Peruskoulun ensimmäisen ja toisen luokan oppilaat ovat opintiensä alussa mutta vielä lähellä varhaislapsuuden leikin ja vapauden maailmaa. Vuodesta 2004 alkaen heillä on ollut lakisääteinen oikeus osallistua koulunjälkeiseen aamu- tai iltapäiväkerhoon. Läksyjenteon, välipalan ja askartelun tai muun ohjatun harrastusmuodon lisäksi kerhossa on mahdollisuus myös vapaaseen leikkiin ja toimintaan. Iltapäiväkerhot ovat niin vanhempien kuin lasten suosima vapaa-ajanviettotapa, jonka valitsevat lähes kaikki 1.-luokkalaisten ja osa 2.-luokkalaisten lasten vanhemmista, vanhempien mukaan erityisesti turvallisuussyistä. Tämän laadullisen, lapsuuden sosiologiaan ja yleiseen sosiologiaan kiinnittyvän, mutta myös kasvatustieteestä ja filosofiasta aihetta lähestyvän pro gradu -työn tavoitteena on tarkastella lasten hyvinvointia ja iltapäiväkerhon kasvatusvuorovaikutusta autonomian, toimijuuden ja sosiaalisuuden näkökulmasta. Aineistoanalyysin selektiivisessä vaiheessa ydinkategorioiksi nousivat auktoriteetin laatu ja valvonnan määrä. Tutkielman empiirinen aineisto koostuu tutkimuskohteeksi satunnaisesti valitun, suuren eteläsuomalaisen kunnan koulun tiloissa järjestetyn iltapäiväkerhon etnografisesta havainnoinnista, 14 lapsen parihaastatteluista ja kymmenelle vanhemmalle lomakkeella esitetyistä kysymyksistä. Analyysimenetelmänä on etnografia ja grounded theoryna tunnettu metodi. Tutkielman perusteella henkilökunnan pedagogisen auktoriteetin laatu ja kasvatusote kuvastavat kasvatuskulttuurien ja lapsuudesta käytävän määrittelyn murrosta, samoin kuin kerhon asemaa koulun ja vapaa-ajan välimaastossa. Vuorovaikutuksessa auktoriteetin laatu näyttäytyy enemmän autoritäärisena kuin neuvottelevana ja osallistavana, mutta on sekoitus molempia. Lasten autonomisuus ja osallisuus toteutuvat aineiston valossa puutteellisesti. Myös lasten käsitys ja tieto oikeuksistaan tuoda esiin mielipiteensä on epävarmaa. Jatkuva valvonta ja toiminnan muutokset edellyttävät lapsilta herkeämätöntä reagointi- ja muutosvalmiutta, mikä ei vastaa iltapäiväkerhoille asetettujen toiminnan perusteiden mukaista rentoutumisen, virkistyksen tai levon toteutumista. Toisaalta vertaissuhteilla on suuri rooli lasten voimavarana tiukan aikuisjohtoisessa toimintaympäristössä. Toimijuutta ilmentävä, vaikeasti havaittava ja monia muotoja saava lasten keskinäinen vertaiskulttuuri toimii yhdistävänä siteenä lasten välillä ja vahvistaa heidän keskinäistä sosiaalisuuttaan ja yhteenkuuluvuuttaan. Samalla se korostaa lasten ja aikuisten suhteen hierarkkisuutta ja vastakkaisuutta yhteistoiminnan sijaan. Tutkielma jättää avoimeksi kysymyksen auktoriteetin laadun ja valvonnan määrän vaikutuksesta iltapäiväkerholapsiin ja heidän myöhempään kasvuunsa itseensä luottaviksi, autonomisiksi kansalaisiksi nopeasti muuttuvassa maailmassa. Jatkuvan konfliktin uhan alainen ilmapiiri ei edesauta luottamuksellisen ilmapiirin syntymistä. Kasvatusinstituutiossa välttämätön auktoriteetti voi olla monenlaista, autonomiaa ja luottamusta edistävää, yksipuolista kurikasvatusta tai epäröivä sekoitus molempia. Sen laadulla ja määrällä on merkitystä iltapäiväkerholasten hyvinvoinnin kannalta. Koulun jälkeisessä iltapäivässä lasten vapaan toiminnan, levon ja liikunnan mahdollisuuksiin, riittäviin ja tarkoituksenmukaisiin toimintatiloihin ja ohjaajien kasvatusvalmiuksiin tulee tämän tutkielman valossa myös kiinnittää nykyistä enemmän huomiota.

