Examining Organisational Culture with OCAI among Technical Management BSc Students of the University of Debrecen
1-8Views:561Based on the OCAI model, our study analyses and compares two things (1) the corporate culture of the University of Debrecen Faculty of Engineering as it is perceived by its engineering management students; and (2) the culture they think would be ideal. According to the respondents the existing culture is closer to the clan type and further from the market type compared to the average. Their ideal culture is closer to the clan, adhocracy and further from the market (compared to the average). The perceived current and the ideal culture are significantly different only in the adhocracy type. From the 20 items of the OCAI questionnaire 7 were significantly different from the average in the case of the perceived culture and 13 in the case of the ideal culture. Differences between ideal and present cultures are statistically supported only in the following dimensions: dominant characteristics (clan is currently stronger, adhocracy is weaker), corporate leadership (market is currently stronger), strategic emphasis (hierarchy is currently stronger).

What Drives Capital Financing in Europe? Evidence from Listed Firms in Germany
14-31Views:523This article analyzed the factors that affect the capital financing of German non-financial corporations listed on the German Stock Exchange from 2017 to 2021. By applying a panel data regression model and the Generalized Least Squares (GLS) approach, the results show that the debt-to-assets ratio, equity multiplier, and long-term debt ratio are significantly impacted negatively by profitability as determined by the assets return. Firm size is positively correlated with both the equity multiplier and the long-term debt ratio, suggesting that larger companies use more long-term debt. Growth has a significant positive impact on the equity multiplier and long-term debt ratio but has little influence on the debt-to-assets ratio. Long-term debt is unaffected by liquidity, although the debt-to-assets ratio and equity multiplier are adversely impacted. The GMM method is used during the robustness check, and the findings are consistent with the major GLS findings. These results highlight how important firm-specific factors are in influencing choices about financial structure. The results of this research may be used as a guide for companies operating in Europe and offer valuable information about how to optimize capital structures in various financial contexts. Policymakers could also use the results of this investigation as a reference for creating financial laws and regulations that facilitate non-financial enterprises' access to financing and effective capital allocation.

The Middle East perspective of Corporate Social Responsibility
282-291Views:523Corporate 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.

The Individual, Education or Work Environment Influences the Quality of Graduates’ Employment?
244-260Views:322In this paper I examine what has an effect on the quality of the graduated students’ employment. The quality is measured by the the discrepancy between the educational attainment of workers and the educational requirements of their job. On the base of this I can distinguish matching and overeducated workers. The latter category can be divided into two other groups, so called genuinely overeducated, who are not satisfied with their mismatch, and apparently overeducated, who are satisfied with their mismatch. Using multinomial logit model I try to identify those individual, educational and workplace’s characteristics that influence being matching, apparently, or genuinely overeducated using the database of students graduated in 2007 and 2009 in the University of Debrecen. I try to test those factors that were determined in the literature like mobility and commuting propensity, market rigidity, career mobility, job tenure.

Practical Application of Methods in Strategy-Based Analyzes
59-72Views:760Increasing environmental volatility is a growing challenge for companies and businesses. The speed of economic events is changing, and the risk of uncertainty is increasing, requiring business to take a new approach to strategic planning. In the design and forming of their strategy, both the factors of the external and internal environment and the analysis of their competitors can be based on well-chosen methods. We consider the review of these methods, their application in planning and educational practice. The aim of our work, in which we present the methods that underpin the strategy applied in both domestic and international practice. The analysis of the external environment illustrates the construction and applicability of an external factor analysis matrix based on traditional PEST analysis and the Porter's five-factor model. In the case of internal factor analysis matrix, we focus on the approach of method choice, and on the applicable methods, the importance of the resource-based approach, the analysis of key factors and the Porter value chain analysis matrix. The third pillar of the analysis that underpins the strategy is the matrix-based assessment of competitors. The applicability of the methods depends on the form of the enterprise, the field of activity and the nature of its activities, which is complicated by the emergence of new economic spheres (e.g.: sharing) and transformed power relations.

Numerical Model Analysis of Myring–Savonius wind turbines
180-185Views:417Nowadays the importance of renewable energy is growing, and the utilization of the low wind energy potential is getting crucial. There are turbines with low and high tip speed ratio. Turbines with low tip speed ratio such as the Savonius wind turbine can generate adequate amount of torque at low wind velocities. These types of turbines are also called drag machines. The geometry of the blade can greatly influence the efficiency of the device. With Computational Fluid Dynamics (CFD) method, several optimizations can be done before the production. In our paper the Savonius wind turbine blade geometry was based on the so-called Myring equation. The primary objective of this paper was to increase the power coefficient by modelling the effect of the wind on the turbine blade. For the sake of simplicity, a 2D cross-sectional area was investigated in the simulation with ANSYS CFX 19.1.

