Statistics Of The Contact Network In Frictional And Frictionless Granular Packings, Leo Silbert, Gary S. Grest, James W. Landry

Publications

Simulated granular packings with different particle friction coefficient μ are examined. The distribution of the particle-particle and particle-wall normal and tangential contact forces P(f) are computed and compared with existing experimental data. Here f≡F/F̅ is the contact force F normalized by the average value F̅ . P(f) exhibits exponential-like decay at large forces, a plateau/peak near f=1, with additional features at forces smaller than the average that depend on μ. Additional information beyond the one-point force distribution functions is provided in the form of the force-force spatial distribution function and the contact point radial distribution function. These quantities indicate that …

Mobicast: Just-In-Time Multicast For Sensor Networks Under Spatiotemporal Constraints, Qingfeng Huang, Chenyang Lu, Gruia-Catalin Roman

All Computer Science and Engineering Research

This paper is concerned with coordinated delivery of messages in sensor networks. The notion of multicast is re-examined in light of a new set of requirements that are specific to such networks. The result of this investigation is a new concept called mobicast. Mobicast entails the delivery of messages to large sets of nodes in a manner that satisfies a potentially dynamic set of spatiotemporal constraints. In order to demonstrate the feasibility of mobicast, we present a novel topology-aware protocol for sensor networks. Worst-case analysis shows that the protocol provides strong spatial and temporal delivery guarantees under a set of …

Defining A New Ethical Standard For Human In Vitro Embryos In The Context Of Stem Cell Research, Sina A. Muscati

Duke Law & Technology Review

This iBrief discusses some of the social, ethical and legal considerations surrounding the use of unimplanted, in vitro embryos in stem cell research. It proposes that a new ethical standard be elucidated for these embryos. The iBrief gives an overview of two proposals for such a standard at opposite ends of the spectrum: treating the in vitro embryo as a legal person versus treating it as mere property. It argues against both approaches. The former can have undesirable social implications including undue interference with female reproductive autonomy, while the latter would objectify potential human life and reproductive potential. The iBrief …

Isotropization In Brane Gas Cosmology, Scott Watson, Robert H. Brandenberger

Physics - All Scholarship

Brane Gas Cosmology (BGC) is an approach to unifying string theory and cosmology in which matter is described by a gas of strings and branes in a dilaton gravity background. The Universe is assumed to start out with all spatial dimensions compact and small. It has previously been shown that in this context, in the approximation of neglecting inhomogeneities and anisotropies, there is a dynamical mechanism which allows only three spatial dimensions to become large. However, previous studies do not lead to any conclusions concerning the isotropy or anisotropy of these three large spatial dimensions. Here, we generalize the equations …

Methods And Ethics In A Life History Study Of Teacher Thinking, James A. Muchmore

The Qualitative Report

During the past decade, there has been an increasing interest in the use of life history and narrative approaches to study teacher thinking and teacher development. Unlike other forms of educational research, in which relationships between researchers and participants are characterized by business-like transactions that rarely extend into the realm of the personal, life history and narrative research can involve relationships that are personal and complex. Such research can also generate massive amounts of data--in the form of field notes, interview transcripts, and other documents--which are very difficult to synthesize. This article presents some of the methodological and ethical issues …

Donatello’S David: The Putti Speak, Sally A. Struthers

Art and Art History Faculty Publications

As the first approaching life-sized, freestanding, sensuous, bronze nude since Antiquity, Donatello’s bronze David is a critical monument of the Italian Renaissance. It is also one of the most enigmatic. David is nude, but not completely unclothed, wearing a feminine-looking hat and knee-high boots. David holds a rock and a sword, while standing suggestively, on the head of Goliath. He stands in a relaxed contrapposto stance. His left hand, held to his hip, holds a stone. His right hand is resting on an oversized sword, which points downward to the helmet of Goliath, between the feet of David. As Zuraw …

An Assessment Of Seawinds On Quikscat Wind Retrieval, David Draper, David G. Long

Faculty Publications

The scatterometer ocean wind retrieval process produces several possible solutions or ambiguities at each point, requiring a separate ambiguity selection step to infer a unique wind vector field. An ambiguity selection error occurs when the selected wind vector is not the closest ambiguity to the true wind. The current ambiguity selection routine for SeaWinds is ad hoc, but performs well under most circumstances. Factors such as instrument noise and rain can also cause the estimated wind flow to deviate from the true wind. A quality assurance (QA) analysis is performed to assess the ambiguity selection effectiveness and noise level of …

The Presentation Of Paradise: Impression Management And The Contemporary Nursing Home, Jason S. Ulsperger, John Paul

The Qualitative Report

This report discusses dramaturgical perspectives, organizational impression management, and the history of the nursing home industry. Through participant observation, it uses a critical dramaturgical analysis to examine social interaction in three for-profit nursing homes. It explores how employees in these facilities create impressions of affective care in the face of negative publicity and long-term care competition. Specifically, the article examines four impression management tactics related to nursing home environments, concluding with suggestions for future research relating to organizational deviance.

Price-Matching Guarantees, Sridhar Moorthy, Ralph A. Winter

Review of Marketing Science Working Papers

Are price-matching guarantees anticompetitive? This paper examines the incentives for price-matching guarantees in markets where information about prices is costly. Under some conditions the conventional explanation of price-matching announcements as facilitating collusion finds support, and is even strengthened. But our model provides an additional explanation for the practice. A price-matching guarantee may be a credible and easily understood means of communicating to uninformed consumers that a firm is low-priced. The credibility of the signal to uninformed consumers is assured by the behaviour of informed consumers. We contrast the testable implications of our model with those of the anticompetitive theories and …

Recurrent Events Analysis In The Presence Of Time Dependent Covariates And Dependent Censoring, Maja Miloslavsky, Sunduz Keles, Mark J. Van Der Laan, Steve Butler

U.C. Berkeley Division of Biostatistics Working Paper Series

Recurrent events models have lately received a lot of attention in the literature. The majority of approaches discussed show the consistency of parameter estimates under the assumption that censoring is independent of the recurrent events process of interest conditional on the covariates included into the model. We provide an overview of available recurrent events analysis methods, and present an inverse probability of censoring weighted estimator for the regression parameters in the Andersen-Gill model that is commonly used for recurrent event analysis. This estimator remains consistent under informative censoring if the censoring mechanism is estimated consistently, and generally improves on the …

Failing Georgia: The Case Against The Ban On Social Promotion, Donald R. Livingston, Sharon M. Livingston

Education Policy Analysis Archives (EPAA)

Our analysis begins with an examination of the state of Georgia's rationale for the decision regarding social promotion that was based on the perceived views that teachers have on the issue. Research suggests, however, that teachers hold contradictory opinions concerning the use of standardized tests for high stakes decisions, such as promotion, and are not aware of the consequences most children suffer when they fail a grade. ...
