Introduction
Much has been written about the impact of conflict on the physical nature of cities; most obviously perhaps the damage, destruction, defensive construction and spatial reconfigurations that evolve in times of conflict. Set within the context of Belfast, Northern Ireland, this paper will focus on three areas. First, a closer reading of the long-term physical impact of conflict, in particular, the spatial forms and practices that persist conceptually and culturally, and/or resist re-conceptualisation. Secondly, the effect of conflict on the nature of architectural practice itself, considering whether issues such as appointment and procurement impacted on architectural expectation and the context of operation. Thirdly, the effect of conflict on people, in particular in relation to creativity and hence the psyche of practice itself. This section will also identify the conditions that undermine or support design quality and creativity not only within times of conflict but also as society evolves out of the shadow space. 1
Twelve years on from the Peace Agreement,2 it may seem remarkable from an external perspective that Northern Ireland still needs to be reflecting on its troubled past. But the immediate post-conflict phase offered the communities of Northern Ireland place and time to experience ‘normal life’, begin to reconcile themselves to the hurt they experienced and start to reconfigure their relationships to one another. Indeed, it has often been expressed that probing the issues too much, at too early a phase, might in fact ‘Open old wounds without resolving anything’ and/or ‘Destabilise the already fragile political system.’3 This tendency not to deliberate or be too probing is therefore understandable and might be the reason why, for example, Northern Ireland's first Architecture and Built Environment policy, published in June, 2006, contains only one routine reference to ‘the Troubles’.
Clearly, however, there is a time in the development of a healthy, functioning society, when in order effectively to plan its future, it must also carry out a closer reading and deeper understanding of its past. As Maya Angelou puts it, ‘History, despite its wrenching pain/ Cannot be unlived, and if faced/ With courage, need not be lived again.’4
Increasingly, those within the creative arts sector and the built environment professions are showing interest in carrying out that closer reading, teasing out issues around conflict. This was led in part by the recent publication of the Troubles Archive by the Arts Council of Northern Ireland.5 Those involved in the academic or professional development of future generations of architects are also concerned about the relevance of a post-conflict condition. As a profession, if architects purport to be concerned with context, then the almost tangible socio-political circumstances and legacy of Northern Ireland does inevitably require direct eye contact. This paper therefore aims to bring the relationship between conflict and architectural practice in Northern Ireland into sharp focus, not to constrain or dull creative practice but to heighten its potential.

Educating the public accurately about Applied Behavior Analysis (ABA) is an important undertaking, not least because misconceptions and myths about ABA abound. In this paper we argue that, unfortunately, the efforts of many dedicated professionals and parents to disseminate accurate information about the benefits of ABA for children diagnosed with autism spectrum disorder (ASD) are damaged by a few behavior analysts whose focus seems to be more on monetary gains than social responsibility. We cite examples of the resulting harm to the public image of behavior analysis from a number of European countries. We conclude by calling upon fellow scientists to unite in their opposition to unscrupulous abuses of free market forces for short-term monetary gains that damage the dissemination of the science of behavior analysis and thereby ultimately disadvantage those who should benefit primarily from our science, i.e., some of the most vulnerable citizens of society.

The increasing penetration of wind generation on the Island of Ireland has been accompanied by close investigation of low-frequency pulsations contained within active power flow. A primary concern is excitation of low-frequency oscillation modes already present on the system, particularly the 0.75 Hz mode as a consequence of interconnection between the Northern and Southern power system networks. In order to determine whether the prevalence of wind generation has a negative effect (excites modes) or positive impact (damping of modes) on the power system, oscillations must be measured and characterised. Using time – frequency methods, this paper presents work that has been conducted to extract features from low-frequency active power pulsations to determine the composition of oscillatory modes which may impact on dynamic stability. The paper proposes a combined wavelet-Prony method to extract modal components and determine damping factors. The method is exemplified using real data obtained from wind farm measurements.

