Currently, dry mixes (CDM) play an important role in the development of the world market of building materials. The industry of construction and finishing materials in Russia is quite young: the first time the dry building mixes appeared on the Russian market in the late 1980s, the consumption structure of CDM in the domestic market the main share (70%) are in the adhesive and plasters. The use of other compositions, in particular mixtures for self – leveling floors, does not have significant volumes and often the reason for this is the lack of design solutions and the low level of qualification of specialists at different levels from workers to designers who do not own CDM technologies.

Cooperative principles represent one of the three elements of cooperative identity. In their current form, they have existed since 1995, when they were adopted by the International Cooperative Alliance, and they represent a recommendation to cooperatives around the world on how to organize their business. Adherence to these recommendations in everyday business practice of cooperatives is extremely challenging. In fact, there is a consensus in the literature that deviation from cooperative principles is inevitable. The paper analyzes the experiences of the Republic of Serbia in the implementation of cooperative principles from time of the first cooperatives until today, with special emphasis on agricultural cooperatives. The aim of this paper is to examine the extent to which cooperative principles are respected in the business of cooperatives in Serbia, what factors led to deviations from these recommendations and what consequences this had on the success of these organizations. The paper presents a synergy of theoretical consideration of the problem and examination of experiences of agricultural cooperatives in Serbia in the implementation of cooperative principles. Conducted research indicate that during the development of cooperatives, different levels of deviations from cooperative principles in the practice of agricultural cooperatives were recorded, from very mild to extremely significant deviations that led to the suppression of true cooperative nature. Modern cooperative practice in Serbia is marked by a low level of knowledge of the elements of cooperative identity by the members and management of cooperatives, which further stipulates the posibility of their implementation in practice.

This study investigates and compares oilseeds price volatilities in the world market and the Ethiopian market. It uses a monthly time series data on oilseeds from February 1999 to December 2012; and analyses price volatilities using unconditional method (standard deviation) and conditional method (GARCH). The results indicate that oilseeds prices are more volatile, but not persistent, in the domestic market than the world market. The magnitude of the influence of the news about past volatility (innovations) is higher in the domestic market for Rapeseed and in the World market for Linseed. However, in both markets there is a problem of volatility clustering. The study also identified that due to the financial crisis the world market price volatilities surpassed and/or paralleled the higher domestic oilseeds price volatilities. The higher domestic oilseeds price volatility may imply that the price risks are high in the domestic oilseeds market. As extreme price volatility influences farmers` production decision, they may opt to other less risky, low-value and less profitable crop varieties. The implications of such retreat is that it may keep the farmers in the traditional farming and impede their transformation to the high value crops, and results in lower income hindering the poverty reduction efforts of the government. This is more important to consider today than was before, because measures undertaken to reduce poverty must bring sustainable change in the lives of the rural poor. For this reason, agricultural policies that enable farmers cope with price risks and enhance their productivity are crucial.

The world experience of implementation of import substitution strategy is being studied; reveals the essence of the main models; Identify those aspects that will prove useful in modern Russian conditions. The development of import-substituting industries according to the intra-oriented strategy is carried out in order to develop exclusively the domestic market of the country. From the point of view of the national economy, this strategy leads to the preservation of the backlog, primarily in the field of technological and scientific-technical cooperation and prevents the emergence of industries in the economy-locomotives that can ensure the world level of progress. The use of this model of import substitution has become a determining trend in the development of the so-called new industrial countries (NIS).The intra-oriented strategy of import substitution plays a stimulating role in creating a diversified national economy, expanding the production of important goods on its own. The conceptual basis for the implementation of this strategy was the theory of the peripheral economy, developed by a group of Latin American scientists headed by the Executive Secretary of the UN Economic Commission. According to this concept, the demand for products. The use of the designated model of import substitution has become a trend of development of the so-called new industrial countries of Latin America. Another option for the implementation of import substitution policy can be a strategy of foreign-oriented import substitution, which is characterized by the achievement of structural changes in the economy through the replacement of imported components and parts in export products. Implementation of import-substituting policy, according to this model, involves the development of production of national goods on a sufficiently large domestic market, followed by their promotion on the world market.

In the course of the last decades of the twentieth century, more than 30 new diseases were determined for the first time in history. Bovine spongiform encephalopathy (BSE), or "mad cow disease" is one of them. The disease implies the subacute neurodegenerative transmission of spongiform encephalopathy and it was diagnosed and described for the first time in Great Britain in 1986. A theory has been established that BSE is spread through feedstuffs, more precisely, meat-bone flour which contains infective proteins of ruminants, and legislature has been passed throughout the world with the objective of preventing the entry of meat-bone flour into the food chain. The complete ban of the use of meat-bone flour for all farm animals (with the exception of fish flour for non-ruminants) and an adequate thermal treatment in the production of meat-bone flour (133?C, 3 bar, 20 min) are the elements on which the European Union (EU) legislature is based. The regulations in our country include a ban on the use of meat-bone flour in cattle feedstuffs and a ban on imports of beef proteins. The implementation of this legislature throughout the world requires the corresponding analytical means. At the present time, there are several available possibilities: optic microscopy, PCR, immunoprobes, spectroscopic methods, and several others which are still being examined for use for this purpose. All the analytical methods are being applied with the objective of controlling the implementation of the current regulations, but also in order to discover possible cross contamination that could take place in factories of animal feedstuffs, during transportation, storage, or on farms, in particular when there are no separate lines for feedstuffs that contains meat-bone flour and others in which even its traces are banned. In order to secure the successful control and prevention of bovine spongiform encephalopathy in our country, as well as to secure the unhindered continuation of the integration processes with the European Union, it is necessary to create an adequate system for the monitoring of this disease, not only because of food safety as a precondition for the good health of people, but also for commercial reasons, as that is the only way to have an active role on the world market. .

