Description:

Corporate governance is a major topic of debate among scholars from different parts of the world, but little has been empirically investigated on the impact of corporate governance on the discretionary work behaviour of employees in selected deposit money banks in Nigeria. Therefore, the purpose of this study is to examine the impact of corporate governance on the organizational citizenship behaviour of employees in deposit money banks. A cross-sectional survey design was used, which supports the use of questionnaire to collect data from the participants. Data were collected from 224 participants from 18 deposit money banks operating in south-east Nigeria. The study employed frequency distribution and linear regression to analyse respondents’ profiles and research hypotheses. Results of the study revealed that corporate governance dimensions predicted organisational citizenship behaviour indicators. The practical significance of this study lies in the possibility of improving organizational citizenship behaviour in organizations by integrating the main recommendations of this study into the corporate governance of organizations. This study concludes that corporate governance (measured in terms of leadership quality, accountability, board size, board effectiveness, and board independence) influences and improves organizational citizenship behaviour that is driven by altruism, integrity, sportsmanship, courtesy, and civic virtue.

Page Range: Unknown

Description:

Model observability is essential for the design of state estimators and observers, since the state vector can only be fully reconstructed from the measurements, if the model is observable. However, some research articles do not perform observability analysis and use unobservable models, while the presented results show adequate estimation performance. This paper deals with the impact of observability on the position sensorless state estimation of nonsalient-pole permanent magnet synchronous machine (PMSM). To show how the observability depends on the chosen coordinate system, observability studies are presented for two widely used nonlinear state-space models given in either the stator or the rotor reference frame. For the stationary reference frame model, a necessary and sufficient observability condition is defined, and it is shown that the model using rotor-oriented variables is unobservable. To point out the limitations of using the unobservable model, comparative simulations are carried out between extended Kalman filters using the models presented.

Page Range: Unknown

Description:

Advanced Driver Assistance Systems (ADASs) can have a significant role in contributing to road safety. However, technological innovations are gaining user acceptance at different rates, which is a key factor for their widespread deployment. In Hungary, learning about ADASs is not part of the curriculum in driving schools. In the present research, a questionnaire survey was conducted among driving examiners to assess their level of ADAS awareness. The results show that, in general, examining officers have a positive attitude towards the technology and are quite knowledgeable about it, compared to drivers. However, education and information are also essential for them, as there are few places to obtain credible information.

Examining Tertiary Education Amid the War in Ukraine: A Synthetic Control Approach

Marianna Kichurchak Olha Hrynkevych Halyna Mishchuk Yuriy Bilan Iryna Paslavska

Publication Name: European Journal of Interdisciplinary Studies

Publication Date: 2024-01-01

Volume: 16

Issue: 2

Page Range: 95-115

Description:

War consistently imposes significant challenges to the functioning and advancement of higher education. To identify the key trends in the development of tertiary education in Ukraine during 2014-2021 amid the war, the synthetic control method (SCM) was employed. The outcome variable for assessing tertiary education development is the gross enrolment ratio of the relevant age group. The broadest set of predictors influencing the dependent variable, for which statistical data is available on the World Bank website, consists of eighteen indicators. Through statistical and expert analysis, sixteen countries were selected for inclusion in the control group. The pre-war period was defined as 2000-2013, with 2014 marking the war’s onset, and 2015-2021 representing the war years. In the first stage, a synthetic model is constructed using the broadest possible dataset. In the second stage, the model’s sensitivity is analyzed, leading to the reduction of predictors to thirteen and the control group to ten countries. Consequently, the adequate synthetic model for the development of tertiary education in Ukraine from 2014 to 2021 was established. A placebo test confirmed that the observed gap between actual and synthetic values for tertiary education in Ukraine is not coincidental. The SCM analysis revealed that, without the war, a decline in demand in tertiary education would have been predicted for the 2014-2021 period. The observed gap underscores the significant impact of the war on Ukraine’s higher education system, providing valuable insights for shaping policy initiatives aimed at advancing tertiary education in the post-war era.

Description:

Lifelong learning is a basic requirement, in all areas in our rapidly changing world. One of the most important pillars of lifelong learning, is the teaching of learning by transferring basic knowledge of learning methodology, developing learning and thinking skills, through “self-knowledge discoveries”, that are associated with learning and by developing self-regulated learning. In this process, an important role is played by those methods, techniques and digital applications, that result in effective and successful learning, by adjusting to the learning style, habits and strategies of students.

