Title: Black Holes Can Dance
Speaker: Sethanne
Howard
Black holes can dance and yet they have no hair. Dr. Howard will
discuss these and other interesting facts about the fascinating field of black
holes. There will be a quick trip to a black hole and several interesting
simulations of black hole behavior to show. If you ever wondered what that
black hole "event horizon" means you are not alone. Such properties of black
holes will be discussed.

Title: Conceptions of Complexity and Implications for Economics
Speaker: Stuart Umpleby, The George Washington University, Washington, DC
Most of science consists of results obtained with rather simple
descriptions small numbers of variables and often linear relations among
them. In recent years there has been growing interest in complex systems. There
are at least three definitions of complex systems: 1) systems with large
numbers of variables and many relationships among them; 2) systems composed of
numerous autonomous (usually preprogrammed) actors/ algorithms which interact,
producing often unexpected results (i.e., emergence); 3) systems involving
knowing participants acting in systems in which they have an interest in the
outcome. The term "complexity" can be used to refer to the first category. The
terms "self-organizing systems" or "complex adaptive systems" are used for the
second category. "Reflexive systems" refers to the third category. To
illustrate these three categories and how they influence the creation of
theories, three conceptions of economic theory will be described.
Title: Experiments in Reflexive Inquiry
Speaker: Kent Myers,
Associate, Booz Allen Hamilton
We review four iterations of Virtual
Systemic Inquiry (VSI), a method that embraces reflexivity. VSI exploits the
free cognitive surplus available through the web and otherwise starts with no
rules, just cybernetic principles: openness, variety, interaction, and an
orientation to the common good. Conventional methods, while better in many
ways, actually don't score highly against these criteria. We review and
contrast four VSI projects in which procedures were varied and products ranged
from a published book to a non-convergent, perpetual conversation. We discuss
failures and successes and suggest directions for improvement. We conclude by
exploring in what ways this method is reflexive and the advantages this can
bring to social inquiry and specifically to public intelligence, even as it
breaks all the rules.
Title: Conceptual Difficulties and Pragmatic Responses to Research &
Development Contracting
Speaker: Steven C. Stryker, Professional Consultant
and Trainer, Stryker Associates
Trying to define what is the true nature of
Research and Development (R&D) has several different constructs. Given the
need to buy R&D, one is faced with which understanding will be employed to
appropriately and effectively obtain the conceptualized results. The paper will
evaluate acquisition strategies that are applicable across various R&D
domains. Implications for buying and doing and future R&D are shown.

Title: Inventive Thought: How to stimulate it and what to do about it
when it strikes
Speaker: Mark A. Holland, Professor and Chair, Dept. of
Biological Sciences Salisbury University
Many of us are raised in an
environment of basic research. Applied science is otuside the realm of our
every day experience. However, applied thinking can be a stimulating challenge
and an enjoyable and profitable addendum to basic bench work. In this
presentation, we will consider ways to stimulate innovative and inventive
thinking, discuss some practical guidelines for the protection of intellectual
property and consider some of the issue involved in taking science from the lab
into the marketplace. This presentation will be aimed especially toward a
student audience.

Title: Systematic overview of the North American Paper Daisies
(Asteraceae: Gnaphalieae) and the use of Lucid as an identification tool
Speaker: Christopher F. Puttock1 1Smithsonian Institution, Department of
Botany, National Museum of Natural History
The Gnaphalieae are a tribe of
about 180 genera and 1240 species (10% of the Asteraceae), with the greatest
diversity in Africa and Australia where the involucral bracts of many taxa have
long brightly-colored stiff lamina. The 2006 Flora of North America North of
Mexico treatment of the Gnaphalieae has 19 genera and 111 species. Three
authors were engaged for the preparation of these taxa (Bayer - Antennaria;
Morefield - Filagininae; Nesom - the rest). Each author has different species
and generic concepts, and placed emphasis on different characters in their
descriptions. Building an electronic key to these species has highlighted the
difficulties that an editor has in bringing a standard terminology to a
treatment, even within such a small group of taxa. The resulting process has
filled in many missing character-states, resulting in more comprehensive
descriptions of these taxa. These new morphological data have been assembled
into the Lucid software to produce the first electronic key to the North
American species of the tribe.

Leptochloa (including Diplachne) s.l. is a diverse assemblage of C4
(NAD-ME and PCK) grasses with approximately 32 annual or perennial species.
Evolutionary relationships and a modern classification of Leptochloa species
based on the study of molecular characters have only been superficially
investigated in four species. Our goals are to reconstruct the evolutionary
history of Leptochloa s.l. with molecular data and broad taxon sampling. We
conducted a phylogenetic analysis of 130 mostly Chloridoideae species, of which
22 are placed in Leptochloa, using five plastid (rpL32-trn-L, ndhA intron,
rps16 intron, rps16-trnK, and ccsA) and the nuclear ITS 1 and 2 (ribosomal
internal transcribed spacer regions) to infer evolutionary relationships and
revise the classification. Leptochloa s.l. is polyphyletic and we find strong
support for five lineages. Embedded within the Leptochloa s.s. clade are two
species of Trichloris and embedded in Dinebra are Drake-brockmania and 19
species of Leptochloa. Our molecular results support the dissolution of
Leptochloa s.l. into the following five genera: Dinebra with 23 species,
Diplachne with two species, Disakisperma with three species, Leptochloa s.s.
with five species, and a new genus, Trigonochloa with two species.
Title: Bringing taxonomic and biodiversity information to the global
scientific community.
Speaker: Robin Everly, Science Librarian in Botany
and Horticulture, Smithsonian Institution Libraries, National Museum of Natural
History
Until recently, historical scientific print information was found
mostly in libraries in North America and Europe. Several digitization projects
are currently underway to bring the literature full text to the rest of the
world. More importantly, this information is now becoming more easily available
to the developing world where much of the biodiversity of plants and animals
resides. This presentation will discuss ongoing projects such as the
Biodiversity Heritage Library (BHL) and several plant and zoological
information databases. Currently, the core literature collection in BHL is
natural history publications in the public domain and primarily taxonomic in
its scope. Also, open access journals and how they are providing worldwide
access to information to the scientific community will be discussed.
Capital Area Food Protection Association
Title: Produce Safety Research at ARS: From Farm to Fork
Speaker:
Dr. Manan Sharma, USDA, Beltsville, MD
Over the last 20 years, there have
been high profile outbreaks associated with the consumption of contaminated
produce (sprouts, leafy greens, tomatoes, cantaloupes) which have sickened and
killed hundreds of people. Produce commodities grown in agricultural fields
have multiple opportunities to be contaminated with microbial pathogens on the
way to consumers' plates, hence the "Farm to Fork" paradigm. Scientists at the
United Stated Department of Agriculture, Agricultural Research Service
(USDA-ARS) work to investigate mechanisms how bacteria, such as pathogenic E.
coli, Salmonella and Listeria monocytogenes, contaminate produce commodities.
