Field theory actions for ambitwistor string and superstring

We analyze the free ambitwistor string field theory action for the bosonic string, heterotic string and both GSO sectors of the Type II string. The spectrum contains non-unitary states and provides an interesting consistency test for one-loop ambitwistor string computations.Comment: 14 pages, Fixed typo

On the Spectrum and Spacetime Supersymmetry of Heterotic Ambitwistor String

We analyse the BRST cohomology of the Ramond sector of heterotic ambitwistor theory. We also write the free string field theory action and compute the supersymmetry transformations.Comment: 13 pages ( Submission to JHEP and minor typos fixed

Déclassement des jeunes et politiques de l'emploi. Exploration de l'enquête "Génération 98" du Céreq

Cette étude s'intéresse aux décalages entre l'emploi et la formation des jeunes présents dans l'enquête "Génération 98" du Céreq et compare les situations des jeunes qui bénéficient d'un emploi aidé ou "normal". Afin de percevoir plusieurs visages du déclassement, une approche statistique, fixant des normes, est confrontée à une approche subjective, telle qu'elle est ressentie par les salariés. L'étude des décalages entre la catégorie socioprofessionnelle de l'emploi et le niveau de diplôme des jeunes montre que, jusqu'au niveau bac+2, les emplois aidés préservent du déclassement. Pour autant, les bénéficiaires des mesures pour l'emploi se sentent plus souvent que les autres employés en dessous de leur niveau de compétence. L'hypothèse est que le déclassement peut s'analyser comme un problème de file d'attente et que les emplois aidés agissent sur les phénomènes de concurrence pour l'emploi.Marché du travail, politique de l'emploi, relation formation-emploi, jeune, déclassement.

Rehabilitation and (dis-)empowerment a discourse analysis of interviews with subjects variously positioned within the South African Correctional Services system

The present treatise is an attempt to come to terms with the, by all accounts, dismal conditions that exist in present-day South African prisons by addressing these conditions as they are reflected in two interviews with individuals intimately acquainted with them, as well as by pertinent media-reports. The study is predicated on the belief that the most suitable methodological approach to a situation characterized by extreme conflicts and tensions in terms of power relations, is provided by (mainly Foucaultian) discourse-theory and the discourse-analysis that it makes possible. Consequently, after an introduction in which the present study is justified, followed by a theoretical section outlining the terrain of discourse theory and discourse-analysis, two chapters are devoted to specific discourse-analyses of interviews with an awaiting-trial prisoner in a South African prison and a warden employed at the same institution, with a view to uncovering the power-relations at stake here. While acknowledging that the implications of the insights thus afforded are not, strictly speaking, generalizable in a positivist manner, and that the power-relations brought to light by means of these discourse-analyses are highly specific, it is argued that various other studies pertaining to the South African prison system indicate that these powerrelations – more specifically the disempowerment of prisoners by the functioning of violently hierarchical discursive practices in South African prisons - are not restricted to the prison in question. In fact, given the SA Correctional Services’ stated policy of rehabilitation, it is striking that there is scant evidence of any such rehabilitation in the prisons concerned – at least in the sense of prisoners attaining a level of moral responsibility that would enable them to live as accountable citizens in a democratic society. In conclusion it is argued that the present state of affairs, far from being conducive to the stated goal of rehabilitation, actually undermines its realization, and that the social and economic inequalities in South Africa, exacerbated by the union between ‘democracy’ and global capitalism, are perpetuated and reinforced by the existing discursive practices in South African prisons

Testing the structure and process of personality using ambulatory assessment data : an overview of within-person and person-specific techniques

In the present article, we discuss the potential of ambulatory assessment for an idiographic study of the structure and process of personality. To this end, we first review important methodological issues related to the design and implementation of an ambulatory assessment study in the personality domain, including methods of ambulatory assessment, frequency of measurement and duration of the study, ambulatory assessment scales and questionnaires, participant selection, training and motivation, and ambulatory assessment hard- and software. Next, we provide a detailed outline of available analytical approaches that can be used to analyze the intensive longitudinal data generated by an ambulatory assessment study. By doing this, we hope to familiarize personality scholars with these methods and to provide guidance for their use in the field of personality psychology and beyond

Converts and conservatives: missionary representations of African rulers in the Northern Transvaal, c. 1870-1900

During the second half of the nineteenth century, the Berlin Mission Society made strenuous efforts to convert the rulers of the people in whose areas they worked in the Northern Transvaal. In this they were largely unsuccessful. This raises questions about what forces influenced success and failure, and how the missionaries interpreted this. In this article, we interrogate the Berlin Missions Society’s accounts of the life and death of August Makhahane, a ruler of the Vhavenda who converted to Christianity, against the background of the accounts dealing with Matsiokwane Leboho, a ruler of the Bahananwa who did not convert. Through such a comparison, we aim at exploring the contrasted ways in which the Berlin missionaries reported about the two rulers

The effect of being imitated on empathy for pain in adults with high-functioning autism : disturbed self-other distinction leads to altered empathic responding

Autism spectrum disorder is a neurodevelopmental disorder that is associated with problems in empathy. Recent research suggests that impaired control over self-other overlap based on motor representations in individuals with autism spectrum disorder might underlie these difficulties. In order to investigate the relationship of self-other distinction and empathy for pain in high-functioning autism and matched controls, we manipulated self-other distinction by using a paradigm in which participants are either imitated or not by a hand on a computer screen. A strong pain stimulus is then inflicted on the observed hand. Behavioral and physiological results in this study showed that overall affective responses while watching pain movies were the same in adults with high-functioning autism as in controls. Furthermore, controls showed higher affective responding after being imitated during the whole experiment, replicating previous studies. Adults with high-functioning autism, however, showed increased empathic responses over time after being imitated. Further exploratory analyses suggested that while affective responding was initially lower after being imitated compared to not being imitated, affective responding in the latter part of the experiment was higher after being imitated. These results shed new light on empathic abilities in high-functioning autism and on the role of control over self-other representational sharing
