Visual IMML: um perfil UML para a modelagem de interfaces de usuário

The software development processes proposed by the most recent approaches in Software Engineering make use old models. UML was proposed as the standard language for modeling. The user interface is an important part of the software and has a fundamental importance to improve its usability. Unfortunately the standard UML does not offer appropriate resources to model user interfaces. Some proposals have already been proposed to solve this problem: some authors have been using models in the development of interfaces (Model Based Development) and some proposals to extend UML have been elaborated. But none of them considers the theoretical perspective presented by the semiotic engineering, that considers that, through the system, the designer should be able to communicate to the user what he can do, and how to use the system itself. This work presents Visual IMML, an UML Profile that emphasizes the aspects of the semiotic engineering. This Profile is based on IMML, that is a declarative textual language. The Visual IMML is a proposal that aims to improve the specification process by using a visual modeling (using diagrams) language. It proposes a new set of modeling elements (stereotypes) specifically designed to the specification and documentation of user interfaces, considering the aspects of communication, interaction and functionality in an integrated manner

Abordagem dirigida a modelos para redes de sensores sem fio

Research on Wireless Sensor Networks (WSN) has evolved, with potential applications in several domains. However, the building of WSN applications is hampered by the need of programming in low-level abstractions provided by sensor OS and of specific knowledge about each application domain and each sensor platform. We propose a MDA approach do develop WSN applications. This approach allows domain experts to directly contribute in the developing of applications without needing low level knowledge on WSN platforms and, at the same time, it allows network experts to program WSN nodes to met application requirements without specific knowledge on the application domain. Our approach also promotes the reuse of the developed software artifacts, allowing an application model to be reused across different sensor platforms and a platform model to be reused for different applications

Políticas de turismo e comunidade local no litoral potiguar

This research focuses on raise the discussion of existance tourism policies in Rio Grande do Norte and its contributions to the integration of local communities in the coastal tourist activity. Guided by the background of the neoliberalism and its influence on the model of tourism development adopted in Rio Grande do Norte. For that, were surveyed the concrete realities of coastal localities of the municipalities of Ceará-Mirim, Extremoz, Parnamirim and Nísia Floresta covered by Prodetur-RN I and II, by being part of the tourist portion of the state that have received domestic and international investment and, because are located in the geographical area of the Potiguar capital, Natal. We interviewed the municipal managers and the residents of local communities who live in municipalities more than ten years. Also, was raised a discussion on the role of the state as the main agent of public policies and hegemonic facilitator in the attraction of domestic and foreign investments, with the main scenario the neoliberal model of economic development. Here discuss ways and strategies of socio-political organization of local communities, with regard to the inclusion in the tourist and, pointing to the critical development model in question and signaling other concepts of development model, such as local basis, for example. By the ending of the research, was concluded that the model of development of the tourism in the Rio Grande do Norte is reflected of the way of life of the society, that the communities live in precarious conditions and that the way of inclusion in the tourism is almost incipient. Also, it was possible to detect the inexistence of public politics of tourism that promoted the planning of the tourist activity, as well as, the inclusion of the communities in the decision processes and that, searched the development on the basis of the principles of sustainable and local autonomy

Variation in mandible shape in Thrichomys apereoides (Mammalia: Rodentia): Geometric analysis of a complex morphological structure

The model of development and evolution of complex morphological structures conceived by Atchley and Hall in 1991 (Biol. Rev. 66:101-157), which establishes that changes at the macroscopic, morphogenetic level can be statistically detected as variation in skeletal units at distinct scales, was applied in combination with the formalism of geometric morphometrics to study variation in mandible shape among populations of the rodent species Thrichomys apereoides. The thin-plate spline technique produced geometric descriptors of shape derived from anatomical landmarks in the mandible, which we used with graphical and inferential approaches to partition the contribution of global and localized components to the observed differentiation in mandible shape. A major pattern of morphological differentiation in T. apereoides is attributable to localized components of shape at smaller geometric scales associated with specific morphogenetic units of the mandible. On the other hand, a clinal trend of variation is associated primarily with localized components of shape at larger geometric scales. Morphogenetic mechanisms assumed to be operating to produce the observed differentiation in the specific units of the mandible include mesenchymal condensation differentiation, muscle hypertrophy, and tooth growth. Perspectives for the application of models of morphological evolution and geometric morphometrics to morphologically based systematic biology are considered.

Mild diabetes models and their maternal-fetal repercussions

The presence of diabetes in pregnancy leads to hormonal and metabolic changes making inappropriate intrauterine environment, favoring the onset of maternal and fetal complications. Human studies that explore mechanisms responsible for changes caused by diabetes are limited not only for ethical reasons but also by the many uncontrollable variables. Thus, there is a need to develop appropriate experimental models. The diabetes induced in laboratory animals can be performed by different methods depending on dose, route of administration, and the strain and age of animal used. Many of these studies are carried out in neonatal period or during pregnancy, but the results presented are controversial. So this paper, addresses the review about the different models of mild diabetes induction using streptozotocin in pregnant rats and their repercussions on the maternal and fetal organisms to propose an adequate model for each approached issue. © 2013 D.

