On The Links Between Managerial Actions, Keystone Species, And The Resilience Of Ecological-Economic Systems, Amitrajeet A. Batabyal

Articles

Managerial actions influence the survival probabilities of the keystone species of an ecological-economic system. In turn, the well-being of these keystone species translates into the well being or the resilience of the underlying ecological-economic system. What are the theoretical links between managerial actions, keystone species, and the resilience of ecological-economic systems? Recently, Batabyal (2002) has addressed aspects of this question. In this paper, we extend the analysis in Batabyal (2002). First, we use a stochastic model to delineate a stylized ecological-economic system. Next, we discuss the links between managerial actions, keystone species, and this ecological-economic system’s resilience. Finally, we show …

Book Review Of Gender On Trial: Sexual Stereotypes And Work/Life Balance In The Legal Workplace, Nicole Buonocore Porter

Faculty Publications

Holly English's book, Gender on Trial: Sexual Stereotypes and Work/Life Balance in the Legal Workplace, offers a very interesting, albeit mostly anecdotal, look at the many real or perceived sexual stereotypes in the legal workplace. Her book is the result of interviews with 180 lawyers (fifty of them men) over a two-year period in all regions of the country. Her main purpose of the book was to "explore the fact that persistent gender stereotypes present a continuing obstacle that obstructs the availability of broad opinions and choices for men and women lawyers." Through eight substantive chapters, she seeks to explore …

Throwing Caution To The Wind: The Precautionary Principle, Nafta And Environmental Protection In Canada, Paul Guy

Dalhousie Journal of Legal Studies

According to the precautionary principle, the lack of full scientific certainty should not preclude measures to prevent environment degradation. This principle has been incorporated into numerous international instruments and is approaching the status of customary international law. Moreover, the Canadian government has embraced the principle and the Supreme Court of Canada recently confirmed it as a basis of environmental policy in 114957 Canada Ltée (Spraytech, Société dʼ’arrosage) v. Hudson (Town). This paper examines the ability of the precautionary principle to actually function as a guide for environmental policy in light of Canadaʼs international trade obligations. In particular, it considers Canadaʼs …

Pandemic Influenza: Public Health Preparedness For The Next Global Health Emergency, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

Severe Acute Respiratory Syndrome (SARS) garnered a great deal of public attention because it was novel and its potential for spread was unknown. However, the SARS corona virus is significantly less virulent than pandemic influenza viral infections. The annual number of deaths for seasonal influenza is 36,000 people in the United States and 250,000- 500,000 worldwide. However, highly pathogenic influenza pandemics have occurred roughly 2-3 times per century, causing untold morbidity and mortality. The Spanish influenza pandemic of 1918 was believed to have caused over 20 million deaths in a world less than one-third the size of the current global …

Deliberate Extinction: Whether To Destroy The Last Smallpox Virus, David A. Koplow

Georgetown Law Faculty Publications and Other Works

The target problem to be examined is smallpox. Specifically, what should we (the United States and the entire world) now do with the last known residual samples of the virus that causes this uniquely horrific disease? The illness itself has virtually disappeared from the catalogue of human afflictions: due to a stunningly imaginative, concerted, and resolute campaign of the World Health Organization (WHO) through the 1970s, no one has contracted this deadly impairment for twenty-five years. Yet the causative element, an insidious scourge known as the variola virus, still remains, housed for now in high-security freezers at the U.S. Centers …

A Theory Of Crimes Against Humanity, David Luban

Georgetown Law Faculty Publications and Other Works

The answer I offer in this Article is that crimes against humanity assault one particular aspect of human being, namely our character as political animals. We are creatures whose nature compels us to live socially, but who cannot do so without artificial political organization that inevitably poses threats to our well-being, and, at the limit, to our very survival. Crimes against humanity represent the worst of those threats; they are the limiting case of politics gone cancerous. Precisely because we cannot live without politics, we exist under the permanent threat that politics will turn cancerous and the indispensable institutions of …

