Fatores condicionantes na formação de aglomerados no turismo :um estudo da perspectiva dos empresários em região do litoral do Nordeste do Brasil

The tourism has been presented as an alternative of production for determined regions of the Country. In this scene, one perceives that it is necessary to observe where each locality is situated in order to face an highly competitive and globalized world. The data used on this work was collected on a field research with the entrepreneurs of the coast of the City of Parnamirim/RN. The main objective of this research was to analyze the conditioning factors in the formation of clusters on tourism, according to the perception of the entrepreneurs of the Association of the Entrepreneurs of the Coast of Parnamirim AELP, based on the competitive advantages showed on Porter s model, referring to the conditions of the production factors, the demand, the associated and support sector, the strategy and structure of the company. On the statistical treatment, descriptive analysis and crossed analysis were carried through. According to the data, the research suggests the existence of some determinative factors that can generate competitive advantages, that whwn integrated, can congregate attributes that allow the formation of a competitive tourist accumulation in a region of the northeast coast of Brazil. The research also evidenced that the entrepreneurs have a strong dependence of the governmental actions

Um estudo do aumento da capacidade de sistemas 3g WCDMA usando técnicas 3.5G de expansão do enlace reverso

The introduction of new digital services in the cellular networks, in transmission rates each time more raised, has stimulated recent research that comes studying ways to increase the data communication capacity and to reduce the delays in forward and reverse links of third generation WCDMA systems. These studies have resulted in new standards, known as 3.5G, published by 3GPP group, for the evolution of the third generation of the cellular systems. In this Masters Thesis the performance of a 3G WCDMA system, with diverse base stations and thousand of users is developed with assists of the planning tool NPSW. Moreover the performance of the 3.5G techniques hybrid automatic retransmission and multi-user detection with interference cancellation, candidates for enhance the WCDMA uplink capacity, is verified by means of computational simulations in Matlab of the increase of the data communication capacity and the reduction of the delays in the retransmission of packages of information

A Hora e o Nevoeiro: discurso épico, vontade de potência e mal-estar da modernidade no poema Mensagem de Fernando Pessoa

Considering articles written for Fernando Pessoa in 1912 about The new Portuguese poetry , where he already proclaimed the appearance of the Super-Camões, poet that would be able to revolutionize Portuguese literature e, concomitantly, to make resurging from rubble the Portuguese nation; we understand that, decades before the writing of Message, the poet was already armed with a Will of Power , expression of Friedrich Nietzsche that incorporate the idea of resurgence to the man like creator of news values. Fernando Pessoa believed to make his poetical word, the epic, restoring word of the ideas of Messianism and Fifth Empire as the pushing force of the new Portuguese largeness. However, we look for to investigate the conditions of Malaise that surround the universe of the poem and that restrict its capacity of action on the reality in its return, a time that the space destined in modernity to the poet and to his poetry hindered him of a devoted and positive action, We select therefore theorist like Sigmund Freud e Walter Benjamin

Pressupostos ontológicos para se pensar a nova tecnologia: técnica, informação e ser e tempo

La recherche presentée, realisée sur le domaine de la méthaphysique, s´agit de rassembler des pressupositions pour une fondamentation ontologique de la technologie de l´Information, basé sur la philophie de Martin Heidegger; foncièrement, sur l´analytique existentiel du Dasein dans l´ouvrage Être et Temps. À partir de la pensée sur ce qui est aujourd´hui , il s´agit d´investiguer sur quels fondaments la Nouvelle Tecnologie se fut érigée de façon a que nous sommes engajés au projet de numérisation des étants que en même temps que destine l´homme a l´oubli de l´Être, l´offre la possibilité de transformation. Le rapport entre la question de l´Être et la question de la technique est analysé comme des chemins croisés et dans ce carrefour il devient possible penser ce qui est technique, ce qui est information pour Heidegger et de quel façon les modes existentiels du Dasein sont prêtes pour caractériser l ´homme au sein de la tecnologie de l´information. Par cette appropriation, il reste penser comment c´est possible l´ouverture d´une perspective de reconduction de l´homme à la vérité de l´Être. Finalement, la structuration des fondements rends possible la réflexion discursive général: avec qui nous nous ocuppons, comme nous sommes, dans quelle direction nous nous acheminons, les thèmes générales, respectivement, des trois chapitres. Les points d´investigation du premier chapitre son: a) La caractérisation précise du Dasein, appuyé sur des considerations de Benedito Nunes, Hans-Georg Gadamer, Jacques Derrida et Rüdiger Safränski; b) Le concept de technique et son essence chez Heidegger; c) la distinction entre technique et technologie, appuyé sur le pensée de J. Ellul, Michel Séris, Otto Pöggeler, Michel Haar, Dominique Janicaud; c) Le concept de cibernetique chez Heidegger et chez Norbert Wiener; d) La caractérisation preliminaire d´information, l´analyse étimologique e philosophique, l´avis de Heidegger te les théories de Rafael Capurro; f) L´Analyse du phénomène de la numérisation des étants, des considérations de Virilio, et l´analyse d´un concept de virtuel avec Henri Bergson et Gilles Deleuze. Dans le deuxième chapitre, l´analyse des existentiels du Dasein vers le sommaire des fondements de base pour la caractérisation de la technologie de l´information comme un problème philosophique. Finalement, aprés avoir presenté les concepts introdutoires que délimitent le questionement, suivi par les indications et pressupositions ontologiques trouvés sur Être et Temps, le troisième chapitre disserte sur le péril, ce qui sauve et la sérénité, les trois mots-clés de la pensée heideggerienne sur la technique que permettent l´approche conclusif de la question

