Abstract It is known that oriented strand board (OSB) is prone to water absorption. This characteristic of OSB is undesirable, it can have a negative impact on the physical and mechanical properties of the material and it can also make it prone to attack from wood-destroying insects, rot or mould. The research follows previous work of the authors related to optimisation of surface finishes for OSB in order to increase its moisture resistance. The aim of the research is to compare the rise of dampness in test specimens with different types of coating, spray, primer and waterproofing under predefined conditions. The paper contains a definition of the basic material, test specimens and test methods, and covers 8 different types of surface finish materials selected for application to the test specimens. The results include graphs showing rise of dampness in the test specimens for each day of observation. The results are also discussed and in the conclusion the results are evaluated. The results of the experiments confirm the assumption that the choice of surface finish has a significant effect on slowing down the rise of dampness in OSB.

Purpose Despite recent advances in research on antecedents of social entrepreneurial intentions, founder social identity has rarely been part of the research effort. This paper aims to investigate how different types of founder social identity affect social entrepreneurial intentions (SE intentions). Design/methodology/approach This study investigates how different types of founder social identity, such as Darwinians, Communitarians and Missionaries, affect SE intentions. Specifically, this study predicts that entrepreneurs with Darwinian identity would be less likely to form SE intentions, while those with Missionary and Communitarian identities would be more prone to form SE intentions. The hypotheses are tested on a sample of 725 individuals recruited using Amazon Mechanical Turk. Most of the hypotheses, except for Communitarian identity, are supported by the data analysis. The results contribute to the literature on founder social identity and SE intentions and demonstrate that founder social identity is one of the important antecedents of social entrepreneurial intentions. Findings Two of the hypotheses were supported by the results. Specifically, this study found a positive relation between Missionary founder social identity (its locus of self-definition is “Impersonal-We”) and social entrepreneurial intentions. This research also confirms that Darwinian founder social identity (its locus of self-definition is “I”) has a negative impact on social entrepreneurial intentions. Originality/value First, a person’s social identity has been largely overlooked in social entrepreneurship intention literature (Bacq and Alt, 2018; Hockerts, 2017; Zaremohzzabieh et al, 2019). The findings provide the empirical evidence that individual-level antecedents, especially one’s membership in a social group (i.e. social identity), exert a significant impact on the formation of SE intentions. Second, among the two types of founder social identity predicted to have a positive influence on SE intentions, only Missionary identity was found to have such a positive impact. The typical Communitarian locus of self-definition of “Personal We,” is less influential than the self-definition of the typical Missionary locus of “Impersonal We.” This might imply that not all types of feelings of belonging to a community have a positive impact on the formation and development of social entrepreneurial intentions. Finally, this study found that Darwinians are less likely to pursue social entrepreneurship although the definition of Darwinians is close to the definition of traditional entrepreneurs (e.g. profit/opportunity seekers). This may signify that the traditional concept of entrepreneurship may not be enough to explain different types of entrepreneurial motivations (e.g. social vs commercial entrepreneurship).

The purpose of the article is to reveal the definition of "political provincialism" and to analyze the phenomenon of post-Soviet states in the choice of their values. The article consists of three parts, which reflect the appeal to such concepts as "sovereignty", "political provincialism", "traumatic past" and "resentment", which are actively used in modern political discourse. In the first part, the researcher examines the theoretical aspects of the concept of "sovereignty" in the interaction of different types of states. The author comes to the conclusion that sovereignty continues to be the value that allows the state at any time to realize its inherent functions. The second part of the article reveals the definition of "political provincialism" and analyzes the phenomenon of post-Soviet states. The methods and mechanisms of political provincialism used for self-affirmation and consolidation of new "sovereign communities" in the post-Soviet space are analyzed. The third part is devoted to an examination of the political practices of post-Soviet and post-socialist states in interaction with Russia, the main of which are the traumatic past and resentment. The author notes that the identification of the “Russian” with the discredited “Soviet” allows the current leadership of these countries to form a stable image of the “enemy” among the population, to present Russia as the culprit of all failures. At the same time, in order to receive political and economic preferences from the West, politicians of many states of the post-Soviet space and Eastern Europe are actively using elements of resentment and a traumatic past. All of this ultimately has a very negative impact on the relationship between Russia and Western countries.

The article is devoted to the research of the youth criminal subculture and its impact on the personality of under-aged. In the course of analysis of this negative impact, a definition of the criminal subculture of under-aged was proposed. The main principles of such a criminal subculture as AUE (the acronym, transcribed from Russian: АУЕ or А.У.Е., comes from «Арестантский уклад един» / “Prisoners Unity (Solidarity)” are defined. The reasons contributing to the development of this negative phenomenon and the typical fea- tures of a minor sharing the ideology of the AUE were identified. The methods for counteracting the AUE were proposed. The method- ological basis of the research is formed by general scientific methods: dialectical, system research method, analysis, synthesis, induction, deduction, analogy, etc., as well as such private scientific methods as comparative legal, formal legal, structural and functional, statistical ones. The authors relied on the results of research by Russian and foreign legal scholars, sociologists, psychologists.

