Lady Mary Shepherd holds that the relation of cause and effect consists of the combination of two objects to create a third object. She also holds that this account implies that causes are synchronous with their effects. There is a single instant in which the objects that are causes combine to create the object which is their effect. Hume argues that cause and effect cannot be synchronous because if they were then the entire chain of successive causes and (...) effects would all collapse into a single moment, and succession would not be possible. I argue that Shepherd has a ready, although implicit response, to Hume’s argument. Since causation is combination on Shepherd’s view, she is free to hold that there are times in between those instants in which combinations occur, during which times other, non-combinatory changes occur, which changes account for succession.

Online research offers advantages including recruitment cost, diminished equity-related participation barriers, and convenience; however, there are growing concerns regarding fraudulent participation. Guidance to navigate these challenges exists for online research generally (e.g. surveys), but remains sparse for the specific challenge of fraudulent participation within virtual synchronous interviews. No work has explored this topic within an explicit, detailed ethical framework. Reflecting on our experiences navigating fraudulent participation in virtual synchronous research, we address this gap using the Canadian Code of (...) Ethics for Psychologists as a guiding framework to describe challenges, explore ethical considerations, and identify potential solutions and research directions. (shrink)

The free-energy principle (FEP) builds on an assumption that sensor–motor loops exhibit Markov blankets in stationary state. We argue that there is rarely reason to assume a system's internal and external states are conditionally independent given the sensorimotor states, and often reason to assume otherwise. However, under mild assumptions internal and external states are conditionally independent given the sensorimotor history.

Temporal epistemic logics are known, from results of Halpern and Vardi, to have a wide range of complexities of the satisfiability problem: from PSPACE, through non-elementary, to highly undecidable. These complexities depend on the choice of some key parameters specifying, inter alia, possible interactions between time and knowledge, such as synchrony and agents' abilities for learning and recall. In this work we develop practically implementable tableau-based decision procedures for deciding satisfiability in single-agent synchronous temporal-epistemic logics with interactions between time (...) and knowledge. We discuss some complications that occur, even in the single-agent case, when interactions between time and knowledge are assumed and show how the method of incremental tableaux can be adapted to work in EXPSPACE, respectively 2EXPTIME, for these logics, thereby also matching the upper bounds obtained for them by Halpern and Vardi.

In this paper, an intelligent neural network-based controller is designed and implemented to control the speed of a permanent magnet synchronous motor. First, the exact mathematical model of PMSM is presented, and then, by designing a controller, we apply the wind turbine emulation challenges. The designed controller for the first time is implemented on a Arm Cortex-M microcontroller and tested on a laboratory PMSM. Since online learning neural network on a chip requires a strong processor, high memory, and convergence (...) guarantee, this article uses the offline method. In this method, first, for different work points, the neural network is trained by local controllers, and then, the trained network is implemented on the chip and used. Uncertainty in the parameters and the effect of load torque as challenges of control systems are applied in the proposed method, and a comparison with other methods is performed in the implementation results section.

Non-governmental organizations often regard expanding revenue and reducing costs as standard procedures to achieve corporate sustainability, while at the same time considering human resources as important assets. Government agencies have greater flexibility in staffing, and their human resource strategies for employee education and training often use organizational learning to develop operational performance. Training is regarded as a panacea for corporate sustainability and channels have been established to support employees' learning. Curriculum development of synchronous online learning is an approach that (...) requires further investigation. We distributed 360 questionnaires to supervisors and employees of the Taipei City Government, Taiwan. A total of 268 valid copies were retrieved, giving a response rate of 74%. The study results are expected to help public sector employers enhance employee cohesiveness and generate more operational team spirit. (shrink)

