Conversation analytic approach to practiced language policies : the example of an induction classroom for newly-arrived immigrant children in France

Bonacina, Florence Marguerite January 2011 (has links)
Traditionally, language policy (LP) has been conceptualised as a notion separate from that of practice. That is, language practices have usually been studied with a view to evaluate the extent to which a LP is (or is not) implemented (e.g. Martin, 2005; Johnson, 2009). Recently, however, Spolsky (2004, 2007, 2008a) has argued that policy and practice need not be seen as distinct and that, in fact, there is policy in language practices themselves (I use the term ‘practiced language policy’). Therefore, Spolsky’s claim represents a decisive development in the field of LP research. However, this proposal remains essentially programmatic since Spolsky does not indicate how practiced language policies can be investigated. The aim of this thesis is to address this methodological gap. The main claim of the thesis is that Conversation Analysis (CA) – a method specifically developed to describe conversational practices – can be used to investigate practiced language policies. In order to support this claim, a case study has been conducted on the language practices of an induction classroom for newly-arrived immigrant children in France. In the thesis, a broad view of CA is adopted, incorporating both sequential and categorisation analysis (Membership Categorisation Analysis). More specifically, I have used the conversation analytic approach to code-switching (as developed over the last few years by researchers such as Auer, 1984; Li Wei, 2002; Gafaranga, 2009; Bonacina and Gafaranga, 2010) and investigated a corpus of audio-recorded classroom interactions I collected in the above mentioned setting. Observation of these interactions revealed a number of “norms of interaction” (Hymes, 1972) the classroom participants orient to in order to go about the routine business of talking in an orderly fashion. For example, it was observed that each of the languages available can potentially be adopted as the “medium of classroom interaction” (Bonacina and Gafaranga, 2010) depending on who is doing being the language teacher. When no one is doing being the language teacher, it was observed, a key determinant of language choice is participants’ language preference. Finally, in the absence of any shared preferred language, French was adopted. The practiced language policy of this induction classroom consists of the set of such interactional norms. It is because CA can be used to discover and describe such interactional norms that this thesis claims it can be used to investigate practiced language policies in this induction classroom and in other settings as well. In summary, this thesis is primarily a contribution to the field of LP research. It starts from recent proposals in the field, especially by Spolsky (2004, 2007, 2008a), that there is policy in practices and shows how this programmatically formulated proposal can be implemented. More specifically the thesis shows that and how CA can be used to discover a practiced language policy. The research reported here has adopted a case study methodology, investigating language choice practices in a multilingual educational setting. It therefore contributes to the study of bilingual classroom talk, albeit indirectly. This is particularly the case as there has been very few, if any, studies of bilingual classroom talk which combine both sequential and categorisation analysis.

HIGH SHOCK, COMPUTERIZED, MINIATURE, AIRBORNE PCM/FM TELEMETRY SYSTEM

Svensson, Ake, Maoz, Michael 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / Aydin Vector Division has developed and manufactured an airborne, high shock, wideband FM/FM telemetry system for Saab Missiles AB in Sweden. This system was presented in the ITC Proceedings of 1988, Volume XXIV, pp 71-84 (Ref [1]). Three such systems were supplied. Saab Missiles AB also awarded Aydin Vector Division with an additional order for a larger number of high shock, computer based, specially designed, miniature PCM/FM airborne telemetry systems. These systems were developed, manufactured and supplied to Saab Missiles AB, and have been extensively and successfully used in the Swedish program. The PCM/FM telemetry package described in this paper was used for the system testing and the firing trials program of a mortar projectile, where the measurement requirements included micro processor interfaces, as well as a high amount of analog and bi-level data channels. The paper covers the specifications of the PCM/FM system mentioned above, the concept that was used to meet these specifications, the system’s mechanical and electrical design, the packaging technique and some of the test results.

