Discrimination against LGBTQ+ people in South Africa has shifted from overt hate crimes to covert microaggressions. Microaggression is a term used in psychology to describe casual discrimination against socially marginalised groups, and they occur in three forms: microassaults, microinsults and microinvalidations. Microassaults include verbal and non-verbal discriminatory behaviours. Microinsults include actions or statements which demean a person's identity, and microinvalidations negate the thoughts, feelings or lived experiences of a certain people. Microaggressions have detrimental impacts on lives of people experiencing them and on their interpersonal relationships. The chapter presents a focus on microaggression theory together with microaggression experiences of South African Indian LGBTQ+ people, who have been under-researched. Reference is made to interview extracts from research studies focusing on South African Indian LGBTQ+ people and from e-zine articles focusing on the experiences of South African Indian LGBTQ+ people.

University students are a unique population with great potential to adopt eating habits that promote positive human and planetary health outcomes. The purpose of this study is to illustrate the current perceptions of sustainable eating behaviours among the students and to examine the determinants of sustainable eating behaviours.

Data were collected from December 2020 to May 2021 through focus group discussions among university students in Ontario, facilitated through synchronous online sessions. There were 21 student participants during the course of five focus group sessions (4–5 participants per session) from various departments within the university. The discussions were transcribed and analyzed for main themes and concepts using open coding; deductive coding based on the framework by Deliens et al. as well as the literature; and inductive coding for emerging themes.

The students had different perceptions about what constituted sustainable eating behaviours, some of which were not based on fact. A variety of individual, environmental (macro, micro and social) and university characteristics were mentioned as factors influencing sustainable food choices, with “food literacy” and “campus food” being the top two factors.

This study presents a novel and holistic overview of how sustainable eating behaviours and sustainable foods are perceived among university students and identifies the perceived determinants of adopting sustainable eating behaviours. This study helps with identifying opportunities to promote sustainable eating behaviours among university students and the design/implementation of informed interventions and policies aimed at improving eating behaviours.

This paper aims to discuss the development of a defect classification system that can be used to detect and classify powder bed surface defects from captured layer images without the need for specialised computational hardware. The idea is to develop this system by making use of more traditional machine learning (ML) models instead of using computationally intensive deep learning (DL) models.

The approach that is used by this study is to use traditional image processing and classification techniques that can be applied to captured layer images to detect and classify defects without the need for DL algorithms.

The study proved that a defect classification algorithm could be developed by making use of traditional ML models with a high degree of accuracy and the images could be processed at higher speeds than typically reported in literature when making use of DL models.

This paper addresses a need that has been identified for a high-speed defect classification algorithm that can detect and classify defects without the need for specialised hardware that is typically used when making use of DL technologies. This is because when developing closed-loop feedback systems for these additive manufacturing machines, it is important to detect and classify defects without inducing additional delays to the control system.

South Africa’s wool industry plays an important role in the agricultural sector. The wool industry provides a valuable source of income for farmers who practice sustainable farming practices. However, wool farmers face numerous challenges, such as wool contamination, dirty wool and producing good-quality wool. Good-quality wool is determined by fibre diameter, clean yield, vegetable matter and staple length. This study aims to address these challenges.

A multiple regression analysis of price (R/kg) of White wool and Merino wool was applied to four variables fibre diameter: vegetable matter, clean yield and staple length. The analysis was based on the data for the 2009–2019 data from Cape Wools auctions.

Fibre diameter, clean yield and staple length, with exception of vegetable matter, made a statistically significant contribution to the determination of wool price after all other independent variables were controlled for (p < 0.05). A one-unit (micron) increase in fibre diameter resulted in a 0.404-unit decrease in wool price (R/kg). A one-unit (mm) increase in staple length resulted in a 0.022-unit increase in wool price (R/kg). There was no statistically significant association between vegetable matter and wool price. A one-unit increase in clean yield was associated with a 0.111-unit increase in wool price (R/kg).

Since wool fleeces consist of the largest portion of wool shorn from sheep, it is important for wool farmers to focus on wool with low fibre diameter, high clean yield percentage, low percentage of vegetable matter content and good length of the wool.

Since wool fleeces consist of the largest portion of wool shorn from sheep, it is important for wool farmers to focus on wool with low fibre diameter, high clean yield percentage, low percentage of vegetable matter content and good length of the wool.

In a developing country such as South Africa, this study is important for the following reason. It is understanding the wool characteristics that have the most significance influence on the determination of wool price for Merino wool and White wool might effectively help the wool farmers to adapt their production systems to improve the wool characteristics that determine wool price.

