- Description: This study explored and described the experiences of students with self-reported symptoms of anxiety and depression who participated in a mindfulness-based intervention. The study was conducted in collaboration with the Student Counselling Career and Development Centre (SCCDC) at the Nelson Mandela Metropolitan University (NMMU). The study utilised a qualitative research approach and nine participants were selected through purposive, non-probability sampling. The data were collected by means of semi-structured interviews and participants‟ brief written reflections of their individual experiences. Content analysis produced ten themes categorised according to the components of the biopsychosocial/spiritual (BPSS) model. The most prevalent theme identified, describing participants‟ experience of the mindfulness-based intervention, was an enhanced perception of emotional regulation. This finding confirmed the outcomes of previous studies that also found an increase in emotional regulation related to mindfulness-based interventions. Results also shed new light on the perceived personal changes participants experienced in relation to body awareness, increased attentional regulation, social interactions, and spiritual experiences. In addition, participants verbalised present moment awareness and an accepting non-judgmental attitude as central to the biopsychosocial/spiritual changes and benefits they experienced. Recommendations for further research include investigating the impact of mindfulness-based interventions on attentional control and social interactions.

- Description: Exchange rates are one of the most essential determinants of a country's economic performance in terms of level of trade. Since the exchange rate is one of the best indicators of competitiveness, this study sought to examine the behaviour of the rand against other emerging countries in the South African exchange market. The study explored the trends and estimated the forecasting accuracy of six currency markets using ARCH-family and Random walk models over the period 1994 to 2013.The six currency markets examined were the Rand/Dollar, Rand/Pound, Rand/Euro, Rand/Yen and Rand/Pula. The Rand exchange rates did exhibit the characteristics of volatility clustering and asymmetric effects suggesting volatility of the Rand. Exchange rates tend to rise when there is more bad news in the financial market than good news and positive shocks imply a higher next period conditional variance than negative shocks of the same sign.

- Description: This treatise investigates the implementation challenges of performance monitoring and evaluation in the O R Tambo District Municipality. The treatise comprises five chapters. The study is based on the assumption that O R Tambo District Municipality, like any other municipality in South Africa, particularly in the Eastern Cape, is confronted with the implementation challenges of performance monitoring and evaluation. ORTDM has a performance-management system that is not fully implemented, and needs to put into context its challenges, in order to appropriately make those interventions relevant to the situation. The fact that the performance- management system has not yet been cascaded to the lower level employees creates difficulties in performance monitoring and evaluation. There has been a deep concern that municipalities are underperforming, and yet with no visible steps being taken to improve the situation. If the O R Tambo District Municipality is attempting to achieve the objectives of the local government, as stated in the Constitution of the Republic of South Africa, 1996, it is then necessary to properly implement performance monitoring and evaluation, as mechanisms to accelerate service delivery. This has the potential to improve the quality of life of the citizens of O R Tambo District Municipality. This study provides the general background to the implementation challenges of performance monitoring and evaluation in the O R Tambo District Municipality. The challenges of performance monitoring and evaluation, the determinants of performance monitoring and evaluation, as well as the theories used in performance monitoring and evaluation will be addressed. The study presents the findings resulting from the analysis of the data provided by the respondents. Amongst the findings of the study there is a view that the O R Tambo District Municipality does not have monitoring and evaluation specialists who could ensure that performance is being periodically evaluated, in order to close policy gaps that might be in existence. Non-involvement or partial involvement of communities has the potential to cause stagnation, as people generally lack monitoring skills. Some of the recommendations include: the skills development of all the stakeholders, especially those with the mandate to deliver on behalf of government, that is, political office bearers, together with the technical support wing. Performance monitoring and evaluation under the proposed recommendations could be enhanced and positive changes could be realised.

The ecophysiology of Gelidium Pristoides (Turner) Kuetzing : towards commercial cultivation

- Description: The ecophysiology of the red alga Gelidium pristoides (Turner) Kuetzing was investigated in an effort to establish a technique for commercial cultivation. The seaweed is of commercial importance in South Africa where it is harvested from the intertidal zone rocky shores along the coast. It is dried and exported abroad for the extraction of agar. Yields and quality could be improved by cultivation in commercial systems. However, attempts at growing the seaweed in experimental systems have all ended in failure. This study aimed to describe the conditions in which the seaweed grows naturally; and investigate its physiological response to selected physical conditions in the laboratory in order to determine suitable conditions for mariculture. Ecological studies showed that G. pristoides grew above the spring low tide water level. The upper limit of the seaweed’s vertical distribution range, as well as its abundance, was largely dependent on wave exposure. The zone normally inhabited by G. pristoides was dominated by coralline turf in sheltered areas, while the abundance of G. pristoides increased towards more exposed rocky shore sites. The seaweed occurred among species such as Pattelid limpets and barnacles, but was usually the dominant macroalga in this zone, with coralline turf and encrusting algae being the only others. Physical conditions in the part of the intertidal zone inhabited by G. pristoides were highly variable. During low tide temperatures could vary by as much as 10°C within the three hours between tidal inundation of the seaweed population, while salinity varied by up to 9 ppt, and light intensity by as much as 800 μmol m-2 s-1. During these exposure periods the seaweed suffered up to 20% moisture loss. Laboratory experiments on the seaweed’s response to these conditions indicated that it was well adapted to such fluctuations. It had a broad salinity (20 and 40 ppt), and temperature tolerance range (18 to 24°C), with an o ptimum of temperature of 21°C for photosynthesis, while there was no difference in the photosynthetic rate of the alga within the 20 to 40 ppt salinity range. The alga had a low saturating irradiance (ca. 45 – 80 μmol m-2 s-1) equipping it well for photosynthesis in turbulent environments, with high light attenuation, but poorly to unattenuated light conditions. Exposure resulted in an initial increase in photosynthetic rate followed by a gradual decrease thereafter. pH drift experiments showed that low seawater pH, and associated increased carbon dioxide availability, resulted in an increase in photosynthetic rate. This response suggests that the seaweed has a high affinity for carbon dioxide, while the reduction in photosynthetic rate in response to bicarbonate use inhibition indicates that it also has the capacity for bicarbonate use. The high affinity of Gelidium pristoides for carbon dioxide as an inorganic carbon source appears to be the primary reason for the low abundance of the alga on sheltered rocky shore areas, and also explains the failure of the alga to grow in tank or open-water mariculture systems. Exposed rocky shores have experience heavy wave action, and the resultant aeration and mixing of nearshore waters increases the availability of carbon dioxide, which is considered a limiting resource. The absence of such mixing and aeration at sheltered site makes this less suitable habitat for G. pristoides. Periodic exposure also makes high levels of atmospheric carbon dioxide available from which the seaweed benefits. The traditional mariculture systems in which attempts have been made to cultivate the seaweed failed to satisfy either of the above conditions.
