Germinação de sementes de Mimosa caesalpiniaefolia Benth. em diferentes substratos e temperaturas

A Mimosa caesalpiniaefolia Benth. é uma espécie nativa da região Nordeste, que vem sendo progressivamente cultivada do Maranhão ao Rio de Janeiro. A planta apresenta grande potencial para arborização, cerca viva e produção de madeira. O presente trabalho teve como objetivo definir o tipo de substrato, a temperatura, o tempo médio e a frequência relativa de germinação, para auxiliar a condução de testes de germinação e vigor em sementes de Mimosa caesalpiniaefolia. Para tanto, realizou-se um experimento no Laboratório de Análise de Sementes do CCA-UFPB, em Areia-PB, em delineamento inteiramente casualizado com os tratamentos distribuídos em esquema fatorial 4x4, com os fatores temperaturas (20, 25, 30ºC constantes e 20-30ºC alternadas) e substratos (entre papel, sobre papel, entre areia e entre vermiculita), em quatro repetições de 25 sementes. Foram analisados os seguintes parâmetros: porcentagem de germinação e de plântulas anormais, primeira contagem da germinação e velocidade de germinação, tempo médio e frequência relativa de germinação, massa fresca e massa seca de plântulas. A temperatura de 25ºC mostrou-se mais adequada para a condução dos testes de germinação e vigor em sementes de Mimosa caesalpiniaefolia, independentemente do substrato utilizado. O substrato entre papel foi o mais apropriado para avaliação da qualidade fisiológica das sementes e a sincronização do processo germinativo foi maior no substrato entre papel, independentemente da temperatura empregada.

Avaliação da interação universidade - empresas - governo no desenvolvimento de projetos inovadores no RN por micro e pequenas empresas

Knowledge and innovation were seen as major forces, both for survival, as the acquisition of competitive advantages in the Brazilian economy, as well as adding value to the product as a market differentiator. The Triple Helix model is directed toward the knowledge-based economy. Over the past six years, the Federal Government through the Financier of Studies and Projects ( FINEP ) invested in technological innovation projects, economic subsidies, about U.S. $ 1 billion supporting more than 800 projects with these resources. According to the MCTI , the Northeast, over the years 2000 to 2010 increased spending on Science and Technology (considering the activities of research and development more scientific and related activities) of the State Government in relation to its total revenue In 2000, 0.51% of total revenues were invested in Science & Technology, while in 2010 this figure increased to 1.31%. Among the nine Northeast states, Paraíba is highlighted. In 2000, 0.33% of its total revenues were directed to innovation, reaching 2.04% in 2010, the largest increase in the region while the RN invested 0.24% in 2000 and in 2010 reached the level of 1.42 %. According to IBGE, in the period 2000-2011, the micro and small enterprises surpassed the barrier of 6 million establishments. In 2000, there were 4.2 million establishments while in 2011 were 6.3 million active establishments. Therefore, throughout the period, there was a creation of approximately 2.1 million new establishments. Between 2000 and 2011, micro and small businesses have created 7.0 million formal jobs, 8.6 million jobs in 2000 to 15.6 million in 2011. This scenario shows the importance of this study in relation to the investment of governments in RD & I in micro and small enterprises. This study aims to analyze the interaction Universities - Business - Government in the development of innovation in micro and small companies in Rio Grande do Norte participants of the edicts of Inova FAPERN. We chose to adopt as a research method case study concerning the procedure of the research, exploratory, descriptive, and on documents with engineers and researchers of innovation projects approved by PAPPE Subsidy (Inova -RN I, II and III). Data collection was done through the report made by FAPERN entitled: " Evaluation of companies financed and supported by the Grant Program for Technological Innovation for Micro and Small Enterprises RN - INOVA -RN " (2010) and a questionnaire with 40 closed questions and 1 opened to 30 affirmative composed based on a 5-point Likert scale. The analysis of data was qualitative and quantitative. The study provided to identify the importance and barriers arising from the relation between Government Enterprise (micro and small) and University as essential to the economic development of the region. It was also identified that, in the innovation projects, 70% of the goods or services originating from research were to market these, 50% resulted in a patent for the company and 80% publications of scientific articles

