高血压脑出血的治疗策略

高血压脑出血（hypertensive intracerebral hemorrhage,HICH）是一种高发病率、高致残率和高致死率的全球性疾病,一直是神经内、外科治疗的重点和难点。迄今,国际上缺乏对HICH的规范治疗方案,传统方法主要有内科药物和外科手术治疗。本文试图从哲学和临床的角度探讨HICH的治疗策略。     

特殊人群结核病的流行病学调查

为了了解某监狱犯人中结核病的患病及结核菌耐药情况,为防治提供依据,采用痰检和结核菌素试验的方式对研究对象进行普查,结核分枝杆菌采用罗氏培养,药敏试验采用比例法。结果显示,PPD试验总阳性率为60．54％。痰检发现24例患者,涂阳患病率为898．54／10万。培养菌株总耐药率为95．83％,其中初治耐药率、复治耐药率和多重耐药率分别为87．5％,100％和73．91％。提示该特殊人群结核病患病率高于一般人群。     

干扰素治疗慢性乙型肝炎管理策略初探

在慢性乙肝抗病毒治疗中干扰素作为一线治疗取得了一定的疗效。在治疗过程中通过选择合适的慢性乙肝患者、监测疗效、确立个体化的疗程和剂量、及时监测不良反应和恰当的处理和最大限度的提高患者的依从性可使干扰素的疗效达到最大化。     

Use of samples differing markedly in salience may encourage use of a single-code/default strategy in matching-to-sample in pigeons

To test the hypothesis that pigeons will only code the more salient sample when samples differ markedly in salience, pigeons were trained with samples consisting of a 2-s presentation of food (highly salient sample) and an 8-s presentation of keylight (less salient sample). During retention testing, pigeons tended to respond at longer delays as if an 8-s keylight sample had been presented. This finding is consistent with use of a single-code/default strategy in which only the 2-s food sample was coded and the comparison associated with an 8-s keylight sample was selected by default in the absence of memory for the salient 2-s food sample. Hence, a marked difference in sample salience appears to encourage use of a single-code/default strategy.     

英语文章阅读过程中的文章标记效应研究

该研究通过三个实验探讨高职生英语阅读的文章标记效应。实验一探讨文章标记对阅读英语长、短文章的影响,结果发现文章标记对英语长文章主题信息保持的促进作用大于对英语短文章主题信息的促进作用。实验二以EyelinkⅡ型眼动仪为工具,考察被试阅读有、无标记文章的主题句的眼动模式的差异,结果发现被试阅读这两类主题句的眼动模式存在显著差异。实验三考察对被试进行文章结构策略训练对文章标记效应的影响,结果发现训练促进了被试对无标记英语长文章主题信息的保持,研究结果支持策略转换假设。     

无意识元认知调控下的策略转换

通过两位数乘法算式答案判别任务研究无意识元认知调控下策略转换的的认知加工特征。整个算式答案判别任务分为两种策略使用情境：一种为只可以使用尾数策略的任务情境;另一种为既可以使用尾数策略,又可以使用奇偶策略的任务情境。实验结果表明：1）无意识元认知具有高选择性、高效性和高潜力,能在策略使用情境转变之后,快速察觉并选择使用更为简单、高效的奇偶策略;2）尾数策略使用的强大思维定势阻止奇偶策略的意识化,致使绝大多数被试未能发现任务情境的变化而在内隐状态下使用了奇偶策略;3）策略在内隐或外显状态下使用具有同等效力,策略内隐使用具有高效性和高潜力。     

THE EFFECTS OF RESPONSE CARDS ON STUDENT AND TEACHER BEHAVIOR DURING VOCABULARY INSTRUCTION

The use of response cards during whole‐class English vocabulary instruction was evaluated. Five low‐participating students were observed during hand‐raising conditions and response‐card conditions to observe the effects of response cards on student responding and test scores and teacher questions and feedback. Responding and test scores were higher for all targeted students in the response‐card condition. The teacher asked a similar number of questions in both conditions; however, she provided more feedback in the response‐card condition.     

Generalizing Teaching Techniques from University to K-12 Classrooms: Teaching Preservice Teachers to Use What They Learn

Preservice teachers learn evidence-based practices in university classrooms but often fail to use them later on in their own K-12 classrooms. The problem may be a missing link in teacher preparation, i.e., failure to teach preservice teachers to generalize newly acquired techniques. Two experiments using multiple baseline designs across participants assessed effectiveness of a model to promote generalization and maintenance of a specific teaching skill. In Experiment 1, preservice teachers’ maintenance of behavior deteriorated from practicum to student teaching when intervention consisted of training to criteria alone. When a programming for generalization component (program common stimuli) was added to the intervention, teachers in Experiment 2 generalized and maintained behavior across settings (student teaching to own classrooms) at a higher average than occurred during intervention.     

The Challenge-and-Response Model of Normal Anxiety

This article attempts to provide a conceptual framework placing anxiety in a personal growth perspective. The authors first discuss two different theories of anxiety, review some structural models of anxiety, and stress that anxiety should be studied as a certain kind of relation or interaction between the subject and her stimuli. Then a challenge-and-response model of normal anxiety of its cognitive components is established, which sorts anxiety into heteronomous one and autonomic one, and supposes that heteronomous anxiety includes two dimensions: the fall between the level of external challenge and the level of self challenge, and the importance of the external challenge. Some related evidences for the preceding hypothesis are examined, and then compared with related models. Finally, based on the model, a valid coping strategy of anxiety was put forward, from which the mechanism of normal coping style of anxiety in daily life can be well understood.     

简算策略教学提高小学四年级儿童的计算水平及延迟效应

采用3组平衡组实验设计对小学四年级171名学生进行教学实验,两组实验班学生分别采用讲授式和探究式教学方法进行简算策略计算教学,对照班教师自主进行计算教学。结果揭示：通过专门开设简算策略教学训练课,实验班学生的的计算成绩、计算速度和计算兴趣显著高于对照班学生;实验班的延迟提示与不提示测验无显著差异,未出现策略“利用性缺陷”现象;讲授式和探究式教学方法进行策略教学的效果无明显差异。本研究表明：专门开设策略训练课能提高学生的计算水平和学习兴趣,是有效的和必要的;只要教学方法得当,策略“利用性缺陷”可以避免
