April 30 C'est difficile...刚开始,觉得看paper,整理思路,引证,写essay,是最困难的,花了几个月;后来设计调查问卷,翻译,修改使通顺,进行调查,也是困难的,花了一整个月;现在看来,数据处理,仍然困难。
388份数据,SPSS,PLS,EXCEL,三种软件之间的转换,无数个数字的处理
Descriptive analysis, factor analysis, Linear Regression, PLS loading and weight, significance, beta,second order factor...
头大了
所谓academic research原来绝对不是简单的事情,它是脑力与体力的高强度结合...需要researcher全心devote...以后一定只做脑里活,体力活全部交给所谓的Research Fellow or Research Assistant, 欧啦啦
不好的消息是提交给PACIS的其实很不完善的research-in-progress被拒了;好消息是不用因此而去新西兰了,过两天完全写好后再投ICIS说不定就被收了,可以去加拿大了。年轻就是财富,总是充满未知,谁知道呢 April 25 .白色风车 词曲:Jay Chou 白色的风车 安静地转着 真实的感觉 梦境般遥远 甜甜的海水 复杂的眼泪 看你傻笑着 握住我的手 梦希望没有尽头 我们走到这就好 因为我不想太快走完这幸福 很可惜没有祝福 当爱你并不孤独 不会再让你哭 我陪你走到最后 能不能别想太多 会不会手牵着手 晚一点再到尽头 你说不该再相见只为了瞬间 谢谢你让我听见 因为我在等待永远 April 23 啦啦啦今天早上终于结束了操作系统考试

作为四张手写的纸张,一定已经被大妈们当作别人不文明胡乱扔掉的废纸处理掉了...两个月的努力,哎。 April 20 由大山哥的随笔所想到的看到大山哥关于某日“平原游击队”三人众促膝夜谈中我所云厦大与国大计算机教育之比较所做的评论,不觉莞尔。大山哥虽平日自恃不学无术,自号懒人一个,不料竟然武侠小说功底颇深,能将一段乏味之教育评论演绎得如此精彩,也是一种实力。 先看大山哥文章(遵照C语言惯例, ”/* */“之间是我的评论 ): 作为平原游击队成员,一直并肩战斗在操作系统这门课写”任务管理器(Task Scheduler)“ 的学期assignment的第一线上,三人本就相处甚笃,有如此机会,自然不会放过。于是天南海北,大山哥看破红尘地把图像识别统统抛开了,我们也把任务管理器抛开了。 /*

April 16 写完睡觉去~颇有种好几天没睡过觉的感觉
其实是好几天没怎么睡过觉了
看谁比谁更拼命,看谁比谁更出色
PS:奉劝所有学弟学妹,除非对CS超感兴趣甚至有天分这样子,谁也别进School of Computing,否则即所谓“死无葬身”
另看到某小孩博客上几句话很精辟,在此引用一下:

正所谓简短有力,发人深思 April 09 加油加油加油很久没有像今天这样一整天只做一件事情了
睡觉时候总是做噩梦写essay
所以早上七点就起床开始写essay,一直到现在,01:45, 一整天,19个小时
除了吃饭,玩了一小会儿游戏之外,跟小朋友发发短信之外
全部是在自己的一尺书桌的电脑上写essay和do questionnair design
腰酸,背痛,头晕,眼花
颇有些老了的迹象...
然,
XX老矣,尚能饭~~
我要拼命,拼命尽快完善survey,尽快发出去,收集数据,分析
我要拼命在走之前利用这边的一切国内拿不到的资源尽量多地跟导师合作,完成这篇处子作的paper大作
(回去之后才能逍遥自在一小段时间~)
坚信这篇paper之于其涉及到的领域的独特性、创新性和重要性
坚信即便它无法在新西兰的PACIS发表,也必将能够在国际刊物上发表
因为
我站在巨人的肩上
有最锐利的武器(Google Scholar, NUS Digital Library)
最强悍的战友(导师,朋友们)
和自己的大脑,钻研
还有两周就要考试,另外还有一对乱七八糟的小事
总是无法抽出大块的时间很专心的继续essay
没关系
是凛冽的北极寒风造就了维京人 那就让暴风雨来得更猛烈些吧
加油加油加油 April 08 Executive Case Summary 7, regarding to the Case “The FBI and Digital Surveillance: How Far Should It Go?”Ethical concerns about FBI’s authorized and influential power have never been quiet down and have become even more controversial after 2001. Under the Patriot Act put into place after the September 11 attacks, FBI has gained more and broader influences on the surveillances of potential criminals and terrorists to enforce the country’s security.
