European Newspapers’ Digital Transition: New Products and New Audiences

The adaptation of traditional newspapers to new digital media and its interface, far from being a mere technical transformation, has contributed to a gradual change in the media themselves and their audiences. With a sample including the top general information pay newspaper in each of the 28 countries of the European Union, this research has carried out an analysis using 17 indicators divided in 4 categories. The aim is to identify the transformations that the implementation of digital media have brought to the top European newspapers. In general terms, the results show that most dailies have managed to keep their leadership also in online environment. Moreover, an emerging group of global media is growing up, based in preexisting national media. Digital and mobile media have contributed to the appearance of new consumption habits as well, where users read more superficially and sporadically. The audience uses several formats at a time, and digital devices already bring the biggest amount of users to many media. The Internet-created new information windows –search engines, social networks, etc. –are also contributing to the change in professional work routines.

White spot syndrome virus (WSSV) transmission risk through infected cooked shrimp products assessed by polymerase chain reaction (PCR) and bio-inoculation studies

The aim of the study was to evaluate the resistance of white spot syndrome virus (WSSV) in shrimps (Penaeus monodon) to the process of cooking. The cooking was carried out at 1000C six different durations 5, 10, 15, 20, 25 and 30 min. The presence of WSSV was tested by single step and nested polymerase chain reaction (PCR). In the single step PCR, the primers 1s5 & 1a16 and IK1 & IK2 were used. While in the nested PCR, primers IK1 &IK2 – IK3 & IK4 were used for the detection of WSSV. WSSV was detected in the single step PCR with the primers 1s5 and 1a16 and the nested PCR with the primers IK1 and IK2 – IK3 & IK4 from the cooked shrimp samples. The cooked shrimps, which gave positive results for WSSV by PCR, were further confirmed for the viability of WSSV by conducting the bio-inoculation studies. Mortality (100%) was observed within 123 h of intra-muscular post injection (P.I) into the live healthy WSSV-free shrimps (P. monodon). These results show that the WSSV survive the cooking process and even infected cooked shrimp products may pose a transmission risk for WSSV to the native shrimp farming systems.

Effect of crude oil and some petroleum products on Clarias Gariepinus fingerlings (Catfish: Claridae)

Ninety (90) hatchery bred fingerlings of Clarias gariepinus (mean weight: 0.96 ± 0.1g) were randomly placed in 15 plastic baths (25 litres each) at the Research laboratory and were exposed to different concentrations of oil products to determine their effects on the fish, to facilitate inferential deductions that will enhance effective aquatic environmental management. Three (3) replicate basins of 5 experimental treatments (crude oil, petrol oil, kerosene oil, engine oil and control) were used at a concentration of 1.25ml. L-1. The control experiment was devoid of oil treatment. Six (6) fingerlings were placed in each replicate basin, flooded with 20 litres of clean tap water and fed with nutrafin cichilid food, 2 times daily at 3% body weight. The results showed that the feeding behaviour and swimming performances of fish were reduced after 24 hours of the addition of the various oil pollutants. Mortality of fingerlings in the oiled basins increased as the hours of exposure increased (i.e. 24, 48, 72 and 96 hours). Recovery was not immediate in the treated basin while surviving fingerlings in the control basins grew up to post-fingerlings after 90 days (3 months). There were significant differences (P<0.01 and P<0.05) in the effect of crude oil and the petroleum products on the mortality rate of C. gariepinus when exposed to oil pollutants at 1.25ml. L-1 concentration

Camino a la jubilación: alquiler versus compra de vivienda

Las previsiones del número de personas mayores en España para el año 2050 se han disparado. Un aumento de la población mayor que supondrá grandes dificultades para un sistema público de pensiones cuya viabilidad está en duda. España es un país en el que la cultura del ahorro a través de la vivienda en propiedad está muy arraigada. Sin embargo, en la actualidad existe un auge de las personas que optan por el alquiler como forma de residencia. Por ello, durante este trabajo se analiza la vida de una persona que optará bien por la compra de una vivienda o bien por el alquiler de una vivienda para complementar su futura pensión pública. Mediante la compra de vivienda, y una vez amortizado el préstamo hipotecario que deberá soportar, se le presentaran los productos denominados vivienda pensión e hipoteca inversa para financiar las posibles necesidades que puedan surgir en su jubilación. Por otro lado, el arrendatario optara por un producto de ahorro a largo plazo, cuya rentabilidad variara a lo largo del tiempo en función de su aversión al riesgo, de manera que llegado el momento de la jubilación disponga de un capital.

