Cultural impact on customer perception of service quality in the hotel industry: A comparative study of Eastern and Western respondents
The purpose of the study was to investigate cultural aspects that influence customer perception of service quality in the hotel industry, specifically those that influence Eastern and Western respondents. A questionnaire was developed to assess cultural differences on perceptions, which included a modified version of the SERVQUAL scales, an instrument used to measure service quality. The convenience sample consisted of students enrolled in the MBA program at a Western university (N=152; Eastern=57.9%, Western=34.9%, Other=7.2%). Findings indicated that there were no significant differences between Eastern and Western cultures in perceptions of service quality. A sample questionnaire is included
Electromagnetic emissions from near-horizon region of an extreme Kerr-Taub-Nut black hole
We have studied electromagnetic line emissions from near-horizon region in
the extremal Kerr-Taub-NUT black hole spacetime and then probe the effects of
NUT charge on the electromagnetic line emissions. Due to the presence of the
NUT charge, the equatorial plane is no more a symmetry plane of the KTN
spacetime, which leads to that the dependence of electromagnetic line emission
on the NUT charge for the observer in the Southern Hemisphere differs from that
in the Northern one. Our result indicate that the electromagnetic line emission
in the Kerr-Taub-NUT black hole case is brighter than that in the case of Kerr
black hole for the observer in the equatorial plane or in the Southern
Hemisphere, but it becomes more faint as the observer's position deviates far
from the equatorial plane in the Northern one. Moreover, we also probe effects
of redshift factor on electromagnetic emission from near-horizon region in the
extremal Kerr-Taub-NUT black hole spacetime.Comment: 18 pages, 7 figure
Long-term Blood Pressure Prediction with Deep Recurrent Neural Networks
Existing methods for arterial blood pressure (BP) estimation directly map the
input physiological signals to output BP values without explicitly modeling the
underlying temporal dependencies in BP dynamics. As a result, these models
suffer from accuracy decay over a long time and thus require frequent
calibration. In this work, we address this issue by formulating BP estimation
as a sequence prediction problem in which both the input and target are
temporal sequences. We propose a novel deep recurrent neural network (RNN)
consisting of multilayered Long Short-Term Memory (LSTM) networks, which are
incorporated with (1) a bidirectional structure to access larger-scale context
information of input sequence, and (2) residual connections to allow gradients
in deep RNN to propagate more effectively. The proposed deep RNN model was
tested on a static BP dataset, and it achieved root mean square error (RMSE) of
3.90 and 2.66 mmHg for systolic BP (SBP) and diastolic BP (DBP) prediction
respectively, surpassing the accuracy of traditional BP prediction models. On a
multi-day BP dataset, the deep RNN achieved RMSE of 3.84, 5.25, 5.80 and 5.81
mmHg for the 1st day, 2nd day, 4th day and 6th month after the 1st day SBP
prediction, and 1.80, 4.78, 5.0, 5.21 mmHg for corresponding DBP prediction,
respectively, which outperforms all previous models with notable improvement.
The experimental results suggest that modeling the temporal dependencies in BP
dynamics significantly improves the long-term BP prediction accuracy.Comment: To appear in IEEE BHI 201
