Uma odisséia em busca de Héstia: do turismo à hospitalidade pelos caminhos das representações sociais

This thesis is the result of a piece of research on hospitality social representations between tourism professionals and academics in the city of Natal. The reasearch s corner stone is the point of the view that the notion of hospitality, with all its theoretical and practical implications, is essential to the success of any tourist destination. Is there any relevance in the growing use of the word, almost as a synonym for tourism? How is this notion, first learned in the domestic context and then exercised in the contact with the city and especially with visitors, represented in the learning process for professional practice and in the exercise of professional tourist reception itself? In order to answer this question, initially we chose to study the concept of hospitality in their current academic view, with reference to the French school, which binds hospitality to the maussian perspective of donation, and other scholars of the current theme, with emphasis on the research performed in the program of Master of Hospitality at the Anhembi Morumbi University, whose philosophy imprints in the hospitality concept the same sense we want to give this study. Then we chose to analyze the notion of hospitality, by the Social Representations Theory, in light of Moscovici s methodology, as well as the analysis of the core of this concept among tourism professionals and students. It was found that hospitality is still a very diffuse reference to representations of these two groups and that academic education, if accepted both theoretical and practical implications of this research s starting point, will still have a long way to go. Cities such as Natal, "naturally" hospitable, according to its dwellers, where tourism is relevant to their economies, need (re)thinking and (re)organizing, continuously, their actions towards quality and performance of their professional training especially those concerned with receptive structure

Testicular structure and spermatogenesis of Amazonian freshwater cururu stingray Potamotrygon cf. histrix

The cururu stingray Potamotrygon cf. histrix, a new and endemic Amazonian freshwater species, presents appropriate characteristics for fish keeping and is exploited from its natural environment. The present study identified the testicular structure and spermatogenesis of this species. Gonads from adult male specimens were dissected, fixed and processed for histological analysis. The testes were of testicular/epigonial type. The presence of germinal papillae was observed in the upper portion of organ with primordial germ cells and Sertoli cell precursors. The testis was lobular with zonal organization and cystic gametogenesis, with the occurrence of spermatoblasts. The Sertoli cells underwent morphological modifications over the course of gamete formation. The spermatozoids had long heads and were spiraled on their own axis. Information on the reproductive biology will serve as basis for studies on the reproduction and phylogeny of this peculiar group of cartilaginous fish.

Fatores associados à efetividade da doação de órgãos e tecidos para transplantes

The transplantation of organs and tissues presents itself as an important therapeutic option, both from a medical standpoint, the social or economic. Thus, the identification of variables that can interfere in the effectiveness of organs and tissues donation for transplantation needs to be investigated adequately, because it stands before increasing index of chronic and degenerative diseases in the population, what makes the waiting list for transplantation grow disproportionately and patients come to death without the opportunity of realization the treatment due to a lack of donors. In this context, has defined as objective of this study evaluate the factors associated with the effectiveness of organs and tissues donation for transplantation. It is a evaluative research, quantitative, prospective, with longitudinal design, developed at Central of Catchment, Notification and organ donation for transplant, Organ Procurement Organization and in six accredited hospitals to collect and transplantation of organs and tissues, in Natal/RN, between august 2010 and february 2011, after the approval of the Research Ethics Committee, under No. 414/10 and CAAE 007.0.294.000-10. The probabilistic sample without replacement was composed of 65 potential donors. It was used as an instrument of data collection a structured script non-participant observation of checklist type. Data were analyzed using descriptive statistics and presented in tables, charts, graphs and figures. For this, was used Microsoft Excel 2007 and statistical program SPSS version 20.0. To check the level of significance was chosen by applying the chi-square test (χ2) and Mann Whitney and caselas for less than five, it is considered the Fisher exact test. It was adopted as the significance level p-value <0.05. Among the surveyed it was observed that most of the individuals were male (50,8%), in the age group 45 years (53,8%), mean age of 42,3 years, minimum 5 and maximum 73 years (± 17,32 years). Single / widowers / divorced (56,9%), with up to completed elementary school (60,0%) in the exercise of professional activity (86,2%), catholic (83,1%) and residents in metropolitan region of Natal (52,3%). Was obtained donation effectiveness of 27,7%. There was no statistical significance between structure and effectiveness of the donation, but were observed inadequacies in physical resources (36,9%), materials (30,8%), organizational structure (29,2%) and human resources (18,5%). In the process, the maintenance phase (p= 0.004), diagnosis of brain death (p= 0.032), family interview (p≤ 0.001) and documentation (p= 0.001) presented statistical significance with effectiveness. Thus, it is accepts the alternative hypothesis of the study, in which is evidenced that the adequacy of the factors related to structure and process is associated to effectiveness of organs and tissues donation for transplantation. In this way, the effectiveness of organ and tissue donation ends in an essential way the rapidity and accuracy with which the donation process is conducted, requiring appropriate structure, with appropriate physical and material resources and skilled human resources to optimize the reduction of time and the suffering of those waiting for an organ or tissue transplant queued in Brazil

