Toimitusjohtajavaihdokset ja muuttunut pankkityö - case: Savonlinnan Osuuspankki 1981 - 2001

Tutkielman tavoitteena oli tarkastella Savonlinnan Osuuspankissa toteutettuja muutoksia vuosina 1981 – 2001, ja sitä, miten henkilöstö on kokenut muutokset pankkityössä. Erityisesti tarkoitus oli tutkia, miten henkilöstö on kokenut toimitusjohtajavaihdokset. Tutkielma toteutettiin teoreettis-empiirisesti. Empiirinen osuus koottiin haastattelemalla kahdeksaa pankin työntekijää. Lisäksi apuna käytettiin pankista saatavaa kirjallista materiaalia. Kolmas osa empiriasta on tutkijan oma työhistoria pankissa ja tuona aikana tehdyt havainnot. Henkilöstö suhtautuu toimitusjohtajavaihdoksiin positiivisen odottavasti. Vahva sitoutuminen organisaatioon auttaa sopeutumaan jatkuviin muutoksiin. Muutosten tarpeellisuus ymmärretään paremmin ja niihin sitoudutaan, kun tietoa muutoksen tarpeellisuudesta saadaan riittävästi, ja kun henkilöstö pääsee osallistumaan muutoksen suunnitteluun. Muutosten ansiosta henkilöstö kokee usein myös oman osaamisensa ja uransa myönteisen kehittymisen

Managing the change of organizational culture in cross-border mergers and acquisitions: The role of post-acquisition integration in organizational culture change

Over the years, cross-border mergers and acquisitions have become a popular strategic option for variety of firms. Companies often seek rapid growth through acquiring potentially valuable enterprises or attempting to enhance their organization’s profitability by merging with other firms. However, managing the change of organizational culture is a major managerial challenge as companies often confront difficulties when merging two previously autonomous organizational cultures into one, joint organizational culture. Therefore, the purpose of this study is to increase understanding related to the challenges and possibilities concerning the management of organizational culture change in cross-border mergers and acquisitions. The research question “How to manage the change of organizational culture in cross-border mergers and acquisitions?” is analysed in relation to the theories presented in this thesis regarding organizational culture, organizational change and acculturation as well as in relation with the collected empirical data. The research question is divided into three sub-questions according to the following: (1) “What is the role of organizational culture in organizations?”, (2) “How to manage organizational change in mergers and acquisitions?” and (3) “How to manage organizational culture change through acculturation?”. The thesis is conducted as a qualitative case study research including three personal interviews and one group interview. The interviews were conducted as a combination of semi-structured and unstructured interviews. Theories related to organizational culture, the management of change as well as acculturation are studied and further analysed in relation to empirical material collected by the researcher. Research findings indicate that that several factors can influence the success of managing the organizational culture change in cross-border mergers and acquisitions. Factors such as defining the preferred acculturation model prior the merger; managing the resistance of change; open communication; acknowledgement of local culture and cultural differences; involvement of personnel in change processes; as well as the formulation and implementation of comprehensive change plans proved to be important factors with relation to successful management of organizational culture change

Change of Electricity Distribution Industry: Drivers and Opening Business Opportunities

As a result of the recent regulatory amendments and other development trends in the electricity distribution business, the sector is currently witnessing radical restructuring that will eventually impact the business logics of the sector. This report represents upcoming changes in the electricity distribution industry and concentrates on the factors that are expected to be the most fundamental ones. Electricity network companies nowadays struggle with legislative and regulatory requirements that focus on both the operational efficiency and the reliability of electricity distribution networks. The forces that have an impact on the distribution network companies can be put into three main categories that define the transformation at a general level. Those are: (1) a requirement for a more functional marketplace for energy, (2) environmental aspects (combating climate change etc.), and (3) a strongly emphasized requirement for the security of energy supply. The first point arises from the legislators’ attempt to increase competition in electricity retail markets, the second one concerns both environmental protection and human safety issues, and the third one indicates societies’ reduced willingness to accept interruptions in electricity supply. In the future, regulation of electricity distribution business may lower the threshold for building more weather-resistant networks, which in turn means increased underground cabling. This development pattern is reinforced by tightening safety and environmental regulations that ultimately make the overhead lines expensive to build and maintain. The changes will require new approaches particularly in network planning, construction, and maintenance. The concept for planning, constructing, and maintaining cable networks is necessary because the interdependencies between network operations are strong, in other words, the nature of the operation requires a linkage to other operations.

