The purpose of the work was to realize a high-speed digital data transfer system for RPC muon chambers in the CMS experiment on CERN’s new LHC accelerator. This large scale system took many years and many stages of prototyping to develop, and required the participation of tens of people. The system interfaces to Frontend Boards (FEB) at the 200,000-channel detector and to the trigger and readout electronics in the control room of the experiment. The distance between these two is about 80 metres and the speed required for the optic links was pushing the limits of available technology when the project was started. Here, as in many other aspects of the design, it was assumed that the features of readily available commercial components would develop in the course of the design work, just as they did. By choosing a high speed it was possible to multiplex the data from some the chambers into the same fibres to reduce the number of links needed. Further reduction was achieved by employing zero suppression and data compression, and a total of only 660 optical links were needed. Another requirement, which conflicted somewhat with choosing the components a late as possible was that the design needed to be radiation tolerant to an ionizing dose of 100 Gy and to a have a moderate tolerance to Single Event Effects (SEEs). This required some radiation test campaigns, and eventually led to ASICs being chosen for some of the critical parts. The system was made to be as reconfigurable as possible. The reconfiguration needs to be done from a distance as the electronics is not accessible except for some short and rare service breaks once the accelerator starts running. Therefore reconfigurable logic is extensively used, and the firmware development for the FPGAs constituted a sizable part of the work. Some special techniques needed to be used there too, to achieve the required radiation tolerance. The system has been demonstrated to work in several laboratory and beam tests, and now we are waiting to see it in action when the LHC will start running in the autumn 2008.

This study examines how to institutional environment of gambling is currently in motion both in Europe and Finland. Furthermore, it examines the criticism by Finnish professional sport clubs directed towards the national gambling monopolies, especially Veikkaus Oy. This criticism addresses the acclaimed issue of low or non-existing sponsorship funds coming to the clubs despite the clubs’ duties to promote Veikkaus Oy in their stadiums etc. In essence the main research objective was to examine the interaction and institutional environments of both Finnish professional sport clubs and gambling regulation. This was done through three sub-objectives: 1) to analyze professional sport as business and its institutional environment 2) to analyze the institutions of gambling in their current state and their potential future 3) to evaluate the potential impact of an institutional change in gambling legislation to the professional sport clubs The findings from Finland were then compared to those of Denmark where an institutional change had occurred in gambling regulation. Empirical data was collected through multiple interviews. Interviewees represented sport clubs (7), sport association (1), sport league (1), Finnish monopoly representatives (2), commercial gambling providers (1), Danish monopoly system representatives (1), Danish sport club (1). In addition a vast amount of secondary data (e.g. Green and white books by EU, court decisions, a variety of studies etc.). Theoretically this study combines the aspects of institutional theory with the theory of professional sports as business. This proved to be a rather new approach and no published literature was found to have done specifically this. The findings of this study are twofold, on the European level it is clear that the momentum if towards a more liberated gambling market while Finland is at the moment trying to go the opposite direction and uphold its monopoly. From the sport club’s level the findings suggest that currently sport clubs do not directly benefit from the funds originated from Veikkaus Oy as these funds are more or less used on the association/league levels. However, the clubs themselves are also lacking in self-criticism as they are lacking in clear sponsorship packages/programs which Veikkaus Oy might be interested in participating. If liberation of the gambling market would occur it is highly possible that that the largest clubs in football and ice-hockey would be the main beneficiaries while smaller clubs and sports could possibly be worse off than currently. These interpretations were well supported by the findings from Denmark.