This paper offers a structural reinterpretation of Jungian synchronicity as a topological and epistemic phenomenon, rather than a psychological anomaly. We argue that meaningful coincidence can be modeled as a form of phase-aligned collapse within a coherence manifold, where causal transmission is replaced by structural resonance. Drawing on parallels with quantum measurement and the Participatory Anthropic Principle, we propose that meaning emerges through observer participation in topologically organized fields of relational significance. Synchronicity thus marks not a violation of causality but (...) a point of epistemic convergence—a non-causal collapse of latent order into intelligible form. This framework advances a post-causal epistemology, wherein coherence supplants causation as the organizing principle of meaning. (shrink)

This article explores the hypothesis that synchronicity—often dismissed as psychological coincidence—can be rigorously interpreted as a phase collapse of semantic superposition, culminating in an epistemic singularity. Departing from classical models, we propose that the observer functions as a recursive, programmable interface whose engagement with the environment operates through phase coherence and reversibility. At moments of synchronicity, non-causal semantic configurations undergo sudden stabilization, enabling a mode of knowing that transcends empirical validation. Measurement is reframed as resonance between external structures and the (...) observer’s internal topology. Synchronicity becomes not a mere coincidence, but a localized collapse of interpretive potential, activated through the intrinsic phase of attention or belief. This framework challenges the foundations of epistemology and proposes a novel model for quantum measurement and scientific cognition. Meaning is constituted not through symbolic processing alone, but through structurally entangled participation—at the edge of what can be known and what can be measured. (shrink)

In this paper, I put forward a benchmark account of emergence in terms of non-explainability and explicate the relationship that exists between its synchronic and diachronic declinations. I develop an argument whose conclusion is that emergence is essentially a “two-faceted” notion, i.e. it always encapsulates both synchronic and diachronic dimensions. I then compare this account with alternative recent accounts of emergence that define the concept through the notion of unpredictability or topological non-equivalence.

The main focus of this paper is on the notion of transtemporal identity applied to quantum particles. I pose the question of how the symmetrization postulate with respect to instantaneous states of particles of the same type affects the possibility of identifying interacting particles before and after their interaction. The answer to this question turns out to be contingent upon the choice between two available conceptions of synchronic individuation of quantum particles that I call the orthodox and heterodox approaches. I (...) argue that the heterodox approach offers a better explanation of the known experimental facts regarding particle interactions, and I probe deeper the concepts of synchronic and diachronic identity emerging from this approach.

Recent advances in neuroimaging technologies have rendered multimodal analysis of operators’ cognitive processes in complex task settings and environments increasingly more practical. In this exploratory study, we utilized optical brain imaging and mobile eye tracking technologies to investigate the behavioral and neurophysiological differences among expert and novice operators while they operated a human-machine interface in normal and adverse conditions. In congruence with related work, we observed that experts tended to have lower prefrontal oxygenation and exhibit gaze patterns that are better (...) aligned with the optimal task sequence with shorter fixation durations as compared to novices. These trends reached statistical significance only in the adverse condition where the operators were prompted with an unexpected error message. Comparisons between hemodynamic and gaze measures before and after the error message indicated that experts’ neurophysiological response to the error involved a systematic increase in bilateral dorsolateral prefrontal cortex (dlPFC) activity accompanied with an increase in fixation durations, which suggests a shift in their attentional state, possibly from routine process execution to problem detection and resolution. The novices’ response was not as strong as that of experts, including a slight increase only in the left dlPFC with a decreasing trend in fixation durations, which is indicative of visual search behavior for possible cues to make sense of the unanticipated situation. A linear discriminant analysis model capitalizing on the covariance structure among hemodynamic and eye movement measures could distinguish experts from novices with 91% accuracy. Despite the small sample size, the performance of the linear discriminant analysis combining eye fixation and dorsolateral oxygenation measures before and after an unexpected event suggests that multimodal approaches may be fruitful for distinguishing novice and expert performance in similar neuroergonomic applications in the field.

