THE NEWSPAPER “RECH" IN 1941-1944 AS A SOURCE OF THE RUSSIAN ORTHODOX CHURCH HISTORYDURING THE GREAT PATRIOTIC WAR
No full textThe article analyzes the materials on religious themes, published in the collaborationist newspaper “Rech” on the occupied territory in 1941-1944. The main focus is on the classification of publications (there were selected factual, idiomatic, comparative, anti-Semitic and historical articles) and their propaganda component. The author considers the qualitative and quantitative evolution of the newspaper materials on religious life. The conclusion is drawn on their scientific potential and connection with military operations and changes in the policy of the Soviet state. The analysis of the central line of comparison of religious life during the pre-revolutionary period, the Soviet period and during the occupation in all publications enables to reveal the methods of invaders’ propaganda activities. The consideration of other thematic lines and their literary features helps to present the ideological potential of the newspaper in the creation of the collaborationist movement, and to characterize “Rech” as the information source for the population of the occupied territories
Divergent isokinetic muscle strength deficits in street running athletes
No full textBackground: Running is a very popular activity and muscle strength imbalance has been treated with caution to prevent injuries. Aim: The present study aimed to compare and correlate knee flexion and extension strength imbalance based on peak torque (PT) and total work (TW) in running athletes. Methods: Thirty-eight male amateur running athletes (38 ± 6 years; 80.6 ± 8.3 kg; 177 ± 7 cm; 7.8 ± 8.4 years of training; 3.5 ± 0.9 training sessions a week; 33.5 ± 13.4 km of training per week) took part in the present study. Knee flexion eccentric and concentric PT and TW, as well as concentric knee extension PT and TW were assessed. PT- and TW-based hamstring-to-quadriceps ratios (H:Q), as well as PT and TW contralateral imbalance were quantified. Results: A significant correlation was observed between TW and PT concentric knee flexion contralateral deficits (r = 0.52, p 0.05). All mean comparisons of H:Q and contralateral imbalances using TW or PT were significantly different (p < 0.05). Conclusions: Our results showed that TW and PT muscle strength imbalance were unrelated, and the H:Q and contralateral imbalance profile of endurance runners may differ based on the isokinetic variable analyzed

Recent Trends and Perspectives on Defect-Oriented Testing
No full textElectronics employed in modern safety-critical systems require severe qualification during the manufacturing process and in the field, to prevent fault effects from manifesting themselves as critical failures during mission operations. Traditional fault models are not sufficient anymore to guarantee the required quality levels for chips utilized in mission-critical applications. The research community and industry have been investigating new test approaches such as device-aware test, cell-aware test, path-delay test, and even test methodologies based on the analysis of manufacturing data to move the scope from OPPM to OPPB. This special session presents four contributions, from academic researchers and industry professionals, to enable better chip quality. We present results on various activities towards this objective, including device-aware test, software-based self-test, and memory test.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Quantum & Computer EngineeringComputer Engineerin
Application of a new optimal operating strategy to a smart energy system in the de-regulated electricity market
No full textOver the last years, the electricity sector has drastically changed due to an increasing penetration of renewable energy sources (RES). RES have a stochastic nature that can be predicted with a limited accuracy. This brings new challenges for the optimal operation of energy systems fueled by RES. Some studies in the literature show that the intermittent nature of RES can be smoothed by a proper coupling between renewable and conventional production units, responsive demand, or energy storages.
In this study, an original optimal market offering strategy suggested by the first author is applied to an energy system fueled by both dispatchable and non-dispatchable renewable sources. The goal is to operate the system according to smart rules which allow the system to maximize profits (i.e. to operate it as a “smart energy system”). The system includes a photovoltaic system, two CHP internal combustion engines (bio-oil and bio-gas fueled), six woodchip boilers and both an electric and a thermal storage system. These units generate electricity and heat for a group of users having variable demands and trade electricity with the grid through a two-settlement electricity market (i.e. day-ahead and balancing). Market participation is of crucial importance, since the offers in the day-ahead market need to be submitted from 12 to 36 hours prior to real-time operation and influence the future optimal operation. Thus, all variables related to the operation of the “smart system” have been modeled as “recourse” decisions in the developed tool for optimal offers at the day-ahead stage.
