After anterior cruciate ligament reconstruction, adjustable braces commonly restrict knee range of motion using rigid flexion stops, which can produce abrupt impacts and discomfort. Passive compliant mechanisms remain hardware-dependent. We developed a software-defined impedance soft stop for powered knee orthoses, implemented as a gain-scheduled proportional-derivative controller that increases stiffness and damping near a prescribed flexion boundary with angle- and velocity-gated engagement. We conducted a counterbalanced six-condition crossover pilot study (physiological gait, orthosis only, orthosis plus motor with the soft stop disabled, rigid stop, firm soft stop, and mild soft stop) with $ n=8 $ healthy adults walking at 3 km/h. Outcomes included knee kinematics from the actuator encoder and optical motion capture, actuator torque and compensatory kinematics, and eight-channel surface electromyography (sEMG). Relative to the motor-only condition, soft stops reduced swing-phase knee flexion ($ {q}_{95} $) from $ {61.1}^{\circ } $ [58.4, 63.8] to $ {37.1}^{\circ } $ [36.4, 37.8] (firm) and $ {44.6}^{\circ } $ [43.4, 45.8] (mild), and reduced flexion velocity from $ 3.63 $ to $ 1.02 $–$ 1.47\;\mathrm{rad}/\mathrm{s} $. Mean resisting torques remained modest ($ 2.64\;\mathrm{N}\;\mathrm{m} $ firm, $ 1.65\;\mathrm{N}\;\mathrm{m} $ mild), and compensatory kinematic changes were generally small. During terminal swing, the analysis identified higher right-biceps-femoris average rectified value with the rigid stop than with both orthosis baselines and both soft-stop conditions. Angle- and velocity-gated impedance soft stops provided effective software-defined flexion limitation in a powered knee orthosis while keeping torque demands low and avoiding increased biceps femoris activation and perceived burden associated with rigid stops. Clinical performance after ACL reconstruction remains to be evaluated.
Comparative trust scholarship has long recognised that ‘ownership’ is an unstable comparator across civilian and common law systems, yet it has not supplied an affirmative replacement independent of any one tradition’s doctrinal vocabulary. This article proposes a three-axis framework — control, administration and benefit — as an alternative unit of comparison. The axes distinguish functional capacities without first deciding who holds ownership or title. The legal vesting of title is then considered separately as part of each system’s doctrinal implementation of that allocation. The framework is applied to the civilian bewind in its South African, Dutch and Belgian forms, to the Quebec and French fiducies and to the common law trust. The bewind is used not as an analogy or a normative model, but as a diagnostic contrast: its allocation of control and administration to the administrator, while locating benefit with the beneficiary, exposes the different combination of legal title, control and administration in the common law trustee. On this account, the trustee’s indemnity-backed lien, priority disputes and related insolvency and third-party liability problems are reconstituted as consequences of a structural allocation rather than as isolated doctrinal anomalies. The article situates structural contrast within the functional tradition and alongside the formants and transplant approaches. Its claim is methodological rather than reformist: structural allocation, not ownership, is the proper unit of comparison.
Raising and control structures in Present-day English are surface-identical, yet differ in crucial ways both syntactically and semantically. We study the difference between the two from a diachronic and acquisitional perspective. Historically, raising has been argued to have emerged out of control (Higgins 1990). Similarly, raising has been found to be developmentally delayed compared to control (e.g. Wexler & Culicover 1987). We use quantitative methods to study the spread of TO-infinitives in child-directed and child naturalistic speech. In parallel, we study the same process in Early Modern English and what distributional properties may have facilitated the emergence of the distinction. Furthermore, we put to the test a learning model, the Tolerance Principle (Yang 2016), against the diachronic data. We argue that the emergence of raising historically was most likely a consequence of the broader rise of the requirement for an overt subject – an argument that has a clear parallel in recent research on the acquisition of raising using the same methods (Irani 2019).
