The Political Communication of Independent Regulatory Agencies

Since independent regulatory agencies (IRAs) became key actors in European regulatory governance in the 1990s, a significant share of policy-making has been carried out by organizations that are neither democratically elected nor directly accountable to elected politicians. In this context, public communication plays an important role. On the one hand, regulatory agencies might try to use communication to raise their accountability and thereby to mitigate their democratic deficit. On the other hand, communication may be used with the intent to steer the behavior of the regulated industry when more coercive regulatory means are unfeasible or undesirable. However, empirical research focusing directly on how regulators communicate is virtually non-existent. To fill this gap, this paper examines the public communication of IRAs in four countries (the United Kingdom, Germany, Ireland, and Switzerland) and three sectors (financial services, telecommunications, and broadcasting). The empirical analysis, based on qualitative interviews and a quantitative content analysis, indicates that the organization of the communication function follows a national pattern approach while a policy sector approach is helpful for understanding the use of communication as a soft tool of regulation.

Transnational private authority and the participation of workers' organizations in the regulatory space surrounding the employment relationship

Most corporate codes of conduct and multi-stakeholder sustainability standards guarantee workers' rights to freedom of association and collective bargaining, but many authors are sceptical about the concrete impact of codes and standards of this kind. In this paper we use Hancher and Moran's (1998) concept of 'regulatory space' to assess the potential of private transnational regulation to support the growth of trade union membership and collective bargaining relationships, drawing on some preliminary case study results from a project on the impact of the International Finance Corporation's (IFC) social conditionality on worker organization and social dialogue. One of the major effects of neoliberal economic and industrial policy has been the routine exclusion of workers' organizations from regulatory processes on the grounds that they introduce inappropriate 'political' motives into what ought to be technical decision-making processes. This, rather than any direct attack on their capacity to take action, is what seems best to explain the global decline in union influence (Cradden 2004; Howell 2007; Howe 2012). The evidence we present in the paper suggests that private labour regulation may under certain conditions contribute to a reversal of this tendency, re-establishing the legitimacy of workers' organizations within regulatory processes and by extension the legitimacy of their use of economic and social power. We argue that guarantees of freedom of association and bargaining rights within private regulation schemes are effective to the extent that they can be used by workers' organizations in support of a claim for access to the regulatory space within which the terms and conditions of the employment relationship are determined. Our case study evidence shows that certain trade unions in East Africa have indeed been able to use IFC and other private regulation schemes as levers to win recognition from employers and to establish collective bargaining relationships. Although they did not attempt to use formal procedures to make a claim for the enforcement of freedom of association rights on behalf of their members, the unions did use enterprises' adherence to private regulation schemes as a normative point of reference in argument and political exchange about worker representation. For these unions, the regulation was a useful addition to the range of arguments that they could deploy as means to justify their demand for recognition by employers. By contrast, the private regulation that helps workers' organizations to win access to regulatory processes does little to ensure that they are able to participate meaningfully, whether in terms of technical capacity or of their ability to mobilize social power as a counterweight to the economic power of employers. To the extent that our East African unions were able to make an impact on terms and conditions of employment via their participation in regulatory space it was solely on the basis of their own capacities and resources and the application of national labour law.

Can Charisma Be Taught? Tests of Two Interventions

We tested whether we could teach individuals to behave more charismatically, andwhether changes in charisma affected leader outcomes. In Study 1, a mixed-design fieldexperiment, we randomly assigned 34 middle-level managers to a control or anexperimental group. Three months later, we reassessed the managers using theircoworker ratings (Time 1 raters = 343; Time 2 raters = 321). In Study 2, a within-subjectslaboratory experiment, we videotaped 41 MBA participants giving a speech. We thentaught them how to behave more charismatically, and they redelivered the speech6 weeks later. Independent assessors (n = 135) rated the speeches. Results from thestudies indicated that the training had significant effects on ratings of leader charisma(mean D = .62) and that charisma had significant effects on ratings of leaderprototypicality and emergence................................................................................................................................

