Tutkielman tavoitteena on tutkia, mikä olisi parhaiten case-yritykselle sopiva menetelmä tulla tekemään kauppaa ulkomaan markkinoille. Kaikki yleiset kansainvälisille markkinoilletulomenetelmät esitetään ja niiden edut ja haitat tuodaan esille. Selvittäessä tehtävänantajayrityksen resurssit, odotukset ja vaatimukset todetaan, että yhteistyössä tehtävä markkinoilletulo on pätevin vaihtoehto. Tämän jälkeen valitaan parhaiten tarkoitukseen sopiva yritys ennalta valitusta yritysvaihtoehtojen ryhmästä ja testataan tämän yrityksen yhteistyösopivuus case-yrityksen kanssa. Yritysten välinen yhteistyösopivuus arvioidaan analysoimalla yritykset haastattelujen avulla ja tutkielmassa esitettyjen teorioiden avulla. Sopivuus todetaan hyväksi, kattaen 71 prosenttia analysoiduista kohdista. Kaksikymmentäyhdeksän prosenttia kohdista todetaan kohdiksi, joissa yritysten välinen yhteisymmärrys ei ole toimeksiantajayrityksen minimivaatimukset täyttävää. Näitä kohtia tullaan käyttämään suunnittelun pohjana kun suunnitellaan jatkoneuvotteluja yhteistyön käynnistämiseksi.

Globaalinen liiketoimintaympäristö on muutoksessa. Uudet teknologiat muuttavat toimintaympäristöä ja talouden säännöt muuttuvat nopeasti. Uusia liiketoimintamalleja tarvitaan. Tutkimuksen tavoitteena oli analysoida tieto- ja viestintäteollisuuden (ICT-teollisuus) nykytilannetta strategisesta ja kilpailuanalyyttisestä näkökulmasta, sekä luoda kuva ICT-teollisuudesta ja sen suurista pelureista Euroopassa ja USA:ssa. Tutkimus analysoi viittä suurta ICT-alan yritystä. Tutkimus oli luonteeltaan sekä kvalitatiivinen että kvantitatiivinen. Yrityksiä analysoitiin käyttäen numeerista ja laadullista materiaalia. Tutkimus perustui kirjallisuuteen, artikkeleihin, tutkimusraportteihin, yritysten internet-kotisivuihin ja vuosikertomuksiin. Tutkimuksen tuloksena voitiin löytää sekä yhtäläisyyksiä että eroavaisuuksia yritysten liiketoimintamallien ja taloudellisen menestymisen väliltä.

Tutkimuksen ensisijaisena tavoitteena oli tarkastella luottamuksen rakentumista virtuaalitiimissä. Keskeistä tarkastelussa olivat luottamuksen lähteiden löytäminen, suhteen rakentuminen sekä teknologiavälitteinen kommunikaatio. Myös käytännön keinoja ja sovelluksia etsittiin. Tässä tutkimuksessa luottamus nähtiin tärkeänä yhteistyön mahdollistajana sekä keskeisenä elementtinä ihmisten välisten suhteiden rakentumisessa. Tämä tutkimus oli empiirinen ja kuvaileva tapaustutkimus. Tutkimuksessa kvalitatiivista aineistoa kerättiin pääasiassa web-pohjaisen kyselyn sekä puhelinhaastattelun avulla. Aineistonkeruu toteutettiin siis pääasiassa virtuaalisesti. Saatu aineisto analysoitiin teemoittelun avulla. Tässä työssä teemoja etsittiin tekstistä pääasiassa teoriasta johdettujen oletusten perusteella. Tutkimuksen tuloksena oli, että luottamusta rakentavia mekanismeja ovat, karkeasti luokiteltuna, yhteiset päämäärät ja vastuut, kommunikaatio, sosiaalinen kanssakäyminen ja informaation jakaminen, toisten huomioiminen ja henkilökohtaiset ominaisuudet. Mekanismit eivät suuresti eronneet luottamuksen rakentumisen mekanismeista perinteisessä kontekstissa. Virtuaalitiimityön alkuvaiheessa luottamus pohjautui käsityksille toisten tiimin jäsenten kyvykkyydestä. Myös institutionaalinen identifioituminen loi pohjaa luottamukselle alkuvaiheessa. Muuten luottamus rakentui vähän kerrassaan tehtävään liittyvän kommunikaation ja sosiaalisen kommunikaation kautta. Tekojen merkitys korostui erityisesti ajan myötä. Työssä esitettiin myös käytännön keinoja luottamuksen rakentamiseksi. Olemassa olevien teknologioiden havaittiin tukevan hyvin suhteen rakentumista tiedon jakamiseen ja sen varastoimiseen liittyvissä tehtävissä. Sen sijaan vuorovaikutuksen näkökulmasta tuen ei nähty olevan yhtä kattavaa. Kaiken kaikkiaan kuitenkin parannuksella sosiaalisissa suhteissa voitaneen saada enemmän aikaan kuin parannuksilla teknologian suhteen.

