Alkuvaiheen S2-oppijoiden käsityksiä puheen ymmärtämisen vaikeuksista ja kompensaatiostrategioista

2015

This article examines adult L2 Finnish learners’ perceptions of listening difficulties and compensatory strategies in everyday situations. The data consist of questionnaire answers (N = 202) and five semi-structured interviews. The answers were grouped according to the reasons why listening difficulties were experienced. The number of times each reason was mentioned was calculated in order to find out to what extent the reasons were shared by the group. The interviews were used as a complementary resource for analysing the questionnaire answers. The results suggest that listening difficulties were most commonly attributed to speech rate, colloquial language and unfamiliar words, and it is a…

Effects of training background to acute psychological stress biomarkers

2016

Stressi on laajalti tutkittu aihe ja kroonisen stressin aiheuttamat terveysvaikutukset ovat merkittäviä maailmassa. Stressi käsitteenä voidaan ajatella tarkoittavan tilannetta, jolloin homeostaasia järkytetään. Stressi voidaan jakaa henkiseen ja fyysiseen sekä pitkäaikaiseen ja lyhytkestoiseen. Ihmisen kokiessa stressiä, niin henkistä tai fyysistä, tapahtuu hermoston toiminnan johdosta erilaisia fysiologisia muutoksia ihmiskehossa. Reaktio stressiin johtaa esimerkiksi sykkeen kiihtymiseen, verenpaineen kohoamiseen sekä erilaisten hormonien erittymiseen, kuten: adrenaliini ja kortisoli. Tässä tutkimuksessa on tarkoituksena tutkia miten erilaisen harjoitustaustan omaavien henkilöiden fysiolog…

Voimaharjoittelun vaikutukset dynaamiseen ja staattiseen tasapainoon nuorilla ja ikääntyneillä

2017

Tasapainolle ei ole olemassa universaalia määritelmää mutta se tiedetään, että sitä kontrolloivat useat eri mekanismit. Ikääntyminen aiheuttaa siinä heikkenemistä, joka aiheutuu muutoksista sekä sensorisissa että motorisissa prosesseissa. Kaatumisesta aiheutuneiden vammojen määrä kasvaa koko ajan ikääntyneillä. Heidän onkin havaittu pärjäävän nuoria huonommin sekä staattisissa että dynaamisissa testeissä mutta dynaamisissa testeissä ero on vieläkin suurempi. Erityisesti dynaamisten ominaisuuksin tutkiminen on tärkeää sillä staattiset testit eivät välttämättä paljasta tasapaino-ongelmia tai ikääntymiseen liittyviä eroja yhtä hyvin kuin dynaamiset testit. Tämän tutkimuksen suoritti loppuun 4 …

What contexts are favorable for the adoption of the contract teacher policy ?

2010

Education systems in Francophone African countries are undergoing major reforms, consequence of the international commitment to achieve Universal Primary Education (UPE) by 2015. Teachers' recruitment is among the most important reforms for at least two reasons: first, various researches presented it as necessary otherwise UPE will not be achieved; second, the alternative policy proposed is unpopular as new teachers are recruited with lower qualification, receive lower salaries and have a less secure job position. Yet, some governments have succeeded in changing their teacher recruitment scheme and others have not. Conditions allowing a government to make the reform are still uninvestigated…

Enabling and constraining family: young women building their educational paths in Tanzania

2015

For an increasing number of African girls and women, upgrading the level of education has become a strategy for life improvement. This paper analyses the role that family plays in enabling women's education and contributes to understanding on the interconnectivity of education, work and family in women's lives in collective societies. The analysis focuses on how young Tanzanian women perceive the role of family and education in their ‘youth task’, of becoming adult. The analysis is based on interviews with seven young Tanzanian women enrolled in non-formal secondary education and nine professional women enrolled in higher education. The results show that the women were determined to pursue …

Official Development Assistance in fragile states: an unresolved issue - Focus on education

2013

Since the mid 2000s, the theme of "fragile states" became a structuring axis of development policies of most donors. Insofar as investment in education is perceived as a necessary, if not sufficient, to vanquish poverty, the option to stimulate and accelerate the development of education constitutes an opportunity for the international community. Even if it means that the latter also has to exercise some forms of interference. The findings of our empirical analysis show, that within fragile states, the emergence of a current contradiction between the inclusive nature of the EFA goals and the exclusionary nature of the paradigms on which foreign aid is based (effectiveness and results). This…

International aid on education in fragile states and armed conflict: what prospects?

2013

Currently, over a third of children not in school live in countries considered being as fragile or affected by an armed conflict. These countries, which are mainly located in sub-Saharan Africa, will not reach the objectives of Education For All for 2015. This paper covers approaches across comparative education, political science and sociology of organizations. The question is: what prospects for international assistance on education in fragile states and countries affected by armed conflict? Our study explores empirically the conditions of intervention of international aid within the contexts of fragility and armed conflict. Insofar as investment in education is perceived as a necessary, …
