The objective of this thesis is to examine the factors that have an impact on the location decision of new manufacturing site and to create the relative order of importance of these factors by analytic hierarchy process (AHP). The decision making process especially related to the location selection and the measurement of the location factors are also examined. In theoretical part the character of decision making process and the relevant methods are introduced. Based on the previous studies of other researchers, the location factors are examined and the main research method, analytic hierarchy process, is also introduced. The empirical part of the study mainly follows the phases of decision making process and is emphasized on the main stages of analytic hierarchy process; building the hierarchy, defining the priorities and analyzing the results. The hierarchy is constructed from seven main criteria which all have several sub criteria. The evaluation of the hierarchy is implemented at the group decision making –laboratory and there can be seen significant differences between the importance of criteria. The final stage in the study is to create the appropriate measurement scales to the chosen criteria.

Hajautetuissa organisaatioissa määräaikainen tai pysyvä joukko ihmisiä työskentelee toisistaan erillään yhteisen tavoitteen saavuttamiseksi käyttäen apunaan tieto- ja viestintäteknologiaa. Tämän työn tavoitteena on tarkastella, minkälaisia hajautetun työn hallinnan hyviä käytäntöjä on olemassa. Lisäksi työn toisena tavoitteena on tutkia, miten hajautetun työn kustannukset eroavat perinteisen työn kustannuksista. Työn kohdeyrityksenä toimii IT-palveluyhtiö, jossa hajautettua työskentelytapaa on hyödynnetty jo jonkin aikaa. Työn teoriaosuudessa on käsitelty hajautetun työn sekä toimintolaskennan periaatteet. Näitä teoriaosuudessa käsiteltyjä asioita on sovellettu työn empiriaosuuden www-kyselyssä, joka liittyy hajautettuun työhön ja hajautetun työn hallinnan hyviin käytäntöihin, sekä kustannusrakennemallissa, jonka avulla hajautetun ja perinteisen työskentelytavan kustannusrakenteet on mallinnettu toimintolaskennan keinoin. Työn kohdeyrityksen työntekijät ovat kokeneet työyhteisönsä jonkin verran hajautuneiksi. Hajautetun työn haasteet ovat näkyneet hajautetun työn etuja enemmän työn kohdeyrityksessä sekä työntekijöiden päivittäisessä työskentelyssä. Työssä käsitellyistä hajautetun työn hallinnan hyvistä käytännöistä yli puolta on hyödynnetty kohdeyrityksessä melko paljon ja muutamaa käytäntöä on hyödynnetty vähemmän. Työssä toteutetun kustannusrakennemallin perusteella voidaan todeta, että hajautetulla työskentelytavalla on mahdollista saavuttaa noin 12 %:n kustannusetu perinteiseen työskentelytapaan verrattuna.

Credit risk assessment is an integral part of banking. Credit risk means that the return will not materialise in case the customer fails to fulfil its obligations. Thus a key component of banking is setting acceptance criteria for granting loans. Theoretical part of the study focuses on key components of credit assessment methods of Banks in the literature when extending credits to large corporations. Main component is Basel II Accord, which sets regulatory requirement for credit risk assessment methods of banks. Empirical part comprises, as primary source, analysis of major Nordic banks’ annual reports and risk management reports. As secondary source complimentary interviews were carried out with senior credit risk assessment personnel. The findings indicate that all major Nordic banks are using combination of quantitative and qualitative information in credit risk assessment model when extending credits to large corporations. The relative input of qualitative information depends on the selected approach to the credit rating, i.e. point-in-time or through-the-cycle.

