Implementation of educational change in Finland: The case of the undivided basic education reform

For the past decades, educational large-scale reforms have been elaborated and implemented in many countries and often resulted in partial or complete failure. These results brought researchers to study policy processes in order to address this particular challenge. Studies on implementation processes brought to light an existing causal relationship between the implementation process and the effectiveness of a reform. This study aims to describe the implementation process of educational change in Finland, who produced efficient educational reforms over the last 50 years. The case study used for the purpose of this study is the national reform of undivided basic education (yhtenäinen peruskoulu) implemented in the end of the 1990s. Therefore, this research aims to describe how the Finnish undivided basic education reform was implemented. This research was carried out using a pluralist and structuralist approach of policy process and was analyzed according to the hybrid model of implementation process. The data were collected using a triangulation of methods, i.e. documentary research, interviews and questionnaires. The data were qualitative and were analyzed using content analysis methods. This study concludes that the undivided basic education reform was applied in a very decentralized manner, which is a reflection of the decentralized system present in Finland. Central authorities provided a clear vision of the purpose of the reform, but did not control the implementation process. They rather provided extensive support in the form of transmission of information and development of collaborative networks. Local authorities had complete autonomy in terms of decision-making and implementation process. Discussions, debates and decisions regarding implementation processes took place at the local level and included the participation of all actors present on the field. Implementation methods differ from a region to another, with is the consequence of the variation of the level of commitment of local actors but also the diversity of local realities. The reform was implemented according to existing structures and values, which means that it was in cohesion with the context in which it was implemented. These results cannot be generalized to all implementation processes of educational change in Finland but give a great insight of what could be the model used in Finland. Future studies could intent to confirm the model described here by studying other reforms that took place in Finland.

Suomalainen yrityshautomo-konsepti Pietarissa pienen ICT-yrityksen näkökulmasta: tapaustutkimus

Tämän Pro -gradu tutkielman tavoitteena on tutkia suomalaisen yrityshautomo-konseptin soveltuvuutta venäläisten ICT-alan start-up-yrittäjien tarpeisiin. Tutkielma on tehty suomalaiselle pörssiyhtiölle, joka laajentaa toimintaansa Venäjälle perustamalla teknologiakeskuksen Pietariin. Kohdeyritys on teettänyt useita selvi-tyksiä Pietarin ICT-sektorista, sen ongelmista ja kehitystarpeista. Sen sijaan käsitystä ei ole siitä, miten haastavaksi yksittäinen yrittäjä kokee liiketoiminta-ympäristön ja mitä tukipalveluita hän liiketoiminnassaan tarvitsee. Tutkimuksen tavoitteena on vastata näihin kysymyksiin sekä peilata saatuja vastauksia kohdeyrityksen Suomessa tarjoamiin hautomopalveluihin. Kirjallisuuskatsauksessa on käyty läpi yrityshautomotoiminnan historiaa ja toiminnan saamia erilaisia muotoja. Lisäksi on perehdytty tutkimuksiin hautomotoimin-nan vaikuttavuudesta ja kriittisistä menestystekijöistä. Tutkimus on lähestymistavaltaan laadullinen case-tutkimus. Käytännössä työ to-teutettiin kyselytutkimuksena haastattelemalla kymmentä pietarilaista, pienen ICT-alan yrityksen johtajaa. Haastatteluiden perusteella kohdeyrityksen hautomokonseptia ei ole mahdollista siirtää suoraviivaisesti venäläiseen toimintaympäristöön. Kulttuurierot maiden välillä ovat merkittävät, eikä niitä ole lyhyellä tai keskipitkällä aikavälillä mahdollista poistaa. Etenkin yleinen luottamuksen puute vaikeuttaa konseptin implementointia. Alkavien ICT-yritysten haasteet ovat pitkälti samoja rajan kummallakin puolen. Rahoituksen puute ja ongelmat myynti- ja markkinointiosaamisessa tulivat haas-tatteluissa vahvasti esille. Liiketoimintaosaamisessa on paljon parannettavaa. Ensimmäisiä toteutettavaksi suositeltuja palveluita ovat siten yrittäjävalmennus ja myynnin ja markkinoinnin työpaja. Lopuksi voi todeta, että useille kohdeyrityksen tarjoamille yksittäisille palveluille on selkeä tarve. Siihen, mitä käytännössä on mahdollista ja/tai kannattavaa toteuttaa, ei oteta tässä tutkimuksessa kantaa.

