近期由天然气涨价的传言所引发的国内部分地区抢购天然气的浪潮，成为了社会关注的一个焦点。本文基于经典的经济学理论，从理性人假设、心理预期、成本收益三个方面对“抢购天然气”现象进行经济学分析，解释了“抢购天然气”的内在经济动力，并在此基础上，探讨了能源价格机制形成的理论基础和实践经验，提出了能源价格形成机制需要注意的四大问题，为能源价格形成机制的进一步改革提供参考依据。

Our paper compares external effects of two municipal solid waste disposal technologies, bioreactor and dry tomb landfills, in a 600-year time- horizon using two different discounting techniques: Constant conventional discounting and Generation Adjusted Discounting (GAD). The paper starts with a short description of the basic characteristics of the two landfill-types. To demonstrate the sustainability deficiencies of constant discounting sustainability gaps are defined and calculated. Reference case for these calculations is the GAD which takes into account the basic requirements of sustainable development, namely inter-generational equity. Our calculations show that constant discounting usually uses too high discount rates to be in accordance with fundamental sustainability criteria leading to biased political suggestions. However, our approach is not solely restricted to landfills. It could be used as a guide to quickly check whether the results of social cost- benefit analyses of long-term public projects are in accordance with fundamental sustainability criteria.

Prescription drugs, a category of psychotherapeutics that comprises prescription-type pain relievers, tranquilizers, stimulants, and sedatives, are among the substances most commonly abused by young people in the United States. Prescription drugs are readily available and can easily be obtained by teenagers who abuse these drugs to experience a variety of desired effects. Often these young people are unaware of the serious health risks involved in abusing prescription drugs. Increasingly younger adolescents obtain prescription drugs from classmates, friends, and family members, or they steal the drugs from school medicine dispensaries and from people for whom the drug had been legitimately prescribed.

This report describes the national municipal solid waste (MSW) stream based on data collected for 1960 through 2009. The historical perspective is useful for establishing trends in types of MSW generated and in the ways it is managed. In this Executive Summary, we briefly describe the methodology used to characterize MSW in the United States and provide the latest facts and figures on MSW generation, recycling, and disposal.

The Arroyo Colorado is an ancient channel of the Rio Grande River that extends eastward for about 90 miles from near the city of Mission, Texas through southern Hidalgo County to the city of Harlingen in Cameron County, eventually discharging into the Laguna Madre near the Cameron- Willacy County line. The tidal segment of the Arroyo Colorado, as classified by the Texas Commission on Environmental Quality (TCEQ), is between the confluence with Laguna Madre in Cameron/Willacy County to a point 100 meters (110 yards) downstream of Cemetery Road, south of Port Harlingen in Cameron County. This part of the river is also defined as a coastal natural resource area (CNRA) and a coastal wetland in the Coastal Coordination Act. Water quality monitoring over the past decade has confirmed low oxygen levels and escalated ammonia and nitrate concentrations that have contributed to multiple fish kills in the tidal segment. These sub-optimal aquatic conditions resulted in this portion of the Arroyo Colorado being placed on the Texas Water Quality Inventory and 303(d) List for high aquatic life use impairment in 2002. Numerous urban sources, such as point source wastewater discharges, have contributed to this impairment; however, according to the Arroyo Colorado Watershed Protection Plan (ACWPP), nonpoint source agricultural runoff accounts for much of the water quality issues in the tidal segment.
