Historical Calibration of a Water Account System
Models that are used for future based scenarios should be calibrated with historical water supply and use data. Historical water records in Australia are discontinuous, incomplete and often incongruently disaggregated. We present a systematic method to produce a coherent reconstruction of the historical provision and consumption of water in Victorian catchments. This is demonstrated using WAS: an accounting and simulation tool that tracks the stocks and flows of physical quantities relating to the water system. The WAS is also part of, and informed by, an integrated framework of stocks and flows calculators for simulating long-term interactions between other sectors of the physical economy. Both the WAS and related frameworks consider a wide scope of inputs regarding population, land use, energy and water. The physical history of the water sector is reconstructed by integrating water data with these information sources using a data modelling process that resolves conflicts and deduces missing information. The WAS allows strategic exploration of water and energy implications of scenarios of water sourcing, treatment, delivery and end use cognisant of historical records.water accounting, stocks and flows, historical time series, data modelling, calibration
A Water Accounting System for Strategic Water Management
This paper describes a water accounting system (WAS) that has been developed as an innovative new tool for strategic long-term water management. The WAS incorporates both disaggregated water use and availability, provides a comprehensive and consistent historical database, and can integrate climate and hydrological model outputs for the exploration of scenarios. It has been established and tested for the state of Victoria in Australia, and can be extended to cover other or all regions of Australia. The WAS is implemented using stock-and-flow dynamics, currently employing major river basins as the spatial units and a yearly time step. While this system shares features with system dynamics, learning is enhanced and strategic management of water resources is improved by application of a Design Approach and the structure of the WAS. We compare the WAS with other relevant accounting systems and outline its benefits, particularly the potential for resolving tensions between water supply and demand. Integrated management is facilitated by combination with other stocks and flows frameworks that provide data on key drivers such as demography, land-use and electricity production.water accounts, stocks and flows, water budgets, decision support systems, strategic management

Who is Black Enough For You? An Analysis of Northwestern University Law School\u27s Struggle Over Minority Faculty Hiring
This Article considers the factors that should be used in hiring a person of color to a faculty position and raises the following questions: Apart from potential teaching ability and scholarly productivity, should faculty appointments committees look to other criteria for candidates of color? Provided that we can still consider the race and ethnicity of prospective candidates of color at private institutions, should faculty appointments committees be concerned about how closely identified a candidate is to an essentialized conception, for instance, of Black persons? Should a faculty hiring committee focus its efforts to hire African Americans on a Black person who has ancestral roots in the American South, whose family has endured Jim Crow racism, who is very dark-skinned, whose family background is impoverished, and who grew up in an all-Black segregated environment? Stated conversely, should a faculty appointments committee hire a Black person who does not meet any of these essentialized characteristics? In confronting these issues, this Article calls. into question conceptions of race within mainstream U.S. society and among African Americans and other communities of colo
