An object in continuous motion is perceived ahead of the briefly flashed object, although the two images are physically aligned , the phenomenon called flash-lag effect. Flash-lag effects have been found also with other continuously changing features such as color, pattern entropy, and brightness as well as with streamed pre- and post-target input without any change of the feature values of streaming items in feature space . We interpret all instances of the flash-lag as a consequence of a more fundamental (...) property of conscious perception in general: acceleration of the speed with which samples of perceptual information become represented in explicit format immediately after the stimulation onset. Decreased visual latency of the samples of stimulus information from the streamed input leads to the relative perceptual lag for the separately flashed stimulus because it is not preceded by adjacent sensory input that would have accelerated its perception. Experimental support for the notion of perceptual acceleration is reviewed. (shrink)

A great amount of literature documents young children’s innate interest in discovering their surroundings and gradually developing more complex activities and thoughts. It has been demonstrated that when environments support young children’s innate interest and progressive autonomy, they help children acquire a self-determined behavior. However, little is known about the application of this evidence in the daily practice of early childhood educational settings. This study examines Emmi Pikler Nursery School, a center that implements an autonomy-supportive educational approach. We conducted a (...) systematic observation of two experienced Pikler educators while they accompanied young children’s free play. Our objective was to assess: if educators’ instrumental action follows a systematic behavioral sequence; if each instrumental action is supported by specific relational behaviors; and if educators display differentiated intervention levels with regards to children’s free play through the adaptation of the relational dimension. We conducted lag sequential analysis in order to find behavioral patterns and concurrences between the observed behaviors. Our findings indicate that educators perform systematic action sequences and that each of the instrumental actions of those sequences has a specific relational value. We conclude that educators display three differentiated intervention levels depending on the child and the circumstances of the moment, providing an appropriate autonomy support and reinforcing children’s self-determination.

It is widely accepted that ethical leadership is beneficial for the organization, the leader, and followers. Yet, little has been said about potential limitations of ethical leadership, particularly boundary conditions involving the same person perceived to display ethical leadership. Drawing on conservation of resources theory, we argue that supervisor-induced hindrance stress and job hindrance stress are factors linked to the supervisor and work environment that may limit the positive impact of ethical leadership on employee deviance and turnover intentions. Specifically, (...) we expect that high levels of hindrance stress drain resources, specifically perceptions of social support, by inhibiting the completion of work, particularly in combination with the high expectations of ethical leaders. We test our model across two time-lagged field studies. Our results demonstrate that supervisor-induced hindrance stress mitigates some of the beneficial impact of ethical leadership and that job hindrance stress further strains these relationships. Overall, our results suggest that both forms of hindrance stress jointly impact the effectiveness of ethical leadership on important outcomes, and do so partly because of their influence on perceived social support. We discuss theoretical contributions to the ethical leadership and stress bodies of literature, as well as practical implications for managers and organizations wishing to develop ethical leaders.

Although artistic activity has been a major social phenomenon in the western world, aesthetics has not always reflected the changes in techniques, processes, themes and uses through which the arts have developed and had their effect. Theory most often comes after the fact, and properly so. Yet aesthetics in its history has not only displayed an unfitting hubris, with thinkers attempting to legislate about style, suitability and materials to the artist; aesthetics has also lagged far behind the living edge of (...) artistic activity and discussed it in anachronistic terms.

Abusive supervision, defined as subordinates’ perception of the extent to which supervisors engage in the sustained display of hostile verbal and non-verbal behaviors, excluding physical contact, is associated with various negative outcomes. This has made it easy for researchers to overlook the possibility that some supervisors regret their bad behavior and express remorse for their actions. Hence, we know little about how subordinates react to the perception that their supervisor is remorseful and how this perception affects the outcomes of (...) supervisors’ undesired behavior. Specifically, drawing on the social exchange theory and displace revenge literature, this study explains how abusive supervision leads to victims’ service sabotage behavior. In addition, this study also investigates how perceived supervisors’ remorse mitigates the adverse effects of abusive supervision. Based on time-lagged, dyadic data from Chinese individuals, this study found support for all the proposed relationships, i.e., abusive supervision leads to service sabotage through the mediating effect of revenge desire. The findings also conclude that PSR lessens the detrimental effects of abusive supervision on victims’ behavior with their customers. Finally, this research contributes to service sabotage literature by highlighting the possibility where abusive supervisors cause service sabotage behavior among victims. This study also shows the importance of PSR’s role in decreasing service sabotage behavior exhibited by victims of abusive supervisors in the service sector. (shrink)

