  • Description: The pharmaceutical industry must worry about managing pharmaceutical waste as it poses a health risk to human beings and its presence in the environment can also contribute to loss of biodiversity. Ngwuluka, Ochekpe, and Odumosu (2011: 11259) state that “Pharmaceuticals, though used to treat and manage diseases, are poisons, which justify the growing concerns about their presence in the environment.” Various forms of pharmaceutical waste exist, Ngwuluka et al. (2011) identified the following forms of pharmaceutical waste: Expired dosage forms, non-reworkable formulations, spilled pharmaceuticals, rejected active pharmaceutical ingredients, expired active pharmaceutical ingredients, and wastewater resulting from the water used for process operations during manufacturing and could come from the water used to clean equipment, pipes and floors, and would contain amongst other materials, chemicals and active pharmaceutical ingredients (APIs). A review on the pharmaceutical industry and the progress they have made in environmental management by generating health, safety and environmental programs, preventing pollution, waste minimization, recycling and reusing materials, investing in projects and facilities to ensure environmental sustainability have been established (Berry & Rondinelli, 2000). Dr. Reddy’s Laboratories is an Indian based pharmaceutical company which imports, markets and sells medicines in South Africa. Dr. Reddy’s has plans to set up a manufacturing plant in South Africa. The purpose of this study is to research waste management practices at Dr. Reddy’s plant in India and to draw parallels between India’s and South Africa’s waste legislation. This is to enable Dr. Reddy’s to review all aspects of its waste management systems, in order to revise where necessary and to improve the overall achievement of its waste management objectives in order to become a more sustainable organisation and to meet South African Waste legislation before setting up a plant in South Africa. 3 ii. Objective of the Evaluation Report The purpose of this research is to evaluate and analyse the development and implementation of a waste management system in a pharmaceutical company, specifically Dr. Reddy’s Laboratories. This is primarily to enable the company to review and analyse all aspects of waste management pertaining to pharmaceutical manufacturing and to revise or improve where necessary to ensure adherence to waste regulations as outlined by government. The following research goals have been also been identified:  To identify and describe waste management practices at Dr. Reddy’s Laboratories, on the inherent assumption by the researcher that the company has a successful waste management strategy that would need to be reviewed to identify areas of improvement before expanding manufacturing facilities into South Africa.  To evaluate, assess and compare similarities and/or differences between the identified South African Legislation for Waste Management with those identified during research conducted at Dr. Reddy’s iii. Importance of the Research Conducted Waste Management is important in that it not only removes from the environment, substances that can be harmful to humans and animals but it also enables an organisation to be more sustainable. According to Seadon (2010: i) “Integrated waste management is considered from a systems’ approach, with a particular emphasis on advancing sustainability”. The study will provide guidance to senior management, shop floor managers and employees who work in Dr. Reddy’s manufacturing plants as well as overall employees at Dr. Reddy’s on how to successfully implement a Waste Management programme to enhance sustainability at the organisation and realise the benefits to the organisation of being more sustainable. Weybrecht (2010) identified the following benefits that companies could gain by adopting sustainable waste management practices: reduced costs, resource preservation, keeping up with legislation, enhanced reputation, business differentiation from competitors, and attraction and retention of quality employees, and customer need satisfaction amongst many other benefits. This research needs to address the gap in analysing waste management practices (with more emphasis on waste treatment, waste minimisation, re-use, recycling and disposal), and implementation and understanding of waste management in the pharmaceutical industry as prior research was done mostly in other chemical industries and not to a large scale in the pharmaceutical industry. South African Waste Legislation, Indian Waste Legislation (as Dr. Reddy’s is based in India), as well as International Pharmaceutical Waste Management Guidelines, and International Pharmaceutical Good Manufacturing Practices provide a framework and benchmark of leading pharmaceutical waste management practices that can guide Dr. Reddy’s Laboratories’ leadership into integrating their waste management practices into their plans of setting up a manufacturing plant in South Africa. 5. Research Methodology This is evaluation research in the form of a case study and the data collection method employed is the conduction of a survey through questionnaires. The evaluation research also involves a document analysis of the organisation’s 2011 and 2012 annual reports, Dr. Reddy’s 2010 Sustainability Report as well as literature compiled by the organisation’s Corporate Communications Division. The research would also include review of existing literature on waste management. v. Structure of Dissertation This dissertation consists of three sections. Section 1: The Evaluation Report The section introduces the research area, provides the objectives of the research, provides contextual background information and describes the rationale for conducting the research. This section further describes Dr. Reddy’s waste management practice as outlined in relevant company documentation; it is also intended to highlight the specific waste management processes that were followed in the formulation and implementation of the waste management strategy. This section further describes the sample and presents the results of the survey, where the results are collated and reviewed in the context of the criteria set in the South African Waste Legislation, Indian Waste Legislation, as well as in International Pharmaceutical Waste Management Guidelines, and International Pharmaceutical Good Manufacturing Practices. The overall findings of this case study suggest that although management at Dr. Reddy’s are satisfied with waste management practices and results achieved at it manufacturing plant, there is however dissatisfaction amongst employees who believe the organisation has not successfully disseminated information and sufficiently trained them on waste management policies, processes and practices. There is therefore a desire amongst employees to be trained and to see the company improve on its waste management processes, this desire is a very important attribute as it indicates that employees at Dr. Reddy understand and are committed to the importance of waste management. Future research should be conducted to measure the legal impact of non-compliance to legislation governing waste management in the pharmaceutical company. Section 2: Literature Review The objective of the literature review is to provide a critical assessment and evaluation of previous research in the field of waste management in general as prior research was done mostly in other industries and not to a large scale in the pharmaceutical industry. The literature review evaluates the key elements of an effective waste management strategy implementation and is followed by a review of literature pertaining to the description of Pharmaceutical waste. Section 3: Research Methodology This section presents a description of how the work in this research was conducted. It presents the research process followed in compiling this case study, represented by the aims and objectives, research methodology and design, data collection techniques and data analysis.

