Fiscal Federalism at the Ballot Box : The Relevance of Expressive Voting

This paper explores the impact of citizens' motivation to vote on the pattern of fiscal federalism. If the only concern of instrumental citizens was outcome they would have little incentive to vote because the probability that a single vote might change an electoral outcome is usually minuscule. If voters turn out in large numbers to derive intrinsic value from action, how will these voters choose when considering the role local jurisdictions should play? The first section of the paper assesses the weight that expressive voters attach to an instrumental evaluation of alternative outcomes. Predictions are tested with reference to case study analysis of the way Swiss voters assessed the role their local jurisdiction should play. The relevance of this analysis is also assessed with reference to the choice that voters express when considering other local issues. Textbook analysis of fiscal federalism is premised on the assumption that voters register choice just as 'consumers' reveal demand for services in a market, but how robust is this analogy.

The role of the Estrogen-Responsive B box protein in skin morphogenesis, wound repair and skin disease

SUMMARY: EBBP is a poorly characterized member of the RBCC/TRIM family (RING finger B-box coiled-coilltripartite motif). It is ubiquitously expressed, but particularly high levels are found in keratinocytes. There is evidence that EBBP is involved in inflammatory processes, since it can interact with pro-interleukin-1 ß (prolL-1 ß) in human macrophages and keratinocytes, and its downregulation results in reduced secretion of IL-1 ß. IL-1ß activation and secretion requires the proteolytic cleavage of prolL-1ß by caspase-1, which in turn is actìvated by a protein complex called the inflammasome. As it has been demonstrated that EBBP can bind two different proteins of the inflammasome (NALP-1 and caspase 1), we assumed that EBBP plays a role in the regulation of inflammation and that the inflammasome, which has as yet only been described in ínflammatory cells, may also exist in keratinocytes. Indeed, I could show in my thesis that the inflammasome components are expressed in human keratinócytes at the RNA and protein level and also in vivo in human epidermis. After irradiation with a physiological dose of UVB, keratinocytes activated prolL-1ß and secreted prolL-1 a, IL-1 ß, prolL-18 and inflammasome proteins, although all these proteins lack a classical signal peptide. The secretion was dependent on caspase-1 activity, but not on de novo protein synthesis. Knock-down of NALP1 and -3, caspase-1 and -5, EBBP and Asc strongly reduced the secretion of IL-1 ß, demonstrating that also in keratinocytes inflammasome proteins are directly involved in maturation of this cytokine. These results demonstrate for the first time the presence of an active inflammasome in non-professional immune cells. Moreover, they show that UV irradiation is a stimulus for inflammasome activation in keratinocytes. For the analysis of the ín vivo functions of EBBP, transgenic mice overexpressing EBBP in the epidermis were generated. To examine the influence of EBBP overexpression on inflammatory processes, we subjected the mice to different challenges, which induce inflammation. Wound-healing, UVB irradiation and delayed hypersensitivity were tested, but we did not observe any phenotype in the K14-EBBP mice. Besides, a conditional ebbp knockout mouse has been obtained, which will allow to determine the effects of EBBP gene deletion in different tissues and organs. RESUME: EBBP est un membre encore mal connu de la famille des RBCC/TRIM (RING finger B-box coiled-coil/tripartite motif). Il est exprimé de manière ubiquitaire, et en particulier dans les kératinocytes. EBBP étant capable d'interagir avec la prointerleukine-1 ß (prolL-1 ß) dans les macrophages et les kératinocytes humains et de réguler la sécrétion de l'IL-1 ß, il est très probable que cette protéine est impliquée dans l'inflammation. L'activation et la sécrétion de l'IL-1 ß requièrent le clivage protéolytique de son précurseur prolL-1ß par la caspase-1, qui est elle-même activée par un complexe protéique appelé l'inflammasome. Comme il a été démontré qu'EBBP peut lier deux protéines de l'inflammasome (NALP-1 et caspase-1), nous avons émis l'hypothèse qu'EBBP joue un rôle dans la régulation de l'inflammation et que l'inflammasome, jusqu'ici décrit exclusivement dans des cellules inflammatoires, existe dans les kératinocytes. En effet, j'ai pu montrer dans ma thèse que les composants de l'inflammasome sont exprimés dans les kératinocytes humains ainsi que in vivo dans l'épiderme humain. Après irradiation avec une dose, physiologique d'UVB, les kératinocytes activent la prolL-1 ß et sécrètent la prolL-1a, l'IL-1 ß, la prolL-18 et des protéines de l'inflammasome, bien que toutes ces protéines soient dépourvues de peptide signal. La sécrétion dépend de la caspase-1 mais pas de la synthèse protéique de novo. Le knock-down de NALP-1 et -3, des caspase-1 et -5, d'EBBP et d'Asc réduit de manière marquée la sécrétion d'IL-1 ß, démontrant que dans les kératinocytes également, les protéines de l'inflammasome sont impliquées directement dans la maturation de cette cytokine. Ces résultats démontrent pour la première fois la présence d'un inflammasome actif dans des cellules immunitaires non professionnelles. De plus, ils montrent que l'irradiation aux UV est un stimulus pour l'activation de l'inflammasome dans les kératinocytes. Pour l'analyse des fonctions d'EBBP in vivo, nous avons généré des souris transgéniques qui surexpriment EBBP dans l'épiderme. En vue d'examiner l'influence de la surexpression d'EBBP sur le processus inflammatoire, nous avons soumis ces souris à differents modèles d'inflammation. Nous avons testé cicatrisation, UVB et hypersensibilité retardée, mais n'avons pas observé de phénotype chez les souris transgéniques. En parallèle, nous avons également généré des souris knock-out pour ebbp qui devraient nous permettre de déterminer les effets de la suppression d'EBBP dans différents tissus et organes.

