Economic Injustice and the Rhetoric of the American Dream explores public conversations about why some Americans are rich and others are poor. That question prompts a politically urgent and intellectually valuable inquiry into the rhetorical resources Americans employ to make sense of their peculiar economic arrangements.

Neoliberalism is an anti-democratic ideology. It takes decisions about the allocation of scarce resources out of the hands of public institutions and places them in the hands of private actors. Despite a distrust of democratic institutions immanent to neoliberalism, its reach within those same institutions reveals potent ideological lessons. Even the courts, ostensibly a bulwark against anti-democratic impulses, have incorporated neoliberal arguments into their rulings. As the courts have adopted neoliberal discourse they have reimagined society as a market populated by consumers. Accordingly, in this article we examine five Supreme Court rulings that illuminate how the publicly interested citizen is replaced by the self-interested consumer as the basic unit of democracy. We argue these rulings rhetorically predispose voters to think of social problems in the neoliberal language of privatization and profit through three themes: (1) elevating the market, (2) expanding the market, and (3) advertising the market. Broader implications are discussed including a more comprehensive explanation for how neoliberal judicial discourse has played a vital role in orienting the public to accept policies designed to concentrate public resources and decisions into the hands of private actors.

The General Lake Model (GLM) is a one-dimensional open-source code designed to simulate the hydrodynamics of lakes, reservoirs, and wetlands. GLM was developed to support the science needs of the Global Lake Ecological Observatory Network (GLEON), a network of researchers using sensors to understand lake functioning and address questions about how lakes around the world respond to climate and land use change. The scale and diversity of lake types, locations, and sizes, and the expanding observational datasets created the need for a robust community model of lake dynamics with sufficient flexibility to accommodate a range of scientific and management questions relevant to the GLEON community. This paper summarizes the scientific basis and numerical implementation of the model algorithms, including details of sub-models that simulate surface heat exchange and ice cover dynamics, vertical mixing, and inflow-outflow dynamics. We demonstrate the suitability of the model for different lake types that vary substantially in their morphology, hydrology, and climatic conditions. GLM supports a dynamic coupling with biogeochemical and ecological modelling libraries for integrated simulations of water quality and ecosystem health, and options for integration with other environmental models are outlined. Finally, we discuss utilities for the analysis of model outputs and uncertainty assessments, model operation within a distributed cloud-computing environment, and as a tool to support the learning of network participants. © 2019 Author(s). ; Acknowledgements. The primary code for GLM has been developed by Matthew R. Hipsey, Louise C. Bruce, Casper Boon, Brendan Busch, and David P. Hamilton at the University of Western Australia in collaboration with researchers participating in GLEON, with support provided by a National Science Foundation (NSF) (USA) Research Coordination Network Award. Whilst GLM is a new code, it is based on the large body of historical research and publications produced by the Centre for Water Research at the University of Western Australia, which we acknowledge for the inspiration, development, and testing of several of the model approaches that have been adopted. Funding for the initial development of the GLM code was from the U.S. NSF Cyber-enabled Discovery and Innovation grant awarded to Paul C. Hanson (lead investigator) and colleagues from 20092014 (NSF CDI-0941510); subsequent development was supported by the Australian Research Council projects awarded to Matthew R. Hipsey and colleagues (ARC projects LP0990428, LP130100756, and DP130104078). Funding for the optimization and improvement of the snow and ice model was provided by NSF MSB-1638704. Funding for the development of the GLM teaching module and GRAPLEr was provided by NSF ACI-1234983 and NSF EF-1702506 awarded to Cayelan C. Carey.

The modelling community has identified challenges for the integration and assessment of lake models due to the diversity of modelling approaches and lakes. In this study, we develop and assess a one-dimensional lake model and apply it to 32 lakes from a global observatory network. The data set included lakes over broad ranges in latitude, climatic zones, size, residence time, mixing regime and trophic level. Model performance was evaluated using several error assessment metrics, and a sensitivity analysis was conducted for nine parameters that governed the surface heat exchange and mixing efficiency. There was low correlation between input data uncertainty and model performance and predictions of temperature were less sensitive to model parameters than prediction of thermocline depth and Schmidt stability. The study provides guidance to where the general model approach and associated assumptions work, and cases where adjustments to model parameterisations and/or structure are required.
