Background: The relationship between nurse staffing, skill-mix and quality of care has been well-established in medical and surgical settings, however, there is relatively limited evidence of this relationship in emergency departments. Those that have been published identified that lower nurse staffing levels in emergency departments are generally associated with worse outcomes with the conclusion that the evidence in emergency settings was, at best, weak. Methods: We searched thirteen electronic databases for potentially eligible papers published in English up to December 2023. Studies were included if they reported on patient outcomes associated with nurse staffing within emergency departments. Observational, cross-sectional, prospective, …

What Accounts For The Effect Of Sustainability Engagement On Stock Price Crash Risk During The Covid-19 Pandemic—Agency Theory Or Legitimacy Theory?, Junru Zhang, Chen Zheng, Yuan G. Shan

Research outputs 2022 to 2026

In this study, we conduct a textual analysis of the third-party disclosure of corporate sustainability news focused on the Standard and Poor's 500 firms in the United States market during the first and second quarter of 2020. We find a positive relationship between corporate sustainability news release and firm-specific stock price crash risk. This finding is surprising, but it indeed aligns with agency theory. It indicates that the coronavirus disease (COVID-19) pandemic exacerbated the tendency of managers under increasing financial pressure to use the sustainability information release as a mechanism to mask and withhold bad news for extended periods at …

Research outputs 2022 to 2026

Gas extraction from Coal Bed Methane has proved challenging mainly due to the low permeability of coals. This study investigated a combination of 2 stimulation techniques, Liquid Nitrogen (LN2) fracturing and acidizing, to increase pore structure and cleat network connectivity in coals. Microcomputed Tomography ( -CT) scanning results suggested that a combination of those 2 applications, in either sequence of implementation, has substantial potential in recovering mineralized fractures and inducing new fractures; thus, leading to wide-open cleat networks. X-ray images show that if LN2 fracturing of coal is preceded by acidizing, the stimulation efficiency increases from more than double the …

Research outputs 2022 to 2026

The underground storage of CO2 in a depleted carbonate formation is a suitable method for limiting its anthropogenic release and minimize global warming. The rock wettability is an essential factor controlling the mechanisms of CO2 trapping and its containment safety in the geo-storage formation. The geo-storage rock contains innate organic acids which alters the wettability of the rock surface from the hydrophilic condition to the hydrophobic state, thus reduce the CO2 storage capacity. In this study, methyl orange which is a toxic dye that is generally released into environment was used as wettability modifier to change the wettability of stearic …

Usda Wildlife Services Management Efforts At The Grand Forks Wastewater Treatment Plant, Dorothy Celeste Daulton

Theses and Dissertations

Wildlife collisions with aircraft (wildlife strikes) are a costly and dangerous issue. In recent decades, wildlife strikes within airport boundaries have decreased partly due to on-airfield wildlife strike mitigation efforts. Landscape attractants surrounding airfields within an 8 km radius have been found to influence the occurrence of wildlife strikes by increasing wildlife presence and abundance on or near airfields. The effectiveness of mitigation efforts can be increased by extending operations to include landscape features in an 8 km radius from airports. However, not much is known about the long-term effects of wildlife strike mitigation operations when conducted on neighboring properties, …