Energy Efficiency in Electrical Drive Systems: Technical potentials, barriers and policy approaches for small and medium industries in Ghana

Today industries and commerce in Ghana are facing enormous energy challenge. The pressure is on for industries to reduce energy consumption, lower carbon emissions and provide se-cured power supply. Industrial electric motor energy efficiency improvement is one of the most important tools to reduce global warming threat and reduce electricity bills. In order to develop a strategic industrial energy efficiency policy, it is therefore necessary to study the barriers that inhibit the implementation of cost – effective energy efficiency measures and the driving forces that promote the implementation. The aim of this thesis is to analyse the energy consumption pattern of electric motors, study factors that promote or inhibit energy efficiency improvements in EMDS and provide cost – effective solutions that improve energy efficiency to bridge the existing energy efficiency gap in the surveyed industries. The results from this thesis has revealed that, the existence of low energy efficiency in motor-driven systems in the surveyed industries were due to poor maintenance practices, absence of standards, power quality issues, lack of access to capital and limited awareness to the im-portance of energy efficiency improvements in EMDS. However, based on the results pre-sented in this thesis, a policy approach towards industrial SMEs should primarily include dis-counted or free energy audit in providing the industries with the necessary information on potential energy efficiency measures, practice best motor management programmes and estab-lish a minimum energy performance standard (MEPS) for motors imported into the country. The thesis has also shown that education and capacity development programmes, financial incentives and system optimization are effective means to promote energy efficiency in elec-tric motor – driven systems in industrial SMEs in Ghana

Alicaligenes faecalis : identification and study of its antagonistic properties against Botrytis cinerea

A Gram negative aerobic flagellated bacterium with fungal growth inhibitory properties was isolated from a culture of Trichoderma harzianum. According to its cultural characteristics and biochemical properties it was identified as a strain of Alcaligenes (aeca/is Castellani and Chalmers. Antisera prepared in Balbc mice injected with live and heat-killed bacterial cells gave strong reactions with the homologous immunogen and with ATCC 15554, the type strain of A. taeca/is, but not with Escherichia coli or Enterobacter aerogens in immunoprecipitation and dot immunobinding assays. Growth of Botrytis cinerea Pers. and several other fungi was significantly affected when co-cultured with A. taeca/is on solid media. Its detrimental effect on germination and growth of B. cinerea has been found to be associated with antifungal substances produced by the bacterium and released into the growth medium. A biotest for the antibiotic substances, based on their inhibitory effect on germination of B. cinerea conidia, was developed. This biotest was used to study the properties of these substances, the conditions in which they are produced, and to monitor the steps of their separation during extraction procedures. It has been found that at least two substances could be involved in the antagonistic interaction. One of these is a basic volatile substance and has been identified as ammonia. The other substance is a nonvolatile, dialysable, heat stable, polar compound released into the growth medium. After separation of growth medium samples by Sephadex G-10 column chromatography a single peak with a molecular weight below 700 Daltons exhibited inhibitory activity. From its behaviour in electrophoretic separation in agarose gels it seems that this is a neutral or slightly positively charged.

The interpretation of music videos : an interactive relationship between medium and viewer

There is a great deal of evidence to support the examination of an interactive relationship between the medium and the viewer in the interpretation of mainstream media. The exact nature of this relationship, however, is not well understood. The current study was carried out to assess the variables that may help explain why certain people interpret media, such as music videos, differently than others. Jensen's concept of reception analysis describes the relationship between the medium and the audience, and thus remains a strong focus within this study. Differences in the interpretation of music videos were investigated as a function of Absorption, gender role, screen size, age and viewing experience. Multiple regression analyses uncovered independent predictions of sexuality and violence scores by absorption and experience, as well as an interaction between absorption and screen size in the sexuality rating of the music videos.

