Homens idosos em programas de esporte e lazer

O cotidiano dos projetos sociais sobre esporte e lazer revela grupos de participantes que se identificam com as atividades lá desenvolvidas. Por outro lado, há pessoas avessas às atividades dos projetos, porque normalmente alguma característica as deixa desconfortáveis. Considerando essa realidade, o estudo procurou identificar os fatores que interferem na participação de homens idosos em programas de esporte e lazer. O estudo foi aplicado no bairro de Piedade, zona norte da cidade do Rio de Janeiro, onde foram entrevistados 10 idosos que residem próximo do projeto SUDERJ em FORMA. Para a coleta, processamento e apresentação dos dados utilizamos a abordagem radical das representações sociais proposta por Votre (2009), a partir do Discurso do Sujeito Coletivo (DSC) de Lefebvre et al (2007). O modelo de análise delineado valoriza tanto as pessoas individuais, em suas falas singulares, quanto a reunião dessas pessoas, que falam como grupo sobre tópicos que lhes são relevantes. Os resultados obtidos apontam que os fatores que contribuem para a ausência dos homens idosos nas atividades desenvolvidas pelo projeto são: a figura do professor e o método por ele aplicado; receio, vergonha e discriminação, em participar com mulheres e jovens; gosto por outras práticas não oferecidas pelo projeto. Embora toda a boa premissa relacionada aos benefícios da participação dos idosos em programas de esporte e lazer e perante a garantia de acesso a estes programas, no estudo ficou constatado que tais condições não são suficientes para atingir o público masculino de idosos. Consideramos que no processo de criação de novas estratégias e propostas de intervenção, é de extrema importância que ocorra um planejamento cuidadoso que identifique as dificuldades sociais e individuais que reduzam ou impeçam a participação do sujeito idoso nas atividades propostas. Concluímos, também, que reforçar os benefícios da prática da atividade física, oferecer atividades de lazer não ligadas à prática esportiva, oferecer atividades adaptadas e atividades exclusivas para os homens, são alternativas viáveis para atrair o homem idoso para o projeto.

O impacto do ativo intangível medido pelo efeito da inovação organizacional em instituição pública multipropósito: o caso do Instituto Nacional de Infectologia Evandro Chagas - INI da Fiocruz

Esta dissertação foi desenvolvida no Instituto Nacional de Infectologia Evandro Chagas (INI) da Fundação Oswaldo Cruz (Fiocruz), uma organização pública multipropósito de saúde com atividades de pesquisa, assistência e ensino, que adotou a estratégia de inovar a sua estrutura organizacional, com vistas a garantir a qualidade dos serviços prestados à população, bem como reforçar a orientação empreendedora das suas ações integradas. Sob o ponto de vista da pesquisa em Ciências Contábeis, a reestruturação do INI constitui um exemplo potencial da acumulação de ativo intangível pela organização e este foi o fato gerador do problema da pesquisa: a aplicação do método DEA para avaliar a melhoria da eficiência dos oito laboratórios de pesquisa multipropósito do INI, está associada ao referencial teórico que justifica a inovação organizacional implantada no Instituto após proposta nos Congressos Internos da Fiocruz? O objetivo geral foi analisar os resultados dos escore-sínteses do Data Envelopment Analysis (DEA), como medida dos ativos intangíveis, associando-os aos efeitos provenientes da implantação de mudanças organizacionais estratégicas, caracterizadas como inovações organizacionais ocorridas nos oito laboratórios de pesquisa clínica multipropósitos, isto é, que contemplam ensino, pesquisa e assistência, no INI da Fiocruz. O método consistiu de quatro etapas. Na primeira, foi realizada a análise da literatura sobre ativos intangíveis; inovação organizacional; estruturas da organização e modelo de análise de eficiência em organizações. Na segunda, foi realizada a coleta dos indicadores qualitativos referentes a mudança da estrutura organizacional de oito laboratórios do INI por meio de análise documental dos Congressos Internos da Fiocruz e uma pesquisa de opinião dos representantes dos laboratórios; quantitativamente, foram levantados dados para calcular o indicador de eficiência de cada um dos laboratórios. Na terceira etapa foi realizada a análise dos dados coletados, do período de 2006-2012, utilizando os indicadores calculados para associar a eficiência do conjunto destas atividades antes e depois da inovação organizacional associada à adoção de uma estrutura inovadora na reestruturação. Finalmente, a quarta etapa apresentou os resultados e as respectivas considerações sobre a pesquisa. Como contribuição, apresenta-se uma associação entre a inovação organizacional, decorrente da reestruturação dos oito laboratórios de pesquisa clínica e os resultados do método empírico que utiliza o DEA.