In the present dissertation, multilingual thesauri were approached as cultural products and the focus was twofold: On the empirical level the focus was placed on the translatability of certain British-English social science indexing terms into the Finnish language and culture at a concept, a term and an indexing term level. On the theoretical level the focus was placed on the aim of translation and on the concept of equivalence. In accordance with modern communicative and dynamic translation theories the interest was on the human dimension. The study is qualitative. In this study, equivalence was understood in a similar way to how dynamic, functional equivalence is commonly understood in translation studies. Translating was seen as a decision-making process, where a translator often has different kinds of possibilities to choose in order to fulfil the function of the translation. Accordingly, and as a starting point for the construction of the empirical part, the function of the source text was considered to be the same or similar to the function of the target text, that is, a functional thesaurus both in source and target context. Further, the study approached the challenges of multilingual thesaurus construction from the perspectives of semantics and pragmatics. In semantic analysis the focus was on what the words conventionally mean and in pragmatics on the ‘invisible’ meaning - or how we recognise what is meant even when it is not actually said (or written). Languages and ideas expressed by languages are created mainly in accordance with expressional needs of the surrounding culture and thesauri were considered to reflect several subcultures and consequently the discourses which represent them. The research material consisted of different kinds of potential discourses: dictionaries, database records, and thesauri, Finnish versus British social science researches, Finnish versus British indexers, simulated indexing tasks with five articles and Finnish versus British thesaurus constructors. In practice, the professional background of the two last mentioned groups was rather similar. It became even more clear that all the material types had their own characteristics, although naturally not entirely separate from each other. It is further noteworthy that the different types and origins of research material were not used to represent true comparison pairs, and that the aim of triangulation of methods and material was to gain a holistic view. The general research questions were: 1. Can differences be found between Finnish and British discourses regarding family roles as thesaurus terms, and if so, what kinds of differences and which are the implications for multilingual thesaurus construction? 2. What is the pragmatic indexing term equivalence? The first question studied how the same topic (family roles) was represented in different contexts and by different users, and further focused on how the possible differences were handled in multilingual thesaurus construction. The second question was based on findings of the previous one, and answered to the final question as to what kinds of factors should be considered when defining translation equivalence in multilingual thesaurus construction. The study used multiple cases and several data collection and analysis methods aiming at theoretical replication and complementarity. The empirical material and analysis consisted of focused interviews (with Finnish and British social scientists, thesaurus constructors and indexers), simulated indexing tasks with Finnish and British indexers, semantic component analysis of dictionary definitions and translations, coword analysis and datasets retrieved in databases, and discourse analysis of thesauri. As a terminological starting point a topic and case family roles was selected. The results were clear: 1) It was possible to identify different discourses. There also existed subdiscourses. For example within the group of social scientists the orientation to qualitative versus quantitative research had an impact on the way they reacted to the studied words and discourses, and indexers placed more emphasis on the information seekers whereas thesaurus constructors approached the construction problems from a more material based solution. The differences between the different specialist groups i.e. the social scientists, the indexers and the thesaurus constructors were often greater than between the different geo-cultural groups i.e. Finnish versus British. The differences occurred as a result of different translation aims, diverging expectations for multilingual thesauri and variety of practices. For multilingual thesaurus construction this means severe challenges. The clearly ambiguous concept of multilingual thesaurus as well as different construction and translation strategies should be considered more precisely in order to shed light on focus and equivalence types, which are clearly not self-evident. The research also revealed the close connection between the aims of multilingual thesauri and the pragmatic indexing term equivalence. 2) The pragmatic indexing term equivalence is very much context-depended. Although thesaurus term equivalence is defined and standardised in the field of library and information science (LIS), it is not understood in one established way and the current LIS tools are inadequate to provide enough analytical tools for both constructing and studying different kinds of multilingual thesauri as well as their indexing term equivalence. The tools provided in translation science were more practical and theoretical, and especially the division of different meanings of a word provided a useful tool in analysing the pragmatic equivalence, which often differs from the ideal model represented in thesaurus construction literature. The study thus showed that the variety of different discourses should be acknowledged, there is a need for operationalisation of new types of multilingual thesauri, and the factors influencing pragmatic indexing term equivalence should be discussed more precisely than is traditionally done.

