Assessing Fundamental Power Differences In Exchange Networks: Iterative Gpi, Michael J. Lovaglia, John Skvoretz, Barry N. Markovsky, David Willer

Faculty Publications

Networks have been discovered for which Network Exchange Theory (NET Markovsky, Willer and Patton 1988; Lovaglia, Skvoretz, Willer and Markovsky 1995) fails to provide tenable predictions. Here we elaborate NET to create a more general method. We show not only when and where exchange networks break into simpler substructures, but propose rules to decisively classify networks and substructures as strong, weak, or equal power. In doing so, we advance general heuristics for power development in exchange networks and demonstrate the promise of an approach using reciprocal comparison of general heuristics, formal theory, and computer simulation.

Millisecond Pulsars: Detectable Sources Of Continuous Gravitational Waves?, Kimberly C.B. New, G. Chanmugam, Warren W. Johnson, Joel E. Tohline

Faculty Publications

Laboratory searches for the detection of gravitational waves have focused on the detection of burst signals emitted during a supernova explosion but have not resulted in any confirmed detections. An alternative approach has been to search for continuous wave (CW) gravitational radiation from the Crab pulsar. In this paper, we examine the possibility of detecting CW gravitational radiation from pulsars and show that nearby millisecond pulsars are generally much better candidates. We show that the minimum strain hc ∼ 10-26 that can be detected by tuning an antenna to the frequency of the millisecond pulsar PSR 1957+20, with the detector …

Faculty Publications

This paper examines the legal foundations of large-value credit transfer systems and the importance of certainty, efficiency, and fairness in funds transfer law. A case study is presented to highlight key terminology and concepts. Thereafter, five particularly noteworthy legal rules are discussed in the context of the case study: (1) a rule defining the scope of the law; (2) a rule establishing when the rights and obligations of parties to a funds transfer are triggered; (3) a receiver finality rule; (4) a rule assigning liability for interloper fraud; and (5) a money-back guarantee rule, coupled with provisions on discharge. Finally, …

Traffic Control For Automated Highway Systems: A Conceptual Framework, H.-S. Jacob Tsao

Faculty Publications

This paper proposes a conceptual framework for designing a traffic control scheme. It adopts a top-down approach to defining major design steps starting with high-level feature definition. With the desired features defined, the top-down approach then identifies and defines moves and related planning and movement functions that are required for supporting the desired features. The paper takes a systems view and identifies the safety issues regarding the movement coordination of the large number of vehicles on an Automated Highway System (AHS).

Exclusive Ρ0 Production In Deep Inelastic Electron-Proton Scattering At Hera, M. Derrick, D. Krakauer, S. Magill, D. Mikunas, B. Musgrave, J. Repond, R. Stanek, R. L. Talaga, H. Zhang, R. Ayad, G.

Faculty Publications

The exclusive production of ρ{variant}0mesons in deep inelastic electron-proton scattering has been studied using the ZEUS detector. Cross sections have been measured in the range 7 < Q2< 25 GeV2for λ*p centre of mass (c.m.) energies 40 to 130 GeV. The λ*p → ρ{variant}0p cross section exhibits a Q-(4.2±0.8-0.5+1.4)dependence and both longitudinally and transversely polarised ρ{variant}0's are observed. The λ*p → ρ{variant}0p cross section rises strongly with increasing c.m. energy, when compared with NMC data at lower energy, which cannot be explained by production through soft pomeron exchange. The data are compared with perturbative QCD calculations where the rise in the cross section reflects the increase in the gluon density at low x. © 1995.

An Integrated Framework For Learning And Reasoning, Christophe G. Giraud-Carrier, Tony R. Martinez

Faculty Publications

Learning and reasoning are both aspects of what is considered to be intelligence. Their studies within AI have been separated historically, learning being the topic of machine learning and neural networks, and reasoning falling under classical (or symbolic) AI. However, learning and reasoning are in many ways interdependent. This paper discusses the nature of some of these interdependencies and proposes a general framework called FLARE, that combines inductive learning using prior knowledge together with reasoning in a propositional setting. Several examples that test the framework are presented, including classical induction, many important reasoning protocols and two simple expert systems.

