The renewed interest in the foundations of quantum statistical mechanics in recent years has led us to study John von Neumann’s 1929 article on the quantum ergodic theorem. We have found this almost forgotten article, which until now has been available only in German, to be a treasure chest, and to be much misunderstood. In it, von Neumann studied the long-time behavior of macroscopic quantum systems. While one of the two theorems announced in his title, the one he (...) calls the “quantum H-theorem,” is actually a much weaker statement than Boltzmann’s classical H-theorem, the other theorem, which he calls the “quantum ergodic theorem,” is a beautiful and very non-trivial result. It expresses a fact we call “normal typicality” and can be summarized as follows: For a “typical” finite family of commuting macroscopic observables, every initial wave function ψ0 from a micro-canonical energy shell so evolves that for most times t in the long run, the joint probability distribution of these observables obtained from ψt is close to their micro-canonical distribution.

We explore in this study whether, how, and when time pressure leads to abusive supervisory behavior. Based on the attentional focus model, we propose that time pressure impairs supervisors’ moral awareness, which increases their subsequent abusive supervisory behavior. We also propose that the trait mindfulness of supervisors mitigates the indirect effect of time pressure on abusive supervisory behavior through moral awareness. Based on an experiment conducted by using eye-tracking methods, Study 1 tests and provides (...) support for the relationships between time pressure and moral awareness (N = 53). In Study 2, we test our full theoretical model through an experience sampling methodology for 10 workdays with data from 61 supervisors and their subordinates. Results revealed that time pressure had an indirect and positive effect on abusive supervisory behavior through the supervisors’ moral awareness. Such an indirect effect was stronger when the trait mindfulness of the supervisors was low rather than high. We conclude this research by discussing the theoretical and practical implications of our findings as well as future research directions. (shrink)

This paper takes as its starting point an examination of the current status of some of the concerns that were raised in the mid?1980s about methodological problems faced by educational researchers using the behavioural approach in schools. These concerns included the measurement of agreement between observers, the interpretation of raw data extracted, the potential influences of observers and the inherent properties of research designs. Subsequently, some more wide?ranging concerns are considered, in particular the kinds of behaviour selected for treatment, the (...) lack of analysis of what is involved in teachers? positive responses to pupils? behaviour and the relatively uninvestigated effects of teachers? negative responses. The conclusions are presented as a series of points that are listed, as far as possible, in the order in which they confront the investigator. (shrink)

A study of the organization of obsessive-compulsive disorder (OCD) rituals in time and space illuminates a postulated mechanism on shifting focus in action parsing, from mid-ranged actions to finer movements (gestures). Performance of OCD rituals also involves high concentration rather than the automated, less attended performance of rituals in normal and stereotyped behaviors in animals and humans.

BackgroundResearchers are working to identify dynamic factors involved in the shift from behavioral initiation to maintenance—factors which may depend on behavioral complexity. We test hypotheses regarding changes in factors involved in behavioral initiation and maintenance and their relationships to behavioral frequency over time, for a simple vs. complex behavior.MethodsData are secondary analyses from a larger RCT, in which young adult women, new to both behaviors, were randomly assigned to take daily calcium or to go for a daily, brisk (...) walk, for 4-weeks. Factors were measured weekly. Multi-level modeling evaluated their change over time. Bivariate correlations and multiple regression determined the relationships between factors and the subsequent-week behavioral frequency.FindingResults were partly in-line with expectations, in that individuals’ intentions and self-efficacy predicted initial behavioral engagement for both behaviors, and habit strength increased for both behaviors, becoming a significant predictor of behavioral frequency in later weeks of the study in some analyses. However, results depended on whether the outcome was self-reported or objectively measured and whether analyses were bivariate or multivariate.DiscussionThe factors theorized to play a role in behavioral maintenance started to develop, but only habit strength predicted behavioral frequency by study-end, for both behaviors. Differences in initiation and maintenance between behaviors of differing complexity may not be as stark as theorized, but longer follow-up times are required to evaluate maintenance factors.

