Servant, Ethical and Authentic Comparative Analysis of Leadership Styles in the Light of the Challenges of the BANI World
43-52Views:376In a globalised and accelerated economy, managers are under increasing pressure to reconcile organisational goals that are independent from human being with the reality of human relationships. The human being, as a being with intellect and senses striving towards happiness, is the focus of positive leadership styles and is their major concern in the field of management theory. In this article, three such positive styles, authentic, servant and ethical leadership principles and their operating conditions are compared using international literature. The literature time span of about two decades shows that the evolution of the ethical leadership literature has slowed down, while the authentic and servant leadership literature has continued to evolve and is still evolving today. The comparative table that appears in this study highlights both commonalities and distinctions, in that, in addition to high moral and ethical standards, the authentic style focuses primarily on the person of the leader, the ethical leader on the ethical standards of the organisation, while the servant leader focuses on the development of the well-being of the subordinate, the other person, even through self-sacrifice. We intend to use the results of this research to investigate measures of positive styles, preparing the scientific ground for future primary empirical field studies.

Classification of Nanomaterial’s Risky Properties on the Aspect of Human Safety
34-45Views:332Due to their unique properties the application of nanomaterials continuously extends thus these appear for several industries. The industrial application of nanomaterials became significant during the last decades. As a result of the intensive development, our knowledge about the exact influence of nanomaterials for living bodies and human health is characterised by deficiency for both short and long time. Nanomaterials able to be entered to the living organism through several ways then invade to the circulatory system and the lymphatic system, reach the organs and can induce various kind of damages and serious diseases as a result of their different appearance, physical and chemical properties. Legislation in Hungary and in the European Union seems to be incomplete. There is no document which summarizes and details the risky factors and parameters in case of a risk assessment. Our aim was to develop a criterion system considering the risks related to the use and contact of nanomaterials based on their physical, chemical and biological properties, which criterion system could provide basic principle for a risk assessment thereby make the industrial processes safer both for the employees and those who are in the vicinity.

Do Changes in the Economic Role of States through Privatization matter?: The Brazilian Case
125-136Views:310In market economies, the subject of scientific research is the extent to which the state can contribute to the sustainability of development. However, the question is to know where the boundaries of the market and the role of the state lie. The study briefly introduces different views of the state's economic role and how states have changed the proportion of their entrepreneurial assets. Among these, it highlights privatization, which is one of the significant segments of today's economic policy practice at both micro and macroeconomic levels. It then describes Brazil's economic circumstances that led to the formulation of a proper size privatization program.

The Middle East perspective of Corporate Social Responsibility
282-291Views:493Corporate social responsibility (CSR) in the Middle East is gaining more importance than in the past. Although it still remains more about philanthropy and charity, it moves towards a more strategic approach which includes formalizing ways of giving, as a set of non-random actions, and focuses more on addressing social ills and environment, economic challenges, that are hindering development. However, the business in the region has not yet taken the step to fully integrate the CSR into their core business operations. The most common challenges that facing the CSR implementation are the lack of government requirements and incentives, spreading awareness, building CSR partnership model, going beyond the marketing and PR campaigns, and full integration of CSR into the business strategy. In this paper, we aim to introduce the current state of the CSR in the Middle East and its perspectives, besides reviewing its evaluation stages, motivations, and current challenges. Moreover, we aim to examine CSR common practices through examples from the financial sector. The research method applied in this research is based on secondary data sources and we have used desk research to illustrate most important points and findings on the topic.

Analysis of Social Media Activities - Through the Examination of Handball Clubs Competing at Different Levels
39-53Views:607In Hungary, handball enjoys special attention and support, this is true not only for our country, but also for Europe, and the sport is gaining more and more space worldwide. One of the biggest innovations of the last two decades is certainly social media, which has reformed the basic strategies related to information transfer and traditional marketing activities. The processes of content production on these platforms have radically changed, which every sports club should pay attention to, as they can gain significant advantages in terms of economics, marketing and community building if they are able to communicate well. Three sports clubs competing at different levels were compared during a qualitative study in terms of their social media marketing strategy activities, namely PICK Szeged, Balatonfüredi KSE – BFKA Balatonfüred and DEAC handball team. The basic concept of this research model was built on how the online marketing communication activities of club teams fighting for different professional goals at different levels differ from each other, as well as what are the development opportunities and aspects that can be used as effectively as possible on social media platforms. The handball club teams agreed on several research questions, but a significant difference could also be discovered in one area, in which the professionals responsible for social media disagreed or represented a different point of view. Looking at my results, it can be concluded that behind a successful online marketing strategy there is always serious preparation and planning work, as well as the diversification of content production on different platforms, because the consumer communities of the platforms are also different from each other.

