In this article, the authors present the salient archaeological results of a diachronic, interdisciplinary research project on rural settlement and land use in a region of low mountains in southern Germany. Despite clear locational disadvantages, in particular great distances to drinking water sources, archaeological excavations and an extensive dating programme document an unexpectedly long continuity of prehistoric settlement in the area.

OBJECTIVES/GOALS: Team science competencies are not well-defined for nonfaculty staff of Clinical Research Professionals (CRPs) who conduct research. Using an existing framework, our work has determined skills associated with team science competencies as related to CRPs. Our team also outlined examples of those skills on a fundamental, skilled, and advanced level. METHODS/STUDY POPULATION: The team consists of both CRPs and those working in the Team Science space. This team used a modified Delphi approach to determine the skills and leveling examples of each team science competency. The team broke into four groups and was assigned 3-4 competencies each. Each group determined skills needed to support (exhibit, promote) each competency and then described an example of this skill at the fundamental, skilled, and advanced levels. Once each group was finished with their assigned competencies, they were re-assigned to a different group for review and changes. Finally, team science and CRP experts reviewed the skills and levels. RESULTS/ANTICIPATED RESULTS: Our results are a rubric that defines 3-5 practical skills per described competency. These skills are needed to support and promote each competency as a CRP. An additional outcome from this work includes examples of each skill at the fundamental, skilled, and advanced levels in a CRP’s career. Each leveled example is described in a concise, actionable way using Bloom’s taxonomy. This rubric is meant to be easily understood, very useable and able to be used in conjunction with existing CRP competency frameworks. By using Bloom’s taxonomy, we set the stage for future educational programming in Team Science skill-building for clinical research professionals. DISCUSSION/SIGNIFICANCE: Team science concepts and competencies have been increasingly integrated into translational science teams. However, team science competencies related to CRPs have remained largely undefined. Our work helps to define these competencies for CRPs in a practical way. Our rubric fills gaps in, and builds on, existing CRP competency frameworks.

OBJECTIVES/GOALS: a) Explore topics related to AMC CRP job titles, descriptions, and pre-requisites for hire b) Describe impact of COVID-19 on the AMC CRP workforce c) Discuss opportunities for improving diversity in the CRP workforce d) Discuss opportunities to enhance institutional staffing culture to retain CRP workforce METHODS/STUDY POPULATION: Qualitative data from a series of workshop breakout sessions and open-text survey materials focusing on AMC CRP recruitment, retention and diversity were analyzed to inform content and recommendations for clinical research job titles and descriptions, pre-requisites, diversity, and current needs. RESULTS/ANTICIPATED RESULTS: While certain institutions have established competency-based frameworks for job descriptions and career ladders, standardization remains generally lacking across CTSA hubs. Significant hiring needs have reached exponential proportions across hubs, unable to meet current and projected clinical research goals. Data confirmed an urgent need for closing gaps in clinical research workforce at AMCs, especially for improving diversity and equity of personnel. Improved collaboration with human resource departments, engagement with principal investigators, and overcoming both organizational and resource challenges were suggested strategies, as well as pipeline development via outreach to universities, community colleges, and high schools to raise awareness of the professional pathways for CRPs. DISCUSSION/SIGNIFICANCE: Based on input from 130 CRP leaders at 38 CTSA hubs and 4 IDeA sites evaluating data from 23 breakout transcripts and ~92 surveys from the Collaborative Conversations Unmeeting, new opportunities emerged during the analysis. The findings will be summarized in a 2022 Synergy manuscript including best practice benchmarking recommendations.

We used a Zoom Un-meeting as an educational approach to provide experienced clinical research professional (CRP) adult learners a collaborative learning space to learn more about current issues for academic medical center (AMC) clinical research workforce development and collaborate on solution finding. CRPs operationalize the conduct of clinical trials and represent a significant brain trust for the Clinical and Translational Science (CTSA) consortium hubs with their vast knowledge base, extensive experience, understanding of relevant institutional policy, organizational culture, and clinical research operations. Un-meetings are an intentionally organized and coordinated group activity that encourages participants to focus on a topic and incorporate an open flow of ideas through brainstorming and an open discussion format, setting the stage for future collaborative action. We divided topics into a series of six consecutive monthly Un-meeting Zoom workshops. Ultimately, one resulting output from the meeting was the Center for Leading Innovation and Collaborations (CLIC) synergy paper award to support continued collaborative work. Currently, work teams have emerged to analyze qualitative data from brainstorming and breakout session recordings and to identify small-group activities. We describe this adult learning tool as valuable for exploring issues of AMC CRP professional development. This approach encouraged creative/critical thinking and opportunities for leadership, team science, and problem-solving among participants.

