企业高层管理者之信息需求--软信息

对高层管理者信息需求的研究 ,是高层管理信息系统 (EIS)功能设计与成功应用的基础。本文以高层管理者在用人、沟通、决策三个层面的工作为主线 ,探讨了高层管理者的信息需求 ,并指出了高层管理者所要求的信息具有非规范性、随机性、模糊性和主观性的特征。为与传统的MIS所产生的定期的、规范化的数据报表相区别 ,本文将具有这些特点的信息称之为软信息。进而指出EIS在高层管理中成功应用的关键是EIS必须具备软信息的服务功能

What is the future of electrical impedance spectroscopy in flow cytometry?

More than 20 years ago, electrical impedance spectroscopy (EIS) was proposed as a potential characterization method for flow cytometry. As the setup is comparably simple and the method is label-free, EIS has attracted considerable interest from the research community as a potential alternative to standard optical methods, such as fluorescence-activated cell sorting (FACS). However, until today, FACS remains by and large the laboratory standard with highly developed capabilities and broad use in research and clinical settings. Nevertheless, can EIS still provide a complement or alternative to FACS in specific applications? In this Perspective, we will give an overview of the current state of the art of EIS in terms of technologies and capabilities. We will then describe recent advances in EIS-based flow cytometry, compare the performance to that of FACS methods, and discuss potential prospects of EIS in flow cytometry.     

政府应急情报系统服务能力影响因素研究

[目的/意义]我国政府应急情报系统普遍存在重建设轻应用,高投入低效能等问题,系统服务能力难以达到用户期望的水平,对应急管理工作的支撑作用仍不理想。而当前学界与业界对如何提升应急情报系统服务能力的探讨也较少。[方法/过程]梳理了安全情报、应急情报、IT能力管理、IS服务质量评价等领域文献,将应急情报系统服务能力的影响因素归纳为用户因素、技术因素和环境因素三个方面,构建了影响因素模型,并运用问卷调查、专家访谈及结构方程模型对研究假设进行了实证检验。[结果/结论]结果表明用户因素对服务能力存在直接正向影响,而技术因素和环境因素则通过用户因素的完全中介作用间接产生正向影响。研究进一步分析了影响因素间的路径关系与影响机理,为应急各部门提升应急情报系统服务能力提供了理论参考与建议。     

高层领导风格在企业系统生命周期各个阶段的权变性研究

企业信息系统生命周期的各个阶段面临着不同的关键任务,需要高层管理者表现出不同的领导风格,通过领导风格和企业信息系统生命周期各个阶段的匹配,以有效地促进企业信息系统在各个阶段的成功。通过对威海一家具有较长信息化经历的企业进行案例研究发现,在系统采纳阶段,变革型的领导风格更有助于企业关注于未来的发展并及时做出战略性决策;在系统实施阶段,交易型的领导风格更有助于管理和控制具体的实施任务;在消化吸收和扩展阶段,变革和交易混合型的领导风格更有利于系统和企业内部业务流程的融合,以及系统向外部供应链的扩展。本文的研究成果能够为企业在信息系统生命周期的不同阶段选择合适的信息化领导人提供指导。     

Electronic information sharing in local government authorities: Factors influencing the decision-making process

Local Government Authorities (LGAs) are mainly characterised as information-intensive organisations. To satisfy their information requirements, effective information sharing within and among LGAs is necessary. Nevertheless, the dilemma of Inter-Organisational Information Sharing (IOIS) has been regarded as an inevitable issue for the public sector. Despite a decade of active research and practice, the field lacks a comprehensive framework to examine the factors influencing Electronic Information Sharing (EIS) among LGAs. The research presented in this paper contributes towards resolving this problem by developing a conceptual framework of factors influencing EIS in Government-to-Government (G2G) collaboration. By presenting this model, we attempt to clarify that EIS in LGAs is affected by a combination of environmental, organisational, business process, and technological factors and that it should not be scrutinised merely from a technical perspective. To validate the conceptual rationale, multiple case study based research strategy was selected. From an analysis of the empirical data from two case organisations, this paper exemplifies the importance (i.e. prioritisation) of these factors in influencing EIS by utilising the Analytical Hierarchy Process (AHP) technique. The intent herein is to offer LGA decision-makers with a systematic decision-making process in realising the importance (i.e. from most important to least important) of EIS influential factors. This systematic process will also assist LGA decision-makers in better interpreting EIS and its underlying problems. The research reported herein should be of interest to both academics and practitioners who are involved in IOIS, in general, and collaborative e-Government, in particular.

Discrimination between the human prostate normal cell and cancer cell by using a novel electrical impedance spectroscopy controlling the cross-sectional area of a microfluidic channel

The prostate biopsy method shows a high false negative result because the suspicious tissue considered as cancer is not confirmed during tissue sampling. Thus, repeated biopsy procedures and diagnostic errors in relation to prostate cancer frequently occur. The purpose of this research is to enhance the prostate cancer detection rate by using microfluidic electrical impedance spectroscopy (μEIS), which allows real-time measurement of the electrical impedance of a single human prostate normal cell and cancer cell. The μEIS was equipped with a movable flexible membrane, which is operated by pneumatic pressure to capture the single cell on the surface of sensing electrodes. The forced tight contact between the cell and electrodes makes it possible to measure the electrical characteristics of the cell with a high sensitivity. The μEIS discriminates well between normal human prostate cells (RWPE-1) and cancer cells (PC-3) at 8.7 kHz based on the electrical signal responses of the cells. The average difference rates of admittance magnitude and susceptance are 54.55% and 54.59%, respectively. The developed μEIS also shows high repeatability, which was verified by a deionized water test conducted before and after each cell assay; the maximum variance of both the impedance and admittance at 8.7 kHz was as small as 9.48%.
