省级多维减贫经验:以青海省为例

多维减贫是指"以减少贫困人口为基础,缓解贫困问题的恶性发展及贫困问题的衍生影响,针对贫困的多个维度,如收入贫困、人类贫困、信息贫困及生态贫困等形成测定和监控系统,进行综合性防治,促进人类生存发展与自由。"本文以青海省为例,在省级层面对多维减贫进行必要性及可能性的分析,并在总结经验的基础上得出了指导实践的相对成熟的减贫新思想。     

乾隆前期直隶留养局的空间分布特点及原因分析

文章以同治《畿辅通志》为主要资料,对初创时期直隶留养局的空间分布进行探讨,揭示了其既普遍又不均衡的分布特点,并对形成该特点的原因进行了分析。指出行政命令的统一性是这一慈善组织普遍设立的主要原因,区域自然环境、自然灾害频繁程度、经济状况、人口密度、与交通线的关系以及地方官员的积极性等是影响其分布不均衡的因素。     

宋元之际四川主要城市地理分布格局演变探析

宋元战争之前,四川主要城市分布在四川西北部金牛道及其支线附近。宋元战争打破了四川主要城市原有地理分布格局,出于军事角度考虑,南宋将残存城市迁入山城之内,蒙元因之。山城中军民一体,是宋元之际四川城市地理格局演变的过渡形态。山城修建以江河为纲,增强了岷江—嘉陵江—长江水路的重要性,保存了四川残余的大部分城市资源。战后,山城保护的资源成为四川城市重建的重要基础,有力地促进了四川主要城市沿岷江—长江—嘉陵江水路分布于四川东南部地理新格局的形成。     

四川广汉龙居寺中殿建筑热湿环境特征研究

为了解广汉龙居寺中殿建筑热湿环境特征,采用基于物联网技术的环境温湿度监测系统对建筑空间温度和相对湿度进行监测,分析建筑空间温湿度时空变化规律,评估建筑热湿环境特征,探讨热湿环境对文物保存的影响。结果表明,该建筑对外界环境温湿度变化具有较好的缓冲和隔离作用,建筑内部热湿环境对文物保存不利,主要体现在相对湿度高、波动大,湿度调控将是文物预防性保护的关键。建筑热湿环境为壁画酥碱和霉斑病害主要成因,同时促进了编竹夹泥墙体结构安全问题的发生。研究成果不仅丰富了对四川地区明代编竹夹泥墙木结构古建筑热湿环境特征的认识,而且为该建筑壁画病害和墙体结构安全问题的成因分析提供了依据。     

侨乐村:南京国民政府救助难侨措施的新尝试

论文探讨了20世纪30年代初的难侨问题及特点、侨乐村的筹办与运作模式、侨乐村推广之困境等问题;对侨乐村与华侨农场这两种难侨安置模式进行了比较分析。面对30年代初出现的大批难侨问题,以往常规的救助政策已经不能应对新情况。南京国民政府试图通过建立、推广侨乐村,从根本上实现对归国难侨的救济。侨乐村的创办具有救助难侨、开垦荒地繁荣经济的双重目的,然而在实际管理、运行中,却过度注重国家利益而忽视垦民诉求;加之其他外部环境的影响,侨乐村最终未能得到广泛推广。但通过垦荒安置难民的思路和举措被社会各界认同。侨乐村模式对抗战时期难侨、难民救助及后世华侨农场的建设都有着重要意义。     

从随葬工具的性别关联探讨中国新石器时代的性别分工

本文利用二项式分布假设检验方法对黄河流域从裴李岗到大汶口晚期和马厂期男女墓葬中随葬工具的种类和数量的变化进行了统计分析,以揭示劳动按性别分工的问题。这些墓葬的年代范围大致为公元前7000年至2000年之间,正是处于农业生产出现不久后的发展期。根据统计分析,可将随葬工具分为3类:(1)主要由男性使用的工具,(2)主要由女性使用的工具,(3)男女共同使用的工具,其中前两类可视为与性别相关的工具,并计算了每种性别关联型工具在各自遗址或墓地中所占的比例。结果表明,在这一时期中(1)社会劳动中性别分工的增强和细化(性别关联型劳动工具比例的增大和早期一些男女共用型工具晚期转化为主要系男性使用)和(2)男性在社会劳动中优势地位的完全确立(于大汶口晚期在性别关联型工具种类中,主要为男性使用的工具占绝大多数,而主要为女性使用的工具仅留下纺轮一种)。根据这一结果,简单讨论了母系氏族向父系氏族过渡的时间问题。     

China's Nuclear Energy in Light of the Disaster in Japan

An American specialist on Russian agriculture examines that country's agrarian policy, as well as the agricultural sector more generally, one year into the presidency of Dmitriy Medvedev. Focusing on the three key policy issues—state financial support, state intervention in the grain market, and international food trade policy—he assesses the extent to which current policy represents a continuation of that prevailing during the presidency of Vladimir Putin. The author discusses the appointment of a new Agriculture Minister in 2009, which may signal a different approach to the management of the sector, and concludes with an assessment of the impact of the global financial crisis.

DUCTILITY REDUCTION FACTOR OF MDOF SHEAR-BUILDING STRUCTURES

In this paper, the results of recent studies on inelastic seismic response of MDOF shear-building structures are presented. In the last few decades, the concept of response modification factor R has been introduced and developed to account for inelastic nonlinear behaviour of structures under earthquakes. In this paper, an attempt has been made to adjust and extend this concept through introducing a modifying factor R _T . This factor is used for dynamic analysis of MDOF structures, including the calculation of inelastic response spectra. Sensitivity analysis was carried out to identify the parameters that have influence on R _T . It has been demonstrated that R _T is predominantly a function of number of stories, and accordingly a relationship has been suggested. Finally, an approximate approach has been developed for evaluating the seismic strength and ductility demands of MDOF structures.     

SIMULATION OF THE FOURIER PHASE SPECTRUM FOR THE GENERATION OF SYNTHETIC ACCELEROGRAMS

This study presents the application of a new method for generating synthetic accelerograms based on statistical distributions for Fourier phase differences and Fourier amplitudes as functions of earthquake magnitude, hypocentral distance and site geology. Two important characteristics of the methodology are that it requires a small number of input parameters and that ground motion time histories can be simulated without any specific modulation function. Two areas with different tectonic patterns (North-Eastern and Central Italy) were selected for the application. The results of our analysis are reliable in the case of Central Italy because the data set is large and quite uniformly distributed, while for North-Eastern Italy our results should not be used for distances greater than 30 km.     

‘Well,Sextus, what can we do with this?’ The disposal and use of insect-infested grain in Roman Britain

Abstract

Beetle (Coleoptera) pests of stored products such as the granary weevil may have entered the archaeological record by various routes, including: (1) deliberate dumping, and usually burial, of spoilt grain with the aim of preventing further infestation of grain in storage; (2) the use of infested grain as human and animal food; (3) the incorporation of infested grain and living or dead grain pests into deposits by accident and by reworking. It is suggested that these routes, although outlined specifically for beetle grain pests, can stand as a model for the way other insects and biological remains became incorporated into the archaeological record. It also is suggested that the identification of these different depositional routes depends strongly on taking a multi-proxy (‘indicator group’ or ‘indicator package’) approach to the archaeological and biological record of urban sites.
