Lack Of Knowledge

TikTok is one of the most popular apps. TikTok's endless stream of content, the lack time stamps or notifications of ever being “all caught up,” and concealing the phone's clock make it easy to lose track of time on TikTok. However, there is a lack of knowledge about how TikTok use may therefore interfere with our circadian rhythms, particularly our sleep hygiene. By focusing on pre-sleep cognitive arousal, this study aimed to close this knowledge gap by investigating the association between automatic TikTok use and daytime fatigue. We also investigated how individual preferences for sensation seeking and delayed gratification moderated this relationship. Within a sample of 1,050 TikTok/Douyin users in China, automatic TikTok use was associated with increased daytime fatigue that was mediated by higher levels of cognitive arousal before sleep. This relationship was aggravated by a preference for sensation seeking, and attenuated by a preference for delayed gratification. Above and beyond these early empirical insights, we also provide an early explanatory framework that is meant to systematize both existing and future knowledge about the use of TikTok.

Lack Of Knowledge

This chapter reflects on experiences when traditional IT approaches were used to design large IT systems and ended in failure (Etheridge, 2001). The main reflections focus on the reasons for system failure and how they relate to the diversity of knowledge, managing knowledge, and the understanding gaps that may exist between the business and the system developers. The study reveals that the understanding gaps mainly result from lack of knowledge of business operations on the developer side, matched by lack of technical appreciation and knowledge on the user side. To help address the knowledge gap problem, a Knowledge Requirement Framework (KRF), employing soft-systems, diagramming and set mapping techniques, is proposed and d

Circadian rhythms and the mechanisms of sleep and wakefulness begin to form in the embryonic period and undergo many stages of development before acquire characteristics typical for an adult. Structure of sleep disturbances in children also differs from that in the adult population. Most sleep disorders in children are the result of immaturity of certain brain structures and mechanisms: primary sleep disorders, pediatric behavioral insomnia, sleepwalking, night terrors, enuresis. These disorders are benign, and usually disappear by adulthood. Treatment of benign sleep disorders in children should primarily be based on the methods of behavioral therapy, the rules of sleep hygiene and the purpose of light sedation.

Obstructive Sleep

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder which affects the reproductive, metabolic and psychological health of women. Now a day’s incidence rate of PCOS is incising in reproductive age of woman due to sedentary lifestyle and faulty daily routine. Clinical studies indicate that sleep disturbance and disorders including obstructive sleep apnea and excessive daytime sleepiness are more common in the woman with symptoms of PCOS. Despite proof of the high prevalence of sleep disorders in these patients, modification of sleep is not considered as major point for treatment protocol in modern therapeutics. Ayurveda as a holistic medicine lays great emphasis on lifestyle modification under Aahaara (Diet)- Vihaara (Daily regimen)- Oushadha (Medicine) - triad for the prevention and treatment of all diseases. Among Vihaara, Nidra (Sleep) is considered as a very influencing factor in Ayurvedic classics. Balanced sleep at night maintains the health. Disturbance of sleep pattern can lead to Dosha vitiation which hampers regular metabolic activity of the body and leads to various disorders. Hormones affecting metabolism, appetite and blood glucose are regulated with circadian rhythms. When circadian rhythms are out of sync, the body’s metabolic health hampers. Irregular metabolic function disturbs the hormonal cycle including hypothelamo-pitutory-ovarian axis, hypothalamic–pituitary–adrenal function, and so on.  These can ultimately lead to PCOS in reproductive age of women. It seems that if lifestyle modification should be expanded in PCOS patients including sleep hygiene alongside food and exercise positive outcome can be obtained. With this background this study is aimed to determine the importance of sleep hygiene in PCOS from the view of Ayurveda.

Pain Patients

Sleep deprivation is arguably the single most compromising event that prevents pain patients from changing behavior. To get the sleep-deprived patient to take action to improve their sleep and become more capable of healthy change, healthcare practitioners must approach the patient with the evidence of “what works,” but on his or her own terms, in a language that he or she can understand and cognitively retain, and in a psychological manner that will inspire hope and increase motivation. This chapter endeavors to accomplish the following: (1) review the scope of the problem; (2) clarify the frame of reference of the author; (3) explain how humans function as living rhythm machines; (4) define circadian rhythms, chronobiology, and clock genes; (5) describe the challenges of improving sleep hygiene in a patient population; and (6) identify the methods of change used clinically, including motivational interviewing.

