Cultivar Responses

In South Africa, the avocado (Persea americana) is an important fruit, grown primarily for export and contributing ZAR 1.75 billion to the gross domestic product of the country. As an export driven industry, optimising exportable avocado fruit volume is a primary concern. Wind induced abrasion and damage by thrips (Thysanoptera: Thripidae), through their feeding on avocado fruit results in corky tissue development (scarring) and making the fruit unsuitable for export. The study aimed to determine the economic losses caused by these agents as well as assess different cultivar responses to scarring damage. Across cultivars, the 1.49% revenue annually due to Scirtothrips aurantii downgrading (3.86% loss factor), translating to ZAR 34.90 million (US$2.39 million). Packhouse study results showed that both thrips and wind abrasion damage accounted for 30% scarring damage, a loss factor of 13.72% and a combined revenue loss of 5.57%. The cultivar ‘Pinkerton’ showed the greatest susceptibility to scarring damage by both wind and S. aurantii whilst the cultivar ‘Carmen®-Hass’ showed a natural predisposition to higher levels of thrips damage. The presence of macadamia trees near avocado trees predisposes avocado fruit to S. aurantii damage.

Efficiency And Productivity

Background: District hospitals (DHs) constitute a significant proportion of public hospitals and consume a more substantial percentage of the government’s total hospital budget. With the level of resources disbursed to DHs, it is essential to ensure efficient allocation and utilization. Hence, this study set out to assess the technical efficiency and productivity of public DHs in KwaZulu-Natal province, South Africa. Methods: Data envelopment analysis (DEA) and Malmquist total factor productivity (MTFP) were used to assess technical efficiency, identify adjustments required to make inefficient facilities more efficient, and determine overall productivity growth. Input data such as medical personnel and output information such as outpatient visits were retrieved from the databases of the district health information system (DHIS), and personnel salary systems (PERSAL) for three consecutive financial years (2014/15, 2015/16 and 2016/17). A total of 38 district hospitals were included in the study. Results: The proportion of technically efficient facilities according to constant return to scale (CRS) were 12 (31.6%), 16 (42.1%) and 14 (36.8%) in 2014/15, 2015/16 and 2016/17, respectively, while according to the variable return to scale (VRS) technically efficient facilities were 22 (57.9%), 19 (50.0) and 21 (55.2%), respectively, for the three consecutive years. On average, the total productivity of DHs increased by 4.8 percent over the three years, which is attributed majorly to technical growth of 6.9 percent. Conclusion: This study showed that a significant proportion of the district hospitals were technically inefficiency. Also, steps that could enable more efficient use of healthcare resources to yield optimal health service delivery were recommended.

Over the past years, there has been a growing significance in supply chain management (SCM) as a vehicle through which many companies/firms can reach a competitive advantage. Despite the importance of supply chain within today’s economy, little is known about how SCM mechanisms can contribute to firm performance. The main purpose of this study was to evince the influence of trust on supplier development, knowledge creation and supply chain performance (SCP) in KwaZulu-Natal (KZN) Province, South Africa (SA). It was a cross-sectional study that was conducted with different samples and several variables. This is a quantitative study which used a probability and non-probability approach. The study was conducted using both the simple random technique and convenience sampling. Descriptive analysis was performed using the IBM SPSS 25 software package. A sample size of 495 respondents was used in this study. In total, 310 questionnaires were received from all respondents who participated in this study. Results specified that trust does not have any direct impact on SCP. However, based on the beta coefficient values, trust predicts better knowledge creation than supplier development. The empirical results show that an organisation/firm that has a high level of knowledge creation with its suppliers will yield greater performance within its supply chain (SC). As the supply chain performance enabled process was empirically defined, firms are therefore able to design appropriate collaborative strategies for their SC. Thus, the capability to integrate external knowledge from different sectors could be a major factor in firms’ improvement capacity. This study recommends that the South African Government must provide training for firm owners and easy funding access for SMEs in KZN to be able to confront competition from local and foreign competitors. Furthermore, this study suggests that staff development and training for public and private sector institutions as well as individual career management enhancement initiatives must be implemented. Collaboration with suppliers and other supply chain associates is strongly recommended, which should increase the chance to gain strengths, trust, knowledge creation, information sharing and technological proficiencies.

