Marco teórico-metodológico de los estudios del paisaje: Perspectivas de aplicación en la planificación del turismo
dos Santos Pires,Paulo;
Estudios y perspectivas en turismo , 2011,
Abstract: this article consists of a theoretical-methodological essay that focuses on the relationship between landscape and tourism. this relationship is outlined based on the recognition that the landscape constitutes an entity that cannot be disassociated from tourism, as every tourism experience involves the active of perception - predominantly visual - of the landscape visited, making it a important element of the tourism phenomenon and a resources of high value in the development and consolidation of the tourism offer. however, landscape studies, in their esthetic or visual dimension, are a field of knowledge that has been little explored by academics in the area of tourism in brazil, despite its inherent importance for the planning and development of tourism spaces and destinations. the objective of this article, therefore, is to outline the essential elements of this field of knowledge, in terms of their conceptual and methodological aspects, and to highlight their potential application in tourism planning. the topics presented follow an order that is coherent with the central theme expressed in the title; it begins with an outline of the tourism value of the landscape, followed by a concise summary of the theoretical background to landscape studies, and also its methodological background; it then goes on to focus on the quality, fragility and visual impacts as parameters for the incorporation of the variable, or of the category "landscape" in operational models that can be applied in tourism spaces and in their environmental context.
Marco teórico-metodológico de los estudios del paisaje: Perspectivas de aplicación en la planificación del turismo The Theoretical-Methodological Framework of Landscapes and its Prospective Application in Tourism Planning
Paulo dos Santos Pires
Estudios y perspectivas en turismo , 2011,
Abstract: Este artículo es un ensayo de fundamentación teórico-metodológica sobre la relación entre paisaje y turismo, delineada a partir del reconocimiento del paisaje como un ente indisociable del turismo, ya que toda experiencia turística implica un acto de percepción predominantemente visual, del paisaje visitado, convirtiéndolo en un elemento substancial del fenómeno turístico y en un recurso de gran valor para el desarrollo y la consolidación de la oferta turística. Los estudios del paisaje, en su dimensión estética o visual conforman un campo del conocimiento poco explorado, más allá de su importancia para la planificación y el desarrollo de espacios y destinos turísticos, en el medio académico del turismo en Brasil. De esa forma, el objetivo de este artículo es exponer los elementos esenciales de este campo del conocimiento en sus aspectos conceptuales y metodológicos además de considerar sus posibilidades de aplicación en la planificación turística. Dado que los tópicos presentados siguen una línea estructural, se comienza con el abordaje del valor turístico del paisaje para luego exponer concisamente el marco teórico de los estudios sobre el paisaje y su cuadro metodológico, enfocando ambos temas en la calidad, fragilidad e impactos visuales como parámetros para la incorporación, tanto de la variable como de la categoría "paisaje", en los modelos operativos de posible aplicación en los espacios turísticos y su contexto ambiental.

Abstract: We discuss the structure of "exceptional generalised geometry" (EGG), an extension of Hitchin's generalised geometry that provides a unified geometrical description of backgrounds in eleven-dimensional supergravity. On a d-dimensional background, as first described by Hull, the action of the generalised geometrical O(d,d) symmetry group is replaced in EGG by the exceptional U-duality group E_d(d). The metric and form-field degrees of freedom combine into a single geometrical object, so that EGG naturally describes generic backgrounds with flux, and there is an EGG analogue of the Courant bracket which encodes the differential geometry. Our focus is on the case of seven-dimensional backgrounds with N=1 four-dimensional supersymmetry. The corresponding EGG is the generalisation of a G_2-structure manifold. We show it is characterised by an element \phi in a particular orbit of the 912 representation of E_7(7), which defines an SU(7) (subset of E_7(7)) structure. As an application, we derive the generic form of the four-dimensional effective superpotential, and show that it can be written in a universal form, as a homogeneous E_7(7)-invariant functional of \phi.
