Game Model of Optimal Quality Experience Strategy for Internet of Vehicles Bandwidth Service Based on DAG Blockchain

With the rapid development of the Internet of Vehicles (IoV), vehicle networks will generate large amounts of data. Vehicle-to-Vehicle (V2V) data sharing can improve driving experience and quality of service, and Vehicle-to-Roadside unit (V2R) communication can improve road transport efficiency. A certain amount of bandwidth is consumed in the process of data sharing between V2V and V2R, and when multiple vehicles request data from the RSU at the same time, there may be network delay or congestion. Therefore, the vehicle obtains data faster by requesting high bandwidth from the RSU. However, since the bandwidth resources of RSUs are limited, optimal bandwidth service strategies need to be investigated. In addition, in order to ensure the safety, efficiency and traceability of data sharing between V2V and V2R, a blockchain-supported IoV needs to be established. Therefore, we design a blockchain-based framework for V2V and V2R transaction framework that integrates DAG blockchain and modern cryptography. The framework ensures security and scalability during the execution of data exchange and completion of bandwidth transactions, improves the service quality of vehicles and realizes decentralized payment. In this work, a two-stage Stackelberg game is established under two pricing schemes of uniform pricing and discriminatory pricing to jointly maximize the benefits of vehicles and RSUs. In Stage I, the RSU sets the corresponding bandwidth service and pricing strategy. In Stage II, the vehicle decides the service demand according to the observed pricing strategy. The optimal bandwidth allocation and pricing strategy between the RSU and the vehicle is determined through the game of both parties, and the existence and uniqueness of the two-stage subgame Nash equilibrium is analyzed by applying backward induction. The correctness of the model is verified by experiments, and the comparative analysis shows that the proposed model has high throughput.

Disentangling completed transactions in the UK: experiences and challenges

The UK has a voluntary, non-suspensory merger control regime, such that mergers, acquisitions and other transactions can be, and routinely are, completed before they are investigated by the CMA. However, the CMA can, and often does, investigate mergers, acquisitions and other transactions that have not been notified to it. It has powers to prevent further integration between the merging parties’ businesses, and to require existing integration to be unwound, pending the conclusion of its investigation. Where the CMA identifies competition concerns, whether at Phase 1 or Phase 2, the fact that a merger, acquisition or other transaction has been completed can give rise to difficulties in identifying, implementing and ensuring the effectiveness of a remedy. This article discusses the CMA’s powers to impose interim measures and its approach to remedies in completed transactions. It also discusses the lessons that the CMA has learned from implementing remedies in merger investigations into completed transactions.

Cryptocurrency Abuse for the Purposes of Money Laundering and Terrorism Financing: Policies and Practical Aspects in the European Union and North Macedonia

The number of countries that express concern for the danger of using cryptocurrencies for illegal activities among which are money laundering and terrorism financing is increasing. Cryptocurrencies are virtual assets created and managed through advanced computer encryption and operate on a decentralized network known as a blockchain. The key issue of concern and attention in the world is the anonymity and pseudonymity of cryptocurrencies, which prevents proper monitoring of transactions by state institutions and allows the completion of suspicious transactions outside the regulated systems. The paper provides an overview and elaborates the existing European legal framework and the measures and activities undertaken by the Republic of North Macedonia, harmonized with the European ones, in the fight against money laundering and terrorist financing in the crypto sector. For that purpose, the legal documents adopted at EU level, as well as those adopted by North Macedonia are analyzed and discussed. At the end, the paper clearly brings out a major way in which the abuse on the use of crypto-currency can be stopped at the international level.

Consumer Intention to Switch from Cash to Mobile Payment in Restaurants During and After Pandemic

ABSTRACT During the Covid-19, more and more consumers complete transactions on mobile devices and enjoy their orders at home. However, it is unknown whether mobile payment will become normal when they return to restaurants. Results show that the perceived inconvenience of cash, the perceived convenience of mobile payment and deal proneness facilitate the intention of consumers to switch to mobile payments. The perceived security and privacy, perceived health risk, consumer innovativeness, and social influence have a direct bearing on consumer intent to switch to mobile payment and moderate switching intention. This study also provides theoretical and managerial implications.

