Abstract
Purpose
This study aims to identify structural breaks in the current account and the periods between these breaks, which the authors name stability spells, and study their characteristics and determinants.
Design/methodology/approach
Using data from the IMF and the World Bank, this study applies the Lee and Strazicich test to endogenously identify breaks and the Heckman selection model to simultaneously study the determinants of structural breaks and current-account changes after breaks.
Findings
This study identifies 212 significant structural breaks and 341 stability spells. These spells become shorter and more volatile the further they are from equilibrium, and half of them last 10 years or less. The results show that economic growth and foreign-exchange piling are particularly useful to prevent breaks, while lower per capita income increases exposure to break risks.
Originality/value
This study introduces the concept of current-account stability spells to refer to the periods between structural breaks. These spells are then studied to determine their main characteristics. The authors also apply a global perspective in their analysis, using a wide sample of 181 economies between 1980 and 2018 and considering positive and negative breaks in both level and trend.

Abstract
This article presents a theoretical investigation of the concept of ‘subject’ or ‘subject matter’ in library and information science. Most conceptions of ‘subject’ in the literature are not explicit but implicit. Various indexing and classification theories, including automatic indexing and citation indexing, have their own more or less implicit concepts of subject. This fact puts the emphasis on making the implicit theories of ‘subject matter’ explicit as the first step. A very close connection exists between what subjects are, and how we are to know them. Those researchers who place the subjects in the minds of the users have a conception of ‘subject’ different to that possessed by those who regard the subject as a fixed property of the documents. The key to the definition of the concept of ‘subject’ lies in the epistemological investigation of how we are going to know what we need to know about documents in order to describe them in a way which facilitates information retrieval. The second step therefore is an analysis of the implicit epistemological conceptions in the major existing conceptions of ‘subject’. The different conceptions of ‘subject’ can therefore be classified into epistemological positions, e.g. ‘subjective idealism’ (or the empiric/positivistic viewpoint), ‘objective idealism’ (the rationalistic viewpoint), ‘pragmatism’ and ‘materialism/ realism’. The third and final step is to propose a new theory of subject matter based on an explicit theory of knowledge. In this article this is done from the point of view of a realistic/materialistic epistemology. From this standpoint the subject of a document is defined as the epistemological potentials of that document.

Abstract
The author’s previous work, itself based on the work of Martin Heidegger and then the Speech Act theorists grounded two important claims. First, computers are about communication, not computation or data processing. Second, communication is primarily about the coordination of commitments to act. This paper argues, as a review of the thinking in Understanding Computers and Cognition, that much is still to be learned about how speech acts work to structure commitments and how the interlinked structure of multiple commitments determines the kind of actions possible in any institution. The paper considers the way the Web establishes sites, virtual communities, and so forth. By referring to Hegel, Kierkegaard, and Heidegger on identity, the paper examines the sorts of identities virtual places are currently making possible and the development that virtual, identity forming practices will need to undergo if virtual sites are to act as real sites do.

Abstract
Purpose
The paper aims to show how resource‐based views of the firm inadequately address the strategic importance of acquiring and using symbolic capital within the wider discursive institutional environment.
Design/methodology/approach
A single case using publicly available data on the strategic activities of the oil and gas firm BP was constructed.
Findings
Combining case data with a review of literature on firm capabilities and organization studies, the paper identifies a previously unacknowledged foundational strategic capability: securing a licence to act. It finds BP strategists understanding this capability as the realization of credibility and authority arising from the conscious and skilled articulation of firm commitments and activities.
Originality/value
Generalising from the case, the paper argues for the importance to firm performance of an understanding of how capabilities evolve in relation to the use of symbolic capital within inherently complex institutional environments. This leads beyond a purely economic view of institutional settings to cover market‐based political and social interests.