Page Range: 949-954

Description:

Complex adaptation strategies concerning nutrition, housing technology, and veterinary treatment are required to maintain current production levels under increasingly stringent regulations on the preventive application of antibiotics. The reduced application of antibiotics is recommended for the sustainability of industrial pig production. Probiotic supplementation may contribute to improved sow and piglet health, mitigating the need for antibiotics. The effects of probiotic supplementation on sow performance and the quantity of fecal bacterial communities in lactating sows were investigated. Experimental sows received probiotic supplementation (n=10) and were compared to control sows (n=10). Fecal samples were collected from 20 sows in the second week of lactation. The quantitative measurement of total bacteria, Prevotella genus, Lactobacillus spp., and Bifidobacterium spp. was done by qPCR. Differences in backfat thickness (BFT), BFT loss, and feed intake of control and experimental sows were not significant (p>0.05). The amount of total bacteria, Prevotella, and Lactobacillus spp. was lower (p<0.05) in the fecal samples of experimental sows. The Prevotella percentage in total bacteria decreased, whereas Bifidobacterium spp. the ratio increased in experimental supplemented sows. Overall, probiotic supplementation resulted in notable alterations regarding some of the analyzed bacterial communities.

Description:

The technological development and the rise of artificial intelligence are driving a significant transformation of the labor market. The technological unemployment predicted by Keynes poses challenges for the global labor market that require new solutions. Basic income research has become a significant field of study, attracting attention from various disciplines such as political science, law, economics, and sociology. The aim of this paper is to explore on the basis of a literature review, what factors influence the support for basic income among the population. A systematic literature review based on the Web of Science and Scopus databases, after screening 2623 publications, identified 23 articles that contained findings relevant to the research question. A significant number of authors (12/23) analyzed data from the same source, the European Social Survey 2016 (ESS Round 8, 2020), conducted in 2016, first published in 2017 and updated several times since then. The paper shows that the study of the topic has a strong European focus. The social, economic, social and cultural diversity of European countries makes these studies important from a European and EU perspective, but from an international perspective, further research on the topic is needed.

Noise Reduction Methods in the Vehicle Industry: Using Vibroacoustic Simulation for Sustainability

Ambrus Zelei Krisztián Horváth

Publication Name: Chemical Engineering Transactions

Publication Date: 2024-01-01

Volume: 114

Issue: Unknown

Page Range: 763-768

Description:

To achieve sustainability goals, such as greenhouse gas emissions and environmental noise reduction, continuous innovation plays a key role in the vehicle industry. The noise emitted by vehicles negatively impacts both the environment and public health, making the development of noise reduction strategies crucial. Vibroacoustic simulation methodologies provide an opportunity to optimise vehicle power transmission systems by reducing the emitted noise level. Besides, the energy efficiency and performance of the vehicles can be improved by vibroacoustic simulations. In this research, a vibroacoustic simulation methodology is presented, focusing on the power transmission systems of vehicles. This approach integrates the Finite Element Method and Multibody Dynamics simulations with vibroacoustics to identify and redesign noisy components even during the conceptual design stage. This approach tackles the challenge of high-frequency tonal noise for electric vehicles, using psychoacoustic reviews to enhance passenger comfort. Key tasks involve electromagnetic force analysis in the drivetrain, structural vibration simulations, and noise reduction strategy optimisation using machine learning algorithms to reduce the reliance on physical prototypes. Capturing the current momentum of the industry, machine learning capabilities in vibroacoustic models can help engineers identify sources and eliminate or mitigate noise in the early design phase. Reducing the number of prototypes leads to more sustainable design processes. Our study shows the noise level can be reduced by 3-5 dB. This is particularly important in the context of electric vehicles, where high-frequency tone noise should be reduced, benefiting both passengers and their environment. Improving these factors is in line with the goals of the United Nations and improves the quality of urban life. Our research highlights the importance of vibroacoustic simulation and opens new directions in the field of noise reduction, promoting the spread of sustainable transport solutions.

Volume: Unknown

Issue: Unknown

Page Range: 809-816

Description:

The aim of the present study is to analyze the relationship between information accessibility and career decision making among first-year university students from a Central Eastern European university (n=2,330). Hierarchical cluster analysis was conducted based on motivational factors and four distinct student groups were identified: ‘Independent Decision Makers’ (IDM, 15.4%), ‘Amenity-Oriented Selectors’ (AOS, 41.2%), ‘Location-Centric Choosers’ (LCC, 16.6%), and ‘Academic Excellence Seekers’ (AES, 26.8%). While IDMs made decisions independent of institutional attributes, AOS prioritized university services, LCC were influenced by the city, and AES emphasized academic course quality. The most relevant sources of information are the official website of the National Office of Admissions, university websites, peer opinions, and institutional information. These findings provide important insights for universities and their targeted enrollment campaigns to understand the different decision-making preferences of students.
