Determinats and Impacts of Foreign Direct Investment in South Africa

This paper examines the determinants and impacts of foreign direct investment in South Africa for the period 1970-2006. Recognising that FDI can contribute to economic growth and development of most countries, South Africa is constantly working to attract FDI and hence its demand has become highly competitive. South Africa has made considerable efforts over the past decade to improve their investment climate. They have liberalized their investment regulations and have offered incentives to foreign investors. This study therefore aims to determine the main determinants and impacts of FDI in South Africa. The study employs the use of the Eviews 6.0 software to carry out empirical tests of the unit root tests, cointegration analysis test and the granger causality test. All these tests would be used to achieve the set objectives of this study. The empirical results of this study reveal that the determinants of FDI in South Africa are human capital development and infrastructure, while the impacts of FDI in the country are increase in economic growth and export. This result agrees with several other empirical studies that have examined the determinants and impacts of foreign direct investment in other countries

Electrical conductivity during incipient melting in the oceanic low-velocity zone

International audienceThe low-viscosity layer in the upper mantle, the asthenosphere, is a requirement for plate tectonics1. The seismic low velocities and the high electrical conductivities of the asthenosphere are attributed either to subsolidus, water-related defects in olivine minerals2, 3, 4 or to a few volume per cent of partial melt5, 6, 7, 8, but these two interpretations have two shortcomings. First, the amount of water stored in olivine is not expected to be higher than 50 parts per million owing to partitioning with other mantle phases9 (including pargasite amphibole at moderate temperatures10) and partial melting at high temperatures9. Second, elevated melt volume fractions are impeded by the temperatures prevailing in the asthenosphere, which are too low, and by the melt mobility, which is high and can lead to gravitational segregation11, 12. Here we determine the electrical conductivity of carbon-dioxide-rich and water-rich melts, typically produced at the onset of mantle melting. Electrical conductivity increases modestly with moderate amounts of water and carbon dioxide, but it increases drastically once the carbon dioxide content exceeds six weight per cent in the melt. Incipient melts, long-expected to prevail in the asthenosphere10, 13, 14, 15, can therefore produce high electrical conductivities there. Taking into account variable degrees of depletion of the mantle in water and carbon dioxide, and their effect on the petrology of incipient melting, we calculated conductivity profiles across the asthenosphere for various tectonic plate ages. Several electrical discontinuities are predicted and match geophysical observations in a consistent petrological and geochemical framework. In moderately aged plates (more than five million years old), incipient melts probably trigger both the seismic low velocities and the high electrical conductivities in the upper part of the asthenosphere, whereas in young plates4, where seamount volcanism occurs6, a higher degree of melting is expected

The influence of men’s masculine gender-role attitude and behaviour on sexual relationships and reproductive health in Malaysia: A cross-sectional study

Background: This article is an extension of previous research on masculinity and sexual and reproductive health using a newly developed local masculinity scale, KANITA Masculinity Scale, to study men’s masculine gender-role attitude and behavior in Malaysia. Objective: To explore how Malaysian men’s masculine gender-role attitude and behavior influence sexual relationships and reproductive health. Materials and Methods: This cross-sectional study used the localized genderequitable men scale to measure the attitude of Malaysian men toward sexual relationships and reproductive health. A questionnaire survey was administered to a sample of 168 men of ages 20–64 yr, in Malaysia. Data were analyzed using SmartPLS version 3.2.6. Results: The findings of the study showed that men’s traditional behavior and controlling nature are positively associated with the inequality in sexual relationships (p < 0.05, t = 1.838; and p < 0.05, t = 3.750, respectively) and reproductive health (p < 0.05, t = 2.196; and p < 0.05, t = 4.133, respectively). In other words, men who offer stronger endorsement of traditional behavior and control over women report more negative condom attitude and greater priority of men’s desire in sexual relationships. In contrast, there was no significant relationship between men’s response to family and feminine roles in men with sexual relationships and reproductive health. Conclusion: Our findings highlight the importance of considering traditional masculinity ideology when considering the role of men in sexual relationships and reproductive health. Our findings suggest gender transformative policies and programs seeking to inspire men for more gender-equitable relationships with their partners. Key words: Attitudes, Masculinity, Gender-role, Sexual health, Reproductive health, Malaysia

Differentiation of pork from beef, chicken, mutton and chevon according to their primary amino acids content for halal authentication

