- Description: The synthesis and characterization of the new zinc phthalocyanine derivatives, tetra- (non-peripheral, 5) and octa-(peripheral, 6) substituted with 2-mercaptopyridine and their respective quaternized derivatives (8 and 9) are reported. Photochemical and photophysical properties of the new complexes are compared with those of the previously reported peripherally tetra-substituted complexes 7 and 10. The quaternized compounds exhibit excellent solubility in water, making them potential photosensitizers for use in photodynamic therapy (PDT) of cancer. Spectroscopic, aggregation, photophysical and photochemical properties of these complexes are also investigated and compared. Photophysical (fluorescence quantum yields and lifetimes) and photochemical (singlet oxygen and photodegradation quantum yield) properties of these phthalocyanine photosensitizers are very important for the assessment of these complexes as PDT agents. In this study, the effects of the position of the substituents and quaternization of the substituents on the photophysical and photochemical parameters of the zinc phthalocyanines are also reported. This study also showed that the water-soluble quaternized zinc phthalocyanines strongly bind to blood plasma proteins such as bovine serum albumin (BSA).

- Description: The research seeks to explore why women in Zimbabwe still face hindrances in accessing micro finance services and what can be done to meet their needs in a more holistic and effective way. Women play a crucial role in the economic development of their families and communities but are faced with certain obstacles that hinder them from performing their role effectively. Such hindrances as poverty, unemployment, low household income and societal discrimination. UNIFEM (1992) confirms that the majority of the world‟s poor have a predominantly female face and argues that women earn only 10 percent of world‟s income and own less than 10 percent of the world‟s property. African women have been characterised by the lack of empowerment caused by societal perceptions and negative cultural practice. In many cases of women rights violation it has been noted that this has been exacerbated by the over reliance on the male counterpart. Development practitioners have noted that micro finance as one of the strategies needed for women empowerment. Despite the concept having been practiced for at least 15 years now, women still face challenges in accessing micro finance services. There is need for Micro Finance Institutions to recognise the position of women in relation to men as actors in society.

- Description: Most cosmetic surgery patients in South Africa are younger than 21, and in this focus we examine narrative accounts from young South African women who have chosen to undergo cosmetic breast reduction surgery. Feminist debates on cosmetic surgery have focused on the question of whether to regard women who modify their bodies in this way as active agents engaged in liberatory ‘body projects’, or whether such projects are evidence of their subjection to oppressive stereotypes and beauty norms. The latter perspective is challenged here by the participants’ characterisation of breast reduction surgery as profoundly ‘freeing’. The article deals in particular with the conscious choice of participants to knowingly risk not being able to breastfeed children in future in order to achieve a body type which conforms to their understanding of youthful beauty and sexuality.

- Description: This thesis explores the Where Leaders Learn slogan of Rhodes University. It does this by means of an analysis of discourses constructing leadership and leadership development within the institutional context. The discourse analysis was made possible as a result of interviews with a range of people involved in leadership and leadership development at the University. The analysis revealed that leadership development is constructed as taking place within a highly structured system that enables instructional and managerial leadership but constrains transformational leadership. The discourses that give meaning and understanding to the construct of leadership draw heavily on position within a hierarchy. The discourse of functional efficiency is enabled through practices related to reward, recognition, succession planning and mentorship which all serve to replicate the existing leadership structures creating more of the same and in essence stifling the potential for emancipatory leadership. The analysis also shows that a discourse of collegiality serves to create a false sense of a common understanding of leadership in the light of evidence of uncertainty and contestation around the meaning of the slogan Where Leaders Learn and, by association, the very construct of leadership. The discursive process of understanding leadership and developing an institutional theory for the purposes of infusing this into a curriculum poses many challenges. Barriers to new ways of thinking reside within the researchers' ontological and epistemological commitments. This amplifies the need for a more reflective ontology towards leadership and its consequences, especially so in a multidisciplinary environment such as Rhodes University.

