»just de niillä oli sovmorgon» : Kulturella och pragmatiska aspekter på kodväxling i tvåspråkiga ungdomssamtal i Haparanda, Stockholm och Helsingfors

2017

The aim of the study is to explore situational, cultural and pragmatic factors that might trigger code-switching during informal conversations outside of the classroom at school among bilingual adolescents in Haparanda, Helsinki and Stockholm. An attempt is made to clarify different functions of code-switching, i.e. why bilingual adolescents code-switch from Swedish to Finnish and vice versa. The conversational data, consisting of video-recorded group and pair conversations, was collected in 2014–2015 at six junior high schools in Haparanda, Helsinki and Stockholm. The analysis of the data is qualitative. The theoretical framework is found in the field of translanguaging, which aims to desc…

The role of ethical organizational culture in preventing sickness absence and turnover in organizations

2016

This research examined the role of ethical organizational culture in preventing sickness absence and turnover in organizations, and also validated the Corporate Ethical Virtues (CEV) model used to study ethical organizational culture. More specifically, the research had four aims: 1) to test the factorial validity and group invariance of the 58-item CEV scale, 2) to examine the associations between ethical organizational culture and sickness absence at the individual and work unit levels, 3) to study the role of ethical organizational culture as an antecedent of managerial turnover, and 4) to examine the reasons managers gave for their turnover, and the associations between ethical culture …

Bokläsningssituationer hos tvåspråkiga familjer

2015

Tämän tutkielman tarkoituksena on tutkia suomalaisten kaksikielisten perheiden kirjanlukutilanteita. Kielinä perheissä ovat suomi ja ruotsi. Kiinnostuksen pääasiallisina kohteina ovat vanhempien ja lasten kielenkäyttö, lukutilanteiden rakentuminen, lasten osallistaminen lukutilanteessa ja kieleen liittyvät keskustelut lukuhetken aikana. Tutkielman aineisto on kerätty Jyväskylän yliopiston Child2ling-tutkimusprojektin yhteydessä. Projektissa tutkitaan kaksikielisiä perheitä kolmella eri paikkakunnalla Suomessa, ja tutkimusta tehdään monitahoisin menetelmin. Tässä tutkielmassa käytetty aineisto sisältää viiden perheen itse videokuvaamia kirjanlukutilanteita, jotka tutkimustyöntekijät ovat lit…

Predicting the age at natural menopause in middle-aged women

2021

Objective To predict the age at natural menopause (ANM). Methods Cox models with time-dependent covariates were utilized for ANM prediction using longitudinal data from 47 to 55-year-old women (n = 279) participating in the Estrogenic Regulation of Muscle Apoptosis study. The ANM was assessed retrospectively for 105 women using bleeding diaries. The predictors were chosen from the set of 32 covariates by using the lasso regression (model 1). Another easy-to-access model (model 2) was created by using a subset of 16 self-reported covariates. The predictive performance was quantified with c-indices and by studying the means and standard deviations of absolute errors (MAE ± SD) between the pre…

Hormone replacement therapy enhances IGF-1 signaling in skeletal muscle by diminishing miR-182 and miR-233 expressions: A study on postmenopausal mon…

2014

MiRNAs are fine-tuning modifiers of skeletal muscle regulation, but knowledge of their hormonal control is lacking. We used a co-twin case–control study design, that is, monozygotic postmenopausal twin pairs discordant for estrogen-based hormone replacement therapy (HRT) to explore estrogen-dependent skeletal muscle regulation via miRNAs. MiRNA profiles were determined from vastus lateralis muscle of nine healthy 54–62- years-old monozygotic female twin pairs discordant for HRT (median 7 years). MCF-7 cells, human myoblast cultures and mouse muscle experiments were used to confirm estrogen’s causal role on the expression of specific miRNAs, their target mRNAs and proteins and finally the ac…

Cross-sectional associations between cardiorespiratory fitness and NMR-derived metabolic biomarkers in children : the PANIC study

2022

Objective: Cardiorespiratory fitness has been inversely associated with cardiovascular risk across the lifespan. Some studies in adults suggest that higher cardiorespiratory fitness is associated with cardioprotective metabolite profile, but the evidence in children is lacking. Therefore, we investigated the cross-sectional association of cardiorespiratory fitness with serum nuclear magnetic resonance derived metabolic biomarkers in children. Methods: A population sample of 450 children aged 6–8 years was examined. Cardiorespiratory fitness was assessed by a maximal exercise test on a cycle ergometer and quantified as maximal power output normalised for lean body mass assessed by dual-energ…

Genetic diversity in populations of asexual and sexual bag worm moths (Lepidoptera: Psychidae)

2005

BACKGROUND: Despite the two-fold cost of sex, most of the higher animals reproduce sexually. The advantage of sex has been suggested to be its ability, through recombination, to generate greater genetic diversity than asexuality, thus enhancing adaptation in a changing environment. We studied the genetic diversity and the population structure of three closely related species of bag worm moths: two strictly sexual (Dahlica charlottae and Siederia rupicolella) and one strictly asexual (D. fennicella). These species compete for the same resources and share the same parasitoids. RESULTS: Allelic richness was comparable between the sexual species but it was higher than in the asexual species. Al…

Akillesjänteen ja luustolihaksen glukoosin käyttö fyysisen rasituksen aikana positroniemissiotomografialla mitattuna

2001

Jarna Saarinen. Akillesjänteen ja luustolihaksen glukoosin käyttö fyysisen rasituksen aikana positroniemissiotomografialla mitattuna. Liikuntafysiologian Pro Gradu -tutkielma. Liikuntabiologian laitos. Jyväskylän yliopisto. Jänteiden tehtävänä on kiinnittää lihakset luihin ja kuljettaa lihasten synnyttämät voimat luihin. Koska jänteiden solut käyttävät happea ja sisältävät energia-aineenvaihduntajärjestelmän entsyymiketjuja, niiden uskotaan käyttävän glukoosia energia-aineenvaihdunnassaan. Positroniemissiotomografia (PET) on radioaktiivisia isotooppeja hyödyntävä kuvantamismenetelmä, jolla voidaan tutkia elimistön biokemiallisiaja aineenvaihdunnallisia tapahtumia in vivo. Tämän tutkimuksen …
