    这项研究旨在研究非睡眠深度休息(NSDR)对身体和认知表现的影响,以及困倦,急性准备,recovery,压力,和身体活动参与者的情绪状态。共有65名身体活跃的参与者(42名男性,23名女性)被随机分为两组:一个实验组(NSDR,n=34),参与者完成了10分钟的NSDR干预,和一个对照组(CON,n=31),参与者被动地坐了10分钟。在每种情况发生前和10分钟后立即评估测试措施,包括完成手握力强度测力计测试和力板上的反运动跳跃测试。通过精神运动警觉任务(PVT-B)测量认知功能,还有一个西蒙任务测试,以及四份评估睡眠的问卷,recovery,和情绪状态。重要的组×时间相互作用有利于NSDR条件的握力,PVT-B期间的中位反应时间,和西蒙任务期间的准确度百分比。问卷答复表明,NSDR与身体准备的显着益处相关,情绪平衡,整体复苏,消极的情绪状态,整体应力,和张力相比CON(p<0.05)。NSDR干预措施可能是一项宝贵的战略,可以敏锐地提高整体福祉和准备水平。
    This study aimed to examine the effect of nonsleep deep rest (NSDR) on physical and cognitive performance, as well as sleepiness, acute readiness, recovery, stress, and mood state in physically active participants. A total of 65 physically active participants (42 male, 23 female) were randomly assigned into two groups: an experimental group (NSDR, n = 34), in which participants completed a 10-min NSDR intervention, and a control group (CON, n = 31), whereby participants sat passively for 10 min. Testing measures were assessed immediately pre and 10 min post each condition and comprised completing a hand grip strength dynamometer test and a countermovement jump test on force plates, cognitive function measures via a psychomotor vigilance task (PVT-B), and a Simon task test, along with four questionnaires to assess sleep, recovery, and mood state. A significant Group × Time interaction favored the NSDR condition for handgrip strength, median reaction time during the PVT-B, and accuracy percentage during the Simon task. Questionnaire responses demonstrated NSDR to be associated with significant benefits to physical readiness, emotional balance, overall recovery, negative emotional state, overall stress, and tension in comparison to CON (p < .05). The NSDR intervention could be a valuable strategy for acutely enhancing overall well-being and readiness.

    Workplace stress can affect forensic experts\' job satisfaction and performance, which holds financial and other implications for forensic service providers. Therefore, it is important to understand and manage workplace stress, but that is not simple or straightforward. This paper explores stress as a human factor that influences forensic expert decision-making. First, we identify and highlight three factors that mitigate decisions under stress conditions: nature of decision, individual differences, and context of decision. Second, we situate workplace stress in forensic science within the Challenge-Hindrance Stressor Framework. We argue that stressors in forensic science workplaces can have a positive or a negative impact, depending on the type, level, and context of stress. Developing an understanding of the stressors, their sources, and their possible impact can help forensic service providers and researchers to implement context-specific interventions to manage stress at work and optimize expert performance.

