WHY JOHNNY CAN\u27T OR WON\u27T SPREADSHEET

This paper reports the results from a study on spreadsheet program use conducted in several departments within a city administration. Fourteen volunteer participants began the study by taking a two-day course on the spreadsheet program in question. The purpose of the project was to study spreadsheet program use longitudinally in a natural setting. That only three of the fourteen participants became spreadsheet program users made the question of why the others did not start using the spreadsheet program an interesting one. This paper explores the non-use phenomenon in the context of the spreadsheet program and focuses on four aspects: implementation, organizational support, the spreadsheet program package, and personal and task characteristics. The study suggests that different factors contribute to non-use

A Case Study of an Outsourcing Decision Project in a Large Public Organization

Phases in an outsourcing decision project are presented and critical issues are identified. First, there were different definitions of hosting and these different definitions made it unclear what the project was about and thereby the outcome of the project became unclear. This affected project commitment, project outcome project management, and project costs. Second, there were unclear descriptions of how the hosting was made in the organisation. The study suggests that had there been a clearer and more concise description of what the project was about and how the hosting was made a lot of the difficulties could have been avoided

Integrated Curriculum for a Bachelor of Science in Business Information Systems Design (BISD 2010)

Commentators on Information Systems (IS) education have urged the IS community to develop new and alternative IS curricula. The IS 2002 model curriculum has recently been revised. The new IS 2010 curriculum guidelines for undergraduate degree programs in Information Systems [Topi et al. 2010] has a curriculum structure to accommodate the education of several different professional roles within IS. This paper identifies one such role, the Business Information Systems Designer. It presents and argues for a new, integrated Bachelor of Science curriculum for Business Information Systems Design (BISD 2010) to educate for this role. The proposed curriculum focuses on the design and use of IS in business and has a strong design focus. The education focuses on developing and training a set of capabilities that enables the Business Information Systems Designer to participate in the design of business and IS in concert. Some examples of capabilities are communication and presentation skills, business and industry understanding, and high-level modeling. Consequently, the curriculum adopted a capabilities-driven pedagogical model in order to train specific skills. The paper presents the BISD 2010 with its specific expected learning outcomes, structure, and pedagogy, and also how the students should be able to fulfill the learning outcomes. The proposed curriculum differs from much of the current IS model curriculum discussions in a number of respects: (1) it is built on a notion of design, design science, and design as a profession, (2) it is based on a capability driven pedagogical model, (3) the curriculum is modeled for a European higher education context and the Bologna accord, and (4) it is not a model curriculum, but a specific, comprehensive, and ambitious curriculum for a degree program

The importance of comorbidity in analysing patient costs in Swedish primary care

BACKGROUND: The objective was to explore the usefulness of the morbidity risk adjustment system Adjusted Clinical Groups(® )(ACG), in comparison with age and gender, in explaining and estimating patient costs on an individual level in Swedish primary health care. Data were retrieved from two primary health care centres in southeastern Sweden. METHODS: A cross-sectional observational study. Data from electronic patient registers from the two centres were retrieved for 2001 and 2002, and patients were grouped into ACGs, expressing the individual combination of diagnoses and thus the comorbidity. Costs per patient were calculated for both years in both centres. Cost data from one centre were used to create ACG weights. These weights were then applied to patients at the other centre. Correlations between individual patient costs, age, gender and ACG weights were studied. Multiple linear regression analyses were performed in order to explain and estimate patient costs. RESULTS: The variation in individual patient costs was substantial within age groups as well as within ACG weight groups. About 37.7% of the individual patient costs could be explained by ACG weights, and age and gender added about 0.8%. The individual patient costs in 2001 estimated 22.0% of patient costs in 2002, whereas ACG weights estimated 14.3%. CONCLUSION: ACGs was an important factor in explaining and estimating individual patient costs in primary health care. Costs were explained to only a minor extent by age and gender. However, the usefulness of the ACG system appears to be sensitive to the accuracy of classification and coding of diagnoses by physicians

Luftföroreningar vid svetsning

PIXE-analyser kan utföras med utvecklad analysuppställning med noggrannhet och precision av c:a 10 % och med hög analyskapacitet. Ett dataprogram för evaluering av räntgenspektra presenteras.

Svetsaerosoler har karakteriserats m.h.a. PIXE, ESCA och TEM/EDAX. En uppställning för insamling av svetsaerosoler under utveckling och hittillsvarande resultat indikerar representativ provinsamling med god reproducerbarhet

Alpha-Photon Coincidence Spectroscopy Along Element 115 Decay Chains

Produced in the reaction 48Ca+243Am, thirty correlated α-decay chains were observed in an experiment conducted at the GSI Helmholzzentrum für Schwerionenforschung, Darmstadt, Germany. The decay chains are basically consistent with previous findings and are considered to originate from isotopes of element 115 with mass numbers 287, 288, and 289. A set-up aiming specifically for high-resolution charged particle and photon coincidence spectroscopy was placed behind the gas-filled separator TASCA. For the first time, γ rays as well as X-ray candidates were observed in prompt coincidence with the α-decay chains of element 115

Rare coding variants in PLCG2, ABI3, and TREM2 implicate microglial-mediated innate immunity in Alzheimer's disease

We identified rare coding variants associated with Alzheimer’s disease (AD) in a 3-stage case-control study of 85,133 subjects. In stage 1, 34,174 samples were genotyped using a whole-exome microarray. In stage 2, we tested associated variants (P<1×10-4) in 35,962 independent samples using de novo genotyping and imputed genotypes. In stage 3, an additional 14,997 samples were used to test the most significant stage 2 associations (P<5×10-8) using imputed genotypes. We observed 3 novel genome-wide significant (GWS) AD associated non-synonymous variants; a protective variant in PLCG2 (rs72824905/p.P522R, P=5.38×10-10, OR=0.68, MAFcases=0.0059, MAFcontrols=0.0093), a risk variant in ABI3 (rs616338/p.S209F, P=4.56×10-10, OR=1.43, MAFcases=0.011, MAFcontrols=0.008), and a novel GWS variant in TREM2 (rs143332484/p.R62H, P=1.55×10-14, OR=1.67, MAFcases=0.0143, MAFcontrols=0.0089), a known AD susceptibility gene. These protein-coding changes are in genes highly expressed in microglia and highlight an immune-related protein-protein interaction network enriched for previously identified AD risk genes. These genetic findings provide additional evidence that the microglia-mediated innate immune response contributes directly to AD development

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder
