Plain but Colorful: A Summary of 2009

image No one can deny the process of time processing, for which, the individuals like us, can only obey this regulation. Time pass smoothly no matter whether you are successful or not, no matter whether you are taking adequate care on it, and no matter whether you are young or old, boy or girl. Following my traditions, I would like to take a summary of my past year at last day. Taking a scan on the summary of mine in 2008 and 2007, I find, my 2009 is quite plain,there is nothing impressive to note, and honor to share with, except for something unpleasant.

The GRE, both the preparation and the two attempts,forms up the the mainstream of my life this year. Admittedly, GRE is the most difficult exams for the students in China because of two reasons. The first reason is that you are required to memorize and understand over 20k words. My first failure in this step is that I failed to make an in-depth understanding of the words, but only try to memorize them.  But the problem is that without good understanding on the real meaning, you can hardly find the potential relationship between the words and hence you fail. Anyway, my writing skills is greatly improved during this preparing process. I can start to write my own formal English. Admittedly, without sufficient training on GRE training, I won’t finish my first English manuscript and the research proposal.

For academia, there is nothing important as well except for the training program in Shanghai, conducted by the Chinese University of Hong Kong. Due to the funding from my professor and the arrangements on my research, I didn’t go to any highly ranked academic conference, totally different from what I did in 2008. However, I have to say, not to flatter the faculties of CUHK, their lectures broaden my horizon on my research greatly. From their delivery, I learned the importance of fundamental papers, always those enlightening works that also own great amount of reference. Without sufficient understand on the previous literature, not only for my topic, but also the common backgrounds, I won’t be a qualified scholar and a qualified reader of the papers in top journals.

Though I get the scholarship, and the prize of honored paper from an internal conference, I am not satisfied. For the scholarship, I have experienced too much, much more than it deserved. Though the prize of the honored paper partially convinced myself of the potentials of research, that’s far from enough. I would not repeat all these trivialities. For those readers who are interested in further information, please refer to relevant posts.

The perspective of my 2010 is quite simple, just two English words-Go Smoothly!

At the end of my summary, I shall acknowledge the thanks to numerous people that have helped me in various realms. Some of these friends are Kuan Song, Prof. Wang Xiongyuan, Prof. Xu JIalin, Prof. Shirley J. Daniel, Zhang Peng, You Tingting, Guan Kaolei, Tang Jianxia, Zhuang Chunfang, Chen Wenna.  Fundamentally,I shall express my thanks heartedly to my mama, papa, and the gone grandma. I wish and would keep appreciating your kindness in the coming 2010.

Do Real Work, Think Over Real Questions

image The application to the PhD Program may be regarded as the greatest failure on my individual plan for my future in the past years. While frankly, such efforts, though bring me no benefit on its proposed directions, show my a good lesson. That is, do what you can do, but never make attempts on those you are not familiar with. Doing something particular in a unsuitable environment, where you can hardly find reference, would directly bring you to the failure. Positioning is too essential for a reasonable decision-maker, without reasonable positioning, things can go terrible.

I was supposing the prize from the conference held at my birthday can bring me more courage, recovering myself back to the old days when I am fully prepared and encouraged to both the challenges and academic research. However, I found it didn’t work, I still remained what I was, no significant change at all.  My confidence on previous research, the pursuing of a PhD program overseas has been totally abandoned. Well, I am so lucky that I registered for the PhD admission exams of Sun Yat-sen University, where can bring me acceptable reward, if I am successfully admitted.

A first reason may be from the research itself, as I hereby conclude, after a deep consideration. Comparing to the majority of postgraduate students in China, I am a lucky dog. I have a good supervisor, helping me building up solid foundation on my research. However, for the empirical research, a contemporary research methodology adapted in China since 1992, we are both rookies. We select our topics from existing literature. That is right and reasonable, why? We are professor and student respectively, neither owns sufficient practical experience. To tell it frankly, we don’t have the first touch of the real world. What’s the consequence then? We don’t have our own story. How will it be then? We get topics from papers, not from the real world. My emotion on research may thus be greatly mitigated when such problem is aware of, but without any good solution.

