- Background: Sexually transmitted infections (STIs) are a major global healthcare burden, disproportionately affecting women. Self-sampling interventions for diagnostic purposes have the potential to improve STI healthcare management and expand STI services. However, there is currently no published evidence of the global use of self-sampling interventions to diagnose STIs in women. The main aim of this scoping review was to map evidence on the use of self-sampling interventions to diagnose STIs in women. Methodology: The methodology of this scoping review was guided by Arksey and O’Malley and Levac. A comprehensive literature search was conducted in PubMed, Scopus, Web of Science, Medline (EBSCO), ProQuest, and Cochrane. For grey literature, a search was conducted in Open Grey, World Health Organization, Google, and conference proceedings and dissertations. All search results were screened and assessed for eligibility. Thereafter data from eligible studies was extracted and analysed. The quality of these studies was appraised using the Mixed Methods Appraisal Tool 2018 version. Results: A total of 770 articles were retrieved from databases and grey literature sources. A total of 44 studies were eligible for data extraction following title, abstract and full-text screening. Of the included studies, 63% presented evidence of research conducted in high-income countries and 37% presented evidence in low- and middle-income countries. Studies presented evidence on the following: feasibility of self-sampling in remote areas; acceptance and ease of use of self-sampling interventions; types of self-sampled specimens; pooled samples for diagnosing STIs; laboratory diagnostic assays for STI using self-sampled specimens; and self-testing of self-sampled specimens. Conclusions: Self-sampling interventions are feasible and easy to use and, therefore, can improve STI management and treatment in women across various age groups and various access levels to good-quality healthcare. Despite this, there is a lack of evidence of self-sampling interventions designed according to user preferences. We recommend studies to collaborate with women to co-develop user-friendly self-sampling interventions to diagnose STIs in women.

- Wastewater remains a global challenge. Various methods have been used in wastewater treatment, including flocculation. The aim of this study was to synthesize iron nanoparticles (FeNPs) using a polymeric bioflocculant and to evaluate its efficacy in the removal of pollutants in wastewater. A comparison between the efficiencies of the bioflocculant and iron nanoparticles was investigated. A scanning electron microscope (SEM) equipped with an energy-dispersive X-ray analyzer (EDX) and Fourier transform-infrared (FT-IR) spectroscopy were used to characterize the material. SEM-EDX analysis revealed the presence of elements such as O and C that were abundant in both samples, while FT-IR studies showed the presence of functional groups such as hydroxyl (–OH) and amine (–NH2). Fe nanoparticles showed the best flocculation activity (FA) at 0.4 mg/mL dosage as opposed to that of the bioflocculant, which displayed the highest flocculation activity at 0.8 mg/mL, and both samples were found to be cation-dependent. When evaluated for heat stability and pH stability, FeNPs were found thermostable with 86% FA at 100 ◦C, while an alkaline pH of 11 favored FA with 93%. The bioflocculant flocculated poorly at high temperature and was found effective mostly at a pH of 7 with over 90% FA. FeNPs effectively removed BOD (biochemical oxygen demand) and COD (chemical oxygen demand) in all two wastewater samples from coal mine water and Mzingazi River water. Cytotoxicity results showed both FeNPs and the bioflocculant as nontoxic at concentrations up to 50 µL.

- Corchorus olitorius, a leafy vegetable with high nutrient content, is normally collected from the wild, in areas that are prone to cadmium (Cd) toxicity. However, studies on how Cd accumulation affects vegetative and reproductive traits of leafy vegetables in South Africa are limited. Therefore, this study tested the effect of Cd accumulation on C. olitorius morphological traits. Plants were grown under various Cd concentrations and studied for variation in vegetative and reproductive traits as well as accumulation in roots and shoots. Plants exposed to 5 mg/kg Cd had longer roots with higher moisture content, heavier fresh and dried stems, as well as dried leaves, which indicated a hormetic effect in C. olitorius after exposure to low Cd concentration in the soil. Again, plants treated with 5–10 mg/kg Cd, accumulated toxic (>10 mg/kg dry weight) Cd within shoots and roots, with minor morphological alterations. Plants could survive, with some morphological defects, Cd toxicity up to 20 mg/kg in soil. Only plants exposed to 5 mg/kg could reproduce. Cd accumulation increased with an increase in the soil, with higher accumulation in shoots. The translocation factor was high (>1) in all Cd concentrations. In conclusion, C. olitorius can accumulate toxic Cd, and yet grow and reproduce either normally or better than the control. The proposed dose of Cd that induces hormesis in C. olitorius is 5 mg/kg in the soil. Therefore, C. olitorius is suitable for phytoremediation of Cd contaminated soils, but unsafe for consumption when it grows in such areas.