The study focuses on primary school teachers’ perceptions of environmental education, its integration into primary school education and teachers’ teaching practices in Tanzania. The thesis is based on empirical research. The theoretical underpinnings of the study are based on Palmer’s (1998) model of environmental education. According to the model, meaningful environmental education should include education about, in or through and for the environment. The study is supported by national and international literature from research done on environmental education and education for sustainable development and policy statements. The study is qualitative in nature, adopting phenomenography and phenomenology as points of departure. The empirical data was collected from four primary schools in Morogoro region in Tanzania. The study sample consisted of 31 primary school teachers. Data was collected through interviews and lesson observations. According to the results of the study, primary school teachers expressed variations in their perceptions of environmental education and education for sustainable development. Most of the teachers focused on the aspect of knowledge acquisition. According to Tanzanian education and training policy, environmental education has to be integrated into all subjects. Although there is environmental education in the primary school curriculum, it is not integrated on an equal footing in all subjects. Some subjects like science, social studies and geography have more environmental content than other subjects. Teachers claim that the approach used to integrate environmental education into the school curriculum was not favoured because many claimed that what is to be taught as environmental education in the various subjects is not shown clearly. As a result, many teachers suggested that to ensure that it is taught properly it should be included in the curriculum as an independent subject or as specific topics. The study revealed that teachers’ teaching practices in integrating environmental education varied from one subject to another. Although most of the teachers said that they used participatory methods, lesson observations showed that they limited themselves to question and answer and group discussion. However, the teachers faced a number of barriers in the teaching of environmental education, some of which include lack of teaching and learning resources, time and large class size. The role of teachers in the implementation of environmental education in developing an environmentally literate citizenry is of great significance. The responsibility of the government in developing a curriculum with clear goals and content, developing teachers’ capacity in the teaching of environmental education and provision of teaching and learning materials needs to be taken seriously by the government in educational plans and programs.

Saimaan ammattikorkeakoulun uudessa Luotsi-toimintamallissa opiskelijat oppivat yritysten antamia toimeksiantoja toteuttamalla. Opiskelijat perustavat oman osuuskuntamuotoisen tiimiyrityksen. Suuri osa opetussuunnitelman opintojaksoista toteutetaan tehden asiakasprojekteja. Tutkielman päätavoitteena on selvittää, mitkä ovat palvelun laadun dimensiot osuuskuntamuotoisissa opinnoissa ja millaisina opiskelijat ne kokevat. Tavoitteina on myös käsitellä tapaa, joilla palvelun laatu muodostuu korkeakouluissa sekä tutkia miksi asiakastyytyväisyyttä mitataan ja millaiseksi se koetaan. Teorian pohjalta päädytään tarkastelemaan viittä koulutuksen dimensiota, jotka ovat osa korkeakoulun palvelun laatua ja vaikuttavat asiakastyytyväisyyteen: opetussuunnitelma, oppimisympäristöt, opetusmenetelmät, ohjaus ja opetus sekä osaamisen arviointi. Empiirisen tutkimuksen kohderyhmänä on Luotsi-mallissa aloittanut liiketalouden pilottiryhmä. Tutkimuksessa käytetään kyselylomaketta sekä teemahaastattelua ryh-mälle. Kyselylomake koostuu 108 kysymyksestä, jotka on jaettu kolmeen osaan: tärkeyden, odotusten ja nykytilan arviointiin seitsenportaisella Li-kert-asteikolla. Haastattelun avulla syvennetään aineistoa. Tulokseksi saadaan attribuuttien ja dimensioiden tärkeysjärjestys sekä arvot nykytilalle, odotuksille ja niiden erotukselle. Tulosten pohjalta nostetaan esiin attribuutit, jotka tarvitsevat eniten kehitystoimia. Tutkimusten perusteella voidaan todeta, että eniten kehitystä vaatii ope-tussuunnitelma ja siihen välillisesti liittyvät attribuutit muista dimensioista. Suurin kynnys Luotsi-toimintamallin onnistumiselle on saavuttaa opiskelijoiden ja opettajien välille toimiva keskusteluyhteys sekä kehittää jatkuvasti opetussuunnitelmaa työelämälähtöisemmäksi.

