- Description: Fishers make an important contribution to the global economy and add value to a country’s gross domestic product. Their contribution is even more important in countries such as Namibia that rely heavily on the fishing industry as a source of income. The working conditions of fishers have recently come under scrutiny as a result of poor labour standards when compared to employees ashore. A background of the working conditions of fishers is provided illustrating the unique working conditions of the fishing industry. After that the international standards, namely those of the United Nations and the International Labour Organisation (hereinafter referred to as “the ILO”), are discussed and the challenges in the regulations of the condition of employment of fishers are pointed out. The ILO recently adopted the Work in Fishing Convention (hereinafter referred to as “the WIFC”) in 2007, which is the primary instrument applicable to fishers’ conditions of employment. Namibia has not ratified the Convention and, as a result, it has no legal obligation to comply with the standards it sets. The international standards were tested against the national legislation of Namibia. This was done to determine the extent of Namibia’s compliance with those standards. The dissertation revealed that, if Namibia were to immediately ratify the Convention it would not conform with the standards and, as a result, would be in breach of its international obligation. The dissertation takes a step further by comparing the approach taken in regulating the conditions of employment in Namibia to the approach taken in South Africa. The purpose of the comparison is to determine the lessons Namibia can learn, if any, to improve the regulation of the condition of employment for its fishers. The dissertation 7 reveals that there are lessons Namibia can learn from South Africa to improve the conditions of employment of the fishers. These lessons relate to introducing a bargaining council and, where necessary, statutory councils for the fishing industry. The introduction of a bargaining council and statutory councils would give organisations such as trade unions more power to negotiate a general standard across multiple sectors within the fishing industry. The standards that are negotiating could incorporate the standards provided in the WIFC even though Namibia has not ratified the convention.

- Description: The Department of Health is experiencing repeated negative press releases with the respect to the quality of service delivery in the Eastern Cape. The public sector is an entity that provides a unique service. This is made evident by the services provided such as provision of free health services for primary health care as well as free health services to children under six, disabled and senior citizens. The Eastern Cape Department of Health has developed service standards adopted in 2007 by the Eastern Cape Department of Health. This study aims to determine the casual effect of absenteeism and their relationship to poor service delivery. According to Makhubu (2006) many vacancies in the Eastern Cape Department of Health exist which result in service delivery problems. In terms of the second principle in the Batho Pele Principles the norms and standards which are service standards serves as a baseline where the Department of Public Service and Administration (2007) issued directive that the vacancy rate of any government department should range between ten and fifteen percent Makhubu (2006) further refers to the doctors/patient ratio as one is to three hundred patients (1:300), which is unhealthy and abnormal as the doctor/patient ration in terms of the Health Professional is one is to thirty (1:30). Such cases pose an opportunity to those employees who are within the service to absent themselves from such unhealthy situations and this behavior later result in the exodus (professional drainage) of employee. Schultz, Nel, Gerber, Hassbroek, Van Dyk and Werner (2001:582) define absenteeism as withdrawal of levels of productivity and collegial interaction for a given time to escape a perceived undesirable working environment. This behavior is disruptive to continuous organizational efficiency. Absenteeism is found in two forms that are avoidable and unavoidable. In the unavoidable forms of absenteeism, the situation in unplanned and is governed by external factors, thus it is beyond one’s control and has to be managed differently. Control of absenteeism can exercise by the immediate manager through the human resource section regarding the duration and terms of absence pertaining salary and terms of services.

