The adoption rate of building energy standards in the US has been increasing since the mid1990s as a result of the Energy Policy Act of 1992 (EPAct). However, most of the evidence on the energy savings that accrue from commercial building energy standards is based on engineering simulations, which do not account for realized behavior once a standard is actually adopted. This paper uses plausibl...

This study investigates the relationships among pollutant emissions, energy consumption and economic development in China during the period 1982-2007 by using one-step GMM-system model under multivariable panel VAR framework, controlling for capital stock and labor force. Regarding the data for all 28 provinces as a whole, we find that there is a unidirectional positive relationship running fro...

Establishing biological reserves in key habitats is one method of preventing loss of biodiversity. We analyze a dynamic reserve site selection model in which a conservation planner receives a budget each period to purchase sites of heterogeneous cost and ecological value in order to maximize species conserved. Sites chosen as reserved are conserved, while sites left outside the reserve system a...

Toxicity in amyloid diseases is intimately linked to the nature of aggregates, with early oligomeric species believed to be more cytotoxic than later fibrillar aggregates. Yet mechanistic understanding of how aggregating species evolve with time is currently lacking. We have explored the aggregation process of a chimera composed of a globular protein (cellular retinoic acid-binding protein, CRA...

Recent studies consider public R&D spending that affects abatement knowledge and endogenous growth, distortionary taxes that affect physical and human capital formation, pollution taxes that affect environmental degradation, and regeneration that restores natural capital. Our model combines all of those elements. We show how the combination affects results from each prior model, focusing on two...

Elliptocytosis is commonly seen as a hereditary condition. We present a case of myelodysplastic syndrome (MDS) del(q20) variant with concomitant acquired elliptocytosis. A 73-year-old male with a history of prostate cancer presented to the hospital for evaluation of bleeding gums. Initial evaluation showed Hgb of 9.3 gm/dl, hematocrit of 28%, platelet count of 36,000 K/cmm, and WBC of 1.8 K/cmm...

Evidence suggests that a large majority of firms and individuals comply with regulations and tax laws even though the frequency of inspections and audits is often low. Moreover, fines for noncompliance are also typically low when regulatory violations are discovered. These observations are not consistent with static compliance models. Harrington (1988) modified these static models by specifying...

The measurements of the deep-inelastic scattering structure function F2 in HERA 1 have permitted the access to a very interesting kinematical range for testing the theoretical ideas on the behavior of quarks and gluons carrying a very low fraction of momentum of the proton, the so-called small x region. In this limit one expects that non-perturbative effects may give essential contributions. Ho...

The Maryland Water Quality Improvement Act of 1998 (WQIA) seeks to create environmental and other benefits to the Chesapeake Bay through reductions in nonpoint source nutrient pollution. This paper analyzes the economic impacts of the WQIA on agricultural users of nutrients (commercial fertilizers or animal manures) and on poultry growers in the state of Maryland. The net economic impacts to ea...
