Eksperttiopettajan kielikasvatuksen käyttöteoria monikielisten lasten varhaiskasvatuksessa

2021

Tässä tapaustutkimuksessa tarkastelemme, millainen käyttöteoria kaksikielistä pedagogiikkaa (suomi-ruotsi) varhaiskasvatuksessa toteuttavalla eksperttiopettajalla on eri kielten käytöstä monikielisten lasten kanssa toimiessa. Käyttöteorialla tarkoitetaan tässä pedagogista näkemystä, joka ohjaa opettajan toimintaa. Käyttöteoriaa eri kielten käytöstä lähestyttiin kahden tutkimuskysymyksen kautta, joissa tarkasteltiin kielikasvatuksen käyttöteorian keskeisiä osa-alueita ja niiden ilmenemistä eri kielissä. Aineistona oli yhden eksperttiopettajan kaksi haastattelua, jotka analysoitiin laadullisella temaattisella analyysillä. Tulokset osoittavat, että opettajan kielikasvatuksen käyttöteoriassa ko…

Multimodal Aposematic Defenses Through the Predation Sequence

2021

Aposematic organisms warn predators of their unprofitability using a combination of defenses, including visual warning signals, startling sounds, noxious odors, or aversive tastes. Using multiple lines of defense can help prey avoid predators by stimulating multiple senses and/or by acting at different stages of predation. We tested the efficacy of three lines of defense (color, smell, taste) during the predation sequence of aposematic wood tiger moths (Arctia plantaginis) using blue tit (Cyanistes caeruleus) predators. Moths with two hindwing phenotypes (genotypes: WW/Wy = white, yy = yellow) were manipulated to have defense fluid with aversive smell (methoxypyrazines), body tissues with a…

Influence of colour, smell and taste on the survival of the wood tiger moth (Arctia plantaginis) adults during predation event

2021

Saalistajien torjumiseksi saalis voi käyttää erilaisia puolustusmekanismeja, jotka stimuloivat useita eri aisteja (ts. multimodaalista signalointia). Esimerkiksi aposemaattiset eliöt puolustautuvat varoitussignaalin lisäksi sekundaarisella puolustuksella. Tässä tutkimuksessa keskityttiin siihen, kuinka täpläsiilikkään (Arctia plantaginis) väritys (genotyypit WW, Wy ovat valkoisia ja yy keltaisia), haju (metoksipyratsiinista) ja maku (pyrrolitsidiinialkaloidista) toimivat puolustuksena lintusaalistajien hyökkäyksiä vastaan. Linnuille tarjottiin kummankin värisiä eläviä siilikkäitä, joita oli manipuloitu niin, että niillä oli joko hajua, makua tai molempia näistä. Näin pystyttiin tutkimaan ku…

Assessing Transfer Entropy in cardiovascular and respiratory time series: A VARFI approach

2021

In the study of complex biomedical systems represented by multivariate stochastic processes, such as the cardiovascular and respiratory systems, an issue of great relevance is the description of the system dynamics spanning multiple temporal scales. Recently, the quantification of multiscale complexity based on linear parametric models, incorporating autoregressive coefficients and fractional integration, encompassing short term dynamics and long-range correlations, was extended to multivariate time series. Within this Vector AutoRegressive Fractionally Integrated (VARFI) framework formalized for Gaussian processes, in this work we propose to estimate the Transfer Entropy, or equivalently G…

Author Correction: Evaluation of three methods for biomass estimation in small invertebrates, using three large disparate parasite species as model o…

2018

Invertebrate biomass is considered one of the main factors driving processes in ecosystems. It can be measured directly, primarily by weighing individuals, but more often indirect estimators are used. We developed two indirect and non-destructive approaches to estimate biomass of small invertebrates in a simple manner. The first one was based on clay modelling and the second one was based on image analysis implemented with open-source software. Furthermore, we tested the accuracy of the widely used geometric approximation method (third method). We applied these three different methods to three morphologically disparate model species, an acanthocephalan worm, a crustacean and a flatworm. To …

Inferring Phytoplankton, Terrestrial Plant and Bacteria Bulk δ¹³C Values from Compound Specific Analyses of Lipids and Fatty Acids.

2015

Stable isotope mixing models in aquatic ecology require δ13C values for food web end members such as phytoplankton and bacteria, however it is rarely possible to measure these directly. Hence there is a critical need for improved methods for estimating the δ13C ratios of phytoplankton, bacteria and terrestrial detritus from within mixed seston. We determined the δ13C values of lipids, phospholipids and biomarker fatty acids and used these to calculate isotopic differences compared to the whole-cell δ13C values for eight phytoplankton classes, five bacterial taxa, and three types of terrestrial organic matter (two trees and one grass). The lipid content was higher amongst the phytoplankton (…

The Effects of General and Mobile Online Shopping Skilfulness and Multichannel Self-Efficacy on Consumer Showrooming Behaviour

2022

Although showrooming behaviour is a characteristic aspect of modern omnichannel retailing, our understanding of its antecedents remains limited. In this study, we aim to address this gap in prior research by examining how showrooming behaviour is affected by three different kinds of perceived consumer capabilities: general online shopping skilfulness, mobile online shopping skilfulness, and multichannel self-efficacy. The examination is done by utilising data from 1,024 Finnish consumers, which was collected with an online survey in 2021 and is analysed with structural equation modelling (SEM). In summary, we find mobile online shopping skilfulness to have a strong positive effect on showro…

Doing gender and sexuality intersectionally in multimodal social media practices

2021

The chapter focuses on how members in participatory cultures engage in everyday, informal, and interest-driven social and discursive practices primarily on social media but also in ways that relate to the material and physical contexts of their lives. We show how social actors operating in these sites construct gender and sexuality intersectionally and multimodally. We argue that gender and sexuality are always constructed at intersections with other identity categories. With respect to both digital and physical participatory activities, multisemioticity is, in turn, necessary as an analytic perspective: it allows the investigation of how participants routinely draw on and deploy a range of…
