    The semi-arid conditions in savanna landscapes ensure that ephemeral drainage dominates the hydrological network in these dryland systems. Quantification of their hydrological processes is important to inform ecosystem understanding and future conservation efforts under a changing climate, and to provide guidance for restoration. By combining in situ hydrometric observations, hydrochemistry, remote sensing and a soil water balance model, we characterise the groundwater–surface water interactions in ephemeral low-order catchments of the granitoid regions of the southern Kruger National Park (KNP). Streams at the lowest orders are augmented by lateral interflows from the catena, although the second-and third-order stream reaches are conduits for groundwater recharge to the fractured rock aquifer; the soils of the crests and foot-slopes also show preferential flow, and are truly recharge soils, whilst the duplex soils of the midslopes clearly show their responsive nature to a low soil moisture deficit in the shallow horizons. Actual evaporation (aET) differed between catena elements with surprisingly little variation at third-order hillslopes, with the greatest overall aET at the first order. Meanwhile, soil water balances demonstrated a significant variation in storage of the riparian zones as a result of interflow from upslope and aET losses. Furthermore, data support broader-scale observations that groundwater recharge through the vadose zone to the fractured rock aquifer is dependent upon threshold antecedent precipitation conditions. Moderate precipitation events (5 mm/day – 35 mm/day) over a 2–3 week period initiate groundwater responses with a 2–3 month lag, whilst intense precipitation events (>100 mm/day) are expressed within 2–3 weeks

    Abstract: The employer–employee relationship is becoming increasingly strained, evidenced by the increase in cases referred to the Commission for Conciliation, Mediation and Arbitration. These disputes are presumed to be a consequence of breach of the psychological contract of undelivered expectations or obligations. There seems to be a need to improve the management of employer–employee relationships. Research purpose: The purpose of this investigation was to identify inducements and obligations made known by organisations on their websites. Motivation for the study: Clarity of inducements and expectations may provide a foundation to proactively improve the employer–employee relationship..

    M.Phil. (Employment Relations)Abstract: Orientation: The employer-employee relationship is becoming increasingly strained, as evidenced through the increase in average cases referred to the Council for Conciliation, Mediation and Arbitration. This is presumed to be a consequence of breach of the psychological contract in terms of expectations or obligations not delivered upon. A proactive means of identifying the content of the psychological contract may improve how the employer-employee relationship is managed and maintained. Research purpose: The aim of this research is to explore which inducements and obligations are made known by organisations. Motivation for the study: Exploring these inducements and expectations may yield an understanding as to the foundation and development of the employer-employee relationship. This in turn could lead to better and proactive management of the employer-employee relationship. Research design, approach and method: A content analysis design was followed to identify inducements and expectations on companies’ websites. A codebook based on content associated with the psychological contract was constructed and applied to websites listed in the 2015 Business Times Top 100 companies of past five years. Main findings: Comparisons between different sectors (Manufacturing, Wholesale and retail, Financial services) yielded significant differences between Organisational policies and Career development inducements. Comparisons on the presence of a career section revealed that those companies with a career section convey more inducements and expectations than companies without a career section. Practical/managerial implications: By applying the measure through a content analysis, companies can identify which inducements and expectations are conveyed through the websites as this informs the psychological contract..

