Facebook e Twitter Todateen: fortalecimento da identidade de uma marca já consolidada na mídia impressa

The society went through several transformations, especially technological. With the democratization of the Internet and social media, forms of relationships have turned up in between brand and consumer. Thus, marketing availed human characteristics in order to meet and interact with the consumer. So many print magazines have created profiles on Facebook and Twitter with the primary intent of disseminating original content and become a channel of dialogue with the reader. This research aims to reflect on the role of journalist as brand managers and social media acting as a magazine brand strength ening strategy. The research will examine the Todateen magazine, teen magazine focused on class C, and their profiles from Facebook and Twitter as a way to expand the relationship with the reader, to humanize the brand and strengthen the identity of the magazine. The methodologies used are exploratory and analytical to, first, discuss the issues: magazine journalism, media convergence, web journalism, social media, corporate communications, branding and marketing, and then analyze the Todateen case, describing the print media, the website, Twitter and Facebook

Desafios da comunicação interna em departamentos de jornalismo

This paper focuses on the importance of internal communication within the journalism departments of regional Brazilian open television networks. This research shows that these professionals recognized that communication can improve relationship among staff and journalistic performance. However, just one of the companies researched invests in internal communication management. The present study also reveals many challenges which influence internal communication, relationship, and the journalistic work in these companies, such as: lean teams, interferences from other areas in the journalistic writing, lack of formal network of communication, competition among members of the team, the journalist's professional profile, need for shared leadership and internal communication policies and information management.

An Analysis of Next Generation Access Networks Deployment in rural areas

Next generation access networks (NGAN) will support a renewed electronic communication market where main opportunities lie in the provision of ubiquitous broadband connectivity, applications and content. From their deployment it is expected a wealth of innovations. Within this framework, the project reviews the variety of NGAN deployment options available for rural environments, derives a simple method for approximate cost calculations, and then discusses and compares the results obtained. Data for Spain are used for practical calculations, but the model is applicable with minor modifications to most of the rural areas of European countries. The final part of the paper is devoted to review the techno-economic implications of a network deployment in a rural environment as well as the adequacy and possible developments of the regulatory framework involved

Modelos Estadísticos Dinámicos para Análisis de Evolución de Tasas de Accidentes: Metodología y Herramientas Computacionales