Tutkielmassa käsitellään vieraan kielen, ts. englannin, oppimista peruskoulussa. Hypoteesina oletetaan, että oppilaat, jotka jo hallitsevat kaksi kieltä, menestyvät paremmin vieraan kielen oppimisessa kuin yksikieliset oppilaat. Tutkielmassa vertaillaan kaksikielisten ja yksikielisten oppilaiden englannin kielen taitoja alakoulun kuudennen luokan päättyessä. Kaksikielisyys voidaan ymmärtää monella tavalla, ja tutkimustulokset kaksikielisyyden vaikutuksista ovat usein olleet ristiriitaisia. Siksi tutkielmassa ensin määritellään kaksikielisyys, sen lajit sekä siihen liittyvää terminologiaa. Lisäksi kuvaillaan Suomen sekä erityisesti Turun kaupungin kaksikielisen väestön tilaa ja oikeuksia sekä keskustellaan aikaisempien tutkimusten perusteella mahdollisista ongelmista ja hyödyistä, joita kaksikielisyyteen liittyy. Kaksikielisyyteen on perinteisesti liittynyt myös paljon ennakkoluuloja, kuten pelko puolikielisyydestä, jotka tieteellisten tutkimusten avulla pyritään kumoamaan. Mahdollisia muita ongelmia, kuten pienempi sanavarasto molemmissa kielissä verrattuna saman ikäisiin yksikielisiin sekä reaktioaikojen piteneminen, kuitenkin esiintyy. Kaksikielisyyden hyötyjä sen sijaan voivat olla mm. luovuus, kyky kielen analyyttiseen tarkasteluun, metalingvististen taitojen kehittyminen ja avoimuus muita kieliä ja kulttuureita kohtaan. Kaikki mainitut edut ja haitat myös vaikuttavat vieraan kielen opinnoissa menestymiseen. Myös mahdollinen positiivinen transferenssi otetaan huomioon. Tutkimuksen empiiristä osaa varten vierailtiin kahdessa turkulaisessa alakoulussa, joiden kuudennen luokan oppilaat suorittivat kaksi englannin kielen tehtävää. Toinen kouluista oli suomenkielinen, jonka oppilaat edustivat yksikielistä vertailuryhmää (n=31). Ruotsinkielinen koulu valittiin edustamaan kaksikielistä ryhmää (n=34), sillä yleensä Suomessa ja kaupungeissa kuten Turussa vähemmistökielen puhujat hallitsevat käytännössä usein myös suomen kielen. Ruotsinkielisen koulun oppilaiden kaksikielisyys varmistettiin kielitaustakyselyllä. Kaksikielisten oppilaiden tulokset molemmissa tehtävissä olivat hieman paremmat kuin yksikielisten. Yksikielisessä ryhmässä myös tulosten keskihajonta oli suurempi. Kaksikieliset näyttivät hallitsevan kielen analyyttisen tarkastelun paremmin sekä tekivät vähemmän kieliopillisia virheitä. Positiivisen transferenssin vaikutus oli myös nähtävissä. Toisaalta heillä oli enemmän oikeinkirjoitusvirheitä vastauksissaan.Merkittäviä eroja ei kuitenkaan englannin kielen oppimisessa voitu todentaa.

