SUPORTE SOCIAL E QUALIDADE DE VIDA EM IDOSOS PARTICIPANTES DE UM PROGRAMA DE EDUCAÇÃO PERMANENTE

Este estudo objetivou identificar e descrever uma possível relação entre suporte social e qualidade de vida, em pessoas idosas participantes de um programa de educação permanente, o qual é promovido por órgão público em parceria com uma universidade, instalada em um dos municípios que integram a região do ABC Paulista, em São Paulo. A amostra consistiu de 106 idosos, com idade a partir de 60 anos, de ambos os sexos, e que efetivamente participam do referido programa. Para a coleta de dados, a amostra foi dividida em dois subgrupos, onde o primeiro grupo constou de 54 idosos que freqüentam o programa há menos de 1 ano, e o outro grupo foi formado por 52 idosos que freqüentam o programa há mais de 1 ano, com isso objetivamos identificar uma possível existência de diferentes percepções entre os grupos, das variáveis estudadas, em função do tempo de participação no programa, o que não foi confirmado, com os resultados apontando para uma homogeneidade entre os grupos, tanto nos aspectos socioeconômicos quanto nas percepções de suporte social e qualidade de vida, independente do tempo de participação no programa. Este estudo utilizou método descritivo exploratório, de caráter quantitativo e comparativo. Para a coleta de dados foram utilizadas a Escala de Percepção de Suporte Social (EPSS), que avalia percepção de suporte social em suas dimensões emocional e prático; o instrumento de avaliação da qualidade de vida: WHOQOL Bref e Old, e um questionário com dados socioeconômicos que auxiliaram na caracterização do perfil da amostra e na análise estatística dos resultados. Os resultados apontaram que a amostra pesquisada caracteriza-se por possuir um perfil socioeconômico diferenciado, no que se refere a uma maior escolaridade e rendimento mensal, quando comparado a media nacional que mostra o perfil do idoso brasileiro mais vulnerável, com baixa escolaridade e rendimento. Os resultados das avaliações das percepções de suporte social e da qualidade de vida demonstraram tratar-se de idosos que se sentem satisfeitos com seu momento de vida; que percebem apoio emocional, sentindo-se objeto de afeto em sua rede social. Com relação a percepção de suporte prático, os resultados demonstraram que os idosos possuem uma percepção relativa, apontando dúvidas e incertezas quanto ao recebimento deste tipo de apoio de sua rede social. Diante deste resultado, percepção de dúvidas e incertezas em receber suporte prático, e a característica socioeconômica diferenciada da amostra, podemos supor que esses idosos possuem estas percepções, por se sentirem ou por serem de fato provedores e não dependentes da sua rede social. Não foi evidenciada correlação entre as variáveis suporte social e qualidade de vida, sugerindo que o construto suporte social talvez seja percebido pelos idosos da amostra como fator de diminuição da funcionalidade biopsicossocial ou da competência comportamental; ou ainda, pode-se supor que diante dos sentimentos de satisfação com a vida atual, a amostra de idosos volta-se menos aos aspectos protetores do suporte social.

RELAXAMENTO PSICOFÍSICO EM CRIANÇAS

Trabalho de natureza monográfica bibliográfica investiga o relaxamento psicofísico na área da saúde, em crianças, por um intervalo de oito anos, entre janeiro de 1997 e novembro de 2004. Inicialmente, com base em literatura neuropsicológica, descreve o papel do relaxamento na busca da homeostase e da consciência corporal saudável, enfocando comportamentos de prazer e dor. A seguir, descreve e analisa diversas técnicas de relaxamento, Relaxamento Progressivo de Jacobson, Autógeno de Schultz e Relaxamento de Michaux. A fim de desenvolver sua pesquisa utiliza-se de 27 bases de dados, devido a pouca produção encontrada sobre o tema, por base. Como resultados, levanta ao todo 500 artigos sobre relaxamento, sendo 200 em crianças. São artigos nacionais e internacionais, com predomínio do idioma inglês. A seguir, classifica esses artigos por ano de produção, constatando um crescimento significativo, porém não sistemático em seu número, de 14 artigos em 1997, para 39, em 2004. Quanto à temática, os dados revelam em primeiro lugar, um interesse em dor, em segundo em problemas respiratórios, e, em terceiro lugar, em ansiedade. Os artigos sobre dor, por serem os mais numerosos levantados, sofrem análise mais detalhada, com discriminação da quantidade de artigos por ano e dos tipos de situação e de patologia caracterizados por quadro álgico. Finalmente é feita uma classificação dos artigos segundo a utilização do relaxamento junto à problemática clínica predominantemente física, a de fundo psíquico afetivo-emocional, sem utilização de fármacos e, a de fundo psíquico, com intervenção psiquiátrica farmacológica. Na discussão dos resultados, vários artigos pesquisados são também comentados. Dada a riqueza dos dados, evidenciando interesse crescente de profissionais da área da Saúde na literatura levantada, sugere-se pesquisa complementar.

