The research report presents results from a study of the amount and intensity of nursing home staff time required to care for patients at various care levels. These levels are defined as light, moderate, and heavy--depending on the time and amount of assistance required to perform various nursing and daily living activities such as mobility and feeding assistance, personal hygiene, skilled procedures, and special skin care. Work sampling and time and motion studies for registered nurses, nurses' aides, and licensed vocational nurses showed that heavy-care patients required over 2.5 times the amount of staff effort required for light-care patients. It was true regardless of the manner in which the activity times were assigned. The report also compares these results from a demonstration in California with those of three earlier studies in Maryland, Ohio, and West Virginia. The study, part of a larger demonstration project on reimbursement incentives for nursing homes, was sponsored by the National Center for Health Services Research and Health Care Technology Assessment and conducted in 36 proprietary skilled nursing facilities over a 30-month period beginning in November 1980.

The objective of this study is to establish accurate repair time standards for transit vehicles in Florida public transit systems. This project develops standards in order to minimize the time required to perform tasks, continually improve reliability of services and to conserve resources and minimum costs by specifying direct/indirect materials of tools to provide repair service. This report has been organized as follows: Section two describes the brake system and the processes involved in completing a brake job. In section three the Time Study method is described and considerations while conducting the Time Study are provided. How the standards were established is described in section four. The database development and its description are presented in section five. Finally, recommendations and conclusions drawn from the research and a look into future possibilities for the Transit Sector are given in section six.

The present experiments were conducted to study response programming in handwriting tasks. Twelve right-handed subjects wrote acoustically presented words and short sentences which were digitally recorded. Changes in latency, movement time, trajectory distance and pen pressure were studied as a function of response complexity (i.e., word length, spacing distance, and initial letter). A lengthening of the spatiotemporal parameters preceding the more complex structures reflects effects of mental load. The results also indicate that the choice of a programming strategy can be dependent on the complexity structure of the task. Writing pressure decreased as a function of increasing letter sequence length. The findings support a hierarchical model of handwriting.

Tritiated saxitoxinol was used to obtain preliminary information on saxitoxinmetabolism in the rat. Sublethal doses of tritiated saxitoxinol (18.9-micro Ci/kg; 3.8 micrograms/kg) were injected i.v. into each of six rats. Urine and fecal samples were collected up to 144 hr post-injection. Within 4 hr, 60% of injected radioactivity was excreted in urine. No radioactivity was found in feces. High performance liquid chromatography analyses of urine showed that saxitoxinol was not metabolized by the rats.

This study investigates the feasibility of quantifying terminal area delay from the measurement of departure and arrival elapsed times. Elapsed time data were obtained on all fixed wing itinerant flights occurring at Philadelphia International Airport, Philadelphia, Pa., and Byrd Field, Richmond, Va., during a 10 day period in May. The report describes the behavior of the elapsed time data obtained, discusses the use of elapsed time data as a measure of NAS terminal performance, and makes some recommendations regarding the initiation of a national terminal performance measurement system.

The determination of time by east and west observation of the zenith distance of a star near the prime vertical shows discrepancies as much as 2 seconds of time. A new method with higher accuracy has been developed. It is based on observation of an individual pair of stars. The observation of each star (one east, the other west of the meridian) consists of determining the instant of time at which it crosses a fixed preselected unknown zenith in order to determine the circumstances when greatest accuracy can be expected.

In an extensive ocean test known as the Medium Stability Experiment conducted at the Atlantic Undersea Test and Evaluation Center,rms linearly detrended fluctuations of acoustic pathlength were found to be of the order of lambda/100at 10kHz over a 1-minute period. Pathlength stability was deduced from precise measurements of acoustic travel time over a 2500-meter path extending from a 70-meter depth to the bottom of the ocean. A state-of-the-art inertial measurement unit was used to compensate the travel time for motion of the acoustic projector. The report details the analysis used to remove errors in motion compensation from the travel time data order to obtain a measure of the acoustic pathlength stability. (Author)

Advances (left shifting) and delays (right shifting) are shown to be inverses for the Laplace and z-transforms. This is true for both bilateral and unilateral Laplace and z-transforms. This result is not in agreement with some literature on these subjects, and the oversight made in that literature is pointed out. (Author)