These strategies include investigating novel decontamination protocols for
irrigation water, examining the length of persistence of these bacterial
pathogens on leafy surfaces of plants, routes of contamination of leafy greens,
and if current recommendations are sufficient to provide protection against
produce contamination. ARS Scientists do the "dirty" work in fields, with soil,
manure and water and bacteria. Outside, inside we traverse the fields to
find where the bacteria are. Sometimes you need boots, sometimes you carry a
microscope - very frequently you need both to comprehensively address produce
safety issues!
Title: Foodborne Outbreak Investigations-What Happens Behind the Scenes
Speaker: Keith Lampel, FDA
According to the new data from the Centers
for Disease Control and Prevention, approximately 49 million people will become
sick due to foodborne pathogens. Ensuring that consumers have a safe food
supply is one of the missions of the Food and Drug Administration as well as
other US regulatory agencies. When food-related outbreaks do occur, the
identity of the source becomes critical to prevent further spread of the
contaminated food and to reduce the potential number of people who may become
ill. The complexities of foodborne outbreaks are myriad in many external
factors such as the food matrix, the number of potential ingredients, whether
the food was imported or grown in the US, and what methods are available to
identify the putative pathogen. Overall, foodborne outbreak investigations
encompass the work of epidemiologists, microbiologists and an effective
communication system to respond to these events.
Title: Technology at Hand in Outbreak Investigations
Speaker: George
Wilson, PathSensors, Inc.
Foodborne outbreak investigations require a rapid
response in the detection and identification of microbial pathogens from a wide
variety of food matrices. The critical nature to quickly identify the source of
the adulterant lies in the cooperative action by the food industry and
regulatory agencies to ensure appropriate measures are taken to contain, and
control the spread of foodborne pathogen to minimize the personal toll to the
US consumer. The evolution of technology used in analytical laboratories has
taken us from the laborious and time consuming "shake and plate" approach
through the advent of molecular biology based methods and perhaps in the near
future become the basis of novel techniques that can in minutes identify the
microbial pathogen in food.

Title: Online Introductory Physics Labs: Status and Methods
Speaker:
Ann M. Reagan,College of Southern Maryland, La Plata, MD
Nearly 400 US
colleges and universities offering undergraduate introductory physics courses
were surveyed to determine the extent to which introductory physics instruction
is currently available in a fully online format. A second survey, targeting
those institutions offering online introductory physics courses, identified
current approaches to and plans for making the corresponding physics laboratory
course components available online. A single approach towards online
laboratories was selected, and a set of experiments was developed based on
program goals for technical rigor, student engagement, cost, and suitability
for deployment in an online environment. Preliminary results and "lessons
learned" from the deployment of these experiments in an online instructional
format are discussed, as well as recommended next steps for the development of
a research-based online physics laboratory curriculum.
Title: Experiments in Inductive Magnetic Levitation
Speakers: Robert
Argus, Jeffrey Mickle, Jonathan Mills, Omar Moran, Tony Nguyen, Zaeema
ZafarNorthern Virginia Community College, Annandale, VA
The aim of this
paper was to investigate experimentally the velocity dependence of the
repulsive force between a cart containing a magnet (a Nd Halbach array) and a
metallic track, or a system of induction coils, as a laboratory model of the
inductionally levitating magnetic cart. This system is too complicated to be
treated mathematically, and so we used an experimental trial-and-error method,
investigating several configurations and using existing theoretical estimates.
We will present the current results and the ideas for the future improvement of
our design.
Title: A Physical Model for a Toroidal Dipole Moment
Speakers:
Kiarash Akhlagi, Duke Forsyth, Tanya Saha , Vikram Sarkhel, Benjamin Short
Northern Virginia Community College, Annandale, VA
There are three families
of electromagnetic multipoles: well-known electric and magnetic, and less known
toroidal multipoles. While the magnetic dipole moment m is physically
represented by a loop of current, the dipole toroidal moment t (called
sometimes an anapole) is modeled by a toroidal solenoid, or by a magnetic ring
magnetized along the circumferential axis. While magnetic dipole m interacts
with the static magnetic field B, the toroidal dipole t interacts with the curl
of B, which can be produced by the current density flowing through the toroid
it or by a variable electric field in it. The purpose of this paper is to
describe our experiments with this electromagnetic device essentially a
magnet without magnetic poles, and our measurements of its strength as compared
with the theoretical estimates. The experiment itself may constitute one of the
few available electromagnetic experiments to demonstrate directly the existence
of the Maxwell term in the Ampere's Law. Frictionless Bearings in a Model of
Inductive Magnetic Levitation Northern Virginia Community College, Annandale,
VA Ramsey Benhusen, Brad Bynum, Doug Goncz, Faraz Hameed, Erin Jennings, Ryan
Thompson We are conducting a series of experiments on levitation of a rotating
circular Halbach array of Nd magnets over an inductive base made of metal plate
or coils. We build the array from specifically magnetized Nd segments
concentrating the sinusoidally variable magnetic field at the bottom of the
ring. The ring is rotated above an inductive base, while being able to move
vertically along the system of guiding rods in order to observe the levitation
force on the ring against the force of gravity. The repulsion is provided by
the eddy currents induced in the base plate according to the Faraday's Law.

Title: A New Fuel Gauge
Speakers: Nick Willard, Wei He, Mingzhi
Dong, Dr. Michael Osterman, Prof. Michael Pecht
After cost, the biggest
practical concern for the adoption of electric vehicles (EVs) into mainstream
usage is the problem of range anxiety. This is the fear that an EV user
experiences due to the inaccuracies of the battery fuel gauge. With EVs
currently in the beginning phases of market adaptation, range anxiety is
amplified by the lack of electric vehicle charging infrastructure. A
miscalculation of an EV's remaining driving time can leave a user stranded with
no charging station in sight. Unlike a traditional fuel gauge meter which
simply measures the level of liquid fuel in a gas tank, determining the
remaining charge in a battery is a much more complex problem. Physically, the
charge in a battery is dependent on the reactant concentration inside each
electrode but because ion transport is a micro-scale phenomenon which occurs
inside of a closed battery system, this quantity cannot be measured directly.
Instead the battery's state of charge (SOC) is inferred by measuring the
battery's voltage potential and relating it back to SOC or by counting coulombs
and comparing the charge released by the battery to the total amount of charge
the battery initially had stored. The problem with these methods is that a
battery's measured voltage is always influenced by an overpotential which is
highly dependent on factors such as the discharge current rate and external
temperature. Similarly, the battery's charge capacity is influenced by current
rate, temperature, and cell aging. In order to provide the best estimate of a
battery's SOC, self-adaptive techniques are described which account for
real-world variability on battery discharge loads can so that remaining driving
time estimations in EVs can adapt to different driving profiles and conditions.
