A field study report of intensive computer keyboard training with schoolchildren.

A video-based keyboard skills training programme was used to teach primary and secondary school students to touch type, in ten 45-min lessons. Previous research (Glencross and Bluhm, 1986) had found the programme to be successful in training a variety of personnel in the workforce. In all, 197 students (105 females, 92 males) received instruction over a two-week period. The influence of age (11-12, 13-14, 15-16, 17-18 years) and sex on keyboard operating speed and accuracy were examined. Speed tests were conducted after the second and ninth lesson. Significant improvements in speed of typing were recorded for all age categories. Age and sex were found to be associated with speed of typing and rate of improvement across tests. Error rates remained constant across tests.

Iron and infection in infancy--report on field studies in Papua New Guinea: 1. Demographic description and pilot surveys.

Madang district was selected for a longitudinal study of the effects of iron prophylaxis on infectious morbidity in infancy and the topography, climate, domicile, ethnology, demography, disease patterns, nutrition and health services of the district are described. The area has a tropical, humid climate and a mixed economy. Pneumonia was the main killing disease at all ages, and malaria was endemic. A base hospital and well organized maternal and child health services ensured that morbidity surveillance would be optimal. Pilot haematological surveys confirmed a high incidence of anaemia in infancy. Mean haemoglobin between nine and 52 weeks of age was 8.6 g/dl. Results suggested that malaria and iron deficiency were important causes of this anaemia.

Iron and infection in infancy--report on field studies in Papua New Guinea: II. Protocol and description of study cohort.

The protocol for a prospective, randomized, double-blind, placebo controlled trial of iron prophylaxis in infants is described. Specific design points discussed include (i) control and "blind", (ii) dose, preparation and age of administration of iron, (iii) standardization of morbidity recording, (iv) data analysis and (v) ethics. The study cohort at birth is described and rationale for exclusions and reasons for withdrawals are discussed. An initial descriptive comparison is made of treatment and control groups entering the trial at two months of age.

Short report: assessing field vaccine efficacy for measles in famine-affected rural Ethiopia.

Measles is a major cause of mortality in complex emergencies. Both high vaccination coverage and vaccine efficacy are required to prevent major epidemics of measles in such situations. Evaluation of field vaccine efficacy is a critical but underutilized component of program monitoring in emergencies, and is particularly important in rural areas where the integrity of the cold chain is difficult to guarantee. In July 2000, we evaluated the field vaccine efficacy for measles vaccination by comparing the incidence of cases in vaccinated and unvaccinated groups during a two-stage cluster survey of 563 children in Ethiopia. Approximately 30% of the measles cases occurred in vaccinated children. Estimated field vaccine efficacy for measles was 66.9% in children 9-36 months old. The finding of a field vaccine efficacy for measles less than 80% warrants formal assessment of measles vaccine efficacy, particularly in famine emergencies where measles is associated with a high case fatality rate.

Nursing outcomes classification: a preliminary report of field testing.

Clinically useful and measurable patient outcomes that are sensitive to nursing interventions are needed to determine the effectiveness of nursing care. Nursing Outcomes Classification (NOC) researchers are evaluating the reliability, validity, and usefulness of the first 190 published outcomes in 10 sites representing the continuum of care. Preliminary analysis of inter-rater reliability and construct or criterion validity of 15 outcomes are described. Results indicate NOC outcomes can be used to accurately document the effectiveness of nursing interventions.

Poliomyelitis vaccine; a report on field trials in Southern Alameda County in 1954.

Southern Alameda County was the only area in California to take part in the 1954 nationwide field trials for testing poliomyelitis vaccine. Besides the contribution made in evaluating the vaccine, other benefits were:1. Participation contributed to the control of a serious communicable disease.2. Inoculations of vaccine during the field trials in all probability prevented some cases of paralytic poliomyelitis among children in southern Alameda County.3. The community became better informed about poliomyelitis and more interested in the local health department.4. Local physicians had an opportunity to contribute to important research and to give a valuable community service.5. The staff of the Alameda County Health Department became better informed and better prepared for any future responsibilities in poliomyelitis immunization programs.Other conclusions reached as a result of participation in the 1954 field trials are that the initial planning of the study was hasty and not sufficiently representative of medical and administrative thinking. If the trials had been planned for 1955 instead of 1954 there would have been sufficient time for research to be completed, professional information to be assured and for sound design of study.
