Artificial Reef Matrix Structures (Arms): An Inexpensive And Effective Method For Collecting Coral Reef-Associated Invertebrates, Todd L. Zimmerman, Joel W. Martin

Gulf and Caribbean Research

Collecting reef-associated invertebrates usually involves disturbance of the reef area, often damaging the habitat and sometimes damaging live corals. We introduce a nondestructive, inexpensive, and effective method for collecting coral reef-associated invertebrates using approximations of small coral heads constructed of concrete, PVC pipes, nylon cleaning pads, and other materials easily obtainable in most tropical (coral-rich) countries. An example showing the effectiveness of the method is presented based on fieldwork in the eastern Caribbean.

Helminths From Dormitator Maculatus (Pisces: Eleotridae) In Alvarado Lagoon, Veracruz, Mexico, And Supplemental Data For Clinostomum Complanatum Rudolphi, 1814 From Egretta Caerulea (Aves: Ardeidae), Jesus Montoya-Mendoza, Rafael Chavez-Lopez, Jonathan Franco-Lopez

Gulf and Caribbean Research

Fishes are important hosts of helminths with aquatic life stages, yet little information is available on host-parasite relationships in tropical low salinity ecosystems. In this paper we report helminth parasites of the fat sleeper, Dormitator maculatus, in the Alvarado lagoon system, Veracruz. Mexico. Four parasite species were recorded from D. maculatus, including trematode metacercariae of Clinostomum complanatum, as well as nematode larvae of Spyroxis sp. and Camallanus sp. and adults of Neochinorhynchus golvani. In addition, we obtained adult C. complanatum from the esophagus of the little blue heron, Egretta caerulea. Dormitator maculatus is a new …

Anatomy Of A Chaotic Attractor: Subtle Model-Predicted Patterns Revealed In Population Data, Aaron A. King, R. F. Costantino, J. M. Cushing, Shandelle M. Henson, Robert A. Desharnais, Brian Dennis

Faculty Publications

Mathematically, chaotic dynamics are not devoid of order but display episodes of near-cyclic temporal patterns. This is illustrated, in interesting ways, in the case of chaotic biological populations. Despite the individual nature of organisms and the noisy nature of biological time series, subtle temporal patterns have been detected. By using data drawn from chaotic insect populations, we show quantitatively that chaos manifests itself as a tapestry of identifiable and predictable patterns woven together by stochasticity. We show too that the mixture of patterns an experimentalist can expect to see depends on the scale of the system under study.

Age-Related Differences In Susceptibility To Carcinogenesis: A Quantitative Analysis Of Empirical Animal Bioassay Data, Dale Hattis, Robert Goble, Abel Russ, Margaret Chu, Jen Ericson

Sustainability and Social Justice

In revising cancer risk assessment guidelines, the U.S. Environmental Protection Agency (EPA) analyzed animal cancer bioassay data over different periods of life. In this article, we report an improved analysis of these data (supplemented with some chemical carcinogenesis observations not included in the U.S. EPA's original analysis) and animal bioassay studies of ionizing radiation. We use likelihood methods to avoid excluding cases where no tumors were observed in specific groups. We express dosage for animals of different weights on a metabolically consistent basis (concentration in air or food, or per unit body weight to the three-quarters power). Finally, we use …

Intellectual Property Law And Indigenous Peoples: Adapting Copyright Law To The Needs Of A Global Community, Megan M. Carpenter

Faculty Scholarship

The definition and scope of intellectual property and associated laws are under intense debate in the emerging discourse surrounding intellectual property and human rights. These debates primarily arise within the context of indigenous peoples' rights to protection and ownership of culturally specific properties. It is true that intellectual property laws are based on Western, developed markets, Western concepts of creation and invention, and Western concepts of ownership. But whatever their origins, those laws have been, and currently are, the primary vehicle for the protection of artistic, literary, and scientific works worldwide. To segregate indigenous interests from this international legal regime, …

The Private Foundation's Topsy Turvy Road In The American Political Process, William H. Byrnes Iv

Faculty Scholarship

This article studies this American political debate on the charitable tax exemption from 1864 to 1969, in particular, the debate regarding philanthropic, private foundations. The article's premise is that the debate's core has little evolved since that between the 1850s and 1870s. To create perspective, a short brief of the modern economic significance of the foundation sector follows. Thereafter, the article begins with a review of the preand post-colonial attitudes toward charitable institutions leading up to the 1800s debates, illustrating the incongruity of American policy regarding whether and to what extent to grant charities tax exemption. The 1800s state debates …

[N]Ot A Story To Pass On: Constructing Mothers Who Kill, Susan Ayres

Faculty Scholarship

Toni Morrison has said in her Nobel acceptance speech, “We die. That may be the meaning of life. But we do language. That may be the measure of our lives.” How we “do language” in judicial decisions about infanticide can perhaps be compared to and informed by fiction such as Toni Morrison’s Beloved.