- Description: The insight that the fossil fuel reserves are limited, together with concerns over security of supply (i.e. the oil crises), initiated the first raise of interest in biomass and all other renewable energy forms. However, the concern grew that global warming and the resulting climate change were enhanced by carbon dioxide (CO2) emissions resulting from fossil fuel consumption. Meanwhile, biomass energy is thought to account for 14–15percent of total world energy consumption. Hence, the exploitation and utilization of biomass energy are effective and necessary for relieving the pressures caused by environmental pollution and fossil fuel shortage (Lv et al., 2010). Recently, extensive research aimed at converting biomass to useful energy have been carried out, especially pyrolysis and gasification, which are particularly suitable for the effective and efficient utilization of biomass. Sugarcane bagasse is the main byproduct of sugarcane mill, ready available at the production site so that it may be a suitable raw material for the production of biofuels, chemicals, and electricity. Among the methods that have been previously studied, is this particular study we explore thermochemical process, gasification. The properties of sugarcane bagasse relevant to gasification are briefly reviewed. The compositions of the bagasse as a fuel are variable, especially with respect to inorganic constituents important to the critical problems of sintering, fouling and slagging. Alkali and alkaline earth metals, in combination with other fuel elements such as silica and sulfur, are responsible for many undesirable reactions in a gasifier system. The three sugarcane bagasse types namely washed, unwashed and the depithed sugarcane bagasse were subjected in different types of characterization to review and compare their characteristics for gasification. Ultimate analysis was used to determine the elemental compositions and this was helpful in estimating the energy input of the materials. Elemental compositions were determined with the CHNS analyzer which gave the percent compositions of each fuel in terms of Carbon, Hydrogen, Nitrogen, Sulphur as well as Oxygen (by difference) and the SEM/EDX which gave the elemental composition of the materials as can be viewed from the EDX. The proximate analysis which is the physical characterization of the materials was carried out to preview the behavior of the sugarcane bagasse when subjected into high temperatures as the gasification process uses very high temperatures. These were determined by the TGA and the volatile matter content; fixed carbon content, moisture content and ash content were extrapolated from the resulting thermogram. SEM images for surface structures of the bagasse and FTIR for the structural functionality and bonding structures. The characterization of the bagasse was conducted to compare their gasification properties.

- Description: The extensive amount of research conducted in the field of family violence internationally indicates that child abuse has a detrimental effect on both the physical and emotional development of children as well as having a profound effect on an individual’s psychological development and functioning in adult life. The aim of this research study was to describe the therapeutic process that unfolded with a seven year old allegedly abused female client within the framework of non-directive play therapy. The case was further contextualised utilising Erik Erikson’s theory of psychosocial development. This study served to broaden the body of psychotherapeutic knowledge by means of meaningful qualitative enquiry. The client was referred for therapy because of severe emotional and behavioural problems following the alleged sexual abuse. The client was seen over a period of eight months and this included 11 sessions of non-directive play therapy, three parent interviews and psychometric assessments conducted by a colleague. The case study method was utilised in this study. To achieve the aim of the research, the methodology of choice was the descriptive dialogic case study. A purposive sampling technique was used in the selection of the research subject for this study. The data collection and analysis were conducted according to Yin’s (1994) analytical generalisation, which consists of two main strategies: (a) using a theoretical framework as a guide to determine what data is relevant; and (b) developing a matrix as a descriptive framework for organising and integrating the data. Furthermore, the process of data analysis was aided by the use of guidelines proposed by Irving Alexander (1988) with Axline’s non-directive play therapy and Erikson’s theory of psychosocial development as the theoretical frameworks. The findings of this study suggest that plotting the play therapy sessions according to the framework of the four stages of play therapy was a particularly useful tool to monitor Michelle’s progression through the therapeutic process. This can be seen as a valuable application of a tool which can be used within the non-directive play therapy approach. Contextualising Michelle’s development according to the stages of Erikson’s theory of psychosocial development was also found to be a valuable endeavour. According to her chronological age, Michelle should have been in the fourth stage of industry versus inferiority, but in reality Michelle was still struggling to strike a healthy balance between the terms of conflict of trust versus mistrust issues of the first stage. From a therapeutic point, this was an important exercise as it helped to inform the therapist and consequently, the therapeutic process. This research undertaking can be recognised as a positive demonstration of the value of non-directive play therapy (Virginia Axline) and Erik Erikson’s theory of psychosocial development in the therapeutic process. In addition, this study has served to facilitate a more holistic understanding of the case study approach to research. Recommendations regarding future research undertakings that utilise the case study approach and methodology have been made. Key concepts: child abuse; family violence; non-directive play therapy; Erik Erikson’s theory of psychosocial development; analytical generalisation; case study research.