The effects of plants(Typha Latifolia)and root-bed medium on the treatment of domestic sewage within a vertical flow constructed wetland /

The effect that plants {Typha latifolia) as well as root-bed medium physical and chemical characteristics have on the treatment of primary treated domestic wastewater within a vertical flow constructed wetland system was investigated. Five sets of cells, with two cells in each set, were used. Each cell was made of concrete and measured 1 .0 m X 1 .0 m and was 1.3 m deep. Four different root-bed media were tested : Queenston Shale, Fonthill Sand, Niagara Shale and a Michigan Sand. Four of the sets contained plants and a single type of root-bed medium. The influence of plants was tested by operating a Queenston Shale set without plants. Due to budget constraints no replicates were constructed. All of the sets were operated independently and identically for twenty-eight months. Twelve months of data are presented here, collected after 16 months of continuous operation. Root-bed medium type did not influence BOD5 removal. All of the sets consistently met Ontario Ministry of Environment (MOE) requirements (<25 mg/L) for BOD5 throughout the year. The 12 month average BOD5 concentration from all sets with plants was below 2.36 mg/L. All of the sets were within MOE discharge requirements (< 25 mg/L) for suspended solids with set effluent concentrations ranging from 1.53 to 14.80 mg/L. The Queenston Shale and Fonthill Sand media removed the most suspended solids while the Niagara Shale set produced suspended solids. The set containing Fonthill Sand was the only series to meet MOE discharge requirements (< Img/L) for total phosphorus year-round with a twelve month mean effluent concentration of 0.23 mg/L. Year-round all of the root-bed media were well below MOE discharge requirements (< 20mg/L in winter and < 10 mg/L in sumnner) for ammonium. The Queenston Shale and Fonthill Sand sets removed the most total nitrogen. Plants had no effect on total nitrogen removal, but did influence how nitrogen was cycled within the system. Plants increased the removal of suspended solids by 14%, BOD5 by 10% and total phosphorus by 22%. Plants also increased the amount of dissolved oxygen that entered the system. During the plant growing season removal of total phosphorus was better in all sets with plants regardless of media type. The sets containing Queenston Shale and Fonthill Sand media achieved the best results and plants in the Queenston Shale set increased treatment efficiency for every parameter except nitrogen. Vertical flow wetland sewage treatment systems can be designed and built to consistently meet MOE discharge requirements year-round for BOD5, suspended solids, total phosphorus and ammonium. This system Is generally superior to the free water systems and sub-surface horizontal flow systems in cold climate situations.

Health-Enhancing Physical Activity and Well-Being: Is it How Often, How Long, or How Much Effort that Matters? A Test of Basic Psychological Needs Theory

The primary objectives of the present study were 1) to examine the relationship between health-enhancing physical activity (HEPA) and well-being across the previous day and 2) to examine the role of basic psychological need satisfaction as a potential mediator of the HEPA – well-being relationship. Participants (N = 203) were a convenience sample of undergraduate students with data collected cross sectionally. HEPA was generally associated with well-being (r‟s ranged from .18 to .62). Multiple mediation analyses supported psychological need satisfaction as mechanisms underpinning the HEPA – well- being relationship. Subsequent analyses demonstrated that effort put forth in HEPA activities, as opposed to frequency or duration, uniquely predicted well-being. The role of effort was further highlighted in the multiple mediation analyses. As such future research may wish to investigate the utility of a HEPA program that facilitates effortful engagement and fulfillment of basic psychological needs.