“A relevância na organização do líder empreendedor”

O empreendedorismo é um conceito cada vez mais presente nas organizações empresariais ou nos sistemas educacionais, assumindo um destaque incremental no debate público no que concerne ao futuro das políticas económicas para a competitividade, no âmbito da economia do conhecimento e da sociedade da informação. A sua pertinência instigou o seu estudo nas suas diferentes valências, agudizada pela crise estrutural do capital. Este trabalho visa a análise do conceito empreendedorismo, assente na caracterização do perfil comportamental do empreendedor e na identificação do seu papel nas organizações. Anui-se uma relação estreita entre o conceito de empreender e a descoberta profícua de oportunidades, que se fundeiam num espírito de mudança e inovação, central ao empreendedor. A competitividade afigura-se como uma premissa basilar na criação de valor e no progresso sustentável das organizações. O desafio consiste na mudança de paradigmas ao nível de: i) modelos de desenvolvimento, pela valoração do conhecimento e tecnologia em detrimento da dependência de recursos físicos e financeiros; e ii) fomentação da audácia e consolidação de uma cultura em inovação, competitividade e mudança. A intrínseca aliança do empreendedorismo-inovação assevera-se como fator crítico de desenvolvimento, dependente do perfil comportamental do indivíduo, líder, empreendedor. Essa dependência não imiscui a preponderância da formação para o empreendedorismo, que deve instigar e promover as competências vitais à criação inovadora e sustentável de novos empreendimentos. O estudo desenvolvido no âmbito do empreendedorismo permite asseverar uma dissimilitude de conceitos e aceções, alicerçados em evidências empíricas e científicas ainda exíguas. O trabalho perscrutado objetiva primordialmente uma maior sensibilização das comunidades organizacionais e académicas a esta temática que permita contribuir para uma compreensão mais abrangente e atual da sua relevância no seio das organizações, que vivenciam uma mudança de paradigma nas suas múltiplas dimensões. Esta mudança de paradigma insurge-se num contexto situacional económico-financeiro estrutural e globalmente debilitado, em que se assevera a premência do progresso sustentável das organizações aliada à pertinência do fator diferenciação, que se traduzem por uma transfiguração dos conceitos e padrões observados até aqui. O empreendedorismo assume uma capital importância, salientando-se a perspetiva comportamental do líder empreendedor no processo eficaz de criação de valor: incremental, diferenciador e sustentável. O comportamento organizacional deve assumir uma preponderância central na gestão empreendedora das organizações, ao nível dos seus agentes determinantes: condições (cultura, liderança, estratégia), recursos (capital humano, competências, relacionamentos externos, estruturas), processos (gestão de atividades de IDI, aprendizagem e melhoria sistemática, proteção e valorização de resultados) e resultados (financeiros e operacionais, mercado e sociedade). A análise privilegiadamente comportamental que instigue a diferenciação como fator de inovação e criação de valor nas organizações atuais é corroborada por um estudo de caso que visa a elaboração de um modelo estrutural conceptual e um modelo de correlações canónicas de empresas do ramo automóvel, em Portugal, concelho de Vila Nova de Famalicão, que: 1. Tendeu a observar: i) a tipificação e influência do perfil de empreendedor deste concelho e ramo de atividade nas múltiplas dimensões do empreendedorismo sustentável – desempenho organizacional, inibidores e aceleradores da atividade empreendedora e relevância do papel do líder empreendedor; e ii) a construção de um modelo estrutural conceptual e de um modelo de correlações canónicas que conduziu a quatro tipologias de empreendedor e a sua envolvente; 2. Intentou a ilustração de uma pertinência empírica futura para o seu desenvolvimento e aplicabilidade nas organizações.

Densidade de estocagem em camarões da espécie Macrobrachium rosenbergii (De Man, 1879) na fase juvenil

