Seeing the big PICTURE: A framework for improving the communication of requirements within the Business-IT relationship

The relationship between the business and IT departments in the context of the organisation has been characterised as highly divisive. Contributing problems appear to revolve around the failure to adequately communicate and understand the required information for the alignment of business and IT strategies and infrastructures. This study takes a communication-based view on the concept of alignment, in terms of the relationship between the retail business and IT within a major high street UK bank. A research framework (PICTURE) is used to provide insight into this relationship and guide the analysis of interviews with 29 individuals on mid-high management level for their thematic content. The paper highlights the lessons that can be derived from the study of the BIT relationship and how possible improvements could be made

Early Appropriate Parenteral Antimicrobial Treatment of Complicated Skin and Soft Tissue Infections Caused by Methicillin-Resistant Staphylococcus aureus

Abstract Background: Complicated skin and soft tissue infections (cSSTIs) are a major clinical problem, in part because of the increasing resistance of infecting bacteria to our current antibiotic therapies. Prompt appropriate treatment of infections in hospitalized patients reduces the mortality rate. Furthermore, appropriate and timely antibiotic therapy improves outcomes for cSSTIs caused by methicillin-resistant Staphylococcus aureus (MRSA). This review delineates factors to consider in the choice of initial antibiotic treatment for cSSTIs and describes the antimicrobial agents available or under clinical development for the treatment of cSSTIs caused by MRSA. Methods: Review of the pertinent literature and recommendations. Results: The choice of antimicrobial agent for empiric treatment of cSSTIs should be guided by the site and type of infection, the presence of an immunocompromised state or neutropenia, and risk factors for hospital-acquired MRSA (HA-MRSA) or community-associated MRSA (CA-MRSA) infection. Most CA-MRSA strains remain susceptible to ciprofloxacin, clindamycin, gentamicin, and trimethoprim/sulfamethoxazole, although resistance to clindamycin can emerge during treatment. Of the agents available for the treatment of HA-MRSA cSSTIs, vancomycin has been the reference standard, but clinical failures have been reported increasingly. Alternative agents for HA-MRSA include linezolid, which has been well-studied for treatment of cSSTIs, as well as daptomycin and tigecycline. A number of antibiotic agents are undergoing clinical trials or are under development for the treatment of cSSTIs caused by MRSA. Conclusions: Severe and progressive cSSTIs should be treated promptly with appropriate antibiotic agents. The choice of agent should be guided by a number of factors, including suspected CA-MRSA or HA-MRSA infection. Available agents should be evaluated carefully for efficacy in the treatment of MRSA cSSTIs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/63135/1/sur.2008.063.supp.pd

Automatic Detection of Cortical Arousals in Sleep and their Contribution to Daytime Sleepiness

Cortical arousals are transient events of disturbed sleep that occur spontaneously or in response to stimuli such as apneic events. The gold standard for arousal detection in human polysomnographic recordings (PSGs) is manual annotation by expert human scorers, a method with significant interscorer variability. In this study, we developed an automated method, the Multimodal Arousal Detector (MAD), to detect arousals using deep learning methods. The MAD was trained on 2,889 PSGs to detect both cortical arousals and wakefulness in 1 second intervals. Furthermore, the relationship between MAD-predicted labels on PSGs and next day mean sleep latency (MSL) on a multiple sleep latency test (MSLT), a reflection of daytime sleepiness, was analyzed in 1447 MSLT instances in 873 subjects. In a dataset of 1,026 PSGs, the MAD achieved a F1 score of 0.76 for arousal detection, while wakefulness was predicted with an accuracy of 0.95. In 60 PSGs scored by multiple human expert technicians, the MAD significantly outperformed the average human scorer for arousal detection with a difference in F1 score of 0.09. After controlling for other known covariates, a doubling of the arousal index was associated with an average decrease in MSL of 40 seconds ($\beta$ = -0.67, p = 0.0075). The MAD outperformed the average human expert and the MAD-predicted arousals were shown to be significant predictors of MSL, which demonstrate clinical validity the MAD.Comment: 40 pages, 13 figures, 9 table

