Introduction

All kinds of research, researcher must have a strong understanding of preceeding research on the same or similar subject. Master and PhD student, as a kind of researcher, must compose a literature review before they hold permit to start their research. Usually we use the term literature review as a form of formal written document that summarises all previous related researches.

The general steps are:

  • searching articles with certain criteria.
  • published article on reputable journals.
  • presented abstract on reputable conferences.
  • extract the results from each article, what data is used in it, and how the author analyse it.
  • summarise and compile the result to mark a baseline for your research.

However if we dig deeper, we can find that there are at least two kinds of literature review:

  • Annotated bibliography: What is an annotated bibliography? These are several good definitions on the term:

An annotated bibliography provides a brief account of the available research on a given topic. It is a list of research sources that includes concise descriptions and evaluations of each source.UNSW

Another definition even gives an average sum of words:

An annotated bibliography is a list of citations to books, articles, and documents. Each citation is followed by a brief (usually about 150 words) descriptive and evaluative paragraph, the annotation. The purpose of the annotation is to inform the reader of the relevance, accuracy, and quality of the sources cited. Cornell Univ.

  • Systematic review: [I will add this later on]

Hands on

Now we get to the real part, searching for references. There are so many ways to get related readings and references. The old-fashioned way is to go to your university library. Tempting huh ūüôā I would suggest this as the best way. Not only you will get the one document that you have been looking for, but also you will feel the atmosphere in there. Although there are more online documents nowadays, but still I would sit still nlibrary (if I have time). You might by any chance get the oldest record on whatever you are looking for. Then there is always be internet as the backbone of researcher around the globe. The problem is, where to find it.

  • Search Engine: Google, the most obvious man???s best friend. Off course there are others, like: Bing, Microsoft Academic and our old mate Yahoo. You might want to visit list of search engine. But be careful with using Google, because it crawls on any documents that matched with our keyword. So it could be a real scientific paper on a scientific journal, or a newsletter or simply an email in a miling list. But starting from November 2004, Google has make improvement on the matter by launching Google Scholar. Now you can get more refined result with this tools. Five years later, in December 2009, Microsoft launched Microsoft Academic. Citation database or scientific database: we???re already familiar with Scopus, Science direct, Proquest, or Web of Science. You can start with both links, since different company would likely have different database and searching algorithm. If you are working or affiliating to a university that has subscription to any of the database, then you have eliminated half of your problem :-).

  • Or your university has a cross-referencing system that access multiple databases in the internet. You are the lucky one :-). Just type in the keyword in it then you get more results from multiple resources. I???ll continue later on with my own case of reference searching.

Microsoft Academics

Following my previous post on simple bibliometric with GS Google Scholar, this time I try to do the same steps with MSA Microsoft Academic. The pros in using MSA is that it offers categorization of scientific entries. This is not available with GS. In this post I tabulated and compared each category with several keywords. Here I used the following keywords:

  1. West Java
  2. Bandung
  3. Citarum
  4. Cikapundung
  5. Groundwater Bandung
  6. Groundwater Citarum
  7. Groundwater Cikapundung
  8. Health Bandung

The following list contains the categories that automatically built by MSA:

  1. Agriculture Science (agsci)
  2. Arts & Humanities (arthum)
  3. Biology (bio)
  4. Chemistry (chem)
  5. Computer Science (comsci)
  6. Economics & Business (ecobus)
  7. Engineering (eng)
  8. Environmental Sciences (envsci)
  9. Geosciences (geosci)
  10. Mathematics (math)
  11. Material Science (matsci)
  12. Medicine (med)
  13. Multidisciplinary (muldis)
  14. Physics (phy)
  15. Social Science (socsci)

I worked around this with the following codes.

# load library
library("lattice")
library("gridExtra")

I use LibreOffice to prepare the data. Basically every keyword consists of 15 observations (see the result from head(bib)).

# load data
bib = read.csv("20140523b-summary references.csv", header = T)
head(bib)
##   no               fields2 fields     key dbase sum
## 1  1  Agriculture Science   agsci Bandung msacd  16
## 2  2    Arts & Humanities  arthum Bandung msacd  44
## 3  3              Biology     bio Bandung msacd 129
## 4  4            Chemistry    chem Bandung msacd 153
## 5  5     Computer Science  comsci Bandung msacd 406
## 6  6 Economics & Business  ecobus Bandung msacd  44

I did the subsetting for each keyword.

