Comrades in theory, outsiders in practice: Cuban and Polish workers in the Kádár era in Hungary

Csaba Sándor Horváth Lőwi Ildikó Horváth Csaba Sándor

Publication Name: Labor History

Publication Date: 2025-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

This study examines the political, ethnic, and social dimensions of transnational guest worker migration to Hungary during the late Kádár era, with a focus on Cuban and Polish workers. The research explores whether an institutionalized form of exploitation ‒ resembling colonial oppression ‒ emerged under state socialism despite official ideological commitments to racial equality. It also considers whether the socialist rhetoric of international solidarity was compatible with the realities of ethnic hierarchy and exclusion. Drawing on international and domestic literature, archival documents, statistical data, press sources, and focus group interviews, the study employs a primarily qualitative methodology to analyze the lived experiences of guest workers. The findings suggest that a form of socialist-style colonial exploitation was reproduced, especially in the case of Cuban workers, and that a complex mix of latent ethnic bias and overt national stereotypes shaped efforts to integrate guest workers. Finally, the research identifies key patterns that influence the acceptance or rejection of culturally distinct labor migrants and examines the broader ideological and social contradictions that these dynamics reveal.

Modeling the Efficiency of Resource Consumption Management in Construction Under Sustainability Policy: Enriching the DSEM-ARIMA Model

Yuriy Bilan Pruethsan Sutthichaimethee Grzegorz Mentel Halyna Mishchuk Volodymyr Voloshyn Volodymyr Voloshyn

Publication Name: Sustainability Switzerland

Publication Date: 2024-12-01

Volume: 16

Issue: 24

Page Range: Unknown

Description:

The aim of this research is to study the influence of factors affecting the efficiency of resource consumption under the sustainability policy based on using the DSEM-ARIMA (Dyadic Structural Equation Modeling based on the Autoregressive Integrated Moving Average) model. The study is performed using the Thailand experience. The research findings indicate that continuous economic growth aligns with the country’s objectives, directly contributing to continuous social growth. This aligns with the country’s efficient planning. It demonstrates that the management aligns with the goal of achieving Thailand 5.0. Furthermore, considering the environmental aspect, it is found that economic and social growth directly impacts the ecological aspect due to the significant influence of resource consumption in the construction. The resource consumption in construction shows a growth rate increase of 264.59% (2043/2024), reaching 401.05 ktoe (2043), which exceeds the carrying capacity limit set at 250.25 ktoe, resulting in significant long-term environmental degradation. Additionally, considering the political aspect, it is found to have the greatest influence on the environment, exacerbating environmental damage beyond current levels. Therefore, the DSEM-ARIMA model establishes a new scenario policy, indicating that resource consumption in construction leads to environmental degradation reduced to 215.45 ktoe (2043), which does not exceed the carrying capacity. Thus, if this model is utilized, it can serve as a vital tool in formulating policies to steer the country’s growth toward Thailand 5.0 effectively.

Reconstruction Italian style: Restoration of the san domenico church and monastery, forli, Italy by gabrio funari

András Veöreös

Publication Name: Metszet

Publication Date: 2016-01-01

Volume: 2016

Issue: 5

Page Range: 26-29

Description:

The most important part of restoring old buildings could be described as giving a new function to historical heritage sites. Contemporary construction techniques might need to be applied in such a way as to resist compromising the original building's integrity. This leads to a problem of historical faithfulness best explained by the simple fact that a contemporary rendering system will not adhere to older lime washed walls. Here the clash between original use and technologies has been the motivating factor behind restoration, not the creation of a stand alone architectural statement.

Page Range: 529-533

Description:

Multi-purpose dams play a significant role in water resources management and flood protection by storing and releasing water for a sufficient water supply. Significantly, numerous dam failures are observed in multiple regions. Natural hazards related to dams include extreme floods, drought events, earthquakes, and geological conditions. There are also human-induced impacts, such as inadequate dam operation or maintenance. Numerous studies simulate potential natural extreme events to address the wide-ranging consequences encompassing loss of human life, economic losses, and environmental effects. In addition, international commissions and federal agencies recommend and apply a general framework for dam safety and risk assessment. The current study suggests and develops a flexible framework for multi-hazard indices and risk assessment for Darbandikhan Dam, Iraq, which was impacted by successive extreme climate events, besides a strong earthquake (M 7.3) that occurred on November 12, 2017. Consequently, the earthquake led to various impacts along the dam site, including horizontal and vertical displacement in some places. In addition, consecutive years of drought led to significant shortage inflows to the dam reservoir. The current study methodology focuses on developing a multi-hazard index and risk assessment framework for each potential extreme event and failure mode scenario associated with dam operation and safety. The information required for the particular framework is through integrating the observed with a global dataset based on Geographic Information System and Remote Sensing techniques. Nevertheless, using different tools and models in dataset processing provides the acquisition of the essential input data associated with each probable severe event. The outcomes of the suggested framework will show through multi-hazard maps the affected areas (hotspots) and propagation consequences besides the residual risk and system response for each scenario. In conclusion, developing a framework of multi-hazards risks associated with dam operation provides promising outcomes for risk assessment, warning response, and evacuation tasks based on hazard maps with different spatial and temporal resolutions. In addition, the framework can be used as an assistance tool for decision support systems, planning, and environmental protection associated with multi-purpose dam operation and safety.