Uma abordagem para manipulação de informações geográficas utilizando Scalable Vectors Graphics

In this work, we propose a Geographical Information System that can be used as a tool for the treatment and study of problems related with environmental and city management issues. It is based on the Scalable Vector Graphics (SVG) standard for Web development of graphics. The project uses the concept of remate and real-time mar creation by database access through instructions executed by browsers on the Internet. As a way of proving the system effectiveness, we present two study cases;.the first on a region named Maracajaú Coral Reefs, located in Rio Grande do Norte coast, and the second in the Switzerland Northeast in which we intended to promote the substitution of MapServer by the system proposed here. We also show some results that demonstrate the larger geographical data capability achieved by the use of the standardized codes and open source tools, such as Extensible Markup Language (XML), Document Object Model (DOM), script languages ECMAScript/ JavaScript, Hypertext Preprocessor (PHP) and PostgreSQL and its extension, PostGIS

Validação de uma metodologia de ensaio de resistência ao cisalhamento para avaliação da aderência de interfaces revestimento metálico-bainha de cimento aplicada a poços de petróleo

Improving the adherence between oilwell metallic casing and cement sheath potentially decrease the number of corrective actions present/y necessary for Northeastern wells submitted to steam injection. In addition to the direct costs involved in the corrective operations, the economic impact of the failure of the primary cementing aIso includes the loss in the production of the well. The adherence between casing and cement is current/y evaluated by a simple shear tests non standardized by the American Petroleum Institute (API). Therefore, the objective of the present is to propose and evaluate a standardized method to assess the adherence of oilwell metallic casing to cement sheath. To that end, a section of a cemented oilwell was simulated and used to test the effect of different parameters on the shear stress of the system. Surface roughness and different cement compositions submitted or not to thermal cycling were evaluated. The results revealed that the test geometry and parameters proposed yielded different values for the shear stress of the system, corresponding to different adherent conditions between metallic casing and cement sheath

Diagnóstico regional do processo de queijo coalho comercializado em Natal/RN

Coalho cheese is a typical product of the Northeastern Brazil, which is consumed both raw and cooked. The present work aimed to study the characteristics of artisanal and industrial processes in the production of coalho cheese sold in Natal / RN in order to evaluate its quality and consumer s profile. Four artisanal cheeses plants were monitored and a questionnaire was sent to different cheese industries. Besides this, eight cheese samples (four artisanal and four industrial) were evaluated in regard to the microbiological quality, physical-chemical and sensory attributes. The sensory acceptance was evaluated by using 108 non-trained panelists by using the hedonic scale. The consumer s profile survey was applied to 400 consumers of coalho cheese. The lack of hygiene control was detected at the artisanal cheese production, which uses raw milk as its raw material. Research has shown that the industrialized cheeses are made from pasteurized milk provided by their own production or by a third party, as observed in cheese making dairies. In general, the results indicate variation in the manufacturing process of coalho cheese, which results in the lack of product standardization. Regarding the physical-chemical analysis, most artisanal and industrial samples presented moisture content between 36 and 40 %, classified as medium moisture cheese, which is the only parameter that showed no significant difference (p>0.05). However, the water activity (Aw), pH and acidity results differed significantly. All artisanal samples showed coliform contamination at 35 °C, which confirms the poor hygienic conditions. In regard to coliforms at 45 °C, 75 % of artisanal coalho cheese samples had value higher than 103 MPN / g, a value above the lawful limits determined by RDC nº 12. Fifty percent of industrial coalho cheese samples showed coagulase-positive Staphylococcus values above the limit allowed by the RDC nº 12, indicating poor handling. The sensory evaluation revealed that the taste was the only parameter that showed significant difference, and this difference was only between two industrial brands. The consumer s survey showed that the coalho cheese flavor is the most important reason for buying this kind of cheese. Although coalho cheese is mainly bought in supermarkets, open street markets and country shops are still important selling points. It is concluded that there is no coalho cheese standardization in the RN state, which leads to variations in physical-chemical and sensory attributes. Moreover, it is necessary greater hygiene control in the production and handling procedures of coalho cheese.