Big data and other challenges in the quest for orthologs.

Given the rapid increase of species with a sequenced genome, the need to identify orthologous genes between them has emerged as a central bioinformatics task. Many different methods exist for orthology detection, which makes it difficult to decide which one to choose for a particular application. Here, we review the latest developments and issues in the orthology field, and summarize the most recent results reported at the third 'Quest for Orthologs' meeting. We focus on community efforts such as the adoption of reference proteomes, standard file formats and benchmarking. Progress in these areas is good, and they are already beneficial to both orthology consumers and providers. However, a major current issue is that the massive increase in complete proteomes poses computational challenges to many of the ortholog database providers, as most orthology inference algorithms scale at least quadratically with the number of proteomes. The Quest for Orthologs consortium is an open community with a number of working groups that join efforts to enhance various aspects of orthology analysis, such as defining standard formats and datasets, documenting community resources and benchmarking.

Re-opening the black box in societal metabolism: the application of MuSIASEM to water

In this paper we address the complexity of the analysis of water use in relation to the issue of sustainability. In fact, the flows of water in our planet represent a complex reality which can be studied using many different perceptions and narratives referring to different scales and dimensions of analysis. For this reason, a quantitative analysis of water use has to be based on analytical methods that are semantically open: they must be able to define what we mean with the term “water” when crossing different scales of analysis. We propose here a definition of water as a resource that deal with the many services it provides to humans and ecosystems. WE argue that water can fulfil so many of them since the element has many characteristics that allow for the resource to be labelled with different attributes, depending on the end use –such as drinkable. Since the services for humans and the functions for ecosystems associated with water flows are defined on different scales but still interconnected it is necessary to organize our assessment of water use across different hierarchical levels. In order to do so we define how to approach the study of water use in the Societal Metabolism, by proposing the Water Metabolism, tganized in three levels: societal level, ecosystem level and global level. The possible end uses we distinguish for the society are: personal/physiological use, household use, economic use. Organizing the study of “water use” across all these levels increases the usefulness of the quantitative analysis and the possibilities of finding relevant and comparable results. To achieve this result, we adapted a method developed to deal with multi-level, multi-scale analysis - the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) approach - to the analysis of water metabolism. In this paper, we discuss the peculiar analytical identity that “water” shows within multi-scale metabolic studies: water represents a flow-element when considering the metabolism of social systems (at a small scale, when describing the water metabolism inside the society) and a fund-element when considering the metabolism o ecosystems (at a larger scale when describing the water metabolism outside the society). The theoretical analysis is illustrated using two case which characterize the metabolic patterns regarding water use of a productive system in Catalonia and a water management policy in Andarax River Basin in Andalusia.

