    一个健康致力于维持和促进人类之间的动态平衡,动物,和环境。自2013年以来,它在全球范围内取得了长足的发展。这篇综述旨在概括一个健康的历史,以及绘制其未来轨迹。在“一个健康”原则下建立了许多研究机构,目前正在进行一些务实的项目。虽然巩固基础教育势在必行,需要进一步的政策支持来培养“单一健康”范式。在政治层面确定研究方向对于提供实际应用所需的技术支持是必要的。“一个健康”的未来设想了一种全面的初级预防方法,利用开放和共享的数据集,以及真实世界的调查和访谈。这种综合方法包含在一次健康交付的概念中。在这个阶段,一次健康交付需要建立一个系统的框架,侧重于跨学科的整合和沟通,并培训具有完整实践技能的研究人员。
    One Health is dedicated to maintaining and fostering a dynamic balance among humans, animals, and the environment. Since 2013, it has seen considerable developments globally. This review aims to encapsulate the history of One Health, as well as chart its future trajectory. Numerous research institutions founded under the principles of One Health have been established, and several pragmatic projects are currently underway. While it is imperative to solidify foundational education, further policy support is required to cultivate the One Health paradigm. Identifying research directions at a political level is necessary to provide the technical support needed for practical application. The future of One Health envisions a comprehensive approach to primary prevention, the utilization of open and shared data sets, as well as real-world surveys and interviews. This integrated approach is encapsulated in the concept of One Health Delivery. At this stage, One Health Delivery needs to build a systematic framework that focuses on integrating and communicating across disciplines and training researchers with complete practical skills.

    运动员在比赛中走神有积极和消极的影响。这项研究的目的是探讨这些双向效应的原因。
    我们从中国招募了51名运动员参加半结构化的面试,在面试中我们探讨了他们在比赛中走神的经历。运用扎根理论结合系统思维完成数据分析和理论构建。
    结果表明,思维游移对运动表现的影响受“思维游移源”的动态影响,“\”竞争焦虑,“\”内容的心灵徘徊,\"\"注意力资源\"和\"注意力控制,“导致我们发展了运动表现中的思维游移理论(MWSP)。“上述因素决定了思维游移是如何发生的,以及它如何影响竞争。
    尽管在比赛过程中发生的精神错乱具有积极的影响,其负面影响不容忽视,这可能导致运动员输掉比赛(成本高于福利)。讨论了旨在减轻思想游荡的负面影响和促进积极影响的潜在策略。
    UNASSIGNED: Athletes\' mind wandering during competition has positive and negative effects. The purpose of this study was to explore the reason for these bidirectional effects.
    UNASSIGNED: We recruited 51 athletes from China to take part in semi-structured interviews in which we explored their experiences of mind wandering in competition. We used grounded theory combined with systems thinking to complete the data analysis and theoretical construction.
    UNASSIGNED: Results showed that the influence of mind wandering on sporting performance was dynamically influenced by \"mind wandering source,\" \"competition anxiety,\" \"content of mind wandering,\" \"attentional resources\" and \"attentional control,\" resulting in our development of the theory of \"mind wandering in sporting performance (MWSP).\" The above factors determine how mind wandering occurs and how it affects the competition.
    UNASSIGNED: Although the occurrence of mind wandering during competition has positive effects, its negative effects cannot be ignored, which may lead to athletes losing the race (costs over benefits). Potential strategies focusing on the mitigation of negative effects and promotion of positive effects of mind wandering are discussed.

