Perspectives interculturelles et interlinguistiques sur le discours académique – Crosscultural and Crosslinguistic Perspectives on Academic Discourse. Volume 1

The Department of French Studies of the University of Turku (Finland) organized an International Bilingual Conference on Crosscultural and Crosslinguistic Perspectives on Academic Discourse from 2022 May 2005. The event hosted specialists on Academic Discourse from Belgium, Finland, France, Germany, Italy, Norway, Spain, and the USA. This book is the first volume in our series of publications on Academic Discourse (AD hereafter). The following pages are composed of selected papers from the conference and focus on different aspects and analytical frameworks of Academic Discourse. One of the motivations behind organizing the conference was to examine and expand research on AD in different languages. Another one was to question to what extent academic genres are culturebound and language specific or primarily field or domain specific. The research carried out on AD has been mainly concerned with the use of English in different academic settings for a long time now – mainly written contexts – and at the expense of other languages. Alternatively the academic genre conventions of English and English speaking world have served as a basis for comparison with other languages and cultures. We consider this first volume to be a strong contribution to the spreading out of researches based on other languages than English in AD, namely Finnish, French, Italian, Norwegian and Romanian in this book. All the following articles have a strong link with the French language: either French is constitutive of the AD corpora under examination or the article was written in French. The structure of the book suggests and provides evidence that the concept of AD is understood and tackled to varying degrees by different scholars. Our first volume opens up the discussion on what AD is and backs dissemination, overlapping and expansion of current research questions and methodologies. The book is divided into three parts and contains four articles in English and six articles in French. The papers in part one and part two cover what we call the prototypical genre of written AD, i.e. the research article. Part one follows up on issues linked to the 13 Research Article (RA hereafter). Kjersti Fløttum asks wether a typical RA exists and concentrates on authors’ voices in RA (self and other dimensions), whereas Didriksen and Gjesdal’s article focuses on individual variation of the author’s voice in RA. The last article in this section is by Nadine Rentel and deals with evaluation in the writing of RA. Part two concentrates on the teaching and learning of AD within foreign language learning, another more or less canonical genre of AD. Two aspects of writing are covered in the first two articles: foreign students’ representations on rhetorical traditions (Hidden) and a contrastive assessment of written exercices in French and Finnish in Higher Education (Suzanne). The last contribution in this section on AD moves away from traditional written forms and looks at how argumentation is constructed in students’ oral presentations (Dervin and Fauveau). The last part of the book continues the extension by featuring four articles written in French exploring institutional and scientific discourses. Institutional discourses under scrutiny include the European Bologna Process (Galatanu) and Romanian reform texts (Moilanen). As for scientific discourses, the next paper in this section deconstructs an ideological discourse on the didactics of French as a foreign language (Pescheux). Finally, the last paper in part three reflects on varied forms of AD at university (Defays). We hope that this book will add some fuel to continue discussing diverse forms of and approches to AD – in different languages and voices! No need to say that with the current upsurge in academic mobility, reflecting on crosscultural and crosslinguistic AD has just but started.

Towards combining interactive mobile TV and smart spaces : architectures, tools and application development

Technological developments in microprocessors and ICT landscape have made a shift to a new era where computing power is embedded in numerous small distributed objects and devices in our everyday lives. These small computing devices are ne-tuned to perform a particular task and are increasingly reaching our society at every level. For example, home appliances such as programmable washing machines, microwave ovens etc., employ several sensors to improve performance and convenience. Similarly, cars have on-board computers that use information from many di erent sensors to control things such as fuel injectors, spark plug etc., to perform their tasks e ciently. These individual devices make life easy by helping in taking decisions and removing the burden from their users. All these objects and devices obtain some piece of information about the physical environment. Each of these devices is an island with no proper connectivity and information sharing between each other. Sharing of information between these heterogeneous devices could enable a whole new universe of innovative and intelligent applications. The information sharing between the devices is a diffcult task due to the heterogeneity and interoperability of devices. Smart Space vision is to overcome these issues of heterogeneity and interoperability so that the devices can understand each other and utilize services of each other by information sharing. This enables innovative local mashup applications based on shared data between heterogeneous devices. Smart homes are one such example of Smart Spaces which facilitate to bring the health care system to the patient, by intelligent interconnection of resources and their collective behavior, as opposed to bringing the patient into the health system. In addition, the use of mobile handheld devices has risen at a tremendous rate during the last few years and they have become an essential part of everyday life. Mobile phones o er a wide range of different services to their users including text and multimedia messages, Internet, audio, video, email applications and most recently TV services. The interactive TV provides a variety of applications for the viewers. The combination of interactive TV and the Smart Spaces could give innovative applications that are personalized, context-aware, ubiquitous and intelligent by enabling heterogeneous systems to collaborate each other by sharing information between them. There are many challenges in designing the frameworks and application development tools for rapid and easy development of these applications. The research work presented in this thesis addresses these issues. The original publications presented in the second part of this thesis propose architectures and methodologies for interactive and context-aware applications, and tools for the development of these applications. We demonstrated the suitability of our ontology-driven application development tools and rule basedapproach for the development of dynamic, context-aware ubiquitous iTV applications.

