Treatment of hemicrania continua with radiofrequency ablation and long-term follow-up
Authors: Beams Jennifer L , Kline Matthew T , Rozen Todd D 
Published: February 2015

Objective The objective of this research is to describe novel procedural treatments for hemicrania continua that allow patients to remain off indomethacin. Methods Case reports are presented. Results We describe four distinct patients with indomethacin-responsive hemicrania continua who were unable to discontinue the use of indomethacin without headache recurrence. No other medications were effective for their syndrome. Secondary causes of headache were ruled out in each case. Each patient underwent diagnostic blockade of either the atlanto-axial joint, C2 dorsal root ganglion or sphenopalantine ganglion depending on their clinical examination and presence of cranial autonomic symptoms. A positive response led to a radiofrequency ablation of the C2 ventral ramus, C2 dorsal root ganglion or sphenopalantine ganglion, which provided headache relief in all case patients as complete as indomethacin. Long-term follow-up of these patients has shown that all have remained essentially headache free without the need for indomethacin. One patient has needed repeat radiofrequency procedures with consistent response. Conclusion Hemicrania continua is defined by its sensitivity to indomethacin but very few patients are able to discontinue the medication without headache recurrence. As the risks of chronic indomethacin use are substantial, alternative treatments are necessary to protect patient health. We are now able to suggest several radiofrequency ablation procedures as effective as indomethacin with long-term follow-up.

Published: February 2015

Gastrointestinal bleeding is a leading cause of morbidity and mortality in the United States. The management of gastrointestinal bleeding is often challenging, depending on its location and severity. To date, widely accepted hemostatic treatment options include injection of epinephrine and tissue adhesives such as cyanoacrylate, ablative therapy with contact modalities such as thermal coagulation with heater probe and bipolar hemostatic forceps, noncontact modalities such as photodynamic therapy and argon plasma coagulation, and mechanical hemostasis with band ligation, endoscopic hemoclips, and over-the-scope clips. These approaches, albeit effective in achieving hemostasis, are associated with a 5–10% rebleeding risk. New simple, effective, universal, and safe methods are needed to address some of the challenges posed by the current endoscopic hemostatic techniques. The use of a novel hemostatic powder spray appears to be effective and safe in controlling upper and lower gastrointestinal bleeding. Although initial reports of hemostatic powder spray as an innovative approach to manage gastrointestinal bleeding are promising, further studies are needed to support and confirm its efficacy and safety. The aim of this study was to evaluate the technical feasibility, clinical efficacy, and safety of hemostatic powder spray (Hemospray, Cook Medical, Winston-Salem, North Carolina, USA) as a new method for managing gastrointestinal bleeding. In this review article, we performed an extensive literature search summarizing case reports and case series of Hemospray for the management of gastrointestinal bleeding. Indications, features, technique, deployment, success rate, complications, and limitations are discussed. The combined technical and clinical success rate of Hemospray was 88.5% (207/234) among the human subjects and 81.8% (9/11) among the porcine models studied. Rebleeding occurred within 72 hours post-treatment in 38 patients (38/234; 16.2%) and in three porcine models (3/11; 27.3%). No procedure-related adverse events were associated with the use of Hemospray. Hemospray appears to be a safe and effective approach in the management of gastrointestinal bleeding.

Published: February 2015

Abstract
We have obtained the surface-enhanced Raman scattering substrate by depositing silver nanoparticles on the surface of the inverted pyramidal nanovoid in order to improve the enhance effects. Experimental results showed that the combined substrate exhibited greater enhancement than the nanovoid substrate or nanoparticles. In order to test the SERS activity of the combined substrates, Rh6G and ricin toxin were used as Raman probes. Finite element method was employed to simulate electric field and induced charge distribution of the substrates, which have been used to explore the interaction between nanoparticles and nanovoid as well as mechanism of the great enhancement.
Long-term follow-up of herpetic non-necrotizing retinopathy with occlusive retinal vasculitis and neovascularization
Authors: Albert Kim , Masset Maureen , Bonnet Sabine , Willermain François , Caspers Laure 
Published: February 2015

Abstract

Background
Herpetic necrotizing retinitis is a well-recognized entity. A few cases of herpetic non-necrotizing retinitis were previously reported.