- Description: This study was conducted on the mourning rituals of the AmaXhosa widows of the Eastern Cape Province of South Africa. The study focused on the descriptive presentation of the experiences of the AmaXhosa widows in the Buffalo City municipality of the Province. The study sought to establish the widows’ perceptions regarding the mourning rituals and to interpret their experiences within the context of contemporary cultural, religious, gender and socio-political influences. The experiences among the widows interviewed were found to have a similar context but their perceptions about the mourning rituals were different between the widows younger than 40 years and those older than 50 years. Widows from urban and rural areas of East London, Mdantsane Township and from within a 60 kilometre radius of East London were interviewed. Purposive random sampling was used to identify an equal number of either urban or rural voluntary participants for the study. Structured interviews were held with widows ranging in age from 29 to 91 years. An interpretative phenomenological analysis of the recorded discussions was conducted. The experiences of the AmaXhosa widows during the conduct of the mourning rituals are described. The key findings of the study indicated that most of the widows felt they had to go through the mourning rituals mainly to show respect for their departed husbands and so that the dignity of the family and clan was maintained. The mourning rituals seemed mostly to have negative implications for the widows such as a lack of family and financial support and being treated as social outcasts; however the rituals also seemed to help the women adjust to their new status as widows. Although the mourning rituals were embedded in the socio-cultural tradition generally followed by the AmaXhosa, religious beliefs also influenced some of the traditions by introducing changes in the way some widows conducted the mourning rituals. For example, some religions advocated for shorter periods of mourning than usual as well as wearing different types of mourning clothes from the usual black or purple dress. Overall the perceptions of the older widows aged above 50 years revealed that they had no reservations about performing the mourning rituals and quite readily and unquestioningly accepted the customs. The younger widows aged below 40 years on the other hand felt that the mourning rituals were biased against women and did not serve a useful purpose and even proposed changes to the manner in which the mourning rituals are conducted particularly the shortening of the mourning period from 12 to 6 months or less. However, they seemed to recognize the role played by the mourning ritual in lessening and possibly healing the pain and sorrow caused by their bereavement.

Willingness to pay for water quality changes in the Swartkops Estuary

- Description: South Africa, like the rest of the world, is vulnerable to the impact of climate change and loss of biodiversity. Water pollution is one of the six global threats to freshwater biodiversity. The future health status and productivity of South Africa’s estuaries is dependent on two main factors: management and quality and quantity of freshwater inputs. South Africa has around 250 functioning estuaries along its 3000 km coastline (Hosking 2004). They play an invaluable role in ecosystem functioning and biodiversity conservation. Estuaries are amongst the richest and most productive parts of the marine environment and as such call for careful management. Some of these ecosystems are focus areas for urban an industrial development. Urbanization and industrialization pose a serious threat to these sensitive systems. Increased water pollution from domestic use, industry and agriculture affect the ecology of these estuarine, river and lake systems. A large number of South African estuaries are still in excellent or good condition, but these are mainly the very small systems. The larger systems, like the Swartkops estuary, often very important in terms of conservation value, are also often compromised in some way or other. The reasons why they are compromised include habitat destruction, artificial breaching and pollution, especially those close to urban areas. This situation is aggravated by outdated and inadequate sewage treatment plant infrastructure and unskilled operators that dispose untreated waste into these systems. Pollution into estuaries can result in the partial loss of the environmental service flows supplied by them. The result of lost environmental service flows has adverse consequences, such as diminished residential and holiday recreational appeal, as well as reduced capacity to support subsistence livelihoods. Poor water quality not only limits its utilisation value, but is also places added economic burden on society, through both the primary treatment costs and the secondary impacts on the economy. Healthy estuarine ecosystems are essential for the maintenance of biodiversity and a wide range of environmental goods and services. Without a drastic improvement in water quality management approaches and treatment technologies, the continuous deterioration in water quality will decrease benefits and increase costs affiliated with use of these water resources.The market-based system of the South African economy has to a large extent failed to account for the value of the “free” goods and services provided by the natural environment. When the true value of the natural resources is unknown, there is a risk that less financial resources and capacity are made available to manage and protect these natural resources than is efficient. To ensure that these goods are properly taken into account, they must be valued and these values incorporated in social decision making. This study uses the contingent valuation method (CVM) to establish the value of the Swartkops estuary for changes to water quality. The CVM is a non-market valuation method that is widely used in cost-benefit analysis and environmental impact assessment. The CVM establishes the economic value of the good by asking the users of an environmental good to state their willingness to pay for a hypothetical scenario to prevent, or bring about, certain changes in the current condition of the environmental good. This method is subjected to some criticism. This criticism revolves around the validity and the reliability of estimated results and the effects of various biases and errors on them. The North Oceanic and Atmospheric Administration (NOAA) Blue-Ribbon panel investigating the validity of the CVM resolved that the CVM can be used to guide social decision making, if a series of guidelines are followed. The Swartkops contingent valuation (CV) was conducted with these guidelines in mind. The results of the Swartkops CV indicate that the user population has a total willingness to pay (TWTP) of R68848 (median bid) and R203632 (mean bid) annually for the implementation of a project to improve the water quality in the Swartkops estuary. User population is an important determinant of the TWTP value. As a result, using a more broadly defined user population, TWTP per annum was calculated to be R3481987 (median bid) and R10298688 (mean bid). Management of natural resources should be informed by values that reflect efficient balances, so as to obtain the most efficient use of them (Trupie 2008). Polluted water inflows into South Africa’s estuaries are a threat to their biodiversity. Healthy estuarine ecosystems are essential for the maintenance of biodiversity and human well-being (Water Assessment Programme Report 2006: 15). As a result, this study recommends that a project be implemented by the Nelson Mandela Bay Municipality to improve water quality in the Swartkops estuary.