Basic Psychological Needs as mediators: An examination of the relationship between exercise and well-being

Grounded in Basic Psychological Needs Theory (Deci & Ryan, 2002), the present investigation examined whether psychological need satisfaction mediated the relationship between moderate-to-vigorous physical activity (MVPA) and well-being. Adopting a longitudinal design participants (N= 147) completed questionnaires assessing MVPA, well-being and perceived psychological need satisfaction in exercise contexts on three occasions separated by three weeks. A pattern of small-to-moderate correlations were noted between MVPA and indices of well-being (r12's ranged from .16 to .29). Multiple mediation analysis indicated that perceived psychological need satisfaction mediated the relationship between MVPA and well-being with perceived competence emerging as a unique mediator. Serial mediation analyses indicated the importance of ongoing psychological need satisfaction to well-being. Contexts that afford individuals the opportunity to engage in MVPA, as well as supports their need for competence, would be most advantageous for the promotion of psychological well-being.

Explaining the Great Divergence: Medium and Message on the Eurasian Land Mass, 1700-1850

Between 1700 and 1850, per-capita income doubled in Europe while falling in the rest of Eurasia. Neither geography nor economic institutions can explain this sudden divergence. Here the consequences of differences in communications technology are examined. For the first time, there appeared in Europe a combination of a standardized medium (national vernaculars with a phonetic alphabet) and a non-standardized message (competing religious, political and scientific ideas). The result was an unprecedented fall in the cost of combining ideas and burst of productivity-raising innovation. Elsewhere, decreasing standardization of the medium and increasing standardization of the message blocked innovation.

Fonction de l'AmtB dans la régulation de la nitrogénase chez Rhodobacter capsulatus

La fixation de l’azote diatomique est un processus très important à la vie, vu sa nécessité dans la biosynthèse de plusieurs molécules de base; acides aminés, acides nucléiques, etc. La réduction de l’azote en ammoniaque est catalysée par la nitrogénase, une enzyme consommatrice de beaucoup d’énergie étant donné qu’elle nécessite 20 à 30 moles d’ATP pour la réduction d’une mole d’azote. De ce fait une régulation rigoureuse est exigée afin de minimiser le gaspillage d’énergie. Plusieurs systèmes de contrôle sont connus, aussi bien au niveau post-traductionnel que traductionnel. Chez la bactérie photosynthétique pourpre non-sulfureuse R. capsulatus, la régulation de l’activité de la nitrogénase nécessite une panoplie de protéines dont la protéine membranaire AmtB, qui est impliquée dans le transport et la perception d’ammonium, et les protéines PII qui jouent plusieurs rôles clés dans la régulation de l’assimilation d’azote. Suite à l’ajout de l’ammonium dans le milieu, une inhibition réversible de l’activité de la nitrogénase est déclenchée via un mécanisme d’ADP-ribosylation de la nitrogénase. La séquestration de GlnK (une protéine PII) par l’AmtB permet à DraT, une ADP-ribosyltransférase, d’ajouter un groupement ADP-ribose sur la protéine-Fe de la nitrogénase l’empêchant ainsi de former un complexe avec la protéine-MoFe. Donc, le transfert d’électrons est bloqué, engendrant ainsi l’inhibition de l’activité de la nitrogénase qui dure aussi long que la concentration d’azote fixé reste élevé, phénomène appelé le « Switch-off/Switch-on » de la nitrogénase. Dans ce mémoire, pour mieux comprendre ce phénomène de régulation, des mutations ponctuelles au niveau de certains résidus conservés de la protéine AmtB, dont D338, G367, H193 et W237, étaient générées par mutagénèse dirigée, afin d’examiner d’avantage leur rôle dans le transport d’ammonium, la formation du complexe AmtB-GlnK, ainsi que dans le « Switch-off » et l’ADP-ribosylation. Les résultats permettent de conclure l’importance et la nécessité de certains résidus telle que le G367 dans la régulation de la nitrogénase et le transport d’ammonium, contrairement au résidu D338 qui ne semble pas être impliqué directement dans la régulation de l’activité de la nitrogénase. Ces résultats suggèrent d’autres hypothèses sur les rôles des acides aminés spécifiques d’AmtB dans ses fonctions comme transporteur et senseur d’ammonium.

