Researchs about consumer behavior show influences coming from a lot of fonts. Among them culture, social class, personal influence, family and consumer situation. Personal influence it’s the font object of this research. Personal influence can define what a consumer will buy or will not buy, especially with closer friends. Normally people got the information and transmit to him group, him family, making some difference in the opinion of this people. Ten years ago we were i………..by a dozen of friends. In these days, we have more facility to communicate and more facility to receiver information trough internet. Our personal influence extended from our closest friend to the world wide web group. That’s why company’s must to know what the consumer is speaking on internet

The paper studies the mobilization occurred in June 2013 in Brazil, initially under the banner of the Movement Free Pass, but without the existence of a lead, but multiple voices that alternate in search of social and economic change. The object of study is the communication made through social networks and their realization, or realization, the streets of major cities. The rallies demonstrate the power of communications media and a new phenomenon of talk, the use of social networks, now as uniting factor and not just a showcase of everyday life. The internet has become a new means of communication easy and free access, in addition to its fast dissipation data. Thus, the youth was used such technology to an uprising in the pursuit of social improvement of the cities where marches happened. Such a move still without an academic and social needs to be discussed so that, in addition to understood, can expand contributions to society, helping it in its claims. Was chosen as the site for the #causabrasil study and understanding of issues in which the public expresses dissatisfaction. The site performs an analysis with the combination of hastags a list of pre-registered and a list of terms used by different users of Facebook, Twitter, Instagram, Youtube and Google, through monitoring tool Seekr, and an infographic presents the main political demands of the population.

La popularización de los medios digitales y los recursos de comunicación difunde las narrativas no lineales y agrava la crisis de la enseñanza en el aula, con la expansión de diferentes modelos presenciales virtuales de la educación (PVE). Es evidente la demasificación de los nuevos medios, en un contexto que agudiza la percepción individual y social de los individuos, que son atraídos por el enorme flujo global de mensajes informativos (BRIGGS; BURKE, 2006). La transición de los métodos de enseñanza en el aula para modelar la educación virtual e interactiva ganó un nuevo formato en la educación pública en São Paulo en 2012, con el lanzamiento de cursos electivos de enseñanza de Inglés y Español para estudiantes de la secundaria, con la mediación de el PC y con el contenido producido por la Escuela Virtual de Programas Educativos del Estado de São Paulo - Evesp. Aún continua presencia en los salones de las grandes clases del sistema escolar, la falta de materiales de enseñanza y aprendizaje adecuados en las clases impartidas por los profesores cuyos repertorios están alejados de la vida cotidiana de los estudiantes. En este contexto, se comprueban las actuaciones de aprendizaje cualitativos más bien negativos de las cuatro habilidades comunicativas: escuchar, hablar, leer y escribir (CAMERON, 2001). La investigación que llevamos a cabo es analizar las experiencias de enseñanza de Inglés y Español en la plataforma computarizada Evesp y de la clase de Inglés y Español de los Centros para el Curso de idiomas (CELS), para la escuela secundaria, y el piloto Early Bird, de enseñanza y el aprendizaje de Inglés de la escuela primaria, todos bajo la Junta de Educación de Bauru (SP).

This paper presents a hybrid way mixing time and frequency domain for transmission lines modelling. The proposed methodology handles steady fundamental signal mixed with fast and slow transients, including impulsive and oscillatory behaviour. A transmission line model is developed based on lumped elements representation and state-space techniques. The proposed methodology represents an easy and practical procedure to model a three-phase transmission line directly in time domain, without the explicit use of inverse transforms. The proposed methodology takes into account the frequency-dependent parameters of the line, considering the soil and skin effects. In order to include this effect in the state matrices, a fitting method is applied. Furthermore the accuracy of proposed the developed model is verified, in frequency domain, by a simple methodology based on line distributed parameters and transfer function related to the input/output signals of the lumped parameters representation. In addition, this article proposes the use of a fast and robust analytic integration procedure to solve the state equations, enabling transient and steady-state simulations. The results are compared with those obtained by the commercial software Microtran (EMTP), taking into account a three-phase transmission line, typical in the Brazilian transmission system.

This article shows a transmission line model for simulation of fast and slow transients, applied to symmetrical or asymmetrical configurations. A transmission line model is developed based on lumped elements representation and state-space techniques. The proposed methodology represents a practical procedure to model three-phase transmission lines directly in time domain, without the explicit or implicit use of inverse transforms. In three-phase representation, analysis modal techniques are applied to decouple the phases in their respective propagation modes, using a correction procedure to set a real and constant matrix for untransposed lines with or without vertical symmetry plane. The proposed methodology takes into account the frequency-dependent parameters of the line and in order to include this effect in the state matrices, a fitting procedure is applied. To verify the accuracy of the proposed state-space model in frequency domain, a simple methodology is described based on line distributed parameters and transfer function associated with input/output signals of the lumped parameters representation. In addition, this article proposes the use of a fast and robust integration procedure to solve the state equations, enabling transient and steady-state simulations. The results obtained by the proposed methodology are compared with several established transmission line models in EMTP, taking into account an asymmetrical three-phase transmission line. The principal contribution of the proposed methodology is to handle a steady fundamental signal mixed with fast and slow transients, including impulsive and oscillatory behavior, by a practical procedure applied directly in time domain for symmetrical or asymmetrical representations.
