基于数据特征的大型仪器共享服务绩效评价模型     

吴斌  刘薇  邬平  李俊  诸开梅 《科技管理研究》2020,(14)

仪器拥有单位对大型科学仪器的管理水平存在差异,采用固定权值评价指标考量共享服务绩效存在不合理性。通过对云南省大型科研仪器开放共享管理平台的绩效考核指标进行分析,根据仪器管理单位的内置属性将指标进行关联耦合,产生以仪器平均原值为考量基线,对外服务营运共享收益与对外服务单位数为考量的评价维度。基于共享服务记录数据特征,利用评价维度建立不同内置属性仪器管理单位的SSP评价模型。通过真实数据验证,SSP评价模型考量的结果与真实结果误差率为26.67%,基于数据特征的共享绩效评价模型具有一定的准确度。模型计算结果能客观反映仪器管理单位的共享服务能力和水平,为政府管理部门公平、公证地实施奖励性后补助工作提供评价依据和参考。  相似文献   

An empirical study of the antecedents of data completeness in electronic medical records     

《International Journal of Information Management》2020

There is a body of research that highlights the role of data management to improve the quality of data, which in return improves organizational performance. The literature in data management has indicated the five theoretical constructs used to understand the factors influencing data quality, including top management support, capability on the regulation and process management, business-IT alignment, staff participation, and integration of information systems. However, it is unclear how these theoretical constructs can be utilized to understand the antecedents of data completeness as a dimension of data quality. Following that stream of research, the current paper examines the factors influencing data completeness in electronic medical records (EMR). The scope of this study is by only surveying medical professionals at healthcare settings in northern Nevada. The empirical results reveal that resources should be added as one of the antecedents of data completeness in EMR.  相似文献   

Cloud-based big data analytics for customer insight-driven design innovation in SMEs     

《International Journal of Information Management》2020

Fast development of IT and ICT facilitate customers to post a large volume of their concerns and expectation online, which are widely accepted to be a valuable resource for product designers. However, it is found that only a small number of small and medium-sized enterprises (SMEs) have capabilities to leverage customer online insights for design innovation, which often demonstrate a significant share in national economies growth. To discover the beneath reasons regarding the barrier that prevent them to make effective utilization, in this study, as a concrete example, manufacturing SMEs in the South Wales and Greater Manchester industrial areas of the UK are focused and their potential motivations for using and knowledge of big data-based customer analytics are investigated. An exploratory survey was conducted in terms of the type of customer data they have, the storage approaches, the volume of customer data, etc. Next, a carefully devised exploratory study was undertaken to understand how SMEs perceive the relations between customer data and product design, how about their expectations from big customer data analytics and what really challenges SMEs to exploit the value of big customer data. Besides, a demonstration platform is developed to present SMEs an automatic process of analysing customer online reviews and the capacity on customer insights acquisition and strategic decision making. Finally, findings from two focus groups indicate the different managerial and technical considerations required for SMEs considering implementing big data and customer analytics. This study encourages SMEs to welcome big customer data and suggests that a cloud-based approach may be the most appropriate way of giving access to big data analytics techniques.  相似文献
