    尽管越来越多的证据突出了运动技巧的个性,运动学习的主要模型,特别是在收购阶段,继续强调泛化,独立于人的方法。生物力学研究,再加上机器学习方法,已经证明了个人表现出的运动技术的独特性。然而,这些证据主要与已经稳定的运动技术有关,在周期性的日常活动中尤其明显,例如步行,跑步,或者骑自行车,以及专家级的运动。这项研究旨在评估全身运动中的个性假设,这需要在习得阶段开始时新手参与者之间进行复杂的协调和力量。
    在主题内设计中,16名高度活跃的男性参与者(平均年龄:23.1±2.1岁),学习任务中的所有绝对新手(即,奥运会举重的力量抓举),参加了随机抓举学习比赛。这些回合包括跨各种运动学习模型的36项试验:差异学习情境干扰(serial,sCIL;和阻塞,bCIL),重复学习。从每个运动学习模型回合后进行的三个标准化抓举试验中收集了运动学和动力学数据。将时间连续数据输入到线性支持向量机(SVM)。我们对两个分类任务进行了分析:参与者和运动学习模型。
    与运动学习模型分类相比,支持向量机分类显示出明显优于参与者的分类,平均预测准确率为78%(在跨褶皱的45个测试试验中平均约35个)和27.3%(在跨褶皱的36个测试试验中平均约9个)。在特定的折叠和输入组合中,准确率分别为91%和38%。
    方法,在未来研究的背景下,讨论了选择合适的数据预处理方法和确定SVM数据输入的最佳组合的关键作用。我们的发现为在奥运会举重力量抓举的早期阶段,在运动技术中运动学习模型的个性优势提供了初步支持。
    UNASSIGNED: Despite the growing body of evidence highlighting the individuality in movement techniques, predominant models of motor learning, particularly during the acquisition phase, continue to emphasise generalised, person-independent approaches. Biomechanical studies, coupled with machine learning approaches, have demonstrated the uniqueness of movement techniques exhibited by individuals. However, this evidence predominantly pertains to already stabilised movement techniques, particularly evident in cyclic daily activities such as walking, running, or cycling, as well as in expert-level sports movements. This study aims to evaluate the hypothesis of individuality in whole-body movements necessitating intricate coordination and strength among novice participants at the very beginning of an acquisition phase.
    UNASSIGNED: In a within-subject design, sixteen highly active male participants (mean age: 23.1 ± 2.1 years), all absolute novices in the learning task (i.e., power snatch of Olympic weightlifting), participated in randomised snatch learning bouts. These bouts comprised 36 trials across various motor learning models: differential learning contextual interference (serial, sCIL; and blocked, bCIL), and repetitive learning. Kinematic and kinetic data were collected from three standardised snatch trials performed following each motor learning model bout. The time-continuous data were input to a linear Support Vector Machine (SVM). We conducted analyses on two classification tasks: participant and motor learning model.
    UNASSIGNED: The Support Vector Machine classification revealed a notably superior participant classification compared to the motor learning model classification, with an averaged prediction accuracy of 78% (in average ≈35 out of 45 test trials across the folds) versus 27.3% (in average ≈9 out of 36 test trials across the folds). In specific fold and input combinations, accuracies of 91% versus 38% were respectively achieved.
    UNASSIGNED: Methodically, the crucial role of selecting appropriate data pre-processing methods and identifying the optimal combinations of SVM data inputs is discussed in the context of future research. Our findings provide initial support for a dominance of individuality over motor learning models in movement techniques during the early phase of acquisition in Olympic weightlifting power snatch.

