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…
Economic moralities in self-organised alternative economies : the Finnish cases of ridesharing and timebanking
2020
PurposeThis paper explores economic moralities in self-organised alternative economies and argues that the diverse economies approach is particularly useful in elaborating the self-understandings of such economic communities. The analysis focuses on two types of alternative economies in Finland: ridesharing and timebanking.Design/methodology/approachThrough qualitative data, the paper looks into moments of negotiation where economic moralities of self-organised alternative economies are explicitly debated. The main research data consists of social media conversations, supplemented by a member survey for the participants of the studied timebank. The data are analysed through theory-guided qu…
The formation of long-term unemployed young adults’ emotional capital during childhood : a Bourdieusian approach to emotional harm
2019
This article focuses on the long-term formation of unemployed young adults’ emotional capital and the development of emotional dispositions during childhood. We use Bourdieu’s work and the concept of emotional capital to draw attention to the emotional dynamics of family and peer relations during childhood. Emotional capital is related to parents’ emotional involvement and investment in the child’s well-being, and it encompasses emotional skills and assets that children can attain from family relations. The concept of emotional capital allows an examination of the child’s family and close environment, which shape the development of actors’ emotional inclinations and tendencies. Our data con…
Longitudinal Leisure Activity Profiles and Their Associations with Recovery Experiences and Job Performance
2017
We aimed to identify longitudinal leisure activity profiles among working adults and their links to recovery experiences and job performance. Leisure activities, recovery experiences, and job performance were investigated among 831 employees using survey data collected in spring 2013 (T1) and 2014 (T2). Through latent profile analysis (LPA), four stable longitudinal leisure activity profiles were identified. “Social Sports(wo)men” (46%) engaged in physical and social activities but rarely in creative or cultural activities. “Active Artists” (23%) pursued all leisure activities, particularly creative activities. “Socially & Culturally Inactives” (17%) exercised frequently but seldom engaged …
Electronic Health Records reshaping the socio-technical practices in Long-Term Care of older persons
2020
Electronic Health Records (EHRs) in Long-Term Care (LTC) of older persons are expected to improve resident-centered care by reducing ambiguities in information coordination between LTC workers and organisations. While there are research findings concerning such intended outcomes, we are interested in analysing what sort of other, possibly unanticipated outcomes the use of EHRs in LTC may produce. We argue that the scrutiny of EHRs in LTC requires an understanding of their implementation as socio-technical processes, whereby EHRs are perceived as performative artifacts of LTC rather than technological tools or passive objects. While EHRs have been extensively studied in health-care settings,…
Perceptions of justice influencing community acceptance of spent nuclear fuel disposal : A case study in two Finnish nuclear communities
2019
Final disposal of spent nuclear fuel (SNF) from nuclear power plants (NPPs) is an ethical issue with implications within and across generations. We address this issue from the perspective of nuclear communities that host nuclear waste disposal sites. These are primarily the communities that face injustice due to the potential radiological risks. A resident survey (n = 454) was conducted in two Finnish nuclear communities, i.e. Eurajoki and Pyhäjoki, that are being considered as alternative sites for a second repository for SNF. The nuclear waste management (NWM) company Posiva is already building a repository in Eurajoki, the first in Finland. These communities are in different stages of th…
Varkaus yhteiskunnallisten murrosten näyttämönä 1900-luvun alusta nykypäivään
2020
Tässä kymmenestä artikkelista koostuvassa kokoomateoksessa tarkastellaan Varkautta rakennemuutoksen kanssa kamppailevana pienenä kaupunkina historiallisia dokumentteja sekä vuosina 2016–2017 kerättyjä kysely- ja haastatteluaineistoa hyödyntäen. Pitkän teollisuushistorian omaava Varkauden kaupunki on tämän vuosituhannen ensimmäisinä vuosikymmeninä menettänyt suuren osan teollisista työpaikoistaan ja sen väestö on supistunut voimakkaasti. Kuitenkin koko aikuisväestöä edustava kysely kertoo, että varkautelaiset ovat tyypillisesti tyytyväisiä työhönsä, sosiaalisiin suhteisiinsa ja elämäänsä muutenkin. Varkaus nähdään turvallisena ja hyvän elämän puitteet tarjoavana asuinpaikkana. Hyvinvoinnin t…
Bayesian models for data missing not at random in health examination surveys
2018
In epidemiological surveys, data missing not at random (MNAR) due to survey nonresponse may potentially lead to a bias in the risk factor estimates. We propose an approach based on Bayesian data augmentation and survival modelling to reduce the nonresponse bias. The approach requires additional information based on follow-up data. We present a case study of smoking prevalence using FINRISK data collected between 1972 and 2007 with a follow-up to the end of 2012 and compare it to other commonly applied missing at random (MAR) imputation approaches. A simulation experiment is carried out to study the validity of the approaches. Our approach appears to reduce the nonresponse bias substantially…
Deflation-based separation of uncorrelated stationary time series
2014
In this paper we assume that the observed pp time series are linear combinations of pp latent uncorrelated weakly stationary time series. The problem is then to find an estimate for an unmixing matrix that transforms the observed time series back to uncorrelated time series. The so called SOBI (Second Order Blind Identification) estimate aims at a joint diagonalization of the covariance matrix and several autocovariance matrices with varying lags. In this paper, we propose a novel procedure that extracts the latent time series one by one. The limiting distribution of this deflation-based SOBI is found under general conditions, and we show how the results can be used for the comparison of es…