Doação de órgãos: meu corpo, minha sociedade

A doação de órgãos é um problema de relevância social e científica, pois envolve as formas como a vida é perpetuada através do corpo de outra pessoa, especificamente por meio de seus órgãos. Quais são os fatores de resistência e de facilitação à doação de órgãos? Este artigo propõe um fator de resistência e um de facilitação. O primeiro, o narcisismo pelo próprio corpo; o segundo, o desejo de perpetuar-se a si mesmo e a vida.

Doadores de sangue: qualidade de vida e atendimento em hemocentro de Natal / RN

The context of blood donation in Brazil faces problems since the start of its operations in the 1940, in the beginning the biggest obstacle was obtain safe and qualified blood, and then, established criteria for donations, the barrier is the low number of suitable candidates for donation. This suitability is associated with the good health of those who goes to the services of blood banks and the return of the donor is often conditioned by the way care is given and perceived by the user. The quality of life, defined as a perception that a person has of her/his position in the world, can influence the health and emerges as a way to focus on the subjectivity in a context dominated by objective and practical exams; listen to the views about the received services increases the focus on the user and provides feedback to the institution, guiding and planning its future actions. The purpose of this study was to verify the quality of life in blood donors and their perceptions of care in a blood center in Natal/RN. This is a descriptive cross sectional study conducted with blood donors from Dalton Cunha Barbosa blood center. The used protocols were: a structures questionnaire with questions on sociodemographic and services perception data, and SF-36 quality of life instrument. The sociodemographic and SF-36 data ware analyzed using descriptive and inferential statistics, using the statistical package PASW 18.0; those related to treatment were submitted to thematic content analysis. The results revealed a sample mainly composed by men, married people, who attended high school and had already made previous donations, with the first two groups returning more often for donations. The scores of the SF-36 confirm the certificated of good health of the screens, beind high in all areas and featuring a healthy population; statistically significant differences were denoted between sexes, levels of education and marital status. The speeches about the service were mostly positive and had as main focus acess, agility, technical aspects and subjective feelings. The data regarding the Rio Grande do Norte blood donors profile confirmed some characteristics of the Brazilian ones, those data of the SF-36 were similar to those found in studies with healthy groups and the impressions about the care received show similarities with national and international studies about the attendance at blood banks

Desenvolvimento de um novo complexo macrocíclico do sistema cobalto cyclam

In this work were synthesized and studied the spectroscopic and electrochemical characteristics of the coordination compounds trans-[Co (cyclam)Cl2]Cl, trans- Na[Co(cyclam)(tios)2], trans-[Co(en)2Cl2]Cl and trans-Na[Co(en)2(tios)2], where tios = thiosulfate and en = ethylenediamine. The compounds were characterized by: Elemental Analysis (CHN), Absorption Spectroscopy in the Infrared (IR), Uv-Visible Absorption Spectroscopy, Luminescence Spectroscopy and Electrochemistry (cyclic voltammetry). Elemental Analysis (CHN) suggests the following structures for the complex: trans- [Co(cyclam)Cl2]Cl.6H2O and trans-Na[Co(cyclam)(tios)2].7H2O. The electrochemical analysis, when compared the cathodic potential (Ec) processes of the complexes trans- [Co(cyclam)Cl2]Cl and trans-[Co(en)2Cl2]Cl, indicated a more negative value (-655 mV) for the second complex, suggesting a greater electron donation to the metal center in this complex which can be attributed to a greater proximity of the nitrogen atoms of ethylenediamine in relation to metal-nitrogen cyclam. Due to the effect of setting macrocyclic ring to the metal center, the metal-nitrogen bound in the cyclam are not as close as the ethylenediamine, this fact became these two ligands different. Similar behavior is also observed for complexes in which the chlorides are replaced by thiosulfate ligand, trans-Na[Co(en)2(tios)2] (-640 mV) and trans-Na[Co(cyclam)(tios)2] (-376 mV). In absorption spectroscopy in the UV-visible, there is the band of charge transfer LMCT (ligand p d* the metal) in the trans-Na[Co(cyclam)(tios)2] (350 nm, p tios  d* Co3+) and in the trans-Na[Co(en)2(tios)2] (333 nm, p tios d* Co3+), that present higher wavelength compared to complex precursor trans- [Co(cyclam)Cl2]Cl (318 nm, pCl  d* Co3+), indicating a facility of electron density transfer for the metal in the complex with the thiosulfate ligand. The infrared analysis showed the coordination of the thiosulfate ligand to the metal by bands in the region (620-635 cm-1), features that prove the monodentate coordination via the sulfur atom. The νN-H bands of the complexes with ethylenediamine are (3283 and 3267 cm-1) and the complex with cyclam bands are (3213 and 3133 cm-1). The luminescence spectrum of the trans-Na[Co(cyclam)(tios)2] present charge transfer band at 397 nm and bands dd at 438, 450, 467, 481 and 492 nm.

