Framing Analysis of Kosovo Independence

Maiorescu, Roxana 11 June 2009 (has links)
On February 17, 2008 Kosovo declared its independence from Serbia and the event spurred significant media attention. Countries like Spain, Romania, and Russia feared that the event would engender separatism on their own territories, while the U.S., Germany, France, Italy, and UK regarded it as a democratic step. This thesis uses the framing theory to content analyze newspaper articles in seven languages (N=191) that appeared between November 17, 2007 and May 17, 2008, three months before and three months after Kosovo became an independent state. The thesis uses the five generic frames (responsibility, human interest, consequences, morality, and conflict) developed by Semetko and Valkenburg (2000) as well as the three 'macro-frames' (cynicism, speculation, and metacommunication) established by Constantinescu and Tedesco (2007). Results revealed that media from the countries that supported the Kosovo independence framed the event from the perspective of democracy and were almost twice more likely to discuss the position of the U.S., a key decision- maker in the Kosovo issue, than media from the countries that opposed it. Furthermore, newspaper articles from countries that did not support the event were nearly three times more inclined to present the Kosovo independence from the perspective of a precedent for separatism in Europe and the world. By applying the framing theory in an international study, this thesis sheds light on the discrepancies in media coverage from these different democratic systems. / Master of Arts

Fun With Frames: Exploring Metacommunication and Real Media Frames in South Park's Fake News

Williams, Daron 10 June 2009 (has links)
The popular cable show South Park has steadily entertained audiences since its debut in 1997. Much of the show's humor and entertainment value comes from its satirical treatment of public figures, institutions, and timely trends. One of the institutions often lampooned on the show is that of television news broadcasting. This thesis project seeks to shed light on entertainment media portrayals of television news journalists and television news journalism as a whole by examining the issues covered, how those issues are framed, and how the journalist is used as a figure on the border of entertainment and information in one show. A content analysis was performed on all news broadcasts contained within all 181 episodes of South Park through its twelfth season. Results indicate that Semetko and Valkenburg's (2000) five generic frames penetrate well into the entertainment realm; a broadcast's "relationship to reality" is framed significantly differently when Conflict and Speculation frames are employed; news broadcasters are not portrayed as exemplars of the media's "liberal bias;" and that South Park has used significantly more reality-based storylines in recent years than in its early years. / Master of Arts

Aspectos matemáticos de la descomposición de imágenes utilizando ondículas (wavelets)

Núñez Ramírez, Luis Miguel January 2010 (has links)
El propósito de la presente tesis es estudiar de manera analítica técnicas para la construcción de los elementos básicos del Análisis Multirresolución (AMR) como son los espacios Vj o la función escala y la ondícula. La idea básica de una ondícula es que ella es una función que pertenece a un cierto espacio de funciones y que sometida a dilataciones y traslaciones genera una base ortonormal, u otro tipo de base, en tal espacio. Surgen dos funciones básicas, la función escala y la función ondícula. Esta técnica de descomponer señales en términos de ondículas (o de frames), tiene gran impacto en diversas investigaciones interdisciplinarias (aplicaciones a la medicina, biología, economía, astronomía, entre otros). En este trabajo también estudiaremos, la descomposición de un espacio de funciones en subespacios, así como algunas estrategias para la construcción del polinomio trigonométrico m0; siguiendo los lineamientos matemáticos de una de las mejores exponentes de la teoría de ondículas, Ingrid Daubechies. Por otro lado, se establece la descomposición y reconstrucción de una señal sometida a un filtro, y la relación que existe entre la ondícula y el polinomio trigonométrico m0. / -- The purpose of this thesis is an analytical study of techniques for the construction of the basis elements of Multiresolution Analysis (MRA) as are the spaces Vj or scaling function ' and wavelet.

Reference Frames and Algorithms for Quantum Information Processing

Sheridan, Lana January 2009 (has links)
The main results of this thesis fall in to two areas, firstly quantum reference frames as a resource for quantum computations and secondly quantum algorithms. The results relating to quantum references consider their scaling with a requirements to perform measurements, operations and computations with a certain fidelity. For the case of a directional frame, the central question considered is of how many operations or measurements can be performed with it before its fidelity falls below some threshold. This is found to scale as the square of the size of the reference frame under for a range of physically interesting cases. To prove that result a new general form for any rotationally invariant map. This could have many applications is comparing and classifying rotationally invariant behaviour of quantum systems. Phase references are also considered for the case of performing quantum computations under an energy conservation law. The restriction that the expected energy be conserved for large quantum computations is shown to be manageable in many different potential architectures. In the case of completing computations is an energy conserving subspace, the requirements for ancillas are sublinear in the number of qubits, and even in a circuit model implementation, the errors due to phase reference imperfections are shown to not limit the apparent algorithmic improvements of quantum computing over classical computing. A quantum walk for the novel concept of two entangled walkers is proposed and analyzed. A modest improvement is found in the scaling of the expected separation of the walkers over the separable case. It illustrates the potential for making use of particle statistic behaviour in algorithms. Lastly, the relation between discrete and continuous time models of quantum computing is explored through the analysis of a new algorithm for simulating the Hamiltonian behaviour of a black box unitary operation. The scaling of the number of calls to the unitary required to obtain a simulation correct to within a parameter ϵ is found, as is a case where the efficiency of the algorithm is superior to directly applying the unitary repeatedly. Applications of the algorithm are considered.

Analytical and Experimental Study of Concentrically Braced Frames with Zipper Struts

Yang, Chuang-Sheng 20 November 2006 (has links)
This thesis investigates the performance of concentrically braced zipper frames through complementary experimental and numerical simulation approaches and proposes a design methodology for an innovative bracing scheme labeled as the suspended zipper frame. The suspended zipper frame intends to ensure that the top-story hat truss remains elastic, resulting in very ductile behavior of the structure. In the first part of the work, a three-story prototype frame was designed based on a preliminary design method. Three tests were conducted on one-third scale models of this prototype to verify the design procedure and assess the system performance under very different load histories. Comparisons of the results between analyses and experiments validated the partial-height zipper mechanism envisioned, and led to refinements of the design procedure and establishment of appropriate design details for these frames. The design and performance of this structural system are illustrated with three-, nine-, and twenty-story buildings designed for the same masses as those used in the SAC studies for the Los Angeles area. The proposed design strategy results in suspended zipper frames having more ductile behavior and higher strength than typical zipper frames. In addition, the suspended zipper frames also appear to reduce the tendency of chevron-braced frames to form soft stories and to improve seismic performance without having to use overly stiff beams. Finally, an explanation of the design philosophy as well as code language format of the design procedure is given.

The Study of Critical Successful Function to Innovate Enterprise e-Learning System - Analysis by Technology Frame

Huang, Shiow-Feng 25 January 2004 (has links)
As the coming of digital knowledge economic era, knowledge and human resources have become the most important capital of organization. Therefore, how organizations can preserve and develop knowledge is every business¡¦ concern. Because the cost of traditional training is high due to the limitation of time, space and facilities, ¡§e-Learning¡¨ can provide timely, cost-efficient, as well as high-quality lessons if there exists caring and sharing organizational culture to support organizational learning. In this study, the Technology Frame theory suggested by Orlikowski & Gash is adopted to analyze a business that implements an e -Learning system. The analysis shows that three groups, including IT staffs, HR staffs and users, exhibit positive attitude to the e-Learning system although they have different interpretations on this system. A f urther analysis shows that business strategy, culture of organization, government sponsorship, and the human resource quality influence the technology frames of IT staffs, HR staffs and users.
