1体育运动领域流畅状态的研究进展显示文摘流畅状态是一种理想的内部体验状态,在体育运动领域也被称之为个体从事活动的最佳体验。由于其可以为个体提供良好的心境状态,有助于促进个体对活动的内部动机,提高个体的活动效率,所以,流畅状态作为一个重要的研究领域在运动心理学的发展过程中发挥着重要的作用。拟对体育运动情境中流畅状态的心理特征、模型构建及研究方法进行详细的阐述;并对相关的研究成果加以评述,如流畅状态的跨文化普遍性,体育运动中流畅体验的倾向性差异,流畅-运动技能表现间的关系,影响流畅状态的因素及其相应的调控措施。在此基础上提出,本领域的未来发展应拓展对流畅状态心理特征的研究,即以那些处于非西方文化和西方文化中少数民族文化背景下的群体作为研究对象,进行不同背景的跨文化对比研究;同时,对流畅模型的进一步改进,以充实流畅状态的理论架构,也应成为未来研究的一个焦点;此外,通过目标设置等心理干预手段以促进运动员流畅状态的发生,以及为流畅状态与运动技能建立明确的中介模型,从而应用于运动技能提升的实践情境中也将是未来研究的新主题。刘微娜 季浏 Watson ⅡJack C 2009体育科学2009,29,11:34
2PM_(2.5)及其测量与影响研究简史显示文摘美国率先建立的国家环境空气质量标准(NAAQS)旨在保护公众健康,而该理念已被包括中国在内的众多国家所采用。针对大气悬浮颗粒物(PM),NAAQS根据PM在仪器检测以及人体吸入时的粒径选择性特征,定义了总悬浮颗粒(TSP)、PM_(10)、PM_(2.5)及其相应的质量浓度标准。这些指标的建立是基于长达300年来颗粒物监测技术发展及其危害评价的结果。因此2012年中国在颁布实施新PM_(2.5)空气质量标准时,PM_(2.5)的监测及评价方面有了更多科学积累与技术选择。本文简要回顾了PM的粒径分布、化学组成、可吸入特征、人体健康效应及空气质量标准等研究简史,根据其他国家的发展经验,提出中国在观测网络设计、测量仪器选择和使用、质量控制和质量保证及监测结果分析等方面需要确立自己独特的行业指南。对于未来空气质量的管理和标准制定,应同时考虑多种污染物及其对公众健康、能见度、气候、材料及生态系统的影响。CHOW Judith C 曹军骥 李顺诚 王小亮 WATSON John G 2012地球环境学报2012,3,5:17
3miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium.Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey 2011World Journal of Gastroenterology2011,17,8:13
4流畅状态的认知干预:目标设置显示文摘目标设置与流畅状态间存在着中高级的相关,这一关系很可能是源于目标设置的认知功能。以2min5点定点投篮(篮球)作为活动任务,以修订的中文版《特质流畅量表-2》和《状态流畅量表-2》作为测量工具,采用2(目标定向:自我/任务定向)×3(目标难度:容易/中等难度/困难)实验设计,探讨目标定向和目标难度对流畅状态的影响。结果表明:实验后,实验组受试的特质流畅和状态流畅得分显著高于控制组受试:目标定向对特质流畅和状态流畅的主效应均达显著水平,任务定向高于自我定向;目标难度对特质流畅和状态流畅的主效应均达到显著水平,中等难度目标优于容易目标和困难目标。刘微娜 季浏 Watson Ⅱ Jack C 2013上海体育学院学报2013,37,2:7

6健康领域的文化能力显示文摘1背景 尽管人类对其他社会的兴趣纵贯历史的各个阶段,但是检验不同文化概念对人类健康实践的影响从20世纪才开始,当时是伴随着长期的人类学田野调查产生的,这些田野调查揭露了不同文化之间相关卫生实践的多样性、复杂性和连续性。Napier A D Ancarno C Butler B Calabrese j Chater A Chatterjee H Guesnet F Home R Jacyna S Jadhav S Macdonald A Neuendorf U Parkhurst A Reynolds R Scambler G Shamdasani S Smith S Z Stougaard-Nielsen J Thomson L Tyler N Volkmann A M Walker T Watson J Williams AC Willott C Wilson J Woolf K 2016中国卫生政策研究2016,9,2:5
7MicroRNA profile in neosquamous esophageal mucosa following ablation of Barrett's esophagus显示文摘AIM To investigate the micro RNA expression profile in esophageal neosquamous epithelium from patients who had undergone ablation of Barrett's esophagus.METHODS High throughput screening using Taq Man~ Array Human Micro RNA quantitative PCR was used to determine expression levels of 754 micro RNAs in distal esophageal mucosa(1 cm above the gastro-esophageal junction) from 16 patients who had undergone ablation of non-dysplastic Barrett's esophagus using argon plasma coagulation vs pretreatment mucosa, posttreatment proximal normal non-treated esophageal mucosa, and esophageal mucosal biopsies from 10 controls without Barrett's esophagus. Biopsies of squamous mucosa were also taken from 5 cm above the pre-ablation squamo-columnar junction. Predicted m RNA target pathway analysis was used to investigate the functional involvement of differentially expressed micro RNAs.RESULTS Forty-four micro RNAs were differentially expressed between control squamous mucosa vs post-ablation