Peer reviewing has been touted as a popular instrument to identify good contributions in communities. A problem of peer reviewing is that reviewers have little incentive to make significant effort. To address this problem, the authors introduce a new variant of peer reviewing. It differs from conventional peer reviewing in two ways: First, peers who have made a contribution must also review the contributions made by others. Second, each contributor issues ratings regarding the reviews he has received. To incentivize reviewing, they design an assessment scheme which does not only assess the quality of the contribution made by a peer, but also the quality of the reviews he has submitted. The scheme ranks peers by overall performance, and the ranks determine their payoff. Such a setting gives way to competition among peers. A core challenge however is to elicit objective reviews and ratings. The authors consider two issues which are in the way of this objectiveness: First, they expect preference bias in ratings, i.e., peers tend to prefer reviews with high scores, but dislike reviews with low scores. Second, strategic peers might defame others in their reviews or ratings. This is because they perceive others as competitors. In this paper, they propose a heuristic to address these issues. Further, they carry out a user study in a lecture scenario to evaluate their scheme. It shows that students are incentivized to submit high-quality reviews and that their scheme is effective to evaluate the performance of students.

Overall Performance

The performance of adversarial dialogue generation models relies on the quality of the reward signal produced by the discriminator. The reward signal from a poor discriminator can be very sparse and unstable, which may lead the generator to fall into a local optimum or to produce nonsense replies. To alleviate the first problem, we first extend a recently proposed adversarial dialogue generation method to an adversarial imitation learning solution. Then, in the framework of adversarial inverse reinforcement learning, we propose a new reward model for dialogue generation that can provide a more accurate and precise reward signal for generator training. We evaluate the performance of the resulting model with automatic metrics and human evaluations in two annotation settings. Our experimental results demonstrate that our model can generate more high-quality responses and achieve higher overall performance than the state-of-the-art.

Isn’t the existent always the outcome of any creative confrontation? Is such a creative discussion really out of a contextual consideration? Isn’t every context – even a purely spiritual one – part of the heritage? In his contribution, Walter Angonese reflects on the potential of the pre-existent on the architectural project. He believes in “thinking ahead” and consequently in “building on”, and that is why the question of the relevance of existing structures to architectural design has been clarified. However, he also believes that the quality of the existent can only be improved thanks to an increased habit of awareness and not only following and blaming the prescribed laws for quality assurance. This awareness raising gives responsibility to the individual within a society, but also makes him responsible for his own actions. Building in an alpine context – like any building, by the way – is therefore a question of responsibility, towards oneself and towards one’s society. If the architectural idea is built by leading it from an intuition about a cultural reflection to what one can call a real “architectural idea” (and not merely any intuition), then that is an important first step for a high-quality “continuing construction” of the existing. Only the heritage and the existent can become a meaningful starting point of the project.

Basically, zakat in Islamic teaching is the one of effective and strategic ways to be developed in increasing prosperous of people. So, it can be very potential. The potency of zakat will be great and useful if the institution of zakat administrator can manage effectively and overcome all classic problems always faced by administrators. Managerial skill, accountability, integrity, and truth are the main capitals to manage zakat. Meanwhile, empowering, supervising, and teaching on the people who received zakat (mustahiq) are some important things that should be thought. Therefore, the institution of zakat management should get the way to change people perspective from receiver to giver (mustahiq to muzakki). The strategies are to accustom for paying zakat, to be creative and smart in collecting zakat, distribute zakat effectively, create high quality of human resources, and to be focus on the programs of developing zakat.DOI: 10.15408/ajis.v16i1.2899

Continuously Cast

Free-cutting steel gains specific working properties thanks to the high content of sulfur and phosphorus. These elements, especially sulfur, have a rather high tendency to segregation. Therefore, segregation defects in free-cutting steel continuously cast billets can be significantly developed. The aim of the work was to study the influence of the chemical composition of freecutting steel and casting technological parameters on the quality of the macrostructure of continuously cast billets. A metallographic assessment of the internal structure of cast metal made of free-cutting steel and data processing by application of correlation and regression analysis were the research methods. The array of production data of 43 heats of free-cutting steel of grade A12 was studied. Steel casting on a five-strand radial type continuous casting machine was carried out by various methods of metal pouring from tundish into the molds. Metal of 19 heats was poured with an open stream, and 24 heats – by a closed stream through submerged nozzles with a vertical hole. High-quality billets had a cross-sectional size of 150×150 mm. The macrostructure of high-quality square billets made of free-cutting steel of A12 grade is characterized by the presence of central porosity, axial segregation and peripheral point contamination, the degree of development of which was in the range from 1.5 to 2.0 points, segregation cracks and strips – about 1.0 points. In the course of casting with an open stream, almost all of these defects are more developed comparing with the casting by a closed stream. As a result of correlation and regression analysis, linear dependences of the development degree of segregation cracks and strips both axial and angular on the sulfur content in steel and on the ratio of manganese content to sulfur content were established. The degree of these defects development increases with growing of sulfur content in steel of A12 grade. These defects had especially strong development when sulfur content in steel was of more than 0.10%. To improve the quality of cast metal, it is necessary to have the ratio of the manganese content to the sulfur content in the metal more than eight.

The experience of clinical testing of the personal telemedicine system ‘Obereg’ for remote monitoring of patients at the intensive care units of leading Russian clinics is described. The high quality of communication with the remote receiving devices of doctors, the accuracy of measurements, resistance to interference from various hospital equipment and the absence of its own impact on such equipment were confirmed. There are significant advantages compared to stationary patient monitors, in particular, for intra and out-of-hospital transportation of patients.

Methodological Aspects

The transthoracic echocardiography made by multifrequency probes with support of the mode of the second harmonic imaging, is a competitive method for visualization of the main coronary arteries and allows to estimate coronary blood flow with high quality. Of course, the method has considerable restrictions, most important of which is the low spatial resolution of a method, due to small acoustic window. Because of this the transthoracic visualization of coronary arteries perhaps will not become the leading method of anatomic reconstruction of separately taken coronary artery and especially all coronary arteries system. However uniqueness and indisputable advantage of this method is an opportunity to noninvasively estimate a coronary blood flow both once, and in dynamics.
