The thesis aims to link the biolinguistic research program and the results of studies in comceptual combination from cognitive psychology. The thesis derives a theory of syntactic structure of noun and adjectival compounds from the Empty Lexicon Hypothesis. Two compound-forming operations are described: root-compounding and word-compounding. The aptness of theory is tested with finnish and greek compounds. From the syntactic theory semantic requirements for conceptual system are derived, especially requirements for handling morphosyntactic features. These requirements are compared to three formidable theories of conceptual combination: relation theory CARIN, Dual-Process theory and C3-theory. The claims of explanatory power of relational distributions of modifier in CARIN-theory ared discarded, as the method for sampling and building relational distributions is not reliable and the algorithmic instantiation of theory does not compute what it claims to compute. From relational theory there still remains results supporting existence of 'easy' relations for certain concepts. Dual-Process theory is found to provide results that cannot in theory be affected by linguistic system, but the basic idea of property compounds is kept. C3-theory is found to be not computationally realistic, but the basic results of diagnosticity and local properties (domains) of conceptual system are solid. The three conceptual combination models are rethought as a problem of finding the shortest route between the two concepts. The new basis for modeling is suggested to be bare conceptual landscape with morphosyntactiic or semantic features working as guidance and structural features of landscape basically unknown, but such as they react to features from linguistic system. Minimalistic principles to conceptual modeling are suggested.

Aims. The beginning point of this research was confusion between studies claiming, that children mature Metalinguistic to read at 6-7 of age, and the fact, that in Montessori playschools children easily start writing and reading at age 3 to 5. Aim was also find out how conception of slow Metalinguistic development has started, and if there is some evidence of phoneme awareness of reading of young children in the field of research of reading. Aim was also seek evidence of the sensitive period of reading as Montessori described it. The research also wanted to turn up, if phoneme awareness only develops in children, who work with graphemes and with reading, or could it be found in children, who do not. The mean was to research how the Montessori reading material supports child’s Metalinguistic development, when child begins learning to read. The research plans to represent knowledge about how young children learn to write and read. Methods. Research performed in ordinary kindergarten and in Montessori playschool in Espoo. In kindergarten observed six children, age 3-4, at eight grapheme-rhyme sessions from January to April 2007, and conducting a test based on Chaney’s (1992) study of phoneme awareness of young children. In Montessori kindergarten were observed 17 children about their phoneme awareness and reading competition from January 2007 to March 2008. Their developments in reading were also measured three times from 1.9.07 to 20.3.08 with classification constructed for this study, loosely based on Chall’s (1983) reading stages. The Montessori reading material was analyzed about the influence they have to a child’s Metalinguistic development. This was done based to theory and its concepts from the field of research of reading; phoneme awareness, morphological, syntactical and semantic consciousness. Results and conclusions. Research proved that children 3-5 have naturally developed phoneme awareness. In kindergarten and in Montessori playschool children between 2 and 4 could do phoneme synthesis, and in the latter they also could do phoneme segmentation of words. Montessori reading material guided children gradually, except to read, also to observe and absorb Metalinguistic knowledge. Children learned to write and read. At the last evaluating day almost 50 % of children write and read clauses or stories, and 82 % could read at least words. Children can develop Metalinguistic awareness, while using the Montessori materials for learning to write and read. To reach literacy is easy for children because of their phoneme awareness.

This study examined year seven students´ proactive coping, self-efficacy and social support seeking. Proactive coping was defined as a behaviour where obstacles are seen as a challenge. In proactive coping, individuals set goals, build up resources and regulate their behaviour to achieve the goals. Self-efficacy can be seen as people’s beliefs about their capabilities. Social support seeking was divided into instrumental support seeking and emotional support seeking. According to the theoretical frame of this study self-efficacy and social support seeking were seen as resources to proactive coping (Greenglass 2002). The participants were 445 year seven students (Mo= 13 years) from seven secondary schools. The data was collected in March-May 2008. The survey consisted 37 Likert-scaled items from the Proactive Coping Inventory and from the General Self-Efficacy Scale. The survey consisted of four scales: Proactive Coping, Instrumental Support Seeking, Emotional Support Seeking and General Self-Efficacy. The participants' age, gender and studying in specialist streams were asked as background information. As a result, most of the participants (62 % girls, 38 % boys) reported fairly strong proactive coping: they can see obstacles as a challenge and they set goals and regulate their behaviour to achieve the goals. Most of the participants reported that they seek instrumental and emotional support when having troubles. Girls reported more social support seeking than did boys and the mean difference was statistically significant. Most of the participants had fairly high sense of self-efficacy. However, 4 % of the participants reported that they don’t believe in their capabilities. Some of these participants reported that they neither use proactive coping nor seek informational or emotional support when having troubles. Proactive coping correlated positively with self-efficacy and with social support seeking. In this study self-efficacy and social support seeking explained 47 % of proactive coping. It was discussed that children’s high sense of self-efficacy and social relationships can act as protective factors in transition to secondary school. When supporting children’s self-efficacy and social relationships one also assists children’s proactive coping. Proactive coping can be seen to support children’s personal growth.

