Description:

Research addressing the microfoundations of corporate social performance (CSP) in small and medium-sized enterprises (SMEs) remains sparse. This paper aims to investigate how SME managers' ethical ideology affects CSP and examines the mediating role of their CSR orientation (CSRO): economic, legal, ethical, and philanthropic. Data were collected from 239 SME managers in the United Kingdom via survey and analyzed using regression and structural equation modeling. Findings show that idealism positively affects CSP, with philanthropic CSRO partially mediating this relationship. It also positively impacts all CSRO types. Relativism does not influence CSP but positively relates to economic CSRO. This paper is the first to integrate idealism, relativism, multiple CSRO types, and CSP into a unified model, providing insights into their interactions. It expands knowledge of CSP's personal drivers and offers guidance for educators, policymakers, and managers seeking to foster CSP.

Comparative Assessment of Carbon Capture Processes from the Perspective of Selection Criteria

András Torma Judit Pécsinger Anett Bedő Géza Köteles

Publication Name: Chemical Engineering Transactions

Publication Date: 2025-01-01

Volume: 121

Issue: Unknown

Page Range: 121-126

Description:

The Paris Agreement of 2015 aims to keep the global average temperature increase below 2 °C above preindustrial levels and to limit warming to 1.5 °C if possible. The European Union has set ambitious targets (-55 % by 2030 and Net-Zero by 2050) to support the European Green Deal (EGD). To reach the goals by the deadlines, extensive pre- and post-source measures are necessary. This article focuses on post-source measures and seeks to identify, quantify, and evaluate the selection criteria of the applicability of carbon capture techniques. The specific energy demand (theoretical minimum work required to separate CO2 from a gaseous mixture) of a capture process can be derived from the first and second laws of thermodynamics. There are, however, other factors that can significantly influence the decision-making process for carbon capture from a given polluting source. The first criterion group is related to the 2nd law efficiency, i.e., the proportionality between theoretical minimum work and real energy demand that can be achieved in practice, while the second group covers the specific separation cost as a primary economic parameter. The research gives comprehensive insights into the different carbon capture methodologies and analyses their dependency on CO2 concentration, the presence of impurities, and operational conditions such as temperature and pressure. Based on the analysis outcomes, selection criteria are proposed to help match mature technologies (TRL 7–9) to specific gas compositions and industrial applications, primarily for process gases from power plants, chemical industries, and cement production, supporting more efficient and context-dependent implementation and the green transition.

Consumer Cost Perception and Its Role in Hydrogen Vehicle Adoption †

Nikolett Gyurián Nagy Nikolett Gyurián Nagy

Publication Name: Engineering Proceedings

Publication Date: 2025-01-01

Volume: 113

Issue: 1

Page Range: Unknown

Description:

The widespread adoption of hydrogen-powered vehicles as a sustainable mobility solution depends on several factors, among which consumer acceptance is particularly important. This study examined how cost perception, demographic characteristics, and environmental attitudes influence the intention to adopt hydrogen-powered vehicles. The quantitative study (n = 1330) was conducted using an online questionnaire in Hungary. The results were verified by linear regression conducted in three steps, depending on the set of dependent variables chosen. The results showed that while cost perception alone has a moderate effect on acceptance, environmental attitudes have a strong and significant explanatory power. Acceptance is not merely an economic decision, but a value-based one closely linked to individuals’ environmental worldviews. The results highlight that the acceptance of hydrogen-based mobility is primarily a value-based decision, and that strengthening environmental commitment is key to promoting it.

Volume: Unknown

Issue: Unknown

Page Range: 125-130

Description:

This paper presents a modular smart home system integrating ESP32 microcontrollers with Apple HomeKit ecosystem to address scalability and data retention challenges in residential IoT deployments. The proposed solution employs the HomeSpan library for HomeKit-Compatible accessories, enabling secure local communication while maintaining compatibility with Apple's Home application. The key scientific contribution lies in the hybrid architecture combining real-time HomeKit control with a dedicated REST API server featuring SSL encryption and API-key authentication for historical data collection. The system addresses Apple Home app's limitation of lacking data retention capabilities through automated 5-minute data transmission intervals to a secure MariaDB database. Performance evaluation demonstrates stable operation across multiple sensor types (DHT22, PIR motion sensors) and actuators with modular deployment flexibility. Comparative analysis shows improved data persistence and analytics capabilities over standard HomeKit implementations while maintaining the security benefits of local communication protocols. The implementation achieves practical IoT deployment suitable for residential environments with enhanced comfort, safety, and energy efficiency monitoring capabilities.

Issue: 2

Page Range: Unknown

Description:

This paper aims to offer an overview of the features in the existing state of research on blockchains in the circular economy. A total of 79 articles published up to 31 May 2022 have been extracted from Scopus and Web of Science. The research design has enabled us to identify what characterises the present state of research on the use of blockchains in the circular economy. It has also allowed us to obtain a new categorisation scheme of the research that has identified five themes and the contributions in each theme and has allowed us to highlight several research gaps. The review findings indicate that the literature revolved around five research themes, namely, the relationship between blockchains and Industry 4.0, the potential of blockchains for circular economy practices, the role of blockchains in energy management, the role of blockchains in waste management and the impact of blockchains on sustainability. This review suggests several future research opportunities and provides practical implications for researchers and practitioners. To the authors' best knowledge, this study represents one of the first attempts to investigate the interplay between blockchain technology and the circular economy.

Determining the Deformation Characteristics of Railway Ballast by Mathematical Modeling of Elastic Wave Propagation

Szabolcs Fischer Balázs Horváth Mykola Kurhan Dmytro Kurhan

Publication Name: Applied Mechanics

Publication Date: 2023-06-01

Volume: 4

Issue: 2

Page Range: 803-815

Description:

The article solves the problem of theoretically determining the deformable characteristics of railway ballast, considering its condition through mathematical modeling. Different tasks require mathematical models with different levels of detail of certain elements. After a certain limit, excessive detailing only worsens the quality of the model. Therefore, for many problems of the interaction between the track and the rolling stock, it is sufficient to describe the ballast as a homogeneous isotropic layer with a vertical elastic deformation. The elastic deformation of the ballast is formed by the deviation of individual elements; the ballast may have pollutants, the ballast may have places with different levels of compaction, etc. To be able to determine the general characteristics of the layer, a dynamic model of the stress–strain state of the system based on the dynamic problem of the theory of elasticity is applied. The reaction of the ballast to the dynamic load is modeled through the passage of elastic deformation waves. The given results can be applied in the models of the railway track in the other direction as initial data regarding the ballast layer.
