Penn State Worry Questionnaire: structure and psychometric properties of the Chinese version

The Penn State Worry Questionnaire (PSWQ) is a measure of worry phenomena and has been demonstrated valid in cross-cultural populations. The present study examined the factor structure and psychometric properties of the Chinese version of PSWQ (Ch-PSWQ) in a Chinese college sample (n=1243). Exploratory factor analysis of the Ch-PSWQ revealed a two-factor solution (engagement of worry and absence of worry). Confirmatory factor analysis and model comparison supported that the model of one factor with method effect provided the best fit to the data. The Ch-PSWQ and its factors evidenced good internal consistency and both convergent and discriminate validity. The present study supports the opinion that the second factor of PSWQ not only contains the component of evaluating pathological worry, but also might represent other traits.     

论屈原思想的形成和渊源——兼论稷下学宫对屈原的影响

屈原是我国文学史和思想史上一位光耀千古、影响久远的伟人,屈原思想的形成是多方因素综合作用的结果。良好的家世给屈原以巨大的鼓舞和激励,莫敖子华、昭阳、淖滑等人的爱国思想和政治主张也深深影响了屈原的政治革新。屈原是联齐抗秦路线的坚定践行者,他曾三使齐国,到过稷下学宫;稷下学宫作为当时思想文化交流的中心,学术争鸣和思想交流的良机屈原不会与之失之交臂。

论霍布斯、洛克、卢梭人性论思想对其“自然状态”学说的影响

“自然状态”是霍布斯、洛克、卢梭的社会契约论的逻辑起点,是建立在其人性论基础之上.霍布斯是性恶论者,洛克是性善论者,卢梭是性非善非恶论者,不同的人性论思想对其“自然状态”的哲学基础、表现形式、内容描述、逻辑走向四个方面产生了不同的影响.     

秦墓出土铜带饰相关问题研究

目前出土的铜带饰仅仅出现在渭河流域的秦墓中,其时空分布与秦国的发展史相吻合。从秦与戎狄的战争、秦的数次迁都、秦墓中所见的诸多戎狄文化因素来看,在秦与周边戎狄部族长期的互相影响下,这种具有强烈戎狄风格的饰品在秦国获得了发展,并在一定程度上融入了秦人的生活。     

褚斌杰先生的中国古代文体及白居易研究

北京大学教授褚斌杰先生是著名学者、文学史家、教育家,他在五十多年学术生涯中,写下了大量的论文和著作,对中国古代文学研究和古代文学教育,特别是先秦两汉文学研究与教育做出了重要贡献.同时,褚先生的学术成就又是多方面的.本文试图对褚斌杰先生有关先秦两汉文学研究以外的中国古代文体研究、白居易研究等的贡献做一个简要的总结.     

浅析琵琶曲霸王卸甲

琵琶曲的分类上有文曲和武曲、大曲和小曲之分,《霸王卸甲》一曲在琵琶曲中属于武曲。但《霸王卸甲》一曲不仅表现了战争场面,更表现了乐曲主人翁项羽“悲”的情感色彩。全曲感人至深的音乐情感,令人难忘。文章是通过对琵琶曲《霸王卸甲》中段落结构、创作手法和演奏技巧的浅析,根据在乐曲发展过程中,音乐的发展和故事发展相对应的发展方式,探寻这首乐曲对故事悲情色彩的音乐情感的表达方法。     

评李陈玉之《楚词笺注》

李陈玉《楚词笺注》"自叙"所表达的主要意图是褒"笺"贬"注"。此书褒"笺",重视对作品进行层次分析,值得肯定,但其理论上矫枉过正,实践也并非成功。李氏贬"注",且书中有些"注"确也过于随意、偏激,但不少"注"独创一说,难能可贵。     

Going ‘to the Fountainhead’: Black American Athletes as Cultural Ambassadors in Africa, 1970–1971

During the Cold War, the State Department frequently employed prominent black athletes as cultural ambassadors in an attempt to defuse global criticism of racism in the USA. In the late 1960s, as many black American athletes identified increasingly with the “Black Power” movement, their personal motivations often clashed with State Department goals. In 1970, the black American tennis star Arthur Ashe, along with Stan Smith, conducted an extremely successful tour of six African nations. The following year, the State Department attempted to replicate that success by sending NBA stars Kareem Abdul-Jabbar and Oscar Robertson to Africa. Those players, for a variety of reasons, were less cooperative and effective than Ashe. The shortcomings of the Jabbar/Robertson tour contributed to a decline in the State Department's practice of utilising star black athletes as cultural diplomats.     

Effect of 6 weeks of endurance training on the lactate minimum speed

The aim of this study was to assess the sensitivity of the lactate minimum speed test to changes in endurance fitness resulting from a 6 week training intervention. Sixteen participants (mean +/- s :age 23 +/- 4 years;body mass 69.7 +/- 9.1 kg) completed 6 weeks of endurance training. Another eight participants (age 23 +/- 4 years; body mass 72.7 +/-12.5 kg) acted as non-training controls. Before and after the training intervention, all participants completed: (1) a standard multi-stage treadmill test for the assessment of VO 2max , running speed at the lactate threshold and running speed at a reference blood lactate concentration of 3 mmol.l -1 ; and (2) the lactate minimum speed test, which involved two supramaximal exercise bouts and an 8 min walking recovery period to increase blood lactate concentration before the completion of an incremental treadmill test. Additionally, a subgroup of eight participants from the training intervention completed a series of constant-speed runs for determination of running speed at the maximal lactate steady state. The test protocols were identical before and after the 6 week intervention. The control group showed no significant changes in VO 2max , running speed at the lactate threshold, running speed at a blood lactate concentration of 3 mmol.l -1 or the lactate minimum speed.In the training group, there was a significant increase in VO 2max (from 47.9 +/- 8.4 to 52.2 +/- 2.7 ml.kg -1 .min -1 ), running speed at the maximal lactate steady state (from 13.3 +/- 1.7 to 13.9 +/- 1.6 km.h -1 ), running speed at the lactate threshold (from 11.2 +/- 1.8 to 11.9 +/- 1.8 km.h -1 ) and running speed at a blood lactate concentration of 3 mmol.l -1 (from 12.5 +/- 2.2 to 13.2 +/- 2.1 km.h -1 ) (all P ? 0.05). Despite these clear improvements in aerobic fitness, there was no significant difference in lactate minimum speed after the training intervention (from 11.0 +/- 0.7 to 10.9 +/- 1.7 km.h -1 ). The results demonstrate that the lactate minimum speed,when assessed using the same exercise protocol before and after 6 weeks of aerobic exercise training, is not sensitive to changes in endurance capacity.
