Understanding And Confronting Species Uncertainty In Biology And Conservation, Jody Hey, Robin Waples, Michael L. Arnold, Roger K. Butlin, Richard G. Harrison

United States Department of Commerce: Staff Publications

Recent essays on the species problem have emphasized the commonality that many species concepts have with basic evolutionary theory. Although true, such consensus fails to address the nature of the ambiguity that is associated with species-related research. We argue that biologists who endure the species problem can benefit from a synthesis in which individual taxonomic species are used as hypotheses of evolutionary entities. We discuss two sources of species uncertainty: one that is a semantic confusion, and a second that is caused by the inherent uncertainty of evolutionary entities. The former can be dispelled with careful communication, whereas the latter …

Fisheries Research Contract Report No. 6 - Assessment Of The Nutritional Variability Of Lupins As An Aquaculture Feed Ingredient, Brett Glencross, John Curnow, Wayne Hawkins

Fisheries Research Reports

The nutritional value of the kernel meals of three species of lupin (Lupinus albus, L. angustifolius and L. luteus) was compared against each other and a reference ingredient of solvent extracted soybean meal, when fed to rainbow trout (Oncorhynchus mykiss). Each lupin kernel meal was included in test diets at 300 g/kg and also at a greater level, representing 50% of the total protein content in the diet. The digestibility of protein of all lupin kernel meals was better than for the soybean meal. The highest protein digestibility was that from L. luteus kernel meal at 30% inclusion (100%), which …

The Epidemiology Of U.S. Immunization Law: A National Study For The National Immunizations Program, Centers For Disease Control And Prevention: Medicaid Coverage Of Immunizations For Non-Institutionalized Adults, Sara J. Rosenbaum, Alexandra M. Stewart, Marisa A. Cox, Alexis Lee

Health Policy and Management Faculty Publications

As a health policy matter, coverage of immunizations and their administration for all ages at levels recommended by the Advisory Committee on Immunization Practices (ACIP) has grown in importance for several reasons: 1) the growing attention to both manmade and naturally occurring public health threats; 2) recognition of the value of immunization to society; and 3) the relatively high cost of at least certain immunization services in relation to personal income. No population stands to benefit more from immunization coverage than low income persons.

Studies suggest that adult immunization status is particularly low, and that financial barriers play a role, …

Blood Lead Levels During Pregnancy And Pregnancy Outcome In Karachi Women, A Rahman, A Hakeem

Department of Biological & Biomedical Sciences

objective: To evaluate association of blood lead levels with pregnancy outcome in the obstetrics and gynaecology unit.
Methods: Blood lead levels were measured in 73 pregnant women at the time of delivery and assessed its association with pregnancyoutcome.
Results: Mean maternal lead level was 9.91+/-4.44 mg/dL (range 2.28-36.35 mg/dL). Mothers of boys had significantly higher (p=0.013, one-tailed t test) blood lead levels (11.05+/-5.19) when compared to mothers of girls (8.74+/-3.18 mg/dL.
Conclusion: Maternal lead levels at the time of delivery showed no association with gestational age, birth weight, recumbent length, or head circumference.

September 11: Symbolism And Responses To "9/11", M. R. Hopkins, Raymond F. Hopkins

Political Science Faculty Works

Professors Hopkins and Hopkins review the impact of 9/11 as a symbol in American politics. Following the terrorist attacks, "9/11" became a simple reference condensing wide-ranging events and emotions. Various interpretations emerged about what caused "9/11" and enabled the attacks. The authors claim that 9/11 allowed US leaders to pursue certain policy prescriptions that otherwise would have been blocked. Among four possible prescriptions for responding to the attacks, the Bush administration chose a "praetorian" policy of preventive war, with Iraq as its first example. In the authors’ view, by pursuing an expansive but highly militarized response, the US has overlooked …

Large Scale Ocean Circulation From The Grace Ggm01 Geoid, B. D. Tapley, D. Chambers, S. Bettadpur, J. C. Ries

Marine Science Faculty Publications

The GRACE Gravity Model 01 (GGM01), computed from 111 days of GRACE K-band ranging (KBR) data, is differenced from a global mean sea surface (MSS) computed from a decade of satellite altimetry to determine a mean dynamic ocean topography (DOT). As a test of the GGM01 gravity model, large-scale zonal and meridional surface geostrophic currents are computed from the topography and are compared with those derived from a mean hydrographic surface. Reduction in residual RMS between the two by 30–60% (and increased correlation) indicates that the GGM01 geoid represents a dramatic improvement over older geoid models, which were developed from …

School -To -Home Communication In High School: Effects On Task Engagement And Homework Completion, Daniel Mcdonnell

