Feeding and spatial ecology of brown hyaena (hyaena brunnea) in the presence of a vulture restaurant on Mogale’s Gate Biodiversity Centre, Gauteng province, South Africa
No full textText in English, abstracts in English, Afrikaans and Northern SothoInitial studies of brown hyaena occurred mainly in relatively large and arid systems, such as in the Namib Desert, the Kalahari region of southern Africa and savanna regions of Botswana and northern South Africa. In recent years studies on this species have focused on smaller areas, and in different habitats and land use types. My study investigated the feeding and spatial ecology of brown hyaena in the presence of a long-standing supplementary feeding site (vulture restaurant) on the Mogale's Gate Biodiversity Centre, a small (3060 ha) protected area in the Gauteng province of South Africa. Vulture restaurants have, for decades, been used globally to facilitate conservation by increasing survival and reproduction in local vulture populations. As little is known about the potential impact of vulture restaurants on other scavengers the main objective of my study was to ascertain how the presence of a long-standing vulture restaurant influences aspects of brown hyaena feeding ecology, home range and population estimates. Scat analysis was used to determine the seasonal diet of brown hyaena. Brown hyaena have access to a regular supply of carrion at the vulture restaurant which during my study contributed 43% to their overall diet. The remaining 28% was made up of smaller prey items, and 9% plant material. Population data were collected by camera traps placed across the property over a 15-month period, in which time 5 independent capture-recapture surveys were done. In order to test for population closure and to select the best models for capture probability, the Program CAPTURE was used. The program DENSITY 5.0. was used to run non-spatial capture-recapture analyses. Over the 15-month survey period abundance estimates ranged from 4 to 6 individuals per three-month capture period, resulting in density estimates of 13 to 20 individuals per 100 km2. The density estimates obtained from my study are higher than those calculated for brown hyaenas in arid areas, but similar to those of small reserves in the Eastern Cape province of South Africa. Home range estimates were calculated by using satellite collar data in QGIS V2.18 and generated using the adehabitatHR package (version 0.4.1.9) (Calenge 2006) in program R 3.5.0 (R Core Team 2018). Two methods for home range estimates were used and compared - Kernel Utilisation Distribution and Minimum Convex Polygons. Two of the three collared, hyaena were found to make regular use of the vulture restaurant and their home ranges were smaller than that reported elsewhere. The relatively small home ranges may suggest that there are sufficient resources available within Mogale's Gate for these brown hyaenas. The results from my study indicate that food resources provided by a permanent vulture restaurant influences the diet, population density, and home range size of individual brown hyaenas. It is suggested that in an area such as the Magaliesberg Biosphere Reserve, where large predators such as lion, cheetah and wild dog no longer occur, the vulture restaurants in the region act as an alternative food source for brown hyaenas, maintaining potentially viable populations and thus acting as a buffer to local extinction for this species.Voorheen is studies oor die bruin hiëna meestal gedoen in taamlik uitgestrekte en droë stelsels soos die Namibwoestyn, die Kalahari in suidelike Afrika en die savannas van Botswana en die noorde van Suid-Afrika. In die laaste jare is studies oor hierdie hiënaspesie egter in kleiner gebiede, ander habitatte en gebiede met ander grondgebruike gedoen. Ek het die voedingsgewoontes en ruimtelike ekologie van die bruin hiëna in ʼn klein, beskermde gebied (3 060 ha), genaamd die Mogale's Gate Biodiversity Centre, in die Gauteng provinsie in Suid-Afrika bestudeer. Na aanleiding van ʼn aanvanklike studie oor die teenwoordigheid van spesies wat ʼn aanvullende voedselbron gebruik, was die doel van hierdie studie om vas te stel of die langdurige teenwoordigheid van ʼn voerplek vir aasvoëls op die eiendom enigsins ʼn uitwerking op bruin hiënas se voedingsekologie, tuisveld en geskatte bevolking het. Die seisoenale dieet van bruin hiënas is aan die hand van ʼn SCAT-ontleding bepaal. Die aas wat hulle gereeld by die aasvoëlvoerplek kry, het in die studie tydperk 47% van die bruin hiënas se dieet uitgemaak. Soogdier prooi, plant materiaal en voël reste het die oorblywende 53% uitgemaak. Die bevolkings data is oor 15 maande versamel met behulp van kameras wat oral op die eiendom versteek is. In hierdie tydperk is vyf onafhanklike vang-hervang opnames gedoen. Om vir bevolkings digtheid te toets en die mees geskikte modelle vir vangswaarskynlikheid te kies, is die CAPTURE-program gebruik. Die nieruimtelike vang-hervang ontleding is met behulp van die DENSITY 5.0.