Taalpolitiek en "Alternatiewe Afrikaans"

Pieterse, H. J., 1960- 11 1900 (has links)
Text in Afrikaans / Die term "Alternatiewe Afrikaans" is die afgelope dekade telkens gebruik in taalpolitieke publikasies, maar tot dusver is daar relatief min gedoen om die begrip te analiseer, om die "Alternatiewe Afrikaanse beweging" histories te kontekstualiseer, en om die "beweging" se taalpolitieke uitgangspunte en publ ikasies krities te evalueer as ideologiese teenpool vir Standaardafrikaans of "Establishment Afrikaans". Hierdie proefskrif poog om, na aanleiding van 'n analise van die politieke faktore rondom die opkoms en "kanoni sering" van Standaardafri kaans, die totstandkoming van (wit) Afrikanerhegemonie en die daarmee gepaardgaande breuk in die Afrikaanse taalgemeenskap, die ontstaan van die term "Alternatiewe Afrikaans" en die taalpolitieke "agenda" van die "Alternatiewe beweging" te ondersoek. In die eerste hoofstuk word die taalsosiologie en taalpolitiek as studieterreine ontleed en terme soos "politiek", "mag" en "ideologie" en die verskei e wyses waarop hull e met taa 1 in verband gebri ng kan word, word ondersoek. Die "Kritiese Linguistiek" word onder die loep geneem en die hegemoniemodel van Gramsci word bespreek as deelteoretiese raamwerk vir hierdie studie. In die tweede hoofstuk word die taalpolitiek van Standaardafrikaans bespreek aan die hand van die volgende temas: Afrikanernasionalisme en Afrikaans, die politisering en mitologisering van die ontstaansgeskiedenis van Afrikaans, en die Afrikaanse taalbewegings. Tel kens word "alternatiewe", ontmitologiserende beskouings teenoor "standaardbeskouings" van die temas gestel. Die ontsluiting van 'n alternatiewe hegemonie, verbind met die "Alternatiewe beweging" en "People's Education", word in hoofstuk 3 bespreek en die term "Alternatiewe Afrikaans" word ontleed. Daar word besin oor die "Alternatiewe beweging" as "taalbeweging". In die vierde hoofstuk word die ideologie van "bevryding" in 'n aantal tekste wat met "Alternatiewe Afrikaans" geassosieer word, geanaliseer aan die hand van verskeie tegnieke uit die kritiese diskoersanalise. Manipulatiewe en propagandistiese diskursiewe praktyke word uitgelig. Die "depolitisering" en "demokratisering" van Afrikaans word in die slothoofstuk bespreek. Daar word aangetoon dat "Alternatiewe Afrikaans" deur 'n duidelike polities-mobiliserende agenda onderle word, dat die varieteit 'n verpolitiseerde "ideologiese metalek" van Afrikaans is en uiteindelik 'n etiket is vir " 'n ideologie van bevryding" ten opsigte van die heersende hegemoniese strukture / During the past decade the term "Alternative Afrikaans" has frequently been used in publications on language politics. Until recently little has been done concerning the analysis of this term and the contextualisation of the "Alternative Afrikaans movement". The politico-linguistic premises and publications of the "Alternative movement", as an ideological opposition to Standard Afrikaans or "Establishment Afrikaans", have not yet been sufficiently and critically evaluated. The aim of this thesis is to investigate the origin of the term "Alternative Afrikaans" and the politico-linguistic "agenda" of the "Alternative movement", with analogical reference to the political factors surrounding the rise and "canonisation" of Standard Afrikaans, the establishment of (white) Afrikaner hegemony and the concomitant division within the Afrikaans language community. In the first chapter the sociology of language and language politics are discussed, and terms such as "politics", "power" and "ideology" and the various ways in which they may be connected with language, are examined. The field of "Critical Linguistics" and Gramsci's hegemonic model are discussed as partial theoretical frameworks for this study. In the second chapter the language politics of Standard Afrikaans is discussed on the basis of the following themes: Afrikaner Nationalism and Afrikaans, the politicisation and mythologising of the ontogenesis of Afrikaans, and the Afrikaans language movements. "Alternative", demythologising views, contrary to the "standard" views on these themes, are discussed. The develpment of an alternative hegemony, linked with the "Alternative movement" and "People's Education", is considered in chapter three and the term "Alternative Afrikaans" is analysed. The "Alternative movement" is analysed as "language movement". In chapter four the ideology of "liberation" in a number of texts associated with "Alternative Afrikaans" is analysed on the basis of various techniques used in critical discourse analysis. Manipulative and propagandistic discursive practices are highlighted. The "depoliticisation" and "democratisation" of Afrikaans are considered in the final chapter. It is argued that "Alternative Afrikaans" is based on a specific agenda of political mobilisation, that this variety is a politicised "ideological metalect" of Afrikaans and ultimately a "label" for an "ideology of liberation" with regard to the prevailing hegemonical structures / Afrikaans & Theory of Literature / D.

