Reparative Complementarity: Ensuring an Effective Remedy for Victims in the Reparation Regime of the International Criminal Court

This article examines the reparation regime of the International Criminal Court in light of its first reparation decision. Based on the reparation jurisprudence established in international law and human rights law to provide victims of international crimes an effective remedy, this article suggests that in order for the International Criminal Court to achieve this objective it needs to go beyond individual criminal responsibility due to its limitations. This article considers the role of reparative complementarity in ensuring an effective remedy to victims of international crimes as part of the reparation regime of the International Criminal Court.

How to measure the micromaser spectrum in the trapping state regime

We show how our recently proposed scheme for the measurement of the micromaser linewidth, which relates the phase diffusion dynamics of the cavity field to the population statistics of probe atoms, can be applied in the presence of trapping states, where the phase diffusion approximation does not strictly hold. This should allow the observation of the peculiar linewidth oscillations versus atomic pumping which are expected in this regime, and whose origin lies in the quantum nature of the cavity field.

Editorial: Special Issue on Secure Physical Layer Communications

In wireless networks, the broadcast nature of the propagation medium makes the communication process vulnerable to malicious nodes (e.g. eavesdroppers) which are in the coverage area of the transmission. Thus, security issues play a vital role in wireless systems. Traditionally, information security has been addressed in the upper layers (e.g. the network layer) through the design of cryptographic protocols. Cryptography-based security aims to design a protocol such that it is computationally prohibitive for the eavesdropper to decode the information. The idea behind this approach relies on the limited computational power of the eavesdroppers. However, with advances in emerging hardware technologies, achieving secure communications relying on protocol-based mechanisms alone become insufficient. Owing to this fact, a new paradigm of secure communications has been shifted to implement the security at the physical layer. The key principle behind this strategy is to exploit the spatial-temporal characteristics of the wireless channel to guarantee secure data transmission without the need of cryptographic protocols.

Special Education Today in the United Kingdom

This chapter attempts to provide a critical analysis of special needs education within the United Kingdom today. Central to such an analysis is an understanding of the rapidly changing social and political milieu within which special needs education is embedded, including the rapidly changing demographics of schooling, and the devolution of political power into four separate but linked countries - England, Wales, Scotland and Northern Ireland. Following a discussion of such wider social, political and educational issues, the authors thoroughly explore the convergences and divergences in policy and practice across the four devolved administrations. They describe a plethora of contemporary texts within each of the four administrations that speak to the need for special needs education to change in response to 21st century concerns about the problems of access to, and equity in education for all children. Despite this, they explain why they remain circumspect about the potential of such developments to lead to successful inclusive practices and developments on the ground. Their analysis in the last section centres on the issue of teacher education for inclusion and some very innovative UK research and development projects that have been reported to successfully engage teachers with new paradigm thinking and practice in the field of inclusive special needs education.

Successful but Unappealing: Fifteen Years of Workplace Partnership in Ireland:Special Issue: Partnership, Collaboration and Mutual Gains

This paper presents the first comprehensive review and assessment of Ireland's influential 15-year experiment with workplace partnership. The paper reviews the outcomes of workplace partnership and explains the limited adoption of partnership in the private and public sectors, drawing on the authors' experiences as participants in policy initiatives concerned with promoting partnership in the workplace. Although the promotion of partnership was to the fore in public policy between the late 1990s to the onset of the recession and successful outcomes were reported for the main stakeholders where partnerships were established, the paper explains why the concept nevertheless remained largely unappealing across the private and public sectors.

Navigating Risk: Understanding the Impact of the Conflict on Children and Young People in Northern Ireland:Special Issue: Northern Ireland: 20 Years After the Cease-Fires

Twenty years on from the 1994 cease-fires, Northern Ireland is a markedly safer place for children and young people to grow up. However, for a significant number, growing up in post-conflict Northern Ireland has brought with it continued risks and high levels of marginalization. Many young people growing up on the sharp edge of the transition have continued to experience troubling levels of poverty, lower educational attainment, poor standards of childhood health, and sustained exposure to risk-laden environments. Reflecting on interdisciplinary research carried out since the start of the “transition” to peace, this article emphasizes the impact that embedded structural inequalities continue to have on the social, physical, mental, and emotional well-being of many children and young people. In shining a light on the enduring legacy of the conflict, this article moves to argue that greater attention needs to be given to the ongoing socioeconomic factors that result in limited lifetime opportunities, marginalization, and sustained poverty for many young people growing up in “peacetime” Northern Ireland.

Enhanced proton beam collimation in the ultra-intense short pulse regime

The collimation of proton beams accelerated during ultra-intense laser irradiation of thin aluminum foils was measured experimentally whilst varying laser contrast. Increasing the laser contrast using a double plasma mirror system resulted in a marked decrease in proton beam divergence (20° to <10°), and the enhanced collimation persisted over a wide range of target thicknesses (50 nm–6 µm), with an increased flux towards thinner targets. Supported by numerical simulation, the larger beam divergence at low contrast is attributed to the presence of a significant plasma scale length on the target front surface. This alters the fast electron generation and injection into the target, affecting the resultant sheath distribution and dynamics at the rear target surface. This result demonstrates that careful control of the laser contrast will be important for future laser-driven ion applications in which control of beam divergence is crucial.

Two-Way Relaying under the Presence of Relay Transceiver Hardware Impairments

Hardware impairments in physical transceivers are known to have a deleterious effect on communication systems; however, very few contributions have investigated their impact on relaying. This paper quantifies the impact of transceiver impairments in a two-way amplify-and-forward configuration. More specifically, the effective signal-to-noise-and-distortion ratios at both transmitter nodes are obtained. These are used to deduce exact and asymptotic closed-form expressions for the outage probabilities (OPs), as well as tractable formulations for the symbol error rates (SERs). It is explicitly shown that non-zero lower bounds on the OP and SER exist in the high-power regime---this stands in contrast to the special case of ideal hardware, where the OP and SER go asymptotically to zero.

Harmonic generation by noble-gas atoms in the near-IR regime using ab initio time-dependent R-matrix theory

We demonstrate the capability of ab initio time-dependent R-matrix theory to obtain accurate harmonic generation spectra of noble-gas atoms at near-IR wavelengths between 1200 and 1800 nm and peak intensities up to 1.8 × 10^(14) W/cm^(2). To accommodate the excursion length of the ejected electron, we use an angular-momentum expansion up to Lmax=279. The harmonic spectra show evidence of atomic structure through the presence of a Cooper minimum in harmonic generation for Kr, and of multielectron interaction through the giant resonance for Xe. The theoretical spectra agree well with those obtained experimentally.