Hannah Arendt e a crise na educação como crise político-filosófica da modernidade

Este estudo busca esclarecer e discutir a reflexão de Hannah Arendt sobre a crise na educação no mundo contemporâneo enquanto crise político-filosófica da modernidade. Trata-se de explicitar de que forma o significado da educação está atrelado às condições de instituição, compartilhamento e conservação do mundo comum e humano. Com o intuito de reconstruir as análises da autora sobre os reflexos da crise político-filosófica da modernidade na esfera prépolítica da educação, esta pesquisa investiga de que modo o fim da tradição metafísica, o esfacelamento da autoridade, o obscurecimento da esfera pública e a moderna alienação do mundo promoveram uma profunda degradação das capacidades humanas de construir, conservar e compartilhar pela ação e pelo discurso um mundo que possa sobreviver e permanecer um lugar não mortal para seres que nascem e morrem. Palavras-chave: Hannah Arendt; Educação; Crise; Modernidade; Autoridade; Espaço Público.

Prospecção de genes de interesse biotecnológico : uma abordagem metagenômica

The total number of prokaryotic cells on Earth has been estimated at 4 to 6x1030 and only about 1% of microorganisms present in the environment can be cultivated by standard techniques of cultivation and plating. Therefore, it is a huge biological and genetic pool that can be exploited, for the identification and characterization of genes with biotechnological potential. Within this perspective, the metagenomics approach was applied in this work. Functional screening methods were performed aiming to identify new genes related to DNA repair and / or oxidative stress resistance, hydrocarbon degradation and hydrolytic activities (lipase, amylase and protease). Metagenomic libraries were built utilizing DNA extracted from soil samples collected in João Câmara RN. The libraries were analyzed functionally using specific substrate containing solid medium (hydrolytic activity), supplemented with H2O2 (DNA repair and / or resistance to oxidative stress) and liquid medium supplemented with light Arabian oil (activity, degradation of hydrocarbons). After confirmation of activity and exclusion of false-positive results, 49 clones were obtained, being 2 positive for amylase activity, 22 resistant to oxidative stress generated by H2O2 and 25 clones active for hydrocarbons degradation. Analysis of the sequences showed hypothetical proteins, dienelactona hydrolase, DNA polymerase, acetyltransferase, phosphotransferase, methyltransferase, endonucleases, among other proteins. The sequence data obtained matched with the functions tested, highlighting the success of metagenomics approaches combined with functional screening methods, leading to very promising results