Title: Prognostics of Insulated Gate Bipolar Transistor (IGBT) under
Power Cycling
Speaker: Edwin Sutrisno, Graduate Research Assistant, Center
for Advanced Life Cycle Engineering (CALCE), University of Maryland, College
Park
Insulated Gate Bipolar Transistor (IGBT) is a power electronic
transistor used in medium to high power applications such as hybrid cars,
railway traction motors, switch mode power supplies, and wind turbines. As more
and more IGBTs are finding their ways into large and complex systems, the
ability to detect and predict failures in IGBTs can provide a key advantage in
driving down cost of maintenance while improving system availability and
safety. This study begins with understanding the critical failure mechanisms of
IGBTs under power cycling conditions. Aging tests are performed to collect
healthy-to-failure data of IGBT samples in the form of currents, voltages,
temperatures, and switching speeds. Several critical parameters are extracted
and analyzed in a k-Nearest Neighbor (kNN) fault detection algorithm. The
proposed kNN algorithm successfully detects faults just before the IGBTs enter
an accelerated degradation stage toward latchup. A method to predict the
remaining useful life of the IGB:T is also discussed.
Title: Geotherman Energy
Speaker: Nancy Landreville
The White
House report, "A New Generation of American Innovation," dated April 2004 and
the Department of Energy (DOE) report, "DOE Geothermal Technologies Program,
Multi-Year Program Plan 2006-2011," dated August 31, 2005 discuss the
remarkable capabilities of geothermal energy as an alternative energy resource.
The implementation of this technology will drastically reduce cost and create a
sustainable renewable energy that is never depleted. The Department of Defense
(DOD) applies geothermal resources on military bases at the Navy Air Weapons
Station in California. This resource has been successfully implemented for a
number of DoD sites. Geothermal energy is popular in desert areas, western US
states, and African and Asia countries with unusually high temperatures.
Sources of geothermal energy are not contingent upon the existence of volcanic
rock or geysers. Enhanced geothermal systems (EGS) are available for industry
and home use providing not only electricity through conversion but also have
the capability of providing water to a building and/or home.
Electrically-powered cooling units could enhance the comfort of a deployed
workforce, for example, in any environment by drilling a geothermal well and
acquiring access to the natural resource. Hospital units that require air
condition units, for example, would have continual access to geothermal energy
for cooling. These units could be continually sustained without loss of power.
This remarkable and natural resource has the capability of replacing or
supplementing our depleting oil resource. The Geothermal Technologies Program
is a partnership with industry and the government to use geothermal energy in
an economic and competitive manner to enhance our energy supply. Geothermal
energy production provides a means for generating electricity, heat, and/or
direct application capability for crop drying, heating, or heat pumps for
buildings. It is an effort to provide reliable, cost competitive, and
sustainable energy (not add to air pollution) thus reducing inefficient energy
use overall and reducing greenhouse gases by using an alternative energy
source. It is also independent of fuel price changes and dependencies on oil
from foreign governments. Customer value management requires identification of
the best customer base offering the greatest return on investment. Advantage is
sustained when sources are widened and upgraded. Innovations shift competitive
advantage when competitors do not respond to new innovations in anticipating
customer needs. The value chain however, provides a tool for understanding the
sources of cost advantage. Gaining cost advantage requires optimizing the
linkage among activities. In the innovation stage, the full diamond is in place
in a wide range of industries such as geothermal technology while biotechnology
is advancing innovations in microchips. The subsequent stage is identifying and
categorizing your customers. Then, evaluate and define your product after
ranking it according to market value. In summation, true innovation will always
test the limits and success has an eye to the future with integration of
knowledge and ideas.
Title: Identification of Failure in Mechanical Equipment from System
Level Signals in a Wind Turbine
Speakers: Ranjith Kumar, Michael H.Azarian
and Michael G.Pecht, Center for Advanced Life Cycle Engineering, University of
Maryland, College Park, MD
Complex engineering systems, such as a wind
turbine, consist of a lot of components such as, the gearbox, bearings,
generator, and rotor blades. Condition monitoring and prognostics of such
complex systems often requires a multitude of sensors monitoring the different
components, since each component has several relevant characteristics or
degrees of freedom that can best describe its health condition. The monitoring
of all these parameters for the detection of faults can be complex, not least
because of the cost and reliability of the sensors themselves. In this paper,
we present a component-level diagnostic method using system-level signals. A
system-level dynamic model is of the system is generated using MATLAB Simulink.
Fault simulation is carried out in this model, to study the effect of faults in
mechanical components on system-level signals such as electrical torque of the
generator of the wind turbine. In this process, the sensitivity of system-level
sensor signals with respect to the model parameters is also estimated.
Detectability of a particular component failure and redundancy in detected
signals are discussed. In the numerical example, failure scenarios of single
and multiple components are also tested.
Title: The Global Alliance for Outer Space Development, Inc.
Speaker: Dr. Edythe E. Weeks, Esq., Webster University, St. Louis, MO
Outer space is at the brink of development. Meanwhile, the US economy is
troubled. Opportunities likely to emerge as outer space is developed holds the
key for economic prosperity, job creation, workforce development and retraining
and the creation of networks and internship and employment opportunities for
students as well of members of the global general public. This paper will
discuss and explore new opportunities to make innovation applications for solar
and renewable energy, solar space settlements, spaceships powered by renewable
energy concepts and green technology, along with strategies for protecting the
air, water and outer space environment as space travel become increasingly
common, will provide avenues for participation for a broad diverse range of
people, by providing inspiration and motivation to pursue knowledge in creative
scientific fields. The paper will also discuss how these activities can be
linked to achieving key goals set forth in the NASA Authorization Act of 2010
such as Section 202(b) which discusses the restructuring of the exploration
program so that it "allows the systems developed under the restructured
exploration program to serve as potential test beds for the demonstration of
key enabling exploration technologies and operational capabilities", as set
forth in paragraph 8, and paragraph 9, which indicate that the manner "prepares
for and enables human missions to a variety of destinations in the inner solar
system, including cislunar space, the Moon, Lagrangian points, near-Earth
objects, and ultimately Mars and its moons". The paper will propose that
creating collaborative networks, and forging alliances between business
entities, entrepreneurs, institutions, governmental entities, universities,
K-12 institutions, students and individuals may provide the solution that will
enable these key issue areas.
Title: FS-TIGBT Degradation by Power Cycling under Inductive Load with
Different Switching Frequencies, Duty Cycles and Temperature Swings
Speakers: Qingguo Fan, Diganta Das, and Michael Pecht, Center for Advanced
Life Cycle Engineering (CALCE), University of Maryland, College Park, MD
Field Stop Trench Insulated Gate Bipolar Transistor (FS-TIGBT) is a power
switching device often under inductive load, such as the switches in motor
drives and power converters. In its application circuitry, the parasitic/stray
inductance causes an inductive voltage spike across an FS-TIGBT each time the
device turns off because of the abrupt current drop. This study included tests
to accelerate the degradation of FS-TIGBTs under repetitive inductive voltage
spike with different switching frequency, duty cycle and temperature swings. In
the experiments, wire bond fatigue, solder layer fatigue and aluminum
reconstruction were encountered during ageing process before latch-up or second
breakdown failure of the devices. Our analysis found that different temperature
swings cause different ageing behaviors. An increase of duty cycle results in a
decrease of a FS-TIGBT's lifetime. An increase of switching frequency results
in an increase of a FS-TIGBT's. Switching frequency acts together with
repetitive inductive voltage to affect wire bond degradation.
