汉语儿童英语口语词汇与阅读学习的关系

以120名四、五年级小学儿童为被试,探讨汉语儿童英语口语词汇与阅读学习的关系,并检验了英语语音意识在其中的中介作用。结果表明:(1)汉语儿童的英语口语词汇与阅读学习之间存在密切关系。控制一般认知能力和母语口语词汇的影响后,英语口语词汇对阅读学习仍具有显著的预测作用。其中,英语口语词汇产生对于英语单词认读的预测作用更重要,英语口语词汇理解则对英语单词理解的预测作用更重要。(2)英语口语词汇产生既可以直接作用于英语单词认读、理解和假词拼读,也部分通过英语语音意识的中介间接作用于英语阅读;英语口语词汇理解对英语单词理解也具有直接作用,并部分地通过英语语音意识的中介发挥间接作用     

现代医学模式与口腔修复设计

现代医学模式要求口腔修复在恢复患者口腔正常生理功能的基础上 ,还要满足患者心理的需要。口腔修复设计在口腔修复过程中起着至关重要的作用。口腔修复医生必须综合考虑口腔修复设计的各个要素 ,包括患者因素、医疗机构因素、医务人员因素 ,并正确处理这些要素之间的关系 ,才能为患者做出修复体的最佳设计     

The Effect of Parental Stress on the Oral Health of Children

Purpose: Examine the hypothesis that parenting stress was associated with poorer oral health in children. Methods: Ninety primary care-givers of children aged 5–12 years seen for routine dental visits completed the Parenting Stress Index (PSI) and demographic measures. The child's oral health was assessed by the number of decayed, filled, and missing teeth, and by the difference between recommended and actual times for return visits. Results: Lower levels of care-giver age, education, and Child Domain scores on the PSI predicted poorer dental health. Older children were significantly more likely to return on time for their next visit. Conclusions: In this economically stressed sample, children whose parents rate them as easy to care for and children of younger and less well-educated parents were more likely to have poorer oral health. Research on a more diverse population would determine if the results from this study can be generalized to other populations.     

Experiences of the Risen Jesus: The Foundational Historical Issue in the Early Proclamation of the Resurrection

Abstract : That Jesus' disciples experienced what they believed were appearances of the risen Jesus after his death is generally conceded by the critical scholarly community. The nature of these experiences is the key component in recent historical discussions. Drawn from a survey of recent scholarly resurrection studies, and building upon agreed data, various reasons are given to establish the reality of the disciples' experiences. Three major responses to the cause of these experiences are also outlined. The chief goal of this essay is not to decide between these three positions, but to narrow the focus of the current discussion.     

小学儿童英语课堂学习焦虑发展及其与教师教育行为的关系

运用《外语课堂学习焦虑量表》和《教师教育行为问卷》对399名3～6年级小学儿童英语课堂学习焦虑及他们知觉到的英语教师的教育行为进行了考察。结果发现:(1)小学儿童英语课堂学习焦虑随年级升高而逐渐增长,五、六年级儿童在交际畏惧、考试焦虑、否定评价恐惧方面的得分都显著高于三、四年级儿童;(2)交际畏惧和考试焦虑是我国小学阶段儿童的主要焦虑类型;(3)在英语课堂学习焦虑的三个维度上,男女生差异均不显著;(4)教师的消极反应与评价、鼓励与帮助是预测学生英语课堂学习焦虑的重要变量。研究结果表明,学校、教师和家长应重点关注高年级学生的课堂学习焦虑情况,加强情感疏导,并且教师要多给予学生积极的评价,有助于降低学生的课堂焦虑情绪。     

口腔颌面部鳞状细胞癌的综合序列治疗

口腔颌面部鳞状细胞癌(鳞癌)在头颈部肿瘤的发病和治疗中占有重要地位,综合序列治疗的概念和理论逐渐成为口腔颌面部鳞癌治疗的指导原则。本文对口腔颌面部鳞癌综合序列治疗所包含的手术治疗、放射治疗、化学治疗及生物治疗从临床治疗策略上进行分析、讨论,以期促进口腔颌面部鳞癌综合序列治疗原则在临床获得更好地应用。     

EFFECTS OF CONTINGENT REWARD AND INSTRUCTION ON ORAL READING PERFORMANCE AT DIFFERING LEVELS OF PASSAGE DIFFICULTY

This study examined the effects of reinforcement contingencies designed to increase the performance of existing reading skills as well as the effects of instruction—modeling and practice—designed to increase skill level for oral reading fluency across three levels of reading materials. Results showed that a combination of contingencies, modeling, and practice was effective in producing substantial increases in reading fluency for all participants at their assigned grade levels. These results demonstrate one strategy for experimentally determining those instructional components that are required to increase oral reading rate.     

Ratio size and cocaine concentration effects on oral cocaine-reinforced behavior.

Monkeys were given a choice between cocaine solutions and water under concurrent fixed-ratio reinforcement schedules. The operant response was spout contact. Six rhesus monkeys served as subjects. The cocaine concentration was varied from 0.0125 to 0.8 mg/ml, and the fixed-ratio value was varied from 8 to 128. Cocaine maintained higher response rates than did water over a wide range of conditions. Response rate and number of cocaine deliveries per session were inverted U-shaped functions of concentration. These functions were shifted to the right as the fixed ratio was increased. The number of cocaine deliveries was more persistent as fixed-ratio value was increased when the unit dose was larger rather than smaller. Cocaine consumption was analyzed as a function of unit price (fixed-ratio value divided by cocaine concentration), and unit price accounted for between 77% and 92% of the variance in cocaine consumption for individual monkeys. The current data support the claim that a drug's reinforcing effects increase directly with dose and underscore the need to gather parametric data when examining the effects of experimental manipulations on a drug-reinforced baseline.     

Oral drug self-administration in rhesus monkeys: interactions between drug amount and fixed-ratio size.

During daily 3-hr sessions, 5 rhesus monkeys drank drug solutions and water that were concurrently available. The drug solutions were: 1 milligram per milliliter (mg/mL) pentobarbital (2 monkeys), 1 mg/mL pentobarbital plus 0.5% ethanol (1 monkey), 1 mg/mL pentobarbital plus 1% ethanol (1 monkey), and 8% ethanol (1 monkey). The drug solution and water were available under identical two-component tandem fixed-ratio continuous-reinforcement N schedules. Two variables were manipulated: the size of the fixed-ratio component and the number of liquid deliveries (N) in the second component. Deliveries of the drug solution maintained higher rates of responding than did deliveries of the drug vehicle, water. The number of drug deliveries per session increased with increases in the number of deliveries per fixed ratio and decreased with increases in fixed-ratio size. Analysis of the results in terms of the proportion of deliveries to responses showed that the number of drug deliveries per session was directly related to the size of this quotient. Finally, when fixed-ratio size was repeatedly doubled, the following orderly relationship emerged: The greater the number of available drug deliveries per fixed ratio, the less was the percent decrease in the number of fixed ratios completed per session. It was concluded that increases in the number of liquid deliveries per fixed ratio resulted in increases in reinforcing efficacy.
