Unequal Error Protection Qpsk Modulation Codes, Robert H. Morelos-Zaragoza, Shu Lin

Faculty Publications

The authors use binary linear UEP (LUEP) codes, in combination with a QPSK signal set and Gray mapping, to obtain new efficient block QPSK modulation codes with unequal minimum squared Euclidean distances. They give several examples of codes that have the same minimum squared Euclidean distance as the best QPSK modulation codes of the same rate and length. A new suboptimal two-stage soft-decision decoding is applied to LUEP QPSK modulation codes.

Relative Kerf And Sawing Variation Values For Some Hardwood Sawing Machines, Philip Steele, Michael W. Wade, Steven H. Bullard, Philip A. Araman

Faculty Publications

Information on the conversion efficiency of sawing machines is important to those involved in the management, maintenance, and design of sawmills. Little information on the conversion characteristics of hardwood sawing machines has been available. This study, based on 266 studies of 6 machine types, provides an analysis of the machine characteristics of kerf width, within-board, between-board, and total sawing variations and wood loss per sawline. Machine conversion efficiency was found to be explained by feedworks and setworks type, and sawblade thickness and type. This analysis of machine characteristics provides information for a rational choice of sawing machines for hardwood sawmills.

A Note On After-Tax Analysis Where Capitalized Costs Are Depreciated, Steven H. Bullard, Thomas J. Straka

Faculty Publications

Forest management often requires relatively long-term and capital intensive investments. Economic analysis of timber management alternatives can therefore be an extremely important aspect of decision-making. Investment analysis techniques are prominent in forest management texts and have also been the subject of many articles in the forestry literature.

Any forestry investment analysis involves several important aspects. Topics included in reports by Gunter and Haney (1984) and Bullard et al. (1986), for example, include the treatment of inflation, income taxes, risk, and the choice of an appropriate discount rate. In this article, we focus on a very specific aspect of after-tax investment …

Relationship Between Anxiety, Self-Confidence, And Evaluation Of Coaching Behaviors, Laura J. Kenow, Jean M. Williams

Faculty Publications

Two experiments examined Smoll and Smith's (1989) model of leadership behaviors in sport. The coaching behaviors of a male head coach of a collegiate women's basketball team (n=11 players) were examined. The data supported competitive trait anxiety as an individual-difference variable that mediates athletes' perception and evaluation of coaching behaviors. There also was support for adding athletes' state cognitive anxiety, state self-confidence and perception of the coach's cognitive anxiety to the model as individual-difference variables. Athletes who scored high in trait anxiety (p<.001) and state cognitive anxiety (p<.05) and low in state self-confidence (p<.05), and athletes who perceived the coach as high in state cognitive anxiety (p<.001), evaluated coaching behavior more negatively. Game outcome may influence the effect of self-confidence in mediating athletes' perception and evaluation of coaching behaviors. Additionally, athletes perceived several specific coaching behaviors more negatively than did the coach, and athletes drastically overestimated their coach's self-reported pregame cognitive and somatic anxiety and underestimated his self-confidence. Overall, the results suggest that coaches should be more supportive and less negative with high anxious and low self-confident athletes.

Wife Abuse And The Political System: A Middle Eastern Case Study, Mary E. Hegland

Faculty Publications

Although wife abuse is common in Iran, it is a subject which has received almost no attention from scholars and little has been written on it. The purpose of this article is to examine the problem, to show the connection between wife-beating and the Iranian political system, and to raise questions for further research. The data on which this analysis is based come from my own research as well as from published sources. The two case histories of wife abuse presented exemplify social process in a political system characterized by arbitrariness and the need to dominate. The degree to which …

Rethinking Attorney Conflict Of Interest Doctrine, Kevin C. Mcmunigal

Faculty Publications

This article focuses on conflict of interest doctrine dealing with concur- rent conflict of interest issues. Its thesis is that a primary source of confusion in conflict of interest doctrine is its failure to clearly articulate and answer the central questions which lie at the heart of the subject. In essence it argues that to remedy this confusion we need to rethink attorney conflict of interest doctrine so that it focuses more clearly on articulating and answering these central questions.

