Work Ability of Finnish Physical Education Teachers

2015

In the physical education (PE) teachers’ profession, physical tasks comprise a large part of the job. PE teachers identify their health as good, and they are satisfied with their job. Nevertheless, the work ability of PE teachers may be decreasing. Purpose: The purpose of this article was to explore the work ability of Finnish PE teachers. What disorders or physical problems do PE teachers experience as a result of their job, and how do they affect job satisfaction? Are there differences between men and women or older and younger teachers? Of the Finnish PE teachers (N = 655), 31% reported that they had at least one disease or disorder that hindered their work ability. The most common were …

EMBEDDING CONTEXT IN INVESTIGATIONS OF AFFECTIVE VARIABILITY: AGE DIFFERENCES IN AFFECT-HEALTH LINKS

2017

Context plays a potentially important role in explaining variability in affective experiences and yet, has often been overlooked in this line of research. The current study used data from a lifespan sample of 398 German participants ranging between 12–88 years of age (M = 40, SD = 20). Participants completed computer assisted personal interviews regarding health and well-being measures, as well as experience sampling assessments of daily affective experiences and events (e.g., uplifts). Three indices of positive affect (PA) were created: mean PA, PA reactivity to uplifts, and PA variability. In general, greater mean PA and lower PA reactivity and variability were associated with better heal…

In this paper we study the accuracy of the finite difference method when the finite difference method is applied to approximately analyze the structure.

Gender differences in child and adolescent daily activities : a cross-national time use study

2021

This study used 2009–2015 time-diary data to examine gender differences in daily activities among children and adolescents aged 10–17 in Finland, Spain and the UK ( N = 3517). In all three countries, boys were significantly more involved in screen-based activities and exercising and girls in domestic work, non-screen educational activities and personal care. Gender differences in socializing time were only significant in the UK, with girls socializing more than boys. Gender gaps within countries were largest in domestic work (UK: 60%; Finland: 58%; Spain: 48%) and exercising (UK: 57%; Finland: 36%; Spain: 27%), followed by educational time (UK: 35%; Finland: 34%; Spain: 18%) and screen-bas…

Value preserving portfolio strategies and the minimal martingale measure

1998

We consider some relations between the minimal martingale measure and the value preserving martingale measure in a continuous-time securities market. Under the assumption of continuous share prices we show that under a structure condition both these martingale measures exist and indeed coincide. This however does not mean that the corresponding concepts of value preserving portfolio strategies and (local) risk minimisation in the area of option hedging in incomplete markets are identical.

Is lithium implicated in tobacco addiction?

2016

IntroductionTobacco is a source of mineral elements that can affect human health in various ways, such as lithium, which is used as a psychiatric medication. Lithium salts are used as mood-stabilizing drugs and indicated in the treatment of manic-depressive psychosis.ObjectiveStudying the lithium content in tobacco over the smokers’plasma content and evaluate the potential role of lithium in tobacco addiction.MethodsA total of 18 different tobacco products (cigarettes, smokeless and water pipe tobacco) and 125 plasma samples (45 from smokers, 10 from ex-smokers and 70 from non-smokers) were collected to determinate the lithium content. Tobacco samples were digested with nitric acid and lith…

The perception of food products in adolescents, lay adults, and experts:A psychometric approach

2022

Almost 40% of global mortality is attributable to an unhealthy diet, and adolescents and young adults are particularly affected by growing obesity rates. How do (young) people conceptualize and judge the healthiness of foods and how are the judgments embedded in people’s mental representations of the food ecology? We asked respondents to rate a large range of common food products on a diverse set of characteristics and then applied the psychometric paradigm to identify the dimensions structuring people’s mental representations of the foods. Respondents were also asked to rate each food in terms of its healthiness, and we used the foods’ scores on the extracted dimensions to predict the heal…

Factors psicosocials rellevants en la violència de preadolescents i adolescents escolaritzats

2010

A pesar de la considerable evidència acumulada sobre els efectes de la violència en els mitjans, encara hi ha controvèrsia sobre el tema. La comunitat científica debat la influència de la TV i els videojocs en el comportament dels subjectes (vid. Kids, TV viewing, andaggressivebehavior, Science (Letters) 297, 49-50, 2002). Aquells que s'oposen al fet que la TV i els videojocs tenen influència sobre el comportament agressiu, defensen que la causalitat no es pot establir tan fàcilment, ja que als individus violents els agradarà més veure actes agressius en TV i que estiguen presents en els videojocs. En l'actual estudi realitzat amb escolars preadolescents i adolescents 'amb una grandària de …
