    气管内导管移位是临床环境中常见的患者安全事件。目前的临床实践,主要依靠床头目视检查和设备检查,通常无法及时检测气管导管移位或移位。这项研究涉及深度学习的发展,基于人工智能(AI)的管道位移监测系统。我们还提出了一个随机交叉实验,以评估与传统方法相比,这种基于AI的监测系统的有效性。评估将侧重于检测和处理管道异常的即时性,换档转换的完整性和准确性,以及创新扩散的程度。这项研究的结果有望为人工智能的发展和整合提供有价值的见解,以加强医疗和护理研究中的护理提供和促进创新扩散。
    Endotracheal tube dislodgement is a common patient safety incident in clinical settings. Current clinical practices, primarily relying on bedside visual inspections and equipment checks, often fail to detect endotracheal tube displacement or dislodgement promptly. This study involved the development of a deep learning, artificial intelligence (AI)-based system for monitoring tube displacement. We also propose a randomized crossover experiment to evaluate the effectiveness of this AI-based monitoring system compared to conventional methods. The assessment will focus on immediacy in detecting and handling of tube anomalies, the completeness and accuracy of shift transitions, and the degree of innovation diffusion. The findings from this research are expected to offer valuable insights into the development and integration of AI in enhancing care provision and facilitating innovation diffusion in medical and nursing research.

    背景:这项研究的目的是检查杭州大学生中电子烟(电子烟)的使用情况,并分析其使用电子烟意向的影响因素。
    方法:使用分层整群抽样方法,选择杭州两所大学的775名学生于2022年3月至4月进行现场问卷调查。对使用意愿的影响因素进行调整logistic回归分析,基于创新扩散理论。
    结果:在我们的大学生样本中,16.5%的学生尝试过电子烟;6.32%的学生在过去一个月中使用过电子烟,8.0%有使用电子烟的意向。不同性别之间使用电子烟的意愿存在显著差异,经济地位,身边亲密朋友的吸烟状况,以及他们自己使用烟草和酒精(p<0.05)。Logistic回归模型显示,电子烟的可观测性(AOR=1.28;p<0.05),个人因素(AOR=1.39;p<0.05),和社会系统(AOR=1.63;p<0.05),均为电子烟使用意向的影响因素。
    结论:杭州大学生使用电子烟的意愿很高,以及产品本身的影响,个体特征和生活环境至关重要。有必要在社会和家庭层面加强烟草知识的推广,以减少电子烟的发生。
    BACKGROUND: The purpose of this study is to examine the use of electronic cigarettes (e-cigarettes) among college students in Hangzhou, and to analyze the influencing factors of their intention to use e-cigarettes.
    METHODS: Using a stratified cluster sampling method, 775 students from two universities in Hangzhou were selected for an on-site questionnaire survey from March to April 2022. Adjusted logistic regression analysis was conducted on the influencing factors of use intention, based on innovation diffusion theory.
    RESULTS: Within our sample of college students, 16.5% of students had tried e-cigarettes; 6.32% had used e-cigarettes in the past month, and 8.0% had the intention to use e-cigarettes. There were significant differences in willingness to use e-cigarettes among different genders, economic status, smoking status of close friends around them, and their own use of tobacco and alcohol (p<0.05). The logistic regression model showed that the observability of e-cigarettes (AOR=1.28; p<0.05), personal factors (AOR=1.39; p<0.05), and social systems (AOR=1.63; p<0.05), were all influencing factors of intention to use e-cigarettes.
    CONCLUSIONS: College students in Hangzhou have a high intention to use e-cigarettes, and the impacts of the product itself, individual characteristics and the living environment are crucial. It is necessary to strengthen the promotion of tobacco knowledge at the social and family levels to reduce the occurrence of vaping.

    在这项工作中,我们建议使用类似量子的模拟器概念来研究与NP难题解决方案相关的社会过程。该模拟器基于我们最近在社交网络社区中的信息级联增长和回声室形成框架中提出的solaser模型。模拟器与我们在A和D级(超辐射)激光极限中检查的随机激光方法有关。决策代理的新型网络强制协同性参数,可以作为焊料模拟的结果来测量,被引入并为社会制度辩护。讨论了复杂网络中的创新扩散,这是我们建议的可能影响之一。
    In this work, we suggest a quantum-like simulator concept to study social processes related to the solution of NP-hard problems. The simulator is based on the solaser model recently proposed by us in the framework of information cascade growth and echo chamber formation in social network communities. The simulator is connected with the random laser approach that we examine in the A and D-class (superradiant) laser limits. Novel network-enforced cooperativity parameters of decision-making agents, which may be measured as a result of the solaser simulation, are introduced and justified for social systems. The innovation diffusion in complex networks is discussed as one of the possible impacts of our proposal.

