Aim/Purpose: This paper presents a study of Virtual Communities of Practice (VCoP) evaluation methods that aims to identify their current status and impact on knowledge sharing. The purposes of the study are as follows: (i) to identify trends and research gaps in VCoP evaluation methods; and, (ii) to assist researchers to position new research activities in this domain. Background: VCoP have become a popular knowledge sharing mechanism for both individuals and organizations. Their evaluation process is complex; however, it is recognized as an essential means to provide evidences of community effectiveness. Moreover, VCoP have introduced additional features to face to face Communities of Practice (CoP) that need to be taken into account in evaluation processes, such as geographical dispersion. The fact that VCoP rely on Information and Communication Technologies (ICT) to execute their practices as well as storing artifacts virtually makes more consistent data analysis possible; thus, the evaluation process can apply automatic data gathering and analysis. Methodology: A systematic mapping study, based on five research questions, was carried out in order to analyze existing studies about VCoP evaluation methods and frameworks. The mapping included searching five research databases resulting in the selection of 1,417 papers over which a formal analysis process was applied. This process led to the preliminary selection of 39 primary studies for complete reading. After reading them, we select 28 relevant primary studies from which data was extracted and synthesized to answer the proposed research questions. Contribution: The authors of the primary studies analyzed along this systematic mapping propose a set of methods and strategies for evaluating VCoP, such as frameworks, processes and maturity models. Our main contribution is the identification of some research gaps present in the body of studies, in order to stimulate projects that can improve VCoP evaluation methods and support its important role in social learning. Findings: The systematic mapping led to the conclusion that most of the approaches for VCoP evaluation do not consider the combination of data structured and unstructured metrics. In addition, there is a lack of guidelines to support community operators’ actions based on evaluation metrics.

Background: Magnetic Resonance Imaging (MRI) plays an important role in the field of medical diagnostic imaging as it poses non-invasive acquisition and high soft-tissue contrast. However, the huge time is needed for the MRI scanning process that results in motion artifacts, degrades image quality, misinterpretation of data, and may cause uncomfortable to the patient. Thus, the main goal of MRI research is to accelerate data acquisition processing without affecting the quality of the image. Introduction: This paper presents a survey based on distinct conventional MRI reconstruction methodologies. In addition, a novel MRI reconstruction strategy is proposed based on weighted Compressive Sensing (CS), Penalty-aided minimization function, and Meta-heuristic optimization technique. Methods: An illustrative analysis is done concerning adapted methods, datasets used, execution tools, performance measures, and values of evaluation metrics. Moreover, the issues of existing methods and the research gaps considering conventional MRI reconstruction schemes are elaborated to obtain improved contribution for devising significant MRI reconstruction techniques. Results: The proposed method will reduce conventional aliasing artifacts problems, may attain lower Mean Square Error (MSE), higher Peak Signal-to-Noise Ratio (PSNR), and Structural SIMilarity (SSIM) index. Conclusion: The issues of existing methods and the research gaps considering conventional MRI reconstruction schemes are elaborated to devising an improved significant MRI reconstruction technique.

: Because of the consistently expanding energy request, the introduction of a decentralized micro-grid based on energy resources will soon be the most exciting development in the power system. Micro-grids, which are mainly based on inverters, are becoming more popular as they can handle different forms of renewable energy effectively. However, one of the most challenging areas of research is their control. In the last few years, many control strategies have been developed. In this review, different control methods have been discussed that apply to the micro-grid system. Furthermore, the comparative analysis of classical and modern control strategies is also considered. This survey guides the new researchers about all available control strategies and room for improvement towards the optimal solution of the micro-grid control techniques. It also identifies several research gaps and future trends therein as well as provides a solution to manage problems in MGs. The strategies are then compared based on their applicability to different control requirements.

For anyone interested in wildlife, birds, wilderness areas, parks, ecology, conservation, environmental literature, and ethics, the name Aldo Leopold is sure to pop up. Since first publication, Aldo Leopold: A Fierce Green Fire has remained the classic short, inspiring biography of Leopold--the perfect companion to reading his ever popular A Sand County Almanac. Winning numerous awards, this comprehensive account of his life story is dynamic and readable, written in the context of the history of American conservation and illustrated with historic photographs. Marybeth Lorbiecki has now enriched A Fierce Green Fire in a way no other biography on Leopold has, adding numerous chapters on the ripple effects of his ideas, books, ecological vision, land ethic, and Shack, as well as of the ecological contributions of his children, graduate students, contemporary scholars, and organizations--and the wilderness lands he helped preserve. Lorbiecki weaves these stories and factual information into the biography in a compelling way that keeps both lay and academic readers engaged. In the introduction to this edition, Lorbiecki makes it clear how much better our lives are because Leopold lived and why today we so radically need what he left us to bring about paradigm shifts in our ethical, economic, and cultural thinking. Instead of losing relevance, Leopold's legacy has gained ever more necessity and traction in the face of contemporary national and world challenges, such as species loss and climate change. Even the phenological studies he started at as a hobby are proving valuable, showing the climatic shifts that have occurred at the Shack lands since the 1930s, recognized by the plants and animals.

Abstract Objective The current study aimed at investigating the contribution of researchers in the Arab region to the field of mental health and well-being of university students using bibliometric tools. Method Relevant literature was obtained from the Scopus database for the period from 2001–2020. Examples of keywords used in the query included “college student”, “university student”, and undergraduate student” combined with keywords such as wellbeing, wellness, suicide, and anxiety. No language restriction was used. Only research articles were considered. The search query was validated. Bibliometric indicators and mappings such as active countries, institutions, authors, highly cited documents, and the most frequently encountered topics were identified and discussed to shed light on research gaps in the Arab region. Research gaps were also identified. The analysis was carried out on February 12, 2021. Results The search query returned 309 research articles published by authors from 17 different Arab countries. Less than one-third (n = 97, 31.4%) of the retrieved articles were carried out in collaboration with authors from 39 non-Arab countries, mainly from the United Kingdom and the United States. The overall contribution of researchers from the Arab region to global research in the field was 5.6%. In total, 1212 authors from 791 different institutions participated in publishing the retrieved research articles. At the country level, Saudi Arabia (n = 125, 40.5%) ranked first, followed by Jordan, Egypt, and Lebanon. At the institutional level, The University of Jordan (n = 25, 8.1%) ranked first, followed by King Saud University, and Kuwait University. The retrieved articles included 132 (42.7%) articles on stress/distress, 95 (30.7%) on anxiety, 61 (19.7%) on depression. Knowledge gaps on suicide, eating disorders, substance use, and happiness were identified. The retrieved articles appeared in 193 different journals and approximately two-thirds of the active journal were in general medicine, public health, and education. Conclusions The contribution of researchers in the Arab region to the field showed a noticeable increase with time. However, important research gaps were identified. The contribution was confined to authors from a limited number of Arab countries. Funding and international research collaboration for the mental health and well-being of students need to be strengthened.

AbstractComa and disorders of consciousness (DoC) are highly prevalent and constitute a burden for patients, families, and society worldwide. As part of the Curing Coma Campaign, the Neurocritical Care Society partnered with the National Institutes of Health to organize a symposium bringing together experts from all over the world to develop research targets for DoC. The conference was structured along six domains: (1) defining endotype/phenotypes, (2) biomarkers, (3) proof-of-concept clinical trials, (4) neuroprognostication, (5) long-term recovery, and (6) large datasets. This proceedings paper presents actionable research targets based on the presentations and discussions that occurred at the conference. We summarize the background, main research gaps, overall goals, the panel discussion of the approach, limitations and challenges, and deliverables that were identified.
