明清科举的正途与异途——关于福建、江西、安徽族谱资料的分析

明清时期,科举制度的推行与家族制度的发展呈现相辅相成的关系,获得功名是许多家族之凝成与延续的重要前提。获得功名的途径大体上分正途与异途两种。从族谱资料的分析可知:家族中的正途出身与异途出身往往相互支撑,共同为家族的延续和发展作出贡献。有的是前期多正途出身,后期多异途出身。有的则先由异途出身,后代逐渐走上正途。从各自的水平和行迹看,异途或许也能在一定程度上起到搜罗遗才的作用。     

要重视土地改革对乡村社会的深远影响——读《土地制度变动与中国乡村社会变革》有感

最近10年来,随着解决三农问题成为中国共产党和政府工作的重中之重,追溯和研究三农历史的论著也层出不穷,最近读了当代中国研究所王瑞芳研究员以考察新中国成立初期土地改革运动为中心写成的《土地制度变动与中国乡村社会变革》(社会科学文献出版社2010年版),感到作者运用历史唯物主义的基本原理和方法,通过透视生产关系的变革来研     

铁路交通流视角下中原城市群城市体系演变：基于城市中心性与中介性的分析

城市体系研究主要关注城市的节点性与城际关系两个方面，而城市网络研究将这两个关键要素统一起来，为进一步探讨此问题提供了新的思路。通过城际联系的视角，本文从城市的“中心性”和“中介性”两个维度来重新定义城市的节点地位。基于此，研究分析了铁路交通流视角下近十年来中原城市群城市体系整体和局部的结构变化，试图提供一种网络视角下城市体系演变的不同图景。研究发现：①城市中心性和中介性呈现出截然相反的变化趋势；②高中介性的门户城市更易提升自身地位；③城市中心性的层级结构愈发显著，而中介性更加扁平。在一体化建设的背景下，研究讨论了中原城市群城际体系演变的特征与问题。     

Computer programmes for the correction of matrix effects in the XRF analysis of glass,ceramics and related silicate systems

The quantitative analysis of glass, ceramics and related silicate systems by means of energy dispersive X-ray fluorescence spectrometry is considered and problems arising from the selective absorption of X-rays in multi-element specimens are discussed. A computer programme written in FORTRAN and based upon a “semi-fundamental parameters” approach to the correction of matrix effects in glass and chemically similar materials is fully described. Model data are provided to enable the programme to be run and tested. An “empirical coefficients” computer programme for the quantitative analysis of silicate systems is outlined and the limitations of this type of programme are pointed out. The importance of adequate sample preparation prior to X-ray spectrometric analysis is stressed.     

The impact of Russian food security policy on the performance of the food system

Abstract

Food security has guided Russia’s food policy since 2010. The article examines the impact of food security policy on the food system. The Russian model of food security combines government intervention in the form of assistance for domestic production while simultaneously restricting market access. Food security does not appear to have a deleterious impact on the food system. We measure impact on four dimensions. Financial support for agriculture continues to increase in nominal rubles. In food production, the beef and dairy branches continue to lag, but increased grain production has made Russia a global leader in grain exports. Average per capita food consumption improved, although the poor consume much less, and the decline of the ruble affects the way Russians shop. The largest impact of food security has been on food trade. Food security policy has brought food to the forefront as an instrument of foreign policy. Food trade is politicized, witnessed by the food embargo against the West and food import bans against Turkey and Ukraine.     

Health centre visits among the elderly with chronic ailments: Evidence from the Kanchanaburi Demographic Surveillance System, 2004, Thailand

This study deployed statistical and spatial (GIS) analyses to test the effects of geographic, demographic and occupational factors in predicting health centre visits among the elderly (≥60 years) with chronic ailments in Kanchanaburi Province, western Thailand. Datasets from the Kanchanaburi Demographic Surveillance System (2004 baseline survey and a 2006 project follow-up) comprised five land-use landscape and occupational strata: urban/semi-urban (industrial), rice field, plantation crop, upland and mixed economy. Travel distance to the nearest health centre was calculated following transportation routes and the GPS coordinates of individual home locations, and the number of healthcare visits under the national free universal coverage (UC) scheme reported for the previous year was used as a dependent variable in regressions. Broadly, the study found that distance was not a significant predictor of the rate of elderly health centres visits for those with co-residing spouses and/or adult children (77% of sample), and for the elderly still working (48% of the sample) who were the least likely to access healthcare. Owning motorised vehicles did not encourage visits, which also varied by land-use and occupational strata.     

Why are cultural policy decisions communicated in cool cash?

In this article, we analyze the role of the economic rationale in modern cultural policy decision communication and ask why it remains such an important factor, even though research has argued against it. Based on Luhmann’s system theory, we show how the economic rationale manifests itself in the cultural political communication as parasitic and complementary couplings, and how different communication forms are in play: the indirect, direct, and the both-and form. The point is to construct communicative positions in cultural policy. The positions involve the economic rationale in their own particular way and each of them offers themselves as a communicative platform which the culture politician can optionally step into and out of. The arts system stands out from other systems by not distinguishing itself in one single distinction and coding. In exactly this issue lies the communicative complexity which the communicating cultural politician faces and must handle. As our analysis shows, this complexity is handled by communicating within the economic rationale and coding, with the result that complexity is reduced.     

Hydrogeology of the Krafla geothermal system,northeast Iceland

The Krafla geothermal system is located in Iceland's northeastern neovolcanic zone, within the Krafla central volcanic complex. Geothermal fluids are superheated steam closest to the magma heat source, two‐phase at higher depths, and sub‐boiling at the shallowest depths. Hydrogen isotope ratios of geothermal fluids range from ?87‰, equivalent to local meteoric water, to ?94‰. These fluids are enriched in ¹⁸O relative to the global meteoric line by +0.5–3.2‰. Calculated vapor fractions of the fluids are 0.0–0.5 wt% (~0–16% by volume) in the northwestern portion of the geothermal system and increase towards the southeast, up to 5.4 wt% (~57% by volume). Hydrothermal epidote sampled from 900 to 2500 m depth has δD values from ?127 to ?108‰, and δ¹⁸O from ?13.0 to ?9.6‰. Fluids in equilibrium with epidote have isotope compositions similar to those calculated for the vapor phase of two‐phase aquifer fluids. We interpret the large range in δD_EPIDOTE and δ¹⁸O_EPIDOTE across the system and within individual wells (up to 7‰ and 3.3‰, respectively) to result from variable mixing of shallow sub‐boiling groundwater with condensates of vapor rising from a deeper two‐phase reservoir. The data suggest that meteoric waters derived from a single source in the northwest are separated into the shallow sub‐boiling reservoir, and deeper two‐phase reservoir. Interaction between these reservoirs occurs by channelized vertical flow of vapor along fractures, and input of magmatic volatiles further alters fluid chemistry in some wells. Isotopic compositions of hydrothermal epidote reflect local equilibrium with fluids formed by mixtures of shallow water, deep vapor condensates, and magmatic volatiles, whose ionic strength is subsequently derived from dissolution of basalt host rock. This study illustrates the benefits of combining phase segregation effects in two‐phase systems during analysis of wellhead fluid data with stable isotope values of hydrous alteration minerals when evaluating the complex hydrogeology of volcano‐hosted geothermal systems.
