A variety of criteria may influence the efficacy of networks of marine protected areas (MPA) designed to enhance biodiversity conservation and provide fisheries benefits. Meta-analyses have evaluated the influence of MPA attributes on abundance, biomass, and size structure of harvested species, reporting that MPA size, age, depth, and connectivity influence the strength of MPA responses. However, few empirical MPA evaluation studies have used consistent sampling methodology across multiple MPAs and years. Our collaborative fisheries research program systematically sampled 12 no-take or highly protective limited-take MPAs and paired fished reference areas across a network spanning 1100 km of coastline to evaluate …

Faculty Publications

Impacts are critical to producing the aqueous environments necessary to stimulate prebiotic chemistry on Titan’s surface. Furthermore, organic hazes resting on the surface are a likely feedstock of biomolecules. In this work, we conduct impact experiments on laboratory-produced organic haze particles and haze/sand mixtures and analyze these samples for life’s building blocks. Samples of unshocked haze and sand particles are also analyzed to determine the change in biomolecule concentrations and distributions from shocking. Across all samples, we detect seven nucleobases, nine proteinogenic amino acids, and five other biomolecules (e.g., urea) using a blank subtraction procedure to eliminate signals due to …

The Metameric Echinoderm, Richard L. Turner Mar 2024

The Metameric Echinoderm, Richard L. Turner

Ocean Engineering and Marine Sciences Faculty Publications

Animal phyla are distinguished by their body plans, the ways in which their bodies are organized. A distinction is made, for example, among phyla with bodies of many segments (metameric; e.g., annelids, arthropods, and chordates), others with completely unsegmented bodies (americ; e.g., flatworms and mollusks), and a few phyla with bodies of 2 or 3 regions (oligomeric; e.g., echinoderms and hemichordates). The conventional view of echinoderms as oligomeric coelomates adequately considers early development, but it fails to recognize the metameric body plan that develops in the juvenile rudiment and progresses during indeterminate adult growth. As in the 3 phyla traditionally …

Role Of Sfgsi, Microbial Culture And Qsofa As Predictive Factors In Determining The Survival Rate In Fournier Gangrene Patient, Syah M. Warli, Karimul A. Pakpahan, Ramlan Nasution, Dhirajaya D. Kadar, Kharisma P. Adhyatma

Saudi Medical Journal

Objectives: To examine the simplified Fournier Gangrene Severe Index Score (SFGSI) and the number of species in culture findings for predicting death in Fournier Gangrene (FG) patients in terms of their predictive power. Methods: From January 2017 to July 2022, the medical records of individuals undergoing emergency surgery for FG were obtained. A total of 80 patients were examined for clinical data such as age, gender, laboratory parameters, etiology, isolated bacteria, and mortality rate. Results: We identified a statistically significant mean difference between SFGSI ( p <0.0001) and quickSOFA (qSOFA) scores ( p =0.002) in determining the survival rate of FG patients. The sensitivity and specificity of the SFGSI score in predicting mortality were 90.1% and 88.3% respectively, whereas the sensitivity and specificity of the qSOFA score were 88.2% and 86.2%. E. Coli comprised 56.2% of the bacteria, followed by S. Haemolyticus , S. Aureus , P. Aeruginosa , and K. Pneumoniae . On the basis of bacterial culture results, P. Aeruginosa had the highest fatality rate (100%) followed by S. Aureus (75%), S. Haemolyticus (30%), and E. Coli (20%), in that order. Conclusion: The survival rate of FG patients can be predicted using the sensitivity and specificity of the SFGSI and qSOFA scores together. P. Aeruginosa- infected patients have the greatest mortality rate (100%) compared to the other groups.

Not Such Massively Discretionary Trusts: Proper Purposes Doctrine And Protectors As Means Of Control, Man Yip, Hang Wu Tang Mar 2024

Not Such Massively Discretionary Trusts: Proper Purposes Doctrine And Protectors As Means Of Control, Man Yip, Hang Wu Tang

Research Collection Yong Pung How School Of Law

Innovation in drafting trust deeds has been central to international trust practice resulting in the discretionary trusts being the norm in modern wealth management. In a seminal article, Lionel Smith observes that these trust drafting practices have ‘led to an increase in the dispositive discretions held by trustees’. His analysis deprecates this development where the ‘trustees’ dispositive discretions effectively govern the whole trust structure’—which he labels ‘massively discretionary trusts’. Smith goes on to detail the various legal risks entailed in massively discretionary trusts which generally arise from the fact that the explicitly identified residuary or default beneficiaries are usually not …

Within-Development Density And Housing Prices In Singapore, Eric Fesselmeyer, Haoming Liu, Louisa Poco Mar 2024

Within-Development Density And Housing Prices In Singapore, Eric Fesselmeyer, Haoming Liu, Louisa Poco

Research Collection College of Integrative Studies

This paper measures how much more households pay for less density in their immediate surroundings. Using transaction and administrative data and exploiting the introduction of a regulation that restricted the number of housing units for certain land lots, we find that households discount density: a 10% increase in within-development density decreases the price per square meter by 5%. Further, the mean price per square meter of the average development increased by 1%–3% after the regulation was introduced, while the amount of built-up space remained constant. The increase in total revenue suggests developers may underestimate the externality caused by density.
