Mente firme e coração blindado: uma teoria da presentificação social na prática comunicacional de representar o crime no proibido / Strong mind and armored heart: a theory of social presentification in the communicational practice of representing crime in funk \"proibido\" music.

Fernandez, Luciana Moretti 09 June 2017 (has links)
Esta tese trata da prática comunicacional de representar o crime no funk proibido, uma prática complexa que implica processos disposicionais e identitários e que está inscrita em territórios submetidos à influência das regras que regem o mundo do crime, operando no plano intersubjetivo como um jogo de linguagem adaptativo e no plano social como uma prática coletiva. Representar implica reiterar a vontade para ratificar o compromisso com o crime ou para mostrar consideração e conviver com seus efeitos. A ratificação da disposição para representar, para ganhar potência e funcionar como uma estratégia de sobrevivência, precisa estar sempre atualizada. Reiterando-se ao longo do tempo, cada manifestação da disposição para representar o crime recupera o momento anterior e a expectativa de futuro, atualizando o gesto no momento presente. A disposição para representar o crime opera como uma presentificação no plano social, que contribui para a manutenção da subjetivação no crime e ao mesmo tempo entranha a potência de transformação através da constituição de um sujeito político cujo lugar de enunciação é o mundo do crime. A tese foi construída a partir da análise de letras de música de funk proibido artesanal que circulam no YouTube (totalizando 303 minutos de áudio), adotando como metodologia a Análise Situacional, uma refundamentação da Teoria Fundamentada nos Dados (Grounded Theory). As letras foram submetidas à codificação aberta no programa NVivo Pro 11, o que possibilitou a formulação da categoria central representar o crime. A categoria central foi analisada com as ferramentas cartográficas propostas pela metodologia Análise Situacional, conduzindo à formulação de uma teoria da presentificação social sobre a construção da subjetividade na prática comunicativa. O método de inferência adotado foi o método abdutivo, e a coleta e a análise foram guiadas por amostragem teórica. O funk proibido foi teorizado como um dispositivo interacional estético a partir do qual é possível observar o fenômeno comunicacional como processo tentativo e probabilístico em uma concepção pragmatista das teorias da comunicação. / This thesis object is the communicational practice of representing crime in funk \"proibido\" music, a complex practice that involves dispositional and identitary processes inscribed in territories under the influence of the world of crime rules, and that operates on the intersubjective level as an adaptive language game and on the social level as a collective practice. Representing implies reiterating the will to ratify the commitment to crime or to show consideration to it and coexist with its effects. In order to gain power and function as a survival strategy, the ratification of the disposition has to be always up to date. Over time, each manifestation of the disposition to represent crime recalls the previous moment and the expectation of future, updating the gesture in the present moment. The disposition to represent crime operates as a presentification on the social level, which contributes to the maintenance of subjectivation in crime and at the same time carries the power of transformation through the constitution of a political subject whose voice emanates from the world of crime. The thesis was constructed from the analysis of lyrics of funk \"proibido\" music pieces that circulate on YouTube (totaling 303 minutes of audio), following Situational Analysis (a re-foundation of Grounded Theory) as methodology. The lyrics were submitted to open coding using NVivo Pro 11 software, which led to the formulation of representing crime as the central category. The central category was analyzed using Situational Analysis cartographic tools, leading to the formulation of a theory of social presentification on the construction of subjectivity in communicational practice. The inference method followed was abduction, and the collection and analysis were guided by theoretical sampling. The funk \"proibido\" music itself was theorized as an aesthetic interactional device in which it is possible to observe the communicational phenomenon as a tentative and probabilistic process, understood under a pragmatist tradition in the field of communication theory.