Tämän diplomityö käsittelee UPM-Kymmenen paperitoimialoilla käynnissä olevaa Chain 2000 –projektin toteutusta uuden markkinan integroinnin aikana SAP –toiminnanohjausjärjestelmään yhden paperitehtaan näkökulmasta. Koska tehdasjärjestelmän kaikkien osa-alueiden integraatio on erittäin vaativa ja pitkäkestoinen prosessi, keskittyy tämä työ yhden markkinan integraatioon. Tavoitteena on suunnitella, toteuttaa ja testata tässä integroinnissa tarvittavat järjestelmämuutokset ja kuvata integroinnissa käytettäviä työkaluja, toimintamalleja ja prosesseja. Samalla kerrotaan tämän vaativan projektin mukanaan tuomia ongelmia ja ratkaisuja yhden paperitehtaan kannalta. Työssä esitellään erilaisia keinoja ja työkaluja varsinkin IT -projektien hallinnointiin ja toteuttamiseen sekä käydään läpi ohjelmistotestaaminen, ERP -järjestelmät ja tietovarastot. Työ tuo esille miten haastavaa globaalin IT –projektin toteuttaminen on. Tarkastelun tuloksena huomataan, että standardityökalujen käyttö aiheuttaa ongelmia erikoistilanteissa ja väärä informaatio tuo yritykselle ylimääräisiä kustannuksia. Projektin myötä toimintojen toteutuksen painotus ja samalla vastuu tiedon oikeellisuudesta siirtyy jatkuvasti tehtaalle päin. Integraatiotestaamisesta ja tarvittavista muutoksista on diplomityön aikana selviydytty kiitettävästi, mutta täysi varmuus kaikkien integraatioon osallistuvien järjestelmien toimivuudesta saadaan vasta itse käyttöönotossa kesällä 2004. Ylläpito käyttöönoton jälkeen vaatii myös resursseja.

Tutkimuksen päätavoitteena oli tutkia miten suomalaiset suuret pörssiyritykset ulkoisesti varmentavat yhteiskuntavastuuraporttinsa. Lisäksi tavoitteena oli tutkia miten yritykset arvioivat varmentamisen vaikuttavan raporttien luotettavuuteen. Työn teorian muodosti kansainväliset ja kotimaiset kirjat ja artikkelit. Empiirinen aineisto kerättiin yritysten yhteiskuntavastuuraporteista, yritysten internetsivuilta ja haastatteluilla. Teemahaastatteluja tehtiin neljälle yrityksen edustajalle ja kahdelle tilintarkastusyhteisön ulkoi-selle varmentajalle. Tutkimusmenetelmä oli kvalitatiivinen ja kuvaileva. Yhteiskuntavastuun huomioiminen ja siitä raportoiminen on yleistynyt Suomessa ja maailmalla 2000-luvulla. Yritykset koetaan tänä päivänä merkittäviksi tekijöiksi yhteiskunnassa ja näin ollen yrityksiltä vaaditaan vastuullista ja ehdottoman luotettavaa toimintaa. Vastuun kantamista vaa-ditaan erityisesti kansainvälisiltä yrityksiltä. Sidosryhmät odottavat yritysten yhteiskuntavastuuraporttien tarjoavan luotettavaa tietoa päätöksenteon tueksi. Luotettavuuden ja uskottavuuden lisäämiseksi, jotkut yritykset ovat alkaneet käyttää yhteiskuntavastuuraporttien ulkoista varmennusta. Ulkoisella varmentamisella tarkoitetaan sellaista toimintaa, jossa kolmas riip-pumaton taho varmentaa yrityksen ei-taloudellisen raportin.

Songs have the power to get through to people. When lyrics are combined with a tune, the result is an entity where the first few notes of a melody can evoke emotions of recognition and belonging. A song treasury consists of such songs that are part of a canonized song tradition. The process where certain songs become part of an established song treasury is long, and many other aspects than the tune itself influence the forming of a song treasury. By examining the characteristics of a song tradition, the history of an ethnic group can be illuminated. In this study, music, pedagogy, and the sociocultural context are merged into a whole where a common song tradition, the song treasury, is in focus. The main aim of this study is to deepen the understanding of a song treasury, its development and contents. This understanding is accomplished by analyzing the musical and lyrical characteristics of 60 songs, which have been sung in schools, homes, and communities, thereby becoming popular among the Swedish-speaking Finns during the 20th century. The songs have been chosen by combining three song lists, of which two lists are closely related to school curricula. The third song list is a result of a survey on favourite songs, according to the situation around year 2000. The songs are examined in their notated versions, a number of song books and text books (n = 29) forming the empirical material. In this study, a hermeneutical approach is applied, content analysis being the method. The analysis is based on three perspectives: the sociocultural perspective, the music-pedagogical perspective, and the musico-analytical perspective. Within each perspective, two aspects are studied. This results in a hexagonal model which forms the structure of the study as a whole. The first two perspectives form the background; a historical context where nation, education, home country, and homestead are regarded as highly important. A common song repertoire is considered to be an effective means of building collective identity within ethnic groups, the common language and the cultural heritage being used as rhetorical arguments. During the early 1900s, choir festivals become an educational platform where conceptions of a common belonging are developed and strengthened through religious, patriotic, and poetical expressions. National school curricula in singing and music have similar characteristics, cultural heritage and values education being in focus. The song lyrics often describe nature and emotions, and they also appear to be personal and situated in a given time and place. Patriotic expressions and songs about music are also fairly common. The songs generally express positive attitudes, which are intensified by major tonality, rich and varied melodies with stable rhythms, and a strong tonal base. The analyzed details of the studied aspects are merged into a thick description, which results in an interpretation pattern with three dimensions: a song treasury can be considered an expression of collective identity, cultural heritage, and values education.

