Seen but never heard: rethinking approaches to researching racism and young children

This paper is concerned with the methodology underlying attempts to understand the nature and impact of racism among young children. In drawing upon data gathered from a year-long ethnographic study of five- and six-year-old children in an English multi-ethnic, inner-city primary school, the paper provides a critique of traditional approaches to the study of racial attitudes among young children. It is argued that such research has been conceived through the articulation of two, inter-related discourses on children and on 'race'; the former couched in traditional socialisation and developmental models of childhood with their tendency to neglect the agency and social competency of young children and the latter being embedded within essentialist notions of 'race' and ethnicity that tend to deny the contingent and context-specific nature of racialised identities. The paper argues that the result of this has been that while children have often been the objects of research they have rarely been the subjects; in other words they are often seen but never heard. The paper argues for the need to move beyond the methodological confines set by these discourses and rethink alternative approaches that begin with the assumption that young children are socially competent. One such approach, drawing upon ethnographic methods and fore-grounding the importance of largely unstructured small group interviews with young children, is illustrated. Through the use of a number of examples, it is shown how this approach can help to emphasise the ability of children as young as five and six to respond to and negotiate their social worlds and more specifically within this the competency with which they are able to appropriate, rework and reproduce a number of discourses on 'race' to make sense of their own social experiences. In doing this the paper also illustrates the way in which it provides a methodology able to draw out and highlight the contradictions, contingency and complexity of racialised identities among young children. Ultimately, it is an approach concerned with placing the children themselves central within the research processes and foregrounding their voices and experiences.

A test for psychometric function shift

A nonparametric, small-sample-size test for the homogeneity of two psychometric functions against the left- and right-shift alternatives has been developed. The test is designed to determine whether it is safe to amalgamate psychometric functions obtained in different experimental sessions. The sum of the lower and upper p-values of the exact (conditional) Fisher test for several 2 × 2 contingency tables (one for each point of the psychometric function) is employed as the test statistic. The probability distribution of the statistic under the null (homogeneity) hypothesis is evaluated to obtain corresponding p-values. Power functions of the test have been computed by randomly generating samples from Weibull psychometric functions. The test is free of any assumptions about the shape of the psychometric function; it requires only that all observations are statistically independent. © 2011 Psychonomic Society, Inc.

Parallel and nonparallel ecological, morphological and genetic divergence in lake-stream stickleback from a single catchment

Parallel phenotypic evolution in similar environments has been well studied in evolutionary biology; however, comparatively little is known about the influence of determinism and historical contingency on the nature, extent and generality of this divergence. Taking advantage of a novel system containing multiple lake-stream stickleback populations, we examined the extent of ecological, morphological and genetic divergence between three-spined stickleback present in parapatric environments. Consistent with other lake-stream studies, we found a shift towards a deeper body and shorter gill rakers in stream fish. Morphological shifts were concurrent with changes in diet, indicated by both stable isotope and stomach contents analysis. Performing a multivariate test for shared and unique components of evolutionary response to the distance gradient from the lake, we found a strong signature of parallel adaptation. Nonparallel divergence was also present, attributable mainly to differences between river locations. We additionally found evidence of genetic substructuring across five lake-stream transitions, indicating that some level of reproductive isolation occurs between populations in these habitats. Strong correlations between pairwise measures of morphological, ecological and genetic distance between lake and stream populations supports the hypothesis that divergent natural selection between habitats drives adaptive divergence and reproductive isolation. Lake-stream stickleback divergence in Lough Neagh provides evidence for the deterministic role of selection and supports the hypothesis that parallel selection in similar environments may initiate parallel speciation.

Nationalism, Territory, and Organized Violence: Introduction to the Special Issue

Recent decades have seen significant advances in research on the relationship between nationalist ideology and organized violence. New scholarship has paid much closer attention to the microdynamics of violence, the strikingly uneven distribution of violence, the relationship between master cleavages and intimate local and personal struggles, and to process, history, and contingency. Nationalist ideology is understood to be bound up intimately with institutions and with everyday relationships at the local level. We introduce the contributions to this special issue, outlining the way in which they highlight the power of ideas, narratives, and microlevel solidarity in mobilization for violence and how they address the crucial importance of territoriality in linking ideas and action.

The overlap between war and crime: unpacking Foucault and Agamben’s studies within the context of the war on terror

This article will consider the current convergence between war and crime by unpacking Foucault’s analysis of power and Agamben’s elaboration on the conjunction between the banning of a life and the constitution of the polity. It will show that these perspectives link together crime and war as mechanisms that contribute to the governance of the population by legitimating authority and their use of force through the military and the police while excluding part of the population. It will expose how these convergences highlight the problem of the political in the constitution of the social order at the global level. In the current contingency, crime and war are strongly implicated in the crucial political function of calling people to share their similarities and differences, and yet are not the best mechanisms for dealing with the sharing of a world in common.

Psychic Distance, its Business Impact and Modes of Coping: A Study of British and Indian Partner SMEs

This paper reports one of the first investigations to analyze inter-partner perceptions of psychic distance between two countries. Its empirical focus is British and Indian SMEs engaged in business with each other. It examines different dimensions of psychic distance, their impact and modes of coping with them. Potential firm-level and individual influences are also taken into account. The paper aims to transcend some of the conceptual and methodological limitations of previous research on the subject and to identify the theoretical and practical implications that arise. A ‘mirror’ approach is applied, accessing both partners’ perceptions. These are assessed through a ‘mixed’ method combining quantitative measurement with qualitative interpretations. Psychic distance dimensions are found to vary in their impact on doing business with the other country, and there is also variation according to the firm’s sector. There is considerable asymmetry in British and Indian partners’ perceptions of psychic distance but the degree of difference between their psychic distance evaluations lacks predictive power. Culturally embedded psychic distance dimensions tend to have less impact and to be easier to cope with than institutionally embedded dimensions. Four categories of coping are identified. The principal theoretical implication of this study is that a contingency perspective needs to be adopted in the field of ‘distance’ research, taking account of factors such as a firm’s sector, and that this will require a more complex analytical framework that hitherto.