Innovations of ageing and societal transition : Dynamics of change of the socio-technical regime of ageing

The purpose of this dissertation is to examine the dynamics of the socio-technical system in the field of ageing. The study stems from the notion that the ageing of the population as a powerful megatrend has wide societal effects, and is not just a matter for the social and health sector. The central topic in the study is change: not only the age structures and structures of society are changing, but also at the same time there is constant development, for instance, in technologies, infrastructures and cultural perceptions. The changing concept of innovation has widened the understanding of innovations related to ageing from medical and assistive technological innovations to service and social innovations, as well as systemic innovations at different levels, which means the intertwined and co-evolutionary change in technologies, structures, services and thinking models. By the same token, the perceptions of older people and old age are becoming more multi-faceted: old age is no longer equated to illnesses and decline, but visions of active ageing and a third age have emerged, which are framed by choices, opportunities, resources and consumption in later life. The research task in this study is to open up the processes and mechanisms of change in the field of ageing, which are studied as a complex, multi-level and interrelated socio-technical system. The question is about co-effective elements consisting of macro-level landscape changes, the existing socio-technical regime (the rule system, practices and structures) and bottom-up niche-innovations. Societal transitions do not account for the things inside the regime alone, or for the long-term changes in the landscape, nor for the radical innovations, but for the interplay between all these levels. The research problem is studied through five research articles, which offer micro-level case studies to macro-level phenomenon. Each of the articles focus on different aspects related to ageing and change, and utilise various datasets. The framework of this study leans on the studies of socio-technical systems and multi-level perspective on transitions mainly developed by Frank Geels. Essential factors in transition from one socio-technological regime to another are the co-evolutionary processes between landscape changes, regime level and experimental niches. Landscape level changes, like the ageing of the population, destabilise the regime in the forms of coming pressures. This destabilization offers windows for opportunity to niche-innovations outside or at fringe of the regime, which, through their breakthrough, accelerate the transition process. However, the change is not easy because of various kinds of lock-ins and inertia, which tend to maintain the stability of the regime. In this dissertation, a constructionist approach of society is applied leaning mainly to the ideas of Anthony Giddens’ theory of structuration, with the dual nature of structures. The change is taking place in the interplay between actors and structures: structures shape people’s practices, but at the same time these practices constitute and reproduce social systems. Technology and other material aspects, as part of socio-technical systems, and the use of them, also take part in the structuration process. The findings of the study point out that co-evolutionary and co-effective relationships between economic, cultural, technological and institutional fields, as well as relationships between landscape changes, changes in the local and regime-level practices and rule systems, are a very complex and multi-level dynamic socio-technical phenomenon. At the landscape level of ageing, which creates the pressures and triggers to the regime change, there are three remarkable megatrends: demographic change, changes in the global economy and the development of technologies. These exert pressures to the socio-technical regime, which as a rule system is experiencing changes in the form of new markets and consumer habits, new ways of perceiving ageing, new models of organising the health care and other services and as new ways of considering innovation and innovativeness. There are also inner dynamics in the relationships between these aspects within the regime. These are interrelated and coconstructed: the prevailing perceptions of ageing and innovation, for instance, reflect the ageing policies, innovation policies, societal structures, organising models, technology and scientific discussion, and vice versa. Technology is part of the inner dynamics of the sociotechnological regime. Physical properties of the artefacts set limitations and opportunities with regard to their functions and uses. The use of and discussion about technology, contributes producing and reproducing the perceptions of old age. For societal transition, micro-level changes are also needed, in form of niche-innovations, for instance new services, organisational models or new technologies, Regimes, as stabilitystriven systems, tend to generate incremental innovations, but radically new innovations are generated in experimental niches protected from ‘normal’ market selection. The windows of opportunity for radical novelties may be opened if the circumstances are favourable for instance by tensions in the socio-technical regime affected by landscape level changes. This dissertation indicates that a change is taking place, firstly, in the dynamic interactionbetween levels, as a result of purposive action and governance to some extent. Breaking the inertia and using the window of opportunity for change and innovation offered by dynamics between levels, presupposes the actors’ special capabilities and actions such as dynamic capabilities and distance management. Secondly, the change is taking place the socio-technological negotiations inside the regime: interaction between technological and social, which is embodied in the use of technology. The use of technology includes small-level contextual scripts that also participate in forming broader societal scripts (for instance defining old age at the society level), which in their turn affect the formation of policies for innovation and ageing. Thirdly, the change is taking place by the means of active formation of the multi-actor innovation networks, where the role of distance management is crucial to facilitate the communication between actors coming from different backgrounds as well as to help the niches born outside the regime to utilise the window of opportunity offered by regime destabilisation. This dissertation has both theoretical and practical contributions. This study participates in the discussion of action-oriented view on transition by opening up of the socio-technological, coevolutionary processes of the multi-faceted phenomenon of ageing, which has lacked systematic analyses. The focus of this study, however, is not on the large-scale coordination and governance, but rather on opening up the incremental elements and structuration processes, which contribute to the transition little by little, and which can be affected to. This increases the practical importance of this dissertation, by highlighting the importance of very tiny, everyday elements in the change processes in the long run.