SoK: DAG-based Blockchain Systems

Limitations on high latency and low scalability of classical blockchain systems retard their adoptions and applications. Reconstructed blockchain systems have been proposed to avoid the consumption of competitive transactions caused by linear sequenced blocks. These systems, instead, structure transactions/blocks in the form of Directed Acyclic Graph (DAG) and consequently rebuild upper layer components. The promise of DAG-based blockchain systems is to enable fast confirmation (complete transactions within million seconds) and high scalability (attach transactions in parallel) without significantly compromising security. However, this field still lacks systematic work that summarises DAG techniques. To bridge the gap, this Systematization of Knowledge (SoK) provides a comprehensive analysis of ever-existing and ongoing DAG-based blockchain systems. We abstract a general model to capture the main features and identify six types of design patterns. Then, we evaluate these systems from the perspectives of structure, consensus, property, security, and performance. We further discuss the trade-off between different factors, open challenges, and the potentiality of DAG-based solutions, indicating their promising directions for future research.

Post-COVID-19 Real Estate Net Absorption and Social Capital in U.S. Metropolitan Areas

The authors of this article studied the differential impact of the COVID-19 pandemic on the performance of office real estate markets using a sample of major U.S. metropolitan areas. During the pandemic, social capital became a significant determinant of net absorption and mitigated the decline in net absorption due to the impact of COVID-19. They found that social capital in U.S. metropolitan areas as measured by the density of social networks has a significant positive effect on net absorption in a post-COVID-19 period. The results suggest that social capital contributes to an increase in net absorption values by promoting trust and communication among members of a community, which increases the likelihood of a completed transaction resulting in more leasing contracts.

Factors Affecting Acceptance of E-Wallets Among UiTM Melaka Students

In the modern era, e-wallets have evolved into crucial mobile applications. It replaces conventional payment methods like using cash and debit or credit cards to complete transactions after making a purchase of goods or services. This study will examine university students' acceptance of using the Technology Acceptance Model (TAM) to determine whether they are willing to use the applications or whether they reject them. 210 students took part in the study and answered the online questionnaire that was distributed using Google Form. The demographic profile of the respondents, as well as the three TAM components that were used in this study—perceived usefulness (PU), perceived security (PS), and perceived ease of use (PEU)—were analysed. Additionally, this study examined the students at UiTM Melaka's willingness or actual use (AU) in relation to their behavioral intention (BIU). The results of the Pearson Correlation analysis revealed a positive and significant relationship between UiTM Melaka students' behavioral intention to use an e-wallet and perceived usefulness and perceived security, but the relationship became positive but insignificant with perceived ease of use. Perceived usefulness, on the other hand, emerged as the most important factor that affected respondents' behavioral intention to use an e-wallet, according to the results of the multiple linear regression analysis. The behavioral intention to use an e-wallet also demonstrated a positive influence on actual e-wallet use among UiTM Melaka students. Therefore, the research's findings were helpful in assisting businesses and the application's developer in enhancing their features and offerings, particularly regarding the safety and usability of the systems.

Are Online-Only Real Estate Marketplaces Viable? Evidence from China.

Online businesses have been surging worldwide during the past decade, especially during the recent COVID-19 epidemic. However, the market share of online real estate transactions is still limited, mainly due to the information-asymmetry problem. In this study, we manually collect data on online judicial housing auctions in China, which is currently the largest online real estate market globally, and investigate how information disclosure facilitates real estate transactions. The empirical results suggest that disclosing better quality information online can attract more potential buyers. In particular, providing more comprehensive information such as professional appraisal reports or videos of the property can help to convert buyers’ initial interests into completed transactions and higher sales proceeds. The positive effects of information are particularly strong when combined with offline services, in a more mature online market, and for low-value properties. We also provide preliminary analysis of factors affecting online-information-disclosure quality from both the macro and micro perspectives. We also provide preliminary analysis of factors affecting online-information-disclosure quality from both the macro and micro perspectives.

