Самораскрытие в педагогическом процессе: время и своевременность
The article is devoted to the problem of selfdisclosure of a personality as implicit readiness to active self-fulfillment. The author examines positive and negative consequences of self-disclosure in communication and studies temporal boundaries, time and relevance of self-disclosure of a person in dyadic, interpersonal and inter-group relationship.
The results of cross-cultural research of implicit theories of innovativeness among students and teachers, representatives of three ethnocultural groups: Russians, the people of the North Caucasus (Chechens and Ingushs) and Tuvinians (N=804) are presented. Intergroup differences in implicit theories of innovativeness are revealed: the ‘individual’ theories of innovativeness prevail among Russians and among the students, the ‘social’ theories of innovativeness are more expressed among respondents from the North Caucasus, Tuva and among the teachers. Using the structural equations modeling the universal model of values impact on implicit theories of innovativeness and attitudes towards innovations is constructed. Values of the Openness to changes and individual theories of innovativeness promote the positive relation to innovations. Results of research have shown that implicit theories of innovativeness differ in different cultures, and values make different impact on the attitudes towards innovations and innovative experience in different cultures.
The considered model of the failure rate of CMOS VHSIC design proposed in the article Piskun G.A., Alekseev V.F., "Improvement of mathematical models calculating of CMOS VLSIC taking into account features of impact of electrostatic discharge", published in the first issue of the journal "Technologies of electromagnetic compatibility" for the year 2016. It is shown that the authors claim that this model "...will more accurately assess the reliability of CMOS VHSIC design" is fundamentally flawed and its application will inevitably lead to inadequate results. Alternatively, the proposed model of the failure rate of CMOS VHSIC design, which also allows to take into account the views of ESD, but based on the use of resistance characteristics of CMOS VHSIC to the effects of ESD.
The article considers the questions assessing the reliability of mechanical components used in the electronic equipment in the early stages of design. The calculations of failure rates springs shock absorbers according to various methods. It is shown that the use of models failure rates of mechanical elements, taking into account the peculiarities of their structural and technological performance, not only allows us to solve the problem of calculating, but also to ensure the required level of reliability and mechanical components, and containing electronic equipment.
The monograph presents results by professor Dr. A. Shalumov’s Research School of Modeling, Information Technology and Automated Systems (Russia). The program, ASONIKA, developed by the school is reviewed here regarding reliability and quality of devices for simulation of electronics and chips during harmonic and random vibration, single and multiple impacts, linear acceleration and acoustic noise, and steady-state and transient thermal effects. Calculations are done for thermal stress during changes in temperature and power in time. Calculations are done for number of cycles to fatigue failure under mechanical loads as well as under cyclic thermal effects. Simulation results for reliability analysis are taken into account. Models, software interface, and simulation examples are presented.
For engineers and scientists involved in design automation of electronics.
Mathematical models of failure rate of refusals the elements applied in calculations of reliability of the onboard electronic equipment are considered. Possibility of application the models given in foreign standards, for forecasting of reliability of completing elements is shown.
The basic influencing the factor defining its reliability are temperature influences at which speed of chemical reaction of materials a part REE increases. It is represented the equation which has been received by the Swedish chemist Svante Arreniusom from thermodynamic reasons
Maintenance of reliability of radio-electronic equipment taking into account thermal modes for various classes of electroradioproducts (ERP) within the limits of system ASONIKA is considered.
Combinatorial abilities are fundamental to experimental thinking. The aim of this work was to design didactic objects that will stimulate preschoolers’ experimental thinking and to study young children’s thinking in relation to these objects. Six heuristic rules for the design of didactic objects are specified, and the responses of 623 children aged between 3 and 7 to the didactic objects are described in this paper. The first two calculating devices required rods to be pressed simultaneously for successive windows to be lit up or made visible. A total of 30 five year olds played with these for 20 minutes, and were seen to perform a logical series of actions in order to understand the device’s function. Half of the children counted the presses and thereby understood the way the device functioned. The second device was designed to allow all possible combinations of four variables. Sixty children between the ages of 4 and 6 played with the device for 20 minutes. A total of 88% of the children found all possible combinations of the device, with no differences between age groups in the strategies used. The third device had a matrix of shutters opened by buttons arrayed along two edges. In the first mode, single buttons presses opened the nearest windows and button presses along both edges opened windows on coordinates determined by the two buttons. In the second mode, single button presses opened nothing and simultaneous button presses along two edges opened windows on coordinates determined by the two buttons. Ninety children between the ages of 5 and 10 played with the device in the second mode for 20 minutes. The children used scientific strategies to discover the device’s function in the following proportions: 20% at five years, 50% at six years and 93% at 10 years. Eighteen children between the ages of 4 and 6 played with the device in the second mode. They played in pairs, and each child was assigned a row of buttons, thus requiring co-operation to open the windows requiring two coordinated button presses. All the children were eventually successful in the joint experimentation. The fourth device had 16 windows and eight buttons, which lit up the windows when pressed in logical combinations. A total of 20 five-year-old children were trained on this device to use combinations of button presses to light up selected windows. These children were then allowed to explore the third device in second mode by themselves. The trained five year olds all used scientific strategies in their search for the third device’s combinations. The study showed that preschoolers can combine actions and discover hidden relationships, and that the didactic objects can be used to develop children’s thinking.
Students' internet usage attracts the attention of many researchers in different countries. Differences in internet penetration in diverse countries lead us to ask about the interaction of medium and culture in this process. In this paper we present an analysis based on a sample of 825 students from 18 Russian universities and discuss findings on particularities of students' ICT usage. On the background of the findings of the study, based on data collected in 2008-2009 year during a project "A сross-cultural study of the new learning culture formation in Germany and Russia", we discuss the problem of plagiarism in Russia, the availability of ICT features in Russian universities and an evaluation of the attractiveness of different categories of ICT usage and gender specifics in the use of ICT.
