The role of community currencies in strengthening of local identity

Eszter Szemerédi

Publication Name: Civil Szemle

Publication Date: 2020-01-01

Volume: 17

Issue: 2

Page Range: 37-58

Description:

What kind of role could complementary and community currencies play in the strengthening of community cohesion and territorial identity? How can these systems help to reshape and re-evaluate local identity? Through answering these questions the study seeks to prove, that a functioning local community currency system can enhance cohesion among the local community members and can contribute to the strengthening of territorial identity, consequently to the success of a region. The study provides a literature review and references some international studies related to the topic, it also reviews Hungarian examples, highlighting the Rigac, the community currency of Alsómocsolád. The author analyses the documentation of Hungarian complementary currencies and the results from a survey of Rigac users. The results indicate that a complementary currency can strengthen and mobilize the network of local actors through the values it represents (local identity, institutionalization of cooperation, empowerment of the local community, etc.). It can serve as a staple that unites community members. If the system is successful, it can reinforce the sense of belonging and the pride it brings in its members. Based on research findings the study considers the alsómocsoládi Rigac as the most successful Hungarian example of strengthening the local community and local identity through a community currency system.

Foreign direct investment in the republic of serbia: Correlation between foreign direct investments and the selected economic variables

Laszlo Vasa Aleksandra Angeloska

Publication Name: Journal of International Studies

Publication Date: 2020-01-01

Volume: 13

Issue: 1

Page Range: 170-183

Description:

Foreign Direct Investment (FDI) in the theory of economic thought is considered to be an important factor for country’s growth and development. By encouraging multinational corporations to invest, host countries hope to generate spillovers because FDI transfer intangible assets to the affiliate, which may then diffuse to local firms. Serbia is integrating into European economic space with a significant delay. Despite a thunderous decade of wars and ethnic tussle, late transition and financial crisis, Serbia has experienced significant FDI inflows in the last decade, mainly because of the improved policies attracting foreign investors. The aim of this paper is to analyze the correlation and significant degree to which the examined variables are associated with each other. The economic variables cover 12 years (2007-2018). The main focus is on those variables that are considerably influencing changes and impact on FDI in Serbia. The study uses SPSS to analyse the correlations among the selected eight socioeconomic variables. The examined variables are: industrial growth, unemployment rate, employment from age 15 to 65, foreign trade balance, FDI inflows, FDI outflows, GDP growth, and the share of value added products in the exports. For this analysis the data from the Statistical Office or the Republic of Serbia, the National Bank of Serbia and the Ministry of Finance has been used. There is a very weak correlation between FDI inflows and the unemployment rate. Also, our results suggest there is a very weak correlation between FDI inflows and increased GDP growth. The GDP growth has strong correlations with the industry growth, FDI inflow and FDI outflow.

Publication Name: International Journal of Reasoning-based Intelligent Systems

Publication Date: 2020-01-01

Volume: 12

Issue: 3

Page Range: 200-209

Description:

For colonoscopy images the main information is in the fine structure of the surface of the bowel or colorectal polyps, similarly to the case of combustion engine cylinder surface scans, where the grooving and wear can be detected from the fine pattern superposed to a cylinder curvature. In both cases appear outliers, colonoscopy images have many reflections, whereas the roughness scanners detect small dust particles as well as the micron scale vibrations from the environment. The method presented in this paper takes care of both the problems using histogram stretching together with a special type of filtering. Also, masks are introduced in order to control the effect of the operators. The effects of the processing steps on the structural entropy of the image is also studied, as structural entropies are used in characterisation of the images. By removing the background makes the structural entropies much smaller, and by suppressing the outliers the structural entropies increase.

