Arterial Stiffness and Its Relationship to Cardiorespiratory Fitness in Children and Young Adults with a Fontan Circulation

2019

There are no previous studies on arterial stiffness and its associations with cardiorespiratory fitness in young Fontan patients. Therefore, we examined the arterial stiffness and its relationship to cardiorespiratory fitness in children and young adults with a Fontan circulation. Altogether, 17 Fontan patients and 26 healthy controls (16 females and 27 males aged 8–40 years) participated in this cross-sectional study. The cardiorespiratory fitness was assessed by cardiopulmonary exercise testing on a cycle ergometer and was defined as the standard deviation scores (SDS) of peak oxygen uptake per body mass (VO2peak/kg) based on the national reference values and assessed with cardiopulmonary…

Early adolescent aggression predicts antisocial personality disorder in young adults : a population-based study

2018

Modestly prevalent in the general population (~ 4%), but highly prevalent in prison populations (> 40%), the diagnosis of antisocial personality disorder (ASPD) involves aggression as one of several possible criteria. Using multiple informants, we aimed to determine if general aggression, as well as direct and indirect subtypes, assessed in early adolescence (ages 12, 14) predict young adulthood ASPD in a population-based sample. Using data from a Finnish population-based longitudinal twin cohort study with psychiatric interviews available at age 22 (N = 1347), we obtained DSM-IV-based ASPD diagnoses. Aggression measures from ages 12 (parental and teacher ratings) and 14 (teacher, self, and…

Maturation changes the excitability and effective connectivity of the frontal lobe : A developmental TMS-EEG study

2019

The combination of transcranial magnetic stimulation with simultaneous electroencephalography (TMS–EEG) offers direct neurophysiological insight into excitability and connectivity within neural circuits. However, there have been few developmental TMS–EEG studies to date, and they all have focused on primary motor cortex stimulation. In the present study, we used navigated high‐density TMS–EEG to investigate the maturation of the superior frontal cortex (dorsal premotor cortex [PMd]), which is involved in a broad range of motor and cognitive functions known to develop with age. We demonstrated that reactivity to frontal cortex TMS decreases with development. We also showed that although fron…

Coaches' reflections on the meaning and value of Masters athletics

2019

Masters sport is a growing social movement offering the opportunity to participate in competitive sports in later life. Although many studies have explored Masters athletes' experiences, little is known about how other actors in the sport subcultures construct meaning in Masters sport and whether their stories work to support or hinder participation. Our study explored the cultural narrative resources and life scripts surrounding sport and ageing that coaches draw upon in two European countries, England and Finland, where sport policy has put different emphasis on elite sport and sport for all. We analysed interviews from 23 athletics (track and field) coaches (8 women) to understand how th…

Online measurement of floc size, viscosity, and consistency of cellulose microfibril suspensions with optical coherence tomography

2021

AbstractIn this study, cellulose microfibril (CMF) suspensions were imaged during pipe flow at consistencies of 0.4%, 1.0%, and 1.6% with optical coherence tomography (OCT) to obtain images of the structure and the local velocity of the suspension. The viscosities obtained by combining pressure loss measurement with the OCT velocity data showed typical shear thinning behavior and were in excellent agreement with viscosities obtained with ultrasound velocity profiling. The structural OCT images were used to calculate the radial and the axial floc sizes of the suspension. A fit of power law to the geometrical floc size–shear stress data gave the same power law index for all consistencies, sug…

Characterization of micro-fibrillated cellulose fiber suspension flow using multi scale velocity profile measurements

2017

Rheological properties and boundary layer flow behavior of Micro Fibrillated Cellulose (MFC) suspended in water was studied using a novel velocity profiling rheometric technique. The method is based on measuring stationary velocity profiles of fluid flow in a straight tube simultaneously by Doppler Optical Coherence Tomography (DOCT) and by Ultrasound Velocity Profiling (UVP). The high resolution DOCT provides velocity profiles near the transparent tube wall, while UVP yields corresponding information in the interior parts of the flow. The data from the two instruments is combined into a comprehensive velocity profile including both the thin boundary layer near the wall and the interior par…

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…

Aikuisuus nuorten kokemana : nuorten kokemuksia aikuisten arjesta ja mielikuvia omasta tulevaisuudesta aikuisena

2015

Jokinen, Veera. 2015. Aikuisuus nuorten kokemana. Nuorten kokemuksia aikuisten arjesta ja mielikuvia omasta tulevaisuudesta aikuisena. Kasvatustieteen pro gradu- tutkielma. Jyväskylän yliopisto. Opettajankoulutuslaitos. Tämän tutkimuksen tarkoituksena oli tutkia nuorten kokemuksellista suhdetta aikuisuuteen. Tavoitteena oli ymmärtää, miten nuoret kokevat heitä ympäröivien aikuisten arjen ja elämän, sekä millaisia tulevaisuuskuvia nuorilla on omasta aikuisuudestaan. Tutkimuksen tavoitteena oli lisätä ymmärrystä nuorten kokemuksista ohjauksen kehittämiseksi. Tutkimus toteutettiin aineistolähtöisesti fenomenologisen metodin ohjaamana. Kohdejoukkona toimivat 9.-luokkalaiset nuoret. Aineisto ker…

The usage of social media among young adults living in Nairobi, Kenya : only entertainment or contributions to societal change?

2015

Social media usage has been found to have increased all over the world, also in the so-called developing countries. Although the percentages are still rather low, it can be argued that the use of social media is becoming increasingly important also in African countries. Kenya has been found to be one of the leading countries regarding social media usage in East Africa. Although research on social media has been conducted, for instance, on the use of social media in protest movements and in the areas of users’ motivation, less emphasis has been placed on their developmental aspects. Thus, to gain a deeper understanding of the usage of social media in the so-called developing countries, this …
