The post-socialist transformation of general and vocational education system has led to the loss of many positive gains that were already achieved earlier. The polytechnic character of our school and its practice-oriented foundations, based on a reasonable combination of basic education and professional and applied training, were seriously undermined. Modern Russian secondary schools have become something like pre-revolutionary classical high schools, without taking into account the significant fact that in pre-Soviet Russia, along with high schools, there was a wide network of real schools. They focused students on further mastering technical professions and active participation in the production sector of the country. Today we are witnessing a global revolution in the spiritual sphere, aimed at changing the very essence of a man. Note that natural science education is valuable not only for its formal method, but also for providing the basis for a correct understanding of the world. It fosters independence of thought and distrust of other people’s words and authorities. This is the best protection of the human mind from all sorts of superstitions delusions and mysticism.

Abstract State Machine (ASM) theory is a well-known state-based formal method. As in other state-based formal methods, the proposed specification languages for ASMs still lack easy-to-comprehend abstractions to express structural and behavioral aspects of specifications. Our goal is to investigate object-oriented abstractions such as interfaces and traits for ASM-based specification languages. We report on a controlled experiment with 98 participants to study the specification efficiency and effectiveness in which participants needed to comprehend an informal specification as problem (stimulus) in form of a textual description and express a corresponding solution in form of a textual ASM specification using either interface or trait syntax extensions. The study was carried out with a completely randomized design and one alternative (interface or trait) per experimental group. The results indicate that specification effectiveness of the traits experiment group shows a better performance compared to the interfaces experiment group, but specification efficiency shows no statistically significant differences. To the best of our knowledge, this is the first empirical study studying the specification effectiveness and efficiency of object-oriented abstractions in the context of formal methods.

Abstract Currently there is a lack of a formal method to utilize previous fixture information into the design of future product and production lines. The utilization of knowledge gained in the design of prior fixtures and the capability assessment of existing reconfigurable fixtures on the design of new product lines allow manufacturing system design for time and cost reductions. This paper presents the evaluation of a fixture design similarity index developed to assess the relevance of current fixtures design information for multi-model production (reconfigurability) or for future production lines design (reusability). The index developed decomposes N-2-1 fixture information into X, Y, and Z data with applicable constrains and part deflection requirements in the X, Y, and Z directions. This allows the evaluation and comparison of physical and performance attributes of any given fixture. An example demonstrating the methodology implementation to single fixture case analysis and conclusions are provided as part of the presentation.

Partial Correction

Attribution processes appear to be an integral part of human visual perception, as low-level inferences of causality and intentionality appear to be automatic and are supported by specific brain systems. However, higher-order attribution processes use information held in memory or made present at the time of judgment. While attribution processes about social objects are sometimes biased, there is scope for partial correction. This chapter reviews work on the generation, communication, and interpretation of complex explanations, with reference to explanation-based models of text understanding that result in situation models of narratives. It distinguishes between causal connection and causal selection, and suggests that a factor will be discounted if it is not perceived to be connected to the event and backgrounded if it is perceived to be causally connected to that event, but is not selected as relevant to an explanation. The final section focuses on how interpersonal explanation processes constrain causal selection.
