Traz comentários à Lei nº 4.898, de 9 de dezembro de 1965, responsável pela regulação do direito de representação e o processo de responsabilidade administrativa civil e penal, nos casos relacionados ao tema abordado

ESTÁGIO SUPERVISIONADO E IDENTIDADE PROFISSIONAL EM SERVIÇO SOCIAL: DILEMAS E POTENCIALIDADES NO CONTEXTO CONTEMPORÂNEO

Resumo O presente trabalho traz como premissa a compreensão do Estágio Supervisionado em Serviço Social enquanto solo fértil para a construção da identidade profissional do assistente social. Objetiva problematizar como esse espaço contribui para moldar uma identidade profissional, e suas principais determinações contemporâneas. Com um levantamento bibliográfico/documental verifica-se como o Estágio se constitui em um espaço privilegiado de potencialidades e desafios. Dentre estes se apresenta a precarização dos espaços sócioocupacionais; a tendência a uma instrumentalização do Estágio; e proliferação dos estágios não-obrigatórios. Por outro lado, é ancorando-se no nosso Projeto Profissional que busca-se alternativas de enfrentamento dessa realidade

Energy expenditure and physical activity patterns in children : applicability of simultaneous methods

Consistently, reports in the literature have identified that a sedentary lifestyle contributes to the progression of a range of chronic degenerative diseases. The measurement of energy expenditure and physical activity pattern in children is a challenge for all professionals interested in paediatric health and from a broader perspective, the public health fraternity charged with considering longer term health consequences of physical inactivity. The primary objective of this thesis was to identify a suitable indirect and objective measurement technique for the assessment of energy expenditure and physical activity pattern in children. The ideal characteristics of such a technique are that it should be reproducible and have been validated against a criterion reference method. To achieve this goal, a series of methodological studies were undertaken (Chapters II and III). This work was essential to increase accuracy during the individualised laboratory calibration process and further minimise prediction errors when analysing data from 7 days of monitoring under free-living conditions in the second part of the study (Chapters IV and V). In the first study to verify the combined effect of body position, apparatus and distraction on children's resting metabolic rate (RMR), experiments were carried out on 14 children aged 8-12 (mean age = 10.1 years ± 1.4). Each participant underwent 2 test sessions, one week apart under three different situations: a) using mouthpiece and nose-clip (MN) or facemask (FM); b) sitting (SEAT) or lying (LY) and c) TV viewing (TV) or no TV viewing. In the first session, following 20 min rest and watching TV, the following protocol was used: LY: 20 min - stabilisation; 10 min using MN and 10 min using FM. Body position was then changed to seated: 20 min stabilisation; 10 min using FM; 10 min using MN. In the second session, FM and MN order was changed and participants did not watch TV. Data were analysed according to the eight combinations among the three studied parameters. Repeated measures ANOVA indicated statistically significant differences for &VO2 (p=0.01) and RMR (p=0.02), with TVMNSEAT showing higher values than TVFMLY. Bland-Altman analysis showed a bias for &VO2, &VCO2, RQ and RMR between TVFMLY and TVMNSEAT of -17.8±14.5 ml.min-1, -8.8±14.5 ml. min-1, 0.03±0.05 and -115.2±101.9 kcal.d-1, respectively. There were no differences in RMR measurements due to body position and apparatus when each variable was isolated. Analyses of distraction in three of four combinations indicated no difference between TV and no TV. In summary, different parameter combinations can result in increased bias and variability and thereby reported differences among children's RMR measurement. The second study dealt with treadmill adaptation and determination of self-selected (SS) walking speed. Assessment of individual and group differences in metabolic energy expenditure using oxygen uptake requires that individuals are comfortable with, and can accommodate to, the equipment being utilised. In this study, a detailed proposal for an adaptation protocol based on the SS was developed. Experiments were carried out on 27 children aged 8-12 (mean age = 10.3±1.2 yr). Results from three treadmill tests following the adaptation protocol showed similar results for step length with no significant differences among tests and lower and no statistically significant variability within- and between-days. Additionally, no statistically significant differences between SS determined over-ground and on a treadmill were verified. These results suggest that SS speed determined over-ground is reproducible on a treadmill and the 10 min familiarisation protocol based on this speed provided sufficient exposure to achieve accommodation to the treadmill. The purpose of the third study was to verify within- and between-day repeatability and variability in children's oxygen uptake ( &VO2), gross economy (GE) [ &VO2 divided by speed] and heart rate (HR) during treadmill walking based on SS. 14 children (mean age = 10.2±1.4 yr) undertook 3 testing sessions over 2 days in which four walking speeds, including SS, were tested. Within- and between-day repeatability was assessed using the Bland and Altman method and coefficients of variability (CV) were determined for each child across exercise bouts and averaged to obtain a mean group CV value for &VO2, GE and HR per speed. Repeated measures ANOVA showed no statistically significant differences in within- or between-day CV for &VO2, GE or HR at any speed. Repeatability within and between-day for &VO2, GE and HR for all speeds was verified. These results suggest that submaximal &V O2 during treadmill walking is stable and reproducible at a range of speeds based on children's SS. In the fourth study, the objective was to establish the effect of walking speed on substrate oxidation during a treadmill protocol based on SS. Experiments were carried out on 12 girls aged 8-12 (mean age = 9.9±1.4 yr). Each participant underwent 2 test sessions, one week apart. Workloads on the treadmill included 2 speeds slower than SS (1.6 [V1] and 0.8 km.h-1 [V2] slower than SS), SS (V3), and a speed 0.8 km.h-1 faster than SS (V4). Indirect calorimetry from respired gas measurements enabled total fat (FO) and carbohydrate (CHO) oxidation rates to be calculated according to the non-protein respiratory quotient (Peronnet and Massicote, 1991) and percentage of CHO and FO calculations using equations from McGilvery and Goldstein (1983). Repeated measures ANOVA followed by a Tukey Post Hoc test (p 50%P &VO2 (P &VO2 = the highest &VO2 observed during an exercise test to exhaustion). Results of the current study compared to observations in the literature showed that HR I 140 bpm consistently estimates lower MVPA time than HR > 50%P &VO2. When these two PA indices were compared with individual and standard MET measured minute-byminute, statistically significant differences were verified among all of them at MPA, but no differences were verified at VPA, except between individual and standard METs. However, whether each one of the PA indices used are under- or overestimating time at MVPA is still debatable due to the lack of a gold standard. Finally, each index used in this study classified different numbers of participants as achieving the PA target of 60 min.d-1. The wide variability between indices when attempting to classify children who are achieving the recommended target is cause for great concern because habitually these indices are utilised as screening tools in paediatric and public health settings and used to guide behavioural interventions

