- Description: Patients with drug resistant tuberculosis (TB) are treated with multiple antibiotics including moxifloxacin, linezolid, and meropenem, which puts them at greater risk for colonisation by multi-drug resistant (MDR) bacteria. The objectives of this study were to: (i) assess the antimicrobial prescribing patterns practiced within the hospital by retrospective patient file review; (ii) determine the spectrum of bacterial colonisation in TB patients upon admission and during hospitalisation; (iii) identify bacterial isolates and evaluate antimicrobial susceptibility profiles; (iv) detect antimicrobial resistance genes in the bacterial isolates by PCR and DNA sequencing; and (v) investigate genetic relatedness of Klebsiella pneumoniae isolates using Multi Locus Sequence Typing. Nasal, groin and rectal swabs [for the detection of extended spectrum beta lactamases (EBSLs), carbapenem-resistant Enterobacteriaceae (CRE), vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA)] were analysed from a cohort of patients (n=37) admitted either from the community (n = 28) or from other healthcare facilities (n=9) to a TB hospital. Swab samples were collected at admission and at four week intervals thereafter during hospitalization. Identification and antimicrobial susceptibility testing of bacterial isolates (n=62) were determined at the National Health Laboratory Services (NHLS) by the VITEK-MS and Vitek 2 systems respectively. Additional antimicrobial susceptibility testing was conducted by Sensititre Gram Negative Xtra (GNFX2) MIC plates. PCR and DNA sequencing were used for detection of resistance genes. Patients (n=13/37; 35%) were colonized by MDR bacteria (ESBLs [n=11], MRSA [n=2]) on admission. Colonization rates were lower in patients admitted from the community (9/28; 32%) compared to those transferred from other healthcare facilities (4/9; 44%). All admitted patients who did not exhibit colonization at baseline and who were resident within the hospital for longer than 4 weeks (17/37; 46% of total patients) became colonised by an ESBL-producing Enterobacteriaceae species. No patients acquired MRSA during hospitalisation. Among ESBL Enterobacteriaceae, Escherichia coli (41/62; 66%) and K. pneumoniae [14/62; 23%]) predominated. Nineteen percent (7/37) of patients demised during their hospitalization. Both the Vitek system and Sensititre Gram Negative Xtra (GNFX2) MIC plates susceptibilities were similar for most antimicrobials, however there were discrepancies for tigecycline susceptibility profiles. A high number of isolates exhibited resistance to aminoglycosides and fluoroquinolones. Genes encoding for ESBLs (CTX-M-14, CTX-M-15, SHV-28, OXA-1, and OXY-2-9) were detected among ESBL Enterobacteriaceae. Two Enterobacteriaceae isolates with reduced carbapenem susceptibility did not contain carbapenemase-encoding genes. MLST revealed unique sequence types and genetic diversity among the K. pneumoniae isolates from hospitalised patients. However, the source and colonization routes of these isolates could not be determined, which requires further investigation. This study provides insight into the spectrum of bacterial pathogen colonisation in hospitalised TB patients and suggests a review of infection control programs and practices at the TB hospital.

- Description: Numerous studies have investigated FDI and the possible benefits for African countries in terms of job creation opportunities, technology transfers, growth and development. Despite these potential benefits, FDI also has its negative effects on the host country in terms of market dominance, profit repatriation and loss of tax revenue if tax incentives are offered. In an effort to attract more FDI, host countries have undertaken various policy incentives to attract foreign investors. This study examines the trends and determinants of FDI flows to South Africa and other African countries. The period chosen for this study is from 1990- 2016. The study commences with a background study of FDI and GDP. Various literature offerings and different schools of thought with regard to FDI are also deliberated. To offer a better understanding of the relationship between FDI and GDP, econometric estimation was employed. The econometric estimation methods employed were, Unit Root, Johansen Cointegration, Vector Error Correction (VECM), Impulse Response Test, Variance Decomposition and the Granger Causality Test. Based on Granger causality test it can be concluded that South Africa’s economic growth attracts FDI and not vice versa. South Africa must therefore focus on growing its economy to attract more FDI.