Gilberto Freyre e Câmara Cascudo: entre a tradição, o moderno e o regional

The present work makes some comments on the scattered productions of Gilberto Freyre and Luís da Câmara Cascudo, in the period which includes the early years of their intellectual performance, the second decade of the twentieth century. The corpus of the research is delimited on the texts published by Gilberto Freyre, from 1918 to 1926, which were gathered in the book Tempo de aprendiz (1979), and from the ones published by Câmara Cascudo in Natal local newpapers, such as A Imprensa and A República, in 1924, 1927, 1928 and 1929. Concerning Câmara Cascudo s texts, the delimitations of these years is due to they had a relevant importance for the literary and cultural history of Rio Grande do Norte. The included discussions in these writers texts mainly happen around the modernist and regionalist ideas that happened restrictively in the Northeast region of Brazil, and are based on the relationships between literature and culture. Thus, the set of collaborations of both writers is useful as a sample of the intellectual thinking of the mentioned region. Besides, it is representative in the way the cultural debate got along in the country, which in turn, demanded the inclusion of the local realities in order to follow the renewing process of the worldwide thinking, and as matter of fact, arrange a new process in the Brazilian literary tradition. In this way, the study goals to set the positions taken by the two writers faced to the new challenges that the Brazilian reality of that moment was imposed on. The theoretical basis of this work is focused on the accumulated studies about the Brazilians modernism, regionalism and literature, pointing out the Candido s texts, (2006, 2004, 2002, 1995, 1993 and 1989), Schwarz s (1999, 1997a and 1997b), Perrone- Moysés s (2007), Pallares-Burque s (2005), Azevedo s(1996), D Andrea s (1992), Araújo s (2006, 1998, 1997 and 1995), among other authors. Therefore, It is relevant the participation of both writers in that moment which highlights the renewing of the national thinking and the formation of the Brazilian cultural modernity, even the positions taken by them reveal, at times, different views concerning literature and tradition without being disagreeing, however

Prospecção e caracterização de genes associados ao processo de indução floral em cana-de-açúcar

The northeastern region is responsible to 14.32% of sugarcane national production. This lowered contribution is due to edaphoclimatic condition. Flowering is a vital process to plant which consumes lots of energy and it culminates in a process called isoporization. This one can give in a decreasing of 60% on alcohol and water production. It may consider that cropped sugarcane has a hibrid with octaploid genome, there are varieties with a flowering standard until of non flowering. Using this natural genetic potential on different croppings of sugarcane, the aim of this work was to understand as this process occurs by the usage of subtractive approaches. The total RNA was extracted using Trizol of peaks of merisematics of croppings with induced flowering and other with late flowering. From this total RNA were built four subtractives libraries (B1- induced early flowering subtracted on late flowering not induced; B2- late flowering not induced subtracted induced early flowering; B3- induced early flowering subtracted of not induced early flowering; B02- not induced early flowering subtracted from induced early flowering) using kits Super Smart cDNA synthesis and BD Clontech kit select cDNA subtraction (Clontech). This material was clone don vector pGEM T-easy(Promega) and changed in competent cells of E.coli DH10B. Given analysis sequence was carried out a program BLASTn against database of NCBI and genome of Arabidopsis thaliana, rice and maize. Clones were grouped in 9 different classes according to function. Some factors already related as couples of flower induction were identified at different libraries. And grouped proteins with cell cycle and it controls were presents, mainly kinases proteins. Related factors to proteic sinthesis, metabolism, defence, cell communication were also given in both libraries .Some identified genes did not show similarity on database or homology with hypothesis function, and it can represents new genes to be deposited in international database. These results offers that some identified on sugarcane, classified as on factors classes, cell cycle and cell communication, trough unknown genes, can be linked with genetic changing to the flowering process found in the northeastern region