Drawing on Conservation of resources (COR) theory, this study examined the underlying mechanism through which workplace bullying (WB) affects employees’ life satisfaction via job- related anxiety and insomnia. Time-lagged data were collected at two points in time from 211 doctor interns working in various hospitals in Pakistan. Results fully support a proposed serial multiple-mediator model. Workplace bullying is indirectly related to life satisfaction via job-related anxiety and insomnia. This study provides evidence of a spillover effect as to how workplace bullying (...) increases employees’ job-related anxiety which in turn leads to insomnia resulting in reduced employees’ life satisfaction. The present study extends research on workplace bullying to display its theoretical as well as empirical effects on life satisfaction. It demonstrates that workplace bullying as an occupational and psychological stressor has multiple effects on employees’ life satisfaction through a serial mediation model in the context of a developing country. It further explains that workplace bullying not only affects an employee’s workplace behaviors but also extends to the employee’s over-all life satisfaction. Keywords: Workplace bullying, job-related anxiety, insomnia, life satisfaction. (shrink)

The aim of this paper is to describe Dewey’s reception in the Spanish-speaking countries that constitute the Hispanic world. Without any doubt, it can be said that in the past century Spain and the countries of South America have been a world apart, lagging far behind the mainstream Western world. It includes a number of names and facts about the early translation of Dewey’s works in Spain, Chile, Cuba, Mexico and Argentina in the first half of the century and a (...) brief explanation of the decline of Dewey in the second half. To a great extent, Dewey’s conception of education was immersed in the international movement of reform that started at the turn of the century and would eventually slowly but surely, renovate the structure of the educational system throughout the entire century, including that of South America. But it is equally clear that the Spanish-speaking countries have displayed a general ignorance of Dewey and, by extension, of American pragmatism during most of the century. In spite of mutual incomprehension, a deep affinity between Dewey’s pragmatism and Hispanic philosophy is suggested in this paper, anticipating that the gradual process of democratization of Spain and the Hispanic countries of South America may be in some sense related to the rediscovery of Dewey and to the application of his key ideas in education. After decades of neglect of Dewey and of his contribution, there is a strong feeling not only that his conception of things is important to understand the last century but that Dewey – along with Peirce and other American classical pragmatists – may very well prove to be a key thinker for the XXIst century also in the Hispanic world. Along this vein, the recent resurgence of pragmatism can be understood not as the latest academic fashion but the occasion to start to close the gap between the two worlds. (shrink)

The comparison of growth, whether it is between different strains or under different growth conditions, is a classic microbiological technique that can provide genetic, epigenetic, cell biological, and chemical biological information depending on how the assay is used. When employing solid growth media, this technique is limited by being largely qualitative and low throughput. Collecting data in the form of growth curves, especially automated data collection in multi‐well plates, circumvents these issues. However, the growth curves themselves are subject to stochastic (...) variation in several variables, most notably the length of the lag phase, the doubling rate, and the maximum expansion of the culture. Thus, growth curves are indicative of trends but cannot always be conveniently averaged and statistically compared. Here, we summarize a simple method to compile growth curve data into a quantitative format that is amenable to statistical comparisons and easy to graph and display. (shrink)