Neostructuralism and heterodox thinking in Latin America and the Caribbean in the early twenty-first century

The thinking that has unilaterally dominated economic science for over five decades has recently come under intensive scrutiny and its validity and conceptual and empirical coherence are the subject of controversy. Thus the limitations of the prevailing paradigm for addressing the failures of free market economies have been laid bare. For Latin America and the Caribbean, these failures are structural in nature, as indeed structuralism proposed in its time. Neostructuralism delves more deeply into the issues addressed in structuralism, aiming to improve positioning in the international economy, boost productive employment creation, reduce structural heterogeneity and improve income distribution, while maintaining financial balances capable of sustaining changes in the sphere of production by means of social and State support. Far from being an insular system of thinking, neostructuralism is an open system that lends itself to dialogue with other philosophies that recognize the limitations of the dominant paradigm and object to its methodological monism. This book offers a fresh look at neostructuralism and heterodox thinking at the start of the twenty-first century. In a context shaped by the impacts of the worst economic and financial crisis since the Great Depression and by paradigmatic changes at the global level, it aims to carve out arenas for discussion between alternative lines of thinking in order to lay the foundations for a socioeconomically inclusive and environmentally sustainable model of development for the region.

Da fronteira à sustentabilidade?: o caso de Paragominas-PA

Paragominas constituiu um pólo do avanço da fronteira na Amazônia, vivenciando ao longo de sua história, um modelo de desenvolvimento orientado pela busca do crescimento econômico. Este modelo foi caracterizado pelo avanço de frentes econômicas, notadamente, a da pecuária e do extrativismo madeireiro, que resultaram em crescimento econômico associado a problemas sociais e degradação ambiental. A partir da primeira década deste século, são verificadas mudanças neste cenário, com mudanças na base produtiva e avanços significativos na gestão dos recursos naturais do município. O Projeto Paragominas Município Verde, iniciado em 2008, é apontado como um fato histórico que marca a transição da economia de fronteira para um modelo de desenvolvimento sustentável. O presente estudo demonstra que as mudanças verificadas no município são anteriores a este fato histórico e foram orientadas por razões de alterações na viabilidade econômica das atividades desenvolvidas e/ou por questões relativas aos novos padrões de consumo da economia globalizada, como características de uma nova fase da fronteira na Amazônia. Na nova fase da fronteira em Paragominas, a par do avanço das dimensões ambiental e ecológica, ainda persistem os desafios da promoção de um acesso mais democrático aos recursos naturais, de uma maior distribuição das riquezas geradas e de uma melhor qualidade de vida para seus cidadãos, problemas afetos à dimensão social de um processo de desenvolvimento mais abrangente, que caracterize de fato, um modelo de sustentabilidade.

Geografia dos movimentos socioterritoriais no Brasil de 2000 à 2012

The struggle for land is not a recent theme in Brazilian history. Since colonization, people have fought and resisted against oppression and injustice in the countryside, as can be evidenced by the highwaymen, peasant leagues and the war of Canudos. More recently, the struggle for land and agrarian reform can be evidenced by the struggles of the MST, CONTAG, CPT and other movements. For these movements, denominated as socioterritorial movements, land/territory is an essential condition for their existence and for the maintenance of their territoriality. The present paper examines the geography of socioterritorial moviments: the construction of the concept of socioterritorial movements and their forms of action and scales of actuation in the period 2000 to 2012, focusing on the movements that have been most active. These movements are studied through as analysis of data of the Land Struggle Data Base (Banco de Dados da Luta pela Terra –DATALUTA), print and digital media reports and a bibliographic survey of the literature. The action of socioterritorial movements can be studied through the forms of land occupations and demonstrations in the countryside which are the principal means of the struggle against large landholders, agribusiness and the State. These actions question the model of development which privileges agribusiness and, as such, are viewed by some as a hindrance to the development of the country. Over the years, the number of socioterritorial moviments, and their actions have oscillated due to a series of factors, such as repression (criminalization of members and violence against them), policies adopted by Brazilian governments and the contradictions inherent in very process of the spacialization of the struggle for land. These actions can be analyzed according to the scale of the struggle of the movements – municipal, micro-regional, state, macro-regional, and national

Controle e caos na formação de moléculas com pulso de laser

We investigate the formation of molecules under the action of external field acting during the atomic collision. To describe this process, the collision of atomic pairs, we use the Morse oscillator model driven The study was developed from the standpoint of classical mechanics by analyzing the sensitivity of the system with respect to initial conditions, the verification of chaotic dynamics associated with the process of formation of molecules with laser and analysis of system dynamics and the likelihood of photoassociation in response to the external field parameters

Estudo das políticas de obtenção dos assentamentos de reforma agrária no Brasil entre 1985 e 2009

Understanding the territorial transformations is important to the geographic knowledge, especially when it is related to structural questions as agrarian one. In this way, the land acquisition to agrarian reform enables us to understand some of these transformations, represented by territorialization of landless workers in rural settlements, that are concrete results of the struggle for land that boost the policies of agrarian reform in our country. The renewal of the agrarian structure is fundamental to the concept of land reform and also provides that advances social, political, cultural, economic, etc. Classified as a country with rates of the highest land concentration in the world, Brazilian government attempts to base his actions to take in the expropriation of land the main character of the land reform. However, new policies have been gradually used to obtaining the rural settlements, in a process that Fernandes (2010) called the reconceptualization of land reform. Starting in 1985, Brazil has 63% of the beneficiaries of land reform policies settled on expropriated land, the rest is a result of incorporation policies such as land regularization, of land reform and land purchase. Such policies generate changes in agrarian structure, that is the goal of land reform, but don´t concentrate to the land ownership. This attitude of the state in coping with the agrarian question is his response to the pressures of capitalist agriculture represented by landowners and agribusiness, coping catching an intense and uneven territorial dispute with peasant agriculture, in an attempt to impose its model of development for the field. The aimed of this present study is to understand better the land reform acquisition and its implications in the Brazilian territory, in order to understand it in their multiplicity.
