Psychometric Analysis of the Teaching Styles Survey in Physical Education (TSPE)

El objetivo principal fue analizar las propiedades psicométricas del cuestionario que valora los estilos de enseñanza con los que se identifican preferentemente los docentes de educación física. La muestra estuvo compuesta por 120 docentes de Educación Secundaria. Para el diseño del instrumento se partió del cuestionario DEMEVI al que 12 jueces expertos dieron la validación de contenido. Tras los respectivos análisis factoriales, exploratorios y confirmatorios, se obtuvo un modelo de cinco factores y de 20 ítems presentando índices de ajuste satisfactorios. Se obtuvieron niveles aceptables de consistencia interna y estabilidad temporal. El profesorado menor de 30 años valoraba más los estilos cognitivos, participativos y socializadores, mientras que en función del sexo, los hombres menores de 30 años se identificaban más con estilos de carácter tradicional frente a las mujeres de la misma edad que preferían los cognitivos. El cuestionario de estilos de enseñanza en educación física proporciona evidencias fiables y válidas para su usoThe objective of the study was to analyze the psychometric properties of the questionnaire which values teaching styles with which preferentially identify physical education teachers. The sample was composed of 120 secondary school teachers. In designing of the instrument they started from a DEMEVI questionnaire to which 12 experts judges got the validation of content. After the respective factor, exploratory and confirmatory analysis, five-factor model and 20 items were obtained, which showed satisfactory indexes of adjustment. Acceptable levels of internal consistency and temporal stability were obtained. Teachers under 30 years valued more the cognitive, participatory and socializing styles while men under 30 years of age identified more with traditional character styles compared to women of the same age who preferred the cognitive ones. The teaching styles questionnaire in physical education provides reliable and valid evidence for us

Análisis del perfil motivacional de diversos grupos de atletas y su repercusión en el nivel de satisfacción deportiva

The purpose of this study was to identify the motivation among different athletics groups and see the influence motivational profile of satisfaction feel them. The sample was composed of 51 subjects from schools and sport clubs in Murcia. The sample was classificated according to gender, age, frequency of practice, possession of federal license and type training. As instruments were used three test; BREQ-2 for self-determination, TEOSQ, for motivacional orientation and SSI, for satisfaction level. All them, adapted to the context athletic.The results showed more satisfaction level and less bore level in subjects with high task orientation and intrinsic motivation/self-determined, and greater motivation to achieve (ego and task). The ideal profile were younger women, federated, which train them frequently and always accompanied. The age was the most influential factor. These results could be studied by the coaches in order to they keep in mind the variables that can be modified such as training methodology to achieve greater satisfaction and of this form, a better adherence and competitive results. It would be wise to consider athletes from an early stage was facing the enjoyment of athletics for the future, not to reduce their level of satisfaction and motivation, increasing the possibility of sport dropout.El objetivo del presente estudio, es analizar la motivación que experimentan diversos grupos de atletas y como esta, influye en sunivel de satisfacción con el deporte. Se utilizó una muestra de 51 sujetos provenientes de escuelas y clubes de la Región de Murcia,siendo clasificada la muestra en función del género, edad, frecuencia de práctica, posesión de licencia federativa y tipo de entrenamiento. Como instrumentos se utilizaron el cuestionario BREQ-2 para la autodeterminación, TEOSQ, para la orientación motivacional y SSI para el nivel de satisfacción, todos ellos adaptados al contexto atlético. Los resultados mostraron mayor satisfacción y menor aburrimiento en los sujetos con alta orientación a la tarea y motivación intrínseca-autodeterminada, así como mayor motivación hacia el logro (ego y tarea). El perfil ideal fueron las mujeres más jóvenes, federadas, que realizan una práctica frecuente y siempre acompañadas, siendo la edad el factor más influyente. Estos resultados, podrían servir a los entrenadores para tener en cuenta qué variables pueden modificar tales como la metodología de entrenamiento, para lograr una mayor satisfacción y con ello, una mayor adherencia y resultados competitivos. Sería conveniente formar atletas desde las primeras etapas con orientación hacía el disfrute del atletismo para que de cara al futuro, no se reduzca su nivel de satisfacción y motivación y con ello, la posibilidad de abandono deportivo

