Students interviewing students: the Aston-Hong Kong Project
This article provides an account of undergraduate sociology students conducting indepth interviews with international students from Hong Kong. The research is locating in a broader project of identifying rationales for the recruitment of international students. One of the shortcomings of previous research was that the student voice and rationale were missing. We have addressed this by involving undergraduate researchers in the collection and analysis of data. This project report draws on one of the reflections of the student researcher
Internet videoconferencing for patient-clinician consultations in long-term conditions : a review of reviews and applications in line with guidelines and recommendations
Introduction
The use of internet videoconferencing in healthcare settings is widespread, reflecting the normalisation of this mode of communication in society and current healthcare policy. As the use of internet videoconferencing is growing, increasing numbers of reviews of literature are published.
Methods
The authors conducted a review of the existing reviews of literature relating to the use of internet videoconferencing for consultations between healthcare professionals and patients with long-term conditions in their own home. The review was followed with an assessment of UK National Institute for Health and Clinical Excellence guidelines for patient care in the context of common long-term illnesses to examine where videoconferencing could be implemented in line with these recommendations.
Results
The review of reviews found no formal evidence in favour of or against the use of internet videoconferencing. Patients were satisfied with the use of videoconferencing but there was limited evidence that it led to a change in health outcomes. Evidence of healthcare professional satisfaction when using this mode of communication with patients was limited. The review of guidelines suggested a number of opportunities for adoption and expansion of internet videoconferencing. Implementing videoconferencing in line with current evidence for patient care could offer support and provide information on using a communication channel that suits individual patient needs and circumstances. The evidence base for videoconferencing is growing, but there is still a lack of data relating to cost, ethics and safety.
Conclusions
While current evidence base for the internet videoconferencing is equivocal, it is likely to change as more research is undertaken and evidence published. With more videoconferencing services added in more contexts, research needs to explore how internet videoconferencing can be implemented in ways that it is valued by patients and clinicians, and how it can fit within organizational and technical infrastructure of the healthcare services
Non-equilibrium emission of complex fragments from p+Au collisions at 2.5 GeV proton beam energy
Energy and angular dependence of double differential cross sections
d/ddE was measured for reactions induced by 2.5 GeV protons
on Au target with isotopic identification of light products (H, He, Li, Be, and
B) and with elemental identification of heavier intermediate mass fragments (C,
N, O, F, Ne, Na, Mg, and Al). It was found that two different reaction
mechanisms give comparable contributions to the cross sections. The
intranuclear cascade of nucleon-nucleon collisions followed by evaporation from
an equilibrated residuum describes low energy part of the energy distributions
whereas another reaction mechanism is responsible for high energy part of the
spectra of composite particles. Phenomenological model description of the
differential cross sections by isotropic emission from two moving sources led
to a very good description of all measured data. Values of the extracted
parameters of the emitting sources are compatible with the hypothesis claiming
that the high energy particles emerge from pre-equilibrium processes consisting
in a breakup of the target into three groups of nucleons; small, fast and hot
fireball of 8 nucleons, and two larger, excited prefragments, which
emits the light charged particles and intermediate mass fragments. The smaller
of them contains 20 nucleons and moves with velocity larger than the CM
velocity of the proton projectile and the target. The heavier prefragment
behaves similarly as the heavy residuum of the intranuclear cascade of
nucleon-nucleon collisions. %The mass and charge dependence of the total
production cross %sections was extracted from the above analysis for all
observed %reaction products. This dependence follows the power low behavior

Associated strangeness production in pp collisions near threshold
Motivated by the ongoing discussion concerning the nature of the scalar
resonances f0(980) and a0(980), the COSY-11 collaboration has taken exclusive
data on the pp->ppK+K- reaction near the production threshold. A first total
cross section sigma=(1.80+-0.27+0.28-0.35)nb for the excess energy Q=17 MeV has
been determined. In contrary to the eta, omega and eta' single meson production
studies which clearly show the strong pp final state interaction (FSI), the
cross section values obtained at COSY-11 and DISTO can be both described by a
fit with a four-body phase space including the proton-proton final state
interaction as well as with one-meson exchange calculations neglecting FSI
effects. Therefore, one might think about a compensation of the strong pp
interaction through a pK- FSI effect or an additional degree of freedom caused
by the four-body final state. In the latter case, strong FSI effects can be
expected at Q-values very close to the K+K- production threshold. Such a
motivation triggered -- in combination with the investigation of the
kaon-Antikaon interaction being relevant to the structure of the f0(980) --
further measurements at the excess energies Q=10 and Q=28 MeV at COSY-11.Comment: 5 pages, 4 figures, Presented at X. International Conference On

Threshold Hyperon Production at COSY-11
The Lambda, Sigma0 and Sigma+ hyperon production in NN collisions is studied
at the COSY - 11 installation in order to investigate the production mechanism
as well as to extract information about the Y-N interaction.Comment: 3 pages, 2 figure
General thoughts to the Kaon pair production in the threshold region
Simple--minded thoughts about the cross sections for the reactions
pp-->ppK+K- and pp-->ppK0K0 are presented, which certainly do not account for
the complex coupled channel problem but rather provide some ideas into the
mutual reaction dynamics.Comment: Talk given at 9th International Workshop on Meson Production,
Properties and Interaction, Cracow, Poland, 9-13 June 2006. 3 pages, 2