We examine the acceptability of agreeing infinitivals in Brazilian Portuguese (BP) using an offline Bi-modal Acceptability Judgment Task (B-AJT) based on Modesto (2018. Complement clauses in Portuguese: Syntax and acquisition (pp. 59–129). John Benjamins.), originally designed to test the Movement Theory of Control (MTC, e.g., Hornstein 1999. Linguistic Inquiry, 30, 69–96.). Following the MTC, subject raising and subject-control sentences are analyzed uniformly within a formal syntactic paradigm (e.g., Chomsky 1995. The minimalist program. MIT Press. et sequens). Rodrigues and Hornstein (2013. Syntax, 16(3), 292–309.) argue that intuitions on agreeing infinitives in BP in Modesto (2018. Complement clauses in Portuguese: Syntax and acquisition (pp. 59–129). John Benjamins.) are inconclusive and not worthy of serious consideration, thus neutralizing a would-be challenge to the MTC. We examine acceptability data from BP speakers (n = 52) living in the Southeastern US, which reveal a statistically significant difference (p < 0.029) in the acceptability of partial control (PC, m = 1.68/4) and no-control (NC) sentences (m = 2.26/4) with agreeing infinitives. We interpret this to be indicative of robust intuitions related to sentence structures with agreeing infinitives. The validity of such intuition data lends further credence to Merchant and Gupton (2025. Journal of Linguistics, 61(2), 301–337.), which reveals significant processing differences between control and raising structures, which is unexpected under the MTC account. Linear regression results reveal a correlation between geographic region and acceptability, highlighting the importance of geographic variation, which can reveal subtle microparametric differences within languages.
Greek na-clauses are central to the debate on syntactic control, as they have been claimed to involve obligatory control (when selected by a control predicate) despite inflection on the verb. In this paper, we argue that Greek na-clauses also challenge the common assumption that control can only target the subject (rather than other arguments) of the embedded clause, on the basis of tough-constructions, where a non-subject clitic resumes the matrix subject. We show that genuine tough-constructions are best analysed as obligatory control due to both syntactic (mandatory coreference of the clitic, locality of the dependency, presence of the clitic with focus/quantifiers, lack of real reconstruction) and semantic (sensitivity to the features and $ \theta $-role of the DP) constraints. We argue that an Agree-based theory of control (Landau 2015) can capture tough-constructions and other cases of control of clitics in Greek by treating the clitic as a minimal pronoun with unvalued $ \unicode{x03D5} $-features on T – the same projection hosting verbal inflection.
This article assesses the prospective functionality and value of a backward-walking (BW)-specific controller implemented on a swing-assist knee prosthesis prototype, relative to BW functionality offered by conventional daily-use prostheses. The BW control structure is presented and subsequently assessed in an overground experimental protocol involving four individuals with transfemoral amputation, comparing metrics associated with BW when using the dedicated BW controller to walking with daily-use conventional prostheses. Results indicate that the swing-assist BW controller provided significantly greater swing phase knee flexion, higher heel clearance, and reduced hip compensation compared to daily-use devices.
In this work, a space-based shade at the Sun-Earth Lagrange point ${L}_{1}$ is considered as a mitigation strategy to combat climatic warming. It is proposed to utilise solar radiation pressure (SRP) for stabilisation and control of the shade at ${L}_{1}$. Paraboloid shade geometry is proposed with an array of variable-orientation solar panels along the shade’s periphery for control purposes. It is shown that for suitable choices of the shade curvature and material density, all rotational modes as well as translational modes along the directions normal to the Earth-Sun line are inherently stable for this shade. Active control is necessary to achieve stabilisation along the Earth-Sun axis. The challenges associated with the concept and implementation are briefly examined and summarised.
This chapter introduces the reader to transparency and explainable AI. It provides an overview of how to build controls related to transparency and explainable AI.
Japanese society is subject to centrifugal forces that tend to promote diversification in structural arrangements, lifestyles, and value orientations, while a range of centripetal forces drives it towards homogeneity and uniformity. This chapter endeavors to recapitulate these two forces in the context of Japan’s civil society, focusing on five key areas.
The first four investigate various aspects of centrifugal forces: the fragmentation of social relations, a significant development affecting the foundations of Japanese society over the past few decades; the rise of social movements in the 2010s despite this trend; the quiet growth of volunteer activities and the role of NPOs and NGOs as a backdrop for dissenting protests, and the shifting landscape of interest groups overall; and the viability of an emic notion similar to citizenship in analyzing the Japanese context.
The final section aims to establish an analytical framework for various forms of centripetal control and to synthesize their diverse characteristics as ‘friendly authoritarianism’ permeating Japanese society.
