杠杆治理、独立审计与代理成本——来自财务困境上市公司的实证发现

本文以2000-2005年我国财务困境上市公司为样本,经实证研究发现:(1)随着负债水平的上升,公司代理成本将显著增加,其中非国有控股公司上升幅度更大;(2)独立审计在一定程度上能够降低公司代理成本,表现为被出具持续经营审计意见的次年,公司代理成本有显著降低;(3)对于非国有控股公司,如果独立审计机制与杠杆治理机制同时存在,则会产生积极的协同效应,该协同效应可以大大降低负债的边际代理成本,但在国有控股上市公司中没有发现该协同效应。国家自然科学基金项目(70802056)“中国资本市场持续经营审计意见行为:信息解读、自我预言实现及其决策机制研究”;国家社科基金项目(07BJY027)“投资者保护、公司治理与我国证券市场资源配置效率研究”的阶段性研究成

对铁路运输企业基层站段实行全面预算管理的现状和对策探讨

铁路运输企业开展全面预算管理，优化整合财务资源。但是，在交通运输市场竞争加剧、设备更新等情况下，铁路运输企业处在运输收入增幅变窄、刚性增支因素变多的严峻经营环境中，全面预算管理在实现企业资源优化配置方面的作用越发重要。全面预算管理作为整合内部资源、强化内部控制的重要手段，已成为了铁路企业转型发展和走向精细化、现代化管理的必由之路。</jats:p

开源RTOS T-Kernel在Blackfin处理器上的移植

随着嵌入式计算技术的飞速发展,多种功能强大的微处理器和相应嵌入式操作系统也相继问世。选择合适的嵌入式操作系统和处理器平台进行移植成为嵌入式开发的重要技术环节。本文介绍了开源嵌入式实时操作系统RTOS(Real Time Operating System)T-Kernel和Blackfin(BF)533处理器及其开发环境VisualDSP++4.5Environment,给出了中断管理、任务切换和系统调用入口三个模块的移植方法,并讨论了相应的系统稳定性和实时性测试方法。日本T-Engine组织推出的T-Kernel RTOS拥有高实时性、小体积的内核,并强调对底层处理器全面封装;ADI Blackfin系列微处理器同时具有DSP和MCU的特点,非常适合于移植RTOS。因此T-Kernel在BF533上的移植是一个典型的开发应用实例,其移植分析方法对于其他嵌入式RTOS移植也具有参考价值

Enzyme - linked immunosorbent assay(ELISA) quantitative analysis for paralytic shellflsh poison (PSP) in shellflsh

采用酶联免疫法检测菲律宾蛤仔(Ruditapes philippin)肌肉中麻痹性贝毒(Paralytic shellfish poison,PSP)含量,通过优化实验条件,规范操作程序,确立了检测流程。试验表明以标准PSP 为参照,该检测方法平均灵敏度可达2μg/kg,标准溶液测定的变异系数2.00%-7.66%,样品精密度测试的变异系数为2.82%-8.40%,平均添加回收率达85.35%,表现出快速、灵敏、可靠等特点,适于常规工作中麻痹性贝毒的快速筛选检测。Quantitative analysis of Paralytic Shellfish Poison (PSP) in Ruditapes philippin was carried with Enzyme -Linked Immunosorbent Assay (ELISA) . It showed that: the mean detection limit was 2μg/ kg, mean recovery rate was 85.35%, and coefficients of variation of 2.82% - 8. 40% indicated that the screening method is rapid, reliable, and sensitive.厦门市海洋与渔业局资助项

T-Kernel是日本T-Engine组织推出的开源免费的嵌入式实时操作系统(RTOS),以其强实时小体积内核著称。本文针对T-Kernel在Blackfin处理器(BF533)上的移植过程进行了分析,给出了中断管理,任务切换和系统调用入口的实现方法,并进行了稳定性和实时性测试,保证了移植系统的性能

Analysis of inosine monophosphate in six fish musculatures

采用高效液相色谱技术,在国内首次测定了条纹斑竹鲨(Chilocsyllium plagiosum)、大黄鱼(Pseudosci-aena crocea)、鳜(Siniperca chuatsi)、青石斑鱼(Epinephelus awoara)、牙鲆(Paralichthys olivaceus)和乌塘鳢(Bostrichthys sinensis)等6种鱼类新鲜和冻存肌肉组织中肌苷酸含量。结果表明:(1)不同鱼类肌肉组织中肌苷酸质量比不同,牙鲆新鲜肌肉组织中肌苷酸质量比最高,为4.214 mg/g,其余5种鱼类为2.365~3.634 mg/g。(2)10 d冻存试验中,经-70℃超低温冻存,6种鱼类冻存肌肉组织中肌苷酸质量比均高于新鲜肌肉组织,大黄鱼肌肉组织冻存1 d肌苷酸质量比达最大值,鳜肌肉组织冻存10 d肌苷酸质量比呈上升态势未出现最大值,其余5种鱼类肌肉组织肌苷酸质量比均在冻存第5天达到最大值。长时间的冻存将会降低食用鱼肉中肌苷酸质量比,导致鲜味下降,但经1周左右短时间的冻存后可明显提高鱼肉中肌苷酸质量比,增加鲜味,提高食用价值。Inosine monophosphate(IMP) contents of six fishes, Chilocsyllium plagiosum,Pseudosciaena crocea,Siniperca chuatsi,Epinephelus awoara,Paralichthys olivaceus and Bostrichthys sinensis,collected in Xiamen fishery market were tested by high-pressure liquid chromatography(HPLC) in the present paper.The results showed:(1) IMP amounts of the musculatures varied with the different fishes,and the IMP quantity(4.214 mg/g) in fresh sample of P.olivaceus was higher than those in others(2.365～3.634 mg/g).(2) IMP contents of six pieces of fish meats frozen in-70℃ were all higher than those of fresh ones in 10 days cold-storage.IMP of frozen samples in P.crocea reached tiptop after 24 h cold storage,that of S.chuatsi still got up by the end of the test,while those of the other fishes got the highest at the 5th day.IMP contents of fish meat reduced in a longtime cold-storage and resulted in lowering down fresh.But the IMP contents obviously increased and the fresh and edibility seemed improved in coldstorage in the first week.国家863计划项目(2002AA603021);; 厦门市科技项目(3502Z20063022
