| 1 | On Desideratum for B2C E-Commerce Reputation Systems显示文摘This paper reviews existing approaches to reputation systems,their constraints as well as available solutions. Furthermore,it presents and evaluates a novel and comprehensive reputation model devoted to the distributed reputation system for Business-to-Consumer(B2C) E-commerce applications that overcomes the discussed drawbacks.The algorithm offers a comprehensive approach as it considers a number of issues that have a bearing on trust and reputation such as age of ratings,transaction value,credibility of referees,number of malicious incidents,collusion and unfair ratings.Moreover,it also extends the existing frameworks based on information about past behaviour,with other aspects affecting online trading decisions which relate to the characteristic of the providers,such as existence of trustmark seals,payment intermediaries, privacy statements,security/privacy strategies,purchase protection/insurance,alternative dispute resolutions as well as the existence of first party information. | Anna Gutowska Andrew Sloane Kevan A.Buckley | 2009 | Journal of Computer Science & Technology2009，24，5： | 12 |
| 2 | 用姿势控制能力不足确定脑震荡遗留的神经功能缺损(英文)显示文摘Concussion,or mild traumatic brain injury,incidence rates have reached epidemic levels and impaired postural control is a cardinal symptom.The purpose of this review is to provide an overview of the linear and non-linear assessments of post-concussion postural control.The current acute evaluation for concussion utilizes the subjective balance error scoring system(BESS) to assess postural control.While the sensitivity of the overall test battery is high,the sensitivity of the BESS is unacceptably low and,with repeat administration,is unable to accurately identify recovery.Sophisticated measures of postural control,utilizing traditional linear assessments,have identified impairments in postural control well beyond BESS recovery.Both assessments of quiet stance and gait have identified lingering impairments for at least 1 month post-concussion.Recently,the application of non-linear metrics to concussion recovery have begun to receive limited attention with the most commonly utilized metric being approximate entropy(Ap En).Ap En,most commonly in the medial-lateral plane,has successfully identified impaired postural control in the acute post-concussion timeframe even when linear assessments of instrumented measures are equivalent to healthy pre-injury values;unfortunately these studies have not gone beyond the acute phase of recovery.One study has identified lingering deficits in postural control,utilizing Shannon and Renyi entropy metrics,which persist at least through clinical recovery and return to participation.Finally,limited evidence from two studies suggest that individuals with a previous history of a single concussion,even months or years prior,may display altered Ap En metrics.Overall,non-linear metrics provide a fertile area for future study to further the understanding of postural control impairments acutely post-concussion and address the current challenge of sensitive identification of recovery. | Thomas A.Buckley Jessie R.Oldham Jaclyn B.Caccese | 2016 | Journal of Sport and Health Science2016，5，1： | 3 |

| 4 | Detailed description of Division I ice hockey concussions:Findings from the NCAA and Department of Defense CARE Consortium显示文摘Objective:Since concussion is the most common injury in ice hockey,the objective of the current study was to elucidate risk factors,specific mechanisms,and clinical presentations of concussion in men’s and women’s ice hockey.Methods:Ice hockey players from 5 institutions participating in the Concussion Assessment,Research,and Education Consortium were eligible for the current study.Participants who sustained a concussion outside of this sport were excluded.There were 332(250 males,82 females)athletes who participated in ice hockey,and 47(36 males,11 females)who sustained a concussion.Results:Previous concussion(odds ratio(OR)=2.00;95%confidence interval(95%CI):1.02‒3.91)was associated with increased incident concussion odds,while wearing a mouthguard was protective against incident concussion(OR=0.43;95%CI:0.22‒0.85).Overall,concussion mechanisms did not significantly differ between sexes.There were specific differences in how concussions presented clinically across male and female ice hockey players,however.Females(9.09%)were less likely than males(41.67%)to have a delayed symptom onset(p=0.045).Additionally,females took significantly longer to reach asymptomatic(p=0.015)and return-to-play clearance(p=0.005).Within the first 2 weeks post-concussion,86.11%of males reached asymptomatic,while only 45.50%of females reached the same phase of recovery.Most males(91.67%)were cleared for return to play within 3 weeks of their concussion,compared to less than half(45.50%)of females.Conclusion:The current study proposes possible risk factors,mechanisms,and clinical profiles to be validated in future concussions studies with larger female sample sizes.Understanding specific risk factors,concussion mechanisms,and clinical profiles of concussion in collegiate ice hockey may generate ideas for future concussion prevention or intervention studies. | Kathryn L.Van Pelt Jaclyn B.Caccese James T.Eckner Margot Putukian MAlison Brooks Kenneth L.Cameron Megan N.Houston Matthew A.Posner Jonathan C.Jackson Gerald T.McGinty Cameron J.Hillis Thomas W.McAllister Michael A.McCrea Steven P.Broglio Thomas A.Buckley | 2021 | Journal of Sport and Health Science2021，10，2： | 1 |