Nybildning av blodkärl från tidigare existerande kärl, angiogenes, är ett väsentligt skede vid tumörtillväxt. Denna process regleras av bland annat tillväxtfaktorer, var av den vaskulära endoteliala tillväxtfaktorn har en central roll. Hämning av angiogenes kan ske antingen extracellulärt med hjälp av humaniserade monoklonala antikroppar eller intracellulärt med hjälp av småmolekylära hämmaren. Sunitinib är en småmolekylär multikinashämmare och inhiberar flera tyrosinkinasreceptorer som påverkar tumörtillväxten och metastasutvecklingen vid cancer. Sunitinibs främsta indikationer är gastrointestinala stromacellstumörer, metastaserad njurcellscancer och neuroendokrina tumörer i bukspottskörteln. Behandling med tyrosinkinashämmare orsakar biverkningar som hypertension, kardiotoxicitet och njursvikt, vilka antas bero på de hämmande effekterna på mål som inte är väsentliga för anti-cancer-aktiviteten (”off-target” biverkningar). Bland annat AMP-aktiverat proteinkinas (AMPK), ett kinas som upprätthåller metabolisk homeostas i hjärtat, inhiberas av sunitinib och antas framkalla kardiovaskulära biverkningar. För att reducera ”off-target” biverkningar strävar man till att hitta alternativ som minskar de skadliga effekterna utan att den terapeutiska aktiviteten försvagas. Bland annat ett begränsat kaloriintag har uppvisat skyddande effekt på hjärtat via mekanismer sammankopplade till ökad resistens mot oxidativ stress, inflammation och mitokondriell dysfunktion, samt avtagande apoptos och autofagi. Detta sker delvis genom aktivering av enzymet Sirt1. Syftet med den här studien var att undersöka ifall kaloribegränsning skyddar mot kardiovaskulära och renala biverkningar inducerade av sunitinib hos råttor. Dessutom studerades vilka signalkedjor i cellen som medverkar. I studien användes 40 spontant hypertensiva råttor samt 10 normotensiva Wistar-Kyoto råttor. Försöksdjuren delades in i fem grupper beroende på behandling; I WKY kontroll, II SHR kontroll, III SHR + kaloribegränsning 70 %, IV SHR + sunitinib 3 mg/kg och V SHR + sunitinib 3 mg/kg + kaloribegränsning 70 %. Behandlingsperioden var åtta veckor. Blodtrycket mättes varje vecka med svansmanchett, urinutsöndringen undersöktes vecka 4 och vecka 8 med metabolismburar, ultraljudsundersökning av hjärtat utfördes sista veckan och blodkärlens respons till acetylkolin och natriumnitroprussid studerades i samband med avlivning. Proteinerna Sirt1 och AMPK analyserades i hjärtat med Western blotting samt förekomsten av makrofagmarkören ED1 i njurarna med immunhistokemi. Studien visade att sunitinibdosen 3 mg/kg är mycket väl tolererbar hos råttor eftersom sunitinib inte orsakade högre blodtryck, kraftigare hypertrofi eller mer omfattande njurskada jämfört med obehandlade SHR- grupper. Utgående från resultaten kan man också konstatera att kaloribegränsningen har positiva kardiovaskulära effekter.

