The role of mathematics courses in creating and developing students’ research competencies within the social and economic field

Training specialists in social and economic areas should be regarded as a key priority. It is crucial to endow students of relevant specialties with basic mathematical knowledge and skills, to help these people fulfill their professional functions and use the main data sources, along with various mathematical methods, which can be efficiently used within economics and sociolog

Reflecting on knowledge management as an enabler of innovation in project-based construction firms

Purpose: This paper aims to explore the ways innovation becomes enabled through knowledge management and sharing which has important implications for establishing and sustaining the culture of innovative thinking in project-based construction firms. This study adopts a reflective practitioner perspective to explore this relationship. Design/methodology/approach: In total, 30 semi-structured interviews were conducted with the construction sector professionals whose roles are most relevant in the connection between innovation and knowledge management. Thematic analysis and cognitive mapping techniques were used to analyse the interview data. Findings: The research findings indicate that due to the complexity of project-based construction firms, a more holistic approach to knowledge management and organisational learning at the firm level is required. This would enable a culture of continuous and coordinated knowledge flow that facilitates innovation and continuous improvement in project-based firms. Practical implications: This paper has important implications for practising managers in project-based construction firms. By better understanding the ways organisational knowledge can be managed to become an enabler of innovation would allow to build and enhance firms’ innovative capabilities, individual and team competencies. There is a real need for innovation knowledge managers as formal job positions in the construction sector. Originality/value: This study contributes to construction innovation and project management research and practice by providing insights into establishing and sustaining the culture of learning and innovative thinking

Review of analytical instruments for EEG analysis

Since it was first used in 1926, EEG has been one of the most useful instruments of neuroscience. In order to start using EEG data we need not only EEG apparatus, but also some analytical tools and skills to understand what our data mean. This article describes several classical analytical tools and also new one which appeared only several years ago. We hope it will be useful for those researchers who have only started working in the field of cognitive EEG

Super rogue waves in simulations based on weakly nonlinear and fully nonlinear hydrodynamic equations

The rogue wave solutions (rational multi-breathers) of the nonlinear Schrodinger equation (NLS) are tested in numerical simulations of weakly nonlinear and fully nonlinear hydrodynamic equations. Only the lowest order solutions from 1 to 5 are considered. A higher accuracy of wave propagation in space is reached using the modified NLS equation (MNLS) also known as the Dysthe equation. This numerical modelling allowed us to directly compare simulations with recent results of laboratory measurements in \cite{Chabchoub2012c}. In order to achieve even higher physical accuracy, we employed fully nonlinear simulations of potential Euler equations. These simulations provided us with basic characteristics of long time evolution of rational solutions of the NLS equation in the case of near breaking conditions. The analytic NLS solutions are found to describe the actual wave dynamics of steep waves reasonably well.Comment: under revision in Physical Review

From the point of view of the science of administration and law and the science of maritime law this paper is the first complex research of organizational and legal bases of ships' agency service. It is noted that in the legal literature, as a whole, problems of ships' agency service have not been discussed from the standpoint of its organizational and legal bases, therefore the science of law has no developed conceptual provisions connected with organizational and legal status of a ship agent, there are no elaborations as for specificity of the state regulation of ships' agency service, its foundations and limits. The thesis discloses the notion substance of a ship agent, clarifies the essence of ships' agency service, points out specific functions of a ship agent which are of administrative nature. There are revealed historical preconditions of ships' agency service, the history of legal regulation of ships' agency service is given, the process of ships' agency service formation as an independent kind of activity is discussed. The thesis lists the comparative characteristic of legal acts, as well as methods of state regulation of ships' agency service in various countries of the world: Belgium, Great Britain, Germany, Holland, Denmark, Italy, Russia, France, Sweden, Japan. There is given an analysis of effective normative legal acts of Ukraine which establish the procedure for implementation of ships' agency service in Ukraine, as well as legal means of its state regulation are determined. The thesis gives compound consideration of mutual relations between state bodies and ship agents when implementing processes of state registration of subjects of ships' agency service, licensing of ships' agency service, control on the part of authorized state bodies over the activity of ship agents and implementation of other means and methods of administrative and legal regulation with respect to ship agents when they perform their functions in organizing and coordinating all operations connected with supply and services of ships, as well as proposes measures for perfection of means of legal regulation of ships' agency service and their use. Proposals are made as for the necessity to simplify state legitimacy of the subjects of ships' agency service activity, to perfect criteria for referring agency service of the merchant marine to licensed types of activity, to introduce definite qualification requirements to persons exercising ships' agency service, to adopt a professional code of conduct for ship agents proceeding from their special status and specifics of activity, as well as the necessity to observe international standards for ship agents

Evidence for the extracellular delivery of influenza NS1 protein

We constructed a reporter influenza A/Puerto Rico/8/1934 virus expressing truncated 124aa N-terminal NS1 protein fused to a luciferase reporter sequence (NanoLuc) without signal peptide. The reproduction activity of the vector correlated well with the luminescent activity in the lysates of infected cell cultures or mouse respiratory organ suspensions. Surprisingly, we found that luciferase enzymatic activity was present not only in the intracellular compartments but also in cell culture supernatants as well as in the sera or bronchiolar lavages of infected mice. This fact allowed us to formulate a working hypothesis about the extracellular delivery mechanism of the NS1 protein. To test this idea, we conducted co-transfection experiments in Vero cells with different combinations of plasmids encoding influenza genomic segments and chimeric NS1-NanoLuc encoding plasmid. We found that the emergence of the luciferase reporter in the extracellular compartment was promoted by the formation of the ribonucleoprotein complex (RNP) from the co-transfection of plasmids expressing PB1, PB2, PA, and NP proteins. Therefore, influenza NS1 protein may be delivered to the extracellular compartment together with the nascent RNP complexes during the maturation of virus particles.We constructed a reporter influenza A/Puerto Rico/8/1934 virus expressing truncated 124aa N-terminal NS1 protein fused to a luciferase reporter sequence (NanoLuc) without signal peptide.