Caracterização da neofobia alimentar em crianças de três a seis anos

Alimentation is essential in life. Concerning omnivores, characterized by the necessity of a varied diet to satisfy their metabolic needs, it is extremely advantageous the assumption of new foods. However, the assumption of new unknown foods is, potentially dangerous, because of possible intoxications. In this sense, one of the most important behaviors related to reducing risks is the so called food neophobia, characterized by the rejection of new foods and/or an ingestion of very little amounts. The aim of the present study was to investigate if age, sex and socio-economical status were able to influence food neophobia. The neophobia has been described in a range of 3-6 years old children taken both from public and private schools within the city of Natal-RN. Four different type of ice-creams, each one characterized by a different flavor, have been utilized. Two flavors were known to the young and the remaining two flavor were new. We didn't find significant differences between the investigated variables. However, the exploitation of data from the survey conducted showed that the ease or not to accept new foods obtained, was correlated with the variables under the same guidelines observed in literature. Aspects related to the stimulus used probably eased the neophobic answer. Then, it is suggested that the food neophobia can be influenced by sex, age and socioeconomic factors of individuaIs. Neophobia tends to be more common in girls, with ages between three to four years old and with a low leveI socioeconomic. In this sense, given the importance of kid neophobic reaction to the development of dietary patterns of other life's stages, it is necessary to make further studies to better explain this phenomenon. Given the pivotal role of food neophobia to the development of alimentary habits within all ages of life, other studies will be necessary for a better comprehension of such phenomena.

Sentidos e perspectivas atribuídos por crianças à sua condição de estar para adoção

Considering the Brazilian current context, where many children are in institutional shelter waiting for adoption, the aim of this study was to know the meaning that sheltered children (whose families had already lost their custody or were in the process of losing it, at the moment of the field work) gave to their adoption condition. The research was carried out with three children in the shelter where they lived, in Natal, Rio Grande do Norte, Brazil. The field work took six months approximately. In order to meet the objective of this research, individual procedures were structuralized using figures and drawing material. With these procedures the children could speak directly or indirectly about the application of the legal measure of institutional shelter, about their lives before the application of this legal measure and what happened since then, and their original families and future perspectives. The content of the procedures was tape recorded and registered in the field work diary. The analysis of the corpus occurred with the Thematic Content Analysis, considering the theoretical methodological perspective of the Net of Meanings approach. The analysis of the corpus showed the ambiguity of the children, who consider good to live in the institution where they are, recognizing the responsibility of the original caregivers for their sheltered condition and, at the same time, they miss their relatives and wish to be with them. The subjects recognize the perspective of adoption and imagine it in a positive way. However, when the children were questioned about what could happen to them in the future, they said that they did not know, expressing uncertainty concerning their destinations

A água nossa de cada dia : percepção, uso e predisposições comportamentais de alunos do ensino médio de Natal, Rio Grande do Norte

Embora a escassez de água seja reconhecida como um dos principais problemas mundiais a ser enfrentado pela humanidade, padrões comportamentais ecologicamente insustentáveis ainda persistem. Assim, o objetivo deste estudo foi analisar determinantes do comportamento pró-ambiental relativo à água, bem como os significados que lhe são atribuídos por alunos do ensino médio do Centro Federal de Educação Tecnológica do Rio Grande do Norte, em Natal. Compuseram a amostra de conveniência 315 estudantes, 146 mulheres e 169 homens, que responderam a um questionário sobre uso e percepção da água, contendo também indicadores de pró-ambientalismo, cuidado ambiental, desenvolvimento sustentável, perspectiva temporal, externalidades e coletivismo, além de inquérito sócio-demográfico. Para os participantes, água é sinônimo de vida, muito embora a relação que mantém com ela parece dúbia e, muito mais funcional que ecológica; consideram-na um recurso finito, um patrimônio indispensável à vida, contudo não foi observada coerência entre as concepções manifestadas e os comportamentos auto-relatados de uso da água. Os resultados encontrados apontaram preditores importantes do comportamento pró-ambiental relativo à água: sexo do respondente, Escala Novo Paradigma Ecológico e deixar forma de contato para participar de campanhas futuras. Seja para aprofundamento teórico em novos estudos, seja para auxiliar na elaboração de programas de educação ambiental, que poderiam contribuir para inibir os efeitos de uma cultura de consumo e de uma visão utilitarista da água, ampliando esforços individuais e coletivos para a preservação de bens comuns, como a água. Palavras-chave: psicologia ambiental; sustentabilidade; água; comportamento próambiental. x xi Abstract Although water scarcity is recognized as one of the main world-wide problems to be faced by human kind, ecologically unsustainable patterns of behavior still persist. Thus, the objective of this study was to analyze pro-environmental behavior related to water, as well as meanings associated to it by high school students of Federal Center of Technological Education of Rio Grande do Norte, in Natal. The convenience sample was composed by 315 students, 146 women and 169 men, who answered a questionnaire about use and perception of water, containing indicators of proenvironmentalism, environmental care, sustainable development, time perspective, externalities and collectivism, besides socio-demographic items. According to participants, water is synonymous of life, even though the relationship they present with it is ambiguous, much more functional than ecological; they consider it a finite resource, an indispensable life patrimony, however there was no coherence between such conceptions and the self-reported behaviors of water use. Results indicated three important predictors of pro-environmental behavior: sex of respondent, New Ecological Paradigm Scale and telephone/address left for eventual contact to participate in future environmental campaigns. They may be used in additional studies for theoretical development, or to assist in the planning of programs of environmental education, aimed at the inhibition of the effects of a culture of consumption and of an utilitarian perception of water, extending individual and collective efforts towards the preservation of common resources as water

