'REOFUT' as an Observation Tool for Tactical Analysis on Offensive Performance in Soccer: Mixed Method Perspective

2019

Performance analysis in complex sports like soccer requires the study of the influence of the interaction between both teams during the game on final performance. The mixed methods approach involves the collection, analysis, and interpretation of qualitative and quantitative data for the same purpose and within the framework of the same study. To build certain observation tools, mixed methods are necessary in order to take advantage of integration between qualitative and quantitative elements. The aim of this study was to develop a new no standard observation tool to analyze soccer offensive performance considering not only the observed team but also some aspects of the opponent behavior, a…

Factorial Validity of the "Spanish Burnout Inventory" (SBI) in a Sample of Mexican Doctors

2010

El objetivo del estudio fue evaluar la validez factorial del Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo (CESQT). Se hipotetizó un modelo de cuatro factores. La muestra estuvo compuesta por 110 médicos del Instituto Mexicano del Seguro Social. El instrumento está formado por 20 ítems distribuidos en 4 subescalas: Ilusión por el trabajo (5 ítems), Desgaste psíquico (4 ítems), Indolencia (6 ítems), y Culpa (5 ítems). El modelo presentó un ajuste adecuado: GFI = .83, RMSEA = .061, NNFI = .90, CFI = .92, PNFI = .65. Los resultados indican que el CESQT presentó en esta muestra validez factorial y valores de consistencia interna adecuados. The purpose of this study was…

Transcranial Alternating Current Stimulation (tACS) Does Not Affect Sports People’s Explosive Power: A Pilot Study

2021

Purpose: This study is aimed to preliminary investigate whether transcranial alternating current stimulation (tACS) could affect explosive power considering genetic background in sport subjects.Methods: Seventeen healthy sports volunteers with at least 3 years of sports activities participated in the experiment. After 2 weeks of familiarization performed without any stimulation, each participant received either 50 Hz-tACS or sham-tACS. Before and after stimulation, subjects performed the following tests: (1) the squat jump with the hands on the hips (SJ); (2) countermovement jump with the hands on the hips (CMJ); (3) countermovement jump with arm swing (CMJ-AS); (4) 15-s Bosco’s test; (5) s…

A new approach for estimating a nonlinear growth component in multilevel modeling

2011

This study presents a new approach to estimation of a nonlinear growth curve component with fixed and random effects in multilevel modeling. This approach can be used to estimate change in longitudinal data, such as day-of-the-week fluctuation. The motivation of the new approach is to avoid spurious estimates in a random coefficient regression model due to the synchronized periodical effect (e.g., day-of-the-week fluctuation) appearing both in independent and dependent variables. First, the new approach is introduced. Second, a Monte Carlo simulation study is carried out to examine the functioning of the proposed new approach in the case of small sample sizes. Third, the use of the approac…

Depressive symptoms during adolescence: Do learning difficulties matter?

2011

To examine whether learning difficulties play a role in depressive symptoms, 658 Finnish adolescents were asked to complete scales for depression three times during the transition to post-comprehensive education. They also reported on their learning difficulties and feelings of inadequacy as a student. The results showed that learning difficulties prospectively predicted depressive symptoms. Moreover, the impact of learning difficulties was mediated via inadequacy as a student: learning difficulties predicted feelings of inadequacy as a student which, in turn, contributed to greater increases in depressive symptoms. Finally, gender moderated the association between learning difficulties an…

Accuracy, Coherence, and Discrepancy in Self and Other Reports: Moving Toward an Interactive Perspective of Organizational Dissent.

2013

The purpose of this study was twofold and involved examining the viability of using the Organizational Dissent Scale as an other-report instrument, and developing additional perceptual data related to dissent expression. A sample of 291 people completed survey questionnaire measures of organizational dissent. Equal-sized groups ( n = 97) completed either a self-report, a workplace colleague other-report, or an organizational outsider other-report. Results indicated the Organizational Dissent Scale performed reliably as an other-report, but it showed some tendency for social desirability. In addition, findings suggested that certain indicators of proximity to the dissenter reduced discrepan…

T9+HUD: Physical Keypad and HUD can Improve Driving Performance while Typing and Driving

2016

We introduce T9+HUD, a text entry method designed to decrease visual distraction while driving and typing. T9+HUD combines a physical 3x4 keypad on the steering wheel with a head-up-display (HUD) for projecting output on the windshield. Previous work suggests this may be a visually less demanding way to type while driving than the popular case which requires shifts of visual attention away from the road. We present a prototype design and report first results from a controlled evaluation in a driving simulator. While driving, the T9+HUD text entry rate was equal compared to a dashboard-mounted touchscreen device, but it reduced lane deviations by 70%. Furthermore, there was no significant di…

Citizens' Communication Habits and Use of ICTs During Crises and Emergencies

2014

In this article, citizens’ communication habits and use of information and communication technologies during crises and emergencies are discussed from the perspective of community resilience. The topic is approached qualitatively by exploring citizens’ perceptions, and the data were gathered by means of focus groups in storm-prone and flood-prone areas in Finland. The results indicate that citizens consider emergency communication to be mostly unidirectional: from authorities to the public. However, because crises are often complex and fast developing, cooperation among response organizations and citizen groups is needed to coproduce safety and in adapting to changing situations. Organizati…
