Digital Natives or Digital Morons? An “Internal” Debate on Technology and Critical Thinking Skills
Creators: name: Muir, Star
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2010
Subjects: pedagogy; critical thinking

description: Are video games, media rich environments, and social networking technologies producing collaborative and experienced problem-solvers and decision-makers, or are we creating (as one author titles it) the “Dumbest Generation”? Is our educational system focusing on old skills for an industrial society, or preparing nimble and flexible students for jobs that don’t even exist yet? Prensky, Jukes, Rosen, McCain and others have lionized the impact of new digital technologies and the need for digital “immigrants” to refashion their teaching and step out of the “test and tell” model of talking heads. Bauerlein, Jackson, Zittrain, Oppenheimer and others foresee the rise of a new dark age, and decry the insidious influence of the internet and new communication technologies on attention spans, research habits, and test scores. This presentation features a solitary debater torn between two worldviews, presenting arguments and gibes from both sides, with a distributed annotated bibliography and Q&A periods for audience interaction. Constructive speeches will be followed by extended cross-examination time, concluding with summary rebuttals and general discussion.

description: Tuberculous meningitis (TBM) is the most devastating form of tuberculosis (TB) but diagnosis is difficult and delays in initiating therapy increase mortality. All currently available tests are imperfect; culture of Mycobacterium tuberculosis from the cerebrospinal fluid (CSF) is considered the most accurate test but is often negative, even when disease is present, and takes too long to be useful for immediate decision making. Rapid tests that are frequently used are conventional Ziehl-Neelsen staining and nucleic acid amplification tests such as Xpert MTB/RIF and Xpert MTB/RIF Ultra. While positive results will often confirm the diagnosis, negative tests frequently provide insufficient evidence to withhold therapy. The conventional diagnostic approach is to determine the probability of TBM using experience and intuition, based on prevalence of TB, history, examination, analysis of basic blood and CSF parameters, imaging, and rapid test results. Treatment decisions may therefore be both variable and inaccurate, depend on the experience of the clinician, and requests for tests may be inappropriate. In this article we discuss the use of Bayes' theorem and the threshold model of decision making as ways to improve testing and treatment decisions in TBM. Bayes' theorem describes the process of converting the pre-test probability of disease to the post-test probability based on test results and the threshold model guides clinicians to make rational test and treatment decisions. We discuss the advantages and limitations of using these methods and suggest that new diagnostic strategies should ultimately be tested in randomised trials.
LATIST: A Performance Support Tool for Integrating Advanced Learning Technologies into Course Design

Subjects: digital tools; pedagogy; digital pedagogy;

description: This session will present a patent pending tool called LATIST which stands for Learning Asset Technology Integration Support Tool. This performance support tool enables faculty to integrate Advanced Learning Technologies (ALT) such as social media, mobile technologies, games, simulations, and virtual worlds into their course designs. Specifically LATIST has three
components: (a) Explore Research which allows users to explore what the research says about a specific ALT and examine its advantages, disadvantages, and best practices in teaching and learning contexts; (b) Select Best Technology which allows users to select instructional strategies and technologies based on course objectives and factors such as bandwidth and budget; and (c) Apply Technology which allows users to view real world examples of ALT use in educational and training settings as well as practice using a selected technology.
LATIST was developed as a result of funding provided by the US Army Research Development & Engineering Command (RDECOM) to support research on ALT for the Defense Acquisition
University (DAU). The goals of LATIST are to facilitate decision making among DAU faculty and staff by providing (a) a pedagogically driven decision support tool; (b) a repository of research on technology use in government, business, and education; and (c) access to information on how to integrate technology within learning assets. LATIST is also designed as a method to raise awareness of technology options and provide a tool for faculty and staff to refer to when making learning technology decisions. As research and resources on ALT are constantly growing and evolving, LATIST is designed to be scalable and encourages user interaction by embedding capabilities such as tagging, saving, sharing, and uploading within the tool. This session will describe the usage centered design process that was used by GMU faculty and students to develop LATIST and will demonstrate the tool and its components.

