A systematic literature review on green human resource management (GHRM): an organizational sustainability perspective

Gábor Szábo-Szentgróti Masum Miah Virág Walter

Publication Name: Cogent Business and Management

Publication Date: 2024-01-01

Volume: 11

Issue: 1

Page Range: Unknown

Description:

The purpose of this systematic literature review is to identify trends in Green HRM research related to sustainability over the past decade and to determine how green human research management (GHRM) research is related to sustainability, its antecedents, and the level of implementation. After analyzing keywords through the VOSviewer application, the results showed that green human resource management is an umbrella keyword, allowing the identification of related research areas such as environmental management and environmental sustainability. The results also showed that most (63%) of the selected articles were published in the last three years and most of the articles were published in Q1 journals. Furthermore, most articles used quantitative methodologies and were conducted in developing countries. It has also gained the highest interest in employees’ sustainable behavior and environmental sustainability, but there are few studies on social sustainability and economic performance. The study also found that the implementation level of GHRM in organizations is moderate, with very few studies in this aspect. The originality of this systematic review lies in examining the link between GHRM and corporate sustainability goals. This paper is limited to reviewing online sources using only academic articles from Scopus and Web of Science; other sources are ignored. It will help academics by providing future research directions for investigation. Top management can also better understand how GHRM helps organizations achieve sustainability goals.

Comparative study of the application of steels and aluminium in lightweight production of automotive parts

Imre Czinege Miklos Tisza

Publication Name: International Journal of Lightweight Materials and Manufacture

Publication Date: 2018-12-01

Volume: 1

Issue: 4

Page Range: 229-238

Description:

The automotive industry has a decisive role in the economy of developed countries. Sheet metal forming – as one of the main processes in car manufacturing – has similarly important role. Concerning the recent trends in car production, the application of lightweight constructions principles is the main priority to meet customers' demands and the increased legal requirements. To meet these expectations, the application of high strength materials is regarded as one of the most promising possibilities. Applying high strength materials – beside high strength steels like DP1000, TRIP780 recently aluminium alloys, e.g. AA7021 or AA7075 – have a positive response for many of the requirements: increasing strength results in the application of thinner sheets together with significant mass reduction, leading to lower consumption with increased environment protection; however it can often lead to the decrease of formability, too. In this paper, an introduction on recent material developments in the automotive industry concerning both the use of new generation high strength steels and light metals with particular emphasis on aluminium alloys will be given. A comparison between steel and aluminium application in the automotive industry is given from various points of view. Since our main topic is the sheet metal forming, in this paper the body-in-white manufacturing in the automotive industry is the primary focus field.

Demonstrating the Options for Automated Advanced Selective Waste Gathering

I. Lakatos Ádám Titrik Janos Hollosi

Publication Name: Sisy 2018 IEEE 16th International Symposium on Intelligent Systems and Informatics Proceedings

Publication Date: 2018-11-05

Volume: Unknown

Issue: Unknown

Page Range: 167-171

Description:

Due to continuous developments, the exhausting and unpleasant work done by humans is going to be partly or totally replaced by automated devices. Such developments can be found in the field of transport concerning autonomous and networked vehicles. Although we are at a quite early stage of development, it is highly practical to make plans for a more distant future, i.e. targeting a totally automated selective waste gathering. Apart from the application of smart containers, this study presents alternatives for networked automated selective waste gathering.

Evaluation of Bone Conduction and Active-Noise-Cancellation Headsets Based on Listening Tests in a Virtual Environment

Gyorgy Wersenyi

Publication Name: Infocommunications Journal

Publication Date: 2023-01-01

Volume: 15

Issue: 3

Page Range: 54-62

Description:

Alternative design headsets incorporating activenoise-cancellation or bone conduction were evaluated in listening tests in a virtual reality environment. Virtual sound sources in the horizontal plane had to be identified using stereo panning in the frontal hemisphere. In addition, transfer characteristics and damping effects were measured with a dummy-head. Results indicate that up to five source locations can be used in real applications with high accuracy in virtual scenarios, independent of the spectral content of the excitation signals. Furthermore, the use of noise cancellation in presence of 80 dB background noise does not improve performance. Commercially available bone conduction headsets can provide the same detection accuracy even if the subjective sound quality is lower.

