| 1 | 基于社会认知理论的消费者采用模型与实证研究显示文摘根据Bandura的社会认知论,消费者、新技术和采用三者之间是一个辩证的三方互惠决定体系。通过对几种基本的用户接受度模型(TAM、TPB、VAM)进行综述和分析,本文采用三方互惠决定论的理论框架,结合价值理论和自我效能感的概念提出一个新的用户接受度模型——基于自我效能感的价值接受度模型(SVAM)。针对新兴的移动互联网业务,本文采用结构方程模型(SEM)对移动拍卖的用户接受进行了实证研究。结果表明,基于自我效能感的价值接受度模型SVAM可以更好地解释用户的采用意图。在自愿购买的消费市场中,用户的自我效能感影响了用户对产品或服务的感知价值,并直接影响消费者的态度和采用意图。尤其当消费者缺乏基本的使用经验时,自我效能感将具有更显著的影响作用。 | 朱阁 马龙 Sangwan Sunanda 吕廷杰 | 2010 | 南开管理评论2010,13,3: | 45 |
| 2 | 基于多Agent的在线多属性采购拍卖的机制设计显示文摘对目前网络拍卖进行研究发现,在线多属性采购拍卖的实施水平仍处在基础的信息发布阶段。基于委托代理模型的参与约束和激励相容约束,通过改进多属性决策的一般方法,提出一种以释放权重信息为核心的在线多属性采购拍卖设计机制。拍卖设计的第一阶段融入谈判机制以协商拍卖的属性规则,确定多维拍卖的属性选择;第二阶段通过投标人提供的属性赋值和权重设置确定赢者的胜出。为开发实际的在线网络采购或供应链管理平台,进一步提出基于多Agent系统的多属性采购拍卖的技术实现框架。通过一个简单的二维属性拍卖的例证分析,说明该机制可以增进拍卖双方信息的正向交互,实现拍卖机制的最优,并可以通过多Agent系统提高在线拍卖的效率。 | 朱阁 吕廷杰 付瑞雪 Sunanda Sangwan | 2009 | 管理科学2009,22,1: | 15 |
| 3 | 培养角膜缘上皮移植后穿透性角膜移植术的早期结果显示文摘目的:描述曾行培养角膜缘上皮移植的患者再行穿透性角膜移植(PKP)的早期结果。
方法:对因化学烧伤造成角膜缘干细胞缺乏而行培养的角膜缘上皮移植后又进行穿透性角膜移植术的患者有关人口统计学、原发病因、角膜缘移植类型、眼表稳定性、视力、移植片透明度和并发症方面的资料进行回顾和复习。对受体角膜片组织病理学特征进行研究,重点观察上皮状态。
结果:在患有角膜缘干细胞缺乏而进行培养的角膜缘上皮移植术的125例患者中,15例接受了穿透性角膜移植术(PKP)。角膜缘上皮移植术后(自体移植组n=11,同种异体移植组n=4)平均间隔时间为7个月(范围2—12个月)。同种异体移植组的4例患者均接受了免疫抑制疗法。15只眼中14只眼(93%)获得了含有稳定的角膜上皮的健全的角膜植片。15只眼中14只眼术前最佳矫正视力低于20/200。PKP后平均随访8.3±5.0个月,8只眼最佳矫正视力高于20/60,5只眼最佳矫正视力20/200至20/60。2只眼低于20/200。15只眼中3只眼发生异体角膜植片的排斥反应但被成功治疗。1只眼发生植片排斥的同时发生了青光眼。同种异体角膜缘上皮移植无一例显示排斥表现。
结论:培养的角膜缘上皮移植后,在形成稳定的眼表后行PKP的早期结果是良好的。为了避免排斥反应,培养的同种异体角膜缘上皮移植者行充分的免疫抑制治疗是必需的。角膜同种异体移植能够单独排斥同种异体角膜缘移植物。 | Virender S. Sangwan Himanshu P. Matalia Geeta K. Vemuganti Ghazala Ifihekar Anees Fatima Shashi Singh, Gullapalli N. Rao 董白霞(译) 马景学(校) | 2005 | 美国医学会眼科杂志(中文版)2005,17,4: | 5 |
| 4 | 中阿尔金南缘志留纪高压泥质片麻岩的发现及其构造地质意义显示文摘在中阿尔金南缘西段尤努斯萨依北部原划长城系巴什库尔干岩群中首次发现一套高压泥质片麻岩。根据岩相学观察和矿物化学成分可识别出其四期矿物共生组合:早期为石榴子石+多硅白云母+单斜辉石(?)+斜长石+黑云母+石英+金红石+钛铁矿;第二期为石榴子石+蓝晶石+钾长石+斜长石+黑云母+石英+金红石+钛铁矿;第三期为石榴子石+夕线石+钾长石+斜长石+黑云母+石英+金红石+钛铁矿;晚期为石榴子石+夕线石+斜长石+黑云母+石英+钛铁矿。依据矿物内部一致性热力学数据,基于THERMOCALC 3. 40程序平台,计算出P-T视剖面图,并结合矿物等值线、矿物对温压计等计算,依次确定四期变质温压条件为15. 8~18. 3kbar/646~729℃、10. 30~12. 30kbar/781~821℃、8. 50~9. 60kbar/812~838℃和4. 65~5. 70kbar/698~725℃。上述四期变质阶段共同构成一个早期降压升温后降压降温的顺时针型演化的P-T轨迹,指示出与陆壳俯冲-折返相关的变质地质事件。利用LA-ICP-MS进行的锆石原位微区U-Pb定年和微量元素分析结果表明,该岩石记录了432. 0±2. 7Ma、401. 4±2. 5Ma和381. 1±2. 4Ma三期变质年龄,可能分别代表了该岩石早期高压、中期高压麻粒岩相-麻粒岩相和后期角闪岩相变质阶段的时代。该高压岩石出露于中阿尔金地块西段南缘长城系巴什库尔干岩群之中,与南侧以断裂带分隔的赋存于阿尔金岩群之中的南阿尔金高压-超高压岩石出露的构造位置明显不同,其峰期变质时代(~432Ma)亦明显不同于南阿尔金高压-超高压岩石的峰期变质时代(~500Ma)。因此,该高压岩石与南阿尔金高压-超高压岩石显然不能构成同一条变质岩带。结合区域地质背景和前人关于柴北缘陆壳属性高压-超高压岩石峰期变质时代(~430Ma)的研究成果综合分析,本文初步认为该高压岩石可能是柴北缘高压-超高压变质岩带的西延或是被中新生代以来阿尔金复杂多期次走滑断裂系迁移而就位于中阿尔金南缘的部分柴北缘高压-超高压变质岩片/岩块。 | 马拓 刘良 盖永升 杨文强 王超 康磊 廖小莹 PAK SangWan | 2019 | 岩石学报2019,35,6: | 4 |

| 6 | Correlation between soluble receptor for advanced glycation end products levels and coronary artery disease in postmenopausal nondiabetic women显示文摘BACKGROUND The established cardiovascular risk factors cannot explain the overall risk of coronary artery disease(CAD),especially in women.Therefore,there is a growing need for the assessment of novel biomarkers to identify women at risk.The receptor for advanced glycation end products(RAGE)and its interaction with the advanced