In laboratory medicine, several studies have described the most frequent errors in the different phases of the total testing process, and a large proportion of these errors occur in the pre-analytical phase. Schemes for registration of errors and subsequent feedback to the participants have been conducted for decades concerning the analytical phase by External Quality Assessment (EQA) organizations operating in most countries. The aim of the paper is to present an overview of different types of EQA schemes for the pre-analytical phase, and give examples of some existing schemes. So far, very few EQA organizations have focused on the pre-analytical phase, and most EQA organizations do not offer pre-analytical EQA schemes (EQAS). It is more difficult to perform and standardize pre-analytical EQAS and also, accreditation bodies do not ask the laboratories for results from such schemes. However, some ongoing EQA programs for the pre-analytical phase do exist, and some examples are given in this paper. The methods used can be divided into three different types; collecting information about pre-analytical laboratory procedures, circulating real samples to collect information about interferences that might affect the measurement procedure, or register actual laboratory errors and relate these to quality indicators. These three types have different focus and different challenges regarding implementation, and a combination of the three is probably necessary to be able to detect and monitor the wide range of errors occurring in the pre-analytical phase. 相似文献

Norway has seen major changes in the field of educational assessment over the past decade, following the 2001 ‘PISA shock’ that stimulated reform of the entire primary and secondary education systems: new outcome-based curricula with cross-disciplinary basic skills were accompanied by major revision of assessment regulations, comprehensive government projects promoting formative assessment, national tests as a main component in a new national quality assessment system and new regulations for examinations and teacher reporting of overall achievement marks. The paper provides a historical context to the country’s prohibition of formal marking in primary education and the recent tensions determining how assessment criteria should be stated and used for formative and summative purposes. It is argued that Norwegian primary and secondary education is riddled with unresolved tensions as to the role of assessment criteria and national tests, sparked by incremental implementation of assessment policies and principles accompanying the new outcomes-based curricula. 相似文献

It is commonly argued that we are witnessing a shift from global production networks, driven by the search for markets and lower cost production sites, to global innovation networks (GINs), driven by the search for knowledge. This paper explores how sources of behavioural differentiation derived from the literature on industrial knowledge bases and technological regimes condition the degree of involvement in international innovation collaboration. We find this to be significantly influenced by the nature of knowledge and the cumulativeness of knowledge development, the active use of measures to protect intellectual property, the inherent need to innovate and the opportunity to generate sales from this activity. The likelihood that the firm establishes and maintains a truly global network configuration is influenced accordingly. 相似文献

The aim of the paper is to examine the relationship between departmental attributes and university faculty research activity. Since individual and departmental factors are highly interrelated, individual attributes are included in a hierarchical linear model taking into consideration the nested structure of the data. Research activity is measured by research input in terms of time spent on research activities, and research output in terms of publications. The contextual factors have greatest impact on the indicator that is considered to be most essential when assessing research performance: published scientific articles. Department climate, age structure, as well as proportion of faculty members’ with PhD’s have significant impact on research output. 相似文献

In order to investigate how the use of robots may impact everyday tasks, twelve participants in our study interacted with a University of Hertfordshire Sunflower robot over a period of 8 weeks in the university's Robot House. Participants performed two constrained tasks, one physical and one cognitive, four times over this period. Participant responses were recorded using a variety of measures including the System Usability Scale and the NASA Task Load Index. The use of the robot had an impact on the experienced workload of the participants di?erently for the two tasks, and this e?ect changed over time. In the physical task, there was evidence of adaptation to the robot's behavior. For the cognitive task, the use of the robot was experienced as more frustrating in the later weeks. 相似文献
