Access to broadband communications in different parts of the world has become a priority for some governments and regulatory authorities around the world in recent years. Building new digital roads and pursuing a connected society includes looking for easier access to the Internet. In general, not all the areas where people congregate are fully covered, especially in rural zones, thus restricting access to data communications and bringing inequality. In the present review article, we have comprehensively surveyed the use of three platforms to deliver broadband services to such remote and low-income areas are proposed: Unmanned Aerial Vehicles (UAV), Altitude Platforms (APS), and Low-Earth Orbit (LEO) satellites. These novel strategies support the connected and accessible world hypothesis. Hence UAVs are considered a noteworthy solution since their efficient maneuverability can aboard the rural coverage issues or not-spots.

Access to the internet is fast becoming a basic right given the plethora of information available on the net these days. In the current scenario, the issue of internet shutdown has become an important concern in India. Internet shutdown affects people socially, psychologically and economically. On one hand, many democratic countries of the world are discussing about digital freedom and human rights, while on the other hand, some countries including India are continuously practicing Internet shutdowns in different parts of their countries. India has become the top country of the world in terms of the numbers of Internet shutdowns. The Internet has become such a prominent source of information for all of us that when Internet connectivity is suspended, many people are affected as they depend on the Internet services for various purposes. Internet shutdown is not only harmful to democracy and governance but also to the economy of the country. Internet shutdowns are direct violations of digital freedom and human rights. The main objective of this paper is to argue that access to internet is a basic right and highlight the problem of Internet shutdown in India and its adverse impact on the lives of Indians. In addition, this paper attempts to highlight a brief history of Internet shutdowns in India. The paper shows how frequent clampdowns on internet affects the economy, as has been the case of Union Territory of Jammu & Kashmir thereby highlighting the case for internet freedom for the survival of the economy especially in Digital India.

The Internet has become an essential element of all society today. Those who can access the World Wide Web have become active participants in the Information Age. Unfortunately, many individuals throughout the world do not have ready access to the needed technology. Furthermore, they do not have the required knowledge and skills to use the technology and cannot participate actively. As a result, this has created a world of information haves and have-nots. In this chapter, after examining the concept of the digital divide, data is presented that shows that those with low incomes and those who are older have little access to technology and the use of computers. Low-income seniors are especially limited in their opportunities to own a computer, and they seldom have the skills needed to use one for e-mail, search the Internet, and so forth, even if they visit a public library where they could use a computer without any cost. Various approaches being used to help seniors learn how to use computers are described, andthen the chapter focuses on two projects that have proved to be successful in this effort. SeniorNet is a national organization that helps establish learning centers around the country. The approach used at one such center, located at Nova Southeastern University in South Florida, requires seniors to pay for their courses. A second project is known as SeniorComp and is supported by private foundation funds. Ten low-income senior citizens are selected for each group of seniors in this project. They are given a complete Dell computer system, and their tuition is paid to take four of the SeniorNet courses. At the end of the fourth course, ownership of the computer system is turned over to the individual participant. To date, the completion rate has been 100%. The approaches used can serve as models for others to modify and use in their own communities. By adopting a similar approach, the impact of the digital divide can be significantly reduced for those low-income seniors that participate in the project. In this way, this portion of the marginal community can be empowered.

AbstractSatellite cloud imagery is a standard tool of meteorology, and also of ground-based observational astronomy. Fast access to cloud imagery through the Internet now permits more accurate prediction of local cloud cover than was formerly the case. This is particularly useful for automatic and remotely operated telescopes, where an observer may be at a considerable distance from the telescope itself. Since satellite imagery can now be accessed through the Internet with such ease, direct reception of radio transmissions from weather satellites may seem unnecessary. However, advances in computing power and radio receiver technology permit simple automated receipt of satellite transmissions, particularly from the NOAA series of low Earth orbit satellites. This has the advantage of more up-to-date, and higher resolution, cloud imagery than can be obtained from the Internet. We have operated such a satellite receiving station since 2003 April, and have found it particularly useful when remotely operating our telescopes at Siding Spring Observatory (SSO). By automatically publishing our cloud imagery onto the World Wide Web we have established a resource that is widely used by other local observatories and by the general public.

Advance fee fraud (AFF) involves an offender using deceit to obtain a financial gain from the victim. The victim believes that by forwarding a sum of money, there will be a future ‘pay-off’. The most commonly witnessed forms of AFF perpetrated via the Internet include classic ‘Nigerian’ or ‘419’ scams, investment fraud and romance fraud. Because of the largely transnational nature of AFF offending, where the victim and offender typically reside in different parts of the world, police are adapting their traditional and reactive approaches to more innovative strategies to combat this crime more effectively. This article utilises a qualitative, semi-structured interview design to explore the experiences of police detectives involved in the implementation of an early intervention model with victims of AFF. The study highlights the challenges involved in developing effective police strategies to proactively reduce the duration and severity of this type of financial victimisation.

