No full textEU Integration of Turkey: Implications for Turkish Agriculture
No full textTurkey’s membership to the EU will involve full liberalization of agricultural trade with the EU. The effects of liberalization are bound to depend on the path of agricultural policies in Turkey and in the EU during the accession negotiations. In order to evaluate the possible impacts of a variety of policy alternatives and scenarios, an economic modelling approach based on non-linear mathematical programming is appropriate. In this framework, the major purpose of this paper is to evaluate the impact of Turkish integration to the EU on agriculture using an agricultural sector model for Turkey. The basic approach undertaken supplements the past efforts by incorporating Maximum Entropy to the positive mathematical programming, together with updated base period and including recent policy changes. Following the integration with EU, the net exports in agro-food products decline mainly due to the expansion of trade in livestock products. Overall welfare effects of including agrofood products in the customs union and membership are small. Consumers benefit from declining prices. CAP supports are determinative for producers’ welfare. The results of the simulations provide also updated estimates about the possible size of CAP expenditures for Turkish agriculture.Turkish Agricultural Sector Model (TAGRIS), Maximum Entropy Based Positive Mathematical Programming, Turkey’s Membership of EU, International Relations/Trade,
Re-inscribing the author : an approach to the pragmatics of reading and interpretation in Sol Plaatje's Native Life in South Africa and Luke's Book of Acts
No full textSubmitted to the Faculty of Arts in fufilment of the requirements for the Degree of Doctor of Philosophy in the Department of English at the University of Zululand, 1999.The objective of this study is to affirm the presence of the intentional consciousness / stance in texts which purport to depict reality or real events. Intentionality, in the context of this thesis, is not conceived as a pre-existing thought or idea, which precedes the text, but as something, which inheres in the text and is produced in it. The Cartesian split between consciousness and being which the former conception enacts is here elided and authorial intention is read and produced in the process of writing itself.
This distinction is significant because the main argument of this thesis is that authorial intention in texts that purport to depict real events and intervene in a particular socio-historical process for mobilizational purposes, leads to the production of a certain kind of text which deploys specific narrative strategies that consolidate its reading and rendering of events and re-inforce narrative closures. These intentionally motivated closures are embedded in narrative strategies, which are seen as both necessary and imperative for the consolidation and legitimation of the message and to foreclose other readings. Authorially motivated closures are predominant in classic realist texts in which as Roger Webster (1990:70) argues "there is a clear hierarchy of discourses controlled by a privileged central voice or narrator". This narrative voice or, to quote MacCabe, this "authorial and authoritarian 'metalanguage' judges and controls all other discourses in the text". And in classic realist texts in which the author does not seek to mask his presence by using other narrators and overtly seeks to move his audience in a specified direction, these closures become even more evident within the texture of the text. Texts of this nature are seen as means of achieving particular ends rather than as autonomous, independent units existing in a self-referential world of significance.
Much of contemporary critical theory has unfortunately tried to efface the author from the text and/ or tried to marginalize the role of the author in the text. This thesis, however, seeks to re-inscribe the agency of the author in his / her intentional stance with regard to the text, more specifically in texts which depict real events and seek to impact upon the real world and the target audience. This thesis shows how this agency is enacted within the world of the text. Very briefly, this agency, I argue, is reproduced in narrative strategies which revolve around the twin poles of authority and legitimation; and these strategies operate at two levels within the text and these are the levels of the real events depicted in the narrative and then the prevailing discursive paradigms of the times. A narrative dialectic is thus erected between these two levels in the texts and this is mediated at every point by the active presence of the authorial engagement.
The first chapter, which is largely introductory, serves as the theoretical clearing ground for the thesis. In it, I argue the case for intentionality by reviewing various critical positions in contemporary theory in relation to the author and the interpretation of texts. Thereafter I move on to spell out the ways in which authorial intention is embedded in realist narratives of the kind I have described. In my argument, I draw upon the critical practices and theoretical positions of postcolonial, feminist and Third World writers and critics whose work constitute an alternative tradition in which is inscribed specifically overt socio-political agencies. In the chapters that follow, I adopt the strategy of sketching out the historical and discursive context of the text. Thus chapter two focuses on the historical and discursive context of Luke's Book of Acts while chapter three focuses on the analysis of Acts. In the same manner, chapter four focuses on the historical and discursive context of Sol Plaatje's Native Life in South Africa while chapter five focuses on the analysis of the text (Native Life in South Africa). A brief conclusion sums up the argument of the thesis.University of Zululan
Modeling and assessing the effects of the sea surface, from being flat to being rough and dynamic
No full textThe sea surface acts as a very strong reflector because of the large impedance contrast between water and air. The reflection coefficient is -1 in a very good approximation. Apart from the surface multiples, the sea surface is also responsible for generating the source and receiver ghost wavefields. These cause the well-known ghost notches in the spectrum: areas where the signal-to-noise ratio is very low. To model the ghost wavefields, ghost operators can be computed and applied to ghost-free data. Modeling experiments indicate that in the case of a flat sea surface, the character of the notches in various gather types, e.g., receiver gather, common-offset gather, shot record, is largely determined by the complexity of the earth. In a simple earth, e.g., horizontally layered, the notches are always well-defined and deep, but in a complex earth, they become blurry in some of the gather types. Therefore, in the case of a complex subsurface, source deghosting is best carried out in the common-receiver domain and receiver deghosting is best carried out in the common-shot domain. In the case of a simple subsurface, deghosting can be carried out in all domains. An additional factor is that the sea surface may be rough and dynamic. This causes blurry ghost notches in all gather types, even in the case of a simple earth. To model the source ghost for this situation, an effective static rough sea surface suffices. This keeps the computations simple. The condition is that the source has an impulsive character. However, to model the receiver ghost (and the source ghost for a nonimpulsive source), the dynamics of the sea surface must be included. This can be done by composing the final result from the results computed for several "frozen" snapshots of the dynamic sea surface.Accepted Author ManuscriptApplied Geophysics and Petrophysic
