Conhecimentos, habilidades e atitudes: o conceito de compet??ncias no trabalho e seu uso no setor p??blico

Este estudo tem dois objetivos: revisar criticamente a produ????o cient??fica nacional sobre o tema ???compet??ncias no trabalho e nas organiza????es???; e apresentar o conceito e discutir sua utiliza????o no setor p??blico. Para tanto foram analisados relatos de pesquisa emp??rica e ensaios nacionais e estrangeiros ??? em peri??dicos de psicologia e administra????o. Foram discutidos: enfoques te??ricos, instrumentos de coleta de dados, procedimentos de an??lise, entre outros aspectos. Na an??lise da produ????o nacional, constatou-se que, em sua maioria, as pesquisas: descrevem compet??ncias ocupacionais ou profissionais; possuem desenho survey; apresentam pluralidade quanto ?? natureza da pesquisa e utiliza????o de m??todos e t??cnicas para coleta e an??lise de dados; e s??o realizadas principalmente no setor terci??rio da economia. Verificou-se, ainda, a converg??ncia do conceito de compet??ncia, diante da complexidade e fragmenta????o te??rica previamente constatadas na literatura. Entretanto, mesmo em evid??ncia, a produ????o cient??fica brasileira sobre o tema ?? recente e ainda h?? uma lacuna sobre a discuss??o do construto e sua aplica????o no setor p??blico, em especial no caso brasileiro, quando se trata da administra????o p??blica federal, direta, aut??rquica e fundacional.

Tecnologia assistiva e computacional : contribuições para o atendimento educacional especializado e desafios na formação de professores

Neste trabalho, analisamos aspectos relacionados a como a tecnologia computacional é utilizada no Atendimento Educacional Especializado (AEE) e como se deu a formação de professores para utilizar esses recursos. Para tanto, delimitamos os seguintes objetivos específicos: investigar a utilização da tecnologia assistiva (TA) computacional no âmbito das salas de recursos multifuncionais (SRM); problematizar as tensões, dificuldades e possibilidades relacionadas à TA com ênfase na tecnologia computacional para o AEE; analisar a formação do professor de educação especial para o AEE tendo como recurso a TA com ênfase na tecnologia computacional, visando à mediação dos processos de aprendizagem. O aporte teórico deste trabalho foi a abordagem histórico-cultural, tomando por referência os estudos de Vigotski e seus colaboradores. Trata-se de uma pesquisa qualitativa que fez uso de diferentes instrumentos metodológicos como, os grupos focais, o questionário online e a entrevista semiestruturada. Para desenvolvê-lo, realizamos a coleta de dados em diferentes contextos, começando pelos grupos focais da pesquisa inaugural do Oneesp, que serviram como dispositivo para esta pesquisa, seguida da aplicação de um questionário aos professores participantes da pesquisa-formação desenvolvida como um desdobramento no estado do Espírito Santo da pesquisa inaugural do Oneesp pelos integrantes do Oeeesp e da aplicação in loco de entrevistas semiestruturadas com professores de educação especial, de uma SRM do Tipo II. Foram oitenta e nove professores participantes na pesquisa do Oneesp, trinta professores na pesquisa-formação do Oeeesp e dois professores para aplicação da entrevista semiestruturada in loco, respectivamente. Esses dois professores participaram tanto da pesquisa do Oneesp como da pesquisa do Oeeesp. Analisamos esses três momentos, dos quais emergiram os apontamentos que nos proporcionaram pensar, com base nas narrativas orais e escritas dos professores: sua formação para uso da TA computacional; seu entendimento sobre sua formação para este fim; seus anseios por uma formação mais direcionada; a forma como utilizam a tecnologia na sala de recursos; seus entendimentos sobre as dificuldades e possibilidades relacionadas a TA com ênfase na tecnologia computacional para o AEE. Após essas análises, concluímos que poucos professores que atuam nas SRM tiveram uma formação que possibilitasse a aplicação das tecnologias computacionais em sua mediação pedagógica, aliando teoria e prática, com momentos de formação que privilegiassem os momentos presenciais e em laboratórios, onde possam interagir com os computadores e suas ferramentas simbólicas. Sem essa familiaridade com os recursos computacionais, os professores acabam sentindo-se inseguros para utilizá-los, deixando de potencializar, pela via desses recursos, os processos de ensinoaprendizagem do aluno com deficiência. Faz-se necessário um investimento nesse tipo de formação e, mais do que isso, que se viabilize para os professores que atuam ou que pretendem atuar nas SRM. A partir de uma formação apropriada é possível fazer com que os professores utilizem os recursos computacionais como mediadores dos processos de ensino-aprendizagem de seus alunos.

