Gazing at Ground Zero: Tourism, Voyeurism and Spectacle

This essay uses the temporary viewing platform at the site of the former World Trade Center to explore our fascination with violence, conflict and disaster. It illustrates how discourses of voyeurism and authenticity promote a desire for sites of horror, and examines how that desire both disrupts and reinforces our prevailing interpretations of global politics. The viewing platform at Ground Zero was initially constructed to manage the thousands of people who traveled to New York in response to the shocking media images of 11 September. However, their desire to escape mediation and touch "the real" had the opposite effect - it transformed Ground Zero into a tourist attraction. Using Ground Zero as a starting point, this essay theorizes discourses of voyeurism and authenticity through the work of Baudrillard, Debord and Bauman in an effort to position the tourist as a significant political subject.

Neural network based control for synchronous generators

In this paper, a Radial Basis Function neural network based AVR is proposed. A control strategy which generates local linear models from a global neural model on-line is used to derive controller feedback gains based on the Generalised Minimum Variance technique. Testing is carried out on a micromachine system which enables evaluation of practical implementation of the scheme. Constraints imposed by gathering training data, computational load, and memory requirements for the training algorithm are addressed.

Durability of Self-Compacting Concrete

Because of the different mix design in comparison with traditional concrete and the absence of vibration, different durability characteristics might be expected for self-compacting concrete. The stateof- the-art report, prepared by RILEM Technical Committee TC 205-DSC focuses on the Durability of SCC, by first gathering the available information concerning pore structure, air-void system and transport mechanisms. The available durability results are studied and summarised keeping in mind the fundamental mechanisms and driving forces. All relevant durability issues are considered, like carbonation, chloride penetration, frost resistance, ASR, sulphate attack, thaumasite formation, fire resistance, etc... It is not the intention to give a review on these durability aspects for concrete in general. The aim however is to point at the specifics related to the use of SCC, e.g. due to the addition of a large amount of limestone filler, etc... This paper summarizes the main conclusions of the State-of-the-Art Report.

Signal residuals and hermit crab displays: flaunt it if you have it!

In animal contests selection should favour information gathering regarding the likely costs and benefits of continued conflict, and displays may provide a means for contestants to gain information about the fighting ability or aggressive intent of competitors. However, there is debate over the reliability of such displays and low levels of deception may occur within otherwise honest signalling systems. Hermit crabs use displays involving the chelipeds during agonistic encounters. We examined how variation in chelae size in relation to body size, a determinant of fighting ability, affects their use in displays and the process and outcome of contests over gastropod shells. In accordance with deceptive use of an otherwise honest signal, we found that contestants with large chelipeds for their body size spent more time performing the cheliped presentation display. Moreover, cheliped residuals and displays influenced the escalation level of encounters. There was a positive association between cheliped displays and the occurrence of 'grappling', but a negative association between displays and the occurrence of shell fights, suggesting that displays may signal aggressive intent and a reluctance to back off or accept the more passive defender role in a fight. Furthermore, the smaller of the two contestants in shell fights had larger cheliped residuals compared to those smaller contestants not involved in shell fights, which is consistent with disrupted opponent assessment. This study adds to mounting evidence that when acting as a signaller, individuals for whom the display exaggerates competitive ability attempt to manipulate opponents, using the display more often.

Assessment of fighting ability in animal contests

Selection should favour accurate information gathering regarding the likely costs and benefits of continued conflict. Here we consider how variation in the abilities of contestants to assess resource-holding potential (RHP) influences fights. This has been examined in various game theory models. However, discriminating between assessment strategies has proven difficult and has resulted in confusion. To add clarity, we group existing models into three main types that differ in the information about RHP that contestants are presumed to gather: (1) pure self-assessment, (2) cumulative assessment and (3) mutual assessment. Within this framework we outline methods advocated to discriminate successfully between the three main assessment models. We discuss support for each model, before highlighting a number of conflicting and inconclusive studies, leading us to consider alternative approaches to investigate assessment. Furthermore, we examine support for newly emerging concepts such as 'varying degrees of assessment', 'switching assessment' strategies and the possibility of contestants adopting different assessment strategies within a fight involving distinctive roles. We suggest future studies will benefit by judicious use of a battery of techniques to determine how animals settle contests. Finally, we highlight difficulties with current game theory models, and raise concerns regarding the use of certain behavioural criteria to accept or reject a model, particularly since this may conflict with evidence for a given assessment strategy. Furthermore, the failure of existing models to account for newly emerging concepts points to limitations of their use and leads us to challenge game theoreticians to develop upon them.

