Abstract A performance genetics model adapted to real-world data of Thoroughbred racing and breeding will be presented. The continuity of ancestry and performance is documented in the annals of pedigree, not as functional counterparts, but as corresponding signs of market value. Pedigree invites chronic misprision of highly diverse genetic resources competing for scarce opportunity in the racing economy, resulting in samples that are often small and of dubious composition. Data is specialized for competing “pedigree analysis” that packages the system of signification to meet market demand for meaning. Given statistical deficits, this data is a necessary inferential asset of the model. The model’s premise is that predictability is optimized if racing performance is defined as the function of an indivisible relation between parents. Statistical data consists of 6-generation ancestries of mares that produced offspring by a subject stallion. Comparison of proportions is used to identify effects resulting from his relation to individual ancestors of the subject mare. Expected performance by the sire’s offspring is defined as the proportion of mares that produced a superior runner by him. Each ancestor of a subject mare also has descendants among the mares that produced offspring by the stallion. For each of those groups, the proportion of mares that produced a superior runner is compared with the stallion’s expected performance using a t-test of statistical significance at the .10 level. Probable effect is further tested by case study involving such variables as racing class, generational distance, sex-linkage, inbreeding, and an ancestor’s pattern of effect across the stallion population. Stallions with the highest prevalence of positive effects are preferred for the subject mare. This model, under the trade name LyonScore®, has been used since 2012 by Werk Thoroughbred Constultants, Inc. as a component of its client services. Table 1: The data, listed in tabular format below, is graphically displayed for actual use on an ancestry tree whose nodes are numbered by relation to a subject mare (“Position”). Each statistical data item in the table is derived from the stud record of a stallion named Distorted Humor and corresponds with an ancestor of a mare named Positively Royal. Each ancestor of this mare is also an ancestor of a group of mares that produced offspring of Distorted Humor and were at least three years of age as of 2019. A proportion of each of those groups of mares produced at least one superior runner. Proportions that differ significantly from Distorted Humor’s expected proportion are so indicated. Only ancestors involving a group of at least 18 mares are considered to have inferential value on statistical grounds. Table 2: The sire Danzig is an ancestor of Positively Royal, along with 75 mares that produced foals by Distorted Humor, only five of which produced a superior runner by him, significantly fewer than expected. However, since Distorted Humor’s dam is by Danzig, the question of generational distance is relevant as a variable to the effect of inbreeding. The table below shows Danzig’s proportional distribution by genetic relation to those 75 mares as indicated by “Position.” Of the 64 mares in descent of Danzig within three generations, three mares produced a superior runner. It’s notable, though, that 2 of 6 mares with the same relation to Danzig as Positively Royal produced superior runners. Since Danzig is the only ancestor with a negative effect, further consideration is warranted. Table 3: In a population that tends to slough off unprofitable genetic resources, overspecialization is the main risk of close inbreeding. Some generational variations of an ancestor’s contribution can turn inbreeding to less specialized effect, but this depends on generational distance. Distorted Humor’s earliest opportunity with mares in descent of Danzig involved offspring closely inbred to Danzig, but later in his career he encountered mares for which variation was more likely. As the table shows, two of six mares descending from Danzig in position 25 (4th generation) produced Distorted Humor’s best runners inbred to Danzig, so it is of some interest that Positively Royal, the subject mare, is also a postion-25 descendant of Danzig. However, that those two mares happen to be full sisters whose breeding has little else in common with that of Positively Royal leaves the question of Distorted Humor’s fitness for this mare less certain than would be preferred.

This paper characterises the directions of innovative activities undertaken by food industry enterprises concerning the manufacturing of food products. Based on the subject literature and secondary statistical data, the status of food industry innovativeness and areas of innovative activities related to implementation of technological and non-technological innovations are presented. The activities of enterprises focus on manufacturing new products in response to the ever-changing needs and expectations of consumers. In particular, the production of so-called functional food (which seeks to promote health, minimise the risk of specific diseases, improve psychophysical fitness, lose weight, etc.) is increasingly extensive. Manufacturers must also improve the technologies and techniques of product manufacturing, packaging and storage.

The article is devoted to the state of the economy of the subject of the agricultural sector – the Toktogul region of Kyrgyzstan, as well as the formation of a land division, which is impossible without an influx of investments and ensuring the availability of monetary resources for agricultural producers. In our time, innovation is becoming the main means of increasing the benefits of economic entities by better meeting market demand and reducing production losses compared to competitors. Despite repeated attempts by the country to create a system of lending to agricultural companies, only a small percentage of them use credit resources. Various state aid schemes support a competitive environment in the money markets and guarantee relatively equal access to them for financial institutions and agricultural enterprises.

Views on the institution of direct democracy have changed during the period of democratic transition. The various advantages and positive effects of direct democracy have been confirmed by the practice of some democratic countries. Its educational and political activation value for society was also noted, without which civil society cannot form. The referendum is especially treated as the purest form of correlation between the views of society and the decisions of its representatives. In a situation where two representative bodies are present – the parliament and the president – a referendum is considered a means of resolving disputes between them in important state affairs. The referendum is nowadays becoming more than just a binding or consultative opinion on a legislative act, especially a constitution. First and foremost, it is important to see the extension of the type and scope of issues that are subject to direct voting. Apart from the traditional, i.e., constitutional changes, polarising issues that raise considerable emotion have become the subject of referenda. Problems of this type include, in particular, moral issues, membership in international organisations, and so-called ‘New Policy’. This article presents the role and importance of the referendum as an institution shaping the democratic systems of the Black Sea Region.

