Background. Healthcare workers play an important role in educating mothers living with HIV regarding appropriate infant and young child feeding (IYCF) practices. However, it is not known if healthcare workers in eThekwini, KwaZulu-Natal (KZN), have been adequately trained regarding IYCF in the context of HIV and how knowledgeable and confident they are. Objectives. To assess the training, confidence and knowledge of healthcare workers regarding IYCF in the context of HIV. Methods. This was a descriptive cross-sectional study, which used a self-administered questionnaire developed for this survey. Healthcare workers (n=188), primarily doctors and nurses in antiretroviral, antenatal and paediatric departments at three regional hospitals (Addington Hospital, Prince Mshiyeni Memorial Hospital and RK Khan Hospital) in eThekwini, KZN, participated. Results. Only 47.3% (n=89) of the participants had attended formal training on IYCF in the context of HIV. Most participants (n=171; 91.4%) felt they required more training. The mean overall confidence score of the group was 4.54 (standard deviation (SD) 1.28)%. The mean knowledge score of participants regarding IYCF in the context of HIV was 51.7%. The attendance of training did not equate to improved knowledge scores. Conclusions. Although the healthcare workers were confident with counselling on IYCF in the context of HIV, their knowledge levels were lower than expected. This could be attributed to a lack of training or outdated or inefficient training. There is a need to improve the coverage and quality of IYCF and HIV training. Training courses should address behaviour change and test for understanding.

The immunopathogenesis of severe COVID-19 is incompletely understood. In contradistinction to the upper respiratory tract where replicating (culturable) SARS-CoV-2 is recoverable approximately ∼ 4 to 8 days after symptom onset, there is paucity of data about the frequency or duration of replicating virus in the lower respiratory tract (the human lung). We undertook lung tissue sampling (needle biopsy), within ∼2 hours of death, in 42 mechanically ventilated decedents during the Beta and Delta waves. Lung biopsy cores underwent viral culture, histopathological analysis, electron microscopy, transcriptomic profiling, immunohistochemistry and cell-based flow cytometry of deconstructed tissue. 38% (16/42) of patients had culturable virus in the lung (persisting for up to 4 weeks after symptom onset). This, hitherto, undescribed bio-phenotype of lung-specific persisting viral replication was associated with an enhanced pulmonary pro-inflammatory response and variant-specific increased rates of bacterial bronchopneumonia and accelerated death. These findings question existing paradigms and suggest that in a subset of patients, concurrent, rather than sequential active viral replication continues to drive a heightened pro-inflammatory response. Our findings have potential implications for the design of therapeutic interventional strategies and clinical management of severe COVID-19 disease.

Fine liberated valuable particles are often lost to flotation tailings due to inefficient collection by air bubbles, and passivation of their surfaces by oxidation products and slimes when reclaimed from tailings dams. Extensive research covering a diverse range of technologies has been undertaken over the years to find feasible solutions to this problem, with only relatively minor success at an operations scale. A more recent and practical prospect which has already found application in the mining industry is the use of hydrodynamic cavitation devices (HCDs), causing the nucleation of ultrafine (nano) bubbles (NBs) on the surfaces of fine valuable particles, thus aiding their agglomeration and subsequent recovery by micro-bubbles (MBs) and normal sized (macro) flotation bubbles. This paper details investigations that have been undertaken on the Mach HCD reactor, using rougher, cleaner and recleaner feed samples sourced from a UG2 Platinum Group Metal (PGM) tailings operation. The results suggest that the formation of NBs and MMBs, together with enhanced cleaning of particle surfaces, were the dominant mechanisms. This not only lead to activation of valuable mineral surfaces but also depressed the recovery of gangue. The flotation kinetics were analysed using the modified Kelsall model, showing significant improvements in the maximum (fitted) recovery Rmax, together with a reduction in mass pull, for the optimum number of passes of the various feed samples through the reactor. The contributions to the increased recovery due to additional liberation of PGMs from the chromite grains and the increased gas holdup, are being investigated further.