Both FBI and the US citizens are in ethical dilemmas for this issue because the trade offs between national security and individual privacy is never easy to obtain. It is indispensable for FBI to monitor information flow of potential terrorists or criminals, but under current limitations, their activities fail to fulfill their responsibility while satisfy the public’s needs for privacy. For the U.S. citizens, while they realize the necessity of FBI’s actions to enforce their security, they are also concerned in problems such as over surveillance and intentional or unintentional misuse of its power to intrude individual privacy. Their conflicts mainly come from the trade off between and different evaluations of security and privacy and this is worsened by some of FBI’s failure or scandals, either technically or politically. And the use of electronic surveillance and national security letter are the two issues been brought to attention.
There are various options to deal with the dilemma. One feasible option is to require changes in law to limit FBI’s power on certain actions but this could lead to the loose of national security. Another possible option is to make FBI’s work more transparent to at least the top officers in the federal government which would lower the risk of misusing but may result in inflexibility and over intervenes from the top. Other options include internal improvement of FBI’s working procedures and methods, trying to balance the two sides. In practical, a combination of the options mentioned above from both internal and external perspectives to make FBI’s job more acceptable may be a proper solution.
Ethical and social impacts of the use of modern technology could be significant. Even when it comes to pivotal domain like national security, citizens’ are still concerned of their privacy. Thus for IS managers, it is important to carefully evaluate the ripple effects of IT and perform the ethical principles to be ethically and morally right when adopting technologies. Executive Case Summary 6, regarding to the case “Knowledge Management 2.0” by S. Spanbauer (December 1, 2006) in CIO Magazine (http://www.cio.com/archive/120106/fea_tec.html)Newly developed knowledge management (KM) tools based on Web2.0 are now available and may become a reasonable choice. They adopted ideas like blog, RSS to encourage and foster knowledge sharing, without additional work and much money. In contrast, “traditional” KM tools failed to be widely applied because of its high cost, complexity, and unfriendly user interface.
EMS Documentum is a large set of software which helps manage all kinds of content across multiple departments within a unified platform. Through various software under the same platform, it enables enterprises to manage and share content within organizations and with outsiders. Tangible costs includes large amount of funds to buy the software from EMS and additional IT hardware, maintenance and technical support will be required. Intangible costs consist of efforts on employee persuasion and training on the new system, and long term incentive to encourage knowledge sharing. Although expensive, complicated and not user friendly, the Documentum system is now well established and has been adopted and tested by many large enterprises. EMS also gets a whole basket of services and solutions to help address problems, as long as you have enough money. The newly developed “KM 2.0” tools are web-based, inexpensive and more user-involved because of its Web2.0 features. But they are new and therefore lack of further testing which may lead to privacy, security pitfalls.
The decision on adopting a KM system should be consistent with the business needs. A KM system may contribute to knowledge sharing but it should be people-centric and more attention should be put on the business strategy and the corporate culture. Several factors would be addressed when evaluating the two kinds of KM systems. Whether and to what extent a KM system contributes to the organization’s comparative advantages should be first evaluated. Then whether we have enough funds to buy the Documentum system and related services is important. Further, whether the corporate culture encourages knowledge sharing should be considered because if not, the adoption of a Documentum system would require much political efforts and incentives to get employees on board and then a KM2.0 system is more attractive because of its grass root features. The biggest challenge of KM initiative is to get employees engaged in knowledge sharing. It requires clear incentives and rewards. Employees need to feel beneficial from the process. T-shaped managers can be adopted to foster collaboration and interactions among different units to further assure successful KM. Executive Case Summary 5, regarding to the case “NIBCO’s BIG BANG” by C.V. Brown and I. Vessey (2001) in Communications of Association for Information SystemsImplementing a new enterprise-wide system maybe beneficial but risky as well. More attention on strategy and immense efforts aligning the enterprise resources are needed, to smoothly develop and implement the new system to leverage its benefits.
NIBCO adopted Application Packages from a vendor as its ISD approach. Generally speaking, since the vendor provides the complete set of applications which might have been existed and used for similar problems elsewhere, if the system is installed properly, companies can save time and win substantial payback. However, the disadvantages are also significant. Risks of failure or delaying or beyond budget are high because of the system’s large size and complexity. Companies may have to compromise and change their way of doing business to balance with the new system. There are also problems like vendor switch, lack of intimate knowledge of the system, etc. In initiation, large numbers of business men were involved and 14 months were spent, all in the purpose of identifying the core business processes and problems. SAP trainings were conducted to make team members familiar with the system. Incentive pay bonus and stock options were granted to encourage the team members to work hard and quickly. In development and implementation, business teams, IS department and Change Management cooperated closely to customize the system, build IT infrastructure, and improve communication within the organization. Long hours of training to the employees were delivered. Budget was carefully evaluated throughout the process.
