  • Description: The synthesis and characterization of 2,9,16,23-chloro-3,10,17,24-triethyleneoxysulphanylphthalocyaninato zinc(II) (CTESZnPc) is described. The photophysics and photochemistry of CTESZnPc and those of tetrakis(triethyleneoxysulphanyl)zinc phthalocyanine (TTESZnPc) and octakis(triethyleneoxysulphanyl)zinc phthalocyanine (OTESZnPc), are presented and compared with those of unsubstituted zinc phthalocyanine (ZnPc). The presence of triethyleneoxysulphanyl substituents on the ZnPc ring gave rise to higher values of singlet oxygen (ΦΔ) and photodegradation (ΦPd) quantum yields in DMF. However, TTESZnPc, OTESZnPc and CTESZnPc are less fluorescent than ZnPc, judging from their fluorescence quantum yield (ΦF) values. Fluorescence was lower in toluene than in DMF due to aggregation in the former solvent. Triplet quantum yield (ΦT) values were found to increase with the presence of substituents on the ZnPc ring, while triplet lifetimes (τT) were found to vary linearly with the logarithms of solvent viscosities. The fluorescences of the substituted ZnPc complexes were effectively quenched by benzoquinone (BQ), and the quenching data analyzed by the Stern–Volmer equation. The Stern–Volmer constants and the diffusion-controlled bimolecular rate constants were calculated.

  • Description: Three non-peripherally substituted tin(IV) macrocylic compounds, octahexylphthalocyaninato dichlorotin(IV) (35a), octahexyltetrabenzo-5,10,15-triazaporphyrinato dichlorotin(IV) (35b) and octadecylphthalocyaninato dichlorotin(IV) (35c) were synthesized and their photophysical and electrochemical behaviour studied. Complex (35b), containing a CH group in place of one of the aza nitrogen atom of the phthalocyanine core, shows a split Q band due to its lower symmetry. The triplet state quantum yields were found to be lower than would be expected on the basis of the heavy atom effect of tin as the central metal for phthalocyanine derivatives (35a and 35c). In contrast, (35b) shows a triplet quantum yield ΦT = 0.78. The triplet state lifetimes were solvent dependent, and were higher in THF than in toluene. Cyclic voltammetry and spectroelectrochemistry of the complexes revealed only ring based redox processes. This thesis also reports on the microwave syntheses of tetrasulphonated tin phthalocyanine and tetrasulphonated tin α,β,γ-tetrabenzcorrole. The latter was only formed at low ratios (< 1:8) of 4-sulfophthalic acid to urea. Both complexes are aggregated in aqueous media, but can be partly or fully disaggregated by the addition of Triton X-100. The SnTSTBC complex has lower triplet life times and yields, while binding constant and quenching (of bovine serum albumin) constant are lower for SnTSTBC, compared to SnTSPc. Finally Non-peripherally (α) tetra- (40) and octa-(38a) substituted dodecyl-mercapto tin(IV) phthalocyanines where synthesized and the electrochemical behavior studied. Cyclic voltammetry and spectroelectrochemistry show ring-based reductions for (38a) and (40); the former shows two ring oxidations, while the latter shows only one ring based oxidation. The adsorption kinetics of (38a) and (40) on a gold electrode have been investigated by electrochemical impedance spectroscopy (EIS). The equilibrium constant (K) for the adsorption and the Gibbs free energy ΔG(ads) of the self-assembled monolayer (SAMs) were evaluated based on the Frumkin isotherm. The interaction factor between adsorbate –adsorbate molecules is also discussed.

