Objectives: This study examines the mediating and moderating effects of characteristics of sleep disorders on the impact of smartphone overuse on academic delay in dental hygiene students. Methods: A survey was conducted from October 19 to November 27, 2020, targeting 164 dental hygiene students in Busan and Daejeon. The analysis method used the SPSS 26.0 program. Results: As a result of analyzing the characteristics of sleep disorders, it was found that as the characteristics of sleep disorders increased, the influence of excessive use of smartphones on academic delay behavior increased (p<.001). Sleep disorder characteristics were found to partially mediate smartphone overuse and academic delay behavior, indicating that the sleep disorder characteristics were significant. Conclusions: This study explores the relationship between smartphone use and the sleeping habits of dental hygiene students and the impact of these factors on academic performance

This paper analyzes the effect of offshore outsourcing on the export performance of firms, based on the theories of international business, the resource-based view of the firm and the transaction cost theory.Outsourcing can reduce production costs and increase flexibility. It can also provide new resources and market knowledge. However, the impact of offshore outsourcing depends on the resources and capabilities of firms to manage a network of foreign suppliers, and to absorb knowledge of foreign markets. Using a database of about 1,000 manufacturing companies in Mexico in 2011, we found that offshore outsourcing increases the performance of exports. The effects are stronger in export markets from which the company also imports intermediate goods.The results also show that the size of the company, the organization of intra-firm imports and export experience moderate the effects of outsourcing in a positive way.

The Impact

Autonomic dysfunctions are frequently associated with sleep disorders, as the autonomic nervous system and sleep are closely related from anatomical, physiological, and neurochemical points of view. The autonomic dysfunctions described in this chapter may result from a common pathogenetic mechanism that affects both the autonomic and the sleep functions, as in fatal familial insomnia, or from a prevalent expression of a primary disorder of autonomic regulation during sleep, as in congenital central hypoventilation syndrome. Alternatively, the autonomic dysfunction may be mainly caused by the sleep disorder, as observed in obstructive sleep apnea syndrome, or the causal mechanism resulting in the association between the autonomic dysfunction and the sleep disorder has yet to be identified with certainty, as in narcolepsy with cataplexy and in REM sleep behavior disorder. The impact of the autonomic dysfunction on health and on patients’ quality of life is also reviewed.

Practical Implications

PurposeResearch addressing the impact of tacit and explicit pay secrecy policies on organizational climates is fairly limited. While researchers desire to explain the impact of such policies on individuals' pay satisfaction, a direct effect has not been supported. This study seeks to better explain how these policies are related to ethical climates and pay satisfaction.Design/methodology/approachThis study draws on ethical climate theory to show the influence of ethical climate types on job satisfaction and a moderating effect of explicit and tacit pay secrecy policies on this relationship. This is accomplished through designing this study by using existing scales from the literature in a survey methodology. A pilot study of 246 undergraduate students was used to validate the measures. Then, a sample of 217 adults was obtained to test the proposed relationships. Linear regression is employed to analyze the data and to test the existence of direct and moderating effects.FindingsThe five empirically tested ethical climates each have a direct effect on pay satisfaction. Explicit pay secrecy policies has a positive moderating effect on the relationship between rules, law and code ethical climates, and pay satisfaction. Tacit pay secrecy policies moderate the relationship between caring, rules, law and code, and independence ethical climates and pay satisfaction.Research limitations/implicationsThe findings strengthen the literature by demonstrating a stronger relationship between ethical climates and pay satisfaction. While some of the moderating effects were significant, others were not. This was surprising, but present avenues to further test ethical climate theory and the impact of pay secrecy policies.Practical implicationsThis study presents practical implications for managers. Understanding how these policies may be viewed differently, depending on the type of climate that is experienced within an organization may help managers evaluate using them. Trying to protect employees or the organization itself by enacting these polices may backfire and create additional problems. Managers may want to evaluate the manner that they communicate these polices through formal or informal means, depending on the type of climate experienced within the workplace.Originality/valueThis study is the first to examine the influence of explicit and tacit pay secrecy policies on the relationship between ethical climates and employees' satisfaction with pay. It leads to a number of directions for further research that may continue to build upon this study in order to further advance scholarly understanding of the importance of ethical climates and pay secrecy policies.

AbstractThis study examines the impact of employability on turnover intention by differentiating internal and external employability, and considering the possible moderating roles of perceived organizational support (POS) and career orientation. Using a sample of 411 responses to a two-wave questionnaire survey generated from six cities in China, we find that external employability positively influenced turnover intention, but internal employability negatively influenced turnover intention. The results also indicate that POS had a positive moderating effect only on the relationship between external employability and turnover intention. Furthermore, for employees with disengaged career orientation, external employability exerts a strong impact on turnover intention. This study adds to the limited research empirically linking employability and turnover intention, whereas the findings can be used by HRM practitioners to factor in organizational support and career orientation initiatives that improve the retention of employees with high external employability.

