The purpose of this paper is to examine how the British press shapes the image of Lithuania. To achieve the result certain questions were raised: how often is Lithuania mentioned in the selected newspapers; what are the major topics/coverage that mention Lithuania; what is the role of Lithuania in those topics; what attitude is being formed towards Lithuania in those topics; what means are used in the image formation. Two major British newspapers The Times and The Guardian were taken for the analysis of the articles. For the research all articles between the period of the 1st January to the 31st December 2008 were used. The methods of content analysis were mostly applied though the comparison of different newspapers was also selected. The paper is divided into two main parts. The first part is used to present the general views on the media, theoretical approach, main research on national image that is formed by the media. The second part reveals the means of how and the reasons why certain sources for the reaseach were selected: the selection of the media, newspapers, articles and periods; defining the variables and formation of the code (coding schemata); gathering of information; data analysis; concluding remarks. The conclusion that was arrived is as follows. Both newspapers presented Lithuania in slightly different ways. The Times had less articles about Lithuania and the country was presented in a quite narrow context (home news) as one of the East European countries... [to full text]

The purpose of this qualitative study is to analyze the dominant propaganda strategies that were reflected in an hour-long program of Radio Martì, a broadcast produced on behalf of Voice of America in the United States and aired to Cuba. Through propaganda techniques, a content analysis was used to determine which strategies were present in the commentator's coverage of the program, El Dia de la Prensa Libre on May 3rd, 2012. This study uncovered propaganda strategies, including testimonials, flag-waving, glittering generalities, appeal to prejudice, image manipulation, over-simplicity, assertion, and third party technique, that were utilized in an effort to present nuanced perspectives on the broadcasts transmitted on Radio Martì. The use of these strategies demonstrates that the program continues to use propaganda when broadcasting to Cuba after the conflict of interest incident with the United States and Radio Martì in 2006. Beyond the analysis of this broadcast, the results of this study cannot be generalized, but they can be viewed as an exemplar of the broadcast's stance on propaganda messages to Cuba on behalf of American journalists.

This thesis investigates whether institutional journalism should receive special treatment at the hands of the law. Special treatment encompasses the affording of benefits to and the imposition of liabilities on journalistic institutions and the individuals who work for them. The arguments against special treatment are pragmatic and theoretical: pragmatic arguments emphasise, inter alia, the difficulty of providing a definition of journalism, and theoretical arguments emphasise the difficulty in explaining why special treatment can be coherent. The former can be addressed by describing how special treatment is already afforded to institutional journalism, both liabilities and benefits, to individuals and institutions, and showing that some of the problems foreseen by the pragmatic arguments have not proved as difficult as they appear. The arguments that special treatment is incoherent can be addressed by arguing that the credibility and assessability of institutional journalism still provide a prima facie rationale for special treatment irrespective of the rise of public speech on the Internet, when combined with the integral nature of journalism to democracy. Two basic arguments are advanced why this is so. The first, the free speech values argument, is a consequentialist account that holds that special treatment is appropriate when (or because) institutional journalism contributes to free speech values. It is attractive, but presents difficulties, both when considered in the abstract and when applied to the free speech value of democracy. The second, a rights-based argument, based on the notion that freedoms of speech and of the Press are distinguishable, can be based on either on Dworkin’s theory of rights as trumps or Raz’s theory of rights as interests. Raz’s account is preferable, as it complements the free speech values thesis in explaining the coherence of special treatment.

