  MANAGERIAL TIES AND OPERATIONAL PERFORMANCE OF TOURISM BUSINESSES IN VIETNAM: THE MEDIATING ROLE OF RESOURCE ACCESS

  The outbreak of COVID-19 has a negative effect on the operational performance of tourism business. Thus, many tourism firms have stopped operating. Therefore, social networks and access to external support resources are crucial in overcoming the crisis.

Thus, many tourism firms have stopped operating. Therefore, social networks and access to external support resources are crucial in overcoming the crisis. This study, which is grounded in social network theory, attempts to assess how managerial ties affect operational performance through the mediating function of resource access (RA). The study uses the structural equation modelling (SEM) methodology and includes 212 managers from Vietnamese tourism companies in its sample. The findings show a positive and significant relationship between business partner ties (BPT) and government agency ties (GAT) and operational performance (OP). The study also investigates RA's partial mediating function between GAT, BPT and OP. The results are practical for managers in building relationship networks to increase RA and improve OP. Finally, this study suggests certain limitations and outlines directions for further research.

Background: Web application development is a difficult and complex task. The complexity is mostly expressed in the multitude of tasks that must be performed in the development life cycle. In today's environment, it is important that web applications prove their security and resilience in a changing cyber environment. For these reasons, web applications should meet a number of requirements in the process of their technological implementation, which is explored in the article. Methods: The methods used are related to a literature survey on the cyber security requirements of web applications and the characteristics of their life cycle. On this basis, basic key issues of vulnerability testing of developed systems in business organizations have also been studied. Results: As a result of the development of the methodology its main components have been tested in the development of web applications. The achieved application protection levels as a result of the implemented measures have been reported and analyzed. On this basis, some possibilities for improvement of the proposed methodological components are outlined. Conclusions: As a result of the studies and analyses basic conclusions have been drawn about the possibilities for developing and implementing secure web applications in business organizations.

  ECONOMIC, SOCIAL AND ENVIRONMENTAL ANALYSIS OF THE DEVELOPMENT POTENTIAL OF NORTHWEST AND NORTH CENTRAL REGION IN BULGARIA

The establishment of trends and intensity of ongoing processes is important for revealing the causes and differences in the development of regions, the disproportions that have arisen and the need to apply adequate measures for their reduction and limitation. In today's economy, undergoing increasing transformations towards sustainability in each of the developing sectors in Bulgaria and especially in the sensitive regions, sustainability in the context of sustainable development is becoming even more important. Two of the poorest regions in EU are located in Bulgaria – the Northwest and the North Central Region (NWR and NCR), and this is the main reason to analyse the indicators characterizing their economic, social, demographic and environmental condition in this article. The main objective of the study is to analyse important indicators for two of the statistical regions in Bulgaria (NWR and NCR) related to the current vision for their economic, socio-demographic and environmental condition. The study found that, unfortunately, the negative trend of the NWR and the NCR being the least populated regions in the Republic of Bulgaria is still growing, where the population in the NWR manages to stay within the upper limit, while the NCR is emerging as the region with the fastest depopulation. Enterprises with high risk potential have a larger relative share in the NCR, and those in the NWR have lower values. The higher relative share of enterprises with low risk potential in the NWR indicates the possibility of increasing sustainable territorial development and connectivity between different territories, between urban and rural areas. A sustainable trend is observed towards reducing the carbon dioxide values in the sectors of construction, energy, industry and waste. The same trend is noted for methane in the sectors of agriculture, construction, transport and waste, and for the nitrous oxide component in the agriculture, construction and energy sectors. Alarming is the trend in both studied regions for increasing values of CO2 in the agriculture and transport sectors, and of methane in the energy and industry sectors.