    新冠肺炎大流行极大地改变了全球信息共享和处理的方式。COVID-19大流行深刻影响了信息全球化,导致通信的变化,信息传播,和技术。本文研究了与流行病相关的不确定性对事实上的信息全球化指数的影响(基于高科技出口的度量,国际专利,和使用的互联网带宽)。本文使用了1990年至2020年18个中欧和东欧(CEE)国家的面板数据集。结果表明,与流行病相关的不确定性会对中东欧经济体的信息全球化水平产生负面影响。这些发现在利用不同的估计技术和考虑北约成员中东欧国家方面是稳健的。
    The Covid-19 pandemic has dramatically changed how information is shared and processed worldwide. The COVID-19 pandemic has profoundly affected the globalization of information, causing shifts in communication, information dissemination, and technology. This paper investigates the impact of pandemics-related uncertainty on the index of de facto informational globalization (the measure based on high-technology exports, international patents, and used internet bandwidth). The paper uses the panel dataset of 18 Central and Eastern European (CEE) countries from 1990 to 2020. The results indicate that pandemics-related uncertainty negatively affects the informational globalization level in the CEE economies. The findings are robust in utilizing different estimation techniques and considering NATO member CEE countries.

    为加快智慧农业发展,实现农业绿色转型,介绍了前景理论与演化博弈理论的耦合。构建了农民合作社采用智能喷雾技术的两方进化博弈模型,根据复制动态方程分析农民合作社的演化和政府策略选择及其影响因素,并通过Matlab软件进行数值仿真实验。结果表明,农户合作社采用智能喷雾技术和政府对补贴的选择是该进化系统的两个最优稳定状态。政府的补贴政策可以有效刺激农民合作社采用智能喷雾技术,但是当政府补贴系数大于或等于70%时,政府和农民合作社的决策演变是不稳定的。农民对农药危害认识的提高,农民合作社的经营规模,优质农产品的价格,农民合作社对利润和损失的敏感性有助于智能喷雾技术的推广,智能喷雾技术的损伤概率具有一定的抑制作用。
    In order to accelerate the development of smart agriculture and realize the green transformation of agriculture, the coupling of prospect theory and evolutionary game theory is introduced. Construct a two-party evolutionary game model for the adoption of intelligent spray technology in farmers\' cooperatives, analyze the evolution of farmers\' cooperatives and government strategy selection and its influencing factors according to the replication dynamic equation, and conduct numerical simulation experiments through Matlab software. The results show that the adoption of intelligent spray technology by farmers\' cooperatives and the government\'s choice of subsidies are the two optimal stable states of the evolutionary system. The government\'s subsidy policy can effectively stimulate farmers\' cooperatives to adopt intelligent spray technology, but when the government subsidy coefficient is greater than or equal to 70%, the decision-making evolution of the government and farmers\' cooperatives is unstable. The increase in farmers\' awareness of pesticide hazards, the scale of operation of farmers\' cooperatives, the price of high-quality agricultural products, and the sensitivity of farmers\' cooperatives to profits and losses contribute to the promotion of intelligent spray technology, and the damage probability of intelligent spray technology has a restraining effect.