Time pressure has been shown to have a negative impact on ethical decision-making. This paper uses an experimental approach to examine the impact of an antecedent of time pressure, whether it is anticipated or not, on participants’ perceptions of unethical behaviour. Utilising 60 business school students at an Australian university, we examine the differential impact of anticipated and unanticipated time deadline pressure on participants’ perceptions of the likelihood of unethical behaviour occurring. We find the perception of the (...) likelihood of unethical behaviour occurring to be significantly reduced when time pressure is anticipated rather than unanticipated. The implications of this finding for both professional service organisations and tertiary institutions are considered. (shrink)

I am a behavioral economist, who is interested in both behavioral sciences and economic behavior. By the term “economic behavior” I refer to the calculative reasoned domain of economic analysis, whereas by “behavioral economics” I address aspects of human feelings, emotions and everything that is not captured by the “rational” paradigm. Evidently, erroneous calculations, as well as unhinged sentiments lead to economic losses, and every change in the economics of the world has both calculative and behavioral sides to (...) it. In what follows, we examine these two sides of behavior in relation to the COVID-19 pandemic by drawing on contemporaneous data, forecasts, and images. Each side of behavior reveals distinctive insights, and intriguingly, not all outcomes count as loss. As we face this crisis, there is a clear environmental gain that we would be smart to preserve post pandemic. (shrink)

In an approach to quantify the locomotor response to environmental stimuli in fishes and its central control mechanisms, initially stochastic models of spontaneous locomotor behavior are being formulated. In the present paper, the locomotor patterns of three active nurse shark,Ginglymostoma cirratum, in six experiments are converted into 17 locomotor variables and found to have definite time series structure. Sixty-seven of the 102 first order serial correlation coefficients are statistically significant, the incidence rate of which differs between experiments and (...) between locomotor variables. The percent residual variation about an autoregressive equation is transformed by a Fisher's z statistic and the means are found to differ significantly among experiments and among variables. The experiment by variable interaction is very low implying a consistency in the ranks of the variables despite the wide differences in their absolute levels over the experiments. This suggests the existence of a relatively rigid albeit occasionally latent locomotor control mechanism in the central nervous system. (shrink)

Baumard's thesis that the English Industrial Revolution can be explained by Life History Theory's predictions for psychological development is a progression of much literature in economic and social history. However, the theory suffers from its reliance on increasingly fragile data indicators for “wealth” and its focus on “innovation” as new research begins to explore sectoral dynamics in long run growth.

Physical activity and sedentary behaviour have been linked to the mental health of children and adolescents, yet the timing of behaviours may play a role in this relationship and clarifying this could inform interventions. We explored cross-sectional associations of PA and SED in varying time segments throughout the school day with the mental health of school-aged children and adolescents from rural Northeastern Ontario, Canada. A total of 161 students wore accelerometers for 8 days and completed a self-report survey. Mental (...) health was measured using the Strengths and Difficulties Questionnaire. Accelerometer-measured SED, light PA, and moderate and vigorous PA were estimated in the time-segments before school, school time, after school, and evenings. Associations were tested with multilevel linear regressions while adjusting for confounding factors. Students spent 72.6 min in MVPA, 209.0 min in LPA, and 621.0 min in SED per day. Daily SED was associated with less conduct problems. Evening LPA was inversely associated with hyperactivity, while SED was associated with hyperactivity and with peer problems before school, and during school. No associations were observed for MVPA, emotional symptoms, or prosocial behaviour. In conclusion, displacing SED with LPA in some specific periods of the day may benefit the mental health of students; taking this into account could strengthen interventions. (shrink)

The concept of behavioural mass provides one avenue for justifying (or making rational) the phenomenon of declining impatience, according to which decision makers put more value on delays that will occur in the near future than on those that will occur later.

