Transient changes in heart rate variability in response to orthostatic task, endurance exersice and training : with special reference to autonomic bl…
2009
Heart rate variability (HRV) is generally accepted as an estimate of the autonomic, particularly vagal, control of the heart. The quantitative relationship of HRV to vagal heart rate (HR) control is, however, unclear. In addition, the conventional analysis methods of HRV are not suitable for analyzing rapid adjustments of autonomic control. Time-frequency analysis methods, including short-time Fourier transform (STFT), have been developed for analyzing non-stationary signals.The present study was designed to evaluate the ability of HRV to quantify within-subject changes in autonomic HR control by using autonomic blockades and an active orthostatic task, and to study transient changes in HRV…

TallVocabL2Fi : A Tall Dataset of 15 Finnish L2 Learners’ Vocabulary
2022
Previous work concerning measurement of second language learners has tended to focus on the knowledge of small numbers of words, often geared towards measuring vocabulary size. This paper presents a “tall” dataset containing information about a few learners’ knowledge of many words, suitable for evaluating Vocabulary Inventory Prediction (VIP) techniques, including those based on Computerised Adaptive Testing (CAT). In comparison to previous comparable datasets, the learners are from varied backgrounds, so as to reduce the risk of overfitting when used for machine learning based VIP. The dataset contains both a self-rating test and a translation test, used to derive a measure of reliability…

Tendon length estimates are influenced by tracking location
2022
Abstract Purpose Measurement of medial gastrocnemius (MG) tendon length using ultrasonography (US) requires the muscle–tendon junction (MTJ) to be located. Previously, the MG MTJ has been tracked from different proximo-distal locations near the MTJ, which could influence estimates of tendon length change due to the different characteristics of the aponeurosis and tendon. We used US to evaluate the effect of tracking point location on MG MTJ displacement during maximal and submaximal (10, 20 and 30% of the non-injured maximal) isometric plantar flexion contractions. Methods Displacement behaviour of MTJ was tracked from (1) the exact MTJ; and (2) from an insertion point of a muscle fascicle …
Methodological Guidelines Designed to Improve the Quality of Research on Cross-Country Skiing
2021
AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinet…
Face and Content Validity of the Pictorial Scale of Perceived Water Competence in Young Children
2022
An international group of experts have developed a pictorial tool to measure perceived water competence for children aged from 5 to 8 years old: the Pictorial Scale of Perceived Water Competence (PSPWC). The aim of the present study was to verify the validity of this tool. In the first part of the study, 120 children were interviewed to investigate face validity of the PSPWC to ensure that all pictorial items were understandable. In the second part of the study, 13 scientific and/or pedagogical international experts were invited to assess the tool’s content validity via an online survey. Face validity results revealed that children were able to understand and sequence correctly the aq…
Ihmisen ja teknologian välisessä vuorovaikutuksessa syntyvä käyttäjäkokemus ja sen mittaamisen haasteet
2016
Kiinnostus käyttäjäkokemusta kohtaan perinteisen käytettävyyden ohella ihmisen ja teknologian välisessä vuorovaikutuksessa on lisääntynyt vuosituhannen vaihteen jälkeen. Huolimatta kasvavasta kiinnostuksesta käyttäjäkokemusta kohtaan, yhteisymmärryksen löytäminen sen luonteesta ja laajuudesta on ollut tutkijoiden keskuudessa kuitenkin vaikeaa eikä yleisesti hyväksyttyä, kokonaisvaltaista määritelmää ole onnistuttu löytämään. Selkeä määritelmä tarjoaisi kuitenkin monia hyötyjä. Se esimerkiksi selkeyttäsi ja edistäisi käyttäjäkokemuksen tutkimusta tutkijoiden ja ammatinharjoittajien keskuudessa, sekä tarjoaisi vankan pohjan käytännön työlle käyttäjäkokemuksen parissa. Tässä kirjallisuuskatsau…