    这项研究旨在阐明每个自由肢体近端关节的相对垂直动量的动力学及其对跨栏间隙起飞时质心高度增加的贡献,以及它们与起飞变量的关系。十三名男子跨栏运动员在其质量中心的高度清除了一个障碍,他们的尝试是用六台高速摄像机拍摄的。跨栏高度为96.54±2.63cm(身高的55.35±0.29%)。接近距离设定为15m,并且由每个跨栏者在10-50cm的范围内调整,以便在起飞前不涉及任何明显的步长调整。组合的自由肢相对垂直动量趋于增加,直到中间支撑,并一直保持到脚趾离开。起飞时脚趾处的全身垂直动量越小,起飞时铅腿的相对垂直动量增加越小,起飞速度越高,支持时间越短,减速度越小。触地过程中前摆臂的相对垂直动量越高,起飞时自由臂和前摆臂的组合相对垂直动量增加越小。减速度越小。总之,跨栏运动员应通过抑制前腿和前摆臂的相对垂直动量的增加来减少起飞时全身垂直动量的增加。
    This study aimed to clarify the kinetics of the relative vertical momentum to the proximal joint of each free limb and their contribution to the increase in the centre of mass height at the take-off of hurdle clearance, as well as their relationship with take-off variables. Thirteen male hurdlers cleared one hurdle at the height of their centre of mass, and their attempts were filmed using six high-speed cameras. The hurdle height was 96.54 ± 2.63 cm (55.35 ± 0.29% of body height). The approach distance was set at 15 m and adjusted by each hurdler in the range of 10-50 cm so as not to involve any noticeable step length adjustment before the take-off. The combined free limb relative vertical momentum tended to increase until mid-support and was maintained until the toe off. The smaller the whole-body vertical momentum at the toe off and the increase in relative vertical momentum of the lead leg during the take-off, the higher the take-off velocity, the shorter the support time, and the smaller the deceleration. The higher the relative vertical momentum of the forward swing arm during touchdown and the smaller the relative vertical momentum increase of the combined free limb and the forward swing arm during the take-off, the smaller the deceleration. In conclusion, hurdlers should reduce the increase in whole-body vertical momentum at the take-off by suppressing the increase in relative vertical momentum of the lead leg and the forward swing arm.

    有效的机构协调和沟通是社区抗灾能力和成功执行减少灾害风险(DRR)战略的重要决定因素。一些国际协议赞同采用合并,去中心化,参与式方法管理水文气象灾害。然而,地方政府制定和实施有效减少灾害风险战略的能力仍然不一致,也相对未知。为了实现可持续的经济发展,纳米比亚制定了DRR立法框架,并招募了一个中央机构来执行减轻灾害破坏和建设国家复原力的战略政策。本研究采用定性案例研究方法,以评估中央灾害风险管理机构在建立有效的机构协调和沟通结构以成功实施洪水预警系统方面的作用。根据其立法授权,该研究对机构在DRR精简方面的经验进展进行了分层背景的描述。
    该研究确定了官僚主义,机构能力有限,资金不足以及响应和救济优先次序是对系统有效性的主要挑战。它为更好的机构协调和沟通提供了指令,以减少未来的伤害。
    An effective institutional coordination and communication are essential determinants of community disaster resilience capacities and successful execution of disaster risk reduction (DRR) strategies. Several international agreements endorse adopting consolidated, decentralised, participatory approaches to manage hydrometeorological hazards. Yet, the capacity of local governments to develop and implement effective disaster risk reduction strategies remains inconsistent and relatively unknown. In its quest to achieve sustainable economic development, Namibia has developed a DRR legislative framework and enlisted a central body to execute the strategic policy for disaster disruption mitigation and national resilience building. This study adopts a qualitative case study approach to assess the role of the central disaster risk management institution in establishing effective institutional coordination and communication structures for successful flood early warning system operations. Based on its legislative mandate, the study presents a hierarchically contextualised account of the institutions\' empirical progress in DRR streamlining.
    UNASSIGNED: The study identifies bureaucracy, limited institutional capacities, inadequate funding and response and relief prioritisation as major challenges to system efficacy. It provides directives for better institutional coordination and communication to reduce future harm.

    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.