  • Description: Cultivating oyster mushrooms (Pleurotus ostreatus) could have multiple advantages. For example, it can contribute to food security and malnutrition eradication, as a source of healthy and nutritionally rich food. Feeding on lignocellulosic crop/plant residues, these mushroom species also convert waste materials into a wide diversity of products which have multi-beneficial effects to human beings: serving as animal feed and fertiliser, and for protecting and regenerating the environment. Therefore, objectives of the current research were (1) to investigate the use of the rapidly increasing alien plants (Acacia spp.) in South Africa in cultivating of oyster mushroom for dual benefits, income generating and controlling the population of the alien (invasive) plants; (2) to evaluate the use of pineapple residue in the Eastern Cape as sole substrate or as a supplement in the cultivation of oyster mushroom; (3) to determine the effect of mushroom spent substrate, as organic growing media, on growth of tomatoes and controlling nematode population. In an experiment to investigate yield performance of oyster mushroom (Pleurotus ostreatus HK 35) grown on three acacia species [black wattle (BW: Acacia mearnsii) , silver wattle (SW: A. dealbata) and green wattle (GW: A. decurrens)] used as substrates either mixed with 50% maize bran (MB) or 50% wheat straw (WS).

  • Description: Energy demand forecasting, and specifically electricity demand forecasting, is a fun-damental feature in both industry and research. Forecasting techniques assist all electricity market participants in accurate planning, selling and purchasing decisions and strategies. Generation and distribution of electricity require appropriate, precise and accurate forecasting methods. Also accurate forecasting models assist producers, researchers and economists to make proper and beneficial future decisions. There are several research papers, which investigate this fundamental aspect and attempt var-ious statistical techniques. Although weather and economic effects have significant influences on electricity demand, in this study they are purposely eliminated from investigation. This research considers calendar-related effects such as months of the year, weekdays and holidays (that is, public holidays, the day before a public holiday, the day after a public holiday, school holidays, university holidays, Easter holidays and major religious holidays) and includes university exams, general election days, day after elections, and municipal elections in the analysis. Regression analysis, cate-gorical regression and auto-regression are used to illustrate the relationships between response variable and explanatory variables. The main objective of the investigation was to build forecasting models based on this calendar data only and to observe how accurate the models can be without taking into account weather effects and economic effects, hence weather neutral models. Weather and economic factors have to be forecasted, and these forecasts are not so accurate and calendar events are known for sure (error-free). Collecting data for weather and economic factors is costly and time consuming, while obtaining calendar data is relatively easy.

