This study aimed to evaluate the potential of two public schools in Educommunication related to Environmental Protection Area Jenipabu (APAJ) located in Rio Grande do Norte / Brazil, based on perceptions of educommunicatives practices on the environment as well as perform an action included in the school APAJ. In the first phase of the research were three separate questionnaires designed to identify the actions, practices and experiences of three sets of audiences: teachers, students and parents from both schools. In the second phase, activities were carried out as educomunicatives class actions involving ride, maps of environmental design and construction of a mural on the school newspaper APAJ. We opted for the participant, making the observation in a previous visit to knowledge of the schools, where they made the first contacts with the administrative team, teachers and students, and then the application of semi-structured questionnaire to teachers, students and parents of the 4th and 5 years of elementary school the morning hours. The results showed the detachment of these actors in the knowledge, participation and involvement with APAJ, caused by the absence of actions and actions involving teaching practices educomunicatives students to interact with the environment, taking as its starting point the living space.

The water quality of many reservoirs in the world has been reduced due to percolation of contaminants to water, which can have natural or anthropogenic origin, increasing the level of genotoxic compounds in aquatic ecosystems. This fact has contributed to the reduction of environmental quality, and commitment the health of living beings that inhabit these ecosystems, including the human population. In this backdrop of reduced water quality, is the Lucrecia dam, which is a major surface water reservoirs by volume of semi-arid region of Rio Grande do Norte, and that has shown contamination by heavy metals, cyanobacteria toxic and the natural presence of Radon. The population that use this source has been showing high rates of cancer, popularly associated with the consumption of this water, with a prevalence about three times higher compared to the whole state of Rio Grande do Norte. Based on this, the present study aimed to evaluate the mutagenic potencial of surface water from the Lucrecia dam, using the Micronucleus Test in Tradescantia pallida (Trad-MN) and in human peripheral blood lymphocytes (CBMN) assay, as well as identify the concentrations of some heavy metals in this water. Water samples were collected on a dry season and a rainy season, in two distinct points. Moreover, in order to bring a completely view about the relationship of man-health-environment in this local, through the knowledge of knowing / acting environmental from residents of Lucrecia, and the use and perceptions they have about the dam of your city, a study of Environmental Perception was carried out with local residents. The results obtained for the both micronucleus test, showed significant results for the three points analyzed. The strongest mutagenic effect was observed in the dry season for both assays. Chemical analyses detected an increase of heavy metal levels in different points and season above the maximum allowed by legislation. Regarding the study of Environmental Perception with local residents, it was observed the knowledge of the environment that the residents have, as well as the strong ties and perceptions with the dam of the city. Thus, the combination of these two aspects (the genetic toxicity tests conducted in the dam together with analysis of environmental perception with the residents of Lucrecia) allowed to draw a more complete diagnosis on the local situation

Intensive production of tilápias, in cages or net tanks, has been proposed as an alternative to increase fish production, that would generate income and offer animal protein in different tropical and subtropical countries. However, this system of production enriches the aquatic environment with nutrients, principally nitrogen and phosphor derived from the dejections of the metabolism of food and eventual food surpluses consumed by the fishes; the alimentation of the fishes in this production modality is dependent on fish food. The emission of these nutritions in levels above the limit that the system is capable metabolize can provoke a phenomenon called eutrofization, putting in risk the quality of water for public and for fish production activities. In this context the work had as a goal to evaluate the trófico state of the four reservoirs for intensive production of tilapias in net-tanks, in other words, he maximum fish production that the reservoirs are able to hold, keeping the desired quantity of nutrient concentrations in water for public use. The results of the four ecosystems in the Boqueirão de Parelhas reservoir showed that it s possible to have an intensive production of tilapias in net tanks, in this environment the annual average concentration of phosphor, was below the considered critical limits to deflagrate the process of eutrofization in semi-arid regions. The carrying capacity of the Boqueirão de Parelhas reservoir depends on the conversion of the feeding facts and phosphor content in the food but it should vary between 100 and 300 tons per year over a variation in the conversion feeding factor of 1,7 to 2,0:1 and a variation in the P in the food of 0,7 to 0,9%