The other reason may directly come from the selection of graduate school. Undoubtedly, it is a hard decision.  Given a high certainty on going overseas, I shall not have to fight for the top schools in China. It is a time-consuming and tiring job, without any pleasure at all. However, considering the limited reputation of our school outside China, and the limit on number of candidates going overseas for PhD, there is no reference. That is, I can hardly evaluate my own probability of admission to international graduate school. Under such situation, giving up top schools in China can be too risky. That’s why I finally made such decision. While,such decision can hardly mean peace, it reflects much more the selection itself.

I am writing this post for two aims, one is to express my depression, which has been done in previous paragraph. The other one is to identify my understanding on ethics of research. Do real work and think them over should be a key determinant to the future research. The interest of research can only come when you are doing a real question. In fact, I was firstly supposed to write a proposal on privatization of state-owned firms in China. After an attempt for 15 days, I gave that up. This abandon directly wastes my time of 15 days, but I get this lesson. And I am now starting to aware of why many scholars overseas are so interested in research. They are doing real research grounded on real world!

This is an article sharing my own feeling and understand on research. Your comments are welcome.

A Special Birthday: Academia and Entertainment

Christmas Birthday Stickers from Zazzle.co https://blog.gujun-sky.com估计傻瓜都知道工作是工作,娱乐是娱乐,两者不可混为一谈。否则会一事无成。但是呢,在今年的圣诞节,也就是本人的生日之日,这两者却似乎找到了一个不错的交点。在这美妙的一天里,我同时完成了学术任务和娱乐任务。可谓工作与生活兼顾。不过说实话,我也累得够呛。这个故事还得从三天前的一个电话说起。那天晚上,哥们正在忙着拜读新买的《四书集注》,正在为《大学》开篇中的“齐家治国天下平”而激动不已,心情澎湃,却忽然接到研究生部的通知说要参加今天的第二届会计学院研究生学术研究研讨会,并作大会报告。一开始也没有觉得什么,毕竟咱也是久经沙场的人嘛。但是师弟的下半句却让我心慌了很久。因为他告诉我,我的报告被夹在了两位学术牛人之间,更何况,其中有一位还是在下的恩师。这下好了,关公面前耍大刀了。但是呢,我们是社会主义一块砖啊,哪里需要放哪里。于是,在下只有恭敬不如从命。

所谓喝水都能噎死人,阴沟里照样翻船理论,同时援引本人的一贯遭遇,此次演讲注定不会那么顺利。事实再一次验证了统计学的重要性。先不说我只有两天时间来准备PPT和讲稿,光演讲时候的PPT自动往前跑就让我非常郁闷,以至于我今天毫无演讲的性质和激情。脑子里的那些理论,假设都被抛开了。更多的,我一边在讲,一般在小心防备着我的PPT自动往前走(刚测试发现,这可能是03和07的不兼容性的一个Bug,出现于某些特定情况)。同时,这个报告也说明了一个问题,永远不要用中文去报告自己用英文写的论文。那过程绝对是自虐。今天我不得不一边看着PPT,一边把脑子里的英文换成中文再说出来。于是开始了舌头打结,语无伦次。好在,这不是太高级的会议。不过我那敬爱的老板的表情还是让我着实来了一身冷汗。哎,太年轻啊,定力不行。

下午跟着同门好友跑到西苑唱歌去了。你别说,KTV还真是个发泄的好东西。尽管这种事情多少有点损人利己。在给被人带来了极其恐怖的噪音之后,自身的感觉会变得非常轻松。同时,我也跑回去领了个奖。在唐院长最后宣布我名字的时候,那感觉还是非常爽的。上台领奖时候还是很兴奋的。难怪那些影星影帝会在颁奖典礼上语无伦次的感谢什么CCTV,MTV之类的。哎,看来如此感谢,如此言语也都是非条件反射啊。

