Palvelun laadun rooli brandistrategian kehittämisessä

Tutkimuksen päätavoitteena on selvittää palvelun laadun rooli brandistrategian kehittämisessä. Tutkimuksen tekeminen nähtiin tarpeelliseksi, sillä palvelun laadun roolia brandistrategian kehittämisessä ei ole aiemmin paljolti tutkittu. Normatiivisella case-tutkimuksella pyritään löytämään konkreettisia brandistrategian kehittämiskohteita case-yritykselle niin strategisella kuin myös operationaalisella tasolla. Case-yrityksen toimiala ja tilanne huomioiden normatiiviselle case-tutkimukselle luodaan perusta tutkimuksen teoreettisessa osassa sovellettavilla teoreettisilla näkemyksillä ja malleilla. Tutkimusta käsitellään sekä kvalitatiivisten että kvantitatiivisten tutkimusmenetelmien keinoin. Tutkimuksen empiirinen osio perustuu yrityksen henkilökunnan haastatteluihin, tutkijan havainnointiin sekä case—yrityksen asiakkaille suoritettavaan asiakastutkimukseen. Tutkimus osoittaa, että palvelun laadun rooli on merkittävässä asemassa palveluyritysten brandistrategian kehittämisessä ja on samalla tärkein yksittäinen asiakastyytyväisyyteen vaikuttava tekijä. Tutkimus tuo esille konkreettisia toimenpide-ehdotuksia, jotka auttavat case-yritystä kehittämään brandistrategiaansa ja auttaa siten yritystä saavuttamaan kilpailuetua muuttuvassa toimintaympäristössä.

Competence Development and Capacity Building of Sawmill Enterprises in Kenya – A Human Resources Development Approach

The Kenyan forestry and sawmilling industry have been subject to a changing environment since 1999 when the industrial forest plantations were closed down. This has lowered raw material supply and it has affected and reduced the sawmill operations and the viability of the sawmill enterprises. The capacity of the 276 registered sawmills is not sufficient to fulfill sawn timber demand in Kenya. This is because of the technological degradation and lack of a qualified labor force, which were caused because of non-existent sawmilling education and further training in Kenya. Lack of competent sawmill workers has led to low raw material recovery, under utilization of resources and loss of employment. The objective of the work was to suggest models, methods and approaches for the competence and capacity development of the Kenyan sawmilling industry, sawmills and their workers. A nationwide field survey, interviews, questionnaire and literature review was used for data collection to find out the sawmills’ competence development areas and to suggest models and methods for their capacity building. The sampling frame included 22 sawmills that represented 72,5% of all the registered sawmills in Kenya. The results confirmed that the sawmills’ technological level was backwards, productivity low, raw material recovery unacceptable and workers’ professional education low. The future challenges will be how to establish the sawmills’ capacity building and workers’ competence development. Sawmilling industry development requires various actions through new development models and approaches. Activities should be started for technological development and workers’ competence development. This requires re-starting of vocational training in sawmilling and the establishment of more effective co-operation between the sawmills and their stakeholder groups. In competence development the Enterprise Competence Management Model of Nurminen (2007) can be used, whereas the best training model and approach would be a practically oriented learning at work model in which the short courses, technical assistance and extension services would be the key functions.

The governmental organization's role in railway freight market's liberalization -building knowledge through Swedish and Polish operators' experiences

Globalization has increased transport aggregates’ demand. Whilst transport volumes increase, ecological values’im portance has sharpened: carbon footprint has become a measure known world widely. European Union together with other communities emphasizes friendliness to the environment: same trend has extended to transports. As a potential substitute for road transport is noted railway transport, which decreases the congestions and lowers the emission levels. Railway freight market was liberalized in the European Union 2007, which enabled new operators to enter the markets. This research had two main objectives. Firstly, it examined the main market entry strategies utilized and the barriers to entry confronted by the operators who entered the markets after the liberalization. Secondly, the aim was to find ways the governmental organization could enhance its service towards potential railway freight operators. Research is a qualitative case study, utilizing descriptive analytical research method with a normative shade. Empirical data was gathered by interviewing Swedish and Polish railway freight operators by using a semi-structured theme-interview. This research provided novel information by using first-hand data; topic has been researched previously by utilizing second-hand data and literature analyses. Based on this research, rolling stock acquisition, needed investments and bureaucracy generate the main barriers to entry. The research results show that the mostly utilized market entry strategies are start-up and vertical integration. The governmental organization could enhance the market entry process by organizing courses, paying extra attention on flexibility, internal know-how and educating the staff.