Diretrizes para conservação da espécie Mimosa Caesalpiniifolia Benth., Macaíba-RN

About 40% of the earth is occupied by tropical and subtropical forests, including 42% of dry forests, where there is Caatinga Bioma, contemplating tree forests and shrubs, with xerophytic characteristics. Study and conservations of Caatinga biologic diversity is one of the greatest challenges of Brazilian science because those are, proportionally, the less studied among natural areas, with most of the scientific effort centered in very few points around the main cities in the area and also because it is the less protected natural Brazilian area. The environmental degradation is constantly increasing and has its rhythm accelerated by the men appropriation to meet or not their own needs. Therefore, species conservation should be based in three principles: the use of natural resources by present generation, waste prevention and use of the natural resources to benefit the majority of the citizens. Among the strategies to species conservation, we can mention the ex situ conservation , in which the conservation of genetic resources may be realized outside of the natural environment in which the species occur, and in situ conservation , or, in other words, in the places where the species occur. In ex situ conservation, the germplasm collections are maintained in the field and/or in laboratories (conservation chambers), and this mainly conserves intraspecific diversity (genetic variance), the ex situ collections are continuously enriched by collection activities, introduction and germplasm interchange; the in situ conservation preserving ecosystems and habitats, maintaining and recovering native population of species of interest. So, the objective of this paper is the search for strategies to the conservation of Mimosa caesalpiniifolia B. (sabiá) using instruments of environmental perception and plant biotechnology, as mechanisms of in situ and ex situ conservation. To environmental perception, were realized open, semi-structured and qualitative interviews. The questions included socioeconomic data and knowledge of Sabiá specie. To plant biotechnology, Sabiá seed collection were realized in different location to formation of a germplasm bank. The specie micropropagation was made from nodal segment of plants from the matrizeiro. About the knowledge of rural populations and the use of Sabiá plant, some preferences occurred from speeches that the plant possesses a firm wood, not attacked by termites, legalized for exploration by the Brazilian environmental organ (IBAMA), and is a native specie. This research found the rural population has knowledge about Sabiá specie and the natural resources are exhausting. The proposal that the rural community brought was the donation of the Sabiá specie seeding initiating on the rain season, in which the seeding would be plated between the lots, in individual plantations. To the formation of a matrix bank, plant biothecnology brought answers favorable to Sabiá specie seeding, with the formation of multiple shoots

Expression and imprinting of insulin-like growth factor II (IGF2) and H19 genes in uterine leiomyomas

Genomic imprinting is defined as a gamete of origin-specific epigenetic modification of DNA leading to differential gene expression in the zygote. Several imprinted genes have been identified and some of them are associated with tumor development. We investigated the expression and the imprinting status of IGF2 and H19 genes in 47 uterine leiomyomas. Using allelic transcription assay, we detected the expression of the IGF2 gene in 10 of a total of 15 informative cases. No loss of imprinting, as determined by the finding of biallelic expression, was detected in any case. The expression of H19 gene was detected in 10 of 20 informative cases and the imprinting pattern was also maintained in all of them. Our data suggest that alterations in IGF2 and H19 genes expression by loss of imprinting do not occur in uterine leiomyomas. (C) 1999 Academic Press.

