Asiakkaan ja asiantuntijan pedagoginen suhde : Fenomenologinen tutkimus fysioterapiatilanteista asiakkaiden ja fysioterapeuttien kokemana

Väitöskirja on fenomenologinen tutkimus koetusta asiakas-asiantuntijasuhteesta. Tutkimuksen tarkoituksena on selvittää ihmisten välisiä asiakas-asiantuntijatilanteiden suhteita ja siten mahdollistaa asiakkaan hyvinvointia. Tutkimuskohteena on fysioterapiasuhde, jota aiemmin on selvitetty fysioterapeutin parantamisena, asiakkaan terveyden edistämisenä tai vuorovaikutussuhteena. Tässä tutkimuksessa mielenkiinto kohdistuu fysioterapiatilanteissa koettuihin asiakkaiden ja asiantuntijoiden välisiin suhteisiin. Tutkimukseen osallistuivat 16 fysioterapiatilanteen kokenutta asiakasta ja 16 saman tilanteen kokenutta fysioterapeuttia, jotka toimivat tutkimusajankohtana erikoissairaanhoidossa, kunnan terveyskeskuksessa tai yksityisessä fysioterapialaitoksessa. Avoimen yksilöhaastattelun tehtävänä oli kuvata mitä osanottaja koki juuri päättyneessä tilanteessa. Tutkimusaineiston analyysi etenee ensimmäisessä vaiheessa fenomenologisen tutkimuksen mukaan, yksilöllisten ihmisten välisten suhteiden koettujen merkitysten ja merkityskokonaisuuksien analyysiin ja merkitysperspektiivin synteesiin. Tutkimuksen ensimmäisen vaiheen yksilöllisten merkitysperspektiivien perusteella fysioterapiasuhde osoittautui muutossuhteeksi, mikä ei ollut erilainen eri organisaatioissa, vaan siinä ilmeni pedagogisen suhteen oppimisen ja ohjauksen piirteitä. Tutkimuksen toisessa vaiheessa vietiin pedagogisen suhteen mukaisesti yhteen ja vertailtiin yksilöllisten merkitysperspektiivien merkityksiä ja merkityskokonaisuuksia asiakkaiden ja fysioterapian asiantuntijoiden näkökulmina sekä saman tilanteen yhteisenä koettuna näkökulmana. Asiakkaiden näkökulmasta suhteen voimavarana oli hänen kokema kehollinen vieraus, mikä ohjasi asiakas-asiantuntijasuhdetta neljänlaiseen asiakkaan muutossuhteeseen. Fysioterapian asiantuntijoiden näkökulmasta asiaosaamisena oli asiakkaan parantaminen liikkeen tai toiminnan avulla, mikä ohjasi asiakas-asiantuntijasuhdetta asiantuntijan näkökulmasta erilaisiin ohjaussuhteisiin. Samassa tilanteessa asiakkaiden ja asiantuntijan yhteisenä kokemat aukeamat etenivät spontaaneista turvallisuuden ja luottavaisuuden aukeamista aktiivisiin yhteisymmärryksen ja yhteissanoituksen aukeamiin. Pedagoginen suhde avautui merkityskokonaisuuksina joko vain asiakkaalle tai asiantuntijalle tai yhteisenä koettuina pedagogisina aukeamina. Edellä mainituista kolmesta (asiakkaan, asiantuntijan, yhteisenä koettu) näkökulmasta asiakas-asiantuntijasuhde osoittautui tässä tutkimuksessa neljäksi erilaiseksi asiakkaan, asiantuntijan ja yhteytenä koetun näkökulmia yhdistäväksi pedagogiseksi prosessiksi. Tutkimuksen tulosten synteesi osoitti, että pedagogisen prosessin suuntaa muuttavat yhteytenä koettujen aukeamien väliset dialogit, joissa spontaani, yhdessä näkyvä ja yhdessä koettua sanoittava dialogihetket osoittautuivat pedagogista prosessia kääntäviksi mahdollisuuksiksi. Tämän tutkimuksen mukaan vasta aktiivinen yhteistä kieltä tuottava pedagoginen suhde mahdollistaa asiakkaan kokeman kehollisen vierauden ymmärtämisen ja yhteissanoittamisen. Sanoittamalla kokemaansa asiakas voi jakaa kokemaansa toimimattomuutta tutulla kielellä myös muiden kun tilanteessa olleiden kanssa ja siten oppia itsenäisesti ohjaamaan omaa hyvinvointiaan. Tämän tutkimusten tulosten mukaan vain yhdessä (Pentin ja Sarin) tilanteessa pedagoginen prosessi eteni yhteiseksi kieleksi. Tutkimustulokset haastavat kehittämään asiakas-asiantuntijasuhdetta siten, että pedagoginen prosessi voisi toteutua kokonaisuudessaan.

