Children in the modern environment are increasingly becoming active users of digital technologies. In a digital environment, they communicate with their peers, watch video content or have fun playing digital games. However, their inexperience can often expose them to malicious activities from other Internet users, such as cyber-harassment. Cyberbullies can be individuals or groups that use audio and/ or visual content to single out a child as a target for abusive and harassing behaviour (for various reasons). Such activities can have long-term consequences for children (anxiety, depression, low self-esteem, suicidal thoughts), especially if they last for a long period of time, and if the children do not see a way out of such a situation. Parents have certainly been identified as the first line of defence against cyberbullying. By talking about children?s digital activities, playing digital games together, and constantly monitoring children?s behaviour in the digital environment, it is possible to detect the problem in time and protect children?s digital safety. Also, companies that produce digital games, with the development of adequate software, and initiatives that punish the disturbing behaviour of cyber bullies, but also praise the fair and sporting behaviour of other users, contribute to suppressing such phenomena. The subject of this article refers to the analysis, identification and prevention of cyber harassment to which children are exposed in the virtual environment, especially while interacting with other players in the process of playing digital games. The aim of the paper is to point out the problem of cyber harassment of children and to let the general public know that more attention must be paid to this problem.

One of a political leader's key responsibilities is to persuade the populace to support a particular political position. The chapter's focus is on a study into the qualities of political leaders required for effective national management. Politicians, however, hold positions of leadership not only at the highest levels of government but also at the levels of local self-government and municipalities. The chapter tries to highlight the key issues that effective local self-government or municipal political leaders are defined by resolving. Sustainable management, which considers both the human factor in terms of ethical standards and political behavior, is today's model of successful management. The chapter will treat Serbia as a country that has recently begun to pave the way toward sustainability.

As a country, Serbia is paving the path for membership in the European Union - facing many complex challenges, where a significant place belongs to the solution of environmental protection and sustainable development problems. Approaching these challenges effectively contributes to regional cooperation in the field of resource utilization for sustainable development, as well as for the improvement of the health of all citizens. In the scope of economic branches, specific forms of tourism business: ecotourism, rural tourism, health, and recreational tourism, could be of great importance for financing the protection of sensitive areas, i.e., the socio-economic development of the population in Serbia. The subject of the chapter is the research and development of regional cooperation that affect the tourism sector of Serbia, with an emphasis on health tourism. The aim of improving regional cooperation is to achieve a more successful business in the field of tourism, especially in specific tourism branches, such as health and recreational tourism.

Using the strength of a single-valued neutrosophic set (SVNS) with the flexibility of a hesitant fuzzy set (HFS) yields a robust model named the single-valued neutrosophic hesitant fuzzy set (SVNHFS). Due to the ability to utilize three independent indexes (truthness, indeterminacy, and falsity), an SVNHFS is an efficient model for optimization and computational intelligence (CI) as well as an intelligent decision support system (IDSS). Taking advantage of the flexibility of operational parameters in Dombi’s t-norm and t-conorm operations, new aggregation operators (AOs) are proposed, which are named the SVN fuzzy Dombi weighted averaging (SVNHFDWA) operator, SVN hesitant fuzzy Dombi ordered weighted averaging (SVNHFDOWA) operator, SVN hesitant fuzzy Dombi hybrid averaging (SVNHFDHWA) operator, SVN hesitant fuzzy Dombi weighted geometric (SVNHFDWG) operator, SVN hesitant fuzzy Dombi ordered weighted geometric (SVNHFDOWG) operator as well as SVN hesitant fuzzy Dombi hybrid weighted geometric (SVNHFDHWG) operator. The efficiency of these AOs is investigated in order to determine the best option using SVN hesitant fuzzy numbers (SVNHFNs) in an IDSS. Additionally, a practical application of SVNHFDWA and SVNHFDWG is also presented to examine symmetrical analysis in the selection of wireless charging station for vehicles.

Arsenic and toxic metals can reach food and honey through water and air, thus endangering the safe consumption of the same. These toxic substances can damage human health through the food chain, which is contrary to the goals of sustainability related to health and food safety. It is necessary to continuously control and measure the concentration of pollutants to ensure the safety of food produced near mining areas. The arsenic content of honey samples from a territory up to 32 km in diameter from the mine (Bor town, east Serbia, and its surroundings), as determined by ICP-MS, is presented in this paper. PM10 particles and water were also analyzed for arsenic content. Pearson’s correlation and hierarchical cluster analysis were used for statistical analysis. The obtained results showed that the content of arsenic in honey was below the maximum allowable concentration (MAC) value. The honey was not contaminated, although the results showed that the concentrations of arsenic in water and PM10 particles were elevated. The results indicate that the environment in these areas is damaged and point towards caution.

The “speed” of modern business—as well as changes in the environment—have led administrative organizations on the path of additional challenges. These organizations tirelessly strive for the realization of advanced systems, adapting their business to modern ideas and trends and gaining market advantage. In this way, organizations become modern and contemporary in their understandings of internal functioning. The study presented by the authors in the chapter aimed to determine the impact of human resource management (HRM) functions on the balanced scorecard in Jordanian public joint-stock companies. In the research, adequate statistical and descriptive methods were used. The results of the study recommend the creation of an organizational culture that promotes the optimal and effective use of HRM functions in the organizational environment.