- Description: This research used three theories to develop a theoretical framework that investigated the role of family structures and financial socialisation in influencing students’ levels of financial knowledge, attitudes, self-efficacy and behaviour (financial capabilities). It also examined the mediating role of family financial situation in the relationship between the family structure and the mechanisms of financial socialisation. The theories of consumer socialisation, family financial socialisation and family structure model, guided the development of a proposed theoretical framework and development of five major hypotheses. To answer the research questions of the study and test the hypotheses, this study followed a quantitative survey research design. Undergraduate students in the Faculty of Business and Economic Sciences completed 350 questionnaires. Using exploratory factor analyses results, the theoretical framework was updated, and statistical relationships tested. Simple regression analysis results showed that students who were born or raised in an intact family structure reported more financial socialisation in terms of the mechanisms of financial socialisation than students who were born or raised in non-intact family structures. Simple regression results showed that intact family structures had positive significant relationships with four of the six components of the mechanisms of financial socialisation. Furthermore, intact family structures had negative significant relationships with two components of the mechanisms of financial socialisation. Multiple regression results showed four components of the mechanisms of financial socialisation (teaching and monitoring, reinforcement of financial behaviour, modelling of financial behaviour and financial conflict) had positive significant relationships with financial capabilities. The components of financial socialisation agents (peers and media) had positive significant relationships with three components of financial capabilities (financial behaviour, money is respect and freedom, and money is good). In addition, family financial situation partially mediated the relationship between intact family structure and three components of the mechanisms of financial socialisation, namely, parental teaching and monitoring, modelling of financial behaviour and parental relationship. Furthermore, family financial situation perfectly mediated the relationship between intact family structures and one component of the mechanisms of financial socialisation (reinforcement of financial behaviour). Three components of the mechanisms of financial socialisation (parental teaching and monitoring, reinforcement of financial behaviour and modelling of financial behaviour) also perfectly mediated the relationship between intact family structure and one component of financial capabilities, namely, financial behaviour. Similarly, one component of the mechanisms of financial socialisation (parental teaching and monitoring) also perfectly mediated the relationship between intact family structure and one component of financial capabilities (financial self-efficacy). These results assisted in the development of a new empirically tested model to investigate the role of family structure and financial socialisation in influencing students’ financial capabilities. This study showed that family structures was an important variable that should not be excluded in financial planning as it influenced all the components of the mechanisms of financial socialisation. Financial socialisation agents also had an influence on financial capabilities and, thus, the parental financial socialisation should not be investigated in isolation. It was also important to identify the mechanisms of financial socialisation as seen in this study, as the components of the mechanisms had different influences on students’ financial capabilities. For this study, parental teaching and monitoring, reinforcement of financial behaviour and modelling of financial behaviour proved to be the most important components of the mechanisms of financial socialisation, which ultimately influenced students’ financial capabilities. This study has proved that family structures and financial socialisation influence the financial capabilities of students. To improve financial capabilities of students, parents should increase their level of modelling of financial behaviour and decrease the level of secrecy about money in the household. Parents should also instill positive financial attitudes in students, monitor their financial behaviour, and reinforce positive financial behaviour. This study contributes to the much-needed body of knowledge in financial planning by showing through empirical results that family structure has an influence on the components of the factor mechanisms of financial socialisation, and the factor financial capabilities. As little information exists to explain these relationships, this study makes a valuable contribution to new knowledge in this area.

- Description: The aim of the research study was to investigate the experiences of secondary traumatic stress among social workers who deal with traumatised populations in the Buffalo City Municipality in the province of the Eastern Cape in South Africa. Qualitative research methods were employed to collect data from thirty participants; twenty were interviewed and 10 participated in a focus group discussion. The most significant finding of this study was that there is a high rate of secondary traumatic stress among social workers, particularly among those who practice in nongovernmental organisations (NGOs), especially those social workers who work with children. The intensity of secondary traumatic stress among social workers appears to be growing steadily, owing to either inadequate or a complete lack of supervision and support on the part of the agencies concerned. The study concludes that social workers are highly at risk of experiencing secondary traumatic stress. The study therefore recommends that policies that are there to protect social workers should be implemented and institutions of higher learning which educate and train social workers need to implement courses in their syllabuses which prepare students for the stresses which they will inevitably encounter while working in the field of social work, particularly secondary traumatic stress.