College of Education Theses and Dissertations

This quasi-experimental study examined the effects of consistent school-to-home communication on homework completion, project completion, grades, attendance, student engagement, student behavior, and student attitude toward homework. Three high school English composition teachers reported data from a sample of 121 sophomores, who completed a pre- and post-survey, the Student Survey of Homework Practices. Each teacher taught a control and treatment class in which communication with the home was increased through phone calls home and weekly notes sent home with students. The post-test analyses by group found that students in the treatment group significantly decreased the amount of homework planning they did. …

Some Law And Economics Of Historic Shipwrecks, Paul Hallwood

Economics Working Papers

This paper examines how US and proposed international law relate to the recovery of archaeological data from historic shipwrecks. It argues that US federal admiralty law of salvage gives far less protection to historic submerged sites than do US laws protecting archaeological sites on US federal and Indian lands. The paper offers a simple model in which the net present value of the salvage and archaeological investigation of an historic shipwreck is maximized. It is suggested that salvage law gives insufficient protection to archaeological data, but that UNESCO's Convention on the Protection of the Underwater Cultural Heritage goes too far …

Methods For Estimating Long-Distance Dispersal, Ran Nathan, Gad Perry, James T. Cronin, Allan E. Strand, Michael L. Cain

Faculty Publications

Long-distance dispersal (LDD) includes events in which propagules arrive, but do not necessarily establish, at a site far removed from their origin. Although important in a variety of ecological contexts, the system-specific nature of LDD makes "far removed" difficult to quantify, partly, but not exclusively, because of inherent uncertainty typically involved with the highly stochastic LDD processes. We critically review the main methods employed in studies of dispersal, in order to facilitate the evaluation of their pertinence to specific aspects of LDD research. Using a novel classification framework, we identify six main methodological groups: biogeographical; Eulerian and Lagrangian movement/redistributional; short-term …

Identification Of Three Genomic Haplotypes 5′ To The Human Cd1d Gene And Their Distribution In Four Ethnic Groups, Q. Y. Chen, N. Jackson, A. Vargas, S. Chalew, J. Rao, M. Batzer, M. S. Lan, Y. H. Chang, M. Mokhashi, D. Liu

Faculty Publications

CD1d presents lipid antigen to a conserved population of natural killer (NK) T cells, which participate in host immune defense, tumor cell rejection and suppression of autoimmunity. The levels of human CD1d expression vary significantly between individuals. To understand such variation, we sequenced the region up to 1.7 kb 5′ upstream of the translation start site and partially through exon 2 in 44 white Americans. We also studied two tagged single nucleotide polymorphisms (SNP) in 112 white Americans, 60 African-Americans, 88 Europeans, and 84 Chinese people from the region. Six SNP present in the region (-836C→T, -773C→T, -764C→G, -713A→T, -365A→G …

Aerobic Denitrification Of Pseudomonas Aeruginosa Monitored By Online Nad(P)H Fluorescence, Fan Chen, Qing Xia, Lu-Kwang Ju

Chemical, Biomolecular, and Corrosion Engineering Faculty Research

Continuous cultures of Pseudomonas aeruginosa (ATCC 9027) maintained at different dissolved oxygen concentrations (DO) were studied for the effects of DO on various culture properties, especially aerobic respiration and denitrification. The DO was varied from 0 mg/liter (completely anoxic conditions) to 1.3 mg/liter and measured with optical sensors that could accurately determine very low DO based on oxygen-quenched luminescence. The strain was found to perform aerobic denitrification; while the specific rate decreased with increasing DO, denitrification persisted at approximately 1/8 of the maximum rate (1.7 mmol/g of cells/h) even at relatively high DO (1 to 1.3 mg/liter). In the presence …

Converting Plant Biomass To Fuels And Commodity Chemicals In South Africa: A Third Chapter?, L R. Lynd, H H Von Blottnitz, B Tait, J De Boer, I S. Pretorius, K Rumbold, W H. Van Zyl

Dartmouth Scholarship

There have been two distinct chapters in the history of converting cellulosic biomass to fuels and commodity chemicals in South Africa. The first chapter, fromthe late 1970s to the early 1990s, involved some of the most active research and development efforts of their kind anywhere in the world. Thereafter, during the second chapter, there has been very little activity in the field in South Africa while there has been an unprecedented awakening to the potential of biomass conversion elsewhere. This paper considers the rationale and possible benefits of a potential third chapter based on a revitalized effort on biomass conversion …

An Analysis Of Single Clutch Paternity In The Burrower Bug Sehirus Cinctus Using Microsatellites, Jeremy M. Brown, Aneil F. Agrawal, Edmund D. Brodie

