Barriers and facilitators to effective coverage of Intimate Partner Violence services for immigrant women in Spain

Objective: To explore service providers’ perceptions in order to identify barriers and facilitators to effective coverage of Intimate Partner Violence (IPV) services for immigrant women in Spain, according to the different categories proposed in Tanahashi's model of effective coverage. Methods: A qualitative study based on 29 in-depth personal interviews and four group interviews with a total of 43 professionals working in public services (social and health-care services, women's refuges, the police force, the judiciary) and NGOs in Barcelona, Madrid, Valencia and Alicante (Spain) in 2011. Findings: Current IPV services in Spain partially fail in their coverage of abused immigrant women due to barriers of (i) availability, such as the inexistence of culturally appropriate services; (ii) accessibility, as having a residence permit is a prerequisite for women's access to different services and rights; (iii) acceptability, such as women's lack of confidence in the effectiveness of services; and (iv) effectiveness, for example, lack of specific training among professionals on the issues of IPV and immigration. However, interviewees also identified facilitators, such as the enabling environment promoted by the Spanish Law on Gender-Based Violence (1/2004), and the impetus it has provided for the development of other specific legislative tools to address IPV in immigrant populations in Spain (availability, accessibility and effectiveness). Conclusion: Whilst not dismissing cultural barriers, aspects related to service structure are identified by providers as the main barriers and facilitators to immigrant women use of IPV services. Despite noteworthy achievements, improvements are still required in terms of mainstreaming assistance tailored to immigrant women's needs in IPV policies and services.

Lymphatic vessel function in atherosclerosis

L'athérosclérose est une maladie inflammatoire chronique caractérisée par l'accumulation de cholestérol dans la paroi artérielle et associée à une réponse immunitaire anormale dans laquelle les macrophages jouent un rôle important. Récemment, il a été démontré que les vaisseaux lymphatiques jouent un rôle primordial dans le transport inverse du cholestérol (Martel et al. JCI 2013). L’objectif global de mon stage de maîtrise a été de mieux caractériser la dysfonction lymphatique associée à l’athérosclérose, en étudiant de plus près l’origine physiologique et temporelle de ce mauvais fonctionnement. Notre approche a été d’étudier, depuis l’initiation de l’athérosclérose jusqu’à la progression d’une lésion athérosclérotique tardive, la physiologie des deux constituants principaux qui forment les vaisseaux lymphatiques : les capillaires et collecteurs lymphatiques. En utilisant comme modèle principal des souris Ldlr-/-; hApoB100+/+, nous avons pu démontrer que la dysfonction lymphatique est présente avant même l’apparition de l’athérosclérose, et que cette dysfonction est principalement associée avec un défaut au niveau des vaisseaux collecteurs, limitant ainsi le transport de la lymphe des tissus périphériques vers le sang. De plus, nous avons démontré pour la première fois l’expression du récepteur au LDL par les cellules endothéliales lymphatiques. Nos travaux subséquents démontrent que ce défaut de propulsion de la lymphe pourrait être attribuable à l’absence du récepteur au LDL, et que la dysfonction lymphatique observée précocement dans l’athérosclérose peut être limitée par des injections systémiques de VEGF (vascular endothelial growth factor) –C. Ces résultats suggèrent que la caractérisation fonctionnelle de la capacité de pompage des vaisseaux collecteurs serait une condition préalable à la compréhension de l'interaction entre la fonction du système lymphatique et la progression de l'athérosclérose. Ultimement, nos travaux nous ont amené à considérer de nouvelles cibles thérapeutiques potentielles dans la prévention et le traitement de l’athérosclérose.

Towards a Fragmented Neighbourhood: Policies of the EU and Russia and their consequences for the area that lies in between. CEPS Essay No. 17, 17 October 2014

In the current volatile climate, the EU needs a strategy towards Russia that goes beyond sanctions. In reviewing the European Neighbourhood Policy and the Eastern Partnership, the EU’s incoming leadership should be more sensitive towards the existing political, diplomatic, economic, energy and military ties between Russia and the countries in the common neighbourhood. After all, it is by exploiting these ties that Russia was able to turn this neighbourhood into an area of destructive competition − the primary victim of which is Ukraine. Understanding Russia’s perceptions and being sensitive to these longstanding ties does not mean justifying their use by the Kremlin. Nevertheless, factoring these ties into the EU’s policies vis-à-vis its Eastern neighbourhood is a prerequisite for more reflective, responsive and effective EU policies.

