Code-switching is a language-contact phenomenon in which the juxtaposition of languages is intentional and purposeful. The Kuwaiti speech community has a distinctive code-switching mechanism because of the unique sociolinguistic and cultural setting; as they code-switch to English even though they are neither an immigrant community nor are/were colonised by an English speaking country. In Kuwait, code-switching between Kuwaiti Arabic and English is very common among the youth, even though English is considered to be a foreign language. It is observed that the code-switching behaviour of Kuwaiti bilinguals attending bilingual/multilingual schools differs from that of those attending monolingual schools. In this thesis, an ethnographic study has been conducted to corroborate this observation. Both bilingual/multilingual school students and bilingual students attending monolingual schools were interviewed in order to identify the motivations behind their code-switching behaviour. The interviews were analysed sequentially by adopting the conversational analysis framework. The sequential approach (Auer 1984) focuses on a turn-by-turn participant-oriented analysis (Li Wei 1994) to seek answers to the questions of how and why bilingual speakers code-switch. Here, the different code-switching behaviours of these young Kuwaitis were investigated in an attempt to analyse the conversational functions behind them. Without exception, bilinguals in monolingual schools preferred conversing in Kuwaiti Arabic with a few one-word English insertions here and there, even though free language choice was emphasised at the beginning of each conversation. On the other hand, the language choice of bilingual school students varied from choosing Kuwaiti Arabic or English as the language of conversation to code-switching between the two languages on a continuous basis. Code-switching ranged from English insertions into Kuwaiti Arabic speech or Kuwaiti Arabic insertions into English speech to alternating between the two languages. In addition to the different code-switching styles, various conversational functions behind code-switching were also recognised. In this thesis, code-switching was treated as a contextualisation cue (Gumperz 1982), highlighting the pragmatic functions and contributing to an understanding of the intended meaning. At least five motivations behind code-switching among bilingual school students were identified in our corpus: accommodation, repair, contrastiveness, filling linguistic gaps, and floor holding, among others.

The aim of this work was to investigate the problems associated with using machine-independent intermediate codes in the translation from a high-level language into machine code, with emphasis on minimising code size and providing good run-time diagnostic capabilities. The main result was a machine-independent intermediate code, I-code, which has been used successfully to develop optimising and diagnostic compilers for the IMP77 language on a large number of different computer systems. In addition, the work has been used to lay the foundations for a project to develop an intermediate code for portable SIMULA compilers. The major conclusions of the research were that carefully designed machine-independent intermediate codes can be used to generate viable optimising and diagnostic compilers, and that the commonality introduced into different code generators processing the code for different machines simplifies the tasks of creating new compilers and maintaining old ones.

The thesis deals with different aspects of nominal collocations in Italian legislation, respectively in the Italian Civil Code (codice civile). The introductory part focuses on theory and is divided into two areas. The first area covers the most important legal and linguistic issues of the language of law and its lexical means. The description of individual legal texts according to their functional styles is drawn from an analysis of individual functions of law as a complex social phenomenon. The practical part of the thesis focuses on three groups of issues. First, all excerpts were subject to the grammatical, syntactic and conceptual analyses. The second and third chapters deal with an analysis of the main issues from the perspective of translation and lexicography respectively. Special attention is paid to the existence or absence of an identical concept in both the Italian and Czech legal systems, differences in the content and scope of related concepts and potential equivalents.

Häufig wird für kommerzielle oder wissenschaftliche Zwecke Individualsoftware benötigt. Obwohl Anwendungen häufig denselben Mustern folgen, müssen oft auch triviale Bestandteile immer wieder neu entwickelt werden, zudem erfordert die Entwicklung allgemein entsprechende Fachkenntnisse. Daher besteht die Idee Plattformen zu entwickeln, die keine oder wenig Programmierung erfordern und somit die einfache und schnelle Entwicklung von Anwendungen unterstützen, um Zeit und Kosten zu sparen. Das W3C hat für verteilte Dienste Standards für die Beschreibung von Diensten, Prozessen und auch die Präsentation etabliert. Es ist Ziel dieser Arbeit diese Standards zu kombinieren und ein kompatibles, jedoch vereinfachtes Beschreibungsformat zu entwickeln, einschließlich einem Werkzeugkasten für die Codegenerierung und Bereitstellung einer Laufzeitumgebung. Durch Modularisierung soll die Plattform einfach erweiterbar bleiben.

