The energy market is gradually changing from centralized trading to peer-to-peer trading due to the tremendous increase in a microgrid with green energy resources. When more generating units are included in the microgrid, the possibilities of more reactive power flows exist in the system that leads to high transmission loss which has to be optimized. The reactive power is one of the essential ancillary services in the microgrid towards preserving the voltage in the transmission and distribution line. The major contribution of the paper is towards managing the ancillary service in the distributed energy network economically and technically. This study aims to estimate and optimize the power loss, reactive power, and price management as well. Towards optimization, the self-balanced differential evolution algorithm (SBDE) is used in this study. A distribution system operator is involved in coordinating the sellers and buyers. The proposed layered microgrid architecture uses the blockchain technology for reactive power price management by providing transparency and security among peers. The process of converging various transactions into a block and adding in the distributed blockchain is illustrated. Multiple transactions are performed by using the proposed methodology, giving efficient energy transaction. The results show that the power loss is minimized using SBDE algorithm for different cases. Additionally, the study has demonstrated the price allocation of the optimal reactive power obtained from providers. The blockchain technology embedded in reactive power pricing will play a significant role in the evolution of traditional power distribution systems to active distribution networks.

Currently, almost every business entity has one or more social media accounts. This statement is true for companies operating in creative areas as well. Social media make it possible to perform widely understood marketing-oriented undertakings. They allow for toll-free presentation of a particular company, its history, products, achievements, as well as for encouraging prospective customers to visit its websites. Social media marketing plays an important role in the satisfactory advertising of creative brands, companies, and products. The aim of this article is to discuss the possibilities of utilizing social media marketing by a creative company dealing with the production of computer games. The authors have attempted to analyze selected elements of computer game promotion opted for by the CD Projekt Capital Group. As of currently, The Witcher game is a product that is well known and highly appreciated all over the world. Nevertheless, its promotion has required the utilization of a proper marketing strategy, based on social media-specific tools.

In a turbulent environment, companies face disruptive events and must build organisational resilience in order to thrive. This unique book offers new, cutting-edge research on how trust can build and develop resilience. The authors combine theoretical and empirical perspectives on the two issues of trust and organisational resilience in an environment that is difficult to predict. The authors firstly discuss the challenges the turbulent environment poses before exploring the influence of trust and providing practical case studies on topics such as brand trust, dynamic capabilities and business models. Examples are drawn from high-growth enterprises demonstrating first-hand how organisations that develop trust have survived turbulent conditions. This novel book is the first to combine the two disciplines of trust and resilience and will be a valuable reference for researchers and upper level students of strategic management and crisis management in particular. <!----> <!----> <!----> <!---->

This paper aims to evaluate the response of high-growth enterprises (HGEs) to the circumstances caused by the COVID-19 pandemic. Adaptation to the pandemic situation presented an enormous challenge for these enterprises. The ability to exercise sound judgment affects rational decision-making and adaptation to the circumstances. The study adopts a situational theory perspective related to high-growth enterprises. Data collection was conducted twice - at the beginning of 2019, and after the third wave of the COVID-19 pandemic, in October 2021. The Generalized Estimating Equations (GEE) method was used to analyze the sample of 150 Polish HGEs. Results show that the impact of the pandemic mainly relates to the reduction or stagnation of market opportunities. The importance of human resources decreased in favor of technological and financial resources. The majority of the surveyed companies also maintained their HGE status.

Different factors have significant impact on the development of the Polish Power Exchange and the volatility of electricity contracts prices, which are quoted on this part of energy market. The electricity prices are strongly influenced by such determinants as: the level of turnover volume, fuel prices, weather conditions, the CO2 emission allowance prices, political situation, the changeability of the energy demand level. The purpose of this paper is to examine and compare the volatility behaviour of world crude oil prices and electricity prices established on the Polish Power Exchange (POLPX) in the turbulent period, which covers the subprime financial crisis, geopolitical crisis, and changes in the rules of the European Union's energy policy. The background for the empirical research is a comparative analysis of business strategies of Polish energy companies and their adaptation to the factors that in the significant way influence the development of energy sector in Poland.

In the constantly changing and interconnected business environment characterized by uncertainty and fluidity, building and maintaining trustful relationships where all stakeholders become partners is crucial for fostering growth, innovation, and organizational resilience. To build and nurture long-term business relationships, trust has emerged as a crucial element. Because of that, and because of a high level of business internationalization and digitalization, building trustful relationships require a strategic approach and commitment. Three types of relationships need to be considered when building organizational resilience. The first type is self-confidence (without it, there would be no equality in other relationships), the second type is trust in internal relationships (connections, interactions, and collaborations that occur within an organization among employees, teams, and departments), and final, trust in external relationships (relationships between the management team and employees with consumers, suppliers, competitors, government, intermediaries, media, the local community, and other stakeholders that enable business activities). <!----> <!----> <!----> <!---->
