Comparative Genetic Diversity of Wild and Captive Populations of the Bare-Faced Curassow (Crax fasciolata) Based on Cross-Species Microsatellite Markers: Implications for Conservation and Management

The bare-faced curassow (Crax fasciolata) is a large Neotropical bird that suffers anthropogenic pressure across much of its range. A captive population is maintained for conservation management, although there has been no genetic screening of stocks. Based on the six microsatellite markers developed for Crax globulosa, the genetic variability of C. fasciolata and possible differences between a wild and a captive population were investigated. Only three loci were polymorphic, with a total of 27 alleles. More than half of these alleles were private to the wild (n = 8) or captive (n = 7) populations. Significant deviations from Hardy-Weinberg equilibrium were restricted to the captive population. Despite the number of private alleles, genetic drift has probably promoted differentiation between populations. Our results indicate that wild C. fasciolata populations are genetically impoverished and structured, but species-specific microsatellite markers will be necessary for a more reliable assessment of the species` genetic diversity.

Russian Arctic Ports : Problems with the development and management of tourist flows

The potential changes to the territory of the Russian Arctic open up unique possibilities for the development of tourism. More favourable transport opportunities along the Northern Sea Route (NSR) create opportunities for tourism development based on the utilisation of the extensive areas of sea shores and river basins. A major challenge for the Russian Arctic sea and river ports is their strong cargo transport orientation originated by natural resource extraction industries. A careful assessment of the prospects of current and future tourism development is presented here based on the development of regions located along the shores of the Arctic ocean (including Murmansk and Arkhangelsk oblast, Nenets Autonomous okrug (AO), Yamal-Nenets AO, Taymyr AO, Republic of Sakha, Chykotsky AO). An evaluation of the present development of tourism in maritime cities suggests that a considerable qualitative and quantitative increase of tourism activities organised by domestic tourism firms is made virtually impossible. There are several factors contributing to this. The previously established Soviet system of state support for the investments into the port facilities as well as the sea fleet were not effectively replaced by creation of new structures. The necessary investments for reconstruction could be contributed by the federal government but the priorities are not set towards the increased passenger transportation. Having in mind, increased environmental pressures in this highly sensitive area it is especially vital to establish a well-functioning monitoring and rescue system in the situation of ever increasing risks which come not only from the increased transports along the NSR, but also from the exploitation of the offshore oil and gas reserves in the Arctic seas. The capacity and knowledge established in Nordic countries (Norway, Finland) concerning cruise tourism should not be underestimated and the already functioning cooperation in Barents Region should expand towards this particular segment of the tourism industry. The current stage of economic development in Russia makes it clear that tourism development is not able to compete with the well-needed increase in the cargo transportation, which means that Russia’s fleet is going to be utilised by other industries. However, opening up this area to both local and international visitors could contribute to the economic prosperity of these remote areas and if carefully managed could sustain already existing maritime cities along the shores of the Arctic Ocean.

Private or public? a taxonomy of optimal ownership and management regimes

We develop a theory of public versus private ownership based on value diversion by managers. Government is assumed to face stronger institutional constraints than has been assumed in previous literature. The model which emerges from these assumptions is fexible and has wide application. We provide amapping between the qualitative characteristics of an asset, its main use - including public goods characteristics, and spillovers toother assets values - and the optimal ownership and management regime. The model is applied to single and multiple related assets. We address questions such as; when is it optimal to have one of a pair ofr elated assets public and the other private; when is joint management desirable; and when should a public asset be managed by the owner of a related private asset? We show that while private ownership can be judged optimal in some cases solely on the basis of qualitative information, the optimality of any other ownership and management regimes relies on quantitative analysis. Our results reveal the situations in which policy makers will have difficulty in determining the opimal regime.

The gay subject in business and its discursive formation: an exploration on power, knowledge and sexuality

Issues related to the reality of lesbian, gay, bisexual and transgender (LGBT) individuals are being incorporated into institutional and social discourses, and show the challenges that must be overcome towards citizenship. The inclusion of gay rights in the domain of institutions like the United Nations and the Brazilian Secretariat of Human Rights are a response to broader movements that places the gay subject as an important topic of debate in the social-political sphere. In this scenario, some institutions deserve close attention from researchers related to gay issues, the business environment being a good example. In this domain, diversity has become an important topic of debate between scholars, where the question of sexual identity in most cases does not appear. The literature that actually focuses on the theme is explored through approaches that are not able to break with universalisms and a normatized vocabulary. Therefore, this research explores discursive structures related to sexuality and examines the meanings construed throughout these structures as described by gay individuals working in business. Furthermore, it investigates patterns of discursive normative structures and consequential challenges faced by gay people in the working environment, and also complements the current debate both in the socio-political sphere and in academic reality on LGBT challenges. The Foucauldian notions of discourse, knowledge and power, and the main concepts of queer theory are incorporated to the analysis, as well as concepts related to the politics of post-colonial sexuality, subordination, and hegemonic forces, together with role of reflexivity in modernity and its impacts on secularized mental structures. The research design takes a phenomenological approach and bases its knowledge claim on a participatory perspective, where the sample chosen for data collection consisted of gay individuals working in the business environment, aiming at generate categories of meanings through the description of their experiences.

