C & A Carbone v. Clarkstown: A Wake-Up Call for the Dormant Commerce Clause
Introduction Garbage collection, transportation, and disposal have historically been the responsibility of individual towns and cities in the United States. 1 However, stringent environmental regulations, declining landfill capacity, and the implementation of costly source reduction and recycling programs have greatly increased the costs of waste management borne by towns. 2 For the past two decades, many local governments have relied on flow control ordinances to finance their solid waste management activities. 3 These ordinances designate where municipal solid waste generated within the community must be managed, stored, or disposed. 4 Recently, in C & A Carbone, Inc. v. Town of Clarkstown, 5 the U.S. Supreme Court ruled that such ordinances violate the Commerce Clause of the U.S. Constitution. In this decision, the Court misapplied the dormant Commerce Clause doctrine and thereby jeopardized the financial stability of local governments that have relied on flow control ordinances to finance their waste management programs. Flow control ordinances dictate where a community\u27s garbage must be processed or disposed. 6 By enabling a local government to control its garbage, flow control helps the town meet its environmental goals, such as ensuring that recyclable materials are properly separated. 7 Typically, garbage processing and disposal facilities charge a fee per ton of garbage handled, known as a tipping fee. 8 By requiring all municipal waste to be shipped to a designated facility, flow control guarantees a stream of revenue to that facility. 9 Local governments have relied on this revenue to fund ..
Spectral C*-categories and Fell bundles with path-lifting
Following Crane's suggestion that categorification should be of fundamental
importance in quantising gravity, we show that finite dimensional even
-real spectral triples over \bbc are already nothing more than full
C*-categories together with a self-adjoint section of their domain and range
maps, while the latter are equivalent to unital saturated Fell bundles over
pair groupoids equipped with a path-lifting operator given by a normaliser.
Interpretations can be made in the direction of quantum Higgs gravity. These
geometries are automatically quantum geometries and we reconstruct the
classical limit, that is, general relativity on a Riemannian spin manifold.Comment: 20 pages, 1 figur

A Case of Hyperkalemia Versus Pseudohyperkalemia in Chronic Lymphocytic Leukemia
Introduction: Both hyperkalemia and pseudohyperkalemia occur in the emergency department. True hyperkalemia necessitates emergent treatment while pseudohyperkalemia requires recognition to prevent inappropriate treatment. It is imperative that the emergency physician (EP) have an understanding of the causes and clinical presentations of both phenomena.Case Report: We present a case of an 88-year-old male with chronic lymphocytic leukemia (CLL) and suspected blast crisis who was found to have elevated serum potassium levels without other manifestations of hyperkalemia and eventually was determined to have pseudohyperkalemia due to white cell fragility.Discussion: Differentiation of hyperkalemia and pseudohyperkalemia is a critical skill for the EP. We discuss multiple causes of hyperkalemia and pseudohyperkalemia in an effort to broaden the knowledge base.Conclusion: We present a case of CLL as an unusual cause of pseudohyperkalemia and review common causes of pseudohyperkalemia
Interpretation at the controller's edge: designing graphical user interfaces for the digital publication of the excavations at Gabii (Italy)
This paper discusses the authors’ approach to designing an interface for the Gabii Project’s digital volumes that attempts to fuse elements of traditional synthetic publications and site reports with rich digital datasets. Archaeology, and classical archaeology in particular, has long engaged with questions of the formation and lived experience of towns and cities. Such studies might draw on evidence of local topography, the arrangement of the built environment, and the placement of architectural details, monuments and inscriptions (e.g. Johnson and Millett 2012). Fundamental to the continued development of these studies is the growing body of evidence emerging from new excavations. Digital techniques for recording evidence “on the ground,” notably SFM (structure from motion aka close range photogrammetry) for the creation of detailed 3D models and for scene-level modeling in 3D have advanced rapidly in recent years. These parallel developments have opened the door for approaches to the study of the creation and experience of urban space driven by a combination of scene-level reconstruction models (van Roode et al. 2012, Paliou et al. 2011, Paliou 2013) explicitly combined with detailed SFM or scanning based 3D models representing stratigraphic evidence. It is essential to understand the subtle but crucial impact of the design of the user interface on the interpretation of these models. In this paper we focus on the impact of design choices for the user interface, and make connections between design choices and the broader discourse in archaeological theory surrounding the practice of the creation and consumption of archaeological knowledge. As a case in point we take the prototype interface being developed within the Gabii Project for the publication of the Tincu House. In discussing our own evolving practices in engagement with the archaeological record created at Gabii, we highlight some of the challenges of undertaking theoretically-situated user interface design, and their implications for the publication and study of archaeological materials
