浅谈加强建筑施工企业党风廉政建设的路径和方法

建筑施工企业与其它生产企业有着不同的行业特点．施工点多、面宽、战线长,多属外地施工,过着“游击战士”的生活;管理跨度大,项目类型杂．接触人员广：多以单个项目管理为主．派出的干部和管理人员独立处置事物的机率多。由于这些行业特点的不同．给党风廉政建设也带来了很多的特殊性．某种角度讲．也给建筑施工企业抓党风廉政建设带来了与行业相适应的特点．二冶作为一个以冶金建设与民用建筑施工为主的老企业．在多年抓党风廉政建设的实践中．摸索出了与其行业相适应的党风廉政建设的方法和途径。

水泥制造企业CO2排放量核算方法的实证研究

介绍了水泥制造企业二氧化碳排放量核算的基本原则与方法，并结合某水泥制造企业2012年的实际活动水平数据进行了实证研究．研究结果表明，我国《水泥生产企业二氧化碳排放量计算方法》根据物料平衡原理，较好地考虑了水泥制造企业二氧化碳排放量测算的可操作性和不确定性，比较适合我国现阶段水泥制造企业的碳排放量核算．鉴于我国区域性的碳排放交易市场已经正式建立和启动，我国应尽快出台针对不同行业企业二氧化碳排放量计算方法的国家标准，以利于碳排放交易这项环境政策工具在我国顺利实施．

城市公共交通票价模式研究

目前国内公共交通行业普遍存在着服务不到位．顾客抱怨多等现象，并由此造成了公突出行分担率不断下降．公交企业连年亏损的不利局面。本文重点分析比较了三种定价模型，给出了不同城市公共交通票价的定价。     

股权结构与企业绩效

资本结构与企业绩效的关系也不是固定不变的。认为企业业绩随资本结构优化而增加随后又回落的传统结论在我国上市公司中没有得到验证,由此可见单纯研究资本结构与企业绩效的关系是远远不够的。将各行业面临的不同环境变数纳入实证研究范畴相当必要,因为行业特性决定了不同的经济环境和制度环境对各行业的影响不同,导致各行业的融资偏好存在差异,从而影响企业绩效;不同时间段环境波动的不一致,对各行业的影响也是不一样的。

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.     

Perspherical Approaches for Electrons in Atoms and Charged Excitons in Quantum Wells

Instead of following Fock’s expansion,we solve the Schrodinger equation for some quantum mechanical manybody systems such as electrons in atoms and charged excitons in quantum wells in a similar way in hyperspherical coordinates by expanding the wave functions into orthonormal complete basis sets of the hyperspherical hannonics(HHs)of hyperangles and generalized Laguerre polynomials(GLPs)of the hyperradius.This leads the equation to     

Advances in broadband wireless communications under high-mobility scenarios

Future mobile communication systems aim at providing very high data transmission rates, even in high-mobility scenarios such as high-speed wheel-track trains, maglev trains, highway vehicles, airplanes, guided missiles or spacecraft. A particularly important commercial application is the strong and increasing worldwide demand for high- speed broadband wireless communications （up to 574.8 km/ h test speeds or 380 km/h commercial speeds） in railways, providing data, voice and video services for applications such as onboard entertainment services to passengers, train control, train dispatch, train sensor status handling and sur- veillance. In such high-mobility scenarios, there are a number of communication challenges, including fast hand- over, location updating, high-speed channel modeling, estimation and equalization, anti-Doppler spreading tech- niques, fast power control, and dedicated network architec- ture. Because signal transmission in very high-speed scenarios will inevitably experience serious deterioration, it is imperative to develop key broadband mobile communi- cation techniques for such high-speed vehicles.

Scale-based spatial data model for GIS

Being the primary media of geographical information and the elementary objects manipulated, almost all of maps adopt the layer-based model to represent geographic information in the existent GIS. However, it is difficult to extend the map represented in layer-based model. Furthermore, in Web-Based GIS, It is slow to transmit the spatial data for map viewing. In this paper, for solving the questions above, we have proposed a new method for representing the spatial data. That is scale-based model. In this model we represent maps in three levels: scale-view, block, and spatial object, and organize the maps in a set of map layers, named Scale-View, which associates some given scales.Lastly, a prototype Web-Based GIS using the proposed spatial data representation is described briefly.

Man Is Unable to Change the Miserable Life——Analysis of the Arrangement of Four Characters in The Glass Menagerie

Tennessee Williams is considered as one of the most important American playwrights since World War II.The Glass Menagerie is his first successful drama,which describes a tragic situation of family and means to say that Man is unable to change the miserable life,no matter whatever means he try,This essay focuses on the analysis of the arrangement of the four main characters:Laura.Amanda,Jim and Tom to reveal the theme.Laura is fragile.Amanda is brave.Jim is vital.Tom is sensible.And all of them develop and try the different means to struggle against life,but fail tragically.With the evidence,the paper comes to conclusion naturally that Man is unable to change the miserable life,and he dooms to fail.     

Characterization of root-nodulating bacteria on Retama raetam in arid Tunisian soils

The aim of this study is to investigate the diversity of Retama raetam root-nodule bacteria isolated from arid regions of Tunisia. Twelve isolates, chosen as representative for different 16S rRNA gene patterns, were characterized by 16S rRNA gene sequencing and phenotypic analysis. Isolates were assigned to Sinorhizobium, Rhizobium and Agrobacterium. Symbiotic properties of Sinorhizobium and Rhizobium isolates showed a large diversity in their capacity to infect their host plant and fix atmospheric nitrogen. Strain RK 22 identified as Rhizobium was the most effective isolate.
