The use of hyphen in consecutive compounds [duplicate]

Both questions have quite an easy answer: it depends on the style guide you have to adhere to for your research (it’s unclear whether it’s an article, a thesis, for a book, or something entirely different).

Individual(-) and project-related

Your first question is about what is known as a suspension hyphen (or sometimes a suspended hyphen), which indicates that the word it ends is the left base of a compound whose right base has been omitted, usually to avoid repetition. (Note: it’s a hyphen, not a dash.)

Suspension hyphens are very commonly used and not often left out in formal writing, and I would guess that most style guides would advise you to use them when appropriate—especially since leaving them out can make the sentence ambiguous: are we talking about both project-related and individual determinants, or about determinants related to both projects and individual?

The Chicago Manual of Style (5.91.4) says:

If two phrasal adjectives end in a common element, the ending element should appear only with the second phrase, and a suspension hyphen should follow the unattached words to show that they are related to the ending element: middle- and upper-class operagoers. But if two phrasal adjectives begin with a common element, a hyphen is usually inappropriate, and the element should be repeated: left-handed and left-brained executives.

– but you should of course follow the advice of whatever style guide you have to adhere to.

To dot or not to dot

Your second question is really more one of layout and (graphic) styling. If your title will appear on a front page in fancy lettering, the dot can be included or omitted based purely on aesthetic grounds.

If it is going to be a ‘regular’ heading (for example the heading of an article in a journal), you should look at other similar articles in the journal to see what the accepted practice is. I doubt many style guides include this in their scope, and it is usually left up to the individual journal/series/monograpy/anthology editor(s) how they wish to deal with it.
