Thesis (MA)--University of Stellenbosch, 2000. / ENGLISH ABSTRACT: The study investigates text properties of the consumer-advice magazine article in Xhosa within the framework of the genre-based approach to literacy and writing. The view of writing as component of the communication competence component in Grabe and Kaplan's (1996) theory of writing is assumed. It is argued that the analysis of (non-fictional) genres is a core ability in terms of the specifications of Curriculum 2005 for outcomes-based language teaching for writing skills. The term genre as it is used within genre theory refers to a (non-fictional) text which has an identifiable social (or cultural) purpose, an identifiable form (including beginning, middle and end) and specific constrains on the possible deviations allowed in its form. This study will examine seven BONA magazine articles to establish what identifiable generic properties can be attributed to these genretexts. The cognitive move structure of these magazine articles on consumer advice will be analysed to determine whether a typical move structure occurs for this genre. The text-linguistic properties of the various magazine articles will be investigated invoking Grabe and Kaplan's model of text-structure. In particular, properties like pronominal reference conjunctive devices, which contribute to text coherence and cohesion will be considered as well as lexical choices as a reflection of communicative purpose. Finally, the study will briefly address the issue of the significance of the genre-text knowledge underlying writing skills as the relevant kind of knowledge to be developed in terms of the specifications of outcomes-based language teaching in Curriculum 2005. The kind of analytic skills exemplified in the examination of the Xhosa magazine articles are therefore necessitated for accomplishing the outcomes for writing. The nationale for developing such analytic abilities with respect to writing skills is to empower learners to be competent writers in their future career lives. / AFRIKAANSE OPSOMMING: Hierdie studie ondersoek die teks-struktuur eienskappe van die verbruikers-advies tydskrifartikel in Xhosa binne die raamwerk van die genre-gebaseerde benadering tot geletterdheid en skryfvaardigheid. Die beskouing van skryfvaardigheid as 'n komponent van die kommunikasievaardigheid komponent in Grabe en Kaplan (1996) se teorie van skryfvaardigheid word aanvaar. Daar word geargumenteer dat die analise van nie-fiksie (of nie-literêre) genres 'n kemvermoë is in terme van die spesifikasies van Kurrikulum 2005 vir uitkoms-gebaseerde taalonderrig van skryfvaardigheid. Die terme genre, soos dit gebruik word in genre-teorie verwys na 'n (nie-fiksie) teks met 'n identifiseerbare sosiale, kommunikatiewe of kulturele doelstelling, 'n identifiseerbare vorm (insluitende 'n begin, middel en einde) en spesifieke beperkings rakende die toelaatbare afwykings in vorm. Die studie sal sewe BONA tydskrifartikels ondersoek om te bepaal watter identifiseerbare eienskappe toegeskryf kan word aan hierdié genre-tekste. Die kognitiewe skuif-struktuur van hierdie tydskrifartikels oor verbruikersadvies salontleed word om te bepaal watter tipiese skuif-struktuur voorkom vir hierdie genre. Die teks-linguistiese eienskappe van die verskillende tydskrifartikels salondersoek word deur die model van Grabe en Kaplan te gebruik. In die besonder, eienskappe soos voornaamwoordelike verwysing, voegwoord-meganismes wat bydra tot tekskoherensie en kohesie salondersoek word, asook leksikale (woord) keuses as 'n refleksie van die skrywer se kommunikatiewe doelstelling. Laastens, sal die studie kortliks vraagstukke ondersoek rakende die belang van die genreteks kennis wat onderliggend is aan skryfvaardigheid as die relevante soort kennis wat ontwikkel moet word in terme van die spesifikasies van uitkoms-gebaseerde taalonderrig in Kurrikulum 2005. Die soort analitiese vaardighede wat na vore kom in die ondersoek van die Xhosa tydskrifartikels word genoodsaak ten einde die uitkomste vir skryfvaardigheid te bereik. Die motivering vir die ontwikkeling van sodanige analitiese vermoëns ten opsigte van skryfvaardigheid is om leerders te bemagtig om 'n goeie skryfvaardigheid te hê in hulle toekomstige beroepe. / ISICATSHULWA ISIXHOSA: Esi sifundo sinika sikwabonisa ngokupheleleyo ukuba nabani na obhalayo rnakacacelwe ukuba ubhalela isizwe, ngoko ke rnakabe neenjonge. Makaqiqe akucingisise oko akukhethele ukutyebisela uluntu ngako. Ibonisiwe imigaqo elandelwa ziingcali zaphesheya nezimvo zazo ngobhalo lwesicatshulwa kwaneengxaki abathe bahlangana nazo. Esi sicatshulwa sigxininise kwirnigaqo ernayi landelwe yikharikyularn equlunqwe yalungiselelwa izikolo.

