ELABORATION OF AN OPTIMAL MODEL FOR THE DEVELOPMENT OF GASTRONOMIC TOURISM IN THE RIGHT-BANK POLISSIA OF UKRAINE

Based on the study of spatial forms of tourism organization, their structure and patterns of formation to prove that the most optimal form is a cluster model of organization. Also to describe the features, structure, composition and life cycle of potential tourist clusters of the object of study. In the process of substantiating the development of a cluster model on the Right-Bank Polissia of Ukraine the authors used a combination of general and special methods of scientific research (modeling, information, cluster analysis, geoinformation mapping). It is proved that the creation of regional clusters of gastronomic tourism development of the Right-Bank Polissia of Ukraine will lead to the strengthening of competitive advantages of its participants. The proposed cluster model has been visualized cartographically, also its administrative and functional structure has been developed. Substantiated clusters of gastronomic tourism of the region will become the basis for further scientific research aimed at dividing the territory of the Right-Bank Polissia of Ukraine on the basis of the operational units allocation for gastronomic and tourist zoning.

Directed motivational currents: A systematic review

Directed motivational currents, unique and intense goal-directed motivational surges lasting over a period of time, have received increasing attention recently. This article reports the first systematic review of this phenomenon. A total of 21 reports appearing between 2013 and 2020 were included in the analysis. The results show that the majority of empirical reports were small-scale qualitative studies (median = 18 participants). The evidence on the three characteristics proposed as necessary and/or distinguishing conditions of directed motivational currents (vision, salient facilitative structure, and positive affect) is inconclusive due to the presence of directed motivational currents cases not exhibiting these features, and the absence of direct comparative analyses with non-directed motivational currents cases. A few intervention studies (N = 4) were conducted, but their results are also inconclusive due to a number of methodological limitations. Contrary to the claim that directed motivational current experiences are the “optimal form” of motivation, the results additionally showed that these experiences could lead to intense stress, anxiety, depression, sleeplessness, and panic attacks, thereby raising ethical concerns about deliberately inducing directed motivational currents in learners. We conclude that, although the concept of directed motivational currents is promising, more research is needed to reach a better understanding of its potential. We end this article by suggesting directions for future research into directed motivational currents, including renaming them as sustained flow.

Series expansion of Leray–Trudinger inequality

In this paper, we establish an infinite series expansion of Leray–Trudinger inequality, which is closely related with Hardy inequality and Moser Trudinger inequality. Our result extends early results obtained by Mallick and Tintarev [A. Mallick and C. Tintarev. An improved Leray-Trudinger inequality. Commun. Contemp. Math. 20 (2018), 17501034. OP 21] to the case with many logs. It should be pointed out that our result is about series expansion of Hardy inequality under the case $p=n$ , which case is not considered by Gkikas and Psaradakis in [K. T. Gkikas and G. Psaradakis. Optimal non-homogeneous improvements for the series expansion of Hardy's inequality. Commun. Contemp. Math. doi:10.1142/S0219199721500310]. However, we can't obtain the optimal form by our method.

The Optimal Reinsurance Strategy under Conditional Tail Expectation (CTE) and Wang’s Premium Principle

In this study, we take the conditional tail expectation (CTE) as the constraint condition and consider the optimal reinsurance issues under Wang’s premium principle in general insurance contracts. With the confidence level and the distortion function in Wang’s premium principle given by the insurer in advance, a threshold can be obtained. When the insurer’s risk tolerance level is greater than this value, the optimal reinsurance is a proportional reinsurance in which the deductible equals to this value, else the optimal form of reinsurance is a stop-loss reinsurance. Corresponding numerical examples and economic explanations are also given.

Endodontic Applications of 3 D Printing

3D Printing is a method of additive production supply that includes computing layer next layer to optimal form a target. It is helpful in managed endodontic and accurate cavity preparations. Also, can be practiced for dental pulp recovery by following pulp tissue. Since 3D printing is dependent in an additive manner, it reduces wastage that is usually connected with subtractive methods identified as milling. It performs for significant time conserving as well as is one of the largest free digital media. Moreover, it can be readily used in various situations proceeding for easy applicability as well as versatility to produce multiple images.

Mechanism of public-private partnership as a way to support sustainable development of rural territories

In the article, the authors have raised an urgent topic related to the provision of state support for rural areas. Attention is focused on the deficit of most of the budgets of both the municipal and regional levels, which does not contribute to the development of the infrastructure of the territories. In addition, the low investment attractiveness does not allow relying on private capital. The authors are confident in the rationality of the development of public-private partnership, as the most optimal form of relationship between private capital and public authorities.

Current management strategies for osteochondral lesions of the talus

The management of symptomatic osteochondral lesions of the talus (OLTs) can be challenging. The number of ways of treating these lesions has increased considerably during the last decade, with published studies often providing conflicting, low-level evidence. This paper aims to present an up-to-date concise overview of the best evidence for the surgical treatment of OLTs. Management options are reviewed based on the size of the lesion and include bone marrow stimulation, bone grafting options, drilling techniques, biological preparations, and resurfacing. Although many of these techniques have shown promising results, there remains little high level evidence, and further large scale prospective studies and systematic reviews will be required to identify the optimal form of treatment for these lesions.

Turbulence, Firm Decentralization, and Growth in Bad Times

What is the optimal form of firm organization during “bad times”? The greater turbulence following macro shocks may benefit decentralized firms because the value of local information increases (the “localist” view). On the other hand, the need to make tough decisions may favor centralized firms (the “centralist” view). Using two large micro datasets on decentralization in firms in ten OECD countries (WMS) and US establishments (MOPS administrative data), we find that firms that delegated more power from the central headquarters to local plant managers prior to the Great Recession outperformed their centralized counterparts in sectors that were hardest hit by the subsequent crisis (as measured by export growth and product durability). Results based on measures of turbulence based on product churn and stock market volatility provide further support to the localist view. This conclusion is robust to alternative explanations such as managerial fears of bankruptcy and changing coordination costs. Although decentralization will be suboptimal in many environments, it does appear to be beneficial for the average firm during bad times. (JEL D22, G12, G32, G34, L23)

Axiological role of emotionality

The paper explores the specificity of emotional processes, within total mental dynamics of personality. It is explained that they have both subjective and objective dimension, that they concern the selection of individual attentional priorities, but also seeing the objective order of values. The characteristics of emotional evaluation are considered and the optimal form of human emotions is examined. Incorrect and correct emotions are differentiated, whereby formal meaning of super-subjective correctness, that is, the value dignity of man?s emotionality is explained. Certain relevant aspects of axiological understanding of emotions at Max Scheler and Ronald de Sousa are compared. Finally, the author presents arguments in favor of his own thesis that the objective dignity of not only individual emotions, but also the total emotional life of personality is attainable.
