Spatiotemporal Autoregressive Models Of Neighborhood Effects, R. Kelley Pace, Ronald Barry, John M. Clapp, Mauricio Rodriquez

Faculty Publications

Using 70,822 observations on housing prices from 1969 to 1991 from Fairfax County Virginia, this article demonstrates the substantial benefits obtained by modeling the spatial as well as the temporal dependence of the data. Specifically, the spatiotemporal autoregression with twelve variables reduced median absolute error by 37.35% relative to an indicator-based model with twenty-six variables. One-step ahead forecasts also document the improved performance of the proposed spatiotemporal model. In addition, the article illustrates techniques for rapidly computing the estimates and shows how to compute indices for any location.

Evaluation Of The Acoustic Doppler Velocimeter (Adv) For Turbulence Measurements, George Voulgaris, John H. Trowbridge

Faculty Publications

Accuracy of the acoustic Doppler velocimeter (ADV) is evaluated in this paper. Simultaneous measurements of open-channel flow were undertaken in a 17-m flume using an ADV and a laser Doppler velocimeter. Flow velocity records obtained by both instruments are used for estimating the true (‘‘ground truth’’) flow characteristics and the noise variances encountered during the experimental runs. The measured values are compared with estimates of the true flow characteristics and values of variance (^u92&, ^w92&) and covariance (^u9w9&) predicted by semiempirical models for open-channel flow. The analysis showed that the ADV sensor can measure mean velocity and Reynolds stress within …

Ab Initio Study Of Formazan And 3-Nitroformazan, G. Buemi, F. Zuccarello, P. Venuvanalingam, M. Ramalingam, Salai Cheettu Ammal

Faculty Publications

Formazan and 3-nitroformazan have been investigated at abinitio level (MP2/6-31G** and B3LYP/6-31G**) in all their possible conformations, for studying the various possibilities of intramolecular hydrogen bonding formation. The trans-syn-s-cis (TSSC), known also asyellowform, has been found to be the most stable conformer (at least in the gas phase) in both compounds. This particular structure is strongly stabilized by a N–H···N hydrogen bridge, which gives rise to a hexatomic chelate ring, with the possibility of a proton transfer process.This closely resembles that of malondialdehyde, previously studied, in the evolution of the …

First-Principles Determination Of Elastic Properties Of Casio3 Perovskite At Lower Mantle Pressures, Bijaya B. Karki, Jason Crain

Faculty Publications

We investigate the equation of state and elasticity of cubic CaSiO perovskite up to 140 GPa using the plane wave pseudopotential method within the local density approximation. The calculated equation of state parameters of the cubic phase are in excellent agreement with those from recent quasi-hydrostatic compression data and from all-electron linearized augmented plane wave calculations. We determine the elastic constant tensor of the mineral from the calculated stress-strain relations. The bulk modulus of CaSiO perovskite is similar to that of MgSiO perovskite, however, its shear modulus is much higher at pressures corresponding to the lower mantle. This suggests that …

Apatite Fission Track Analysis Of Sites 959 And 960 On The Transform Continental Margin Of Ghana, West Africa, P. D. Clift, A. Carter, A. J. Hurford

Faculty Publications

Four samples of sandstone from deformed Aptian-Albian sediments and their less deformed Turonian cover at Sites 959 and 960 on the Cote d'Ivoire-Ghana Marginal Ridge yielded sufficient apatite for fission track analysis. Reduced mean track length values of 12.42 ± 0.16 μm to 13.67 ± 0.11 μm indicate that measured central ages, which range from 88 ± 4 Ma to 113 ± 4 Ma, have undergone partial resetting and are therefore apparent ages. Stochastic modeling of the fission track age and length parameters indicate that the samples have a strong predepositional signal, slightly modified by minor levels of prolonged post-depositional …

Interlaboratory Comparison Of Electron Probe Microanalysis Of Glass Geochemistry, J. B. Hunt, P. D. Clift, C. Lacasse, T. L. Vallier, R. Werner

