Hepatitis B (HB) is a deadly disease that has a severe impact on infected individuals. In China, not only are the incidence and infection rates of HB very high, but also many HB patients suffer from mental illness associated with anxiety and fear because of HB-associated symptoms. This exacerbates the patients’ condition, potentially increasing the risk of mortality. In this paper, we propose a new treatment mode to improve the therapeutic efficiency and patients’ satisfaction with their healthcare. In a single process of this new treatment, several patients with similar disease symptoms are treated by one doctor at the same time. This new treatment mode can not only relieve the anxiety and fear of HB patients, and improve patients’ cognition rate of HB, but also reduce the HB infection rate, slow down the progression of disease symptoms, and shorten the course. If patients with similar disease symptoms are to be grouped together, there is a need to determine the optimal patient batch combination, which can be solved in the new mode, called patient combined problem (PCP). We also constructed a mathematical model of PCP, and present the ant colony (AC) algorithm and Enhanced AC with a P-3-exchange operator for PCP in the new treatment mode in this paper. We also performed an experiment that showed that our proposed algorithms are very fast and effective for solving this problem.

专业学位研究生教育不同于学术学位研究生的教育,它培养的是具有深厚知识基础的高级应用型人才.专业学位研究生教育重要的知识基础之一就是实践者个体的实践知识.实践知识是实践者在实践过程中积累起来直接用于实践的知识.实践知识具有实践性、个人性、社会性、连续性、情境性、缄默性.对专业学位研究生教育而言,实践知识的提出意味着要关注学习者或者实践者现有的个人的实践知识,注重实践者自我实践知识与他人实践知识、理论知识的互动,承认实践者或者学习者作为知识创造者的合法地位,建构平等的师生关系,注重叙事在专业学位研究生教育中的重要作用.  相似文献

信任对 CSA 经济的可持续至关重要。 文章基于信任建立过程和信任发展的阶段性理论,通过单案例的研究方法探讨如何构建社区支持农业中的消费者信任。 研究结果表明:消费者信任的建立分为初始信任与持续信任两个阶段。 在潜在消费者的初始信任阶段,直接或间接关系、公开的信息、农 场主特征和消费体验会引发消费者的计算过程、转移过程、预测过程、意图过程和能力过程而建立消费 者初始信任。 在会员的持续信任阶段,用户体验和社会联系会引发消费者的预测过程和意图过程而维 持会员对农场的信任。  相似文献

Infants’ emerging ability to move independently by crawling is associated with changes in multiple domains, including an increase in expressions of anger in situations that block infants’ goals, but it is unknown whether increased anger is specifically because of experience with being able to move autonomously or simply related to age. To examine the influence of locomotion on developmental change in anger, infants’ (N = 20) anger expressions during an arm restraint procedure were observed longitudinally at a precrawling baseline assessment and 2 and 6 weeks after the onset of crawling. Infant age at each crawling stage was unrelated to the frequency of anger expressed in response to arm restraint. At 6 weeks postcrawling onset, infants whose mothers rated them as temperamentally higher in distress to limitations, compared with those rated lower, showed a greater increase in the frequency of anger expressed during the arm restraint relative to earlier assessments and took longer to reduce the frequency of anger expressed when no longer restrained. Findings suggest that experience with autonomous crawling has an effect on anger expression, independent of age, and that a temperamental tendency to become distressed by limitations may exacerbate the effect of crawling on anger expression.  相似文献

The objective of this article is to discuss a needed paradigm shift in disaster risk analysis to emphasize the role of the workforce in managing the recovery of interdependent infrastructure and economic systems. Much of the work that has been done on disaster risk analysis has focused primarily on preparedness and recovery strategies for disrupted infrastructure systems. The reliability of systems such as transportation, electric power, and telecommunications is crucial in sustaining business processes, supply chains, and regional livelihoods, as well as ensuring the availability of vital services in the aftermath of disasters. There has been a growing momentum in recognizing workforce criticality in the aftermath of disasters; nevertheless, significant gaps still remain in modeling, assessing, and managing workforce disruptions and their associated ripple effects to other interdependent systems. The workforce plays a pivotal role in ensuring that a disrupted region continues to function and subsequently recover from the adverse effects of disasters. With this in mind, this article presents a review of recent studies that have underscored the criticality of workforce sectors in formulating synergistic preparedness and recovery policies for interdependent infrastructure and regional economic systems.  相似文献

华裔作家谭恩美的小说《接骨师之女》一出版就引起了国内研究者的关注。从最近十年国内公开发表的论文看,不论是文章的数量,还是文章的质量都呈现出持续发展的态势,研究者从不同的角度对作品展开解读。但是,系统回顾小说《接》的国内研究现状,不难发现,当前对该作品的研究仍然存在不少的问题:如主题内容过于集中,研究视角狭窄且多重复,研究的深度有待提高等等。如果这些问题得到妥善解决,小说《接骨师之女》仍然具有较大的研究空间,其前景也令人期待。  相似文献