Working life is changing. The core of the change is change in the production and service concepts of organizations. Changes at work are connected to problems in the well-being of employees. To respond to this challenge, occupational health care must develop a course of action. A group of occupational health care units has developed new activity theory-based methods, the object of which is to change the service concept of occupational health care. The focus is on the changes and disturbances in work activity. My aim was to study this development from the perspective of knowledge management; to clarify directors'/ managers' conceptions of the content and object of their managerial work and the tensions included in these conceptions; to examine the learning process involved in these methods and to bring to light the problems, developmental needs and challenges during the implementation and consolidation phases of the process. This was a case study which included 10 occupational health care units using or being trained to use activity theory-based methods. My data consisted of interviews with directors/managers and recordings of the meetings; 20 directors/ managers are represented; I interviewed seven directors/ managers who represented four units. Directors'/ managers' conceptions of the content and object of managerial work were divided into eight categories of description, which I connected to the historical forms of organizations and types of management. Intuitive and rational management are historically older forms of management. The categories of description representing intuitive and rational management contained many internal tensions, i.e. they do not satisfy the demands of the environment. On the other hand, the categories of description which represented management by results and the control of the development process contained very few or no tensions at all; they are effective in the present environment of occupational health care. The learning process of activity theory-based methods has been expansive in nature. The occupational health care units studied are in different phases of the learning process, and these processes have been different. In three units the focus was on work development; in one unit the focus was on development of the service concept. The most central problems, challenges and developmental needs during the implementation phase were related to learning and spreading of methods inside one's own unit, and during the consolidation phase to working with partners.

Motivation has an important role in academic learning for learning is regulated by motivation. Further motivation is centrally manifested by goals. Goals reflect values and regulate individual s orientation and what they strive for. In spite of the central role of motivation in academic learning, discussions on post-graduate education has somewhat overlooked motivational processes and concentrated on the excellence of performance. The aim of this study was to investigate what kind of goals PhD students have and how they experience their role in their own scientific community. It was also purpose to study how these goals and experienced roles are in relation with study each other, context, possible intentions of quitting studies and prolongation of studies. Furthermore, the aim was to investigate how different postgraduates differ in terms of how they experience their learning environment. The data was collected with the From PhD students to academic experts survey (Pyhältö & Lonka, 2006) from four complementary domains: medicine, arts, psychology and education. The survey consisted of both likert-scaled items and open ended questions. The participants were 601 postgraduate students. The goals and the experienced role in scientific community were analysed in terms of qualitative content analysis. The relation between goals and experienced role and background variables were tested using ?² and the differences between different postgraduate groups using one way analysis of variances (ANOVA). The results indicated that postgraduates goals varied based on whether they brought up goals related to the product (outcome of the thesis process), the process (thesis process as whole) or both the product and the process. Product goals consisted of for example career qualification and better status as process goals consisted for example of learning and influencing ones own discipline. The experienced role of the postgraduates differed in terms of whether the conception was organised, unorganised or controversial. Both the goals and the experienced roles were in relation with study context and commitment to the studies. The different postgraduate groups also differed in terms of how they experienced their own learning environment.

