Aim: This study investigates the mediation of sleep quality between perceived health and occupational burnout in hospital nurses, considering the moderation of workplace violence and organizational culture. Background: Occupational factors lead to physical and mental distress, burnout, and sleep issues in nurses. Approximately two‐thirds of nurses experience burnout, impacting patient care quality and safety. Cultivating a positive organizational culture is essential for nursing workforce stability. Methods: This cross‐sectional study employed convenience sampling to recruit 346 nurses from a teaching hospital in southern Taiwan in July–August 2020 (response rate: 87.3%). Self‐administered questionnaires containing validated instruments were employed, including an adapted occupational burnout scale, the Chinese version of an organizational culture scale, a Perceived Health Questionnaire, a Workplace Violence Experience Scale, and the CPSQI; all instruments were reliable and valid. The analysis involved descriptive statistics, linear regression, and the Johnson–Neyman technique. Results: Nurses with better perceived health exhibited significantly lower occupational burnout (p < 0.001). Perceived health indirectly impacted burnout through sleep quality (p < 0.01) with organizational culture as a partial moderator. Bureaucratic organizational culture exacerbated this relationship. Additionally, decreased workplace violence moderated the connections among perceived health, sleep quality, and occupational burnout among nurses. Conclusions: Given the inverse correlation between nurses' perceived health and occupational burnout and considering factors such as workplace violence, organizational culture, and sleep quality, healthcare institutions can proactively take steps to enhance nurses' overall well‐being and mitigate burnout. Implications for nursing and health policy: By implementing wellness programs, mental health support, security training, robust reporting, and a zero‐tolerance approach to violence, healthcare stakeholders can foster a safe and supportive work environment for nurses, thus improving well‐being, patient outcomes, and healthcare quality.

In this work, a sediment core collected from the Jiulong River estuary in southeastern China was subjected to 14C dating of foraminifera, as well as lignin, total organic carbon, and stable carbon isotope (δ13C) analyses in order to determine the impacts of climate change and human activities on the sedimentary organic matter in this area from around 2,000 to 1,000 years ago. The ratios of lignin parameters syringyl/vanillyl and cinnamyl/vanillyl ranged from 1.60 to 8.63 and 0.11 to 0.45, respectively, and the lignin phenol vegetation index ranged from 25.14 to 1740.14, indicating the presence of non-woody angiosperms. The ratio of vanillic acid/vanillin ranged from 0.42 to 2.04, indicating medium to high degrees of oxidative degradation. The vertical distribution profile showed a similar historical sedimentary trend with locations at higher latitudes along the Zhejiang-Fujian Mud Area, with the lower abundance of total lignin from around 2400 to 2000 BP being attributed to the decreasing temperature during this period. However, all the lignin parameters showed higher values and greater fluctuations due to increasing temperatures after 2000 BP, and human activity has probably had the greatest impact in the most recent 1,000 years.

Aim: To assess heart rate variability (HRV) as a measure to assess job stress and sleep quality among nurses in the post‐COVID‐19 period. Background: The COVID‐19 pandemic significantly affected nurses, with heightened job stress and impaired sleep quality impacting their well‐being and effectiveness in patient care. HRV could offer insights for supporting strategies in the pandemic aftermath. Design: A quantitative cross‐sectional study. Methods: This study involved 403 clinical nurses recruited from a teaching hospital in Taiwan. Data on job stress, work frustration, sleep quality and HRV were collected and analysed. Results: Among the nurses surveyed during the COVID‐19 pandemic, 72.7% reported poor sleep quality (PSQI = 9.369). Job stress emerged as a strong predictor of work frustration. High stress levels and poor sleep quality were correlated with significantly decreased HRV, indicating a potential physiological impact of stress on the nurses' health and well‐being. Conclusions: HRV is a valuable and cost‐effective measure for monitoring and managing nurses' well‐being in the post‐COVID‐19 era. Targeted interventions can be implemented to support nurses' overall performance and promote their well‐being by identifying those at high risk of job stress and poor sleep quality. Summary statement: What is already known about this topic? The COVID‐19 pandemic significantly impacted medical care capacity, leading to heightened physical and mental distress among frontline nurses. This has resulted in a marked increase in job stress, presenting a significant challenge to occupational health.The substantial changes in the medical environment caused by the pandemic are likely to induce job stress, which, in turn, can detrimentally affect sleep quality. This aspect is crucial, as sleep quality is a key determinant of nurses' ability to deliver optimal medical care to patients. What this paper adds? Job stress significantly impacts nurses' sleep quality and is a key predictor of work frustration, surpassing the sole influence of work frustration.The study highlights a significant link between high stress levels, reduced sleep quality and decreased heart rate variability in nurses. It further reveals that nurses with moderate COVID‐19‐related anxiety show heightened heart rate variability, indicating sympathetic nervous system activation to maintain alertness in emergency medical situations. The implications of this paper: Moderate anxiety as a positive factor: moderate levels of anxiety among nurses can contribute to maintaining alertness, reducing errors and lowering the risk of contracting COVID‐19.HRV as a monitoring and management measure: heart rate variability is a valuable and cost‐effective measure for monitoring and managing the health of nurses in the post‐COVID‐19 era. By identifying nurses with high work stress and poor sleep quality, targeted interventions can be implemented to support their overall performance and promote their well‐being.Targeted interventions for improved well‐being: the implementation of specific interventions aimed at supporting nurses' overall performance and enhancing their well‐being is crucial in maintaining a high standard of patient care.