    随着对“碳中和”的追求势头强劲,强调低碳解决方案,强调节能和资源再利用,给传统的废水处理方法带来了新的挑战。准确评估城市给排水系统的碳排放,污水处理厂,建立碳中和运行模式已成为未来污水处理的重点。遗憾的是,有限的研究致力于碳核算和废水处理碳中和策略的发展。在这次审查中,为了促进全面的碳核算,我们最初认识到污水处理过程中的直接和间接碳排放源。然后,我们概述了几种主要的碳会计方法,并提出了碳会计框架。此外,我们提倡系统的观点,强调在废水处理中实现碳中和超出了废水处理厂的界限。我们评估了工厂内部和外部的当前技术措施,这些措施有助于实现碳中和操作。鼓励应用智能算法对废水处理过程进行多方面的监测和控制至关重要。支持资源和能源循环利用也至关重要,人们认识到协同废水处理技术的好处。我们提倡系统的,多层次的规划方法,考虑了广泛的因素。我们的目标是为碳中和框架内水环境管理的实际实施提供有价值的见解和支持,并促进可持续的社会经济发展,并为更加对环境负责的未来做出贡献。
    As the pursuit of \"carbon neutrality\" gains momentum, the emphasis on low-carbon solutions, emphasizing energy conservation and resource reuse, has introduced fresh challenges to conventional wastewater treatment approaches. Precisely evaluating carbon emissions in urban water supply and drainage systems, wastewater treatment plants, and establishing carbon-neutral operating models has become a pivotal concern in the future of wastewater treatment. Regrettably, limited research has been devoted to carbon accounting and the development of carbon-neutral strategies for wastewater treatment. In this review, to facilitate comprehensive carbon accounting, we initially recognizes direct and indirect carbon emission sources in the wastewater treatment process. We then provide an overview of several major carbon accounting methods and propose a carbon accounting framework. Furthermore, we advocate for a systemic perspective, highlighting that achieving carbon neutrality in wastewater treatment extends beyond the boundaries of wastewater treatment plants. We assess current technical measures both within and outside the plants that contribute to achieving carbon-neutral operations. Encouraging the application of intelligent algorithms for the multifaceted monitoring and control of wastewater treatment processes is paramount. Supporting resource and energy recycling is also essential, as is recognizing the benefits of synergistic wastewater treatment technologies. We advocate a systematic, multi-level planning approach that takes into account a wide range of factors. Our goal is to offer valuable insights and support for the practical implementation of water environment management within the framework of carbon neutrality, and to advance sustainable socio-economic development and contribute to a more environmentally responsible future.

    UNASSIGNED:系统思维是医学生最重要的思维技能之一。大多数研究都集中在设计技术丰富的学习环境,通常需要几周或几个月的时间才能实现。然而,COVID-19健康危机的发生不允许长时间实施课堂干预。如何在完全在线的环境中支持学生的系统思考仍然是一个问题。这项研究调查了鼓励学生在异步讨论论坛上提出问题是否支持他们的系统思维发展。
    UNASSIGNED:22名低年级学生参加了这项研究。我们比较了当学生被鼓励在一个单元的异步讨论论坛中提问时,他们是否以及如何开发系统思维,以及使用传统方法的另一个单元。本研究采用了多种分析方法,包括,社会网络分析,认知网络分析,推断统计分析和定性分析。
    UNASSIGNED:定量结果表明,与传统教学单元相比,所有学生的系统思维都得到了改善,其中领导者学生的进步最大。对学生讨论帖子的进一步分析建议,领导者学生提出了高系统思维水平的问题,并提供了高水平的回答。认知网络分析揭示了领导者是如何,常规和外围学生从事发起问题和提供不同的回答。
    UNASSIGNED:本研究提供了方法学和实践贡献。方法上,这项研究将网络分析的现有应用方法扩展到了其原始的职前教师培训环境之外;实际上,本研究为从业者提供了支持学生异步论坛讨论的策略。
    UNASSIGNED: Systems thinking is one of the most important thinking skills for medical students. Most of the studies focused on designing technological-rich learning environments which usually take several weeks or months to implement. However, the occurring of COVID-19 health crisis does not allow extensive period of time to implement classroom interventions. How to support students\' systems thinking in fully online environments remains an issue. This study examines if encouraging students initiating questions on asynchronous discussion forum supports their systems thinking development.
    UNASSIGNED: Twenty-two junior students participated in this study. We compared if and how students developed systems thinking when they were encouraged asking questions in asynchronous discussion forums in one unit with another unit in which traditional method was used. Multiple analytical methods were applied in this study, including, social network analysis, epistemic network analysis, inferential statistical analysis and qualitative analysis.
    UNASSIGNED: Quantitative results showed that all students improved systems thinking compared with traditional teaching unit among which leader students improved most. Further analysis on students\' discussion posts suggested leader students asked high systems thinking level questions and provided high level responses. Epistemic network analysis unpacked how leader, regular and peripheral students engaged in initiating questions and providing responses differently.
    UNASSIGNED: This study provides methodological and practical contributions. Methodologically, this study extends prior methods of applying network analysis beyond its original preservice teacher training contexts; practically, this study provides strategies to practitioners to support students\' asynchronous forum discussions.

