Relationship between different domains of physical activity and positive mental health among young adult men
2020
Abstract Background There is growing evidence on positive effects of physical activity (PA) on mental health. However, the focus of previous research on this relationship has typically been on mental health from the perspective of mental health problems rather than from the perspective of mental wellbeing. Further, previous research has commonly focused rather on leisure time PA without evidence on the role of other domains of PA. The aim of the present cross-sectional study was to investigate the relationship between positive mental health (PMH) and different domains of PA in young Finnish men. The secondary aim was to examine the reasons for physical inactivity among individuals with a lo…

Viihtymistä, kontakteja ja hyötyä : sähköiset mediat kuudesluokkalaisen silmin
2009
Media on nykypäivänä suuri ja alati kasvava osa elämäämme, ja lapset ja nuoret ovat sen käytössä edelläkävijöitä. Tämän tutkimuksen tarkoituksena olikin selvittää, minkälaisia merkityksiä sähköisillä medioilla (tietokone/internet, elektroniset pelit, televisio ja kännykkä) on yhden kuudennen luokan oppilaille. Tutkimuksessa tarkasteltiin myös, mitä sähköisiä medioita tutkimuksessa mukana olevat lapset käyttävät ja miten. Tutkimuksessa käytettiin menetelmien ja aineistojen triangulaatiota, jolloin tutkimuksessa yhdistyivät sekä laadullinen että määrällinen tutkimus. Käytettyjä tutkimusaineistoja olivat kyselylomakkeet, mediakirjoitelmat, päiväkirjat ja posterit. Kirjoitelmia ja postereita lä…
Cycling but not walking to work or study is associated with physical fitness, body composition and clustered cardiometabolic risk in young men
2020
IntroductionActive commuting is an inexpensive and accessible form of physical activity and may be beneficial to health. The aim of this study was to investigate the association of active commuting and its subcomponents, cycling and walking, with cardiometabolic risk factors, physical fitness and body composition in young men.MethodsParticipants were 776 Finnish young (26±7 years), healthy adult men. Active commuting was measured with self-report. Waist circumference was measured and body mass index (BMI) calculated. Aerobic fitness was measured with bicycle ergometer and muscular fitness with maximal leg and bench press, sit-ups, push-ups and standing long jump. Cardiometabolic risk factor…
Modelling Mobile Encounter Networks
2006
This article presents mobile encounter networks, which emerge when mobile devices come across each other and form a temporary connection between them using a common short-range radio technology. Local information exchanges between mobile devices results in a broadcast diffusion of information to other users of the network with a delay. In addition to presenting the concept of mobile encounter networks, we also provide an abstract method for describing the information diffusion process inside them. peerReviewed
The emission reduction potential of electric transport modes in Finland
2021
The transportation sector has become the fastest growing source of greenhouse gas (GHG) emissions. One solution to mitigate the impacts is a shift towards electric modes. Where previous studies have only focused on the replacement of individual modes, our study presents a more holistic approach by comparing land-based, water-based and airborne transportation modes. We study the GHG emission reduction potentials of electric cars, buses, trains, ferries and aircraft in comparison to existing modes on 34 routes within Finland and across the Baltic Sea to Sweden and Estonia. By comparing the GHG emissions in carbon dioxide equivalents (CO2-eq) per passenger kilometer for each mode, we also cons…
'Foreign Readers and the Imperishable Troll' : travelling to locations with connections to Tove Jansson and her works
2022
The following piece is based on the lectio praecursoria presented at the defense of the doctoral dissertation ‘Ideal Absence and Situated Readers: Experiencing Space Through Connection to Tove Jansson and her Works’ which was publicly discussed on November 3, 2021, at the University of Jyväskylä. The full version of the dissertation can be found at: http://urn.fi/URN:ISBN:978-951-39-8861-6. peerReviewed
Associations of active commuting to school in childhood and physical activity in adulthood
2023
AbstractThis study examined whether active commuting to school in childhood and adolescence predicted active commuting to work and overall physical activity (PA) in adulthood. Participants from the Young Finns Study (N = 2436) were aged 9–18 years in 1980 and followed up until 2018/2020. Their commuting modes to school were assessed with a self-reported questionnaire in 1980. Adulthood PA was assessed through self-reports regarding commuting modes to work (2001–2018), leisure-time physical activity (LTPA) (2001–2018), and objectively measured daily steps (2007–2018/2020). Associations between childhood commuting and adulthood PA were evaluated using regression analyses and multilevel models…
The Carbon Footprint of Volunteer Tourism
2019
Abstract Tourism is growing at a fast rate and so is its carbon footprint. Alongside conventional tourism, a new form of tourism, so-called voluntourism, has emerged. The discussion on voluntourism in the existing literature has hereby mainly centred around its positive impacts on the health and education of communities and the local environment in developing countries. Nevertheless, little attention has been drawn to its climate impacts. This study set out to investigate the carbon footprint of voluntourism. The data were collected at a local non-governmental organisation (NGO) in India working with voluntourists. Both the carbon footprint of the stay in India and that from the round trip …
Adapting Downlink Power in Fronthaul-Constrained Hierarchical Software-Defined RANs
2017
Abstract The proof-of-concept software-defined radio access network (RAN) is not flexible enough due to the inherent delay and the necessity of high-capacity fronthaul links. We are hence motivated to propose a hierarchical software-defined RAN architecture, over which the base stations (BSs) are abstracted into multiple virtual local controllers while these local controllers are administered by a high-level controller. Under such a hierarchical network architecture, we particularly investigate in this paper how to adapt the BS transmit power over a long term according to the network dynamics under the constraints of mobile user queue stability and limited fronthaul capacity. We first formu…
