Regenerative agriculture: A paradigm shift for food production in South Africa

Agriculture and other land use practices have severely affected the quality of soils and food production systems in South Africa. In addition, these practices significantly contribute to greenhouse gas (GHG) emissions. Soil quality is generally associated with soil organic matter (SOM) along with elemental Carbon (C) and Nitrogen (N). Approximately 58% of South African soils contain <0.5% organic C, 38% contain 0.5–2% organic C, and 4% contain >2% organic C. The extensive aridity and lack of SOM content in South African soils cause them to lack resilience and have a delicate nature compared to soils in temperate regions. In a country where almost 60% of the land is degraded, and 91% is prone to desertification, farming practices require a revised framework for land management. The challenge of producing food on degraded land that is often water-scarce and particularly vulnerable to the effects of climate change is a threat to South Africa's food and nutritional security. Therefore, this review aims to equip farmers with knowledge and principles of innovative and sustainable alternatives such as regenerative agriculture that naturally and progressively improves soil quality/fertility and ecosystem health; and reduces GHG emissions through carbon sequestration. Quantitative studies in South Africa show that during 5–90 years of crop cultivation in the Free State province resulted in a 10–73% reduction in C and N relative to natural grasslands. Similar studies reported a 50% reduction in C after 50 years of cultivation on Hutton soil in Pretoria; and a 50% reduction in C after only 3.5 years of cultivation in the Free State. Considering that the world's food systems are responsible for more than a third of anthropogenic GHG emissions, we are convinced that the shifting trend toward regenerative agriculture is a sustainable climate-smart solution for global food production systems.

Factors Influencing Domestic Human Trafficking in Africa: Protocol for a Scoping Review

Background Human trafficking is a human rights violation in every region of the world. The African continent is not spared. Every year, millions of people experience significant health and social consequences. International organizations and governments combating human trafficking are hindered by a lack of knowledge about what factors influence domestic (within-country) human trafficking. Objective This study aims to conduct a scoping review to collate and synthesize literature on factors influencing domestic trafficking in Africa. Methods We will follow Arksey and O’Malley’s framework to answer the question about reported influences on domestic human trafficking and their relative weight. The search strategy will explore PubMed, CINAHL, Web of Science, and Scopus. A total of 2 independent researchers will select quantitative, qualitative, or mixed methods studies that examine relationships influencing domestic human trafficking. We will document our results by following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. We will extract a list of all reported relationships between identified factors influencing domestic human trafficking in each study. Based on a discourse analysis approach, we will weigh the strengths of the relationships based on how frequently they are reported across the included studies. We will summarize the findings as fuzzy cognitive maps depicting the relationships reported in the literature. The maps represent the influences between concepts (nodes) linked by arrows (edges) going from each cause to its outcomes. These maps are helpful visual summaries of the factors associated with domestic human trafficking, allowing a comparison with maps to be created by stakeholder groups. Results This project received financial support in March 2023. We expect to start the project in March 2024. We recruited 2 research staff members to conduct the scoping review and expect to publish the results in March 2025. Conclusions The review will provide a comprehensive understanding of factors influencing domestic human trafficking in Africa. The overlap of human trafficking with other forms of exploitation, the limited literature on domestic human trafficking, and the likely diversity of factors are challenges for the review. We propose strategies to address these challenges. International Registered Report Identifier (IRRID) PRR1-10.2196/56392

Genes, culture, and scientific racism

Quantitative studies of cultural evolution and gene-culture coevolution (henceforth “CE” and “GCC”) emerged in the 1970s, in the aftermath of the “race and intelligence quotient (IQ)” and “human sociobiology” debates, as a counter to extreme hereditarian positions. These studies incorporated cultural transmission and its interaction with genetics in contributing to patterns of human variation. Neither CE nor GCC results were consistent with racist claims of ubiquitous genetic differences between socially defined races. We summarize how genetic data refute the notion of racial substructure for human populations and address naive interpretations of race across the biological sciences, including those related to ancestry, health, and intelligence, that help to perpetuate racist ideas. A GCC perspective can refute reductionist and determinist claims while providing a more inclusive multidisciplinary framework in which to interpret human variation.

The Relationship Between Loneliness, Social Isolation, and Inflammatory Bowel Disease: A Narrative Review.

