Description:

Import product diversification is a major parameter in international trade. Import diversification contributes to economic growth and affects the environment due to its impact on energy consumption. In this article, we investigate the impact of import product diversification along with income, oil prices, natural resources, population, and foreign direct investment on energy demand, covering a composite sample of 102 developing and 36 developed economies over the period from 1995 to 2020. We also assess the impact of import diversification on energy demand considering all sub-samples. We find a significant long-run cointegration between total energy demand and import diversification for both developed and developing countries, confirmed by Pedroni cointegration tests. We further denote that import diversification together with other independent variables is stationary after the first differences in LLC unit root tests. Contrary to traditional methods, we apply panel quantile regression and conclude that import diversification, GDP, oil prices, foreign direct investment, natural resources, and population share long-run integration with total energy consumption for both developed and developing countries. The Dumitrescu and Hurlin short-run causality test confirms the existence of pair-wise bidirectional causality between all independent variables including import diversification, GDP, oil prices, natural resources, foreign investment, and population with energy demand. Our empirics conclude with important policy implications for sustainability.

Page Range: 143-168

Description:

The remarkable social urban rehabilitation effort of the Gyor Municipality which has recently been implemented and is currently in progress led to the considerable development of Gyor-Újváros, not only in the renewal of the actual built environment but also in the social improvement of the inhabitants. In our study we will look at the Gyor urban development project in three dimensions. First we explore its feasibility. Why is it Újváros that needed rehabilitation? Strategic documents and relating statistics prove the choice feasible: it is the place where the most significant segregation can be found in Gyor that needed intervention. Secondly, we analyse the intervention of the urban development. What were the changes, how did they affect the built heritage and the social status of the inhabitants of the area? Based on the available documents and reports we can state that significant results were achieved both concerning the built heritage and social adjustment and development. In the framework of empiric research, we examine through comparative analysis the conditions before and after the rehabilitation taking into consideration two aspects (modification of hard infrastructure and the modification of the soft factors) and 7 allocated indicators (I.1. Number of flats, I2 Number of businesses, I3. Level of convenience, I4. Surface area of the flats, I5. Rent prices, I6. Applicants receiving regular support, I7. Applicant receiving temporary support). Data are available partly from the feasibility study and partly from the data services of the Gyor Municipality. Result show that regarding several factors, rehabilitation had a positive effect in the neighbourhood. As a result of the rehabilitation the built environment has gone through significant improvement in case of six blocks of flats. The number of businesses for rent has increased, the convenience level of flats has changed positively too, as all flats have all modern conveniences and in most cases the surface area has also risen, thus providing better housing. Parallel to this the social status of the inhabitants living in this area has also improved as both the regular and temporary applicant receiving support has dropped significantly. Due to rehabilitation the rents have tripled after renovation which can be put down to the significant rise in standards.

Development processes of regional centres in Central and Southeast Europe - From state socialism to dependent market economies

No authors available

Publication Name: DETUROPE

Publication Date: 2019-01-01

Volume: 11

Issue: 2

Page Range: 92-100

Description:

The background of the current research is that despite the existence of a vast amount of literature devoted to the study of post-socialist transition processes, there is a relative scarcity of international comparative analyses on Central and Southeast European metropolises. The research seeks to explore FDI-driven transformation and development processes in Central and Southeast European regional centres in the posttransition period. The geographical focus of the analysis is limited to Central and Southeast European postsocialist states, while the scale of the analysis targets the metropolitan and regional level. The present study provides a brief summary of the first phase of the research constituted by literature review.

Description:

Current 3D scanning and printing technologies offer not only state-of-the-art developments in the field of medical imaging and bio-engineering, but also cost and time effective solutions for surgical reconstruction procedures. Besides tissue engineering, where living cells are used, bio-compatible polymers or synthetic resin can be applied. The combination of 3D handheld scanning devices or volumetric imaging, (open-source) image processing packages, and 3D printers form a complete workflow chain that is capable of effective rapid prototyping of outer ear replicas. This paper reviews current possibilities and latest use cases for 3D-scanning, data processing and printing of outer ear replicas with a focus on low-cost solutions for rehabilitation engineering.

Nexus between climate change, agricultural output, fertilizer use, agriculture soil emissions: Novel implications in the context of environmental management

Description:

In evaluating the influence of greenhouse gases (GHGs) on climate change, the effectiveness of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) is intricately tied to their atmospheric turnover rates, which play a crucial role in their heat-trapping capacity. Understanding the dynamics of how these gases cycle through the atmosphere is essential for assessing their respective contributions to the greenhouse effect and, consequently, their impact on global warming and climate change. The prime objective of this research is to examine the role of climatic change, agriculture output, and fertilizer use on the agriculture soil's greenhouse gas emissions. In doing so, the present study has focused on the temperature of land, fertilizer consumption, crop and livestock production, and energy used in agriculture soils on the pollution level of agricultural soils. The study further delineates the intricate interdependencies between climate change factors and GHG emissions using novel econometric methodologies, specifically the PMG-ARDL, SC-ARDL, and Dumitrescu Hurlin Panel Causality frameworks. In doing so, we use a large panel dataset spanning 1990 to 2020. The estimations show that climate change, as measured by variations in terrestrial temperature, has a discernible and positive impact on GHG emissions over the short and long term. Energy consumption and livestock production positively correlate with GHG emissions, with the former having a more pronounced effect. The implications of fertilizer usage and overall crop yield become noticeably significant in the long term. It emphasizes the importance of using a diachronic perspective when assessing GHG emissions in the agricultural sector. It is also worth noting that agricultural land use appears to negatively impact GHG emissions, emphasizing the importance of implementing sustainable land management practices to mitigate adverse environmental consequences. The study also explores the causality between climate change, agricultural practices, and GHG emissions, revealing a bidirectional association between climatic change and soil emissions. Additionally, unidirectional causation is observed from fertilizer consumption and crop production to emissions, underscoring the importance of adopting sustainable agricultural practices to reduce emissions. The findings offer valuable insights for governments and researchers to create sustainability-related strategies for dealing with climate change issues, safeguarding natural resources, and ensuring a sustainable future for agriculture.

Description:

A simple beam element based modelling technique has been developed which makes possible to analyze frames made of I sections with column-rafter bolted end-plate connections, subject to 3D loads, compatible with the thin walled beam theory with 7DOF beam elements. The model previously developed by the same team for welded connections has been ex-tended with the addition of linear spring elements to model the bolts located at the upper and lower beam flange level. The spring stiffnesses are calculated based on the extension of the Eurocode component method and verified by simulations performed with FEA software Abaqus.
