Abstract
Purpose
(1) A concern often expressed in relation to cryptocurrencies is the environmental impact associated with increasing energy consumption and mining pollution. Controversy remains regarding how environmental attention and public concerns adversely affect cryptocurrency prices. Therefore, the paper aims to introduce the index of cryptocurrency environmental attention (ICEA), which aims to capture the relative extent of media discussions surrounding the environmental impact of cryptocurrencies. (2) The impacts of cryptocurrency environmental attention on long-term macro-financial markets and economic development remain part of undeveloped research fields. Based on these factors, the paper will further examine the effects of the ICEA on financial markets or economic developments.
Design/methodology/approach
(1) The paper introduces a new index to capture cryptocurrency environmental attention in terms of the cryptocurrency response to major related events through gathering a large amount of news stories around cryptocurrency environmental concerns – i.e. >778.2 million news items from the LexisNexis News & Business database, which can be considered as Big Data – and analysing that rich dataset using variety of quantitative techniques. (2) The vector error correction model (VECM) and structural VECM (SVECM) [impulse response function (IRF), forecast error variance decomposition (FEVD) and historical decomposition (HD)] are useful for characterising the dynamic relationships between ICEA and aggregate economic activities.
Findings
(1) The paper has developed a new measure of attention to sustainability concerns of cryptocurrency markets' growth, ICEA. (2) ICEA has a significantly positive relationship with the UCRY indices, volatility index (VIX), Brent crude oil (BCO) and Bitcoin. (3) ICEA has a significantly negative relationship with the global economic policy uncertainty (GlobalEPU) and global temperature uncertainty (GTU). Moreover, ICEA has a significantly positive relationship with the industrial production (IP) in the short term, whilst having a significantly negative relationship in the long term. (4) The HD of the ICEA displays higher linkages between environmental attention, Bitcoin and UCRY indices around key events that significantly change the prices of digital assets.
Research limitations/implications
The ICEA is significant in the analysis of whether cryptocurrency markets are sustainable regarding energy consumption requirements and negative contributions to climate change. Understanding of the broader impacts of cryptocurrency environmental concerns on cryptocurrency market volatility, uncertainty and environmental sustainability should be considered and developed. Moreover, the paper aims to point out future research and policy legislation directions. Notably, the paper poses the question of how cryptocurrency can be made more sustainable and environmentally friendly and how governments' cryptocurrency policies can address the cryptocurrency markets.
Practical implications
(1) The paper develops a cryptocurrency environmental attention index based on news coverage that captures the extent to which environmental sustainability concerns are discussed in conjunction with cryptocurrencies. (2) The paper empirically investigates the impacts of cryptocurrency environmental attention on other financial or economic variables [cryptocurrency uncertainty (UCRY) indices, Bitcoin, VIX, GlobalEPU, BCO, GTU index and the Organisation for Economic Co-operation and Development IP index]. (3) The paper provides insights into making the most effective use of online databases in the development of new indices for financial research.
Social implications
Whilst blockchain technology has a number of useful implications and has great potential to transform several industries, issues of high-energy consumption and CO2 pollution regarding cryptocurrency have become some of the main areas of criticism, raising questions about the sustainability of cryptocurrencies. These results are essential for both policy-makers and for academics, since the results highlight an urgent need for research addressing the key issues, such as the growth of carbon produced in the creation of this new digital currency. The results also are important for investors concerned with the ethical implications and environmental impacts of their investment choices.
Originality/value
(1) The paper provides an efficient new proxy for cryptocurrency and robust empirical evidence for future research concerning the impact of environmental issues on cryptocurrency markets. (2) The study successfully links cryptocurrency environmental attention to the financial markets, economic developments and other volatility and uncertainty measures, which has certain novel implications for the cryptocurrency literature. (3) The empirical findings of the paper offer useful and up-to-date insights for investors, guiding policy-makers, regulators and media, enabling the ICEA to evolve into a barometer in the cryptocurrency era and play a role in, for example, environmental policy development and investment portfolio optimisation.

Abstract
Purpose
This study is motivated in part by the fact that the unfolding 2022 bear market, which has reached the −25% drawdown, has not been preceded by the inverted 10Y-3 m spread or an inverted near-term forward spread.
Design/methodology/approach
The authors develop a three-factor probit model to predict/explain the deep stock market drawdowns, which the authors define as the drawdowns in excess of 20%.
Findings
The study results show that (1) the rising credit risk predicts a deep drawdown about a year in advance and (2) the monetary policy easing precedes an imminent drawdown below the 20% threshold.
Originality/value
This study three-factor probit model shows adaptability beyond the typical recessionary bear market and predicts/explains the liquidity-based selloffs, like the 2022 and possibly the 1987 deep drawdowns.

