Understanding Congressional Reform: Lessons From The Seventies, Rafael Gely, Asghar Zardkoohi

Faculty Publications

The purpose of this article is to examine voting behavior of representatives when faced with dual constraints (constituents back home and the leadership) as compared to one constraint (constituents back home). An ambitious goal of the study would have been to examine the effects of both sets of reforms. However, there are two reasons for not using the 1995 reforms in our empirical examinations. First, not enough time has passed to fully observe the effect of term limits on voting behavior. Second, and more importantly, the leadership, whose power it was to impose a constraint on a representative's promotional opportunities, …

Replication Banding And Sister-Chromatid Exchange Of Chromosomes Of Channel Catfish (Ictalurus Punctatus), Q. Zhang, W. R. Wolters, T. R. Tiersch

Faculty Publications

A replication banding procedure using fluorouracil (FU) and bromodeoxyuridine (BrdU) was developed for use with cultured leukocytes of channel catfish (Ictalurus punctatus). Analyzable banding patterns were produced on chromosomes stained with a fluorochrome plus Giemsa (FPG) method. The consistency of the chromosomal bands was evaluated by computer-assisted image analysis. Banding patterns of representative chromosomes including those bearing nucleolus organizer regions (NOR) were reproducible. A standard RBG-banded karyotype (R bands by BrdU and Giemsa) was established with idiograms of each chromosome. We also developed procedures to study sister- chromatid exchange (SCE) and sister-chromatid differentiation (SCD) in cultured leukocytes, without addition of …

Faculty Publications

Review by Anne Collins Smith on the H-PCAACA mailing list, June 1998.

The Metaphysics of Star Trek by Richard Hanley. New York: Basic Books, 1997. xviii + 253 pp. $18.00 (cloth), ISBN 978-0-465-09124-9.

Richard Hanley's The Metaphysics of Star Trek is an engaging examination of certain philosophical issues raised within the Star Trek universe. Its title, however, is overly broad; it would be more correctly titled, The Twentieth-Century Applied Metaphysics of Star Trek. The earliest reference in the bibliography is an article written in 1950; the next earliest, 1960. The vast majority of sources are from the 1980's and …

English Loanwords In Chicano Spanish: Characterization And Rationale, Robert N. Smead

Faculty Publications

One highly visible, often stigmatized feature of Chicano Spanish is lexical innovation due to intimate contact with English and the mainstream culture. As noted in table 1, these Anglicisms are the result of varying degrees of host language adaptation and integration and include at least three distinct types of innovations: the lexical switch, the loanword, and the calque.

Resources For Undergraduate User Interface Implementation Courses, Charles J. Welty Ms

Faculty Publications

It has been estimated that 48% of the code and 50% of the implementation time required in new applications are directly related to the user interface (Myers and Rosson, 1992). Our research shows that most undergraduate courses that consider graphical user interfaces (GUIs) have no implementation component. Most undergraduate programs (85%) that include GUI implementation are offered at the Doctoral II Carnegie classification or above. Appropriate Web and print references and other materials given in this paper will help faculty at smaller institutions offer such courses.

Failing Faith In Litigation? A Survey Of Business Lawyers' And Executives' Opinions, John M. Lande

Faculty Publications

To provide a more systematic assessment of contemporary faith in litigation, this article looks at a particular context-- business litigation--and analyzes the opinions of three groups of respondents: lawyers in private law firms who do commercial litigation (“outside counsel”), lawyers employed in business firms who do some litigation (“inside counsel”), and nonlawyer executives in business firms (“executives”). These groups have the greatest exposure to litigation in the corporate setting; furthermore, because they play powerful roles in our political, economic, and social life as well as the legal system, their opinions influence public opinion more generally.

