JAVA APIS FOR BLUETOOTH WIRELESS TECHNOLOGY

Bluetooth™ Teknologia - Bluetooth Wireless Technology - on lyhyen kantaman langaton kommunikointiteknologia. Vaikka se onkin ensisijaisesti suunniteltu kaapelin korvaajaksi laitteiden omaan toimintaan liittyvässä liikenteessä, voidaan sitä myös käyttää alustana monen käyttäjien peleissä ja muissa vastaavissa sovelluksissa. Tassa diplomityössä esitellään Bluetooth teknologia sovellusohjelmoijan näkökulmasta. Työssä esitellään teollisuuskonsortion määrittelemä Java-ohjelmointirajapinta Bluetooth teknologiaan. Tämän rajapinnan avulla voidaan kehittää kannettavia sovelluksia jotka kommunikoivat Bluetooth yhteyden yli. Rajapinta pohjautuu "Java™ 2 Microedition" alustaan ja on siten toteutettavissa myös pienissä laitteissa kuten matkapuhelimissa. Työssä esitellään lyhyesti rajapinnan keskeiset osat sekä annetaan esimerkki rajapinnan käytöstä. Työn konstruktiivisessa osassa rajapinnan keskeiset on toteutettu kahdelle eri alustalle: Sambian™ ja Microsoft® Windows® käyttöjärjestelmille. Talla tavalla on saatu arvokasta tietoa siitä, miten kyseinen rajapinta tulisi toteuttaa ja myös siitä miten sovellukset sitä käyttäisivät. Keskeiset suunnitteluratkaisut ja saadut kokemukset on raportoitu työn kirjallisessa osassa. Vaikka työn konstruktiivinen osuus onkin luonteeltaan esitutkimus eikä tähdännyt tuotteeseen, on tuloksena syntynyttä rajapintaa tarkoitus käyttää useassa Nokian sisäisessä tutkimus-ja kehityshankkeessa.

GATA2 is required for lymphatic vessel valve development and maintenance.

Heterozygous germline mutations in the zinc finger transcription factor GATA2 have recently been shown to underlie a range of clinical phenotypes, including Emberger syndrome, a disorder characterized by lymphedema and predisposition to myelodysplastic syndrome/acute myeloid leukemia (MDS/AML). Despite well-defined roles in hematopoiesis, the functions of GATA2 in the lymphatic vasculature and the mechanisms by which GATA2 mutations result in lymphedema have not been characterized. Here, we have provided a molecular explanation for lymphedema predisposition in a subset of patients with germline GATA2 mutations. Specifically, we demonstrated that Emberger-associated GATA2 missense mutations result in complete loss of GATA2 function, with respect to the capacity to regulate the transcription of genes that are important for lymphatic vessel valve development. We identified a putative enhancer element upstream of the key lymphatic transcriptional regulator PROX1 that is bound by GATA2, and the transcription factors FOXC2 and NFATC1. Emberger GATA2 missense mutants had a profoundly reduced capacity to bind this element. Conditional Gata2 deletion in mice revealed that GATA2 is required for both development and maintenance of lymphovenous and lymphatic vessel valves. Together, our data unveil essential roles for GATA2 in the lymphatic vasculature and explain why a select catalogue of human GATA2 mutations results in lymphedema.

Language Ability and Motivation among Foreigners in Survey Responding

With increasing migration and linguistic diversification in many countries, survey researchers and methodologists should consider whether data provided by individuals with variable levels of command of the survey language are of the same quality. This paper examines the question of whether answers from resident foreign respondents who do not master available survey languages may suffer from problems of comprehension of survey items, especially items that are more complicated in terms of content and/or form. In addition, it addresses the extent to which motivation may affect the response quality of resident foreigners. We analyzed data from two large-scale surveys conducted in Switzerland, a country with three national languages and a burgeoning foreign population, employing a set of dependent measures of response quality, including don't know responses, extreme responding, mid-5 responding, recency effects, and straight-lining. Results show overall poorer response quality among foreigners, and indicate that both reduced language mastery and motivation among foreigners are relevant factors. This is especially true for foreign groups from countries that do not share a common language with those spoken in Switzerland. A general conclusion is that the more distant respondents are culturally and linguistically from the majority mainstream within a country, the more their data may be negatively affected. We found that more complex types of questions do generally lead to poorer response quality, but to a much lesser extent than respondent characteristics, such as nationality, command of the survey language, level of education, and age.