Context. Hot-Jupiter planets must form at large separations from their host stars where the temperatures are cool enough for their cores to condense. They then migrate inwards to their current observed orbital separations. Different theories of how this migration occurs lead to varying distributions of orbital eccentricity and the alignment between the rotation axis of the star and the orbital axis of the planet. Aims: The spin-orbit alignment of a transiting system is revealed via the Rossiter-McLaughlin effect, which is the anomaly present in the radial velocity measurements of the rotating star during transit due to the planet blocking some of the starlight. In this paper we aim to measure the spin-orbit alignment of the WASP-3 system via a new way of analysing the Rossiter-McLaughlin observations. Methods: We apply a new tomographic method for analysing the time variable asymmetry of stellar line profiles caused by the Rossiter-McLaughlin effect. This new method eliminates the systematic error inherent in previous methods used to analyse the effect. Results: We find a value for the projected stellar spin rate of v sin i = 13.9 ± 0.03 km s-1 which is in agreement with previous measurements but has a much higher precision. The system is found to be well aligned, with ? = 5-5+6° which favours an evolutionary history for WASP-3b involving migration through tidal interactions with a protoplanetary disc. From comparison with isochrones we put an upper limit on the age of the star of 2 Gyr.

Punitive public attitudes cannot be easily explained by pointing to instrumental concerns (e.g., fear of crime, personal victimization, or rea or perceived levels of crime). Instead, numerous observers have suggested that public punitiveness is more a symptom of free-floating anxieties and insecurities resulting from social change than a rational response to crime problems. We argue that these public concerns might be better understood by drawing on the insights of psychoanalytic theory, and we review relevant theoretical work to that effect.

From tackling illicit flows of small arms to combating nuclear smuggling, the shadow trade has become a central target of attempts to control the means of violence. This article argues that much of this practice and literature is framed in unhelpful terms that posit two distinct worlds, an upperworld and underworld, that separates illicit flow networks from the familiar world of state security policy. This implies that the possibilities for controlling the shadow trade are limited or require expansive and expensive controls. The article then examines the formation of illicit flow networks, drawing on examples including narcotics, small arms, nuclear materials, nuclear technology, major conventional arms, dual use technologies, and chemical weapons precursors; and finds that state and hybrid actors rather than extensive private networks are constitutive of illicit networks in many ways. It concludes by reclaiming hope for controlling the means of violence in this hybridity.

In this article, we argue that the history of bail foretells the future of parole. Under a plancalled the Conditional Post-Conviction Release Bond Act (recently passed into law inthree states), US prisoners can secure early release only after posting ‘post-convictionbail’. As with pre-trial bail, the fledgling model would require prisoners to pay a percent-age of the bail amount to secure their release under the contractual responsibility of acommercial bail agency. If release conditions are breached, bounty hunters are legallyempowered to seize and return the parolee to prison. Our inquiry outlines the origins of this post-conviction bond plan and the research upon which it is based. Drawing on the‘new penology’ framework, we identify several underlying factors that make for a ripeadvocacy environment and set the stage for widespread state-level adoption of this planin the near future. Post-conviction bail fits squarely within the growing policy trendstoward privatization, managerialism, and actuarial justice. Most importantly, though,advocates have the benefit of precedent on their side, as most US states have longrelied on a system of commercial bail bonding and private bounty hunting to manageconditional pretrial release.

In this paper we present an empirical analysis of the residential demand for electricity using annual aggregate data at the state level for 48 US states from 1995 to 2007. Earlier literature has examined residential energy consumption at the state level using annual or monthly data, focusing on the variation in price elasticities of demand across states or regions, but has failed to recognize or address two major issues. The first is that, when fitting dynamic panel models, the lagged consumption term in the right-hand side of the demand equation is endogenous. This has resulted in potentially inconsistent estimates of the long-run price elasticity of demand. The second is that energy price is likely mismeasured.
