Based on the perspectives of social risk amplification and the knowledge-attitudes-practice model, this study aimed to test how the level of knowledge about COVID-19 and information sources can predict people's behavioral changes and to examine the effect mechanisms through the mediating roles of attitude, risk perception, and negative emotions in a survey of 498 older Chinese adults. The results showed that (1) older people had a lower level of factual knowledge regarding the variant strains and vaccines; (2) in the information sources-behavior, information sources had a critical influence on elderly individuals' coping behaviors; and (3) in the knowledge-behavior, factual knowledge had a significant effect on elderly individuals' coping behaviors. Specifically, for prevention behaviors, both risk perception and negative emotions played full mediating roles. The findings have significant implications for the development of an effective COVID-19 prevention program to older adults coping with pandemic conditions.
本研究基于社会风险放大视角和知识-态度-实践模型,以498名中国老年人为研究对象,通过态度、风险感知和负面情绪的中介作用,检验新冠肺炎知识水平和信息来源对人们行为变化的预测作用,并探讨其作用机制。结果表明:(1)老年人对变异毒株和疫苗的事实知识水平较低;(2)在信息源-行为中,信息源对老年人应对行为有重要影响;(3)在知识-行为方面,事实性知识对老年人应对行为有显著影响。具体而言,对于预防行为,风险感知和负性情绪都发挥了充分的中介作用。这些发现对制定有效的COVID-19预防计划,为老年人应对大流行状况具有重要意义。

In response to the COVID-19 outbreak, the governments of different countries adopted, such as locking down cities and restricting travel and social contact. Online health communities (OHCs) with specialized physicians have become an important way for the elderly to access health information and social support, which has expanded their use since the outbreak. This paper examines the factors influencing elderly people’s behavior in terms of the continuous use of OHCs from a social support perspective, to understand the impact of public health emergencies. Research collected data from March to April 2019, February 2020, and August 2021, in China. A total of 189 samples were collected and analyzed by using SmartPLS. The results show that (1) social support to the elderly during different stages has different influences on their sense of community and (2) the influence of the sense of community on the intention to continuously use OHCs also seems to change over time. The results of this study provide important implications for research and practice related to both OHCs and COVID-19.

In this paper, Artificial Intelligence assisted rule-based confidence metric (AI-CRBM) framework has been introduced for analyzing environmental governance expense prediction reform. A metric method is to assess a level of collective environmental governance representing general, government, and corporate aspects. The equilibrium approach is used to calculate improvements in the source of environmental management based on cost, and it is tailored to test the public sector-corporation for environmental shared governance. The overall concept of cost prediction or estimation of environmental governance is achieved by the rule-based confidence method. The framework compares the expected cost to the environment of governance to determine the efficiency of the cost prediction process.

Online medical communities have revolutionized the way patients obtain medical-related information and services. Investigating what factors might influence patients’ satisfaction with doctors and predicting their satisfaction can help patients narrow down their choices and increase their loyalty towards online medical communities. Considering the imbalanced feature of dataset collected from Good Doctor, we integrated XGBoost and SMOTE algorithm to examine what factors and these factors can be used to predict patient satisfaction. SMOTE algorithm addresses the imbalanced issue by oversampling imbalanced classification datasets. And XGBoost algorithm is an ensemble of decision trees algorithm where new trees fix errors of existing trees. The experimental results demonstrate that SMOTE and XGBoost algorithm can achieve better performance. We further analyzed the role of features played in satisfaction prediction from two levels: individual feature level and feature combination level.
在线医疗社区已经彻底改变了患者获取医疗相关信息和服务的方式。调查哪些因素可能影响患者对医生的满意度,并预测他们的满意度,可以帮助患者缩小他们的选择范围,提高他们对在线医疗社区的忠诚度。考虑到《好医生》数据集的不平衡特征,我们结合XGBoost和SMOTE算法来检验哪些因素和这些因素可以用来预测患者满意度。SMOTE算法通过对不平衡分类数据集进行过采样来解决不平衡问题。而XGBoost算法是一种决策树的集合算法,用新树来修正现有树的错误。实验结果表明,SMOTE和XGBoost算法可以获得更好的性能。我们进一步从个体特征水平和特征组合水平两个层面分析特征在满意度预测中的作用。