  • Description: Arthropods released for weed biocontrol can have effects other than simply removing biomass and frequently decrease photosynthetic rate more than can be attributed to the mere loss of photosynthetic surface area. Some of this effect may result because biological control agents facilitate the transfer and ingress of deleterious microbes into plant tissues on which they feed. We evaluated this facilitation effect using water hyacinth (Eichhornia crassipes) and a weevil (Neochetina eichhorniae) and compared the reductions in photosynthetic rates between leaves subject to herbivory by adult weevils sterilized with 3.5% chlorine bleach, to those that were unsterilized. The results showed that weevils carried both fungi and bacteria, transferred these to leaves on which they fed, and that microbes and biomass removal contributed almost equally to the 37% decrease in photosynthetic productivity. Hence, maximising the effectiveness of using arthropods that damage leaf surfaces for biocontrol requires the presence of microorganisms that are deleterious to plants.

  • Description: publisher version , Bernheim’s ACSA, a less conventional measure of subjective well-being originally developed for use in a clinical setting, was applied to a sample of black South African township dwellers (n = 1,020) in the Eastern Cape Province. The Anamnestic Comparative Self Assessment is an experiential self-anchoring scale with concrete anchors (Bernheim in Psychologie médicale 15:1625–1626, 1983). Respondents described the ‘best’ and ‘worst’ periods experienced in their lives in their own words and rated their current life situation within these two extremes that served as the end-anchors of an 11-point rating scale, ACSA. The ACSA score was significantly positively correlated with conventional measures of subjective well-being. The study examined in detail the content of the ACSA anchors, the best and worst periods of respondents’ lives, classified by domain, to gain insights into reference comparisons applied in quality-of-life evaluation in a developing country setting. As was the case in earlier ACSA studies, most domains that served as reference standards were related to the self and family life. However, material living standards, represented by the domains of income, financial security and housing also featured prominently as personal anchors—a reflection of life goals in post-apartheid South Africa. Age, gender, education and self-reported health were associated with the choice of select anchors. The discussion provides pointers for future applications of ACSA in large sample surveys using a pre-coded multiple-choice format for anchor descriptions. It is concluded that the content of ACSA anchors corresponds closely to contemporary definitions of the good life among ordinary South Africans.

  • Description: Effective leadership has been found to be a key determinant of organisational success. Effective leadership does not only involve the ability to influence and inspire others, it is the ability to lead subordinates according to the competencies that they value. The focus of this study is on determining what in fact the future South African graduate workforce will value in a leader. Effective leadership and the competencies that subordinate's value is especially relevant today as leadership is forced to contend with an increasingly diverse workforce. This diversity necessitates the need for a leadership style to be congruent with what subordinates of diverse genders and cultures will value, so to be effective. Existing studies have indicated that gender and culture influence what subordinate's value in a leader, however it is evident from the results of this study, that this is not entirely the case. Regarding gender, the female and male respondents in this study value similar competencies in their leader, indicating that there is no distinct set of competencies that will be valued by male and female graduates. With respect to culture, the respondents value a mixture of competencies that combine both African and Western leadership practices, values and philosophies, indicating that there is no distinct set of competencies that will be valued by African, Coloured, Indian and White graduates. On the basis of this research, the recommendation is that for leaders to be effective in the 21 st century, a leader must be loyal and inspirational, have vision and integrity and lastly must be open and honest with their subordinates

What to expect when you’re not expecting : child-freedom, social stigma, and online subjectivities