neosquamous mucosa. Nineteen micro RNAs were differentially expressed between post-ablation neosquamous and post-ablation squamous mucosa obtained from the more proximal non-treated esophageal segment. Twelve microRNAs were differentially expressed in both neosquamous vs matched proximal squamous mucosa and neosquamous vs squamous mucosa from healthy patients. Nine micro RNAs(mi R-424-5p, mi R-127-3p, mi R-98-5p, mi R-187-3p, mi R-495-3p, mi R-34c-5p, mi R-223-5p, mi R-539-5p, mi R-376a-3p, mi R-409-3p) were expressed at higher levels in post-ablation neosquamous mucosa than in matched proximal squamous and healthy squamous mucosa. These micro RNAs were also more highly expressed in Barrett's esophagus mucosa than matched proximal squamous and squamous mucosa from controls. Target prediction and pathway analysis suggests that these micro RNAs may be involved in the regulation of cell survival signalling pathways. Three micro RNAs(mi R-187-3p, mi R-135b-5p and mi R-31-5p) were expressed at higher levels in postablation neosquamous mucosa than in matched proximal squamous and healthy squamous mucosa. These mi RNAs were expressed at similar levels in preablation Barrett's esophagus mucosa, matched proximal squamous and squamous mucosa from controls. Target prediction and pathway analysis suggests that these micro RNAs may be involved in regulating the expression of proteins that contribute to barrier function.CONCLUSION Neosquamous mucosa arising after ablation of Barrett's esophagus expresses micro RNAs that may contribute to decreased barrier function and micro RNAs that may be involved in the regulation of survival signaling pathways.Loveena Sreedharan George C Mayne David I Watson Timothy Bright Reginald V Lord Alfiya Ansar Tingting Wang Jakob Kist David StJ Astill Damian J Hussey 2017World Journal of Gastroenterology2017,23,30:3

10文化、不平等性与卫生服务提供显示文摘1动态不平等性对基层医疗卫生人力的影响 政治、社会、文化、专业群体皆建立在一致且常规的人类行为之上。当遭受巨大变革和内外压力时,这些群体会变得十分脆弱。尤其在动荡时期,这些群体往往更关注社会和文化的差异性,而非二者的一致性。尽管社会中的个体思维和行为会呈现较大的差异,但对健康的感知具有统一性,并在更广范围人群内尤为突出,这主要归因于文化价值观的作用。广义的文化心态会随着时间和地理位置的不同而不同,就像健康的社会决定因素也会因文化类型的不同而产生差异。Napier A D Ancarno C Butler B Calabrese J Chater A Chatterjee H Guesnet F Horne R Jacyna S Jadhav S Macdonald A Neuendorf U Parkhurst A Reynolds R Scambler G Shamdasani S Smith S Z Stougaard-Nielsen J Thomson L Tyler N Volkmann A M Walker T Watson J Williams A C Willott C Wilson J Woolf K 2016中国卫生政策研究2016,9,3:2
11兵马俑博物馆冬季室内大气悬浮颗粒物与游客数量的关系显示文摘通过对秦始皇兵马俑博物馆铜车马展厅和一号坑室内采集的冬季大气悬浮颗粒物进行单颗粒分析,评价了在具有不同通风条件的两个展厅中,游客数量对大气悬浮颗粒物的影响。研究中采用配备能谱的扫描电子显微镜对单颗粒进行了形貌和元素组成分析,以判断室内悬浮颗粒的来源和化学组成差异,同时监测了两个展厅室内的微环境变化。结果显示,在铜车马展厅室内悬浮颗粒的昼夜质量浓度之比(1.30-3.12),明显高于同期的一号坑(0.96-2.59)和室外(0.68-1.79),表明在铜车马展厅游客数量对颗粒物质量浓度的贡献大于在一号坑内。室内、外对比的结果表明,悬浮颗粒物的质量浓度、粒径分布和颗粒类型等特性,在配备了机械通风设备的铜车马展厅中受游客数量的影响较大,而在自然通风为主的一号坑中,通风条件则成为决定因素。颗粒物组成分析显示,博物馆冬季的室内悬浮颗粒主要由黄土中的矿物颗粒、烟炱等低原子序数的颗粒、硫酸盐、燃煤飞灰和生物质颗粒组成。除烟炱和铝硅酸盐会造成对文物的脏污外,随着温、湿度的波动,硫酸钙的结晶、溶解、渗透和再结晶作用都会产生应力,导致兵马俑表面的风化。胡塔峰 曹军骥 李旭祥 Lee Shun-Cheng Judith C Chow John G Watson 容波 2009中国粉体技术2009,15,2:2