Particulate matter less than or equal to 10 μm in aerodynamic diameter (PM10 µg/m3) is a priority air pollutant and one of the most widely monitored ambient air pollutants in South Africa. This study analyzed PM10 from monitoring 44 sites across four provinces of South Africa (Gauteng, Mpumalanga, Western Cape and KwaZulu-Natal) and aimed to present spatial and temporal variation in the PM10 concentration across the provinces. In addition, potential influencing factors of PM10 variations around the three site categories (Residential, Industrial and Traffic) were explored. The spatial trend in daily PM10 concentration variation shows PM10 concentration can be 5.7 times higher than the revised 2021 World Health Organization annual PM10 air quality guideline of 15 µg/m3 in Gauteng province during the winter season. Temporally, the highest weekly PM10 concentrations of 51.4 µg/m3, 46.8 µg/m3, 29.1 µg/m3 and 25.1 µg/m3 at Gauteng, Mpumalanga, KwaZulu-Natal and Western Cape Province were recorded during the weekdays. The study results suggest a decrease in the change of annual PM10 levels at sites in Gauteng and Mpumalanga Provinces. An increased change in annual PM10 levels was reported at most sites in Western Cape and KwaZulu-Natal.

Life Threatening

Critically ill patients admitted to critical-care units (CCUs) might have life-threatening or potentially life-threatening problems. Adverse events (AEs) occur frequently in CCUs, resulting in compromised quality of patient care. This study explores the experiences of critical-care nurses (CCNs) in relation to how the reported AEs were analysed and handled in CCUs. The study was conducted in the CCUs of five purposively selected hospitals in KwaZulu-Natal, South Africa. A descriptive qualitative design was used to obtain data through in-depth interviews from a purposive sample of five unit managers working in the CCUs to provide a deeper meaning of their experiences. This study was a part of a bigger study using a mixed-methods approach. The recorded qualitative data were analysed using Tesch’s content analysis. The main categories of information that emerged during the data analysis were (i) the existence of an AE reporting system, (ii) the occurrence of AEs, (iii) the promotion of and barriers to AE reporting, and (iv) the handling of AEs. The findings demonstrated that there were major gaps that affected the maximum utilisation of the reporting system. In addition, even though the system existed in other institutions, it was not utilised at all, hence affecting quality patient care. The following are recommended: (1) a non-punitive and non-confrontational system should be promoted, and (2) an organisational culture should be encouraged where support structures are formed within institutions, which consist of a legal framework, patient and family involvement, effective AE feedback, and education and training of staff.

Qualitative Phase

In contemporary South Africa, partnerships between service providers in government, non-governmental organisations, the private sector and community based organisations have been identified as a means to strengthen communities and the sustainability of social services. However, the unequal power relations that exists between and within these organisations often leads to fragmentation, duplication, and lack of coordination of social services. Using Fowler’s (1998) conceptualisation of authentic partnerships, this qualitative phase of a larger study explored the challenges of building authentic partnerships in Bhambayi, a predominantly informal settlement in KwaZulu-Natal, South Africa. Individual interviews and a focus group held with nine service providers revealed that intraorganisational challenges, cross-boundary and inter-organisational relations as well as political influences were obstacles to the development of authentic partnerships. The article suggests that open communication, clarity of roles and mutual trust between service providers is vital.

The majority of the South African rural populace is directly or indirectly engaged in agricultural practices to earn a livelihood. However, impediments such as climate change, water shortages, and inadequacy of institutional support have undermined these once thriving subsistence farming communities. Furthermore, poor leadership in hydrology, coupled with a lack of depth in skills at all government levels to facilitate the understanding of the importance of groundwater, has made it near impossible for subsistence farmers to benefit optimally from groundwater. The 2012 drought experienced in South Africa paralysed several subsistence farming communities in KwaZulu-Natal. To revamp subsistence farming and assist these farmers across South Africa, the Department of Water and Sanitation launched interventions, but despite the enormous resources expended, indicators (e.g. unsustainable farming practices, poor crop yield, pitiable living conditions, and poor standards of living) provide evidence that these interventions have not yielded the desired results. This paper seeks to suggest practicable interventions aimed at reducing the vulnerability of subsistence farmers in KwaZulu-Natal. The study pursued a qualitative approach in that it solicited the views of experts on groundwater and in related fields to gain an in-depth perspective. Some of the core challenges undermining the sustainability and growth of subsistence farming in the study area were found to be the inadequacy of experts on groundwater, water shortages, institutional deficiencies, lack of political will, and lack of coordination among stakeholders. Pragmatic recommendations are made to address these challenges, among other things to encourage a South African-Chinese partnership in the hydrology sector.