Considers what the book covers and what it does not. Provides historiographical context about food cultures among the enslaved, many of which focused on what people ate, whether they were “well-fed” and “Mammies” within domestic spaces. Instead, this book centers everyday routines of food distribution, preparation, and consumption among the enslaved, stressing the vital role played by women who cooked for the quarters within slavery’s wider capitalistic development. Explores Black feminist epistemologies offering alternative methodologies where archival evidence is lacking. Questions dominant modes of feminist thinking. Rather than defining homes and kitchens as prisons, they can be refuges from a racist outside world, a “homeplace.” Examines the duality of cooking as a monotonous chore and an expression of love, and the key concept of “othermothering.” Explains how I utilize the terms “nurses” and “age” and my contribution to methodological discussions of primary sources, including WPA narratives, published autobiographies, travel accounts, enslavers’ records (especially postbellum), and archaeological evidence. Elaborates on regionality and temporality within the research.
This chapter motivates the project of the book by arguing against the decompositional picture of action. It is argued that this picture alienates agents from their own actions, by restricting their role to merely providing goals and plans while delegating execution to sub-personal mechanisms. Through analysis of agential control – the distinctive guidance agents exercise over their intentional actions – the chapter demonstrates that standard approaches fail to capture genuine agent involvement. Special attention is given to contemporary reliability-based accounts of control, as well as to approaches that appeal to knowledge-how. Neither approach, it is argued, suffices to avoid the problems with the decompositional picture. The chapter concludes that an alternative account is needed, where the mind is genuinely embodied in overt action. As part of clearing the ground for the arguments that follow, the chapter provides responses to recent, empirically motivated scepticism about the concept of intentional action, and suggests that agential control is the ‘mark’ of intentional action.
This book develops and defends a novel ‘knowledge-first’ theory of intentional action that places knowledge at its core. The project is motivated by problems with the dominant ‘decompositional picture’ of action. The decompositional view treats actions as composed of two separate components: external bodily movements and internal mental states (intentions, desires, beliefs). Such views, it is argued, fail to accommodate a central feature of intentional action: namely, the fact that intentional actions are characteristically actions that are controlled, or guided, by their agents. As a result, the decompositional picture threatens to radically alienate us from our own bodily actions. Building on ideas from Elizabeth Anscombe, this book argues for a non-decompositional account of intentional action that places a certain kind of knowledge – practical knowledge – at its centre. Along the way, a number of related topics are discussed, such as the nature of agential control, skill, and an ontology of actions as hylomorhically structured particulars.
This chapter develops an account of agential control as a capacity for practical knowledge, departing from traditional decompositional approaches that separate mental planning from bodily execution. Drawing on ideas from George Wilson and Elizabeth Anscombe, among others, the chapter argues that exercising control over action consists in knowingly implementing ways of acting, where such knowledge is practical rather than theoretical. Practical knowledge in the relevant sense is not pre-existing knowledge how to do something that is applied in action, but knowledge of what you are currently doing that is manifested in keeping your ongoing action on track. On the proposed view, agents’ epistemic engagement with their own intentional actions constitutes rather than merely accompanies their exercise of control. This non-reductive, knowledge-first account of agential control is defended against objections arising from the gradability of control and from the possibility of unreflective but skilled action. Accounts of skill and knowledge-how are also sketched.
‘Democratic representation’ seems to have no explanatory power for the current structure and operation of universal IOs and a weak justificatory value for upcoming political reforms of these IOs. However, under the benefit of a renewed approach to universal IOs functions and deliberation, which is one of their meta-functions, the creation of new subsidiary bodies designed to accommodate delegates from Non-State Actors (NSAs) and enable, or even compel, intergovernmental bodies to take into account other interests and perspectives appears to be both necessary and feasible, without any reference to contentious criteria of representativeness based on a fragile principle of democratic legitimacy in IL. The alternative to ‘democratic representation’ consists in amplifying diffuse attempts to redesign the institutional architecture of universal IOs and harnessing the potential of international institutional law, implied powers and privileges and immunities regimes for the sake of a genuinely international, transnational and transgenerational deliberation. Concretely, people speaking for sub-state communities (e.g. from the Global South), future generations or natural entities for instance should be given an institutional role within consultative subsidiary bodies, in combination with state representatives or scientific experts, or not – depending on what is necessary for the fulfilment of the IOs functions. The current context of exacerbated competition between more democratic and less democratic states, some of them obviously being authoritarian, also pleads for a modest approach to IOs political reform leaving the concept of democracy unaltered.