El presente estudio supone un intento de describir y analizar el uso de la preposición "de" sobre la base de un corpus diacrónico, con énfasis en las diferentes relaciones semánticas que establece. Partiendo de un total de más de 16.000 casos de "de" hemos establecido 48 categorías de uso, que corresponden a cuatro tipos de construcción sintáctica, a saber, el uso de "de" como complemento de nombres (CN), verbos (CV), adjetivos (CA) y, finalmente, su uso como núcleo de expresiones adverbiales independientes (CI). El estudio consta de tres partes fundamentales. En la parte I, se introduce la Lingüística Cognitiva, que constituye la base teórica esencial del trabajo. Más exactamente, se introducen conceptos como la teoría del prototipo, la teoría de las metáforas conceptuales y la gramática cognitiva, especialmente las ideas de "punto de referencia" y "relación intrínseca" (Langacker 1995, 1999). La parte II incluye el análisis de las 48 categorías. En esta parte se presentan y comentan casi 2.000 ejemplos del uso contextual de "de" extraídos del corpus diacrónico. Los resultados más importantes del análisis pueden resumirse en los siguientes puntos: El uso de "de" sigue siendo esencialmente el mismo en la actualidad que hace 800 años, en el sentido de que todas las 48 categorías se identifican en todas las épocas del corpus. El uso de "de" como complemento nominal va aumentando, al contrario de lo que ocurre con su uso como complemento verbal. En el contexto nominal son especialmente las relaciones posesivas más abstractas las que se hacen más frecuentes, mientras que en el contexto verbal las relaciones que se hacen menos frecuentes son las de separación/alejamiento, causa, agente y partitivo indefinido. Destaca la importancia del siglo XVIII como época de transición entre un primer estado de las cosas y otro posterior, en especial en relación con el carácter cada vez más abstracto de las relaciones posesivas así como con la disminución de las categorías adverbales de causa, agente y partitivo. Pese a la variación en el contexto inmediato de uso, el núcleo semántico de "de" se mantiene inalterado. La parte III toma como punto de partida los resultados del análisis de la parte II, tratando de deslindar el aporte semántico de la preposición "de" a su contexto de uso del valor de la relación en conjunto. Así, recurriendo a la metodología para determinar el significado básico y la metodología para determinar lo que constituyen significados distintos de una preposición (Tyler , Evans 2003a, 2003b), se llega a la hipótesis de que "de" posee cuatro significados básicos, a saber, 'punto de partida', 'tema/asunto', 'parte/todo' y 'posesión'. Esta hipótesis, basada en las metodologías de Tyler y Evans y en los resultados del análisis de corpus, se intenta verificar empíricamente mediante el uso de dos cuestionarios destinados a averiguar hasta qué punto las distinciones semánticas a las que se llega por vía teórica son reconocidas por los hablantes nativos de la lengua (cf. Raukko 2003). El resultado conjunto de los dos acercamientos tanto refuerza como especifica la hipótesis. Los datos que arroja el análisis de los cuestionarios parecen reforzar la idea de que el núcleo semántico de "de" es complejo, constando de los cuatro valores mencionados. Sin embargo, cada uno de estos valores básicos constituye un prototipo local, en torno al cual se construye un complejo de matices semánticos derivados del prototipo. La idea final es que los hablantes son conscientes de los cuatro postulados valores básicos, pero que también distinguen matices más detallados, como son las ideas de 'causa', 'agente', 'instrumento', 'finalidad', 'cualidad', etc. Es decir, "de" constituye un elemento polisémico complejo cuya estructura semántica puede describirse como una semejanza de familia centrada en cuatro valores básicos en torno a los cuales se encuentra una serie de matices más específicos, que también constituyen valores propios de la preposición. Creemos, además, que esta caracterización semántica es válida para todas las épocas de la historia del español, con unas pequeñas modificaciones en el peso relativo de los distintos matices, lo cual está relacionado con la observada variación diacrónica en el uso de "de".

Pappret conceptualizes parsning med Constraint Grammar på ett nytt sätt som en process med två viktiga representationer. En representation innehåller lokala tvetydighet och den andra sammanfattar egenskaperna hos den lokala tvetydighet klasser. Båda representationer manipuleras med ren finite-state metoder, men deras samtrafik är en ad hoc -tillämpning av rationella potensserier. Den nya tolkningen av parsning systemet har flera praktiska fördelar, bland annat det inåt deterministiska sättet att beräkna, representera och räkna om alla potentiella tillämpningar av reglerna i meningen.

