Cím:A Blind Man Leads a Blind Man? Personalised Nutrition-Related Attitudes, Knowledge and Behaviours of Fitness Trainers in Hungary / Anna Kiss, Laura Pfeiffer, József Popp, Judit Oláh, Zoltán Lakner
Dátum:2020
ISSN:2072-6643
Megjegyzések:It is well-documented that fitness trainers could play an important role in the nutritionrelated behaviour of their clients based on their personalised nutrition-related counselling activities, but there are considerable concerns all over the world about the level of their knowledge to become nutritional coaches. In the framework of the current study based on qualitative (focus-group interviews) and quantitative (questionnaire and analysis of responses by multivariable methods, as well as structural equation modelling) methods, it has been proven that (1) theoretically, both the trainers and the dietitians acknowledge the importance of cooperation in the optimisation of coaching efficiency and advisory work due to some ?professional jealousness" and differences in professional background, as well as in culture, so it is hard to find a common platform for cooperation, especially in market segments characterised by relative low levels of purchasing power; (2) due to lack of regulation, there is a high heterogeneity of professional competences of trainers in general and their nutritional competences, in particular; (3) the majority of trainers do not have an objective picture on his/her effective nutritional knowledge, and they often offer a much wider scope of services (e.g., nutritional counselling for clients with chronic diseases) which are well beyond their professional knowledge and (4) the dietary guidelines have not become an integral part of professional knowledge, even at the level of specialists. To improve the current-in some cases, dangerous-situation, the following steps should be taken: (1) enhancement of the level of professional qualification of future trainers, integrating the practice-oriented approaches and emphasising the role of teamwork by simulation-based practices; (2) highlighting in a clear way the professional and ethical boundaries of the activities of trainers and (3) working out an efficient incentive system for the continuous professional development of trainers.

Cím:The reform of school catering in Hungary : anatomy of a health-education attempt / Anna Kiss, József Popp, Judit Oláh, Zoltán Lakner
Dátum:2019
ISSN:2072-6643
Megjegyzések:School lunch nutrition standards are an important carrier of messages on healthy eating and an efficient way of changing the nutritional behaviour of new generations. Many countries in Europe have a compulsory system of school meals; the Hungarian government also wanted to take action in order to improve the nutrition requirements of the school catering service. The Hungarian Ministry of Human Resources established some limits in the school catering system. However, increasing public pressure forced the legislating organ to considerably modify this regulation. The aim of this study is to analyse the causes of this failure, based on a conceptual framework of institutional economics and a strategic modelling of different institutes by examining the results of 72 interviews (33 experts, 26 parents and 13 teachers) conducted with representatives of different stakeholders. The results highlight the lack of preparation for the introduction of the new regulatory framework, as well as the inefficient communication between the different stakeholders. In order to support children in eating healthfully, a complex nutrition education program and continuous dialogue is needed between teachers, parents, catering staff and the government.

Cím:Towards understanding dietary supplement use among recreational athletes on the basis of a complex, multifactorial model / Anna Kiss, Judit Oláh, József Popp, Zoltán Lakner
Dátum:2020
ISSN:1336-8672 1338-4260
Megjegyzések:The possibilities for development in the food market are rather limited because the market is becoming saturated. At the same time, the changing values and lifestyle of consumers open new frontiers for development. A striking example of this is the case of dietary supplements (DS), functional foods. There is a mushrooming number of publications analysing the different causes and consequences of the increased use of DS, but we do not have an integral picture of the socio-economic forces behind this innovation success. The methodology of analysis used offers the possibility of a wide-range adaptation and application of a model. Based on a conceptual model of the system of factors that influences DS consumption, a closed-ended, anonymous survey was carried out with participation of 617 respondents (men 32 %, average age 26 years), in Hungary, as a result of which we have determined that 61 % of recreational athletes use at least one type of DS. There were no significant differences in terms of the socio-economic characteristic features of respondents. The role of factors influencing DS consumption was analysed through a structural equation model. Athletes engaging actively in recreational sports consider DS consumption per se as a precondition of an improvement in performance.

Cím:The structural change of the economy in the context of the bioeconomy / Lakner Zoltán, Oláh Judit, Popp József, Balázs Ervin
Dátum:2021
ISSN:2667-0410
Megjegyzések:The bioeconomy is a highly complex, cross-sectorial concept covering all sectors and systems that rely on biomass. Based on the analysis of the size of bioeconomy in the V4 countries it can be concluded that the sustainable transition is a great challenge and can be achieved by developing national circular bioeconomy strategies. It is extremely difficult to analyse the contribution of different sectors to the performance of the circular bioeconomy. Currently, the contribution of different sectors to the biomass-based economy is very complex, therefore a strate- gic socio-economic planning and optimal resource allocation is necessary to achieve the goals of the bioeconomy. This paper aims to determine the place and role of the bioeconomy in the structural change of the linear econ- omy, based on detailed matrices of in- and output relations between different sectors. Based on the input-output matrices, as well as centrality and flow metrics of network analysis, the role of the bioeconomy in the linear economy, its multiplicative effects and future research implications are analysed.

