Finnish buyers’ perceptions of Indian textile and clothing suppliers: Country of origin in focus

Choosing the right supplier is crucial for long-term business prospects and profitability. Thus organizational buyers are naturally very interested in how they can select the right supplier for their needs. Likewise, suppliers are interested in knowing how their customers make purchasing decisions in order to effectively sell and market to them. From the point of view of the textile and clothing (T&C) industry, regulatory changes and increasing low-cost and globalization pressures have led to the rise of low-cost production locations India and China as the world’s largest T&C producers. This thesis will examine T&C trade between Finland and India specifically in the context of non-industrial T&C products. Its main research problem asks: what perceptions do Finnish T&C industry buyers hold of India and Indian suppliers? B2B buyers use various supplier selection models and criteria in making their purchase decisions. A significant amount of research has been done into supplier selection practices, and in the context of international trade, country of origin (COO) perceptions specifically have garnered much attention. This thesis uses a mixed methods approach (online questionnaire and in-depth interviews) to evaluate Finnish T&C buyers’ supplier selection criteria, COO perceptions of India and experiences of Indian suppliers. It was found that the most important supplier selection criteria used by Finnish T&C buyers are quality, reliability and cost. COO perceptions were not found to be influential in purchasing process. Indian T&C suppliers’ strengths were found to be low cost, flexibility and a history of traditional T&C expertise. Their weaknesses include product quality and unreliable delivery times. Overall, the main challenges that need to be overcome by Indian T&C companies are logistical difficulties and the cost vs. quality trade-off. Despite positive perceptions of India for cost, the overall value offered by Indian T&C products was perceived to be low due to poor quality. Unreliable delivery time experiences also affected buyer’s reliability perceptions of Indian suppliers. The main limiting factors of this thesis relate to the small sample size used in the research. This limits the generalizability of results and the ability to evaluate the reliability and validity of some of the research instruments.

Perceptions of green branding and identity building amongst small Finnish textile producers

The textile industry is one of the most polluting industries in the world. The amount of air and water pollution it causes puts a burden on the environment. There are companies who have taken the environmental and social aspects into account in the their production and chosen to operate in a green manner. This thesis studies how the phenomenon of green branding is seen from the perspectives of small Finnish textile companies. The theory used in this thesis has to do with green branding and identity building. The theory is used to analyze the results of the empirical findings. The main research question that the thesis aims to answer is how green branding is perceived within the Finnish textile industry. In order to answer the main research question, empirical data was collected from five relevant companies within the Finnish textile industry. The companies interviewed for the study were WST, Saana ja Olli, RCM, R-collection and Tiensivu. The study was conducted as a multiple case based study where multiple experts from green companies were interviewed. The experts were all owners or employees of companies that have a so-called green brand identity. The data was collected through semi-structured interviews, where the relevant experts from each company were interviewed either by themselves, in pairs or in groups. The data that was collected for this study was primary data, and the results of the study are mainly based on the experiences and opinions of the experts interviewed. The data collected does not cover the entire green textile industry within Finland, but study does however give a fairly comprehensive view of the phenomenon, as the textile industry in Finland is quite concise. The general findings of the study show that all experts from the companies interviewed agreed that a green brand identity does benefit their company in one way or the other. The findings also show contradictions with the older theory (eg. Charter et al. 1999, Pickett et al. 1995), and perhaps give a more modern view of the thoughts within the industry.

