地震的震级比当年唐山公布的7.6级还高,并且地震深度只有10km,这个数据意味着地震很巨大。并且伴随现在的雨水,次生灾害滑坡泥石流也会带来更大的伤害,特别是在救灾部队无法抵达的情况下,受灾情况会成倍加剧。

How to write a research proposal

Thursday, March 6th, 2008

写研究计划是申请国外大学博士研究生的重要一环,因为很多大学在你申请的时候都需要你提交一个personal statement和一个research proposal,而对于国内的学生,很少触及这一块,所以在我申请的时候,查到有些有用的资料,特别是这个夏威夷大学的Proposal Writing的网站

我是由于其中一篇文章由Paul T. P. Wong(Trinity Western University, Langley, BC, Canada,ptpwong[at]shaw.ca)文章找到的,这个文章我看过中文版本,英文其实很简单宜懂宜用,但是上面那个链接却无法打开这篇文章,所以将其全文转到后面,希望有用:

A research proposal is intended to convince others that you have a worthwhile research project and that you have the competence and the work-plan to complete it. Generally, a research proposal should contain all the key elements involved in the research process and include sufficient information for the readers to evaluate the proposed study.

Regardless of your research area and the methodology you choose, all research proposals must address the following questions: What you plan to accomplish, why you want to do it and how you are going to do it.

The proposal should have sufficient information to convince your readers that you have an important research idea, that you have a good grasp of the relevant literature and the major issues, and that your methodology is sound.

The quality of your research proposal depends not only on the quality of your proposed project, but also on the quality of your proposal writing. A good research project may run the risk of rejection simply because the proposal is poorly written. Therefore, it pays if your writing is coherent, clear and compelling.

This paper focuses on proposal writing rather than on the development of research ideas.

Title:
It should be concise and descriptive. For example, the phrase, “An investigation of . . .” could be omitted. Often titles are stated in terms of a functional relationship, because such titles clearly indicate the independent and dependent variables. However, if possible, think of an informative but catchy title. An effective title not only pricks the reader’s interest, but also predisposes him/her favourably towards the proposal.

Introduction:
The main purpose of the introduction is to provide the necessary background or context for your research problem. How to frame the research problem is perhaps the biggest problem in proposal writing.

If the research problem is framed in the context of a general, rambling literature review, then the research question may appear trivial and uninteresting. However, if the same question is placed in the context of a very focused and current research area, its significance will become evident.

Unfortunately, there are no hard and fast rules on how to frame your research question just as there is no prescription on how to write an interesting and informative opening paragraph. A lot depends on your creativity, your ability to think clearly and the depth of your understanding of problem areas.

However, try to place your research question in the context of either a current “hot” area, or an older area that remains viable. Secondly, you need to provide a brief but appropriate historical backdrop. Thirdly, provide the contemporary context in which your proposed research question occupies the central stage. Finally, identify “key players” and refer to the most relevant and representative publications. In short, try to paint your research question in broad brushes and at the same time bring out its significance.

The introduction typically begins with a general statement of the problem area, with a focus on a specific research problem, to be followed by the rational or justification for the proposed study. The introduction generally covers the following elements:
1. State the research problem, which is often referred to as the purpose of the study.
2. Provide the context and set the stage for your research question in such a way as to show its necessity and importance.
3. Present the rationale of your proposed study and clearly indicate why it is worth doing.
4. Briefly describe the major issues and sub-problems to be addressed by your research.
5. Identify the key independent and dependent variables of your experiment. Alternatively, specify the phenomenon you want to study.
6. State your hypothesis or theory, if any.
7. Set the delimitation or boundaries of your proposed research in order to provide a clear focus.
8. Provide definitions of key concepts. (This is optional.)

