Determination of the Risk Function for Survivors Using Beta Pert Method In emergency at sea the most important is to start the rescue action as fast as possible, whereas the decision to terminate the action, in case the survivors have not been found, is made by the coordinator on the basis of his practical experience. To estimate the level of risk it is necessary to face the problem of lack of credible statistical data. The paper presents a new concept which allow to calculate the risk, taking into account data uncertainty. The method and probability model are presented and discussed.

The article discusses approaches to minimizing financial losses by diversifying financial risks, it is proposed to improve the mechanism for diversifying financial risks, which should consist of the following stages: 1) Formation by the financial and economic department of the subject (enterprise, bank, investment company, etc.) of the input data, depending on the type of activity, among which the most typical are: volumes and structure of credit resources, their price, borrowing terms, loan currency, volumes and structure of product exports and imports of goods, export and import currencies, duration of the production cycle, volumes and structure of securities portfolio, types of securities, profitability indicators, types and the level of expenses. 2) Determination of the types of financial risks faced by an economic entity, and its measurement for each type, as well as the level of losses suffered by an economic entity in previous periods, in order to assess the feasibility of diversifying financial risks. 3) Determination of the most effective diversification options for an economic entity by comparing the costs of implementing possible options and the resulting from diversification by reducing the level of risk. 4) Assessment of other options for minimizing losses from financial risks that the entity can apply and which can be grouped as follows: hedging risks, limiting and compensating risks. 5) Calculation of financial implications for an economic entity from the introduction of financial risk diversification To do this, it is necessary to compare the costs and the expected effect of diversification, that is, will the level of risk decrease, or what will be the maximum possible financial losses. Calculated on the basis of statistical data, the values of the coefficient of variation of deposit and lending rates, as well as the exchange rate of UAH to foreign currencies. A methodology for assessing the level of possible financial losses and the effectiveness of the process of diversifying financial risks is proposed. The introduction of a mechanism for diversifying financial risks will help reduce financial losses by economic entities, which in turn will improve the overall financial results of their activities.

The relationship between risk-taking behavior, alcohol consumption and negative alcohol-related consequences is well known. The current analyses were conducted to investigate whether alcohol mixed with energy drink (AMED) is related to risk-taking behavior and if there is a relationship between the amount of energy drink mixed with alcohol consumed, risk-taking behavior and negative alcohol-related consequences. Data from N = 1276 AMED consuming students from the Netherlands, UK and Australia who completed the same survey were evaluated. The analysis revealed that, compared to AMED occasions, on alcohol only (AO) occasions significantly more alcohol was consumed and significantly more negative alcohol-related consequences were reported. On both AO and AMED occasions, there was a strong and positive relationship between amount of alcohol consumed, level of risk-taking behavior and number of reported negative alcohol-related consequences. In contrast, the level of risk-taking behavior was not clearly related to energy drink consumption. Across risk-taking levels, differences in the amount of energy drink consumed on AMED occasions did not exceed one 250 mL serving of energy drink. When correcting for the amount of alcohol consumed, there were no statistically significant differences in the number of energy drinks consumed on AMED occasions between the risk-taking groups. In conclusion, alcohol consumption is clearly related to risk-taking behavior and experiencing negative alcohol-related consequences. In contrast, energy drink intake was not related to level of risk-taking behavior and only weakly related to the number of experienced negative alcohol-related consequences.

Studying the historical facts of past wars and armed conflicts and natural and man-made emergencies, today in the Republic of Kazakhstan one of the most important security issues is the preparation and organization of the evacuation of the population from possible dangerous zones, taking into account the emergence of new threats to the country’s security. The paper presents an algorithm for constructing universal scales of the distribution function of opportunities by types of support and rebuilding them into subject scales using display functions. The purpose of the paper is to determine the integral indicators characterizing the possibility of accommodation of the evacuated population and the impact on resources during relocation. On the subject scales of cities and districts of the region, indicators of the possibility of relocation of a certain amount of the evacuated population by types of support and indicators characterizing the impact on the district’s resources during resettlement of a certain amount of the evacuated population are determined. It was concluded that the use of integrated indicators allows the selection of areas to accommodate the evacuated population without the use of statistical data, in conditions of incomplete and inaccurate information. The presented method does not replace traditional methods based on classical methods of territory assessment by the level of life sustenance, but also allows their reasonable combination with the experience of specialists in this field, taking into account the incompleteness, uncertainty, and inconsistency of the initial data of the study area, which does not allow the application of existing methods.