Purification and fractionation by nanotiltration in dairy and sugar and sweetener industry applications

Nanotiltration is a membrane separation method known for its special characteristic of rejecting multivalent ions and passing monovalent ions. Thus, it is commonly applied with dilute aqueous solutions in partial salt removal, like in drinking water production. The possibilities of nanofiltration have been studied and the technique applied in a wide branch of industries, e.g. the pulp and paper, the textile and the chemical processing industry. However, most present applications and most of the potential applications studied involve dilute solutions, the permeating stream being generally water containing monovalent salts. In this study nanotiltration is investigated more as a fractionation method. A well-known application in the dairy industry is concentration and partial salt removal from whey. Concentration and partial demineralization is beneficial for futher processing of whey as whey concentrates are used e.g. in baby foods. In the experiments of this study nanotiltration effectively reduced the monovalent salts in the whey concentrate. The main concern in this application is lactose leakage into the permeate. With the nanofiltration membranes used the lactose retentions were practically ? 99%. Another dairy application studied was the purification and reuse of cleaning solutions. This is an environmentally driven application. An 80% COD reduction by nanofiltration was observed for alkaline cleaning-in-place solution. Nanofiltration is not as commonly applied in the sugar and sweeteners industry as in the dairy industry. In this study one potential application was investigated, namely xylose purification from hemicellulose hydrolyzate. Xylose is raw material for xylitol production. Xylose separation from glucose was initially studied with xylose-glucose model solutions. The ability of nanofiltration to partially separate xylose into the permeate from rather concentrated xylose-glucose solutions (10 w-% and 30 w-%) became evident. The difference in size between xylose and glucose molecules according to any size measure is small, e.g. the Stokes diameter of glucose is 0.73 nm compared to 0.65 nm for xylose. In further experiments, xylose was purified into nanoliltration permeate from a hemicellulose hydrolyzate solution. The xylose content in the total solids was increased by 1.4—1.7 fold depending on temperature, pressure and feed composition.

Vaatetus- ja tekstiilimateriaalien ekologinen elinjakson hallinta Talousvarikon toiminnoissa

Tämän case -tutkimuksen tarkoituksena on kartoittaa tekstiili- ja vaatetusmateriaalien ekologista elinjakson hallintaa Talousvarikon toiminnoissa ja tutkimalla mahdollisuuksia soveltaa saatuja tuloksia. Talousvarikko on Puolustusvoimien Materiaalilaitoksen alainen järjestelmävastuuvarikko, jonka tehtävänä on varusmiesten ja kadettien vaatetuksen hankinta- ja ylläpitotoiminnot. Talousvarikko jakautuu neljälle paikkakunnalle. Hämeenlinnassa on hankinta-, hallinto- ja materiaaliosasto. Säkylässä, Mikkelissä ja Sodankylässä ovat vaatetuskorjaamot. Tekstiilimateriaalien elinkaariajattelussa tarkastellaan raaka-aineiden jaottelua ja maailman kuitutuotantoa. Tekstiilikuidut jaotellaan luonnon- ja tekokuituihin. Luonnonkuidut ovat pääosin luonnon raaka-aineita ja tekokuidut ovat synteettisesti valmistettuja. Tekstiilikuitujen- ja materiaalien vaikutus ekologiseen elinjakson hallinnan vaiheisiin on riippuvainen raaka-aineidenalkuperästä. Vaatetus- ja tekstiilimateriaalin elinkaari muodostuu tuotekehityksestä, hankinnasta, valmistuksesta, käytöstä, huollosta ja hylkäyksestä. Ekologista elinjakson hallintaa tarkastellaan materiaalivirta- ja elinkaarianalyysien kautta. Elinkaarianalyysin tarkastelu painottuu vaikutusluokkien arvottamiseen ja materiaalivirta-analyysissä tarkastellaan ainevirtoja ja sitä kautta jätteiden määrän vähentämistä. Joutsenmerkin valintakriteerien pohjana on aina tuotteiden elinkaarianalyysi. Joutsenmerkin valintakriteerien soveltaminen Talousvarikon toimintoihin vaatetus- ja tekstiilimateriaalin elinkaaren jokaisessa vaiheessa antaa mahdollisuuden lisätä ekologista elinkaaren hallintaa Talousvarikon toiminnoissa. Ympäristönäkökohtien huomioiminen tuotekehityksessä ja hankinnoissa antaa mahdollisuuden tehdä tilauksia / sopimuksia yhteiskuntavastuullisilta yrityksiltä huomioiden valmistuksen yhdeksi osaksi hankinta ja logistiikka pääprosessia.