Among the species of freshwater shrimp being cultivated, Macrobrachium rosenbergii stands out. Knowledge about the behavior of this species and the influence of certain factors on its development can help optimize management practices and minimize the likely impacts shrimp farming has on the environment and the animals themselves. The objective of this study was to characterize the species' behavior during early stages of development under different stocking densities over a 24-hour cycle. Ten day old postlarvae were transferred from the Jundiaí School of Agriculture (EAJ - Escola Agrícola de Jundiaí) in Macaíba (RN), Brazil to the Shrimp Behavior Laboratory (LSPR - Laboratório de Estudos do Comportamento do Camarão) at the Federal University of Rio Grande do Norte (UFRN), where they were weighed and measured. Eight aquaria with constant temperature, aeration and filtration, and subjected to a12 h light/12 h dark cycle were used for each experiment. Each aquarium also contained two shelters made of bricks and the water quality was monitored weekly. Behavioral observations were made at two densities: 25 individuals/m-² and 40 individuals/m-². The methods for recording behaviors were: behavioral sampling – enter and leave the shelter, exploring on the substrate, exploring in the water column, move away, attack, pursuit and cannibalism; scan sampling - inactivity, feeding, exploration, digging, swimming, cleaning and staying in the shelter. Observations were made during a 15 minute period/per aquarium at a frequency of 4 times daily, for 4 days/week, and over 4 weeks. Food was provided 2 times/day for each aquarium population, immediately before the 1st and 3rd observation periods. Our results demonstrate that at high density, there is an increased frequency of agonistic behavior; during the light phase, there is a greater frequency of behaviors that result in less exposure (inactivity, cleaning and staying in the shelter); during the dark phase, there is an increased frequency of behaviors that result in greater exposure (feeding, exploration, swimming and digging); at times of feed offer, there is an increased frequency of leaving the shelter, moving away, pursuit, feeding, exploration and swimming. At low density, the animals showed a lower frequency of agonistic behaviors, greater weight gain and higher growth rates, which indicates that this is a more favorable growing environment for cultivation and when applied, can generate better living conditions, favor survival rates and increase management success

Influência do tipo de abrigo e da frequência de oferta alimentar no comportamento do camarão Macrobrachium rosenbergii (De Man 1879)

Macrobrachium rosenbergii is a freshwater prawn which presents agonistic behavior and heterogeneous growth. It is known that captive conditions can intensify agonism causing injuries and decreased survival, generating a condition of poor welfare. Based on this, we aim to investigate the behavior of M. rosenbergii in the juvenile phase according to different types of shelter and frequencies of feed offer, emphasizing their agonistic behavior. For this, juveniles were observed in the laboratory in three steps. At step I we characterized the behavioral profile; prawns were kept in eight aquariums (27 prawns/m2 ), identified and observed four times along both phases of 24 h light cycle. At step II (2 experiments), we evaluated the use of shelters (brick or polyethylene rolls) and their influence on agonism by the animals. For classification of animals in dominance rank, the method used was David's Score. At step III (3 experiments), we evaluated different frequencies of feed offer on the behavior of individuals, in particular agonism. Results showed that juveniles do not present a pattern activity/inactivity between the phases of the light cycle. We identified a dominance hierarchy among individuals taking advantage of access to food by the dominant, which showed greater weight gain although the frequency of intake did not differ between individuals. The type of shelter influenced the behavior of animals. Brick shelter generated a higher frequency of permanence and a reduction in the frequency of agonistic interactions. The distribution of food more frequently throughout the day, decreased the motivation of animals for food, as well as to fight. Prawns fed four times showed lower frequency of feed intake and agonistic interactions. Thus, we conclude the shelters which reduce animal’s detection by coespecifics and offer the food four times along the day reduce agonistic behavior. This result causes na improvement in life quality of the prawns and also in its quality as final product.

Contribuições ao estudo de modelagem de equações estruturais na avaliação da satisfação do cliente de serviços de comunicações móveis

No mercado de telecomunicações as transformações tecnológicas das últimas décadas aliaram-se a um cenário formado por empresas de alta tecnologia que caracterizam o setor de comunicações móveis pessoais em todo mundo. Neste contexto, as empresas deste setor preocupam-se cada vez mais com a competitividade, oferta de serviços, área de atendimento, demanda reprimida e a lealdade do cliente. Estudos de comportamento do consumidor pesquisam a satisfação e lealdade de clientes como fatores básicos para relações bem sucedidas e duradouras com as empresas. A complexidade das relações entre variáveis na avaliação da satisfação do cliente em comunicações móveis pode ser adequadamente pesquisada com a utilização de métodos estatísticos multivariados. Essa tese analisou as relações causais envolvendo os antecedentes e consequentes associados à satisfação do cliente, no segmento de comunicações móveis, bem como desenvolveu e validou um modelo comportamental do cliente no uso deste serviço, buscando explicar as relações entre os construtos envolvidos: satisfação, qualidade dos serviços, valor percebido, imagem da marca, lealdade e reclamação. Foi estabelecida uma ampla base teórica para avaliar a importância estratégica do modelo que relaciona a influência na satisfação do serviço com as percepções dos clientes e avaliada a precisão deste modelo, por meio de uma análise comparativa a utilização de três métodos de estimação dos seus parâmetros, MLE, GLS, e ULS, com o emprego de modelagem de equações estruturais. Foram feitas aplicações em análises de dados, sendo testada e avaliada empiricamente, a influência do gênero na satisfação do cliente deste setor, além de uma segmentação de mercado utilizando mapas auto-organizáveis e a correspondente validação deste processo, com modelagem de equações estruturais.Os resultados do estudo empírico produziram uma boa qualidade de ajustamento para o modelo teórico proposto, com evidências do estabelecimento de uma adequada capacidade explicativa e preditiva, destacando-se a relevância da relação causal entre a satisfação e lealdade, em consonância com diversos estudos realizados para os mercados de comunicações móveis.