Contrast : a concept in language and its development in Medieval Spanish

The purpose of this PhD thesis is to investigate a semantic relation present in the connection of sentences (more specifically: propositional units). This relation, which we refer to as contrast, includes the traditional categories of adversatives - predominantly represented by the connector but in English and pero in Modern Spanish - and concessives, prototypically verbalised through although / aunque. The aim is to describe, analyse and - as far as possible - to explain the emergence and evolution of different syntactic schemes marking contrast during the first three centuries of Spanish (also referred to as Castilian) as a literary language, i.e., from the 13th to the 15th century. The starting point of this question is a commonplace in syntax, whereby the semantic and syntactic complexity of clause linkage correlates with the degree of textual elaboration. In historical linguistics, i.e., applied to the phylogeny of a language, it is commonly referred to as the parataxis hypothesis A crucial part of the thesis is dedicated by the definition of contrast as a semantic relation. Although the label contrast has been used in this sense, mainly in functional grammar and text linguistics, mainstream grammaticography and linguistics remain attached to the traditional categories adversatives and concessives. In opposition to this traditional view, we present our own model of contrast, based on a pragma-semantic description proposed for the analysis of adversatives by Oswald Ducrot and subsequently adopted by Ekkehard König for the analysis of concessives. We refine and further develop this model in order for it to accommodate all, not just the prototypical instances of contrast in Spanish, arguing that the relationship between adversatives and concessives is a marked opposition, i.e., that the higher degree of semantic and syntactic integration of concessives restricts some possible readings that the adversatives may have, but that this difference is almost systematically neutralised by contextual factors, thus justifying the assumption of contrast as a comprehensive onomasiological category. This theoretical focus is completed by a state-of-the-question overview attempting to account for all relevant forms in which contrast is expressed in Medieval Spanish, with the aid of lexicographic and grammaticographical sources, and an empirical study investigating the expression of corpus in a corpus study on the textual functions of contrast in nine Medieval Spanish texts: Cantar de Mio Cid, Libro de Alexandre, Milagros de Nuestra Sehora, Estoria de Espana, Primera Partida, Lapidario, Libro de buen amor, Conde Lucanor, and Corbacho. This corpus is analysed using quantitative and qualitative tools, and the study is accompanied by a series of methodological remarks on how to investigate a pragma-semantic category in historical linguistics. The corpus study shows that the parataxis hypothesis fails to prove from a statistical viewpoint, although a qualitative analysis shows that the use of subordination does increase over time in some particular contexts.

Translations and Translators of English-language Literature in Catalan Literary Publications and Series between 1868 and 1910

Translations into Catalan of English and American authors during the final quarter of the nineteenth century are few and far between. Numerically, English-language literature most likely ranks fifth or sixth among all the translations of this period. We take inventory here of translations found in Catalan magazines from this time (the oldest dates from 1868) and in published series that came out at this time (if these continued until later, we trace them up to their final year). At the same time, the translators are examined, including reference, where available, as to whether the translations are direct or indirect. Finally, we consider some possible causes for the low English-language volume in Catalan translation during the period.

More than Words? An Analysis on the Language and Structure of General Election Manifestos of the British Labour Party 1983-2005

The topic of this study is the language of the educational policies of the British Labour party in the General Election manifestos between the years 1983-2005. The twenty-year period studied has been a period of significant changes in world politics, and in British politics, especially for the Labour party. The emergence educational policy as a vote-winner of the manifestos of the nineties has been noteworthy. The aim of the thesis is two-fold: to look at the structure of the political manifesto as an example of genre writing and to analyze the content utilizing the approach of critical discourse analysis. Furthermore, the aim of this study is not to pinpoint policy positions but to look at what is the image that the Labour Party creates of itself through these manifestos. The analysis of the content is done by a method of close-reading. Based on the findings, the methodology for the analysis of the content was created. This study utilized methodological triangulation which means that the material is analyzed from several methodological aspects. The aspects used in this study are ones of lexical features (collocation, coordination, euphemisms, metaphors and naming), grammatical features (thematic roles, tense, aspect, voice and modal auxiliaries) and rhetoric (Burke, Toulmin and Perelman). From the analysis of the content a generic description is built. By looking at the lexical, grammatical and rhetorical features a clear change in language of the Labour Party can be detected. This change is foreshadowed already in the 1992 manifesto but culminates in the 1997 manifesto which would lead Labour to a landslide victory in the General Election. During this twenty-year period Labour has moved away from the old commitments and into the new sphere of “something for everybody”. The pervasiveness of promotional language and market inspired vocabulary into the sphere of manifesto writing is clear. The use of the metaphors seemed to be the tool for the creation of the image of the party represented through the manifestos. A limited generic description can be constructed from the findings based on the content and structure of the manifestos: especially more generic findings such as the use of the exclusive we, the lack of certain anatomical parts of argument structure, the use of the future tense and the present progressive aspect can shed light to the description of the genre of manifesto writing. While this study is only the beginning, it proves that the combination of looking at the lexical, grammatical and rhetorical features in the study of manifestos is a promising one.

Maintenance process development for remote administration of network servers

Maintenance is a part of system development and it is possible to develop operation models for accomplishing maintenance tasks. These models can be applied to individual maintenance tasks, maintenance projects and version management. Beneficial operation models makes maintenance more effective and they assist in managing various changes. The purpose of this thesis was to develop a maintenance process which can be used to remote administer network servers. This consisted of defining those operation models and technical specifications which enable to set up, manage changes, maintain and monitor resources of information systems that are located in several different sites. At first in this thesis the needs of the process were determined and requirements were defined based on those needs. The meaning of processes in maintenance of information systems, maintenance workflows and challenges were studied. Then current practical problems and disadvantages of maintenance work were analyzed in order to focus the development to proper issues. Because available operation models did not cover all the recent needs, new maintenance process which fulfilled the requirements was developed.

Language Flexibility: The Effects of Finnish-Swedish Bilingualism on EFL Acquisition

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.

Maintenance and development of supplier relationships in an environment of irregular demand

The main target of the study was to find ideas for maintenance and development of supplier relations in irregular business environment. The other aim was to find out the suppliers’ opinions concerning the case company and the relationship between the companies. The study was conducted by using both qualitative and quantitative research methods. A mail survey was used to find out supplier opinions and an interview to find out suppliers’ ideas for relationship maintenance and development. It was found out that the use of relational elements is essential in the relationship maintenance in an irregular environment. In development of supplier relations the company should make better use of its suppliers’ potential, assure better flow of information and utilize the possibilities of Supplier Relationship Management.
