductivity and soil pH with the higher dose of vermicompost. Physical soil properties were not affected by the vermicompost amend-ment. The SQI showed a significant increase of soil quality with the vermicompost dose of 20 Mg·ha–1, especially by enhancing the biochemical and biological properties

Synthesis of IAN-type N,N-Ligands via Dynamic Kinetic Asymmetric Buchwald-Hartwig Amination

The Pd-catalyzed coupling of racemic heterobiaryl bromides, triflates, or nonaflates with aryl/alkyl primary amines using QUINAP as the ligand provides the corresponding axially chiral heterobiaryl amines with excellent yields and enantioselectivities. Reactivity and structural studies of neutral and cationic oxidative addition intermediates support a dynamic kinetic asymmetric amination mechanism based on the labilization of the stereogenic axis in the latter and suggest that coordination of the amine to the Pd center is the stereodetermining step.Ministerio de Ciencia e Innovación CTQ2013-48164-C2-1-P, CTQ2013-48164-C2-2-P, RYC-2013-12585 for A.R.European FEDER FundsJunta de Andalucía 2012/FQM 1078

Inhibition of hepatitis C virus internal ribosome entry site-mediated translation by an RNA targeting the conserved IIIf domain

Hepatitis C virus (HCV) translation initiation depends on an internal ribosome entry site (IRES). We previously identified an RNA molecule (HH363–10) able to bind and cleave the HCV IRES region. This paper characterizes its capacity to interfere with IRES function. Inhibition assays showed that it blocks IRES activity both in vitro and in a human hepatoma cell line. Although nucleotides involved in binding and cleavage reside in separate regions of the inhibitor HH363–10, further analysis demonstrated the strongest effect to be an intrinsic feature of the entire molecule; the abolishment of either of the two activities resulted in a reduction in its function. Probing assays demonstrate that HH363–10 specifically interacts with the conserved IIIf domain of the pseudoknot structure in the IRES, leading to the inhibition of the formation of translationally competent 80S particles. The combination of two inhibitory activities targeting different sequences in a chimeric molecule may be a good strategy to avoid the emergence of resistant viral variants.This work was supported by grant BFU2006-02568 from the Spanish Ministerio de Educación y Ciencia and CTS-233 from the Junta de Andalucía to A.
