The analysis designates that Kumar A. has been the most influential author in perishable goods supply chain research during the COVID-19 pandemic, and India has contributed the most in this field. The most repeated keywords were resilience, food supply, and perishable food supply chain. Citation analysis indicated that resilience and sustainability are the mainstream of research in articles with high citations. The network analysis also disclosed that resilience and sustainability are the key themes in the clusters.

The coronavirus pandemic has compelled academic institutions across the globe to initiate online teaching, impacting thereby the teaching-learning process to undergo a structural change. Among various pedagogical techniques that have been adopted, organizing synchronous classes has been found to be the most beneficial. It simulates the classroom environment, facilitating thereby parallel knowledge dissemination to a broader audience. This study measures the efficacy of synchronous web-based learning during this ongoing pandemic, among postgraduate Library and Information Science (LIS) students of Bangladesh. Using an online questionnaire, a survey was conducted among the postgraduate students of the Department of Information Science Library Management (ISLM) of the University of Dhaka. The results revealed that limitation of internet data, unstable internet, along with power blackouts were some of the primary inhibitors blocking the participants to attend classes online. Finally, this study concludes that as most students do not seem to be ready yet to study in a synchronous delivery mode, it recommends educational institutions in Bangladesh to provide an alternative delivery method, in order to sustain academic excellence in these challenging times.

INTRODUCTION: An earthquake is a major natural disaster with widespread and great effects on human life and nature. Taking care of the basic needs of earthquake victims is an essential step that should be addressed immediately. Moreover, the evaluation of various problems after disasters, especially earthquakes, is of crucial importance for the affected people. The management of humanitarian aid and public assistance among these affected people is considered one of the most important post-earthquake concerns. Therefore, the present study was conducted to evaluate the post-earthquake challenges and strengths of providing humanitarian aid services in Sisakht, Yasuj, in February 2019. METHODS: This qualitative case study was conducted from March 2019 to July 2020. The studied population consisted of 20 participants including medical staff (n=10), clergy (n=2), crisis managers (n=4), and military personnel (n=4). The required data were collected through observation and semi-structured interviews, which continued until data saturation. To evaluate the reliability of the data, the strategies recommended by Guba were used. The data were analyzed by conventional content analysis based on the method proposed by Graneheim and Lundman. FINDINGS: The advantages and strengths of this study included humanitarian cooperation and coordination, as well as the timely presence of relief and rescue teams and law enforcement agencies from the post-earthquake first hours, which had a great impact on reducing the suffering of people. The challenges in providing post-earthquake services included health, medical, management, geographical, and spatial concerns and issues related to the earthquake victims (relief goods distribution problem and inappropriate information dissemination as the main challenges). CONCLUSION: Effective and appropriate management policies regarding the management of providing post-earthquake services and elimination of the structural and managerial obstacles can improve the operation and management of humanitarian aid.
