h-index is an index that attempts to measure both the productivity and impact of the published work of a scientist or scholar. Here, I am going to tell the way through which you can forecast your future h-index.
While presenting this tutorial, I consider that you have a good knowledge of R software, which is one of the rapidly rising open source statistics software. You can get the software here,

Top Five Journals according to Google Scholar are
2. The New England Journal of Medicine
4. The Lancet
This list is based on “h5-index” - “h5-index is the h-index for articles published in the last 5 complete years. It is the largest number h such that h articles published in 2008-2012 have at least h citations each,” according to Google.

You’re sat at your desk, reading a journal article. You see a graph that looks like this:
the first thing that comes to mind? WHAT ON EARTH DOES IT MEAN?!
At this point many people will skip the methods section of their article and head straight to the discussion- But these graphs and techniques aren’t so scary once you understand the science behind them.

The amount of cow dung plopped into the world every day is almost unthinkable, but Tomas Roslin is thinking about it."We can regard it as either an immense waste problem or an enormous ecosystem service," he says. He means that what starts out as a turd in a field turns into a wealth of nutrients for plants—assuming it can make its way below ground. So understanding how dung gets broken down can help us ensure an ecosystem is running smoothly. To address such a messy, large-scale question........ Read more »

There are several steps that researchers can take to bolster the integrity of their work, but embracing the use of the “new statistics” of effect sizes, estimation, and meta-analysis is a particularly important one, argues psychological scientist Geoff Cumming of La Trobe University in Australia....

“If God is possible, then he exists necessarily. But God is possible, therefore he exists”. This is the extreme synthesis of Gödel’s most famous result.

While contemplating the scienciness of homeopathy research and the time, money and effort wasted by misguided homeopathy researchers, I recently came across a paper which represents one such effort; it was published in the Journal of Analytical Methods in Chemistry in 2012, written by two Indian authors, one from the prestigious Indian Institute of Technology in Kharagpur, West Bengal, and the other from a medical college associated with a local district hospital. Intrigued by the title claim of........ Read more »

Is the ability to empathize uniquely human? This question has long been pondered by philosophers and animal behaviorists alike. Empathy depends in part on the ability to recognize the wants and hopes of others. A new study by researchers at the University of Cambridge suggests that we may not be alone with this ability.

Photo: Steven PamThere is an industry in Australia that relies on an integral piece of equipment, but the system behind product development process is flawed, and lives are at stake. From farm dogs to military explosive detection dogs, guide dogs to greyhounds, Australia’s working and sporting dog industry claims a 50-70% fail rate as normal. The welfare of these dogs is intimately linked to their working performance. It can be an emotive topic, so let’s take the emotion out of it and o........ Read more »

I don't think I mentioned this JISC project by David Shotton et al. yet, and should perhaps have done so earlier. But it is not too late, as Shotton is calling out for help in a Nature Comment this week (doi:10.1038/502295a). Now, I have been tracking what is citing the CDK literature using CiteUlike since 2010, and just asked the project developers how I can contribute this data.
Interestingly, the visualization from OpenCitations.net is interesting as it also shows papers citing papers t........ Read more »

When cells are put under stress (e.g. UV light, ionising radiation, reactive oxygen species) they undergo a process known as cellular senescence in which cell division (mitosis) is arrested. This is thought to contribute to ageing. In their 2013 paper Naylor and colleagues outline a strategy to selectively remove in vivo senescent cells expressing p16Ink4A .... Read more »

On 17 October, I travelled to London to participate in the annual Publications Seminars. As suggested by the programme, the presenters focused on discussing changes in the publications industry. One of the most heated debates of the event highlighted a recent sting operation published in Science.1 The researcher, John Bohannon, aimed to uncover how rigorous the peer review process is in open access journals that do not charge their readers for viewing content. John Bohannon wrote a far-fetched f........ Read more »

UK universities are gearing up for REF2014, a nationwide evaluation of research quality, on the basis of which central funding will be determined.