Findings
We retrospectively report two cases of herpetic non-necrotizing retinopathy with a long follow-up. A 19-year-old woman presented with a bilateral diffuse occlusive retinal vasculitis, peripheral neovascularization, and no signs of retinal necrosis. Long-lasting immunosuppressive treatment failed to control the vasculitis until herpes simplex virus type 1 (HSV1) was demonstrated by polymerase chain reaction (PCR) in the aqueous. Acyclovir was then added and immunosuppressive tapered and eventually stopped resulting in a resolution of vasculitis. Only two relapses occurred during the next 6 years and responded rapidly to oral acyclovir.
An 11-year-old boy presented with unilateral scar of stromal keratitis, severe vitritis, and optic disc neovascularization, followed 6 weeks later by peripheral occlusive retinal vasculitis. Therapeutic and diagnostic vitrectomy was performed, and PCR was found to be positive for varicella zoster virus (VZV) in a vitreous specimen. The inflammation responded to oral acyclovir therapy. Recurrence of anterior uveitis with iris depigmentation occurred 4 months after treatment was arrested. After 4 years, he presented again with a recurrence of anterior inflammation and cystoid macular edema (CME). No sign of inflammation was seen for the next 10 years.

Conclusions
These rare cases support the possible role of herpes viruses (HSV or VZV) in occlusive vasculitis without retinal necrosis. PCR was useful to raise the diagnosis and to adapt the treatment. A good response was obtained on oral antiviral therapy.
Activation and active labour market policies in OECD countries: stylised facts and evidence on their effectiveness
Authors: Martin John P 
Published: February 2015

AbstractActivation policies aimed at getting working-age people off benefits and into work have become a buzzword in labour market policies. Yet they are defined and implemented differently across OECD countries, and their success rates vary too. The Great Recession has posed a severe stress test for these policies, with some commentators arguing that they are at best “fair weather” policies. This paper sheds light on these issues mainly via the lens of recent OECD research. It presents the stylised facts on how OECD countries have responded to the Great Recession in terms of ramping up their spending on active labour market policies (ALMPs), a key component in any activation strategy. It then reviews the macroeconomic evidence on the impact of ALMPs on employment and unemployment rates. This is followed by a review of the key lessons from recent OECD country reviews of activation policies. It concludes with a discussion of crucial unanswered questions about activation.JEL codes:J01, J08, J68
Effect of SiO2 nanoparticle doping on electro-optical properties of polymer dispersed liquid crystal lens for smart electronic glasses
Authors: Kim Eunju , Liu Yang , Hong Sung-Jei , Han Jeong In 
Published: February 2015

Abstract
In this paper, SiO2 nanoparticle doped polymer dispersed liquid crystal (PDLC) lenses were made from a mixture of prepolymer, E7 liquid crystal and SiO2 nanoparticles by the polymerization induced phase separation (PIPS) process for smart electronic glasses with auto-shading and auto-focusing functions. Electro-optical properties of doped and undoped samples including transmittance, driving voltage, contrast ratio and slope of the linear region of the transmittance-voltage were measured, compared and analyzed. Driving voltage of SiO2 nanoparticle doped PDLC lenses moderately improved. But the slope of linear region, response time and contrast ratio deteriorated, especially the latter two. It can be assumed that these doping effects were due to the mechanistic change from liquid-gel separation to liquid-liquid separation by the fast heterogeneous nucleation rate caused by the increased nucleation at the surface of SiO2 nanoparticles. The marked deteriorations of falling response time and contrast ratio were due to well defined liquid crystal molecules in LC droplets, which induced slow and imperfect random rearrangement of LC molecules at the off state.