Impactos da adoção das novas tecnologias BPM (business process management) nos processos governamentais

Este relatório consolida os trabalhos de pesquisa, desenvolvidos entre abril de 2005 e abril de 2006, sobre o estado de adoção e oportunidades para uso de novas tecnologias de informação em processos de governo. A ampliação de fronteiras, para além dos limites tradicionais das organizações, traz uma nova e mais forte demanda por flexibilidade que possibilite o tratamento integrado de organismos de diferentes constituições, arquiteturas e processos operacionais, sem falar nos diferentes sistemas de informações. Isto é ainda mais importante nas organizações públicas. Por outro lado, uma das principais características negativas dos órgãos públicos é a morosidade e a burocracia nos processos administrativos e de atendimento ao cidadão. A falta de uma visão tecnológica moderna, isto é, a falta de um Plano Diretor de Tecnologia da Informação (PDTI) voltada para novas soluções, como é o caso do BPM, alinhada à falta de integração entre os sistemas e processos, faz com que muitos órgãos governamentais estejam caminhando na contramão do desenvolvimento tecnológico. Este projeto de pesquisa reveste-se, portanto, de alto interesse, pois focaliza as possibilidades e impactos da adoção das novas tecnologias orientadas a processos e web services (BPM - Business Process Management e BPMS - Business Process Management Systems) na área governamental, bastante desprovida de soluções integradas de serviços aos cidadãos e empresas. Estas novas tecnologias trazem paradigmas completamente diferentes dos até aqui adotados na implementação de sistemas de informações e automação de processos. Apesar das dificuldades inerentes ao tratamento de um tema complexo e novo, mais ainda em organismos governamentais, acreditamos ter desenvolvido um trabalho bastante aprofundado, atendendo aos objetivos estabelecidos no plano original, com os necessários acertos de rota e foco dos trabalhos. Cremos, também, que este trabalho estabelece uma referência relevante no conhecimento relacionados à melhoria de processos de governo, com base em novas tecnologias. Como sub-produtos planejados e realizados, inseridos no caderno de anexos a este relatório, estão conteúdos já desenvolvidos para a edição um ou dois livros sobre o tema, diversos artigos produzidos, além de diversos eventos realizados na EAESP, envolvendo o tema do projeto, que proporcionaram a oportunidade de excelentes trocas de experiências. Este relatório, apresentado de forma objetiva e sintética, focalizando somente os principais aspectos tratados, é complementado por um extenso conteúdo complementar, entregue em um caderno de Anexos.

Growth process in business and social entrepreneurship: the case of Brazil

The purpose of the dissertation is to investigate in depth the difference between the challenges social and business entrepreneurs face in the growth phase of their business in the particular environment of Brazil. This objective has been achieved through a two-steps methodology. The first step is a set of in-depth interviews carried out with industry experts such as professors, venture capitalists, consultants, fund managers or people involved in the support of growing startups (i.e. accelerators). These interviews allowed, first, to build a general perspective on the environment entrepreneurs operate into and to identify a list of challenges entrepreneurs face in the growth process of their business. This list was completed with the additional challenges identified in the previous literature. The second step of the methodology was to test the relevance of these challenges in the mind and experience of social and traditional entrepreneurs. A questionnaire was then submitted to 145 social and 286 traditional entrepreneurs. The results were statistically analyzed to test the relative relevance of these challenges for one group of entrepreneurs with respect to the other. The outcome of the analysis was significant. The most relevant challenges identified were, for both groups, taxation, bureaucracy, finding the right employees, creating effective teams, measuring firm performance and social value creation and obtaining funds. On the other side motivation, innovation, competition and lack of market space for growth represented the least relevant issues in the minds of entrepreneurs. This rank however did not differ significantly from social to traditional entrepreneurs. This testifies that in Brazil social and traditional entrepreneurs face the same set of challenges despite the widespread belief of the opposite.

Analise das melhores práticas em business process management: estudo de casos em organizações hospitalares de Natal/RN

