    Performance evaluation is not only important in employer and employee relationships, but also in partnerships between a supply chain’s members. In order to satisfy customers’ needs according to the 7 Rights of logistics, all members of the given chain have to perform properly. To ensure the best performance, supplier evaluation can act as a starting point. Besides continous feedback, supplier evaluation plays an important role in performance development of suppliers. The aim of our research is to develop and introduce innovative supplier evaluation models, which include the advantages of traditional and electronic supplier evaluation forms. In addition to this, these models are visualised, making it easier to understand expectations and information. In this study, the aim is to present two different models the PaTeNt©- SESC (Pató Tetrahedrons of interNational Theory - Supplier Evaluation of Supply Chain) and the Douple Evaluation Platform, based on previous research.

    In the last decades there was a change in the field of corporate performance evaluation. Performance management systems, indicator-based systems and new, intellectual capital-based evaluation systems have appeared. Finally new, wide range of corporate evaluating methods was born in theory and in practice too. It is also important to mention, that in a life of organizations there is an improvement in the activity in connection with sustainable development, and also in the usage of methods connecting to sustainable development. Therefore the evaluation in the dimensions of sustainability – in a case of environmental performance evaluation, or evaluation of corporate social responsibility – became more and more emphasised. We concentrate on the theory and practice of environmental performance evaluation. Summarize – based on definitions – the concept of environmental performance evaluation. We concentrate on peculiarities of environmental performance indicators – based on international standards and literature review; and also mention the characteristics of indicator systems. Based on theory, the practice is also important. Therefore we present a case study of a multinational company.

    The research based on the trainee program of a large Hungarian company. The company recommends the program to entrants or those who have 1-1,5 years of work experience. The main objective is the evaluation of the effectiveness of the program through some of the HR functions. This study contains the process of the selection and the evaluation of getting into the program. What makes the program special, is the appearance of the technical mentor. According to the hypothesis, the mentor’s assistance reduces the uncertainty when the trainee inducted into the organization. The occasions of the beginner education, the conversations and feedbacks during the induction adds more efficiency to the success of the program. The searched data in literature features HR functions and mentoring. To learn about the program, a case study was made beforehand, and then the questionnaire was edited for the trainees at the company. In the course of the research, an interview was done with the technical mentor. The interview was based on the questionnaire. In point of the results, recommendations were defined connected to the assumed shortages of the program, also to increase the efficiency of the selection and induction. In conclusion, the maintenance of the trainee program is equally beneficial for the trainees and for the company as well.

    Student evaluation of faculty members is a current topic both internationally and in Hungary, partly due to the massification and partly due to the marketization of higher education. One of the evaluation methods is the internet-based voluntary rating which was started by ratemyprofessors.com in the U.S.A. and whose Hungarian counterpart is markmyprofessor.com. Research studies on the U.S. website – among many other critics – established that reliability of this evaluation method highly depends on the frequency of ratings: if an individual tutor is evaluated by more students, then the standard deviation of the ratings is smaller. The previous conclusion about the U.S. website is tested in our study based on Hungarian data. Our main result is that many of the experiences about markmyprofessor.com echo the previous findings about ratemyprofessors.com. Beside this in the Hungarian sample the higher response rate is associated with lower average ratings.

    Today, more and more articles have emerged in the field of sustainability and sustainable development. Sustainability plays an important role in supply chain management too. Green Supply Chain Management (GSCM) has emerged as a key approach for enterprises seeking to make their businesses environmentally sustainable. The notion of GSCM implies the insertion of environmental criteria within the decision-making context of the traditional supply chain management. Enterprises are increasingly expected to extend their sustainability efforts beyond their own operations to their suppliers and customers to their sustainability expectations. Literature of green supplier evaluation and selection methods number is large, though the number of environmental factors are relatively limited. Recently in supply chain management decision making, approaches for evaluating green supplier performance have used both qualitative and quantitative environmental data. Given this evolving research area, the purpose of this article is to analyse research conducted in international scientific journals focusing on the selection and evaluation of a green supplier. The purpose of this article will answered two questions: Which selection methods are commonly used? What environmental and other selection criteria for green supplier management are popular?

    The aim of the research is to do a statistical evaluation of agricultural and rural development engineer student’s motivation and personal competency. It sums up the late generation Y’s characteristics and challenges. To be a successful, graduated employee, not only the skill is needed but the personal competency as well. Altogether, 121 filled out questionnaires were collected from the students which were the prime source of the research. They had to evaluate influential factors to their motivation level and competence. The database was analyzed with descriptive statistic methods, principal component and cluster analysis. Studying the personal competency, five different factors were divided based on Belbin’s team roles and four clusters. The four clusters were established by the five factors. Analyzing the student’s educational motivation four different components were divided: the need of performance, social entertainment, the benefits of learning in the near future and the reach of the financial freedom. Based on the four components, generating clusters was not possible due to the significance level of the K-means cluster analysis because it was higher than 0,05 in every grouping variables.

    Lean and agile methods are now widely used in various fields. Seeing their success, management consultancy firms also want to take advantage of using them. In this case study, the company selects the appropriate task management tool for their operation, the kanban board, and implements it. The implementation process is supported by quantitative analysis. In order to track the introduction progress of the kanban board, a key performance index is defined: the board activity, which is the number of operations performed on the board in a given time period. Based on the evaluation of over 26 weeks’ data, board activity proved to be an appropriate indicator of the kanban board’s reception, operation, and stability. The individual indicators examined, however, were not found to be suitable for performance appraisal.

