The main problems existing in the supervision of rural food safety are analyzed as follows: first, the legislative work of rural food safety lags behind to some extent; second, the supervision of governmental departments on rural food safety is insufficient; third, the industrial supervision mechanism of rural food security is not perfect; fourth, the role of rural social organizations in supervising food safety is limited; fifth, the farmers' awareness of food safety supervision is not strong. Based on these problems, the targeted strategies of constructing diversified rural food safety supervision system are put forward as follows: accelerate the legislation of rural food safety, and ensure that there are laws to go by; give play to the dominant role of government, and strengthen administrative supervision on rural food safety; perfect industrial convention of rural food safety, and improve industrial supervision mechanism; actively support the fostering of social organizations, and give play to the role of supervision of organizations; cultivate correct concept of rights and obligations of farmers, and form awareness of food safety supervision.展开更多

Using the moving data windows technique, the static MPCA is extended for use in dy-namic process performance monitoring. The control chart is set up using the historical data collected from the past successful batches, thereby resulting in simplification of monitoring charts, easy tracking of the progress in each batch run, and monitoring the occurrence of the observable upsets. Data from the commercial-scale penicillin fer-mentation process are used to develop the rolling model. Using this method, faults are detected in real time and the corresponding measurements of these faults are directly made through inspection of a few simple plots (t-chart, SPE-chart, and T2-chart). Thus, the present methodology allows the process operator to actively monitor the data from several cultivations simultaneously.展开更多

However, the acquisition of the psychomotor skills required for successful practice and learning can only be acquired if student midwives are supported and guided by clinical supervisors in their learning environments. Main Objective: The main objective of the study was to determine factors influencing clinical supervision of Student Midwives in Lusaka Urban District. Methodology: A cross-sectional study design that employed both quantitative and qualitative methods was used. The study population comprised 124 Nurses and Midwives working in Lusaka urban District. Self-administered questionnaires were used to collect data from the Nurses and midwives and a focus group discussion guide was used to guide discussions with the student midwives at Lusaka College of Nursing and Midwifery and a total of three focus group discussions were conducted. Quantitative data were entered into by Statistical Package Social Sciences (SPSS) version 22 for windows. Chi-square test was used to test associations among variables. The confidence interval was set at 95% with a significance level of 0.05. Qualitative data were analysed using content analysis to classify words into themes and categories by looking for repeated ideas or patterns of thoughts. Results: The findings showed that a high percentage of the clinical supervisors (89.5%) had not been trained in clinical supervision and most respondents had moderate knowledge on clinical supervision of students. Majority of the respondents (63%) exhibited inadequate supervision skills. The attitudes of all the supervisors towards supervision were positive. A large percentage of respondents (73%) were competent in clinical supervision. However the learning environment considered to be poor by most respondents (61%). The study revealed a significant association between clinical supervision and the respondents’ knowledge on clinical supervision (p-value of 0.00). Conclusion: The current study showed that clinical supervision was untrained and had inadequate supervision skills and the learning environment was poor. There is need therefore to train clinical supervisors and improve the students’ learning environment in order to enhance teaching and learning. The study offers a valuable insight into the factors influencing students’ midwives learning in clinical learning environment.展开更多

Rather than focusing all attention on safety issues of working faces, supervising departments of coalmines are advised to pay much more attention to institutional factors that may impact people’s attitude and behavior, which are responsible for most coalmine accidents. It is believed that such a shift of attention can effectively reduce coalmining production accidents and greatly enhance supervision efficacy.展开更多

Access to resources is required for the development of a professional identity, which includes gaining technical knowledge and receiving feedback, guidance as well as social and emotional support from clinical supervisors. The aim of this study was to evaluate BSN students’ views of professional development after clinical supervision (CS) during their undergraduate education. An additional aim was to illuminate how competence development was related to the WHO Patient Safety Educational Model. A cross-sectional study was conducted, in which CS was measured as part of a survey completed by a sample of nursing students after their clinical placement at two time-points, namely 2012 and 2013. Statistical descriptive and inferential analyses were used and differences in the responses between Time 1 and Time 2 compared. The benefit of CS for nursing students’ competence development revealed a positive significant relationship between students’ Interpersonal skills and the factor Improved care/skills. There were differences in terms of variables related to the Importance value of CS and Professional skills. The results can be used to inform undergraduate nursing education leaders, teachers and practice partners on individual, group and organisational level in order to enhance patient safety and highlight the importance of CS for BSN students’ professional development.展开更多

文摘Objective:This study aims to determine the mediating effects of psychological empowerment on abusive supervision and turnover intention as perceived by nurses to provide information to change the status of nurse turnover.Methods:A cross-sectional survey(a questionnaire examining perceptions of abusive supervision,measurement of psychological empowerment,and questionnaire for turnover intention)was used to collect data.A total of 1127 clinical nurses,who were recruited through convenience sampling,participated in the survey.Results:Nurses'average perceived abusive supervision,psychological empowerment,and turnover intention scores were 1.62±0.95,3.24±0.83,and 14.17±3.78,respectively.Psychological empowerment was found to mediate the relationship between abusive supervision and turnover intention(P<0.01).Turnover intention tends to be stronger and psychological empowerment reduced when nurse managers adopt an abusive leadership style.Conclusions:Nurses'psychological empowerment is an intermediary variable that predicts the relationship between abusive supervision and turnover intention.Nurse managers should manage abusive supervision to increase nurses'psychological empowerment and decrease turnover intention.
