Improving audit functions of supreme audit institutions to promote sustainable development63-69Views:201
In this paper, we demonstrate and analyze the substance of the added value effect of a Supreme Audit Institution (SAI), focusing on sustainable development issues.We intend to answer such questions as: how could a SAI respond to global and local challenges and how it could help government to implement commitments towards sustainability. Finally, we trace a possible way to improve external audit functions both on the state level and at the International Organization of Supreme Audit Institutions (INTOSAI), by using some ideas from network theory.
Education, scientific-research and consulting work in agriculture of Serbia11-18Views:108
Serbia has small number of producers2 which have encircled production system (from primaryproduction to processing), which do business successful, introduce marketing strategy and production standards, registered their products' mark of origin, succeed to export on EU market, use internet or has its own internet domain, etc. For creation of such, competitive and modern agricultural producer, there is necessity for production specialization, any kind of cooperation and better organization. In same time, there is more space for bigger financial support of state, as expert and consultative support „created“ through strong partnership between public and private sector, i.e. tough and constructive cooperation of state and farmers sector, like as institutions of education, science, research and consultative work. In the paper was given review of number and territorial dispersion of educational institutions, current scientific-research work and consultative functions in agriculture in Serbia, than was pointed out main problems in their functioning and previous work and also proposed concrete suggestions for overcoming of existing limitations, as for modernization /reorganization of those institutions, in a way to be more useful for agricultural producers.
Krishna consciousness in Europe: The way farming communities became the focal points of marketing13-24Views:235
Krishna Consciousness is regarded as one of the most successful new religious movements in terms of marketing in the Western World. The aim of this research was to identify and analyze the marketing strategy the members of the Krishna-conscious community apply in Europe via content analyses, field research observations and in-depth interviews. The marketing mix of services marketing (7P) are often suggested to be applied by religious communities as well, however, this concept has boundaries due to the principles of the religions, which may not be altered for the sake of marketing. The research has shown that in Europe Krishna-conscious communities have overcome this problem by shifting the product from religion to a complex touristic product, which is realized in the form of farming communities, which have become an important rural tourist attraction in some countries. As the comparison of the websites of the different institutions has shown that rural and farming communities are the ones, which focus mainly on attracting people, who are not familiar with Krishna Consciousness yet, while the websites of the other institutions communicate mostly with devotees or people already interested in the religion or its certain aspect (cuisine, education), rural and farming communities were the institutions chosen to be analyzed more closely. The marketers of these tourist attractions are therefore free to make certain modifications in the marketing mix, as its focus is a tourist attraction, not the religion itself; while the transmission of knowledge about the religion happens in the touristic attractions only. Seven European farming communities of six different countries have participated in the research so far, which may be extended to further communities and continents on the future for a more thorough analysis.
The global financial crisis: Implications for capital to agribusiness59-62Views:112
The global economy has continued to experience lingering effects of the global financial crisis that began in 2007. Although attention was initially given to the liquidity crisis and survival of some the world’s largest corporations and institutions, the financial crisis is likely to have long-lasting implications for agribusiness. As the world slowly recovers from the crisis, another round of problems are emerging as governments and international institutions attempt to unwind the positions they took in an effort to prevent the global economic bubble from bursting. Perhaps the most problematic factor for businesses is access to capital in sufficient amounts and at affordable rates. Governments and institutions, particularly in the United States (U.S.) and the European Union, have increased their financial obligations as the result of activities taken to curtail the economic crisis. These financial obligations and the associated financial risks place pressure on financial markets and tend to restrain the availability of capital and increase the cost of capital for businesses. However, the U.S. agricultural credit market has not experienced problems to the same extent as general business (commercial and industrial) and real estate credit markets have. In general, U.S. farm businesses have a strong balance sheet, adequate repayment capacity, sufficient amount of assets to offer collateral for loans, and reasonable profits. Thus, U.S. farm businesses have had an ample supply of credit at relatively low interest rates.
