The Influence of Hotel Customer Demographics on Their Trust on EWOM

The advancement of internet technologies increased the number of travelers who are using the internet to seek destination information, and one of the most important information sources when consumer is making a purchase decision is EWOM. It has higher credibility, empathy, and relevance than marketer-created sources of information. While a lot of studies addressed the impact of EWOM on customer trust and purchasing decision, only few studies have discussed the role of receiver's demographic characteristics in determining the influence of EWOM. So, this study comes to meet this gap and identify the determinants that affect the customer trust of EWOM in hotel industry, and shows the role of demographic characteristics in determining the influence of "EWOM" on hotel customer trust. The study targeted the hotel customers of Sharm El sheikh city using a questionnaire form. Two quantitative analysis methods were used; linear regression to test the relation between EWOM determinants and the customer's trust of EWOM, and the compare mean function with ANOVA analysis to identify the differences between categories of respondents due to their demographic characteristics. Result of the study would assist hoteliers identify the determinants of EWOM that can influence customers trust, and how to manage these determinants with the different demographic market segments.

6 Dynamics of Jupiter ' s Atmosphere

Jupiter has half a dozen eastward jet streams in each hemisphere. On average, Earth has only one in each hemisphere. Jupiter has weather patterns ("storms") that last for centuries. Earth has stationary weather patterns fixed to the topography, but the average lifetime of a traveling storm is rvl week. Jupiter has no topography, i.e., no continents or oceans; its atmosphere merges smoothly with the planet's fluid interior. Absorbed sunlight (power per unit area) at Jupiter is only 3.3% that at Earth, yet Jupiter's winds are 3-4 times stronger. The ratio of Jupiter's internal power to absorbed solar power is 0. 7. On Earth the ratio is 2 x 10. Jupiter's hydrologic cycle is fundamentally different from Earth's because it has no ocean, but lightning occurs on both planets. On Earth, electrical charge separation is associated with falling ice and rain. On Jupiter, the separation mechanism is still to be determined. The winds of Jupiter are only 1/3 as strong as those of Saturn and Neptune, and yet the other giant planets have less sunlight and less internal heat than Jupiter. Earth probably has the weakest winds of any planet, although its absorbed solar power per unit area is largest. All the giant planets are banded. Even Uranus, whose rotation axis is tipped 98° relative to its orbit axis, exhibits banded cloud patterns and east-west (zonal) jets. All have long-lived storms, although Jupiter's Great Red Spot (GRS), which may be hundreds of years old, seems to be the oldest.
Welding of Lightweight Aluminum-Lithium Alloys Information on the welding of various aluminum-lithium alloys is reviewed

Lithium-containing aluminum alloys have generated much interest in the aerospace industry because lithium additions to aluminum can decrease the density and improve the stiffness compared to conventional aluminum alloys of comparable strength. In this paper, published studies of the structure and properties of welded aluminum-lithium alloys are discussed. The weldability characteristics of these lightweight alloys using gas metal arc, gas tungsten arc, electron beam and laser beams are summarized. While the alloys appear to be easily fusion weldable, they may be prone to problems of weld porosity, cracking, poor penetration and low joint efficiency. The effects of heat treatment on postweld joint efficiency are also highlighted. Intrinsic problems associated with conventional welding were partially eliminated through laser beam welding. The laser beam weld studies revealed a low degree of surface degradation, an absence of porosity and attractive joint efficiency. The results delineated in the published literature suggest that future studies must concentrate on a more comprehensive and systematic approach to an evaluation of properties if the use of welded aluminum-lithium structures is to be rapidly accepted in numerous industrial applications.
Imaging study of NGC 3372, the Carina nebula — II. Evidence of activity in the complex Trumpler 14/Car I photodissociation region