Title: Microwave Plasma CVD Reactor for Single Crystal Diamond
Deposition
Speakers: K. W. Hemawan, C. S. Yan. Q. Liang, Y. Meng, S.
Krasnicki, J. Lai, T. Yu, H. Shu, H. K. Mao, and R. J. Hemley, Geophysical
Laboratory, Carnegie Institution of Washington
Diamond has unique
mechanical, thermal, optical, and electrical properties compared to other
materials. These extra ordinary properties make diamond a very promising
material for a broad range of scientific and technological applications. We
have developed an improved microwave plasma chemical vapor deposition (MPCVD)
reactor that can produce high growth rates and high quality single crystal
diamond. In particular, MPCVD reactor with evenly distributed plasma that
allows larger deposition areas, higher absorbed power density, and uniform
substrate temperature distribution across the substrates during diamond
synthesis. Numerical modeling of the MPCVD reactor such as profile distribution
of electric field, electron density and electron temperature as a function of
microwave input power and operating pressure is presented. Spatially resolved
in-situ optical emission spectroscopy (OES) is utilized to investigate the
plasma emission such as excited species intensities, gas temperature and ratios
of radical species that influence diamond growth. The correlation between the
plasma properties versus operating parameters that affect diamond growth is
analyzed. Synthesized multi carats, near colorless optical quality single
crystal diamond are also presented.
Title: Prognostics for Cell Balancing of Lithium-ion Batteries
Speakers: Mingzhi Dong, Nicholas Williard, Wei He, Dr. Michael Osterman,
Prof. Michael Pecht
Rechargeable batteries are widely used in many
applications, such as consumer electronics and electric vehicles (EVs). The
Lithium-ion battery has higher cell voltage, energy density, no memory effect,
and is the most promising battery for EVs. When a collection of cells are
connected in series, state of charge (SOC) of different cells may deviate from
each other, known as cell imbalance. To avoid over-charge and over-discharge
and maximize both the usable capacity and the life of the battery, many cell
balancing methods have been developed. Prognostic and health management (PHM)
can be implemented into cell balancing in two aspects. First, prognostics can
help predict cell imbalance enabling the predictive control of cell balancing
process. Accurate prediction of cell imbalance can make cell balancing process
more efficient. Second, cell balancing methods can be improved by accurate SOC
estimation of individual cells in a battery pack. SOC estimation has been
facing difficulty due to the complexity and uncertainty of battery system.
Implementation of PHM techniques can benefit the accuracy of SOC estimation by
in-situ monitoring battery parameters, leading to more effective battery
management systems
Title: Integrating decision making techniques into argument maps in the
context of e-Rulemaking
Speaker: Keith Walker
Governments are striving
to take advantage of the Internet to engage citizens in policy deliberation
(e-Participation/e-Rulemaking), and argument mapping is one technique that has
potential for this purpose. Argument mapping is a visual notation in which
information is presented as linked nodes that are questions, ideas, pros and
cons. One drawback of argument maps is that they provide little support for
decision making. My work seeks to enhance the usability of argument maps for
decision making, and the presentation will show a design for integrating a
decision making technique with argument maps. The context of the work is
federal rulemaking for the Affordable Care Act, specifically the creation of
health insurance CO-OPs. An argument map was created from the rule and public
comments. A decision making technique appropriate to the situation will be
described, as well as a design for integrating it into the argument map
Title: State of Charge Estimation for Electric Vehicles Using Unscented
Kalman Filtering
Speakers: Wei He, Nicholas Williard, Mingzhi Dong, Michael
Osterman, and Michael Pecht, Center for Advanced Life Cycle Engineering,
University of Maryland, College Park, MD
With increasing concerns on the
global warming and fossil fuel depletion, the automobile industry is facing a
landmark transition in the next few years. Electric vehicles (EVs), which are
powered by lithium-ion batteries, are going to penetrate into the automobile
market. However, there are still some challenges for EVs that remains to be
solved. The most notable one is the state of charge (SOC) estimation for
optimal control and management of EV batteries. This paper propose a battery
SOC estimation method using unscented Kalman filtering based on Coulomb
Counting and open circuit voltage. The battery discharge data based on federal
driving schedule are used to validate the proposed method. It shows that the
proposed method can estimate the battery SOC with an error smaller than 4%.
Title: Simulation-based Military Training: An Engineering Approach to
Better Addressing Competing Environmental, Fiscal, and Security Concerns
Speaker: Jason E. Summers, Applied Research in Acoustics LLC
Governments and militaries have long recognized that armed forces must
engage in training in order to develop and maintain the proficiency necessary
to effectually carry out those legitimate duties with which they are entrusted
by their nation. This is made particularly salient by the increasing demands
placed on individual members of the armed forces because of reduced staffing
and increased task complexity. Yet training comes at a significant financial
cost: roughly one third of the total defense budget in fiscal year 2012 is
devoted to training. Moreover, military operations directly impact the
environments in which they are carried out, while also burning significant
quantities of fossil fuels. Broad societal, government-wide, and Department of
Defense commitments to improved environmental management together with fiscal
austerity measures enacted in response to the financial crisis will
increasingly bound the scope of training operations, potentially limiting their
utility. Often the challenges these bounds bring are approached only as a
zero-sum problem of balancing interests, as exemplified by the 2008 Supreme
Court trial over sonar training by the U.S. Navy. However, scientific advances
have improved the understanding of physical phenomena and, together with
innovations in modeling

Title: The Need to Integrate Human Aspect in a Process Improvement
Endeavor
Speakers: Anil R. Kumar and Anand Subramanian JFAssociates, Inc
The goal of all business enterprises is to increase value for its
shareholders. In order to do this, companies seek to improve their existing
processes to make them more efficient, improve productivity, reduce costs, and
eliminate or decrease the frequency and severity of work related injuries. All
of these actions result in monetary savings and contribute to a positive
corporate triple bottom line (profitability, quality, and safety). The
development of a standardized methodology with which to investigate improvement
opportunities is not a new concept. Throughout history, a number of techniques
have been developed that begin with management involvement and attempt to
provide standardized processes to solve issues. Currently, a number of
techniques can be applied to situations to achieve this goal, including process
improvement, lean, six-sigma, supply chain, and ergonomics; however, all of
these techniques are seldom incorporated into a comprehensive approach to
improve process and efficiency. The development of a standardized comprehensive
process improvement methodology allows a holistic look at how work is performed
so that opportunities can be determined, recommendations can be identified, and
changes can be made. When key personnel are involved in process improvement
(such as managers, employees, and other key stakeholders), they can
collectively focus on eliminating inefficiencies and waste (e.g. money, people,
materials, time, and opportunities). The result is a new process that is
cheaper, faster, safer, and more efficient than the current. Process
improvement is an umbrella term for a number of techniques that aim to make
processes more efficient including six-sigma, lean, agile management,
re-engineering, total quality management (TQM), just in time (JIT), and process
excellence. One of the key components that is missing from most process
improvement techniques is the consideration of the human system taking into
account the human capabilities and contributions including the cognitive,
physical, and physiological capacities. This paper details the results of a
case study wherein the human system was considered during the project
execution. The case study demonstrates that when HPI concepts are applied in
concert with each other through teamwork and data analysis, the whole becomes
greater than the sum of its parts.