The present study aims to understand the perception in a manager perspective of the relationship between the stakeholders of tourism and environmental management in João Pessoa (PB). It is a qualitative, transversal, descriptive and exploratory research, held with keys stakeholders of tourism and environment in the capital of Paraíba. The data were collected through structured interviews and the analysis of the minutes of the municipal council of tourism, called COMTUR/ JP. The data research allowed us to affirm that the environmental stakeholders have a higher academic background than those of tourism, on the other hand the tourism stakeholders‟ have longer experience time than the environmental stakeholders‟. In general, the use of environmental resources for tourism is noticed as positively by the tourism stakeholders‟ and as intermediate for the environmental stakeholders‟, the tourism development is consider to be a non predatory active in João Pessoa, but it is very concentrate in the coastal area, the remnants of Atlantic Forest or protected areas are not used for tourism. The main environmental impacts cause by tourism according to the stakeholders interviewed (tourism and environment) were the environmental degradation of reef, beach pollution and the construction of tourism facilities in areas that should be protected, however, there was a stakeholder who believes that the tourism development in Paraíba is so nascent that it is unable to impact the environment. The performance of SETDE, PBTUR and SUDEMA was consider inconsistent by some of the interviewed stakeholders‟. The NGO representatives believe that the most important thing is a paradigm shift from the entrepreneurs and the local population. Despite the apparently close relationship between tourism and environment management in João Pessoa (PB), some actions of tourism agencies and the state government has left some unhappy important environmental stakeholders indicating that the relationship between tourism and environment in the city is becoming tenser each year

La presente pesquisa contempla reflexiones referentes de la actividad turística en la organización socio-espacial en el litoral de las comarcas de Extremoz y Ceará-Mirim, región de la Grande Natal. Nuestro objetivo principal es el estudio de las transformaciones del espacio y de sus implicaciones socio-ambientales en curso en el proceso de producción del espacio turístico en el litoral de las referidas comarcas desde 1997 hasta 2007, momento de importancia publica-privada que, a partir del PRODETUR, tuvo la base para el incremento de las potencialidades turísticas. En este sentido, varias fueron las técnicas para una mejor compresión de las aspiraciones y de la percepción de los actores envueltos con la actividad turística (comerciantes, turistas, populación y poder publico local) para conocer cuales son sus consideraciones en cuanto a los cambios que proceden de la implantación de la actividad turística en el lugar, cuanto a la mejora de la calidad de vida, de la generación de empleo y de renta, comercialización, conservación, preservación del ambiente, cumplimiento de la legislación, afirmación cultural así como las acciones puestas en ejecución en las comarcas. Para tal necesidad, se buscó analizar los datos estadísticos a partir del uso de los cuestionarios con preguntas estructuradas y semi-abiertas como instrumento de colecta de información que les era correlacionada con la opinión de los actores locales de modo que podamos formar y entender los elementos básicos que son parte de los espacios turísticos en foco. Fueran utilizadas fotografías aéreas de las comarcas de Extremoz y Ceará-Mirim, provistas por el IDEMA, con la intención de percibir acerca de los cambios del espacio y las implicaciones socio-ambientales de la área en estudio. Concluimos en función de los resultados que el modelo de Turismo concebido por lo Brasil, estimulado y financiado por lo Gobierno Federal, está insertado en el contexto de la economía global y, por lo tanto, el Estado del Rio Grande del Norte, en específico los espacios litoraneos de las comarcas de Extremoz y Ceará-Mirim, que poseen características similares a este modelo, con sus particularidades, que si traduzca por la exclusión social, formas de apropiación privada de los espacios público y áreas de protección ambiental como las playas, las dunas y las lagunas, el desacato o no el cumplimiento de la legislación ambiental, aumento de las desigualdad de renta en una región que posee una problemática social grave y sin inversión, implantación de la infraestructura, ausencia de política pública local, donde los intereses económicos son prioridad delante de las aclamaciones populares. Se sugiere un repensar cuanto al modelo actual de desarrollo adoptado, que el planeamiento sea pautado en base a la participación integrada de los varios agentes implicados con la actividad turística, incluyendo en la medida del posible, las aspiraciones de la población local como precusoras de sus reales necesidades, donde esta acción interactiva contestará ciertamente en un esfuerzo significativo en la construcción de un nuevo paradigma, modelo del desarrollo sustentable, siendo posible superar gradualmente el incremento de la pobreza, de la exclusión y de los impactos ambientales, donde la calidad de vida sea factor fundamental

