The contribution of parental factors to adolescents’ deviant behaviour in South Africa: Evidence from three rural communities in South Africa

Challenges associated with adolescents are prevalent in South African societies. During the adolescence stage, children may become involved in deviant behaviour. Although a significant number of studies have focused on the factors that contribute to adolescents’ deviant behaviour, including parental factors, there is paucity of research specifically in rural communities. This study explores the contribution of parental factors to adolescents’ deviant behaviour in rural communities in South Africa. Guided by the qualitative approach, the present study makes use of semi-structured interviews to collect data and thematic analysis to analyse data. The parental factors identified include less parental supervision, a lack of support, an absence of parental discipline, parent’s lack of concern and the inability of parents to be role models

How South African families protected themselves during the COVID-19 pandemic: a qualitative study

The World Health Organization (WHO) reported a cluster of cases of ‘viral pneumonia’— ‘Coronavirus Disease 2019’ (COVID-19)—in Wuhan City, the People’s Republic of China on 31 December 2019. To curb the spread of the virus, various containment measures were introduced. However, no study has explored how families protected themselves during the pandemic. Therefore, this study explored how families protected themselves during the COVID-19 pandemic using a qualitative exploratory design. Thirty-one adult participants, representing families in the Western Cape province of South Africa, were virtually interviewed. The sampling approach was both convenient and snowball. The data were analysed using thematic analysis. The results show that families followed and adapted to the mainstream protection measures as implemented by the South African government but in addition believed that adherence to non-pharmaceutical interventions would protect them from contracting the virus. Therefore, the government and other stakeholders should support families in making it easier to protect themselves during the current and future pandemic(s)

Lessons learnt during covid-19 lockdown: A qualitative study of south african families

In a pandemic, such as COVID-19, with every single person struggling to deal with the unknown, it is often within the family that support is found but it is also within the family that circumstances, contexts and behaviours could further drive the pandemic and where they struggle to cope. This is novel research in the South African context with no known information regarding family life during and post the pandemic. This study, therefore, explores the lessons learnt during COVID-19 by South African families. A qualitative approach was employed to guide the gathering and analysis of the data. Data were collected from a sample of 31 family members above the age of 18 years from communities of the Western Cape Province and analysed through thematic analysis. According to the participants interviewed some of the significant lessons learnt from the lockdown include hygiene and health consciousness, appreciation for family, valuing life, self-introspection, less dependency, remote working, and financial savings. The realisation of such lessons even post-pandemic has the potential of strengthening families to be a resource of coping and resilience during very difficult times at the same time, contributing to greater physical, social, and economic functioning of families across South Africa

Highly efficient chiral metal cluster systems derived from Ru-3(CO)(12) and chiral diiminodiphosphines for the asymmetric transfer hydrogenation of ketones

The chiral Ru cluster-based catalyst systems generated in situ from Ru-3(CO)(12) and chiral diiminodiphosphine tetradentate ligands effected asymmetric transfer hydrogenation of propiophenone in 2-propanol, leading to 1-phenyl-1-propanol in 94% yield and with 96% ee

The Role of Drought Stress on Aflatoxin Contamination in Groundnuts (Arachis hypogea L.) and Aspergillus flavus Population in the Soil

Aflatoxins are naturally occurring toxic chemical substances that are produced by fungal species called Aspergillus flavus. The toxic substances are secondary metabolites, which contaminate groundnut while growing in the field and also post-harvest. Drought stress is one of the factors that contribute to increased aflatoxin levels in groundnut during field production. This study was conducted in a screen house at ICRISAT-Chitedze Agricultural Research Station, Malawi to investigate the effects of drought on aflatoxin contamination and A.flavus population in the soil. Four drought stress levels; prolonged (4 weeks), min (3 weeks), mild (2 weeks) and no drought were imposed on five groundnut varieties at pod filling stage. Soil samples were collected from each plot four times; at planting, beginning of drought, end of drought and at harvest. Aflatoxin levels in groundnut grain samples were estimated by use of neogenstrips read with mobile assay tablet reader. Population densities of A.flavus in soil samples collected from the plots were estimated using serial dilutions plated on the selective media, modified dichloran Rose Bengal (MDRB) and quantify A.flavus within 3 days after incubation at 37°C.The results showed that there were significant differences in aflatoxin contamination between drought stress levels (p = 0.011). High aflatoxin contamination was observed under prolonged drought (22.0 ppb) compared to and no drought treatment (1.5 ppb). None of the varieties used in the study showed either resistance or susceptibility to aflatoxin contamination under drought or adequate soil moisture. The results also showed that there were significant differences in A.flavus population at drought period and harvesting time and the mean population of A.flavus in prolonged drought at end of stress and harvesting were 8511 and 6044 cfu/g of soil respectively. It was concluded that drought contribute to aflatoxin contamination in groundnut, and also increased the A.flavus population in soil and also at harvesting

Synthesis and characterization of ZnO nanostructures using palm olein as biotemplate

Background: A green approach to synthesize nanomaterials using biotemplates has been subjected to intense research due to several advantages. Palm olein as a biotemplate offers the benefits of eco-friendliness, low-cost and scale-up for large scale production. Therefore, the effect of palm olein on morphology and surface properties of ZnO nanostructures were investigated. Results: The results indicate that palm olein as a biotemplate can be used to modify the shape and size of ZnO particles synthesized by hydrothermal method. Different morphology including flake-, flower- and three dimensional star-like structures were obtained. FTIR study indicated the reaction between carboxyl group of palm olein and zinc species had taken place. Specific surface area enhanced while no considerable change were observed in optical properties. Conclusion: Phase-pure ZnO particles were successfully synthesized using palm olein as soft biotemplating agent by hydrothermal method. The physico-chemical properties of the resulting ZnO particles can be tuned using the ratio of palm olein to Zn cation

Study of e+e−→ppˉe^+e^- \rightarrow p\bar{p} in the vicinity of ψ(3770)\psi(3770)

Using 2917 $\rm{pb}^{-1}$ of data accumulated at 3.773~$\rm{GeV}$, 44.5~$\rm{pb}^{-1}$ of data accumulated at 3.65~$\rm{GeV}$ and data accumulated during a $\psi(3770)$ line-shape scan with the BESIII detector, the reaction $e^+e^-\rightarrow p\bar{p}$ is studied considering a possible interference between resonant and continuum amplitudes. The cross section of $e^+e^-\rightarrow\psi(3770)\rightarrow p\bar{p}$, $\sigma(e^+e^-\rightarrow\psi(3770)\rightarrow p\bar{p})$, is found to have two solutions, determined to be ($0.059\pm0.032\pm0.012$) pb with the phase angle $\phi = (255.8\pm37.9\pm4.8)^\circ$ ($<$0.11 pb at the 90% confidence level), or $\sigma(e^+e^-\rightarrow\psi(3770)\rightarrow p\bar{p}) = (2.57\pm0.12\pm0.12$) pb with $\phi = (266.9\pm6.1\pm0.9)^\circ$ both of which agree with a destructive interference. Using the obtained cross section of $\psi(3770)\rightarrow p\bar{p}$, the cross section of $p\bar{p}\rightarrow \psi(3770)$, which is useful information for the future PANDA experiment, is estimated to be either ($9.8\pm5.7$) nb ($<17.2$ nb at 90% C.L.) or $(425.6\pm42.9)$ nb