The aim of the study is to investigate the use of finlandisms in an historical perspective, how they have been viewed from the mid-19th century to this day, and the effect of language planning on their use. A finlandism is a word, a phrase, or a structure that is used only in the Swedish varieties used in Finland (i.e. in Finland Swedish), or used in these varieties in a different meaning than in the Swedish used in Sweden. Various aspects of Finland-Swedish language planning are discussed in relation to language planning generally; in addition, the relation of Finland Swedish to Standard Swedish and standard regional varieties is discussed, and various types of finlandisms are analysed in detail. A comprehensive picture is provided of the emergence and evolution of the ideology of language planning from the mid-19th century up until today. A theoretical model of corpus planning is presented and its effect on linguistic praxis described. One result of the study is that the belief among Finland-Swedish language planners that the Swedish language in Finland must not be allowed to become distanced from Standard Swedish, has been widely adopted by the average Finland Swede, particularly during the interwar period, following the publication of Hugo Bergroth s work Finlandssvenska in 1917. Criticism of this language-planning ideology started to appear in the 1950s, and intensified in the 1970s. However, language planning and the basis for this conception of language continue to enjoy strong support among Swedish-speaking Finns. I show that the editing of Finnish literary texts written in Swedish has often been somewhat amateurish and the results not always linguistically appropriate, and that Swedish publishers have in fact adopted a rather liberal attitude towards finlandisms. My conclusion is that language planning has achieved rather modest results in its resistance to finlandisms. Most of the finlandisms used in 1915 were still in use in 2005. Finlandisms occur among speakers of all ages, and even among academically educated people despite their more elevated style. The most common finlandisms were used by informants of all ages. The ones that are firmly rooted are the most established, in other words those that are stylistically neutral, seemingly genuinely Swedish, but which are nevertheless strongly supported by Finnish, and display a shift in meaning as compared with Standard Swedish.

Pro gradu -tutkielmassani tarkastelen diasporia ja niihin kohdistuvaa kansainvälistä sääntelyä. Diasporilla tarkoitan valtion rajojen ulkopuolella asuvia ihmisiä, joilla on jokin, esimerkiksi etninen tai kieliside tuohon valtioon. Valtiolla puolestaan voi olla jokin intressi suhteessa diasporaansa. Diasporiin liittyvät kysymykset ovat ajankohtaisia globaalissa maailmassa, jossa ihmisillä on entistä enemmän mahdollisuuksia pitää siteitä yllä useampaan kuin yhteen valtioon. Diasporien ohella kirjallisuudessa puhutaan myös kin-state -problematiikasta, kun viitataan valtioiden harjoittamaan politiikkaan, joka pyrkii vaikuttamaan toisen valtion alueella asuvien tai oleskelevien ihmisten asemaan. Tutkimuksen teoreettinen viitekehys on englantilaisen koulukunnan ajatus kansainvälisestä yhteisöstä ja sille keskeisistä primaari-instituutioista, kuten valtiosuvereniteetti ja kansainvälinen oikeus. Se, miten valtio politiikassaan suhtautuu instituutioihin, kertoo valtion suhteesta kansainväliseen yhteisöön yleensä. Instituutioita voidaan puolestaan tarkastella tiettyjen kapea-alaisempien normien, sekundaari-instituutioiden, valossa. Edellä mainittuna sekundaari-instituutiona esitellään tutkielmassa se kansainvälinen normisto, joka vaikuttaa diasporien asemaan valtioiden välisessä politiikassa. Normisto perustuu Yhdistyneiden kansakuntien, Euroopan neuvoston ja ETYJ:n sopimuksiin ja suosituksiin. Kansainvälisen oikeuden lähtökohta on, ettei valtio voi puuttua diasporakseen katsomiensa ihmisten asemaan toisessa valtiossa edes ääritapauksessa, jossa asuinvaltio epäonnistuu tehtävässään suojella toisen valtion kansalaisia tai vähemmistöjään. Reagointivastuu on kansainvälisellä yhteisöllä – vaikka interventiota ulkomailla olevien kansalaisten suojelemiseksi onkin suoritettu sekä kylmän sodan aikana että sen jälkeen. Interventiot eivät ole diasporapolitiikan ainoa muoto ja monilla valtioilla onkin niin sanottuja diasporalakeja, joiden puitteissa ne voivat vaikuttaa diasporiensa asemaan. Koulutukseen ja kulttuuriin liittyvä tuki on eurooppalaisissa suosituksissa katsottu hyväksyttäväksi, mutta muiden tukimuotojen ulottamista diasporiin tulee harkita ja soveltaa vain erityistapauksissa, jos politiikalla on valtion toimivallan ulkopuolella vaikuttavia seurauksia. Tutkimus näyttää, että diasporakysymysten sääntely on kansainvälisessä yhteisössä vielä osin