Modelling the Impacts of Social Value on Platform Identity: The Mediating-Moderating Research Design in Live-Streaming Context

In the era of digitalization and epidemic, more people deeply rely on digital tools. Digital tools can be used to complete transactions for food delivery, daily necessities and car booking. Live broadcasting is one of the representative products in the digital era. Users’ perceived social value and its impacts are important to the society and operators of platform. Fewer studies, however, have verified the relationships among social value, platform dependence, and platform identity. Accordingly, the research purpose of this paper is to analyze users' digital inertia, social values, and the relationships among their dependence and their identity on livestreaming platforms. Data was collected by questionnaire survey and 372 valid samples were received. Findings show that in the relationships between live streaming platforms and users, positive relationships among variables were met; the social value perceived by the users could affect platform identity through platform dependence; and users' perceived digital inertia significantly could moderate the relationship between social value and platform dependence. It is suggested that operators should strengthen users' perception of social value when designing live broadcast activities.

Informal land transactions and demolition of houses in Cameroon

The objective of the study is to assess the impact of informal land transactions on the risk of house demolitions. A combination of theoretical and empirical tools as well as data obtained from the Demographic and Health Survey (DHS, Enquêtes Démographiques et de Santé. Cameroun, 2011), have made it possible to arrive at two significant conclusions: (i) the completion of an informal land transaction increases by 9.4% the risk of the demolition of housing and (ii) the risks of house demolitions are higher in urban areas within poor households with a low level of education, with the tendency towards informal land transactions on average increase by 49%. These results suggest the implementation of inclusive public policies in terms of land supply and housing. They also suggest placing the problem of informal land transactions in a more global perspective including income, enlightenment on land matters and employment policies to reduce the vulnerability of the disadvantaged strata.

Application of Blockchain in Artificial Intelligence

Abstract: Artificial intelligence (AI) refers to the simulation of human intelligence in machines designed in such a way that machines can think like humans and imitate their actions. It combines sub-fields for machine learning and in-depth learning, using data-trained AI algorithms to make predictions or categories, and become smarter over time. The benefits of AI include automated repetitive tasks, improved decision-making and better customer experience. Blockchain is a shared, unchanging platform that provides fast, shared and transparent data exchange at the same time across multiple groups as they begin and complete transactions. The blockchain network can track orders, payments, accounts, production, and more. Because members are allowed to share a common vision, they gain confidence and trust in their work and other businesses, as well as new efficiency and opportunities. AI can successfully mine with a large database and create new environments and discover patterns based on data behaviour. Blockchain helps to effectively remove bugs and counterfeit data sets. The two technologies complement each other as Blockchain can reduce the risk to AI, and AI can improve Blockchain performance. Much research is currently being done on the use of Blockchains to detect intelligent applications in key areas such as health care, finance, power, government, and defense.

GIS information structure for real estate cadastral valuation

Currently, one of the country's most valuable resources is real estate. Real estate has a special economic and social status; that’s why the legislators of various countries impose special requirements for the registration of real estate transactions. On the basis of the documents on the completed transaction, the transfer of ownership is made by making changes to the real estate register. This article describes the procedure of cadastral valuation and using geoinformation systems in the process of such valuation. The authors note the importance of cadastral valuation for the country's economy. For a deeper understanding, the stages of this procedure as well as advantages and disadvantages of the existing software package are investigated here. The authors also propose the information structure of the geoinformation system, which will be used to determine the cadastral value of the assessed object.

Blockchain-based power trading system for microgrid

Direct trading between entities in the microgrid is the trend of micro-grid electricity trading. However, the lack of trust and endorsement among multiple entities in micro-grids makes it difficult to complete direct electricity transactions, which limits the green energy efficiency. To solve this problem, firstly, a blockchain-based microgrid power transaction level model and power transaction process management process are proposed. Secondly, an access interface between the microgrid smart terminal and the blockchain is designed to realize the connection between the blockchain and the underlying equipment. The system is implemented in an island microgrid, which realizes the peer-to-peer trading between power suppliers and users. The system builds a bridge among entities in microgrid and makes the power trading open, transparent and traceable.