Necessary desirability: The inherent contradiction in the European system. EuropEos Commentary No. 11, 9 June 2011

In all political systems there is a gap between the rhetoric of electoral programmes and the practical work of institutions, argues author Riccardo Perissich, but the ‘vision thing’ is often a necessary prerequisite to reaching difficult decisions. When it comes to European institutions, which include the member states acting collectively, the desirable vision – the goal of European unity – has always been there and is still very much alive. Also, the existence of a broadly defined political goal has often facilitated agreements that were in fact purely necessary. However, because we lack a pan-European constituency to debate it, the narrative about this goal has been translated into different languages and is all but common. In fact, we have never seriously tried to unify it. Indeed, Europeans stopped debating what is desirable a long time ago: they simply react to events.

EU Mission in Kosovo (EULEX): Constructing Ambiguity or Constructive Disunity? Transatlantic Security Paper No. 3, June 2011

In which skies should auspices about the future of EU foreign policy be looked for, Libya’s or Kosovo’s? Many commentators have been prompt in digging the grave for EU Security and Defense Policy after Member States’ discordance over taking military action against the Qaddafi regime1. However, as this paper will emphasize through the case of Kosovo, unanimity is not always an indispensable prerequisite – and should not be regarded as the sole criteria – to EU action in regional security. Overly focusing on the ‘speak with one voice’ mantra sometimes leads to stop short of assessing actual outcomes.

Granular computing as a basis of human–data interaction: a cognitive cities use case

The article proposes granular computing as a theoretical, formal and methodological basis for the newly emerging research field of human–data interaction (HDI). We argue that the ability to represent and reason with information granules is a prerequisite for data legibility. As such, it allows for extending the research agenda of HDI to encompass the topic of collective intelligence amplification, which is seen as an opportunity of today’s increasingly pervasive computing environments. As an example of collective intelligence amplification in HDI, we introduce a collaborative urban planning use case in a cognitive city environment and show how an iterative process of user input and human-oriented automated data processing can support collective decision making. As a basis for automated human-oriented data processing, we use the spatial granular calculus of granular geometry.

Mesure de la performance dans les organisations de réadaptation en déficience physique

La présente thèse vise à évaluer le degré d’implantation et d’utilisation de systèmes de mesure de la performance (SMP) par les décideurs des organisations de réadaptation et à comprendre les facteurs contextuels ayant influencé leur implantation. Pour ce faire, une étude de cas multiples a été réalisée comprenant deux sources de données: des entrevues individuelles avec des cadres supérieurs des organisations de réadaptation du Québec et des documents organisationnels. Le cadre conceptuel Consolidated Framework for Implementation Research a été utilisé pour guider la collecte et l’analyse des données. Une analyse intra-cas ainsi qu’une analyse inter-cas ont été réalisées. Nos résultats montrent que le niveau de préparation organisationnelle à l’implantation d’un SMP était élevé et que les SMP ont été implantés avec succès et utilisés de plusieurs façons. Les organisations les ont utilisés de façon passive (comme outil d’information), de façon ciblée (pour tenter d’améliorer des domaines sous-performants) et de façon politique (comme outil de négociation auprès des autorités gouvernementales). Cette utilisation diversifiée des SMP est suscitée par l’interaction complexe de facteurs provenant du contexte interne propre à chaque organisation, des caractéristiques du SMP, du processus d’implantation appliqué et du contexte externe dans lequel évoluent ces organisations. Au niveau du contexte interne, l’engagement continu et le leadership de la haute direction ont été décisifs dans l’implantation du SMP de par leur influence sur l’identification du besoin d’un SMP, l’engagement des utilisateurs visés dans le projet, la priorité organisationnelle accordée au SMP ainsi que les ressources octroyées à son implantation, la qualité des communications et le climat d’apprentissage organisationnel. Toutefois, même si certains de ces facteurs, comme les ressources octroyées à l’implantation, la priorité organisationnelle du SMP et le climat d’apprentissage se sont révélés être des barrières à l’implantation, ultimement, ces barrières n’étaient pas suffisamment importantes pour entraver l’utilisation du SMP. Cette étude a également confirmé l’importance des caractéristiques du SMP, particulièrement la perception de qualité et d’utilité de l’information. Cependant, à elles seules, ces caractéristiques sont insuffisantes pour assurer le succès d’implantation. Cette analyse d’implantation a également révélé que, même si le processus d’implantation ne suit pas des étapes formelles, un plan de développement du SMP, la participation et l’engagement des décideurs ainsi que la désignation d’un responsable de projet ont tous facilité son implantation. Cependant, l’absence d’évaluation et de réflexion collective sur le processus d’implantation a limité le potentiel d’apprentissage organisationnel, un prérequis à l’amélioration de la performance. Quant au contexte externe, le soutien d’un organisme externe s’est avéré un facilitateur indispensable pour favoriser l’implantation de SMP par les organisations de réadaptation malgré l’absence de politiques et incitatifs gouvernementaux à cet effet. Cette étude contribue à accroître les connaissances sur les facteurs contextuels ainsi que sur leurs interactions dans l’utilisation d’innovations tels les SMP et confirme l’importance d’aborder l’analyse de l’implantation avec une perspective systémique.