Beloved provides a fictional account of the life of a historical woman, a slave who escaped to freedom and then attempted to kill all four of her children, successfully killing one when her master came to claim her under the Fugitive Slave Act. In addition to …

The Effects Of A One-Tesla Magnet On Human Fibroblast Cell Growth, Ashley Chaplin

Theses and Dissertations

The controversy regarding the ill effects of electromagnetic fields began in 1979 when Nancy Wertheimer and Ed Leeper claimed to have found a connection between childhood leukemia and power lines. In 1997, a group of researchers led by Martha Linet, M. D., attempted to provide evidence that there was no link between cancer and electromagnetic fields. The study showed that the risk of acute lymphoblastic leukemia did not escalate with increasing electromagnetic field levels in the children's homes. When compared to the Earth's static magnetic field of 0.5 Gauss, these fields were extremely small. Within the past decade, magnets have …

Communitarianism And Republicanism, Richard Dagger

Political Science Faculty Publications

Communitarianism and republicanism are closely related schools of thought - so closely related that friend and foe alike sometimes conflate them. The relationship is evident in their Latin roots: communitarians are concerned with communitas, the common life of people who form a community, and republicans are devoted to the res publica, the good of the public. Of the two, however, only republicanism traces its lineage as well as its name to ancient Rome. Indeed, scholars often look beyond Rome to the philosophers and city-states of ancient Greece, particularly Aristotle and Sparta, for the origins of republicanism. For the …

Revisioning The Oversight Of Research Involving Humans In Canada, Jocelyn Downie, Fiona Mcdonald

Articles, Book Chapters, & Popular Press

When individuals are asked to participate in research they should be able to assume that the research "is well designed and well executed, that the investigator is competent to undertake the study, that the study will be run efficiently, safely, and ethically and that the deviations from good practice will be identified and corrected." The central question that we focus on in this paper is whether the governance mechanisms that are currently in place to regulate the conduct of research involving humans are adequate to enable those who are approached to participate in research to make these assumptions. This review …

Climate Change And The Wto: Opportunities To Motivate State Action On Climate Change Through The World Trade Organization, Meinhard Doelle

Articles, Book Chapters, & Popular Press

This article explores the role of trade in motivating action on climate change, using the specific example of developments within the World Trade Organization (WTO).

The Kyoto Protocol, the first international agreement with legally binding commitments to begin to address climate change by reducing greenhouse gas (GHG) emissions, is expected to come into force in 2004. With it, most of the developed world will be committed to modest reduction targets over the next decade. The two largest per capita emitters, the USA and Australia, have so far opted not to join this modest effort to address climate change, and developing …

So Much Activity, So Little Change: A Reply To The Critics Of Battered Women's Self-Defense, Kit Kinports

Faculty Scholarship

Prior to 1970, the term "domestic violence" referred to ghetto riots and urban terrorism, not the abuse of women by their intimate partners. Today, of course, domestic violence is a household word. After all, it has now been ten years since the revelation of football star O.J. Simpson's history of battering purportedly sounded "a wake-up call for all of America"; ten years since Congress enacted legislation haled as "a milestone . . .truly a turning point in the national effort to break the cycle" of violence; and twenty years since Farrah Fawcett's portrayal of Francine Hughes in the movie The …

Benumbed, Carl E. Schneider

Articles

I originally intended to write a column on tort liability and research ethics, and I still plan to do so. But this column is a cri de coeur as I finish another semester teaching law and bioethics. This year, I asked with growing frequency, urgency, and exasperation, "Must law's reverence for autonomy squeeze out the impulse to kindness? Where is the beneficence in bioethics?" These questions assail me every term. Why? Consider Steele v. Hamilton County Community Mental Health Board. Mr. Steele was involuntarily "hospitalized after his family reported that he was 'seeing things and trying to fight imaginary …

Cognitive Impact Of Interactive Multimedia, Yanko F. Michea,

Dissertations and Theses (Open Access)

