Porquê estudar o jornalismo?

As II Jornadas Internacionais de Jornalismo da Universidade Fernando Pessoa, organizadas pelo Centro de Estudos da Comunicação da instituição, pretenderam ser um espaço privilegiado para os professores e investigadores de instituições de ensino superior apresentarem e discutirem ideias e resultados de pesquisas no campo dos Estudos Jornalísticos, bem como para lançarem as bases de projectos comuns. Foi ainda objectivo dos organizadores que as Jornadas constituíssem uma plataforma para os estudantes de graduação e pós-graduação em Jornalismo tomarem contacto com a pesquisa avançada neste campo e, eventualmente, apresentarem trabalhos resultantes da sua investigação, a título individual ou em conjunto com os seus professores. Fomentou-se, também, a adesão de jornalistas, para que a sua experiência como protagonistas do processo jornalístico enriquecesse as Jornadas e permitisse uma interacção rica entre eles, os estudantes que aspiram a tornar-se jornalistas e os investigadores que se dedicam a estudar o Jornalismo, pois é tempo de a Academia e os profissionais deixarem de andar de costas voltadas. Para isso, é preciso atrair os jornalistas à Universidade, tal como é preciso franquear o acesso dos órgãos jornalísticos aos investigadores.

Influencia de la humedad del grano y la velocidad de trabajo sobre las pérdidas de cosecha en soja

Argentina es considerada como el país de mayor competitividad para producir soja en el mundo, ya que ha logrado obtener el mayor rendimiento promedio de soja de primera y el menor costo de producción. Para esta campaña se espera una producción récord de cerca de 50 millones de toneladas, para la cual en el país hay alrededor de 25.000 cosechadoras, número insuficiente para una recolección eficiente. Normalmente la cosecha se realiza en otoño momento en el cual las inclemencias del tiempo pueden producir retardos en la recolección, lo que sumado al hecho de la simultaneidad de cultivos para cosechar, provoca que los operarios de las cosechadores aumenten las velocidades de trabajo, tanto de la máquina como del cilindro trillador lo que provoca incrementos de las pérdidas y del daño mecánico del grano, sobre todo en soja, que tiene un momento óptimo de recolección muy acotado. En el presente trabajo se evaluó el desempeño de una cosechadora convencional en la cosecha de un cultivo de soja con dos humedades de grano y tres velocidades de avance de la máquina. Se mensuraron las pérdidas por plataforma, por cola y de cosecha, contrastándose los resultados mediante ANOVA y Test de Tukey (p menor a 0,05). Los resultados obtenidos mostraron pérdidas con diferencias significativas entre las velocidades y entre las humedades, ensayadas, como así también entre las pérdidas por cola respecto a las de plataforma; pero no se encontró interacción entre las velocidades y las diferentes humedades. Se estima que los resultados obtenidos podrán aportar a los productores algunas herramientas más, a la hora de efectuar la cosecha de soja, especialmente cuando ésta alcance humedades de comercialización o aún menores, con el objetivo de minimizar las pérdidas ocasionadas por la máquina.

Ecuaciones lineales con una incógnita

Este capítulo presenta el diseño, implementación y evaluación de una unidad didáctica sobre ecuaciones lineales con una incógnita. Diseñamos e implementamos la unidad didáctica objeto de este trabajo teniendo en cuenta las dificultades que presentan los estudiantes en la traducción al lenguaje algebraico, el planteamiento y solución de ecuaciones lineales de primer grado y la solución de problemas con ecuaciones lineales de primer grado. La interpretación de frases de la cotidianidad que deben ser traducidas a un lenguaje formal para construir expresiones algebraicas y con ellas generar ecuaciones crean una barrera para la utilización real del álgebra. Para alcanzar un aprendizaje significativo de los procesos algebraicos es necesario dotar las actividades de significado dentro del contexto del joven y así tener un aprendizaje concreto que posteriormente sirva de plataforma para el uso de la ecuación como herramienta fundamental en la aplicación del algebra en contextos reales.

Geometría analítica plana con geogebra

En este artículo se describe una experiencia desarrollada con alumnos de 1º de bachillerato de la modalidad de Ciencias y Tecnología (16 y 17 años) durante el curso escolar 2009/10, con el objetivo de trabajar los problemas métricos de geometría analítica plana, utilizando las nuevas tecnologías. En concreto se utiliza el programa Geogebra, la plataforma digital de formación Moodle y la pizarra digital interactiva (PDI). El programa Geogebra nos ayuda a estudiar gráficamente los problemas, además de comprobar sus resultados analíticos; con la plataforma Moodle se consigue que el alumnado dedique de forma efectiva más tiempo al estudio mientras está fuera del centro y la PDI les permite visualizar la resolución gráfica e interactuar en su corrección. En el artículo se describe el contexto en el que se desarrolla la experiencia, el alumnado a quién va dirigida, los objetivos que se pretenden, un ejemplo de problema desarrollado en el aula y otro por los alumnos en sus casas. Finalmente se valora la experiencia y los resultados.

