Building user commitment to implementing a knowledge management strategy

In the IS literature, commitment is typically considered to involve organizational or managerial support for a system and not that of its users. This paper however reports on a field study involving 16 organizations that attempted to build user involvement in developing a knowledge management strategy by having them design it. Twenty-two IT-supported group workshops (involving 183 users) were run to develop action plans for better knowledge management that users would like to see implemented. Each workshop adopted the same problem structuring technique to assist group members develop a politically feasible action plan to which they were psychologically and emotionally dedicated. In addition to reviewing the problem structuring method, this paper provides qualitative insight into the factors a knowledge management strategy should have to encourage user commitment. © 2004 Elsevier B.V.

Analysis of nocturnal oxygen saturation recordings using kernel entropy to assist in sleep apnea-hypopnea diagnosis

In this study, a new entropy measure known as kernel entropy (KerEnt), which quantifies the irregularity in a series, was applied to nocturnal oxygen saturation (SaO 2) recordings. A total of 96 subjects suspected of suffering from sleep apnea-hypopnea syndrome (SAHS) took part in the study: 32 SAHS-negative and 64 SAHS-positive subjects. Their SaO 2 signals were separately processed by means of KerEnt. Our results show that a higher degree of irregularity is associated to SAHS-positive subjects. Statistical analysis revealed significant differences between the KerEnt values of SAHS-negative and SAHS-positive groups. The diagnostic utility of this parameter was studied by means of receiver operating characteristic (ROC) analysis. A classification accuracy of 81.25% (81.25% sensitivity and 81.25% specificity) was achieved. Repeated apneas during sleep increase irregularity in SaO 2 data. This effect can be measured by KerEnt in order to detect SAHS. This non-linear measure can provide useful information for the development of alternative diagnostic techniques in order to reduce the demand for conventional polysomnography (PSG). © 2011 IEEE.

Deconstructing phonological tasks:the contribution of stimulus and response type to the prediction of early decoding skills

Abstract Phonological tasks are highly predictive of reading development but their complexity obscures the underlying mechanisms driving this association. There are three key components hypothesised to drive the relationship between phonological tasks and reading; (a) the linguistic nature of the stimuli, (b) the phonological complexity of the stimuli, and (c) the production of a verbal response. We isolated the contribution of the stimulus and response components separately through the creation of latent variables to represent specially designed tasks that were matched for procedure. These tasks were administered to 570 6 to 7-year-old children along with standardised tests of regular word and non-word reading. A structural equation model, where tasks were grouped according to stimulus, revealed that the linguistic nature and the phonological complexity of the stimulus predicted unique variance in decoding, over and above matched comparison tasks without these components. An alternative model, grouped according to response mode, showed that the production of a verbal response was a unique predictor of decoding beyond matched tasks without a verbal response. In summary, we found that multiple factors contributed to reading development, supporting multivariate models over those that prioritize single factors. More broadly, we demonstrate the value of combining matched task designs with latent variable modelling to deconstruct the components of complex tasks.

Regularity analysis of nocturnal oximetry recordings to assist in the diagnosis of sleep apnoea syndrome

The relationship between sleep apnoea–hypopnoea syndrome (SAHS) severity and the regularity of nocturnal oxygen saturation (SaO2) recordings was analysed. Three different methods were proposed to quantify regularity: approximate entropy (AEn), sample entropy (SEn) and kernel entropy (KEn). A total of 240 subjects suspected of suffering from SAHS took part in the study. They were randomly divided into a training set (96 subjects) and a test set (144 subjects) for the adjustment and assessment of the proposed methods, respectively. According to the measurements provided by AEn, SEn and KEn, higher irregularity of oximetry signals is associated with SAHS-positive patients. Receiver operating characteristic (ROC) and Pearson correlation analyses showed that KEn was the most reliable predictor of SAHS. It provided an area under the ROC curve of 0.91 in two-class classification of subjects as SAHS-negative or SAHS-positive. Moreover, KEn measurements from oximetry data exhibited a linear dependence on the apnoea–hypopnoea index, as shown by a correlation coefficient of 0.87. Therefore, these measurements could be used for the development of simplified diagnostic techniques in order to reduce the demand for polysomnographies. Furthermore, KEn represents a convincing alternative to AEn and SEn for the diagnostic analysis of noisy biomedical signals.