Decisões comportamentais em contexto de forrageamento de dinoponera quadriceps

The behavioral decisions of animals do not occur randomly, because behaviors are adjusted to ensure the survival and reproduction of the animal. In this research, I examined behavioral decisions in the foraging context of the ant Dinoponera quadriceps with regard to orientation, food avaliation and foraging dynamic to individual level. The study was conducted at the Laboratory of Behavioral Biology at UFRN and in an area of secondary Atlantic Forest in FLONA-ICMBio Nísia Floresta/RN. In all observations and experiments, ants were marked individually with an alphanumeric code label fixed on the thorax. In the first part of the study, I analyzed the orientation cues used by D. quadriceps. The tests were performed in a maze of 17 compartments. Each forager was tested for 10 min in three sessions for six different treatments. The treatments consisted of the presence or absence of odor and superior or frontal visual cues. The workers demonstrated that the presence of odor is indispensable and front visual cues are more effective than superior visual cues. In the second part, I investigated the discrimination of food, considering the parameters, size, weight and volume. In a 'cafeteria' experiment, I offered cylindrical pieces of food (mortadella) in a Petri dish, within an experimental arena 1m². Initially, the pieces were of four different sizes; in a second step, the pieces were of the same size but with different weight; in the last step, the pieces had the same weight but different volumes. The results showed the effect of the size and weight parameters for food choice. In the third part of the study, I evaluated the influence of the activity of active foragers on inactive ones. In this part, the colonies were observed in a natural environment. The observations took place on three consecutive days in 10 episodes, total of 30 days for each colony, 12 hours/day. On the first day, I registered the output and input of workers; on the second day, the most active ants on the first day were taken and given back at the end of the observations; on the third day, the observations were similar to the first day. As a result, the workers of D. quadriceps show autostimulation and they do not show social facilitation and the colony compensates the absence of the most active workers. Based on the stated, I conclude that workers of D. quadriceps use chemical, frontal and superior visual orientation cues during their displacements. They discriminate the chosen food by size and weight. The regulation of activity dynamics of foragers is by autostimulation, an active worker does not influence the activity of an inactive worker, the successful search previous is the stimulus to the successful worker itself to continue foraging activity.

Análise textual das representações discursivas no discurso político brasileiro: o discurso da primeira posse da presidenta Dilma Rousseff (1°/01/2011)

Cette recherche décrit la représentation discursive que la présidente Dilma Rousseff fait de soi-même, dans son discours devant le Congrès National, lors de la journée d’investiture, le 1/1/2011. Notre travail se situe dans le domaine théorique et méthodologique de la linguistique du texte et, plus spécialement, dans la perspective de l’Analyse Textuelle des Discours – ATD (ADAM, 2011 [2008a]), qui se définit comme « une théorie de la production co(n)textuelle de sens qui doit se fonder sur l’analyse de textes concrets ». Elle nous fournit la notion théorique et analytique de « représentation discursive », qui se focalise sur la dimension sémantique du texte. Nous nous appuyons, aussi, sur des travaux récents sur les représentations discursives, réalisés dans la recherche brésilienne sur l’ATD (RODRIGUES, PASSEGGI, SILVA NETO, 2010, 2012; RAMOS, 2011; OLIVEIRA, 2013; QUEIROZ, 2013; ZAMBLANO-OLIVEIRA, PASSEGGI, 2013). Les principales opérations sémantiques de construction de la représentation discursive utilisées dans notre travail sont la Référenciation et la Prédication. L’approche méthodologique est, en même temps, qualitative et quantitative, priorisant l’identification des occurrences, ainsi que la description détaillée de leurs valeurs sémantiques et textuelles. Les résultats de la recherche sont de trois ordres : méthodologique, théorique et descriptif-interprétatif. Méthodologique : nous proposons une approche que nous désignons comme « marquage textuel » (ou « mappage textuel ») qui permet de marquer (étiqueter) les valeurs sémantiques des formes linguistiques, permettant leur identification dans le flux textuel, c.-à-d., dans la dimension séquentiellecompositionnelle du texte. Théorique : nous introduisons la notion de « domaines de la représentation discursive » qui organisent et articulent les différents éléments qui composent la représentation discursive de la présidente. Quant aux résultats descriptifsinterprétatifs du discours de l’investiture, ils indiquent que la représentation discursive de la présidente se configure au moyen de différents domaines conceptuels, explicités par les référenciations et les prédications. Ils mettent en relief les désignations et les actions / états, aussi bien de la femme – domaine du genre – que de la présidente – domaine du rôle politique et institutionnel. La présidente se représente explicitement et avec emphase comme l’agent responsable par les actions exprimées par les prédications verbales (verbes d’action), consciente de l’importance de son rôle politique et social. Les prédications nominales signalent clairement une représentation discursive qui englobe les domaines conceptuels politique, moral, éthique, comportemental et émotionnel (forte, accueillante, pionnière, consolidatrice, infatigable, humble, engagée, démocrate, victorieuse et courageuse). Le discours d’investiture réalise, donc, des désignations positives de la présidente, lesquelles se situent dans un temps présent et prospectif – avec des perspectives de futur – comme leader politique du Brésil, avec une participation active dans la transformation du pays, tenant compte aussi de son histoire de vie, sa biographie de luttes. Ainsi, la description empirique et l’interprétation de ce discours particulier contribue à l’analyse textuelle des représentations discursives dans le discours politique brésilien contemporain. Elle soulève, aussi, des questions théoriques et méthodologiques qui nous semblent pertinentes pour le développement de cette aproche.