O trabalho em emergência: entre o prazer e o sofrimento
Paulo Jorge dos Santos Almeida,Denise Elvira Pires de Pires
Revista Eletr?nica de Enfermagem , 2007,
Abstract: O trabalho nos servi os de urgência e emergência hospitalar pode ser satisfatório e fonte de prazer, mas, muitas vezes, cansativo e fonte de sofrimento. Este estudo tem como objetivo identificar os fatores causadores de prazer e de sofrimento no cotidiano de uma equipe que atua num servi o de emergência. Para tal foi efetuada uma pesquisa qualitativa, descritiva e exploratória e foram utilizadas como técnicas de coleta de dados a entrevista semi-estruturada e a observa o sistemática. O estudo foi realizado entre Novembro de 2006 e Maio de 2007, num hospital de ensino localizado na regi o sul do Brasil. Nele participaram 17 profissionais de saúde, cerca de 20% dos trabalhadores que constituem a equipe de saúde do servi o de emergência. Os resultados obtidos apontam como fontes de sofrimento no trabalho o acesso indiscriminado à emergência, as cargas elevadas de trabalho e o espa o físico inadequado. Como fontes de prazer foram apontadas a possibilidade de ajudar os usuários, a possibilidade de exercer a profiss o na plenitude, a dinamica do servi o e a pouca existência de rotinas. O estudo permite concluir que os trabalhadores da emergência estudada vivenciam diariamente prazer e sofrimento no trabalho, numa rela o dialética que lhes permite manter o equilíbrio psíquico.

Abstract: in a capitalist society, organizational decisions, usually aimed at the economic dimension, triggered or exacerbated the socio-environmental problems in many countries. in the search for solutions to such problems arises in the 1980s the concept of sustainable development proposing to meet the needs of present generations without compromising the care of the needs of future generations (comiss?o mundial sobre meio ambiente e desenvolvimento, 1988). considered a subjective concept and open to interpretation, sustainable development, includes support of three essential dimensions: the economic, the social and the environmental one. thus, under the organizational perspective, to make decisions that contribute to sustainability, has become at least a big challenge, because beyond the economic dimension, decision makers must deal simultaneously with the social and environmental dimensions. this shows that there are levels of decisions defined as simple, average, and complex and that these levels tend to influence or compromise the achievement of sustainability differently, depending on the service satisfactory or not of the dimensions. faced with this challenge this paper, while theoretical essay aims to present an understanding of sustainability through the level of complexity of organizational decisions. to achieve this goal, it is proposed the relevant criteria that compose each dimension of sustainability, identifying the relationships (systemic) that may occur between the criteria for organizational decision making. as a result of crossing between levels of complexity of decisions and the dimensions of sustainability, a structure of a complex matrix of decisions was obtained to address sustainability. the qualitative matrix shows how the decision-maker or researcher may classify the decisions considered relevant and how he can make complex decisions that integrate satisfactorily the three dimensions of sustainability.

Abstract: objective: atherosclerotic inflammation, with a possible role of infectious agents, could contribute to the pathogenesis of abdominal aortic aneurysms (aaa). finding of chlamydia pneumoniae (cp) in these lesions in previous, non-quantifying studies ranged from 0-100%. the objective is to quantify the presence of cp and mycoplasma pneumoniae (mp) in aaa. methods: thickness, number of cells positive for cp by immunohistochemistry and percent area occupied by mp, detected by "in situ" hybridization in the three layers of the aorta, were measured in the three aortic layers using an image-analysis system in 10 necropsy abdominal aneurysmatic aortas. three groups of controls were used: 1) samples of the same aortas, outside the aneurysms, except if the dilatation took the whole sub-renal portion of the artery (n=7); 2) aortas with severe atherosclerosis but without aneurysms (n=10); 3) aortas with no or mild atherosclerosis (n=10). all specimens were obtained at necropsies. wald's test was used to compare groups; significance level was established at 5%. results: the intima was thinner and the media thicker in the normal cases than in the other groups (p<0.01). positive cells for cp were found in all groups, more frequently at the adventitia; no significant difference was detected between them (p>0.05). mp was also detect in all groups. this agent predominated in the group of patients with atherosclerosis, but no aneurysms at both intima and adventitia; nevertheless, differences between the groups were not significant (p>0.05). conclusions: our data suggest that the bacteria we focused have not an important role in the pathogenesis of aaa.