määrittelemätöntä sekä altista valtioiden tulkinnoille. Esimerkkinä valtioiden tulkinnoista ja niiden harjoittamasta diasporapolitiikasta tarkastellaan Venäjän federaation politiikkaa, sillä Venäjän ulkopolitiikassa esillä pidetty kiinnostus suojella ulkomailla olevia kansalaisia ja maanmiehiä on herättänyt myös kansainvälistä huomiota. Venäjän politiikan tarkastelu luo kontekstin, jossa tutkielman varsinaista kiinnostuksenkohdetta, Suomen venäläisen diasporan asemaa, on mahdollista tarkastella. Tutkimusaineistoa ovat Venäjän johdon lausunnot liittyen viimeaikaisiin Suomen ja Venäjän välisiin nk. lapsikiistoihin. Teoriaohjaava sisällönanalyysi aineistosta esittää, että vaikka vihjeitä politiikassa yleisesti esiintyvästä nk. suojelupuheesta on havaittavissa myös Suomen venäläisen vähemmistön asemaan liittyen, ei Venäjä lapsikiistoissa kuitenkaan suoraan loukannut Suomen suvereniteettia tai kansainvälistä oikeutta. Tiettyjen puhetapojen ja esimerkiksi lapsiasiamies Astahovin toiminnan voidaan kuitenkin tulkita olevan kansainvälisen normiston vastaisia ja siten myös loukkaavan suvereniteettia ja kansainvälisen oikeuden henkeä. Teoreettisen viitekehyksen tehtävä oli ensisijaisesti antaa näkökulmia aineiston tarkasteluun. Venäjän politiikan suhde suvereniteettiin ja kansainväliseen oikeuteen suhteessa tässä tarkasteltuun politiikkakysymykseen kertoo kuitenkin myös Venäjän asemasta kansainvälisen yhteisön jäsenenä. Diasporanormistoon sitoutuminen osoittaa Venäjän sitoutuneen ainakin periaatteellisella tasolla solidaristiseen, yhteisiä normeja jakavaan kansainväliseen yhteisöön – toisaalta Venäjän viime vuosien politiikka kuitenkin osoittaa Venäjän samalla haastavan myös pluralistisille yhteisöille keskeisiä valtiosuvereniteetin ja kansainvälisen oikeuden noudattamisen periaatteita.

The voluntary associations dealt with in this dissertation were ethnic clubs and societies promoting the interests of German immigrants in Finland and Sweden. The associations were founded at the end of the 19th century as well as at the beginning of the 20th century during a time in which migration was high, the civil society grew rapidly and nationalism flourished. The work includes over 70 different associations in Finland and Sweden with a number of members ranging from ten to at most 2, 500. The largest and most important associations were situated in Helsinki and Stockholm where also most of the German immigrants lived. The main aim of this work is to explore to what extent and how the changes in government in Germany during 1910 to 1950 were reflected in the structures and participants, financial resources and meeting places, networks and activities of the German associations in Finland and Sweden. The study also deals with how a collective German national identity was created within the German associations. The period between 1910 and 1950 has been described by Hobsbawm as the apogee of nationalism. Nationalism and transnationalism are therefore key elements in the work. Additionally the research deals with theories about associations, networking and identity. The analysis is mostly based on minutes of meetings, descriptions of festivities, annual reports and historical outlines about the associations. Archival sources from the German legations, the German Foreign Office, and Finnish and Swedish officials such as the police and the Foreign Offices are also used. The study shows that the collective national identity in the associations during the Weimar Republic mostly went back to the time of the Wilhelmine Empire. It is argued that this fact, the cultural propaganda and the aims of the Weimar Republic to strengthen the contacts between Germany and the German associations abroad, and the role of the German legations and envoys finally helped the small groups of NSDAP to infiltrate, systematically coordinate and finally centralize the German associational life in Finland and Sweden. The Gleichschaltung did not go as smoothly as the party wanted, though. There was a small but consistent opposition that continued to exist in Finland until 1941 and in Sweden until 1945. The collective national identity was displayed much more in Sweden than in Finland, where the associations kept a lower profile. The reasons for the profile differences can be found in the smaller number of German immigrants in Finland and the greater German propaganda in Sweden, but also in the Finnish association act from 1919 and the changes in it during the 1920s and 1930s. Finally, the research shows how the loss of two world wars influenced the associations. It argues that 1918 made the German associations more vulnerable to influence from Germany, whereas 1945 brought the associational life back to where it once started as welfare, recreational and school associations.

