ABSTRACT As treatment and health care related to HIV/AIDS improve, infected partners now have a chance to live longer than before, thus, HIV concordancy and discordancy have become quite common among partners in union. The infected partners, however, increasingly face emotional and psychosocial challenges associated with HIV infection. These challenges expose them to the risk of developing depression symptoms, declined intimacy and dysfunctional relationships, with considerable variations am...
ABSTRACT Globally it has been established that human resource (HR) practices are associated with human resource (HR) performance. The application of the HR practices appears to be effective when applied in the decentralized context where employees‟ accountability is effectively enhanced. It is in the same perspective that during the 1990s Tanzania adopted decentralization by devolution in which the HR practices are applied at a facility level to enhance the HR performance. Nevertheless, li...
ABSTRACT Ethics as an aspect of axiology has always existed strictly as a human affair. This had given rise to the conclusion that human-centred ethics, in its conception and articulation is insufficient in the face of the present day environmental problem; since humans neither consider the natural world nor its wild living beings as entity worthy of moral consideration. With the three main components of Taylor’s ethics, namely: the beliefsystem, the attitude of respect for nature and the ...
ABSTRACT This dissertation offers a comprehensive account of the origin, nature and development of theatre under the auspices of the Arts Association as a cultural activity in South West Africa as it was called until 1968. In 1947 a branch of the South African Association of Arts, a Fine Arts organisation in South Africa was established in Windhoek, South West Africa. The association organised and developed the Performing Arts in addition to the Visual Arts. The Arts Association saw theatre ...
ABSTRACT The distribution of malaria in Namibia is mainly confined to the northern parts of Namibia. Although the malaria vectors were presumed to be Anopheles arabiensis, a member of the Anopheles gambiae group of morphologically similar species, no scientific study had been undertaken to identify the species in Namibia. Given the variable behaviour of this species, in an area where the mainstay for vector control has been indoor residual house spraying (IRS) with 75% DDT wettable powder si...
ABSTRACT Namibian health care workers (health care workers) are affected in providing quality health care services to people who are living with HIV / AIDS (PLWHA) if they do not have the necessary knowledge, as well as adequate interpersonal communication and counselling skills. In a health care facility set-up, all patients either come from the community or are referred from the wards or other departments by health care workers. The health care worker as a (sender) conveys information (mes...
Abstract The Faint Low-Frequency Radio Universe in Continuum: Exploitation of the Pre-SKA Deepest Survey This thesis presents a thorough and significant work on the properties of radio sources as derived from deep 610-MHz GMRT data and ancillary multi-wavelength data. The faint radio sources at 610-MHz are found out to distances such that the objects are seen as they were when the universe was less than half its current age. These data provide a first look at the faint radio sky at sensitivit...
Abstract Building on current knowledge, the primary aim of the present study was to assess psycho-social correlates of Masculine Gender Role Conflict (MGRC) among homosexual men and to posit and test a model by which the variables (psychological well-being, gay identity development and attitudes towards psychological help seeking behaviour) are related to MGRC. Guided by the Male gender role conflict theory, survey and interviews were used to collect data from 175 homosexual men. The data ana...
Abstract Obligate brood parasites lay their eggs in the nests of other species, foisting the costs of parental care onto the host parents. The success of the parasite and host are then at odds, with both parties evolving defences and countermeasures in an evolutionary arms race. This reciprocal influence of acting upon both species’ evolution — a process known as coevolution — has forged the natural world around us. Avian brood parasites and their hosts are now model systems for studyin...
Abstract The development of enhanced selectivity of a host towards (aromatic) isomers continues to be an important feature in supramolecular studies. In this thesis, several nickel Werner complexes have been synthesised and used as crystallographic hosts with inclusions of aromatic isomers, polycyclic aromatic hydrocarbons, alcohols or ketones. Thermogravimetric methods were used to confirm the composition of the host-guest complexes and were employed to analyse their thermal behaviour. Struc...
SHORT ABSTRAC Over the past decade there has been global concern about the bycatch of seabirds, turtles and sharks in fishing operations, in particular longline and trawl fisheries, which have been widely held responsible for their declining populations and threatened conservation status. This thesis addresses the issue of bycatch in a holistic manner, taking into account that species, whether they be target or non-target, do not exist in isolation from each other and their environment. South...
ABSTRACT Nel, J.L. 2008. Enhancing the conservation of freshwater biodiversity through improved freshwater conservation planning techniques. PhD thesis, University of Cape Town. Freshwater ecosystems and biota are among the most endangered in the world. This current situation is even more disturbing when future threats of escalating human demand and global climate change are considered. Urgent measures are therefore needed to conserve freshwater ecosystems and sustain the services they provid...
Abstract This thesis uses phylogenetic and comparative data to test an hypothesis of adaptive radiation in the Cape grass genus Ehrharta Thunb. sensu stricto. Morphological data and sequence data from two noncoding regions of DNA (lTS1 and trnL-F) are used to produce a phylogenetic hypothesis for the tribe Ehrharteae. Combined analysis of these data sets resolves four principal clades that approximate the genera Ehrharta s. s., Micro/aena, Tetrarrhena and Zotovia and this result thus supports...
ABSTRACT Most researchers agree that work placement has a positive influence on students’ employability. Despite this consensus, there has been conflicting research on the factors that contribute to this influence. Moreover, the social mechanisms through which this outcome is realised have not been well understood. To address these shortcomings, this study explores how mechanical engineering students’ work placement experiences facilitate or hinder the growth of their occupational compete...
1.1Background and Motivation Impact evaluation studies are designed to get at the impact of a policy or treatment. The aim is often to assess the viability or success of an intervention. These studies are also useful in cost-benefit analyses for gauging the size of the benefit attributable to an intervention. It is therefore important for an estimated treatment effect to be as free from bias as possible. The object of interest is often the Average Treatment Effect on the Treated (ATT), which ...