- Description: This study examines the lifestyle decisions of people who are diagnosed with HIV/AIDS in King Williams Town, Eastern Cape. The study was motivated by the ever growing number of people who are now living with HIV/AIDS. Therefore the researcher intended to examine their decisions regarding sexual choices, reproductive health, diet, physical fitness and their coping strategies. The study found that there is very low uptake of Voluntary Counseling and Testing (VCT). Most people only get tested if they are compelled by other factors, like illness and pregnancy. It also found that HIV positive people continue to engage in risky sexual behaviour regardless of their positive status. In addition it also found that HIV positive status does not affect sexual activity and social support from family and friends is a very important factor that is helping the respondents to cope with HIV diagnosis.

- Description: The purpose of this project was to investigate the role of melatonin in the pathophysiology of anxiety in humans. The literature study confirmed the intimate relationship between serotonin and melatonin. Melatonin is not only able to act as an agonist (in physiological concentrations) and an antagonist (at higher concentrations) on serotonin receptors but via control of brain pyridoxal kinase activity might have an effect on GABA, serotonin, dopamine and norepinephrine synthesis. A clinical trial to investigate melatonin's effect on anxiety in humans was conducted as a pilot study. Thirty patients complaining of anxiety participated in a liN of 1" double blind placebo controlled trial. During the experiment each subject was thus exposed to melatonin and a placebo for a week at a time on two occasions. During the first phase of the experiment, (Pair '1) patients showed a statistically significant reduction in their anxiety levels during the first period (P1P1), which was not the case during the second period (P1P2). The improvement however continued during the second phase of the experiment (Pair 2) so that there was also a statistically significant improvement during P 2 P 2 (Period 2 / Pair 2) when placebo was administered. It could not conclusively be shown that melatonin was responsible for the improvement in the patients' anxiety. The explanation for these results suggests thelt the improvement was due to a: 1) placebo effect throughout, 2) psychotherapeutic effect due to contact with a clinician, 3) melatonin induced phase shift in the patient's endogenous melatonin response curve, 4) combination of all 3 options. This pilot study lays the groundwork for a much more exhaustive study in which the melatonin of the patients is determined before melatonin is administered, the role of the clinician is clarified and the most appropriate time for melatonin administration is sought .

- Description: The Lower Permian Ecca Group formations of the Karoo Basin of South Africa have recently been identified as a target for shale gas exploration. These units, named the Prince Albert, Whitehill and Collingham formations, comprise organic-rich shales with occasional associated carbonate deposits, and siliciclastic facies. Mineralogical and geochemical investigations were conducted into carbonaceous shales and associated sedimentary rocks in the Jansenville area of the southern Karoo Basin with the ultimate aim to decipher the paleoenvironment and post-depositional conditions of these shales and their associated features such as prominent intra-formational carbonate deposits. Sediments of the main Karoo Basin were deposited from ~350 Ma to ~182 Ma, the end of sedimentation being marked by eruption of basaltic lava. This period, which began with the Dwyka continental glaciation, included tectonism of the Cape Fold Belt, the end-Permian mass extinction at ~250 Ma, and major intrusion of dolerite associated with the lavas of the Karoo Large Igneous Province. Subsequent to this, the basin experienced faulting associated with Gondwana breakup, uplift and intrusion of small volume kimberlite and melilite magmas, and erosion resulting in formation of a major escarpment. Each episode was imprinted upon the Karoo rocks and to a greater or lesser extent erases the signature of older episodes. To decipher the depositional paleoenvironment and post-depositional conditions of the black shales and the dolomite concretions posed a challenge due to deformation, orogeny, metamorphism, and weathering and erosion. Therefore, deep borehole core-logging and sampling was generally preferred over surface fieldwork, and trace elements backed up by scanning electron microscopy-based petrography was the method most relied upon to decipher the redox conditions of the black shales and the intra-formational carbonates. Relevant sections from three SOEKOR boreholes SP1/69, AB1/65 and QU1/65 were logged and carbonate concretions localities studied in four field locations. Samples collected from the core and field localities were prepared for thin section optical, SEM petrographical analysis, mineral identification, modal estimation by XRD, major, and trace element analysis by XRF and Laser Ablation-ICPMS, and acid leaching of a sample subset to determine the degree of pyritization (DOP). Logging of the SOEKOR boreholes