A year after Crimea: continuity and change of Finnish-Russian relations reflected in the views of the government officials of Finland and Russia

This thesis discusses the dynamism of bilateral relations between Finland and Russia and their interconnection with wider EU-Russia relations in the sight of the recent conflict in Ukraine. In particular, incorporation of Crimea in the territory of Russia in March 2014 is believed to have triggered a series of disputes between the European Union and Russia and thus, have impacted the course of the bilateral Finnish-Russian relations. The study leans on a premise that there are some historical traditions and regularities in the Finnish foreign policy course towards Russia which make the bilateral Finnish-Russian relations special. These traditions are distinguished and described in the book “Russia Forever? Towards Pragmatism in Finnish/Russian relations” (2008) edited by H. Rytövuori-Apunen. Assuming that the featured traditions take place in modern relations between Finland and Russia, the aim of the thesis is to find out how these traditions reappear during the year shaped by the events in Ukraine. In order to do that, author follows the timeline of happenings around the Ukraine crisis starting with Crimea’s referendum on independence, and exams the way these events were commented on and evaluated by the key government officials and political institutions of Finland and Russia. The main focus is given to the Finnish official discourse on Russia during the study period. The data collection, consisting of mostly primary sources (ministerial press releases and comments, statements, speeches and blog posts of individual policy makers) is processed using the thematic analysis supported by the content analysis. The study reveals that the consequences of the Ukraine crisis have brought, among others, complications to the economic cooperation between Finland and Russia, and have stimulated the increased attention of the Finnish decision makers to the country’s security questions. As a result, the character and importance of some historical regularities of the Finnish foreign policies on Russia, like the Continental Dilemma, have taken new shape.

Timing of Capacity Change: Models for Capital Intensive Industry

The suitable timing of capacity investments is a remarkable issue especially in capital intensive industries. Despite its importance, fairly few studies have been published on the topic. In the present study models for the timing of capacity change in capital intensive industry are developed. The study considers mainly the optimal timing of single capacity changes. The review of earlier research describes connections between cost, capacity and timing literature, and empirical examples are used to describe the starting point of the study and to test the developed models. The study includes four models, which describe the timing question from different perspectives. The first model, which minimizes unit costs, has been built for capacity expansion and replacement situations. It is shown that the optimal timing of an investment can be presented with the capacity and cost advantage ratios. After the unit cost minimization model the view is extended to the direction of profit maximization. The second model states that early investments are preferable if the change of fixed costs is small compared to the change of the contribution margin. The third model is a numerical discounted cash flow model, which emphasizes the roles of start-up time, capacity utilization rate and value of waiting as drivers of the profitable timing of a project. The last model expands the view from project level to company level and connects the flexibility of assets and cost structures to the timing problem. The main results of the research are the solutions of the models and analysis or simulations done with the models. The relevance and applicability of the results are verified by evaluating the logic of the models and by numerical cases.

