Validity of the MMPI-2 basic and Harris-Lingoes subscales in a forensic sample.

The present study explored the MMPI-2 correlates of criminal history in a sample of prison inmates. Although Ma was the only basic scale to demonstrate a significant positive association to crime history, three Harris-Lingoes subscales also bore significant associations to this criterion. The Ma1 (amorality), Pd2 (authority problems), and Pd5 (self-alienation) subscales demonstrated positive associations with crime history.

Law, ethical codes, and the report of the CSSP survey on ethics policies. Council of Scientific Society Presidents.

Recently, the Council of Scientific Society Presidents (CSSP) collected data from its member organizations regarding codes of ethics. To better understand why such a survey would be undertaken, this paper begins by examining what is meant by ethics and highlights some distinctions between law and ethics. It then discusses codes of ethics, stressing their purposes and functions.

Relationship marketing of health care plans: retaining corporate customers in a competitive environment.

Corporate employers have become major purchasers of health care. They are gatekeepers who decide whether to retain or drop an insurance company from the choice set offered to employees as well as whether to include new insurers into this choice set. If marketers of health maintenance organizations are to maintain their market share in this competitive environment, they need to understand issues considered important to corporate employers.

Ensuring patient satisfaction in medical groups.

Delivering satisfaction to patients has become increasingly important among professionals in the medical community. However, administrators in medical group practices charged with the task of nurturing customer satisfaction are often required to allocate their limited funds across an array of initiatives intended to ensure the delivery of the right amount and types of services to improve satisfaction among their customers. This requires the ability to locate areas that yield the greatest response per unit of investment.

The implementation of business process reengineering in American and Canadian hospitals.

This study of more than 215 U.S. and Canadian hospital executives indicates that improved service quality to patients and enhanced financial performance are the driving forces for hospitals that undertake business process reengineering (BPR) activities.

Comparative validity of the MMPI-2 Wiener-Harmon subtle-obvious scales in male prison inmates.

The Wiener-Harmon subtle-obvious MMPI subscales (Wiener, 1948; Wiener & Harmon, 1946) have been the subject of considerable debate. In this study, we examined the intercorrelations among full clinical scale T scores and their subtle and obvious subscales in an offender population. Low subtle to full-scale correlations were observed, suggesting that these items contribute little to full-scale scores.

Powerlessness regarding health-service barriers: construction of an instrument.

Purpose: The purpose of the study was to develop a scale to calculate college students' powerlessness regarding health service barriers (PHSB).

Methods: Scale items were generated to represent two domains of interest: powerlessness and college students' powerlessness regarding health service barriers. The final 20-item instrument was subjected to multiple measures of validity with college students and panels of nurse experts in the area of nursing diagnosis.

The Drosophila gene asteroid encodes a novel protein and displays dosage-sensitive interactions with Star and Egfr.

The asteroid gene of Drosophila was found to lie within 189 bp of Star. Asteroid cDNA clones were isolated and sequenced and a single putative open reading frame was identified that encodes a novel protein of 815 amino acids with a calculated molecular mass of 93 kilodaltons. Using cDNA probes, asteroid transcripts were localized to the proliferative tissues of embryos and to the mitotically active tissue anterior to the morphogenetic furrow in eye imaginal discs.

Acetylcholine-activated chloride current in the T-84 colonic cell line.

The stimulation of epithelial chloride secretion by hormones and neurotransmitters involves the activation of apical membrane chloride channels. The regulation of chloride current by acetylcholine in the T-84 colonic cell line was investigated using single-channel patch-clamp techniques. Treatment with carbachol resulted in the stimulation of transient chloride currents in 18 of 32 previously quiescent patches.

Metamemory accuracy: effects of feedback and the stability of individual differences.

This study addressed two questions about metamemory accuracy: how feedback about recall performance affects confidence-recall accuracy and whether individual differences in confidence-recall accuracy are stable across different sets of test items. College students answered general knowledge questions and made confidence ratings about the correctness of the answers. Half the students were told whether their answers were correct.