Published: February 2015

AbstractMolecular imaging plays an important role in the non-invasive diagnosis and the guiding or monitoring of disease treatment. Different imaging modalities have been developed, and each method possesses unique strengths. While a variety of molecules have been used previously in nuclear imaging, the exceptional properties of nanostructures in recent research enable the deployment of accurate and efficient diagnostic agents using radionuclide-nanostructures. This review focuses on the radionuclide labeling strategies of various nanostructures and their applications for multimodality tumor imaging.
Natural selection constrains personality and brain gene expression differences in Atlantic salmon (Salmo salar)
Authors: Thörnqvist Per-Ove , Höglund Erik , Winberg Svante 
Published: February 2015

ABSTRACT
In stream-spawning salmonid fishes there is a considerable variation in the timing of when fry leave the spawning nests and establish a feeding territory. The timing of emergence from spawning nests appears to be related to behavioural and physiological traits, e.g. early emerging fish are bolder and more aggressive. In the present study, emerging Atlantic salmon (Salmo salar L.) alevins were sorted into three fractions: early, intermediate and late emerging. At the parr stage, behaviour, stress responses, hindbrain monoaminergic activity and forebrain gene expression were explored in fish from the early and late emerging fractions (first and last 25%). The results show that when subjected to confinement stress, fish from the late emerging fraction respond with a larger activation of the brain serotonergic system than fish from the early fraction. Similarly, in late emerging fish, stress resulted in elevated expression of mRNA coding for serotonin 1A receptors (5-HT1A), GABA-A receptor-associated protein and ependymin, effects not observed in fish from the early emerging fraction. Moreover, fish from the early emerging fraction displayed bolder behaviour than their late emerging littermates. Taken together, these results suggest that time of emergence, boldness and aggression are linked to each other, forming a behavioural syndrome in juvenile salmon. Differences in brain gene expression between early and late emerging salmon add further support to a relationship between stress coping style and timing of emergence. However, early and late emerging salmon do not appear to differ in hypothalamus–pituitary–interrenal (HPI) axis reactivity, another characteristic of divergent stress coping styles.

Published: February 2015

Abstract
Chemically reduced graphene oxide (rGO) decorated with aliphatic dendrimers having gold nanoparticles either in their endo- or exo-positions was firstly formulated through fully noncovalent functionalization approaches. Noncovalent binding of aliphatic dendrimers specifically on rGO rather than on graphene oxide (GO) could be clearly visualized in transmission electron microscopy analysis.

Advance Selling: Effects of Interdependent Consumer Valuations and Seller’s Capacity
Authors: Yu Man , Kapuscinski Roman , Ahn Hyun-Soo 
Published: February 2015

We examine the impact of consumer valuation interdependence and capacity on a firm’s optimal selling strategies. We consider a seller who can offer a single product to consumers twice, in advance and in spot. Consumers choose whether and when to buy, but if they buy in advance, they are uncertain about their own valuations. Whether they buy in advance or in spot, consumers’ valuations are realized in the spot period and they may range from fully independent to perfectly correlated, creating markets with different characteristics of aggregate demand for the seller. Facing these consumers, the seller chooses a portion of the total capacity to offer in advance and prices in both periods. We describe how the optimal strategy and benefits of advance selling depend on the interdependence of consumer valuation, as well as capacity level and other market parameters. We find that a change in valuation interdependence can lead to dramatically different policies for the seller. For example, when individual valuations are highly diverse and the consumer population is large, the seller must offer a discount during advance selling but may limit the advance sales. On the other hand, when valuations are highly correlated, the seller can charge a premium price during advance selling. For the same valuation interdependence, the qualitative nature of the optimal strategy changes with available capacity.This paper was accepted by Martin Lariviere, operations management.
Stanislavsky’s musicality: Towards physicalization
Authors: Frendo Mario 
Published: February 2015

Abstract
This article investigates the musicality of Stanislavsky’s theatre practice by focusing specifically on his conceptions of rhythm and tempo-rhythm. It refers to the work Stanislavsky conducted during the 1918 Bolshoi Opera Studio and the 1935 Opera-Dramatic Studio. The article draws on recent scholarship on musicality in theatre in order to propose that although not immediately visible as an ‘outcome’ of his theatricality, Stanislavsky’s musicality was located beyond the limits of music as metaphor to theatrical activity, and was evident in processes of embodiment that Stanislavsky was developing with his actors. This rather broad musical dimension is foregrounded in Stanislavsky’s consistent attention to rhythm, and the ways rhythmic awareness affects the actor’s presence. This led to the development of the notion of tempo-rhythm. It will be argued that beyond its apparent dualistic nature, if reconsidered as a ‘relational dynamic’ tempo-rhythm emerges as a key element of Stanislavsky’s musicality. The author concludes that in his quest to promote acting as embodiment, Stanislavsky developed, through musicalized processes, strategies of physicalization of action that promoted acting beyond imitations of scripted texts.

