The Impact

AbstractAlthough poor sleep has been found to correlate with deteriorations in romantic relationships, its causal impact on interpersonal conflict has not previously been studied. Therefore, 30 couples were randomly assigned to either a single night of total sleep deprivation or a night of normal sleep to test the effects of sleep deprivation on couples’ conflict. After the experimental night, all participants discussed a topic of recurrent conflict for 15 min. We collected pre- and post-conflict measures of cortisol, self-reports of feelings, and satisfaction with the conflictual discussion. Multilevel analyses revealed higher cortisol levels during conflict and less positive affect prior to and after the conflict for sleep-deprived couples compared to couples in the control condition. These findings provide initial evidence for a causal negative impact of sleep deprivation on couples’ conflicts.

Abstract Background Lack of sleep amongst surgeons is significant and worrying. It poses short- and long-term risks to surgeons’ health and negatively impacts patient outcomes. Previous studies have examined sleep deprivation amongst health care professionals. The aim of the present study was to examine impact in a specific population of surgical doctors. Method A questionnaire-based study completed in the anatomy department of King’s College London University. Surgical subjects spanned the United Kingdom. Subjects completed 14 questions regarding sleep habits. Data was compiled, calculating a sleep deprivation score. Results Valid responses were obtained from 66 surgical subjects of varying seniority. Mean age of subjects was 33.7 years old. 59.1% of subjects had rota commitments changing on a weekly basis. Average sleep amongst subjects amounted to 6.15 (± 1.26) hours per night. Daily sleep did not present differences dependent on seniority level (p = 0.186). 25.8% of subjects took >30 minutes to fall asleep. Our subjects woke 1.67 (± 1.21) times a night. Mean sleep deprivation score amongst our surgical population was 16.5 (± 4.26) demonstrating moderate negative impact on daily activities. 28.9% accumulated ≧20 sleep deprivation score demonstrating severe impact of sleep deprivation on life. Conclusions Our study has demonstrated reduced quantity and quality of sleep amongst our subject population. With protecting the health of both patients and surgeons in mind, we must place higher importance on improving sleep amongst surgical professionals.

Abstract Study Objectives This study assesses the impact of sleep deprivation and text messaging on pedestrian injury risk. Methods A total of 36 university students engaged in a virtual reality pedestrian environment in two conditions: sleep deprived (no sleep previous night) and normal sleep (normal sleep routine). Sleep was assessed using actigraphy and pedestrian behavior via four outcomes: time to initiate crossing, time before contact with oncoming vehicle, hits/close calls, and looks left/right. During each condition, participants made half the crossings while text messaging. Participants also completed the Useful Field of View test, the Psychomotor Vigilance Test, and Conners’ Continuous Performance Test in both conditions. Results While sleep deprived, students crossed significantly closer to oncoming vehicles compared with after normal sleep. While text messaging, crossed closer to vehicles and took longer to initiate crossings. Safety risks were amplified through combined sleep deprivation plus text messaging, leading to more virtual hits and close calls and shorter time before vehicle contact while crossing. Sleep-deprived students demonstrated impairments in functioning on cognitive tests. Conclusions University students’ pedestrian behavior was generally riskier, and their cognitive functioning was impaired, when sleep deprived compared with after normal sleep. This effect was exacerbated when distracted by text messaging.

Culture Of Origin

Intercultural communication has been considered as an effective tool in performing international business in overseas subsidiaries. In this paper, we investigate the impact of intercultural communication on interpersonal conflict between expatriates and Thai managers during the new product development process, and how expatriates’ culture of origin moderates this impact. Data were collected through a questionnaire survey from local managers who regularly communicate with expatriate managers working in Thailand. The results show that intercultural communication reduces relationship conflict and increases task conflict. Furthermore, the negative impact of intercultural communication on relationship conflicts between Asian expatriates and Thai managers is stronger than between Western expatriates and Thai managers. The research results contribute to the existing theories by extending inter-functional communication and conflict to an intercultural context. Also, this research enhances understanding on how the impact of intercultural communication on conflict is moderated by expatriates’ culture of origin, namely Asian and Western. Managerial implications for MNC subsidiaries and future research are also discussed.