INTRODUCTION: The decline of malaria and scale-up of rapid diagnostic tests calls for a revision of IMCI. A new algorithm (ALMANACH) running on mobile technology was developed based on the latest evidence. The objective was to ensure that ALMANACH was safe, while keeping a low rate of antibiotic prescription. METHODS: Consecutive children aged 2-59 months with acute illness were managed using ALMANACH (2 intervention facilities), or standard practice (2 control facilities) in Tanzania. Primary outcomes were proportion of children cured at day 7 and who received antibiotics on day 0. RESULTS: 130/842 (15∙4%) in ALMANACH and 241/623 (38∙7%) in control arm were diagnosed with an infection in need for antibiotic, while 3∙8% and 9∙6% had malaria. 815/838 (97∙3%;96∙1-98.4%) were cured at D7 using ALMANACH versus 573/623 (92∙0%;89∙8-94∙1%) using standard practice (p<0∙001). Of 23 children not cured at D7 using ALMANACH, 44% had skin problems, 30% pneumonia, 26% upper respiratory infection and 13% likely viral infection at D0. Secondary hospitalization occurred for one child using ALMANACH and one who eventually died using standard practice. At D0, antibiotics were prescribed to 15∙4% (12∙9-17∙9%) using ALMANACH versus 84∙3% (81∙4-87∙1%) using standard practice (p<0∙001). 2∙3% (1∙3-3.3) versus 3∙2% (1∙8-4∙6%) received an antibiotic secondarily. CONCLUSION: Management of children using ALMANACH improve clinical outcome and reduce antibiotic prescription by 80%. This was achieved through more accurate diagnoses and hence better identification of children in need of antibiotic treatment or not. The building on mobile technology allows easy access and rapid update of the decision chart. TRIAL REGISTRATION: Pan African Clinical Trials Registry PACTR201011000262218.

The study of technology transfer in pottery production to the periphery of the Mycenaean world has been addressed by considering two different areas, southern Italy and central Macedonia. Technological features such as ceramic paste, decoration and firing have been determined for different ceramic groups established according to provenance criteria. The studies of technology and provenance have been performed following an archaeometric approach, using neutron activation analysis, petrographic analysis, X-ray diffraction and scanning electron microscopy. The results have revealed the existence of two different models. On the one hand, southern Italy seems to exhibit a more organized pottery production, which follows a Mycenaean-like technology, while in central Macedonia production is probably more varied, being based in part on the technology of the local tradition.

OBJECTIVE: It has been suggested that Schistosoma mansoni, which is endemic in African fishing communities, might increase susceptibility to human immunodeficiency virus (HIV) acquisition. If confirmed, this would be of great public health importance in these high HIV-risk communities. This study was undertaken to determine whether S. mansoni infection is a risk factor for HIV infection among the fishing communities of Lake Victoria, Uganda. We conducted a matched case-control study, nested within a prospective HIV incidence cohort, including 50 HIV seroconverters (cases) and 150 controls during 2009-2011. METHODS: S. mansoni infection prior to HIV seroconversion was determined by measuring serum circulating anodic antigen (CAA) in stored serum. HIV testing was carried out using the Determine rapid test and infection confirmed by enzyme-linked immunosorbent assays. RESULTS: About 49% of cases and 52% of controls had S. mansoni infection prior to HIV seroconversion (or at the time of a similar study visit, for controls): odds ratio, adjusting for ethnicity, religion, marital status, education, occupation, frequency of alcohol consumption in previous 3 months, number of sexual partners while drunk, duration of stay in the community, and history of schistosomiasis treatment in the past 2 years was 1.23 (95% CI 0.3-5.7) P = 0.79. S. mansoni infections were chronic (with little change in status between enrolment and HIV seroconversion), and there was no difference in median CAA concentration between cases and controls. CONCLUSIONS: These results do not support the hypothesis that S. mansoni infection promotes HIV acquisition.

En este trabajo se presenta un estudio químico y estructural de las capas metálicas de Pt y TaSix utilizadas como puerta catalítica en sensores de gas de alta temperatura basados en dispositivos MOS de SiC. Para ello se han depositado capas de diferentes espesores sobre substratos de Si. Los resultados muestran que con la reducción del espesor de Pt y con un recocido se consigue aumentar la rugosidad de las capas de puerta, lo que debería aumentar la sensibilidad y la velocidad de respuesta de los dispositivos que las incorporasen. Otro efecto del recocido es la transformación química del material de la puerta que, para capas delgadas de Pt con TaSix, produce la transformación total Pt en Pt2Ta, lo que podría afectar a las características catalíticas de la puerta. Los primeros resultados eléctricos indican que, a pesar de que las capas de Pt empleadas son gruesas y compactas, los diodos MOS túnel de SiC son sensibles a los gases CO y NO2, aunque presentan una velocidad de respuesta bastante lenta.