The offering strategy is tested against a deterministic alternative in a case study. Results show how a full information on the stochastic processes can help exploit synergies between the heat and electric systems, yielding to lower expected operating costs
O ato livre e a criação artística: relações entre a filosofia de Bergson e a literatura de Proust
No full textRECH, Luiz Ricardo. O ato livre e a criação artística: relações entre a filosofia de Bergson e a literatura de Proust. Argumentos Revista de Filosofia, Fortaleza, v. 2, n. 4, p. 61-68, 2010.Exists a strong relationship between Bergson’s philosophy and art. The tendency of his thought to the
study of psychological questions establish a continuous dialogue with art, be by the use of metaphor
and poetical images, be by the references that can be found in his texts, especially in respect to
the study of subjectivity. In other way, analyzing the Proust’s work can be perceived there, in many
moments, a clear example of what Bergson called pure duration. Two approaches can be done:
the duration according to the narrator character of No Caminho de Swann is constructed; and the
memories of the own author, essentials to the creation of the environment where the psychological
profiles can be developed by his artistic expression. In this intersection, seems to us feasible to suggest,
in this way, a comparison between the free action ruled on the duration and the artistic production
like an expression of the duration of that creates, considering in foundation the bergsonian
interpretation of this questions.Há uma forte relação entre a filosofia de Bergson e a arte. A tendência do seu pensamento ao estudo
das questões psicológicas estabelece um diálogo constante com a arte, seja pelo uso da metáfora e
das imagens poéticas, seja pelas referências que se encontram em seus textos, principalmente no
que diz respeito ao estudo da subjetividade. Por outro lado, analisando-se a obra de Proust pode-se
perceber ali, em muitos momentos, um claro exemplo do que Bergson chamou de duração pura.
Duas podem ser as aproximações: a duração segundo a qual se constrói o personagem narrador de
No Caminho de Swann; e as memórias do próprio autor, fundamentais para a criação do ambiente
onde os perfis psicológicos se desenvolvem mediante a sua expressão artística. Nesse intercurso,
parece-nos viável propor, dessa forma, um paralelo entre o ato livre pautado na duração e a produção
artística como expressão da duração daquele que cria, tomando por base a interpretação
bergsoniana dessas questões

Previous issue date: 2013-03-27Companies are always looking for competitive advantage, costs reduction, quality increasing and more productivity. Software development is part of this context, with contributions from the areas of Software Engineering and Project Management, aiming at producing software with quality, with less waste, and with the speed required in today's market. To meet this challenge, the software development industry has sought new ways to develop new products. The adaptive approaches, with practices that seek to be more flexible than prescriptive approaches, often considered cumbersome and slow, emphasize the agility of software development processes, seeking greater efficiency in situations where changes are common. The Scrum framework is one of the most popular agile methods and it is considered an adaptive approach for project management. It defines a set of practices implemented through iterative and incremental cycles, with constant involvement and visibility of the customer, providing quick delivery and business value. However, risk management, which is a very relevant practice in conducting projects, is implicitly treated in projects that use adaptive approaches such as Scrum. Thus, the aim of this work is to develop an empirical study that seeks to identify how the list of common risks found in the software project management literature is managed in Scrum. In order to develop this research we have used secondary (systematic literature review) and primary studies (field study). This research contributes to the theory and practice of software project management, specifically in the area of risk management and its intersection with the Scrum framework.As empresas est?o sempre em busca de vantagens competitivas, redu??o de custos, aumento de qualidade e produtividade.

