ABSTRACT: Decades of research have provided evidence that food irradiation is a safe technology that can decrease the incidence of foodborne diseases; however, adoption of this technology has been slow. The purpose of our study was to qualitatively explore the effectiveness of various components of a professional development training on family and consumer sciences county extension educators' understanding of food irradiation. This training included presentations by experts in the field, a tour of a food irradiation research facility and a meat processing facility, group activities, and a computer simulation model. Data were collected using qualitative research methodology through in-depth interviews conducted after the training. Results indicated that those components that allowed participants to visualize food irradiation processes seemed most beneficial to their understanding. Based on these data, implications for practice are discussed. 相似文献

Some conclusions This study has demonstrated the feasibility of improving the laboratory performance of freshman chemistry students through
planned skill practice activities. However, no differences were found among the specific practice strategies which were employed.
Mental practice of laboratory techniques represents the most efficient strategy in terms of the necessary laboratory resources.
Although mental practice alone was not expected to be as effective as physical practice, this study’s findings proved to be
an exception to the implications of earlier reported literature. However, if one accepts the argument that prior experience
with the appropriate apparatus during the pretest experiment and/or high school courses was significant, then this study is
consistent with the implications of the proposed model. Thus mental practice, to be fully effective, should be associated
with prior experience of the task.
Evaluation of such findings should relate to the degree of improvement which was found relative to the investment of student
time and laboratory resources in the practice activities. A more detailed discussion of the study is provided elsewhere (Beasley,
1978). 相似文献

This paper deals with the development of a paediatric team approach to the care of children in the 70 bed paediatric unit in the Royal Hobart Hospital in Tasmania, Australia, and describes the measures used to help children and their parents adapt to life in hospital with a limited budget. The staff includes paediatricians and pediatric surgeon, resident staff, nurses, teachers, social worker, physiotherapist and pharmacist. There are no visiting hours but the wards are open to parents and relatives at any time. Parents are encouraged to stay in hospital and their accommodation is either in flats at the end of wards or in single or double bed wards using foldup beds. Each young child has a personal details form completed and placed on the end of the cot allowing a nurse to discover likes, dislikes, methods of feeding and sleeping, etc. Parents are asked to complete questionnaires at the time of the child's discharge, asking for their assessment of the standards of care their child received. Playleaders are rostered for evenings and weekends and they work with, and direct Red Cross volunteer ladies. Two full-time teachers cooperate with the child's school in maintaining the child's educational progress. Volunteer visitors entertain children whose relatives are unable to visit or stay in hospital. The methods used to raise the standards of paediatric nursing are also described. Community groups, particularly kindergarten and primary school children, are encouraged to visit the paediatric unit and each group is usually given a brief health education talk by a member of staff. 相似文献

OBJECTIVE: Reduce texture sensitivity on the Rorschach is proposed as a sequela of early sexual abuse that is unlikely to be contaminated by situational variables. If this conceptualization has merit, texture attributes offer a roadmap for studying vying claims in the recovered memory debate. To explore this possibility, we examined the extent to which intense preoccupation with sexual trauma of childhood and of adult onset was related to reduced texture productivity. METHOD: Texture productivity was measured in 4 groups comprised of 108 patients using the Rorschach. Twenty-seven patients with recovered memory were compared with 27 patients with continuous memory of childhood sexual trauma, 27 post trauma stress patients with sexual trauma of adult onset, and 27 non-abused patients. RESULTS: The study replicated previous findings of reduced texture productivity among patients who always remembered sexual trauma of childhood-onset. The same texture deficiency pattern was observed among patients who recovered memory of childhood sexual abuse. This pattern was not observed in Post Traumatic Stress Disorder (PTSD) patients intensely preoccupied with sexual trauma of adult onset despite the fact that they mimicked the recovered memory group in respect to enduring preoccupation with distressing thoughts of sexual abuse. CONCLUSION: The findings indicate that intrusive memories of sexual trauma do not shape patients' response to textural cues on the Rorschach. Variations in texture productivity are primarily moderated by age of trauma onset. Dismissal of claims of recovered memories on the basis of intense sexual preoccupation is not warranted. 相似文献
