Strategic planning in universities: a case of Ukraine

The effective management core principles include the obligatory approval of the orga¬nization’s mission and its strategic plan availability. This also applies to specific organizations such as universities. The purpose of the article is to test the hypothesis that to date, most Ukrainian universities do not care about the presence of such attributes of effective performance (at least, they do not publish them on their sites). The site analysis was carried out in the top 50 out of 289 universities in Ukraine. It turned out that 29 out of these 50 have no mission (do not publish it on the site), and eight universities do not have a strategy. It is established that the most common mistakes in the strategy development are the lack of quantitative indicators, giving a special attention to the coverage of the results achieved; inclusion in the text of the document the thematic sections, which do not concern the prospects of university development, etc

The impact of information sphere in the economic security of the country: case of Russian realities

Abstract Novel information technologies have facilitated not only the development of new industries, but also brought new opportunities and challenges. The range of challenges includes threats related to the information security of not only the commercial, but also the public sector of the national economy, which can adversely affect its stability and competitiveness. In view of this, the problem of ensuring information security (IS) in the economic sphere is of particular relevance. Despite the abundance of studies on IS, the impact of the information sphere on the country’s economic security has not yet been sufficiently studied. The purpose of this article was to identify and systematize threats posed to economic security by the information environment and determine a set of measures to protect the areas at risk. Within the framework of the study, two interrelated models were built. The first systematized the IS threats and challenges, whereas the second demonstrated those IS threats that are directly connected with the state’s economic security. At the same time, the models developed allowed focusing on the protection of objects potentially under threat. The research quintessence was represented by the development of recommendations directed at preventing and minimizing the negative impact of information sphere threats to economic security. Hence, a diversified ecosystem of information and economic security of the state was created. The study findings and recommendations can be used by officials of government bodies and other organizations to develop regulatory documents related to the strategy of ensuring information and economic security at various levels (state, regional, corporate)

Evaluation of the effectiveness of national policies of minimization of consequences COVID-19 pandemics

Abstract: The object of research is the effectiveness of the implementation of measures within the national policy to minimize the effects of the COVID-19 pandemic in individual countries. One of the most problematic places is the formation of a policy to minimize the consequences of the COVID-19 pandemic, which would take into account the specifics of the national economy, its margin of safety and aimed at achieving the goals of stabilizing negative economic trends. The pandemic has led to forced quarantine restrictions, which have had a negative impact on national economies. The inability to set up full-fledged business processes has led to rising unemployment and social tensions. An analysis of the main directions of the policy of minimizing the consequences of the pandemic of individual countries that made up the analytical sample. The main characteristics of the measures taken to minimize the effects of the pandemic, aimed at stabilizing the situation in the most crisis segments of the economy: financial assistance to small and medium-sized businesses, tax benefits, job creation and unemployment benefits, stabilization of the budget and banking system. The study used a comparative analysis of the effectiveness of the pandemic confrontation through the prism of the adopted policy by analysing the dynamics of key macroeconomic indicators. This methodological approach involves the involvement of a large database, which presents the main macroeconomic indicators of individual countries and the study of the main parameters of national policies. This ensures that links are identified and that the results of the planned activities are compared. In comparison with known similar methods, this approach allows adding to the base of comparison global indices depending on the purpose of the study and to transform its subject. In the applied aspect, the evaluation of the policy of confronting the pandemic will minimize the cost of time and resources to select and justify effective measures to minimize the negative consequences of unforeseen events and forecast economic trends

High-pressure crystallography shows noble gas intervention into protein-lipid interaction and suggests a model for anaesthetic action

International audienceIn this work we examine how small hydrophobic molecules such as inert gases interact with membrane proteins (MPs) at a molecular level. High pressure atmospheres of argon and krypton were used to produce noble gas derivatives of crystals of three well studied MPs (two different proton pumps and a sodium light-driven ion pump). The structures obtained using X-ray crystallography showed that the vast majority of argon and krypton binding sites were located on the outer hydrophobic surface of the MPs – a surface usually accommodating hydrophobic chains of annular lipids (which are known structural and functional determinants for MPs). In conformity with these results, supplementary in silico molecular dynamics (MD) analysis predicted even greater numbers of argon and krypton binding positions on MP surface within the bilayer. These results indicate a potential importance of such interactions, particularly as related to the phenomenon of noble gas-induced anaesthesia

