Caring for the sick man? Russian and Greek reactions to the Ottoman reforms (1856–1908)

Abstract: Before the Crimean War (1853–1856), Greece and Russia had had a long and complicated relationship to the Ottoman Empire and especially to its sizable Orthodox Christian minority. The Sick Man of Eu...

The effect of prism on preferred retinal locus

Abstract: BACKGROUND Whether prism, especially base-up prism, affects the area of the retina used for fixation in a patient with central scotoma has been a controversial subject for 35 years. Our pilot study employed microperimetry to evaluate the effect of base-up prism on the fixation locus, or preferred retinal locus (PRL), in subjects with central scotoma. METHODS We used a microperimeter to assess the PRL in 13 visually impaired subjects with central scotoma under four conditions: no lens, a lens with no prism (control lens), 6Δ base-up, and 10Δ base-up. The PRL was measured in degrees in horizontal and vertical co-ordinates from the centre of the optic disc using graphical analysis. RESULTS The PRL with the control lens was not significantly different from the PRL with no lens. The preferred retinal loci with the two powers of prism were compared to the control lens and showed a superior shift in 22 of 26 cases (84.6 per cent). The amount of movement was significantly different from zero (p = 0.001 for 6Δ and p = 0.004 for 10Δ ). The vertical movement with the 10Δ prism (1.73 ± 1.73 degrees) was not significantly greater (p = 0.562) than with the 6Δ prism (1.37 ± 1.08 degrees). The shift was significantly less than the prism powers used (p < 0.001), and the amount of vertical relocation was not significantly different from the amount of horizontal movement. CONCLUSION In our study, base-up prism appears to shift the PRL in the direction of the prism base most of the time, but our findings do not support the use of prism as a way of predictably relocating the PRL. More study is indicated to evaluate whether such a small shift is clinically or functionally significant.

Variability of mitochondrial DNA cytochrome b gene in the red vole Clethrionomys rutilus Pallas, 1779, population in the flood-plain middle stream of the Kolyma River

Abstract: The intrapopulation variability of a cytochrome b gene fragment and the corresponding amino acid sequence was studied in the red vole Clethrionomys rutilus Pallas, 1779 from the flood-plain of the Kolyma River. Wide polymorphic variability of these properties was observed. Differences in the cytochrome b gene sequence were determined between the red voles of the studied population and the species collected in neighborhoods of Novosibirsk and Omsk. The revealed results point to the urgency of the cytochrome b gene nucleotide sequence and the variants of the respective amino acid sequence as genetic markers of originality of different red vole populations.

Directions and Resource Support of Information and Communication Policy of Hi-Tech Enterprises in the Conditions of Digitalization of the Economy

Abstract: The increased role of communicative interactions in the functioning and development of modern organizations is due to serious technological changes that introduce new characteristics both to the global economic system and to the economy of individual markets and enterprises. In this regard, the purpose of this study was to address topical issues in the implementation of the information and communication policy of hi-tech enterprises in the digitalization environment. The article specifies the concepts related to the content of information and communication policy, the direction of its formation and management. Attention is paid to methodological problems related to the investigation of opportunities and threats in the field of the information and communication environment of the enterprise that have emerged with the development of the digital economy and affect the success of business in an updated postindustrial society. Express diagnostics of the current state of the adaptation level of the information and communication policy of Russian enterprises in the conditions of digitalization of the economy was carried out. The theoretical and practical basis were the research papers of Russian and foreign scientists related to the management of information and communication business space, and internal reporting of Russian enterprises. Methodical basis of the study were selected system analysis, logical analysis methods, and statistical methods. The developments outlined in this article represent the author’s contribution for improving the efficiency of adaptation of Russian enterprises to the conditions and requirements that are emerging in the development of the digital economy.