In April 2020, almost six out of 10 people around the world were in lockdown due to the COVID-19 pandemic. Being locked down usually has a deleterious effect on the confined individual's mental health. In this exceptionally challenging context, finding ways to minimize negative mood about the pandemic is essential. Pandemic-related negative states (“negative mood”) and recovery experiences were investigated in a sample of 264 individuals who completed daily surveys four times per day over 7 consecutive days. MSEMs analyses revealed (...) that negative mood persisted from moment-to-moment through the day, thus showing a response lag effect. Further analyses revealed that when someone experienced pandemic-related psychological detachment, relaxation, mastery, control, pleasure, or relatedness at specific periods of the day, mood had improved at the next measured time period, suggesting a protective effect. However, the pattern displayed by singles with dependents suggests that some recovery experiences at specific periods during the day seem to have a backfiring effect and worsen subsequent mood. These findings bring new insight into the role of recovery experiences during lockdowns and suggest that many could benefit from such experiences throughout the day when self-isolating. However, for individuals with multiple risk factors such as being single with dependents, some recovery experiences, at specific periods during the day, might not bring the desired outcome and future research is needed to examine if guilt or domestic burden may explain this finding. Results contribute to our understanding of how to take care of one's mental health during the current pandemic, and concrete recommendations adapted to individual contexts are provided. (shrink)

The original, prescientific Western belief that the mantis is a pious, helpful creature became a widely held explanation for the mantid's unique resting posture, and for one of its cryptic displays. This belief was a characteristic part of a broader discourse about nature in which ancient authority, religious beliefs, and superstition, but few original observations, mixed freely. Gradually, the belief in mantid gentleness and piousness became a commonplace through the continual retelling of the myths and superstitions surrounding this fascinating insect.By (...) the seventeenth century, a growing interest in observation had begun to replace blind reliance on established wisdom and ancient authority. However, the various young sciences to which the period gave rise did not progress equally, and neither did the subdisciplines within each scientific field; biology, especially entomology, was particularly slow to free itself from past beliefs and contemporary superstitions. In the specific case of the praying mantis, the situation may have been at its worst.Early observers of nature found evidence that seemed, at first, to disconfirm the well-established belief that mantids are gentle creatures. These few observers, faced with startling firsthand information about mantid voraciousness, created a new characterization of mantids as merciless predators and then often juxtaposed the two images in their descriptions. However, it was not until the beginning of the nineteenth century that the two characterizations-gentleness versus cruelty— became reconciled.An amalgamation of these seemingly mutually exclusive characterizations was achieved by an interesting accommodation of each to the other. That is, while it could no longer be maintained that mantids are simply gentle insects, neither could it be accepted that they are all cruelty and viciousness. The melding of the two characterizations yielded a hybrid explanation which claimed that the praying mantis actually hastwo sides to its character! On the one hand, and like other creatures, mantids must nourish themselves, and do so quite reasonably by capturing small insects for food. However, even when “well nourished,” and without “the excuse of hunger,” their other, vicious side may surface; when this happens, the darkest of behaviours, cannibalism, is the result.To understand the remainder of the story one must pause to consider what had happened in the other sciences up to this point. In the mid-seventeenth century, professional scientific societies were established throughout Europe. The societies, and the various journals and periodicals that they produced or encouraged, represented an institutionalization of both science and its special, structured discourse. However, as we have stated, entomology lagged behind; and in the case of some insects, superstitions and anthropomorphisms did not fade from descriptions of their behavior for centuries to come.By the time the new scientific discourse was applied to mantids the creatures were already firmly shackled with a dual personality, and this assumption was never challenged. In fact, it was functionally impossible to disconfirm. Captures of small prey were considered part of the mantid's normal side; captures of large prey were considered part of the mantid's abnormal side. There was no alternative explanation.As luck would have it, by the time that the strictures of scientific discourse had tightened sufficiently to disallow the use of anthropomorphisms in the explanation of insect behavior, another acceptable explanation of mantid cannibalism became immediately available: cannibalism became part of mantid mating behavior. That is, the fundamental explanatory model remained unchanged; it was merely couched in more appropriate terms. The acceptance of this new explanation for cannibalism was virtually immediate and complete. For instance, no one ever asked the following questions: If the headless male remains able to mate as a putative precaution against female cannibalism, for what reason does the headless female remain able to fashion “a perfectly constructed ootheca”? Or: If female-on-male cannibalism plays a role in mating behavior, what role is played by genderindifferent cannibalism, especially that among immature mantids? The latter phenomena were simply ignored — they were just uninteresting artifacts of insect life. However, the grand logic of nature was immediately apparent in the headless male's ability to mate. The ruling theory, to use Chamberlin's term, had been able to accommodate itself to, and assimilate, the new scientific discourse. It remained unscathed.A persistent question posed by several historians of this particular topic has been, Why did not the results of Ken Roeder's experiments debunk the myth that males are regularly cannibalized by the females with which they mate? The reason, which we hope is now clear, is that there were two interdependent ruling theories operating here. If one accepts the argument that mantids' cannibalism is simply a normal part of their prey-catching behavior, then one attacks not only the theory that mantids have two separate predatory strategies, but also the more recent theory that mantids have evolved to be the ideal fly-catching machines. This second theory found its first confirming support in the centuries-old practice of feeding flies to captive mantids. Again, the disconfirming evidence of mantids eating prey of various sizes had no impact on the theory. Confirming observations were accepted: disconfirming observations were seen as anomalies.Additional confirmation of both ruling theories was garnered in experiments done in the mid-twentieth century. These experiments were based on the assumption that the original conceptualizations were correct, and consequently they did not test other hypotheses. The combined strength of the two theories is evidenced especially in the Raus' failure to account for the fact that their empirical observations were at odds with many of the conclusions that they drew, and in the fact that Roeder's work is still used to support the belief in the regularity of mating-related cannibalism despite the fact that Roeder, himself, argued the opposite. with both theories well entrenched, it is virtually impossible to promote an alternative theory of mantid behavior: namely, that mantids are generalized, opportunistic predators that manage to survivein spite of the fact that cannibalism sometimes occurs.