Poder relativo del logro contable y del flujo de caja de las operaciones para prever flujos de caja futuros : un estudio empírico en Brasil

Este artigo avalia a efcácia da previsão de fuxos futuros, para um e dois anos à frente, de quatro medidas de desempenho da empresa, sendo duas de fuxo de caixa e duas de lucro, a partir de medidas ex post do Fluxo de Caixa das Operações (FCO), isolado e em conjunto com a variação das alocações (accruals) de curto prazo (∆Accp ), e do Lucro Líquido contábil (LL). A metodologia de previsão é do tipo externo à amostra. São feitas várias previsões anuais e bianuais transversais para as 92 empresas que compõem a amostra, ao longo dos anos de 1996 a 2004. Os desvios (erros) médios absolutos de previsão, a Mediana dos erros e as correlações médias entre os valores reais e projetados das variáveis são apurados e comparados entre si para fns de verifcação da efcácia de previsão dos fuxos futuros de cada um dos três modelos. Os resultados revelam que: (1) LL é superior ao FCO para prever o Lucro Líquido do ano se-guinte, mas, ao contrário, FCO é superior ao LL para prever o Lucro Líquido dois anos à frente; (2) a combinação das alocações de curto prazo (∆AcB cpB) com o FCO não melhora as previsões que são feitas apenas com o FCO, indicando que o Fluxo de Caixa das Operações é mais efcaz para prever fuxos futuros de caixa e de lucro do que o capital circulante líquido; e (3) o Lucro Operacional (LO), como é defnido na legislação societária brasileira, é de difícil previsão. _________________________________________________________________________________ ABSTRACTThis paper evaluates the accuracy of three accounting performance measures (net income – NI, cash fows from operations – CFO, and working capital – WC) for predicting two cash fows (cash fows from operations – CFO, and free cash fows – FCF) and two income metrics (net income – NI, and operating earnings – OE), one and two years in the future. We use out-of-sample regressions for forecasting the above metrics during the time-period from 1996 to 2004. The prediction accuracy of each forecasted variable is evaluated by computing three measures: the mean absolute errors of the forecasted and actual amounts series; the median of the prediction errors; and the squared correlation (R2 ) between the forecasted and the actual amounts. The fndings show that: (1) NI is superior to CFO for predicting NI one year in the future, but CFO overcomes NI when the prediction of NI is for two years in the future; (2) WC does not beat CFO for predicting neither one of the four performance measures one and two years ahead; and (3) operating earnings (OE), as defned in the Brazilian Corporate Law, are diffcult to predict. _________________________________________________________________________________ RESUMENEste artículo evalúa la efcacia de la previsión de fujos futuros, para uno y dos años más adelante, de cuatro medidas de desempeño de la empresa, siendo dos de fujo de caja y dos de benefcio, desde medidas ex post del Flujo de Caja de las Operaciones (FCO), separado y en conjunto con la variación de las ubicaciones (accruals) de corto plazo (∆AcB-cpB), y del Benefcio Líquido contable (LL).

