FINANCIAL SUPPORT AND FORECASTING OF FOOD PRODUCTION USING ECONOMIC DESCRIPTION MODELING METHODS

The article considers the financial programs used by the state to support food production based on the use of methods of economic descriptive modeling. It is established that the interpretation of the essence and strategy of financing in practice has quite different approaches. It has been proven that the formation of an effective system of financing food production involves the relationship and effective redistribution between different sources of financial resources. It is substantiated that agriculture has all the prerequisites for productivity growth provided that investment in the Ukrainian agricultural sector increases and effective budget financing. In this regard, the features of food production based on the use of descriptive modeling capabilities using the software package Statgraphics XVII Centurion. Because of the analysis, it is established that the main parametric criterion, which depends on the level of food production in the country as a whole and individual regions, determines the indicator of agricultural production, quantitative parameters of which are taken as a basis for calculating self-sufficiency, import coverage, calories, consumption, profitability and others. Estimation of this indicator by means of modeling allowed to make the forecast of dynamics of change of its volumes for the next twelve time periods for the purpose of preliminary definition of level of food production. For this purpose, the economic and mathematical tools of estimation of forecast dynamics of change of volumes of agricultural production for the future periods are used. Modeling of the indicator of agricultural production per person per year was carried out by research on the normality of distribution using Kolmogorov —Smirnov, Anderson — Darling compliance tests and a modified Kolmogorov — Smirnov test. According to the results of comparative analysis of seventeen different models and five compliance tests, it was found that most of the statistical tests are quadratic model, based on which the projected volumes of agricultural production per person per year and calculated for each forecast year (period) with a reliability of 95% lower and upper limits of the studied indicator. It is established that by 2030 in Ukraine with a high probability the growth trend of agricultural production will continue, and at a high rate. The article outlines the benefits of using economic modeling methods in the study of a particular problem.

Monitoring of Elastoplastic Fracture Behavior of HSLA Steel Using Acoustic Emission Testing

The present study explores using acoustic emission testing (AE) to monitor the elastoplastic fracture toughness (JIC) of high-strength, low-alloy (HSLA) steel in two different orientations. Acoustic emission signals generated during the tests were found to be higher during bulk yielding upon initial loading, after which they decreased during intermediate loading before increasing again. The acoustic emission signals generated were used to correlate with the JIC values determined from unloading compliance tests. The point of crack initiation estimated by AE is lower than that determined by the unloading compliance tests. Beyond the point of crack initiation determined by AE, the acoustic emission signals generated increased rapidly, which is attributed to crack growth. The results of AE during crack initiation are supported by the peak amplitude of the acoustic emission signals. The possibility of using AE data to estimate fracture toughness values has also been explored for HSLA steel.

Impacts of Leader Humility Between Authority and Trustworthiness on Compliance: Tests of Three-Way Interaction

This study aims to examine how leader humility affects the relationship between authority and trustworthiness, and its effect on subordinate compliance. This study further addresses the reliability and validity issue to advance the measurement of humility; 300 participants consisting of leader-subordinate dyads of 50 leaders and 250 subordinates contributed to the data collections. This study found that both trustworthiness and authority have impact on subordinate compliance. Through three-way moderating analysis, this study further revealed that a leader’s high humility, along with high trustworthiness under high authority results in the highest compliance, whereas a leader’s high humility combined with low trustworthiness under low authority leads to the lowest compliance. Moreover, although a leader’s personal background showed no relationship with the degree of leader humility, divergent combinations of leader-subordinate backgrounds were found to affect the degree of humility. Based on our findings, we propose that to effectively increase compliance, leader humility must be viewed as a strength when combined with high trustworthiness in high authority situations. This study may prompt future research in exploring humility in the context of virtue versus power, and the effects of humility in leadership. The implications of these findings for both theory and practice are also discussed.

Evaluating FAIR maturity through a scalable, automated, community-governed framework

Transparent evaluations of FAIRness are increasingly required by a wide range of stakeholders, from scientists to publishers, funding agencies and policy makers. We propose a scalable, automatable framework to evaluate digital resources that encompasses measurable indicators, open source tools, and participation guidelines, which come together to accommodate domain relevant community-defined FAIR assessments. The components of the framework are: (1) Maturity Indicators – community-authored specifications that delimit a specific automatically-measurable FAIR behavior; (2) Compliance Tests – small Web apps that test digital resources against individual Maturity Indicators; and (3) the Evaluator, a Web application that registers, assembles, and applies community-relevant sets of Compliance Tests against a digital resource, and provides a detailed report about what a machine “sees” when it visits that resource. We discuss the technical and social considerations of FAIR assessments, and how this translates to our community-driven infrastructure. We then illustrate how the output of the Evaluator tool can serve as a roadmap to assist data stewards to incrementally and realistically improve the FAIRness of their resources.

Between facts and norms: Testing compliance with Article 8 ECHR in immigration cases

The European Court of Human Rights plays a subsidiary role in the protection of the rights and freedoms set forth in the Convention. To enable national authorities to perform their primary role, it is important that the Court offers sufficient guidance on the interpretation of the Convention. It has already been argued that the case law of the Court on the right to respect for family life in immigration cases, lacks consistency in terms of procedural and substantive protection. The inconsistency in the case law is mostly the case in the admission and regularisation case law. This manifests itself in specific issues including the determination of whether an interference has occurred as well as the court’s determination of the best interests of the child. Consequently, the case law difficult to apply by national authorities which leads to widely diverging practices by the Contracting Parties. The objective of this article is to outline the differences and inconsistencies in the different forms of immigration cases and the corresponding compliance tests of the Court. The article aims to offer a solution that would enable both the Court and the Contracting Parties to differentiate the level of protection that is offered by Article 8 in immigration cases, while providing sufficient guidance to national decision-making authorities and judiciaries so that they can efficiently and effectively exercise the primary role they play in the protection of the right to respect for family life in immigration cases.

Selected aspects of proper integration between ERTMS/ETCS on-board and trackside devices.

Achieving the interoperability of the European rail system requires many measures to unify technical solutions as well as regulations in each Member State. However, there is a possibility of some incompatibilities between individual subsystems despite generating them in accordance with unified applicable requirements. It is possible that the interoperable rolling stock will not be able to move freely over the interoperable railway line due to some incompatibilities and differences in the versions of the installed firmware in the ERTMS/ETCS system devices. In connection with the above the correct integration of rail vehicles with track-side equipment should be examined by means of tests under operating conditions. The article presents compliance tests of the correct integration of the on-board subsystem with the track-side subsystem which are carried out by the Railway Research Institute.
