Purpose Global analyses using mean deviation (MD) assess visual field progression, but can miss localized changes. Pointwise analyses are more sensitive to localized progression, but more variable so require confirmation. This study assessed whether cluster trend analysis, averaging information across subsets of locations, could improve progression detection. Methods A total of 133 test-retes...

1. DEFINITIONS. Let D be the unit disk {z\ \z\ < l } and let £ be the group of conformai homeomorphisms of D. A Fuchsian group is a discrete subgroup of <£. We shall be concerned here with the finitely generated Fuchsian groups. It is known that these have the following presentations. Generators: aïy bi, • • • , ag, bg, eh • • • , ek, fa, • • • , hm, pu • * * , pr. Defining relations : e? = eg ...

INTRODUCTION The Quality Measurement Framework (QMF) programme is being funded for three years by the Treasury under Invest to Save and led by the Office of National Statistics (ONS). The aim of the QMF programme is to create entirely new mechanisms for more effective and efficient measurement and monitoring of third sector provision of public services, reducing the burden on the third sector w...

The definitions of θ-ray pattern matrix and θ-ray matrix are firstly proposed to establish some new results on nonsingularity/singularity and convergence of general H-matrices. Then some conditions on the matrix A ∈ Cn×n and nonempty α ⊂ 〈n〉 = {1, 2, . . . , n} are proposed such that A is an invertible H-matrix if A(α) and A/α are both invertible H-matrices. Furthermore, the important results o...

OBJECTIVES The aims were to characterize the movements in cervical dystonia (CD) by using an estimate of the mechanical power and work involved in the movements and to describe this through a movement energy index (MEI). MATERIALS AND METHODS The subjects (patients n = 6, controls n = 6) were seated in front of a screen with a laser pointer attached to a headband while they performed standard...

In recent years, regression testing has been receiving increasing attention. Several selective regression testing strategies have been introduced. One question that demands an answer is the cost benefits of the selective regression testing strategies compared to the traditional retest-all strategy. This paper first presents a test cost model and then identifies the conditions under which the se...

OBJECTIVE The purpose of this study was to assess the intrarater and interrater reliability of a broad range of techniques commonly used to assess the lower quarter. METHODS A test-retest single group design was used to investigate the intrarater and interrater reliability of 22 lower quarter evaluation measures. Two raters conducted each measure twice on a total of 18 unimpaired subjects wit...

BACKGROUND Valid instruments to measure practitioners' attitudes towards clinical practice guidelines need to be developed. However, few of the available instruments have been thoroughly validated. OBJECTIVE To adapt into French and to test the reliability and validity of a scale for measurement of attitudes towards guidelines developed by Elovainio et al. METHODS A 27-item scale (divided i...

BACKGROUND The reproducibility of a self-administered questionnaire on different epidemiological variables was examined in a random sample of a cohort of healthy women from the South Swedish Health Care Region. An identical questionnaire has previously been used for assessment of melanoma risk, in a population-based, matched, case-control study from the same region. METHODS Repeat questionnai...