- Description: The study addresses the nature of Colombian sustainable social development and the internationalisation of higher education (iHE). This intersection is analysed within various theoretical paradigms surrounding social sustainable development and the internationalisation of higher education. This study aims at reviewing the activities of Higher Education Institutions (HEIs) which focus on internationalisation. The analysis focuses on the manner in which HEIs in Colombia approach internationalisation vis-à-vis social sustainable development, and emphasis is made on knowledge transfer, research and community engagement. Using the theories of sustainable development, the iHE, in terms of practises and policies, are assessed. Within a mixed-methods approach, data gathered from Colombian university heads (16 presidents and vice-presidents) and 133 individuals responsible for internationalisation affairs is analysed. Concurrent triangulation is used to help introduce a series of themes and sub-themes derived from the qualitative and quantitative information. Within a social constructionist framework, this study has a twofold purpose. On the one hand, it is sought to identify and understand the challenges for Colombia’s academic internationalisation; on the other, an in-depth approach is presented in relation to the way different stakeholders perceive the society-HE internationalisation nexus. The major findings of the study indicate that there is a need to clarify and revise Colombia’s Higher Education policy to address both the education needs of the society and its social development requirements. It was also found that higher education internationalisation could act as an important agent of social change.

- Description: In recent years, there has been an increasing focus on new sources of taxation, including wealth tax. In South Africa, two phenomena have driven the focus on wealth tax. Firstly, the need for additional tax revenue to fund an ongoing and growing budget deficit, exacerbated by a prolonged period of low economic growth, rising government debt and a very small base of individual taxpayers. Secondly, the fact that South Africa has one of the most unequal societies in the world. The dual demands of increased tax revenue and economic inequality have converged around wealth tax as a possible panacea to both problems. Although South Africa has a long history of wealth transfer tax in the form of estate duty and donations tax, there has never been a tax on the net wealth holdings of individuals during their lifetime. Internationally, numerous countries have used wealth tax in various forms, including inheritance tax, gift tax, recurrent wealth tax and non-recurrent wealth tax. This study examines some of the international experiences with these three categories of wealth tax, seeking lessons and experiences that can inform the debate around the viability of a new wealth tax in South Africa.

- Description: In a world of economic uncertainty and manifold social problems, South Africa has its own unique challenges of low economic growth, persistent budget deficits that produce increasing government debt and the highest level of economic inequality in the world. The history of injustice and economic marginalisation and the failure of the economy to provide inclusive growth drives an urgent need to address economic inequality through tax policy, placing ever more focus on wealth taxes as a possible solution. There is a hope is that taxing the wealthy may provide the opportunity to redistribute desperately-needed resources to those denied the opportunity to build wealth and who are trapped in the cycle of poverty. Yet, as appealing as a new wealth tax may seem, the introduction of such a tax carries with it a range of risks, not all of which are known. Of great concern is the possible effect on the economy, which, in its vulnerable state, cannot afford any loss of capital and investment. Very little research has been done on wealth tax in the South African context and there is a dearth of literature focusing on the views and perceptions of the wealthy individuals themselves. This qualitative study investigates the merits and disadvantages of a new wealth tax and seeks to identify any unintended consequences that could result from the implementation of a new wealth tax in South Africa, drawing from historical and international experience and primary data obtained from interviews with individuals likely to be affected by such a tax. Having explored the literature and international experiences with wealth tax and having probed the thinking of wealthy individuals who would be the payers of a wealth tax, the study finds that a new wealth tax may contribute towards the progressivity of the tax system, but it is doubtful whether such a tax would provide a sustainable revenue stream that would be sufficient to address economic inequality and there is a risk of causing harm to the economy. Recognising that the motivation for wealth taxes is often driven more by political argument and public perception than by rational quantitative analysis, the study also anticipates the introduction of a new wealth tax and suggests guidelines for the design of such a tax within the framework for evaluating a good tax system. This study informs the debate on wealth taxes in South Africa and contributes to the design of such a tax, should it be implemented.

- Description: Fisheries managers are increasingly promoting catch and release (C&R) as a means to manage recreational fish stocks. Several commonly used output regulations, including bag and size limits, require the mandatory release of captured fishes by anglers. In addition to mandatory C&R, conservation-conscious anglers have adopted voluntary C&R behaviour as a result of the noticeable declines in the populations of many fishery species and this behaviour is becoming increasingly popular among recreational anglers (Cooke et al. 2013a). The combination of mandatory and voluntary C&R behaviour is substantial, as Raby et al. (2014) estimated that 60% of fish captured in global recreational fisheries are released. In South Africa, Cowley et al. (2013) found that a large proportion (mean 74% [SD 7.3]) of the five most-dominant fishery species captured in the Sundays Estuary recreational fishery were released.

