M-commerce applications have evolved out of e-commerce applications, riding on the rapid advancement in mobile communication technologies in the past decade. The diffusion of applications on the Internet into the mobile computing environment has taken an accelerating pace ever since. Virtually all e-commerce and m-commerce applications rely on the provision of information retrieval and processing capability. In this regard, database systems serve as the information source and repository for these applications, backed by efficient indexing mechanism. Bean (2003) gave a good report on supporting Web-based e-commerce with XML, which could be easily extended to m-commerce. An m-commerce framework, based on JINI/XML and a workflow engine, was also defined by Shih and Shim (2002). Customers can receive m-commerce services through the use of mobile devices, such as pocket PCs, PDAs, or even smart phones. These mobile devices together with their users are often modeled as mobile clients. Central to supporting m-commerce applications are three types of entities: mobile device, mobile communication, and database. In particular, we are more interested in providing efficient access mechanisms to mobile-client-enabled database servers, which are often called mobile databases. Mobile databases contain the core information to support the underlying m-commerce applications, while the use of mobile devices serves for the hardware platform, with mobile communication providing the necessary connection between mobile databases and mobile devices for interfacing with real users or customers.

Due to the rapid advancement of mobile communication technologies, the demands for managing mobile devices effectively to fulfill various functionalities are on the rise. It is well known that mobile devices make use of different kinds of modulation approaches to adapt to various channel conditions. Therefore, in this paper, the authors propose a framework of Modulation Module Update (MMU) for updating the modulation module on the mobile device based on OMA DM. The management object for updating modulation module and the parameters associated with it are defined in the framework, and three operation phases are defined in this framework as well.

Now a day’s mobile communication has become a serious business tool for the users. Mobile devices are mainly used for the applications like banking, e-commerce, internet access, entertainment, etc. for communication. This has become common for the user to exchange and transfer the data. However people are still facing problems to use mobile devices because of its security issue. This paper deals with various security issues in mobile computing. It also covers all the basic points which are useful in mobile security issues such as categorisation of security issues, methods or tactics for success in security issues in mobile computing, security frameworks.

The report presents the author’s experience in integrating modern ICT technologies in the process of teaching and learning in school. The emphasis is on the use of mobile devices and the integration of cloud technologies in schools. As an ICT teacher, the author provides some practical guidelines on how to apply innovation. The generation of 7 screens does not know a world without digital technologies and mobile communications. The discrepancy between the expectations of the digital generation and the reality in our schools is in terms of the information and communication technologies (ICT) used in them and the didactic models. Adolescents, when they find themselves in an environment that does not meet their expectations, are demotivated and redirect their attention to other objects and goals and stop being active in class. The use of the so-called. „Cloud“ technologies will significantly increase the interest and retention of students. The modern approach to building information systems is focused on developing solutions in which the collection, input and output of information is carried out through WEB-based applications or platforms.

Over the past decades, waves of political contention involving the use of information and communication technologies have swept across the globe. The phenomenon stimulates the scholarship on digital communication technologies and contentious collective action to thrive as an exciting, relevant, but highly fragmentary and contested field with disciplinary boundaries. To advance the interdisciplinary understanding, Shifting Dynamics of Contention in the Digital Age outlines a communication-centered framework that articulates the intricate relationship between technology, communication, and contention. It further prods us to engage more critically with existing theories from communication, sociology, and political science on digital technologies and political movements. Given the theoretical endeavor, Shifting Dynamics of Contention in the Digital Age systematically explores, for the first time, the influence of mobile technology on political contention in China, the country with the world’s largest number of mobile and Internet users. Using first-hand in-depth interview and fieldwork data, it tracks the strategic choice of mobile phones as repertoires of contention, illustrates the effective mobilization of mobile communication on the basis of its strong and reciprocal social ties, and identifies the communicative practice of forwarding officially alleged “rumors” as a form of everyday resistance. Through this ground-breaking study, Shifting Dynamics of Contention in the Digital Age presents a nuanced portrayal of an emerging dynamics of contention—both its strengths and limitations—through the embedding of mobile communication into Chinese society and politics.

In March of 2020, the COVID-19 outbreak forced people to lock themselves inside their homes and begin the process of transitioning from face-to-face activities at work, schools and universities to a 100 % virtual method. Even when Communication Technologies (ICT) and online platforms have seen growth over the past two decades, including various virtual libraries developed by database publishers or web-based training programs that appear to shorten the learning curve (Lee, Hong y Nian, 2002), many people were unprepared for this transition and all of them are now dedicated to entering the new reality. In this order of ideas, the activities that have traditionally required the assistance of the staff have had to adapt with the use of new tools, which meet daily needs. A clear example is the field work collection tasks. In this group, there are different types such as surveys, photographs, reviews or on-site inspections. The current work presents the use of tools for collecting, validating, analysing and presenting data remotely and in real time. All of them based on the ArcGIS Online platform.

Increases in mobile phone ownership and Internet access throughout Africa continue to motivate initiatives to use information and communication technologies (ICTs)—in particular, mobile phones—to address long-standing socioeconomic problems in the “developing world.” While it is generally recognized that mobile phones may help to address these problems by providing pertinent information, less widely known is exactly how (and if) a handset’s human–computer interface—that is, its software and hardware design—supports this form of communication. The concept of “affordances” has long been used to answer such questions. In this paper, we use Hartson’s definition of affordances to qualitatively investigate rural Kenyan women’s interactions with their mobile phones. Our detailed analysis provides empirically grounded answers to questions about the cognitive, physical, and sensory affordances of handsets used in our field sites and how they support and/or constrain mobile communication. We then discuss the implications of our findings: in particular, how this affordance-based approach draws attention to mobile phones’ design features and to the context in which they and their users are embedded—a focus which suggests new design and research opportunities in mobile communication.