Issues in socially desirable responding and personality research

The four studies presented in this dissertation were designed to examine the influence of socially desirable responding (SDR) on personality research outcomes. The assessment of personality relies heavily on the use of self-report questionnaires. Their validity could be threatened by people being dishonest in their self-descriptions and ascribing more desirable traits to themselves than would be warranted by their behaviour. Scales designed to detect SDR have been around for half a century, but their status continues to be debated. Paulhus (1991) Balanced Inventory of Desirable Responding (BIDR) is perhaps the most prominent of the scales developed to distinguish between those individuals who have distorted their responses and those who have not. The first two studies included in this dissertation mostly deal with the properties of the BIDR. The other two studies are less focused on SDR scales and investigate, more generally, the potential effects of SDR on two phenomena that are of central interest to the general personality discourse personality stability over time and volunteering as participants in psychological research. The data of Studies I and II showed that Paulhus BIDR scales, designed to be indicators of SDR, are not pure measures both the communion management and self-deceptive enhancement scales are, at once, measures of response bias and measures of more substantive individual differences in behaviour. The data further suggested that the communion management and self-deceptive enhancement scales of the BIDR are somewhat accurate measures of communal and agentic bias, respectively. No evidence for a suppressor model of SDR, and only weak evidence for a moderator model, was found in those studies. Concerning research on personality stability, some data in Study I suggested that SDR may add reliable and common variance to a personality questionnaire administered at two different points in time, thus artificially inflating the test-retest correlation of that questionnaire. Furthermore, Study III demonstrated that the maturity-stability hypothesis may be in part, but not entirely, a product of SDR. Study IV suggested that some of the observed personality differences between research volunteers and nonvolunteers may be due to heightened SDR of volunteers. However, those personality differences were by no means exclusively attributable to differences in SDR. In sum, the work presented in this thesis reveals some ambiguity regarding the effects of SDR on personality research, as is true of much of the previous research on SDR. Clear-cut conclusions are difficult to reach, as the data were neither fully consistent with the view that SDR can be ignored, nor with the view that SDR needs to be controlled in some way. The struggle to understand the influence of SDR on personality research continues.

Lionhearts of the Playworld : An ethnographic case study of the development of agency in play pedagogy

This is an ethnographic case study of the creation and emergence of a playworld – a pedagogical approach aimed at promoting children’s development and learning in early education settings through the use of play and drama. The data was collected in a Finnish experimental mixed-age elementary school classroom in the school year 2003-2004. In the playworld students and teachers explore different social and cultural phenomena through taking on the roles of characters from a story or a piece of literature and acting inside the frames of an improvised plot. The thesis takes under scrutiny the notion of agency in education. It produces theoretically grounded empirical knowledge of the ways in which children struggle to become recognized and agentive actors in early education settings and how their agency develops in their interaction with adults. The study builds on the activity theoretical and sociocultural tradition and develops a methodological framework called video-based narrative interaction analysis for studying student agency as developing over time but manifesting through the situational material and discursive local interactions. The research questions are: 1. What are the children’s ways of enacting their agency in the playworld? 2. How do the children’s agentive actions change and develop over the spring? 3. What are the potentials and challenges of the playworld for promoting student agency? 4. How do the teachers and the children deal with the contradiction between control and agency in the playworld? The study consists of a summary part and four empirical articles which each have a particular viewpoint. Articles I and II deal with individual students’ paths to agency. In Article I the focus is on the role of resistance and questioning in enabling important spaces for agency. Article II takes a critical gender perspective and analyzes how two girls struggled towards recognition in the playworld. It also illuminates the role of imagination in developing a sense of agency. Article III examines how the open-ended and improvisational nature of the playworld interaction provided experiences and a sense of ‘shared agency’ for the students and teachers in the class. Article IV turns the focus on the teachers and analyzes how their role actions in the playworld helped the children to enact agency. It also discusses the challenges that the teachers faced in this work and asks what makes the playworld activity sustainable in the class. The summary part provides a critical literature review on the concept of agency and argues that the inherently contradictory nature of the phenomenon of agency has not been sufficiently theorized. The summary part also locates the playworld intervention in a historical frame by discussing the changing conceptions of adulthood and childhood in the West. By focusing on the changing role of play and art in both adults’ and children’s contemporary lives, the thesis opens up an important but often neglected perspective on the problem of promoting student agency in education. The results illustrate how engaging in a collectively imagined and dramatized pretend play space together with the children enabled the teachers to momentarily put aside their “knower” positions in the classroom. The fictive roles and the narrative plot helped them to create a necessary incompleteness and open-endedness in the activity that stimulated the children’s initiatives. This meant that the children too could momentarily step out of their traditional classroom positions as pupils and initiate action to further the collective play. Engaging in this kind of unconventional activity and taking up and enacting agency was, however, very challenging for the participating children and teachers. It often contradicted the need to sustain control and order in the classroom. The study concludes that play- and drama-based pedagogies offer a unique but undeveloped potential for developing educational spaces that help teachers and children deal with the often contradictory requirements of schooling.

Evaluation of driving ability of the disabled persons in the context of the psychological activity theory

