Fatores que afetam o apoio de residentes ao desenvolvimento do turismo em sítios arqueológicos: um estudo no Seridó Potiguar

The tourist activity , which appropriates spaces and natural , cultural , social and economic scenarios in a given locality , requires a model of integrated development necessarily reconciling the support of residents. In this perspective , this study aims to analyze the factors influencing the support of residents in tourism development in archaeological sites , specifically in the two counties of Parelhas and Carnaúba dos Dantas , in Rio Grande do Norte, in the region of Seridó Potiguar as well as the interrelationship existing between these factors . To achieve the proposed objective of the research , a descriptive -exploratory and quantitative study based on the study of Nunkoo and Hamkisson (2012 ) , using the technique of Structural Equation Modeling - SEM to explain the relationships of the constructs used in this research. Data collection was performed during the periodof May 2013 to July 2013. Among other studies, results indicate that , for the profile of the interviewees used , the higher the confidence of the community residing in the government agencies responsible for, the largest tourism will support the resident to the tourism development and that this supply relationship institutions and government agencies an opportunity to enhance their development strategies and social thinking of the resident agent of tourism . It was also found that the analysis model proposed has a better structural relationship when used interviewees who have knowledge about the activities in the archaeological sites , then suggesting the need for further research on the effect of the level of knowledge of the interviewee on the object and support of residents to tourism development

In situ effect of an erosive challenge on different restorative materials and on enamel adjacent to these materials

Objectives: This in situ study evaluated the effect of an erosive challenge on different restorative materials and on enamel restored with these materials, as well as the ability of these materials to protect the adjacent enamel against erosion.Methods: Ten volunteers wore palatal devices with eight bovine enamel blocks, randomly selected and distributed into two vertical rows, corresponding to the following groups: GI/GV, resin-modified glass ionomer; GII/GVI, conventional glass ionomer; GIII/GVII, composite resin; GIV/GVIII, amalgam. one row (corresponding to groups I-IV) was immersed in a cola drink and the other row (corresponding to groups V-VIII) was subjected to saliva only. The palatal device was continuously worn for 7 days and only half of the appliance (groups I-IV) was immersed in the soft drink (Coca-Cola (R), 150 mL) for 5 min, three times a day. The study variables comprised the wear (profilometry, mu m) and the percentage of surface microhardness change (%SMHC). Data were tested for significant differences by two-way ANOVA and Tukey's tests (p < 0.05).Results: Considering the restorative materials, for %SMHC and wear, there were no differences among the materials and between the saliva and the erosive challenge. For enamel analyses, the erosive challenge promoted a higher wear and %SMHC of the enamel than did the saliva. There were no significant differences in wear and %SMHC of the enamel adjacent to the different restorative materials.Conclusion: This research data suggest that there is little %SMHC and wear of the studied restorative materials and none of them had a preventive effect against erosion on adjacent enamel, which showed a pronounced wear.

O atletismo nos cursos de graduação em Educação Física

This study has the purpose to investigate the characteristics and the role of the athletics-related sports disciplines in four Physical Education undergraduate courses. In order to reach the goal, it was conducted as a qualitative-type research. Data was collected through documental analysis on disciplines briefings and programs, and also from classes observations and interviews with professors and students from the institutions (two State-boarded and two private) responsible for the courses. Through these analyses it was perceived that those disciplines have surpassed some characteristics of the traditional undergraduate program, which is based on sports. Regarding the role of the disciplines, it was noted that professors consider them as responsible for providing students with basic conditions, so they could benefit from sports as instrumental subjects for their professional intervention.

