The Research of Differentiated Strategy in Television Media Industry

“自古不谋万世者，不足谋一时；不谋全局者，不足谋一隅。”时至今日，电视传媒产业化在我国已经走过10余年的时间，然而,大多数的电视传媒竞争主体却缺乏整体的经营战略管理意识，因此，对我国的电视传媒业进行研究，深入开展电视传媒产业经营管理理论与实践领域的相关课题研究就显得尤为重要。 本文以战略管理理论为基础，首先运用波特竞争五力模型，对我国电视传媒业的产业结构进行分析。根据波特理论，决定电视传媒业的行业竞争状态和赢利能力的有五种基本竞争力量，即现有竞争对手的竞争、潜在竞争者的威胁、替代产品的威胁、供应商的议价能力和购买者的价格谈判能力，本文通过对这五种力量的分析，充分认识了目前我国电视传媒行业的竞...There is an old Chinese saying that "the people do not consider about the whole history,will not succeed in the moment; the people do not concern about all situations, will not dominate a situation". To date,the TV media industry has existed in China for over ten years, however, most of the subjects of TV media are lack of the whole consciousness of business strategy management. Therefore, it is c...学位：会计硕士院系专业：管理学院会计系_会计学学号：X201015705

Tissue Culture Technique of Acacia mangium Elite Trees

作者简介: 黄烈健( 1971—) ，男,博士,副研究员,研究方向为林木遗传育种与森林培育，电话: 020-87033463,E-mail: hlj@ ritf.ac.cnTaking Acacia mangium elite trees as explants，the tissue culture technique system for dormant bud of 3-5 year-old elite trees was established． The system includes the germination-inducing of the dormant buds，the multiplying of shoots，the rooting of adventitious shoots，and the pre-treating and transplanting of seedlings． The medium MS + Sucrose 30 g·L－1 + BA 0.5 mg·L－1 + NAA 0.1 mg·L－1 was used for inducing the dormant buds; the medium MS + BA 1.0 mg·L－1 + NAA 0.05 mg·L－1 was used for multiplying; while the medium 1 /2 MS +IBA 2.0 mg·L－1 + NAA 0.5 mg·L－1 was used for rooting.The results revealed that it was viable to producing field seedlings with micropropagation.Although the branches with dormant buds harbored many kinds of microbes and the adventitious shoots were not easy to root，20% to 30% healthy germination could be yielded and the rooting rate of adventitious shoots could be higher than 85%.Pretreated with ABT powder ( rooting hormone) ，both the rooting rate and survival rate of adventitious shoots were nearly 100%．国家“十一五”科技支撑计划项目(2006BAD01A15-5,2006BAD32B010-3); 农业科技成果转化项目(2009GB24320482

Nonlinear Dynamic Analysis in Voices Signal from Patients with Vocal Polyps and Cysts

目的比较传统扰动方法与非线性动力学方法分析正常人、声带息肉和声带囊肿患者嗓音信号的结果,探讨非线性动力学方法的临床应用价值。方法对20例正常受试者、26例声带囊肿患者和29例声带息肉患者,分别应用传统扰动方法测量声学指标频率微扰(JITTEr)、振幅微扰(SHIMMEr)和应用非线性动力学方法重构相空间、计算关联维(d2)等,比较其结果。结果正常受试者嗓音信号的JITTEr、SHIMMEr和d2值均低于声带息肉和声带囊肿患者,差异有统计学意义(P0.05),声带息肉和声带囊肿患者嗓音信号的重构相空间复杂程度相似,但比正常人复杂。d2值在rOC曲线下的面积小于JITTEr和SHIMMEr值,其中5例患者嗓音信号不能应用扰动方法分析,而非线性动力学方法均可分析。结论扰动方法和非线性动力学方法对声带息肉和声带囊肿患者异常嗓音均有诊断价值,扰动方法的特异性优于非线性动力学方法,但其对信号的规则性要求较高,适用性较低,非线性动力学方法可作为扰动方法的重要补充。Objective To assess and compare the abilities of traditional perturbation methods and nonlinear dynamic methods to describe voice from normal subjects and patients with vocal polyps and vocal cysts.Methods Perturbation measures of jitter percent and shimmer percent,nonlinear dynamic measures of phase space reconstruction,and correlation dimension(D2) were applied to analyze the voices of 75 human subjects.Results There was a significant difference in jitter,shimmer,and D2 between normal and pathological voices(P0.05).The phase space reconstruction was similar between patients with vocal polyps and patients with vocal cysts,but it was more difficulty than that of normal subjects.The area under the ROC curves for D2 was less than the areas for jitter and shimmer.5 patients' voice signals could be analyzed by nonlinear dynamics methods but not by perturbation methods.Conclusion Both nonlinear dynamic and traditional perturbation measures could separate normal and pathological voice.Perturbation measures were superior to nonlinear dynamics in distinguishing pathologies but showed a higher rate of signal and lower adaptability.Nonlinear dynamics can be used as an important supplement to perturbation measures.国家自然科学基金项目资助(NSFC81070773
