The University of Johannesburg is a public university located in Johannesburg, South Africa. The University of Johannesburg came into existence on 1 January, 2005 as the result of a merger between the Rand Afrikaans University , the Technikon Witwatersrand and the Soweto and East Rand campuses of Vista University. Prior to the merger, the Daveyton and Soweto campuses of the former Vista University had been incorporated into RAU. As a result of the merger of Rand Afrikaans University , it is not uncommon for alumni to refer to the university incorrectly as RAU.The newly emerged institution is one of the largest comprehensive contact universities in South Africa, with nine faculties having more than 90 departments and an enrollment of approximately 48,000 students, spreading over four different campuses. The university is one of the largest residential universities in the Republic of South Africa. Wikipedia.

Health Policy and Planning | Year: 2015

In many low and middle income countries, attention to mental illness remains compartmentalized and consigned as a matter for specialist policy. Despite great advances in global mental health, mental health policy and practice dovetail only to a limited degree with social development efforts. They often lag behind broader approaches to health and development. This gap ignores the small but growing evidence that social development unavoidably impacts the mental health of those affected, and that this influence can be both positive and negative. This article examines the theoretical and practical challenges that need to be overcome for a more effective integration of social development and mental health policy. From a theoretical perspective, this article demonstrates compatibility between social development and mental health paradigms. In particular, the capability approach is shown to provide a strong framework for integrating mental health and development. Yet, capability-oriented critiques on 'happiness' have recently been applied to mental health with potentially detrimental outcomes. With regard to policy and practice, horizontal and vertical integration strategies are suggested. Horizontal strategies require stronger devolution of mental health care to the primary care level, more unified messages regarding mental health care provision and the gradual expansion of mental health packages of care. Vertical integration refers to the alignment of mental health with related policy domains (particularly the social, economic and political domains). Evidence from mental health research reinforces aspects of social development theory in a way that can have tangible implications on practice. First, it encourages a focus on avoiding exclusion of those affected by or at risk of mental illness. Secondly, it underscores the importance of the process of implementation as an integral component of successful policies. Finally, by retaining a focus on the individual, it seeks to avoid uneven approaches to development. © The Author 2014; all rights reserved. Source

Physical Review D - Particles, Fields, Gravitation and Cosmology | Year: 2013

Long duration gamma-ray bursts are powerful sources that can accelerate particles to ultrahigh energies. Acceleration of protons in the forward shock of the highly relativistic gamma-ray burst (GRB) blastwave allows PeV-EeV neutrino production by photopion interactions of ultrahigh energy protons with x-ray to optical photons of the GRB afterglow emission. Four different blastwave evolution scenarios are considered: adiabatic and fully radiative blastwaves in a constant density circumburst medium and in a wind environment with the particle density in the wind decreasing inversely proportional to the square of the radius from the center of the burst. The duration of the neutrino flux depends on the evolution of the blastwave and can last up to a day in the case of an adiabatic blastwave in a constant density medium. Neutrino fluxes from the three other blastwave evolution scenarios are also calculated. Diffuse neutrino fluxes calculated using the observed rate of long-duration GRBs are consistent with the recent IceCube upper limit on the prompt GRB neutrino flux below PeV. The diffuse neutrino flux needed to explain the two neutrino events at PeV energies recently detected by IceCube can partially come from the presented GRB blastwave diffuse fluxes. Future observations by IceCube and upcoming huge radio Askaryan experiments will be able to probe the flux models presented here or constrain the GRB blastwave properties. © 2013 American Physical Society.

The center of the Milky Way is a host to energetic phenomena across many electromagnetic wave bands and now possibly of high-energy neutrinos. We show that 5 out of 21 IceCube showerlike events, including a PeV event, likely originated from the Galactic Center region. A hard spectrum and flux inferred from these events are inconsistent with atmospheric neutrinos. The flux of these neutrinos is consistent with an extrapolation of the gamma-ray flux measured by Fermi-LAT from the inner Galactic region. This indicates a common hadronic origin of both, powered by supernovae. Three other showerlike events are spatially correlated with the Fermi bubbles, originating from the Galactic Center activity, within the uncertainty of reconstructing their arrival directions. The origin of the other neutrino events, including 7 tracklike events, is still elusive. © 2013 American Physical Society. Source

One of the central challenges of a maturing tourism destination is to ensure continuous innovation and improvement of tourism products to meet the demands of an increasingly competitive global tourism economy The purpose of this study is to analyse a critical aspect of the improvement of tourism product competitiveness in South Africa, the changing tourism accommodation sector and specifically of the hotel industry. During the study period 1990-2010 it is shown that the hotel industry was restructured in terms of enhanced quality standards, the introduction of new hotel products and driven by the imperatives of market segmentation. Geographically, the hotel sector became more concentrated upon four key urban tourism nodes and in certain cities the over-production of hotel accommodation is an emerging problem. © 2012 Elsevier Ltd.

This paper explores issues in the development of linkages between tourism and agriculture in developing world situations, a key challenge for pro-poor tourism. It contributes to the limited literature on food sourcing by tourism accommodation establishments by analysing tourism-agriculture linkages in the food supply chains of 80 luxury African safari lodges (ASLs) in rural South Africa. The results disclose important constraints on the establishment and strengthening of local linkages relating to lack of local production quality, consistency and volume required by ASLs. The role of transport, wholesale intermediaries and the rapid turnover of ASL procurement managers is also shown. Price was not a major factor, and contrary to some claims, most ASLs are not foreign owned or staffed by foreign chefs unused to local produce. Positive trends include rising South African food quality and variety, increasing niche market production and increasing tourist interest in fair trade and local foods. For policy intervention, the greatest significance is the failure of many local community initiatives, and the need for training, capacity building and support for local producers to enter the food supply chains. The key need, however, is to overcome poor communication and deep mistrust between food supply decision-makers and local producers. © 2012 Copyright Taylor and Francis Group, LLC. Source
