Dealing With Uncertainty In Engineering Design For Large-Scale Gravel Soil Slopes In The Three Gorges Reservoir Zone, Wilson H. Tang, L. M. Zhang, Y. R. Zheng
Dealing With Uncertainty In Engineering Design For Large-Scale Gravel Soil Slopes In The Three Gorges Reservoir Zone, Wilson H. Tang, L. M. Zhang, Y. R. Zheng
Geohazards
The objective of this paper is to first present a general formulation for analysis of uncertainties and evaluation of risks associated with large-scale slopes. The risks may be expressed in terms of the reliability of the system and the consequence. Preliminary studies regarding the mitigation of landslides in the Three-Gorge reservoir zone (TGRZ) of the Yangtze River is presented next. At the normal water level of 175 m, the Three-Gorge reservoir stretches for 665 km along the Yangtze River and extends into many tributaries. Some 684 colluvial deposits, ancient slides and hanging rock blocks, which are larger than 100,000 m3 …
Theoretical Uncertainties In Red Giant Branch Evolution: The Red Giant Branch Bump, Stephan R. R. Bjork, Brian Chaboyer
Theoretical Uncertainties In Red Giant Branch Evolution: The Red Giant Branch Bump, Stephan R. R. Bjork, Brian Chaboyer
Dartmouth Scholarship
A Monte Carlo simulation exploring uncertainties in standard stellar evolution theory on the red giant branch of metal-poor globular clusters has been conducted. Confidence limits are derived on the absolute V-band magnitude of the bump in the red giant branch luminosity function (MV,b) and the excess number of stars in the bump, Rb. The analysis takes into account uncertainties in the primordial helium abundance, abundance of α-capture elements, radiative and conductive opacities, nuclear reaction rates, neutrino energy losses, the treatments of diffusion and convection, the surface boundary conditions, and color transformations. The uncertainty in …

Gambling For Certainty: Luck, Chance, And Uncertainty In Politics, Mindy Peden, Nicole M. Elias
Gambling For Certainty: Luck, Chance, And Uncertainty In Politics, Mindy Peden, Nicole M. Elias

How much of what we do is the result of our will, and how much the result of chance or luck or fortune? This is a decidedly un-decidable question, but one that needs to be asked. The general assumption seems to be that a person's "lot" in life is physically, morally, politically, even romantically linked to choice. But the use of the term "lot" betrays the underlying uncertainty of what "causes" our "lot", laying bare questions of responsibility, burden, and even explanation. Much (perhaps at the very least 50% according to Machiavelli) of what happens in our lives can be …
What Makes And What Does Not Make A Real Option? A Study Of International Joint Ventures, Ilya Cuypers, Xavier Martin
What Makes And What Does Not Make A Real Option? A Study Of International Joint Ventures, Ilya Cuypers, Xavier Martin
Research Collection Lee Kong Chian School Of Business
This paper examines the boundaries of real options logic, with an application to joint ventures (JVs). We distinguish between forms of uncertainty that are resolved endogenously and those that are resolved exogenously, and theorize that only exogenous uncertainty will have the impact predicted by real options theory on a foreign investor's choice of how large an equity share to take in a JV. We theorize that macroeconomic and institutional variables generate exogenous uncertainty whereas, by contrast, cultural distance and choices pertaining to corporate scope and product or process development activities involve endogenous sources of uncertainty that investors can both assess …
Expanding The Conceptual, Mathematical And Practical Methods For Map Comparison, Gilmore Robert Pontius, John Connors
Expanding The Conceptual, Mathematical And Practical Methods For Map Comparison, Gilmore Robert Pontius, John Connors
Geography
Conventional methods of map comparison frequently produce unhelpful results for a variety of reasons. In particular, conventional methods usually analyze pixels at a single default scale and frequently insist that each pixel belongs to exactly one category. The purpose of this paper is to offer improved methods so that scientists can obtain more helpful results by performing multiple resolution analysis on pixels that belong simultaneously to several categories. This paper examines the fundamentals of map comparison beginning from the elementary comparison between two pixels that have partial membership to multiple categories. We examine the conceptual foundation of three methods to …
Implications Of Technological Uncertainty On Firm Outsourcing Decisions, David R. King
Implications Of Technological Uncertainty On Firm Outsourcing Decisions, David R. King
Management Faculty Research and Publications
Outsourcing inherently considers what activity needs to reside within a given firm. The difficulty of exchanges between firms in the face of uncertainty affects where work on developing and producing new products is performed. Theory is developed and explored using a case study that explains firm sourcing decisions as a response to uncertainty within the context of industry structure and related transaction costs. Viewing outsourcing broadly results in a better delineation of outsourcing options. Implications for management research and practice are identified.