We present the results of an imaging survey, from the optical to the mid-infrared, of the dark cloud associated with Car I, a dense cloud that is subject to an intense ultraviolet radiation field from the rich stellar cluster Trumpler 14. New ground-based broad- and narrowband near-infrared and narrow-band optical images are analysed in combination with archived Spitzer/InfraRed Array Camera (IRAC) images to study this photodissociation region (PDR) and the triggering of a new generation of stars within the cloud, particularly close to its edges. Evidence is given of a clumpy morphology of the dense cloud. The ionization/dissociation front is delineated at the edges of these clumps. The existence of a number of embedded lowto intermediate-mass pre-main-sequence objects is confirmed by their considerable infrared excesses arising from discs and/or detectable X-ray emission. Most of the young stellar objects (YSOs) are located on or just behind ionization fronts, though a few are also outside the cloud. The infrared properties of the YSOs are discussed. Two Class I objects stand out, one of them is an FU Orionis system candidate that had an outburst of more than 3 mag in K between 1993 and 2003, with further evidence that it occurred in the 2000‐02 period. Molecular hydrogen line filamentary emission behind the Balmer and Brackett lines along the ionization front is seen delineating the edges of the dense cloud. This emission is also seen in all IRAC images. The diffuse, filamentary emission is very similar in all four 3.6, 4.5, 5.8 and 8 μm bands, though there seem to be subtle differences. Across a bright section of the ionization/dissociation front, we found that, within the observational uncertainties, the maximum emission in all four IRAC channels coincides with that of H2 2.12 μm. The western, embedded, dissociation front close to the CO peak (Car I-W) is seen delineated by a bright, long bar of emission in the 3‐12 μm images, in the Midcourse Space Experiment bands A and C and also in radio continuum and hydrogen line emission. These occur in the vicinity of a region of previously reported strong [C I], [C II] and [O I] emission, tracers of PDRs. A few bright, compact knots of H2 emission, some possibly associated with [S II] emission, are found within the cloud. These may be shock-excited.
A low‐cost, portable, and practical LAMP device for point‐of‐diagnosis in the field

Transition of rapid, ready‐to‐use, and low‐cost nucleic acid‐based detection technologies from laboratories to points of sample collection has drastically accelerated. However, most of these approaches are still incapable of diagnosis starting from sampling through nucleic acid isolation and detection in the field. Here we developed a simple, portable, low‐cost, colorimetric, and remotely controllable platform for reliable, high‐throughput, and rapid diagnosis using loop‐mediated isothermal amplification (LAMP) assays. It consists of a thermally isolated cup, low‐cost electronic components, a polydimethylsiloxane sample well, and a fast prototyped case that covers electronic components. The steady‐state temperature error of the system is <1%. We performed LAMP, Colony‐LAMP, and Colony polymerase chain reactions (PCRs) using the yaiO2 primer set for Escherichia coli and Pseudomonas aeruginosa samples at 65°C and 30 min. We detected the end‐point colorimetric readouts by the naked eye under day light. We confirmed the specificity and sensitivity of our approach using pure genomic DNA and crude bacterial colonies. We benchmarked our Colony‐LAMP detection against Colony PCR. The number of samples tested can easily be modified for higher throughput in our system. We strongly believe that our platform can greatly contribute rapid and reliable diagnosis in versatile operational environments.
Biomedical Application, Patent Repository, Clinical Trial and Regulatory Updates on Hydrogel: An Extensive Review

Hydrogels are known for their leading role in biomaterial systems involving pharmaceuticals that fascinate material scientists to work on the wide variety of biomedical applications. The physical and mechanical properties of hydrogels, along with their biodegradability and biocompatibility characteristics, have made them an attractive and flexible tool with various applications such as imaging, diagnosis and treatment. The water-cherishing nature of hydrogels and their capacity to swell—contingent upon a few ecological signals or the simple presence of water—is alluring for drug conveyance applications. Currently, there are several problems relating to drug delivery, to which hydrogel may provide a possible solution. Hence, it is pertinent to collate updates on hydrogels pertaining to biomedical applications. The primary objective of this review article is to garner information regarding classification, properties, methods of preparations, and of the polymers used with particular emphasis on injectable hydrogels. This review also covers the regulatory and other commerce specific information. Further, it enlists several patents and clinical trials of hydrogels with related indications and offers a consolidated resource for all facets associated with the biomedical hydrogels.
IFU Spectroscopy of Southern Planetary Nebulae V: Low-Ionisation Structures

