Resurgence of inner solutions for perturbations of the McMillan map

A sequence of “inner equations” attached to certain perturbations of the McMillan map was considered in [MSS09], their solutions were used in that article to measure an exponentially small separatrix splitting. We prove here all the results relative to these equations which are necessary to complete the proof of the main result of [MSS09]. The present work relies on ideas from resurgence theory: we describe the formal solutions, study the analyticity of their Borel transforms and use ´Ecalle’s alien derivations to measure the discrepancy between different Borel-Laplace sums.

Movilidad ocupacional de los inmigrantes en una economía de bajas cualificaciones. El caso de España

Esta investigación analiza la movilidad ocupacional de los inmigrantes entre sus países de origen y España, así como sus principales determinantes. La misma se basa en los microdatos de la Encuesta Nacional de Inmigrantes y el uso de una escala de estatus ocupacional de carácter internacional (ISEI). La evidencia muestra que, por lo general, los inmigrantes sufren una fuerte degradación ocupacional en España con respecto a sus países de origen. Ésta se explica en buena medida por la intensa degradación que suelen experimentar al incorporarse al mercado de trabajo español, puesto que la mejora ocupacional asociada a su estancia en nuestro país es limitada. La degradación ocupacional al llegar es mayor para las mujeres, los inmigrantes de mayor nivel educativo y los procedentes de países en desarrollo. La recuperación posterior confirma la hipótesis de una movilidad ocupacional en forma de U profunda para los dos últimos colectivos, mientras que las mujeres padecen mayores dificultades para progresar ocupacionalmente. Residir en España, convalidar estudios extranjeros, aprender castellano y regularizar la situación documental mejoran el estatus ocupacional, pero, excepto en el último caso, de forma lenta. Acceder al primer empleo en España a través de redes informales tiene un efecto negativo sobre el logro ocupacional. Por último, mayor tiempo buscando empleo y una búsqueda de trabajo que incluya la movilidad geográfica se traducen en una mejora ocupacional mayor, mientras que el desempleo tiene un efecto negativo.

Tasas de reincidencia 2008 de justícia juvenil: actualización de la tasa de reincidencia de los jóvenes sometidos a medidas de libertad vigilada e internamiento en centro

El estudio actualiza por cuarto año las tasas de reincidencia juvenil en las medidas de libertad vigilada e internamiento en Catalunya. En este caso se ha seguido a la población que finalizó una medida el año 2005 y se les ha seguido hasta el 31 de diciembre de 2008. Los resultados nos dicen que se mantiene la tasa de libertad vigilada (23,0%) y sube ligeramente aunque sin ser significativamente diferente respecto del año pasado la de internamiento (62,3%). The study updates the rates for the fourth year of recidivism in the juvenile probation and confinement in Catalunya. In this case, the population that ends a punishment in 2005 were followed until December 31, 2008. The results tell us that maintaining the rate of probation (23.0%) and rises slightly but not significantly different from last year the rate of confinement (62.3%).

Col·laboració a l'estudi de les plantes invasores del Parc Natural de l'Alt Pirineu: cartografia de detall i recull de mesures de gestió

La intrusió de les plantes exòtiques invasores en els espais naturals protegits de Catalunya s’ha convertit en un problema de primer ordre. En alguns d’aquests espais fa temps que s’han començat a gestionar aquestes espècies exòtiques. No és el cas del PNAP, que degut a la seva recent creació, encara no ha pogut tractar a fons aquesta problemàtica. Per tant, amb el present estudi s’ha treballat en conèixer la distribució d’aquetes espècies en el Parc i en crear una base de referència. La major part de les plantes trobades estan situades en llocs on la pressió humana es molt forta. Un cop establertes prop de les àrees més antropitzades, aquestes espècies es disseminen pel territori aprofitant-se de les zones degradades per establir-se. Per aquesta raó, també es proposen les mesures d’actuació més adients per a gestionar aquestes espècies en el territori de l’Alt Pirineu, prenent com a referent les actuacions que es duen a terme avui arreu del món.

