Purpose This paper accounts for, and reflects upon, the research design and the methodological approach adopted in ethnographic research with young people. In particular, the purpose of this paper is to reinforce the significance of conducting qualitative participatory and innovative methods with young people, alongside the value of rapport building. Design/methodology/approach Qualitative participatory methods are understood as the most appropriate way to empower and respect young people in the research process. Alongside such methods the ethnographic nature of the research is discussed in conveying the importance of rapport building with young people in the field. In doing so the paper examines a number of important considerations when conducting youth research. Findings The triangulation of qualitative methods was fundamental in exploring and understanding young people’s lives in each locality and allowed for deep and meaningful explorations of specific themes. The additional and complementary methods employed alongside traditional methods were particularly suited to understanding young people’s everyday lives, as complex experiences are not always conveyed through traditional methods alone. Conducting participatory methods produced narratives around safety, security and governance in public places. Originality/value Being reflexive and adapting to a research setting in order to enhance the process of building and maintaining trust with young people is the most important facet when conducting youth research. Giving careful consideration to the impact of a researcher’s presence in the field needs to be carefully navigated.

Purpose. Under the conditions of strengthening of the destructive effects of the global economic crisis and the growing number of risks of agribusiness, there is a problem in finding the ways to improve accounting and analytical support as the only reliable source of the relevant and accurate information needed for economic security management. The purpose of the article is to substantiate the directions to improve the analytical basis as a component of accounting and analytical support of economic security management of the agricultural enterprises. Methodology / approach. The methodological basis of the research is a dialectical method of cognition of the complex economic phenomena. Consideration of the analytical support of complex management processes took place using a systematic approach, analysis and synthesis. Using an integral approach, a methodology for assessing and analyzing economic security of the agricultural enterprises is developed. This methodology approach includes the parameters of financial, social, resource and environmental security. Results. The analysis of the theoretical and methodological foundations of accounting and analytical support of economic security management showed a variety of the approaches to the choice of the indicators that describe the level of economic security. The situation is complicated by the need to analyze the information that may be relevant for management decisions in conditions of uncertainty. Under these conditions, it is proposed to implement a model of analytical support for economic security management under conditions of uncertainty and growing risks and threats to the business environment of the agricultural enterprises, which should be based on the use of general economic, statistical, integral and econometric approaches. It is determined that in the process of counteracting the risks and threats of the external and internal environment of the agrarian business the use of the integral methods of assessing economic security of the agricultural enterprises becomes crucial. It is substantiated that the most expedient in terms of achieving strategic goals of the enterprise, maintaining its competitive advantages and ensuring sustainable development is the use of integral assessment of economic security, which should be based on a synergistic approach to analysis of 25 indicators of financial, social, resource and environmental components. The approach was tested on the example of 24 agricultural enterprises of Kharkiv region (Ukraine) of crop specialization (2019). The model is also used to analyze the dynamics of the level of economic security under conditions of individual agricultural enterprises of different organizational and legal forms of management (2014–2019).  Originality / scientific novelty. According to the results of the research, a methodological approach to determination of the integral level of economic security of the agricultural enterprises has been improved, based on the impact of the indicators of its individual components, which, at the same time, improves the analytical support of economic security management and strengthens verification, forecasting, preventive, planning and control functions of accounting and analytical support of management mechanisms. Practical value / implications. The practical significance of the proposed approaches consists of the possibility of positioning the enterprises in terms of optimal, satisfactory, shaky and crisis economic security zones, as well as analyzing the dynamics of the integral level of economic security, which takes into consideration the causal relations of the key areas of the agrarian business under conditions of uncertainty.

Budget Execution

Further improvement of financial relations at the local level and the development of local budgets take place in the context of financial decentralization. This implies strengthening the role of local governments in attracting necessary financial resources to ensure socio-economic development of territories. The purpose of this paper is to identify the impact of decentralization on the state of local budgets and to develop a scientific and methodological approach to assessing the level of financial decentralization of local budgets using the example of Ukraine for 2010–2019. The developed methodology consists of six successive stages. A comparative analysis of the dynamics of indicators of local budget execution in Ukraine in terms of revenues, expenditures and transfers using an integrated index obtained through taxonomic analysis is conducted. As a result of evaluating the effectiveness of the basic principles of financial decentralization, the expediency of calculating the integrated index of local budget financial decentralization is substantiated. This index is formed using intermediate indicators of autonomy to cover expenses and generate income both on the basis of own sources and taking into account the received state transfers for the implementation of their own and delegated powers of local governments. The implementation of the proposed method allow one to assess the levels of financial decentralization of local budgets to establish the degree of financial autonomy and financial self-sufficiency of the territories. The results obtained should be considered when determining the effectiveness of financial support for local budgets in the process of socio-economic development of regions.

