One of the rallying cries of the blockchain community is that of immutability: the irreversibility of the past, the absolute truth which, once stored, remains there forever. The technology was designed with this foundational pillar in mind to ensure that changes to history are inordinately expensive and practically impossible to execute – and increasingly so, the further in the past the event which one intends to manipulate lies. This platonic view of absolute truth is in stark contrast with a world of manipulated truth, and it is not surprising that it is being revisited as a means of combating fake news. We argue that claims to the absolute nature of the blockchain are at best exaggerated, at worst misrepresented or even ‘fake news’. We discuss implicit centralised points of trust in blockchains, whether at a technological, social or governance level, and identify how these can be a threat to the ‘immutable truth’ stored within the blockchain itself. A global pandemic has unleashed an unprecedented wave of contradictory positions on anything from vaccines and face masks to ‘the new normal’. It is only natural that the pursuit of blockchain as a placebo for society's ‘truth’ problems continues.

We propose a generic algorithm for numerically accurate likelihood evaluation of a broad class of spatial models characterized by a high-dimensional latent Gaussian process and non-Gaussian response variables. The class of models under consideration includes specifications for discrete choices, event counts and limited-dependent variables (truncation, censoring, and sample selection) among others. Our algorithm relies upon a novel implementation of efficient importance sampling (EIS) specifically designed to exploit typical sparsity of high-dimensional spatial precision (or covariance) matrices. It is numerically very accurate and computationally feasible even for very high-dimensional latent processes. Thus, maximum likelihood (ML) estimation of high-dimensional non-Gaussian spatial models, hitherto considered to be computationally prohibitive, becomes feasible. We illustrate our approach with ML estimation of a spatial probit for US presidential voting decisions and spatial count data models (Poisson and Negbin) for firm location choices.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

EVERYONE today is busily engaged in devising new methods, bringing about economies in motions, and applying incentives, but is enough attention being paid to the maintenance mechanics, from the human aspect, in these applications of work study?

The mid-1990s marked a paradigm shift in the way physical activity is promoted, and walking is now considered the most suitable type of physical activity for widespread promotion. Accurate measurement underpins public health practice, hence the aims of this chapter are to: (1) provide a typology for the measurement of walking; (2) review methods to assess walking; (3) present challenges in defining walking measures; (4) identify issues in selecting instruments for the evaluation of walking and (5) discuss current efforts to overcome measurement challenges and methodological limitations. The taxonomy of walking indicates that secondary purpose walking is a more complex set of behaviours than primary purpose walks. It has many purposes and no specific domain or intensity, may lack regularity, and therefore poses greater measurement challenges. Objective measurement methods, such as accelerometers, pedometers, smartphones and other electronic devices, have shown good approximation for walking energy expenditure, but are indirect methods of walking assessment. Global Positioning System technology, the ‘Smartmat’ and radio-frequency identification tags are potential objective methods that can distinguish walkers, but also require complex analysis, are costly, and still need their measurement properties corroborated. Subjective direct methods, such as questionnaires, diaries and direct observation, provide the richest information on walking, especially short-term diaries, such as trip records and time use records, and are particularly useful for assessing secondary purpose walking. A unifying measure for health research, surveillance and health promotion would strongly advance the understanding of the impact of walking on health.

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

This chapter provides an extensive review of literature on the interaction between and interdependence of informal and formal working practices in various workplace settings. The aim of the chapter is to elucidate the organisational, managerial, human relations and social factors that give rise to informal work practices and strategies, on the shop-floor not only at workers and work group levels but also at supervisory and managerial levels. This chapter helps the reader to understand the informal work practice of making a plan (planisa) in a deep-level mining workplace.

David Gordon’s early work included a focus on cities and their role in capitalist development, but he didn’t complete or publish an ambitious project called CAPITALopolis. Gordon instead developed a framework linking Marxian insights with historical analysis of institutional impact and change through his social structures of accumulation framework. Subsequent mainstream and radical urban analyses didn’t use Gordon’s work, but his early writings are consistent with his passion for fighting racial and economic inequality, and understanding those forces systematically as part of the history and logic of capitalism.
