Hydrostatic force used to handle outsized, heavy objects

Specially fitted barge is used to load and transport large, heavy objects to a dock side site. There the barge itself can lift, rotate, and position the objects. Typical functions are economically accomplished by water buoyancy

Does Familiarity breed inattention? Why drivers crash on the roads they know best

This paper describes our research into the nature of everyday driving, with a particular emphasis on the processes that govern driver behaviour in familiar, well - practiced situations. The research examined the development and maintenance of proceduralised driving habits in a high-fidelity driving simulator by paying 29 participants to drive a simulated road regularly over three months of testing. A range of measures, including detection task performance and driving performance were collected over the course of 20 sessions. Performance from a yoked control group who experienced the same road scenarios in a single session was also measured. The data showed the development of stereotyped driving patterns and changes in what drivers noticed, indicative of in attentional blindness and “driving without awareness”. Extended practice also resulted in increased sensitivity for detecting changes to foveal road features associated with vehicle guidance and performance on an embedded vehicle detection task (detection of a specific vehicle type). The changes in attentional focus and driving performance resulting from extended practice help explain why drivers are at increased risk of crashing on roads they know well. Identifying the features of familiar roads that attract driver attention, even when they are driving without awareness, can inform new interventions and designs for safer roads. The data also provide new light on a range of previous driver behaviour research including a “Tandem Model” that includes both explicit and implicit processes involved in driving performance

Persisting mobile phone use while driving and possible solutions for New Zealand

In New Zealand the use of hand-held phones while driving was prohibited in 2009, but ‘hands-free’ phones are still permitted. We recently presented the results of an observational study into mobile phone among Wellington drivers at a conference (for details see the proceedings). The main findings were that out of 8335 cars systematically observed at traffic lights and 9520 cars in moving traffic (each at three different Wellington locations), the use of mobile phones was 1.87% (95%CI: 1.60-2.18) and 1.34% (95%CI: 1.13-1.59) respectively

Radio, the Resilient Medium Papers from the Third Conference of the ECREA Radio Research Section

Radio is a resilient medium. It has evolved considerably over its hundred-year history and we have every reason to believe that evolution will continue. This book is a peer- reviewed collection of papers from the third conference of the Radio Research Section of the European Research and Education Association (ECREA), held at the London Campus of the University of Sunderland in September 2013. It represents some of the best research presented at the conference, but every chapter has been revised and edited prior to publication. The book, like the conference, is an initiative of the Centre for Research in Media and Cultural Studies (CRMCS), which is based in Sunderland. Published by the Centre for Research in Media and Cultural Studies, University of Sunderland, Sunderland, United Kingdom SR1 3SD

Examining Suicidal Thoughts and Behaviors Among Ohio Youth with Oppressed Identities Using the 2019 Ohio Youth Risk Behavior Survey

Background: Suicide is the second leading cause of death among youth aged 10 to 14 years and third for those aged 15 to 24 years in the United States and in Ohio. Suicidal thoughts and behaviors disparately affect youth with oppressed identities, including those with oppressed racial, ethnic, gender, and sexual minority identities. The purpose of this study was to examine the relationship between self-reports of suicidal thoughts and behaviors among Ohio youth with oppressed identities. This research also contextualizes relationships between these indicators through the context of intersectionality. Methods: This cross-sectional descriptive study used responses from the 2019 Ohio Youth Risk Behavior Survey (YRBS; n = 1263) to examine the relationships between identity variables and suicidal thoughts and behaviors through a series of logistic regression models. Results: Female youth have higher odds of reporting persistent feelings of sadness and hopelessness and seriously considering suicide than male youth. Lesbian, gay, or bisexual (LGB) youth have higher odds of reporting all outcome measures of suicidal thoughts and behaviors (STBs), and youth with oppressed racial and ethnic identities were in general more likely to report higher odds of STBs when compared to White youth. Conclusion: Suicidal thoughts and behaviors disparately affect youth with these oppressed identities. Our findings suggest further examination of these youth nationally may influence public health suicide prevention strategies. Implica-tions also suggest that researchers, practitioners, and organizations across the spectrum of youth suicide prevention in Ohio should understand the increased risk that youth with multiple, intersectional oppressed identities face for suicide

Magnetization transfer contrast MRI in GFP-tagged live bacteria

Green fluorescent protein (GFP) is a widely utilized molecular reporter of gene expression. However, its use in in vivo imaging has been restricted to transparent tissue mainly due to the tissue penetrance limitation of optical imaging. Magnetization transfer contrast (MTC) is a magnetic resonance imaging (MRI) methodology currently utilized to detect macromolecule changes such as decrease in myelin and increase in collagen content. MTC MRI imaging was performed to detect GFP in both in vitro cells and in an in vivo mouse model to determine if MTC imaging could be used to detect infection from Pseudomonas aeruginosa in murine tissues. It was demonstrated that the approach produces values that are protein specific and concentration dependent. This method provides a valuable, non-invasive imaging tool to study the impact of novel antibacterial therapeutics on bacterial proliferation and perhaps viability within the host system, and could potentially suggest the modulation of bacterial gene expression within the host when exposed to such compounds
