Research on the Construction of Highly Educated Counselors in Higher Vocational Colleges ——A Case Study of Higher Vocational Colleges in X City
随着党和国家对高校辅导员队伍建设工作的重视,近年来,各大高校纷纷兴起配备高学历辅导员的热潮,高职院校辅导员队伍也基本实现高学历化,辅导员是开展大学生思想政治教育的骨干力量,对和谐校园构建发挥着重要的作用。然而研究表明,高职院校高学历辅导员队伍的实际工作状况并不令人满意,与高校对辅导员工作的要求还有很大差距,达不到预期目标。 本研究通过梳理并借鉴已有的研究成果,运用了文献法、问卷调查法、访谈法等研究方法,对X市高职院校高学历辅导员队伍建设情况作了深入的调查研究,掌握一手研究资料。问卷调查发现高职院校高学历辅导员队伍建设主要存在以下几个问题:一、高学历辅导员队伍年轻化程度高,队伍稳定性差。辅导员...As the Party and the country have attached great importance to the construction of highly educated counselors in recent years, a vigorous upsurge of equipping highly educated counselors has rose in many universities and highly educated counselor team in higher vocational colleges has realized high-credentialization on the whole. Counselors are the backbone to carry out ideological and political e...学位:教育学硕士院系专业:教育研究院_高等教育学学号:X200828001
Study On Accounting For Tradable Emission Rights
可交易排放许可权交易制度作为一种新的治理企业污染的市场手段,将市场机制充分地运用于环境资源的配置,在总量控制的前提下,通过可交易排放许可权的交易,实现低成本治理污染,有利于环境保护和经济的可持续发展。在借鉴国外成功经验的基础上,我国进行了可交易排放许可权交易的尝试。随着可交易排放许可权交易在我国的逐渐展开,企业将会面临如何恰当地对可交易排放许可权进行会计处理的问题。鉴于此,本文重点围绕可交易排放许可权会计问题,进行了详细地分析。本文共六章。第一章,介绍了研究背景,对文献进行回顾,并提出本文的结构与不足。第二章,从可交易排放许可权的产生入手,对可交易排放许可权的定义、经济学理论依据及可交易排放许...Compared with the measures based on administrative command, emission rights trading institution, as a new market oriented measure to deal with firms’ pollution, has greater advantages. It fully exerts the market mechanism on the collocation of environmental resource, realizes low cost pollution management through the emission rights trading on the premise of total amount control, and helps to prot...学位:管理学硕士院系专业:管理学院会计系_会计学学号:20031106
Ideology and Popular literature
对通俗文学的研究,始于对其社会影响力的重视而非艺术特征的理论考察。作为一个不可忽视的社会文化现象,通俗文学十分鲜明、生动地反映了社会转型、社会心理变迁、生活方式的改变等方面,但它并非对其进行直接、机械的反映,而是和纯文学一样是通过对“意识形态”材料的加工改造而来的。与意识形态的关系一直是通俗文学研究中的重要课题。在发展中形成了对意识形态的支持和强化、对意识形态的回避及委婉的反抗两种对立的观点。前者多以精英知识分子的姿态俯视通俗文学;后者则夸大了受众的能动作用,忽视了大众文化中意识形态的控制力量。两种观点都是在论述大众文化时形成的,都忽视了通俗文学自身的文学特性;都没有将对通俗文学与意识形态关系...The study of popular literature begins as its emphasis on social impacts but not as a theoretical requirement. As an indispensable social phenomenon, the popular literature reveals a lively and vivid picture in social aspects as social transition, mental transformation and life-style changing. Popular literature is not direct and mechanic reveal the Ideology, but one that is, like pure literature,...学位:文学硕士院系专业:人文学院中文系_文艺学学号:20030100
论以纳税人为主体的税收文化
税收是个具有悠久历史的概念,税收文化则是将税收纳入到了一个新的范畴——文化中加以考虑,这有利于其更好地发展。纳税人是税收的主体要素,也是税款的直接来源。本文从税收文化的概念浅析、中西文化不同所导致的税收文化的差异,探讨了我国目前税制体系中存在的主要问题。认为应从纳税人的立场出发,分析税收文化的建设,建立符合纳税人利益的现代税收文化
Application of Options Theory in the New High-tech Venture Valuation
