| 1 | Healthcare data analytics:using a metadata annotation approach for integrating electronic hospital records显示文摘The data in electronic medical records(EMR)are complex in structure.They are independent,yet related to each other.In order to improve information access through the use of EMR,annotating work on these data is necessary.The annotation on metadata,the resource data which contain a meta-model of the database,is the basis of the annotating work if a semi-automated or an automated annotating approach which aims at making the database more accessible is expected.In this study,a method has been proposed to transform the terms which cannot be matched directly by changing them literally but maintaining their semantics,and then annotating them indirectly.After the transforming work,a refinement method which is reducible to phrase sense disambiguation(PSD)is employed to ensure accuracy.A pilot study on a hospital database has been conducted to test the accuracy and effectiveness of the proposed method. | Boyi Xu Ke Xu LiuLiu Fu Ling Li Weiwei Xin Hongming Cai | 2016 | Journal of Management Analytics2016，3，2： | 6 |
| 2 | The impact of XBRL on information asymmetry:evidence from loan contracting显示文摘This paper examines whether and how the adoption of eXtensible Business Reporting Language(XBRL)reduces information asymmetry in loan contracting.We hypothesize that the adoption of XBRL can enhance information dissemination and mitigate the information asymmetry problem between borrowers and lenders.Using a sample of 554 US bank loan contracts,we find that borrowers who adopt XBRL enjoy more favourable price and nonprice terms of bank loan contracts.Additional analyses indicate that the relations among XBRL adoption and bank loan price vary with loan structure.Overall,this research provides evidence that technology advancements such as XBRL reduce cost of bank loans by decreasing information asymmetry between borrowers and lenders. | Dazhi Chong Hui Shi Liuliu(Luna)Fu Hao Ji Gongjun Yan | 2017 | Journal of Management Analytics2017，4，2： | 1 |
| 3 | An evolving trajectory-from PD,logistics,SCM to the theory of material flow显示文摘The growing interest in the material flow(MF)theory has invoked much interesting research in recent years.Although the MF theory is relatively new,a review of the related literature from a historical perspective shows that MF theory represents a new stage of the evolutionary development of interrelated subjects such as Physical Distribution(PD),Logistics,and Supply Chain Management(SCM).The purpose of this paper is to provide a summative review of the evolution of the subjects of PD,Logistics,and SCM,and their new development,MF theory.The paper aims at tracing how concepts and findings in PD,Logistics,SCM,and MF have been developed and have evolved.The study shows that PD evolved to Logistics in middle of the 1980s;starting from the late 1990s,Logistics has evolved to SCM;and today PD,Logistics,and SCM can be considered to be under the umbrella provided by a new theory called MF theory.This paper points out that MF theory is a necessity to deal with the overwhelming complexity of material flow systems in the global economy of the twenty-first century. | Hanping Hou Mikhail Yu Kataev Zuopeng(Justin)Zhang Sohail Chaudhry Huiqi Zhu Liuliu Fu Mingli Yu | 2015 | Journal of Management Analytics2015，2，2： | 0 |
| 4 | Impact of hospital size on healthcare information system effectiveness: evidence from healthcare data analytics显示文摘With the rapid development of information technology, the increasing use ofmobile digital devices and efforts from the whole society, the healthcareinformation systems (HISs) are moving towards a new era. However, there isstill a lack of clear understanding of the benefits of HIS at the hospital leveland the influential factors for HIS effectiveness. In this study, we propose aresearch framework to explain how HIS implementation improves hospitalperformance. Our results reinforce the positive effect of HIS on hospitalperformance. In particular, we found that HIS implementation increases boththe cost and revenue of the hospitals, but the increasing effect in revenue ismuch bigger than the increasing effect in cost. We also found that althoughboth small and big hospitals benefit from the implementation of HIS, the effectof size is different. Size has a positive effect on hospital performance for smallhospitals but has a negative effect on big hospitals. This indicates that thecompetitive advantage of economies of scale disappears for big hospitalsbecause the level of information transparency becomes lower and transactioncosts become higher as size increases. | Liuliu Fu Ling Li Lusi Li Wenlu Zhang Zihao Luo | 2022 | Journal of Management Analytics2022，9，2： | 0 |