In the future the number of the disabled drivers requiring a special evaluation of their driving ability will increase due to the ageing population, as well as the progress of adaptive technology. This places pressure on the development of the driving evaluation system. Despite quite intensive research there is still no consensus concerning what is the factual situation in a driver evaluation (methodology), which measures should be included in an evaluation (methods), and how an evaluation has to be carried out (practise). In order to find answers to these questions we carried out empirical studies, and simultaneously elaborated upon a conceptual model for driving and a driving evaluation. The findings of empirical studies can be condensed into the following points: 1) A driving ability defined by the on-road driving test is associated with different laboratory measures depending on the study groups. Faults in the laboratory tests predicted faults in the on-road driving test in the novice group, whereas slowness in the laboratory predicted driving faults in the experienced drivers group. 2) The Parkinson study clearly showed that even an experienced clinician cannot reliably accomplish an evaluation of a disabled person’s driving ability without collaboration with other specialists. 3) The main finding of the stroke study was that the use of a multidisciplinary team as a source of information harmonises the specialists’ evaluations. 4) The patient studies demonstrated that the disabled persons themselves, as well as their spouses, are as a rule not reliable evaluators. 5) From the safety point of view, perceptible operations with the control devices are not crucial, but correct mental actions which the driver carries out with the help of the control devices are of greatest importance. 6) Personality factors including higher-order needs and motives, attitudes and a degree of self-awareness, particularly a sense of illness, are decisive when evaluating a disabled person’s driving ability. Personality is also the main source of resources concerning compensations for lower-order physical deficiencies and restrictions. From work with the conceptual model we drew the following methodological conclusions: First, the driver has to be considered as a holistic subject of the activity, as a multilevel hierarchically organised system of an organism, a temperament, an individuality, and a personality where the personality is the leading subsystem from the standpoint of safety. Second, driving as a human form of a sociopractical activity, is also a hierarchically organised dynamic system. Third, in an evaluation of driving ability it is a question of matching these two hierarchically organised structures: a subject of an activity and a proper activity. Fourth, an evaluation has to be person centred but not disease-, function- or method centred. On the basis of our study a multidisciplinary team (practitioner, driving school teacher, psychologist, occupational therapist) is recommended for use in demanding driver evaluations. Primary in a driver’s evaluations is a coherent conceptual model while concrete methods of evaluations may vary. However, the on-road test must always be performed if possible.

A Journey in the Landscape of Sustainable School Development “A Journey in the Landscape of Sustainable School Development” is a story of the Sorrila School development process. This research deals with a school development project as a process, and as a part of international projects on Education for Sustainable Development, with ENSI (Environment and School Initiatives) being the most important. The main purpose of the study was to analyze the change process as a general phenomenon as well as the learning connected to it. The research describes the development period 2001–2008 at the Sorrila Primary school. The research questions are as follows: 1. What did pupils learn during the research and development period? 2. How did the coordinating teacher develop personally? 3. How were the ENSI targets and other closely linked projects reached? 4. What was the feedback from the pupils, their parents and other teachers at the school? 5. How did the developing process proceed in 2001–2008? The method used was integrating action research, which also had ethnographical elements. Narrative was the form of the data as well as the manner of reporting. The method as a whole was integrating, ethnographical action research as a story. The research data consisted mostly of Knowledge Forum notes written by the teacher-researcher. Knowledge Forum is an Internetbased collaborative knowledge-building programme. Pupils’, parents’ and other teachers’ feedback, newspaper articles and students’ writings complied the data, which consists of material from seven years. Sustainable development was the basis of the school improvement. The targets of the United Nations Decade of Education for Sustainable Development (2005–2014) were part of the development projects. According to the research results the school was seen as part of complex systems where manifold and interactive learning took place. The learning of pupils, teachers and the school as a community can be characterised socioculturally. The school was able to reach a level of collaborative transformative learning. As well as several concrete projects, such as Comenius school project, school development consisted of networking at many levels. Along with the projects and networking, the school was able to apply the pedagogy of connection, by carrying out integrative and cross-disciplinary themes and using various learning and teaching methods. International cooperation was a natural part of the work. A figure of Aunt Green, the role model of the teacher researcher, was an innovation which resembled a change agent. The other role of the teacherresearcher as a coordinator, was important for her own professional development. According to the results the change process, which relied on sustainable school development, led the school along a road of positive renewals. It was not a series of projects but an ongoing process. The objectives of the international projects were accomplished to a great extent during the research period. According to the principles of action research, the main results were put forward in order to help others to develop their schools. Frictions and problems as well as positive experiences and rejecting dualities were seen as change forces.

Opettajan ja vanhemman vuorovaikutus ja keskustelun kehykset koululaisen kehityskeskusteluissa

The aim of the study is to describe the consultation discussions between the teacher, parents and the student. The structure and the interaction of the conversation is in the focus of the study. The study explicates the organization of the interaction and orientation of the participants in the conversation. The study approaches conversation as a dynamic activity and studies it from the point of view of the participants. Assessment is one of the themes involved in the teacher-parent-student consultation discussions. Assessment as a duty of the school brings an institutional aspect in the conversation, but the ways it is implemented and expressed varies in the conversational situations. Participants communication and interaction in the situation influences the ways the consultation discussions are carried out. The framework of the study is based on the ethno methodological approach where a social situation and its meaning is seen negotiated by the participants. The interest of the study is to find out how the participants implement mutual understanding and how it can be observed in their interaction. Quantitatively, the interaction of the participants is described in the framework of the interaction analysis and linked to the socio-emotional and rational aspects of the interaction. The empirical part of the study consists of data collected with questionnaires and videotaped conversations. The main research problems of the study are, how the teachers and parents described the consultation discussions and how the interaction of the teacher, the parent and the student is organized during the conversation. The background of the study is linked to the previous studies concerning co-operation between the teacher and the parent and home-school relationship. This part of the study aims to enlighten how the consultation discussions are part of the co-operation in the school context. The questionnaires link the consultation discussions to the every day co-operation between the teacher and the family. Expectations and results described by the parents and teachers are analysed. Videotaped data is both analysed quantitatively based on interaction analysis and approached with the ethno methodological interpretation. The interest of my study is, how people participate in the situation of consultation discussion, how they orientate in it and influence the conversation. The analyses of the consultation discussions are based on the both quantitative interaction analysis and ethno methodological frame analysis. With the theoretical approach of my study I want to describe and enlighten the organization of the interaction and ways of orientation of the participants in consultation discussions. Keywords: consultation discussion, interaction, evaluation, orientation in the conversation, home-school cooperation, quantitative interaction analysis, frame analysis

