Electronic marking of mathematics assignments using Microsoft Word 2007

This paper describes on-going work within the Department of Mathematics and Statistics at The Open University to enable distance learning students to electronically submit assignments rich in mathematical notation and diagrams, and for those assignments to be marked and returned electronically by their tutor. A trial is currently underway of a prototype system that enables students to submit assignments in a range of electronic formats, which are then converted to Microsoft Word 2007 format to enable tutors to take advantage of various features of this software for marking and providing mathematical comments. The systems developed for this trial are described and preliminary findings presented

Perceptions of online tutorials for distance learning in mathematics and computing

We report on student and staff perceptions of synchronous online teaching and learning sessions in mathematics and computing. The study is based on two surveys of students and tutors conducted 5 years apart, and focusses on the educational experience as well as societal and accessibility dimensions. Key conclusions are that both staff and students value online sessions, to supplement face-to-face sessions, mainly for their convenience, but interaction within the sessions is limited. Students find the recording of sessions particularly helpful in their studies

Information Technology Issues in Healthcare: Hospital CEO and CIO Perspectives

Healthcare Information Technology (HIT) is widely regarded as a key to improving the quality of healthcare in the United States and potentially reducing its cost. Yet, its implementation is a continuous challenge for the healthcare industry. In this article, we report the results of a survey distributed to CEOs and CIOs at 1400 U.S. hospitals regarding their perceptions of the key information technology (IT) issues in healthcare. Among the top ten issues, the implementation of electronic medical records is ranked the highest. Included in the top ten are issues related to: improving healthcare quality by the use of information technology; change management, privacy, security, and accuracy of electronic records; and decision support applications. While some differences existed, we found much similarity between the views of the CEOs and the CIOs with both groups being characterized as conservative and risk-averse in their entrepreneurial orientation. No major differences were observed between urban and rural hospitals, or large and small hospitals. Given the heightened interest in healthcare IT, these results have wide implications for many stakeholders in this burgeoning industry

Mapping and explaining the productivity of Pinus radiata in New Zealand

Mapping Pinus radiata productivity for New Zealand not only provides useful information for forest owners, industry stakeholders and policy managers, but also enables current and future plantations to be visualised, quantified, and planned. Using an extensive set of permanent sample plots, split into fitting (n = 1,146) and validation (n = 618) datasets, models of P. radiata 300 Index (an index of volume mean annual increment) and Site Index (an index of height growth) were developed using a regression kriging technique. Spatial predictions were accurate and accounted for 61% and 70% of the variance for 300 Index and Site Index, respectively. Productivity predicted from these surfaces for the entire plantation estate averaged 27.4 m³ ha⁻¹ yr⁻¹ for the 300 Index and 30.4 m for Site Index. Surfaces showed wide regional variation in this productivity, which was attributable mainly to variation in air temperature and root-zone water storage from site to site

Are corticosteroid injections more beneficial than anaesthetic injections alone in the management of rotator cuff-related shoulder pain? A systematic review.

This is the accepted version of the following article: Tim Cook, Catherine Minns Lowe, Mark Maybury, and Jeremy S. Lewis, ‘Are corticosteroid injections more beneficial than anaesthetic injections alone in the management of rotator cuff-related shoulder pain? A systematic review’, British Journal of Sports Medicine, April 2018, which has been published in final form at http://dx.doi.org/10.1136/bjsports-2016-097444.

Design Systematic review with best evidence synthesis. Data sources The Cochrane, PubMed, CINAHL Plus, PEDro and EMBASE electronic databases were searched (inception until 8 June 2017). Reference lists of included articles were also hand searched. Eligibility criteria Two reviewers independently evaluated eligibility. Randomised controlled trials (RCTs) were included if they compared subacromial injections of corticosteroid with anaesthetic injections. Two reviewers independently extracted data regarding short-term, midterm and long-term outcomes for pain, self-reported function, range of motion and patient-perceived improvement. Results Thirteen RCTs (n=1013) were included. Four trials (n=475) were judged as being at low risk of bias. Three studies of low risk of bias favoured the use of corticosteroid over anaesthetic-only injections in the short term (up to 8 weeks). There was strong evidence of no significant difference between injection types in midterm outcomes (12-26 weeks). There was limited evidence of no significant difference between injection types in long-term outcomes. Conclusion Corticosteroid injections may have a short-term benefit (up to 8 weeks) over local anaesthetic injections alone in the management of RCRSP. Beyond 8 weeks, there was no evidence to suggest a benefit of corticosteroid over local anaesthetic injections. Trial registration number PROSPERO CRD42016033161.Peer reviewedFinal Accepted Versio

A review of the anticoagulant pesticide Pindone

A review of the use of pindone for rabbit control in Western Australia is timely due to increased public concern over the use of this toxin, and because non-target deaths of some native Australian animals have been known to occur following its use. Pindone is one of the first generation indandione anticoagulant rodenticides which were developed in the late 1940\u27 s. The toxicity of anticoagulants arises from their inhibition of vitamin K-dependent clotting factors in the blood. Thus therapeutic administration of vitamin K provides a reliable antidote against anticoagulant poisoning. Pindone is slow acting and works best with repeated small doses. Pindone also has insecticidal and fungicidal properties, and can act as a systemic insecticide (eg. fleas, lice and mosquitoes). The implications of the latter for the main vectors responsible for the transmission of myxomatosis are unknown.https://researchlibrary.agric.wa.gov.au/books/1010/thumbnail.jp

A soil-landscape model for Mahurangi Forest, Northland, New Zealand

Exotic plantation forestry is an important land use of both economic and environmental significance in Northland and elsewhere in New Zealand. It is therefore of considerable importance that forestlands be managed sustainably by employing approaches such as site-specific management. The establishment of site-specific forest management practices requires information regarding the distribution of key soil properties (Turvey and Poutsma, 1980). Quantitative modelling to predict key soil properties from landscape features may be an effective approach to mapping forestlands. A study investigating the efficacy of such an approach is being conducted within Mahurangi Forest, Northland, New Zealand. As a pilot to the study, a detailed qualitative soil-landscape model was developed in order to gain a greater understanding of the soil-landscape relationships and soil pattern of the area. The qualitative soil-landscape model developed in the pilot study is presented here

A soil-landscape model for southern Mahurangi Forest, Northland

Exotic plantation forestry has a productive area of about 75 000 ha in Northland (L. Cannon, personal communication). Forestry is thus an important land use of both economic and environmental significance in Northland as well as elsewhere in New Zealand. Therefore, it is of considerable importance that forestlands be managed sustainably by employing approaches such as site-specific management. The establishment of site-specific forest management practices requires information regarding the distribution of key soil properties (Turvey and Poutsma, 1980). Quantitative modelling to predict key soil properties of sustainable forestry from observable landscape features may be a cost-effective approach to mapping forestlands. We are investigating the efficacy of such an approach within Mahurangi Forest, Northland

Case of Nigeria-Acquired Human African Trypanosomiasis in United Kingdom, 2016.

Human African trypanosomiasis has not been reported in Nigeria since 2012. Nevertheless, limitations of current surveillance programs mean that undetected infections may persist. We report a recent case of stage 2 trypanosomiasis caused by Trypanosoma brucei gambiense acquired in Nigeria and imported into the United Kingdom