# subsetting data
bib.wj = subset(bib, bib$key == "West Java")
bib.bdg = subset(bib, bib$key == "Bandung")
bib.ctr = subset(bib, bib$key == "Citarum")
bib.ckp = subset(bib, bib$key == "Cikapundung")
bib.gwbdg = subset(bib, bib$key == "Groundwater Bandung")
bib.gwctr = subset(bib, bib$key == "Groundwater Citarum")
bib.gwckp = subset(bib, bib$key == "Groundwater Cikapundung")
bib.healthbdg = subset(bib, bib$key == "Health Bandung")

I used lattice and gridExtra package for plotting. You may use another package, but you have to change the codes.

# plotting
plot1 = xyplot(bib.wj$fields ~ bib.wj$sum, pch = 21, fill = "red", xlim = c(0,
    8000), main = "key: West Java")
plot2 = xyplot(bib.bdg$fields ~ bib.bdg$sum, pch = 21, fill = "red", xlim = c(0,
    8000), main = "key: Bandung")
plot3 = xyplot(bib.ctr$fields ~ bib.ctr$sum, pch = 21, fill = "red", xlim = c(0,
    8000), main = "key: Citarum")
grid.arrange(plot1, plot2, plot3, ncol = 3)

plot1


plot4 = xyplot(bib.gwbdg$fields ~ bib.gwbdg$sum, pch = 21, fill = "red", xlim = c(0,
    50), main = "key: Groundwater Bandung")
plot5 = xyplot(bib.gwctr$fields ~ bib.gwctr$sum, pch = 21, fill = "red", xlim = c(0,
    50), main = "key: Groundwater Citarum")
plot6 = xyplot(bib.healthbdg$fields ~ bib.healthbdg$sum, pch = 21, fill = "red",
    xlim = c(0, 50), main = "key: Health Bandung")
grid.arrange(plot4, plot5, plot6, ncol = 3)

plot2


plot7 = xyplot(bib.ckp$fields ~ bib.ckp$sum, pch = 21, fill = "red", xlim = c(0,
    10), main = "key: Cikapundung")
plot8 = xyplot(bib.gwckp$fields ~ bib.gwckp$sum, pch = 21, fill = "red", xlim = c(0,
    10), main = "key: Groundwater Cikapundung")
grid.arrange(plot7, plot8, ncol = 3)

Learning R: Using Sweave on OS X 10.6 and fix the Sweave.sty problem

This blog shows a very clear tutorial on how connecting R-sweave to your Latex system. R-sweave (you can see it in the “New” button >> “R Sweave”) is a facility in R environment to generate neat report based on your R code. This function allows us to make a document report of your R codes, on Latex format. The fun thing is R-sweave will run your codes then put it in your Latex doc report automatically.

For you that are “still” using MS Word, you’ll have to copy-paste your R codes to the Word doc back and forth (but there’s “Pandoc” or “Pander” package that do the converting for you.

Thanks to Friedrich Leisch for sharing the tutorial.

LaTeX for absolute beginners

This is a useful post about learning Latex editor. I’ve been using it for a year now, but my learning curve was nearly flat about this because I kept moving back and forth to LibreOffice (it was my way to colaborate doc texts and tables with my colleagues, which were still in “Microsoft State of Mind”. Now that I’ve done mainly solo works I can do a step up on my Latex learning curve. Currently I’m writing a paper for a journal using Tex Studio, so I will need all the help i can get, especially on citing and referencing using Jabref as Reference Manager and BibTex as citation format.

WTF: Book vs thesis

unknown book

[image from: diythemes.com]

This is how a book is defferent that a thesis (combined from various sources)

  • A book doesn’t actually need an original theory. It needs an original view point. So you can freely bring your own perspective.
  • A book has a broader (general) readers, so you have to provoke and engage them to read your book.
  • General book-readers are simply want to know what you’ve found out and what you think about it. Offcourse you need to include your references as a basis, but your readers will focus on what you’re saying.

So several sources recommend to do the following tasks:

  • remove all academic “scaffolding” and focus on your own opinion. Reduce scholarly aparatus.
  • reorganize to make it more interesting to read; refocus your story.
  • rewrite with more direct and personal voice: use first person story telling (I or We) and use active voice.
