Un/Commonplaces: Redirecting Research And Curricula In Rhetoric And Writing Studies, Brian J. Mcnely

Open Access Theses & Dissertations

Un/Commonplaces is guided by a broad and fundamental question of inquiry regarding writing and disciplinary research: how can some of the predominant ways that our discipline has approached writing be retheorized to better approximate the complexity of contemporary rhetorical knowledge work? A corollary inquiry explores the resonances with English Studies that persist--and seeks to uncover how they persist--in our field. I argue that we can negotiate such issues by tracing and troubling some of our core disciplinary commonplaces, those commonsense notions and practices too frequently and easily adopted from English Studies and perpetuated within the often tumultuous and hegemonic relationship …

Claiming The Discursive Self: Mestiza Rhetoric Of Mexican Women Jouranlists, 1876-1924, Cristina Devereaux Ramirez

Open Access Theses & Dissertations

In the last two decades, scholars in Rhetoric and Writing Studies have been calling for a greater representation of voices of those from other cultures who participated in rhetorical practices. As Jacqueline Jones Royster contends, rhetoric has been framed as mostly white, male, and elite, and that these positions distort the democratic perspective of our discipline. Claiming the Discursive Self: Mestiza Rhetoric of Mexican Women Journalists, 1876-1924 presents women rhetors who were participating in not only creating a national identity, but also in constructing a public identity that would insure women's contribution and participation for future generations. It closely examines …

Scott V. Harris And The Role Of The Jury In Constitutional Litigation, Michael Wells

Scholarly Works

Suits brought under 42 U.S.C. section 1983 to recover damages for excessive force by the police bear some resemblance to common law tort litigation, since the key Fourth Amendment issue is whether the force was 'unreasonable.' In ordinary negligence law the jury typically decides whether an actor has exercised reasonable care, even when there is no dispute as to the facts. In section 1983 litigation the federal courts are badly split on the allocation of decision making between judge and jury, sometimes even within a particular circuit. The Supreme Court recently faced the judge-jury issue in Scott v. Harris, where …

International Common Law: The Soft Law Of International Tribunals, Timothy L. Meyer, Andrew T. Guzman

Scholarly Works

Rising legalization in the international community has lead to greater use of international tribunals and soft law. This paper explores the intersection of these instruments. The decision of an international tribunal interprets binding legal obligations but is not itself legally binding except, in some instances, as between the parties. The broader, and often more important function of a tribunal's decision - its influence on state behavior beyond the particular case and its impact on perceptions regarding legal obligations - is best characterized as a form of soft law.

Despite its inability to bind states, a tribunal can influence state behavior …

Baruch The Scribe: Preserver Of Knowledge And Model For Librarians, Roger White Ed.D.

The Christian Librarian

This article discusses how the Old Testament character Baruch serves as an inspiration for contemporary Christian librarians. Events from his scribal career parallel several common experiences of library professionals including archiving materials, maintaining and promoting a collection, dealing with criticisms from administrators and community leaders, and becoming weary from overwork. How he handled himself in the midst of these activities is noteworthy as is God’s response to his service. The life and legacy of Baruch provide several parallels and encouraging lessons applicable to all those called to serve in libraries.

Retooling The Profession: Librarianship In An Era Of Accountability And Competition, Gregory A. Smith

The Christian Librarian

Librarianship has changed substantially in recent years. We who work in libraries must continually acquire new knowledge and skills. We must adapt to the reality that academic libraries, along with their parent institutions, face increased accountability. The functions that many of us have thought to be at the core of our profession are slipping from our grasp and will leave behind a mere managerial role. Nevertheless, many academic libraries will find a viable future by adopting and taking seriously the role of supporting learning. As we look at disruptive innovators in the information and learning scene, we should consider carefully …

The Federal Common Law Of Nations, Bradford R. Clark

GW Law Faculty Publications & Other Works

Courts and scholars have vigorously debated the proper role of customary international law in American courts: To what extent should it be considered federal common law, state law, or general law? The debate has reached something of an impasse, in part because various positions rely on, but also are in tension with, historical practice and constitutional structure. This Article describes the role that the law of nations actually has played throughout American history. In keeping with the original constitutional design, federal courts for much of that history enforced certain rules respecting other nations' "perfect rights" (or close analogues) under the …

Effect Of Docking And Diet Energy On Carcass Fat Characteristics In Fat-Tailed Baluchian Sheep, Ali̇ Moharrery

Contraception: Securing Feminism’S Promise, Naomi R. Cahn, June Carbone

GW Law Faculty Publications & Other Works

This paper traces the history of attempts to restrict contraception, the legal events securing widespread access to contraception and their importance to a generation of college-aged women, the short-lived nature of the consensus that produced them, and the potential of the issue to serve as a rallying point for a revitalized feminism. It explores the hypocrisy of a system that, whatever its values, makes reproductive autonomy readily available for the affluent and the sophisticated and increasingly beyond the reach of the most vulnerable. Finally, it considers the potential of contraception as a reframing device, capable of exposing the hypocrisy of …

Turkish Journal of Veterinary & Animal Sciences

To investigate the effects of supplementation of vitamin B_{12} on bovine sperm post-thaw quality, vitamin B_{12} was added at the concentrations of 1.25, 2.50, 3.75, and 5.00 mg/mL to bovine semen cryoprotective medium. The results indicated that the motility and VSL, VCL, STR, and VAP values of sperm supplemented with 2.50 mg/mL vitamin B_{12} were significantly higher than those of other concentrations (P < 0.05). No significant difference was observed for LIN and ALH values and the percentage of grade a spermatozoa between the extenders containing 2.50 mg/mL and 3.75 mg/mL vitamin B_{12} (P > 0.05). The percentages of acrosome-intact and plasma membrane-intact spermatozoa were significantly improved (P < 0.05) by supplementing with 2.50 mg/mL vitamin B_{12}. With all parameters measured, the concentration of 2.50 mg/mL vitamin B_{12} showed the best results on the quality of bovine semen in freezing-thawing. In conclusion, the addition of 2.50 mg/mL vitamin B_{12} to the extender improved the bovine frozen semen quality.

Role Of Thyroid Hormone In The Intestinal Development Of Eleutherodactylus Coqui, Srikanth Singamsetty

Electronic Theses and Dissertations

Thyroid hormone (TH) is required for the metamorphosis of the long, coiled tadpole gut in Xenopus laevis into a shorter mature adult gut. Eleutherodactylus coqui, a direct developing frog, lacks a tadpole. Its embryonic gut is a miniature adult form with a mass of yolky endodermal cells attached to the small intestine to provide nutrition. The requirement of TH for the gut development in E. coqui was tested in this study. Inhibition of TH synthesis with methimazole arrested gut development in its embryonic form. T3, the active form of TH, induced gut development. Embryos treated with methimazole failed to utilize …
