Action Research is Similar to Design Science 总被引:2,自引:0,他引:2
Pertti Järvinen 《Quality and Quantity》2007,41(1):37-54
In management information systems (MIS) action research is long considered as promising but low-level research approach. It
has an utmost relevance because action researchers are working with practitioners to solve the important practical problem.
Design science outlined some years ago is just winning a wider audience. Action research was traditionally classified into
qualitative research methods. But it seems to be the “wrong” home of action research. We shall show that after comparison
of the seven aspects: concrete results of the study, knowledge produced, activities, the intent and the nature of a study,
the division of labor in a study and generation, use and test of knowledge, the concordance between the characteristics of
action research on the one hand and of design science on the other hand is very good. Hence, action research and design science
should next be considered as similar research approaches, and this is a turning point in the history of both action research
and design science. 相似文献

When testing for the equality of two distributions in a case-control design with treatment effects presumed to act possibly
on more than one aspect, different tests may be properly considered for testing for different features of a null hypothesis,
leading to the multiple aspect testing issue. Two different aspects are therefore of interest: the location-aspect, based
on the comparison of location indexes, and the distributional-aspect, based on the comparison of the empirical distribution
functions. A simulation study shows that the combined testing procedure exhibits a good robust overall performance, and an
application in biomedical research is also presented. 相似文献

Linking performance drivers in production planning and inventory control to process choice 总被引:1,自引:0,他引:1
This study investigates how process choice relates to production planning and inventory control decisions. We empirically examine the validity of deductively derived patterns about these types of decisions. More importantly, we look for normative insights by exploring how production planning and inventory control decisions affect operations performance. Our findings show that production line and continuous flow plants use more of a level production strategy, and carry less raw material and work-in-process inventory. The performance drivers for these plants, through which the operations function excels, are effective utilization of equipment, reduced finished goods inventory, and reduced setup down time. To gain forward demand visibility and batching economies, job and batch shops rely much more on backlogs in their planning process. These plants use more of a production chase strategy and position inventory lower in the bills of materials. Four performance drivers for top-performing job and batch shops are to find ways that better anticipate customers' orders, have a more responsive chase strategy, carry less raw material or purchased inventory, and shorten production planning horizon, partly through less reliance on backlogs. It is intriguing that top-performing plants not only do the expected things, given their choice of process, but also excel in selected dimensions—some of which fit the profile normally associated with a different process choice. To monitor and continuously improve operations, evaluation ‘scorecards’ should pay particular attention to performance drivers, which change depending on the plant's process choice. 相似文献

The block sizes may be larger than the number of treatments. The results are applied to BBDs, reinforced BIBDs and BBDs, BTIBDs, and a series of variance balanced incomplete block designs with two block sizes. Also given for most of these designs, are results fort

为实现对多科性医院大数据治理水平的分析和评估,在数据管理成熟度模型和能力成熟度模型基础上,构建多科性医院大数据治理能力成熟度评价模型。将医院大数据治理能力成熟度分为初始级、程序级、规范级、管理级和优化级五个等级,基于医院内部大数据治理特征,建立包括三级指标的成熟度评价指标体系。然后,分别用客观赋权法及组合赋权法确定各指标权重,并结合未确知测度理论和评价方法,量化评估两个三甲多科性医院大数据治理能力的成熟度。结果表明,两种赋权方法下两家医院的大数据治理能力水平均处于规范级,与两家医院大数据治理的实际情况相吻合。未确知测度理论与信息熵权相结合,可以平衡指标测量主观性和评价结果稳定性,建立的模型能为多科性医院大数据治理提供具有参考价值的决策信息。 相似文献
