Impact of Airbnb on customers' behaviour in the UK hotel industry
Airbnb is one of the sectors of the sharing economy that is disrupting the hotel industries. In order to find approaches for hotels to mitigate the threat from Airbnb, this research will focus on the major elements influencing customers to choose Airbnb and the issues for the future of the hotel industry. Previous studies have looked at how Airbnb influences customer behaviour, and the impact of Airbnb on the hotel industry, but so far no study has been conducted focusing on the impact of Airbnb on the UK hotel industry. Therefore the purpose of this research is to evaluate the impact of Airbnb on customers’ behaviour within the UK hotel industry in order to determine how the hotel sectors can mitigate the threats posed by Airbnb. This paper highlights managerial and industrial implications
Engineering Automation for Reliable Software Interim Progress Report (10/01/2000 - 09/30/2001)

Research Triangle Park, NC 27709-2211The objective of our effort is to develop a scientific basis for producing reliable
software that is also flexible and cost effective for the DoD distributed software domain.
This objective addresses the long term goals of increasing the quality of service provided
by complex systems while reducing development risks, costs, and time. Our work focuses on
"wrap and glue" technology based on a domain specific distributed prototype model. The key
to making the proposed approach reliable, flexible, and cost-effective is the automatic
generation of glue and wrappers based on a designer's specification. The "wrap and glue"
approach allows system designers to concentrate on the difficult interoperability problems
and defines solutions in terms of deeper and more difficult interoperability issues, while
freeing designers from implementation details. Specific research areas for the proposed
effort include technology enabling rapid prototyping, inference for design checking,
automatic program generation, distributed real-time scheduling, wrapper and glue
technology, and reliability assessment and improvement. The proposed technology will be
integrated with past research results to enable a quantum leap forward in the state of the
art for rapid prototyping.U. S. Army Research Office P.O. Box 12211 Research Triangle Park, NC 27709-22110473-MA-SPApproved for public release; distribution is unlimited
Quantum correlations and violation of Bell inequality induced by External Field in a two photon radiative cascade
We study the polarization dependent second order correlation of a pair of
photons emitted in a four level radiative cascade driven by an external field.
It is found that the quantum correlations of the emitted photons, degraded by
the energy splitting of the intermediate levels in the radiative cascade can be
efficiently revived by a far detuned external field. The physics of this
revival is linked to an induced stark shift and the formation of dressed states
in the system by the non-resonant external field. Further, we investigated the
competition between the effect of the coherent external field and incoherent
dephasing of the intermediate levels. We found that the degradation of quantum
correlations due to the incoherent dephasing can be content for small dephasing
with the external field. We also studied the non-locality of the correlations
by evaluating the Bell's inequality in the linear polarization basis for the
radiative cascade. We find that the Bell parameter decreases rapidly with
increase in the intermediate level energy splitting or incoherent dephasing
rate to the extent that there is no violation. However, the presence of an
external field leads to control over the degrading mechanisms and preservation
of nonlocal correlation among the photons. This in turn can induce, violation
of Bell's inequality in the radiative cascade for arbitrary intermediate level
splitting and small incoherent dephasing

Synthetic gauge potential and effective magnetic field in a Raman medium undergoing molecular modulation
We theoretically demonstrate non-trivial topological effects for a probe
field in a Raman medium undergoing molecular modulation processes. The medium
is driven by two non-collinear pump beams. We show that the angle between the
pumps is related to an effective gauge potential and an effective magnetic
field for the probe field in the synthetic space consisting of a synthetic
frequency dimension and a spatial dimension. As a result of such effective
magnetic field, the probe field can exhibit topologically-protected one-way
edge state in the synthetic space, as well as Landau levels which manifests as
suppression of both diffraction and sideband generation. Our work identifies a
previously unexplored route towards creating topological photonics effects, and
highlights an important connection between topological photonics and nonlinear
optics
