Abstract
Purpose
The purpose of the paper is to contribute to further advancing of IMP as a research field by setting up and starting a theoretical conversation between system theory and the IMP.
Design/methodology/approach
The approach is based on a narrative literature study and conceptual research.
Findings
The authors find that system theory and cybernetics can be regarded as important sources of inspiration for early IMP research. The authors identify three specific theoretical “puzzles” in system theory that may serve as useful topics for discussion between system theorists and IMP researchers.
Originality/value
Only a handful of papers have touched upon the relationship between system theory and IMP before. This paper combines a narrative, historical analysis of this relationship with developing specific suggestions for using system theory as a vehicle for further advancement of IMP research.

Abstract
Purpose
A growing body of literature focuses on crime hotspots; however, less is known about the spatial distribution of crime at mass transit systems, and even less is known about trajectory patterns of hotspots in non-English-speaking countries.
Design/methodology/approach
The spatiotemporal behaviour of 1,494 crimes reported to the Hong Kong’s Railway Police District across a two-year period was examined in this study. Crime harm weights were then applied to offences to estimate the distribution of crime severity across the transit system. Descriptive statistics are used to understand the temporal and spatial trends, and k-means longitudinal clustering are used to examine the developmental trajectories of crime in train stations over time.
Findings
Analyses suggest that 15.2% and 8.8% of stations accounted for 50% of all counted crime and crime harm scores, respectively, indicating the predictability of crime and harm to occur at certain stations but not others. Offending persists consistently, with low, moderate and high counts and harm stations remaining the same over time.
Research limitations/implications
These findings suggest that more localised crime control initiatives are required to target crime effectively.
Originality/value
This is one of the only studies focusing on hotspots and harmspots in the mass transit system.

Abstract
Purpose
W. Ross Ashby’s elementary non-trivial machine, known in the cybernetic literature as the “Ashby Box,” has been described as the prototypical example of a black box system. As far as it can be ascertained from Ashby’s journal, the intended purpose of this device may have been to exemplify the environment where an “artificial brain” may operate. This paper describes the construction of an elementary observer/controller for the class of systems exemplified by the Ashby Box – variable structure black box systems with parallel input.
Design/methodology/approach
Starting from a formalization of the second-order assumptions implicit in the design of the Ashby Box, the observer/controller system is synthesized from the ground up, in a strictly system-theoretic setting, without recourse to disciplinary metaphors or current theories of learning and cognition, based mainly on guidance from Heinz von Foerster’s theory of self-organizing systems and W. Ross Ashby’s own insights into adaptive systems.
Findings
Achieving and maintaining control of the Ashby Box requires a non-trivial observer system able to use the results of its interactions with the non-trivial machine to autonomously construct, deconstruct and reconstruct its own function. The algorithm and the dynamical model of the Ashby Box observer developed in this paper define the basic specifications of a general purpose, unsupervised learning architecture able to accomplish this task.
Originality/value
The problem exemplified by the Ashby Box is fundamental and goes to the roots of cybernetic theory; second-order cybernetics offers an adequate foundation for the mathematical modeling of this problem.

Abstract
Purpose
Technology‐based new ventures (TNVs) – which rely on entrepreneurial activities based on science and technology applications in newly created organizations to be successful – are important to current economic growth and innovation. Past research has looked at the importance of networks and social capital to TNV performance. Yet these studies rarely provide theoretical predictions of the attributes of network ties. This paper aims to bring TNV theory up to date with respect to twenty‐first century adaptation and complexity conditions.
Design/methodology/approach
The paper draws on new developments in complexity science (specifically scalability and scale‐free theories) and long‐standing first principles of efficacious adaptation to develop TNV‐relevant theory offering an alternative perspective on the impact of network ties on the performance of TNV.
Findings
It is argued that TNVs can achieve superior performance by developing and building moderate numbers of short‐term (and thereby weak) network ties. The theorizing calls for a new research agenda pertaining to TNVs, which are delineated. The paper also develops four propositions as part of setting forth an agenda for future research.
Originality/value
The paper updates the entrepreneurship and social network literatures by reshaping them with respect to the nonlinear order‐creation dynamics of complexity theory and scale‐free dynamics of econophysics. It focuses on the aspects of network theory that are especially likely to set in motion the complex adaptive systems dynamics essential to TNV performance. Therefore, the conceptual framework contributes to TNVs as a guide to achieving higher performance, effectiveness, and longevity in a rapidly changing world.

Abstract
Purpose
The viable system model (VSM) provides a way to understand communication structures in an organization. It gives us a means to visualize and analyze information channels relating the functions in an enterprise, a corporation, or any other kind of organization. At the heart of the VSM is the application of Ashby's law of requisite variety. The resulting models help to analyze and discuss what variety attenuation of operations and what variety amplification of management can establish requisite variety. Many studies and applications show that the complexity management laws described by Ashby and Beer hold, and that managerial, operational and environmental varieties tend to equate. The amplifiers and attenuators, however, should be designed to do so with minimum damage to people and to cost. The purpose of this paper is to determine to what extent the design of amplifiers and attenuators is possible if these are realized based on linguistic communication, and whether this design can be automated in these cases.
Design/methodology/approach
The paper uses logical presentation of ideas along with examples from cases. The basic argument is that the design of information channels – amplifiers and attenuators – relies on self‐organizing processes that depend on an operation called linguistic predication.
Findings
The paper demonstrates that linguistic predication is not computable based on the model of the Turing machine so that this operation is restricted to be carried out by human agents. In these cases, technology is limited to providing a technical means for communication and social processes.
Originality/value
While there is a large knowledge base of literature in the field of applications of the VSM there is less work providing concepts and guidelines for designing information channels. This paper offers a conceptual and logical argument for their characteristics based on linguistics and philosophy of language.