We suggest that developing automata theoretic foundations is relevant for knowledge theory, so that we study not only what is known by agents, but also the mechanisms by which such knowledge is arrived at. We define a class of epistemic automata, in which agents’ local states are annotated with abstract knowledge assertions about others. These are finite state agents who communicate synchronously with each other and information exchange is ‘perfect’. We show that the class of recognizable languages has good closure (...) properties, leading to a Kleene-type theorem using what we call regular knowledge expressions. These automata model distributed causal knowledge in the following way: each agent in the system has a partial knowledge of the temporal evolution of the system, and every time agents synchronize, they update each other’s knowledge, resulting in a more up-to-date view of the system state. Hence we show that these automata can be used to solve the satisfiability problem for a natural epistemic temporal logic for local properties. Finally, we characterize the class of languages recognized by epistemic automata as the regular consistent languages studied in concurrency theory. (shrink)

Objections to functional explanations of awareness assert that although functional systems may be adequate to explain behavior, including verbal behavior consisting of assertions of awareness by an individual, they cannot provide for the existence of phenomenal awareness. In this paper, a theory of awareness is proposed that counters this assertion by incorporating two advances: (1) a formal definition of representation, expressed in a functional notation: Newell's Representation Law, and 2) the introduction of real time into the analysis of awareness. This (...) leads to the definition of phenomenal awareness as existing whenever an object contains an autonomously updated configuration satisfying the Representation Law with respect to some aspects of its environment. The relational aspect of the Representation Law permits the development of multiple levels of awareness, which provides for the existence of illusions and hallucinations, and permits the identification of a new measure, accuracy of awareness . The relational perspective also permits the incorporation of referential concepts into the framework. Qualia can then be identified with referentially opaque elements of awareness. The functional form of the Representation Law is linked to neurophysiology and the underlying phenomena of chemistry and physics by phenomena involving activity-dependent connectivity. (shrink)

This paper distinguishes between synchronic responsibility (SR) and diachronic responsibility (DR). SR concerns an agent’s responsibility for an act at the time of the action, while DR concerns an agent’s responsibility for an act at some later time. While most theorists implicitly assume that DR is a straightforward matter of personal identity, I argue instead that it is grounded in psychological connectedness. I discuss the implications this distinction has for the concepts of apology, forgiveness, and punishment as well as the (...) way in which this distinction can be used to defend quality of will accounts of responsibility against objections involving psychological manipulation. I argue that the intuition that a manipulated agent is not responsible can be explained by appeal to the conditions of DR and, as such, does not unproblematically shed light on the conditions of SR.

In this chapter I argue that the necessity of the present counts against theories of synchronic free will, according to which a person may have free will at a time t0 even once that person has decided at t0 to do something. I defend the theory of diachronic free will against recent critiques drawn from the work of Michael Rota and Katherin Rogers. And I chart some of the implications for the philosophy of religion.

There are two main ways to teach a course online: synchronously or asynchronously. In an asynchronous course, students can log on at their convenience and do the course work.

In this article, the author discusses the strengths and weaknesses of synchronous online learning for the teaching of undergraduate philosophy courses. The author discusses specific strategies and (...) technologies he uses in the teaching of online philosophy courses. In particular, the author discusses how he uses videoconferencing to create a classroom-like environment in an online class. (shrink)

The axiomatic bases of Special Relativity Theory (SRT) are thoroughly re-examined from an operational point of view, with particular emphasis on the status of Einstein synchronization in the light of the possibility of arbitrary synchronization procedures in inertial reference frames. Once correctly and explicitly phrased, the principles of SRT allow for a wide range of “theories” that differ from the standard SRT only for the difference in the chosen synchronization procedures, but are wholly equivalent to SRT in predicting empirical facts. (...) This results in the introduction, in the full background of SRT, of a suitable synchronization gauge. A complete hierarchy of synchronization gauges is introduced and elucidated, ranging from the useful Selleri synchronization gauge (which should lead, according to Selleri, to a multiplicity of theories alternative to SRT) to the more general Mansouri–Sexl synchronization gauge and, finally, to the even more general Anderson–Vetharaniam–Stedman’s synchronization gauge. It is showed that all these gauges do not challenge the SRT, as claimed by Selleri, but simply lead to a number of formalisms which leave the geometrical structure of Minkowski spacetime unchanged. Several aspects of fundamental and applied interest related to the conventional aspect of the synchronization choice are discussed, encompassing the issue of the one-way velocity of light in inertial and rotating reference frames, the global positioning system (GPS)’s working, and the recasting of Maxwell equations in generic synchronizations. Finally, it is showed how the gauge freedom introduced in SRT can be exploited in order to give a clear explanation of the Sagnac effect for counter-propagating matter beams. (shrink)