Improve Sleep Quality

Prevalence of sleep problems has grown globally in recent years and sleep hygiene recommendations have shown inconsistent results. This study aims to analyze the quality of sleep in a non-clinical population and its association with maladaptive sleep hygiene. A total of 465 participants, with median age of 35 years (Interquartile range ? IQR = 28?44), completed the Sleep Hygiene Practices Scale (SHPS) and the Pittsburgh Sleep Quality Index (PSQI). Sample was divided into good quality sleepers (GQS; 52.7%, n = 245) and poor quality sleepers (PQS; 47.3%, n = 220). Comparison tests showed PQS had significant higher scores on SHPS (M = 61; IQR = 55?68, p < .01) compared with GQS (M = 68; IQR = 62?74). A logistic regression model indicated that only cognitive-arousal behaviors and inconsistent bedtimes were significant to classify poor sleep (R2 = .35; p < .01). In conclusion, poor sleep quality is common among healthy individuals and strongly associated with pre-sleep cognitive activity. This suggests that interventions aiming to improve sleep quality should consider strategies that would retract attention from concerns and worries at bedtime.

Telepractice, defined by the American Speech-Language-Hearing Association (ASHA, n.d.) as “the application of telecommunications technology to the delivery of professional services at a distance by linking clinician to client, or clinician to clinician, for assessment, intervention, and/or consultation,” is a quickly growing aspect of practicing audiology. However, only 12% of audiologists are involved in providing services via telepractice (REDA International, Inc., 2002). Lack of knowledge regarding telepractice has been cited as one of the reasons many audiologists do not use telepractice to provide audiology services. This study surveyed audiology doctoral students regarding their opinions about the use of telepractice both before and after their opportunity to provide services via telepractice sessions. The authors expected that by providing students the opportunity to have hands-on training in telepractice with supervision, they would be more open to using telepractice after becoming licensed audiologists. Overall, the data indicates benefits of exposing students to telepractice while they are in graduate school.

Psychometric Investigation

Abstract: Zuckerman postulated a biopsychological multilevel theory of Sensation Seeking, which is part of a more complex multi-trait theory, the Alternative Five. The Sensation Seeking Scale Form V (SSS V) was developed for the measurement of Sensation Seeking. The process of validation of Sensation Seeking as part of a multilevel theory includes analyses of relations within and between several levels of measurement. The present study investigates validity and basic psychometric properties of a German version of the SSS V in a broader context of psychometric traits. - The 120 participants were mainly students. They completed the SSS V, the Venturesomeness- and Impulsiveness-Scales of the IVE, the BIS/BAS-Scales, the ZKPQ and the NEO-FFI. - The results reveal acceptable psychometric properties for the SSS V but with limitations with regard to factor structure. Indications for criterion validity were obtained by prediction of substance use by the subscales Dis and BS. The results of a MTMM analysis, especially the convergent validities of the SSS V were quite satisfying. On the whole, the results yielded sufficient support for the validity of the Sensation Seeking construct or the instrument respectively. They also point to desirable modifications.

Abstract: Among many other changes, older age is characterized by advanced sleep-wake cycles, changes in the amplitude of various circadian rhythms, as well as reduced entrainment to zeitgebers. These features reveal themselves through early morning awakenings, sleep difficulties at night, and a re-emergence of daytime napping. This review summarizes the observations concerning the biological clock and sleep in the elderly and discusses the documented and theoretical considerations behind these age-related behavioral changes, especially with respect to circadian biology.

Abstract. The structure, correlates, and assessment of the Dark Triad are widely discussed in several fields of psychology. Based on the German version of the Short Dark Triad (SDT), we add to this by (a) providing a competitive test of existing structural models, (b) testing the nomological network, and (c) proposing an ultrashort 9-item version of the SDT (uSDT). A sample of N = 969 participants provided data on the SDT and a range of further measures. Our competitive test of five structural models revealed that fit indices and nomological network assumptions were best met in a three-factor model, with separate factors for psychopathy, Machiavellianism, and narcissism. The results provided an extensive overview of the raw, unique, and shared associations of Dark Triad dimensions with narcissism facets, sadism, impulsivity, self-esteem, sensation seeking, the Big Five, maladaptive personality traits, sociosexual orientation, and behavioral criteria. Finally, the uSDT exhibited satisfactory psychometric properties. The highest overlap in expected relations between SDT and uSDT, and convergent and discriminant measures was also found for the three-factor model. Our study underlines the utility of a three-factor model of the Dark Triad, extends findings on its nomological network, and provides an ultrashort instrument.