A framework for efficient execution of data parallel irregular applications on heterogeneous systems

Exploiting the computing power of the diversity of resources available on heterogeneous systems is mandatory but a very challenging task. The diversity of architectures, execution models and programming tools, together with disjoint address spaces and di erent computing capabilities, raise a number of challenges that severely impact on application performance and programming productivity. This problem is further compounded in the presence of data parallel irregular applications. This paper presents a framework that addresses development and execution of data parallel irregular applications in heterogeneous systems. A uni ed task-based programming and execution model is proposed, together with inter and intra-device scheduling, which, coupled with a data management system, aim to achieve performance scalability across multiple devices, while maintaining high programming productivity. Intradevice scheduling on wide SIMD/SIMT architectures resorts to consumer-producer kernels, which, by allowing dynamic generation and rescheduling of new work units, enable balancing irregular workloads and increase resource utilization. Results show that regular and irregular applications scale well with the number of devices, while requiring minimal programming e ort. Consumer-producer kernels are able to sustain signi cant performance gains as long as the workload per basic work unit is enough to compensate overheads associated with intra-device scheduling. This not being the case, consumer kernels can still be used for the irregular application. Comparisons with an alternative framework, StarPU, which targets regular workloads, consistently demonstrate signi cant speedups. This is, to the best of our knowledge, the rst published integrated approach that successfully handles irregular workloads over heterogeneous systems.This work is funded by National Funds through the FCT - Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) and by ERDF - European Regional Development Fund through the COMPETE Programme (operational programme for competitiveness) within projects PEst-OE/EEI/UI0752/2014 and FCOMP-01-0124-FEDER-010067.

Foreign Architecture in Brasilia

Surprisingly, Brasilia has a major assortment of foreign architecture, due to the diplomatic complexes it houses in the so-called South and North Embassy Sectors. From an urban point of view, such sectors were envisioned as a great international fair of buildings by renowned professionals. These buildings display a variety of solutions, in which it is always possible to distinguish typical features of the country of origin. In many of them the intention to reflect the modernity of Brasilia prevails; in others, the main objective was to enhance the country’s traditional architecture; and finally there are those in which both alternatives have been harmonized

Pilocarpus spp.: revisão sobre sua constituição química e atividades biológicas

Pilocarpus species have been exploited as the only source of the imidazole alkaloid pilocarpine (used in glaucoma treatment), since its isolation up to the present. Almost all Pilocarpusspecies are native from Brazil. Because of the medicinal importance of pilocarpine, several of them are in the path of extinction. Other secondary metabolites, such as coumarins, flavonoids and terpenes, were described for Pilocarpusspecies. In this review the secondary metabolites, other than pilocarpine, isolated from Pilocarpusspecies and their biological activities were compiled. Although the variety of structures and the importance of the biological activities described in literature for Pilocarpusspecies this is an unexploited field of research in Natural Products and Pharmacology.Espécies de Pilocarpus têm sido exploradas como única fonte do alcalóide imidazólico pilocarpina (utilizado no tratamento do glaucoma) desde o isolamento dessa substância até os dias atuais. A maioria das espécies de Pilocarpus conhecida é nativa do Brasil e, devido à importância medicinal que a pilocarpina possui e ao desmatamento, várias se encontram em risco de extinção. Outros metabólitos secundários entre os quais cumarinas, flavonóides e terpenos foram descritos em espécies desse gênero. Nesta revisão foram relacionados os metabólitos secundários isolados em diversas espécies de Pilocarpus bem como suas atividades biológicas. Apesar da variedade de estruturas e as importantes atividades biológicas já descritas na literatura para as outras classes de metabólitos secundários, ainda há um vasto campo de estudo para as espécies de Pilocarpus