Building the map of innovation for membrane materials (Ceramic membranes)

This work proposes a method of visualizing the trend of research in the field of ceramic membranes from 1999 to 2006. The presented approach involves identifying problems encountered during research in the field of ceramic membranes.

The identified problems are classified into major research issues. This classification was used for the visualization of the intensity of research. The image produced gives the relation between the number of patents, with time and the major research issues. The identification of the most cited papers which strongly influence the research of the previously identified major issues in the given field was also carried out. The relations between these papers are presented using the metaphor of social network. The final result of this work are two figures, a diagram showing the change in the studied problems a specified period of time and a figure showing the relations between the major papers and groups of the problems

Mobiiliavusteisen rakennusprojektin seurantajärjestelmän suunnittelu ja toteutus

In the construction industry, the role of project management and monitoring is emphasized, because the responsibilities have been carefully planned and divided. A concrete element factory manufactures the units based on construction drawings, while a transport company is responsible of transporting the elements to the worksite. At the worksite, an installation team assembles the elements according to plans. Usually, there are several manufacturers and transport companies involved in the construction process and the distances between different parties can be rather long. Therefore, the role of information exchange is critical in order to control, for example, schedules and exceptions. From the viewpoint of project management, the whole process should be controlled and monitored in realtime - in such a way that the managers are able to analyze and report the data afterwards. In this master’s thesis, a mobile-aided construction project monitoring system is designed and implemented. The monitoring system consists of three main components: mobile phone application, server software and an interface application to Tekla Structures BIM-software. Precast construction components, projects and users are identified by using 2D-barcodes that are read with the camera of a mobile phone. An option would be to use RFID tags and readers. After successful identification, the precast component can be tagged with monitoring data, including state acknowledgments and error reports that are sent and saved to the server. Collected data can be viewed through the www-pages of the monitoring system. In addition, the data can be synchronized to the Tekla Structures-software that is running the 3D-model of the whole building. Synchronization maintains and enhances the traceability of monitoring data, as well as, helps to visualize the progression of the project.

Distributed ControlArchitecture of Power Electronics Building-Block-Based Frequency Converters

The increasing power demand and emerging applications drive the design of electrical power converters into modularization. Despite the wide use of modularized power stage structures, the control schemes that are used are often traditional, in other words, centralized. The flexibility and re-usability of these controllers are typically poor. With a dedicated distributed control scheme, the flexibility and re-usability of the system parts, building blocks, can be increased. Only a few distributed control schemes have been introduced for this purpose, but their breakthrough has not yet taken place. A demand for the further development offlexible control schemes for building-block-based applications clearly exists. The control topology, communication, synchronization, and functionality allocationaspects of building-block-based converters are studied in this doctoral thesis. A distributed control scheme that can be easily adapted to building-block-based power converter designs is developed. The example applications are a parallel and series connection of building blocks. The building block that is used in the implementations of both the applications is a commercial off-the-shelf two-level three-phase frequency converter with a custom-designed controller card. The major challenge with the parallel connection of power stages is the synchronization of the building blocks. The effect of synchronization accuracy on the system performance is studied. The functionality allocation and control scheme design are challenging in the seriesconnected multilevel converters, mainly because of the large number of modules. Various multilevel modulation schemes are analyzed with respect to the implementation, and this information is used to develop a flexible control scheme for modular multilevel inverters.

From pioneering mission to autonomous church : Lutheran mission cooperation and church building in Thailand 1976-1994

Det lutherska missionsarbetet i Thailand startade inte förrän år 1976 då norska lutherska missionärer anlände till landet. Ett par år senare inledde Finska Missionssällskapet samarbete med norrmännen och med tiden anslöt sig även tre asiatiska lutherska kyrkor till missionssamarbetet i Thailand. Från första början var målet för missionsarbetet att grunda en självständig luthersk kyrka i Thailand. Detta skedde år 1994, 18 år efter att arbetet i Thailand hade inletts. I avhandlingen granskas vilka arbetsmetoder och verksamhetsformer som användes och hur grundandet av en självständig nationell luthersk kyrka förbereddes och förverkligades. I avhandlingen synas även den lutherska missionen i Thailand i förhållande till samtida internationellt missionstänkande och strömningar inom den kristna världsmissionen. Slutligen sätts den lutherska missionen i Thailand in i en thailändsk kulturell och religiös kontext.

Knowledge Sharing between Generations in an Organisation - Retention of the Old or Building the New?

