广西人口结构与经济的协调发展分析

人口结构是影响经济发展的主要因素之一,人口结构与经济是否协调发展,是我们需要研究的问题。本文选取了1978-2010年的有关数据,运用产业结构偏差系数、就业均衡系数和城镇化率来分析广西人口结构与经济发展的协调程度。分析结果表明,改革开放以来,广西人口结构与经济发展的协调度不高,具体表现在城镇化率不高,就业结构的变动滞后于产业结构的变动,劳动就业压力大。     

人口变动对大众体育的影响

我国在一个相对较短的时期内完成了人口转变,而且这种快速的人口变动对中国社会、经济、生活的各个方面都会有不同程度的影响,对大众体育的影响自然也是题中之义.从三种不同的人口变动类型分析了生育率下降、人口流动、人口结构变动对大众体育的影响,以期为我国大众体育发展战略的制定提供一些理论参考.     

1990年珠江三角洲人口的结构性变化

从人口年龄结构、职业结构、受教育程度三方面展开分析,外来人口的大量集聚,延缓了珠江三角洲人口老龄化进程。教育的发展,使低龄适龄劳动人口在业率大幅度下降,人均受教育水平有较大幅度提高,中高等学校在校生的集聚度略在下降,职业结构的变化表明珠江三角洲仍以工业化为经济和城市发展的主要动力,但主要城市已进入以二三产业并重促进城市发展的阶段。今后应充分发挥大中城市作为文化教育中心的,以各类城市间的合作,促进人力资源开发,促进多层次城市经济的蓬勃发展,为不同人力资本存量的劳动者提供多样化的就业机会,提高人力资源的产出效益。     

人口变动对山西省体育教学资源的影响

在充分研究学校体育的前提下,采用文献资料法、访谈调查法、问卷调查法、数理统计法和逻辑分析法,以山西省人口普查资料为基础,计算出山西省中学适龄人口的规模,并对2010年以前的山西省中学适龄人口做出预测,对影响山西省中学体育的场地、器材设施方面进行了分析.     

高等教育是适度发展,还是大力发展

本文建议调整高等教育政策，即由适度发展转变为大力发展。因为我国将在今后约15年左右的时间，由低收入国家转变为下中等收入国家。从世界其它国家和地区高等教育发展的指标来看，下中等收入国家受过高等教育者在人口中所占的比例较低收入国家有极为显著的提高，高等教育适龄人口入学率或每10万人口中的大学在校生数大幅度上升。本文建议：用15年左右的时间，即到2010年或稍后，将我国受过高等教育者在人口中所占的比例由目前的2％提高到8～9％，与此相应，建议分3步走，力争在2010年或稍后，使我国高等教育适龄人口入学率达到乃至超过下中等收入国家20世纪90年代初亦即约27％（联合国教科文组织口径）的平均水平。     

“高等教育发展阶段论”不适合中国国情

20世纪60年代,美国著名高等教育理论家马丁·特罗提出“高等教育发展阶段理论”。他认为,随着社会的发展和教育机会的扩大,高等教育必然从精英型(大学生占适龄人口比例在15％以下)发展到大众型(大学生占适龄人口15％至50％),再过渡到普及型(大学生占适龄人口50％以上),并确信世界各国的高等教育发展都应遵循这一理论。目前人     

上海人力资源中若干不容忽视的问题

人力资源是经济活动的主体,事关经济的持续发展。人力资源再生产周期较长,因此必须未雨绸缪,超前发现问题与提出对策。本文分析上海人力资源中的几个突出问题,并探索一些具体解决思路。 问题一:总体来看,上海劳动力结构有老化趋势、文化素质相对偏低。 1990年上海市劳动适龄人口的平均年龄为35.3岁,2000年估计达38.8岁。另据 1995年人口抽样调查显示,上海市劳动年龄人口中 16-24岁组人口     

区域人口空间分布多尺度动态分析方法研究

贯彻落实国家中部崛起计划、 制定区域人口政策以及促进湖北省人口经济与资源环境相均衡等提供科 学决策依据。 在城市-城市群-省域多级尺度特征上, 结合地统计方法、 空间自相关分析、 分段回归模型等, 提出了一种区域人口空间分布格局多尺度动态模拟流程方法。 利用此方法, 在武汉市-武汉城市圈-湖北省 3 个 尺度上, 对湖北省 1990 ~2010 年人口空间分布结构进行了动态模拟实验分析。 结果表明, 20 年来, 武汉市人 口持续向中心集聚, 依旧处于城镇化早期阶段, 且其人口格局被分割为两个不同的结构带; 在 3 个地理尺度 上, 人口空间分布均有表现为明显的集聚特征, 随地理尺度的扩大, 人口密度梯度趋于平滑。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。     

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.
