A breath of toxic air: The relationship between appraised air pollution, abusive supervision, and laissez-faire leadership through the dual-mediating pathways of negative affect and somatic complaints.

Air pollution has become a global public health hazard leading to debilitating effects on physical, mental, and emotional health. Management research has just begun to explore the effects of air pollution on employees' work life. Drawing from the transactional theory of stress (Lazarus & Folkman, 1984) and crossover theory (Westman, 2001), we argue that appraisal of air pollution is an important factor that influences leaders and their behavior with subordinates. Specifically, we propose that when leaders appraise severe air pollution, they are more likely to behave abusively toward their subordinates and engage in laissez-faire leadership. We also propose that this relationship is mediated by leaders' experience of somatic complaints and negative affect. We test our model using an experience sampling study in India of leaders and followers who were located in different cities from each other. Overall, our results highlight how air pollution appraisals can harm not only the leader experiencing the pollution but also subordinates of those leaders. In other words, our counterintuitive finding is that subordinates may be harmed by air pollution to which they are not even directly exposed.

Being robbed of an hour of sleep: The impact of the transition to Daylight Saving Time on work engagement depends on employees' chronotype.

OBJECTIVE: Worldwide, over 70 countries advance their clocks in spring to Daylight Saving Time. Previous research has already demonstrated that the clock change negatively impacts employees at work. However, this research implicitly assumed that the clock change affects everyone to the same extent. In the current study, we propose that the massively prevalent Daylight Saving Time transition may have an effect on employees' sleep and their work engagement that is dependent upon employees' chronotype. METHODS: We conducted a longitudinal study with 155 full-time employees who filled out online surveys on three Mondays around the transition to Daylight Saving Time. RESULTS: Results showed that the transition to Daylight Saving Time resulted in decreased work engagement measured 1day as well as 1week after the transition to Daylight Saving Time. Lower sleep quality (but not shorter sleep duration) partly explained this effect. The negative effect of the transition to Daylight Saving Time on work engagement 1day after the transition was more pronounced for employees with later chronotypes ("owls") than for those with earlier chronotypes ("larks"). CONCLUSION: In summary, our study shows that the transition to Daylight Saving Time has an adverse short-time impact on private life and working life and should, therefore, also be considered in organizations. Because later chronotypes are especially prone to adverse effects of the transition, interventions targeted for this group might be especially helpful.

Using wearable technology (closed loop acoustic stimulation) to improve sleep quality and work outcomes.

Drawing from the neuroscience literature and recent advancements in sleep technology, we examine how closed loop acoustic stimulation can improve employee sleep and subsequent work behaviors. Specifically, we hypothesize that because closed loop acoustic stimulation improves sleep quality, it enhances work engagement, task performance, and organizational citizenship behavior (OCB) and lowers counterproductive workplace behavior. In a 4-week within-subjects field experiment, 81 employees wore headbands during sleep hours in active mode (with closed loop acoustic stimulation) or sham mode with the volume off (control condition). We found that the treatment condition was linked to higher work engagement, task performance, and OCB the next day (but not counterproductive workplace behavior). Additionally, we found that the headbands were more effective for younger employees. This study contributes to the literature on sleep and work by highlighting a cost-efficient intervention for improving sleep and sleep-related outcomes which do not rely on surmounting the difficulties entailed in increasing sleep duration, as well as age as a boundary condition limiting the effects.

Cannabis use does not increase actual creativity but biases evaluations of creativity.

In this research, we examine the effects of cannabis use on creativity and evaluations of creativity. Drawing on both the broaden-and-build theory and the affect-as-information model, we propose that cannabis use would facilitate more creativity as well as more favorable evaluations of creativity via cannabis-induced joviality. We tested this prediction in two experiments, wherein participants were randomly assigned to either a cannabis use or cannabis abstinence condition. We find support for our prediction that cannabis use facilitates joviality, which translates to more favorable evaluations of creativity of one's own ideas and others' ideas. However, our prediction that cannabis use facilitates creativity via joviality was not supported. Our findings suggest that cannabis use may positively bias evaluations of creativity but have no impact on creativity. Implications for theory and practice are discussed.

Effect of Use of a Bougie vs Endotracheal Tube With Stylet on Successful Intubation on the First Attempt Among Critically Ill Patients Undergoing Tracheal Intubation: A Randomized Clinical Trial.

