本論文之目的在於探討「在」各種構式的概念、句式的意義以及語意上的各種分布，從語料中觀察母語人士和非母語人士「在」使用上的差異，並將研究結果應用於華語教材的設計中。研究者將先前關於「在」的詞類討論、構式的內容、句式義、相關變式的文獻做一整裡，發現過去「在」的研究多集中於語言現象的討論，在教學上的應用較少，於是運用認知功能學派的理論釐清「在」的概念、構式意義和功能後，調查語料庫「在」的語意和構式的分布，發現「在+處所」的構式無論是臺灣母語人士的語料庫還是中介語語料庫都顯示極高的頻率，占學習者書面語語料中的76.6％，口語語料也占了63.5％，其他語意範疇所占的比例不高，和母語人士相較下，調查結果顯示非母語人士在書面語上對「在」的使用掌握度不夠全面，仍停留在原型的語意，而口語的掌握度較高。因此，本文以構式語法和認知語言學的理論為基礎，一方面使用語料庫研究法考察語意範疇的分布，另一方面採用對比法研究檢視華語學習者的中介語句，並使用變換分析法討論句式變化的合理性，更進一步將構式、隱現、相關變式的考察成果結合認知功能教學法與任務式教學法，設計出符合認知功能主張的教材內容與練習，以幫助學生徹底掌握「在」構式的深刻內涵。 / The purpose of this study is to investigate concepts associated with zài constructions, focusing on their different meanings and semantic distributions. Having observed native speakers’ and non-native speakers’ different performances in corpora, the researcher applies the study results to the design of Taiwan Mandarin teaching materials. After reviewing literature on discussions about part of speeches of zài, zài constructions, meanings of sentences and related transformations, the researcher discovers that previous studies have made more efforts to discuss linguistic phenomena rather than pedagogic applications. As a result, by utilizing the theories of cognitive-functional approaches to clarify the concepts, constructional meanings, and functions of zài, the researcher investigates the semantic and construction distributions of zài and finds out that “zài+ location” displays the highest frequency in both corpora of native and non-native speakers: 76.6％ in interlanguage corpora in form of written language and 63.5％ in interlanguage corpora in form of spoken language. Other semantic categories, however, have lower frequency. In addition, the result of investigation indicates that non-native speakers hardly master all dimensions of zài, and they still remain at the prototypical level in written language, but know spoken language better. Therefore, based on construction grammar and cognitive linguistics, this study on the one hand uses corpus study to inspect the distribution of semantic categories, and on the other hand, adopts contrastive study to inspect Mandarin learners’ interlanguage and employs transformation analysis to debate the rationality of transformation. Furthermore, the researcher, based on the results of studies on constructions, appearance and disappearance of zài , transformations with cognition-functional teaching methods and the task-based approach, designs contents and exercises conforming to cognition-functional approaches in order to help Mandarin learners know zài constructions thoroughly.

The number of technology alternatives has lately grown to satisfy the increasingly demanding goals in modern engineering. These technology alternatives are handled in the design process as either concepts or categorical design inputs. Additionally, designers desire to bring into early design more and more accurate, but also computationally burdensome, simulation tools to obtain better performing initial designs that are more valuable in subsequent design stages. It constrains the computational budget to optimize the design space. These two factors unveil the need of a conceptual design methodology to use more efficiently sophisticated tools for engineering problems with several concept solutions and categorical design choices. Enhanced initial designs and discrete alternative selection are pursued. Advances in computational speed and the development of Bayesian adaptive sampling techniques have enabled the industry to move from the use of look-up tables and simplified models to complex physics-based tools in conceptual design. These techniques focus computational resources on promising design areas. Nevertheless, the vast majority of the work has been done on problems with continuous spaces, whereas concepts and categories are treated independently. However, observations show that engineering objectives experience similar topographical trends across many engineering alternatives. In order to address these challenges, two meta-models are developed. The first one borrows the Hamming distance and function space norms from machine learning and functional analysis, respectively. These distances allow defining categorical metrics that are used to build an unique probabilistic surrogate whose domain includes, not only continuous and integer variables, but also categorical ones. The second meta-model is based on a multi-fidelity approach that enhances a concept prediction with previous concept observations. These methodologies leverage similar trends seen from observations and make a better use of sample points increasing the quality of the output in the discrete alternative selection and initial designs for a given analysis budget. An extension of stochastic mixed-integer optimization techniques to include the categorical dimension is developed by adding appropriate generation, mutation, and crossover operators. The resulted stochastic algorithm is employed to adaptively sample mixed-integer-categorical design spaces. The proposed surrogates are compared against traditional independent methods for a set of canonical problems and a physics-based rotor-craft model on a screened design space. Next, adaptive sampling algorithms on the developed surrogates are applied to the same problems. These tests provide evidence of the merit of the proposed methodologies. Finally, a multi-objective rotor-craft design application is performed in a large domain space. This thesis provides several novel academic contributions. The first contribution is the development of new efficient surrogates for systems with categorical design choices. Secondly, an adaptive sampling algorithm is proposed for systems with mixed-integer-categorical design spaces. Finally, previously sampled concepts can be brought to construct efficient surrogates of novel concepts. With engineering judgment, design community could apply these contributions to discrete alternative selection and initial design assessment when similar topographical trends are observed across different categories and/or concepts. Also, it could be crucial to overcome the current cost of carrying a set of concepts and wider design spaces in the categorical dimension forward into preliminary design.