    背景:在2019年冠状病毒病(COVID-19)大流行之前,创新远程保健围产期护理模式的研究显示,在接受虚拟视频和当面访视相结合的组之间,临床结局和感知的护理质量相似.然而,这些研究主要包括怀特,讲英语的参与者,排除那些在经济上被剥夺公民权或不会说英语的人。这项定性研究的目的是描述围产期患者和提供者在COVID-19大流行急性期期间和之后的远程医疗经验,以告知未来利用远程医疗来推动高质量的交付,可访问,以及向不同社区提供公平的围产期护理。
    方法:这项描述性定性研究包括了14名患者和17名提供者的目的样本,他们在2020年3月至2022年4月期间通过认证的护士-助产实践或护士-家庭伙伴关系护理模式通过远程健康接受或提供围产期护理。最大变异抽样提供了基于种族的多样化人口,种族,和乡村。研究人员进行了两轮半结构化访谈,重点是了解社会和地理环境。
    结果:通过归纳分析确定了六个主题:(1)远程医疗的意外优势,(2)患者赋权,(3)提供者对不利结果的恐惧,(4)关注公平照顾,(5)增强远程健康体验的策略,(6)解决围产期远程保健问题的策略。患者赞赏访问的便利性增加和成本降低,这导致了更少的错过约会。医疗保健提供者在远程医疗中看到了巨大的机会,但对语言障碍或资源有限的患者的可及性表示担忧。
    结论:这项研究提供了对持续远程医疗利用的优先事项的见解,重点是提供公平的围产期护理。而不是回到COVID-19大流行之前的做法,这种做法是由长期的惯例和感知的局限性形成的,鼓励提供商利用远程医疗的快速创新来建立更有效的,公平,以及以患者为中心的围产期护理方法。
    BACKGROUND: Prior to the coronavirus disease 2019 (COVID-19) pandemic, studies of innovative telehealth perinatal care models showed similar clinical outcomes and perceived quality of care between groups receiving a combination of virtual video and in-person visits. However, these studies included primarily White, English-speaking participants, excluding those who were economically disenfranchised or did not speak English. The purpose of this qualitative study was to describe perinatal patients\' and providers\' experiences with telehealth during and after the acute phase of the COVID-19 pandemic to inform future utilization of telehealth to drive the delivery of high-quality, accessible, and equitable perinatal care to diverse communities.
    METHODS: This descriptive qualitative study included a purposive sample of 14 patients and 17 providers who received or provided perinatal care via telehealth in either a certified nurse-midwifery practice or the nurse-family partnership care model between March 2020 and April 2022. Maximum variation sampling offered a diverse population based on race, ethnicity, and rurality. Researchers conducted 2 rounds of semistructured interviews with a focus on understanding social and geographic context.
    RESULTS: Six themes were identified through inductive analysis: (1) unexpected advantages of telehealth, (2) patient empowerment, (3) providers\' fear of adverse outcomes, (4) concern for equitable care, (5) strategies to enhance the telehealth experience, and (6) strategies to address access to perinatal telehealth. Patients appreciated the increased ease and reduced cost of accessing visits, which led to fewer missed appointments. Health care providers saw great opportunity in telehealth but expressed concerns about accessibility for patients with language barriers or limited resources.
    CONCLUSIONS: This study provides insight into priorities for continued telehealth utilization focused on providing equitable access to perinatal care. Rather than returning to practices from before the COVID-19 pandemic formed from longstanding routines and perceived limitations, providers are encouraged to capitalize on the rapid innovations in telehealth to build a more effective, equitable, and patient-centered approach to perinatal care.