The Kinetics Of Quantal Transmitter Release From Retinal Amacrine Cells, Salvador Borges, Evanna Gleason, Michael Turelli, Martin Wilson

Faculty Publications

Exocytosis of transmitter at most synapses is a very fast process triggered by the entry of Ca2+ during an action potential. A reasonable expectation is that the fast step of exocytosis is followed by slow steps readying another vesicle for exocytosis but the identity and kinetics of these steps are presently unclear. By voltage clamping both pre- and postsynaptic neurons in an isolated pair of retinal amacrine cells, we have measured evoked synaptic currents and responses to single vesicles of transmitter (minis). From these currents, we have computed the rate of exocytosis during a sustained presynaptic depolarization. We show here …

Improving America's Health Care: Authorizing Independent Prescriptive Privileges For Advanced Practice Nurses, Mary M. Beck

Faculty Publications

Nursing and organized medicine are engaged in a heated and emotional debate over independent prescriptive privileges for advanced practice nurses. Uncontroverted data demonstrates that nurse practitioners provide high quality health care at a reduced cost, while increasing access to health care for under-served populations. It is apparent that advanced practice nurses could improve the delivery of American health care. However, organized medicine is opposed to autonomous advanced nursing practice and lobbies powerfully against it. Currently, the majority of state laws and regulations pertaining to advanced practice nursing do not promote a sound public health policy, do not contemplate liability issues …

Faculty Publications

We evaluate the ability of the BATSE spectroscopy detectors to detect the absorption lines observed by Ginga in gamma-ray burst spectra. We find that BATSE can detect the 20.6 keV line in the S1 segment of GB 870303 with a detection probability of ∼1/4 in nearly normal incident bursts, with the probability dropping off to nearly 0 at a burst angle of 50°; the lines at 19.4 and 38.8 keV in GB 880205 have a high detection probability in BATSE up to burst angles of 75°. In addition, we calculate detection probabilities for these two line types as a function …

Kings And Counselors: The Politics Of Francis Bacon's Rhetorical Theory, Christopher Holcomb

Faculty Publications

English author Francis Bacon's letters to the courtiers of King James VI before the monarch succeeded Elizabeth I reveals his concept of rhetoric as a tool for political advancement. Bacon wrote several letters to gain the king's confidence, in which he expressed his intent to portray the king in the most positive light to his subjects once he enters England and assumes the throne. The letters are remarkable in the way they suggest that Bacon can create a persona for the king through the power of rhetoric, since Bacon includes the draft of a speech which he hoped would be …

All We Really Need To Know About Teaching We Learned In Kindergarten, R. Lawrence Dessem

Faculty Publications

Being asked to talk recently about teaching to non-law school professors caused me to think about some of the successful techniques I have used or seen used in law school teaching. I was concerned, though, that these techniques might not be transferrable to other teachers in other settings. However, the more I thought about it the more I realized that the techniques we use in teaching law students are comparable to, if not identical with, techniques used by any successful teacher. These are the same techniques we all have seen utilized by our best teachers over our many years of …

Local Initiation Of Spermatogenesis In The Horse, A. J. Clemmons, D. L. Thompson, L. Johnson

Faculty Publications

Gross observation of testicular parenchyma of 1.5 to 2-yr-old horses reveals both light and dark regions. If this gross, differential shading reflects quantitative differences in the development of spermatogenesis and interstitial cell populations, the horse may prove to be a useful model for study of the paracrine relationships associated with initiation of spermatogenesis. The objective of this study was to characterize seminiferous tubules and interstitium of testes with gross, differential shading. Testes with both light and dark regions of parenchyma were obtained from horses 1.5- 2 yr old and compared to parenchyma of fetal, 2-yr old, or 5-yr-old horses. Stereology …

Measurement Of The Cross Section For The Reaction Γp → J/Ψ P With The Zeus Detector At Hera, M. Derrick, D. Krakauer, S. Magill, D. Mikunas, B. Musgrave, J. Repond, R. Stanek, R. L. Talaga, H.

