Early Childhood Behavioral Inhibition and Social and School Adjustment in Chinese Children: A 5‐Year Longitudinal Study

This study examined relations between early behavioral inhibition and social and school outcomes in Chinese children (N = 200). Data on behavioral inhibition were collected from a sample of 2‐year‐olds in China. Follow‐up data on social behaviors, peer relationships, and school performance were collected from multiple sources at 7 years of age. Behavioral inhibition was found to be positively associated with later cooperative behavior, peer liking, perceived social integration, positive school attitudes, and school competence, and negatively associated with later learning problems. Highly inhibited toddlers were generally better adjusted than others in social and school areas in middle childhood. The results indicate the distinct functional meaning of behavioral inhibition in Chinese children from a developmental perspective.

浅谈杜十娘人物形象的悲剧性

杜十娘是我国文学史上为数不多的经典悲剧形象之一。虽是风尘女子,但她的勇敢刚烈、执着善良、恩怨分明却令很多读者为之震撼。在《杜十娘怒沉百宝箱》中对杜十娘爱情悲剧的描写,可谓"极摹人情世态之歧,备写悲欢离合之致",本文将分别从其身世经历、性格、爱情及理想几方面对其悲剧性加以分析。     

Enhancing query translation with relevance feedback in translingual information retrieval

As an effective technique for improving retrieval effectiveness, relevance feedback (RF) has been widely studied in both monolingual and translingual information retrieval (TLIR). The studies of RF in TLIR have been focused on query expansion (QE), in which queries are reformulated before and/or after they are translated. However, RF in TLIR actually not only can help select better query terms, but also can enhance query translation by adjusting translation probabilities and even resolving some out-of-vocabulary terms. In this paper, we propose a novel relevance feedback method called translation enhancement (TE), which uses the extracted translation relationships from relevant documents to revise the translation probabilities of query terms and to identify extra available translation alternatives so that the translated queries are more tuned to the current search. We studied TE using pseudo-relevance feedback (PRF) and interactive relevance feedback (IRF). Our results show that TE can significantly improve TLIR with both types of relevance feedback methods, and that the improvement is comparable to that of query expansion. More importantly, the effects of translation enhancement and query expansion are complementary. Their integration can produce further improvement, and makes TLIR more robust for a variety of queries.     

如何提高俄语口语教学

口语是外语教学的重要组成部分.口语不过关,就谈不上全面掌握外语.然而在我国的俄语教学中,口语的应用能力几乎被忽视,这种教学模式培养出来的人才语言应用能力不高,不适应当今社会对俄语复合型人才的要求.而本文主要针对如何提高俄语口语教学提出一些个人见解.

中国县域地面坡谱分级及其与人口分布的关系

针对平均坡度指标难以稳健描述地面坡谱特征的问题,提出一种基于频率累加分位归并的坡谱分级方法。作为验证,运用数字高程模型数据将全国县域分为5个坡级,借助2000年和2020年人口普查数据分析了坡级与人口分布的关系。结果发现：（1）所提出的分级方法包含频率累加曲线的构建、基于分位数的参考曲线生成、基于相似度的类型归并3个关键步骤,由此得到的全国县域坡级划分方案具备稳健坡度梯度性、宏观空间连片性以及清晰地学含义。（2）全国县域人口数量总体保持随坡级升高而波动式缩小的特征,且二者间呈现明显的线性负相关关系,线性拟合R2从2000年的0.761上升到了2020年的0.845,20年间人口总数变化量与坡级的线性拟合R2达0.963;人口密度的极端值对其自身的坡级分布有较大影响,当剔除人口密度小于20人/km2和大于2000人/km2的区域后,两个分析年份全国县域人口密度均稳健保持着随坡级升高而线性减小（R2> 0.985）。本文为稳健表达如坡度等环境梯度提供了一种新的可行分级方法,并深化了对中国县域人口分布与坡度关系的认识。
