Retoriset keinot ja kirjoittajaroolit virolaisen Postimees-lehden ja suomalaisen Helsingin Sanomien verkkosivujen mielipidekeskusteluissa

Työssä tutkitaan erilaisin tekstintutkimuksen keinoin suomalaisen Helsingin Sanomat -lehden ja virolaisen Postimees-lehden internet-julkaisuissa ilmestyneisiin uutisiin liittyviä mielipidekirjoituksia. Työn tavoitteena on tarkastella eroja suomalaisten ja virolaisten kirjoittajien retoriikassa, argumentaatiossa ja roolivalinnoissa. Työn aineisto koostuu Helsingin Sanomien ja Postimees´in internet-sivuilla tammikuussa 2008 ilmestyneiden uutisten saamista mielipiteistä eli kommenteista. Molemmista lehdistä on valittu mukaan kymmenen uutista, jotka kaikki ovat saaneet keskimäärin 30 kommenttia. Uutiset ovat molemmissa maissa kotimaan uutisia ja ne on valittu satunnaisesti, joskin muutamien uutisten aiheet ovat lehdissä samankaltaisia. Työn neljännessä luvussa aineistoa analysoidaan rekisterien, tekstityyppien ja retoriikan näkökulmista. Rekistereistä puhuttaessa tarkoitetaan erilaisia tapoja kirjoittaa erilaisissa tilanteissa. Internetistä löytyvät mielipidekirjoitukset vaihtelevat virallisen kirjakielen ja arkisen puhekielen, jopa slangin, käytön välillä. Mielipidekirjoitukset kuuluvat argumentoivaan tekstityyppiin. Niiden tehtävä ei ole kertoa asioista neutraalisti, vaan kirjoittaja ilmaisee tekstissään omia arvojaan, mielipiteitään ja käsityksiään. Viidennessä luvussa aineistoa tutkitaan retorisen diskurssianalyysin keinoin, eli analysoidaan millaisia retorisia keinoja kirjoittajat käyttävät argumentaationsa vahvistamiseen. Retorisia keinoja esitellään työssä Arja Jokisen esittämän jaotuksen mukaisesti. Argumentaatiota voidaan jaotella myös sen mukaan, onko kyseessä hyökkäävä, puolustava, fakta- tai tunnepohjainen retoriikka. Kuudennessa luvussa analysoidaan mielipidekirjoitusten kohteita eli adressaatteja sekä kirjoittajien itselleen ottamia rooleja. Kirjoittajat voivat osoittaa roolivalintaansa useiden retoristen keinojen avulla. Rooleista yleisimmät ovat opettaja, asiantuntija ja kriitikko, marginaalisempia puolestaan kysyjä ja kannattaja/tukija. Aineiston analysointi on nostanut esille useita eroja suomalaisten ja virolaisten mielipidekirjoitusten välillä. Suomalaiset kirjoitukset kirjoitetaan usein yleis- tai kirjakielellä ja neutraalilla sävyllä. Virolaisissa mielipidekirjoituksissa on enemmän puhekielisyyttä ja kirjoitusvirheitä. Kirjoitusten sävy on jyrkempi ja arvoja tai arvioita välittävät sanat usein hyvin affektisia. Suomalaisissa mielipidekirjoituksissa kirjoittajat käyttävät argumentaationsa vahvistamiseen paljon oman asiantuntijuutensa korostamista tai vahvistamista konsensuksella, oma pätevyys myös perustellaan koulutuksen tai ammatin avulla. Suomalaisissa kirjoituksissa mielipiteet ovat myös pääasiassa faktoihin ja puolustavaan retoriikkaan perustuvia. Virolaisissa mielipiteissä kirjoittajat esittävät väitteensä tosiasioina ilman erityisiä perusteita. Argumentaatio rakentuu pääasiallisesti hyökkäävän ja tunnepohjaisen retoriikan päälle. Myös roolivalintojen välillä on eroja: suomalaismielipiteet esitetään useimmiten opettajan tai asiantuntijan roolista, virolaisissa mielipiteissä kirjoittaja on yleensä kriitikko tai asiantuntija.

