TL;DR: The authors developed a free-to-use, Open Source R package and web-based Shiny app to allow users to design PRISMA flow diagrams for their own systematic reviews, allowing users to produce standardised visualisations that transparently document the methods and results of a systematic review process in a variety of formats.
Abstract: Reporting standards, such as PRISMA aim to ensure that the methods and results of systematic reviews are described in sufficient detail to allow full transparency. Flow diagrams in evidence syntheses allow the reader to rapidly understand the core procedures used in a review and examine the attrition of irrelevant records throughout the review process. Recent research suggests that use of flow diagrams in systematic reviews is poor and of low quality and called for standardised templates to facilitate better reporting in flow diagrams. The increasing options for interactivity provided by the Internet gives us an opportunity to support easy-to-use evidence synthesis tools, and here we report on the development of a tool for the production of PRISMA 2020-compliant systematic review flow diagrams.We developed a free-to-use, Open Source R package and web-based Shiny app to allow users to design PRISMA flow diagrams for their own systematic reviews. Our tool allows users to produce standardised visualisations that transparently document the methods and results of a systematic review process in a variety of formats. In addition, we provide the opportunity to produce interactive, web-based flow diagrams (exported as HTML files), that allow readers to click on boxes of the diagram and navigate to further details on methods, results or data files. We provide an interactive example here; https://prisma-flowdiagram.github.io/.We have developed a user-friendly tool for producing PRISMA 2020-compliant flow diagrams for users with coding experience and, importantly, for users without prior experience in coding by making use of Shiny (https://estech.shinyapps.io/prisma_flowdiagram/). This free-to-use tool will make it easier to produce clear and PRISMA 2020-compliant systematic review flow diagrams. Significantly, users can also produce interactive flow diagrams for the first time, allowing readers of their reviews to smoothly and swiftly explore and navigate to further details of the methods and results of a review. We believe this tool will increase use of PRISMA flow diagrams, improve the compliance and quality of flow diagrams, and facilitate strong science communication of the methods and results of systematic reviews by making use of interactivity. We encourage the systematic review community to make use of the tool, and provide feedback to streamline and improve their usability and efficiency.

TL;DR: The Fermi Galactic Extended Source Catalog (FESC) as mentioned in this paper provides a complete search for extended sources located within 7° from the Galactic plane, using 6 yr of FermI-LAT data above 10 GeV, and finds 46 extended sources and provides their morphological and spectral characteristics.
Abstract: The spatial extension of a γ-ray source is an essential ingredient to determine its spectral properties, as well as its potential multiwavelength counterpart. The capability to spatially resolve γ-ray sources is greatly improved by the newly delivered Fermi-Large Area Telescope (LAT) Pass 8 event-level analysis, which provides a greater acceptance and an improved point-spread function, two crucial factors for the detection of extended sources. Here, we present a complete search for extended sources located within 7° from the Galactic plane, using 6 yr of Fermi-LAT data above 10 GeV. We find 46 extended sources and provide their morphological and spectral characteristics. This constitutes the first catalog of hard Fermi-LAT extended sources, named the Fermi Galactic Extended Source Catalog, which allows a thorough study of the properties of the Galactic plane in the sub-TeV domain.

TL;DR: In this paper, the authors explore the challenges presented in retaining South Africa's talent at both macro (country) and micro (organisational) levels and explore the reasons for emigration of South African talent during the period 1994-2006 with 84 respondents.
Abstract: The aim of the study was to explore the challenges presented in retaining South Africa’s talent at both macro (country) and micro (organisational) levels. Using a web-based survey placed on eight New Zealand sites, the reasons for emigration of South African talent during the period 1994–2006 were explored with 84 respondents. Utilising a purposive sampling technique, 20 semi-structured interviews were undertaken with identified ‘top talent’ in two financial services companies. Content analysis of the responses from both samples was employed. Reasons for emigration (macro issues) included uncertainty about the future of the country, job insecurity and fears regarding both corruption and violent crime. Reasons for talent loss amongst identified top talent (micro issues) were found to be linked to leadership, organisational culture and employment equity.
