Design and validation of a questionnaire about the perceptions of dual career student-athletes (ESTPORT)

Abstract The purpose of this paper was to design and validate a questionnaire about the perceptions of elite studentathletes at university relating to their dual career. In the initial creation of the instrument, constructs were defined and three dimensions were established: academic life, sporting life and sports tutor. After a process of ‘back translation’, experts (n = 8) agreed the construct to ensure content validity, the dimensions and the questionnaire questions. Statistical analysis of the items showed adequate comprehension to confirm content validity of participants (n = 30). In construct validity (n = 73), the results showed correct psychometric quality, internal consistency, reliability and adequacy of the structural model. The instrument had evidence of external validity, since the results were congruent with the main findings of the research. This questionnaire was found to be a valid and reliable assessment instrument, consisting of 84 questions (in Spanish and English language), that enables the perception of elite student-athletes to be known about their dual career whilst at university

Diseño y validación del cuestionario de percepción de los estudiantes universitarios-deportistas de alto nivel sobre la carrera dual (ESTPORT).

El objetivo de la presente investigación fue diseñar y validar un instrumento de evaluación para conocer la percepción de los estudiantes universitarios-deportistas de alto nivel sobre la carrera dual. En la creación inicial del instrumento se definió el constructo y se establecieron tres dimensiones: carrera académica, carrera deportiva y tutor deportivo. En la validez de contenido, tras un proceso de traducción inversa, los expertos (n = 8) valoraron positivamente el constructo, las dimensiones y las preguntas cuestionario. Los resultados estadísticos de los ítems mostraron la adecuada validez de comprensión de los participantes (n = 30). En la validez de constructo (n = 73), las propiedades psicométricas mostraron la adecuada calidad psicométrica, consistencia interna, fiabilidad y bondad de ajuste. El instrumento también contó con evidencias externas de validez, dado que los resultados fueron en la línea de lo que demuestra la literatura. Por ello, este trabajo ofrece un cuestionario válido y fiable de 84 preguntas (en español y en inglés) que permite medir la percepción de los estudiantes universitarios-deportistas de alto nivel sobre la carrera dual.Actividad Física y Deport

Implementing the European Sports Leadership Programme: A vehicle to help development graduate workplace competencies

This research was part of a large intervention study implementing the European Sports Leadership Programme (ESLP). This paper reports the outcomes of the qualitative study that employed focus groups to assess the students’ perceptions of the 15 competencies determined according to the Framework for qualifications of the European Higher Education Area, before and after the ESLP. Focus groups were carried out at each of the five universities. The ESLP involved university students working as a sports leader for 24 months with the aim to engage more students in university sport, whilst they took part in a graduate employability programme. Each university recruited five sports leaders in their second year at university, to deliver 10 new sport and recreational activities targeting the wider inactive or semi-active student population. Findings highlighted that Organization and planning, Oral and written communication, Development of planning and decision making, and Teamworking, followed closely by Emotional control and Adapting to new situations, were the most commonly reported competencies. They affirmed that this programme had helped to develop these competencies. Use of information, communication and technology, Communication in a foreign language, Research and Emotional control were the most common competencies that students stated they needed to improve further. This research found that implementing the ESLP helped to develop students’ perceptions of their workplace and career competencies. The ESLP is therefore, recommended as one approach to helping universities to develop student’s workplace and career competencies

Effects of a sport leadership programme on the perceptions of university students about their leadership competencies (Efectos de un programa de liderazgo deportivo sobre las percepciones de alumnado universitario)

The main purpose of this study was to evaluate the effects of a sport leadership programme (ESLP) on variables related to the leaders’ perception regarding instrumental, personal, and systemic skills in university students. In doing so, the second purpose was to analyse the trans-cultural validity of the Cuestionario de Evaluación de Competencias Transversales de Grado (CECTGRA). Participated 61 students as leaders, 25 mentors and 25 employers, from five European countries. The design was pre-test-post-test, following a longitudinal approach of 24 months to evaluate the effects of the ESLP on variables related to the leader’s perception. An adaptation of the CECTGRA was administered. The questionnaire was valid and reliable to know the effects of the ESLP on the students’ perceptions. However, the sports leaders did not improve their perceptions of competence regarding development, mastery and relevance after the application of the programme. From the finding of this study it is recommended to improve the programme based on the leadership competencies to develop, the teaching-learning methodologies to follow, the activities to implement, and the roles to determine

Declarative Experimentation in Information Retrieval Using PyTerrier

The advent of deep machine learning platforms such as Tensorflow and Pytorch, developed in expressive high-level languages such as Python, have allowed more expressive representations of deep neural network architectures. We argue that such a powerful formalism is missing in information retrieval (IR), and propose a framework called PyTerrier that allows advanced retrieval pipelines to be expressed, and evaluated, in a declarative manner close to their conceptual design. Like the aforementioned frameworks that compile deep learning experiments into primitive GPU operations, our framework targets IR platforms as backends in order to execute and evaluate retrieval pipelines. Further, we can automatically optimise the retrieval pipelines to increase their efficiency to suite a particular IR platform backend. Our experiments, conducted on TREC Robust and ClueWeb09 test collections, demonstrate the efficiency benefits of these optimisations for retrieval pipelines involving both the Anserini and Terrier IR platforms

The chemical evolution of Omega Centauri's progenitor system

Chemical evolution models are presented for the anomalous globular cluster Omega Centauri. After demonstrating that the chemical features of Omega Cen can not be reproduced in the framework of the closed-box self-enrichment scenario, we discuss a model in which this cluster is the remnant of a dwarf spheroidal galaxy evolved in isolation and then swallowed by the Milky Way. Both infall of primordial matter and metal-enriched gas outflows have to be considered in order to reproduce the stellar metallicity distribution function, the age-metallicity relation and several abundance ratios. Yet, as long as an ordinary stellar mass function and standard stellar yields are assumed, we fail by far to get the enormous helium enhancement required to explain the blue main sequence (and, perhaps, the extreme horizontal branch) stellar data. Rotating models of massive stars producing stellar winds with large helium excesses at low metallicities have been put forward as promising candidates to solve the `helium enigma' of Omega Cen (Maeder & Meynet, 2006, A&A, 448, L37). However, we show that for any reasonable choice of the initial mass function the helium-to-metal enrichment of the integrated stellar population is unavoidably much lower than 70 and conclude that the issue of the helium enhancement in Omega Cen still waits for a satisfactory explanation. We briefly speculate upon possible solutions.Comment: 11 pages, 9 figures; accepted for publication in MNRA
