Trilobite biofacies of the Cambrian-Ordovician boundary interval in northern North America

Regional biofacies analysis has been neglected in biostratigraphic studies of the Cambrian-Ordovician boundary interval. Cluster analysis of relative abundance data of trilobites in thirty-seven large collections from ten localities in North America outlines eleven biofacies in the mid-Trempealeauan to early Tremadocian interval. The biofacies are largely lithofacies-specific and are differentiated at generic and familial levels. The composition of trilobite zonal associations in the boundary interval is controlled principally by the sequence of biofacies. Available trilobite zonal schemes can be used only within single lithofacies. The biofacies patterns and faunal dynamics across the upper boundary of the Ptychaspid Biomere do not support hypotheses requiring catastrophic events. In coherence and geographic distribution, Late Cambrian trilobite biofacies are similar to post-Cambrian benthic biofacies.     

Late Quaternary ostracods from Lake George,New South Wales

Fossil ostracods from the uppermost 3m of core LG4 from Lake George all have modern living representatives. This part of the core is thought to represent deposition during the last 60,000 years (see Singh et al., 1981b) and the lake hisotry is traced from a knowledge of the ostracod ecology.

The following distinct phases, and their respective timing, are postulated for Lake George (the timing of events should be considered with caution as few ¹⁴C dates are available): water fresh and lake full for the periods of 10,200 – 12,000 yBP and 19,100 – 20,700 yBP, water fresh, ephemeral at times, for the periods of 3,200–4,000 yBP, 7,000 yBP, 7,500 yBP, 8,500–10,200 yBP, 12,000–13,500 yBP, 20,700–23,500 yBP, 23,800–27,600 yBP and at some stage between 27,000 and 60,000 yBP; ephemeral saline water for a few short episodes between 3,200 and 4,000 yBP and for the periods of 15,600–17,400 yBP and 23,800–27,600 yBP; lake definitely dry between 17,400 and 19,100 yBP.

Data obtained from the ostracods correlate reasonably well with those of lake level fluctuations based on the study of ancient shorelines by Coventry (1976) and others based on facies analyses and the record of plant microfossils by Singh et al. (1981b).     

Betwixt and Between: Trauma,Survival and the Aboriginal Troopers of the Queensland Native Mounted Police

ABSTRACT

Much has been written about the history of the Queensland Native Mounted Police, mostly focussing on its development, its white officers, how much the Colonial Government genuinely knew about the actions of the Force, and how many people were killed during the frontier wars. Far less attention has been given to the Aboriginal men of the force, the nature of their recruitment, and the long-term traumatic impacts on Aboriginal peoples’ and communities’ psyches rather than broadscale changes to Aboriginal culture per se. This article examines the historical and ongoing psychological impacts of dispossession and frontier violence on Aboriginal people. Specifically, we argue that massacres, frontier violence, displacement, and the ultimate dispossession of land and destruction of traditional cultural practices resulted in both individual and collective inter-generational trauma for Aboriginal peoples. We posit that, despite the Australian frontier wars taking place over a century ago, their impacts continue to reverberate today in a range of different ways, many of which are as yet only partially understood.     

Policing authoritarian neoliberalism in South London

In pointing out the exclusionary and nondemocratic reconceptualization of states following the financial and Eurozone crises, research by geographers and critical political economists on authoritarian neoliberalism (AN) has shed light on key state transformations. Exploring the criminalization of council estates and the policing of three austerity-ridden south London districts, this article contributes to efforts to expand the concept of AN further by centering questions of violence and physical state power in the form of discourses and practices of (criminal) punishment and policing. Building on qualitative work with local young people and interviews with former police officers, community leaders and activists, I demonstrate the spatial dimension of AN and the role of policing logic and mechanisms for its administration in south London. I argue that through post-crisis austerity measures and long-term mechanisms of criminalization, young people perceive their home neighborhoods as insecure and alter how they navigate them. Further, I show that spaces of inclusion and welfare, such as social housing estates and schools, have been reimagined as sites of exclusion and punishment, often administered by police.     

The Role of Provinces,States, and Territories in Shaping Federal Policy for Indigenous Peoples’ Health

ABSTRACT

Under both Canadian and United States law, the availability and quality of healthcare and health services to Indigenous peoples are primarily a federal responsibility. Nevertheless, sub-national authorities—most importantly provinces, states, and territories—play a crucial role by virtue of covering (often through federal mandate) services, and regulating health facilities and health personnel off-reserv(ation). While both federal governments have undertaken efforts to transfer, within their fiduciary obligations, their responsibilities for Indigenous peoples’ health to the management of Indigenous peoples themselves, that transfer has considered or included provincial, state, and territorial authorities and resources unevenly, and, in some cases, in tension with the objectives of respecting standards for quality and access. This article applies the methodology used by Canadian researchers of the sub-national health authority issue to the health transfer experience in the United States. The article summarizes findings that demonstrate similar deficiencies as those present in the Canadian transfer process. The article further outlines the experiences of Hawai`i and Ontario as offering models through which to address some of these deficiencies. The article finally suggests that there is a positive relationship between greater participatory models adopted by provinces, states, and territories and better health outcomes among Indigenous groups so included.
