Validity of three smartwatches in estimating energy expenditure during outdoor walking and running.
2022
Commercially wrist-worn devices often present inaccurate estimations of energy expenditure (EE), with large between-device differences. We aimed to assess the validity of the Apple Watch Series 6 (AW), Garmin FENIX 6 (GF) and Huawei Watch GT 2e (HW) in estimating EE during outdoor walking and running. Twenty young normal-weight Chinese adults concurrently wore three index devices randomly positioned at both wrists during walking at 6 km/h and running at 10 km/h for 2 km on a 400- meter track. As a criterion, EE was assessed by indirect calorimetry (COSMED K5). For walking, EE from AW and GF was significantly higher than that obtained by the K5 (p < 0.001 and 0.002, respectively), but…
Technical determinants of competitive rifle shooting performance
2018
The purpose of this thesis was to identify technical determinants of elite level air rifle and biathlon standing shooting performance and investigate how these technical determinants are affected by training, competition situation, or intense exercise. Forty international and national level air rifle shooters and 17 biathletes participated in the studies. In air rifle shooting, shooting performance, aiming point trajectory, and postural balance were measured from each shot in a simulated competition series in the training situation and in the actual competition situation. The shooters’ competition results were collected from each measured season. In biathlon, the same shooting technical var…
Literacy instruction in first grade: classroom‐level associations between reading skills and literacy instruction activities
2022
Background Adapting instruction to individual students' needs is known to be effective, but there is a lack of evidence whether students' reading skills are associated with literacy instruction activities at classroom-level. Both the content of the literacy instruction and teachers' instructional support through instructional management are considered. Methods The data were collected in the context of Finland where first graders' reading skills show great variation at school entry but rapid progress. Students (n = 616) were individually tested on their reading skills, and literacy lessons in 35 classrooms were video recorded in the autumn of first grade. Multilevel path analyses were conduc…
Estudio farmacogenético del tratamiento del cáncer de mama basado en antraciclinas y taxanos
2016
Existe una importante variabilidad interindividual en la respuesta a los medicamentos que condiciona que no sea fácil predecir la efectividad o seguridad de un fármaco en un paciente concreto. La Farmacogenética (PGt) estudia el vínculo entre las variaciones en la secuencia de ADN de un paciente y su respuesta al tratamiento farmacológico. La variación de un único nucleótido puede tener consecuencias dramáticas, de modo que la identificación de variantes que alteren la función o expresión de las proteínas implicadas en la farmacocinética o farmacodinamia y su efecto final sobre la respuesta es el objetivo de la PGt. El Cáncer de Mama (CM) es el tipo de cáncer más frecuente en mujeres. A pes…
Socialization Into Teaching Physical Education – Acculturative Formation of Perceived Strengths
2015
1. IntroductionIt is common that physical education (PE) in primary schools is taught by generalist class teachers. They have been found to possess strong socially constructed beliefs about teaching and their teaching competencies already before they enter formal teacher preparation. These beliefs act as filters when acquiring and interpreting new information thus influencing what is learned during the formal teacher preparation (Capel & Katene, 2000; Curtner-Smith, 2001; Doolittle, Dodds, & Placek, 1993; Hutchinson, 1993; Lawson, 1983; Lortie, 1975; Matanin & Collier, 2003; Pajares, 1992; Placek, Dodds, Doolittle, Portman, Ratliffe & Pinkham, 1995; Randall & Maeda, 2010; Richardson, 2003).…
Contents and functions of dramatizations in team decision making
2017
This study examines the contents and functions of dramatizations in natural team decision making. Theoretically, the study employs symbolic convergence theory to understand decision making as a complex phenomenon constructed in symbolic communication. Observational meeting data and thematic interview data from an autonomous team in Finland were analyzed. A fantasy theme analysis and an inductive, rhetorical discourse analysis revealed three rhetorical visions and seven functions of dramatizations in the team’s decision making. Visions represented social, righteous, and pragmatic master analogues. The functions of dramatizations were legitimizing independent and current decisions, reinforci…
Exploring User Acceptance of Free Wireless Fidelity Public Hot Spots : An Empirical Study
2008
Research regarding commercial and free wireless fidelity (Wi-Fi) public hot spots acceptance and adoption is sketchy. Therefore, it has become imperative to understand the critical factors that affect their acceptance. The focus of this study is free Wi-Fi public hot spot users, with the objective to better understand their user acceptance. In doing so, this study integrated two well-established initial acceptance models, specifically, the technology acceptance model and the diffusion of innovation theory. This study was conducted using an on-line survey that collected data from 129 users. It uses the Partial Least Square (PLS) technique to examine the relationship between variables. The re…
Extending the Technology Acceptance Model with Personal Innovativeness and Technology Readiness : A Comparison of Three Models
2016
This study concentrates on the role of personal traits in technology acceptance by comparing which of the two personal trait constructs commonly used in IS research, personal innovativeness in the domain of information technology (PIIT) or technology readiness index (TRI), performs better in terms of promoting the explanatory power of the technology acceptance model (TAM). The comparisons are conducted in the case context of online services offered by electric suppliers, and the study is based on the data collected from 1,176 consumers through an online survey and analysed by using structural equation modelling (SEM). The findings of the study show that the inclusion of both PIIT and TRI in…
An Acceptance Model for Useful and Fun Information Systems
2006
Investigating the factors associated with user acceptance of new software systems has been an important research stream in the field of information systems for many years. The technology acceptance model has long been used to examine the acceptance of utilitarian systems. Recently, it has been used to examine recreational or pleasure-oriented systems. Many examples exist of software that, depending on the context of use, can be used for productive and pleasurable interaction. This paper examines the determinants of use of one such “dual” system. A survey of users of a dual system was conducted. Results show that perceived usefulness is more important in determining intention to use than per…
Is it really gender? An empirical investigation into gender effects in technology adoption through the examination of individual differences
2010
A recent development in the technology acceptance literature is the inclusion of gender as a moderator of the relationships between intention and its antecedents, such that some are stronger for men than women, and vice versa. While the effects have been well established, the mechanisms by which they operate, that is, which specific gender differences are in operation and how they affect intention to adopt, have not been thoroughly explored. In this research, psychological constructs with established gender differences, such as core self-evaluations, computer self-efficacy and anxiety, psychological gender-role, and risk-taking propensity, are examined. In addition, this research introduces…