"All Have to Live in Me...": A Study of the Use of English Alongside Other African Languages in a Kenyan School

The purpose of this paper, which builds on an earlier paper published in this Journal (Vol. 20, No. 6), is to develop the discussion around how English has been taught, used and perceived in Kenya, using data gathered from a small second-level English-medium school in Kenya. The complex relationships between language and identity are at work in the everyday routines of both staff and pupils within such a context. The paper seeks to set out a clear methodology for gathering data which could help describe these relationships with more clarity while also subjecting the data to analysis informed by the growing body of research and theory that focuses on language policy in post-colonial and neo-colonial settings. Finally, these pieces of data are used as the basis of a further exploration of the implications for classroom practice in teaching English in this environment.

Crystal Creatures: Context for the Dublin Blaschka Congress

The ‘Dublin Blaschka Congress’ was conceived as a gathering to bring together the diverse scholarly disciplines that are uniquely, if eccentrically, joined in the study of scientific glass models. Leopold and Rudolf Blaschka are best known for the ‘Glass Flowers’ of Harvard but in the nineteenth century they also invented techniques to sculpt anatomically accurate marine invertebrates in glass. In the course of preparing the Congress and a coordinated temporary exhibition, much new information was uncovered about the collections of Blaschka objects in Ireland, including a total of nearly 800 surviving models. The history of the artists shows a clever business model that was designed to tap a niche market in the contemporary fascination with natural history, and improved through the course of several decades with input from clients and their own passion for understanding their biological subjects. From a modern perspective, a single Blaschka glass model of a marine invertebrate can embody biology, the history of science, craftsmanship, glass chemistry, aesthetics and art. This ability to cross interdisciplinary bridges is a singular strength of the Blaschka works, and is evident in the published proceedings of the Congress.

Vascular stem cells and ischaemic retinopathies

Retinal ischaemic disorders such as diabetic retinopathy and retinal vein occlusion are common. The hypoxia-related stimuli from oxygen-deprived neural and glial networks can drive expression of growth factors and cytokines which induce leakage from the surviving vasculature and/or pre-retinal and papillary neovascularisation. If left untreated, retinal vascular stasis, hypoxia or ischaemia can lead to macular oedema or fibro-vascular scar formation which are associated with severe visual impairment, and even blindness. Current therapies for ischaemic retinopathies include laser photocoagulation, injection of corticosteroids or VEGF-antibodies and vitreoretinal surgery, however they carry significant side effects. As an alternative approach, we propose that if reparative intra-retinal angiogenesis can be harnessed at the appropriate stage, ischaemia could be contained or reversed. This review provides evidence that reperfusion of ischaemic retina and suppression of sight-threatening sequelae is possible in both experimental and clinical settings. In particular, there is emphasis on the clinical potential for endothelial progenitor cells (EPCs) to promote vascular repair and reversal of ischaemic injury in various tissues including retina. Gathering evidence from an extensive published literature, we outline the molecular and phenotypic nature of EPCs, how they are altered in disease and provide a rationale for harnessing the vascular reparative properties of various cell sub-types. When some of the remaining questions surrounding the clinical use of EPCs are addressed, they may provide an exciting new therapeutic option for treating ischaemic retinopathies.

Integrated care: utilisation of complementary and alternative medicine within a conventional cancer treatment centre

Objectives: To estimate the proportion of cancer outpatients who visit a Complementary and Alternative Medicine (CAM) unit that is located within a conventional cancer treatment centre; to compare the characteristics of CAM unit visitors with those of all outpatients; to monitor the demand for 20 CAM therapies delivered by professionals, and the use of the CAM unit for waiting, gathering information and informal support from volunteer staff.

Design: Prospective, observational, over a six month period.

Setting: CAM unit within a NHS cancer treatment centre.

Main outcome measures: Utilisation of the CAM unit for 20 complementary therapies, and for waiting, gathering information, informal support; characteristics of CAM users compared with those of all cancer outpatients attending the cancer centre; predictors of CAM therapy use and frequent use.

Results: 761 (95% of those approached) people were recruited, 498 (65.4%) cancer patients, 202 (26.5%) relatives, 37 (4.8%) friends/carers, 24 (3.2%) staff. Women predominated (n = 560, 73.6%). Of all outpatients attending the cancer centre, 498 (15.8%) visited the CAM unit, 290 (9.2%) accessed therapies. Compared to all outpatients, those visiting the CAM unit were: younger (mean 63.7 vs. 58.4 years), more likely to be female (57.9% vs. 78.7%), have breast (14.8% vs. 51.9%), gynaecological (5.0% vs. 9.1%) cancer, live in local postal district (57.3% vs. 61.6%). Significant predictors of therapy use and frequent visits were being a patient, female, higher education, living closer to the cancer centre.

