Online Teaching Practices (Both Best And Worst), Michael Nelson, Bhagyavati, Gail Miles, Amber Settle, Dale Shaffer, Jake Watts, Robert P. Webber

Amber Settle

Online teaching is a whole new world for many instructors. The level of support provided varies greatly from one institution to the next. Various online platforms are available, or things can be as simple as e-mailed assignments and exams. This panel will share their online teaching experiences, discussing both what has and has not worked for them. While they do not claim to have all the answers, they are working from a good deal of experience.


Citizen Based Public Health Surveillance, Monitoring And Post-Event Assessments, Thomas Lyons Carr Iii Apr 2005

Citizen Based Public Health Surveillance, Monitoring And Post-Event Assessments, Thomas Lyons Carr Iii

Thomas Lyons (Thom) Carr III Appl.Sc., CEM

When a sudden on-set emergency or disaster affects a region or the whole country, communities and neighborhoods should plan for the possibility that emergency and other civic services will be disrupted and unavailable (District of Columbia 2003a, 2003b, 2004; Doyle 2004; Siskiyou County Public Health/NorCalBT.com 2004). The event may be severe enough that the routine public health surveillance and monitoring system will be disrupted or the system will not be able to provide data quickly enough to support state and local decisionmaking. A temporary post-disaster system should be planned for and implemented. The epidemiologist supporting the local decision makers must …


What Communities Should Do Pre-Event To Support Public Health Post-Event Assessments, Surveillance And Monitoring, Thomas Lyons Carr Iii Feb 2005

What Communities Should Do Pre-Event To Support Public Health Post-Event Assessments, Surveillance And Monitoring, Thomas Lyons Carr Iii

Thomas Lyons (Thom) Carr III Appl.Sc., CEM

[Abstract written March 2008, TLC] Under worst-case planning assumptions used by some major metropolitan areas, a Neighbor-to-Neighbor self-help program model is the primary link between citizens and the professional response personnel of the responsible government agencies.

In the Neighbor-to-Neighbor self-help program model or a Community Emergency Management Plan (CEMP) calls on the citizens in neighborhoods to identify and establish cluster emergency preparedness committees, Cluster Emergency Coordination Centers (CECC) and Community Emergency Response Teams (CERT). Missing from these plans or what is not articulated is how constant Public Health Post-Event Surveillance, Monitoring and Assessments will be done. Given the worst-case planning …


Recovering Digital Evidence From Linux Systems, Philip Craiger Jan 2005

Recovering Digital Evidence From Linux Systems, Philip Craiger

J. Philip Craiger, Ph.D.

As Linux-kernel-based operating systems proliferate there will be an inevitable increase in Linux systems that law enforcement agents must process in criminal investigations. The skills and expertise required to recover evidence from Microsoft-Windows-based systems do not necessarily translate to Linux systems. This paper discusses digital forensic procedures for recovering evidence from Linux systems. In particular, it presents methods for identifying and recovering deleted files from disk and volatile memory, identifying notable and Trojan files, finding hidden files, and finding files with renamed extensions. All the procedures are accomplished using Linux command line utilities and require no special or commercial tools.


Amyloid-Β Protofibrils Differ From Amyloid-Β Aggregates Induced In Dilute Hexafluoroisopropanol In Stability And Morphology, Michael Nichols, Melissa A. Moss, Dana K. Reed, Stephanie Cratic-Mcdaniel, Jan H. Hoh, Terrone L. Rosenberry Jan 2005

Amyloid-Β Protofibrils Differ From Amyloid-Β Aggregates Induced In Dilute Hexafluoroisopropanol In Stability And Morphology, Michael Nichols, Melissa A. Moss, Dana K. Reed, Stephanie Cratic-Mcdaniel, Jan H. Hoh, Terrone L. Rosenberry