Title: Rating Emmployee Performance for Non-Manufacturing Jobs Using
Work Measurement Techniques
Speakers: Anand Subramanian and Anil Kumar,
JFAssociates, Inc.
Traditionally, organizations in the manufacturing area
and also those in the service area such as hospitality, infrastructure,
security, logistics, consumer service and retail functions have a large
component of their work force performing tasks that require some form of direct
or indirect supervision. For such jobs in the manufacturing industry
remuneration and incentives are mostly based on output and productivity
achieved by the employee and is also referred to as piece-rate. In the service
industry such jobs are sometimes remunerated based on the output achieved by
the employee and the incentives are in the form of additional pay or time
credits. In the manufacturing industry, the incentive levels are set by time
standards derived using traditional work measurement techniques. Rating is a
critical component of the establishing a time standard whereby an individual
employee's performance is directly (based on the rater's perception) compared
against the average employee's pace, skill, and/or effort. Though
controversial, practiced rating practitioners are remarkably consistent. The
rating practitioners train regularly and update skills to maintain a common
perception of standard rating through rating 'clinics'. In this presentation,
we will discuss the various rating techniques and how the traditional rating
technique is modified to be used while rating non-manufacturing jobs. A case
study with a methodology to rate of tasks from the service industry will be
discussed and results presented.
Title: Role of Industrial Engineer in Improving Quality of Life
Speakers: Anil R. Kumar and Anand Subramanian, JFAssociates, Inc.
Industrial Engineers are typically associated with process improvement
projects that involve cost reduction, efficiency improvement and time
reduction. Another aspect of an industrial engineer's endeavor is to improve
the quality of life while designing the workplace/system. The field of
industrial ergonomics is concerned with the design of the workplace to
accommodate the human capacity in order to increase productivity and decrease
the risk of injury. Within the context of this definition, the workplace
includes not only the layout, but the design of everything the human uses to
accomplish a work related task. The human capacity includes aspects of the
"physical, physiological, biomechanical, and psychological/cognitive
capabilities". When there is a mismatch between the human's capabilities and
the task demands not only is there a loss of productivity, but the workers can
develop injuries related to cumulative trauma or instantaneous overloading of
the muscular system (e.g. strain/sprain). The incidence of these types of
injuries has a negative effect on industry as a result of documented injuries
and illnesses and costs of treating the injuries. These situations are
encountered typically when engineers fail to cater to the human aspects during
planning and execution of process flows or designing work places. The present
paper details efforts using ergonomics tools/methodologies which helped improve
the workplace and therefore improve the quality of life of the employees
performing groundskeeping tasks.
Title: Staffing Model Development
Speaker: Neal F. Schmeidler, OMNI
Engineering & Technology, Inc.
Human capital planning, based on sound
staffing models, provide information needed to formulate employment plans.
Staffing models help decision makers estimate the number of journey-level
personnel needed to perform one or more functions for a specific planning
period. Credible staffing models facilitate budget formulation, cost control,
alignment of resources to output expectations, workforce expansion/ contraction
planning, performance measurement, and more. This presentation will expand on
the CapSci 2010 discussion of steps to compute acceptable staffing models and
will include a new case study.
Title: A Critique of Contemporary Approaches to ATC Modernization: A
Personal Theory
Speaker: Donald Weitzman
Advances in computer hardware
and software technology now promise greater automation of the air traffic
control (ATC) process and a significantly different role for the controller.
Yet what passes for ATC modernization these days is often misdirected by the
accidents of what technological and computational tools are available. There is
still an enormous gap between the kind of automated processes that are
necessary to replace many of the activities of the controller and currently
available automated systems. Some automated tools have gained wide acceptance
as controller aids but quite incorrectly are being extended to replace rather
than to aid the controller. This paper will emphasize that ATC modernization
and the engineering models that drive it need to be better equipped with a dose
of common sense and humility. The ATC domain is not a theoretical world that
can be reduced to simple principles of engineering and physics. In the real
world of ATC, that world changes and is often driven by events that you cannot
foresee or predict. Put another way, in the real world of ATC, life is a lot
messier than engineering theory and computer science would have you
believe.

Meadowlark Botanical Gardens
Title: The Spiritual Magnitude of Nature: from Shandigar to the
Biodiversity Imperative.
Speaker: Keith P. Tomlinson, Manager and
Interpretive Naturalist, Meadowlark Botanical Gardens
The human-nature
relationship is truly ancient, preceding the rise of virtually all "organized"
religions by hundreds of thousands of years. Does this suppose a "predisposed
divinity" of the natural world in human consciousness'? Many of the most basic
traits and societal norms of interacting with nature suggest this. In the
United States more people visit zoos, aquaria and botanical gardens than all
professional sporting events combined. The pan-global use of plants and flowers
to celebrate religious and cultural events is one example of the aesthetic
pursuit of nature. Perhaps even more revealing is the use of funerary objects
from nature. This practice may date back well over fifty thousand years. Even
in the presence of various complex theological liturgies, human societies
remain deeply mystified over death and consistently reach out to nature to
process grief and bereavement. The first part of this presentation will review
concepts in the nature-faith continuum from a historical perspective. This will
focus on the global dispersion of liturgy based theologies during the Age of
Discover to parts of the world where nature based reverence was dominant. The
second part of the presentation will discuss the growing place of conservation
as a moral imperative within global faith communities and the evolving views
biodiversity conservation.
National Capital Area Skeptics
Title: CSI Skeptic
Speaker: Prof. Walter Rowe, Department of
Forensic Sciences, GWU
Network and cable television abound in shows with a
strong crime scene investigation/forensic science emphasis. But how much of the
forensic science shown on CSI (original, Miami and New York), Bones, NCIS,
Rizzoli and Isles or Body of Proof is accurate? This presentation will examine
some of the common errors made by the scriptwriters of these shows and by crime
novelists such as Patricia Cornwell and Jeffrey Deaver. It will also look at
scientific mistakes made by real crime scene investigators and forensic
scientists.
Title: Vaccines and Autism
Speaker: Prof. Marvin Zelkowitz,
Department of Computer Science, University of Maryland
Vaccines have been
shown to be among the most effective and inexpensive methods to prevent serious
diseases. Deadly diseases like polio, diphtheria, smallpox and measles have
largely disappeared in the United States. However, measles is making a comeback
in the United States and elsewhere, where it previously had all but
disappeared. And measles is not an innocent childhood sickness kids die
from it. A small but vocal group of parents are convinced that the measles
vaccine causes autism a lifelong affliction, even though there is no
evidence for that association. Where did that association come from, and what
is behind the vaccine scare is the topic of discussion.
