The main objective of this study is to investigate the impact of a proposed mathematical enrichment program based on the Programme for International Student Assessment (PISA) framework for mathematical literacy. Mathematical literacy is essential because it helps students understand and use real-world mathematics frequently tested in many international assessments. PISA has received special attention because of its place on the national agenda of the United Arab Emirates (UAE), which aspires to become a globally preeminent nation. This quantitative research employed a non-equivalent pre- and post-test quasi-experimental method. A mathematical literacy test was used to collect data from a sample of 102 students of 10th grade in the UAE. The findings revealed a statistically significant difference between the experimental and control groups and an effect size above the mean according to the covariate analysis. The female students recorded greater improvement than the males. Overall, the results obtained from this study revealed that implementing mathematics enrichment programs based on the PISA framework might be one of the solutions to enhance students’ mathematical literacy.

At the peak of the COVID-19 pandemic, the estimated daily use of face masks was at its highest, thereby creating huge public health and environmental challenges associated with the indiscriminate disposal of used ones. The present study assessed Abu Dhabi University students’ handling and disposal of single-use face masks during the pandemic. A cross-sectional study using an online survey questionnaire was used to gather data from 255 students from the target group. Face mask type was found to be significantly influenced by both the student’s gender and age, while the participant’s habit of hand washing after handling a used face mask was found to be significantly influenced by the student’s age. The student’s educational level significantly influenced group decisions regarding the most appropriate face mask to use, as well as environmental and health consequences awareness of indiscriminate face mask disposal. While the students are adequately aware of COVID-19’s impact and had good knowledge of face mask use, a high proportion professed to the unsafe disposal of used face masks in public areas, thereby adding to microplastic pollution in the environment and its associated impacts. The study alluded to the need for strengthening the participant’s knowledge, attitude, and practices as precautionary measures that mitigate the environmental effect of the indiscriminate disposal of used face masks. The findings also call for a collaborative partnership among stakeholders toward designing effective educational campaigns to minimize the environmental impacts posed by face mask disposal.

The purpose of this research was to study the effectiveness and usefulness of a Mathematics Enrichment Program (MEP) from students’ perspectives. The case study presented in this paper highlights the need for the MEP as a possible way to fulfill the needs of high-achieving and gifted students in mathematics in regular classrooms. This MEP was designed to improve students’ mathematical literacy in relation to their readiness for work after school and using mathematics in real life. The process for developing the MEP was described. The sample consisted of 51 grade 10 students from the advanced stream in two high schools in the UAE. Quantitative and qualitative data were collected through a survey designed specifically for this study to gain insight into students’ perceptions of their participation in the MEP experience. Students’ responses to the survey showed a significant impact of the enrichment program on them in many aspects. It is evident that this program helped the students see the importance of mathematics in their life. Although participants reported excitement and more understanding of their mathematics classroom, a few students complained about the of lack of time and difficulty with language and problem-solving skills.

A growing world population is causing hazardous compounds to form at an increasingly rapid rate, calling for ecological action. Wastewater management and treatment is an expensive process that requires appropriate integration technology to make it more feasible and cost-effective. Algae are of great interest as potential feedstocks for various applications, including environmental sustainability, biofuel production, and the manufacture of high-value bioproducts. Bioremediation with microalgae is a potential approach to reduce wastewater pollution. The need for effective nutrient recovery, greenhouse gas reduction, wastewater treatment, and biomass reuse has led to a wide interest in the use of microalgae for wastewater treatment. Furthermore, algae biomass can be used to produce bioenergy and high-value bioproducts. The use of microalgae as medicine (production of bioactive and medicinal compounds), biofuels, biofertilizers, and food additives has been explored by researchers around the world. Technological and economic barriers currently prevent the commercial use of algae, and optimal downstream processes are needed to reduce production costs. Therefore, the simultaneous use of microalgae for wastewater treatment and biofuel production could be an economical approach to address these issues. This article provides an overview of algae and their application in bioremediation, bioenergy production, and bioactive compound production. It also highlights the current problems and opportunities in the algae-based sector, which has recently become quite promising.

This study highlights the appropriateness of innovation management principles to successfully manage radical change in the e-commerce industry during the COVID-19 period. The study focuses on transforming delivery platforms in the context of popular e-commerce organizations in the U.A.E. We conducted the study through interviews, and the results reflect the development of three major themes (shifting consumer behavior, implementation of innovation, and innovation for effective change management) since the beginning of the COVID-19 pandemic. During the transition stage, critical aspects concerning product delivery have emerged to stabilize logistics performance with sustainability. The study suggests that firms need to be faster and more flexible to address the market uncertainty through innovative practices. Similar organizations can use this study to develop mechanisms to improve their delivery systems. Additionally, the study also argues that collaborative innovation significantly contributes to the enhancement of consumers’ well-being and boosts economic growth.

