We resolve parts (A) and (B) of Problem 1.100 from Kirby’s list [Problems in low-dimensional topology, in Geometric topology, AMS/IP Studies in Advanced Mathematics, vol. 2 (American Mathematical Society, Providence, RI, 1997), 35–473] by showing that many nontrivial links arise as cross-sections of unknotted holomorphic disks in the four-ball. The techniques can be used to produce unknotted ribbon surfaces with prescribed cross-sections, including unknotted Lagrangian disks with nontrivial cross-sections.

Chain Level

Health crises have an impact on supply chains, mainly by disrupting their regular activities. In this research, the authors have analyzed the impact that the Covid-19 pandemic has made on business relationships between supply chain partners in the automotive industry and their suppliers, which are mostly from territories where the initial outbreak of the SARS COV 2 virus occurred. The analysis shows that in some cases, there is a strong dependency between the pandemic and production levels. Being dependent prevents supply chains from maintaining stability and causes system vulnerabilities. The authors conclude their work with a thesis on the pronounced impact of the current pandemic on automotive supply chain activities. For the analysis to be complete, it is necessary to monitor changes in production levels further, since data for the current year still does not provide a realistic insight into all the consequences at the supply chain level.

Sustainability has assumed increased importance in view of the international focus on pollution control and climate change. Specifically, the development of sustainable supply chain can help in important ways to reduce pollution and address environmental concerns. Energy efficiency forms an important aspect of this movement towards sustainable supply chain. Energy efficiency can be achieved through judicious energy management initiatives at the supply chain level. A metrics-based approach provides an effective mechanism to implement energy management programs in supply chain operation. The chapter explores the utility of energy balance sheet as a metric to implement such energy management programs. It further looks at the challenges and opportunities faced by supply chain partners in implementing energy management programs. It uses the case study of Firozabad glass industry to illustrate the implementation of energy management for developing sustainable supply chain.

This paper builds on research presented by the authors at IRMA 2001. Previous research by Chau and Turner (2001b) adapted the work of Venkatraman (1994) to explore the relationship between the degree of SME organisational transformation and potential benefits derived from e-commerce. The qualitative data explored reveals various factors that influence SME’s ability to derive benefit from conducting Web-based e-commerce. A preliminary review suggests that these factors can be distinguished into internal factors (organisational and technological) and external factors (nature of supply chain, level of service provided by third party organisations, industry influence, and government assistance). This paper discusses these factors and their implications for modelling e-business organisational transformation.