Linkage Of Arcview Gis With The Rzwqm

Journal of Spatial Hydrology

The Root Zone Water Quality Model (RZWQM) is a one-dimensional, lumped field-scale model. It can simulate major physical, chemical, and biological processes in an agricultural crop production system. While its reliability has been verified by several researchers, because of its lumped structure RZWQM could not account for the soil heterogeneity and the associated nonuniformity of management practices across the field. Neglecting the variability may result in misleading simulation results. On the other hand, the variability can be accurately characterized by using a geographic information system (GIS), especially ArcView GIS, the most widely used desktop mapping and geographic analysis system. Linked …

Étude Des Facteurs Environnementaux Et Physiologiques Contribuant À La Variabilité Biologique : Caractérisation De La Relation « Exposition - Indicateur Biologique D'Exposition » Pour Le N-Hexane, Geneviève Hamelin, Robert Tardif, Ginette Truchon

Rapports de recherche scientifique

Jusqu'à tout récemment, l'American Conference of Governmental Industrial Hygienists (ACGIH) recommandait d'utiliser la mesure de la 2,5-hexanedione (2,5-HD) totale (2,5-HD libre + autres conjugués glucuronides) comme indicateur biologique de l'exposition (IBE) au n-hexane (n-HEX). En 2001, l’ACGIH a cependant proposé de recourir plutôt à la mesure de la 2,5-HD libre uniquement et la valeur du nouvel indicateur serait de 3.5 µmol/L. Le choix de cette mesure se justifie puisque la 2,5-HD libre est le métabolite responsable des effets neurotoxiques associés à l'exposition au n-HEX. De plus, la mesure de la 2,5-HD libre permet une meilleure discrimination entre individus exposés et …

Intergenerational Preferences Regarding Punishment Of Criminal Offenders, Allison Deutsch, Molly Movall, Christine Van Berkum

Presidential Scholars Theses (1990 – 2006)

The purpose of this study is to examine intergenerational differences regarding corporal punishment of criminal offenders, particularly preferential differences that occur between members of the Baby Boom and Echo-Baby Boom generations. This research is of interest due to America 's changing culture. The children of Baby Roomers see fewer acts and practices as sinful and morally wrong than do their parents, and our research examines if similar changes occurred in the criminal justice system in response to how offenders should be punished. No studies currently exist which examine this issue, and this research will create awareness in the discipline of …

Our Toxics Regulatory System And Why Risk Assessment Does Not Work: Endocrine Disrupting Chemicals As A Case In Point, Valerie J. Watnick

Utah Law Review

Our current toxics regulatory system is based on the fundamental premise that the public expects a high degree of safety-close to absolute safety 2-in the regulation of toxins in our environment. To implement a system based on this fundamental assumption, we assume further that we can use risk assessment to develop "health-based" safety standards and use command and control regulation to implement them. This Article suggests that the fundamental premise that we can and should develop and apply standards that ensure safety to human health in our toxics regulatory schemes has little basis in current political and scientific reality. Politically, …

Soils Of Regeneration: Exploring Conceptualizations Of The Natural World As A Context For An Ecologically-Sensitive Curriculum, Emily A. Demoor

LSU Doctoral Dissertations

David Orr (1994) asserts that the ecological crisis is a crisis of education. This study explores the relationship between the ecological crisis and education by examining the role that language plays in shaping perceptions of the natural world. Toward this end it analyzes narratives of science, literature and other disciplines that conceptualize the natural world as object and as subject. It evaluates how particular metaphors used in reference to the natural world enhance or impede ecological understanding and the cultivation of responsibility and stewardship and considers ways in which these conceptualizations might be used as a basis for new curriculum …