Abstract
Purpose
Despite the popularity of the Computational Thinking (CT) paradigm and the call for broad social diffusion of CS fundamentals, the authors argue that the concept is inherently limited and limiting and does not sufficiently convey an understanding of how to enable people to create with computational technologies. The authors suggest an alternate paradigm, procedural creativity, that calls for the development of conceptual creative spaces governed by procedurally generative principles. The authors also call for game development to be the focus of procedural creativity pedagogy.
Design/methodology/approach
The authors first discuss the limitations of the CT paradigm, focusing, in particular, on the issue of abstraction and representation as opposed to execution and action. The authors then define procedural creativity in more detail. Following that, they discuss the use of game development as pedagogy, with a focus on Margaret Boden’s notion of conceptual creative spaces.
Findings
CT is limited because it focuses overly on solutions to computational “problems”, because it is tied too closely with economic concerns and because it focuses on abstraction at the cost of action. Procedural creativity, on the other hand, focuses on the individual’s capacity for personal expression with the computer and on the generative capacity of code in action. Game development is in ideal platform for procedural creativity because it emphasizes the development of creative domains and conceptual spaces.
Originality/value
This paper offers a challenge to the CT status quo and presents a novel way forward for understanding computation as a creative practice.

Abstract
Purpose
The history of cybernetics holds important lessons for how we approach present-day problems in such areas as algorithmic regulation and big data. The purpose of this paper is to position Project Cybersyn as a historical form of algorithmic regulation and use this historical case study as a thought experiment for thinking about ways to improve discussions of algorithmic regulation and big data today.
Design/methodology/approach
The paper draws from the author’s extensive research on Cybersyn’s history to build an argument for how cybernetic history can enrich current discussions on algorithmic regulation and the use of big data for governance.
Findings
The paper identifies five lessons from the Cybersyn history that point to current data challenges and suggests a way forward. These lessons are: first, the state matters; second, older technologies have value; third, privacy protection prevents abuse and preserves human freedom; fourth, algorithmic transparency is important; and finally, thinking in terms of socio-technical systems instead of technology fixes results in better uses of technology.
Research limitations/implications
Project Cybersyn was a computer network built by the socialist government of Salvador Allende under the supervision of the British cybernetician Stafford Beer. It formed part of the government’s program for economic nationalization. Work on the project ended when a military coup brought the Allende government to an early end on September 11, 1973. Since we do not know how the system would have functioned in the long term, parts of the argument are necessarily speculative.
Practical implications
The paper uses Cybersyn’s history to suggest ways that the Chilean experience with cybernetic thinking might enhance, improve, and highlight shortcomings in current discussions of algorithmic regulation.
Originality/value
The paper provides an original argument that connects one of the most ambitious cybernetic projects in history to present day technological challenges in the area of algorithmic regulation.

Abstract
In this paper I discuss how feminist research focusing epistemological issues can be used within computer science (CS). I approach and explore epistemological questions in computer science through a number of themes, which I believe are important to the issues of what knowledge is produced as well as how it is produced and how knowledge is perceived in CS. I discuss for example paradigms and metaphors in computer science, the role of abstractions and the concept of naturalisation. In order to illustrate epistemological views in CS and how these can be questioned from the viewpoints of feminist epistemology, I also do a close reading and commenting of a recent book within the philosophy of computing.

Abstract
Develops the idea of complexity and its implications for our understanding of organisations and society. One such implication is the constitution of autonomous units within autonomous units. This notion is at the core of recursive organisations. Each of these autonomous units requires strengthening in its identity, cohesion and citizenship in order to perform well in its medium. However, in contemporary societies the rule is fragmented institutions rather than whole organisations. Further research is necessary in order to understand how to make more likely the emergence in society of recursive organisations.

Abstract
Purpose
The purpose of this paper is to partially summarize and discuss a lengthy exchange of e‐mails during the summer of 2009 on the issue of uncertainty and associated Chinese complexity studies; with reference also to other fundamental issues including creativity. Some important sources of online information are mentioned, including means of downloading classic texts.
Design/methodology/approach
The aim is to review developments on the internet, especially those of general cybernetic interest.
Findings
The main finding is that the significance of grey system theory is still controversial, though rated highly in certain quarters. Further study is clearly needed.
Practical implications
Eventual resolution of the controversy about approaches to uncertainty will clearly influence further investigation.
Originality/value
It is hoped this is a valuable periodic review.