Los accidentes del tráfico son un fenómeno social muy relevantes y una de las principales causas de mortalidad en los países desarrollados. Para entender este fenómeno complejo se aplican modelos econométricos sofisticados tanto en la literatura académica como por las administraciones públicas. Esta tesis está dedicada al análisis de modelos macroscópicos para los accidentes del tráfico en España. El objetivo de esta tesis se puede dividir en dos bloques: a. Obtener una mejor comprensión del fenómeno de accidentes de trafico mediante la aplicación y comparación de dos modelos macroscópicos utilizados frecuentemente en este área: DRAG y UCM, con la aplicación a los accidentes con implicación de furgonetas en España durante el período 2000-2009. Los análisis se llevaron a cabo con enfoque frecuencista y mediante los programas TRIO, SAS y TRAMO/SEATS. b. La aplicación de modelos y la selección de las variables más relevantes, son temas actuales de investigación y en esta tesis se ha desarrollado y aplicado una metodología que pretende mejorar, mediante herramientas teóricas y prácticas, el entendimiento de selección y comparación de los modelos macroscópicos. Se han desarrollado metodologías tanto para selección como para comparación de modelos. La metodología de selección de modelos se ha aplicado a los accidentes mortales ocurridos en la red viaria en el período 2000-2011, y la propuesta metodológica de comparación de modelos macroscópicos se ha aplicado a la frecuencia y la severidad de los accidentes con implicación de furgonetas en el período 2000-2009. Como resultado de los desarrollos anteriores se resaltan las siguientes contribuciones: a. Profundización de los modelos a través de interpretación de las variables respuesta y poder de predicción de los modelos. El conocimiento sobre el comportamiento de los accidentes con implicación de furgonetas se ha ampliado en este proceso. bl. Desarrollo de una metodología para selección de variables relevantes para la explicación de la ocurrencia de accidentes de tráfico. Teniendo en cuenta los resultados de a) la propuesta metodológica se basa en los modelos DRAG, cuyos parámetros se han estimado con enfoque bayesiano y se han aplicado a los datos de accidentes mortales entre los años 2000-2011 en España. Esta metodología novedosa y original se ha comparado con modelos de regresión dinámica (DR), que son los modelos más comunes para el trabajo con procesos estocásticos. Los resultados son comparables, y con la nueva propuesta se realiza una aportación metodológica que optimiza el proceso de selección de modelos, con escaso coste computacional. b2. En la tesis se ha diseñado una metodología de comparación teórica entre los modelos competidores mediante la aplicación conjunta de simulación Monte Cario, diseño de experimentos y análisis de la varianza ANOVA. Los modelos competidores tienen diferentes estructuras, que afectan a la estimación de efectos de las variables explicativas. Teniendo en cuenta el estudio desarrollado en bl) este desarrollo tiene el propósito de determinar como interpretar la componente de tendencia estocástica que un modelo UCM modela explícitamente, a través de un modelo DRAG, que no tiene un método específico para modelar este elemento. Los resultados de este estudio son importantes para ver si la serie necesita ser diferenciada antes de modelar. b3. Se han desarrollado nuevos algoritmos para realizar los ejercicios metodológicos, implementados en diferentes programas como R, WinBUGS, y MATLAB. El cumplimiento de los objetivos de la tesis a través de los desarrollos antes enunciados se remarcan en las siguientes conclusiones: 1. El fenómeno de accidentes del tráfico se ha analizado mediante dos modelos macroscópicos. Los efectos de los factores de influencia son diferentes dependiendo de la metodología aplicada. Los resultados de predicción son similares aunque con ligera superioridad de la metodología DRAG. 2. La metodología para selección de variables y modelos proporciona resultados prácticos en cuanto a la explicación de los accidentes de tráfico. La predicción y la interpretación también se han mejorado mediante esta nueva metodología. 3. Se ha implementado una metodología para profundizar en el conocimiento de la relación entre las estimaciones de los efectos de dos modelos competidores como DRAG y UCM. Un aspecto muy importante en este tema es la interpretación de la tendencia mediante dos modelos diferentes de la que se ha obtenido información muy útil para los investigadores en el campo del modelado. Los resultados han proporcionado una ampliación satisfactoria del conocimiento en torno al proceso de modelado y comprensión de los accidentes con implicación de furgonetas y accidentes mortales totales en España. ABSTRACT Road accidents are a very relevant social phenomenon and one of the main causes of death in industrialized countries. Sophisticated econometric models are applied in academic work and by the administrations for a better understanding of this very complex phenomenon. This thesis is thus devoted to the analysis of macro models for road accidents with application to the Spanish case. The objectives of the thesis may be divided in two blocks: a. To achieve a better understanding of the road accident phenomenon by means of the application and comparison of two of the most frequently used macro modelings: DRAG (demand for road use, accidents and their gravity) and UCM (unobserved components model); the application was made to van involved accident data in Spain in the period 2000-2009. The analysis has been carried out within the frequentist framework and using available state of the art software, TRIO, SAS and TRAMO/SEATS. b. Concern on the application of the models and on the relevant input variables to be included in the model has driven the research to try to improve, by theoretical and practical means, the understanding on methodological choice and model selection procedures. The theoretical developments have been applied to fatal accidents during the period 2000-2011 and van-involved road accidents in 2000-2009. This has resulted in the following contributions: a. Insight on the models has been gained through interpretation of the effect of the input variables on the response and prediction accuracy of both models. The behavior of van-involved road accidents has been explained during this process. b1. Development of an input variable selection procedure, which is crucial for an efficient choice of the inputs. Following the results of a) the procedure uses the DRAG-like model. The estimation is carried out within the Bayesian framework. The procedure has been applied for the total road accident data in Spain in the period 2000-2011. The results of the model selection procedure are compared and validated through a dynamic regression model given that the original data has a stochastic trend. b2. A methodology for theoretical comparison between the two models through Monte Carlo simulation, computer experiment design and ANOVA. The models have a different structure and this affects the estimation of the effects of the input variables. The comparison is thus carried out in terms of the effect of the input variables on the response, which is in general different, and should be related. Considering the results of the study carried out in b1) this study tries to find out how a stochastic time trend will be captured in DRAG model, since there is no specific trend component in DRAG. Given the results of b1) the findings of this study are crucial in order to see if the estimation of data with stochastic component through DRAG will be valid or whether the data need a certain adjustment (typically differencing) prior to the estimation. The model comparison methodology was applied to the UCM and DRAG models, considering that, as mentioned above, the UCM has a specific trend term while DRAG does not. b3. New algorithms were developed for carrying out the methodological exercises. For this purpose different softwares, R, WinBUGs and MATLAB were used. These objectives and contributions have been resulted in the following findings: 1. The road accident phenomenon has been analyzed by means of two macro models: The effects of the influential input variables may be estimated through the models, but it has been observed that the estimates vary from one model to the other, although prediction accuracy is similar, with a slight superiority of the DRAG methodology. 2. The variable selection methodology provides very practical results, as far as the explanation of road accidents is concerned. Prediction accuracy and interpretability have been improved by means of a more efficient input variable and model selection procedure. 3. Insight has been gained on the relationship between the estimates of the effects using the two models. A very relevant issue here is the role of trend in both models, relevant recommendations for the analyst have resulted from here. The results have provided a very satisfactory insight into both modeling aspects and the understanding of both van-involved and total fatal accidents behavior in Spain.