The Solidarity Economy has been widely presented and discussed, both in academia and in the institutional environment, as a possible alternative to unemployment and job insecurity, and have the cooperative movement as an important tool in this process. The cooperative garbage collectors, like other members, working for the same ideals and united by the same goals, directing its activities to meet their personal and financial needs, and the appreciation of the work. In this sense, the objective of this study is to discuss the role of labor unions in promoting solidarity economy, from a case study conducted by the Badameiros Cooperative of Feira de Santana (COOBAFS), identifying that economic and social benefits this organization provided to their members. An analytical survey was conducted, conducted in the form of a case study with a qualitative approach. The results showed that the initiative despite facing problems related to the absence of external supporters and local government, has managed to maintain its continuity over time, fairly ensuring the survival of its members which, in most cases, receive monthly up to one minimum wage They are women and have not finished elementary level. It is concluded that the initiative has contributed to enable the withdrawal of its public economic marginalization and precarious spaces and working conditions, but still need to take significant steps to ensure that these better quality of living conditions and health, which It could be solved if there were in the local community, effective support from public authorities, in promoting solidarity economy, through projects that congregassem support to recyclers, which reveal a niche market to be explored in the city, reserved for political neglect / O crescimento do desemprego, juntamente com as modificações no mercado de trabalho e na própria organização econômica no Brasil e no mundo, está desencadeando um forte processo de expansão de novas formas de organização do trabalho e da produção. A Economia Solidária vem sendo amplamente apresentada e discutida, tanto no meio acadêmico como no ambiente institucional, como uma possível alternativa ao desemprego e à precariedade do trabalho, e tem o cooperativismo como um importante instrumento neste processo. Os catadores de lixo cooperativados, assim como outros cooperados, trabalham em prol dos mesmos ideais e unidos pelos mesmos objetivos, direcionando suas atividades para a satisfação das suas necessidades financeiras e pessoais, e da valorização do trabalho. Nesse sentido, o objetivo desse estudo é discutir o papel das cooperativas de trabalho na promoção da Economia Solidária, a partir de um estudo de caso realizado junto à Cooperativa de Badameiros de Feira de Santana (COOBAFS), identificando que benefícios econômicos e sociais esta organização proporcionou a seus associados. Foi realizada uma pesquisa analítica, conduzida sob a forma de um estudo de caso, com abordagem qualitativa. Os resultados demonstraram que a iniciativa apesar de enfrentar problemas relacionados à ausência de apoiadores externos e do governo local, vem conseguindo manter sua continuidade ao longo dos tempos, garantindo razoavelmente a sobrevida de seus cooperados que, em sua maioria, recebem mensalmente até um salário mínimo, são mulheres e possuem o nível fundamental incompleto. Conclui-se que a iniciativa tem contribuído para possibilitar a retirada de seu público da marginalização econômica e do precarização de espaços e condições de trabalho, mas ainda precisa avançar de modo significativo para garantir a esses melhores condições de qualidade de vida e saúde, o que poderia ser resolvido, se houvesse na comunidade local, apoio efetivo das entidades públicas, na promoção da economia solidária, por meio de projetos que congregassem o apoio aos recicladores, que revelam um nicho de mercado a ser explorado no município, reservado ao descaso político

Crazy priest versus terrorist people : Den mediala framställningen av muslimer kring utspelet med pastor Terry Jones plan att bränna Koranen

Eléhn, Christophe, Kraup, Sabina January 2010 (has links)
The purpose of this study is to examine the medial depiction of Muslims in the case of Pastor Terry Jones' intention to burn the Quran. Our study is based on theoretical framework regarding an alleged clash of civilizations, how that leads to global conflicts and controls the world politics. It’s also based on the western way of characterize Muslims as violent, irrational human beings, and how mass media have a tendency to depict Muslims as “the others”. The questions we aim to seek answers to are: How were Muslims portrayed in CNN's and Al-Jazeera's reporting regarding Terry Jones plan to burn the Quran? Which discourses exist about Muslims in each news channel and what are the main differences between them? The qualitative method used is a critical discourse analysis on empirical data consistently of twelve articles. A profound thematic and schematic analysis of each article is applied in order to make interpretations and relate the result to our theoretical framework. The result of the study shows that Muslims are, to a high level, portrayed as violent or dangerous with a strong connection to terrorism. A slight difference existed in the themes and discourses between each news channel. CNN objectified Muslims, as a whole, as a safety threat to the western community when Al-Jazeera, on the other hand, had the similar portraytion, but with an explanatory approach.

