明代顺天府地区巡检司的设置、演变与分布研究

巡检司是明代维护基层治安的重要机构,顺天府地区作为明代的首善之区和边关重地,前后共设置了22个巡检司。通过对这些巡检司的设立时间、裁革时间、衙署驻地及治所迁移情况进行详细考证,发现这些巡检司大多分布在长城沿线重要的关口或运河沿线主要的节点附近,其中最重要的地方有两处,分居京师东西两翼,分别在京师西部山区和京东运河沿线。这两条线关系着京师西部的治安和东部的漕运,因此一直受到重视,巡检司分布得较为均衡,且长期稳定。从数量上看,明初洪武年间巡检司较少,永乐年间设置的巡检司最多,并奠定了此后顺天府地区巡检司分布的基本格局。弘治末年至正德初年,巡检司数量达到最高峰。此后由于国家财政的困难,巡检司在嘉靖年间被大量裁革,它们对基层的控制也日渐式微。     

Roman traces in Germania magna: New thermoluminescence and pIRIR290 data from a lime kiln at Bergisch Gladbach,Germany

The applicability of a post‐infrared infrared stimulated luminescence (pIRIR₂₉₀) protocol and two different thermoluminescence (TL) protocols—a single aliquot regeneration (SAR) and a multiple aliquot additive dose (MAAD)—was tested on six polymineral fine‐grain (4–11 μm) samples extracted from the wall remains of a Roman lime kiln and a Roman roof tile. These remains had been excavated close to Bergisch Gladbach, which was at that time part of Germania magna. For the pIRIR₂₉₀ measurements, no dependence of D_e on first‐stimulation temperature was detectable, and the standard first stimulation temperature at 50°C was adopted. Fading tests and dose‐recovery tests were made for all samples. Background subtracted glow curves were recorded up to 480°C for TL after a preheat of 220°C for 120 s. A‐values were determined for all TL and pIRIR measurements. The results for all three protocols were fairly consistent, and TL and pIRIR₂₉₀ protocols are shown to be suitable to estimate reliable equivalent doses for the fired kiln walls. The resulting ages are in agreement with the expected time range—Roman Iron Age—and with independent age control provided by radiocarbon ages of animal bones and charcoal from the firing chamber.     

The Spatial Organization of Bone Crafting During the Middle and Late Mesolithic at Ringsjöholm and Strandvägen in Sweden

This paper focuses on the spatial distribution of bone tool production waste from two Mesolithic sites in Sweden, Ringsjöholm and Strandvägen, with well-preserved faunal remains including bone and antler artifacts. Local production on both sites has generated a variety of identifiable waste products deriving from complete chains of production, including unmodified bones, debitage and finished products. Identified categories include: blanks, removed epiphyses, bone flakes, and preforms. Identification of species shows that antler and bone from red deer were the preferred raw materials. Spatial statistical analyses confirm that different stages of bone tool production were organized within separate areas of the sites and that larger items were discarded in the water along the shorelines. Interestingly, blanks and preforms seem to have been stored under water for future use and demarcated clusters of bone flakes in association with dwellings represent “bone knapping floors” where production was more intense than in other areas.     

The settlement mounds in Divtasvuona/Tysfjord,North Norway. Traces of a Sami fisher-farmer economy

In Tysfjord Municipality, North Norway, written sources mention Sami farms in the sixteenth and seventeenth centuries. The farms had a mixed economy, with an emphasis on agriculture, fishing, hunting and gathering. On some of these farms there are documented settlement mounds. Minor excavations have been carried out on several of these archaeological sites. A pollen sample has also been taken from one of these locations. By using radiocarbon dating and artefact analyses it is possible to date the settlement mounds back to the Early Middle Ages. The establishment of these cultural monuments documents a change in the economy, with animal husbandry becoming more important. During the Middle Ages, cultivation of barley arose as a new element of the economy. The article addresses the question of whether this change in the economy can be linked to a Sami or a Norwegian population.     

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.     

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。     

Starch grains analysis of stone knives from Changning site,Qinghai Province,Northwest China

Plant residues recovered from prehistoric stone artifacts can be used to help explain tool function and plant use. At the Changning site in Qinghai Province, Northwest China, dating from 4000 yr BP, we examined starch granules extracted from three slate stone knives. A total of 153 starch grains were retrieved from three stone knives, from which we identified starches from legumes, the Triticeae tribe, foxtail millet (Setaria italica), broomcorn millet (Panicum miliaceum), roots and tubers. These results indicate that the stone knives may have been used for a variety of activities that included reaping grasses and food processing. The species of starch grains retrieved from the study sample reveal that diverse crops were cultivated at the Changning site 4000 years ago.     

‘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.     

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.