Tundranenetsin todennäköisyysmoduksista ja niiden merkityksistä

Tundranenetsin kielessä on monimutkainen modusjärjestelmä, ja kielen kuvauksissa modusten määrä vaihtelee viidestä kahdeksaantoista. Tutkielmassani tarkastelen kielen tiettyjä verbimoduksia ja niiden merkityksiä. Tutkimukseni kohteena on seitsemän sellaista modusta, jotka aiemman kirjallisuuden mukaan ilmaisevat puhujan arviota kerrotun tapahtuman todennäköisyydestä eli episteemistä modaalisuutta. Työn tavoitteena on tarkastella modusten käyttöä ja esiintymisrajoituksia sekä muotojen merkityksiä. Aineistona käytän N. M. Tereštšenkon (1965) nenetsi-venäjä-suursanakirjan esimerkkilauseiden korpusta. Moduslauseiden merkityksiä tarkastelen teoreettisen nenetsin kielen taitoni sekä lauseiden leksikaalisen ja morfologisen analysoinnin sekä esimerkkilauseiden venäjännösten avulla. Modusten merkitysten tarkastelussa kiinnitän erityisesti huomiota toisaalta puhujan oman arvion ilmaisemiseen, episteemisyyteen, toisaalta puhujan tietolähteen ilmaisemiseen, evidentiaalisuuteen sekä näiden kahden merkityskategorian välisiin eroihin ja yhtäläisyyksiin. Tarkastelen myös modusten esiintymistä eri aspekti- ja tempusympäristöissä ja havainnoin modaalisten merkitysten lisäksi moduslauseiden temporaalisia ja aspektuaalisia merkityksiä. Työssäni totean probabilitatiiveiksi nimitettyjen modusten merkitykset inferentiaalisiksi tai harvemmin myös miratiivi-siksi. Inferentiaalisessa merkityksessä puhujan kertoma asia perustuu loogiseen päätelmään, joka tehdään muun tiedossa olevan asian perusteella. Miratiivisessa merkityksessä modusta käytetään kuvaamaan tapahtumaa, joka on puhujan näkökulmasta odotuksenvastainen tai yllättävä. Miratiivinen funktio on tulkintani mukaan ainoastaan varsinaisilla probabilitatiiveilla, ja niin kutsutut hyper- ja superprobabilitatiivi ilmaisevat inferentiaalisuutta eli ne korostavat puhujan tietolähdettä. Approksimatiiveiksi kutsutut kolme modusta ilmaisevat toisaalta kuvaannollisena, ei konkreettisesti tulkittavana kerrottavaa tapahtumaa. Toisaalta ne ilmaisevat puhujan subjektiivista arviota tilan tai tapahtuman toteutumis- tai voimassaolomahdollisuudesta. Modaalisen merkityksen lisäksi moduksilla on temporaalinen merkitys. Approksimatiivien ja probabilitatiivien ryhmissä on imperfektiiviseksi ja perfektiiviseksi kutsuttu modusmuoto. Imperfektiivisiksi kutsuttujen modusten temporaalinen merkitys vastaa aoristitempusta, joka lauseen aspektin mukaisesti viittaa joko juuri loppuun saatet-tuun tai nykyhetkessä tapahtuvaan. Lauseen aspekti on verbin aspektin mukaisesti hetkellinen tai jatkuva. Perfektiivisiksi kutsutut modukset viittaavat menneeseen aikaan. Perfektiivisen approksimatiivin status morfologisena moduksena voidaan aineistoni perusteella kyseenalaistaa. Menneeseen aikaan viitataan sen sijaan useammin imperfektiivisen approksimatiivin preterititempuksella. Probabilitatiivin ja preterititempuksen yhdistelmää ei aineistossani esiinny. Approksimatiivien ryhmässä on myös futuurinen variantti, joka viittaa yleensä tulevaan aikaan. Tulevaan viittaavat myös imperfektiivisen probabilitatiivin ja approksimatiivin muodot liittyessään johto-opillisen futuuritempukseen. Aineistoni modusesimerkit rajoittuvat usein yhden virkkeen kontekstiin, joten modusten merkitysten analysointi eri käyttöympäristöissä on työssäni vaikeaa. Vaikka onnistun hyvin hahmottelemaan tarkastelemien modusten keskeisimmät merkitysfunktiot aineistoni perusteella, tutkimuksen jatkaminen analyysin tarkentamiseksi on tarpeen.

