Abstract
Purpose
The scientific criterion of determinability (predictability) can be framed in realist or in constructivist terms. This can pose a challenge to design researchers who operate between scientific research (which favors a realist view of determinism/indeterminism) and design practice (which favors a constructivist view of determinability/indeterminability). This paper aims to develop a framework to navigate this challenge.
Design/methodology/approach
A critical approach to “scientific” design research is developed by examining the notion of (in)determinism, with particular attention to the observer-based projection of systemic boundaries, and the constructivist understanding of how such boundaries are constituted. This is illustrated using automata theory. A decision-making framework is then developed based on a diagram known as the epistemological triangle.
Findings
The navigation between determinism as a property of the observed, and determinability as a property of the observer follows the navigation between realist and constructivist perspectives, and thus has a bearing on the navigation of the kinds of design research distinguished by Frayling, and their implied primary evaluation criteria.
Research limitations/implications
The presented argument advocates a constructivist view, which, however, is not meant to imply a rejection of, but rather, an additional degree of freedom extending the realist view.
Originality/value
This discussion contributes to the establishment of observational determinability as observer-dependent. The proposed framework connects the navigation between deterministic observables and determining observers to the navigation between the design criteria form, meaning and utility. This may be of value within and beyond design research.

Abstract
Purpose
To trace a shift in attitudes towards control since the mid-twentieth century, as reflected in a shift in rhetoric that accompanied the extension from first- to second-order cybernetics.
Design/methodology/approach
Narratives of exploration that have emerged from NASA’s lunar programme and recent design cybernetics are juxtaposed to show a transition away from the legitimisation of goal-oriented decision-making and control towards advocacy of partial control avoidance and accommodation of the unanticipated.
Findings
Contemporary cybernetic theory recognises the importance of both the partial presence and the partial absence of control in creative epistemic practice. It is thus unsurprising that, according to historical records, NASA’s journey to the moon was enabled not only by the assurance of control but also by lapses of control. However, NASA’s rhetorical posture during the race to the moon focused on predictable control and goal orientation, differing notably from the recent design-cybernetic openness towards uncertainty, error, and serendipity. This difference is encapsulated by the “Failure is not an option” dictum that was associated with NASA’s lunar programme and the “Try Again. Fail Again. Fail Better” equivalent associated with design cybernetics. Recognition of the more recent cybernetic perspective is impeded by its continuing omission from narratives of earlier cybernetic accomplishments.
Research limitations/implications
To the extent that narratives examined in this paper refer to exceptional initiatives and spontaneous events, the repeatability and generalisability of the presented argument are limited.
Originality/value
The paper highlights changing cybernetic narratives of creative invention by examining how spontaneous changes in variety were reported to have been addressed in NASA’s lunar programme, and how recent cybernetic design theory suggests they should be addressed.

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
This paper aims to present the argument that Heinz von Foerster's portrayals of non-triviality in his non-trivial machine (NTM) and in surprising human behavior are not isomorphous. It also demonstrates that the NTM does not account for spontaneity as it is observed in humans in general, nor for von Foerster's own invention of the NTM in particular.
Design/methodology/approach
Demonstrating an isomorphism between the NTM and the Enigma cipher machine, the paper shows differences between the NTM and non-trivial human behavior, which von Foerster implied to be isomorphous. It speculates why von Foerster may have accepted this inconsistency.
Findings
von Foerster's NTM and the Enigma cipher machine are shown to be isomorphous. Multiple portrayals von Foerster offered of non-triviality, however, are neither isomorphous, nor do they satisfy criteria von Foerster himself set for theories of living beings. Speculations are offered as to why von Foerster nonetheless used these portrayals of non-triviality, and regarding a possible lineage of inspiration that connects the Enigma machine to the NTM via the work of Alan Turing and Ross Ashby.
Research limitations/implications
The presented research is informal and speculative.
Originality/value
The paper's originality and value arise from its questioning of the apparent isomorphism of multiple portrayals of non-triviality, from its speculation about choices von Foerster made while facing the dilemma of defending spontaneity in terms of mechanisms, as well as from speculation about his sources of inspiration.

