Analytical System

The research was conducted in order to study the breeding value of bulls-producers of various origins, used in the breeding stock of cows of the Yaroslavl breed in the Vologda region. The work was done on the basis of the information analytical system «Seleks» for 52 bulls-producers of Yaroslavl and Holstein breed obtained in different countries of the world and used the herd of 1600 cows dairy cattle breeding farm ZAO Sheksna Vologda region. General scientific research methods were used: monographic, statistical, and data visualization. It was found that the used bulls were produced in 5 countries of the world: the USA, Canada, Germany, the Netherlands and Russia. The vast majority of 76.9% of used manufacturers are of domestic origin. It was determined that in the controlled population, the factor «country of origin of the bull» has a significant influence (P<0.001) on the breeding value of producers based on the maternal ancestry (η2=0.46). Bulls from Canada and the United States have the highest indicators of breeding value for the milk yield of their maternal ancestors — 15436 and 14210 kg of milk, respectively. Domestic bulls have a breeding value of 8310 kg of milk, which is 7126 kg less than that of producers from Canada (P ≤ 0.001). The best indicators of bull potential realization by maternal ancestry were found in the daughters of Dutch and Russian producers (64.1% and 69.5%, respectively). The higher-than-average yield for the herd is obtained from cows with a Holstein blood type of 50% or more, using purebred Holstein bulls, both foreign and domestic selection, as well as Yaroslavl bulls with a high degree of blood type for improving breed (75-88%). In order to preserve the Yaroslavl breed of cattle, it is necessary to determine the optimal degree of blood transfusion of the Holstein breed, taking into account not only the productive characteristics, but also the characteristics of the health and longevity of animals.

Sandra Ramos (b. 1969) is one of the few artists to reflect critically on both sides of the Cuban di-lemma, fully embodying the etymological origins of the word in ancient Greek: di-, meaning twice, and lemma, denoting a form of argument involving a choice between equally unfavorable alternatives. Throughout her works she shines a light on the dilemmas faced by Cubans whether in Cuba or the United States, underlining the bad personal and political choices people face in both countries. During the hard 1990s, while still in Havana, the artist focused on the traumatic one-way journey into exile by thousands, as well as the experience of profound abandonment experienced by those who were left behind on the island. Today she lives in Miami and operates a studio there as well as one in Havana. Her initial disorientation in the USA has morphed into an acerbic representation and critique of the current administration and a deep concern with the environmental collapse we face. A buffoonlike Trumpito has joined el Bobo de Abela and Liborio in her gallery of comic characters derived from the rich Cuban graphic arts tradition where she was formed. While Cuba is now represented as a rotten cake with menacing flies hovering over it ready to pounce, a bombastic Trumpito marches across the world stage, trampling everything underfoot, a dollar sign for a face.

The Republic

According to the current “Instruction” used in dairy cattle selection and breeding in the Republic of Kazakhstan, bulls-producers of dairy breeds are assessed according to the their offspring quality based on the principle of “peer daughter”. This means that the phenotypic indicators of the daughters of the tested bulls are compared with the corresponding indicators of their peers. In European countries with developed dairy cattle breeding, as well as in Canada, the USA, etc., to ensure a reliable forecast of the genetic value of individuals (primarily, bulls-producers), use is made of the best linear unbiased forecast method (BLUP method). This method implies that the breeding value of producers is determined by the deviation values of the development of traits of the examined animal from its average values in the population. Especially urgent area is the research aimed at improving breeding programs, including assessing the breeding value of bulls-producers of dairy breeds using BLUP methods based on the productive qualities of the mass of dairy cattle in the Republic of Kazakhstan. The research material included the data on the phenotypic indicators of the milk productivity of first-calf cows (the amount of milk yield, the content of fat and protein in milk, the yield of milk fat and protein) of the Holstein black-motley dairy cattle breed, obtained from the information and analytical database of the Republic of Kazakhstan for 2016–2017. It was found that when evaluating according to the official “Instruction”, 16 sires out of 256 bulls (6.2%) got the stud category in 2016, 14 sires (9.2%) out of 152 bulls in 2017, and – 30 sires of 249 bulls (12.0%) over the cumulative period. The results of the conducted research prove that the use of the classic “Instructions” in dairy cattle breeding has lower efficiency (by 42.8–90.0%) as compared with the assessment of the breeding value of bulls based on the BLUP method.The selection of sire bulls into breeding groups based on the “peer daughter” methodology is not reliable enough and rather ineffective. Comparing the results of assessing the breeding qualities of sire bulls, obtianed using two methods in all compared periods (2016, 2017, 2016–2017), the authors established a clear superiority of the BLUP method over the current Instruction used in the Republic of Kazakhstan.

