Translation and Accumulation: Spatial Politics of Parks and Trees in China

This thesis examines two political and distinctly spatial processes in contemporary approaches to the environment in China: translation and accumulation. With China&rsquo;s increasing international environmental leadership, how environmental goals are pursued in China matters&ndash; for the lives of residents in project areas, for climate change, and for the models of environmental approaches that circulate globally. This thesis&rsquo; first chapter develops an analytic of translation through a study on China&rsquo;s new national park system. It explores how Western-based conservationists have been involved in &ldquo;translating&rdquo; the concept and practice of national parks to China. It argues that this translation begins with &ldquo;translators&rsquo;&rdquo; intimate, affective experiences of nature and proceeds through diplomatic &ldquo;speech strategies&rdquo; that show how politics infuse translation at the interpersonal scale. There are of course no &ldquo;direct translations&rdquo; of national parks, and how this translation project &ldquo;lands&rdquo; in Chinese contexts bears effects contingent on geographical and historical particularities. The second chapter examines accumulation in approaches to the environment through the case of Ant Forest, a highly popular app-based project run by Chinese financial technology giant Ant Group that transforms individuals&rsquo; green, low-carbon actions into afforestation projects. The chapter investigates the promise of financial technology (combined as &ldquo;fintech&rdquo;) to solve environmental problems. It finds that Ant Forest, in harnessing fintech, defines &ldquo;green&rdquo; activities more according to political-economic relationships that generate corporate profit, than according to actual environmental benefit, and that in models like Ant&rsquo;s, fintech opens possibilities for novel sites of value production in processes of capital accumulation, especially in articulation with carbon markets, which financialize nature. Translation of national parks and accumulation in Ant Forest illustrate how politics and spatiality are intricately intertwined in approaches to environmental challenges in China today.This research demonstrates that attention to these spatial politics is essential to evaluating both justness and effectiveness in proposals like national parks and green fintech.</p

Seasonal Sediment Migration and Sediment Dynamics on Sandy Point Beach, San Salvador Island, Bahamas

A study of the dynamics of Sandy Point Beach along the southwestern corner of San Salvador Island over an eighteen-month period, beginning in June, 1990, has revealed that two seasonal phases of sediment transport are operative. Based primarily on analyses of the grain-size parameters of sand samples collected from the beach in June, 1990, a northerly direction of sediment transport was detected. This is herein termed the Spring/Summer phase of transport, and it results from the energy of waves generated by the prevailing easterly trade winds. Continued profiling of the beach in December, 1990, and January, 1992, revealed that a strong southerly transport direction is dominant during the fall/winter months.The energy for this phase of sediment transport comes from northwesterly storms. It appears that during such events, large amounts of sediment can be moved rapidly toward the southern end of the beach

A quantified approach to the functional longevity of Geosynthetic Rolled Erosion Control Products (GRECPS)

Geosynthetic Rolled Erosion Control Products (GRECPs) have been utilized for decades in a multitude of applications to mitigate erosion resulting from land disturbance in civil construction projects. GRECPs vary from one type to another, ranging in performance and design life due to their composition and intended purpose. The coverage and durability of the GRECP are fundamental properties that can predict performance and fitness for use. Both coverage and durability will degrade over the design life of the GRECP to the point that fitness for use is unacceptable for the intended application. A standard approach is needed to quantify this material degradation over time. Through this analysis, the degradation of the GRECP’s durability and coverage is predicted over time, field validated, and compared to their respective functional thresholds. The time at which the GRECP’s durability or coverage reduces below the established functional thresholds is known as the GRECP’s functional longevity

Failure to obtain adequate anaesthesia associated with a bifid mandibular canal: a case report