Gender, family and employment in comparative perspective: the realities and representations of rqual rpportunities in Britain and France

In this paper, we will explore how contrasting national discourses relating to women, and gender equality have been incorporated into and reflected in national policies. In the first section, we will outline the recent history of EU equal opportunities policy, in which positive action has been replaced by a policy of 'mainstreaming'. Second, we will describe the evolution of policies towards women and equal opportunities in Britain and France. It will be argued that whereas some degree of positive action for women has been accepted in Britain, this policy is somewhat alien to French thinking about equality - although pro-natalist French policies have resulted in favourable conditions for employed mothers in France. In the third section, we will present some attitudinal evidence, drawn from national surveys, which would appear to reflect the national policy differences we have identified in respect of the 'equality agenda'. In the fourth section, we will draw upon biographical interviews carried out with men and women in British and French banks in order to illustrate the impact of these cross-national differences within organizations and on individual lives. We demonstrate that positive action gender equality policies have made an important impact in British banks, while overt gender exclusionary practices still persist in the French banks studied. In the conclusion, we reflect on the European policy implications of our findings.

Invading freshwater snails and biological control in Martinique Island, French West Indies

Eight alien freshwater snail species were introduced into Martinique Island during the last 50 years. The introduced snails include four planorbids (Biomphalaria straminea, Helisoma duryi, Amerianna carinata and Gyraulus sp.), three thiarids (Melanoides tuberculata, M. amabilis and Tarebia granifera) and one ampullarid (Marisa cornuarietis). Four of these species rapidly colonized the whole Martinican hydrographic system whereas the other four remained restricted to some particular sites. The invasion processes were documented during the last 20 years and showed (i) a rapid invasion of the island by several morphs of M. tuberculata at the beginning of the 80's; (ii) the introduction of T. granifera in 1991 and M. amabilis in 1997; and (iii) the rapid spread of these last two species throughout the island. In the years following its introduction, M. tuberculata was used in biological control experiments against the snail hosts of schistosomiasis, B. glabrata and B. straminea. Experiments were conducted with success in several groups of water-cress beds which constituted the latest transmission sites for schistosomiasis at the beginning of the 80's. A malacological survey carried out in 2000 all over the island showed the absence of B. glabrata but the presence of some residual populations of B. straminea. Long-term studies carried out in Martinique have shown that the thiarids are able to maintain relatively stable populations over a long period of time, thus preventing recolonization by the snail hosts. Within this context the invasion of the hydrographic system of Martinique by thiarid snails has resulted in an efficient and sustainable control of the intermediate hosts of schistosomiasis.

Espais femenins en l'obra de Paul Gauguin

La societat actual figura arrelada a un discurs sobre el femení, que desenvolupat durant el segle XVIII s'ha anat obrint camí insistentment a través de les imatges. A través de l'obra del pintor Paul Gauguin aquest treball presten mostrar que el confinament de la dona a l'espai domèstic i la pretesa relació d'aquesta amb altres elements és fruit de la mateixa ideologia que confina a la dona a l'espai privat i a l'home a l'espai públic.

A Review of Harm Reduction Approaches in Ireland and Evidence from the International Literature

This report examines international literature on harm reduction and also presents primary research in health services in Ireland on approaches to harm reduction. The aim of harm reduction efforts is to minimise the risks stemming from shared use of drug-use paraphernalia, such as needle exchange programmes. One of the criticisms of Irish drug services is that the restricted opening hours and limited number of exchange services may contribute to continued sharing of needles among drug users. The report points out that other non-injecting paraphernalia such as spoons are also associated with the risk of contracting diseases, yet services do not as yet focus on them. The report notes that specific risk factors that contribute to risky drug practices include youth, a shorter injecting history, confinement to prison, homelessness and being involved in a sexual relationship with another intravenous drug user. The report suggests that harm reduction practices can be introduced into a prison population without a subsequent increase in drug consumption rates. The provision of consumption rooms and the prescription of heroin are also discussed, with the report noting that legislation would have to altered to implement these new strategies.This resource was contributed by The National Documentation Centre on Drug Use.