    陆军战斗体能测试(ACFT)用于评估潜在学员的军事准备水平。这项研究的目的是评估陆军预备役军官训练团(ROTC)计划实施的锻炼训练计划的有效性,以衡量ACFT的性能指标。
    方法:阿拉巴马大学伯明翰分校(UAB)项目的26名ROTC学员参加了这项研究。在8个月的时间里,ROTC学员每周三天在校园接受培训。训练以巡回训练的形式进行,每个参与者循环通过四个训练站中的每个(力量,Conditioning,核心,和耐力)每节15分钟(总训练时间为60分钟)。每个学员都评估了体重和身体成分以及ACFT的每个组成部分[最大死角提升(MDL),常备动力投掷(SPT),手动释放上推(HRP),sprint-drag-carry(SDC),腿折板/木板(LTK/PLK),和2英里跑步(2MR)]。在三个时间点评估每个变量(前,mid-,和培训后计划)。
    结果:时间点之间的2MR评分存在显着差异[F(2,50)=4.530,p=.016,η2=0.153],训练前和训练后的时间点之间存在显着差异(p=.02)。没有其他变量显示显着变化:体重(p=.741),体脂百分比(p=0.238),MDL(p=.061),SPT(p=.308),HRP(p=.126),SDC(p=0.132),LTK/PLK(p=0.583)。
    结论:这项研究的结果表明,使用的短期训练计划提高了2MR,但不是ACFT的其他组成部分在一个学年的过程中。
    The Army Combat Fitness Test (ACFT) is used to evaluate the fitness level of potential Cadets for military readiness. The purpose of this study was to evaluate the effectiveness of the exercise training program implemented by an Army Reserve Officers\' Training Corps (ROTC) program to gauge the performance metrics of the ACFT.
    METHODS: Twenty-six student Cadets of the ROTC at the University of Alabama at Birmingham (UAB) program participated in the study. Over an 8-month period, the ROTC Cadets trained on campus three days per week. Training was performed in a circuit training format and each participant cycled through each of the four training stations (Strength, Conditioning, Core, and Endurance) for 15 minutes each session (for a total training time of 60 minutes). Each Cadet had body mass and body composition assessed as well as each component of the ACFT [maximum dead lift (MDL), standing power throw (SPT), hand release push-up (HRP), sprint-drag-carry (SDC), leg tuck/plank (LTK/PLK), and 2-mile run (2MR)]. Each variable was evaluated at three time points (pre-, mid-, and post-training program).
    RESULTS: There was a significant difference in the 2MR score between time points [F(2,50) = 4.530, p = .016, η2 = 0.153] with a significant difference between time point at pre- and post-training (p = .02). No other variables displayed a significant change: body mass (p = .741), body fat percentage (p = .238), MDL (p = .061), SPT (p = .308), HRP (p = .126), SDC (p = 0.132), LTK/PLK (p = 0.583).
    CONCLUSIONS: The results of this study suggest that the short-term training program used improves 2MR, but not other components of the ACFT over the course of an academic year.

    侦察海上训练是故意困难的,确保毕业生具备在高风险军事职业专业成功运作所需的能力。大部分的培训减员是由于自愿退出和以前的研究已经确定了某些预测因素,如人口统计学,精神状态,和物理性能。虽然已经确定了训练减员的一些特征,仍然缺乏与个人档案相关的理解,更容易完成侦察训练。对侦察培训公司3,438名学员的回顾性调查数据进行了分析。调查与学员的军事招募历史和其他军事经验有关,先前的生活经验,运动体验,自我认同的人格特征和动机,以及自愿退出的原因,如果适用,以及物理性能指标。各种人口因素,自我报告的爱好,动机,水生体验,身体表现与侦察海洋训练课程的成功有关。自愿退出训练的受试者最常将精神压力和水生僵化作为原因,而较不常见的原因是身体和家庭原因。这些结果可能会提高培训成功率,但是需要更多的研究来了解观察到的受训者特征与精英战士训练成功之间的关系。
    Reconnaissance Marine training is deliberately difficult, to assure that graduates have the capabilities required to function successfully in the high-risk military occupational specialty. The majority of training attrition is due to voluntary withdrawal and previous research has identified certain predictive factors such as demographics, mental status, and physical performance. While some characteristics of training attrition have been identified, there is still a lack of understanding related to an individual\'s profile that is more apt to complete Recon training. Retrospective survey data was analyzed from 3,438 trainees within the Reconnaissance Training Company. Surveys were related to trainees\' military recruitment history and other military experience, prior life experience, athletic experience, self-identified personality characteristics and motivations, and reasons for voluntary withdrawal if applicable, as well as physical performance metrics. Various demographic factors, self-reported hobbies, motivations, aquatic experience, and physical performance were associated with success in Recon Marine training courses. Subjects who voluntarily withdrew from training most commonly cited mental stress and aquatic rigor as the reason and less commonly cited reasons were physical and family reasons. These results could potentially increase training success, but more research is needed to understand the relationships between the observed trainee characteristics and success in elite warfighter training.