The aim of the study is to investigate how young men constructing identities in talk about their own use of violence. The study is based on a fieldwork at a youth detention home in Sweden. The data consists of individual interviews and video recordings of the treatment programme Aggression Replacement Training (ART). Detailed analyses have been made of conversations between the young men, between the young men and the trainers, and of the narratives generated in the individual interviews. The study has a social constructionist approach to identity, which is seen as constructed in a joint achievement in social interaction. An important analytical perspective in the study is how social categories and subcategories are constructed. The study has a particular focus on gender, primarily masculinity, but age and ethnicity are also being emphasised. The analysis draws on four empirical studies. It is shown how the young men construct a preferred self-presentation when talking about violent events. The narratives on violence are either based on experiences or talked about as a hypothetical use of violence. Violence based on personal experience is problematized and legitimized in terms of self-defence, defending friends, restraint and justified violence. Narratives of violence are shown to be interactional resources available to the young men. When talking about violence, the young men can be seen to regulate social relations, and to position themselves in relation to particular discourses of masculinity. The specific understanding of what it entails to be a man enables the use of violence with respect to social categorizations such as age, ethnicity or criminal identity. It is also argued that the treatment programme ART may, at times, facilitate maintaining a criminal identity. / Avhandlingens övergripande syfte är att undersöka hur unga män konstruerar identiteter kring berättelser om eget våldsutövande. Den bygger på en studie gjord vid ett särskilt ungdomshem i Sverige. Såväl enskilda intervjuer som videoinspelningar av behandlingsprogrammet Aggression Replacement Training (ART) har utgjort analysmaterialet. Ingående analyser har gjorts av samtalen mellan de unga männen, mellan de unga männen och behandlingspersonalen, och berättelserna i de enskilda intervjuerna. Avhandlingen bygger på en socialkonstruktionistisk ansats där identitet analyseras i social interaktion med andra. Ett viktigt analytiskt perspektiv i studien är hur sociala kategorier och underkategorier skapas. Ett särskilt fokus ligger på genus och då främst maskulinitet, men även ålder och etnicitet lyfts fram som viktiga perspektiv. Avhandlingen omfattar fyra delstudier. Studien visar hur de unga männen konstruerar en positiv självpresentation när de talar om våldshändelser. Våldsberättelserna är antingen erfarenhetsbaserade eller utgår ifrån tal om hypotetiskt våld. Det erfarenhetsbaserade våldet problematiseras och legitimeras genom att talas om som självförsvar, försvar av kompisar, återhållsamt eller rättmätigt. Studien visar att våldsberättelser är interaktionella resurser för de unga männen. Genom att tala om våld reglerar de sociala relationer och positionerar sig i relation till vissa maskulinitetsdiskurser. Den specifika förståelsen av vad det innebär att vara en man, möjliggör användandet av våld avhängigt andra sociala kategorier, så som ålder, etnicitet och kriminell identitet. Studien indikerar också att behandlingsprogrammet ART ger möjlighet att underlätta upprätthållandet av en kriminell identitet. / <p>Due to copyright matters, have the articles, published in chapter 4, 5, 6 and 7, been removed.</p>