Identification and validation of novel prostate cancer biomarkers

Prostate cancer (PCa) has emerged as the most commonly diagnosed lethal cancer in European men. PCa is a heterogeneous cancer that in the majority of the cases is slow growing: consequently, these patients would not need any medical treatment. Currently, the measurement of prostate-specific antigen (PSA) from blood by immunoassay followed by digital rectal examination and a pathological examination of prostate tissue biopsies are the most widely used methods in the diagnosis of PCa. These methods suffer from a lack of sensitivity and specificity that may cause either missed cancers or overtreatment as a consequence of over-diagnosis. Therefore, more reliable biomarkers are needed for a better discrimination between indolent and potentially aggressive cancers. The aim of this thesis was the identification and validation of novel biomarkers for PCa. The mRNA expression level of 14 genes including AMACR, AR, PCA3, SPINK1, TMPRSS2-ERG, KLK3, ACSM1, CACNA1D, DLX1, LMNB1, PLA2G7, RHOU, SPON2, and TDRD1 was measured by a truly quantitative reverse transcription PCR in different prostate tissue samples from men with and without PCa. For the last eight genes the function of the genes in PCa progression was studied by a specific siRNA knockdown in PC-3 and VCaP cells. The results from radical prostatectomy and cystoprostatectomy samples showed statistically significant overexpression for all the target genes, except for KLK3 in men with PCa compared with men without PCa. Statistically significant difference was also observed in low versus high Gleason grade tumors (for PLA2G7), PSA relapse versus no relapse (for SPON2), and low versus high TNM stages (for CACNA1D and DLX1). Functional studies and siRNA silencing results revealed a cytotoxicity effect for the knock-down of DLX1, PLA2G7, and RHOU, and altered tumor cell invasion for PLA2G7, RHOU, ACSM1, and CACNA1D knock-down in 3D conditions. In addition, effects on tumor cell motility were observed after silencing PLA2G7 and RHOU in 2D monolayer cultures. Altogether, these findings indicate the possibility of utilizing these new markers as diagnostic and prognostic markers, and they may also represent therapeutic targets for PCa.

Suorituskyvyn analysointi ja mittaaminen julkisella sektorilla

Suorituskyvyn mittaamiselle ja seurannalle on nykyisin laajaa tarvetta myös julkisella sektorilla. Tutkimuksen tarkoituksena oli kehittää soveltuvia suorituskykyä kuvaavia mittareita ja rakentaa niistä käyttökelpoinen suorituskyvyn analysointijärjestelmä julkisen sektorin käyttöön. Ensisijaisena lähtökohtana olivat fyysiset mittarit, koska ne soveltuvat paremmin julkisen sektorin toimintaympäristöön.Tutkimuksen teoriaosassa esitetään joitakin suorituskyvyn analysointijärjestelmiä. Julkiselle sektorille soveliaina viitekehyksinä esitellään yleisellä tasolla balanced scorecard, suorituskykypyramidi, benchmarking, dynaaminen suorituskyvyn mittausjärjestelmä, laatupalkintokriteeristö, SAKE-sovellus ja suorituskykymatriisi.Työssä paneudutaan melko laajalti tekijöihin, joilla on voimakas vaikutus suorituskykyyn. Tällaisia tekijöitä ovat laatuasiat, tuottavuus ja organisaation kilpailukyvykkyys.Tutkimuksen käytännön osassa rakennettiin suorituskyvyn analysointi- ja mittausjärjestelmä. Ensin määriteltiin mittausjärjestelmään soveliaat suorituskyvyn osa-alueet ja seuraavaksi mittarit. Taloudellisia mittareita kehitettiin vain muutama, sillä pääpaino mittarien kehittelyssä olivat ei-taloudelliset mittarit. Mittaristo auttaa organisaatiota mittaamaan sen tilannetta matkalla jatkuvan parantamisen tiellä.

