High Speed Data

Purpose The purpose of this paper is to examine the current provision of high-speed data networks in the African continent, in particular taking into account both licences and launches related to long-term evolution (LTE). Design/methodology/approach An up-to-date underlying database of licences and launches relating to LTE in Africa has been compiled. There is also a review of the international operators that are playing a significant role in LTE provision. A number of individual country case studies are considered. Issues of corruption are addressed. Findings Africa is interesting because it has been a laggard in the development of high-speed data networks, but now finds itself in a position to leapfrog 3G technologies, and hence close the gap that had opened up compared to, for example, Europe and Asia. This process is effectively assisted by the lack of fixed-wire connectivity but has to take account of the difficulty of attracting the requisite investment. Research limitations/implications Databases relating to Africa are always difficult to compile. Originality/value Published work relating to mobile networks in Africa is not plentiful, and it is difficult to find relevant data in the public domain. A key aspect of the paper is that the database is entirely up-to-date.

Purpose The purpose of this paper is to examine in a fully up-to-date manner the position in respect of the licensing and launch of long-term evolution (LTE) (4G) in a region that attracts relatively little attention in academic work and the media. The purpose is also to examine the role of incumbency and to assess to what extent the licensing of LTE can make a difference to the structure of mobile markets in the region. Design/methodology/approach The first step has been to compile extensive databases with respect to the licensing and launch of high-speed networks in the region, arranged so as to emphasize the position of the dominant incumbents. A distinction is drawn between the larger, mainly Latin American, countries and the smaller, mainly Caribbean, islands. There is a discussion of new entry and its potential to disrupt incumbents. Findings The position of dominance held by two operators – América Móvil and Telefonica in the larger countries and by Digicel and Cable & Wireless Communications (Liberty Global) in the islands – is brought to the fore, and the analysis demonstrates that this is unlikely to be more than marginally affected by regulatory attempts to restructure markets by, for example, fostering new entry. Research limitations/implications This is necessarily an overview paper as more than 50 countries/islands are covered, so detailed individual country studies are precluded. Practical implications The way forward, such as it is, can only be illuminated by first clarifying the current state of play. Originality/value The databases that underpin the analysis are author-compiled and entirely original.

Purpose The internet of things (IoT) is becoming an increasingly inescapable part of society. IoT paradigm cannot function without the networking infrastructure. High-speed data networks are essential to enable the IoT future. Thus, the purpose of this study is on the identification of risks that influence the development, installation and operation of information and communication technology (ICT) infrastructure network project cost outcomes. So far, there has been little attention has been paid to risks problems in these types of IoT enabling projects. Design/methodology/approach This research follows a quantitative analysis approach. Data for this study were collected by a survey from 209 professionals. Multiple regression analysis was used to model the relationship between risks and outturn cost of infrastructure needed to enable the operation of IoT technologies. Findings The main risk factors that were identified were planning and development, people and management, operations, technology and hardware. Research limitations/implications This research has expanded the existing literature by documenting and clustering ICT infrastructure network project risks into themes, and has developed a scale (risk statements) for measuring such risks. Further, the research has advanced the understanding by identifying the most likely risks that will contribute to the overrun of these projects. Originality/value This research establishes a reliable regression method for the assessment of the risks that influence the development, installation and operation of ICT infrastructure network projects outturn cost. No other research has measured or studied the risks in this type of project.

New Entry

Purpose – This paper aims to investigate whether new entry via mobile licensing in Europe has had any longer-term consequences for competition. Design/methodology/approach – A database is presented covering certain recent periods and the issue of licences for the provision of 2G, 3G and 4G mobile services. Findings – It would appear that new entry has had very little overall effect on competition, although Hutchison Whampoa has, almost uniquely, forced a response from incumbents via a strategy of low prices, albeit without gaining significant market share at their expense. Research limitations/implications – Interpretation of databases cannot by its very nature be entirely free from ambiguity. Practical implications – In practice, given that very few 4G (long-term evolution) licence regulations have reserved spectrum for new entrants, it may be presumed that most regulators in European countries have already observed that such new entry as is likely to be attracted will take the form of poorly funded companies from outside the mobile sector rather than incumbents from other countries. Social implications – Choice of incumbent network is being reduced, although mobile virtual network operators remain active. The implications for prices and service quality are for now a matter of debate. Originality/value – The databases underpinning this analysis are not available from other sources in the private or public domain in the form presented in this paper.

Purpose The purpose of this paper is to examine in a fully up-to-date manner the position in respect to the licensing and launch of long-term evolution (LTE) in a region that attracts relatively little attention when treated as a whole because the emphasis is usually upon the very large individual markets (China, India and Japan) contained within it. The purpose is also to examine the role of international groups and the extent to which the licensing of LTE can make a difference to the structure of mobile markets in the region. Design/methodology/approach The initial step was to compile extensive databases with respect to the licensing and launch of high-speed networks in the region – defined both narrowly and also to encompass countries that are often treated as part of the Middle East – arranged so as to emphasise the status of dominant incumbents. There is a discussion of new entry and its potential to disrupt incumbents. Findings For historical reasons, the region contains countries that have strong differences whether defined in terms of economic, social or cultural characteristics, and hence it has not been easy for a network with international aspirations to expand outside its home market nor for, say, European-based operators to gain a foothold. Attempts to introduce competition via new licences has also been problematic because of the strong, and sometimes very large, incumbents already present. Research limitations/implications This is necessarily an overview that uses selected data to describe the overall picture because of the substantial number of quite different markets surveyed. Practical implications It is possible to forecast how certain structural changes will occur – primarily the withdrawal of international groups such as Millicom that prefer to concentrate upon other regions. Originality/value The databases that underpin the analysis are author-compiled and entirely original.

