Assessment Of Heavy Metal Concentrations In Water, Plankton, And Fish Of Lake Manzala, Egypt, Mohamed Bahnasawy, Abdel Aziz Khidr, Nadia Dheina

Turkish Journal of Zoology

The levels of some heavy metals (Cu, Zn, Cd, and Pb) were determined in water, plankton, and fish (Liza aurata) collected from 5 sites in Lake Manzala. Metals in the water and fish exhibited a significant seasonal and regional variation, in which all metals attained their maximum value during summer, while the lowest levels were found during winter. The concentration of different metals in water, plankton, and fish tissues followed the same order: Zn > Cu > Pb > Cd. The mean concentrations of metals in the water were as follow: Cu, 0.055; Zn, 0.311; Cd, 0.020; and Pb, 0.022 mg/L. The Cd …

Too Hot To Handle: Climate Change And Agricultural Water Use, Denise D. Fort

Faculty Scholarship

The world faces enormous challenges in responding to looming crises in food and water. Responding to this challenge will require flexibility; such flexibility may be impeded by legal institutions. This paper looks at the western United States and discusses the role of irrigated agriculture in that region. Because of climate change, a growing population, declining groundwater, the need to protect ecosystems and other conflicts, the author suggests that all water uses, including long-standing agricultural water rights, need to be examined in light of these changes. Legal systems have tended to serve the status quo, but perhaps the law can help …

The Fundamental Question When Applying The Welfare Principle: "Who Will Be The Better Parent Or Guardian"?, Siyuan Chen

Research Collection Yong Pung How School Of Law

The welfare principle – that is, when making a custody-related decision, the best interests of the child form the first and paramount consideration – is probably one of the cardinal principles of family law in many common law jurisdictions. While the welfare principle is generally considered a wide concept with no exhaustive definition or list of factors, it is submitted that there is an important question – sometimes neglected or misunderstood – that should actually feature most prominently when applying the welfare principle, particularly when joint or no order custody orders seem impossible. The question is simply that of “who …

Many researchers—even trained professionals—often use the Google search engine to begin searches for information. Google’s many products enable researchers to search public websites, scholarly articles, and even patents. One vast area of information not yet thoroughly indexed by Google is print books. Google Book Search (also at times referred to as Google Books, Google Print and Google Library Project) is the company’s effort to digitize and index the world’s print literature.

Negotiating Federalism, Erin Ryan

Faculty Publications

Bridging the fields of federalism and negotiation theory, Negotiating Federalism analyzes how public actors navigate difficult federalism terrain by negotiating directly with counterparts across state-federal lines. In contrast to the stylized, zero-sum model of federalism that pervades political discourse and judicial doctrine, the Article demonstrates that the boundary between state and federal power is negotiated on scales large and small, and on an ongoing basis. It is also the first to recognize the procedural tools that bilateral federalism bargaining offers to supplement unilateral federalism interpretation in contexts of jurisdictional overlap.

The Article begins by situating its inquiry within the age-old …

The Effects Of Coursecasting In International Freshman Students' Perceptions Of Marginality And Isolation, Anxiety, And English Language Oral Proficiency And Comprehension, Alberto Fernandez

CCAC Theses and Dissertations

The influx of international students attending American universities has put the U.S. at the forefront of international education, generating over $14.5 billion yearly.

International students often face adjustment issues impacting their level of satisfaction with their experience. These involve oral language proficiency, as well as feelings of anxiety and isolation resulting from language deficiencies, which increase their feelings of marginality. Engaged learning, which is dependent on comprehension, is affected by the anxiety students bring to class. It is believed that coursecasts may alleviate anxiety, thus improving student engagement in learning.