indicates that in the western part of the basin all three lower Ecca formations, namely the Prince Albert, Whitehill and Collingham, overlie the tillites of the Dwyka Group, whereas near East London only the Whitehill Formation is present. Dwyka diamictites occur in all the studied boreholes overlying the crystalline basement in AB 1/65 and QU 1/65 boreholes whereas in the SP 1/69 the tillites rest above the quartzite of Witteberg Group of the Cape Supergroup. The shale consists of discontinuous, wavy and straight parallel laminae. Parallel, discontinuous and elongate micro-lenses of very fine-grained quartz are diagnostic and suggest late-stage silicification. Thin laminae of black shale are interlaminated with grey clay. The black shales are composed of quartz and clay minerals (illite and chlorite) as the major crystalline minerals with minor quantities of sulphides and heavy minerals. Organic matter occurs as unstructured, anhedral patches of amorphous material. It contains abundant small (~10nm) and less common larger (~100 nm) pores of subsphaeroidal shape. Carbonates occur as cementation and concretions. Heavy minerals identified by SEM include detrital zircon, thorite, titanite, authigenic fluorite, galena, sphene, and sphalerite and apatite, monazite and epidote-group minerals that appear to be of later stage metamorphic origin, some a product of hydrothermal feldspar alteration. Zircon and monazite show evidence of partial corrosion and/or new overgrowth. Titanite occurs in greater abundance in the SP1/69 section than other boreholes, where it exhibits a porphyroblastic texture suggesting secondary growth. These features all suggest modification of detrital minerals by metamorphic fluids and therefore some possible modification of bulk geochemical composition. Pyrite is abundant, commonly occurring as framboidal and occasional euhedral grains. Pyrite-bearing, calcite veins are common in the Whitehill Formation. Some pyrite is metamorphosed to pyrrhotite in the shales adjacent to dolerite intrusions. The carbonate deposits in the lower Ecca occur mostly as large concretions of 0.5-2.5 m in diameter at intensely faulted areas, and as laterally continuous beds at less intensely faulted areas. They consist of dominant dolomite with calcite (differentiated by thin section staining) and minor associated quartz veins, and appear to have formed in an early diagenetic stage of the black shale. Five different dolomite-rock textures were identified indicating varying crystal growth conditions. Calcite cementation types accompany these dolomite textures. The major types include mosaic, sparry and bladed/prismatic calcite cement. Calcite occurs mainly as cement in pores and grain replacement, as well as crudely radial septerian veins. XRD indicates that the carbonate concretions are made up of more than 90% dolomite, especially within the intensely folded areas. The remaining 10% consist of post-depositional quartz veins and secondary calcite associated with the quartz veins. In one locality (VAAL) the carbonate samples are dominates by bladed/prismatic calcite. The black shales in this study have similar geochemical signature to previously analysed samples from the Karoo Basin and to black shales worldwide. The geochemical signature results from the combined input of detrital sedimentary materials as well as enrichment or depletions acquired from pore water, biological activity and during diagenesis. Positive correlation of K2O, Na2O with Al2O3 suggests control by the detrital contribution. CaO and P2O5, have a negative correlation with Al2O3 suggesting a biogenic source. Elemental ratios suggest that the sediments derive from felsic source rock, most likely Cape Supergroup and underlying crystalline basement. These shales exhibit different degrees of trace-element enrichment relative to global average shale, the approximate order being Pb> V> Zn> Cr> Cu> Co > Ni. Assessment of selected trace elements, V/(V+Ni), V/Cr, Ni/Co and EF Mn ratios describes the paleoenvironment of these sediments to have been partially oxygenated before sulphate reduction interface. The pyrite size distribution, DOP, Fe and S correlation points to an organic matter limited environment, where the main sulphur sink is pyrite rather than organic matter. The DOP and Fe/Al indicated that the sediments became anoxic at the sediment-water interface (early diagenetic stages). V/Cr assessment of the dolomite concretions suggested partially oxygenated environment corresponding to the black shale deposition. The occurrence of concretions at the base of the Whitehill Formation, which has the highest TOC content of 14% compared to other associated formations, is evidence that organic matter preservation was important to their origins. The parameters used here to assess the redox conditions of the black shales and the dolomite concretions in this region of the Karoo Basin suggest a normal marine redox environment, rather than the anoxic Black Sea-type environment. The conditions that affected the lower Ecca formations varied from semi-oxygenated to oxygen depletion environment. The oxygen depletion environment occurred during the deposition of the Whitehill Formation of which organic matter preservation was favoured..