Herpetofauna associada à bromélia rupícola, encholirium spectabile, no semiárido brasileiro: revisão da literatura, ecologia das espécies e comportamento de psychosaura agmosticha (squamata: mabuyidae)

Bromeliads are an important microhabitat for the herpetofauna, for being widely used as refuge from predators and their leaf architecture allows humidity maintenance and relatively constant temperature inside, setting a favorable environment for amphibians and reptiles, especially in areas under hydric stress. However, studies addressing this relationship are still incipient and more concentrated in fitotelmatas bromeliad. For non-fitotelmatas rupicolous bromeliads of the gender Encholirium, which develops into rocky outcrops and contains species of semi-arid regions such as the Caatinga, animal-plant relationships are almost unknown. In this context, this study aimed to know the herpetological fauna inhabitant of macambiras bromeliads, Encholirium spectabile, analyzing occupation and use of these bromeliads by different taxa, and the behavioral ecology of the lizard Psychosaura agmosticha, seeking to identify factors associated with this strict relationship in Caatinga. An extensive review of the world literature on the subject “lizards in bromeliads” subsidized this study from the ecological perspective of this association. The field work was carried out at Fazenda Tanques, municipality of Santa Maria / RN, mesoregion of Agreste Potiguar. The observations and/or data collection in daytime and in the evening was conducted monthly during three consecutive days, from January 2011 to August 2012, totaling 450 hour.man of sampling effort. Sixteen species were registered: six lizards (Mabuyidae, Tropiduridae, Gekkonidae and Phyllodactylidae Families), six snakes (Boidae and Dipsadidae Families) and four of amphibians of Hylidae Family. The effect of the forest edge on the distribution of species along the outcrop was significant, with most species found in outcrop edges. Significant difference was found between some pairs of species concerning use of bromeliads, and almost total niche overlap in the use of microhabitat. 62.5% of the species are nocturnal and use these plants for sheltering, breeding and feeding. Regarding the relations between 4 the lizard Psychosaura agmosticha and macambiras bromeliads, behaviors of thermoregulation and foraging in the dry and wet seasons were recorded. Activity periods were concentrated between 7 and 10 am and between 3 and 5 pm in both seasons, showing a clear bimodal pattern. The species basically used the green leaves and there were no significant differences between males and females in the use of bromeliads. Positive associations were found between body temperature and temperatures of bromeliads and air. This species spent 1.95% ± 3.8 of the time moving (PTM) and moved on average 0:36 ± 2.1 seconds per minute (MPM), with significant differences between the wet and dry to PTM, and between the average time of stop and average duration of movements, being considered a sedentary forager. Psychosaura agmosticha, in the study area, is bromelicolous and uses macambiras primarily for thermoregulation and foraging. The results of this study elevate the rupicolous bromeliads Encholirium spectabile as key elements for the maintenance of amphibians and reptiles associated with it, and a clear advantageous association for the conservation of the groups involved.