Effektutvärdering inom företagandeutbildning är ett forskningsfält som karakteriseras av brist på modeller ifråga om utvärdering. De få och hittills existerande utvärderingsmodellerna verkar ha förbisett de pedagogiska variablerna såsom utbildningens innehåll och metoder. Därför har det varit problematiskt att beskriva företagandeutbildningen i högskolor och analysera hur företagandeutbildningen bidrar till studerandes inlärning och deras förmåga att utnyttja kunskapen i näringslivet. Avhandlingen som är en deduktiv studie granskar den tidigare forskningen på området och förespråkar en tvärvetenskaplig ansats vid mätning och presentation aveffekter inom företagandeutbildning. Den nya modellen, ROEE-modellen, bidrar till teoribildningen om lärandets ”vad” och lärandets ”hur” inom företagandeutbildningen. En av de första teorierna om inlärning (Herbart 1776-1841) och Kirkpatricks (1998) fyra-stegs modell för kursutvärdering byggs ut med en ny referensram baserad på examensutbildning inom företagande. En intressant aspekt metodmässigt utgör att försöksplanering och diagnostik inom medicinens område tillämpas på företagandeutbildningen. Avhandlingen visar att variabeln innehåll i företagandeutbildningen inom examensutbildning har en klar koppling till beteendet. Ett välavvägt innehåll kan utnyttjas i arbetslivet såväl av entreprenören som av intraprenören. Vid metodval i undervisningen visar den empiriska undersökningen att variation i metoder ger de positivaste upplevelserna.

This thesis explores the link between South-South remittance and development. It attempts to establish improved understanding about the role of immigrants as agents of constituency growth and development. By doing so, it illuminates the dark corners of the policy implications that the unconventional development agency of immigrants might have for countries in the Organization ft Economic Cooperation and Development (OECD). The thesis problematises the existence of state-centric international cooperation as providing the recipe for failed Aid in the face of global poverty menace. In the last half a century, the relative shi' of focus to non-state actors brought about the proliferation of NGOs. That, intrun, helped improve international access to crisis situations; however, their long-term remedial impacts on poverty and development have been contested. Major misgivings for non-governmental organizations (NGOs) are, on one hand, low level goal-bound expenditures and lack of independence from influence of the state, on the other. Therefore, the thesis enterprises to empirically verify its fundamental question whether remitting immigrants constitute an alternative development agency to the traditional players: the State and NGOs. Its main arguments are: due to state's failures in bringing sustainable development in many countries of the South, the future of poverty reduction and development also rests in immigrants' remittances. Nonetheless, in the last decade, remittance security-nexus dominated its discourse. Because of that remittance was viewed as something requiring global regime and restrictions. These temptations to tightly regulate remittance flows carry the danger of overlooking its trans-boundary nature and its strong link with livelihood of the poor. Therefore, to avoid unintended consequences of interventions, there need to be clear policy that bases itself on a discursive knowledge on the issues of North-South and South-South remittances The study involved both literature based and empirical research. It employed Discourse Analysis (C as main method for the former and snow-balling as its approach for the latter. For the first part the thesis constructed three conceptual models, these are: metrological model, police model and ecological model on remittance development-nexus. Through this modeling, the thesis achieved better deconstruction on the concepts remittance, immigrants and development agency. The protagonists of each model, the values and interests they represent, and their main arguments along various lines of dichotomies have been discussed. For instance, the main treats of meteorological model include: it sees remittance as transitional economic variable which require constant speculations and global management; it acts as meteorological station for following up or predicting the level, direction, flow and movement of global remittance. It focuses on official lines and considers the state as legitimate recipient of advic and positive consequence of remittance. On the other hand, police model views remittance as beir at best, development neutral or as an illicit activity requiring global regulations and tight control. Both immigrants and remittance