Theorists have responded to the challenge of pluralism in East Asia by either advocating a less-demanding form of Confucianism or neutral liberal democratic institutions. This article transcends this dichotomy by extending the challenge down to the individual, prioritizing “exit-based” institutional mechanisms characterized by polycentric interjurisdictional competition over collective “voice.” Drawing from the tradition of epistemic liberalism, this framework not only provides groups the space to enact their moral commitments but facilitates cultural discovery in a complex environment where knowledge of what is of cultural importance is in the first place not centralizable. Our novel proposal accepts the pluralist’s preference for an anti-perfectionist regime without being committed to political democracy. In our approach, not only is Confucianism knocked off its special status in justifying the social order, even democracy is deprived of its special status in the arena of governance.

If you examine the changing contexts in which the issue of ‘relevance’ has been posed in the profession, it becomes clear how earlier calls for relevance need to be reconfigured today. After reviewing arguments that show how explanatory/normative activity is intercoded, this essay explores how the accelerated pace of life, new densities of interdependence and a growing fragility of things supports the case for forging alliances between political science and recent developments in complexity theory in a number of allied fields.

This paper argues that recent struggles against neoliberal axioms such as free trade and open markets have led to a militant reframing of global civil society by grassroots social movements. It contests that this struggle to invest the concept of global civil society with transformative potential rests upon an identifiable praxis, a “strange attractor” that disturbs other civil society actors, through its rearticulation ofa politics that privileges self-organization, direct action, and direct democracy. The paper further suggests that the emergence of this “antagonistic” orientation is best understood through the lens of complexity theory and offers some conceptual tools to begin the process of analyzing global civil society as an outcome and effect of global complexity.

This article presents a computational analysis of the 185 dissimilation patterns in the typological surveys by Suzuki (1998) and Bennett (2013), and shows that dissimilation is computationally less complex than has been previously shown. Dissimilation patterns are grouped into three general types (basic, blocking, and polarity), each of which can be modeled with a subsequential finite-state transducer. This lends support to the claim that phonological patterns are not only regular, but in fact subsequential, which is a more restrictive class of patterns computationally and provides a stronger bound on the types of processes expected in natural language phonology.

If most decision-making processes aimed at solving societal problems have a network-like character, then a key question is how to deal with networks so that they can achieve valuable solutions to societal problems. Managing networks differs considerably from the management advice contained in organisation textbooks, and there is a large and growing literature on how to manage complex processes in networks. After a short discussion of the emergence and characteristics of networks, the article focuses both on strategies to manage processes within networks – here called ‘process management’ – and on attempts to change the characteristics of networks – here called ‘strategies of institutional design’. Finally, we consider the effects of network management and the evaluation of management strategies, and discuss some future research questions.

We compare the complexity of idiosyncratic sound patterns involving American English /ɹ/ with the relative simplicity of clear/dark /l/-allophony patterns found in English and other languages. For /ɹ/, we report an ultrasound-based articulatory study of twenty-seven speakers of American English. Two speakers use only retroflex /ɹ/, sixteen use only bunched /ɹ/, and nine use both /ɹ/ types, with idiosyncratic allophonic distributions. These allophony patterns are covert, because the difference between bunched and retroflex /ɹ/ is not readily perceived by listeners. We compare this typology of /ɹ/-allophony patterns to clear/dark /l/-allophony patterns in seventeen languages. On the basis of the observed patterns, we show that individual-level /ɹ/ allophony and language-level /ɹ/ allophony exhibit similar phonetic grounding, but that /ɹ/-allophony patterns are considerably more complex. The low complexity of language-level /l/-allophony patterns, which are more readily perceived by listeners, is argued to be the result of individual-level contact in the development of sound patterns. More generally, we argue that familiar phonological patterns (which are relatively simple and homogeneous within communities) may arise from individual-level articulatory patterns, which may be complex and speaker-specific, by a process of koineization. We conclude that two classic properties of phonological rules, phonetic naturalness and simplicity, arise from different sources.

In this article, I apply the contributions of Luhmannian systems theory to the analysis of the third sector, accepting, in realistic terms, the diagnosis of current societies as increasingly complex and the descriptions of third sector as hybrid. After identifying some of the main analytical elements and concepts, I propose applying it in two ways. First, with the illustration of organizations’ self-descriptions, I show how third sector organizations may be analyzed in light of the concepts of self-reference, reflexivity, and reflection to evidence both their operational closure and their structural couplings with other systems. Second, I refer to the self-descriptions of “sector” in terms of its self-reflection and semantics as different from other sectors and show that it is a paradoxical heterogeneous unity. I conclude by arguing for the usefulness of this analytical framework to understand contextually the meaning of the third sector in functionally differentiated societies.