The main objective of this study is to assess the potential of the information technology industry in the Saint Petersburg area to become one of the new key industries in the Russian economy. To achieve this objective, the study analyzes especially the international competitiveness of the industry and the conditions for clustering. Russia is currently heavily dependent on its natural resources, which are the main source of its recent economic growth. In order to achieve good long-term economic performance, Russia needs diversification in its well-performing industries in addition to the ones operating in the field of natural resources. The Russian government has acknowledged this and started special initiatives to promote such other industries as information technology and nanotechnology. An interesting industry that is basically less than 20 years old and fast growing in Russia, is information technology. Information technology activities and markets are mainly concentrated in Russia’s two biggest cities, Moscow and Saint Petersburg, and areas around them. The information technology industry in the Saint Petersburg area, although smaller than Moscow, is especially dynamic and is gaining increasing foreign company presence. However, the industry is not yet internationally competitive as it lacks substantial and sustainable competitive advantages. The industry is also merely a potential global information technology cluster, as it lacks the competitive edge and a wide supplier and manufacturing base and other related parts of the whole information technology value system. Alone, the industry will not become a key industry in Russia, but it will, on the other hand, have an important supporting role for the development of other industries. The information technology market in the Saint Petersburg area is already large and if more tightly integrated to Moscow, they will together form a huge and still growing market sufficient for most companies operating in Russia currently and in the future. Therefore, the potential of information technology inside Russia is immense.

The subject of the thesis was the digital audio broadcasting technology developed in the Eureka project 147. The research was based on the literature on the subject. At first, some reasons for the digitisation of broadcasting technology were given. Next, the channel multiplexing and channel coding methods employed by digital radio were discussed. The design of these methods is based on certain phenomena related to the propagation of radio-frequency signals, and these phenomena were also described. After that, audio and data transfer mechanisms as well as the structure of digital radio network were explained. Furthermore, digital audio and data services were considered. Finally, the digital radio was examined from marketing and administrative aspects. From a merely technical point of view, the digital radio technology offers several improvements in comparison with analogue technology. However, the digital radio has not become as widespread as it was perhaps originally expected during its development.

The purpose of the research was to investigate operational processes related to home care of the elderly as well as use of assistive devices in smart home environments, and operational processes that are generally related to use of assistive devices – from the point of view of productivity improvement. The themes were looked into from the points of view of both the elderly and care personnel. In addition, perspectives of near relatives of the elderly, of the larger service system as well as of companies that provided assistive devices to the smart homes were taken into consideration. In the study of home care processes, 32 customer interviews and 17 employee interviews were carried out. This report contains a summary that is based on a separate report of the home care study. The study of home care was conducted in 2006. The use of technological and mechanical assistive devices and the related operational processes were investigated with the help of the smart home pilot in 2007–2008. The study is described in this report. The smart home pilot was implemented in four different housing service units for elderly people at Lahti, Nastola and Hollola. They were in use during short-term housing periods related to, for instance, end of hospitalisation, holidays of caring relatives and assessment of living and housing conditions. More than 60 different assistive devices and technologies were brought to the smart homes. During the pilot period, experiences of customers and personnel as well as processes related to the use of assistive devices were investigated. The research material consisted of 20 survey questionnaires of personnel and customers, four interviews with customers, five interviews with personnel, feedback survey responses from 14 companies, and other data that were collected, for instance, in orientation events. The research results highlighted the need for tailored services based on an elderly person’s needs and wishes, while taking advantage of innovative and technological solutions. As in the earlier home care study, also assistive device-related operational processes were looked into with the help of concepts of ‘resource focus’, ‘lost motion’ and ‘intermediate landing’. The following were identified as central operational processes in assistive device-related services (regardless of the service provider): (1) acquisition process of technologies and assistive devices as well as of rearrangement and rebuilding works in the home, (2) introduction and orientation process (of the elderly, their relatives and care personnel), (3) information and communication process, and (4) service and monitoring process. In addition, the research focused on design and desirability of assistive devices as well as their costs, such as opportunity costs. The process-based points of view gave new knowledge that may be used in the future to develop service processes and clarify their ownership so that separately managed cross-functional processes could be built with participants from different sectors to operate alongside organisations of elderly care. Development of functionality of assistive device-related services is a societally significant issue.