viewed as subversive to establishments. It gives primacy to state stable agent of development and a partner for international cooperation. The anti-thesis to the police model is supplied by ecological model, which this thesis is a part. Ecological model on remittance and immigrants argues that, tight global regulations alone cannot be a panacea for possible abuse of informal remittance system. Ecological model, not only links remittance to poverty reduction, the main trust of development, but also considers the development agency of immigrants as critical factor for 21st century north-south development intervention. It sees immigrants as development conscious and their remittance instrument as most stable flow of finance to the developing countries. Besides, it sees remittance as effective poverty solutions than Foreign Direct Investment and international AID. This thesis focuses on the significance of South-South remittance and investigates the South Africa - Ethiopia remittance corridor, as case study; and empirically verifies the role of Ethiopian (Kembata and Hadiya) immigrants in South Africa as agents of local development back home. The study involved techniques of interview, group discussions, observations and investigative study. It also looked into the determinants of their migration to South Africa, and their remittance to Ethiopia. The theoretical models in the first part of the thesis have been operationalised throughout the empirical part to verify if the Kembata and Hadiya immigrants played the crucial role in their household poverty and local development in comparison with the Ethiopian state and the NGOs involved in the system. As evidenced by the research the thesis has made three distinct contributions to the discourse of remittance development-nexus. Fist, it systematized the debate about linkages between remittance, immigrants, development agency and policy of international cooperation by creating three conceptual models (school of thoughts); second, it singled out remitting immigrants as new agents of development in the South; third, it deconstructed concept of remittance and established South¬South remittance as additional sphere of academic investigation. In addition to the above contributions, the thesis finds that Kembata and Hadiya immigrants have engaged in various developmental activities in their locality than usually anticipated. Hence, it concludes that Ethiopian immigrants constitute an alternative development agency to the state and other non-state actors in their country, and the lesson can be applied to poverty reduction strategies in most developing countries.

The purpose of this research was to investigate the role of electronic word of mouth (eWOM) in shaping consumer attitudes towards various products and services with concentration on the consumer attitude change. eWOM has long been proven to play an important role in influencing consumer attitudes and has been researched from a variety of perspectives. This study attempts to look deeper into the process of consumer attitude change by applying as the central theory of the study the Elaboration Likelihood Model of Persuasion by Petty and Cacioppo. In the processes of examining the background academic and empirical research the Internet and Web 2.0 are closely depicted in order to understand how throughout the past centuries technology allowed the rise of various mediums where consumers can not only share their opinions online about products and services but also communicate with other consumers. Manuel Castel’s Internet Galaxy, Gildin’s, Carl and Noland’s, Hennig-Thurau, Gwinner, Walsh and Gremler’s researches on eWOM are the central works that helped to shape both the theoretical and empirical parts of this study. The mixed method approach was chosen as a research method for this study. An online survey was conducted via the Surveymonkey.com platform and eight qualitative in-depth interviews were conducted. The results of the study show that central route queues as text quality and text argumentativeness are more prominent among the research subjects and the peripheral route queues: source credibility and source expertise did not show considerable significance. Also more experience and participation consumers have with user-rating websites and applications more inclined they are to elaborate on the central route cues and are more likely to search for opinions that they consider rational and credible. Also these respondents are less inclined to search for ratings that confirm their existing beliefs about products or services. Less experience/participation they have about eWOM more likely they are to search for reviews confirmatory to their own.

