Published: April 2015

AbstractWe discuss multivalued weakly Picard operators on partial Hausdorff metric spaces. First, we obtain Kikkawa-Suzuki type fixed point theorems for a new type of generalized contractive conditions. Then, we prove data dependence of a fixed points set theorem. Finally, we present sufficient conditions for well-posedness of a fixed point problem. Our results generalize, complement and extend classical theorems in metric and partial metric spaces.

Authors: Dastgheib Zeinab A , Lithgow Brian , Blakley Brian , Moussavi Zahra 
Published: April 2015

Objective To describe the development of a new clinically applicable method for assessing vestibular function in humans with particular application in Meniere's disease. Study design Sophisticated signal-processing techniques were applied to data from human subject undergoing tilts stimulating the otolith organs and semicircular canals. The most sensitive representatives of vestibular function were extracted as “features”. Methods After careful consideration of expected response features, Electrovestibulography, a modified electrocochleography, recordings were performed on fourteen Meniere's patients and sixteen healthy controls undergoing controlled tilts. The data were subjected to multiple signal processing techniques to determine which “features” were most predictive of vestibular responses. Results Linear discriminant analysis and fractal dimension may allow data from a single tilt to be used to adequately characterize the vestibular system. Conclusion Objective, physiologic assessment of vestibular function may become realistic with application of modern signal processing techniques.
Characterization of a fracture zone using seismic attributes at the In Salah CO2 storage project
Authors: Zhang Rui , Vasco Donald , Daley Thomas M. , Harbert William 
Published: April 2015

The In Salah carbon dioxide storage project in Algeria has injected more than 3 million tons of carbon dioxide into a water-filled tight-sand formation. During injection, interferometric synthetic aperture radar (InSAR) reveals a double-lobed pattern of up to a 20-mm surface uplift above the horizontal leg of an injection well. Interpretation of 3D seismic data reveals the presence of a subtle linear push-down feature located along the InSAR determined surface depression between the two lobes, which we interpreted to have to be caused by anomalously lower velocity from the fracture zone and the presence of [Formula: see text] displacing brine in this feature. To enhance the seismic interpretation, we calculated many poststack seismic attributes, including positive and negative curvatures as well as ant track, from the 3D seismic data. The maximum positive curvature attributes and ant track found the clearest linear features, with two parallel trends, which agreed well with the ant-track volume and the InSAR observations of the depression zone. The seismic attributes provided a plausible characterization of the fracture zone extent, including height, width, and length (80, 350, and 3500 m, respectively), providing important information for further study of fracture behavior due to the [Formula: see text] injection at In Salah. We interpreted the pattern of depression between two surface-deformation lobes as caused by the opening of a subvertical fracture or damage zone at depth above the injection interval, which allowed injected [Formula: see text] to migrate upward. Our analysis corroborated previous interpretation of surface uplift as due to the injection of [Formula: see text] in this well.

well-being

Published: April 2015

BackgroundThe relationship between well-being and mental ill health is complex;
people may experience very low levels of well-being even in the absence
of overt mental health problems.AimsThis study tested the hypothesis that anxiety, depression and well-being
have different causal determinants and psychological mediating
mechanisms.MethodThe influence of causal and mediating factors on anxiety, depression and
well-being were investigated in a cross-sectional online questionnaire
survey hosted on a UK national broadcasting website.ResultsMultivariate conditional independence analysis of data from 27 397
participants revealed different association pathways for the two
constructs. Anxiety and depression were associated with negative life
events mediated by rumination; low levels of subjective well-being were
associated with material deprivation and social isolation, mediated by
adaptive coping style.ConclusionsOur findings support the ‘two continua’ model of the relationship between
psychological well-being and mental health problems, with implications
for both treatment and prevention.
Customer Recognition in Experience vs. Inspection Good Markets
Authors: Jing Bing 
Published: April 2015

We study the effects of customer recognition and behavior-based price discrimination (BPD) in a two-period experience good duopoly with a discrete value distribution, and we investigate the role of consumers’ ex ante valuation uncertainty in dynamic price competition through comparison with an inspection good duopoly. Several results are reached. First, the firms may reward repeat purchase when the probability of a high value is relatively low and when the high–low value difference is large; otherwise, they may engage in poaching. Second, BPD frequently increases each firm’s total profits, even in the poaching equilibrium. These results contrast with the inspection good duopoly, and the driver is that consumers’ period 2 product preference depends on their realized values in period 1. Third, consumers’ ex ante valuation uncertainty may increase or decrease firm profits without BPD, and it weakly increases firm profits with BPD, relative to the inspection good duopoly. This paper was accepted by J. Miguel Villas-Boas, marketing.
Optimal Coordination Mechanisms for Unrelated Machine Scheduling

