As an editor for peer-reviewed journal, what would you consider appropriate in making a decision to accept a peer-reviewer's report?
When evaluating a peer-reviewed study on surface water resources used for a commercial water operation, it is expected that the reviewer will thoroughly assess the methodology, including water sampling procedures and data analysis. In addition, the reviewer should identify potential oversights and suggest necessary improvements or alternative methods. However, when an expert reviewer raises concerns, and the authors respond with contrary submissions supported by well-detailed references, how...

Could salary be used as a surrogate for smoking when sample data are lacking?
In epidemiology cohort studies, information on smoking status is often times lacking for the study sample, which makes it challenging to characterize the effects of other risk factors on endpoints that are causally related to smoking (e.g., lung cancer mortality). Given the strong inverse reported for smoking and income, could salary be used as a surrogate for smoking when direct data are lacking? or would potential relationships between salary other risk factors (e.g., health care access)...

Are there concrete examples that genomics research or genomic selection led to superior crop cultivars?
Numerous articles predict that genomics research and genomic selection would accelerate plant breeding. We have been conducting a study to see how much more effective is genomic selection relative to conventional visual selection in plant cultivar development for a number of years and are about to write a summary article. We are interested in knowing similar researches and their results and conclusions.

Do chronic studies in two species provide significant value in drug development?
Chronic studies in rodent (6 months) and non rodent (9 months) are required for approval of a new drug. Results of these studies are not required until the NDA is submitted, i.e. all the clinical trials are complete. The results of these studies are rarely included in the drug label. Since we generally have subchronic data in two species and long-term exposures in carcinogenicity studies, are the required chronic studies adding to patient safety?

A Ping is a single science-based question. The question comes from a fellow SciPinion Expert who is seeking input from the expert community. All participation in this service (i.e. asking or answering questions) is voluntary and anonymous if you prefer.
Can I post a Ping?
Yes, all SciPinion Experts are able to ask questions for the expert community to answer, provided you have Ping Credits. All Experts start with 3 Ping Credits (i.e., can ask 3 questions), and have the opportunity to earn more (e.g., by answering Pings from other experts, applying to panel opportunities).
Can I sponsor a Paid Ping?
Yes, please contact SciPinion if you would like to sponsor a Paid Ping.
What do I get for answering a Ping?
By answering a question from a fellow SciPinion Expert you earn 1 Ping Credit, which allows you to sponsor your own Ping (e.g., for every question you answer, you can ask your own question)
You also receive the satisfaction of helping your fellow experts and supporting the scientific community.
