I don't think this is exactly what you're looking for, but it's better than Format Painter as far as preserving italics and some other formatting items. Note that I've only tested this with Word 2010.
What you want to do is create a new Style.
So in your example, you would highlight the reference for Miller in its entirety, then select the dropdown icon in Styles on the Home tab. From there you'll select "Save selection as New Quick Style..." which brings up a window to name your new style. Select "Modify..." to confirm that the settings are what you want, and select OK to create the Style.
Then just highlight the items you want to change, and select your new Style from the Styles menu.
As an aside, it appears you're doing technical or thesis writing, and LaTex can make your life a lot easier for that kind of work.