Abstract In this fifth paper of the series, we examine the spectroscopy and morphology of four southern Galactic planetary nebulae Hen 2-141, NGC 5307, IC 2553, and PB 6 using new integral field spectroscopy data. The morphologies and ionisation structures of the sample are given as a set of emission-line maps. In addition, the physical conditions, chemical compositions, and kinematical characteristics of these objects are derived. The results show that PB 6 and Hen 2-141 are of very high excitation classes and IC 2553 and NGC 5307 are mid to high excitation objects. The elemental abundances reveal that PB 6 is of Type I, Hen 2-141 and IC 2553 are of Type IIa, and NGC 5307 is of Type IIb/III. The observations unveil the presence of well-defined low-ionisation structures or ‘knots’ in all objects. The diagnostic diagrams reveal that the excitation mechanism of these knots is probably by photoionisation of dense material by the nebular central stars. The physical analysis of six of these knots show no significant differences with their surrounding nebular gas, except their lower electron densities. In spite of the enhancement of the low-ionisation emission lines of these knots, their chemical abundances are nearly comparable to their surrounding nebulae, with the exception of perhaps slightly higher nitrogen abundances in the NGC 5307 knots. The integrated spectrum of IC 2553 reveals that nearly all key lines that have led researchers to characterise its central star as a weak-emission line star type are in fact of nebular origin.
Knowledge representation and interactive learning of domain knowledge for human-robot interaction

This paper describes an integrated architecture for representing, reasoning with, and interactively learning domain knowledge in the context of human-robot collaboration. Specifically, Answer Set Prolog, a declarative language, is used to represent and reason with incomplete commonsense knowledge about the domain. Non-monotonic logical reasoning identifies knowledge gaps and guides the interactive learning of relations that represent actions, and of axioms that encode affordances and action preconditions and effects. Learning uses probabilistic models of uncertainty, and observations from active exploration, reactive action execution, and human (verbal) descriptions. The learned actions and axioms are used for subsequent reasoning. The architecture is evaluated on a simulated robot assisting humans in an indoor domain.
Measurements of High-Energy Neutrons Penetrated Through Concrete Shields Using Self-TOF, NE213, and Activation Detectors

Abstract Neutron energy spectra penetrated through concrete shields were measured using three types of high-energy neutron detectors: the Self-TOF detector, an NE213 organic liquid scintillator, and Bi and C activation detectors, which have been newly developed by a group at the Heavy-Ion Medical Accelerator in Chiba (HIMAC) facility of the National Institute of Radiological Sciences, Japan. Neutrons were generated by bombarding 400 MeV/nucleon C ions on a thick (stopping-length) copper target. The neutron spectra were obtained through an unfolding code with their response functions and compared with LAHET and MCNPX calculations combined with the LA150 cross-section library. The calculations tend to overestimate with increasing the shielding thickness compared to the experimental results. The neutron fluence measured by the NE213 detector was simulated by the track length estimator in the MCNPX code, and the contribution of the room-scattered neutrons was evaluated. The neutron fluence attenuation length was obtained from the experiment for each detector and the calculation in the energy range of 20 to 800 MeV.
Visual Analytics of Dynamic Interplay Between Behaviors in MMORPGs

The rapid development of massively multiplayer online role-playing games (MMORPGs) has led operators to record huge amounts of fine-grained data from the in-game activities of players. These data provide considerable opportunities with which to study the dynamic interplay among player behaviors and investigate the roles of various social structures that underlie such interplay. However, modeling and visualizing these behavioral data remain a challenge. In this study, we propose a novel influence-susceptible model to measure the dynamic interplay among multiple behaviors. Based on this model, we introduce a new visual analytics system called BeXplorer. BeXplorer enables analysts to interactively explore the dynamic interplay between player purchase and communication behaviors and to examine the manner in which this interplay is bound by social structures where players are embedded.
popharvest: An R package to assess the sustainability of harvesting regimes of bird populations