FlockViz: A Visualization Technique to Facilitate Multi-dimensional Analytics of Spatio-temporal Cluster Data

Hossain, Mohammad Zahid 26 May 2014 (has links)
Visual analytics of large amounts of spatio-temporal data is challenging due to the overlap and clutter from movements of multiple objects. A common approach for analyzing such data is to consider how groups of items cluster and move together in space and time. However, most methods for showing Spatio-temporal Cluster (STC) properties, concentrate on a few dimensions of the cluster (e.g. the cluster movement direction or cluster density) and many other properties are not represented. Furthermore, while representing multiple attributes of clusters in a single view existing methods fail to preserve the original shape of the cluster or distort the actual spatial covering of the dataset. In this thesis, I propose a simple yet effective visualization, FlockViz, for showing multiple STC data dimensions in a single view by preserving the original cluster shape. To evaluate this method I develop a framework for categorizing the wide range of tasks involved in analyzing STCs. I conclude this work through a controlled user study comparing the performance of FlockViz with alternative visualization techniques that aid with cluster-based analytic tasks. Finally the exploration capability of FlockViz is demonstrated in some real life data sets such as fish movement, caribou movement, eagle migration, and hurricane movement. The results of the user studies and use cases confirm the advantage and novelty of the novel FlockViz design for visual analytic tasks.

Partimos da premissa teórica de que relevância é mensurável e adotamos o princípio metodológico de que uma maior freqüência lexical encontra-se hipoteticamente associada a um maior peso relativo e relevância conceituais dentro de um conjunto de termos , aplicando-o na análise de conteúdo de 305 textos de quatro agências de notícia transnacionais a francesa France Presse (AFP), a americana Associated Press (AP), a espanhola EFE e a britânica/canadense Reuters em duas eleições presidenciais brasileiras. Neste corpus, coletado via telex, em 1989, e na internet, em 2010, identificamos os tipos de termo usados pelas quatro agências em função adjetiva antes, depois e em substituição ao nome dos quatro principais candidatos em cada eleição, mapeamos os esquemas de classificação política de cada uma e comparamos os critérios de relevância aplicados nos dois momentos, em busca de regularidades e discrepâncias que corroborassem, ou não, a hipótese de que agências de notícia transnacionais recorrem a esquemas de classificação próprios baseados numa tipologia comum de termos, cuja frequência no corpus revela os critérios de relevância de cada uma. Com base nos resultados, concluímos que os critérios de relevância das agências pesquisadas são semelhantes em diversos aspectos aos critérios adotados por usuários de sistemas de informação ao inferirem relevância em processos de busca

