先秦诸子语言使用的层次问题

阅读先秦诸子,发现其对语言的态度不尽相同。分析其不同,发现其关注点不同而使用的语言也有不同的层次。明白语言使用的层次性,至少对训诂、阐释、语文教学等有意义。     

安徽省旅游业对经济增长拉动效应的实证研究——基于二维度与三指标的探讨

通过构建旅游业依存度、贡献率和拉动率三个指标,从时间和空间两个维度,本文探讨了安徽省旅游业对经济增长的拉动效应。结果表明,安徽省旅游业对经济增长的拉动效应逐渐加大;在中部六省中,安徽省旅游业拉动效应并不突出;在省域内部,各地市旅游业对经济增长拉动效应的空间非均衡现象较突出,且南强北弱的空间格局与旅游资源在等级上南高北低、景区在空间上“南热、中温、北冷”现状具有很强的共轭性。三个指标均具有相对性,当计算拉动效应时,应同时考虑区域尺度的因素。     

独乐寺观音阁辽代十一面观音像的材质分析

独乐寺观音阁内十一面观音像保存至今,泥胎存在裂隙、空鼓、脱落等病害。利用超景深三维显微镜、X射线衍射分析(XRD)、激光粒度分布仪等对观音像泥胎进行了材质分析。通过控制砂、纤维含量,分析泥塑试样的收缩性,并探索纤维含量对泥胎收缩性的影响规律。结果表明:观音像泥胎的制作原料取自当地,其中土颗粒粒径多在5~70 μm之间,约占总量的79.5%;主要矿物成分为石英和伊利石,还有部分钠长石和钾长石,以及少量的高岭石。粗泥层含砂量约为35%,麦草(麦秆及麦壳混合物)含量约6%~9%,长度大多在2 cm以下;细泥层含砂量约为30%,麻丝含量约2.1%,长度大多集中在2 cm。麦草和麻丝的加入对泥胎的收缩均能起到抑制作用。随着麦草含量的增加,抑制作用呈现先增大后减小的趋势,掺和6%的麦草抑制作用最好;添加麻丝可使试样的最终线缩率显著减小,但麻丝的多少对线缩率的减小幅度影响不大。观音像泥胎的原纤维配比就有很好的抑制收缩效果。本次研究获得了十一面观音像泥胎的材料组成信息,得出了纤维占比对泥胎收缩性的影响,为十一面观音像的修复与保护提供了参考。     

国际油价波动对日本经济均衡的影响

2005年以来,国际原油价格剧烈震荡,除实体经济层面的供求因素外,能源作为金融商品的虚拟经济属性被放大,预期、投机、突发事件、汇率波动因素等都可能成为引燃油价波动的导火索。新的油价变动特点,使日本更加难以保持经济的内外均衡。从内部看,企业、行业间的收入分配效应分散了油价上涨的通货膨胀效果,具有技术垄断优势、善于利用金融工具避险及有效采取能源分散化和节能措施的企业与行业受油价波动的冲击更小。从外部看,进口成本增加和出口成本转嫁不完全引起了日本贸易条件恶化;石油美元通过贸易渠道和资本渠道的回流,对日本的国际收支产生一定影响;日元升值因素一定程度上缓和了高油价的冲击。日本政府、企业、居民的不懈努力创造了日本经济超低能耗的奇迹,这个奇迹将日本抵御油价波动的能力变成现实。．     

The role of waterways in the spread of the Neolithic

The causes and implications of the regional variations in the spread of the incipient agriculture in Europe remain poorly understood. We use population dynamics models to study the dispersal of the Neolithic in Europe from a localised area in the Near East, solving the two-dimensional reaction-diffusion equation on a spherical surface. We focus on the role of major river paths and coastlines in the advance of farming, to model the rapid advances of the Linear Pottery (LBK) and the Impressed Ware traditions along the Danube–Rhine corridor and the Mediterranean coastline, respectively. We argue that the random walk of individuals, which results in diffusion of the population, can be anisotropic in those areas and hence lead to an effective advection. The standard reaction-diffusion equation is thus supplemented with an advection term, confined to the proximity of major rivers and coastlines. The model allows for the spatial variation in both the human mobility (diffusivity) and the carrying capacity, reflecting the local altitude and latitude. This approach can easily be generalised to include other environmental factors, such as the bioproductivity of landscapes. Our model successfully accounts for the regional variations in the spread of the Neolithic, consistent with the radiocarbon data, and reproduces a time delay in the spread of farming to the Eastern Europe, Britain and Scandinavia.     

1952～1954年湖北省农村私人借贷的历史考察

私人借贷在全国解放前一直是农村金融体系的重要组成部分.解放以后,从1952～1954年湖北省的调查材料来看,由于经济落后、家庭经济弱小、缺乏完善的社会保障和现代金融体系等原因,农村的私人借贷虽受到抑制但仍有一定的发展,与解放以前相比,这一时期的私人借贷形式较为简化,利率较低,功能上也以互助互济为主.国家银行业务在农村的延伸和农村信用社等现代金融组织的发展在一定程度上压缩了私人借贷的空间,但并不能完全替代私人借贷.     

