Older People's Commissioner for Wales - Annual Review 08/09 putting older people at our heart

The role of Older People's Commissioner for Wales was created with a range of powers to help improve the lives of older people in Wales. This is the first Commission of its kind. Many groups and individuals worked to bring this independent post into being, and the Commissioner's powers reflect their serious intent to challenge the barriers and discrimination that face older people.

Strength and limitations of regulatory T Cells for immunotherapy in transplantation.

In many experimental models, CD4+CD25+Foxp3+ regulatory T cells (nTreg) have been identifi ed as key players in promoting peripheral transplantation (Tx) tolerance. We have been focusing on therapies based on antigen-specifi c nTreg that can control effector T cells (Teff) and prevent allograft rejection. The use of nTreg in immunotherapeutic protocols for solid organ Tx is however limited by their overall low numbers as well as the low precursor frequency of alloantigen cross-reactive nTreg expected to be found in a normal individual. Moreover, although we previously described robust protocols to generate and expand antigen-specifi c nTreg in vitro, the process requires careful selection of highly pure nTreg and cumbersome ex-vivo manipulations, rendering this strategy not easily applicable in clinical solid organ Tx. In this study, we aimed to expand Treg directly in vivo and determine their suppressive function, effi cacy and stability in promoting donor-specifi c tolerance in a stringent murine Tx model. Our data suggest that IL-2-based therapies lead to a signifi cant increase of Treg in vivo. The expanded Treg suppressed Teff proliferation (albeit slightly less effi ciently than nTreg isolated from control mice) and allowed prolonged graft survival of major MHC-mismatched skin grafts in wild-type non-lymphopenic recipients. The expanded Treg alone were however not suffi cient to induce tolerance in stringent experimental conditions. Rapamycin reduced the frequency of Teff but did not impede expansion of Treg. Pro-infl ammatory stimuli hindered the expansion of Treg and resulted in an increase in the frequency of CD4+IFN-γ+ and CD4+IL17+ T cells. We propose that IL-2-based treatments would be an effi cient method for expanding functional Treg in vivo without affecting other immune cell populations, thereby favorably shifting the pool of alloreactive T cells towards regulation in response to an allograft. However, we also highlight some potential limitations of Treg expansion such as concomitant infl ammatory events.

Pandemic influenza control in Europe and the constraints resulting from incoherent public health laws.

Background With the emergence of influenza H1N1v the world is facing its first 21st century global pandemic. Severe Acute Respiratory Syndrome (SARS) and avian influenza H5N1 prompted development of pandemic preparedness plans. National systems of public health law are essential for public health stewardship and for the implementation of public health policy[1]. International coherence will contribute to effective regional and global responses. However little research has been undertaken on how law works as a tool for disease control in Europe. With co-funding from the European Union, we investigated the extent to which laws across Europe support or constrain pandemic preparedness planning, and whether national differences are likely to constrain control efforts. Methods We undertook a survey of national public health laws across 32 European states using a questionnaire designed around a disease scenario based on pandemic influenza. Questionnaire results were reviewed in workshops, analysing how differences between national laws might support or hinder regional responses to pandemic influenza. Respondents examined the impact of national laws on the movements of information, goods, services and people across borders in a time of pandemic, the capacity for surveillance, case detection, case management and community control, the deployment of strategies of prevention, containment, mitigation and recovery and the identification of commonalities and disconnects across states. Results Results of this study show differences across Europe in the extent to which national pandemic policy and pandemic plans have been integrated with public health laws. We found significant differences in legislation and in the legitimacy of strategic plans. States differ in the range and the nature of intervention measures authorized by law, the extent to which borders could be closed to movement of persons and goods during a pandemic, and access to healthcare of non-resident persons. Some states propose use of emergency powers that might potentially override human rights protections while other states propose to limit interventions to those authorized by public health laws. Conclusion These differences could create problems for European strategies if an evolving influenza pandemic results in more serious public health challenges or, indeed, if a novel disease other than influenza emerges with pandemic potential. There is insufficient understanding across Europe of the role and importance of law in pandemic planning. States need to build capacity in public health law to support disease prevention and control policies. Our research suggests that states would welcome further guidance from the EU on management of a pandemic, and guidance to assist in greater commonality of legal approaches across states.

