S'hi estudia el paper dels mitjans de comunicació en el sistema democràtic i la manera com la deontologia pot ajudar a pal·liar alguns dels abusos o desviacions de l'ètica que hauria de presidir el comportament de periodistes i mitjans. També s'hi analitza el control que cal establir sobre aquests protagonistes davant l'actual concentració d'empreses de comunicació.

International images and mass media: The effects of media coverage on Canadians' perceptions of ethnic and race relations in Australia

Recently, there has been much speculation about the impact of international media coverage of Australia's position on Indigenous people, migrants and asylum seekers on other nations' images of Australia. In this experiment we examined whether there was any basis for such concerns by considering the short-term impact of negative TV coverage of Australians on Canadian viewers. A questionnaire provided baseline data on Canadian students' perceptions of Australians and Australian race relations. Four months later, the students were assigned to one of three conditions that varied media contact with Australians. Students viewed one of two television programs (about right-wing political independent, Pauline Hanson, and her emotive criticisms of Aborigines and Asian immigrants or about an ethnically-mixed group of young Australians and their positive sense of cultural identity), or they viewed no program (no contact control). Results indicated that both positive and negative media coverage of Australians affected Canadians' views of Australia in the short-term. In particular, negative coverage (of Hanson) promoted less favourable views of Australians and Australian race relations over time and relative to the positive media and no media control conditions. The media's role in shaping international images is discussed.

Insatisfação corporal e as influencias dos meios de comunicação face à aparência, controlo do peso e obesidade

RESUMO: O objectivo deste estudo é identificar o índice da insatisfação corporal e as influências dos meios de comunicação nas atitudes da mulher face á mudança da aparência, controlo do peso e Obesidade. Pretende-se com este estudo caracterizar e relacionar o índice de insatisfação corporal e a influência exercida pelos meios de comunicação social, fazendo um estudo com base nas diferenças entre dois grupos, numa amostra de 118 participantes do sexo feminino. A amostra de conveniência é composta por 59 mulheres diagnosticadas com obesidade mórbida grau III e grau IV, acompanhada no Serviço de Obesidade do Hospital de Santa Maria e numa amostra de 59 mulheres sem o diagnóstico de obesidade mórbida, com idades compreendidas entre os 19 e os 72 anos. O Protocolo de avaliação foi constituído por um questionário com recolhas dos dados demográficos e métodos utilizados pela mulher para o controlo do peso e duas escalas Sociocultural Attitudes Towards Appearance Questionnaire 3 e Body Shape Questionnaire. Verificou-se uma elevada insatisfação corporal e influências dos meios de comunicação no grupo clínico. Foi verificado ainda que a faixa etária das mulheres entre os 26 aos 39 anos são as que mais sofrem influências dos meios de comunicação face as atitudes para mudar a aparência. ABSTRACT: The objective of this study is to identify the index of body dissatisfaction and the influences of media on women's attitudes will change the face looks. It is intended to characterize the study and associate the index of body dissatisfaction and the influences exerted by the media, control and obesity. Doing a study based on the differences between two groups, a sample of 118 participants were female, the non-random sample consisted by 59 women diagnosed with morbid obesity level III and Grade IV, monitored in the Office of Obesity, Hospital de Santa Maria and a random sample of 59 women without a diagnosis of morbid obesity aged between 19 and 72 years. The Protocol of evaluation was made of a questionnaire with collections of demographic data and methods used by women for weight control and two scales Sociocultural Attitudes Towards Appearance Questionnaire 3 and Body Shape Questionnaire. There was high body dissatisfaction and influences of the media in the clinical group. It was also verified that the age group of women among the 26 to 39 years who are suffering most are the influences of the media to change attitudes towards the dark.

A peptide inhibitor of c-Jun N-terminal kinase for the treatment of endotoxin-induced uveitis.

