  • Modeling success rates from appropriations histories

    Introduction to modeling success rates from appropriations data A substantial portion of fundamental scientific research is government-supported (see my editorial in Science). An important factor that affects the experiences of individual investigators and the efficiency of government funding programs is the likelihood that a given scientific appli… Read More
  • Comparing individual papers from journals with different journal impact factors

    In the previous post, I developed a tool that could generate an approximate citation distribution for a journal given its journal impact factor (JIF). We can now use this tool to address a key question: If you select one paper randomly from a distribution associated with a journal impact factor JIF_1 (Journal_1) and another paper randomly… Read More

    Generation of predicted citation distributions from journal impact factor values

    In my previous post, I demonstrated how the citation distribution for a given journal could be fit to a function defined as the difference of two exponentials. This function is characterized by two parameters, k1 and k2. I showed how these two parameters could be used to derive the journal impact factor (JIF). However, for a variety… Read More

    Journal impact factors –Fitting citation distribution curves

    Introduction to Sciencehound Welcome to my new blog at Science. I began blogging when I was Director of the National Institute of General Medical Sciences (NIGMS) at the US National Institutes of Health (NIH). Our blog was called the NIGMS Feedback Loop. I found this to be a very effective way of sharing information and data with NIGMS stakehol… Read More