Ongelmana yhteistyökyvyttömyys? : Teoreettisen ymmärryksen etsintää web-avusteiselle tiedontuottamisyhteistyölle

Tutkimuksessa analysoidaan teoriatasolla web-avusteisen tiedontuottamisyhteistyön kokeilutoiminnassa esiin tulleita ongelmia ja kootaan niiden viitoittamana teoriaperustaa tulevaisuuden työskentelytavalle, tietämyksen web-avusteiselle ryhmäprosessoinnille. Keskiössä on ihminen kognitiivisena tiedonkäsittelijänä ja elinikäisenä oppijana. Organisaatiossa vallitsevat toimintastrategiat, ryhmätyöskentelyn organisointi ja ryhmässä toteutuvat käytännöt muodostavat yksilön toimintaa ohjaavan sosiaalisen toimintaympäristön, joka säätelee yhteistyöprosessin onnistumista. Yhteistyötä tarkastellaan sosiaalisen tiedonkäsittelyn ryhmäilmiönä, jossa käsite yhteistyökyky kyseenalaistuu. Tuotetussa teoriaperustassa ihminen nähdään monitasoisten oppimishaasteiden ristitulessa. Koulutuksessa vallitseva absoluuttinen tietokäsitys on pystyttävä muuttamaan konstruktivistiseksi tietokäsitykseksi: yhteistä tietämystä ryhmänä tuotettaessa yksilöiden tietämys on rakennusaineena. Koulussa saatu sosiaalisen tiedonkäsittelyn malli, itsekeskeisen tiedonkäsittelyn malli, ei sovellu tietämyksen ryhmäprosessointiin. Malliin liittyviä oppeja on poisopittava samalla kun ryhmäjäsenenä on suunniteltava ja yhdessä opeteltava ryhmäkeskeisiä ja web-avusteisia tiedonkäsittelymalleja. Näin yhteistyöprosessissa toteutuu rinnakkain asiaoppimista ja toimintaoppimista. Näitä molempia on tarpeen tukea kehitettäessä uudenlaisia web-avusteisia työskentelymenetelmiä. Osassa I esitellään tutkimuksen kokemusperäisiä virikkeitä. Suhteellisen tietokäsityksen mukaisesti tämä tutkimus on kiinteästi kytkeytynyt tutkijan elinikäiseen oppimiseen ja tutkimus kuvataan tutkijan yksilöllisen tietämyksen prosessointina. Tutkimusaiheen löytymiseen johtaneet käytännön havainnot aloittavat sen takia raportoinnin. Erityisesti koulun sosiaalisen tiedonkäsittelyn organisointi on tarkastelun kohteena. Osassa II hahmotetaan tutkimusnäkökulmaa. Tutkimuskysymykset ovat lähinnä viitoittamassa tietämyksen etsintää. Tutkimusmenetelmä, kokeilutoiminnan analysointi, on saanut vahvasti vaikutteita toimintatutkimuksesta. Tutkimusasetelman perustana on toimintaan kytkeytyvä ihmiskäsitys. Kirjallisuuden avulla etsitään mahdollisia kytkeytymiä ihmisen käyttäytymisen ja sosiaalisen toiminnan organisoinnin välillä. Osa III kuvailee tutkimusaihetta koskevan ymmärryksen prosessointia. Esiymmärrys yhteistyöstä ja yhteistyökäsitteen määrittely mahdollistavat kokeilutoimintaan ryhtymisen. Uusi viestintämahdollisuus (www) nähdään yhteisessä tiedonkäsittelyssä apuvälineenä. Käytännön kokeilujaksot tarjoavat aineksia kognitiivisen tiedonkäsittelyn syvällisten periaatteiden löytymiselle. Inhimillinen toiminta ja sosiaalinen tiedonkäsittely saavat teoriatason analysoinnissa oppimiseen perustuvia tulkintoja. Osassa IV esitellään tutkimuksen tavoitteena ollutta teoriaperustaa tietämyksen web-avusteiselle ryhmäprosessoinnille. Teoriatiivistelmässä keskiöön nousee ihmisen kognitiivinen tiedonkäsittely sekä konstruktivistisen asiaoppimisen että selviytymispainotteisen toimintaoppimisen muodossa. Sosiaalinen toimintaympäristö nähdään osallisena kognitiivisessa tiedonkäsittelyssä ja selityksenä sille, että yhteinen tiedonkäsittely ei onnistu pelkästään tietoverkkoympäristössä vaan tarvitaan myös sosiaalisia tapaamisia. Kokeilutoiminnan opetuksia tuodaan esille yhteistyöprosessin keskeisten tapahtumien tarkastelussa. Tuotettua teoriaperustaa koetellaan tieteen kentällä vertailemalla sitä muiden tutkijoiden julkaisemiin käsityksiin. Tietoverkkoteknologian suhdetta inhimilliseen tiedonkäsittelyyn verrataan muualla saatuihin ja julkaistuihin käsityksiin.