Uso de ferramentas por macacos-prego em manguezais

The present study discusses the geographical distribution and the context on the occupation of mangrove swamp areas by capuchin monkeys. In addition, we assess how the dispersion to the mangrove allowed the exploration of different food items, permitting the development of predation by ambush and the use of cracking tools. From 2004 to 2008 we surveyed the main estuaries of Brazilian Amazon coast, from northeastern state of Pará to the eastern boundary of the state of Maranhão, and recorded the presence of two species of capuchin monkeys in the mangrove forest areas. Cebus apella has been widely distributed in the mangrove at the estuaries examined (excluding C. libidinosus areas). Its presence is often related to Amazon forest remnants in the neighbourhood of the mangrove swamps and thus it is possible that some groups live in both kinds of habitats. However, we recorded some populations restricted only to mangrove swamp surrounded by open areas. On the other hand, Cebus libidinosus had a distribution more restricted and isolated in mangroves. Its pattern of habitat use is consistent with geographic distribution in mangrove patches. It seems that the possible contact zone previously proposed in the literature for that two species has no evident barriers in the mangrove. Furthermore, we record cracking sites and systematic observations on the tool use, carnivory and predation by ambush in Cebus libidinosus from 2006 to 2008. Cebus libidinosus is the only Neotropical primate species in which the tool use has been systematically recorded in nature. However all previous studies had been obtained is open areas (Cerrado and Caatinga). Thus, the present study is first one to report that behaviour in forested habitats in which the tool use to cracking by capuchin monkeys is associated with the consumption of meat. In the Caatinga and Cerrado, food shortages and terrestriality has been proposed by different authors to explain the evolution of tool use in primates. Here, we analyzed the relative contribution of these two variables as selective pressures for the tool use by capuchin monkeys in the mangrove forests, an ecological scenario in which food resources is available around the year and terrestriality is limited by structural habitat features, as the presence of stilt roots and muddy soil

Relação entre padrão comportamental, estágios do ciclo de muda e atividade de enzimas digestivas proteolíticas em juvenis do camarão marinho Litopenaeus vannamei (Crustacea: Penaeidae)

Shrimp farming in Brazil is a consolidated activity, having brought economical and social gains to several states with the largest production concentrated in the northeast. This fact is also reflected in higher feed intake, necessitating a more efficient feed management. Currently, management techniques already foresee food loss due to molting. In this sense, studies relating shrimp s digestive physiology, molting physiology and behavioral response of shrimp feed can optimize the feed management. Thus, our study aimed to evaluate the behavioral response of the marine shrimp L. vannamei (Crustacea: Penaeidae) in accordance with the stages of moulting cycle and feeding schedules based on higher or lower activity of proteolytic digestive enzymes; also, to investigate the influence of feeding schedule on hepatosomatic index and non-specific and specific protease activity (trypsin). Experiments were carried out at the Laboratory of Shrimp Behavioral Studies at UFRN in partnership with the Laboratory of Enzimology UFPE. Juveniles of L. vannamei weighting 5.25 g (+ 0.25 g) were kept in aquaria at a density of 33 shrimp m -2. In the first experiment, shrimp were fed in the light phase or in the dark phase for 8 days; in the ninth day, the animals were observed for 15 minutes every hour during the 12 hours of each phase of the photoperiod. We recorded the frequency of inactivity, exploration, food intake, burrowing, swimming and crawling behavior. At the end of the 12th observation session, the shrimp were sacrified and classified by the method of setogenesis in the molt cycle stages A, B, C, D0, D1, D2 or D3. We found that the shrimp in A stage show high levels of inactivity. Moreover, the frequency of food intake was very low. The shrimp in D3 stage also had low food intake and high inactivity associated with elevated frequencies of burrowing. In the second experiment, shrimp were kept in physiological acclimation to experimental conditions for 28 days, distributed in 12 treatments in the light phase and 12 treatments in the dark phase. In the end, the animals were sacrified and dissected to assess non-specific and specific protease activity (trypsin) activity. In general, these parameters did not vary among animals fed in the light phase and those fed in the dark phase. However, significant differences were found in the activity of specific and nonspecific proteases in relation to food treatment. In the light phase, the major proteolytic activities converged to 10 hours after the start of the light phase, while the lowest activities converged to 6 hours after the beginning of this phase. In the dark phase, the highest enzyme activity converged to 12 hours after the onset of phase, while the lowest activities converged to 3 hours after the onset of phase. In the third experiment, we sought to evaluate the behavioral responses of shrimp in relation to dietary treatments based on higher or lower activity of proteolytic enzymes, considering the results of the second experiment. The behavioral categories observed were the same as the ones in the first experiment, with observations of 30 minutes (15min before and 15min after food supply). We found variation in behavioral responses as a function of the treatments, with greater intake of food in shrimp fed during the period of greatest activity of proteolytic enzymes, in the light phase. Thus we see that periodic events associated with the shrimp s physiology interfere in their behavioral responses, revealing situations that are more adjustable to the provision of food, and consequently optimizing feeding management