Neutraalsus uudistekstides, kas seda on? : sukeldumissõda Eesti ja Soome pressis

Helsingin ja Tallinnan välillä liikennöinyt Copterlinen helikopteri putosi mereen 10.8.2005. Tarkastelen aiheen uutisointia Viron ja Suomen lehdistössä ja siitä mediapalstoilla käytyä “sotaa”. Tutkimuksen tavoitteena on selvittää minkälaisin keinoin mediasotaa käydään. Analysoin lähemmin yhden artikkelin Iltasanomista, Iltalehdestä, Turun Sanomista, Helsingin Sanomista ja Õhtuleht- ja Postimees-lehdistä. Teoreettisena pohjana käytän Norman Faircloughin teoksessa Language and Power esitettyä kriittistä diskurssianalyysiä. Käytän lisäksi mm. Tiit Hennosten kirjaa Uudise käsiraamat ja Reet Kasikin artikkeleita tekstianalyysistä. Mediasotaan osallistuvat laatulehdiksi luokiteltavat Turun Sanomat, Eesti Päevaleht, Postimees ja Turun Sanomat ja iltapäivälehdiksi luokiteltavat Iltalehti, Iltasanomat ja Õhtuleht. Helsingin Sanomat ei osallistunut mediasotaan, vaan keskittyy objektiiviseen uutisointiin. Keskeisin keino luoda sukellussota on vastakkainasettelu. Suhteet virolaisten ja suomalaisten välillä luodaan kansalaisuussanoilla suomalaiset ja virolaiset. Lukijoille kategorisoidaan maailma virolaiseksi ja suomalaiseksi. Positiivisia ja negatiivisia seikkoja asetetaan vastakkain luomalla tekstin sisäisiä antonyymipareja kuten nopea/ hidas, pieni ryhmä/ suuri ryhmä. Toimittajat luovat lähteilleen ja osallistujille auktoriteettia antamalla heille vastakkain matalan tai korkean statuksen kuten ministeri/ kadunmies. --- Suomalaiset lehdet käyttävät toimittajien itse keksimiä metaforia. Ekspressiivisiä sanoja käytetään välittämään tunteita, asenteita ja ajatuksia. Artikkeleissa hämärretään agentit kieliopin avulla. Käyttämällä passiivia, refleksiivisiä verbejä ja subjektittomia lauseita, esitetään prosesseja toisenlaisina kuin ne ovat ja jätetään näin aktiiviset tekijät mainitsematta. Artikkeleiden alku- ja loppulauseita vertaillessa voi havaita, että syytöksiä, spekulaatioita ja väitteitä esiintyy artikkeleiden otsikoissa ja ensimmäisissä lauseissa. Suomalaiset puolustautuvat huonojen pelastustyöntekijöiden leimaa vastaan ja virolaiset puolestaan oppipojan leimaa vastaan. Vasta-argumentteja tuodaan vain vähän ja ne sijoitetaan viimeisiksi. Molempien maiden lehdistöt kritisoivat viranomaisia. Artikkelit eivät noudata ideaaliuutisen kriteerejä.

Expert Identity in Development of Core-Task-Oriented Working Practices for Mastering Demanding Situations

The point of departure in this dissertation was the practical safety problem of unanticipated, unfamiliar events and unexpected changes in the environment, the demanding situations which the operators should take care of in the complex socio-technical systems. The aim of this thesis was to increase the understanding of demanding situations and of the resources for coping with these situations by presenting a new construct, a conceptual model called Expert Identity (ExId) as a way to open up new solutions to the problem of demanding situations and by testing the model in empirical studies on operator work. The premises of the Core-Task Analysis (CTA) framework were adopted as a starting point: core-task oriented working practices promote the system efficiency (incl. safety, productivity and well-being targets) and that should be supported. The negative effects of stress were summarised and the possible countermeasures related to the operators' personal resources such as experience, expertise, sense of control, conceptions of work and self etc. were considered. ExId was proposed as a way to bring emotional-energetic depth into the work analysis and to supplement CTA-based practical methods to discover development challenges and to contribute to the development of complex socio-technical systems. The potential of ExId to promote understanding of operator work was demonstrated in the context of the six empirical studies on operator work. Each of these studies had its own practical objectives within the corresponding quite broad focuses of the studies. The concluding research questions were: 1) Are the assumptions made in ExId on the basis of the different theories and previous studies supported by the empirical findings? 2) Does the ExId construct promote understanding of the operator work in empirical studies? 3) What are the strengths and weaknesses of the ExId construct? The layers and the assumptions of the development of expert identity appeared to gain evidence. The new conceptual model worked as a part of an analysis of different kinds of data, as a part of different methods used for different purposes, in different work contexts. The results showed that the operators had problems in taking care of the core task resulting from the discrepancy between the demands and resources (either personal or external). The changes of work, the difficulties in reaching the real content of work in the organisation and the limits of the practical means of support had complicated the problem and limited the possibilities of the development actions within the case organisations. Personal resources seemed to be sensitive to the changes, adaptation is taking place, but not deeply or quickly enough. Furthermore, the results showed several characteristics of the studied contexts that complicated the operators' possibilities to grow into or with the demands and to develop practices, expertise and expert identity matching the core task. They were: discontinuation of the work demands, discrepancy between conceptions of work held in the other parts of organisation, visions and the reality faced by the operators, emphasis on the individual efforts and situational solutions. The potential of ExId to open up new paths to solving the problem of the demanding situations and its ability to enable studies on practices in the field was considered in the discussion. The results were interpreted as promising enough to encourage the conduction of further studies on ExId. This dissertation proposes especially contribution to supporting the workers in recognising the changing demands and their possibilities for growing with them when aiming to support human performance in complex socio-technical systems, both in designing the systems and solving the existing problems.