Worldwide and notably in the developed countries, cancer is an increasing cause of morbidity and mortality, being the second most common cause of death after ischemic heart disease. Now and in the future new cancer cases need to be diagnosed earlier. Prognostic factors may be helpful in recognizing and handling those patients who need more aggressive therapy, and it is also desirable to predict treatment response accurately. Cancerous inhibitor of protein phosphatase 2A (CIP2A) is an oncoprotein predominantly expressed in malignant tissues and inhibiting protein phosphatase 2A (PP2A) activity; it is a promising target for cancer therapy. The aim of this thesis was to evaluate the prognostic role of CIP2A in solid cancers, and for this purpose to explore expression of CIP2A, and investigating regulation of CIP2A in order to gain insight into signalling pathways leading to alteration in prognosis. Patients diagnosed with gastric, serous ovarian, tongue, or colorectal cancer at Helsinki University Central Hospital were included. Tumour tissue microarrays assembled from specimens from these patients were prepared and stained immunohistochemically for CIP2A protein expression. Associations with clinicopathologic parameters and other biomarkers were explored, and survival analyses were done according to the Kaplan-Meier method. Study of the role of CIP2A in intracellular signalling in vitro involved gastric, ovarian, and tongue cancer cell lines. We found CIP2A to be highly expressed in gastric, ovarian, tongue, and colorectal cancer specimens. CIP2A was associated with clinicopathologic parameters characterizing an aggressive disease, namely advanced stage, high grade, p53 immunopositivity, and high proliferation index. CIP2A led to recognition of gastric, ovarian, and tongue cancer patients with poor prognosis, however, with a cancer type-specific cut-off level for prognostic significance. In tongue cancer, it served as an independent prognostic marker. In contrast, in colorectal cancer, CIP2A provided no prognostic value. In cancer cell lines, CIP2A was highly expressed at both protein and mRNA levels, and promoted cell proliferation and anchorage-independent growth. In gastric cancer, we demonstrated with a MYCER construct in mouse embryo fibroblasts that activation of MYC led to increased CIP2A mRNA expression, and hence we suggested that a positive feedback mechanism between CIP2A and MYC may potentiate and prolong the oncogenic activity of these proteins. We demonstrated in ovarian cancer an association between CIP2A and EGFR protein overexpression and EGFR gene amplification. In ovarian and tongue cancer cells we showed that depletion of EGFR downregulates CIP2A expression. In conclusion, high CIP2A expression occurred frequently among patients with aggressive disease. CIP2A may serve as a prognostic marker in gastric, ovarian, and tongue cancer and thus may help in tailoring therapy for cancer patients. The positive feedback mechanism between CIP2A and MYC, as well as the positive regulation of CIP2A by EGFR, are a few signalling pathways regulating and regulated by CIP2A. These and other mechanisms need to be studied further, however. CIP2A is a potential target for therapy, and its potential role as predictive marker and as a tumour marker in serum requires exploration.

ABSTRACT Idiopathic developmental disorders (DDs) affect ~1% of the population worldwide. This being a considerable amount, efforts are being made to elucidate the disease mechanisms. One or several genetic factors cause 30-40% of DDs, and only 10% are caused by environmental factors. The remaining 50% of DD patients go undiagnosed, mostly due to a lack of diagnostic techniques. The cause in most undiagnosed cases is though to be a genetic factor or a combination of genetic and environmental factors. Despite the surge of new technologies entering the market, their implementation into diagnostic laboratories is hampered by costs, lack of information about the expected diagnostic yield, and the wide range of selection. This study evaluates new microarray methods in diagnosing idiopathic DDs, providing information about their added diagnostic value. Study I analysed 150 patients by array comparative genomic hybridization (array CGH, 44K and 244K), with a subsequent 18% diagnostic yield. These results are supported by other studies, indicating an enourmous added diagnostic value of array CGH, compared with conventional cytogenetic analysis. Nevertheless, 80% of the patients remained undiagnosed in Study I. In an effort to diagnose more patients, in Study IV the resolution was increased from 8.9 Kb of the 244K CGH array to 0.7 Kb, by using a single-nucleotide polymorphism (SNP) array. However, no additional pathogenic changes were detected in the 35 patients assessed, and thus, for diagnostic purposes, an array platform with ca 9 Kb resolution appears adequate. The recent vast increase in reports of detected aberrations and associated phenotypes has enabled characterization of several new syndromes first based on a common aberration and thereafter by delineation of common clinical characteristics. In Study II, a familial deletion at 9q22.2q22.32 with variable penetrance was described. Despite several reports of aberrations in the adjacent area at 9q associated with Gorlin syndrome, the patients in this family had a unique phenotype and did not present with the syndrome. In Study III, a familial duplication of chromosome 6p22.2 was described. The duplication caused increased expression of an important enzyme of the γ-aminobutyric acid (GABA) degradation pathway, causing oxidative stress of the brain, and thus, very likely, the mild mental retardation of these patients. These two case studies attempted to pinpoint candidate genes and to resolve the pathogenic mechanism causing the clinical characteristics of the patients. Presenting rare genetic and clinical findings to the international science and medical community enables interpretation of similar findings in other patients. The added value of molecular karyotyping in patients with idiopathic DD is evident. As a first line of testing, arrays with a median resolution of at least 9 Kb should be considered and further characterization of detected aberrations undertaken when possible. Diagnostic whole-exome sequencing may be the best option for patients who remain undiagnosed after high-resolution array analysis.