Control of gene expression in melanocytes and RPE by conserved distal regulatory elements

Résumé Durant le développement embryonnaire, les cellules pigmentaires des mammifères se développent à partir de deux origines différentes : les melanocytes se développent à partir de la crête neurale alors que les cellules de la rétine pigmentaire (RP) ont une origine neuronale. Un grand nombre de gènes sont impliqués dans la pigmentation dont les gènes de la famille tyrosinase à savoir Tyr, Tyrp1 et Dct. Certaines études ont suggéré que les gènes de la pigmentation sont régulés de manière différentielle dans les mélanocytes et dans la RP. Dans ce travail, les gènes de la famille tyrosinase ont été étudiés comme modèle de la régulation des gènes de la pigmentation par des éléments régulateurs agissant à distance. II a été montré que le promoteur du gène Tyrp1pouvait induire l'expression d'un transgène uniquement dans la RP alors que ce gène est aussi exprimé dans les mélanocytes comme le montre le phénotype des souris mutantes pour Tyrp1. Ce résultat suggère que les éléments régulateurs du promoteur sont suffisants pour l'expression dans la RP mais pas pour l'expression dans les mélanocytes. J'ai donc cherché à identifier la séquence qui régule l'expression dans les mélanocytes. Un chromosome artificiel bactérien (CAB) contenant le gène Tyrp1 s'est avéré suffisant pour induire l'expression dans les mélanocytes, comme démontré par la correction du phénotype mutant. La séquence de ce CAB contient plusieurs régions très conservées qui pourraient représenter de nouveaux éléments régulateurs. Par la suite, j'ai focalisé mon analyse sur une séquence située à -I5 kb qui s'est révélée être un amplificateur spécifique aux mélanocytes comme démontré par des expériences de cultures cellulaire et de transgenèse. De plus, une analyse poussée de cet élément a révélé que le facteur de transcription Sox 10 représentait un transactivateur de cet amplificateur. Comme pour Tyrp1, la régulation du gène tyrosinase est contrôlée par différents éléments régulateurs dans les mélanocytes et la RP. Il a été montré que le promoteur de tyrosinase n'était pas suffisant pour une forte expression dans les mélanocytes et la RP. De plus, l'analyse de la région située en amont a révélé la présence d'un amplificateur nécessaire à l'expression dans les mélanocytes à la position -15 kb. Cet amplificateur n'est toutefois pas actif dans la RP mais agit comme un répresseur dans ces cellules. Ces résultats indiquent que certains éléments nécessaires à l'expression dans les deux types de cellules pigmentaires sont absents de ces constructions. Comme pour Tyrp1, j'ai en premier lieu démontré qu'un CAB était capable de corriger le phénotype albinique, puis ai inséré un gène reporter (lacZ) dans le CAB par recombinaison homologue et ai finalement analysé l'expression du reporter en transgenèse. Ces souris ont montré une expression forte du lacZ dans les mélanocytes et la RP, ce qui indique que le CAB contient les séquences régulatrices nécessaires à l'expression correcte de tyrosinase. Afin de localiser plus précisément les éléments régulateurs, j'ai ensuite généré des délétions dans le CAB et analysé l'expression du lacZ en transgenèse. La comparaison de séquences génomiques provenant de différentes espèces a permis par la suite d'identifier des régions représentant de nouveaux éléments régulateurs potentiels. En utilisant cette approche, j'ai identifié une région qui se comporte comme un amplificateur dans la RP et qui est nécessaire à l'expression de tyrosinase dans ce tissu. De plus, j'ai identifié les facteurs de transcription Mitf et Sox10 comme transactivateurs de l'amplificateur spécifique aux mélanocytes situé à -15 kb. L'identification et la caractérisation des ces éléments régulateurs des gènes tyrosinase et Tyrp1confirme donc que la régulation différentielle des gènes dans les mélanocytes et la RP est liée à des éléments régulateurs séparés. Summary Pigment cells of mammals originate from two different lineages: melanocytes arise from the neural crest, whereas cells of the retinal pigment epithelium (RPE) originate from the optic cup of the developing forebrain. A large set of genes are involved in pigmentation, including the members of the tyrosinase gene family, namely tyrosinase, Tyrp1 and Dct. Previous studies have suggested that pigmentation genes are differentially regulated in melanocytes and RPE. In this work, the tyrosinase gene family was used as a model for studying the involvement of distal regulatory elements in pigment cell-specific gene expression. The promoter of the Tyrp1 gene has been shown to drive detectable transgene expression only to the RPE, even though the gene is also expressed in melanocytes as evident from Tyrp1-mutant mice. This indicates that the regulatory elements responsible for Tyrp1 gene expression in the RPE are not sufficient for expression in melanocytes. I thus searched for a putative melanocyte-specific regulatory sequence and demonstrate that a bacterial artificial chromosome (BAC) containing the Tyrp1 gene and surrounding sequences is able to target transgenic expression to melanocytes and to rescue the Tyrp1 b (brown) phenotype. This BAC contains several highly conserved non-coding sequences that might represent novel regulatory elements. I further focused on a sequence located at -15 kb which I identified as amelanocyte-specific enhancer as shown by cell culture and transgenic mice. In addition, further functional analysis identified the transcription factor Sox10 as being able to bind and transactivate this enhancer. As for Tyrp1, tyrosinase gene regulation is mediated by different cis-regulatory elements in melanocytes and RPE. It was shown that the tyrosinase promoter was not sufficient to confer strong and specific expression in melanocytes and RPE. Moreover, analysis of tyrosinase upstream sequence, revealed the presence of a specific enhancer at position -15 kb which was necessary to confer strong expression in melanocytes. This enhancer element however failed to act as an enhancer in the RPE, but rather repressed expression. This indicates that some regulatory elements required for tyrosinase expression in both RPE and melanocytes are still missing from these constructs. As for Tyrp1, I first demonstrated that a BAC containing the Tyr gene is able to rescue the Tyr c (albino) phenotype in mice, then I inserted a lacZ reporter gene in the BAC by homologous recombination, and finally analysed the pattern of lacZ expression in transgenic mice. These mice showed strong lacZ expression in both RPE and melanocytes, indicating that the BAC contains the regulatory sequences required for proper tyrosinase expression. In order to localize more precisely these regulatory elements, I have then generated several deletions in the BAC and analysed lacZ expression in transgenic mice. Multi-species comparative genomic analysis then allowed identifying conserved sequences that potentially represent novel regulatory elements. Using this experimental approach, I identified a region that behaves as a RPE-specific enhancer and that is required for tyrosinase expression in the retina] pigment epithelium. In addition, I identified the transcription factors Mitf and Sox l0 as being transactivators of the melanocyte-specific enhancer located at -l5 kb. The identification and characterization of these tyrosinase and Tyrp1 distal regulatory element supports the idea that separate regulatory sequences mediate differential gene expression in melanocytes and RPE.

