Developing a metatheoretical framework for second language development : a cultural-historical theory and dynamic systems theory perspective

2017

The main aim of this article-based dissertation is to construct and articulate a dialectical metatheoretical architecture for the study of second language development termed Purposive-Historical Systems Theory (PHiST) invoking, inter alia, the axiomatic imperatives of dynamic systems theory (DST), Vygotskian cultural-historical theory (CHT), and Pepperian root metaphor theory (RMT). Specifically, it primarily purports, first, to demonstrate the tenability of a dialectical synthesis of DST and CHT; second, to philosophize on the fundamental contours of PHiST; third, to apply a novel metatheoretical perspective, as a quintessential example, to reconceptualizing the seminal construct of the Zo…

Current L2 self-concept of Finnish comprehensive school students : The role of grades, parents, peers, and society

2021

L2 (second/foreign language) motivation research in Finland has been scarce. Furthermore, international motivational research has focused more on ideal and ought-to selves, leaving the current L2 self-concept in the background. In the present study, we attempted to address this gap, exploring what shapes L1 (mother tongue) Finnish students' understanding of themselves as users and learners of L2s. Using structural equation modelling, we studied the relationships between students' (n = 1206) current L2 self-concept and parental encouragement, peer pressure, societal expectations, and grades. We further studied which of these factors are the best predictors of students' current L2 self-concep…

Motivation to learn English : a case study of a 7th grade class

2017

Motivaatiota ja sen vaikutusta kielen oppimiseen on tutkittu laajalti. Tämän tutkimuksen tarkoituksena on selvittää 7. luokkalaisten opiskelumotivaatiota, kun he ovat aloittaneet yläkoulun uudessa koulussa, uudessa luokassa ja uuden opettajan kanssa. Keskeisenä kysymyksenä on: Mikä saa 7. luokkalaisen ymmärtämään motivaation merkityksen englannin kielen opiskelussa? Tämä tutkimus keskittyy oppilaiden narratiivisiin kirjoitelmiin, jossa he tuovat esiin omia näkökulmiaan ja ajatuksiaan oppimiseen motivoivista tekijöistä sekä oppimisen motivaatiota heikentävistä tekijöistä. Tutkimus toteutettiin narratiivisten kirjoitelmien avulla tapaustutkimuksena. Tutkimukseen osallistui oppilaita vain yhde…

Dialogical view on learner agency of immigrant pupils : a case study of the learners of Finnish as L2

2022

This study explores the dialogical nature of agency when two immigrant pupils, who are learning Finnish as their new target language, are authoring their selves. Bakhtin’s dialogism was the inspiration for this examination of the discourses that surround the L2 pupils’ agency and how they respond to discourses through their agency. Ethnographically oriented data collection included classroom observations, the pupils’ portfolios, and interviews with the pupils (as main participants) and meaningful adults. These data yielded a set of narratives from multiple voices. The results show that the pupils negotiate more subjective meanings of their selves, and re-color them with their internal goals…

Using Temporal Expectation to Assess Auditory Streaming in Mice

2018

Auditory streaming is the process by which environmental sound is segregated into discrete perceptual objects. The auditory system has a remarkable capability in this regard as revealed in psychophysical experiments in humans and other primates. However, little is known about the underlying neuronal mechanisms, in part because of the lack of suitable behavioural paradigms in non-primate species. The mouse is an increasingly popular model for studying the neural mechanisms of perception and action because of the range of molecular tools enabling precise manipulation of neural circuitry. Here we present a novel behavioural task that can be used to assess perceptual aspects of auditory streami…

Clean Agent Selection Approached by Fuzzy TOPSIS Decision-Making Method

2008

Abstract. It is well known that halons are ozone-depleting substances and their release into the atmosphere has contributed in the last decades to the reduction in the ozone layer. In consequence to the Montreal Protocol, an international agreement designed to gradually eliminate the use of such substances, fire protection industry researchers faced the challenge of finding effective solutions to replace halon extinguishers. This research aims to provide a method to support the decision maker in the selection of the most suitable extinguisher substance for a specific application. According to such framework, a set of quantitative and qualitative criteria has been established in the decision…

LEAVES OFNERIUM OLEANDERL. AS BIOACCUMULATORS OF POLYCYCLIC AROMATIC HYDROCARBONS (PAH) IN THE AIR OF PALERMO (ITALY): EXTRACTION AND GC-MS ANALYSIS,…

2005

Polycyclic Aromatic Hydrocarbons (PAH) were determined in the leaves of Nerium oleander L. an evergreen plant that occurs widely in both urban and rural areas, to monitor the degree of pollution in the urban area of Palermo (Italy) compared to remote areas. Twenty sites (urban roadside, urban, urban park, suburban and rural) in and around Palermo city were investigated. The purpose of this research was to investigate concentration levels and distribution patterns and relate them to possible sources. Analysis of 19 PAH was performed by gas chromatography/mass spectrometry (GCMS) using selected ion monitoring (SIM). The total amount of PAH ranged from 10 to 166 μg/Kg d.w. Each source gives ri…
