Brain Drain of India - Some Statistics

Brain Drain of India - Some Statistics |Sulthan Academy

Today,I present some of the key statistics that draws attention and bring alarm bells to India. Among Asian countries, India continues its trend of top the list of immigrant scientists and engineers to the US, says the latest report, adding that with 950000 Indians out of Asia's total of 2.96 million, this report of 2013 represented an 85 percent increase from 2003. Overall, the number of immigrant scientists and engineers in the US has risen to 18 percent from an earlier 16 percent and 57 percent of those were born in Asia. From 2003 to 2013, the number of scientists and engineers residing in the US rose from 21.6 million to 29 million. This 10-year increase included significant growth in the number of immigrant scientists and engineers, from 3.4 million to 5.2 million, said the report from the National Science Foundation's National Centre for Science and Engineering Statistics (NCSES). In 2013, 63 percent of US immigrant scientists and engineers have naturalized citizens, while 22 percent were permanent residents and 15 percent were temporary visa holders. Also, the human capital is not only a major problem in India, It is also a key problem for many Asian other countries. Since 2003, the number of scientists and engineers from the Philippines increased 53 percent and the number from China, including Hong Kong and Macau, increased 34 percent, the report added. The NCSES report found that immigrant scientists and engineers were more likely to have earned post-baccalaureate degrees than their US-born counterparts. In 2013, 32 percent of immigrant scientists reported their highest degree was a master's (compared to 29 percent of US-born counterparts) and 9 percent reported it was a doctorate (compared to 4 percent of US-born counterparts).The most common fields of study for immigrant scientist and engineers in 2013 were engineering, computer and mathematical sciences and social and related sciences, the findings showed. Over 80 percent of immigrant scientists and engineers were employed in 2013, the same percentage as their US-born counterparts. Among the immigrants in the science and engineering workforce, the largest share (18 percent) worked in computer and mathematical sciences, while the second-largest share (eight per cent) worked in engineering. Three occupations - life scientist, computer, and mathematics scientist and social and related scientist saw substantial immigrant employment growth from 2003 to 2013, the report said.

Evince an alternative for Adobe reader on Linux for PDF readers

Evince an alternative for Adobe reader on Linux for PDF readers
Its been One and half month I have completely migrated from Windows to Linux distro. On my experience I face some compatibility issues and problems in finding substitute for software that I use in Linux. One such key problem is to find good reader like Adobe reader. I am researcher and I read more books in my laptop. 

Adobe reader is free for Windows , Mac and Android users and its mostly used among the PC, tablet and Mobile users. Un fortunately Adobe doesnt supports its pdf reader with Linux distros. The good thing is there is a better substitute for adobe reader . Ya I mean better substitute . It's Evince.

Evince is document viewer for multiple document formats. It supports the following file formats: PDF, Postscript, djvu, tiff, dvi, XPS, SyncTex support with gedit, comics books (cbr,cbz,cb7 and cbt). The question is will it work as good as an Adobe Reader for Windows. 

Evince is default document viewer on Gnome desktop and in Ubuntu distros. I tested myself the reader with one simple pdf document, a pdf with lot of graphics (a DK Publication's )and a signatures pdf file (aadhar card).

Both simple pdf and a pdf with lot of graphics opened and had a smooth flow of pages over the document. The pdf is light weight and doesn't slow down the other multitasking software side by side .Where as Adobe reader take a significant amount of RAM for smooth performance. 

As far as Signature pdf. I used my Aadhar card. The document opned with out any issues after receiving a prompt for password as Aadhar is password protected file. But there is a problem in verifying the signature. I found in Ubuntu support forum. Evince unfortunately doesn't support this feature to verify the documents signature yet as of Feb 2017. Developers are working on it and hope you will get the support soon.

Apart from the only problem of signature verification. Everything else is better in Evince compared to Adobe on my personal usage. Let me know your views and experience on this. Leave your opinion in comment section.

Published Paper at Rajagiri Management Journal | Modelling Non - Normality and Consistency of Returns Distribution of Major Industries in BSE
Paper pubslished at esteemed Rajagiri Management journal published by Rajagiri Centre for Business Studies located at Kochi - India. The paper is an attempt to study the normality as well as non-normality of returns in industries listed in BSE. More over this study tries to establish a consistency index for returns based on risk return framework by using the data envelopment analysis. The results of the study gives an insight that the each industry follows separate statistical distribution which explains that the nature of returns differs from one another and consistency index gives an insight to the investors that there is an opportunity to achieve good returns due to the consistency in the returns of Indian industries listed in BSE.

Installing R for Linux (Ubuntu, Mint, Debian, Fedora)

Installing R in Linux

R is an open source programming language and software environment for statistical computing and graphics that is supported by the R Foundation for Statistical Computing. It is widely used among statisticians and data miners for developing statistical software and data analysis. Polls, surveys of data miners, and studies of scholarly literature databases show that R's popularity has increased substantially in recent years. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS. 
In this post I will explain you simple steps to instal R in Linux Distros such as Debian and Debian based distros ( Ubuntu, Mint and etc..) , Reh HAt Linux and RHL based distros (Fedora) and Open Suse.

Installing R in Ubuntu / Debian / Linux Mint

1. Open Terminal 
2. In terminal run the following command:
                  sudo apt-get update
        sudo apt-get install r-base r-base-dev
r-base will install R in your system and r-base-dev is for users who need to compile R packages from source.

Installing R in Fedora

1. Open Terminal
2. In terminal run the following command:
                 sudo yum install R
This command will install R that includes 'R-core' and 'R-core-devel'.



In further post I will explain how to install R Studio for Linux users.
