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

Reputation mechanism is introduced and Bayesian approach is based on, in which government supervision as well as consumer purchasing behavior is taken as crucial factors to impact on the food quality security. As to the proposed quantitative indicators, government supervision includes exposure rate, fine and etc.;at the same time, consumer purchasing behavior includes consumer’s WTP for security food and consumer expectations to food safety. Taking China’s dairy industry as an example, it makes simulation by Netlog. The results show that consumer purchasing behavior alone has little effect on the dairy companies’ decision-making to be honest or counterfeiting enterprises. However, combination government supervision with purchasing behavior has great impact, and plays very good effects on food safety.展开更多

Food safety is related to people's fundamental interests,affecting people's basic health. It is an important factor in promoting people's livelihood development and social progress. Compared with European countries and the United States in developed food safety supervision systems,the development of food safety supervision system in China is still relatively backward. As food safety supervision is not in place,food safety incidents have occurred in recent years,so that public's panic about food safety has intensified. It has a strong impact on social stability and the food economy. Thus,strengthening the construction of food safety supervision system is imperative. Since experiencing a series of food safety incidents,the EU has gradually improved its food safety supervision system and has developed the most comprehensive and mature food safety supervision system in the world. On the basis of sorting out the characteristics of EU's food safety supervision system,the development direction of China's food safety supervision system is proposed from four aspects: supervisor,legal system,law enforcement ability and safety standards.展开更多

The aim was to explore NSSs’ experiences of clinical supervision (CS) during their postgraduate clinical education. 46 NSS answered open-ended questions and their responses were analysed by means of a qualitative content analysis. The response rate was 82%. One main theme emerged: CS as a prerequisite for professional development and two domains: A reflective way of growing and learning through CS and The meaning of being and acting in a reflective and professional manner to ensure patient safety (PS). The results indicate that reflection is a crucial part of the NSS’ experiences of CS during their postgraduate clinical education. The supervisor’s ability to confirm the students, mutual trust and feeling safe in the relationship with the supervisor are of great importance. The students highlighted the value of continuity in CS and being supported yet challenged. The supervisor has great responsibility for the NSS’ development of professional clinical competence. The supervisor’s personal and professional skills, in addition to her/his ability to provide CS are important for PS as well as for professional and interdisciplinary teamwork. Acting in a reflective and professional manner is of great importance for ensuring PS. Although most of the students reported being sufficiently competent to ensure PS and agreed that CS and reflection are of great importance for PS, they wanted more time to reflect on their actions together with their supervisor. In conclusion, CS has the potential to lead to quality improvement. However, in order to enhance reflective practice, which is a prerequisite for CS and PS, we recommend closer cooperation between the university college and clinical supervisors, as well as a formal master level education for clinical supervisors.展开更多

An additional aim was to interpret the results and link them to non-technical skills and Patient Safety (PS) topics. The research question was: What are the benefits of clinical supervision focusing on non-technical skills in the area of PS? A cross-sectional study of 46 nurse specialist students was conducted by means of questionnaires and exploratory factor analysis. Factors that influenced the nurse specialist students’ competencies were: interpersonal, professional and communication skills in addition to awareness of ethical skills, the importance of teamwork and the benefit of involving patients and their family members in safe care. The results were linked to non-technical skills and PS competencies. Clinical supervision is crucial for the development of non-technical skills and PS competencies among nurse specialist students. However, finding time to reflect and learn from the supervision was reported to be a problem. Over half of the students stated they did not have enough time for supervision. Thus, there is a potential for quality improvement. We recommend that universities should provide formal educational programmes for supervisors focusing on the professional development of students, especially in the area of non-technical skills. In conclusion, CS should be prioritised by management and clinical leaders as it enhances PS.展开更多

China, as one of the world's largest food producers and consumers, pays a lot of attention to food safety issues. In recent years, China has taken actions and implemented a series of plans in respect to food safety. Food safety control systems including regulatory, supervisory, and science and technology systems, have begun to be established in China. Using, as a base, an analysis of the current Chinese food safety control system as measured against international standards, this paper discusses the need for China to standardize its food safety control system. We then suggest some policies and measures to improve the Chinese food safety control system.展开更多

The results indicate that the agro-products quality and safety levels improves steadily, and the supervision system and standardization system are both enhanced significantly, however, certain challenges still remain in each stage of the supply chain and the entire supervision process. Finally, five recommendations regarding four aspects (production, processing, circulation, and consumption) are concluded.

文摘When mining extra-thick coal seams,the main cause of strong ground pressure are the high-level thick and hard strata,but as yet there is no active and effective control technology.This paper proposes the method of subjecting hard roofs to ground fracturing,and physical simulation is used to study the control effect of ground fracturing on the strata structure and energy release.The results show that ground fracturing changes the structural characteristics of the strata and reduces the energy release intensity and the spatial extent of overburden movement,thereby exerting significant control on the ground pressure.The Datong mining area in China is selected as the engineering background.An engineering test was conducted on site by ground horizontal well fracturing,and a 20-m-thick hard rock layer located 110 m vertically above the coal seam was targeted as the fracturing layer.On-site microseismic monitoring shows that the crack propagation length is up to 216 m and the height is up to 50 m.On-site mine pressure monitoring shows that(1)the roadway deformation is reduced to 100 mm,(2)the periodic weighting characteristics of the hydraulic supports are not obvious,and(3)the ground pressure in the working face is controlled significantly,thereby showing that the ground fracturing is successful.Ground fracturing changed the breaking characteristics of the high-level hard strata,thereby helping to ameliorate the stress concentration in the stope and providing an effective control approach for hard rock.
文摘Most countries have expended much effort to develop food safety control systems to ensure safe food supplies within their borders. China, as one of the world's largest food producers and consumers, pays a lot of attention to food safety issues. In recent years, China has taken actions and implemented a series of plans in respect to food safety. Food safety control systems including regulatory, supervisory, and science and technology systems, have begun to be established in China. Using, as a base, an analysis of the current Chinese food safety control system as measured against international standards, this paper discusses the need for China to standardize its food safety control system. We then suggest some policies and measures to improve the Chinese food safety control system.
