Low-Mass Dark Matter Search with the DarkSide-50 Experiment

Abstract: We present the results of a search for dark matter weakly interacting massive particles (WIMPs) in the mass range below 20 GeV/c2 using a target of low-radioactivity argon with a 6786.0 kg d exposure. The data were obtained using the DarkSide-50 apparatus at Laboratori Nazionali del Gran Sasso. The analysis is based on the ionization signal, for which the DarkSide-50 time projection chamber is fully efficient at 0.1 keVee. The observed rate in the detector at 0.5 keVee is about 1.5 event/keVee/kg/d and is almost entirely accounted for by known background sources. We obtain a 90% C.L. exclusion limit above 1.8 GeV/c2 for the spin-independent cross section of dark matter WIMPs on nucleons, extending the exclusion region for dark matter below previous limits in the range 1.8–6 GeV/c2.

Inhibition of experimental seizures in canines by repetitive vagal stimulation.

Abstract: Summary: Repetitive electrical stimulation of the canine cervical vagus nerve interrupts or abolishes motor seizures induced by strychnine and tremors induced by pentylenetetrazol (PTZ). Tremors were defined as rhythmic alternating contractions of opposing muscle groups, exerting much less force than seizure contractions. Seizures were induced by injection boluses of strychnine or PTZ at 1- to 4-min intervals until sustained muscle activity was observed electromyographically (EMG). Vagal stimulation terminated seizures in 0.5-5 s. There were prolonged periods with no spontaneous EMG activity after stimulation. The period of protection was approximately four times the stimulation period. The antiseizure actions of vagal stimulation were not altered by transection of the vagus distal to the stimulating electrode. Optimal stimulus parameters were estimated: strength, -20 V (electrode resistance 1-5 ω); frequency 20–30 Hz; duration, -0.2 ms. These data suggest that the antiseizure effects derive from stimulation of small-diameter afferent unmyelinated fibers in the vagus nerve. These results may form the basis of a new therapeutic approach to epilepsy.

Communicating About Grammar: A Task‐Based Approach

Abstract: Providing learners with grammar problems they must solve interactively integrates grammar instruction with opportunities for meaningful communication. This article reports the results of an exploratory study of the use of a communicative, grammar-based task in the college EFL classroom. The two research questions addressed are whether the task successfully promoted L2 linguistic knowledge of a specific grammar point and whether it produced the kind of negotiated interaction which has been assumed to facilitate L2 acquisition. The limited results of this investigation suggest that the grammar task encouraged communication about grammar and enabled EFL learners to increase their knowledge of a difficult L2 rule.

Applying an Emotion Regulation Framework to Integrative Approaches to Generalized Anxiety Disorder

Abstract: Integrative conceptualizations like that proposed byRoemer and Orsillo provide exciting new directions forunderstanding and treating generalized anxiety disorder(GAD). However, these approaches may be furtherstrengthened by adoption of an emotion regulationperspective. Persons with GAD may have difficulty un-derstanding their emotional experience and may pos-sess few skills to modulate their emotions. They mayexperience emotions as subjectively aversive and useworry and maladaptive interpersonal behaviors as de-fensive strategies to control, avoid, or blunt emotionalexperience. An emotion regulation perspective suggestsadding treatment components to help clients becomemore comfortable with arousing emotional experience,more able to access and utilize emotional informationin adaptive problem solving, and better able to modu-late emotional experience and expression according tocontextual demands.Key words: emotion regulation, generalized anxietydisorder.

Customer Engagement With Tourism Brands Scale Development and Validation

Abstract: Although customer engagement (CE) has emerged as a widely used term in many industries, including tourism and hospitality, academic research lacks a clear conceptualization and rigorous measurement of the construct. This study develops and validates a 25-item CE scale that comprises five factors: identification, enthusiasm, attention, absorption, and interaction. The scale, developed from a survey of hotel and airline customers, demonstrated strong psychometric properties across multiple samples and showed CE to exert a positive significant influence on behavioral intention of loyalty for both hotel and airline customers. The scale offers a framework for future empirical research in this increasingly important area, and it provides a useful tool for tourism practitioners to collect insights into customer psychological and behavioral connections with their brands beyond the service consumption experience.
