The study of disinformation and media manipulation has expanded greatly since 2016, leading to thousands of news stories and academic studies. As an interdisciplinary field, it has attracted a wide variety of scholars using multiple methods and theories to understand how communication technologies shape politics and society, including how hoaxes, lies, scams, and strategic misinformation reach millions in an instant. However, because of the diversity of approaches and lines of inquiry, it is not an easy area of study to grasp at first glance. What’s more, the concerns, be they medical misinformation or foreign influence operations, are sociotechnical in nature—meaning they are the product of both sociocultural and technological conditions that cannot be separated from one another. The stakes could not be higher, as the world witnessed how disinformation was a core mobilizing factor in the genocide in Myanmar and the siege on the US Capitol. Yet strategies to counter the harms of media manipulation and disinformation require rigorous and nuanced research drawing from ethnography to data science. This chapter therefore aims to make sense of misinformation research as an expanding subdomain of critical internet studies, offering an overview of the methods and theories of inquiry, current research and findings, and paths forward for future research.

Construction project management requires effective and real time information and data communication between all the project team agencies. In present scenario when the associating agencies may be geographically separated, and for projects with large site areas or being executed in hazardous or remote sites, the required information and data communication can be achieved through use of mobile communications. But, research shows that the adoption of mobile communications by the construction industry is limited. This chapter presents the issues affecting adoption of mobile communications by the construction industry, the research background, a case study of mobile communications adoption at a major construction project in India and further discusses the factors leading to sustainable mobile communication adoption by construction project teams. Construction industry primarily comprises small and medium enterprises (SMEs). Thus, the issues are studied with focus on adoption of mobile communications by SMEs.

<p>There has been a tremendous growth in Information and Communication technologies during the last decade. Internet has become the dominant media for data communication. But the secrecy of the data is to be taken care. Steganography is a technique for achieving secrecy for the data communicated in Internet. This paper presents a review of the steganography techniques based on least significant bit (LSB) substitution and pixel value differencing (PVD). The various techniques proposed in the literature are discussed and possible comparison is done along with their respective merits. The comparison parameters considered are, (i) hiding capacity, (ii) distortion measure, (iii) security, and (iv) computational complexity.</p>

Face‐to‐face business meetings are a widely used method of group interaction, and a rich source of data on what actually happens in group discussions. Active participation in a meeting is usually perceived to be making an oral contribution of some kind to the discussion. This paper describes a field study of ten face‐to‐face business meetings which were videotaped and subsequently analysed. Participant contributions were coded, and the data summarized. The mean contribution was approximately 12 seconds and 18 words. The most common contribution type was information giving. The highest single contributor in each meeting captured, on average, about 30% of the available airtime, while the two highest, combined, captured over half of the airtime. These findings are discussed within the context of requirements for designers of collaborative technology systems to support group interpersonal communication through the use of computing and data communication technologies.

With the ongoing trends in the energy sector such as vehicular electrification and renewable energy, the Smart Grid (SG) is clearly playing a more and more important role in the electric power system industry. One essential feature of the SG is the information flow over high-speed, reliable, and secure data communication networks in order to manage the complex power systems effectively and intelligently. SGs utilize bidirectional communication to function whereas traditional power grids mainly only use one-way communication. The communication requirements and suitable techniques differ depending on the specific environment and scenario. In this paper, we provide a comprehensive and up-to-date survey on the communication technologies used in the SG, including the communication requirements, physical layer technologies, network architectures, and research challenges. This survey aims to help the readers identify the potential research problems in the continued research on the topic of SG communications.

As the existing communication technologies which for about a decade have supported railway operations and the huge transition from conventional to modern communication-based signaling approach the extent of their performance capabilities, the railway industry strives to migrate to a proven solution aiming to support the new and diverse broadband services and reduce cost. Long Term Evolution (LTE) radio access technology has been globally accepted because of the unparalleled performance, off-the-shelf convenience, and well-developed standardization. An LTE solution, however, brings both the opportunities and challenges to a Data Communication System (DCS) underlying a Communication-Based Train Control (CBTC) system. The presented research targets one of the main LTE deployment challenges; the spectrum availability. To cope with the increasing scarcity of spectrum resources, LTE/LTE-A has envisaged an extension to the unlicensed band which is already heavily populated with incompatible legacy systems such as the immensely popular Wi-Fi networks. In this paper, a design framework is established to dimension the LTE system according to the CBTC DCS sub-system level requirements. Furthermore, the LTE/Wi-Fi coexistence performance is evaluated and studied in a train control application’s context by using a Markov chain analysis approach.

The growth of technological capabilities of mobile devices, the evolution of wireless communication technologies, and the maturity of embedded systems contributed to expand the Machine to machine (M2M) concept. M2M refers to data communication between machines without human intervention. The objective of this paper is to present the grand schemes of a model to be used in an agricultural Decision support System. The authors start by explaining and justifying the need for a hybrid system that uses both Multi-Agent System (MAS) and Constraint Programming (CP) paradigms. Then, the authors propose an approach for Constraint Programming and Multi-Agent System mixing based on controller agent concept. The authors present concrete constraints and agents to be used in a distributed architecture based on the proposed approach for M2M services and agricultural decision support. The platform is built in Java using general interfaces of both MAS and Constraint Satisfaction Problem (CSP) platforms and the conception is made by agent UML (AUML).
