Private Schooling in the U.S.: Expenditures, Supply, and Policy Implications
This report provides a first-of-its-kind descriptive summary of private school expenditures. It includes comparisons of expenditures among different types and affiliations of private schools, and it also compares those expenditures with public school expenditures for districts in the same state and labor market. Results indicate that (1) the less-regulated private school sector is more varied in many key features (teacher attributes, pay and school expenditures) than the more highly regulated public schooling sector; (2) these private school variations align and are largely explained by affiliation -- primarily religious affiliation -- alone; and (3) a ranking of school sectors by average spending correlates well with a ranking of those sectors by average standardized test scores
Improved electrical spot terminals
Improved electrical spot terminal has been developed which can be rigidly attached to terminal mounting board. Mounting board is bonded to epoxy board which in turn is bonded to printed circuit board with high temperature adhesive. Conductive lead is coupled between electrical terminal and circuit trace on circuit board. Shape is usually clover-leaf
Electrical spot terminal assembly Patent
Electrical spot terminal assembly for printed circuit board
Pressure transducer
Pressure-sensitive transducer, consisting of a series of spindle-supported electrically conductive metal washers connected to electrical sensing circuitry, determines the force exerted between a mounting bolt and nut on relatively fragile components
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 ..
