人工巢箱下麻雀窝卵数和生长发育初探

2010年3～5月在人工巢箱条件下,对河池学院校园的麻雀繁殖生态进行了研究。收集的数据有麻雀的窝卵数、卵的特征值、雏鸟生长发育特征等。统计分析表明:麻雀4月初产卵,卵长径为18.85mm±0.98mm、短径为13.76 mm±0.54 mm、卵重为1.89 g±0.31 g、窝卵数3.33枚±1.00枚,育雏期15～18 d。雏鸟体重及外部器官的形态学参数可以用Logistic曲线方程很好地拟合,体重、翅长、跗跖、嘴峰长及18日龄前的尾长均呈"S"型。

Infant Proneness-to-Distress Temperament, Maternal Personality, and Mother-Infant Attachment: Associations and Goodness of Fit

66 mother-infant pairs were examined when the infants were 9 and 13 months. The purpose of this report was to examine relations between infant proneness-to-distress temperament, maternal personality characteristics, and mother-infant attachment. There were no main-effect relations between infant proneness-to-distress temperament as assessed at 9 months and infant attachment classification at 13 months. This was true whether security of attachment (A and C vs. B) or proposed temperament (A1-B2 vs. B3-C2) groupings of attachment classifications were examined. Infant proneness-to-distress temperament, however, was associated with maternal behavior and personality. Furthermore, security of attachment could be predicted by an interaction between maternal personality and infant proneness-to-distress. The importance of considering goodness-of-fit relations in predicting attachment security is discussed.

试论高校内部和谐权力话语关系的构建——基于对J省高校的调查研究

文章通过对J省高校内部权力运行情况调查,比照当下教育语境阐释高校内部三种权力话语:一是以行政管理人员为主的行政权力话语;二是以教学科研人员为主的学术权力话语;三是以学生为主的学生权力话语。三种权力话语的阐释,意在以权力话语理论为指导,突破以往的认知限制,促进三种权力话语的有效对话,以三权相互独立又相互制衡的大学治理理念,构建大学组织的和谐权力配置模式。     

Deaf college students' comprehension of relational language in arithmetic compare problems

In this study of deaf college students' performance solving compare word problems, relational statements were either consistent or inconsistent with the arithmetic operation required for the solutions. The results support the consistency hypothesis Lewis and Mayer (1987) proposed based on research with hearing students. That is, deaf students were more likely to miscomprehend a relational statement and commit a reversal error when the required arithmetic operation was inconsistent with the statement's relational term (e.g., having to add when the relational term was less than). Also, the reversal error effect with inconsistent word problems was magnified when the relational statement was a marked term (e.g., a negative adjective such as less than) rather than an unmarked term (e.g., a positive adjective such as more than). Reading ability levels of deaf students influenced their performance in a number of ways. As predicted, there was a decrease in goal-monitoring errors, multiple errors, and the number of problems left blank as the reading levels of students increased. Contrary to expectations, higher reading skills did not affect the frequency of reversal errors.