Although a large number of literatures have explored the relationship between electronic communication during nonwork time and individual perception and behavior under the Western culture background, we still have some limitations on this topic under the cultural background of collectivism, dedication and “Guanxi” in China. Different from Western organizations, Chinese employees tend to put work first and are more inclusive of handling work tasks during nonwork time. This type of communication during nonwork time can significantly affect (...) employees’ cognition, emotion and behavior. From the perspective of Job Demands-Resources theory, this study constructs a double-edged model between electronic communication during nonwork time and employee withdrawal behavior. Sample data were collected from 516 employees with clear working time boundaries in China. The results indicate that electronic communication during nonwork time has a U-shaped effect on employee withdrawal behavior and an inverted U-shaped effect on employee’s cognition, namely job engagement. Job engagement plays a mediating role between them. Moreover, regulatory emotional self-efficacy has a moderating effect on the relationship between electronic communication during nonwork time and job engagement. These findings not only provide theoretical and practical implications for managers and employees on how to reduce withdrawal behaviors, but also advance our understanding of electronic communication during nonwork time in Chinese cultural context.

Previous studies on whether punishers are rewarded by reputational gains have yielded conflicting results. Some studies have argued that punitive behaviors potentially result in a positive evaluation, while others have found the opposite. This study aims to clarify the conditions that lead to the positive evaluation of costly punishment. Study 1 utilized one-round and repeated public goods game situations and manipulated decision time for participants’ punitive behavior toward the non-cooperative person in the situation. We also asked participants to (...) report their impression evaluations of punitive behavior toward non-cooperative people. Moreover, utilizing the second- and third-party punishment games, Study 2 manipulated the decision time of participants’ punitive behavior toward the self-interested person and asked them to evaluate the punitive behavior. The results showed that those who punished intuitively were not likely to be evaluated positively. However, punishers were rewarded when the decision to punish was made after deliberation or made by those who were not direct victims. These findings extend previous research on the evaluation of punitive behavior and reveal that deliberative punishment is evaluated positively occasionally. (shrink)

The life we considered normal was disrupted due to measures taken to limit the spread of the novel coronavirus. Quarantine, isolation, social distancing, and community containment have influenced consumer behavior and contributed to the rapid development of e-commerce. In pandemic times, even those unfamiliar with the online environment have had to adapt and make acquisitions in this new manner. Hence, we focused our research on measuring the perception of consumers on how the restrictive measures imposed to limit the spread (...) of the COVID-19 virus had influenced their decision to buy a product or service from the online environment, given that purchases are highly subjective and influenced by cumulative effects of economic, social, psychological and behavioral factors. Our paper comes with additional insights from the literature. It adds empirical evidence that reveals that the number of transactions and the value per transaction increased during the COVID-19 pandemic and highlights that online purchases will continue as such even after the pandemic.

It is a well-documented phenomenon that individuals stop searching earlier than predicted by the optimal, risk-neutral stopping rule, leading to inefficient searches. Individuals' search behaviors during making investment decisions in financial markets can be easily affected by their peers. In this study, we designed a search game in a simplified experimental stock market in which subjects were required to search for the best sell prices for their stocks. By randomly assigning subjects into pairs and presenting them with real-time information (...) on their peers' searches, we investigated the effects of peers' decisions on search behaviors. The results showed that two subjects in the same group with real-time peer information learned and engaged in similar search behaviors. However, this peer effect did not exist when subjects had access to feedback information on the ex-post best response. In addition, we found that the presence of information about peers' decisions alone had no significant impact on search efficiency, whereas access to both information on peers' decisions and feedback information significantly improved subjects' search efficiency.

We advocate for an integrative long-term perspective on time, noting that culture changes on timescales amenable to behavioral genetic study with appropriate design and modeling extensions. We note the need for replications of behavioral genetic studies to examine model invariance across long-term timescales, which would afford examination of specified as well as unspecified cultural moderators of behavioral genetic effects.

