Purpose: The purpose of this study is to examine the implementation methods practised in Abu Dhabi with those in developed countries with established OSH regulatory bodies. Methodology: Qualitative and quantitative research methods were employed to gather primary research data. Workers from various industries in Abu Dhabi were sampled on purpose and asked to respond to questionnaires and interviews on OSH protocol awareness and implementation, and circumstances of workplace incidence. Results: The findings of this study showed that the enforcement of OSH requirements in UAE positively correlated to a reduction in the rate of work-related injury and improved business performance. The quantitative research data showed that the energy sector had the highest score (15) while the tourism sector had the lowest score (5.3) in occupational health systems and improvements in business efficiency and productivity. Implications: The outcomes of this study shed light on the importance of implementing OSH Guidelines for companies to empower their safety managers to fully enforce OSH requirements in their organisations. In conclusion, effective OSH enforcement requires cooperation between general workers and OSH managers and facilitation from business owners.展开更多

Metamorphic rocks exposed in the eastern UAE have traditionally been interpreted as a metamorphic sole to the Semail ophiolite. However, there has been some debate over the possibility that the exposures contain components of older Arabian continental crust. To help answer this question, presented here are new zircon and futile U-Pb geochronological data from various units of the metamorphic rocks. Zircon was absent in most samples. Those that yielded zircon and futile provide dominant single age populations that are 95-93 Ma, partially overlapping with the known age of oceanic crust formation （96.5-94.5 Ma）, and partially overlapping with cooling ages of the metamorphic rocks （95 90 Ma）. The data are interpreted as dating high-grade metamorphism during subduction burial of the sediments into hot mantle lithosphere, and rapid cooling during their subsequent exhumation. A few discordant zircon ages, interpreted as late Neoproterozoic and younger, represent minor detrital input from the continent. No evidence is found in favour of the existence of older Arabian continental crust within the metamorphic rocks of the UAE.展开更多

Patient demographics,location, mechanism/time of injury, and length of hospital stay were all analyzed.RESULTS Two hundred and ten patients were studied. Their mean age was 29.7 years. Males constituted 92%. Sixty-five point one percent of all cases were from the Indian subcontinent. The workplace was the most common location of injury(67.1%), followed by the home(17.1%)and road(6.2%). Machinery caused 36.2% of all injuries,followed by heavy object(20.5%) and fall(11%). Cases injured at home were young(P < 0.0001) with an associated higher incidence of females(P < 0.0001).CONCLUSION Male workers in Al Ain city are at greater risk of sustaining hand injuries, predominantly from machinery. Safety education, personal protection, and the enforcement of safety standards are essential to the prevention and avoidance of hand injury.展开更多

This is an observational study that was conducted during the period of September 2013 through March 2014. A self-administered questionnaire was designed to be distributed by personal interview to the physicians. The questionnaire population consisted of randomly selected physicians practicing in UAE. The questionnaire was piloted by 10 physicians for face and understandability. Demographic data, frequencies and cross tabulation between different variables were calculated. The Chi-square test was used to determine the significance of association between categorical variables (gender, length of medical practice, and specialty) and the perception of physicians. A total of 285 filled questionnaires were returned representing 285 physicians, with a male dominance (65.3%). The average age of the physician screened was 32.4 (SD = 10.38) years with a minimum one year experience and up to 24 years. General practitioners consumed the widest sector (21.8%) followed by cardiologists (15.8%), then internal medicine (10.1%). In the current study, two thirds of the physicians believed that pharmacists could act as a reliable source of general drug information and play an important role in discovering clinical related problems. It was found that the physicians who had fewer years in practice (less than 10 years) and recently graduated had more acceptances to the clinical role of the pharmacist and believed that there should be a clinical pharmacy services in their hospitals (p-value < 0.05). No other statistically significant differences were found from analyzing the data. In conclusion, results suggest that physicians in UAE appear comfortable with pharmacists providing the broad range of services but appear somewhat less comfortable with pharmacists’ provision of direct patient care.展开更多