Suomalaisen rahastosijoittajan profiili

Tutkimuksen tarkoituksena on luoda suomalaisen rahastosijoittajan profiili. Tutkimuskohteena ovat sijoittajien demografiset ominaisuudet, rahastosijoitukset sekä rahastotransaktiot. Aineistona on erään suomalaisen rahastoyhtiön henkilöasiakastietokanta vuosilta 1998 - 2003. Tutkimustulosten mukaan rahastosijoittaminen on yleistynyt Suomessa viime vuosien aikana. Erityisesti naisten määrä rahastosijoittajien joukossa on kasvussa. Rahastosijoitusten suuruus riippuu sijoittajan iästä sekä sukupuolesta. Mitä vanhempi sijoittaja on, sitä enemmän hän on sijoittanut rahastoihin. Lisäksi miehet sijoittavat suurempia summia kuin naiset. Viimeisten kolmen vuoden aikana suomalaisten rahastosijoittajien sijoituskohteiden painopiste on muuttunut riskillisemmistä rahastoista vähäriskisiin rahastoihin, erityisesti lyhyen koron rahastoihin. Osakemarkkinoiden mennyt kehitys vaikuttaa sijoituspäätöksiin. Rahastosijoittajien markkina-ajoituskyky on kuitenkin melko heikko. Miehet tekevät aktiivisemmin merkintöjä ja lunastuksia ja lisäksi reagoivat naisia nopeammin markkinoiden muutoksiin.

Asiakkuuksien strateginen arvottaminen ja luokittelu

Tämän tutkimuksen kohdeorganisaatio on suuren teollisuusyrityksen sisäinen raaka-aineen hankkija ja toimittaja. Tutkimuksessa selvitetään, mistä kohdeorganisaation hankinta-asiakkuuksien arvo muodostuu ja kuinka olemassa olevan liiketoimintadatan perusteella voidaan tutkia, arvioida ja luokitella kauppojen ja asiakkuuksien arvokkuutta aikaan sitomatta, objektiivisesti ja luotettavasti. Tutkimuksen teoriaosiossa esitellään lähestymistapoja ja menetelmiä, joiden avulla voidaan jalostaa olemassa olevasta datasta uutta sidosryhmätietämystä liiketoiminnan käyttöön, sekä tarkastellaan asiakaskannattavuusanalyysin, portfolioanalyysin, sekä asiakassegmentoinnin perusteita ja malleja. Näiden teorioiden ja mallien pohjalta rakennetaan kohdeorganisaatiolle räätälöity, indeksoituihin hinta-, määrä- ja kauppojen toistuvuus-muuttujiin perustuva, asiakkuuksien arvottamis- ja luokittelumalli. Arvottamis- ja luokittelumalli testataan vuosien 2003–2007 liiketoimintadatasta muodostetulla 389 336 kaupparivin otoksella, joka sisältää 42 186 arvioitavaa asiakkuussuhdetta. Merkittävin esille nouseva havainto on noin 5 000:n keskimääräistä selkeästi kalliimman asiakkuuden ryhmä. Aineisto ja sen poikkeavuudet testataan tilastollisin menetelmin, jotta saadaan selville asiakkuuden arvoon vaikuttavat ja arvoa selittävät tekijät. Lopuksi pohditaan arvottamismallin merkitystä analyyttisemman ostotoiminnan ja asiakkuudenhallinnan välineenä, sekä esitetään muutamia parannusehdotuksia.

Konepajan hitsaustuotannon kehittäminen kattavien laatuvaatimusten mukaiseksi

TIIVISTELMÄ Lappeenrannan teknillinen yliopisto Konetekniikan koulutusohjelma Voitto Kettunen Konepajan hitsaustuotannon kehittäminen kattavien laatuvaatimusten mukaiseksi Diplomityö 2015 167 sivua, 39 kuvaa, 26 taulukkoa ja 3 liitettä Tarkastajat: Professori Jukka Martikainen DI Pertti Kaarre Hakusanat: hitsaus, hitsauksen laatu, konepajan laadunhallinta, kattavat laatuvaatimukset, ISO 9001, ISO 3834, EN 1090 Keywords: welding, quality of welding, engineering workshop quality management, comprehensive quality requirements, ISO 9001, ISO 3834, EN 1090 Hitsaamalla liitetyt teräksiset rakenteet muodostavat ylivoimaisesti suurimman osan konepajatuotannosta. Niihin kuuluu esimerkiksi ajoneuvoja, koneita, laitteita, säiliöitä, siiloja, siltoja, mastoja, piippuja, tukirakenteita ja rakennusten runkoja. Tämän diplomityön tavoitteena on kehittää konepajan laadunhallinta sellaiseksi, että se mahdollistaa kattavien laatuvaatimusten täyttämisen hitsaustuotannossa. Laatuvaatimusten täyttämiseen pyritään käyttämällä hitsaustoimintojen standardia EN ISO 3834-2 sekä kantavien teräsrakenteiden standardeja EN 1090-1 ja EN 1090-2. Teräsrakenteiden suunnittelua ohjaa EN 1993 ja niiden toiminnallisia ominaisuuksia tuotestandardit, kuten terässavupiippu- ja säiliöstandardit. Kantavien teräsrakenteiden suunnittelua ja tuotantoa ohjaa myös seuraamusluokan CC, käyttöluokan SC ja tuotantoluokan PC kautta määräytyvä toteutusluokka EXC. Aikaisempaa enemmän tullaan panostamaan esimerkiksi asiakirjojen sähköiseen hallintaan, raaka-aineiden jäljitettävyyteen tuotteeseen, särmien ja kulmien muotoiluun, pintojen käsittelyyn, hitsien tarkastukseen, hitsaushenkilöstön pätevyyteen ja hitsaustuotannon tehokkuuteen. Saarijärven Säiliövalmiste Oy:n hitsauksen laadunhallinta sertifioitiin standardin ISO 3834-2 mukaan ja kantavien teräsrakenteiden FPC-järjestelmä standardisarjaa EN 1090 noudattaen. Samalla tehtiin päivitys laadunhallintajärjestelmään ISO 9001. Toteutus, joka tehtiin sovitussa aikataulussa, haastaa jokaisen toimijan konepajassa toiminnan, tuotannon ja tuotteiden laadun kehittämiseen uusia käytänteitä ja menetelmiä soveltaen. Kehitystoimien tuloksena toiminta on selkeämpää, ennakoitavampaa ja hallitumpaa, mikä lisää yrityksen toiminnan tuottavuutta ja kannattavuutta. Sertifioidut laatujärjestelmät ovat myötävaikuttaneet tilausten lisääntymiseen yrityksen kaikkien tuotteiden osalta.