Uma leitura geográfica da reforma agrária potiguar

It understands a study made concerning the main aspects of the Agrarian Reform and the Agricultural Nestings of the Rio Grande do Norte. For in such a way an inquiry became necessary initially on the origin of the Brazilian agrarian concentration passing for the donation of Sesmarias, Land Law, Statute of Land and Ith National Plan of the Agrarian Reformation, as well as of the Social Movements of fight for the land appeared since century XIX: Canudos, Contestado, Cangaço, Ligas Camponesas and MST. Drawing the fight for the land in the Rio Grande do Norte, we rescue the component elements of the first indications of the Agrarian Reform and formation of Agricultural Nestings in the State. In the attempt to unmask the current situation of the Settlements, we investigate some concerning aspects to the conditions of life of the seated ones, that it is marked by innumerable problems that go since the lack of water until the a precariousness of the infrastructure and presence of services, over all with relation to the education and health. For in such a way we work initially on the basis of diverse bibliographical readings, together data-collecting the official agencies and some directly involved entities with the Agrarian Reform in the RN. We utilized also the research of field in 27 Settlements of different Microregions of the State that consisted of the application of interviews together to the leaderships of these Settlements and application of forms with the seated families who resulted in a bigger knowledge concerning the reality of these areas that integrate the Politics of the Agrarian Reform

Caring for organ donors: the intensive care unit physicians' view

This study examined the meanings that the intensive care unit (ICU) physicians attribute to their practice when caring for brain-dead organ donors. It is a phenomenological study, a qualitative method that searches for describing and understanding the experiences lived. Data were collected through recorded individual interviews made with 10 ICU physicians who work in a university hospital in the interior of São Paulo, Brazil. Three categories emerged from data: (1) providing care for brain-dead organ donors; (2) relating to donors and their families; and (3) the ethical concerns and self-awareness of the physicians. There is consensus as to-many aspects: demand of technical qualification and excellence in practice; need of investing in technology of organ transplant; and donors seen as human beings and holders of human rights. Participants understand that family participation is decisive in the donation process, although interactions between the family members and the physicians are difficult because of the sensitive nature of the situation. The physicians often felt ill-prepared to openly discuss the topic of brain death and organ donation. Educational programs for physicians and family members may assist with this difficult process.

A doação de sangue sob a ótica de escolares: concepções e valores

Nesta pesquisa investigou-se o nível de informação, percepção, motivos e sentimentos de escolares sobre a doação de sangue. 145 escolares do pré, 2ª, 4ª séries com seis, oito e 10 anos de idade foram submetidos a provas piagetianas, responderam uma entrevista, se posicionaram frente a um dilema. Verificou-se pouca informação e informações errôneas sobre a doação. A escola foi a fonte de informação menos citada. A maioria dos entrevistados tanto na entrevista, como no dilema, justificou a doação de sangue como um ato solidário, permitindo supor que valores como generosidade podem ser adquiridos na fase pré-operatória. Discute-se o papel da escola nos programas de Educação em Saúde voltados a comportamentos que serão emitidos a longo prazo e que beneficiam a coletividade.

Factors affecting fertilisation and early embryo quality in single- and superovulated dairy cattle

Data on fertilisation and embryo quality in dairy cattle are presented and the main factors responsible for the low fertility of single-ovulating lactating cows and embryo yield in superovulated dairy cattle are highlighted. During the past 50 years, the fertility in high-producing lactating dairy cattle has decreased as milk production increased. Recent data show conception rates to first service to be approximately 32% in lactating cows, whereas in heifers it has remained above 50%. Fertilisation does not seem to be the principal factor responsible for the low fertility in single-ovulating cows, because it has remained above 80%. Conversely, early embryonic development is impaired in high-producing dairy cows, as observed by most embryonic losses occurring during the first week after fertilisation. However, in superovulated dairy cattle, although fertilisation failure is more pronounced, averaging approximately 45%, the percentage of fertilised embryos viable at 1 week is quite high (>70%). Among the multifactorial causes of low fertility in lactating dairy cows, high feed intake associated with low concentrations of circulating steroids may contribute substantially to reduced embryo quality. Fertilisation failure in superovulated cattle may be a consequence of inappropriate gamete transport due to hormonal imbalances.
