Evaluation of Scholarly Sources

http://pediatrics.aappublications.org/content/126/4/760.full.pdf+html

Purpose: The authors focused on the presence of BPA in dental sealants. Through research, they attempted to answer what can happen to a person exposed to BPA and how people can stay orally healthy without needing BPA-based sealants.

Publishing: The entry was accepted by the journal Pediatrics through peer review on June 11, 2010, and was published onto Web of Science in October 2010.

Sources: The authors consistently paraphrase other research journals such as JAMA, J Am Dent. Assoc., Environ. Health Perspect., and even some online journal articles to build upon their own information.

Authors: The authors are Courtney Chinn, DDS, MPH; Burton L. Edelstein, DDS, MPH; Abby F. Fleisch, MD; Philip J. Landrigan, MD, MSc; and Perry E. Sheffield, MD. 

Audience: Its intended audience is other scholars and doctors wanting to know more about BPA and dental sealants. 

Location: I found it through Web of Science.

Annotation: The authors analyzed how BPA is formed and used, how the presence of BPA and other related substances in sealants and in other objects affects various parts of the human body, and what a person should do concerning sealants. The article is divided into sections to maintain coherence and clarity and included graphs to show examples or data from research. The authors provided many statistics to prove their credibility and many citations to support their evidence. Their purpose is to give some clarity about BPA, share some new research data from studying people affected by BPA, and propose a recommended course of action. This article will be of great use as a document in support of BPA-based sealants.

Purpose: The authors studied the effects of bisphenol A in any situation (including dental sealants) using animals such as rats and monkeys to compare their results to those from humans. They determined if BPA is dangerous to humans, both in adulthood and in childhood, both in non-pregnancy and pregnancy.

Publishing: The entry was received by the journal Reproductive Toxicology in May 20, 2007; revised through peer review on July 25, 2007; accepted on July 26, 2007; and posted online on July 31, 2007.

Sources: The authors cited information from other scholarly journals like the previous article
did.

Authors: The authors are Russ Hauser, Michele Marcus, Nicolas Olea, Laura N. Vandenberg, and Wade V. Welshons.

Audience: Its intended audience is any scholar involved in environmental or medicinal scholars who wanted to know in great detail the risks of being exposed to BPA.

Location: I found the article through Web of Science. 

Annotation: The authors constantly compared the effects of BPA on animals and the effects on humans. Often switching the subject of the sections from animals to humans, the authors  parallelized the two to confirm BPA's effects on organic health by drawing information from other journals and creating large graphs representing their experiments. The purpose of the article is to validate the dangers of BPA exposure for organic life and to figure out the extent of the damage BPA could do depending on one's stage of life. This article can be a great source of information to provide extremely detailed notes on BPA's effects and to show that BPA does not solely concern mankind.
