The use of therapeutic interventions to reduce crowding-related arousal: A preliminary investigation

Studies of mass transportation crowding have universally shown that such crowding is arousing and often anxiety producing. Attempts to intervene to reduce arousal and anxiety have met with mixed results. In this study four therapeutically based interventions were used to reduce the arousal evoked by a laboratory analogue of mass transportation crowding. Subjects in the intervention conditions showed significantly fewer increases in pulse rate during crowding. Two of the intervention conditions showed significant decreases in skin conductance level when compared to subjects in an uninstructed crowded condition. An intervention which increased feelings of control over the environment resulted in a more positive view of the environment but did not decrease physiological arousal any more than interventions which did not increase perceived control.The research reported in this paper was sponsored by grants from Rutgers University Research Council to Yakov M.

Solving the two-stage cutting stock problem

This paper describes an important class of cutting stock problems not previously discussed in the literature. The problem is one of determining the patterns to be used in a two-stage cutting process with restrictions imposed on the locations of cuts in the first stage. A particularly difficult version of this problem from the plastic film industry is presented and solved.     

The fiducial argument and hacking's principle of irrelevance

In a searching analysis of the fiducial argument Hacking (1965) proposed the Principle of Irrelevance as a condition under which the argument is valid. His statement of the Principle was essentially non-mathematical and this paper presents a mathematical development of the Principle. The relationship with likelihood inference is explored and some of the proposed counter-examples to fiducial theory are considered. It is shown that even with the Principle of Irrelevance examples of non-uniqueness of fiducial distributions exist.

Comic Relief In Everyday Life: Dramaturgic Observations On A Function Of Humor*

The comic relief of the theater has an everyday analog. It is seen in the momentary humorous respites from the seriousness or lengthy concentration on a collective task commonly found in certain spheres of daily life. These respites facilitate the completion of that task by refreshing the participants. Observations of social comic relief made during a series of rehearsals and performances of an amateur theater company are reported. The nature and function of this sort of humor is considered, first in theater, and then in other similar settings. A comparison of social comic relief as a function of humor with selected philosophical and psychological relief theories of humor follows. A concluding section considers the place of creativity and wit in social comic relief.     

Personnel policies and the age structure of an occupation: the case of the academic labor market

Population projection techniques are used to project the size and age structure of the academic labor force. Age specific coverage data from Teachers Insurance and Annuity Association are used to proxy academic employment. Hiring, quit, retirement and death rates are calculated for 1981 and 1982. Projections of the future academic labor force are made holding these rates constant. The results show the importance of these entry and exit rates and also indicate how these rates can fluctuate from year to year.Estimates of the future demand for teachers are used to determine a target rate of growth of the academic labor force. Alternative personnel policies are incorporated into the projections. This analysis indicates that the personnel policies chosen to meet the desired labor force size have substantially different effects on the age structure of the labor force.The authors wish to acknowledge the cooperation of the Teachers Insurance and Annuity Association in providing the data used in this study and specifically Francis King for his assistance and encouragement.