Managing the Pricing of Integrated Solutions in Export Partnerships

Little research has been conducted to guide the management of marketing variables, such as pricing, in systems business context. Furthermore, given that international partnering has become a popular mode of operation for SMEs, the objective of the current thesis was to explore the scantly researched topic of managing the pricing of integrated solutions in an export partnership. Specifically, the thesis synthesizes literature findings from the three areas of export pricing, systems business, and export partnerships. The empirical section of the study consists of a qualitative single-case study of a Finnish systems integrator that has recently launched its export operations. Primary data was collected by conducting four interviews of the case company’s managers and by organizing one group interview session. The study findings indicate that a systems integrator’s pricing strategy in an export partnership can be very multidimensional and dependant on international pricing environment and partner characteristics, that an export partnership appears to have unique implications on a systems integrator’s pricing process, and that customer value –based pricing strategies might be particularly suited to pricing integrated solutions.

Evaluating the Maturity of Data Management Practices in a Major Energy Provider Company

Data is the most important asset of a company in the information age. Other assets, such as technology, facilities or products can be copied or reverse-engineered, employees can be brought over, but data remains unique to every company. As data management topics are slowly moving from unknown unknowns to known unknowns, tools to evaluate and manage data properly are developed and refined. Many projects are in progress today to develop various maturity models for evaluating information and data management practices. These maturity models come in many shapes and sizes: from short and concise ones meant for a quick assessment, to complex ones that call for an expert assessment by experienced consultants. In this paper several of them, made not only by external inter-organizational groups and authors, but also developed internally at a Major Energy Provider Company (MEPC) are juxtaposed and thoroughly analyzed. Apart from analyzing the available maturity models related to Data Management, this paper also selects the one with the most merit and describes and analyzes using it to perform a maturity assessment in MEPC. The utility of maturity models is two-fold: descriptive and prescriptive. Besides recording the current state of Data Management practices maturity by performing the assessments, this maturity model is also used to chart the way forward. Thus, after the current situation is presented, analysis and recommendations on how to improve it based on the definitions of higher levels of maturity are given. Generally, the main trend observed was the widening of the Data Management field to include more business and “soft” areas (as opposed to technical ones) and the change of focus towards business value of data, while assuming that the underlying IT systems for managing data are “ideal”, that is, left to the purely technical disciplines to design and maintain. This trend is not only present in Data Management but in other technological areas as well, where more and more attention is given to innovative use of technology, while acknowledging that the strategic importance of IT as such is diminishing.