Eastern Boundary Upwelling Systems (EBUS) are well-known for their high productivity and fishery yields. However, being scarcely sampled and poorly represented in global models, their role as CO2 sources and sinks to the atmosphere remains elusive. Here, we present a compilation of shipboard measurements over the past two decades, showing how the Benguela Upwelling System (BUS) in the southeast Atlantic Ocean acts as a CO2 source in the north and CO2 sink in the south. Surface warming of upwelled waters increases the partial pressure of CO2 (pCO2) and outgassing in both regions, but in the south, the biologically-mediated drawdown of CO2 exceeds this warming effect. Here, the biological carbon pump owes its stronger impact on pCO2 to higher shares of upwelling source waters carrying preformed nutrients supplied from the Southern Ocean. Their formation increases pCO2 in surface waters and counteracts human-induced invasion of CO2 in the Southern Ocean. However, their utilization in the BUS compensates for over 20% of the CO2 loss occurring in the Atlantic sector of the Southern Ocean. This emphasizes the role of the BUS as key to improve our understanding of the ocean’s response to climate change and the future evolution of CO2 in the atmosphere.

Porous graphitic carbon nitride (pg-C3N4) was synthesized from bulk g-C3N4 (Bg-C3N4). First, bulk g-C3N4 was prepared by a thermal method with poly-condensation of melamine as a precursor. The pg-C3N4 was synthesized from Bg-C3N4 under ultrasonic treatment in a sulphuric acid medium. Thereafter, pg-C3N4 was combined with commercial silica gel (Slg) to give a fluorescent Slg/pg-C3N4 powder. These prepared materials were characterized by means of distinctive instrumental techniques consisting of UV–visible spectroscopy (UV–visible), fluorescence spectroscopy (FL), Fourier transform infrared spectroscopy (FT-IR) X-ray diffraction (XRD), Raman spectroscopy, Brunauer–Emmett–Teller (BET), scanning electron microscope (SEM), transmission electron microscopy (TEM) and live cell microscopy. The fluorescent Slg/pg-C3N4 powder was used as a labeling agent for the development of latent fingerprints (LFP) on different surfaces such as glass slides, aluminum foil, aluminum sheets, aluminum rods, a compact disc (CD), iron discs, coins, a tea cup and spoon. The LFP images were additionally captured through the use of ultraviolet radiation at 365 nm due to the fluorescent nature of the Slg/pg-C3N4 powder. The LFP images have been also investigated using different commercial powders such as ZnSO4, TiO2 and Iodine vapor for comparison with fluorescent Slg/pg-C3N4 powder. The Slg/pg-C3N4 powder was used to investigate the LFP images submerged in fresh water. Ultimately, the different fluorescent backgrounds of LFP images had been demonstrated using live cell microscopy with pg-C3N4 and Bg-C3N4. The fluorescent Slg/pg-C3N4 powder exhibited potential as a good labeling agent with excessive sensitivity, rapid detection and an eco-friendly nature. This fluorescent Slg/pg-C3N4 powder was also used to develop the LFP images under conditions that are likely to simulate real crime scenes to establish whether this material can be used in real forensic investigations.

This study examines the influence of foreign aid and local ownership in the introduction of inclusive education in Kiribati. The data reported in this paper were collected through interviews with key local stakeholders and these data are part of a larger study. Data were analysed under the major theme of ownership, and were grouped into the four sub-themes of: local responses to inclusive education initiatives; support for inclusive education principles; local attitudes regarding the contribution of Australian Aid; and, sustainability with or without aid support. The results indicate that a positive commitment towards inclusive education is emerging and that Australian Aid provided essential advocacy for children with disabilities in Kiribati through direct management of initiatives by the expatriate administered Kiribati Education Facility. Inclusive education initiatives remain dependent on Australian Aid for direction and sustainability. Sustainability of inclusive education initiatives in Kiribati will depend on continued development of local ownership including community support and commitment by the Government of Kiribati, particularly budgetary support.

Internationally, there is a growing body of research on industry-school partnership, particularly regarding the principles that contribute to effective and efficient partnership models that facilitate vocational-industrial education. However, there are very few articles in the literature that seek to understand the sustainability of industry-school partnerships. Hence, this paper adopted ecological system principles as a framework for understanding the threats that impact on the sustainability of such partnership arrangements. The author reports on a large-scale government led industry-school partnership, the Gateway to Industry Schools Program, established in Queensland, Australia. Central to this initiative is the Queensland Minerals and Energy Academy (QMEA), a lead organisation for 34 schools and 12 multi-national sponsor companies. This research used an explanatory case study methodology sourcing data through interviews and documents. The main findings were that resilience and adaptive capacity are critical principles for the sustainability of ISPs.

