An Excel Add-In for Statistical Process Control Charts  [PDF]
Samuel E. Buttrey
Journal of Statistical Software , 2009,
Abstract: t shifts in processes in, for example, manufacturing. Among these are control charts".Control charts and other SPC techniques have been in use since at least the 1950s, and,because they are comparatively unsophisticated, are often used by management or op-erations personnel without formal statistical training. These personnel will often haveexperience with the popular spreadsheet program Excel, but may have less training on amainstream statistical package. Base Excel does not provide the ability to draw controlcharts directly, although add-ins for that purpose are available for purchase.We present a free add-in for Excel that draws the most common sorts of control charts.It follows the development of the textbook of Montgomery (2005), so it may be well-suited for instructional purposes.
How often do physicians review medication charts on ward rounds?
Khang Li Looi, Peter N Black
BMC Pharmacology and Toxicology , 2008, DOI: 10.1186/1472-6904-8-9
Abstract: An observer noted how often consultant physicians at Auckland City Hospital reviewed medication charts during ward rounds. The physicians were not aware that they were being observed.Twenty-one physicians were observed over a 26 week period. The general physicians reviewed the medication charts on 77% of occasions (range: 45% – 100%) during routine ward rounds and 65% of the time (range: 41% – 80%) on post admission rounds. Subspecialty physicians who did not see more than 8 patients on their rounds reviewed medication charts more frequently (88%) than those specialties where more than 8 patients were seen on average (61%).The physicians did not review medication charts on all ward rounds and there was considerable variation in how often they did this. There is some evidence that the frequency with which charts are reviewed decreases as the number of patients seen increases. More efforts should be made to encourage regular review of medication charts.Prescribing errors are common in the hospital. In different studies adverse drug events have been reported to occur in 0.7% to 6.5% of hospital admissions [1]. 28% to 56% of these adverse drug events were thought to be preventable [2]. Bates et al estimated that each preventable adverse event leads to an additional cost of US $4,685 and increase in the length of stay of 4.6 days [3]. A number of interventions have been proposed to reduce medication errors including regular review of medication charts by doctors on ward rounds [2]. A case can be made for consultant staff to review all of the medication charts on every ward round that they go on. There is evidence that consultants make fewer prescribing errors than their junior medical staff [4,5] and they are well placed to detect errors made by the junior medical staff. If they review medication charts on each ward round it also emphasizes the importance of doing this to the junior medical staff. However we are not aware of any previous studies that document how often c
LICSS - a chemical spreadsheet in microsoft excel
Kevin R Lawson, Jonty Lawson
Journal of Cheminformatics , 2012, DOI: 10.1186/1758-2946-4-3
Abstract: LICSS is a lightweight chemical spreadsheet within Microsoft Excel for Windows. LICSS stores structures solely as Smiles strings. Chemical operations are carried out by calling Java code modules which use the CDK, JChemPaint and OPSIN libraries to provide cheminformatics functionality. Compounds in sheets or charts may be visualised (individually or en masse), and sheets may be searched by substructure or similarity. All the molecular descriptors available in CDK may be calculated for compounds (in batch or on-the-fly), and various cheminformatic operations such as fingerprint calculation, Sammon mapping, clustering and R group table creation may be carried out.We detail here the features of LICSS and how they are implemented. We also explain the design criteria, particularly in terms of potential corporate use, which led to this particular implementation.LICSS is an Excel-based chemical spreadsheet with a difference:? It can usefully be used on sheets containing hundreds of thousands of compounds; it doesn't compromise the normal performance of Microsoft Excel? It is designed to be installed and run in environments in which users do not have admin privileges; installation involves merely file copying, and sharing of LICSS sheets invokes automatic installation? It is free and extensibleLICSS is open source software and we hope sufficient detail is provided here to enable developers to add their own features and share with the community.The familiar Chemical Spreadsheet paradigm is an extremely useful way of presenting structural information together with calculated or measured structural properties. Indeed, most software which handles or stores chemical data will make available a tabular view implementing at least some of the more common spreadsheet functionality such as sorting by columns. Many excellent chemical spreadsheet tools are commercially available and there are also notable freeware/open source examples [1]. Most such software is self-contained which, of

Perspectivas em Gest?o & Conhecimento , 2012,
Abstract: A nova organiza o se redesenha menos centralizadora e mais inspiradora de estratégias, valores e competências. Perfil em transi o, que exige maior disposi o para o aprendizado, de forma a responder aos seguintes questionamentos: Qual o modelo para a excelência da organiza o na sociedade do conhecimento? Quais os fundamentos teóricos para orientar os processos e suprir lacunas na gest o? Quais os ativos intangíveis que definem as estratégias para a competitividade e agregam valor aos processos de gest o? Visando responder a estas quest es, este artigo estabelece elos conceituais entre os pressupostos teóricos que sustentam o Programa de Pós-Gradua o em Engenharia e Gest o do Conhecimento da Universidade Federal de Santa Catarina e, os fundamentos que alicer am o modelo de excelência da gest o, propostos pela Funda o Nacional de Qualidade. Em adi o, s o analisados os ativos intangíveis, a fim de compreender os processos de gest o como indicadores da excelência das organiza es. Conclui-se, que n o existe uma defini o cientificamente consensual sobre essa temática, pois as variáveis que interferem s o múltiplas. Por outro lado, as teoriza es permitem inferir que o conhecimento emana do processo de aprendizagem e do envolvimento das pessoas. Portanto, a Gest o do Conhecimento constitui-se na ancora estratégica para a competitividade organizacional.
Knowing and Guessing: How do 9 year olds approach the meaning of visual signs in weather charts?  [PDF]
Maria Papadopoulou
Meta-Carto-Semiotics , 2009,
Abstract: Weather charts in the popular media constitute a specific field of semiosis, meaning that they allow procedures of production and transfer of information by means of visual signs which, unlike other semiotic systems, are not firm and standard. The article deals with the ways 9 year old children interpret visual signs appearing on a website for weather predictions. The hypothesis of the research was that in order to interpret these visual signs correctly, the children have to reveal the semiotic system they are part of and then, discover the semiotic principles behind the formation of every sign or group of signs. As visual signs appearing at weather charts may be hypo-icons, indexes or symbols – regarding the relation they have to their dynamic objects – , the children's correct sign interpreation has to be based on the resemblance, the causality or contiguity and the symbolic value of the signs, correspondingly. Visual language is not always transparent and universally understood; therefore, children should be trained into it at school as part of the development of their general visual literacy.