The changes ocurred in the world of capitalist labor, especially from the last decades of the 20th century, accentuated the process of manipulation and domination of the working class, materialized mainly through naturalization and / or trivialization of violence, conducted in the work environment. From this process, emerge the elements of bullying, that is, the embarrassing and humiliating practices which extend through time, degrading human race, and becoming fruitful object for study, debate and the intervention of the professionals of the Social Service area. Thus, we assume the perspective of analyzing the concepts and the work of social workers, whom work at people management area before the bullying in the workplace. We propose the following objectives: apprehend the settings of bullying, in the contemporary context of competitiveness and flexibility of work, as well as its implications for workers' health; characterize the background of this expression of violence at work in the municipality of Natal- RN; and analyze the powers and duties of the social worker in the process of prevention, identification and addressing of bullying in the context of work. This study consisted of a qualitative approach, based on the dialectical-critical method as soon as we adopt methodological procedures such as: theoretical knowledge, documental and field research, and performed using semi-structured interviews. The subjects of this research were nine (09) the Social Service professionals working in personnel management area, in five (5) institutions with legal and branches of different activities, located in Natal-RN. Even interviewed one (01) representative of the Public Ministry of Rio Grande do Norte Office (MPT-RN). The findings of this analysis indicate that bullying is a contemporary expression of "social question", which is presented as a demand for the Social-assistants – covered up and / or camuflage – under the guise of problems related to workers' health or mere conflicts of interpersonal relationships, that is, without any causal connection with the organization of work. The fear of losing job, not to be inserted in the labor market, and / or suffering reprisals, deepens the subject levels of the victims of bullying. Hence the importance of Social Workers are capable to understand the social reality, by preventing and combating the elements of bullying.

The spatial and temporal distribution of the population reflects the adjustment of their biological characteristics to environmental conditions and biotic interactions as adaptive and phylogenetic precursors elements. The habitat’s heterogeneity and alternating seasons tend to cause patterns of activity of organisms and species diversity. However, these seasonal and spatial patterns in butterfly communities in dry environments are not yet clear. We studied a community of frugivorous butterflies in ESEC Seridó, in northeastern Brazil, aiming to characterize the guild in semiarid and check the relative contribution of climate and vegetation variables on its composition, diversity and phenofaunistic. The butterflies were sampled monthly during one year, and the distribution of species was associated with structural characteristics of three vegetation types (eg. richness and abundance of tree and shrub species, canopy cover, herbaceous cover, litter) and climatological data (temperature, rainfall and humidity). We captured 9580 individuals of 16 species of butterflies belonging to four subfamilies (Biblidinae, Charaxinae, Nymphalinae and Satyrinae). The richness, abundance and diversity varied in different scales, especially in time, being higher in the rainy season, while the β-diversity and turnover was higher in the dry. The distribution of species mainly followed the changes in humidity, rainfall and vegetation phenology, with no defined boundaries between habitats. The flight period was shared within subfamilies, which should have distinct response to environmental stimuli, as well as respond to the phenology of host plants and have different reproductive strategies. There is even evidence of physiological and behavioral adaptations as seasonal reproduction and aestivation. So there was environmental control over the distribution and diversity of species, with the key role climate Association and vegetation structure in the community of differentiation in the seasons, and the availability and quality of resources on the variation of species abundance in small scales. These results may support the biomonitoring and conservation preserved areas, particularly in environments under human pressure and extreme environmental conditions such as semi-arid.

Currently, the growing aging population challenges the society and public health policies, for increased longevity need to be associated with quality of life. Adequate physical and social environment are key factors for the welfare of the elderly, particularly the housing environment - this thesis understood as the home (dwelling unit) and its surroundings (close proximity). In addition, Brazilian legislation in this sector indicates the importance of the elderly remain at home and in the family. In addition, Brazilian legislation in this sector indicates the importance of the elderly remain at home and in the family. Based on this framework mortar, the thesis was starting questions: How do you live the elderly population aged 80 and over which is served by the Health Family Strategy of the Unified Health System? That social and environmental conditions of the place of residence act more directly on their quality of life? How do these people get housing conditions experienced? The research aimed to investigate how the residential environment (social and physical) influence everyday activities and quality of life of the elderly. Exploratory qualitative study highlighting the home visits, developed based on multimethod strategy. The empirical study was conducted in the city of Cabedelo-PB, Nov/2013 to Feb/2014. Participants were 36 elderly people (31 women and 5 men) aged between 80 and 99 years, little education, who live 39 years in the area (average). In the research first stage were applied questionnaires for socio-demographics and livability of the residence and the surroundings. In the second stage we used semi-structured interview and a tour accompanied in the neighborhood (with those who have accepted to do so). Throughout work it was kept a diary by the researcher and held naturalistic observations of the behavior of the elderly. Quantitative data were described using descriptive statistics, and information from the interviews were analyzed through the Collective Subject Discourse technique. Among the key ideas that emerged from them are: the representation of home, neighborhood support and related issues dyad independence / autonomy. The study showed that the elderly develop strong attachment to the place where he lives, the importance of it for your health and the desire to stay there. Thus, despite experiencing many barriers (more physical than the social), at the place where they live, they say they are satisfied, even when unfavorable conditions are evident. Concluding that as the houses are environmentally more docile, simple changes ensure autonomy, independence and mobility for the elderly. In turn, the barriers of the urban environment show it more difficult to deal with, making this space inhospitable to most survey participants, a condition that hinders your physical activities and social participation, and negatively influence their quality of life.

