This article explores the nature and extent of racist harassment in predominantly white areas. It is based upon a case study of Northern Ireland and draws upon data from indepth interviews with a total of 32 children and 43 parents drawn from the four largest minority ethnic groups in the region: Chinese, Irish Travellers, South Asians and Black Africans. The article demonstrates that racist harassment is a significant problem in schools in Northern Ireland and highlights the varied forms that it can take from overt acts of physical and verbal abuse to more covert and subtle forms of teasing and 'friendly' banter. Following a consideration of the differing responses that schools have made to racist incidents reported to them by children and/or parents, the article concludes by considering the implications of the findings and re-affirming the argument that anti-racist strategies are as relevant and necessary for schools in predominantly white regions as they are in multi-ethnic areas.

Reaching to interact with an object requires a compromise between the speed of the limb movement and the required end-point accuracy. The time it takes one hand to move to a target in a simple aiming task can be predicted reliably from Fitts' law, which states that movement time is a function of a combined measure of amplitude and accuracy constraints (the index of difficulty, ID). It has been assumed previously that Fitts' law is violated in bimanual aiming movements to targets of unequal ID. We present data from two experiments to show that this assumption is incorrect: if the attention demands of a bimanual aiming task are constant then the movements are well described by a Fitts' law relationship. Movement time therefore depends not only on ID but on other task conditions, which is a basic feature of Fitts' law. In a third experiment we show that eye movements are an important determinant of the attention demands in a bimanual aiming task. The results from the third experiment extend the findings of the first two experiments and show that bimanual aiming often relies on the strategic co-ordination of separate actions into a seamless behaviour. A number of the task specific strategies employed by the adult human nervous system were elucidated in the third experiment. The general strategic pattern observed in the hand trajectories was reflected by the pattern of eye movements recorded during the experiment. The results from all three experiments demonstrate that eye movements must be considered as an important constraint in bimanual aiming tasks.

Objectives: The requirement in Northern Ireland to prescribe biologic agents according to NICE/BSR guidelines and within a fixed budget has created a waiting list for treatment that has no parallel in the Republic of Ireland. The study investigated the bearing this situation may have on had on the consultants’ judgements in the respective areas.

Methods: 78 case vignettes created from the data on real patients with RA treated with biologics in the north and south of Ireland were appraised by 9 southern and 8 northern consultants who judged the clinical benefit and significance of the patients’ condition after a trial of therapy. Quantitative (Clinical Judgement Analysis) and Qualitative (Focus groups) techniques were used.

Results: Northern consultants perceived a slightly greater degree of clinical benefit after a trial of therapy than southern consultants. Judgment models of northern and southern consultants were broadly comparable. The latter tended to be more uniform in their judgments than the southern group. Focus group discussions with consultants largely validated the findings of the quantitative analysis but revealed how clinical judgment analysis might be misled by gaming strategies.

Conclusions: Despite the absence of overt rationing in the south of Ireland, as far as the judgment of therapeutic benefit from biologics was concerned, the clinical judgment policies of practitioners were very similar to those in the north. The adoption of NICE/BSR guidelines in the north may have improved the uniformity of clinical practice in Northern Ireland.

This article provides a case study demonstrating the active role that 5- to 6-year-old boys in an English inner-city, multi-ethnic primary school play in the appropriation and reproduction of their masculine identities. It is argued that the emphasis on physicality, violence and racism found among the boys cannot be understood without reference to the immediate contexts of the local community and the school within which they are located. In making this argument the article draws upon and applies the concept of the habitus and develops this with the notion of 'distributed cognition' as proposed in sociocultural theory. Some of the implications of this analysis for working with boys in early years settings are discussed in the conclusion.

This essay seeks to contextualise the intelligence work of the Royal Irish Constabulary, particularly in the 1880s, in terms of the wider British and imperial practice and, as a corollary, to reflect upon aspects of the structure of the state apparatus and the state archive in Ireland since the Union. The author contrasts Irish and British police and bureaucratic work and suggests parallels between Ireland and other imperial locations, especially India. This paper also defines the narrowly political, indeed partisan, uses to which this intelligence was put, particularly during the Special Commission of 1888 on 'Parnellism and crime', when governmentheld police records were made available to counsel for The Times. By reflecting on the structure of the state apparatus and its use in this instance, the author aims to further the debate on the governance of nineteenth-century Ireland and to explore issues of colonial identity and practice. The line of argument proposed in this essay is prefigured in Margaret O'Callaghan, British high politics and a nationalist Ireland: criminality, land and the law under Forster and Balfour (Cork, 199

Alasdair MacIntyre condemns modern politics, specifically liberalism and the institutions of the liberal state, as irredeemably fallen. His core argument is that the liberal state encourages a disempowering ‘compartmentalization’ of people’s everyday roles and activities that undermines the intersubjective conditions of human flourishing. MacIntyre’s alternative is an Aristotelian politics centred on the notion of “practice.” Defined by justice and solidarity, this politics can only be realized, he claims, within local communities which oppose and resist the dictates of the administrative state and capitalist market. Here it is argued that MacIntyre’s notion of “practice” represents a compelling ethical-political ideal. However, the belief that this ideal is best realized within local communities is rejected. In privileging local community, MacIntyre relies on a reductive view of modern states and overlooks the institutional conditions of a just polity. Against this, it is argued that a politics of human flourishing cannot succeed without an emancipatory transformation of large-scale, trans-communal institutions, in particular the state.

Bacterial infection primarily with Staphylococcus spp. and Propionibacterium acnes remains a significant complication following total hip replacement. In this in vitro study, we investigated the efficacy of gentamicin loading of bone cement and pre- and postoperative administration of cefuroxime in the prevention of biofilm formation by clinical isolates. High and low initial inocula, representative of the number of bacteria that may be present at the operative site as a result of overt infection and skin contamination, respectively, were used. When a high initial inoculum was used, gentamicin loading of the cement did not prevent biofilm formation by the 10 Staphylococcus spp. and the 10 P. acnes isolates tested. Similarly, the use of cefuroxime in the fluid phase with gentamicin-loaded cement did not prevent biofilm formation by four Staphylococcus spp. and four P. acnes isolates tested. However, when a low bacterial inoculum was used, a combination of both gentamicin-loaded cement and cefuroxime prevented biofilm formation by these eight isolates. Our results indicate that this antibiotic combination may protect against infection after intra-operative challenge with bacteria present in low numbers as a result of contamination from the skin but would not protect against bacteria present in high numbers as a result of overt infection of an existing implant.
