Some Insurance Options on Stochastic Drawdowns
… losses. Thanks to its desired features, drawdowns can be a very useful tool in the marketplace, allowing investors to protect against the downside risks which commonly occur in the marketplace. Several insurance products are proposed via including protection against drawdown sizes, speed …

The effect of hydroperiod on seed banks in semi-permanent prairie wetlands
… in this wetland produces more frequent drawdowns and a greater input of mudflat annual seeds. Conversely, seeds of emergent species were more abundant in the seed bank of wetland Pl (48%) compared to P4 (17%). The former wetland has a longer hydroperiod and less frequent drawdowns, and …

Changes in the Potentiometric Surface of the Deep Aquifer in the Joplin Area, Missouri, 1900-Present
… edges of Jasper and Newton Counties. Localized drawdowns are expected to worsen because the populations of these two counties are expected to grow slowly and steadily through the rest of the Twentieth and into the next century, causing water-supply problems for deep well users. It is recommended …

Aquifer Characterization in the Blue Ridge Physiographic Province
… period and produced rapid and relatively uniform drawdowns in surrounding wells completed in the fractured bedrock aquifers. The shallow aquifers experienced minimal drawdowns from the aquifer test indicating low vertical hydraulic conductivity and limited communication between the shallow and …

Cross-sectional and time-series momentum on the JSE
… due to two incidences of extreme and sustained drawdowns. Both incidences occur as a result of the momentum strategy holding market beta exposure of the opposite sign to the market's drastic turn ; the first: positive exposure and market downturn, the second : negative exposure and positive …

Geology, hydrology and hydrogeochemistry of the West Brush Creek Development Area, Beulah Mine, Mercer County, North Dakota
… pits, as well as potential short and long-term drawdowns of the lignite aquifers. The model predicted that both pit-water inflows and drawdowns will be negligible.</p> <p>Three chemically distinct types of groundwater occur within the study area. The most common is the sodium-bicarbonate, …

Fluid and Pressure Dynamics in Natural and Engineered Coastal Aquifer Systems
… cases exhibit larger and more persistent drawdowns, increasing modeled subsidence by 0.2 to 0.5 m after 100 years of pumping. The dissertation also evaluates Managed Aquifer Recharge (MAR) through analysis of the Sustainable Water Initiative for Tomorrow (SWIFT) pilot program in the …

A comparison of electric and hydraulic approaches to fluid flow simulation and hydraulic parameters inversion
… of regular electrical arrays to simulate aquifer drawdowns. By representing reservoir hydraulic conductivities as electric resistors and storativities as capacitors, simulating the potential response gives results similar to that of solving the hydraulic flow equations. Scaling the electrical …

Three Essays in Asset Management: Ethical and Investment Exclusions
… negative screenings can give rise to substantial drawdowns and unintended geographical tilts. We conclude that over the long run the consequences of sector exclusion for investors are likely to be non-trivial. The third chapter conducts a survey of industry professionals’ views on divestments. …

A Numerical and Statistical Analysis of the Fractured Rock Aquifer System in Ploemeur, France to Quantify Local and Regional Recharge
… cubic meters of groundwater extraction, measured drawdowns are marginal, suggesting that local and regional recharge plays a significant role in moderating water-level declines and raising questions as to the origins of the substantial inflow required to sustain this complex system. A roughly …

A time-series and cross-sectional momentum strategy: Dual momentum applied from a South African perspective
… lower standard deviations, lower maximum drawdowns, and yields significant positive alpha. Thus, the core dual momentum strategy and focal point of this study, validates the strategy within a South African context. However, the results of the variations and both supplementary sections …

Development of a Groundwater Flow Model for Hungry Valley, Washoe County, Nevada
… and 30% for Well Nos. 4 and 5 appears to balance drawdowns in the two aquifers. Additionally, it appears that the pumping average from 2000 through 2009 (excluding 2005) of 193 cubic meters/day (57 acre-feet per year) can be supported by the current well field. Future water demand, estimated to be …

Policy Jolts in U.S. Arms Transfers: The Post Cold War Security Environment
… driven by different circumstances than previous drawdowns. The Cold War that had dominated and shaped international affairs was over; the Post Cold War era promised to be a radical departure from the 50-year long status quo. Some phases of the policy jolts were directly related to U.S. Department …

Dynamics and Drivers: Carbon fluxes from temperate freshwater reservoirs
… all of which were accentuated by large water drawdowns during the sampling period. This study suggests that system productivity is likely to be the dominant driver of CH4 and CO2 production in reservoirs of the south east of England, and highlights the significant role of extreme climate …
