A geometric morphometric relationship predicts stone flake shape and size variability

The archaeological record represents a window onto the complex relationship between stone artefact variance and hominin behaviour. Differences in the shapes and sizes of stone flakes—the most abundant remains of past behaviours for much of human evolutionary history—may be underpinned by variation in a range of different environmental and behavioural factors. Controlled flake production experiments have drawn inferences between flake platform preparation behaviours, which have thus far been approximated by linear measurements, and different aspects of overall stone flake variability (Dibble and Rezek J Archaeol Sci 36:1945–1954, 2009; Lin et al. Am Antiq 724–745, 2013; Magnani et al. J Archaeol Sci 46:37–49, 2014; Rezek et al. J Archaeol Sci 38:1346–1359, 2011). However, when the results are applied to archaeological assemblages, there remains a substantial amount of unexplained variability. It is unclear whether this disparity between explanatory models and archaeological data is a result of measurement error on certain key variables, whether traditional analyses are somehow a general limiting factor, or whether there are additional flake shape and size drivers that remain unaccounted for. To try and circumvent these issues, here, we describe a shape analysis approach to assessing stone flake variability including a newly developed three-dimensional geometric morphometric method (‘3DGM’). We use 3DGM to demonstrate that a relationship between platform and flake body governs flake shape and size variability. Contingently, we show that by using this 3DGM approach, we can use flake platform attributes to both (1) make fairly accurate stone flake size predictions and (2) make relatively detailed predictions of stone flake shape. Whether conscious or instinctive, an understanding of this geometric relationship would have been critical to past knappers effectively controlling the production of desired stone flakes. However, despite being able to holistically and accurately incorporate three-dimensional flake variance into our analyses, the behavioural drivers of this variance remain elusive.     

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.     

Golden age,apathy or stealth? Democratic engagement in Britain, 1945–1950

This article revisits democratic engagement in post-war Britain in a context of debates about political disaffection in the current period. The study systematically reanalysed volunteer writing in the Mass Observation Archive and represents a significant methodological advance on previous studies. Little evidence was found to support common existing interpretations: whether ‘golden age’ narratives of deference to authority, partisan alignment and high voter turnout or revisionist accounts of apathy. Instead, evidence was found of something akin to what Hibbing and Theiss-Morse call ‘stealth democracy’. Citizens thought democracy to be important and felt a duty to vote, but wished for government by experts in the national interest. This ‘stealth’ interpretation builds on existing studies of duty, populism and expertise in twentieth-century Britain. It helps to move discussion of democratic engagement after the Second World War beyond the binaries of self/collective and private/public, and to explain the paradox of high voter turnout in a context of hostility to party politics. It also promises to inform debates about declining political support in the current period.     

Neutral Bystander,Intrusive Micromanager,or Useful Catalyst?

An analysis of Forest Service-related legislative activity found that increasingly Congress is becoming involved in agency activities and decisionmaking. Congress's growing scrutiny and management of the Forest Service is indicated by rising trends in requests for agency testimony at congressional hearings, in the number of Forest Service-related bills and amendments introduced in Congress, and in the amount of Forest Service-related legislation enacted. Anecdotal evidence of direct political pressure imposed upon agency personnel by congressional members also indicates that much congressional influence occurs outside of these legislative activities. An examination of activities such as these and directives attached to annual appropriation bills also shows that not all congressional actions are productive in fostering positive agency change. The results of this study indicate the likelihood that Congress has been playing a major role in instigating change within the agency.     

The Green Frog and Desalination: A Nyungar Metaphor for the (Mis‐)Management of Water Resources,Swan Coastal Plain,Western Australia

ABSTRACT In common with Aboriginal groups around Australia, the indigenous people, or Nyungars, of Perth adopt a holistic attitude towards groundwater resources. Of cultural significance are lakes, springs, soaks and watercourses that feature in Dreamtime creation narratives. Perth is experiencing major water shortages and many Nyungars feel that the degradation of the freshwater supply is a result of mismanagement and unsustainable development by non‐Aboriginal people. Proposals for dealing with the issue are seen as equally out of balance with the natural order of things. Water regulators have much to learn from indigenous Australians about water and environmental management. Although water continues to be central to Nyungar identity, the study on which this article is based found evidence of attenuated knowledge about the Dreaming, with discontinuities evident in the way significance is increasingly being read in everyplace rather than in specific ‘story places’.     

Torres Strait elections, 2000 and 2004: Changes in political leadership and style?

Torres Strait has 18 local governments, elections for which were held in March of both 2000 and 2004 in conjunction with other local government elections in Queensland. Elections were also held at these times for additional positions on two regional representative bodies for Torres Strait, the Island Co-ordinating Council and the Torres Strait Regional Authority. This paper examines all these elections, focusing on changes in political leadership and also a possible emerging change in political style in Torres Strait.