Faculty Publications

Tephrochronology commonly relies upon grain-discrete analysis of glass shards to reveal the subtle geochemical differences between tephras from past explosive volcanic eruptions. The use of electron probe microanalysis for this purpose is widely accepted by tephrochronologists. In addition, it is recognized widely that both precision and accuracy must be maximized, and that rigorous standardization procedures must be followed. In this paper, the performance of five electron microprobe centers used in the analysis of glass sharts from Leg 152 tephras is compared, using a geochemically homogeneous obsidian secondary standard. The results reveal the compatibility of most of the participatnats, supporting the …

Cognitive Agents, Michael N. Huhns, Munindar P. Singh

Faculty Publications

Several researchers have proposed using cognitive concepts as a semantic basis for agent communications (M.N. Huhns and M.P. Singh, 1997). One of the leading candidates for such a semantics is based on Arcol, the communication language used within Artimis. Interestingly, this application (not only of Arcol, but also in general) appears extremely misguided. The intentional concepts are well suited to designing agents, but are not suited to giving a basis to a public, standardizable view of communication. A challenge for using the cognitive concepts is that although they are natural in several respects and can guide implementations, full blown implementations …

How Judges View Civil Juries, Paula Hannaford-Agor, B. Michael Dann, G. Thomas Munsterman

Faculty Publications

In any given case, the judge's view of the jury may mani­fest itself as a complex and subtle mixture of respect, gratitude, con­cern, pride, impatience, and even frustration. But more revealing than what judges say about juries is what judges do to prepare jurors for their roles in civil cases. This paper explores the various indicators of judges' views of the civil jury, including the social and institutional factors and contemporary jury reform efforts that affect judges' views about the civil jury.

Toward A Practical Estate-Tax Exclusion For Family-Run Businesses: Analysis Of Section 2033a And Proposal For Reform, Eric D. Chason, Robert T. Danforth

Faculty Publications

In a previous work appearing in this Journal, the authors proposed an approach to estate and gift taxation that encourages productive behavior by the recipients of wealth. In this Article, the authors analyze, in the context of their earlier work, the new estate-tax exclusion for closely held businesses (section 2033A) created by the Taxpayer Relief Act of 1997. The authors describe the features of a practical family-run business exclusion and conclude that section 2033A, in its present form, fails as a practical exclusion. The authors catalogue those elements of section 2033A that should be retained and propose reforms of those …

An Investigation Of The Amount Of Emphasis Placed On Content And Delivery By Instructors Of Public Speaking, Paul J. Siddens Iii

Faculty Publications

A study examined how much emphasis instructors of public speaking place on content and delivery when teaching and delivering oral and written critiques. The study sought to determine whether when teaching a hybrid introduction to communication course; or public speaking course; instructors are challenged with teaching their students about issues related to the content of the speech; such as the introduction and conclusion; organization; supporting evidence; and issues related to physical and vocal delivery such as appearance; gestures; eye contact; volume; rate; and vocal variety. This was a pilot study to test the research questions; survey instrument; and methodology used …

Resurrecting The Dodo: The Unfortunate Re-Emergence Of The Puffery Defense In Private Securities Actions, Jennifer O'Hare

Faculty Publications

The conventional wisdom is that the puffery defense is inapplicable in securities regulation. However, appellate courts in almost every federal circuit have recently used the puffery defense to dismiss private securities fraud actions that were based on vague statements of corporate optimism. This Article demonstrates that the courts have misused the puffery defense and have improperly insulated companies from liability for their misrepresentations. It contends that the assumptions justifying the use of the puffery defense are not present in securities transactions and that the federal securities laws have expressly rejected the very doctrine underlying the puffery defense-caveat emptor. Arguing that …

Teaching Law Students Through Individual Learning Styles, Robin A. Boyle, Rita Dunn

Faculty Publications

(Excerpt)

Teaching can be rewarding, but it can also be frustrating when some students fail to grasp the material. Professor Robin A. Boyle of St. John’s University School of Law has been teaching Legal Research and Writing in small sections of approximately twenty to thirty students for four years. She, like many of her similarly exasperated colleagues, has repeated the same course content by using either lecture or collaborative learning, and has observed some students doing well, whereas others continued to perform poorly. Then, Dr. Rita Dunn was introduced to the law school faculty and suggested that law professors incorporate …
