Webpage Title Missing Space

Hi, all,

The titles on every page on my WordPress blog are slightly malformed. The home page’s title is “TitleTitle”. Each post’s title element is “TitleTopic”. Note that there is no space between those words.

I think maybe a more appropriate text to prepend to each title is “Title – “. How do I change this?

For examples of what is going wrong here is my blog’s home and here is an example post. You can see this slightly malformed title tag’s content on the top of your browser window, depending on which browser you are using.
