This research on the early metal ages of the Wadi el-Hasa focuses on settlement systems and attempts to explain how social, economic and political adjustments helped tribal groups survive under natural (i.e., climatic) and anthropogenic (i.e., land degradation, erosion) stress factors. The shifting of subsistence base from agropastoral to pastoral is reflected in site and population densities, diversity of site types, levels of internal complexity, and levels of social organization via the presence of large settlements, like villages, which acted as economic and administrative centers emerge as risk reduction mechanisms.

The cycles of abandonment and resettlement are evaluated within the concept of social reorganization and such changes are assessed as parts of economic revitalization attempts. The social changes that emerge from such shifts are evaluated from the perspective of the scale-free networks modeled and tested through statistical methods, such as ANOVA, for spatial and temporal patterns, while patterns of land use and the impacts of changing climate and anthropogenic activities are evaluated with GIS.

Following the dimorphic society and heterarchic social organization concepts, the discussion emphasizes that tribal groups adjust population density, range and intensity of activities in marginal landscapes, like the Hasa, in order to prevent environmental degradation. These patterns may change once these marginal landscapes are integrated to more complex social organizations. Although this takes place in the Hasa during the Iron Age, the research results imply that environmental degradation did not take place possibly due to the continuation of extensive subsistence patterns, along with the emergence of the long-distance caravan trade as a major economic incentive.

Objective: to explore currently available Open Educational Resources related to Health Sciences programs to increase available options for free, high quality, online educational materials to support Health Sciences faculty, researchers, and students in online, hybrid, and in-person courses at Arizona State University.

Background/Methods: Following the successful Open Access movement, the Open Education movement is expanding free, online access to Open Educational Resources (OERs), beyond research published in scholarly journals. Similar to the Open Access movement, Open Educational resources are of high quality, available for free, online, with minimal or no licensing restrictions. They include, but are not limited to: syllabi and course modules, open textbooks, and massive open online courses (MOOCs). Arizona State University (ASU) has many fully online degree programs from undergraduate to graduate level, as well as supplemental and continuing education certificates. ASU also has many hybrid programs and in-person courses that include online components. Instructors are often searching for online videos or other high quality, online educational materials that they can incorporate in their courses. OERs may provide some useful options. ASU Libraries became involved in Open Education Week in March 2013. To expand on our involvement and increase resource options at ASU, the presenters decided to begin identifying useful OERs for health sciences. To do so, the presenters searched for and evaluated 2-3 sources for OERs each and noted the advantages and/or disadvantages of each, as well as any highly useful specific OERs.

Results: The presenters will discuss the advantages and/or disadvantages of evaluated sources for Open Educational Resources and any highly useful specific OERs identified. We will also provide a brief overview of open source tools related to citation management.

Conclusion: Come to this presentation to explore the Open Education movement: hear about one research university library system's start with Open Education Week, and get an overview of free, online options for high quality Open Educational Resources in the Health Sciences.