It was at the 2016 Rio Olympic Games that, for the first time, activists mobilised against the Israeli securitisation of sport. Brazilian-Palestinian solidarity action, calling for Rio to be an ‘Olympics without Apartheid’, led the then Brazilian government to distance itself from a $2 billion agreement with an Israeli security company. The authors discuss the way in which the solidarity movement emerged and how Israeli companies use Gaza as a ‘lab’ to develop weapons, policing techniques and security technologies for sale on the world market. They point to the parallels between Israel’s securocratic war of pacification and Brazil’s immense security measures against the favelas during a decade of sport mega-events. They trace the flow of securitisation between Israel and Brazil in terms of racial apartheid and settler colonialism to show the impacts on people in occupied Palestine and the favelas of Rio.

Import substitution is a process of gradual displacement of foreign goods in the domestic market by analogues of domestic production. In Russia, the need to accelerate the development of national production of agricultural raw materials and food products has been discussed since the beginning of the second decade of this century, since the increasing share of foreign goods in the national consumption of products on the domestic market has become a signal of a violation of the country’s food security indicators. The State authorities made the appropriate necessary decisions, which were implemented. This issue became particularly relevant after 2014, when Russia suddenly faced sanctions against it from the United States and its NATO allies. This led to the adoption of the counter-embargo, stimulated the development and implementation of additional eff orts to develop import substitution in our country. In a fairly short period of time, our country has achieved very signifi cant results in increasing its independence from imports, primarily in the food market, in particular in eliminating the shortage of meat and dairy products. The domestic market has become fully secured due to the national production of poultry, pork, many types of vegetables, and confectionery. The national production of beef and dairy products has expanded. This made it possible to signifi cantly reduce the import supply of such goods. The authors consider and analyze the current trends and features of this process. For a number of food products, Russia has become a major exporter on the world market, capturing major positions in the world market of wheat, sunflower oil, fats, a number of other food products, as well as fertilizers. The demand for Russian food products on a large scale is presented by China, the countries of the Middle East, and North Africa. Nevertheless, there are still unresolved problems in the country, which the authors point out. In particular, it is necessary to make eff orts to reduce import supplies of seeds, seedlings, breeding cattle, highly specialized agricultural machines, food equipment, to expand the development or purchase of technologies for processing agricultural products, the production of food additives and other imported components for the processing industry. Of course, there will remain some types of tropical agriculture, which the country will continue to import, since it is impractical to develop their production in Russia for climatic reasons.

The article traces the role of the Ural-Siberian region in Russia’s responses to historical challenges in the era of modernization. It is concluded that this role has been steadily increasing over the course of four centuries — from traditional society to the end of the historical period of modernization. Such a chronologically large and meaningfully diverse process is revealed for the first time in historiography. Addressing it made it possible to assess the strategy of a particular region in ensuring the country’s responses to world challenges at the expense of its own resources. Historical experience has shown that the region stayed in history as a reserve territory of the deep rear. These tendencies are traced on the materials of the procurement of furs, extraction of silver and gold, and ferrous metallurgy products. These resources contributed to Russia’s entry into the world market, the formation of its military-industrial complex, and responses to the challenges of the times and global competitors. The exploitation of such wealth controversially influenced the modernization processes and overcoming the country’s lag behind the advanced states of the world, although imperial Russia sometimes outstripped its opponents in some indicators, in particular, in the production of ferrous metals. Each of the five macro problems posed in this text requires further elaboration precisely from the standpoint of challenges. It is necessary to continue studying the perception of these problems in our country and the ways of organizing responses to them, as well as the reaction of the world community to Russia’s responses. This is the task for specialists in both Russian and general history.

Abstract Smoking epidemics have increased the number of smokers around the globe. Moreover, the world urbanization steadily increases. As a result, environmental problems are exacerbated by the proliferation of combustible and electronic cigarettes and the cement invasion of permeable spaces. Therefore, sustainable construction/building materials that use recycled ingredients like cigarette filters are worth considering. This paper assesses and compares, for the first time in the literature, the chemical and mechanical properties of geopolymer concrete substituted by 0, 10, 15, and 20% by weight of cigarette filters. Results have shown that the higher the amount of cigarette filters, the lower the mechanical strength. However, the results also indicate that the geopolymerization reaction is still in progress as the compressive strength of all aged samples is still increasing.