Introduction to Design and Analysis of Torsional Vibration Dampers in Vehicle Industry
310-324Views:529The crankshaft of today’s internal combustion engines with high performance output are exposed to harmful torsional oscillations originated from the unbalanced gas and inertial forces. To avoid the fatigue damage of engine components, caused by the undesired vibrations, torsional vibration dampers can be applied. Viscodampers are one type of the torsional vibration dampers, which operational fluid is silicone oil. For cost-effective R&D activities and production, finite element and finite volume numerical discretization methods based calculation techniques must be involved into the engineering work supported by the modern computer technology. The aim of this paper is to provide an insight into the multidisciplinary design and development process of visco-dampers in vehicle industry applications. Four different examples as structural, fatigue, CFD analyses and structural optimization have been introduced in the present work. It turned out from the static structural and fatigue analyses, that the investigated damper has safety factor over the limit for both static structural and fatigue analyses, so it is suitable for the given load conditions. In the structural optimization process 34.36% mass reduction has been achieved. According to the coupled fluid dynamic and heat transfer simulations a rather stagnating air zone evolved between the engine and the damper during the operation, which can cause efficiency reduction of cooling fins mounted onto the housing. In light of the numerical results, the suitable damper position has been determined for the highest heat transfer.

Examination of road sections in Debrecen by noise mapping
287-295Views:212During the research, noise level calculations were performed for 13 numbered roads in and around Debrecen and a noise map analysis was conducted on the roads’ environment. The first examined year was 1995, the last was 2017. In the time interval, annual status was determined based on average daily traffic data. In addition to the road noise values calculated for each section, a noise map was prepared for each survey year. For the evaluation of the results a difference map of the highlighted periods was prepared. Typically, noise level increase from road sources was identified between 1995 and 2017 in a significant part of the studied area (southern and eastern parts of Debrecen and around the newly built roads). Stagnant noise level was diagnosed near the downtown of Debrecen and around the main road No. 4, furthermore in some places noise reduction was caused by the development of the road network (between Debrecen-Józsa and Hajdúböszörmény, between Debrecen and Látókép around road No, 33, and along roads No. 4808 and No. 4814) .

Comparing higher education preferences with labour market needs
382-392Views:531Hungarian institutions of higher education play an important role in national economy: they ensure intellectual labour with appropriate knowledge and professional competencies for Hungary in all profession fields. If the rules of private sector are applied for these institutions – interpreting it within a certain framework as the quality of education and research has to be maintained and there are social benefits associated with them -, they owned by the state, their management is the institutional leadership and their consumer is the labour market. Thus, training programmes must or should be developed in accordance with the needs of labour market. It represents a major challenge, even without taking into consideration other factors, since future requirements should be aimed (at least a 3-5 year training period later) – along with a rapid technological development. Even if the state makes significant efforts to adapt training programmes to meet the requirements of the labour market demands, students who want to further their education pay limited attention to these factors in their educational decision-making. Partly for this reason, career transition or shortages may occur in the case of certain professions. This paper seeks to address to what extent the most popular training programmes meet the expectations and to what extent the degree earned may be regarded as a ‘success’ in the labour market; moreover, if they do not overlap each other, how much applicants prefer those training programmes which are to be considered the most successful based on recruitment information. Admission statistics of Education Department and database of DPR provide the necessary information for the period 2010-2017 and these data sources enable authors to follow-up students from application to higher education until employment.

Examining the Virtues of Organisational Citizenship Behaviour (OCB) at an SME
41-52Views:355Nowadays, especially in the Eastern region of Hungary, small businesses face an increasing challenge in attracting and retaining a well-qualified workforce that is able to accept and commit to the goals of SMEs. This is due to the promising career prospects offered by foreign-owned large companies locating here. However, if SME employees possess the virtues of organisational citizenship behaviour (OCB), they will develop a stronger commitment to the organisation. The aim of our research was to explore the extent to which the five OCB virtues; sportsmanship, conscientiousness, altruism, politeness and civic virtue are present in a small construction company in Hajdú-Bihar county. Our survey was carried out using a questionnaire method, which was analysed as a function of length of service, education and age. The main findings are that there is a strong correlation between the presence of OCB characteristics and age and length of time spent with the firm.