The detection of pork in various food products has been an important subject of study in many countries. The current study was aimed to differentiate pork from selected meats of beef, mutton, chevon and chicken based on their primary amino acid contents using reverse phase-high performance liquid chromatography (RP-HPLC) with derivatization by o-phthalaldehyde (OPA) and ultraviolet (UV) detection. The results show that the most discriminative amino acids between pork and others werevaline, histidine, serine, alanine and arginine. The findings here lay the ground work for the future research to develop a marker for halal meat authentication based on the amino acids content.Keywords: RP-HPLC, OPA, Amino acids, halal meat, por

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Determinants for Mediterranean diet adherence beyond the boundaries: a cross-sectional study from Sharjah, the United Arab Emirates

BackgroundSubstantial evidence embraced the nutrition competence of the Mediterranean diet (MD) as a healthy model for decreasing the risk of chronic diseases and increasing longevity, with the bonus of ensuring environmental sustainability. Measuring adherence to this diet is marginally investigated in the Arabian Gulf region, an area away from the Mediterranean region. The current study aimed to assess the MD adherence among adults in Sharjah/the United Arab Emirates (UAE), and to identify the most influential predictors for MD adherence among the study participants.MethodsA cross-sectional study design was employed using a self-reported, web-based electronic questionnaire that questioned sociodemographics, lifestyle factors, and familiarity with the MD. The MD adherence was assessed by the Mediterranean Diet Adherence Screener validated questionnaire. The adherence level was classified as low for a total score of [0-5], medium [score 6-7], and high (8-13).ResultsThe study included 1314 participants (age 25-52 years) comprised 822 (62.6%) females and 492 (37.4%) males. There was a moderate adherence score (5.9 ± 1.9) among the study participants. The food constituent expressed the lowest contribution to the MD was fish (9.3%), followed by fruits (12.3%), and legumes (18.3%). The multivariable linear regression analysis showed an overall significant linear trend for the association between the MD adherence score and physical activity, while nutrition information from dietitians and social media were the most two strongly related predictors for the higher adherence (β = 0.747; 95% CI 0.51-0.98, and β 0.60; 95% CI 0.269-0.93; p ConclusionThe findings of the current study showed a moderate adherence, low proportion for high adherence, and a gap in the familiarity with the diet name. Being married, physically active, non-smoker, and getting nutrition information from dietitians and social media were the strongest predictors for higher adherence. It is warranted that public health and nutrition specialists/dietitians to tailor new modern approaches for promoting healthy dietary behaviours consistent with the MD

Attachment to Meat and Willingness Towards Cultured Alternatives Among Consumers: A Cross-Sectional Study in the UAE

Background/Objectives: The escalating global demand for meat, as a sequela of population growth, has led to unsustainable livestock production, resulting in a host of environmental and food security concerns. Various strategies have been explored to mitigate these issues, including the introduction of a novel food product, cultured meat. Cultured meat is not yet commercially available, yet public perceptions are already taking shape. To better understand the factors influencing its adoption by consumers, a cross-sectional, web-based study was conducted to examine consumer attitudes toward conventional meat and cultured meat among adults in the United Arab Emirates (UAE). Methods: The survey was conducted between December 2023 and March 2024 and used a convenience snowball sampling method. The questionnaire focused on current meat consumption patterns, meat attachment, and willingness to consume cultured meat. Sociodemographic data, including age, sex, education, and self-reported weight and height, were also collected. Results: Results showed that the vast majority (86%) of participants consumed all types of meats, while more than half (59.3%) were unfamiliar with the term “cultured meat”. Despite this unfamiliarity, about one-third (35%) were somewhat willing to try cultured meat, though more than two-thirds (69%) were reluctant to replace conventional meat with cultured meat in their diet. Male participants and those with higher BMIs showed a significantly stronger attachment to conventional meat. Willingness to consume cultured meat was notably higher among participants aged less than 30 years, those having less formal education, and those who are Arabic. Conclusions: These findings suggest that while interest in cultured meat exists, significant barriers remain, particularly regarding consumer education and cultural acceptance

Sustainable diets among youth: Validity and reliability of a questionnaire assessing knowledge, attitudes, practices, and willingness to change

