Currently, agricultural science and practice has a large amount of experimental data that need to be taken into account in the development of new technological processes and working bodies. Therefore, there is a need to design technical processes in order to identify their effectiveness. In this regard, the use of methods of synthesis of technological processes based on the characteristics of tillage, seeding and production system of the economy, in which it is necessary to implement the projected process. In the General statement of the problem, the design of technological processes is one of the complex problems with the following characteristic feature: lack of knowledge about the methods of designing technological processes, suitable for system - structural modeling and algorithmization of design processes. To overcome this incompleteness, a systematic approach is needed. The system approach proceeds from the fact that the specificity of complex objects and processes is not limited to the features of its constituent parts and elements, but lies in the nature of relationships and relationships between them. In this paper, the design methodology is based on the formulated fundamental assumptions and principles of the whole system of more specific statements, revealing the structure and content of design operations, the synthesis of the choice of solutions. The principles of technological compatibility and emergence suitable for system-structural analysis of complex technical means and technological processes, consisting of statements having a hierarchical structure, where the degree of detail of the goals from level to level increases, and the approval of the last level determines the direction of the search for the optimal solution to the problem.

Market Relations

In the conditions of market relations, agricultural enterprises begin to independently focus on the recommendations of agricultural science using their own experience and choose the necessary machines and implements for crop production technologies that meet the requirements for productivity, reliability and economic capabilities of farms. In agricultural science and practice, a large number of experimental factors have accumulated, which are taken into account when designing new technological processes and working bodies. Currently, in connection with the automation of design, there is an urgent need to comprehend the accumulated experience and build the foundations of the theory of designing technologies and machines, revealing the basic laws of the design process. So, based on the essence of the systemic approach, a methodology has been developed, where, due to deductive generalization of the results obtained by agricultural science and practice, that is, «top — down» using the formed principles of the whole system and more specific statements that reveal the structure and content of design solutions. The structure of the structure of the principle of compatibility is described, which is characterized by internal integrity, due to the interconnectedness of the principle and statements of various levels.

Feedback Interventions

Purpose This paper aims to extend the argument of DeNisi & Smith Sockbeson, who called to bridge the gap between feedback-seeking and feedback-giving research. The paper pushes their argument further by suggesting that future feedback research should systematically adopt a dyadic and dynamic approach to enhance the understanding of feedback episodes. Design/methodology/approach This paper reviews previous empirical work in the feedback domain and develops conceptual arguments for linking feedback-seeking and feedback intervention research. Findings Drawing upon previous work, the authors conclude that the current depiction of feedback processes in the literature might have been overly static and one-sided. Furthermore, it is argued that feedback research might have not kept up to date with recent conceptual and methodological developments in dyadic organizational behavior research. Research limitations/implications This paper builds on the argument of DeNisi & Smith Sockbeson, in turn contributing to a more complete picture of how feedback processes unfold in organizations. While this paper profiles a few studies that have begun to bridge the disconnect between feedback-seeking and feedback-giving research, one of its limitations is that it does not adopt a systematic approach in reviewing all potential methodologies. Originality/value This paper provides a first step toward studying feedback episodes as dyadic and dynamic processes. In doing so it helps solving one of the long-standing puzzles in management research namely why feedback interventions are sometimes detrimental to performance.

The Russian Federation

Agriculture in the Russian Federation is fundamental to the country’s economic performance, living standards, the wellbeing of people and state safety. Considerations relating to food security, prospects of and challenges before plant breeding in the Siberian Federal District (SFD), the largest agricultural area of the Russian Federation, are provided in the article. The agricultural area used in the SFD is about 50 million hectares and accounts for 13 % of the country’s gross grain production. The need for the introduction of modern molecular biological methods, bioengineering and IT technology is demonstrated and discussed. As Russia as a whole, Siberia is largely engaged in unpromising extensive farming practices, which rely on natural soil fertility, and this factor should be taken into account. Another issue is noncompliance with intensive farming technologies used for cultivating new-generation commercial cultivars. Although capital investments in plant breeding are the most cost effective investments in crop production, breeders’ efforts remain underfunded. The article explains the need for fundamental reform in this economic sector: the recognition of plant breeding as being a fundamental science; a fair increase in its funding; the development of a breeding strategy, nationally and regionally; the further expansion of the network of the Breeding Centers; the re-establishment and improvement of the universities’ departments specialized in plant breeding and seed production; having more state-funded places in the universities for training plant breeders to be able to maintain and cement the country’s advanced position in plant breeding and to develop new globally competitive next-generation cultivars of main crops. Should these issues be ignored, all the problems that have accumulated to date will lead to risks of long-term instability in this economic sector. The need for the careful preservation of continuity in plant breeders and plants being bred is stated. The regulatory functions of the state and agricultural science in plant breeding, plant industry and seed production are considered.

When performing various technological operations in crop production, the working bodies of tillage equipment in contact with the soil wear out under the influence of an abrasive environment. (Research purpose) The research purpose is in theoretical substantiation for a method for quantifying the wear capacity of soils with different abrasive characteristics. (Materials and methods) The article presents the evaluation of the abrasive ability of the soil by the wear of a steel rod vertically immersed in the soil and moving translationally. Authors used the standard rod of steel St0; geometric parameters of the worn rod are diameter d = 25-30 millimeters, height h = 250 millimeters; dynamic characteristics during the test are moving speed V = 3 kilometers per hour, distance of movement L = 100 meters. The worn rod sinks to a certain depth, moves in the soil at a constant speed. A device was used to determine the abrasive characteristics of the soil. (Results and discussion) The numerical characteristic of the wear capacity of the soil was determined as the physical value of the wear of the standard worn rod when moving in the soil as A=Q/L, grams per meter. The lower the value of this ratio, the less abrasive components are in the soil; based on the wear data of a standard rod, it is possible to obtain a characteristic of the wear capacity of various soils. (Conclusions) The proposed method allows us to determine the abrasive and wear characteristics of various types of soils. The results of the study make it possible to install working bodies on tillage machines in accordance with the type and wear capacity of the soil in which they will work, which will reduce the cost of their manufacture and increase the efficiency of the use of equipment.

Purpose Diverse factors may influence travelers when choosing a hotel. Even though breakfast is often commented on in hotel and booking sites, its relative role in hotel selection is rarely studied. This paper aims to determine which attributes clients consider essential regarding the option towards a hotel and their hierarchy namely of breakfast. Design/methodology/approach A systematic review was performed in Scopus, ISI-Web of Science and Google Scholar, including relevant original manuscripts published in all languages between 1998 and 2018. Findings Out of 337 initial references, 25 manuscripts were included. Features related to facilities and services were considered in most manuscripts with 21 and 20 citations, respectively, as being the more relevant factors in hotel selection. Room and accommodation were ranked first as the most important characteristic regarding the option for a hotel, whereas breakfast was only referred to in two articles, published in 2015 and 2017, rated in the tenth and fourth positions, respectively. Research limitations/implications Breakfast seems to be addressed in recent published manuscripts, what may reflect a trend toward its evaluation in travelling experiences. More studies should address the relevance of breakfast and food to (diverse type of) costumers, and managers should also consider these factors when advertising their hotels. Originality/value To the best of the authors’ knowledge, this is the first systematic approach to this question, emphasizing the apparent contradiction of breakfast being often cited in booking sites and not adequately studied in tourism research.