Kolo xovulo kufumaniseke ukuba zintandathu kuphela i'moves' ezichongeka nezifumaneka kwezi zicatshulwa zeBona.

This study assessed the convergent validity of the Functional Assessment Informant Record for Teachers (FAIR-T; Edwards, 2002) with analog functional analyses (FAs). Participants were five teachers and students located at a specialized school serving individuals with disabilities. Teachers had worked with the student for a minimum of 1 month, and students displayed a variety of behavioral topographies. The FAIR-T was conducted by the researcher using telephone or video conferencing technology, and analog functional analyses were conducted in a clinic setting by trained therapists within the course of the student’s typical treatment plan. Results of the FAIR-T were coded according to function, and the results of the analog FAs were graphed and analyzed visually. Results of the FAIR-T and FAs indicated limited convergence between the two assessment methods, though results were somewhat inconclusive. Results are discussed in relation to the utility of the FAIR-T, particularly in the school setting. Directions for future research are discussed in light of the need to delineate efficient means with which to conduct functional behavior assessments within the schools.

Les évolutions technologiques des dernières années ont premis de mettre en évidence un nouveau domaine de recherche : les Réseaux de Capteurs Sans Fil ( RCSFs). Les RCSFs sont basés sur des systèmes embarqués à fortes contraintes de ressources telles que l'énergie, la puissance de calcul et la mémoire. Leurs domaines d'application sont vastes allant notamment de la collecte de données environnementales à la surveillance d'infrastructures en passant par l'aide aux personnes. Une application type contient de quelques dizaines à plusieurs milliers de capteurs sans fil (noeuds). Le challenge que cette thèse se propose de relever est de fournir des méthodes simples et peu intrusives pour administrer ces réseaux. L'objectif est de répondre à ce besoin en minimisant l'impact sur le fonctionnement des noeuds ainsi que le coût énergétique. La solution proposée -LiveNode Non Invasive, Context aware, and Modular management (LiveNCM)- fournit des méthodes permettant de connaître l'état des noeuds et d'interagir avec eux en prenant en compte le contexte applicatif et en utilisant des estimateurs pour minimiser les échanges. Déployé sur une application de collecte de données environnementales, LiveNCm propose un outil de supervision basé sur une extesion du protocole SNMP. Les résultats obtenus notamment sur les gains énergétiques sont importants avec une autonomie du réseau augmentée de plus de 50% pour certaines grandeurs physiques observées dans un contexte spécifique. De plus, en minimisant les échanges dans le réseau, LiveNCM limite les collisions et les goulots d'étranglement qui peuvent apparaître sur le serveur de collecte des données et entre les noeuds

