1932年《铁道法》形成的历史路径及其实施阻力

1932年中国历史上第一部铁路基本法——《铁道法》正式颁布。《铁道法》的诞生,既迎合了近代国人对铁路国有化的产业发展路径,也符合了铁路法制由简至繁、由缺至全的演进路径。《铁道法》是国民政府推行铁路产业政策的根本性立法,但在实施过程中受到了阻力,在不断的外耗与内耗中效力有限。     

汉晋时期的金玉带扣

上海博物馆的白玉龙纹鲜卑头的形制起源于北方游牧民族的青铜牌饰,工艺上仿制同时期的金银器,同时采用了中原汉民族喜爱的玉料和纹样。汉晋时期金玉带扣的外形经历了由长方形到前椭后方形的转变;同时,这一时期金玉带扣的材料、制作工艺及设计上也反映了胡汉文化的交流与融合。     

五帝时代(距今6-4千年)中国的气候

历史学研究表明,古代文献如《史记》记载的五帝:黄帝、颛顼、帝喾、唐尧、虞舜,可能应该视为一个时代,而不局限于五个人。获得较多支持的观点是:这个时代约在6-4kaBP,而且也不限于华夏集团,至少还包括东夷集团、苗蛮集团等。因此,从地望上讲,也不限于中原地区,还包括东部沿海及长江中游。考古学研究表明,6-4kaBP正是新石器时代晚期,后期可称为铜石并用时代。从考古文化来看,中原地区为仰韶文化中、晚期到龙山文化。东部地区为大汶口文化及(山东)龙山文化。其中在3500BC是仰韶文化中、晚期的交界,以及大汶口文化早、中期的交界。环境考古研究表明,6-4kaBP是一个由湿润气候向干旱气候转变的过渡时期。特别6.0-5.6kaBP有湿润气候的证据。4kaBP前后则明显进入晚全新世的干旱期,在此期间还包括5.5kaBP和4.2-4.0kaBP两次气候突变。现代气候资料及模拟研究表明,由早、中全新世的湿润气候向晚全新世的干旱气候转变的主要原因为岁差变化。但是,5.5kaBP及4.2-4.0kaBP的两次冷干气候突变,则可能与热盐环流的突然减弱有关,而热盐环流减弱可能是太阳活动减弱的结果。     

国共第三次“围剿”与反“围剿”探微

1931年国共在中央苏区展开的第三次“围剿”与反“围剿”,开场和结局都颇具戏剧性,整个“围剿”、反“围剿”进程,直接受制于国内外形势的变化。在国共两大主角的角力过程中,宁粤冲突和九一八事变,某种程度上成为国共武力斗争的搅局者。事实上,1930年代前后,国共之间的许多故事,都可以看到如是因素的介入,国共两大力量之外的“第三者”,为历史的走向增添了更多的变数。     

经济史:经济学方法与历史实证主义——答倪玉平先生

在拙著《民生与家计:清初至民国时期江南居民的消费》①一书的后记中,笔者曾坦承,这本书肯定仍存在很多问题,我全不敢奢望它的出版真能‘填补空白’或者‘解决’这个疑难课题,倒是在内心准备它成为进一步研究的批评标靶(第419页),这是笔者的真实想法。一项学术成果的问世,自然希望能为相关研究的整体进步作出贡献,并引起学术界对相关课题研究关注度的提升,无

Evidence for a Neolithic Age fire-irrigation paddy cultivation system in the lower Yangtze River Delta,China

Establishing stable cropping systems was vital in antiquity, assuring certain yields and enabling ancient people to settle, thus possibly causing various modern food habits and culture to form around the world, especially in cereal-cultivation-dominated countries. China, one of the most famous ancient agricultural countries, has a long history of rice planting, and the fire-irrigation paddy cultivation system is prevalent in the lower Yangtze region, which is considered a rice domestication center. However, its origin and cultivation pattern remain unclear. We studied a famous agricultural vestige, the Chuodun site, involved in rice planting in the lower Yangtze River Delta in eastern China, during the Neolithic Age. Clear evidence from archaeology, paleobiology, pedology and biogeochemistry suggest both that the rice fire-irrigation cultivation system formed during the Neolithic Age and that ancient peoples lived there steadily. Under this extensive cultivation system, soil structures and properties changed significantly; in particular, it left more black carbon in the soil and increased the organic carbon soil stability, which can be used to reconstruct prehistoric environments. Meanwhile, the prevalent fire-irrigation paddy cultivation system used by farmers in this area, though for a different purpose than ancient people, may be inherited from the Neolithic Age.     

The oldest root-eating beetle from the Middle Jurassic of China (Coleoptera,Monotomidae)

Cai, C.-Y., ?lipiński, A. & Huang, D.-Y., 31.3.2015. The oldest root-eating beetle from the Middle Jurassic of China (Coleoptera, Monotomidae). Alcheringa 39,488–493. ISSN 0311-5518.

Jurorhizophagus alienus gen. et sp. nov., a new fossil root-eating beetle, is described and figured based on an exceptionally well-preserved impression fossil from the Middle Jurassic Daohugou beds (ca 165 Ma), Inner Mongolia, northeastern China. It represents the earliest fossil Monotomidae known to date. Jurorhizophagus can not be assigned to either of two subfamilies Monotominae or Rhizophaginae based on the unique combination of many unusual characters, including an 11-segmented antenna with a 3-segmented club, the presence of a distinct frontoclypeal suture and transverse pronotum with a median longitudinal groove. The discovery of a new genus from the Middle Jurassic highlights the antiquity of Monotomidae and provides new information about the phylogenetic relationships between Monotomidae and its allied families.
