从远景规划到概念规划

城市发展战略的研究和规划、从国外到国内,从上世纪末的远景规划到本世纪初的“概念规划”,一脉相承,并随着经济社会的发展和变革不断发展,概念规划是在竞争年代下一个战略研究的创新。城市规划应包括四个层面:城市研究、城市规划、城市设计、城市管理,而城市发展的战略研究,正是加强了城市研究,这种高层次的研究工作,对城市发展发挥了纲举目张的作用,它并不企图取代城市总体规划,而是更丰富了城市规划内容和完善城市规划的体系,对城市规划工作者也是一种知识更新的挑战。     

Post-concussive symptoms in children with mild traumatic brain injury.

To investigate postconcussive symptoms (PCS) following pediatric mild traumatic brain injury (mTBI), 8- to 15-year-old children with mTBI (n = 186) and a comparison group with uncomplicated orthopedic injuries (OI, n = 99) were recruited from two emergency departments. Parent and child ratings of PCS and symptom counts were obtained within 3 weeks after injury (baseline) and at 1, 3, and 12 months postinjury. The mTBI group also completed magnetic resonance imaging at baseline. Group differences were examined using growth modeling, controlling for age at injury, sex, socioeconomic status, and (for parent-based measures) preinjury symptom levels. Relative to the OI group, the mTBI group had higher ratings of somatic PCS and parent counts of PCS at the initial assessments, but higher parent ratings of cognitive PCS and child counts of PCS throughout follow-up. Higher levels of PCS in the mTBI group were associated with motor-vehicle-related trauma, loss of consciousness, neuroimaging abnormalities, and hospitalization. The findings validate both transient and persistent PCS in children with mTBI and document associations of symptoms with injury and noninjury factors.

关于师范生免费教育政策的思考

师范生免费教育政策对于解决贫困师范生的就学问题、保障基础教育师资质量、促进教育发展和教育公平具有重大的现实意义。该政策在具体实施过程中,可能出现新的问题：对非部属师范院校会产生新的不公平;真正热爱教育事业的师范生不一定能享受政策优惠;落实免费师范毕业生的职后保障成本太高;免费师范生的学习动力、培养质量难以保证等。对此．有必要采取相应的对策：提高我国教师的待遇;增强师范生的学习动机;注重免费师范生的培养质量;积极探索师范教育免费制度的多种模式。

内蒙古巴林左旗碧流台村北铅锌矿地质特征及远景预测

巴林左旗是内蒙古赤峰市重要的铅锌多金属矿产的产区,通过对碧流台村北铅锌矿区域地质背景、成矿地质特征、物化探异常特征、矿体特征等因素的综合分析,总结了碧流台村北铅锌矿成矿地质条件、找矿标志及矿床成因,同时对矿区进行了远景预测,认为矿区深部具有寻找中型铅锌盲矿体的潜力,对矿区下一步找矿工作具有重要的指导意义。     

Special issue editorial: Prospective memory in 2010.

In order to raise awareness of prospective memory, this special issue features contemporary research on the topic. The occasion for a special issue was the 3rd International Conference on Prospective Memory, which was held in July 2010 in Vancouver, and which brought together nearly 100 scientists from 16 different countries. The conference showcased new research, as well as a host of breakthrough discoveries and methodological insights, and it served to underscore why prospective memory deserves and is likely to receive more prominence in the future. As has been and continues to be the case for retrospective memory, however, most prospective memory research seems to be focused on its episodic component, on questions such as the following: Once a plan has been made, and my attention has turned elsewhere, how does that plan come back to mind at the appropriate time or context? Why do plans sometimes to pop into mind all of the time, including when our attention ought to be focused elsewhere? Why does an obvious cue, such as the mailbox in my way, sometimes fail to reactivate a previous intention? What strategies, if any, are available for improving prospective memory? The articles in this issue address these and related questions. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

辽东清原金富集带含金韧性剪切带远景评价

王小堡-东庙岭-金鸡背这一辽东清原金富集带,已往以寻找石英脉型金矿为主。近两年来,笔者通过在该区进行的实地工作及与东北大学专家教授联合攻关,确认了此金富集带为一典型的含金韧性剪切带,同时总结归纳出各种金成矿类型及其特征,其中蚀变岩型金矿尤为重要,并将其与吉林六批叶大型韧性剪切带中的蚀变岩型金矿加以类比,在此基础上对该区域找矿远景提出评述。

Clinical relevance of heavy drinking during the college years: Cross-sectional and prospective perspectives.

This study investigated the clinical relevance of heavy drinking during the college years and beyond on concurrent and prospective alcohol-related problems in a high-risk sample (N?=?377). Measures of heavy drinking and alcohol-related problems were significantly correlated cross-sectionally over the study frame, regardless of how these constructs were operationalized. However, the magnitude of the association between heavy drinking and alcohol-related problems declined substantially over time, with the most pronounced decrease following the college years. Despite this cross-sectional decrease in the association between heavy drinking and alcohol-related problems over time, heavy drinking during the college years significantly and substantially predicted alcohol-use disorders up to 10 years later. Implications for assessment of heavy drinking as well as prevention of problematic alcohol use in college students are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

中国主要含油气盆地地球化学场特征

依据酸解烃甲烷、重烃和ΔC的均值、变异系数,中国主要含油气盆地的地球化学场划分为高、中、低背景场以及高度非均匀场、非均匀场及均匀场。中国主要含油气盆地地球化学场总体趋势是西部(鄂尔多斯、四川盆地以西)含油气盆地高于东部含油气盆地,东北含油气盆地低于中部含油气盆地,而高于南方含油气盆地。其主要原因除与油气地质条件相关外,还取决于近地表沉积物的性质,以及地理、地貌的景观条件。在全国化探概查成果的基础上,结合已知油气藏化探异常的综合特征,在油气勘探程度相对较低的地区,选择局部综合异常强度大、多种指标相互配置好的松辽盆地中央凹陷南部的长岒断陷、西部斜坡及西南隆起钱家店断陷;周口盆地谭庄-沈丘凹陷;松潘-阿坝地区的辖曼-曼日玛-阿万仓异常区及下扬子地区的无为-和县及望江异常区为油气勘探的远景地区。并在7个盆地(或地区)化探普查成果的基础上,进一步划分了25个有利的含油气区带。
