1 Quantum computing in power systems
محاسبات کوانتومی در سیستم های قدرت-2022
Electric power systems provide the backbone of modern industrial societies. Enabling scalable grid analytics is the keystone to successfully operating large transmission and distribution systems. However, today’ s power systems are suffering from everincreasing computational burdens in sustaining the expanding communities and deep integration of renewable energy resources, as well as managing huge volumes of data accordingly. These unprecedented challenges call for transformative analytics to support the resilient operations of power systems. Recently, the explosive growth of quantum computing techniques has ignited new hopes of revolutionizing power system computations. Quantum computing harnesses quantum mechanisms to solve traditionally intractable computational problems, which may lead to ultra-scalable and efficient power grid analytics. This paper reviews the newly emerging application of quantum computing techniques in power systems. We present a comprehensive overview of existing quantum-engineered power analytics from different operation perspectives, including static analysis, transient analysis, stochastic analysis, optimization, stability, and control. We thoroughly discuss the related quantum algorithms, their benefits and limitations, hardware implementations, and recommended practices. We also review the quantum networking techniques to ensure secure communication of power systems in the quantum era. Finally, we discuss challenges and future research directions. This paper will hopefully stimulate increasing attention to the development of quantum-engineered smart grids.

2 Advanced digital forensics and anti-digital forensics for IoT systems: Techniques, limitations and recommendations
پزشکی قانونی دیجیتال پیشرفته و پزشکی قانونی ضد دیجیتال برای سیستم های اینترنت اشیا: تکنیک ها، محدودیت ها و توصیه ها-2022
Recently, the number of cyber attacks against IoT domains has increased tremendously. This resulted into both human and financial losses at all IoT levels especially individual and organization levels. Recently, cyber-criminals have kept on leveraging new skills and capabilities by conducting anti-forensics activities and employing techniques and tools to cover their tracks to evade any possible detection of the attack’s events, which has targeted either the IoT system or/and its component(s). Consequently, IoT cyber-attacks are becoming more efficient and more sophisticated with higher risks and threat levels based on their more frequent likelihood to occur and their impact. However, traditional security and forensics solutions are no longer enough to prevent nor investigate such cyber attacks, especially in terms of acquiring evidence for attack investigation. Hence, the need for well-defined, sophisticated, and advanced forensics investigation techniques is highly required to prevent anti-forensics techniques and track down cyber criminals. This paper reviews the different forensics and anti-forensics methods that can be applied in the IoT domain including tools, techniques, types, and challenges, while also discussing the rise of the anti-anti-forensics as a new forensics protection mechanism against anti-forensics activities. This would help forensics investigators to better understand the different anti-forensics tools, methods and techniques that cyber criminals employ while launching their attacks. Moreover, the limitations of the current forensics techniques are discussed, especially in terms of issues and challenges. Finally, this paper presents a holistic view from a literature point of view over the forensics domain in general and for IoT in particular.

3 Pain management for infants – Myths, misconceptions, barriers; knowledge and knowledge gaps
مدیریت درد برای نوزادان - افسانه ها، باورهای غلط، موانع؛ دانش و شکاف دانش-2021
Twelve years ago, the paper ‘Oral sucrose for pain management in infants: Myths and misconceptions’ was published in the Journal of Neonatal Nursing. At this time, eight myths or misconceptions were addressed. Since this time there has been more than 100 studies published reporting on analgesic effects of sweet solutions in newborns, which have been synthesised and included in systematic reviews. There has also been a growth of literature to support analgesic effects of breastfeeding and skin-to-skin care as well as concerning evidence of adverse long-term neurobehavioural outcomes associated with painful procedures. Yet, ongoing studies of pain management practices continue to report inconsistent use of these strategies during painful procedures. We are therefore at a cross-roads of evidence – there is knowledge of effective treatments, knowledge of harm of untreated pain, yet sick, premature as well as healthy infants are continuing to be exposed to painful procedures with no effective treatment. There are however ongoing myths, misconceptions, and practical barriers to using the evidence as well as ongoing knowledge gaps. This paper will therefore highlight existing myths, misconceptions, barriers and current knowledge gaps to using the three key evidence-based pain management strategies of breastfeeding, skin-to-skin care and sweet solutions, in the hope that this will bring to light newborn infant pain treatment practices that can be improved.