Title: Top scams of 2012
Speaker: Prof. Marvin Zelkowitz, Department
of Computer Science, University of Maryland
Ever since there have been
people and money, there have been schemers intent on taking such money for
themselves. Outright theft was always an option, but carried the danger of
personal injury or death. A better way to obtain such funds was for the schemer
to convince the holder of the money that giving it up voluntarily was safest;
hence the scam. As we navigate in an increasingly electronic world, scams have
naturally moved to the Internet, where such schemers now have worldwide reach.
In this talk we will discuss the top scams currently in circulation and address
various ways to prevent yourself from being taken by one of these.
National Institute of Standards and Technology
Title: More than Just Standards: NIST Law Enforcement Standards Office
Forensic Science Program Update
Speaker: John Paul Jones II
A recent
survey revealed crime laboratory management is familiar with standard reference
materials produced by the National Institute of Standards and Technology
(NIST), such as the Human DNA Quantitation Standard. Yet there is so much more
activity taking place on the NIST campus than standards creation. The Forensic
Science Program (FSP) at the Law Enforcement Standards Office (OLES) within
NIST conducts and coordinates research and provides technical services to
address the needs of the forensic science community. The FSP focuses on
creating new material standards; initiating metrology research; evaluating
technologies; and establishing expert working groups to facilitate knowledge
exchange and identify best practices. These activities have been used to
support forensic science disciplines such as: arson; digital and multimedia
forensics; DNA; fingerprints; firearms and toolmarks; odontology; controlled
and dangerous substances; toxicology and trace analysis. Topics that will be
covered during this lecture include: " Expert Working Group on Human Factors in
Latent Print Analysis " Expert Working Group on the Preservation of Biological
Evidence " 3D Topography Correlations of Bullets and Casings " Photo scales and
Forensic Photogrammetry " Computer Forensics " NIST OLES's Research on the
Scientific Working Groups"
Title: Trace Explosive Detection Research Program at NIST
Speaker:
Greg Gillen, PhD Surface and Microanalysis Science Division Materials
Measurement Laboratory National Institute of Standards and Technology
The
NIST Surface and Microanalysis Science Division has been working to build a
chemical metrology program to help support the widespread operational
deployment and effective utilization of trace explosives detection devices
throughout the United States. A second objective is to develop at NIST the
specialized measurement expertise that will be needed to support the next
generation of explosive detection equipment. The low volatility of most high
explosives makes direct analysis of vapors impractical. Therefore, most
detection systems are based on either airborne or surface swipe collection of
micrometer-sized explosive particles with subsequent thermal vaporization of
the particles into an ion mobility spectrometer for identification. The
effective collection and thermal desorption of the explosive particles is the
critical front-end process for the successful and reproducible detection of
explosives. We are using existing expertise in particle analysis, analytical
chemistry and chemical microscopy to study the explosives collection and
detection process in detail. This information will be used to help facilitate
the continued development, characterization, calibration and standardization of
both tabletop and handheld explosive detection devices. This presentation will
include a discussion of our ongoing research in this area and a demonstration
of some of the advance metrology tools being used to characterize individual
explosive particles. Finally, some of our recent efforts in preparation of
standards for trace explosive detection will be discussed including the use of
drop-on-demand ink jet printing of explosives and the production of simulated
fingerprints containing explosive residues.
Title: NIST Fire Dynamics Analysis of the Station Night Club Fire
Speaker: Daniel Madrzykowski, PE, FSFPE Fire Research Division Engineering
Laboratory National Institute of Standards and Technology
A fire occurred
in The Station night club on the night of Feb. 20, 2003. The band performing
that night used pyrotechnics that ignited foam insulation lining the walls and
ceiling of the platform being used as a stage. The fire spread quickly along
the walls and ceiling area over the dance floor. Smoke was visible in the exit
doorways in a little more than one minute, and flames were observed breaking
through a portion of the roof in less than five minutes. Egress from the
nightclub was hampered by crowding at the main entrance to the building. One
hundred people lost their lives in the fire. The National Institute of
Standards and Technology (NIST), under the authority of the National
Construction Safety Team (NCST) Act, conducted an investigation to establish
the likely technical causes of the building failure that led to a high number
of casualties. This presentation focuses on the fire analysis portion of the
NIST technical investigation. Both physical and numerical simulations were
conducted and an overview of the results will be shown with videos and data.
The potential impact that an automatic sprinkler system would have had on the
fire is demonstrated. Throughout the presentation, the type of information or
materials that need to be collected when conducting a forensic fire
reconstruction will be discussed.
Title: Metrology Needs and NIST Resources for the Forensic DNA Community
Speaker: Michael D. Coble, PhD
Forensic DNA profiling was first used in
the mid-1980s and has been used to convict the guilty and exonerate the
innocent ever since. DNA typing has evolved from focusing on multi-locus
markers throughout the nuclear DNA genome to the use of autosomal Short Tandem
Repeat (STR) markers. Other marker systems such as mitochondrial DNA and
Y-chromosomal STR testing have also found an important niche in criminal cases,
the identification of missing persons, and historical investigations. Given the
importance of forensic DNA testing to the criminal justice system, it is
critical that all forensic DNA laboratories include proper controls and
validated procedures for making quality measurements. The National Institute of
Standards and Technology (NIST) Applied Genetics group has developed several
Standard Reference Materials (SRMs) to meet the needs of the forensic DNA
community. This presentation will discuss a brief history of forensic DNA
testing and the development of NIST SRMs, new assays/technologies, and
educational resources developed for the forensic DNA community over the last
twenty years.
Optical Society of America, National Capital Section
Title: Beryllium Receiver Telescopes for Space Lidar
Speaker: H.
John Wood, NASA Goddard Space Flight Center, Greenbelt, MD.
A brief history
of Beryllium receiver telescopes will be presented Voyager IRIS (1977)
through ICESat-2 ATLAS (2012). Opto-mechanical issues affecting the performance
of the telescope have become more important as the field of view is reduced to
improve signal to noise performance.
Title: A Partially Transparent Petaled Occulter for Exoplanet Detection
Speaker: Shahram (Ron) Shiri, NASA Goddard Space Flight Center, Greenbelt,
MD.
NASA's Exoplanet Exploration Program searches for habitable worlds and
life elsewhere in the Universe. One of the main focuses of this program is
direct imaging of exosolar planets and identification of Earth-like planets
orbiting bright stars. Since starlight is many orders of magnitude brighter
than light reflected by an orbiting planet, its detection presents a scientific
and technological challenge. Because of intensity enhancement by the Poisson
spot, a conventional circular disk cannot be used to reduce the starlight
brightness. Recent analysis of a partially apodized petaled occulter shows such
a structure could reduce the intensity along the optical axis behind the
occulter in excess of 10 orders of magnitude as required by NASA missions.
