Calibration of measuring equipment is conducted by following some normative or applicable documents such as standards, manufacturer manuals and instructions, technical orders issued by defense organizations, or scientific papers. An accreditation body provides its recognition to the calibration laboratories by evaluating their technical competence and their compliance with the quality requirements of ISO/IEC 17025. The accreditation body must have defined criteria in order to evaluate different calibration methods which should ensure that the laboratories are performing the calibration in a technically competent manner when they are fully or even only partially based on the relevant reference documents. A discussion with different points of view about choosing the criteria, as well as the Israel Laboratory Accreditation Authority (ISRAC) policy on this issue, are presented.

Many decades after the introduction of ICT into classrooms there are still unanswered questions about the impact of technology in the long and short term on students' learning, and how it has affected simple and complex learning tasks. These are important for (a) forming government policies; (b) directing teacher education programmes: (c) advancing national curricula; (d); designing or reforming classroom implementation and (e) analysing costs and benefits. While a plethora of studies has been conducted on the effects of ICT in education, major policy and methodological problems have precluded an unambiguous answer to such questions as:—"Does the way in which ICT is implemented have a major/minor impact on students' knowledge and understanding?" and "Does the impact affect the surface or deep structure of students' thinking and acting?" To date we have had no large-scale longitudinal studies of ICT's impact in education such as we have in the form of studies of earlier major curriculum development projects. Nor have we had many comprehensive studies of the complex interactions between various types of ICT implementation and the effects of other factors such as school-based interventions, socio-economic status and school expenditures which have been shown to have a greater impact on education compared with other previous innovations in education. Furthermore we do not know if previous research studies have used research methods that matched learning objectives to instruments/procedures. Many previous studies are vague as to the actual measures used but we can infer that standardized tests were a frequent measure. In other instances, ad hoc analyses, with criteria that may have varied from analyst to analyst and were not "blind" analyses were certainly used to measure "success." All of these limitations and uncertainties and many more point to the need for a thorough, rigorous, and multifaceted approach to analysing the impact of ICT on students' learning. This paper draws on previous research evidence to identify relevant research strategies to address the gaps in our knowledge about ICT and students' learning explained above.

This article makes a case for the urgent need to improve health care quality and reduce costs. It provides an overview of the importance of the quality movement and the definition of quality, including the concept of clinical and operational quality. Some national drivers for quality improvement as well as drivers of escalating health care costs are discussed, along with the urgency of reducing health care costs. The link between quality and cost is reviewed using the concept of value in health care, which combines quality and cost in the same equation. The article ends with a discussion of future directions of the quality movement, including emerging concepts, such as risk-adjustment, shared responsibility for quality, measuring quality at the individual provider level, and evolving legal implications of the quality movement, as well as the concept of a shared savings model.
