Cost Of Salvage?€“ A Comparative Form Approach, Chung-Sheng Chiu, Chung-Ping Liu, Ki-Yin Chang, Wen-Jui Tseng, Yung-Wei Chen

Journal of Marine Science and Technology–Taiwan

The most important principle of salvage is the "No Cure-No Pay" basis, if there is no recovery, there is no payment, whatever the expense of the operation. However, this principle has changed in recent years to reflect the public interest in prevention of damage to the environment (Mudric, 2010). The salvor can now contract in such a way that he is shielded from loss when responding to high risk or low value casualties (so called as "No Cure-Some pay"). Salvage is a high-profit business and high-risk as well in the world. The case of the Costa Concordia - by no …

Researchers have looked to user factors for explanations of this gap, finding security and convenience to be common considerations, along with perceptions of risks and past experiences. Some have tried to alter user behavior, but are targeted at specific advice and focused on rational motivations to persuade users.

In this thesis, three expertly recommended cybersecurity advice (i.e., updating software regularly, using two-factor authentication, using a secure password manager) are deeply explored. These results inform the design of videos in a systematic study …

Modeling Iron Oxide Reactivity In The Environment, Nefeli Maria Bompoti

Doctoral Dissertations

Iron oxides and hydroxides are highly reactive mineral phases in natural systems since they interact with pollutants, controlling their fate and transport in the environment. Goethite (GH) and hematite (HT) are the most abundant iron minerals in nature, while ferrihydrite (FH) is a nanomineral with high surface reactivity. Subsurface transport modeling has usually represented the adsorption processes by empirical relationships, such as distribution coefficients (K_d) or isotherm equations. However, empirical approaches cannot account for variable geochemical conditions. These effects can be addressed by the mechanistic surface complexation models (SCMs). So far, the application of SCMs has been limited …

Improving Early Sepsis Identification On Inpatient Units, Hannah Pari

Master's Projects and Capstones

Sepsis is a life threatening medical emergency that if left untreated could ultimately lead to death. It is defined as the body’s extreme response to infection which can rapidly worsen if not identified and managed quickly. As sepsis worsens, it leads to extended hospital stays, poor patient prognoses and increased hospital costs. In an effort to combat these negative outcomes, efficient protocols must be implemented hospital wide. A 5 P’s microsystem assessment was preformed to assess the purpose, patients, professionals, processes and patterns. Additionally, assessments were conducted to collect baseline nursing knowledge regarding sepsis criteria, treatment, and hospital protocol. A …

Development Of A Formalized Mentorship Program, Rozlyn Bauer

Master's Projects and Capstones

The purpose of this project is to help increase retention of newly licensed registered nurses (NLRN) at a large community medical center. The medical center loses approximately 20 NLRNs per year which is costly for the medical center. The loss of NLRN can be attributed to decreased job satisfaction, poor nursing competence and lateral violence between the nursing staff. Evidence shows that mentorship is a proven, evidence-based approach to solving these issues and more (Hodgson & Scanlan, 2013).

Not only can mentorship help increase retention, address lateral violence, increase job satisfaction and nursing competence but, it can also help enhance …