Representação da Qualidade de Vida na Revista Vida Simples

É nas grandes cidades que a temática da qualidade de vida vem sendo posta em voga na última década, especialmente, como cita Freitas (1996, p.4), pela busca por melhores condições de vida, face à gama de sintomas de falência do projeto moderno de cidade tentado desde o século XIX; a violência, a poluição, o stress angustiam o homem e o obrigam a tribalizar, inclusive sob o aspecto espacial, seu quotidiano. Para entender de que maneira os meios de comunicação abordam este tema, especialmente o veículo revista, foi traçado um estudo sobre a representação da qualidade de vida na revista Vida Simples, da editora Abril, produzida nas matérias da seção Comer. Tal publicação foi eleita pela pluralidade de informações que adentram as pautas sobre saúde, emoções, bem-estar, afetividade, sentidos, sociabilidade e destacam o caráter simbólico de uma vida harmoniosa, afetando o comportamento dos citadinos no contexto da existência turbulenta das metrópoles. Para compor o referencial foram considerados teóricos do campo da Representação Social, Comunicação e Consumo. Além de oferecerem subsídios para refletir sobre os produtos da Indústria Cultural, o conjunto de representações que constroem o imaginário urbano e o consumo de conceitos e produtos, as ideias apresentadas no universo da qualidade de vida também colaboram para compor as categorias elaboradas para a análise de conteúdo das matérias selecionadas. Para entender de que maneira a revista aborda esse tipo de consumo e também quais são as representações produzidas sobre a qualidade de vida, foram analisadas 6 edições da Revista Vida Simples, de janeiro a junho de 2010

Marketing Ecológico: análisis teórico, estudio empírico a consumidores y análisis del diferencial de precios

ESPAÑOL:Este Trabajo de Fin de Grado se centra en el estudio, tanto teórico como empírico, de cuestiones relacionadas esencialmente con el conocimiento, consumo y marketing de productos ecológicos. Comienza con el marco teórico basado en la revisión bibliográfica de los trabajos publicados sobre la materia que se adjuntan en la bibliografía relacionada al final. Posteriormente, se presentan los resultados de una encuesta que realizamos a 63 personas que realizan habitualmente la compra de su hogar y que tuvo como objeto descubrir el grado de conocimiento que tienen sobre los productos eco, el consumo particular que hacen de los mismos y las razones que les impulsan a su consumo o que frenan el mismo, diferenciando el caso de los productos ecológicos de alimentación de los demás productos ecológicos. Se completa el trabajo con la presentación de un análisis empírico del diferencial de precios de los productos ecológicos frente a los de los productos convencionales de similares características. Para ello nos centramos exclusivamente en los productos (ecológicos y no ecológicos) vendidos en la plataforma de venta on line por una gran empresa española de distribución de base alimentaria, concretamente, Eroski.

Effects of oxygen partial pressure on packing density and laser damage threshold of TiO2 thin films

TiO2 films are deposited by electron beam evaporation as a function of oxygen partial pressure. The packing density, refractive index, and extinction coefficient all decrease with the increase of pressure, which also induces the change of the film's microstructure, such as the increase of voids and H2O concentration in the film. The laser-induced damage threshold (LIDT) of the film increases monotonically with the rise of pressure in this experiment. The porous structure and low nonstoichiometric defects absorption contribute to the film's high LIDT. The films prepared at the lowest and the highest pressure show nonstoichiometric and surface-defects-induced damage features, respectively.(C) 2007 American Institute of Physics.