Objectives: Patient safety is regarded as a critical quality monitoring indicator for medical institutions. The effects of a multimedia‐based patient education intervention on knowledge, attitudes, and behaviors regarding fall prevention were observed. Methods: The study had a quasi‐experimental research design and enrolled 140 participants. Seventy participants in the experimental group received multimedia‐based patient education and a health education leaflet, while those in the control group received only the health education leaflet. A structured questionnaire was used for data collection at baseline, and a posttest was applied after the intervention. Results: The participants were predominantly treated in the gastroenterology department (45.7%), followed by the pulmonology department (33.6%). A total of 86.4% of patients had not experienced a fall within 3 months. After the intervention, the average scores for all variables in the experimental group were higher than those in the control group. The results indicate that attitudes, knowledge, and behaviors regarding fall prevention among patients in the pulmonology department were higher than those among patients in the gastroenterology department; the differences were statistically significant. Conclusion: The individualized health education content was of substantial significance for patients with different disease backgrounds and facilitated changes in their knowledge, attitudes, and behaviors regarding falls. Relevance to clinical practice: Multimedia‐based patient education influenced inpatients' knowledge, attitudes, and behaviors for preventing falls. [ABSTRACT FROM AUTHOR]

Game-based teaching strategies enrich nursing education by enhancing the appeal and practicality of teaching activities. Different from the high-pressure and serious nature of traditional nursing education, interactive and entertaining teaching strategies that employ board games, card games, escape rooms, virtual reality, scratch cards, Kahoot quiz competitions, and other innovative methods better motivate learners to engage actively with learning content and retain nursing knowledge and practices, resulting in better learning outcomes. Game-based teaching strategies not only strengthen learners' mastery of core nursing concepts but also enhance their decision-making and critical-thinking abilities. In this article, practical applications of game-based teaching are introduced, in hopes that, by applying these instructional approaches, educators can alleviate the stress of the learning process and make learning more efficient and enjoyable for students.

Elimination of molecular bromine is probed in the B (3)Pi(ou) (+)<--X (1)Sigma(g) (+) transition following photodissociation of CHBr(2)Cl at 248 nm by using cavity ring-down absorption spectroscopy. The quantum yield for the Br(2) elimination reaction is determined to be 0.05+/-0.03. The nascent vibrational population ratio of Br(2)(v=1)Br(2)(v=0) is obtained to be 0.5+/-0.2. A supersonic beam of CHBr(2)Cl is similarly photofragmented and the resulting Br atoms are monitored with a velocity map ion-imaging detection, yielding spatial anisotropy parameters of 1.5 and 1.1 with photolyzing wavelengths of 234 and 267 nm, respectively. The results justify that the excited state promoted by 248 nm should have an A(") symmetry. Nevertheless, when CHBr(2)Cl is prepared in a supersonic molecular beam under a cold temperature, photofragmentation gives no Br(2) detectable in a time-of-flight mass spectrometer. A plausible pathway via internal conversion is proposed with the aid of ab initio potential energy calculations. Temperature dependence measurements lend support to the proposed pathway. The production rates of Br(2) between CHBr(2)Cl and CH(2)Br(2) are also compared to examine the chlorine-substituted effect.

Following photodissociation of CH2Br2 at 248 nm, Br2 molecular elimination is detected by using a tunable laser beam, as crossed perpendicular to the photolyzing laser beam in a ring-down cell, probing the Br2 fragment in the B 3Piou+ -X 1Sigmag+ transition. The nascent vibrational population is obtained, yielding a population ratio of Br2(v = 1)Br2(v = 0) to be 0.7 +/- 0.2. The quantum yield for the Br2 elimination reaction is determined to be 0.2 +/- 0.1. Nevertheless, when CH2Br2 is prepared in a supersonic molecular beam under cold temperature, photofragmentation gives no Br2 detectable in a time-of-flight mass spectrometer. With the aid of ab initio potential energy calculations, a plausible pathway is proposed. Upon excitation to the 1B1 or 3B1 state, C-Br bond elongation may change the molecular symmetry of Cs and enhance the resultant 1 1,3A'-X 1A' (or 1 1,3B1-X 1A1 as C2v is used) coupling to facilitate the process of internal conversion, followed by asynchronous concerted photodissociation. Temperature dependence measurements lend support to the proposed pathway.