4 Wood supply chain risks and risk mitigation strategies: A systematic review focusing on the Northern hemisphere
خطرات زنجیره تامین چوب و استراتژی های کاهش خطر: یک مرور سیستماتیک با تمرکز بر نیمکره شمالی-2021
This paper presents a systematic literature review on both the risks affecting wood supply security and risk mitigation strategies by quantitative and qualitative data analysis. It describes wood-specific supply chain risks, thereupon resulting impacts and counteracting strategies to ensure supply. Risks, impacts, and strategies are documented as basis for a comparative analysis, discussion of results, challenges and research gaps. Finally, the suitability and the limitations of the chosen methodology and the achieved results are discussed. Scanning wood supply chain risks and supply strategies, most of the reviewed papers focus on wood supply for bioenergy generation and only a few studies investigate wood supply chain risk issues for the sawing, wood panel, pulp and paper industries, or biorefineries.This review differs significantly from other reviews in this field as it considers the entire wood value chain including recent studies on new chemical wood-based products and thus provides a more complete picture of the wood-based bioeconomy. Consequently, it contributes to the literature by providing an overarching investigation of the risks affecting wood supply security and possible side effects of a growing wood-based bioeconomy. It was found that comprehensive value chain analyses considering established wood products, large-volume bioenergy products, as well as established and new chemical wood-based products in the context of wood supply security are missing. Studies that map the entire wood value chain with its multilevel interdependences and integrating cascading use of wood are lacking.

5 COVID-19 pandemic related supply chain studies: A systematic review
مطالعات زنجیره تامین مرتبط با همه گیری COVID-19 : مرور سیستماتیک-2021
The global spread of the novel coronavirus, also known as the COVID-19 pandemic, has had a devastating impact on supply chains. Since the pandemic started, scholars have been researching and publishing their studies on the various supply-chain-related issues raised by COVID-19. However, while the number of articles on this subject has been steadily increasing, due to the absence of any systematic literature reviews, it remains unclear what aspects of this disruption have already been studied and what aspects still need to be investigated. The present study systematically reviews existing research on the COVID-19 pandemic in supply chain disciplines. Through a rigorous and systematic search, we identify 74 relevant articles published on or before 28 September 2020. The synthesis of the findings reveals that four broad themes recur in the published work: namely, impacts of the COVID-19 pandemic, resilience strategies for managing impacts and recovery, the role of technology in implementing resilience strategies, and supply chain sustainability in the light of the pandemic. Alongside the synthesis of the findings, this study describes the methodologies, context, and theories used in each piece of research. Our analysis reveals that there is a lack of empirically designed and theoretically grounded studies in this area; hence, the generalizability of the findings, thus far, is limited. Moreover, the analysis reveals that most studies have focused on supply chains for high-demand essential goods and healthcare products, while low-demand items and SMEs have been largely ignored. We also re- view the literature on prior epidemic outbreaks and other disruptions in supply chain disciplines. By considering the findings of these articles alongside research on the COVID-19 pandemic, this study offers research questions and directions for further investigation. These directions can guide scholars in designing and conducting impactful research in the field.

6 Distribution channel and licensing strategy choice considering consumer online reviews in a closed-loop supply chain
کانال توزیع و انتخاب استراتژی صدور مجوز با در نظر گرفتن بررسی های آنلاین مصرف کنندگان در یک زنجیره تامین حلقه بسته-2021
This research builds two-period game models to address the choice issues of the Original Equipment Manufacturer (OEM)’s licensing strategy and the Independent Remanufacturer (IR)’s distribution channel, considering consumer online reviews in a closed-loop supply chain. In both periods, the OEM sells new products by the direct distribution channel. In period 2, the OEM determines the licensing strategy (the fixed or royalty fee) to authourize the IR to remanufacture, and then the IR chooses the distribution channel (direct or indirect) for remanufactured products. Interestingly, our results show that the IR prefers the direct channel when the remanufacturing cost is smaller. And the obtained willingness-to-pay (WTP) from consumer online reviews has a positive impact on the threshold value of the remanufacturing cost. Moreover, we find that the OEM’s licensing strategy choice depends on the sizes of the fixed licensing fee and the obtained WTP. The OEM will choose the royalty licensing strategy to the IR who has chosen the direct channel, when the fixed fee and the obtained WTP are smaller. Finally, we find the optimal royalty fee, numerically examine the impact of the interaction among these factors on consumer surplus and social welfare, and relax the basic assumption to show the robustness of our model.

