Mobile Wearable Communications

This special issue provides the latest research and development on wireless mobile wearable communications. According to a report by Juniper Research, the market value of connected wearable devices is expected to reach $1.5 billion by 2014, and the shipment of wearable devices may reach 70 million by 2017. Good examples of wearable devices are the prominent Google Glass and Microsoft HoloLens. As wearable technology is rapidly penetrating our daily life, mobile wearable communication is becoming a new communication paradigm. Mobile wearable device communications create new challenges compared to ordinary sensor networks and short-range communication. In mobile wearable communications, devices communicate with each other in a peer-to-peer fashion or client-server fashion and also communicate with aggregation points (e.g., smartphones, tablets, and gateway nodes). Wearable devices are expected to integrate multiple radio technologies for various applications' needs with small power consumption and low transmission delays. These devices can hence collect, interpret, transmit, and exchange data among supporting components, other wearable devices, and the Internet. Such data are not limited to people's personal biomedical information but also include human-centric social and contextual data. The success of mobile wearable technology depends on communication and networking architectures that support efficient and secure end-to-end information flows. A key design consideration of future wearable devices is the ability to ubiquitously connect to smartphones or the Internet with very low energy consumption. Radio propagation and, accordingly, channel models are also different from those in other existing wireless technologies. A huge number of connected wearable devices require novel big data processing algorithms, efficient storage solutions, cloud-assisted infrastructures, and spectrum-efficient communications technologies.

Indoor and Outdoor monitoring of photocatalytic activity using a mobile phone app. and a photocatalytic activity indicator ink (paii)

A resazurin (Rz) based photocatalyst activity indicator ink (paii) is used to test the activity of commercial self-cleaning materials. The semiconductor photocatalyst driven colour change of the ink is monitored indoors and outside using a simple mobile phone application that measures the RGB colour components of the digital image of the paii-covered, irradiated sample in real time. The results correlate directly with those generated using a traditional, lab-bound method of analysis (UV–vis spectrophotometry).

Match-fixing and Money-laundering

his essay is premised on the following: a conspiracy to fix or otherwise manipulate the outcome of a sporting event for profitable purpose. That conspiracy is in turn predicated on the conspirators’ capacity to: (a) ensure that the fix takes place as pre-determined; (b) manipulate the betting markets that surround the sporting event in question; and (c) collect their winnings undetected by either the betting industry’s security systems or the attention of any national regulatory body or law enforcement agency.

Unlike many essays on this topic, this contribution does not focus on the “fix”– part (a) of the above equation. It does not seek to explain how or why a participant or sports official might facilitate a betting scam through either on-field behaviour that manipulates the outcome of a game or by presenting others with privileged inside information in advance of a game. Neither does this contribution seek to give any real insight into the second part of the above equation: how such conspirators manipulate a sports betting market by playing or laying the handicap or in-play or other offered betting odds. In fact, this contribution is not really about the mechanics of sports betting or match fixing at all; rather it is about the sometimes under explained reason why match fixing has reportedly become increasingly attractive as of late to international crime syndicates. That reason relates to the fact that given the traditional liquidity of gambling markets, sports betting can, and has long been, an attractively accessible conduit for criminal syndicates to launder the proceeds of crime. Accordingly, the term “winnings”, noted in part (c) of the above equation, takes on an altogether more nefarious meaning.

This essay’s attempt to review the possible links between match fixing in sport, gambling-related “winnings” and money laundering is presented in four parts.

First, some context will be given to what is meant by money laundering, how it is currently policed internationally and, most importantly, how the growth of online gambling presents a unique set of vulnerabilities and opportunities to launder the proceeds of crime. The globalisation of organised crime, sports betting and transnational financial services now means that money laundering opportunities have moved well beyond a flutter on the horses at your local racetrack or at the roulette table of your nearest casino. The growth of online gambling platforms means that at a click it is possible for the proceeds of crime in one jurisdiction to be placed on a betting market in another jurisdiction with the winnings drawn down and laundered in a third jurisdiction and thus the internationalisation of gambling-related money laundering threatens the integrity of sport globally.