There is clear evidence that loneliness and social isolation have profound health consequences. Documenting the associations of loneliness and social isolation with inflammatory bowel disease (IBD) symptoms, disease severity, and treatment outcomes could meaningfully improve health and quality of life in patients with IBD. The purpose of this narrative review was to synthesize the empirical evidence on the associations of loneliness and social isolation with IBD symptoms, disease severity, and treatment outcomes. Articles were identified through systematic database searches. Quantitative studies that enrolled patients with IBD were included if they examined one of the following outcomes: (a) loneliness or social isolation or (b) IBD-related symptoms, disease severity, or treatment outcomes. We identified 1,816 articles after removing duplicates. Of the 18 studies that met the inclusion criteria, 15 were cross-sectional and 3 were longitudinal. Overall, studies found that loneliness was associated with greater disease activity, functional gastrointestinal symptoms, IBD illness stigma, depressive symptoms, daily IBD symptom burden, reduced resilience, and poorer quality of life. Social isolation was associated with higher prevalence of IBD hospitalizations, premature mortality, and depression. Findings suggest that loneliness and social isolation are associated with poorer health and quality of life in patients with IBD. Prospective cohort studies examining the biobehavioral mechanisms accounting for the associations of loneliness and social isolation with IBD-related outcomes are needed to guide the development of psychological interventions for individuals living with IBD.

Thyroid Ultrasonography Screening of a Cohort of Male University Students

Objective: To assess thyroid ultrasonographic (US) findings from a male cohort of asymptomatic Saudi Arabian university students. Materials and Methods: Sixty-three university students were enrolled in a quantitative prospective study from February 2024 to April 2024. They were conveniently selected, excluding females. A MyLab40 US equipment system was used with a 7 MHz transducer. The thyroid was evaluated with US for size, echotexture, and abnormalities. The chi-square test, correlations, and descriptive statistics were applied for the data analysis. Results: The mean age of the participants was 21.5 ± 1.1 years, and the mean body mass index (BMI) was 27.03 ± 6.6. 95.2% of participants had normal findings; positive findings were found in 4.8 % of the participants. Of these, 1.6 % had multiple nodules, and 3.2 % had signs of thyroiditis. The statistical analysis revealed no significant association between right and left thyroid lobe lengths compared to BMI ( p = .7 right and left 0.3). Moreover, there was no association between the thyroid echo pattern and the BMI ( p = .4). Conclusion: This cohort study concluded that the thyroid US findings were very limited. There was no statistical correlation between the thyroid lobe length, thyroid echo pattern, compared to participants’ BMI.

The effects of an educational intervention on women's contraceptive preferences in the immediate postpartum period: A cross-sectional study.

To assess postpartum women's contraceptive preferences and the impact of an educational intervention on these preferences, identifying factors motivating method choices. This cross-sectional quantitative study included women within 48 h after delivery in a public Brazilian hospital. Participants were asked about their contraceptive preferences before and after an educational intervention, which aimed to inform women about the importance of early postpartum contraception, available methods, mechanisms of action, effectiveness, proper use, and side effects. A nursing professional explained contraceptives to postpartum women in individual sessions, demonstrating their use on simulators interactively for about 15 min. Statistical analyses were performed using JAMOVI version 2.3.28 and Microsoft Excel 2016. A total of 402 women (226 adolescents and 176 adults) were included. After the intervention, preference for long-acting reversible contraceptives (LARCs) increased significantly from 157 (39.1%) to 279 (68.7%) (P < 0.001). At the initial assessment, contraceptive preferences were injectable hormonal contraceptives (159 [39.6%]), intrauterine devices (IUDs) (109 [27.1%]), and implants (48 [11.9%]). After the educational intervention, IUDs became the most popular method, at 143 (35.6%), followed by implants (133 [33.1%]) and injectables (81 [20.1%]). Among adolescents, there was a significant increase in implant choice (P < 0.001) and a decrease in injectables and pills (P < 0.001; P = 0.006). Adults showed increased preference for implants (P < 0.001) and IUDs (P < 0.001), with a reduction in injectable hormonal contraceptives (P = 0.005) and tubal ligation (P = 0.006). An educational intervention during postpartum period can influence women's contraceptive choices. Timely education was associated with a significant increase in LARC preference.