Metodología para deducir relaciones de linaje en el catastro de España.

En España, los datos catastrales de acceso público, obtenidos a través de la Sede Electrónica del Catastro (SEC), no incluyen información sobre la genealogía o las relaciones de linaje existente entre las parcelas, de forma que la gestión de la información histórica es muy limitada. Este artículo presenta un método para obtener las relaciones de linaje más frecuentes entre las parcelas (agregación y segregación) y propone un prototipo de estructura relacional para el almacenamiento y la gestión histórica de los datos catastrales de acceso público. El proceso de análisis para deducir el linaje se basa en superposiciones espacio-temporales junto con secuencias de sentencias SQL. El método proporciona un 70% de relaciones de agregación y segregación correctas; el resto presentan errores debidos, en general, a anomalías presentes en los propios datos catastrales. ABSTRACT Public cadastral data in Spain, available through the Electronic Office of Cadastre, do not include any information on the genealogy or lineage relationship among the parcels, so the management of historical information becomes very limit ed. This paper presents a method for obtaining the most common lineage relationships between plots (aggregation and segregation) and proposes a relational structure prototype for the storage and historic management of public cadastral data. The analysis process to deduce the lineage is based on spatio-temporal overlaps coupled with SQL statements sequences. This method provides a 70% of correct aggregation and segregation relationships; the wrong cases are mainly caused by errors existing in the cadastral data themselves.

El análisis de los efectos de la escuela sobre el rendimiento académico en matemáticas: un análisis multinivel con datos de PISA 2003

Esta investigación, enmarcada dentro del movimiento sobre Eficacia de la Escuela, realiza una explotación parcial de los datos PISA 2003, para el territorio español, obtenidos en la investigación llevada a cabo por la OCDE. El alumnado español que ha participado en el estudio PISA, supone un total de 10.791 estudiantes de 383 centros de Educación Secundaría pertenecientes a varias Comunidades Autónomas. Las variables predictoras que forman parte de la investigación se obtienen de alumno y del centro. La variable de respuesta, desde un enfoque criterial, establece información sobre el nivel de competencias alcanzado por el alumno en matemáticas. Los resultados del análisis multinivel proporcionan diferentes modelos que tratan de explicar la variabilidad observada entre los centros a través de la incorporación de sus variables. El modelo resultante reconoce que las variables de centro: titularidad, porcentaje de alumnas, fomento de actividades matemáticas y compromiso y moral del alumnado se relacionan con el rendimiento en matemáticas.