-program gedoen. In die 15-maande tydperk is vier tot ses individue elke drie maande gevang. Gevolglik is die bevolkings digtheid op 13 tot 20 individue per 100 km2 geskat. Ofskoon die bevolkingsdigtheidskattings in hierdie studie hoër is as dié vir bruin hiënas in droë gebiede, stem dit ooreen met dié van bruin hiënas in klein reservate in die Oos-Kaap provinsie van Suid-Afrika. Die oppervlakte van tuisvelde is met satelliet halsband data in QGIS V2.18 geskat, en met die adehabitatHR-pakket (0.4.1.9-weergawe) (Calenge 2006) in die program R 3.5.0 (R Core Team 2018) gegenereer. Kernel Utilisation Distribution en Minimum Convex Polygons, die twee metodes waarvolgens die oppervlakte van tuisvelde geskat is, is met mekaar vergelyk. Twee van die drie hiënas met halsbande het die aasvoëlvoerplek gereeld besoek, en hulle tuisvelde was kleiner as dié wat elders opgemerk is. Hulle betreklik klein tuisvelde kan beteken dat daar by Mogale’s Gate genoegsame voedsel vir hierdie bruin hiënas is. Ek het in hierdie studie gevind dat die voedsel by die permanente aasvoël voerplek die dieet, bevolkings digtheid en grootte van sommige bruin hiënas se tuisveld beïnvloed. Daar word aanbeveel dat die aasvoël voerplekke in gebiede soos die Magaliesberg-biosfeerreservaat, waar groot predatore soos leeus, jagluiperds en wildehonde nie langer voorkom nie, as alternatiewe voedselbron vir lewensvatbare bevolkings van bruin hiënas aangewend word om hierdie spesie van uitsterwing te red.Dinyakišišo tša peleng ka ga phiri ye tsooto di dirilwe kudu ka mafelong a magolo a komelelo, a go swana le ka Leganateng la Namib, ka dileteng tša ka Kalahari tša borwa bja Afrika le ka mafelong a mehlare ye mentši a ka Botswana le ka leboa la Afrika Borwa.

Investigating the relationship between career adaptability, career anchors and organizational commitment
No full textThe aim of this study was to (1) to investigate the relationship between career
adaptability (measured by the Career Adaptability Scale), career anchors (measured
by the Career Orientations Inventory) and organisational commitment (measured by
the Organisational Commitment Questionnaire); and (2) determine whether employees
from different groups, namely age, employment level, gender and race, differ
significantly in their levels of career adaptability, career anchors and organisational
commitment. A quantitative survey was conducted through simple random sampling
on a sample (N = 158) of employees in the Provincial Treasury in KwaZulu-Natal (a
public sector organisation).
The research findings indicated that a partial relationship exists between career
adaptability and career anchors with organisational commitment. However, career
adaptability has a significant relationship. The study therefore concluded that career
adaptability, career anchors and organisational commitment are partially related. A
further finding was that the variables of age, employment level, gender and race
partially differ for career adaptability, career anchors and organisational commitment.
It is recommended that strategies/interventions for employee retention practices
should be enhanced by taking cognisance of the research findings relating to the three
variables of career adaptability, career anchors and organisational commitment. In
conclusion, recommendations were formulated for the field of industrial and
organisational psychology and possible further research on this topic.M. Com. (Industrial and Organizational Psychology)Industrial and Organisational Psycholog
A critical review of the implementation of the security threat assessment by a selection of government department in Gauteng
No full textThe imperative for protecting critical national infrastructure has engendered development of the Security Threat Assessment Framework that is implemented by the South African government under the guidance of the State Security Agency (SSA). The objective of the STRA Security Threat Assessment Framework is to detect any weaknesses in existing security measures, and to recommend strategies to evaluate ameliorative improvements in those identified weaknesses. The aim of the study is to critically review the implementation of the security threat assessment by a selection of government Department in Gauteng.