A Novel Α-Type Carbonic Anhydrase Associated With The Thylakoid Membrane In Chlamydomonas Reinhardtii Is Required For Growth At Ambient Co2, Jan Karlsson, Adrian K. Ciarke, Zhi Yuan Chen, Stephanie Y. Hugghins, Youn Il Park, H. David Husic, James V. Moroney, Göran Samuelsson

Faculty Publications

A 29.5 kDa intracellular α-type carbonic anhydrase, designated Cah3, from the unicellular green alga Chlamydomonas reinhardtii is the first of this type discovered inside a photosynthetic eukaryote cell. We describe the cloning of a cDNA which encodes the protein. Immunoblot studies with specific antibodies raised against Cah3 demonstrate that the polypeptide is associated exclusively with the thylakoid membrane. The putative transit peptide suggests that Cah3 is directed to the thylakoid lumen, which is confirmed further by the presence of mature sized Cah3 after thermolysin treatment of intact thylakoids. Complementation of the high inorganic carbon concentration-requiring mutant, cia3, with a subcloned …

Differential Expression Of The Arabidopsis Nia1 And Nia2 Genes: Cytokinin-Induced Nitrate Reductase Activity Is Correlated With Increased Nia1 Transcription And Mrna Levels, Xiaodan Yu, Sujatha Sukumaran, László Márton

Faculty Publications

Nitrate reductase (NR) activity increased up to 14-fold in response to treatment of Arabidopsis thaliana seedlings with the cytokinin benzyladenine. NR induction was observed in seedlings germinated directly on cytokinin-containing medium, seedlings transferred to cytokinin medium, and seedlings grown in soil in which cytokinin was applied directly to the leaves. About the same level of induction was seen in both wild-type and Nia2-deletion mutants, indicating that increased NR activity is related to the expression of the minor NR gene, Nia1. The steady-state Nia1 mRNA level was increased severalfold in both wild-type and mutant seedlings after benzyladenine treatment. Transcript …

Biodegradation Of Congo Red By Phanerochaete Chrysosporium, Matthew Tatarko, John A. Bumpus

Faculty Publications

The azo dye Congo Red, was degraded extensively by the wood rotting basidiomycete, Phanerochaete chrysosporium in agitated liquid cultures and in solid malt agar cultures. Upon addition of Congo Red to agitated liquid cultures, the dye was adsorbed to the mycelial pellets in both ligninolytic and non-ligninolytic cultures followed by extensive degradation only in the ligninolytic cultures. This fungus, grown from conidiospores, readily degraded up to 718 μM (500 mg/l) Congo Red in 2.0% malt agar. Decolorization of Congo Red in malt agar plates was suppressed by the addition of supplemental nutrient nitrogen indicating that the lignin degrading system of …

Single-Head Spin Modes In Frontal Polymerization, Victor M. Ilyashenko, John A. Pojman

Faculty Publications

The single-head spin mode is the first two-dimensional pattern of self-propagating thermal reaction fronts observed after the planar front loses stability. A "hot spot" is observed to propagate around the periphery of the front. The dynamics of the single-head frontal polymerization regime were studied experimentally, and two novel results were found. The "hot spot" was measured and found to be superadiabatic. The relationship between the rotational velocity and the propagating velocity was found. Experimental data were also compared with the theoretical results based on the linear stability analysis and found to be in a reasonable agreement. (C) 1998 American institute …

Determination Of The Asymmetry Parameter And Scattering Coefficient Of Turbid Media From Spatially Resolved Reflectance Measurments, Matthew R. Jones, Yukio Yamada

Faculty Publications

We present a technique for determining the asymmetry parameter and scattering coefficient of turbid media from spatially resolved reflectance measurements. This technique will contribute to the development of medical applications in which it is necessary to predict the distribution and propagation of light in tissue. Based on Monte Carlo simulations, we derived correlations which relate the reduced scattering coefficient and the asymmetry parameter to the relative reflectance curve. Initial estimates of the optical properties are obtained from these correlations. Final values are obtained by adjusting the optical parameters and repeating the Monte Carlo simulations until the simulated reflectance pattern matches …

On Block-Coded Modulation Using Unequal Error Protection Codes Over Rayleigh-Fading Channels, Robert H. Morelos-Zaragoza, Tadao Kasami, Shu Lin, Hideki Imai

Faculty Publications

This paper considers block-coded 8-phase-shift-keying (PSK) modulations for the unequal error protection (UEP) of information transmitted over Rayleigh-fading channels. Both conventional linear block codes and linear UEP (LUEP) codes are combined with a naturally labeled 8-PSK signal set, using the multilevel construction of Imai and Hirakawa (1977). Computer simulation results are presented showing that, over Rayleigh-fading channels, it is possible to improve the coding gain for the most significant bits with the use of binary LUEP codes as constituent codes, in comparison with using conventional binary linear codes alone.

