The significance of analysing potential conflicts in the sales-marketing integration
41-59Views:265Our research aims to identify the critical interfaces between sales and marketing that need to be improved in order to ensure productive cooperation. The relationship between the two departments is full of conflicts and interdependencies. The improvement of communication is of strategical importance, as it is key to staying competitive in the market. The effectiveness and quality of the sales-marketing cooperation is a key factor that is negatively affected by personal and organisational factors as well as a lack of information and conflicts. In addition to the key factors of managing the sales-marketing interfaces, we have also identified the actions that can promote their improvement, including strategic and organisational roles and responsibilities. Our empirical research results show that regular information exchange, more common and interdisciplinary meetings, and a clearly communicated and implemented corporate vision have a positive effect on the coordination and integration of the sales and marketing departments. Consequently, management is reponsible for establishing a corporate vision, i.e. a comprehensive management culture that is clearly communicated across the board in order to increase the employees’ sense of belonging. Of all elements of management culture, the most important factors are coordination and the establishment of a common strategic sysyem. All in all, corporate profit, which is of key importance to the employer, is largely dependent on the successful integration of the sales and marketing departments, which can be achieved through the implementation of the above factors.

Evaluating the Entrepreneurial Performance in South America. Case of Chile
13-28Views:427The research objective is to explore Chile's entrepreneurial landscape by assessing individual characteristics and institutional factors through a 'pillars' framework and compare it against Colombia, and Brazil; to identify socio-economic, individual, and institutional differences using the Global Entrepreneurship Index (GEI); to apply bottleneck approach to highlight areas requiring policy intervention. GEI features individual and institutional stage variables in a method where every variable collaboratively interacts, incorporating 14 foundational elements and three sub-indexes: attitudes, abilities, and aspirations. Ranking 18th on the GEI globally and the best in Latin America, Chile excels in key entrepreneurial pillars, showcasing strengths in innovation and a robust entrepreneurial culture. Brazil closely rivals Chile in competition and networking, emphasizing political and economic influence. Colombia surpasses Chile in internationalization and growth-stimulating policies but faces challenges like historical conflicts and wealth distribution. This study identified areas where immediate policy intervention may be necessary by examining Chiles's entrepreneurial ecosystem. The Penalty for Bottleneck (PFB) technique identified the weakest pillars highlighting process innovation, competition, and internationalization. The primary component identified as a bottleneck for resource allocation is Process Innovation, accounting for 73% of the allocation, followed by Competition at 23%. The findings show that allocating more resources to process innovation may improve greatly the overall GEI score.

Application of Nanomaterials in Food Industry and Agriculture
116-126Views:334Nanomaterials have unique application features which can mainly be associated with their size properties. These materials have much higher surface than the normal particle size variant of the same materials. Due to these properties, nanomaterials are widely used in the industry. Food industry and the agrarian sector are using these materials increasingly. The main goal of nano size components and additives are the improvement of some parameters of the food manufacturing process, the elongation of the best before date of the food and the improvement of the texture, stability and the consistence of the food. Probably, nanomaterials will play an important role in the development of the food industry, moreover, it can be anticipated that nanotechnology will also appear there and will influence the whole food chain. It should be noted that food industry is using several nano size class materials which are not referred to as nanomaterials. Some examples are the micelles of some proteins, like milk protein, and fatty acids. Considering all these, the aim of our work was to present a thorough review and summary of the current applications.

Talent Management in International Practice Through the Example of Europe and China
454-464Views:415The reason behind is that they have their own principles, strategic goals and industrial environment that they have to manage on daily bases. The current labour and talent shortage across Europe forces local companies to supply their demand of manpower from foreign countries – encouraged by the ’four freedoms’ of the EU. In consequence of the globalisation, we have to keep in mind that running a talent management system has its challenges. For instance, employees with different cultural background might have unconventional needs. Due to the cultural, demographical and economical differencies, we must know the structure of our labour force to use the most beneficial tools to induct, motivate or retain our human resource. The aim of this research is to analyze Europe’s and China’s talent management systems to reveal similarities and differencies between them and pick the most notable ones. From the point of comparison, analysing China would be important for European countries to discover further possibilities, as nowadays China has one of the most dynamically developing economy with enormous population behind. The primary result of the research is that deficiency of talent is irrespective of the size of the population and it causes difficulty in both European and Chinese fields, therefore it proves to be a real and general challenge needing attention at organizational level. Furthermore, identifying regional patterns considering peculiarities, the framework of talent management systems can be defined and be found summarised in the article.