Keskusteluja vuokratyöstä. Vuokratyön diskursiivinen rakentuminen Suomessa

1990-luvun alussa lainsäädäntö ja työmarkkinajärjestöt määrittelivät Suomessa, että vuokratyötä tuli käyttää vain tilapäiseen työvoimatarpeeseen, esimerkiksi sijaisuuksiin ja ruuhkahuippuihin. Joillakin aloilla vuokratyö oli työnantajien ja työntekijöiden yhteissopimuksella kielletty. Vaikka vuokratyösuhteet saivat jo 1980-luvulla niin Suomessa kuin kansainvälisestikin maineen työsuhdekeinotteluna, alkoi vuokratyön määrä Suomessa kasvaa 1990-luvun puolivälissä ja erityisesti tultaessa 2000-luvulle. Suomalaiset akateemiset tutkijat eivät ole juuri vuokratyöstä kiinnostuneet. Aiemmat, harvalukuiset tutkimukset ovat keskittyneet lähinnä työyhteisöjen ja työntekijöiden kokemuksiin sekä vuokratyön työehtoihin. Vuokratyö ymmärretäänkin edelleen lähinnä työntekijän subjektiivisena kokemuksena. Vuokratyössä on kuitenkin kysymys paitsi kokemuksista, myös yhteiskunnallisesta valtakamppailusta, jossa diskursiivisin keinoin pyritään vaikuttamaan ilmiöön nimeltä vuokratyö, laajemmin ilmiöön nimeltä työmarkkinat, sekä toisaalta kansalaisten käsityksiin työelämän ”normaalista”. Käsillä oleva tutkimus laajentaa ymmärrystä vuokratyöstä tarkastelemalla ilmiötä lainsäädännön, uutisoinnin ja markkinoinnin rakentamien julkisten käsitysten ja merkityksenantojen kautta. Teoreettisena viitekehyksenä käytän hallinnan ja työprosessin säätelyn teoriaperinteitä. Se, miten työmarkkinoiden muutosta ja uusia työsuhdemuotoja politiikassa, mediassa, lainsäädännössä, tai työpaikan kahvipöytäkeskusteluissa perustellaan ja tehdään ymmärrettäväksi, on samalla työelämään kiinnitettävien arvojen, merkitysten ja toimijuuksien luomista, rajaamista ja kuvailua. Työelämäpuheessa ei siis ole kyse vain talouden lainalaisuuksista, kansantalouden toimivuudesta, tai yritysten kilpailukyvystä, vaan myös ja erityisesti niiden toimijoiden luomisesta, määrittelemisestä ja legitimoimisesta, jotka työelämän kentällä saavat toimia ja tulevat palkituiksi. Säätelyn ja hallinnan näkökulmasta on relevanttia tarkastella millaisilla käsitteillä ja merkityksillä vuokratyötä ilmiönä rakennetaan . Tutkimuskysymyksinä esitän: 1) Miten ja millä perusteilla vuokratyöstä rakennettiin Suomessa legitiimi tapa työllistää ja työllistyä? 2) Millaisia työntekijäideaaleja vuokratyöhön liittyvissä keskusteluissa rakennetaan? Tutkimusaineistona tarkastelen lainsäädäntöön liittyviä dokumentteja, Helsingin Sanomien uutisointia, vuokratyöyritysten markkinointimateriaaleja, sekä vuokratyöyritysten edustajien haastatteluita. Analyysimenetelmänä käytän kriittistä diskurssianalyysia. Tämä menetelmä mahdollistaa puheen ja dokumenttien tarkastelun sosiaalisena toimintana, jolla eri toimijat pyrkivät osallistumaan yhteiskunnassa hyväksyttyjen ja tunnustettujen käsitysten ja toimintavaihtoehtojen rakentamis-, tulkinta- ja määrittelyprosesseihin. Tutkimukseni päätuloksena