Clovis,Folsom, and Midland components at the Debra L. Friedkin site,Texas: context,chronology, and assemblages

The archaeological transition from Clovis to Folsom and Midland in the North American Great Plains coincides with the end of the Pleistocene and onset of the Younger Dryas. Comparisons exploring the adaptive changes that took place during this period frequently employ regional-scale approaches. The focus on regional-scale analyses largely results from the dearth of sites repeatedly visited by multiple early Paleoindian groups. However, regional-scale comparisons have the potential to overlook smaller-scale differences. The Debra L. Friedkin site, Texas offers an opportunity to study Midland, Folsom, and Clovis technology and site-use at a single site. This paper presents the context and chronology of the Midland, Folsom, and Clovis assemblages and a site-scale analysis of lithics from the Friedkin site. It is argued that point production and late-stage reduction were primary activities, and the use of bifacial cores for flake tools was important throughout these occupation periods. Site use at Friedkin differs from early Paleoindian occupation at the nearby Gault site and expands our understanding of settlement and technological organization in the region.     

Commentary : Partication and representation in the 2002 ATSIC elections

This commentary updates earlier work on participation and representation in ATSIC elections. It adds analysis of the fifth round of ATSIC elections held in 2002 to those held in 1990, 1993, 1996 and 1999. It confirms and refines earlier findings relating to a number of different measures of participation and representation. It argues that overall voter turnout is reasonable given the voluntary nature of ATSIC elections. It discerns a distinctive geography of both voter turnout and candidate interest. It argues that women's participation in ATSIC elections as voters, candidates and in being elected as regional councillors is quite high, but that there is some falling away in women's election to the offices of commissioner and regional council chairperson. It notes some weakness in the representation of women as regional councillors in remote areas and an under-representation of councillors under the age of 35. It also discerns a distinctive geography in the election of Torres Strait Islanders to ATSIC regional councils. In all these instances, the commentary attempts to explain and understand the patterns of participation and representation, while also raising them as possible issues of concern for ATSIC. Explanations relate to ATSIC's program and service provision roles, different social meanings and types of Indigenous identity, the relative influence of European settlement norms on traditional patterns of Indigenous political behaviour, and the nature of public career life courses. The commentary suggests that the distinctive geographies and other patterns of participation and representation are both understandable and well entrenched, and are unlikely to change greatly in the future.     

Digital Dialogue? Australian Politicians' use of the Social Network Tool Twitter

The recent emergence of online social media has had a significant effect on the contemporary political landscape, yet our understanding of this remains less than complete. This article adds to current understanding of the online engagement between politicians and the public by presenting the first quantitative analysis of the utilisation of the social network tool Twitter by Australian politicians. The analysis suggests that politicians are attempting to use Twitter for political engagement, though some are more successful in this than others. Politicians are noisier than Australians in general on Twitter, though this is due more to broadcasting than conversing. Those who use Twitter to converse appear to gain more political benefit from the platform than others. Though politicians cluster by party, a relatively ‘small world’ network is evident in the Australian political discussion on Twitter.     

Full-Scale Experimental Verification of Soft-Story-Only Retrofits of Wood-Frame Buildings using Hybrid Testing

The FEMA P-807 Guidelines were developed for retrofitting soft-story wood-frame buildings based on existing data, and the method had not been verified through full-scale experimental testing. This article presents two different retrofit designs based directly on the FEMA P-807 Guidelines that were examined at several different seismic intensity levels. The effects of the retrofits on damage to the upper stories were investigated. The results from the hybrid testing verify that designs following the FEMA P-807 Guidelines meet specified performance levels and appear to successfully prevent collapse at significantly higher seismic intensity levels well beyond for which they were designed. Based on the test results presented in this article, it is recommended that the soft-story-only retrofit procedure can be followed when financial or other constraints limit the retrofit from bringing the soft-story building up to current code or applying performance-based procedures.     

Technological successions in the Middle Stone Age sequence of Diepkloof Rock Shelter,Western Cape,South Africa

The southern African MSA comprises a series of phases of unique technological innovations that fuel current models on the evolutionary processes of Anatomically Modern Humans. However, the nature and variability of these technological phases remain poorly documented. This study reports on the previously unpublished sequence of Diepkloof Rock Shelter (South Africa) and investigates the main technological changes therein, particularly emphasizing the emergence, succession and disappearance of the Still Bay (SB) and the Howiesons Poort (HP). We argue for technological change that occurred at different rates and under the influence of variable driving factors. Our model implies that the SB and the HP are not related to the influx of new populations but have regionally specific origins. Unlike the other techno-complexes, the HP at Diepkloof is subdivided into different phases (Early, Intermediate and Late) but only the upper phases resemble the so-called “classic” HP. Finally, the technological sequence of Diepkloof questions the homogeneous picture which has been so far assumed for the southern African MSA and places emphasis on the importance of exploring long regional sequences.     

Participation and Representation in ATSIC Elections: A 10 Year Perspective

This paper examines participation and representation in ATSIC elections over the 10 year period since 1990. It attempts to identify patterns of participation and representation that seem to be emerging and what these might suggest about ATSIC's operation. By examining numbers of nominees compared to positions available, the paper suggests that ATSIC elected office has been fairly keenly and consistently sought and competed for by Indigenous people, though there may have been some slight initial reticence in the 1990 elections. By examining voter numbers and voter turnout, the paper suggests that voter participation nation-wide rose slightly from 1990 to 1996 and then largely stabilised in 1999. It also suggests that there have been significant variations from this national pattern at State and Territory levels and it explores some reasons for this. The paper also examines voter numbers and voter turnout at the ATSIC regional level since 1993 and finds that there has been much higher voter turnout in the sparsely settled regions of northern Australia and much lower voter turnout in the southern and urban areas. This is explained in terms of ATSIC program and expenditure priorities and in terms of polling place access. The final two sections of the paper examine the representation of women and Torres Strait Islanders among ATSIC elected representatives. Both are seen as significant issues which should be of some ongoing concern within ATSIC, alongside the issue of the southern/northern difference in voter participation.