Previous research from our laboratory has shown that exposure to chronic psychosocial stress increased voluntary ethanol consumption and preference as well as acquisition of ethanol-induced conditioned place preference (CPP) in mice. This study was done to determine whether an enriched environment could have "curative" effects on chronic psychosocial stress-induced ethanol intake and CPP. For this purpose, experimental mice "intruders" were exposed to the chronic subordinate colony (CSC) housing for 19 consecutive days in the presence of an aggressive "resident" mouse. At the end of that period, mice were tested for their anxiety-like behavior using the elevated plus maze (EPM) test then housed in a standard or enriched environment (SE or EE respectively). Anxiety and ethanol-related behaviors were investigated using the open field (OF) test, a standard two-bottle choice drinking paradigm, and the CPP procedure. As expected, CSC exposure increased anxiety-like behavior and reduced weight gain as compared to single housed colony (SHC) controls. In addition, CSC exposure increased voluntary ethanol intake and ethanol-CPP. Interestingly, we found that EE significantly and consistently reduced anxiety and ethanol consumption and preference. However, neither tastants' (saccharin and quinine) intake nor blood ethanol metabolism were affected by EE. Finally, and most importantly, EE reduced the acquisition of CPP induced by 1.5g/kg ethanol. Taken together, these results support the hypothesis that EE can reduce voluntary ethanol intake and ethanol-induced conditioned reward and seems to be one of the strategies to reduce the behavioral deficits and the risk of anxiety-induced alcohol abuse.

Recently, the development of building a smart city has been inclined rapidly with the help of emerging technologies in 5G and internet of things (IoT). In addition with smart city, concepts of smart traffic systems and smart health are also being developed. Combining the above two, smart navigation system for ambulances is being coined. When critical patients are referred by an ambulance, there is a lot of time wastage in facilitation of information and the hospital is completely unaware of the patient’s parameters who is arriving beforehand. Therefore, patient monitor and ambulance tracking system is an efficient system used to carry out a quick thirty-second diagnosis using heartbeat, temperature, breath rate sensors to record vital patient parameters required initially by the doctors to start any treatment and remotely transmit these parameters over wireless medium to the hospital even before the ambulance is deployed. The patient also gets an instant way to request an ambulance on touch of a button without having to call up the hospital and also instantly send a short message service (SMS) to an emergency contact giving both the hospital and contact necessary emergency details a lot earlier. This saves a lot of time, each second of which is important to the patient at life risk. The patient can keep a track of the ambulance’s location, which gives them an idea of its arrival and can also get instant navigation toward the nearest hospital for themselves if need be. The device can be kept with the patient and also installed inside the ambulance. The device enables the use of IoT sensors and android applications for better user interaction and efficient information transmission. The model dictated here is potentially outperformed with easiness and in a better way toward smart healthcare monitoring services.

With the beginning of the pandemic of COVID-19 throughout the world, the demand and consumption of hand sanitizers has increased, which had led to a sharp crunch in these products at all levels. This shortage has led to an increase in the prevalence of falsified alcohol-based hand sanitizers, including the illegal addition of methanol to hand sanitizers and the production of hand sanitizers with an alcohol concentration of less than 60%. These findings indicate that regulatory and public health bodies should take an active role in ensuring the safety and quality of antimicrobial products such as alcohol-based hand sanitizers at every stage of the products' lifecycle, including distribution, manufacture and import.

BackgroundThis study estimates the potential health gains achievable in the United Arab Emirates (UAE) with improved controls on environmental pollution. The UAE is an emerging economy in which population health risks have shifted rapidly from infectious diseases to chronic conditions observed in developed nations. The UAE government commissioned this work as part of an environmental health strategic planning project intended to address this shift in the nature of the country’s disease burden.Methods and FindingsWe assessed the burden of disease attributable to six environmental exposure routes outdoor air, indoor air, drinking water, coastal water, occupational environments, and climate change. For every exposure route, we integrated UAE environmental monitoring and public health data in a spatially resolved Monte Carlo simulation model to estimate the annual disease burden attributable to selected pollutants. The assessment included the entire UAE population (4.5 million for the year of analysis). The study found that outdoor air pollution was the leading contributor to mortality, with 651 attributable deaths (95% confidence interval [CI] 143–1,440), or 7.3% of all deaths. Indoor air pollution and occupational exposures were the second and third leading contributors to mortality, with 153 (95% CI 85–216) and 46 attributable deaths (95% CI 26–72), respectively. The leading contributor to health-care facility visits was drinking water pollution, to which 46,600 (95% CI 15,300–61,400) health-care facility visits were attributed (about 15% of the visits for all the diseases considered in this study). Major study limitations included (1) a lack of information needed to translate health-care facility visits to quality-adjusted-life-year estimates and (2) insufficient spatial coverage of environmental data.ConclusionsBased on international comparisons, the UAE’s environmental disease burden is low for all factors except outdoor air pollution. From a public health perspective, reducing pollutant emissions to outdoor air should be a high priority for the UAE’s environmental agencies.
