The field of Teaching Arabic as a Foreign Language (TAFL) has seen in recent decades a growing interest in portraying and teaching one of the most salient and intrinsic features of Arabic: language variation. This thesis takes a position in contrast to approaches that portray the two varieties as being distinct and well-defined dichotomic units, in favour of an approach that interprets them as two heterogeneous language varieties within one singular linguistic system. The two language varieties are embodied by Standard and Colloquial Arabic and it is argued here for the teaching of both varieties to students of Arabic as a foreign language. In this light, this thesis sets out to investigate the development of two language skills, vocabulary knowledge and language awareness, in a diglossic learning environment. Moreover, it explores the attitudes and perceptions of the students towards Arabic variation. Two experimental methods based on focus-on-form instruction are used in this research to teach Colloquial Arabic to students of Arabic as a foreign language at higher-education level, and the empirical research is conducted within a semi-embedded research design in which qualitative and quantitative data are collected. Students from three universities participate in this research: the Universities of Exeter, Genoa and Milan. This allows for the comparison of results from students of different mother tongues. The main research question that this thesis sets out to answer is: does focus-on-form instruction lead to vocabulary development in two diglossic varieties, namely Standard and Colloquial Arabic, more effectively when it focuses on the two varieties separately or when it links their forms? Two sub-questions investigate which of the two methods of focus-on-form instruction lead more efficiently to the development of language awareness, and the impact they have on students’ attitudes towards Arabic variation. The last sub-question asks to what extent the development of the diglossic language skills and attitudes is a consequence of the method of instruction received. The results of this study suggest that the answer lies in focusing predominantly on one variety at a time with additional consolidation exercises that compare the forms of the two varieties. The main contributions of this thesis are both theoretical, to the literature of TAFL, and empirical, regarding the development of the language skills and attitudes measured.

This thesis investigates language variation among a group of young adults in Beijing, China, with an aim to advance our understanding of social meaning in a language and a society where the topic is understudied. In this thesis, I examine the use of Beijing Mandarin among Beijingborn university students in Beijing in relation to social factors including gender, social class, career plan, and future aspiration. Language variation in this context can further our understanding of Chinese culture in a newlyreformed society while exploring important constructs such as gender and aspiration in China, in part by establishing the social meaning of the local vernacular and its role in identity construction among speakers. The study presents data from both sociolinguistic interviews, conducted with 21 Beijingers who have di erent class backgrounds, career plans, and future aspiration, and self-recordings, from a subset of 10 Beijingers in conversation with their family and/or friends. I focus on three thus far under-examined linguistic variables { neutral tone, classi er omission, and intensi er te { while incorporating an additional variable { erhua (word- nal rhotacisation) in the discussion of stylistic variation in Beijing Mandarin. The results rst provide an overview of language variation in Beijing Mandarin, as shown in the use of di erent features and their linguistic and social constraints. We observe familiar patterns often found in sociolinguistic literature for some social factors (e.g. gender), while more complex interactions exist for others (e.g. aspiration and career path). The ndings suggest that Beijing Mandarin conveys localness and masculinity which is expected for a vernacular variety. Finer distinctions in the social meanings of these variables are found in sub-groups of Beijingers with di erent gender, future career path and/or aspiration. Moreover, speakers are seen to utilise these variables and their meanings in the construction of personae.