During glacial times, the North Atlantic region was affected by serious climate changes corresponding to Dansgaard-Oeschger cycles that were linked to dramatic shifts in sea temperature and moisture transfer to the continents. However, considerable efforts are still needed to understand the effects of these shifts on terrestrial environments. In this context, the Iberian Peninsula is particularly interesting because of its close proximity to the North Atlantic, although the Iberian interior lacks paleoenvironmental information so far because suitable archives are rare. Here we provide an accurate impression of the last glacial environmental developments in central Iberia based on comprehensive investigations using the upper Tagus loess record. A multi-proxy approach revealed that phases of loess formation during Marine Isotope Stage (MIS) 2 (and upper MIS 3) were linked to utmost aridity, coldness, and highest wind strengths in line with the most intense Greenland stadials also including Heinrich Events 3–1. Lack of loess deposition during the global last glacial maximum (LGM) suggests milder conditions, which agrees with less-cold sea surface temperatures (SST) off the Iberian margin. Our results demonstrate that geomorphological system behavior in central Iberia is highly sensitive to North Atlantic SST fluctuations, thus enabling us to reconstruct a detailed hydrological model in relation to marine–atmospheric circulation patterns.

The appearances of palaeosurfaces intercalated into palaeo-dune fields on Fuerteventura are multifaceted. Although reddened layers in these dune sediments might suggest that strong soil-formation processes have taken place, the combination of aridity and parent material, namely biogenic carbonate sand of shelf origin, reveals that strong soil formation seems unlikely. These sediments rather represent de- and recalcification processes only. Solely in the case of admixed material of volcanic origin and dust deposits further soil-forming processes seem to be possible. Hematite-rich Saharan dust contributes to reddish colouration of the palaeosurfaces. In addition, CaCO3-coated iron particles appear to be ingredients of dust being leached after deposition and transformed to hematite. Overall, we propose much weaker soil-forming processes during the Pleistocene than previously postulated. Our findings support the relevance of local environments. Carbonate sands of shelf origin hinder strong soil formation and the reddish layers separating dune generations are palaeosurfaces, which mainly consist of Saharan dust. After deposition of allochthonous material, these layers are overprinted by weak soil-forming processes. The formation of palaeosurfaces primarily depends on morphodynamically stable periods during limited sand supply. Our data suggest a cyclicity of processes in the following order: (1) sand accumulation, (2) dust accumulation and weak soil formation, and (3) water-induced erosion. For the Canary Islands, we support the assumption of glacial maxima being periods of increased levels of moisture. In combination with rising sea level, we propose that favorable conditions of surface stability occur immediately after glacial maxima during periods of starting transgression, whereas regression periods immediately after sea-level high stands seem to yield the highest sand supply for the study area.

The Fezzan Project completed its five-year fieldwork cycle in 2001. The geographical research team located numerous additional palaeolake sites within the Edeyen Ubari, using a combination of Remote Sensing technology and field visits. Additional samples were taken for analysis and dating from many lake edge locations, relating to both the large Pleistocene lake and to the numerous smaller Holocene lakes that have been identified by the team. The excavations at Old Germa were taken down through Garamantian occupation levels to the natural subsoil below the earliest cultural horizon. The earliest activity, represented by a few mudbrick walls and hearths built directly on the natural soil, is believed to date to c. 400-300 BC. Traces of several phases of Garamantian buildings were uncovered, along with numerous rubbish pits, which yielded a rich assemblage of finds, including, for the first time, examples of Garamantian figurines, small 3-D sculptures of humans and animals. Work on the various classes of finds (pottery, small finds, lithics and other stone artefacts, metallurgical evidence, etc.) complemented the excavation work. In addition, a small amount of further survey work was carried out on sites in the Wadi al-Ajal, along with a contour survey of Old Germa and standing building survey at a number of other sites.
