Creating traceability through the use of links between paragraphs of documents, or between objects in a requirements database, is a great step forward for many systems engineering organisations. It enables analysis of impact, coverage and derivation to be performed, and greatly improves the requirements management process. However, the semantics of the relationship induced by such links is very...

The leucine-rich repeat kinase-2 (LRRK2) gene has been regarded as 1 of the most common genetic causes of Parkinson's disease (PD). We hypothesized that LRRK2-susceptible allele(s) for PD might pose a risk for Alzheimer's disease (AD). In this study, we screened 12 LRRK2 gene variants in 2 independent cohorts from southwestern China (341 AD patients and 435 normal individuals) and eastern China...

Platelet Rich Plasma (PRP) has gained popularity in recent years for treating sports-related injuries and the news media frequently reports on elite athletes' and celebrities' use of PRP. We conducted a content analysis of newspaper coverage of PRP in Australia, Canada, Ireland, New Zealand, United Kingdom, and the United States. Findings show that news media coverage of PRP appears most freque...

This article examines why cognitively oriented technology innovations, designed to foster deep thinking and learning, have not become widespread in K–12 schools. We argue a key reason is that most design-based research does not explicitly address systemic issues of usability, scalability and sustainability. This limitation must be overcome if research is to create usable knowledge that addresse...

We present single-dish Lovell telescope H i observations of a sample of 67 emission-line and UV-excess galaxies, of which 52 are taken from the University of Michigan (UM) catalogue. In addition, H i observations of 24 gas-rich irregular galaxies are presented. We find that emission-line galaxies are H i–rich with a median H i mass to blue luminosity ratio MHI /LB of ∼ 0.45 M /L . Within the UM...