Coastal areas harbour high biodiversity, but are simultaneously affected by rapid degradations of species and habitats due to human interactions. Such alterations also affect the functioning of the ecosystem, which is primarily governed by the characteristics or traits expressed by the organisms present. Marine benthic fauna is nvolved in numerous functions such as organic matter transformation and transport, secondary production, oxygen transport as well as nutrient cycling. Approaches utilising the variety of faunal traits to assess benthic community functioning have rapidly increased and shown the need for further development of the concept. In this thesis, I applied biological trait analysis that allows for assessments of a multitude of categorical traits and thus evaluation of multiple functional aspects simultaneously. I determined the functional trait structure, diversity and variability of coastal zoobenthic communities in the Baltic Sea. The measures were related to recruitment processes, habitat heterogeneity, large-scale environmental and taxonomic gradients as well as anthropogenic impacts. The studies comprised spatial scales from metres to thousands of kilometres, and temporal scales spanning one season as well as a decade. The benthic functional structure was found to vary within and between seagrass landscape microhabitats and four different habitats within a coastal bay, in papers I and II respectively. Expressions of trait categories varied within habitats, while the density of individuals was found to drive the functional differences between habitats. The findings in paper III unveiled high trait richness of Finnish coastal benthos (25 traits and 102 cateogries) although this differed between areas high and low in salinity and human pressure. In paper IV, the natural reduction in taxonomic richness across the Baltic Sea led to an overall reduction in function. However, functional richness in terms of number of trait categories remained comparatively high at low taxon richness. Changes in number of taxa within trait categories were also subtle and some individual categories were maintained or even increased. The temporal analysis in papers I and III highlighted generalities in trait expressions and dominant trait categories in a seagrass landscape as well as a “type organism” for the northern Baltic Sea. Some initial findings were made in all four papers on the role of common and rare species and traits for benthic community functioning. The findings show that common and rare species may not always express the same trait categories in relation to each other. Rare species in general did not express unique functional properties. In order to advance the understanding of the approach, I also assessed some issues concerning the limitations of the concept. This was conducted by evaluating the link between trait category and taxonomic richness using especially univariate measures. My results also show the need to collaborate nationally and internationally on safeguarding the utility of taxonomic and trait data. The findings also highlight the importance of including functional trait information into current efforts in marine spatial planning and biomonitoring.