esitän, että vuokratyöstä muodostui legitiimi tapa työllistää Suomessa 1990-luvulla, koska vuokratyö käsitteellistettiin sekä lainsäädännön että median diskursseissa ennen kaikkea ratkaisuksi työttömyyteen. Toisaalta vuokratyö käsitteellistettiin vain marginaalisten työntekijäryhmien (naiset ja opiskelijat) rooliksi, jolloin se ei liittynyt miesvaltaisten työpaikkojen arkeen. Ratkaisuna työttömyyteen vuokratyö myös samalla luonnollistettiin osaksi yleisempää työmarkkinakehitystä, jolle ”kukaan ei voi mitään”. 2000-luvulla vuokratyö jatkoi voittokulkuaan ja rakentui pysyväksi ilmiöksi, koska työlainsäädännön uudistus institutionalisoi vuokratyön työehtosopimusmenettelyyn, jolloin sen ”salonkikelpoisuus” ja normaalius vahvistettiin. Vaikka työehtosopimusasia oli ratkaisuna merkittävä, nousi vuokratyön osalta itse työehtosopimus tärkeämmäksi kuin sen sisältö. Työehtosopimuksilla ei kuitenkaan pystytty vaikuttamaan esimerkiksi vuokratyöntekijän olemattomaan työsuhdeturvaan. Lisäksi työnantajapuhe käsitteellistää vuokratyön 2000-luvulla ennen kaikkea työmarkkinavaihtoehdoksi, vapautta ja monipuolisia työkokemuksia tarjoavaksi työmarkkinoiden katalysaattoriksi. Vuokratyö on tässä merkitysavaruudessa työntekijöille ”vain” yksi tapa työllistyä ja löytää oma tiensä työmarkkinoille, ei suinkaan työnantajien sanelema pakko. Työntekijöihin kohdistuva hallintapuhe niin mediassa kuin työnantajien haastatteluissakin pyrkii puolestaan rakentamaan ideaalityöntekijäkuvaksi yrittäjämäisen oman elämänsä toimitusjohtajan. Työnantajien diskursseissa kaikuvatkin työntekijään kohdistuva vaatimus itse itsensä ohjaamisesta sekä työntekijäidentiteetin muotoilemisesta joustavuutta, sopeutuvuutta, vaihtelua ja jatkuvaa muutosta vähintäänkin sietäväksi, mutta mieluiten näitä ominaisuuksia jopa aktiivisesti hakevaksi ja arvostavaksi. Työmarkkinoiden toimijana on nimenomaisesti yksilö, jonka mahdollisuudet menestyä ovat vain ja ainoastaan hänen omissa käsissään. Työntekijän roolin korostaminen aktiivisena toimijana ja vuokratyöstä ”oikeita”, norminmukaisia sisältöjä löytävänä pärjääjänä on diskursiivisesti hallittua yritystä ohjata työntekijöitä näkemään sekä itsensä tietynlaisina toimijoina että työmarkkinat tietyllä tavalla toimivina. Vuokratyössä ei ole kyse vain työntekijöiden yksilöllisistä tai yksittäisistä kokemuksista. Vuokratyö on yhteiskunnallisen merkityskamppailun tulos, jossa käyttövoimana ovat toimineet hallinnalliset ja säätelyyn pyrkivät käsitteellistykset työllisyydestä, yksilön valinnasta ja koko yhteiskunnan edusta. Hallinnan ja säätelyn näkökulmasta katsottuna vuokratyö on myös merkinnyt säätelyn liukumista tasa-arvoa, yhdenmukaista kohtelua ja työntekijän suojelua korostavasta viranomaisten ja poliittisten toimijoiden suorittamasta työmarkkinoiden kollektiivisesta säätelystä työnantajien ylläpitämään työntekijän persoonan ja käyttäytymisen hegemoniseen, yksilölliseen säätelyyn.