The main goal of this study was to explore experiences induced by playing digital games (i.e. meaning of playing). In addition, the study aimed at structuring the larger entities of gaming experience. This was done by using theory-driven and data grounded approaches. Previously gaming experiences have not been explored as a whole. The consideration of gaming experiences on the basis of psychological theories and studies has also been rare. The secondary goal of this study was to clarify, whether the individual meanings of playing are connected with flow experience in an occasional gaming situation. Flow is an enjoyable experience and usually activities that induce flow are gladly repeated. Previously, flow has been proved to be an essential concept in the context of playing, but the relations between meanings of playing and flow have not been studied. The relations between gender and gaming experiences were examined throughout the study, as well as the relationship between gaming frequency and experiences. The study was divided into two sections, of which the first was composed according to the main goals. Its data was gathered by using an Internet questionnaire. The other section covered the themes that were formulated on the basis of the secondary aims. In that section, the participants played a driving game for 40 minutes and then filled in a questionnaire, which measured flow related experiences. In both sections, the participants were mainly young Finnish adults. All the participants in the second section (n = 60) had already participated in the first section (n = 267). Both qualitative and quantitative research techniques were used in the study. In the first section, freely described gaming experiences were classified according to the grounded theory. After that, the most common categories were further classified into the basic structures of gaming experience, some according to the existing theories of experience structure and some according to the data (i.e. grounded theory). In the other section flow constructs were measured and used as grouping variables in a cluster analysis. Three meaningful groups were compared regarding the meanings of gaming that were explored in the first section. The descriptions of gaming experiences were classified into four main categories, which were conceptions of the gaming process, emotions, motivations and focused attention. All the theory-driven categories were found in the data. This frame of reference can be utilized in future when reliability and validity of already existing methods for measuring gaming experiences are considered or new methods will be developed. The connection between the individual relevance of gaming and flow was minor. However, as the scope was specified to relations between primary meanings of playing and flow, it was noticed that attributing enjoyment to gaming did not lead to the strongest flow-experiences. This implies that the issue should be studied more in future. As a whole this study proves that gamer-related research from numerous vantage points can benefit from concentrating on gaming experiences.

Tutkimus tarkastelee opiskelijoiden kokemuksia opiskelun ohjauksesta etälukiossa. Etälukio on opetushallituksen syksyllä 1997 aloittama itseopiskeluväylä, jonka kautta voi suorittaa joko koko lukion oppimäärän tai yksittäisiäkursseja. Tutkimuksessa mielenkiinnon kohteena on ensinnäkin etälukiolaisten ohjauksen tarve ja heidän ohjauksensa toteutus. Ohjauksen toteutuksen tarkastelu jakaantuu kahteen osioon, kaksi-kolme kertaa kuussa järjestettävän lähiopetuksen tarkasteluun sekä faksin, kirjeen, puhelimen ja sähköpostin kautta tapahtuvan ohjauksen tarkasteluun. Keskeistä tutkimuksessa on myös opiskelijoiden ohjaukseen liittyvien kokemusten tarkastelu sekä se, millä tavoin ohjauksella on tuettu opiskelijoiden itsenäisten opiskeluvalmiuksien kehittymistä. Tutkimuksen teoriatausta jakaantuu kahteen osaan. Ensiksi analysoidaan etäopiskelun uusiin opiskeluympäristöihin keskeisesti liittyvää käsitettä avoin opiskeluympäristö, jonka määrittely on osoittautunut vaikeaksi. Toisen keskeisen osan teoriataustaa muodostaa ohjaus-käsitteen tarkastelu. Tutkimuksessa käytettiin kahta tiedonhankintamenetelmää. Kvantitatiiviseen kyselylomakkeeseen toukokuussa 1998 vastasi 115 opiskelijaa etälukion pilottialueilta Satakunnasta, Savosta ja Varsinais-Suomesta. Kyselylomakkeella hankittuja tietoja täydennettiin haastatteluilla joulukuussa 1998. Etälukiolaisten ohjauksen tarkastelu osoitti, että etälukio-opiskelu eroaa vain vähän muusta aikuislukio-opiskelusta. Suurimmalla osalla etälukiolaisista on tavoitteena ylioppilastutkinto, jonka sisällöt ja vaatimukset selkeästi rajoittavat yksilöllisyyden ja joustavuuden toteutumista etälukiossa. Etälukion opiskeluympäristön avoimuuden määrittely tarkemmin on jatkossa olennaisen tärkeätä. Tulokset osoittavat, että etälukiolaisten ohjaustarve oli ollut alhainen. Etälukion suorittaminen itsenäisesti osoittautui mahdolliseksi. Suurimman osan ohjauksesta opiskelijat olivat saaneet osallistumalla lähiopetukseen. Lähiopetus osoittautui luonteeltaan opettajajohtoiseksi ryhmäopetukseksi. Opiskelijat kokivat, että lähiopetukseen oleva aika on rajallinen, joten henkilökohtaisen ohjauksen pyytäminen lähiopetuksessa ei ollut ollut mahdollista. Opiskelijoista 40% oli hyödyntänyt lähiopetuksen lisäksi tarjottua ohjausta joko vain hyvin vähän tai ei lainkaan. Opiskelijoista yli puolet ei ollut käyttänyt sähköpostia lainkaan tai oli käyttänyt sitä vain harvemmin kuin kerran kuussa. Internetin ja sähköpostin käyttötaidoilla ei koettu olevan suurta merkitystä etälukio-opiskelussa. Opiskelijoiden ohjaukseen liittämät kokemukset olivat positiivisia. Tärkeintä opiskelijoille oli tieto siitä,että ohjausta oli tarvittaessa ollut saatavilla, vaikka sitä oli vain vähän hyödynnetty. Etälukiolaiset eivät kokeneet etälukio-opiskelun vaatineen uusien itsenäisten opiskelutaitojen oppimista.

