The reality of reduction experiments and the GIUR: reply to Eren and Sampson

There is no ambiguity in the existing empirical support for a GIUR as a robust predictor of mass lost from flakes through unifacial retouching. We demonstrate why the GIUR is a reliable method for inferring mass loss, in appropriate circumstances, and why it is a more powerful predictor of mass loss than touted competitors. We explain why Eren, M.I., Sampson's, G. [2009. Kuhn's geometric index of unifacial stone tool reduction (GIUR): does it measure missing flake mass? J. Archaeol. Sci.] arguments are faulty and why researchers should use the GIUR in preference to other methods of estimating the extent of unifacial retouch.     

ENSO influence on Holocene Aboriginal populations in Queensland, Australia

In the Pacific region, the onset of modern El Niño/Southern Oscillation (ENSO) activity at approximately 5000 years ago may have played a significant role in the development of cultures in the Pacific basin. Within Australia, similar trends in population and resource use have been identified but largely ascribed to cultural changes. To test human responses to changing ENSO activity through the Holocene we analysed a comprehensive suite of 710 radiocarbon ages from archaeological sites in ENSO-sensitive Queensland. We observe a dramatic and sustained increase in landscape activity at inland sites from 4860 ± 15 years ago, statistically indistinguishable from the timing of the onset of modern ENSO activity. Subsequent changes in long-term activity directly impacted on human populations indicating that once established, ENSO maintained a continuous influence on disparate cultures throughout the Pacific basin.     

Social geographies of rural mental health: experiencing inclusions and exclusions

A dominant urban focus in previous research on the social geographies of mental health has obscured the experiences of people with mental health problems living in rural localities. Critiquing this urban focus, we report on research conducted in the rural and remote Scottish Highlands. Evidence derived from in-depth interviews with over 100 users of psychiatric services in the Highlands is deployed to investigate the complex socio-spatial dynamics of inclusion and exclusion experienced by these users on a daily basis. A discussion of the explanations that users themselves offer of their experiences is accompanied by a theoretical framing of these issues pivoting on relations of proximity–distance and intimacy–repulsion.     

Trade unions,the Australian Labor Party and the Trade–Labour Rights Debate

This paper examines the Australian trade union movement's campaign to convince the Australian Labor Party (ALP) to support the inclusion of core labour standards in international trade agreements. Despite historical affiliations, the Australian union movement has been unsuccessful in its attempts to influence the ALP. In contrast, the US union movement has convinced both the Republican Party and the Democratic Party to accept that core labour standards should be a part of the trade negotiating agenda. The reasons for the US unions' success on this issue are examined within the context of the changing relationship between the respective union movements and their traditional parliamentary allies. The need for Australian unions to examine and reassess their strategies by drawing lessons from the US experience, including the possibility of a changed relationship with the ALP, is discussed.     

Geographically Weighted Discriminant Analysis

In this article, we propose a novel analysis technique for geographical data, Geographically Weighted Discriminant Analysis. This approach adapts the method of Geographically Weighted Regression (GWR), allowing the modeling and prediction of categorical response variables. As with GWR, the relationship between predictor and response variables may alter over space, and calibration is achieved using a moving kernel window approach. The methodology is outlined and is illustrated with an example analysis of voting patterns in the 2005 UK general election. The example shows that similar social conditions can lead to different voting outcomes in different parts of England and Wales. Also discussed are techniques for visualizing the results of the analysis and methods for choosing the extent of the moving kernel window.     

Language as a public good and national identity: Scotland's competing heritage languages

The preservation of one or several historically and culturally important languages may be a salient political issue in some polities. Although they may not be used as an active means of communication, these languages can also serve a symbolic identitary function. These ‘heritage’ languages can be seen as ‘public goods’ and that even non‐speakers of these languages can have opinions regarding their importance to national identity. In the Scotland example, while Gaelic has been the focus of proactive government legislation and education initiatives, Scots is still struggling for status as a recognised language. Both languages are in some way constituent parts of Scottish identity that at times may seem in competition with one another. Using original survey data, we delve deeper into questions of language, identity and politics in Scotland. First, we describe how public opinion is divided over the importance of Gaelic and Scots to Scottish identity. Second, we use attitudes towards these languages as a dependent variable looking at Scottish identity and attachment. Finally, we use these attitudes towards Gaelic and Scots as an independent variable in models for party identification in Scotland.     

Pre-Columbian Fishing on the Coast of the Atacama Desert,Northern Chile: An Investigation of Fish Size and Species Distribution Using Otoliths From Camarones Punta Norte and Caleta Vitor

The bountiful marine resources of the northern Chilean coast offset the extreme aridity of the Atacama Desert in pre-Columbian times, underwriting permanent human occupation, and providing the basis for a long tradition of marine subsistence. We analyzed fish otoliths (n = 549) recovered from the sites of Camarones Punta Norte (occupied ca. 7,000–5,000 years ago) and Caleta Vitor (occupied ca. 9,500–300 years ago) to investigate species distribution and changes over time. We also estimated the size of the fish based on relationships between otolith weight and fish total length (TL) obtained from modern samples of the predominant species, Sciaena deliciosa. The estimated size range of S. deliciosa from Caleta Vitor included fish that were significantly larger than those from Camarones Punta Norte, with the maximum TL (970 mm) almost double the modern maximum length documented. The fluctuating abundance of fish species and other marine taxa from Camarones Punta Norte indicates intense but sporadic use of the site over the span of occupation. In contrast, human occupation of the Caleta Vitor estuary is more continuous. Comparisons of the fish assemblages with a nearby contemporaneous site, Quebrada de los Burros in southern Peru, suggest that fishing technologies were similar along this section of the Pacific coast.