Abstract
The National Health Campaign organised by the Ministry of Health and the Board of Education, and assisted by the Central Council for Health Education, was heralded, launched and blessed by the Prime Minister on September 30th. It is to be continued for six months; and in March of next year the National Advisory Council for Physical Training and Recreation will direct public attention to the then existing facilities for such training. In the meantime many local authorities, empowered by the Physical Training and Recreation Act, 1937, will form Local Area Committees and provide, assisted by Government grants, recreation centres and facilities for those of all ages. Therefore His Majesty's Government is making an improvement in national physical fitness a fundamental point of policy.

Abstract
Pesaran and Smith (2011) concluded that Dynamic Stochastic General Equilibrium (DSGE) models were sometimes a straitjacket which hampered the ability to match certain features of the data. In this chapter, the authors look at how one might assess the fit of these models using a variety of measures, rather than what seems to be an increasingly common device – the Marginal Data Density. The authors apply these in the context of models by Christiano, Motto, and Rostagno (2014) and Ireland (2004), finding they fail to make a match by a large margin. Both of these models feature more shocks than observed variables, resulting in the empirical shocks having a singular density, and so making them correlated. When correlated one can neither interpret impulse responses nor perform variance decompositions. Against this, there is a strong argument for having a straitjacket, as it enforces some desirable behavior on models and makes researchers think about how to account for any non-stationarity in the data. The authors illustrate this with examples drawn from the SVAR literature and also more eclectic models such as Holston, Laubach, and Williams (2017) for extracting an estimate of the real natural rate.

Abstract
The financial analysis of international investment decisions is complex. The basic methodology which homes in on incremental cash flows needs to be refined in order to focus upon cash flows which are remittable to the parent company, for it is only these that would logically add shareholder value. Build in the complications of two lots of tax and changing exchange rates and the equation looks anything but simple. But there is another complexity too which renders the traditional discounting methodology less than wholly appropriate. And this applies not just to international investment but to any situation where capital is committed with an option to expand or curtail embedded in it. This is not to say that the typical model cannot be adapted to meet the situation. It can and it is not too difficult.

Abstract
DURING most of last month and almost without exception, newspapers and journals, especially those serving trade and industry, have been referring to George Orwell's masterpiece (if that is what it was) almost as though it were divine script. This, despite the fact that at least as far as the magic date is concerned it was completely wrong. His prognostications have proved certainly no better than Nostradamus or Old Moore.

Abstract
An odd‐sounding expression recently introduced into the language, derived from the passage of events, Privatization, introduced as a rescue operation for sections of public and nationalised industry to hand them over to private enterprise to avoid their destruction and smothering by the unholy wedlock of trade unionism and weak, inefficient management. It frequently met with the opposition of unions and sections of staff. Efforts have been made to sabotage the take‐over and operation of the services by private firms, occasionally making them impossible to operate. This elementary operation was expected to achieve even greater success in the sections taken over and reduced the room for destructive manoeuvring by ajitator, much of which was caused independent of the unions. In the public services some of the antics between rival factions bordered on the ludicrous.

Abstract
THE Reference Department of Paisley Central Library today occupies the room which was the original Public Library built in 1870 and opened to the public in April 1871. Since that date two extensions to the building have taken place. The first, in 1882, provided a separate room for both Reference and Lending libraries; the second, opened in 1938, provided a new Children's Department. Together with the original cost of the building, these extensions were entirely financed by Sir Peter Coats, James Coats of Auchendrane and Daniel Coats respectively. The people of Paisley indeed owe much to this one family, whose generosity was great. They not only provided the capital required but continued to donate many useful and often extremely valuable works of reference over the many years that followed. In 1975 Paisley Library was incorporated in the new Renfrew District library service.

Abstract
Purpose
Conceptual advancement underpins the progress of social marketing and countermarketing research but has been neglected in recent years. This paper aims to describe a new integrative framework of social countermarketing (SCM) concepts, techniques and defining characteristics, based on research tracing the conceptual evolution of the field and contrasting commercial (profit-focused) and social (public good-focused) countermarketing.
Design/methodology/approach
This paper undertook searches of electronic databases to examine how socially oriented countermarketing has been characterised in the research literature. Search terms included “countermarketing”, “critical marketing”, “de-marketing” and “counter-advertising”. Broad inclusion criteria allowed consideration of reports, conference and media outputs, as well as peer-reviewed articles published since 1971. Selected marketing journals were searched individually.
Findings
After screening of 408 initial search results, 80 studies were retained and full papers retrieved. Main ideas, definitions, scope, concepts and terms used were mapped to identify the common and distinguishing features, as well as higher-order organising themes. This led to the development of a new conceptual framework for SCM comprising eight domains.
Research limitations/implications
The integrative conceptual framework offers a foundation for future research and SCM practice.
Originality/value
This paper introduces a framework designed to advance the conceptual basis of SCM research and practice with particular reference to the field of public health and disease prevention.