Les approches de synthèse exploratoire dans le domaine de la santé

Contexte: Les approches de synthèse exploratoire (ou scoping studies) font actuellement l’objet de confusion dans leur appellation, définition et but. Elles continuent aussi de manquer de description méthodologique suffisante ou de détails sur le processus de l’analyse de données. Objectif : Cette synthèse exploratoire fait le point des connaissances sur les approches de synthèse exploratoire utilisées en santé. Plus spécifiquement, ses objectifs sont : 1) d’examiner le volume et l’étendue des synthèses exploratoires ainsi que les domaines d’étude dans lesquels elles ont été conduites; 2) de faire l’inventaire de leurs définitions, buts, forces et faiblesses; et 3) et de faire l’inventaire des approches méthodologiques existantes. Méthodes : Une recherche systématique des synthèses exploratoires a été entreprise jusqu’en avril 2014 dans les bases de données Medline, PubMed, ERIC, PsycINFO, CINAHL, EMBASE, EBM Reviews/Cochrane. Des critères d’inclusion et d’exclusion ont été appliqués afin de ne retenir que des études de langue française et anglaise présentant des définitions, méthodes et écarts de connaissances sur les synthèses exploratoires, ainsi que celles les comparant à d’autres types de revues de littérature. Deux reviseurs ont examiné de façon indépendante les références pertinentes. Une grille d’extraction des données a été conçue afin de recueillir pour chacune des études, les données contextuelles, les étapes méthodologiques ainsi que les définitions, buts et limites des synthèses exploratoires. Les données ont été répertoriées et classées afin de dresser un portrait global des approches de synthèses exploratoires dans un format narratif et tabulaire. Résultats : Sur deux cent cinquante-deux références identifiées, quatre-vingt-douze références pertinentes ont été retenues. Les synthèses exploratoires ont été publiées par 6 pays dans 10 domaines d’études et 73 journaux. Elles ont pour finalité d’être à la fois un support aux connaissances, une aide à la décision et un préalable à une revue systématique de littérature. Cinq auteurs ont été cités en référence et huit autres ont publié sur leur méthodologie. Elles ont 3 étapes importantes de réalisation dont la revue de littérature, la consultation des parties prenantes et la synthèse globale avec ou sans validation des résultats. Les synthèses exploratoires utilisent une méthode systématique, pas toujours exhaustive et sans évaluation formelle des études incluses Des notions claires portant sur leur définition, buts, forces et faiblesses ont été identifiées. Conclusion : Nous suggérons que de nouvelles études soient entreprises afin d’asseoir complètement cette méthode et dégager des lignes directrices pour les chercheurs qui s’y intéresseront.

Geochemistry of Early Toarcian carbonates

The Early Toarcian was characterized by two large perturbations to the carbon cycle: a positive trend associated with increased organic matter burial and ocean anoxia, and a pronounced negative carbon isotope excursion (CIE). We contrast the geochemical evolution in the carbonate phases of two successions: one from the Paris Basin (Sancerre core, comprising black shales), the other from the Lusitanian Basin (Peniche section with very minor lithological expression of bottom water anoxia). Our aim was to identify whether these carbon cycle perturbations were related, and differentiate between the common (global) versus regional expressions of the biogeochemical response and ocean chemistry. Our results highlight contrasts in timing of different phases of anoxia in both locations through the widely documented negative CIE. Widespread anoxic conditions were not a necessary prerequisite for generating a pronounced CIE, as required by the recycling (so-called "Küspert") model. The production of carbonate simultaneously dropped during the d13C negative shift in both locations, likely in response to lowered seawater saturation rate induced by substantial absorption of CO2 from the atmosphere. The recovery interval was accompanied by a rapid reestablishment of seawater alkalinity, and primary and carbonate productivity in epicontinental seas, as evidenced by high d13C and Sr/Ca, in contrast with the more open ocean regime in the Lusitanian Basin. Our results confirm that parallels can be draw between the ocean productivity response and feedback during the Toarcian CIE and the PETM. Both events are characterized by ocean acidification and reduced pelagic calcification followed by a peak in nearshore coccolith productivity, which could have helped the recovery from the perturbation.

Impact of root and shoot temperature on bud dormancy and floral induction in lychee (Litchi chinensis Sonn.)