RANGE SAFETY CASE STUDY: WESTERN RANGE CENTRALIZED TELEMETRY PROCESSING SYSTEM (WR CTPS), A LARGE DISTRIBUTED GROUND SYSTEM

Mather, Jonathan, Shaw, Nancy 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper presents a case study of the Western Range Centralized Telemetry Processing Subsystem (WR CTPS). This system was developed by Lockheed Martin Integrated Systems and Global Services and L-3 Communications Telemetry-West as part of the Range Standardization and Automation (RSA) IIA program. Requirements included real-time simultaneous acquisition of 16 PCM streams at rates of up to 30M bits per second; real-time processing; and data display on workstations connected over a gigabit Ethernet network. This system is designed for range safety and needs to be fault-tolerant while maintaining 100 percent data availability in the event of a single failure during an operation. The development of such a system demanded a rigorous Systems Engineering approach to ensure the successful upgrade and deployment onto the range infrastructure. This case study provides an overview of the system technical requirements and its architecture. The summary presents challenges encountered during the development and lessons learned while meeting them.

On the origin and measurement of noise emission in pneumatics

Waerder, Maximilian, Murrenhoff, Hubertus 03 May 2016 (has links) (PDF)
Noise is a circumstance of ordinary life and mainly originated by continually growing dynamic and the rapid development of society. In the industrial environment there are noise-intensive parts that influence the condition of present operators negatively. Thus, measures of noise abatement have been investigated intensely by industrial companies as well as federal agencies. As a subdomain of fluid power pneumatics is especially known for characteristic noise emission by the use of air as power transmission. The transient decompression of air from pressure levels up to 8 bar and partly high flow rates nearby sonic speed cause the emergence of direct airborne noise at vent ports of pneumatic components. The following paper outlines the mechanisms that induce the emission of high sound pressure levels. In order to achieve reproducible results a test bench for varying pneumatic standard components is introduced. Based on a selection of those components results are compared to standardized measurement procedures whether fulfilling the standardizations’ requirements. In conclusion, two benefits are achieved. Firstly, standardization is derived enabling neutral comparison of standard pneumatic components’ noise emission. Secondly, the measures can be evaluated to determine the most promising way to redesign pneumatic components of lower noise emissions.

The standard translation dictionary as an instrument in the standardization of Fang