Abstract Bird harvest for recreational purposes or as a source for food is an important activity worldwide. Assessing or mitigating the impact of these additional sources of mortality on bird populations is therefore crucial issue. The sustainability of harvest levels is however rarely documented, because knowledge of their population dynamics remains rudimentary for many bird species. Some helpful approaches using limited demographic data can be used to provide initial assessment of the sustainable use of harvested bird populations, and help adjusting harvest levels accordingly. The Demographic Invariant Method (DIM) is used to detect overharvesting. In complement, the Potential Take Level (PTL) approach may allow setting a level of take with regard to management objectives and/or to assess whether current harvest levels meet these objectives. Here, we present the R package popharvest that implements these two approaches in a simple and straightforward way. The package provides users with a set of flexible functions whose arguments can be adapted to existing knowledge about population dynamics. Also, popharvest enables users to test scenarios or propagate uncertainty in demographic parameters to the assessment of sustainability through easily programming Monte Carlo simulations. The simplicity of the package makes it a useful toolbox for wildlife managers or policymakers. This paper provides them with backgrounds about the DIM and PTL approaches and illustrates the use of popharvest's functionalities in this context.
Fabrication and characterization of germanium-on-insulator through epitaxy, bonding, and layer transfer

A scalable method to fabricate germanium on insulator (GOI) substrate through epitaxy, bonding, and layer transfer is reported. The germanium (Ge) epitaxial film is grown directly on a silicon (Si) (001) donor wafer using a “three-step growth” approach in a reduced pressure chemical vapour deposition. The Ge epilayer is then bonded and transferred to another Si (001) wafer to form the GOI substrate. The Ge epilayer on GOI substrate has higher tensile strain (from 0.20% to 0.35%) and rougher surface (2.28 times rougher) compared to the Ge epilayer before transferring (i.e., Ge on Si wafer). This is because the misfit dislocations which are initially hidden along the Ge/Si interface are now flipped over and exposed on the top surface. These misfit dislocations can be removed by either chemical mechanical polishing or annealing. As a result, the Ge epilayer with low threading dislocations density level and surface roughness could be realized.
A Dynamic Model of Employer-Provided Health Insurance and Job Mobility

We estimate the eect of employer-provided health insurance (EPHI) on job mobility via a dynamic model of joint employment and health insurance decision in the presence of uncertainty about wage rate and health status transitions. The model is based on a Markov decision process in which a hedonic wage approach provides an economic rationale for the dierent choices and health insurance serves as an input to the health production process. Including health transitions in the model helps us to understand how the availability of EPHI (positive job characteristic) and holding EPHI (the wage-health insurance tradeo) enter into the individuals’ decisions. The model is estimated using the 1999-2000 Medical Expenditure Panel Survey (MEPS) panel 4 and the results show that the “pure” eects
Identification of the Quasi-Static and Dynamic Behaviour of Projectile-Core Steel by Using Shear-Compression Specimens

Armour-Piercing (AP) projectiles constitute a major threat to be considered for the design of bi-layer-armour configurations constructed using a ceramic front plate backed with a composite/metal layer. When they are not made of tungsten-carbide the cores of these projectiles are made of hard steel, and are the main part that defines the penetration performance of the projectile. However, due to specific testing difficulties, the dynamic behaviour of these high-strength steel AP projectiles has not been investigated in sufficient detail. In this study, a detailed experimental investigation of the dynamic behaviour of the steel used for the steel core of 7.62 mm BZ-type AP projectiles was analysed through the use of Shear-Compression Specimens (SCS). In this study, results from both quasi-static and dynamic experiments were examined. The data processing method employed was set and validated based on numerical simulations. Both quasi-static and dynamic SCS experiments were done with the steel tested which clearly indicated the steel cores exhibit a very high elastic limit, little strain-hardening, and very little strain-rate sensitivity despite the wide range of strain-rates considered. This experimental characterisation paves the way to the numerical modelling for the analysis of ballistic impact of 7.62 mm AP projectile against lightweight armour configurations.
PARAMETERIZATION OF A WAVE-DEPENDENT SURFACE ROUGHNESS : A STEP TOWARDS A FULLY COUPLED ATMOSPHERE-OCEAN-SEA ICE-WAVE SYSTEM