Tässä tutkimuksessa tarkastellaan aineellista modernia ja materiaalisen kulttuurin muutosta Suomessa 1880-luvulta 1940-luvulle tutkimalla sitä, miten kolme kansainvälistä teknologiaa, gramofoni, polkupyörä ja valokuvaus, otettiin Suomessa käyttöön ja millaisia paikallisia ilmiöitä niiden ympärille kehittyi. Tutkimus koostuu johdanto- ja yhteenveto-osan lisäksi kuudesta artikkelista, joissa käsitellään seuraavia alateemoja: itse tehtyjä polkupyöriä, käyntikorttikuvien käyttöä maalaiskodeissa, maaseudun pyöräilyä ja sen muistelemista, vuoden 1929 gramofonikuumetta, valokuvausta teknisenä harrastuksena sekä maalaisia gramofonin käytön tapoja. Tutkimuksen lähteinä on käytetty laajoja muistitietoaineistoja, sanoma- ja aikakauslehtiaineistoja, arkistoaineistoja, aikalaiskirjallisuutta ja museoesineitä. Lähteistä on etsitty mikrohistoriallista lukutapaa noudattaen johtolankoja gramofoniin, polkupyörään ja valokuvaukseen liittyneihin käytäntöihin. Esitän, että muistitietolähteet, muiden lähteiden kanssa ristiinluettuina, antavat hyvän mahdollisuuden sellaisten arjen käytäntöjen tarkasteluun, joiden tutkiminen muiden lähteiden perusteella olisi vaikeaa tai mahdotonta. Tutkimuksessa käytetyistä teoreettisista kehyksistä niin teknologian sosiaalinen rakentuminen, arjen historia, materiaaliseen kulttuuriin liittyvä teoriapohja, kulutuskulttuurin tutkimus kuin käytäntöteoriatkin kannustavat tarkastelemaan sitä, miten käyttäjien toiminta muokkaa ja määrittää teknologiaa. Näiden teoriasuuntausten pohjalta olen tätä tutkimusta varten kehittänyt itse tehdyn modernin ja kansankeksinnön käsitteet, jotka tarkentavat katseen ajallisesti ja paikallisesti tyypillisiin teknologian muokkauksen ja määrittelyn tapoihin sekä paikalliseen teknologiseen kekseliäisyyteen. Itse tehdyn modernin käsite auttaa hahmottamaan materiaalisia muutoksia ja pysyvyyksiä ajanjaksolla 1800-luvun lopulta toiseen maailmansotaan. Suomalaiset muovasivat omanlaisensa modernin, jossa uutuudet ja muutokset sulautuivat osaksi sitkeinä jatkuvia ja hitaasti muuttuvia maalaisyhteiskunnan toimintatapoja ja muokkasivat niitä vähitellen. Itse tehty moderni sekoitti omavaraisuutta ja kulutuskulttuuria, käsillä tekemiseen perustuvaa taitavuutta ja kursseilla sekä koulutuksessa saavutettua teknistä tietoa, paikallisia aineksia ja kansainvälisiä vaikutteita. Puhumalla kansanomaisista keksinnöistä olen halunnut korostaa tällaisten yhdistelmien mahdollisuutta ruohonjuuritasolla ja massatuotettujen laitteiden sovittamista osaksi pitkälti itse tehtyä ja omavaraista esinemaailmaa.

This thesis studies the possibility to use lean tools and methods in a quotation process which is carried out in an office environment. The aim of the study was to find out and test the relevant lean tools and methods which can help to balance and standardize the quotation process, and reduce the variance in quotation lead times and in quality. Seminal works, researches and guide books related to the topic were used as the basis for the theory development. Based on the literature review and the case company’s own lean experience, the applicable lean tools and methods were selected to be tested by a sales support team. Leveling production, by product categorization and value stream mapping, was a key method to be used to balance the quotation process. 5S method was started concurrently for standardizing the work. Results of the testing period showed that lean tools and methods are applicable in office process and selected tools and methods helped to balance and standardize the quotation process. Case company’s sales support team decided to implement new lean based quotation process model.

Tutkimuksessa keskitytään tutkimaan kuluttamista elämäntavan ja identiteetin muovaajana yhden yksilön elämän kautta. Kuluttamista tutkitaan statuskuluttamisen (conspicious consumption), tilallisuuden ja sukupuolihistorian käsitteistöä hyväksi käyttäen. Tutkimuksen lähteinä on käytetty liikekirjeitä ja tilikirjoja, yksityistä kirjeenvaihtoa, päiväkirjoja ja sanomalehtiä sekä aikalaismuistelmia. Naista lähdemateriaaleista on koottu sekä tilastollista aineistoa että kvalitatiivista, lähilukuun ja mikrohistorialliseen tutkimusotteeseen nojautuvaa tutkimusta. Tutkimus alkaa vuodesta 1799 ja päättyy 1830-luvulle, jolloin seuraava sukupolvi otti vastuun liiketoimista ja lähdeaineistossa tapahtui muutoksia kuluttamisen kirjaamisen suhteen. Tutkimuksen keskeiset käsitteet ovat statuskuluttaminen ja identiteetti. Näitä käsitteitä lähestytään Thorstein Veblenin, Norbert Eliaksen ja Pierre Bourdieun tutkimuksia apuna käyttäen. Tutkimus käsittelee erottautumisen ja jäljittelyn tematiikkaa merkittävimpänä kuluttamisen motivaattoreina. Lisaksi tutkimus nostaa esille hyvän maun ja muodinmukaisuuden kulutusvalintojen taustalla. Statuskuluttaminen kytkeytyy sosiaaliseen kanssakäymiseen. Kuluttamisen kohteet ovat esineitä ja asioita, joita pidetään esillä seurapiireissä. Kuluttaminen tapahtuu seuraelämän ehdoilla, sen mukavoittamiseksi, aseman osoittamiseksi seurapiireissä tai sosiaalisen paineen vuoksi. Tutkimus osoittaa kotitalouden merkityksen kuluttamisen paikkana ja kohteena. Tutkimus myös osoittaa naisten toimintakentän olleen kytköksissä kotitalouden asemaan yhteisössään sekä osoittaa, että sukupuolta pitää tarkastella suhteessa yksilön sosiaaliseen asemaan. Tutkimus osoittaa, että Marie Hackmanin kuluttaminen muuttui ikääntymisen myötä. Aseman osoittaminen oli merkittävämpää nuorena ja aseman ollessa vielä vakiintumattomampi.

