Contact and Culture: Mechanisms of Reconciliation in Northern Ireland and Israel

In Northern Ireland and Israel schools have long been recognised as key sites for addressing the problems of poor intergroup relations (see Dunn, 1990; Murray, 1985). The developments of integrated schools which welcome members of the main communities have been regarded as a key development which is likely to be instrumental in promoting more harmonious relations. Although the schools have been regarded in the media as a ‘good news story’ the qualitative processes through which teachers within these schools foster reconciliation is not always clear. The purpose of this chapter is thus to explore this question by drawing on contact theory and interviews with teachers in Northern Ireland and Israel.

Output Additionality of Public Support for Innovation: Evidence for Irish Manufacturing Plants

Public support for private R&D and innovation is part of most national and regional innovation support regimes. In this article, we estimate the effect of public innovation support on innovation outputs in Ireland and Northern Ireland. Three dimensions of output additionality are considered: extensive additionality, in which public support encourages a larger proportion of the population of firms to innovate; improved product additionality, in which there is an increase in the average importance of incremental innovation; new product additionality, in which there is an increase in the average importance of more radical innovation. Using an instrumental variable approach, our results are generally positive, with public support for innovation having positive, and generally significant, extensive, improved and new product additionality effects. These results hold both for all plants and indigenously owned plants, a specific target of policy in both jurisdictions. The suggestion is that grant aid to firms can be effective in both encouraging firms to initiate new innovation and improve the quality and sophistication of their innovation activity. Our results also emphasize the importance for innovation of in-house R&D, supply-chain linkages, skill levels and capital investment, all of which may be the focus of complementary policy initiatives.

Bandas de sopro – um diálogo transcultural

Brass bands are among the most widespread instrumental ensembles in the world, yet there has been little academic interest in them. This is because they stand in a space between art and authenticity, as their repertoires are thought to lack artistic merit while their military legacies have disconnected them from the ‘authentic’ music of ‘the people’. This paper aims to show how it is precisely this intermediary position which has attracted the attention of some (ethno)musicologists, and a growing number of studies demonstrate the analytic potential of this musical universe in a wide range of contexts across the globe.

Digital Musical Interactions: Performer-System Relationships and their Perception by Spectators

This article adopts an ecological view of digital musical interactions, first considering the relationship between performers and digital systems, and then spectators’ perception of these interactions. We provide evidence that the relationships between performers and digital music systems are not necessarily instrumental in the same was as they are with acoustic systems, and nor should they always strive to be. Furthermore, we report results of a study suggesting that spectators may not perceive such interactions in the same way as performances with musical instruments. We present implications for the design of digital musical interactions, suggesting that designers should embrace the reality that digital systems are malleable and dynamic, and may engage performers and spectators in different modalities, sometimes simultaneously.

RNA polymerase I-specific subunits promote polymerase clustering to enhance the rRNA gene transcription cycle.

RNA polymerase I (Pol I) produces large ribosomal RNAs (rRNAs). In this study, we show that the Rpa49 and Rpa34 Pol I subunits, which do not have counterparts in Pol II and Pol III complexes, are functionally conserved using heterospecific complementation of the human and Schizosaccharomyces pombe orthologues in Saccharomyces cerevisiae. Deletion of RPA49 leads to the disappearance of nucleolar structure, but nucleolar assembly can be restored by decreasing ribosomal gene copy number from 190 to 25. Statistical analysis of Miller spreads in the absence of Rpa49 demonstrates a fourfold decrease in Pol I loading rate per gene and decreased contact between adjacent Pol I complexes. Therefore, the Rpa34 and Rpa49 Pol I–specific subunits are essential for nucleolar assembly and for the high polymerase loading rate associated with frequent contact between adjacent enzymes. Together our data suggest that localized rRNA production results in spatially constrained rRNA production, which is instrumental for nucleolar assembly.

Disowning our shadow: a psychoanalytic approach to understanding punitive public attitudes

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.

Living through the death of a child: A qualitative study of bereaved parents’ experiences

Design: Cross-sectional qualitative study.

Data sources: Interviews with purposeful sample of 25 recently bereaved parents.

Methods: Semi-structured in-depth interviews.

Results: Four analytically distinct processes were identified in the responses of parents to the death of a child. These are referred to as ‘piloting’, ‘providing’, ‘protecting’ and ‘preserving’. Regardless of individual circumstances, these processes were integral to all parents’ coping, enabling an active ‘doing’ for their child and family throughout the trajectory of their child's illness and into bereavement.

Conclusions: Facilitating the capacity of parents to ‘do’ is central to coping with the stress and uncertainty of living through the death of a child. The provision of informational, instrumental and emotional support by health care professionals in the context of ‘doing’ is core to quality palliative care.