Automation of common manufacturing operations is one of these methods. By automating common manufacturing operations; various machines, robots, control systems and information technologies are used to reduce the overall human input requirement (mental and physical). Recent advances in technology have made it possible to now also automate (or facilitate) the maintenance requirement of these machines and tools. Modern tools and machines, which can estimate when it will fail or when failure is imminent have obvious advantages for predictive maintenance purposes. Another function of this technology is to determine how efficiently a tool or machine operates, or what the quality of the produced goods is. Predictive maintenance can decrease manufacturing plant or machine down times – which have a positive effect on cost-savings – has gained considerable importance over the last two decades.

- Description: This research looks at the process of women’s empowerment in post- 1994 Rwanda, with special focus on twelve cooperatives working in Mayaga region and the way these cooperatives empower women, their households and the community at large. Traditional Rwandan society has been always bound by patriarchy which has not valued the reproductive roles of women as economically productive in their households and the society as a whole. On the one hand, this understanding was reversed in the post-1994 Rwanda by the commitment of the government to gender equality at the highest level of political leadership through progressive policies and legislation. On the other hand, in Mayaga region, cooperatives brought about socio-economic development and changed relationships of gender and power in a patriarchal post-conflict society. The findings from cooperatives in Mayaga region show that to prevent women from reaching their full potential is economic folly. If women are empowered, they can generate important development outcomes such as improved health, education, income levels and conflict resolution. The findings further indicate how women’s empowerment is determined by the livelihood strategies women adopt themselves to respond to their vulnerability, and by the ways in which they express their agency in making a living in a sustainable way, with the available community assets that they have access to (financial, social, human, natural and physical). This research highlights that the accessibility of the community assets used by women in Mayaga region and in Rwanda as a whole is also determined by policies, institutions and processes that are able to influence their livelihoods positively.