晚上在南苑吃的,建霞弄来了一个漂亮的蛋糕。如果说蛋糕本身没什么,关键在于情意之类的话,那恐怕有点假。毕竟我还是个好吃的主儿。不过跟同门的师兄师妹们一起过生日的感觉真是不错的,温馨而充实。加上我的4+1(此为张院长原创,4为四位学术牛人,1为在下),我真是在生日这一天找到了学术和娱乐的完美结合点。但是,我绝对不认为这是个帕贝托改进,因为,我实在是太累了。

其实坦言,学术研究的确是需要激励的。我很羡慕学术班的人有如此好的条件。但是呢,也为大多数人的身在福中不知福而感到可惜。当然,人各有志,学术也不是唯一出路。正如我以前所言,在这里,我们选择的学术道路可能是曲折的,甚至是郁闷的,在这样的环境下能够坚持下来是要点道行的。所幸,本人遇到了很好的老板,也得到了比较多的激励。在这些激励下,我现在的成果其实还是比较悲惨的。之所以要感谢老板,原因很简单。有句老话“师父领进门,修行在个人”。但是问题是,如果没有师父领进门,您老难道还打算在门外修行不成?当然,释迦摩尼在菩提树下得道。可是,我们皆凡人。

原本以为今年一年都不会有学术会议上的记录,没想到今天却填上了这一空白。尽管这会级别不高,收益却不低啊。

Long-term Decision V.S.Shrt-seeing actions: from a TV Show

最近因为事情太多,总是变得无比烦闷和暴躁。似乎一瞬间,自己什么都不是了,自己什么都不会做了。过去的两年的研究生也白读了,以前做的研究现在看来也是错误百出,非常幼稚。然而,看了今天听听给我推荐的《一代大商孟洛川》。我突然似乎了解到了一些东西。该剧情节跌宕起伏,很有励志的效果。但是,与《大宅门》,《乔家大院》等类似题材的电视剧相比,我个人认为,此剧最出彩的地方,恰恰就是在本剧一开始主人公的恩师的一番教诲。

这番教诲初次听来似乎有些老调重弹,尽管我们无法准确回忆这些语句究竟出自于哪里。但是,让我越来越信服的是,当你有了一些相关的阅历以后,你才能更好地去理解经典。其实在很多时候,我们就是那些在学术场傻上追逐三分利的小商小贩,却不会真正的去全局的、发展的眼光去看问题。此类说法似乎永久性被我们定格在了思想道德课本或者政治课本上。不得不说,这是一种很可悲的失败。举一个学术上的例子就可以说明。会计学和财务学界的论文似乎永远都在微观层面上转悠。我们讨论的话题永远就是公司是否盈利,股票是否可以顺利买卖,似乎没有人考虑过个别公司的逐利是否会对征稿个社会的福利造成影响。而传统的经济学研究中,福利分析是很重要的。很难想象一票经济学研究不去考虑福利问题。用一个不恰当的比喻,我们是在像销商人一样在做研究,却没有大商人的研究和气魄。或许,这是我们需要注意的吧。

而另一项让我感慨的则是关于“给予”的探讨。其实这是上一段讨论的一个范例。之所以单列出来,是因为我觉得这个更直接理解,而且也是更有用的。而能否做到“给予”则是一门非常大的学问。更多的,这个问题可以推广到很多社会问题。比如我们的拆迁问题。我们的政府什么时候会真正像大国一样为民牟利呢?其实这就是一种给予问题。当政府给予了拆迁户一些恩惠时候,拆迁办就会更得人心从而提高效率;在大学里,行政人员和教授的关系总是不好。这似乎成了一条国内通用潜规则。究其原因,也是出在了“给予”上。同样,公交车让座问题等都可以纳入。这让我想到了一句数学家的名言,最简单的方程式有时候是最不好解释的。

最后要提到的一句话,则是来自主人公的母亲——“今天失败到了这个地步,你只有两个选择。要么就从这里给我滚下去,要么就像一个男人一样站起来。”。事实上,我们现在总是面对各种压力,升学,工作,人际关系,信任危机,甚至于我们最不愿意被提起的潜规则。但是这些问题是我们能改变的么?不是的,我们只能去适应。所以,我们不要杞人忧天,我们要尽可呢想清楚我们可以预见的。后悔是数学没学好的典型表现。试想,一个连先验概率和后验概率都不俄区分的人,显然不会学好贝叶斯模型,更不可能学好数学了。

最后用一句话结束我的博文:君子坦荡荡!

