In the present study, we examine the process through which abusive supervision impacts employee creativity. Specifically, we test whether abusive supervision is associated with lower levels of employee creativity and if this effect is mediated by employee sleep deprivation and emotional exhaustion. Results showed that abusive supervision had an indirect negative relationship with employee creativity via its impact on employee sleep deprivation and emotional exhaustion. These findings contribute to a better understanding of the (...) negative effects of abusive supervision on employee creativity and the processes by which they occur. (shrink)

We examine whether mindfulness can neutralize the negative impact of COVID-19 stressors on employees’ sleep duration and work engagement. In Study 1, we conducted a field experiment in Wuhan, China during the lockdown between February 20, 2020, and March 2, 2020, in which we induced state mindfulness by randomly assigning participants to either a daily mindfulness practice or a daily mind-wandering practice. Results showed that the sleep duration of participants in the mindfulness condition, compared with the control condition, (...) was less impacted by COVID-19 stressors (i.e., the increase of infections in the community). In Study 2, in a 10-day daily diary study in the United Kingdom between June 8, 2020, and June 19, 2020, we replicate our results from Study 1 using a subjective measure of COVID-19 stressors and a daily measure of state mindfulness. In addition, we find that mindfulness buffers the negative effect of COVID-19 stressors on work engagement mediated by sleep duration. As the COVID-19 pandemic is ongoing and the number of reported cases continues to rise globally, our findings suggest that mindfulness is an evidence-based practice that can effectively neutralize the negative effect of COVID-19 stressors on sleep and work outcomes. The findings of the present study contribute to the employee stress and well-being literature as well as the emerging organizational research on mindfulness. (shrink)

Recent studies have highlighted the relevance of sleep for procrastination at work. Procrastination at work is defined as the irrational delay of the initiation or completion of work-related activities. In line with recent studies, we offer a self-regulation perspective on procrastination. We argue that procrastination is an outcome of depleted self-regulatory resources and that the restoration of self-regulatory resources during high-quality sleep at night would prevent procrastination.AimsIn an attempt to further develop this line of research, the current study (...) aimed to achieve a broader understanding of the relevance of sleep and circadian rhythm for procrastination. Therefore, we explored the effect of sleep quality on procrastination for different chronotypes. We also considered the shift to daylight saving time as a phenomenon that aggravates circadian misalignment and thereby later chronotypes' dependence on high-quality sleep. Specifically, we hypothesized that compared to employees with an earlier chronotype, employees with a later chronotype are more dependent on good sleep at night to prevent procrastination the next day. This effect would be especially pronounced after the shift to daylight saving time.MethodsFor this repeated-measures study, participants were 101 full-time employees. They completed a general questionnaire and day-specific questionnaires on the Monday before and the Monday following the shift to daylight saving time.ResultsThe multilevel analyses showed that employees procrastinated less on days following nights during which they slept better and that later chronotypes experienced more procrastination than earlier chronotypes. Our findings also supported the hypothesis that the relationship between sleep quality and procrastination is stronger for later chronotypes compared to earlier chronotypes on the Monday following the shift to daylight saving time. In other words, the lower the sleep quality of later chronotypes during the previous night, the more they procrastinated on the Monday following the shift to daylight saving time.DiscussionOur findings further corroborate the existing findings on the relevance of sleep and chronotype for well-being and performance at work.

Extant research suggests that workplace ostracism has a detrimental impact on the outcomes of employees. However, very little is known about the impact of workplace ostracism on sleep quality. Therefore, this study aimed to address this gap in the literature. By employing the extended stressor-detachment model, we investigated the mediating role of psychological detachment and the moderating role of coping humor. We used a self-report questionnaire and a time-lagged research design to assess employees’ workplace ostracism, coping humor, psychological detachment, (...) and sleep quality. A total of 403 valid questionnaires were obtained from participants in full-time employment in China. As predicted, the results showed that workplace ostracism is negatively associated with psychological detachment, which in turn, impairs sleep quality. We further found that high levels of coping humor buffer the negative effect of workplace ostracism on psychological detachment and sleep quality. In addition, the moderation effect of coping humor on the relationship between workplace ostracism and sleep quality is mediated by psychological detachment. Finally, based upon the results, we discuss the theoretical implications, provide practical proposals for managers and policymakers, and make suggestions for the direction of further research. Keywords: workplace ostracism, coping humor, psychological detachment, sleep quality, mediated moderation model. (shrink)