The time-lag argument seems to put some pressure on naïve realism to agree that seeing must happen simultaneously with what is seen; meanwhile, a wide-accepted empirical fact suggests that light takes time to transmit from objects at a distance to perceivers—which implies what is seen happened before seeing, and, accordingly, naïve realism must be false. In this paper, I will, first of all, show that the time-lag argument has in fact involves a misunderstanding concept of simultaneity: according to Special Relativity, (...) simultaneity is a matter of convention rather than a matter of fact, so, in principle, we can stipulate a perceptual conception of simultaneity, according to which what is seen is simultaneous with seeing. Secondly, the generalized time-lag argument has a mistaken view on the perceived events and perceiving; it has a doubtful assumption that these events are momentary in the mathematical sense. Such idealization is the main reason why we have the intuition that the time-lag effect of perceiving is in conflict with our ordinary perceptual experiences. Finally, I argue that the naïve realist account of the perceptual relation is a nontemporal constitutive relation; and hence naïve realism is compatible with the claim that we can perceive things as they were, and it should not be weakened by the time-lag argument.

In the flash-lag effect a non-moving object is quickly flashed directly underneath a moving object, which leads us to perceive the non-moving object as “lagging” the moving object, even though the two objects actually occupy the same horizontal position at the time of the flash. In the example above, for instance, a red square moves across a screen. At the midpoint of the red square’s journey from one side to the other, a green square is quickly presented (flashed) just below. (...) Despite the fact that the two stimuli are presented at the same coordinates along the x axis, the stationary square is perceived as behind the moving square. The perceived lag of the flashed stationary object becomes greater when the speed of the moving object is increased and vice versa (Nijhawan 1994). (shrink)

An important question about eye-movement behavior is when the decision is made to terminate a fixation and program the following saccade. Different approaches have found converging evidence in favor of a mixed-control account, in which there is some overlap between processing information at fixation and planning the following saccade. We examined one interesting instance of mixed control in visual search: lag-2 revisits, during which observers fixate a stimulus, move to a different stimulus, and then revisit the first stimulus on the (...) next fixation. Results show that the probability of lag-2 revisits occurring increased with the number of target-similar stimuli, and revisits were preceded by a brief fixation on the intervening distractor stimulus. We developed the Efficient Visual Sampling computational model to simulate our findings and to provide insight into mixed control of fixations and the perceptual, cognitive, and motor processes that produce lag-2 revisits.