‘Law Is Not Politics’: The Role of the Liberal View on Law in the Rise of “New Populism”

Mátyás Bencze

Publication Name: Law Populism and the Political in Central and Eastern Europe

Publication Date: 2023-01-01

Volume: Unknown

Issue: Unknown

Page Range: 166-183

Description:

While it is widely accepted that the recent democratic decline in Hungary can be traced back to many factors (e.g., political, social, economic, etc.), it may be worthwhile to focus on and analyse one of them in particular: the fact that the dominance of the liberal discourse on the law between 1990 and 2010 led to jurists, democratic politicians, and other intellectuals becoming exposed to the attacks of neo-authoritarian forces. In this chapter, I examine one of the characteristics of the liberal theory of law which facilitated the spread of a conviction among democratically thinking people with an interest in public affairs. This conviction is based on the assumption that there is a sharp boundary between law and politics, and following from that, that neutral legal institutions, by relying solely on the law, are able to defend the rights of the citizens against any political attack. Believing in this myth, democrats did not appreciate the true weight of the political nature of legal decision making, and the undemocratic forces were able to capitalise on their naïvety.

Optimum control strategy for PMSM in field-weakening region by constant power

Istvan Szenasy Zoltán Szeli Zoltan Varga

Publication Name: Electrical Systems for Aircraft Railway and Ship Propulsion Esars

Publication Date: 2015-05-04

Volume: 2015-May

Issue: Unknown

Page Range: Unknown

Description:

For electric vehicles an applied control of PMSM is the flux weakening operation for extending the region over nominal speed on nominal voltage. This paper deals with these questions and its impacts. Proved methods increase the torque angle and the d axis directed component of the stator current vector reduces the main flux, but the eddy current loss developing in magnets became significant. These impacts and their reduction need several investigations. This paper preents the possibilities and limits of flux-weakening for a given PMSM, and gives a usable optimum control strategy on nominal power's region by varied speeds.

Modeling Hepatitis B and Alcohol Effects on Liver Cirrhosis Progression

Haci Mehmet Baskonus Dragan Pamucar Nigar Ali Zeeshan Ali Imtiaz Ahmad Zia Ur Rahman Imtiaz Ahmad Naseer Ul Haq

Publication Name: CMES Computer Modeling in Engineering and Sciences

Publication Date: 2026-01-01

Volume: 146

Issue: 1

Page Range: Unknown

Description:

Hepatitis B Virus (HBV) infection and heavy alcohol consumption are the two primary pathogenic causes of liver cirrhosis. In this paper, we proposed a deterministic mathematical model and a logistic equation to investigate the dynamics of liver cirrhosis progression as well as to explain the implications of variations in alcohol consumption on chronic hepatitis B patients, respectively. The intricate interactions between liver cirrhosis, recovery, and treatment dynamics are captured by the model. This study aims to show that alcohol consumption by Hepatitis B-infected individuals accelerates liver cirrhosis progression while treatment of acutely infected individuals reduces it. We proved that a unique solution of the proposed model exists, which is positive and bounded. Using the next-generation matrix approach, two basic reproductive numbers RA0 and RAmax are calculated to identify future recurrence. The equilibrium points are calculated, and both equilibria are proved locally and globally asymptotically stable when R0 is below and above one, respectively. It is shown that bifurcation exists at R0 = 1 and a detailed proof for forward bifurcation is given. Furthermore, we performed the sensitivity analysis of the model parameters on R0. For the confirmation of analytical work, we performed numerical simulations, and the results indicate that the treatment and the inhibitory effects reduce the risk of developing liver cirrhosis in individuals, while heavy alcohol consumption accelerates markedly the liver cirrhosis progression in patients with chronic hepatitis B.

Detection of Bus Driver Mobile Phone Usage Using Kolmogorov-Arnold Networks

Áron Ballagi Szabolcs Fischer Janos Hollosi Gabor Kovacs Viktor Nagy

Publication Name: Computers

Publication Date: 2024-09-01

Volume: 13

Issue: 9

Page Range: Unknown

Description:

This research introduces a new approach for detecting mobile phone use by drivers, exploiting the capabilities of Kolmogorov-Arnold Networks (KAN) to improve road safety and comply with regulations prohibiting phone use while driving. To address the lack of available data for this specific task, a unique dataset was constructed consisting of images of bus drivers in two scenarios: driving without phone interaction and driving while on a phone call. This dataset provides the basis for the current research. Different KAN-based networks were developed for custom action recognition tailored to the nuanced task of identifying drivers holding phones. The system’s performance was evaluated against convolutional neural network-based solutions, and differences in accuracy and robustness were observed. The aim was to propose an appropriate solution for professional Driver Monitoring Systems (DMS) in research and development and to investigate the efficiency of KAN solutions for this specific sub-task. The implications of this work extend beyond enforcement, providing a foundational technology for automating monitoring and improving safety protocols in the commercial and public transport sectors. In conclusion, this study demonstrates the efficacy of KAN network layers in neural network designs for driver monitoring applications.
