2008年8核心处理器的诱惑——解析Intel最新处理器发展

在新一届的IDF上，Intel展示了其最宏伟的x86架构改进计划，涉及20余款应用于不同层面的核心，其公开的路线图直接规划到了2008年，甚至2009年的相关动向也已经有了提及。于业界而言，这无疑是一枚重磅炸弹，将给未来带来深远的影响。[编者按]     

GPU替代CPU？——崛起中的GPGPU应用

自从GPU于2001年进入可编程时代以来．“能否把GPU丰富的资源应用到通用计算中去”一直是业界讨论的话题，毕竟通用计算设计的CPU实力有限．而在进行纯CPU操作的时候．有浮点专长的GPU在一边睡大觉着实是种浪费。早在DX8时代．就有研究机构尝试用Ti4200显卡进行数据库操作．进入DX9时代以后，此类研究就更多了．不过所有的尝试，都不像一个月前斯坦福大学的Folding@HOME那样贴近广大用户．可以亳不夸张的说，在X1000显卡上实现Folding@home是GPGPU走向大众应用的一个里程碑。[编者按]     

A change management framework for macroergonomic field research

With the proliferation of macroergonomic field research, it is time to carefully examine how such research should be managed and implemented. We argue that the importance of attending to high-quality implementation of field research is equal to that of methodological rigor. One way to systematically manage the implementation process is to adopt a change management framework, wherein the research project is conceptualized as an instance of organization-level change. Consequently, principles for successful organization-level change from the literature on change management can be used to guide successful field research implementation. This paper briefly reviews that literature, deriving 30 principles of successful change management, covering topics such as political awareness, assembling the change team, generating buy-in, and management support. For each principle, corresponding suggestions for macroergonomic field research practice are presented. We urge other researchers to further develop and adopt frameworks that guide the implementation of field research.     

怎样才能突破封锁、隐身BT载？

为了有效控制BT下载流量,网管一般都会用软件屏蔽BT客户端的端口（默认6881-6889）和常用BT服务器,这样你在单位局域网内就不能使用P2P工具进行BT下载了。有些场所局域网内允许BT下载,但速度却非常慢,如果想突破这类限制,应该怎么办呢？如果在BT下载时又不想暴露自己的IP,希望能进行隐身BT下载,又该怎么办呢？     

口述下载那些事儿

不管下载软件背后有多少破事儿,要追看美剧,它们还仍然是我们的第一选择. 和大家一样,我也是美剧迷,每次出新剧,也和大家一样激动万分地等待,第一时间挂夜下载.不过,和大家不一样的是,你们用别人写的软件下载,我用自己写的软件下载.     

Metal/dielectric transmission interference filters with low reflectance. 2. Experimental results

The successful fabrication of metal/dielectric multilayer filters requires not only accurate control of the individual layer thicknesses, but also a good knowledge of the optical constants of the materials used in the filters. In the case of metal films, it is also essential to know whether any transition layers are formed at the interfaces and, if so, how their thicknesses and optical constants depend on the deposition conditions. An automatic, real-time process control, magnetron sputtering deposition system was modified to permit the manufacture of metal/dielectric filters using optical monitoring techniques. To illustrate the performance of this system, two bandpass filters, a short-wavelength pass filter, and a neutral density filter were produced, all having a low reflectance for light incident on one side. The metal layers used in these filters consisted of either Ni or Ag. TheAg films could be protected from the O(2) plasma using thin Ni or Si films. Good agreement was obtained between the calculated and measured spectral transmittance and reflectance curves.     

Toward a theoretical approach to medical error reporting system research and design

The release of the Institute of Medicine (Kohn et al., 2000) report "To Err is Human", brought attention to the problem of medical errors, which led to a concerted effort to study and design medical error reporting systems for the purpose of capturing and analyzing error data so that safety interventions could be designed. However, to make real gains in the efficacy of medical error or event reporting systems, it is necessary to begin developing a theory of reporting systems adoption and use and to understand how existing theories may play a role in explaining adoption and use. This paper presents the results of a 9-month study exploring the barriers and facilitators for the design of a statewide medical error reporting system and discusses how several existing theories of technology acceptance, adoption and implementation fit with many of the results. In addition we present an integrated theoretical model of medical error reporting system design and implementation.
