Reliability and validity of Job Content Questionnaire in Chinese petrochemical employees

To evaluate psychometric properties the Chinese (mainland) version of the 30-item Job Content Questionnaire was administered to 889 employees in 4 industries of PetroChina. A retest at 3 months with 296 randomly chosen employees showed reliabilities ranged from .76 to .93. Cronbach coefficients alpha for the 8 dimensions ranged from .43 to .88, indicating that the Job Insecurity subscale had low internal consistency. Exploratory factor analysis showed 8 meaningful factors corresponding to the 8 theoretical dimensions of this questionnaire. This version has variable a but suitable retest to be a reliable and valid measure of job strain, applicable to the Chinese industrial working population of PetroChina.     

HERG钾通道抑制——祸兮？福兮？

过去的10多年,许多药物由于引起QT闯期延长被撤市或限制使用,原因可能是HERG钾通道受到抑制,可诱发致死性心律失常。抑制HERG钾通道的药物因而成为临床用药的潜在祸患。另一方面,HERG钾通道还参与癌症和骨骼肌萎缩的发病过程,提示HERG钾通道抑制荆可能对这些疾病具有潜在治疗价值。HERG钾通道抑制究竟是“祸”还是“福”呢？本文就这一现象进行讨论。     

《管子·轻重》成书当在战国时代

通观《轻重》各篇内容,无论从时代背景、从封君与“乡州”地方政府、郡县制度、从战国田齐政权“王天下”与春秋齐桓公时“尊王攘夷”的政治形势不同、从田齐货币、从田齐“釜、钟”等量具、从租金形式等方面来看,《管子.轻重》著作年代在田齐威、宣王或稍后的战国时代,而并非春秋齐桓公、管仲的时代,也非汉代。

50% off or buy one get one free? Frame preference as a function of consumable nature in dairy products

Previous studies on how framing differentially affects consumer perceptions of value from equivalent deals indicate that perceptions of deal value from price-saving versus extra-product promotions are moderated by the stock-up characteristic of the category. In this study, the authors explored the relationship between stock-up characteristic and frame preference and the influence of the consumable nature of goods on frame preference. An experiment involving 223 student participants showed that consumable nature, but not stock-up characteristic, affected frame preference. The authors discuss the implications of this finding for the study of information framing and how it impacts consumer judgment and decision making.     

VR-based conversation training program for patients with schizophrenia: a preliminary clinical trial.

Schizophrenia is a devastating mental illness and is characterized by hallucinations and delusions as well as social skills deficits. Generally, social skills training designed to help patients develop social skills includes role-playing, but this form of training has typical shortcomings, which are largely due to a trainer's difficulties to project emotion. Virtual reality (VR)-based techniques have the potential to solve these difficulties, because they provide a computer-generated but realistic three-dimensional world and humanlike avatars that can provide emotional stimuli. In this paper, we report on a method of implementing virtual environments (VEs) in order to train people with schizophrenia to develop conversational skills in specific situations, which could overcome the shortcomings of or complement conventional role-playing techniques. The paper reports the efficacy of the proposed approach in a preliminary clinical trial with 10 patients with schizophrenia.     

Characteristics of social perception assessed in schizophrenia using virtual reality.

Impairment in social skills is one of the few criteria that all individuals diagnosed with schizophrenia must meet. Successful social skills require the coordination of many abilities, including social perception, which involves the decoding and interpretation of social cues from others. In this study, we examined the potential for virtual reality (VR) in social skill training. We attempted to determine if VR can be used to measure social skills and social perception, and to determine which VR parameters are related to schizophrenic symptoms. Some of these results have clear clinical relevance, while other observations need further study. The VR system appears to be useful in assessing the social perception of schizophrenics and normal people, and could be more widely used in the future for social training and in the assessment of social problem-solving abilities, assertiveness skills, and general social skills.
