Find Articles

Use the Library's full text electronic resources listed below to find research articles.

Quick tip: Use formal or scientific terminology. For example, instead of searching for fiber search for "dietary fiber". See the Working with Keywords tab above for other search guidance.

How do articles get peer reviewed? What role does peer review play in scholarly research and publication? This video created by librarians at North Carolina State University Libraries will explain.

Peer Review

Definition

The procedures used by researchers and scientists to review the work, decisions and writings of their professional colleagues - peer groups. Reviewers of scientific papers are commonly called referees, and papers submitted to medical and scientific journals for publication are customarily reviewed by one or more experts in the subject(s) dealt with in the paper. The aim is to improve the quality of the study by pointing out potential pitfalls or errors to the author(s), or to assist medical-journal editors in deciding which papers to prioritise for publication.

Observational and Experimental Studies

An explaination of experimental and observational study designs.

“An interventional or experimental study is when the investigator tests whether modifying or changing something about the study participants alters the development or course of the outcome. For example, if a random half of smokers were given free nicotine patches and the other half were not, an investigator could determine whether free nicotine patches increased the proportion of participants who quit smoking over the subsequent year. The essence of an interventional study is that the investigator has the power to randomly assign exposures in a way that enhances the validity of a study.

Observational studies involve the investigator collecting data on factors (exposures) associated with the occurrence or progression of the outcome of interest, without attempting to alter the exposure status of participants. For example, a study could observe whether smokers are more likely to have a heart attack than non-smokers. The investigator does not intervene or manipulate the situation in any way, he or she simply observes.” (p. 101)