Factors related to seat belt use : A Turkish case

Seat belts are effective safety devices used to protect car occupants from severe injuries and fatalities during road vehicle accidents. Despite the proven effectiveness of seat belts, seat belt use rates are quite low, especially in developing countries, such as Turkey. The general aim of the present study was to investigate a large variety of factors related to seat belt use among Turkish car occupants using different perspectives and methods and therefore, to contribute to the design of effective seat belt use interventions for increasing seat belt use rates in Turkey. Five sub-studies were conducted within the present study. In the first sub-study, environmental (e.g., road type) and psycho-social factors (e.g., belt use by other car occupants) related to the seat belt use of front-seat occupants were investigated using observation techniques. Being male, of a young age, and traveling on city roads were the main factors negatively related to seat belt use. Furthermore, seat belt use by the drivers and front-seat passengers was highly correlated and a significant predictors of each other. In the second sub-study, the motivations of the car occupants for seat belt use and non-use were investigated using interview techniques. Situational conditions, such as traveling on city roads and for short distances, and not believing in the effectiveness and relevance of seat belt use for safety, were the most frequently reported reasons for not using a seat belt. Safety, habit and avoiding punishment were among the most frequently reported reasons for using a seat belt. In the third sub-study, the Theory of Planned Behavior (TPB) and the Health Belief Model (HBM) were applied to seat belt use using Structural Equation Modeling techniques. The TPB model showed a good fit to the data, whereas the HBM showed a poor fit to the data. Within the TPB model, attitude and subjective norm were significant predictors of intentions to use a seat belt on both urban and rural roads. In the fourth sub-study, seat belt use frequency and motivations for seat belt use among taxi drivers were investigated and compared between free-time and work-time driving using a survey. The results showed that taxi drivers used seat belts more when driving a private car in their free-times compared to when driving a taxi during their work-times. The lack of a legal obligation to use a seat belt in city traffic and fear of being attacked or robbed by the passengers were found as two specific reasons for not using a seat belt when driving a taxi. Lastly, in the fifth sub-study, the relationship of seat belt use to driver and health behaviors was investigated using a survey. Although seat belt use was related both to health and driver behaviors, factor analysis results showed that it grouped with driver behaviors. Based on the results of the sub-studies, a tentative empirical model showing different predictors of seat belt use was proposed. According to the model, safety and normative motivations and perceived physical barriers related to seat belt use are the three important predictors of seat belt use. Keywords: Seat belt use; environmental factors; psycho-social factors; safety and normative motivations; the Theory of Planned Behavior; the Health Belief Model; health behaviors; driver behaviors; front-seat occupants; taxi drivers; Turkey.

Fatigued driving : prevalence, risk factors and groups, and the law

Fatigue and sleepiness are major causes of road traffic accidents. However, precise data is often lacking because a validated and reliable device for detecting the level of sleepiness (cf. the breathalyzer for alcohol levels) does not exist, nor does criteria for the unambiguous detection of fatigue/sleepiness as a contributing factor in accident causation. Therefore, identification of risk factors and groups might not always be easy. Furthermore, it is extremely difficult to incorporate fatigue in operationalized terms into either traffic or criminal law. The main aims of this thesis were to estimate the prevalence of fatigue problems while driving among the Finnish driving population, to explore how VALT multidisciplinary investigation teams, Finnish police, and courts recognize (and prosecute) fatigue in traffic, to identify risk factors and groups, and finally to explore the application of the Finnish Road Traffic Act (RTA), which explicitly forbids driving while tired in Article 63. Several different sources of data were used: a computerized database and the original folders of multidisciplinary teams investigating fatal accidents (VALT), the driver records database (AKE), prosecutor and court decisions, a survey of young male military conscripts, and a survey of a representative sample of the Finnish active driving population. The results show that 8-15% of fatal accidents during 1991-2001 were fatigue related, that every fifth Finnish driver has fallen asleep while driving at some point during his/her driving career, and that the Finnish police and courts punish on average one driver per day on the basis of fatigued driving (based on the data from the years 2004-2005). The main finding regarding risk factors and risk groups is that during the summer months, especially in the afternoon, the risk of falling asleep while driving is increased. Furthermore, the results indicate that those with a higher risk of falling asleep while driving are men in general, but especially young male drivers including military conscripts and the elderly during the afternoon hours and the summer in particular; professional drivers breaking the rules about duty and rest hours; and drivers with a tendency to fall asleep easily. A time-of-day pattern of sleep-related incidents was repeatedly found. It was found that VALT teams can be considered relatively reliable when assessing the role of fatigue and sleepiness in accident causation; thus, similar experts might be valuable in the court process as expert witnesses when fatigue or sleepiness are suspected to have a role in an accident’s origins. However, the application of Article 63 of the RTA that forbids, among other things, fatigued driving will continue to be an issue that deserves further attention. This should be done in the context of a needed attitude change towards driving while in a state of extreme tiredness (e.g., after being awake for more than 24 hours), which produces performance deterioration comparable to illegal intoxication (BAC around 0.1%). Regarding the well-known interactive effect of increased sleepiness and even small alcohol levels, the relatively high proportion (up to 14.5%) of Finnish drivers owning and using a breathalyzer raises some concern. This concern exists because these drivers are obviously more focused on not breaking the “magic” line of 0.05% BAC than being concerned about driving impairment, which might be much worse than they realize because of the interactive effects of increased sleepiness and even low alcohol consumption. In conclusion, there is no doubt that fatigue and sleepiness problems while driving are common among the Finnish driving population. While we wait for the invention of reliable devices for fatigue/sleepiness detection, we should invest more effort in raising public awareness about the dangerousness of fatigued driving and educate drivers about how to recognize and deal with fatigue and sleepiness when they ultimately occur.