- Description: Because the Anthropocene by definition is an epoch during which environmental change is largely anthropogenic and driven by social, economic, psychological and political forces, environmental social scientists can effectively analyse human behaviour and knowledge systems in this context. In this subject review, we summarize key ways in which the environmental social sciences can better inform fisheries management policy and practice and marine conservation in the Anthropocene. We argue that environmental social scientists are particularly well positioned to synergize research to fill the gaps between: (1) local behaviours/needs/worldviews and marine resource management and biological conservation concerns; and (2) large-scale drivers of planetary environmental change (globalization, affluence, technological change, etc.) and local cognitive, socioeconomic, cultural and historical processes that shape human behaviour in the marine environment. To illustrate this, we synthesize the roles of various environmental social science disciplines in better understanding the interaction between humans and tropical marine ecosystems in developing nations where issues arising from human–coastal interactions are particularly pronounced. We focus on: (1) the application of the environmental social sciences in marine resource management and conservation; (2) the development of ‘new’ socially equitable marine conservation; (3) repopulating the seascape; (4) incorporating multi-scale dynamics of marine social–ecological systems; and (5) envisioning the future of marine resource management and conservation for producing policies and projects for comprehensive and successful resource management and conservation in the Anthropocene.

- Description: Across the globe, many coastal communities rely on marine resources for their food security (FS), income and livelihoods and with predicted trends in human populations, the number of people reliant on these resources is likely to increase (FAO, 2012). However, the effects of climate change including increased variability are already being experienced by coastal communities and appear to be accelerating (Doney et al., 2012). Depending on a range of factors, including location, these changes are having mild to severe impacts on communities both in direct and indirect ways (Miller et al., 2010). Communities in coastal areas, for instance, are particularly at risk due to sea level rise but also through their dependence on marine resources that are impacted by multiple climate change pressures. A change in the availability and condition of marine resources has consequences on the livelihoods of fishing populations or those who depend directly on fishing as a source of food (Badjeck, Allison, Halls, & Dulvy, 2010).

- Description: Local and indigenous knowledge is being transformed globally, particularly being eroded when pertaining to ecology. In many parts of the world, rural and indigenous communities are facing tremendous cultural, economic and environmental changes, which contribute to weaken their local knowledge base. In the face of profound and ongoing environmental changes, both cultural and biological diversity are likely to be severely impacted as well as local resilience capacities from this loss. In this global literature review, we analyse the drivers of various types of local and indigenous ecological knowledge transformation and assess the directionality of the reported change. Results of this analysis show a global impoverishment of local and indigenous knowledge with 77% of papers reporting the loss of knowledge driven by globalization, modernization, and market integration. The recording of this loss, however, is not symmetrical, with losses being recorded more strongly in medicinal and ethnobotanical knowledge. Persistence of knowledge (15% of the studies) occurred in studies where traditional practices were being maintained consiously and where hybrid knowledge was being produced as a resut of certain types of incentives created by economic development. This review provides some insights into local and indigenous ecological knowledge change, its causes and implications, and recommends venues for the development of replicable and comparative research. The larger implication of these results is that because of the interconnection between cultural and biological diversity, the loss of local and indigenous knowledge is likely to critically threaten effective conservation of biodiversity, particularly in community-based conservation local efforts.

- Description: It has long been recognised that small and medium enterprises (SMEs) account for an overwhelming part of businesses worldwide and that they contribute considerably to private sector Gross Domestic Product (GDP), growth and are the source for most new employment opportunities. It may therefore be postulated that scaling and growing SMEs are of notable importance to the economic wealth of the country and to this extent it eliminates economic stagnation. This treatise argues the significant impact that entrepreneurship exerts on the South African economy. This would allow the role players to identify the strategic interventions necessary to grow and scale SMEs. A literature review was conducted to develop insights on the factors that affect the scalability of SMEs. The aforementioned section expounds on the concept of SMEs. Secondly, the emergence of SMEs across developed and emerging economies is discussed by exploring the United States of America, Europe and the BRICS economies respectively. Thirdly, SMEs in the South African context are explored. Fourthly, the requirements and challenges of SMEs in the South African economy are highlighted. The primary data for this study were collected from the sample by means of an online questionnaire and through fieldworkers who were deployed to collect responses from the sample group. A representative sample of n = 295 responses were received. Descriptive statistics were used to summarize the data in a way to simplify the interpretation of the data. Inferential statistics were used to authenticate conclusions made from the data. The model was developed and identified the following factors as exerting influence on the scalability of SMEs: Access to Finance, Access to Markets and Access to Human Capital, Entrepreneurial Intention, Regulatory Framework, Business Support and Networks. The average mean values of the factors were then used to establish their position or ranking as determined from the responses received. All factors ranked above a mean value of 3 which indicates that SMEs have a neutral to positive opinion of the factors identified in the model. According to a one-tailed t-test from the sample of SMEs it was shown that two of the nine factors had a large effect size in the factors of Human Capital and Entrepreneurial Intention. The Scalability of SMEs’ model developed in this study specified the factors that influence the growth of SMEs.