Onnistuneen uuden tuotteen kehittäminen ja hallinta - Tapaustutkimus: Tekstiilialan yritys

Tuotesuunnittelu on yrityksen selviämisen kannalta erittäin tärkeä toiminto. Menestynyt tuotesuunnittelu vaatii selkeän tuotestrategian, laadukkaasti suoritetun tuotesuunnitteluprosessin ja tarvittavienresurssien yhdistämistä sekä uuden tuotteen tuottojen hallintaa myynnin seurannalla. Kohdeyrityksessä uusien tuotteiden suunnittelun ja hallinnan tärkeys on huomattu ja niiden kehittämiseksi yritys on lisäämässä panostustaan. Tämä tutkimuspyrkii tuomaan kohdeyrityksen tietoon tuotesuunnitteluun ja uuden tuotteen hallintaan vaikuttavat menestystekijät sekä tuomaan esille näitä toimintoja tukevia kehittämismahdollisuuksia. Tutkimus on normatiivinen tapaustutkimus, jossa teoria on koottu tieteellisistä, lähinnä empiirisistä tutkimuksista koostuvista artikkeleista. Yrityksen tuotesuunnitteluun liittyvät prosessit ja toiminnot on selvitetty puolistrukturoiduilla haastatteluilla sekä havainnoimalla. Tutkimuksessa havaittiin selkeitä eroja uuden tuotteen hallinnan menestystekijöiden ja yrityksen toimintojen välillä. Tuotesuunnitteluprosessin uudelleen organisointi, toimitusketjun hallinta ja tuotekohtainen kustannuslaskenta ovat asioita, joita kehittämällä yritys voi mahdollisesti parantaa uusien tuotteiden elinkaaren aikaista hallintaa ja taloudellista onnistumista sekä lisätä yrityksen kannattavuutta.

Discovering New Markets for an Industrial Product – International Market Selection Approach

Tämän tutkielman tavoitteena oli määrittää uuden markkinan valinnan perusteita teolliselle tuotteelle. Tutkielma keskittyi jo tunnettuihin kansainvälisen markkinavalinnan lähestymistapoihin ja pyrki soveltamaan yhtä menetelmää käytäntöön tutkielman empiria osassa case-tutkimuksen avulla. Tutkimusote oli tutkiva, eksploratiivinen ja perustui sekundääri analyysiin. Käytetyt tiedon lähteet olivat suureksi osin sekundäärisiä tuottaen kvalitatiivista tietoa. Kuitenkin haastatteluita suoritettiin myös. Kattava kirjallisuus katsaus tunnetuista teoreettisista lähestymistavoista kansainväliseen markkinavalintaan oli osa tutkielmaa. Kolme tärkeintä lähestymistapaa esiteltiin tarkemmin. Yksi lähestymistavoista, ei-järjestelmällinen, muodosti viitekehyksen tutkielman empiria-osalle. Empiria pyrki soveltamaan yhtä ei-järjestelmällisen lähestymistavan malleista kansainvälisessä paperiteollisuudessa. Tarkoituksena oli tunnistaa kaikkein houkuttelevimmat maat mahdollisille markkinointitoimenpiteille tuotteen yhdellä loppukäyttöalueella. Tutkielmassa päädyttiin käyttämään ilmastollisia olosuhteita, siipikarjan päälukua sekä siipikarjan kasvuprosenttia suodattimina pyrittäessä vähentämään mahdollisten maiden lukumäärää. Tutkielman empiria-osa kärsi selkeästi relevantin tiedon puutteesta. Siten myös tutkielman reliabiliteetti ja validiteetti voidaan jossain määrin kyseenalaistaa.