The human brain consists of approximately 100 billion electrically active neurones that generate an endogenous electromagnetic field, whose role in neuronal computing has not been fully examined. The source, magnitude and likely influence of the brain's endogenous em field are here considered. An estimate of the strength and magnitude of the brain's em field is gained from theoretical considerations, brain scanning and microelectrode data. An estimate of the likely influence of the brain's em field is gained from theoretical principles and (...) considerations of the experimental effects of external em fields on neurone firing both in vitro and in vivo. Synchronous firing of distributed neurones phase-locks induced em field fluctuations to increase their magnitude and influence. Synchronous firing has previously been demonstrated to correlate with awareness and perception, indicating that perturbations to the brain's em field also correlate with awareness. The brain's em field represents an integrated electromagnetic field representation of distributed neuronal information and has dynamics that closely map to those expected for a correlate of consciousness. I propose that the brain's em information field is the physical substrate of conscious awareness - the cemi field - and make a number of predictions that follow from this proposal. Experimental evidence pertinent to these predictions is examined and shown to be entirely consistent with the cemi field theory. This theory provides solutions to many of the intractable problems of consciousness - such as the binding problem - and provides new insights into the role of consciousness, the meaning of free will and the nature of qualia. It thus places consciousness within a secure physical framework and provides a route towards constructing an artificial consciousness. (shrink)

I discuss here a number of different kinds of diachronic emergence, noting that they differ in important ways from synchronic conceptions. I argue that Bedau’s weak emergence has an essentially historical aspect, in that there can be two indistinguishable states, one of which is weakly emergent, the other of which is not. As a consequence, weak emergence is about tokens, not types, of states. I conclude by examining the question of whether the concept of weak emergence is too weak and (...) note that there is at present no unifying account of diachronic and synchronic concepts of emergence.

An agent exercises instrumental rationality to the degree that she adopts appropriate means to achieving her ends. Adopting appropriate means to achieving one’s ends can, in turn, involve overcoming one’s strongest desires, that is, it can involve exercising synchronic self-control. However, contra prominent approaches, I deny that synchronic self-control is possible. Specifically, I draw on computational models and empirical evidence from cognitive neuroscience to describe a naturalistic, multi-system model of the mind. On this model, synchronic self-control is impossible. Must we, (...) then, give up on a meaningful conception of instrumental rationality? No. A multi-system view still permits something like synchronic self-control: an agent can control her very strong desires. Adopting a multi-system model of the mind thus places limitations on our conceptions of instrumental rationality, without requiring that we abandon the notion altogether. (shrink)

For synchronization of a class of chaotic systems in the presence of nonvanishing uncertainties, a novel time-varying gain observer-based sliding mode control is proposed. First, a novel time-varying gain disturbance observer is developed to estimate the uncertainties. Then, by using the output of TVGDO to modify sliding mode control, a new TVGDO-based SMC scheme is developed. Although the observation and control precision of conventional fixed gain disturbance observer-based control for chaotic systems can be guaranteed by a high observer gain, the (...) undesirable spike problem may be caused by the high gain if the initial values of estimate and true states are not equal. The most attractive feature of this work is that the newly proposed TVGDO can eliminate the spike problem by developing a time-varying gain scheme. Finally, the effectiveness of the proposed method is demonstrated by the numerical simulation. (shrink)

