A Temporal Analysis of the Word 'Impact' in Titles Published in Current science between 1934 and 2015:To what Impact?

The other day, I was trying to retrieve an article I had seen in Current Science (CS) on impact factor and agricultural science publications. I needed it to support a point I was making in my own manuscript. Knowing that it had appeared in the last 2 or 3 years, I started searching for the article. I had no clue about the author or the title, except that it contained the word 'impact' in its title. I browsed the last 2 or 3 years of CS and even after a few tries, was not able to locate it. The only alternative left with me was to consider knocking-off the reference concerned in my manuscript, though this could considerably weaken my argument.
