Musings on the Metaverse and on how the Internet of Digital Reality Encompasses Future Developments of the Internet

Gyorgy Wersenyi

Publication Name: Infocommunications Journal

Publication Date: 2023-01-01

Volume: 2023

Issue: Unknown

Page Range: 21-28

Description:

Internet of Digital Reality (IoD) is a concept that encompasses various aspects of the next level of communication between digital cognitive entities. Extending the concept of IoT and IoE, IoD includes all kinds of entities interacting in virtual reality, focusing not only on the technology, physical and logical networks, but also on cognitive aspects and human factors. The Metaverse – as a key element of IoD – was introduced and has lately been re-vitalized as a kind of vision for the future of the Internet, especially focusing on social media, where users interact via their avatars in a fully immersive VR scenario. In this paper, I nevertheless argue that IoD is more than a “VR Facebook”, and that although the Metaverse can offer a new kind of experience, it isn’t free from drawbacks and valid criticisms.

Spatial spread of pandemics – Spatial relations of the five wave of the Covid-19 pandemic on the example of Győr-Moson-Sopron County

Szabolcs Morvay Judit Berkes Zsolt Szakály Szentes Veronika

Publication Name: Statisztikai Szemle

Publication Date: 2023-01-01

Volume: 101

Issue: 8

Page Range: 739-755

Description:

Many disciplines deal with the analysis of the spread of epidemics (or pandemics). Spatial relations and regional inequalities are the determining variables of the intensity, extent and severity of the spread of an epidemic, so it is essential to investigate epidemics from a regional perspective. Mathematical, statistical, network, and spatial simulation models can be used in spatial analysis for investigating the spread of epidemics. In this study, statistical methods are used as a basis. A possible way to reduce the severity of epidemics – be it health or economic effects – is to slow down the intensity of the spread. To this end, we carried out the retrospective study and examined the Győr-Moson-Sopron county during the period when the pandemic caused by the Covid-19 coronavirus was most intense in our country, just as it was in most countries of the world, too.

Evaluation of a CUSUM-Type Changepoint Detector Applied in the Time-Frequency Domain of Synthetic Road Vehicle Vibrations

Peter Foldesi László Róbert Hári

Publication Name: Lecture Notes in Mechanical Engineering

Publication Date: 2023-01-01

Volume: Unknown

Issue: Unknown

Page Range: 812-823

Description:

Non-stationary random vibrations gained increasing interest in vibration testing. Often, a changepoint detection procedure handles the decomposition of Road vehicle vibrations (RVV) when analysing the recorded series. Unfortunately, only subjective justifications support the proposed methods, and mainly the validation of the non-stationarity of simulated signals is concerned. Thus, if a detector is inherent to the procedure, it is also recommended to calibrate it. The current paper concerns the Receiver operating characteristics (ROC) of a CUSUM-type algorithm and supplies contextual support by Segment length distributions (SLD).

Cooperation and Sustainability in Last-Mile Logistics Sector: Behavioural Aspects of Courier Express Parcel Service Providers

Edit Süle Csilla Bartucz

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 565-570

Description:

The decisions of company managers are often not guided by the regulations governing the environment but by subjective factors that exert their effects in a hidden way in the decision-making manager's behavior. Market behavior is objectively controlled by regulators, but subjective factors lead to poor decision-making in some cases. On the one hand, the principal-agent problem is revealed behind the subjective factors, and on the other, cognitive biases affect the decision-making leader as a person. Cooperation with competitors from the same sector and sustainability issues are two similar areas where there is an opportunity to examine these concerns and where the nature of companies' decision-making shows similar or identical patterns on the basis of which decision-making behavior can be explored, characterized, and understood. This thesis examines the attitude of the managers of two existing Courier, Express, and Parcel market players regarding possible market cooperation. In-depth interviews and the completion of a unique questionnaire that revealed the presence of cognitive bias were the basis for the research. During the investigation, the cognitive bias influencing the decision of the two company managers was identified, and it was also examined whether the parent company or the owner's opinion affected their decision. The two case studies demonstrate how managers' decisions to develop collaborations are influenced by their prior experiences and prejudices.

Sustainability trends in the wine industry: Cognitive biases and methodological insights from a PRISMA review

Boglárka Eisingerné Balassa Agnes Csiba-Herczeg Réka Koteczki

Publication Name: Ecocycles

Publication Date: 2023-01-01

Volume: 9

Issue: 3

Page Range: 90-102

Description:

Sustainability—the characteristic, property, and goal of every responsible, mature, rational, and environmentally sensitive organization—has gained undeniable and incredible traction in the wine industry over the last few decades, influencing wine-making procedures and packaging. Determined actors inside and outside the industry have identified key environmental concerns, such as energy efficiency or recycling, that support promoting a sustainable industry. To explore how sustainability is implemented in the wine sector, we, the authors of this paper, conducted a systematic literature review methodology. The PRISMA model served as our primary criteria for focusing the literature search and was utilized in its execution. Our study analyses thirty scholarly publications, which are categorized according to three primary themes: (1) Wineries and Sustainability; (2) Wineries and Cognitive Biases; and (3) Wineries and Sustainability and Cognitive Biases. The novelty of the study lies in its use of a systematic literature review (SLR) to investigate the complex interaction between wine, cognitive biases, and sustainability with a combined focus. The findings point to the understudied domain of consumers' cognitive biases regarding alternate wine packaging. Our results show that there is potential for improvement in the wine sector in terms of sustainable packaging and the consumer behavior of accepting or rejecting specific packaging options. These areas are considered worthy of future holistic approach investigation because alternative packaging is critical to making the industry more environmentally friendly. Still, if consumers cannot accept and purchase wine thus packaged, such raises further questions. Our study may be helpful to stakeholders in the wine sector as practitioners increasingly seek to incorporate and promote sustainable practices in their operations.