Atomic decompositions and frames in Fréchet spaces and their duals

Ribera Puchades, Juan Miguel 11 May 2015 (has links)
[EN] The Ph.D. Thesis "Atomic decompositions and frames in Fréchet spaces and their duals" presented here treats different areas of functional analysis with applications. Schauder frames are used to represent an arbitrary element x of a function space E as a series expansion involving a fixed countable set {xj} of elements in that space such that the coefficients of the expansion of x depend in a linear and continuous way on x. Unlike Schauder bases, the expression of an element x in terms of the sequence {xj}, i.e. the reconstruction formula for x, is not necessarily unique. Atomic decompositions or Schauder frames are a less restrictive structure than bases, because a complemented subspace of a Banach space with basis has always a natural Schauder frame, that is obtained from the basis of the superspace. Even when the complemented subspace has a basis, there is not a systematic way to find it. Atomic decompositions appeared in applications to signal processing and sampling theory among other areas. Very recently, Pilipovic and Stoeva [55] studied series expansions in (countable) projective or inductive limits of Banach spaces. In this thesis we begin a systematic study of Schauder frames in locally convex spaces, but our main interest lies in Fréchet spaces and their duals. The main difference with respect to the concept considered in [55] is that our approach does not depend on a fixed representation of the Fréchet space as a projective limit of Banach spaces. The text is divided into two chapters and appendix that gives the notation, definitions and the basic results we will use throughout the thesis. The first one focuses on the relation between the properties of an existing Schauder frame in a Fréchet space E and the structure of the space. In the second chapter frames and Bessel sequences in Fréchet spaces and their duals are defined and studied. In what follows, we give a brief description of the different chapters: In Chapter 1, we study Schauder frames in Fréchet spaces and their duals, as well as perturbation results. We define shrinking and boundedly complete Schauder xviiframes on a locally convex space, study the duality of these two concepts and their relation with the reflexivity of the space. We characterize when an unconditional Schauder frame is shrinking or boundedly complete in terms of properties of the space. Several examples of concrete Schauder frames in function spaces are also presented. Most of the results included in this chapter are published by Bonet, Fernández, Galbis and Ribera in [13]. The second chapter of the thesis is devoted to study ¿-Bessel sequences, ¿-frames and frames with respect to ¿ in the dual of a Hausdorff locally convex space E, in particular for Fréchet spaces and complete (LB)-spaces E, with ¿ a sequence space. We investigate the relation of these concepts with representing systems in the sense of Kadets and Korobeinik [34] and with the Schauder frames, that were investigated in Chapter 1. The abstract results presented here, when applied to concrete spaces of analytic functions, give many examples and consequences about sampling sets and Dirichlet series expansions. We present several abstract results about ¿-frames in complete (LB)-spaces. Finally, many applications, results and examples concerning sufficient sets for weighted Fréchet spaces of holomorphic functions and weakly sufficient sets for weighted (LB)-spaces of holomorphic functions are collected. Most of the results are submitted for publication in a preprint of Bonet, Fernández, Galbis and Ribera in [12]. / [ES] La presente memoria "Descomposiciones atómicas y frames en espacios de Fréchet y sus duales" trata diferentes áreas del análisis funcional con aplicaciones. Los frames de Schauder se utilizan para representar un elemento arbitrario x de un espacio de funciones E mediante una serie a partir de un conjunto numerable fijado {xj} de elementos de este espacio de manera que los coeficientes de la reconstrucción de x dependen de forma lineal y continua de x. A diferencia de las bases de Schauder, la expresión de un elemento x en términos de la sucesión {xj}, i.e. la fórmula de reconstrucción para x, no es necesariamente única. Las descomposiciones atómicas o los frames de Schauder son un estructura menos restrictiva que las bases, porque un subespacio complementado de un espacio de Banach con base tiene siempre un frame de Schauder natural, que se obtiene a partir de una base del superespacio. Incluso cuando el subespacio complementado tiene una base, no hay una forma sistemática de encontrarla. Las descomposiciones atómicas aparecen en aplicaciones al procesamiento de señales y la teoría de muestreo, entre otras áreas. Recientemente, Pilipovic y Stoeva [55] han estudiado el desarrollo en serie en límites inductivos y proyectivos (numerables) de espacios de Banach. En esta tesis empezamos un estudio sistemático de los frames de Schauder en espacios localmente convexos aunque nuestro interés principal son los espacios de Fréchet y sus duales. La diferencia principal respecto del concepto considerado en [55] es que nuestra aproximación no depende de una representación fijada del espacio de Fréchet como límite proyectivo de espacios de Banach. El texto queda dividido en dos partes y un apéndice que incluye la notación, las definiciones y los resultados básicos que usaremos a lo largo de la tesis. La primera parte se centra en la relación entre las propiedades de un frame de Schauder en un espacio de Fréchet E y la estructura del espacio. En el segundo capítulo se definen y estudian los frames y las sucesiones de Bessel en espacios de Fréchet y sus duales. A