Representation of racial minority students in selected Canadian university schools of nursing

Several studies have suggested that the problem of inequality in educational opportunity for minority students, manifested by under-representation, prevails in American higher education. Under-representation of minority groups in schools of nursing is not an unusual problem. The dearth of information on representation of ethnic minorities in baccalaureate programmes in Canada provided the impetus for the investigators to conduct this study to: (1) explore the racial and ethnic composition of the student population in selected Canadian University Schools of Nursing; (2) determine the total number of withdrawals and graduations; and (3) establish baseline data for a follow-up study. This study was exploratory in nature. A questionnaire was designed to elicit information on enrollment, admission, withdrawal and graduation of six ethnic minority groups in the 5 year period, 1974-1978. Out of 18 schools surveyed, nine schools responded with the requested statistical information. Findings of this study supported findings of other research studies conducted in the United States in that the ethnic minorities were under-represented, and their academic survival rates were low. Statistics presented in this study should not be interpreted as conclusive. Many questions crucial to exploring and understanding the pattern of representation of racial and ethnic minority nursing students are still unanswered. A better designed, long-term study is needed.

The use of acupuncture in ophthalmology

The object of this study is to answer the question: Is acupuncture of any use in ophthalmology? Ophthalmology today can boast of 95% accuracy in diagnosis, but modern therapeutics has not caught up with diagnosis. Despite an inability to explain in modern scientific terms the healing power of acupuncture, documentation of over 500 cases treated shows that this modality can be successful in the treatment of eye diseases, especially in cases of retinitis pigmentosa, high myopia, cataracts, surgical aphakia, controlled glaucoma and re-attached ablation retinae. We notice in these cases that improvement occurs in the central acuity, and no improvement in the visual field, colorvision and nightblindness. Apparently acupuncture acts on the macula alone and not on the entire retina. Acupuncture is not intended to substitute for established medication or surgery in ophthalmology. It cannot restore a tissue or organ damaged beyond regeneration; "incurable" eye diseases per se are not cured by acupuncture. Only symptoms are relieved and dimness of vision is a symptom which can be alleviated in many cases with periodic treatment.

Scleral and choroidal calcifications in a patient with pseudohypoparathyroidism

This case report suggests that calcifications in the sclera and choroid may be a feature of pseudohypoparathyroidism and shows a calcium distribution more extensive and severe than that characteristically seen in other metabolic conditions associated with calcium deposits in the eye. Ocular ectopic calcification is a part of the more generalised ectopic soft tissue calcification seen with pseudohypoparathyroidism. Evaluation of the contribution of the terminal renal failure and uraemia to the ectopic ocular calcification would require sequential evaluation of eyes with pseudohypoparathyroidism, but without the added complication of uraemia.

Nurse--teacher behaviours in the clinical field: apparent effect on nursing students' learning

One primary source of feedback on the effectiveness of their teaching, which instructors may easily overlook, comprises of students' reactions. The purpose of this study is to identify students' perceptions of teacher behaviours, which either facilitate or hinder students' learning in the clinical field, and to determine if there is a difference in the perceptions of 1st and 2nd year students. This study is exploratory and descriptive in nature. Firstly, some research studies regarding effective clinical teaching in nursing are reviewed, followed by a discussion of the research design. The tool used for collecting data is a modified form of the critical incident technique. A description of illustrative incidents is requested within five divisions: professional competency, relationship, personal attributes, teaching methods, and evaluation of practice. A system for analysis and coding of data is then discussed. Finally, the finding of this study is presented. It would seem ot the investigator that students in 1st year are particularly sensitive to how the teacher makes them feel, whereas students in the 2nd year would seem to be more concerned with the teacher's competency in teaching. The teacher behaviours reported as helpful or hindering to students' learning, as identified by the students, are outlined.

Purification and properties of choriogonadotropin from human term placenta

Affinity chromatography has been applied successfully to the isolation of human choriogonadotropin from human term placenta. In a single step, a 57-fold purification was achieved. Evidence is presented which indicates that the product contains intact hormone as well as its free alpha-subunit. Preliminary data suggest that a variant form of alpha-subunit is also present which has serine as its N-terminal and contains relatively little arginine and proline as compared to the authentic alpha-subunit.

Quantitative microscopy of epidermoid lung carcinoma: correlation with survival time

Quantitative microscopy, including morphometry of tumor, stroma, and necrosis was used for the prognostication of pulmonary carcinoma. This was supplemented by the mitosis: necrobiosis ratio, reciprocal of cell count, and number of "apoptosis" bodies. Data for 15 short-term (4-19 mo) and 8 long-term (32-132 mo) survivors with epidermoid carcinoma were expressed as indexes. The morphometric index averaged 106.8 for short-term and 156.1 for long-term survivors, respectively. Addition of the other three indexes resulted in an average of 171.4 for short-term and 318.5 for long-term survivors. Morphometric index and the necrobiosis: mitosis ratio were of greater significance than the other two indexes. Discriminatory function analysis based on the weighted sum of the logarithms of the four indexes demonstrated their usefulness in classifying patients as short-term or long-term survivors. The error rate for the discriminant analysis was 3.5%.

Vision analysis and refractive status of youths in a juvenile detention home population

Clinical optometric findings of 633 juvenile dentention youths were statistically evaluated and compared to data from the general population. The youths had a higher referral rate of refractive errors, organic problems, and muscle in balances than the general population. Female youths exhibited a higher incidence and greater severity of myopia than males at all ages. Referral rate for astigmatism among the youths was higher than the general population although the dioptric power was in agreement with previous studies.

Operant approaches to group therapy in a school for handicapped children

In order to determine the effectiveness of operant approaches to group therapy with children with cerebral palsy or mental retardation, four boys aged between 4 years 10 months and 5 years 7 months were given a total of 23 twice-weekly 30-minute treatment sessions. After treatment there was considerably improvement in the children's attention-to-tasks and they showed some increase in social interactions, though to a lesser degree. Teacher ratings also showed some improvement in classroom behavior.

Menstrual cycle and contraceptive hormonal effects on temporal discrimination

2 groups of normal females, one group receiving synthetic oestrogen and progestogen preparations, were tested for the discrimination of temporally paired flashes on 5 occasions corresponding to standard points on the menstrual cycle. The discrimination scores were subjected to a signal-detection analysis. The results indicated lower sensory sensitivity scores for the medicated group which also failed to show the cyclical changes evidenced by the nonmedicated Ss. It is suggested that the cyclical changes paralleled the hypothetical changes in endogenous oestrogen and progesterone secretion which are nullified by the synthetic hormones.
