Input: Consider Input: Question: Do why social workers implement decisions to remove children at risk from home?
Answer: Further study is required to examine the generalizability of these findings to other countries, to understand better the reasons for the non-implementation, and to follow-up on the consequences of the non-implementation.

Output: no


Input: Consider Input: Question: Does usability testing found problems for novice users of pediatric portals?
Answer: Despite parental involvement and prior heuristic testing, scenario-based testing demonstrated difficulties in navigation, medical language complexity, error recovery, and provider-based organizational schema. While such usability testing can be expensive, the current study demonstrates that it can assist in making healthcare system interfaces for laypersons more user-friendly and potentially more functional for patients and their families.

Output: yes


Input: Consider Input: Question: Is standards and guidelines for observational studies : quality in the eye of the beholder?
Answer: The lack of observational study standard/guideline agreement may contribute to variation in study conduct; disparities in what is considered credible research; and ultimately, what evidence is adopted. A common set of agreed on standards/guidelines for conducting observational studies will benefit funders, researchers, journal editors, and decision makers.


Output: yes
