Flight Safety and its Reliance on Cultural Attributes
of Cabin Crew
Morteza Tehrani and Brett Molesworth
School of Aviation
Abstract
The role of cabin crew and their significance for cabin safety have been highlighted in
several air accidents some of which could have been avoided if cabin crew had revealed
the information they held. Nowadays major airlines embrace diverse cabin crew with various
cultures whose performance may be affected by their behaviours.
The diversities and interrelationship of cultures can produce friction which may disintegrate a
team and lose its synergy and cohesiveness. A good safety system should form a safety
culture to foresee all aspects of cultural attributes the cabin crew present as they are
selected from diverse groups and backgrounds.
This study will explore the attributes of the existing issues and the optimal character for the
cabin crew to perform a safe and efficient operation. The findings of this research should
highlight the weak areas of our flight operations.
In addition, it is anticipated that this study will develop a scientifically valid tool to identify
safety culture within the cabin area. This tool has the potential application for various
aviation organisations internationally. Furthermore, with minor modifications it is anticipated
that the tool could be adopted in other complex socio-technical environments such as
medicine, rail and marine.
Photoluminescence Study and Characterization of
Optically Trapped InP Semiconductor Nanowires
Abstract
Fan Wang and Peter Reece
School of Physics
My work is mainly using optical tweezers to research physical and optical properties of
semiconductor nanowires, especially InP nanowire with length of 5-15μm and diameter of 30-
150nm. Recently semiconductor nanowires attract more interest for nano-scale
optoelectronic integrated circuits and devices, due to its potentially function as both
electrical and optical conduits. While optical tweezers is a powerful tool for manipulating
single nanowire; combined with micro-photoluminescence it is effective for characterization
and application of individual semiconductor nanowires. By means of back focal plane
interferometery, the motion and trap stiffness of trapped nanowire can be quantitatively
investigated, which can be used to research Brownian dynamics of nanowires and two
nanowires’ coupling dynamics. An IR trapping laser (1064nm) and a visible excitation laser
(514.5nm) are used to characterize single nanowires’ photoluminescence (PL) property
including direct PL, two-photon absorption PL and second harmonic generation. For InP
nanowire the PL property for different crystalline phases is researched also. Combined wave
guiding and PL properties of nanowires can be used to nanowire scanning probe. While
combing wave guiding with Bessel beam excitation, the potential trapping nanowire laser
may be achieved.
