内生型产业集群可持续发展风险及其防范——基于企业家资源的视角

企业家对内生型产业集群的形成与发展具有促进作用,但同时也可能产生“柠檬市场“、同质竞争、企业或企业家群体外迁等发展风险。基于企业家资源的视角,规避内生型产业集群发展风险,需要适当控制群内企业家的效仿性,克服“搭便车“观念,提升集群内企业间的竞争度;弘扬企业家精神,促进企业家创新,提升自主创新能力;营造企业本地化集群发展的创新网络,积极应对群内企业或企业家的“抱团外迁“,提升群内企业的根植性。教育部人文社会科学项目“我国利用外资中比较利益增进机制及实现途径研究”(10YJA790098);江南大学“跨国公司与区域经济发展”创新团队发展计划(2009CXTD02);负责人李晓

The discussion about the relation between justice and the parties to cases- the public ——through Fengze District court's angle of view

法产生于社会的发展进程中，与社会生活有着密切的联系。司法作为一种法律实践活动，与社会生活的距离就更近了。观察司法问题，理应贴近司法实践，从社会生活的实际情况入手。为此，笔者立足于自身工作实际，选择关注当下司法与公众互动关系的课题，通过对当事人-公众进行问卷调查和统计法院审判情况，以丰泽法院的视角探究二者的“应然”及“实然”状况，初步界定二者存在相背离的情形。审视司法、当事人-公众之间的不和谐，可发现其是多方面原因共同作用下的产物，而转型中国大背景下的司法现状，正是制约公众与司法良性互动的关键因素。鉴此，在发现问题及其后的寻找对策过程中，笔者更多地将目光投向司法所应做的努力，除简述宏观方面举措，...The law has been produced in the process of social development, and has been close associated with the social life. As a legal practice, justice has become closer and closer to the social life. To observe the administration of justice, we should be close to the judicial practice and start from the social life of the actual situation. Therefore, the author based on works from the actual situation, ...学位：法律硕士院系专业：法学院法律系_法律硕士(JM)学号：X200512009

Study on the Legal Quality of the Coexistence of Private Lending and Housing Sales Contract

民间借贷案件作为民事案件中最普通、最常见、也是法律关系最为简单的纠纷，长期以来在笔者就职的法院审理的民事案件中占据了四分之一以上的份额。然而，随着经济的发展，民间借贷案件中隐含的法律关系日渐复杂，一张看似简单的借条，它的背后可能是一笔赌债、一份股金、一份买卖合同的货款，甚至是一笔虚假的债务……从2011年开始，笔者在对该类案件的审理中,发现因民间借贷引起的房屋买卖案件由少至多,并有复杂化的趋势,在审理中颇感棘手,由于没有统一的审理规定,可供参考的案例、学说也不多,法官在审理该类案件中只能凭借经验以及基础的理论进行分析判断,但由于认识的不统一,各地法院的判决也不一，相应处理的效果并不理想,这有损...Private lending cases are the most common and ordinary cases of the simplest legal relation out of all the civil cases, therefore these cases made up over 25 percent of all the trials of civil cases in the people’s court which I work in. However, with the rapid economic development, the implied legal nexus behind private lending cases are getting more complicated. The legal cause behind a seemingl...学位：法律硕士院系专业：法学院_法律硕士(JM)学号：X201112010

Synthesis and electrochemical properties of (lithium) manganese oxides as composite cathode materials with high performance

锰氧化物和锂锰氧化物作为锂电池阴极材料，因具有价格低廉、安全性好及对环境友好的特点而被广泛研究。MnO2结构复杂，存在多种晶型，如alpha、beta、delta、gamma等。目前商业化使用的主要为gamma-MnO2，但在放电容量及倍率性能等方面依然有待于进一步提高。对于锂锰氧化物，同样存在多种结构，且不同的结构表现出显著差异的电化学性能，比如，正交型层状LiMnO2（o-LiMnO2）、尖晶石LiMn2O4及岩盐相Li2MnO3等，它们在充放电放电曲线形状，电位平台，电化学容量等方面均为不同。由此，本报告内容立足于研究和开发新型的（锂）锰氧化物材料及制备工艺。 采用水热...Manganese oxide and lithium manganese oxide, as cathode materials, were extensively investigated due to their low cost, safe and environmental friendly issues.