Nest-box design for the study of diurnal raptors and owls is still an overlooked point in ecological, evolutionary and conservation studies: a review

The use of artificial nest-boxes has led to significant progress in bird conservation and in our understanding of the functional and evolutionary ecology of free-ranging birds that exploit cavities for roosting and reproduction. Nest-boxes and their improved accessibility have made it easier to perform comparative and experimental field investigations. However, concerns about the generality and applicability of scientific studies involving birds breeding in nest-boxes have been raised because the occupants of boxes may differ from conspecifics occupying other nest sites. Here we review the existing evidence demonstrating the importance of nest-box design to individual life-history traits in three falcon (Falconiformes) and seven owl (Strigiformes) species, as well as the extent to which publications on these birds describe the characteristics of exploited artificial nest-boxes in their 'methods' sections. More than 60% of recent publications did not provide any details on nest-box design (e.g. size, shape, material), despite several calls >15 years ago to increase the reporting of such information. We exemplify and discuss how variation in nest-box characteristics can affect or confound conclusions from nest-box studies and conclude that it is of overall importance to present details of nest-box characteristics in scientific publications.

Accounting for Big City Growth in Low Paid Occupations: Immigration and/or Service Class Consumption

Growth of 'global cities' in the 1980s was supposed to have involved an occupational polarisation, including growth of low paid service jobs. Though held to be untrue for European cities, at the time, some such growth did emerge in London a decade later than first reported for New York. The question is whether there was simply a delay before London conformed to the global city model, or whether another distinct cause was at work in both cases. This paper proposes that the critical factor in both cases was actually an upsurge of immigration from poor countries providing an elastic supply of cheap labour. This hypothesis and its counterpart based on growth in elite jobs are tested econometrically for the British case with regional data spanning 1975-2008, finding some support for both effects, but with immigration from poor countries as the crucial influence in late 1990s London.

Molecular risk assessment of BIG 1-98 participants by expression profiling using RNA from archival tissue.

Background: The purpose of the work reported here is to test reliable molecular profiles using routinely processed formalin-fixed paraffin-embedded (FFPE) tissues from participants of the clinical trial BIG 1-98 with a median follow-up of 60 months. Methods: RNA from fresh frozen (FF) and FFPE tumor samples of 82 patients were used for quality control, and independent FFPE tissues of 342 postmenopausal participants of BIG 1-98 with ER-positive cancer were analyzed by measuring prospectively selected genes and computing scores representing the functions of the estrogen receptor (eight genes, ER_8), the progesterone receptor (five genes, PGR_5), Her2 (two genes, HER2_2), and proliferation (ten genes, PRO_10) by quantitative reverse transcription PCR (qRT-PCR) on TaqMan Low Density Arrays. Molecular scores were computed for each category and ER_8, PGR_5, HER2_2, and PRO_10 scores were combined into a RISK_25 score. Results: Pearson correlation coefficients between FF- and FFPE-derived scores were at least 0.94 and high concordance was observed between molecular scores and immunohistochemical data. The HER2_2, PGR_ 5, PRO_10 and RISK_25 scores were significant predictors of disease free-survival (DFS) in univariate Cox proportional hazard regression. PRO_10 and RISK_25 scores predicted DFS in patients with histological grade II breast cancer and in lymph node positive disease. The PRO_10 and PGR_ 5 scores were independent predictors of DFS in multivariate Cox regression models incorporating clinical risk indicators; PRO_10 outperformed Ki-67 labeling index in multivariate Cox proportional hazard analyses. Conclusions: Scores representing the endocrine responsiveness and proliferation status of breast cancers were developed from gene expression analyses based on RNA derived from FFPE tissues. The validation of the molecular scores with tumor samples of participants of the BIG 1-98 trial demonstrates that such scores can serve as independent prognostic factors to estimate disease free survival (DFS) in postmenopausal patients with estrogen receptor positive breast cancer.