The aim of this study was to investigate the connection between teachers' burn-out and professional development. In addition, the study aimed at clarifying teachers' conceptions of the significance of in-service training on work-related well-being. The theoretical starting points of the study were based on a model of burn-out (Kalimo & Toppinen1997) and a model of teachers' professional development (Niemi 1989). Present study can be seen as an independent follow-up study for a working ability project called "Uudistumisen eväät" that was followed through in Kuopio. The study was carried out in two phases. First, the connection between teachers' burn-out and professional development was charted with the help of a quantitative survey study. 131 teachers participated in the survey. Some of them were from schools that participated in the working ability project and the remainder were from other schools in Kuopio. The questionnaire consisted of self-constructed instruments of burn-out and professional development. According to the results, burn-out and professional development were strongly correlated with each other. Burn-out was summed up in three factors: emotional exhaustion, feelings of depersonalization and low feelings of personal accomplishment. Professional development was summed up in four factors: personality and pedagogical skills, learning-orientation, social skills and confronting change. Personality and pedagogical skills and skills of confronting change were correlated strongest with burn-out and its symptoms. A teacher, who has not found his/her own personal way of acting as a teacher and who considers change as something negative, is more likely to become exhausted than a teacher, who has developed his/her own pedagogical identity and who regards change more positively. In the second phase of this study, teachers' conceptions of the significance of in-service training on well-being was investigated with the help of group interviews (n=12). According to the results, the importance of in-service training was significant on the well-being of teachers. It appeared that in-service training promotes well-being by providing teachers with motivation, professional development and the possibility of taking a break from teaching and cooperating with other teachers. It has to be based on teachers' own needs. It has to be offered to teachers frequently and early enough. If teachers are already exhausted, they will neither have enough resources to participate in training, nor will they have the strength to make good use of it in practice. Both professional development and well-being are becoming more and more essential now that society is changing rapidly and the demands set on teachers are growing. Professional development can promote well-being, but are teachers too exhausted to develop themselves? Professional development demands resources and teachers may regard it as a threat and an additional strain. When the demands are so high that teachers cannot cope with them, they are likely to suffer stress and see reduction of commitment to their work and its development as a means to survive. If teachers stop caring about their work and their own development, how can we expect them to promote pupils' learning and development? It should be considered in the planning and implementation of in-service training and in arranging teachers' working conditions, that teachers have enough time and resources to develop themselves.