Long time behaviour of diffusing particles in constrained geometries; application to chromatin motion

Inspired by experiments that use single-particle tracking to measure the regions of confinement of selected chromosomal regions within cell nuclei, we have developed an analytical approach that takes into account various possible positions and shapes of the confinement regions. We show, in particular, that confinement of a particle into a subregion that is entirely enclosed within a spherical volume can lead to a higher limit of the mean radial square displacement value than the one associated with a particle that can explore the entire spherical volume. Finally, we apply the theory to analyse the motion of extrachromosomal chromatin rings within nuclei of living yeast.

Hierarchic species-area relationships and the management of forest habitat islands in intensive farmland

Habitat loss and fragmentation due to land use changes are major threats to biodiversity in forest ecosystems, and they are expected to have important impacts on many taxa and at various spatial scales. Species richness and area relationships (SARs) have been used to assess species diversity patterns and drivers, and thereby in the establishment of conservation and management strategies. Here we propose a hierarchical approach to achieve deeper insights on SARs in small forest islets in intensive farmland and to address the impacts of decreasing naturalness on such relationships. In the intensive dairy landscapes of Northwest Portugal, where small forest stands (dominated by pines, eucalypts or both) represent semi-natural habitat islands, 50 small forest stands were selected and surveyed for vascular plant diversity. A hierarchical analytical framework was devised to determine species richness and inter- and intra-patch SARs for the whole set of forest patches (general patterns) and for each type of forest (specific patterns). Differences in SARs for distinct groups were also tested by considering subsets of species (native, alien, woody, and herbaceous). Overall, values for species richness were confirmed to be different between forest patches exhibiting different levels of naturalness. Whereas higher values of plant diversity were found in pine stands, higher values for alien species were observed in eucalypt stands. Total area of forest (inter-patch SAR) was found not to have a significant impact on species richness for any of the targeted groups of species. However, significant intra-patch SARs were obtained for all groups of species and forest types. A hierarchical approach was successfully applied to scrutinise SARs along a gradient of forest naturalness in intensively managed landscapes. Dominant canopy tree and management intensity were found to reflect differently on distinct species groups as well as to compensate for increasing stand area, buffering SARs among patches, but not within patches. Thus, the maintenance of small semi-natural patches dominated by pines, under extensive practices of forest management, will promote native plant diversity while at the same time contributing to limit the expansion of problematic alien invasive species.

GroEL and CCT are catalytic unfoldases mediating out-of-cage polypeptide refolding without ATP.

Chaperonins are cage-like complexes in which nonnative polypeptides prone to aggregation are thought to reach their native state optimally. However, they also may use ATP to unfold stably bound misfolded polypeptides and mediate the out-of-cage native refolding of large proteins. Here, we show that even without ATP and GroES, both GroEL and the eukaryotic chaperonin containing t-complex polypeptide 1 (CCT/TRiC) can unfold stable misfolded polypeptide conformers and readily release them from the access ways to the cage. Reconciling earlier disparate experimental observations to ours, we present a comprehensive model whereby following unfolding on the upper cavity, in-cage confinement is not needed for the released intermediates to slowly reach their native state in solution. As over-sticky intermediates occasionally stall the catalytic unfoldase sites, GroES mobile loops and ATP are necessary to dissociate the inhibitory species and regenerate the unfolding activity. Thus, chaperonin rings are not obligate confining antiaggregation cages. They are polypeptide unfoldases that can iteratively convert stable off-pathway conformers into functional proteins.