The advantage of letrozole over tamoxifen in the BIG 1-98 trial is consistent in younger postmenopausal women and in those with chemotherapy-induced menopause.

Letrozole, an aromatase inhibitor, is ineffective in the presence of ovarian estrogen production. Two subpopulations of apparently postmenopausal women might derive reduced benefit from letrozole due to residual or returning ovarian activity: younger women (who have the potential for residual subclinical ovarian estrogen production), and those with chemotherapy-induced menopause who may experience return of ovarian function. In these situations tamoxifen may be preferable to an aromatase inhibitor. Among 4,922 patients allocated to the monotherapy arms (5 years of letrozole or tamoxifen) in the BIG 1-98 trial we identified two relevant subpopulations: patients with potential residual ovarian function, defined as having natural menopause, treated without adjuvant or neoadjuvant chemotherapy and age ≤ 55 years (n = 641); and those with chemotherapy-induced menopause (n = 105). Neither of the subpopulations examined showed treatment effects differing from the trial population as a whole (interaction P values are 0.23 and 0.62, respectively). Indeed, both among the 641 patients aged ≤ 55 years with natural menopause and no chemotherapy (HR 0.77 [0.51, 1.16]) and among the 105 patients with chemotherapy-induced menopause (HR 0.51 [0.19, 1.39]), the disease-free survival (DFS) point estimate favoring letrozole was marginally more beneficial than in the trial as a whole (HR 0.84 [0.74, 0.95]). Contrary to our initial concern, DFS results for young postmenopausal patients who did not receive chemotherapy and patients with chemotherapy-induced menopause parallel the letrozole benefit seen in the BIG 1-98 population as a whole. These data support the use of letrozole even in such patients.

Big and Little OER

Much of the attention around OERs has been on institutional projects which make explicit learning content available. These can be classified as 'big OER' but another form of OER is that of small scale, individually produced resources using web 2.0 type services, which are classified as 'little OER'. This paper examines some of the differences between the use of these two types of OER to highlight issues in open education. These include attitudes towards reputation, the intentionality of the resource, models of sustainability, the implicit affordances of resources and the context of their hosting sites.

Perspectives for Forensic Intelligence in anti-doping: thinking outside the box

Today's approach to anti-doping is mostly centered on the judicial process, despite pursuing a further goal in the detection, reduction, solving and/or prevention of doping. Similarly to decision-making in the area of law enforcement feeding on Forensic Intelligence, anti-doping might significantly benefit from a more extensive gathering of knowledge. Forensic Intelligence might bring a broader logical dimension to the interpretation of data on doping activities for a more future-oriented and comprehensive approach instead of the traditional case-based and reactive process. Information coming from a variety of sources related to doping, whether directly or potentially, would feed an organized memory to provide real time intelligence on the size, seriousness and evolution of the phenomenon. Due to the complexity of doping, integrating analytical chemical results and longitudinal monitoring of biomarkers with physiological, epidemiological, sociological or circumstantial information might provide a logical framework enabling fit for purpose decision-making. Therefore, Anti-Doping Intelligence might prove efficient at providing a more proactive response to any potential or emerging doping phenomenon or to address existing problems with innovative actions or/and policies. This approach might prove useful to detect, neutralize, disrupt and/or prevent organized doping or the trafficking of doping agents, as well as helping to refine the targeting of athletes or teams. In addition, such an intelligence-led methodology would serve to address doping offenses in the absence of adverse analytical chemical evidence.