Objective: Work stress is one of the urgent public health problems, which has aroused wide attention. In addition, work stress also has a negative impact on the development of enterprises. This study has three purposes: to understand the current status of working stress among couriers, to examine the association between work stress, job satisfaction and sleep quality of Chinese couriers, and to verify the mediating role of psychological capital.Methods: A cross-sectional survey was conducted among 3000 couriers in Beijing of (...) China from January to December 2019 using cluster stratified random sampling. Descriptive statistical analysis was used to describe demographic characteristics of respondents. Pearson correlation analysis was used to analyze the correlation among work stress, job satisfaction, sleep quality, and psychological capital. The mediating analysis was calculated role of psychological capital.Results: A total of 2831 participants were included in this study. The average score of work stress was 2.49 ± 0.76. Work stress was negatively correlated with job satisfaction, sleep quality, and psychological capital, respectively. The direct effect of work stress on job satisfaction is –0.223, and the total effect of work stress on job satisfaction is –0.267. The a*b*c’ is positive, indicating the mediating role psychological capital has in explaining the relationship between couriers’ work stress and job satisfaction. Moreover, psychological capital plays a mediating role between work stress and sleep quality among couriers.Conclusion: Couriers face certain work stress and should be paid attention to and psychological capital can effectively alleviate the work stress of couriers, so measures can be taken to improve it, promoting healthy development of employees and organizations.

While previous studies have examined the negative effects of work-related smartphone use after hours, little is known about whether and how it influences employees’ unhealthy sleep behavior. Drawing on the ego depletion theory, this study explored the effects of work-related smartphone use after hours on bedtime procrastination. To further uncover potential cross-cultural differences, a sample of 210 public employees from the United States and 205 public employees from China were used. Results via path analysis revealed that off-time work-related smartphone (...) use positively influenced bedtime procrastination via the mediating role of self-control depletion. These findings were consistent between the United States and Chinese sample; however, off-time work-related smartphone use after hours increased the likelihood of self-control depletion more strongly in the United States than in China. The implications of our findings for both theory and practice were discussed. (shrink)

This paper examines the forms of life established through the visual governance of the Australian social security mobile app —the Express Plus Centrelink app. It is argued that the app exceeds established accounts of juridical and administrative power.

It is argued that the app creates proto-literate subjects that are required to respond to a real-time sequence (...) of images in a highly structured and circumscribed manner to become complicit in the digitalisation of their life.

Several lines of evidence show that systematic exposure to negative social acts at the workplace i.e., workplace bullying, results in symptoms of depression and anxiety among those targeted. However, little is known about the association between bullying, inflammatory genes and sleep problems. In the present study, we examined the indirect association between exposure to negative social acts and sleep through distress, as moderated by the miR-146a genotype. The study was based on a nationally representative survey of 1179 Norwegian (...) employees drawn from the Norwegian Central Employee Register by Statistics Norway. Exposure to workplace bullying was measured with the 9-item version of Negative Acts Questionnaire – Revised (NAQ-R) inventory. Seventeen items from Hopkins Symptom Checklist (HSCL-25) was used to measure distress. Insomnia was assessed with three items reflecting problems with sleep onset, maintenance of sleep and early morning awakening. Genotyping with regard to miR-146a rs2910164, previously linked to inflammatory processes, was carried out using Taqman assay. The data revealed that individuals systematically exposed to negative social acts at the workplace reported higher levels of sleep problems than non-exposed individuals. Moreover, the relationship between distress induced by exposure to negative social acts and insomnia was significantly stronger for individuals with the miR-146a GG genotype. Thus, the miR-146a genotype moderated the association between distress and insomnia among individuals exposed to negative social acts. The present report support the hypothesis that inflammation could play a role in stress-induced insomnia among individuals exposed to workplace bullying. (shrink)

This paper introduces an active–passive framework to the conceptualization and measurement of counterproductive work behavior (CWB), in order to establish a dimension that categorizes the content of behaviors within the existing interpersonally directed (CWBI) and organizationally directed (CWBO) framework. Doing so provides new insights into the relationship between workplace counterproductivity and sleep. Stressor-emotion models of CWB predict that employees engage in counterproductivity in response to workplace stressors, but extant research suggests that counterproductive behavior increases strain, including reduced sleep (...) quality. We develop a new scale for measuring CWB that differentiates active and passive behaviors and demonstrates the potential for positive intrapsychic consequences for passive CWBI. In Study 1, using five samples, we demonstrate the convergent and discriminant validity, reliability, and acceptable psychometric properties of a 19-item scale that reconceptualizes CWB into four dimensions: active CWBI, passive CWBI, active CWBO, and passive CWBO. In Study 2, using experience-sampling methodology, we found that when employees engage in active CWBO at work in the afternoon they experience reduced sleep quality that evening, whereas engaging in passive CWBI was related to increased sleep quality.