Transplantation tolerance: Clinical potential of regulatory T cells.

The major challenge in transplantation medicine remains long-term allograft acceptance, with preserved allograft function under minimal chronic immunosuppression. To safely achieve the goal of sustained donor-specific T and B cell non-responsiveness, research efforts are now focusing on therapies based on cell subsets with regulatory properties. In particular the transfusion of human regulatory T cells (Treg) is currently being evaluated in phase I/II clinical trials for the treatment of graft versus host disease following hematopoietic stem cell transplantation, and is also under consideration for solid organ transplantation. The purpose of this review is to recapitulate current knowledge on naturally occurring as well as induced human Treg, with emphasis on their specific phenotype, suppressive function and how these cells can be manipulated in vitro and/or in vivo for therapeutic purposes in transplantation medicine. We highlight the potential but also possible limitations of Treg-based strategies to promote long-term allograft survival. It is evident that the bench-to-beside translation of these protocols still requires further understanding of Treg biology. Nevertheless, current data already suggest that Treg therapy alone will not be sufficient and needs to be combined with other immunomodulatory approaches in order to induce allograft tolerance.

Increasing prehospital emergency medical service interventions for nursing home residents.

QUESTION: In the ageing European population, the proportion of interventions by the emergency medical services (EMS) for elderly patients is increasing, but little is known about the recent trend of EMS interventions in nursing homes. The aim of this analysis was to describe the evolution of the incidence of requests for prehospital EMS interventions for nursing home residents aged 65 years and over between 2004 and 2013. METHODS: A prospective population-based register of routinely collected data for each EMS intervention in the Canton of Vaud. Linear time trends of incidence of requests to the EMS in nursing homes were calculated and stratified by age categories. RESULTS: The number of ambulance interventions in nursing homes for people aged 65 years and over (65+) increased by 68.9% (1124‒1898) between 2004 and 2013. A significant linear increase of the annual incidence of requests to EMS per 1,000 nursing home residents was found for people aged 65-79 (10.2, 95% confidence interval [CI] 6.2-14.2), 80-89 (16.5, 95% CI 14.0-19.0) and over 90 (12.1, 95% CI 5.8-18.4). EMS interventions in nursing home residents who required an emergency physician increased during the same period by 205.6% (from 106 to 324), representing an increase from 2% to 7% of all emergency physician interventions in the Canton. CONCLUSIONS: Our results confirmed an important increase in the incidence of EMS interventions in nursing homes during the last decade, far exceeding the actual increase of the nursing home population during the same period. This evolution represents an important opportunity to reconsider the EMS missions in the context of an ageing society.

