Age, pathogen exposure, but not maternal care shape offspring immunity in an insect with facultative family life
2017
International audience; Background: To optimize their resistance against pathogen infection, individuals are expected to find the right balance between investing into the immune system and other life history traits. In vertebrates, several factors were shown to critically affect the direction of this balance, such as the developmental stage of an individual, its current risk of infection and/or its access to external help such as parental care. However, the independent and/or interactive effects of these factors on immunity remain poorly studied in insects.Results: Here, we manipulated maternal presence and pathogen exposure in families of the European earwig Forficula auricularia to measur…

Skriftliga språkkunskaper i A-svenska hos finska abiturienter på basis av processbarhetsteori
2016
Tämän tutkimuksen tarkoituksena oli tutkia suomenkielisten, ruotsin kielen pitkää oppimäärää opiskelevien abiturienttien kirjallista kielitaitoa lukio-opintojen loppuvaiheessa. Tutkimushenkilöt (n=12) olivat aloittaneet ruotsin kielen opiskelun alakoulun 3.–5. vuosiluokalla ja valmistautuivat tutkimushetkellä ruotsin kielen pitkän oppimäärän ylioppilaskirjoituksiin. Tutkimuksen pohjana käytettiin Pienemannin prosessoitavuusteoriaa (1998). Tutkittavat kieliopilliset rakenteet olivat inversio väitelauseessa, jälkilauseen sanajärjestys, kieltosanan paikka sivulauseessa, epäsuora kysymys sekä adjektiivi attributiivisena ja predikatiivisena lauseenjäsenenä. Tutkimuksen tulokset osoittavat, että …
Accelerometer-based osteogenic indices, moderate-to-vigorous and vigorous physical activity, and bone traits in adolescents
2022
Objectives: We investigated the associations of accelerometry-derived osteogenic indices (OIs), moderate-to-vigorous (MVPA), and vigorous intensity physical activity (VPA) with peripheral quantitative computed tomography (pCQT) parameters in 99 adolescents aged 10–13 years. Methods: Bone parameters were assessed at the distal (4%) and shaft (66%) of the tibia using pQCT. Accelerometers were worn on the right hip for 7 consecutive days. OIs were calculated based on acceleration peak histograms either using all of the peaks (OI) or peaks with acceleration ≥5.2 g (HOI). MVPA and VPA were defined using previously published cut-points. Results: HOI was positively associated with total area (Part…
Relationship between occupational and leisure-time physical activity and the need for recovery after work
2023
Abstract Background Health benefits of physical activity are very well acknowledged but the role of both occupational physical activity (OPA) and leisure time physical activity (LTPA) in recovery after work is not thoroughly understood. The purpose of this study was to investigate the association between accelerometer-measured OPA and LTPA and the need for recovery after work (NFR) in early childhood education and care (ECEC) professionals. Methods The study participants were 217 female ECEC professionals aged 17–64. Physical activity was recorded with a three-axis accelerometer (ActiGraph GT9X Link, ActiGraph, USA) for seven consecutive days. Separate analyses were conducted for both OPA a…
Dropout intentions in secondary education : Student temperament and achievement motivation as antecedents
2023
Introduction As early school leaving and dropping out from education pose a challenge for later life adjustment, it is important to identify antecedent factors for the risk of school dropout to tailor individual support for adolescents. Consequently, this study examines the role of adolescents' motivational beliefs and behaviors (i.e., success expectations, planning, and task-avoidance) as well as their temperament (i.e., extraversion/surgency, negative affectivity, effortful control, and affiliativeness) in their dropout intentions in the first year of upper secondary education. Methods Participants were Finnish adolescents' (n = 536; 57% girls, mean age 12.39 at outset, standard deviation…

“At worst it leads to madness.” A phenomenographic approach on how early childhood education professionals experience emotions in teamwork
2022
Teamwork is a key part of almost any person’s working life. At its best, teamwork embodies a good team spirit and increases employee well-being, but at its worst, a team is characterized by mistrust or competition between members where action and development is not possible. In this study we explored what types of emotions early childhood education professionals experience during teamwork. These questions are answered with the help of a phenomenographic approach. As a theoretical frame, in this study, we utilize Warr’s (2012) Affective circumplex model. According to our results the ECE professional’s experienced emotions can be mostly described through the categories of enthusiasm, anxiety,…
