今天读到两则有趣的报导。一则强调地理在当今信息时代重新显示出其重要性 (A sense of place, http://www.economist.com/news/special-report/21565007-geography-matters-much-ever-despite-digital-revolution-says-patrick-lane)，另一则则表示地理优势在信息经济新时代已经越来越不明显 (亚马逊VS沃尔玛：信息经济时代零售霸主逆战，http://www.21cbr.com/html/topic/201210/28-10535.html）。
第一篇文章回顾了历史上对地理的三种看法。第一种是出现在90年代的end of geography。由于互联网的共享性，全世界任何一个角落的人理论上都能享受到共同的资源。在网络上不再有距离的概念（the death of distance)。第二种概念更加极端，认为网上的虚拟世界可以完全替代真实世界。我想这是在21世纪初随着SecondLife这样的cyberspace兴起时的思潮。在这样的虚拟世界里用户可以模拟现实生活中的几乎一切事情，甚至有自己的货币。然而这种想法被证明是不现实的，虚拟世界不可能脱离现实存在，比如虚拟的货币仍需要通过真实货币来兑换。
第三种认为现实世界会影响网上的行为。正如地学第一定律所述（Everything is related and things closer in space are more related），用户更关注身边的事 (local)。随着移动设备的普及和地理定位技术的成熟，企业提供这种local service成为可能。从这个角度讲，geography成为local business越来越重要的因素。
第二篇文章比较了亚马逊和沃尔玛两个零售业巨人。后者是传统的线下销售，前者是这个信息时代特有的产物。近年来亚马逊的营业额逐年上涨，剑指行业老大沃尔玛。沃尔玛通过数十年努力建成的由土地、建筑构成的实体网络正在遭遇前所未有的危机。网络商店的出现，让传统零售业的法宝 location, location, location显得不再那么重要。而目前，两家公司都采取着相似的战略：线上线下的有机结合。
曾经有人疑惑，网络到底需不需要有距离的概念？这涉及到一个问题，即地理到底应该在多大程度上与网络、与信息结合？这里面涉及一系列问题，包括人对（地理）信息的需求，人感知（地理）信息的偏好和习惯，（地理）信息系统如何满足人的认知习惯等等。作为地理信息科学的研究人员，我觉得我们的时代马上到来了。

Academia is not the only option for PhD
It has been puzzling me all the time, even after I've come here for PhD, that how is PhD accepted in industry. There are many negative sayings about PhD: "Permanent Head Damaged", because PhDs are usually stubborn and confined in a narrow field; old aged, and often immersed in old fashioned papers published decades ago; idealist, whose theories and ideas are built in the lack of technological support; etc. So it's exciting that today there is a doctoral career exploration workshop, with most of the speakers graduating from doctoral programs of Penn State. And I should say, I really learn a lot. Or to be more exact, I actually knew those stuff. I simply got lost after I dived into the mess. And the speech today helped me out, and reminded me of my strength as a PhD.
So why does a company hire a PhD. Apparently the company has a different expectation for PhD. The company won't pay a PhD to program. Some of the things that a PhD is expected might be:
1. Direct a team. Think of ideas in what directions should your team go. Be creative and innovative.
2. Theorize your product. Apply the theories in your domain to practice. It's important that your products are well theoretically founded, so that it is convincing for investors and customers. Be rational and persuasive.
We should be aware that the graduation program is not to get us damaged, but to get us fully prepared.
Keep on asking ourselves internally what is my goal, what is my value, what is the need of the world. Find a joint point of the three aspects, and we can make a difference.
For me, I actually already have a very clear path. I'm to study the cognitive aspect of computer systems. The problem for me is what I can do to improve the usability of a system. And I would start from how people perceive information, and apply that understanding to the design of systems. As I have a GIS background, I may focus on GIS as the study case, but I should also not limit myself in GIS. Therefore my strength should definitely not be interface design or system programing, but to provide guidelines to those guys, in a theoretical level, and suggest evaluation methods before the final product is issued to the public.
So what I need to do in the first step is to enrich myself with the theories of human cognition. Also to leverage my strength, I should apply those theories to the GIS field. So a deeper understanding of GIS users and their thinking, reasoning, and behavior is required.
Finally, building a friend network is as important as academic achievement. I should not lock myself in the lab all day long any more. I should get out, talk to people in other areas deeply, and get inspiration.