Denne avhandlinga er resultatet av eit behov for å forske på og utvikle ein didaktikk for tekstilfaget ved Folkekunststudiet, Institutt for folkekultur, Høgskolen i Telemark, Noreg. Studiet med folkekunst som fagfelt er eit relativt ungt studium på høgskolen, som vart etablert i 1984. Problemstillinga i denne avhandlinga er korleis ein kan utvikle ein forskingsbasert didaktikk der dei grunnleggjande prinsippa som særmerkjer den tradisjonelle folkekunsten, vert tekne vare på. I arbeidet med avhandlinga har eg prøvd på å klårgjere problemstillinga ut frå ulike perspektiv. Forskingsarbeidet har fokus på kommunikasjon og arbeidsmåtar i ljos av ulike teoriar. Det er ei hermeneutisk tilnærming som er vald for den didaktiske forståinga. Det fyrste drøftingstemaet har søkjeljos på kommunikasjon og dialog ved vidareføring av tekstil folkekunst. Både estetiske, teoretiske, praktiske og sosiale aspekt er nedfelte i læreplanen for studiet og skal utgjere grunnlaget for kommunikasjon og arbeidsmåtar. I den skapande og kopierande prosessen er det utvikla språklege reiskapar for både den sosiale og den estetiske sida der den teoretiske og praktiske faktoren er integrert. Møte med døme på tekstile tradisjonar så vel som praktisk forming av tekstilar har ført til refleksjon og dialog som involverer kontemplasjon, korrespondens og imaginasjon. Det andre temaet som er drøfta, er vidareføring av tradisjonelt visuelt formspråk. Her er merksemda retta mot kva som har skjedd formalt med ei gruppe tradisjonelle formelement i tekstilar i den institusjonelle vidareføringa over eit lengre tidsperspektiv. Resultatet syner at mange tradisjonelle formelement er borte frå den institusjonelle produksjonen. Formelementa kan ha fått ei meir naturalistisk utforming, eller dei er overførte til andre tradisjonelle tekstilteknikkar enn dei som var utgangspunktet. Rombeforma i den institusjonelle produksjonen er utført i færre variasjonar og kombinasjonar enn i den tradisjonelle produksjonen. Konklusjonen på drøftingstemaet er at spelereglar og spatialitet i høve til den formale komponenten i utvalet med tradisjonelle tekstilar ikkje er vidareført i alle gruppene av institusjonelle produkt. Resultatet kan få innverknad og fylgjer for utforming av ein framtidig didaktikk for faget. Arbeidsmåte og erfaring frå vidareføring av tekstile tradisjonar er det tredje temaet som er drøfta i avhandlinga. Kopiering og skapande prosessar er arbeidsmåtar som er brukte ved studiet i dag, og dei utgjer grunnlag for drøftingar i relasjon til vidareføring og erfaring. Konklusjonen er at i den skapande prosessen korrigerer tradisjonen utforminga, medan i kopiprosessen er eigen stilvilje og improvisering resultat av prosessane. Personar som deltek i prosessane, har sett seg sjølve og si historiske forankring inn i spelet, der visuelt og verbalt språk er resultat av integrasjon av tradisjonar. Dei tre drøftingstemaa utgjer grunnlaget for at didaktikk for folkekunst og tekstil kan bli intersubjektiv forståing av kva ein didaktikk for vidareføring av folkekunst med vekt på tekstil kan vere i utdanninga i dag. Indre og ytre dialog i skapande og kopierande prosessar femner om estetiske, materielle og tekniske faktorar sett i høve til spelereglar, spelerom, spatialitet og samspel i møte med tekstile tradisjonar. Samla utgjer det ein forskingsbasert didaktikk for faget der den overordna intensjonen er samtykke mellom tradisjon og spel.