    背景:三分之一的痴呆症患者(PLWD)的护理高度分散(即护理遍布许多没有主导提供者的门诊提供者)。目前尚不清楚接受零散护理的PLWD及其护理人员是否认为所涉及的提供者之间的沟通存在差距,以及任何此类差距是否被视为良性不便或具有临床意义,导致不良事件。我们试图确定提供者之间沟通(协调)中感知到的差距的频率以及归因于协调不良的自我报告不良事件的频率。
    方法:我们在2022-2023年在纽约的Medicare责任护理组织(ACO)的背景下进行了一项横断面研究。我们包括了归于ACO的PLWD,在过去的一年中,由于索赔而出现了零散的护理(反向Bice-Boxerman指数≥0.86),并在一项实用的护理管理临床试验中。我们使用现有的调查工具来确定对护理协调的看法和对四个不良事件的看法(重复测试,药物-药物相互作用,急诊部门的访问,和医院入院)。ACO护理经理通过电话收集数据,使用临床判断来确定每个调查受访者是患者还是护理人员.我们使用描述性统计来总结结果。
    结果:在167个合格的PLWD中,调查完成97项(58.1%)。其中,88(90.7%)报告有>1次门诊就诊和>1次门诊服务提供者,因此存在护理协调差距的风险,并纳入分析。其中,23名患者(26.1%)和64名护理人员(72.7%),缺少一个受访者的角色。总的来说,57%的受访者表示在护理协调方面存在问题(或“差距”),分开,18%的人报告了不良事件,他们归因于护理协调差。
    结论:据报道,PLWD的护理协调差距非常普遍,通常被认为是危险的。
    BACKGROUND: One-third of people living with dementia (PLWD) have highly fragmented care (i.e., care spread across many ambulatory providers without a dominant provider). It is unclear whether PLWD with fragmented care and their caregivers perceive gaps in communication among the providers involved and whether any such gaps are perceived as benign inconveniences or as clinically meaningful, leading to adverse events. We sought to determine the frequency of perceived gaps in communication (coordination) among providers and the frequency of self-reported adverse events attributed to poor coordination.
    METHODS: We conducted a cross-sectional study in the context of a Medicare accountable care organization (ACO) in New York in 2022-2023. We included PLWD who were attributed to the ACO, had fragmented care in the past year by claims (reversed Bice-Boxerman Index ≥0.86), and were in a pragmatic clinical trial on care management. We used an existing survey instrument to determine perceptions of care coordination and perceptions of four adverse events (repeat tests, drug-drug interactions, emergency department visits, and hospital admissions). ACO care managers collected data by telephone, using clinical judgment to determine whether each survey respondent was the patient or a caregiver. We used descriptive statistics to summarize results.
    RESULTS: Of 167 eligible PLWD, surveys were completed for 97 (58.1%). Of those, 88 (90.7%) reported having >1 ambulatory visit and >1 ambulatory provider and were thus at risk for gaps in care coordination and included in the analysis. Of those, 23 respondents were patients (26.1%) and 64 were caregivers (72.7%), with one respondent\'s role missing. Overall, 57% of respondents reported a problem (or \"gap\") in the coordination of care and, separately, 18% reported an adverse event that they attributed to poor care coordination.
    CONCLUSIONS: Gaps in coordination of care for PLWD are reported to be very common and often perceived as hazardous.