Previous studies have shown that teachers and students using English as the medium of instruction (EMI) in science classrooms encounter many language challenges with teaching and learning processes. Problems include the limited English communication skills of science teachers, the lack of EMI training for science teachers, the students' different language abilities and science teachers' beliefs that they are not responsible for addressing students' language needs in science. Teachers' lack of language awareness has led to poor teaching practices and limited interactions in the classrooms. This lack of language awareness, in turn, suggests that there are limited opportunities for students to learn English as a second language in the science classroom. This study extends the research on EMI classroom interactions in Hong Kong (Lo and Macaro, 2012) to the previously unexamined context of senior secondary science classrooms. A total of 19 teachers and 545 students from grades 10 and 11 EMI science class were recruited in Hong Kong from 'early-full EMI' schools (full EMI instruction from grades 7 to 12) and 'late-partial EMI' schools (Chinese medium from grades 7 to 9 and partial EMI instruction from grades 10 to 12). The project used multiple sources of qualitative data (i.e. semi-structured interviews and 33 videotaped classroom observations) to explore the similarities and differences in classroom interactions during the first and second years of the senior science curriculum (grades 10 and 11) in the two types of EMI schools. This project also investigated these science teachers' and students' perceptions of EMI teaching and learning processes, their preference of instructional language and their beliefs about teaching and learning in the EMI environment. Interviews also probed teachers' language awareness, teachers' and students' belief about EMI, students' self-concepts in science (students' perceptions or beliefs about their ability to do well in science, see Wilkins, 2004)) and their perceptions of language challenges and coping strategies in EMI classrooms. The results from the observational data show similar interactional patterns in both early-full and late-partial EMI science classrooms when measured as percentages of interaction time, distribution of time between teacher and student talk and frequency of pedagogical functions. However, the nature of the interactions is different. In late-partial EMI schools, overall, there are more (but shorter) student initiations and responses, more use of higher-order questions from the teachers but less direct feedback to students. Both teachers and students tend to use their L1 more. In both types of schools, there was less interaction time and a lower maximum length of student turns and more L1 use in grade 11 than in grade 10. The discourse analysis of the four biology lesson transcripts also shows that both early-full and late-partial EMI students predominantly produced incomplete sentences consisting of short, technical nouns or noun phrases referring to scientific items. Science teachers rarely made any attempts to correct their students' language mistakes, nor did they encourage students to produce a complete sentence. This lack of teacher feedback on students' L2 language production perhaps reflects the fact that EMI science teachers rarely provide comprehensible input to facilitate students' L2 language learning. These findings suggest the important role of the teacher's modified input in teacher-student interaction in developing students' content knowledge and language skills. The adoption of EMI appears to lead to the development of students' comprehension of content knowledge more than development of their language production skills. As a result of their language shortfalls, the students' L2 productive skills remain under-developed despite English instruction. This lack of language support by teachers appears to indicate a gap between the aims of the EMI policy and its implementation. The interview and questionnaire data show that the science teachers from both the early-full and late-partial EMI schools held many of the same views about their EMI teaching experiences, but they differed in their attitudes towards the value of English language skills and their language awareness. The early-full EMI teachers believed English language skills were important and these early-full teachers have a higher language awareness than the late-partial EMI science teachers. Students from both types of schools also held similar views about their EMI learning, indicating that they welcome the adoption of EMI instruction. However, while the late-partial EMI students see EMI as an opportunity to improve their English, those in the early-full EMI schools believe that EMI discouraged them from learning. By providing an evidence-based, pedagogically focused analysis of teacher and student classroom interactions and their perceptions, this research sheds light on ways to improve the quality of instructional practices in different EMI classrooms in Hong Kong and in similar contexts around the world.

(in English): The work in this diploma contains an analysis of speech accuracy and fluency of Russian speaking and English speaking students of Czech language, based on case studies. For these case studies two Russian speaking students and two English speaking students were chosen to take part. The results were compared to the results of one native Czech speaker. The accuracy and fluency analysis was carried out based on the language principles of Rod Ellis. Within the accuracy analysis, the number of error free clauses and the average number of mistakes per one hundred words were measured. Accuracy of speech is examined through concrete grammatical phenomena like the usage of reflexive particle se/si and the usage of the verb to be in the past tense. The work in this diploma also considers the ability of analysed speakers to switch between language codes and to distinguish features of formal and spoken Czech language (spoken language in informal situations). The fluency of speech is studied based on the speech rate of all analysed speakers by counting the number of syllables per one hundred words. Subsequently, the number of false starts, repetition of words or phrases, the frequency of usage of parasite words and hesitation sounds were also examined. One of the diploma hypothesis is the statement...

Hierdie studie fokus op die taalontwikkeling en -verryking van senior kleuters in milieubenadeelde gemeenskappe. Die ondersoekgroep is 'n A:fiikaanssprekende Kleurling- en Griekwagemeenskap.

Die implikasie vir die antwerp van 'n ouerprogram is dat die ouers nie net begelei moet word ten aansien van die taalverryking van die senior kleuters nie, maar ook eksplisiet daartoe begelei te word om potensieel-stimulerende leersituasies te skep. / This study focuses on the language development and -enrichment of senior toddlers in environmentally deprived communities. The research group is an Afrikaans speaking Colouredand Griqua community. It is evident that parents in this community reveal certain deficiencies pertaining to their language-teaching behaviour, resulting in linguistic experiential backlogs in their senior toddlers. Language development and -enrichment is in essence a socially mediated process and exposure to stimulating language experiences enhances comprehension of colloquial usage within the social context. The inadequate linguistic example set by both the family and the community results in inadequate language development and -enrichment and the senior toddlers reveal their impoverished, undifferentiated world of language in deficiencies pertaining to mastery of language, style of language and code of language. The senior toddlers' conceptualization is deficient and in their language usage they are rather descriptive and concrete-bound than analytic and abstract. It is evident that the parents do not adequately stimulate their senior toddlers' cognitive abilities, and a code of language is not adequately facilitated, because the parents do not know how to derive profit from incidental learning situations and are ignorant pertaining to the creation and utilization of potential learning opportunities. Stimulation of cognition refers to the mastery and fixation.. of certain concepts, while broadening of a code of language refers to the. ability to describe, to explain, to interpret or to communicate the meaning of these concepts. A broadened and expanded code of language is thus the result of regular exposure to a wide range of stimulating experiences. This experiential framework later becomes the toddler's referential framework which he uses to repeat information, to formulate requests, to name objects and to accurately describe events. A broadened and expanded code of language is thus essential for later successful learning, because it enables the learner to analyze, to synthesize and to globalize new information. The implication for the draft of a parental programme is that parents should not .only be accompanied pertaining to the enrichment of their senior toddlers' language development, but that parents in this deprived environment also explicitly be educated to create potential stimulating learning situations at home. / Psychology of Education / D.
