Conflict in Common: Heritage-making in Cape York     

Nick Skilton  Michael Adams  Leah Gibbs 《The Australian geographer》2014,45(2):147-166

The outstanding natural and cultural values of Cape York have been acknowledged for decades, but those decades have been characterised by deep conflict. Non-government organisation intervention in local politics has seen a forceful push for nominating some or all of the Cape York Peninsula as a World Heritage Site. We illuminate the authorised heritage discourse at work in heritage-making, and highlight contested issues of ownership, governance, authenticity, and value. These themes contribute to the possibility of marginalising the voices of local people who wish to contribute to heritage-making in Cape York. Politics infuses all aspects of heritage-making in Cape York, and the specific experiences on Cape York reflect larger political processes occurring in World Heritage discourse. The paper draws on interviews undertaken in May and June 2012.  相似文献   

Emerging Geographies of Conservation and Indigenous Land in Australia     

Heather Moorcroft  Michael Adams 《The Australian geographer》2014,45(4):485-504

International examples of interactions between Indigenous peoples and the new conservation paradigm come mainly from developing countries and suggest divisions over priorities. As a Western settler society, Australia is at a critical time in conservation and Indigenous peoples' rights. Innovative approaches to conservation are promoted. The role and influence of non-governmental organisations is increasing. Indigenous peoples' rights to land are recognised and Indigenous involvement in conservation is growing. Yet, despite Australia being considered a leader in these arenas, particularly the latter, there has been little analysis of the relationship between innovative approaches to conservation and Indigenous Australians under the new paradigm. This paper describes how the spatial manifestations of approaches under the new conservation paradigm and Indigenous land in Australia are creating new geographies. We identify geographies of overlap, dichotomy and absence. The paper identifies research needs into these geographies, including: examining the influence of ‘recognition’ in engagements between conservation and Indigenous Australians; investigating the impacts of approaches under the new paradigm such as scaling-up, territorialism and differing governance structures on Indigenous Australians; and questioning the social responsibilities of the non-governmental organisations towards Indigenous Australians.  相似文献   

Evolution of exhumation and erosion in western West Gondwanaland as recorded by detrital zircons of late Neoproterozoic and Cambrian sedimentary rocks of NW and Central Argentina     

Hubert Miller  Christopher Adams  Florencio G. Aceñolaza  Alejandro J. Toselli 《International Journal of Earth Sciences》2011,100(2-3):619-629

The evolution of the provenance areas for Late Neoproterozoic, Cambrian and Early Ordovician sedimentary and meta-sedimentary rocks of north central and northwest Argentina is discussed using 123 maximum ages of detrital zircons from 42 samples from this and previously published studies. Most detrital zircon ages fall into two groups: 1,200–900 Ma and 670–545 Ma. These ages are essentially identical for the non- to very low grade metamorphic late Neoproterozoic to Early Cambrian Puncoviscana Formation and the low to high grade metamorphic rocks of Eastern Sierras Pampeanas. Hence, both units are related to similar provenance areas at the same time of sedimentation. The time span from zircon crystallization in the Earth’s crust to exhumation and erosion may be very long. This is important when determining maximum ages of sedimentary rocks. Variation of zircon maxima may also be influenced by concurrent sedimentary cover of proposed provenance areas. For the late Mesoproterozoic to early Neoproterozoic zircon age group, an active mountain range of the southwest Brazilian Sunsás orogen is the most probable provenance area. The younger, late Neoproterozoic zircons are related to the continuously developing mountains of the Brasiliano orogen of southwest and south central Brazil. Young zircons, up to 514 Ma, from fossil-bearing Puncoviscana and Suncho Formation outcrops are related to late Early Cambrian volcanism contemporaneous with sedimentation. This situation continues through the Late Cambrian to the Early Ordovician, but the Sunsás orogen provenance diminishes as possible Río de la Plata craton origins become important.  相似文献

Geographers in Business,Government, and Nonprofit Organizations: Skills,Challenges, and Professional Identities     

M. Beth Schlemper  Joy K. Adams  Michael Solem 《The Professional geographer》2013,65(3):480-492

This study examines the experiences of geography graduates who work in business, government, and nonprofit organizations. We analyzed 352 logs from eighty-two professionals detailing professional activities, challenges, and opportunities during one work week each month, over a period of six months. Our analysis explores interpersonal relationships and working conditions affecting participants’ progress toward work goals, workplace climate, and professional identity. Geographic information systems and technology accounted for more than half of the geographic skills respondents reported using on the job, and administrative and leadership factors were the most commonly cited types of transferable skills. Professional geographers value collaborative workplaces as well as opportunities to work independently with the confidence of their supervisors, and their sense of a professional identity is enhanced when they feel valued and are recognized for their work. Professional development activities are important because they reinforce geographers’ sense of positively contributing to their organizations, enhance interpersonal interactions, facilitate work on specific projects, and expand individuals’ knowledge and skills. Moreover, our findings suggest that nearly half of the reported workplace difficulties could potentially be reduced or eliminated as a result of more and better professional development. Nonetheless, many employers do not consistently provide opportunities for professional development to their employees. Based on our analysis, we contend that professional development is a beneficial investment for lifelong learning, from undergraduate and graduate education throughout the entire course of a professional career.  相似文献   

