国际贸易实务课程设计与研究性教学相结合

实践教学是提高学生动手能力、培养分析问题和解决问题能力、将知识内化的最有效的手段.大连民族学院国际经济与贸易专业创造性地开展了“国际贸易实务课程设计”,将这一实践教学环节与研究性教学相结合,不仅实施了“做中学”教学方法,而且充分体现了“研究性教学”的教学设计思想,同时引入了“双语教学”,收到了良好的教学效果.     

康德与"科学"形而上学的构建

康德在继承近代哲学经验论与唯理论的基础之上进一步修正了哲学认识论理论,尽管他提出了“物自体”不可知的思想,但由认识论难以提示本体论的困难处境并没使他放弃建构形而上学的工作;相反,在论述伦理学与法权理论时,康德一直呼唤着形而上学。但由于他未能正确处理认识论与方法论的辩证关系,他并没有完成建构科学形而上学的任务。     

The basis of feeling-of-knowing judgments in patients with schizophrenia

We examined the basis of feeling-of-knowing judgments (FOK) in patients with schizophrenia. Such patients typically have impaired memory and awareness, but not metamemory-accuracy deficits. The magnitude of FOKs are lower for patients with schizophrenia than for healthy participants, but judgments equally predict memory performance. In healthy participants, FOK is based on accessible information, including retrieval of partial-target (e.g., retrieving the first letter) and contextual information (e.g., related facts). In Experiment 1, we examined if accessible information predicts FOKs for episodic memory in patients with schizophrenia. Patients and healthy controls learned names paired with drawings of imaginary animals. The results showed that patients’ FOK increased with the retrieval of partial-target and contextual information. In Experiment 2, using semantic-memory general-information questions, accessible partial-target information predicted FOKs in patients with schizophrenia. The accessibility model of FOK applies to patients with schizophrenia, and it is important to determine what occurs in other memory-impaired populations.

Predictive performance of ‘Diprifusor＇ TCI system in patients during upper abdominal surgery under propofol／fentanyl anesthesia

Objective: To evaluate the predictive performance of ‘Diprifusor‘ TCI (target-controlled infusion) system for its better application in clinical anesthesia. Methods: The predictive performance of a ‘Diprifusor‘ TCI system was investigated in 27 Chinese patients (16 males and 11 females) during upper abdominal surgery under total intravenous anesthesia (TIVA) with propofol/fentanyl. Measured arterial propofol concentrations were compared with the values predicted by the TCI infusion system.Performance was determined by the median performance error (MDPE), the median absolute performance error (MDAPE), the divergence (the percentage change of the absolute PE with time), and the wobble (the median absolute deviation of each PE from the MDPE). Results: The median (range) values of 14.9% (-21.6%～42.9%) for MDPE, 23.3% (6.9%～62.5%) for MDAPE, -1.9% h^-1(-32.7%～23.0% h^-1) for divergence, and 18.9% (4.2%～59.6%) for wobble were obtained from 227 samples from all patients.For the studied population, the PE did not increase with time but with increasing target propofol concentration, particularly following induction. Conclusions: The control of depth of anaesthesia was good in all patients undergoing upper abdominal surgical operation and the predictive performance of the ‘Diprifusor‘ target controlled infusion system was considered acceptable for clinical purposes. But the relatively bigger wobble showed that the pharmacokinetic model is not so suitable and requires improvement.
