Reconstructing Iron Age Community Dynamics in Eskisehir Province, Central Turkey

Current understanding of the Iron Age polity of Phrygia in Central Anatolia is primarily based on excavations and survey in the region of the Phrygian capital of Gordion. In order to expand our knowledge of the Phrygian polity, we assess the scale and nature of Iron Age communities in the western (EskiAYehir) region of Phrygia. We address the challenge of interpreting ceramics derived from large-scale archaeological survey by utilizing Neutron Activation Analysis (NAA) of ceramics from 12 sites across the region collected by the EskiAYehir archaeological survey project as well as an excavated assemblage from Aar Hoyuk. While the uniformity in ceramic technology and styles suggest the region is part of the larger Phrygian community, NAA results reveal that (a) ceramic production was regionally highly localized with limited evidence of standardization during the Iron Age and (b) based on evidence of community interaction it is possible to establish a partial chronological sequence of development. These results have implications not only for understanding the internal dynamics within the Phrygian core but also for developing a methodology for comparing ancient polities using commensurate units of interacting communities. The present study is part of the larger Anatolian Iron Age Ceramics project (http://www.une.edu.au/a-ia).

The Social Principles of Jesus: A Critical Re-examination of Walter Rauschenbusch’s Social Gospel

It has been nine decades since Walter Rauschenbusch (1861-1918) published a slim volume entitled The Social Principles of Jesus. Though today less well known than his other works Christianity and the Social Crisis (1907) and Theology for the Social Gospel (1917), it is Social Principles that most adeptly summarizes the theological ethics of Rauschenbusch’s “social gospel.” Taking the form of a pedagogical treatise, Social Principles reads as both a finely tuned analysis of the modern relevance of the teachings of Jesus, and an impassioned plea on the part of its author for an end to the folly of interpreting Christianity solely in “individualistic” terms. It is Rauschenbusch’s expressed aim to resurrect the core teachings of Jesus, which are social and ethical, and apply these to a renewed, socially conscious liberal democracy, establishing a grand harmony between religion, ethics, and social evolution. How far this vision was from the burgeoning “fundamentalism” of his day (and ours) is more than evidenced by the critical reaction of many of his more conservative peers, but also indicates the continuing relevance of his work for theologians and others looking for alternative paths. The following exposition is supplemented with appreciative and critical comments.

Estimates of Use of Research-Based Instructional Strategies in Core Electrical or Computer Engineering Courses

Many research-based instruction strategies (RBISs) have been developed; their superior efficacy with respect to student learning has been demonstrated in many studies. Collecting and interpreting evidence about: 1) the extent to which electrical and computer engineering (ECE) faculty members are using RBISs in core, required engineering science courses, and 2) concerns that they express about using them, are important aspects of understanding how engineering education is evolving. The authors surveyed ECE faculty members, asking about their awareness and use of selected RBISs. The survey also asked what concerns ECE faculty members had about using RBISs. Respondent data showed that awareness of RBISs was very high, but estimates of use of RBISs, based on survey data, varied from 10% to 70%, depending on characteristics of the strategy. The most significant concern was the amount of class time that using an RBIS might take; efforts to increase use of RBISs must address this.

Catastrophic Flooding In North-Central Pennsylvania: Geomorphic Findings From The September 2011 Event And Their Significance To

Tropical Storm Lee produced 25-36 cm of rainfall in north-central Pennsylvania on September 4th through 8th of 2011. Loyalsock Creek, Muncy Creek, and Fishing Creek experienced catastrophic flooding resulting in new channel formation, bank erosion, scour of chutes, deposition/reworking of point bars and chute bars, and reactivation of the floodplain. This study was created to investigate aspects of both geomorphology and sedimentology by studying the well-exposed gravel deposits left by the flood, before these features are removed by humans or covered by vegetation. By recording the composition of gravel bars in the study area and creating lithofacies models, it is possible to understand the 2011 flooding. Surficial clasts on gravel bars are imbricated, but the lack of imbrication and high matrix content of sediments at depth suggests that surface imbrication of the largest clasts took place during hyperconcentrated flow (40-70% sediment concentration). The imbricated clasts on the surface are the largest observed within the bars. The lithofacies recorded are atypical for mixed-load stream lithofacies and more similar to glacial outburst flood lithofacies. This paper suggests that the accepted lithofacies model for mixed-load streams with gravel bedload may not always be useful for interpreting depositional systems. A flume study, which attempted to duplicate the stratigraphy recorded in the field, was run in order to better understand hyperconcentrated flows in the study area. Results from the study in the Bucknell Geology Flume Laboratory indicate that surficial imbrication is possible in hyperconcentrated conditions. After flooding the flume to entrain large amounts of sand and gravel, deposition of surficially imbricated gravel with massive or upward coarsening sedimentology occurred. Imbrication was not observed at depth. These experimental flume deposits support our interpretation of the lithofacies discovered in the field. The sizes of surficial gravel bar clasts show clear differences between chute and point bars. On point bars, gravels fine with increasing distance from the channel. Fining also occurs at the downstream end of point bars. In chute deposits, dramatic fining occurs down the axis of the chute, and lateral grain sizes are nearly uniform. Measuring the largest grain size of sandstone clasts at 8-11 kilometer intervals on each river reveals anomalies in the downstream fining trends. Gravel inputs from bedrock outcrops, tributaries, and erosion of Pleistocene outwash terraces may explain observed variations in grain size along streams either incised into the Appalachian Plateau or located near the Wisconsinan glacial boundary. Atomic Mass Spectrometry (AMS) radiocarbon dating of sediment from recently scoured features on Muncy Creek and Loyalsock Creek returned respective ages of 500 BP and 2490 BP. These dates suggest that the recurrence interval of the 2011 flooding may be several hundred to several thousand years. This geomorphic interval of recurrence is much longer then the 120 year interval calculated by the USGS using historical stream gauge records.