    这项研究提出了两个简单的物理治疗计划,实施了五周,并显示出平衡的积极变化,协调,和运动技能在幼儿园与ASD。在健身房中进行物理治疗程序,并在带有平衡板和不稳定底座的智能板上进行游戏,以改善ASD儿童的身体状况。30名在特殊需要幼儿园就读的ASD儿童(4-6岁)被纳入研究。三个测试用于评估研究前后参与者的身体状况:改良的Berg平衡量表,不平衡协调样本,和Bruininks-Oseretsky运动能力测试(BOTMP)。由此产生的均值变化,根据每组的分数计算,显示在智能板上接受物理治疗的参与者的最大变化为1.58分。它表明,在智能板上玩游戏的机会激励患有ASD的孩子更加努力地工作;因此,这是一个简单和容易的方式让孩子们参与不同类型的体育锻炼。在接受健身房训练的组中获得了1.51的稍小的变化。然而,由于缺乏欲望和动力,对于患有ASD的孩子来说,在健身房工作在心理上更具挑战性。这两种方法都相对简单,易于在家中应用;因此,父母可以为改善儿童的身体状况做出重大贡献,并且可以成为帮助这些人进行日常生活活动的有效工具。
    This study presents two simple physiotherapy programs that were implemented for five weeks and showed positive changes in balance, coordination, and motor skills in kindergarteners with ASD. Physiotherapy programs in a gym and games on a smart board with balance plates and an unstable base were applied to improve the physical condition of children with ASD. Thirty children with ASD (4-6 years old) attending special needs kindergarten were enrolled in the study. Three tests were used to assess participants\' physical condition before and after the study: the modified Berg Balance Scale, the Imbalance Coordination Sample, and the Bruininks-Oseretsky Motor Proficiency Test (BOTMP). The resulting mean change, calculated from each group\'s scores, shows that the participants who received physical therapy sessions at the smart board had the greatest change of 1.58 points. It shows that the opportunity to play games on a smart board motivates children with ASD to work harder; therefore, it is a simple and easy way to engage children in different types of physical exercise. A slightly smaller change of 1.51 was obtained in the group that received gym sessions. However, working in the gym was more psychologically challenging for the children with ASD due to their lack of desire and motivation. Both methods are relatively simple and easy to apply at home; therefore, parents can make a significant contribution to improving children\'s physical condition and that can be an effective tool to assist these individuals with activities in daily life.

    OBJECTIVE: The Comprehensive Coordination Scale (CCS) is a valid, reliable scale for evaluating motor coordination, described as the ability to produce context-dependent movements of multiple body parts in both spatial and temporal domains in patients with chronic stroke. The aim of this study was to develop a Turkish version of the CCS that can be used to evaluate coordination in Parkinson\'s disease patients and to test its validity and reliability.
    METHODS: Thirty-four patients with Parkinson\'s disease (18 females, 16 males) with a mean age of 67.55± 10.93 years were included. The 9-Hole Peg Test (9 HPT), Timed Up and Go Test (TUG), Berg Balance Scale (BBS), Functional Reach Test (FRT), and Modified Hoehn and Yahr (H&Y) were administered to the patients.
    RESULTS: In the correlation analysis for convergent validity, the CCS-TR showed a moderate negative correlation with both the 9 HPT and the TUG test (r=-0.684 and -0.641, respectively). There were also moderate positive correlations observed between the CCS-TR and the FRT and BBS (r=0.607 and 0.657, respectively). The total CCS-TR had excellent intrarater reliability (ICC=0.99; 95 % CI: 0.98-0.99) and interrater reliability (ICC=0.90; 95 % CI: 0.81-0.95). The CCS-TR subscales had excellent intrarater reliability (ICC: range 0.98 from 0.99). For intrarater agreement, the ICC was 0.99, and for interrater agreement, the ICC was 0.90 (excellent agreement).
    CONCLUSIONS: The results of the present study indicate that the Turkish version of the CCS is a reliable and valid coordination scale that can be used in patients with Parkinson\'s disease.

    越来越多的患者提前出院,越来越多的患者有复杂的医疗保健需求,并在初级医疗保健部门接受护理。为了确保护理的有效协调和连续性,获取相关信息至关重要。我们从两个挪威城市报告说,在一个创新项目中,将他们的信息系统从纸质系统转移到数字协调系统。举办了讲习班和访谈,以解决这些考虑因素,创新过程中参与者的反思和困境。分析提供了三个主要主题,分别是:1)从纸质到数字概述的过渡;2)从单个患者信息过渡到患者群体的数字概述;3)从使用电话过渡到信息的数字交换。演员们必须克服几个挑战。然而,结果是,他们获得了符合情境的信息,从而提高了协调工作的效率和患者安全.
    More patients are being discharged early from hospital and increasing numbers of patients have complex health care needs and receive care in the primary health care sector. To ensure efficient coordination and continuity of care, access to relevant information is crucial. We report from two Norwegian municipalities that, during an innovation project, transferred their information system from a paper-based to a digital coordination system. Workshops and interviews were conducted to address the considerations, reflections and dilemmas of the actors involved during the innovation process. The analysis provided three main themes which were: 1) transition from paper-based to digital overviews; 2) transition from individual patient information to a digital overview of groups of patients; and 3) transition from use of telephone to digital exchange of information. The actors had to overcome several challenges. Nevertheless, the outcome was that they were provided with contextualised information enabling efficiency and patient safety in their coordination work.