Conclusions: Despite easy access to CAM therapies, a relatively small number of people regularly used them, whilst a larger number selectively tried a few. The integrated CAM unit meets a demand for information and informal support. The findings inform emerging policy on integrating CAM and conventional cancer treatment to address psychosocial needs of people with cancer. More research is needed on why people do not use integrated CAM services and how charges affect demand. © 2008.

Children’s perceptions of primary science assessment in England and Wales

This study builds on and contributes to work on assessment of children in primary school, particularly in science. Previous research has examined primary science assessment from different standpoints, but no studies have speci?cally addressed children’s perspectives. This article provides additional insight into issues surrounding children’s assessment in primary school and how the assessment of science might develop in England after the science SATs (Standard Assessment Tests) were abolished in 2009. Some research suggests that primary science assessment via SATs is a major reason for the observed decline in children’s engagement with science in upper primary and lower secondary school. The analytic focus on engaging children as coresearchers to assist in the process of gathering informed views and interpreting ?ndings from a large sample of children’s views enables another contribution. The study, based on a survey of 1000 children in primary and secondary schools in England and Wales, reveals that despite being assessed under two different regimes (high-stakes national tests in England and moderated teacher assessment in Wales), children’s views of science assessment are remarkably consistent. Most appreciate the usefulness of science assessment and value frequent, non-SATs testing for monitoring/improving science progress. There was a largely negative impact, however, of science
assessment on children’s well-being, particularly due to stress. The paper demonstrates that children provide an important perspective on assessment and that including their views can improve policy-making in relation to primary science assessment.

ASSESSMENTS AND DECISIONS IN METELLINA-SEGMENTATA (ARANEAE, METIDAE) - EVIDENCE OF A PHEROMONE INVOLVED IN MATE GUARDING

Assessments and decision-making underlying the initiation of mate guarding in a common web-building spider, Metellina segmentata, are examined in a series of field and laboratory studies. Adult males do not build webs but wander in search of females and mating opportunities. Adult males then wait at the edge of the webs of females and guard them prior to courtship and mating. Guarded females were heavier, larger and carried more mature eggs than solitary females. An active process of information gathering is apparent from introductions of males to the webs of females. Males make accurate assessments about female quality, even in the absence of the resident female. Cues involving web architecture are not used. Males may assess pheromonal cues on the web of the female in deciding whether to guard or abandon a female.

Managing Cultural Diversity in Healthcare Partnerships: The Case of LIFT

Purpose: The National Health Service (NHS) Local Improvement Finance Trust (LIFT) programme was launched in 2001 as an innovative public-private partnership to address the historical under-investment in local primary care facilities in England. The organisations from the public and private sector that comprise a local LIFT partnership each have their own distinctive norms of behaviour and acceptable working practices - ultimately different organisational cultures. The purpose of this article is to assess the role of organisational culture in facilitating (or impeding) LIFT partnerships and to contribute to an understanding of how cultural diversity in public-private partnerships is managed at the local level. Design/methodology/approach: The approach taken was qualitative case studies, with data gathering comprising interviews and a review of background documentation in three LIFT companies purposefully sampled to represent a range of background factors. Elite interviews were also conducted with senior policy makers responsible for implementing LIFT policy at the national level. Findings: Interpreting the data against a conceptual framework designed to assess approaches to managing strategic alliances, the authors identified a number of key differences in the values, working practices and cultures in public and private organisations that influenced the quality of joint working. On the whole, however, partners in the three LIFT companies appeared to be working well together, with neither side dominating the development of strategy. Differences in culture were being managed and accommodated as partnerships matured. Research limitations/implications: As LIFT develops and becomes the primary source of investment for managing, developing and channelling funding into regenerating the primary care infrastructure, further longitudinal work might examine how ongoing partnerships are working, and how changes in the cultures of public and private partners impact upon wider relationships within local health economies and shape the delivery of patient care. Originality/value: To the authors' knowledge this is the first study of the role of culture in mediating LIFT partnerships and the findings add to the evidence on public-private partnerships in the NHS

Post-conflict Belfast sliced and diced:the case of the Gaeltacht Quarter

This paper considers the recent proliferation of Belfast‘s =Quarters‘ as part of global trends towards the theming of city space, and as a response to the particular situation of Belfast at the beginning of the twenty-first century. It focuses on the Gaeltacht Quarter, a site that exemplifies the difficulty of applying the internationally popular model of cultural difference as a resource for the production of tourist revenue to the context of contested cities. The =quartering‘ of Belfast is represented as a response to post-industrial and post-conflict predicaments this city shares with many others. I consider how the urban context is sometimes exploited, as in exhortations to investors and tourists to contribute to Belfast‘s transformation from =a city of two halves‘ to =a city of seven quarters‘, and sometimes obscured, as in the recent re-invention of the Quarters as remnants of the city‘s distant past.