    The Dunning-Kruger effect (DKE) in higher education evaluation is one of the current research areas of psychology, educational science, and management science (in our case). Its importance is that the less prepared one is, the less accurately one can judge what performance is expected of him. What is more, he will err more and will overestimate himself. The present study aims better to understand the phenomenon with new, small-sample empirical results. The study is part of a research series that has been ongoing at the University of Debrecen since 2015. It not only quantitatively expands the literature but also includes the course of Knowledge Management among those examined. During the research, students were asked both before the examination (N = 63) and after the examination (N = 76) to guess how many points they would achieve on a multiple-choice test. It supports the presence of DKE, both in the case of pre-examination and post-examination self-evaluations. Using four multivariate linear regression models, we examined whether the sign value or absolute value of the errors made during the guesses show a correlation - in addition to the available control variables - with the test score. Our results showed that the more accurate the pre-examination and post-examination estimations were, the higher the students' actual score was, while the less they tended to overestimate their preparation. This supports the presence of DKE, both in the case of pre-exam and post-exam self-evaluation.

    Every spring the Hungarian Central Statistical Office records through its ELEKTRA database system the human and economic related operation data of the past year of civic organizations. This data source is usually considered as a standard at the evaluation of the domestic civic sphere. Still, the available handout titled “Most important features of the non-profit sector”, applying mainly descriptive statistics only provides a brief picture of specifications of the sector. Parallel with it, its background database is available yearly, which provides a unique possibility for a researcher to perform secondary analysis aiming to reveal deeper relationship. The objective of our study is purely to reveal a minor part of this considerable field, the relationship between subsidies and human resources mainly due to the fact, that human resource in this sector is composed of employees and volunteers, and it is questionable whether subsidies have an impact on employment.  Results revealed that there is a relationship between human resources and subsidies, where mainly private nature subsidies have a strong impact equally on voluntariness and work related employment

    Corporate 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.

  • Investigation on Double Oxide Film Initiated Pore Formation in Aluminum Casting Alloys

    The most common, and in fact, the most deleterious defects of aluminum casting alloys are the so-called double oxide films or bifilms, which have a central role in porosity formation, as they can easily unfurl and inflate into pores during the solidification of the alloys. Sr addition is generally used in the foundry industry for the modification of the eutectic Si phase of hypoeutectic Al-Si alloys. However, Sr microalloying usually leads to an increased pore formation tendency. As bifilms are preferred sites for pore formation, it should be expected that Sr additions have a significant effect on the number and/or the structure of double oxide films present in the melt. In this work, the relationship between Sr-concentration and the susceptibility to pore formation has been investigated through the evaluation of melt quality of melts which had different levels of Sr. The bifilm content of the melts was investigated by the analysis of K-mold specimens and X-ray computed tomography (CT) of reduced pressure test (RPT) samples. It was found that liquid alloys with a higher Sr concentration had a significantly greater tendency to pore formation, which can be explained by the presence of a larger number of bifilm defects in the liquid alloy.

    The agricultural planning often the question arises, how the different input (fertilizer, feed, irrigation, etc) from what to use on a production (land, animals) unit basis, and to what intensity. The input transformational efficiency experiments by setting analysis and evaluation. For example examined the nutrient replenishers fertilization experiments, the effect of nutritional values of the feed on the body weight gain, milk production in animal experiments. The input input efficiency to the external environment (weather, soil conditions, unexpected events), the technology used and the biological factors both influence. The farmer must be chosen in each sector, taking into account the magnitude of these inputs and environmental requirements. The economic optimum is usually trying to approach the sectoral level, which serves as the basis for future planning data. The mathematical programming models using relatively simply and quickly determine the optimal production structure. The models provide the specific resource requirements for, and the limitations of the objective function coefficients are calculated on the basis of sectoral. This becomes a deterministic model, and we can get the appropriate sectoral analyzes outstanding results of production structures. Therefore the relationships within sectors directly incorporate mathematical programming model and corporate interests placed above the interests of the industry to determine the intensity of the sectoral inputs. in their article a fertiliser application example, we present the production structure and the plant production sector fertiliser input of a time optimization, in which the fertilizer for specified sectoral relationships appear in the model objective function.

    The 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.

    In our study, we analyse various researches dealing with quality aspects of sport services, and different quality models related to the interpretation of quality. The results which were obtained in the framework of primary research activity present the opinions of students from five different research universities. Sport services’ operation and sustainability are determined by market regulations, as parts of the service industry. Considering that the university leisure sports services take place in a competitive environment, the universities often have to compete with external sports service providers for achieving confidence of the young generations. For the qualitative tests, we used the QSport-14 measurement scale, which is generally applied by sports centres. This scale investigates the sports services according to three different aspects: (1) instructors, (2) infrastructural facilities and equipment and (3) offered sport programs. We have adapted the measurement scale to the university environment because of the differences and special characteristics of external sports service providers and university sports services. In addition, we analysed the factors influencing recreational sports, and we also examined that what changes would be needed in order to improve the quality of recreational sport activities in higher education.

    The 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.

    This 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.

    Annual accounting statements are an important source of information within business relations amongst companies. However, it should be noted that due to their aggregate nature, the necessary information and through that the necessary knowledge 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 contributes to the more comprehensive interpretation of the other part of the annual statement. Beyond that, the notes to the financial statement have to help the presentation of a reliable and realistic overall image. In the notes to the financial statement, depth and detail of the disclosed information are not specifically stated, therefore their professional evaluation is left to the given enterprise. My basic purpose is to illustrate a comparison of the information content of the notes on the accounts between information technology services and sports activities. By means of text mining, we analyse the extent to which the notes on the accounts are in conformity with the Accounting Act.

    During 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) .
