Widespread reliance on representationalist understandings commit social scientists to either partially or totally decouple belief from reality, limiting the domain of phenomena that can be treated by belief as an analytic concept. Developing the contrastive notion of practical belief, we introduce the hysteresis effect as a situational phenomenon involving the systematic production of agent-environment mismatches and argue for its placement as a central problem for the theory of action. Revealing the dynamic, embodied conservation of belief in the temporality of (...) practice, hysteresis appears when environmental contexts change in a way that leaves actors without an ontologically complicit relationship to institutions as scaffolds of action. Under these circumstances, a past-inflected reflexiveness replaces a forward-inflecting practical belief in the actor's temporal relation to the world. Drawing from a variety of historical case studies, we locate hysteresis in routine disjunctures between the temporality of practice and the temporality of environments. Our analysis reveals four distinct types of reflexiveness produced the hysteresis effect, each with a unique dispositional impact on actors and extensions to group-level phenomena. We conclude the article by emphasizing the non-eliminativist relationship between belief as disposition and belief as representation. (shrink)

This paper explores the implications of some experimental data for views that identify colors with objective physical properties such as reflectance profiles. Those who reject objectivist views often argue from the existence of intersubjective differences in color categorization ; but objectivists have managed to stand their ground by identifying colors with sets or ranges of reflectances individuated by the ways in which they stimulate the visual system. In the interest of moving the debate forward, I provide a new kind of (...) evidence against objectivism. Results of a psycholinguistic experiment reveal hysteresis and enhanced contrast in ordinary speakers’ applications of vague terms. These dynamical patterns are purely psychological and give rise to intra-subjective variation in subjects’ applications of vague predicates; in particular, in the case of color predicates, nothing in the stimulus configuration or the illuminant undergoes any change, the only variable being the order in which stimuli are judged. I hypothesize that these order effects are necessary if vague words are to be applicable to values on dimensions, like color, that admit of continuous change. To the extent that this hypothesis is correct, it suggests that if colors are the properties named by ordinary color predicates, and ordinary color predicates are vague, and the application of vague predicates exhibits the order effects found in the experiment, colours cannot be physical or otherwise objective in nature.

Economies making a transition from centrally planned socialism to market capitalism can experience chaotic hysteresis. This can arise from elements of the previous system persisting even as institutions are transformed with the system possibly experiencing chaos during this conflict. A model of investment cycles accompanied by technological stagnation shows this phenomenon which can be viewed from a cusp catastrophe perspective. Empirical tests of Soviet investment and construction data provide incomplete support for the cusp structure with chaos. Nonlinear structures are (...) found with bifurcation effects for all cases and possibly chaotic dynamics for five-year lagged construction data. (shrink)

I enter a debate about state-socialism elite’s reproduction and higher education to propose an implementation of Bourdieu’s hysteresis effect. I argue that the intelligentsia and the interwar university shaped biographical paths of academics stronger than the political factors, which are usually brought to the forefront by contemporary researchers. I analyse academic biographies shaped by the socialist university and reconstruct a model academic biography in the post-WWII period, in particular, in Poland. I compare it with biographies of professors from working-class (...) and peasant backgrounds, and arrive at the conclusion that the differences are minor. Those who formed a seemingly perfect new intelligentsia were socialized by the traditional academic habitus. A few who entered the new academic world from working class or peasant backgrounds had to embrace the interwar university ethos in order to justify their own merits in belonging. I propose a model of opposite hysteresis vectors to explain tensions between academia and political field. (shrink)

Perhaps the most relevant aspect of the ongoing philosophical transformation is the splitting of binomial speculation-idealism. Indeed, one can be both realist and speculative. The paper aims to show it through a definition of negative, positive, and speculative Realism and emphasises the speculative concept of hysteresis, i.e. the survival of effects to their own causes. Indeed, it is the fundamental principle at the basis of what exists (ontology), what we do (technology), what we know (epistemology), and finally of teleology (...) (that is, of the interruption which, by putting an end to a process, simultaneously assigns a purpose to it). (shrink)

For some decades now, a transformation has been underway that is no less dramatic than the Industrial Revolution, and that just like the latter requires time to be conceptualized. When one seeks to capture the essence of an unprecedented phenomenon, one always uses several, partial, esoteric names: virtuality, Collective Intelligence, Internet, web, big data, artificial intelligence, game… In short, we are all unwittingly drafting a new Visnusahasranāma: a collective poem made up of books, essays, articles, debates, and posts that sings (...) about the thousand names of our Visnu, whose essence however remains unknown. Trying to find a name for this hidden god, I will start from an examination of the current revolution, trying to grasp its specificity, and consequently also its essential differences from the Industrial Revolution; secondly, I will focus on the metaphysical revelation made possible by this revolution (which, like any revolution, does not really transform the world, but rather manifests essential structures that were already present in it, in a hidden or only hinted form); finally, I will devote myself to speculation as to the decisions we must take with respect to the future and the political goals to be pursued with respect to this new world we are living in.