How Consumers Accept Unmanned Smart Stores? – Introducing a Proposed Technology Acceptance Model

Marta Konczosne Szombathelyi Szabolcs Ramhap Eszter Szabó-Szentgróti Petra Kinga Kézai

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 373-378

Description:

Digitalization and technological innovation have revolutionized the retail sector. In recent years, a new trend has emerged in the form of unmanned stores, pioneered by Amazon Go. Unmanned solutions using artificial intelligence are beginning to enter the public consciousness and represent a new sustainability perspective (such as lowering paper waste, packaging or using sustainable construction materials) in trade. Although it is not yet widespread and is still a new solution for consumers, the global market dynamics suggest that it will expand in the future. Unmanned shops pose some challenges, but these can be effectively addressed by the appropriate introduction of new technology. To identify or filter out potential shortcomings of this technology on the consumer side, it is also necessary to examine the acceptance of this technology by customers. In this paper, the internationally accepted Extended Unified Theory of Acceptance and Use of Technology (UTAUT2) model was modified and used to examine how consumers accept this technology. For data analysis, Partial Least Squares-Structural Equation Modelling method was applied. In the proposed model six constructs were examined on how they influence the intention to use. In the performed query, Hungarian university students’ behavioural intention is influenced by performance expectancy, effort expectancy, and hedonic motivation. However social influence, atmosphere, and price sensitivity have no significant influence on use intention.

Remarks on the genus Phymatodiscus Berlese, 1917, with the description of Phymatodiscidae fam. nov. and Bardizon eotvosi gen. nov., sp. nov. from Indonesia (Acari, Mesostigmata)

Sergey G. Ermilov Jenő Kontschán

Publication Name: Zookeys

Publication Date: 2023-01-01

Volume: 1182

Issue: Unknown

Page Range: 223-235

Description:

Phymatodiscidae fam. nov. is diagnosed, with Phymatodiscus as the type genus. A new genus, Bardizon gen. nov., with Bardizon eotvosi sp. nov. (from Indonesia) as the type species, is erected to accommodate the Phymatodiscus species with an eye-like dorsal depression. Six Phymatodiscus species are reclassified as Bardizon: B. aokii (Hiramatsu, 1985), comb. nov., B. haradai (Hiramatsu, 1985), comb. nov., B. oculatus (Hirschmann, 1977), comb. nov., B. kuni (Kontschán & Starý, 2011), comb. nov., B. insolitus (Kontschán & Ripka, 2016), comb. nov., and B. malayicus (Kontschán & Starý, 2012), comb. nov. The new species differs from the previously described congeners in the sculptural pattern, the shapes of the dorsal and ventral setae, and the sculptural pattern of the sternal shield of the male and the genital shield of the female. A list of all known phymatodiscid species is presented. Phymatodiscus titanicus (Berlese, 1905) is moved to the genus Bostocktrachys: B. titanicus (Berlese, 1905), comb. nov. (family Trachyuropodidae).

A Linear Driver Model of Local Path Planning for Lane Driving

Ernö Horváth Gergo Igneczi Krisztian Nyilas

Publication Name: Sisy 2023 IEEE 21st International Symposium on Intelligent Systems and Informatics Proceedings

Publication Date: 2023-01-01

Volume: Unknown

Issue: Unknown

Page Range: 103-108

Description:

Modern lane centering assistance systems often use the mid-lane as a reference line for tracking. However, human drivers prefer to keep an offset to the mid-lane. Therefore, we have proposed in our previous work a driver model which calculates human-like offset values and enable the path planner to plan human-like paths. The driving data of 15 drivers have been analyzed. It has been revealed that drivers behave differently in left or right curves and choose to drive on either the left or the right side in straight road sections. Therefore, we extend our model to handle these traits. We have shown that the extended model outperforms the previous symmetric model.

The Legal Status of Independent Regulatory Organs and Their Place in the Hungarian State Administration

János Kálmán

Publication Name: Public Governance Administration and Finances Law Review

Publication Date: 2023-01-01

Volume: 8

Issue: 1

Page Range: 105-119

Description:

Independent regulatory organs as a type of administrative body were included among the central state administrative bodies upon the entry into force of the Fundamental Law of Hungary. The key feature of independent regulatory organs is that they also have the power to legislate within the framework of the regulatory authority’s activity; in other words, they can intervene in the relations of their administered sector through the creation of generally binding rules of conduct, which are enforced through the official activities falling within their scope of duties and powers. The characteristics of the legal status of independent regulatory organs and the components of their independence are therefore of particular importance in the system of public administration. The content and strength of their independence are not identical but are adapted to the professional content and EU and constitutional requirements of the specialised area of administration for which the Fundamental Law authorises the National Assembly to establish these bodies.