The complexity of financial analysis, particularly on selection process or decision making problems, has increased rapidly over several decades. As a result, much attention has been focused on developing and implementing the efficient mathematical models for supporting this kind of problems. Multiple criteria decision analysis, an advanced field of operations research provides analysts or decision makers a broad range of methodologies, which are all suited to the complexity of financial decision analysis. In the financial modeling, uncertainty problems are inevitable, owing to the fact that the consequences of events are not precisely known. In addition, human judgments as part of analysis also contribute to it intricacy. Correspondingly, many studies have been concentrated on integrating uncertainty theories in modeling the real financial problems. One area of interest is on the inclusion of the element of human behavior or attitudinal character of decision makers. Aggregation operator in this case can offer a wide spectrum of analysis or flexibility in modeling the human behavior in financial decision analysis. In general, the main purpose of this work is on the study of financial selection problems from the perspective of decision analysis, uncertainty theories and aggregation operators. To be specific, the decision problems under a finite or discrete case and multidimensional factors are studied. The emphasis is given on the group decision making models, notably, the Dempster-Shafer theory (DST) of belief structure, the analytic hierarchy process (AHP) and the technique for order performance by similarity to ideal solution (TOPSIS). Moreover, the uncertainty theories based on fuzzy set theory and imprecise probability are employed, together with information fusion based on the ordered weighted average (OWA) operators. Quantitative and qualitative preferences, decision strategies based on the attitudinal character of decision makers, and majority concepts for group consensus are highlighted. The specific contributions of this work are summarized as the following: • The first contribution is on developing the multi-expert multi-criteria decision making (ME-MCDM) model with respect to two-stage aggregation processes. In specific, the aggregation of criteria is based on the integration of weighted arithmetic mean (WA) and OWA. The main attention is given on the proposed alternative OWAWA operator as an extension of immediate WA and OWAWA operators. Two approaches for modeling the majority opinion of experts are studied, in which based on the induced OWA (IOWA) operators. Some modifications to the support functions are suggested as to derive the order inducing variables. The analysis of ME-MCDM model based on these aggregation processes then is conducted. In this study the selection of investment strategy is used as to exemplify the model. • The weighted-selective aggregated majority-OWA operator may be considered as the second contribution. It is as an extension of the SAM-OWA operator, where the reliability of information sources is considered. The WSAM-OWA then is generalized to the quantified WSAM-OWA by incorporating the concept of linguistic quantifier, mainly for the group fusion strategy. The QWSAM-IOWA with an ordering step is proposed for the individual fusion strategy. These aggregation operators are then implemented to the case of alternative scheme of heterogeneous group decision analysis, in particular for a selection of investment problem. • Third contribution is represented by the development of linguistic group decision making with Dempster-Shafer belief structure. Different type of linguistic aggregation operator such as the 2-tuple induced linguistic OWA operator is suggested. Specifically, it is based on order-inducing variables in which the ordering of the arguments and uncertain situations can be assessed with linguistic information. Then, by using the 2-TILOWA in the D-S framework, the belief structure-2-TILOWA operator can be formed. Some of its main properties are studied. This model is applied in a selection of financial strategies. • The extension of AHP for group decision making model is given as the fourth contribution, notably, based on the inclusion of IOWA operators. Two-stage aggregation processes used in the AHP-GDM model are extended. Firstly, a generalization of weighted maximal entropy OWA under the IOWA operator is proposed as to aggregate the criteria. Further, the majority concept based on the IOWA and Minkowski OWA-based similarity measure is suggested to determine a consensus among experts. This model provides a variant of decision strategies for analyzing the individual and the majority of experts. The application in investment selection problem is presented to test the reliability of the model. • The fifth contribution is on the integration of heavy ordered weighted geometric (HOWG) aggregation operators in AHP-GDM model. In the sense of heavy OWA operator (HOWA), the heavy weighted geometric (HWG) and HOWG are introduced as extensions of the normal weighted geometric mean (WG) and the OWG by relaxing the constraints on the associated weighting vector. These HWG and HOWG operators then are utilized in the aggregation process of AHP-GDM, specifically on the aggregation of individual judgments procedure. The main advantage of the model, besides the complete overlapping of information such in classical methods, is that it can also accommodate partial and non-overlapping information in the formulation. An investment selection problem is applied to demonstrate the model. • The extension of TOPSIS for group decision making model by the inclusion of majority concept may be considered as the sixth contribution. The majority concept is derived based on the induced generalized OWA (IGOWA) operators. Two fusion schemes in TOPSIS model are designed. First, an external fusion scheme to aggregate the experts’ judgments with respect to the concept of majority opinion on each criterion is suggested. Then, an internal fusion scheme of ideal and anti-ideal solutions that represents the majority of experts is proposed using the Minkowski OWA distance measures. The comparison of the proposed model with some other TOPSIS models with respect to distance measures is presented. Here, a general case of selection problem is presented, specifically on the human resource selection problem. • Finally, the group decision making model based on conflicting bifuzzy sets (CBFS) is