A business model is a structure frame of an organization that can bring significant benefits and competitive advantage when structured properly. The aim of this paper was to observe and describe development of business models’ and identify factors and elements of a business model that are in a key role from the perspective of an organizational sustainability. One is striving to bring out in this thesis how should truly sustainable business model look like and what are main characteristics of it. Additionally, some recommendations that could be helpful in order to build sustainable and balanced business model in a company are presented in this work. The meaning was to make theoretical and in some extent practical acquaintance with such new business models as open business model and sustainable business model. Long-term sustainability achievement in a company was in a centric role and used as a main criteria when constructing sustainable business model structure. The main research question in this study aims to answer: What a firm should consider in order to develop profitable and sustainable business model? This study is qualitative in nature and it was conducted using content analyze as a main method of this research. The perspective of the target data in this study is an outlook of its producers of how sustainability is reached in an organization throw business model and which practices are important and has to be taken into account. The material was gathered mainly from secondary sources and the theoretical framework was outright built based on secondary data. The secondary data that have been mostly dissertations, academic writings, cases, academic journals and academic books have been analyzed from the point of view of sustainability perspective. As a result it became evident that a structure of a business model and its implementation along with a strategy is often what leads companies to success. However, for the most part, overall business environment decides and delimits how the most optimal business model should be constructed in order to be effective and sustainable. The evaluation of key factors and elements in business model leading organization to sustainability should be examined throw triple bottom line perspective, where key dimensions are environmental, social and economic. It was concluded that dimensions should be evaluated as equal in order to attain total long lasting sustainability, contradicting traditional perspective in business where profit production is seen as only main goal of a business.

Personalized medicine will revolutionize our capabilities to combat disease. Working toward this goal, a fundamental task is the deciphering of geneticvariants that are predictive of complex diseases. Modern studies, in the formof genome-wide association studies (GWAS) have afforded researchers with the opportunity to reveal new genotype-phenotype relationships through the extensive scanning of genetic variants. These studies typically contain over half a million genetic features for thousands of individuals. Examining this with methods other than univariate statistics is a challenging task requiring advanced algorithms that are scalable to the genome-wide level. In the future, next-generation sequencing studies (NGS) will contain an even larger number of common and rare variants. Machine learning-based feature selection algorithms have been shown to have the ability to effectively create predictive models for various genotype-phenotype relationships. This work explores the problem of selecting genetic variant subsets that are the most predictive of complex disease phenotypes through various feature selection methodologies, including filter, wrapper and embedded algorithms. The examined machine learning algorithms were demonstrated to not only be effective at predicting the disease phenotypes, but also doing so efficiently through the use of computational shortcuts. While much of the work was able to be run on high-end desktops, some work was further extended so that it could be implemented on parallel computers helping to assure that they will also scale to the NGS data sets. Further, these studies analyzed the relationships between various feature selection methods and demonstrated the need for careful testing when selecting an algorithm. It was shown that there is no universally optimal algorithm for variant selection in GWAS, but rather methodologies need to be selected based on the desired outcome, such as the number of features to be included in the prediction model. It was also demonstrated that without proper model validation, for example using nested cross-validation, the models can result in overly-optimistic prediction accuracies and decreased generalization ability. It is through the implementation and application of machine learning methods that one can extract predictive genotype–phenotype relationships and biological insights from genetic data sets.