After Satan : Essays in Honour of Neil Forsyth

This volume is the result of a collective desire to pay homage to Neil Forsyth, whose work has significantly contributed to scholarship on Satan. This volume is "after" Satan in more ways than one, tracing the afterlife of both the satanic figure in literature and of Neil Forsyth's contribution to the field, particularly in his major books The Old Enemy: Satan and the Combat Myth (Princeton University Press, 1987, revised 1990) and The Satanic Epic (Princeton University Press, 2003). The essays in this volume draw on Forsyth's work as a focus for their analyses of literary encounters with evil or with the Devil himself, reflecting the richness and variety of contemporary approaches to the age-old question of how to represent evil. All the contributors acknowledge Neil Forsyth's influence in the study of both the Satan-figure and Milton's Paradise Lost. But beyond simply paying homage to Neil Forsyth, the articles collected here trace the lineage of the Satan figure through literary history, showing how evil can function as a necessary other against which a community may define itself. They chart the demonised other through biblical history and medieval chronicle, Shakespeare and Milton, to nineteenth-century fiction and the contemporary novel. Many of the contributors find that literary evil is mediated through the lens of the Satan of Paradise Lost, and their articles address the notion, raised by Neil Forsyth in The Satanic Epic, that the literary Devil-figures under consideration are particularly interested in linguistic ambivalence and the twisted texture of literary works themselves. The multiple responses to evil and the continuous reinvention of the devil figure through the centuries all reaffirm the textual presence of the Devil, his changing forms necessarily inscribed in the shifting history of western literary culture. These essays are a tribute to the work of Neil Forsyth, whose scholarship has illuminated and guided the study of the Devil in English and other literatures.

Acid-sensing ion channels : modulation by serine-proteases and involvement in acid-induced action potential generation in hippocampal neurons

