论蒋捷词的爱国与隐逸情怀

蒋捷是宋末元初词人,经历了宋元易代之际的巨大动荡,承受着国破家亡之痛、身世飘零之苦,用词记录下万千郁抑、悲慨、哀痛、愁怨、落寞与无奈,爱国情思蕴育其间,最终在山水风景、闲适生活中寻找到恬淡、悠然、平静的快乐,流露出其遗世独立、清逸高洁的节操。     

XXXIX.—The Hippoboscidæ (Diptera) recorded from Ceylon

Summary

The most profitable ways of collecting chalcids are discussed, namely by sweeping, suction sampler, beating, pyrethrum spray, rearing, Malaise traps, yellow pan traps, suction traps, pitfall traps and extraction from leaf litter or grass tussocks. Methods of preserving chalcids are also outlined, with particular emphasis on storing all unmounted material dry rather than in alcohol. The techniques of sweeping, card mounting specimens and slide preparation are described in detail.

陶渊明隐逸身形的背后--兼谈儒道人生观的消涨融合

陶渊明均以隐逸诗人的身形出现在大家面前,如对其人生经历、写作动机、人格本质等方面作较为深入地考查,我们发现在其隐逸身形的背后,是积极进取的人生态度.本文从儒道两派人生观的消涨融合,来探讨"陶渊明们"矛盾心理世界的原因.     

困而退隐--从散曲看元代知识分子的归隐现象

元代知识分子承受着汉民族"自我"位置的失落与传统知识分子"应有位置"的失落.这种困境,使得儒家个人传统价值观所造成的痛苦与道家逍遥避世所带来的心灵解脱在他们心中不断撞击,这种矛盾心理反映在文学作品中也就形成了元散曲"叹世归隐"的主题.     

Population dynamics and reproduction of the hermit crab Calcinus gaimardii (Anomura: Diogenidae) at Inhaca Island,southern Mozambique

The population dynamics and reproduction of Calcinus gaimardii were studied at Inhaca Island, southern Mozambique. Crabs were sampled monthly from January to December 2003 in order to assess abundance, size distribution, sex ratio, reproduction and juvenile recruitment. Calcinus gaimardii is sexually dimorphic in relation to size, with males reaching larger size than females. Sex ratios were female‐biased during most months of the study period. Females were more abundant in the intermediate size classes while males outnumbered females in the largest ones. Reproduction took place year‐round with peaks of breeding activity between August and October. Likewise, juvenile recruitment was continuous for both sexes with high intensity in winter (May and June). Egg number increased with female size.     

Larval development and emigration behaviour during sea-to-land transition of the land hermit crab Coenobita brevimanus Dana, 1852 (Crustacea: Decapoda: Anomura: Coenobitidae) under laboratory conditions

To determine the early life history of the land hermit crab Coenobita brevimanus Dana, 1852, larvae were cultured individually in the laboratory. The zoeal and the megalopal stages are described and illustrated. The larvae developed through four planktonic zoeal stages to the megalopal stage. The major differences in the zoeal characters between C. brevimanus and other described Coenobita species were found in the armature of the pleomeres, whereas the character of pleomeres of C. brevimanus zoeae is the same as that of the coconut crab Birgus latro, a different genus in the same family. Morphological similarity was also found in segmentations of antennules and antennae in megalopae between C. brevimanus and the coconut crab. Megalopae of C. brevimanus were cultured in containers holding seawater and a hard substrate. These crabs migrate from the sea to land after developing a habit of acquiring gastropod shells.     

“虚静”与六朝隐逸之风

六朝隐逸之风盛行与"虚静"内涵发展关系密切。中国隐逸文化本质是一种"静观的人生","虚静"是隐逸思想的重要文化符号。先秦时期"虚静"成为观照事物的方式,后逐渐向审美心理转化。延至两汉,由于性命学的发展,"虚静"作为修炼"心性"的方式之一,成为养生学的重要内容。六朝士人崇尚"虚静",归隐成风,根源在于长期的文化积淀和特殊的时代背景,例如生命意识的高涨,对个体价值的进一步认识,品藻人物以"虚静"为标尺、为旨趣的艺术审美的新构等,这些"合力"掀起了六朝隐逸的高峰,成为中国文化的一个特殊现象。     

陶渊明隐逸原因初探

对于陶渊明归隐的原因,历来众说纷纭,笔者认为这决非是他心甘情愿的。陶渊明的骨子里浸润着儒家入世的思想,只是混乱黑暗的时代、等级森严的门阀制度、率性任真的性格、因穷守节的心志,猛志干进的受挫,迫使他不得已选择了归隐山林这条人生路。