Importance: For critically ill adults undergoing emergency tracheal intubation, failure to intubate the trachea on the first attempt occurs in up to 20% of cases and is associated with severe hypoxemia and cardiac arrest. Whether using a tracheal tube introducer ("bougie") increases the likelihood of successful intubation compared with using an endotracheal tube with stylet remains uncertain. Objective: To determine the effect of use of a bougie vs an endotracheal tube with stylet on successful intubation on the first attempt. Design, Setting, and Participants: The Bougie or Stylet in Patients Undergoing Intubation Emergently (BOUGIE) trial was a multicenter, randomized clinical trial among 1102 critically ill adults undergoing tracheal intubation in 7 emergency departments and 8 intensive care units in the US between April 29, 2019, and February 14, 2021; the date of final follow-up was March 14, 2021. Interventions: Patients were randomly assigned to use of a bougie (n = 556) or use of an endotracheal tube with stylet (n = 546). Main Outcomes and Measures: The primary outcome was successful intubation on the first attempt. The secondary outcome was the incidence of severe hypoxemia, defined as a peripheral oxygen saturation less than 80%. Results: Among 1106 patients randomized, 1102 (99.6%) completed the trial and were included in the primary analysis (median age, 58 years; 41.0% women). Successful intubation on the first attempt occurred in 447 patients (80.4%) in the bougie group and 453 patients (83.0%) in the stylet group (absolute risk difference, -2.6 percentage points [95% CI, -7.3 to 2.2]; P = .27). A total of 58 patients (11.0%) in the bougie group experienced severe hypoxemia, compared with 46 patients (8.8%) in the stylet group (absolute risk difference, 2.2 percentage points [95% CI, -1.6 to 6.0]). Esophageal intubation occurred in 4 patients (0.7%) in the bougie group and 5 patients (0.9%) in the stylet group, pneumothorax was present after intubation in 14 patients (2.5%) in the bougie group and 15 patients (2.7%) in the stylet group, and injury to oral, glottic, or thoracic structures occurred in 0 patients in the bougie group and 3 patients (0.5%) in the stylet group. Conclusions and Relevance: Among critically ill adults undergoing tracheal intubation, use of a bougie did not significantly increase the incidence of successful intubation on the first attempt compared with use of an endotracheal tube with stylet.

Guiding principles for determining work shift duration and addressing the effects of work shift duration on performance, safety, and health: guidance from the American Academy of Sleep Medicine and the Sleep Research Society.

CITATION: Risks associated with fatigue that accumulates during work shifts have historically been managed through working time arrangements that specify fixed maximum durations of work shifts and minimum durations of time off. By themselves, such arrangements are not sufficient to curb risks to performance, safety, and health caused by misalignment between work schedules and the biological regulation of waking alertness and sleep. Science-based approaches for determining shift duration and mitigating associated risks, while addressing operational needs, require: (1) a recognition of the factors contributing to fatigue and fatigue-related risks; (2) an understanding of evidence-based countermeasures that may reduce fatigue and/or fatigue-related risks; and (3) an informed approach to selecting workplace-specific strategies for managing work hours. We propose a series of guiding principles to assist stakeholders with designing a shift duration decision-making process that effectively balances the need to meet operational demands with the need to manage fatigue-related risks.

A sleep and self-control model of cyber incivility at work.

OBJECTIVES: To conduct an empirical test of a conceptual model in which sleep duration would have an indirect negative effect on cyber incivility at work, mediated by self-regulatory fatigue and moderated by agreeableness. DESIGN: A 2-week daily diary study in which employees completed daily surveys in the mornings and at the end of the workday. SETTING: An observational study which measured sleep and work behaviors in the daily work lives of our participants. PARTICIPANTS: One hundred thirty-one adults who were full-time employees and were also enrolled in a 2-year Executive Post Graduate Program at a university in India. MEASUREMENT: Participants completed a baseline survey which included agreeableness as well as demographics and person-level control variables. At 7 AM each workday, we sent participants the morning survey which included the sleep measure. At 4 PM each workday, we sent participant the end of workday survey which included measures of self-regulatory fatigue, cyber incivility, and day-level control variables. Participants completed a total of 945 morning surveys and 843 afternoon surveys. RESULTS: Results supported our model. Sleep duration was negatively associated with self-regulatory fatigue, which was positively related to cyber incivility. Agreeableness moderated the relationship between sleep duration and self-regulatory fatigue, as well as the indirect effect of sleep duration on cyber incivility. CONCLUSION: Employees have more self-regulatory fatigue and thus engage in higher levels of cyber incivility at work after a shorter night of sleep, especially if those employees are low in agreeableness.