description: In the protogalactic density field, diffuse gas and collision-less cold dark matter (DM) are often assumed sufficiently mixed that both components experience identical tidal torques. However, haloes in cosmological simulations consistently end up with a higher specific angular momentum (sAM) in gas, even in simulations without radiative cooling and galaxy formation physics. We refine this result by analysing the spin distributions of gas and DM in $\sim$50,000 well-resolved haloes in a non-radiative cosmological simulation from the SURFS suite. The sAM of the halo gas on average ends up $\sim$40\% above that of the DM. This can be pinned down to an excess AM in the inner halo ($<$50\% virial radius), paralleled by a more coherent rotation pattern in the gas. We uncover the leading driver for this AM difference through a series of control simulations of a collapsing ellipsoidal top-hat, where gas and DM are initially well mixed. These runs reveal that the pressurised inner gas shells collapse more slowly, causing the DM ellipsoid to spin ahead of the gas ellipsoid. The arising torque generally transfers AM from the DM to the gas. The amount of AM transferred via this mode depends on the initial spin, the initial axes ratios and the collapse factor. These quantities can be combined in a single dimensionless parameter, which robustly predicts the AM transfer of the ellipsoidal collapse. This simplistic model can quantitatively explain the average AM excess of the gas found in the more complex non-radiative cosmological simulation.

description: A wide-frequency radio study of Active Galactic Nuclei (AGN) is crucial to evaluate the intervening radiative mechanisms responsible for the observed emission and relate them with the underlying accretion physics. We present wide frequency (5-45 GHz), high-sensitivity (few microJy/beam), (sub)-kpc JVLA observations of a sample of 30 nearby (0.003 < z < 0.3) AGN detected by INTEGRAL/IBIS at hard-X-ray. We find a high detection fraction of radio emission at all frequencies, i.e. > 95 per cent at 5, 10 and 15 GHz and > 80 per cent at 22 and 45 GHz. Two sources out of 30 remain undetected at our high sensitivities. The nuclear radio morphology is predominantly compact, sometimes accompanied by extended jet-like structures, or more complex features. The radio Spectral Energy Distributions (SEDs) of the radio cores appear either as a single or as a broken power-law, a minority of them exhibits a peaked component. The spectral slopes are either flat/inverted or steep, up to a break/peak or over the whole range. The sample mean SED shows a flat slope up to 15 GHz which steepens between 15 and 22 GHz and becomes again flat above 22 GHz. Significant radio-X-ray correlations are observed at all frequencies. About half of the sample features extended emission, clearly resolved by the JVLA, indicating low-power jets or large scale outflows. The unresolved cores, which often dominate the radio power, may be of jet, outflow, and/or coronal origin, depending on the observed frequency.

PULSED LASER AS NEW TOOLS FOR CONTROLLED NANOMANUFACTURING AND SCIENTIFIC RESEARCH IN SOLUTION-BASED CHEMICAL SYNTHESIS
Creators: name: Liu, Siyu
Publisher: name: Purdue University Graduate School
Year: 2022
Subjects: Nanomanufacturing

description: Pulsed lasers are studied as new tools to realize competitive nanomanufacturing. The capabilities of pulsed lasers as promising tools for research, design, manufacturing, and control rely on the flexibility due to the great variety of operation parameters, and the inherent precision in aspects of time, spatial resolution, and energy input. As new tools, the fundamental understanding and technological capabilities of pulsed laser-induced chemical synthesis were explored in this dissertation research. In order to study the capabilities of pulsed laser in controlled synthesis, a thermal model was developed to predict the local temperature change due to the very short period of irradiation by a pulsed laser. And combining with the classical Gibbs free energy theories, a set of guidelines were developed for precision control for pulsed laser-induced chemical synthesis. Zinc oxide crystals were studied as an example case, showing the relationship between the wide range variables of pulsed laser including repetition rate, energy area density, power density, irradiation duration, etc. and the material structures of deposited crystals in aspects of crystal density, size, shape, crystalline properties, surface morphologies, growth rate, etc. Mechanisms from thermodynamic and kinetic aspects were explored. Pulsed laser-induced different heating conditions were found to separate two crystallization processes with different energy barriers, one dominated by a burst of nucleation and the other dominated by crystal growth through particle aggregation. For the study of the fundamental mechanisms in crystallization, pulsed laser initiated and controlled the crystallization in its early stage, and the crystal evolution were observed and analyzed by transmission electron microscopy (TEM). Crystal growth from intermediate monomers was first studied by an electron beam under the condition without precursor solution environment, providing crucial process information of crystal evolution, indicating multistage processes by continuous mass and phase transfer among intermediate monomers. This dissertation shows the capabilities of pulsed laser in realizing precision control for the targeted synthesis in nanomanufacturing, providing unique insight to crystallization mechanisms, and extending prospects to scientific research of other energy beam induced processes.