SUMMARY Acid-sensing ion channels (ASICs) are non-voltage gated sodium channels. They are activated by rapid extracellular acidification and generate an inactivating inward current. Four ASIC genes have been cloned: ASIC1, 2, 3 and 4, with variants a and b for ASIC1and AS1C2. ASICs are expressed in neurons of the central (CNS) and peripheral nervous system (PNS). In the CNS, ASICs have a role in learning, memory, as well as in neuronal death in ischemia. In the PNS, ASICs are involved in the perception of acid-induced pain, as well as in mechanoperception. In one part of my thesis project, we addressed the question of the mechanism of regulation of ASIC1 a by the serine protease trypsin at the molecular level. Trypsin modifies the function of ASIC1 a but not of ASIC1b. In order to identify the channel region responsible for this effect, we created chimeras between ASIC1 a and 1b. Subsequently, to identify the exact trypsin target(s), we mutated predicted trypsin sites in the region identified by the chimera. In the second part of a project, we investigated the role of ASICs at the cellular level, in neuronal signaling. Using the whole-cell patch clamp in hippocampal neuronal culture, we studied the potential involvement of ASICs in action potential (AP) generation. In the first part of the thesis work, we showed that trypsin modifies ASIC1a function: it shifts the pH activation and the steady-state inactivation curve towards more acidic values and accelerates the time course of the channel recovery from inactivation. We also showed that trypsin cleaves ASIC1a and that the functional effect and a channel cleavage correlate. In the inactivated state, channels cannot be modified by trypsin. Cleavage occurs in a channel region that is also important for inactivation of all ASICs; a part of this region is critical for the inhibition of ASIC1 a by the spider toxin Psalmotoxin1. In the second part of the thesis work, we showed that ASIC activity can modulate AP generation. ASIC activity by itself can induce trains of APs. In situations in which this activity by itself is not sufficient to induce APs, it can contribute to AP generation. During high neuronal activity, ASIC activity can block already existing trains of APs. In conclusion, depending on the activity of neuron in a particular moment, ASICs can differently modulate AP generation; they can induce, facilitate or inhibit APs. We also showed that trypsin changes the capability of ASICs to modulate AP generation by shifting the pH dependence to more acidic values, which adapts channel gating to pH conditions which may occur in pathological conditions such as ischemia. Our finding that trypsin modifies ASIC1 a function identifies a novel pharmacological tool, and proposes a mechanism of ASIC1a regulation that may have a physiological importance. The identification of the exact site of trypsin action gives insight to the molecular mechanisms of ASIC regulation. This work proposes a role in modulation of AP generation for ASICs in the CNS. RESUME Les canaux ASIC sont les canaux ioniques activés par l'acidification rapide extracellulaire. Activés, ils génèrent un courant entrant qui inactive en présence de stimulus acide. Quatre gènes ASIC ont été clonés, ASIC1, 2, 3 et 4, avec les variants a et b pour ASIC1 et 2. Les ASICs sont exprimés dans les neurones du système nerveux central (SNC) et périphérique (SNP). Dans le SNC, les ASIC ont un rôle dans le mémoire, apprentissage et la mort neuronale dans t'ischémie. Dans le SNP, ils ont un rôle dans la perception de la douleur et méchanosensation. Dans une partie de mon projet de thèse, nous avons étudié les mécanismes de la régulation d'ASIC1a par la sérine-protéase trypsine au niveau moléculaire. La trypsine modifie la fonction d'ASIC1a et pas ASIC1b. Nous avons créé les chimères entre ASIC1 a et 1 b, afin d'identifier la région du canal responsable pour l'effet. Pour identifier le(s) site(s) exactes de l'action de la trypsine, nous avons muté les sites potentiels de la trypsine dans la région identifiée par les chimères. Dans la deuxième partie du projet, nous avons étudié le rôle des ASICs au niveau cellulaire. En utilisant la technique du patch clamp dans les cultures des neurones de l'hippocampe, nous avons étudié l'implication des ASICs dans la génération des potentiels d'action (PA). Nous avons montré que la trypsine agit sur le canal ASIC1a ; elle décale l'activation et « steady-state » inactivation vers les valeurs plus acides, et elle raccourcit le temps du « recovery » du canal. La trypsine coupe ASIC1a sur le résidu K145 et l'effet fonctionnel et la coupure corrèlent. Nous avons identifié la région du canal responsable pour l'inactivation de tous les ASICs ; une partie de cette région est responsable pour ['inhibition d'ASIC1 a par la Psalmotoxinel . Nous avons montré que les ASICs peuvent moduler la génération des PAs. L'activité des ASICs peut induire les trains des PAs. Quand l'activité des ASICs n'est pas suffisante pour induire le PA, elle peut contribuer à sa génération. Pendant l'activité neuronale forte, l'activité des ASICs peut bloquer les trains des PAs qui existent déjà. En conclusion, dépendant de l'activité neuronale, les ASICs peuvent moduler la génération des PAs différemment ; ils peuvent induire, faciliter ou inhiber les PAs. La trypsine change la capacité des ASICs de moduler les PAs. Après l'action de la trypsine, les ASICs peuvent moduler la génération des PAs dans les conditions légèrement acides, suivies par les fluctuations du pH acide, qui peuvent exister dans l'ischémie. Le fait que la trypsine agit sur ASIC1a définit l'outil pharmacologique et propose le mécanisme de la régulation d'ASICI a qui pourrait avoir l'importance physiologique. L'identification du site de l'action de la trypsine éclaircit les mécanismes moléculaires de la régulation des ASICs. Cette étude propose un rôle des ASICs dans la modulation de la génération des PAs. Résumé pour le public large Les neurones sont les cellules de système nerveux dont la fonction est la signalisation. Comme toutes les autres cellules, les neurones ont une membrane qui sépare l'intérieur du milieu extérieur. Cette membrane est imperméable pour des particules chargées (ions). Dans cette membrane existent les protéines spécifiques, « canaux », qui permettent le transport des ions d'un côté de la membrane à l'autre, comme réponse aux stimuli différents. Ce transport des ions à travers la membrane génère un courant, qu'on peut mesurer. Ce courant est la base de la communication entre les neurones, ou, ce qu'on appelle la signalisation neuronale. Quand ce courant est suffisamment grand, il permet la génération du potentiel d'action, qui est le message principal de communication neuronale. Les canaux ASIC (acid-sensing ion channel), que nous étudions dans le laboratoire, sont activés par les acides. Les acides sont relâchés dans beaucoup de situations dans le système nerveux. Les ASIC ont été découverts récemment (en 1996), et nous ne connaissons pas encore très bien toutes les fonctions de ces canaux. Nous savons qu'ils ont un rôle dans le mémoire, apprentissage, la sensation de la douleur et l'infarctus cérébral. Dans la première partie de ce projet de thèse, nous avons voulu mieux comprendre comment fonctionnent ces canaux. Pour faire ça, nous avons étudié la régulation des ASICs par une protéine, trypsine, qui coupe le canal ASIC. Nous avons étudié ou exactement la trypsine coupe le canal et quels effets ça produit sur la fonction du canal. Dans la deuxième partie du projet de thèse, nous avons voulu mieux connaître comment le canal fonctionne au niveau de la cellule, comment il interagit avec les autres canaux et si il a un rôle dans la génération des potentiels d'action. Nous avons pu montrer que la trypsine change la fonction du canal, ce qui lui permet de fonctionner différemment. Nous avons aussi déterminé ou exactement ta trypsine coupe le canal. Au niveau de la cellule, nous avons montré que les ASIC peuvent moduler la génération des potentiels d'action, étant, dépendant de l'activité du neurone, soit activateurs, soit inhibiteurs. La trypsine est une molécule qui peut être libérée dans le système nerveux pendant certaines conditions, comme l'infarctus cérébral. A cause de ça, les connaissances que la trypsine agit sur le anal ASIC pourraient être important physiologiquement. La connaissance de l'endroit exacte ou la trypsine coupe le canal nous aide à mieux comprendre la relation structure-fonction du canal. La modulation de la génération des potentiels d'actions par les ASIC indique que ces canaux peuvent avoir un rôle important dans la signalisation neuronale.