Elastomeerien kesto viherlipeäkäsittelyissä

Työssä on tutkittu eri kumilaatujen soveltuvuutta viherlipeäympäristöön laboratoriomittausten avulla. Kumia tultaisiin käyttämään viherlipeälinjan letkuventtiilissä. Suomalaisista sellutehtaista saaduista viherlipeänäytteistä mitattiin alkali- ja vierasainepitoisuudet. Kumitestauksissa viherlipeässä pyrittiin selvittämään kumien kesto prosessiolosuhteita vastaavissa olosuhteissa. Kumit asetettiin kuumaan viherlipeään jännitettynä ja pidettiin siinä kolme vuorokautta. Kumista tutkittavia ominaisuuksia olivat kumin massan muutos, kovuus, vetolujuus sekä murtovenymä. Kolmen vuorokauden testien tulosten perusteella valittiin kolme kumilaatua tuhannen tunnin kestotestiin, joissa seurattiin kumin massan käyttäytymistä sekä kumin pitkäaikaisen altistamisen viherlipeässä vaikutusta lujuusominaisuuksiin. Kokeissa havaittiin osan testatuista kumeista sitovan viherlipeää itseensä, mikä aiheuttaisi viherlipeän pääsyn letkun vahvikkeisiin ja aiheuttaisi letkun hajoamisen. Osa kumeista kului kemiallisesti, mikä taas aiheuttaisi letkun rasitustilanteissa repeämiä letkun pinnassa ja lopulta letkun hajoamisen. Kuitenkin suuressa osassa testatuissa kumimateriaaleissa ei ollut suuria massanmuutoksia. Tällöin lujuusmittaukset kertoivat muilta osin kumin kestosta. Muutamilla kumeilla massanmuutokset olivat alhaisia, mutta lujuusarvot olivat romahtaneet. Kuitenkin laboratoriomittausten tulosten perusteella pystyttiin löytämään kumimateriaali, joka kestäisi paremmin viherlipeäprosessissa kuin teollisuudessa käytössä ollut kumimateriaali. Kuitenkin lopullinen varmuus tästä voidaan saada teollisuudessa tehtyjen testausten avulla.

Radanohjaimen suunnittelu leveille päällystyskoneille

Radanohjaimia käytetään radan poikkisuuntaiseen paikoitukseen sekä oskillointiin ja ne ovat osa paperinvalmistuslinjojen radanhallintajärjestelmiä. Oikein suunnitellulla ja sijoitetulla radanohjaimella voidaan estää haitallisten ratasiirtymien esiintyminen, pienentää hylkymateriaalin määrää sekä parantaa rullauksen laatua. Ohjausperiaatteet sekä niihin liittyvä laitetekniikka on tunnettu jo vuosikymmenten ajan, joskin todelliset radanohjaustarpeet ja -laitteet ovat tähän asti rajoittuneet paino-, tekstiili- ja metalliteollisuudessa käytössä oleville kapeille radoille. Tämän työn tavoitteena oli selvittää 5… 12 metriä leveälle, modernissa päällystyskoneessa kulkevalle paperiradalle soveltuvat ohjausperiaatteet sekä muodostaa radan todennäköisimpiin vauriomuotoihin perustuvat suunnittelukriteerit kahdelle erityyppiselle ohjainkonstruktiolle. Yksitelainen, taivuttava radanohjain soveltuu kohteisiin, joissa ohjainta edeltää suhteellisen pitkä vapaa ratavienti. Kaksitelainen, taittava radanohjain on puolestaan sijoitettavissa huomattavasti lyhyempään ratavientiin. Radanohjauksen teoria pohjautuu pitävän telan ja radan väliseen kohtisuoran tulokulman periaatteeseen, jonka perusteella mikä tahansa yhdensuuntaisuuspoikkeama kahden telan välillä johtaa radan poikkisuuntaiseen siirtymään. Tämän periaatteen pohjalta voidaan dynaamista ohjaustilannetta approksimoida staattisin menetelmin sekä muodostaa kireysmuutoksiin ja aaltoiluun perustuvat geometrian mitoitusperiaatteet ohjaimen ympäristön ratavienneille. Nopean ohjauksen toteutus edellyttää radanohjaimen liikkeen olevan nivelen ympäri tapahtuvaa yhdistettyä translaatio- ja rotaatioliikettä. Ohjainkonstruktiot suunnitellaan siten, että teorian mukaiset optimaaliset liikeradat toteutuvat vaaditulla ohjausnopeudella. Suunnittelua ohjaavat tuotteille asetetut lujuus- ja värähtelykriteerit sekä aiheeseen liittyvät koneturvallisuusstandardit. Konstruointi suoritetaan järjestelmällisen tuotesuunnitteluprosessin vaiheiden ja menetelmien mukaisesti.