Wind-waves are located at the interface between the atmosphere and ocean and affect exchanges of momentum, heat, energy and mass between oceanic and atmospheric boundary layers (Sullivan and McWilliams 2010, Cavaleri et al. 2012, Babanin et al. 2012). In particular, waves play an active role in the transfer of momentum between atmosphere and ocean. In the atmospheric model, momentum flux is partly determined by the surface roughness length. It is usually calculated as a function of the surface wind speed (Charnock, 1955). However, previous studies have shown that the roughness is related to the sea state (defined by wave age, wave steepness and/or whitecapping induced spray) and that its estimation can be improved using a wave-dependent parameterization.
A Novel Phase Current Reconstruction Method for a Three-Level Neutral Point Clamped Inverter (NPCI) with a Neutral Shunt Resistor

This paper presents three phase current reconstruction methods for a three-level neutral point clamped inverter (NPCI) by measuring the voltage of a shunt resistor placed in the neutral point of the inverter. In order to accurately acquire the phase currents from the shunt resister, the dwell time of the active voltage vectors need to exceed the minimum time. On the other hand, if the time of active voltage is shorter than the minimum time, the current measurement becomes impossible. In this paper, unmeasurable regions for current are classified into three areas. Area 1 is a region in which both phase currents can be measure. Therefore, it is not necessary to restore the current. In Area 2, only one phase current can be measured. Thus, an estimation or restoration method is needed to measure another phase current. In this paper, the current estimation method using an electrical model of the motor is proposed. Area 3 is the region in which both phase currents can not be measured. In this case, it is necessary to move the voltage vector to the current measurable area by injecting the voltage. In this paper, Area 3 is divided into 36 sectors to inject optimal voltage. The proposed methods have the advantages of high current measurement accuracy and low THD (total harmonic distortion). The effectiveness of the proposed methods are verified through experimental results.
Evidence of Some Major Structures Underlying the Douala Sedimentary Sub-Basin: West African Coastal Basin

Gravity data have been processed in the Douala sedimentary sub-basin in a section consisting of a set of 116 gravity data points located between latitudes 3°03'N and 4°06'N and longitudes 9°00'E and 10°00'E. The established Bouguer anomaly fields and the Residual anomaly fields, extracted by upward continuation at an optimum height of 30 km, were both characterized by considerably high positive anomalies. These anomalies showed many ring-like positive gravity anomaly contour lines in the study region. Gravity gradients were analysed using the multi-scale horizontal derivative of the vertical derivative (MSHDVD) method, and this excluded the existence of fault lines across this region. Amplitude spectrum was used to estimate the potential field source at a depth of about 4.8 km. The ideal body theory capable of handling sparse data contaminated with noise was applied along a 50.2 km WWS-EEN profile to determine a density contrast of 0.266 g/cm3. Using these results as constraints, 2.5 D modelling carried out along this profile presented two major blocks with density contrast of 0.266 g/cm3. The first block is probably an intrusive igneous body with a density of about 2.77 g/cm3 , having an average thickness of about 26 km with its top and base lying at depths of about 4.25 km and 30.25 km respectively. The second block is likely a pillar of igneous material, located at a depth of about 10.77 km with a density of about 2.77 g/cm3 whose base goes deep down beyond the crust-mantle boundary. These results support previous findings that there are similarities between the Douala sedimentary sub-basin and the coastal sedimentary basin of Mauritania-Senegal and thus foster the suggestions of a more extensive movement that would have affected the whole of the West African coast.
