An expert is a man who has made all the mistakes which can be made, in a narrow field.
– Niels Bohr
Quite interestingly graduate studies usually take about 5 years total in order to obtain a PhD. It can sometimes be one year less or one or a few years over (too long is usually not seen as a good sign however). Assuming that this is basically your full time occupation, have you notice that at the end of this time frame, you will have reached about 10000 hours of dedicate training in your field.
It is this time of the year when, as a student, you get into two contradicting phases: party and exam. Since you have a tendency to put everything on Facebook, especially a nice evening partying, please do find a better reason for not being present in class the next morning…
If we knew what it was we were doing, it would not be called research, would it?
– Albert Einstein
How do you know for sure that you are at a particularly interesting stage of your thesis project?
When the excitement spread to your supervisor, fellow students and the extended team (collaborators and others). When you present at a meeting and peoples come talk to you with that look in their eyes. When you are asked by scientists or other students unrelated to your project if you have published/submitted your results.
The flip side of that coin is that the pressure is on you (and your supervisor) to convert in a timely fashion to peer-reviewed publications 😉
“Practice is the best of all instructors”

Back from the AAPM scientific meeting, and kudos’ to the organizers for an excellent meeting. Over the past few years, they have set-up a “Best in” category regrouping the 5 highest scored abstracts in each 3 broad categories of the meeting. Not only do they get oral presentations but they also deserved a special poster viewing session. An extremely interesting and exciting session!
You’ve been working hard, around the clock to get all the data out. You might even have submitted an abstract about your current to the great scientific meeting of your field (and maybe got to travel and present it). Now is time to plant the flag, leave your mark i.e. publish!
I have been publishing scientific manuscripts for the past 22 years. My educated comments with regard to journal impact factor has always been the same (If you do not know what JIF is, please have a look at this Wikipedia entry). First order, you should publish in the most important journals for your field. If their JIF are low, who cares as long as your work is important to your field and well cited. For example, the scientific discovery of 2012 according to Science (very high JIF) is the publication of the experimental finding of the Higgs boson… in Phys Lett B (low JIF relative to Science)!
Do not forgot that from an historical perspective, we are awfully bad at predicting what will be the next important discovery down the road. A number of fundamental discoveries and early engineering feats were discarded at first. Similarly there are numerous example of scientists having had tremendous issues in getting those game-changing results published, even those ending up winning Nobel prizes. Karry Mullins’ PCR work is one of many examples of work was rejected by journals having top JIF but for which the application of this very technique was published in Science and Nature and the citations counts of these second generation papers also receiving higher numbers than the original, award-winning work!)
Now, you do not have to agree with this lone scientist opinion but certainly you should have a look at the The San Francisco Declaration on Research Assessment or DORA petition, which is supported by the “big boys” (no discrimination intended). The declaration statement is actually a very interesting read and it covers the historical origin of the JIF (which was not for evaluating researchers at all) and further call for dropping journal-based metrics in assessing scientific productivity for funding and promotion. Over 240 organizations and 6000 individuals have already signed the declaration.
In conclusion, do not loose a good night sleep over your favorite journals’ impact factors…