glycation end product(AGE)ligand have been associated with atherogenesis.The soluble fraction of RAGE(sRAGE)antagonizes RAGE signaling and exerts an antiatherogenic effect.AIM The study aim was to explore the association between plasma levels of sRAGE and CAD in nondiabetic postmenopausal women.METHODS This case-control study included 110 nondiabetic postmenopausal women who were enrolled in two groups.Group I included 55 angiographically proven CAD subjects with>50%stenosis in at least one of the major coronary arteries and Group II included 55 healthy control women who did not have CAD or had<50%stenosis of the coronary arteries.Stenosis was confirmed by invasive angiography.Plasma sRAGE was determined by an enzyme-linked immunosorbent assay.RESULTS We observed significantly lower plasma sRAGE concentrations in subjects with CAD vs healthy controls(P<0.05).Univariate and multivariate logistic regression analysis also revealed a significant correlation between plasma sRAGE levels and CAD(P=0.01).Multivariate odds ratios for CAD revealed that subjects with sRAGE concentrations below 225 pg/mL(lowest quartile)had a 6-fold increase in CAD prevalence independent of other risk factors.CONCLUSION Our findings indicated that low sRAGE levels were independently associated with CAD in nondiabetic postmenopausal women.Risk assessment of CAD in postmenopausal women can be improved by including sRAGE along with other risk factors. | Soumitra Ghosh Divya Kapoor Rajesh Vijayvergiya Sonal Sangwan Sujata Wangkheimayum Sakshi Mehta Veena Dhawan | 2021 | World Journal of Cardiology2021,13,5: | 2 |

| 13 | A Review and Analysis of Localization Techniques in Underwater Wireless Sensor Networks显示文摘In recent years,there has been a rapid growth in Underwater Wireless Sensor Networks(UWSNs).The focus of research in this area is now on solving the problems associated with large-scale UWSN.One of the major issues in such a network is the localization of underwater nodes.Localization is required for tracking objects and detecting the target.It is also considered tagging of data where sensed contents are not found of any use without localization.This is useless for application until the position of sensed content is confirmed.This article’s major goal is to review and analyze underwater node localization to solve the localization issues in UWSN.The present paper describes various existing localization schemes and broadly categorizes these schemes as Centralized and Distributed localization schemes underwater.Also,a detailed subdivision of these localization schemes is given.Further,these localization schemes are compared from different perspectives.The detailed analysis of these schemes in terms of certain performance metrics has been discussed in this paper.At the end,the paper addresses several future directions for potential research in improving localization problems of UWSN. | Seema Rani Anju Anupma Sangwan Krishna Kumar Kashif Nisar Tariq Rahim Soomro Ag.Asri Ag.Ibrahim Manoj Gupta Laxmi Chandand Sadiq Ali Khan | 2023 | Computers, Materials & Continua2023,,6: | 1 |