Inter-expert and intra-expert reliability in sleep spindle scoring

Objectives: To measure the inter-expert and intra-expert agreement in sleep spindle scoring, and to quantify how many experts are needed to build a reliable dataset of sleep spindle scorings. Methods: The EEG dataset was comprised of 400 randomly selected 115 s segments of stage 2 sleep from 110 sleeping subjects in the general population (57 ± 8, range: 42–72 years). To assess expert agreement, a total of 24 Registered Polysomnographic Technologists (RPSGTs) scored spindles in a subset of the EEG dataset at a single electrode location (C3-M2). Intra-expert and inter-expert agreements were calculated as F_1-scores, Cohen’s kappa (κ), and intra-class correlation coefficient (ICC). Results: We found an average intra-expert F_1-score agreement of 72 ± 7% (κ: 0.66 ± 0.07). The average inter-expert agreement was 61 ± 6% (κ: 0.52 ± 0.07). Amplitude and frequency of discrete spindles were calculated with higher reliability than the estimation of spindle duration. Reliability of sleep spindle scoring can be improved by using qualitative confidence scores, rather than a dichotomous yes/no scoring system. Conclusions: We estimate that 2–3 experts are needed to build a spindle scoring dataset with ‘substantial’ reliability (κ: 0.61–0.8), and 4 or more experts are needed to build a dataset with ‘almost perfect’ reliability (κ: 0.81–1). Significance: Spindle scoring is a critical part of sleep staging, and spindles are believed to play an important role in development, aging, and diseases of the nervous system

Progress in customer relationship management adoption: a cross-sector study

Although customer relationship management (CRM) is widely used by organizations to capture and manage customer data, the process of implementation can be problematic. This article takes a multi-sector view of CRM implementation in three areas of the UK services sector: banking and finance; professional services; and the government/public sector. The study captures variations in CRM practice and implementation across these sectors, applying an existing framework of CRM implementation to tease out progress in relation to people (the company's staff), the company itself, the customers, and the technology. The implications for organizations that have reached different implementation stages in their CRM journey are considered

State-of-the-art in product service-systems

A Product Service-System (PSS) is an integrated combination of products and services. This western concept embraces a service-led competitive strategy, environmental sustainability, and the basis to differentiate from competitors who simply offer lower priced products. This paper aims to report the state-of-the-art of PSS research by presenting a clinical review of literature currently available on this topic. The literature is classified and the major outcomes of each study are addressed and analysed. On this basis, this paper defines the PSS concept, reports on its origin and features, gives examples of applications along with potential benefits and barriers to adoption, summarises available tools and methodologies, and identifies future research challenges

Electronic submission and the movement towards a paperless law office in a modern university

The Government’s target of 50% of all under 30 year olds studying at higher education institutions by 2010, coupled with the National Committee Inquiry into Higher Education’ (1997) concluding that further expansion of higher education could not be afforded under the existing funding arrangements, may have serious ramifications for higher education in the UK. Alongside this increase in numbers, students are increasingly seen as educational consumers with increased choice in a demand-led market which universities must recognise. To compete in this academic environment these institutions are having to be ever more consumer aware in the services they offer and are having to increase choice to attract customers from rival enterprises. Information technology is playing an increasing role in the learning experience as noted by institutional commentators such as the Higher Education Funding Council for England, the Joint Information Systems Committee, the Electronic Books ON-screen Interface group and Lord Dearing’s Report. Technology’s use is further evidenced through institutions’ employment of the internet, e-mail and web-based learning to harness the power of this medium. This paper focuses on the concept of commercialism in the university sector and how a movement to a paperless office may be one way in which a university could gain an early competitive advantage over its rivals. The paper takes a student perspective to demonstrate whether students would wish to move towards electronic methods of submission of assessed work and considers the current problems that are encountered in physical submission of documents. This is the first paper in an on-going research project investigating the benefits and viability of a paperless law office, and the results demonstrate both that the students desire more flexibility in submission of university work and that their acceptance may be the easy first step on the road to the paperless law school

Association of maternal sleep practices with pre‐eclampsia, low birth weight, and stillbirth among Ghanaian women

ObjectiveTo assess sleep practices, and investigate their relationship with maternal and fetal outcomes, among pregnant Ghanaian women.MethodsIn a cross‐sectional study conducted at Korle Bu Teaching Hospital, Accra, Ghana, between June and July 2011, postpartum women were interviewed within 48 hours of delivery about sleep quality and practices during pregnancy. Interviews were coupled with a systematic review of participants’ medical charts for key outcomes including maternal hypertension, pre‐eclampsia, premature delivery, low birth weight, and stillbirth.ResultsMost women reported poor sleep quality during pregnancy. Snoring during pregnancy was independently associated with pre‐eclampsia (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.4–8.5; P = 0.007). The newborns of women who reported supine sleep during pregnancy were at increased risk of low birth weight (OR, 5.0; 95% CI, 1.2–20.2; P = 0.025) and stillbirth (OR, 8.0; 95% CI, 1.5–43.2; P = 0.016). Low birth weight was found to mediate the relationship between supine sleep and stillbirth.ConclusionThe present findings in an African population demonstrate that maternal sleep, a modifiable risk factor, has a significant role in pre‐eclampsia, low birth weight, and subsequently stillbirth.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135150/1/ijgo261.pd