The political economy of agri-environmental measures: An empirical assessment at the eu regional level71-82Views:138
The paper deals with the political and economic determinants of EU agri-environmental measures (AEMs) applied by 59 regional/country units, during the 2001-2004 period. Five different groups of determinants, spanning from positive and negative externalities, to political institutions, are highlighted and tested using an econometric model. Main results show that AEMs implementation is mostly affected by the strength of the farm lobby, and the demand for positive externalities. At the same time it emerges a prominent role played by political institutions. On the contrary, AEMs do not seem implemented by the willingness to address negative externalities.
MBA education at Debrecen University Faculty of Agricultural Economics and Rural Development79-86Views:206
Debrecen is the capital of the Great Hungarian Plain, the centre of many institutions, organizations and business companies just in the heart of Europe. It has provided an ideal setting for higher education since 1538. With this past of more than 450 years, the University of Debrecen is the oldest higher educational institution in continuous operation in Hungary based in the same city. Higher education in agriculture began in 1868, when the National Higher School of Agriculture was formed in Debrecen. The University of Debrecen has more than 26 000 students, and more than 1700 instructors teach at the University, which has 13 faculties, 2 independent institutions, 20 doctoral schools and offers the widest choice of higher education. This outstanding intellectual centre, with a vast research and development capacity, has a growing importance in the economic and social development, cultural progress of the region. It devotes special attention to serving the needs of a knowledge based society more efficiently, and it strives to become the knowledge centre of the region, which also preserves traditions and values.
The labour market position of people with disabilities and with a reduced work capacity after the change of regime89-97Views:117
The study aims at exploring, based on an overview of the professional literature, the economic, social and employment policy situation which characterised the period from the change of regime to 10 years thereafter and concerned people with disabilities and with a reduced work capacity, as well as, the institutions and instruments influencing the related labour market demand and supply. It discusses those initiatives too which aim at increasing the economic activities of the related disadvantaged group. The topicality of the study comes from the fact that in the past few years the government has put a number of stricter legislation into force to strengthen the labour market position of people with disabilities and with a reduced work capacity in Hungary. Notwithstanding, the affected group still has low economic activity. In its background there is partially the economic-social situation and approach which characterised the transition period, as well as, the weak efficiency of the rehabilitation system, which was forming that time.
The evolution of the Avacongress113Views:109
In the early 1990’s MBA educations started independently in Warsaw, Prague, and Debrecen. In the middle 1990’s a small network was estblished with the mentioned institutions, as well as supporters from different universities like Wageningen, Aberdeen, Cork, later Fayetteville fromArcansas (USA). In the beginning of the 21st century the network became bigger. That time did Kiev join the Network, and started negotiations with Moscow Paralell to extended network leading by Warsaw University we applied for a EU Leonardo grant. The proposal was to develop the teaching and learning materials in the programme to a common approved standard. In order to improve the quality of teaching a set of commonly approved, standardized teaching materials had been eveleoped: Handbooks fo rmodules taught within 7 courses of the MBA programs: Public Policy, Economics, Management, Marketing, Finance, Operational Methods and International Agribusiness. Handbooks and case studies had been put on Warsaw University’s website and are now accessible for teachers and students from all academic institutions participating in the project. Materials had been developed by teams of experts in specific fields from different Universities.The whole set of materials was prepared in English. Another product of the project is the quality assurance standards applied by all MBA programs and an accreditation procedurefor the International Board. That time formulated the name AGRIMBA which is official name of the International Network on Agribusiness and Commerce.
Education as a factor of awareness development of organic product consumers39-42Views:121
Organic agriculture provides good quality products, the development of sustainable agriculture, environmental protection and economic efficiency. To develop a habit of consuming organic food, as is case with all habits, it is necessary to educate the younger population, so that they can become accustomed to the fact that organic food is a source of both human health and a healthy environment. Therefore, educational institutions should initiate actions in order to develop awareness of the importance of healthy and safe food (especially fresh fruits and vegetables) among youth. This action has already been carried out in some countries.