    The failure of the Middle East peace process and structures for conflict

    Thesis (MA)--Stellenbosch University, 2002.ENGLISH ABSTRACT: This study focuses on the role of political elites in addressing the problem of why a durable peace has eluded Israeli Palestine. A theoretical background study was made on the articulation of identity within a civilization. This established identity formation as a political process. To see how the manipulation of the structure within which identity formation processes take place, six critical indicators were identified. These are: Manufacturing conditions of underdevelopment; Un-integrated social and political systems, and distributive injustice; Fostering cleavages, stereotypical images and political symbolism; Placing issues under the 'sign of security'; The production of insecurity through the manipulation of identity formation processes; and Monopolising the conflict resolution process. Political elite creation and perpetuation of structures for conflict shows an inherent inability to bring about a lasting peace in a protracted social conflict for conflict has become the source, rather than the outcome of policy formation. As a result this thesis calls for a more inclusive approach to conflict resolution, one that goes beyond the processes of arbitration, mediation, negotiation and facilitation, to include conciliation at grass roots level between civilizations, sincerely exploring the underlying emotional legacies of fear, hatred, sorrow and mistrust.AFRIKAANSE OPSOMMING: Hierdie studie fokus op die rol gespeel deur politieke elites in die voortslepende vraagstuk rondom vrede in Israel/Palestina. 'n Teoretiese agtergrondstudie is onderneem om die uitdrukking van 'n samelewing oftewel volksidentiteit te ondersoek. Die studie het laat blyk dat identiteitsformulering 'n politieke proses is. Om waar te neem hoe die manipulasie van die struktuur waarbinne identiteitsformulering plaasvind, is ses kritiese indikators geïdentifiseer, te wete: die skepping van toestande vir onderontwikkeling; ongeïntegreerde sosiale en politieke sisteme en ongelyke verdeling van welvaart; doelbewuste voortsetting van etniese verskille, stereotipering en politieke simbolisme; plasing van kwessies onder die vaandel van "sekuriteit"; die produksie van "onsekerheid" deur die manipulasie van identiteitsformulering prosesse; en die manipulasie van konflik resolusie prosedures. Skepping en doelbewuste voortsetting van strukture vir konflik deur politieke elites dui op 'n onvermoë om langdurige vrede in 'n 'uitgerekte sosiale konflik' te bewerkstellig. Konflik het die oorsprong, eerder as die uitkoms van beleid geword. As gevolg van hierdie feite doen die tesis 'n beroep dat konflik resolusie as dissipline 'n meer inklusiewe benadering volg. Die resolusie prosesse van mediasie, arbitrasie, fasilitering en onderhandeling is opsigself nie genoeg nie en behoort vergesel te word deur die proses van konsiliasie op grondvlak tussen samelewings. Hierdie proses moet deel vorm van 'n opregtheid om mense se vrese, haat, seer en wantroue met ootmoed aan te hoor

    Disaster risk reduction initiatives in South Africa

    The field of disaster management in South Africa has developed dramatically over the past seven years. The paradigm shift from civil protection to disaster risk management brought with it the realisation that the management of disaster risk is paramount to reducing successfully the vulnerability of these communities most at risk. The resilience and coping mechanisms of communities affected by disasters have demonstrated the importance of local and traditional knowledge in the reduction of risk and the effects of hazards. This article aims to explore various initiatives for disaster risk reduction in South Africa undertaken by government departments and non-governmental organisations from 1994 to 2003. It describes the various methods and systems employed to reduce risk and vulnerability. A case study of the February 2000 floods in the Limpopo province of South Africa provides insight into local coping mechanisms and indigenous methods of risk reduction.

    Objective: This study was conducted to determine the prevalence of hazardous, harmful and dependent drinking among hostel-dwelling students on the main campus of the University of the Free State (UFS), and the influence of sex and academic year on the habit.Method: A quarter of all hostel-dwelling students of UFS were selected by systematic random sampling. Willing participants completed a questionnaire comprising a demographic section and the Alcohol Use Disorders Identification Test (AUDIT).Results: Of the 339 participants with total AUDIT scores, 15.6% exhibited hazardous drinking, 4.1% harmful drinking and 5.6% alcohol dependence. Male students had a statistically significant higher prevalence (32.8%) of hazardous, harmful or dependent drinking than female students (18.9%). Women, however, are biologically more vulnerable to the ill effects of alcohol due to altered pharmacokinetics and pharmacodynamics of alcohol. In addition, intoxicated women suffer more biological and social risks. When the cut-off point for hazardous drinking was adapted to account for the increased biological vulnerability of women, the difference between female and male participants was no longer significant. First year male students were less likely to engage in unsafe drinking than senior students. Female students in the alcohol dependent category showed an increasing trend over advancing academic year.Conclusions: Follow-up studies are needed to confirm whether a significant difference in hazardous drinking of first year male students compared to seniors reflects the influence of university policy or merely precedes drinking acculturation