Especially for the last twenty years, the studies of Linguistic Landscapes (LLs) have been gaining the status as an autonomous linguistic discipline. The LL of a (mostly) geographically limited area – which consists of e.g. billboards, posters, shop signs, material for election campaigns, etc. – gives deep insights into the presence or absence of languages in that particular area. Thus, LL not only allows to conclude from the presence of a language to its dominance, but also from its absence to the oppression of minorities, above all in areas where minority languages should – demographically seen – be visible. The LLs of big cities are fruitful research areas due to the mass of linguistic data. The first part of this paper deals with the theoretical and practical research that has been conducted in LL studies so far. A summary of the theory, methodologies and different approaches is given. In the second part I apply the theoretical basis to my own case study. For this, the LLs of two shopping streets in different areas of Hong Kong were examined in 2010. It seems likely that the linguistic competence of English must be rather high in Hong Kong, due to the long-lasting influence of British culture and mentality and the official status of the language. The case study's results are based on empirical data showing the objectively visible presence of English in both examined areas, as well as on two surveys. Those were conducted both openly and anonymously. The surveys are a reinsurance measuring the level of linguistic competence of English in Hong Kong. That level was defined before by an analysis of the LL. Hence, this case study is a new approach to LL analysis which does not end with the description of its material composition (as have done most studies before), but which rather includes its creators by asking in what way people's actual linguistic competence is reflected in Hong Kong's LL. / Das Forschungsfeld der Linguistic Landscape (LL) hat sich vor allem in den letzten zwanzig Jahren als autonome Disziplin im Bereich der Sprachwissenschaft emanzipiert. Die LL eines meist geografisch eingegrenzten Gebietes – die beispielsweise aus Reklametafeln, Plakaten, Ladenschildern, Wahlkampfpropaganda, etc. besteht – erlaubt tiefe Einblicke in die An- oder Abwesenheit von Sprachen auf dem jeweiligen Gebiet. Die LL lässt dadurch nicht nur Rückschlüsse auf die Dominanz einer Sprache aufgrund ihrer Anwesenheit zu, sondern auch auf die Unterdrückung einer Minderheit durch die Abwesenheit ihrer Sprache an Orten, an denen die Minderheitensprache demografisch gesehen eigentlich sichtbar sein müsste. Wegen des Überflusses an linguistischen Daten in den LLs großer Städte sind diese ergiebige Tätigkeitsfelder für die Disziplin. Diese Arbeit beschäftigt sich im ersten Teil mit der theoretischen und praktischen Forschung, die es bislang zu diesem Thema gab. Sie prüft den Stand der Theoriebildung, fasst Methodiken zusammen und gibt einen Überblick über verschiedene Ansätze. Im zweiten Teil wird die theoretische Basis auf eine eigene Fallstudie angewendet. Für diese wurden 2010 die LLs zweier Einkaufsstraßen in unterschiedlichen Gegenden Hong Kongs untersucht. Durch den dort lange währenden Einfluss der englischen Kultur und Mentalität und den offiziellen Status der Sprache liegt der Schluss nahe, dass die Sprachkompetenz des Englischen in Hong Kong eher hoch sein muss. Die Ergebnisse der Fallstudie basieren sowohl auf der Erhebung von statistischen Daten, die die objektive Anwesenheit des Englischen in der LL beider untersuchten Gegenden zeigt, als auch auf zwei daraus resultierenden Befragungen. Diese wurden zum einen offen, zum anderen anonym durchgeführt. Die Befragungen stellen eine Rückversicherung dar, die den Grad der Sprachkompetenz des Englischen in Hong Kong misst, welcher zuvor anhand der LL festgestellt wurde. Damit bietet die Fallstudie einen neuen Ansatz der Untersuchung einer LL, der im Gegensatz zu vorangegangenen Studien nicht bei der Beschreibung ihrer materiellen Beschaffenheit endet, sondern auch ihre Schöpfenden miteinbezieht und sich fragt, inwiefern die LL von Hong Kong die tatsächliche Sprachkompetenz der Menschen widerspiegelt.

This project uses corpus linguistics and geostatistics to test the sociolinguistic typological theory put forward by Peter Trudgill on the history of Norwegian. The theory includes several effects of societal factors on language change. Most discussed is the proposal that ‘intensive’ language contact causes simplification of language grammar. In the Norwegian case, the claim is that simplificatory changes which affected all of the Continental North Germanic languages (Danish, Swedish, Norwegian) but not the Insular North Germanic Languages were the result of contact with Middle Low German through the Hanseatic League. This suggests that those simplificatory changes arose in the centres of contact with the Hanseatic League: cities with Hansa trading posts and kontors. The size of the dataset required would have made it impossible for previous scholars to test this prediction, but digital approaches render the problem tractable. I have designed a 3.5m word corpus containing nearly all extant Middle Norwegian, and developed statistical methods for examining the spread of language phenomena in time and space. The project is made up of a series of case studies of changes. Three examine simplifying phonological changes: the rise of svarabhakti (epenthetic) vowels, the change of /hv/ > /kv/ and the loss of the voiceless dental fricative. A further three look at simplifying morphological changes: the loss of 1.sg. verbal agreement, the loss of lexical genitives and the loss of 1.pl. verbal agreement. In each case study a large dataset from many documents is collected and used to map the progression of the change in space and time. The social background of document signatories is also used to map the progression of the change through different social groups. A variety of different patterns emerge for the different changes examined. Some changes spread by contagious diffusion, but many spread by hierarchical diffusion, jumping first between cities before spreading to the country at large. One common theme which runs through much of the findings is that dialect contact within the North Germanic language area seems to have played a major role: many of the different simplificatory changes may first have spread into Norwegian from Swedish or Danish. Although these findings do not exactly match the simple predictions originally proposed from the sociolinguistic typological theory, they are potentially consistent with a more nuanced account in which the major centres of contact and so simplifying change were in Sweden and Denmark rather than Norway.
