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

男女比例失调原因探析 总被引:1,自引:0,他引:1
近年来亚洲许多国家面临男女比例失调的问题,这越来越受到有关国家甚至全世界的关注和重视。在中国,这个问题更为突出。男女比例失调在整个亚洲范围内,表面上看是由于亚洲的法律与文化对女性的轻视导致的,事实上导致男女比例失调的因素是多方面的。深入探究男女比例失调的原因,有助于为有效控制男女比例提供理论支持和政策导向。 相似文献

The Technical Vocational Education and Training (TVET) curriculum requires continuous renewal and constant involvement of stakeholders in the redesign process. Due to a lack of curriculum design expertise, TVET institutions in developing contexts encounter challenges maintaining and advancing the quality and relevance of their programmes to the needs of the labour market. The purpose of this multiple-case study is to describe the potential of teacher collaborative curriculum design (TCCD) in TVET colleges for improving the internal and external consistency of curricula. The study describes how four teams from different TVET college departments redesigned their programmes systematically and relationally to improve their internal and external consistency. The findings indicated that although the teams found the re-design task a challenge, they felt positive about the TCCD experience and its outcomes. The design teams also perceived the consistency of their programmes to have improved. The criticality of the support offered to the teams and the variety of the teams' design work were salient themes captured during the design process. It is concluded that supported TCCD teams, applying a systematic and relational approach, can be an efficient strategy for maintaining the consistency of the TVET curriculum. 相似文献

以A股上市公司为研究样本,研究高管和普通员工外部薪酬不公平性对公司绩效的影响。研究表明:随着外部薪酬不公平性的增加,公司绩效逐渐降低;与员工外部薪酬不公平性相比,这种现象对于高管更加严重;相对于非国有性质企业,外部薪酬不公平性对公司绩效的负面影响在国有企业中更加严重;随着企业发展前景的变好,公司净利润增长率的提高,外部薪酬不公平性对公司绩效的负面影响将越来越严重。 相似文献

关于我国外汇市场主要汇率的协整分析 总被引:3,自引:0,他引:3
自1973年布雷顿森林体系崩溃以来,世界外汇市场的汇率就表现出巨幅而且频繁波动的特征。由于外汇市场风险极大,因而要捕捉到汇率运动的规律就十分困难。目前,几家中国的商业银行推出了个人外汇买卖业务。本文着重对几种汇率之间的协整关系进行实证分析,以期发现它们之间是否存在长期的稳定的关系。其结果将有助于投资者制定决策并且有效地规避风险。 相似文献