O gerenciamento dos processos organizacionais vem sendo estudado pela ciência administrativa como forma de romper com o paradigma da estrutura organizacional funcional através da Gestão por Processos. O Business Process Management ( BPM alinhado às estratégias organizacionais e suportado cada vez mais pela Tecnologia da Informação (TI), proporciona clareza nas diversas pontas do processo colaborando para sua melhoria contínua com o objetivo de gerar valor agregado ao cliente. As organizações de saúde estão entre as empresas prestadoras de serviço pouco estudadas em relação ao gerenciamento por processos. Assim, este estudo analisou por meio de um estudo empírico de natureza qualitativa, como estão sendo conduzidos os processos organizacionais hospitalares à luz das melhores práticas em BPM. A pesquisa foi realizada através do estudo de casos múltiplos realizados em duas organizações hospitalares na cidade de Natal/RN. A literatura de referência apresentou diversos fatores para um desempenho otimizado em BPM, tratados nesta pesquisa como as melhores práticas em BPM. A partir da revisão da literatura foi elaborada uma síntese das melhores práticas de BPM que serviu de base para elaboração do modelo da pesquisa utilizado para coleta e análise dos dados. Este modelo indicou onze categorias que foram utilizadas para elaboração do roteiro de estrevistas semi-estruturadas, através da técnica de análise de conteúdo, com categorização de grade fechada. As categorias foram agrupadas em duas dimensões: Elementos relacionados à gestão ( governança ; liderança , alinhamento estratégico , cultura e conhecimento ) e elementos relacionados aos processos ( desenho , responsável , executores , tecnologia da informação e indicadores ), e ainda foi identificada uma terceira categoria: escritório de processos . Para seleção dos sujeitos desta pesquisa foi adotada a estratégia em cadeia ou bola de neve . Foi possível identificar que todas as categorias apontadas no modelo de pesquisa emergem entre os fatores buscados pelas organizações hospitalares para o gerenciamento por processos com destaque para categorias: cultura ; conhecimento ; desenho ; tecnologia da informação e indicadores . Em complemento às categorias de análise, foram identificadas dificuldades relacionadas à comunicação e integração dos diversos elos do processo. Além disso, constatou-se que nos hospitais investigados há um desvio do conceito de BPM no que diz respeito a seu objetivo final: agregar valor ao cliente. A pesquisa concluiu que o gerenciamento por processos nas organizações hospitalares investigadas encontra-se em fase inicial ou em desenvolvimento, sendo necessário superar as barreiras da comunicação e edificar uma cultura organizacional orientada às necessidades dos clientes para aplicação das melhores práticas de BPM, desta forma pesquisas futuras sobre este tema em outras organizações hospitalares, podem facilitar um estudo comparativo e ampliar o conhecimento no assunto

Effects of plant densities and management of purple nutsedge on sugarcane yield and effect of growth stages and main way of herbicides contact and absorption on the control of tubers

Field experiments carried out with Cyperus rotundus L. at low (58-246), medium (318773), and high (675-1198 shoots/m(2)) densities showed sugarcane yield reductions of 13.5, 29.3, and 45.2%, respectively in relation to the control. In the second field experiment, the integration of a mechanic method with two sequences of plowing and disking operations in the dry season, and complementary applications of trifloxysulfuron-sodium + ametrine and sulfentrazone (rainy season) was studied. Average of the chain connected to original shoot showed 92, 95, and 65% of reduction with trifloxysulfuron-sodium + ametrine and surfactant, at the application stages early, preflowering, and full flowering, respectively.

The black lion tamarin Leontopithecus chrysopygus - its conservation and management

The black lion tamarin Leontopithecus chrysopygus originally occurred throughout a large part of the Atlantic forest in the west of the state of São Paulo, Brazil. Today, however, it is restricted to a few isolated forest fragments as a result of deforestation caused by cattle ranching, and urban and agricultural expansion, especially in this century. One of its last strongholds is a small gallery forest at Lencois Paulista in the west-central part of the state. The authors report on a long-term study of this small and isolated population, aimed particularly at providing a basis for the intensive management and conservation of the species and its habitat.

Dental fluorosis: Exposure, prevention and management

Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. The severity of dental fluorosis depends on when and for how long the overexposure to fluoride occurs, the individual response, weight, degree of physical activity, nutritional factors and bone growth. The risk period for esthetic changes in permanent teeth is between 20 and 30 months of age. The recommended level for daily fluoride intake is 0.05 - 0.07 mg F/Kg/day, which is considered of great help in preventing dental caries, acting in remineralization. A daily intake above this safe level leads to an increased risk of dental fluorosis. Currently recommended procedures for diagnosis of fluorosis should discriminate between symmetrical and asymmetrical and/or discrete patterns of opaque defects. Fluorosis can be prevented by having an adequate knowledge of the fluoride sources, knowing how to manage this issue and therefore, avoid overexposure.

Design and management optimization of trickle irrigation systems using non-linear programming

A non-linear model is presented which optimizes the lay-out, as well as the design and management of trickle irrigation systems, to achieve maximum net benefit. The model consists of an objective function that maximizes profit at the farm level, subject to appropriate geometric and hydraulic constraints. It can be applied to rectangular shaped fields, with uniform or zero slope. The software used is the Gams-Minos package. The basic inputs are the crop-water-production function, the cost function and cost of system components, and design variables. The main outputs are the annual net benefit and pipe diameters and lengths. To illustrate the capability of the model, a sensitivity analysis of the annual net benefit for a citrus field is evaluated with respect to irrigated area, ground slope, micro-sprinkler discharge and shape of the field. The sensitivity analysis suggests that the greatest benefit is obtained with the smallest microsprinkler discharge, the greatest area, a square field and zero ground slope. The costs of the investment and energy are the components of the objective function that had the greatest effect in the 120 situations evaluated. (C) 1996 Academic Press Limited