Engaging future engineers:pedagogy, policy & practice

Despite being frequently misrepresented as outdated or old fashioned (IMechE, 2009, p1), engineering is increasingly called upon to deal with some of societies biggest challenges including those associated with climate, infrastructure and security. In order to meet such challenges there needs to be a supply of engineering talent able to turn its collective mind to what is required. Yet at a time when demands for engineers able to provide innovative solutions to contemporary problems is possibly at its highest, the profession is plagued by shortages and an inability to attract young people (DIUS, 2008; RAE 2008; NSF, 2009). Although the current situation appears critical, potential future shortages of engineers means that unless action is taken urgently, matters will get worse during the next 20 to 30 years. For higher education, the challenge is how to change young peoples perceptions of engineering in such a manner that it is seen as a worthwhile and rewarding career. This paper considers this challenge, looking in detail at why young people fail to view engineering positively. A theoretical framework outlining the various real-life barriers and drivers is proposed. A critical analysis of current policy and practice suggests that in order to promote engineering as a profession that young people want to enter, both pedagogic and policy grounded solutions need to be found. By bringing together pedagogy and policy within an engineering framework the paper adds to current debates in engineering education whilst providing a distinctive look at what seems to be a recurring problem. © 2009 Authors.

Do pharmacy graduates possess the necessary professional skills?

Background - Expansion of the pharmacists' role within the United Kingdom has raised the question as to whether pharmacy graduates are equipped with the professional skills and attributes they will need to fulfil such roles. Aim - To describe the professional skills and attributes pre-registration recruiters perceive pharmacy graduates should exhibit and to establish whether final year students perceive they possess these skills and attributes. Method - Five individuals were interviewed from a variety of pre-registration employers; 90 final year students completed a questionnaire (response 69.2%). Results - The recruiters thought that whilst graduates possess sufficient knowledge, they show weaknesses such as inability to apply theoretical knowledge into practice and the lack of good communication and interpersonal skills. Conversely, a majority of students felt that they did possess the necessary skills to enter pre-registration training. Conclusion - Schools of pharmacy need to ensure that students have an opportunity to develop key professional skills to assist students in securing pre-registration positions. © 2010 FIP.

Specialist business skills of international students

This paper follows on from that presented at the last BEST conference in Edinburgh (Higson & Hamilton-Jones(2004)). At that stage, the authors outlined their initial research work with students studying on the yearlong International Foundation programmes. at three local FE Colleges allied to Aston University. The research (funded by the University's Teaching Quality Enhancement Funds (TQEF) involved questionnaires and interviews with staff and students (the latter all from overseas). it aimed to identify ways to improve the learning experience of students on the International Foundation programmes, to aid their smooth transition to full degree programmes in Business and Management and to improve the progression rates of such students while studying at Aston. The initial research findings were used to design a module for those students' progress to degree programmes in Aston Business School. This paper discusses how the module was designed, its content and the assessment methods used to help determine whether students are achieving the learning outcomes. The basic principle was to identify areas of study where the International Foundation Programme students needed help in order to improve their learning styles to assist them with the requirements of other modules that they would be studying during their time at Aston. Particular emphasis was put on the need to develop active learners who were not disadvantaged by their lack of awareness of UK culture and society and who were as comfortable performing written work under examination conditions or presenting orally as their UK counterparts. An additional aim was to prepare these students for the placement year which was a compulsory part of their degree. The module, therefore, comprises a range of inputs for a number of staff, a company visit, weekly reflective learning leading to Personal Development Plan (PDP) work, formal examinations, presentations, group work •and individual case studies. This paper also reports on the initial reaction of the students and tutors to the new learning experience with currently 30 participants undertaking the module. Provisional findings suggest that the International Foundation programme has prepared the students well for degree-level work and that as a group of international students they are much more analytical and, after studying the module interactive than their counterparts who have come directly onto Aston degrees. It has shown them still to be quite passive learners, comfortable with facts and lecture-style learning environments, but less comfortable when asked to use their own initiatives. Continuing progress needs to be made in terms of encouraging them to develop a reflective approach to learning with the students taking some time to feel comfortable with an analytical approach to learning. In addition, im account of the students' reactions to having to work through a formal (PDP) and the results of their first assessments will be provided. At Aston, this work is being used as a pilot to recognise good practice with regards to work with further groups of international students. it is hoped that this would have widespread application across the sector.