This study aims to determine the association between overall satisfaction and various aspects of healthcare services in the United Arab Emirates on a country level. Methods: The data was collected from 5855 respondents on the affordability, quality, accessibility, and responsiveness dimensions of health care. Besides frequency tables and descriptive statistics, statistical methods, such as Principal Component Analysis and Multiple Regression, were used to reduce and model the association between dependent (overall satisfaction) and independent (affordability, quality, accessibility, and responsiveness) variables. Results: The preliminary analysis using frequency tables and descriptive clearly highlighted the uncertainty associated with affordability and responsiveness dimensions of healthcare provision in the country. Analysis of variance and t-test results indicated statistically significant differences between perceptions of the respondents based on the socio-demographic factors and other factors such as the kind of insurance held by respondents, having a designated family physician, recent medical visits in the UAE, and intention to go back to home countries for medical treatment. The findings indicated higher satisfaction levels with quality and accessibility and lower satisfaction levels with affordability and responsiveness. Recommendations are provided to address the latter two factors. Conclusion: The study identifies healthcare service provision issues in the United Arab Emirates and recommends enhancing affordability and responsiveness.展开更多

Proper motivation of volunteers is required for sustaining volunteer performance, while encumbrances to optimal engagement in health systems need to be addressed. This study aimed to investigate the main factors that motivate volunteers to participate in the UAE healthcare system, along with exploring the barriers and challenges being faced. Methods: This study was designed as a quantitative cross-sectional study in United Arab Emirates (UAE). A purposive sample of the Adult citizens and residents using purposive sampling directed at all major health volunteer recruitment agencies in UAE, who have volunteered at least once in the health system over the preceding 12 months. Participants Adult UAE residents were selected by a purposive sampling method from February to April 2017. Data were collected through electronic questionnaires using modified Volunteer Motivation Inventory (VMI). Data were analyzed from 667 adults’ residents who were reported to volunteer at least once in healthcare opportunities. Results: About 53% (n = 290) of the volunteers in this sample were full time employed individuals. Almost 63% (n = 422) were female. Overall, assessed self-reported motivations of volunteer participants were high. The main motivation for volunteering in healthcare opportunities in the UAE was Understanding dimension (Mean = 4.68), followed by self-esteem dimension (Mean = 4.60). Eight elements of volunteer motivation showed no statistically significant differences between male and female respondents. Organization/system barriers dimension was the highest among respondents (Mean = 2.9), followed by individual barriers (Mean = 2.6), interpersonal (Mean = 2.06) and contextual (Mean = 2.04).

The chemical analyses of groundwater samples collected from the study area showed that the groundwater salinity is high which resulted from heavy groundwater pumping. High chloride concentrations in groundwater of Mubazarah and Neima might be attributed to the entrapped saline water within the limestone sequence of Jabal Hafit, or it can be the agricultural activities as it clear from the positive relationship between Cl- and Br-. High sulphate concentrations in groundwater might be related to the presence of gypsum and anhydrite within the limestone sequence of Jabal Hafit. The anionic and cationic compositions of groundwater indicate that the chloride and sodium ions are the dominant and presence of bicarbonate and sulphate may reflect the mixing of such water by the recent freshwater through the existing structural lineaments within the study area. The hydrochemical parameters indicate a relative increase in the concentration of calcium, magnesium and sulphate ions and this could reflect the influence of carbonates and evaporite sediments.展开更多

In UAE, groundwater quantity is reduced and its quality is also deteriorated due to the scanty of rainfall and over pumping for different uses. The deficit of groundwater is met by desalinated water and reused of treated wastewater. Agricultural activities have negative impacts on water resources and this causes reduction of groundwater quality as the agriculture the main land use in the UAE and it accounts for more than 70% of groundwater use. The treated wastewater is an alternative source for agricultural activities. To improve the current water situation, a national water resources strategy has been prepared and imple-mented to assist in achieve this target and maintain the country’s water security. This paper intends to give an overview of water resources in the UAE with emphasis on challenges facing the management of these resources.展开更多
