Dusk-Dawn Asymmetries in SuperDARN Convection Maps.

The Super Dual Auroral Radar Network (SuperDARN) is a collection of radars built to study ionospheric convection. We use a 7-year archive of SuperDARN convection maps, processed in 3 different ways, to build a statistical understanding of dusk-dawn asymmetries in the convection patterns. We find that the data set processing alone can introduce a bias which manifests itself in dusk-dawn asymmetries.

Resolving Magnetopause Shadowing Using Multimission Measurements of Phase Space Density.

Loss mechanisms act independently or in unison to drive rapid loss of electrons in the radiation belts. Electrons may be lost by precipitation into the Earth's atmosphere, or through the magnetopause into interplanetary space-a process known as magnetopause shadowing. While magnetopause shadowing is known to produce dropouts in electron flux, it is unclear if shadowing continues to remove particles in tandem with electron acceleration processes, limiting the overall flux increase.

Prediction of individual dosage of nortriptyline in depressed elderly outpatients.

Individual daily dosages of nortriptyline (NT) can be predicted from administration of a 50-mg or 100-mg single test dose, with a determination of the plasma level 24 hours later. Because the 50-mg or 100-mg test dose used in previous studies may cause unmanageable acute side effects in elderly patients, a 25-mg NT test dose was used to establish a 24-hour plasma level in 18 physically healthy, moderately depressed, geriatric outpatients. Correlations between the 24-hour test dose plasma level and steady state levels were done for maintenance dosages of 50, 75, and 100 mg/day.

Decreasing the burden in families caring for a relative with a dementing illness. A controlled study.

The purpose of this study was to investigate the efficacy of a specifically designed group support program for relatives of patients with Alzheimer's disease and related disorders. The group program included educational/supportive activities and used basic principles of the cognitive-behavioral approach. Twenty-two subjects participated in an eight-session program.

Use of health care services by older Hispanics.

This paper presents information on regarding older Hispanics' use of health care services in an urban setting. Using the Comprehensive Assessment and Referral Evaluation (CARE) questionnaire, data on patterns of health care use and correlates of health services utilization were collected from a sample of 704 Hispanics age 60 and over residing in Los Angeles County. The results indicate that during the year preceding the interview, 79.

Health needs of the Hispanic elderly.

This paper presents results of a study concerning the health care needs of the Hispanic elderly population of Los Angeles County. By use of the Comprehensive Assessment and Referral Evaluation (CARE) instrument, data on a sample of 704 subjects were employed to compute the scores for 22 Likert-type scales measuring the prevalence of numerous psychiatric, medical, and social problems. The data indicate that older Hispanics were affected by cognitive impairment (13.

Urinary phencyclidine excretion in chronic abusers.

Data on usage patterns of 100 hospitalized chronic phencyclidine abusers was collected. Weekly urine samples were monitored using a new gas chromatographic nitrogen detector analysis for PCP. Abusers were found to be, on the average, young males who had used PCP for approximately 40 months (range 12 to 96 months) and approximately 3 to 4 d/week.

A prospective psychological study of 50 female face-lift patients.

Fifty female face-lift patients were evaluated preoperatively with psychological tests and psychiatric interviews. Their postoperative psychological courses were studied for up to 6 months. Approximately 30% had postoperative depressive reactions.

Patients' requests of an outpatient clinic.

Three-hundred-twenty-five consecutive predominantly lower-class new patients at a psychiatric outpatient clinic rated the importance they attached to each of 14 categories of treatment needs or requests. Psychiatric residents subsequently rated the importance of each request for each patient at the conclusion of their initial assessment interview. Requests reflecting needs for intrapsychic therapy, clarification, and control of feelings were considered very important by approximately two thirds of the patients; needs for institutionalized contact, advice, and community triage by one half; and other requests for medication, reality contact, succorance, ventilation, confession, social intervention, administrative requests by a minority (one fourth to one third).

Personality changes and compatibility in the psychiatric resident--supervisor relationship.

Seventy-one psychiatric resident-supervisor dyads were studied in terms of Schutz's interpersonal theory of compatibility. Personality changes during the second year of psychiatric residency were also measured by means of Schutz's Fundamental Interpersonal Relations Orientation Scale. Predictions relating compatibility to satisfaction with the dyad and to ratings of competence were not confirmed.

Which patients respond to a mental health consumer survey.

Characteristics of patients at the Los Angeles County - University of Southern California Medical Center, Adult Psychiatric Outpatient Clinic who responded to a Los Angeles County voluntary "Client Satisfaction Survey" were compared with those who did not. Three significant differences consistently emerged. If an individual was a member of a minority group (black of Spanish surname), had less than a high school education, and was taking antispsychotic medication, his chance of returning a questionnaire to a waiting-room collection box was 79% as compared to the 30% chance of returning if he had none of these three characteristics.

Patients' attitudes toward behavior therapy and psychotherapy.

A questionnaire survey of 50 patients treated by behavior therapy or short-term, analytically oriented psychotherapy revealed that both groups, as well as those patients who improved the most, placed a high value on insight, the patient-therapist relationship, catharsis, and trust. The findings suggest that behavior therapy patients tend to place more emphasis than do their therapists on factors that have traditionally been thought important in analytic psychotherapy.

Who gets supervised? An extension of patient selection inequity.

A study of 89 individual psychotherapy patients followed by 17 residents in a teaching clinic demonstrated that those presented for supervision significantly differed from the others in being younger, better educated, and better liked by residents and in having higher incomes and longer term treatment. The authors discuss the implications of these findings in relation to the inequity in service time and teaching emphasis that this selection allows.

Truax factors, speech characteristics, and therapeutic outcome.

Initial interview ratings of therapist accurate empathy, unconditional positive regard, and self-congruence were correlated with nonlexical speech characteristics and outcome of individual psychotherapy. Speech characteristics of both patients (greater total speech time, shorter pause time following therapists' comments, and faster reaction times) and therapists (fewer speech units) were significantly related to improved outcome. While Rogers-Truax factors were unrelated to outcome, they were related to speech characteristics of both patient and therapist.

Differences between behavior therapists and psychotherapists.

Patient-therapist interaction patterns of three experienced behavior therapists and three matched analytically oriented therapists were compared. Each therapist saw ten patients in short-term individual therapy. The more active behavior therapists dominated the conversation in terms of speech time, more frequently offered explicit advice and instructions, gave more direct information, presented their own value judgments, and exerted greater control over the content of the interaction than did psychotherapists.

Short-term analytically oriented psychotherapy versus behavior therapy.

Ninety-four outpatients with anxiety neurosis or personality disorder were randomly assigned for four months to a waiting list, behavior therapy, or psychoanalytically oriented therapy. The target symptoms of all three groups improved significantly, but the two treated groups improved equally well and significantly more than those on the waiting list. There were no significant differences among the groups in work or social adjustment; however, the patients who received behavior therapy had a significant overall improvement at four months.