The study has adopted a qualitative research design approach due to its constructivist-interpretivist inspiration and reliance on participant-centred mode of acquiring the study’s pertinent primary data through document analysis, semi-structured in-depth interviews with the primary participants, and observations with secondary participants. The study population comprised of security managers, vetting managers, cybercrime managers, information security managers, physical security managers, and professionals in the security environment. Additionally, the target population and sample size consisted of 47 participants from various spheres of the security sector locally. These participants were selected through the purposive and simple random sampling strategies respectively.
Some of the study’s critical findings show that there was general awareness and knowledgeability concerning the appointment processes and roles of security managers and security committees. The role of technology was viewed as beneficial. As such, the security of sensitive information necessitated that personnel working in high-risk environments as well as personnel in charge of information technology systems should be subjected to security procedures. These procedures include declaration of secrecy, security profile checks of each user, limiting access to top secret to individuals nearing retirement or exiting the system; as well as backup of the sensitive information in case it may be tampered with.D.

The role and functioning of marketing of public schools in Gauteng Province
Get PDFSchools, specifically in Gauteng, have started to feel the pressure to compete with other schools for prospective learners’ and parents’ attention to enrol at their individual schools. The explicit marketing of the schools has become a must for every school wanting to attract quality learners to their schools. The time when schools could depend on the learners from the immediate community to attend the school geographically closest to them has long gone. Parents and learners alike are scouting for a school that will best fit their needs.
This study focused on secondary schools in the Tshwane South District 4 that already have a marketing team in place managing and focusing on marketing activities at their schools. This study attempts to give guidelines to individuals at the head of the marketing events and activities at their school to improve their attempts based on business-related marketing models and tools.
A qualitative research method was followed in which five schools participated and eight individuals were interviewed using semi-structured interviews. The questions were prepared based on the four main research objectives: 1) to explain how the nature and importance of marketing impact on the management of a public school; 2) to describe how the roles of the school management team (SMT), school governing body (SGB), educators, and the community are understood in the marketing of a public school; 3) to identify what the necessary management actions are that schools can follow to enhance their positioning in a changing marketing environment; and 4) to specify the core issues that form part of a comprehensive and coherent marketing strategy for schools.
Through the research, it was established that marketing plays a vital role in the successful functioning of a school. There are various role players involved in the successful execution of a strategic marketing plan for each school, especially the leadership of a school. The leadership, in turn, must be supported by various other groups of people including the staff at the school, the learners, and the wider community of the school. The actions of the leaders in the marketing of the school must be focused on satisfying the wants and needs of the learners and parents. It is the learners and parents that become ambassadors for the school outside of the direct school community.
It is recommended, as found in this study, that all schools must have a dedicated appointed marketer at the school. Together with the SMT and SGB, a concrete strategic marketing plan must be developed to ensure that the vision, mission, and culture of the school are captured and reflected in all marketing activities and events. The focus must be on the learners and the parents to enable them to want to be part of the school environment and, in turn, invest their knowledge, skills, and resources back into the development of the school.M.

An exploration of the operational functioning of the South African Police Service Crime Information Management and Analysis Centre
Get PDFAbstracts in English, Afrikaans and TsongaCrime is one of the most topical issues in contemporary society, and South Africa
is not immune in this regard. Police have for ages developed strategies and
techniques to address crime. However, these strategies were unsuccessful in
addressing or at least, reducing crime. Notwithstanding that crime analysis has
been introduced to police organisations, there seems to be a challenge that the
police organisations fail to use crime analysis and its products in the fight against
crime. Realisation of such failure prompted the researcher to conduct this study with
the aim of exploring, describing and analysing the operational station-level
functioning of the Crime Information Management and Analysis Centre (CIMAC)
within the South African Police Service (SAPS) organisational system and
structures in order to identify the shortcomings thereof; and subsequently
developing a framework of recommendations to enhance the efficient functioning of
CIMAC.