The aim of this study was to investigate the influence of aqueous extracts of different plant species on the grain and protein yield of soybean. The testing was conducted at the Institute of Field and Vegetable Crops in Novi Sad on the seeds of the NS Apolo variety. The aqueous extracts of the above-ground part of nettle, the above-ground part of nettle and comfrey, whole banana fruit, banana peel, onion bulbs leaves, the top parts of willow twigs and the top parts of soybean plants were foliarly applied. In addition to the untreated control variant, the experiment also included a distilled water control. Control with distilled water was to show whether the effect of aqueous plant extracts was due to plant material or just water. The results of the experiment showed that the use of aqueous extracts contributed to the increase in grain and protein yield. The increase in grain yield ranged from 9.48% to 15.34%, and the increase in protein yield from 9.31% to 16.16%. The best effect was achieved by applying the aqueous extract of the whole banana fruit and the aqueous extract of the mix of nettle and comfrey. By applying them each year, a significantly higher yield was achieved in relation to the control with distilled water.

Cement paste is an already well-known material used in ore mining. It is mainly used to fill excavation areas and the tailings from the surface return to underground mines. In this way, the amount of deposited material and degradation of the surface of the terrain are reduced. The paste itself can be used as an artificial barrier between mining works and underground watercourses. Significant economic and environmental benefits can be expected from using cement paste, which would contribute to sustainable development. The basic materials that make up cemented paste backfill (CPB) are flotation tailings, cement, and water. For CPB to be adequately and safely applied to the filling of excavation spaces and indirectly to the protection of the groundwater, environment, and sustainable development of the mining industry, it must meet certain physical–mechanical, physicochemical, and deformation properties. This paper presents the results of synthesized and analyzed samples of different compositions based on flotation tailings (from the production of ZiJin Copper in Bor, Serbia), cement, and water. The methods used for chemical and mineralogical tests include inductively coupled plasma atomic emission spectroscopy (ICP-AES), atomic absorption spectroscopy (AAS), X-ray diffraction analysis (XRD), and nephelometric turbidity units (NTUs; turbidimetry). The results prepared with CPB consisting of 5% cement, 24% water, and 71% flotation tailings were the most acceptable.

Poverty has become one of the most important categories of the global social and economic order and thus part of sustainability. Poverty is a product of harmful and excessive inequalities in the world as well as in almost every individual society. The aim of the chapter is to point to the importance of poverty indicators in the Republic of Serbia, as well as the impact of uneven regional development on poverty. Therefore, for Serbia, as well as for other countries in transition, it is vital to ensure sustainable and dynamic growth of real per capita income. The chapter also provides an overview of developing strategic directions for poverty alleviation.

The acceleration of contemporary and influencing changes in the future of administrative organizations has imposed on these organizations new, added challenges, which are evident in their relentless pursuit of realizing, absorbing, and introducing advanced systems adapting to modern ideas and trends, which give organizations the modernity and development character. The paper's study sought to determine the impact of human resource management functions on the balanced scorecard in Jordanian public joint-stock companies. Appropriate statistical methods were applied to the research process. In light of the results obtained, the study recommends the need to work on creating an organizational culture that promotes the optimal and effective use of human resource management functions in the organizational environment. Upgrading these functions to the desired higher levels, achieving compatibility between design and analysis of work with organizational structures, can provide incentives for employees and develop business procedures to improve the balanced scorecard of the organization.

In the development of adverse working conditions (AWCs) both inside and outside organizations, various behavioral factors begin to decline due to such circumstances. The conventional paradigm exploits the view that in conditions of crisis and radical changes in the organizational environment, working conditions significantly deteriorate, as well as the response of employees to such forces. It is a fact that COVID-19 has completely transformed the job delivery process, the interaction between employees, as well as employees expectations, and business stability. Although working conditions during the pandemic period are undoubtedly worse, this research reveals employees perception that adverse working conditions are not a strong indicator of reduced job satisfaction, as well as job quality and employees loyalty. This position can open new entrepreneurs perspectives in understanding the employees response that will enable the positive behavioral continuum in full contribution to more effectively achieving the organizational goals in turbulent times.

The development of telecommunication technology in the last three or more decades has created the conditions for high quality and high speed data transmission between physically separated devices (central computers, terminals, mobile devices). Telecommunication can be defined as the electronic connection of physically (geographically) remote computers, and the telecommunication system as a component of compatible telecommunication devices connecting physically separated devices that can transmit text, image, audio and video information. The paper focuses on the choice of telecommunication providers in Serbia. It examines the attitudes of service users and what influences their choice of a particular mobile network. Consumer attitudes can influence the improvement of service management of mobile operators in Serbia. The paper represents a modest contribution to the use of telecommunication technologies to improve the existing offer on the market of mobile operators in Serbia and especially in the eastern region of the country. The city of Zajecar, the largest city in the eastern region of Serbia, is included in the study as a representative example.
