From the first satellite launched in 1957, these systems always have drawn the attention of telecommunications operators. Thanks to their natural orbit, satellites can provide coverage to the entire globe or serve a vast region. Is this feature that makes them potential systems to extend current ground networks over the space. The first satellites were conceived as a single backhaul system to broadcast television or phone calls. Over the years, this concept evolved to a group of satellites that compose a constellation to interconnect any user around the globe. Nowadays, these constellations are still evolving to massive architectures with thousands of satellites that are interconnected between them composing satellite networks. Additionally, with the emergence of 5G, the community has started to discuss how to integrate satellites in this infrastructure. A review of the evolution of the satellites for broadband communications is presented in this chapter, discussing the novel and future proposed architectures. The presented work concludes with the potential of these satellite systems to compose a hybrid and heterogeneous architecture in which space, air, and ground networks become interconnected.

Purpose – Activities such as making personal phone calls, surfing on the internet, booking personal appointments or chatting with colleagues may or may not deviate attentions from work. With this in mind, the purpose of this paper is to examine gender differences and motivations behind personal activities employees do at work, as well as individuals’ perception of the time they spend doing these activities. Design/methodology/approach – Data were obtained from 35 individuals (M age=37.06 years; SD=7.80) from a Portuguese information technology company through an ethnographic method including a five-day non-participant direct observation (n=175 observations) and a questionnaire with open-ended questions. Findings – Results revealed that during a five-working-day period of eight hours per day, individuals spent around 58 minutes doing personal activities. During this time, individuals engaged mainly in socializing through conversation, internet use, smoking and taking coffee breaks. Results revealed that employees did not perceive the time they spent on non-work realted activities accurately, as the values of these perceptions were lower than the actual time. Moreover, through HLM, the findings showed that the time spent on conversation and internet use was moderated by the relationship between gender and the leisure vs home-related motivations associated with each personal activity developed at work. Originality/value – This study contributes to the literature on human resource management because it reveals how employees often perceive the time they spend on non-work related activities performed at work inaccurately. This study highlights the importance of including individual motivations when studying gender differences and personal activities performed at work. The current research discusses implications for practitioners and outlines suggestions for future studies.

Abstract The pundits of the money world tell us to be a “dotcom” or enable them for excitement and rewards. Traffic on the Internet Highway is certainly stepping up the pace as “slow” electrons make way for ultimate-speed photons creating major hardware opportunities. The “Copper Road” has become the “Glass Super Highway” as long-haul terrestrial and underwater communications links move up to Advanced Photonics. Nothing can be faster than light, but more important, no other medium can offer wider bandwidth when wave-multiplexing strategies are used. Photonics, employing dense wave division multiplexing (DWDM) can carry the equivalent of 12,000 encyclopedias or 5-million phone calls on a single fiber. Recent advances in photonics hardware, including higher-powered lasers, more efficient amplifiers and cleaner optical fiber are enabling incredible bandwidth for the Internet and general communications services. But how do we route a light beam? The long-haul segments of the Internet, now mostly fiberoptics, have been converting modulated light to electronic signals, routing with conventional electronic hardware and then re-converting back to light. Yes, O-E-O (Opto-electro-opto) works, but with cost and time-delay penalties. The communications industry has decreed that the double conversion process must go, but what technology will be the replacement? Enter optical MEMS, or MOEMS (micro-opto-electro-mechanical systems). The MOEMS switch/router approach was endorsed by the Internet carrier and hardware industry that paid billions of dollars in 2000 to acquire MEMS companies, some that had not even shipped a product. But what are the issues and are there competing technologies that could win? Micro-mirror technology is at the top of the popularity chart right now. Can MOEMS mirror routers solve cost problems and can they even switch at the rates demanded. What is the ideal mirror switch strategy: binary “off/on” or point-to-light pipe arrays? What about other MEMS approaches such as micro-bubble fluid beam refraction that appears to offer a much simpler construction? Maybe the mechanical devices are only an interim destined to obsolescence by a future solid state optics switch. The optical switch, powered totally by photons, is already in the lab and could be the final answer. This paper will survey MOEMS inside the Internet to seek answers to the billion dollar questions. The focus will be on micro-mirrors and their packaging issues both inside and out. We will deal with selecting the ideal optical MEMS package and choosing the right atmosphere control. Certain in-package contaminants are death to mirrors, but they can be controlled even if generated after the package is sealed. So tune in to find out if MEMS can catch the WAVE!