A variety of theoretical frameworks predict the resemblance of behaviors between two people engaged in communication, in the form of coordination, mimicry, or alignment. However, little is known about the time course of the behavior matching, even though there is evidence that dyads synchronize oscillatory motions (e.g., postural sway). This study examined the temporal structure of nonoscillatory actions—language, facial, and gestural behaviors—produced during a route communication task. The focus was the temporal relationship between matching behaviors in the interlocutors (...) (e.g., facial behavior in one interlocutor vs. the same facial behavior in the other interlocutor). Cross-recurrence analysis revealed that within each category tested (language, facial, gestural), interlocutors synchronized matching behaviors, at temporal lags short enough to provide imitation of one interlocutor by the other, from one conversational turn to the next. Both social and cognitive variables predicted the degree of temporal organization. These findings suggest that the temporal structure of matching behaviors provides low-level and low-cost resources for human interaction. (shrink)

What are the distributive implications of utilitarianism? Is it compatible with a concern for equality, as many utilitarians have argued? We analyse these questions in the context of a pure allocation problem. We consider an infinitely-lived economy and, drawing on the behavioural literature, assume that individuals have reference-dependent preferences: agents’ utility is a function of current consumption and a reference point which captures consumption habits, or the agents’ upbringing. Assuming a history of inequalities in consumption, we show that the utilitarian (...) allocation is equalising: starting from an unequal distribution, inequalities decrease over time at the utilitarian optimum. However, even though agents are in a relevant sense identical, equality does not obtain at any finite time. (shrink)

The era of sustainable transformation has witnessed an increase in corporate environmental, social, and governance (ESG) disclosure waves. Using Chinese A-share listed companies from 2016 to 2021 as a sample, this study adopted textual analysis and machine-learning techniques to analyze ESG reports and explore the imitation behavior of ESG disclosures in emerging Chinese markets for the first time. The results show imitation behavior exists in corporate ESG disclosures from the perspective of group association. Regarding the imitation object, (...) enterprises tend to choose the peer average level as a reference rather than the best enterprise in the same industry, which reveals the inherent law that enterprises' ESG disclosures are satisfied with compliance rather than championship. In terms of effects, the ESG-mimetic isomorphic pressure has no incremental information effect but has an efficiency optimization effect. Furthermore, the imitation intensity and impact effects of ESG disclosure behavior exhibit heterogeneity owing to differences in properties, sales growth rates, and external attention. This study expands the motivation for corporate ESG disclosure behavior and enriches the empirical evidence for institutional isomorphism. (shrink)

This study examined how social media marketing activities influence consumers’ engagement behaviour in developing countries. Based on the stimulus-organism-response theory, we examined the effect of SMMA on consumers’ engagement intention and further investigated the moderating effect of social media sales intensity. The study employed a time-lagged design with two waves to confirm the hypothesised framework. The study findings showed that SMMA positively influence consumers’ engagement intention and engagement behaviour. In addition, social media sales intensity strengthens the link between engagement (...) intention and engagement behaviour. This study adds to the literature on social media and discusses its practical implications. (shrink)

Abstract‘Behavioural modernity’ isn’t what it used to be. Once conceived as an integrated package of traits demarcated by a clear archaeological signal in a specific time and place, it is now disparate, archaeologically equivocal, and temporally and spatially spread. In this paper we trace behavioural modernity’s empirical and theoretical developments over the last three decades, as surprising discoveries in the material record, as well the reappraisal of old evidence, drove increasingly sophisticated demographic, social and cultural models of behavioural modernity. (...) We argue, however, that some approaches to identifying and categorizing modernity have not kept up with this new picture. This is due to what we term ‘Rubicon expectations’: classificatory and interpretive practices which look for or assume clear demarcations in behavioural and cultural processes. We develop a philosophical account of ‘investigative disintegration’ to capture how our understanding of behavioural modernity has changed, and how Rubicon-based practices have become inadequate. Disintegration, in the form we analyse, occurs when scientists’ conception of a phenomenon shifts sufficiently to reshape an investigation’s epistemic structure. For behavioural modernity, the explanatory weight which once lay on identifying ‘switch-points’ in the innate suite of hominin cognitive capacities, lies now in understanding the social and demographic environments that were capable of sustaining and nourishing more complex material cultures. Finally, we argue that the phenomenon itself has not disintegrated to the point that we are left with no interesting explanandum: for all its mosaic, disparate nature, there are still good reasons for behavioural modernity to retain its central place in investigation of our species' origins.