  • Description: From Introduction: Today I’m presenting some of the preliminary findings of a study about voluntary childlessness conducted with Indian, Polish, and fellow South African collaborators. Voluntary childlessness is also frequently referred to as being childless by choice or childfree. The term childfree (as opposed to ‘childless’) is intended to show that not having children “can be an active and fulfilling choice”, and to indicate agency and freedom from social obligation. The distinguishing feature of voluntary childlessness is the deliberate avoidance of parenthood, and this is precisely what opens up childfree people, especially married heterosexuals, to greater stigma than the temporarily or involuntarily childless, since it is seen as willing and deliberate deviation from the norm. Having children is seen as a natural consequence of being a “normal” heterosexual woman or man, as well as an expected outcome of marriage. Parenthood is therefore normalised by regulative discourses around sexuality and gender. This process of normalisation is reinforced by pronatalist discourse. According to Meyers, pronatalism rests upon twin strategies: The first is the valorisation or glorification of parenthood, which supports the belief that having children is the only true path to fulfilment. The second strategy is the denigration of non-reproduction in which childlessness is cast as horrific. The result of these dual strategies is to eliminate deliberate childlessness as a possibility. Parenthood, as the only truly viable option for a fulfilling life, is therefore a non-choice. This is compounded by nationalistic and religious rhetoric that constructs childbearing as an obligation or duty. Consequently, as my previous research showed, people often do not reflect on whether to have children or not, but see it more as a matter of timing.

  • Description: International policy analysis tends to simplify the nation state, portraying countries as coherent units that can be described by one statistic or placed into one category. As scholars from Brazil, South Africa, and the USA, we find the nation-centric research perspective particularly challenging. In each of our home countries, the effective influence of the national government on education is quite limited, particularly in fringe and emerging areas of education such as Education for Sustainable Development (ESD) and Climate Change Education (CCE). This essay explores how nation-level comparisons are and are not useful for international research on ESD and CCE. We consider several layers of decentralized governance, but ultimately come to the conclusion that ESD governance in our respective countries is polycentric rather than decentralized. We discuss the implications of this idea for cross-national policy research on ESD and CCE.

When veiled silences speak: reflexivity, trouble and repair as methodological tools for interpreting the unspoken in discourse-based data

  • Description: Researchers who have attempted to make sense of silence in data have generally considered literal silences or such things as laughter. We consider the analysis of veiled silences where participants speak, but their speaking serves as ‘noise’ that ‘veils’, or masks, their inability or unwillingness to talk about a (potentially sensitive) topic. Extending Lisa Mazzei’s ‘problematic of silence’ by using our performativity-performance analytical method, we propose the purposeful use of ‘unusual conversational moves’, the deployment of researcher reflexivity, and the analysis of trouble and repair as methods to expose taken-for-granted normative frameworks in veiled silences. We illustrate the potential of these research practices through reference to our study on men’s involvement in reproductive decision-making, in which participants demonstrated an inability to engage with the topic. The veiled silence that this produced, together with what was said, pointed to the operation of procreative heteronormativity.

  • Description: Publisher version , In the context of widening participation, large classes and increased diversity, assessment of student learning is becoming increasingly problematic in that providing formative feedback aimed at developing student writing proves to be particularly laborious. Although the potential value of peer assessment has been well documented in the literature, the associated administrative burden, also in relation to managing anonymity and intellectual ownership, makes this option less attractive, particularly in large classes. A potential solution involves the use of information and communication technologies to automate the logistics associated with peer assessment in a time-efficient way. However, uptake of such systems in the higher education community is limited, and research in this area is only beginning. This case study reports on the use of the Moodle Workshop module for formative peer assessment of students’ individual work in a first-year introductory macro-economics class of over 800 students. Data were collected through an end-of-course evaluation survey of students. The study found that using the feature-rich Workshop module not only addressed many of the practical challenges associated with paper-based peer assessments, but also provided a range of additional options for enhancing validity and reliability of peer assessments that would not be possible with paper-based systems.

