Die ‚Deutsche Physik’︁ in der Selbstkritik des NS‐Ideologen Alfred Bäumler

In 1944, the Nazi ideologist Alfred Baeumler wrote a memorandum for his boss Alfred Rosenberg, Adolf Hitler's commissioner for the political education of party members. In this sensational memo, which did not become known until long after 1945, Baeumler spoke out against the promotion of under‐performing physicists who oust highly‐qualified non‐Nazi scientists at the universities without submitting adequate research results. – Rosenberg's response is not known. What is known, however, is that Baeumler did not manage to change the situation criticised by him.     

River meander behaviour and instability: a framework for analysis

Recent empirical and theoretical work on river meanders suggests that instability is inherent. Within this context, an occurrence of multiple cut-offs could be interpreted as a clustering associated with self-organized criticality. Types of meander behaviour ranging from stable to chaotic are examined as trajectories or attractors within the phase space of rate of meander movement and bend curvature and change to the system is explored as shift from one attractor to another. It is suggested that this new approach provides insights into meander dynamics and provides a basis to identify the conditions, limits and constraints under which different behaviour occurs. Basic controls of energy and resistance underlie planform behaviour, but need to be refined in relation to the morphology and stability of channel courses.     

湖北丹江口市玉皇庙遗址调查简报

玉皇庙遗址位于湖北省丹江口市境内,现为丹江口水库中一小岛。1995年,文物工作者对南水北调工程文物调查时发现该遗址。在遗址采集新石器时代和周代遗物。新石器时代遗物与青龙泉和大寺遗址、朱家台遗址和乱石滩遗址等出土的同期遗物相近。周代遗物与官山河两岸早年发现的同期遗物相似。

Assessing the reliability of pRIA for identifying ancient proteins from archaeological contexts

The use of immunological techniques for identifying the origin of proteins and inferring foodstuffs exploited by prehistoric occupations has been conducted for several decades. Cases of experimental laboratory and archaeological studies have shown the potential of these techniques for reliable results. However, very few of these case studies employ archaeological sites that have excellent preservation and high-resolution spatial contexts between identifiable faunal remains, features, and stone tools. We present an assessment of the identification reliability of one immunological technique, protein radioimmunoassay (pRIA), using faunal remains and stone tools from two sites from arctic and subarctic contexts. The results of this research indicate that, even in contexts with excellent preservation, the identifications produced by the pRIA technique are subject to misidentification and cross-reactions due to diagenetic alteration of proteins. We propose a higher minimum reaction value (percent binding of labeled antibody) that mitigates these effects, and renders the pRIA results more reliable for ancient, poorly preserved organic remains.     

张衡地动仪的发明、失传与历史继承

地动仪的发明和失传存在深厚的社会背景.悬挂物对地震的良好反应是诞生科学思想的物质基础.地动仪是对天然验震器的发展,张衡不仅在利用物体惯性测震上,也在检测和记录地震微弱信号上有技术创新,成功测到公元134年12月13日陇西地震.天诫观念把自然现象与社会问题混为一谈,导致张衡晚年和地动仪的悲剧.仪器可能失传于东汉末年,当时发生了洛阳大火、毁铜铸钱、京师搬迁、人口剧减和灵台被毁等极端严重的社会混乱.张衡的科学思想和实践对现代地震学的起步发挥过思想启迪作用.对地动仪的研究需要开展科学实验,学术观点的统一只能建立在科学实验的基础上.     

20世纪50年代安徽水灾中医疗救助活动述论——以1954年淮河水灾为例

长江经济带交通基础设施空间均衡度研究

利用1997-2013年长江经济带各省份数据,研究了交通基础设施空间均衡和极化程度及其影响因素,并构建动态面板数据模型,采用系统GMM估计进行了实证检验。研究结果表明:长江经济带交通基础设施发展较快,但存在空间非均衡和空间极化特征;铁路密度和公路密度的空间非均衡程度依次递减,区域间差距是空间非均衡的主要原因;公路密度空间极化程度不断增加,且高于铁路密度的极化程度;财政支出、国际贸易、人力资源和新经济地理四大因素对交通基础设施空间均衡和极化具有影响,但影响效果不同。本文拓展了交通基础设施的研究,为长江经济带交通基础设施协调发展及互联互通战略顺利实施提供了政策依据。     

黄河流域区域经济差异的时空动态分析

以黄河流域的各地级市为研究单元,人均GDP为测度指标,综合运用不同时空动态分析方法,在Open Geoda和Pysal2.7软件支持下,对1990-2013年黄河流域73个地级市经济发展水平空间格局和演变过程进行分析。研究表明:黄河流域整体区域经济差异呈现先扩大后减小的趋势,东部地区内部差异最显著对整体差异贡献最大,中部、西部区域经济差异相对稳定;流域经济空间异质性明显,存在显著的空间正相关,区域经济格局两极化明显且东部经济水平明显高于中西部地区,流域经济发展的热点区主要分布在山东省内,冷点区主要分布在甘肃、陕西、青海等部分州市;通过分析黄河流域73个地级市经济发展类型时空演变特征,反映出黄河流域经济发展存在俱乐部趋同趋势,初始状态对区域经济发展具有重要作用,区域背景亦具有一定作用,区域经济水平的跨越式发展基本不存在。