The current study has adopted the pure qualitative research approach, which
resonates with the anti-positivist philosophical paradigm and case study designs.
Accordingly, data was collected sequentially through an extensive review of
literature and followed with the semi-structured interviews. The review of literature
was broadened beyond the local context and included a comparative study with
sampled international police agencies. Both national and international literature
were reviewed to obtain information and gain an in-depth understanding regarding
crime information management and analysis and the role of crime analysts.
During the research, extensive interviews were conducted with SAPS CIMAC
members and CIMAC clients at station level, as well as members of the Crime Registrar at the provincial and national levels. International participants were also
interviewed in this study to obtain international perspectives of the problem being
researched. Various objectives were fulfilled in this study:
To explore and describe the meaning of crime information analysis within the
SAPS;
To explore and describe the use of crime information analysis within the SAPS;
To explore and describe the role and functioning of the Crime Information
Management and Analysis Centre (CIMAC);
To explore and describe the use of crime information management and analysis
within the SAPS;
To determine the role of CIMAC in crime reduction and prevention;
To explore and describe international practices relating to the use of crime
information analysis; and
To develop practical guidelines, procedures and recommendations for the
successful use of CIMACs within the SAPS.
The researcher is of the opinion that this study and its results provide the framework
and a regime of scientifically informed propositions and recommendations that could
be applied by the relevant SAPS policymakers to improve CIMAC’s operational
functioning on the basis of a credible and reliable research-based investigation.
Finally, this study also contributes to the foundation of knowledge, with regard to
the operational functioning of CIMAC at the police station level.Misdaad is een van die mees aktuele aangeleenthede in ons eietydse samelewing
en Suid-Afrika is allermins immuun teen misdaad. Die polisie het oor die jare heen
strategieë en tegnieke ontwikkel om misdaad teë te werk. Hierdie strategieë is egter
onsuksesvol om misdaad aan te pak, of dan minstens te verminder. Ten spyte van
die instel van misdaadontleding by polisie-organisasies blyk dit dat dit ’n uitdaging
vir polisie-organisasies is om misdaadontleding en sy produkte in die stryd teen
misdaad te gebruik. Die besef van hierdie mislukking het die navorser genoop om
hierdie studie te doen ten einde die operasionele stasievlakfunksionering van die
Misdaadinligtingsbestuur- en Ontledingsentrum (Crime Information Management
and Analysis Centre – CIMAC) in die Suid-Afrikaanse Polisiediens (SAPD) se
organisatoriese stelsel en strukture te ondersoek, te beskryf en te ontleed om die
tekortkominge daarvan te identifiseer; en daarna ’n raamwerk met aanbevelings te
ontwikkel om die doeltreffende funksionering van CIMAC te verbeter.
Hierdie studie het die suiwer kwalitatiewe benadering gebruik, wat aanklank vind by
die anti-positivistiese filosofiese paradigma en gevallestudie-ontwerpe. Die data is
derhalwe sekwensieel deur middel van ’n uitgebreide hersiening van literatuur, met
behulp van halfgestruktureerde onderhoude, ingesamel. Die oorsig van die
literatuur is uitgebrei om meer as net die plaaslike konteks te omvat en het ’n
vergelykende studie met bestudeerde internasionale polisie-agentskappe ingesluit.
Nasionale sowel as internasionale literatuur is hersien om inligting te bekom en
diepgaande begrip oor misdaadinligtingsbestuur en -ontleding en die rol van
misdaadontleders te verseker.
Tydens die navorsing is omvattende onderhoude met SAPD-CIMAC-lede en
CIMAC-klante op stasievlak, asook met lede van die Misdaadregistrateur op
provisiale en nasionale vlak, gevoer. Onderhoude is ook in hierdie studie met
internasionale deelnemers gevoer om internasionale perspektiewe van die
probleem wat nagevors is, te bekom. Verskeie oogmerke is met hierdie studie
bereik:
Om die betekenis van misdaadinligtingsontleding in die SAPD te ondersoek en
te beskryf;
Om die gebruik van misdaadinligtingsontleding in die SAPD te ondersoek en te
beskryf;
Om die rol en funksionering van die Misdaadinligtingsbestuur- en
Ontledingsentrum (CIMAC) te ondersoek en te beskryf;
Om die gebruik van misdaadinligtingsbestuur en -ontleding in die SAPD te
ondersoek en te beskryf;
Om die rol van CIMAC by misdaadvermindering en -voorkoming vas te stel;
Om internasionale praktyke wat verband hou met die gebruik van
misdaadinligtingsontleding te ondersoek en te beskryf; en
Om praktiese riglyne, prosedures en aanbevelings vir die suksesvolle gebruik
van CIMACs in die SAPD te ontwikkel.