Compromisso social do psicólogo em artigos publicados em periódicos científicos no Brasil

Psychologist s social commitment in scientific articles published in scientific papers in Brazil. A situation analysis of the scientific production concerning psychologist s social commitment can aid the historical constitution of this theme and also subsidize reflections about the course of this profession in Brazil. In order to contribute to this debate, the theme social commitment of psychologist was analyzed in the scientific literature concerning psychologist profession in the country. Specifically, papers about the profession that mentioned the theme social commitment were characterized and their approach of this matter was analyzed. In order to accomplish these goals, two research stages were fulfilled: first, in a systematic search for scientific literature in internet databases, studies about the psychologist profession in the country were gathered; in the second stage, scientific papers relating to social commitment in their titles, abstracts or keywords were selected. 61 papers were retrieved, organized in electronic database and full-text analyzed, based in two axis: scientometric and thematic. The papers were identified, in general, as recent, of theoretic character and aligned with several Psychology subareas; mainly produced in public universities, in country s southwest; were of conjunctural interest to the authors research projects, individually published, by professors in touch with post-graduation; published in open access journals, with high Qualis evaluation. It was verified that there is no consensus on the meaning of the theme, prevailing definitions concerning the understanding of the social reality, to the majority of people or to a progressive-aligned professional performance. Are adduced as committed agents: the psychologist (sometimes together with other kinds of professionals or with users), the academia, and the representative entities of the profession. Depending on the subareas and the nature of study, all papers mentioned at least one of the following criteria: expansion of target-audience, renewal of practices, political direction, defined theoretical approach or adequate technical competence, sometimes relating each other. In short, psychologist s social commitment is a contradictory issue which have earned projection in scientific literature, reiterating the historical custom of evaluate the psychologist profession. As conclusion, it is regarded as indispensable to intensify the reflection about the role whose psychologist plays in a class-cleaved society and the limits and potentials of his performing in that framework.

Currículo e deficiência: análise de publicações brasileiras no cenário da educação inclusiva

A educação inclusiva envolve dimensões político-administrativas e pedagógicas. O currículo é umas dessas dimensões, e as adequações curriculares aparecem como uma estratégia para que sejam atendidos os princípios de uma escola para todos. Este estudo objetiva caracterizar o campo de estudos da educação inclusiva, por meio de uma revisão da literatura publicada entre os anos 2000 e 2010, em periódicos da área de educação, disponíveis no banco de dados Scielo. As palavras-chave utilizadas foram curricular, currículo, deficiência, educação especial e necessidades especiais. Os resultados demonstram que as produções na área são escassas no que diz respeito às estratégias para efetivação da educação inclusiva, limitando-se, prioritariamente, a reflexões e discussões teóricas que envolvem os princípios e políticas educacionais, pouco retratando experiências didático-pedagógicas que promovam ajustes curriculares e/ou formas de flexibilização do ensino.

O problema do caixeiro alugador com coleta de bonus: um estudo algoritmico

This paper introduces a new variant of the Traveling Car Renter Problem, named Prizecollecting Traveling Car Renter Problem. In this problem, a set of vertices, each associated with a bonus, and a set of vehicles are given. The objective is to determine a cycle that visits some vertices collecting, at least, a pre-defined bonus, and minimizing the cost of the tour that can be traveled with different vehicles. A mathematical formulation is presented and implemented in a solver to produce results for sixty-two instances. The proposed problem is also subject of an experimental study based on the algorithmic application of four metaheuristics representing the best adaptations of the state of the art of the heuristic programming.We also provide new local search operators which exploit the neighborhoods of the problem, construction procedures and adjustments, created specifically for the addressed problem. Comparative computational experiments and performance tests are performed on a sample of 80 instances, aiming to offer a competitive algorithm to the problem. We conclude that memetic algorithms, computational transgenetic and a hybrid evolutive algorithm are competitive in tests performed
