Bacterial Numbers And Activity, Microalgal Biomass And Productivity, And Meiofaunal Distribution In Sediments Naturally Contaminated With Biogenic Bromophenols, Charles C. Steward, James L. Pinckney, Yvette Piceno, Charles R. Lovell

Faculty Publications

Sediment cores were collected inside and outside of a bed of a bromophenol-producing marine polychaete, Notomastus lobatus, and examined for impact of the bromophenols on sediment microflora and meiofauna around N. lobatus burrows. No significant differences were found between microbial parameters measured inside and outside of the N. lobatus bed. Integrated 6 cm cores taken adjacent to N. lobatus burrows contained 1.2 x 10⁹ bacteria ml^-1. Cell numbers were similar at control sites within the bed, but away from burrows, and not significantly different from cell numbers (1.0 X 10⁹ cells ml^-1) at a …

Structural Evidence For Nonplanar Keto- And Planar Enol-Forms Of Oxophlorins, Mathias O. Senge, Kevin M. Smith

Faculty Publications

The first structural investigation of a zinc(II) and a free-base oxophlorin reveals considerable conformational differences between the keto- (1) and enol-form (2) of oxophlorins.

Inhomogeneous Boundary Effects In Semiconductor Quantum Wires, G. Y. Hu, R. F. O'Connell

Faculty Publications

Boundary effects play an essential role in determining the physical properties of semiconductor quantum wires. Additional features come into play when one considers inhomogeneous boundaries, i.e. wires whose widths are functions of distance along the length of the wire. The authors show that, in the adiabatic approximation (which assumes that the boundary potential fluctuation effects, or equivalently, the variations in the wire width, occur on a scale much larger than the inverse of Fermi wavelength), the boundary problem for a quantum wire is equivalent to a one-dimensional Schrodinger equation along the wire with: (i) an effective potential provided by the …

Conventionalism And Contractarianism, Noel B. Reynolds

Faculty Publications

In this paper Noel B. Reynolds’s theory of law as convention is compared to the public choice contractarian theory of James M. Buchanan. While there are numerous similarities, major differences emerge. Only conventionalism can produce legal and political authority and norms to guide the use of that authority in maintaining the rule of law. The concept of constructive unanimity is introduced to overcome the ultimate failure of contractarianism to legitimate the authority of law.

Linear Theory Of Non-Neutral Plasma Equilibrium In A Tilted Magnetic Field, Ross L. Spencer, Grant W. Hart

Faculty Publications

A linear perturbation expansion has been found that allows the rapid and accurate calculation of the response of a non-neutral plasma to a tilted magnetic field. The results of the calculation have been found to agree with previous three-dimensional equilibrium calculations, and also to agree with Keinigs' [Phys. Fluids 24, 860 (1981)] calculation of zero-frequency resonances caused by magnetic field errors. This expansion also allows the perturbed velocity to be calculated. It is speculated that this perturbed flow may be related to the enhanced radial transport in a non-neutral plasma with a tilted magnetic field.

Unobserved Ability, Efficiency Wages, And Interindustry Wage Differentials, Mckinley L. Blackburn, David Neumark

Faculty Publications

One competitive-market explanation of interindustry wage differentials that is not challenged by the persistence of these differentials is that they are due to differences across workers in unobserved ability or quality. In contrast, this paper explores the unobserved ability hypothesis by using test scores as error-ridden indicators of ability, and family background variables as instruments.This approach avoids two potential problems with using first-difference methods to remove omitted-ability bias from wage equation estimates of industry effects the exacerbation of measurement error from misclassification of industry, and selectivity with respect to industry changes. However, this approach may introduce other problems, for two …

Enhanced Bacterioplankton Production And Respiration At Intermediate Salinities In The Mississippi River Plume, Gerardo Chin-Leo, Ronald Benner

Faculty Publications

Bacterial abundance and production (thymidine and leucine incorporation) were measured along a salinity gradient from the Mississippi River (0 %₀) to the open waters of the Gulf of Mexico (36 %₀) during July-August 1990 and February 1991. Bacterial production in surface waters was maximal at intermediate salinities (15 to 30 %₀). Nutrient enrichment experiments suggested that bacterial growth near the outflow of the river was C limited whereas bacteria in plume waters of intermediate salinities were P and N limited. Rates of plankton community oxygen demand measured during winter were also maximal at intermediate …