Brands have become one of the most valuable assets for organizations, which is why organizations want to benefit from them in whole scale. However, service concept brands are still little researched. The purpose of this research is to study how brand stretching and co-branding strategies can help a service concept brand to attain wider target market. More specifically, this research aims to contribute the methods and their risks and benefits to different customer levels of a group fitness brand. This study is a qualitative single case analysis embedded with multiple units of analysis. The data used in this study was gathered by nine theme interviews. The interviewees are from one of the customer levels of the service concept provided by the case organization. The interviews are made in different geographical areas in Finland. The results of the study will clarify and illustrate the differences and similarities between the theoretical framework and practise. Several differences between traditional brand stretching and co-branding strategies and those that are possible to employ by a service concept brand were found. The answers of the interviewees were slightly different depending on their role in the organization and their experience from the branch. However, they proved that not all brand stretching or co-branding strategies are applicable in the group fitness brand. Nevertheless, also several similarities that benefit the group fitness brand were found.

The construction material sector, as a capital intensive industry, is highly vulnerable to rapid fluctuations in the economic cycles. In Finland this was witnessed especially during the late 2000s, as in 2007 and 2008 the demand for several construction materials exceeded their supply and right after this, in 2009 the demand collapsed fast as a result of an international recession. These factors brought about the need to study the future trends of the market place of the commissioning company, Finnsementti Oy. As reliable short term market forecasts for the sector are difficult to compose, the study concentrates primarily in examining and identifying the trends that are likely to affect the Finnish cement industry, and as an extension, the concrete industry in a frame of 10 to 15 years. The study’s scope comprehends also the examination of the domestic construction sector, as it represents the end user industry of both cement and concrete. These motives for the study produce the research problem, which is to conduct a trend analysis for cement based building in the Finnish market area in the 2020s. The theoretical frame for composing a trend analysis in the case of this study is twofold. This is due to the fact that both, the macro and micro environments of the examined industries are studied. The main methods used are the PESTE-model (macro) and Porter’s five forces model (micro). The study applies a qualitative approach and the data is gathered by interviewing a group of experts from the cement, concrete and construction industries. The result of the paper is an overall trend analysis for the Finnish cement based building sector, which is based on ‘sub trend analyses’ concerning four identified sub-sectors of the Finnish construction industry. The results are a combination of findings from these sub-sectors and the analyzed data that deals with the studied sector’s macro and micro environment. The conclusions provide an overall picture of the examined sectors’ potential future as a whole and by defined sub-sectors of the construction industry. The recognition of future trends in different areas of the construction industry can be applied as a means for an industry actor’s decision making and in estimating the types of construction that are likely to grow or decline. Finally, based on the analyzed data and conclusions, the commissioning company is provided with a brief SWOT analysis, that provides additional tools for decision making and planning processes regarding the future.

There are vast changes in the work environment, and the traditional rules and management methods might not be suitable for today’s employees anymore. The meaning of work is also changing due to the younger and higher educated generations entering the markets. Old customs need to be re-validated and new approaches should be taken into use. This paper strongly emphasizes the importance of happiness research and happiness at work. The values towards the meaning of work are changing; people demand happiness and quality from all aspects of their lives. The aim of this study is to define happiness - especially at work - and to explain how it can be measured and what kind of results achieved. I also want to find out how the contents of work and the working environment might enhance happiness. The correlation between education and happiness is discussed and examined. I am aware that the findings and theories are concentrating mainly on Western Countries and highlighting the values and work-environments of those societies. The main aim of the empirical study is to find out if there are connections between happiness and work in data collected by World Value Survey in 2005, and if the profession has effects on happiness. Other factors such as the correlation of age, sex, education and income are examined too. I also want to find out what kind of values people have towards work and how these affect the happiness levels. The focus is on two nations: Finland (N=1014) and Italy (N=1012). I have also taken the global comparison within, that is all 54 countries (N=66,566) included in the 5th wave (during the years 2005 -2008) of the World Value Survey. The results suggest that people are generally happy around the world; happiness decreasing with the age, the educated being happier than the uneducated and the employed happier than the unemployed. People working in neat “white collar” jobs are more likely happier than those working in factories or outdoors. Money makes us happier, until certain level is reached. Work is important to people and the importance of work adds happiness. Work is also highly appreciated, but there are more happy people among those who do not appreciate work that highly. Safety matters the most when looking for a job, and there are more happy people among those who have selected the importance of work as the first choice when looking for a job, than among those to whom an income is the most important aspect. People are more likely happy when the quality of work is high, that is when their job consists of creative and cognitive tasks and when they have a feeling of independence.

