Abstract

Two different ‘a posteriori’ error estimation techniques are proposed in this paper. The effectiveness of the error estimates in adaptive mesh refinement for 2D and 3D electrostatic problems are also analyzed with numerical test results. The post‐processing method employs an improved solution to estimate the error, whereas the gradient of field method utilizes the gradient of the field solution for estimating the ‘a posterior’ error. The gradient of field method is computationally inexpensive, since it solves a local problem on a patch of elements. The error estimates are tested by solving a set of self‐adjoint boundary value problems in 2D and 3D using a hierarchical minimal tree based mesh refinement algorithm. The numerical test results and the performance evaluation establish the effectiveness of the proposed error estimates for adaptive mesh refinement.

Abstract

Purpose

The ability to manage the COVID-19 pandemic is contingent upon the ability to effectively manage its heterogeneous knowledge resources. Knowledge mapping represents a great opportunity to create value by bringing stakeholders together, facilitating comprehensive collaboration and facilitating broader in-depth knowledge sharing and transfer. However, identifying and analysing critical knowledge areas is one of the most important steps when creating a knowledge map. Therefore, the purpose of this paper is to appraise the critical knowledge areas for managing COVID-19, and thereby enhance decision-making in tackling the consequences of the pandemic.

Design/methodology/approach

The methodological approach for this study is a critical literature review, covering publications on knowledge management, knowledge mapping and COVID-19. EBSCOhost, PubMed, Scopus, Science Direct, TRID, Web of Science and Wiley Online Library were searched for full text, peer-reviewed articles written in English that investigated on critical knowledge areas for managing the spread of COVID-19. After full screening, 21 articles met the criteria for inclusion and were analysed and reported.

Findings

The study revealed seven critical knowledge areas for managing the COVID-19 pandemic. These are cleaning and disinfection; training, education and communication; reporting guidance and updates; testing; infection control measures, personal protective equipment; and potential COVID-19 transmission in health and other care settings. The study developed a concept knowledge map illustrating areas of critical knowledge which decision-makers need to be aware of.

Practical implications

Providing decision-makers with access to key knowledge during the COVID-19 pandemic seems to be crucial for effective decision-making. This study has provided insights for the professionals and decision-makers identifying the critical knowledge areas for managing the COVID-19 pandemic.

Social implications

The study advances the literature on knowledge management and builds a theoretical link with the management of public health emergencies. Additionally, the findings support the theoretical position that knowledge maps facilitate decision-making and help users to identify critical knowledge areas easily and effectively.

Originality/value

This study fills gaps in the existing literature by providing an explicit representation of know-how for managing the COVID-19 pandemic. This paper uses an objective and qualitative approach by reviewing related publications, reports and guidelines in the analysis. The concept map illustrates the critical knowledge areas for managing the COVID-19 pandemic.

Abstract

Purpose

The purpose of this paper is to consider the effect of the Prevention of Money Laundering Act (PMLA), 2002 on the property rights of third parties, by evaluating whether the interpretation of the scheme of the PMLA, 2002 results in a deprivation of rights, by virtue of the provision for the provisional attachment of property.[AQ3] In doing so, this paper attempts to consider two sub-categories of third parties that stand affected by §5 of the PMLA, 2002.

Design/methodology/approach

Primarily the authors analyse diverging judgements and case law across various high courts to evaluate the position of law with regards to attachment of property. To reach a precise legal conclusion, the authors consider the composite scheme of the PMLA, 2002 in their analysis.

Findings

It has been concluded that there is a clear lack of judicial cohesion in the interpretation of the PMLA, 2002, and in the absence of a judgement by the Supreme Court of India, enforcement authorities have failed to correctly identify the boundaries of the offence of money laundering, resulting in a dangerous deprivation of rights.

Originality/value

This paper fills a vacuum of detailed scholarship on anti-money laundering provisions in India, while also being contemporaneously relevant, as it considers the effects of the PMLA, 2002 on bona fide economic transactions and secured creditors.

Abstract

Purpose

Researchers and policymakers are figuring out the adaptation technologies to cope with the changing climate. Adaptation strategies for crop production followed by the farmers at selected study locations had ranged from 6-30 per cent only, and this was mainly due to lack of awareness about the actual cost associated with adaptation and non-adaptation of these strategies.

Design/methodology/approach

Hence, this study aims to address the cost of adaptation for rice using joint probability distribution of rainfall and crop prices.

Findings

Cost of adaptation varied from INR2,389 to 4,395/ha for System of Rice Intensification (SRI); INR646 to 1,121/ha for alternate wetting and drying (AWD) and INR8,144 to 8,677/ha for well irrigation (WI), whereas expected cost for not using these technologies has ranged from INR6,976 to 9,172/ha for SRI; INR4,123 7,764/ha for AWD and INR10,825 to 17,270/ha for WI. Hence, promotion of the adaptation technologies itself will minimize the income losses to the farmers.

Research limitations/implications

Even though, there are many ways for farmers (other than technology), to adapt to climate change (such as out-migration to cities, selling farm assets, focus on children’s education, etc.), this report, given the framework of the major research study undertaken, addresses only farm-level adaptation of the technologies to enhance farm income.

Originality/value

Public–private partnership in providing the technologies at cheaper costs, capacity building in handling the technologies and creating awareness about the technologies to minimize the expected cost of adaptation are suggested to improve the adoption level.

Abstract

Learning outcomes

After completion of this case, students would be able to understand the challenges faced by social entrepreneurship in a time of pandemic, as well as gain a perspective of the background, history, evolution and the setup of such organizations; appreciate the role of marketing methods in tackling the challenges faced and how the management of such enterprises could use them on the ground; evaluate possible future options/pathways that could be taken in the backdrop of a pandemic and, more importantly, in a developing country context; and apply the elements of social entrepreneurship theory and suggest a way ahead for ThankUfoods (TUF).

Case overview/synopsis

TUF is a social enterprise that empowers visually and physically challenged people by using while profitably selling food products. Few years of existence, it was facing a major dilemma regarding strategies to continue its existing business and the way forward. Because of the pandemic, the traditional offline business models became redundant on which TUF was heavily dependent. At the same time, TUF had to balance providing support to its employees, staying financially afloat and upholding its parent organization’s core objectives, the India Association for Blind (IAB). IAB was founded to rescue and provide livelihood for specially abled people. TUF was formed as a sister concern that combined charitable work and profit earning to make visually challenged people self-sufficient. At this juncture, the protagonist of the case Mr Abdul Raheem, chief executive officer of TUF and vice president of IAB, approached consultants to chart the way forward. He was forced to explore novel options ranging from conceptual ones, such as setting the right objectives and revisiting mission and vision, to more operational ones, such as venturing into online space, increasing advertisements and achieving breakeven sales. This case study highlights the overall journey of TUF, the underlying constraints, the new challenges faced and the dilemma ahead. Further, it covers the context and challenges peculiar to an emerging market setting. More importantly, it provides a setting for the students to be in the protagonist’s position and ponder – how should a social enterprise functioning in an emerging market function in times of pandemic crises? If it decides to explore novel options, what should be those, how can it proceed, and what to be cautious about.

Complexity academic level

The target audience for the case study are students from MBA and BBA courses, management trainees who are interested to learn about the challenges social entrepreneurship face at the time of crisis. This case study could be used to explain concepts about social entrepreneurship, brand positioning, e-commerce marketing and decision-making in the time of pandemics/crises. The case is also suitable for senior management personnel who participate in executive education programs.