- Description: This research looks at the process of women’s empowerment in post- 1994 Rwanda, with special focus on twelve cooperatives working in Mayaga region and the way these cooperatives empower women, their households and the community at large. Traditional Rwandan society has been always bound by patriarchy which has not valued the reproductive roles of women as economically productive in their households and the society as a whole. On the one hand, this understanding was reversed in the post-1994 Rwanda by the commitment of the government to gender equality at the highest level of political leadership through progressive policies and legislation. On the other hand, in Mayaga region, cooperatives brought about socio-economic development and changed relationships of gender and power in a patriarchal post-conflict society. The findings from cooperatives in Mayaga region show that to prevent women from reaching their full potential is economic folly. If women are empowered, they can generate important development outcomes such as improved health, education, income levels and conflict resolution. The findings further indicate how women’s empowerment is determined by the livelihood strategies women adopt themselves to respond to their vulnerability, and by the ways in which they express their agency in making a living in a sustainable way, with the available community assets that they have access to (financial, social, human, natural and physical). This research highlights that the accessibility of the community assets used by women in Mayaga region and in Rwanda as a whole is also determined by policies, institutions and processes that are able to influence their livelihoods positively.

- Description: The study examines work-family conflict, stress, and some demographic and occupational variables among female factory workers in East London, South Africa. The participants were female factory workers in East London, South Africa. The independent variables for the study were, demographic and occupational variables, while stress is the dependent variable. Work-family conflict is dependent on demographic and occupational variables, while on the other hand is independent to stress. The demographic variables concerned are age, marital status, number of children and age of the last born child. The occupational variable on the other hand is occupational level, i.e. managerial versus non-managerial. The measuring instruments were a self-designed questionnaire to measure the demographic and occupational variables, a questionnaire developed by Stephens and Sommer (1996) to measure work-family conflict (cronbach’s alpha = 0,90) and the Effort – Reward Imbalance (ERI) questionnaire (Pikhart, Bobak, Siegrist, Pajak, Rywick, Kyshegyi, Gostaus, Skodova& Marmot, 1996) to measure stress at workplace. Cronbach’s alpha for the whole questionnaire reaches the value of 0,89. , Thesis (MCom) -- Faculty of Management and Commerce, 2011

- Description: This research report aims to explore the potential of an Asset-Based Community Development (ABCD) approach in Leliefontein. Through the ABCD process, an inventory of the individual capacities of a sample group will be undertaken, as well as an inventory of the significant local associations, organisations and institutions, as well as their capacities. The objective will be to use the asset-mapping process to challenge negative community self-perceptions, enabling them to build new, positive images that empower and release latent potential. The information gathered will also be made available to the individuals, organisations, associations and institutions within the community, along with some ideas on how mutually beneficial partnerships can be developed. The key objective will be to assist the community of Leliefontein, to no longer regard themselves from a deficit mindset, but positively, as a community with tremendous resources, assets and relationships that can be harnessed for 4 community economic development. Asset-mapping can then be used by local organisations to build new relationships within the community, as well as relationships that harness resources outside of the immediate community.

The presence of foreigners, especially those from Africa is in contention. Some argue that they help the economy whilst others argue they are a hindrance to locals and their employment worth. The “truth” regarding these may not be immediately recognisable and thus open to questioning depending on perception. The press plays a large role in these perceptions and has been criticised for the way it covers issues of public interest. it is envisaged that this study will be a useful contribution to the limited body of literature on xenophobia and media. The purpose of the study is to give foundation to the assumption that the media's constantly negative coverage of foreigner poses a very real threat to human rights as purported in South Africa‟s constitution, in addition to the economic significance, whether positive or not. This study highlights the perception that Nelson Mandela Bay residents have of foreign nationals, and whether negative reporting in the media has influenced residents' views of foreign nationals.

- Description: Zimbabwe’s land reform is the first book on contemporary Zimbabwe that offers an empirically-rich and detailed account of redistributed farms that arose from ‘fasttrack’ land reform 10 years ago. In order to fully appreciate the significance of this book, it is necessary to outline briefly recent intellectual debates on Zimbabwe. Two main positions exist on Zimbabwean politics and society. The first position argues that the radical restructuring of agrarian relations (including undermining white agricultural capital and breaking up large commercial farms into smaller units) is a progressive tendency that has opened up opportunities for black small-scale farmers. Simultaneously, this position often underplays the existence of state restructuring of an authoritarian kind. The second position argues that land redistribution has dramatically undercut agricultural production thereby severely compromising food security for all Zimbabweans. It brings to the fore violent state action in instigating land occupations and in thwarting political opposition to ‘fast-track’.

