Abstract
Purpose
The purpose of this paper is to investigate the suitability of Blockchain technology for applications in the Industrial Internet of Things (IIOT). It provides a taxonomy of system requirements for such applications and maps these requirements against the Blockchain’s technological idiosyncrasies.
Design/methodology/approach
A requirement taxonomy is built in an iterative process based on a descriptive literature review. In total, 223 studies have been screened leading to a relevant sample of 48 publications that were analyzed in detail regarding posed system requirements. Subsequently, Blockchain’s capabilities are discussed for each requirement dimension.
Findings
The paper presents a taxonomy of six requirement dimensions. In the mapping process, areas of greater fit (e.g., reliability, nonrepudiation and adaptability) were identified. However, there are also several constraints (e.g., scalability, confidentiality and performance) that limit the use of Blockchain.
Research limitations/implications
Due to the limited amount of studies and the vibrant development of Blockchain technology, the results may benefit from practical evidence. Researchers are encouraged to validate the results in qualitative practitioner interviews. Focusing on literature-backed public Blockchain, idiosyncrasies of private implementations and specific distributed ledger technologies may be discussed in future studies.
Practical implications
The paper includes use cases for Blockchain in manufacturing and IIOT applications. Potential caveats for practitioners are presented.
Originality/value
This paper addresses the need to understand to which degree Blockchain is a suitable technology in manufacturing, especially in context of the IIOT. It contributes a requirement taxonomy which serves as the foundation for a systematic fit assessment.

Abstract
The nature of communication between machines and people is contrasted and the power of words, concepts, and models as metaphors, both to help and to hinder thinking, is discussed. The article observes how every human artefact manifests its own grammar, rhetoric, and logic, and tends to resume the character of spoken natural language through electric speed‐up. It is emphasised that new acoustic‐space process patterns, created by the electric communication environment, are superseding old visual‐space ground rules of the mechanical world. The article then considers how to harmonise these conflicting, but complementary, “natural” orders by learning to anticipate the material, mental, and social effects of our artefacts as human communication media.

Abstract
By the time these pages appear Christmas will have become but a memory; even the indigestion provoked in many of us by our zealous participation in the Christmas spirit will, it is hoped, have become a thing of the past. But as we write this spirit is abroad, and presents are still depleting our surplus finances. Every year more and more of these seasonable gifts take the form of books, and a very large percentage of children, particularly, will surely receive some reading matter from one or other of their friends or relations. Not so many years ago in most instances this Christmas book would be the only volume those children would see that year! Fortunately, we librarians can say, with Sganarelle, that “we have changed all that.” Our children's libraries throughout the country are sufficiently adequate to ensure that no child in a library area is unable to read to his or her heart's content—the days when three or four books must needs satisfy a child's thirst for reading have now been put definitely behind us.

Abstract
A senior analyst has recently completed an on-site visit to the Las Vegas properties of MGM Mirage. She must value the enterprise after her preparation of projected financial statements. Assumptions for these statements come from a combination of standard account relations delineated in the case and from specific company projections that must be gleaned from MGM's MD&A. This case introduces students to pro forma financial statements and their relevance to cash flow and earnings-based valuation. Tools relevant to spreadsheet modeling can also be introduced. The case precedes MGM's announced acquisition of Mandalay Bay Corporation in 2004.