This article reports on an investigation into how to improve problem formulation and ideation in Design Science Research (DSR) within the mHealth domain. A Systematic Literature Review of problem formulation in published mHealth DSR papers found that problem formulation is often only weakly performed, with shortcomings in stakeholder analysis, patient-centricity, clinical input, use of kernel theory, and problem analysis. The study proposes using Coloured Cognitive Mapping for DSR (CCM4DSR) as a tool to improve problem formulation in mHealth DSR. A case study using CCM4DSR found that using CCM4DSR provided a more comprehensive problem formulation and analysis, highlighting aspects that, until CCM4DSR was used, weren’t apparent to the research team and which served as a better basis for mHealth feature ideation.
本文报告了一项关于如何在移动健康领域改善设计科学研究(DSR)中的问题制定和构思的调查。对已发表的移动健康DSR论文中问题制定的系统文献综述发现,问题制定通常执行得很弱,在利益相关者分析、以患者为中心、临床投入、核理论的使用和问题分析方面存在缺陷。该研究建议使用彩色认知映射的DSR (CCM4DSR)作为一种工具来改进移动健康DSR中的问题制定。使用CCM4DSR的案例研究发现,使用CCM4DSR提供了更全面的问题表述和分析,突出了研究团队在使用CCM4DSR之前不明显的方面,这为移动健康功能构想提供了更好的基础。

Healthcare insurance fraud influences not only organizations by overburdening the already fragile healthcare systems, but also individuals in terms of increasing premiums in health insurance and even fatalities. Identifying the behavioral characteristics of fraudulent claims can help shed light on the development of artificial intelligence and machine learning technologies to detect fraud in health information system research. In this paper, a theoretical model of medical insurance fraud identification is proposed, which characterizes the judgment variables of fraud from the three dimensions of time, quantity, and expenses. The model is verified with large-scale, real-world medical records. Our study shows that, in comparison with claims made by normal people, fraudulent claims usually have a greater frequency of hospital visits, and more medical bills, accompanied by higher amounts of medical expenses. An interesting discovery is that the price per bill for fraudulent cases is not statistically different from the normal cases.
医疗保险欺诈不仅会给本已脆弱的医疗保健系统带来过重负担,还会影响个人,增加医疗保险的保费,甚至导致死亡。识别欺诈性索赔的行为特征有助于揭示人工智能和机器学习技术的发展,以检测卫生信息系统研究中的欺诈行为。本文提出了一个医疗保险欺诈识别的理论模型,该模型从时间、数量和费用三个维度来表征欺诈的判断变量。该模型用大规模的真实医疗记录进行了验证。我们的研究表明,与正常人的索赔相比,欺诈性索赔通常有更频繁的医院就诊,更多的医疗账单,伴随着更高的医疗费用。一个有趣的发现是,欺诈案件的每张账单的价格在统计上与正常案件并无不同。

This purpose of this study is to develop a research model by extending the theory of planned behavior in a new application context, and applies it to investigate the extrinsic factors influencing people’s attitude towards donating to medical crowdfunding projects appearing on mobile social networking sites (MSNS) and their intention to donate. A survey of 356 Chinese users was conducted and structural equation modeling was used to validate the proposed model and hypotheses. The results indicate that project information, retweeter information and MSNS information all have the significant effect on the general attitude towards donating to medical crowdfunding projects, and general attitude positively affects people’s donation intention. In addition, perceived behavioral control also has positive effect on people’s donation intention, while experienced donating to medical crowdfunding projects has negative effect on people’s donation intention. The research findings provide important theoretical and practical implications.