First-Year Survival And Growth Of Bareroot, Container, And Direct-Seeded Nuttall Oak Planted On Flood-Prone Agricultural Fields, Hans Michael Williams, Monica N. Craft

Faculty Publications

Container and 1-0 bare root Nuttall oak ( Quercus nuttallii, Palmer) seedlings were hand-planted, and acorns were direct- seeded, in a Sharkey soil (very fine, montmorillonitic, nonacid, thermic, Vertie Haplaquepts). The seedlings and seed were planted in January, February, March, and June, 1993. Flooding, to a depth of 2 meters, occurred on the study site from late March to late May. Seedlings planted in June were not flooded. Regardless of planting date, mean first-year survival for container seedlings was greater than 80 percent. Overall mean survival for bareroot seedlings was about 40 percent and direct-seeding survival was 30 percent. Bareroot …

Effects Of Stock Type And Fall Fertilization On Survival Of Longleaf Pine Seedlings Planted In Lignite Minespoil, Mary Anne Mcguire, Hans Michael Williams

Faculty Publications

One-year-old longleaf pine (Pinus palustris Mill.) seedlings were hand-planted in January 1996 on an east Texas minespoil site. Effects of two seedling stock types and four levels of preplanting fall fertilization on seedling survival were evaluated. Fertilizer treatments consisting of a single application of ammonium nitrate (73 kilograms per hectare N), phosphorus (81 kilograms per hectare P), diammonium phosphate (73 kilograms per hectare N, 81 kilograms per hectare P), or control (no fertilizer) were applied to bare-root and container seedlings in November 1995. Root growth potential, the ability of a seedling to initiate and elongate new roots when placed into …

Responding To The Value Imperative: Learning To Create Value In The Resolution Of Disputes, Kenneth Margolis

Faculty Publications

This article discusses another topic for clinical teachers to consider adding to their teaching agendas. In this paper, I identify the "value imperative" implicit in the attorney-client relationship and suggest that a perception by the client of high value in the relationship is necessary for its success. Briefly, I describe value in legal services as the client's perception of the ratio of benefits received from legal representation to the sacrifices necessary to obtain those benefits. The more the ratio favors benefits over sacrifices, the greater the value perceived by the client. I present a model describing value in legal services …

The Power Paradox In Muslim Women’S Majales: North-West Pakistani Mourning Rituals As Sites Of Contestation Over Religious Politics, Ethnicity, And Gender, Mary E. Hegland

Faculty Publications

During revolutions, rebellions, and movements, women are often called on to serve contradictory roles. They are asked to perform workpolitical, communicative, networking, recruiting, military, manual - that generally goes beyond the society's usual gender restrictions. At the same time, women serve as symbols of movement identity, unity, commitment, and righteous entitlement. To fit into this idealized symbolic image, individual women must fulfill often "traditional" or even exaggerated "feminine" behavioral and attitudinal requirements, such as loyalty, obedience, selflessness, sacrifice, and "proper" deportment: all in all, they are to put aside any personal aspirations and wishes for self-fulfillment and give their all …

Hypocrites And Barking Harlots: The Clinton-Lewinsky Affair And The Attack On Women, Christina E. Wells

Faculty Publications

This essay defends against the wholesale castigation of women who support the President. It reveals that such criticism is wrong and unfair. Specifically, it demonstrates that the critics have unreasonably characterized women's responses to Clinton as hypocritical or extremely naive, rather than as examples of astute political decision-making. The essay further exposes the sexism underlying the critics' arguments, revealing that stereotypes regarding (1) women's role as the keeper of morals and (2) women as non-political or non-rational beings are at the heart of much of the criticism. By reinforcing these stereotypes, the critics pose a greater danger to women than …

Analysis Of Resistance Gene-Mediated Defense Responses In Arabidopsis Thaliana Plants Carrying A Mutation In Cpr5, Jens Boch, Michelle L. Verbsky, Tara L. Robertson, John C. Larkin, Barbara N. Kunkel