Examination of the Informative Part of the Notes to the Financial Statement Amongst Hungarian Companies Engaged in Sports Activities
108-116Views:348Currently, the role of sports has intensified and changed; by now, it has become a separate area of interest from an originally civil, exercise-based, private leisure activity. In the case of sports-related economic research, both macro- and microeconomic research can be mentioned. Its economic significance, its contribution to employment, national economic income, and consumer spending is involved in macro-level research, while the examination of the functioning of sports services and organizations, and the characteristics of demand and supply are micro-level research activities. One of the reasons for the development of sports activities was the increase in their economic significance, which created a need for their economic analysis. The necessary information can only be obtained from the two fundamental parts of the annual statements (balance sheet and profit and loss account) if the notes on the account contains the information that contribute to the more comprehensive interpretation of the other parts of the annual statement. In our research, we examine whether the notes on the accounts of companies include the information, which could help obtain necessary financial knowledge concerning the partner companies. For the analyses, we used the notes on the accounts of companies, which have sports activity (Hungarian NACE No. 931) as their main line of business. By means of text mining, we analyse the extent to which the notes on the accounts are in conformity with the Accounting Act.

Challenges of the Quality- and Change Management in the Context of Upcoming Social-Industrial Changes (5.0) – Conclusion of a Survey
138-150Views:362The upcoming industrial-social revolution, which may be called the 5.0, is emphasizing the coordination of the value-creating work of technology (machine) and man. This approach wishes to move towards sustainability, which deserves a significant role in nowadays through the world empathizing the negative effects of the wolrd. During my research I was looking for the answer that how the extended industry 4.0 and its tone be in Hungary via supply chain of the automotive industry. During my research I was looking for the answer that how the extended industry 4.0 be in Hungary and its tune through supply chain of the automotive industry. I also have examined that which changes are justified regarding management systems in interest of efficiency and emphasizing the human capital by leaders interviewed. As a part of qualitative research in-depth expert interviews were interpreted with help of content analysis based on the methodology of grounded theory. The results demonstrate the need to review and change existing processes in order to ensure that the potential of human capital is not lost and that technological development, even more so, is at the service of human resources in order to achieve its efficiency and effectiveness. Among the possible tools we can find the re-structurizing changes of post tracking processes of the audits in management systems providing quality. Furthermore, the practical implementation of multifactorial statistical process control in the evaluation of processed data, which may be one of the essences of industrial (IoT) data.

Volunteering in Sport
217-230Views:769The subject of our research was the examination of the sports ambition and its motivational background. Our aim was to examine the volunteer experience of young adults in volunteering. Our goal was also to analyze the areas in which sports are chosen most voluntarily and what motivates them in sport. The basis for our questionnaire research was the concept of volunteering "4 W" (who, what, where, why). The questionnaire was designed to answer these questions in relation to sports ambition. The data of the questionnaire completed by 371 young adults (mean age = 23.93, sd = 9.93) were analyzed using SPSS statistical software, where we calculated basic statistics (mean, standard deviation, median, mode) and Chi2 test. More than 75% of the respondents have already worked as volunteers. One of the most popular areas of volunteering was sport. The most frequented volunteering area was among schoolchildren and students as well as university sports among young people, after which the area of competition and recreational sports proved to be the most popular. The main motivation of young volunteer workers was the following, : „I had a good mood”, „I loved sport”, „teamwork”, „work experience”, „learning and skill development” and „career perspective”. Organizations, marketing and communication areas in the field of sporting events and sportsclubs volunteering were the most popular in the area where the respondents had experience. A significant difference was found in the field of organizing and marketing volunteering in sports events, 61% of Hungarians worked, while respondents from other countries were only 34.2% (p <0.05). In the field of communication, higher values of respondents from other countries (45.7%), compared with Hungarians (33.7%) (p <0.05).

Issues of Regional Social Innovation
602-616Views:396Social innovation is not determined as a uniform definition, after a literature review can be defined as follows: social innovation is an innovative and new way of improving community well-being [2]. Social innovation can be defined and measured at micro-, mezo- and macro level similar to technical and economic innovation and plays a key role in the competitiveness. Because of imbalances arising from different levels of economic development, catching-up demand of peripheral settlements have appeared. In addition to the so-called technical innovations, the solution of social problems can be achieved by social tools, methods and new organizations. In catching-up process the local, community level construed innovative ideas and the activities of social innovation play a significant role. The expansion of the innovative areas results in different innovation processes and they can be considered as complementary processes. The social and technical innovation are closely interacting. If there is achange in the economic sphere, social change can occur. This study examines the role of local communities in social innovation at regional level and summarizes the clarifying questions of implementation. Social innovation as a new tool is able to answer daily challenges. The innovative solutions of municipalities, which means new collaborations, result sustainable, flexible and open leadership at regional level. This study will examine the role of governments (or their institutions) in the implementation and generating of social innovation, the tasks of regional innovators and social solutions and models of certain municipalities in Hungary and the European Union.