The study explores knowledge transfer between retiring employees and their successors in expert work. My aim is to ascertain whether there is knowledge development or building new knowledge related to this organisational knowledge transfer between generations; in other words, is the transfer of knowledge from experienced, retiring employees to their successors merely retention of the existing organisational knowledge by distributing it from one individual to another or does this transfer lead to building new and meaningful organisational knowledge. I call knowledge transfer between generations and the possibly related knowledge building in this study knowledge sharing between generations. The study examines the organisation and knowledge management from a knowledge-based and constructionist view. From this standpoint, I see knowledge transfer as an interactive process, and the exploration is based on how the people involved in this process understand and experience the phenomenon studied. The research method is organisational ethnography. I conducted the analysis of data using thematic analysis and the articulation method, which has not been used before in organisational knowledge studies. The primary empirical data consists of theme interviews with twelve employees involved in knowledge transfer in the organisation being studied and five follow-up theme interviews. Six of the interviewees are expert duty employees due to retire shortly, and six are their successors. All those participating in the follow-up interviews are successors of those soon to retire from their expert responsibilities. The organisation in the study is a medium-sized Finnish firm, which designs and manufactures electrical equipment and systems for the global market. The results of the study show that expert work-related knowledge transfer between generations can mean knowledge building which produces new, meaningful knowledge for the organisation. This knowledge is distributed in the organisation to all those that find it useful in increasing the efficiency and competitiveness of the whole organisation. The transfer and building of knowledge together create an act of knowledge sharing between generations where the building of knowledge presupposes transfer. Knowledge sharing proceeds between the expert and the novice through eight phases. During the phases of knowledge transfer the expert guides the novice to absorb the knowledge to be transferred. With the expert’s help the novice gradually comes to understand the knowledge and in the end he or she is capable of using it in his or her work. During the phases of knowledge building the expert helps the novice to further develop the knowledge being transferred so that it becomes new, useful knowledge for the organisation. After that the novice takes the built knowledge to use in his or her work. Based on the results of the study, knowledge sharing between generations takes place in interaction and ends when knowledge is taken to use. The results I obtained in the interviews by the articulation method show that knowledge sharing between generations is shaped by the novices’ conceptions of their own work goals, knowledge needs and duties. These are not only based on the official definition of the work, but also how the novices find their work or how they prioritise the given objectives and responsibilities. The study shows that the novices see their work primarily as maintenance or development. Those primarily involved in maintenance duties do not necessarily need knowledge defined as transferred between generations. Therefore, they do not necessarily transfer knowledge with their assigned experts, even though this can happen in favourable circumstances. They do not build knowledge because their view of their work goals and duties does not require the building of new knowledge. Those primarily involved in development duties, however, do need knowledge available from their assigned experts. Therefore, regardless of circumstances they transfer knowledge with their assigned experts and also build knowledge because their work goals and duties create a basis for building new knowledge. The literature on knowledge transfer between generations has focused on describing either the knowledge being transferred or the means by which it is transferred. Based on the results of this study, however, knowledge sharing between generations, that is, transfer and building is determined by how the novice considers his or her own knowledge needs and work practices. This is why studies on knowledge sharing between generations and its implementation should be based not only on the knowledge content and how it is shared, but also on the context of the work in which the novice interprets and shares knowledge. The existing literature has not considered the possibility that knowledge transfer between generations may mean building knowledge. The results of this study, however, show that this is possible. In knowledge building, the expert’s existing organisational knowledge is combined with the new knowledge that the novice brings to the organisation. In their interaction this combination of the expert’s “old” and the novice’s “new” knowledge becomes new, meaningful organisational knowledge. Previous studies show that knowledge development between the members of an organisation is the prerequisite for organisational renewal which in turn is essential for improved competitiveness. Against this background, knowledge building enables organisational renewal and thus enhances competitiveness. Hence, when knowledge transfer between generations is followed by knowledge building, the organisation kills two birds with one stone. In knowledge transfer the organisation retains the existing knowledge and thus maintains its competitiveness. In knowledge building the organisation developsnew knowledge and thus improves its competitiveness.