Federalism and Welfare to Work in Switzerland: The Development of Active Social Policies in a Fragmented Welfare State

This article is concerned with the impact that federal structures have on the development of welfare to work or activation policies. More precisely, it argues that the incentives and the risks associated with a division of responsibilities among different jurisdictions may constitute an obstacle to broad reforms that promote labor market participation of nonworking benefit recipients. This argument is illustrated with a case study discussing policy responses to a massive rise in caseloads among social assistance recipients in Switzerland. We conclude that the lack of a fundamental reform was the consequence of the incentives provided by the federal structure of the program. These incentives have both encouraged cost shifting among jurisdictions and discouraged involvement of federal level policy makers in a bigger reform.

Mixed Blessing? EP Oversight of the ESDP and the Constitutional Treaty

As commonly held, the European Security and Defence Policy (ESDP) suffers from a “double democratic deficit”: the EP has a marginal role in the ESDP-making process and the national parliaments remain unable to account for their own government. Therefore pressure coming from these two institutions had been exercised during the Convention on the Future of Europe to improve the democratic oversight on this rapidly evolving policy. This paper investigates the innovations included in the Constitutional Treaty, focusing specifically on the new role granted to the EP. It shows that even though this text does not substantially modify the inter-institutional balance of powers in the ESDP area, the EP may take advantage of some of its articles to become an actor in the ESDP-control process in the ‘living constitution.