Intrusion And The Investigative Reporter, Lyrissa Lidsky

Faculty Publications

Although sometimes reviled as muckrakers, investigative reporters play a valuable role in exposing societal ills and advancing reform. The success of investigative journalism is due, at least in part, to its use of novel newsgathering techniques. Yet some of these same techniques pose a threat to individual privacy. Current tort doctrine strikes an unsatisfactory balance between these competing interests. The qualified common-law privilege advocated by this Note, in contrast, would protect those newsgathering activities that promote the public welfare. Equally significantly, by sending a clear message to editors, media lawyers, and reporters about the scope of protected newsgathering activity, it …

Two-Step Polymerase Chain Reactions And Restriction Endonuclease Analyses Detect And Differentiate Ompa Dna Of Chlamydia Spp., B. Kaltenboeck, K. G. Kousoulas, J. Storz

Faculty Publications

Specific and sensitive amplification of major outer membrane protein (MOMP) gene (ompA) DNA sequences of Chlamydia species with various MOMP genotypes was achieved by a two-step polymerase chain reaction (PCR). Degenerate, inosine-containing oligonucleotide primers homologous to the 5' and 3' ends of the translated regions of all chlamydial MOMP genes were used in a PCR to amplify a DNA fragment of approximately 1,120 bp. A portion of this DNA fragment was amplified in a second genus-specific reaction that yielded a DNA fragment of approximately 930 bp. A pair of degenerate oligonucleotide primers homologous to internal sequences of the primary DNA …

Viable Embryos And Normal Calves After Nuclear Transfer Into Hoechst Stained Enucleated Demi-Oocytes Of Cows, M. E. Westhusin, M. J. Levanduski, R. Scarborough, C. R. Looney, K. R. Bondioli

Faculty Publications

Bovine oocytes were bisected, stained with Hoechst 33342 and observed under a fluorescent microscope to identify nucleated and enucleated demi-oocytes. Other oocytes were bisected but not stained, or bisected and only half of each oocyte stained, and viewed under a fluorescent microscope. The oocytes were then used for nuclear transfer by fusing them with embryonic blastomeres from a 5-6 day bovine embryo. The fusion rate and proportion developing into compact morulae or blastocysts was compared among different types of demi-oocytes. Expt 1 examined the effect of staining and indicated no effect on either fusion rate or embryonic development whether or …

Involvement Of Interleukin 2 Receptors In Conceptus-Derived Suppression Of T And B Cell Proliferation In Horses, T. L. Roth, K. L. White, D. L. Thompson, S. Rahmanian, D. W. Horohov

Faculty Publications

The mechanism by which a horse conceptus-derived immunosuppressive factor (HCS) of M(r) >100 000 inhibits lymphocyte proliferation was investigated. The factor was obtained from the culture supernatants of 20-day-old horse conceptuses; activity, identified by reduced uptake of [3H]thymidine by mitogen-stimulated lymphocytes, was greatest (P0.05). Data from a fluorescence-activated cell sorter indicated that supplementation with HCS reduced the number of T cells in phytohaemagglutinin-stimulated cultures and suppressed proliferation of T and B cells in pokeweed-mitogen-stimulated cultures compared with controls. Cell proliferation was greater (P0.05) from that of control cells. The addition of stimulated equine lymphocyte supernatant to cultures supplemented with HCS …

Coculture Of In Vitro Fertilized Bovine Embryos With Oviductal Epithelial Cells Originating From Different Stages Of The Estrous Cycle, J. K. Thibodeaux, Y. Menezo, J. D. Roussel, W. Hansel, L. L. Goodeaux, D. L. Thompson, R. A. Godke

Faculty Publications

bovine embryos derived from in vitro fertilization procedures were cocultured in vitro with oviductal cells obtained from heifers between d 4 and 6 or d 14 and 16 of the estrous cycle. In addition, proteins secreted by oviductal cells isolated between d 4 and 6 or d 14 and 16 of the cycle were monitored. Embryos (2- to 4-cell) were incubated in Tissue Culture Medium-199 with 10% fetal bovine serum with or without oviductal cells at 39°C for 10 d following in vitro insemination. There were more morulae, blastocysts, and hatched blastocysts following coculture with oviductal cells than with culture …

Creating Informal Play Opportunities: Are Parents' And Preschoolers' Initiations Related To Children's Competence With Peers?, Gary W. Ladd, Craig H. Hart