Description and growth of larval and pelagic juvenile pygmy rockfish (Sebastes wilsoni) (family Sebastidae)

A developmental series of larval and pelagic juvenile pygmy rockfish (Sebastes wilsoni) from central California is illustrated and described. Sebastes wilsoni is a non- commercially, but ecologically, important rockfish, and the ability to differentiate its young stages will aid researchers in population abundance studies. Pigment patterns, meristic characters, morphometric measurements, and head spination were recorded from specimens that ranged from 8.1 to 34.4 mm in standard length. Larvae were identified initially by meristic characters and the absence of ventral and lateral midline pigment. Pelagic juveniles developed a prominent pigment pattern of three body bars that did not extend to the ventral surface. Species identification was confirmed subsequently by using mitochondrial sequence data of four representative specimens of various sizes. As determined from the examination of otoliths, the growth rate of larval and pelagic juvenile pygmy rockfish was 0.28 mm/day, which is relatively slow in comparison to the growth rate of other species of Sebastes. These data will aid researchers in determining species abundance.

Characterisation of technology roadmaps: Purpose and format

A report on characterisation of technology roadmaps, its purpose and formats are presented. A fast-start process is developed to support the initiation of technology roadmapping in firms to address the industrial needs. The purpose of each roadmap is related to a number of planning aims: product, capability, integration, strategic, long-range, programme and process planning. The second set of categories are related to the format of the roadmap, based on observed structure: multiple or single layers, bars, tables, graphs, pictorial forms, flow diagrams and text. It is concluded that technology roadmaps processes a great potential for supporting the development and implementation of business product and technology strategy.

Development of blade profiles for low pressure turbine applications

This paper describes a program of work, largely experimental, which was undertaken with the objective of developing an improved blade profile for the low-pressure turbine in aero-engine applications. Preliminary experiments were conducted using a novel technique. An existing cascade of datum blades was modified to enable the pressure distribution on the suction surface of one of the blades to be altered. Various means, such as shaped inserts, an adjustable flap at the trailing edge, and changing stagger were employed to change the geometry of the passage. These experiments provided boundary layer and lift data for a wide range of suction surface pressure distributions. The data was then used as a guide for the development of new blade profiles. The new blade profiles were then investigated in a low-speed cascade that included a set of moving bars upstream of the cascade of blades to simulate the effect of the incoming wakes from the previous blade row in a multistage turbine environment.

An experimental semi-active anti-roll system

The use of anti-roll bars to provide additional roll stiffness and therefore to reduce the trade-off between ride and rollover performance has previously been studied. However, little work has been carried out to investigate the benefits of a switchable roll stiffness. Such a semi-active anti-roll system has the ability to have a low roll stiffness during straight-ahead driving for improved ride performance and high roll stiffness during cornering for improved roll performance. Modelling of such a system is conducted and the model is validated against a semi-active anti-roll system fitted to an experimental vehicle. Experimental and theoretical investigations are used to investigate the performance of such a system with several different strategies employed to switch to the high-stiffness state. The use of an air suspension on the vehicle to roll into corners is also investigated, as is the possibility of exploiting the road layout by allowing the vehicle to be in a low-roll-stiffness configuration during a corner, and then to switch to the high-roll-stiffness configuration midcorner, hence 'locking in' a roll angle. The best rollover performance improvement that was achieved was 12.5 per cent. © IMechE 2008.

Demodulation as probabilistic inference

Demodulation is an ill-posed problem whenever both carrier and envelope signals are broadband and unknown. Here, we approach this problem using the methods of probabilistic inference. The new approach, called Probabilistic Amplitude Demodulation (PAD), is computationally challenging but improves on existing methods in a number of ways. By contrast to previous approaches to demodulation, it satisfies five key desiderata: PAD has soft constraints because it is probabilistic; PAD is able to automatically adjust to the signal because it learns parameters; PAD is user-steerable because the solution can be shaped by user-specific prior information; PAD is robust to broad-band noise because this is modeled explicitly; and PAD's solution is self-consistent, empirically satisfying a Carrier Identity property. Furthermore, the probabilistic view naturally encompasses noise and uncertainty, allowing PAD to cope with missing data and return error bars on carrier and envelope estimates. Finally, we show that when PAD is applied to a bandpass-filtered signal, the stop-band energy of the inferred carrier is minimal, making PAD well-suited to sub-band demodulation. © 2006 IEEE.