A pre-experimental research design investigates whether coursecasting mitigates feelings of …

A Study On Influence Of Borax To Polyester Insulators, Aysel Ersoy, Ayten Kuntman

Turkish Journal of Electrical Engineering and Computer Sciences

In this study the effect of borax on polyester insulators is investigated by evaluating the tracking and erosion resistance using the inclined plane test. The test procedure follows the ASTM D2303 standard. During the test, 50 Hz current was acquired from the ground electrode allowing a sampling rate of 48000 samples per second. The effect of borax concentration on the glass transition and the degradation temperature is studied by employing differential scanning calorimetry (DSC) analysis. The addition of borax to the unsaturated polyester resulted in an increase in the glass transition temperature, while the addition of 0.5% of borax by …

Work Intensity And Substance Use Among Adolescents Employed Part-Time In Entry-Level Jobs, Jessica Samuolis

Psychology Faculty Publications

This study investigated the relationship between number of hours worked, or work intensity, and substance use in a sample of adolescent employees of a supermarket chain. Employees working half-time or more per week (high-intensity hours) were over three times as likely to smoke compared to those working an average of 10 hours or less per week (low-intensity hours). Males working a high intensity number of hours were more than twice as likely to drink compared to males working at low intensity. Utilizing participants drawn from a uniform employment setting, the research findings add to the growing body of evidence linking …

Stray Magnetic Field Distributed Around A Pmsm, Ali̇ Ahmed Adam, Kayhan Gülez, Seli̇m Köroğlu

Turkish Journal of Electrical Engineering and Computer Sciences

In this work, the low frequency electromagnetic emission from permanent magnet synchronous motors is studied. The main objective is to provide a safety region for humans in the vicinity of these motors, especially as these motors are now being used widely in inhabited areas, where high flux densities are expected. In this study, a new proposed equivalent magnetic circuit is used to estimate the stray fields at the surface of the motor. The analysis showed that the emission of the stray field in the radial direction depends on the permeability of the stator body. Low values of permeability may result …

Recent Advances In The Synthetic And Mechanistic Aspects Of The Ruthenium-Catalyzed Carbon-Heteroatom Bond Forming Reactions Of Alkenes And Alkynes, Chae S. Yi

Chemistry Faculty Research and Publications

The group’s recent advances in catalytic carbon-to-heteroatom bond forming reactions of alkenes and alkynes are described. For the C–O bond formation reaction, a well-defined bifunctional ruthenium-amido catalyst has been successfully employed for the conjugate addition of alcohols to acrylic compounds. The ruthenium-hydride complex (PCy₃)₂(CO)RuHCl was found to be a highly effective catalyst for the regioselective alkyne-to-carboxylic acid coupling reaction in yielding synthetically useful enol ester products. Cationic ruthenium-hydride catalyst generated in-situ from (PCy₃)₂(CO)RuHCl/HBF₄·OEt₂ was successfully utilized for both the hydroamination and related C–N bond forming reactions of alkenes. For …

Fitness And Adiposity As Predictors Of Functional Limitation In Adults, Andréa L. Maslow, Anna E. Price, Xuemei Sui, Duck-Chul Lee, Ikka Vuori, Steven N. Blair

All PTHMS Faculty Publications

This study examined the associations of body mass index (BMI), waist circumference (WC), and cardiorespiratory fitness (CRF) with incident functional limitation (IFL) in adults. Patients (n = 2400), 30+ years [mean age, 45.2 (SD, 8.3); 12% women], completed a baseline health examination during 1979 to 1995. CRF was quantified by age-and sex-specific thirds for maximal treadmill exercise test duration. Adiposity was assessed by BMI and WC (grouped for analysis according to clinical guidelines). Incident IFL was identified from mail-back surveys during 1995, 1999, and 2004. After adjusting for potential confounders and either BMI or WC, CRF was inversely related to …

Taking The Risk Out Of Termination: An Enterprise Risk Management Analysis Of The Normative System Of Employment Standards Challenged By Honda V Keays, Ryan Henry Edmonds

