Description
The theme for this work is the development of fast numerical algorithms for sparse optimization as well as their applications in medical imaging and source localization using sensor array processing. Due to the recently proposed theory of Compressive Sensing (CS), the $\ell_1$ minimization problem attracts more attention for its ability to exploit sparsity. Traditional interior point methods encounter difficulties in computation for solving the CS applications. In the first part of this work, a fast algorithm based on the augmented Lagrangian method for solving the large-scale TV-$\ell_1$ regularized inverse problem is proposed. Specifically, by taking advantage of the separable structure, the original problem can be approximated via the sum of a series of simple functions with closed form solutions. A preconditioner for solving the block Toeplitz with Toeplitz block (BTTB) linear system is proposed to accelerate the computation. An in-depth discussion on the rate of convergence and the optimal parameter selection criteria is given. Numerical experiments are used to test the performance and the robustness of the proposed algorithm to a wide range of parameter values. Applications of the algorithm in magnetic resonance (MR) imaging and a comparison with other existing methods are included. The second part of this work is the application of the TV-$\ell_1$ model in source localization using sensor arrays. The array output is reformulated into a sparse waveform via an over-complete basis and study the $\ell_p$-norm properties in detecting the sparsity. An algorithm is proposed for minimizing a non-convex problem. According to the results of numerical experiments, the proposed algorithm with the aid of the $\ell_p$-norm can resolve closely distributed sources with higher accuracy than other existing methods.

Description
ABSTRACT This thesis investigates the acceptability of a new variety of English among the English teaching community in Germany. A number of linguists claim there is a new variety of English developing in continental Europe, also known as Euro-English. Their research has surfaced multiple features that are unique to European speakers of English. Twenty-one teachers participated in a survey. They answered a questionnaire consisting of two parts. Part one investigates the background of the teachers, their attitudes towards different varieties of English, and their awareness of the research regarding Euro-English. Part two tests the acceptability of ten features that have been claimed to be specific for mainland Europeans. Results of this study reveal that there is little awareness of non-native varieties and many find it hard to accept the features of Euro-English. However, the teachers show a genuine interest in this topic. Where there is a general preference in holding on to the guidelines of standard norms, many comments indicate that teachers think about issues of identity and how their teaching could be affected by a broader scope that exceeds traditional methods.

Description
The primary topic of this dissertation is the grammaticalization of negation in three Sinitic language varieties: Hakka, Mandarin, and Southern Min. I discuss negative morphemes that are used under different modality or aspect contexts, including ability, volition, necessity, and perfectivity. Not only does this study examine Southern Min affirmative and negative pairs, but it also highlights the grammaticalization of negation and parametric differences in negation among the languages under investigation. This dissertation also covers the reanalysis of negatives into interrogatives. I approach the investigation of Southern Min negation from both synchronic and diachronic perspectives. I analyze corpus data in addition to data collected from fieldwork for the contemporary linguistic data. For my diachronic research of Chinese negation, I use historical texts and etymological dictionaries. Diachronically, many of the negative morphemes originate from full-fledged verbs and undergo an analogous grammaticalization process that consists of multiple stages of reanalysis from V to T (aspect; modality), and then T to C (interrogative; discourse). I explain this reanalysis, which involves head-to-head movement, using generative frameworks that combine a modified cartographic approach and the Minimalist Economy Principles. Synchronic data show that Southern Min affirmative modals are characterized by a certain morphological doubling. These doublings consist of two near synonyms used in sequence, resulting from the loss of features in a verb and a second verb added as a renewal. In the negation paradigm, some negatives project a negative phrase, while the others serve a dual function, occupying a modal/aspect head as well as a negative head. The latter system is gradually shifting to the former. This study uncovers evidence to counter the long-established paradigm, where negation is tied to its independent modality (abilitive, volitional and necessitive) or aspect (perfective and perfect). I observe a mismatch between the use of interrogatives and their modality/aspect and attribute this phenomenon to feature loss during their reanalysis from negatives to interrogatives. Results however show that consistency occurs in the grammaticalization of negation within Southern Min and intra-linguistically among the three Sinitic languages, and that parametric differences are found at the morphological level.

Description
The purpose of this study is to explore the syntax and pragmatics of subject doubling in spoken French. Many prescriptivists have considered it a redundant and ungrammatical form, but over the years, it has gained more interest from syntacticians. It is widely acknowledged that dislocations involve topics, but the position of these structures is very disputed. Some linguists believe in base generation while others state there is movement. The status of subject clitics also comes into play and their role as arguments or agreement markers is crucial to understanding the issues at stake with a topic analysis. It is often argued that the clitics are undergoing a linguistic cycle whereby they lose their function of argument, and need to be reinforced by disjunct pronouns. In this study, I examined which analyses support my data and I attempted to determine what structures tend to be most dislocated by looking at the environment of the discourse in a corpus of spoken French.

Description
The nature of imperative syntax has remained an elusive, yet ever-present, subject in syntactic research, spanning several decades of linguistic inquiry and analysis, and it is therefore unsurprising that current views on the subject continue to be somewhat divided. This thesis examines the syntactic evidence from imperatives in Old English and ultimately seeks to develop a picture of the possibilities for imperative clauses in OE alongside an overall framework for imperative syntax within contemporary theoretical models of syntactic structure. The general, perceived pattern for OE imperative clauses (e.g. Millward 1971) is “verb−first,” and statistical data from the corpora confirm this perception, with the majority of imperative clauses exhibiting the verb in clause−initial position. Imperative constructions with post− and preverbal overt subjects are also examined at length, and postverbal subjects are found to be the majority case. These results are further expanded by examinations of data from verb−second and verb−third contexts, which include possibilities for topicalized constituents and adverbs. Ultimately, the relative position of both the verb and the subject and the relationship between these and other elements in the totality of the data provide essential clues for constructing a clearer model of OE imperative syntax. Within a relatively rich cartographic framework (Rizzi 1997), I therefore argue that the imperative verb is standardly fronted to the head of ForceP, with the overt subject remaining in spec−FinP, in parallel with other models for imperative syntax and OE syntax. Exceptions to this pattern for imperatives which suggest lower positions for the imperative verb (e.g. verb−second and verb−third constructions) are also accounted for, all with the central goal of demonstrating a consistent pattern underlying the realization of imperative syntax in Old English.