Literature Review:
Sometimes the literature review is incorporated into the introduction section. However, most professors prefer a separate section, which allows a more thorough review of the literature.
The literature review serves several important functions:
1. Ensures that you are not “reinventing the wheel”.
2. Gives credits to those who have laid the groundwork for your research.
3. Demonstrates your knowledge of the research problem.
4. Demonstrates your understanding of the theoretical and research issues related to your research question.
5. Shows your ability to critically evaluate relevant literature information.
6. Indicates your ability to integrate and synthesize the existing literature.
7. Provides new theoretical insights or develops a new model as the conceptual framework for your research.
8. Convinces your reader that your proposed research will make a significant and substantial contribution to the literature (i.e., resolving an important theoretical issue or filling a major gap in the literature).

Most students’ literature reviews suffer from the following problems:
• Lacking organization and structure
• Lacking focus, unity and coherence
• Being repetitive and verbose
• Failing to cite influential papers
• Failing to keep up with recent developments
• Failing to critically evaluate cited papers
• Citing irrelevant or trivial references
• Depending too much on secondary sources

Your scholarship and research competence will be questioned if any of the above applies to your proposal.

金陵地理年会报告日

Monday, November 5th, 2007

报告是在南师大的仙林校区,满满的报告名单上面很多人都没有来,要做报告的很多是项目的成果,功利性质比较高,也有很好玩的,我就是到处飘找好的报告,偷到ppt;要不就是南大、南师大的研究生,毕竟只是窥豹一斑,很难给出高的评价,以后再写体会吧。放些照片(真的转型成贴图博客了)。

上午T65准时达到南京,豪华的火车站,看起来有国外火车站的感觉,照片回去的时候补上。出了车站就是巨大的玄武湖,阳光明媚虽然云层很厚。

到了住处金陵之星,注册,押金,找房,订票,一通折腾之后终于在11点入住811。房间很不错,ms原价要580,竟然还有电脑和网络,还有pay-moive….

中午的自助餐,就是和龙小姐吃饭,看来未来几天都这样,明天的会议看起来大牌们的发言还是挺好玩的,后天就该自己了。

Wordcamp2007, Beijing

Sunday, September 2nd, 2007

在系统构架师tsing的怂恿下去北航参加了wordcamp2007, Beijing(一个wordpress用户的聚会)。据说是模仿wordcamp2007, San Francisco CA。虽然各位主教人物的发言,以及各位大牌Blogger都不是我关注的范围(太泛的主题明显tsing同学也不感冒,不过在询问谁开发过wordpress插件时低调地炫耀的举起手),但是还是抢到两件衣服,博邻的衣服看起来怪怪的像工人装,Wordcamp的衣服(蓝色)是中号,穿起来像蜘蛛侠。

不过很高兴碰到很多传说中的人物,比如su27庄秀丽老师(他儿子和我玩积木的时候我只能说我还是输给21世纪的小朋友)。BTW,北航的餐具和选菜过程比北师爽,地盘大就是有好处。半途接到老板急电,下午的车东居然就错过了,不过现在贴图(我和神仙的照片乃su27用Nikon D50拍的,好生羡慕)。

Farewell, Harbin

Saturday, August 25th, 2007

昨天晚上是告别的晚宴,大家终于在同心吃了一顿自助餐,那么多foreigner,还是很好玩的。可惜没有带相机下来,Terry,Kos,Katharina,Whiteford……都没有合照,后面要去中央大街看夜景,顺道和哈工大的志愿者们合照了一张,虽然我只知道其中金书淼和郭佳的名字,不过还是要感谢你们大家。

和哈工大志愿者的合照

夜晚的松花江畔,有鞭炮,有歌声,有轮滑,甚至还有孔明灯,路边都是画像的,吃了著名的马迭儿冰淇淋。但是9点之后,中央大街就开始人烟稀少了,高挑的MM也甚少见到(哈尔滨逛街的男生比女生多)。

之后杀往果戈里大街,真的是大街,很长的说。有酒吧聚集处,有迪吧聚集处,还有少见的有轨电车。站在河畔,听着还不赖的KTV声音,河水倒映着灯影,远处还有烟火,加上阵阵凉爽的风,这幅景象还是很浪漫的。
