Predictors of In‐School and Out‐of‐School Sport Injury Prevention : A Test of The Trans‐Contextual Model

2021

The current study aimed to predict secondary school students' motivation toward sport injury prevention in 'in-school' and 'out-of-school' contexts, and their sport injury prevention behaviour at 3-month follow-up using the trans-contextual model (TCM). Hong Kong secondary school students (N = 1,566; mean age = 13.34 years, range = 11 to 19; female = 49.42%) were recruited. Participants were asked to complete a survey comprising previously-validated scales measuring TCM constructs at baseline, and a measure of sport injury prevention behaviour at follow-up three months later. Structural equation modeling (SEM) was used to examine the hypothesised paths among TCM constructs. A SEM specifying…

Weak warning signals can persist in the absence of gene flow

2019

Aposematic organisms couple conspicuous warning signals with a secondary defense to deter predators from attacking. Novel signals of aposematic prey are expected to be selected against due to positive frequency-dependent selection. How, then, can novel phenotypes persist after they arise, and why do so many aposematic species exhibit intrapopulation signal variability? Using a polytypic poison frog (Dendrobates tinctorius), we explored the forces of selection on variable aposematic signals using 2 phenotypically distinct (white, yellow) populations. Contrary to expectations, local phenotype was not always better protected compared to novel phenotypes in either population; in the white popul…

Vegetation Patterns in the Hyperbolic Klausmeier Model with Secondary Seed Dispersal

2023

This work focuses on the dynamics of vegetation stripes in sloped semi-arid environments in the presence of secondary seed dispersal and inertial effects. To this aim, a hyperbolic generalization of the Klausmeier model that encloses the advective downhill transport of plant biomass is taken into account. Analytical investigations were performed to deduce the wave and Turing instability loci at which oscillatory and stationary vegetation patterns arise, respectively. Additional information on the possibility of predicting a null-migrating behavior was extracted with suitable approximations of the dispersion relation. Numerical simulations were also carried out to corroborate theoretical pre…

Tieto- ja viestintätekniikka eri oppijatyyppien tukena vieraan kielen opinnoissa

2013

This study focuses on how learners with different learning styles can best use and profit from the different possibilities offered by e-learning in their second language acquisition. The study also discusses the alternatives to integrate the traditional learning in the classroom with distance learning using the solutions offered by e-learning. Aspects relevant to theories on second language acquisition, e-learning and different learning styles are extensively discussed. The study is both an action research and a case study research. The data measuring the students’ learning styles and experiences of using e-learning in their second language studies were gathered at HAAGA-HELIA University of…

Minervan miehet : tieteellisen antikvariaatin kirjanvälitystoimintaa akateemisissa verkostoissa

2020

Tutkin artikkelissani henkilö- ja verkostohistoriallisesta näkökulmasta antikvaarista kirjakauppaa, jota käytiin Helsingin yliopiston opiskelijoiden ja tutkijoiden muodostamissa akateemisissa verkostoissa. Minerva Oy oli 1800- ja 1900-luvun vaihteessa Helsingissä toiminut tieteellinen antikvaarinen kirjakauppa. Tarkastelen Minerva-osakeyhtiön historiaa 1890-luvulta 1910-luvulle sen piirissä toimineiden henkilöiden kautta hyödyntämällä kollektiivibiografista menetelmää. Pohdin, miten ja miksi akateemiset henkilöverkostot edesauttoivat liikkeen kirjanvälitystoimintaa. Minervan perustajat ja keskeiset toimijat tunsivat toisensa opiskeltuaan ja työskenneltyään Helsingin yliopiston piirissä. Näi…

Effects of progressive aquatic resistance training on symptoms and quality of life in women with knee osteoarthritis: A secondary analysis.

2020

Abstract Objective: To conduct a secondary analysis to study the effects, those 4 months of aquatic resistance training have on self‐assessed symptoms and quality of life in post‐menopausal women with mild knee osteoarthritis (OA), after the intervention and after a 12‐month follow‐up period. Methods: A total of 87 post‐menopausal volunteer women, aged 60‐68 years, with mild knee OA were recruited in a randomized, controlled, 4‐month aquatic training trial (RCT) and randomly assigned to an intervention (n = 43) and a control (n = 44) group. The intervention group participated in 48 supervised aquatic resistance training sessions over 4 months while the control group maintained their usual l…

Lipid Binding Controls Dimerization of the Coat Protein p24 Transmembrane Helix

2019

Abstract Coat protein (COP) I and COP II complexes are involved in the transport of proteins between the endoplasmic reticulum and the Golgi apparatus in eukaryotic cells. The formation of COP I/II complexes at membrane surfaces is an early step in vesicle formation and is mastered by p24, a type I transmembrane protein. Oligomerization of p24 monomers was suggested to be mediated and/or stabilized via interactions within the transmembrane domain, and the p24 transmembrane helix appears to selectively bind a single sphingomyelin C18:0 molecule. Furthermore, a potential cholesterol-binding sequence has also been predicted in the p24 transmembrane domain. Thus, sphingomyelin and/or cholestero…