Keywords: Bereaved parents; Cancer; Dying child; End-of-life; Palliative care; Non-malignant

Novel Inhibitors of the Pseudomonas aeruginosa Virulence Factor LasB: a Potential Therapeutic Approach for the Attenuation of Virulence Mechanisms in Pseudomonal Infection

Pseudomonas elastase (LasB), a metalloprotease virulence factor, is known to play a pivotal role in pseudomonal infection. LasB is secreted at the site of infection, where it exerts a proteolytic action that spans from broad tissue destruction to subtle action on components of the host immune system. The former enhances invasiveness by liberating nutrients for continued growth, while the latter exerts an immunomodulatory effect, manipulating the normal immune response. In addition to the extracellular effects of secreted LasB, it also acts within the bacterial cell to trigger the intracellular pathway that initiates growth as a bacterial bio?lm. The key role of LasB in pseudomonal virulence makes it a potential target for the development of an inhibitor as an antimicrobial agent. The concept of inhibition of virulence is a recently established antimicrobial strategy, and such agents have been termed “second-generation” antibiotics. This approach holds promise in that it seeks to attenuate virulence processes without bactericidal action and, hence, without selection pressure for the emergence of resistant strains. A potent inhibitor of LasB,N-mercaptoacetyl-Phe-Tyr-amide (Ki 41 nM) has been developed, and its ability to block these virulence processes has been assessed. It has been demonstrated that thes compound can completely block the action of LasB on protein targets that are instrumental in bio?lm formation and immunomodulation. The novel LasB inhibitor has also been employed in bacterial-cell-based assays, to reduce the growth of pseudomonal bio?lms, and to eradicate bio?lm completely when used in combination with conventional antibiotics.

A Computer Music Retrospective

A composer who has worked in the field of computer music for the last 25 years reflects on how technological developments during that time have affected his work in computer music, instrumental music and hybrid combinations of the two. The compositional trajectories traced here often run parallel to opportunities afforded by the evolution of computer technology suitable for the generation of digital audio.

Photometric observations of the Type Ia SN 2002er in UGC 10743

Extensive light and colour curves for the Type Ia supernova (SN Ia) SN 2002er are presented as part of the European Supernova Collaboration. We have collected UBVRI photometry from 11 different telescopes covering the phases from 7 d before until 619 d after maximum light. Corrections for the different instrumental systems and the non-thermal spectrum of the supernova (S-corrections) have been applied. With the densely sampled light curves we can make detailed comparisons to other well-observed objects. SN 2002er most closely resembles SN 1996X after maximum, but clearly shows a different colour evolution before peak light and a stronger shoulder in V and R bands compared to other well-observed SNe Ia. In particular, the rise time appears to be longer than what is expected from the rise time versus decline rate relation. We use several methods to determine the reddening towards SN 2002er based on the colour evolution at near peak and at late phases. The uvoir (bolometric) light curve shows great similarity with SN 1996X, but also indications of a higher luminosity, longer rise time and a more pronounced shoulder 25 d past maximum. The interpretation of the light curves was carried out with two independent light curve codes. Both find that given the luminosity of SN 2002er the Ni-56 mass exceeds 0.6 M-circle dot with preferred values near 0.7 M-circle dot. Uncertainties in the exact distance to SN 2002er are the most serious limitation of this measurement. The light-curve modelling also indicates a high level of mixing of the nickel in the explosion of SN 2002er.

Exoplanets or Dynamic Atmospheres? The Radial Velocity and Line Shape Variations of 51 Pegasi and tau Bootis

The stars 51 Pegasi and tau Bootis show radial velocity variations that have been interpreted as resulting from companions with roughly Jovian mass and orbital periods of a few days. Gray and Gray & Hatzes reported that the radial velocity signal of 51 Peg is synchronous with variations in the shape of the line lambda 6253 Fe I; thus, they argue that the velocity signal arises not from a companion of planetary mass but from dynamic processes in the atmosphere of the star, possibly nonradial pulsations. Here we seek confirming evidence for line shape or strength variations in both 51 Peg and tau Boo, using R = 50,000 observations taken with the Advanced Fiber Optic Echelle. Because of our relatively low spectral resolution, we compare our observations with Gray's line bisector data by fitting observed line profiles to an expansion in terms of orthogonal (Hermite) functions. To obtain an accurate comparison, we model the emergent line profiles from rotating and pulsating stars, taking the instrumental point-spread function into account. We describe this modeling process in detail. We find no evidence for line profile or strength variations at the radial velocity period in either 51 Peg or in tau Boo. For 51 Peg, our upper limit for line shape variations with 4.23 day periodicity is small enough to exclude with 10 sigma confidence the bisector curvature signal reported by Gray & Hatzes; the bisector span and relative line depth signals reported by Gray are also not seen, but in this case with marginal (2 sigma ) confidence. We cannot, however, exclude pulsations as the source of 51 Peg's radial velocity variation because our models imply that line shape variations associated with pulsations should be much smaller than those computed by Gray & Hatzes; these smaller signals are below the detection limits both for Gray & Hatzes's data and for our own. tau Boo's large radial velocity amplitude and v sin i make it easier to test for pulsations in this star. Again we find no evidence for periodic line shape changes, at a level that rules out pulsations as the source of the radial velocity variability. We conclude that the planet hypothesis remains the most likely explanation for the existing data.

