Gradient Estimate for Solutions to Poisson Equations in Metric Measure Spaces
2011
Let $(X,d)$ be a complete, pathwise connected metric measure space with locally Ahlfors $Q$-regular measure $\mu$, where $Q>1$. Suppose that $(X,d,\mu)$ supports a (local) $(1,2)$-Poincar\'e inequality and a suitable curvature lower bound. For the Poisson equation $\Delta u=f$ on $(X,d,\mu)$, Moser-Trudinger and Sobolev inequalities are established for the gradient of $u$. The local H\"older continuity with optimal exponent of solutions is obtained.
Self-Efficacy, Planning, or a Combination of Both? A Longitudinal Experimental Study Comparing Effects of Three Interventions on Adolescents’ Body Fat
2016
Author(s): Luszczynska, Aleksandra; Hagger, Martin S; Banik, Anna; Horodyska, Karolina; Knoll, Nina; Scholz, Urte | Abstract: BackgroundThe superiority of an intervention combining two sets of theory-based behavior change techniques targeting planning and self-efficacy over an intervention targeting planning only or self-efficacy only has rarely been investigated.PurposeWe compared the influence of self-efficacy, planning, and self-efficacy+planning interventions with an education-based control condition on adolescents' body fat, assuming mediating effects of respective social cognitive variables and moderate-to-vigorous physical activity (MVPA). The moderating role of the built environment…
Predictors of school students’ leisure-time physical activity : An extended trans-contextual model using Bayesian path analysis
2021
Abstract Background:The trans-contextual model (TCM) has been applied to identify the determinants of leisure-time physical activity participation in secondary school students. In the current study, the TCM was extended to include additional constructs that represent non-conscious, implicit processes that lead to leisure-time physical activity participation alongside the motivational and social cognition constructs from the TCM. The current study used baseline and follow-up data from an intervention study to test the extended TCM.Methods:The current study adopted a two-wave prospective design. Secondary-school students (N = 502) completed measures of perceived autonomy support from physical…
Early mathematical skill profiles of prematurely and full-term born children
2017
Abstract Preterm birth is associated with low mathematical skills in children. This study on five-year-old Finnish children investigated whether mathematical skill profiles would differ between prematurely and full-term born children and how such profiles and other cognitive skills would be related. Mathematical skills included digit knowledge, spontaneous focusing on numerosity, arithmetic, counting and geometric skills. The investigated cognitive skills were phonological processing, working memory, instruction comprehension, speeded naming, inhibition and visuomotor skills. The participants were 119 preterm children with birth weight
Rethinking age in athletic retirement: An existential-narrative perspective
2015
The aim of this paper is to examine theoretical understandings of athletic career and career termination from an existential-narrative perspective. Our critical analysis suggests that career models and many research texts have an implicit understanding of sport as a profession and propose a normative end to the career when athletes no longer improve their results. Being framed by Western cultural narratives of ageing as decline, the aforementioned career models disregard athletes’ subjective careers and their agency in bringing meaning to experiences of ageing and decline in athletic performance. While the main focus of this paper is on theoretical analysis, some empirical findings from our…
The effect of physical education students' beliefs and values on their physical activity: A growth mixture modelling approach
2013
This study examined the change in adolescents' expectancy-related beliefs and task values towards physical education (PE). In addition, the physical activity (PA) growth trajectories of the identified adolescent subpopulations were examined. This study comprised 812 students (age M = 12.31, range: 11–13), who answered questionnaires four times during Grades 6–9. This study found that expectancy-related beliefs declined, while task values increased across the middle school transition. Adolescents who valued PE highly and experienced an increase in their expectancy-related beliefs became physically more active across time, while adolescents with the lowest levels and the most negative change …
Foreign language pronunciation skills and musical aptitude A study of Finnish adults with higher education
2010
Abstract The main aim of this study was to examine second language production and discrimination skills in the light of musical aptitude. Our study was conducted in university settings in south-western Finland. English was used as a model for the second language due to its popularity among young adults. There were three types of tests used in this study: a pronunciation test, a phonemic listening discrimination task, and the Seashore test as an index of the musical aptitude. All the participants performed equally well in the phonemic listening discrimination task. However, the participants with higher musical aptitude were able to pronounce English better than the participants with less mus…
Relationships among perceived motivational climate, motivational regulations, enjoyment, and PA participation among Finnish physical education studen…
2015
The influence of teacher-initiated motivational climate on cognitive, affective, and behavioural student outcomes has been highlighted as an area of future research. This study, grounded in self-determination and achievement goal theories, examined how teacher-initiated motivational climate can increase student motivation and positive affective responses in physical education (PE) along with their physical activity (PA) participation, and whether motivational climate has a longitudinal effect across middle school. In addition, we aimed to examine the role of positive affect in explaining the relationship between motivation in PE and out-of-school PA participation. Our sample comprised 540 a…
El Trabajo Social, sus imágenes y su público. La construcción de una identidad colectiva.
2003
El objeto de esta tesis, consiste en responder a una cuestión ¿cuál es el lugar del Trabajo Social? desde un orden simbólico. Partimos desde la perspectiva teórica del construccionismo, presentamos un planteamiento epistemológico que implica la transición del Trabajo Social como un medio (profesión) hacia el Trabajo Social como un fin (disciplina), llevamos la investigación al espacio de un caso (serie de televisión), buscamos como analizar las representaciones sociales del Trabajo Social, a través de sus imágenes y de la influencia social de su público (audiencia).Para materializar este propósito definimos en la primer parte, los tres elementos teóricos más relevantes del objeto. En primer…
Sosiaalialan asiakastietojärjestelmissä paljon parannettavaa: käyttäjäkokemukset 2019
2020
Sosiaali- ja terveydenhuollon digitalisaatiolle on asetettu paljon odotuksia niin palveluiden laadun, saavutettavuuden kuin tehokkuuden osalta. Asiakas- ja potilastietojärjestelmiltä odotetaan paljon tavoitteiden saavuttamiseksi. Asiakastietojärjestelmät ovat laajasti käytössä sosiaalialalla, mutta niiden käyttöä työvälineenä ja niiden avulla saavutettuja hyötyjä on tutkittu ammattilaisten näkökulmasta vain vähän. Keväällä 2019 kartoitettiin ensimmäistä kertaa valtakunnallisesti sosiaalialan ammattilaisten käyttäjäkokemuksia asiakastietojärjestelmistä. Tässä artikkelissa kuvataan kyselytutkimuksen toteutus ja tulokset eniten käytettyjen tuotemerkkien osalta. Tutkimus toimii pilottina vuonna…