No-till corn performance in response to P and fertilization modes

No-tillage systems provide soil changes that affect nutrient dynamics, hence, changing rates and forms of fertilizer application. This study aimed to evaluate the effect of phosphorus (P) and modes of nitrogen (N) and P application in corn under long-term no-tillage in a clayey Oxisol. Two experiments were carried out in the same experimental area and in the same year, in a randomized blocks design with four replications. In experiment I, the treatments consisted of five doses of phosphorus (0, 40, 80, 120 and 160 kg ha-1 of P2O5) applied in the sowing furrow. In experiment II, the treatments consisted of the N and P application modes (topdressing, in the sowing furrow and control - without N and P). Experiment I evaluated the root length, P uptake and grain yield and, the Experiment II, the firing height and yield. The P rates provided linear increases in root length in the 0-10 cm layer, P uptake and grain production. The different modes of application provided differences in the firing height and corn yield. The control treatment (0 kg ha-1 of N and P) provided the highest firing height, superior than those of topdressing and application in the furrow, which were not significantly different. The topdress application of N and P provided an increase in corn yield that exceeded 16 and 42% of the application in the furrow and the control, respectively. Thus, the results confirmed that increasing rates of P2O5, in soil with high initial P content, influence positively corn production factors, but with little significant responses, and the topdress application of N and P on soil with high P content, without water restriction, provided increased grain yield in relation to the application in the furrow.

Effects of growth reducer and nitrogen fertilization on morphological variables, SPAD index, interception of radiation and productivity of wheat

ABSTRACT The objective of this study was to evaluate the effect of growth reducer and nitrogen fertilization on morphological variables, SPAD index, radiation interception, and grain yield of three cultivars of wheat. The experimental design was a randomized block in factorial scheme 3x5x2, with three cultivars (Mestre, Iguaçú and Itaipú), five nitrogen doses (0, 40, 80, 120, 160 Kg ha-1), and application or no application of a growth reducer, with three replications. The following characteristics were evaluated: plant height, SPAD index, leaf area index (LAI), Global Radiation Interception (GRI) and grain yield. The Tukey test (p < 0.05) was used for the comparison between the means of cultivar and growth reducer factors, and for a regression analysis to evaluate N levels. Increasing the dose of nitrogen promotes an increase in LAI of plants of wheat crops differently among cultivars, which leads to a greater degree of global radiation interception. At doses higher or equal to 120 Kg ha-1 of nitrogen, there are significant differences in grain yield between treatments with and without the application of the growth reducer. The significant interaction between growth reducer and nitrogen dose, showed that applications of growth reducer increase the GRI at doses above and below 80 Kg ha-1 of nitrogen. Nitrogen rates of 138 and 109 Kg ha-1 are responsible for maximum grain yields of wheat, which is 4235 and 3787 Kg ha-1 with and without the use of growth reducer, respectively.

Pediculus capitis infestation according to sex and social factors in Argentina

OBJECTIVE: To determine the intensity of Pediculus capitis infestation (abundance) among Argentinean schoolchildren. Children's sex and social stratum were analyzed as modifiers of the general prevalence and degree of parasitism. METHODS: The study included 1,370 schoolchildren (692 girls, 678 boys) from 26 schools of the province of La Rioja (21 public schools, five private schools). Classic prevalence was obtained as the percentage of children with nits and/or lice. Moreover, five degrees of parasitism were classified: 0) children with no signs of pediculosis; 0+) children with evidence of past infestation; 1) children with a recent infestation and low probability of active parasitism; 2) children with a recent infestation and high probability of active parasitism; 3) children with mobile lice (active pediculosis). RESULTS: The general prevalence was 61.4% (girls: 79%; boys: 44%, p<0.001). Private schools showed lower prevalence than public schools (p=0.02), especially due to the low prevalence in boys. Fifty percent of children were classified in classes 0 and 0+, 22% in class 1; and 28% in grades 2 and 3. The proportion of children in grade 3 was higher in public schools than in private schools. There were significant sexual differences in the intensity of parasitism for grades 2 and 3, where girls' rates exceeded twice those of boys'. CONCLUSIONS: Sex and social stratum are important modifiers of P. capitis general prevalence and degree of infestation. The classification of children by intensity of infestation allowed a more precise delimitation of this condition, which is especially important for disease surveillance and application of control measures.