Sleep and self-control: A systematic review and meta-analysis.

Controlling impulses and overcoming temptations (i.e., self-control) are key aspects of living a productive life. There is a growing yet disperse literature indicating that sleep is an important predictor of self-control. The goal of this meta-analysis is to empirically integrate the findings from multiple literatures, and investigate whether sleep quality, and sleep duration predict self-control. To provide a thorough understanding of the proposed relationships, this meta-analysis also investigated potential differences between the level of analysis (between-individual vs. within-individual), research design (experiment vs. correlation; and cross-sectional vs. time-lagged), and types of measure (subjective vs. objective for sleep and self-control). A systematic review was conducted through ABI/Inform (including PsycInfo), ERIC, ProQuest Dissertation & Theses, PubMed, and Psychology Database using keywords related to self-control and sleep. Sixty-one independent studies met the inclusion criteria. The results, in general, suggest that sleep quality (between-individual 0.26, CI 0.21; 0.31; and within-individual 0.35, CI 0.24; 0.45), and sleep duration (between-individual 0.14, CI 0.07; 0.21; and within-individual 0.20, CI 0.09; 0.31) are all related to self-control. Given the impact of self-control on how individuals live productive lives, a future research agenda should include a deeper investigation in the causal process (potentially via prefrontal cortex activity) linking sleep and self-control, and an examination of the moderators (individual and contextual variables) that could impact the relationship between sleep and self-control.

Sleep and social relationships in healthy populations: A systematic review.

Over the past decade, research linking sleep and social relationships has burgeoned. Researchers across the globe are trying to understand whether the quality and quantity of our social relationships matter for sleep, and vice versa. We conducted a systematic review of the literature, identifying over 200 relevant articles examining sleep and social relationships in healthy populations. Here, we summarize our findings by reviewing 1) links between sleep and broad social ties across the lifespan, and 2) links between sleep and specific social relationships identified in the literature search, including romantic relationships, family relationships, and work relationships. Taken together, the literature provides evidence that the quality and presence of social relationships, especially our closest relationships, play a role in how we sleep. Likewise, sleep appears to influence our social bonds. However, the majority of work is correlational, limiting conclusions about the directionality of these effects. We conclude by synthesizing the findings, considering the limitations of the present literature, and identifying key future directions for this emerging area of research.

An attributional process model of workplace gossip.

Despite the ubiquity of gossip in the workplace, the management literature offers a limited understanding of its consequences for gossip senders. To understand whether gossiping is beneficial or detrimental for the gossip sender, it is necessary to consider the perspective of gossip recipients and their response to gossip. We develop a typology of gossip that characterizes archetypal patterns of interpreting gossip. We then draw from attribution theory to develop a multilevel process model of workplace gossip that focuses on how the gossip recipient's attributions of a gossip episode shape the gossip recipient's subsequent response and behaviors. In addition to the valence and work-relatedness dimensions of gossip that comprise the typology, we examine credibility and the status of the gossip target as fundamental features of the gossip episode that jointly affect the gossip recipient's attributions. At the episodic level, the process of deciphering the gossip sender's motives influences the subsequent reciprocation of gossip. Depending on the locus of causality attributed to the gossip episode, gossip also contributes to the perceived trustworthiness of the gossip sender and the gossip recipient's cooperation with or social undermining of the gossip sender over time. The proposed model suggests that the potential benefits or social consequences of gossip for the gossip sender depend on the characteristics of the gossip and the context of the gossip episode that serve as inputs to the gossip recipient's attributional process.

The effects of blue-light filtration on sleep and work outcomes.

In this article, we investigate the effects of blue-light filtration on broad attitudinal and behavioral outcomes (i.e. work engagement, organizational citizenship behavior, and counterproductive work behavior). Drawing on recent developments in the circadian process literature and its related research on chronobiology, we propose that a cost-effective sleep intervention can improve multiple organizationally relevant outcomes. Specifically, we theorize that wearing blue-light filtering glasses creates a form of physiologic darkness, thus improving both sleep quantity and quality. We then argue that wearing blue-light filtering glasses is related to work engagement, task performance, and nontask performance via sleep quantity and sleep quality. Considering that individuals vary in the timing of their circadian process, we propose that chronotype is a first-stage moderator for our theoretical model. We tested these theoretical expectations in 2 experimental experience sampling studies. In Study 1a, we collected data from 63 managers (519 daily observations) and found that wearing blue-light filtering glasses is an effective intervention to improve physiological (sleep), attitudinal (work engagement), and behavioral (task performance, organizational citizenship behavior, and counterproductive work behavior) outcomes. In general, the effects were stronger for employees who tend to have sleep periods later in the day. In Study 1b, we collected data from 67 call center representatives (529 daily observations) and measured task performance from clients. We replicated most of the findings except for the interactions. Our model highlights how and when wearing blue-light filtering glasses can help employees to live and work better. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

An exploration of employee dreams: The dream-based overnight carryover of emotional experiences at work.