Cím:Building Coalitions for a Diversified and Sustainable Tourism : two Case Studies from Hungary / Lakner Zoltán, Kiss Anna, Merlet Ivan, Oláh Judit, Máté Domicián, Grabara Janusz, Popp József
Dátum:2018
ISSN:2071-1050
Megjegyzések:The development of the tourism sector has been a question of strategic importance for Hungary, a small, open economy with limited natural resources. At the same time, these efforts often generate considerable environmental conflicts, decreasing the sustainability of the environment. To understand the potential methods of sustainable tourism development, and to develop the optimal policy, it is essential to clarify the actors, their systems of interest and the potential ways of forging coalitions between them. The article presents an analysis of two case studies of rural tourism development: the "softening" of tourism at the most important touristic attraction in Hungary, Lake Balaton; and the conflicts arising from wine tourism development. Based on institutional economics, principle?agent theory and strategic management, and applying the MACTOR method, the authors identify the key actors, present the network of their mutual influences and goals, determine the most important conflicts and highlight the potential coalitions between them from the point of view of sustainable rural tourism development, as well as ways to further develop the regulatory environment. Based on this analysis, the article proves: (1) the importance of the modernization and re-organization of the public administration structure, focusing on optimal utilization of resources, as opposed to attaching to traditions; (2) the importance of forming clusters of different partners; (3) the strengthening of the knowledge base of decisions concerning sustainable tourism management; and (4) increasing conscious planning, based on the inclusion of different interest groups and long-term prognoses in local decision making, minimises the environmental burden of tourism.

Cím:National Culture and Financial Inclusion : evidence from Belt and Road Economies / Idrees Liaqat, Yongqiang Gao, Faheem Ur Rehman, Zoltán Lakner, Judit Oláh
Dátum:2022
ISSN:2071-1050
Megjegyzések:Financial Inclusion is a key factor in achieving the sustainable development goals of the United Nations. The research in the area of financial inclusion is becoming more critical for scholars and policymakers. In previous studies, effects of formal institutions on financial inclusion have been explored. However, influence of informal institutions (culture) on financial inclusion remained untapped. To fill this gap, we investigate how national culture affects the financial inclusion of 81 Belt and Road economies using 17 years of data from 2004 to 2020. The empirical findings of the two stage least square (2SLS) show that Hofstede's cultural dimensions are significantly associated with financial inclusion with different signs and levels of magnitude. We find that financial inclusion is lower in countries where uncertainty avoidance and power distance is high and that the opposite is true for individualism and masculinity. The overall results are reliable to a series of robustness checks and provide a useful basis for policymakers, regulatory agencies, and other stakeholders in achieving the sustainable development goal of financial inclusion in Belt and Road countries.

Cím:Food chemistry patents influence on productivity : a case study of a sectoral approach in various oecd countries / Máté D., Oláh J., Lakner Z., Popp J.
Dátum:2017
ISSN:2081-7452
Megjegyzések:he effects of Intellectual Property Rights (IPRs) is one of the economic mysteries of the current literature. However, at sectoral-level, it has still failed to provide any obvious empirical evidence regarding any direct link between patents and productivity. The chief contribution of this research paper is to provide empirical evidence on how chemistry patents relate to productivity growth in the case of a low-tech intensive industry (Food, Beverage and Tobacco). In order to support both the theoretical and empirical findings of the literature a dynamic regression model is tested and found a valid representation of the negative relationship between food chemistry patents granted and productivity growth in the long run. Subsequently, some conclusions and policy implications are suggested in order to support the enhanced productivity growth performance of these food industries, highlighting the importance of changes in current property protection systems

Cím:Analysis and comparison of economic and financial risk sources in SMEs of the Visegrad Group and Serbia / Judit Oláh, Sándor Kovács, Zuzana Virglerova, Zoltán Lakner, Maria Kovacova, József Popp
Dátum:2019
ISSN:2071-1050
Megjegyzések:Risk management is one of the most important internal process, not only in large companies but also in small and medium-sized enterprises (SMEs). To identify the source of risk can be crucial in all companies. The primary objective of this study is to analyze and compare the economic and financial risk sources in SMEs of the V4 (Visegrad Group: Czech Republic, Hungary, Poland and Slovakia) and Serbia, in the context of the business environment of the countries analyzed. To achieve this goal, a questionnaire-based survey was carried out involving 2110 SMEs from Hungary, Poland, Slovakia, the Czech Republic, and Serbia. The questionnaire included questions about the importance of risks and the concept of risk management in the company. To test the formulated hypotheses, the following statistical tools were used: contingency tables, a Z-value, and a general non-hierarchical log-linear model with three categorical variables and a continuous covariate. Finally, the differences among V4 countries and Serbia were identified. Serbia is more vulnerable to the financial risk sources studied than the V4 countries. The result of the research shows that insufficient profit is more hazardous compared to the other risk sources and all countries are more vulnerable in in this issue. The article concludes with a discussion and a comparison with previous international researches.