Sustainable public spending through blockchain

Judit Glavanits

Publication Name: European Journal of Sustainable Development

Publication Date: 2020-01-01

Volume: 9

Issue: 4

Page Range: 317-327

Description:

Blockchain technology and its industrial use cases can be detected worldwide. It is time for the state to think about the blockchain as an opportunity to reduce costs and build trust in the public spending. The paper and the presentation give an overview on how the state can apply the distributed ledger technology (DLT) and blockchain technology in the public administration: there are several countries with best practices already, and even more are in the introduction phase of opening to Industry 4.0 in the public services as well. On the field of FinTech area the state has great responsibility to regulate (or at least define) the phenomena of cryptocurrencies, that is already in use for more than 10 years now without any responsible governmental acts. Within this topic the Central Bank Digital Currency projects are also discussed in the paper, which are supported by IMF, and declared as the next natural step forward on financial markets.

From vérszerződés 'blood oath' to vérciki 'bloody awkward': Cultural conceptualization of VÉR 'blood' in Hungarian

Judit Baranyiné Kóczy

Publication Name: Magyar Nyelvor

Publication Date: 2020-01-01

Volume: 144

Issue: 1

Page Range: 103-122

Description:

Historical, ethnographic, and theological studies witness the diversified symbolism and decisive cultural role of 'blood'. The paper explores the role of the body fluid concerned in conceptualization, from the point of view of cognitive-cultural linguistics. The aim is to unfold the metaphorical and metonymic domains of Hungarian vér 'blood' and the culture-specific factors of world view (beliefs and events) that determine the role of that body fluid in the cultural cognition of the Hungarian community, on the basis of relevant expressions found in standard handbooks and data of the Hungarian National corpus. such factors include death, kinship, human nature, vitality, emotion, intensity, and malediction. The paper depicts conceptualizations of 'blood' and its profiled features in the individual domains in a network.

Extended fuzzy signature based model for qualification of residential buildings

Adam Bukovics Gergő Fogarasi Ĺaszĺo T. Ḱoczy

Publication Name: Studies in Computational Intelligence

Publication Date: 2020-01-01

Volume: 819

Issue: Unknown

Page Range: 91-97

Description:

Residential buildings can be qualified and ranked based on many viewpoints. For the intervening decision-supporting survey of old residential buildings in the course of our former researches we have created a fuzzy signature based model which defines status evaluation and ranking of buildings on the basis of the condition of load-bearing structures and other building structures. We have extended and changed this model in a way so that it should take into account other viewpoints, too, which, in addition to the load bearing viewpoints strongly influence the manner of intervening. Since in addition to the importance of the given structure the relevance of the building structures of residential buildings are determined also by their quantities and other features, in our case it was necessary to determine relative and absolute relevance weights. We use a structure of fuzzy signature with variable aggregations, where the definition of aggregations is made by parameters, and the value of parameters are changing depending on the specific application, which follow the changes of relevance of given subtrees. The developed method is examined on the basis of a database for which we were used status evaluating expert reports relating to real stock of residential buildings.

Description:

Students in engineering education need tools to gain insight into the ever-increasing complexity of engineering problems and possible solutions in the 21st century (e.g. seeking the reasons for the recent bridge-collapse in Genova). One of these tools could be the utilization of mathematical knowledge and skills - but many engineering students are undermotivated in studying mathematics. Not only Comenius but our digital age also prefers visualization over textual comprehension, as the Net generation is visually literate. Newer interdisciplinary research findings in brain functions and brain maturation are worth to be integrated into the pedagogy of teaching mathematics to engineers. Methodologically, in order to improve the quality of teaching Mathematics in engineering education at a Hungarian university, both findings in brain-research as well as theories of adult learning have been analysed from the perspective of visualization. The other direction of the work was focused on different types of visualization in Mathematics (according to Guzman), particularly in textbooks for engineering students. Ten textbooks, (among them the newly developed „Mathematics 1” at the Széchenyi István University), available both in print and online in Hungary have been compared from visual aspects. The current Curriculum of the subject „Mathematics 1” has also been analyzed from visual aspects. Findings show the need for a wider variety of visualization. Systematically detailing all of the above-mentioned perspectives and findings of data-processing contribute to developing an up-to-date conceptual framework for improving the quality of teaching Mathematics in engineering education at a Hungarian university, and it might be useful for other universities as well.
