Mapping the graduating European dentist to established undergraduate dental education activities at Trinity College Dublin.

INTRODUCTION: "The Graduating European Dentist" Curriculum (GED) was adopted in 2020 by the Irish Dental Council as its new expectation for competencies. The Dublin Dental University Hospital (DDUH) sought to map the teaching activities for its undergraduate dental training programme to the GED. This paper describes the process developed for curriculum mapping. MATERIALS AND METHODS: Guided by historical mapping data and materials on the DDUH's virtual learning environment; teaching activities in a bespoke curriculum mapping system were edited, added and/or deleted to match existing teaching activities currently delivered by staff to students. These activities were then remapped to GED Learning Outcomes. Staff members with oversight responsibilities for a collection of activities then received and provided feedback on reports tabulating the preliminary map. Feedback from staff members around their activities was accommodated to produce an accurate reflection of teaching activities across the 5 years program. RESULTS: A process for mapping existing teaching activities to a new set of curriculum expectations using a bespoke application and several other widely available technologies was established. Informal feedback from staff has been positive and has raised ideas for future opportunities to improve the alignment of educational activities with learning outcomes. CONCLUSION: Other dental schools may find this accounting of the DDUH's efforts useful in guiding their own curriculum mapping.

Effect of Body Size on Methylmercury Concentrations in Shoreline Spiders: Implications for Their Use as Sentinels.

Shoreline spiders have been proposed as sentinels to monitor aquatic contaminants including methylmercury (MeHg). The present study examined the effect of spider body size on MeHg concentrations in shoreline spiders. We collected 6 taxa of spiders belonging to 4 families (orb-weavers [Araneidae], long-jawed orb weavers [Tetragnathidae: Tetragnatha sp.], jumping spiders [Salticidae], and wolf spiders [Lycosidae: Pardosa sp., Rabidosa sp., and Schizocosa sp.]) from the shorelines of 14 human-made ponds at the Lyndon B. Johnson National Grasslands in north Texas (USA). As a proxy for body size, we measured leg length (tibia + patella) of each spider. Spider taxa differed by 3-fold in mean MeHg concentration, and MeHg concentrations in 4 of 6 spider taxa increased significantly with leg length. The present study is the first to demonstrate that shoreline spider MeHg concentrations increase as a function of spider body size. Because spider size may account for some within-taxa variation in MeHg concentrations, future studies that utilize spiders as sentinels of aquatic contamination by MeHg or other biomagnifying contaminants should take spider size into account.