    化学污染危机严重威胁着全球人类和环境的健康。为了应对这一挑战,最近建议建立一个总体的国际科学政策机构。我们强烈支持这一倡议,因为我们意识到人类可能已经在行星边界内离开了安全的操作空间,以容纳包括化学污染在内的新实体。立即行动至关重要,需要有健全的科学知识和数据,由一个总体的科学政策接口机构汇编和严格评估。这样一个机构的主要挑战是(i)促进全球知识生产,超出数据丰富区域的影响和治理(例如,欧洲和北美),(ii)涵盖全部危险化学品,混合物和废物,(iii)遵循单一健康的观点,考虑到化学品和废物对生态系统和人类健康构成的风险,和(iv)努力基于系统思维进行面向解决方案的评估。基于全球范围内紧急行动的多种证据,我们呼吁科学家和从业人员动员其科学网络,并加强与各国政府的科学政策互动,以支持关于建立基于科学知识的政府间机构的谈判,以解释对人类和环境健康的预期益处。
    The chemical pollution crisis severely threatens human and environmental health globally. To tackle this challenge the establishment of an overarching international science-policy body has recently been suggested. We strongly support this initiative based on the awareness that humanity has already likely left the safe operating space within planetary boundaries for novel entities including chemical pollution. Immediate action is essential and needs to be informed by sound scientific knowledge and data compiled and critically evaluated by an overarching science-policy interface body. Major challenges for such a body are (i) to foster global knowledge production on exposure, impacts and governance going beyond data-rich regions (e.g., Europe and North America), (ii) to cover the entirety of hazardous chemicals, mixtures and wastes, (iii) to follow a one-health perspective considering the risks posed by chemicals and waste on ecosystem and human health, and (iv) to strive for solution-oriented assessments based on systems thinking. Based on multiple evidence on urgent action on a global scale, we call scientists and practitioners to mobilize their scientific networks and to intensify science-policy interaction with national governments to support the negotiations on the establishment of an intergovernmental body based on scientific knowledge explaining the anticipated benefit for human and environmental health.

    The use of traditional and complementary medicines (TM/CMs) has become an increasingly popular part of healthcare and self-care practices across the world. While the benefits and risks of many TM/CMs are yet to be fully evaluated, their prevalent use without consistent oversight has not been fully addressed by the public health sector. Pharmacists play an integral role in contributing to public health. Discussion about integrating TM/CMs into the professional practice of the pharmacist began over two decades ago. Nevertheless, TM/CMs are predominantly managed as \"retail products\" and are not integrated into pharmaceutical care and practice. While some isolated measures towards integration have been proposed, there remains no consensus on how to deliver pharmaceutical care in a coordinated, systematic manner. Systems thinking approaches are needed to formulate and implement strategies that change pharmacists\' practice related to TM/CMs. Such approaches will ultimately reduce risk, optimize patient care, and result in better health outcomes.

    Hydrothermal liquefaction (HTL) is one of the most promising platforms to valorize diverse biomass. Yet, a large amount of wastewater is produced containing a large amount of recalcitrant substances. Valorization of the refractory wastewater by biological systems to recapture organic matter and nutrients is not only clearly beneficial for the environment but also good for energy recovery. To this end, this study reviews the valorization of HTL wastewater via biological systems from many points of view, starting with the brief characterization of wastewater derived from HTL of diverse biomass. The fundamentals, pros and cons, and the most recent outcomes of numerous biological systems are comprehensively demonstrated with emphasis on their combinations. We then use a systems-thinking concept to shed light on a procedural model exhibiting a new perspective to consolidate the utilization of these systems. Finally, this review elucidates the future perspectives of HTL wastewater valorization.

    The transmission of infectious diseases is a dynamic process determined by multiple factors originating from disease pathogens and/or parasites, vector species, and human populations. These factors interact with each other and demonstrate the intrinsic mechanisms of the disease transmission temporally, spatially, and socially. In this article, we provide a comprehensive perspective, named as systems thinking, for investigating disease dynamics and associated impact factors, by means of emphasizing the entirety of a system\'s components and the complexity of their interrelated behaviors. We further develop the general steps for performing systems approach to tackling infectious diseases in the real-world settings, so as to expand our abilities to understand, predict, and mitigate infectious diseases.