Structure-based insights into evolution of rhodopsins

Rhodopsins, most of which are proton pumps generating transmembrane electrochemical proton gradients, span all three domains of life, are abundant in the biosphere, and could play a crucial role in the early evolution of life on earth. Whereas archaeal and bacterial proton pumps are among the best structurally characterized proteins, rhodopsins from unicellular eukaryotes have not been well characterized. To fill this gap in the current understanding of the proton pumps and to gain insight into the evolution of rhodopsins using a structure-based approach, we performed a structural and functional analysis of the light-driven proton pump LR (Mac) from the pathogenic fungus Leptosphaeria maculans. The first high-resolution structure of fungi rhodopsin and its functional properties reveal the striking similarity of its membrane part to archaeal but not to bacterial rhodopsins. We show that an unusually long N-terminal region stabilizes the protein through direct interaction with its extracellular loop (ECL2). We compare to our knowledge all available structures and sequences of outward light-driven proton pumps and show that eukaryotic and archaeal proton pumps, most likely, share a common ancestor

Mirror proteorhodopsins

Abstract Proteorhodopsins (PRs), bacterial light-driven outward proton pumps comprise the first discovered and largest family of rhodopsins, they play a significant role in life on the Earth. A big remaining mystery was that up-to-date there was no described bacterial rhodopsins pumping protons at acidic pH despite the fact that bacteria live in different pH environment. Here we describe conceptually new bacterial rhodopsins which are operating as outward proton pumps at acidic pH. A comprehensive function-structure study of a representative of a new clade of proton pumping rhodopsins which we name “mirror proteorhodopsins”, from Sphingomonas paucimobilis (SpaR) shows cavity/gate architecture of the proton translocation pathway rather resembling channelrhodopsins than the known rhodopsin proton pumps. Another unique property of mirror proteorhodopsins is that proton pumping is inhibited by a millimolar concentration of zinc. We also show that mirror proteorhodopsins are extensively represented in opportunistic multidrug resistant human pathogens, plant growth-promoting and zinc solubilizing bacteria. They may be of optogenetic interest

Study of J/ψ Production in Jets

The production of J/ψ mesons in jets is studied in the forward region of proton-proton collisions using data collected with the LHCb detector at a center-of-mass energy of 13 TeV. The fraction of the jet transverse momentum carried by the J/ψ meson, z(J/ψ)≡pT(J/ψ)/pT(jet), is measured using jets with pT(jet)>20  GeV in the pseudorapidity range 2.5 20$GeV in the pseudorapidity range$2.5 < \eta({\rm jet}) < 4.0$. The observed$z$distribution for$J/\psi$mesons produced in$b$-hadron decays is consistent with expectations. However, the results for prompt$J/\psi$production do not agree with predictions based on fixed-order non-relativistic QCD. This is the first measurement of the$p_{\rm T}$fraction carried by prompt$J/\psi$ mesons in jets at any experiment

Tracking of charged particles with nanosecond lifetimes at LHCb

A method is presented to reconstruct charged particles with lifetimes between 10 ps and 10 ns, which considers a combination of their decay products and the partial tracks created by the initial charged particle. Using the $\Xi^-$ baryon as a benchmark, the method is demonstrated with simulated events and proton-proton collision data at $\sqrt{s}=13$ TeV, corresponding to an integrated luminosity of 2.0 fb${}^{-1}$ collected with the LHCb detector in 2018. Significant improvements in the angular resolution and the signal purity are obtained. The method is implemented as part of the LHCb Run 3 event trigger in a set of requirements to select detached hyperons. This is the first demonstration of the applicability of this approach at the LHC, and the first to show its scaling with instantaneous luminosity
