Intuitive eating: A novel eating style? Evidence from a Spanish sample
2020
Contains fulltext : 217000.pdf (Publisher’s version ) (Closed access) Intuitive eating is defined as an adaptive way of eating that maintains a strong connection with the internal physiological signs of hunger and satiety. It has four elements: unconditional permission to eat whenever and whatever food is desired, eating for physical rather than for emotional reasons, reliance on hunger and satiety cues to determine when and how much to eat, and body-food choice congruence. In this study, we assessed the differences and similarities between intuitive eating, as measured with the Intuitive Eating Scale-2, and eating styles (restrained, emotional, and external eating), as assessed with the Du…
PO-CALC: A novel tool to correct common inconsistencies in the measurement of phenoloxidase activity
2015
Abstract A broad range of physiological and evolutionarily studies requires standard and robust methods to assess the strength and activity of an individual’s immune defense. In insects, this goal is generally reached by spectrophotometrically measuring (pro-) phenoloxidase activity, an enzymatic and non-specific process activated after wounding and parasite infections. However, the literature surprisingly lacks a standard method to calculate these values from spectrophotometer data and thus to be able to compare results across studies. In this study, we demonstrated that nine methods commonly used to extract phenoloxidase activities (1) provide inconsistent results when tested on the same …
Tourism-led growth hypothesis in the top ten tourist destinations: New evidence using the quantile-on-quantile approach
2017
This paper examines the empirical validity of the tourism-led growth hypothesis in the top ten tourist destinations in the world (China, France, Germany, Italy, Mexico, Russia, Spain, Turkey, the United Kingdom, and the United States) using the quantile-on-quantile (QQ) approach and a new index of tourism activity that combines the most commonly used tourism indicators. This methodology, recently introduced by Sim and Zhou (2015), provides an ideal framework with which to capture the overall dependence structure between tourism development and economic growth. The empirical results primarily show a positive relation between tourism and economic growth for the ten countries considered with s…
Development of the Parents' Perception of their Involvement in their Child's Tennis Activity Questionnaire (Q-PPICTA)
2013
The purpose of this study was to develop and validate a questionnaire for assessing parents' perception of their involvement in their children's tennis activity (Q-PPICTA). The validation required four successive studies. In study 1, a preliminary version of the questionnaire was formulated after selecting and adapting items taken from existing questionnaires and interviews conducted with the parents of 36 young tennis players. Three factors for measuring parental involvement in sport were identified and retained: emotional, logistic, and informational supports. In study 2, exploratory factor analyses were performed on data collected from 214 parents of tennis players. Results attested the …
Individuals and Collectivity between the Principle of noncontradiction and joint commitment
2017
In this paper I pay attention to and reflect upon the role and the nature of the human being considered as an individual that acts in a collective dimension and thus contributes to build a social reality. What is required to talk of collectivity? Is it anything that goes beyond the interacting individuals or not? In order to talk of collectivity, do we need to talk of a plural subject as well as of collective beliefs, (as Margaret Gilbert does), or not? These are some questions that are addressed in my paper. In particular, I outline the view that the collectivity is the relationship among interacting individuals in the exercise of their own rationality. Consequently, I argue that the colle…
¿Implicar a los estudiantes en la modificación de rúbricas influye sobre su percepción de validez?
2019
[EN] Oral presentation is one of the fundamental competences in the teaching-learning process for most of the university students and rubrics could be used as a useful tool in this process. Therefore, the main objective was to determine the perception of validity and utility of a rubric for students of the Physical Education and Sports Sciences degree, considering also if they were involved or not in the rubric’s development. 115 students participated, in two groups. The teacher of the subject gave to both groups the same rubric to evaluate their oral presentations. So, one of the groups modified and prepared the rubric´s elements. After oral presentations, both groups completed a rubric's …
Relación entre la percepción de validez de una rúbrica, el rendimiento académico y la autorregulación de estudiantes de ciencias del deporte
2021
[EN] The use of rubrics can be an especially useful tool to align the teaching, learning and evaluation processes of oral presentation. Its validity is essential to assess academic performance and may be influenced by student self-regulation. The objective of the study was to determine the perception of validity and utility of a rubric for students of the Physical Education and Sports Sciences degree, as well as to identify the relationship between this perception, their academic performance and their self-regulation. 123 students participated in the study. The teacher of the subject provided the rubric to evaluate oral presentations. After oral presentations, students answered two question…
Ensuring content validity of psychological and educational tests – the role of experts
2020
Many test developers try to ensure the content validity of their tests by having external experts review the items in terms of relevance, difficulty, clarity, and so on. Although this approach is widely accepted, a closer look reveals there are several pitfalls that need to be avoided if experts’ advice is to be truly helpful. First, I offer a classification of tasks experts are given by test developers as reported on in the literature dealing with procedures of drawing on experts’ advice. Second, I review a sample of reports on test development (N = 72) to identify the common current procedures for selecting and consulting experts. Results indicate that often the choice of experts seems to…

A Critical Review Of The Hardiness Scales
2018
INTRODUCTION: The construct of hardiness - structured in the control, commitment and challenge components - is a personality variable that allows individuals to respond effectively to stress demands, to perform better and to stay healthier. Individuals with high scores on these three factors show less powerlessness and alienation, interpret life events as controllable, interesting and as growth opportunities. Although in the last forty years many scholars had contributed to consolidate the hardiness theoretical framework, a substantial critical issue emerges with regard to the large heterogeneity of the scales used to measure hardiness. OBJECTIVE: The main aim of the study is to conduct a c…