Valstybė kovoje su įvairių rūšių ir formų nusikalstamumu taiko neviešo pobūdžio veiksmus, iš jų ir kriminalinės žvalgybos informacijos rinkimo būdą – nusikalstamos veikos imitavimą. Neviešo pobūdžio veiksmai būtini įgyvendinant šalių baudžiamąją politiką, bet yra neišvengiamai susiję su žmogaus teisių ir laisvių apribojimais ar kitokiais jų suvaržymais. Imituodami nusikalstamą veiką, teisėsaugos institucijų pareigūnai privalo elgtis išimtinai preciziškai, vadovautis jiems suteikta kompetencija ir neperžengti leistino elgesio ribų. Provokacija jų veikloje pripažįstama kaip absoliučiai draudžiamas veiksmas. Ji suprantama, kaip atskirų teisėsaugos institucijų pareigūnų arba su jais bendradarbiaujančių fizinių asmenų neteisėta veikla. Bet koks provokuojantis ar su provokacija supanašėjantis elgesys privalo būti vertintinas kaip neteisėtas ir peržengiantis leistinas veikimo ribas. Provokacijos esmė teismų praktikoje dažniausiai siejama su aktyvia teisėsaugos institucijų pareigūnų ar jų pasitelktų fizinių asmenų veikla. Vis dėlto, galbūt galima provokuoti ir asmens visiškai neskatinant daryti teisei priešingą veiką, nesant aktyvią provokaciją liudijančių požymių? Galbūt konstatuoti provokaciją galima ir kai dėl ilgalaikio teisėsaugos institucijų pareigūnų pasyvių veiksmų tęstinumo, turinčio esminę įtaką asmens apsisprendimui, sudaroma situacija, sukeliamomis pasekmėmis prilygstanti asmens provokavimui? Ši situacija galėtų būti laikoma pasyviąja, netiesiogine provokacija. Tai...

The aim of this thesis is to propose a model that explains the relationship between customer satisfaction, retention and loyalty based on service quality attributes. The three elements of satisfaction, retention and loyalty towards products represent ongoing challenges for the corporate financial performance. Customer behaviour analysis (known as business intelligence or customer relationship management or customer experience management) has become a major factor in the corporate decision making and strategic planning processes. Prevailing logic dictates that by improving service attributes one should expect better customer satisfaction levels. Consequently, improved satisfaction levels should increase the probability of customer retention and degree of loyalty. Substantial research work has been dedicated to explain the importance of customer behaviour measurement for industry. However, there is little evidence that there has been an overall integrating empirical research that relates the three elements of satisfaction, retention and loyalty with respect to service quality attributes. Empirical data collected from the UK mobile telecommunication for this research shows that such an objective model that is capable of capturing this three dimensional relationship will contribute towards more robust decision making and better strategic planning. The proposed thesis extracts the data about key service attributes from a combination of literature review, surveys, and interviews from the UK mobile telecommunication industry. Responses were analysed using multiple regression, regression analysis with dummy variables, logistic regression, logistic regression with dummy variables and structural equation modelling (SEM) to test variables and their interrelationships. This study makes a step forward and contributes to the body of knowledge as it: (a) highlights the role of service attribute performance towards customer satisfaction, consequently identifies attributes that affect satisfaction and dissatisfaction of customers, (b) maps the relationship between attribute importance and attribute performance, (c) optimise resource allocation process using importance-performance analysis (IPA), (d) classifies customers with respect to the role and length of relationship they have with the company (switching probability), and (e) describes the interrelationship between customer satisfaction, retention and loyalty. The novelty of the research lies in: (a) establishment of a framework that links service attribute performance to customer satisfaction and then to customer future intentions (customer retention and customer loyalty), and (b) provision of a model that could assist key decision makers in prudent usage of resources for maximum profitability. This dissertation presents a novel approach methodology and modelling construct for customer behaviour analysis. For proof of concept it presents a case study in the mobile telecommunication industry. It is worth noting that in this research work Customer Retention is interpreted as probability of switching between service providers. Customer Loyalty is interpreted as referral (word-of-mouth) activity by existing customers.