Entendendo o impacto de integração de núcleos e sistema operacional sobre a confiabilidade em sistemas baseados em ARM
No full textReliability has become one of the main issues for computing devices employed in several domains. This concern only deepens with the increase of integration in the same chip of several peripherals and accelerators. To evaluate computational system reliability, fault injection and radiation experiments are used. Fault injection in microarchitectural models of the processor provides deep insights on faults propagation through the entire system stack, including the operating system. Beam experiments, on the other hand, estimate the device’s expected soft error rate in realistic physical conditions by exposing it to the accelerated particle beam. Combining beam experiments and fault injection data can deliver deep insights about the device’s expected reliability when deployed in the field. However, it is yet largely unclear if the fault injection error rates can be compared to those reported by beam experiments and how this comparison can lead to informed soft error protection decisions in early stages of the system design. In this work, first, the data gathered with extensive beam experiments (on physical CPU hardware) and microarchitectural fault injections (on an equivalent CPU model on Gem5) performed with 13 different benchmarks executed on top of Linux on an ARM Cortex-A9 microprocessor are presented and analyzed. We then compare the soft error rate estimations that are based on neutron accelerated beam and fault injection experiments. We show that, for most benchmarks, fault injection can be very accurately used to predict the Silent Data Corruptions (SDCs) rate and the Application Crash rate. The System Crash rate measured with beam experiments, however, is much larger than the one estimated by fault injection due to unknown proprietary parts of the physical hardware platform that can’t be modeled in the simulator. Overall, our analysis shows that the relative difference between the total error rates of the beam experiments and the fault injection experiments is limited within a narrow range of values and is always smaller than one order of magnitude. This narrow range of the expected failure rate of the CPU provides invaluable assistance to the designers in making effective soft error protection decisions in early design stages. After that, the impact of cores integration and the OS interference on the reliability of Arm microprocessors is also analyzed and quantified. But in this analysis besides the same Arm Cortex-A9, as used in the previous analysis, a standalone Arm Cortex-A5 is also tested with both neutron beam and microarchitecture-level fault injections (on equivalent CPU models of the A5 and A9 CPUs on Gem5 simulator). Correlating the beam experiments to the fault injection results it was found that due to the peripherals and interfaces, the integration of various cores significantly increases the System Crash rates but has a negligible impact on the SDC rate which is attributed to the CPU cores. Moreover, the OS has a beneficial impact on the Application Crashes but not on the System Crashes nor the SDC rates. The results of this second analysis firmly confirm, on two different CPU cores, the initial findings and speculations from the first analysis that the SDC part of the overall system failure rate is minimally affected by the SoC integration and the existence of the OS, while the Crashes parts are more severely affected by both aspects. The findings can be employed to support diligent design decisions for CPU cores error protection at the hardware or software level.A confiabilidade se tornou um dos principais problemas em dispositivos de computação empregados em vários domínios. Essa preocupação apenas se aprofunda com o aumento da integração no mesmo chip de vários periféricos e aceleradores. Para avaliar a confiabilidade de um sistema computacional, são utilizados experimentos de injeção de falhas e de radiação. A injeção de falhas em modelos microarquiteturais do processador, por um lado, fornece informações detalhadas sobre a propagação de falhas em todo fluxo do sistema, incluindo o sistema operacional. Os experimentos com radiação, por outro lado, estimam a taxa de erro mais proximo de condições físicas realistas, expondo-o a fluxos acelerados de partículas. A combinação de experimentos de radiação e dados de injeção de falhas pode fornecer informações profundas sobre a confiabilidade esperada do dispositivo