The aim of this study is to develop a more effective translation technique analysis of the Peshitta to Ezekiel text that would contribute to the textual studies of Ezekiel. In order to help provide such an effective analysis on translation technique, the methodology employed is the comparative analysis of texts, which incorporates the theory from Cognitive Semantics called Frame Semantics. This theory views units of meaning in text or speech contexts at the level of semantic frames and is therefore most ideal in view of the idiomatic nature of the Peshitta translation. By applying this theory, the frames in the Hebrew source text of the translator were compared to those in the translator’s target Syriac text, to see whether there were correspondences between the two frames. In chapter 3, the GIVING frames evoked by נתן (nātan) were studied and it was found that most of the frames in the Hebrew text corresponded well with those in the Syriac target text. The exception is mainly those frames in which there might have been textual difficulties in the source text. Similar observations were made in chapter 4 for the ARRIVING frames evoked by the Hebrew verb בוא (bō). However, nouns associated with the frame MISDEEDS presented some problems, mainly as to their use in the Hebrew source text. The use of these nouns could have affected the translator’s understanding of such categories, leading to their inconsistent representation in the target text. Nevertheless, it can be indicated that the translator demonstrated a relatively good understanding of the use of the nouns in the Hebrew text. Overall, the translation of the Peshitta to Ezekiel was made at the approximate level of semantic frames, displaying a translation technique that should be very useful for the textual studies of the Book of Ezekiel. / PhD (Semitic Languages), North-West University, Potchefstroom Campus, 2013

Contemporary philosopher of science Nancy Cartwright (b. 1944) has raised many an eyebrow with her books How the Laws of Physics Lie (1983) and The Dappled World (1999), among others. The primary task of this dissertation is to link her philosophy with that of Charles S. Peirce (1839–1914)—a link that includes Duns Scotus. My focus is especially on the criticism Peirce would have of Cartwright, and on the philosophical support he can offer her. The question is this: Given her stated philosophy of science, to what else must Cartwright be philosophically committed? This includes discussions of metaphysics, scholastic realism, laws of nature, and the very possibility of science. There are many striking similarities between Peirce and Cartwright, but I argue that he sees further and deeper into the metaphysical implications of her views on science. / Graduate

This thesis studies how sick leave legitimacy is managed in interaction and develops an empirically driven conceptualization of ‘legitimacy work’. The thesis applies an ethnomethodological framework that draws on conversation analysis, discursive psychology, and membership categorization analysis. Naturally occurring interaction is examined in two settings: (1) multi-party meetings at the Swedish Social Insurance Agency, in which participants assess and discuss the ‘status’ of the sick leave and plan for work rehabilitation; (2) peer-based online text-in-interaction in a Swedish forum thread that gathers people on sick leave. The thesis shows how mental states, activities and alternative categories function as resources for legitimacy work. However, such invocations are no straight-forward matter, but impose additional contingencies. It is thus crucial how they are invoked. By detailed analyses of the interaction, with attention to aspects such as lexicality and delivery, the thesis identifies a range of discursive features that manage sick leave legitimacy. Deployed resources are also subtle enough to be deniable as legitimacy work, that is, they also manage the risk of an utterance being seen as invested or biased. While legitimate sick leave is a core concern for Swedish policy-making, administration, and public debate on sick leave, previous research has for the most part been explanatory in orientation, minding legitimacy rather than studying it in its own right. By providing detailed knowledge about the legitimacy work that people on long-term sick leave do as part of both institutional and mundane encounters, the thesis contributes not only new empirical knowledge, but a new kind of empirical knowledge, shedding light on how the complexities of sick leave play out in real-life situations. Traditional sociological approaches have to a significant extent treated legitimacy as an entity with beginnings and ends that in more or less direct ways relate to external norms and cognitive states, or that focus on institutions, authority or government. By contrast, the herein emerging concept ‘legitimacy work’ understands legitimacy as a locally contingent practicality – a collaborative categorially oriented accomplishment that is integral to the interactional situation.

Tourism is one of the largest industries in the world. Since the 1980s the role of tourism as a means of achieving the objectives of economic development has received prominence within the sustainable development paradigm. This dissertation examines the role of international tourism in achieving the objectives of economic development in terms of its impact on key social and economic variables, such as the balance of payments, inflation, employment and the social fabric of host communities. It also examines the constraints facing international tourism, such as the effect of perceptions on tourism flows and the powerful position of multinationals in influencing the tourist decision-making process. The success of the international tourism industry in selected countries is assessed and the relative position of the South African tourist offering is highlighted in an attempt to draw lessons for the future development of the industry in South Africa. / Economics / M.