  • Description: This study has been concerned with the design and synthesis of A TP analogues with the potential to act as inhibitors of glutamine synthetase - a novel target for therapeutic intervention in the treatment of tuberculosis. Using a structural -analogy approach, various 3-indolylalkanoic acid, benzimidazole and pyrazolo[3,4-dJpyrimidine derivatives have been prepared and characterized. Alkylation of the heterocyclic bases using 4-(bromomethyl)-2,2-dimethyl-1 ,3-d ioxolane, 2-(bromomethoxy)ethyl acetate and 2-(chloroethoxy)ethanol in the presence of either NaH or BulOK afforded the corresponding N-alkylated derivatives of benzimidazole and 4-aminopyrazolo[3,4-dJpyrimidine (4-APP). Similar reactions with 3-indo lylalkanoic esters resulted in O-alkyl cleavage with the formation of new esters. Alkylation of benzimidazole with allyl bromide, 4-bromobutene and 2-methylbut-2-ene has also been shown to afford the corresponding l-alkenylbenzimidazoles in moderate to excellent yield (43-96%). Subsequent oxidation of these products using CTAP, gave the dihydroxy derivatives in poor to good yields (26-77%). Phosphorylation of various hydroxy derivatives of benzimidazole and 4-APP has been achieved using diethyl chlorophosphate to afford the corresponding monophosphate and 1,2-diphosphate esters. Glycosylation of each of the heterocyclic bases has been successfully achieved using 1,2,3,4,6-penta-O-acetyl-D-glucopyranose and SnCl4 in acetonitri le, while methanolysis of the resulting tetraacetates, using methanolic NaOMe, afforded the hydroxy derivatives in good yield (50-70%). Various 1- and 2-dimensional NMR spectroscopic methods (e.g., IH, 13C, lip, COSY, HSQC and HMBC) have been used to confirm the structures of the synthesized A IP analogues. The application of NMR prediction programmes has been explored, permitting assessment of their agreement with the experimental data and confirmation of assigned structures. High-resolution electron impact (EI) mass spectrometric data have been used to explore the mass fragmentation pathways exhibited by selected derivatives, and certain common fragmentations have been identified. Molecular modelling of selected products as potential glutamine synthetase ligands has been performed on the Accelrys Cerius2 platform, and interactive receptor-ligand docking studies have been conducted using the Ligand-Fit module. These studies have revealed possible hydrogen-boding interactions between the selected analogues and various amino acid residues in the glutamine synthetase active site.

  • Description: Transactions conducted using the Internet have expanded dramatically in the past few years and countries and their governments have become concerned about the consequences that electronic commerce may have on their tax revenues. Because of this many organisations and inter-governmental agencies have met to try to design a solution that will be compatible with the systems of the various countries and achieve tax neutrality. A number of proposals were made and discussed to try to design a fair and efficient e-tax system. The proposed system that is ultimately adopted must consider different tax bases and systems in order to achieve this. In this research the impact of e-commerce on the imposition of income tax was briefly referred to and four different proposals for levying value-added tax or sales tax were analysed in order to compare the advantages and disadvantages of each and to determine which system would most adequately address the needs of e-commerce. Certain modifications and additions to the proposed systems have been suggested in order to satisfy the specific needs of the South African tax system, while still taking other countries’ tax systems into account. Using Amazon.com Inc. and Skype Technologies South Africa Limited as examples, it is demonstrated how the new amended system will work. It was found that the proposed systems and the system adapted to meet the South African needs would, with a few relatively minor changes to the Value-Added Tax legislation, be suitable for the purposes of imposing value-added tax on e-commerce transactions.

  • Description: Participative management, a key theme in contemporary management literature, is one of the central aims of the decentralization policy in Namibian education. Current perceptions of participative management on the part of teachers in Namibia are therefore of topical interest. This study set out to explore such perceptions among teachers in a Namibian primary school. The study is an interpretive case study focusing on six individual teachers’ understanding and experience of participative management within their place of work, a primary school in the Oshikoto region of Namibia. Semi-structured interviews, observation and document analysis were used to gather data. The study revealed a strong sense of commitment among the respondents to participative management and its accompanying practices, such as shared decision making and broad stakeholder involvement. Participative management was implemented chiefly through a committee structure for school organisation and government. Respondents also highlighted challenges facing participative management, such as the persistence of autocratic leadership, conflicts of interest in decision making, laziness and unwillingness among staff members, and a lack of understanding among parents concerning their role in the schooling of their children. HIV/AIDS was also seen to pose challenges to the free and frequent participation of stakeholders. The chief recommendation arising from these findings is that school leaders and managers’ understanding of tenets of participative management, such as site-based management and democratic management approaches, requires improvement and development.