7 Knowledge management and humanitarian organisations in the Asia-Pacific: Practices, challenges, and future pathways
مدیریت دانش و سازمان های بشردوستانه در آسیا و اقیانوس آرام: شیوه ها، چالش ها و مسیرهای آینده-2021
While there is growing recognition amongst humanitarians that knowledge sharing and exchange are essential components of organisational efficiency and effectiveness, knowledge management processes in many human- itarian organisations are still inadequate. The review of knowledge management and international relations literature reveals limited research on the institutional memory of humanitarian organisations. This article aims to start filling this research gap by examining the use of explicit and tacit knowledge transfer in the humanitarian sector in the Asia-Pacific. It points to the embryonic stage of knowledge management and the reliance on tacit knowledge management consistent with the early stage of sector professionalization in the region. It reviews and analyses existing scholarly literature and manuals and draws on fieldwork interviews with key humanitarian personnel that primarily focus on natural hazards. The findings suggest institutional memory in the humanitarian sector remains ad hoc with limited long-term capture. There is a broad tendency in the region to rely on tacit knowledge transfer – interpersonal relationships and informal decision-making – as the dominant knowledge management practice. This reliance challenges knowledge management at the institutional level and indicates a weakness in the institutional memory of humanitarian organisations in the region. Our research raises questions about how to improve knowledge management practices within humanitarian organisations in the Asia-Pacific with significant implications for the sector more generally. A recalibration of tacit and explicit knowledge management would build institutional memory in humanitarian organisations. This requires a dual-track approach with codified documentation of experiences and greater emphasis on an institutional culture of knowledge sharing.

8 Disaster management training in the euregio-meuse-rhine: What can we learn from each other to improve cross-border practices?
آموزش مدیریت بلایا در euregio-meuse-rhine: برای بهبود شیوه های فرامرزی چه چیزی می توانیم از یکدیگر بیاموزیم؟-2021
Increasing numbers of disasters require comprehensive preparedness. Border regions are vulnerable as disasters might not halt at administrative borders. Cross-border coordination is therefore required. As integral part of cross-border collaborations initiative in the Meuse–Rhine Euregio (EMR), we reviewed published evidence informing on existing initiatives dedicated to disaster education in the EMR. A search based on the PRISMA guidelines for scoping reviews was conducted to retrieve articles in the following databases: Medline, PsychInfo and Scopus. The searches were limited to English, French, Dutch and German language articles and the period between January 2010 and June 2019. No restrictions were set for the study design or the type of methodology used. A total of 18 articles met the inclusion criteria out of a total of 1771 publications. Training development was found in two studies while nine studies focused on the state of knowledge in disaster management. Seven articles referred only to technical skills, three only to non-technical skills and eight combined both types of skills. For the technical nature, Knowledge was found seven times, Skills five times and Attitudes twice. On the non- technical side, Knowledge was found three and both Skills twice and Attitudes three times. Five studies trained and assessed all the Knowledge, skills and attitudes. Most of the studies constitute inventories with descriptive reporting and very few experimental studies of quality have been carried. Non-technical skills for disaster preparedness have been well considered among the articles. Cross-border collaboration needs to be further investigated.

10 Chapter 34: Indigenous knowledge in research and management
فصل 34: دانش بومی در تحقیق و مدیریت-2021
Experience and insight have been a source of knowledge throughout human history. Only in the past few centuries have scientific methods been developed and applied to questions of practice and theory. Even today, experiential knowledge is far broader than the relatively limited scope of rigorous scientific research. Such knowledge is known by many names, including Indigenous Knowledge (IK, which will be used herein), traditional knowledge, local knowledge, and other variants (Huntington and Fox, 2005). For Indigenous whale hunters in the Arctic, the knowledge gained by experience is paramount for safety and success (e.g., Nageak, 1991). Although visitors and newcomers to the Arctic have long relied on Indigenous assistance (e.g., Amundsen, 1908), only in recent decades has the knowledge of whalers and other practitioners elsewhere in the world attracted formal academic attention (e.g., Johannes, 1981; Mymrin, 1999; Hay et al., 2000). Indeed, the collaborations between In˜upiat and Yupik whalers and scientists in northern Alaska are among the best examples of sharing knowledge and developing new knowledge beyond the capabilities of either group alone. This chapter reviews the ways that scientists and managers have engaged with the knowledge of Arctic whalers, what has been learned thereby, and how the resulting knowledge has contributed to understanding and management of bowhead whales (Fig. 34.1).
