Aineenopettajaksi opiskelevien koulukokemuksia sukupuolistuneesta väkivallasta
2022
Artikkelissa tarkastelemme sukupuolistunutta väkivaltaa aineenopettajaopiskelijoiden koulukokemusten näkökulmasta. Merkittävä määrä nuorista altistuu väkivallan ja häirinnän eri muodoille. Kouluterveyskyselyjen mukaan erityisesti tyttöihin ja sukupuolivähemmistöihin kohdistuva väkivalta ja seksuaalinen häirintä ovat viime vuosien aikana lisääntyneet huolestuttavasti. Koulun ja opettajien rooli ilmiöön puuttumisessa on tärkeä, samoin opettajankoulutuksen, jonka aikana opiskelijoiden olisi tärkeä tulla tietoiseksi väkivallan ilmenemismuodoista ja niihin puuttumisen mahdollisuuksista. Tutkimuksen aineisto kerättiin fokusryhmähaastatteluilla, joihin osallistui yhteensä 18 aineenopettajaopiskeli…

Is a seminar based on student-created screen capture videos a meaningful way of learning?
2008
We ran a problem-based seminar with screen capture videos. The students worked in small groups of two or three students or they completed the coursework individually. In this seminar the students had a workspace in the Optima environment for publishing their coursework videos. At the final phase of the course the students were expected to familiarize themselves with the presentations of other groups. In this paper we analyze the benefit of our problem-based coursework on the web by comparing the different phases of it. After each phase the students were expected to analyze the benefit of it for their learning. peerReviewed
Screen-based activities and physical complaints among adolescents from the Nordic countries
2010
BACKGROUND: A positive association between time spent on sedentary screen-based activities and physical complaints has been reported, but the cumulative association between different types of screen-based activities and physical complaints has not been examined thoroughly. METHODS: The cross-sectional association between screen-based activity and physical complaints (backache and headache) among students was examined in a sample of 31022 adolescents from Denmark, Sweden, Norway, Finland, Iceland and Greenland, as part of the Health behaviour in school-aged children 2005/06 (HBSC) study. Daily hours spent on screen-based activities and levels of physical complaints were assessed using self-r…
Towards a framework for assessment and management of cumulative human impacts on marine food webs
2015
Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…
Medición del gasto energético en una muestra de escolares adolescentes valencianos mediante acelerometría
2011
Este estudio representa el trabajo más reciente de los desarrollados dentro de la línea de investigación de ‘Actividad física y salud’ que mantiene el grupo en el que se sitúa este estudio: Unidad de Investigación de Teoría y Pedagogía de la Actividad Física y el Deporte. Esta investigación se ha realizado conjuntamente entre la Universidad de Valencia y el Instituto de Educación Secundaria Nº1 de Cheste, Valencia. Dicho Instituto tiene la peculiaridad de albergar a estudiantes pertenecientes al Plan de Especialización Deportiva (PED). El objetivo principal es conocer el gasto energético tanto de los adolescentes pertenecientes al PED como los que no, en el ciclo educativo al que pertenecen…
Medición objetiva y percepción subjetiva de los niveles de actividad física en una muestra de niños escolares
2015
El sedentarismo durante la infancia y adolescencia repercute directamente en los niveles de salud de la población. La actividad física se relaciona con una disminución del riesgo de obesidad e hígado graso y mejoría del perfil cardiometabólico en general, mayor masa ósea y fuerza muscular, e incremento en el desarrollo cognitivo a edades tempranas. Con este fin se ha recomendado la práctica de actividad física de intensidad moderada y/o vigorosa al menos durante 60 minutos diarios en niños mayores de 5 años, habiéndose desarrollado diversas guías para población infantil. Diferentes estudios demuestran unos niveles de sedentarismo altos siendo las niñas más sedentarias que los niños, y un cu…
Comparison of pre- and post-intervention levels of physical activity among sedentary Finnish mothers
2010
Weldon T. Green and Elizaveta Novoradovskaya, 2012. Comparison of pre- and post-intervention levels of physical activity among sedentary Finnish mothers. Master’s Thesis in Sport and Department of Sport Sciences. University of Jyvaskyla. 39 p. The 1990’s marked a shift in the academic understanding of health-enhancing physical activity that was different from the exercise-based physical fitness paradigm that ruled public health policy at the time. Since then, lifestyle physical activity has been incorporated into physical activity recommendations worldwide and recognized medically and culturally for its impact on many chronic health conditions. Lifestyle physical activity interventions (LPA…
Dual processing approach to sedentary behavior and physical activity in the workplace
2023
Regular physical activity is an important health promoting behavior. Yet, many adults live sedentary lifestyles, especially during their workday. The current study applies an extended theory of planned behavior model, incorporating affective attitudes and instrumental attitudes, along with habit, to predict limiting sedentary behavior and physical activity within an office environment. Theory of planned behavior constructs and habit were assessed with an online survey on a sample of 180 full-time office workers, with self-reported behavior assessed 1 week later (Mage = 25.97, SDage = 10.24; 44 males, 134 females, and 2 nonbinary). Model fit was indicated by BRMSEA (M = 0.057, SD = 0.023), B…
Revisiting the cross‐sectional and prospective association of physical activity with body composition and physical fitness in preschoolers: A composi…
2022
Background Information is limited for the benefits of physical activity (PA) in preschoolers. Previous research using accelerometer-assessed PA may be affected for multicollinearity issues. Objectives This study investigated the cross-sectional and prospective associations of sedentary behaviour (SB) and PA with body composition and physical fitness using compositional data analysis. Methods Baseline PA and SB were collected in 4-year-old (n = 315) using wrist-worn GT3X+ during seven 24 h-periods. Body composition (air-displacement plethysmography) and physical fitness (PREFIT test battery) were assessed at baseline and at the 12-month follow-up. Results Increasing vigorous PA at expenses o…