  • Description: The constant strive for improving the efficiency of production processes has become a worldwide challenge. In high speed production facilities response time between man and machine is of utmost importance when financial implications are taken into account. This dissertation contributes to improving the response time by making use of wireless notification between the machine and the maintenance technician when process faults occur. The tool used to achieve this is based on Android. Research is carried out on the latest Android technology while taking the safety aspects of a production environment into consideration. Research in designing a rule based intelligent system is established by using a tablet as the user interface for automatic notification and corrective action recommendations. Quick response is achieved by setting up a wireless network. As a result of designing a wireless intelligent maintenance tool, production downtime is improved. Management can recall all activities logged by the system for graphical representation.

  • Description: This study emerged from the high prevalence rate of HIV and AIDS infection among women in Sub-Saharan Africa, which has no exception to Namibia. Women have been vulnerable to HIV and AIDS let alone on sex related issues since the epidemic emerged, but not research has been done specifically to Okalongo women. The way in which women vulnerable to HIV and AIDS infection were explored by examined social and cultural identities that affect women’s sexual relations in negotiating sex and safe sex. Qualitative study on a sample of fifteen women was conducted in Okalongo. The purpose of this study was to investigate the conceptions and experiences of women in negotiating sex and safe sex with their husband and partners. Feminist theory guided the methodology and analysis of data. I assumed that gender roles andsexuality are socially constructed, shaped by religion, social, political, and economic influences and modified throughout life. Feminist theory assisted in documentary the ways in which the female’s gender and sexuality in Okalongo is shaped by cultural influences and by institutions that disadvantage female and other oppressed groups by silencing their voices. The feminist further guided the discussion of the contradicting messages about women’s sexuality and their experiences, as women complied, conformed and even colluded with their oppression. To address the issue under study, the primary analysis of data from the focus group discussion and individual interview were utilised. The following themes were the heart of analysis: Women Positionality, Normalisation and Compliance, Women Agency and Male Dominance Power, Women Perceptions of Risk, Sex Education in and out of school among Women.In this study the data suggested that women in Okalongo are more vulnerable to their lack of assertiveness, as they have difficult in developing an authoritative voice, they tend to be humble about their achievements and knowledge and to only assertively when concerned about others. The findings supported the literature that women’s vulnerability is strongly influenced and tied by broader forces present in the society. Women’s vulnerability is real and needs to be tackled for any progress to occur in the fight against AIDS. Until factors that constraints and enabling women agency to negotiate sex and safe sex acknowledged and addressed, women will continue to succumb to the HIV pandemic.

  • Description: South Africa is held up internationally as a beacon of good practice in terms of its efforts to promote gender equality and, the increased number of women in leadership positions in all spheres of government is testament to this. The representation of women in all spheres of government is advocated for and promoted by legislation and policies that aim to promote a gender focus on all government procedures and programmes. The purpose of this qualitative study was to explore the experiences of women leaders, including their reasons for maintaining leadership positions. It also addressed the challenges these women faced on their journeys and described their definitions of successful leadership based on their experiences. The qualitative nature of the research project made it possible to tell the stories of the participants’ experiences in order to understand their career progression and how it pertained to their concept of leadership. The three participants recruited for the study were women in positions of influence within their municipality including managers, directors, and executive directors. Purposeful sampling was used so that the chosen participants would have experience with the central phenomenon being studied. All of the women contacted to participate in this study readily agreed to share their experiences. There was some level of diversity regarding the age, ethnic backgrounds, and education level of the participants. Semi-structured personal interviews were conducted to collect the data. Open-ended questions were used so the responses of the participants could guide the development of themes and the direction of the study. Once the data were collected through recorded interviews, codes were assigned to sections of the text to help identify themes. A coding table was developed to illustrate how the themes for the discussion emerged from data obtained during the interviews. The stories of the participants were interwoven based on the themes and also analyzed in terms of the existing research. A discussion of the findings incorporated the literature and provided evidence of connected concepts. Strategies including inter-coder agreement, rich description, and clarification of biases were used to strengthen the study’s findings. Ethical issues were addressed throughout each phase of the study. All participants were asked to sign an informed consent form that outlined the procedures of the study. The identity of the participants was kept confidential through the use of pseudonyms.