"Olen enemmän alkanut pohtimaan ja sanomaan ääneen mitä ajattelen" : ammatillinen kehittyminen ja yhteisöllinen palaute päiväkodin työtiimeissä

I have more often thought over what I am thinking and also I have often told it to others - professional development and collegial feedback on kindergarten teams. The need for professional feedback surfaces year after year in enquiries made among staff members in the field of early childhood education. Because the pressure to be effective adds to the workload of the heads of kindergartens, there are few opportunities to give staff concrete feedback on a daily basis. Because peers are able to observe each other close at hand, their reciprocal feedback can compensate for that of the kindergarten head. In this study the practical training process of collegial feedback is studied and also the opportunities for feedback as a means of supporting professional development in the context of kindergarten. The development project involving the entire kindergarten community (N=21) was implemented in 2003-2004 through three developing cycles. The Johar´s Window , produced by Luft and Jung with the Model of Situational Leadership by Hersey and Blanchard, acted as a theoretical frame of reference. It has been used in this study both for its qualitative and its quantitative methods. The data were carried out through questions, interviews, diaries, written descriptions and monthly evaluations. The qualitative and quantitative methods were also used in analysing the data. The results showed that during the training process, the staff as a giver of feedback moved from the professional basic level to the professional maturity level. Their awareness of both their own and their peers´ know-how expanded from the initial state to the final state. It became evident that team size is the essential key element in the practise of giving feedback to team members. The team atmosphere and the commitment of the team members are in significant factors in the training of giving and receiving feedback. As a result of analyses, delivering feedback was grouped into three categories: developmental feedback, descriptive feedback and either supportive or destructive feedback. Receiving feedback was likewise groupped into three categories: aspiring to develop, unaccommodating and accepting. The ability to control feelings improved along with the skills of giving feedback; it was possible to analyse development through the professional development model represented in the theory of the study. The results showed that professional know-how of other kinds also developed during the process. Giving feedback among fellow workers enables team members to receive feedback everyday. Training to give feedback means examining a field of professional know-how and also formulating shared rules. The results of this study give support to previous studies that have emphasised practical training in natural circumstances. Keywords: feedback, professional development, learning at work

Yhteinen käsityö peruskoulun 7. luokalla : Opettajien kokemuksia yhteisen käsityön opetuksesta ja organisoinnista

Finnish education politics presume that basic education should be equal to all students. While organising craft education equality can be understood as similarity or as possibility to choose. The possibility to be able to choose whether textile or technical craft despite of one´s gender has been the aim of laws and curriculums already over 30 years. In practice it´s almost impossible to students to ignore feminine and masculine roles that go deep into our culture. Choosing craft has been divided by gender, which is the reason why possibility to choose has not been good enough to educationalists of equality. The latest guidelines for the National core curriculum for bacis education were issued in 2004. According to curriculum craft education consists parts of both technical and textile craft. All students should take part in both sectors of crafts. Furthermore, one can be given a possibility to consentrate his studies in whether textile or technical craft. The curriculum does not set the rules how the education should be organised, which means that it can be organised in many ways depending on city, school or teacher. Teachers and other specialists have contradictory feelings towards shared craft education, because traditional way to see craft in Finland is to separate textile craft from technical craft. Both crafts have some common features that are introduced in curriculum. Besides there is many equal things in craft theories that bind textile and technical craft to each other. The main purpose of this research was to find out, how shared craft education has been organised at the 7.th grade in Finnish comprehensive school, and which things affect in the settlements. Second goal was to describe and compare teachers´ experiences in teaching shared craft education. Third aim of this study was how shared craft has changed craft education. I collected the research material in May 2006 by interviewing both textile and technical craft teachers who teach shared craft. The material consists of fourteen theme interviews. In the analysis of the material I used theoretic bounded document analysis. According to the research there are three different ways to organise shared craft education: 50 50-arrangement, exchanging period and project week. In the schools that carried out 50 50-arrangement teaching was realised mainly in heterogenous groups. Principals had usual a lot of authorization on how to arrange craft education, which means that their views on equality, laws and curriculum affected in the settlemets more than teachers´ opinions. Teachers´ attitudes to shared craft were mainly positive. The changing of craft education can be divided in two parts: the aims and the containings of the curriculum have changed, as well as the meaning of the craft as core subject. Teachers have been forced to decrease the containings of both textile and technical crafts. Despite of eliminations both crafts still have comprehensive containings. Teachers decided what to teach by these argumets: Students should learn some basic things or produce a certain product. Usually teachers had also a lot of experience and special intrests in crafts. According to this research there is four significant meanings for shared craft education: 1) developing readiness for doing things, 2) developing skills of thinking, 3) delight of doing things and 4) teaching attitude.

Suhteessa kohteeseen ja suhteessa toisiin : Oppiminen ja vuorovaikutus opettajaopiskelijoiden suunnittelutapaamisessa

Objectives. In this research I analyzed the learning process of teacher students in a planning meeting using the expansive learning cycle and types of interaction approaches. In activity theory framework the expansive learning cycle has been applied widely in analyzing learning processes taking several years. However, few studies exist utilizing expansive cycles in analyzing short single meetings. In the activity theory framework talk and interaction have been analyzed using following types of interaction: coordination, cooperation and communication. In these studies single interaction situations have been analyzed, in which the status and power positions of participants has been very different. Interactions of self-directed teams, in which the participants are equal, have been examined very little. I am not aware of any studies, in which both learning actions of the expansive cycle and types of interaction by analyzing the same data would have been utilized. The aim of my study was to describe the process of collaborative innovative learning in a situation where the student group tries to accomplish a broad and ill-defined learning task. I aim to describe, how this planning process proceeds through different phases of learning actions of the expansive cycle. My goal is to understand and describe the transformations in the quality of interaction and transitions which are related to it. Another goal of this study is to specify the possible similarities and differences between expansive learning and types of interactions. Methods. Data of this study consisted of videotaped meetings, which were part of the study module for class teacher degree. The first meeting of the study module was chosen to be the primary research material. Five students were present in the group meeting. Transcription of the conversation was analyzed by classifying the turns of conversation following phases of the expansive cycle. After that the material was categorized again by using types of interaction. Results and conclusions. As a result of this study I was able to trace all the phases of the expansive cycle except one. Also, I was able to identify all interaction types. When I compared the two modes of analysis side by side I was able to find connecting main phases. Thus I was able to identify the interdependence between the two ways of analysis on a higher level, although I was not able to notice correlation on the level of individual phases. Based on this, I conclude that learning of the group was simultaneously specification and formulation of the object at the different phases of expansive learning and transformation of the quality of the interaction while searching for the common object.

