Contemporary Digital Forensic Investigations of Cloud and Mobile Applications comprehensively discusses the implications of cloud (storage) services and mobile applications on digital forensic investigations. The book provides both digital forensic practitioners and researchers with an up-to-date and advanced knowledge of collecting and preserving electronic evidence from different types of cloud services, such as digital remnants of cloud applications accessed through mobile devices. This is the first book that covers the investigation of a wide range of cloud services. Dr. Kim-Kwang Raymond Choo and Dr. Ali Dehghantanha are leading researchers in cloud and mobile security and forensics, having organized research, led research, and been published widely in the field. Users will gain a deep overview of seminal research in the field while also identifying prospective future research topics and open challenges

The local press has always played a central role in the Portuguese society. Recently, new innovative technological projects to develop mobile applications and focus on local journalism in Portugal have emerged. These initiatives allow the development of better and more appealing services for local users. However, due to the important social role of the local press, this also brings along some responsibilities. Our main research goal is to study the accessibility issues in local journalism in Portugal. To this end, we first describe the current situation of local journalism in Portugal and some accessibility issues raised by the appearance of mobile applications. We then develop a simple checklist that allows the assessment of whether these applications have prevented social exclusion and facilitated the access of local information to a wide range of users, including disabled citizens. This tool provides the regional news publisher with information to improve its democratization of access to local information in Portugal. Using the cognitive walkthrough method, we illustrate the proposed framework by presenting case studies of five mobile applications in Portuguese local and regional press. This study concludes that despite the great potential that mobile applications showcase, several accessibility issues have not been properly addressed.

Competition for use of different mobile applications (apps) is intense. How to improve user loyalty to mobile apps is an urgent issue for enterprises to solve. Gamification has become an important means of attracting users' attention to apps. In this study 357 participants completed
a questionnaire assessing human–computer interaction, interpersonal interaction, perceived playfulness, user loyalty, and involvement with reference to the payment app Alipay and the game within it, . Structural equation modeling was performed and the results showed that both human–computer
interaction and interpersonal interaction promoted perceived playfulness, which contributed to user loyalty. Finally, involvement played a positive role in the relationship between perceived playfulness and user loyalty.