Activity-Based Anorexia: The Effects Of Resistant Starch, Holly M. Nguyen

LSU Master's Theses

Anorexia nervosa is the third most common illness among adolescent females. Approximately one half the cases of anorexia nervosa have been suggested to be activity-induced. Various animal studies have been used to study human anorexia, particularly the activity-based anorexia model (ABA). The ABA paradigm consists of diet restriction and liberal access to activity, which ultimately results in a rapid decrease in both body weight and food intake paradoxical to the significant increase in activity. Because resistant starch (RS) has been shown to initiate a lower rise and a steady level of post-prandial blood glucose, it was hypothesized that a diet …

Line Drive: L1 Element Orthologous Loci, Huei Jin Ho

LSU Master's Theses

The L1Hs preTa subfamily is one of the youngest L1 families. It originated after the divergence of human and chimpanzee about 2.34 mya, and therefore is only found in the human genome. Some elements were inserted so recently that they are not fixed in the population. Thirty three of the 254 L1Hs preTa elements are polymorphic for the absence/presence of the insertion, making them useful markers for studying phylogenetics and human population genetics. However, the problem of homoplasy can diminish the value of using L1 elements as phylogenetic and population genetic markers. Examination of the L1Hs preTa orthologous insertion sites …

Synthesis And Antibacterial Assessment Of Water-Soluble Hydrophobic Chitosan Derivatives Bearing Quaternary Ammonium Functionality, Mrunal R. Thatte

LSU Doctoral Dissertations

Chitosan is a naturally occurring, bio-degradable, non-toxic, non-allergenic bio-polysaccharide derived from chitin, found in abundance in nature. Studies aimed at deriving newer applications of chitosan are hence of interest. Among these, one of the focuses of investigations is aimed at excellent antimicrobial activity demonstrated by chitosan. In this context, certain quaternary ammonium derivatives of chitosan have been shown in the past to be highly effective antibacterial materials. In the present study, substituted chitosan derivatives were synthesized and further quaternized using Quat-188 to produce water soluble derivatives at neutral pH. The antibacterial assessments of the quaternized derivatives of substituted chitosan were …

The Impact Of Brief Intervention On Adherence To Medication Regimen Of Low-Income Adults With Type 2 Diabetes, Kathleen E. Kendra

LSU Master's Theses

Patient nonadherence with medication regimen is a common problem facing health care providers treating adult patients with Type 2 diabetes. Poor glycemic control, diabetes related complications, and increased utilization and health care costs are among the outcomes of poor compliance with medical regimen. Prior research indicates moderate success with several techniques to improve medication adherence when used alone. However, the literature suggests a need for an intervention providing a multi-component technique, implementing self-motivating skills and follow-up prompts. Using a 15- minute single exposure intervention, the current study attempted to combine these two procedures (brief intervention including motivational interviewing with follow-up …

Tissue Interactions With Lasers And Liquid Nitrogen: A Novel Cryopreservation Method, Deepak Kandra

LSU Master's Theses

The importance of the imposed cooling rate in cryopreserving native cells and tissues has been long recognized in the field of cryobiology. When biological tissues are subjected to cooling rates in excess of thousands of degree C per minute, the characteristic structural and physical manifestations of the ice formed are such that the traditional damage due to ice formation at lower cooling rates are suppressed. Hence, achieving high cooling rates in tissues and cells of biologically relevant sizes (mm’s and cm’s) has been a long standing research problem. In the present study, we present a novel technique to achieve high …

What Do Tin-Enameled Ceramics Tell Us?: Explorations Of Socio-Economic Status Through The Archaeological Record In Eighteenth-Century Louisiana: 1700-1790, Jason A. Emery

LSU Master's Theses

This thesis examines the presence and distribution of tin-enameled earthenwares in what was colonial Louisiana at nine archaeological sites: Madame John's Legacy (16OR51), the ca. 1730s French Colonial Barracks (16OR136), the Lower Pontalba Building (16OR209), Galveztown (16AN39), French Site I (16PC80), the Bicentennial Gardens (22AD999), Los Adaes (16NA16), the American Cemetery (16NA67), and the Chamard House site (16NA100). To examine the ceramic diversity, a comprehensive classificatory system is proposed, with discussion and classification of vessel forms. Ceramic diversity was anticipated to be patterned following geographic and economic lines; however, this was not substantiated through the analysis of the general body …