Faculty Publications

Preschoolers' social competence may depend on the frequency with which informal play activities are initiated by parents', children, and playmates. In this study, measures of children's peer relations in informal and school contexts and the frequency of parents', children's, and peers' play initiations were obtained with 83 preschool children and their families on 2 occasions. Frequent parent initiations were associated with higher levels of prosocial behavior, lower levels of nonsocial behavior and, among boys, greater peer acceptance in preschools. Children who were more initiating of informal peer contacts displayed less anxious behavior in school and were better liked by their …

Stress Begins In Kindergarten: A Look At Behavior During Standardized Testing, Pamela O. Fleege, Rosalind Charlesworth, Diane C. Burts, Craig H. Hart

Faculty Publications

Kindergarten children’s behavior before, during, and after standardized achievement testing was explored through a qualitative study in two classrooms (n = 36). Simultaneously quantitative data were collected in one of the classrooms (n = 21) before and during the testing. Data were collected through observations in the classrooms, interviews with children and teachers, and audio and video taping of the children. For the quantitative component of the study, frequencies of stress behaviors were observed using a scan sampling method. Qualitative findings indicated an increase in behaviors reported to be stress related during the testing and a decrease in those behaviors …

One-Dimensional Nash Groups, James J. Madden, Charles M. Stanton

Faculty Publications

A Lie group equipped with a compatible real algebraic structure is called a locally Nash group. We prove some general facts about locally Nash groups, then we classify the one-dimensional locally Nash groups, using a theorem of Weierstrass that characterizes the analytic functions satisfying an algebraic addition theorem. Besides the standard Nash structure on the additive group of real numbers, there are locally Nash structures on the additive reals induced by the exponential function, the sine function, and by any elliptic function that is real on ℝ. There are no other simply connected one-dimensional locally Nash groups. Any two quotients …

Extensions Of Tutte's Wheels-And-Whirls Theorem, Collette R. Coullard, James G. Oxley

Faculty Publications

Tutte's wheels-and-whirls theorem states that if M is a 3-connected matroid and, for every element e, both the deletion and the contraction of e destroy 3-connectivity, then M is a wheel or a whirl. We prove some extensions of this theorem, one of which states that if M is 3-connected and has both a wheel and a whirl minor, then either M has only seven elements or there is some element the deletion or contraction of which maintains 3-connectivity and leaves a matroid with both a wheel and a whirl minor. © 1992.

The Asymptotic Expansion Of Certain Multi-Dimensional Generalized Functions, R. Estrada, R. P. Kanwal

Faculty Publications

We apply regularization of divergent integrals in the derivation of the asymptotic expansion of certain multi-dimensional generalized functions. We further present several illustrations to demonstrate that the asymptotic development of generalized functions provides a lucid formulation of many concepts in asymptotic analysis such as the expansion of oscillatory integrals and the expansion of certain series. © 1992.

Seasonal Response Of Slash Pine (Pinus Elliottii Var. Elliottii Engelm.) Photosynthesis To Long‐Term Exposure To Ozone And Acidic Precipitation, David P. Byres, Jon D. Johnson, Thomas J. Dean

Faculty Publications

Four half‐sib families of slash pine (Pinus elliottii var. elliottii) were planted in open‐top chambers and exposed to ozone and simulated acidic precipitation (3: 7 molar ratio of nitric and sulphuric acids). The 4 ozone treatments were (1) charcoal‐filtered air, (2) unfiltered ambient air, (3) twice ambient and (4) three times ambient ozone, with treatments applied 12 h per day, 11 months per year for 28 months. Seedlings were irrigated weekly with one of three rain acidities: pH 33, 4.3 or 5.3 at a total rainfall equivalent of 133 cm per year. Photosynthetic rates were measured approximately every 10 weeks, …

Nodal Humor In Comic Narrative: A Semantic Analysis Of Two Stories By Twain And Wodehouse, Christopher Holcomb

Faculty Publications

This paper shows that a semantic theory of humor offers, despite assertions to the contrary, an adequate description of how particular instances of humor are linked to the narrative in which they appear. After Victor Raskin's script-based semantic theory of humor is summarized, and adopted as the starting point of the analysis in this paper, the humor in two short stories is described in terms of their semantic properties. In this paper, humor is said to reside not simply in jokes but in joke-like constructions, for which the term "nodal points of humor" is used. These nodes can be identified …