Applicability of Optimization Methods in the Design of Automotive Rubber Products
358-363Views:310Size, shape or topology optimization are widely used to fulfil the requirements in the design process of rubber products. In many cases, the shape of the product is very complex and comes into contact with other components during operation. It is commonly subjected to large deformation for which the rubber shows strongly nonlinear behaviour. For this complex problem analytical solution is not available, thus finite element method could be used in which the analysis running is a time consuming process. The object of my research is to compare the efficiency and computational cost of different optimization algorithms. This article focuses on the applicability of various optimization methods in the field of automotive rubber goods. Direct search optimization and surrogate model optimization methods will be introduced.

Examining Drone Logistics Solutions in Retail
48-61Views:368The possibilities of using drones in transportation will be determined by the capabilities of drone technology, legislation, various advocacy and trade unions, and the degree of general acceptance. Technology and infrastructure are given, customer habits and needs are favourable, and emissions generated by packets moving between two points are growing steadily. Despite these favourable conditions, the effects of drone use should be thoroughly reviewed. The environmental impacts of the project were analyzed by PEST analysis and the main influencing factors were studied using the Porter model. Concluding our results based on questionnaire surveys and feasibility examinations of fast food delivery, it can be said that a system based on drones can efficiently be operated and cost-effective using round trips, however, the legal issues and uncertainties that arise in the delivery of drone hippers remain a very significant hindering factor for a long time.

Sport Consumption, Fan Engagement, Sport Statistics – Post-specific Passing Characteristics in Football
Views:907Digitalization and the explosive development of technology have led to significant changes in football. Due to the increasing amount of data available through various sensors and other data collections, we can observe the rise of data-centric, analytical and statistically oriented thinking in football, which is also of interest to fans. Digitalisation is also closely linked to sports consumption, which is why we have seen significant changes in this area in recent years. The pandemic has further amplified the speed of digital transformation in the sports industry. One of the most important contents for sports organizations and their fans is the in-depth sports statistics and analysis that enhances the consumer experience. In our study, we examined the most common performance indicator in football, passing. Our goal was to examine the position-specific pass characteristics in detail, therefore we also examined different pass properties in our research. As a model for our analysis, I chose the premier league, which has the highest UEFA coefficient. The three rounds (rounds 30-32) of the championship season 2019/2020 have been recorded and analyzed in terms of passes. there was a significant difference between the average number of passes per game between defensive and offensive players (t=7,988, p<0.05). There is also a gradual decrease in the number of passes attempted per match and the accuracy of the pass in the examination of the middle positions when examining the positions in the depth of the pitch. For both pass accuracy and average pass count, the decreasing ranking corresponds to the position of positions on the pitch (order: 1, central defender 2, defensive midfielder 3, inside midfielder 4, attacking midfielder 5, striker). In the value indicator of the position for passes, offensive positions performed more effectively than defensive positions. The extreme positions also stand out among the attacking positions, where in the case of the position value per pass number, 23.3% of the total test was completed and 14% of the amount of the established position value indicators was provided by these posts. Overall, our study points to post-specific pass characteristics and, knowing this, we can state that the comparison of players' passing performance is relevant if the players are in the same or related positions.

What Drives The Diffusion of AI Recruitment Systems in Swiss HRM? The Importance of Technological Expertise, Innovative Climate, Competitive Pressure, Employees’ Expectations and Contextual Factors
42-84Views:759This study examines organizational, environmental, and contextual factors influencing the diffusion of artificial intelligence recruitment systems in human resources management within Swiss organizations. Based on a survey provided to 324 private and public Swiss HR professionals, it explores how some technology-organization-environment theoretical framework predictors' as well as innovative climate provided by organizations influence the three stages – evaluation, adoption, and routinization – of diffusion of this innovation. To do this, the following article is based on a PLS-SEM structural equation model. Its main findings are that technological expertise, innovative climate, competitive pressure, and expectations regarding future use of the tool by organizations working in the same field are directly linked to the spread of this type of AI tool. However, public-sector organizations are more reluctant about using this type of tool. This aversion can, however, be moderated by an innovative climate and the fact that the HR function plays an active part in an organization's strategic direction. This said, this article makes a significant contribution to the literature about the diffusion of emerging technologies in organizations.