- Background: Worldwide, immoral cyberspace users have continued to use the Internet to commit crimes; this has caused unease and has called for quick response to the problem especially within the educational sector. The practical value of this study is in its benefit to other researchers who may be attempting to understand South African or Nigerian cyber technology user‘s behaviour; it may also help relevant educational authorities to get relevant understanding of behaviour in the realm of cyberspace. Objectives: This study examined undergraduate students in relation to cyber technology at the University of Zululand (UNIZULU), South Africa, and the Federal University of Agriculture in Abeokuta (FUNAAB), Nigeria. Method: A survey design, questionnaire as the tool for data collection was adapted and samples for the study were drawn from undergraduate students in two conveniently selected universities in South Africa and Nigeria. Overall, 450 undergraduate students were invited to participate in the survey; 380 respondents completed and returned the questionnaire, resulting in a response rate of 84.4% Results: Most of the respondents from the sampled universities reported that they were aware of what constitutes unethical cyber behaviour. Furthermore, the participants revealed that they hardly received orientation at the universities on cyber behaviour. The challenges that the students faces were reported. Conclusion: This study recommends that universities should sustain orientation and/or training programmes on cyber-ethics and cyber security awareness at the start of each academic year. The results of this study may spark further discussions and research on cyber technology access and use in contemporary society.

- The role of principals is crucial in ensuring the overall success of schools. In most cases, the success or failure of students in the terminal examination is attributed to the principals and teachers. Hence, this study explores the role of principals in secondary schools situated in rural communities via the review method. For this purpose, relevant literature was reviewed. The findings revealed that the role of principals in rural secondary schools in South Africa is as crucial as expected from school principals in other similar contexts. They are majorly saddled with eight (8) responsibilities, which include leading teaching and learning, shaping the direction and development of the school, managing quality and securing accountability, developing and empowering self as well as others, managing the school as an organization, working with and for the community, managing staff members of the school, and managing and promoting co-curricular activities. The findings also revealed that the principals of rural secondary schools in South Africa faced various challenges and found it difficult to discharge their duties as expected. Some of the challenges include lack of resources in schools, quality of teaching staff, and professional development opportunities for rural secondary school principals. The study recommends that rural secondary school principals in South Africa should be well trained through periodic workshops and seminars. Also, considering their location, they should be motivated and encouraged to acquire more knowledge by enrolling for courses that will give them the needed skills and qualifications.

- Little attention has been devoted to the study of the economic implication of land conflict, especially as it relates to agriculture in Nigeria, despite increasing incidence of such conflicts and the crucial role of agriculture in the growth and development of the Nigerian economy. This study used data from the Southwest region of Nigeria to explore the prevalence and pattern of land conflict, analyse its determinants and assess its effect on agricultural production. Data were obtained with the aid of a structured questionnaire, from a survey conducted on a sample of 365 crop farmers who cultivated a total of 462 farm plots. Descriptive statistics, probit and multiple regression analytical techniques were used for data analysis. Reports of conflicts on plots were between 1983 and 2017, with most of the incidences (94.5%) occurring in recent years (2003–2017). Two patterns of land conflicts were identified in the study area: Farmer–Farmer (11%) and Farmer–Pastoralist (89%); the figures reveal that the majority of the conflicts were between farmers and pastoralists. The results further show that plot location, plot distance to farmer’s residence, nature of farming and soil quality had significant positive relationships with land conflict, while plot distance to nearby road had a significant negative relationship with land conflict. There was evidence of significant negative impact of land conflicts on crop production and farmers’ income; a reduction of 49% in crop production and as much as 74% reduction in income of farmers. Serious attention from policy makers and agricultural stakeholders on land-related conflicts would ensure sustainability in agricultural production and development.