  • Description: Literacy is currently a topic of great concern in Namibia. Learners in this country have difficulty in reading and writing, and are often functionally illiterate. This study focuses on the beliefs, experiences and practices of teachers of reading in English to second language learners in Grade 4. Grade 4 is the transitional grade from mother tongue to English as the medium of instruction. The switch to English makes teaching reading in that language especially challenging. The study is structured according to the case study mode of enquiry, with the target respondents comprising Grade 4 teachers. Classroom observation, interviews and document analysis were used as means of collecting data. The main findings revealed that beliefs and experience had an impact on the way in which reading was taught in this study. It emerged that the teachers’ childhood experiences of literacy and learning to read are perpetuated in their beliefs, their attitudes, their basic conceptualization of reading and their current practices, all of which directly affect the children in their classes. Although the teachers’ professional training also had some influence on their teaching methods, neither of the two teachers interviewed had received much in-service support on how to teach reading, and they depended to a large extent on their recall of how they had learned to read themselves. Both teachers were taught in a traditional, teacher-centered way, involving phonics, rote-learning and drilling. Because they see themselves as competent readers, they believe that these approaches were effective and worth sustaining. Tentative recommendations arising from analysis of the data indicate possible areas for improvement in the teaching of reading, and offer guidelines to help teachers cope with the challenge.

  • Description: Using data drawn from a sample of 80 farmers in the Kat River valley, this thesis presents the results of an assessment of the technical constraints affecting smallholder development and their implications for market access. A review of the relevant literature on the smallholder farm sector, technical change and technical constraints affecting smallholder farmers along with an overview of the agricultural marketing environment in South Africa has been presented. A critical review of the theoretical framework for consideration of technical change in agricultural development, with particular attention to the induced innovation model was undertaken. General information on the institutional set up was obtained by open-ended interviews of community leaders and focus groups. These interviews supplemented information obtained through literature study and document analysis. The other method of data collection employed was the single-visit household survey using structured questionnaires. The demographic and socio-economic characteristics of the surveyed farmers are described in this study. The selection process of the variables influencing market access was done by employing correlation and logistic regression analyses. Correlation analysis was conducted to ascertain the relationship among variables to find out the extent to which they mirror theory or intuition regarding their causation to constraints influencing market access. The logistic model was employed in the step-wise manner using each of key production inputs as response variables sequentially. On the basis of a binary logistic model, it can be concluded that the farmers still operate under a number of technical constraints. The most influential constraints are information, asset ownership, value of agricultural production and extension assistance. The study reflects the previous findings in South Africa that the legacy of apartheid continues to negatively impact on its agricultural economy.

  • Description: This thesis investigates control aspects of the Hartebeeshoek Radio Astronomy Observatory (HartRAO) antenna. The installation of a new 22 GHz receiver has required the pointing accuracy to be improved to less than 4 mdeg. The effect of thermal conditions on the the HartRAO antenna pointing offset is investigated using a variety of modelling techniques including simple geometric modelling, neural networks and Principal Component Analysis (PCA). Convincing results were obtained for the Declination pointing offset, where applying certain model predictions to observations resulted in an improvement in Declination pointing offset from 5.5 mdeg to 3.2 mdeg (≈50%). The Right Ascension pointing model was considerably less convincing with an improvement of approximately from 5.5 mdeg to 4.5 mdeg (≈20%) in the Right Ascension pointing offset. The Declination pointing offset can be modelled sufficiently well to reduce the pointing offset to less than 4 mdeg, however further investigation of the underlying causes is required for the Right Ascension pointing offset.

  • Description: Temporal changes in hydrography affect suspended particulate matter (SPM) composition and distribution in coastal systems, potentially influencing the diets of suspension feeders. Temporal variation in SPM and in the diet of the mussel Perna perna, were investigated using stable isotope analysis. The δ13C and δ15 N ratios of SPM, mussels and macroalgae were determined monthly, with SPM samples collected along a 10 km onshore–offshore transect, over 14 months at Kenton-on-Sea, on the south coast of South Africa. Clear nearshore (0 km) to offshore (10 km) carbon depletion gradients were seen in SPM during all months and extended for 50 km offshore on one occasion. Carbon enrichment of coastal SPM in winter (June–August 2004 and May 2005) indicated temporal changes in the nearshore detrital pool, presumably reflecting changes in macroalgal detritus, linked to local changes in coastal hydrography and algal seasonality. Nitrogen patterns were less clear, with SPM enrichment seen between July and October 2004 from 0 to 10 km. Nearshore SPM demonstrated cyclical patterns in carbon over 24-h periods that correlated closely with tidal cycles and mussel carbon signatures, sampled monthly, demonstrated fluctuations that could not be correlated to seasonal or monthly changes in SPM. Macroalgae showed extreme variability in isotopic signatures, with no discernable patterns. IsoSource mixing models indicated over 50% reliance of mussel tissue on nearshore carbon, highlighting the importance of nearshore SPM in mussel diet. Overall, carbon variation in SPM at both large and small temporal scales can be related to hydrographic processes, but is masked in mussels by long-term isotope integration.