Technology has been gradually introduced in heath education. One of the most attractive features of this technology-based education is the use of multimedia. In this article we explore the research evidence about the role that multimedia is playing in education. From that analysis we describe the most relevant features of this technology to prepare a common ground of discussion about the evaluation of its impact on educational outcomes. As part of this analysis, we organize current research evidence on the use of technology in medical education, distinguishing diverse variables involved in the process, like knowledge (declarative, procedural), learner characteristics, curricular …

Blighting The Way: Urban Renewal, Economic Development, And The Elusive Definition Of Blight, Colin Gordon

Fordham Urban Law Journal

This article examines the way municipalities have used increasingly broad interpretations of "blight" to compete for state tax increment financing (TIFs) for economic development purposes. It traces the definition of blight in the context of state and federal urban redevelopment programs from the nineteenth century through the Progressive Era to the advent of TIF laws in the 1980s and 90s. It goes on to discuss the how the concept of "blight" has shifted from a condition of substandard housing to a condition of "sub-optimal" local economic development, in part due to intense competition among municipalities for TIFs. The article concludes …

Are Talebearers Really As Bad As Talemakers?: Rethinking Republisher Liability In An Information Age , Jennifer L. Del Medico

Fordham Urban Law Journal

This Comment critiques the legal landscape surrounding republisher liability for defamation and ultimately calls for a more reaching approach to protect against such liability. Historically at common law republishers could be held liable for defamation regardless of whether they attributed the source of the material. However, starting in 1933 courts articulated the “wire service defense” that sought to eliminate liability for republishers when they “republished a wire story from a generally recognized reliable source of daily news.” Subsequent to the 1933 Florida court’s articulation of the defense many jurisdictions have adopted it. New York stands out as one of the …

Bolling Alone, Richard A. Primus

Articles

Under the doctrine of reverse incorporation, generally identified with the Supreme Court's decision in Bolling v. Sharpe, equal protection binds the federal government even though the Equal Protection Clause by its terms is addressed only to states. Since Bolling, however, the courts have almost never granted relief to litigants claiming unconstitutional racial discrimination by the federal government. Courts have periodically found unconstitutional federal discrimination on nonracial grounds such as sex and alienage, and reverse incorporation has also limited the scope of affirmative action. But in the presumed core area of preventing federal discrimination against racial minorities, Boiling has virtually no …

Establishment Limitation Reduces Species Recruitment And Species Richness As Soil Resources Rise, M. Henry, H. Stevens, Stefan A. Schnitzer, Walter P. Carson

Biological Sciences Faculty Research and Publications

1. At local spatial scales, species richness tends to fall as productivity rises. Most explanations have focused on increased extinction, but, instead, we test experimentally whether increased soil fertility reduces recruitment. Specifically, we test whether variation in recruitment is due to source limitation, germination limitation or establishment limitation, and how litter accumulation and seed predation contribute to these processes.
2. We established four crossed experimental treatments in a perennial‐dominated early successional plant community over 3 years. We added seed of 30 species, manipulated access by selected seed predators, removed litter and added slow release fertilizer at four levels (0, 8, 16 and …

Comparison Of Harvested And Nonharvested Painted Turtle Populations, Tony Gamble, Andrew M. Simons

Biological Sciences Faculty Research and Publications

Painted turtles (Chrysemys picta) are commercially harvested in large numbers in Minnesota for sale to biological supply companies and the pet trade. We investigated the possible effects of this harvest by comparing size, demography, and catch rates of painted turtles in 12 harvested and 10 nonharvested painted turtle populations in 2001 and 2002. We correlated turtle catch rates to harvest status, and harvested lakes had a lower catch-per-unit-effort than nonharvested lakes. Harvest had minimal effect on the size of turtles captured, and we found no significant differences in the count of male:female:juvenile turtles among lakes of different harvest …

Climate Change In Arid Environments: Revisiting The Past To Understand The Future, Elena Lioubimtseva

Peer Reviewed Articles

Arid regions are expected to undergo significant changes under a scenario of climate warming, but there is considerable variability and uncertainty in these estimates between different scenarios. The complexities of precipitation changes, vegetation–climate feedbacks and direct physiological effects of CO2 on vegetation present particular challenges for climate change modelling of arid regions. Great uncertainties exist in the prediction of arid ecosystem responses to elevated CO2 and global warming. Palaeodata provide important information about the past frequency, intensity and subregional patterns of change in the world’s deserts that cannot always be captured by the climatic models. However, it is important to …

