Nursing - Houston: Additional Resources

This LibGuide is intended to provide information to Nursing students on the Houston campus.

What is Qualitative, Quantitative and Mixed Methods in Research Data?

What is research, and what is qualitative versus quantitative research? What is mixed methods research? Many different homework assignments ask the student to locate qualitative research or quantitative research articles.  See for some definitions. The British Library has a site describing qualitative research.   Also, the US PubMed Central data source has an article describing qualitative research.  Mixed methods research, a combination of different types of research, can be studied at a  US National Institutes of Health information source here.  Different governmental entities describe and support qualitative and quantitative research, including Australia, as described in their National Health and  Medical Research Council site, hereMany resources throughout the world  concern themselves with ethical research conduct, including how to carefully manage individuals who are the subject of research and clinical trials (see NIH Clinical Research Trials and You). The US National Institutes of Health and also the Australian government display a National Statement on Ethical Conduct in Human Research, and the UK government has much information concerning the National Health Service Health Research Authority and more.

Library Liaison

Your library liaison for Nursing in Houston is the person who helps manage what new materials are selected to be added to the TWU libraries collections. The ARC traditionally receives video streaming, DVD, mixed media kits, and other media materials. Information on the process is at   and at and indicates that the 2016 Nursing Library Liaison is  Dr. Joyce Ennis 82-6608,  so contact her when your Houston faculty wish additions to the ARC.

APA 6th ed and DOI Citations

The American Psychological Association (APA) Publication Manual, 6th edition, published in 2010, has been updated. When citing sources found online (electronic), the reference listing requests 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  updated 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, but there is still some acceptance of the older format.

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.