Afane Otsaga, Thierry 04 1900 (has links)
Dissertation (PhD)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: This dissertation offers metalexicographical criteria for the compilation of standard translation dictionaries in non-standardized languages. It particularly focuses on the role that the proposed dictionary model can play in the language standardization, with special reference to Fang. These criteria are based on different theoretical frameworks. Criteria for the dictionary structure are particularly based on Hausmann & Wiegand's General Theory of Lexicography, while a discussion of the role that dictionaries can play in the standardization process of languages is particularly based on criteria introduced by Zgusta. This dissertation is structured as follows: • Chapter 1, Introduction and problem statement, presents the motivation for the choice of the present topic, as well as the theoretical frameworks that I use to build my metalexicographical criteria. • Chapter 2, Fang and its dialects, focuses on the concerned language and its dialects. Apart from a historical overview of the Fang people, a wide inventory of works that have been implemented in Fang, as well as the choice and the motivation of the standard dialect are presented. • Chapter 3, Dictionaries and corpora, highlights the strong relationship between the compilation of modern dictionaries and electronic corpora. More precisely this chapter intends to demonstrate the importance of electronic corpora in the lexicographic practice. In this regard, the importance of some software and new corpus methods are also demonstrated. • Chapter 4, Aspects of the dictionary structure, mainly focuses on different structures of the dictionary and how data should be spread and organized in each dictionary component. A detailed account is given of the structure of each dictionary component. • Chapter 5, Dictionaries and standardization, focuses on the main purpose of the dissertation and demonstrates why and how the dictionary can be an instrument in the standardization process of languages, with specific reference to Fang. • Chapter 6, Concluding remarks, reviews all chapters by highlighting the focal points of each of them. Some perspectives or potential new developments are foreseen in order to pave the way for the elaboration of new theoretical frameworks and the improvement of the proposed dictionary model. / AFRIKAANSE OPSOMMING: Hierdie proefskrif bied metaleksikografiese kriteria vir die samestelling van standaard vertalende woordeboeke vir nie-gestandaardiseerde tale. Die fokus is veralop die rol wat die voorgestelde woordeboekmodel kan speel in taalstandaardisering, met spesifieke verwysing van Fang. Hierdie kriteria is gebaseer op verskillende teoretiese raamwerke. Kriteria vir die woordeboekstruktuur is veral gebaseer op Hausmann en Wiegand se algemene leksikografieteorie, terwyl 'n bespreking van die rol van woordeboeke in die standaardiseringsproses van tale veral gebaseer is op kriteria wat deur Zgusta voorgestel is. Die proefskrif is soos volg saamgestel: • Hoofstuk 1 bied 'n motivering vir die keuse van die betrokke onderwerp asook vir die teoretiese raamwerke waarvolgens die metaleksikografiese kriteria geformuleer is. • Hoofstuk 2 fokus op die betrokke taal, Fang, en sy dialekte. Naas 'n historiese oorsig van die Fang sprekers word 'n wye keuse uit die Fang literatuur asook die keuse van 'n standaarddialek aan die orde gestel. • Hoofstuk 3 wys op die sterk verhouding tussen die samestelling van 'n moderne woordeboek en elektroniese korpora. Hierdie hoofstuk benadruk die belang van elektroniese korpora vir die leksikografiese praktyk. In hierdie verband word daar ook verwys na die belang van sekere sagtewareprodukte asook nuwe korpusmetodes. • Hoofstuk 4 is veral gerig op die verskillende woordeboekstrukture en op hoe data versprei en in die verskillende woordeboekkomponente aangebied moet word. Die struktuur van elke woordeboekkomponent word in besonderhede bespreek. • Hoofstuk 5 fokus op die hoofdoel van die proefskrif en wys hoe en waarom In woordeboek, met spesifieke verwysing na die situasie van Fang, In instrument kan wees in die taa Istandaardiseri ngsproses. • Hoofstuk 6 gee In oorsig oor die voorafgaande hoofstukke en wys op sekere belangrike aspekte wat bespreek is. Nuwe ontwikkelinge wat voorsien word om die weg te baan vir die ontwerp van nuwe teoretiese raamwerke ter verbetering van die voorgestelde model word beklemtoon.

Using a Simulation Model to Compare Methods of Tree-Ring Detrending and to Investigate the Detectability of Low-Frequency Signals

Bunn, Andrew G., Sharac, Timothy J., Graumlich, Lisa J. January 2004 (has links)
We use a simulation model to generate tree-ring like data with systematic growth forcings and subject it to two methods of standardization: Regional Curve Standardization (RCS) and Negative Exponential Curve Standardization (NECS). The coherency between very low frequency forcings (hundreds of years) and the chronologies was higher when RCS was used to detrend the component series. There was no difference between standardization methods at decadal or annual time scales. We found that the detectability of systematic forcings was heavily dependent on amplitude and wavelength of the input signal as well as the number of trees simulated. These results imply that for very long tree-ring chronologies where the analyst is interested in low-frequency variability, RCS is a better method for detrending series if the requirements for that method can be met. However, in the majority of situations NECS is an acceptable detrending method. Most critically, we found that multi-centennial signals can be recovered using both methods.

Building markets: The political economy of technology standards

Murphree, Michael Bruce 22 May 2014 (has links)
This dissertation explains the causes of national differences in markets for technology. Different national approaches to intellectual property protection and use, market openness and market scope are the result of the process of creating technology standards in different countries. Technology Standards, in turn, are the product of two causal variables: the historically determined institutions of standardization - particularly the role of the state in the standardization process, and the position of a country in the fragmented global production system. The institutions of standardization determine the relative influence of different actors over standardization and market position. The position within the global economy determines these actors’ perspectives on intellectual property and market scope. Using case studies of standardization and technology market creation in the United States, Europe and China, this dissertation reveals the mechanisms by which these two variables give rise to national differences in technology markets.