Faculty Publications

Recent studies of the burrower bug, Sehirus cinctus, have examined the genetic basis of parental care. An understanding of the burrower bug mating system, and the subsequent pattern of offspring relatedness that this system generates, is critical to further interpret genetic data. To this end, we developed three consistently amplifiable highly polymorphic microsatellite loci and used them to determine genotypic patterns at the level of both the population and the single clutch. We found that all clutches were sired by single males. Further, we find no evidence for inbreeding. We hypothesize that single paternity within a clutch may play an …

Pelvic Sexual Dimorphism In A Metatherian, Didelphis Virginiana: Implications For Eutherians, Robert G. Tague

Faculty Publications

Eutherians give birth to relatively large infants. Females have larger pelves than males, though males typically have larger nonpelvic bones. Pelvic dimorphism is an adaptation for parturition. Metatherian females, who give birth to markedly small infants, should not show pelvic adaptations for parturition and should have smaller pelves than males. Adult females and males of the Virginia opossum, Didelphis virginiana, are compared. Males are significantly larger than females in absolute size for 14 of 16 pelvic and 8 nonpelvic measures. Sexes did not differ significantly for lower iliac length and posterior space of midplane. However, relative lengths for females are …

Similar Gene Structure Of Two Sox9a Genes And Their Expression Patterns During Gonadal Differentiation In A Teleost Fish, Rice Field Eel (Monopterus Albus), Rongjia Zhou, Li Liu, Yiqing Guo, Hongshi Yu, Hanhua Cheng, Xiao Huang, Terrence R. Tiersch, Philippe Berta

Faculty Publications

The Sox9 gene encodes a transcription factor that is critical for testis determination and chondrogenesis in vertebrates. Mutations in human SOX9 cause campomelic dysplasia, a dominant skeletal dysmorphology syndrome often associated with male to female sex reversal. Here we show that the Sox9a gene was duplicated during evolution of the rice field eel, Monopterus albus, a freshwater fish which undergoes natural sex reversal from female to male during its life, and has a haploid genome size (0.6-0.8 pg) that is among the smallest of the vertebrates. The duplicated copies of the gene (named Sox9a1 and Sox9a2) fit within the Sox9 …

Building An Environmental Ethic From The Ground Up, Alyson C. Flournoy

UF Law Faculty Publications

Over the last twenty years there has been a remarkable theoretical flourishing in the field of environmental philosophy, with the development of biocentric ethics, animal rights theories, deep ecology, ecofeminism, modified utilitarianism, moral pluralism and theories drawing on numerous religious and cultural traditions. These theories explore the intellectual and moral causes for the environmentally destructive practices of the dominant western industrial and economic culture, and propose alternatives that might avoid these consequences. This symposium raises a worthy question: to what extent have these theories had practical impact on environmental law and policy. I come to this question as a lawyer …

Who Can Defend A Federal Regulation? The Ninth Circuit Misapplied Rule 24 By Denying Intervention Of Right In Kootenai Tribe Of Idaho V. Veneman, Stephanie D. Matheny

Washington Law Review

In Kootenai Tribe of Idaho v. Veneman, the United States Court of Appeals for the Ninth Circuit misapplied Rule 24 of the Federal Rules of Civil Procedure by denying intervention of right to organizations that had protectable interests in the adoption and implementation of the Roadless Rule. The court based its decision to deny intervention of right on its federal defendant rule, which bars intervention of right by parties other than the federal government to defend a challenge brought under the National Environmental Policy Act (NEPA). The Kootenai decision extended the reach of the federal defendant rule to include …

Wing Shape In House Finches Differs Relative To Migratory Habit In Eastern And Western North America, Jeremy R. Egbert, James R. Belthoff

Biology Faculty Publications and Presentations

We investigated whether wing morphology differed between the sedentary House Finches (Carpodacus mexicanus) of western North America and the introduced population of eastern North America, as the latter has developed migratory behavior since its inception. Wing morphology differed between eastern and western House Finches. Eastern House Finches had shorter proximal primaries and a longer outer primary, perhaps reflecting a thinner and more pointed wing, although no disparity in wing length was detected. Since we interpret these differences in wing shape as modifications for flight capability, we believe that initial evidence for morphological divergence relative to migratory habit between eastern and …

Technology, Commentary And The Admonitions For Women, Sherin Wing

Journal of International Women's Studies

The following is an analysis of the Admonitions for Women (Nu Jie) by the Later Han Dynasty scholar, Ban Zhao. It examines the historical context for its composition, applying not only one literary template, that of the instructional text, the technological treatise, but also Confucian Commentary. Through this process, the Admonitions emerges as a sophisticated philosophical tract that combines not only several literary traditions, but applies them to a new, unique audience: elite women. In so doing, Ban Zhao challenges assumptions of women’s roles, expectations of women, and enlightens her readers as to what might be really happening …