The Influence of Transformational and Instructional Leadership Styles of School’s Principals on Teacher’s Performance, Motivation, Job Satisfaction and Student Achievement in Primary and Secondary Schools

This study aims to examine the influence of transformational and instructional leadership styles of school principals on teacher performance, motivation, job satisfaction, and student achievement in primary and secondary schools. A literature review method was employed, synthesizing qualitative and quantitative studies published between 2019 and 2024. The selected studies focus on the relationship between principal leadership styles and key educational outcomes, with data retrieved from sources in both English and Indonesian. The findings highlight that instructional leadership significantly improves teacher performance and job satisfaction by providing structured support and guidance. Transformational leadership fosters motivation, enhances job satisfaction, and promotes student achievement through inspiration and collaboration. The synergy between these leadership styles enhances educational outcomes, with principals effectively balancing both approaches. This review fills a gap by exploring how transformational and instructional leadership styles interact to influence teachers and students, offering a clearer understanding of their complementary roles in various educational contexts. The study provides valuable insights for educators and policymakers by emphasizing the importance of situational leadership and the need for leadership development programs for school principals. Adopting a hybrid approach to leadership can further enhance teacher performance and student achievement.

Utilization of complementary and alternative medicine by patients undergoing maintenance hemodialysis for chronic kidney disease in Taiwan: a descriptive investigation.

Despite the paucity of scientific evidence, complementary and alternative medicine (CAM) is widely used for the prevention and treatment of chronic illness, holistic care, and counteracting the adverse effects of conventional therapies. This study aims to determine the prevalence of CAM use and its associated factors among patients undergoing hemodialysis (HD) in Taiwan. This quantitative study was conducted from August 2022 to July 2024 in the HD unit at Kaohsiung Chang Gung Memorial Hospital in Taiwan. Face-to-face questionnaire-based interviews were held with 154 of 163 eligible patients (response rate, 94.5%) at the bedside during HD. The completed questionnaires were entered into a secure computer database. Data was performed by descriptive analysis, Chi-square, and Fisher tests. More than half of the patients were CAM users (n = 86; 56%), and women was associated with significantly more usage of CAM. Fifty-six CAM users took Chinese herbal medicine (CHM), 52.3% (n = 45) used dietary supplements, and 19.8% (n = 17) used acupuncture. The benefit in the effectiveness of CAM was the main reason for use, the need of CAM to improve the well-being and HD-related complication was high. 32.7% of patients had used CAM based on recommendation from their family and friends. More than one-third (33.7%) of patients did not disclose their use of CAM to their doctors, most of them think it is unnecessary. The use of CAM by patients with maintenance HD was relatively frequent. Of these, most used CHM, of which are shown to the trend into routine HD care is inevitable by high coverage and utilization in Taiwanese national health insurance system. These findings indicate that it is important for health care providers working in dialysis to assess CAM use.

Cultural Heritage Management in the Context of Sustainable Tourism: The Case of Öşkvank Monastery (Uzundere, Erzurum)

This research was carried out at the Öşkvank Monastery, located within the Uzundere district of Erzurum province in the northeast of Turkey. Öşkvank Monastery is a significant cultural heritage and tourism asset for the region with a history dating back to the 10th century. Despite its importance as a tourism attraction, the monastery currently lacks any protection or management strategy that threatens the transfer of the monastery to future generations. This research focuses on the management of cultural heritage through sustainable tourism development, and it was conducted using a mixed methodology, combining quantitative and qualitative studies. As part of the research, a survey was made, and Öşkvank Monastery was evaluated in terms of sustainable tourism principles. The survey results showed that the participants did not appreciate Öşkvank Monastery regarding sustainable tourism principles. A SWOT analysis was performed through a focus group study to identify the internal (strengths, weaknesses) and external (opportunities, threats) conditions of the region in relation to sustainable tourism. Based on the SWOT analysis, a TOWS matrix was developed and strategies for sustainable tourism development were formulated. TOWS strategies were classified by the content analysis method, and an eight-step Cultural Heritage Management Framework (CHMF) was prepared.