Energy efficiency is one of the major objectives which should be achieved in order to implement the limited energy resources of the world in a sustainable way. Since radiative heat transfer is the dominant heat transfer mechanism in most of fossil fuel combustion systems, more accurate insight and models may cause improvement in the energy efficiency of the new designed combustion systems. The radiative properties of combustion gases are highly wavelength dependent. Better models for calculating the radiative properties of combustion gases are highly required in the modeling of large scale industrial combustion systems. With detailed knowledge of spectral radiative properties of gases, the modeling of combustion processes in the different applications can be more accurate. In order to propose a new method for effective non gray modeling of radiative heat transfer in combustion systems, different models for the spectral properties of gases including SNBM, EWBM, and WSGGM have been studied in this research. Using this detailed analysis of different approaches, the thesis presents new methods for gray and non gray radiative heat transfer modeling in homogeneous and inhomogeneous H2O–CO2 mixtures at atmospheric pressure. The proposed method is able to support the modeling of a wide range of combustion systems including the oxy-fired combustion scenario. The new methods are based on implementing some pre-obtained correlations for the total emissivity and band absorption coefficient of H2O–CO2 mixtures in different temperatures, gas compositions, and optical path lengths. They can be easily used within any commercial CFD software for radiative heat transfer modeling resulting in more accurate, simple, and fast calculations. The new methods were successfully used in CFD modeling by applying them to industrial scale backpass channel under oxy-fired conditions. The developed approaches are more accurate compared with other methods; moreover, they can provide complete explanation and detailed analysis of the radiation heat transfer in different systems under different combustion conditions. The methods were verified by applying them to some benchmarks, and they showed a good level of accuracy and computational speed compared to other methods. Furthermore, the implementation of the suggested banded approach in CFD software is very easy and straightforward.

The study investigates organisational learning and knowledge acquisition of wood-based prefabricated building manufacturers. This certain group of case companies was chosen, because their management and their employees generally have a strong manufacturing and engineering background, while the housing sector is characterised by national norms, regulations, as well as local building styles. Considering this setting, it was investigated, how the case companies develop organisational learning capabilities, acquire and transfer knowledge for their internationalisation. The theoretical framework of this study constitutes the knowledge-based conceptualisation of internationalisation, which combines the traditional internationalisation process, as well as the international new venture perspective based on their commonalities in the knowledge-based view of the firm. Different theories of internationalisation, including the network-perspective, were outlined and a framework on organisational learning and knowledge acquisition was established. The empirical research followed a qualitative approach, deploying a multiple-case study with five case companies from Austria, Finland and Germany. In the study, the development of the wood-based prefabricated building industry and of the case companies are described, and the motives, facilitators and challenges for foreign expansion, as well as the companies’ internationalisation approaches are compared. Different methods of how companies facilitate the knowledge-exchange or learn about new markets are also outlined. Experience, market knowledge and personal contacts are considered essential for the internationalisation process. The major finding of the study is that it is not necessary to acquire the market knowledge internally in a slow process as proposed by the Uppsala model. In four cases companies engaged knowledge in symbiotic relations with local business partners. Thereby, the building manufacturers contribute their design and production capabilities, and in return, their local partners provide them with knowledge about the market and local regulations; while they manage the sales and construction operations. Thus, the study provides strong evidence for the propositions of network perspective. One case company developed the knowledge internally in a gradual process: it entered the market sequentially with several business lines, showing an increasing level of complexity. In both of the observed strategies, single-loop and double-loop learning processes occurred.