Free Speech In Pauline Political Theology, David E. Fredrickson

Faculty Publications

Although it is generally recognized today that Paul’s faith was not a religion of subjectivity, some may nevertheless object to the notion that the apostle’s theology has a political dimension. Surely, it may be said, the sectarian communities which Paul nurtured with the stark contrasts of “outsiders” and “insiders” did not think that their task was to influence public policy in the cities of the Roman empire. While it is of course preposterous to think that the early Christians had Caesar’s ear, influencing public policy is only one way of engaging in politics.

Some Evidence On The Empirical Significance Of Credit Rationing, Allen N. Berger, Gregory F. Udell

Faculty Publications

This paper examines the credit rationing debate using detailed contract information on over one million commercial bank loans from 1977 to 1988. While commercial loan rates are "Sticky," consistent with rationing, this stickiness varies with loan contract terms in ways that are not predicted by equilibrium credit rationing theory. In addition, the proportion of new loans issued under commitment does not increase significantly when credit markets are tight, despite the fact that borrowers without commitments can be rationed whereas commitment borrowers are contractually insulated from rationing. Overall, the data suggest that equilibrium rationing is not a significant macroeconomic phenomenon.

Nuclear Dna Content Variation Within The Rosaceae, E. E. Dickson, K. Arumuganathan, Stephen Kresovich, J. J. Doyle

Faculty Publications

Nuclear DNA content has been estimated using flow cytometry for 17 species and eight cultivars of Malus and for 44 species of 29 other genera within the Rosaceae. Compared to other angiosperms, diploid genome sizes vary little within the family Rosaceae and within the genus Malus. C-values of genera within the subfamilies Spiraeoideae and Rosoideae are among the smallest of flowering plants thus far reported. In general, the Maloideae have the largest diploid genomes of the family, consistent with their higher chromosome numbers and presumed polyploid origin.

Species Of The Cretaceous Tree Fern Tempskya From Utah, William D. Tidwell, Naomi Hebbert

Faculty Publications

Nine species of the permineralized stems of Tempskya were investigated from the Lower Cretaceous Cedar Mountain and Burro Canyon Formations, and the lower Upper Cretaceous Dakota Formation in central and southeastern Utah. Tempskya jonesii, T. stichkae, and T. readii are new and are differentiated on the basis of the radial orientation of their dorsiventral stems, their internodal lengths, the lack of sclerenchyma in the inner cortex of T. jonesii, the three nearly continuous zones of sclerenchyma in the inner cortex off T. stichkae, and the completely sclerotic inner cortex of T. readii. Specimens of T. jonesii and T. minor were …

Culturally Competent Occupational Therapy In A Diversely Populated Mental Health Setting, Maria Dillard, Lynne Andonian, Olivia Flores, Lisa Anne Lai, Anne Macrae, Muhjah Shakir

Faculty Publications

Cultural sensitivity is a crucial component of health care provision, particularly in psychiatric settings. As society becomes more multicultural, it is essential for occupational therapists to continue to develop cultural competence, which is defined in this paper as an awareness of, sensitivity to, and knowledge of the meaning of culture. At San Francisco General Hospital, an innovative multicultural model consisting of special focus programs is used. The key to the success of such programs is a culturally competent professional staff.

A Descriptive Analysis And Academic Genealogy Of Major Contributors To Jtpe In The 1980s, Murrary F. Mitchell

Faculty Publications

Information about whose knowledge is accepted as important is valuable in understanding how a profession evolves. The term elders describes the individuals who control invisible networks of prestige and who determine what information is accepted for publication in professional journals. These published works stand as the foundation for the knowledge base of a discipline. The purpose of this article was to identify the elders in physical education teacher education (PETE) and to trace their academic genealogy. Elders were defined as major contributors to the Journal of Teaching in Physical Education from 1981 through 1989. The articles published by these subjects …

Liquidity Costs And Stock Price Response To Convertible Security Calls, Michael A. Mazzeo, William T. Moore

Faculty Publications

Firms' announcements to call in-the-money convertible securities for redemption essentially force their conversion into common stock, and such announcements are generally met with significant reductions in the calling firms' equity values. An explanation based on liquidity costs is advanced and tested. The explanation implies that investors who choose to sell their shares early in the conversion period bear liquidity costs by selling at reduced prices. Consistent with the explanation, the average share price decline is short-lived, lasting most of the conversion period. Thus, a component of the call announcement effect appears to be due to liquidity costs.