Multiple origins of invasive and "native" water frogs (Pelophylax spp.) in Switzerland

The marsh frog (Pelophylax ridibundus) has been introduced in many places of Central and Western Europe due to commercial trades with Eastern Europe, and is rapidly replacing the native pool frog (P. lessonae). A large number of Pelophylax species are distributed in Eastern Europe and the strong phenotypic similarity between these species is rendering their identification hazardous. Consequently, alien populations of Pelophylax might not strictly be composed of P. ridibundus as previously suspected. In the present study, we analyzed the cytochrome b and NADH dehydrogenase subunit 3 genes of introduced and native Pelophylax from Switzerland (299 individuals), in order to properly identify the source populations of the invaders and the genetic status of the native species. Our study highlighted the occurrence of several genetic lineages of invasive frogs in western Switzerland. Unexpectedly, we also showed that several populations of the native pool frog (P. lessonae) cluster with the Italian pool frog P. bergeri from central Italy (considered by some authors as a subspecies of P. lessonae) Hence, these populations are probably also the result of introductions, meaning that the number of native P. lessonae populations is less important than expected in Switzerland. These findings have important implications concerning the conservation of the endemic pool frog populations, as the presence of multiple alien species could strongly affect their long-term subsistence.

Calorimetry of dehydrogenation and dangling-bond recombination in several hydrogenated amorphous silicon materials

Differential scanning calorimetry (DSC) was used to study the dehydrogenation processes that take place in three hydrogenated amorphous silicon materials: nanoparticles, polymorphous silicon, and conventional device-quality amorphous silicon. Comparison of DSC thermograms with evolved gas analysis (EGA) has led to the identification of four dehydrogenation processes arising from polymeric chains (A), SiH groups at the surfaces of internal voids (A'), SiH groups at interfaces (B), and in the bulk (C). All of them are slightly exothermic with enthalpies below 50 meV/H atoms , indicating that, after dissociation of any SiH group, most dangling bonds recombine. The kinetics of the three low-temperature processes [with DSC peak temperatures at around 320 (A),360 (A'), and 430°C (B)] exhibit a kinetic-compensation effect characterized by a linea relationship between the activation entropy and enthalpy, which constitutes their signature. Their Si-H bond-dissociation energies have been determined to be E (Si-H)0=3.14 (A), 3.19 (A'), and 3.28 eV (B). In these cases it was possible to extract the formation energy E(DB) of the dangling bonds that recombine after Si-H bond breaking [0.97 (A), 1.05 (A'), and 1.12 (B)]. It is concluded that E(DB) increases with the degree of confinement and that E(DB)>1.10 eV for the isolated dangling bond in the bulk. After Si-H dissociation and for the low-temperature processes, hydrogen is transported in molecular form and a low relaxation of the silicon network is promoted. This is in contrast to the high-temperature process for which the diffusion of H in atomic form induces a substantial lattice relaxation that, for the conventional amorphous sample, releases energy of around 600 meV per H atom. It is argued that the density of sites in the Si network for H trapping diminishes during atomic diffusion

Selected Information About County Jails and Adult Detention Facilities in Iowa, 2003

During the 2002 session of the Iowa General Assembly, Senate File 2278 was enacted, establishing a new Section 356.36A within the Iowa Code. Subsequently, House File 2623 was enacted, which served to make a minor amendment to Senate File 2278. The Governor subsequently signed the amended legislation into law. The final version of the new Section 356.36A required that the Iowa Department of Human Rights, Division of Criminal and Juvenile Justice Planning and Statistical Analysis Center (CJJP) prepare a report for the Legislature “analyzing the confinement and detention needs of jails and facilities established pursuant to chapters 356 and 356A.

Symptômes dépressifs et douleurs diffuses chez un détenu : penser au déficit en vitamine D [Depressive symptoms and widespread pains in a prisoner. Think on vitamin D deficiency].

The confinement can lead to an important limitation of sun exposure of the prisoners. This limitation can lead to a deficit in vitamin D, source of diverse disorders. Diffuse pains of members and of joints are the most classics troubles. The association of vitamin D deficiency and psychiatric disorders is frequent but badly known. Even if there is still no evidence indicating a cause and effect relationship between vitamin D deficiency and depressive episodes, the contribution of vitamin D deficiency in the arisen of a depression has to be considered. The treatment of vitamin D deficiency cannot, in itself, constitute a treatment of the depressive disorder but contributes to the improvement of the whole status The psychiatric follow-up remains indispensable, in particular because of the suicidal risk, particularly present in prison.