Kangasmallista tuotteeksi – suunnittelun vaikutus naisten vaatteen loppukustannukseen

Vaatteiden valmistusprosessissa suunnittelupäätöksillä kiinnitetään noin 70 — 90 % vaatteen loppukustannuksista. Tutkielman tavoitteena on ollut lisätä erityisesti vaatesuunnittelijoiden kustannustietoisuutta ja osoittaa kuinka he voivat valinnoillaan vaikuttaa vaatteen loppukustannuksiin. Tutkielmassa on havainnollisesti esitetty erilaisten variaatioiden lukumäärä ja niiden moninkertaistuminen tuotantoprosessissa. Tutkielmassa on esitelty myös erilaisia kustannuslaskentamenetelmiä, joilla voidaan laskea tuotteen loppukustannuksia tai vaikuttaa esim. lopulliseen tuotantoon valittavien tuotteiden valintaan. Tutkimuksessa havaittiin vaatealan heikko kustannustuntemus ja johtopäätöksenä oli lisätä huomattavasti suunnittelijoiden kustannuslaskentakoulutusta. Tutkimus on ns. abduktiivinen eli tutkimusaiheen teoriaa käsitellään rinnakkain empiirisen, kokemusperäisen tutkimuksen kanssa. Tutkielma on myös ns. single case tapaustutkimus, jossa tutkimuksen kohteena on käytetty vain yhtä vaatealan yritystä Suomessa. Kohdeyrityksessä on haastateltu sekä vaatesuunnittelijoita että muita suunnittelu- ja tuotantoprosessiin osallistuvia henkilöitä.