Padrão de distribuição e caracterização morfológica de fibras serotonérgicas nos núcleos da linha Média/ intralaminares do tálamo do mocó (Kerodon rupestris)

The midline/intralaminar nuclei form a remarkable group of nuclei of the medial and dorsal thalamus. The midline nuclei, in rats, comprises the paratenial nuclei (PT), paraventricular (PV), intermediodorsal (IMD), reuniens (Re) and rhomboid (Rh). The intralaminar nuclei comprises the central medial (CM), paracentral (PC), central lateral (CL) and parafascicular (PF). Such nuclei have dense serotonergic innervation originating from the brainstem, especially from the so-called ascending activation system. These nuclei, in turn, send projections to various cortical and subcortical areas, specifically to limbic areas, which suggests the important role of this neurotransmitter in the limbic circuitry. The aim of this study was to characterize the distribution pattern and morphology of serotonin fibers in the nuclei of the midline and intralaminar thalamic of rocky cavy (Kerodon rupestris), a tipical rodent from brazilizan northeast. To reach this aim we used four rock cavies adults. Following the transcardially perfusion with paraformaldehyde and brain microtomy steps was performed immunohistochemistry for serotonin (5-HT), Nissl technique and subsequent achievement and image analysis to characterize the cytoarchitecture of these nuclei and the serotonergic fibers visualized. An analysis was made of Relative Optical Density (ROD) to semi-quantify the concentration of serotonin fibers in the areas of interest. Thus, we observed a cytoarchitectonic arrangement of these nuclei similar to that found in rats. In case of fibers distribution, those immunoreactive to 5-HT were presented in a higher concentration according as ROD in the midline nuclei relative to intralaminar; Re being the core which has a higher pixel value followed by the PV , Rh, IMD and PT. In intralaminar CL showed higher pixels, followed by nuclei CM, PC and PF. The serotonergic fibers were classified as number of varicosities and axon diameter, therefore find three types of fibers distributed through this nuclear complex: fibers rugous, granular and semi-granular. In PV fibers predominated rugous; in PT fibers predominated granular; IMD, CL and PF fibers were represented by semi-granular and Re, Rh, PC and CM fibers showed granular and semi-granular. Morphological characterization of serotonergic fibers and differences in density between the nuclei may suggest different patterns of synaptic organization of this neurotransmitter beyond confirming his large repertoire functional

