Background: Recently, endoscopic ultrasound-guided gall bladder drainage (EUS-GBD) has been reported using a self-expandable metallic stent. To prevent stent migration and food flowing into the common bile duct through the cystic duct, we perform a novel EUS-guided cholecystoduodenostomy. The aim of our study was to evaluate the safety and feasibility of EUS-guided cholecystoduodenostomy with an anti-stent migration and anti-food impaction system. Methods: A total of 16 consecutive patients who underwent EUS-guided cholecystoduodenostomy for acute cholecystitis were included in this study. Results: Technical and clinical success was obtained in all patients. The median procedure time was 26.9 min (range 19–42 min). Median follow-up time was 181.5 days (range 18–604 days), and in this time, recurrence of acute cholecystitis was not seen in all patients. Adverse events such as stent migration and cholangitis were not seen in any patients, although pneumoperitoneum was seen in one patient. Conclusion: Our technique may be favorable and effective for the prevention of adverse events on EUS-GBD.
A 6-week, double-blind, placebo- and haloperidol-controlled, phase II study of lurasidone in patients with acute schizophrenia
Authors: Potkin Steven G. , Kimura Tatsuya , Guarino John 
Published: October 2015

Objective: The objective of this study was to evaluate the short-term efficacy and safety of the atypical antipsychotic agent lurasidone in the treatment of schizophrenia. Methods: In this phase II, randomized, double-blind, placebo-controlled study, hospitalized adult patients diagnosed with schizophrenia and experiencing an acute exacerbation of psychotic symptoms were randomly assigned to 6 weeks of fixed-dose lurasidone 20 mg/day ( n = 71), lurasidone 40 mg/day ( n = 67), lurasidone 80 mg/day ( n = 71), haloperidol 10 mg/day ( n = 72, included to test for assay sensitivity), or placebo ( n = 72). Efficacy was assessed using the brief psychiatric rating scale, positive and negative syndrome scale, and clinical global impression-severity. Safety assessments included incidence of adverse events and clinical laboratory measures. Results: Numerical improvement was observed from baseline to week 6 (last observation carried forward) on all efficacy measures in all treatment groups; however, no statistically significant differences were noted between any lurasidone group and placebo, or between haloperidol and placebo. The most common adverse events in lurasidone-treated patients, with an incidence of at least 10% (dose groups combined) and greater than placebo, were sedation (15.3%), dyspepsia (13.4%), nausea (13.4%), akathisia (12.4%), and vomiting (10.5%); for haloperidol, the most common adverse events (incidence ⩾ 10% and greater than placebo) were extrapyramidal disorder (20.8%), sedation (19.4%), akathisia (19.4%), dystonia (15.3%), insomnia (13.9%), and somnolence (12.5%). Lurasidone was associated with minimal changes in weight, metabolic parameters, and prolactin levels. Conclusions: None of the lurasidone groups separated from placebo in this clinical study of patients with acute schizophrenia. In addition, haloperidol, which was included for assay sensitivity, did not separate from placebo, resulting in a failed study. Possible reasons for the lack of assay sensitivity in this study include the use of multiple active treatment arms and the relatively large placebo response. Consistent with other studies, lurasidone was generally safe and well tolerated, with minimal effects on weight or metabolic parameters.

Published: October 2015

Abstract
The ability to control cell function is one of the challenges for cell-based therapy in regenerative medicine. In this study, we describe a novel method to fabricate cell–hydroxyapatite (HAp) nanocrystal composites to modulate cellular microenvironment. By preparation of layer-by-layer nanometer-sized extracellular matrix films onto cell surfaces, HAp nanocrystals were fabricated onto cell surfaces without cytotoxicity. This technology can modulate cellular functions such as adhesion, growth, and differentiation.

The Impact of Modeling on Robust Inventory Management Under Demand Uncertainty
Authors: Solyalı Oğuz , Cordeau Jean-François , Laporte Gilbert 
Published: October 2015

This study considers a basic inventory management problem with nonzero fixed order costs under interval demand uncertainty. The existing robust formulations obtained by applying well-known robust optimization methodologies become computationally intractable for large problem instances due to the presence of binary variables. This study resolves this intractability issue by proposing a new robust formulation that is shown to be solvable in polynomial time when the initial inventory is zero or negative. Because of the computational efficiency of the new robust formulation, it is implemented on a folding-horizon basis, leading to a new heuristic for the problem. The computational results reveal that the new heuristic is not only superior to the other formulations regarding the computing time needed, but also outperforms the existing robust formulations in terms of the actual cost savings on the larger instances. They also show that the actual cost savings yielded by the new heuristic are close to a lower bound on the optimal expected cost.

