    众所周知,农业产业化企业在我国现代农业建设中扮演着举足轻重的角色,然而普遍存在的人才短缺问题却逐步成为该行业发展的阻碍。YX食品公司作为福建省的农业产业化龙头企业,面临同样的人才瓶颈,如何突破瓶颈得以继续生存和发展成为企业迫切需要解决的问题。人才梯队建设是战略性人力资源管理的一项有力举措,近些年备受企业亲睐,然而在研究方面还略显不足,因此本文以YX食品公司为例建立人才梯队,一方面希望对该公司甚至整个行业的人才问题有所帮助,另一方面也希望丰富该领域的研究。 在企业能力(资源基础观、核心能力、动态能力)、战略性人力资源管理、人力资本、岗位胜任力等理论的指导下,本研究结合YX食品公司的实际情况进行...As we all know, Agricultural industrialization enterprises play an important role in the stage of modern China agriculture.However, the shortage of talents has gradually become an obstacle to the development of the industry. As one of the Fujian's agricultural industrialization leading enterprise, YX food company are also faced with the same problem. How to break this bottleneck to survive and dev...学位:工商管理硕士院系专业:管理学院高级经理教育中心(EMBA项目)_高级管理人员工商管理硕士(EMBA)学号:X201115628

    针对gdH(grOuP dIffIE-HEllMAn)方案中节点可能成为系统的瓶颈以及计算复杂度、通信代价和存储复杂度远高于某些集中式方案等缺陷,提出并实现了一种基于优化gdH协商的高效安全的动态群组密钥管理方案,并对其安全性进行了证明。通过对计算量和通信量进行分析比较表明,优化gdH协商协议具有很大的优势,并且能够快速产生或更新组密钥,具有很强的实用性。There are some defects in GDH(group diffie-hellman) scheme,such as the node that may become the bottleneck of the system,and the computational complexity,cost of communications and storage complexity that are much higher than some centralized group key management program.An efficient and secure dynamic group key management scheme based on optimized GDH is proposed and implemented and its security is proven.The optimized GDH consensus agreement has great advantage than GDH by comparing and analysing the volume of calculating and traffic.At the same time,the optimized GDH consensus agreement can quickly produce and update group key,and it owns highly practicability.国家自然科学基金资助项目(60873179);广西教育厅科研资助项目(200707LX196

    针对传统基于人类视觉系统特性的空间域与变换域相结合的水印算法中嵌入信息量小、嵌入位置定位及检测准确率低和算法运行速度慢等缺陷,提出并实现一种基于量子进化算法(QEA)的快速水印新算法。仿真实验结果表明,新算法不仅生成水印图像的速度快,而且对各种攻击具有良好的敏感性和鲁棒性。新算法在应用中有较大的灵活性,并且具有可嵌入信息容量大、运算速度快和可操作性强等特点。There are limitations such as smaller embedded information capacity,lower accurate rate for positioning embedded location and detection and slower running speed in traditional watermarking algorithm which combines spatial domain and transform domain based on characteristics of human visual system.A quickly-speed running watermarking algorithm based on quantum evolutionary algorithm is proposed and implemented.The simulation results show that the proposed algorithm owns not only faster watermark image generation,but also have good sensitivity and robustness for all kinds of attacks.The proposed algorithm is more flexible in application,and it can embed more information and improve the computing speed.The method can be easily operated.国家自然科学基金资助项目(60873179);广西教育厅科研资助项目(200707LX196

    中国东南沿海港口外轮压舱水生物的调查

    Get PDF
    随机选取东南沿海港口的17艘外来船舶(含8条集装箱船和9条散货船)作为监测对象,进行压舱水浮游植物及动物的物种鉴定和丰度测定,并对监测数据进行统计学分析。检出分属于7个浮游植物门类和5个动物门类的309种外来压舱水生物(包括60种赤潮生物)。外轮压舱水生物的分布及生存状态与水样的水龄和盐度相关。船舶压舱水排放是大家熟知的外来水生生物入侵的主要媒介。本调查结果表明,中国东南沿海外来散货船的压舱水排放所具的潜在生物入侵风险比集装箱船更应受关注

    化学物质的大量投入以及元素不能循环导致农田生态系统退化,耕地质量和产量均呈下降趋势,食物链受到污染.本研究从低产田开始,通过秸秆养牛、腐熟牛粪还田恢复地力;以物理+生物方法控制虫害;以人工+机械管理杂草,停用农药、化肥和除草剂,同时不用地膜、人工合成激素、转基因种子生产优质安全食品,并在线上与线下销售.10年的长期实验结果表明,所在村庄农田生态环境改善,减少农药用量58.3%;物理+生物控虫效果明显,每盏灯年捕获量从2009年的33 kg下降到2014年的2.1 kg,下降93.8%;年消耗秸秆1000 t,秸秆利用率从1.1%提高到62.5%.有机肥还田提高了土壤生物多样性,有机果园蚯蚓数量317条m~(-2),而普通果园只有16条m~(-2);大量有机肥还田(75 t hm~(-2)),土壤有机质从实验初期的0.7%提高到2.4%.粮食产量从最初的11.43 t hm~(-2)提高到目前的17.43 t hm~(-2),其中冬小麦(Triticum aestivum)、夏玉米(Zea mays)、大豆(Glycine max(Linn.)Merr.)和花生(Arachis hypogaea Linn.)产量分别超出山东省平均水平42.6%,60.9%,32.2%和38.1%.由于质量好,产品已销售往除西藏以外的30个省、市、自治区,经济效益明显,平均每公顷效益是普通农田的3~5倍,带动所在村庄67户农民从事高效生态农业.本研究可为国家制定生态农业发展规划、精准扶贫、农村环境保护等提供科学依据