Design of Auto Gain Control Circuit with Two-stage Amplification Feedback

设计了一种适用于移动水声通信接收系统的两级放大反馈自动增益控制电路。该电路采用初级放大—滤波—次级放大的信号调理机制,反馈回路同时对两级放大电路进行增益控制,使输出信号稳定在期望值附近,能有效解决移动水声通信中由于收发端相对距离变化、声传播衰减、信道频率选择性衰落、收发端电路频率响应不均匀等因素引起的接收信号时域和频域起伏变化大的问题。海上试验表明:该电路具有良好的幅度均衡性能,能显著提高水声通信质量。An auto gain control(AGC) circuit with two-stage amplification feedback for the receivers of underwater acoustic mobile communication system was presented.The circuit uses the conditioning mechanism of primary amplification—filter—secondary amplification,and the feedback loop controls gains of the two stages amplifiers,making the output signal be stable near the dexpectations so as to effectively solve the problem of signal fluctuation in the time and frequency domains caused by the distance change between transmitter and receiver,sound propagation attenuation,frequency selective fading of underwater acoustics channel and the uneven frequency response of transmitting and receiving circuit.The sea test shows that the circuit has a good performance at amplitude equalization,and can greatly improve the quality of underwater acoustic communication.国家自然科学基金项目(41376040);; 福建省中青年教师教育科研项目(JA15001);; 国家海洋局海洋公益项目(201505027-2

目的观察健骨颗粒对成骨细胞G_1/S期调控的影响,探讨健骨颗粒促进成骨细胞增殖的作用机制。方法制备健骨颗粒血清组、模型血清组和雌二醇血清组。采用酶消化法培养SD大鼠成骨细胞,健骨颗粒含药血清干预,以模型血清和雌二醇血清为对照。运用流式细胞术检测成骨细胞增殖周期,荧光定量PCR法检测成骨细胞G_1/S期调控蛋白Cyclin E、CDK2、p21和转录因子E2F-1 m RNA的表达。结果 15%的雌二醇血清与健骨颗粒血清干预48 h,成骨细胞增殖速度均明显快于模型血清组(P<0.01);G_0/G_1期成骨细胞比例明显降低(P<0.01),S期、G_2/M期细胞比例及增殖指数则明显高于模型血清组(P<0.01);与模型血清组比较,雌二醇血清组与健骨颗粒血清组能提高成骨细胞Cyclin E、CDK2及转录因子E2F-1 m RNA的表达(P<0.01),而降低p21的表达(P<0.01)。结论健骨颗粒通过调节成骨细胞G_1/S期调控机制,推进成骨细胞顺利通过G_1/S检测点,促进成骨细胞增殖。Objective To observe the effects of Jiangu Granules on the G_1/S phase cell-cycle regulated proteins of osteoblasts, so as to reveal the mechanism of Jiangu Granules in promoting osteoblasts proliferation. Methods The Jiangu Granules-serum group, model-serum group and estradiol-serum group were prepared. Osteoblasts of SD rats were cultivated by enzymatic digestion and intervened with Jiangu Granules-serum, model-serum and estradiol-serum(as control) respectively. The cell cycles were analyzed by flow cytometry, while the fluorescence quantitative PCR was applied to measure cyclin E, CDK2, p21 and E2F-1 m RNA. Results The cell proliferation rates of osteoblasts intervened with estradiol serum and Jiangu Granules-serum for 48 hours were faster than that with the same concentration model-serum(P < 0.01). Compared with the model-serum group, the proportion of osteoblasts in the G_0/G_1 phase were significantly reduced after intervention with 15% of estradiol serum and Jiangu Granules-serum for 48 hours(P < 0.01),while the proportion of cells in S phase, G_2/M phase and proliferation index was much higher(P < 0.01). The expression of cycling E, CDK 2 and transcription factor E2F-1 m RNA of osteoblasts in the Jiangu Granules-serum group and the estradiol-serum group was higher than that of model-serum group(P < 0.01), while the expression of p21 m RNA was lower than the model-serum group(P < 0.01). Conclusion Jiangu Granules-serum can adjust the G_1/S phase cellcycle regulated mechanism in osteoblast, so as to push the cells passing G_1/S checkpoint and accelerate the proliferation of osteoblast.国家自然科学基金资助项目(81473706
