我国高校内部教学质量保障体系的界说、问题与调适

高校内部教学质量保障体系的核心要素是教学保障，而非监控和评价。以外控管理为主要价值取向的教学质量保障体系。在不自觉中会形成制约教学质量提高的制度性障碍。高校教学活动的复杂性、创造性和学术性，决定了高校专业教学人员不仅是教学质量保障体系的责任主体，更是教学质量保障体系的评价主体。

基于医疗质量实时监控系统的运行病历书写质量研究

目的:研究医疗质量实时监控系统是否可以提高运行病历的书写质量?方法:对实时监控前后共四年的运行病历书写质量进行回顾性分析,监控前共抽查960份运行病历,监控后检查24 255份运行病历,从运行病历书写的及时性?完整性?内涵质量三方面进行汇总分析?结果:监控前组和监控组比较,及时性达标率由79.4%提升到85.2%(P < 0.001),完整性达标率由94.9%提升到98.2%(P < 0.001),内涵质量达标率由91.8%提升到93.6%(P = 0.114);监控后第二年(2013年)发现运行病历书写及时性?完整性?内涵质量不达标情况分别集中在危重患者病程记录不及时?入院录不完整?日常病程记录内涵质量不高等方面;运行病历书写质量受书写人员的性别?学历?职称?科室因素影响?结论:医疗质量实时监控系统的应用是提高运行病历书写及时性?完整性的有效方法,但对提高运行病历书写的内涵质量效果不明显;女性?高职称?高学历?非手术科室的医务人员运行病历书写的质量较高?     

Monitoring and change-point estimation for spline-modeled non-linear profiles in phase II

In some applications of statistical quality control, quality of a process or a product is best characterized by a functional relationship between a response variable and one or more explanatory variables. This relationship is referred to as a profile. In certain cases, the quality of a process or a product is better described by a non-linear profile which does not follow a specific parametric model. In these circumstances, nonparametric approaches with greater flexibility in modeling the complicated profiles are adopted. In this research, the spline smoothing method is used to model a complicated non-linear profile and the Hotelling T² control chart based on the spline coefficients is used to monitor the process. After receiving an out-of-control signal, a maximum likelihood estimator is employed for change point estimation. The simulation studies, which include both global and local shifts, provide appropriate evaluation of the performance of the proposed estimation and monitoring procedure. The results indicate that the proposed method detects large global shifts while it is very sensitive in detecting local shifts.     

A Comparison of the Performance of Phase II Simple Linear Profile Control Charts when Parameters are Estimated

The standard deviation of the average run length (SDARL) is an important performance metric in studying the performance of control charts with estimated in-control parameters. Only a few studies in the literature, however, have considered this measure when evaluating control chart performance. The current study aims at comparing the in-control performance of three phase II simple linear profile monitoring approaches; namely, those of Kang and Albin (2000), Kim et al. (2003), and Mahmoud et al. (2010). The comparison is performed under the assumption of estimated parameters using the SDARL metric. In general, the simulation results of the current study show that the method of Kim et al. (2003) has better overall statistical performance than the competing methods in terms of SDARL values. Some of the recommended approaches based solely on the usual average run length properties can have poor SDARL performance.

Demand‐Side Challenges to Poverty Monitoring and Assessment Systems: Illustrations from Tanzania

Over the past decade, considerable attention and resources have been directed at Poverty Monitoring and Assessment Systems (PMASs), a core problem being the limited demand for, and use of, the data they generate. This article discusses the sources of these demand‐side problems and explores the difficulties in trying to address them via PMAS‐related processes, arguing that both institutional factors and design features have contributed to the disappointing performance of these systems. Incentive structures within the public sector in particular have made for an extremely unfavourable environment, and institutional problems have been compounded by questionable design features resulting from faulty analysis, flawed assumptions and conflicting views as to the objectives of ‘poverty monitoring’. Tanzania's PMAS experience is used to illustrate the argument.