Oksana Sulaieva, MD, PhD is supported by the Loyola University Chicago–Ukrainian Catholic University Bioethics Fellowship Program, funded by the National Institutes of Health Fogarty International Center (D43TW011506).After 500 days of the unjust war initiated by the Russians, we look back to reflect on the challenges our medical laboratory faced during these early days. On the (...) morning of February 24th, we were awakened by the dreadful roar of sirens, the sound of which filled us with adrenaline and anxiety. Although our team had considered the risks of Russian military aggression and thus updated our emergency plan at the beginning of 2022, the first day of the war revealed that nobody was truly ready for the bombing, air alarms, tanks on the streets of towns and cities, violence and murders of civilians. That morning the city’s transportation system collapsed, and the flow of cars cluttered all the roads as people were trying to leave the city and escape the upcoming atrocities and death. Serious and disquieted people hurried along the streets—some people rushed to shelters, and others went to the military registration and enlistment offices to fight against Russian aggressors for the life, independence, and sovereignty of Ukraine.We hurried to work, committed to performing our duties. Our medical laboratory serves more than 750 hospitals in Ukraine. Despite fear and uncertainty, we walked to the lab, taking our children and alarm case1 with documents and essential things. Months later, people asked us why we went to the laboratory instead of leaving the city or even the country. At that moment, our [End Page 155] professional duties were an anchor linking us to each other against fear and panic. Our responsibility to provide patients and physicians with the results of blood testing, pathology, and molecular reports outweighed our fears of the war. We had to complete the testing of all the samples delivered to the laboratory to provide our customers—who include children, pregnant women, diabetic and cancer patients—with data essential for identifying accurate diagnoses and effective treatments. So we spent the first days of the war in the laboratory. At the same time, we had obligations and responsibilities to our staff as well. We had to consider how to manage our employees’ protection along with continuous laboratory services provided under endless air alarms and bombings. Many healthcare facilities in eastern regions and around Kyiv were affected by missiles or completely destroyed. Of our sixty laboratory offices around Ukraine, ten were damaged or abandoned due to occupation. Several of our fleet cars were also damaged and riddled with bullets. Many employees in the regional offices in Melitopol, Kherson, Mariupol, Chernihiv, and in suburbs of Kyiv such as Bucha and Irpin lost their homes as a result of massive military operations or occupation. Dozens of our employees joined the Ukrainian armed forces to defend civilians and fight against aggressors. Many others became volunteers, involved in blood donation, medical care for the wounded, cooking, and serving the troops. And still, we had to continue our work and protect our staff at the same time. We also helped each other by sharing our goods, medication, homes, cars, warmth, and support. Some pathologists stayed at the workplace for several days moving between pathology stations, microscopes and shelters, and sleeping on the floor but continuing to work.Our main challenge was the regular terroristic attacks on healthcare facilities situated far away from the front line, which in fact, violated international humanitarian law regarding respect for human rights during armed conflicts. During the first weeks of the war, the magnitude of military aggression, massive bombing, and air attacks undermined the healthcare system and endangered laboratory staff and patients. We prioritized protective measures. Some of our laboratory staff and facilities were evacuated from Kyiv to Lviv in western Ukraine. The partial relocation of our laboratory to Lviv was also driven by the displacement of several million Ukrainians to the western part of the country.We were able to arrange relatively safe accommodations for our laboratory employees and their families in Lviv.

