An Analysis of the Electoral Use of Policy on Law and Order by New Labour

There has been much debate regarding the electoral strategy adopted by New Labour in the lead-up to and then during their time in government. This paper addresses the issue from the perspective of left/right and libertarian/authoritarian considerations by examining data on individual attitudes from the British Social Attitudes survey between 1986 and 2009. The analysis indicates that New Labour’s move towards the right on economic and public policy was the main driver towards attracting new centrist voters and could thus be labelled ‘broadly’ populist. The move towards a tougher stance on law and order was more ‘narrowly’ populist in that it was used more to minimise the reduction in support from Labour’s traditional base on the left than to attract new votes.

Empirical testing of genuine savings as an indicator of weak sustainability: a three-country analysis of long run trends

Genuine Savings has emerged as a widely-used indicator of sustainable development. In this paper, we use long-term data stretching back to 1870 to undertake empirical tests of the relationship between Genuine Savings (GS) and future well-being for three countries: Britain, the USA and Germany. Our tests are based on an underlying theoretical relationship between GS and changes in the present value of future consumption. Based on both single country and panel results, we find evidence supporting the existence of a cointegrating (long run equilibrium) relationship between GS and future well-being, and fail to reject the basic theoretical result on the relationship between these two macroeconomic variables. This provides some support for the GS measure of weak sustainability. We also show the effects of modelling shocks, such as World War Two and the Great Depression.

Intraobserver and interobserver variability of ascending aorta diameter measurements as assessed by ECG-gated MDCT : automatic versus manual measurements : P15

Purpose: Revolutionary endovascular treatments are on the verge of being available for management of ascending aortic diseases. Morphometric measurements of the ascending aorta have already been done with ECG-gated MDCT to help such therapeutic development. However the reliability of these measurements remains unknown. The objective of this work was to compare the intraobserver and interobserver variability of CAD (computer aided diagnosis) versus manual measurements in the ascending aorta. Methods and materials: Twenty-six consecutive patients referred for ECG-gated CT thoracic angiography (64-row CT scanner) were evaluated. Measurements of the maximum and minimum ascending aorta diameters at mid-distance between the brachiocephalic artery and the aortic valve were obtained automatically with a commercially available CAD and manually by two observers separately. Both observers repeated the measurements during a different session at least one month after the first measurements. Intraclass coefficients as well the Bland and Altman method were used for comparison between measurements. Two-paired t-test was used to determine the significance of intraobserver and interobserver differences (alpha = 0.05). Results: There is a significant difference between CAD and manual measurements in the maximum diameter (p = 0.004) for the first observer, whereas the difference was significant for minimum diameter between the second observer and the CAD (p <0.001). Interobserver variability showed a weak agreement when measurements were done manually. Intraobserver variability was lower with the CAD compared to the manual measurements (limits of variability: from -0.7 to 0.9 mm for the former and from -1.2 to 1.3 mm for the latter). Conclusion: In order to improve reproductibility of measurements whenever needed, pre- and post-therapeutic management of the ascending aorta may benefit from follow-up done by a unique observer with the help of CAD.

A public key encryption based on third order linear sequences

Based on third order linear sequences, an improvement version of the Diffie-Hellman distribution key scheme and the ElGamal public key cryptosystem scheme are proposed, together with an implementation and computational cost. The security relies on the difficulty of factoring an RSA integer and on the difficulty of computing the discrete logarithm.