Many contemporary international organizations (IOs) are empowered to adopt international law that claims to bind their Member States (and, directly or indirectly, their peoples). Certain IOs have also become members of other Ios or, at least, active participants in international lawmaking processes that claim to bind those IOs and their Member States (and their peoples).Generally speaking IOs play a central role in contemporary international lawmaking: they institutionalize most of the processes through which international law is adopted today, be it through international conferences, international courts, or as IO secondary law. From the perspective of the democratic legitimacy of international law, this raises the question of the conditions under which those Ios may be regarded as democratic representatives of their Member States’ peoples and, accordingly, under which the international law they have the right or discretion to adopt inside and outside of IO organs and processes may claim to bind those peoples legitimately.
What might entitle agents or agencies that are not sponsored by the state, only by some other social group or organization, to represent their people in an international forum. A state-centred approach would deny that they ever have a title to such a role, while an individual-centred approach would hold that they have as good a title as the state. Both approaches have problems and the paper presents a third, more satisfying alternative. On this approach, such bodies may claim to represent their people insofar as the state enjoys standby control over their proposals, being able to oppose them, should it wish to do so, with a radical veto or a moderate refusal to be bound. Ideally, however, the state with such standby control will be required to allow the proposals to be publicized domestically and to provide reasons for opposing them, if that is what it chooses to do. Under the arrangement proposed, state-independent representatives will be able to explore innovative ideas collaboratively with their counterparts from elsewhere, to identify imaginative solutions to common problems, and to have the opportunity to persuade their own states, under domestic pressure, to fall in line.
This chapter explores William Burroughs’ equivocal position within the American literary canon, examining both the institutional challenges to his inclusion and the theoretical strategies scholars have used to argue for his legitimacy. Sean Bolton traces critical attempts to align Burroughs with modernism, postmodernism, and even a proposed “amodernist” tradition, while also acknowledging the persistent difficulty of assimilating his work into stable frameworks of interpretation. Drawing on Harold Bloom’s aesthetics of canonicity, poststructuralist theory, and his own concept of “narrative revolution,” Bolton contends that Burroughs’ formal innovations – particularly the cut-up method and fragmented subjectivities – both exemplify and exceed existing literary categories. Ultimately, the chapter questions whether Burroughs needs the canon at all, suggesting that his enduring cultural influence may rest precisely on his resistance to assimilation. For readers and scholars alike, Burroughs remains an outsider by design, a figure whose work continues to provoke, disturb, and inspire on its own uncompromising terms.
This chapter traces William Burroughs’ lifelong obsession with disease – particularly cancer and viruses – as a central metaphor in his critique of power, control, and modernity. Polina Mackay and James Mackay argue that Burroughs’ engagement with medicine, from his early syphilis diagnosis to his interest in Wilhelm Reich’s unorthodox theories, shaped his representation of illness as both literal and ideological contagion. From Junky to Naked Lunch, the cut-up texts, and Blade Runner: A Movie, Burroughs portrays medical institutions and bureaucracies not as healing forces but as agents of repression, manipulation, and decay. The chapter shows how Burroughs’ writing fuses Reichian thought, alternative medicine, and paranoid systems theory into a distinctive epidemiology of language, addiction, and social control. While his metaphoric conflation of disease and power reveals the limits of postwar biopolitics, it also risks collapsing critical inquiry into conspiracy. Ultimately, Burroughs’ viral imagination oscillates between incisive cultural diagnosis and reactionary anxiety, offering a vision of medicine as both metaphor and battleground.
Burroughs’ writing is widely interpreted to depict existence in terms of universal addiction, and a fight against it. This chapter shows the extent to which drug use in his life and work lies outside this simplistic model. His ‘Algebra of Need’ polemics are shown to belong to a specific period, and an account of his career with drugs outlines his opiate use; his excursion into hallucinogens, notably yagé, as psychic exploration; and his chosen literary precursors, notably De Quincey. Burroughs became more comfortable with his dependency in later life, and he finally emphasizes drug use, particularly in an American historical context, as a libertarian political issue. The chapter notes his depiction of drug experience as a potentially valuable subjective space, together with nostalgia and dreaming, and suggests that a common denominator throughout his changing stances on drugs is freedom: not only from addiction, but from the body, and from social control.
The foundation of the chapter is the distinction between regulation and control, and the link between them. The distinction is exemplified by the regulation of body temperature by means of control actions;for example, shivering, sweating, and changing the relation with the environment. The latter reflects motivation. The discussion then goes on to document a number of phenomena that also illustrate regulation and control: non-suicidal self-injury, hair pulling, skin picking, addictions of various sorts, and borderline personality disorder.
