Critical managerial skills in the accommodation sector: The voice of the industry
Dynamic labour structures within the tourism industry require employees to be adept and prepared for industry demands to deliver quality products. In South Africa, the role of tertiary institutions is to equip future tourism employees with these abilities; however, employers feel that graduates cannot fulfil industry’s demand, which creates challenges for students and tertiary institutions. As such, this research aimed to determine the managerial skills required by the accommodation sector in South Africa.
The study’s findings reflect industry role players’ viewpoints regarding new graduates and their employability and may be utilised to improve current tourism management qualifications at tertiary education institutions
Group classification of the Sachs equations for a radiating axisymmetric, non-rotating, vacuum space-time
We carry out a Lie group analysis of the Sachs equations for a time-dependent
axisymmetric non-rotating space-time in which the Ricci tensor vanishes. These
equations, which are the first two members of the set of Newman-Penrose
equations, define the characteristic initial-value problem for the space-time.
We find a particular form for the initial data such that these equations admit
a Lie symmetry, and so defines a geometrically special class of such
spacetimes. These should additionally be of particular physical interest
because of this special geometric feature.Comment: 18 Pages. Submitted to Classical and Quantum Gravit
Compatibility of phenomenological dipole cross sections with the Balitsky-Kovchegov equation
Phenomenological models of the dipole cross section that enters in the
description of for instance deep inelastic scattering at very high energies
have had considerable success in describing the available small-x data in both
the saturation region and the so-called extended geometric scaling (EGS)
region. We investigate to what extent such models are compatible with the
numerical solutions of the Balitsky-Kovchegov (BK) equation which is expected
to describe the nonlinear evolution in x of the dipole cross section in these
momentum regions. We find that in the EGS region the BK equation yields results
that are qualitatively different from those of phenomenological studies. In
particular, geometric scaling around the saturation scale is only obtained at
asymptotic rapidities. We find that in this limit, the anomalous dimension
\gamma(r,x) of phenomenological models approaches a limiting function that is
universal for a large range of initial conditions. At the saturation scale,
this function equals approximately 0.44, in contrast to the value 0.628
commonly used in the models. We further investigate the dependence of these
results on the starting distribution, the small-r limit of the anomalous
dimension for fixed rapidities and the x-dependence of the saturation scale.Comment: 14 pages, 8 figures. Extensive revisions, several new results, plots,

Tuberous sclerosis complex in the Western Cape, South Africa: The clinical presentation features
Tuberous sclerosis complex (TSC) is a genetic neurocutaneous condition, which affects multiple organ systems. This study aimed to determine the presenting features of children with TSC in Cape Town, South Africa. A cross-sectional study was conducted at a TSC clinic, and clinical features at presentation were prospectively collected. Thirty-nine children (23 boys; median age 10 (range 1 - 26) years; median diagnosis age 16 (0 - 153) months) were recruited. Twenty-one (54%) children presented with focal seizures. Seven (18%) children had epileptic spasms. Skin manifestations led to a diagnosis in 13 (33%) and neuroimaging in 22 (56%) children. Antenatal screening detected cardiac rhabdomyomas in 3 children. One child had a positive family history. In the paediatric service, TSC diagnosis usually followed neuroimaging, whereas at the neurology service skin manifestations indicated TSC. In conclusion, most children with TSC presented as emergency cases with seizures. Health practitioner awareness of the common TSC clinical signs was lacking, with the diagnosis often delayed
Examining the use of telehealth in community nursing: identifying the factors affecting frontline staff acceptance and telehealth adoption
Aims: To examine frontline staff acceptance of telehealth and identify barriers to and enablers of successful adoption of remote monitoring for patients with Chronic Obstructive Pulmonary Disease and Chronic Heart Failure. Background: The use of telehealth in the UK has not developed at the pace and scale anticipated by policy. Many existing studies report frontline staff acceptance as a key barrier, however data are limited and there is little evidence of the adoption of telehealth in routine practice. Design: Case studies of four community health services in England that use telehealth to monitor patients with Chronic Obstructive Pulmonary Disease and Chronic Heart Failure. Methods: Thematic analysis of qualitative interviews with 84 nursing and other frontline staff; and 21 managers and key stakeholders; data collected May 2012-June 2013. Findings: Staff attitudes ranged from resistance to enthusiasm, with varied opinions about the motives for investing in telehealth and the potential impact on nursing roles. Having reliable and flexible technology and dedicated resources for telehealth work were identified as essential in helping to overcome early barriers to acceptance, along with appropriate staff training and a partnership approach to implementation. Early successes were also important, encouraging staff to use telehealth and facilitating clinical learning and increased adoption. Conclusions: The mainstreaming of telehealth hinges on clinical 'buy-in'. Where barriers to successful implementation exist, clinicians can lose faith in using technology to perform tasks traditionally delivered in person. Addressing barriers is therefore crucial if clinicians are to adopt telehealth into routine practice
Risk management in higher education: An open distance learning perspective
This article contributes to the continuing scholarly discourse on risk and risk management within the context of higher education institutions by reporting on a qualitative assessment of the appropriateness of the risk management framework of a selected open distance learning institution. The assessment is based on a single instrumental case study of an open distance learning institution. The assessment was undertaken by conducting a qualitative content analysis of the institution’s enterprise risk management framework document. For the purpose of this analysis, two reading strategies were followed, namely the reproductive (literal) and hermeneutic reading strategies. This article’s unique contribution to the scholarly discourse is to apply a conceptual framework derived from the work by Tufano (2011) providing trustworthy evidence that the critique by Leitch’s (2010) on the ISO 31000:2009 standard does not necessarily have an empirical sound foundation. The research has indicated that an enterprise risk management framework meeting the ISO 31000:2009 standard, is not only appropriate for a risk imbedded
open distance higher education institution such as the selected institution, but has the potential to contribute signifi cantly to the enhancement of the institution’s mission, strategic goals and objectives within an astringent national regulatory and funding context and an ever-changing international higher education landscape.Public Administration and Managemen
Is there a reentrant glass in binary mixtures?
By employing computer simulations for a model binary mixture, we show that a
reentrant glass transition upon adding a second component only occurs if the
ratio of the short-time mobilities between the glass-forming component
and the additive is sufficiently small. For , there is no
reentrant glass, even if the size asymmetry between the two components is
large, in accordance with two-component mode coupling theory. For , on the other hand, the reentrant glass is observed and reproduced only by
an effective one-component mode coupling theory.Comment: 4 pages, 3 figure
Rosenfeld functional for non-additive hard spheres
The fundamental measure density functional theory for hard spheres is
generalized to binary mixtures of arbitrary positive and moderate negative
non-additivity between unlike components. In bulk the theory predicts
fluid-fluid phase separation into phases with different chemical compositions.
The location of the accompanying critical point agrees well with previous
results from simulations over a broad range of non-additivities and both for
symmetric and highly asymmetric size ratios. Results for partial pair
correlation functions show good agreement with simulation data.Comment: 8 pages with 4 figure