Abstract
Project SSG‐FI at the Lower Saxony State and University Library, Göttingen (Germany) provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. There are now subject gateways for three subject areas: earth sciences (Geo‐guide); mathematics (Mathguide); and Anglo‐American culture (split into History guide and Anglistik guide). Together they receive about 3,300 “hard” requests per day, thus reaching over 1 million requests per year. The project SSG‐FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG‐FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records.

Abstract
In terms of continuum mechanics a twin is represented by the sudden appearance of a shear eigenstrain state in a distinct region. The corresponding elastic strain energy, the interface energy and the energy dissipated due to the irreversible character of the deformation process are investigated. If the total amount of these energy terms, spent by the twinning process, can be provided by the interaction energy of an external and/or internal stress state with respect to the twin shear eigenstrain, then either a deformation twin band or a twin nucleus may appear. Realistic estimations of the dimensions of deformation twins can be presented. This energetic interpretation of twinning is experimentally demonstrated for intermetallic TiAl.

Abstract
Purpose
Existing brand literature on assemblage practices has focused on providing a map or geography of brand assemblages, suggesting that an artist brand’s ability to evolve and achieve brand longevity remains constant. Using geology of assemblage, this study aims to explore the types and mechanisms of change in brand evolutions to address the problem of identifying when and how a brand can transform in an evolving marketplace.
Design/methodology/approach
The authors apply an interpretive process data approach using secondary archival data and in-depth interviews with 31 self-identified fans to explore the artist brand David Bowie over his 50-year career.
Findings
As an artist brand, Bowie’s ability to evolve his brand was constrained by his assemblage. Despite efforts to defy ageing and retain a youth audience appeal, both the media and his fans interpreted and judged Bowie’s current efforts from a historical perspective and continuously reevaluated his brand limiting his ability to change to remain relevant.
Practical implications
Brand managers, particularly artist brands and human brands, may find that their ability to change is constrained by meanings in past strata over time. Withdrawal from the marketplace and the use of silence as a communicative practice enabling brand transformations.
Originality/value
The geology of assemblage perspective offers a more nuanced understanding of brand changes over time beyond the possibilities of incremental or disruptive change. We identify the mechanisms of change that result in minor sedimentation, moderate cracks and major ruptures in a brand’s evolution.

Abstract
Purpose
The purpose of this paper is to present the result of an experiment examining the effects of changing input and output channel variety in an optical feedback system and their potential to give rise to novelty, as some non-trivial systems do.
Design/methodology/approach
The experimental design is based on a digital computer connected to a digital photo camera (input channel), and to a monitor screen (output channel). The camera is pointed at the monitor to form a circular feedback system. Monitor and camera resolutions constitute the variable input and output variety of the system, allowing the visual investigation of effects of variety reduction and variety amplification in circular feedback systems.
Findings
Results suggest that variety amplification in input and/or output channels promotes the emergence of discernible novelty in the apparent absence of a creative/generative capability or agenda within the recursive system.
Research limitations/implications
An analogy between an optical feedback system and human novelty generation is shown, while generalisability of observations made beyond the described experiment remains to be established.
Originality/value
A new approach to the computational modelling of aspects of human creativity is presented. Photographic investigation of variety reduction and variety amplification is new, and hoped to be of value to those wishing to examine these theoretical concepts in concrete terms.

Abstract
Purpose
Circular causality is one of several unorthodox assumptions underlying cybernetics. This paper identifies “blind spots” which obscure the soundness of this assumption, rendering cybernetics liable to rejection. The purpose of this paper is to aid students of cybernetics in appreciating circular causality.
Design/methodology/approach
The presented argument is based on textual and diagrammatic explication of several more or less obvious causal scenarios. Some of these modes are shown to obscure circular causality from observation.
Findings
Previously discussed “blind spots” obscuring circular causality are referenced. The notion of probabilistic causality is developed from the notion of collateral effects, which is introduced by extension of the notion of contributory causality. The possible “lossiness” of probabilistic causation is shown to constitute another “blind spot” obscuring circular causality, for example in design.
Research limitations/implications
The presented argument aims to promote acceptance of circular causality. Assuming a radical-constructivist perspective, it discusses the construction of mental models of causal relationships.
Originality/value
Ignorance of circular causality has previously been attributed to preferences for description in terms of energy, and in terms of timeless logic. Additionally, this paper proposes the obscuring effect of probabilistic causality, and the possible co-occurrence of multiple “blind spots.”