Mannich base metal complexes and their thiocyanate analogues as catalysts in the oxidation of Catechol

- Description: The study focused on the design of new Cu(II) and Fe(III) complexes, with or without thiocyanate (NCS-), as possible candidates of catechol oxidation using 3,5-di-tert-butyl catechol (3,5-DTBC) as substrate. Two classes of Mannich bases were studied depending on the active methylene group from which they were formed, being either p-cresol or acetaminophen. The ligands were characterised by 1H and 13C NMR spectroscopy. Crystal structures of three of the ligands are newly reported, along with detailed discussion of polymorphism observed in one of the ligands, and the nature of the hydrogen within the ligands in the solid state as well as in solution. The Mannich bases behaved as bidentate (NO), tridentate (NNO) and tetradentate (NNOO) ligands on coordination to Cu(II) and Fe(III) ions in which the hydroxyl group may be protonated or deprotonated. Coordination was determined by IR spectroscopy, investigating shifts in vOH, vC-O and in vCNC of the Mannich bases. The vCNC stretching frequencies v1 and v2 of asymmetrical piperazine Mannich bases were observed to shift upward in few cases upon complexation and this is attributed to (chair-boat) conformational change. The mode of coordination of the thiocyanate was determined by IR spectroscopy. Of the forty metal complexes investigated, six groups of metal complexes were identified as follows: (i) Ma(Ln)aClb-cH2O; (ii) Ma(HLn)a(NCS)aClb; (iii) Ma(Ln)a(NCS)aClb; (iv) Ma(HLn)aClb-cH2O; (v) Ma(Ln)a(NCS)a-cH2O; (vi) Ma(HLn)a(NCS)a-cH2O where a = 1 - 2 ; b = 1 - 4, c = 1 - 8. Molar conductivity values of 4.38 - 161.77 Q-1.cm2.mol-1 for the Cu(II) and Fe(III) complexes in DMSO showed that they range from non-electrolytes to 1:1 and 1:2 electrolytes. Electronic spectra for the ligands and the complexes were conducted in DMF and DMSO. The ligands are characterised by and n→n* and n→n* transitions. Intraligand charge transfer transitions peculiar to the nitro group were observed at about 430 nm for the nitro containing ligands. On coordination, these bands overshadowed the d-d transitions particularly for the nitro-Mannich bases. On complexation, ligand to metal charge transfer transitions associated with the hydroxyl were observed between 320 - 420 nm. Charge transfer transitions associated with the thiocyanates were also observed and discussed. The d-d transitions for high spin Fe(III) complexes are spin forbidden and generally uninformative. Those of Cu(II) are spin allowed and allow tentative structural proposals. Square planar and octahedral geometry are generally prevalent in the Cu(II) complexes with trigonal bipyramidal observed in few instances. The Fe(III) complexes are generally octahedral. Thirty-nine of the forty synthesised Cu(II) and Fe(III) complexes were catalytically active on the substrate (3,5-DTBC) in DMF with turnover rates (kcat) reported in the range of 1.86 ± 0.09 to 112.32 ± 3.72 h-1. From this pool of complexes, sixteen isostructural pairs were identified in terms of geometry, molecular formula and the source of the Mannich base and the following conclusions were made: The presence of thiocyanate in the metal complexes reduce catecholase activity; the Cu(II) complexes generally have better activity but the Fe(III) complexes become more relatively active with highly electron donating groups while the Cu(II) complexes become less; dinuclear complexes have greater activity than the mononuclear.