University students’ regulation of learning and text processing – examples from medical and teacher education

The general aim of the thesis was to study university students’ learning from the perspective of regulation of learning and text processing. The data were collected from the two academic disciplines of medical and teacher education, which share the features of highly scheduled study, a multidisciplinary character, a complex relationship between theory and practice and a professional nature. Contemporary information society poses new challenges for learning, as it is not possible to learn all the information needed in a profession during a study programme. Therefore, it is increasingly important to learn how to think and learn independently, how to recognise gaps in and update one’s knowledge and how to deal with the huge amount of constantly changing information. In other words, it is critical to regulate one’s learning and to process text effectively. The thesis comprises five sub-studies that employed cross-sectional, longitudinal and experimental designs and multiple methods, from surveys to eye tracking. Study I examined the connections between students’ study orientations and the ways they regulate their learning. In total, 410 second-, fourth- and sixth-year medical students from two Finnish medical schools participated in the study by completing a questionnaire measuring both general study orientations and regulation strategies. The students were generally deeply oriented towards their studies. However, they regulated their studying externally. Several interesting and theoretically reasonable connections between the variables were found. For instance, self-regulation was positively correlated with deep orientation and achievement orientation and was negatively correlated with non-commitment. However, external regulation was likewise positively correlated with deep orientation and achievement orientation but also with surface orientation and systematic orientation. It is argued that external regulation might function as an effective coping strategy in the cognitively loaded medical curriculum. Study II focused on medical students’ regulation of learning and their conceptions of the learning environment in an innovative medical course where traditional lectures were combined wth problem-based learning (PBL) group work. First-year medical and dental students (N = 153) completed a questionnaire assessing their regulation strategies of learning and views about the PBL group work. The results indicated that external regulation and self-regulation of the learning content were the most typical regulation strategies among the participants. In line with previous studies, self-regulation wasconnected with study success. Strictly organised PBL sessions were not considered as useful as lectures, although the students’ views of the teacher/tutor and the group were mainly positive. Therefore, developers of teaching methods are challenged to think of new solutions that facilitate reflection of one’s learning and that improve the development of self-regulation. In Study III, a person-centred approach to studying regulation strategies was employed, in contrast to the traditional variable-centred approach used in Study I and Study II. The aim of Study III was to identify different regulation strategy profiles among medical students (N = 162) across time and to examine to what extent these profiles predict study success in preclinical studies. Four regulation strategy profiles were identified, and connections with study success were found. Students with the lowest self-regulation and with an increasing lack of regulation performed worse than the other groups. As the person-centred approach enables us to individualise students with diverse regulation patterns, it could be used in supporting student learning and in facilitating the early diagnosis of learning difficulties. In Study IV, 91 student teachers participated in a pre-test/post-test design where they answered open-ended questions about a complex science concept both before and after reading either a traditional, expository science text or a refutational text that prompted the reader to change his/her beliefs according to scientific beliefs about the phenomenon. The student teachers completed a questionnaire concerning their regulation and processing strategies. The results showed that the students’ understanding improved after text reading intervention and that refutational text promoted understanding better than the traditional text. Additionally, regulation and processing strategies were found to be connected with understanding the science phenomenon. A weak trend showed that weaker learners would benefit more from the refutational text. It seems that learners with effective learning strategies are able to pick out the relevant content regardless of the text type, whereas weaker learners might benefit from refutational parts that contrast the most typical misconceptions with scientific views. The purpose of Study V was to use eye tracking to determine how third-year medical studets (n = 39) and internal medicine residents (n = 13) read and solve patient case texts. The results revealed differences between medical students and residents in processing patient case texts; compared to the students, the residents were more accurate in their diagnoses and processed the texts significantly faster and with a lower number of fixations. Different reading patterns were also found. The observed differences between medical students and residents in processing patient case texts could be used in medical education to model expert reasoning and to teach how a good medical text should be constructed. The main findings of the thesis indicate that even among very selected student populations, such as high-achieving medical students or student teachers, there seems to be a lot of variation in regulation strategies of learning and text processing. As these learning strategies are related to successful studying, students enter educational programmes with rather different chances of managing and achieving success. Further, the ways of engaging in learning seldom centre on a single strategy or approach; rather, students seem to combine several strategies to a certain degree. Sometimes, it can be a matter of perspective of which way of learning can be considered best; therefore, the reality of studying in higher education is often more complicated than the simplistic view of self-regulation as a good quality and external regulation as a harmful quality. The beginning of university studies may be stressful for many, as the gap between high school and university studies is huge and those strategies that were adequate during high school might not work as well in higher education. Therefore, it is important to map students’ learning strategies and to encourage them to engage in using high-quality learning strategies from the beginning. Instead of separate courses on learning skills, the integration of these skills into course contents should be considered. Furthermore, learning complex scientific phenomena could be facilitated by paying attention to high-quality learning materials and texts and other support from the learning environment also in the university. Eye tracking seems to have great potential in evaluating performance and growing diagnostic expertise in text processing, although more research using texts as stimulus is needed. Both medical and teacher education programmes and the professions themselves are challenging in terms of their multidisciplinary nature and increasing amounts of information and therefore require good lifelong learning skills during the study period and later in work life.

Isentropic Exergy and Pressure of the Shock Wave Caused by the Explosion of a Pressure Vessel

An accidental burst of a pressure vessel is an uncontrollable and explosion-like batch process. In this study it is called an explosion. The destructive effectof a pressure vessel explosion is relative to the amount of energy released in it. However, in the field of pressure vessel safety, a mutual understanding concerning the definition of explosion energy has not yet been achieved. In this study the definition of isentropic exergy is presented. Isentropic exergy is the greatest possible destructive energy which can be obtained from a pressure vessel explosion when its state changes in an isentropic way from the initial to the final state. Finally, after the change process, the gas has similar pressure and flow velocity as the environment. Isentropic exergy differs from common exergy inthat the process is assumed to be isentropic and the final gas temperature usually differs from the ambient temperature. The explosion process is so fast that there is no time for the significant heat exchange needed for the common exergy.Therefore an explosion is better characterized by isentropic exergy. Isentropicexergy is a characteristic of a pressure vessel and it is simple to calculate. Isentropic exergy can be defined also for any thermodynamic system, such as the shock wave system developing around an exploding pressure vessel. At the beginning of the explosion process the shock wave system has the same isentropic exergyas the pressure vessel. When the system expands to the environment, its isentropic exergy decreases because of the increase of entropy in the shock wave. The shock wave system contains the pressure vessel gas and a growing amount of ambient gas. The destructive effect of the shock wave on the ambient structures decreases when its distance from the starting point increases. This arises firstly from the fact that the shock wave system is distributed to a larger space. Secondly, the increase of entropy in the shock waves reduces the amount of isentropic exergy. Equations concerning the change of isentropic exergy in shock waves are derived. By means of isentropic exergy and the known flow theories, equations illustrating the pressure of the shock wave as a function of distance are derived. Amethod is proposed as an application of the equations. The method is applicablefor all shapes of pressure vessels in general use, such as spheres, cylinders and tubes. The results of this method are compared to measurements made by various researchers and to accident reports on pressure vessel explosions. The test measurements are found to be analogous with the proposed method and the findings in the accident reports are not controversial to it.