PURPOSE: To evaluate the effect of XG-102 (formerly D-JNKI1), a TAT-coupled dextrogyre peptide that selectively inhibits the c-Jun N-terminal kinase, in the treatment of endotoxin-induced uveitis (EIU). METHODS: EIU was induced in Lewis rats by LPS injection. XG-102 was administered at the time of LPS challenge. The ocular biodistribution of XG-102 was evaluated using immunodetection at 24 hours after either 20 microg/kg IV (IV) or 0.2 microg/injection intravitreous (IVT) administrations in healthy or uveitic eyes. The effect of XG-102 on EIU was evaluated using clinical scoring, infiltration cell quantification, inducible nitric oxide synthase (iNOS) expression and immunohistochemistry, and cytokines and chemokines kinetics at 6, 24, and 48 hours using multiplex analysis on ocular media. Control EIU eyes received vehicle injection IV or IVT. The effect of XG-102 on c-Jun phosphorylation in EIU was evaluated by Western blot in eye tissues. RESULTS: After IVT injection, XG-102 was internalized in epithelial cells from iris/ciliary body and retina and in glial and microglial cells in both healthy and uveitic eyes. After IV injection, XG-102 was concentrated primarily in inflammatory cells of uveitic eyes. Using both routes of administration, XG-102 significantly inhibited clinical signs of EIU, intraocular cell infiltration, and iNOS expression together with reduced phosphorylation of c-Jun. The anti-inflammatory effect of XG-102 was mediated by iNOS, IFN-gamma, IL-2, and IL-13. CONCLUSIONS: This is the first evidence that interfering with the JNK pathway can reduce intraocular inflammation. Local administration of XG-102, a clinically evaluated peptide, may have potential for treating uveitis.

Sistema domótico controlado por mensajería instantánea Whatsapp para personas con discapacidad

El presente PFC tiene como objetivo el desarrollo de un gestor domótico basado en el dictado de voz de la red social WhatsApp. Dicho gestor no solo sustituirá el concepto dañino de que la integración de la domótica hoy en día es cara e inservible sino que acercará a aquellas personas con una discapacidad a tener una mejora en la calidad de vida. Estas personas, con un simple comando de voz a su aplicación WhatsApp de su terminal móvil, podrán activar o desactivar todos los elementos domóticos que su vivienda tenga instalados, “activar lámpara”, “encender Horno”, “abrir Puerta”… Todo a un muy bajo precio y utilizando tecnologías OpenSource El objetivo principal de este PFC es ayudar a la gente con una discapacidad a tener mejor calidad de vida, haciéndose independiente en las labores del hogar, ya que será el hogar quien haga las labores. La accesibilidad de este servicio, es por tanto, la mayor de las metas. Para conseguir accesibilidad para todas las personas, se necesita un servicio barato y de fácil aprendizaje. Se elige la red social WhatsApp como interprete, ya que no necesita de formación al ser una aplicación usada mayoritariamente en España y por la capacidad del dictado de voz, y se eligen las tecnologías OpenSource por ser la gran mayoría de ellas gratuitas o de pago solo el hardware. La utilización de la Red social WhatsApp se justifica por sí sola, en septiembre de 2015 se registraron 900 millones de usuarios. Este dato es fruto, también, de la reciente adquisición por parte de Facebook y hace que cumpla el primer requisito de accesibilidad para el servicio domotico que se presenta. Desde hace casi 5 años existe una API liberada de WhatsApp, que la comunidad OpenSource ha utilizado, para crear sus propios clientes o aplicaciones de envío de mensajes, usando la infraestructura de la red social. La empresa no lo aprueba abiertamente, pero la liberación de la API fue legal y su uso también lo es. Por otra parte la empresa se reserva el derecho de bloquear cuentas por el uso fraudulento de su infraestructura. Las tecnologías OpenSource utilizadas han sido, distribuciones Linux (Raspbian) y lenguajes de programación PHP, Python y BASHSCRIPT, todo cubierto por la comunidad, ofreciendo soporte y escalabilidad. Es por ello que se utiliza, como matriz y gestor domotico central, una RaspberryPI. Los servicios que el gestor ofrece en su primera versión incluyen el control domotico de la iluminación eléctrica general o personal, el control de todo tipo de electrodomésticos, el control de accesos para la puerta principal de entrada y el control de medios audiovisuales. ABSTRACT. This final thesis aims to develop a domotic manager based on the speech recognition capacity implemented in the social network, WhatsApp. This Manager not only banish the wrong idea about how expensive and useless is a domotic installation, this manager will give an opportunity to handicapped people to improve their quality of life. These people, with a simple voice command to their own WhatsApp, could enable or disable all the domotics devices installed in their living places. “On Lamp”, “ON Oven”, “Open Door”… This service reduce considerably the budgets because the use of OpenSource Technologies. The main achievement of this thesis is help handicapped people improving their quality of life, making independent from the housework. The house will do the work. The accessibility is, by the way, the goal to achieve. To get accessibility to a width range, we need a cheap, easy to learn and easy to use service. The social Network WhatsApp is one part of the answer, this app does not need explanation because is used all over the world, moreover, integrates the speech recognition capacity. The OpenSource technologies is the other part of the answer due to the low costs or, even, the free costs of their implementations. The use of the social network WhatsApp is explained by itself. In September 2015 were registered around 900 million users, of course, the recent acquisition by Facebook has helped in this astronomic number and match the first law of this service about the accessibility. Since five years exists, in the internet, a free WhatsApp API. The OpenSource community has used this API to develop their own messaging apps or desktop-clients, using the WhatsApp infrastructure. The company does not approve officially, however le API freedom is legal and the use of the API is legal too. On the other hand, the company can block accounts who makes a fraudulent use of his infrastructure. OpenSource technologies used in this thesis are: Linux distributions (Raspbian) and programming languages PHP, Python and BASHCSRIPT, all of these technologies are covered by the community offering support and scalability. Due to that, it is used a RaspberryPI as the Central Domotic Manager. The domotic services that currently this manager achieve are: Domotic lighting control, electronic devices control, access control to the main door and Media Control.