Solution scanning as a key policy tool: identifying management interventions to help maintain and enhance regulating ecosystem services

The major task of policy makers and practitioners when confronted with a resource management problem is to decide on the potential solution(s) to adopt from a range of available options. However, this process is unlikely to be successful and cost effective without access to an independently verified and comprehensive available list of options. There is currently burgeoning interest in ecosystem services and quantitative assessments of their importance and value. Recognition of the value of ecosystem services to human well-being represents an increasingly important argument for protecting and restoring the natural environment, alongside the moral and ethical justifications for conservation. As well as understanding the benefits of ecosystem services, it is also important to synthesize the practical interventions that are capable of maintaining and/or enhancing these services. Apart from pest regulation, pollination, and global climate regulation, this type of exercise has attracted relatively little attention. Through a systematic consultation exercise, we identify a candidate list of 296 possible interventions across the main regulating services of air quality regulation, climate regulation, water flow regulation, erosion regulation, water purification and waste treatment, disease regulation, pest regulation, pollination and natural hazard regulation. The range of interventions differs greatly between habitats and services depending upon the ease of manipulation and the level of research intensity. Some interventions have the potential to deliver benefits across a range of regulating services, especially those that reduce soil loss and maintain forest cover. Synthesis and applications: Solution scanning is important for questioning existing knowledge and identifying the range of options available to researchers and practitioners, as well as serving as the necessary basis for assessing cost effectiveness and guiding implementation strategies. We recommend that it become a routine part of decision making in all environmental policy areas.

Percutaneous coronary interventions prior to coronary artery bypass surgery.

BACKGROUND AND AIM OF THE STUDY: Percutaneous coronary interventions (PCI) are frequently performed before coronary artery bypass graft (CABG) surgery. This study sought to evaluate postoperative outcomes, and incidence of recurrent target ischemia in vessels with prior PCI in patients who had PCI prior to CABG compared to only CABG patients. METHODS: A review included CABG patients operated from 2000 to 2012. PCI prior to CABG patients were compared with patients having had CABG on native coronary arteries. Demographic and risk factors, including hospital morbidity, mortality, and recurrent target vessel ischemia at follow-up (FU), were compared. Major end-points were statistical differences of postoperative morbidity and reintervention rates due to symptomatic graft failure or target vessel ischemia during FU. RESULTS: Twenty-four percent of 1669 isolated CABG patients had PCI prior to CABG, with an increasing percentage during recent years. Demographics, risk factors, comorbidities and mortality rates were similar. Incidence of postoperative hemorrhage (OR 1.9; 95% CI 1.1-3.2; p = 0.02), perioperative myocardial infarction rate (p = 0.02), neurological deficits (OR 3.5; 95% CI 1.2-9.7; p = 0.02) and re-intervention rate for symptomatic graft or target vessel occlusion were higher in pretreated patients (OR 1.8; 95% CI 1.1-3.0; p = 0.01). CONCLUSIONS: PCI prior to CABG increases the risk for postoperative morbidity. Increased postoperative hemorrhage could be attributed to ongoing double anti-platelet therapy. doi: 10.1111/jocs.12514 (J Card Surg 2015;30:313-318).

CD103 marks a subset of human CD34(+)-derived langerin(+) dendritic cells that induce T-regulatory cells via indoleamine 2,3-dioxygenase-1.

Indoleamine 2,3-dioxygenase 1 (IDO1) is an immunosuppressive molecule expressed in some subsets of normal and neoplastic cells. Mature human dendritic cells (DCs) have been shown to express IDO1, but little is known about its expression and function during DC differentiation from bone marrow hematopoietic stem/progenitor cells (HSPCs). Here, we show that during in vitro differentiation along the myeloid DC lineage, CD34(+) HSPCs acquire IDO1 expression, which acts in a tolerogenic manner by inducing a population of fully functional CD4(+)CD25(+) FOXP3(+) T-regulatory cells. Phenotypically, CD1a(+)CD14(-) HPSC-derived DCs expressed IDO1, langerin, CD11b, and CD1c. Cell-sorting experiments demonstrated that IDO1 expression is found in a subset of CD1a(+)CD14(-)langerin(+) cells, expressing CD103, which is capable of inducing T-regulatory cells in an IDO1-dependent manner. In conclusion, DC differentiation from CD34(+) HSPCs results in the expression of a functionally active IDO1 protein in CD1a(+)langerin(+), CD103-expressing DCs. These data point toward IDO1 expression as part of a tolerogenic signature during DC development.