Dalhousie Journal of Legal Studies

Over many years, Canadian courts have crafted a unique body of employment law jurisprudence. The purpose of this paper is to discuss how that jurisprudence was unraveled when the Supreme Court of Canada rendered its decision in Honda v. Keays. That holding, in effect, overturned aspects of Wallace v. United Grain Growers; a case that transformed how non-unionized employees were thought of and treated in Canadian society. This paper examines the analytical underpinnings of wrongful dismissal law’s previous regime on bad faith damages and juxtaposes it to the new regime in Keays, concluding that the shift in focus from employer …

Does The Charter Follow The Flag? Revisiting Constitutional Extraterritoriality After R V Hape, Chanakya Sethi

Dalhousie Journal of Legal Studies

Jacques Maritain, the noted philosopher and political thinker and a principal drafter of the Universal Declaration of Human Rights, once contended that “political philosophy must get rid of the word, as well as the concept, of Sovereignty.” He reasoned as much “not because [sovereignty] is an antiquated concept,” or “because the concept of Sovereignty creates insuperable difficulties and theoretical entanglements in the field of international law,” but because “this concept is intrinsically wrong and bound to mislead us if we keep on using it.” Maritain’s proposal may have been exceedingly bold and his criticisms perhaps too harsh, but they nonetheless …

Risk V Benefits: The Use Of Selective Serotonin Reuptake Inhibitors In Children, Kim Wilton

Dalhousie Journal of Legal Studies

Selective Serotonin Reuptake Inhibitors (SSRIs) are a class of antidepressant medications that came on the market in the late eighties and early nineties. SSRIs were found to be clinically effective in treating clinical depression, and anxiety disorders in adults and had less cumbersome side effects compared to the older Tricyclic antidepressants. The first drug in this class introduced was fluoxetine (Prozac), which was soon followed by paroxetine (Paxil), sertraline (Zoloft), citalopram (Celexa), fluvoxamine (Luvox), and escitalopram (Lexapro). Today the uses of SSRIs have broadened to include treatment for “Post-Traumatic Stress Disorder, pre-menstrual dysphoric disorder, urinary incontinence” and many other seemingly …

The Patentability Of Human Embryonic Stem Cells: Is The Inconsistent Application Of The European Union Biotechnology Directive's Moral Exclusion Clause Undermining Investor Confidence In Europe, Providing A Competitive Advantage To The United States?, Stephen R. Donnelly

Dalhousie Journal of Legal Studies

The original justification for Directive 98/44/EC of the European Parliament and of the Council of 6 July 1998 on the Legal Protection of Biotechnological Inventions (the Directive) was to promote the growth of the European life science sector by harmonizing and clarifying European biotechnology patent laws. As early as 1985, the European Commission had identified the fragmentation of European patent laws as a potential problem. The Directive thus aimed to address obstacles to the unity of the internal market, which would arise if national Member States adopted divergent and uncoordinated policies and legislation in a field of economic activity that …

Turning Citizens Into Subjects: Why The Health Insurance Mandate Is Unconstitutional, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

In 2010 something happened in this country that has never happened before: Congress required that every person enter into a contractual relationship with a private company. While the author realizes that writers make lots of factual claims that readers are wise to be skeptical about, he proves that an economic mandate like this one is unprecedented. If this mandate had ever happened before, everyone reading this passage would know all the contracts the federal government requires them to make, upon pain of a penalty enforced by the Internal Revenue Service (IRS). No reader, however, can recite any such mandate and …

Legislative Organization And Administrative Redundancy, Michael Doran

Georgetown Law Faculty Publications and Other Works

Congress regularly enacts legislation providing for redundant administrative programs. For example, there are more than 100 federal programs for surface transportation, 82 programs to ensure teacher quality, 80 programs to promote domestic economic development, and 47 programs to provide employment and job-training services. Recent high-profile legislation–-such as the financial-industry reform measure and the health-care reform measure–-add new programs without repealing existing ones directed at the same policy goals. Prior academic analyses generally have not considered why Congress pursues redundancy. This article addresses that question through both theoretical and institutional analysis.