The Effect of Product Quality and Price on Purchase Intention for Selancar Rice (Case Study on Housewives in Kota Baru Jalan Kapten Satar RT. 10 RW. 03 Lahat). This research was conducted on housewives located at Jalan Kapten Satar RT 10 RW 03 No. 25 Kelurahan Kota Baru, Lahat District. The research objective was to see the effect of the product and price on buying interest in surfing rice. The regression equation Y = 10.588 + 0.453 X1 + 0.339 X2 + e. Based on statistical data analysis, the indicators in this study are valid and reliable. The individual order of each variable with the most influence is the product quality variable with a regression coefficient of 0.453 then the price variable with a regression coefficient of 0.339. Obtained t count variable product quality (X1) of 2.658> 2.011 and variable price (X2) obtained at 2.905> 2.011. This means that t is greater than t table, then H_0 is rejected and H1 is accepted. Obtained an F calculated value of 7.009> 3.20 so that it can be ignored that there is a simultaneous (joint) influence between product quality (X1) and price (X2) on buying interest (Y) of surfing rice. Analysis of the coefficient of determination of 23% means that there is a very weak relationship between the independent variables and the related variables and the rest is 77%. By other factors that are not discussed in this study.

The deposits of the Kharkov suite of Paleogene of Belarus are the soils formed at the turn of existence and regression of the last sea basin and the final establishment of the continental situation in the territory of the country. They are widely spread in the south of the republic and lie mostly at depths of 100–110 m. In the southeast of Belarus, along the valleys of large rivers, these soils often reach the surface. The latter predetermined their active use as the foundations of structures. This is especially pronounced in the city of Gomel, where a wide development of territories is currently underway, within which these soils lie at depths of less than 10 m. The purpose of the work is to characterize the conditions for the distribution of the soils of the Kharkov suite of Paleogene within the southeast of Belarus and to study the characteristics of their composition and structure. The work is based on the results of the author's field and laboratory studies, which included a description of the outcrops, pits, and well cores; soil sampling; determination of their chemical and mineral, granulometric and microaggregate compositions, moisture characteristics for the classification of clay soils, as well as the results of statistical data processing. The paper presents the typification of the soil strata of the Kharkov suite of Paleogene of the southeast of Belarus, which allowed us to isolate three characteristic sites that differ in terms of their distribution, depth, thickness of the strata and composition of the soils. Nine granulometric sand and clay differences within the isolated areas were identified. The study of chemical-mineral and granulometric compositions of soils made it possible to identify their significant changes, both in area and in the section, which is caused by confinement to various facies zones, frequent migration of the coastline, long and uneven erosion and glacier-exaction destruction. The interrelation of the mineral composition, size and morphology of sandy soil particles is analyzed, it is noted that in all their varieties medium and fine sand fractions differ in the greatest mineral diversity.

Level Of Risk

We investigate, theoretically and experimentally, the effect of competition on risk taking in a contest in which players only decide on the level of risk they wish to take. Taking more risk implies a chance of a higher performance, but also implies a higher chance of failure. We vary the level of competition in two ways: by varying the number of players (2 players versus 8 players), and by varying the sensitivity of the contest to differences in performance (lottery contest versus all-pay auction). Our results show that there is a significant interaction effect between the two treatments, suggesting that players are particularly prone to take more risks if both the number of players and the sensitivity to performance are higher.

Land-use as a part of the earth’s surface used in an unitary manner, constitutes as one of the objects of Real Estate Cadastre in Poland. This register gathers data concerning actual grounds status, buildings and premises. Cadastre is carried out in an informational system on the basis of Geodetic and Cartographic Law and its implementing act. The contents of mentioned legal regulations are very general in terms of capturing and revealing data on ecological land-use. The rules are also related to environmental protection law. It often makes its proper interpretation difficult. In this article, the study aimed to systematize information about recording ecological land-uses in Polish Real Estate Cadastre has been performed. Practical and legal solutions concerning determination of the ecological land-uses coverage have been presented. The authors evaluate an order of individual activities leading to ecological land-use disclosure in cadastral database. The consequences and constraints in enforcing the ownership to land property or its parts where ecological land-use was allocated are analyzed as well. The statistical data in the scope of number and surface area of ecological land-uses in individual provinces have also been demonstrated.

Abstract Within the process of the International Conference on Harmonization (ICH), 2 guidelines were released containing a standardized terminology, a verified model of requirements for the validation of analytical procedures, and some guidance in the practical aspects of conducting validation studies in pharmaceutical analysis. For planar chromatographic procedures, which may be used at different levels either in qualitative identity testing, assays, semiquantitative limit tests, or quantitative determination of impurities, this paper tries to transfer these formal requirements into practical approaches for validation. Basic acceptance criteria for evaluation of validation experiments based on practical experience are proposed. In addition, selected parameters for robustness testing of given procedures and quality assurance of quantitative planar chromatographic testing by control charts is described.
