Model of methods of forming biological picture of the world of secondary school pupils

Introduction: the problem of development of a model of methods of forming the biological picture of the world of pupils as a multicomponent and integrative expression of the complete educational process is considered in the article. It is stated that the results of the study have theoretical and practical importance for effective subject preparation of senior pupils based on acquiring of systematic and generalized knowledge about wildlife. The correspondence of the main idea of the article to the scientific profile of the journal "Integration of Education" determines the choice of the periodical for publication. Materials and methods: the results of the analysis of materials on modeling of the educational process, on specific models of the formation of a complete comprehension of the scientific picture of the world and its biological component make it possible to suggest a lack of elaboration of the aspect of pedagogical research under study. Therefore, the search for methods to overcome these gaps and to substantiate a particular model, relevant for its practical application by a teacher, is important. The study was based on the use of methods of theoretical level, including the analysis of pedagogical and methodological literature, modeling and generalized expression of the model of forming the biological picture of the world of secondary school senior pupils, which were of higher priority. Results: the use of models of organization of subject preparation of secondary school pupils takes a priority position, as they help to achieve the desired results of training, education and development. The model of methods of forming a biological picture of the world is represented as a theoretical construct in the unity of objective, substantive, procedural, diagnostic and effective blocks. Discussion and conclusions: in a generalized form the article expresses the model of methods of forming the biological picture of the world of secondary school pupils and gives a teacher the opportunity to use it in practice of subject preparation of pupils.Peer reviewe

Management accounting of agricultural production: improving planning and standardization of costs in the management information system

The problems of organizing effective management accounting of agricultural production through the widespread use of economic methods, both production management and accounting and management methods and the development of their information functions, are very relevant and necessary. Management accounting in modern times is a universal integrated mechanism for the accounting and management activities of an agricultural organization. The management accounting information system should be oriented towards solving complex issues and making managerial decisions quickly. The purpose of the study is the rationale for rationing, planning and management accounting of costs, their control and analysis of production results in the agricultural management information system. The subject of the study is management accounting, while principles are formulated and new methods for rationing labor, material and biological costs of agricultural production are proposed. A unified nomenclature of cost items has been developed for planning, managerial accounting, analysis and control, both for individual production, accounting and planning objects, as well as for self-supporting units (responsibility centers) and the organization as a whole. For the organization of rationing, planning and management accounting of production costs, the sequence of implementation of special procedures is defined, a unified nomenclature of cost items is developed based on the basic conditions of requirements, which include classification attributes, degree of cost participation in the creation of new products, cost control by hierarchical levels of management. It is concluded that by comparing the actual and planned costs for the production of a particular object of planning and accounting, it is possible to analyze their cause and effect deviations, deviations of the actual marginal income and operating profit of the production of these products from their normative values ​​by changing each specific cost item

Biome changes and their inferred climatic drivers in northern and eastern continental Asia at selected times since 40 cal ka bp

Recent global warming is pronounced in high-latitude regions (e.g. northern Asia), and will cause the vegetation to change. Future vegetation trends (e.g. the “arctic greening”) will feed back into atmospheric circulation and the global climate system. Understanding the nature and causes of past vegetation changes is important for predicting the composition and distribution of future vegetation communities. Fossil pollen records from 468 sites in northern and eastern Asia were biomised at selected times between 40 cal ka bp and today. Biomes were also simulated using a climate-driven biome model and results from the two approaches compared in order to help understand the mechanisms behind the observed vegetation changes. The consistent biome results inferred by both approaches reveal that long-term and broad-scale vegetation patterns reflect global to hemispheric-scale climate changes. Forest biomes increase around the beginning of the late deglaciation, become more widespread during the early and middle Holocene, and decrease in the late Holocene in fringe areas of the Asian Summer Monsoon. At the southern and southwestern margins of the taiga, forest increases in the early Holocene and shows notable species succession, which may have been caused by winter warming at ca. 7 cal ka bp. At the northeastern taiga margin (central Yakutia and northeastern Siberia), shrub expansion during the last deglaciation appears to prevent the permafrost from thawing and hinders the northward expansion of evergreen needle-leaved species until ca. 7 cal ka bp. The vegetation climate disequilibrium during the early Holocene in the taiga-tundra transition zone suggests that projected climate warming will not cause a northward expansion of evergreen needle-leaved species

Multiplex Analysis of Serum Cytokine Profiles in Systemic Lupus Erythematosus and Multiple Sclerosis

Changes in cytokine profiles and cytokine networks are known to be a hallmark of autoimmune diseases, including systemic lupus erythematosus (SLE) and multiple sclerosis (MS). However, cytokine profiles research studies are usually based on the analysis of a small number of cytokines and give conflicting results. In this work, we analyzed cytokine profiles of 41 analytes in patients with SLE and MS compared with healthy donors using multiplex immunoassay. The SLE group included treated patients, while the MS patients were drug-free. Levels of 11 cytokines, IL-1b, IL-1RA, IL-6, IL-9, IL-10, IL-15, MCP-1/CCL2, Fractalkine/CX3CL1, MIP-1a/CCL3, MIP-1b/CCL4, and TNFa, were increased, but sCD40L, PDGF-AA, and MDC/CCL22 levels were decreased in SLE patients. Thus, changes in the cytokine profile in SLE have been associated with the dysregulation of interleukins, TNF superfamily members, and chemokines. In the case of MS, levels of 10 cytokines, sCD40L, CCL2, CCL3, CCL22, PDGF-AA, PDGF-AB/BB, EGF, IL-8, TGF-a, and VEGF, decreased significantly compared to the control group. Therefore, cytokine network dysregulation in MS is characterized by abnormal levels of growth factors and chemokines. Cross-disorder analysis of cytokine levels in MS and SLE showed significant differences between 22 cytokines. Protein interaction network analysis showed that all significantly altered cytokines in both SLE and MS are functionally interconnected. Thus, MS and SLE may be associated with impaired functional relationships in the cytokine network. A cytokine correlation networks analysis revealed changes in correlation clusters in SLE and MS. These data expand the understanding of abnormal regulatory interactions in cytokine profiles associated with autoimmune diseases