- Description: The purpose of this research was to investigate the reasons for non-adherence to the ISP and to measure the current level of adherence to the ISP. The research revealed that non adherence to the ISP is caused by lack of training or awareness, and through non-communication of the ISP to employees. The study was conducted at Capricorn District Municipality, Polokwane Local Municipality, Molemole Local Municipality and Blouberg Local Municipality. A web-based questionnaire (QuestionPro) was developed and it was directed to every official who uses or interacts with municipal information, to quantify the level of adherence to ISP by employees. An email with the questionnaire link administered by www.questionpro.com was then sent to the population of 152 employees. Presently ISP adherence is one of the key concerns that are faced by organisations. Employees are perceived as one of the reasons that there are security breaches within organisations; hence, it is of paramount importance that these security breaches are noticed, as well as technical matters. Most researchers have reasoned that non-adherence to ISP is one of the major challenges faced by organisations. The non-adherence to ISP will lead to potential information security threats and unauthorised access to information that might compromise municipal business operations. The Information Security Officer together with the help of management must educate employees regarding the value of IS and why it is crucial to adhere to these policies. The proposed strategy summarises the various concepts required in the promotion of awareness and adherence to an effective ISP. Ultimately, this research study concludes that if management continually trains employees, raising awareness about ISP and monitoring their adherence to ISP, this should increase the adherence level.

- Description: publisher version , A mantra of social science declares a fundamental divide between the quantitative and the qualitative that involves more than methods. According to this depiction, the two methodologies are intrinsically associated with a range of ontological, epistemological, political and moral stances. Each of these constellations of stances is strongly integrated, such that choice of method is held to involve a series of associated choices. Each constellation is also strongly opposed to the other, along axes labelled positivism/constructivism, scientism/humanism, conservative/critical, old/new, among others. These ‘binary constellations’ (Maton 2014b: 148-70) offer a forced choice between two tightly-knit sets of practices that are portrayed as jointly exhaustive and mutually exclusive. So widespread is this methodological binarism that many scholars ‘are left with the impression that they have to pledge allegiance to one research school of thought or the other’ (Johnson and Onwuegbuzie 2004: 14). A competing mantra disclaims this divide. Distinctions underpinning the picture of binary constellations have been regularly dissolved. Arguments that one deals with numbers, the other with words, one studies behaviour, the other reveals meanings, one is hypothetico-deductive, the other inductive, one enables generalization, the other explores singular depth, among others, have been repeatedly undermined (e.g. Hammersley 1992). Indeed, the death of the divide is frequently declared. Calls for ‘transcending’ (Salomon 1991) or ‘getting over’ (Howe 1992) the quantitative-qualitative debate and arguments for mixed-methods research (Brannen 2005; Johnson and Onwuegbuzie 2004) are recurrent. These calls highlight how the methodologies offer complementary insights for research and demonstrate that eschewing either methodology on principle is unnecessarily renouncing potential explanatory power. However, the call to mixed-methods research remains more breached than honoured. Methodological monotheism remains dominant – studies of education and society typically adopt either quantitative or qualitative methods. As we shall discuss, the former is typically associated with the influence of psychology and the latter is often claimed as emblematic of sociology. Studies utilizing the sociological frameworks on which Legitimation Code Theory (LCT) builds have echoed this pattern by overwhelmingly adopting qualitative methods. Accordingly, Part I of this volume begins by exploring how LCT concepts can be enacted in qualitative research (Chapter 2). However, LCT is not limited to one methodology and a growing body of mixed-methods research is engaging with both qualitative and quantitative data. In this chapter we illustrate how this research works and the gains it offers. For resolutely qualitative researchers, the prospect of reading anything quantitative, even in mixed-methods research, may be unenticing. However, it would be a mistake to pass over this chapter, for several reasons. First, we offer insights into research practice that might surprise such scholars. As Bourdieu argued, ‘methodological indictments are too often no more than a disguised way of making a virtue out of necessity, of feigning to dismiss, to ignore in an active way, what one is ignorant of in fact’ (Bourdieu and Wacquant 1992: 226). Our aim is to contribute towards removing this reason for one-sidedness. We show, for example, how quantitative methods confound their common portrayal as neat, straightforward and procedural; they are complex and involved