Digitalization Process by Agricultural Companies, or the Results of a Questionnaire Survey
625-636Views:397The term “information society” first appeared in Japanese social science in the early 1960s (Z. Karvalics, 2007). The interpretation of the concept has undergone significant changes over the past decades, showing that dynamically developing societies, which are undergoing constant changes due to the rapid development of information, information management and the dynamism of the digital world. The close relationship and connection between information and information technology has become a fundamental factor in the societies of today, the organizations life, which generates inevitable, sometimes serious debates and profound changes. Economic operators must necessarily be resilient to technological change. We should think of the time of the Industrial Revolution, when modern weaving machines flooded the factories. Otherwise, a resilient organization will not survive in an evolving and ever-changing dynamic economic environment. Of course, this is true of agriculture as well, just as it is for other sectors of the national economy. On the one hand, my assumption on the basis of which my questionnaire was compiled was that enterprise management systems are increasingly used by enterprises in agriculture due to the diversification of activities. At the same time, I assumed that the size of a business could influence the use of information technology (hereinafter IT), so I hoped that my research would provide reliable data on this as well.

The Impact of Optical Character Recognition Artificial Intelligence on the Labour Market
9-16Views:542Because of present day information technology, there is neither need to plant complicated computers for more millions price if we would like to process and store big amounts of data, nor modelling them. The microprocessors and CPUs produced nowadays by that kind of technology and calculating capacity could not have been imagined 10 years before. We can store, process and display more and more data. In addition to this level of data processing capacity, programs and applications using machine learning are also gaining ground. During machine learning, biologically inspired simulations are performed by using artificial neural networks to able to solve any kind of problems that can be solved by computers. The development of information technology is causing rapid and radical changes in technology, which require not only the digital adaptation of users, but also the adaptation of certain employment policy and labour market solutions. Artificial intelligence can fundamentally question individual labour law relations: in addition to reducing the living workforce, it forces new employee competencies. This is also indicated by the Supiot report published in 1998, the basic assumption of which was that the social and economic regulatory model on which labour law is based is in crisis.

Operating a Webshop in Rural Areas
242-251Views:362The importance of e-commerce in Hungary is unquestionable. 66% of the population is regular internet users (I3), every fourth person uses it on a daily basis. Online sales have increased from 137 billion HUF in 2010 to 427 billion HUF in 2016, while offline sales were not able to reach this growth (I1). Undoubtedly, online sale has become a very valuable market. The age group really valuable as consumers spends about 6 hours a day online, out of which 3 hours are active usage (I2). The Internet is also the most important source of information and keeping in contact, as 41% of the population uses it method. The availability of the Internet in Hungary is literally independent of the geographic location, thanks to the Digital Renewal Action Plan in Hungary's current strategy, as one of its main chapters is "Enhanced and Secure Infrastructure for All." (Botos 2013) plan. There are many unfavorable processes in Hungary's rural areas. Of these, emigration and the abandonment of the local economy are outstanding. To stop these processes, the "National Rural Strategy" (2012-2020) was created. Its most important areas are employment growth, balanced and diverse land and forest management, production structure, restoration of local food production and food markets, local energy production, strengthening the local communities, improvement of population patterns and conservation of natural systems and the biodiversity. The integration of rural economies into the on-line marketplace and their linkage to different DBEs not only vertically but horizontally can be one of the keys to their survival and development. The situation of businesses on the on-line marketplace in the countryside is very special. On the one hand, they are more favourable in many aspects of their operation, but in some cases they have disadvantages that fundamentally threaten their survival. The purpose of this article is to get to know this environment, map its benefits and drawbacks. For this, we use the results of in-depth interviews conducted with businesses operating on an on-line market in rural settlements.

Enhancing Sustainable Production Through Continuous Improvement: Evidence from Nigeria’s Manufacturing Sector
1-20Views:125The manufacturing industry in Nigeria has been the so-called cornerstone of economic development since the sector has continuously played a major role in providing jobs and industrial capital. However, there remain issues that impede its progress, including inefficient resource use, unstable regulatory systems, and the need to comply with international market requirements. Specifically, it examined the effect of employee engagement, process efficiency, and resource allocation on Nigeria’s manufacturing sector. A survey research design was adopted, with a total population of 117 employees across five manufacturing firms. A total of 91 participants were administered a structured questionnaire. Data collected was analyzed using PLS-SEM. Findings revealed that employee engagement has the strongest effect on sustainable production (β = 0.412, t = 6.250, p < 0.000), followed by resource allocation (β = 0.237, t = 3.610, p < 0.000), and process efficiency (β = 0.174, t = 2.877, p = 0.004). It concluded that continuous improvement is significantly vital for sustainable production in the five sugar manufacturing firms studied in Nigeria. It is therefore recommended that management of these selected firms focus on developing unique resource allocation strategies, employee engagement, and process efficiency to ensure sustained workforce improvement, thereby achieving sustainable production outcomes.
