КЛАНОВЫЙ АСПЕКТ ПИРАТСКОЙ ПРОБЛЕМЫ СОМАЛИ

This research paper investigates issue of infl uence clan relationships for piracy development on the Horn of Africa. Author contemplates that presence of stable internal links in Somali impedes possible external solution of the piracy problem. Therefore, the identifi cation structural interrelationships within the Somali society could be important both for understanding of the political and socio-economic situation in the region and also it will promote full understanding of internal reasons of piracy problem on the Horn of Africa.Настоящая статья посвящена вопросу о влиянии клановых отношений на развитие пиратства в регионе Африканского Рога. Автор полагает, что наличие устойчивых клановых связей внутри Сомали препятствует возможному внешнему, международному, решению проблемы пиратства. Следовательно, выявление структурных взаимосвязей внутри сомалийского общества может оказаться важным для понимания политической и социально-экономической ситуации на данной территории, а также будет способствовать более полному пониманию внутренних причин международной проблемы пиратства на Африканском Роге

The phonon Hall effect: theory and application

We present a systematic theory of the phonon Hall effect in a ballistic crystal lattice system, and apply it on the kagome lattice which is ubiquitous in various real materials. By proposing a proper second quantization for the non-Hermite Hamiltonian in the polarization-vector space, we obtain a new heat current density operator with two separate contributions: the normal velocity responsible for the longitudinal phonon transport, and the anomalous velocity manifesting itself as the Hall effect of transverse phonon transport. As exemplified in kagome lattices, our theory predicts that the direction of Hall conductivity at low magnetic field can be reversed by tuning temperatures, which we hope can be verified by experiments in the future. Three phonon-Hall-conductivity singularities induced by phonon-band-topology change are discovered as well, which correspond to the degeneracies at three different symmetric center points, \Gamma, K, X, in the wave-vector space of the kagome lattice.Comment: 19 pages, 6 figure

Competencies diversification in COVID-19 pandemic conditions (case of congress-exhibition service market)

The article considers the contemporary state of congress-exhibition service market as critical. Organizing the major events which have non-negligible impact on economical, innovative, technological, investment processes has been limited due to the new coronavirus infection (COVID-19). Decision-making process of putting limitation on activities organization has been derived from external environment adverse events aligned with current sanitary-epidemiological situation. There has been analyzed the potential loss due to cancelling or rescheduling congress-exhibition events in 2020. Demand and supply reduction necessitate searching alternative development directions and core business diversification. In the capacity one of potential and perspective directions There was stated a social activity vector of Roscongress foundation as a non-financial development institution and organization of Saint-Petersburg International Economic Forum, and Expoforum International, Ltd. as operator of holding forum venue. Saint-Petersburg International Economic Forum has endowed with not only economic impact but also influence on forming-up communications intended to favor realization of the social programs during offline traditional holding event. There have been analyzed the quantitative indicators dynamics of St.-Petersburg International Economic Forum and qualitative indicators in the context of thematic zones of social orientation, which gives the ground to state the wide institutional influence on social economic processes in tourism destination and in other fields. Cooperation programs diversification with local communities has been allowing positive image creation as one of elements of destination strategic promotion on the world congress and tourist map

Institutionalization of Exhibition and Convention Activity in Innovation-Based Economy

The meaning of exhibition and convention activity is currently undergoing serious changes. Contemporary forums and exhibitions promote goods and services, as well as create new social, economic, and political relation standards. The contemporary crisis has revealed some regulatory gaps. However, innovative marketing approach to exhibition and convention events can help industry to recover and grow. Exhibition and convention events produce not only economics effects: they also promote institutional, public, and innovative development. The present research featured cooperation and coordination of stakeholders in exhibition and convention activities, as well as related legal, marketing, and theoretical factors. The research objective was to develop the economy of events – a new methodological approach to assessment of non-material effects of exhibition and convention activity. The research was based on the methods of institutional economics; the paper offers an analysis of existing legal frameworks and standards. The author believes that exhibition and convention sphere needs institutional background based on the interaction of existing norms and methods within event system. This theoretical aspect made it possible to consider the role of events in the context of building sustainable interrelationships between institutes and society, as well as to reinterpret the role of exhibition and convention activity in the modern agenda
