The impact of sleep quality on cognitive functioning in Parkinson's disease

In healthy individuals and those with insomnia, poor sleep quality is associated with decrements in performance on tests of cognition, especially executive function. Sleep disturbances and cognitive deficits are both prevalent in Parkinson's disease (PD). Sleep problems occur in over 75% of patients, with sleep fragmentation and decreased sleep efficiency being the most common sleep complaints, but their relation to cognition is unknown. We examined the association between sleep quality and cognition in PD. In 35 non-demented individuals with PD and 18 normal control adults (NC), sleep was measured using 24-hr wrist actigraphy over 7 days. Cognitive domains tested included attention and executive function, memory and psychomotor function. In both groups, poor sleep was associated with worse performance on tests of attention/executive function but not memory or psychomotor function. In the PD group, attention/executive function was predicted by sleep efficiency, whereas memory and psychomotor function were not predicted by sleep quality. Psychomotor and memory function were predicted by motor symptom severity. This study is the first to demonstrate that sleep quality in PD is significantly correlated with cognition and that it differentially impacts attention and executive function, thereby furthering our understanding of the link between sleep and cognition.Published versio

Jargon in sport discourse: formation and functioning

The paper discusses the major ways of sport jargon formation and the peculiarities of its functioning. Jargonisms come into the Russian word-stock through both borrowings from other languages (mostly English) and discourses. Among the productive means of word-stock enrichment are metaphorization, author’s word-building, blending and other

COMPUTER VISUALIZATION IN ECOLOGICAL EDUCATION

The idea to use computer visualization in ecological education is promoted. A fragment of the virtual ecological trip “Lake Pryazhinskoe” is demonstrated. The approach to create virtual trips is based on Web-design technologies. The virtual ecological trips will open new innovative and creative possibilities for ecological education both at the stage of their development and their application

Structural and Functional Organization of Photosynthetic Apparatus in Wild Halophites

The structural and molecular parameters of photosynthetic apparatus in plants with different strategies for the accumulation of salts were investigated. The objects of the study were euhalophytes (Salicornia perennans, Suaeda salsa, Halocnemum strobilaceum), a crynohalophyte (Limonium gmelinii) and a glycohalophyte (Artemisia santonica). The euhalophytes S. perennans and S. salsa belong to plants of the halosucculent type, while the other three species represent the xerophilic type. Larger cells with a great number of chloroplasts, a high content of membrane glycerolipids and unsaturated C18:3 fatty acid and smaller pigment and light-harvesting complexes characterize the features of euhalophytes with a succulent leaf type. Therefore, thefeatures of the halophyte photosynthetic apparatus structure are closely related to its functional indicators and are defined by a strategy in both the accumulation of salts and the method of water regime regulation. Keywords: chlorophyll, lipids and fatty acids, photosynthetic apparatus, ultrastructure of chloroplast

Development of methods ensuring balanced budgets in the medium term

Purpose: The study aims to identify the prospects for the application of modern methods of balancing the budgets of the constituent entities of the Russian Federation. Design/Methodology/Approach: The formation of balanced budgets of the constituent entities of the Russian Federation is intended to provide funding for priority expenditures of the regions effectively, predetermining the need to identify the features of the implementation of scientific theories about the balance of budgets, to highlight the problems of the budget legislation of the Russian Federation and to determine the prospects for the use of traditional and new market methods of regulating the basic parameters of budgets. Findings: Authors grounded the need for complex application of methods of balancing budgets for the main parameters to increase tax and non-tax revenues, the formation of expenses regarding their optimization and efficiency, weighted debt policy, improving intergovernmental relations. The authors recommended the development of standards for applying methods of balancing budgets. Practical implications: The results of the study can be considered in the practice of forming the basic parameters of the budgets of the constituent entities of the Russian Federation in the context of limited budget funds to strengthen budget revenues. Originality/Value: The main contribution of this study is to justify the complexity of the application of methods of balancing budgets, as well as to shift the emphasis on the regulation of domestic debt relations in the context of economic uncertainty.peer-reviewe

Current problems of modern choice execution: choice theatralization

The article discusses the theoretical aspects of the problem of finding ways to develop choral performance in the conditions of the modern cultural and educational environment. The purpose of the materials presented in the publication is to actualize the appeal to choral theatricalization as an effective means of awakening and developing the interest of students in collective singing activities. The concept of “choral theatricalization” and significant aspects of attracting young people to choral performance are analyzed. The priority is determined by the reliance on the following components of the collective musical and creative activity: perceptual (features of musical perception, empathy, understanding musical information, its semantic and emotional content); communicative (dialogue between performers and authors of a musical work, choirmaster and singers of the choir, members of the choir, the performing team and the audience); interactive (creative interaction between all participants of the artistic and creative process).В статье рассматриваются теоретические аспекты проблемы поиска путей развития хорового исполнительства в условиях современной культурно-образовательной среды. Целью представленных в публикации материалов является актуализация обращения к хоровой театрализации как эффективному средству пробуждения и развития интереса учащейся молодежи к коллективной певческой деятельности. Анализируются понятие «хоровая театрализация» и значимые аспекты привлечения молодежи к хоровому исполнительству
