An Experimental Study in Reporting Pupil Progress Through Parent-Teacher Conferences as a Supplement to Report Cards in the Wishram, Washington, Elementary School

It was the purpose of this study to determine if the values derived from parent-teacher conferences used as a supplement to report cards would be worth while in the Wishram, Washington, Elementary School

To remember like a diplomat

To remember like a diplomatThis article investigates how a tight-knit group of multilateral economic diplomats – simply called the Europeans – retell their story of the shock of the Norwegian non-joining of the European Community (EC) in September 1972. Drawing on concepts from Paul Ricoeur and Iver B. Neumann, combining oral and archive-based history, this article argues that the Europeans have reconciled the ingrained heroic story of ‘the diplomat’ with the traumatic experience of the Norwegian ‘no’ by narrating themselves as martyrs metaphorically sacrificing themselves for a just cause. Rather than fundamentally changing their story – for example portraying themselves as failures – they elevate their cause to something unassailably virtuous: Peace in Europe

2D vs. 3D pain visualization: User preferences in a spinal cord injury cohort

This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2011 Springer VerlagResearch on pain experienced after Spinal Cord Injury (SCI) has revealed that not only are there several types of pain present in the same individual with this kind of trauma, but also that people who suffer such an injury can describe the characteristics of the same type of pain in different ways. Making it possible, therefore, to more precisely describe pain experience could prove to be vital for an increased quality of life. Accordingly, fifteen individuals with pain after SCI were asked to describe their pain experience using a 3 Dimensional (3D) model of the human body that could be used as an aid in communicating their pain. The results of this study suggest that the consensus of the participants approved the ability of the 3D model to more accurately describe their pain, an encouraging outcome towards the use of 3D technology in support of post SCI pain rehabilitation

Ergodic Jacobi matrices and conformal maps

We study structural properties of the Lyapunov exponent $\gamma$ and the density of states $k$ for ergodic (or just invariant) Jacobi matrices in a general framework. In this analysis, a central role is played by the function $w=-\gamma+i\pi k$ as a conformal map between certain domains. This idea goes back to Marchenko and Ostrovskii, who used this device in their analysis of the periodic problem

Spinal involvement in mucopolysaccharidosis IVA (Morquio-Brailsford or Morquio A syndrome): presentation, diagnosis and management.

Mucopolysaccharidosis IVA (MPS IVA), also known as Morquio-Brailsford or Morquio A syndrome, is a lysosomal storage disorder caused by a deficiency of the enzyme N-acetyl-galactosamine-6-sulphate sulphatase (GALNS). MPS IVA is multisystemic but manifests primarily as a progressive skeletal dysplasia. Spinal involvement is a major cause of morbidity and mortality in MPS IVA. Early diagnosis and timely treatment of problems involving the spine are critical in preventing or arresting neurological deterioration and loss of function. This review details the spinal manifestations of MPS IVA and describes the tools used to diagnose and monitor spinal involvement. The relative utility of radiography, computed tomography (CT) and magnetic resonance imaging (MRI) for the evaluation of cervical spine instability, stenosis, and cord compression is discussed. Surgical interventions, anaesthetic considerations, and the use of neurophysiological monitoring during procedures performed under general anaesthesia are reviewed. Recommendations for regular radiological imaging and neurologic assessments are presented, and the need for a more standardized approach for evaluating and managing spinal involvement in MPS IVA is addressed

A study of cleft lip/palate in a community in the South East of Ghana

The previous study in Wudoaba villages suggested that cleft lip and cleft palate (CL/CP) may be endemic in the Wudoaba cluster of villages in the Ketu South District of the Volta Region in South East Ghana. The study was to detect the prevalence of CL/CP in the Wudoaba communities and to investigate the factors associated with the causes of this malformation in the area. Two different interview-based questionnaires were designed to collect data over a period of 3 days from March 27 to 29, 2006. A purposive and accidental random sampling technique was used in the administering of the various questionnaires to the respondents. Data collected were recorded and analyzed with SPSS version 17.0. A total 99 respondents, with a mean age of 55.0 years, were interviewed. Out of it, 57.6% (n = 57) were related to their spouses: 54 first cousins and three other family relations. The prevalence of CL/CP is at least 6.3 per 1,000 people (i.e., 25/4,000). Majority (56.0%, n = 14) of the cleft cases were unilateral. Interviews revealed that genetic homogeneity and vitamin deficiencies in this community may be a causal factor for the high prevalence of CL/CP. This community provides clues suggesting that the magnitude of CL/CP may be larger than other studies and identifies the Wudoaba population as one that could be further studied to explore the underlying factors causing this congenital malformation

Impaction bone grafting of the acetabulum at hip revision using a mix of bone chips and a biphasic porous ceramic bone graft substitute: Good outcome in 43 patients followed for a mean of 2 years

Background and purpose One of the greatest problems of revision hip arthroplasty is dealing with lost bone stock. Good results have been obtained with impaction grafting of allograft bone. However, there have been problems of infection, reproducibility, antigenicity, stability, availability of bone, and cost. Thus, alternatives to allograft have been sought. BoneSave is a biphasic porous ceramic specifically designed for use in impaction grafting. BoneSave is 80% tricalcium phosphate and 20% hydroxyapatite. Previous in vitro and in vivo studies have yielded good results using mixtures of allograft and BoneSave, when compared with allograft alone. This study is the first reported human clinical trial of BoneSave in impaction grafting