Nas franjas do rural-urbano: meninas entre a tradição e a modernidade

Este artigo gira em torno da possibilidade de reinterpretar dados de pesquisa do passado, à luz das Teorias da Complexidade, conectando-os a dados atuais para conseguir explicações mais compreensivas. São tomados então alguns dados de minhas pesquisas sobre o rural-urbano, a saber: dados quantitativos do Censo de Assentamentos Rurais do Estado de São Paulo sobre as expectativas dos pais em relação à escolarização de meninos e meninas (anos 90); dados qualitativos de uma pesquisa com redações escolares realizada na região de Araraquara no início dos anos 80. Construindo-se uma ponte entre as duas situações, o argumento central é o de que questão das meninas na zona rural deve ser discutida levando-se em conta a relação rural-urbano e superando-se essa dicotomia sob a ótica da história recente do país. Observa-se então que as transformações pelas quais passa a sociedade nacional se refeletem no campo e a conexão entre os dois momentos enfocados (anos 90 versus início dos anos 80) é reveladora de que os germens dessas mudanças já se anunciavam nas relações de algumas meninas que criticavam a sobrecarga do trabalho doméstico sobre os próprios ombros, principalmente sobre os de suas mães.

Improving the field production environment for soybeans

During the past 10 years, soybeans have reached a prominent position among crops in the world. A substantial contribution to world production has been achieved by tropical countries, due to favorable conditions for high yields. Two limitations keep commercial yields below those obtained in experimental results (above 3,000 kg/ha): one is the lack of local adapted varieties and the other is an adequate field production environment. Solutions must be obtained by local research data. Seedbed preparation is one of the most important production steps, since the other production practices are dependent on it. Conventional methods and minimum tillage, when soybeans follow another crop, are being used, with the problem of soil compaction and losses by erosion. Looking for superior strains of Rhizobium is crucial because nitrogen can be supplied by a proper symbiosis. The addition of limestone to the soil is a common practice used to raise the pH to proper levels. The use of fertilizers should be guided by local research findings. Chemical control of weeds, pests and diseases is needed to prevent yield losses, but possible effects on the environment should be considered. © 1981 American Oil Chemists' Society.

Orientation, building height and sky view factor as energy efficiency design parameters

The energy efficiency of buildings should be a goal at the pre-design phase, though the importance of the design variables is often neglected even during the design process. Highlighting the relevance of these design variables, this research studies the relationships of building location variables with the electrical energy consumption of residential units. The following building design parameters are considered: orientation, story height and sky view factor (SVF). The consideration of the SVF as a location variable contributes to the originality of this research. Data of electrical energy consumption and users' profiles were collected and several variables were considered for the development of an Artificial Neural Network model. This model allows the determination of the relative importance of each variable. The results show that the apartments' orientation is the most important design variable for the energy consumption, although the story height and the sky view factor play a fundamental role in that consumption too. We pointed out that building heights above twenty-four meters do not optimize the energy efficiency of the apartments and also that an increasing SVF can influence the energy consumption of an apartment according to their orientation.

Selecting the most adequate bedding material for broiler production in Brazil

Broiler chicken production is widely dispersed across the globe, and one important issue for growers is the selection of adequate bedding material, as the availability and price of substrates varies among countries and regions within a same country. This study aimed at applying a multiple criteria analysis approach for the selection of the most appropriate bedding material for broiler production. Based on field research data and growers' experience, the most desirable characteristics of a litter material were chosen as the main criteria. The selected materials were wood shavings, rice husks, chopped Napier grass (Pennisetum pupureum), 50% sugar cane bagasse (Saccharum L.) plus 50% wood shavings, 50% sugar cane bagasse (Saccharum L.) plus 50% rice husks, and pure sugar cane bagasse (Saccharum L.). The analytical hierarchy process (AHP) was applied for selecting the most suitable bedding material. Validation was performed using data from previous studies carried out in central-western Brazil on the effects of different types of bedding material on broiler carcass quality. Considering the selected criteria, several bedding materials were tested and ranked, and the results showed that wood-shavings litter was the best option (weight = 0.28), followed by rice husks (weight = 0.24). All other tested alternatives presented lower scores and were, therefore, not considered for use. The AHP approach was found to be an efficient tool to select the most appropriate litter material under specific scenarios.