Development of Russian Ports in The Gulf of Finland

Russia has been one of the fastest developing economic areas in the world. Based on the GDP, the Russian economy grew evenly since the crisis in 1998 up till 2008. The growth in the gross domestic product has annually been some 5–10%. In 2007, the growth reached 8.1%, which is the highest figure after the 10% growth in 2000. Due to the growth of the economy and wage levels, purchasing power and consumption have been strongly increasing. The growing consumption has especially increased the imports of durables, such as passenger cars, domestic appliances and electronics. The Russian ports and infrastructure have not been able to satisfy the growing needs of exports and imports, which is why quite a large share of Russian foreign trade is going through third countries as transit transports. Finnish ports play a major role in transit transports to and from Russia. About 15% of the total value of Russian imports was transported through Finland in 2008. The economic recession that started in autumn 2008 and continues to date has had an impact on the economic development of Russia. The export income has decreased, mainly due to the reduced world market prices of energy products (oil and gas) and raw minerals. Investments have been postponed, getting credit is more difficult than before, and the ruble has weakened in relation to the euro and the dollar. The imports are decreasing remarkably, and are not forecast to reach the 2008 volumes even in 2012. The economic crisis is reflected in Finland's transit traffic. The volume of goods transported through Finland to and from Russia has decreased almost in the same proportion as the imports of goods to Russia. The biggest risk threatening the development of the Russian economy over long term is its dependence on export income from oil, gas, metals, minerals and forest products, as well as the trends of the world market prices of these products. Nevertheless, it is expected that the GDP of Russia will start to grow again in the forthcoming years due to the increased demand for energy products and raw minerals in the world. At the same time, it is obvious that the world market prices of these products will go up with the increasing demand. The increased income from exports will lead to a growth of imports, especially those of consumer goods, as the living standard of Russian citizens rises. The forecasts produced by the Russian Government concerning the economic development of Russia up till 2030 also indicate a shift in exported goods from raw materials to processed products, which together with energy products will become the main export goods of Russia. As a consequence, Russia may need export routes through third countries, which can be seen as an opportunity for increased transit transports through the ports of Finland. The ports competing with the ports of Finland for Russian foreign trade traffic are the Russian Baltic Sea ports and the ports of the Baltic countries. The strongest competitors are the Baltic Sea ports handling containers. On the Russian Baltic Sea, these ports include Saint Petersburg, Kaliningrad and, in the near future, the ports of Ust-Luga and possibly Vyborg. There are plans to develop Ust-Luga and Vyborg as modern container ports, which would become serious competitors to the Finnish ports. Russia is aiming to redirect as large a share as possible of foreign trade traffic to its own ports. The ports of Russia and the infrastructure associated with them are under constant development. On the other hand, the logistic capacity of Russia is not able to satisfy the continually growing needs of the Russian foreign trade. The capacity problem is emphasized by a structural incompatibility between the exports and imports in the Russian foreign trade. Russian exports can only use a small part of the containers brought in with imports. Problems are also caused by the difficult ice conditions and narrow waterways leading to the ports. It is predicted that Finland will maintain its position as a transit route for the Russian foreign trade, at least in the near future. The Russian foreign trade is increasing, and Russia will not be able to develop its ports in proportion with the increasing foreign trade. With the development of port capacity, cargo flows through the ports of Russia will grow. Structural changes in transit traffic are already visible. Firms are more and more relocating their production to Russia, for example as regards the assembly of cars and warehousing services. Simultaneously, an increasing part of transit cargoes are sent directly to Russia without unloading and reloading in Finland. New product groups have nevertheless been transported through Finland (textile products and tools), replacing the lost cargos. The global recession that started in autumn 2008 has influenced the volume of Russian imports and, consequently, the transit volumes of Finland, but the recession is not expected to be of long duration, and will thus only have a short-term impact on transit volumes. The Finnish infrastructure and services offered by the logistic chain should also be ready to react to the changes in imported product groups as well as to the change in Russian export products in the future. If the development plans of the Russian economy are realized, export products will be more refined, and the share of energy and raw material products will decrease. The other notable factor to be taken into consideration is the extremely fast-changing business environment in Russia. Operators in the logistic chain should be flexible enough to adapt to all kinds of changes to capitalise on business opportunities offered by the Russian foreign trade for the companies and for the transit volumes of Finnish ports, also in the future.