The present thesis aimed at understanding how the insertion of music in the work environment contributes to achieving Quality of Work Life. - QWL, under the perspective of biopsychosocial and organizational well-being. As to music insertion we considered the theoretical-empirical perception about how music is inserted at work and its functions on such place. The context where the study was taken was the manufacturing area of a major textile company, located in Natal, state of Rio Grande do Norte, Brazil, in which music is used during labor activities. The only study case was the research strategy adopted, with exploratory and descriptive purposes. The primary data were collected through the focus group technique, applied to the collaborator in the manufacturing sector. The semi-structured interview was done as a complementary tool, directed to the supervisor in that sector. Respecting the theoretical saturation criterion, we formed four focus groups, each one composed of eight members randomly selected, among the seventy-six collaborators in the sector. The data were analyzed qualitatively, through the content analysis technique, more specifically the category analysis. We identified twenty-eight QWL attributes. Six of them were found present in the four focus groups and in the interview. Among these ones, the attribute of Interpersonal Relationship at Work, contemplating the Psychological and Organizational dimensions, was the only one anticipated in four out of fifteen theoretical models here listed. The attribute Music at Work Environment could be inserted in the four QWL dimensions, highlighting the power and relevance of this attribute for the research participants. The way music has been inserted in the labor environment contributes to promoting well-being at work, which goes against theoretical conceptions, especially when it comes to musical genre. We identified nine functions of music at work, among which, Improving Work Conditions, Improving Interpersonal Relationship at Work and Favoring Motivation for Work had to be emphasized for being associated to three QWL attributes. In the total, we highlighted seven associations. The most affected QWL dimension through the insertion of music at work was the Psychological one, followed by the Organizational one. We conclude that music insertion provides biological, social and, above all, psychological and organizational well-being to the contributors, thus contributing to obtaining QWL at the labor environment researched. However, we should consider the context and proceed to periodical plans and adjustments in the way of music insertion so as to avoid health and well-being problems to those people at work

This study aimed to examine how students perceives the factors that may influence them to attend a training course offered in the distance virtual learning environment (VLE) of the National School of Public Administration (ENAP). Thus, as theoretical basis it was used the Unified Theory of Acceptance and Use of Technology (UTAUT), the result of an integration of eight previous models which aimed to explain the same phenomenon (acceptance/use of information technology). The research approach was a quantitative and qualitative. To achieve the study objectives were made five semi-structured interviews and an online questionnaire (websurvey) in a valid sample of 101 public employees scattered throughout the country. The technique used to the analysis of quantitative data was the structural equation modeling (SEM), by the method of Partial Least Square Path Modeling (PLS-PM). To qualitative data was the thematic content analysis. Among the results, it was found that, in the context of public service, the degree whose the individual believes that the use of an AVA will help its performance at work (performance expectancy) is a factor to its intended use and also influence its use. Among the results, it was found that the belief which the public employee has in the use of a VLE as a way to improve the performance of his work (performance expectation) was determinant for its intended use that, in turn, influenced their use. It was confirmed that, under the voluntary use of technology, the general opinion of the student s social circle (social influence) has no effect on their intention to use the VLE. The effort expectancy and facilitating conditions were not directly related to the intended use and use, respectively. However, emerged from the students speeches that the opinions of their coworkers, the ease of manipulate the VLE, the flexibility of time and place of the distance learning program and the presence of a tutor are important to their intentions to do a distance learning program. With the results, it is expected that the managers of the distance learning program of ENAP turn their efforts to reduce the impact of the causes of non-use by those unwilling to adopt voluntarily the e-learning, and enhance the potentialities of distance learning for those who are already users
