Abstract Context Materials which exceed the balance of their production and destruction lead to the deterioration in the environment. Plastic is one such material which poses a big threat to the environment. A huge amount of plastic is produced and dumped into the environment which does not readily degrade naturally. In this paper, we address the organization of a large body of literature published on the management of waste plastics being the most challenging issue of the modern world. Objectives To address the issue of the management of waste plastics, there is a dire need to organize the literature published in this field. This paper presents a systematic literature review on plastic waste, its fate and biodegradation in the environment. The objective is to make conclusions on possible practical techniques to lessen the effects of plastic waste on the environment. Method A systematic literature review protocol was followed for conducting the present study [Kitchenham B, Brereton OP, Budgen D, Turner M, Bailey J, Linkman S. Systematic literature reviews in software engineering – A systematic literature review. Inf Softw Technol 2009;51(1):7–15.]. A predefined set of book sections, conference proceedings and high-quality journal publications during the years 1999 to September 2017 were used for data collection. Results One hundred and fifty-three primary studies are selected, based on predefined exclusion, inclusion and quality criteria. These studies will help to identify the fate of different waste plastics, their impact and management and the disposal techniques frequently used. The study also identifies a number of significant techniques and measures for the conversion of waste plastic materials into useful products. Conclusion Five fundamental strategies are used for the handling of plastic waste. These strategies include: recycling, depositing in landfill, incineration, microbial degradation and conversion into useful materials. All of these methods have their own limitations, due to which there is need to explore the studies for optimum solutions of the management of plastics waste.

The National Tourism Policy of Malaysia is known as the National Ecotourism Plan 2016-2025. It focuses on progressive and competitive tourism in the country by giving full thrust to appreciating a prosperous environment for stakeholders in the tourism sector. Hence the study of the systematic literature review focuses on several elements as the determinants of tourism policy namely Malaysia Tourism. Consequently, each of the previous study elements will explore the scope and dimensions functionality of each scientific article is consistently discussing to analyse the year in which the authors regularly publish their publications. This is to prove that a significant element of publication by the author. Meanwhile, the scope of the study by the author also risked the priority areas in each article by the authors of each element. It is important to prove that the scope supports the main headline of the paper which deals with the formulation of the National Tourism Policy. In fact, dimensions give priority to what they want to achieve in each article from the authors related to Tourism Policy. This paper reviews the Qualitative Method concept by referring to Content Analysis. As a result, it will illustrate that dimensions will be in sync with Tourism to achieve the national tourism policy aspirations.

This chapter provides a brief description of the methodology used in this book by the following chapters (i.e. “Brand Attachment” [Chapter 3] and “Product Attachment” [Chapter 4]). Applied to address the criticism that literature reviews are naturally liable to subjective choices by the author(s), systematic reviews are based on a methodological protocol intended to minimize subjective biases, while increasing transparency and replicability. After reporting the principles of systematic literature review, the chapter presents how the method has been applied in the research presented throughput the pages of this book.

BackgroundClinically assisted hydration (CAH) can be provided in the last days of life as drinking declines. The impact of this practice on quality of life or survival in the last days of life is unclear. Practice varies worldwide concerning this emotive issue.MethodSystematic literature review and narrative synthesis of studies evaluating the impact of, or attitudes toward, CAH in the last days of life. Databases were searched up to December 2019. Studies were included if the majority of participants were in the last 7 days of life, and were evaluated using Gough’s 'Weight of Evidence' framework. Review protocol registered with PROSPERO, registration number CRD42019125837.ResultsFifteen studies were included in the synthesis. None were judged to be both of high quality and relevance. No evidence was found that the provision of CAH has an impact on symptoms or survival. Patient and family carer attitudes toward assisted hydration were diverse.ConclusionThere is currently insufficient evidence to draw firm conclusions on the impact of CAH in the last days of life. Future research needs to focus on patients specifically in the last days of life, include those with non-malignant diagnoses, and evaluate best ways to communicate effectively about this complex topic with patients and their families.

Purpose – The purpose of this paper is to demonstrate the ability to researchers of using design of experiments (DoE) as a structured and systematic approach to performing systematic literature reviews. The authors demonstrate a simple case study illustrating the application of DoE in executing a systematic literature review on two popular topics in higher education: academic leadership and Lean Six Sigma. Design/methodology/approach – The methodology involves the systematic literature review of linking academic leadership with terms such as Lean, Six Sigma, Total Quality Management, Maturity Model and Continuous Improvement. The main tool used to structure the systematic literature review is a Taguchi Orthogonal Array design, specifically an L16 grid and the method is verified by conducting another review, replacing the term academic leadership with simply leadership. Findings – The approach identified at first no research papers linking the terms; however, when academic leadership was replaced with university, 19 research papers where discovered. The verification exercise, linking just leadership with the other search string generated over 1,000 results – demonstrating that the tool can find large volumes of articles if they exist, the search was completed for a ten year time frame – 2004 to 2014. Research limitations/implications – The case study focussed on a field which is known to have little current research and the verification exercise deliberately targeted a known large body of research. The authors will continue to use the approach and refine the technique over time. Practical implications – This approach would help any researcher despite of their discipline to identify opportunities and gaps in the current literature. Originality/value – The paper shows how DoE can be used in an academic research-based process. No other literature review approach currently exists which uses Taguchi approach to DoE to filter the search criteria.

Abstract Background In 2016, the World Health Organization estimated the global incidence of gonorrhea (GC) to be 86.9 million, and the reported incidence of GC in 2017 was 145.8 cases per 100,000 females and 212.8 cases per 100,000 males in the US. GC therefore represents a significant global healthcare burden; as the infection can be recurrent, overall costs can accumulate. We undertook a systematic literature review (SLR) to examine the economic burden of illness for GC in key countries. Methods Systematic searches were conducted in MEDLINE, EMBASE, and Cochrane databases to identify English-language articles published from January 1, 2009–December 1, 2019 reporting data on the economic burden of uncomplicated urogenital GC (uuGC) in the US, the UK, Germany, Japan and China. The SLR was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (2009). Articles were evaluated for eligibility using population, intervention, comparison, outcome, study design and time period criteria (Table). Dual-independent screening was used at both the abstract and full-text levels; data were captured by a single reviewer with validation by a second reviewer. Table. PICOS-T Study Selection Criteria Results The SLR identified 27 eligible articles (Figure), of which 17 studies (16 US, 1 UK) reported the economic burden of uuGC. The studies primarily reported cost data, with a subset reporting limited resource use. Lifetime costs for uuGC, when elaborated upon, considered the potential for pelvic inflammatory disease among women, and epididymitis in men, as well as lifetime medical costs associated with human immunodeficiency virus. Among the 16 studies reporting costs, the total estimated lifetime cost of uuGC in the US reached as high as $162.1 million. Costs varied vastly based on sex, with one study reporting lifetime estimates up to $163,433 for men but $7,534,692 for women in 2005. Nine studies described costs per patient/infection and found average costs ranging from $26.92–$438.46, though most fell in the range of $79–$354. Figure. PRISMA flow diagram of study inclusion and exclusion Conclusion We identified a large body of evidence detailing the economic burden of GC. The cost burden varied by sex and was higher for females. However, the vast majority of the evidence came from the US, highlighting the need for more global research. Disclosures Amber Martin, BS, Evidera (Employee)GlaxoSmithKline plc.