Description
Spanish-speaking (SS) dual language learners (DLLs) have shown differential developmental profiles of the native language (L1). The current study examined whether or not the Spanish acquisition profile, specifically accusative clitics, in predominantly SS, Latino children continues to develop in an English-language contact situation. This study examined (1) accuracy rates of clitic production, total substitutions, and total omissions across 5-, 6-, and 7-year-olds; (2) accuracy rates of clitic production, total substitutions, and total omissions across low and high English proficiency groups; and (3) whether or not there was a trend to use the default clitic lo in inappropriate contexts. Seventy-four SS children aged 5;1 to 7;11 participated in a clitic elicitation task. Results indicated non-significant effects of age and proficiency level on the accuracy of clitic production. These results suggest dual language learners are in an environment that does not foster the maintenance of the L1, at least in the accuracy of accusative clitic pronouns.

Description
Extensive cross-linguistic data document a wide gamut of semantic and pragmatic uses of the diminutive that revolve around the fundamental concepts of `small' and `child'. As typical inventory of informal registers, diminutives are utilized as pragmatic markers of politeness in a wide range of contextual meanings. This dissertation is intended to fill some major gaps in the systematic and empirical research on the formation and pragmatic uses of the diminutives in Macedonian and to explore the role of diminutivization in a broader linguistic framework, by examining the consistency of the field of diminutives, the core and peripheral meanings of the diminutive, their typology, as well as their pragmatic potential. The morphology and pragmatics of the diminutive is examined by combining data from electronic and printed sources, video recordings of natural conversations, as well as from material collected from participant and non-participant observations. At the level of morphology, it is argued that three fundamental semantic constraints underlie the formation of diminutives: [-big], [+ emotional], and [+ informal]. Furthermore, it is shown how diminutive combinability is rule governed in Macedonian by proposing sets of formal constraints for all grades of diminutives. At the level of pragmatics, the pragmatic functions of the diminutives proper and the related periphrastic diminutive malku are investigated in a variety of contexts involving child-directed speech (CDS) and adult communication. By analyzing the pragmatic functions of the diminutive in a series of speech acts, and drawing upon cross-cultural interpretations suggested by Wierzbicka (1991), it is argued that, in Macedonian, social bonding, cordiality, intimacy or affection are pragmatically more salient than personal autonomy in the Anglo-Saxon societies, realized through non-imposition, tentativeness, or similar pragmatic strategies for saving face. Additionally, it is contended that there exist cultural differences in the assessment of the concept of imposition between these societies. The analyses of the pragmatic potential of the diminutive proper and the periphrastic diminutive 'malku' give rise to the claim that Macedonian culture is predominantly founded on the pragmatic principle of positive politeness.

Description
Past research has isolated an extension of the copular verb estar into the domain previously sanctioned for its counterpart, ser. This extension has been found in areas of contact between American English and Spanish speaking Mexican immigrants. A similar situation of contact is in occurrence in Arizona, and this study endeavored to evaluate if this same extension was present, and to what degree. This study also explores the framework of linguistic hegemony in order to relate language attitudes in Arizona to language change in Arizona. The findings revealed minimal extension. This may be due to language maintenance in response to hegemony.

Explaining Fukushima to children: a cross-cultural study of bodily functions as metaphor in Japanese
Description
This research proposes that a cross-cultural disconnect exists between Japanese and American English in the realm of bodily functions used as metaphor. Perhaps nowhere is this notion illustrated more clearly than by a cartoon that was inspired by recent tragic events in Japan. In the afternoon of Friday, March 11, 2011, the northeast coast of Japan was struck by a massive earthquake and tsunami that caused immeasurable loss of life and property and catastrophic damage to the nuclear power plant in Fukushima Prefecture. In the immediate wake of these events, Japanese artist Hachiya Kazuhiko, determined to make the situation comprehensible to children, created a cartoon in which he anthropomorphized the damaged Fukushima Daiichi reactor and likened the dangers associated with it to illness and bodily functions. This cartoon garnered considerable notoriety, both in Japan and abroad. The reactions of English speakers appeared to differ from those of Japanese speakers, suggesting the existence of a possible cross-cultural disconnect. This research into the reactions to the cartoon and other relevant literature (both in English and Japanese), viewed against federal regulations regarding the broadcast of "obscenity" in the United States, commentary on American society, and how the use of similar language in American cartoons is seen, clearly indicates that negative attitudes toward the use of bodily functions as metaphor exist in the United States, while the same usage is seen differently in Japan.

Description
ABSTRACT For this study, I chose to look at the influence that linguistics has on the publishing industry, both in writing and editing literary fiction. Both sides of publishing deal with the words and language of a novel, which is what the study of linguistics entails. Throughout this study, I researched the different areas of the publishing industry, academic programs that focus on publishing, and how-to guides on writing literary fiction in order to find out to what extent--if any--linguistics is involved. Also, through editors that I have worked with, and recommendations from various acquaintances, I interviewed two authors--one published and one unpublished--to see if they used any aspects of linguistics in their writing techniques. I found that linguistics was never specifically mentioned in the descriptions of publishing courses, in the how-to guides, nor in the answers from the authors on different writing techniques used; however, linguistics may be used or studied unintentionally.