Potted lychee trees (cv. Tai so) with mature vegetative flushes were grown under three day/night temperature regimes known to induce floral (18/13degreesC), intermediate (23/18degreesC) and vegetative (28/23degreesC) shoot structures. Heating roots respective to shoots accelerated bud-break and shoot emergence, but reduced the level of floral initiation in emergent shoots. At 18/13degreesC, root temperatures of 20 and 25degreesC decreased the period of shoot dormancy from 9 weeks to 5 and 3 weeks, respectively. A root temperature of 20degreesC also increased the proportion of both leafy and stunted panicles to normal leafless panicles, and reduced the number of axillary panicles accompanying each terminal particle. A root temperature of 25degreesC produced only vegetative shoots. At 23/18degreesC, heating roots increased the proportion of vegetative shoots and partially emerged buds to leafy and stunted particles as well as accelerating bud-break. Cooling of roots in relation to the shoot resulted in non-emergence of buds at both 28/23 and 23/18degreesC. Bud-break did not occur until root cooling was terminated and root temperature returned to that of the shoot. At 23/18degreesC, subsequent emergent shoots had a greater proportion of leafy panicles relative to control trees. At 28/23degreesC, all emergent shoots remained vegetative. Lychee floral initiation is influenced by both root and shoot temperature. Root temperature has a direct effect on the length of the shoot dormancy period, with high temperatures reducing this period and the subsequent level of floral initiation. However, an extended period of dormancy in itself is not sufficient for floral initiation, with low shoot temperatures also a necessary prerequisite. (C) 2003 Elsevier B.V. All rights reserved.

Comparative proteomic analysis of GS-NSO murine myeloma cell lines with varying recombinant monoclonal antibody production rate

We have employed an inverse engineering strategy based on quantitative proteome analysis to identify changes in intracellular protein abundance that correlate with increased specific recombinant monoclonal antibody production (qMab) by engineered murine myeloma (NSO) cells. Four homogeneous NSO cell lines differing in qMab were isolated from a pool of primary transfectants. The proteome of each stably transfected cell line was analyzed at mid-exponential growth phase by two-dimensional gel electrophoresis (2D-PAGE) and individual protein spot volume data derived from digitized gel images were compared statistically. To identify changes in protein abundance associated with qMab clatasets were screened for proteins that exhibited either a linear correlation with cell line qMab or a conserved change in abundance specific only to the cell line with highest qMab. Several proteins with altered abundance were identified by mass spectrometry. Proteins exhibiting a significant increase in abundance with increasing qMab included molecular chaperones known to interact directly with nascent immunoglobulins during their folding and assembly (e.g., BiP, endoplasmin, protein disulfide isomerase). 2D-PAGE analysis showed that in all cell lines Mab light chain was more abundant than heavy chain, indicating that this is a likely prerequisite for efficient Mab production. In summary, these data reveal both the adaptive responses and molecular mechanisms enabling mammalian cells in culture to achieve high-level recombinant monoclonal antibody production.

Increased diagnosis of primary aldosteronism, including surgically correctable forms, in centers from five continents

Primary aldosteronism (PA) is a common form of endocrine hypertension previously believed to account for less than 1% of hypertensive patients. Hypokalemia was considered a prerequisite for pursuing diagnostic tests for PA. Recent studies applying the plasma aldosterone/plasma renin activity ratio (ARR) as a screening test have reported a higher prevalence. This study is a retrospective evaluation of the diagnosis of PA from clinical centers in five continents before and after the widespread use of the ARR as a screening test. The application of this strategy to a greater number of hypertensives led to a 5- to 15-fold increase in the identification of patients affected by PA. Only a small proportion of patients ( between 9 and 37%) were hypokalemic. The annual detection rate of aldosterone-producing adenoma (APA) increased in all centers ( by 1.3-6.3 times) after the wide application of ARR. Aldosterone-producing adenomas constituted a much higher proportion of patients with PA in the four centers that employed adrenal venous sampling ( 28 - 50%) than in the center that did not (9%). In conclusion, the wide use of the ARR as a screening test in hypertensive patients led to a marked increase in the detection rate of PA. Copyright © 2004 by The Endocrine Society

Pretend play, mirror self-recognition and imitation: A longitudinal investigation through the second year

The aim in the current study was to investigate the emergence of pretend play, mirror self-recognition, synchronic imitation and deferred imitation in normally developing human infants. A longitudinal study was conducted with 98 infants seen at three-monthly intervals from 12 through to 24 months of age. At each session the infants were tested on a range of tasks assessing the four target skills. Deferred imitation was found to emerge prior to synchronic imitation, pretend play and mirror self-recognition. In contrast, the latter three skills emerged between 18 and 21 months and followed similar developmental trajectories. Deferred imitation was found to hold a prerequisite relation with these three skills. Synchronic imitation, pretend play and mirror self-recognition were not closely associated and no prerequisite relations were found between these skills. These findings are discussed in the context of current theories regarding the development of pretend play, mirror self-recognition, synchronic imitation and deferred imitation in the second year.