Title: Flexible displays for the Army
Speaker: Eric Forsythe, Army
Research Lab, 2800 Powder Mill Road, Adelphi, MD
The talk will present the
Army's advancements in flexible displays at the Flexible Display Center.
Reflective electrophoretic flexible displays have made significant advances
towards commercialization and system integration. The talk will present the
technology advances for organic light emitting diodes and the evolution to
flexible OLED displays. Finally, we will present future flexible electronics
concepts that leverage the display platform.
Title: Towards High-Efficiency Quantum-Dot Solar Cells
Speaker: K.
A. Sablon, Army Research Lab, 2800 Powder Mill Road, Adelphi, MD
According
to Shockley and Queisser, the maximum efficiency for the conversion of
unconcentrated solar radiation is 31%. A major factor limiting the conversion
efficiency in single junction cells is that sub-bandgap photons are not
absorbed. In response, low-dimensional quantum structures were proposed to be
used in solar cells, providing an approach complementary to the multi-junction
solar cells. Quantum dots (QDs) are very promising candidates with the
potential to create energy levels that can better match the solar spectrum.
They provide greater freedom in absorption band and strain engineering as
compared with bulk materials and QWs, with predicted efficiencies of ~64%.
However, experimental results have shown limited progress. In fact, introducing
dots into the solar cells give rise to additional channels of recombination,
which increase the recombination losses. To minimize the in turn decreases
recombination via QDs. These factors significantly improve the solar cell
conversion efficiency.
Title: "Painting With Light on a Canvas of Ice"
Speaker: Dr. Peter
Wasilewski, Emeritus Scientist, NASA Goddard Space Flight Center
This
session will feature a presentation of "Frizion" - the science of polarized
light transformed into art by NASA emeritus scientist Dr. Peter Wasilewski.
With a doctorate from the University of Tokyo and an abandoned football tryout
with the Baltimore Colts behind him, Pete explored and fell in love with the
ice of Antartica and stood where an ancient volcano now bears his name - Mount
Wasilewski. Through the medium of ice, a familiar and intriguing compound found
throughout the universe, and the principles of polarized light, Pete has
created a novel art form known as "Frizion". His presentation will contain
examples of his art and an explanation of the optical principles that are the
foundation of his creations.
Title: Lightweight and high angular resolution x-ray optics for
astronomical missions
Dr. Peter N. Blake, NASA Goddard Space Flight Center,
Greenbelt, MD.
Astronomical observation in the x-ray band (wavelength from
~100 - 0.1 Angstroms) must take place above the atmosphere on a space platform.
Imaging optics for the x-ray photons generally use the Wolter I design. Current
manifestations of that design include the Chandra X-Ray Observatory with
polished Zerodur shells offering high resolution, and Suzaku (formerly
ASTRO-EII) whose epoxy replicated aluminum foils trade off resolution
for high collection area. At the Goddard Space Flight Center, the Next
Generation X-Ray Optics program, headed by William W. Zhang, is developing a
new technology utilizing replicated thin glass mirrors that promises a new
high-resolution, high collection x-ray optical telescope.
Title: Photonics Experimentation for Military Applications
Speaker:
Richard L. Tober, Army Research Lab, 2800 Powder Mill Road, Adelphi, MD
Military applications are some of the most demanding in the world yet have
great potential for emerging technologies. Photonics, in particular, has an
ever increasing role on the battlefield. However, the path from concept to
transition can be difficult since access to relevant experimental environments
is outside the realm of most researchers. Fortunately though, OSD sponsors
Adaptive Red Team events that enable tactically significant experimentation. We
will describe how these venues provide an effective means to assess technology
alternatives, system limitations and vulnerabilities; and inspire collaborative
research. Specific examples of recent events and participating technologies
will be presented and discussed in terms of value added for improving the
photonic technologies.
Title: An Overview of Optical Biometrics for Military Applications
Speaker: Keith Aliberti, Army Research Lab, 2800 Powder Mill Road, Adelphi,
MD
Biometrics refers to the automatic identification of a person based on
his/her anatomical (e.g., fingerprint, iris) or behavioral (e.g., signature)
characteristics or traits. In the commercial world, this method of
identification has enabled some key advantages over traditional identification
methods (e.g. ID cards, PIN numbers, passwords, etc). As a result, biometric
systems are readily being deployed to enhance security and reduce financial
fraud. Over the last few years, optics- and photonics-based biometrics have
experienced an expanded role in military operations such as combat
identification (friend, foe, or neutral), offensive operations (intelligence
support to targeting), force protection (base access), detention operations,
civil-military operations (track target members of a population), and personnel
recovery and identification. To accomplish these tasks, various biometric
traits amenable to optical detection are being used for real-time recognition,
the most popular being face, iris and fingerprint. In addition, in some newer
applications, multi-modal biometrics are being employed to attain better
identification and verification. This talk will give an introduction to
Biometrics, discuss the current modalities, address future military
applications, and present some issues related to policy concerns over the
acquisition of biometric information.

Philosophical Society
Title: Wind and Solar -- the Past or the Future
Speaker: Kenneth
Haapala, former Executive Vice President of the Science and Environmental
Policy Project (SEPP) and current editor of The Week That Was (TWTW) - the
weekly bulletin of SEPP
The political leaders of many European nations,
such as Ireland, England, Germany, and Denmark, have committed their nations to
programs of closing traditional sources of electricity, such as coal
generation, and relying on alternative sources, such as wind and solar
generation. To varying degrees, twenty-nine states in the US have made similar
commitments. Generally, hard data is difficult to obtain, but that which is
available indicates that these programs will be costly and economically
destructive. The leaders committed to these sources before one-hundred-year old
technological problems have been solved. One problem is low-cost storage of
electricity on a commercial scale. A second problem, particularly in the US, is
transmission of electricity from possible producing areas in the West and
Midwest to the heavy consuming areas of the East. A brief overview of the
history of wind generated electricity in the US will be presented. The current
experiences of wind and solar projects in diverse locations will be discussed
to include critical assumptions that proved to be wrong. The selection of
projects will be based on the availability of data, not projections from future
endeavors. A robust, but proper, discussion will be encouraged.
Potomac Chapter of the Human Factors and Ergonomics Society
Title: Ensuring Exceptional Operator Performance: Psychological
Influences of Design through Human Systems Integration (HSI).
Speaker:
Gerald P. Krueger Krueger Ergonomics Consultants, Alexandria, VA
Since
World War II, engineering psychologists contributed immensely to making the
design of complex, sophisticated equipment user friendly. Initially,
efforts involved ensuring suitable operator usability in design of large
military systems. Subsequently, human factors specialists and industrial
engineers blended proven psychological and ergonomic principles to develop
user-centered designs of myriad configurations of human operated systems to
meet other government and commercial equipment procurement requirements (e.g.
in public transportation, medical, banking, communication systems, etc.) That
human-centered approach to design morphed into what is now called Human Systems
Integration (HSI) including early conceptual and developmental stage
considerations of seven human-oriented design domains: Manpower allocation (how
many people will be required to operate and maintain systems), Personnel
(identify the skills required), Training (new equipment training, school house
and sustainment training), Human Factors Engineering and Ergonomics, control of
Health Hazards associated with operating or maintaining equipment, System
Safety, Habitability and Personnel Vulnerability. The presentation provides a
short history of such developments, and highlights practical examples from
recent HSI activities in international border-crossing and airport security
screening measures, uniform protective clothing design, and more.
