Censoring Crimes, Barak Y. Orbach, Allison S. Woolston Jan 2011

Censoring Crimes, Barak Y. Orbach, Allison S. Woolston

Cardozo Arts & Entertainment Law Journal

Concerns regarding the harmful influence of films on youth and adults have always motivated censorship and justified, in some minds, greater government control over content. Many motion pictures portray illegal conduct-theft, robbery, embezzlement, arson, drug dealing, assault, rape, murder, treason, and other crimes. In most instances, commission of the underlying crime is not needed for the production of the film. Despite the perpetual fear of the "capacity for evil" of films, the legality of motion pictures that commercialize crimes has not been studied as a concept. This Essay explores the reasons for this neglect and examines the problems this omission …

Forage Nutritional Quality Evaluation Of Bahiagrass Selections During Autumn In Florida, Robert Myer, Ann Blount, Samuel Coleman, Jeffery Carter

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Bahiagrass (Paspalum notatum Flugge) is the major pasture forage in the southern Gulf Coast, USA. A bahiagrass selection breeding program has been ongoing since 1960 at the Coastal Plain Experiment Station at Tifton, Georgia, USA, to increase forage yield in Pensacola (P. notatum var. sanese) bahiagrass. However, the impact of selecting for forage yield on forage nutritional quality is unknown. Forage quality was evaluated on four Pensacola derived selection cycles (C) of bahiagrass [C0 (Pensacola), C4, C9 (Tifton 9), and C23]. A total of 175 plants per cycle were grown. Forage from individual 1-year-old plants was harvested by …

In 2007, Vietnam experienced swine disease outbreaks causing clinical signs similar to the ‘porcine high fever disease’ that occurred in China during 2006. Analysis of diagnostic samples from the disease outbreaks in Vietnam identified porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV-2). Additionally, Escherichia coli and Streptococcus equi subspecies zooepidemicus were cultured from lung and spleen, and Streptococcus suis from one spleen sample. Genetic characterization of the Vietnamese PRRSV isolates revealed that this virus belongs to the North American genotype (type 2) with a high nucleotide identity to the recently reported Chinese strains. Amino acid …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

As a consequence of continued spillover of Mycobacterium bovis into cattle from wildlife reservoirs and increased globalization of cattle trade with associated transmission risks, new approaches such as vaccination and novel testing algorithms are seriously being considered by regulatory agencies for the control of bovine tuberculosis. Serologic tests offer opportunities for identification of M. bovis-infected animals not afforded by current diagnostic techniques. The present study describes assay development and field assessment of a new commercial enzyme-linked immunosorbent assay (ELISA) that detects antibody to M. bovis antigens MPB83 and MPB70 in infected cattle. Pertinent findings include the following: specific antibody responses …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Due to a close genetic relatedness, there is no known antibody that detects Mycobacterium avium subspecies paratuberculosis (MAP), which causes Johne’s disease in cattle and sheep, and does not cross-react with other M. avium subspecies. In the present study, a monoclonal antibody (MAb; 17A12) was identified from mice immunized with a cell membrane fraction of MAP strain K-10. This antibody is 100% specific as it detected a 25-kDa protein in all 29 MAP whole cell lysates, but did not bind to any of the 29 non- paratuberculosis strains tested in immunoblot assays. However, the antibody revealed variable reactivity levels in …

Fluid Fertilizer’S Role In Sustaining Soils Used For Bio-Energy Feedstock Production, John L. Kovar, Douglas L. Karlen Jan 2011

Fluid Fertilizer’S Role In Sustaining Soils Used For Bio-Energy Feedstock Production, John L. Kovar, Douglas L. Karlen

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The use of corn (Zea mays L.) as a bio-energy feedstock has attracted the attention of many producers. Recently, the focus has shifted from grain-based to cellulose-based ethanol production. In addition to biological conversion of corn stover to ethanol, thermal conversion (pyrolysis) of stover is being explored. Regardless of post-harvest processing, the short- and long-term effects of both increasing grain yields and removing stover on soil nutrient cycling, physical properties, and biological activity must be understood to ensure that soil productivity and ecosystem services are maintained. Our objectives for 2010 were to evaluate: (i) the use of surface or …

Effect Of Soybean Oil Fatty Acid Composition And Selenium Application On Biodiesel Properties, Benjamin D. Fallen, Vincent R. Pantalone, Carl E. Sams, Dean A. Kopsell, Steven F. Vaughn, Bryan R. Moser

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Biodiesel consisting principally of monounsaturated fatty acid methyl esters (FAME) has been reported to have the optimal balance between cold flow properties and oxidative stability, therefore producing a superior fuel. In addition, treating biodiesel with antioxidants such as selenium (Se) also increases oxidative stability. Fuel properties including acid value (AV), cloud point (CP), iodine value (IV), pour point (PP), peroxide value (PV), induction period (IP), onset temperature (OT), and kinematic viscosity (KV) were used to evaluate a newly developed Roundup Ready® soybean recombinant inbred line (RIL) and a commercial cultivar. The RIL had a fatty acid profile with elevated …

Pesticide Movement, Timothy J. Gish, Jared Williams, John H. Prueger, William Kustas, Lynn G. Mckee, Andy Russ