Avaliação dos efeitos da retirada do etanol em curto e longo prazo sobre respostas comportamentais relacionadas à ansiedade e sobre células imunorreativas para a serotonina no núcleo dorsal da Rafe em ratas

Ethanol withdrawn individuals present a wealth of signs and symptoms, some of them related with anxiety. To better understand brain areas involved in anxiety caused by ethanol abstinence, preclinical studies have been employing models of ethanol consumption followed by withdrawal in rodents submitted to behavioral tests of anxiety, such as the elevated plus-maze. The aim of this study was to investigate if short- or long-term ethanol withdrawal could alter both anxiety-related behaviors in the elevated plus-maze (EPM) and open field tests and the number of serotonin immunorreactive cels in the dorsal raphe nucleus, a midbrain area associated with anxiety. Female Wistar rats (90 days old) were submitted to increasing concentrations of ethanol (2% for 3 days, 4% for 3 days and 6% for 15 days) as the only source of liquid diet and the control group received water ad libitum. Both groups received food ad libitum. In the behavioral experiments, on 21st day of consumption, ethanol was substituted by water (withdrawal) and 72 h or 21 days after withdrawal animals were submitted to the EPM, where it was evaluated the percentage of time and entries in the open arms and the entries in the enclosed arms during 5 minutes. Twenty and four hours after testing in the EPM, animals were submitted to the open field test for 15 minutes, where the distance traveled by the animals was observed along this period. During the first 5 minutes, the distance traveled, entries and time spent in the center of the test were analyzed. In the immunohistochemistry study, animals were submitted to 21 days of consumption of ethanol followed or not by 72 hours and 21 days of withdrawal previously perfusion, brain tissue preparation and quantification of serotonin dyed cells in the dorsal and caudal portions in the dorsal raphe nucleus. Behavioral data showed that both short- and long-term ethanol withdrawals reduced the open arms exploration in the EPM. In the open field test there were no locomotor activity changes during the total 15 minutes; however, longterm ethanol withdrawal reduced the exploration in the center of the open field during the first 5 minutes. In the immunohistochemistry step, there were no differences, when short- and long-term withdrawn groups were compared with control group; nevertheless, the chronic consumption of ethanol decreased the number of serotonergic immunorreactive cells in the dorsal part of dorsal raphe nucleus. Taken together, results here obtained suggest that both short- and long-term ethanol withdrawals promoted an anxiogenic-like effect that was not related with changes in the serotonin immunorreactivity in the dorsal and caudal parts of the dorsal raphe nucleus.

Representações sociais de familiares sobre o atendimento das emergências psiquiátricas

The reformist movements in the field of mental health have pointed battle flags, among which the prioritization of production of mental health care out of the asylum environment should be highlighted, aiming the reduction of psychiatric beds, greater control over the hospitalization, family co-participation and the rescue of the citizenship of the social players involved. With the progressive reduction of asylum beds, associated with a lot of structural problems in the health services, the occurrence of crises outside the hospital environment has been increasingly frequent, thus giving the family an important therapeutic role. In face of this scenario, there is an urgent need to understand the social construction of the care for psychiatric emergencies, identifying the meanings assigned by family members to their constituent aspects. This study seeks to answer the following research question: what are the social representations of family members about the care of psychiatric emergencies in the city of Mossoró, Rio Grande do Norte? Therefore, the aim is to analyze the social representations of family members about the care of psychiatric emergencies in the city of Mossoró, Rio Grande do Norte. This is an exploratory and descriptive study, with a mixed approach, making use of multimethods: for collection, the semi-structured interview and the Technique of Free Association of Words; for data analysis, the Thematic Analysis of Bardin and its steps was used, with the informational support of the softwares ALCESTE (Analyse Lexicale par Contexte d'un Ensemble de Segments de Texte) and Iramuteq (Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires); and the theoretical support of social representations. The study participants totaled 72, and they were selected from the following criteria: older than18 years, with degree of kinship with users suffering from some mental and behavioral disorder, and who have already witnessed a situation of crisis, rescued by the SAMU or other means and taken to the psychiatric hospital or general emergency room. Preliminary results point out: 1.Previous note of the research project with the aim to disseminate it in the scientific community and ensure the intellectual property of the work; 2.The contextual analysis of the care for emergencies in the study place. Reflection about the phenomenon provide a name to the care for the psychiatric emergencies, which is called immediate context; the technical and operational aspects that influence the care, as a specific/ general context; and mental health policies in Brazil are identified as metacontext; 3. The systematic review from randomized clinical trials in the databases PubMed, COCHRANE, LILACS, SciELO and SCIRUS, with the use of the descriptors: ‘Physical restraint’, ‘Psychiatric emergency services’, ‘Restraint’, ‘Physical and Emergency Services’, ‘Psychiatric’. Only one work met the search protocol criteria: a short-term essay that records limited results about the proportion of people who are in restraint and seclusion. It does not show statistically significant results in relation to indications, contraindications and risks of the use of physical restraint; 4. The social representations of the care for psychiatric emergencies. The study results point to the presence of five thematic categories: 1. feeling in the face of the crisis/care; 2. thoughts and perspectives about the crisis/care; 3. centrality of care in the medical- medication-hospitalization triad; 4. the thinking/acting in the face of the use of physical restraint and police force; 5. periodicity of crises. The central core of the representation is in the first category, whilst the peripheral elements are in the third and fifth categories. The contrast zone is in the second and fourth categories. The sadness is the most prominent element of the structure. The social representations about the care for psychiatric crises are at a time of transition between the hegemonic and reformist models, with the traditional aspects being predominant, but already showing peripheral and contrast elements that point to a possible change in the representational field.

