Motivations for pleasure vacation

Crompton, John L., “Motivations for Pleasure Vacations,” Annals of Tourism Research, October/December 1979, VI(4):408–424. The study is concerned with identifying those motives of pleasure vacationers which influence the selection of a destination. It also seeks to develop a conceptual framework capable of encompassing such motives. Empirically nine motives were identified. Seven were classified as socio-psychological, namely: escape from a perceived mundane environment, exploration and evaluation of self, relaxation, prestige, regression, enhancement of kinship relationships, and facilitation of social interaction. The two remaining motives, novelty and education, formed the alternate cultural category. The latter were noted to be at least partially aroused by the particular qualities that a destination offered. By contrast socio-psychological motives were found to be unrelated to destination attributes. Here the emphasis shifted from the destination itself to its function as a medium through which socio-pschological needs could be satisfied. The research data suggest that the tourist industry may usefully pay greater attention to socio-psychological motives in developing product and promotion strategies.

Structured packings for use in oxygen service: Flammability considerations

Metallic structured packings have found increasing use in the cryogenic distillation of air. An experimental program was performed to test the flammability of selected metal packings under simulated high oxygen concentration operating conditions. Aluminum flammability in gaseous oxygen has been shown to be very dependent upon argon dilution, and in the presence of liquid oxygen, strong energy releases have been observed. Brass packing exhibited an unexpectedly high relative flammability whereas copper has been found to be non-flammable in all tested oxygen purities. These findings suggest the use of copper structured packing in higher purity GOX/LOX regions of an air separation distillation column and aluminum structured packing in the remainder of the column.     

Performance of aqueous hazmat foams on selected hazardous materials

This exploratory research program represents a continuing commitment that was undertaken to provide, where possible, some solution to vapor control problems through the use of special foams, equipment and technical information.     

Correlation of acid gas-ethanolamine equilibrium using ionic concentrations

Experimental equilibrium measurements are modeled using a Davies-like ionic strength correction term for the reaction equilibrium constants. Calculated and experimental results are in much better agreement when the ionic strength correction terms are used.     

EFFECTS OF PRICE AND AVAILABILITY ON ABORTION DEMAND

Over 1.5 million legal abortions were performed in the United States in 1988. State-level regulation affecting the price or availability of abortion services may expand given recent Supreme Court decisions. This paper uses state-level data pooled over time to estimate abortion demand. Using single cross-sections of state data, past studies find abortion demand per 1,000 pregnancies to be price inelastic and find income elasticity to be positive and significant. The analysis here shows that price elasticity estimates in a single cross-section are sensitive to the choice of state characteristics used to control for "abortion attitudes" within a state. Ajixed-efects model design with pooled data gives more robust abortion demand price elasticity estimates. The results suggest that any new state regulations that increase the costs of obtaining abortions will reduce abortion use and increase unintended fertility .
