Multidisciplinary Aspects of Design. Objects, Processes, Experiences and Narratives
The book addresses the contemporary perspectives of design on a multidisciplinary through 4 key words: objects, processes, experiences, narratives. It aims at further investigating the role of the archive for the design culture reflecting on âMemory and Futureâ and âThe Tools of Design and the Language of Representationâ, and also themes that are yet at the center of the multidisciplinary debate on design. The tenets of the conference (OPEN: objects, processes, experiences and narratives) will hence also correspond to the book sections:
-Objects. Design as focused on the object, on its functional and symbolic dimension, and at the same time on the object as a tool for representing cultures;
-Processes. The designerâs self-reflective moment which is focused on the analysis and on the definition of processes in various contexts, spanning innovation, social engagement, reflection on emergencies or forecasting.
-Experiences. Design as a theoretical and practical strategy aimed at facilitating experiential interactions among people, people and objects or environments.
-Narratives. Making history, representing through different media, archiving, narrating, and exhibiting design
Men, Work and Family life: a study of policy and practice in the UK and Italy
This paper documents the key themes emerging from a collaborative literature review on fatherhood and paid work, undertaken both in the UK and in Italy6. The aims and objectives of the review are to consider what âinvolved fatherhoodâ looks like and to identify the main factors that have been found to shape it. These are assessed against the prevalence of gendered structural and ideological constraints, which, on the one hand, bound the concept of âinvolvementâ, yet can conceal a much more nuanced, day-to-day reality on the other. The review is a comparative one, as far as this is possible, by evaluating the literature on fatherhood both in the UK and in Italy and is organised according to the themes that were found to be dominant throughout. Much of the literature has a UK focus. In Italy, while there is a growing academic focus on fatherhood, in the context of men and masculinity, the body of literature on this theme is scant compared to that on women and motherhood, and also compared to the international context. In particular, little research has been conducted on fatherhood and paid work: the workplace culture is typically considered from a legislative point of view (CalafĂ , 2004, 2007)
A method for the assessment of time-varying brain shift during navigated epilepsy surgery
Image guidance is widely used in neurosurgery. Tracking systems (neuronavigators) allow registering the preoperative image space to the surgical space. The localization accuracy is influenced by technical and clinical factors, such as brain shift. This paper aims at providing quantitative measure of the time-varying brain shift during open epilepsy surgery, and at measuring the pattern of brain deformation with respect to three potentially meaningful parameters: craniotomy area, craniotomy orientation and gravity vector direction in the images reference frame
Is panoramic radiography really a key examination before chemo-radiotherapy treatment for oropharyngeal cancer?
Aim: To evaluate the diagnostic accuracy of panoramic radiography (PAN) for the identification of infectious foci of the tooth and periradicular bone before definitive chemo-radiotherapy treatment for oropharyngeal cancer, using multislice spiral computed tomography (MSCT) imaging as the reference standard. Materials and methods: 50 patients with oropharyngeal cancer who had performed both pre-treatment MSCT and PAN were retrospectively evaluated. Pre-radiotherapy MSCT showed 65 deep caries, 37 root remnants, 143 stage III periodontal diseases, and 77 apical periodontitis, for a total of 322 infectious foci. The same number of healthy teeth (control group) was selected via MSCT to be analysed by PAN. Sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy for PAN images with respect to MSCT imaging were examined. Results: PAN showed sensitivity, negative predictive value, and diagnostic accuracy of 100% for deep caries, root remnants, and stage III periodontal disease, whereas there were 46.8%, 64.7%, and 72.1% apical periodontitis respectively. Conclusions: PAN did not show great diagnostic accuracy in the assessment of apical periodontitis, and therefore maxillofacial MSCT carried out before chemo-radiotherapy treatment should always be examined to identify dental and jaw diseases. Deep caries, root remnants, and stage III periodontal disease were perfectly detected on PAN
Identification of amyloidogenic light chains requires the combination of serum-free light chain assay with immunofixation of serum and urine
BACKGROUND: The diagnosis of systemic immunoglobulin light-chain (AL) amyloidosis requires demonstration of amyloid deposits in a tissue biopsy and armloidogenic monoclonal light chains. The optimal strategy to identify the amyloidogenic clone has not been established. We prospectively assessed the diagnostic sensitivity of the serum free light chain (FLC) kappa/lambda ratio, a commercial serum and urine agarose gel electrophoresis immunofixation (IFE), and the high-resolution agarose gel electrophoresis immunofixation (HR-IFE) developed at our referral center in patients with AL amyloidosis, in whom the amyloidogenic light chain was unequivocally identified in the amyloid deposits.
METHODS: The amyloidogenic light chain was identified in 121 consecutive patients with AL amyloidosis by immunoelectron microscopy analysis of abdominal fat aspirates and/or organ biopsies. We characterized the. monoclonal light chain by using IFE and HR-IFE in serum and urine and the FLC kappa/lambda ratio in serum. We then compared the diagnostic sensitivities of the 3 assays.
RESULTS: The HR-IFE of serum and urine identified the amyloidogenic light chain in all 115 patients with a monoclonal gammopathy. Six patients with a biclonal gammopathy were omitted from the statistical analysis. The diagnostic sensitivity of commercial serum and urine IFE was greater than that of the FLC kappa/lambda ratio (96% vs 76%). The combination of serum IFE and the FLC assay detected the amyloidogenic light chain in 96% of patients. The combination of IFE of both serum and urine with the FLC kappa/lambda ratio had a 100% sensitivity.
CONCLUSIONS: The identification of amyloidogenic light chains cannot rely on a single test and requires the combination of a commercially available FLC assay with immunofixation of both serum and urine. (C) 2008 American Association for Clinical Chemistr