Color, Texture And Rehydration Characteristics Of Ohmically Treated Sweet Potatoes, Sireesha Bhattiprolu

LSU Master's Theses

Ohmic heating has been shown to affect the drying rate and texture of foods. This research was designed to determine the effect of ohmic heating on rehydration, color and texture properties of sweet potatoes. Three combinations: 60Hz, 40V, 60Hz, 60V and 1Hz, 40V were applied to ohmically heat sweet potato cubes. The ohmic treated cubes and untreated cubes or controls were stored for six days in four different %relative humidities of 11.15%, 32.73%, 57.70% and 75.32%. Results showed that there was no significant difference in the rehydration properties of ohmic treated samples and control samples. The % moisture gain varied …

Quality Assurance Testing Of The Eclox-M In Detecting Terrorism Threats In Louisiana's Public Drinking Water Systems, Jessica Coleman

LSU Master's Theses

A quality assurance testing of the ECLOX-M™, a rapid water quality indicator used in potential terrorist attacks, was evaluated for its adequacy in nine regional Louisiana water systems. The ECLOX-M™ system uses enhanced chemiluminescence to measure toxicity in water by integration of a mixture of luminol (C₈H₇O₃N₃), and an oxidant in the presence of a catalyst enzyme - horseradish peroxidase (HRP). Water samples were tested for chemiluminescence, chlorine content, pH, and arsenic and/or nerve agent/pesticide contamination. In addition, three toxic industrial chemical standards were evaluated (mercury, a volatile liquid mixture, and a …

The Use Of Altrenogest To Control Reproductive Function In Beef Cattle, Clarence Edward Ferguson

LSU Doctoral Dissertations

There has been great controversy involving progesterone (P₄) levels during early pregnancy in cattle. The objectives of these experiments were to determine the effect of an early low dose administration of P₄ or altrenogest (ALT) on pregnancy rates in repeat breeder (RPB) females, if an increase in pregnancy rates could result from a direct effect of P₄ on the embryo and if ALT could support pregnancy in the absence of a functional CL. Firstly, ALT was evaluated for use as a progestin in cattle by synchronizing estrus in beef heifers. There were no differences in the …

Synthesis, Characterization And Study Of Novel Reagents For The Detection Of Saccharides And Amino Acids, Nadia Nadette St. Luce

LSU Doctoral Dissertations

The design of synthetic receptors for the recognition and sensing of saccharides and amino acids is currently a major challenge. This is due to inherent structural similarity and a lack of chromophoric or fluorophoric properties of these compounds. The synthesis and study of novel detection agents for bioactive molecules as well as mechanistic studies are presented herein. The elucidation of the mechanism by which tetraarylboronic acid resorcinarene interact with sugar molecules and promote a solution color change is explored. This vast collaborative study, reveals that DMSO solutions of boronic acid functionalized resorcinarene macrocycles afford visual color changes upon heating or …

Photo-Control Of Dna Oligonucleotides With Cage Compounds, Bilal Ghosn

LSU Master's Theses

Many biochemical processes in which DNA and other nucleic acids participate are central to functions in both living cells and in molecular biology assays. While many compounds have been used to regulate the activity of DNA, these strategies are limited to the aqueous-based diffusion of the activator to the target DNA molecule. An improvement to the induction of DNA bioactivity is to move to a light-based modulation. This research demonstrates a light-based technique using a photo-cleavable cage compound to transiently inactivate DNA hybridization. Function can be restored with exposure to near-UV light, allowing for temporal control of DNA oligonucleotide (ODN) …