Gialas, P. Giusti, G. Iacobucci, G. Laurenti, G. Levi, A. Margotti, T. Massam, R. Nania, C. Nemoz

Faculty Publications

This paper reports the cross section measurements for the process ep → e J/ψ p for Q2 < 4 GeV2 at s = 296 GeV, based on an integrated luminosity of about 0.5 pb-1, using the ZEUS detector. The J/ψ was detected in its e+e- and μ+μ- decay modes. The photoproduction cross section was measured to be 52-12+7 ± 10 nb at an average γp centre of mass energy of 67 GeV and 71-20+13±12 nb at 114 GeV. The significant rise of the cross section compared to lower energy measurements is not in agreement with VDM models, but can be described by QCD inspired models if a rise in the gluon momentum density at low x in the proton is assumed. © 1995.

Study Of D* (2010)± Production In Ep Collisions At Hera, M. Derrick, D. Krakauer, S. Magill, D. Mikunas, B. Musgrave, J. Repond, R. Stanek, R. L. Talaga, H. Zhang, R. Ayad, G. Bari, M. Basile, L.

We report the first observation of charmed mesons with the ZEUS detector at HERA using the decay channel D*+ → (D0 → K-π+)π+ (+c.c.). Clear signals in the mass difference ΔM=M(D*)-M(D0) as well as in the M(Kπ) distribution at the D0 mass are found. The ep cross section for inclusive D*± production with Q2 < 4 GeV2 in the γp centre-of-mass energy range 115 < W < 275 GeV has been determined to be (32±7-7+4) nb in the kinematic region pt(D*) ≥ 1.7 GeV, |η(D*)| < 1.5. Extrapolating outside this region, assuming a mass of the charm quark of 1.5 GeV, we estimate the ep charm cross section to be σ(ep → ccX) = (0.45 ± 0.11-0.22+0.37) μb at s=296 GeV and 〈W〉 = 198 GeV. The average γp charm cross section σ(γp → ccX) is found to be (6.3 ± 2.2-3.0+6.3) μb at 〈W〉 = 163 GeV and (16.9 ± 5.2-8.5+13.9) μb at 〈W〉 = 243 GeV. The increase of the total charm photoproduction cross section by one order of magnitude with respect to low energy data experiments is well described by QCD NLO calculations using singular gluon distributions in the proton. © 1995.

Otter: A Testbed Submersible For Robotics Research, Tim Mclain, H H. Wang, R L. Marks, S D. Fleischer, D W. Miles, G A. Sapilewski, S M. Rock, M J. Lee, R C. Burton

Faculty Publications

Untethered, unmanned submersibles (UUSs) have the potential of becoming useful tools in nuclear reactor inspection and repair and waste-site cleanup and survey, in addition to subsea exploration. Classical "hand-in-glove" control methods used currently by tethered, remotely-operated vehicles (ROVs) are unsuitable for UUS systems which have, at best, limited communications. The Stanford Aerospace Robotics Laboratory (ARL) has joined with the Monterey Bay Aquarium Research Institute (MBARI) in a program to develop new methods of controlling UUS systems.

As a part of this effort, a submersible testbed has been built to test and develop new technologies that will make UUSs useful tools …

The Sbi Program And Student Outcomes: A Study Of Business Policy Classes, Larry R. Watts, William T. Jackson

Faculty Publications

This study represents a preliminary inquiry ID to determine the value of combining SBI and Policy into a singular curriculum. A comparison of this combined formal was made wi1h the traditional Policy course. A slightly modified Job Diagnostic Survey (Hackman & Oldham, 1975) and a skills/usefulness scale (Hoffman, Fon1eno1 & Viswanathan, 1990) was administered to assess the difference between the two groups. Results suggested that the combined format met or exceeded the ou1comes of the traditional Policy course.

Small Business Transformation: The Meds Approach, Ravi S. Behara, David E. Gundersen

Faculty Publications

In today's rapidly changing business environment, small businesses must gain a deeper understanding of the future to develop strategies that will provide them with sustainable competitive advantage. The traditional approaches to strategy formulation are inadequate in an environment that is complex and dynamic. This paper investigates a "new" approach that helps small businesses "see the future." It discusses an application of the multi­ equilibrium dissipative structures (MEDS) approach to strategy formulation within the context of a small business involved in medical management software development. The dissipative systems approach can be used to evaluate the critical discontinuities that a small business …