Subject. The article examines the laws regulating insider trading. Objectives. The study outlines recommendations for refining Law On Countering the Illegal Use of Insider Information and Market Manipulation and Amendments to Some Legislative Acts of the Russian Federation, № 224-ФЗ of July 27, 2010. Methods. The methodological framework includes a general dialectical method, analysis and synthesis, induction and deductions, and some specific methods, such as comparative and formal logic analysis to specify the definition of insider information, structural logic and functional analysis to improve the mechanism for countering insider trading and market manipulation. Results. We discovered key drawbacks to be addressed so as to improve the business environment in Russia. Although the Russia laws mainly mirror the U.S. laws, they present a more extended list of terms concerning the insider information. I believe the legislative perfection should be continued. Conclusions and Relevance. The study helps apply the findings to outline a new legislative regulation or amend the existing ones, add a new mention on the course of financial markets to students’ books, develop new methods for detecting and countering and improving the existing ones. If all parties to insider relationships use the findings, they will prevent insider trading crimes in financial markets and (or) reduce the negative impact of such crimes on the parties.

Background: Severe asthma is a heterogeneous disease that consists of various phenotypes driven by different pathways. Associated with significant morbidity, an important negative impact on the quality of life of patients, and increased health care costs, severe asthma represents a challenge for the clinician. With the introduction of various antibodies that target type 2 inflammation (T2) pathways, severe asthma therapy is gradually moving to a personalized medicine approach. Objective: The purpose of this review was to emphasize the important role of personalized medicine in adult severe asthma management. Methods: An extensive research was conducted in medical literature data bases by applying terms such as “severe asthma” associated with “structured approach,” “comorbidities,” “biomarkers,” “phenotypes/endotypes,” and “biologic therapies.” Results: The management of severe asthma starts with a structured approach to confirm the diagnosis, assess the adherence to medications and identify confounding factors and comorbidities. The definition of phenotypes or endotypes (phenotypes defined by mechanisms and identified through biomarkers) is an important step toward the use of personalized medicine in asthma. Severe allergic and nonallergic eosinophilic asthma are two defined T2 phenotypes for which there are efficacious targeted biologic therapies currently available. Non-T2 phenotype remains to be characterized, and less efficient target therapy exists. Conclusion: Despite important progress in applying personalized medicine to severe asthma, especially in T2 inflammatory phenotypes, future research is needed to find valid biomarkers predictive for the response to available biologic therapies to develop more effective therapies in non-T2 phenotype.

This article is devoted to the study of the image of Executive authorities in modern Russia. The relevance of the chosen topic of the scientific article is emphasized for the present time, when society and the state are developing methods of countering the coronavirus pandemic – not only in the medical, but, no less important, in the socio-psychological aspect. In this perspective, the consolidating potential of a positive image of government bodies and civil servants is noted. Attention is focused on the terminological apparatus of the problem. Based on the analysis of relevant scientific works, the article provides the author's definition of the image of public authorities. The author notes the peculiarity of the image of Executive authorities, which consists in the presence of two inextricably linked equivalent components – the image of the authority and the image of a civil servant. Image formation of government bodies is considered as a multi-factor interaction of three main subjects: government bodies, the population, and the mass media. The main method of implementation is still the mass communication media, which provide a permanent presence of Executive authorities in the information and communication space. It is noted that the basis for the formation of a positive image of the Executive authority and bureaucracy is their effective functioning. At the same time, the perception of citizens, their attitude to the activities of Executive authorities, the level of trust in them is considered as the main indicator of the modality of the image. Based on the analysis of data from sociological studies, the conclusion about a positive trend in the perception of public authorities and officials by Russians is substantiated. However, there is a negative impact on their image of the lack of these changes and, in General, a low level of openness of public authorities.

The paper purpose is the effectiveness estimation in the technological equipment use, taking into account its reliability and productivity for defective transmission units of buses. The problem consists in the determination of time to be spent on repair of bus transmission units taking into account technological equipment reliability. In the paper there is used a probabilistic method for the prediction bus transmission units, and also a method of the dynamics of averages which allow ensuring minimum of costs for units downtime during repair and equipment cost. The need for repair of transmission units (gear box) arises on an average after 650 hours, the average productivity of the bench makes 4.2 bus / hour. The bench fails on the average after 4600 hours of work, the average time of the bench makes 2 hours. In such a way the solution of the problem specified allows analyzing the necessity of time decrease for transmission unit repair to avoid long downtimes of buses in repair areas without negative impact upon high repair quality and safety during the further operation.

Most historical marine pollution monitoring has proven useless in a management context. A strategy for development of effective marine pollution monitoring programs is outlined. This strategy is based on the following steps: 1) systematic evaluation of the management information needs, 2) identification of the hypothetical impacts associated with those management concerns, and 3) investigation of the feasibility of monitoring those effects such that the existence, or absence, of a specified level of effects can be established in a statistically-valid manner. There are two fundamentally different types of monitoring program: site-specific and regional. These two types of program differ markedly in scope and approach when designed through application of this strategy. The strategy requires development of null hypotheses which address management concerns and which are amenable to scientific testing. In order for the program to be successful, the null hypotheses selected for inclusion in a marine pollution monitoring program must address levels of effect which are predefined to be environmentally significant. The definition of environmentally significant effect levels is a difficult process which must be primarily the responsibility of the managerial community.

Abstract Scholars have long debated whether populism harms or improves the quality of democracy. This article contributes to this debate by focusing on the impact of populist parties in government. In particular, it inquires: (1) whether populists in government are more likely than non-populists to negatively affect the quality of democracies; (2) whether the role of populists in government matters; and (3) which type of populism is expected to negatively affect the quality of liberal-democratic regimes. The results find strong evidence that the role of populists in government affects several qualities of democracy. While robust, the findings related to (2) are less clear-cut than those pertaining to (1). Finally, regardless of their role in government, different types of populism have different impacts on the qualities of democracy. The results show that exclusionary populist parties in government tend to have more of a negative impact than other forms of populism.