The COVID-19 pandemic has led to an increase in an array of mental health problems. Previous research has shown that media exposure to stressful situations is often related to anxiety and stress. However, given that most existing work has used cross-sectional designs, less is known about the interplay of media exposure and worry as they unfold during sustained exposure to a collective stressor. The current study examined bidirectional associations between COVID-related worry and media consumption over a three-month period. Participants were (...) 87 community adults, the majority of whom were recruited from communities heavily impacted by the COVID-19 pandemic. For three consecutive months, participants asked to indicate how much time they spent worrying and consuming news about the COVID-19 pandemic on a scale from 1 to 5. Cross-lagged analyses revealed that Pandemic Worry at Month 1 predicted increases in Pandemic Media Consumption at Month 2, which in turn predicted increases in Pandemic Worry at Month 3. Findings suggest that media consumption may be a maladaptive coping strategy that has the iatrogenic effect of increasing worry. Clarifying the causal associations between anxiety-perpetuating processes and media consumption may have important clinical implications for understanding and treating mental health during health pandemics.

We introduce translations between display calculus proofs and labeled calculus proofs in the context of tense logics. First, we show that every derivation in the display calculus for the minimal tense logic Kt extended with general path axioms can be effectively transformed into a derivation in the corresponding labeled calculus. Concerning the converse translation, we show that for Kt extended with path axioms, every derivation in the corresponding labeled calculus can be put into a special form that is (...) translatable to a derivation in the associated display calculus. A key insight in this converse translation is a canonical representation of display sequents as labeled polytrees. Labeled polytrees, which represent equivalence classes of display sequents modulo display postulates, also shed light on related correspondence results for tense logics. (shrink)

3D FORMOTION, a unified cortical model of motion integration and segmentation, explains how brain mechanisms of form and motion processing interact to generate coherent percepts of object motion from spatially distributed and ambiguous visual information. The same cortical circuits reproduce motion-induced distortion of position maps, including both flash-lag and flash-drag effects.

We define cut-free display calculi for knowledge logics wherean indiscernibility relation is associated to each set of agents, andwhere agents decide the membership of objects using thisindiscernibility relation. To do so, we first translate the knowledgelogics into polymodal logics axiomatised by primitive axioms and thenuse Kracht's results on properly displayable logics to define thedisplay calculi. Apart from these technical results, we argue thatDisplay Logic is a natural framework to define cut-free calculi for manyother logics with relative accessibility relations.

We introduce an effective translation from proofs in the display calculus to proofs in the labelled calculus in the context of tense logics. We identify the labelled calculus proofs in the image of this translation as those built from labelled sequents whose underlying directed graph possesses certain properties. For the basic normal tense logic Kt, the image is shown to be the set of all proofs in the labelled calculus G3Kt.

ABSTRACT It has become standard to conceive of metalinguistic disagreement as motivated by a form of negotiation, aimed at reaching consensus because of the practical consequences of using a word with one content rather than another. This paper presents an alternative motive for expressing and pursuing metalinguistic disagreement. In using words with given criteria, we betray our location amongst social categories or groups. Because of this, metalinguistic disagreement can be used as a stage upon which to perform a social identity. (...) The ways in which metalinguistic disagreements motivated in this way diverge in character from metalinguistic negotiations are described, as are several consequences of the existence of metalinguistic disagreements motivated in this way.

The present monograph is a slightly revised version of my Habilitations schrift Proof-theoretic Aspects of Intensional and Non-Classical Logics, successfully defended at Leipzig University, November 1997. It collects work on proof systems for modal and constructive logics I have done over the last few years. The main concern is display logic, a certain refinement of Gentzen's sequent calculus developed by Nuel D. Belnap. This book is far from offering a comprehensive presentation of generalized sequent systems for modal logics broadly (...) conceived. The proof-theory of non-classical logics is a rapidly developing field, and even the generalizations of the ordinary notion of sequent listed in Chapter 1 can hardly be presented in great detail within a single volume. In addition to further investigating the various approaches toward generalized Gentzen systems, it is important to compare them and to discuss their relative advantages and disadvantages. An initial attempt at bringing together work on different kinds of proof systems for modal logics has been made in [188]. Another step in the same direction is [196]. Since Chapter 1 contains introductory considerations and, moreover, every remaining chapter begins with some surveying or summarizing remarks, in this preface I shall only emphasize a relation to philosophy that is important to me, register the sources of papers that have entered this book in some form or another, and acknowledge advice and support.