The Impact

Background: Social media (SM) use among young adults has increased significantly in recent years and has been linked to poor sleep quality. College athletes pose a unique risk for poor sleep given their many demands. Currently, limited research is available on the impact of SM use on sleep quality, or the competition performance of college athletes. Hypothesis: College athletes who use more SM will have worse sleep quality and worse competition performance. Methods: A cross-sectional study design was employed among local NCAA Division III athletes. Data was collected via a SM use form, lifestyle survey, and PROMIS sleep disturbance questionnaire. SM volume (hours of SM use per day over 7 days) was recorded using the iPhone screen time function. The main outcome measures were sleep quality, using the PROMIS T-score, and performance, collected through publicly available competition results. Participants were divided into 3 groups based on their SM volume; 1) moderate SM users (SM time ≤ 2hours/day), 2) active SM users (SM time < 2 - ≤5hours/day), and 3) super active SM users (SM time > 5hours/day). For sleep quality, an ANCOVA was used to identify differences in the 3 groups while controlling for covariates (i.e. injury status, caffeine use, number of roommates, academic load, catastrophic life event, life balance and sleep medication use) that might impact sleep and performance. For performance, a binary logistic regression model was used to determine the independent association between each variable and competition performance after adjusting for confounders. Results: 87 athletes (age:19.5±1.2 years, 40 males, 47 females) completed the survey. All males participated in track and field, while the females consisted of 37 track athletes and 10 swimmers. Controlling for the effect of lifestyle variables, a difference in sleep quality was identified among the three groups (p=0.025), (Table 1. A pairwise comparison indicated that the sleep quality of super active SM users was worse than moderate SM users (p=0.033) (Figure 1). For competition performance, an independent association was found between increased Facebook time and poor performance after adjusting confounders (aOR: 0.989, 95%CI: 0.978-0.999, p=0.038), (Table 2,3). Conclusion: High SM use appears to have a negative impact on sleep quality. Also, greater SM use may hinder competition performance among college athletes. These findings may have implications for developing SM use guidelines for college athletes to improve their sleep quality and performance.

Abstract Objective: Sleepiness caused by poor sleep hygiene may increase the risk of injuries and damages during physical activity. Individual data so far indicate a generally better static postural stability of women regardless of sleeping conditions. The main aim of this study was to assess the impact of sleep deprivation on postural stability according to gender after 24 hours of sleep deprivation. Methods: Participants included 83 students (36 men and 47 women). Postural stability was measured with eyes open and closed eyes before and after sleep deprivation. Data from posturographic platform were used to assess postural stability objectively. Results: The type of test determined the size of observed changes in postural stability. The data suggest that women are better able to cope with the effects of sleep deprivation than men. Conclusion: Postural control system is very important in sport and in physically active people. The results show that men are more sensitive to sleep deprivation than women because they had higher COP path length values in tests. Less postural stability of the body due to sleep deprivation indicates a higher risk of injury during physical activity.

Budget Cycles

Studies of political budget cycles in developing countries have generally sought to inform understanding of short-term fiscal dynamics, but can also offer unique insight into broader political dynamics in developing countries. This article correspondingly employs markedly improved data in order to study the impact of elections on tax collection, and draw broader lessons. It shows that while electionsas a grouphave had no significant effect on tax collection, the subset ofcompetitive electionshas had a significant negative impact on pre-election tax collection; while this effect appears to be largest where incumbents are particularly unpopular. This provides powerful evidence that the impact of elections on political incentives in developing countries is conditioned by the existence of an electorally competitive opposition, while offering preliminary evidence that popular resistance to taxation by unpopular governments may be an important means by which taxpayers may generate pressure for improved governance.

Purpose This paper aims to investigate impact of coronavirus COVID-19 on children’s mental health specifically emotional and behavioral disorders. It aims at identifying the main disorders faced by children during epidemics and suggests recommendations to nurture resilience among children and involving them in various positive activities. Design/methodology/approach This study is based on review of literature focused on COVID-19. Recent articles related to coronavirus or COVID-19 and psychological distress among children were included to draw conclusion and impact of COVID-19 on mental health of children. Due to the limited availability of studies on CONID-19 impact on mental health of children, studies focused on recent pandemic were focused. Findings The identified literature reports a negative impact of COVID-19 on individual’s mental health. Relatives’ health, poor appetite, fear of asking questions about epidemics, agitation, clinginess, physical discomfort, nightmares and poor sleep, inattention and separation issues were among the major psychological conditions analyzed. Personal attributes such as resilience, should be nurtured so that children will be empowered to manage difficult situations such as traumas and disappointments. Several measures were suggested by pediatricians in China to family members and parents such as playing games with children to reduce feeling of loneliness, increased communication to address their concerns and fears, promoting and encouraging physical activities and involving in musical activities to reduce fear, worry and stress among children. Originality/value Coronavirus is new pandemic and growing rapidly. most of the research studies are focused on physical health of individuals, but mental health concept has bene overlooked. This study helps to broaden the scope of research on children's mental health by examining the impact of COVID-19.

Abstract This study explores the impact of corporate default risk on environmental deterioration in the international context. We find that corporate bankruptcy is positively associated with CO2 emissions and its decomposed components. These findings are reliable in low-income and highly uncertain countries but weak in countries having more market competition. We also find that the negative impact of corporate default risk on environment is more robust in countries with more population density and less forest area thresholds. Using instrumental variable approach, we provide preliminary evidence that firm-level political risk (for U.S. and Canadian firms only) tend to increase corporate default risk leading to degrading environment. Our research will help environmental authorities to consider corporate-default risk as a determinant when formulating environmental-related strategies.