Correlates of HIV risk appraisal in women.

This study examined the relationship of safer sex behavior practices, knowledge of acquired immunodeficiency syndrome (AIDS), social norms, and familiarity with persons infected with the human immunodeficiency virus (HIV) with HIV risk appraisal in women. Risk appraisal was measured by perceived susceptibility and seriousness of AIDS. The AIDS Risk Reduction Model was used to construct a salient framework for this descriptive, correlational survey in which 208 urban women of mixed ethnicity residing in areas with high rates of sexually transmitted diseases/AIDS participated.

Central implants of dilute estradiol enhance the satiety effect of CCK-8.

The following studies evaluated whether direct placement of estradiol into different brain areas could increase the satiating potency of CCK in female rats. In Experiment 1, estradiol implants in the PVN, but not in the VMN or third ventricle, significantly enhanced the satiety actions of CCK (5.0 micrograms/kg).

Directed case study method for teaching human anatomy and physiology.

A mastery of human anatomy and physiology requires a familiarity with a vast number of details about the human body. A directed method of case analysis is described that helps students deepen and solidify their understanding of anatomical and physiological facts, concepts, and principles. The successful case had four distinctive features as follows: clear learning objectives, a concise and informative scenario, straightforward and didactic questions, and an emphasis on information readily available to the student.

Radicalizing recovery: addiction, spirituality, and politics.

Treatment centers and self-help recovery programs promote individual solutions to substance abuse through changing dysfunctional behavior and relying on spiritual beliefs and practices. The root problems are understood to be diseases within the person. However, the social conditions implicated in causing the addiction remain unaddressed.

Instability of individual differences in the association between confidence judgments and memory performance.

There are large individual differences in the degree of association between the accuracy of memories and subjective confidence in those memories. Are these differences stable within the same test, and between alternate forms of a test? In Experiment 1, college students were tested on 3 recognition memory tasks, then retested 2 weeks later on alternate forms of the same tasks. The relationship between confidence judgments and recognition performance displayed low split-half stability and low alternate-forms stability.

Cognitive styles and personality characteristics strongly influence the decision to have photorefractive keratectomy.

Background: A substantial number of patients who elect to undergo photorefractive keratectomy do so without the motivation of occupational uncorrected vision requirements. We hypothesized that information processing preferences for the auditory (versus visual) modality in a global, associative (versus detailed, sensory-oriented) style with adaptability and risk-taking (versus predictability) personality characteristics would predominate in patients electing photorefractive keratectomy.

Method: Seventy-three prospective photorefractive keratectomy patients attended informational sessions.

Antagonism of estrogenic effects on feeding behavior by central implants of anisomycin.

The following experiment determined whether the estrogenic suppression of food intake is dependent upon changes in protein synthesis within neurons of the paraventricular nucleus of the hypothalamus (PVN). Ovariectomized rats were treated centrally with anisomycin-filled or empty (control) cannulae in the PVN. Females were injected with either 2.

Modulation of the satiety effect of cholecystokinin by estradiol.

Data obtained from a wide variety of mammalian species indicate that feeding behavior can be influenced by changes in endogenous estrogens and by exogenous estrogenic treatments. The present experiment represents an initial investigation of the hypothesis that the suppression of food intake by estradiol is mediated by an enhancement of the satiety effect of cholecystokinin (CCK). Twenty-four female rats were ovariectomized and implanted either with a 5% estradiol silastic capsule or an empty capsule on the day of surgery.

Effects of PVN lesions on the responsiveness of female rats to estradiol.

Previous research has shown that the paraventricular nucleus of the hypothalamus (PVN) is an important site of action for the effects of estradiol on feeding behavior. The recent finding that estrogenic stimulation of the PVN lowers food intake without inducing lordosis suggests that the effects of estradiol on feeding and sexual behaviors are organized separately within the brain. Whether the effects of estradiol on food intake can be attenuated by PVN lesions is therefore a question of practical and theoretical interest.