Many logics in the relevant family can be given a proof theory in the style of Belnap's display logic. However, as originally given, the proof theory is essentially more expressive than the logics they seek to model. In this paper, we consider a modified proof theory which more closely models relevant logics. In addition, we use this proof theory to show decidability for a large range of substructural logics.

We compare several methods of implementing the display (sequent) calculus RA for relation algebra in the logical frameworks Isabelle and Twelf. We aim for an implementation enabling us to formalise within the logical framework proof-theoretic results such as the cut-elimination theorem for RA and any associated increase in proof length. We discuss issues arising from this requirement.

Hölderlin’s „Urteil und Sein“ is certainly one of the most intensively discussed fragments in German Idealism. Since Dieter Henrich’s influential interpretation from 1965 it is firmly believed that Urteil und Sein represents a key reference for a unique and „courageous attack“ on Fichte’s principle of philosophy, the „Ich“ of the intellectual intuition. According to Henrich and his followers, Hölderlin argues that the principle of philosophy ought to be „Sein“ instead of „Ich“. In contrast to Henrich, I believe that Urteil und (...) Sein does not contain any kind of critical remarks on Fichte’s philosophy at all. To follow my argumentation, it is only required to avoid the confusion between the content of the intellectual intuition and self-consciousness.Hölderlins Fragment Urteil und Sein zählt zu den bedeutendsten Dokumenten der klassischen deutschen Philosophie und ist seit Henrichs wirkungsmächtiger Interpretation 1965/66 von nahezu allen namhaften deutschen Idealismusforschern Henrichkonform interpretiert worden. Es gilt als einmalige Referenz für eine ebenso einmalige Kritik am Subjekt als Prinzip der Philosophie – namentlich an Fichtes Prinzip. In diesem Diskussionsbeitrag werfe ich die Frage auf, ob dies wirklich der Fall ist, und vertrete die These, dass in Urteil und Sein keinerlei Kritik an Fichtes Philosophie nachweisbar ist. Meine Argumentation beruht auf der Unterscheidung zwischen dem „Ich“ als gedanklichen Gehalt der intellektuellen Anschauung und dem Selbstbewusstsein als Ausdruck der reflexiven Gewahrwerdens seiner selbst im Bewusstsein, nämlich „Ich bin Ich“.

This article contributes to ongoing studies in conversation analysis dealing with the way in which epistemic authority is displayed, claimed, contested and negotiated in social interaction. More particularly, it focuses on the articulation between action format, sequential organization, membership categorization and epistemic authority. The article offers an empirical analysis of the way in which knowledge is distributed and recognized in social gatherings, with a special focus on guided visits. Guided visits are a perspicuous setting for this analysis, since it is (...) an activity in which the guide displays knowledge in comments and explanations and the guided seeks for knowledge in questions. However, this distribution of knowledge is regularly challenged. The article offers a systematic study of a collection of sequences initiated by turns beginning with ‘et là’ and locating a new referent in the environment, either in informings or in questions. While the former are frequently produced by the guide, assuming a knowing status, and the latter by the guided, assuming a not knowing, it is possible to observe informings initiated by the guided, who, by so doing, claims a revision of his or her epistemic authority. Likewise, in second position, questions are generally answered by the guide, but can also be answered by another person, claiming alternative epistemic rights. By examining the details of turn and action design in these environments, the article shows how they either reproduce and confirm the current epistemic status of the participants or challenge, negotiate and transform them. The latter case is particularly revealing of the fact that epistemic status and stance are constantly reflexively elaborated by the participants in social interaction. (shrink)