quando implantado em campo. No entanto, ainda não está claro se as taxas de erro de injeção de falha podem ser comparadas com as relatadas por experimentos com radiação e como essa comparação pode levar a decisões concientes sobre proteção de erros nos estágios iniciais do projeto de um sistema. Neste trabalho, primeiro são apresentados e analisados, os dados coletados com extensos experimentos de radiação (no hardware físico da CPU) e injeções de falhas microarquiteturais (em um modelo de CPU equivalente no Gem5) realizadas com 13 benchmarks diferentes executados no Linux em um microprocessador ARM Cortex-A9. Em seguida, comparamos as estimativas de taxa de erro leve baseadas em experimentos de radiação de nêutrons e injeção de falhas. Mostramos que, para a maioria dos benchmarks, a injeção de falhas pode ser usada com muita precisão para prever a taxa de SDCs (Silent Data Corruptions) e a taxa de falha do aplicativo. A taxa de falha do sistema medida com experimentos de radiação, no entanto, é muito maior que a estimada por injeção de falha devido a partes proprietárias desconhecidas da plataforma de hardware físico que não podem ser modeladas no simulador. No geral, nossa análise mostra que a diferença relativa entre as taxas de erro total dos experimentos de radiação e as experiências de injeção de falha é limitada dentro de uma faixa estreita de valores e é sempre menor que uma ordem de magnitude. Esse intervalo estreito da taxa de falhas esperada da CPU fornece assistência inestimável aos projetistas na tomada de decisões eficazes de proteção contra erros desoftware nos estágios iniciais do projeto. Depois disso, o impacto da integração dos núcleos e a interferência do Sistema Operacional na confiabilidade dos microprocessadores Arm também são analisados e quantificados. Mas nessa segunda análise, além do mesmo Arm Cortex-A9 usado na análise anterior, um Arm Cortex-A5 também é testado com injeções de falha no nível de microarquitetura (em modelos de CPU equivalentes dos processadores A5 e A9 no Gem5 simulador) e na radiação de nêutrons. Correlacionando os experimentos de radiação com os resultados da injeção de falhas, verificou-se que, devido aos periféricos e outras interfaces, a integração aumenta significativamente as taxas de falha do sistema, mas tem um impacto insignificante na taxa de SDC atribuída aos núcleos da CPU. Além disso, o sistema operacional tem um impacto benéfico nos travamentos de aplicativos, mas não nos travamentos do sistema nem nas taxas de SDC. Os resultados desta segunda análise confirmam firmemente, em dois núcleos diferentes de CPU, as descobertas e especulações iniciais da primeira análise de que a parte SDC da taxa geral de falhas do sistema é minimamente afetada pela integração do SoC e pela existência do sistema operacional, enquanto os Crashes são mais severamente afetadas por ambos os aspectos. Ambas descobertas podem ser empregadas para apoiar decisões de projeto com o objetivo minimizar a taxa de erros tanto no nível de hardware quanto no de software
Consumer reactions to pay-what-you-want and name-your-own-price mechanisms

Journal of Consumer Behaviour, 21(4), 641-652. https://doi.org/10.1002/cb.2019 ------Funding information: Fundação para a Ciência e a Tecnologia, Grant/Award Number: DSAIPA/DS/0113/2019 ---%ABS2%Pay-what-you-want (PWYW) and name-your-own-price (NYOP) participative pricing mechanisms are becoming more popular among firms. In response, researchers have examined separate outcomes for each mechanism. However, questions remain, especially regarding which mechanism is most beneficial for consumers and companies. Therefore, our main objective is to investigate the role of these participative pricing mechanisms on consumers' pricing satisfaction, pain of payment, and amount of money they intend to pay. We also explore perceived control as mediating the effect of pricing mechanism on pricing satisfaction and pain of payment. Results from two experimental studies indicate that consumers are more satisfied with the pricing mechanism and feel less pain of payment under PWYW offers rather than under NYOP offers, but they intend to pay less than they would have paid for NYOP. External reference prices (ERPs) act as a boundary condition. That is, in both PWYW and NYOP pricing conditions, when retailers use ERPs, consumers intend to pay more but they are less satisfied with pricing and feel more pain of payment. The article concludes with implications for retailers using participative pricing.authorsversionpublishe