Moderniza??o rural: transforma??es econ?micas e suas implica??es demográficas, epidemiológicas e nutricionais nos municípios de Monteiro Lobato e Santo Ant?nio do Pinhal

Abstract: this paper approaches the query on why agriculture modernization, although promoting substantial gains in productivity, did not succeed in chasing away the specter of famine for great portions of the world population, with significant impacts over their health. it intends to verify whether or not the paradigms of epidemiological and nutritional transitions would apply to the study of populations that were rendered deprived in the process of modernization of agriculture in the municipalities of monteiro lobato and santo ant?nio do pinhal, state of s?o paulo, brazil. the insertion of these municipalities into the so-called agriculture modernization was assessed through the use of farming and cattle raising inputs. coefficients of general mortality and curve of proportional mortality were used to verify the epidemiological transition. nutritional transition was addressed to through the secular tendency of growth, prevalence of obesity and, feeding habits. it was observed that, notwithstanding the significant fall in infant mortality, the secular tendency of growth for those who were born or who have passed their first infancy within those municipalities was rendered effectively true, in a discrete fashion, only for women, indicating, this way, a deficiency in terms of energy consumption. on the other hand, the prevalence of obesity is high, mainly among women. the population's diet is monotonous, with low-energy density. it concludes that the paradigms of epidemiological and nutritional transitions, based on a phase- and developmental-wise approaches of the morbid-mortality processes, are neither able nor enough to explain the complexity of the situations described in this paper.
Nature vs. Nurture: the Making of the Montado Ecosystem
Paulo Miguel Pereira,Manuela Pires da Fonseca
Ecology and Society , 2003,
Abstract: The southern Iberian Peninsula is dominated by a savannah-like ecosystem, the montado, which is a typically Mediterranean cultural adaptation to generally poor productive areas. Montados are exploited for three main uses: forestry, agriculture, and extensive grazing, in proportions that vary according to local conditions (more or less productive land) and historical circumstances. Because these ecosystems occur over a large geographic area (they occupy some 6 million ha), biodiversity would be expected to vary among montados. However, differences in management practices may also influence species distribution. In this paper, we investigate differences in plant and bird species diversity among 60 montados distributed all across southern Portugal. The environmental variables studied included geographical coordinates, climatological data, soil type, and altitude. We also investigated agro-economic variables that could describe human activities at each site: animal husbandry (breeds, stock density, grazing rotation, etc.), agriculture (fallow rotation frequency, use of fertilizers, etc.), and forestry (cork harvesting, thinning, etc.). Finally, land-use type and metrics were assessed from rectified aerial photographs. Species richness among these two groups was not correlated, sites with high or low numbers of plant species not necessarily having high or low numbers of bird species. However, both plant and bird communities exhibited a similar pattern of species composition and turnover. This pattern was ecologically based, rather than a result of biological similarities between groups: direct gradient analyses and variance partitioning revealed strong correlations between species distribution and spatial gradients, namely longitude and latitude. In trying to distinguish anthropogenic from biophysical processes, we found that both were equally important as drivers of montado biodiversity. Plants and birds exhibited a similar ecological pattern, although environmental conditions were slightly more important in the case of plants, and human activities were slightly more important in the case of birds.
Uma compreens o da sustentabilidade por meio dos níveis de complexidade das decis es organizacionais.
