In search of model for evaluating the quality of e-commerce websites

The nature of e-commerce is diverse. E-commerce has been categorized into business-to-consumer (B2C), business-to-business (B2B), business-to-government (B2G), consumer-to-consumer (C2C) etc. Users of e-commerce websites may be consumers, software developers/ designers, business/ service providers, business partners, suppliers, governments etc. Researchers have also shown that there are several perspectives about evaluation on quality for e-commerce websites, that is, one may take an approach or combination of approaches like product quality, systems as product quality, service quality of provider, quality of service offered and quality of the Human Computer Interface (HCI) design. This paper documents the review of literature on models for evaluating the quality of e-commerce websites and argues that there is still a lack of research in the area because of the inherent diversity of e-commerce

A Blockchain-Enabled IoT Logistics System for Efficient Tracking and Management of High-Price Shipments: A Resilient, Scalable and Sustainable Approach to Smart Cities

The concept of a smart city is aimed at enhancing the quality of life for urban residents, and logistic services are a crucial component of this effort. Despite this, the logistics industry has encountered issues due to the exponential growth of logistics volumes, as well as the complexity of processes and lack of transparency. Consequently, it is necessary to develop an efficient management system that offers traceability and condition monitoring capabilities to ensure the safe and high-quality delivery of goods. Moreover, it is crucial to guarantee the accuracy and dependability of distribution data. In this context, this paper proposes a blockchain-enabled IoT logistics system for the efficient tracking and management of high-price shipments. A smart contract based on blockchain technology has been designed for automatic approval and payment, with the aim of distributing shipping information exclusively among legitimate logistics parties. To ensure authentication, a zero-knowledge proof is used to conceal the blockchain address. Moreover, an intelligent parcel (iParcel) containing piezoresistive sensors is developed to pack delivered goods during the shipping process for violation detection such as severe falls or theft. The iParcels are automatically tracked and traced, and if a violation occurs, the contract is cancelled, and payment is refunded. The transaction fee per party is reasonable, particularly for high-price products that guarantee successful shipment