高新技术创业企业评估的主要资产是专利权 ,专利权是一种灵活的选择权 ,它给企业以一种类似期权的权力 ,即可以选择有利的市场时机投入资金开发该专利 ,当企业进行了不可逆投资后 ,企业就相当于执行了期权。鉴于专利权与期权都是一种不附带义务的选择权 ,期权定价理论就为高新技术创业企业的价值评估提供了理论基础。本文对期权理论在高新技术创业企业评估中的应用进行了探讨。The major asset to be assessed in new high-tech ventures is patent right. As a flexible option, patent right gives the venture a kind of options right, i.e. the venture can choose to develop the patent product at favorable market situations. The venture executes options once it has made investment. Options pricing theory has offered theoretical basis for the valuation of new high-tech ventures since both patent right and options are options without any complementary obligations. This paper studies the application of options theory in the new high-tech venture valuation

聚羧酸系减水剂对早期混凝土收缩变形的影响
将同一品牌、三种类型的聚羧酸系减水剂掺入混凝土中,研究它们对早龄期混凝土收缩变形的影响及其规律。结果表明:三种类型的聚羧酸系减水剂对早龄期混凝土的收缩变形均能产生较大的影响,影响程度随着减水剂类型的不同而变化。在固定配合比条件下,外掺缓凝型聚羧酸系减水剂不仅不会使早龄期混凝土产生收缩变形,反而出现微膨胀,具有独特的减缩功效;但是,外掺标准型、早强型聚羧酸系减水剂则增大了早龄期混凝土的收缩变形,且外掺早强型聚羧酸系减水剂的增缩作用更加显著。因此,优先选用缓凝型聚羧酸系减水剂是减少早龄期混凝土收缩变形的有效手段
Direct determination of nitrites,nitrates and phosphates in seawater using suppressed conductivity ion chromatography with large volume injection and on-line sample preparation techniques
采用戴安公司谱睿(PrE)在线样品除氯技术,结合OnguArd bA柱去除硫酸盐,建立了离子色谱直接测定海水中亚硝酸盐、硝酸盐和磷酸盐的方法。该方法以IOnPAC Ag23为富集柱,高容量IOnPAC AS23为分离柱,淋洗液自动发生装置在线产生kOH溶液进行梯度淋洗,抑制电导检测。实验结果表明:样品稀释5~10倍时,直接进样不会干扰目标物测定。当流速为1 Ml/MIn、进样量为500μl时,海水中nO2--n、nO3--n、PO34--P的方法检出限分别为0.3、0.4、0.2μg/l,线性范围分别为10~500μg/l、14~680μg/l、3.4~170μg/l,线性相关系数r均大于0.999 0。测得人工海水样品中目标物的加标回收率为92%~106%,相对标准偏差(rSd,n=6)为1.2%~7.7%。该方法一次进样可在13 MIn内完成分析,具有操作简单快捷、无污染等优点,能满足近海海水中nO2-、nO3-、PO34-的定量分析要求。Using on-line pre-chlorine and sulfate removal technique,a rapid and direct method was established for the simultaneous determination of nitrite-N,nitrate-N and phosphate-P in seawater by ion chromatography(IC) with suppressed conductivity detection.In this method,an IonPac AG23 column was used as the enrichment column,an IonPac AS23 column with high capacity as the analytical column,and KOH solution as the eluent for gradient elution produced by an eluent generator on-line automatically.The results showed that the determination of the targets was not interfered when a seawater sample diluted 5 to 10 times was directly injected.The method detection limits(MDL) of nitrite-N,nitrate-N and phosphate-P were 0.3,0.4 and 0.2 μg/L respectively,under the conditions of 500 μL sample volume and 1 mL/min elution rate.The linear ranges of nitrite-N,nitrate-N and phosphate-P were 10-500 μg/L,14-680 μg/L and 3.4-170 μg/L respectively,and the correlation coefficients(r) were all greater than 0.999 0.The average recoveries of the 3 analytes spiked in a sample ranged from 92% to 106% with the relative standard deviations(RSDs,n=6) of 1.2%-7.7%.The whole sample analysis process can be completed in 13 min.The method has the advantage of simple operation,reagent-free and pollution-free,and can meet the quantitative analysis requirements of seawater.国家海洋局第三海洋研究所基本科研业务费专项资金项目(海三科2008002);中国极地科学战略研究基金项目(20080222