Texts, practices and student learning: a view from the South

  • Description: This article uses ‘close-up’ ethnographic research to provide an account of students’ engagement with learning in a South African university. Broadly based on Halliday’s (1973, 1978, 1994) understanding of texts resulting from contexts, the account challenges dominant constructions of the problems students encounter as stemming from the use of inappropriate ‘approaches’ to learning, the lack of ‘study’ and other skills or problems with proficiency in areas such as writing or language and shows how students’ unfamiliarity with the context of the university leads them to draw on ‘other’ contexts in order to engage with the texts they must read, write and listen to in the course of their studies. This drawing on ‘other’ contexts then results in the texts produced by students, and the practices which give rise to those texts, being inappropriate to the context of the university. Although the research on which the article is based took place in South Africa, it is argued that the theoretical perspective it provides has relevance across other contexts given the increasingly diverse student bodies which characterize higher education across the globe.

  • Description: Much like a photograph, a casts creates a replica of its referent, thereby immobilising the subject in time. While the subject continues in time and hence ages and inevitably dies the replica does not. With this basic notion of fixing a subject, I have built an argument to contextualise my sculptures, which are made using casts of elderly people. In this discussion I have looked at my works through the ideas of different theorists. The main theorist I have cited is Roland Barthes, specifically with regards to his notion of the photograph as discussed in his book Camera Lucida. I have also referenced three particular artists: Rachel Whiteread, Diane Arbus and Churchill Madikida, as I have found each of their works relate to my work in various ways, creating a different reading from each viewpoint.

  • Description: Nicholas Hlobo, a sculptor and performance artist, and Zanele Muholi, a photographer and activist, explore different ways of representing sexuality, particularly homosexuality. It is extremely difficult to discuss African sexuality in light of the stain of colonial attitudes that have exoticised and ascribed hypersexuality to African bodies. Moreover, sexuality is often not discussed in the construction of so-called African traditions and this has contributed to rendering African-ness as an exclusive identity. Tensions within and between categories of African-ness are compounded by constituted regulations. For example, Hlobo investigates the obligation of circumcision which seems to contrast the lifestyle and contexts in which he works and resides, and Muholi represents the existence of homosexual and transgender relations, even within conservative categories. The visual imagery of these two artists investigates the boundaries set by different social constructs. These set boundaries have also affected crimes against bisexual, transgender and homosexual individuals, which are reaching an alarming rate. Hlobo questions the validity of structures that marginalise homosexual individuals through drawing attention to the ambivalence of certain statutes. Muholi seeks to publicise the injustices imposed upon homosexual individuals in order to demonstrate the weight of that crisis. Although the South African legal system condones liberated expressions of sexual identity, due to social prejudices homosexual individuals are still treated as if they are not entitled to basic human rights. As a result, hate-crimes are not reported, and when they are they are not taken seriously. Hlobo and Muholi not only bring these issues to light, but also point out the dilemma inscribed in the social and political history of (South) Africa with regards to collective and individual identities. This thesis seeks to provide an analysis of the visual language used by Hlobo and Muholi to subvert the notion that homosexuality is “un-African” and to complicate concepts of gender, sexuality and identity.

  • Description: The concept of accountability has grown to become an integral part of a broader political and socio-economic transformation. Closely associated to it is the concept of "auditing" which has established itself as a main driving force of accountability and a core means of delivering it. The extent of the rise and expansion of "auditing" has subsequently come to influence every aspect of modern life and this has led to a situation in which practices have had to adapt to the principles of "auditing" processes. Auditing has become prevalent in both the public and private spheres and this impact has far reaching consequences. The concept of "auditing" is evident in the African Peer Review Mechanism (APRM) and is central to its review process. This thesis focuses on the concept of "auditing" in order to illustrate how the APRM has borrowed and applied insights from other disciplinary practices so as to enhance an understanding of accountability and transparency as features of "good governance" and to explicate how these concepts are conceived within the framework of the New Partnership for Africa's Development (NEPAD). It also clarifies the relationship that exists between "peer review" and "auditing" and argues that rather than being considered as two poles marked by distance from each other "auditing" and "peer review" are closely related and mutually constitutive.