Resilience has become a central concept in academic and political debates about government policy over the last decade or so. In a complex, global and interconnected world, resilience appears to be the policy buzzword of choice, assumed to be the answer to wide-ranging range of policy issues. In his book Resilience: The Governance of Complexity, David Chandler takes on the concept of resilience and the ways in which it is used by policymakers and academics. In their discussion of the book, Julian Reid and Philip Hammond critically engages with some of Chandler’s conclusions while approving of other aspects of the book. They query the relationship between the concept of resilience, the concepts of biopolitics and neoliberalism, and the possibility of critique. The debate about resilience thus sits at the heart of contemporary politics, and the debate links concerns of scholars in a number of sub-disciplines within political science.

The verbal suffixes of Seri (a language isolate of Sonora, Mexico) divide the lexicon into classes of unparalleled complexity. The paradigm has only four forms, which mark subject number and aspect (or event number), yet there are over 250 distinct types in a corpus of just under 1,000 verbs. This relation of forms to types means that by information-theoretic measures this is among the most complex inflection class systems yet studied. In part this complexity is due to the sheer wealth of allomorphs and the freedom with which they combine within the paradigm; however, these properties can be found in all inflection class systems of any complexity. The unique property of Seri is that although the suffix morphology and the morphosyntactic paradigm have the same featural content, the two systems are not directly coordinated. Both suffix morphology and verbal morphosyntax are based on the concatenation of markers of plurality, and an increase in the morphological marking of plurality reflects a morphosyntactic accumulation of subject and predicate plurality (i.e. aspect). In this sense, morphology is a direct exponent of featural content. But there is no consistent mapping between the two systems, and the precise calibration between morphological form and morphosyntactic function must be lexically specified; it is this specification that increases dramatically the number of inflectional types. Seri therefore represents a middle ground between the conceptual extremes of morphosyntactically motivated and morphologically autonomous morphology that serve as a basis for much of our theory building.

In this editorial we set out the background to the advent and development of the concept of recovery in mental health care. We follow this with an overview of policy with specific reference to our own locale here in Wales where a recovery-focus is now written into national mental health legislation and policy directions. We briefly summarise our own research in this area and note positive relationships between recovery and social support and quality of life but also limited shared understanding of what recovery might mean alongside gaps in policy aspirations and everyday experiences of using services. The concept of recovery remains contested with concerns it has become a means for neoliberal thinking in services and in effect has been colonised by competing ideas. Despite this (sometimes) conflicting evidence and the polyvalent quality of the concept, recovery retains a sense of vitality and validity as evidenced by contributions to this special issue of the journal. Building on our reading of this growing literature we suggest that recovery necessitates social change, implies an understanding of systems and awareness of complexity and finally must account for and accommodate competing understandings. To achieve its foundational aims, it is imperative that research in this field directly engages and includes people with experience of using mental health services as co-researchers in generating new recovery-focused interventions to address the challenges of severe mental illness experiences.

This article revisits the methodological foundations of Elinor Ostrom’s institutionalism by examining the role of ‘complexity’ in her work and the conceptual influence of Herbert A. Simon. While Simon was not Ostrom’s most frequently cited reference, his thought – particularly as articulated in The Sciences of the Artificial – exerted a formative and enduring influence on her analytical framework. Drawing on Ostrom’s later writings, in which she offers a retrospective account of her intellectual trajectory, we show how Simon’s systems-engineering perspective provides a coherent framework for understanding her approach to institutional complexity, despite notable differences in their respective research objects and theoretical priorities. For Ostrom, institutions evolve incrementally as ‘boundedly’ rational individuals attempt to resolve collective problems through successive modifications of rule structures within complex social systems. In contrast to top-down optimisation models, her work emphasises adaptive responses and practical problem-solving. Interpreting Ostrom’s methodology through a Simonian lens not only deepens our understanding of her contribution to institutional economics but also illustrates the value of interdisciplinary approaches informed by complexity theory for the field.

We study the complexity of deterministic and probabilistic inversions of partial computable functions on the reals.

A recursive set of formulas of first-order logic with finitely many predicate letters, including “=”, has a model over the integers in which the predicates are Boolean combinations of recursively enumerable sets, if it has an infinite model at all. The proof corrects a fallacious argument published by Hensel and Putnam in 1969.

Model-based Systems Engineering (MBSE) supports managing complex engineering projects. A pivotal element of MBSE is the concept of views which provide tailored representations of a system model to address stakeholder concerns. Despite standards describing the use and generation of views, the adoption and practical implementation of MBSE views and viewpoints in industrial practice remain insufficiently explored. Interviews with German practitioners reveal a disconnect between theory and practice: views and viewpoints and the involvement in MBSE are often limited to technical experts, excluding non-technical stakeholders. High complexity, abstract representations, and tool-related barriers impede broader engagement. The findings suggest stakeholder-specific, accessible visualizations integrated into easy-to-use tools to improve understanding, collaboration, and decision-making.
