On the Study of Network Coded AF Transmission Protocol for Wireless Multiple Access Channels

In this paper, the performance of the network coded amplify-forward cooperative protocol is studied. The use of network coding can suppress the bandwidth resource consumed by relay transmission, and hence increase the spectral efficiency of cooperative diversity. A distributed strategy of relay selection is applied to the cooperative scheme, which can reduce system overhead and also facilitate the development of the explicit expressions of information metrics, such as outage probability and ergodic capacity. Both analytical and numerical results demonstrate that the proposed protocol can achieve large ergodic capacity and full diversity gain simultaneously.

Early crime writing and the state: Jonathan Wild, Daniel Defoe and Bernard Mandeville in 1720s London

This article argues that the early development of crime writing needs to be understood in relation to the consolidation of the modern state. It demonstrates that London in the 1720s constitutes a significant moment in this early development for three main reasons. First, the period witnessed a crime epidemic which reached its climax in the 1720s and which precipitated a set of particularly aggressive counter-measures by the state; second, it saw the rise and eventual fall of the infamous Jonathan Wild who acted as both thief and surrogate policeman; and third, it was also marked by a surge in interests on the part of writers like Daniel Defoe and Bernard Mandeville in the related matters of crime and punishment. This article explores the ways in which accounts of crime and punishment in this period deployed and in some instances interrogated the rhetoric of social contract theory and writings on statecraft, particularly by Thomas Hobbes and Mandeville. But while the criminal biographies and gallows sermons produced by the Newgate prison’s ‘ordinaries’ provided crude and reductive accounts of the efficacy of the state, the article shows how two accounts of the life of Jonathan Wild (by Defoe and H.D) responded in highly complex ways to the issues of crime and policing and provided a consistently and self-consciously ambivalent reading of the state and state power. To conclude, I suggest that this ambivalence can be read as a critique of the impartial or neutral state and that it constitutes one of the key features of what we would later understand to be crime writing as a dedicated literary genre.

‘Making Older People Equal: Reforming the Law on Access to Education and Other Services’

Age-based discrimination in the supply of goods and services (including educational services) has only very recently been outlawed in the United Kingdom by the Equality Act 2010, the relevant sections of which have not yet been brought into force. This paper critically considers the Act and its implications, as well as the current proposal for an EU Directive on Goods and Services.The greatest immediate potential of the Equality Act lies in the general prohibition against age discrimination and the scope of the exceptions to it. The paper argues that exceptions permitting service providers to discriminate against older people (i.e. negative exceptions) should be very specifically set out in the reforming legislation.There should be no general defence to a claim of age discrimination based around the concept of ‘reasonableness’, which would not be consistently interpreted by courts and tribunals in a way that steers clear of traditional ageist assumptions and stereotyping.The paper argues that service providers should be permitted to discriminate in favour of older people (i.e. make positive exceptions) if the reason for doing do so satisfi es legislative criteria which are designed, amongst other things, to meet the particular needs of older persons or to promote social inclusion. Under this proposal, preferential treatment such as age-related concessionary fees for adult education courses and programmes would be lawful.