and require craft work and judgement. Our focus is, therefore, more practical than metaphysical. We shall not enter seemingly endless debates over whether the ‘quantitative-qualitative divide’ refers to paradigms, epistemologies or methods and whether these are complementary or incommensurable. Rather, we discuss the development of an instrument for enacting LCT concepts in quantitative methods and ground this account in real examples of mixed-methods research. Specifically, we trace the evolution of an instrument for embedding specialization codes within questionnaires through its creation for research into school music and then its development within studies of educational technology. Given that mathematics can be off-putting to the noviciate, we minimize discussion of statistics and explain measures in lay terms. Second, this is much more than a story of quantitative methods. The evolution of the instrument both shaped qualitative methods and was shaped by the data they generated, offering insights into how qualitative research can more fully engage with LCT. Its development also involved intimate dialogue with theory that shed fresh light on LCT itself, making explicit the ‘gaze’ embodied by the framework (Chapter 1, this volume). We shall highlight wider lessons learned about the craft of enacting LCT in research, lessons of direct relevance for studies using any methods. Third, we shall illustrate the explanatory power offered by using quantitative and qualitative methods together, such as providing a robust basis for detailed findings, identifying wider-scale trends typically inaccessible to qualitative methods that provide a context for their data, and facilitating knowledge-building through greater replicability across contexts and over time. For example, the technology studies built directly on the music studies to cumulatively develop the instrument and generated probably the largest data set in code sociology: 97,386 responses (83,937 student and 13,449 staff surveys) on the organizing principles of academic subjects, alongside 20 in-depth qualitative case studies of secondary schools. This offers a foundation of substantial breadth and depth for making claims about knowledge practices across the disciplinary map and a firm basis on which future research into disciplinary differences can build. Moreover, the quantitative instrument itself can be adopted or adapted in new studies, further enabling cumulative knowledge-building. Given these substantive, methodological and theoretical gains, it is perhaps surprising there exists any temptation to skip past discussion of mixed-methods research. This reflects the methodological character of the fields in which LCT emerged. We thus begin by briefly illustrating how the sociological frameworks on which the theory builds have become distanced from quantitative methods.

Rather, we discuss the development of an instrument for enacting LCT concepts in quantitative methods and ground this account in real examples of mixed-methods research. Specifically, we trace the evolution of an instrument for embedding specialization codes within questionnaires through its creation for research into school music and then its development within studies of educational technology. Given that mathematics can be off-putting to the noviciate, we minimize discussion of statistics and explain measures in lay terms. Second, this is much more than a story of quantitative methods. The evolution of the instrument both shaped qualitative methods and was shaped by the data they generated, offering insights into how qualitative research can more fully engage with LCT. Its development also involved intimate dialogue with theory that shed fresh light on LCT itself, making explicit the ‘gaze’ embodied by the framework (Chapter 1, this volume). We shall highlight wider lessons learned about the craft of enacting LCT in research, lessons of direct relevance for studies using any methods. Third, we shall illustrate the explanatory power offered by using quantitative and qualitative methods together, such as providing a robust basis for detailed findings, identifying wider-scale trends typically inaccessible to qualitative methods that provide a context for their data, and facilitating knowledge-building through greater replicability across contexts and over time. For example, the technology studies built directly on the music studies to cumulatively develop the instrument and generated probably the largest data set in code sociology: 97,386 responses (83,937 student and 13,449 staff surveys) on the organizing principles of academic subjects, alongside 20 in-depth qualitative case studies of secondary schools. This offers a foundation of substantial breadth and depth for making claims about knowledge practices across the disciplinary map and a firm basis on which future research into disciplinary differences can build. Moreover, the quantitative instrument itself can be adopted or adapted in new studies, further enabling cumulative knowledge-building. Given these substantive, methodological and theoretical gains, it is perhaps surprising there exists any temptation to skip past discussion of mixed-methods research. This reflects the methodological character of the fields in which LCT emerged. We thus begin by briefly illustrating how the sociological frameworks on which the theory builds have become distanced from quantitative methods.