Uma reflexão sobre a vitalidade urbana das praças de Natal/RN

Squares are urban public open spaces whose use combines a number of elements that can provide their vitality, some of which can be enhanced through strategic projects. Given this general framework, the starting question which triggered this thesis: Would the elements that the literature indicate influence the vitality of the squares be perceived by their users? The hypothesis put forward was that users give priority to elements directly involved in the appropriation of space, especially the furniture and existing equipment, levels of shade and security. The focus of empirical research were public squares located in the city of Natal-RN, with the aim to identify elements that contribute to the vitality of the public squares in the city, through the relationship between spatial morphology and environmental awareness. The methodology adopted was a Case Study conducted by multimethod, using the following procedures: morphological analysis based on literature and information at three levels (radius of influence, 500m; immediate surroundings; environment itself); systematic observation (behavioral mapping centred in the location); and semi-structured interviews with users. The results showed that the public spaces more integrated in the urban areas have greater potential for use, however, its effective use depends on the perception of individuals, so that its vitality is mainly due to items identified by users as central to their continued presence in the environment because they directly affect their wellbeing and the image of the location. So some elements, notably furniture and urban equipment, are more easily detected than others, revealing that they are essential to the perception of users, so that their presence, quality and location appeared to have greater impact on use. In addition, the amount of shade and security showed as items that ensure that individuals experience public spaces more often, since the (likely) users are aware of the conservation actions or abandonment that take place on these sites, revealing itself to be potentially involved in the rescue of these spaces. Overall, the general hypothesis is only partially proven because in many situations, the vitality of squares appeared not only to be related to the elements investigated, but also additional aspects - environmental, nature, economic, social and cultural - which should also be studied.

Caracterização citoarquitetônica e por imunoistoquímica para tirosina-hidroxilase da substância negra, área tegmentar ventral e zona retrorubral do Sagui (Callithrix jacchus)

It is known that the catecholamine group is constituted by dopamine, noradrenaline and adrenaline, in which the synthesis is regulated by an enzyme named tyrosine hydroxylase. Thus, 3-hydroxytyramine/dopamine (DA) is a precursor of the noradrenaline and adrenaline synthesis and acts as a neurotransmitter in the central nervous system. The three main nuclei, named the retrorubral field (A8 group), the substantia nigra pars compacta (A9 group) and the ventral tegmental area (A10 group), are arranged in the die-mesencephalic portion and are involved in three complexes circuitries - the mesostriatal, mesolimbic and mesocortical pathways. These pathways are related to behavioral manifestations, motricity, learning, reward and pathologies such as Parkinson’s Disease and Schizophrenia. Thus, the aim of this study was to perform de morphological analysis of the A8, A9 and A10 nuclei of the common marmoset (Callithrix jacchus). The marmoset is a neotropical primate, whose morphological and functional characteristics supports the suitability of use of this animal in biomedical research. Coronal sections of the marmoset brain were submitted to cytoarchitectonic characterization and TH-immunohistochemistry. Based on the morphology of the neurons, it was possible to subdivide the A10 group in seven regions: interfascicular nucleus, raphe rostral linear nucleus and raphe caudal linear nucleus, in the middle line; paranigral and parainterfascicular nucleus, in the middle zone; rostral portion of the ventral tegmental area nucleus and parabrachial pigmented nucleus, located in the dorsolateral portion of the mesencephalic tegmentum. A9 group was divided into four regions: substantia nigra compacta dorsal and ventral tiers; substantia nigra compacta lateral and medial clusters. No subdivisions were founded into A8 group. These results revealed that A8, A9 and A10 are phylogenetically conserved between species, but it’s necessary to expand the studies about this compartmentalization, investigating its occurrence in other primate species or investigating its functional relevance.

