Racionalidade e pesquisa comportamental no direito: avanço científico ou retórica?

Esse é um trabalho sobre estudos comportamentais que questionam a confiabilidade empírica das premissas de racionalidade das ciências sociais. Décadas de pesquisa comportamental vêm nos ensinando é que a grande maioria das tendências cognitivas identificadas e comprovadas, que se afastam dos pressupostos da Teoria da Escolha Racional não são de forma alguma aleatórias, mas ao invés, são sistemáticas e previsíveis. A ideia unificando esse trabalho é de que a literatura de pesquisa comportamental pode nos permitir modelar e prever comportamentos relevantes para o direito, com pressupostos mais realistas sobre o comportamento humano. No entanto, alguns pesquisadores pintam uma figura entusiástica sobre o potencial que tal pesquisa possui para informar a análise jurídica e, assim, cometem algumas desatenções ao defender generalizações não embasadas por evidências científicas, quase aproximando-se do uso de uma mera retórica. Dado esse cenário, devemos procurar garantir que a incorporação das evidências da pesquisa comportamental no discurso jurídico seja acompanhada de maior ênfase na pesquisa empírica em ambientes específicos. Esse trabalho possui três objetivos. O primeiro é analisar as diferentes concepções de racionalidade e caso elas devem manter sua posição privilegiada nas ciências sociais. O segundo é tentar entender melhor a literatura de pesquisa comportamental que questionam a validade empírica dos axiomas da Teoria da Escolha Racional. O terceiro é identificar problemas na forma pela qual a pesquisa comportamental tem sido incorporada no discurso jurídico.

Ernst Bloch: esperança e educação em tempos de niilismo

This work aims give evidence of that The hope principle, the philosophical system devised by the German philosopher Ernst Bloch, in which hope assumes an ontological character, offers cognitive support that allows overcoming the void imposed by nihilism today, especially in the field of education. But while it offers cognitive support, it also presents a need that is fulfilled by an educational proposal based on a not-yet-conscious being. An education based on hope has four essential pillars: learning to know, learning to do, learning to be, learning to live together and, most of all, immerging into in the seas of uncertainty. In times when school is a promoter of certainties at the expense of uncertainties, education must not forsake the notion of the unpredictable and immeasurable, nor the need to find ways to enable better understanding of aspect related to the not-yet-be. The employed theoretical and methodological elements in this work paint a corpus through an interactive process in which layers of additional texts are subjected to analysis

Thermal comfort indices in individual shelters for dairy calves with different types of roofs

Dentre os materiais de construção utilizados nas instalações rurais, merecem destaque as coberturas, pois são grandes responsáveis pelo conforto térmico, influenciando no balanço térmico no interior das instalações. Este trabalho objetivou avaliar a influência das coberturas sobre a entalpia (H), Carga Térmica Radiante (CTR) e no Índice de Temperatura de Globo Negro e Umidade (ITGU), em abrigos individuais para bezerros leiteiros. O delineamento foi o inteiramente casualizado com três tratamentos: Z - telha de zinco; CA - telha de cimento amianto, e CAB - telha de cimento amianto pintada de branco na face superior. As médias foram comparadas pelo teste de Scott Knott, a 1% de probabilidade. Os resultados mostraram que não houve diferença estatística entre os tratamentos (P<0,01) e o ambiente externo, para a H. Para a CTR, houve diferença estatística entre todos os tratamentos, em que CAB demonstrou menor CTR, 489,28 W m-², seguido do tratamento CA, 506,72 W m-², e Z com maior valor de CTR, 523,55 W m-². Para o ITGU, observaram-se menores valores para CAB (76,8) e CA (77,4), diferindo-se, significativamente do Z, que obteve maior valor (81,6). As telhas com pintura branca em sua face superior promoveram menor CTR e menor ITGU, favorecendo o ambiente térmico da instalação.

Estudo térmico de um sistema solar de aquecimento de água residencial para duas configurações de superfície absorvedora

It presents a solar collector to be used in a system for heating water for bathing, whose main characteristics are its low cost and easy manufacturing and assembly. The absorbing surface of the collector is formed by an aluminum plate with eight flaps where they lodge PVC pipes. The catchment area of solar radiation corresponds to 1.3 meters. The collector box was made of wood, is covered by transparent glass and thermal insulation of tire chips and expanded polystyrene (EPS). Absorber tubes were connected in parallel through the use of PVC fittings and fixed to the plate by the use of metal poles and rivets. The entire absorber received paint flat black for better absorption of sunlight. The system worked on a thermosiphon assembly and absorber of the collector has been tested in two configurations: with the tubes facing up, directly exposed to the impact of sunlight and facing down, exchanging heat with the plate by conduction. It was determined the most efficient configuration for the correct purpose. The solar collector was connected to a thermal reservoir, also alternative, low-cost forming the system of solar water heating. We evaluated thermal parameters that proved the viability of the heating system studied

(Por) entre pedra e tela: a construção de uma memória republicana (Natal - 1906-1919)

This work, from a perspective that thinks the space as a historical category, and especially as a relationship which stresses the role of objects, proposes an analysis of the construction of a Republican memory in the city of Natal in the early twentieth century. This research will focus mainly on two objects: the obelisk opened in 1917, and the Andre de Albuquerque Square on the occasion of the celebration of Frei Miguelinho´s death centenary and the paint Julgamento de Frei Miguelinho ordered by the State Government to the painter Antonio Parreiras, picture that was in the Salão Nobre do Palácio do Poder Executivo of that time. In a geral way this work intend to analyse the construction of this memory as well as the role of these objects in this process. To achieve that, we propose to trace ways and networks to follow the possible associations(between people, events, images, discourses, objects, institutios etc.) in the constitution of mutual belongings. Thus, our procedure was to follow these objects through the pathways in which they became possible, so that in the end we could defend the idea that they are active participants of the process that establish them.