In lieu of an abstract, here is a brief excerpt of the content:Diacritics 33.1 (2003) 60-79 [Access article in PDF] The Secret Power of Suggestion Scipio Sighele and the Postliberal Subject Suzanne R. Stewart-Steinberg He experiments one by one with about thirty young men. [...] Almost all of them respond immediately to his power of fascination by turning stiff throughout their bodies; their faces become contracted, terrified, sometimes cadaverous; they are at the mercy of the fascinator and follow his movements (...) like a magnet. [...] There is something pitiful, spasmodic in their features, something macabre in their gestures. [...] Donato has them all in his power, he attracts them in threes, in sixes, ten at a time, simply by rapidly staring into their eyes, even against their firm will and their obstinate efforts to resist his suggestion. [...] Donato, in the process, never speaks: he thinks, he wants and points. [...] —an eyewitness account, L'Italia (1886) Young male bodies that turn stiff despite their efforts to do otherwise—such were the events to be seen on the stage of the Teatro Scribe in Turin in 1886, events performed under the direction of "Donato" (the Belgian-born Alfred d'Hont), the new theatrical magnetizer of crowds. Enrico Morselli, one of Italy's leading psychiatrists of the period,1 assisted and himself succumbed to the fascination of Donato. In his important 1886 study on animal magnetism and hypnotic states, Morelli provided a rather positive portrait of the man. Donato, in his opinion, was not a vulgar man. First soldier, then state employee, journalist, novelist, poet, and finally student and apostle of animal magnetism, Donato had revolutionized hypnotic practice through his discovery of a phenomenon called "fascination." Donato was blessed with uncommon physical strength, quick and insistent eyes, a great agility of movement and much spirit. He had exchanged the magician's cap for the more sober tuxedo—quite appropriately, for he [End Page 60]rejects fluids, rejects the power and transmission of will; nor does he trade in somnambulist lucidity, in sight without eyes, in divination. He does not claim to have special secrets or gifts. Instead he claims that it is his quick and insistent "gaze" that produces a rapid and sudden shock to the nervous system of sensitive individuals. Where there is no "orgasm," he told me—but more accurately he should have said "predisposition"—his method does not work. [Morselli, Il magnetismo animale 281] What was then so revolutionary about Donato's method? Why were the spectacles at the Teatro Scribe perceived to be so radically new? And above all, why, as Morselli claims, did these shows come close to producing a political crisis right at the center of Europe [Magnetismo 271]?James Braid's discovery in 1842 that hypnotic sleep could be induced by the simple fixation on a luminous object had revolutionized magnetic theory and practice. Braid's was to prove an important discovery, for it made possible the shift from the putative supernatural powers of the hypnotist—based on the theory of the transmission of magnetic fluids or electric currents—to an analysis of characteristics thought to inhere in the hypnotized subject him- or herself. The real cause of hypnosis, its very effectivity, was to be found, as Morselli remarks, not in the magnetizer but in his subject [Magnetismo 32]. A rethinking, within the late-nineteenth-century literature on hypnotism, of what drives the subject, of what makes him act appears predicated then on a very peculiar form of interiority, of self-causation within the subject himself. At the end of its historical trajectory this rethinking would first result in the idea of auto-hypnosis or auto-suggestion, and then, by the beginning of the new century, it would found the psychoanalytic subject, traversed as he is by conflicting desires and topographically split between ego and superego. In both instances, however, obedience is exacted as a result of an internalized command and—and here lies the peculiarity and utter novelty of this subject—for that reason the subject ceases to be master of his own house.In the remarks that follow, I will leave aside Freud's own contributions...

A new philosophical analysis is provided of the notorious Sleeping Beauty Problem. It is argued that the correct solution is one-third, but not in the way previous philosophers have typically meant this. A modified version of the Problem demonstrates that neither self-locating information nor amnesia is relevant to the core Problem, which is simply to evaluate the conditional chance of heads given an undated Monday-or-Tuesday awakening. Previous commentators have failed to appreciate the significance of the information that Beauty gains upon (...) waking, and which is relevant to the conditional chance of heads: de re acquaintance with the awakening itself and the non-locating knowledge that it is an experimental awakening. David Lewis and company are committed to several unjustifiable and unacceptable probability assessments. Previous commentators have in effect confused the information that Beauty undergoes this particular experimental awakening for the information that she undergoes some experimental awakening or other. Lewis in particular thereby illegitimately tips the scales both in favor of heads and in favor of Monday. The Sleeping Beauty Problem is equivalent to a ball-in-urn word problem in elementary probability theory. (shrink)

Sleep and dreaming are important daily phenomena that are receiving growing attention from both the scientific and the philosophical communities. The increasingly popular predictive brain framework within cognitive science aims to give a full account of all aspects of cognition. The aim of this paper is to critically assess the theoretical advantages of Predictive Processing (PP, as proposed by Clark 2013, Clark 2016; and Hohwy 2013) in defining sleep and dreaming. After a brief introduction, we overview the state (...) of the art at the intersection between dream research and PP (with particular reference to Hobson and Friston 2012; Hobson et al. 2014). In the following sections we focus on two theoretically promising aspects of the research program. First, we consider the explanations of phenomenal consciousness during sleep (i.e. dreaming) and how it arises from the neural work of the brain. PP provides a good picture of the peculiarity of dreaming but it can’t fully address the problem of how consciousness comes to be in the first place. We propose that Integrated Information Theory (IIT) (Oizumi et al. 2014; Tononi et al. 2016) is a good candidate for this role and we will show its advantages and points of contact with PP. After introducing IIT, we deal with the evolutionary function of sleeping and dreaming. We illustrate that PP fits with contemporary researches on the important adaptive function of sleep and we discuss why IIT can account for sleep mentation (i.e. dreaming) in evolutionary terms (Albantakis et al. 2014). In the final section, we discuss two future avenues for dream research that can fruitfully adopt the perspective offered by PP: (a) the role of bodily predictions in the constitution of the sleeping brain activity and the dreaming experience, and (b) the precise role of the difference stages of sleep (REM (Rapid eye movement), NREM (Non-rapid eye movement) in the constitution and refinement of the predictive machinery.