Die navorser is van mening dat hierdie studie en sy resultate die raamwerk en ’n
regime van wetenskaplik-ingeligte voorstelle en aanbevelings daarstel wat
toegepas kan word by die relevante SAPD-beleidmakers om CIMAC se
operasionele funksionering op grond van ’n geloofwaardige en betroubare
navorsingsgebaseerde ondersoek te verbeter. Ten slotte het hierdie studie ook
bygedra tot die kennisfondasie wat betref die operasionele funksionering van
CIMAC op polisiestasievlak.Vhutshinyi ndi tshiṅwe tsha fhungo la ndeme kha tshitshavha tsha zwino, nahone

The novice-teacher in context : the exposure to mentoring during an in-service student mentoring program
Get PDFAbstracts in English, Afrikaans and Northern SothoThe novice-teacher entering the profession, may have the calling to teach, but might lack the necessary knowledge and skills required for effective teaching. This could be a result of receiving insufficient mentoring as a student-teacher. The researcher adopted a qualitative research approach to observe six participants in their classrooms. Three participants had a direct transition from being a student-teacher to becoming a novice-teacher, relying only on their mandatory practical training. The other three participants participated in an in-service mentoring program while completing their studies and mandatory practical training. The study evaluated what impact the in-service mentoring program had on these novice-teachers. Using questionnaires, interviews, and classroom observations the researcher’s finding is that the in-service mentoring program participants were more prepared for the teaching profession. The result of the study supports the hypothesis that exposure to mentoring during an in-service mentoring program is beneficial for the novice-teacher, the school and ultimately the learners.Beginneronderwysers wat die beroep betree, mag dalk ’n roeping vir die onderwys hê, maar het moontlik nie die kennis en vaardighede wat nodig is vir effektiewe onderrig nie. ’n Moontlike rede hiervoor is onvoldoende mentorskap gedurende hulle tyd as studente-onderwysers. Die navorser het ’n kwalitatiewe navorsingsbenadering gevolg om ses deelnemers in hulle klaskamers waar te neem. Drie van die deelnemers het ’n direkte oorgang van studente-onderwyser tot beginneronderwyser ondergaan, en het slegs hulle verpligte praktiese opleiding gehad om op te steun. Die ander drie deelnemers het aan ’n indiensmentorskapprogram deelgeneem terwyl hulle studeer en die verpligte praktiese opleiding voltooi het. Die studie het die effek van die indiensmentorskapprogram op hierdie beginneronderwysers geëvalueer. Die navorser het aan die hand van vraelyste, onderhoude en klaskamerwaarneming bevind dat die beginneronderwysers wat aan die indiensmentorskapprogram deelgeneem het, beter op die onderwysberoep voorbereid was as die ander beginneronderwysers. Die uitslag van die studie ondersteun die hipotese dat blootstelling aan mentorskap as deel van ’n indiensmentorskapprogram voordelig is vir beginneronderwysers, skole en, op die duur, leerders.Morutisi wa go hloka boitemogelo bjo bo lekanego yo a thomago ka mosomo, a ka ba le pitso ya go ruta, eupsa a hloka bokgoni le tsebo ye e hlokegago go ruta gabotse.