Diseño y validación de un instrumento de observación de las conductas que alteran la convivencia en educación física

El objetivo del presente trabajo fue diseñar y validar un instrumento de observación de conductas que alteran la convivencia en las clases de Educación Física, que permita definirlas, categorizarlas y medirlas cuantitativamente. Este proceso de validación se llevó a cabo en varias fases y contó con la participación de seis jueces expertos en el ámbito de la enseñanza de la Educación Física y cuatro observadores formados en el análisis de las conductas que alteran el clima de convivencia en las clases de Educación Física. Observaron un total de diez clases de Educación Física, de sexto de Educación Primaria y de tercero de la Educación Secundaria de diez centros escolares diferentes, analizando la estructura del instrumento mediante procedimientos confirmatorios. El instrumento final estuvo formado por ocho conductas que alteran la convivencia en las clases de Educación Física, agrupadas en dos factores (conductas violentas y conductas de indisciplina y desinterés). Los resultados obtenidos en el proceso de validez, fiabilidad y consistencia interna indican que el instrumento diseñado es válido para registrar las conductas que alteran la convivencia en las clases de Educación Física y permite su aplicación sin la presencia del observador en el aula, minimizando así el efecto de esa presencia en el comportamiento del alumnado.The aim of this study was to design and validate an instrument of observation that would allow us to measure and quantify student misconduct during classes of physical education. This process of validation was carried out in several phases. Six expert judges in physical education teaching and four observers trained to measure student misconduct in physical education lessons participated in the process, analysing ten physical education lessons of sixth and ninth grade from ten different schools, settings the structure of the instrument through confirmatory procedures. The final instrument consisted of eight items describing different kinds of student misconduct during physical education classes, grouped into two categories (violent behaviours and undisciplined and disinterested behaviours). The results obtained in the process of validation, reliability and internal consistency suggest that the instrument designed is optimally useful and reliable to measure student misconduct during physical education classes, allowing its application without the presence of the investigator in the classroom, thus minimizing its effect on the behaviour of the student body

DNA multigene characterization of Fasciola hepatica and Lymnaea neotropica and its fascioliasis transmission capacity in Uruguay, with historical correlation, human report review and infection risk analysis

Fascioliasis is a highly pathogenic zoonotic disease emerging in recent decades, in part due to the effects of climate and global changes. South America is the continent presenting more numerous human fascioliasis endemic areas and the highest Fasciola hepatica infection prevalences and intensities known in humans. These serious public health scenarios appear mainly linked to altitude areas in Andean countries, whereas lowland areas of non-Andean countries, such as Uruguay, only show sporadic human cases or outbreaks. To understand this difference, we characterized F. hepatica from cattle and horses and lymnaeids of Uruguay by sequencing of ribosomal DNA ITS-2 and ITS-1 spacers and mitochondrial DNA cox1, nad1 and 16S genes. Results indicate that vectors belong to Lymnaea neotropica instead of to Lymnaea viator, as always reported from Uruguay. Our correlation of fasciolid and lymnaeid haplotypes with historical data on the introduction and spread of livestock species into Uruguay allow to understand the molecular diversity detected. We study the life cycle and transmission features of F. hepatica by L. neotropica of Uruguay under standardized experimental conditions to enable a comparison with the transmission capacity of F. hepatica by Galba truncatula at very high altitude in Bolivia. Results demonstrate that although L. neotropica is a highly efficient vector in the lowlands, its transmission capacity is markedly lower than that of G. truncatula in the highlands. On this baseline, we review the human fascioliasis cases reported in Uruguay and analyze the present and future risk of human infection in front of future climate change estimations

Modelo cognitivo-motivacional para la promoción de la persistencia en Educación Superior: relación entre la organización docente, la competencia del alumnado y el «grit»