Inclusive education in general, and disability-inclusive education in particular, is a high-level priority for development work in aid-supported countries. This paper presents a bottom-up process of developing disability-inclusive education policy in one country – the Solomon Islands. It is well understood that the promotion of quality in disability-inclusive education requires a clearly stated policy; however, in many developing countries, there has been a history of policy borrowing rather than culturally informed policy development. This paper will critically discuss how policy development occurs in aid-funded development work and then offers an alternative model of Australian aid-supported policy development as an in-depth case study.

This article presents a critical analysis of the development and implementation of the 2014 inclusive educational policy in Samoa. While Samoan culture is traditionally founded on inclusive social practices, rather than reflecting these practices in their policy, Samoan policy developers have been under pressure to adopt or borrow policy from other countries. The findings of this intrinsic case study highlight the complexity of formulating inclusive education policies for small developing countries and why policy developers borrow from other developed countries. The theoretical framework used to analyse observation data in this study is based on the notion that national process of development is a powerful influence in educational policy. The authors argue and advocate for the existing but overlooked strengths of the local knowledge community capacity when policy is borrowed from other countries, and how the findings of the case study contribute to future attempts at policy development. We found that the draft policy needs to and does reflect Samoan culture, values and vision. However, adopting foreign practices such as the individual education plan and placement rules is not relevant to the Samoan context. The identification and development of inclusive education beliefs, skills and practices in schools is a priority.

This qualitative study focuses on primary schools’ state of readiness for the introduction of early childhood education. Adopting a multiple case study design, the article explores, through semi-structured interviews and documentation, school heads, teachers-in-charge and classroom teachers’ perceptions of their respective schools’ state of readiness for the installation and implementation of early childhood education. The study established that, while classroom teachers were adequately qualified to implement early childhood education, teachers-in-charge were not. Secondly, school heads received limited induction for the introduction and implementation of early childhood education. Additionally, inadequate teaching-learning resources and lack of on-going teacher support contributed to schools’ lack of readiness for the introduction of early childhood education. The study recommends interventions that curriculum planners and implementers can utilise in order to create conditions that enable primary schools to be ready for introducing and implementing early childhood education. Keywords: early childhood education; implementation; primary school; school readiness

This article explores the concept of human security and examines the scope for its adoption as a normative and policy framework in India. Human security prioritises non-military methods as a means of achieving security without compromising the priorities accorded to traditional security threats. It requires the fulfilment of people’s basic needs and rights. The objective of the article is to show that the human security approach can be usefully applied as a policy measure in India to reinforce successes in the social and economic spheres so that the possibility of dissatisfaction turning into violent opposition and internal conflict is minimised.

As transnational programs are often advocated as a knowledge transfer opportunity between the partner universities, this case study investigated the knowledge transfer (KT) processes between Indonesian and Australian universities through an undergraduate transnational program partnership (TPP). An inter-organisational KT theoretical framework from the business sector was adapted and used to guide the study. The data were generated through semi-structured interviews with key university officers and document analysis from two partner universities. Based on the thematic analysis of the data, the findings demonstrated that the curriculum mapping process facilitated KT. However, different intentions of the partner universities in establishing the program led to declining interest to conduct more KT when expectations were not met. The Indonesian university’s existing knowledge, acquired from other sources through processes that were serendipitous and based on individual lecturers’ personal experience, meant that KT opportunities through the TPP were not always pursued despite written agreement to exchange knowledge with the Australian partner. While KT most evidently resulted in institutional capacity development for the Indonesian university’s school that managed the TPP, dissemination of knowledge to other units within the university was more challenging due to communication problems between the units. Hence, other universities seeking to conduct KT through TPPs need to understand each partner university’s intention in establishing the partnerships, identify the institutions’ needs before seeking knowledge input from the partner university and improve the communication between and within the universities for sustainable benefits.

