Issues and Tensions in Island Heritage Management: A Case Study of Motuihe Island, New Zealand

This paper draws on a New Zealand case study, Motuihe Island, to examine the challenges of conserving cultural heritage in places renowned for natural heritage values. In keeping with the broader trend toward the ecological restoration of islands close to Auckland, Motuihe Island is undergoing conversion into an ecosystem of native flora and fauna. Issues and tensions relating to the management of natural and cultural heritage will be discussed and influencing aspects investigated: the nature/culture dualism, the effect of New Zealand’s history and identity, and the influence of islandness on heritage management

Graphs, Matrices, and the GraphBLAS: Seven Good Reasons

The analysis of graphs has become increasingly important to a wide range of applications. Graph analysis presents a number of unique challenges in the areas of (1) software complexity, (2) data complexity, (3) security, (4) mathematical complexity, (5) theoretical analysis, (6) serial performance, and (7) parallel performance. Implementing graph algorithms using matrix-based approaches provides a number of promising solutions to these challenges. The GraphBLAS standard (istc- bigdata.org/GraphBlas) is being developed to bring the potential of matrix based graph algorithms to the broadest possible audience. The GraphBLAS mathematically defines a core set of matrix-based graph operations that can be used to implement a wide class of graph algorithms in a wide range of programming environments. This paper provides an introduction to the GraphBLAS and describes how the GraphBLAS can be used to address many of the challenges associated with analysis of graphs.Comment: 10 pages; International Conference on Computational Science workshop on the Applications of Matrix Computational Methods in the Analysis of Modern Dat

Forage Bermudagrass: Selection, Establishment and Management

8 pp., 1 drawing, 6 tablesHybrid bermudagrass can produce high-quality forage, but as with any other crop, proper variety selection, soil preparation, planting, fertility, irrigation management, and timing of harvest are necessary to ensure the highest quality feed. This publication offers information on selecting the most suitable variety of bermudagrass; preparing the land; planting seed, sprigs, stolons, or tops; renovating bermudagrass fields; and managing and harvesting the crop

Nurse practitioner administered point-of-care ultrasound compared with X-ray for children with clinically non-angulated distal forearm fractures in the ED: A diagnostic study

Paediatric distal forearm fractures are a common ED presentation. They can be diagnosed with point-of-care ultrasound (POCUS) as an alternative to X-rays. Given that ED nurse practitioners (NPs) are relied on for the diagnosis of paediatric fractures, it is important to describe the diagnostic accuracy of NP-conducted POCUS versus X-ray.This prospective diagnostic study was conducted in a tertiary paediatric hospital in Queensland, Australia, between February 2018 and April 2019. Participants were children aged 4-16 years with a clinically non-angulated, suspected distal forearm fracture. Diagnosis from 6-view NP-administered POCUS of the distal radius and ulna was compared against the reference standard of 2-view X-ray. Each patient received both imaging modalities. Overall forearm diagnosis was classified as 'no', 'buckle' or 'other' fracture for both modalities. The primary outcome was diagnostic accuracy for 'any' fracture ('buckle' and 'other' fractures combined). Secondary outcomes included diagnostic accuracy for 'other' fractures versus 'buckle' and 'no' fractures combined, and pain, imaging duration and preference for modality.Of 204 recruited patients, 129 had X-ray-diagnosed forearm fractures. The sensitivity and specificity for NP-administered POCUS were 94.6% (95% CI 89.2% to 97.3%) and 85.3% (95% CI 75.6% to 91.6%), respectively. 'Other' fractures (mostly cortical breach fractures), when compared with 'buckle'/ 'no' fractures, had sensitivity 81.0% (95% CI 69.1% to 89.1%) and specificity 95.9% (95% CI 91.3% to 98.1%). Pain and imaging duration were clinically similar between modalities. There was a preference for POCUS by patients, parents and NPs.NP-administered POCUS had clinically acceptable diagnostic accuracy for paediatric patients presenting with non-angulated distal forearm injuries. This included good sensitivity for diagnosis of 'any' fracture and good specificity for diagnosis of cortical breach fractures alone. Given the preference for POCUS, and the lack of difference in pain and duration between modalities, future research should consider functional outcomes comparing POCUS with X-ray in this population in a randomised controlled trial

Emergency Alternative Crops for South Texas

8 pp., 2 tablesWhen hail, drought, flooding or untimely freezes destroy an established crop, planting an emergency alternative crop may be the producer's only hope for a profitable season. This publication helps producers determine which alternative crop is the best choice. Details are provided on soybeans, various types of peas, alyce clover, sorghums and other crops