Andrei Giovani Maia,Paulo dos Santos Pires
Revista de Administra??o Mackenzie , 2011,
Abstract: Em uma sociedade capitalista, as decis es organizacionais, geralmente voltadas à dimens o econ mica, desencadearam ou agravaram os problemas socioambientais em muitos países. Na busca por solu es de tais problemas, surge, na década de 1980, o conceito de desenvolvimento sustentável, propondo o atendimento das necessidades das gera es atuais sem comprometer o atendimento das necessidades das futuras gera es (COMISS O MUNDIAL SOBRE MEIO AMBIENTE E DESENVOLVIMENTO, 1988). Considerado um conceito subjetivo e passível de interpreta o, o desenvolvimento sustentável prop e o atendimento de três dimens es essenciais: econ mica, social e ambiental. Assim, sob a ótica organizacional, tomar decis es que contribuam para a sustentabilidade tornou-se, no mínimo, um grande desafio, pois, além da dimens o econ mica, os decisores dever o lidar simultaneamente com as dimens es sociais e ambientais. Isso mostra a existência de níveis de decis es definidos como simples, medianos e complexos, os quais tendem a comprometer ou influenciar de forma distinta o alcance da sustentabilidade, conforme o atendimento satisfatório ou n o das dimens es. Diante desse desafio, como ensaio teórico-metodológico, este artigo tem como objetivo apresentar uma compreens o da sustentabilidade por meio dos níveis de complexidade das decis es organizacionais. Para alcan ar esse objetivo, prop em-se critérios relevantes que comp em cada uma das dimens es da sustentabilidade, identificando as rela es (sistêmicas) que podem ocorrer entre os critérios durante a tomada de decis es organizacionais. Como resultado do cruzamento entre níveis de complexidade de decis es e as dimens es da sustentabilidade, obteve-se a estrutura de uma matriz de complexidade das decis es direcionadas à sustentabilidade. De caráter qualitativo, a matriz visa mostrar como o decisor ou pesquisador pode classificar as decis es consideradas relevantes e como poderá tomar decis es complexas que integrem satisfatoriamente as três dimens es da sustentabilidade.
TIPOLOGIA DOS ATRATIVOS NATURAIS NOS DESTINOS DE TURISMO NA NATUREZA NO BRASIL E IDENTIFICA O DOS SEUS COMPONENTES BIOFíSICOS, ATRAVéS DO MODELO DE COMPOSI O VISUAL DA PAISAGEM
Paulo dos Santos Pires,Beatiz Moscheta Welter
Revista Brasileira de Ecoturismo , 2011,
Abstract: O turismo na natureza e no seu bojo o ecoturismo, enquanto paradigma de sustentabilidade, desde meados da década de 1990 tornaram-se pujantes segmentos do turismo tanto em nível mundial como no Brasil, país que com sua notável biodiversidade e profus o de ecossistemas, desponta neste cenário com uma amplitude de recursos e paisagens naturais de reconhecido potencial para suprir a crescente demanda doméstica e internacional voltada para estes segmentos. A constata o deste potencial se assenta em uma base ecológica constituída por sete grandes ecossistemas, os Biomas, além das áreas de transi o entre eles. Já em escala regional, os Biomas podem ser reconhecidos em 49 Ecorregi es, cuja escala de mapeamento favorece o planejamento regional do turismo. Por outro lado, percebe-se que em escala mais localizada, ao nível dos destinos, ainda n o há uma referência de sistematiza o das informa es sobre os atrativos naturais e suas respectivas paisagens, plenamente aceita e utilizada especialmente na operacionaliza o do turismo em áreas naturais. é neste contexto o artigo trata da tipologia dos recursos naturais e atrativos relacionados nos destinos de turismo na natureza no Brasil, com ênfase na identifica o dos seus componentes biofísicos. Para tanto, realizou-se uma abordagem, sobretudo, qualitativa, complementada por tratamento quantitativo, utilizando-se dados de natureza primária que foram coletados junto a diversas fontes de informa o disponíveis, referentes a uma amostra n o probabilística de 56 operadoras atuantes no segmento do turismo na natureza e do ecoturismo, com sede na Grande S o Paulo, Brasília e capitais dos Estados do Rio Grande do Sul, Paraná, Minas Gerais, Rio de Janeiro e Bahia. Para o processamento e sistematiza o destes dados, adotaram-se dois modelos, sendo um de composi o visual das paisagens e outro de classifica o dos atrativos turísticos. A análise de conteúdo dos dados compilados e sistematizados resultou, primeiramente, em uma proposta de identifica o e descri o dos componentes naturais dos destinos de turismo na natureza com base na composi o visual de suas paisagens, exemplificada em três destinos preferenciais deste segmento. Em seguida, apresenta-se um quadro síntese da tipologia dos recursos naturais e atrativos correspondentes, associados aos respectivos Biomas, com maior ocorrência nos 45 destinos identificados como os de maior oferta nestes segmentos de mercado e, portanto, com representatividade nacional. Com isso, acredita-se que além de uma possível contribui o metodológica para a pesquisa acadêmica em turism
