文章通过调研发现,襄阳市卫生健康委员会、市疾控中心、市结核病防治院、市职业病防治院、市妇幼保健院等履行公共卫生职责的单位中具有预防医学专业背景的公共卫生人员占比不到50%。在基层公共管理服务部门几乎没有公共卫生专业人员,多是从其他医学类专业如护理专业、临床医学专业进行转化而来,基层临床公共卫生混合型人才极度匮乏。而本科及其以上学历的公共卫生人才目前很少下沉到基层,故加快公共卫生人才培养非常重要。  相似文献

Improving educational outcomes for Indigenous Australian students is a key strategy to helping Indigenous people reach their full potential. This has resulted in well-intentioned efforts by Australian educators and governments to ensure Indigenous children have positive school experiences. However, Indigenous students still lag behind their non-Indigenous counterparts in educational outcomes. This is particularly so for Indigenous students living in rural and remote parts of Australia where educational opportunities are limited, especially in high school. One solution to this problem has been to enrol these students in boarding schools in urban and metropolitan centres. While research on the success of boarding schools for Indigenous students is scarce, what little that does exist is not encouraging. The focus of this research was to examine the effects of boarding for Indigenous (= 11) and non-Indigenous students’ (= 158) wellbeing (= 1423) in two large private boys’ schools. Participating students aged 12–18 years old completed a survey measuring wellbeing constructs on two occasions, 12 months apart. Non-Indigenous boys were generally higher in wellbeing compared with Indigenous boys. There was also evidence of improved social wellbeing beyond that of non-Indigenous boarders over time. Overall, while evidence of merit was weak, boarding schools may benefit their Indigenous students’ development in social wellbeing.  相似文献

Although visual arts teachers have free access to high quality online artwork images offering them immense teaching resources, making meaningful use of them remains a pedagogical challenge. During the COVID-19 pandemic, the transition from face-to-face to online teaching caused an immediate need for teachers to enhance their digital competencies and technological capability for planning and delivering a blended art curriculum. Herein, I propose a ‘teacher-curator pedagogy’ via a study in six primary and secondary schools in Hong Kong to assess its effectiveness. The study took place in the academic year of 2021-22 with 331 student participants. The proposed pedagogy puts visual arts teachers in the role of ‘digital curators’ who create virtual exhibitions for teaching art appreciation and artmaking. This paper addresses the theoretical framework, implementation strategies, and the results of the study highlighting its effectiveness, impact and limitations on teaching when using teacher-curated virtual exhibitions in both physical and virtual learning contexts. It was found that the technological capacity and confidence of the teacher participants was enhanced through the use of online resources and virtual exhibition tools. Making use of the 3D presentation of exhibits in themes and context through digital content curation, the teachers engaged students with deep interaction through the blending of online and face-to-face teaching. However, the proposed pedagogy was limited by the high demand of training and preparation work, hardware and software support, and difficulties in assessing and monitoring learning beyond class.  相似文献

An improvement on the transient response of tracking for the sampled-data system based on an improved PD-type iterative learning control (ILC) is proposed in this paper. The developed analog ILC method and the high-gain property tracker design methodology are first combined to significantly reduce learning epochs and overcome the initial condition shift problem and discontinuous reference input in the traditional ILC. Besides, the proposed ILC improves the transient response and decreases the rate of weighting matrices QQ to RR under the traditional linear quadratic tracker design. First, the off-line observer/Kalman filter identification (OKID) is used to determine the appropriate (low-) order system parameters and state estimator for the physical system with unknown system equation, so that the model-based PD-type ILC can be implemented for practical applications. Then, to improve the transient response and decrease the control effort, the proportional difference type (PD-type) ILC algorithm is combined with the high-gain property linear quadratic tracker (LQT) design to construct the high performance tracker for the model-based sampled-data systems. Furthermore, the discrete-time version high performance tracker design for the unknown stochastic sampled-data system via the iterative learning control method is proposed in this paper based on the Euler method and the digital redesign approach. Finally, some examples are given for illustrating the effectiveness of the proposed method.  相似文献

Motivated by the requirement for safe and pinpoint soft landing in future asteroids missions, a soft landing control method based on finite-time control (FTC) technique is developed in this paper. Firstly, in order to utilize the design philosophy of cascaded system, the landing error dynamics of asteroid probe are divided into two subsystems, including a position error subsystem (PES) and a line-of-sight angle error subsystem (LOSAES). Secondly, homogeneous system theory is employed to design the control law for LOSAES such that the states of LOSAES will be stabilized to the origin in finite time. For the reduced PES subsystem, a FTC law is designed such that the rest of states will converge to zero in finite time. Strict analysis shows that the whole system satisfies the finite time stability. Simulation results demonstrate that the proposed method provides faster convergence rates and better disturbance rejection properties compared with the traditional asymptotically stable control (ASC) method.  相似文献