| 5 | Concussion research: Moving beyond the natural history显示文摘The topic of sports-related concussion has been,and will likely continue to be,one of the most challenging topics in sports medicine.The last 2 decades of research has fundamentally altered clinician’s and the public’s view of concussions from a relatively minor“ding”to be shaken off with rapid return to play to the current realization that concussions are brain injuries with potential lifelong consequences.The National Collegiate Athletic Association(NCAA)and the Department of Defense(DoD)Concussion Assessment,Research and Education(CARE)Consortium Study1 currently elucidating the natural history of concussion will provide clinicians critical recommendations on the diagnosis and management;however,many neuropsychosocial questions remain unanswered.Thus,this special topic on Emerging Concussion Research of the Journal of Sport and Health Science(JSHS)is dedicated to addressing key concussion related questions that extend beyond typical clinical concussion management to include broad public health-related concerns. | Thomas A.Buckley | 2021 | Journal of Sport and Health Science2021，10，2： | 0 |
| 6 | 英格兰职业足球运动员的脑震荡知识与态度(英文)显示文摘背景:脑震荡是足球运动中一种普遍的病理类型,但球员和管理人员对其还存在大量误解。为消除这些误解并减少脑震荡相关的潜在后遗症,开展有效的教育干预措施十分必要。进行适当干预措施,需调查球员对脑震荡知识的了解现状及其态度。本研究旨在评估英格兰职业足球运动员对脑震荡知识的了解及态度。方法:本研究调查对象为一家英冠联赛俱乐部的26名球员,采用罗森鲍姆脑震荡知识和态度调查问卷(RoCKAS)和半结构式访谈相结合的调查方式。RoCKAS包括独立的知识分(0-25)和态度分(15-75),半结构式访谈包括脑震荡知识、态度和行为相关问题。结果:RoCKAS中平均知识分与态度分分别为16.4±2.9(11-22)和59.6±8.5(41-71)。随后的访谈印证了球员RoCKAS分数与其行为意图确实不一致,证实他们对脑震荡存在各种误解,并指出脑震荡报告的现有障碍。结论:本研究结果显示英冠联赛球员在回答纸质问卷时有中度的脑震荡知识水平和安全态度,以及良好的脑震荡症状识别能力;但在半结构式访谈中,许多受访者尽管意识到潜在风险,对脑震荡仍有不安全行为表现。另外,本研究还确定了多种脑震荡报告的相关障碍,包括对损伤的感知严重性、比赛状况、球员替换规则等。这些结果能帮助形成教育干预基础,从而有望在职业足球运动员中改善脑震荡报告行为。 | Joshua M.Williams Jody L.Langdon James L.Mc Millan Thomas A.Buckley | 2016 | Journal of Sport and Health Science2016，5，2： | 0 |
| 7 | Effects of contact/collision sport history on gait in early-to mid-adulthood显示文摘Background:To determine the effect of contact/collision sport participation on measures of single-task(ST)and dual-task(DT)gait among early-to middle-aged adults.Methods:The study recruited 113 adults(34.88±11.80 years,(mean±SD);53.0%female)representing 4 groups.Groups included(a)former non-contact/collision athletes and non-athletes who are not physically active(n=28);(b)former non-contact/collision athletes who are physically active(n=29);(c)former contact/collision sport athletes who participated in high-risk sports and are physically active(n=29);and(d)former rugby players with prolonged repetitive head impact exposure history who are physically active(n=27).Gait parameters were collected using inertial measurement units during ST and DT gait.DT cost was calculated for all gait parameters(double support,gait speed,and stride length).Groups were compared first using one-way analysis of covariance.Then a multiple regression was performed for participants in the highrisk sport athletes and repetitive head impact exposure athletes groups only to predict gait outcomes from contact/collision sport career duration.Results:There were no significant differences between groups on any ST,DT,or DT cost outcomes(p>0.05).Contact/collision sport duration did not predict any ST,DT,or DT cost gait outcomes.Conclusion:Years and history of contact/collision sport participation does not appear to negatively affect or predict neurobehavioral function in early-to mid-adulthood among physically active individuals. | Katherine J.Hunzinger Jaclyn B.Caccese Rebekah Mannix William P.MeehanⅢ Jocelyn F.Hafer C.Buz Swanik Thomas A.Buckley | 2023 | Journal of Sport and Health Science2023，12，3： | 0 |
| 8 | 脑震荡史运动员采用保守步态策略的证据(英文)显示文摘背景:3次或3次以上的脑震荡史常与许多短期或长期神经病理相关。姿势控制障碍是目前已知的脑震荡导致的严重后果之一,而关于多重脑震荡对步态影响的研究较少。本研究旨在评价有脑震荡史的大学生运动员的步态特征。方法:将63名受试者根据脑震荡史分为3组:≥3次脑震荡史、1-2次脑震荡史、无脑震荡史。每个受试者在4.9 m的检测步道上完成10次步态实验。因变量包括步态特征(步速、步长、步宽、双脚支撑时间、步态周期百分比)及变异系数(步长、时间、步宽)。先用多元方差分析比较步态特征,进而跟进用单因素方差分析,并根据情况用图基事后检验法。用单因素方差分析和图基事后检验法比较变异系数。结果:分组的主要影响包括步速、步长、步宽、双脚支撑时间。总体而言,无脑震荡史组表现出健康年轻人典型的步态参数,并明显优于其他两组。其步长变异系数更佳,但步行时间或步宽的变异系数与其他组无显著差异。结论:这一发现为有脑震荡史的个体在步态测试时表现出细微姿势控制障碍提供了证据,可作为以后研究神经缺陷的早期指标。变异性测量的差异有限,这与前期静态姿势的研究结果一致,表明个体会限制其运动系统以减少变异性。总之,本研究证明有脑震荡史的个体应采取保守的步态策略。 | Thomas A.Buckley Srikant Vallabhajosula Jessie R.Oldham Barry A.Munkasy Kelsey M.Evans David A.Krazeise Caroline J.Ketcham Eric E.Hall | 2016 | Journal of Sport and Health Science2016，5，4： | 0 |