Charge transfer transitions associated with the thiocyanates were also observed and discussed. The d-d transitions for high spin Fe(III) complexes are spin forbidden and generally uninformative. Those of Cu(II) are spin allowed and allow tentative structural proposals. Square planar and octahedral geometry are generally prevalent in the Cu(II) complexes with trigonal bipyramidal observed in few instances. The Fe(III) complexes are generally octahedral. Thirty-nine of the forty synthesised Cu(II) and Fe(III) complexes were catalytically active on the substrate (3,5-DTBC) in DMF with turnover rates (kcat) reported in the range of 1.86 ± 0.09 to 112.32 ± 3.72 h-1. From this pool of complexes, sixteen isostructural pairs were identified in terms of geometry, molecular formula and the source of the Mannich base and the following conclusions were made: The presence of thiocyanate in the metal complexes reduce catecholase activity; the Cu(II) complexes generally have better activity but the Fe(III) complexes become more relatively active with highly electron donating groups while the Cu(II) complexes become less; dinuclear complexes have greater activity than the mononuclear.

- Description: Access to clean and safe water is essential for the survival of human beings. Nevertheless pollution from wastewater treatment plants (WWTPs) effluents often impacts the microbiological qualities of surface waters. Availability of freshwater resources is indispensable for preventing waterborne diseases. The current study evaluated the physicochemical properties and abundance of Vibrio species in selected rivers and WWTPs in the Eastern Cape Province of South Africa, over a one year sampling regime (December, 2016 to November, 2017). Water samples were collected monthly at designated locations along the banks of two rivers, treated effluents from 500 m upstream and downstream discharge points of two WWTPs and examined for physicochemical qualities, prevalence of Vibrio pathogens and their antibiogram profiles using both cultural and molecular techniques. The findings reveal the qualities of Tsomo and Great Fish river qualities with respect to electrical conductivity (EC) (137.75 – 377.69 mg/l), total suspended solids (TSS) (52.00 – 725.19 mg/l) and temperature (12.7 – 23 oC) and the treated effluents of WW-AD and WW-CR WWTPs with respect to EC (525.73 – 1071.89 mg/l), free chlorine (0.00 mg/l – 0.68 mg/l), temperature (12.4 – 28.8 oC), TSS (14.67 – 276.44 mg/l) exceeds the permissible limits set for effluent discharged to freshwater by South Africa guidelines. Other physicochemical qualities such as turbidity (63.11 – 797.17 NTU), BOD (3.30 – 5.26 mg/l) and TDS (68.88 – 148.14 mg/l) for Tsomo and Great Fish river and turbidity (20.33 – 310 NTU), biological oxygen demand (BOD) (1.28 – 4.96 mg/l), and total dissolve solid (TDS) (262.89 – 534.89 mg/l) for WWTPs WW-AD and WW-CR did not comply with WHO and EU standards as no regulation is set for them in the South African guidelines for domestic water usage. Statistical analysis revealed that pH, electrical conductivities, dissolved oxygen and total dissolved solid were significantly different whereas temperature did not differ significantly with respect to the four seasons (P < 0.05). The Vibrio densities for Great Fish river ranged between 0 and 3.29 log10 CFU/ml with the highest obtained in the spring. The Tsomo River Vibrio densities varied between 0 to 3.56 log10 CFU/ml and the maximum densities recorded during summer. The presumptive Vibrio densities in WW-AD and WW-CR WWTPs ranged from 0 to 3.67 log10 CFU/ml and 0 to 4.42 log10 CFU/ml with autumn and spring having the highest loads respectively. Molecular identification of the presumptive Vibrio species revealed 424 positive for the Vibrio genus. Of these, 21.69 percent, 11.79 percent, 8.25 percent and 2.12 percent were confirmed as V. cholerae, V. mimicus, V. parahaemolyticus and V. fluvialis respectively. The presence of potentially Vibrio pathogens in the rivers and treated effluents suggests potential public health threat to the communities relying on receiving watersheds where the effluents are discharged. Results of antibiotic sensitivity testing revealed high sensitivities against Ofloxacin (85.54 percent), Cefuroxime (81.93 percent), and Ciprofloxacin (74.70 percent), whereas resistance against other antibiotics follow this order: Imipenem (42.17 percent), Amoxicillin-Clavulanic Acid (54.17 percent), Ampicillin (63.54 percent), Nitrofurantoin (71.79 percent) and Polymyxin B (97.44 percent). Surprisingly, the resistance of Vibrio species against the known effective Carbapenems was relatively high (Meropenem (38.54 percent) and Imipenem (58.88 percent). Multiple antibiotic resistance phenotypes (MARP) of the isolates were resistant to two or more antibiotics whereas the calculated multiple antibiotic resistance index (MARI) ranged from 0.2 to 0.7. The observed high multiple antibiotics index suggest the recovered Vibrio pathogens are of high antimicrobial usage origin. Increase in antimicrobial resistance profiles towards conventionally used antibiotics as indicated in this study calls for adequate sanitation facilities and proper surveillance programs towards monitoring of antimicrobial resistance determinants in wastewater treatment effluents and receiving watersheds. This will in turn enhance early detection of resistant strains of public health importance, and supports the prompt notification and investigation of outbreaks. It further advocates the need for constant monitoring programme by the relevant regulatory agencies to ensure total compliance of the wastewater treatment facilities to the stipulated standards.