Second, and referring back to the infamous hearings of the US Senate Special Committee to Investigate Organised Crime in Interstate Commerce of the early 1950s, (“the Kefauver Committee”), this article will begin by illustrating the long standing interest of organised crime gangs – in this instance, various Mafia families in the United States – in money laundering via sports gambling-related means.

Third, and using the seminal 2009 report “Money Laundering through the Football Sector” by the Financial Action Task Force (FATF, an inter-governmental body established in 1989 to promote effective implementation of legal, regulatory and operational measures for combating money laundering, terrorist financing and other related threats to the integrity of the international financial system), this essay seeks to assess the vulnerabilities of international sport to match fixing, as motivated in part by the associated secondary criminality of tax evasion and transnational economic crime.

The fourth and concluding parts of the essay spin from problems to possible solutions. The underlying premise here is that heretofore there has been an insularity to the way that sports organisations have both conceptualised and sought to address the match fixing threat e.g., if we (in sport) initiate player education programmes; establish integrity units; enforce codes of conduct and sanctions strictly; then our integrity or brand should be protected. This essay argues that, although these initiatives are important, the source and process of match fixing is beyond sport’s current capacity, as are the possible solutions.

The significance of bruising in the pre-mobile infant

The majority of children in our society are loved andcherished. The occasional cases of intentional injury to a childresulting in death or significant harm evoke powerful anduncomfortable feelings (Devaney et al, 2013), and the publicoutcry may result in health and social workers facing criticism.Identifying whether an infant is at risk of abuse is a challengefor practitioners, and can be a source of stress and anxiety(Brandon et al, 2011). Bruising is a strong indicator of childabuse involving intentional injury (Kemp et al, 2014). Theincidence of bruising correlates to developmental stage, withnon-mobile infants least likely to incur bruising. Therefore, itspresence in pre-mobile infants requires immediate assessment.A search of the literature around bruising in pre-mobile infantsrevealed themes of missed opportunities for early intervention,the role of the father in the family and the significance of childdevelopment. Sharing of knowledge and expertise within themultidisciplinary team is key to safeguarding infants.

Mining Money: the generative capacities of scientific and legal knowledge practices in the making of resource economies

In 1997 a scandal associated with Bre-X, a junior mining firm, and its prospecting activities in Indonesia, exposed to public scrutiny the ways in which mineral exploration firms acquire, assess and report on scientific claims about the natural environment. At stake here was not just how investors understood the provisional nature of scientific knowledge, but also evidence of fraud. Contemporaneous mining scandals not only included the salting of cores, but also unreliable proprietary sample preparation and assay methods, mis-representations of visual field estimates as drilling results and ‘overly optimistic’ geological reports. This paper reports on initiatives taken in the wake of these scandals and prompted by the Mining Standards Task Force (TSE/OSC 1999). For regulators, mandated to increase investor confidence in Canada’s leading role within the global mining industry, efforts focused first and foremost upon identifying and removing sources of error and wilfulness within the production and circulation of scientific knowledge claims. A common goal cross-cutting these initiatives was ‘a faithful representation of nature’ (Daston and Galison 2010), however, as the paper argues, this was manifest in an assemblage of practices governed by distinct and rival regulative visions of science and the making of markets in claims about ‘nature’. These ‘practices of fidelity’, it is argued, can be consequential in shaping the spatial and temporal dynamics of the marketization of nature.

Footprints in the sand: a persistent spatial impression of fishing in a mobile groundfish assemblage

Fishing is well known to curtail the size distribution of fish populations. This paper reports the discovery of small-scale spatial patterns in length appearing in several exploited species of Celtic Sea demersal 'groundfish'. These patterns match well with spatial distributions of fishing activity, estimated from vessel monitoring records taken over a period of 6 years, suggesting that this 'mobile' fish community retains a persistent impression of local-scale fishing pressure. An individual random-walk model of fish movement best matched these exploitation 'footprints' with individual movement rates set to <35 km per year. We propose that Celtic Sea groundfish may have surprisingly low movement rates for much of the year, such that fishing impact is spatially heterogeneous and related to local fishing intensity.

