It depends on the quality of the article and how you are linking from it. Posting low quality articles on any website and using bad linking strategies can have a negative impact on rankings.
When you link from an article on Hubpages you should make sure that the article is unique and offers value to the reader. Make sure it is relevant to the webpage you will be linking to and that a reader would have a reason to click through the link.
To avoid a negative impact on rankings you shouldn't post duplicate or spun content. You shouldn't post links that are not related to the content of the article and you shouldn't post more than one link to the same landing page of a website (in the same article). Also, don't post multiple articles that are on the same topic and have similar content. That will get your account on Hubpages blocked and can hurt your rankings.