- Description: Why, despite evidence to the contrary, does the narrative of the negative consequences of teenage pregnancy, abortion and childbearing persist? This book outlines a critical view of "teenage pregnancy" and abortion, arguing that the negativity surrounding early reproduction is underpinned by a particular understanding of adolescence. The book traces the invention of "adolescence" and the imaginary wall that the notion of "adolescence" constructs between young people and adults. It examines the entrenched status of "adolescence" within a colonialist discourse that equates development of the individual with the development of civilisation, and the consequent threat of degeneration that is implied in the very notion of "adolescence". Many important issues are explored, such as the ideologies and contradictions contained within the notion of "adolescence"; the invention of teenage pregnancy as a social problem; the construction of abortion as the new social problem; issues of race, culture and tradition in relation to teenage pregnancy; and health service provider practices, specifically in relation to managing risk. In the final chapter, an argument is made for a shift from the signifier "teenage pregnancy" to "unwanted pregnancy". Using data gathered from studies from four continents, this book highlights central issues in the global debate concerning teenage pregnancy. It is suitable for academics, postgraduate and undergraduate students of health psychology, women’s studies, nursing and sociology, as well as practitioners in the fields of youth and social work, medicine and counselling.

- Description: Women's magazines are popular cultural forms which offer readers representations intended to advise women on how to work towards and achieve idealised femininities. They perform such a function within the wider socio-historical context of gender relations. In a country such as South Africa, where patriarchal gender relations have historically been structured to favour men over women and masculinity over femininity, the representation of femininity in contemporary women's magazines may serve to reinforce or challenge these existent unequal gender relations. Informed by a feminist poststructuralist understanding of the gendered positioning of subjects through discourse, this study is a textual analysis that investigates the subject positions or possible identities offered to readers of Destiny, a South African business and lifestyle women's magazine. Black women, who make up the majority of Destiny's readership, have historically been excluded from the formal economy. In light of such a background, Destiny offers black women readers, through its representations of well-known business women, possible identities to take up within the white male dominated field of business practice. The magazine also offers 'lifestyle content', which suggests to readers possible ways of being in other areas of social life. Through a method of critical discourse analysis, this study critically analyses the subject positions offered to readers of Destiny, in order to determine to what extent the magazine's representations of business women endorse or confront unequal gender relations. The findings of this study are that Destiny offers women complex subject positions which simultaneously challenge and reassert patriarchy. While offering readers positions from which to challenge race based gender discrimination – a legacy of the apartheid past – the texts analysed tend to neglect non-racially motivated gender prejudice. It is concluded that although not comprehensively challenging unequal gender relations, the magazine whittles away some tenets of patriarchy.

Relationship marketing concerns the facilitation and managing of the relationships between the business and its customers and was developed as a response to the realisation that businesses were spending vast resources in time and money to attract new customers but very little on retaining existing ones. Relationship marketing is particularly relevant when a customer has alternative service providers to choose from, when the customer makes the selection decision and when there is an ongoing desire or need for a product or service, such as in the banking industry (Morgan & Hunt 1999).

The structures of these compounds were characterized by using elemental analyses, UV–Vis, FT-IR, 1H NMR and mass spectroscopies. Their photophysical properties were also studied. The ΦF values are 0.12, 0.02, 0.10, 0.06, 0.10, 0.06, 0.65, 0.80 and the ΦT values are 0.58, 0.56, 0.57, 0.64, 0.22, 0.48, 0.17, 0.12 for 4–8, respectively. The ΦF value for complex 8 is higher than ever reported for phthalocyanine complexes. The triplet lifetimes (τT) values for all the complexes were generally good, ranging from 50 to 310 μs, and generally increased in the presence of the single carboxyl group. These complexes showed reasonable triplet quantum yields and lifetimes, and hence have potential for use as photosensitizers in photodynamic therapy (PDT) of cancer.
