At first, we generally investigate the short-time decoherence of a qubit nonlinearly coupling with a bath. The measure of the decoherence is chosen as the maximum norm of the deviation density operator. Then we concretely investigate the Josephson charge qubit (JCQ) model. It is shown that at the temperature T ∼ 30mK, the loss of fidelity (due to decoherence) of the JCQ is bigger than the DiVin...

To evaluate the psychometric properties of the Chinese (mainland) version of Job Content Questionnaire (JCQ), this validation study was conducted in university hospitals among 193 men and 581 women health care workers. The Cronbach's alpha coefficients for decision latitude, psychological job demands and social support ranged from 0.56 to 0.82, which indicated that psychological job demands had...

Job strain has become a major concern because of its potential impacts on worker well-being and performance. This cross-sectional study aimed to assess the prevalence of, and examine factors associated with, job strain among workers in a rubber-glove factory, in a central province of Thailand. A total of 200 workers aged 18–55 yr, who had worked at the factory for at least 6 months, completed t...

Over the past years, the World Wide Web (the Web) has grown into a huge global information source, at an astounding pace. While we are enjoying the rich and fresh information on the Web, the rapid and often unpredictable updates to the widely distributed information sources have made it harder to detect and capture the changes. Update monitoring is a promising area of research where the system ...

Purpose Occupational stress is one of the major phenomena that should be considered to maintain health and improve workforce productivity. The study was aimed for different task groups to determine the correlation between job stress, psychosocial factors and work ability. A cross-sectional study of 178 male workers in an air conditioning assembly factory was carried out. Three questionnaires— t...

BACKGROUND Healthcare workers including physicians, nurses, medical technicians and administrative staff experience high levels of occupational stress as a result of heavy workloads, extended working hours and time-related pressure. The aims of this study were to investigate factors associated with work stress among hospital staff members and to evaluate their health-promoting lifestyle behavio...

background: the job content questionnaire (m-jcq) is an established self-reported instrument used across the world to measure the work dimensions based on the karasek's demand-control-support model. objective: to evaluate the psychometrics properties of the malay version of m-jcq among nurses in malaysia. methods: this cross-sectional study was carried out on nurses working in 4 public hospital...

BACKGROUND The Health & Safety Executive Management Standards Indicator Tool (HSE-MS IT) is a questionnaire commonly used to assess work-related stress risks at an organizational level. A critical factor in determining whether this instrument is actually useful is that higher levels of stress risk in the work-design domains should predict higher levels of stress and stress-related outcomes in w...
