并购与种子产业发展

并购是现代经济史上一个十分突出的现象,现代种子产业的发展就是一部种子企业的并购史。从微观层次上看,并购是企业发展和追逐利润的内在要求,是实现企业扩张和资本集中的快速有效形式,从宏观层次看,是产业结构调整,合理配置资源的手段。从并购这一企业行为对市场结构和产业发展影响的角度,对世界种子产业发展中的并购过程和并购效应进行实证分析,证实了国际种子产业的并购实践对现阶段国内种子产业的借鉴意义。     

Organizational innovation as an enabler of technological innovation capabilities and firm performance

This study assesses the relationship between organizational innovation and technological innovation capabilities, and analyzes their effect on firm performance using a resource-based view theoretical framework. The article presents empirical evidence from a survey of 144 Spanish industrial firms and modeling of a system of structural equations using partial least squares. The results confirm that organizational innovation favors the development of technological innovation capabilities and that both organizational innovation and technological capabilities for products and processes can lead to superior firm performance.     

Land acquisition and irrigation in Nigeria

With land as Nigeria's most important asset, successive local and central governments have sought to control the acquisition of land so that it may be put to optimal use by the population of 70 million. The author looks into the theory of land acquisition and its history in Nigeria, with special reference to a number of irrigation projects. He examines in depth the actions and attitudes of the developers in several cases and notes a lack of consistency and consideration on their part. The author records the resulting opposition to any irrigation project due to the injustices such schemes have engendered in the past. He suggests a set of guidelines to bring an Improvement in relations between land-owners and the authorities, so that development projects are not held back and finally implemented in an atmosphere of hostility.     

国有企业海外并购中的经济安全问题研究

随着经济全球化以及贸易自由化趋势的不断加强,中国企业对外直接投资高速增长,尤其在全球经济危机之后,对外投资已经成为我国企业实现全球布局的重要环节。国有企业作为对外投资企业的主力军,较多地采用了并购的形式,然而,由于国际金融市场的不确定性以及我国社会主义市场经济体制还有所缺陷,使得国有企业在海外并购活动中的经济安全问题一直是一个不能忽视的问题,所以对于这一系列活动风险的防范也就显得尤为重要。因此,加深对这一问题的研究,对于国有企业的海外并购具有重要的意义。

低信噪比环境下短扩频码捕获性能的改善

介绍了低信噪比环境下基于FFT的扩频码捕获技术,提出了在相同累加段数情况下提高性能的方案。作为提高相干增益的两种方式,相干累加和非相干累加各有优缺点,在一定的数据长度内合理地设计累加方式对提高捕获性能大有帮助。基于两种累加方式的性能介绍了一种两路非相干积分的累加方式。对于GPS信号,在低信噪比的环境下的仿真证明,在一定长度下优化后的累加方式相比非相干累加和普通混合累加方式能够得到更好的捕获效果(更高的检测概率)。     

基于DSP的高动态接收机载波捕获跟踪技术

介绍了高动态GPS接收机的码捕获与载波跟踪的原理,设计了一种基于高速数字信号处理(DSP)技术的PLL FLL环混合全数字高动态载波跟踪技术方案,同时给出了一种在连续高动态下载波跟踪算法即基于交叠离散傅里叶变换的频率跟踪算法(ODAFC),并对此算法进行了仿真验证.仿真结果证明了该算法的正确性.