LYX: A New Written Instrument

经过几天的奋斗,终于完成了研究计划的初稿。12页的英文写作果然不是闹着玩的。累的我差点小命送掉。不过这次我也得到了一个教训,那就是,只有自己熟悉的东西才能做好,永远不要轻易去尝试你所不了解的事情。不过首当其冲要感谢的,则是我在Linux下新伙伴,LYX。这个系统同时给了我LATEX系统的便捷,也让我享受到了可视化编辑的乐趣。我之所以喜欢LATEX,是因为在我结束了最后一个字符的同时,我的文本排版也在倾刻间完成了。这是Word系统远远不能比拟的。

我不知道现在新版本的LYX是否支持了JabRef的管道功能。至少在我于Windows系统上使用LYX 1.5的时候,该项功能是不支持的。在LYX中输入参考文献的唯一方法是直接在系统自带的BiBTEX中跟据Key来寻找。这是一个非常费力而且容易出错的工作。尤其是对于我这样的习惯Endnote的人而言,不能从文献管理工具直接插入Citation,而是需要如此的手工操作直接就是一场噩梦。另外,如Bill所言,Java在Linux下的执行效率相当高,这也为我电脑上流畅运行JabRef提供了保证。

说到JabRef,我不得不同时提到另一个工具。该工具是Firefox下的插件,叫做Zotero。这个插件可以非常高效从Google Scholar,JSTOR等数据库中快速提取Reference,并且记录。此类技术,比较Endnote的导入工作,显得更进了一步。当然,不可否认,Endnote可以使用大部分英文数据库的Direct Export。这也是非常有吸引力的。

最后要提到的Bibtex的自动生成Reference。不知道为什么,我总觉得BiBtex显示的效果要比Endnote要漂亮。Lyx还有一个很人性化的功能。就是你在插入Citation的同时,可以选择显示方法,比如王小二(2009)要改成(王小二,2009)。这点比Endnote需要手工修改来的容易的多。

总而言之,我觉得Ubuntu+Lyx+Zotero是一个不错的选择,绝对不亚于Windows+Word+Endnote。有兴趣的朋友可以去试试看哦。

Linux: My New Working System

对于大多数会计专业的学生而言,Linux应该是一个陌生的名词。事实上,这是一个基于UNIX构架的个人版系统。它的计算性能非常优秀。著名的Matlab,Mathematica等工具在Linux环境下都有着远胜于Windows平台的表现。而科研写作工具Latex的配置也比windows下高效和便捷的多。只是由于我们的研究很少使用这类“高级”工具,而且中文论文也必须使用Word文档来投稿,这个好东西自然就入不了大多数人的法眼了。

其实我知道Linux差不多已经有十多年了,第一次使用发行版是在迅达的家中。当时我们对Linux都有着一种神奇的向往,而他当时也有个人电脑可以用来尝鲜。记得当时市场上有卖Redhat的套装,78元,一个大盒子,10张光盘。只是当时作为高中生的我们,78元的价格还是略显太贵,最后他选择了Fedoral,版本号记不得了。当时第一次看到这个系统的感觉就是新奇,但是我却死活想不出来这个系统可以用来干吗。更多的,在当时56K 的时代,网络下载软件还是一种奢侈行为的年代,使用Linux是属于典型“折腾”行为。毕竟我们没有使用它来替代Windows的足够好的理由。