    护士经常创新以应对运营故障,法规,程序,和/或其他阻止他们提供高质量患者护理的工作流程障碍。不幸的是,大多数护士创新不会传播到更广泛的受众,剥夺其他护士利用已经在其他地方开发的解决方案。从社会和福利的角度来看,这种扩散不足是有问题的。本文的目的是了解如何减少护士创新的扩散不足。
    我们对荷兰最大的学术医院的医疗创客空间进行了定性案例研究。该医疗创客空间报告了异常高的护士创新扩散率。我们的数据收集包括现场观察,档案数据,辅助数据,对主要线人进行了15次深入采访。定性编码程序以及演绎推理和归纳推理的组合用于分析数据。
    我们的数据显示,组织,监管,和市场壁垒阻止护士以预期的方式进一步发展和传播他们的创新。也就是说,因为护士期望将最初的解决方案转变为可以与他人共享的创新将太耗时和困难,他们不会继续进一步发展。我们研究的医疗创客空间通过开发一个主要接管创新和扩散过程的创新生态系统来充分解决这个问题。
    我们提供了一个医疗创客空间,和更广泛意义上的创新支持系统,可以设计为更充分地解决护士创新-扩散差距。我们确定的实际解决方案的两个主要要素是:(1)支持系统应促进其他人可以领导创新的发展和传播;(2)支持系统应促进参与者将其功能专长整合到创新生态系统中。我们有两个理论贡献。首先,我们有助于从心理学角度理解护士创新-扩散过程中的障碍.第二,我们发现,生态系统的观点有利于发展扩散更频繁发生的创新支持系统。
    Nurses frequently innovate in response to operational failures, regulations, procedures, and/or other workflow barriers that prevent them from delivering high-quality patient care. Unfortunately, most nurse innovations do not diffuse to a broader audience, depriving other nurses from taking advantage of solutions that have already been developed elsewhere. This under-diffusion is problematic from a societal and welfare point of view. The goal of this paper is to understand how diffusion shortage of nurse innovations can be reduced.
    We develop a qualitative case study of a medical makerspace at the largest academic hospital in the Netherlands. This medical makerspace reported unusually high rates of nurse innovation diffusion. Our data collection includes on-site observations, archival data, secondary data, and fifteen in-depth interviews with key informants. Qualitative coding procedures and a combination of deductive and inductive reasoning are used to analyze the data.
    Our data show that personal, organizational, regulatory, and market barriers prevent nurses from further developing and diffusion their innovations in an anticipatory manner. That is, because nurses expect that transforming an initial solution into an innovation that can be shared with others will be too time consuming and difficult they do not proceed with the further development. The medical makerspace that we investigated adequately addresses this problem by developing an innovation ecosystem that largely takes over the innovation and diffusion process.
    We provide a concrete example of how a medical makerspace, and innovation support systems in a broader sense, can be designed to more adequately address the nurse innovation-diffusion gap. The two main elements of the practical solution that we identified are: (1) Support systems should facilitate that others may lead the development and diffusion of innovations and (2) The support system should promote that actors integrate their functional specializations within an innovation ecosystem. We make two theoretical contributions. First, we contribute to understanding barriers in the nurse innovation-diffusion process from a psychological point. Second, we identified that an ecosystem perspective is beneficial to develop innovation support systems in which diffusion occurs more often.

    Efforts to reduce global greenhouse gas emissions have had limited success. For many, the hopes rest on new energy innovations to advance the energy transition process. In this paper, we develop a Responsible Research and Innovation (RRI) base indicator system to steer the design of innovations in the field of energy transition innovations and, thus, improve social acceptance of these innovations. We propose a guideline for its application to assist R&D performing organizations and funding organizations in the design, selection, and communication of research proposals. The indicator system is intended to promote early integration of environmental and social aspects, support the formation of teams aware of the different responsibility aspects of innovation, and monitor progress in regard to relevant RRI dimensions.

    本研究调查了中国十四五规划(2021-2025年)背景下可再生能源和不可再生能源对碳排放的影响。该计划强调“双重控制”战略,即同时设定能源消耗限制和降低GDP(国内生产总值)的能源强度,以实现五年计划的目标。使用1990年至2022年中国能源和宏观经济信息的综合数据集,我们进行了Granger因果关系分析,以探讨能源与空气污染水平之间的关系。我们的发现揭示了一种单向联系,其中可再生能源有助于减少空气污染,而不可再生能源导致增加。尽管政府对可再生能源的投资,我们的结果表明,中国经济仍然严重依赖传统能源(例如,化石燃料)。这项研究是对中国背景下能源使用与碳排放之间相互作用的首次系统研究。我们的研究结果为旨在促进碳中和和推动政府和行业技术进步的政策和市场战略提供了宝贵的见解。
    This study investigates the impact of renewable and non-renewable energy sources on carbon emissions in the context of China\'s 14th Five-Year Plan (2021-2025). The plan emphasises a \"Dual-control\" strategy of simultaneously setting energy consumption limits and reducing energy intensity for GDP (gross domestic product) in order to meet the targets of the five-year plan. Using a comprehensive dataset of Chinese energy and macroeconomic information spanning from 1990 to 2022, we conduct a Granger causality analysis to explore the relationship between energy sources and the level of air pollution. Our findings reveal a unidirectional link, wherein renewable energy contributes to a reduction in air pollution, while non-renewable energy sources lead to an increase. Despite the government\'s investment in renewable energy, our results show that China\'s economy remains heavily reliant on traditional energy sources (e.g., fossil fuels). This research is the first systematic examination of the interplay between energy usage and carbon emissions in the Chinese context. Our findings provide valuable insights for policy and market strategies aimed at promoting carbon neutrality and driving technological advancements in both government and industries.
