The Eurasian Treecreeper (Certhia familiaris) has an effective camouflage against mammalian but not avian vision in boreal forests
2022
A well-known example of visual camouflage in birds is the plumage coloration of the Eurasian Treecreeper Certhia familiaris, yet this species’ camouflage has never been objectively quantified. Here, we quantify treecreeper camouflage in its boreal forest habitat, test whether treecreepers better match tree backgrounds at nest site, territory or habitat spatial scales, and explore which common tree species provide the best background match. Using photographic data of the birds and forested backgrounds, we test their background match using human, ferret and avian vision modelling. We found that a treecreeper’s wing and mantle provided closest background matching, whereas the wing stripe and t…
English and Finnish compared - attitudes held by future experts and teachers of English
2010
Kieliasenteita on tutkittu maailmalla 1960-luvulta lähtien. Tutkimusmetodit koskien kieliasenteita ovat pysyneet suhteellisen samoina siitä lähtien kun Matched guise tekniikka kehittyi. Tästä lähtien tutkimusmetodologia keskittyi erilaisiin asteikkoihin ja ennalta määrättyihin vastausvaihtoehtoihin. Näitä tutkimusmenetelmiä on kritisoitu sekä kaavamaisuudesta että vastaajien huomiotta jättämisestä. Tämän tutkielman on tarkoitus määrittää suomalaisten englannin yliopisto-opiskelijoiden asenteita englannin kieltä kohtaan. Tutkielman toinen päätarkoitus on osoittaa vaihtoehtoisten tutkimusmenetelmien tarpeellisuus kieliasenteiden tutkimuksessa. Lähtökohtana tutkimuksessa on vastaajien todellis…
Physical qualities and body composition predictors of running performance in national level women’s official soccer matches
2023
The purpose of the study was to (1) determine match running performance, anthropometry and various physical qualities of national level women soccer players and (2) identify key physical qualities and anthropometric predictors of match running profile during a competitive season. Twenty-five national level Finnish soccer players participated in the study. Players performed countermovement jump, loaded squat jumps, 30-meter sprint, maximum isokinetic knee flexor and extensor contractions, an incremental treadmill test and underwent body composition assessment in the lab. Match running performance was analyzed from 115 match observations during competitive league matches over 11 weeks after t…
Physical performance of Finnish futsal players, analysis of game intensity and fatigue in official futsal games
2017
Introduction. Futsal has grown notably in last years and have over 12 million players worldwide. Futsal is a high-intensity indoor sport where burst of multi-planar movements varies with short periods of rest. Futsal is played on a court sized 40 x 20 m for two halves of 20 min, where clock is stopped when ball is out of play. Purpose of this study was to find out physical performance of Finnish futsal players and analyse intensity and fatigue in official futsal games. Methods. Two Finnish Futsal League teams were involved (n = 19), age 26.3 (± 3.0 years), body mass 76.4 (± 6.2 kg), height 178.7 (± 5.7 cm), BMI 23.9 (± 1.4 kg/m2) and body fat % 12.3 (± 4.0 %). Measurement were done in the m…
Functional inequalities for generalized inverse trigonometric and hyperbolic functions
2014
Various miscellaneous functional inequalities are deduced for the so-called generalized inverse trigonometric and hyperbolic functions. For instance, functional inequalities for sums, difference and quotient of generalized inverse trigonometric and hyperbolic functions are given, as well as some Gr\"unbaum inequalities with the aid of the classical Bernoulli inequality. Moreover, by means of certain already derived bounds, bilateral bounding inequalities are obtained for the generalized hypergeometric ${}_3F_2$ Clausen function.
Context-aware data caching for 5G heterogeneous small cells networks
2016
In this work, we investigate the problem of context-aware data caching in the heterogeneous small cell networks (HSCNs) to provide satisfactory to the end-users in reducing the service latency. In particular, we explore the storage capability of base stations (BSs) in HSCNs and propose a data caching model consists of edge caching elements (CAEs), small cell base stations (SBSs), and macro cell BS (MBS). Then, we concentrate on how to efficiently match the data contents to the different cache entities in order to minimize the overall system service latency. We model it as a distributed college admission (CA) stable matching problem and tackle this issue by utilizing contextual information t…
A Cluster Analysis Approach to Profile Men and Women’s Volley Positions in Professional Tennis Matches (Doubles)
2021
(1) Background: Tennis ball tracking technology allows the aquirement of novel and reliable data about several performance indicators, such as volley positions. This information is key to understand match dynamics in doubles tennis and to better help preparing players for the demands they will face in match play. As such, the purpose of this study was to describe and compare the different types of volley positions in men’s and women’s doubles professional tennis. (2) Methods: Ball tracking data were collected for 46 women (Billie Jean King Cup) and 96 men’s doubles matches (Davis Cup). The variables used were the distance to the net, the distance to the centre of the court and the height of…

Ikääntymisen vaikutus visuaaliseen prosessointiin
2012
Tämän pro gradu -tutkielman tarkoituksena oli selvittää aivojen automaattisen muutoksen havaitsemisjärjestelmän toimintaa visuaalisessa järjestelmässä tapahtumasidonnaisten herätevasteiden (ERP) avulla. Lisäksi tutkielmassa haluttiin selvittää ikääntymisen mahdollisia vaikutuksia tämän järjestelmän toimintaan vertailemalla toisiinsa terveiden nuorten aikuisten (n=19, 22-27 vuotta) ja ikääntyneiden (n=10, 69-95 vuotta) visuaalisia herätevasteita N2- ja P3 -komponenteissa. Visuaalinen herätevaste, jota tutkielmassa tarkasteltiin, oli poikkeavuusnegatiivisuus (mismatch negativity, MMN). Tutkielmassa ERP:t rekisteröitiin elektroenkefalografialla (EEG) ja passiivisen oddball -paradigman avulla. …
Influence of the learning environment on the representational strategies of middle school music students: an intervention-based study
2015
The purpose of this study was to examine the effects of a hypermedia learning environment on middle school students' meta-representational competence (MRC) in the domain of music. Particularly, we aimed at determining whether an educational intervention influenced the accuracy with which middle school students matched sounds (sonic fragments) to symbols (graphic representations). The students were randomly allocated to the experimental condition. An intervention was set up so that the experimental group students (E) were provided with scaffolding aimed at enhancing their use of constructive resources to generate representations and their critical capabilities to judge them. On the other han…
