This research was aimed to evaluate the training program enhancing caring behaviors of new nurses by Kirkpatrick's four level for evaluation model: reaction, learning, behavior, and result of the program. The participants were new nurses, preceptors of new nurses, administrators, patients and members of the patients' family cared by new nurses. The research instruments were: (1) five questionnaires toward program suitability, knowledge, attitude, caring expression, and result to organization. The mean, standard deviation and dependent sample t-test were used for data analysis; (2) guidelines for focus group discussion and semi-structural questionnaire analyzed by content analysis. The study revealed that: (1) the mean of suitability was at the very high level (X = 4.49, SD. = .30); (2) the knowledge and attitude after training were significantly higher than before training at .000 level, [t =-21.65, p = .000 and t = -19.30, p = .000); {3} caring behavior after training was significantly higher than before training at the .000 level; and {4} the result of the program was at the high level { X = 4.25, SD. = .17}, related to the result of semi-structured interview and focus group discussion. These evaluation research finding suggested that administrators can use for improving the preparation of any project and apply to evaluate other training programs, developing human resource system. 展开更多

In Burkina Faso, the Bieha department was purposively selected. The initial rapid rural appraisal was complemented by a household survey. Tools of data collection included observation, key informant interview, and focus group discussion. For the survey, eighty households were selected based on systematic sampling. Data was collected by individual interviews at household level, and for statistical calculations, the households were subsequently categorized as small, medium and commercial based on their homegarden size. It was found that all the surveyed households managed homegardens composed of trees, crops and animals. Majority of the farmers (43%) belonged to the small category due to land constraints. Generally, farms contributed more income than the plant component of homegardens. However, when the livestock component of homegardens was added, homegardens became far more important than farms and accounted for over 60% of income generation for all categories. It can be concluded that homegardens are important to rural people for food and cash income. 展开更多