Tomada de decisão de Psicólogos em avaliação Psicologica

Psychological assessment is a procedure that is inserted in all areas of a psychologist s professional field of work. When starting any psychological intervention, it is necessary to carry an analysis of how individual operate in order to identify and define their demands to adequately meet them. It is important to study this practice because the choice of instruments, techniques and procedures to be employed influences the efficiency and effectiveness of the work and the image of the profession towards society in general, also impacting the scientific community. This study aimed to identify, in the subjects, the percentage of professionals in psychology who make use of the Psychological Assessment in the Northeastern region of Brazil; another objectives were to analyze the profile of these professionals in terms of gender, time after graduation, additional training in PA, the state of the country where he/she works; to check how psychologists do their planning when using PA as well as to identify which differences can be observed in terms of time from graduation and additional training in the process of planning the assessment different extents. The instrument used was an online questionnaire and the sample was by adhesion to the application. The attendance was of 159 professionals and most of them were females with a specialist degree. It was found that the majority of the professionals perform the planning of the PA, establishing a method and choosing the most appropriate strategies to be used. It was also verified that most of the subjects fulfill the steps of the whole process, and when planning the techniques of data collection, integrating database from different sources, reporting the results and returning the information, the professional demonstrates his/her goals to understand their demands and accomplish the decision making and/or proposed intervention for individuals assessed. It was found that the undergraduate degree may not have produced a more complete effect in the professional qualification and therefore, of the quality of the actions in PA, and that there is a need for training and continuing education

Novas formulações de fluidos de corte: otimização, propriedades e recuperação do óleo usado

Cutting fluids are lubricants used in metal-mechanical industries. Their complex composition varies according to the type of operation carried out, also depending on the metals under treatment or investigation. Due to the high amount of mineral oil produced in Northeastern Brazil, we have detected the need to better use this class of material. In this work, two novel formulations have been tested, both based on naphthenic mineral oil and additives, such as: an emulsifying agent (A), an anticorrosion agent (B), a biocide (C) and an antifoam agent (D). Each formulation was prepared by mixing the additives in the mineral oil at a 700-rpm stirring velocity for 10 min, at 25°C, employing a 24 factorial planning. The formulations were characterized by means of density, total acid number (TAN), viscosity, flash point and anticorrosion activity. In a subsequent study, oil-in-water emulsions were prepared from these novel formulations. The emulsions were analyzed in terms of stability, corrosion degree, percentage of foam formation, conductivity, accelerated stability and particle size. The samples were appropriately labeled, and, in special, two of them were selected for featuring emulsion properties which were closer to those of the standards chosen as references (commercial cutting oils). Investigations were undertaken on the ability of NaCl and CaCl2 to destabilize the emulsions, at concentrations of 2%, 5% and 10%, at an 800-rpm stirring velocity for 5 min and temperatures of 25º, 40º, 50º and 60ºC. The recovered oils were chemically altered by reincorporating the same additives used in the original formulations, followed by preparation of emulsions with the same concentrations as those of the initial ones. The purpose was to assess the possibility of reusing the recovered oil. The effluents generated during the emulsion destabilization step were characterized via turbidity index, contents of oil and grease, pH, and contents of anions and cations, observing compliance with the parameters established by the current environmental legislation (Brazil s CONAMA 357/05 resolution). It could be concluded that the formulations presented excellent physicochemical properties as compared to commercial cutting fluids, showing that the quality of the newly-prepared fluids is superior to that of the formulations available in the market, enabling technically and environmentally-safe applications

