Denna uppsats undersöker i vilken utsträckning fyra utvalda medier följer riktlinjer för publicering av opinionsmätningar som de internationella branschorganisationerna World Association for Public Opinion Research (WAPOR) och The European Society for Opinion and Marketing Research (ESOMAR) gemensamt tagit fram. Riktlinjerna som undersöks i studien handlar om opinionsmätningens metod och den nödvändiga informationen som bör tillgängliggöras i samband med publiceringen av opinionsmätningar. Dvs. den statistiska basinformationen som är nödvändig för läsarna att ta del av för att kunna göra en bedömning av mätningens trovärdighet.   Med hjälp av en kvantitativ metod har artiklar med koppling till opinionsmätningar som publicerats av Aftonbladet, Expressen, Svenska dagbladet och Dagens nyheter, i oktober 2017, granskats.   De teorier som främst berörs i uppsatsen är objektivitetsteorin och gestaltningsteorin. Resultatet visar att samtliga tidningar har stora brister i att följa organisationernas rekommendationer för publicering av opinionsmätningar.

The use of mobile ad-hoc networks (MANETs) is growing. The issue of security in MANETs is not trivial, since such networks have no fixed infrastructure and therefor centralised security is not applicable. MANETs are also more sensitive to attacks due to their wireless communication channels and their spontaneous nature. All kind of cooperation requires a sense of trust. The opinion about trust in other entities can be used as a mean to dynamically allow for secure cooperation in MANETs, as soft security. And also to counter some of the inherited security problems of MANETs. To use opinions as a security paradigm in MANETs the opinions about other nodes has to be spread as reputation about a node. This reputation spreading can be done through spreading of opinions or the spreading of evidences about a nodes behaviour. In this work evidence and reputation spreading are compared to each other. This comparison shows that they are quite similar from a security point of view but that they differ in scalability.

Ce mémoire propose une étude sur le texte Correspondance de quelques gens du monde sur les affaires du tems publié à Paris en 1790, c’est-à-dire au début de la Révolution française. L’approche choisie permet de s’intéresser à la présence de personnages fictifs, mais vraisemblables, dans le cadre de la transmission d’un discours journalistique entre Paris et la province. Il s’agit, en outre, de mieux comprendre les formes textuelles utilisées pour la mise en récit des nouvelles et la mise en scène de débats d’opinions. Cette recherche tente aussi de saisir comment l’auteur conçoit l’opinion publique et comment il l’emploie pour influencer ses lecteurs et ses lectrices. Enfin, l’utilisation de personnages permet de donner un sens à la transmission qui s’opère entre l’écrivain et son lectorat.

Ingeniero Civil Industrial / Los contenidos disponibles en la Web están creciendo a velocidades que hacen que la tarea de analizarlos sea humanamente imposible. Una de las disciplinas que hace frente a este problema es la Minería de Opiniones, también conocida como el Análisis de Sentimientos, responsable de procesar texto automáticamente, con el fin de extraer y analizar las opiniones que contiene para generar información valiosa y accionable. El objetivo principal de este trabajo es crear una aplicación de Minería de Opiniones capaz de explotar tweets en español que mencionen a la empresa de retail Falabella. En primer lugar, se investigó el impacto que las redes sociales tienen en Chile. En segundo lugar, se elaboró un estado del arte que englobara los últimos avances en Minería de Opiniones y en Procesamiento del Lenguaje Natural. En tercer lugar, se creó un Web Crawler capaz de obtener los tweets que mencionanaran a la compañía. Posteriormente se implementó varios algoritmos de Procesamiento del Lenguaje Natural para pre-procesar los tweets previamente mencionados, e incorporar los datos resultantes al proceso de extracción de opiniones. Este proceso se desarrolló como un enfoque de Minería de Opiniones no supervisado basado en lexicones, dependiente de un analizador de dependencias encargado de detectar ciertas estructuras gramaticales que permitieran identificar fenómenos linguísticos comunes, tales como la negación, intensificación, y oraciones subordinadas adversativas. La identificación de dichos fenómenos permitió mejorar la calidad de la clasificación. Finalmente se creó una página Web para mostrar los resultados que luego fueron utilizados para realizar un análisis exploratorio de la compañía. Adicionalmente, los algoritmos fueron validados con el corpus TASS, obteniendo valores-F de un 61,88% negativo y 71,88% positivo. A pesar de que el rendimiento de los algoritmos no fue tan alto como una aplicación en producción lo requeriría, se consideró lo suficientemente bueno como para realizar el análisis exploratorio. Con éste fue posible confirmar la intuición de que las cuentas corporativas suelen publicar contenido positivo, las cuentas de noticias contenido neutral, y los usuarios comunes contenido irrelevante o quejas. Además fue posible probar que los usuarios más activos frecuentemente publican contenido totalmente irrelevante. Por otra parte, se logró replicar varios resultados obtenidos por instituciones nacionales reconocidas, entre los cuales destaca el hecho que el momento más controversial del año para Falabella fue cuando se intentó llevar a cabo el Cyber Monday, período en el cual el sentimiento generalizado en Twitter alcanzó los niveles más negativos. Dicho todo esto, la aplicación desarrollada demostró ser útil al momento de utilizar una gran cantidad de datos para extraer información que podría ser potencialmente útil para la firma de retail. Finalmente, el desarrollo de la aplicación permitió crear un artículo que contuviera parte considerable del transfondo teórico en el cual ésta se basó, además de beneficiar a otros estudiantes en el desarrollo de sus memorias.