The Role of Parliaments in European foreign policy

This book addresses the debate on the democratic deficit of European foreign and defence policies. This debate revolves around two dimensions. The first one has to do with the accountability of CFSP institutions. Is the current degree of parliamentary oversight of these policies the most appropriate? Has the disengagement of national parliaments regarding European foreign policy been counterbalanced by giving sufficient powers to the European Parliament? And, regarding the European Security and Defence Policy (ESDP), are national parliaments effectively controlling it? The second dimension of the debate is related to the wider question of whether the European Parliament is capable of legitimising EU policy outcomes. In the absence of a Europe-wide demos and of a true party system, what interests do Members of the European Parliament (MEPs) represent when dealing with foreign policy issues? Are there transnational cleavages in foreign policy or are they mainly national? Furthermore, is the European Parliament developing a transnational, autonomous stance on foreign policy issues, different from that of the Council or the Commission? The present volume is the result of the 2nd Meeting of the FORNET Working Group on “Evolution and Accountability of CFSP Institutions” organised by the Observatory of European Foreign Policy (Research line of the Institut Universitari d’Estudis Europeus), which took place in Barcelona, the 4 and 5 March 2005.

Equidistribution estimates for Fekete points on complex manifolds

We study the equidistribution of Fekete points in a compact complex manifold. These are extremal point configurations defined through sections of powers of a positive line bundle. Their equidistribution is a known result. The novelty of our approach is that we relate them to the problem of sampling and interpolation on line bundles, which allows us to estimate the equidistribution of the Fekete points quantitatively. In particular we estimate the Kantorovich-Wasserstein distance of the Fekete points to its limiting measure. The sampling and interpolation arrays on line bundles are a subject of independent interest, and we provide necessary density conditions through the classical approach of Landau, that in this context measures the local dimension of the space of sections of the line bundle. We obtain a complete geometric characterization of sampling and interpolation arrays in the case of compact manifolds of dimension one, and we prove that there are no arrays of both sampling and interpolation in the more general setting of semipositive line bundles.

War Signals: A Theory of Trade, Trust and Conflict

We construct a dynamic theory of civil conflict hinging on inter-ethnic trust and trade. The model economy is inhabitated by two ethnic groups. Inter-ethnic trade requires imperfectly observed bilateral investments and one group has to form beliefs on the average propensity to trade of the other group. Since conflict disrupts trade, the onset of a conflict signals that the aggressor has a low propensity to trade. Agents observe the history of conflicts and update their beliefs over time, transmitting them to the next generation. The theory bears a set of testable predictions. First, war is a stochastic process whose frequency depends on the state of endogenous beliefs. Second, the probability of future conflicts increases after each conflict episode. Third, "accidental" conflicts that do not reflect economic fundamentals can lead to a permanent breakdown of trust, plunging a society into a vicious cycle of recurrent conflicts (a war trap). The incidence of conflict can be reduced by policies abating cultural barriers, fostering inter-ethnic trade and human capital, and shifting beliefs. Coercive peace policies such as peacekeeping forces or externally imposed regime changes have instead no persistent effects.

La evaluación entre iguales en el grado de educación social. Aproximación a la vida profesional

La relación educativa entraña, inevitablemente, el debate entorno de la verticalidad y del ejercicio del poder. De qué modo nos relacionamos y cómo gestionamos la comunicación entre educadores y educandos, así como entre iguales. Esa tensión se ve amplificada en la medida que incorporamos lógicas evaluativas en nuestro quehacer profesional. La siguiente comunicación describe la experiencia de la metodología de aprendizaje basada en la evaluación entre iguales aplicada a la profesionalización de los y las educadores/as sociales. Tanto a nivel escolar como en el universitario hay numerosas experiencias publicadas en relación a la metodología de evaluación entre iguales. Además, existen numerosos apartados de los “Documentos profesionalizadores” donde se justifica el hecho de que se entrenen algunas habilidades que deberían darse en la práctica profesional (como por ejemplo en la definición, en el código ético, y en el catálogo de funciones y competencias del/la educador/a social). En esta comunicación pretendemos dar a conocer la experiencia de entrenamiento de futuros educadores en aspectos que tienen una relación directa con la evaluación entre educadores/as sociales. Así pues, utilizaremos una justificación académica y metodológica de la actividad, enlazándola con los documentos profesionalizadores con un fin relacionado directamente con el ejercicio de la profesión.