The aim of the study was to explore why the MuPSiNet project - a computer and network supported learning environment for the field of health care and social work - did not develop as expected. To grasp the problem some hypotheses were formulated. The hypotheses regarded the teachers' skills in and attitudes towards computing and their attitudes towards constructivist study methods. An online survey containing 48 items was performed. The survey targeted all the teachers within the field of health care and social work in the country, and it produced 461 responses that were analysed against the hypotheses. The reliability of the variables was tested using the Cronbach alpha coefficient and t-tests. Poor basic computing skills among the teachers combined with a vulnerable technical solution, and inadequate project management combined with lack of administrative models for transforming economic resources into manpower were the factors that turned out to play a decisive role in the project. Other important findings were that the teachers had rather poor skills and knowledge in computing, computer safety and computer supported instruction, and that these skills were significantly poorer among female teachers who were in majority in the sample. The fraction of teachers who were familiar with software for electronic patient records (EPR) was low. The attitudes towards constructivist teaching methods were positive, and further education seemed to utterly increase the teachers' readiness to use alternative teaching methods. The most important conclusions were the following: In order to integrate EPR software as a natural tool in teaching planning and documenting health care, it is crucial that the teachers have sufficient basic skills in computing and that more teachers have personal experience of using EPR software. In order for computer supported teaching to become accepted it is necessary to arrange with extensive further education for the teachers presently working, and for that further education to succeed it should be backed up locally among other things by sufficient support in matters concerning computer supported teaching. The attitudes towards computing showed significant gender differences. Based on the findings it is suggested that basic skills in computing should also include an awareness of data safety in relation to work in different kinds of computer networks, and that projects of this kind should be built up around a proper project organisation with sufficient resources. Suggestions concerning curricular development and further education are also presented. Conclusions concerning the research method were that reminders have a better effect, and that respondents tend to answer open-ended questions more verbosely in electronically distributed online surveys compared to traditional surveys. A method of utilising randomized passwords to guarantee respondent anonymity while maintaining sample control is presented.

Työuupumus on kolmitahoinen stressioireyhtymä, jolle on tyypillistä uupumusasteinen väsymys, kyynistyneisyys ja ammatillisen itsetunnon heikkeneminen. Balanssi-hanke perustettiin tutkimaan ja kehittämään ryhmähoitomuotoa vakavaan työuupumukseen. Projektin tavoitteena on selvittää kahden eri ryhmähoitomuodon vaikuttavuutta ja sellaisia yksilöön liittyviä tekijöitä, joilla saattaa olla vaikutusta ryhmähoidon tuloksellisuuteen. Tässä tutkimuksessa selvitettiin mielialan havainnoinnin, tunnistamisen ja säätelyn (Trait Meta-Mood) yhteyksiä työuupumuksen laskuun ryhmähoitojen aikana ja kuuden kuukauden pituisella seurantajaksolla. Emootioilla on useiden eri teorioiden mukaan yksilön sopeutumista edistävä signaalitehtävä. Mieliala kertoo yksilön sisäisestä tilasta, ja sitä voidaan kuvata miellyttävänä, epämiellyttävänä, kiihtyneenä tai rauhallisena. Mielialaa voi tarkastella mielialakokemuksen tai mielialan säätelyn tasolla. Mielialan säätelyn tasolla tarkoitetaan ajatuksia mielialasta. Tällä reflektiivisellä tasolla mielialaa havainnoidaan, tunnistetaan ja säädellään. Oletettiin, että jos mieliala tunnistetaan hyvin ja mielialaa säädellään tehokkaasti, työuupumus vähenee eli työuupumuksen ryhmähoito on tuloksellista. Lisäksi tutkittiin missä vaiheessa mahdolliset yhteydet ilmenevät ja eroavatko yhteydet psykoanalyyttisessä ja toiminnallisessa hoitoryhmässä. Tutkimusaineisto kerättiin 1999-2000. Koehenkilöt (n=99) olivat 31-59-vuotiaita valtion laitosten ja valtion yritysten työuupumuksesta kärsiviä työntekijöitä, miehiä