This study presents a comprehensive analysis of an extreme dust event recorded in the Arabian Peninsula and the United Arab Emirates (UAE) between 31 March and 3 April 2015. Simulations of the dust event with the Weather Research and Forecasting model coupled with the Chemistry module (WRF-Chem) were analyzed and verified using MSG-SEVIRI imagery and aerosol optical depth (AOD) from the recent 1-km Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm for MODIS Terra/Aqua. Data from the National Centers for Atmospheric Prediction/National Center for Atmospheric Research (NCEP/NCAR) and the upper-air radiosonde observations were used to understand the synoptic of the event. In addition, the impact of the event on atmospheric and air quality conditions is investigated. The Air Quality Index (AQI) was calculated prior, during, and after the event to assess the degradation of air quality conditions. Simulated temperature, relative humidity, wind speed, and surface radiation were compared to observations at six monitoring stations in the UAE giving R 2 values of 0.84, 0.63, 0.60, and 0.84, respectively. From 1 to 2 April 2015, both observations and simulations showed an average drop in temperature from 33 to 26°C and radiance reduction from about 950 to 520 Wm −2. The AOD modeled by WRF-Chem showed a good correlation with Aerosol Robotic Network (AERONET) measurements in the UAE with R 2 of 0.83. The AQI over the UAE reached hazardous levels during the peak of the dust event before rapidly decreasing to moderate-good air quality levels. This work is the first attempt to demonstrate the potential of using WRF-Chem to estimate AQI over the UAE along with two satellite products (MODIS-MAIAC and MSG-SEVIRI) for dust detection and tracking.

Purpose The purpose of this paper is to identify factors affecting sustainable organizational performance, to build a framework for the United Arab Emirates (UAE) public health-care sector to facilitate sustainable organizational performance and to prioritize the factors for sustainable organizational performance. Design/method/approach The method used in this research is the quantitative method called the analytical hierarchal process (AHP) to help the decision makers in the public health-care sector to prioritize the factors that are affecting sustainable organizational performance. The method will also help to deal with the complexity of the sustainable organizational performance issue by interviewing nine experts in the field. Findings The findings of this research showed 21 sub-factors for sustainable organizational performance in the public health-care sector in UAE. It emphasizes that patient safety and quality of care are the most important factors for sustainable organizational performance. Research limitations/implications This study can be repeated by targeting other private hospitals in UAE. The novelty of this research means that it is the first study done in sustainable organizational performance in the health-care sector in UAE. Practical implications Health-care management can benefit from this research in many ways: Medical errors have a high impact on the hospital’s reputation and these determine the customer demand. Thus, the hospital’s management should give more attention to minimize the medical errors in order to have a sustainable organizational performance. This can be accomplished through clear protocols and procedures that may affect patients’ lives, the hospital’s reputation and organizational performance. Nevertheless, the policymakers should focus on society engagement; focus on social sustainability should be an integral part of their operational and business strategy. According to Abu Dhabi Health Authority (HAAD), the UAE has a highest rate of chronic diseases, such as diabetes, obesity and cardiovascular disease. Cardiovascular disease itself accounted for 36.7% of all 2013 deaths. The health-care sector should focus more on educating the community by conducting workshops, seminars and awareness campaigns across the UAE. In addition, decision makers in the health-care sector should spend more on continued improvement by focusing on lean activities that focus on waste minimization and linking the service quality to the hospital outcomes and patient satisfaction. The fourth highest overall priority weight for both transformational leadership and for the waiting time sub-criteria should also be considered by top management to focus more on hiring, retaining, and developing their transformational leaders, and to keep an eye on the waiting time and improving customer service. This will result in the sustainable organizational performance. Interestingly, all of the HR processes showed the lowest overall weights at 1%, which is a bit strange. HR should play more of a role in sustainable organizational performance, equal to the other sub-factors. Originality/value Originality of this research stems from a reliable and valid framework that can be subsequently used for measuring the organizational performance of health care organizations.

Purpose The purpose of this paper is to explore the adoption of practices and investigating of commonalities/intensities between the factors for measuring organizational effectiveness (OE) across healthcare supply chains in the United Arab Emirates (UAE). Design/methodology/approach System theory coupled with the Supplier-Input-Process-Output-Customer tool was applied to facilitate the linkage between different nodes of the healthcare chain. An exploratory approach was used to explore and measure the importance of various OE factors across various nodes of the healthcare supply chain. Data were collected using a two-stage questionnaire process addressed at personnel in the UAE’s healthcare sector. Findings The study identified that 62 OE factors in the health are supply chain. Of these, 15 are related to suppliers, 14 to the healthcare process, 12 to employees, 8 to patients and the community, 6 to government directives and 7 to branding. In total, 21 common factors were identified and clustered into groups based on commonalities and intensities. Research limitations/implications The study identifies the most important factors for healthcare organizations to achieve OE for different dimensions of operations or performance. These factors will provide valuable insights for decision makers in the sector; it will provide valuable insights to healthcare professionals and academia to investigate more on these factors. Originality/value While there is an increasing research interest in healthcare supply chains, this is the first study to investigate OE across the entire chain while also evaluating the importance of and commonalities in OE-enabling factors.
