This article advances the theoretical integration between securitization theory and the framing approach, resulting in a set of criteria hereby called security framing. It seeks to make a twofold contribution: to sharpen the study of the ideational elements that underlie the construction of threats, and to advance towards a greater assessment of the audience's preferences. The case study under examination is the 2011 military intervention of the countries of the Gulf Cooperation Council in Bahrain. The security framing of this case will help illuminate the dynamics at play in one of the most important recent events in Gulf politics.

For modern consumer cameras often approximate calibration data is available, making applications such as 3D reconstruction or photo registration easier as compared to the pure uncalibrated setting. In this paper we address the setting with calibrateduncalibrated image pairs: for one image intrinsic parameters are assumed to be known, whereas the second view has unknown distortion and calibration parameters. This situation arises e.g. when one would like to register archive imagery to recently taken photos. A commonly adopted strategy for determining epipolar geometry is based on feature matching and minimal solvers inside a RANSAC framework. However, only very few existing solutions apply to the calibrated-uncalibrated setting. We propose a simple and numerically stable two-step scheme to first estimate radial distortion parameters and subsequently the focal length using novel solvers. We demonstrate the performance on synthetic and real datasets.

Similarly to what has happened in other countries, since the early 1990s Portuguese companies have developed corporate environmental reporting practices in response to internal and external factors. This paper is based on empirical research directed to both the study of environmental reporting practices developed by Portuguese companies and the identification of the factors that explain the extent to which these companies disclose environmental information. This study focuses on the environmental disclosures made in the annual reports by a sample of 109 large firms operating in Portugal during the period 2002-04. Using the content analysis technique we have developed an index in order to assess the presence of the environmental disclosures in companies’ annual reports and their breadth. Based on the extant literature, several characteristics relating to firms’ attributes were selected and their influence on the level of environmental disclosure was tested empirically. The selected explanatory variables were firm size, industry membership, profitability, foreign ownership, quotation on the stock market and environmental certification. The results reveal that, in spite of the fact that the level of environmental information disclosed during the period 2002-04 is low, the extent of environmental disclosure has increased as well as the number of Portuguese companies that disclose environmental information. Moreover, the firm size and the fact that a company is listed on the stock market are positively related to the extent of environmental disclosure. This study adds to the international research on environmental disclosure by providing empirical data from a country, Portugal, where empirical evidence is still relatively unknown, extending the scope of the current understanding of the environmental reporting practices.

In recent years, several new coffee cultivars recommended for different regions have been released. However, the performance of these varieties in many traditionally producing regions is unknown. Difference of climate and soil may jeopardize the productivity of the new cultivars and cause losses to farmers. The objective of this study is to evaluate the vegetative growth and productive genotypes of C. arabica in the conditions of the Northwestern Rio de Janeiro State, Brazil. The experiment was settled in 2007, in Panorama 1 Farm, located in the municipality of Varre Sai, RJ. Twenty-five genotypes of C. arabica were planted in a spacing of 2.5 × 0.8 m, using a completely randomized design with five replications and eight plants per plot. There were eight measurements of vegetative growth represented by plant height, stem diameter and number of plagiotropic branches. Assessments of productivity were also performed in years 2009 and 2010. There was a positive phenotypic correlation among vegetative characteristics and between vegetative characteristics and yield in the first harvest, while in the second harvest only the number of plagiotropic branches was positively correlated with yield. Up to date, the genotypes Catucaí amarelo 2 SL, Catiguá MG 02, Acauã, Palma II, Sabiá 398, IPR 103/ Iapar, IPR 100/Iapar, H 419-10-6-2-12-1, Catucaí amarelo 24 / 137, Iapar 59, Catucaí amarelo 20/15, H 419-10-6-2-5-10-1 and H 419-10-6-2-5-1 had the highest average yield after two harvests.

This paper was developed with the intention of broadly demonstrating the complexity of the area known recently as character development, as a creative process methods and implementation. It searches the understanding of the character itself, its place in the narrative and its reception by the reader or target audience. It is a multidisciplinary tool that faces a multitude of challenges from an increasingly demanding public and with specific goals in mind, and yet it also gives us valuable insight over how we interact with one another and the world around us, teaching us how to transfer such knowledge into fiction promoting empathic bonds between the reader and the characters. The human tendency to create is limitless and as old as mankind itself, we create, recreate and reinterpret and then populate such tales with believable characters from who we learn, and experience events and tales that shape our very lives.

