How to conduct External Quality Assessment Schemes for the pre-analytical phase?

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.

Validation of a videogrammetry technique for analysing American football helmet kinematics

ABSTRACT

Professional American football games are recorded in digital video with multiple cameras, often at high resolution and high frame rates. The purpose of this study was to evaluate the accuracy of a videogrammetry technique to calculate translational and rotational helmet velocity before, during and after a helmet impact. In total, 10 football impacts were staged in a National Football League (NFL) stadium by propelling helmeted 50th percentile male crash test dummies into each other or the ground at speeds and orientations representative of concussive impacts for NFL players. The tests were recorded by experienced sports film crews to obtain video coverage and quality typically available for NFL games. A videogrammetry procedure was used to track the position and rotation of the helmet throughout the relevant time interval of the head impact. Compared with rigidly mounted retroreflective marker three dimensional (3-D) motion tracking that was concurrently collected in the experiments, videogrammetry accurately calculated changes in translational and rotational velocity of the helmet using high frame rate (two cameras at 240 Hz) video (7% and 15% error, respectively). Low frame rate (2 cameras at 60 Hz) video was adequate for calculating pre-impact translational velocity but not for calculating the translational or rotational velocity change of the helmet during impact.     

‘And When did You Last See Your Father?’ Exploring the Views of Children with Learning Difficulties/Disabilities

The Gulliford Lecture 2003 was given by Professor Ann Lewis of the School of Education at the University of Birmingham. Professor Lewis's lecture, on which this article is based, focused on the process of listening to the views of children and, in particular, children with learning difficulties. Following the near-universal ratification of the United Nations (UN) Convention on the Rights of the Child, a plethora of recent initiatives, both in the UK and internationally, has encouraged professionals to access children's views about provision (educational, health-related, social and legal). A range of materials has been developed to support this process, often by, or in liaison with, children's charities. At the same time, research provides valuable insights into effective practice in exploring the views of children with learning difficulties. In this article, Ann Lewis reviews ten strategies for gathering the views of children and raises four challenges for the further development of policy and practice. She closes her argument with a call for greater rigour and critical evaluation in this crucial and demanding area.     

Changes that Occur in Families as Children with Intellectual Disability Grow Up

The effect on families and the changes that occur in relation to a child with disability or independently are considered through the life span. The recent advances in prenatal screening, special care baby units and genetic counselling may increase fear of disability and have not decreased the incidence. As the rest of the family grow older, the disabled child goes through school years, faces adult life, often with disappointments, and remains having special needs and specific vulnerability until old age.     

PLURALISTIC IGNORANCE AND THE CLIMATE OF OPINION IN A REAL-TIME DISASTER PREDICTION

This study employed a four-fold typology of opinion groups depictingthe relationships between minority–majority status andaccurate–inaccurate perception of the climate of opinionabout the 1990 prediction of a destructive earthquake for themid-United States New Madrid Seismic Zone. Data were collectedfrom 629 residents of the area where the earthquake was predictedto occur. Two frameworks were employed to define the climateof opinion to take into account two key variables that influencepublic response to earthquake predictions: the predication'sbelievability and its importance. Accurate perceptions of theclimate of opinion were differntiated from inaccurate perceptionsbased on more frequent media use and the confidence respondentsfelt about protecting themselves from potential earthquake damages.Inaccurate perceptions of the climate of opinion are differentiatednot by more extensive media use and discussions, but by thecrediability placed on the information from the news media anddiscussions, as well as the perceived influence of these informationsources.     

Government research evaluations and academic freedom: a UK and Australian comparison

Performance management systems have been an inevitable consequence of the development of government research evaluations (GREs) of university research, and have also inevitably affected the working life of academics. The aim of this paper is to track the development of GREs over the past 25 years, by critically evaluating their adoption in the UK and Australian higher education sector and their contribution to the commodification of academic labour, and to highlight the resultant tensions between GREs and academic freedom. The paper employs a literature-based analysis, relying on publicly available policy documents and academic studies over the period 1985–2010. GREs are a global phenomenon emanating from new public management reforms and while assessments of university research have been welcomed, they have attracted critique based on their design, the manner in which they have been applied, and the unintended consequences of their implementation on academic freedom in particular. Consistent with international research on the impact of GREs, Australian research assessments appear to be undoing the academic freedom that is central to successful research. Further empirical research on the impact of GREs on academics is urgently needed.     

This is what I’m doing and why: Methodological reflections on a naturalistic think-aloud study of interactive information behaviour

Many user-centred studies of electronic information resources include a think-aloud element – where users are asked to verbalise their thoughts, interface actions and sometimes their feelings whilst using these resources to help them complete one or more information tasks. These studies are usually conducted with the purpose of identifying usability issues related to the resource(s) used or understanding aspects of users’ information behaviour. However, few of these studies present detailed accounts of how their think-aloud data was collected and analysed or provide detailed reflection on methodological decisions made. In this article, we discuss and reflect on the methodology used when planning and conducting a think-aloud study of lawyers’ interactive information behaviour. Our discussion is framed by Blandford et al.’s PRET A Rapporter (‘ready to report’) framework – a framework that can be used to plan, conduct and describe user-centred studies of electronic information resource use from an information work perspective.