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.

As the COVID-19 epidemic caused new requirements in education, the use of various technologies and materials in science education has gained more importance for sustainability. Among other objectives, the subject of science aims to help students gain skills such as identifying problems, doing research, forming hypotheses, completing experiments, conducting analyses, and reporting the findings. Some of the problems experienced in science education are caused by the lack of tools and equipment. Through augmented reality (AR), a developing technology that is also used in the field of education, a digital layer is superimposed over authentic world images. The main aim of this study is to determine the views of students and teachers regarding augmented reality content developed for science education. The study group consists of 80 seventh-grade students and 4 science teachers. The study adopted a qualitative data collection method so the researchers developed and used semi-structured interview forms for the students and the teachers during the interviews. Both the students and the teachers reported the positive effects of AR practices on improving the understanding of science topics, offering a visual topic introduction, and contributing to the in-class interaction during class hours.

To consider the main directions and extent of influence of ethical groups on political processes in the Republic of Kalmykia.The authors analyzed scientific research on the ethnic identity of the Kalmyk people, as well as media materials and statistical data on the cause and effect of the influence of ethnic groups on regional policy. Seven key areas of influence of the Kalmyks, as a titular nation, on political processes in the region, including through the formation of an ethnic majority among senior positions in the authorities of the subject of the Russian Federation, were identified. The theoretical significance of the study is due to the complex systematization of facts about the influence of the ethnodominating nation of the Republic of Kalmykia on political processes in the region. The practical significance is expressed in the proposal of specific recommendations for partial stabilization of the situation in the Republic.

It should be pointed out that during the interviews most of the experts had positive expectations of ESM. The developers are more generally enthusiastic than the prospective users and affected parties who, especially in respect of the diffusion of ESM into practical application, only show a limited optimism.However, the representatives of the medical profession and the health insurance industry were convinced that ESM might contribute to cost-neutral increases of quality in out-patient and in-patient medicine. But we also understood them to say that they consider other developments in medicine to be overriding, for example, a tendency of general medicine towards a more family-oriented medicine and a reduced emphasis on technology-oriented medicine. In respect of the conception shared by developers as well as potential users that over-enthusiastic expectations should rather be restrained, we consider such a balanced expectation of positive effects of ESM to be adequate to the actual knowledge of the subject.

The study aims at evaluating health-generating function of humor therapy in a hospital ward hosting children suffering from respiratory pathologies. The main scope of this study is to investigate possible positive effects of the presence of a clown on both the clinical evolution of the on-going disease, and on some physiological and pain parameters. Forty-three children with respiratory pathologies participated in the study: 21 of them belonged to the experimental group (EG) and 22 children to the control group (CG). During their hospitalization, the children of the EG interacted with two clowns who were experienced in the field of pediatric intervention. All participants were evaluated with respect to clinical progress and to a series of physiological and pain measures both before and after the clown interaction. When compared with the CG, EG children showed an earlier disappearance of the pathological symptoms. Moreover, the interaction of the clown with the children led to a statistically significant lowering of diastolic blood pressure, respiratory frequency and temperature in the EG as compared with the control group. The other two parameters of systolic pressure and heart frequency yielded results in the same direction, without reaching statistical significance. A similar health-inducing effect of clown presence was observed on pain parameters, both by self evaluation and assessment by nurses. Taken together, our data indicate that the presence of clowns in the ward has a possible health-inducing effect. Thus, humor can be seen as an easy-to-use, inexpensive and natural therapeutic modality to be used within different therapeutic settings.

The aim: Incidents with large number of casualties present a major challenge for the emergency services. Incident witnesses are always the first on scene. Authors aim at giving them an algorithm arranging the widely known first aid rules in such way, that the number of potential fatalities before the services’ arrival may be decreased. Material and methods: The authors’ main aim was creating an algorithm for mass casualty incident action, comprising elements not exceeding first aid skill level. Proceedings have been systematized, which led to creation of mass casualty incident algorithm. The analysis was based on the subject matter literature, legal acts and regulations, statistical data and author’s personal experience. Results: The analysis and synthesis of data from various sources allowed for the creation of Simple Emergency Triage (SET) algorithm. It has been proven – on theoretical level – that introducing an organized way of proceeding in mass casualty incident on the first aid level is justified. Conclusions: The SET algorithm presented in the article is of an implemental character. It may be a supplement to basic first aid skills. Algorithm may also be the starting point for further empirical research aimed at verifying its effectiveness.

The paper presents the issues related to the green economy in the agricultural sector. In order to discuss it, an analysis of the subject literature was carried out and some selected statistical data describing the process of greening of agriculture were presented. The timeframe of the analysis covered the years 2010-2015. The GUS and Eurostat were the source of the used values. Studies have shown that almost all EU countries have increased the area of organic agricultural land in the surveyed period (except for Great Britain). In addition, the article presents the results of pilot studies conducted in the Lodz Region, aimed at diagnosing key barriers to the development of the green economy in rural areas. According to the research, the insufficient level of knowledge of farmers in this area is an important obstacle to building a green economy in rural areas.