- Description: Information Communication Technology (ICT) is becoming popular especially within a university campus setting not only as a learning tool but also for the purpose of communication. Internationally there is an acknowledgement of the popularity of ICT in delivering mental health services. This study is built on that premise which indicates that ICT could serve as a viable tool for counselling interventions within a university setting. However, limited research has been done in this area and conflicting results have been reported especially related to gender. This study therefore aimed at exploring the intentions and attitudes of male and female students towards using ICT for counselling at a South African university. A quantitative research approach was employed to collect and analyze data. Data was collected amongst students using self-administered questionnaires with a sample of 266 (N = 266) respondents. Descriptive and inferential statistics were employed. The main findings of the study indicate that students have an intention to seek psychological help through the use of ICT counselling, which consequently positively influenced attitudes towards the utilization of ICT counselling. Results further indicate that gender and age differences amongst university students is significantly related to the intention to use ICT counselling. The information generated from this study has contributed to the limited body of literature on ICT in counselling psychology, more specifically in a university setting in South Africa. Overall, it encourages critical reflection on modern psychological practice to meet student’s needs.

- Description: Child sex tourism is tourism organised with the primary purpose of facilitating a commercial sexual relationship with a child. It involves a segment of the local child sex industry that is directly connected to both an international and domestic tourist market. The increase of tourism has brought with it complications in that tourism is being used as a means for sex tourists to initiate contact with children. Aside from child sex tourists who are paedophiles, there are those who engage in the opportunistic exploitation of children while travelling on business or for other reasons. There are a number of social and economic factors leading to child sex tourism and the effect is that child victims are exposed to immediate harm, irreversible damage and even death. As South Africa's tourism industry expands into one of the country’s top earners of foreign currency, it is unfortunate to note that its child sex tourist trade is also on the increase. Reports show that sex tours are as easily organised as wine route tours in Cape Town. Commercial sexual exploitation of children is prevalent in South Africa and has become more organised in recent years. A comprehensive response to the problem is essential to ensure that South Africa does not become a “safe haven” for child sex tourists. Effective laws at home and the extraterritorial application of these laws to prosecute South African nationals for crimes committed abroad are imperative. Significant steps are being taken both nationally and internationally to target child sex tourism. South Africa has ratified several international instruments on children’s rights, trafficking in persons, child labour, and discrimination against women and young girls, all of which relate to child sex tourism. In doing so, South Africa has made an international commitment to uphold the provisions of these instruments and give effect to them. South Africa is therefore under an international obligation to create the necessary structures and apply mechanisms and resources to combat child sex tourism.

- Description: The one-pot synthesis of silver nanoparticles (AgNPs) using the medium-polar extract of Desmodium adscendens (Sw.) DC. is presented here as an alternative synthesis of metal NPs. Characterisation of the formed NPs showed polydispersed AgNPs ranging from 15 to 100 nm where the concentration of metal ions was found to play a role in the size and shape of the prepared NPs. It could be established that the flavonoids, saponins, and alkaloids present in the extract acted as both reducing and stabilising agents during the formation of the capped metal NPs. This means of NP synthesis was also employed during the in situ immobilisation of AgNPs on gauze and plaster. An evaluation of the antibacterial activity of the medium-polar D. adscendens extract, AgNPs suspended in solution, and the immobilised AgNPs against Staphylococcus aureus (ATCC 25923), Bacillus cereus (ATCC 11778), and Escherichia coli (ATCC 25922) showed high efficacy against the latter in particular. This suggests that gauze, dilute silver nitrate solutions, and D. adscendens extract could be used successfully in the simple in situ preparation of effective antibacterial wound dressings.