Memetics across Generations

The following study focuses on the use of memes on social media, their prevalence in conversation and their usage based on the age of the contributors. The main question it asks is whether the use of memes in computer-mediated discourse is a momentary trend or whether it exhibits signs of continuous language evolution. A quantitative linguistic study is employed to answer this question within the scope of the study. The environment of the study, the social media platform analyzed, is Facebook. The article looks at popular pages on Facebook and user reactions to the posts made by their administrators. It identifies memetic responses among them to observe their prevalence within this digital discourse, then it compares them to the user age data available. Based on the quantitative results, the study shows whether the use of memes rises exponentially the lower the approximate age of the user. The most recent demographic studies of Facebook at the time the study was conducted are employed and compared to the quantitative results to surmise whether the result bears traits of digital language evolution. Within the scope of the study and the selected dataset, it demonstrates the aforementioned traits in younger generations and their prevalence on social media. The article provides an example, and a baseline data analysis, of how meme usage rises with younger generations, as well as insights into usage by older generations and discrepancies in digital language evolution markers.

Can acoustic measurements predict gender perception in the voice?

To determine if there is an association between vocal gender presentation and the gender and context of the listener. Quantitative and transversal study. 47 speakers of Brazilian Portuguese of different genders were recorded. Recordings included sustained vowel emission, connected speech, and the expressive recital of a poem. Subsequently, four scripts were used in Praat to extract 16 acoustic measurements related to prosody. Voices underwent Auditory-Perceptual Assessment (APA) of the gender presentation by 236 people [65 speech and language pathologist (SLP) with experience in the area of the voice (SLP), 101 cisgender people (CG), and 70 transgender and non-binary people (TNB)]. Gender presentation was evaluated by visual analogue scale. Agreement analyses were executed among quantitative variables and multiple linear regression models were generated to predict APA, taking the judge context/gender and speaker gender into consideration. Acoustic analysis revealed that cis and transgender women had higher median fundamental frequency (fo) values than other genders. Cisgender women exhibited greater breathiness, while cisgender men showed more vocal quality deviations. In terms of APA, significant differences were observed among judge groups: SLP judged vowel samples differently from other groups, and TNB judged speech samples differently (both p<0.001). The predictive measures for the APA varied based on the sample type, speaker gender, and judge group. For vowel samples, only SLP judges had predictive measures (fo and ABI Jitter) for cisgender speakers. In number counting samples, predictive measures for cisgender speakers included fomed and HNR for CG judges, and fomed for both SLP and TNB judges. For transgender and non-binary speakers, predictive measures were fomed for CG and SLP judges, and fomed, CPPs, and ABI for TNB judges. In the poem recital task, predictive measures for cisgender speakers were fomed and HNR for both SLP and CG judges, with additional measures of cvint and sr for CG judges, and fomed, HNR, cvint, and fopeakwidth for TNB judges. For transgender and non-binary speakers, the predictive measures included a wider range of acoustic features such as fomed, fosd, sr, fomin, emph, HNR, Shimmer, and fo peakwidth for SLP judges, and fomed, fosd, sr, fomax, emph, HNR, and Shimmer for CG judges, while TNB judges considered fomed, sr, emph, fosd, Shimmer, HNR, Jitter, and fomax. There is an association between the perception of gender presentation in the voice and the gender or context of the listener and the speaker. Transgender and non-binary judges diverged to a higher degree from cisgender and SLP judges. Compared to the evaluation of cisgender speakers, all judge groups used a greater number of acoustic measurements when analyzing the speech of transgender and non-binary individuals in the poem recital samples.

Mapping and quantification of potato virus A RNA genomes within viral particles and polysomes in infected plant cells.

Potato virus A belongs to the genus Potyvirus, a group of single-stranded positive sense RNA viruses infecting crops worldwide. To initiate infection in a host, its genome takes part in different activities, viz., translation, replication, encapsidation during the infection cycle. Extensive research has been carried out to scrutinize the stages of potyviral infection cycle and decipher the strategies it employs to cause disease. Nonetheless, the amount of viral RNA taking part in translation and virion formation, at a given time point, is missing. In this study, we quantified the percentage of viral RNA that exists as virions and those that associates with host polysome, relative to total viral RNA in infected plant tissue. We employed a revised version of immune-capture reverse transcription PCR and polysome profiling to address our queries. We tested three different coating antibody concentrations and further optimized the immuno-capture reverse transcription PCR protocol to address its limitation of binding and retaining viral particles. Our results indicate that most of the viral RNA (69%) exists as encapsidated genomes, while 3% of total viral RNA associates with host polysomes. These findings are crucial for correct interpretation of quantitative translational studies in which correlation must be made between the number of polysome-associated transcripts and the amount of protein synthesized.