Background: In light of the global commitment to promoting sustainable dietary choices and the pivotal role of young adults in the adoption of these choices, it is paramount to understand their perspectives of healthy and sustainable diets. The present study aimed to investigate the validity and reliability of a questionnaire examining the knowledge, attitudes, practices, and willingness to change regarding sustainable diets among young adults in the United Arab Emirates (UAE). Methods: Male and female students attending University of Sharjah, UAE (n = 436), completed an online questionnaire consisting of four sections: knowledge, attitudes, practices, and willingness to change with regard to sustainable diets. Of the participants, 106 completed the questionnaire a second time, 1 month later. Factor analysis (FA) (both exploratory and confirmatory), Cronbach-α, interitem correlations, and intra class correlation (ICC) coefficients were used in the data analysis. Results: Exploratory FA revealed four factors corresponding to the components of the questionnaire. Results of the confirmatory FA indicated a good fit: the χ2 df ratio was < 5 (2.3), root mean squared error of approximation was < 0.08 (0.048) and the comparative fit index was above 0.9 (0.901). Cronbach α and interitem correlations were: knowledge: 0.57 and 0.21; attitude: 0.70 and 0.28; practices: 0.76 and 0.39; willingness to change: 0.69 and 0.27. The ICC coefficients, assessing the reliability of the questionnaire, ranged between 0.48 and 0.92 for the various items. Conclusions: The developed questionnaire is a valid and reliable tool that could be used to identify the gaps and opportunities for the development of evidence-based interventions aiming to enhance the uptake of sustainable diets among young adults. © 2023 British Dietetic Association

An innovative state-of-the-art health storytelling technique for better management of type 2 diabetes

Background: Type 2 diabetes (T2D) is a chronic lifelong disease that requires long-term prevention and management strategies in a community setting. A health story is a novel technique that may be used as an effective tool for better prevention and management of T2D. Objective: The main objective of this study is to develop a story to be used as a social health technique based on contemporary scientific knowledge that may be used at a community level for better communication and management of T2D. Methods: A community–academic partnership was formed with a not-for-profit Nutrition Education, Awareness, and Training (NEAT) organization in Khyber Pakhtunkhwa, Pakistan. We agreed to develop a story that may be used as a health and nutrition education communication tool for better management of patients with T2D. The following phases were followed during the story creation process: (1) the theory phase, (2) the modeling phase, and (3) the evaluation phase. Raters evaluated the story to determine its literary and scientific quality, comprehensiveness, and T2D specificity. Results: The title of the story translated into English is “The Story of Diabetes—The Story of Success.” It is text based and contains 86 pages in the local language, “Pashto,” with an English translation. The story is divided into five chapters and describes the initial diagnosis, fear associated with the disease, issues related to referral to certified practitioners, the importance of a balanced diet, and related lifestyle habits. After story evaluation, the raters suggested its literary and scientific quality, comprehensiveness, and T2D specificity (Pearson correlation scores of \u3e0.8). Conclusion: This unique story was created for T2D and found to be of significant quality in terms of its literary and scientific quality, as well as its comprehensiveness and diabetes specificity. As a result, it may be suggested that it can be used in subsequent studies to improve T2D management among adult patients

Comparison of INTERGROWTH- 21st and Fenton growth standards to assess size at birth and at discharge in preterm infants in the United Arab Emirates

Background: Accurate growth assessment of preterm infants is essential in guiding medical care and suitable nutritional interventions. Currently, different growth references are used across hospitals in the United Arab Emirates (UAE). This study aims to compare the INTERGROWTH-21st standards with Fenton growth references regarding birth size classification and at the time of discharge in a sample of preterm infants in the UAE. Methods: A retrospective single-center evaluation of medical records of infants born < 37 weeks of gestation was conducted using data from 2018 to 2020. Anthropometric measurements (weight, length, and head circumference) were obtained at birth and at the time of discharge, and then converted to percentiles according to the two reference standards. Results: A total of 1537 infants with a median birth gestation of 35.3 weeks, and a median birthweight of 2320 g were included. The rates of SGA, AGA, and LGA at birth were 11.5%, 80.42%, and 9.08% using INTERGROWTH-21st growth charts compared to 9.5%, 83.2%, and 7.3% respectively according to Fenton charts. The findings indicated statistically significant differences between the two growth charts classifying of preterm infants based on weight, length, and head circumference (p < 0.05). For every 5 cases assessed as SGA at discharge according to Fenton charts, only 3 were classified as SGA by INTERGROWTH-21st curves. Conclusions: Differences exist between the two growth charts with only moderate agreement. Thus, there is a need for harmonizing growth assessment standards. Misclassification of these vulnerable infants would affect their in-hospital and post-discharge nutrition and medical care plan