This article describes new aspects of hysteresis dynamics which have been uncovered through computer experiments. There are several motivations to be interested in fast-slow dynamics. For instance, many physiological or biological systems display different time scales. The bursting oscillations which can be observed in neurons, β-cells of the pancreas and population dynamics are essentially studied via bifurcation theory and analysis of fast-slow systems (Keener and Sneyd, 1998; Rinzel, 1987). Hysteresis is a possible mechanism to generate bursting oscillations. A (...) first part of this article presents the computer techniques (the dotted-phase portrait, the bifurcation of the fast dynamics and the wave form) we have used to represent several patterns specific to hysteresis dynamics. This framework yields a natural generalization to the notion of bursting oscillations where, for instance, the active phase is chaotic and alternates with a quiescent phase. In a second part of the article, we emphasize the evolution to chaos which is often associated with bursting oscillations on the specific example of the Hindmarsh–Rose system. This evolution to chaos has already been studied with classical tools of dynamical systems but we give here numerical evidence on hysteresis dynamics and on some aspects of the wave form. The analytical proofs will be given elsewhere. (shrink)

Shape memory alloy- based actuators are widely applied in the compliant actuating systems. However, the measured data of the SMA-based compliant actuating system reveal the input-output hysteresis behavior, and the actuating precision of the compliant actuating system could be degraded by such hysteresis nonlinearities. To characterize such nonlinearities in the SMA-based compliant actuator precisely, a Jiles-Atherton model is adopted in this paper, and a modified particle swarm optimization algorithm is proposed to identify the parameters in the Jiles-Atherton model, (...) which is a combination of several differential nonlinear equations. Compared with the basic PSO identification algorithm, the designed MPSO algorithm can reduce the local optimum problem so that the Jiles-Atherton model with the identified parameters can show good agreements with the measured experimental data. The good capture ability of the proposed identification algorithm is also examined through the comparisons with Jiles-Atherton model using the basic PSO identification algorithm. (shrink)

Hysteresis means literally “that which comes later,” being derived from the Greek verb ύστερέω. Thus, hysteresis effects, generally defined, are those that persist after the initial causes giving rise to the effects are removed. During the course of the 1980s, it became increasingly fashionable to invoke hysteresis effects to explain economic phenomena. Two of the main areas of application were to unemployment and international trade. In the case of unemployment, distinctive features of labor markets, such as social (...) norms that rule out wage-cutting in the face of rising unemployment, imply that “increases in unemployment have a direct impact on the ‘natural’ rate of unemployment”. The implication for macroeconomic systems is that “temporary shocks can have a permanent effect on the level of employment”. In the case of international trade, hysteresis effects arise from the industrial economics of sunk costs: “the argument is that firms must incur sunk costs to enter new markets, and cannot recoup these costs if they exit.… thus foreign firms that entered the U.S. market when the dollar was high do not abandon their sunk cost investments when the dollar falls.” The implication for trade flows is “an effect which persists after the cause that brought it about has been removed”.

In the present study, we have demonstrated hysteresis phenomena in the excitability of single, enzymatically dissociated guinea pig ventricular myocytes. Membrane potentials were recorded with patch pipettes in the whole-cell current clamp configuration. Repetitive stimulation with depolarizing current pulses of constant cycle length and duration but varying strength led to predictable excitation (1:l) and non-excitation (1:0) patterns depending on current strength. In addition, transition between patterns depended on the direction of current intensity change and stable hysteresis loops were (...) obtained in stimulus:response pattern vs. current intensity plots in 14 cells. Increase of pulse duration and decrease of stimulation rate contributed to a reduction in hysteresis loop areas. Changes in amplitude and shape of the subthreshold responses during the transitions from one stable pattern to the other, suggested that activity led to an increase in membrane resistance, particularly in the voltage domain between resting potential, and threshold. Therefore, we modelled the dynamic behaviour of the single cells as a function of diastolic membrane resistance, using previously published analytical solutions. Numerical iteration of the analytical model equations closely reproduced the experimental hysteresis loops in both qualitative and quantitative ways. In particular, the effect of stimulation frequency on the model was similar to the experimental findings. The overall study suggests that the excitability pattern of guinea pig ventricular myocytes accounts for hysteresis and bistabilities when current intensity is allowed to fluctuate around threshold levels.