In-depth analysis of lupeol: delving into the diverse pharmacological profile

Lupeol, a naturally occurring lupane-type pentacyclic triterpenoid, is widely distributed in various edible vegetables, fruits, and medicinal plants. Notably, it is found in high concentrations in plants like Tamarindus indica, Allanblackia monticola, and Emblica officinalis, among others. Quantitative studies have highlighted its presence in Elm bark, Olive fruit, Aloe leaf, Ginseng oil, Mango pulp, and Japanese Pear bark. This compound is synthesized from squalene through the mevalonate pathway and can also be synthetically produced in the lab, addressing challenges in natural product synthesis. Over the past four decades, extensive research has demonstrated lupeol’s multifaceted pharmacological properties, including anti-inflammatory, antioxidant, anticancer, and antibacterial effects. Despite its significant therapeutic potential, clinical applications of lupeol have been limited by its poor water solubility and bioavailability. Recent advancements have focused on nano-based delivery systems to enhance its bioavailability, and the development of various lupeol derivatives has further amplified its bioactivity. This review provides a comprehensive overview of the latest advancements in understanding the pharmacological benefits of lupeol. It also discusses innovative strategies to improve its bioavailability, thereby enhancing its clinical efficacy. The aim is to consolidate current knowledge and stimulate further research into the therapeutic potential of lupeol and its derivatives.

The Perceived Impact of Leadership Practices of Academic Leaders on Student Success in a Higher Education Institution in South Africa

The research reported on in this paper was motivated by the need to investigate student complaints in the higher education sector in South Africa regarding the poor quality of teaching and learning which has resulted in low student success rates in many institutions in the country. To mitigate poor student success rates, higher educational institutions in South Africa need to consider implementing effective leadership practices of academic leaders to support students in their academic journey. This study identified how academic leaders leadership practices are perceived by students in a higher education institution in South Africa, and to identify which leadership practices are more impactful in supporting student success. According to Hoadley, Christie and Ward (2009) and Hallinger (2011), leadership practices are indeed aligned to academic performance. Grajfoner (2024) suggests that effective academic leadership is a key contributor to attaining academic excellence. However, Bryman (2007: 14) asserts that “one of the key problems in Higher Education is that not enough is known about exactly what makes an effective leader and what, in turn, may make them ineffective”. The theoretical framework upon which the study is based was developed by Mukan, Hawryluk and Stolyarchuk (2015: 42), who suggest that “leadership is a derivative quality of people collaborating, co-operating and supporting each other. It is characterized by openness and is a dynamic, inclusive, collegial process that occurs in a particular context”. In this research, a quantitative study was conducted using a purposeful sample selected from the target population of students at a higher education institution in South Africa. The final sample included 78 undergraduate students from the selected institution. The analysis undertaken in the study revealed that perceived leadership practices of academic leaders do have an impact on student success and that student success is not based on any one element of leadership practice alone; instead there are various perceived dimensions of leadership practices that play a role in promoting student performance. The findings of the study highlighted three key leadership practices that impact on student success, namely engagement, support and communication.

Reference intervals of adjacent disc height in fresh osteoporotic vertebral compression fractures and the association with postoperative adjacent segment complications: a quantitative study in Chinese postmenopausal women.

