Developmental patterns of school students' motivational‐ and cognitive‐metacognitive competencies

This study examined the metacognitive developmental patterns of Hong Kong school students. Students rated their own metacognitive competencies by responding to an inventory of six motivational‐ and cognitive‐metacognitive subscales. Results showed that students' metacognitive competencies decreased with age—from primary 4 (age 9) to secondary 5 (age 17)—with a sharp decline noticeable at the primary/secondary school transition. Age had a more powerful effect than gender on students' perception of their metacognitive competencies. This decreasing pattern of Hong Kong students' metacognitive competencies is contrary to the developmental trends found in Western countries. However, the comparatively high academic performance of Hong Kong students also suggests some different recommendations about student learning.     

论刘震云小说的荒诞书写及其局限——以《吃瓜时代的儿女们》和《我不是潘金莲》为例

重复作为刘震云小说的叙述模式,体现出作家对于人生荒诞感的认知。《吃瓜时代的儿女们》和《我不是潘金莲》是刘震云荒诞书写的代表作品,但小说人物存在符号化、简单化倾向和"想当然"意味,偏离了五四"人的文学"的传统。同时,小说结尾将主人公的悲剧置换为另一批人的喜剧,具有较为强烈的悲观主义色彩,降低了作品的思想启蒙力量。《吃瓜时代的儿女们》和《我不是潘金莲》两部小说体现出刘震云在运用西方文学资源本土化方面的不足之处,对于中国当代作家的创作,具有一定的启发意义。

A comparative study of error detection in discourse

A study of error detection in discourse is reported in which children 10 to 13 years old listened to set of expository texts read aloud, read the texts via a moving window simulated on a computer screen, or read them typed on paper. Occasional changes were introduced in the texts, resulting in illformedness at a semantic level, at a morphosyntactic level, or (in reading) at an orthographic level. The subjects were 278 Swedish 4th and 6th grade pupils. Analysis of d showed that all test groups performed above chance, that 6th grade children were better at the task, and that errors were easiest to detect while listening. By the same standard, detecting errors when reading was easier from hard copy. However, 4th graders detected both more othographic and morpho-syntactic errors when reading from the moving window, suggesting some advantage in presenting text to younger readers from left to right.     

新石器时代长江、黄河两大文化体系比较

我国新石器时代长江、黄河两大文化体系存在着地理环境、农作物与家畜品种、生产方式与生活方式的差异，房屋建筑、葬丧制度及宗教信仰的文化内涵截然不同。黄河文明祖先崇拜所构成的氏族团体奋斗精神，强化宗教权威崇拜所具有的内聚力，对外扩张的进取性，造成北方文化 旺盛的生命力；南方松散而缺乏向心力的氏族团体，自由随意、缺乏积极进取而保守的水稻文化，失去一种锐意进取精神，最终走向衰弱。中国文明在黄河流域产生也就不是偶然了。

陆小艺:一个另类的"女权主义者"——柳建伟《英雄时代》人物丛论之三

柳建伟的《英雄时代》塑造了各式各类的"英雄"形象,其中,陆小艺可谓别具一格,尤为"耀眼":她是一个相当另类的"女权主义者"——"权"的彻悟者、极端崇拜者、狂热追求者和"权"令智昏者;她是一个另类的"女权主义者",也是中国当代文学史上另类女性形象中的"这一个"。     

论建立基本养老保险个人账户基金市场化运营管理制度

文章论证了在基本养老保险个人账户做实的政策下，个人账户基金市场化运营的必要性和可行性，并提出了基金市场化运营的制度构想。认为，个人账户基金按市场的原则配置，追求社会平均收益率既是养老制度的内在要求，也是市场经济发展的外部要求；养老保险体制的发展及中国资本市场的发展为养老基金市场化运营提供了有利条件和难得的机遇。建议建立省级社会保障基金委员会作为个人账户受托人，并实行受托人决策下的、委托投资管理人进行的规范化、专业化、市场化运营的基金管理体制。     

Racial and ethnic variation of PSA in global population: Age specific reference intervals for serum prostate specific antigen in healthy South Indian males

The serum PSA is universally accepted as the useful and clinically relevant tumor marker for monitoring therapy and identifying early recurrence in patients of carcinoma prostate throughout the world. However, application of serum PSA is limited to screening for early adenocarcinoma prostate among males above fifty years of age. Serum PSA concentration varies from one population to another in different parts of the world. Many groups of workers have selected 4 ng/ml of serum PSA as upper limit of normal range without giving due consideration for age specific increase in serum PSA. There is no single report available on normal decade wise age specific reference intervals for serum PSA in Indian males. The present study is undertaken to establish age specific reference intervals in healthy Indian males from 20–89 years belonging to subpopulation of Andhra Pradesh from South India. Our results revealed lowest concentration of 95 percentile serum PSA in Indian males compared to other populations globally. Contrary to this, healthy Afro Americans were found to have highest concentration of serum PSA compared to all other populations.