Проведен сопоставительный анализ генеалогической структуры племенного поголовья ярославской породы Вологодской области по данным 2005 и 2018 годов. Установлено, что в 2005 году в структуру породы входили 8 отечественных генеалогических линий. В результате скрещивания с голштинской породой произошли значительные изменения. Доля животных, принадлежащих к линиям ярославской породы, уменьшилась со 100% в 2005 году до 35,3% в 2018 году. В генеалогическую структуру современной популяции добавились 3 линии голштинской селекции, к которым на 1.01.2019 года относится большая часть маточного поголовья: к линии Рефлекшн Соверинга 198998 — 42,9%, Вис Бэк Айдиала 1013415 — 13%, Монтвик Чифтейна 95679 — 8,8%. Скрещивание с голштинской породой оказало положительное влияние на повышение молочной продуктивности животных ярославской породы. Средний надой на 1 корову увеличился на 1670 кг молока, доля коров с продуктивностью более 6000 кг молока выросла на 35%. В результате расчета корреляционной зависимости между кровностью по голштинской породе и массовой долей жира и белка в молоке установлено, что скрещивание не ухудшило качественные показатели молока коров ярославской породы (степень кровности с МДЖ — r=-0,01; с МДБ — r=0,09; P<0,01), но в то же время отразилось отрицательно на продолжительности хозяйственного использования животных в стаде (r=-0,27; P<0,001). Для дальнейшего совершенствования породы следует определить оптимальную степень прилития крови голштинской породы. А с целью сохранения генофонда необходимо получение нового поколения чистопородных быков ярославской породы с более высоким потенциалом продуктивности. The authors conduct a comparative analysis of the genealogical structure of the breeding stock of the Yaroslavl breed in the Vologda region on the basis of the data for 2005 and 2018. It is established that in 2005 the structure of the breed included 8 domestic genealogical lines. As a result of the crossing with the Holstein breed, significant changes occurred. The share of animals of the Yaroslavl breed lines decreased from 100% in 2005 to 35.3% in 2018. The genealogical structure of the modern population got 3 added lines of the Holstein selection which as of 1.01.2019 include most of the breeding stock: Reflection Sovering line 198998 - 42.9%, Vis Back Ideal line 1013415 - 13%, and Montwick Chieftain line 95679 - 8.8%. The crossing with the Holstein breed had a positive effect on the increase in the milk productivity of the Yaroslavl breed animals. The average milk yield per 1 cow increased by 1670 kg of milk and the share of cows with the productivity of more than 6000 kg of milk increased by 35%. The results of the calculations of the correlation between the Holstein thoroughbredness and the fat and protein content in the milk showed that the crossing did not impair the quality indicators of the milk the Yaroslavl breed cows (thoroughbredness degree with the fat content r=-0.01; with the protein content r=0.09 P<0.01), but at the same time had a negative impact on the duration of the economic use of the animals in the herd (r=-0.27; P<0.001). For further improvement of the breed, there is a need to determine the optimal degree of crossing with the Holstein breed. Also, in order to preserve the gene pool, there is a need to obtain a new generation of purebred bulls of the Yaroslavl breed with a higher productivity potential.

COVID-19 is a serious coronavirus disease that is spreading all over the world. As of the date of this publication, 2.834.134 people have been infected with COVID-19 and 197.924 deaths have been recorded in 185 countries (John Hopkins Corona Resource Center, 25th April 2020) [1]. This overwhelming mortality rate requires intensive research activities around the world. To date, the number of deaths per day in the United States is still killing, indicating an uncontrollable state of infection spread. SARS-CoV-2 binds to the angiotensin II receptor in various tissues of the human body, particularly in the oral cavity and tongue. SARS-CoV-2 requires the cheerful TMPRSS2 to activate this inertia. SARS-CoV-2 uses the ACE2 receptor as a gateway to the lungs. The SARS-CoV-2 virus binds with the spike protein to the ACE2 receptor. COVID-19 is more common among African Americans in the USA (Science 10th April 2020). The comfort and the emotional loading capacity of the employees in the health service are key components for the maintenance of the essential health services during the outbreak of the COVID-19 virus (Coronavirus) [2,3]. Hence, it will be important to anticipate the charges linked with this work and to release support for employees in the health service. The supervision and assessment of the psychic health and the well-being of the employees in the health service will be important, just as the efforts to guarantee a successful reunion with colleagues if they are infected.

The paper examines the interests of Russia, the United States and China in the regions of the world and identifies the priorities of Russia's activities in Europe, Central Asia and the Caucasus, the Asia-Pacific region, the Arctic, Africa, the Middle East and Latin America, their comparative assessment with the interests of the United States and China. An approach to assessing the impact of possible consequences of the activities of the United States and China on the realization of Russia's interests is proposed. This makes it possible to identify the priorities of the policy of the Russian Federation in various regions of the world. The results of the analysis can be used to substantiate recommendations to the military-political leadership of our country. It is concluded that the discrepancy between the interests of the United States and China is important for the implementation of the current economic and military policy of the Russian Federation.

