Direct Instruction vs. Cooperative Learning in Physical Education: Effects on Student Learning, Behaviors, and Subjective Experience
2020
(1) Background: The objective was to analyze if cooperative learning (CL) can have benefits compared to direct instruction (DI) in learning, behavior, and subjective experience of pupils. (2) Methods: An intervention was performed with a counterbalanced within-subjects design. To perform the intervention, 75 schoolchildren aged 10 to 12 from four primary classes were divided into two groups, and two units were taught in each one, namely &ldquo
Emotional intelligence intervention in older adults to improve adaptation and reduce negative mood.
2020
AbstractObjectives:Emotional intelligence (EI) is a strong predictor of negative mood. Applying emotional skills correctly can help to increase positive emotional states and reduce negative ones. This study aims to implement EI intervention designed to improve clarity, repair EI dimensions and coping strategies, and reduce negative mood in older adults.Design:Participants were randomly assigned to the treatment or control group.Setting:Participants were evaluated individually before and after the intervention.Participants:Participants included 111 healthy older adults; 51 in the treatment group and 60 in the control group.Intervention:An EI program was implemented. The program was administe…
The Effects of Mindfulness and Self-Compassion on Improving the Capacity to Adapt to Stress Situations in Elderly People Living in the Community
2015
ABSTRACTObjectives: This study aimed to show the effectiveness of mindfulness and self-compassion therapy in improving coping ability and adaptation to stressful situations in the elderly.Methods: Forty-five elderly non-institutionalized adults were randomized to either treatment or a treatment waiting list. A pre- and post-treatment assessment was performed, consisting of the Brief Resilient Coping Scale (BRCS), Depression Anxiety Stress Scales (DASS), and Coping Strategies Questionnaire. The program was developed over 10 sessions lasting 120 minutes each.Results: Analysis of variance for repeated measures showed significant differences in the time-group interaction for the treatment’s eff…
Individual, co-active and collective coping and organizational stress: A longitudinal study
2019
This study aims to identify the association between changes in three types of problem-focused coping (individual, organizational co-active and collective) and the change in the appraisal of different facets of employees' stress and the organizational stress climate. These relationships are tested by means of Bayesian Multilevel Structural Equation Modeling and a two-wave panel design. The sample is composed of 525 teachers in 100 schools. Stress experiences and coping behaviors are assessed during the first and third terms of the academic year. The results show that an increase in the use of individual problem-focused coping has little to no effect on the decrease in individual stress appra…
A Reciprocal Effects Model of the Temporal Ordering of Coping and Defenses
2016
This study aimed to examine how coping and defenses are related over time, using a two-wave cross-lagged panel design. Coping and defenses were assessed before and after a sport competition in a sample of 296 competitive athletes. Partial least squares path modeling results showed that (a) pre-competitive mature defenses predicted increases in the use of task-oriented coping during competition; (b) pre-competitive immature defenses predicted an increase in the use of disengagement-oriented coping during competition; and (c) pre-competitive task-oriented coping predicted an increase in the use of immature defenses during competition. Overall, our findings suggest that defenses predict the us…
Emotional user experience: Traits, events, and states☆
2015
Emotional experience has become an important topic in human-technology interaction research and design. Nevertheless, such research and design often lacks a proper explanatory basis and methodologically robust operationalisation. In this article, a conceptualisation of emotional user experience is formulated based on the appraisal theory of emotion, where the goal congruence of the interaction events and the task-independent individual traits are thought to underlie the user's emotional response. A laboratory study with N=50 participants conducting ordinary computer tasks is reported. The results suggest that subjective emotional experience depends on a number of factors relating to individ…
Smart camera based on an Embedded HW/SW Co-Processor
2008
Abstract This paper describes an image acquisition and a processing system based on a new coprocessor architecture designed for CMOS sensor imaging. The system exploits the full potential CMOS selective access imaging technology because the coprocessor unit is integrated into the image acquisition loop. The acquisition and coprocessing architecture are compatible with the majority of CMOS sensors. It enables the dynamic selection of a wide variety of acquisition modes as well as the reconfiguration and implementation of high-performance image preprocessing algorithms (calibration, filtering, denoising, binarization, pattern recognition). Furthermore, the processing and data transfer, from t…
Supercontinuum generation with 532 nm quasi-continuum pulses in photonic crystal fibre tapers
2007
We report experimental results on supercontinuum generation in PCF tapers using quasi-continuous pump pulses of 7 ns duration at 532 nm. SC generation in normal and anomalous dispersion regimes are presented. Introduction Supercontinuum generation (SC) in photonic crystal fibres (PCF), fibre tapers, and PCF tapers has been demonstrated in the past with pump pulses of fs, ps, and tenths of ns duration [1-2]. Here, we present experimental results on SC generation in PCF tapers using quasi-continuous pump pulses of 7 ns duration at 532 nm. Fabrication of the PCF tapers The PCF from which the tapers were made, was a large-air-hole PCF ("cobweb" PCF) with two rings of air holes around a solid si…
Rationale, design and methods of CTCA-PRORECAD (Computed Tomography Coronary Angiography Prognostic Registry for Coronary Artery Disease): a multicen…
2013
PURPOSE: This study was done to assess the prognostic value of computed tomography coronary angiography (CTCA) in a large multicentre population of patients with suspected coronary artery disease (CAD) and, in particular, its incremental value compared with traditional methods for risk stratification. MATERIALS AND METHODS: This is a retrospective observational study that began in January 2003 conducted on patients with suspected CAD assessed with CTCA on the basis of symptoms (chest pain, dyspnoea) and/or abnormal or equivocal stress test and/or a high cardiovascular risk profile. The participating centres will provide data obtained with CTCA performed with 16-slice or higher equipment. Ex…
Bioactive pyrrole-based compounds with target selectivity
2020
The discovery of novel synthetic compounds with drug-like properties is an ongoing challenge in medicinal chemistry. Natural products have inspired the synthesis of compounds for pharmaceutical application, most of which are based on N-heterocyclic motifs. Among these, the pyrrole ring is one of the most explored heterocycles in drug discovery programs for several therapeutic areas, confirmed by the high number of pyrrole-based drugs reaching the market. In the present review, we focused on pyrrole and its hetero-fused derivatives with anticancer, antimicrobial, and antiviral activities, reported in the literature between 2015 and 2019, for which a specific target was identified, being resp…