An Improved Choice: The Virginia Limited Liability Company, James J. Wheaton

Faculty Publications

When the General Assembly adopted the Virginia Limited Liability Company Act (the "Act")' in 1991, Virginia joined just four other states in recognizing the potential of a relatively obscure business entity, the limited liability company ("LLC"). The LLC concept has spread rapidly since the adoption of the Virginia Act early last year. Three other states enacted LLC legislation in 1991, and in just the first few months of 1992, six more states followed the trend.

[...]

Although the number of LLCs formed in Virginia since the Virginia Act took effect last July displays the willingness of Virginia attorneys to recommend …

Sound Symbolic Involvement, Janis B. Nuckolls

Faculty Publications

This article examines an iconic form of communication, sound symbolism, which has been associated with oral cultures and implicated in paradigms of primitive mentality, I argue that Lowland Ecuadorean Quechua speakers use sound symbolic iconicity to create interlocutionary involvement. A speaker's performative foregrounding of a sound symbolic form simuhtes the salient qualities of an action, event, or process, and thereby invites a listener to project into an experience. This projected involvement, in turn, points the listener to deeper kinds of imaginative, intellectual, and emotional engagement with the narrative. The argument is based on an analysis of the formal and semantic …

Ideology, Status, And The Differential Success Of Direct Parties Before The Supreme Court, Reginald S. Sheehan, William Mishler, Donald R. Songer

Faculty Publications

A substantial literature on lower federal courts and state courts suggests that the "haves" usually come out ahead in litigation because they possess superior resources for it and they reap advantages from their repeat player status. We investigate the success of 10 categories of litigants before the Warren, Burger, and Rehnquist Courts to determine whether the resources or experience of litigants has effects on Supreme Court outcomes paralleling those found in the courts below. While different categories of litigants are found to have very different rates of success, those differences do not consistently favor litigants with greater resources. A time …

An Attributional Analysis Of Resistance To Group Pressure Regarding Illicit Drug And Alcohol Consumption, Randall L. Rose, William O. Bearden, Jesse E. Teel

Faculty Publications

This article investigates the role of attributional thinking in generating resistance to pressures toward conformity in the illicit consumption of drugs and alcohol. The results of four studies regarding how conformity influences illicit drug and alcohol consumption among high school and college students are reported. In study 1 more than two-thirds of the respondents reported concern for the implications of their own dissent or compliance regarding the reactions of their peers. Study 2 demonstrated a significant relationship between high school students' attributional thinking concerning a peer group's illicit beer consumption and conformity, expressed as intentions to drink the beer. In …

Effects Of Fall Fertilizer Applications Of Mitotic Index And Bud Dormancy Of Loblolly Pine Seedlings, Hans Michael Williams, David B. South

Faculty Publications

A series of studies examined the effects of fall fertilization with diammoniwn phosphate (DAP) on mitotic index and bud donnancy [as measured by mean days to budbreak (DBB)] of two half-sib seed sources of loblolly pine. The first study tested different rates of DAP (0, 67, and 202 kg Nlha), the second study compared DAP with ammoniwnnitrate, and the third study examined the effect of different application dates (September 28, October 19, and November 9). An increase in mitotic index of unfertilized seedlings was observed during October and was due to developmental activity which follows initial budset. Differences in mitotic …

The Public Performance Right In Libraries: Is There Anything Fair About It?, James S. Heller

Faculty Publications

Two sections of the Copyright Act of 1976 permit public performances in libraries under certain circumstances. Professor Heller explains the public performance right in the context of both owners and users of copyrighted works, and proposes a fair use standard that could provide much needed guidance on the use of copyrighted videocassettes in libraries.