The costs of parasitism and anti-parasitic defense in the common vole

Résumé : Les relations entre un parasite et son hôte sont avant tout marquées par le coût pour l'hôte que représente la ponction de ressources au profit du parasite et ses conséquences sur les traits d'histoires de vie de l'hôte. Pour contenir la réduction de leur valeur reproductive, les hôtes ont acquis au cours de l'évolution des mécanismes soit de lutte contre les parasites, soit de réallocations des ressources. Curieusement les effets des ectoparasites sur la biologie de mammifères ont été peu étudiés. Dans une première expérience à long terme, nous avons examiné sous un angle intégratif si les puces Nosopsyllus fasciatus affectent certains paramètres physiologiques des campagnols des champs Microtus arvalis. Nous avons également testé si les puces peuvent réduire la longévité et si oui, si ce pourrait être dû à une accélération de la sénescence. Ensuite nous avons testé si la simple activation répétée du système immunitaire comme lors d'une infestation chronique pouvait aussi réduire la longévité. Dans une dernière expérience, nous avons d'abord testé si l'infestation par des puces de jeunes campagnols au stade néonatal (21 jours) pouvait modifier leur développement et leur phénotype adulte. Puis nous avons testé si la modification du phénotype adulte est une réponse prédite et potentiellement adaptative pour minimiser les effets des puces à l'âge adulte. Nos résultats montrent que l'infestation par des puces réduit la croissance subadulte, induit une forte anémie et une immunodépression, et augmente le métabolisme de repos. De plus les puces réduisent la longévité et la taille des testicules, réduisant fortement le succès reproducteur potentiel des individus parasités. La taille finale, c'est-à-dire le développement pré-adulte, détermine en grande part la longévité. La réduction de longévité ne devrait pas être due à l'investissement au profit du système immunitaire car l'activation chronique seule du système immunitaire ne réduit pas la longévité. L'infestation néonatale retarde légèrement le développement mais surtout modifie l'hématocrite et réduit les performances locomotrices des campagnols plus de 3 mois après l'infestation. Les effets immédiats du parasitisme sur la physiologie semblent bien supérieurs comparés aux effets à long terme. Nous n'avons pas d'éléments permettant d'affirmer que le parasitisme néonatal prépare les campagnols à faire face aux puces à l'âge adulte. Au contraire, le parasitisme néonatal interagit sur le parasitisme adulte pour augmenter le métabolisme de repos. Cette thèse offre une vision intégrative des mécanismes par lesquels les puces peuvent affecter la valeur reproductive de leurs hôtes. De façon générale, ces résultats 35 montrent l'importance des puces comme force de sélection chez les campagnols. Il est indispensable de prendre en compte les ectoparasites dans l'étude de l'écologie et des dynamiques de populations chez les mammifères. Summary : The relationship between a parasite and its host is fundamentally marked by the costs for host of the withdrawals of resources by parasite and the subsequent reduction in host life-history traits. Hosts have evolved a number of strategies to reduce these costs, either by fighting against the parasite directly or by reallocating resources to reduce costs on lifetime reproductive value. The effects of ectoparasites on burrowing mammals have been scarcely studied. In a first long-term experiment, we examined how fleas Nosopsyllus fasciatus affect physiological levels of the common vole, Microtus arvalis. We also examined whether fleas reduce longevity and if so, if it is due to an early senescence pattern. Then we tested if experimental activation of the immune system by repeated injections of an antigen could result in a shorter longevity. In the last experiment, we tested if short-lasting neonatal parasitism can have long-term effects on phenotype, and if these effects could induce a predictive response to reduce damages when parasitized at the adult stage. We found that parasitism by flea reduced subadult growth, induced anaemia and immunodepression, and increased energy consumption even when resting. Moreover fleas reduce longevity and testes size associated to splenomegaly, suggesting an overall reduction in fitness but we did not find any pattern of accelerated senescence explaining the early death of parasitized voles compared to non-parasitzed. The cost of mounting an immune response throughout life does not impair longevity, suggesting that it is the cost of parasitism that limits the longevity and not the immune investment. Neonatal infestation by fleas has long-term effects on physiology and reduces motor activity more than 3 months after infestation. The modification of physiology due to long-term effects seems weak compared to the immediate effects of adult infestation. We found no evidence that neonatal parasitism prepares voles to mount a predictive adaptive response in order to reduce effects of fleas on fitness components. On the contrary, neonatal parasitism seems to worsen the effect of adult parasitism. This thesis offers an integrative view of mechanisms by which fleas affect their host at the individual level. Overall, our results demonstrate the importance of fleas as a selective force in voles. These results highlight the importance of ectoparasitism in ecology of micromarnrnals and suggest a role in the dynamic of host populations.

Rigorous derivation of a nonlinear diffusion equation as fast-reaction limit of a continuous coagulation-fragmentation model with diffusion

Weak solutions of the spatially inhomogeneous (diffusive) Aizenmann-Bak model of coagulation-breakup within a bounded domain with homogeneous Neumann boundary conditions are shown to converge, in the fast reaction limit, towards local equilibria determined by their mass. Moreover, this mass is the solution of a nonlinear diffusion equation whose nonlinearity depends on the (size-dependent) diffusion coefficient. Initial data are assumed to have integrable zero order moment and square integrable first order moment in size, and finite entropy. In contrast to our previous result [CDF2], we are able to show the convergence without assuming uniform bounds from above and below on the number density of clusters.

A cross-cultural study of the higher-order structures underlying personality disorders in French-speaking Africa and Switzerland

Most studies about the higher-order dimensions to be considered in order to parsimoniously describe Personality Disorders (PDs) have identified between two and four factors but there is still no consensus about their exact number. In this context, the cultural stability of these structures might be a criterion to be considered. The aim of this study was to identify stable higher-order structures of PD traits in a French-speaking African and Swiss sample (N = 2,711). All subject completed the IPDE screening questionnaire. Using Everett's criterion and conducting a series of principal component analyses, a cross-culturally stable two- and four-factor structure were identified, associated with a total congruence coefficient of respectively .98 and .94 after Procrustes rotation. Moreover, these two structures were also highly replicable across the four African regions considered, North Africa, West Africa, Central Africa, and Mauritius, with a mean total congruence coefficient of respectively .97 and .87. The four-factor structure presented the advantage of being similar to Livesely's four components and of describing the ten PDs more accurately.