Towards a Mobile Assistive Technology for Monitoring and Assessing Cognitive Fatigue in Individuals with Acquired Brain Injury

Those living with an acquired brain injury often have issues with fatigue due to factors resulting from the injury. Cognitive impairments such as lack of memory, concentration and planning have a great impact on an individual’s ability to carry out general everyday tasks, which subsequently has the effect of inducing cognitive fatigue. Moreover, there is difficulty in assessing cognitive fatigue, as there are no real biological markers that can be measured. Rather, it is a very subjective effect that can only be diagnosed by the individual. Consequently, the traditional way of assessing cognitive fatigue is to use a self-assessment questionnaire that is able to determine contributing factors. State of the art methods to evaluate cognitive! fa tigue employ cognitive tests in order to analyse performance on predefined tasks. However, one primary issue with such tests is that they are typically carried out in a clinical environment, therefore do not have the ability to be utilized in situ within everyday life. This paper presents a smartphone application for the evaluation of fatigue, which can be used daily to track cognitive performance in order to assess the influence of fatigue.

A Fast Algorithm for Sparse Support Vector Machines for Mobile Computing Applications

This research presents a fast algorithm for projected support vector machines (PSVM) by selecting a basis vector set (BVS) for the kernel-induced feature space, the training points are projected onto the subspace spanned by the selected BVS. A standard linear support vector machine (SVM) is then produced in the subspace with the projected training points. As the dimension of the subspace is determined by the size of the selected basis vector set, the size of the produced SVM expansion can be specified. A two-stage algorithm is derived which selects and refines the basis vector set achieving a locally optimal model. The model expansion coefficients and bias are updated recursively for increase and decrease in the basis set and support vector set. The condition for a point to be classed as outside the current basis vector and selected as a new basis vector is derived and embedded in the recursive procedure. This guarantees the linear independence of the produced basis set. The proposed algorithm is tested and compared with an existing sparse primal SVM (SpSVM) and a standard SVM (LibSVM) on seven public benchmark classification problems. Our new algorithm is designed for use in the application area of human activity recognition using smart devices and embedded sensors where their sometimes limited memory and processing resources must be exploited to the full and the more robust and accurate the classification the more satisfied the user. Experimental results demonstrate the effectiveness and efficiency of the proposed algorithm. This work builds upon a previously published algorithm specifically created for activity recognition within mobile applications for the EU Haptimap project [1]. The algorithms detailed in this paper are more memory and resource efficient making them suitable for use with bigger data sets and more easily trained SVMs.

Sharing services, saving money? Five risks to cost saving when organizations share administrative services

Shared services are a popular reform for governments under financial pressure. The hope is to reduce overheads and increase efficiency by providing support services like HR, finance and procurement once to multiple agencies. Drawing on insights from organization theory and political science, we identify five risks that shared services won’t live up to current expectations. We illustrate each with empirical evidence from the UK, Ireland and further afield, and conclude with suggestions on how to manage these risks.

Event-driven implicit authentication for mobile access control

In order to protect user privacy on mobile devices, an event-driven implicit authentication scheme is proposed in this paper. Several methods of utilizing the scheme for recognizing legitimate user behavior are investigated. The investigated methods compute an aggregate score and a threshold in real-time to determine the trust level of the current user using real data derived from user interaction with the device. The proposed scheme is designed to: operate completely in the background, require minimal training period, enable high user recognition rate for implicit authentication, and prompt detection of abnormal activity that can be used to trigger explicitly authenticated access control. In this paper, we investigate threshold computation through standard deviation and EWMA (exponentially weighted moving average) based algorithms. The result of extensive experiments on user data collected over a period of several weeks from an Android phone indicates that our proposed approach is feasible and effective for lightweight real-time implicit authentication on mobile smartphones.
