Nutrition and Food Sciences - Houston: Additional Resources

The Houston NFS student, faculty and staff will find practical information on nutrition and food sciences.

I Need a Few Good Articles, Please!

First, get your subject in mind, like "Could obesity be caused by a virus?" This is the most important step (and the hardest)

Next, try the world's biggest health sciences database, called PubMed. Do a MeSH (click it) search; input obesity, click the word, then Add to Search Builder & click Search PubMed. Go back to MeSH, input viruses, click the word, then Add to Search Builder & click Search PubMed. Click Advanced & combine (click add) Obesity and Viruses to see the result, which you click. Refine the results on the left of the Results page by year (last 5 years) fulltext, language, ages, controlled clinical trials or whatever you prefer to find a few good articles.

Click Send to and send to your RefWorks account to help design a beautiful References list to attach to your great paper.

Comparison Groups

Look Local

Look for local county or parishes to find statical data on information, sometimes down to the block level.  You can find data similar to 'the number of white women aged 18-30 who gave birth in X year" this way.  Look for local charity organizations (United Way, America's Charities, etc.) to find more data.

Take a Nap!

TWU Libraries, in conjunction with the Student Union, Student Services and Student Life,  have a nap pod for you to use for 20 minute power naps in the ARC.Former ARC Library Student Assistant and MOTS Ms Kristen McManus demostrates the nap pod use. Reserve the nap pod at on the Houston nap pod button, and you can have a 20 minute power nap to enjoy peaceful, restful sleep.

APA 6th Edition Style Help

The American Psychological Association (APA) Publication Manual, 6th edition, published in 2010, has been updated. When citing sources found online (electronic), the reference listing requires a prefix to the DOI:  This update is available through TWU Libraries.

An example of this is:

Kondo, T., Kishi, M., Fushimi, T., Ugajin, S., & Kaga, T. (2009). Vinegar intake reduces body weight, body fat mass, and serum triglyceride levels in obese Japanese subjects.Bioscience, Biotechnology, and Biochemistry, 73, 1837-1843.

The difference is that the old format had the letters doi and then a colon (:) as a prefix to the number; this annotation is out of date and replaced by the component. This updates parts of APA chapters 6 and 7, especially 6.14, 6.30, 6.31, 6.32, 7.01 through 7.11.

The rationale is that the DOI, developed by publishers, has further developed improved stability in linking to registration sources (like, but not limited to CrossRef at for access their materials.

Caveats are that DOIs are still optional, some publications have no DOI, other publishers have retrospectively assigned DOIs (to older articles), and some webpages have DOIs.  Remember, too (per APA Publication Manual, 6th edition example 7.01, item 3, “Journal article without DOI . . .”) if there is no DOI and the item was obtained electronically, the Reference list citation uses the URL of the journal home page.