Estruturas tectônicas cenozóicas na porção leste da Bacia Potiguar - RN

This thesis encompasses the integration of geological, geophysical, and seismological data in the east part of the Potiguar basin, northeastern Brazil. The northeastern region is located in South American passive margin, which exhibits important areas that present neotectonic activity. The definition of the chronology of events, geometry of structures generated by these events, and definition of which structures have been reactivated is a necessary task in the region. The aims of this thesis are the following: (1) to identify the geometry and kinematics of neotectonic faults in the east part of the Potiguar basin; (2) to date the tectonic events related to these structures and related them to paleoseismicity in the region; (3) to present evolutional models that could explain evolution of Neogene structures; (4) and to investigate the origin of the reactivation process, mainly the type of related structure associated with faulting. The main type of data used comprised structural field data, well and resistivity data, remote sensing imagery, chronology of sediments, morphotectonic analysis, x-ray analysis, seismological and aeromagnetic data. Paleostress analysis indicates that at least two tectonic stress fields occurred in the study area: NSoriented compression and EW-oriented extension from the late Campanian to the early Miocene and EW-oriented compression and NS-oriented extension from the early Miocene to the Holocene. These stress fields reactivated NE-SW- and NW-SE-trending faults. Both set of faults exhibit right-lateral strike-slip kinematics, associated with a minor normal component. It was possible to determine the en echelon geometry of the Samambaia fault, which is ~63 km long, 13 km deep, presents NE-SW trend and strong dip to NW. Sedimentfilled faults in granite rocks yielded Optically Stimulated Luminescence (OSL) and Single-Aliquot Regeneration (SAR) ages at 8.000 - 9.000, 11.000 - 15.000, 16.000 - 24.000, 37.000 - 45.500, 53.609 - 67.959 e 83.000 - 84.000 yr BP. The analysis of the ductile fabric in the João Câmara area indicate that the regional foliation is NE-SW-oriented (032o - 042o), which coincides with the orientation of the epicenters and Si-rich veins. The collective evidence points to reactivation of preexisting structures. Paleoseismological data suggest paleoseismic activity much higher than the one indicated by the short historical and instrumental record

Turismo, território e políticas públicas: uma análise do destino João Pessoa/PB

This study presents an approach to tourism activity from the perspective of the territory, analyzing the importance of the roles of the State and public policies for tourism development. Tourism in the northeastern region of Brazil begins to take its rise from the late 1970 through public policies, whose goal was to provide the necessary conditions for tourism development. The tourism public policies were the key elements in the production process of tourist territories in the region. In the state of Paraíba, the public authorities elected the coastline as the main attraction and the state capital, João Pessoa, as the locus for the tourism development, with the city receiving a series of public policies. In this context, this research aims to analyze the development process of three specific public policies for tourism development in João Pessoa: The (mega)Projeto Costa do Sol (1988), the PRODETUR/PB I and II (1997 e 2005) and the Plano Estratégico de Desenvolvimento do Turismo na Paraíba, the Plano Amanhecer (2000). This study was guided by the question that even having been contemplated by the tourism public policies, João Pessoa still remains in a peripheral position in the regional tourism market. The methodological procedures for this study were literature and documents research and semi-structured interviews with tourism public officials and representatives from local tourism trade. The research came to prove that the discontinuity between governmental administrations hampered the implementation process of the tourism public policies studied. It was observed that the implementation of tourism public policies in the long term depends on the interaction between governments, as well as the collective political will to develop tourism in Joao Pessoa

O reassentamento dos refugiados colombianos e palestinos no estado do Rio Grande do Norte

Since the second semester of 2004, the first refugees guided by ACNUR arrived at Potiguar s territory. Then we follow closely, with other local actors, the implementation and development of this innovative action, namely the resettlement of those refugees in Rio Grande do Norte. To accomplish this, we consider the concepts of territory, dispossession, repossession and international migration. The state of Rio Grande do Norte is a pioneer in the Northeast, in this type of action, since, before this experience, just Rio Grande do Sul and São Paulo were engaged in this kind of action. Therefore, this paper analyzes the process of resettlement of refugees, fulfilled in Rio Grande do Norte, between 2004 and 2005. The research broaches the regards that resulted in departure of these refugees from their respective territories (Colombia and Palestine) as well as the characteristics and prospects of the areas that hosted the refugees (Natal, Lajes e Poço Branco). Finally, the work deals with the results achieved afield, through interviews and photographic record, near by refugees