Ethical Leadership, at the Beginning of a Research
188-195Views:536In this study I deal with the ethical leadership. I give an insight into the approaches of ethical leadership, give a literature review on the concept of ethical leadership, and introduce the measurement methods used in the most important empirical researches related to this topic. I also try to report on the first results of my research (I plan to describe features of Hungarian leaders based on a smaller sample). How does this relate to the challenges of Industry 4.0? I give the answer from the fact that, with the advent of these new technologies (which in themselves have ethical questions), among these new challenges, the focus of the manager's attention will continue to be partly on their employees. If they set an ethical example for their subordinates, they encourage their employees to act ethically, which gives the company a competitive edge in many ways, both in the product/service market and in the labor market too. So, with my study, I would like to draw the attention of executives and managers to the fact that new technologies and the human factor together bring new successes, and that one possible way of doing this is by consciously managing their company ethically and developing an ethical organizational culture.

Advancing Sustainable Waste Management through National Recycling Rate under SDG 12.5.1
61-72Views:488Solid waste management remains a pressing environmental challenge in both developed and developing nations. Recycling has been promoted globally as a key pathway to sustainability, yet recycling rates often provide only a partial picture of performance. In many contexts, challenges such as poorly regulated recycling policies, informal sector dominance, and practices that prioritize profit over environmental sustainability limit progress towards Sustainable Development Goal (SDG) 12.5.1, which tracks the national recycling rate. This study investigates the extent to which recycling rates reflect sustainable waste management and identifies the underlying factors that influence their effectiveness. The major objective of this study is to evaluate recycling rates as an indicator of sustainable waste management. This is further specified by: (i) examining recycling practices in selected countries (Germany, South Korea, USA, Brazil, and India), (ii) identifying key drivers and barriers that influence recycling performance, and (iii) assessing the implications of recycling rates for sustainable waste management systems. The study employed a mixed-methods approach, combining secondary data analysis, comparative country assessment, and policy review. Results show that recycling rates are useful but insufficient as a stand-alone measure of sustainability, since they are influenced by broader elements such as policy enforcement, economic incentives, public participation, and market structures. The findings highlight that Nigeria’s recycling rate remains significantly low compared to leading economies, underscoring the need for integrated waste management reforms. This research contributes to environmental management discourse by demonstrating that while recycling rates provide a benchmark for SDG 12.5.1 monitoring, they must be interpreted alongside contextual drivers to ensure meaningful progress towards sustainable waste management.

Analysis of Social Media Activities - Through the Examination of Handball Clubs Competing at Different Levels
39-53Views:611In 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.

Analysis of Vibration During Turning Process of Different Materials
200-205Views:256In this article, we would like to introduce the problems caused by vibrations in case of polymer turning processes. Nowadays there is a lot of research in this topic, to avoid the unnecessary phenomena of vibrations. The two most common methods are the Spindle Speed Variation (SSV), and the Vibration Assisted Machining (VAM). In case of SSV, the CNC machine can increase and decrease the speed of spindle continuously during turning which can significantly reduce the effects of chatter. This method is beneficial for longer workpieces when there is not any support except the chuck. Vibration-assisted machining can be used to minimise the problems caused by vibrations. VAM combines precision machining with small-amplitude tool vibration to improve the fabrication process. It has been applied to some processes ranging from turning, drilling to grinding. Based on the enumerated above we made some trial measurements about the basic vibrations of the turning tool shank. The tests were done on an NCT EUROturn-12B CNC machine which can found in the workshop of our institute. The tested material was Polyamide 6 because this is the most commonly used polymer in the industry. In the future, we would like to test some other basic and composite polymer materials too. The equipment was served by a specialist from SPM Budapest Kft. With these tests, our goal was to make sure that the equipment and the measuring setup are suitable for our future research.

Global and Domestic Status and Prospects of Green Biomass Utilization
85-105Views:290Nowadays, the energy consumption of global population is depending on fossil fuels, but the role of renewable energies has been increasing rapidly, primarily due to the depletion of fossil fuels, the appreciation of environmental problems and climate policies. Biomass is the fourth most important energy resource in the world, provided an estimated 70% of global renewable energy supply. However, the annual growth rate of biomass is lagging behind modern renewable energy sources. The type of biomass is very diverse and can be processed and utilised by different methods. Currently, in the "green chemistry" industry (the replacement of petroleum-based, synthetic chemical raw materials with bio-based compounds from plant biomass), the importance of combustion, pyrolysis, biogas, bioethanol, biodiesel and basic chemical compounds production have been increasing. The objectives of the present research is to analyse the global and domestic status of renewable energies and biomass production, furthermore the possibilities of utilization of perennial, herbaceous biomass plant, the giant reed (Arundo donax L.), with which has been conducting research for numerous years at the University of Debrecen.

Examining the Competitiveness of Fish Products on the Market
151-163Views:243Fish and fishery products are one of the key ingredients in human nutrition and are therefore outstanding in terms of both production and trade. Different processed fish products are available in many countries around the world due to globalization and a fast supply chain. In our study, we examined the market for fish and fishery products using secondary data collection. The data were collected several years ago from the databases of FAO, EUROSTAT, COMTRADE and KSH The comparative advantages or disadvantages of international trade were determined with the help of the RCA index for the role of Hungary and the EU in the world in the case of different categories of fish products. The aim of our research is to compare the fish products of different processing in Hungary and in the EU compared to the international situation, paying special attention to the main exporting and importing countries. Based on the secondary research the study has a detailed the specificities of trade, the trends observed in recent years and the competitiveness of fish products in Hungary and the Member States of the European Union and effect relationships behind the RCA-index results.

