Long-term outcomes of primarily metastatic juvenile pilocytic astrocytoma in children
Authors: Yecies Derek , Fisher Paul Graham , Cheshier Samuel , Edwards Michael , Grant Gerald 
Published: November 2017

OBJECTIVEPrimarily metastatic juvenile pilocytic astrocytoma (JPA) is rare, likely representing 2%–3% of all cases of JPA. Due to the rarity of primarily metastatic JPA, there is currently no standard treatment paradigm and the long-term outcomes are not fully known. The goal of this case series was to add to the current understanding of this disease process.METHODSThe authors searched a comprehensive database of pediatric patients with brain and spinal cord tumors treated at Lucile Packard Children’s Hospital from 1997 to 2016 and identified 5 patients with primarily metastatic JPA. A retrospective chart review was performed and details of the patients’ treatment and clinical course were recorded for further analysis.RESULTSFor the 5 patients with primarily metastatic JPA, the mean follow-up period was 12.3 years. All patients in our series had biopsies or subtotal resections and upfront treatment. Three patients were treated with chemotherapy alone, one was treated with chemotherapy and radiotherapy, and one was treated with radiotherapy alone. Four patients had stable disease after initial treatment, and one patient had multiple episodes of progressive disease but underwent successful salvage therapy and has had stable disease for 19 years. One patient died of an intracerebral hemorrhage 10 years following initial radiation treatment believed to be secondary to radiation vasculopathy.CONCLUSIONSEvaluation of the entire neuraxis should be performed in all instances of initial JPA diagnosis to properly assess for primarily metastatic disease. Many patients with primarily metastatic JPA will have stable disease after upfront treatment, although the higher rate of stable disease found in this series relative to other reports is likely secondary to the small sample size.

Abstract
We surveyed the core regions of the z = 1.46 cluster XCS J2215.9−1738 with the Atacama Large Millimeter Array (ALMA) and the MUSE-GALACSI spectrograph on the Very Large Telescope (VLT). We obtained high spatial resolution observations with ALMA of the 1.2 mm dust continuum and molecular gas emission in the central regions of the cluster. These observations detect 14 significant millimeter sources in a region with a projected diameter of just ∼500 kpc (∼1′). For six of these galaxies, we also obtain 12CO(2–1) and 12CO(5–4) line detections, confirming them as cluster members, and a further five of our millimeter galaxies have archival 12CO(2–1) detections, which also place them in the cluster. An additional two millimeter galaxies have photometric redshifts consistent with cluster membership, although neither show strong line emission in the MUSE spectra. This suggests that the bulk (≥11/14, ∼80%) of the submillimeter sources in the field are in fact luminous infrared galaxies lying within this young cluster. We then use our sensitive new observations to constrain the dust-obscured star formation activity and cold molecular gas within this cluster. We find hints that the cooler dust and gas components within these galaxies may have been influenced by their environment, reducing the gas reservoir available for their subsequent star formation. We also find that these actively star-forming galaxies have dynamical masses and stellar population ages expected for the progenitors of massive, early-type galaxies in local clusters, potentially linking these populations.

Abstract
Very-high-energy (VHE; > 100 GeV) gamma-ray emission from the blazar RGB J2243+203 was discovered with the VERITAS Cherenkov telescope array, during the period between 2014 December 21 and 24. The VERITAS energy spectrum from this source can be fitted by a power law with a photon index of 4.6 ± 0.5, and a flux normalization at 0.15 TeV of

. The integrated Fermi-LAT flux from 1 to 100 GeV during the VERITAS detection is

, which is an order of magnitude larger than the four-year-averaged flux in the same energy range reported in the 3FGL catalog, (

). The detection with VERITAS triggered observations in the X-ray band with the Swift-XRT. However, due to scheduling constraints Swift-XRT observations were performed 67 hr after the VERITAS detection, rather than simultaneously with the VERITAS observations. The observed X-ray energy spectrum between 2 and 10 keV can be fitted with a power law with a spectral index of 2.7 ± 0.2, and the integrated photon flux in the same energy band is

. EBL-model-dependent upper limits of the blazar redshift have been derived. Depending on the EBL model used, the upper limit varies in the range from z

Participatory design of citizen science experiments
Authors: Senabre Enric , Ferran-Ferrer Núria , Perelló Josep 
Published: November 2017