Learning challenges of NGOs in development : Co-operation of Finnish NGOs in Morogoro, Tanzania

Non-governmental organisations (NGOs) have gained an important role in development co-operation during the last two decades. The development funding channelled through NGOs has increased and the number of NGOs engaged in development activities, both North and South, has been growing. Supporting NGOs has been seen as one way to strengthen civil society in the South and to provide potential for enhancing more effective development than the state, and to exercise participatory development and partnership in their North-South relationships. This study focuses on learning in the co-operation practices of small Finnish NGOs in Morogoro, Tanzania. Drawing on the cultural-historical activity theory and the theory of expansive learning, in this study I understand learning as a qualitative change in the actual co-operation practices. The qualitative change, for its part, emerges out of attempts to deal with the contradictions in the present activity. I use the concept of developmental contradiction in exploring the co-operation of the small Finnish NGOs with their Tanzanian counterparts. Developmental contradiction connects learning to actual practice and its historical development. By history, in this study I refer to multiple developmental trajectories, such as trajectories of individual participants, organisations, co-operation practices and the institutional system in which the NGO-development co-operation is embedded. In the empirical chapters I explore the co-operation both in the development co-operation projects and in micro-level interaction between partners taking place within the projects. I analyse the perceptions of the Finnish participants about the different developmental trajectories, the tensions, inclusions and exclusions in the evolving object of co-operation in one project, the construction of power relations in project meetings in three projects, and the collision of explicated partnership with the emerging practice of trusteeship in one project. On the basis of the empirical analyses I elaborate four developmental contradictions and learning challenges for the co-operation. The developmental contradictions include: 1) implementing a ready-made Finnish project idea vs. taking the current activities of Tanzanian NGO as a starting point; 2) gaining experiences and cultural interaction vs. access to outside funding; 3) promoting the official tools of development co-operation in training vs. use of tools and procedures taken from the prior activities of both partners in actual practice; and 4) asymmetric relations between the partners vs. rhetoric of equal partnership. Consequently, on the basis of developmental contradictions four learning challenges are suggested: a shift from legitimation of Finnish ideas to negotiation, transcending the separate objects and finding a partly joint object, developing locally shared tools for the co-operation, and identification and reflection of the power relations in the practice of co-operation.

Assessing organizational culture in complex sociotechnical systems : Methodological evidence from studies in nuclear power plant maintenance organizations

Failures in industrial organizations dealing with hazardous technologies can have widespread consequences for the safety of the workers and the general population. Psychology can have a major role in contributing to the safe and reliable operation of these technologies. Most current models of safety management in complex sociotechnical systems such as nuclear power plant maintenance are either non-contextual or based on an overly-rational image of an organization. Thus, they fail to grasp either the actual requirements of the work or the socially-constructed nature of the work in question. The general aim of the present study is to develop and test a methodology for contextual assessment of organizational culture in complex sociotechnical systems. This is done by demonstrating the findings that the application of the emerging methodology produces in the domain of maintenance of a nuclear power plant (NPP). The concepts of organizational culture and organizational core task (OCT) are operationalized and tested in the case studies. We argue that when the complexity of the work, technology and social environment is increased, the significance of the most implicit features of organizational culture as a means of coordinating the work and achieving safety and effectiveness of the activities also increases. For this reason a cultural perspective could provide additional insight into the problem of safety management. The present study aims to determine; (1) the elements of the organizational culture in complex sociotechnical systems; (2) the demands the maintenance task sets for the organizational culture; (3) how the current organizational culture at the case organizations supports the perception and fulfilment of the demands of the maintenance work; (4) the similarities and differences between the maintenance cultures at the case organizations, and (5) the necessary assessment of the organizational culture in complex sociotechnical systems. Three in-depth case studies were carried out at the maintenance units of three Nordic NPPs. The case studies employed an iterative and multimethod research strategy. The following methods were used: interviews, CULTURE-survey, seminars, document analysis and group work. Both cultural analysis and task modelling were carried out. The results indicate that organizational culture in complex sociotechnical systems can be characterised according to three qualitatively different elements: structure, internal integration and conceptions. All three of these elements of culture as well as their interrelations have to be considered in organizational assessments or important aspects of the organizational dynamics will be overlooked. On the basis of OCT modelling, the maintenance core task was defined as balancing between three critical demands: anticipating the condition of the plant and conducting preventive maintenance accordingly, reacting to unexpected technical faults and monitoring and reflecting on the effects of maintenance actions and the condition of the plant. The results indicate that safety was highly valued at all three plants, and in that sense they all had strong safety cultures. In other respects the cultural features were quite different, and thus the culturally-accepted means of maintaining high safety also differed. The handicraft nature of maintenance work was emphasised as a source of identity at the NPPs. Overall, the importance of safety was taken for granted, but the cultural norms concerning the appropriate means to guarantee it were little reflected. A sense of control, personal responsibility and organizational changes emerged as challenging issues at all the plants. The study shows that in complex sociotechnical systems it is both necessary and possible to analyse the safety and effectiveness of the organizational culture. Safety in complex sociotechnical systems cannot be understood or managed without understanding the demands of the organizational core task and managing the dynamics between the three elements of the organizational culture.