Published: April 2015

We investigate the influence of different algorithmic choices on the approximation ratio in selfish scheduling. Our goal is to design local policies that minimize the inefficiency of resulting equilibria. In particular, we design optimal coordination mechanisms for unrelated machine scheduling, and improve the known approximation ratio from Θ(m) to Θ(log m), where m is the number of machines. A local policy for each machine orders the set of jobs assigned to it only based on parameters of those jobs. A strongly local policy only uses the processing time of jobs on the same machine. We prove that the approximation ratio of any set of strongly local ordering policies in equilibria is at least Ω(m). In particular, it implies that the approximation ratio of a greedy shortest-first algorithm for machine scheduling is at least Ω(m). This closes the gap between the known lower and upper bounds for this problem and answers an open question raised by Ibarra and Kim (1977) [Ibarra OH, Kim CE (1977) Heuristic algorithms for scheduling independent tasks on nonidentical processors. J. ACM 24(2):280–289.], and Davis and Jaffe (1981) [Davis E, Jaffe JM (1981) Algorithms for scheduling tasks on unrelated processors. J. ACM 28(4):721–736.]. We then design a local ordering policy with the approximation ratio of Θ(log m) in equilibria, and prove that this policy is optimal among all local ordering policies. This policy orders the jobs in the nondecreasing order of their inefficiency, i.e., the ratio between the processing time on that machine over the minimum processing time. Finally, we show that best responses of players for the inefficiency-based policy may not converge to a pure Nash equilibrium, and present a Θ(log2 m) policy for which we can prove fast convergence of best responses to pure Nash equilibria.
The new communicative ethos of the political debate talk show in Danish multi-platform public service television
Authors: Bruun Hanne 
Published: April 2015

Abstract
This article presents an analysis of the attempt to revitalize the genreviewer relationship in the political debate talk show in multi-platform public service television in Denmark. Based on the generic development since the 1990s, and main findings from a comprehensive case study of the interaction between the live broadcast and the Facebook profile of the show The Debate, the article argues that the communicative ethos has changed profoundly. Populism is no longer adequate to understand the entertaining qualities produced. Finally, the article discusses the emerging conceptualization of the audience at work in the production culture and the creative challenges it entails.

Abstract: This research is based on the reasoning that transformation of IAIN to UIN can not release the expectation to do the integration of science and shake off dichotomy both Islam and science. The dichotomous of Islam and science appear in cosequence of the differences at the level of ontological, epistemological and axiological in religious sciences (Islam) and general sciences. In response to preliminary research and findings with respect to science integration in UIN, researchers assume to do comprehensive research to find out at analyzing the implementation of the integration of science in UIN throughout Indonesia, especially in the context of curriculum design and the learning process.

Published: April 2015

BackgroundMost inspiratory muscle training (IMT) interventions in patients with chronic obstructive pulmonary disease (COPD) have been implemented as fully supervised daily training for 30 minutes with controlled training loads using mechanical threshold loading (MTL) devices. Recently, an electronic tapered flow resistive loading (TFRL) device was introduced that has a different loading profile and stores training data during IMT sessions.ObjectiveThe aim of this study was to compare the efficacy of a brief, largely unsupervised IMT protocol conducted using either traditional MTL or TFRL on inspiratory muscle function in patients with COPD.DesignTwenty patients with inspiratory muscle weakness who were clinically stable and participating in a pulmonary rehabilitation program were randomly allocated to perform 8 weeks of either MTL IMT or TFRL IMT.MethodsParticipants performed 2 daily home-based IMT sessions of 30 breaths (3–5 minutes per session) at the highest tolerable intensity, supported by twice-weekly supervised sessions. Adherence, progression of training intensity, increases in maximal inspiratory mouth pressure (Pimax), and endurance capacity of inspiratory muscles (Tlim) were evaluated.ResultsMore than 90% of IMT sessions were completed in both groups. The TFRL group tolerated higher loads during the final 3 weeks of the IMT program, with similar effort scores on the 10-Item Borg Category Ratio (CR-10) Scale, and achieved larger improvements in Pimax and Tlim than the MTL group.LimitationsA limitation of the study was the absence of a study arm involving a sham IMT intervention.ConclusionsThe short and largely home-based IMT protocol significantly improved inspiratory muscle function in both groups and is an alternative to traditional IMT protocols in this population. Participants in the TFRL group tolerated higher training loads and achieved larger improvements in inspiratory muscle function than those in the MTL group.
Exosomal sorting of the viral oncoprotein LMP1 is restrained by TRAF2 association at signalling endosomes