    数字化水平的提高为石油和天然气行业的效率带来了重大机遇,但也可能导致新的风险和漏洞。根据行业的发展,挪威海洋工业局(HAVTIL)近年来一直致力于有针对性的知识开发和公司数字化计划的后续行动。本文探讨了通过HAVTIL对井作业中自动化系统的开发和使用进行审计而收集的数据。对数据的分析导致确定了与数字技术实施有关的五个主要主题。五个主要主题是组织复杂性,技术的跟进和实施,分析和文档,用户界面和报警和能力和培训。总的来说,结果支持人为因素和技术发展中的研究成果,指出在发展项目和业务中都缺乏对人为因素的关注。此外,本文介绍了如何跟进数字化计划,并根据行业当前的发展探讨了分析结果。
    为了调查自动化操作和人员表现,挪威海洋工业局(HAVTIL)进行了三项审核。这些审计已被用作案例研究和本文的基础。分析结果支持人为因素和技术开发领域的研究结果,指出在发展项目和业务中都缺乏对人为因素的关注。
    Increased levels of digitalisation present major opportunities for efficiency in the oil and gas industry but can also contribute to new risks and vulnerabilities. Based on developments in the industry, the Norwegian Ocean Industry Authority (HAVTIL) has in recent years pursued targeted knowledge development and follow-up of company\'s digitalisation initiatives. This paper explores data collected through HAVTIL\'s audits of the development and use of automated systems within well operations. The analysis of the data resulted in the identification of five main topics related to the implementation of digital technologies. The five main topics were organisational complexity, follow-up and implementation of technology, analysis and documentation, user-interface and alarms and competence and training. Overall, the results support research findings within human factors and technology development, pointing out that there is a lack of focus on human factors in both development projects and in operations. In addition, this paper provides insight into how digitalisation initiatives are followed-up and explores the results from the analysis in light of the current developments in the industry.
    To investigate automated operations and human performance, three audits were performed by the Norwegian Ocean Industry Authority (HAVTIL). These audits have been used as case studies and the basis for this paper. Results from the analysis support research findings within the field of human factors and technology development, pointing out that there is a lack of focus on human factors in both development projects and in operations.

    运动中的可穿戴设备已在专业和更高级别的大学中使用,但是在较低的大学级别进行的研究并不多。这项回顾性研究的目的是使用Catapult可穿戴技术收集大数据,开发一种肌肉骨骼建模算法,并纵向确定在12周赛季中III级(DIII)级别的男性大学足球(足球)运动员的工作量。结果表明,在一个季节的过程中,(1)所有职位的平均匹配工作量(432±47.7)比平均训练工作量(252.9±23.3)大1.5倍,(2)前锋位置显示了整个赛季最低的工作量,(3)最高的平均工作量是在第8周(370.1±177.2),而最低的是第4周(219.1±26.4)。这些结果为实现从可穿戴设备收集的数据到数据管理系统的互操作性提供了动力,以优化性能和健康。
    Wearable devices in sports have been used at the professional and higher collegiate levels, but not much research has been conducted at lower collegiate division levels. The objective of this retrospective study was to gather big data using the Catapult wearable technology, develop an algorithm for musculoskeletal modeling, and longitudinally determine the workloads of male college soccer (football) athletes at the Division III (DIII) level over the course of a 12-week season. The results showed that over the course of a season, (1) the average match workload (432 ± 47.7) was 1.5× greater than the average training workload (252.9 ± 23.3) for all positions, (2) the forward position showed the lowest workloads throughout the season, and (3) the highest mean workload was in week 8 (370.1 ± 177.2), while the lowest was in week 4 (219.1 ± 26.4). These results provide the impetus to enable the interoperability of data gathered from wearable devices into data management systems for optimizing performance and health.