Role of innovations and knowledge – infrastructure and institutions7-10Views:235
There is a well known saying: Research converts money into knowledge, innovation converts knowledge into money. The knowledge-based economy has four pillars: innovation, education, the economic and institutional regime, and information infrastructure. Transformation towards a knowledge-based economy will necessarily shift the proportion and growth of national income derived from knowledge-based industries, the percentage of the workforce employed in knowledge-based jobs and the ratio of firms using technology to innovate. Progress towards a knowledge-based economy will be driven by four elements: human capital development, knowledge generation and exploitation (R&D), knowledge infrastructure. Increased investment in these four areas will certainly have an impact. National experience, however, suggests that an incremental approach will not work. Nations that have achieved accelerated growth in outputs and capabilities have acted decisively, targeting investments in areas of strategic opportunity. The organizational and infrastructural improvement of research requires supranational cooperation and the promotion of the free movement of knowledge. Therefore, the EU decision on the establishment of the European Institute of Innovation and Technology (EIT), which ensures that the GDP proportion for research and development (R&D) shall achieve 3% stipulated by member states in the long run, is particularly welcome.
Impacts of the global financial and economic crisis on the agro-food industry and rural livelihoods in Serbia113-118Views:111
Sixty-five per cent of the Serbian land area is agricultural and 55% of the population is rural.Agriculture share of GDP is more than 10% and about 47% of the rural labour force deals with agriculture. The aim of this work is to analyse the impacts of the global financial and economic crisis on the Serbian agro-food sector and rural communities. Measures introduced, mainly by public institutions, for relieving the consequences of the crisis are presented and discussed. Easily accessible yet high quality data from the central Office of Statistics in Serbia and specialized literature have been used. Impacts have been assessed by analyzing and discussing the trends of many socio-economic indicators. The crisis has had general impacts on the Serbian economy (low GDP growth, unemployment increase, price volatility, purchasing power decrease, etc.). Due to the crisis growth in agricultural production has been very low (0.1% in 2009). Agro-food exports decreased dramatically in 2008. About 9000 agricultural jobs were lost in 2008 and 2009. Reduced exports and lower domestic demand impacted negatively on agricultural commodity prices and agricultural household incomes.Access to credit became more difficult especially for small producers. However, agriculture is still a very important safety net. Agricultural employment share has increased both for men and women. The importance of agriculture is even higher if we consider the “grey agricultural economy”. To mitigate the crisis effects, the Government provided subsidies to rural people and will adopt the National Strategic Plan and Programme for Rural Development. Nevertheless, public institutions - in partnership with private, civil society and international organisations - should improve rural producers’ access to market information and credits and foster investments in rural areas including non-agricultural ones and those aiming at improving physical capital.
The institutional determinants of bilateral Agricultural and food trade53-57Views:132
The paper investigates the effects of the institutional determinants on trade in agricultural and food products among the OECD countries using a gravity model approach. We focus on the impact of the quality of governance and the similarity of institutions in explaining variation in bilateral agricultural and food trade patterns. Results confirmed the separate effects for the institutional similarity and the institutional quality on trade patterns. The institutional similarity has positive and significant impact on trade in a similar institutional framework for agricultural, but less for food products. The institutional quality has significant positive impact on trade in both agricultural and food products for importing countries.
The problems of regional development in Montenegro85-88Views:104
Economic development is a continuous, stochastic process considering that development depends on a multitude of historical, political, economic, cultural, ethnic and other factors. In the process of development, each country puts effort into strengthening their manufacturing potential, increasing the competitiveness of their economy by modernizing technology, and raising the level of education, culture etc. Owing to the accentuated actions of these factors, and different social, economic and other circumstances, there has been emerging polarizations in regional development, urbanization and so on. Proof of a country’s level of economic development can be found in various indicators such as capital equipment; the share of manufacturing, agriculture, and foreign trade; the share of the private sector in total ownership; the development of financial institutions and capital markets; the development and stability of the legal system; the development of transport, telecommunication and other infrastructure; the realized standard of living; the development of democracy and human rights protection; preserved environment etc. Economies of developing countries, including Montenegro, are usually characterized by a low capital equipment and low labor productivity, expensive manufacturing and insufficient share of world trade, high import dependence, uncompetitiveness, high unemployment, undeveloped entrepreneurship, and an undeveloped financial institutions. Polarized countries in an economic and development sense, are therefore those which are unevenly developed, and are constantly faced with highly pronounced problems of disparity in regional development and demographic problems. Solving these problems is a long-term process and necessitates. The design of a regional policy that is more efficient than the previous ones, as well, as building a different procedure for fulfilling the adopted regional policies.
