Using action research to evaluate a nursing orientation program in a multicultural acute healthcare setting

Objectives:Competence motivates newly employed nurses to provide high-quality care,which leads to appropriate patient care and satisfaction.A nursing orientation program can have a positive impact on new nurses who are joining healthcare organizations.The research examined the orientation program for new nurses in a multicultural setting to redesign the program.Methods:The study was carried out in a multicultural tertiary setting.Action research was used as a research strategy with qualitative content analysis and quantitative evaluation.Seventy nurses were part of the orientation program.The competence of the nurses was assessed using the Nurse Competence Scale.Focus-group discussions were also conducted to find the views of the beneficiaries about the program.Results:The study revealed that the overall competence was high,and there was an overall gain in the competence score(5.48%)among the nurses.Among their competence in different dimensions,new nurses had a maximum gain in competence for the dimension of ensuring quality.However,they showed low competence gain in teaching coaching.The results show that the difference in the overall pre-and post-test scores was statistically significant(P<0.05)in all dimensions except teaching coaching and managing situations,and the program was effective.However,a few challenges were identified in the program.Conclusions:New nurses were found to be competent,and the orientation program had a significant impact on the competence of the nurses.The findings emphasized the need for modification of some content and strategy for future programs.The strategies developed from the findings were presented.This helps hospitals to consider examining specific aspects of the orientation program and redesigning it so it can enrich the experiences of new nurses.

Demands of experiential training for ICU nurses in Hunan of China

Objective:To assess intensive care unit(ICU)nurses’demands for specialized experiential training and to provide inputs for developing an experiential training program for ICU nurses.Methods:A questionnaire for assessing ICU nurses’demands for experiential specialty training was distributed to 360 ICU nurses,selected through purposive sampling from two secondary hospitals and six tertiary hospitals in Hunan Province,China.Results:Of the survey participants,63.6%had undergone a specialty training program for ICU nurses.Of these individuals,53.0%were satisfied with the training.Certification as a qualified nurse was considered an essential criterion for admission of trainees into the program by 81.8%of respondents,while 77.1%of respondents considered clinical working experience to be a critical requirement for selecting trainers.A total of 48.1%of the respondents preferred part-time training,and 36.1%considered a training cycle of 9 e12 weeks to be reasonable.Moreover,they felt that the training methods should be tailored to different stages of the experiential learning cycle.Demands for experiential training among ICU nurses were quantified,with high demand reflected in an overall score of 4.41±0.48.The“intensive care technology”experiential training module was ranked highest in terms of demand,with the top five sub-modules being specialty operating technology(4.67±0.53),care of critically ill patients(4.66±0.55),critical patient rescue procedures(4.65±0.56),assessing monitoring indexes(4.63±0.56),and the application of relevant instruments(4.61±0.57).Conclusion:Nearly half of the respondents indicated that their experiences of specialty training programs were not satisfactory,and they had high demands for experiential training.Thus,to optimize training outcomes,continuous updating of training methods is essential.Moreover,a systematic,comprehensive,and multilevel experiential training program that targets the specific needs of ICU nurses is essential.

A simple and inexpensive method for muddy shore profiling

There are several well-established methods for obtaining beach profiles, and more accurate and precise high-tech methods are emerging. Traditional low-cost methods requiring minimal user skill or training are still popular among professionals, scientists, and coastal zone management practitioners. Simple methods are being developed with a primary focus on sand and gravel beaches. This paper describes a simple, low-cost, manual field method for measuring profiles of beaches, which is particularly suitable for muddy shores. The equipment is a type of flexible U-tube manometer that uses liquid columns in vertical tubes to measure differences in elevation; the supporting frame is constructed from wooden poles with base disks, which hold measuring scales and a PVC tube. The structure was trialed on a mudflat characterized by a 20~0-cm-thick surface layer of silt and clay, located at the Kutubdia Island, Bangladesh. The study results are discussed with notes on the method＇s applicability, advantages and limitations, and several optional modifications for different scenarios for routine profiling of muddy shores. The equipment can be used by one person or two people, and the accuracy of the method is comparable to those in other methods. The equipment can also be used on sandy or gravel beaches.

A Holistic Course Design for Intercultural Business Communication Based on CLT A Case Study of a Training Program for Chinese Business Professionals

BE （Business English） has been unprecedentedly emphasized and gradually developed into an independent discipline. The paper aims to explore a holistic course design for business professionals in IBC （Intercultural Business Communication） based on CLT （Communicative Language Teaching）. The proposed course design encompasses three-dimensional contents： comprehensive language and expertise training, intercultural communicative competence cultivation, and intercultural PBL （project-based learning）. A survey is conducted in a training program of Chinese business professionals in international institutions. Three principles are identified： （1） BE teaching is need-oriented, so the pedagogical methods should be tailored to meet the international workplace requirements; （2） The linguistic and professional knowledge acquisition is achieved through communicative function of the target language; and （3） Learners＇ participation in intercultural PBL can stimulate learners＇ interest and enhance their operational capabilities. The findings of the case study indicate that a holistic course design is： （1） Course syllabus should not be formed without taking the leamers＇ expectation and feedback into consideration; （2） Teaching strategies should be innovated to enhance learners＇ communicative confidence and competence; and （3） Teaching materials should be adapted and subjected to modification according to the authentic language used in intercultural settings. The study outcomes may also shed light on other disciplines of ESP teaching.

Risk factors of military training-related injuries in recruits of Chinese People's Armed Police Forces

Objective: To assess the incidence, types and risk factors of military training related injuries in recruits of Chinese People’s Armed Police Forces (CPAPF). Methods: A cohort study was made on the risk factors of injuries in 805 male recruits during the military training from December 25, 1999 to December 25, 2000. Results: A total of 111 recruits (14%) experienced one or more injuries, and the cumulative incidence was 16.1 injuries per 100 soldiers in a year. And 77.7 % of the injuries belonged to overuse injuries of the skeletal and muscular systems, the most common type of which was stress fractures. Most injuries occurred in the 3rd month of training. Univariate analysis and logistic regression analysis of possible risk factors for overuse injuries were carried out, and a number of risk factors were identified: history of agricultural labor, history of lower limb injury, flatfoot and less running exercise before entry into the army. But a suitable body mass index (BMI) was a protective factor. Examination of age, body height, smoking, body flexibility and frequency of 2 mile running revealed no significant association with the injuries. Conclusions: History of agricultural labor, history of lower limb injury, flatfoot, less running exercise before entry into the army and lower BMI were risk factors of the overuse injuries. In order to decrease the incidence of overuse injuries, the young people with good physical ability and shapely body type should be selected during conscription. During the training, nutrition should be improved so as to decrease the incidence of injuries.