The elevated levels of primary productivity associated with eastern boundary currents are driven by nutrient- rich waters upwelled from depth, such that these regions are typically characterised by high rates of nitrate-fuelled phytoplankton growth. Production studies from the southern Benguela upwelling system (SBUS) tend to be biased towards the summer upwelling season, yet winter data are required to compute annual budgets and understand seasonal variability. Net primary production (NPP) and nitrate and ammonium uptake were measured concurrently at six stations in the SBUS in early winter. While euphotic zone NPP was highest at the stations nearest to the coast and declined with distance from the shore, a greater proportion was potentially exportable from open-ocean surface waters, as indicated by the higher specific nitrate uptake rates and f-ratios (ratio of nitrate uptake to total nitrogen consumption) at the stations located off the continental shelf. Near the coast, phytoplankton growth was predominantly supported by ammonium despite the high ambient nitrate concentrations. Along with ammonium concentrations as high as 3.6 µmol l–1, this strongly suggests that nitrate uptake in the inshore SBUS, and by extension carbon drawdown, is inhibited by ammonium, at least in winter, although this has also been hypothesised for the summer.

Objectives The aims of this study were to to assess the feasibility of simultaneous testing for the blood-borne viruses (BBV), HIV, hepatitis C (HCV) and hepatitis B (HBV), in the Emergency Department (ED) and ascertain the seroprevalence for these three viruses in this setting. Methods A pilot BBV testing program was undertaken as part of routine clinical care in the ED. All ED attendees aged between 16 and 65 years old who were able to consent were tested over a 55 week period on an opt out basis. Patients with positive test results were linked to clinical services. Interventions aimed at improving testing rates were implemented and evaluated by quality improvement (QI) methodology. Results Of 25,520 age-eligible ED attendees, 6108 (24%) underwent BBV testing; an additional 1160 (4.5%) underwent a standalone HIV test (total of 7268 (28%) individuals).There were 83/7268 (1.1%) non-negative (ie reactive or equivocal) results for HIV and 103/6108 (1.7%) and 32/6108 (0.52%) for anti-HCV IgG and HBsAg, respectively. Of these, 12 (0.17%), 16 (0.26%) and 8 (0.13%) were new reactive tests for HIV, HCV and HBV, respectively, which were able to be confirmed on a second test. Specific QI interventions led to temporary increases in testing rates. Conclusions An opt out BBV testing program in the ED is feasible and effective at finding new cases. However, the testing rate was low at 24%. Although QI interventions led to some improvement in testing rates, further studies are required to identify ways to achieve sustained increases in testing in this setting.

The safety, pharmacokinetics, and antiretroviral activity of lamivudine alone and in combination with zidovudine was studied in pregnant women infected with human immunodeficiency virus type 1 (HIV-1) and their neonates. Women received the drugs orally from week 38 of pregnancy to 1 week after delivery. Neonate therapy began 12 h after delivery and continued for 1 week. Both treatment regimens were well-tolerated in women and newborns. Lamivudine and zidovudine pharmacokinetics in pregnant women were similar to those in nonpregnant adults. Lamivudine and zidovudine freely crossed the placenta and were secreted in breast milk. Neonatal lamivudine clearance was about half that in pediatric patients; zidovudine clearance was consistent with previous reports. HIV-1 RNA could be quantified in 17 of the 20 women. At the onset of labor/delivery, mean virus load had decreased by approximately 1.5 log10 copies/mL in both treatment cohorts. Although not definitive for HIV-1 infection status, all neonates had HIV-1 RNA levels below the limit of quantification at birth and at ages 1 and 2 weeks.

Industry–school partnerships (ISPs) are increasingly being recognised as a new way of providing vocational education opportunities particularly in industries where there are skills shortages. However, there is limited research investigating their impact on school to work transitions. This paper reports on a government-led ISP, the Gateway to Industry Schools Program, established in Queensland, Australia. Central to this initiative is the Resources Academy, a lead organisation for 28 schools and 17 multinational sponsor companies. This research adopted a qualitative case study methodology and draws upon boundary crossing theory as means to understand a Minerals and Energy ISP. We distinguish four types of boundary crossing mechanisms, which partners navigate in ISPs. The main findings were that boundary crossing mechanisms assist ISPs to develop industry-based contextualised curriculum and to prepare school students for employment.