Reading Instruction In First-Grade Classrooms: Do Basals Control Teachers?, James V. Hoffman, Sarah J. Mccarthey, Debra Bayles, Debra Price, Bonnie Elliott, Mark Dressman, Judy Abbott

Faculty Publications

This study describes first-grade teachers beliefs and practices about reading instruction. Drawing from interview and observational data, 16 teachers from four districts were placed on a continuum from skills-based to literature-based in relationship to their use of the basal. Only 2 teachers were found to rely solely on the basal, while 3 teachers enhanced the basal with literature, and 4 teachers used only literature in their reading instruction. Six teachers enhanced their basal use with additional skills and 1 teacher relied on skills only in her reading instruction. This diversity' of teaching beliefs and practices was corroborated by questionnaire data …

Stage Definition For Ahs Deployment And An Ahs Evolutionary Scenario, Jacob Tsao

Faculty Publications

Pros and cons of various mature Automated Highway Systems (AHS) have been a subject of intense study. However, such discussions are nothing but intellectual exercises unless the issue of how to evolve, in a planned and managed fashion, the current highway systems towards these mature AHS is also addressed. Since full functionality of a mature AHS cannot be realized suddenly, discrete functional steps must be identified and optimized. This paper defines an evolutionary stage towards a mature AHS as any discernible functional increment whose realization may encounter considerable difficulties requiring a significant amount of conscious effort to overcome. A good …

Multilevel Block Coded 8-Psk Modulations Using Unequal Error Protection Codes For The Rayleigh Fading Channel, Robert H. Morelos-Zaragoza, Tadeo Kamasi, Shu Lin

Faculty Publications

This paper introduces new block coded 8-PSK modulations with unequal error protection (UEP) capabilities for Rayleigh fading channels. The design of efficient block coded modulations (BCM) over 8-PSK signal sets, for the specific purpose of UEP, over Rayleigh fading channels is considered. UEP is desirable in communications systems where part of the source information is more important, or error sensitive, such as the transmission of coded speech and data broadcasting. The proposed block modulation codes are based on the multilevel construction of Imai and Hirakawa (1977). It is shown that the use of binary linear UEP (LUEP) codes as component …

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

Faculty Publications

Unequal error protection (UEP) codes find applications in broadcast channels, as well as in other digital communication systems, where messages have different degrees of importance. Binary linear UEP (LUEP) codes combined with a Gray mapped QPSK signal set are used to obtain new efficient QPSK block-modulation codes for unequal error protection. Several examples of QPSK modulation codes that have the same minimum squared Euclidean distance as the best QPSK modulation codes, of the same rate and length, are given. In the new constructions of QPSK block-modulation codes, even-length binary LUEP codes are used. Good even-length binary LUEP codes are obtained …

Wilderness Planning: A Case Study In Dispute Resolution, Michael Legg, Marlene Rebori Tull

Faculty Publications

Local landowners and environmental groups have historically disputed with the USDA National Forest Service in Texas over wilderness management issues such as wild and prescribed fire and management of the southern pine beetle (Dendroctonusfrontalis). To help diffuse polarization and open lines of communication between agency personnel and the general public, the theory of transactive planning was applied with the LAC process on two wilderness areas. Data collection consisted of: 1) participant observation; 2) issue-evaluation surveys; 3) process-evaluation surveys; and 4) exit interviews. Results indicate the planning process aids in dispute resolution by reducing antagonistic relationships and fostering public consensus in …

Phonatory And Articulatory Changes Associated With Increased Vocal Intensity In Parkinson Disease: A Case Study, Christopher Dromey, Lorraine Olson Ramig, Antonia B. Johnson

Faculty Publications

This study examined changes in voice and speech production in a patient with Parkinson disease as he increased vocal intensity following 1 month of intensive voice treatment. Phonatory function and articulatory acoustic measures were made before and after treatment as well as 6 and 12 months later. Pre- to post-treatment increases were documented in sound pressure level in sustained phonation, syllable repetition, reading, and monologue. Consistent with mechanisms of intensity change reported in normal speakers, corresponding improvements were measured in estimated subglottal pressure, maximum flow declination rate, laryngeal airway resistance, open quotient, EGGW-25, harmonic-spectral slope, and maximum vowel duration.