Zebrafish as a model of Parkinson's disease

Parkinson’s disease (PD) is the second most common neurodegenerative disease among the elderly. Its etiology is unknown and no disease-modifying drugs are available. Thus, more information concerning its pathogenesis is needed. Among other genes, mutated PTEN-induced kinase 1 (PINK1) has been linked to early-onset and sporadic PD, but its mode of action is poorly understood. Most animal models of PD are based on the use of the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). MPTP is metabolized to MPP+ by monoamine oxidase B (MAO B) and causes cell death of dopaminergic neurons in the substantia nigra in mammals. Zebrafish has been a widely used model organism in developmental biology, but is now emerging as a model for human diseases due to its ideal combination of properties. Zebrafish are inexpensive and easy to maintain, develop rapidly, breed in large quantities producing transparent embryos, and are readily manipulated by various methods, particularly genetic ones. In addition, zebrafish are vertebrate animals and results derived from zebrafish may be more applicable to mammals than results from invertebrate genetic models such as Drosophila melanogaster and Caenorhabditis elegans. However, the similarity cannot be taken for granted. The aim of this study was to establish and test a PD model using larval zebrafish. The developing monoaminergic neuronal systems of larval zebrafish were investigated. We identified and classified 17 catecholaminergic and 9 serotonergic neuron populations in the zebrafish brain. A 3-dimensional atlas was created to facilitate future research. Only one gene encoding MAO was found in the zebrafish genome. Zebrafish MAO showed MAO A-type substrate specificity, but non-A-non-B inhibitor specificity. Distribution of MAO in larval and adult zebrafish brains was both diffuse and distinctly cellular. Inhibition of MAO during larval development led to markedly elevated 5-hydroxytryptamine (serotonin, 5-HT) levels, which decreased the locomotion of the fish. MPTP exposure caused a transient loss of cells in specific aminergic cell populations and decreased locomotion. MPTP-induced changes could be rescued by the MAO B inhibitor deprenyl, suggesting a role for MAO in MPTP toxicity. MPP+ affected only one catecholaminergic cell population; thus, the action of MPP+ was more selective than that of MPTP. The zebrafish PINK1 gene was cloned in zebrafish, and morpholino oligonucleotides were used to suppress its expression in larval zebrafish. The functional domains and expression pattern of zebrafish PINK1 resembled those of other vertebrates, suggesting that zebrafish is a feasible model for studying PINK1. Translation inhibition resulted in cell loss of the same catecholaminergic cell populations as MPTP and MPP+. Inactivation of PINK1 sensitized larval zebrafish to subefficacious doses of MPTP, causing a decrease in locomotion and cell loss in one dopaminergic cell population. Zebrafish appears to be a feasible model for studying PD, since its aminergic systems, mode of action of MPTP, and functions of PINK1 resemble those of mammalians. However, the functions of zebrafish MAO differ from the two forms of MAO found in mammals. Future studies using zebrafish PD models should utilize the advantages specific to zebrafish, such as the ability to execute large-scale genetic or drug screens.

The function of Bmps and Runx2 in normal tooth development and in the pathogenesis of cleidocranial dysplasia

The development of many embryonic organs is regulated by reciprocal and sequential epithelial-mesenchymal interactions. These interactions are mediated by conserved signaling pathways that are reiteratively used. Cleidocranial dysplasia (CCD) is a congenital syndrome where both bone and tooth development is affected. The syndrome is characterized by short stature, abnormal clavicles, general bone dysplasia, and supernumerary teeth. CCD is caused by mutations in RUNX2, a transcription factor that is a key regulator of osteoblast differentiation and bone formation. The first aim of this study was to analyse the expression of a family of key signal molecules, Bone morphogenetic protein (Bmp) at different stages of tooth development. Bmps have a variety of functions and they were originally discovered as signals inducing ectopic bone formation. We performed a comparative in situ hybridisation analysis of the mRNA expression of Bmp2-7 from initiation of tooth development to differentiation of dental hard tissues. The expression patterns indicated that the Bmps signal between the epithelial and mesenchymal tissues during initiation and morphogenesis of tooth development, as well as during the differentiation of odontoblasts and ameloblasts. Furthermore, they are also part of the signalling networks whereby the enamel knot regulates the patterning of tooth cusps. The second aim was to study the role of Runx2 during tooth development and thereby to gain better understanding of the pathogenesis of the tooth phenotype in CCD. We analysed the tooth phenotype of Runx2 knockout mice and examined the patterns and regulation of Runx2 gene expression.. The teeth of wild-type and Runx2 mutant mice were compared by several methods including in situ hybridisation, tissue culture, bead implantation experiments, and epithelial-mesenchymal recombination studies. Phenotypic analysis of Runx2 -/- mutant tooth development showed that teeth failed to advance beyond the bud stage. Runx2 expression was restricted to dental mesenchyme between the bud and early bell stages of tooth development and it was regulated by epithelial signals, in particular Fgfs. We searched for downstream targets of Runx2 by comparative in situ hybridisation analysis. The expression of Fgf3 was downregulated in the mesenchyme of Runx2 -/- teeth. Shh expression was absent from the enamel knot in the lower molars of Runx2 -/- and reduced in the upper molars. In conclusion, these studies showed that Runx2 regulates key epithelial-mesenchymal interactions that control advancing tooth morphogenesis and histodifferentiation of the epithelial enamel organ. In addition, in the upper molars of Runx2 mutants extra buddings occured at the palatal side of the tooth bud. We suggest that Runx2 acts as an inhibitor of successional tooth formation by preventing advancing development of the buds. Accordingly, we propose that RUNX2 haploinsuffiency in humans causes incomplete inhibition of successional tooth formation and as a result supernumerary teeth.