Network attributes’ evaluation by stakeholder groups concerned to the agri-food sector in Hungary55-58Views:142
As a consortium partner, University of Debrecen, Hungary, has been conducting a European four-year project with the acronym NetGrow financed within the Framework Program 7 under the auspices of the EU focusing on network behaviour of food SMEs and the performance of networks. The overall objective is to reveal more evidences and facts on innovation, learning, and networking in the food sector of the EU. Whithin the scope of the project, special attention was paid to reveal how network attributes were evaluated by the main four stakeholder groups of the food sector such as food SMEs, public bodies, research institutions, and network management organisations. The respondents differ in ranking the attributes, while but we got a clear order of attributes, of which the top five can be explicitly selected. Taking the next three ranks into consideration, the attributes behind them have clear meanings and they seem to be complementary for the top five. The stakeholder groups were significantly differ in scoring openmindedness and external relations, the importance of network rendered services, and the goals relevance of the network to the firms.
Development of the European Union’s environmental policy and its measures for climate protection – a reviewViews:295
The negative impacts of human activities on the environment and nature can be felt worldwide. Thus there is a growing focus on measurements that keep sustainability in mind. As one of the main pioneers of environmental protection and sustainability efforts, these aspects are more and more prevalent in the current environmental policy of the European Union (EU). In this review article, the development of the environmental policy of the EU is presented. After listing the main milestones, the role of the EU in the area of environmental protection, the frameworks built around the goals and the roles of the institutions are discussed. Then – with an international detour – the details of the Paris Agreement about climate change and the state of the 20/20/20 commitments are summarised. In the remaining parts of the article, the focus is on the climate protection goals of the EU for the next three decades, the expected future directions, and the agenda of the von der Leyen Commission concerning climate protection. An important step and tool for achieving the goals set until 2050 is to incorporate climate and environmental protection elements to the 2021-2027 budget of the EU. In order to achieve the expected effects, it is crucial to develop the right tools of the environmental policy, to form a widespread cooperation, to raise awareness, and incentivise and support the innovative solutions in the sustainability area.
Cross-sector analysis of the Hungarian sectors covered by the Effort Sharing Decision – Climate policy perspectives for the Hungarian agriculture within the 2021-2030 EU programming period17-24Views:167
Ever since 2012, the EU ETS (European Union’s Emission Trading Scheme), which is the EU’s climate policy was extended to include the ESD (Effort Sharing Decision) sectors’ (agriculture, transport, building) regulations. As its name implies, this mechanism is based off of shared interests and efforts, all in order to reach the climate goals. Therefore, analysing the agriculture sector from an environmental viewpoint requires the analysis of related sectors as well, since their performances will have an impact on determining the requirements to be met by the agriculture. Seeing that those primarily present in said sectors are not various firms, but people and public utility management institutions instead, the level of regulations draws from the economic state of the various countries in question (GDP per capita). Therefore, member states like ours did not receive difficult goals until 2020, due to our performance being lower than the average of the EU. However, during the program phase between 2021 and 2030, all nations are to lower their GHG (greenhouse gases) emission, and have to make developments to restrict GHG emission level growth within the ESD, which means we already have to estimate our future possibilities. During the analyses, we will see that analysing agriculture from an environmental viewpoint, without doing the same to their related sectors and their various related influences is impossible. The GHG emission goals determined by the EU have to be cleared by the agriculture sector, but the inputs from transport, waste management and building are required nonetheless.

