The increasing pressure of competition in a globalizing world forces the countries that aim to grow rapidly to strengthen their market share. This requires technological innovation, and its primary source is scientific knowledge. Hence, the main aim of this study is to investigate the determining role of the sectoral technology intensity on the impact of international technology spillovers channels on innovation performance. For the aim of the study, 900 observations that belong to 320 firms for the period of 2009–2016 are obtained by matching approximately 350.000 of the survey data of the Business Statistics, Research and Development. Activities and Innovation provided by TUİK. Findings estimated by the System Generalized Method of Moments (SGMM) indicate that technology absorptive capacity has a positive and significant effect on the innovation performance of the firms operating only in high-tech industries. Foreign Direct Investments (FDI) has a stronger effect on firms' innovation performance in low-technology-intensive sectors than in high-tech-intensive sectors. There is no significant difference between sectoral technology intensities in the effect of export activities on innovation performance of firms. On the other hand, technology transfer expenditures have a statistically slightly positive and significant effect only for firms operating in high-technology-intensive sectors. Consequently, the government should support high technology intensive sectors instead of traditional low technology intensive sectors in order to benefit more from the international technology diffusion channels in Turkish manufacturing industry. This strategy can lead to a long-term economic growth.

The aim of this article was to determine the significance of modern marketing communication channels used in the process of shaping the external image of an enterprise as an employer. An analysis of the world literature on marketing, management, marketing communication and human resource management was used to prepare the theoretical part. The results of the analysis indicate a cognitive and research gap regarding the use of modern communication channels for building the external image of an enterprise in the role of an employer. In order to reduce the gap, empirical studies were conducted among young Polish potential employees, in which the survey method was used to gather primary data. The collected data were subjected to statistical analysis, during which the following methods and statistical tests were applied: the analysis of average values, exploratory factor analysis, Kruskal–Wallis test (KW), Pearson chi-square independence test and V-Cramer coefficient analysis. The results of the analyses conducted indicate, inter alia, that statistically significant diversity was identified in the case of non-professional media in terms of respondents’ opinions on whether the employer’s image created by modern media is better than the employer’s image created on the basis of classical marketing communication channels. In the case of professional and non-professional media, the age of the respondents was not a differentiating feature. Moreover, neither for professional media nor for non-professional media were statistically significant dependencies identified between respondents’ opinions on the impact of actions undertaken by enterprises on shaping their positive external image as an employer and respondents’ opinions on whether the employer’s image created on the basis of modern marketing communication channels is more beneficial than the employer’s image created on the basis of classical marketing communication channels. The results obtained on the basis of the research have a cognitive and applicability value, characterized by originality. Until now, the importance of using modern marketing communication channels in shaping the employer’s external image has not been analysed. This also applies to enterprises operating on the energy market.

Internal control plays a role in risk prevention for firms when dealing with serious emergencies, which ensures the sustainable development of firms during a crisis. Based on the rapid outbreak of COVID-19 in China, this paper empirically tests whether internal control alleviates the negative impact of the pandemic on firm performance. Using a sample of Chinese listed firms from the first quarter of 2019 to the third quarter of 2020 and employing the difference-in-difference (DID) method, we find that the firms with a higher quality of internal control achieve better financial performance during the pandemic period; the more serious the pandemic is, the more obvious effect internal control plays. Furthermore, we consider the industry heterogeneity and firm heterogeneity of the risk resistance effect of internal control. In the manufacturing industry, which is a “disaster zone” of the pandemic, and the non-high-tech industry with a low degree of digitization, internal control can play a more important role in firms’ performance. Moreover, for state-owned enterprises, and firms with strong financing constraints, the role of internal control is more prominent. The above results provide empirical evidence for the risk prevention function of internal control and shed new light on the measures for firms to resist emergencies in the future.

