Subject. The article considers financial regulation through the use of tax mechanisms. Objectives. The aim of the study is to evaluate European and Ukrainian practices of fiscal incentives for farming through fiscal instruments with VAT playing the key role. Methods. In the study we employed economic and statistical research methods, like monographic, comparison, scientific generalization. Results. Based on the analysis of VAT implementation on farmers in developed countries in Europe we substantiated the conclusion about its focus on simplifying the tax procedures and eliminating the negative impact on operations of economic entities. Special tax treatment (including VAT collection) is mainly used to streamline tax relations, taking into account the specifics of farming, rather than to improve the financial support to farms. We revealed that in the Ukrainian practice its main task is financial support to agricultural production. Conclusions and Relevance. The experience of developed European countries on the use of special tax regimes and taxation procedures should serve as a model for Ukraine. Financial incentives for agricultural production development should be directly supported by the State, and special tax treatment and tax administration should be focused on streamlining tax relations in the region, based on the practice of developed European countries such as UK, Germany, Italy and France.

Subject. This article considers the system of strategic planning documents as a scientific and practical basis for achieving the goal of improving the well-being of the population by increasing investment activity and the competitiveness of the regional economy. Objectives. The article aims to explore the possibilities and features of the application of marketing technologies in the effective management of the development of the Russian Federation constituent entities. Methods. For the study, we used the methods of general scientific and statistical research, content analysis, and data visualization techniques. Results. The article presents a brief analytical overview of strategic planning documents and analysis of the possibilities of using modern marketing tools. The article also highlights the use of marketing to improve the competitiveness of a particular area, taking into account the experience of leader regions. Conclusions. Modern strategic documents regulating the development of regions have some contradictions in terms of the characteristics of the state of the Russian Federation subjects concerning various indicators of development. The problems and practicalities of addressing them need to be more clearly identified. The results of the study can be used by regional and municipal authorities to develop plans to improve the strategic management of the areas' development.

The paper presents the results of tests aimed at evaluating the surface textures of samples manufactured from material based on 316L stainless steel. The analysis of the surface topography was conducted based on the classical approach in accordance with the current standard and with the use of multiscale methods; i.e., wavelet transformation and geometric via curvature. Selective laser melting 3D printing technology was used to produce samples for surface testing. Furthermore, additional assessment of surfaces created as result of milling was conducted. Statistical research demonstrated a differentiation in the distribution of particular morphological features in certain ranges of the analyzed scales.

It is commonly thought that the promotion of faculty members is affected by their research performance. The current study is unique in examining how academic faculty members perceive the harm or damage to academic appointment and promotion processes, as a direct effect of student evaluations as manifested in teaching surveys. One hundred eighty two questionnaires were collected from senior faculty members at academic institutions. Most respondents were from three institutions: Ariel University, Ben Gurion University, and the Jezreel Valley College. Qualitative and statistical research tools were utilized, with the goal of forming a model reflecting the effect of the harm to academic appointment and promotion processes, as perceived by faculty members. The research findings show that the lecturers find an association that causes harm to their promotion processes as a result of student evaluations. Assuming that students' voices and their opinion of teaching are important – the question is how should these evaluations be treated within promotion and appointment processes: what and whom do they indicate? Do they constitute a reliable managerial tool with which it is possible to work as a foundation for promotion and appointment processes – or should other tools be developed, unrelated to students' opinions?

Consider a gene expression array study comparing two groups of subjects where the goal is to explore a large number of genes in order to select for further investigation a subset that appear to be differently expressed. There has been much statistical research into the development of formal methods for designating genes as differentially expressed. These procedures control error rates such as the false detection rate or family wise error rate. We contend however that other statistical considerations are also relevant to the task of gene selection. These include the extent of differential expression and the strength of evidence for differential expression at a gene. Using real and simulated data we first demonstrate that a proper exploratory analysis should evaluate these aspects as well as decision rules that control error rates. We propose a new measure called the mp-value that quantifies strength of evidence for differential expression. The mp-values are calculated with a resampling based algorithm taking into account the multiplicity and dependence encountered in microarray data. In contrast to traditional p-values our mp-values do not depend on specification of a decision rule for their definition. They are simply descriptive in nature. We contrast the mp-values with multiple testing p-values in the context of data from a breast cancer prognosis study and from a simulation model.