Forecast Time

To forecast time series data, two methodological frameworks of statistical and computational intelligence modelling are considered. The statistical methodological approach is based on the theory of invertible ARIMA (Auto-Regressive Integrated Moving Average) models with Maximum Likelihood (ML) estimating method. As a competitive tool to statistical forecasting models, we use the popular classic neural network (NN) of perceptron type. To train NN, the Back-Propagation (BP) algorithm and heuristics like genetic and micro-genetic algorithm (GA and MGA) are implemented on the large data set. A comparative analysis of selected learning methods is performed and evaluated. From performed experiments we find that the optimal population size will likely be 20 with the lowest training time from all NN trained by the evolutionary algorithms, while the prediction accuracy level is lesser, but still acceptable by managers.

The Impact

To the article the results of the theoretical and experimental researches are given on questions of estimates of the dynamic rate effect of raindrop impact on soil. The aim of this work was to analyze the current methods to determine the rate of artificial rain pressure on the soil for the assessment of splash erosion. There are the developed author’s method for calculation the pressure of artificial rain on the soil and the assessment of splash erosion. The study aims to the justification of evaluation methods and the obtaining of quantitative characteristics, prevention and elimination of accelerated (anthropogenic) erosion, the creation and the realization of the required erosion control measures. The paper considers the question of determining the pressure of artificial rain on the soil. At the moment of raindrops impact, there is the tension in the soil, which is called vertical effective pressure. It is noted that the impact of rain drops in the soil there are stresses called vertical effective pressure. The equation for calculation of vertical effective pressure is proposed in this study using the known spectrum of raindrops. Effective pressure was 1.4 Pa for the artificial rain by sprinkler machine «Fregat» and 5.9 Pa for long distance sprinkler DD-30. The article deals with a block diagram of the sequence for determining the effective pressure of rain drops on the soil. This diagram was created by the author’s method of calculation of the effective pressure of rain drops on the soil. The need for an integrated approach to the description of the artificial rain impact on the soil is noted. Various parameters characterizing drop erosion are considered. There are data about the mass of splashed soil in the irrigation of various irrigation machinery and installations. For example, the rate (mass) of splashed soil was 0.28…0.78 t/ha under irrigation sprinkler apparatus RACO 4260–55/701C in the conditions of the Ryazan region. The method allows examining the environmental impact of sprinkler techniques for analyzes of the pressure, caused by raindrops, on the soil. It can also be useful in determining the irrigation rate before the runoff for different types of sprinkler equipment and soil conditions.

The paper analyses specific features of sociological data circulation in a public space during an election campaign. The basic components of this kind of space with regard to sociological research are political actors (who put themselves up for the election), voters and agents. The latter refer to professional groups whose corporate interests are directly related to the impact on the election process. Sociologists can also be seen as agents of the electoral process when experts in the field of electoral sociology are becoming intermingled with manipulators without a proper professional background and publications in this field. In a public space where an electoral race is unfolding, empirical sociological research becomes the main form of obtaining sociological knowledge, and it is primarily conducted to measure approval ratings. Electoral research serves as an example of combining the theoretical and empirical components of sociological knowledge, as well as its professional and public dimensions. Provided that sociologists meet all the professional requirements, electoral research can be used as a good tool for evaluating the trustworthiness of results reflecting the people’s expression of will. Being producers of sociological knowledge, sociologists act in two different capacities during an election campaign: as analysts and as pollsters. Therefore, it is essential that the duties and areas of responsibility for professional sociologists should be separated from those of pollsters. Another thing that needs to be noted is the negative influence that political strategists exert on the trustworthiness of survey findings which are going to be released to the public. Using the case of approval ratings as an illustration, the author analyses the most common techniques aimed at misrepresenting and distorting sociological data in the public space. Particular attention is given to the markers that can detect bogus polling companies, systemic violations during the research process and data falsification.

With the advances in networking technologies, robots can use the almost unlimited resources of large data centers, overcoming the severe limitations imposed by onboard resources: this is the vision of Cloud Robotics. In this context, we present DewROS, a framework based on the Robot Operating System (ROS) which embodies the three-layer, Dew-Robotics architecture, where computation and storage can be distributed among the robot, the network devices close to it, and the Cloud. After presenting the design and implementation of DewROS, we show its application in a real use-case called SHERPA, which foresees a mixed ground and aerial robotic platform for search and rescue in an alpine environment. We used DewROS to analyze the video acquired by the drones in the Cloud and quickly spot signs of human beings in danger. We perform a wide experimental evaluation using different network technologies and Cloud services from Google and Amazon. We evaluated the impact of several variables on the performance of the system. Our results show that, for example, the video length has a minimal impact on the response time with respect to the video size. In addition, we show that the response time depends on the Round Trip Time (RTT) of the network connection when the video is already loaded into the Cloud provider side. Finally, we present a model of the annotation time that considers the RTT of the connection used to reach the Cloud, discussing results and insights into how to improve current Cloud Robotics applications.