OBJECTIVE: We sought to explore the manner in which daily challenge and hindrance stressors at work may be associated with mood the next day, through the mediating mechanisms of presleep rumination and moods experienced while asleep during dreams. METHODS: A daily diary study in which 94 adults with full-time jobs completed 2 surveys per day for 2 work weeks. Each morning, participants reported the degree to which they engaged in rumination before sleep the previous night, the affective tone of their dreams, and their mood at that moment. Each evening participants reported their experiences of challenge and hindrance stressors at work that day. RESULTS: Hindrance stressors were positively related to next-morning negative affect via the effects of rumination and negative affect in dreams. Challenge stressors negatively related to positive affect in the morning, via rumination and lowered positive affect in dreams. These results occurred above and beyond the effects of sleep quantity, sleep quality, and several other time-based control variables. CONCLUSIONS: Dreams play an important role in how work stressors which are experienced in a given workday are associated with mood the next morning.

Association of high profile football matches in Europe with traffic accidents in Asia: archival study.

OBJECTIVE: To investigate the association between popular football games played in Europe and the incidence of traffic accidents in Asia. DESIGN: Study based on 41 538 traffic accidents involving taxis in Singapore and 1 814 320 traffic accidents in Taiwan, combined with 12 788 European club football games over a seven year period. SETTING: Singapore and Taiwan. PARTICIPANTS: The largest taxi company in Singapore, with fine grained traffic accident records in a three year span; all traffic accident records in Taiwan in a six year span. EXPOSURE: Days when high profile football games were played or not played. MAIN OUTCOME MEASURE: Number of traffic accidents. RESULTS: Regression based and time series models suggest that days with high profile European football matches were more positively associated with traffic accidents than days with less popular European football matches. For an approximate €134.74m (£120.25m; $159.76m) increase in average market value for matches played on a given day, approximately one extra accident would occur among Singapore taxi drivers, and for an approximate €7.99m increase in average market value of matches, approximately one extra accident would occur among all drivers in Taiwan. This association remained after control for weather conditions, time of the year, weekend versus weekday effects, driver demographics, and underlying temporal trends. It was also stronger for daytime traffic accidents than for night time traffic accidents, suggesting that the association between high profile football matches and traffic accidents cannot be attributed to night time celebration or attention deficits while watching and driving. Annually, this increased rate of traffic accidents may translate to approximately 371 accidents among taxi drivers in Singapore and approximately 41 079 accidents among the Taiwanese public, as well as economic losses of approximately €821 448 among Singapore taxi drivers and approximately €13 994 409 among Taiwanese drivers and insurers. The total health and economic impact of this finding is likely to be much higher because GMT+8 is the most populous time zone, encompassing 24% of the world's population. CONCLUSIONS: Days featuring high profile football matches in Europe were associated with more traffic accidents in Taiwan and Singapore than were days with lower profile football matches. A potential causal mechanism may be Asian drivers losing sleep by watching high profile European matches, which are often played in the middle of the night in Asia.

The rise of COVID-19 cases is associated with support for world leaders.

COVID-19 has emerged as one of the deadliest and most disruptive events in recent human history. Drawing from political science and psychological theories, we examine the effects of daily confirmed cases in a country on citizens' support for the political leader through the first 120 d of 2020. Using three unique datasets which comprise daily approval ratings of head of government (n = 1,411,200) across 11 world leaders (Australia, Brazil, Canada, France, Germany, Hong Kong, India, Japan, Mexico, the United Kingdom, and the United States) and weekly approval ratings of governors across the 50 states in the United States (n = 912,048), we find a strong and significant positive association between new daily confirmed and total confirmed COVID-19 cases in the country and support for the heads of government. These analyses show that political leaders received a boost in approval in the early months of the COVID-19 pandemic. Moreover, these findings suggest that the previously documented "rally 'round the flag" effect applies beyond just intergroup conflict.