Regularization and multi-level tools in the method of fundamental solutions

Csaba Gáspár

Publication Name: Lecture Notes in Computational Science and Engineering

Publication Date: 2015-01-01

Volume: 100

Issue: Unknown

Page Range: 145-162

Description:

The Method of Fundamental Solution is applied to potential problems. The source and collocation points are supposed to coincide and are located along the boundary. The singularities due to the singularity of the fundamental solution are avoided by several techniques (regularization and desingularization). Both the monopole and the dipole formulations are investigated. The resulting algebraic systems have advantageous properties provided that pure Dirichlet or pure Neumann boundary condition is prescribed. Otherwise, the original problem is converted to a sequence of pure Dirichlet and pure Neumann subproblems, the solutions of which converge rapidly to the solution of the original mixed problem. The iteration is embedded to a multi-level context in a natural way. Thus, the computational cost can be significantly reduced, and the problem of large and ill-conditioned matrices is also avoided.

A complete ranking principle for trapezoidal Hesitant fuzzy sets and its application in solving trapezoidal Hesitant fuzzy linear programming problems

Dragan Pamucar S. Jeevaraj Rakhi Bihari

Publication Name: Complex and Intelligent Systems

Publication Date: 2025-12-01

Volume: 11

Issue: 12

Page Range: Unknown

Description:

Decision-making is significant in economics, education, management, industries, and many real-life situations. Every decision-making problem does not have crisp parameters and restrictions, and may have uncertainties and qualitative information. Trapezoidal Hesitant fuzzy sets are highly beneficial for dealing with situations that are more uncertain and have some qualitative aspects. First, this paper introduces four score functions on the class of trapezoidal hesitant fuzzy elements, namely mean-position, right-spread, inference, and support position score function to define a complete ranking principle on trapezoidal hesitant fuzzy elements. Secondly, we propose a complete ranking principle on the class of trapezoidal Hesitant fuzzy sets by generalizing the four proposed score functions on the set of trapezoidal hesitant fuzzy elements. Thirdly, we extend our work to suggest another complete ranking principle on the new important sub-class of the trapezoidal Hesitant fuzzy set. Fourthly, we compare our proposed complete ranking principle with a few existing important ranking principles discussed in the trapezoidal Hesitant fuzzy sets (TrHFS) class. Further, we establish two new simplex algorithms on a special class of trapezoidal Hesitant fuzzy sets to solve fully Hesitant fuzzy linear programming problems (HFLPP). These new algorithms incorporate the proposed complete ranking principle on the trapezoidal Hesitant fuzzy set. Finally, we solve a few numerical examples of linear programming problems with fully Hesitant fuzzy information to show the applicability and potentiality of the proposed linear programming method. Complete ranking principle in the class of TrHFS and the use of complete ranking principle in solving a fully HFLPP is proposed for the first time in the literature.

Institutional Efficiency and Research Productivity in Transitional Higher Education Systems: Panel Evidence from Uzbekistan

Svitlana Bilan Behzod Tagaev Muborak Qayumova

Publication Name: European Journal of Interdisciplinary Studies

Publication Date: 2025-12-01

Volume: 17

Issue: 2

Page Range: 61-72

Description:

This study investigates the determinants of research productivity in Uzbekistan’s public universities using a balanced panel of 15 institutions over 2010–2023. The analysis integrates three complementary dimensions: human capital, institutional efficiency, and macroeconomic conditions to explain why research output varies markedly across universities during a period of rapid reforms. A fixed-effects instrumental-variable model is employed to control for unobserved institutional characteristics and potential endogeneity in spending efficiency and economic indicators. The results show that academic staff capacity is the strongest predictor of research productivity, while GDP growth also contributes positively by creating more stable conditions for long-term academic development. Education spending efficiency has a meaningful effect, suggesting that governance and internal management shape how resources translate into research outcomes. These findings underscore the need to strengthen faculty development, improve institutional accountability, and align higher education policy with national economic priorities.
