  • The ways in which we consume and pay attention to information are changing. The changes are not minor, they are big and profound.
  • Today we have successfully replaced attention with what Linda Stone coined and Marc Orchant recently wrote about: Continuous Partial Attention.
  • There are two major axis that cause inattention - the amount of information and the interrupts.

  • There are many things you can do to regain control over your attention and shut out the distractions. But the simplest thing you can do is to turn off the alerts and alarms when you're working on projects. I said simple, I didn't say easy.

科学网-学历的贬值 - 0 views

教育

shared by Roger Chen on 04 May 08 - Cached
  • 物以稀为贵。随着高等教育的日益普及，学位证书就显得不那么珍贵了。这是因为，虽然在某种意义上可以将教育看作投资，但经济增长与教育经费的增长并不直接成比例，因此，在高等教育迅猛发展的时期，对于毕业生的雇佣者来说，社会上的大学毕业生越多，每张学位证书所体现的经济价值便越小。这是经济意义上的学历贬值
  • 随着经济增长，人们的物质需要得到较好的满足后，社会对只有受过高等教育方能满足的高级工作的需求也会增长，于是，用于正规教育的经费得以增加。高等教育一方面对求学者提高地位有好处，另一方面替雇主筛选了人材。可是，学位证书越颁越多，其效果就像通货膨胀似的。结果，教育作为高级工作的敲门砖的保险系数越来越低，
  • 赫施认为，学位证书的“通货膨胀”效应在两方面造成了社会性浪费；第一，大量教育经费实际上是用来淘汰、筛选人的，而不是积极地培养人的。第二，获学位的人很多，就必然有一部分学位获得者不得不屈尊俯就一些不能充分用其所学的工作，因此情绪低落，满腹牢骚，工作效果也不好。但这种浪费很难避免，因为，随着劳动力的平均学历水平的提高，学历较低的人就感受到很大的压力，即使为了在职业阶梯上站稳脚跟，他们也要力图提高自己的学历水平，这就造成了对高等教育的一种虚假的需求。于是，形成了恶性循环。

    A newly published patent application from Microsoft takes an interesting spin on presenting information, pulling together news from a mix of sources to present topics in storylines, and providing ways to have that information delivered to us over computers, smart phones, watch interfaces, and in other ways.

  • McLuhan常常被翻译成麦克卢汉，其实这个地方h不发音，所以也有人翻译为麦克卢恩。既然如此，我觉得还不如翻译成麦克乱，因为大众传播时代的特点就是乱。

  • The standard measure scientists use to judge the importance of scientific papers is a simple citation count. That is, how many other papers cite the paper in question? While this measure has its merits, it has one fundamental flaw - not all citations are equal.
  • Numerous authors/bloggers have advocated using a PageRank-like index for quantifying the importance of papers or journals
  • To represent the web we use a directed graph, where the edges carry a direction.
  • ...4 more annotations...
  • The goal of the PageRank algorithm is two-fold. We wish to construct a measure of relevance that, first, is related to how many incoming links a site has, and second, what the importance of the source of those links was.
  • Well scientific papers can be mapped to a graph in a similar way to web-sites. Specifically, vertices in the graph would represent papers, and edges citations. The PageRank algorithm can be applied out-of-the-box.
  • First of all, one could discount self-citations from the index
  • A second variation that one might try is to add a time bias when calculating the index, such that links from more recent papers carry more weight than from older papers.

科学网-博士生应接受一个完整的研究过程训练（转发） - 0 views

  • 杨乐认为，博士生阶段有两项任务，一是要打下较广博的基础，二是在导师的指导下，受到一次完整的研究工作的训练，做出合格的学位论文。
  • 第二项比第一项更重要，更能直接反映出研究水平的高低。也就是在导师的带领下，完成一个研究工作全过程的训练，比如从确定课题、阅读文献、攻克难关、扩大战果、撰写论文，这样一个完整过程
  • 过去，教育部曾规定，博士论文要超过100页。杨乐说，作这样的篇幅规定也许不一定适合，但它的道理是博士论文并不全部都是创造性的成果，其中有相当篇幅是对选题所在领域或方向的一个总结，相关文献要念得很透，消化后再用自己的观点和语言将这方面的工作做一个很好的总结；同时，博士论文也应该包括创新成果，因此，博士论文并不完全相同于写一篇研究论文。