Changes in ingestive behaviors and body weight following intracranial application of 17 alpha-estradiol.

The present experiment was conducted to determine if central implants of 17 alpha-estradiol could influence food intake, water intake, and body weight in ovariectomized rats. A total of fifteen animals were fitted with bilateral guide cannulae in the paraventricular nucleus (PVN) and stimulated unilaterally with cholesterol and 17 alpha-estradiol in each side of the brain. Compared with cholesterol treatment, 17 alpha-estradiol implants in the PVN significantly lowered food intake and body weight but did not affect water intake.

A molecular dynamics simulation of the (dG)6 . (dC)6 minihelix including counterions and water.

The results of a 60 ps molecular dynamics (MD) simulation of (dG)6.(dC)6 including 10 Na+ counterions and 292 water molecules are presented. All backbone angles and helix parameters for the hexamer are reported in this paper along with trajectory plots of selected angles.

Adolescent drug abuse: problem and prospectus.

Available research indicates that adolescent alcohol and drug abuse is a multi-level phenomenon which seriously affects the functioning of the individual, his (her) interpersonal experiences, the school and society in terms of problem behaviour and other psychopathological and social dysfunctional correlates. Data of the prevalence and problems of abuse obtained by a survey of high school students indicate a high prevalence of alcohol and marijuana used combinationally and heavy users are likely to experience psychopathological consequences, including personal problems of identity diffusion, self-esteem, a motivational syndrome, and acute brain syndrome, interpersonal problems with peers and parents and problems with school participation and the law: adolescents who abuse alcohol and marijuana in combination at the same time are likely to have severe, chronic, and progressive psychopathological problems. Presented is an integrated prospectus for a comprehensive, integrated, longitudinal prevention and intervention program on the community level including components of a holistic information and education programme with a prevention focus; counselling through a student assistance programme of intervention, evaluation and treatment; and rehabilitation through alternative schools.

Effects of intracranial implants of dihydrotestosterone on the reproductive physiology and behavior of male guinea pigs.

An experiment was conducted to determine whether the intracranial application of dihydrotestosterone (DHT), a nonaromatizable androgen, would stimulate male guinea pig mating. Of three castrate groups studied, one was a control group in which subjects were implanted both in the medial preoptic area (MPOA) and under the skin with cannulae containing cholesterol (NoDHT). Males in one of the experimental groups received implants of cholesterol in the MPOA plus subcutaneous implants containing DHT (ScDHT).

Central implants of diluted estradiol: independent effects on ingestive and reproductive behaviors of ovariectomized rats.

The present experiment was undertaken to evaluate the hypothesis that the effects of estrogens on feeding and sexual behaviors are organized separately within the brain. Thirty-three ovariectomized rats were implanted with bilateral guide cannulae aimed at either the paraventricular nucleus (PVN), medial preoptic area (MPOA), or posterior hypothalamus (PH). Subjects that received PVN implants were stimulated with either undiluted estradiol, a 3:1, or 10:1 mixture of cholesterol and estradiol.

Activation of sexual behavior in male rats by combined subcutaneous and intracranial treatments of 5 alpha-dihydrotestosterone.

When given peripherally, 5 alpha-dihydrotestosterone, the major androgenic metabolite of testosterone, is relatively less effective than testosterone in activating sexual behavior of castrated male rats. In order to test the possible central nervous system effects of dihydrotestosterone more directly, we castrated Long-Evans rats, gave them a behaviorally subthreshold dose of dihydrotestosterone placed subcutaneously in Silastic capsules (ScDHT), and then additionally treated the rats with intracranial implants of crystalline dihydrotestosterone (IcDHT, N = 12), testosterone (IcT, N = 12), or cholesterol (IcCHOL, N = 10) placed in the medial preoptic area. The peripheral ScDHT treatment maintained sexual organ weights of castrated males at levels comparable to those of intact males, but did not in itself significantly activate mating behavior.