Neoliberalisation,rural land trusts and institutional blending   总被引：1，自引：0，他引：1  

Ian D. Hodge  William M. Adams 《Geoforum》2012,43(3):472-482

In the context of rural land conservation, neoliberalisation involves an increasingly wide range of changes in formal and informal institutional arrangements. These affect the relationship between the state and the market in a variety of ways and have different implications for the governance of rural land. In the context of rural land conservation in the UK, we identify a broad range of changes to policy that promote altered ownership and market related institutional forms, all of which might be seen as forms of neoliberalisation. In some instances these promote market forces and private ownership, while in others they push back the market and support collectivisation. We argue that the complex processes of the decomposition property and reassignment of property rights and the emergence of new forms of governance and partnership are better characterised in terms of institutional blending.  相似文献   

Assessment of perfluorinated compounds (PFCs) in plasma of bottlenose dolphins from two southeast US estuarine areas: relationship with age, sex and geographic locations     

Fair PA  Houde M  Hulsey TC  Bossart GD  Adams J  Balthis L  Muir DC 《Marine pollution bulletin》2012,64(1):66-74

Plasma PFCs were measured in 157 bottlenose dolphins (Tursiops truncatus) sampled from two US southeast Atlantic sites (Charleston (CHS), SC and Indian River Lagoon (IRL), FL) during 2003-2005. ∑PFCs, perfluoroalkyl carboxylates (∑PFCAs), perfluoroalkyl sulfonates (∑PFSAs) and individual compounds were significantly higher in CHS dolphins for all age/sex categories compared to IRL dolphins. Highest ∑PFCs concentrations occurred in CHS juvenile dolphins (2340 ng/g w.w.); significantly higher than found in adults (1570 ng/g w.w. males; 1330 ng/g w.w. females). ∑PFCAs were much greater in CHS dolphins (≈ 21%) compared to IRL dolphins (≈ 7%); ∑PFSAs were 79% in CHS dolphins versus 93% in IRL dolphins. PFOS, the dominant compound, averaged 72% and 84%, respectively, in CHS and IRL dolphins. Decreasing PFC levels occurred with age on the bioaccumulation of PFCs in both sites. These observations suggest PFC accumulation in these two dolphin populations are influenced by site-specific exposures with significantly higher levels in CHS dolphins.  相似文献   

The eccentric frame decomposition of central force fields     

Jared M. Maruskin  Daniel J. Scheeres  Fred C. Adams  Anthony M. Bloch 《Celestial Mechanics and Dynamical Astronomy》2008,100(1):43-62

The rosette-shaped motion of a particle in a central force field is known to be classically solvable by quadratures. We present a new approach of describing and characterizing such motion based on the eccentricity vector of the two body problem. In general, this vector is not an integral of motion. However, the orbital motion, when viewed from the nonuniformly rotating frame defined by the orientation of the eccentricity vector, can be solved analytically and will either be a closed periodic circulation or libration. The motion with respect to inertial space is then given by integrating the argument of periapsis with respect to time. Finally we will apply the decomposition to a modern central potential, the spherical Hernquist–Newton potential, which models dark matter halos of galaxies with central black holes.  相似文献   

Imaging of long‐range reverberation from ocean basin topography     

Fred T. Erskine  Gary M. Bernstein  Edward R. Franchi  Budd B. Adams 《Marine Geodesy》2013,36(1):69-78

A technique is currently under development a the Naval Research Laboratory for imaging of backscatterec acoustic returns from ocean basin topography. The method is straightforward. An explosive sound source is detonated near the center of an ocean basin and the round‐trip travel time from source to reflectors and return is measured. Distance to back‐scattering topography is assumed to be proportional to round‐trip time, with a proportionality constant equal to half the sound speed. A multielement receiving array is used to determine the azimuthal directions to topographic features. Reverberation data are output to an imaging system to study the spatial distribution of sea bottom reverberation. The images are in the form of two‐dimensional maps of backscattered acoustic energy. Typical maps are larger than 2,000 km x 2,000 km (or area coverage greater than 4 x 10⁶ km²). After correction of maps from individual shot detonations for range‐dependent propagation losses, we average ("integrate") maps together on a pixel by pixel basis for a clear picture of major basin reverberators.  相似文献