This study identified a need for a study to be conducted on all wool classes.

The World Health Organization Framework Convention on Tobacco Control (WHO FCTC) is the first treaty negotiated under the auspices of the WHO. This study aims to describe progress toward the framework’s goals, setbacks and strategies to update its articles to optimize outcomes.

A review of relevant literature, including papers in this special issue, forms the basis for identifying steps necessary to amplify the impact of the FCTC.

The WHO suggests that there are 1.3 billion users of tobacco globally. The expected deaths associated with tobacco use could be dramatically reduced by hundreds of millions between now and 2060 through measures that improve cessation and harm reduction support among adults. Additional steps needed to achieve the goals of the FCTC include developing new initiatives to address areas of profound neglect (for example, women); investing in global research and innovation; addressing the needs of vulnerable populations; and establishing a mechanism to fund priority actions required by low- and middle-income countries, including support for alternative livelihoods for smallholder farmers.

In November 2020, the WHO FCTC Parties will host their next Conference of the Parties (COP9) in the Netherlands. This paper aims to contribute to the needed policy decisions related to this meeting. Since acceptance of this article, the WHO FCTC team announced that doe to the COVID-19 pandemic COP9 has been rescheduled till November 2021.

There exists a need to prioritize the goals of tobacco control and offer clear strategies for its execution. This paper fills this niche via a thorough and up-to-date analysis of how to amend and enforce the FCTC.

This paper aims to analyze the propulsive performance of small-amplitude pitching foils at very high frequencies with double objectives: to find out scaling laws for the time-averaged thrust and propulsive efficiency at very high frequencies; and to characterize the Strouhal number above which the effect of turbulence on the mean values cannot be neglected.

The thrust force and propulsive efficiency of a pitching NACA0012 foil at high reduced frequencies (k) and a Reynolds number Re = 16 000 are analyzed using accurate numerical simulations, both assuming laminar flow and using a transition turbulence model. The time-averaged results are validated with available experimental data for k up to about 12 (Strouhal number, St, up to 0.6). This study also compares the present numerical results with the predictions of theoretical models and existing numerical results. For a foil pitching about its quarter chord with amplitude α₀ = 8^o, the reduced frequency is varied here up to k = 30 (St up to 2), much higher than in any previous numerical or experimental work.

For this pitch amplitude, turbulence effects are found negligible for St ≲ 0.8, and affecting less than 10% to the time-averaged thrust coefficient CT¯ for larger St Linear potential theory fails for very large k, even for the small pitch amplitude considered, particularly for the power coefficient, and therefore for the propulsive efficiency. It is found that CT¯ ∼ St² for large St, in agreement with recent models, and the propulsive efficiency decays as 1/k, in disagreement with the linear potential theory.

Pitching foils are increasingly studied as efficient propellers and energy harvesting devices. Their performance at very high reduced frequencies has not been sufficiently analyzed before. The authors provide accurate numerical simulations to discern when turbulence is relevant for the computation of the time-averaged thrust and efficiency and how their scaling with the reduced frequency is affected in relation to the laminar-flow predictions. This is relevant because some small-amplitude theoretical models predict high propulsive efficiency of pitching foils at very high frequencies over certain ranges of the structural parameters, and only very accurate numerical simulations may decide on these predictions.

The purpose of this paper is to explore how sustainability reporting is shaped by the global influences and particular national context where businesses operate.

The paper uses both content analysis of published sustainability information and semi-structured interviews with corporate managers to explore how sustainability reporting is used to address unique social and environmental challenges in a developing country – Sri Lanka. The use of integrative social contracts theory in investigating sustainability reporting offers novel insights into understanding the drivers for sustainability reporting practices in this particular country.

The findings reveal that managers’ perceptions about usefulness of sustainability reporting, local contextual challenges and global norms influence the extent to which companies engage in sustainability reporting and the nature of sustainability information reported. In particular, Sri Lankan company managers strive to undertake sustainability projects that are beneficial not only to their companies but also to the development of the country. However, while company managers in Sri Lanka are keen to undertake sustainability reporting, they face different tensions/expectations between global expectations and local contextual factors when undertaking sustainability projects and reporting. This is also showcased in what is ultimately reported in company annual reports, where some aspects of sustainability, e.g. social, tend to focus more on addressing local concerns whereas other disclosures are on issues that may be relevant across many contexts.