The teaching process and the success of learning are closely linked to cognitive and motivational factors. The purpose of this study was to test a multilevel model in higher education students on the relationship between the teaching organization and the dimensions of grit and perceived competence. Participated 3033 students, who answered utility dimension inventories and organization, competition and grit. The results show that at the individual level, the organization by the teaching staff focused on the utility and organization is positively related to the student's scream, this relationship being mediated by the perceived competence. The organizational improvement of the teacher generates student achievements through the positive impact on their competence.«El proceso de enseñanza y el éxito del aprendizaje están estrechamente vinculados a factores cognitivos y motivacionales. Este estudio tuvo como propósito poner a prueba un modelo multinivel en estudiantes de Educación Superior sobre la relación de la organización docente y las dimensiones del grit, mediada por la competencia percibida. Participaron 3.033 estudiantes de cinco países, a los que se les midió la utilidad y organización del docente, la competencia y el grit. Los resultados muestran que, a nivel individual, la organización por parte del profesorado centrada en la utilidad se relacionó positivamente con el grit del estudiante cuando estaba mediada por la competencia percibida. Se sugiere que el profesor mejore su tarea organizativa docente, pues genera mayores logros en el estudiante a través del impacto positivo sobre su competencia

Short-Term Environmental Enrichment Rescues Adult Neurogenesis and Memory Deficits in APPSw,Ind Transgenic Mice

Epidemiological studies indicate that intellectual activity prevents or delays the onset of Alzheimer's disease (AD). Similarly, cognitive stimulation using environmental enrichment (EE), which increases adult neurogenesis and functional integration of newborn neurons into neural circuits of the hippocampus, protects against memory decline in transgenic mouse models of AD, but the mechanisms involved are poorly understood. To study the therapeutic benefits of cognitive stimulation in AD we examined the effects of EE in hippocampal neurogenesis and memory in a transgenic mouse model of AD expressing the human mutant β-amyloid (Aβ) precursor protein (APPSw,Ind). By using molecular markers of new generated neurons (bromodeoxiuridine, NeuN and doublecortin), we found reduced neurogenesis and decreased dendritic length and projections of doublecortin-expressing cells of the dentate gyrus in young APPSw,Ind transgenic mice. Moreover, we detected a lower number of mature neurons (NeuN positive) in the granular cell layer and a reduced volume of the dentate gyrus that could be due to a sustained decrease in the incorporation of new generated neurons. We found that short-term EE for 7 weeks efficiently ameliorates early hippocampal-dependent spatial learning and memory deficits in APPSw,Ind transgenic mice. The cognitive benefits of enrichment in APPSw,Ind transgenic mice were associated with increased number, dendritic length and projections to the CA3 region of the most mature adult newborn neurons. By contrast, Aβ levels and the total number of neurons in the dentate gyrus were unchanged by EE in APPSw,Ind mice. These results suggest that promoting the survival and maturation of adult generated newborn neurons in the hippocampus may contribute to cognitive benefits in AD mouse models

Sports graduate capabilities and competencies: a comparison of graduate and employer perceptions in six EU countries

The graduate employment market faces ever-increasing socio-economic and political pressures. Higher Education Institutions and the sport sector in the EU have an important role in contributing to graduate employment. The aims of the study were: (1) to assess general perceptions of employability, and (2) to assess sports graduates’ and employers’ perceptions of specific capabilities and competencies in order to identify possible improvements for sports graduate employability programmes. A cross-sectional survey of sports graduates and employers was administered in six EU countries including the UK, France, Germany, Spain, Greece and the Czech Republic to assess graduate and employer perceptions. A graduate capabilities and competencies framework was devised to assess personal, interpersonal, cognitive, role-specific and generic skills. Responses were elicited from 1132 sports graduates and 327 employers. There was generally a wide difference of opinion between employers and sports graduates in terms of the importance and possession of a number of capabilities and competencies. There is a need for the Higher Education sector and employers to take responsibility in ensuring that work experience, work placement and volunteering opportunities are embedded in curricula and to ensure the fitness of purpose of what and how graduate capabilities and competencies are assessed

Why Are Outcomes Different for Registry Patients Enrolled Prospectively and Retrospectively? Insights from the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF).

Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

Improved risk stratification of patients with atrial fibrillation: an integrated GARFIELD-AF tool for the prediction of mortality, stroke and bleed in patients with and without anticoagulation.

