The Examination Of Entertainment Product Performance In Macau
Macau surpassed Las Vegas as the top gaming destination many years ago. Entertainment is a crucial element in many gambling destinations. Associating entertainment and gambling helped create a more appealing image and package of gambling destination. This study investigated the performance of entertainment products in Macau. This study used convenience sampling to collect 300 usable questionnaires from three tourists’ departure spots. Respondents were asked to evaluate the importance and performance of seven categories of entertainment products. The most important entertainment products were Family Fun and Show. Most people did not think Beauty and Wellness, or Sports and Recreation were important. Many people have the impression that Gambling is one of the most important entertainment products in Macau; however, in our sample, Gambling was ranked as the second most important entertainment product. Government and entertainment providers should continue their effort to provide more Family Fun and Shows to fulfill the needs of visitors
Differential measurement of atmospheric refraction with a telescope with double fields of view
For the sake of complete theoretical research of atmospheric refraction, the
atmospheric refraction under the condition of lower angles of elevation is
still worthy to be analyzed and explored. In some engineering applications, the
objects with larger zenith distance must be observed sometimes. Carrying out
observational research of the atmospheric refraction at lower angles of
elevation has an important significance. It has been considered difficult to
measure the atmospheric refraction at lower angles of elevation. A new idea for
determining atmospheric refraction by utilizing differential measurement with
double fields of view is proposed. Taking the observational principle of
HIPPARCOS satellite as a reference, a schematic prototype with double fields of
view was developed. In August of 2013, experimental observations were carried
out and the atmospheric refractions at lower angles of elevation can be
obtained by the schematic prototype. The measured value of the atmospheric
refraction at the zenith distance of 78.8 degree is , and the
feasibility of differential measurement of atmospheric refraction with double
fields of view was justified. The limitations of the schematic prototype such
as inadequate ability of gathering light, lack of accurate meteorological data
recording and lower automatic level of observation and data processing were
also pointed out, which need to be improved in subsequent work.Comment: 10 pages, 6 figure
An empirical study on cultural identity measurement and its influence mechanism among heritage tourists
In the effort to integrate culture and tourism, an important strategy for the prosperity and sustainability of tourism, it is necessary to factor in tourists’ cultural identity and emotional interaction with cultural heritage to keep pace with the trends of cultural heritage tourism. Drawing on in-depth interviews and software such as Nvivo and Smart-PLS, this study aims to develop and verify cultural identity measures for cultural heritage tourists, construct a theoretical model of cultural identity, travel experience, place attachment, satisfaction, and revisit intention, and verify the theoretical relationship between these dimensions in the Archaeological Ruins of Liangzhu City. The results show that cultural identity is positively associated with travel experience and place attachment but not significantly associated with satisfaction; travel experience is positively associated with place attachment and revisit intention; place attachment is positively associated with satisfaction; place attachment is positively associated with revisit intention; satisfaction is positively associated with revisit intention. This qualitative and quantitative research enriches the theoretical achievements concerning cultural identity among cultural heritage tourists and proposes recommendations for management practice accordingly
Observation of prolonged coherence time of the collective spin wave of atomic ensemble in a paraffin coated Rb vapor cell
We report a prolonged coherence time of the collective spin wave of a thermal
87Rb atomic ensemble in a paraffin coated cell. The spin wave is prepared
through a stimulated Raman Process. The long coherence time time is achieved by
prolonging the lifetime of the spins with paraffin coating and minimize
dephasing with optimal experimental configuration. The observation of the long
time delayed-stimulated Stokes signal in the writing process suggests the
prolonged lifetime of the prepared spins; a direct measurement of the decay of
anti-Stokes signal in the reading process shows the coherence time is up to 300
us after minimizing dephasing. This is one hundred times longer than the
reported coherence time in the similar experiments in thermal atomic ensembles
based on the Duan-Lukin-Cirac-Zoller (DLCZ) and its improved protocols. This
prolonged coherence time sets the upper limit of the memory time in quantum
repeaters based on such protocols, which is crucial for the realization of
long-distance quantum communication. The previous reported fluorescence
background in the writing process due to collision in a sample cell with buffer
gas is also reduced in a cell without buffer gas.Comment: 4 pages, 4 figure
Analytic study of superradiant stability of Kerr-Newman black holes under charged massive scalar perturbation
The superradiant stability of a Kerr-Newman black hole and charged massive
scalar perturbation is investigated. We treat the black hole as a background
geometry and study the equation of motion of the scalar perturbation. From the
radial equation of motion, we derive the effective potential experienced by the
scalar perturbation. By a careful analysis of this effective potential, it is
found that when the inner and outer horizons of Kerr-Newman black hole satisfy
and the charge-to-mass ratios of scalar
perturbation and black hole satisfy , the
Kerr-Newman black hole and scalar perturbation system is superradiantly stable.Comment: 7 pages, references adde
Experimental Trapped-ion Quantum Simulation of the Kibble-Zurek dynamics in momentum space
The Kibble-Zurek mechanism is the paradigm to account for the nonadiabatic
dynamics of a system across a continuous phase transition. Its study in the
quantum regime is hindered by the requisite of ground state cooling. We report
the experimental quantum simulation of critical dynamics in the
transverse-field Ising model by a set of Landau-Zener crossings in
pseudo-momentum space, that can be probed with high accuracy using a single
trapped ion. We test the Kibble-Zurek mechanism in the quantum regime in the
momentum space and find the measured scaling of excitations is in accordance
with the theoretical prediction.Comment: 10 pages, 3 figures Published in Scientific Reports,