DNA replication stress threatens ordinary DNA synthesis. The evolutionarily conserved DNA replication stress response pathway involves sensor kinase Mec1/ATR, adaptor protein Mrc1/Claspin, and effector kinase Rad53/Chk1, which spurs a host of changes to stabilize replication forks and maintain genome integrity. DNA replication forks consist of largely distinct sets of proteins at leading and lagging strands that function autonomously in DNA synthesis in vitro. In this article, we discuss eSPAN and BrdU‐IP‐ssSeq, strand‐specific sequencing technologies that permit analysis of protein localization and (...) DNA synthesis at individual strands in budding yeast. Using these approaches, we show that under replication stress Rad53 stalls DNA synthesis on both leading and lagging strands. On lagging strands, it stimulates PCNA unloading, and on leading strands, it attenuates the replication function of Mrc1‐Tof1. We propose that in doing so, Rad53 couples leading and lagging strand DNA synthesis during replication stress, thereby preventing the emergence of harmful ssDNA. (shrink)

This article addresses the issue of how team identity is constructed between two people during a series of regular meetings of a work group in Serbia. Using conversation analysis to investigate social actions, this study looks at the recurrent construction of an implicit team identity by focusing on management of speaking rights and co-construction of units, and displays of knowledge and accountability. With its longitudinal perspective, the article contributes to the existing body of research on teams in interaction in general, (...) as it builds upon previous research on interactional parties and conjoined participation. The results are especially relevant for the investigations of teams in meetings, as they provide evidence of how formal features of interaction are recurrently employed to display institutionally relevant epistemics and accountability.

In this paper we introduce and compare four different syntactic methods for generating sequent calculi for the main systems of modal logic: the multiple sequents method, the higher-arity sequents method, the tree-hypersequents method and the display method. More precisely we show how the first three methods can all be translated in the fourth one. This result sheds new light on these generalisations of the sequent calculus and raises issues that will be examined in the last section.

Group musical performance, especially large instrumental ensembles, present the outward appearance of an asymmetric, temporally immediate stimulus-response relationship between conductor and ensemble. Interestingly, anecdotal reports from both conductors and performers indicate a degree of variability in the timing of orchestral response to the conductor’s gestures. This observation is not present in anecdotal accounts of other instrumental ensemble settings, like wind bands, but commonplace occurrence among orchestral musicians indicates the potential presence of greater complexity in the observed relationship. This study investigates (...) both the quality and quantity of temporal lag between conductor and ensemble in two common instrumental ensemble configurations – wind bands and orchestras – in an effort to describe the interplay present within conducted group performance. The findings indicate that the anecdotally identified lag is present within all ensemble types, and that it presents a flexible, dynamic temporal relationship between conductor and ensemble. Additionally, both the quantity and quality of lag values are significantly different between ensemble types, experience levels, and musical content. Several avenues for future research are identified, and confounds within the sampled ensembles are examined for their potential roles in the observed relationships. (shrink)

The display of artefacts always implies an external mediation that influences, and often codifies, the reception of the exhibits. Objects are manipulated, restored, appropriated, staged, in short displayed, through various representational strategies that include pedestals, labels, and showcases. These elements, that we could define as parerga, are often ignored because of their utilitarian function. Yet, they play an important role in the history of the artefacts and define the setting in which the objects can exert their agency. They not (...) only shape their meaning, but also determine the effect that these artefacts have on their viewers. Framing devices create the conditions for interactions between the individual and the object to take place. This publication aims to explore the relation between artefacts and viewers as they are manifested in framing devices, and to develop a new theoretical framework for thinking about the power of objects on display.

Live streaming shopping, the streaming of real-time videos promoting products that consumers can purchase online, has recently been a booming area of e-commerce, especially during the COVID-19 pandemic. The success of live streaming e-commerce largely relies on the extent to which the broadcaster can get consumers engaged by the live stream. Thus, it is important to discover the antecedents of consumer engagement in such a context. Drawing on consumer engagement and neuroscience literature, this study used electroencephalography inter-subject correlation to explore (...) how broadcasters' entrepreneurial passion during live streaming videos influenced consumers' neural engagement as they watched the live streaming videos. We used the framework of displayed passion and preparedness from the entrepreneurial passion literature to predict consumer engagement. We found significant ISC for strong displayed passion, while preparedness had partially significant effects on the first, second, and summed components of ISC. The interaction effects of these two factors on the first and summed components of ISC were partially significant. Strong displayed passion and preparedness activated the left and right prefrontal regions of the consumers' brains. These findings indicate that broadcasters' displayed passion and preparedness can influence consumer engagement in live streaming e-commerce settings. Our findings suggest that a scientific approach could be used to improve a broadcaster's performance by testing ISC during rehearsals before live streaming. (shrink)

In addition to proving the completeness of this list, I offer a discussion of the basic properties of these schemes.