Audiencia tradicional frente a audiencia social: un análisis comparativo en el prime-time televisivo

La interacción de redes sociales y productos televisivos ha dado pie al nacimiento de la televisión social en la que el espectador participa activamente en el desarrollo de los espacios. Este fenómeno emergente está siendo objeto de múltiples investigaciones en el campo de las audiencias por las posibilidades y el potencial que supone para el medio a la hora de conocer e interactuar con los espectadores. El objetivo de este trabajo es realizar una comparación entre la audiencia real y la audiencia social (o impacto social) de los programas emitidos en prime-time durante varias semanas de los meses de abril y mayo de 2013. Esta investigación se centra en Twitter por ser la red social que concentra gran parte de los debates sobre televisión (Gallego, 2013). Para ello se plantean las siguientes hipótesis de partida: 1- No existe paralelismo entre los cinco programas más vistos en televisión con aquellos que se sitúan entre los cinco con mayor audiencia social del mismo día. 2- El éxito de un programa en audiencia social no depende exclusivamente de su formato. Para alcanzar los objetivos de la investigación se estudian los datos de audiencia real procedentes de Kantar Media, así como los de impacto social facilitados Tuitele y Global-In-Media.

The ethics pyramid: Making ethics unavoidable in the public relations process

To move from the realm of good intent to verifiable practice, ethics needs to be approached in the same way as any other desired outcome of the public relations process: that is, operationalized and evaluated at each stage of a public relations campaign. A pyramid model—the "ethics pyramid" —is useful for incorporating ethical reflection and evaluation processes into the standard structure of a typical public relations plan. Practitioners can use it to integrate and manage ethical intent, means, and ends, by setting ethics objectives, considering the ethics of each campaign tactic, and reporting whether ethical outcomes have been attained.

Essays on openness, economic integration, and *growth

This dissertation examines the relationship between the degree of openness to international trade and the level of growth experienced by a country. More precisely, it explores how trade liberalization and economic integration can lead to specialization in production, affect national levels of welfare, productivity, and competition and at the same time reinforce deflationary efforts. A large part of this investigation is carried out using industry-level data from Spain. ^

The consumer before the infoxication in the press discourse

In the media current context, the user is exposed every day to an informative saturation without precedents. The variety of the media by means of that it receives information, together with the revolution to all the levels that has supposed the Internet integration, it does that the consumer is bombarded literally by multitude of messages. But this bombardment does not imply an informative quality, but it can suppose an imbalance between the number of information and the quality of the same ones, avoiding so the user know the reality with veracity and depth. This article analyzes exhaustively the phenomenon of this overexposure named infoxication, the true dangers that it encloses, the possible solutions and how it affects the user and the Journalism in the production of written and audiovisual products through different mass media.

A Multimedia Video Player Based of FFmpeg

With the rapid development of Internet technologies, video and audio processing are among the most important parts due to the constant requirements of high quality media contents. Along with the improvement of network environment and the hardware equipment, this demand is becoming more and more imperious, people prefer high quality videos and audios as well as the net streaming media resources. FFmpeg is a set of open source program about the A/V decoding. Many commercial players use FFmpeg as their displaying cores. This paper designed a simple and easy-to-use video player based on FFmpeg. The first part is about the basic theories and related knowledge of video displaying, including some concepts like data formats, streaming media data, video coding and decoding. In a word, the realization of the video player depend on the a set of video decoding process. The general idea about the process is to get the video packets from the Internet, to read the related protocols and de-encapsulate the protocols, to de-encapsulate the packaging data and to get encoded formats data, to decode them to pixel data that can be displayed directly through graphics cards. During the coding and decoding process, there could be different degrees of data losing, which is called lossy compression, but it usually does not influence the quality of user experiences. The second part is about the principle of the FFmpeg decoding process, that is one of the key point of the paper. In this project, FFmpeg is used for the main decoding task, by call some main functions and structures from FFmpeg class libraries, packaging video formats could be transfer to pixel data, after getting the pixel data, SDL is used for the displaying process. The third part is about the SDL displaying flow. Similarly, it would invoke some important displaying functions from SDL class libraries to realize the function, though SDL is able to do not only displaying task, but also many other game playing process. After that, a independent video displayer is completed, it is provided with all the key function of a player. The fourth part make a simple users interface for the player based on the MFC program, it enable the player could be used by most people. At last, in consideration of the mobile Internet’s blossom, people nowadays can hardly ever drop their mobile phones, there is a brief introduction about how to transplant the video player to Android platform which is one of the most used mobile systems.