Analysis of the footprint in school age of 8-10 years old

Biomechanical problems in children, is an important subject currently, existing controversy in different areas, for example, the majority of children have a flattened footprint, or the hypermobility joint is linked to a musculoskeletal pain. The objective of the study was to determine what kind of footprint is most frequent in school-age children (8-10 years) in the area of Plasencia. This was taken as a sign 50 children, of whom 28 were males and 22 females. All the subjects in the study underwent an assessment of footprint planted in static as well as an exploration of different parameters through inspection in a standing position (formula digital, rearfoot). The results show that excavated footprint is present in a 72% cases of the population, 16% was belonging to an excavated footprint in which we find a higher percentage of weight related.For the digital formula we find that the most common is the Egyptian foot by 40% of the cases and that the prevalence in the rearfoot, is a normal hindfoot. In relation with the hypermobility joint, we check that it is more common in girls and that none of them presents an association to musculoskeletal pain. As a future line we could establish a more comprehensive study with new techniques and valuingchild’s statics and dynamics, to have a more accurate study of the different variables in the sample population studied.

A quantitative and qualitative study of audiovisual materials of Extremadura bands was done to find out which processes are most suitable to increase the number of viewers for videos.

Discovering keys to explain social policies within the social and democratic rule-of-law sate

There is a collective worldview on social policies that is expressed and understood by university professionals. However, it takes students time to construct this knowledge. Here, we provide fundamental ideas and a dynamic to facilitate learning of social policies. The preparation of a brief dictionary of significant terms is to be constructed as a group, alongside the maieutic work to be carried out by the teacher. The goal is to discover keys to understand the meaning of social policies and the underlying values that sustain a social and democratic rule-of-law state such as the one proposed in the Spanish Constitution of 1978. Attention is focused on the structure of the mixed welfare state. This is an integral proposal and comprises three dimensions. First, it considers the state and its possible welfare agents: business, market, the Church and civil society. The attitudes with which universal and inclusive social action is promoted, breaking radically with the aid-based meaning contained in other systems, are then addressed. Finally, we examine human dignity as a principle and aim of intervention, a basis for understanding other concepts such as human, social, labour and political rights. It is to be hoped that these pages prove useful for both teaching staff and students.

Upin & Ipin: Promoting malaysian culture values through animation

Malaysian children lately have been exposed or influenced heavily by digital media entertainment. The rise of such entertainment tends to drive them away from understanding and appreciating the values of Malaysian culture. Upin and Ipin animation has successfully promoted Malaysian folklore culture and has significantly portrayed the art of Malaysian values including Islamic values by providing the platform for harmonious relationship among different societies or groups or religious backgrounds. The focus of this research is to look into the usage of Malaysian culture iconic visual styles such as backgrounds, lifestyles, character archetypes and narrative (storytelling). Therefore, we hope that this research will benefit the younger generation by highlighting the meaning and importance of implicit Malaysian culture.

La ruptura de una economía moral y las deslegitimación de las deudas hipotecarias

In Spain, during the recent housing bubble, purchasing a home seemed the most advantageous strategy to access housing, and there was a wide social consensus about the unavoidability of mortgage indebtedness. However, such consensus has been challenged by the financial and real-estate crisis. The victims of home repossessions have been affected by the transgression of several principles, such as the fair compensation for effort and sacrifice, the prioritisation of basic needs over financial commitments, the possibility of a second chance for over-indebted people, or the State's responsibility to guarantee its citizens' livelihood. Such principles may be understood as part of a moral economy, and their transgression has resulted in the emergence of a social movement, the Plataforma de Afectados por la Hipoteca (PAH), that is questioning the legitimacy of mortgage debts. The article reflects on the extent to which the perception of over-indebtedness and evictions as unfair situations can have an effect on the reproduction of the political-economic system, insofar the latter is perceived as able or unable to repair injustice.

A methodological framework for studying policy coherence for development

The purpose of this article is to develop a methodological framework for analyzing Policy Coherence for Development (PCD). With this goal, we analyze different views of PCD in order to establish a comprehensive approach of Coherence adapted to globalization process. In this context, the article proposes a methodological framework based on four dimensions of analysis in CPD. In each dimen-sion, we set the areas and actors to investigate and we put forward research questions that could be use as a guide for a comprehensive approach to study PCD.