This thesis presents a novel theory of temporal experience. While time as measured by the clock is a perennially popular topic, the time of experience remains relatively neglected and poorly understood despite its centrality to our existence. This thesis therefore sets out to address the following questions: 1) How should we characterize experiential time and the experienced present? 2) How might such distinctively temporal experience arise in the first place? While the first of these is a “what (...) is it like” question, and thus in the realm of phenomenological analysis, the second is ostensibly closer to the realm of scientific inquiry in that it concerns an empirical phenomenon. The goal of this thesis is to synthesize plausible answers to both of these questions. As to the first question, there is already a lively debate ongoing in the philosophy of mind between various camps, each offering what they see as the most plausible analysis of the phenomenology of time. Regarding the second, there is an interdisciplinary investigation of mechanisms at various levels of abstraction, notably the levels of neurophysiology and information processing. This thesis proposes, among other contentions, that the time of experience is best characterized by a combination of retentional and extensional phenomenological analyses. This means the actual temporal extension of experience and its correlates determines, to some degree, the felt temporal character of experience. At the same time, perhaps the greater part of temporal phenomenology is determined by content: mental processes can be about temporal properties in addition to their primary contents and the way they are so partially determines the temporal character of experience as well. This analysis dovetails nicely with contemporary theories of consciousness that maintain the brain is fundamentally a complex predictive engine actively and adaptively guiding behavior. The thesis thus represents a multi-level framework for understanding the experience of time and the mechanisms underpinning it. It is my hope this perspective advances the debate on time-consciousness and can guide further work towards understanding this most fundamental aspect of our lives. (shrink)

In this paper, the authors have detected a new effect in the area of geomagnetism, related to the behavior of a magnetic dipole freely floating on water surface. An experiment is described in the present paper in which a magnetic dipole fixed upon a float placed on non- magnetized water surface undergoes displacement along with reorientation caused by fine structure of the earth's magnetic field. This fact can probably be explained by secular decrease of the earth's major dipole moment. (...) Further, a detailed study of the phenomenon may create interesting premises for its practical use, particularly for the analysis of fine structure of geomagnetic field and its time-dependent anomalies. A strange behavior of some sea fish species prior to strong earthquakes may be explained if the fish are assumed as 'live magnetic dipoles'. (shrink)

Values, which serve as fundamental motivators for attitudes and behaviours, have been extensively studied in social sciences. Scholars, beginning with Allport and Rokeach, have developed various theories and conducted empirical research to examine values as independent variables and their connections to other concepts. This article provides a comprehensive review of empirical studies utilizing Schwartz’s value model and corresponding measurement scales (Schwartz Value Scale, 1992 and Portrait Value Questionnaire, 2003) to analyse the relationships between basic human values, attitudes and behaviours. Additionally, (...) we summarize the conditions under which an individual’s internal values activate and how they influence their actions. The analysis of the included articles concludes that basic human values, directly and indirectly, impact attitudes and behaviours regardless of the analytical approaches and contextual factors. Furthermore, the study found that the researchers observe these effects by considering a comprehensive value perspective, context, situational pressures or limitations, cognitive support, time and specific individual and national-level variables.

The Hadza foragers of Tanzania are currently experiencing a nutritional shift that includes the intensification of domesticated cultigens in the diet. Despite these changes, no study, to date, has examined the possible effects of this transition on the food collection behavior of young foragers. Here we present a cross-sectional study on foraging behavior taken from two time points, 2005 and 2017. We compare the number of days foraged and the type and amount of food collected for young (...) foragers, aged 5–14 years, in age- and season-matched samples. Compared with 2005, in 2017 fewer subadults left camp to forage, and overall, they targeted a smaller variety of wild foods, with the noticeable absence of wild honey, figs, and tubers. In addition, participants in 2017 were significantly more likely to have attended school. Despite the increased presence of domesticated plant foods in the diet and increased attendance at school, some young foragers continue to be highly productive in collecting wild, undomesticated foods. Despite the preliminary nature of our results, our findings suggest that the range of wild foods targeted by subadults is decreasing as the amount of domesticated cultigens in the diet increases. These data underscore the importance of studying diet composition and foraging decisions across temporal, nutritional, and ecological landscapes. (shrink)
