A country known for its longstanding struggle with corruption and dubious governments may not be the obvious venue for a socio-economic revolution that is expected to play an important role in the elimination of global poverty. However, Paraguay, an ??island without shores??, as the writer Augusto Roa Bastos once described it, is home to one of the world??s most innovative social enterprises??the Fundación Paraguaya. While its achievements and success are the result of a team effort, its remarkable development can be largely attributed to Martín Burt, the founder and chief executive. We study the case of Fundación Paraguaya??the first and longest-running non-governmental organisation in Paraguay??with two primary research objectives: (1) to analyse the organisation??s pioneering way of solving social problems under difficult socioeconomic circumstances and its increasingly global outreach to eradicate poverty; (2) and to analyse the responsible leadership of Martín Burt. 相似文献

归化和异化是翻译中的两种主要策略,对这两种策略的选择历来是翻译界争论的焦点之一。本文从探究中国“龙”翻译成“dragón”是否合适出发,主要从汉语俗语的西译入手来浅析这两种策略在汉西翻译中的运用,以期对翻译工作能起到一定的借鉴作用。 相似文献

当运行Windows NT的PC服务器越来越多地进入企业计算环境,并开始承担关键任务的计算时,最需要关注的问题是: ·服务器支持大型,更加复杂,更多样化的解决方案的能力;适应数据库的增长的用户数量不断增加时的处理能力,一个伸缩性能良好的平台应该根据需要的改变易于扩展系统能力。(无论是纵向还是横向能力的扩充),存储容量,内存,输入/输出(O/I),以及和相关环境的互连能力。·停机时间或系统故障对企业来讲都会因失去的时间和损失的收入而增加运行成本,甚至使公司置于风险之中。所有业务必须平衡停机的损失和计设一个新系统的开销,使其减至最小或根本上消除停机时间。·管理分布式环境本来就比管理集中式环境困难得多,更何况PC服务器的关键任务的环境中使用,因而要求其具有对故障状态的可见性和快速响应。 SAM概念 相似文献

As a fast-rising country, the state of energy consumption in China is significantly different from that in the developed .world, which has been using electricity of a relatively stable quantity for years. In China, however, the ever-hungry electricity demand requires at least 7% annual increase to meet the need of ballooning GDR According to the Annual Report on China's Energy Development (2009), up till the end of 2008 the total installed capacity of electricity has reached 790 million kW, including nearly 100 million kW newly developed in 2008 and a similar increment in 2007. Take Japan as an example, one of the TOP 10 electricity consumers in the world, with around 200 million of installed capacity. It seems that in mere two years China has built so many power plants that are enough to serve the entire Japan. 相似文献

行列式的计算是线性代数中的难点、重点,特别是n阶行列式的计算,大多是利用行列式的性质将所求行列式进行变形、化简进而找到较为简捷的办法。本文通过对几个典型n阶行列式的求解,分析了在计算n阶行列式时如何运用行列式的性质,其中的分析思路可以启发学生在计算(证明)行列式时能够灵活运用行列式的性质。 相似文献

本文提出了一元n次方程的极限解定理和计算法则。并举例说明了这一法则在取样锁相环稳定性分析中的应用。我们在研究稳定性一类的极限解等问题时,有时会遇到当β=β_a时,a_u(β_a),a_(n-1)(β_a),…,a_1(β_a)和a_o(β_a)都等于0。方程: a_n(β)x~n+a_(n-1)(β)x~(n-1)+…a_1(β)x+a_0(β)=0是这样的一个不定式: 0x~n+0x~(n-1)1…+0x+0=0本文提出的一元n次方程的极限解法,就是着眼于研究当β→β_a时,上述方程的极限情况。 相似文献

为了扩大802.11n无线产品的覆盖范围,设计了一款符合802.11n标准的2.4 GHz高线性
功率放大器。在该功率放大器的设计中采用了双路均衡功率合成技术和差异化加速开关技术
,在提供高功率输出的同时满足了802.11n的误差向量幅度(EVM)的要求,尤其是实际应用
中的动态EVM。测试结果表明,该功率放大器回退7 dB后的线性输出功率为27 dBm,此
时的EVM为-30 dB,合成功率输出为29.5 dBm。该功率放大器可广泛用于无线局域
网中,与各种类型的无线AP直接匹配使用,提高其覆盖范围。 相似文献