The purpose of this study was to increase the understanding of the role and nature of trust in asymmetric technology partnership formation. In the knowledge-based "learning race" knowledge is considered as a primary source for competitive advantage. In the emerging ICT sector the high pace of technological change, the convergence of technologies and industries as well as the increasing complexity and uncertainty have forced even the largest players to seek cooperation for complementary knowledge and capabilities. Small technology firms need the complementary resources and legitimacy of the large firms to grow and compete in the global market place. Most of the earlier research indicates, however, that partnerships with asymmetric size, managerial resources and cultures have failed. A basic assumption supported by earlier research was that trust is a critical factor in asymmetric technology partnership formation. Asymmetric technology partnership formation is a dynamic and multi-dimensional process, and consequently a holistic research approach was selected. Research issue was approached from different levels: the individual decision-maker, the firm and the relationship between the parties. Also the impact of the dynamic environment and technology content was analyzed. A multitheoretical approach and a qualitative research method with in-depth interviews in five large ICT companies and eight small ICT companies enabled a holistic and rich view of the research issue. Study contributes on the scarce understanding on the nature and evolution of trust in asymmetric technology partnership formation. It sheds also light on the specific nature of asymmetric technology partnerships. The partnerships were found to be tentative and the diverse strategic intent of small and large technology firms appeared as a major challenge. The role of the boundary spanner was highlighted as a possibility to match the incompatible organizational cultures. A shared vision was found to be a pre-condition for individual-based fast trust leading to intuitive decision-making and experimentation. The relationships were tentative and they were continuously re-evaluated through the key actors' sense making of the technology content, asymmetry and the dynamic environment. A multi-dimensional conceptualization for trust was created and propositions on the role and nature of trust for further research are given.

UNLABELLED: In vivo transcriptional analyses of microbial pathogens are often hampered by low proportions of pathogen biomass in host organs, hindering the coverage of full pathogen transcriptome. We aimed to address the transcriptome profiles of Candida albicans, the most prevalent fungal pathogen in systemically infected immunocompromised patients, during systemic infection in different hosts. We developed a strategy for high-resolution quantitative analysis of the C. albicans transcriptome directly from early and late stages of systemic infection in two different host models, mouse and the insect Galleria mellonella. Our results show that transcriptome sequencing (RNA-seq) libraries were enriched for fungal transcripts up to 1,600-fold using biotinylated bait probes to capture C. albicans sequences. This enrichment biased the read counts of only ~3% of the genes, which can be identified and removed based on a priori criteria. This allowed an unprecedented resolution of C. albicans transcriptome in vivo, with detection of over 86% of its genes. The transcriptional response of the fungus was surprisingly similar during infection of the two hosts and at the two time points, although some host- and time point-specific genes could be identified. Genes that were highly induced during infection were involved, for instance, in stress response, adhesion, iron acquisition, and biofilm formation. Of the in vivo-regulated genes, 10% are still of unknown function, and their future study will be of great interest. The fungal RNA enrichment procedure used here will help a better characterization of the C. albicans response in infected hosts and may be applied to other microbial pathogens. IMPORTANCE: Understanding the mechanisms utilized by pathogens to infect and cause disease in their hosts is crucial for rational drug development. Transcriptomic studies may help investigations of these mechanisms by determining which genes are expressed specifically during infection. This task has been difficult so far, since the proportion of microbial biomass in infected tissues is often extremely low, thus limiting the depth of sequencing and comprehensive transcriptome analysis. Here, we adapted a technology to capture and enrich C. albicans RNA, which was next used for deep RNA sequencing directly from infected tissues from two different host organisms. The high-resolution transcriptome revealed a large number of genes that were so far unknown to participate in infection, which will likely constitute a focus of study in the future. More importantly, this method may be adapted to perform transcript profiling of any other microbes during host infection or colonization.