Purpose – Castings defects are usually easy to characterize, but to eradicate them can be a difficult task. In many cases, defects are caused by the combined effect of different factors, whose identification is often difficult. Besides, the real non-quality costs are usually unknown, and even neglected. This paper aims to describe the development of a modular tool for quality improvement in foundries, and its main objective is to present the application potential and the foundry process areas that are covered and taken into account. Design/methodology/approach – The integrated model was conceived as an expert system, designated Qualifound, which performs both qualitative and quantitative analyses. For the qualitative analyses mode, the nomenclature and the description of defects are based on the classification suggested by the International Committee of the Foundry Technical Association. Thus, a database of defects was established, enabling one to associate the defects with the relevant process operations and the identification of their possible causes. The quantitative analysis mode deals with the number of produced and rejected castings and includes the calculation of the non-quality costs. Findings – The validation of Qualifound was carried out in a Portuguese foundry, whose quality system had been certified according to the ISO 9000 standards. Qualifound was used in every management area and it was concluded that the application had the required technological requisites to provide the necessary information for the foundry management to improve process quality. Originality/value – The paper presents a successful application of an informatics tool on quality improvement in foundries.

Bovine herpesvirus 1 (BoHV-1) causes major losses in worldwide livestock, affecting the respiratory and reproductive tracts of bovine. In the past decades, the number of cases in Brazil has been gradually increasing. Therefore, it is important to assess the distribution of infection in different regions of the country. In the state of Espírito Santo (ES) the BoHV 1 infection rate in dairy cattle herds is unknown. Thus, the aim of this study was to detect neutralizing antibodies against BoHV-1 in serum samples from 1,161 non-vaccinated cows from 59 dairy cattle herds in 23 municipalities of the Metropolitan, North, Northwest and South macro-regions. The identification of seropositive cows was evaluated by the virus neutralization test. The results showed that of all serum samples evaluated 775 (66.75%) had neutralizing antibodies against BoHV-1. Moreover, all herds were found positive; however, the percentage of positive cows varied among regions; 49.06%, 62.15%, 67.21% and 80.04% for the Metropolitan, South, North and Northwest macro-regions, respectively. In this study, the results clearly indicate the dissemination of the viral agent in dairy cattle in the ES state, requiring the monitoring and control of diseases related to BoHV-1 infection.

O presente artigo apresenta uma perspectiva material de compreensão da relação entre os sujeitos e os media centrada no conceito de actividade. A partir da discussão deste conceito no contexto de diferentes abordagens no campo dos estudos da comunicação, pretendemos centrarmo-nos na denominada “teoria da actividade” para introduzir uma concepção da actividade enquanto vector central da relação entre sujeito e media. Esta relação constrói-se de acordo com esta perspectiva, não como uma relação passiva baseada na exposição, mas sim como uma relação produtiva de uso dos media enquanto objectos no contexto de actividades colectivas e individuais de objectivação de uma relação produtiva de consumo suportada na mediação de artefactos.

RESUMO: Esta dissertação tem como objectivo compreender a influência da ideologia do Estado Novo nos conteúdos inseridos no suplemento infantil Pim-Pam-Pum. Visa ainda relacionar, num determinado momento temporal o suplemento infantil de um dos jornais mais lidos da época O Século, com a ideologia do Estado Novo. Procura identificar os valores incutidos nos números a analisar no Pim-Pam-Pum num período de dois anos. O período histórico em análise do suplemento infantil Pim-Pam-Pum compreende os exemplares entre 1953 a 1955. Como principais conclusões do estudo retira-se que o suplemento infantil procurava educar o seu público de forma lúdica. Por outro lado, transmitia e incutia em colaboração com a família os principais valores salazaristas. A imprensa escrita passa a ser uma arma de propaganda ideológica do Estado Novo numa tentativa de conter informação desfavorável ao regime perante as pressões internas e externas. Com a institucionalização da censura após a segunda Guerra Mundial, a vigilância e o exame das publicações dos organismos competentes em colaboração com a própria auto-censura dos jornalistas, simplificou-se. No entanto a imprensa procurou cumprir com a sua missão de divulgação cultural e lúdica através de jornais diários, revistas e suplementos infantis. ABSTRACT:The aim of this dissertation is to understand the influence of the ideology of the "Estado Novo" in the contents inserted in the children's supplement Pim-Pam-Pum. It also aims to relate, in a certain historical period, the children’s supplement of one of the most important newspapers of the time, "O Século", with the ideology of the "Estado Novo". In addition, it intends to identify the values ingrained in the numbers to be analysed in Pim-Pam-Pum in a period of two years. The period under analysis of the children's supplement Pim-Pam-Pum includes the numbers from 1953 to 1955. One of the main conclusions of this study is that the children's aforementioned supplement aimed to educate its audience in a joyful manner. On the other hand, it transmitted as well as inculcated with the families’ collaboration the main Salazarist values. The press becomes a weapon of ideological propaganda of the "Estado Novo" in an attempt to keep harmful information to the regime from the internal and external pressures. With the institucionalization of censorship after the Second World War, the careful surveillance of publications by the competent and relevant organisms in collaboration with the censorship made by the journalists themselves, was simplified. However, the press tried to accomplish its mission of cultural and playful diffusion by means of newspapers, magazines and children's supplements.