Exploring Problem Decomposition in Conceptual Design

Design embraces several disciplines dedicated to the production of artifacts and services. These disciplines are quite independent and only recently has psychological interest focused on them. Nowadays, the psychological theories of design, also called design cognition literature, describe the design process from the information processing viewpoint. These models co-exist with the normative standards of how designs should be crafted. In many places there are concrete discrepancies between these two in a way that resembles the differences between the actual and ideal decision-making. This study aimed to explore the possible difference related to problem decomposition. Decomposition is a standard component of human problem-solving models and is also included in the normative models of design. The idea of decomposition is to focus on a single aspect of the problem at a time. Despite its significance, the nature of decomposition in conceptual design is poorly understood and has only been preliminary investigated. This study addressed the status of decomposition in conceptual design of products using protocol analysis. Previous empirical investigations have argued that there are implicit and explicit decomposition, but have not provided a theoretical basis for these two. Therefore, the current research began by reviewing the problem solving and design literature and then composing a cognitive model of the solution search of conceptual design. The result is a synthetic view which describes recognition and decomposition as the basic schemata for conceptual design. A psychological experiment was conducted to explore decomposition. In the test, sixteen (N=16) senior students of mechanical engineering created concepts for two alternative tasks. The concurrent think-aloud method and protocol analysis were used to study decomposition. The results showed that despite the emphasis on decomposition in the formal education, only few designers (N=3) used decomposition explicitly and spontaneously in the presented tasks, although the designers in general applied a top-down control strategy. Instead, inferring from the use of structured strategies, the designers always relied on implicit decomposition. These results confirm the initial observations found in the literature, but they also suggest that decomposition should be investigated further. In the future, the benefits and possibilities of explicit decomposition should be considered along with the cognitive mechanisms behind decomposition. After that, the current results could be reinterpreted.

Kehittämisen kompastuskivet - myytit kehittämishankkeen keskusteluissa

I studied discussions during development project. Aim of the study was to analyse, what way workers represented their work: how normalized way of interpretation myths appeared in discourse and what consequences these utterances caused to drift of discussion. Change laboratory, which is a development method, is based to developmental work research methodology. Development is designed to be successful by learning activity and learning acts. Preventing factors of learning have been studied widely. Research has leaned to concept of resistance to change. Phenomenon of learning has been interpreted to be successful only if everybody has an agreement about the situation. There is also a new kind of concept of resistance. Resistance can be seen as a part of learning, normal processing of the learning activity. Another preventing factor can be seen as disorders of discourse, which are verbal ways of telling something that aren t real. Theoretically I consider these verbal ways as myth interpretations, which can be used as argumentative tools. I used analysis of discourse as an analytical method. Results of analysis revealed four different myth interpretations in workers discussions. Character of work was been described with myths unforeseen situations and disturbances are normal . Work was also described to be functional with myths system works and workers cause disturbances . Change laboratory discussions can be described as different social languages, which caused diverse perspectives to workers and researchers representations. Social languages also affected the way people analysed disturbances and system. Critical phase of change laboratory method seems to be analysis of disturbances and planning new mode of action. Myth utterances were used to reject ways of developing, analysis of system level and need of development. Myth utterances worked three different ways: ineffective, active or passive.

Montessorivälineet esiopetuksessa : Montessoriohjaajakoulutuksen saaneiden lastentarhanopettajien käsityksiä montessorivälineiden soveltuvuudesta esiopetuksessa