The Impact

Every few decades, the world order changes due to various geopolitical, economic and other circumstances. For example, as a result of globalization, the world order has undergone significant changes in the last forty years. Globalization has led to the destruction of the postwar world order, as well as to world leadership by the United States and the West. However, in recent decades, as a result of globalization, the U.S. and the West began to cede their leadership to developing countries, so there is now a change in the economic structure of relations in the world system. Today the center of economic growth is in the East, namely in Asia. There are no new superpowers in the world at the moment, but the unipolar world will cease to exist due to the weakening of the U. S. leadership, which will lead to a change in the world order. A new leader, which may replace the U. S., will not have as wide range of advantages as the USA has. Most likely, the essence of the new order will be to unite the largest countries and alliances into blocks, for example, the USA together with the Trans-Pacific Partnership, the EU, etc. The article outlines forecasts of GDP growth rates as well as the global energy outlook; analyzes the LNG market as well as the impact of the pandemic on the global oil and gas market; and lists the characteristics of U. S. geopolitics.

Exploratory Data

This article presents the first results of a statistical analysis of the ownership links between the major European and American defence contractors. This approach, centred on the shareholders and subsidiaries of these companies, enables us to explore the depth of the national links (company and country of origin) and the density of the ownership cooperation that exists within Europe, as well as with the rest of the world, particularly the United States. Information about defence contractors’ ownership links is difficult to obtain and precautions must be taken in the interpretation of the results.  In terms of defence contractor shareholders, it would appear first that the national link is strong for Sweden, Spain and France, less so for Germany and Italy, and particularly weak for the United Kingdom. Next, in European terms the links are concentrated on Airbus, MBDA and KNDS and are little developed in other companies. Finally, we observe asymmetrical links with the USA and a significant presence of American investment funds.

The Moment

Building own business is a long-term and laborious process. A person who leads a startup tries to start with building own business by taking first steps toward financial independence. Analyzing conditions in Poland, on average every second startup sells its services abroad, admittedly it is good news, although half of them do not export at all. Half of the startups which export their services and goods generates more than 50% of their revenues outside Poland. Very interesting is the fact that 60% of exporters have conducted their foreign sale since the moment of establishing their business. On which markets do they sell their services? It turns out that the most popular are markets in the European Union (54%), including the United Kingdom 14% and Germany 9%. Only about 25% of Polish startups exports their products and services to the United States. Taking the United States into consideration, in 2008 the USA lost their leading position in the number of startups which are newly created and achieving success in business. Currently in terms of the number of new startups the USA is on a quite distant place after Denmark, Finland, Sweden, Hungary, New Zealand, Israel or Italy. In short, more companies were closed than created, so it was, as a matter of fact, like in Poland. Therefore, the condition to improve the development of startups both from Poland and other countries all the world is to increase cooperation and coopetition.

European direct investment in Brazil dates back to the discovery of the country and has been since then either hegemonic or more important than a superficial observation can grasp, as this work aims at showing. During the 20th century, the United States has replaced Britain as the worlds economic superpower and the largest direct investor. US dominance in the world economy and geographical proximity to Brazil would suggest that US investments were by far the largest in the country during that century. Furthermore, as Japan had become the second largest economy in the world in the 1980s, we would expect that this would be reflected in the data of the largest multinationals in Brazil. However, as our investigation suggests, Western European direct investment has been as large (and in many occasions even larger) as that of the USA and Japanese firms have never had a prominent presence among the largest firms in Brazil, at least until the late 1990s.

Abstract Background Understanding the impact of the burden of COVID-19 is key to successfully navigating the COVID-19 pandemic. As part of a larger investigation on COVID-19 mortality impact, this study aims to estimate the Potential Years of Life Lost (PYLL) in 17 countries and territories across the world (Australia, Brazil, Cape Verde, Colombia, Cyprus, France, Georgia, Israel, Kazakhstan, Peru, Norway, England & Wales, Scotland, Slovenia, Sweden, Ukraine, and the United States [USA]). Methods Age- and sex-specific COVID-19 death numbers from primary national sources were collected by an international research consortium. The study period was established based on the availability of data from the inception of the pandemic to the end of August 2020. The PYLL for each country were computed using 80 years as the maximum life expectancy. Results As of August 2020, 442,677 (range: 18–185,083) deaths attributed to COVID-19 were recorded in 17 countries which translated to 4,210,654 (range: 112–1,554,225) PYLL. The average PYLL per death was 8.7 years, with substantial variation ranging from 2.7 years in Australia to 19.3 PYLL in Ukraine. North and South American countries as well as England & Wales, Scotland and Sweden experienced the highest PYLL per 100,000 population; whereas Australia, Slovenia and Georgia experienced the lowest. Overall, males experienced higher PYLL rate and higher PYLL per death than females. In most countries, most of the PYLL were observed for people aged over 60 or 65 years, irrespective of sex. Yet, Brazil, Cape Verde, Colombia, Israel, Peru, Scotland, Ukraine, and the USA concentrated most PYLL in younger age groups. Conclusions Our results highlight the role of PYLL as a tool to understand the impact of COVID-19 on demographic groups within and across countries, guiding preventive measures to protect these groups under the ongoing pandemic. Continuous monitoring of PYLL is therefore needed to better understand the burden of COVID-19 in terms of premature mortality.