continuación, presentamos una breve descripción de los capítulos: En el Capítulo 1, estudiamos los frames de Schauder en los espacios de Fréchet y sus duales así como los resultados de perturbación. Definimos los frames de Schauder contractivos y acotadamente completos en espacios localmente convexos, estudiamos la dualidad de estos dos conceptos y su relación con la reflexividad del espacio. Caracterizamos cuándo un frame de Schauder incondicional es contractivo o acotadamente completo en términos de las propiedades del espacio. También se presentan varios ejemplos de frames de Schauder en espacios de funciones concretos. La mayoría de los resultados incluidos en este capítulo están publicados por Bonet, Fernández, Galbis y Ribera en [13]. El segundo capítulo de la tesis está centrado en el estudio de las sucesiones de ¿-Bessel, ¿-frames y frames respecto de ¿ en el dual de un espacio localmente convexo de Hausdorff E, en particular, para espacios de Fréchet y espacios (LB) completos E, con ¿ un espacio de sucesiones. Investigamos la relación de estos dos conceptos con los sistemas representantes en el sentido de Kadets y Korobeinik [34] y con los frames de Schauder, considerados en el Capítulo 1. Los resultados abstractos presentados aquí, cuando los aplicamos a espacios de funciones analíticas concretos, nos dan muchos ejemplos y consecuencias sobre los conjuntos de muestreo y los desarrollos en serie de Dirichlet. Presentamos varios resultados abstractos sobre ¿-frames en espacios (LB) completos. Finalmente, recogemos muchas aplicaciones, resultados y ejemplos alrededor de los conjuntos suficientes para espacios de Fréchet de funciones holomorfas y conjuntos débilmente suficientes para espacios pesados (LB) de funciones holomorfas. La mayoría de los resultados incluidos en este capítulo están enviados para publicar e / [CA] La tesi "Descomposicions atòmiques i frames en espais de Fréchet i els seus duals" presentada ací tracta diferents àrees de l'anàlisi funcional amb aplicacions. Els frames de Schauder s'utilitzen per tal de representar un element arbitrari x d'un espai de funcions E com una reconstrucció en sèrie a partir d'un conjunt numerable fixat {xj} d'elements en aquest espai tal que els coeficients de la reconstrucció de x depenen de forma lineal i continua de x. A diferència de les bases de Schauder, l'expressió d'un element x en termes d'una successió {xj}, i.e. la fórmula de reconstrucció per a x, no és necessàriament única. Les descomposicions atòmiques o els frames de Schauder són una estructura menys restrictiva que les bases, donat que un subespai complementat d'un espai de Banach amb base sempre té un frame de Schauder natural, el qual és obtingut a partir d'una base del superespai. Inclòs quan el subespai complementat disposa de una base, no hi ha una forma sistemàtica per tal de trobar-la. Les descomposicions atòmiques apareixen en aplicacions a processat de senyals i teoría de mostreig entre altres àrees. Recentment, Pilipovic i Stoeva [55] han estudiat els desenvolupaments en sèrie en límits inductius o projectius (numerables) en espais de Banach. En aquesta tesi comencem un estudi sistemàtic dels frames de Schauder en espais localment convexos, tot i que el nostre interés està en els espais de Fréchet i els seus duals. La diferència més important amb el concepte estudiat en [55] és que el nostre estudi no depén de una representació fixada del espai de Fréchet com a límit projectiu de espais de Banach. El text està dividit en dos capítols i un apèndix que ens aporta la notació, definicions i els resultats bàsics que utilitzarem al llarg de la tesi. El primer dels capítols està centrat en la relació entre les propietats de un frame de Schauder en un espai de Fréchet E i la estructura del espai. En el segon capítol es defineixen i estudien els frames i les successions de Bessel en espais de Fréchet i els seus duals. En el que segueix, donem una breu descripció dels diferents capítols: En el Capítol 1, estudiem els frames de Schauder en els espais de Fréchet i els seus duals, així com els resultats de pertorbació. Definim els frames de Schauder contractius i fitadament complets en espais localment convexos, estudiem la dualitat d'aquests dos conceptes i la seua relació amb la reflexivitat del espai. Caracteritzem, en quines situacions, un frame de Schauder incondicional és contractiu o fitadament complet en termes de les propietats del espai. També presentem alguns exemples de frames de Schauder concrets en espais de funcions. La majoria dels resultats inclosos en aquest capítol estan publicats per Bonet, Fernández, Galbis i Ribera en [13]. El segon capítol de la tesi està centrat en el estudi de les successions ¿-Bessel, ¿-frames i frames respecte de ¿ en el dual d'un espai localment convex de Hausdorff E, en particular, per a espais de Fréchet i espais (LB) complets E, amb ¿ un espai de successions. Investiguem la relació d'aquests dos conceptes amb sistemes representants en el sentit de Kadets i Korobeinik [34] i amb els frames de Schauder, que han sigut investigats en el Capítol 1. Els resultats abstractes presentats ací, quan els apliquem a espais de funcions analítiques concrets, ens donen molts exemples i conseqüències sobre els conjunts de mostreig i els desenvolupaments en sèrie de Dirichlet. Presentem diversos resultats abstractes sobre ¿-frames en espais (LB) complets. Finalment, recollim moltes aplicacions, resultats i exemples al voltant dels conjunts suficients per a espais de Fréchet de funcions holomorfes i conjunts dèbilment suficients per a espais pesats (LB) de funcions holomorfes. La majoria dels resultats inclosos en aquest capítol estan sotmesos a publicació per Bonet, Fernández, Galbis i Ribera en [12]. / Ribera Puchades, JM. (2015).