Veblen's Placebo: A historical perspective on administrative evil

Thorstein Veblen was a turn of the 20th century American economist concerned with the implications of financial capitalists directing the means of production. Veblen proposed that the rationality of "material science" as practiced by the "production engineers" is fundamentally different from the rationality of market capitalism. If this claim is valid, our previous contentions regarding accounting, as a facilitating technology, for administrative evil warrant reconsideration. Veblen's position provides a historical perspective on one dimension of administrative evil that is generally unquestionably accepted, especially within accounting. That is, technology, such as accounting and the related information systems, is amoral, and it is only through ideologically instigated applications that any moral value accrues. We discuss administrative evil and the role of instrumental rationality generally, and accounting specifically, in creating it. Veblen's characterization of financial capitalism and production engineers and his arguments for the primacy of economic efficiency versus "pecuniary gain" provide a basis for evaluating the legitimating action. We consider how Veblen's work relates to notions of instrumental rationality and then undertake a critical assessment of the ideas. Some of Veblen's ideas, while utopian, might be seen as an elixir for the detrimental influences of financial capital; however, at best, they provide a placebo for the ills of administrative evil and, as such, do not provide an amoral basis for legitimating the associated accounting systems.

Toenail trace element status and risk of Barrett's oesophagus and oesophageal adenocarcinoma. Results from the FINBAR study

Trace elements have been cited as both inhibitory and causative agents of cancer but importantly exposure to them is potentially modifiable. Our study aimed to examine toenail trace element status and risk of Barrett's oesophagus (BO) and oesophageal adenocarcinoma (OAC). Toenail clippings from each hallux were obtained from 638 participants of the FINBAR (Factors Influencing the Barrett's Adenocarcinoma Relationship) study comprising 221 healthy controls, 98 reflux oesophagitis, 182 BO and 137 OAC cases. The concentrations of eight toenail trace elements were determined using instrumental neutron activation analysis. Using multivariable adjusted logistic regression analysis, odds ratios (OR) and 95% confidence intervals (CIs) were calculated within tertiles of trace element concentrations. A twofold increased risk of BO was observed, but not OAC, among individuals in the highest tertile of toenail zinc status OR 2.21 (95% CI, 1.11-4.40). A higher toenail selenium status was not associated with risk of OAC OR 0.94 (95% CI, 0.44-2.04) or BO OR 0.89 (95% CI, 0.37-2.12). A borderline significant increased risk of BO was detected with a higher toenail cobalt concentration, OR 1.97 (95% CI, 1.01-3.85). No association was found between toenail levels of chromium, cerium, mercury and OAC or BO risk. This is the first case-control study to investigate a variety of trace elements in relation to OAC and BO risk. Despite antioxidant and proapoptotic properties, no associations were found with selenium. Higher concentrations of toenail zinc and cobalt were associated with an increased BO risk, but not OAC. These findings need confirmation in prospective analysis.

Semiotics, Presence and the Sublime in the Work of Alvin Lucier

Alvin Lucier, in his uncompromising exploration into the artistic potential of acoustic phenomena, has developed a body of work that remains highly original and hugely influential across many disciplines. His seminal works such as I am sitting in a room and Music for Solo Performer foreshadowed ways of approaching sound that are in common use among electro-acoustic composers, installation artists, as well as in commercial products. Lucier, despite his far reaching influence, is and has always been a composer, and his explorations of acoustics have been singularly focused on the development of a rich body of music. In this article, I investigate Lucier’s unique approach and attitude towards acoustics and aspire to enumerate important aesthetic developments he has made in creating music through the exploration of acoustic phenomena. In particular, this article seeks to investigate the role of semiotics in Lucier’s work, commenting on the pre-linguistic nature of Lucier’s approach to acoustic phenomenon. Here as well, an exploration of Lucier’s musical materials takes place, focusing on his instrumental compositions, specifically Diamonds for One, Two or Three Orchestras, where instruments are used as catalysts to generate in real-time acoustic phenomenon which interact to produce a rich yet intimate world of sound. Finally, Lucier’s approach to semiotics and real-time generation of music is viewed through a sublime aesthetic provoking questions regarding issues of presence and the now.

Assessing the determinants of public confidence in the police: A case study of a post-conflict community in Northern Ireland

Drawing upon original survey research this article seeks to identify the generative processes that influence perceptions of the police in the context of an inner-city neighbourhood in Northern Ireland that has been affected by increases in crime and disorder in the aftermath of the peace process. Conceptually we draw upon recent research from England and Wales that outlines confidence in the police in terms of instrumental and expressive dimensions. We apply this framework and consider whether it provides a useful template for understanding the post-conflict dynamics of police-community relations in our study area. Contrary to much received wisdom our analysis suggests that instrumental concerns about crime and illegal activity are a more influential predictor of attitudes to the police than expressive concerns with disorder and anti-social behaviour. Consequently our discussion points to the variance in local and national survey data and questions the degree to which the latter can usefully inform our understanding of trends and developments in discrete micro-spaces. Our conclusion outlines the potential policy implications for state policing practice in deprived urban spaces.