The “camera eats first” phenomenon has become a worldwide popular culture which affects our everyday life. The study is committed to look at the foodie behavior on Instagram in Hong Kong, a renowned gourmet paradise. Through a qualitative study of five Instagram foodies, it aims to explore and add an academic dimension of understanding of the culture from the foodie’s perspective and their online behaviors of running a public profile about daily food consumption on Instagram. The results suggested that some foodies see their profiles as the extension of themselves, a space to showcase their works and preferences; but they do not see their profile as a future business opportunity. Even though the foodies on Instagram are mostly amateur instead of professionally trained food photographers, they keep enhancing their skills by learning from their peers and constant practices, for the sake of producing attractive photos. Flat-lay is one of the most popular styles of photography on Instagram which is appreciated by the foodies, as well as the audience. Attractive food visual content and skillful labeling hashtags have made Instagram a platform to satisfy intense desire for food consumption. A foodie’s interaction with audience further enhances the consumer’s desire by offering personal comments. The findings imply that there is a wide scale of foodies with different attitudes towards their practice of posting food images on Instagram. It is crucial for food marketers to understand their attitudes and preferences for better communication. Future research can be conducted on a broader scale of foodies to examine foodies and their influence on social class, giving marketers more ideas of effective positioning and segmentation.

The purpose of this study was to find out whether factors such as the learners’ learning styles, their cultural backgrounds, instructional approaches and strategies used by teachers and the lack of exposure to relevant resources had an influence on the declining English proficiency among learners. The researcher is currently an English teacher in one of the schools in the Qumbu Education District. The researcher expressed concern about the learners’ declining performance in aspects of English language like reading, writing and speaking. The idea of carrying out this study became necessary as English is a compulsory first additional language for most of the schools. Most of the subjects offered in South African schools are taught in English; moreover, English is an internationally-recognized medium of communication. One therefore, has to master the use of English to a certain extent so as to be a successful scholar. The sample consisted of 20 English senior phase teachers who were randomly selected from 13 schools in various circuits around the Qumbu Education District. Data was collected through the use of questionnaires which focused specifically on the learners’ learning styles, their cultural backgrounds, instructional approaches and strategies used by teachers, and also the lack of exposure to relevant literature. These questionnaires were administered by the researcher in person. The data were analyzed and interpreted statistically and also presented through tables and discussions. The findings of this study revealed that the geographical locations of the selected schools for the research study, limited exposure to English-related resources, workload of English teachers, teaching and learning approaches, and knowledge acquisition strategies employed by teachers and learners contribute to the decline in English proficiency among the learners. If these could be attended to effectively, English proficiency could improve among learners. In conclusion, recommendations have been made both for action and possible further research.