Information model for representing people’s needs in charity organizations work in Saudi Arabia : towards a user-oriented evaluation / Un modèle d'information pour représenter les besoins des personnes dans les organisations de charité travaille en Arabie Saoudite : vers une évaluation axée sur l'utilisateur

Al Othman, Ahmed Mohammad 04 December 2017 (has links)
L'objectif de cette étude est de développer un modèle d'information pour représenter les besoins des personnes dans les organismes de bienfaisance de l'Arabie Saoudite. La population cible sont les organismes de bienfaisance qui s'intéressent à la collecte et à la distribution des dons à leurs électeurs.Le but de cette étude est atteint par trois objectifs ; Le premier objectif est d'identifier l'état actuel de l'utilisation des systèmes d'information dans le secteur des organismes de bienfaisance. Le deuxième objectif est d'identifier les besoins d'information de ces organismes de charité à l'égard de leurs bénéficiaires.. En utilisant la théorie des sens et son ensemble de méthodes, nous avons pu comprendre les besoins informatiques du point de vue des utilisateurs eux-mêmes. Le troisième objectif est de faire correspondre les besoins résultant des besoins d'information des organismes de charité avec les dimensions des besoins de développement humain par Narayan et al., (2000) qui a été étudié pour informer le rapport sur le Développement Mondial de la Pauvreté et du Développement. Cette étude est significative parce qu'elle n'a pas été menée dans cette échelle ou cette portée avant, et elle fournit une image claire de l'état actuel de l'utilisation des systèmes d'information dans le secteur, elle fournit également un modèle de recherche éclairé qui aidera à mieux répondre aux besoins des personnes pauvres inscrites dans ces organismes de bienfaisance. Le modèle de besoins d'information résultant de cette étude fournit un élément précieux pour un système d'information futur, basé sur des données de recherche visant à améliorer l'efficacité, la fiabilité et la responsabilité dans la gestion des dons pour le bien-être du constituant.Les données de cette recherche ont été recueillies au moyen de deux études, la première étude a porté sur l'ensemble de la population d'organismes de bienfaisance par le biais d'un sondage électronique et le nombre de cas au final était de 83 organismes de bienfaisance. Cette étude visait à étudier l'état actuel de l'utilisation des systèmes d'information dans les organismes de bienfaisance, les interrogés ont répondu à 18 questions divisées en quatre sections. La première section portait sur le profil de l'organisation. La deuxième concerne les systèmes d'information pour les bénéficiaires. et les dons. La troisième concerne les bénéficiaires. Le quatrième, était une information supplémentaire sur l'adaptation des SI futurs. La deuxième étude a été une entrevue avec 15 organismes de bienfaisance de la région de Riyad. Ils comprenaient des organismes de bienfaisance masculins et féminins, et des organismes de bienfaisance de différentes localités comme le village et la petite ville. Cette étude a utilisé la théorie des sens de Brenda Dervin pour étudier les besoins d'information duPage 2 sur 2point de vue de l'utilisateur à l'organisme de bienfaisance en ce qui concerne les bénéficiaires. et les dons. Les entrevues ont été menées face à face avec chaque cas dans la deuxième étude.Les résultats de cette recherche montrent que l'utilisation des systèmes d'information dans les organismes de bienfaisance est répandue, avec 89,2% des organismes de bienfaisance utilisant un SI dans certains ou tous les processus de travail. Il a également révélé la diversité des processus dans lesquels les organismes de bienfaisance employés SI, comprenant 4 thèmes majeurs et 22 processus de travail distincts. Il a également révélé que les besoins d'information des organismes de charité ont sept ensembles distincts, et chaque ensemble comprend entre 2 et 19 lacunes en matière d'information. Les résultats montrent également que les besoins d'information des organismes de bienfaisance ont une grande couverture des dimensions de bien-être du rapport sur le développement mondial de 2000/2001, couvrant une couverture de 50% à 100%. / The aim of this study is to develop an information model for representing people’s needs in charity organizations of Saudi Arabia. The target population are the charity organizations that are concerned with donations gathering and distribution to their constituents.The aim of this study is achieved through three objectives; the first objective is to identify the current state of information systems use in the sector of charity organizations. The second objective is to identify the information needs of those charity organizations with regard to their constituents. By using the sense-making theory and its set of methods, we were able to understand the informational needs from the perspective of the users themselves. The third objective is to match the resulting sets of informational needs of charity organizations with the dimensions of human development needs by Narayan et al., (2000) which was researched to inform the World Development report on Poverty and Development. This study is significant because it was not conducted in that scale or scope before, and it provides a clear picture of the current state of information systems use in the sector, it also provides a research informed model, which will help better fulfill the needs of the poor people registered at those charities. The information needs model resulting from this study provides a valuable building block for a future information system, which is based on research data to improve efficiency, reliability and accountability in donations management for the wellbeing of the constituent.The data for this research was collected through two studies, the first study was targeted at the whole population of charity organizations through an electronic survey, and the final case number was 83 charities. This study aimed at investigating the current state of information systems use at charity organizations, respondents answered 18 questions divided in four sections. The first section was about the organization’s profile. The second was about information systems for constituents and donations. The third was about the constituents. The fourth, was additional information about adaptation of future IS. The second study was an interview with 15 charity organizations from Riyadh region. They included masculine and feminine charities, and charities of different localities such as village and small-city. This study used the sense-making theory byPage 2 of 2Brenda Dervin to investigate the information needs from the user’s perspective at the charity with regard to constituents and donations. The interviews were conducted face-to-face with each single case in the second study.The results of this research show that the use of information systems at charities is widespread, with 89.2% of charities using an IS in some or all work processes. It also revealed the diversity of processes in which charities employee IS, comprising 4 major themes and 22 distinct work processes. It also revealed that the information needs of charity organizations has seven distinct sets, and each set included between 2 and 19 information gaps. The results also show that the information needs of charities has a great coverage of the wellbeing dimensions of the World Development report of 2000/2001, spanning from 50% to 100% coverage. It also revealed that the number of all information sources, which could bridge the information gaps, are 18 sources spread across five sectors in the country.The information needs model for representing people’s needs was a result of the combination and analysis of all research findings to develop that model. It has nine dimensions of information and its corresponding data inputs, leading to the desired knowledge about the constituent. The model covers all aspects of the life of the constituent and can be modified by individual charities to satisfy their own objectives and to lead to new and relevant knowledge.