Paracobitis nanpanjiangensis, a new loach (Balitoridae: Nemacheilinae) from Yunnan, China

A new species of the genus Paracobitis, Paracobitis nanpanjiangensis is described from tributaries of the Nanpanjiang River drainage in China. It is distinguished from its congeners, except P. oligolepis and P. wujiangensis, by body scaleless or with rudimentary scales (caudal peduncle with several deeply embedded scales). It can be differentiated from P. wujiangensis by the complete lateral line (vs. incomplete), lower dorsal crest reaching the vertical of origin of anal fin (vs. shorter and higher dorsal crest not reaching the base of anal fin). It is distinguished from P. oligolepis by the following characters: branched dorsal fin with 81/2 (a few 91/2) rays (vs. 91/2), interspaces between bars in front of dorsal fin conspicuously thinner than those behind (vs. vermiform markings), dorsal head without vermiform markings or obscure (vs. clearly vermiform markings on dorsal head), vertebrae 4 + 36-38 (vs. 4 + 39-41).

Evidence-informed development of engineering practical work: Effecting change through staff and student engagement

This paper discusses innovations in curriculum development in the Department of Engineering at the University of Cambridge as a participant in the Teaching for Learning Network (TFLN), a teaching and learning development initiative funded by the Cambridge-MIT Institute a pedagogic collaboration and brokerage network. A year-long research and development project investigated the practical experiences through which students traditionally explore engineering disciplines, apply and extend the knowledge gained in lectures and other settings, and begin to develop their professional expertise. The research project evaluated current practice in these sessions and developed an evidence-base to identify requirements for new activities, student support and staff development. The evidence collected included a novel student 'practice-value' survey highlighting effective practice and areas of concern, classroom observation of practicals, semi-structured interviews with staff, a student focus group and informal discussions with staff. Analysis of the data identified three potentially 'high-leverage' strategies for improvement: development of a more integrated teaching framework, within which practical work could be contextualised in relation to other learning; a more transparent and integrated conceptual framework where theory and practice were more closely linked; development of practical work more reflective of the complex problems facing professional engineers. This paper sets out key elements of the evidence collected and the changes that have been informed by this evidence and analysis, leading to the creation of a suite of integrated practical sessions carefully linked to other course elements and reinforcing central concepts in engineering, accompanied by a training and support programme for teaching staff.

A plane symmetric 6R foldable ring

The design of a deployable structure which deploys from a compact bundle of six parallel bars to a rectangular ring is considered. The structure is a plane symmetric Bricard linkage. The internal mechanism is described in terms of its Denavit-Hartenberg parameters; the nature of its single degree of freedom is examined in detail by determining the exact structure of the system of equations governing its movement; a range of design parameters for building feasible mechanisms is determined numerically; and polynomial continuation is used to design rings with certain specified desirable properties. © 2013 Elsevier Ltd.

Occlusive Components Analysis

We study unsupervised learning in a probabilistic generative model for occlusion. The model uses two types of latent variables: one indicates which objects are present in the image, and the other how they are ordered in depth. This depth order then determines how the positions and appearances of the objects present, specified in the model parameters, combine to form the image. We show that the object parameters can be learnt from an unlabelled set of images in which objects occlude one another. Exact maximum-likelihood learning is intractable. However, we show that tractable approximations to Expectation Maximization (EM) can be found if the training images each contain only a small number of objects on average. In numerical experiments it is shown that these approximations recover the correct set of object parameters. Experiments on a novel version of the bars test using colored bars, and experiments on more realistic data, show that the algorithm performs well in extracting the generating causes. Experiments based on the standard bars benchmark test for object learning show that the algorithm performs well in comparison to other recent component extraction approaches. The model and the learning algorithm thus connect research on occlusion with the research field of multiple-causes component extraction methods.

Design and testing of an ortho-planar micro-valve

This paper presents the production and testing of an ortho-planar one-way micro-valve. The main advantages of such valves are that they are very compact and can be made from a single flat piece of material. A previous paper presents and discusses a micro-valve assembly based on a spider spring. The present paper focuses on the valve assembly process and the valve performance.. Several prototypes with a bore of 0.2 mm have been built using two manufacturing techniques (μEDM and stereo-lithography) and tested for pressures up to 7 bars. © 2008 International Federation for Information Processing.