In order to implement quickly to satisfy business demand and avoid suspending without fully applying the systems, NIBCO chose the big bang approach. The challenge was that since they would convert to the new system all in one shot, they need to quickly address and fix problems emerged and help the staff run the systems smoothly. The Go Live date was set shortly before the New Year’s holiday, which would allow more flexibility and time for adjustment. New tactical teams were formed to handle heading up risky areas such as data, customization, helpdesk, etc. Critical success factors: Senior management’s consensus and support; close alignment of business and IT; proper champion involved.
Recommendations: Carefully evaluate whether to reinvent or not; consider whether they can devote sufficient resources and accept the opportunity cost during the implementation; a team of closely cooperated business people, IS staff and proper champion should be formed; prepare to modify organizational structure to accommodate the new system.
April 03 忙里偷闲Sentosa真是不容易,在快要期末考试的时候
有机会纠集一批人出来休一天假
可以暂时放下闷在手中一学期的的一切陈腐
暂时忘记一切忧愁烦恼
全然无我地漂浮在海水中
叫上阿浩,Zhang Hu,又见到野猪、文文,而且终于见到了SMU交流的Lin Yan同学
Sentosa的沙滩 阳光
于是完美的周末,就这样成型~
真该以此为引子,写篇《周末是怎样炼成的》~
Sentosa外景
第一张集体照,一位印度大叔的杰作...
曾经梦里的狮子
装一幅一本正经的样子~嘿嘿
文文
实验杰青
耶稣受难像最后变成了XXY超人...这些人的思想太不可就要了 哈哈,Linyan造的小城堡还不错吧
虽说我一直觉得是口井...
这是谁的杰作?
生活更多是一种态度
April 01 当我们还年轻最近可能由于接触了一帆小朋友的缘故
于是常常在想自己已经变老的事情和事实
虽然小朋友在space自称老孙,却依然还是小朋友 ^ ^
前两天翻出来走之前给囊萤杂志写的那篇关于“人生起飞”的稿件
开头第一句话是
“我们最大的资本是年轻,有大量的时间可支配” 第二句话是
“做任何事情都有时间成本”
那个时候仍然还有着充足的牛犊精神,作为一个年轻之为学弟者,
蔑视一切年长于我之为学生及其他年长有成就者
自信凭己之努力,给定还有的时间,必然可以胜过一切那些所谓某某的某某
这种信心源于年轻,正如老毛所言,
“一张白纸,没有负担,正好写上最美的文字,好画上最美的图画”
大一结束了,自己成了学长
每每被学弟学妹们唤作学长,往往并无特别的想法
大二结束了,尚未更加体会到年老的学长的滋味,就来了这里
因为同辈人都在year 2和自己竟然还学了三门year 1的课的缘故,始终未有年老之感(潜意识里有装嫩之嫌,但既然为潜意识,自非自我意识所控)
大三快要结束了,遇到了Zhang Hu和一帆小朋友,
开始准备回去和毕业之后的事情也开始陆续受到些厦大的学弟学妹们询问来交流的事情
终于才开始极度地感受到身为学长而从更年轻一代人身上所获得的压力
他们的白纸上,尚未有任何负担,还有机会写上最美的文字
而我们的呢 于是在挑战前行者的同时,
又不断implicitly受到后来者的挑战
于是偶尔会想有一天自己老到动不了,是不是会依然没有任何成就
偶尔会考虑,自己把过去的年华,当作机会成本,终究是换回了什么
偶尔想想,原来年轻一代,毕竟还是比年长者厉害
当然考虑这些并非仅仅在空叹时光如梭,岁月蹉跎
对自己更多是一种激励
看了很多小朋友的文字
却未曾留言
因为未敢以己之已然经历时间浸染之言,
玷污一尘不染之莲
出淤泥而不染,
濯清涟而不妖
才是人之至高境界一种
而我已然已无法做到
也已然有了从现实的理想主义者
向现实的现实主义者转变的迹象
我先前所蔑视的一切
似乎竟毫不留情的开始发生在自己身上
所幸,虽然未比年轻者年轻,
却尚未比年长者年长
写到上一句突然想到韩愈《祭十二郎文》结尾的感叹
呜呼哀哉!尚飨
想到原来这篇文章的目的,
竟终究在于祭奠已经逝去的年华
然而讽刺之至,这又是某种成长的代价
做一切事情都要冠上种种堂而皇之的理由
以致最终忘了最初作事情的本意
我又开始有些蔑视现在的自己了
这正是改变的开始
