Publications by authors named "R Paul Beckett"
Disclaimer: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

Thus, the objective of this project was to generate consensus on best practices in creating, administering, and using SCEs.
Methods: A modified Delphi approach was utilized to generate a set of items based on the literature and prior work.
Article Synopsis
- Earth’s rising temperatures due to human activities and solar changes threaten biodiversity, with lichens being particularly sensitive to these climate shifts.
- The study investigates how temperature variations affect lichens by focusing on ergosterol (ERG) and the enzyme involved in its production, squalene epoxidase, highlighting gaps in understanding its regulation during stress.
- Results show that extreme temperatures adversely impact lichen physiology, with significant changes in respiration and membrane integrity at +40 °C and -20 °C, leading to increased expression of certain genes related to sterols and heat stress proteins.
Article Synopsis
- Lichens, key organisms in Arctic and boreal ecosystems, are sensitive to climate change, particularly increased UV light from ozone depletion and deforestation.
- This study investigates how UV-B radiation impacts gene expression in the lichen species Lobaria pulmonaria, highlighting significant browning of the upper cortex and activation of genes related to melanin production for stress protection.
- The findings reveal that lichen symbionts employ a complex gene network for tolerance to UV-B, suggesting that climate change could adversely affect lichen biodiversity through metabolic trade-offs and stress responses.
Objective: To describe the validation and reliability assessment of a rubric designed to assess the participants' teaching portfolios and identify teaching excellence among teaching and learning curriculum (TLC) program participants.
Methods: Following focus groups with program leadership at a single TLC program, an initial rubric was developed, consisting of criteria mapped to 5 domains, to be rated on a 4-point scale. The rubric was then redistributed to the TLC program leadership and external stakeholders for evaluation of face and content validity.