The Sleeping Beauty problem is presented in a formalized framework which summarizes the underlying probability structure. The two rival solutions proposed by Elga and Lewis differ by a single parameter concerning her prior probability. They can be supported by considering, respectively, that Sleeping Beauty is “fuzzy-minded” and “blank-minded”, the first interpretation being more natural than the second. The traditional absent -minded driver problem is reinterpreted in this framework and sustains Elga’s solution.

This paper examines three accounts of the sleeping beauty case: an account proposed by Adam Elga, an account proposed by David Lewis, and a third account defended in this paper. It provides two reasons for preferring the third account. First, this account does a good job of capturing the temporal continuity of our beliefs, while the accounts favored by Elga and Lewis do not. Second, Elga’s and Lewis’ treatments of the sleeping beauty case lead to highly counterintuitive consequences. The proposed (...) account also leads to counterintuitive consequences, but they’re not as bad as those of Elga’s account, and no worse than those of Lewis’ account. (shrink)

Cian Dorr (2002) gives an argument for the 1/3 position in Sleeping Beauty. I argue this is based on a mistake about Sleeping Beauty's epistemic position.

Adam Elga takes the Sleeping Beauty example to provide a counter-example to Reflection, since on Sunday Beauty assigns probability 1/2 to H, and she is certain that on Monday she will assign probability 1/3. I will show that there is a natural way for Bas van Fraassen to defend Reflection in the case of Sleeping Beauty, building on van Fraassen’s treatment of forgetting. This will allow me to identify a lacuna in Elga’s argument for 1/3. I will then argue, however, (...) that not all is well with Reflection: there is a problem with van Fraassen’s treatment of forgetting. Ultimately I will agree with Elga’s 1/3 answer. David Lewis maintains that the answer is 1/2; I will argue that cases of forgetting can be used to show that the premiss of Lewis’s argument for 1/2 is false. (shrink)

The Sleeping Beauty problem is test stone for theories about self-locating belief, i.e. theories about how we should reasons when data or theories contain indexical information. Opinion on this problem is split between two camps, those who defend the "1/2 view" and those who advocate the "1/3 view". I argue that both these positions are mistaken. Instead, I propose a new "hybrid" model, which avoids the faults of the standard views while retaining their attractive properties. This model _appears_ to violate (...) Bayesian conditionalization, but I argue that this is not the case. By paying close attention to the details of conditionalization in contexts where indexical information is relevant, we discover that the hybrid model is in fact consistent with Bayesian kinematics. If the proposed model is correct, there are important lessons for the study of self-location, observation selection theory, and anthropic reasoning. (shrink)

The strong law of large numbers and considerations concerning additional information strongly suggest that Beauty upon awakening has probability 1/3 to be in a heads-awakening but should still believe the probability that the coin landed heads in the Sunday toss to be 1/2. The problem is that she is in a heads-awakening if and only if the coin landed heads. So, how can she rationally assign different probabilities or credences to propositions she knows imply each other? This is the problem (...) I address in this article. I suggest that ‘p whenever q and vice versa’ may be consistent with p and q having different probabilities if one of them refers to a sample space containing ordinary possible worlds and the other to a sample space containing centred possible worlds, because such spaces may fail to combine into one composite probability space and, as a consequence, ‘whenever’ may not be well defined; such is the main contribution of this article. 1The Sleeping Beauty Game2Groisman’s and Peter Lewis’s Approaches3Discussing Beauty’s Credences4The Principle of Equivalence's Failure5Making Sense of the Principle of Equivalence's Failure6Elga’s and Lewis’s Approaches7ConclusionAppendix.