在我有了个人电脑的时候,Linux的世界已经发生了翻天覆地的变化。Redhat似乎已经不再做桌面系统,而是直接将其交给了社区来管理,fedoral倒是依然健在,不过似乎也是社区发行版,网上有了足够多的Linux社区,讨论版和个人博客。市场上似乎也很少看到盒装发行版。更多的Linux则是直接从网络上下载。Linux下的软件也丰富了很多。更方便的是,使用Linux几乎不会遇到版权方面的问题,毕竟这个平台下的大多数软件都是开源的。(当然,使用Matlab的话,我目前还只能继续盗版,毕竟正版价格对我来说还是个天文数字。期间我第一次接触了Ubuntu,当时是7.04,直到今天我还记得其中有一段曼德拉的关于世界和平的讲话。

这次使用Ubuntu 9.10,则是我第一次真正的把系统用于工作环境。因为在此系统下使用和安装Lyx(一个Latex的前端,免除了写大量代码的麻烦)都很方便,系统会根据其依赖(Dependence )自动安装所需要的package,这点比Windows 要方便了很多。当然,出于偷懒,我只是使用了系统自带的channel来安装了软件,却没有去从外部源安装。事实上,使用lyx写作省去了我大量的排版工作,只是,我现在还不知道怎么去使用中文,我尝试了xetex,却似乎有错误。xecjk无法正确加载。好在我目前写的几乎都是英文。

至于即时通讯,Pidgin作了个很好的典范,ibus提供的输入法尽管没有网络更新,但是却也很好用。一点儿也不逊于Windows下的Google 拼音。总而言之,这是个非常适合研究人员来用的平台。

PS :我现在使用的是BLOGTK 来写作的,但是这个编辑器不支持直接离线插入图片,搞得有点像当年学Cdida时候的HTML编辑器。有什么好的编辑器推荐下阿。

Goodbye! North America and My American Dream!

image Quite a long time I denied all the requests from my heart of writing a post in English, the reason can be quite simple. The failure on GRE directly abandoned me the American dream; what’s more, it deeply hurts my passion to my future life in years. In the past days, weeks and months, again and again, I have tried to imagine my life, a big house, a tenured position. But now, everything is gone. And, my purpose of learning this language has become invalid as well. Even till now, I don’t think the English can be useful for my graduate study in China, since most PhD candidates in the major of accounting are without good competence of foreign language, and such faults are also retained by most professors as well. in contrary, such competence may cause envy from colleague sometimes.

I can hardly remember when I devote myself to the study of this language. I admit that I never met the top level, since I never entered a top primary school, middle school, college, and the graduate school. But undoubtedly the American dream works. During the high school, I started to read some English newspapers, listening to the VOA News, and to chat with my English teachers and friends in English. Obviously such activities help me build a solid foundation, which is still beneficial today. (Just imagine how many students are still fighting for oral and listening sections).

The failure of the college entrance directly abandoned my improvement of English. The teachers for students of the technical school are that poor, that the memory of the English courses at that time is only the tricks, like the faults of the pronunciation, verbal and grammars from the teacher. And CET-4 and 6 are passed respectively, though the scores were not very high, but identical to my competence. Frankly, there is little improvement on my English during the four year study in college.

A great improvement of English competence comes to me when I entered the graduate school. For the research purpose, I have to read many papers from top journals written English. Obviously, good competence on reading formed since high school brings me great benefit. Even till today, I am still quite pride that very few graduate students around can take a faster speed than my reading. (A younger student used to acknowledge her greater amount of reading, while after some talking;  it is found she only read the abstract and conclusion).  And what’s more, the failure of GRE can not only mean failure, in fact, I learned how to write in a formal way. Without such training, I don’t think I can write an English paper and present in Hawaii.

Anyway, the GRE is failed, and my American dream is breaking down. With the concern of my willing to be a research, professor or so, PhD is an optimized choice still, since its honored acceptance here in China.  I will fight for some top universities in China, no other school will be considered since its limitation on marketplace. I don’t want to be a loser when graduated in three or four years.