This paper attempts to provide an alternative perspective of Abdullah Hussain’s Interlok (2010) by examining the original version of the novel published in 1971. Exploring the controversy through claims made by the general public, academics and experts through the Internet, we argue that those who found the novel racist in essence are themselves guilty of racism. The paper will further suggest that Abdullah Hussain is a fierce nation builder who attempts to redefine the nation’s idea of citizenship and nationhood that can be explained by using the Race Relations Cycle theory. Most importantly, the article demonstrates the writer’s desire to try and redefine citizenship among the Malaysian people by deconstructing well-perceived stereotypical race constructions and promoting unity in a new nation. Keywords: Interlok, racism, nationalism, Abdullah Hussain

This paper aims to investigate the prevalence of cyberbullying among Vietnamese adolescents. Special emphasis was placed on gender differences regarding different forms of cyberbullying and victimization. In this study, 200 middle school students from four state schools in Vietnam were online surveyed to obtain information about the prevalence of cyberbullying and victimization. The results show that most of the students used the Internet daily and that almost all of them possess mobile telephones. On average, 7% of students reported that they have cyberbullied others online, whilst 14% of them were victims of cyberbullying. The most common types of victimization reported by students were harassment including “prank or silent phone calls” or “Insults on instant messaging and website”. There were not any significant gender differences in cyberbullying and being victimized by cyberbullies than females.

Abstract Postproverbiality, the novel perspective to studying proverbs, has focused mainly on the radical revision of African proverbs. However, this phenomenon is not only found in African proverbs, but also in many other languages as already suggested in literature. Therefore, this study investigates postproverbiality in English proverbs as used on social media, particularly Twitter. Twitter is especially known for people’s display of radical ideologies, opinions, and idiosyncrasies; therefore, it serves as a useful source for such radical revision of English proverbs. The analysis was done using Jacob Mey’s (2001) Pragmatic Acts as theoretical framework. The data was purposively gathered using five standard English proverbs to search for postproverbial versions; a total of thirty postproverbials were discovered on Twitter. The analysis revealed ten practs and allopracts which include affirming, insisting, informing, counselling, warning, instructing, and encouraging. These were projected through contextual features of shared situational knowledge, voicing, inference, metaphor, and socio-cultural knowledge. The interaction among the textual and contextual features and the allopracts shows that cultures and occurrences in public affairs affect such cultural indices as proverbs and language use and this interaction increases through the internet and social networks which link the world into a global community.

CAPTCHAs are employed on websites to differentiate between human users and bot programs that indulge in spamming and other fraudulent activities. With the advent and advancement of sophisticated computer programs to break CAPTCHAs, it has become imperative to continuously evolve the CAPTCHA schemes in order to keep the Internet network and website free of congestion and spam-bots. In light of these developments concerning information security, in this chapter, the authors introduce the novel concept of Scrambled CAPTCHA, which is a combination of OCR-based and Picture CAPTCHAs and exploits an inherent characteristic of human vision and perception. They also introduce Hindi CAPTCHA, developed in Hindi language (Devanagari script). This CAPTCHA will typically address spamming on Indian websites. It also contributes to the digitalization of books written in this script. The authors also discuss the features and security aspects of these schemes in detail, which, to the best their knowledge, had not been implemented earlier.

Abstract Policy makers in regions such as Europe are increasingly concerned about the trustworthiness and sovereignty of the foundations of their digital economy, because it often depends on systems operated or manufactured elsewhere. To help curb this problem, we propose the novel notion of a responsible Internet, which provides higher degrees of trust and sovereignty for critical service providers (e.g., power grids) and all kinds of other users by improving the transparency, accountability, and controllability of the Internet at the network-level. A responsible Internet accomplishes this through two new distributed and decentralized systems. The first is the Network Inspection Plane (NIP), which enables users to request measurement-based descriptions of the chains of network operators (e.g., ISPs and DNS and cloud providers) that handle their data flows or could potentially handle them, including the relationships between them and the properties of these operators. The second is the Network Control Plane (NCP), which allows users to specify how they expect the Internet infrastructure to handle their data (e.g., in terms of the security attributes that they expect chains of network operators to have) based on the insights they gained from the NIP. We discuss research directions and starting points to realize a responsible Internet by combining three currently largely disjoint research areas: large-scale measurements (for the NIP), open source-based programmable networks (for the NCP), and policy making (POL) based on the NIP and driving the NCP. We believe that a responsible Internet is the next stage in the evolution of the Internet and that the concept is useful for clean slate Internet systems as well.