- Description: This study evaluated the coverage of the 2016 #FeeMustFall students’ protests in Eastern Cape Universities by the Daily Dispatch, which is a daily newspaper published in the Eastern Cape Province. The study employed both quantitative and qualitative research methods. Quantitative data were collected and analyzed through content analysis of the Daily Dispatch Newspaper while the qualitative data collected through focus group discussions among selected students of the University of Fort Hare were analyzed using thematic analysis. The study revealed that 31 stories were published by the Daily Dispatch Newspaper during the period of the protest. The tone of the stories suggested that the Daily Dispatch Newspaper was objective in its reportage. Furthermore, framing analysis of the stories showed that conflict news frame was most prominent in the #FeeMustFall students’ protest stories followed by the attribution of responsibility and human-interest frames. Thematic analysis of the focus group discussions revealed that the type of news frame used for the #FeeMustFall student’s protest stories influenced the thoughts and perceptions of readers as the news frames generated similar audience frames. These findings confirm the views highlighted by the agenda setting and framing theories, which underpin this study. This study indicates that news framing plays a significant role in readers’ perception and as well, defines the way information is presented by readers.

- Description: This study investigates the role played by civil society organizations in the consolidation of democracy. It is a comparative study between South Africa and Cameroon. This study utilizes the Habermasian critical theory of civil society which emanates from the liberal ideology of democracy. The objectives of the study were to look at the legislations regulating the operation of NGOs, the activities carried out to consolidate democracy and the challenges faced by these organizations in both South Africa and Cameroon. The qualitative method was used for data collection for the study. Interviews were carried out with NGOs officials and the data was analyzed using thematic analyses. The research found out that there is a liberal legislative framework governing the activities of NGOs in South Africa. On the other hand, though Cameroon laws on association seem liberal, a careful study of these laws revealed a concerted effort from the state to constrain the operation of NGOs. NGOs in South Africa carryout activities such as picketing, publicity stunts, human rights awareness campaigns, anti-corruption campaigns, lobbying of parliament, protests, mass mobilization and public interest litigation to consolidate democracy.In Cameroon, NGOs are involved in activities like strike actions, public protest, human rights and anti-corruption campaign as well as public interest litigation to consolidate democracy. However, South African NGOs face challenges like administrative bottlenecks, legal draws backs, sporadic hostility from the state, inadequate funding and lack of staff capacity. In Cameroon, NGOs faced the following challenges; restrictive legal framework, arbitrary arrests and detention of activists, financial constraints, lack of staff capacity, lack of infrastructure, corruption and internal divisions.

- Description: Since the early reports of MOFs and their interesting properties, research involving these materials has grown wide in scope and applications. Various synthetic approaches have ensued in view of obtaining materials with optimised properties, the extensive scope of application spanning from energy, gas sorption, catalysis biological applications has meant exponentially evolved over the years. The far‐reaching synthetic and PSM approaches and porosity control possibilities have continued to serve as a motivation for research on these materials. With respect to the biological applications, MOFs have shown promise as good candidates in applications involving drug delivery, BioMOFs, sensing, imaging amongst others. Despite being a while away from successful entry into the market, observed results in sensing, drug delivery, and imaging put these materials on the spot light as candidates poised to usher in a revolution in biology. In this regard, this review article focuses current approaches in synthesis, post functionalization and biological applications of these materials with particular attention on drug delivery, imaging, sensing and BioMOFs.

I position the work of these artists practicing in a post-apartheid nation-state alongside the work of contemporary Palestinian artists Larissa Sansour and Khaled Jarrar, who respond to the ongoing struggle of the stateless Palestinian nation divided by colonialism and Israeli apartheid. Each of these artists critiques the construction of the modern nation-state using symbols such as the national flag, the national anthem, the passport and postage stamp, and physical walls and buildings.