MICROMINIATURE DISTRIBUTED DATA ACQUISITION SYSTEM

PENHARLOW, DAVID 11 1900 (has links)
International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The new generation of advanced tactical aircraft and missiles places unique demands on the electronic and mechanical designs for flight test instrumentation, high bit rates, operating temperature range and system interconnect wiring requirements. This paper describes a microminiature PCM distributed data acquisition system with integral signal conditioning (MMSC) which has been used in advanced aircraft and missile flight testing. The MMSC system is constructed from microminiature, stackable modules which allow the user to reconfigure the system as the requirements change. A second system is also described which uses the same circuitry in hermetic hybrid packages on plug-in circuit boards.

Anforderungen an einen Debugger für Softwaregeneratoren

Wagner, Christina 06 May 2016 (has links) (PDF)
Eine wichtige Aufgabe bei der Softwareentwicklung ist das Auffinden von Fehlern und das Verstehen ihrer Ursachen. Zur Unterstützung dieser Aufgabe gibt es zahlreiche De-bugger. Bei der Nutzung von Softwaregeneratoren benötigt man zum Debuggen spezielle Informationen. In dieser Arbeit werden Anforderungen an einen Debugger für Software-generatoren definiert. Dazu werden zunächst strukturell ähnliche Softwaregeneratoren auf ihre Debugger untersucht und grundsätzliche Debuggertypen identifiziert. Aus diesen werden 15 Anforderungen formuliert, die der hier beispielhaft betrachtete Softwaregener-ator erfüllen soll. Anschließend erfolgen eine Verallgemeinerung der Ergebnisse und eine kurze Diskussion der Umsetzung auf der Plattform JetBrains MPS.

Combining a Reed-Solomon Block Code with a Blind Equalizer: Synchronization and Bit Error Rate Performance

Skrzypczak, Alexandre, Blanc, Grégory, Le Bournault, Tangi 10 1900 (has links)
ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NV / The performance of telemetry systems may be strongly affected by diverse sources of perturbations. Among them, multipath channels and transmission noise are the most critical. While the effects due to the multipath channels can be attenuated thanks to equalization, the effects of the noise are limited if forward error correction is used. This paper first proves that the combination of blind equalization and forward error correction can strongly improve bit error rates. The other objective of the paper is to show that reasonably powerful codes like Reed-Solomon codes are sufficient to enable quasi-error free transmissions in a large majority of propagation channel scenarios.

Revenue department versus board of investment : the challenges of the tax incentive system and FDI promotion in Thailand

Dusitnanond, Sirinya January 2011 (has links)
This thesis examines the use of tax incentives to promote foreign direct investment (FDI) in Thailand and the issues arising out of the way in which the Thai revenue system has chosen to implement these incentives. Thailand experiences sporadic political unrest, and has been affected by regional and global economic crises. Since FDI appears to increase economic growth and help the host country to achieve sustainable development, the Thai government has a clear policy to encourage FDI. Tax incentives have become a significant weapon in the Thai government’s arsenal for encouraging this aim. This thesis presents a detailed analysis of the tax incentives and the mechanisms used for their implantation. Analysis reveals that, unfortunately, the Thai government has also chosen to deliver the administration of tax incentives in to the hands of two separate bodies ─ the Revenue Department and the Board of Investment (BOI). This strategy is problematic because it creates unnecessary difficulties and uncertainty in the administration of incentives and promotes confusion among foreign investors. The jurisdictional problems inherent in the system of the dual allocation of tax incentive powers are highlighted in the landmark Minebea case, which involved conflicting interpretations by the Revenue Department and the BOI. In addressing these jurisdictional problems, this thesis examines norm conflict resolution principles in general and the lex specialis in particular, and argues that the Investment Promotion Act of 2001 (IPA 2001), being a special law, and so overrides the more general provisions of the Revenue Code. Two solutions are suggested in order to tackle the current problem: 1) to amend the IPA 2001 to specify methods of tax calculation and clearly define problematic terms and 2) to incorporate the tax incentive provisions provided for BOI-promoted companies into the Revenue Code. This is based on the premise that all tax matters, including tax incentives provisions, should be administered only by the revenue authority, i.e. the Revenue Department.