  • Description: This thesis will discuss how the application of place theory might provide insight into how a selection of Xhosa-speaking people in a rural village (Ntloko), in the former Ciskei of the Eastern Cape, interact with and establish relationships with the local indigenous thicket forest (ihlathi). I am concerned with how these influence residents' perceptions and attitudes (relational epistemologies) towards this resource, and how these may (or may not) translate into conservation practices. I am also interested in how socio-political and economic changes have altered these people/place relations (including gender) and their corresponding cultural perceptions. It is argued that the local thicket forest's significance and importance moves beyond the economic and utilitarian value of its natural resources. The thicket plays an important part in local identity construction, due to both its socio-cultural significance and its role in local livelihoods. People form meaningful attachments and relationships (relational epistemologies ) with the thicket as a place, through their interactions with it. While this may or may not result in actions and attitudes in-line with the conservation agenda, it is shown that this relationship is necessary for a local concern and stake in the natural environment. Those who have no or minimal interaction, such as many of the young women of Ntloko, have no opportunity to forge a relationship with it. Ihlathi may be known through narrative, but not personal experience, and as such no significant attachments can be formed, and thus concern for its conservation status is irrelevant. It is clear that if you remove people from an environment, you remove the stake they hold in the environment in question, thereby disrupting the relationship, and alienating people from nature. While a relational epistemology may not equate to conservation practices, it does imply a stake or concern in the environment, and as such, may provide an opportunity for conservationists to work with local communities. Resistance to conservation and development projects that aim to exclude local interaction, and therefore relationships, with the environment, will always be strong when local identities are intricately tied to the places and experiences that form them. Threatening that relationship threatens local identities and the attachments that orient them.

Marred by the politics of separate but (un)equal treatment of its people, the country's past political system has had a damaging effect in all spheres, but specifically on that of the family. In the context of relationships, it is fair to say that the apartheid system was replicated in family law, with the Western 'white' monogamous marriage receiving the state's stamp of approval - leaving other relationships (customary, Muslim, homosexual, cohabiting etc) largely out in the cold.

  • Description: In this work, a comparative study of photodegradation of methyl orange, an azo dye, in homogeneous aqueous solution of a quarternized cationic zinc phthalocyanine and a heterogeneous catalytic system based on the same phthalocyanine anchored on polysulfone polymer fiber is presented. In both cases, conversion involved the azo bond of the dye with no detectable opening up of the aromatic benzene rings. The reaction kinetics in both cases were consistent with first order with the conversion occurring in the homogeneous system being faster than when the functionalized polymer fiber was used. The reaction products consisted of a coupling product as well as a series of oligopolymeric products.

  • Description: publisher version , The rapid expansion of social protection in the South provides a rich diversity of experiences and lessons on how best to reduce poverty and ultimately eradicate it. Knowledge on how best to ‘grow’ social assistance, understood as long-term institutions responsible for reducing and preventing poverty, is at a premium. This article examines the expansion of social assistance in Brazil and South Africa, two of the middle income countries widely perceived to have advanced furthest in ‘growing’ social protection. It examines three aspects: the primacy of politics in explaining the expansion of social protection and assistance, the tensions between path-dependence and innovation in terms of institutions and practices, and the poverty and inequality outcomes of social assistance expansion. The article concludes by drawing the main lessons for other developing countries.

“A road that may lead nowhere”: JM Coetzee, Tayeb Salih, and the Hospitality of Vagrant Writing

  • Authors: Marais, Mike

  • Description: In this article, I argue that Coetzee's writing, being alienated from history but unable to transcend it, is forced to treat its own representations with a measure of suspicion. By extension, the Coetzee text is always divided against itself. It is, in the idiom of hospitality, never quite at home with itself because it is aware that home is premised on exclusion, on the existence of an outsider, one for whom home is not a home.