Anti-fungal, anti-mycotoxigenic activity and phytochemical spectra of selected South African plants
Get PDFInhibition of in vitro mycelial growth against six mycotoxigenic fungal pathogens in vitro of six medicinal plants leaves extracts to check potential of anti-mycotoxigenic activity . Organic extract from Strychnos mitis exhibited a noteworthy antifungal activity yielding lowest minimum inhibitory concentration (MIC) value of 0.01 mg/ml against three Furasium species (Furasium vercitilloides, Furasium oxysporum and Furasium graminareum) and a further MIC value of 0.08 mg/ml against Aspergillus parasiticus, Aspergillus flavus and Aspergillus ochraceous at 24 hr incubation period. At both 24 and 48 hr incubation period, aqueous extract from Mystroxylon aethiopicum yielded MIC value of 0.02 mg/ml against A. parasiticus while aqueous extract from Spirostachys africana exhibited MIC values of 0.04 and 0.02 mg/ml against F. vercitilloides and F. graminareum at 48 hr respectively. In the mycelial growth inhibition (MGI) studies, the extracts showed varying degree of inhibition in a dose dependent manner. M. aethiopicum showed the highest mycelial growth percentage inhibition of 44.38 against Fusarium verticiloides in a three-day incubation period. Furthermore, the organic extracts were also evaluated for cytotoxicity effects against both African green monkey (Vero) and Bovine dermis (skin) cell lines using the MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay. Organic extract from S. africana exhibited the lowest lethal concentration (LC50) value of 0.10 mg/ml against both cell lines used in the study, while S. mitis exhibited the highest selectivity index (SI) value of 88.0 against F. graminareum. In the antioxidants assays, only extracts from S. africana and M. aethiopicum exhibited a noteworthy activity against 2,2-Diphenyl-1-picrylhydrazyl (DPPH), 2-2′-Azino-di-[3-ethylbenzthiazoline sulfonate (ABTS) and chelation of iron.The extracts, with potent biological activity, were also subjected to Gas-chromatography-mass spectrometry (GC-MS) analysis to identify the presence and prevalence of phytocompounds. M. aethiopicum extract exhibited the presence of tetradecane (15.74%) and heptadecane (14.96%), while S. africana yielded n-hexadecanoic acid (12.14%) and nonadecane,2-methyl (12.14%). These results suggest that bio-compounds from plants can be further explored in vivo and used to develop a bio-fungicide with less side effects compared to synthetic fungicides. Elsewhere, tetradecane, heptadecane and n-decanoic acid were reported to inhibit the mycelial growth inhibition of various mycotoxigenic fungal strains.M. Sc. (Life Sciences)Life and Consumer Science
An Analysis of Trends in Shareholder Activism in South Africa
Get PDFThere has been a progressive shift in shareholder activism in South Africa as shareholder demands for greater levels of accountability, reasonable executive remuneration and disclosure and transparency are increasing. Frustration with increasing high-profile corporate scandals and governance failures has also caused shareholder activism to gain momentum in South Africa. This article discusses the South African legal framework relating to shareholder activism and identifies trends in shareholder activism in South Africa. While the growing increase in shareholder activism is welcomed, this article contends that South Africa still has a long way to go compared to the level of shareholder activism in the USA, the UK and Australia. Recommendations are made to enhance shareholder activism in South Africa.College of La
The impact of online skills on teaching and learning during covid-19 at a selected school in Kempton Park, Johannesburg
Get PDFWhen COVID-19 struck, resulting in the closure of schools and a shift to online learning, the inadequacies in the South African education system were laid bare, especially teacher and learner preparedness to embark on online learning. Documents such as White Paper on e-Education are awash with ideas on how to equip educators and learners with online skills. Yet, such ideas remain on paper, with many educators, especially those teaching in public schools and learners from poor households bearing the brunt. The shift to online learning saw educators and learners pushed to territories they were not familiar with. The purpose of the study was to explore the impact of online skills on teaching and learning during COVID-19 at a selected high school in Kempton Park, Johannesburg. The study adopted a qualitative approach. Two Heads of Departments (Post level 2), four educators (Post level 1) and four Grade 12 learners were purposefully sampled to participate in the study. Thematic analysis was used to analyse data. The study revealed that educators and learners experienced multiple challenges while learning online. They lacked online skills, and there was little support given to them by the Department of Education and the school in general. Based on the challenges experienced, the study recommends that educators and learners be equipped with relevant skills and resources. The government must invest in school infrastructure to ensure effective online learning for all learners, regardless of their background or school. In addition, policies that support online learning must be implemented.M. Ed. (Educational Leadership and Management)Educational Leadership and Managemen