Standardising written feedback on L2 student writing / Henk Louw

Louw, Henk January 2006 (has links)
The primary aim of this study is to determine whether it is possible to standardize written feedback on L2 student writing for use in a computerised marking environment. It forms part of a bigger project aimed at enhancing the feedback process as a whole The study attempts to establish "best practice" with regards to feedback on writing, by establishing from the literature what works and what should be avoided. Also, an empirical study was launched to establish what lecturers focus on and what marking techniques they use. A set of randomly selected essays from the Tswana Learner English Corpus and the Afrikaans Learner English Corpus were sent to the English departments of different tertiary institutions across the country. The essays were marked by the English lecturers at the relevant institutions. The conclusion was that lecturers typically focus on surface structures, and use ineffective marking techniques. The best practice (and data from the empirical study) was then used to create a set of standardised feedback comments (tag set) that can be used in a specially programmed software package in which students submit their texts electronically. Lecturers can then mark the student essays on the computer, hopefully speeding up the process, while at the same time giving much more detailed feedback. In later stages of the bigger project, students will get individualized exercises based on the feedback, and there are experiments currently being run to try and automate certain pans of the marking process in order to take some strain off the lecturers when marking. The immense archiving abilities of the computer will also be utilized in order to create opportunities for longitudinal studies. The effectiveness of the feedback tag set was tested in comparison to the marking techniques used by the lecturers in the empirical study and a self-correcting exercise. The conclusion was that the feedback tag set is more effective than the other two techniques. but students seem to perform weak overall when it gets to the revision of cohesive devices and supporting arguments. I argue that students are not used to revising these features, since lecturers seldom (if ever) comment on the structural elements of texts. However, the experiment proves that standardization of written feedback is possible to an extent. The implications of the findings are discussed, and recommendations for further research are made. / Thesis (M.A. (English))--North-West University, Potchefstroom Campus, 2006

The impact of ERP deployment upon organizational structure : a mixed method study of Chinese practices

Wang, Leitao January 2007 (has links)
Information technology (IT) plays an important role in the daily operation of the modem business organization. The implications for, and influences on organizational structure from the deployment of IT have long been recognized. One of the most important, recent innovations, in the world of information technology, has been the Enterprise Resource Planning (ERP) system. Because of its wide reach, sophistication and highly integrated nature, it is potentially far more powerful and advanced than any of its predecessors, and thus has the potential to greatly influence organizational practices and design. However, the understanding of the organizational impact of IT in general, and ERP in particular, is rather limited. Due to the shortcomings of past studies, no clear consensus has been reached with respects to the structural impact of IT Moreover, though there 4ave been a large number of studies focusing on the implementation of EPR, very few empirical works have explicitly and systematically explored the influence of ERP on a range of different structural dimensions. This study aims to fill these gaps in the literature, and in so doing, generate a more comprehensive understanding of the organizational impacts of ERP To this end, it adopted a mixed method in order to deliver a more balanced and richer set of conclusions. The outcomes of the quantitative data analysis confirmed the general influences of ERP on a range of different structural dimensions. More specifically, it has been shown that the deployment of ERP can lead to a flatter, more decentralized, more standardized and a more tightly integrated organizational structure. Furthermore, the qualitative data provided meaningful insight into the structural impact of ERP, in Chinese context. In addition,, the various analyses found important associations amongst the corporate strategy, organizational structure, ERP deployment and organizational flexibility constructs, and in so doing, demonstrated that the relationship between ERP deployment and organizational structure is not independent of its organizational context. Indeed, it is shown that the results of this study provide support for the 'configurational' view of organizational strategy and behaviour. Finally, this study's results have been strengthened by modelling the technological artefact using a more balanced set of measures than had been employed in previous studies. Indeed, it was demonstrated that the use of ERP success, rather than the scale of its adoption, to model the independent variable, was a more effective indicator of changes to structural design, and ultimately also to the realization of organizational flexibility.