Encouraging children to think counterfactually enhances blocking in a causal learning task

According to a higher order reasoning account, inferential reasoning processes underpin the widely observed cue competition effect of blocking in causal learning. The inference required for blocking has been described as modus tollens (if p then q, not q therefore not p). Young children are known to have difficulties with this type of inference, but research with adults suggests that this inference is easier if participants think counterfactually. In this study, 100 children (51 five-year-olds and 49 six- to seven-year-olds) were assigned to two types of pretraining groups. The counterfactual group observed demonstrations of cues paired with outcomes and answered questions about what the outcome would have been if the causal status of cues had been different, whereas the factual group answered factual questions about the same demonstrations. Children then completed a causal learning task. Counterfactual pretraining enhanced levels of blocking as well as modus tollens reasoning but only for the younger children. These findings provide new evidence for an important role for inferential reasoning in causal learning.

Distributed MPC for Frequency Regulation in Multi-Terminal HVDC Grids

High Voltage Direct Current (HVDC) lines allow large quantities of power to be
transferred between two points in an electrical power system. A Multi-Terminal HVDC (MTDC) grid consists of a meshed network of HVDC lines, and this allows energy reserves to be shared between a number of AC areas in an efficient manner. Secondary Frequency Control (SFC) algorithms return the frequencies in areas connected by AC or DC lines to their original setpoints after Primary Frequency Controllers have been called following a contingency. Where multiple
TSOs are responsible for different parts of a MTDC grid it may not be possible to implement SFC from a centralised location. Thus, in this paper a simple gain based distributed Model Predictive Control strategy is proposed for Secondary Frequency Control of MTDC grids which allows TSOs to cooperatively perform SFC without the need for centralised coordination.

Tooth replacement for partially dentate elders: a willingness-to-pay analysis

Objectives: The primary aim of this study was to investigate partially dentate elders’ willingness-to-pay (WTP) for two different tooth replacement strategies: using Removable Partial Dentures (RPDs) and, functionally orientated treatment (SDA). The secondary aim was to measure the same patient group’s WTP for dental implants. Methods: Patients who had completed a previous RCT comparing two tooth replacement strategies (RPDs and SDA) were recruited. 59 patients were asked to indicate their WTP for treatment to replace missing teeth in a number of hypothetical scenarios using the payment card method of contingency evaluation coupled to different costs. Data were collected on patients’ social class, longest held occupation, income levels and social circumstances. Results: The median age for the patient sample was 72.0 years (IQR: 71-75 years). Patients who had previously been provided with RPDs indicated that their WTP for this treatment strategy was significantly higher than those patients who had received SDA treatment (Mann-Whitney U Test: p<0.001). This group were also WTP a higher price for SDA treatment than those patients who had previously been treated according to this modality (Mann-Whitney U Test: p=0.005). The results indicated that patients’ age was not correlated with WTP but both social class and current income levels were significantly correlated (Spearman’s rank correlation: p<0.05). Patients in both treatment groups exhibited llittle WTP for dental implant treatment with a median price recorded which was lower than either RPD or SDA treatment. Conclusions: Amongst this patient cohort previous treatment experience had a strong influence on WTP as did social class and current income levels. The patients’ WTP indicated that they did not value dental implants over simpler forms of tooth replacement such as RPDs or a SDA approach.

An efficient and robust case sorting for algorithm for transient stability assessment

An efficient and robust case sorting algorithm based on Extended Equal Area Criterion (EEAC) is proposed in this paper for power system transient stability assessment (TSA). The time-varying degree of an equivalent image system can be deduced by comparing the analysis results of Static EEAC (SEEAC) and Dynamic EEAC (DEEAC), the former of which neglects all time-varying factors while the latter partially considers the time-varying factors. Case sorting rules according to their transient stability severity are set combining the time-varying degree and fault messages. Then a case sorting algorithm is designed with the “OR” logic among multiple rules, based on which each case can be identified into one of the following five categories, namely stable, suspected stable, marginal, suspected unstable and unstable. The performance of this algorithm is verified by studying 1652 contingency cases from 9 real Chinese provincial power systems under various operating conditions. It is shown that desirable classification accuracy can be achieved for all the contingency cases at the cost of very little extra computational burden and only 9.81% of the whole cases need to carry out further detailed calculation in rigorous on-line TSA conditions.

Moment of stasis: the successful failure of a constitution for Europe

The 2005 French and Dutch negative votes on the Constitution open up a space of conceptualisation, not only of Europe's relation to its demos, but significantly to its failures. Through a critical analysis of mainly Niklas Luhmann's systems theory, the article proposes taking a distance from traditional constitutional dogmatics that are no longer capable of dealing with the paradox of contemporary society, and more specifically with the eventual resurgence of the European project as one of absence and stasis: the two terms are used to explain the need, on the one hand, to maintain the 'absent community' of Europe, and, on the other, to start realising that any conceptualisation of the European project will now have to take place in that space of instability and contingency revealed by the constitutional failure. The relation between law and politics, the location of a constitution, the distinction between social and normative legitimacy, the connection between European identity and demos, and the concept of continuity between constitutional text and context are revisited in an attempt to trace the constitutional failure as the constitutional moment par excellence.