As M-Health apps become more popular, users can access more mobile health information (MHI) through these platforms. Yet one preeminent question among both researchers and practitioners is how to bridge the gap between simply providing MHI and persuading users to buy into the MHI for health self-management. To solve this challenge, this study extends the Elaboration Likelihood Model to explore how to make MHI advice persuasive by identifying the important central and peripheral cues of MHI under individual difference. The proposed research model was validated through a survey. The results confirm that (1) both information matching and platform credibility, as central and peripheral cues, respectively, have significant positive effects on attitudes toward MHI, but only information matching could directly affect health behavior changes; (2) health concern significantly moderates the link between information matching and cognitive attitude and only marginally moderates the link between platform credibility and attitudes. Theoretical and practical implications are also discussed.
随着移动健康应用程序越来越受欢迎,用户可以通过这些平台访问更多的移动健康信息(MHI)。然而,研究人员和从业人员面临的一个突出问题是,如何弥合简单地提供MHI和说服用户购买MHI以进行健康自我管理之间的差距。为了解决这一挑战,本研究扩展了精化可能性模型,通过识别个体差异下MHI的重要中枢和外围线索,探索如何使MHI建议具有说服力。通过调查验证了所提出的研究模型。结果表明:(1)信息匹配和平台可信度分别作为中心和外围线索,对MHI态度有显著的正向影响,但只有信息匹配才能直接影响健康行为的改变;(2)健康关注显著调节信息匹配与认知态度之间的联系,仅轻微调节平台可信度与态度之间的联系。本文还讨论了理论和实践意义。

To reduce the incidence of cerebrovascular disease and mortality, identifying the risks of cerebrovascular disease in advance and taking certain preventive measures are significant. This article was aimed to investigate the risk factors of cerebrovascular disease (CVD) in the primary prevention, and to build an early warning model based on the existing technology. The authors use the information entropy algorithm of rough set theory to establish the index system suitable for early warning model. Then, using the limited Boltzmann machine and direction propagation algorithm, the depth trust network is established by building and stacking RBM, and the back propagation is used to fine-tune the parameters of the network at the top layer. Compared with the LM-BP early-warning model, the deep confidence network model is more effective than traditional artificial neural network, which can help to identify the risk of cerebrovascular disease in advance and promote the primary prevention.
提前识别脑血管疾病的危险因素,采取一定的预防措施,对降低脑血管疾病的发病率和死亡率具有重要意义。本文旨在探讨脑血管病(CVD)一级预防中的危险因素,并在现有技术基础上建立预警模型。利用粗糙集理论中的信息熵算法,建立了适合于预警模型的指标体系。然后,利用有限玻尔兹曼机和方向传播算法,通过构建和叠加RBM建立深度信任网络,并利用反向传播对网络顶层参数进行微调。与LM-BP预警模型相比,深度置信网络模型比传统人工神经网络更有效,有助于提前识别脑血管疾病风险,促进一级预防。

Compared with the LM-BP early-warning model, the deep confidence network model is more effective than traditional artificial neural network, which can help to identify the risk of cerebrovascular disease in advance and promote the primary prevention.","PeriodicalId":49029,"journal":{"name":"Journal of Organizational and End User Computing","volume":"129 1","pages":"1-14"},"PeriodicalIF":6.5,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72837864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

eHealth service has received increasing attention. Patients can consult online doctors via the Internet, and then physically visit the doctors for further diagnosis and treatments. Although extant research has focused on the adoption of eHealth services, the decision-making process from online to offline health services still remains unclear. This study aims to examine patients’ decisions to use online and offline health services by integrating the extended valence framework and the halo effect. By analyzing 221 samples with online consultation experiences, the results show that trust significantly influences perceived benefits and perceived risks, while trust, perceived benefits, and perceived risks significantly influence the intention to consult. The intention to consult positively influences the intention to visit. Considering the moderating effects of payment types, the influence of perceived risks on the intention to consult is larger for the free group than for the paid group. The findings are useful to better understand patients’ decisions to use eHealth.
电子医疗服务受到越来越多的关注。患者可以通过互联网咨询在线医生,然后亲自去看医生进行进一步的诊断和治疗。尽管现有的研究集中在电子医疗服务的采用上,但从在线到离线医疗服务的决策过程仍然不清楚。本研究旨在通过整合扩展价框架和光环效应来检验患者使用线上和线下医疗服务的决策。通过对221个有在线咨询经历的样本进行分析,结果表明,信任显著影响感知利益和感知风险,而信任、感知利益和感知风险显著影响咨询意愿。咨询意向正向影响访问意向。考虑到付费类型的调节作用,免费组的感知风险对咨询意愿的影响大于付费组。这些发现有助于更好地理解患者使用电子健康的决定。
