Effects of Motivation, Basic Psychological Needs, and Teaching Competence on Disruptive Behaviours in Secondary School Physical Education Students

Currently, disruptive and aggressive behaviours of a physical and verbal nature are a reality among adolescent students and a concern in the educational context. Therefore, the main objective of this research was to analyse the effects of perceived teaching competence, motivation and basic psychological needs on disruptive behaviours in secondary school PE students. The sample was composed of 758 adolescent students from seven public secondary schools. The following instruments adapted to physical education were used: The Disruptive Behaviours Questionnaire, The Evaluation of Teaching Competencies Scale, The Sport Motivation Scale, and The Basic Psychological Needs Scale. Multilevel regression models with the MIXED procedure were performed for data analysis. The results show that misbehaviour is more likely among male students and that disruptive behaviours decrease when a teacher is perceived as competent. Students with greater self-determined motivation are more likely to exhibit fewer behaviours related to low engagement and irresponsibility while amotivation increases the different disruptive behaviours in the classroom. In conclusion, it is proposed that educators work in line with the students’ needs by responding to their interests and that this will increase self-determined motivation

Multivariate Statistical Analysis of Phyllite Samples Based on Chemical (XRF) and Mineralogical Data by XRD

It is presented the results obtained of a multivariate statistical analysis concerning the chemical and phase composition, as a characterization purpose, carried out with 52 rock phyllite samples selected from the provinces of Almería and Granada (SE Spain). Chemical analysis was performed by X-ray fluorescence (XRF). Crystalline phase analysis was performed by X-ray powder diffraction (XRD) and the mineralogical composition was then deduced. Quantification of weight loss (100° and 1000°C) was carried out by thermal analysis. The aims of this investigation were to analyze and compare the chemical and mineralogical composition of all these samples and to find similarities and differences between them to allow a classification. Several correlations between results of the characterization techniques have been also investigated. All the data have been processed using the multivariate statistical analysis method. The XRF macroelements (10) and microelements (39) data generate one macrogroup with two new subgroups (1 and 2), and an isolated sample. In subgroup 1 of macroelements, a positive correlation was found between XRF results and geographic location characterized by lower MgO content, which is associated to its geological origins. When multivariate statistical analysis is applied to results obtained by XRD, two groups appear: the first one with a sample with zero percentage of iron oxide and the second one with the rest of the samples, which is classified in two groups. A correlation is observed between the alkaline content (XRF) and illite (XRD), CaO and MgO with dolomite and indirectly between the weight loss after heating at 1000°C and the contents of phase minerals that lose structural water (illite + chlorite) or carbon dioxide (dolomite). The present investigation has interest and implications for geochemistry and analytical chemistry concerning earth rocks and silicate raw material

Viability of the Raw Cotton Production in Spain After the Decoupling of the Subsidies

Considering the latest reform of the EU's Cotton Regulation of 29th April 2004, which will come into force in the 2006/07 season, we analyse its impact on the cotton production sector of Andalusia. The decoupling of subsidies implies that producers will be entitled to 65 percent of the amount received in the reference period (three years) irrespective of the crop chosen to grow. The remaining 35 percent (slightly higher) is paid as cotton are a payment. In this research, first from a survey carried out in 2004 we obtained six groups of producers using fact or analysis and cluster analysis. Then, based on this characterization, we assess the impact of two policy scenarios: (a) the implementation of the reform without any additional measures, and (b) the addition of a complementary environmentally based area payment plus the modulation of the decoupled subsidy up to 50 percent according to raw cotton quality. In the first scenario most producers would reduce the use of inputs to a minimum and leave the raw cotton in the fields. In the second scenario the production of cotton would shift from conventional toward Integrated Production with a reduction of 30% with respect to the current hectarage.Cotton, Spain, Mid-Term Reform, Simulation, Multi-Criteria Decision Making, Agricultural and Food Policy, Crop Production/Industries,

Differences in citation impact across countries

Using a large dataset, indexed by Thomson Reuters, consisting of 4.4 million articles published in 1998-2003 with a five-year citation window for each year, this paper studies country citation distributions in a partition of the world into 36 countries and two geographical areas in the all-sciences case and eight broad scientific fields. The key findings are the following two. Firstly, the shape of country citation distributions is highly skewed and very similar to each other across all fields. Secondly, differences in country citation distributions appear to have a strong scale factor component. The implication is that, in spite of the skewness of citation distributions, international comparisons of citation impact in terms of country mean citations capture well such scale factors. The empirical scenario described in the paper helps understanding why, in each field and the all-sciences case, the country rankings according to (i) mean citations and (ii) the percentage of articles in each country belonging to the set formed by the 10% of the more highly cited papers are so similar to each other.Albarrán acknowledges additional financial support from the Spanish MEC through grants ECO2009-11165 and ECO2011-29751, and Ruiz-Castillo through grant SEJ2007-67436

Application of Geographic Infomration Systems (GIS) in the search for and characterization of raw materials of interest in ceramics and glass

En este trabajo se muestra la aplicación de un sistema de información geográfica (SIG) como herramienta eficaz a la hora de abordar varias fases de investigación sobre materias primas de interés para el sector de la Cerámica y el Vidrio, con dos ejemplos: prospección y caracterización de materias primas, utilizadas como material impermeabilizante además de potencial interés cerámico y estudio de canteras de extracción de caliza y mármol. Para ello, se han diferenciado tres fases en el trabajo: construcción de la base de datos cartográfica, fusión de las bases de datos y depuración; finalmente, se realiza el desarrollo de la aplicación. De este estudio se concluye que el SIG se convierte en una herramienta viva, a la que se le pueden ir incorporando nuevos datos, como son puntos de muestreo, resultados de ensayos y determinaciones realizadas con las muestras, nuevas vías y caminos, empresas que poseen la concesión, etc., como ha quedado expuesto con los ejemplos descritos. Todo ello permite una explotación mucho más racional y eficiente desde los puntos de vista técnico, medioambiental y económico. Se deduce un claro interés del método de trabajo propuesto con utilidad para investigadores, tecnólogos y empresarios del ámbito que se ocupan de la valorización de materias primas de aplicación en el procesamiento de materiales de este sector.This work shows the application of a geographic information system (GIS) as an effective tool to undertake several phases of research on raw materials of interest in ceramics and glass, with two examples: search for and characterization of raw materials to be used as impermeable materials in addition to their potential ceramic interest in terms of quarries and the quarrying of limestone and marble. For this, three phases of work have been differentiated: the construction of a cartographic database, the combining and distilling of the databases; and finally the development of the application. From this study, it was concluded that GIS becomes a living tool in which new data can be incorporated, such as sampling points, test results, determinations made with the samples, new approaches and directions, companies that have the concession, etc., as explained with the examples described. All of this enables more rational and efficient use of the materials from the technical, environmental, and economic standpoint. The working method proposed could be clearly useful for researchers, technicians, and businessmen of this sphere that are involved in evaluating raw materials to be applied in processing materials of this sector
