Objective:Healthcare workers,as a high-stress professional group,face long-term high intensity workloads and complex medical environments,resulting in increasingly prominent mental health issues.In particular,the widespread presence of anxiety symptoms and somatic pain has become a major factor affecting both the quality of care and the career development of healthcare workers.This study aims to investigate the mediating and moderating roles of psychological resilience and sleep in the relationship between somatic pain and anxiety among healthcare workers.Methods:A cross-sectional questionnaire survey was conducted among 1661 healthcare workers.The instruments used included the Generalized Anxiety Disorder-7(GAD-7),item 3 from the Patient Health Questionnaire-9(PHQ-9),the 10-item Connor-Davidson Resilience Scale(CD-RISC-10)for psychological resilience,and the Visual Analogue Scale(VAS)for assessing anxiety,sleep disturbance,psychological resilience,and somatic pain.Results:The detection rate of anxiety symptoms among healthcare workers was 38.95%.Psychological resilience was significantly negatively correlated with anxiety symptoms(r=−0.451,P<0.01),sleep disturbance(r=−0.313,P<0.01),and somatic pain(r=−0.214,P<0.01).Moreover,psychological resilience partially mediated the relationship between somatic pain and anxiety(β=−0.103,P<0.01),and sleep quality moderated the latter part of the mediation model(“somatic pain-psychological resilience-anxiety”).Conclusion:Under high-intensity workloads,healthcare workers generally experience severe anxiety symptoms.Psychological resilience plays an important protective mediating role in their mental health,and sleep quality serves as a moderator in this relationship.Enhancing healthcare workers’psychological resilience and improving their sleep may promote both their physical and mental well-being. 展开更多

With the gradual acceleration of urbanization speed and continuous improvements of agricultural productivity, the number of migrant workers is increasing. The living conditions of this group in cities determine the quality of urbanization in China, and are of great and far-reaching significance to Chinese construction of comprehensive well-off society. This study took the migrant workers in Heilongjiang Province as the research object, and took the representative new-generation migrant workers as the respondent to have a comprehensive analysis of the employment status. The study focused on these aspects, such as nature information, employment selection, employment quality, and social security, etc. Finally, it provided valuable ideas and methods on the reasonable solutions of the employment problems of the migrant workers to better increase farmers' income and improve their living qualities. 展开更多

Java对多线程技术的支持,使得开发“启动”和“执行”分离的异步处理程序变得更加容易。利用Java多线程中经典的Worker模式,实现了多接口数据流传入,并有异步处理功能的SP(Server Provider)短消息模拟器。在实际应用中,模拟器表现出对持续大数据流不能即时处理,以及数据量较小情况的资源浪费问题。针对Worker模式的这些不足,引入了自适应Worker模式的概念,改进后的模拟器在实际应用中取得了较好的效果。 展开更多

Task allocation is a significant problem in MCS. Most previous studies mainly focused on stationary spatial tasks while neglecting the changes of tasks and workers. In this paper,the proposed hybrid two-phase task allocation algorithm considers heterogeneous tasks and diverse workers.For heterogeneous tasks,there are different start times and deadlines. In each round,the tasks are divided into urgent and non-urgent tasks. The diverse workers are classified into opportunistic and participatory workers.The former complete tasks on their way,so they only receive a fixed payment as employment compensation,while the latter commute a certain distance that a distance fee is paid to complete the tasks in each round as needed apart from basic employment compensation. The task allocation stage is divided into multiple rounds consisting of the opportunistic worker phase and the participatory worker phase. At the start of each round,the hiring of opportunistic workers is considered because they cost less to complete each task. The Poisson distribution is used to predict the location that the workers are going to visit,and greedily choose the ones with high utility. For participatory workers,the urgent tasks are clustered by employing hierarchical clustering after selecting the tasks from the uncompleted task set.After completing the above steps,the tasks are assigned to participatory workers by extending the Kuhn-Munkres (KM) algorithm.The rest of the uncompleted tasks are non-urgent tasks which are added to the task set for the next round.Experiments are conducted based on a real dataset,Brightkite,and three typical baseline methods are selected for comparison. Experimental results show that the proposed algorithm has better performance in terms of total cost as well as efficiency under the constraint that all tasks are completed. 展开更多