- Social workers play a pivotal role in HIV-seropositive patients’ treatment and care within South African public antiretroviral treatment (ART) programs. This article is a reflective log of an HIV-seropositive social worker’s observations and reflections on her positionality during a study on HIV-seropositive patients’ experiences of the public ART program in eThekwini, KwaZulu-Natal, South Africa. The primary investigator (PI) utilized various tools and techniques including reflexive bracketing, participatory action research and a reflexive diary to navigate a sensitive study. This was while being cognizant of the fluidity of her insider/outsider positionality. The disclosure of the PI’s HIV seropositive status culminated in all the participants accepting her despite some social workers’ wariness of a study interrogating patients’ experiences. Such disclosure was aimed at creating a warm, transparent research environment where participants felt comfortable sharing significant and sensitive information on their experiences while interacting with social workers. In conclusion, the PI’s disclosure and transparency on her positionality could facilitate opportunities for other HIV-seropositive social workers to openly engage in trustworthy HIV research studies. This is aimed at facilitating and promoting patient-centered care, destigmatizing the disease, and bridging research gaps.

- Background: The South African public antiretroviral therapy (ART) programme is considered one of the largest and most successful ART programmes worldwide. Hence, a study exploring the patients’ experiences of the public antiretroviral therapy (ART) programme in the second decade of the programme is relevant as no study has been published on patients’ experiences at these sites. Objectives: To explore patients’ experiences of care in the public ART programme at four ARV clinics within the eThekwini District, KwaZulu-Natal. Method: A mixed-methods study design with 12 in-depth patient interviews, non-participatory observation, and a stratified random sample of 400 patients completed questionnaires. Qualitative data were thematically analysed. Quantitative data were analysed using a SPSS 24 package to determine frequencies and differences in patients’ responses (p < 0.05). The socio-ecological model framed the study. Results: All 412 patients reported valuing the provision of free ARVs. Patients’ positive experiences included: routine blood results mostly being available, most staff greeted patients, there were sufficient nurses, patients were satisfied with the time that they spent with doctors, clean clinics, and private and safe counselling areas. The negative experiences included: poor relationships with nurses, negative staff attitudes, disrespectful staff, information was lacking, inadequate counselling at times, varying and inflexible appointments, challenges with data capture and registration systems; varying ARV collection frequencies, routine health tests and processes per site, and the absence of patient committees and representatives. Conclusion: The results reflected positive and negative experiences which varied between the facilities, as processes and systems differed at each site. Innovative patient-centred processes and programmes could be implemented to ensure patients have mostly positive experiences. As part of continuous improvement, patients’ experiences should be regularly explored to ensure that the ART programme meets their needs and expectations.

- Synonymous with Nigeria is a deep political cleavage, which causes major political issues to be violently contested along the lines of intricate ethnic, religious divisions. Although efforts have been made to change these narratives through political reengineering and public policy process, but all have failed to achieve the desired goal of national unity and security. Of what degree is the threats of internal crises to the existentiality of Nigeria? How best can the use of public diplomacy help mitigate the danger of Nigeria’s internal crises? Fundamentally, public diplomacy has the capability to transform a country’s socio-political and economic assets, while reversing the negative attitude of people towards these assets if handled very well. Using relational theory, the conflicts and hostility towards others is explained in relation to socio-economic, political, cultural, and religious intolerance amongst the ethnic groups that make up Nigeria. The findings shows that the inability of Nigeria leaders to put the interests of the diversity of Nigeria first and respect the sensibilities of a fragile nation grasping for survival is the worst political crime, ever committed against the country. Concluding that inclusive collaboration and not unhealthy socio-economic and political competition would bring the ethnic groups in Nigerians closer than ever before.

- The study looked at how the differences in gender and the social setting affect society's perceptions of women’s ability to communicate as leaders. Research shows how culture influences individual thinking, language, communication, and behaviour. The study indicated that gender construct influences individuals’ attitudes, emotions, and behaviours. The same is true for assigned positions in society depending on gender and leadership position. The problem identified cultural aspects of leadership that represent variations in gender norms and communication styles for women in leadership and elements linked to sexual distinction. This article, therefore, focuses on the problems that culture influences gender communication. The research adopted a qualitative approach, a systematic analysis of the literature of the baseline data collected, forming part of a randomised controlled sample collection. The findings indicate the persistent gender discrepancies in communication in several contexts, as women prefer to use more concrete vocabulary in several contexts, emphasising how people can achieve goals, including specifics, and using terms that are easy to imagine. It is no mystery that we are in a period of transformation, and attitudes about sex and gender leadership are changing, therefore, understanding the problems of sexual difference and women’s ability to communicate in leadership can be addressed by creating and strengthening an adequate framework with the condition of a mentality change.