Terence Horgan defends the thirder position on the Sleeping Beauty problem, claiming that Beauty can, upon awakening during the experiment, engage in “synchronic Bayesian updating” on her knowledge that she is awake now in order to justify a 1/3 credence in heads. In a previous paper, I objected that epistemic probabilities are equivalent to rational degrees of belief given a possible epistemic situation and so the probability of Beauty’s indexical knowledge that she is awake now is necessarily 1, precluding such (...) updating. In response, Horgan maintains that the probability claims in his argument are to be taken, not as claims about possible rational degrees of belief, but rather as claims about “quantitative degrees of evidential support.” This paper argues that the most plausible account of quantitative degree of support, when conjoined with any of the three major accounts of indexical thought in such a way as to plausibly constrain rational credence, contradicts essential elements of Horgan’s argument.

I defend the suggestion that the rational probability in the Sleeping Beauty paradox is one third. The reasoning in its favour is familiar: for every heads-waking, there are two tails-wakings. To complete the defense, I rebut the reasoning which purports to justify the competing suggestion – that the correct probability is half – by undermining its premise, that no new information has been received.

This paper examines employees’ reactions to Corporate Social Responsibility programs at the attitudinal level. The results presented are drawn from an in-depth study of two Chilean construction firms that have well-established CSR programs. Grounded theory was applied to the data prior to the construction of the conceptual framework. The analysis shows that the implementation of CSR programs generates two types of attitudes in employees: attitudes toward the organization and attitudes toward society. These two broad types of attitudes can then be (...) broken down into four different categories : acceptance of the new role of the organization, identification with the organization, importance attached to the work performed and a sense of social justice. In turn, each of these categories is a grouping of many different concepts, some of which have at first sight little to do with CSR. Finally, the analysis reveals an attitudinal employee typology: the committed worker, the indifferent worker, and the dissident worker. (shrink)

Argues for the "thirder" solution to the Sleeping Beauty puzzle. The argument turns on an analogy with a variant case, in which a coin-toss on Monday night determines whether one's memories of Monday are permanently erased, or merely suspended in such a way that they will return some time after one wakes up on Tuesday.

Currently, the most popular views about how to update de se or self-locating beliefs entail the one-third solution to the Sleeping Beauty problem.2 Another widely held view is that an agent‘s credences should be countably additive.3 In what follows, I will argue that there is a deep tension between these two positions. For the assumptions that underlie the one-third solution to the Sleeping Beauty problem entail a more general principle, which I call the Generalized Thirder Principle, and there are situations (...) in which the latter principle and the principle of Countable Additivity cannot be jointly satisfied. The most plausible response to this tension, I argue, is to accept both of these principles, and to maintain that when an agent cannot satisfy them both, she is faced with a rational dilemma.

The Sleeping Beauty paradox in epistemology and the many-worlds interpretation of quantum mechanics both raise problems concerning subjective probability assignments. Furthermore, there are striking parallels between the two cases; in both cases personal experience has a branching structure, and in both cases the agent loses herself among the branches. However, the treatment of probability is very different in the two cases, for no good reason that I can see. Suppose, then, that we adopt the same treatment of probability in each (...) case. Then the dominant ‘thirder’ solution to the Sleeping Beauty paradox becomes incompatible with the tenability of the many-worlds interpretation. (shrink)

What degrees of belief does Sleeping Beauty's evidence support? That depends.

This paper explores the meaning of dreamless sleep. First, I consider four reasons why we commonly pass over sleep's ontological significance. Second, I compare and contrast death and sleep to show how each is oriented to questions regarding the possibilities of "being-a-whole." In the third and final part, I explore the meaning and implications of "being-toward-sleep," arguing that human existence emerges atop naturally anonymous corporeality (i.e. living being). In sum, I try to show that we can (...) recover an authentic — if somewhat ambiguous — sense of "being-a-whole" only by recognizing the ontological significance of dreamless sleep. (shrink)

The traditional solutions to the Sleeping Beauty problem say that Beauty should have either a sharp 1/3 or sharp 1/2 credence that the coin flip was heads when she wakes. But Beauty’s evidence is incomplete so that it doesn’t warrant a precise credence, I claim. Instead, Beauty ought to have a properly imprecise credence when she wakes. In particular, her representor ought to assign \(R(H\!eads)=[0,1/2]\) . I show, perhaps surprisingly, that this solution can account for the many of the intuitions (...) that motivate the traditional solutions. I also offer a new objection to Elga’s restricted version of the principle of indifference, which an opponent may try to use to collapse the imprecision. (shrink)

Using an observational sample of players of a simple online game, we are able to trace the development of skill in that game. Information on playing time, and player location, allows us to estimate time of day during which practice took place. We compare those whose breaks in practice probably contained a night's sleep and those whose breaks in practice probably did not contain a night's sleep. Our analysis confirms experimental evidence showing a benefit of spacing for skill (...) learning, but it fails to find any additional benefit of sleeping during a break from practice. We discuss reasons why the well-established phenomenon of sleep consolidation might not manifest in an observational study of skill development. We put the spacing effect into the context of the other known influences on skill learning: improvement with practice, and individual differences in initial performance. Analysis of performance data from games allows experimental results to be demonstrated outside of the lab and for experimental phenomenon to be put in the context of the performance of the whole task.