This article describes and analyzes the collaborative design of a citizen science research project through cocreation. Three groups of secondary school students and a team of scientists conceived three experiments on human behavior and social capital in urban and public spaces. The study goal is to address how interdisciplinary work and attention to social concerns and needs, as well as the collective construction of research questions, can be integrated into scientific research. The 95 students participating in the project answered a survey to evaluate their perception about the dynamics and tools used in the cocreation process of each experiment, and the five scientists responded to a semistructured interview. The results from the survey and interviews demonstrate how citizen science can achieve a “cocreated” modality beyond the usual “contributory” paradigm, which usually only involves the public or amateurs in data collection stages. This type of more collaborative science was made possible by the adaptation of materials and facilitation mechanisms, as well as the promotion of key aspects in research such as trust, creativity and transparency. The results also point to the possibility of adopting similar codesign strategies in other contexts of scientific collaboration and collaborative knowledge generation

Tres grupos de estudiantes de centros de educación secundaria y un equipo de científicos idearon de forma participada tres experimentos sobre comportamiento humano y capital social en espacios públicos y urbanos. El objetivo del estudio es abordar cómo pueden integrarse en una investigación científica el trabajo interdisciplinar y la atención a preocupaciones y necesidades sociales, así como la construcción colectiva de preguntas de investigación. Los 95 estudiantes participantes en el proyecto respondieron una encuesta para evaluar su percepción sobre las dinámicas y herramientas utilizadas en el proceso de cocreación de cada experimento, y los cinco científicos respondieron a una entrevista semiestructurada. Los resultados de las encuestas y entrevistas demuestran cómo la ciencia ciudadana puede alcanzar una modalidad «cocreada» más allá del paradigma habitual «contributivo», el cual únicamente suele implicar al público o amateurs en la recopilación de datos. Esta modalidad de ciencia más colaborativa con la ciudadanía fue posible gracias a la adecuación de materiales y mecanismos de facilitación, así como al fomento de aspectos clave en una investigación como pueden ser la confianza, la creatividad y la transparencia. Los resultados apuntan también hacia la posibilidad de adoptar estrategias similares de codiseño en otros contextos de colaboración científica y generación colaborativa de conocimiento
Faire feu de tout bois
Authors: Gauthier Christophe 
Published: November 2017

Roland Topor n’a jamais souhaité être enfermé dans la seule profession de dessinateur, et l’une de ses principales caractéristiques est bien la manière dont il s’est approprié les industries culturelles de son temps, qu’il s’agisse du cinéma ou de la télévision, dans des genres symboliquement illégitimes (le dessin animé pas vraiment pour les enfants, la télévision pas tout à fait pour les adultes). Cette grande diversité l’a conduit à mettre en place des stratégies bien particulières. On en identifiera trois. La première concerne les réemplois multiples de ses dessins, dans des revues aux statuts eux-mêmes très divers. La deuxième intéresse le public, et le trouble intentionnel dans lequel La planète sauvage jette la critique de son temps, alors que l’on ne saurait considérer un film d’animation comme un objet qui ne soit pas destiné aux enfants. La troisième, enfin, vient perturber la place de l’auteur, tant les collaborations multiples auxquelles se livre Roland Topor semblent à contre-courant d’une représentation convenue d’un artiste unique détenant le contrôle sur son œuvre. Autant de manières de « désorienter » son travail, qui montrent combien l’utilisation des industries culturelles peut s’avérer féconde dans une démarche d’artiste qui a toujours cherché à s’affranchir des stéréotypes.
Dessiner à la télévision : Topor invité de Tac au Tac (1971-1972)
Authors: Tillier Bertrand 
Published: November 2017

En 1971-1972, Roland Topor fut à trois reprises l’invité de l’émission de Jean Frapat, Tac au Tac , diffusée depuis 1969 à la télévision française. Ce jeu inspiré du cadavre exquis surréaliste avait pour principe de rassembler, sur un même plateau du service de la recherche de l’ORTF, des dessinateurs de presse et de bande dessinée, afin de les confronter, sous l’œil des caméras, à des dispositifs dialogiques graphiques. L’article analyse les contraintes ludiques inventées par Frapat et les conditions de production de son émission, en regard de son ambition visant à constituer une encyclopédie télévisée du dessin contemporain. L’étude s’emploie également à interroger la participation de Topor à ce programme et à évaluer la place de son propre univers dans cette configuration expérimentale.
Topor et Kubin : le symbolisme en partage ?
Authors: Goldberg Itzhak 
Published: November 2017