    我们调查了体育科学领域中有关体感辅助及其对运动表现的影响的研究的发表偏见的可能性。我们发现有证据表明,期刊倾向于优先考虑具有积极结果的研究(76%),而忽略具有负面结果的研究(2.7%)。令人担忧的是,这可能导致报告的结论与实际研究结果之间存在差异.我们还发现了报告结果与实际绩效变量结果之间的不一致。一起来看,这些数据凸显了未来研究减少偏倚的必要性,并鼓励发表既有正面结果又有负面结果的研究,以提高该领域科学证据的可靠性.
    We investigated the potential for publication bias in the field of sports science regarding studies on ergogenic aids and their effects on exercise performance. We found evidence to suggest that journals tend to prioritize studies with positive results (76%) while neglecting those with negative outcomes (2.7%). Worryingly, this could lead to a discrepancy between reported conclusions and actual study outcomes. We also identified inconsistencies between reported outcomes and actual performance variable outcomes. Taken together, these data highlight the need for future research to reduce bias and encourage the publication of studies with both positive and negative results to improve the reliability of scientific evidence in this field.

    外科医生在精神和身体要求苛刻的工作空间中工作,错误的影响非常重要。术中错误期间准确表征外科医生的神经生理学将有助于指导外科医生和其他远程操作员的更准确的性能评估和精确培训。为了更好地了解术中错误的神经生理学,我们构建并部署了机器人辅助手术(RAS)过程中的术中错误检测和脑电图(EEG)信号同步系统.然后,我们检查EEG数据与检测到的错误之间的关联。我们的结果表明,无论手术经验水平如何,术中错误都可以检测到显着的EEG变化。
    Surgeons operate in mentally and physically demanding workspaces where the impact of error is highly consequential. Accurately characterizing the neurophysiology of surgeons during intraoperative error will help guide more accurate performance assessment and precision training for surgeons and other teleoperators. To better understand the neurophysiology of intraoperative error, we build and deploy a system for intraoperative error detection and electroencephalography (EEG) signal synchronization during robot-assisted surgery (RAS). We then examine the association between EEG data and detected errors. Our results suggest that there are significant EEG changes during intraoperative error that are detectable irrespective of surgical experience level.

    触觉反馈可以增强人类操作员的培训和表现;然而,在机器人辅助任务中用于双向协调的触觉反馈的设计(例如,手术机器人的控制)仍然是一个悬而未决的问题。在这项研究中,我们提出了四个双手动相关的触觉力反馈条件,旨在根据几何特征塑造双手动运动:目标数量,方向,和对称性。触觉条件包括虚拟弹簧,阻尼器,组合弹簧阻尼器,双手之间放置双弹簧。我们评估这些触觉条件对轨迹形状的影响,平滑度,和速度。我们假设,对于没有触觉反馈(1)表现较差的受试者,弹簧将改善平行轨迹的形状,(2)阻尼器将改善点对称轨迹的形状,(3)双弹簧将改善一个目标的轨迹形状,和(4)阻尼器将提高所有轨迹的平滑度。假设(1)和(2)在p<0.001水平上得到了统计学支持,但假设(3)和(4)不支持。此外,双生理依赖的触觉反馈倾向于提高运动的形状准确性,而在没有触觉的情况下,受试者的运动表现较差。因此,基于几何轨迹特征的双向触觉反馈有望提高机器人辅助运动任务的性能。
    Haptic feedback can enhance training and performance of human operators; however, the design of haptic feedback for bimanual coordination in robot-assisted tasks (e.g., control of surgical robots) remains an open problem. In this study, we present four bimanually-dependent haptic force feedback conditions aimed at shaping bimanual movement according to geometric characteristics: the number of targets, direction, and symmetry. Haptic conditions include a virtual spring, damper, combination spring-damper, and dual springs placed between the hands. We evaluate the effects of these haptic conditions on trajectory shape, smoothness, and speed. We hypothesized that for subjects who perform worse with no haptic feedback (1) a spring will improve the shape of parallel trajectories, (2) a damper will improve the shape of point symmetric trajectories, (3) dual springs will improve the shape of trajectories with one target, and (4) a damper will improve smoothness for all trajectories. Hypotheses (1) and (2) were statistically supported at the p < 0.001 level, but hypotheses (3) and (4) were not supported. Moreover, bimanually-dependent haptic feedback tended to improve shape accuracy for movements that subjects performed worse on under no haptic condition. Thus, bimanual haptic feedback based on geometric trajectory characteristics shows promise to improve performance in robot-assisted motor tasks.