Error estimate and control in the MSFV method for multiphase flow in porous media

n this paper the iterative MSFV method is extended to include the sequential implicit simulation of time dependent problems involving the solution of a system of pressure-saturation equations. To control numerical errors in simulation results, an error estimate, based on the residual of the MSFV approximate pressure field, is introduced. In the initial time steps in simulation iterations are employed until a specified accuracy in pressure is achieved. This initial solution is then used to improve the localization assumption at later time steps. Additional iterations in pressure solution are employed only when the pressure residual becomes larger than a specified threshold value. Efficiency of the strategy and the error control criteria are numerically investigated. This paper also shows that it is possible to derive an a-priori estimate and control based on the allowed pressure-equation residual to guarantee the desired accuracy in saturation calculation.

Periodic forcing of scroll rings and control of Winfree turbulence in excitable media

By simulations of the Barkley model, action of uniform periodic nonresonant forcing on scroll rings and wave turbulence in three-dimensional excitable media is investigated. Sufficiently strong rapid forcing converts expanding scroll rings into the collapsing ones and suppresses the Winfree turbulence caused by the negative tension of wave filaments. Slow strong forcing has an opposite effect, leading to expansion of scroll rings and induction of the turbulence. These effects are explained in the framework of the phenomenological kinematic theory of scroll waves.

Análisis de la caricatura política desde la perspectiva de las teorías funcionalistas de los media. Una discusión en torno a los mecanismos de control social o ciudadano

De acuerdo con las funciones de la caricatura política como medio de comunicación se busca identificar cómo ésta logra ser un actor fundamental en el sistema político, logrando de esta manera poder explicar en qué medida la caricatura política logra actuar como control social o ciudadano. Para lograr esta explicación, primero se hace una descripción del control social, mostrando la relevancia de la información en la construcción del control, logrando articularlo con las funciones mediáticas, produciendo de este modo un concepto unificado de información. Gracias a esto se logra demostrar la importancia de la caricatura política como un regulador del sistema político y debido a sus características, las fortalezas de la caricatura frente a otros medios de comunicación.