The article first constructs an organizational theory that attributes redundancy …

Misunderstanding Congress: Statutory Interpretation, The Supermajoritarian Difficulty, And The Separation Of Powers, Victoria Nourse

Georgetown Law Faculty Publications and Other Works

Every lawyer's theory of statutory interpretation carries with it an idea of Congress, and every idea of Congress, in turn, carries with it an idea of the separation of powers. In this article, the author critiques three dominant academic theories of statutory interpretation--textualism, purposivism, and game theory--for their assumptions about Congress and the separation of powers. She argues that each academic theory fails to account for Congress's dominant institutional features: "the electoral connection," the "supermajoritarian difficulty," and the "principle of structure-induced ambiguity." This critique yields surprising conclusions, rejecting both standard liberal and conservative views on statutory interpretation.

"Plain" meaning, it …

Emotion, Neuroscience, And Law: A Comment On Darwin And Greene, John Mikhail

Georgetown Law Faculty Publications and Other Works

Darwin’s (1871) observation that evolution has produced in us certain emotions responding to right and wrong conduct that lack any obvious basis in individual utility is a useful springboard from which to clarify the role of emotion in moral judgment. The problem is whether a certain class of moral judgments is “constituted” or “driven by” emotion (Greene 2008, p. 108) or merely correlated with emotion while being generated by unconscious computations (e.g., Huebner et al. 2008). With one exception, all of the “personal” vignettes devised by Greene and colleagues (2001, 2004) and subsequently used by other researchers (e.g., Koenigs et …

Accreditation Reconsidered, Judith C. Areen

Georgetown Law Faculty Publications and Other Works

Higher education is one of the most successful sectors in the nation at a time when much of the economy is struggling. Its quality has been buoyed by a long tradition of investment, both public and private, and by a healthy degree of autonomy from governmental control. America’s three governance innovations, citizen governing boards, shared governance, and accreditation, also have encouraged both quality and institutional autonomy in higher education.

Accreditation has been a particularly important contributor to the institutional diversity and vitality of American colleges and universities. Most nations have a ministry of education that oversees institutions of higher education. …

Biosafety Concerns Involving Genetically Modified Mosquitoes To Combat Malaria And Dengue In Developing Countries, Graciela R. Ostera, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

Malaria and dengue are the most prevalent mosquito-borne infections worldwide. Because traditional vector control methods have proven to be insufficient to control mosquito populations in endemic areas, scientists are actively working in the design of new strategies, such as genetically modified (GM) mosquitoes, to reduce disease transmission. The replacement of natural populations with GM mosquitoes is becoming a tangible possibility, however, many fear that the release of these organisms into the environment could constitute a significant risk to biodiversity and may cause the unintended spread of GM organisms across national borders.

The Cartagena Protocol on Biosafety, an international agreement originally …

Doing Too Much: The Standard Deduction And The Conflict Between Progressivity And Simplification, John R. Brooks

Georgetown Law Faculty Publications and Other Works

In U.S. federal income tax, the standard deduction, along with the personal exemptions, provides taxpayers with a minimum amount of untaxed income, effectively creating a "zero bracket amount." For historical and political reasons, however, the standard deduction also operates as a simplified substitute for the itemized deductions, such as the deductions for extraordinary medical expenses, charitable contributions, and home mortgage interest. This seemingly reasonable compromise in fact leads to substantial, and surprising, conceptual complexity. In particular, close analysis of each of the two roles shows that their effects, and related criticisms, are often contradictory, which in turn makes it difficult, …

Unearthing The Inner Compass, Kimberly Ann Kapalka

Graduate Student Theses, Dissertations, & Professional Papers

The process of composing a body of artwork was to prove my artistic ability and prepare work for submission to artist-in-residence programs. To achieve this goal, I committed eleven months to this project. Inspiration for pieces came from my travels, interests in American Indian culture, wildlife, trees, photographs, and still-life objects. I devoted as much time as possible in my make-shift apartment studio working on art. Balancing career and home activities was a habitual challenge. I learned to trust my intuition while creating art making choices that reflected my intended message. Fear of public opinion floated through my mind as …