Measuring the Dynamic Characteristics of Electric Motors
359-364Views:331In our previous publications [1, 2], we described our vehicle dynamics simulation program which was developed in MATLAB environment. We also discussed its use for optimizing the technical parameters of electric driven vehicles. We detailed the model and simulation of the series wound DC motor which is part of the program. Besides, we described the experimental procedure by which we can determine the electromagnetic characteristics of the motor from the input parameters of the simulation program. In the present publication we deal with the determination of the dynamic characteristics of the motor (the moment of inertia of the rotor, bearing and brush resistance torques) experimentally. Knowing the above mentioned electromagnetic and dynamic characteristics, we can carry out the simulation of the motor and the results of the simulation can be compared to the results of the test measurements.

Role of Lean and Agile Supply Chain Models for Pellet Fuel Technologies
119-130Views:349Business organisations constantly strive to improve their processes, both internal and external. Within the supply chain of a product, different strategies can be applied. This paper aims to answer the basic questions like what is the core of lean and agile SCM strategies, what are the differences of the two models, and how can they be combined. This paper examines further, which of these SCM models and what elements of them can be applied for wood pellet supply chains, also examining the possibility of their combination. The result of these examinations is, that even though fuel pellets can be considered as simple commodity and not a very innovative product, diversity in input characteristics, optimization of fuel pellet technology process variables and changes in output market qualities and quantities need sometimes agile, flexible answer from pellet fuel SCM. The basically lean character of pellet fuel technologies and SCM can further enhanced by implementing agile SCM model elements, as is the increased integration of suppliers into the supply chain.

Sustainability in Urban Waste Management: The Efficiency of Electric Waste Transport Vehicles
1-18Views:419This study evaluates the long-term economic feasibility of electric waste collection vehicles (EVs) as a sustainable alternative to diesel-powered counterparts in urban municipal services. Using real operational data from a Hungarian waste management company, we developed a total cost of ownership (TCO) model spanning 10 years, which incorporates investment costs, energy consumption, maintenance, depreciation, and battery replacement. Our analysis reveals that although EVs require a significantly higher upfront investment (€350,000 vs. €183,200), their lower operational and maintenance costs result in a break-even point around year 8. When accounting for a €50,000 battery replacement in year 6, the total 10-year cost of the EV remains lower (€431,769 vs. €450,914) than the diesel vehicle, resulting in a net saving of €19,145. The study emphasizes the significance of local energy prices and service structures in assessing fleet electrification. While the findings are based on Hungarian data, the proposed methodology can be adapted internationally to support data-driven decision-making in sustainable waste logistics.

How Does Public Debt Change when the Next Crisis Comes - and It Will Come!/the Expected Evolution of Greece's State Debt in the Next Crisis Period/
91-104Views:397It has recently been announced that Greece may withdraw from the Euro-Zone permanent rescue fund's aid program because it has successfully met the conditions imposed on it. Creditors and credit qualifiers also agreed that the Greek economy was on a good growth path. That is why there is a chance that by 2030 the current sovereign gross debt of 182.7 per cent of GDP will fall to 123.3 per cent. The author finds this statement unfoundedly optimistic. He argues that the Greek debt ratio – despite the current optimum economic fundamentals – does not seem to be sustainable. He sees greater probability that in the near future it will again be necessary to release some of the Greek debt. Debt reduction will also mean a new orderly state bankruptcy. The study seeks to highlight how vulnerable and risked the sustainability of current Greek debt financing. Using a macroeconomic model, it shows and justifies how the Greek sovereign debt changes in the case of a crisis that is only half the extent of the previous subprime crisis. If this happens, by 2023, the state debt will rise to more than double the national product, and by 2030 only to the present, otherwise critical, level. It follows that the high risk of financing Greek state debt remains unchanged.

Analysis of Social Media Activities - Through the Examination of Handball Clubs Competing at Different Levels
39-53Views:650In 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.

New Method for Dynamic Tribological Test of Engineering Polymers
25-29Views:281In this article, tribological tests of Polyamide 6 (PA 6), Ultra High Molecular Weight Polyethylene (UHMW PE) and Polyoxymethylene copolymer (POM C) by a new testing method is introduced. The tribometer used in the test is capable for pin-on-disc measuring within all possible layout known in tribology practice, otherwise can be modified into special model of fatigue sliding test. The pin was a specimen made from examined materials, always in contact with a rotating metal disc under a normal load, which is usually static. However, since vibration exists in every practical scene as an important phenomenon, for instance in turning process, we added vibration load into the test. The supplement load is generated by a special-designed vibrating machine. Then properties of examined materials can be studied more profoundly under vibration load. As a result, different value of friction coefficient in static and vibration load have been discovered and taken into comparison.