Published: April 2015

The Epstein–Barr virus (EBV)‐encoded oncoprotein latent membrane protein 1 (LMP1) constitutively activates nuclear factor κB (NFκB) from intracellular membranes to promote cell growth and survival. LMP1 associates with CD63 in intracellular membranes and is released via exosomes. Whether tumour necrosis factor (TNF) receptor‐associated factors (TRAFs) mediate LMP1 NFκB signalling from endosomes and modulate exosomal sorting is unknown. In this article, we show that LMP1–TRAF2 signalling complexes accumulate at endosomes in a palmitoylation‐dependent manner, thereby driving LMP1‐dependent oncogenicity. Palmitoylation is a reversible post‐translational modification and is considered to function as a membrane anchor for proteins. Mutagenesis studies showed that LMP1–TRAF2 trafficking to endosomes is dependent on one single cysteine residue (C78), a known palmitoylation site of LMP1. Notably, growth assays in soft agar revealed that oncogenic properties of the palmitoylation‐deficient LMP1 mutant C78A were diminished compared to wild‐type LMP1. Since LMP1 recruitment of TRAF2 and downstream NFκB signalling were not affected by a disturbance in palmitoylation, the specific localization of LMP1 at endosomal membranes appears crucial for its transforming potential. The importance of palmitoylation for trafficking to and signalling from endosomal membranes was not restricted to LMP1, as similar observations were made for the cellular oncoproteins Src and Fyn. Despite abundant LMP1–TRAF2 association at endosomal membranes TRAF2 could not be detected in exosomes by Western blotting or proteomics. Interestingly, point mutations that prevented TRAF binding strongly promoted the sorting and release of LMP1 via exosomes. These observations reveal that LMP1–TRAF2 complexes at endosomes support oncogenic NFκB activation and suggest that LMP1 dissociates from the activated signalling complexes upon sorting into intraluminal vesicles. We propose that “signalling endosomes” in EBV‐infected tumour cells can fuse with the plasma membrane, explaining LMP1 release via exosomes.
A variation on chloroplast development: The bizonoplast and photosynthetic efficiency in the deep‐shade plant Selaginella erythropus

• Premise of the study: Chloroplast development and structure are highly conserved in vascular plants, but the bizonoplast of Selaginella is a notable exception. In the shade plant S. erythropus, each dorsal epidermal cell contains one bizonoplast, while other cells have normal chloroplasts. Our quest was to (1) determine the origin of bizonoplasts, (2) explore developmental plasticity, and (3) correlate developmental changes with photosynthetic activity to provide insights unavailable in other green plants with more constrained development.• Methods: Bizonoplast development was studied in juvenile prostrate and older erect shoots of S. erythropus. Plastid plasticity was studied in plants cultivated under different light conditions. Chlorophyll fluorescence was measured and correlated with photosynthetic activity.• Key results: The bizonoplast originates from a proplastid, forming a distinctive upper zone rapidly after exposure to low light. In the prostrate shoots, the proplastid develops through early stages only. When the shoot becomes erect, the proplastid soon develops into a mature bizonoplast. Erect shoots have significantly higher photosynthetic efficiency than prostrate shoots. No bizonoplasts were found in the plants growing in high light, where 2–4 spheroidal chloroplasts formed, or with light from below.• Conclusions: The upper zone develops above a normal‐looking chloroplast structure to produce a bizonoplast. Bizonoplast developmental plasticity suggests that regular lamellar structure and monoplastidy are adaptations to deep shade environments. Such novel variation in S. erythropus is in stark contrast to known plastid development in other vascular plants, possibly reflecting retention of developmental flexibility in the basal clade, Lycophyta, to which it belongs.
De l’événement dans l’espace thérapeutique de personnes ayant été torturées
Authors: Montagut Muriel 
Published: April 2015

Les sujets ayant été torturés tentent de se défaire de l’emprise d’un système dans l’espace thérapeutique. Leur lutte, toujours singulière, se fait entendre par des temps de rupture avec les logiques acquises durant les sévices. Ces ruptures constituent le ressaisissement de l’être et marquent sa volonté de s’inscrire dans de nouvelles possibilités d’être. Ces temps, en ponctuant le dégagement du sujet de l’emprise de la torture, font événement (c’est-à-dire créent une rupture dans la continuité d’être du sujet) et nécessiteront un travail d’élaboration pour que cette entreprise de dégagement soit conscientisée par le sujet et puisse se consolider. Cet article revient sur trois temps fondamentaux capables de faire événement dans ce type de thérapie : le temps inaugural de la rencontre avec le thérapeute, le temps de la réémergence du sujet par l’irruption de métaphores poétiques et le temps de la reconnaissance sociale par l’obtention du statut de réfugié politique.
Chercher l’événement pour se sentir vivant
Authors: Lévy André , Giust-Desprairies Florence 
Published: April 2015

Boris Cyrulnik, au cours d’un entretien, veut voir l’événement comme constitutif de la vie : sans événement, pas de vie. C’est ainsi que, se référant à son expérience de neuropsychiatre et d’éthologue, il soutient que l’on va le chercher. L’événement participe ainsi à la constitution de la sensation de vivre chez les animaux, chez les bébés préverbaux comme chez tout être humain. Sa représentation, largement tributaire de la qualité des rapports affectifs avec les proches, se traduit matériellement par des modifications de la structure du cerveau. Deux temps sont à distinguer : celui de la nécessité d’une sensation d’être vivant et le temps de la représentation de ce qui nous est arrivé. Le neurologue développe ainsi sa pensée en prenant différents exemples qui lui permettent de rendre compte des processus de restauration de soi, en soulignant notamment l’importance de la dimension culturelle.