Sleep Loss and the Socio-Emotional Brain.

Are you feeling emotionally fragile, moody, unpredictable, even ungenerous to those around you? Here, we review how and why these phenomena can occur as a result of insufficient sleep. Sleep loss disrupts a broad spectrum of affective processes, from basic emotional operations (e.g., recognition, responsivity, expression), through to high-order, complex socio-emotional functioning (e.g., loneliness, helping behavior, abusive behavior, and charisma). Translational insights further emerge regarding the pervasive link between sleep disturbance and psychiatric conditions, including anxiety, depression, and suicidality. More generally, such findings raise concerns regarding society's mental (ill)health and the prevalence of insufficient and disrupted sleep.

Leader sleep devaluation, employee sleep, and unethical behavior.

OBJECTIVES: The objectives of this study is to examine the effect of leader sleep devaluation (which we define as leader behaviors that signal to employees that sleep should be sacrificed for work) on the sleep and unethical behavior of subordinates. DESIGN: Across 2 studies (with 3 total samples of participants), we use a cross-sectional survey, a diary study completed by employees, and a diary study completed by employees and their leaders. SETTING: Study 1 - a convenience sample of working adults in Italy, including 575 subordinates nested under 140 leaders. Study 2A - 135 working adults recruited from Amazon's Mechanical Turk. Study 2B - 127 employee-supervisor dyads recruited from the Study Response project. MEASUREMENTS: Survey measures of leader behaviors, subordinates sleep, and subordinate unethical behavior. RESULTS: Sleep devaluing leader behavior has harmful effects on employee sleep, and that these effects occur above and beyond the effects of abusive supervision and other alternative explanations. Subordinate sleep quality has a mediating role between leader sleep devaluation and subordinate unethical behavior. Effects for sleep quantity were inconsistent. CONCLUSIONS: Leaders can adversely influence the sleep and work experience of their subordinates. Specifically, sleep devaluing leader behavior undermines subordinate sleep, which in turn is associated with higher levels of subordinate unethical behavior.

Why healthy sleep is good for business.

People spend large portions of their lives working, often to the detriment of sleep. Businesses often ignore the importance of employee sleep despite evidence showing sleep health is crucial to positive employee outcomes. In this review we address the effect of sleep on employee health, performance, and workplace relationships. We examine the impact of work characteristics on employee sleep. Finally, we discuss opportunities for businesses to improve employee sleep to maximize success.

Why so serious? A laboratory and field investigation of the link between morality and humor.

Previous research has identified many positive outcomes resulting from a deeply held moral identity, while overlooking potential negative social consequences for the moral individual. Drawing from Benign Violation Theory, we explore the tension between moral identity and humor, and the downstream workplace consequence of such tension. Consistent with our hypotheses, compared with participants in the control condition, participants whose moral identities were situationally activated (Study 1a) or chronically accessible (Study 1b) were less likely to appreciate humor and generate jokes others found funny (Study 2), especially humor that involved benign moral violations. We also found that participants with a strong moral identity do not generally compensate for their lack of humor by telling more jokes that do not involve moral violations (Study 3). Additional field studies demonstrated that employees (Study 4) and leaders (Study 5) with strong moral identities and who display ethical leadership are perceived as less humorous by their coworkers and subordinates, and to the extent that this is the case are less liked in the workplace. Study 5 further demonstrated two competing mediating pathways-leaders with strong moral identities are perceived as less humorous but also as more trustworthy, with differentiated effects on interpersonal liking. Although having moral employees and leaders can come with many benefits, our research shows that there can be offsetting costs associated with an internalized moral identity: reduced humor and subsequent likability in the workplace.

Bad behavior keeps you up at night: Counterproductive work behaviors and insomnia.

Drawing from recent research on counterproductive work behaviors (CWB) and moral self-regulation literature, we examine the intraindividual consequences of engaging in CWB. We posit that CWB represents morally discrediting work behaviors that can lead to moral deficits, create distress for perpetrators and ultimately result in insomnia. Specifically, we hypothesized that on days in which employees engage in CWB, they will tend to experience moral deficits and heightened levels of rumination that undermine their sleep that night. Moreover, we hypothesized that these effects will be stronger for those who are high in moral identity internalization. Data from 2 within-individual field studies and 1 experimental study provided consistent support for most of our hypotheses. Overall, we found that by engaging in CWB employees can create problems for their own sleep health. (PsycINFO Database Record
