Case commentary--Bass v. Barksdale: implications for public health and home care nurses.

A recent malpractice case involved public health nurses. Given the legal issues based on this case, recommendations can be made to help ensure legal accountability, improve practice, and minimize liability risk. Areas of concern include doctor's orders and communication relating to telephone orders, the nurse's accountability to the client, documentation and patient teaching, the physician's duty to supervise the nurse, and corporate negligence.

Learning style research: a critical review of the literature and implications for nursing education.

Much has been written about the implications of learning styles on the teaching/learning process. As a result, several articles related to learning styles can be found in the nursing literature. Although learning styles is one factor that should be considered when planning teaching strategies, its impact may be overrated.

AIDS education on the college campus: Roy's adaptation model directs inquiry.

We assessed the beliefs of 49 college students regarding the acquired immunodeficiency syndrome (AIDS), condom use, and sexual behaviors related to AIDS prevention. Roy's modes of self-concept, interdependence, and role function were used as a framework to find psychosocial determinants that influence safer sex practices. Interdependence was measured by a sexual regard scale.

Choice with delayed and probabilistic reinforcers: effects of variability, time between trials, and conditioned reinforcers.

In a discrete-trials procedure with pigeons, a response on a green key led to a 4-s delay (during which green houselights were lit) and then a reinforcer might or might not be delivered. A response on a red key led to a delay of adjustable duration (during which red houselights were lit) and then a certain reinforcer. The delay was adjusted so as to estimate an indifference point--a duration for which the two alternatives were equally preferred.

Choice behavior in transition: development of preference with ratio and interval schedules.

In Experiment 1, the choice responses of 8 pigeons were observed during 50 periods of transition. Each condition began with equal probabilities of reinforcement on 2 response keys and switched to unequal probabilities. With the ratio of the 2 probabilities held constant, preference for the higher probability developed more rapidly when the 2 probabilities were high than when they were low.

Computer-assisted tracking simulation (CATS).

The tracking technique involves a sender reading consecutive segments from a story and a receiver attempting to repeat each segment verbatim. The reliability and validity of the tracking procedure have been criticized based upon uncontrolled variables such as sender, receiver, and text characteristics. To address these problems, a computer-assisted interactive tracking simulation (CATS) system has been developed in which story segments are presented to the receiver via a video laser disc system and repair strategies are implemented through a computer program.

Extending health care to AFDC recipients who obtain jobs: results of a demonstration.

This study investigated the outcomes of a demonstration project that provided free medical coverage to former Aid to Families with Dependent Children (AFDC) recipients who were holding jobs with limited or no health benefits. Data were collected on the Medicaid expenditures of 54 eligible participants and their dependents for up to two years before they exited welfare; the expenditures averaged 56 percent less for adults and 45 percent less for children than the respective AFDC averages for the county. Because only 22 percent of the eligible participants took advantage of the program, telephone interviews also were conducted with 24 people who did not participate in or dropped out of the health plan.

Classification of ultrasonic image texture by statistical discriminant analysis of neutral networks.

In this paper the ability of two common statistical discriminant analysis procedures are compared with two commercial neural network software packages. The major objective of this study was to determine which of the procedures could best discriminate between normal and abnormal ultrasonic liver textures. The same set of features were input into both statistical discriminant analysis procedures and both neural network models.

Choice with probabilistic reinforcement: effects of delay and conditioned reinforcers.

Two experiments measured pigeons' choices between probabilistic reinforcers and certain but delayed reinforcers. In Experiment 1, a peck on a red key led to a 5-s delay and then a possible reinforcer (with a probability of .2).

Choice behavior in transition: development of preference for the higher probability of reinforcement.

Ten acquisition curves were obtained from each of 4 pigeons in a two-choice discrete-trial procedure. In each of these 10 conditions, the two response keys initially had equal probabilities of reinforcement, and subjects' choice responses were about equally divided between the two keys. Then the reinforcement probabilities were changed so that one key had a higher probability of reinforcement (the left key in half of the conditions and the right key in the other half), and in nearly every case the subjects developed a preference for this key.

Preliminary study of effect of decision making on locus of control among prison inmates.

To study the effect of teaching decision-making to inmates in a maximum security facility on locus of control 19 adult male inmates who were incarcerated at a community correctional center were pre- and posttested on the Rotter Internal-External Locus of Control Scale. In this preliminary study there was no statistically significant difference at pretest or posttest so teaching decision-making skills in group settings versus teaching in a group combined and one-to-one contact did not affect locus of control as measured. This personality trait appears stable over time and a more thorough means of intervention is required to effect change.

Choice between delayed reinforcers and fixed-ratio schedules requiring forceful responding.

This experiment measured pigeons' choices between delayed reinforcers and fixed-ratio schedules in which a force of approximately 0.48 N was needed to operate the response key. In ratio-delay conditions, subjects chose between a fixed-ratio schedule and an adjusting delay.

Theories of probabilistic reinforcement.

In three experiments, pigeons chose between two alternatives that differed in the probability of reinforcement and the delay to reinforcement. A peck at a red key led to a delay of 5 s and then a possible reinforcer. A peck at a green key led to an adjusting delay and then a certain reinforcer.

High-technology and hospice home care. Strange bedfellows.

Technologic advances are changing hospice home care. A case study explores the clinical dilemmas and illustrates the educational and research agendas required to resolve them.

Psychotherapy and religion: The emmanuel movement.

This paper reconsiders the significance of the Emmanuel movement, a pre- Freudian psychotherapeutic system founded by Dr. Elwood Worcester as a method of church-sponsored healing. Its significance lies in three areas: (1) Historically, it was a popular effort by Protestant clergy to claim religious authority over psychological and psychosomatic ailments, a struggle that the medical profession eventually won almost completely.