The document attached has been archived with permission from the Australian Dental Association. An external link to the publisher’s copy is included.The inferior alveolar nerve (IAN) block is the most common method for obtaining mandibular anaesthesia in dental practice but it is estimated to have a success rate of only 80 to 85 per cent. Causes of failure include problems with operator technique and anatomical variation between individuals. This case report involves a patient who received IAN blocks on two separate occasions that resulted in only partial anaesthesia of the ipsilateral side of the mandible. Radiographic assessment disclosed the presence of bifid mandibular canals that were present bilaterally and that may have affected the outcomes of the local anaesthetic procedures. Previous studies of bifid mandibular canals are reviewed and suggestions provided that should enable clinicians to differentially diagnose, and then manage, cases where IAN blocks result in inadequate mandibular anaesthesia.K Lew, G Townsen

LITHOLOGIC AND HYDROGEOLOGIC FRAMEWORKS FOR A CARBONATE AQUIFER: EVIDENCE FOR FACIES CONTROLLED HYDRAULIC CONDUCTIVITY IN THE OCALA FORMATION, WEST-CENTRAL FLORIDA.

Facies scale heterogeneity was found to be a dominant control on vertical hydraulic conductivity within the carbonate Late Eocene Ocala Formation of the Upper Floridan Aquifer in west-central Florida. Verification of this conclusion was achievedby establishing a sedimentary and stratigraphic framework for the Ocala Formation and establishing facies-vertical hydraulic conductivity (K2 ) relationships. This two-fold procedure enabled the construction of a hydrogeologic framework for this unit in west-central Florida. The framework, as first proposed here, suggests that the Ocala Formation is a hydrogeologically heterogeneous carbonate body. Logging of seventeen cores and review of more than 300 petrographic thin sections suggest that six wackestone facies , four packstone facies, and two grainstone facies make up the vast majority of Ocala lithologies. Three distinct and mappablesubdivisions or sequences of the Ocala Formation are recognized in west-central Florida and these appear to be correlatable to other Jackson stage sequences recognized elsewhere in the Gulf of Mexico. The three sequences and their component facies architectures indicate subtidal deposition on a distally steepened carbonate ramp during the Late Eocene.</p

Increasing the Resilience and Improving the Environmental Performance of Earthen Flood Defense Structures with High Performance Turf Reinforcement Mat Reinforced Vegetation

Adding resilience to earthen flood defense structures, such as dams and levees, is critical to future risk mitigation as building higher and stronger structures to prevent overtopping waves, storm surge, and flood waters becomes more prohibitive. To add resilience riprap, articulated concrete blocks, concrete slope paving, and other traditional hard armor solutions are often used typically at a great cost to the owner and the environment. The United States Army Corps of Engineers (USACE) sought to mitigate these costs when selecting an armoring system for the earthen levees in the 214 km (133 miles) of the Hurricane & Storm Damage Risk Reduction System for southeast Louisiana. The USACE armoring focus turned to High Performance Turf Reinforcement Mats (HPTRMs) after a levee armored with vegetation reinforced by this synthetic mat in Lafitte, Louisiana survived the storm surge and wave overtopping produced during Hurricane Ike in 2008. This success encouraged the USACE to begin a 10 year intensive research program to determine the hydraulic performance threshold, cost effectiveness, and long-term durability of vegetation reinforced by a HPTRM for adding resilience to the re-built levee system destroyed by Hurricane Katrina. Research at the Hydraulics Laboratory of Colorado State University has established the HPTRM reinforced vegetation performance in both outdoor flume testing and in the world’s largest, full scale Wave Overtopping Simulator. As a result of this research, this paper will focus on using hydraulic data to reposition HPTRMs as a suitable alternative to traditional hard erosion control solutions and explain the importance of key material properties when comparing different HPTRMs. This paper will show that HPTRMs with a more closed structure and a smaller percent vegetation establishment perform better than the more open HPTRMs with a higher percentage of vegetation establishment. More research is required to determine specific design guidelines for correlating percent HPTRM openness to vegetation densities in different soil types as it relates to hydraulic performance. Even with low vegetation densities, HPTRM reinforced vegetation provides improved environmental outcomes and lower carbon emissions when compared to traditional hard armor solutions. Countries around the world may benefit greatly from investing in HPTRM reinforced vegetation to provide resilience on earthen flood defenses as an alternate to traditional hard armor systems that are more expensive, less aesthetically pleasing, and more detrimental to the environment