The role of chamber system in development of agricommerce in Serbia79-82Views:94
This research is carried out in order to be determined the role of Chamber system in development of agricommerce along with successful preparation of Serbia for EU accession. On February 28, 1857 Prince Aleksandar Karaðorðeviæ signed the Decree, called THE CONSTITUTION OF THE TRADE. By this Decree, the first BusinessAssociation in Serbia was constituted. Under the Law on retail stores passed in June 1910, the first chambers were established. Those were the following:
• The Chamber of TRADE
• The Chamber of CRAFTS
• The Chamber of INDUSTRY
• The Chamber ofWORKERS
Today, in conditions of economic and social reforms and transfer toward market oriented economy, chambers in Serbia chose to reconsider their role, by using experiences of chambers in countries with developed market economy.The chamber strives to be organized as independent, business oriented and expert association of economic operators. The structure of economy, from the aspect of important economic indicators (total revenue, profit), shows dominant share of manufacturing andagro-industry, trade, financial and other services sectors, transport, telecommunication, and construction industries. By generating over 30% of GDP and employment, Belgrade plays vital role in the economy of the whole Serbia. That is an advantage, but also the responsibility to constantly stimulate faster development and higher living standards by inciting the positive changes in economic and overall environment.
International students in Hungarian higher education113-132Views:256
Overall, higher education in Hungary is popular with students from abroad, even if there are significant differences in terms of its structure. The ever-faster increase in the annual headcount of the international student body serves as proof to this statement. The expansion of the size of the body of international students is of special importance in higher education since in 2016 the Hungarian government set the objective of having 40,000 international students by 2023 (EMMI, 2016).
Numerous studies have been published on this topic, usually focusing on specific issues, including, for example, the countries from which we receive most of the students, the most popular majors, possible economic advantages due to the presence of a great number of international students, and how internationalization takes place in higher education in Hungary.
By means of processing data published by the Hungarian Educational Authority [Oktatási Hivatal], this paper aims to present the changes in the number of international students in Hungary over the past ten years. This also includes the discussion of the structure of these changes related to a variety of issues such as relations, types of institutions and their ownership, levels and types of programs, as well as gender proportions. However, even with this effort, the officially available statistics are suitable for presenting a properly detailed assessment of the situation only to a limited extent.

Transition economy and happiness the Czech Republic compared with the Netherlands in the 1990- 2004 period119-126Views:173
The paper deals with the subject Transition economy and happiness – a case study of the Czech Republic in a comparison with The Netherlands in the 1990- 2004 period. The paper addresses the following two questions: 1. How has the level of happiness changed since 1990 in the Czech Republic and in The Netherlands? 2. Are there differences with respect to variables that explain differences in happiness between both countries. It appears that. at the beginning of the 1990s of the last century, the Czechs were less happy than the Dutch and, that, people in the Czech Republic were less happy in 1999 than they were in 2004. Furthermore, Happiness in the Czech Republic is approaching the level of happiness in The Netherlands. In both countries happiness is positively affected by subjective health status, perceived freedom of choice over life, being married or living together and satisfaction with one’s financial situation and having trust in social institutions. But there are differences with respect to the impact of age, education and religion .
Financing and operating questions of sports facilities5-8Views:262
This paper tends to present financing and operating questions of sports facilities. Infrastructure is very important for the sport businesses. Sports facilities and sports institutions, infrastructure development, and their legal, financial, accounting conditionality can be defined by the investors and the government (subsidies, taxes, etc.). Financial questions and IT background of facility management can be crucial for the enterprises interested in operating sports businesses. The paper focuses on these kinds of aspects of facility management based on practical examples.
Using DEA to evaluate efficiency of higher education79-82Views:496
The aim of the higher education reform process both in Hungary and in the European countries is establishing a competitive, qualitative higher education with efficiently operating institutions. The question of efficiency needs increased attention not only because of the decline of the state support but also the rapid raise of the student mass. In the educationsystemit’snot easy to measurethe output of the services.The situation is more complicated if an organisation or a sector has multiple inputs and outputs. In this case a possible method of determining efficiency is Data Envelopment Analysis. In my paper I’d like to introduce this method and use it to compare the efficiency of higher education systems. urthermore I am examining whether their efficiency is influenced by the extent of the contribution of the state and the private sector or socio-economic factors like GDP per capita and education level of parents.
