彩虹两头有我的家

三年前在县城买了一套商品房,妻女欣喜有了属于三个人的家,因为妻子和女儿邀请各自的朋友同学到家玩时喜欢说:我们家是二号楼三单元二楼。然而说到家,我一说就说的是离县城二十多公里,坐落在叫泽林的一条山沟沟里的那座黄土小院。 两居室的单元房比泥抹的农家小院有它的方便和舒适,我努力与这钢筋做架红砖做墙的建筑物进行着感情上的沟通,比如我用一些花草打扮它,在各个房     

Diagenesis in bone and enamel apatite carbonate; the potential of density separation to assess the original composition

This paper presents a new approach to the isotopic measurement of diagenetically altered archaeological bone apatite carbonate. We describe how the existing differential dissolution method may be combined with a new approach to remove diagenetically reformed material on the basis of its greater specific gravity. We show that heavier, more diagenetically altered fraction has a higher (altered) δ¹³C and also increased crystallinity within one individual. In addition, we proposed one potential tool to check the validity of bone carbonate by comparing bone collagen, enamel carbonate and bone carbonate values of δ¹³C and radiocarbon content from the same individual. In the case of Danebury cattle, we estimated the biogenic δ¹³C_apa value for DC83 and DC89, although it is still difficult to overcome diagenesis in order to meet the expected value, which is shown to be 1.9‰ (DC83) and 3.5‰ (DC89).     

从汉代铜镜纹饰看圆规在制图中的应用

通过对汉代的内向连弧纹镜的研究后发现,这种纹饰是古人用圆规分出的等分。进而对四神博局镜的背纹进行研究后发现,四神博局镜背纹中的几何纹饰也全部是采用圆规及直尺经过精心绘制而成。直至今日还可以看到,四神博局镜背纹中的几何纹饰,大都在某两条线的相交点上。从而说明,汉代的先民已具有了一定的机械制图水平。     

二十世纪《淮南子》研究

《淮南子》内容丰富,体系庞大,20 世纪的学人从各个方面对其展开了不同层次的研究,取得了丰硕的成果。但是从学术史的角度对其进行一次系统的梳理,在学术界没有引起足够的重视。因此本文尝试从具体的史料分析和归纳总结中,客观地展现出《淮南子》研究的时代特色和鲜明的自身特点来,希望为未来《淮南子》的研究寻找新的视野、开拓更宽广的学术平台。

Human mummified brain from a medieval tomb with lime‐soil mixture barrier of the Joseon Dynasty,Korea

Although all of the Korean medieval mummies found up to the present time have shown relatively well‐preserved brains, relevant biomedical information has been difficult to acquire owing to the obstacles to obtaining permission to conduct invasive investigations. However, recently we were able to secure permission to investigate, through various forms of examination including dissection, a well‐preserved brain found in a lime‐soil mixture barrier (LSMB) tomb in Yongin, Korea, because the remains found within the tomb were mostly skeletal. As in the cases of mummified brains from tombs found in other countries, the current Yongin case showed well‐preserved grey and white matter within well demarcated brain lobes, on which sulci and gyri could be identified. On histological examination, we found that the remaining brain tissue was composed mainly of lipids, which seems to correspond to the preserved myelin sheath. The present paper is the first report on the general preservation status of a mummified brain found in Korea. Moreover, because mummified brains are found quite frequently in LSMB medieval tombs, this study could provide a good basis upon which further such palaeo‐neuropathological studies can be progressed.

开放参观对莫高窟洞窟微环境的影响

洞窟微环境相对湿度是影响壁画保存的关键因素,为了解开放参观对莫高窟洞窟相对湿度的影响,本研究选择莫高窟南区四个相似洞窟进行长达10年(2004~2013年)的定期监测,对比分析了开放洞窟和关闭洞窟其相对湿度的变化情况。结果表明:开放洞窟相对湿度在开放时段波动频率与游客参观频次正相关,发生降雨时开放洞窟相对湿度迅速上升,关闭洞窟可有效阻隔窟外相对湿度波动的影响。开放洞窟在参观量大的旅游旺季,其相对湿度月极大值、日较差月均值以及日极大值超过60%的频次均明显高于关闭洞窟。将开放洞窟关闭,关闭洞窟开放后,其相对湿度呈相反规律变化。开放参观会导致洞窟相对湿度水平显著升高,日波动幅度明显增大,从而增加壁画劣化风险。这些结论可为洞窟的预防性管理和风险评估提供科学依据。     

For love or money? Assessing outcomes from direct public investment in film

ABSTRACT

This study examines Australian domestic film performance under two distinct policy regimes with respect to direct investment strategy. In particular, we contrast film performance under two public funding agencies with noted differences in (i) the number of films financed annually, (ii) the average (and maximum) funding per film, and (iii) the involvement of an expert review panel in funding decisions. In addition to box office returns, we consider performance benchmarks related to major film festival screenings, nominations and awards; critical acclaim based on IMDb user and critic reviews; and whether or not the film received a release in the major UK and/or US markets. Finally, we exploit a subset of our data where a ‘two-door’ policy was used for investment decisions that allows us to reflect on our more general results.
