Toxic hazard reduction with passive mitigation systems

A major component of the United States Environmental Protection Agency's 112(r) Risk Management Program Rule is the evaluation and control of potential public exposures to toxic chemicals. The rule requires identification and evaluation of a worst case accidental toxic release scenario, but provides for the inclusion of passive mitigation systems in modeling the dispersion hazard zones that are to be communicated to the public. These passive mitigation systems can be taken into account in the consequence modeling if they will withstand the initiating event that causes the accidental release and function as intended. This paper discusses several passive mitigation systems that can be designed as an integral part of storage or processing of highly toxic chemicals. These include, but are not limited to, optimizing storage conditions, design of secondary containment, toxic vapor generation control, and enclosure design. The effectiveness of various passive mitigation systems is evaluated using consequence modeling for case studies involving highly toxic chemicals such as phosgene, chlorine, and ethylene oxide.     

Why do employees keep choosing the high-premium health care plan? An investigation of the financial consequences and logic of employee health care plan selections

In 1991, Dannon employees had the choice to stay with their current health care plan or switch to a new plan which offered a lower premium and less hospital cost coverage that better fit the needs of most employees. Both plans were the same in all other respects. Only 25% of employees chose the new lower-premium plan over the old plan. This article reports a collaborative effort between The Dannon Company and Cornell University's Center for Advanced HR Studies to identify the patterns of employee choices, and the effects of those choices on the actual costs that employees incurred. The actual decisions of 287 Dannon employees were examined, and the out-of-pocket costs that they actually incurred in the two years after the plan was introduced were calculated. © 1996 by John Wiley & Sons, Inc.     

CENTRAL GOVERNMENT BUDGET DEFICITS AND EX ANTE REAL LONG TERM INTEREST RATES IN ITALY: AN EMPIRICAL NOTE FOR 1955-1989

This paper empirically investigates the impact of central government budget deficits upon interest rates in Italy. The period studied runs from 1955 to 1989, and annual data are used. The interest rate measure is the ex ante real rate of interest. It is found, using an instrumental variables technique to control for the endogeneity of the budget deficit, that the budget deficit raises the ex ante real interest rate in Italy.     

Induced Innovation in U.S. Agriculture: Time-series, Direct Econometric, and Nonparametric Tests

The hypothesis of induced innovation is tested for U.S. agriculture using a high-quality state-level panel data set and three disparate testing techniques—time series, direct econometric, and nonparametric. We find little support for the hypothesis. That conclusion is robust across testing techniques. However, as with all empirical tests of this hypothesis conducted to date, ours focus only on the demand side of the hypothesis. The hypothesis could have been rejected simply because the marginal cost of developing and implementing input-saving technologies for the relatively expensive inputs is greater than for the relatively cheap inputs.     

Consuming dark tourism: A Thanatological Perspective

Despite increasing academic attention paid to dark tourism, understanding of the concept remains limited, particularly from a consumption perspective. That is, the literature focuses primarily on the supply of dark tourism; less attention, however, has been paid to the demand for ‘dark’ touristic experiences. This theoretical paper seeks to address this gap in the literature. Drawing upon the contemporary sociology of death, it explores the relationship between socio-cultural perspectives on mortality and the potential of dark tourism as a means of confronting death in modern societies. In so doing, it proposes a model of dark tourism consumption within a thanatological framework as a basis for further theoretical and empirical analysis of dark tourism.     

Is Non-discrimination Really Dead?

‘The most-favored-nation clause in American commercial treaties, as conditionally interpreted and applied by the United States, has probably been the cause in the last century of more diplomatic controversy, more variations in construction, more international ill-feeling, more conflict between international obligations and municipal law and between judicial interpretation and executive practice. more confusion and uncertainty of operation, than have developed under all the unconditional most-favored-nation pledges of all other countries combined’— Jacob Viner, in the Journal of Political Economy (February 1924)