Výstava versus výstavnictví. Československé pavilony na Expo 1967 v Montrealu a Expo 1970 v Ósace / Exhibition versus "exhibitioning". The Czechoslovak pavilions at Expo 1967 in Montreal and Expo 1970 in Osaka

The paper focuses on the Czechoslovak pavilions at the 1967 and 1970 World Expos. Both events took place in the period around 1968, when, however briefly, the Czechoslovak visual arts partially overlapped with the state's cultural policy. The pavilions (especially at Expo 70) also reflected the socio- political contexts of the year 1968.. In Czechoslovakia towards the end of the 1960s, the purpose of "exhibitioning" - i.e., the state-sponsored exhibition trade - was to communicate with the public and to (re)present the country abroad. Its main goal was to promote and spread the ruling ideology. On the other hand, the Czechoslovak visual arts scene was beginning to consciously work with the medium of the exhibition as a comprehensively composed unit, either through innovative exhibition design and installation or through installation art. While the exhibition trade reached its high point in the 1960s and began to disintegrate into rigid mannerism towards the end of the decade, real experiments with the format of the art exhibition were just beginning. This study focuses on the question of how these two fields (art and the exhibition trade) approached the medium of the exhibition in the 1960s. I study the Czechoslovak pavilions as a cultural artifact in which aesthetic, social, political, and economic forces...
