Comparison and Enlightenment of China's and EU's Food Safety Supervision Systems

Food is the paramount necessity of the people,and safety is most essential for food. 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.

Skeleton-based Violation Action Recognition Method for Safety Supervision in Operation Field of Distribution Network Based on Graph Convolutional Network

Safety accidents in the operation field of the distribution network often occur,which seriously endanger the safety and lives of operators.Existing identification methods for safety risk can identify static safety risks,such as no-helmet,no-safety gloves,etc.,but fail to identify risks in the dynamic actions of operators.Therefore,this paper proposes a skeletonbased violation action-recognition method for supervision of safety during operations in a distribution network,i.e.,based on spatial temporal graph convolutional network(STGCN)and key joint attention module(KJAM),which can implement dynamic violation behavior recognition of operators.In this method,the human posture estimation method,i.e.Multi-Person Pose Estimation,is utilized to extract the skeleton information of operators during operations,and to construct an undirected graph,which reflects the movement and posture of the human body.Then,the STGCN is utilized to identify actions of operators that can lead to dynamic violations.In addition,the KJAM captures important joint information of operators.The effectiveness and superiority of the proposed method are verified in comparison to other action recognition methods.The experimental results show that the proposed method has higher recognition accuracy for common violations collected at the actual operation site of the distribution network and shows a strong generalization ability,which can be applied to the video monitoring system of field operations to reduce the occurrence of safety accidents.

The Impact of Government Supervision and Consumer Purchasing Behavior on Food Safety

This paper aims at the theoretical analysis to the impact of government supervision and consumer purchasing behavior on food quality security, so as to look for safety strategies and measures to strengthen and improve the level of food safety in China. 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.

Reflection as a Skill-Clinical Supervision as a Prerequisite for Professional Development to Ensure Patient Safety

This study is set in the context of the final phase of nurse specialist students’ (NSS) postgraduate education in surgical, oncological, anaesthesia and intensive care nursing at the University College in June 2015. 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.

Clinical Supervision and Non-Technical Professional Development Skills in the Context of Patient Safety—The Views of Nurse Specialist Students

The aim of the study was to evaluate nurse specialist students’ views of clinical supervision (CS) and its influence on their professional competence development. 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.

The Benefits of Person-Centred Clinical Supervision in Municipal Healthcare—Employees’Experience

Satisfied employees in healthcare services who have opportunities to develop their professional competence by reflecting on professional challenges play an important role in the quality of care. The aim of the present study was to describe the employees’ experience of the benefits of participating in a person-centred clinical supervision setting. The supervision, guided by a professional supervisor, was carried out with a group of six day- and night-shift municipal healthcare professionals for a period of four months during their mandatory work hours. Data were obtained from written individual evaluations and group interviews shortly after the last session and again twelve months later. The results showed that the participants experienced that their internal resources and coping skills had been strengthened by the supervision. They developed abilities to meet the challenges more constructively than before. New understandings gave them the opportunity to alternative actions in practice. Further intervention studies of person-centred clinical supervision must focus on such clinical outcomes as patient safety and professional development.