Michael Nichols

The brains of Alzheimer’s disease (AD) patients contain large numbers of amyloid plaques that are rich in fibrils composed of 40- and 42-residue amyloid-#1; (A#1;) peptides. Several lines of evidence indicate that fibrillar A#1; and especially soluble A#1; aggregates are important in the etiology of AD. Recent reports also stress that amyloid aggregates are polymorphic and that a single polypeptide can fold into multiple amyloid conformations. Here we demonstrate that A#1;-(1–40) can form soluble aggregates with predominant #1;-structures that differ in stability and morphology. One class of aggregates involved soluble A#1; protofibrils, prepared by vigorous overnight agitation of monomeric A#1;-(1–40) …

The Acute Phase Protein Haptoglobin Is A Mammalian Extracellular Chaperone With An Action Similar To Clusterin, Justin Yerbury, Mark S Rybchyn, Simon B Easterbrook-Smith, C. Henriques, Mark Wilson Dec 2004

The Acute Phase Protein Haptoglobin Is A Mammalian Extracellular Chaperone With An Action Similar To Clusterin, Justin Yerbury, Mark S Rybchyn, Simon B Easterbrook-Smith, C. Henriques, Mark Wilson

Mark R Wilson

Haptoglobin (Hp) is an acidic glycoprotein present in most body fluids of humans and other mammals. Although the functions of Hp are not yet fully understood, the available evidence indicates that it is likely to play an important role in suppressing inflammatory responses. Some earlier work suggested that Hp might be a newly identified member of a small group of extracellular chaperones found at significant levels in human body fluids. Previously, the only well-characterized member of this group was clusterin, which shares functional similarities with the small heat-shock proteins. We report here that Hp specifically inhibited the precipitation of a …


Identifying A Source Of Financial Volatility, Douglas G. Steigerwald, Richard Vagnoni Dec 2004

How should one combine stock and option markets in models of trade and asset price volatility? We address this question, paying particular attention to the identification of parameters of interest.


Inferring Information Frequency And Quality, Douglas G. Steigerwald, John Owens Dec 2004

Inferring Information Frequency And Quality, Douglas G. Steigerwald, John Owens

Douglas G. Steigerwald

We develop a microstructure model that, in contrast to previous models, allows one to estimate the frequency and quality of private information. In addition, the model produces stationary asset price and trading volume series. We find evidence that information arrives frequently within a day and that this information is of high quality. The frequent arrival of information, while in contrast to previous microstructure model estimates, accords with nonmodel-based estimates and the related literature testing the mixture-of-distributions hypothesis. To determine if the estimates are correctly reflecting the arrival of latent information, we estimate the parameters over half-hour intervals within the day. …


The $\Alpha$ And The $\Omega$ Of Congeneric Test Theory: An Extension Of Reliability And Internal Consistency To Heterogeneous Tests, Joseph F. Lucke Dec 2004

The $\Alpha$ And The $\Omega$ Of Congeneric Test Theory: An Extension Of Reliability And Internal Consistency To Heterogeneous Tests, Joseph F. Lucke

Joseph Lucke

Psychometric theory focuses primarily on tests that are homogeneous, that measure only one attribute of a psychosocial entity. However, the complexity of psychosocial behavior often requires tests that are heterogeneous, that measure more than one attribute. In this presentation, reliability and internal consistency are extended to heterogeneous tests under the rubric of congeneric test theory. The extensions show that reliability and internal consistency have very similar properties. Reliability and internal consistency are shown to be unique up to a linear transformation. Whereas internal consistency is a lower bound to reliability in the homogeneous case, it is a strict lower bound …


Are Credit Constraints In Italy Really More Binding In The South?, Claudio Lupi Dec 2004

Are Credit Constraints In Italy Really More Binding In The South?, Claudio Lupi

Claudio Lupi

This paper is motivated by a very practical question: are there significant geographical differences in the accessibility to the credit market on the part of Italian households? The investigation is carried using robust probit model. Estimation is carried out in a Bayesian framework. The results are somewhat surprising, showing that the area where households are more likely to be credit constrained is not the South, as could be easily imagined, but rather the highly developed and industrialized North-West.