A long history of research has revealed many neurophysiological changes and concomitant behavioral impacts of sleep deprivation, sleep restriction, and circadian rhythms. Little research, however, has been conducted in the area of computational cognitive modeling to understand the information processing mechanisms through which neurobehavioral factors operate to produce degradations in human performance. Our approach to understanding this relationship is to link predictions of overall cognitive functioning, or alertness, from existing biomathematical models to information processing parameters in a cognitive (...) architecture, leveraging the strengths from each to develop a more comprehensive explanation. The integration of these methodologies is used to account for changes in human performance on a sustained attention task across 88 h of total sleep deprivation. The integrated model captures changes due to time awake and circadian rhythms, and it also provides an account for underlying changes in the cognitive processes that give rise to those effects. The results show the potential for developing mechanistic accounts of how fatigue impacts cognition, and they illustrate the increased explanatory power that is possible by combining theoretical insights from multiple methodologies.

We propose that sleep is linked to synaptic homeostasis. Specifically, we propose that: (1) Wakefulness is associated with synaptic potentiation in cortical circuits; (2) synaptic potentiation is tied to the homeostatic regulation of slow wave activity; (3) slow wave activity is associated with synaptic downscaling; and (4) synaptic downscaling is tied to several beneficial effects of sleep, including performance enhancement.

The phenomenon of dreamless sleep and its philosophical consequences, particularly deep sleep's relevance to such issues as Self, Consciousness, Personal Identity, Unity of Subject, and Disembodied Life, are explored through a discussion, in varying detail, of certain noted doctrines and views--for example of Advaita Vedānta, Hegel, and H. D. Lewis. Finally, with a cue from Leibniz and McTaggart, the suggestion is made that at no stage during sleep is the self without some perceptions, however indeterminate. Support for (...) this hypothesis is claimed from the current psychoanalytic opinion that mental activity does not cease during any part of sleep and that human beings continue to dream even in the so-called dreamless state.

Campaigning activities of non-governmental organisations (NGOs) have increased public awareness and concern regarding the alleged unethical and environmentally damaging practices of many major multinational companies.

This has often involved a move towards greater transparency in company practice and a desire to engage with stakeholders, often including many of the campaign organisations that (...) have been at the forefront of the criticisms of their activity.

In doing so, it contributes to the call for more ‘stakeholder-focused’ research in this field (Frooman in Acad Manag Rev 24(2): 191–205, 1999; Steurer in Bus Strategy Environ 15: 15–69 2006). By adopting a stakeholder lens, and focusing more heavily upon the impact on one particular stakeholder community (NGOs) and looking in depth at one form of engagement (stakeholder dialogue), this article examines how experiences of dialogue are strategically transforming interactions between businesses and NGOs. It shows how experiences of stakeholder dialogue have led to transformations in the drivers for engagement, transformations in the processes of engagement and transformations in the terms of engagement. Examining these areas of transformation, the article argues, reveals the interactions at play in framing and shaping the evolving relationships between business and its stakeholders. (shrink)

Using an observational sample of players of a simple online game, we are able to trace the development of skill in that game. Information on playing time, and player location, allows us to estimate time of day during which practice took place. We compare those whose breaks in practice probably contained a night's sleep and those whose breaks in practice probably did not contain a night's sleep. Our analysis confirms experimental evidence showing a benefit of spacing for skill (...) learning, but it fails to find any additional benefit of sleeping during a break from practice. We discuss reasons why the well-established phenomenon of sleep consolidation might not manifest in an observational study of skill development. We put the spacing effect into the context of the other known influences on skill learning: improvement with practice, and individual differences in initial performance. Analysis of performance data from games allows experimental results to be demonstrated outside of the lab and for experimental phenomenon to be put in the context of the performance of the whole task.

