Pedagogical practices predicting perceived learning of social skills among university students
2022
The aim of this study was to examine what kinds of pedagogical practices predict perceived learning of university students’ social skills in classes where these skills are not set as learning outcomes. Data were collected from students of various disciplines by means of a questionnaire and then analysed using regression analysis. Students’ learning of social skills was explained by pedagogical factors related to 1) the modes of teaching and learning, 2) the features of the constructivist learning environment, 3) the features of the integrative pedagogy, and 4) the circumstances pertaining to the atmosphere of the learning environments involved in their studies. Factors belonging to three of…
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 …
Inter‐individual variation of the urinary steroid profiles in Swedish and Norwegian athletes
2020
The steroidal module of the Athlete Biological Passport (ABP) aims to detect doping with endogenous steroids, e.g. testosterone (T), by longitudinally monitoring several biomarkers. These biomarkers are ratios combined of urinary concentrations of testosterone and metabolically related steroids. However, it is evident after five years of monitoring steroid passports, that there are large variations in the steroid ratios complicating its interpretation. In this study, we used over 11 000 urinary steroid profiles from Swedish and Norwegian athletes to determine both the inter‐ and intra‐individual variations of all steroids and ratios in the steroidal passport. Furthermore, we investigated if…

Uskottavuusfunktion approksimointi gaussisella variaatiomenetelmällä Poisson-sekamallin ja -latentin muuttujamallin tapauksessa
2017
Tilastollisen mallin parametrit estimoidaan usein suurimman uskottavuuden menetelmällä. Havaitulla aineistolla ja voimassa olevan mallin vallitessa suurimman uskottavuuden estimointi valitsee malliparametreille arvot, jotka maksimoivat uskottavuusfunktion. Uskottavuusfunktion ollessa integraali yli latenttien eli havaitsemattomien muuttujien, ei uskottavuusfunktiota voida kuitenkaan kirjoittaa suljetussa muodossa. Tällöin uskottavuusfunktio voidaan approksimoida variaatiomenetelmällä. Variaatiomenetelmässä uskottavuusfunktiolle lasketaan alaraja, jota maksimoimalla saadaan approksimaatiot malliparametrien suurimman uskottavuuden estimaattoreille. Variaatiomenetelmä tuottaa malliparametrien …
