According to studies on global plastic manufacturing and the resulting pollution, plastic wastes have been identified as a serious environmental concern. The impact of plastic garbage on marine species, humans, and the environment is a source of public concern, necessitating the need to save ecosystems and the lives that depend on them. Polyethylene terephthalate (PET) water bottles have a significant carbon footprint and represent tremendous waste. In the United Arab Emirates (UAE), PET water bottles are widely utilized, with yearly consumption reaching 450 water bottles per person. This study aims to review the literature on using PET water bottles in the UAE. A systematic literature search was conducted on journal articles, peer-reviewed journal articles, etc., published in the last 12 months. The main aspects of this systematic literature review include information on how plastic wastes are managed in the UAE and worldwide. In addition, it discusses the public health effects caused by plastic wastes, how the consumers of plastic bottles responded to the environmental policies, and so on. The article selection criteria included studies related to plastic water bottles in the UAE, waste management, environmental consequences, etc. A total of 30 articles were selected by initial screening, and 20 met the selection criteria and were included in the final review. To establish the credibility of this research, we understood that it was necessary to survey the UAE population to see the best approach to deal with PET water bottles.
Purpose
The purpose of this paper is to investigate the service quality of wireless telecommunication services in the UAE.
Design/methodology/approach
This study uses the five dimensions of SERVQUAL instrumentation (reliability, assurance, tangibility, empathy and responsiveness) that are believed to represent service quality to approach a result of service quality level through comparing customers’ expectations to their perceptions. A SERVQUAL survey was constructed and distributed among a total number of 100 Etisalat users from four different age groups.
Findings
The results showed a significant difference between users’ expectations and the current level of quality of services in tangibility dimension of quality. The other variables were ranked in this order, assurance, reliability, responsiveness and empathy in service quality.
Research limitations/implications
The research findings encompass individuals from society only and may not be practical to generalize the findings to business organizations or industries as they have special offers and packages designed for their nature of the study.
Practical implications
This research is intensely valuable for Etisalat telecommunication company as it reflects and rates their service provided to the individuals of the society (citizens and residents) from five different critical dimensions. Consequently, it offers the firm the chance to improve the negative gaps in their services. Thus, higher customer satisfaction and loyalty.
Originality/value
This study demonstrated that a multi-cultural society could influence customers’ expectations and perceptions of service quality. The study results showed opposing expectations and perceptions to the same dimension from people of the same age group. The highest gaps were found to be in the tangibility and assurance dimensions whilst the lowest gap was found in the empathy dimension.
Radiology divisions at hospitals face great difficulties to meet the core of the administrative expectations, including serving patients in timely fashion. This gives rise to the need for full review and evaluation of the system in place. One of the top evaluation criteria of any medical institution is the quality of service provided at the same time satisfying the patient needs. This study includes applying discrete event simulation as a management tool. Data related to the processing time were collected. Other data related to the arrival time were retrieved from records over a period of one year. A model was developed and the outcomes provided the hospital management team with a tool to make an efficient administrative decision resulting in improving the quality of the scanning services. Improvement on the operating system was achieved by reducing the patient waiting period and enhancing the quality of the provided service. The main contribution of this study is gearing towards evaluating the efficiency of applying Arena simulation software to a radiology department within a healthcare system. This process is carried out in conjunction with trade-off analysis in decision-making process of the operations of MRI radiology departments. This study is based on optimizing techniques to facilitate the decision-making process at a higher management level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