SummaryDisordered sleep has long been recognised as both a consequence of psychiatric illness and a contributory factor to its development. Significant sleep disturbance occurs in about 25% of children and adolescents and 80% or more of children in high-risk groups; it often continues into adulthood. All psychiatrists should therefore be familiar with the principles of sleep medicine and the impact of sleep and its disorders. In this article, the relationship between sleep disorders and the breadth of child and adolescent psychiatry in particular is explored. The classification, aetiology and implications of sleep disorders are discussed, as well as the practicalities of screening, diagnosis and management, with a view to informing readers how accurate diagnosis, prevention and successful treatment of sleep disorders can benefit patients and their families.

To examine the association between sleep disorders, obesity status, and the risk of diabetes in adults, a total of 3668 individuals aged 40+ years from the NHANES 2009-2010 without missing information on sleep-related questions, measurements related to diabetes, and BMI were included in this analysis. Subjects were categorized into three sleep groups based on two sleep questions: (a) no sleep problems; (b) sleep disturbance; and (c) sleep disorder. Diabetes was defined as having one of a diagnosis from a physician; an overnight fasting glucose > 125 mg/dL; Glycohemoglobin > 6.4%; or an oral glucose tolerance test > 199 mg/dL. Overall, 19% of subjects were diabetics, 37% were obese, and 32% had either sleep disturbance or sleep disorder. Using multiple logistic regression models adjusting for covariates without including BMI, the odds ratios (OR, (95% CI)) of diabetes were 1.40 (1.06, 1.84) and 2.04 (1.40, 2.95) for those with sleep disturbance and with sleep disorder, respectively. When further adjusting for BMI, the ORs were similar for those with sleep disturbance 1.36 (1.06, 1.73) but greatly attenuated for those with sleep disorders (1.38 [0.95, 2.00]). In conclusion, the impact of sleep disorders on diabetes may be explained through the individuals’ obesity status.

This research aimed to investigate the impact of superior’s anger out on the employees’ creative process engagement, the mediating effect of negative mood, and the moderating effects of the personal identification with the leader. To examine these ideas, we conducted a survey and collected data from 211 employees of diverse organizations. Results result showed that superior’s anger out was positively related to the employees’ negative mood. The negative mood of the employees, however, had no significant effect on the creative process engagement and it did not mediate the relationship of the superior’s anger out with employees’ creative process engagement. Lastly, personal identification with the leader significantly moderated the relationship between the superior’s anger out and the employees’ negative emotion. That is, results revealed that those employees who had higher level of personal identification with the leader regarded his/her anger out as a signal of dissatisfaction toward their work performance, tended to exert more effort to resolve the problems creatively. Applied implications of the results are discussed.

Healthy sleep is not only the most important source of restoring the body's strength, but also a way to overcome traumatic events and stress, as well as a resource for the effective functioning of the human nervous system. Many studies confirm the relationship between the duration and quality of sleep and the health status of the population. At the same time, in modern conditions, socio-demographic characteristics of the population are of great importance in determining sleep. The main sleep disorders are recognized not only as a reduction in its duration, but also as a deterioration in quality (problems with falling asleep, a feeling of unreconstructed strength). The purpose of this article is to study the quantitative and qualitative characteristics of sleep in the population (including in the context of the main socio-demographic groups), the prevalence of factors of its disorders and their impact on subjective health assessments. The information base was data from monitoring of physical health of the Vologda oblast population in 2020 (n = 1500). The study identified risk categories for quantitative and qualitative sleep disorders; confirmed the relationship of stress factors, noise pollution and poor housing conditions with the frequency of sleep disorders; proved the impact of sleep problems on self-assessment of health.

Introduction: Sleep disorders are one of the main complaints of women in transition from menopause, with a prevalence between 40% and 56%. However, regardless of the etiology, it is essential to assess the symptoms of insomnia in the context of menopause, as well as physical and mental health. Objective: To investigate the relationship between the transition from menopause to the causes of insomnia. Methodology: In April 2021, a literature review was carried out on MedLine using the descriptors “insomnia”, “menopause” and their respective synonyms, published in the last 5 years and available in full. Results: 157 articles were found, 4 of which were used in making this work. The precise mechanism of vasomotor symptoms is little known, but the hypothesis is that it results from a disturbance of the temperature regulating system in the hypothalamus, triggered by a decline in estrogen. Longitudinal data show that women with moderate to severe hot flashes are almost three times more likely to report frequent nighttime awakenings compared to women without hot flashes (HF). Conclusion: Therefore, HF is an important aspect of insomnia in the transition from menopause and is strongly associated with reports of interrupted sleep.