The article identifies the key conceptual foundations for the formation of intellectual leadership of economic entities, including countries as specific actors in the global economy. Thorough preconditions for increasing the level of economic development and the impact of education have been identified. It is determined that historical concepts and modern realities of economic activity only actualize the role of education and enlightenment in the economic development of the national economy and ensuring its competitiveness. The strategies of increasing the competitiveness of individual countries of the world are analyzed, their key priorities in the conditions of formation of the knowledge economy are determined. The evolution of views on the role of human and intellectual capital in increasing the welfare of countries, the impact on GDP and other macroeconomic indicators is described. The ratings of countries are analyzed, in particular by the level of investment in intellectual capital and the structure of their GDP, which confirms the dominance of science-intensive economic activities. In addition, it was determined that the leading countries are characterized by increasing the role of knowledge-intensive activities, increasing the share of intangible assets, redistribution of capital of leading international companies and increasing research spending, increasing investment in human and intellectual capital, increasing exports of high-tech products. Analytical assessment confirms the advanced development of science-intensive industries in countries with developed economies, which creates the need for training and retraining of specialists needed for such industries. In modern conditions, the educational process ceases to be predominantly the prerogative of young people, and becomes a lifelong process, which increases spending on education in developed countries, but without denying the significant asymmetries on this indicator. Research confirms the direct relationship between the quality of human and physical capital and economic development, which is typical of highly developed countries, one of the main reasons for the development lag of the poorest countries. In addition, the article substantiates the key factors of intellectual leadership and their impact on the development of economic development strategies.

Abstract: The article deals with new type of asymmetric warfare and hybrid war. The potential threats in international politics and global security issues, Euro-Atlantic Alliance policy of fighting against terrorism. A serious challenge to modern security creates many problems around the world. The beginning of the twenty-first century was marked by proliferation of hybrid wars, held between flexible and sophisticated adversaries engaged in asymmetric conflicts using various forms. The hybrid war is caused by a hybrid threat, a blend of military and non-military assets and operations, terrorism, guerrilla tactics, criminality and cyber attacks. The use of hybrid type tactics can ensure the achievement of the main objectives of an international actor, with a minimum of effort, usually without using the force, and can deny to the target/victim the possibility to take any defensive actions. The complexity, diversity, the nature and dynamics of contemporary conflicts represent challenges that should be widely studied. The war, be it ancient or modern, hybrid or not, is always complex and cannot be described by a single adjective. The work focuses on the role of NATO in ensuring peace worldwide in the context of new asymmetric threats. The aim of the research topic: analyzing global challenges, which pose a serious threat to international security.

One of the most current concerns in the field of information system is whether cloud computing technology can deliver the desired improvement of capability and value to enterprises. This paper studied the enterprise technology development capability of the enterprises in Beijing Zhongguancun Technology Park, the first national high-tech industrial development zone in China, from the perspective of the breadth and depth of the alignment of cloud computing and enterprise. It proposed a theoretical model to study how the breadth and depth of alignment affects the enterprise technology development capability in a turbulent environment and considers the intermediary role of the enterprise technology absorption capability and the moderation role of environmental turbulence in it. The model was tested empirically by questionnaires and structural equation model (SEM). Empirical results showed that both the deep and wide alignment of cloud computing can enhance the enterprise technology development capability by improving the enterprise technology absorption capability.

The book starts with an introduction to theoretical foundations of knowledge management concepts, proceeds with a series of empirical studies on the role of technology in knowledge management, followed by studies of socially orientated knowledge management solutions. The book ends with the discussion of major issues and challenges for knowledge management research and practice. With its integrated and systematic approach, the book makes a small but important step in helping individuals and organisations to get an objective and complete picture of the role of social and technical initiatives in knowledge management based on formal and sound empirical research. More importantly, the book shows that the impact of various initiatives is highly contingent upon the context in which the knowledge is generated, transferred, and used. This may help managers to choose more suitable solutions to turn their intangible assets into tangible outcomes.