This paper argues that interpersonal synchronization of physiological and motor rhythms constitutes the earliest and most basic mechanism of communication and meaning formation. Drawing on empirical work in developmental psychology and neuroscience, phenomenological analyses of intersubjectivity, and accounts of embodied social interaction, it proposes that temporal coordination between bodies affords a minimal, non-conceptual form of sense-making that precedes symbols, concepts, and linguistic articulation. On this view, meaning does not originate in detached cognitive representations but arises within shared temporal structures enacted (...) through bodily attunement. On this basis, the paper further contends that disruptions of rhythmic synchronization can have distinctive epistemic consequences. Engaging phenomenological accounts of intercorporeality, particularly those developed by Merleau-Ponty, it suggests that the recognition of others as epistemic agents depends upon pre-reflective, bodily modes of attunement. When this intercorporeal ground is destabilized, as in schizophrenia, the conditions of mutual intelligibility are compromised. The resulting difficulties cannot be reduced to deficits in communication or social cognition alone; they extend into the epistemic domain, where individuals may cease to be readily acknowledged as knowers.

Observational learning can enhance the acquisition and performance quality of complex motor skills. While an extensive body of research has focused on the benefits of synchronous (i.e., concurrent physical practice) and non-synchronous (i.e., delayed physical practice) observational learning strategies, the question remains as to whether these approaches differentially influence performance outcomes. Accordingly, we investigate the differential outcomes of synchronous and non-synchronous observational training contexts using a novel dance sequence. Using multidimensional cross-recurrence quantification analysis, movement time-series were (...) recorded for novice dancers who either synchronised with (n = 22) or observed and then imitated (n = 20) an expert dancer. Participants performed a 16-count choreographed dance sequence for 20 trials assisted by the expert, followed by one final, unassisted performance trial. Although end-state performance did not significantly differ between synchronous and non-synchronous learners, a significant decline in performance quality from imitation to independent replication was shown for synchronous learners. A non-significant positive trend in performance accuracy was shown for non-synchronous learners. For all participants, better imitative performance across training trials led to better end-state performance, but only for the accuracy (and not timing) of movement reproduction. Collectively, the results suggest that synchronous learners came to rely on a realtime mapping process between visual input from the expert and their own visual and proprioceptive intrinsic feedback, to the detriment of learning. Thus, the act of synchronising alone does not ensure an appropriate training context for advanced sequence learning. (shrink)

The topic of synchronicity has long intrigued philosophers, scientists, and the general public. However, to date very little empirical research has explored the underlying mechanisms of synchronicity. In other words, why do synchronicities occur? Are synchronicities random, or do they hold clues about the ultimate nature of reality? Drawing on theoretical and empirical research, the current paper explores the idea that synchronicity might be one way that the fundamental (i.e. ontologically primary) nature of consciousness reveals itself to us in everyday (...) life, and that contemplative practices such as meditation might be capable of invoking synchronicity. In addition, this paper aims to summarize theoretical perspectives on synchronicity in an attempt to spark a renewed interest in conducting empirical research on this topic, arguing for a thoughtful consideration of post-materialist perspectives in an attempt to innovate within the field of consciousness studies and shed light on the ontological questions raised by synchronicity.

This paper explicates two notions of emergencewhich are based on two ways of distinguishinglevels of properties for dynamical systems.Once the levels are defined, the strategies ofcharacterizing the relation of higher level to lower levelproperties as diachronic and synchronic emergenceare the same. In each case, the higher level properties aresaid to be emergent if they are novel or irreducible with respect to the lower level properties. Novelty andirreducibility are given precise meanings in terms of the effectsthat the change of a bifurcation (...) or perturbation parameterin the system has. (The same strategy can be applied to otherways of separating levels of properties, like themicro/macro distinction.)The notions of emergence developed here are notions of emergencein a weak sense: the higher level emergent properties wecapture are always structural properties (or are realized insuch properties), that is, they are defined in terms of the lowerlevel properties and their relations. Diachronic and synchronicemergent properties are distinctions within thecategory of structural properties. (shrink)

Reasoning is an activity of ours by which we come to satisfy synchronic requirements of rationality. However, reasoning itself is regulated by diachronic permissions of rationality. For each synchronic requirement there appears to be a corresponding diachronic permission, but the requirements and permissions are not related to each other in a systematic way. It is therefore a puzzle how reasoning according to permissions can systematically bring us to satisfy requirements.