Abstract
Purpose
Ranulph Glanville has argued that ambitions of strict control are misplaced in epistemic processes such as learning and designing. Among other reasons, he has presented quantitative arguments for this ethical position. As a part of these arguments, Glanville claimed that strict control even of modest systems transcends the computational limits of our planet. The purpose of this paper is to review the related discourse and to examine the soundness of this claim.
Design/methodology/approach
Related literature is reviewed and pertinent lines of reasoning are illustrated and critically examined using examples and straightforward language.
Findings
The claim that even modest epistemic processes transcend the computational means of our planet is challenged. The recommendation to assume out-of-control postures in epistemic processes, however, is maintained on ethical rather than on quantitative grounds.
Research limitations/implications
The presented reasoning is limited in as far as it is ultimately based on an ethical standpoint.
Originality/value
This paper summarizes an important cybernetic discourse and dispels the notion therein that epistemic processes necessarily involve computational demands of astronomical proportions. Furthermore, this paper presents a rare discussion of Glanville’s Corollary of Ashby’s Law of Requisite Variety.

Abstract
Purpose
The purpose of this paper is to develop and test theory regarding a geographic halo effect, whereby foreign investors draw overly broad impressions about a country based on high levels of violent crime in specific locations impacting foreign direct investment (FDI) across the country.
Design/methodology/approach
The authors analyze the impact of homicides on FDI by source country into Mexican states from 2001 to 2015. They estimate fixed effect and dynamic panel models controlling for several determinants of FDI at the state level and the potential geographic spillover of such violence from adjacent states.
Findings
The authors find robust support for the existence of a geographic halo effect caused by violent crime. The results show that the highest number of state homicides is associated with lower FDI across states.
Research limitations/implications
The research provides some evidence of the potential role of cognitive biases on FDI decisions. In addition, its focus on Latin America brings attention to an understudied region in international business research.
Practical implications
For practitioners engaged in FDI decisions, the results imply the need to be more aware of potential cognitive biases that may influence them.
Originality/value
Few papers have explored the influence of cognitive biases on FDI.

Abstract
The effect of tolyltriazole (TTA) on the corrosion of Al‐Cu, Al‐Si‐Cu and Al‐Cu‐Fe alloys in HCl (pH = 0.5) and NaCl (pH = 6 and 11) respectively at 15○C, 25○C and 35○C has been studied by electrochemical methods. Corrosion potentials, corrosion rates, polarization resistances, inhibition efficiencies and activation energies have been determined. The results have shown that the inhibition efficiencies of TTA changed with pH and temperature. TTA has been adsorbed on the alloys to form Cu(I)‐TTA film. TTA was more efficient at pH = 0.5 and 6 than at pH = 11. Increasing the temperature from 15○C to 35○C decreased the inhibition effect of TTA.

Abstract
Purpose
Flexibility continues to be key to the competitiveness of manufacturing firms. However, both in academia and industry, there still exists a lack of understanding regarding the fundamental nature of flexibility. This lack of understanding has often led to overly optimistic expectations regarding the direct transformation of technological flexibility into manufacturing flexibility. A theoretical model of the firm, based on cybernetics, is proposed in this paper.
Design/methodology/approach
The model relates flexibility to the cybernetic concept of variety and examines a dynamic system in terms of its task structure.
Findings
The model proves useful both in dispelling some of the misconceptions regarding flexibility, and in providing practical insights into issues of designing flexible manufacturing organizations.
Practical implications
The paper presents a means by which variety can be measured.
Originality/value
The conceptual model clarifies certain aspects of system flexibility. The first implication is that the flexibility required at a node is not fixed, but dependent on its connection with other nodes. The degree to which the interconnected nodes are effective regulators determines the variety impinging upon the target node. The second implication is that variety reduction is often a preferred solution over increased variety handling. The third implication is that the seemingly peculiar finding that relatively inflexible nodes in combination can be quite flexible, is easily explained using this theoretical model of the firm. System flexibility depends more on each node possessing requisite variety than on each possessing an enormous number of responses.

Abstract
Present‐day economics is characterised by the fragmentary and reductionist approach that typifies most social sciences. Economists generally fail to recognise that the economy is merely one aspect of a whole ecological and social fabric; a living system composed of human beings in continual interaction with one another and with their natural resources, most of which are, in turn, living organisms. The basic error of the social sciences is to divide this fabric in fragments, assumed to be independent and to be dealt with in separate academic departments (Capra, 1982, pp. 194–5).