Training system for conceptual design and evaluation for wastewater treatment

Rising population, rapid urbanisation and growing industrialisation have severely stressed water quality and its availability in Malawi. In addition, financial and institutional problems and the expanding agro industry have aggravated this problem. The situation is worsened by depleting water resources and pollution from untreated sewage and industrial effluent. The increasing scarcity of clean water calls for the need for appropriate management of available water resources. There is also demand for a training system for conceptual design and evaluation for wastewater treatment in order to build the capacity for technical service providers and environmental practitioners in the country. It is predicted that Malawi will face a water stress situation by 2025. In the city of Blantyre, this situation is aggravated by the serious pollution threat from the grossly inadequate sewage treatment capacity. This capacity is only 23.5% of the wastewater being generated presently. In addition, limited or non-existent industrial effluent treatment has contributed to the severe water quality degradation. This situation poses a threat to the ecologically fragile and sensitive receiving water courses within the city. This water is used for domestic purposes further downstream. This manuscript outlines the legal and policy framework for wastewater treatment in Malawi. The manuscript also evaluates the existing wastewater treatment systems in Blantyre. This evaluation aims at determining if the effluent levels at the municipal plants conform to existing standards and guidelines and other associated policy and regulatory frameworks. The raw material at all the three municipal plants is sewage. The typical wastewater parameters are Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS). The treatment target is BOD5, COD, and TSS reduction. Typical wastewater parameters at the wastewater treatment plant at MDW&S textile and garments factory are BOD5 and COD. The treatment target is to reduce BOD5 and COD. The manuscript further evaluates a design approach of the three municipal wastewater treatment plants in the city and the wastewater treatment plant at Mapeto David Whitehead & Sons (MDW&S) textile and garments factory. This evaluation utilises case-based design and case-based reasoning principles in the ED-WAVE tool to determine if there is potential for the tool in Blantyre. The manuscript finally evaluates the technology selection process for appropriate wastewater treatment systems for the city of Blantyre. The criteria for selection of appropriate wastewater treatment systems are discussed. Decision support tools and the decision tree making process for technology selection are also discussed. Based on the treatment targets and design criteria at the eight cases evaluated in this manuscript in reference to similar cases in the ED-WAVE tool, this work confirms the practical use of case-based design and case-based reasoning principles in the ED-WAVE tool in the design and evaluation of wastewater treatment 6 systems in sub-Sahara Africa, using Blantyre, Malawi, as the case study area. After encountering a new situation, already collected decision scenarios (cases) are invoked and modified in order to arrive at a particular design alternative. What is necessary, however, is to appropriately modify the case arrived at through the Case Study Manager in order to come up with a design appropriate to the local situation taking into account technical, socio-economic and environmental aspects. This work provides a training system for conceptual design and evaluation for wastewater treatment.

Under ytan, vid ytan och ovanför ytan : analys av tanken bakom tre läromedel i slöjd

This thesis is based on the personal experience gained related to the planning and production of three web-based teaching materials for the teaching subject knownas sloyd at the comprehensive school in Finland. After the teaching materials had been produced and published on the Internet at the Finnish textile teachers' website KässäBoxi, the idea for this thesis emanated from the questions: Why do the three teaching materials look the way they do and why do other textile teachers comment that they are different? In earlier sloyd educational research it has been stated that a scientific paradigm affects the individual ideology of a sloyd teacher. The aimfor my doctoral thesis is to continue on the topic. As the area of interest comprises the thought behind three teaching materials in sloyd, the aim of the thesis is to show how teaching and educational ideologies in sloyd appear in the teaching materials at hand. The research approach has parallels to research about another, tangible phenomena, namely the iceberg. In a similar way as an iceberg, a teaching material has a profound base, but the base is not always completely visible to the user of the teaching material. In this thesis I strive to show what there is under the surface, on the surface and above the surface of three teaching materials in sloyd. The research approach is defined as qualitative and phenomenologic-hermeneutic. The analysis results in knowledge about how the producer of a teaching material affects the character of a teaching material by choices concerning for example the form, structure, language and illustrations of the teaching material. The analysis also shows how the producers' individual educational and teaching ideologies within the teaching subject at hand appear by means of traces concerning the view on the pupil and the teacher, and the view on planning and conducting teaching in sloyd. The thesis also results in knowledge about how sloyd educational scientific theories and demands from society, as they are stated in the national core curriculum, appear in the three teaching materials. The application of the sloyd educational scientific theory of individual sloyd activity as a holistic educative system is also widened in the thesis. This thesis contributes to future research on producing teaching materials by information about what aspects a producer of teaching materials needs to consider and how the aspects become visible in the teaching materials. This kind of knowledge is valuable to teacher students in sloyd, to teachers in sloyd who intend to plan and produce teaching materials and to teachers who tutor the planning and production of teaching materials.