L’article cherche à montrer les parallèles et les différences entre les univers symbolistes d’Alfred Kubin et de Roland Topor. Si l’essentiel de la recherche est consacré à Kubin, c’est que Topor, qui a connu cette œuvre à partir de 1962, ne cacha pas son admiration pour l’artiste autrichien. Les liens de Topor avec Kubin passent par l’héritage partagé d’une imagerie Mitteleuropa grinçante et hallucinée, mais aussi d’une pratique de l’écriture renvoyant à L’Autre côté . Toutefois, c’est probablement l’iconographie qui offre le terrain commun le plus important, car l’artiste français y reprend l’essentiel de la thématique symboliste de son aîné autrichien – et surtout celle convoquant la femme et la mort. Cependant, là où l’image de Kubin constitue un monde imaginaire dans lequel glisse le spectateur, chez Topor, la dérision et le regard critique obligent à la distanciation.
Topor et les jeux de l’art contemporain
Authors: Devaux Alexandre 
Published: November 2017

La multiplicité des médias, supports et techniques caractérise l’œuvre de Topor. Avec le dessin et l’écriture, un crayon et du papier, il montre l’étendue des possibilités qu’offrent les outils de création. Le « multiple », Topor le revendique comme subversion de l’« unique ». Le sens, les significations, la fonction des êtres et des objets ne doivent être réduits, selon lui, aux seuls diktats de la société de consommation. L’œuvre d’art est un produit de communication. Sur ce terrain, tous les jeux et toutes les complexités individuelles sont possibles pour ouvrir la création, le champ de découvertes de nouvelles formes et significations. Topor a mis cette dynamique en œuvres, c’est-à-dire en formes, en livres et en actes divers. Cette dimension multiple de l’œuvre de Topor contribue à le faire se rapprocher de certaines avant-gardes artistiques de son temps et plus spécifiquement des Nouveaux Réalistes ou de Fluxus.
Cutting Edge: c-Maf Is Required for Regulatory T Cells To Adopt RORγt+ and Follicular Phenotypes
Authors: Wheaton Joshua D. , Yeh Chen-Hao , Ciofani Maria 
Published: November 2017

Abstract
Regulatory T cells (Tregs) adopt specialized phenotypes defined by coexpression of lineage-defining transcription factors, such as RORγt, Bcl-6, or PPARγ, alongside Foxp3. These Treg subsets have unique tissue distributions and diverse roles in maintaining organismal homeostasis. However, despite extensive functional characterization, the factors driving Treg specialization are largely unknown. In this article, we show that c-Maf is a critical transcription factor regulating this process in mice, essential for generation of both RORγt+ Tregs and T follicular regulatory cells, but not for adipose-resident Tregs. c-Maf appears to function primarily in Treg specialization, because IL-10 production, expression of other effector molecules, and general immune homeostasis are not c-Maf dependent. As in other T cells, c-Maf is induced in Tregs by IL-6 and TGF-β, suggesting that a combination of inflammatory and tolerogenic signals promote c-Maf expression. Therefore, c-Maf is a novel regulator of Treg specialization, which may integrate disparate signals to facilitate environmental adaptation.
The Mod Two Cohomology of the Moduli Space of Rank Two Stable Bundles on a Surface and Skew Schur Polynomials
Authors: Scaduto Christopher W. , Stoffregen Matthew 
Published: November 2017

AbstractWe compute cup-product pairings in the integral cohomology ring of the moduli space of rank two stable bundles with odd determinant over a Riemann surface using methods of Zagier. The resulting formula is related to a generating function for certain skew Schur polynomials. As an application, we compute the nilpotency degree of a distinguished degree two generator in the mod two cohomology ring. We then give descriptions of the mod two cohomology rings in low genus, and describe the subrings invariant under the mapping-class group action.
Bounds on Multiple Self-avoiding Polygons
Authors: Hong Kyungpyo , Oh Seungsang 
Published: November 2017

AbstractA self-avoiding polygon is a lattice polygon consisting of a closed self-avoiding walk on a square lattice. Surprisingly little is known rigorously about the enumeration of self-avoiding polygons, although there are numerous conjectures that are believed to be true and strongly supported by numerical simulations. As an analogous problemto this study, we considermultiple self-avoiding polygons in a confined region as a model for multiple ring polymers in physics. We find rigorous lower and upper bounds for the number pm×n of distinct multiple self-avoiding polygons in the m × n rectangular grid on the square lattice. For m = 2, p2×n = 2n−1 − 1. And for integers m, n ≥ 3,
Shaping (Global) Leaders or Creating (Global) Citizens? Considering the Competing Purposes of Higher Education
Authors: Cole Rose 
Published: November 2017

Abstract
Focusing mainly on one particularly rich and illustrative case study—the University of Virginia—and grounded in a larger ethnographic study of higher education for citizenship, this research examines the frameworks of education for citizenship/global citizenship versus education for (global) leadership with empirical data from institutional policies and documents, courses and supplemented with observations and interviews with faculty and students. This paper makes two main claims. First, that the contemporary emphasis on leadership development within U.S. institutions of higher education is a symptom of and contributes to the perception of higher education as a private good instead of a public good. The second, related argument is that higher education for leadership has been conflated with higher education for citizenship.
The Misinformation Effect and the Type of Misinformation: Objects and the Temporal Structure of an Episode
Authors: Han Yuhwa 
Published: November 2017

