1 Costs of resilience and disruptions in supply chain network design models: A review and future research directions
هزینه های انعطاف پذیری و اختلالات در مدل های طراحی شبکه زنجیره تامین: یک مرور و دستورالعمل های آینده تحقیق-2021
Supply chain network design (SCND) is a key strategic decision in supply chain management (SCM). One particular area of SCND is concerned with disruption risk modelling. This paper presents a systematic literature review of quantitative models of SCND under disruption risks in industrial SCM and logistics. More specifically, our analysis is focused on different costs induced by the planning of proactive investments in robustness and through parametrical/structural adaptation at the recovery stage. This review can be of value for researchers and decision-makers alike for several reasons. First, we categorise the existing knowledge based on decision-making problems, which can be instructive for a convenient association of a particular SCND problem to a modelling domain according to network-wise, supply-side and demand-side perspectives. Second, our analysis focuses on the costs specifically induced by disruption risks and resilience investments. Third, we offer a dedicated section related to disruption probability formulation methods and their impact on resilience costs. Fourth, the integration of different SCM dimensions (i.e., social impact, environmental impact, responsiveness, and risk- aversion) and the associated multi-objective modelling settings are discussed along with disruption risks in SCND models. Finally, we summarize our findings as insights from a managerial perspective. Drawbacks and missing aspects in the related literature are highlighted, and we lay out several research directions and open questions for future research.

2 Knowledge, attitude, and practice of forensic practitioners during COVID-19 pandemic in Arab countries
دانش، نگرش و عملکرد پزشکان قانونی در طول همه گیری COVID-19 در کشورهای عربی-2021
COVID-19 pandemic burdens forensic practice worldwide. The experience of crisis management is a lesson learned that guides future preparedness for similar casualties. Thus, the present study takes an in-depth look at the knowledge, attitude, and practice of forensic practitioners during the COVID-19 pandemic in the Arab world. A comprehensive questionnaire was adopted in compliance with optimum international standards for the management of deaths during the pandemic. The survey was electronically distributed in 13 Arab countries. The responses were received from 29 forensic practitioners from 11 countries. Total median knowledge, attitude, and practice scores of respondents constituted 37.9%, 74%, and 36.8% of optimum scores respectively. Regarding knowledge, better scores are related to risk assessment and routes of exposure to Coronavirus, whereas, least scores were related to ventilation and negative pressure system. Most of the participants had a positive attitude, 85.2% were concerned about proper management of COVID-19 deaths, and 77.8% trusted the decisions of their teams. Considering practice, better scores are related to forensic staff competence, whereas, least scores were related to the implementation of ideal safety measures. Participants described the management process as useful (52%), reliable (35%), high quality (21%), and cost-effective (17%), however, they expressed challenges as staff infection, limited resources, and infrastructure issues. This survey guides readjusting of procedures and future preparedness for similar disasters in the Arab world. This research adopted a questionnaire that could be used in initial and periodic assessments in any medicolegal institute worldwide. Also, it could support infrastructure projects and disaster management plans.

3 How has the Covid19 pandemic impacted the courts of law? Evidence from Brazil
همه گیری کووید 19 چگونه بر دادگاه های حقوقی تأثیر گذاشته است؟ شواهدی از برزیل-2020
We provide empirical insight into the consequences of the Covid19 pandemic for the administration of justice. Drawing on a comprehensive monthly panel of Brazilian labor courts and using a differencein-difference approach, we show that the pandemic has had a large and persistent deleterious effect on adjudicatory efficacy, leading to a massive decrease in the clearance rate and an increase in court backlogs. The pandemic has affected how courts dispose adjudication cases, expectedly causing a plummeting in the share of disputes resolved via trial hearings and, less predictably, exerting a temporally non-linear effect on the share of in-court settlements. Notably, we find no evidence of an effect of the pandemic on efficacy in enforcement. Although the pandemic led to an increase in the share of new filings requiring enforcement, any effect on the relative use of enforcement to execute court-ordered payments has been intermittent and temporary. The intensity of the pandemic has been an important moderating factor.

4 Isolating residents including wandering residents in care and group homes: Medical ethics and English law in the context of Covid-19
منزوی کردن ساکنان از جمله ساکنان سرگردان در خانه های مراقبتی و گروهی: اخلاق پزشکی و قانون انگلیس در زمینه کووید-19-2020
This article investigates the lawfulness of isolating residents of care and group homes during the COVID-19 pandemic. Many residents are mobile, and their freedom to move is a central ethical tenet and human right. It is not however an absolute right and trade-offs between autonomy, liberty and health need to be made since COVID-19 is highly infectious and poses serious risks of critical illness and death. People living in care and group homes may be particularly vulnerable because recommended hygiene practices are difficult for them and many residents are elderly, and/or have co-morbidities. In some circumstances, the trade-offs can be made easily with the agreement of the resident and for short periods of time. However challenging cases arise, in particular for residents and occupants with dementia who‘wander’, meaning they have a strong need to walk, sometimes due to agitation, as may also be the case for some people with developmental disability (e.g. autism),or as a consequence of mental illness.This article addresses three central questions: (1) in what circumstances is it lawful to isolate residents of social care homes to prevent transmission of COVID-19, in particular where the resident has a strong compulsion to walk and will not, or cannot, remain still and isolated? (2) what types of strategies are lawful to curtail walking and achieve isolation and social distancing? (3) is law reform required to ensure any action to restrict freedoms is lawful and not excessive? These questions emerged during the first wave of the COVID-19 pandemic and are still relevant. Although focussed on COVID-19, the results are also relevant to other future outbreaks of infectious diseases in care and group homes. Likewise, while we concentrate on the law in England and Wales, the analysis and implications have international significance.

5 The prospects of waste management in the hospitality sector post COVID-19
چشم انداز مدیریت پسماند در بخش مهمان نوازی پس از COVID-19-2020
COVID-19 has imposed significant detrimental effects on the global hospitality sector. These effects have pri- marily been considered from the socio-economic perspective, ignoring the implications of the pandemic for the environmental performance of hospitality services. By drawing upon emerging evidence from various academicand non-academic sources, this conceptual paper critically evaluates the implications of the preventative and protective measures adopted against COVID-19 for the generation of the hospitality sector’s food and plastic waste. The implications are divided into direct and indirect and considered through the prism of temporality oftheir anticipated occurrence (immediate, short-term and medium-term perspective). The paper proposes po- tential strategies to aid in the management of these wastes in the hospitality sector in a post-pandemic world. To address the issue of food waste, the hospitality sector should be integrated into alternative food networks (AFNs) and short food supply chains (SFSCs). Business coopetition between hospitality enterprises and other actors of the food supply chain is necessary for the success of such integration. To address the issue of plastic waste, thehospitality sector should invest in ‘green’ innovation. This investment needs to be encouraged and supported bytargeted policy interventions. The paper argues that these strategies are critical not only in the context of the COVID-19 pandemic, but will also remain valid for the sustained development of the hospitality sector in light of future disastrous events, especially climate change. The paper discusses the institutional and organisational prerequisites for the effective implementation of these strategies and highlights the related research opportunities.