Sociological theory on the phenomenon of suicide continues to rely heavily upon the Durkheimian perspective. While such accounts are valuable additions to the field, engagement with alternative theoretical traditions may likewise be stimulating and provide distinct concepts to delve into the issue. This article contributes to expanding sociological understanding of suicide by drawing upon Pierre Bourdieu’s theory, a relatively untapped resource in the study of suicide. I suggest that the concept of hysteresis – a mismatch between embodied and objectified (...) structures – enables an understanding of under what circumstances agents may become vulnerable to suicide. I then theorise how socioeconomic, political, and cultural dynamics may deepen the hysteresis effect and increase the chances that individuals in specific social positions experience it. Finally, I argue that individuals’ responses to such distress depend on their space of possibles: the culturally laden idea of suicide and alternatives to it. (shrink)

This paper proposes an experimental investigation of the use of vague predicates in dynamic sorites. We present the results of two studies in which subjects had to categorize colored squares at the borderline between two color categories (Green vs. Blue, Yellow vs. Orange). Our main aim was to probe for hysteresis in the ordered transitions between the respective colors, namely for the longer persistence of the initial category. Our main finding is a reverse phenomenon of enhanced contrast (i.e. negative (...) hysteresis), present in two different tasks, a comparative task involving two color names, and a yes/no task involving a single color name, but not found in a corresponding color matching task. We propose an optimality-theoretic explanation of this effect in terms of the strict-tolerant framework of Cobreros et al. (J Philos Log 1–39, 2012), in which borderline cases are characterized in a dual manner in terms of overlap between tolerant extensions, and underlap between strict extensions. (shrink)

I present a novel argument against the epistemic conception of perception according to which perception either is a form of knowledge or puts the subject in a position to gain knowledge about what is perceived. ECP closes the gap between a perceptual experience that veridically presents a given state of affairs and an experience capable of yielding the knowledge that the state of affairs obtains. Against ECP, I describe a particular case of perceptual experience in which the following triad of (...) claims is true: The experience presents a given state of affairs ; The experience is veridical; The experience cannot yield the knowledge that the state of affairs obtains. This case involves an empirically well-studied phenomenon, namely perceptual hysteresis, which involves the maintenance of a perceptual experience with a relatively stable content over progressively degrading sensory stimulations.

In this ethnography of Full Contact, a San Francisco Bay Area boxing gym, I use Bourdieu’s theory of practice to illustrate how ‘rules of the game’ shape people’s perceptions, interactions and positions (capital). First, I show how the unwritten, unspoken rules of boxing as a field (its doxa) impact readings of bodies and bodily capital, readings that then have an impact on micro-level interactions and hierarchies at Full Contact. Second, I show the micro-level consequences of hysteresis – delays in (...) the realignment of habitus and field that result from change at the field level – on social interactions and hierarchies. Gender is at the core of my analysis, for it is both a fundamental part of my and others’ habitus, and a symbolic trait of significance in the hypermasculine doxa of boxing as a field. (shrink)

La catégorie du suranné, appliquée à l’objet esthétique, notamment au produit de l’activité artistique, désigne une mesure, un kairos, qui se situe entre l’ancien qui ne s’érige pas encore en classique et le contemporain qui n’est pas encore jugé démodé. Il qualifie tout objet esthétique en passe d’acquérir une valeur d’ancienneté sans pour autant s’affirmer comme universellement acceptable et sans s’imposer impérativement. Il ne détermine ni ce qui a vieilli ni ce que l’on qualifierait de vieillot; il dénote, plus particulièrement, (...) un état intermédiaire, plus ou moins officiellement reconnu, qu’il relie au présent. Dans cet ordre d’idées, le suranné implique pour la conscience esthétique un jeu dialectique entre ce qui est directement vécu et ce qui est poursuivi, avec, en plus, un rien de dédain, mais aussi avec un certain regret à son égard. Il équivaut à un présent rétentionnel dont on voudrait, mais ne pourrait, se détacher; d’où la nostalgie que la conscience esthétique éprouve pour lui. D’ordre éminemment transitoire, l’objet suranné est un objet esthétiquement intermédiaire qui s’identifie à une hystérésis formelle autant que fonctionnelle. Dès lors, le suranné assure une continuité esthétique, oriente la conscience vers le passé, actualise l’inactuel et cautionne le rapprochement de ce qui est sujet à distanciation. (shrink)