Green aspects study in game development

Context: Game development has become increasingly important in the software industry, but this importance has not affected the way software engineering approaches and methodologies manage the differences they have with game development. Similarly, software engineering does not fully support sustainability practices, causing this element to often not be considered or even known as a requirement for a development lifecycle. Goal: The aim of this thesis is to study the mode in which games are developed, and the involved sustainable aspects and the relevant concerns regarding the migration processes. Method: A quantitative study was conducted, gathering 33 answers of game professionals from four continents, from administrative (25%) and technical oriented positions (75%). Results: Three trends were observed: 1) Agile process models are used, 2) major concerns for mobile development and digital marketing, 3) minor concerns for eco-impact elements and certain development phases such as testing and crunch time development. Conclusion: Traditional Software engineering would require a major change on its processes and models to fit with modern agile development, game development approaches and sustainable requirements.

Thyroid function in the elderly and sex hormones in elderly men: reference intervals and associations with health

Aims: The aims were to create clinically feasible reference intervals for thyroidstimulating hormone (TSH) and free thyroxine (FT4) and to analyze associations between thyroid function and self-rated health, neuropsychiatric symptoms, depression and dementia in the elderly. The second aim was also to establish reference intervals for sex hormones and to analyze associations between sex hormone levels and self-rated health, symptoms, depression and dementia in elderly men. Subjects and methods: The study population comprised 1252 subjects aged 65 years or over, living in the municipality of Lieto, south-western Finland. Self-rated health, life satisfaction, symptoms, depression, and dementia were assessed with specific questions, clinical examination and tools such as the Zung Self-report Depression Scale and the Mini-Mental State Examination. Independent variables were dichotomized, and associations of these variables with TSH, FT4 or sex hormone levels were assessed. Levels of TSH and FT4 in thyroid disease–free women and women treated with thyroxine were also compared. Results: Elevated concentrations of thyroid peroxidase antibodies (TPOAb) or thyroglobulin antibodies (TgAb) were found to have a marked effect on the upper reference limit for TSH among women, who were thyroid antibody positive more higher than suggested in several recent guidelines. After age adjustment, there were no associations between TSH levels and self-rated health, life satisfaction, or most neuropsychiatric symptoms in the thyroid disease-free population. Although women with thyroxine treatment for primary hypothyroidism had far higher TSH levels than thyroid disease-free women, there were no differences between thyroid-disease free women and women with stable thyroxine treatment regarding self-rated health, life satisfaction or symptoms. Age had a significant positive association with luteinizing hormone (LH), follicle 2 practice, one range in men aged 65 years or over can be used for T, E2 and FSH measured with the AutoDelfia method, but two separate reference intervals should be used for fT, LH and SHBG. After adjustment for age, higher levels of T and fT were associated with better self-rated health (SRH) in the reference population. After adjustment for age and body mass index (BMI), there were no associations between sex hormone concentrations and self-rated health, life satisfaction or most symptoms in concentration. Conclusion: Age-specific reference intervals were derived for thyroid function and sex hormones based on comprehensive data from a community-dwelling population with a high participation rate. The results do not support the need to decrease the upper reference limit for TSH or to lower the optimal TSH target in levothyroxine treatment in older adults, as recommended in recent guidelines. Older age or being overweight symptoms among elderly men. The associations of single symptoms with T levels were inconsistent among elderly men, although the association of low T level with diagnosed depression might be clinically significant.