Mortuaires suivi de La mort-vivance comme motif d'écriture dans Aurélia de Gérard de Nerval

Dans Mortuaires, une pièce de théâtre en fragments, deux soeurs se rencontrent dans une chambre d'hôtel; Jiji, la plus vieille, vient de retrouver les cendres de leur mère, morte dix ans auparavant; elle voudrait enterrer l'urne définitivement, alors que la plus jeune, Ge, tient à la garder près d'elle. Ce sera l'occasion pour les soeurs de faire valoir leur propre désir et de célébrer la morte, de reprendre contact avec ce qui reste d'elle dans leur mémoire. Le texte se présente sous forme de mini-scènes sans continuité, bien qu’étant toutes reliées, comme un dialogue interrompu, une cérémonie rejouant la mise en pièces du corps. La fragmentation de la mémoire constitue le projet esthétique de la pièce, dont le ressort dramatique tourne autour du souvenir endeuillé et du corps mort. La mort-vivance comme motif d'écriture dans « Aurélia » de Gérard de Nerval est un essai portant sur le rapport qu'entretient Nerval avec les morts dans le récit, ceux-ci constituant son moteur d'écriture. Au moyen de théories telles que la psychanalyse (Freud, Jackson), la sociologie (Muray) et la théorie de la lecture (Picard), il sera démontré que Nerval, dans Aurélia, se fait spirite en faisant revenir les morts au moyen du rêve. L'écriture se pose comme un lieu de rencontre entre les vivants et les morts, un espace dans lequel chacun doit se faire mort-vivant pour aller retrouver l'autre. Les frontières se brouillent et il devient difficile pour Nerval, ainsi que pour le lecteur, de distinguer le rêve de la réalité.

Poly(ethylene-co-acrylic acid) random copolymers : amphiphilic properties and self-assembly in aqueous medium

Les travaux de recherche présentés ici avaient pour objectif principal la synthèse de copolymères statistiques à base d’éthylène et d’acide acrylique (AA). Pour cela, la déprotection des groupements esters d’un copolymère statistique précurseur, le poly(éthylène-co-(tert-butyl)acrylate), a été effectuée par hydrolyse à l’aide d’iodure de triméthylsilyle. La synthèse de ce précurseur est réalisée par polymérisation catalytique en présence d’un système à base de Palladium (Pd). Le deuxième objectif a été d’étudier et de caractériser des polymères synthétisés à l’état solide et en suspension colloïdale. Plusieurs copolymères précurseurs comprenant différents pourcentages molaires en tert-butyl acrylate (4 à 12% molaires) ont été synthétisés avec succès, puis déprotégés par hydrolyse pour obtenir des poly(éthylène-coacide acrylique) (pE-co-AA) avec différentes compositions. Seuls les copolymères comprenant 10% molaire ou plus de AA sont solubles dans le Tétrahydrofurane (THF) et uniquement dans ce solvant. De telles solutions peuvent être dialysées dans l’eau, ce qui conduit à un échange lent entre cette dernière et le THF, et l’autoassemblage du copolymère dans l’eau peut ensuite être étudié. C’est ainsi qu’ont pu être observées des nanoparticules stables dans le temps dont le comportement est sensible au pH et à la température. Les polymères synthétisés ont été caractérisés par Résonance Magnétique Nucléaire (RMN) ainsi que par spectroscopie Infra-Rouge (IR), avant et après déprotection. Les pourcentages molaires d’AA ont été déterminés par combinaison des résultats de RMN et ii de titrages conductimètriques. A l’état solide, les échantillons ont été analysés par Calorimétrie différentielle à balayage (DSC) et par Diffraction des rayons X. Les solutions colloïdales des polymères pE-co-AA ont été caractérisées par Diffusion dynamique de la lumière et par la DSC-haute sensibilité. De la microscopie électronique à transmission (TEM) a permis de visualiser la forme et la taille des nanoparticules.