oli 24 ja naisia 75. Lisäksi kerättiin ei-uupuneiden kontrolliryhmä (n = 26, ikä 37 - 58 vuotta), jota hyödynnettiin tässä tutkimuksessa vain uupuneiden ja ei-uupuneiden vertailuihin ennen hoidon alkua. Molempina vuosina uupuneet henkilöt satunnaistettiin toiminnallisiin ja psykoanalyyttisiin hoitoryhmiin. Työuupumus mitattiin 9 kuukautta kestäneen hoidon alussa, lopussa ja puoli vuotta hoidon päättymisen jälkeen. Mielialan havainnointi, tunnistaminen ja säätely mitattiin hoidon alussa, lopussa ja puoli vuotta hoidon päättymisen jälkeen. Tulokset osoittivat, että mielialan tunnistamisen korkea taso ja mielialan säätelyn korkea taso olivat yhteydessä työuupumuksen voimakkaampaan laskuun koko tutkimusjakson ajan. Yhteydet olivat erilaiset eri ryhmähoidoissa hoidon aikana ja seurantajaksolla. Hoidon aikana psykoanalyyttisessä hoitoryhmässä mielialan havainnoinnin lisääntyminen ja mielialan säätelyn tehokkuus olivat yhteydessä työuupumuksen voimakkaampaan laskuun. Toiminnallisessa hoitoryhmässä sen sijaan mielialan tunnistamisen taito oli yhteydessä työuupumuksen voimakkaampaan laskuun hoidon aikana. Seurantajaksolla molemmissa hoitoryhmissä mielialan tunnistamisen taito oli yhteydessä työuupumuksen voimakkaampaan laskuun. Kontrolliryhmässä ei todettu mielialan havainnoinnin, tunnistamisen ja säätelyn taitojen ja työuupumuksen vähenemisen välistä yhteyttä. Tutkimuksen tulokset antavat uutta tietoa sellaisista yksilöllisistä tekijöistä, joilla on työuupumuksen ryhmähoitoprosessia moderoiva rooli. Mielialan hyvin tunnistaminen ja mielialan tehokas säätely saattavat olla sellaisia ryhmäterapiassa opittuja yksilöllisiä voimavaroja, joita työuupumuksesta toipumisessa tarvitaan hoidon päättymisen jälkeen. Koska mielialan hyvin tunnistamisen, mielialan tehokkaan säätelyn ja työuupumuksen ryhmähoidon tuloksellisuuden väliset yhteydet todettiin molemmissa ryhmähoitomenetelmissä, voi olettaa, että molemmat ryhmähoitomenetelmät ovat vakavaa työuupumusta vähentäviä hoitomenetelmiä. Ryhmähoidon aikana opitut mielialan tunnistamisen ja säätelyn taidot auttavat ylläpitämään terapian aikana alkanutta hyvinvoinnin kasvua. Avainsanat: työuupumus, toiminnallinen ryhmäterapia, psykoanalyyttinen ryhmäterapia, mielialan havainnointi, mielialan tunnistaminen, mielialan säätely, työuupumuksen ryhmähoidon tuloksellisuus

The aim of this study was to build a model and analyze how users move in a virtual environment and to explore the experiential dimensions connected with different ways of moving. Due to the lack of previous research on this subject, this was an explorative study. This study also aimed to identify different ways how users move in virtual environments and the background variables connected to them. It was hypothesized that fluent movement in virtual environments is connected to high presence, skill and challenge assessments. Test participants (n = 68) were mostly highly educated young adults. A virtual environment was built using a CAVE -type virtual reality interface. The task was to search for objects that do not belong into a normal house. The participants movement in the virtual house was recorded on a computer. Movement was modelled using a cluster analysis of information entropy based movement measurements, acceleration, amount of stops and time spent being stationary. The experiential dimensions were measured using the EVEQ -questionnaire. We were able to identify four different ways of moving in virtual environments. In respect of background variables, the four groups differed only in the amount of weekly computer usage. However, fluent movement in virtual environments was connected to a high sense of presence. Furthermore, participants who moved fluently in the environment assessed their skills as being high and regarded the use of virtual environment as challenging. The results indicate that different ways of moving affects how people experience virtual environments. Consequently the participants assessment of their skills and level of challenge have an impact on the affective evaluation of the situation at hand. Entropy measures have not been previously applied when studying movement, and in addition the role of movement on the experiential dimensions of virtual environments is an unexplored subject. The movement analysis method introduced here is applicable to other research problems. Finally, this study expands on our knowledge of the special characteristics connected with the experiential dimensions of virtual environments.