This study investigates moments in which one participant in an interaction embodies that he is “doing thinking,” a display that is commonly referred to as “thinking face. ” From an interactional perspective, it is assumed that embodied displays of “doing thinking” are a recurring social practice and serve interactive functions. While previous studies have examined thinking faces primarily in word searches and storytelling, the present study focuses on argumentative activities, in which children engage in processes of joint decision-making. The (...) paper has two interrelated aims. The first aim is to describe how multiple modalities—beyond the face—are temporally coordinated to create multimodal gestalts of “doing thinking.” It is shown that thinking displays not only involve dynamic imaginative gaze but also stylized bodily postures. The second aim is to generate knowledge about the functions of thinking displays in children's argumentative activities. The analysis describes how both speakers and recipients use thinking displays in different turn positions and align them with verbal talk or silence. The data for this study comprise video recordings of decision-making processes in groups of older children. Drawing on a multimodal approach to situated interaction, it will be proposed that embodied displays of “doing thinking” provide a resource to shape participation frameworks, mark epistemic stances and create epistemic ecologies for collaborative reasoning. By investigating thinking displays in a particular conversational activity, the study sheds light on the diversity and context-sensitive functionality of thinking displays. It also contributes to recent research on children's collaborative reasoning as an embodied discursive practice. (shrink)

The first priority of this response is to address Libet's rebuttal of my reinterpretation of his data. Then, because many authors have commented on various aspects of the debate, the rest of the response is organized in terms of subject matter, not as replies to each individual commentator. First, I reply to an objection expressed by two separate commentators to part of my reinterpretation of those of Libet's data supposedly supporting backward referral. This leads to a brief discussion of the (...) whole concept of backward referral. The relevance of the flash-lag illusion to possible measurement errors in the Libet/Trevena and Miller paradigm is addressed next. Finally, I have a few words to say on the relationship between quantum mechanical ontology and free will. (shrink)

This paper is an attempt to think through paranoia’s epistemic and affective features, which pervade both the worldview presented in Senecan tragedy and the inner life of many of its protagonists. Drawing upon recent literary-critical work, I argue that paranoia is temporally and epistemically ambivalent: subjects simultaneously attempt to “get ahead” of a looming cataclysm—looking to the future in an attempt to avert disaster—while inevitably “falling behind,” failing to predict or preempt the future in time to protect themselves. Much of (...) Senecan tragedy plays out paranoia’s future-oriented vigilance on the formal level. Foreshadowing, allusions, and meta-literary flourishes serve to render both readers and characters hyperaware of the earth-shattering horrors to come; however, in doing so, they also reveal that this forward-oriented bracing only serves to dredge up negative affect in advance. By contrast, I argue that Seneca’s Phoenissae thematizes in the character of Oedipus not only paranoia’s future-looking vigilance but also its inherent lagging, the failure to know and act in advance. These elements of slowness, stuckness, and delay open a space for stillness, relief, and intimacy, even within a narrative which hurtles toward cataclysm. (shrink)

The time-lag argument forces us to acknowledge that all perception is perception of the past. While the spatial distance between the perceiver and the perceived typically is obvious, the temporal distance usually remains hidden from the perceiver. This temporal distance provides interesting challenges for Perceptual Realism. If objects and events in the world are presented to us as simultaneous with the experience, then the experience is illusory. If we deny that the past exists, then all perception is, like hallucination, perception (...) of something which does not exist. This chapter argues that there are, in fact, several time-lag arguments, and that their importance for philosophical theories of perception has been underestimated. It is argued that they provide important means of evaluating recent theories about perception. (shrink)