Tutkimuksessa selvitettiin montessorivälineiden soveltuvuutta suomalaiseen esiopetukseen montessoriohjaajakoulutuksen saaneiden lastentarhanopettajien arvioimina. Tutkimuksen ensimmäisenä tehtävänä oli selvittää, missä määrin montessorivälineitä käytettiin esiopetuksessa. Tutkimuksessa kartoitettiin montessorivälineiden osuutta vastaajien lapsiryhmien toimintamateriaaleista sekä mahdollisia esteitä niiden määrän lisäämiselle. Samoin selvitettiin, kuinka tärkeäksi montessorivälineiden merkitys koettiin opetussuunnitelman tavoitteiden toteutumisessa. Lisäksi kartoitettiin montessorivälineiden käytön laajuutta vastaajien työyhteisössä sekä mahdollisia esteitä välineiden laajemmalle käytölle. Tutkimuksen toisena tehtävänä oli selvittää, miten montessorivälineet tukevat lapsikeskeiselle esiopetukselle asetettuja tavoitteita yksilöllisyyden, sosiaalisten taitojen kehittymisen, omatoimisuuden ja aktiivisuuden, leikin merkityksen sekä välineistön monipuolisuuden suhteen. Tutkimuksen kohderyhmäksi valittiin mahdollisimman kattavasti ne montessoriohjaajat, jotka olivat saaneet myös lastentarhanopettajakoulutuksen. Kohderyhmä käsitti 74 henkilöä. Tutkimus suoritettiin postikyselynä joulukuussa 1996 ja tammikuussa 1997. Tutkimuksen vastausprosentiksi muodostui 79,3 %. Tutkimuksen tulokset osoittivat, että montessorivälineiden osuus vastaajien lapsiryhmien käytössä olevista toimintamateriaaleista oli merkittävä. Tämä korostui erityisesti montessoripäiväkodeissa, -leikkikouluissa ja päiväkodin montessoriryhmissä. Kaikissa toimipaikoissa montessorivälineitä ei ollut riittävästi, vaikka kiinnostus niitä kohtaan oli suuri. Montessorivälineiden osuuden lisäämistä vaikeuttivat mm. taloudelliset esteet. Montessorivälineiden merkitys opetussuunnitelman tavoitteiden toteutumisenkannalta osoittautui tärkeäksi. Tulosten perusteella suppeammallakin montessorivälinemäärällä oli opetussuunnitelman tavoitteiden kannalta suuri merkitys. Montessorivälineiden käytön laajuus vastaajientyöyhteisössä vaihteli toimipaikoittain. Koulutuksen puute ilmeni merkittävimmäksi esteeksi montessorivälineiden laajemmalle käytölle vastaajien työyhteisössä. Tutkimuksen tulosten perusteella montessorivälineillä työskentely tukee vahvasti lapsikeskeisen esiopetuksen kannalta tärkeitä tavoitteita yksilöllisyyden, omatoimisuuden ja aktiivisuuden sekä sosiaalisten taitojen kehittymisen suhteen. Montessorivälineiden katsottiin soveltuvan hyvin esiopetukseen myös monipuolisuutensa ansiosta. Leikin merkitys ei montessorivälineillä työskentelyssä ollut keskeisessä asemassa. Sen sijaan montessorivälineillä työskentelyssä painottuivat leikki, työ ja oppiminen.

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.

Aivojen jännitevasteiden rekisteröinti useaan äänen piirteeseen yhdellä mittauskerralla terveillä musiikkileikkikoulua käyvillä kaksivuotiailla

The early detection of hearing deficits is important to a child's development. However, examining small children with behavioural methods is often difficult. Research with ERPs (event-related potentials), recorded with EEG (electroencephalography), does not require attention or action from the child. Especially in children's ERP research, it is essential that the duration of a recording session is not too long. A new, faster optimum paradigm has been developed to record MMN (mismatch negativity), where ERPs to several sound features can be recorded in one recording session. This substantially shortens the time required for the experiment. So far, the new paradigm has been used in adult and school-aged children research. This study examines if MMN, LDN (late discriminative negativity) and P3a components can be recorded in two-year-olds with the new paradigm. The standard stimulus (p=0.50) was an 80 dB harmonic tone consisting of three harmonic frequencies (500 Hz, 1000 Hz and 1500 Hz) with a duration of 200 ms. The loudness deviants (p=0.067) were at a level of +6 dB or -6 dB compared to the standards. The frequency deviants (p=0.112) had a fundamental frequency of 550 or 454.4 Hz (small deviation), 625 or 400 Hz (medium deviation) or 750 or 333.3 Hz (large deviation). The duration deviants (p=0.112) had a duration of 175 ms (small deviation), 150 ms (medium deviation) or 100 ms (large deviation). The direction deviants (p=0.067) were presented from the left or right loudspeaker only. The gap deviant (p=0.067) included a 5-ms silent gap in the middle of the sound. Altogether 17 children participated in the experiment, of whom the data of 12 children was used in the analysis. ERP components were observed for all deviant types. The MMN was significant for duration and gap deviants. The LDN was significant for the large duration deviant and all other deviant types. No significant P3a was observed. These results indicate that the optimum paradigm can be used with two-year-olds. With this paradigm, data on several sound features can be recorded in a shorter time than with the previous paradigms used in ERP research.