Citoarquitetura e imunoistoquímica para tirosinahidroxilase dos núcleos dopaminérgicos mesencefálicos do morcego (Artibeus planirostris)

The 3-Hidroxytyramine/dopamine (DA) is a monoamine of catecholamine family and isthe precursor substance synthesis of noradrenaline and adrenaline, having the enzymeTyrosine Hydroxylase (TH) as this regulatory process. In addition, the DA has theability to act as a neurotransmitter in the Central Nervous System - SNC, being themain neurotransmitter of brain nuclei, namely of A8 to A16. The nuclei of the midbrainthat express DA are the Retrorubral Field (RRF, A8), the Substantia Nigra parsCompacta (SNc, A9) and the Ventral Tegmental Area (VTA, A10). Such nuclei areinvolved in complex three circuitry that are the mesostriatal, mesolimbic andmesocotical and are directly related with several behavioral manifestations as motricitycontrol, reward signaling in behavioral learning, motivation and pathologicalconditions, such as Parkinson's Disease and schizophrenia. Interestingly, many of themorphological bases of these neural disturbance remain unknown. Considering therelevance of mesencephalic dopaminergic nuclei, the aim of this research is tocharacterize morphologically the dopaminergic nuclei (clusters A8, A9 and A10) of themidbrain of the bat (Artibeus planirostris). The Artibeus planirostris is a common bat inRio Grande do Norte. Ten animals were used in this research. The animals wereanesthetized, perfused, and the brain was removed from the skull. After dehydration insucrose, the brain was underwent microtomy. Saggital and coronal sections wereobtained and collected in six separate series. The series were Nissl-stained to identifythe cytoarchitectonic boundaries and the other series were subjected toimmunohistochemistry for TH. After cytoarchitectonic analysis and TH+ cellsidentification was possible to establish the anatomical boundaries of the nuclei, as wellas the subdivisions of three of the midbrain dopaminergic nuclei. The SNc is the mostrostral nucleus observed in the midbrain and is identified throughout the rostrocaudalextension of the midbrain. The VTA neurons were seen immediately caudal to the SNcappearance. The RRF neurons were observed just in the caudal levels of the midbrain.The SNc in Artibeus planirostris shows a particular feature, the tail of the SNc. The tailhave been described just in two other studied species. The present work shows aparticular variation in the organizational morphology of the SNc in the artibeus andcontribute to understand the phylogenetic routes by which the dopaminergic system hasevolved.

Behavioural profiles of captive capuchin monkeys (Sapajus spp.): analyses at group and individual levels

The use of behavioural indicators of suffering and welfare in captive animals has produced ambiguous results. In comparisons between groups, those in worse condition tend to exhibit increased overall rate of Behaviours Potentially Indicative of Stress (BPIS), but when comparing within groups, individuals differ in their stress coping strategies. This dissertation presents analyses to unravel the Behavioural Profile of a sample of 26 captive capuchin monkeys, of three different species (Sapajus libidinosus, S. flavius and S. xanthosternos), kept in different enclosure types. In total, 147,17 hours of data were collected. We explored four type of analysis: Activity Budgets, Diversity indexes, Markov chains and Sequence analyses, and Social Network Analyses, resulting in nine indexes of behavioural occurrence and organization. In chapter One we explore group differences. Results support predictions of minor sex and species differences and major differences in behavioural profile due to enclosure type: i. individuals in less enriched enclosures exhibited a more diverse BPIS repertoire and a decreased probability of a sequence with six Genus Normative Behaviour; ii. number of most probable behavioural transitions including at least one BPIS was higher in less enriched enclosures; iii. proeminence indexes indicate that BPIS function as dead ends of behavioural sequences, and proeminence of three BPIS (pacing, self-direct, active I) were higher in less enriched enclosures. Overall, these data are not supportive of BPIS as a repetitive pattern, with a mantra-like calming effect. Rather, the picture that emerges is more supportive of BPIS as activities that disrupt organization of behaviours, introducing “noise” that compromises optimal activity budget. In chapter Two we explored individual differences in stress coping strategies. We classified individuals along six axes of exploratory behaviour. These were only weakly correlated indicating low correlation among behavioural indicators of syndromes. Nevertheless, the results are suggestive of two broad stress coping strategies, similar to the bold/proactive and shy/reactive pattern: more exploratory capuchin monkeys exhibited increased values of proeminence in Pacing, aberrant sexual display and Active 1 BPIS, while less active animals exhibited increased probability in significant sequences involving at least one BPIS, and increased prominence in own stereotypy. Capuchin monkeys are known for their cognitive capacities and behavioural flexibility, therefore, the search for a consistent set of behavioural indictors of welfare and individual differences requires further studies and larger data sets. With this work we aim contributing to design scientifically grounded and statistically correct protocols for collection of behavioural data that permits comparability of results and meta-analyses, from whatever theoretical perspective interpretation it may receive.