Assinaturas antropogênicas de elementos maiores e traços em poeira urbana na cidade do Natal-RN

Although there are many studies on urban dust contamination by heavy metals in developed countries, little attention has been paid to this type of study in developing countries, including Brazil. Therefore, a series of investigations were performed to provide signatures of heavy metals in urban dust and assess the potential sources in the city of Natal - RN-Brazil. The fraction of these sediments was studied to pass through a sieve of 63 micrometers. For the study analyzed two groups of samples, one collected in September 2009 at the end of the rainy season (9 samples) and one collected in January 2010 in the dry season (21 samples). So in all, thirty sediment samples were collected from the street. Then, in Fluorescence Spectrometry X-rays were determined major elements SiO2, Na2O, K2O, Al2O3, MgO, P2O5, Fe2O3, MnO, TiO2 and CaO, and trace Rb, Cr, Ni, Cu, Zn, Sr and Pb by an ICPOES was determined Zn, V, Na, K, Ni, Mn, Mg, P, Fe, Cr, Cu, Pb, Ba, Ca and Al from leaching HCl 0.5 mol L-1 . The results of the concentrations of elements show that the greater presence of these occurs in the dry season, except for Si which is higher in the rainy season. Analyses by geoaccumulation Index (IGEO) Enrichment Factor (EF), Contamination Factor (CF), analysis correlation and Hierarchical Cluster, confirm that Zn, Cu and Pb is anthropogenic character. Zinc may be derived from various sources related to motor vehicles or the road signs and street grids. The elements Na, K, Mg and Ca may be related to droplets suspended in air containing cations and anions present in seawater (salty), common in Christmas throughout the year, brought by winds SE-NW. The elements Na, Mg, Ca and K are the most abundant in seawater and were analyzed in this study. This indicates that the source of these additional elements detected by analyzing the contamination factor may be the very sea. Moreover, Ni, Fe, Cr and Ba can be either as a source of anthropogenic geogênica. The source of Ca is different, because it comes in lime and paint (painting guides of buildings and streets) in construction materials, but may also be present in sediments in the fragments of shells or carbonate bioclasts common in the coastal area

Territorialidade e pesca: atualidades e tradições no uso dos recursos pesqueiros na comunidade litorânea da praia da Pipa Rio Grande do Norte

The need for sustainability in the exploitation of natural resources in coastal areas has been out in recent years, as well as the social and cultural sustainability of traditional communities in these regions. Coastal and estuarine wild areas are influenced directly or indirectly by a set of human activities such as artisanal fishing. Therefore, there is a demand for an integrated design of these areas and according to the landing values, a pattern of unsustainable development of national marine fishing activity. The study was conducted in the coastal community of Praia da Pipa, Tibau do Sul municipality, RN, between june 2009 and june 2010 and aimed to characterize the fishery performed, its socio-economic strategies and fishing areas, as well as to identify ichthyofauna, to assess the sustainability of the major resources and to identify cultural traits related to artisanal fisheries, their problems and prospects; linking tradition and the present fishing activity carried out in the community. For this study, a total of 67 structured interviews were collected, including qualitative and quantitative data. A total of 133 fish landings and direct observations were performed. Informants were identified according to one of the following categories: fishermen, vessel masters and members of the local population with offspring. Applications SPSS 10.0, Paint.Ink and Microsoft Office Excel 2007 were used for tabulation and analysis of results. Local fishermen are, on average, 25 years fishing, have 40 years old and the average monthly income is up to 03 minimum wages. The local fleet consists of 20 vessels, that uses different line sizes and types of networks, operating in 21 fishing grounds and showing a reduction in the vessel numbers by 66% in the last decade. We recorded 76 species of fish, captured by the local fleet and the top 5 were quantitatively analyzed serra spanish mackarel (Scomberomorus brasiliensis), little tunny (Euthynnus alleteratus), yellowtail snapper (Ocyurus chrysurus), red snapper (Lutjanus analis) and common snook (Centropomus undecimalis), accounting for 46,5% of production in the period. The capture of these species was composed mostly of adults. Data analysis showed a significant decrease of the local fishing activity over the last decade due to the weakness displayed by the political-social category, the devaluation of local knowledge and the emergence of new sources of income through increased tourism. The characteristics of the fishing community suggest it to pass through significant changes as the appreciation of their cultural and traditional aspects. We identified a tendency to sustainability of main species caught, suggesting that public policies to be adopted locally comply with the current characteristics of fishing undertaken in the community and knowledge of fishermen related to the environment, allowing environmental, as well as social and cultural sustainability of the community involved.
