Emerging wireless personal area networks(WPANs) : - An analysis of techniques, tools and threats

Wireless Personal Area Networks provide a pivotal role in local area network technology complementing traditional Wireless Local Area Network technologies. Bluetooth, ZigBee and NFC (Near Field Communications) have emerged as key WPAN technologies with UWB (Ultra Wide Band) standards currently evolving. They are however subject to the usual range of security vulnerabilities found in wireless LANs such as spoofing, snooping, man-in-the-middle, denial of service and other attacks. However security in WPANs is not as mature as it is in Wireless LANs and further work is needed in order to provide comparable protection. This paper examines a range of WPAN technologies and security issues and proposes protection mechanisms that can mitigate risk in each case. © 2012 IEEE.

A review of the current status of mobile apps in education - implication for emerging countries business education strategies

Mobile applications (in short: mobile apps) are software applications designed to run on mobile devices such as smart phones and tablet computers. These technologies have come a long way since the opening of the Apple App Store in 2008, especially in their applications for business, information, communication, health and gaming. Most mobile devices are capable of processing and disseminating information in an efficient way. Smart devices, such as the iPhone or iPad, are equipped with innovative functionalities and unique features for easy delivery of content, information sharing, and collaborative work over the Internet. This is the basis for the use of these technologies in the education industry.

Organisational learning as an emerging process: the generative role of digital tools in informal learning practices

 Increasing attention is paid to organisational learning, with the success of contemporary organisations strongly contingent on their ability to learn and grow. Importantly, informal learning is argued to be even more significant than formal learning initiatives. Given the widespread use of digital technologies in the workplace, what requires further attention is how digital technologies (eg, massive open online courses—MOOC) enable informal learning processes. Drawing from Complex Adaptive Systems (CAS) theory, in this paper we advance a conceptual model for examining this important topic. The two dimensional matrix and the micro-level description of informal learning activities presented provide a framework for both further research on technology-mediated practices for informal learning, as well as the design of formative contexts for learning to occur.

Additive manufacturing technologies : 3D printing, rapid prototyping, and direct digital manufacturing

This book covers in detail the various aspects of joining materials to form parts. A conceptual overview of rapid prototyping and layered manufacturing is given, beginning with the fundamentals so that readers can get up to speed quickly. Unusual and emerging applications such as micro-scale manufacturing, medical applications, aerospace, and rapid manufacturing are also discussed. This book provides a comprehensive overview of rapid prototyping technologies as well as support technologies such as software systems, vacuum casting, investment casting, plating, infiltration and other systems. This book also: Reflects recent developments and trends and adheres to the ASTM, SI, and other standards Includes chapters on automotive technology, aerospace technology and low-cost AM technologies Provides a broad range of technical questions to ensure comprehensive understanding of the concepts covered.

Urbanization, openness, emissions, and energy intensity: a study of increasingly urbanized emerging economies

This paper analyses the impact of urbanization and trade openness on emissions and energy intensity in twenty-two increasingly urbanized emerging economies. We employ three second-generation heterogeneous linear panel models as well as recently developed nonlinear panel estimation techniques allowing for cross-sectional dependence. The empirical results show that population density and affluence increase emissions and energy intensity while renewable energy seems to be dormant in these emerging economies, but non-renewable energy increases both CO2 emissions and energy intensity. In addition, openness significantly reduces both pollutant emissions and energy intensity whereas urbanization significantly increases energy intensity, but it is insignificant in increasing emissions. This may be, in part, due to the recent increasing trend in adopting cleaner technologies in these increasingly urbanized developing economies.

Media technologies and publics

“Making and Shaping Publics: Discourse and Technology” is composed of five different positions on how media technologies shape publics, and how new and emerging publics construct identities and strategic goals. This section of Contemporary Publics begins with an introduction where media technologies are utilised to facilitate progressive change. This facilitative role is examined in subsequent chapters, where publics can unite around discourse and technology that enables communication and identity creation. The negative consequences of technologies in making and shaping publics are also examined, particularly with respect to privacy. Overall, various responses have emerged from the ways in which media and discursive practices attempt to fold us into particular kinds of publics. The chapters in this section observe how publics react to forms of control.