Service Competition and Product Quality in the U.S. Automobile Industry
Authors: Guajardo Jose A. , Cohen Morris A. , Netessine Serguei 
Published: October 2015

We study the impact of service attributes (warranty length, after-sales service quality) on consumer demand in the U.S. automobile industry, examining the presence of complementarities/substitution between service attributes and product quality. Our results estimate a median willingness to pay for one year of a warranty of approximately $850, which is equivalent to 3.1% of the median vehicle price in our sample. We find that, for a car with median characteristics, the effect on consumer utility of a 1% price decrease is equivalent, all else being equal, to increasing product quality by 2.2%, and is in turn equivalent to increasing the warranty length by 8%. Our results also indicate that service attributes play a compensatory role with respect to product quality; i.e., the impact of warranty length and service quality on demand increases when product quality decreases. Conversely, both service metrics are complementary with respect to demand; i.e., the better the service quality, the higher the marginal effect of longer warranties. Our results thus imply that, in our period of analysis, warranties played a more important role for American firms than for foreign firms, consistent with the fact that American manufacturers exhibited lower product quality and higher service quality than non-American firms.

Contesting agendas of participation in the arts
Authors: Price Jonathan 
Published: October 2015

Abstract
Forms of participatory practice have become ever more widely employed across the arts in recent years, operating across various institutional settings and social contexts. It is misleading, however, to assume that a single agenda binds these developments or that they serve the same social values and interests. Veils of common terminology can conceal important differences of political intent and ethical integrity. Conceptions of art, artists, culture and community vary widely, while terms such as participation, engagement and co-creation are rarely well defined. This article draws on current research into UK cultural and artistic leadership, as well as established theories of participation and action, to explore the complex power relations that underpin participatory discourse. It critiques policies and practices that claim ‘participation’ as an automatic methodological virtue, questioning the positive connotations of participatory language, particularly in relation to shaping assumptions of shared interest. It argues that there is a need for improved critical selfawareness on the part of artists involved in participatory projects and processes, discussing possible frameworks for analysis of the relevant power relationships.
Theatre for social change: Collective Encounters on rediscovering the radical
Authors: Thornton Sarah 
Published: October 2015

Abstract
This article will describe Collective Encounters’ participatory practice and situate it within the field of Theatre for Social Change (TFSC). It will argue that in the current political climate TFSC can be a useful tool of opposition. The article will chart the company’s radicalization and call for a repoliticization of the participatory arts sector. It will explore how theatre can contribute to social justice in the context of austerity, how it can challenge the ubiquitous neo-liberal narrative, and what kinds of participatory arts practices might aid the global movement for radical change.
Collective Encounters is a professional arts organization specializing in TFSC. The company is based in north Liverpool, an area of extreme disadvantage, ranked among the top ten in England’s Indices of Multiple Deprivation (DCMS 2011). It works with diverse marginalized communities both here and in the wider North West: many participants are casualties of the prevailing system and feel the direct impact of benefit cuts and the shrinking of the state. Collective Encounters is a small charity employing seven staff members and additional freelance artists as required. It is governed by a board of directors and has a formal legal company structure. The company provides all its work free at the point of use, and thus is dependent on public funding as well as on grants from trusts and foundations. Since 2004, Collective Encounters has maintained three strands to its work: a participatory programme, a professional theatre programme and a research lab. The company is driven by a research imperative to explore ways in which theatre can contribute to the world-wide ‘multitude of opposition’1, working towards greater social justice and against global corporate capitalism’ (Thornton 2015: 2). Over the past five years it has shifted from a liberal to a radical change agenda, and has conducted academic, practical and sectoral research in order to understand and define its field. It has thus identified TFSC as a discernable set of practices by drawing out five key characteristics: intentionality, community, hyphenation, conscientization and aesthetics. While individually they are not unique to TFSC, taken together they frame the field; they are the driving forces behind Collective Encounters thinking and provoke the ethical dilemmas with which the company grapples. They provide an interesting lens through which to view participatory arts practice within the current social and political climate.
Participatory film-making for social change: Dilemmas in balancing participatory and artistic qualities
Authors: Goris Margriet , Witteveen Loes , Lie Rico 
Published: October 2015

Abstract
This study contributes to the field of films for social change by exploring the production process of participatory film-making for social change, whereby explicit claims of community empowerment, participation and social change are the very justification of the production. To do so, it investigates the definitions and production processes of community art, participatory video and mediated participation. Using ‘practice as research’ as a key method of enquiry, we examine three film practices to explore aspects of professionalism. The objective of this examination is to elucidate the process of community member participation in collaboration with film-makers, facilitators and action researchers. People participate in film production processes by contributing to the script, acting, location scouting or any other activity at any stage of the film production. In examining this collaborative process, we focus on dilemmas encountered in relation to integrating participatory qualities and artistic qualities in a work of overall interdisciplinary and professional quality. The material used for the enquiry consists of participatory observations, scripts, films, course materials, audience observations, evaluation forms and in-depth interviews collected over the years in different projects. The analysis of the material indicates that the film-makers deal with dilemmas regarding the balance of the film’s participatory and artistic qualities and the production process. The expectations of the film-making community regarding the process, the resulting film and the related audience influence the balance between the participatory quality of the process and the artistic quality of the film. Finding a balance between participatory quality and artistic quality is a challenge, and in practice the stakeholders involved experience tensions in a continuous process of negotiation. This article demonstrates the tensions and illustrates the continuous process of negotiation between the (roles of) film-makers, facilitators, action researchers and community members.
Three cases of engaged research. The participation of the researcher in arts participation projects
Authors: Hansen Louise Ejgod 
Published: October 2015