Material flows and stocks of a service company from Debrecen
313-321Views:452Over the past 25 years, many renowned scientists from a number of research institutes have developed a new research method, a new family of methodologies which is the MFA (Material Flow Analysis). The importance of MFA is given by the extent of excited material flows created by mankind. The basis of MFA's growing success is a radically new, interdisciplinary vision that requires collaboration between the natural and social sciences (ecology, thermodynamics, and economics), not only as an effective tool for examining material efficiency of production and environmental pressures, as well as the security of supply of the strategic material requirements of the system under investigation. In our article, we conduct an enterprise level analysis of the input and output side material flows and materials of a service company in Debrecen for 2018 using the MFA method. MFA indicators capture environmental pressures in a natural dimension, that is, in terms of mass, energy, or land, respectively, in terms of kilograms or tons, of the company's raw materials and their changes, or material inputs.

The Location of Energy Plantations in the Sowing Structure and Its Evaluation with Linear Programming
255-269Views:230The research is examining traditional arable crops and woody plants on the basis of their marginal contribution. Calculations of income, expenditure and revenue were made on the grounds of sectoral technologies, which were the basis of the value of marginal contribution of the given sectors. As the linear programming model is quite comprehensive, we used this method for our calculations. To compile our model, we have gathered all the necessary information from farmers of the region of the Northern Great Plain. The missing data was completed from the databases of the Hungarian Central Statistical Office (KSH), Institute for Agricultural Economics Research and Information Technologies (AKII) and the Statistical Office of the European Communities (EUROSTAT). In some cases, we also used data of the Agricultural Administration Office and the Ministry of Agricultural and Rural Development. Our goal is to compile a 12-year production structure that suits for the characteristics of the region of the Northern Great Plain by achieving the maximum marginal contribution of a feature-farm.

Enhancing Sustainable Production Through Continuous Improvement: Evidence from Nigeria’s Manufacturing Sector
1-20Views:134The 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.

The Effect of annealing temperature on corrosion resistance and microstructure of Zr-Sn-Nb-Fe alloy
420-424Views:259The Ti-2Al-2.5Zr titanium alloy plate in beta phase water quench at different times of the reentry after annealing is implemented while primary phase number and size distribution of samples are obtained. This research is carried out on corrosion behavior in 3.5% [mass fraction] NaCl solution. Experimental study showed that after the beta phase water quenching Ti-2Al-2.5Zr titanium alloyed after 500 oC annealing when partial recrystallization happened. There seems to be lots of tiny dispersion in the alloy that was annealed with its samples of six-party [HCP] structure of Ti, Zr, Al phase 2 with the dimension below 100 nm. Reaching 500 oC when the rate of annealing at a primary phase of the sample at 550 oC is low 90% of the primary phase is less than 100 nm. The changing of the rule of present decreasing also triggers little difference overall. Precipitation in the process of annealing Zr [Nb,Fe,Cr] 2is less that proves to be good for corrosion resistance.

Business Students’ Attitude to Social Responsibility
1-10Views:420The companies’ most important goal is the satisfaction of consumers’ needs and the profitmaking. But nowadays the companies have to deal with the activity of corporate social responsibility, too. Therefore it can be interesting to research about the next questions: can ethics be taught? Do we have to teach ethics in the schools and especially in the business schools? What are the students’ attitudes toward the social responsibility? Are students sensitive and open-minded connection with this issues? The aims of the study were to examine responsible management attitudes among business students at the University of Debrecen (Faculty of Economics and Business). We draw their CSR pyramid (based on Carroll model) and present their opinion in reference to business education’s role in social issues.

Millennium Generation Work Experience
657-665Views:389If we are open-minded in our everyday life, we should not overlook the phenomenon of student work. Within the framework of this study, our aim was to examine the work experience, later employment plans and income needs of students starting their studies at the Faculty of Economics at the University of Debrecen. In addition, we analyze the most important sources related to student work through literature studies.
It is important to pay attention to changing attitudes of newcomers to higher education as they become active job seekers after graduation. At the Faculty of Economics of the University of Debrecen, about 1,700 students started their studies in the 2019/2020 academic year. Our research was conducted with the involvement of these students.
The data were collected among students participating in the stork camp organized by the University of Debrecen. The survey covers, among other things, the initial salary requirements, previous work experience, future plans, including the willingness to work abroad, and factors that are taken into account when choosing a job.

Servant, Ethical and Authentic Comparative Analysis of Leadership Styles in the Light of the Challenges of the BANI World
43-52Views:383In 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.