Abstract
This study aimed to modify the stimulus set used to test the misinformation effect developed by Takarangi and her colleagues. The narratives and memory tests were modified to include items asking about specific objects in the story and about the temporal structure of the events. To examine whether the new material could produce the misinformation effect, the author had 72 participants watch a video, read a narrative with misinformation about objects in the video or the temporal sequence in the video, and then take a memory recognition test. This study showed that the misinformation effect could be produced by the temporal misinformation, suggesting that participants were misled by the misinformation regardless of the type of misinformation. As a result of using the modified narratives and the memory test, researchers could examine the effects of multiple types of misinformation.
Out of Thin Air: Configurability, Choreography, and the Air Guitar World Championships
Authors: McDaniel Byrd 
Published: November 2017

Abstract
In annual air guitar competitions, performers choreograph routines that simulate and exaggerate gestures needed to play “real” guitar. Before competitions, they edit and alter popular music to facilitate routines. Based on fieldwork at local and national competitions in the United States and the international competition in Finland, my research demonstrates connections between remix aesthetics offstage and choreographies onstage, where competitors configure, conjure, and consume popular music. Rather than viewing competitions as evidence of uninhibited interpretive agency of popular music consumers, I argue that power differentials emerge where identity, sensibility, physical skills, and acquired skills determine types and degrees of participation possible for practitioners.
Lokale politieke participatie: wie doet wat en wie wil wat?
Authors: Dekker Paul , den Ridder Josje 
Published: November 2017

Local political participation: who does something and who wants something?
This article investigates the state of affairs of local participation and participation wishes, and its backgrounds. The central question is if those who participate a lot are also those who wish to have more participation or not. It is not possible to simply summarize the developments in time in terms of ‘less and less’ participation and ‘more and more’ wishes. Since the seventies the turnout in municipal elections has fallen (against fluctuations without trend at the national elections) and collective actions for local goals have remained at the same level (against a fall in collective actions for supralocal goals). In 2016 also less people have appeared to participate non-electorally (19% local activists) than electorally (54% turnout in 2014). In addition the support for new opportunities for participation is larger than the actual use of existing opportunities. Political participants are almost as often as non-participants in favour of new opportunities for participation. In line with previous research the authors find several social and political attitudes in support of promoting more opportunities for participation. For participants as well as non-participants it applies that support for more opportunities is promoted by ‘positive’ characteristics (like interest in local politics, worries about the environment) as well as ‘negative’ ones (dissatisfaction with local democracy, disbelief in the responsiveness of councillors).
Slotbeschouwing: geen levende lokale democratie zonder scepsis
Authors: van der Meer Tom 
Published: November 2017

Final view: no living local democracy without scepticism
In a final view the other guest editor draws conclusions on local democracy based on the analyses of the Local Election Research presented in this special issue. The good news is that the basic attitude of the Dutch people about their local democracy, their local institutions and their local government is quite positive. A picture of trust and satisfaction arises from the data that are available. However, the picture is much less positive if we look at the local democracy from the perspective of the monitoring citizen. The outcomes of municipal elections are largely dictated by national party preferences, which is both harmful for the process of representation before and the control and accountability after the election of the municipal council. In addition, the level of political participation at the local level is rather low and the participants are not a balanced reflection of the population, even in new forms of participation that are especially designed to break the dominance of the permanent participation elite.

A indústria de automóveis no Brasil tem uma participação no PIB industrial de 25%, movimentando um número considerável de trabalhadores em uma cadeia que engloba fornecedores de matéria-prima, autopeças, oficinas mecânicas, distribuidores entre outras. Considerando que existe um crescimento médio da frota de automóveis no Brasil de 5% ao ano, identifica-se a necessidade de estabelecer serviços que garantam o pleno funcionamento dessa frota atendendo os critérios de disponibilidade exigidos por seus usuários. A proposta dessa pesquisa é definir um modelo de diagnóstico que possibilite identificar em quais dimensões devem ser considerados investimentos em inovação para melhorar o nível de competitividade das oficinas. A pesquisa avalia a aplicação do modelo do Característico de Inovação Setorial para determinar as dimensões de inovação prioritárias realizando um survey com uma amostra de 150 empresas onde identifica-se as dimensões que possibilitam elevar os níveis de competição das empresas desse setor.