Abstract
The article is a case study of three different applied research projects analysing and discussing the relationship between practice and research. The three projects are all arts projects occupied with participation in different forms: ‘Theatre Talk’ is an audience development project conducted at professional theatres focusing on new audiences’ experience of performances. ‘Art on the Fringe’ is a project in which seven theatres cooperating on the development of local festive weeks with a strong participatory element within a theatrical framing. ‘Stepping Stones’ is a project aiming at developing new frameworks for the way in which children and youngsters engage in creative practices emphasizing collective co-creation. Theoretically, the article is based on the concept of engaged scholarship, practice as research and types of partnership all of which contribute to the analysis of the relationship, purpose, and outcomes of the cooperation between practice and research.
On the index of symmetric spaces
Authors: Berndt Jürgen , Olmos Carlos 
Published: October 2015

Abstract
Let M be an irreducible Riemannian symmetric space. The index of M is the minimal codimension of a (nontrivial) totally geodesic submanifold of M. We prove that the index is bounded from below by the rank of the symmetric space. We also classify the irreducible Riemannian symmetric spaces whose index is less than or equal to 3.
Singular values and evenness symmetry in random matrix theory
Authors: Bornemann Folkmar , Forrester Peter J. 
Published: October 2015

Abstract
Complex Hermitian random matrices with a unitary symmetry can be distinguished by a weight function. When this is even, it is a known result that the distribution of the singular values can be decomposed as the superposition of two independent eigenvalue sequences distributed according to particular matrix ensembles with chiral unitary symmetry. We give decompositions of the distribution of singular values, and the decimation of the singular values – whereby only even, or odd, labels are observed – for real symmetric random matrices with an orthogonal symmetry, and even weight. This requires further specifying the functional form of the weight to one of three types – Gauss, symmetric Jacobi or Cauchy. Inter-relations between gap probabilities with orthogonal and unitary symmetry follow as a corollary. The Gauss case has appeared in a recent work of Bornemann and La Croix. The Cauchy case, when appropriately specialised and upon stereographic projection, gives decompositions for the analogue of the singular values for the circular unitary and circular orthogonal ensembles.
Satire as uncertain territory: Uncertainty expression in discussion about political satire, opinion, and news
Authors: Landreville Kristen D. 
Published: October 2015

AbstractThis study integrates satire literature and uncertainty-based theories in order to introduce more theoretical organization into the political communication and discussion literature. In doing so, the main goals of this study are (1) to bring conceptual organization to various types of political messages (i.e., satire and news), (2) to show how and why satire, in particular, is linked with uncertainty, and (3) to examine the extent to which satire and news can arouse uncertainty and encourage discussion of uncertainty in political conversations. Four types of political media messages (traditional news, opinion news, juvenalian satire, and horatian satire) are used in a computer-mediated discussion experiment to answer the study’s hypotheses. Results show that uncertainty differed across political messages (i.e., satire aroused more uncertainty) and uncertainty was expressed in discussion.
Automatic Data Clustering Using Parameter Adaptive Harmony Search Algorithm and Its Application to Image Segmentation
Authors: Kumar Vijay , Chhabra Jitender Kumar , Kumar Dinesh 
Published: October 2015

AbstractIn this paper, the problem of automatic data clustering is treated as the searching of optimal number of clusters so that the obtained partitions should be optimized. The automatic data clustering technique utilizes a recently developed parameter adaptive harmony search (PAHS) as an underlying optimization strategy. It uses real-coded variable length harmony vector, which is able to detect the number of clusters automatically. The newly developed concepts regarding “threshold setting” and “cutoff” are used to refine the optimization strategy. The assignment of data points to different cluster centers is done based on the newly developed weighted Euclidean distance instead of Euclidean distance. The developed approach is able to detect any type of cluster irrespective of their geometric shape. It is compared with four well-established clustering techniques. It is further applied for automatic segmentation of grayscale and color images, and its performance is compared with other existing techniques. For real-life datasets, statistical analysis is done. The technique shows its effectiveness and the usefulness.
Development of 77Ge/77As parent-daughter system for periodic removal of 77As for environmental sanitation and biochemical purposes
Authors: Oláh Zita , Szűcs Zoltán , Varga Zoltán , Dóczi Rita 
Published: October 2015

Abstract
A simple method was developed for the separation of radioactive 77As from neutron irradiated natural GeO2 samples
for environmental and biochemical studies. The method is based on the volatility of GeCl4. The GeCl4 was
co-evaporated from the reaction mixture with an azeotropic mixture of HCl and water, and immediately condensed into a separate finger
part of the special glass apparatus which was cooled by liquid nitrogen.
By inverting the room temperature and the deep frozen parts of the glass equipment after three half-lives of the 77Ge the
separation process can be repetitive, getting a special type of 77Ge/77As parent-daughter system. The
radionuclidic purity of the remaining As fraction was found to be 99.95%. Its yield, however, drastically decreased in the
second and subsequent separations.
