Abstract: One of the science education objective, based on relationships between science, technology, society and environment (STSE) is, to form citizens capable on evaluating and taking decisions about the scientific advances impact on society and environment. In a two-way perspective, understand relationships between STSE, provides a vision of science as a human construction and therefore fallible, changeable and not neutral. In this study, we present some results from a comparative study on the influence of ethical conceptions of the nature of science, in two groups of future biology teachers, one from Brazil and, another one from Portugal. For data collection we constructed an attitude scale of Likert-type, which was validated mathematically and semantically. Results shows strong influence of social values, as in transgenic products, where the students’ ideas varied according to the ethical discussions more present in each country.

American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.63048
Abstract: A native plant of Biome Pampa (Southern Brazil), the Glandularia peruviana (L.) Small species has been, until now, little studied as ornamental plant for use as mulch and formation of massifs. Whilst this species didn’t suffer any genetic improvement process, it is extremely ornamental by its color and size. In order to promote its comercial propagation and its use to improve the Pampa biodiversity, this study was conducted to know, as a ruderal plant native from South America, how the behavior of the plants was when employed plant propagation and use of artificial auxin on the cuttings. The test consisted of assessing the growth of cuttings treated or not with indol-butyric acid, analyzed at diferent ages, at 21, 24, 27 and 31 days in the University of Passo Fundo, Passo Fundo, Brazil. It was observed that the plant total dry mass values showed no standard of behavior, values for dry matter, whether of leaves, stem, root, shoot and total not responded to treatments and analyzed ages. The same occurred for specific leaf weight, plant height, number of green leaves, number of dead leaves, average leaf length and average number of stems. The lack of significant treatment and age effects may be explained by the plant primitiveness, which is ruderal, so its development has little influenced by the propagation practices.
Evaluation of XIS-Mobile, a Domain Specific Language for Mobile Application Development  [PDF]
André Ribeiro, Alberto Rodrigues da Silva
Journal of Software Engineering and Applications (JSEA) , 2014, DOI: 10.4236/jsea.2014.711081
Abstract: The great evolution of the mobile market during the last years caused some fragmentation of the mobile platforms namely through the existence of different programming languages and software development tools for each platform. This fact can be an obstacle and increases the development complexity and costs when we want to develop mobile applications for multiple platforms. The XIS-Mobile domain specific language (defined as a UML profile) and its MDD-based framework address this problem by proposing platform-independent models to describe mobile applications and from them automatically generate the application’s source code. Many issues arose during an iterative process of evaluation which originated changes and the evolution of XIS-Mobile. This paper presents the results of the evaluation of XIS-Mobile (both the language and the companion framework) obtained through the implementation of a case study and by conducting a user session, and discusses its benefits and challenges.
Data Modeling and Data Analytics: A Survey from a Big Data Perspective  [PDF]
André Ribeiro, Afonso Silva, Alberto Rodrigues da Silva
Journal of Software Engineering and Applications (JSEA) , 2015, DOI: 10.4236/jsea.2015.812058
Abstract: These last years we have been witnessing a tremendous growth in the volume and availability of data. This fact results primarily from the emergence of a multitude of sources (e.g. computers, mobile devices, sensors or social networks) that are continuously producing either structured, semi-structured or unstructured data. Database Management Systems and Data Warehouses are no longer the only technologies used to store and analyze datasets, namely due to the volume and complex structure of nowadays data that degrade their performance and scalability. Big Data is one of the recent challenges, since it implies new requirements in terms of data storage, processing and visualization. Despite that, analyzing properly Big Data can constitute great advantages because it allows discovering patterns and correlations in datasets. Users can use this processed information to gain deeper insights and to get business advantages. Thus, data modeling and data analytics are evolved in a way that we are able to process huge amounts of data without compromising performance and availability, but instead by “relaxing” the usual ACID properties. This paper provides a broad view and discussion of the current state of this subject with a particular focus on data modeling and data analytics, describing and clarifying the main differences between the three main approaches in what concerns these aspects, namely: operational databases, decision support databases and Big Data technologies.
Os Objetos ativos de Willys de Castro
Silva, Renato Rodrigues da;
Estudos Avan?ados , 2006, DOI: 10.1590/S0103-40142006000100017
Abstract: willys de castro has developed the objetos ativos (1959-1962) during the neoconcrete phase. in accordance with ferdinand de saussure's linguistics and jacques derrida's concept of "deconstruction", this article supports the idea that the originality of this series of objects is based on the inscription of "signs". thus, the visual and semantic analysis of the artist's discoveries - such as the "positive-negative motif" and the emphasis on the tridimensionality of the support, achieved in soma entre planos i (1959), objeto ativo de 1959, objeto ativo de 1960 and objeto ativo de 1962 - shows that these signs represent consecutive changes of pictorial and sculptural readings. we conclude that the unity of these works is found in the convergence to the "paradigm of perspective" to decline the correlative versions of painting and sculpture.

Revista Brasileira de Cirurgia Cardiovascular , 2006, DOI: 10.1590/S0102-76382006000400016
Abstract: objective: eighteen years ago, two young male patients of 8 months and 13 years with aortic coarctation associated to aortic hypoplasia between the left subclavian artery and the coarctated area, were submitted to surgical correction using a new world-pioneering surgical technique developed in our service. method: this technique consists of sectioning the patent ductus arteriosus, followed by resection of all the coarctated tissue in the aortic wall and aortoplasty correction by means of the lengthwise implantation of a pediculated autogenous pericardial flap. this flap is inserted into the thoracic aorta, from the root of the left subclavian artery to 2.0 cm below the coarctated area. results: for both patients, the blood pressure and arterial pulses of both arms and legs have been normal since the surgery until the present moment. clinical examination and doppler evaluation evidenced no pressure gradient between arms and legs, normal blood flow and no pressure gradient through the coarctated area. both patients were submitted to other evaluations 18 years after surgery, including cardiac and thoracic aortic catheterization followed by aortography. these evaluations demonstrated normal aortic configuration, with normal diameter, including the areas above and below the coarctated site. there was no evidence of any kind of degenerative lesions of the vascularized pericardial flap or re-coarctation of the lesion and no signs of aneurysms forming or the presence of atherosclerosis of the flap. moreover, and very importantly, it was evident that the pediculated completely vascularized autologous pericardial flap had been kept alive and had grown in diameter as well as in length. conclusion: the surgical technique using a pediculated vascularized autologous pericardial flap is the most complete and adequate for the correction of the different types of simple or complex forms of thoracic aortic coarctation in all age groups, including newborn babies when compared to all t