Important insights for government and other regulatory authorities can be drawn from the findings of this study. By capitalising on the strong sense of moral duty felt by company managers, policymakers can involve the business sector more to mitigate the social and environmental issues prevalent in Sri Lanka. The findings can also be used by other developing countries to enable pathways to engage with the corporate sector to contribute to national development agendas through their sustainability initiatives and projects.

While the usual understanding of developing country’s company managers is that they try to follow global trends, in Sri Lanka, this research shows how managers are trying to align their responsibilities at a national level with global principles regarding sustainability reporting. Therefore, this paper highlights how both hypernorms and microsocial rules can interact to define how company managers undertake sustainability reporting in a developing country.

The quality of maternal healthcare training is the most optimal degree of health in the delivery of effective, efficient and quality healthcare in midwifery discipline. Student accoucheurs studying at the Free State School of Nursing are faced with resistance, discrimination, rejection and unacceptability by pregnant women during their clinical placement at the Free State maternal healthcare institutions. This results in poor quality of training of student accoucheurs in maternal healthcare. Considerable studies have been conducted on males in midwifery nursing, but no guidelines have been developed to facilitate student accoucheurs' acceptance and improvement of the quality of training in maternal healthcare, hence the purpose of this study.

A descriptive, explorative qualitative design was used in this study. Qualitative focused group discussions (n = 32) were conducted through purposeful sampling method. Data was analysed thematically.

Three main categories emerged: student accoucheurs' related factors with social interactions and relations as a theme; maternal healthcare users’ related factors with transcultural diversity and socio-economic status as themes; nurse training institutions and maternal healthcare institutions service providers-related factors with gender inequality in the work place as a theme. Ultimately, the guidelines to facilitate acceptance and improvement of quality training of student accoucheurs in maternal healthcare institutions were developed and recommended for implementation.

The paper developed guidelines to facilitate acceptance and improvement of quality training of student accoucheurs in Free State maternal healthcare institutions.

Amidst the scarcity of resources, it is undisputable that an effective public procurement performance measurement system (PMS) is required particularly in county governments, especially for Kenya to realize its ambitions in devolved governance system. County governments cannot be effectively evaluated on their performance if the long-term, strategic impact of public procurement processes and projects is not captured. Arising from this backdrop, this study aims to determine the predictors of strategic procurement performance metrics (SPPM) adoption in public procurement PMS of county governments.

Anchored on institutional theory and public sector scorecard model, a survey research design was adopted where data were collected through census from 115 respondents working in procurement, finance and stores department of Kakamega county government. Data were collected using questionnaire (75.56% response rate) and key informant interviews, and analyzed by using multiple regression model and ordinal logistic regression models.

Multiple regression model and ordinal logistics regression revealed that national government support negatively and significantly, and regulatory framework positively and significantly affects the adoption of SPPM.

There is need for formal mechanism that will enable the national government in partnership with the council of governors to be proactively involved in developing procurement performance measurement capacity of county governments. This study’s findings also provide suggestions for a working regulatory framework required for the adoption of SPPM by county governments.

This work adds value to the prevailing body of knowledge on public procurement PMS in the public sector.

While empirical studies establish the importance of procurement planning in achieving value for money (VfM) in procurement, there is scant evidence demonstrating a link between procurement planning and procurement regulatory compliance, and thus VfM. As a result, this study examined how procurement regulatory compliance can be applied when procurement practitioners in Tanzania seek to maximize VfM through procurement planning.

A cross-sectional research design was adopted from which data were collected once through a structured questionnaire. The structural equation modeling (SEM) and Hayes' PROCESS macro test for mediation analysis were used to analyze the collected data.

Procurement planning has a significant and positive relationship with procurement regulatory compliance (ß = 0.491, p < 0.001). Procurement regulatory compliance has a significant and positive relationship with VfM in procurement (ß = 0.586, p < 0.001). Results also show that procurement planning is a significant positive predictor of VfM (ß = 0.257, p = 0.005). Furthermore, the bootstrapping confidence intervals revealed that procurement regulatory compliance significantly mediates the relationship between procurement planning and VfM in procurement.

Although the study was able to accomplish its overall objective, it is limited in terms of the geographical setting under which the study was conducted. Hence, the generalization of research results should be made with caution as each country has specific public procurement laws and regulations governing the conduct of procurement activities in the public sector.

The study contributes to the growing debate on achieving VfM in procurement activities. The study adds to the literature on public procurement by establishing the mediation effect of procurement regulatory compliance on the quest toward achieving VfM in public procurement.
