Leaching Properties of Estuarine Harbor Sediment Before and After Electrodialytic Remediation

Electrodialytic remediation (EDR) can be used to extract heavy metals from a variety of different media. In this work, contaminated harbor sediments from two locations in the United States and one in Norway were subjected to EDR, and were compared with batch extractions conducted with the sediment. pH-dependent leaching tests were used to evaluate changes in leaching properties of treated and control sediments. Significant fractions of total concentrations were removed during treatment (35–95% with an average of 75% for all sediments and elements investigated). The release of elements in pH-dependent leaching tests, however, demonstrated equal or greater leaching from treated sediments in the neutral pH range. Dissolved organic carbon appears to be a significant contributor to post-treatment increases in leaching, and dissolution of significant iron and aluminum sorption sites is hypothesized to also play a role. This research highlights the importance of understanding contaminant speciation and availability, as total metals concentrations, in this particular case, do not relate to estimates of the environmental availability of metals (total concentrations were typically two to three orders of magnitude greater than concentrations released during pH-dependent leaching)

Sex Torts

America has a serious sexual problem. The sexual practices of a small percentage of Americans has created an unprecedented disease rate that is costing the American public about $20 billion per year. Lawsuits seeking damages for sexual disease transmission are on the rise, yet current sex tort law is mired with anti-heartbalm sentiment, is unpredictable, and is failing as a tool of deterrence, compensation, and education. This Article discusses the gravity of the sexual disease crisis, part of which is the public’s incredible ignorance about the rate of sexual disease, and tort law’s failure to do its part to help educate the public and deter irresponsible sexual behavior. This Article concludes that, based on the high degree of risk involved in irresponsible sex, and the problems created by the current negligence-based analytical paradigm, strict liability for sexual disease transmission should be adopted. Strict liability would deter sexual disease transmission, and educate the public about the sexual disease epidemic, more effectively than negligence

Unconscious Bias and Self-Critical Analysis: The Case for a Qualified Evidentiary Equal Employment Opportunity Privilege

Recent breakthroughs in social psychology have resulted in the ability to measure unconscious bias scientifically. Studies indicate that prejudiced responses are largely unconscious, the result of normal cognitive processing and stereotypical associations of which the prejudiced subject may be completely unaware. The studies also indicate that a subject\u27s awareness of the discrepancy between her conscious, egalitarian value system and her unconscious prejudice is a critical step towards the convergence of her cognitive functioning and her egalitarian viewpoints. Antidiscrimination legislation requires a showing of intent to discriminate to obtain relief in all but a small percent of circumstances. The result is a legal framework that does not, and cannot, properly redress most instances of discrimination. While the use of unconscious-bias testing may be more effective than antidiscrimination legislation in identifying and redressing the cognitive phenomenon of discrimination, evidence law does not support its use because test results are not privileged against discovery in discrimination lawsuits. This Article argues that in light of the enormous potential social benefit of unconscious-bias testing, a qualified evidentiary privilege should be recognized to encourage its use

Evolution of a transdisciplinary "One Medicine-One Health" approach to global health education at the University of California, Davis.

In today's world health events in one nation or geographic area often have repercussions for the health and well-being of populations beyond that region; sometimes even globally. In recent years many factors, most notably concern about emerging infectious diseases, have contributed to an increasing appreciation of the interdependency of human, animal and ecosystem health worldwide. Integrated global approaches to improve the health of humans, animals and their shared environments are proving to be in the best interest of many countries. A special symposium and award were established in memoriam to the internationally renowned epidemiologist, Dr. Calvin W. Schwabe, who (while at the University of California, Davis) was a significant advocate of the "One Medicine" approach to public health, calling upon all health professionals, including veterinarians, to work collaboratively and comparatively to improve human health. This paper discusses the evolution of the "One Medicine" concept into a global "One Health" approach to research, training capacity and service infrastructure, focused not only on disease, but also on health at the individual, population, and ecosystem levels. Projects involving UCD faculty which attempt to integrate a One Health approach include the Health for Animals and Livelihood Improvement (HALI) Project in Tanzania, Envirovet Summer Institute, Avian Flu School and Newcastle Immunization Program in Africa, a web-based virtual global health training program, and the Calvin Schwabe One Health Project

Conversations With Long-Time Adult Educators

The purpose of this study was to collect and analyze information from long-time adult educators, to learn from their experiences, and to ensure the wisdom they have gained throughout their time spent in the field is not lost

The Utilization of Noni Leaf Silage (Morinda Citrifolia L.) with Marine Yeast Inoculant in Feed to Growth of Kissing Gouramy (Osphronemus Gouramy Lac.)

This research aims to determine the effect of noni leaf silage on food efficiency and growth of kissing gouramy (Osphronemus gouramy Lac.) using the experimental method, completelly randomized design with one factor, five treatments and three replication which had different level comparison of soy bean meal and noni leaf silaged meal, spesifically P1 (100%TK : 0%TSDM), P2 (90% TK : 10%TSDM), P3 (80% TK : 20%TSDM), P4 (70% TK : 30%TSDM), dan P5 (60% TK : 40%TSDM). The result indicated that feed with addition noni leaf silage meal on 10, 20, 30, and 40% were significant effect (P<0.05) on feed effiency, and very significant effect (P<0,01) on protein retention and average specific growth. The best treatments is obtained on P5 addition noni leaf silage as much as 40% with average feed efficiency of 26.57%, protein retention of 25.27%, spesific growth rate 2.32%/day, feed digestived of 72,83% and survival rate of 97%

Research on Cognitive Domain in Geoscience Learning: Quantitative Reasoning, Problem Solving, and Use of Models

Models (from simple mental models to complex computational models) are used by geoscientists to conceptualize and better understand the Earth system and to make predictions. Earth processes affect the human condition and result in hazards and complex issues that require both expert and citizenry decision-making about mitigation and adaptation. In addition, a wide range of Earth materials (e.g., mineral, rock, water) are valued resources that need sustainable management. All of these challenges require recognition of the problem (problem-finding), and the development and application of problem-solving skills. In addition, Earth system understanding and problem-solving benefit strongly from quantitative reasoning. Quantitative reasoning, problem-solving, and use of models present many daunting challenges to both students and instructors. All are valued by the professional geoscience community and by employers, and all would benefit from more education research. In this chapter, grand challenges and recommended strategies for each of these areas are identified and described