    Covid-19大流行迫使全球公司将劳动力转移到在家工作[WFH]。公司现在正努力从办公室恢复工作[WFO],因为员工享受WFH的工作与生活平衡的显著好处。因此,许多公司正在采用一种混合模式,即员工部分在办公室工作,部分在家中工作。我们使用来自印度IT服务公司的独特而详细的数据,该数据包含对这三个工作环境中超过48,000名员工的创新活动的精确测量。我们的关键成果是员工提交的想法的数量和质量。基于事件研究设计,与WFO相比,WFH期间的想法数量没有变化,但是思想的质量受到了影响。在后来的混合时期,提交的想法数量下降了。在混合阶段,创新尤其受到团队的影响,这些团队在办公室或在家工作时没有很好地协调。我们的发现表明,远程和混合工作模式可能会抑制协作和创新。
    The Covid-19 pandemic forced firms globally to shift workforces to working from home [WFH]. Firms are now struggling to implement a return to working from the office [WFO], as employees enjoy the significant benefits of WFH for their work-life balance. Therefore many firms are adopting a hybrid model in which employees work partly from the office and partly from home. We use unique and detailed data from an Indian IT services firm which contains a precise measure of innovation activity of over 48,000 employees in these three work environments. Our key outcomes are the quantity and quality of ideas submitted by employees. Based on an event study design, the quantity of ideas did not change during the WFH period as compared to WFO, but the quality of ideas suffered. During the later hybrid period, the quantity of submitted ideas fell. In the hybrid phase innovation suffered particularly in teams which were not well coordinated in terms of when they worked at the office or from home. Our findings suggest that remote and hybrid work modes may inhibit collaboration and innovation.

    系鞋带这个看似简单的任务需要复杂的关节相互作用,肌肉,和神经通路,对研究协调复杂性的研究人员构成了巨大的挑战。用于测量协调行为的广泛接受的框架是Haken-Kelso-Bunz(HKB)模型。然而,该模型的一个重要限制是它缺乏对它经常建模的协调系统固有的多样化的可变性结构的解释。变异性是各种生物和物理系统中普遍存在的现象,它在健康的成年人身上发生了变化,老年人,和病理人群。这里,我们展示,无论是凭经验还是通过模拟,操纵协调运动的可变性会显着影响改变协调模式的能力-HKB模型的基本特征。我们的结果表明,同步双向协调,反映了健康的变异性状态,与其他变异性条件相比,可以促进协调运动的更早过渡。这表明,当运动具有健康的变异性时,适应性会增强。我们预计我们的研究表明调整HKB模型以包含变异性的必要性,特别是在神经成像等预测应用中,认知,技能发展,生物力学,和超越。
    The seemingly straightforward task of tying one\'s shoes requires a sophisticated interplay of joints, muscles, and neural pathways, posing a formidable challenge for researchers studying the intricacies of coordination. A widely accepted framework for measuring coordinated behavior is the Haken-Kelso-Bunz (HKB) model. However, a significant limitation of this model is its lack of accounting for the diverse variability structures inherent in the coordinated systems it frequently models. Variability is a pervasive phenomenon across various biological and physical systems, and it changes in healthy adults, older adults, and pathological populations. Here, we show, both empirically and with simulations, that manipulating the variability in coordinated movements significantly impacts the ability to change coordination patterns-a fundamental feature of the HKB model. Our results demonstrate that synchronized bimanual coordination, mirroring a state of healthy variability, instigates earlier transitions of coordinated movements compared to other variability conditions. This suggests a heightened adaptability when movements possess a healthy variability. We anticipate our study to show the necessity of adapting the HKB model to encompass variability, particularly in predictive applications such as neuroimaging, cognition, skill development, biomechanics, and beyond.