Faculty Publications

In resistant plants, pathogen attack often leads to rapid activation of defense responses that limit multiplication and spread of the pathogen. To investigate the signaling mechanisms underlying this process, we carried out a screen for mutants in the signaling pathway governing resistance in Arabidopsis thaliana to the bacterial pathogen Pseudomonas syringae. This involved screening for suppressor mutations that restored resistance to a susceptible line carrying a mutation in the RPS2 resistance gene. A mutant that conferred resistance by activating defense responses in the absence of pathogens was isolated. This mutant, which carries a mutation at the CPR5 locus and was …

Effects Of Ammonium And Non-Ammonium Salt Additions On Methane Oxidation By Methylosinus Trichosporium Ob3b And Maine Forest Soils, G. M. King, S. Schnell

Faculty Publications

Additions of ammonium and non-ammonium salts inhibit atmospheric methane consumption by soil at salt concentrations that do not significantly affect the soil water potential. The response of soils to non-ammonium salts has previously raised questions about the mechanism of ammonium inhibition. Results presented here show that inhibition of methane consumption by non-ammonium salts can be explained in part by ion-exchange reactions: cations desorb ammonium, with the level of desorption varying as a function of both the cation and anion added; differential desorption results in differential inhibition levels. Differences in the extent of inhibition among ammonium salts can also be explained …

Characterization Of Root-Associated Methanotrophs From Three Freshwater Macrophytes: Pontederia Cordata, Sparganium Eurycarpum, And Sagittaria Latifolia?, A. Calhoun, G. M. King

Faculty Publications

Root-associated methanotrophic bacteria were enriched from three common aquatic macrophytes: Pontederia cordata, Sparganium eurycarpum, and Sagittaria latifolia. At least seven distinct taxa belonging to groups I and II were identified and presumptively assigned to the genera Methylosinus, Methylocystis, Methylomonas, and Methylococcus. Four of these strains appeared to be novel on the basis of partial 16S ribosomal DNA sequence analysis. The root-methanotroph association did not appear to be highly specific, since multiple methanotrophs were isolated from each of the three plant species. Group II methanotrophs were isolated most frequently; though less common, group I isolates accounted for three of the seven …

Diversity Within Streptomyces Ipomoeae Based On Inhibitory Interactions, Rep-Pcr, And Plasmid Profiles, C. A. Clark, C. Chen, N. Ward-Rainey, G. S. Pettis

Faculty Publications

Streptomyces soil rot is a destructive disease of sweetpotato (Ipomoea batatas) that causes yield loss resulting from decay of the feeder root system and reduced quality due to the presence of necrotic lesions on the storage roots. It is managed by the use of resistant cultivars, but variability of the pathogen has not been previously assessed. This study compared 36 strains of the pathogen Streptomyces ipomoeae from different locations in the United States and Japan. The strains could be separated into three groups on the basis of their ability to inhibit the growth of one another in in vitro assays. …

Isolation, Culture And Characterization Of A Primary Fibroblast Cell Line From Channel Catfish, Quiyang Zhang, Richard K. Cooper, William R. Wolters, Terrence R. Tiersch

Faculty Publications

A primary cell line (designated as CCf) derived from caudal fin tissue of channel catfish, Ictalurus punctatus, was developed using explant techniques. The cell line grew fastest in media supplied with FBS and channel catfish serum. The duplication time of the cell line under optimal conditions was ~56 h at a plating density of 1.1 x 105 cells/ml. The cell line has been propagated continuously for 25 passages (1:4 dilution per passage), cryopreserved, and recovered successfully at different passages. The cultured cells had fibroblastic morphology, and synthesized fibronectin and Type I and III collagens in the cytoplasm. The cell line …

Crossing The Line: The Political And Moral Battle Over Late-Term Abortion, Rigel C. Oliveri

Faculty Publications

This paper focuses on the political and moral debate surrounding two pieces of federal legislation which sought to criminalize a particular late term abortion technique scientifically known as "intact dilation and extraction," and popularly known as "partial birth abortion." The Congressional "Partial Birth Abortion" Bans of 1996 and 1997 inflamed the already emotionally charged contest over abortion rights. The intense lobbying and advocacy efforts put pro-choice activists in the uncomfortable position of having to defend one of the most extreme positions on the abortion-rights spectrum. The advocacy was further complicated by the fact that very few women obtain late term …