Thanks for my brother; it is your help and encouragement that bring me confidence and broadened horizon;

Thanks for my parents; it is your help and support on my feeding up that I have the opportunity to make these attempts, though they are not successful;

Thanks for my uncle and aunt; it is your kind suggestion that prevent me from making wrong decisions;

Thanks for my uncle Yang yang, to be specific; you give me too much, courage, confidence, horizon and the meaning of a human being;

And thanks for Mr. Zhou and Ms. Luo; it is your encouragement during my early stages that I can obtain all these capabilities;

As a final, thanks for Peng and my present professor, though we have only a connection for less than three years, your determination and encouragement help I learn to be a rookie researcher. I am convinced what you taught me can be beneficial when doing independent research in future.

Reading the Blogs: The Way You Understand Him

image 今天终于开始着手准备国内的博士考试,尽管两次GRE的悲剧很是让我伤心,一度让我都没有了自信并在博客上发了大量的牢骚(如某某某某),以至于我对所有的“绣球”都来者不拒。非常感谢我姐在关键时候对我的激励,使我顿然醒悟,其实我并不是我想的那么没用,或许我也需要做些事情来证明自己。但是这种转变很容易因为年轻而变得锋芒毕露。锋芒毕露最要命的问题就是会让人很不爽,高调做事,低调做人或许就是这个意思吧。一些本来没打算伤害别人的事情却会因不太恰当的做法而出问题。如果再加上信息不对称,信息成本过高等问题的话,这个现象会更严重。

晚上看书看累了,在Google上闲逛(我一直有这种习惯),利用某一个关键字,居然很轻松的找到了我的一位至交好友的博客。这点事实上是让我非常吃惊的。因为他在我眼里似乎并不是一个非常喜欢接受新技术的人。我仔仔细细看完了这个非常素雅的博客的所有的日志。说实话,我心里起了非常大的波澜。因为这个博客帮我降低了非常大的信息成本,而同时也给了我一个Access进入了我这位朋友我所不知道的另一面。他那种内心的细腻,男人的坦荡,以及我们做研究的人所需要的那种心思缜密,都在那字里行间彰显无遗。相比较我们学校另一位教授的博客而言,我朋友的博客尽管没有那样工整的排版,却显然更具有可读性。因为,它们更能打动人。作为一名博客读者,我所关注的永远是原创和内容,而不仅仅是排版。

阅读博客,同读文章一样,也是分类的。我见过的博客往往包括了三类人。第一类的博客是我一般都不去的,它们往往是我们所谓的垃圾博客,里面的文章毫无原创性可言,都是一些网上摘录的东西,不多说;第二类,是博客的大多数,就是新浪,搜狐等等的托管博客(不包括熟人的)。托管博客往往都是偏文科工作性质,并没有技术或者动力去自己捣鼓一个博客的人。当然,第一类所谈的垃圾博客不包括在内。这类博客往往会有很多不错的文章,比如一些时尚热点的评论,以及一些名人博客。但是这类博客有被微博给侵占的危险。因为毕竟并不是所有人都喜欢在电脑前码一大堆字的。而最后一类,则是我基本每天都要报到的博客,基本属于我朋友们的博客。因为这样可以每天知道我的朋友们在关注什么,在做什么,在想什么。事实上,这本身也寄托着我本人对朋友们的一种思念。

至于博客的写作,则也有很大的讲究。比如我前面所提的那位朋友,他的博客更多显示了个人的内心世界和兴趣。这种博客是最符合博客的初衷的。第二类则是技术博客,比如我朋友Bill,他是个技术狂人,经常在博客上讨论一些技术问题,而这些帖子对我而言基本是可以跳过的,但每次看到技术贴,我都会知道,他一直在努力(哪家的广告词?),至于第三类,则是一些广告博客,比如Wordpress的官方博客,Google Analytics的官方博客等等。而至于我自己的Junjun’s Home?呵呵,我自己都说不清楚,尽管我倾向于第一类,但是有时候也讨论一些“不入流的”IT题目。

该睡觉了,就写这么多了,祝我那位朋友每天好心情。至于地址嘛,我还是不公开了吧。

对了,有玩博客朋友可以考虑Follow我哦