Purpose This paper aims to explore the reasons for and the subsequent longer-term impact of the closure of the Barlinnie Special Unit (BSU). Design/methodology/approach The paper is both descriptive, providing an overview of the work of the BSU, and conceptual in that it argues that the limits of “prisoner rehabilitation” are observed in the closure of the BSU, which sounds a warning for other penal therapeutic communities and what it means to operate effectively. Findings The BSU which assisted long-term, difficult and violent prisoners moderate their prison behaviour and then to live non-offending lives, lost the confidence of government ministers and officials, as well as senior prison managers and, seemingly, the public, so closed after being in operation for 21 years. The impact of this has been that the Scottish Prison Service has not introduced, or attempted to introduce, a similar regime for managing and treating violent and disruptive prisoners. Practical implications There are important lessons to be learned from the BSU experience for all who manage and work in specialist, prison therapeutic units or within prison therapeutic regimes. This includes balancing the therapeutic elements of the regime, which may involve engaging in practices which are outside the norm for custodial establishments, with those establishments’ security and operational requirements, so as to not to create a disconnect between addressing offending behaviour and maintaining expected standards of wider prison conduct. Originality/value While there have been previous evaluations of the BSU, the longer-term impact has neither been previously considered and nor has the unit’s closure been considered from a penal philosophical perspective.

PurposeThere are ethical, legal, social and economic arguments surrounding the subject of autonomous vehicles. This paper aims to discuss some of the arguments to communicate one of the current issues in the rising field of artificial intelligence.Design/methodology/approachMaking use of widely available literature that the author has read and summarised showcasing her viewpoints, the author shows that technology is progressing every day. Artificial intelligence and machine learning are at the forefront of technological advancement today. The manufacture and innovation of new machines have revolutionised our lives and resulted in a world where we are becoming increasingly dependent on artificial intelligence.FindingsTechnology might appear to be getting out of hand, but it can be effectively used to transform lives and convenience.Research limitations/implicationsFrom robotics to autonomous vehicles, countless technologies have and will continue to make the lives of individuals much easier. But, with these advancements also comes something called “future shock”.Practical implicationsFuture shock is the state of being unable to keep up with rapid social or technological change. As a result, the topic of artificial intelligence, and thus autonomous cars, is highly debated.Social implicationsThe study will be of interest to researchers, academics and the public in general. It will encourage further thinking.Originality/valueThis is an original piece of writing informed by reading several current pieces. The study has not been submitted elsewhere.

Purpose The purpose of this paper is to present a comparison between reluctance synchronous machine-enabling work at high internal temperature (HT° machine) with laminated and solid rotor. Design/methodology/approach To obtain heat sources for the thermal model, calculations of the electromagnetic field were made using the Opera 3D program including effect of rotation and the resulting eddy current losses. To analyse the thermal phenomenon, the 3D coupled thermal-fluid (CFD) model is used. Findings The presented results show clearly that laminated construction is much better from a point of view of efficiency and temperature. However, solid construction can be interesting for high speed machines due to their mechanical robustness. Research limitations/implications The main problem, despite the use of parallel calculations, is the long calculation time. Practical implications The obtained simulation and experimental results show the possibility of building a machine operating at a much higher ambient temperature than it was previously produced for example in the vicinity of the aircraft turbines. Originality/value The paper presents the application of fully three-dimensional coupled electromagnetic and thermal analysis of new machine constructions designed for elevated temperature.

Purpose – There are many different conceptualizations to sustainable development and these different approaches may have led to confusion amongst the public. The purpose of this paper is to explore the identities of the term and how the confused identity may be leading to problems for sustainable development efforts. Design/methodology/approach – The design is exploratory, using both secondary and primary data to understand the different sustainable development concepts. Findings – There is no consistent understanding or use of the term “sustainable development” among various groups. Research limitations/implications – Future research should include a larger sample that is more representative of people from different backgrounds and geographical areas. Practical implications – The public is generally willing to support only projects that it understands. Without a clear understanding of sustainable development, the public will be less inclined to support these efforts. Originality/value – This study examines the perceptions and understandings of the term by the general public representing different generations.

PurposeThe purpose of this study is to investigate communication on Twitter during two unpredicted crises (the Manchester bombings and the Munich shooting) and one natural disaster (Hurricane Harvey). The study contributes to understanding the dynamics of convergence behaviour archetypes during crises.Design/methodology/approachThe authors collected Twitter data and analysed approximately 7.5 million relevant cases. The communication was examined using social network analysis techniques and manual content analysis to identify convergence behaviour archetypes (CBAs). The dynamics and development of CBAs over time in crisis communication were also investigated.FindingsThe results revealed the dynamics of influential CBAs emerging in specific stages of a crisis situation. The authors derived a conceptual visualisation of convergence behaviour in social media crisis communication and introduced the terms hidden and visible network-layer to further understanding of the complexity of crisis communication.Research limitations/implicationsThe results emphasise the importance of well-prepared emergency management agencies and support the following recommendations: (1) continuous and (2) transparent communication during the crisis event as well as (3) informing the public about central information distributors from the start of the crisis are vital.Originality/valueThe study uncovered the dynamics of crisis-affected behaviour on social media during three cases. It provides a novel perspective that broadens our understanding of complex crisis communication on social media and contributes to existing knowledge of the complexity of crisis communication as well as convergence behaviour.