The effects of productivity on profitability: a case study at firm level using an activity-based costing approach

Productivity and profitability are important concepts and measures describing the performance and success of a firm. We know that increase in productivity decreases the costs per unit produced and leads to better profitability. This common knowledge is not, however, enough in the modern business environment. Productivity improvement is one means among others for increasing the profitability of actions. There are many means to increase productivity. The use of these means presupposes operative decisions and these decisions presuppose informationabout the effects of these means. Productivity improvement actions are in general made at floor level with machines, cells, activities and human beings. Profitability is most meaningful at the level of the whole firm. It has been very difficult or even impossible to analyze closely enough the economical aspects of thechanges at floor level with the traditional costing systems. New ideas in accounting have only recently brought in elements which make it possible to considerthese phenomena where they actually happen. The aim of this study is to supportthe selection of objects to productivity improvement, and to develop a method to analyze the effects of the productivity change in an activity on the profitability of a firm. A framework for systemizing the economical management of productivity improvement is developed in this study. This framework is a systematical way with two stages to analyze the effects of productivity improvement actions inan activity on the profitability of a firm. At the first stage of the framework, a simple selection method which is based on the worth, possibility and the necessity of the improvement actions in each activity is presented. This method is called Urgency Analysis. In the second stage it is analyzed how much a certain change of productivity in an activity affects the profitability of a firm. A theoretical calculation model with which it is possible to analyze the effects of a productivity improvement in monetary values is presented. On the basis of this theoretical model a tool is made for the analysis at the firm level. The usefulness of this framework was empirically tested with the data of the profit center of one medium size Finnish firm which operates in metal industry. It is expressedthat the framework provides valuable information about the economical effects of productivity improvement for supporting the management in their decision making.

Thick XML client and technology of its construction

Nykyään kolmeen kerrokseen perustuvat client-server –sovellukset ovat suuri kinnostuskohde sekä niiden kehittäjille etta käyttäjille. Tietotekniikan nopean kehityksen ansiosta näillä sovelluksilla on monipuolinen käyttö teollisuuden eri alueilla. Tällä hetkellä on olemassa paljon työkaluja client-server –sovellusten kehittämiseen, jotka myös tyydyttävät asiakkaiden asettamia vaatimuksia. Nämä työkalut eivät kuitenkaan mahdollista joustavaa toimintaa graafisen käyttöliittyman kanssa. Tämä diplomityö käsittelee client-server –sovellusten kehittamistä XML –kielen avulla. Tämä lähestymistapa mahdollistaa client-server –sovellusten rakentamista niin, että niiden graafinen käyttöliittymä ja ulkonäkö olisivat helposti muokattavissa ilman ohjelman ytimen uudelleenkääntämistä. Diplomityö koostuu kahdesta ostasta: teoreettisesta ja käytännöllisestä. Teoreettinen osa antaa yleisen tiedon client-server –arkkitehtuurista ja kuvailee ohjelmistotekniikan pääkohdat. Käytannöllinen osa esittää tulokset, client-server –sovellusten kehittämisteknologian kehittämislähestymistavan XML: ää käyttäen ja tuloksiin johtavat usecase– ja sekvenssidiagrammit. Käytännöllinen osa myos sisältää esimerkit toteutetuista XML-struktuureista, jotka kuvaavat client –sovellusten kuvaruutukaavakkeiden esintymisen ja serverikyselykaaviot.
