Effectiveness of the CDC HEADS UP online training on healthcare providers’ mTBI knowledge and self-efficacy

Background: Many healthcare providers do not consistently implement recommendations contained in clinical guidelines on mild traumatic brain injury (mTBI). As such, the Centers for Disease Control and Prevention (CDC) created the HEADS UP to Healthcare Providers online training to promote uptake of five key recommendations in the CDC Pediatric mTBI Guideline. Methods: Using data from modules in the CDC HEADS UP to Healthcare Providers online training, healthcare providers’ self-reported knowledge and self-efficacy prior to and immediately following completion of the training was analyzed. Results: Improvements for 8 out of the 10 knowledge questions had a high level of practical significance. The knowledge question with the highest level of practical significance pre- to post-test improvement was for the key guideline recommendation on neuroimaging (pre-test correct: 70.2%; post-test correct: 87.8%; (p < 0.0001, Cohen’s g = 0.39). Four out of the six questions had a self-efficacy level increase of a high level of practical significance (r > 0.50) between the pre- and post-tests. The self-efficacy question with pre- to post-test improvement with the highest level of practical significance was “I am confident in my ability to manage the return to sports progression for my patients” (p < 0.001; r = 0.54). Conclusions: The HEADS UP to Healthcare Providers online training led to significant improvements in knowledge and self-efficacy related to mTBI diagnosis and management. Expanded use of this training among healthcare providers who commonly provide care for pediatric patients with mTBI may be beneficial. Practical Applications: This study highlights several factors guideline developers may take into consideration when creating an implementation tool, such as using health behavior theories, working with partners and key stakeholders, and focusing on digital-based tools.

On the implementation of an International Curriculum on Hydrogen Safety Engineering into higher education

This paper describes the implementation of an International Curriculum on Hydrogen Safety Engineering into higher education. The curriculum is being developed as part of the educational and training activities of the European Network of Excellence Safety of Hydrogen as an Energy Carrier (HySafe) and has been implemented into a 1-year Postgraduate Certificate Course in Hydrogen Safety Engineering by the University of Ulster. The course is taught in the distance learning mode and comprises of two 30 CATS-point modules, namely, ‘Principles of Hydrogen Safety’ and ‘Applied Hydrogen Safety’. The first delivery of this course began in January 2007 and the second delivery will commence in September 2007.

Investigation the effect of adding graphene oxide into diesel/higher alcohols blends on a diesel engine performance

ABSTRACT

This article aims to study the influence of the addition of graphene oxide nanoparticles (GO) to diesel/higher alcohols blends on the combustion, emission, and exergy parameters of a CI engine under various engine loads. The higher alcohols mainly n-butanol, n-heptanol, and n-octanol are blended with diesel at a volume fraction of 50%. Then, the 25 and 50 mg/L concentrations of GO are dispersed into diesel/higher alcohols blends using an ultrasonicator. The GO structures are examined using TEM, TGA, XRD and FTIR. The findings show that there is a reduction in p_max. and HRR when adding higher alcohols with diesel fuel. Regarding engine emission, there is a significant improvement in emissions formation with adding higher alcohols. The addition of GO into diesel/higher alcohols blends improves the brake thermal efficiency by 15%. Moreover, the p_max. and HRR are both enhanced by 4%. The CO, UHC and smoke formation are reduced considerably by 40%, 50 and 20%, respectively, while NO_x level is increased by 30% with adding GO. Finally, adding high percentages of n-butanol, n-heptanol, and n-octanol with diesel fuel with the presence of GO has the potential to achieve ultra-low CO, UHC, and smoke formation meanwhile keeping high thermal efficiency level.     

Environmental impacts of iron ore tailings—The case of Tolo Harbour,Hong Kong

Disposal of iron ore tailings along the shore of Tolo Harbour, Hong Kong has altered the adjacent environment. Due to the ever-expanding population, the vast development of various industries, and the lack of sanitary control, the existing pollution problem of Tolo Harbour is serious. The iron ore tailings consist of a moderate amount of various heavy metals, e.g., copper, iron, manganese, lead, zinc, and a lower level of macronutrients. A few living organisms have been found colonizing this manmade habitat. Higher metal contents were also found in the tissue ofPaphia sp. (clam);Scopimera intermedia (crab);Chaetomorpha brychagona (green alga);Enteromorpha crinita (green alga); andNeyraudia reynaudiana (grass). The area can be reclaimed by surface amelioration using inert materials, soils, or organic substrates, and by direct seeding, using nontolerant and tolerant plant materials. Reclamation of the tailings would improve the amenity of the adjacent environment and also mitigate pollution escaping to the sea.     

Displaced in Nature: The Cultural Production of (Non-)Place in Place-Based Forest Conservation Pedagogy

This study examines spatial practices in a forest conservation education program that incorporates place as a tool to teach environmental and forestry issues to schoolchildren and connect them with nature. By analyzing educational forests, “talking-tree trails,” classes taught to children, and how visitors move throughout the sites, this paper argues that people and practices within the forests employ a rhetoric of spatial and temporal transience that can enable a displaced experience. Human-nature dualistic tendencies that foster environmental alienation are produced culturally and spatially and are experienced in ways that can promote disconnectedness. Instead of re-placing students with nature, as place-based environmental education promotes, forestry and pedagogical systems can practice nature as non-placed.