Analyses of the Sleeping Beauty Problem are polarised between those advocating the “1/2 view” (“halfers”) and those endorsing the “1/3 view” (“thirders”). The disagreement concerns the evidential relevance of self-locating information. Unlike halfers, thirders regard self-locating information as evidentially relevant in the Sleeping Beauty Problem. In the present study, we systematically manipulate the kind of information available in different formulations of the Sleeping Beauty Problem. Our findings indicate that patterns of judgment on different formulations of the Sleeping Beauty Problem do (...) not fit either the “1/2 view” or the “1/3 view.” Human reasoners tend to acknowledge self-locating evidence as relevant, but discount its weight significantly. Accordingly, self-locating information may trigger more cautious judgments of confirmation than familiar kinds of statistical evidence. We also discuss how these results can advance the debate by providing a more nuanced and empirically grounded account or explication of the evidential impact of self-locating information. (shrink)

The employee owned company (EOC) might be the ideal blend of capitalism and communitarianism that vitalizes the global economy. EOCs – based on the concepts of employee participation and control – have sprung up in the United Kingdom, some parts of the European Union, the United States, Japan, and the former Eastern Bloc countries. Research has shown that they are able to compete effectively with more traditional companies. However, in addition to the pressures of business competition, EOCs face (...) two other key problems as they strive to survive: (1) degeneration and (2) human nature and the abuse of power. After introducing the idea of the EOC and describing briefly these two key problems, this article presents seven recommendations for sustaining employee owned companies. These recommendations – grounded in sound organizational theory and the writings of experts in the field of employee ownership – are offered as hypotheses to be examined empirically by future researchers.

The article aims to bridge divides between political theory and management and organization studies in theorizing workplace democracy. To achieve this aim, the article begins by introducing a new definition of democracy which, it is contended, is better suited than mainstream accounts to highlight the democratizing potential of employee involvement. It then defines employee involvement as an offshoot of early twentieth-century humanistic psychologies, from which it inherits an emancipatory ambition. In a third step, the article presents employee (...) involvement as a set of organizational practices liable to transform dominant patterns of authority and social interaction in the workplace. The article concludes by contending that, apart from representation/participation and the employee’s voice, employee involvement must be considered the third necessary pillar of workplace democracy, endowed with distinctive normative features that neither representation/participation nor voices can aptly capture.

This paper offers a novel interpretation of the political implications of Hobbes’s theory of imagination and his solution to the threat posed by the imagination to political stability. While recent work has correctly identified the problem the imagination poses for Hobbes, it has underestimated the severity of the problem and, accordingly, has underestimated the length to which the Hobbesian sovereign will have to go in order to solve it. By reconstructing Hobbes’s account of sleep and the operation of the (...) imagination during sleep, this paper argues that the Hobbesian sovereign who seeks to solve the problem of the imagination must maintain his subjects in a ‘state of sleep,’ by preventing any kind of new inputs from disturbing their imagination. This solution suggests that the citizens of the Leviathan state are not sleeping sovereigns, but rather sleeping subjects. (shrink)

This paper deals with new pharmacological and technological developments in the manipulation and curtailment of our sleep needs. While humans have used various methods throughout history to lengthen diurnal wakefulness, recent advances have been achieved in manipulating the architecture of the brain states involved in sleep. The progress suggests that we will gradually become able to drastically manipulate our natural sleep-wake cycle. Our goal here is to promote discussion on the desirability and acceptability of enhancing our control (...) over biological sleep, by illustrating various potential attendant ethical problems. We draw attention to the risks involved, possible conflicts of interests underlying the development of wake enhancement, and the potential impact on accountability for fatigue related errors.

I defend the suggestion that the rational probability in the Sleeping Beauty paradox is one third. The reasoning in its favour is familiar: for every heads-waking, there are two tails-wakings. To complete the defense, I rebut the reasoning which purports to justify the competing suggestion – that the correct probability is half – by undermining its premise, that no new information has been received.

In this paper, I argue for a view largely favorable to the Thirder view: when Sleeping Beauty wakes up on Monday, her credence in the coin’s landing heads is less than 1/2. Let’s call this “the Lesser view.” For my argument, I (i) criticize Strict Conditionalization as the rule for changing de se credences; (ii) develop a new rule; and (iii) defend it by Gaifman’s Expert Principle. Finally, I defend the Lesser view by making use of this new rule.

Consciousness can be studied only if subjective experience is documented and quantified, yet first-person accounts of the effects of brain injury on conscious experience are as rare as they are potentially useful. This report documents the alterations in waking, sleeping, and dreaming caused by a lateral medullary infarct. Total insomnia and the initial suppression of dreaming was followed by the gradual recovery of both functions. A visual hallucinosis during waking that was associated with the initial period of sleep and (...) dream suppression is described in detail. Since the changes in sleep and their recovery are comparable to results of animal experiments, it can be concluded that damage to the medullary brain stem causes extreme but short-lived alterations in conscious state and that substantial recovery occurs even though the damage to the brain stem endures.