OBJECTIVES: To provide an accurate, web-based tool for stratifying patients with atrial fibrillation to facilitate decisions on the potential benefits/risks of anticoagulation, based on mortality, stroke and bleeding risks. DESIGN: The new tool was developed, using stepwise regression, for all and then applied to lower risk patients. C-statistics were compared with CHA2DS2-VASc using 30-fold cross-validation to control for overfitting. External validation was undertaken in an independent dataset, Outcome Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF). PARTICIPANTS: Data from 39 898 patients enrolled in the prospective GARFIELD-AF registry provided the basis for deriving and validating an integrated risk tool to predict stroke risk, mortality and bleeding risk. RESULTS: The discriminatory value of the GARFIELD-AF risk model was superior to CHA2DS2-VASc for patients with or without anticoagulation. C-statistics (95% CI) for all-cause mortality, ischaemic stroke/systemic embolism and haemorrhagic stroke/major bleeding (treated patients) were: 0.77 (0.76 to 0.78), 0.69 (0.67 to 0.71) and 0.66 (0.62 to 0.69), respectively, for the GARFIELD-AF risk models, and 0.66 (0.64-0.67), 0.64 (0.61-0.66) and 0.64 (0.61-0.68), respectively, for CHA2DS2-VASc (or HAS-BLED for bleeding). In very low to low risk patients (CHA2DS2-VASc 0 or 1 (men) and 1 or 2 (women)), the CHA2DS2-VASc and HAS-BLED (for bleeding) scores offered weak discriminatory value for mortality, stroke/systemic embolism and major bleeding. C-statistics for the GARFIELD-AF risk tool were 0.69 (0.64 to 0.75), 0.65 (0.56 to 0.73) and 0.60 (0.47 to 0.73) for each end point, respectively, versus 0.50 (0.45 to 0.55), 0.59 (0.50 to 0.67) and 0.55 (0.53 to 0.56) for CHA2DS2-VASc (or HAS-BLED for bleeding). Upon validation in the ORBIT-AF population, C-statistics showed that the GARFIELD-AF risk tool was effective for predicting 1-year all-cause mortality using the full and simplified model for all-cause mortality: C-statistics 0.75 (0.73 to 0.77) and 0.75 (0.73 to 0.77), respectively, and for predicting for any stroke or systemic embolism over 1 year, C-statistics 0.68 (0.62 to 0.74). CONCLUSIONS: Performance of the GARFIELD-AF risk tool was superior to CHA2DS2-VASc in predicting stroke and mortality and superior to HAS-BLED for bleeding, overall and in lower risk patients. The GARFIELD-AF tool has the potential for incorporation in routine electronic systems, and for the first time, permits simultaneous evaluation of ischaemic stroke, mortality and bleeding risks.

Two-year outcomes of patients with newly diagnosed atrial fibrillation: results from GARFIELD-AF.

AIMS: The relationship between outcomes and time after diagnosis for patients with non-valvular atrial fibrillation (NVAF) is poorly defined, especially beyond the first year. METHODS AND RESULTS: GARFIELD-AF is an ongoing, global observational study of adults with newly diagnosed NVAF. Two-year outcomes of 17 162 patients prospectively enrolled in GARFIELD-AF were analysed in light of baseline characteristics, risk profiles for stroke/systemic embolism (SE), and antithrombotic therapy. The mean (standard deviation) age was 69.8 (11.4) years, 43.8% were women, and the mean CHA2DS2-VASc score was 3.3 (1.6); 60.8% of patients were prescribed anticoagulant therapy with/without antiplatelet (AP) therapy, 27.4% AP monotherapy, and 11.8% no antithrombotic therapy. At 2-year follow-up, all-cause mortality, stroke/SE, and major bleeding had occurred at a rate (95% confidence interval) of 3.83 (3.62; 4.05), 1.25 (1.13; 1.38), and 0.70 (0.62; 0.81) per 100 person-years, respectively. Rates for all three major events were highest during the first 4 months. Congestive heart failure, acute coronary syndromes, sudden/unwitnessed death, malignancy, respiratory failure, and infection/sepsis accounted for 65% of all known causes of death and strokes for <10%. Anticoagulant treatment was associated with a 35% lower risk of death. CONCLUSION: The most frequent of the three major outcome measures was death, whose most common causes are not known to be significantly influenced by anticoagulation. This suggests that a more comprehensive approach to the management of NVAF may be needed to improve outcome. This could include, in addition to anticoagulation, interventions targeting modifiable, cause-specific risk factors for death. CLINICAL TRIAL REGISTRATION: http://www.clinicaltrials.gov.
