Inlärning av sverigesvenska vokaler hos universitetsstudenter med finska som S1
2015
Tämän pro gradu -tutkielman tarkoituksena oli selvittää, kehittyikö yliopistossa ruotsia opiskelevien ruotsinruotsalainen vokaaliääntämys kuuden viikon mittaisen ääntämiskurssin aikana. Tutkimukseen osallistui kuusi ruotsinopiskelijaa sekä verrokkiryhmä, neljä syntyperäistä ruotsalaista. Tutkimusaineisto koostui ruotsinkielisistä lauseista, jotka luettiin nauhalle kielistudiossa kurssin alussa ja lopussa. Lisäksi kurssin alussa luettiin nauhalle suomenkielisiä lauseita vokaalien vertailua varten. Aineisto analysointiin akustisesti auditiivisia havaintoja tukena käyttäen. Analyysi rajattiin koskemaan vokaaliäänteitä [ɑ:], [i:], [y:] ja [ʉ:], koska niiden voi aiempaan tutkimukseen perustuen o…
Behaviour of Extractives in Norway Spruce (Picea abies) Bark during Pile Storage
2022
The current practices regarding the procurement chain of forest industry sidestreams, such as conifer bark, do not always lead to optimal conditions for preserving individual chemical compounds. This study investigates the standard way of storing bark in large piles in an open area. We mainly focus on the degradation of the most essential hydrophilic and hydrophobic extractives and carbohydrates. First, two large 450 m3 piles of bark from Norway spruce (Picea abies) were formed, one of which was covered with snow. The degradation of the bark extractives was monitored for 24 weeks. Samples were taken from the middle, side and top of the pile. Each sample was extracted at 120 °C with both n-h…
Physical Performance During the Menopausal Transition and the Role of Physical Activity
2020
Abstract Background To examine longitudinal changes in physical performance during the menopausal transition and the role of physical activity (PA) in these changes. Methods Based on follicle-stimulating hormone levels and bleeding diaries, women (47–55 years) were classified as early (n = 89) and late perimenopausal (n = 143) and followed prospectively until postmenopausal status, with mean duration of 17.5 and 13.8 months, respectively. Physical performance was measured by handgrip force, knee extension torque, vertical jumping height, maximal walking speed, and 6-minute walking distance. Physical activity was self-reported and categorized as inactive, low, medium, and high. Longitudinal …
Ēšanas traucējumu saistība ar kaunu, vainu un perfekcionismu jauniešiem
2022
Pētījuma mērķis ir izpētīt saistības starp attieksmi pret ēšanu, kaunu, vainu un perfekcionismu jauniešiem. Pētījumā piedalījās 73 respondenti vecuma diapazonā no 15-25 gadiem. Pētījumā tika izmantotas – Attieksmes pret ēšanu aptauja” (The Eating Attitudes Tests [EAT-26], Garner, Olmsted, Bohr, & Garfinkel, 1982), „Hroniskā kauna un vainas aptauja” (Ķirsis J., Raščevska M., 2014) un „Perfekcionisma aptauja” (Almost Perfect Scale – Revised Short Form, Slaney, Rice, Mobley, Trippi, & Ashby, 2001). Iegūtie rezultāti uzrādīja statistiski nozīmīgas saistības starp ēšanas traucējumiem un kauna, vainas un perfekcionisma rādītājiem. Augstāki kauna, vainas un perfekcionisma rādītāji ir saistīti ar a…
Comparison of inter-trial recovery times for the determination of critical power and W' in cycling
2017
Critical Power (CP) and W’ are often determined using multi-day testing protocols. To investigate this cumbersome testing method, the purpose of this study was to compare the differences between the conventional use of a 24-h inter-trial recovery time with those of 3 h and 30 min for the determination of CP and W’. Methods: 9 moderately trained cyclists performed an incremental test to exhaustion to establish the power output associated with the maximum oxygen uptake (p V O2max), and 3 protocols requiring time-to-exhaustion trials at a constant work-rate performed at 80%, 100% and 105% of p VO2max. Design: Protocol A utilised 24-h inter-trial recovery (CP24/W’24), protocol B utilised 3-h in…
A New Reliable Performance Analysis Template for Quantifying Action Variables in Elite Men’s Wheelchair Basketball
2019
This study aimed to develop a valid and reliable performance analysis template for quantifying team action variables in elite men’s wheelchair basketball. First action variables and operational definitions were identified by the authors and verified by an expert panel of wheelchair basketball coaching staff in order to establish expert validity. A total of 109 action variable were then placed into 17 agreed Categorical Predictor Variable categories. The action variables were then used to develop a computerized performance analysis template for post-event analysis. Each possession (n = 200) from an international men’s wheelchair basketball game was analyzed by the first author on two occasio…
El dolor crónico en las personas adultas con osteogénesis imperfecta y su relación con la personalidad, valoración, afrontamiento y calidad de vida: …
2022
La osteogénesis imperfecta (OI), popularmente conocida como la “enfermedad de los huesos de cristal”, es una patología congénita del tejido conectivo, de carácter hereditario, que afecta principalmente a la producción de colágeno. Presenta una etiología y clínica muy heterogénea, con amplia variedad fenotípica, aunque su principal característica es la elevada fragilidad ósea, que se traduce en fracturas frecuentes. Otras manifestaciones clínicas habituales en la patología son las escleras azuladas, dentinogénesis imperfecta, hiperlaxitud de ligamentos y piel, problemas de audición y visión y deformidades óseas. Su incidencia es de 1/15.000 a 1/ 20.000 recién nacidos, por lo que se considera…
Audit Measurement of Crisis Communication Preparedness across Different Branches of Government : Sharing Experiences Gained in Finland
2018
An audit measurement of crisis communication preparedness was conducted for 67 organizations, mainly on the national level, in Finland. This unique project was one of the ways to implement new crisis communication regulations getting into force a year earlier. Its purpose was to strengthen central government communication in incidents and emergencies. The audit consisted of a digital survey in the participating organizations and a reflection meeting on the level of each of the 14 branches involved. The indicators were customized taking the crisis communication scorecard, developed in an international project, as a basis. In addition, several meetings were arranged to facilitate related inte…
Patterns of Children’s Relationships With Parents and Teachers in Grade 1 : Links to Task Persistence and Performance
2022
Our study aimed to investigate the patterns of children’s relationships with their parents and teachers, the development of these relationships during Grade 1, and respective links to children’s learning (in task persistence and performance). Parents of 350 children answered questionnaires about the quality of their relationships with their children; 25 teachers answered questions about children’s task persistence at school and the quality of their relationships with their students; 350 children completed literacy and math performance tests; and six testers evaluated children’s task persistence when completing those tests. All measures were administered twice: at the start and end of Grade …
The roles of achievement-related behaviours and parental beliefs in children´s mathematical performance
2003
This study aimed to investigate the developmental dynamics between children's mathematical performance, the task-focused versus task-avoidant behaviours they show in the classroom, and their parents' beliefs concerning their school competence. The mathematical performance of 111 six- to seven-year-old children was tested, and their task-focused versus task-avoidant behaviours were rated by their teachers four times during their first school year. Parents filled in questionnaires measuring their skill-specific and general beliefs about their children's school competencies at the beginning and at the end of the school year. The results showed that parents' beliefs in their children's general …