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Pesticides generally include herbicides, insecticides, and fungicides and play an important role in maintaining worldwide food and fiber production by controlling weeds that compete for water and nutrients or by eliminating pests that reduce yields (Majewski and Capel, 1995). In the future, the role of pesticides and fertilizers in agriculture is likely to increase as marginal land is converted to agriculture to meet production needs (Helling, 1993). Furthermore, it has also been proposed that increasing food and fiber production by agriculture will be critical to maintaining political and social stability in many countries (Tilman et al., 2002). However, pesticides can …

Cultural Understandings Of Risk And The Tyranny Of The Experts, Molly J. Walker Wilson Jan 2011

Cultural Understandings Of Risk And The Tyranny Of The Experts, Molly J. Walker Wilson

All Faculty Scholarship

Every year, law-makers and agency regulators, with the input of industry experts and scientists, make hundreds of decisions about how to regulate conduct and allocate resources to address various types of risks that threaten the well-being of American citizens. In fact, managing and minimizing risk is one of the most important tasks of today’s policy-makers. In spite of this fact, most actions are taken without systematic consideration of the preferences of the very people whose welfare is at stake. There are two reasons for this. First, the dominance of Traditional Risk Analysis, with its emphasis on statistics and cost-benefit analysis, …

Saving The Sagebrush Sea: An Ecosystem Conservation Plan For Big Sagebrush Plant Communities, Kirk W. Davies, Chad S. Boyd, Jeffrey L. Beck, Jon D. Bates, Tony J. Svejcar, Michael A. Gregg

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Vegetation change and anthropogenic development are altering ecosystems and decreasing biodiversity. Successful management of ecosystems threatened by multiple stressors requires development of ecosystem conservation plans rather than single species plans. We selected the big sagebrush (Artemisia tridentata Nutt.) ecosystem to demonstrate this approach. The area occupied by the sagebrush ecosystem is declining and becoming increasingly fragmented at an alarming rate because of conifer encroachment, exotic annual grass invasion, and anthropogenic development. This is causing rangewide declines and localized extirpations of sagebrush associated fauna and flora. To develop an ecosystem conservation plan, a synthesis of existing knowledge is …

Anointing Chemicals And Hematophagous Arthropods: Responses By Ticks And Mosquitoes To Citrus (Rutaceae) Peel Exudates And Monoterpene Components, Paul J. Weldon, John F. Carroll, Matthew H. Kramer, Robert H. Bedoukian, Russell E. Coleman, Ulrich R. Bernier

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Some birds and mammals roll on or wipe themselves with the fruits or leaves of Citrus spp. or other Rutaceae. These anointing behaviors, as with anointing in general, are thought to function in the topical acquisition of chemicals that deter consumers, including hematophagous arthropods. We measured avoidance and other responses by nymphal lone star ticks (Amblyomma americanum) and adult female yellow fever mosquitoes (Aedes aegypti) to lemon peel exudate and to 24 volatile monoterpenes (racemates and isomers), including hydrocarbons, alcohols, aldehydes, acetates, ketones, and oxides, present in citrus fruits and leaves in order to examine their …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Death camas (Zigadenus spp.) is a common poisonous plant on foothill rangelands in western North America. The steroidal alkaloid zygacine is believed to be the primary toxic component in death camas. Poisonings on rangelands generally occur in the spring when death camas is abundant, whereas other more desirable forage species are limited in availability. In most cases where livestock are poisoned by plants in a range setting, there is more than one potential poisonous plant in that area. One common poisonous plant that is often found growing simultaneously in the same area as death camas is low larkspur ( …

Detection And Quantification Of Poliovirus Infection Using Ftir Spectroscopy And Cell Culture, Felipe T. Lee-Montiel, Kelly A. Reynolds, Mark R. Riley Jan 2011

Detection And Quantification Of Poliovirus Infection Using Ftir Spectroscopy And Cell Culture, Felipe T. Lee-Montiel, Kelly A. Reynolds, Mark R. Riley

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background: In a globalized word, prevention of infectious diseases is a major challenge. Rapid detection of viable virus particles in water and other environmental samples is essential to public health risk assessment, homeland security and environmental protection. Current virus detection methods, especially assessing viral infectivity, are complex and time-consuming, making point-of-care detection a challenge. Faster, more sensitive, highly specific methods are needed to quantify potentially hazardous viral pathogens and to determine if suspected materials contain viable viral particles. Fourier transform infrared (FTIR) spectroscopy combined with cellular-based sensing, may offer a precise way to detect specific viruses. This approach utilizes infrared …

Sonic Pleasure, Absence And The History Of The Self: An Alternative Approach To The Criticism Of Sound Art, Jonathan W. Marshall Jan 2011

Sonic Pleasure, Absence And The History Of The Self: An Alternative Approach To The Criticism Of Sound Art, Jonathan W. Marshall

Sound Scripts

Historical, psychoanalytic and cinema criticism have characterised the history of Western modernity and the individual subject as founded upon an affective lack. Pleasure is solicited by the promise of fullness, but this is never fulfilled, fuelling further desire. Sound art however is more typically theorised as inherently present and immersive, as a form that offers direct experience, which literally touches the subject. I draw upon the work of Jonathan Sterne, Steven Connor, psychoanalysis and film criticism to rearticulate not just modernist media and subjectivity as characterised by lack and absence, but the perception of aestheticised sound. Starting with an analysis …