Young Men s Sexual Behaviour in Finland and Estonia : Opportunities for prevention of sexually transmitted infections

Background: The incidence of sexually transmitted infections (STIs) in most EU states has gradually increased and the rate of newly diagnosed HIV cases has doubled since 1999. STIs differ in their clinical features, prognosis and transmission dynamics, though they do share a common factor in their mode of transmission −that is, human behaviour. The evolvement of STI epidemiology involves a joint action of biological, epidemiological and societal factors. Of the more immediate factors, besides timely diagnosis and appropriate treatment, STI incidence is influenced by population patterns of sexual risk behaviour, particularly the number of sexual partners and the frequency of unprotected intercourse. Assessment of sexual behaviour, its sociodemographic determinants and time-trends are important in understanding the distribution and dynamic of STI epidemiology. Additionally, in the light of the basic structural determinants, such as increased level of migration, changes in gender dynamics and impacts from globalization, with its increasing alignment of values and beliefs, can reveal future challenges related to STI epidemiology. STI case surveillance together with surveillance on sexual behaviour can guide the identification of preventive strategies, assess their effectiveness and predict emerging trends. The objective of this study was to provide base line data on sexual risk behaviour, self-reported STIs and their patterns by sociodemographic factors as well as associations of sexual risk behaviour with substance use among young men in Finland and Estonia. In Finland national population based data on adult men s sexual behaviour is limited. The findings are discussed in the context of STI epidemiology as well as their possible implications for public health policies and prevention strategies. Materials and Methods: Data from three different cross-sectional population-based surveys conducted in Finland and Estonia, during 1998 2005, were used. Sexual behaviour- and health-related questions were incorporated in two surveys in Finland; the Health 2000, a large scale general health survey, focussed on young adults, and the Military health behavioural survey on military conscripts participating in the mandatory military training. Through research collaboration with Estonia, similar questions to the Finnish surveys were introduced to the second Estonian HIV/AIDS survey, which was targeted at young adults. All surveys applied mail-returned, anonymous, self-administered questionnaires with multiple choice formatted answers. Results: In Finland, differences in sexual behaviour between young men and women were minor. An age-stratified analysis revealed that the sex-related difference observed in the youngest age group (18 19 years) levelled off in the age group 20 24 and almost disappeared among those aged 25 29. Marital status was the most important sociodemographic correlate for sexual behaviour for both sexes, singles reporting higher numbers of lifetime-partners and condom use. This effect was stronger for women than for men. However, of those who had sex with casual partners, 15% were married or co-habiting, with no difference between male and female respondents. According to the Military health behavioural survey, young men s sexual risk behaviour in Finland did not markedly change over a period of time between 1998 and 2005. Approximately 30−40% of young men had had multiple sex partners (more than five) in their lifetime, over 20% reported having had multiple sex partners (at least three) over the past year and 50% did not use a condom in their last sexual intercourse. Some 10% of men reported accumulation of risk factors, i.e. having had both, multiple sex partners and not used a condom in their last intercourse, over the past year of the survey. When differences and similarities were viewed within Finland and Estonia, a clear sociodemographic patterning of sexual risk behaviour and self-reported STIs was found in Finland, but a somewhat less consistent trend in Estonia. Generally, both, alcohol and drug use were strong correlates for sexual risk behaviour and self-reported STIs in Finland and Estonia, having a greater effect on engagement with multiple sex partners rather than unprotected intercourse or self-reported STIs. In Finland alcohol use, relative to drug use, was a stronger predictor of sexual risk behaviour and self-reported STIs, while in Estonia drug use predicted sexual risk behaviour and self-reported STIs stronger than alcohol use. Conclusions: The study results point to the importance for prevention of sexual risk behaviour, particularly strategies that integrate sexual risk with alcohol and drug use risks. The results point to the need to focus further research on sexual behaviour and STIs among young people; on tracking trends among general population as well as applying in-depth research to identify and learn from vulnerable and high-risk population groups for STIs who are exposed to a combination of risk factors.