The identification of the relic particles which presumably constitute cold dark matter is a key challenge for astroparticle physics. Indirect methods for their detection using high energy astro- physical probes such as cosmic rays have been much discussed. In particular, recent ‘excesses’ in cosmic ray electron and positron fluxes, as well as in microwave sky maps, have been claimed to be due to the annihilation or decay of dark matter. In this thesis, we argue however that these signals are plagued by irreducible astrophysical backgrounds and show how plausible con- ventional physics can mimic the alleged dark matter signals. In chapter 1, we review evidence of, and possible particle candidates for, cold dark matter, as well as our current understanding of galactic cosmic rays and the state-of-the-art in indirect detection. All other chapters contain original work, mainly based on the author’s journal publications. In particular, in chapter 2, we consider the possibility that the rise in the positron fraction observed by the PAMELA satellite is due to the production through (hadronic) cosmic ray spallation and subsequent acceleration of positrons, in the same sources as the primary cosmic rays. We present a new (unpublished) analytical estimate of the range of possible fluctuations in the high energy electron flux due to the discreteness of plausible cosmic ray sources such as supernova remnants. Fitting our result for the total electron-positron flux measured by the Fermi satellite allows us to fix the only free parameter of the model and make an independent prediction for the positron fraction. Our explanation relies on a large number of supernova remnants nearby which are accelerating hadronic cosmic rays. Turning the argument around, we find encouraging prospects for the observation of neutrinos from such sources in km^3-scale detectors such as IceCube. Chapter 3 presents a test of this model by considering similar effects expected for nuclear secondary-to-primary ratios such as B/C. A rise predicted above O(100)GeV/n would be an unique confirmation of our explanation for a rising positron fraction and rule out the dark matter explanation. In chapter 4, we review the assumptions made in the extraction of the `WMAP haze' which has also been claimed to be due to electrons and positrons from dark matter annihilation in the Galactic centre region. We argue that the energy-dependence of their diffusion means that the extraction of the haze through fitting to templates of low frequency diffuse galactic radio emission is unreliable. The systematic effects introduced by this can, under specific circumstances, reproduce the residual, suggesting that the ‘haze’ may be just an artefact of the template subtraction. We present a summary and thoughts about further work in the epilogue.

In 2011, Korea ratified the Korea-US Free Trade Agreement (KORUS-FTA). This treaty remains controversial in Korean society, particularly because many Koreans claim that the indirect expropriation doctrine under investor-state arbitration in the investment chapter will allow global investors to challenge governmental regulation justified by the Korean constitution. Despite such criticism, the KORUS-FTA indirect expropriation doctrine and the Korean constitutional property doctrine share more than might be expected in practice. However, this substantive doctrinal convergence between national and global legal systems does not eliminate all risks of conflict between the nation-state and global investors; conflicts can occur whenever two actors interpret the same text differently. Once an investment dispute happens, independent investor-state arbitration reviews governmental action according to independent interpretative rules. Systems theory suggests that nation-states can turn such global challenges into opportunities by taking contextual control over global investment in relying on the global investment legal system of the global investment regime. The nation-state can convince global investors that the nation-state respects transnational investment mechanisms, whilst indirectly imbuing norm-making with minimum national interest without incurring serious damage to its reputation. To be specific, the nation-state can attract more foreign investors by accepting the indirect expropriation doctrine and the investor-state arbitration respected by global investors. Simultaneously, the nation-state can secure minimum control over global investment under legitimate regulatory power reflected in the same indirect expropriation clause. In addition, the nation-state can guide the investment tribunal to secure a balance between investment protection and the regulatory power of the host state by prescribing the proportionality principle. Contextual control can be a sub-optimal choice for the nation-state in the sense that it avoids a worst-case scenario by securing proportionality and predictability. In order to make this measure more effective, the current global investment legal system needs to secure more commensurate autonomy or autopoiesis by furthering simultaneous and balanced structural coupling with a greater variety of social powers. In this context, global constitutionalism provides national constitutional tools for the nation-state; specifically, democratic participation in national treaty-making procedures and autopoietic structuralisation of the investment arbitration mechanism can make the substantive contents and application of global investment law fairer and more acceptable, not only to global investors and strong states, but also to social movements and smaller countries. In the context of the KORUS-FTA, the Korean government needs to make the treaty terms of indirect expropriation clearer through democratic participation. At the same time, the Korea should pay attention to making arbitration process reflexive to more various social interests, whilst protecting its operation from inappropriate influences. Such measures can prevent KORUSFTA tribunals from making extremely unacceptable decisions to actors of the global investment regime, including the Korean government, although they could not guarantee ideal decisions that stratify all actors perfectly.