Cloningerin psykobiologisen teorian temperamenttipiirteiden yhteys alkoholinkäyttöön nuorilla aikuisilla

The temperamental traits of Cloninger’s personality theory (novelty seeking, harm avoidance, reward dependence and persistence) reflect independent systems of central nervous system deciding responses toward new, rewarding and aversive stimuli. Thus, certain temperamental traits and their combinations may predispose to heavy drinking and alcohol dependence. Hence, the aim of the present study was to investigate associations between temperamental traits and the amount of alcohol consumption, frequency of heavy drinking and the maximum number of drinks per occasion. In this study, we investigated also whether these associations are only confounded by between-family differences in genetic and environmental factors. Furthermore the associations between temperamental trait combinations that reflect Cloninger's typology of alcoholism and alcohol use were studied. The subjects (n=401) in the current study were a group of FinnTwin16 study participators, Finnish twins born in 1974-79. Temperament was measured with TCI-R (Temperament and Character Inventory-Revised) a self-report form. The amount of alcohol consumption was asked by Semi-structured interview (Semi-Structured Assessment of Genetics of Alcoholism = SSAGA). The frequency of heavy drinking and maximum number of drinks per occasion were asked by mail form. In accordance with previous studies, novelty seeking had a positive relationship with the amount of alcohol consumption, frequency of heavy drinking and the maximum number of drinks per occasion in both genders. In this study, the association was proven independent of between-family differences in genetic and environmental factors that are associated to both novelty seeking and alcohol use. Surprisingly, reward dependence was negatively related to the maximum number of drinks per occasion in both genders. Persistence had a weak positive relationship with maximum number of drinks per occasion in men. The temperamental trait combinations that reflect Cloninger's typology of alcoholism did not differ from the other combinations in regard to alcohol use as hypothesized. The results confirm the previous finding about the relationship between novelty seeking and alcohol use. Support for Cloninger's typology of alcoholism in regard to combinations of temperamental trait was not achieved in this study.

Koko talo soi : Klemetti-Opisto suomalaisen musiikkikulttuurin kehittäjänä 1953-1968

This study aims to examine the operations and significance of the Klemetti Institute (Klemetti-Opisto) as a developer of Finnish music culture from 1953 to 1968 during the term of office of the Institute s founder and first director, Arvo Vainio. The Klemetti Institute was originally established as a choir institute, but soon expanded to offer a wide range of music courses. In addition to providing courses for choir leaders and singers, the Institute began its orchestral activities as early as the mid-1950s. Other courses included ear training seminars as well as courses for young people s music instructors and in playing the kantele (a Finnish string instrument) and solo singing. More than 20 types of courses were offered over the 16-year period. The Klemetti Institute s courses were incorporated into the folk high school courses offered by the Orivesi Institute (Oriveden Opisto) and were organised during the summer months of June and July. In addition to funding based on the Folk High School Act, financial assistance was obtained from various foundations and funds, such as the Wihuri Foundation. This study is linked to the context of historical research. I examine the Klemetti Institute s operations chronologically, classifying instruction into different course types, and analyse concert activities primarily in the section on the Institute s student union. The source material includes the Klemetti Institute archives, which consist of Arvo Vainio s correspondence, student applications, register books and cards, journals and student lists, course albums and nearly all issues of the Klemettiläinen bulletin. In addition, I have used focused interviews and essays to obtain extensive data from students and teachers. I concentrate on primary school teachers, who accounted for the majority of course participants. A total of more than 2,300 people participated in the courses, nearly half of whom took courses during at least two summers. Primary school teachers accounted for 50% to 70% of the participants in most courses and constituted an even larger share of participants in some courses, such as the music instructor course. The Klemetti Institute contributed to the expansion throughout Finland of a new ideal for choral tone. This involved delicate singing which strives for tonal purity and expressiveness. Chamber choirs had been virtually unheard of in Finland, but the Klemetti Institute Chamber Choir popularised them. Chamber choirs are characterised by an extensive singing repertoire ranging from the Middle Ages to the present. As the name suggests, chamber choirs were originally rather small mixed choirs. Delicate singing meant the avoidance of extensive vibrato techniques and strong, heavy forte sounds, which had previously been typical of Finnish choirs. Those opposing and shunning this new manner of singing called it ghost singing . The Klemetti Institute s teachers included Finland s most prominent pedagogues and artists. As the focused essays, or reminiscences as I call them, show, their significance for the students was central. I examine extensively the Klemetti Institute s enthusiastic atmosphere, which during the early years was characterised by what some writers described as a hunger for music . In addition to distributing a new tonal ideal and choir repertoire, the Klemetti Institute also distributed new methods of music education, thus affecting the music teaching of Finnish primary schools, in particular. The Orff approach, which included various instruments, became well known, although some of Orff s ideas, such as improvisation and physical exercise, were initially unfamiliar. More important than the Orff approach was the in-depth teaching at the Klemetti Institute of the Hungarian ear training method known as the Kodály method. Many course participants were among those launching specialist music classes in schools, and the method became the foundation for music teaching in many such schools. The Klemetti Institute was also a pioneer in organising orchestra camps for young people. The Klemetti Institute promoted Finnish music culture and played an important role in the continuing music education of primary school teachers.