In `Underestimating Self-Control' (1997a), I argued that Jeanette Kennett and Michael Smith (1996) underestimate our capacity for synchronic self-control. They argued for a solution to a puzzle about such self-control that features non-actional exercises' of self-control. I argued in response that `a more robust, actional exercise of self-control is open to agents in scenarios of the sort in question' (1997a: 119). They disagree (Kennett and Smith 1997).In Mele 1997a, I resisted the temptation to criticize Kennett and Smith's attempted resolution, because (...) I thought it better to concentrate on sketching an alternative resolution. Here, I will argue that the resolution they offer is problematic and reply to their criticism (1997) of my suggested resolution. (shrink)

Synchronization of autonomic arousal levels within dyads and larger teams has been associated with several types of social-behavioral outcome. One previous study reported greater physiological influence of leaders on followers than of followers on leaders; influence was measured pairwise within triadic problem solving groups. The present study explored synchronized autonomic arousal with leadership outcomes in two experiments with group sizes of three to eight members. Drivers, who had the greatest physiological impact on other team members were consistently less like the (...) leader of the group. Empaths, who were the most receptive to autonomic signals from others, were not consistently associated with leadership roles, although they did show sensitivity to team dynamics in their ratings of cognitive and social sources of workload. The tentative conclusion, subject to future research, is that successful leadership requires a balance between the driver and empath orientations. (shrink)

The pioneering analysis of synchronicity was given by Jung, yet despite the concept's momentous significance in Jung's work, and despite the widespread dissemination of the term 'synchronicity' even within pop culture, synchronicity is often badly misconstrued and remains "perhaps the least understood of Jung's theories". Synchronicity, Science, and Soul-Making has already been hailed as the most important analysis of synchronicity since Jung himself.

Synchronicity IIn the summer of 2006, I read several books by well-known existential psychiatrist and insightful novelist Irvin Yalom.2 They were all thought-provoking and mightily entertaining. Dr. Yalom sustains lively interests in philosophical aspects of psychiatry, as well as in psychiatric aspects of philosophy. Among other works, he has written two profoundly philosophical novels, namely The SchopenhauerCure and When Nietzsche Wept, in which he has delved deeply and creatively into the psyches of these two outstanding thinkers via the refracting media (...) of literary and historical fiction, and through lenses of eclectic existential psychiatry.Yalom’s fictive excursions are not confined to philosophical realms—far from it. In a delightfully ironic novel entitled Lying on the Couch Yalom takes to task some perennially unfinished business of psychoanalysis, namely analysts’ perpetual struggles with counter-transference issues. Even the most seasoned psychoanalysts, so Yalomartfully reveals, have not yet had their own egos sufficiently shrunk. In consequence, they are apt to experience all kinds of problems with patients, and not always of the patients’ making. To be sure, patients are wont to deceive their analysts at times, whether subconsciously, diffidently, or maliciously. And analysts themselves are prone to all the vanities catalogued by Ecclesiastes in antiquity,3 egoisms and egotisms alike that appear innately rooted in the human psyche, and which inevitably contribute to self-deception. If an analyst’s vanities, self-deceptions, and unresolved counter-transferences were skillfully exploited by a professional con-artist posing as a patient, personal and professional mayhemwould result. This is one of the conspicuous threads in the rich tapestry of untruths, vanities and self deceptions that Yalom weaves in Lying on The Couch.One particular episode in Yalom’s novel rather jarred me when I encountered it in August 2006, because it coincided with an uncannily similar episode that was unfolding in my own life at precisely the same time.