  • Description: The following is a case study report on the Cape Town business unit of Standard Bank Properties. The research project falls within the ambit of services marketing which introduces several unique management challenges for service businesses that sell services as a core offering. The principal aim of the case study is to gain an understanding of why customers bank at the business unit and to discover what aspects are critical to customer satisfaction. A further goal of the research is to examine how the business unit could improve customer satisfaction and to highlight any impediments to further improving customer satisfaction at the business unit. It is generally regarded that quality customer service is essential to building customer relationships and hence the research project emphasis on services marketing and customer satisfaction within a financial services context. The paper commences with an overview of the South African Banking Sector and its unique challenges such as the Financial Service Charter and newly introduced legislation such as Financial Intelligence Centre Act. The case study will specifically investigate the property finance industry and a detailed analysis of the business unit's operations and process flow will also be undertaken. The reason for this background information is to assist the reader to understand how the business unit operates. The research project will investigate four unique differences between goods marketing and services marketing whereafter three theoretical propositions are introduced, namely the dyadic interaction and service encounter, the Service Profit Chain and finally Relationship Marketing. Evidence in the form of a narrative will be led from insights obtained from interviews conducted with customers and staff at the business unit against these propositions with support (or otherwise) from independent surveys and documents from the business unit. The result of this analysis is the identification of several areas of concern specifically: New employees and the service encounter, Problems with FICA, Lack of a customer complaint handling system, Empowerment issues, Turnaround times, Reliance on key staff These insights together with the evidence from the literature review will be analysed and several recommendations made to improve customer service and ultimately customer satisfaction at the business unit. Several recommendations for further research are offered as well as the identification of limitations including but not limited to the specificity of the case study report.

  • Description: From the theoretical perspective of René Girard, Walter Benjamin and Jacques Derrida the Rwanda genocide of 1994 may be interpreted as an instance of foundational violence. Given the constant reference in the Rwanda genocide discourse to the failed revolution of 1959, it is perhaps rather a case of deferred foundational violence. Useful as this notion of “foundational violence” may be, as theoretical category it is also hugely challenging because the implicit claim is not just historical (“states are routinely founded on violence”) but analytical (“founding moments are per definition violent”). The result is a profound tension between, on the one hand, the need to understand the event as somehow unexceptional or typical of the founding of new socio-political orders and, on the other hand, the need to judge it as exceptional, an “outrage,” a crime against humanity. This paper treats the tension between the unexceptional and exceptional as aporetic, that is, as a profound puzzle consisting of two equally valid imperatives which are nonetheless mutually exclusive. It is also an attempt to find a way beyond the impasse.

  • Description: Admissions assessment batteries at most South African higher education institutions augment matriculation results with assessment data from cognitive and non-cognitive measures, in order to identify potentially successful students. The Motivated Strategies for Learning Questionnaire (MSLQ) is a non-cognitive measure, developed in the United States of America to assess the motivational orientation and use of learning strategies among college students. Numerous international studies have confirmed the reliability and validity of the MSLQ. Presently only three quantitative studies have been conducted in the South African higher education context, and in these, researchers have focused on the predictive validity, construct validity and reliability of the MSLQ when used with multicultural and multilingual groups of test-takers. An overview of these studies revealed a confirmation of adequate reliability of the MSLQ, and whereas it was established that nine of the fifteen subscales of the MSLQ are significantly related to the academic success of undergraduate students, limited support was found for the construct validity of the measure. As a result of these findings, a lack of qualitative methods for confirming or disconfirming the quantitative results was noted. The general aim of this study was to explore the applicability of the MSLQ in a higher education South African context, with respect to aspects related to bias, through assessing the item content with specific reference to language and cultural appropriateness. This was to ensure that items on the MSLQ did not favour or disadvantage any cultural and language groups. Investigations in this regard are a necessity in a country like South Africa in an effort to promote fair assessment practices. In order to achieve the above-mentioned aim, a quantitative and qualitative approach was utilised following an exploratory-descriptive research method. The researcher employed a non-probability, purposive sampling procedure to select post-graduate participants employed at the Nelson Mandela Metropolitan University (NMMU) to act as expert reviewers. A Bias Review Form was the primary mode of data collection and this enabled the researcher to collect the biographical details of the expert reviewers, their ratings of the language and cultural appropriateness of each item, and their comments, suggestions and recommendations for improving identified problematic items. Descriptive statistics were used to analyse the reviewers’ responses to the short biographical questionnaire included on the Bias Review Form, while frequency counts were calculated based on the reviewers’ responses to the language and cultural appropriateness of each item. The reviewers’ comments were analyzed into themes using Tesch’s model of content analysis. Three main themes relating to potential bias were identified, namely, language, culture and item characteristics. Guba’s model was employed for assessing the trustworthiness of the qualitative data and for data verification.