Title: Driver Opinions of Simulator-based Commercial Vehicle Training
Speakers: Justin Morgan, Myra Blanco, and Richard Hanowski Virginia Tech
Transportation Institute, Virginia Tech Blacksburg, VA
Simulator-based
training provides an opportunity to train drivers in a potentially lower cost
and safer environment than traditional, behind-the-wheel, methods of training.
As prices for commercial vehicle simulation equipment have fallen, some motor
carriers have adopted simulators for use during in-house driver training. The
result of focus groups with drivers who experienced truck simulator-based
training at two large motor carriers is presented. One carrier used the truck
simulator exclusively for regularly scheduled refresher training, while a
second used the simulator for both regular and novice (pre-commercial driver's
license) driver training. In general, drivers at both carriers had positive
opinions of simulator-based training. Most suggestions to improve the program
were directed towards modification of how the program was implemented and/or
creating a more realistic simulation of the driving environment.
Title: The Nature of Error: Implications for Health Care
Speaker:
Marilyn Sue Bogner Institute for the Study of Human Error Bethesda, Maryland
Despite over a decade of efforts directed to reducing health care error
including having care providers report their errors for accountability,
implementing financial disincentives for errors in health care facilities, and
instituting pay for performance all targeted to the health care provider, the
incidence of error has not decreased. Indeed, by some measures it has
increased. Nonetheless efforts to address error continue to focus on the health
care provider. One reason for this lies in the tenacious acceptance of
purported definitions of error which actually are descriptions of errors.
Although useful in determining trends those definitions do not address the
nature of error. The nature of error is the process by which an error occurs
the process involves action which is behavior. As attested in the
literature of all disciplines physical as well as social sciences
behavior of all entities of study is the function of the target entity
interacting with factors in the environment. Thus the approach that the health
care provider is the sole source of error is inaccurate and misleading. It is
little wonder that efforts based in that approach have not been fruitful in
reducing error. Considering the nature of error, that is, identifying and
addressing factors in the context of care that induce the care provider to act
in a manner that results in an error has profound implications for effectively
reducing health care error.
Salisbury University - Washington Academy of Sciences Student Chapter
Title: Temporal hierarchy of membrane restructuring during cold
acclimation in fish
Speaker: K. J. Ward and E. E. William, Department of
Biological Sciences, Salisbury University
Climate change may have dramatic
affects on the diversity and abundance of fish. It has been shown fish can
restructure membrane phospholipids to aid in their survival in response to a
change in water temperature. Biochemical evidence suggests these changes do not
occur at the same time or rate. Some reactions occur rapidly, whereas others
are delayed. We are currently trying to elucidate this hierarchy for mRNA
expression for reactions involved in membrane restructuring. We have developed
primers for many of the enzymes involved in these restructuring pathways
including de novo phospholipid synthesis, in situ phospholipid modifications
and phospholipid head group alterations. Our goal is to develop additional real
time probes based on PCR products obtained from primers designed for enzymes in
these restructuring pathways. To date, five such probes have been developed and
preliminary data show that changes in mRNA expression are occurring at
different rates. These data will help us further understand temperature
acclimation of fish at the molecular level. This work is supported by the
Department of Biological Sciences and the Henson School of Science and
Technology at Salisbury University.
Title: Temperature as a cellular stress
of Chinook salmon embryo cells
Speaker: A. Reese and E. E. Williams,
Department of Biological Sciences, Salisbury University
In this study, we
used Chinook salmon embryo cells (CHSE-214) to assess the relationship between
the timing of the expression of heat shock mRNAs and the timing of heat-induced
cell death. We first examined the timing of cell death [lactate dehydrogenase
(LDH) release] after a 24hr exposure to 22, 30, 37, 45, and 55oC. As expected,
cells did not release LDH after 24 hrs of exposure to their acclimation
temperature (22oC). At 30oC LDH release was detected beginning at 6, and all of
the cells were dead by 24hrs. Exposure to 37oC, LDH released at 3hrs; all cells
were dead by 6hrs. At 45oC the cells released LDH within the first hour, and
were all dead by 3hrs of exposure. At 55oC the cells began to release LDH
within the first 15mins, and were all dead within 1hr of exposure. mRNAs for
heat shock proteins were assessed at 37oC and it was found that the
constitutive heat shock protein (Hsc70) was present at all time points, and
there was no significant difference in the expression of the message for the
inducible form of the heat shock protein (Hsp70) over a 6 hour period. These
data will help us to further understand the molecular meaning of the critical
thermal max of fish. This project is supported by the Department of Biological
Sciences, and the Henson School of Science and Technology of Salisbury
University.
Title: Investigation of novel dipolar cycloaddtions of oxazolium
salts
Speaker: N. Elbers, L. Hill, and S. Habay, Department of Chemistry,
Salisbury University Our lab recently developed a new 1,3-dipolar cycloaddition
reaction of 2-acyl-5-amino oxazolium salts for the production of
cis-octahydroindole ring systems. These structural motifs are found in a
variety of medicinally relevant natural compounds, including the aeruginosin
and dysinosin families of natural products. Access to these compounds and other
analogs in larger quantities and through more efficient pathways would
facilitate medicinal research into new therapies. We present here our efforts
to widen the scope of our method by activation of the reaction substrates by
transition metals and advancements toward an asymmetric version of the
cycloaddition reaction.
Washington Academy of Sciences (Plenary)
Title: English as a Second Language: Analog Communication in a Digital
World
Panelists: Ted Cohen, University of Chicago, Paul Werbos, NSF, Richard
Hill, Washington Academy of Sciences
In a 1917 publication of a letter by a
British Admiral, the Oxford Dictionary discovered what may be the first use of
OMG ("Oh My God"). Almost a century later this term survives today with a
myriad of others, categorized in what we call Internet slang. This form of
slang has its roots in English, which is the most popular language spoken in
cyberspace, generating close to 80 percent of global electronic traffic.
Technical fluency is often judged on how well we communicate using both formal
and informal forms of English technical words, and more times than not brevity
is key when bandwidth restrictions or the haste of communicating an idea is
critical. Informal forms such as FFI (for further information) and PCM (please
call me) is not confined to technical communications, but can be found in
business and professional communication. Is the new language replacing the
traditional, expedited through the advancement of broadcasting and
computational technology? Who speaks this language; a new and tech-savvy global
class that can read and process modern hieroglyphs? And how on earth will they
talk with the rest of us? WDYT (What do you think?)