Preoperative adjacent disc height (DH) was found as an independent risk factor for adjacent segment degeneration (ASD) after percutaneous kyphoplasty (PKP), indicating the preoperative status of the adjacent intervertebral discs may be closely related to adjacent segment complications. To establish the reference intervals (RIs) for adjacent DH of fresh osteoporotic vertebral compression fracture (OVCF) in Chinese postmenopausal women, and investigate the association with adjacent segment complications after PKP. Consecutive inpatients diagnosed with fresh OVCF between November 2015 and August 2023 were reviewed. The enrolled patients were divided into subgroups based on injured vertebral level; then, the cranial and caudal DH were measured. The characteristics of DH among subgroups were identified, and specific RIs were established using the indirect Hoffmann method. The associations between DH and adjacent segment complications were assessed using multivariate analysis. The DH of the cranial disc was significantly lower than the corresponding caudal disc in all vertebral levels, which showed an increasing trend from T11 to L4. The RIs of DH were as follows: T11 (cranial), 2.14-5.14mm; T11 (caudal), 2.64-5.89mm; T12 (cranial), 2.69-5.77mm; T12 (caudal), 3.18-6.57mm; L1 (cranial), 3.05-6.59mm; L1 (caudal), 3.40-8.29mm; L2 (cranial), 3.68-8.36mm; L2 (caudal), 4.57-9.78mm; L3 (cranial), 4.53-8.92mm; L3 (caudal), 5.26-10.07mm; L4 (cranial), 4.70-11.42mm; and L4 (caudal), 5.52-12.12mm. Increased risks of adjacent segment complications after PKP were observed in patients with decreased adjacent DH. The estimated vertebral level and disc level-specific RIs for adjacent DH of fresh OVCF were established in the Chinese postmenopausal women population. A decrease in adjacent DH posed high risks of adjacent segment complications after PKP for treating OVCF.

Interventions employed to address vaccine hesitancy among Black populations outside of African and Caribbean countries: a scoping review.

Black people are disproportionately affected by structural and social determinants of health, resulting in greater risks of exposure to and deaths from COVID-19. Structural and social determinants of health feed vaccine hesitancy and worsen health disparities. This scoping review explored interventions that have been employed to address vaccine hesitancy among Black population outside of African and Caribbean countries. This review provides several strategies for addressing this deep-rooted public health problem. The scoping review followed the five-step framework outlined by Arksey and O'Malley. It complies with reporting guidelines from the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Research studies that examined interventions utilized to promote vaccine confidence within Black populations living outside of African and Caribbean countries were reviewed. A total of 20 articles met the inclusion criteria for this study: 17 were quantitative studies and three were mixed-method studies. This scoping review highlighted six themes: educational advancement, messaging, multi-component approaches, outreach efforts, enhancing healthcare access, and healthcare provider leadership. The review identified effective interventions for addressing vaccine hesitancy among Black populations outside Africa and the Caribbean, emphasizing education, multidimensional approaches, and healthcare provider recommendations. It calls for more qualitative research and interventions in countries like Canada and the UK to enhance vaccine confidence and reduce mistrust.

What Does Employee Silence Mean? the Role of Organizational Climate and Burnout

The avoidance of employees to express and share their ideas and opinions about organizational issues leads to the multidimensional concept of employee silence. From an organizational perspective, it is necessary to take in consideration that individuals tend to remain silent about situations that are less positive in the organization. But silence is not just the absence of voice or communication. Silence prevents individuals from carrying out their work in the most appropriate way, can act as a barrier to organizational change and can influence the employee well-being. Acquiescent silence is the retention of information considered relevant, based on resignation and submission (passive retention) and quiescent silence comes from fear of the negative consequences from sharing information, being used as a form of self-protection. Prosocial silence is related to altruistic motives and opportunistic silence is used to obtain personal advantages. It becomes relevant to determine the factors associated with this silence and what are the implications of employee silence on employee well-being. Thus, the objectives of this study are i) to study the of employee silence motives, ii) to understand whether two of the dimensions of the authentizotic organizational climate (leader´s trust and credibility and opportunities for learning and personal development) are antecedents of employee silence and iii) to study the consequences of employee silence motives on burnout. A quantitative study is conducted, using a questionnaire survey applied to a sample of 222 individuals, working in different portuguese organizations. The confirmatory factor analysis identifies four employee silence motives. The regression analyses highlighted that authentizotic psychological climate dimensions, namely learning and personal development opportunities, were predictors of the three dimensions of employee silence: quiescent silence, aquiescent silence and opportunistic silence. Regarding the impact of employees’ silence on burnout, aquiescent silence stood out as the main predictor of different burnout dimensions: emotional exhaustion, personal accomplishment and depersonalization. Finally, it can be concluded that acquiescent silence seems to stand out as the silence variable most explained by authentizotic organizational climate and the one that most explains the appearance of burnout. The findings can be used by human resources managers.