Liiketoimintaprosessien mittaaminen ja mallintaminen

Tutkimuksessa tutkitaan mallintamista ja mittaamista osana liiketoimintaproses-sien parantamista, sekä näiden asioiden kuvaamista soveltuvalla työkalulla. Ensin esitetään teoreettinen viitekehys siihen, kuinka prosesseja voidaan mitata ja mal-lintaa. Sitten raportoidaan käytännössä suoritettu kehitystyö, jolle on määritetty lähtö- ja tavoitetila. Työn onnistumista mitataan johtajahaastatteluin ja saatuja tuloksia verrataan teoriaan. Tutkimuksessa yhdistettiin analyyttinen mallinrakennus, tieteellinen ongelman-ratkaisutoiminta sekä konsultointi tarkoituksena saada aikaan kohde organisaati-olle sopiva konstruktio esitettyyn ongelmaan. Johtajahaastattelut analysoitiin ja suoritettiin kvalitatiivinen tarveanalyysi. Haastatteluja täydennettiin muulla kerä-tyllä aineistolla ja analyysin tarkkuutta pyritään kasvattamaan eri lähdeaineistojen ristivertailuilla. Yrityksissä on niin liiketoiminnalle elintärkeitä ydinprosesseja kuin niitä tukevia tukiprosessejakin. Niiden toiminta perustuu ennalta suunniteltuihin ja uudelleen-käytettäviin menetelmiin. Prosessit tulee sopeuttaa yrityksen arkkitehtuuriin ja niitä on jatkuvasti kehitettävä. Kehittäminen voidaan toteuttaa suurilla kertamuu-toksilla, jatkuvalla laadun parantamisella tai niiden yhdistelmänä. Mallintamisella ja mittaamisella on tärkeä tehtävä liiketoimintaprosessien kehit-tämisessä. Niiden avulla voidaan helpottaa erityisesti prosessien suunnittelua luomalla konkreettisia malleja ja mittareita prosesseista. Toteutuksessa käytettiin prototyyppilähestymistapaa ja työn onnistumista arvioivat yhtiön johtajat. Tutki-muksen tuloksia ovat eri tason prosessimallit, joiden luomisessa käytettiin eri mallintamistekniikoita, sekä mittaristot mittaamaan yrityksen tuottavuutta ja te-hokkuutta.

Käsityön monet merkitykset. Opettajankoulutuksen opiskelijoiden käsityölle antamat merkitykset ja niiden huomioon ottaminen käsityön opetuksessa

Tämän tutkimuksen kohteena olivat opettajaopiskelijat, jotka reflektoivat käsityöprosessin aikaista toimintaansa ja sen tuloksia. Tutkimuksen kontekstina oli Turun yliopiston opettajankoulutuslaitoksen Rauman yksikön käsityökasvatuksen perusopinnot. Tutkimushenkilöinä olivat KSP11b Yhteenvetojakson lukuvuosien 2007 – 2008 ja 2008 – 2009 käsityökasvatuksen sivuja pääaineopiskelijat (n=23). Tutkimusaineistona käytettiin opiskelijoiden KSP11b Yhteenvetojaksolla valmistamia käsityötuotteita, niihin liittyviä portfoliota sekä haastatteluita, jotka analysoitiin semioottisella sisällönanalyysilla. Tutkimuksen lähestymistapa on hermeneuttisfenomenologinen. Sen pyrkimyksenä on ymmärtää ja tulkita opiskelijoiden kokemia käsityöprosesseja ja niihin liitettyjä merkityksiä. Tutkimuksessa selvitettiin, millaisia merkityksiä opiskelijat antavat käsityölle ja miten käsityön merkitykset tulisi ottaa huomioon käsityön opetuksessa. Tutkimustuloksina esitetään opiskelijoiden käsityölle antamista merkityksistä neljä erilaista orientaatiotyyppiä: 1) käsityötuoteorientoituneet, 2) käsityötaitoorientoituneet 3) käsityöperinneorientoituneet ja 4) käsityöilmaisuorientoituneet. Käsityötuoteorientoituneet opiskelijat aloittavat ongelmanratkaisuprosessinsa päättämällä, minkä tuotteen he haluavat valmistaa. Käsityötaitoorientoituneille opiskelijoille käsityöprosessi on oman osaamisen näyttämistä ja kehittämistä. Käsityöperinneorientoituneet opiskelijat saavat motivaationsa käsityötuotteen valmistukseen käsityöperinteen vaalimisesta, esimerkiksi halusta oppia perinteisiä käsityötekniikoita tai halusta oppia käsitöitä jonkun läheisen henkilön ohjaamana. Käsityöilmaisuorientoituneet opiskelijat suhtautuvat käsityöprosessiin elämyksellisesti, jolloin prosessi perustuu tekijän kokemuksiin, mielikuviin, muistojen vaalimiseen ja tunteiden ilmaisemiseen sekä identiteetin rakentamiseen. Tutkimuksessa selvitettiin lisäksi käsityön merkitysten mahdollisuuksia käsityön opetuksessa. Nämä käsityön opetuksen näkökulmat on tutkimuksessa jaettu viiteen luokkaan: 1) käsityötaidon kehittäminen, 2) kokonaisen käsityön tekeminen, 3) konkreettisen käsityötuotteen valmistaminen, 4) käsityöilmaisun kehittäminen ja 5) käsityön monipuoliset sisällöt. Tässä tutkimuksessa korostuu, että käsityön opetus perustuu käsityötaidon oppimiseen. Käsityötaidon kehittämiseen liittyy käsityöllisesti työstettävien materiaalien ja niiden ominaisuuksien hallintaa ja muokkaamiseen tarvitaan käsityöteknologiaa, henkilökohtaista käsityötaitoa ja laatutietoisuutta. Käsityötuote on käsityöprosessin lopputuloksena syntyvä konkreettinen tuotos. Käsityöprosessi toteutuu kokonaisena käsityönä, jossa tekijä suunnittelee ja toteuttaa itse suunnitelmansa. Kokonainen käsityö saa eri tekijöillä erilaisia sovelluksia. Käsityöilmaisulla tarkoitetaan tekijän henkilökohtaista sitoutumista prosessiin ja käsityön monipuolisilla sisällöillä materiaaleja ja teknologioita, joita käsityön tekijä käyttää käsityöprosessin aikana. Lisäksi tutkimusaineistossa ilmeni, että opiskelijat sitoutuvat käsityöprosessiin, kun heillä on mahdollisuus ilmaista itselleen tärkeitä, henkilökohtaisia asioitaan, kuten omaa elämäntilannettaan ja merkityksellisiä kokemuksiaan.