Structured commodity finance77-83Views:156
Over the past years, the financial stock market – providing the capital demand that is the result of stockpiling and the characteristic strong seasonality observed in the agricultural sector – has increasingly grown and become more “used” by market participants. Its size had reached an annual value of 200 billion HUF, of which agricultural products had received the largest proportion through the various market participants (producers, integrators, traders, feed producers, mills). In the meantime, this market had become part of the competition between the commercial banks that are the largest financers of the sector, due to which the financing credit institutions had undertaken increasing risk levels, with respect to both degree of financing and the VAT financing related to stockholding. The practice of commodity financing by banks display a rather varied picture at present. Considering the exceptional degree of fall in prices and the actions of companies totally disregarding business ethics in 2008, it seems necessary to reveal the full scope of risks inherent in commodity financing. The primary aim of such an exercise is to ensure the prudent operation of refinancing activities for commercial banks. The inherent risks in trade financing – as has been proven by the experiences of previous years – are not found primarily in the goods themselves, but rather at the actual storage facility and also emerge in relation to clients, as well as the inadequate and ineffective risk management of price volatility by the financers. Therefore, the establishment of banking risk management and risk prevention techniques, including the development of new financing procedures become indispensable, minimizing all types of risks that had emerged in previous years.
Empowerment of rural women farmers and food production in Rathnapura district in Sri Lanka: a household level analysis105-112Views:227
Women empowerment and gender equity are two significant aspects of the sustainable development of a country. As Sri Lanka is on the way towards sustainable development, this study was conducted to assess the situation of women farmers’ empowerment and food production in Rathnapura district of the country. A sample of 300 women farmers was randomly selected for the study, from two selected Divisional Secretariat (DS) of Rathnapura district. Data was collected from a field survey using a pre-tested, self-administered questionnaire survey from April to July 2019. Empowerment was analyzed using the empowerment framework used by RAHMAN AND NAOZORE in 2007 in the study of “Women Empowerment through Participation in Aquaculture” with necessary modifications. Data analysis was conducted using descriptive statistics, correlation analysis and multiple linear regression analysis. Results revealed that majority of the women farmers were middle aged, married and had children. Furthermore, most of them had education up to secondary level. While average family size was four, average farm size was 1.25 acres. They had around 16 years of farming experience. The average monthly income of them was 25,000.00 LKR whereas 20% of it was from agriculture. The main sources of empowerment of women farmers were the Agrarian Service Center (55%) followed by village organizations/societies (30%) and microfinance institutions (26%). Furthermore, women empowerment index was 0.65. It is a moderate level of empowerment. However, there were women farmers under three categories of empowerment levels: low empowerment (4.1%), medium empowerment (58.5%) and high empowerment (36.1%). Out of the socio-economic factors; age, education, family size, land size, number of training programs participated, monthly income, experience in agriculture and number of organizations participated, education and number of training programs attended had significant and positive effect for the empowerment. Accessibility of credit facilities and agricultural extension program participation showed that there was a considerable impact on food production rather than the cultivable land size and utilization of modern farming technologies for food production. Therefore, proving of timely important agricultural education and training programs, enhance awareness level of modern farming technology utilization, better micro finance programs and agricultural credit facilities will be able to enhance the empowerment level of the women farmers of this area furthermore.

Examination of leisure sports alternatives provided by higher education institutions33-37Views:150
It is one of the main duties of sports in higher education to provide health conscious and sports-loving managers to the society. University years are a good opportunity to do sports in an organised framework, as well as lifestyle consultancy and to make use of the preventive function of sports. In this environment, the approach of students can still be shaped within a formal framework and their level of interest towards sports can still be increased. Furthermore, they can be motivated and become committed to sports if they have positive experiences. The aim of my analysis is to explore and describe the characteristics, peculiarities and current situation of higher education leisure sports. In this study, I present the results of the analysis of data collected with the first eight questions of the situation assessment part of the questionnaire survey. More specifically, I examined the evaluation of leisure sports activities, free sports opportunities and the branches of sports in which these are provided. I was also looking to find out where these sports opportunities are available for students inside or outside the institution and who they are organised and managed by. At the same time, I examined sports opportunities whose costs are paid by the student and analysed which branches of sports are available. Based on my results, I concluded that the sports opportunities of students are especially good according to the managers. This statement confronts the research findings which suggest that the sports activity of students is very low.