There is a wide range of applications for 3D printing technology with an additive manufacturing such as aerospace, automotive, marine and oil/gas, medical, consumer, electronics, building construction, and many others. There have been many pros and cons for 3D additive manufacturing. Even though 3D printing technology has many advantages: freedom to design and innovate without penalties, rapid iteration through design permutations, excellence mass customization, elimination of tolling, green manufacturing, minimal material wastes, energy efficiency, an enablement of personalized manufacturing. 3D additive manufacturing still has many disadvantages: unexpected pre- and post-processing requirement, high-end manufacturing, low speed for mass production, high thermal residual stress, and poor surface finish and dimensional accuracy, and many others. Especially, the issues for 3D additive manufacturing are on high cost for process and equipment for high-end manufacturing, low speed for mass production, high thermal residual stress, and poor surface finish and dimensional accuracy. In particular, it is relatively challenging to produce casting products with lattice or honeycomb shapes having sophisticated geometries. In spite of the scalable potential of periodic cellular metals to structural applications, the manufacturing methods of I∙AM Casting have been not actively explored nor fully understood. A few qualitative studies of I∙AM Casting has been reported. Recently, a sand casting of cellular structures was attempted, resulting in casting porosity and the sharp corners in the lattice structure of the cellular structural molds, a sharpness which prevent fluid-flow and causes undesired solidification, resulting in misrun casting defects. Research on the indirect AM methods has not been aggressively conducted due to the highly complex and multidisciplinary problems across the process – continuum modeling (thermal stress, flow, heat transfer, and water diffusion) with multiple materials (polymer, metals, and ceramic) for multiphase simulations – solid, liquid, and gas. As an initial step to fully understand the processing of I∙AM Casting, a quantitative study on I∙AM Casting is conducted in this work.

This thesis studies the impact of small states in the Common Foreign and Security Policy (CFSP) in EU. The organisation of EU contains an interdependent power relationship between all countries. The aim of this study is to examine how this interdependence affect the influence of small states. Two theoretical framework are used. The first by Robert Keohane och Joseph Nye that developed the theoretical definition of interdependence, while the second one by Søren Christensen and his definition of direct and indirect power. The analytical model contains four hypothesis concerning asymmetrical and vulnerable interdependence, as well as direct- and indirect power. Through a case study of Sweden and Finland the conclusion is that small states have influence in CFSP, but it is limited due to bigger states with much more resources and the geographical position of the countries that creats asymmetrical interdependence. However, Sweden and Finland have influence in the decision-making in CFSP through vulnerable interdependence because of their many international defence cooperations with different organizations that strengthen their national position in the international political system. Also, the formal process of decision-making in CFSP enable direct and indirect power of small states. Therefore, the final conclusion is that small states have influence in CFSP even though is its limited in some aspects.

This thesis contributes to academic debate about the question: how much substantive protection should investment treaties (IITs) provide to foreign investment? Chapters 5 and 6 argue that arbitral tribunals have interpreted fair and equitable treatment and indirect expropriation provisions of existing IITs in several different ways. Each of these interpretations is sketched as a model level of protection that could be explicitly adopted by states in the future, either through inclusion in new IITs, or through amendment to existing IITs. In this way, the thesis defines a range of prospective options available to states concerning the level of protection to provide to foreign investment through IITs. The thesis evaluates the relative desirability of these different levels of protection. The thesis argues that different levels of protection should be evaluated according to their likely consequences. The thesis develops a framework for inferring and understanding the likely consequences of adopting different levels of protection. The framework proposes that the consequences of a given level of protection can be understood in terms of its likely effect on: economic efficiency; the distribution of economic costs and benefits; flows of foreign direct investment into host states; the realisation of human rights and environmental conservation in host states; and respect for the rule of law in host states. Within this framework, the thesis provides an assessment and synthesis of existing empirical evidence and explanatory theory so far as they relate to the consequences of IIT protections. It also specifies the normative criteria by which these consequences should be evaluated. Through the application of this framework, the thesis concludes that lower levels of protection of foreign investment are, in general, likely to be more desirable than higher levels of protection.