Mapping Of Thermo-Fluids Laboratory Experiments Into Web-Based Experiments, Sushil Chaturvedi, Rick Mckenzie, O. A. Akan, A. Priyadershini

Mechanical & Aerospace Engineering Faculty Publications

A methodology is being developed for transforming physical experiments from the undergraduate thermo-fluids laboratory into a web-based virtual experiments. Important characteristics of physical experiments are identified in order to preserve them in physical to virtual domain mapping. Several commercially available software are employed to incorporate in the web-based experiments characteristics such as recreation of physical phenomenon in the virtual domain, measurement of physical quantities on a computer screen, assembly of virtual probes and coupling of the virtual experiment with a data acquisition software. A virtual reality software has been incorporated to enable web-based students to navigate through the virtual laboratory, …

Welfare Law, Welfare Fraud And The Moral Regulation Of The 'Never Deserving' Poor, Shelley A. M. Gavigan, Dorothy E. Chunn

Articles & Book Chapters

The dismantling and restructuring of Keynesian social security programmes have impacted disproportionately on women, especially lone parent mothers, and shifted public discourse and social images from welfare fraud to welfare as fraud, thereby linking poverty, welfare and crime. This article analyzes the current, inordinate focus on 'welfare cheats'. The criminalization of poverty raises theoretical and empirical questions related to regulation, control, and the relationship between them at particular historical moments. Moral regulation scholars working within post-structuralist and post-modern frameworks have developed an influential approach to these issues,however, we situate ourselves in a different stream of critical socio-legal studies that takes …

The "Terminator" Patent And Its Discontents: Rethinking The Normative Deficit In Utility Test Of Modern Patent Law, Ikechi Mgbeoji

Articles & Book Chapters

Arguably, no other biotechnological invention has been excoriated with so much confused rhetoric on “utility” as the invention relating to Genetic Use Restriction Technologies (“GURTs”) patented in the United States, Canada, Australia, Belgium, Bulgaria, Denmark and many other countries. Otherwise known by their rather inflammatory nickname of both “terminator patents,” GURTs have become the lightning rod for both technophiles and Luddites. At the heart of the controversy is a misunderstanding of the changed meaning of the concept of utility in patent law. This paper argues that while the public understanding of utility as social usefulness is well grounded in history …

Motivation, Drug Abuse, And 50 Years Of Theoretical And Empirical Inquiry, Rick A. Bevins, Michael Bardo

Department of Psychology: Faculty Publications

In reviewing the 25-year history of the Nebraska Symposium on Motivation, Benjamin and Jones (1979) noted that the Symposium was "the longest-lived topical series in American psychology, with 'I national and international reputation" (p. ix). On March 28 and 29 of 2002, with a packed auditorium on the campus of the University of Nebraska-Lincoln, this record was doubled in life. As the reader will quickly see from the list of contributors, the reputation of the Symposium was also maintained on its 50th Anniversary. Before continuing, we would like to reiterate the thanks in the Preface for all those who supported …

Drive, Incentive, And Reinforcement: The Antecedents And Consequences Of Motivation, Roy Wise

Department of Psychology: Faculty Publications

The aim of scientific explanation is to characterize the important antecedents of observable (or at least objectively confirmable) events. Explanations of behavior in terms of motivational states are appeals to unobservable, internal events for interpretations of behavior that is variable under apparently constant external stimulus conditions (see, e.g., Brown, 1953; Hinde, 1960). To be identified as the cause of a behavior, the unobservable event or condition must preexist the behavioral event to be explained. A behavior cannot be explained by its consequences, though it may be explained as a consequence of similar events in the animal's history. Scientific explanation involves …

The Legality And Legitimacy Of Unilateral Armed Intervention In An Age Of Terror, Neo-Imperialism, And Massive Violations Of Human Rights: Is International Law Evolving In The Right Direction?, Jean-Gabriel Castel

Articles & Book Chapters

When the United Nations was created in 1945, its main purpose was to deal with threats to international peace and security in order to prevent states from waging aggressive wars. Today, especially since 9/11, terrorism, the spread of weapons of mass destruction, and internal conflicts involving massive violations of human rights are some of the new challenges confronting this organization. The Security Council, which is charged with the maintenance of international peace and security, has not been very consistent and quick in addressing these issues. As a result, when it has failed to authorize collective action, some states have resorted …