Palladin, a novel microfilament protein

Palladin is a novel actin microfilament associated protein, which together with myotilin and myopalladin forms a novel cytoskeletal IgC2 domain protein family. Whereas the expression of myotilin and myopalladin is limited mainly to striated muscle, palladin is widely expressed in both epithelial and mesenchymal tissues, including heart and the nervous system. Palladin has a complex genetic structure and it is expressed as several different sized and structured splice variants, which also display differences in their expression pattern and interactions. In muscle cells, all the family members localize to the sarcomeric Z-disc, and in non-muscle cells palladin also localizes to the stress-fiber-dense regions, lamellipodia, podosomes and focal adhesions. A common feature of this protein family is the binding to α-actinin, but other interactions are mostly unique to each member. Palladin has been shown to interact with several proteins, including VASP, profilin, Eps8, LASP-1 and LPP. Its domain structure, lack of enzymatic activity and multiple interactions define it as a molecular scaffolding protein, which links together proteins with different functional modalities into large complexes. Palladin has an important role in cytoskeletal regulation, particularly in stress fiber formation and stabilization. This assumption is supported by several experimental results. First, over-expression of palladin in non-muscle cells results in rapid reorganization of the actin cytoskeleton and formation of thick actin bundles. Second, the knock-down of palladin with anti-sense and siRNA techniques or knock-out by genetic methods leads to defective stress fiber formation. Furthermore, palladin is usually up-regulated in situations requiring a highly organized cytoskeleton, such as differentiation of dendritic cells, trophoblasts and myofibroblasts, and activation of astrocytes during glial scar formation. The protein family members have also direct disease linkages; myotilin missense mutations are the cause of LGMD1A and myofibrillar myopathy. Palladin mutations and polymorphisms, on the other hand, have been linked to hereditary pancreatic cancer and myocardial infarction, respectively. In this study we set out to characterize human palladin. We identified several palladin isoforms, studied their tissue distribution and sub-cellular localization. Four novel interaction partners were identified; ezrin, ArgBP2, SPIN90 and Src-kinase.The previously identified interaction between palladin and α-actinin was also characterized in detail. All the identified new binding partners are actin cytoskeleton associated proteins; ezrin links the plasma membrane to the cytoskeleton, ArgBP2 and SPIN90 localize, among other structures, to the lamellipodia and in cardiomyocytes to the Z-disc. Src is a transforming tyrosine kinase, which besides its role in oncogenesis has also important cytoskeletal associations. We also studied palladin in myofibroblasts, which are specialized cells involved in diverse physiological and pathological processes, such as wound healing and tissue fibrosis. We demonstrated that palladin is up-regulated during the differentiation of myofibroblasts in an isoform specific manner, and that this up-regulation is induced by TGF-β via activation of both the SMAD and MAPK signalling cascades. In summary, the results presented here describe the initial characterization of human palladin and offer a basis for further studies.

Latent TGF-β binding proteins -3 and -4 : transcriptional control and extracellular matrix targeting

Extracellular matrix (ECM) is a complex network of various proteins and proteoglycans which provides tissues with structural strength and resilience. By harvesting signaling molecules like growth factors ECM has the capacity to control cellular functions including proliferation, differentiation and cell survival. Latent transforming growth factor β (TGF-β) binding proteins (LTBPs) associate fibrillar structures of the ECM and mediate the efficient secretion and ECM deposition of latent TGF-β. The current work was conducted to determine the regulatory regions of LTBP-3 and -4 genes to gain insight into their tissue-specific expression which also has impact on TGF-β biology. Furthermore, the current research aimed at defining the ECM targeting of the N-terminal variants of LTBP-4 (LTBP-4S and -4L), which is required to understand their functions in tissues and to gain insight into conditions in which TGF-β is activated. To characterize the regulatory regions of LTBP-3 and -4 genes in silico and functional promoter analysis techniques were employed. It was found that the expression of LTBP-4S and -4L are under control of two independent promoters. This finding was in accordance with the observed expression patterns of LTBP-4S and -4L in human tissues. All promoter regions characterized in this study were TATAless, GC-rich and highly conserved between human and mouse species. Putative binding sites for Sp1 and GATA family of transcription factors were recognized in all of these regulatory regions. It is possible that these transcription factors control the basal expression of LTBP-3 and -4 genes. Smad binding element was found within the LTBP-3 and -4S promoter regions, but it was not present in LTBP-4L promoter. Although this element important for TGF-β signaling was present in LTBP-4S promoter, TGF-β did not induce its transcriptional activity. LTBP-3 promoter activity and mRNA expression instead were stimulated by TGF-β1 in osteosarcoma cells. It was found that the stimulatory effect of TGF-β was mediated by Smad and Erk MAPK signaling pathways. The current work explored the ECM targeting of LTBP-4S and identified binding partners of this protein. It was found that the N-terminal end of LTBP-4S possesses fibronectin (FN) binding sites which are critical for its ECM targeting. FN deficient fibroblasts incorporated LTBP-4S into their ECM only after addition of exogenous FN. Furthermore, LTBP-4S was found to have heparin binding regions, of which the C-terminal binding site mediated fibroblast adhesion. Soluble heparin prevented the ECM association of LTBP-4S in fibroblast cultures. In the current work it was observed that there are significant differences in the secretion, processing and ECM targeting of LTBP-4S and -4L. Interestingly, it was observed that most of the secreted LTBP-4L was associated with latent TGF-β1, whereas LTBP-4S was mainly secreted as a free form from CHO cells. This thesis provides information on transcriptional regulation of LTBP-3 and -4 genes, which is required for the deeper understanding of their tissue-specific functions. Further, the current work elucidates the structural variability of LTBPs, which appears to have impact on secretion and ECM targeting of TGF-β. These findings may advance understanding the abnormal activation of TGF-β which is associated with connective tissue disorders and cancer.