江陵天星观一号楚墓出土饱水木漆器F455中细菌对硬松木的腐蚀研究

研究木质文物中的细菌对木材腐蚀性影响,筛选防腐剂抑制腐蚀性强细菌的腐蚀作用,是延长木质文物保存期的一种有效的生物保护措施。为研究饱水木漆器F455及其水环境中细菌的种类,以及对木材的腐蚀程度,采用16S rRNA基因序列分析方法及生理生化试验,对饱水木漆器F455及水环境中细菌进行鉴定,并选取典型菌按5×10~8个/瓶菌量接种马尾松心材(悬于无菌自来水中),37℃培养120d,测试木材的损失率。结果发现,从F455文物挑选的32株细菌中,有29株菌鉴定为芽孢杆菌属(Bacillus),为优势菌属,其余为短杆菌属(Brevibacterium)、短波单胞菌属(Brevundimonas)和产碱杆菌属(Alcaligenes)各1株。水样样品中细菌菌属较F455文物样品中丰富,27株菌有9个属,其中短杆菌属(Brevibacterium)有9株,为优势菌属,其余交替赤细菌属(Altererythrobacter)有5株,短波单胞菌属(Brevundimonas)有4株,产碱杆菌属(Alcaligenes)有3株,黄杆菌属(Flavobacterium)有2株,芽孢杆菌属(Bacillus sp.)、白色杆菌属(Leucobacter)、类芽孢杆菌属(Paenibacillus)、苍白杆菌属(Ochrobactrum)各1株。从2种样品材料的分离菌中共挑选出14株典型菌进行木块腐蚀试验,与对照组比较,其中有9株菌差异极显著。说明这些菌对马尾松木材有一定的腐蚀作用,但是腐蚀率非常低,最高仅1.56%。表明这些细菌对试验木材马尾松腐蚀并不严重。该研究分析了饱水木漆器长期保存在水槽中细菌对木漆器的影响,丰富了饱水木漆器文物生物影响的理论依据。     

Mortality differences according to marital status among men and women in Kuwait

Higher mortality among unmarried persons compared with currently married ones has been reported in many previous studies. There is paucity of such studies in developing countries. We analysed the association between marital status and mortality in Kuwait, an oil-rich Gulf Muslim country. Data were obtained from the Public Authority for Civil Information that has maintained a linked record database of population characteristics with death notifications since 2005. Deaths during 2005–2010 were aggregated for the analysis. Age-specific death rates and standardized mortality ratios (SMRs) were calculated according to marital status (married, never married, divorced and widowed), age (15–49, 50–64 and 65+), gender, and nationality (Kuwaiti vs. non-Kuwaiti). Among Kuwaiti nationals, the SMRs for widowed, divorced, and never married were 1.75, 1.68 and 1.15 compared to the married. Higher mortality was found among unmarried men and women at almost all ages. These findings may be indicative of considerable public health problems such as higher disability and depression among the unmarried.     

Trends and Implications of Delayed and Non-Marriage in Korea

Korea has experienced marital transition since the 1920s, but recent data reveal rapid changes in marital behaviour and norms. Analysts usually relate these to the second fertility transition, fast growing gender equality, economic developments, and ideational changes, pointing to the necessity of understanding the process of change in marital behaviour in the context of societal transformation as well as demographic transition. With this background in mind, this paper constructs refined measures, such as age-specific first marriage rates and total first marriage rates, for different time periods and for different cohorts to present a clearer picture of marriage trends. The results are then examined in relation to various social and demographic factors, a procedure which provides an indirect check on the validity and usefulness of the method.     

Decomposing the crude divorce rate in five countries: Singapore,Taiwan, South Korea,the UK,and Australia

Over the past few decades, the level of divorce, measured by the crude divorce rate (CDR), has increased dramatically in both the East and the West, but has recently appeared to fall or level off in some countries. To investigate whether the recent decline or stabilisation of the CDRs reflects the real trends in divorce risk, a decomposition analysis was conducted on the changes in the CDRs over the past 20 years on two western and three East Asian countries, namely, the UK, Australia, Taiwan, South Korea, and Singapore. The following is observed: the decline in the CDRs of the UK and Australia in the 1990s, and of Taiwan and Korea in the 2000s, was mainly due to shrinkage in the proportion of the married population rather than any reduction in divorce risk; only Australia experienced a genuine reduction in divorce risk between 2001 and 2011; and the continuous increase of Singapore’s divorce level between 1990 and 2010 may be is an unintentional effect of the government’s marriage promotion policies. The shift in the population age structure, and more importantly, the drastic decline in marriage, has seriously distorted the CDRs, making them unreliable indicators for monitoring divorce trends.