Tutkimuksen tarkoituksena on selvittää, millaisia tiedonhakustrategioita tiedonhakijatkäyttävät etsiessään tietoa Internetistä. Käyttäjät luokitellaan kolmeen ryhmään tiedonhakustrategiansa mukaan. Haku-suuntautuneet käyttäjät käyttävät enimmäkseen hakukoneita, niin koko Internetin kattavia kuin sivustojen sisäisiäkin. Linkkisuuntautuneet taas joko tietävät tai arvaavat kohdesivuston osoitteen tai käyttävät laajoja hierarkkisia hakemistoja tiedon löytämiseen. He navigoivat mielummin sivustollakin linkkejä käyttäen eivätkä yleensä käytä hakutoimintoa. Eriytyneet käyttäjät eivät säännönmukaisesti suosi kumpaakaan tapaa, vaan valitsevat strategian tehtävän mukaan. Tietoa kerättiin kahdella tavalla: WWW-sivulla olleella kyselylomakkeella ja tiedonhakutestillä, jossa käyttäjille annettiin suoritettavaksi erilaisia tiedonhakutehtäviä. Tiedonhakutehtävät lajiteltiin kolmeen ryhmään sen mukaan, mitä strategiaa ne suosivat: hakustrategiaa suosivat, linkkistrategiaa suosivat ja neutraalit tehtävät. Tutkimusongelmana oli selvittää, kuinka tehtävän tyyppi ja ATK- ja Internet-kokemus vaikuttavat tiedonhakustrategian valintaan. Kävi ilmi, ettei käyttäjien suuntautuneisuus tiettyyn strategiaan vaikuta tiedonhakustrategian valintaan, vaan ainoastaan tehtävän tyyppi oli merkitsevä tekijä. Aikaisemman tutkimustiedon valossa kokeenet suosivat haku-suuntautunutta strategiaa. Tässä tutkimuksessa havaittiin, että kokemus lisäsi molempien strategioiden käyttöä yhtäläisesti, mutta tämä ilmiö oli havaittavissa ainoastaan kysely-lomakkeen pohjalta, ei testeissä. Molempien tiedonhakustrategioiden käyttö lisääntyy kokemuksen myötä, mutta suhteelliset osuudet pysyvät samoina. Syyksi sille, että kokeneet eivät suosineet hakustrategiaa, esitetään sitä, että tehtävät olivat liian helppoja, jolloin kokemus ei pääse auttamaan. Oleellisia eroja suoritusajoissa tai hakustrategian vaihdon tiheydessä ei havaittu suhteessa kokemukseen, ainoastaan suhteessa tehtävän tyyppiin.Tämäkin selitettiin toisentyyppisten tehtävien helppoudella. Tutkimuksessa pohditaan lisäksi asiantuntijuuden syntyä tiedonhakukontekstissa sekä esitetään metatietohypoteesi, jonka mukaan tiedonhakustrategian valintaan vaikuttaa tärkeänä tekijänä käyttäjän metatieto hakupalveluista. Metatietoon kuuluu tieto siitä, mitä hakukoneita on saatavilla, mitä tietoa verkosta kannattaa hakea, millä yrityksillä ja yhteisöillä on sisältörikkaat sivut jne, ja minkä tyyppistä tietoa yleensä on saatavilla. Kaikenkaikkiaan strategian valintaan esitetään taustalle kolmen tason tiedon vaikutusta: 1) oma asiantuntemus haettavasta alasta, 2) metatieto Internetin tiedonhakupalveluista sekä 3) tekninen tieto siitä, kuinka hakukoneet toimivat.

The study examined immigrants´ attitudes towards acculturation, in other words the social and cultural changes that take place in the adaptation process. The perspective of acculturation studies was also expanded by examining immigrants´ cultural values and their experiences of majority´s expectations. In addition, special interest was directed to the relations between acculturation attitudes and values and both factors´ relevance on psychological well-being. Indian born immigrants were selected as subjects as they are one of the fastest growing ethnic minorities in Finland. This minority has not been included in immigration studies previously. The seventy-five immigrants that participated as subjects represent a highly educated subgroup of Indian born immigrants. The study was carried out with posted questionnaires. Most of the subjects received an inquiry of their motivation to participate by e-mail or phone before the postal questionnaire. The results were in line with previous studies in Finland as the attitudes emphasising cultural integration were dominant. However, attitudes towards marriage, reflecting deeper and less flexible parts of culture, were dominated by separation motives. Immigrants´ perceptions of majority´s expectations reflected partly the real assimilation wishes demonstrated in previous studies. Against hypotheses, discrepancies between acculturation attitudes and experiences of majority´s expectations did not predict immigrants´ psychological well-being in a clear way. The highly educated Indian born immigrants emphasised self-direction and universalism in their values. This separates them from the traditional cultural values of India. The hypotheses made of the predictive relations between values and acculturation attitudes were partly confirmed. Also, the assumptions concerning both the stress buffering role of collectivistic values and the positive effect of achievement values on feelings of mastery were confirmed. Despite the limitations in the data, this study strengthens the view that cultural and personal values play a significant role in immigrants´ adaptation process. Information about values can benefit individuals making hard decisions and coping with cultural change as well as officials modifying Finnish immigration policy and planning the support system for immigrants.