Lämpötila-anturit betonielementeissä

Yleinen tapa betonin kuivumisnopeuden mittaamiseen on käyttää pieniä testivaluja kuivumisen arvioimiseen. Tälle epätarkalle tekniikalle olisi hyvä löytää korvaaja. Tässä kandidaatintyössä tutkitaan soveltuvatko lämpötila-anturilliset RFID-tunnisteet betonin kuivumisnopeuden mittaamiseen ja onko tällä tekniikalla potentiaalia syrjäyttää vanhat toimintatavat. Tämän lisäksi työssä tutkitaan laajemmin RFID-tekniikan ja erityisesti anturillisten RFID-tunnisteiden hyödyntämistä rakennusteollisuudessa. RFID-tekniikka soveltuu moniin rakennusteollisuuden käyttökohteisiin, kuten tiedon hallinnointiin ja rakenteiden kunnon seurantaan. Erilaisten elementtien, materiaalien, työkalujen yms. identifioinnilla pystytään saavuttamaan selkeitä hyötyjä ja RFID on oiva työkalu tähän. Rakenteiden kunnon seurannassa on yleistä käyttää anturiverkkoja. Näiden osalta yleisempää on käyttää langallisia verkkoja, mutta langattomuus on yleistymässä näissäkin. RFID tarjoaa myös näiden osalta uusia hyötyjä. Lämpötila-anturilliset RFID-tunnisteet soveltuvat hyvin betonin kuivumisnopeuden mittaamiseen. Tunnisteiden avulla lämpötila pystytään mittaamaan betonin sisältä. Sisäinen lämpötilan avulla betonin kuivumisnopeus pystytään määrittämään tarkemmin. Tämä tekniikka on myös nopeampi ja edullisempi kuin vanhat toimintatavat.

Future trends of Finnish cement based construction

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.

Building object-oriented software with the D-Bus messaging system

Object-oriented programming is a widely adopted paradigm for desktop software development. This paradigm partitions software into separate entities, objects, which consist of data and related procedures used to modify and inspect it. The paradigm has evolved during the last few decades to emphasize decoupling between object implementations, via means such as explicit interface inheritance and event-based implicit invocation. Inter-process communication (IPC) technologies allow applications to interact with each other. This enables making software distributed across multiple processes, resulting in a modular architecture with benefits in resource sharing, robustness, code reuse and security. The support for object-oriented programming concepts varies between IPC systems. This thesis is focused on the D-Bus system, which has recently gained a lot of users, but is still scantily researched. D-Bus has support for asynchronous remote procedure calls with return values and a content-based publish/subscribe event delivery mechanism. In this thesis, several patterns for method invocation in D-Bus and similar systems are compared. The patterns that simulate synchronous local calls are shown to be dangerous. Later, we present a state-caching proxy construct, which avoids the complexity of properly asynchronous calls for object inspection. The proxy and certain supplementary constructs are presented conceptually as generic object-oriented design patterns. The e ect of these patterns on non-functional qualities of software, such as complexity, performance and power consumption, is reasoned about based on the properties of the D-Bus system. The use of the patterns reduces complexity, but maintains the other qualities at a good level. Finally, we present currently existing means of specifying D-Bus object interfaces for the purposes of code and documentation generation. The interface description language used by the Telepathy modular IM/VoIP framework is found to be an useful extension of the basic D-Bus introspection format.
