Situational and game technologies of training in students’ professional competence development

The transition from traditional educational paradigm to competence one has marked new ways of higher educational institutions development. The implementation of modern Federal state educational standards requirements has determined the need to use modern specialist methods in training that develop students’ competence and the ability to carry out highly qualified professional activities. Higher education institutions face the task of implementing technologies that contribute to the development of practical orientation of students, their independence in this process. The purpose of the article is to reveal the experience of using situational-game technologies of training, as one of the most practice-oriented, aimed at activating students’ students, contributing to professional competence development. The concept of "technology" came to education from the sphere of production. Technologization implies a clear subordination to a certain algorithm of actions, so the technology allows you to achieve specific results in the allotted amount of time. In the field of professional education, technology has changed, but its meaning remains the same-the regulation of the activities of the subjects of the educational process to achieve the planned goals. The article defines the essence of educational technologies in the training of University students, reveals the features of their application, the role and advantages of situational and game technologies of training in the conditions of implementation of the competence approach. The research given in this article shows the importance of game educational technologies and the prospects of their use in the training a highly qualified, creative specialist who can quickly solve professional problems in non-standard ways

Coherent summation of emission from relativistic Cherenkov sources as a way of production of extremely high-intensity microwave pulses

For relativistic Cherenkov devices, we investigate the process of high-power microwave pulse generation with its phase correlating to the sharp edge of an e-beam current pulse. Our theoretical consideration is referred to quasi-stationary and superradiative (SR) generation regimes when spontaneous emission of the e-beam edge serves as the seed for the development of further coherent oscillations. Phase correlation of the excited microwave pulses with the characteristics of the current pulse front and/or an initial external electromagnetic pulse has been additionally confirmed by particle-in-cell simulations. Pulse-to-pulse stability of the radiation phase within several percents of the oscillation period makes it possible to arrange multichannel schemes producing mutually coherent microwave pulses. In the experiments that have been carried out, the cathodes of independent generators were powered by identical accelerating pulses from strictly synchronized voltage modulators, or by splitting the pulse from a single powerful modulator. For the 2-ns regime with the power of each Ka-band backward-wave oscillator about 100 MW, we demonstrate quadratic growth of the power density in the interference maximum of the directional diagram. In a short pulse SR regime, with the peak power of 600 MW in a single channel, for a four-channel 2-D array, we attained a 16-fold radiation intensity gain

Essays in Labor and Transportation Economics

The study of pricing is a fundamental topic in economics. This dissertation analyzes pricing strategies in labor and transportation markets. Chapter 1 examines the impact of the crash of Alaska Airlines Flight 261 on the domestic fares and passenger traffic of the crash carrier, using a difference-in-difference approach. The results show that that the crash reduced fares of Alaska Airlines relative to those of its competitors only in the months right after the crash, indicating that the financial ramifications are not persistent, a finding that justifies the temporary drop in stock prices found in earlier literature. Chapter 2 investigates the factors that contribute to wage selection in the labor market. When employers consider a job candidate, character assessment about the applicant is gathered from a variety of sources, impartial and subjective, ranging from academic merits to reviews by coworkers. The information is collected in order to make an appropriate wage offer. Existing experimental literature in agency theory provides employers with their employees' work records at no cost. I extend this research by placing a price on the information to develop a more realistic case. Through experimental evidence, I find employers absorb the cost of obtaining history, and do not shift the burden of the fee onto the employees in the form of lower wages. If employers have access to employees' history, they offer wages that are positively correlated with the employees' work ethic. However, when they are not presented with a history, the employers base wages on their own experiences. The last chapter studies a different source an employer can use to determine wages. In past labor market experimental literature, an employee's work history was information the employer received from the employee. Chapter 3 of my dissertation modifies the agency problem by introducing a noisy signal from a third party, specifically the employee's past employer. The results of this experimental study show that cooperation is more prominent when employee references are accessible, even if the evaluations are imprecise

Controlling of Strategic Organizational Changes at the University

Since modern organizations are characterized by a variety of goals, the definition of the effectiveness of organizational changes can be specified as a degree of results achievement (under the conditions that these results are adequate to the established and intended goals of organizational changes and the changes themselves meet certain needs of stakeholders and create conditions for constant development of an organization). This research is based on general scientific research methods: system analysis methods, scientific abstraction and generalization, comparative and categorical analysis, empirical description methods, as well as behavioral, systematic, process specifying scientific methodological approaches of the theory of management. The authors classified strategic interests of the main stakeholders in universities activities in Russian Federation; the element base and the system of interactions between them was performed in the model of interests coordination during the changes implementation process in the system of higher education and control methods when making changes were analyzed. In conclusion various forms of controlling were suggested and this variation was derived from various university stakeholders’ interests

Sorption Recovery of Platinum Metals from Production Solutions of Sulfate-Chloride Leaching of Chromite Wastes

This paper discusses the scientific rationale for methods of platinum metals sorption centralization from saturated solutions with a high content of macrocomponents. Methods of sorption centralization of platinum and iridium using local anionites such as AH-31, AB-17-8, Purolite S985 are described. The sorbents used were conditioned to remove organic and mineral impurities. The sorption isotherms of platinum group metals 1/EC=f(1/Cp) at a temperature of 20 °C and a duration of 24 h were plotted. The data on the sorption recovery of platinum and iridium from individual and combined sulfate-chloride solutions were determined. Isotherms of iridium sorption from sulfate-chloride solution are formed. Results of the apparent sorption equilibrium constant and values of standard Gibbs energy (ΔG, kJ/mol) of ion exchange for sorption of platinum and iridium from individual and combined sulfate-chloride solutions are presented. Linearized isotherms and kinetic curves of joint sorption of platinum and iridium from sulfate-chloride solution are described. Comparative sorption of the platinum-group metals (PGM) by anionites AB-17-8 and Purolite S985 from sulfate-chloride solutions is shown. The sorption diagram of platinum and iridium from sulfate-chloride product solutions is presented. It has been revealed that complete recovery is achieved using chelation ion-exchange resin Purolite S985, with recovery of Pt up to 95% and Ir more than 73%. The sorption process is accompanied by intradiffusion constraints that are confirmed by the analysis of kinetic curves using Schmukler and Boyd–Adams models