Cím:Inventory methods in order to minimize raw materials at the inventory level in the supply chain / Oláh Judit, Lakner Zoltán, Hollósi Dávid, Popp József
Dátum:2017
ISSN:1895-2038 1734-459X
Megjegyzések:Each international producing organization seeks to implement its processes more effectively to minimize its costs and to maximize its profit. The primary purpose is to keep their inventory value at the lowest possible rate to minimize costs. To this end, the investigated organization operates several processes. One of them is the so-called Vendor Managed Inventory [VMI], in which the supplier manages the inventory at the customer and the second is the consignment inventory processing, in which suppliers store goods at the customer location. The principal goal of this paper is to examine whether the application of these methods may result in cost-effective savings for the examined organization and if yes, to what extent.Methods: This research was carried out in the framework of a case study at a producing organization in Hungary. Theselected case is the producing organization located in the North-Great Plain Region in Hungary. Analyses wereperformed using the relevant data from the inventory reports exported by the SAP as provided by the enterprise. Theresearch was performed in the examined enterprise between 1st ? 14th July 2016.Results: The situation analysed in this study provides an opportunity to describe the bullwhip effect and to demonstrate the opportunities to reduce it. This study found that the investigated company could save considerable amounts on packaging materials. We examined six high-volume packaging materials to identify the amount of potential savings. The process is recommended for the company to maintain it in the future; moreover, to expand it in the circle of new suppliers as well. The other investigated method for the minimization of inventory levels was the consignment procurement process. It can be concluded that consignment procurement process is the best method to reduce the examined costs.Conclusion: This research revealed the current distribution-side supply chain management practice, pinpointed theshortcomings and the potential directions of development. The obtained results draw the attention of Hungarian andinternational enterprises to the importance of conscious supply chain management and the wide range of tools which are available for the development of supply chain efficiency, thereby achieving a higher level of customer service.

Cím:Az alapanyagkészlet csökkentésére irányuló folyamatok bemutatása az ellátási láncban / Oláh Judit, Balogh Péter, Lakner Zoltán, Popp József
Dátum:2016
ISSN:1587-8694 2063-4552
Megjegyzések:Minden termelő szervezet törekszik arra, hogy folyamatait minél gazdaságosabb módon végezze a kiadások csökkentése és a profit maximalizálása érdekében. Az egyik fő irány a kiadások csökkentése céljából a készletérték minél alacsonyabb szinten tartása. Ennek eléréséhez több folyamatot is működtet a vizsgált vállalat, nevezetesen az úgynevezett beszállítók által vezérelt raktárkészlet ellenőrzési folyamatot (Vendor Managed Inventory ?VMI), amikor a beszállító kezeli a vállalat készleteit és a konszignációs eljárást, ahol a beszállító kihelyezi a gyár területére a készletet. Ennek a két eljárásnak a bemutatása és elemzése a kutatásunk célja. Arra a kérdésre keresünk választ, hogy ezek alkalmazásával valóban csökken-e a készletben lekötött tőke a vizsgált vállalat számára, és ha igen, akkor milyen mértékben? További kérdés, hogy elégséges-e a készletben lekötött tőkecsökkentés szintje ahhoz, hogy ezeket a jövőben is alkalmazzák vagy újra bevezessék? A kutatást esettanulmány jelleggel valósítottuk meg az Észak-alföldi régióban található termelő vállalatnál figyelembe véve az információs technológiai rendszerek szerepét

Cím:Food security perspectives in Sub-Saharan Africa / József Popp, Judit Oláh, Anna Kiss, Zoltán Lakner
Dátum:2019
ISSN:1582-9146 2247-9104
Megjegyzések:The state of global food security has been considerably improved in the last decades; however, these achievements are attributable to the "green revolutions" in Latin-America and Asia. The food shortage has remained persistent in Sub-Saharan Africa, where the proliferation of undernourishment is nearly 30%. There are a large number of studies investigating different causes and aspects of the current crisis, or evaluating the future of the African agro-food sector based of one or a few particular aspects (e.g. climate change, population dynamics). Just a small number of attempts have been made to offer a holistic approach focusing on future development possibilities. The goals of the article are (1) to set up a conceptual system-dynamic model for agro-food development in Africa, (2) test this model on examples of two representative countries, namely Uganda and Nigeria, (3) based on expert surveys, define development scenarios for the agro-food sector in these two countries and (4) determine the key actions for the improvement of the present situation. The system dynamics simulations forecast a rather gloomy future for the agro-food sector: even the historically highest development rate of agricultural production of these two countries will not be enough to meet the rapidly increasing demand for food. Scenarios based on expert estimations predict long-range stagnation in Nigeria and just a moderate probability of improvement in Uganda. Radical improvement in the food security situation and prevention of imminent social catastrophe necessitate wide-ranging socio-economic reforms focusing on (1) decreasing fertility, (2) a general upgrading of health culture, (3) promotion of cooperatives and (4) enhanced attractiveness of the agro-food sector for a wide range of business investment opportunities.