Controllability results for impulsive mixed type functional integro-differential evolution equations with nonlocal conditions

In this paper, we establish the controllability for a class of abstract impulsive mixed-type functional integro-differential equations with finite delay in a Banach space. Some sufficient conditions for controllability are obtained by using the Mönch fixed point theorem via measures of noncompactness and semigroup theory. Particularly, we do not assume the compactness of the evolution system. An example is given to illustrate the effectiveness of our results.

A power line communication stack for metering, SCADA and large-scale domotic applications

This paper describes the communication stack of the REMPLI system: a structure using power-lines and IPbased networks for communication, for data acquisition and control of energy distribution and consumption. It is furthermore prepared to use alternative communication media like GSM or analog modem connections. The REMPLI system provides communication service for existing applications, namely automated meter reading, energy billing and domotic applications. The communication stack, consisting of physical, network, transport, and application layer is described as well as the communication services provided by the system. We show how the peculiarities of the power-line communication influence the design of the communication stack, by introducing requirements to efficiently use the limited bandwidth, optimize traffic and implement fair use of the communication medium for the extensive communication partners.

Wind resource modelling in complex terrain using different mesoscale–microscale coupling techniques

Wind resource evaluation in two sites located in Portugal was performed using the mesoscale modelling system Weather Research and Forecasting (WRF) and the wind resource analysis tool commonly used within the wind power industry, the Wind Atlas Analysis and Application Program (WAsP) microscale model. Wind measurement campaigns were conducted in the selected sites, allowing for a comparison between in situ measurements and simulated wind, in terms of flow characteristics and energy yields estimates. Three different methodologies were tested, aiming to provide an overview of the benefits and limitations of these methodologies for wind resource estimation. In the first methodology the mesoscale model acts like “virtual” wind measuring stations, where wind data was computed by WRF for both sites and inserted directly as input in WAsP. In the second approach, the same procedure was followed but here the terrain influences induced by the mesoscale model low resolution terrain data were removed from the simulated wind data. In the third methodology, the simulated wind data is extracted at the top of the planetary boundary layer height for both sites, aiming to assess if the use of geostrophic winds (which, by definition, are not influenced by the local terrain) can bring any improvement in the models performance. The obtained results for the abovementioned methodologies were compared with those resulting from in situ measurements, in terms of mean wind speed, Weibull probability density function parameters and production estimates, considering the installation of one wind turbine in each site. Results showed that the second tested approach is the one that produces values closest to the measured ones, and fairly acceptable deviations were found using this coupling technique in terms of estimated annual production. However, mesoscale output should not be used directly in wind farm sitting projects, mainly due to the mesoscale model terrain data poor resolution. Instead, the use of mesoscale output in microscale models should be seen as a valid alternative to in situ data mainly for preliminary wind resource assessments, although the application of mesoscale and microscale coupling in areas with complex topography should be done with extreme caution.

Conceiving modern engineers within the framework of the sustainability action plan (PASUS) of ISEP: sustainability matters!

Engineering education practices have evolved not only due to the natural changes in the contents of the curricula and skills but also, and more recently, due to the requirements imposed by the Bologna revision process. In addition, industry is becoming more demanding, as society is becoming more and more aware of the global needs and consequences of industrial practices. Under this scope, higher education needs not only to follow but also to lead these trends. Therefore, the School of Engineering of the Polytechnic Institute of Porto (ISEP), a Global Reporting Initiative (GRI) training partner in Portugal, prepared and presented its Sustainability Action Plan (PASUS), with the main objective of creating a new kind of engineers, with Sustainable Development at the core of their graduation and MsC degrees. In this paper, the main strategies and activities of the referred plan along with the strategic approach, which guided its development and implementation, will be presented in detail. Additionally, a reflection about the above mentioned bridge between concept and application will be established and justified, in the framework of the action plan. Although in most of the situations, there was no prior discussion or specific request, many of the graduation and post-graduation programmes offered by ISEP already include courses that attend to PASUS philosophy. As a consequence, the number of Master thesis, Graduation projects and R&D projects that address sustainability problems has grown substantially, a proof that for ISEP community, sustainability really matters!
