Research relevance, 'knowledge transfer' and the geographies of CASE studentship collaboration

The Co-operative Awards in Science and Engineering (CASE) studentship programme of the UK Research Councils provide one example of wider efforts internationally to encourage so-called 'knowledge transfer' and thereby harness publicly supported university research more closely to the goals of national competitiveness, regional economic development and local regeneration. In this paper we describe the implications of how the various UK research councils have interpreted the objectives and beneficiaries of 'knowledge transfer', both for the relative opportunities available to human and physical geographers for collaboration through CASE and for the sorts of values that their research must serve. Then, we draw on unpublished data from the Economic and Social Research Council (ESRC) to explore the geographies of CASE studentship allocation and participation. The broad regional and institutional patterns of participation we describe have important implications for ongoing debates in the UK about research selectivity and the role of the university as an engine of local development, while the striking disciplinary patterns of CASE participation, and in particular the overwhelming success of geographers in this competitive programme, provide an opportunity to reassess claims about whether and for whom geographical research is relevant.     

Karst database development in Minnesota: design and data assembly

The Karst Feature Database (KFD) of Minnesota is a relational GIS-based Database Management System (DBMS). Previous karst feature datasets used inconsistent attributes to describe karst features in different areas of Minnesota. Existing metadata were modified and standardized to represent a comprehensive metadata for all the karst features in Minnesota. Microsoft Access 2000 and ArcView 3.2 were used to develop this working database. Existing county and sub-county karst feature datasets have been assembled into the KFD, which is capable of visualizing and analyzing the entire data set. By November 17 2002, 11,682 karst features were stored in the KFD of Minnesota. Data tables are stored in a Microsoft Access 2000 DBMS and linked to corresponding ArcView applications. The current KFD of Minnesota has been moved from a Windows NT server to a Windows 2000 Citrix server accessible to researchers and planners through networked interfaces.

微陆块属性厘定的依据——以中亚造山带南缘中段为例

造山带中残存有许多前寒武纪地质体,其中一些被当作前寒武纪基底用于探讨所在微陆块的大地构造属性。由于微陆块属性对于造山带结构和演化具有重要意义,以及所讨论的前寒武纪地质体蕴含地球早期历史演化信息,对微陆块属性的厘定成为造山带研究的重点和难点问题之一。笔者等以中亚造山带南缘中段的微陆块为例,总结梳理了微陆块厘定的相关依据：岩石组合和变质变形特征,碎屑锆石谱峰显示的源区时代特征,地质事件序列,前寒武纪地壳演化信息,继承锆石、捕获锆石和古生代侵入体同位素显示的深源地壳信息,以及地球物理等方面的特征。由于不同学者采用的厘定依据不同,对微陆块属性认识争论不断,即使相同依据也有一定的差异,从而影响对造山带结构和演化的认识。基于以上原因,笔者等认为前寒武纪基底的亲缘性探讨不仅要注重岩石组合和形成时代,还要在精细野外解剖和高精度年代学工作基础上,注意其变质—变形特征、接触关系、源区时代特征、岩石成因和构造环境、地壳增生信息和深源地壳信息等的综合对比分析,以得到较全面依据,探讨其构造属性。当获得一组前寒武纪地质体信息时,可先进行同构造单元内对比,再与其他构造单元对比。当特征相异时则需进行构造单元拆分或考虑构造就位的可能（包括但不限于推覆体、走滑外来体、俯冲刮削的构造岩片）;当特征相似时,可能指示了相同微陆块的裂解或破坏或者不同的微陆块共同经历了相似的前寒武纪演化历程。     

青海省地质特征及典型地质标本采集经验

地质标本是地史演化和地学研究的见证物,同时也是地质宣传和教学的基础资源和核心材料。以习近平新时代生态文明建设思想为指导,对青海省地质特征及典型地质标本采集经验进行深入分析和讨论。研究结果表明青海省处于不同时期规模巨大的造山系中,区域地质活动强烈,经过亿万年的地质演化,形成了丰富的具有典型性和代表性的地质标本。典型地质标本采集时可重点考虑北祁连蛇绿岩、中南祁连构造糜棱岩、柴北缘花岗伟晶岩、西秦岭矽卡岩、青南流纹岩和不同地质年代形成的化石等地质体。同时此次在采集地质标本时得出的宝贵经验,对于今后深入剖析省内地层时空接触关系和构造活动特征、揭示地层演化历史和矿藏分布规律、以及为吸引更多的国内外地学爱好者提供了具有高原特色的新场景和新生态。     

Cloning and characterization of glyceraldehyde-3-phosphate dehydrogenase encoding gene inGracilaria/Gracilariopsis lemaneiformis

Glyceraldehyde-3-phosphate dehydrogenase （GAPDH） plays important roles in various cellular processes. A cytosolic GAPDH encoding gene （gpd） of Gracilaria/Gracilariopsis lemaneiformis was cloned and characterized. Deduced amino acid sequence of the enzyme of G. lemaneiformis had high homology with those of seven red algae. The 5＇-untranslated regions of the GAPDHs encoding genes of these red algae varied greatly. GAPDHs of these red algae shared the highly conserved glyceraldehyde 3-phosphate dehydrogenase active site ASCTTNCL. However, such active site of Cyanidium caldarium was different from those of the other six algae at the last two residues （CL to LF）, thus the spatial structure of its GAPDH active center may be different from those of the other six. Phylogenetic analysis indicated that GAPDH of G. lemaneiformis might have undergone an evolution similar to those of Porphyra yezoensis, Chondrus crispus, and Gracilaria verrucosa. C. caldarium had a closer evolutionary relationship with Cyanidioschyzon merolae than with Cyanidium sp. Virtual Northern blot analysis revealed that gpd of G. lemaneiformis expressed constitutively, which suggested that it might be house-keeping and could be adapted as an inner control in gene expression analysis of G. lemaneiformis.     

新亚欧大陆桥(河南段)经济带地下水资源形势的研究

新亚欧大陆桥,是又一条连接亚欧大陆的“黄金通道”。陆桥的开通,给河南城市群的崛起和城乡产业经济的发展带来了契机。作为经济可持续发展限制因素之一的地下水资源,在陆桥（河南段）经济带范围内,能否满足沿线经济对地下水的需求？研究结论是：地下水形势不容乐观,潜力尚有８７×１０８ｍ３／ａ,同时还存在超采量３８８×１０８ｍ３／ａ,城乡开发地下水强度不一,已引发多种环境地质问题,对陆桥（河南段）经济带的发展构成了严重威胁。为缓和陆桥（河南段）沿线用水矛盾,必须遵循“因地制宜,量水为出,适度开发,统一规划”的原则,在开源、节流、管理上做好用水文章,充分发挥地下水资源的整体效益,实现陆桥（河南段）经济带地下水的可持续开发利用。