Positioning accuracy of micropositioning stage in scanning ion conductance microscopy is the key to obtain high-precision scanning model. Most piezoelectric ceramic micromotion platforms are used for that, and hysteresis characteristics are the main reason for the nonlinear characteristics of piezoelectric ceramics and the influence on the control accuracy. In order to solve this problem, backpropagation algorithm based on whale optimization algorithm is used to model the hysteresis, which is directly used as a feedforward controller to compensate the (...) class='Hi'>hysteresis effect, and the robust adaptive moving average control method is used for feedback control. The results show that the hysteresis model of backpropagation algorithm based on the whale optimization algorithm can fit the hysteresis curve well, and the maximum fitting error is 0.2050 μm, only 0.256%. By adopting feedforward and feedback, feedforward robust adaptive moving average control algorithm decreases the hysteresis from 17.64% to 2.51%, which enables the output of the piezoelectric ceramic controller to track the expected displacement well and makes it possible to improve the scanning accuracy.

Most models of response time (RT) in elementary cognitive tasks implicitly assume that the speed-accuracy trade-off is continuous: When payoffs or instructions gradually increase the level of speed stress, people are assumed to gradually sacrifice response accuracy in exchange for gradual increases in response speed. This trade-off presumably operates over the entire range from accurate but slow responding to fast but chance-level responding (i.e., guessing). In this article, we challenge the assumption of continuity and propose a phase transition model for (...) RTs and accuracy. Analogous to the fast guess model (Ollman, 1966), our model postulates two modes of processing: a guess mode and a stimulus-controlled mode. From catastrophe theory, we derive two important predictions that allow us to test our model against the fast guess model and against the popular class of sequential sampling models. The first prediction—hysteresis in the transitions between guessing and stimulus-controlled behavior—was confirmed in an experiment that gradually changed the reward for speed versus accuracy. The second prediction—bimodal RT distributions—was confirmed in an experiment that required participants to respond in a way that is intermediate between guessing and accurate responding. (shrink)

This article challenges what is now the orthodoxy concerning the heritage of Bourdieu (1930–2002): namely, the judgement that his distinctive sociological innovation has been his theory of social reproduction, and that he has failed to provide a necessary theory of social change. Yet Bourdieu consistently claimed to offer a theory of social transformation as well as accounting for continuities of power. Indeed, he provides two substantive keys for an understanding of historical transformation—first, a theory of prophets (religious or secular) as (...) the authors of heresies or “symbolic revolutions” that dispel current doxa; second, a theory of the “corporatism of the universal”: the role of intellectuals or other educated professionals in pursuit of social justice and other universalistic goals. Moreover, Bourdieu fuses his theories of “symbolic revolutions” with a materialist analysis of their social preconditions, including a fresh account of social crises. Crises—war, famine, recession, and especially the intensified precarity of the educated—have, for him, a profound impact, both within differentiated fields and across fields. Conflicts that become effectivelysynchronizedacross fields acquire great resonance within the wider field of power, particularly due to hysteresis or “maladjusted habitus.” Indeed, the appearance of crises, together with new prophetic heresies, leads the subordinate classes to question the taken-for-granted order of things and to orchestrate their resistance. Alongside his corpus of published writings, this article draws widely on Bourdieu’s posthumously published lectures. These cast a distinctive new light on how his well-known conceptual instruments can aid us in the study of historical change. They also expand on how social science itself might be used to facilitate progressive social movements. (shrink)

Dynamical systems theory (DST) is a branch of mathematics that assesses abstract or physical systems that change over time. It has a quantitative part (mathematical equations) and a related qualitative part (plotting equations in a state space). Nonlinear dynamical systems theory applies the same tools in research involving phenomena such as chaos and hysteresis. These approaches have provided different ways of investigating and understanding cognitive systems in cognitive science and neuroscience. The ‘dynamical hypothesis’ claims that cognition is and can (...) be understood as dynamical systems. Common consequences for such an approach include rejecting understanding cognition as information processing in nature, including eschewing explanatory roles for computation or representation. Contemporary applications of DST include mouse‐tracking studies in cognitive science and nonrepresentational perspectives on motor control in neuroscience. Such work has philosophical implications concerning the boundaries of cognition, explanation, and representations. DST offers powerful methodology and theories that raise many topics of philosophical significance. (shrink)