  • Description: Section 197 of the Labour Relations Act (LRA) in both its original form and in its current form caused much confusion and debate. Originally it was interpreted that section 197 allowed for the automatic transfer of employees in cases where there was a transfer of the whole or part of a business, trade or undertaking as a going concern. That meant that the contracts of employment transfer to the new owner and that the employees could not refuse to be transferred. Various judges were tasked with interpreting this section in its original form and thus different interpretations emerged with the Labour Appeal Court ultimately deciding in the NEHAWU v University of Cape Town matter that employers involved in the transfer can decide between them, not to transfer the employees. The LAC further held that “outsourcing” does not necessarily entail a transfer of a business. Section 197 was amended in 2002 and the effect of the provisions is that the old employer is not required to seek the consent of the employees before their contracts are transferred and that the employment contracts transfer automatically. However, the current section has also raised some difficulties especially relating to: when does a transfer of a business as a going concern take place; what constitutes a “business”; when is an entity part of a business, trade, undertaking or service? A more glaring controversy relates to whether section 197 applies to “second-generation contracting out or outsourcing”. All provisions of the LRA should be interpreted in the context to advance economic development, social justice, labour peace and democratisation of the workplace. One of the primary objects of the LRA is to give effect to and to regulate the fundamental rights of the Constitution of the Republic of South Africa, 1996. Thus section 197 is to be interpreted in light of the objectives of the LRA as well as to promote the spirit, purport and objects of the Bill of Rights. The common law and international law are both important sources of comparison. The common law allows employers who transfer businesses free to decide whether or not the transfer will include the employees of the transferor. International law, particularly the European Union and the United Kingdom, favour the approach that when an entity is transferred, it retains its identity after the transfer and the safeguarding of employee rights in the context of business transfers. European and English jurisprudence have shown that almost any combination of events can constitute a transfer of a business.

The assessment and treatment of post-abortion syndrome : a systematic case study from Southern Africa

  • Authors: Boulind, Melissa , Edwards, David J A

  • Description: This article reports a clinical case study of "Grace", a black Zimbabwean woman with post-abortion syndrome (PAS), a form of post-traumatic stress disorder precipitated by aborting an unwanted pregnancy. She was treated by a middle class white South African trainee Clinical Psychologist. The case narrative documents the assessment and the course of treatment which was guided by ongoing case formulation based on current evidence-based models. Factors that made her vulnerable to developing PTSD included active suppression of the memory of the event and lack of social support. An understanding of these factors was used to guide an effective intervention. In spite of the differences in culture and background between client and therapist, there was considerable commonality in their experience as young women and students who each had to balance personal and occupational priorities. The narrative also highlights the commonalities of Grace's experiences with those reported in the literature on post-abortion syndrome, which is mostly from the U. S. A. and Europe.

  • Description: The current study aimed at assessing the factors contributing to sustainability of Poverty Relief Projects by the Department of Social Development. The study was conducted in the Eastern Cape within Chris Hani District at Sakhizwe Local Municipality. The study employed both quantitative and qualitative research methods. Purposive sampling procedures have been seen as most suitable for this study and have been utilized to identify participants of the study. The sample consisted of thirty project members from six different projects and also included five Community Development Practitioners from the Department of Social Development. Semi- structured interviews, document review and focus group discussion were used to collect data for the study. The data was analyzed using descriptive statistics and thematic methods. The study revealed factors that contribute to the sustainability of the projects. These factors include the capacity of the project members and the departmental officials to implement and monitor the projects. Management and organization of the project plays an important role in determining the sustainability. Active participation of the project members in the planning of the project is important. Stakeholder participation and sharing of expertise is another important factor in determining the sustainability of the projects. Lastly, the study shows that monitoring and evaluation of the progress is necessary to ensure that the project achieve the desired outcome. It is recommended that the Department of Social Development should consider these factors and add them in the checklist before the funding of the project is approved. It is also important to determine the duration of the project in order to be able to measure its impact in a given period of time.
