Effects of a School-Based Intervention on Motivation for Out-of-School Physical Activity Participation
2021
Purpose: We tested the effects of an autonomy-supportive intervention in physical education (PE) on high-school students’ autonomous motivation in PE, and their autonomous motivation, intentions, and physical activity (PA) behavior in a leisure time guided by the trans-contextual model. Method: PE classes in two schools were assigned to receive either an autonomy-supportive intervention and/or a control intervention via random allocation by the school. The PE teacher of the school assigned to the autonomy-supportive intervention was trained to provide autonomy support while the PE teacher of the school assigned to the control intervention received no training. Students (N = 256) in all clas…
Formation and Mitigation of Technostress in the Personal Use of IT
2022
Understanding information technology (IT) use is vital for the information systems (IS) discipline due to its substantial positive and negative consequences. In recent years, IT use for personal purposes has grown rapidly. Although personal use is voluntary and can often reflect fun, technostress is a common negative consequence of such use. When left unaddressed, technostress can cause serious harm to IT users. However, prior research has not explained how technostress forms over time or how its mitigation takes place in a personal—rather than organizational—environment. To address these research gaps, we conducted a qualitative study with narrative interviews of IT users who had experienc…
Preventing occupational injury among police officers: does motivation matter?
2017
Background: Injury prevention is an important issue for police officers, but the effectiveness of prevention initiatives is dependent on officers’ motivation toward, and adherence to, recommended health and safety guidelines. Aims: To understand effects of police officers’ motivation to prevent occupational injury on beliefs about safety and adherence to injury prevention behaviours. Methods: Full-time police officers completed a survey comprising validated psychometric scales to assess autonomous, controlled and amotivated forms of motivation (Treatment Self-Regulation Questionnaire), behavioural adherence (Self-reported Treatment Adherence Scale) and beliefs (Safety Attitude Questionnaire…
Toward a stage theory of adaptive social media use : explaining change in facebook use
2018
Existing research on information technology (IT) use has shown that post- adoptive technology use is not a stable but a dynamic phenomenon in which users apply various adaptation behaviors. Users reshape the technology (IT adaptation), adjust their work routines (task adaptation), and change their own behavior (user adaptation) according to the changes induced by IT. Today, people use increasingly social media and other IT for personal purposes. Facebook (FB) is a good example of personal IT that people voluntarily use for years and has become an integral part of people’s everyday lives. Despite extensive research on IT use and IT/user adaptation, we know little about the dynamics of post-a…

Sosioemotionaalisten taitojen tukeminen sosiodraamaan perustuvassa lasten toiminnallisessa pienryhmässä
2012
Tässä tutkimuksessa tarkasteltiin lasten sosioemotionaalisten taitojen kehittymistä lasten toiminnallisessa pienryhmässä. Pienryhmään kuului seitsemän (7) lasta ja sen toiminta perustui sovellettuun sosiodraamaan. Sosioemotionaalisten taitojen alueelta tarkasteltaviksi taidoiksi määrittyivät lasten kehitystarpeiden mukaan itsesäätely, tunteiden säätely, omien tunteiden tunnistaminen sekä empatiataito. Lisäksi selvitimme siirtyvätkö ryhmässä opitut taidot ryhmän ulkopuolelle kouluympäristöön ja miksi ryhmään osallistuneet lapset hyötyivät ryhmän toiminnasta eri tavoin. Tutkimus toteutettiin laadullisena tapaustutkimuksena, joka sisälsi toimintatutkimuksen piirteitä. Osallistuimme pienryhmään…
The effects of inbreeding on mating success and offspring production of males and females in a Drosophila littoralis population
2011
Sisäsiitoksella, eli pariutumisella lähisukulaisten kesken, on monia negatiivisia vaikutuksia sekä populaation että yksilön kelpoisuudelle. Sisäsiitos lisää homotsygotiaa ja mahdollistaa siten väistyvien haitallisten mutaatioiden ilmentymisen fenotyypissä sekä estää heterotsygotiasta johtuvaa paremmuutta lokuksissa, joissa on ylidominanssia. On osoitettu, että sisäsiittoisuus voi vaikuttaa koiraisiin ja naaraisiin eri tavalla siten, että toinen sukupuolista kärsii sisäsiitoksesta toista enemmän. Jotkut tutkimukset ovat näyttäneet, että sisäsiittoisuudella on voimakkaampi negatiivinen vaikutus koiraiden kuin naaraiden lisääntymiskykyyn, kun taas toiset osoittavat että naaraat kärsivät enemmä…

The adaptations to tube-dwelling life of Propsilocerus akamusi (Diptera: Chironomidae) larvae and its eutrophication-tolerant mechanisms
2019
Propsilocerus akamusi (Diptera: Chironomidae) is a dominant macroinvertebrate species in many eutrophic lakes in subtropical and temperate zones. P. akamusi larvae can migrate deep into the sediment (>30 cm) during summer where is no oxygen. However, to our knowledge, the specific adaptive tactics of its tube-dwelling life (>30 cm) and underlying mechanisms why this species is favored by nutrient-rich lakes remain limited. With the understanding above-mentioned issues, we can provide important information for the development of sensitive biomonitoring. We examined monthly morphological dynamics and physiological adaptations of P. akamusi to anoxic conditions, and environmental relationships…