Background: One of the main obstacles to malaria control in the world has been the emergence of resistance in Plasmodium falciparum to chloroquine and other antimalarial drugs. This study aimed to review studies in Iran on resistance in P. falciparum and P. vivax to drugs, and to reveal the mechanisms and molecular markers of resistance of these two species. Methods: The databases of PubMed, Scopus, Google Scholar, Magiran, and reputable Iranian journals were searched to find published studies on the resistance in P. falciparum and P. vivax to antimalarial drugs in Iran. Results: There is a significant relationship between resistance to chloroquine in P. falciparum and the emergence of K76T mutation in the P. falciparum chloroquineresistance transporter gene in Iran. Resistance to sulfadoxine-pyrimethamine (SP) in P. falciparum is also significantly associated with the development of mutations in the dihydrofolate reductase and dihydropteroate synthase genes. Resistance to chloroquine in P. vivax has not been reported in Iran and it is used as a first-line treatment for P. vivax malaria. Conclusion: P. falciparum has become resistant to chloroquine in different regions of Iran and is not currently used to treat malaria. Besides, cases have emerged of P. falciparum resistance to SP in different parts of southern Iran, and SP is not administered alone for treating P. falciparum.

The threat of cyber-related crimes due to excessive usage of Internet and current e-behaviour amongst the younger children is not new in this new millennium but stays as an issue for consideration. This paper provide a general pattern of online related behaviours that seem to be taking place among Malaysian pre-adolescents and adolescents and its possible impact on their behaviours leading towards cyber-related crimes. Facts and finding from various researches conducted from different parts of the world, including Malaysia were reviewed. The results from various studies reveal that a great concern and strategies have to be put into place as the age group using the Internet has reduced and the routine activity of pre-adolescence and adolescence are changing and are based on Internet. Non-awareness of their current online behaviours and its possible link to cyber-related crimes may lead these young children to a greater threat when using e-Commerce or any other Internet dependent activities in the future. This paper focuses on the facts collected from various studies to justify the importance of having future research on this phenomenon.

At its core, the Internet is a communication medium. As such, it can enable social interactions between people in different parts of the world and at different times. The last technological innovation that changed the way we communicate so drastically was the telephone. Its social impact has been dramatic and the Internet is already influencing our lives just as significantly. In this chapter I describe the use of a small part of the Internet by a specific social group. I will discuss the issues surrounding the use of an Internet-based newsgroup dedicated to organ transplantation. My observations will primarily deal with organ transplant recipients and their use of this newsgroup to define a new identity for themselves after the disorienting lifesaving procedure of a foreign organ grafted onto their bodies.

Purpose – This paper aims to research as to how Twitter is influential as an electronic word-of-mouth (e-WOM) communication tool and thereby affecting movie market. In present days, social media is playing an important role in connecting people around the globe. The technology has provided a platform in the social media space for people to share their experiences through text, photos and videos. Twitter is one such online social networking media that enables its users to send and read text-based messages of up to 140 characters, known as “tweets”. Twitter has nearly 200 million users and billions of such tweets are generated by users every other day. Social media micro-blogging broadcasting networks such as Twitter are transforming the way e-WOM is disseminated and consumed in the digital world. Twitter social behaviour for the Hollywood movies has been assessed across seven countries to validate the two basic blocks of the honeycomb model – sharing and conversation. Twitter behaviour was studied for 27 movies in 22 different cities of seven countries and for six genres with a total tweets of 9.28 million. The difference of Twitter social media behaviour was compared across countries, and “sharing” and “conversation” as two building blocks of the honeycomb model were studied. t-Test results revealed that the behaviour is different across countries and across genres. Design/methodology/approach – The objective of the paper is to analyse Twitter messages on an entertainment product (movies) across different regions of the world. Hollywood movies are released across different parts of the world, and Twitter users are also in different parts of the world. The objective is to hence validate “conversation” and “sharing” building blocks of the honeycomb model. The research is confined to analysing Twitter data related to a few Hollywood movies. The tweets were collected across nine different cities spanning four different countries where English language is prominent. To understand the Twitter social media behaviour, a crawler application using Python and Java was developed to collect tweets of Hollywood movies from the Twitter database. The application has incorporated Twitter application programming interfaces (APIs) to access the Twitter database to extract tweets according to movies search queries across different parts of the world. The searching, collecting and analysing of the tweets is a rather challenging task because of various reasons. The tweets are stored in a Twitter corpus and can be accessed by the public using APIs. To understand whether tweets vary from one country to another, the analysis of variance test was conducted. To assess whether Twitter behaviour is different, and to compare the behaviour across countries, t-tests were conducted taking two countries at a time. The comparisons were made across all the six genres. In this way, an attempt was made to obtain a microscopic view of the Twitter behaviour for each of the seven countries and the six genres. Findings – The findings show that the people use social media across the world. Nearly 9.28 million tweets were from seven countries, namely, USA, UK, Canada, South Africa, Australia, India and New Zealand for 27 Hollywood movies. This is indicative of the fact that today, people are exchanging information across different countries, that people are conversing about a product on social media and people are sharing information about a product on social media and, thus, proving the hypothesis. Further, the results indicate that the users in USA, Canada and UK, tweet more than the other countries, USA and UK being the highest in tweets followed by the Canada. On the other hand, the number of tweets in Australia, India and South Africa are low with New Zealand being the lowest of all the countries. This indicates that different countries’ users have different social media behaviour. Some countries use social media to communicate about their experience more than in some other country. However, consumers from all over the world are using Twitter to express their views openly and freely. Originality/value – This research is useful to scholars and enterprises to understand opinions on Twitter social media and predict their impact. The study can be extended to any products which can lead to better customer relationship management. Companies can use the Internet and social media to promote and get feedback on their products and services across different parts of the world. Governments can inform the public about their new policies, benefits of governmental programmes to people and ways to improve the Internet reach to more people and also for creating awareness about health, hygiene, natural calamities and safety.