When and How Students Take the Reins: Specifying Learner Initiatives in Tutoring Sessions with Preschool-Aged Children
Authors: DiFelice Box Catherine 
Published: February 2015

Abstract
For decades, scholars across disciplines have lauded educational settings in which students have the interactional space to take initiative (e.g. Dyson 1987; Manke 1997; Renne 1996; Shah et al. 2002). As such, initiatives of this kind are considered an important part of student-centered activities, which in turn lead to greater learning opportunities (Waring 2011). While much research has been devoted to examining contexts in which learner’s voices may be heard, scant attention has been paid to the particular kinds of talk that encourage them to initiate contribution or the ways in which such initiatives, when they do occur, serve to shape the pedagogical trajectory. By utilizing conversation analysis (CA) to study interactions in one-on-one mathematics tutoring sessions between an experienced teacher and preschool-aged children, this study extends the small but growing body of microanalytic work on learner initiatives. It aims to further specify the discursive practices that foster rich environments for learner-led contributions. It also considers how the contributions shape the ensuing lesson, and what such contributions relay to teachers about the learner’s understanding of a concept.
Intercultural Communication Systems and Discourses of Cultural Identity
Authors: Baraldi Claudio 
Published: February 2015

Abstract
The analysis of intercultural communication, which is adopted in mainstream applied linguistics and communication studies, aims to explain the meaning of cultural differences and identities in the present global world. The present analysis of intercultural communication is based on theories of cultural variability, which highlight the basic distinctions between values determining cultural differences and identities. Some studies in applied linguistics observe cultural variability as a discursive construction based on a form of epistemological essentialism, produced in the Western part of the world to give meaning to its hegemony. However, these studies share some epistemological foundations with theories of cultural variability. This paper proposes a theorization of intercultural communication, which explains cultural differences and identities as constructed in communication systems and based on their particular structural presuppositions. In this perspective, the hegemonic structure of intercultural communication is ethnocentrism, including the presuppositions of Us/Them basic distinction, positioning of individuals as members of cultural groups and normative expectations about displays of We-identities. This theorisation also provides an explanation of the discursive construction of new hybrid forms of identity, which are observed as a result of globalisation, and of the interdependence between local and global communication systems. Finally, this theorization leads to explain the meaning of intercultural dialogue, which is presented as an alternative to ethnocentrism. The open question regards the explanation of dialogue as either a new discursive construction of hegemonic Western culture or a new structure, introducing equality in participation, sensitivity for participants’ personal expressions and expectations of participants’ empowerment in local and global communication systems.
Towards a Model of Advanced Learners’ Vocabulary Acquisition: An Investigation of L2 Vocabulary Acquisition and Retention by Taiwanese English Majors
Authors: Reynolds Barry Lee , Wu Wei-Hua , Liu Hui-Wen , Kuo Shu-Yuan , Yeh Ching-Hua 
Published: February 2015

Abstract
Development of vocabulary is one of the fundamental elements for second language acquisition; it is important to meaning transfer and successful communication as well (Barcroft 2004). The purpose of the research reported in this paper was to investigate to what extent the characteristics of vocabulary affect Taiwanese English language majors’ second-language vocabulary acquisition and retention. This research builds upon similar research conducted by Willis and Ohashi (2012), which found a relationship between acquisition and a word’s frequency, cognateness, and length for Japanese learners of English. Our results indicate a significant relationship between acquisition and a word’s frequency, level of polysemy, and part of speech. Correlation results show that polysemy and frequency are both strongly related to acquisition. Nevertheless, a negative correlation between phonemes and acquisition was also shown. The findings indicate that high frequency words and polysemous words are both easily acquired and retained; in contrast, words with more phonemes require more effort by Taiwanese English language majors to learn and retain. Findings from a multiple regression analysis further suggest that high frequency polysemous nouns are easily acquired and retained by Taiwanese English language majors. Pedagogical implications concerning the variables investigated are provided.