proposed. Precisely, the subjective judgments of experts, mainly from positive and negative aspects are considered simultaneously in the analysis. Moreover, the weighting method for the attribute (or sub-attribute) is subject to the integration of subjective and objective weights. The synthesis of CBFS in the model is naturally done by extending the fuzzy evaluation in parallel with the intuitionistic fuzzy set. A new technique to compute the similarity measure is proposed, in which, being the degree of agreement between the experts. The model then is applied in the case study of flood control project selection problem. To sum up, the presented thesis dealt with the extension of multi-criteria decision analysis models for the financial selection problems (as a specific scope) and also the general selection problems with the inclusion of attitudinal character, majority concept and fuzzy set theory. In particular, the group decision making model, Dempster-Shafer belief structure, AHP and TOPSIS are proposed to overcome the shortcoming of the existing models, i.e., related to the financial decision analysis. The applicability and robustness of the developed models have been demonstrated and some sensitivity analyses are also provided. The main advantages of the proposed models are to provide a more general and flexible models for a wider analysis of the decision problems.
La tesis, a través del análisis y desarrollo del Análisis de decisiones, Teorías de incertidumbre y Operadores de agregación, busca contribuir al estado del arte y nuevas propuesta de las necesidades y demandas que los decisores, responsables o e inversores financieros se encuentran por la creciente complejidad de sus análisis y estrategias, sobre todo en los procesos de selección o en los problemas de decisión. Así, el objetivo principal de esta tesis es el estudio de los problemas de selección financiera desde la perspectiva del análisis de decisiones, las teorías de la incertidumbre y los operadores de agregación. En concreto, se estudian los problemas de decisión en virtud de un conjunto finito de alternativas (caso discreto) y de factores multidimensionales. En el trabajo se desarrolla una extensión de los modelos de análisis de decisiones multicriterio y multiexperto que se utilizan en la resolución de los problemas de selección financiera (como ámbito específico), pero también en los problemas de selección generales, con la inclusión del carácter actitudinal, el concepto de mayoría y la teoría de los conjuntos borrosos. En particular, el énfasis se sitúa en los modelos de toma de decisiones en grupo y en la estructura de creencias Dempster-Shafer (D-S), el proceso analítico jerárquico (AHP) i la técnica de orden de preferencia por similitud con la solución ideal (TOPSIS). Además, se aplican las teorías de incertidumbre basadas en conjuntos borrosos y de probabilidades imprecisas juntamente con la fusión de la información basada en operadores OWA. También se destaca las preferencias cuantitativas y cualitativas, las estrategias de decisión basadas en el carácter actitudinal de los decisores, y el concepto de mayoría en el consenso grupal, de forma que se propone el desarrollo de operadores OWA, la generalización de los modelos AHP y TOPSIS, juntamente con el modelo de toma de decisiones grupal y la estructura de creencias Dempster-Shafer, con el fin de superar las deficiencias de los modelos existentes en relación con el análisis de decisiones financieras. En particular, la investigación realizada se puede sintetizar en siete aportaciones específicas al state-of-the-art del Análisis de decisiones y los operadores de agregación, con aplicaciones en diferentes problemas de decisión financiera: 1. Operadores de agregación basados en los OWA en los modelos de decisión Multiexpertos y Multicriterio. 2. Operadores ponderados SAM-OWA y su aplicación en modelos GDM con operadores lingüísticos. 3. Modelos GDM con operadores lingüísticos adaptados a la teoría de Dempster-Shafer con la aplicación de operadores de agregación inducidos lingüísticos. 4. Generalización del modelo AHP para decisiones grupales usando operadores OWA inducidos. 5. Introducción de operadores OWA geométricos y pesados en los modelos GDM y AHP. 6. Ampliación de los modelos TOPSIS con operadores de agregación basados en los OWA. 7. Desarrollo y aplicación del Conflicting bifuzzy a modelos de decisión MAGDM En la tesis se demuestra la aplicabilidad y la robustez de los modelos desarrollados, tanto con un esquema de agregación de expertos clásicos como con un esquema alternativo que separa por criterios de decisión. Las principales ventajas de los modelos propuestos son que se tratan modelos más generales y flexibles para un análisis más amplio de los problemas de decisión, en particular de los de selección financiera, que incorporen diversos criterios, expertos y componentes de incertidumbre y lingüísticos.

This treatise is a study of media-related articles in the South African press February 1996 to April 1999. Through a discourse analysis approach, the treatise identifies two main discourses relating to normative press models: the watchdog discourse and the nation-building discourse. It is argued that the watchdog discourse largely resembles classical libertarian press ideals, while the nation-building discourse resembles social responsibility ideals. The analysis contains numerous examples of the tensions between the government and the newspaper industry in terms of normative press models. Finally, the treatise challenges the assumed tensions that exist between nation-building and watchdog discourses, and suggests communitarianism as an ideology which upholds the crucial interests of both the press and the government.

The Media High Council (MHC) was put in place by the 2003 constitution of the Republic of Rwanda as amended to today. As article 34 clarifies, the MHC is an independent institution which aims to address issues of media and press freedom. In the same spirit, the law number 30 /2009 of 16/9/2009 determines its mission, organisation and functioning. According to article 2 of this law, the Media High Council is responsible for protection, control and promotion of media and media professionals. Based on normative theories, qualitative methods and thematic analysis, this study has explored the policy formation of the Media High Council and how it has been balancing the seeming contradictory responsibilities of protecting and controlling media from 2007 to 2010.
