A model to evaluate diabetes self-management programmes
No full textSelf-management has emerged as an approach to enhance quality of care for patients suffering from long term conditions, and to control costs of health services. So far, however, the effects of this approach as adopted by the Saudi healthcare system in the early 1990s remain unclear. Although current models define the concept of self-management, they do not provide a systematic development or an explanatory theory of how self management affects the outcomes of care. The objective of this research is to develop a framework applicable to the evaluation of self-management programmes. The evaluation model is built on patient-related intervention. The effectiveness of these interventions is determined by the levels of patient engagement and effective participation. Therefore, studying factors that influence patients‘ adherence to self-management activities is crucial to explain the outcomes of these interventions. We apply this framework to the case of diabetes mellitus, one of the most common chronic conditions in Saudi Arabia, causing huge burdens on patients and healthcare providers.A non-experimental retrospective cross-sectional survey research design has been employed to conduct this research using a self-administered questionnaire. Closed-ended questions were used to measure all study variables related to model construction. One open-ended question was used to investigate barriers to diabetes self-management. A non-probability convenient sample design was used to select diabetes centres participated in this study and a systematic approach for selecting patients in these centres. Research data were collected from five diabetes centres and clinics in the main five regions in Saudi Arabia. Quantitative data were analysed using simple, multiple and logistic regressions, whereas a directed content analysis approach was used to analyse qualitative data.The results of this study revealed that diabetes self-management improves clinical outcomes and reduces utilization of health services. The theoretical approaches underpinning self-management were based on established models from the field of health psychology. By investigating the effect of self-efficacy patients‘ beliefs, and locus of control on self-management, we found that these behavioural theories support the core assumptions of self-management. Self-efficacy was the most significant predictor of self-management followed by patient beliefs. Social support, effective communication between patients and health providers in addition to diabetes knowledge were all important factors to positively influence diabetes self-management. However a new construct, misconception of fatalism from the Islamic point of view, was found to play a negative role in diabetes management. The research model also suggests that diabetes knowledge was influenced by several factors. Education level was the most significant predictor of diabetes knowledge followed by age and diabetes education. It was also found that group education improves diabetes knowledge more than individual education.This model is a valid tool that could be used to evaluate self-management programmes in other chronic diseases. It can be used as a decision making supporting tool; to identify different components of self-management interventions, and to compare outcomes of programmes. It can also be used to group patients into different categories to facilitate providing tailored services suitable for each group. It could assist health providers to plan new interventions or to refine existing ones by allocating efforts and financial resources toward the most influential factors that affect patients‘ adherence to self-management activities.<br/
Collaborative digital library of historical resources : Evaluation of first users
No full textThis paper describes the digital library of historical resources, a research project which involves building a testbed for the purpose of developing and testing new collaborative digital library functionality and presents an initial analysis of the digital library's public use on the web. The digital library is modeled to focus on serving secondary students information needs in conducting history projects. As such, in the implementation of the digital library, the use of online resources would be an integral part of history project based learning activities. Students should be enabled to access digital resources, create and publish their own documents in the digital library and share them with others. As a testbed system, the collaborative digital library known as CoreDev has demonstrated its capabilities in serving an educational community as has been reflected by the positive feedback on the functional requirements from 44 users. Over 75 of the respondents in the user survey considered themselves capable of using the digital library easily. The beta tester demographics (n = 105) indicate that the digital library is reaching its target communities

No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Polymersomes with asymmetric membranes and self-assembled superstructures using pentablock quintopolymers resolved by electron tomography
No full textPolystyrene-block-poly(1,4-isoprene)-block-poly(dimethyl siloxane)-block-poly(tert-butyl methacrylate)-block-poly(2-vinyl pyridine), PS-b-PI-b-PDMS-b-PtBMA-b-P2VP, self-assembles in acetone into polymersomes with asymmetric (directional) PI-b-PDMS membranes. The polymersomes, in turn, self-assemble into superstructures. Analogically to supravesicular structures at a smaller length scale, we refer to them as suprapolymersome structures. Electron tomograms are shown to be invaluable in the structural assessment of such complex self-assemblies.J. S. Haataja, N. Houbenov and O.

The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals

Investigation of N-polar InGaN growth on misoriented ScAlMgO4 substrates
No full textWe report the growth of N-polar InGaN layers on misoriented ScAlMgO4 (SAM) substrates with offset of 0.3 to 5.8° toward the m-plane. The surface of N-polar InGaN with small-offset substrates exhibited hexagonal hillocks similar to those commonly observed in N-polar GaN layers. Larger misorientation angles resulted in smoother surfaces of the InGaN layers. In contrast, the crystalline quality of InGaN indicated an opposite trend with significantly improved quality observed at smaller misorientation angles. We obtained an unprecedented crystalline quality of N-polar InGaN using SAM substrates with a 0.5° offset, which exhibited a 0002 X-ray rocking curve full width at half maximum value of 223 arcsec. The crystalline quality and surface morphology of InGaN were significantly influenced by the step surface of substrates according to atomic force microscopy observations.This work was supported by the King Abdullah University of Science and Technology (KAUST) Research Funding (KRF) (Award Nos.