title: Investigating the role of mitochondria in regulating cell health and ageing
Creators: name: Dennis, Nathan
Publisher: name: University of Kent
Year: 2022

description: Reactive oxygen species (ROS) are highly reactive oxygen-containing compounds which are thought to have detrimental effects on cell health and ageing. Mitochondrial dysfunction is generally considered to elevate ROS production due to respiratory enzymes in the electron transport chain (ETC) engaging in side reactions with oxygen. However, countless attempts to alleviate mitochondrial ROS accumulation in model organisms have failed to yield improvements in cellular health or ageing. In addition, respiratory-incompetent Saccharomyces cerevisiae cells lacking the ETC CIV subunit Cox4p accumulate high levels of ROS not via the ETC, but via an ER-bound NADPH oxidase named Yno1p. The loss of Cox4p causes Ras2p to associate with the mitochondrial outer membrane, repressing the degradation of Yno1p by the endoplasmic reticulum-associated degradation pathway (ERAD). This process is in turn dependent on the bromodomain-containing transcription factor, Bdf1p, which, in Δcox4 cells, appears to dissociate from acetyl-lysine residues in histone tails and localise to the mitochondria alongside Ras2p. Here I propose that by impairing mitochondrial function, the loss of Cox4p downregulates cytosolic acetyl-CoA biosynthesis, resulting in histone hypoacetylation, and that by dissociating from hypoacetylated histones, Bdf1p serves to tether the histone acetylation state to ROS accumulation in Δcox4 cells. I demonstrate that the loss of Cox4p elevates ROS levels approximately 37-fold relative to WT cells and is associated with the downregulation of many genes involved in acetyl-CoA biosynthesis. Further, I show that the loss of Cox4p is associated with the downregulation of genes enriched for acetylated histone lysine residues. Lastly, I demonstrate that increasing the levels of acetyl-CoA, either by overexpressing the cytosolic acetyl-CoA synthetase ACS2 or by supplementing cultures with potassium acetate, is sufficient to decrease ROS accumulation in Δcox4 cells and, in the case of the latter intervention, virtually eliminate it. These results indicate that defective acetyl-CoA metabolism is crucial for the accumulation of ROS in Δcox4 cells, and ought to spur further research into the links between metabolism and ROS accumulation in other organisms and under different conditions of respiratory deficiency.

description: Adult mammalian cardiomyocytes (CMs, or heart muscle cells) have little, if any, ability to proliferate in response to injury, and after myocardial infarction this defect underlies the poor regenerative ability of human hearts. In contrast, early stage of CMs (such as fetal CMs) still have some ability to proliferate, and we seek to identify novel gene regulators as potential therapeutic targets for heart regeneration. Here we use human pluripotent stem cells (hPSCs) as an in vitro human model to investigate the roles of emerging long non-coding RNAs (lncRNAs), with the lengths of over 200 nucleotides are able to be transcribed but not translated into protein, for heart regeneration. With public available RNA-sequencing data, we identified several human genes, including lncRNAs, that are highly enriched in fetal CMs. We generated targeted gene knockout hPSC lines using CRISPR/Cas9-mediated genome editing and will use them to study the roles of selected genes in regulating CM proliferation. To identify more therapeutic targets, we also generated a fluorescence ubiquitination cell cycle indicator (FUCCI) reporter cell line that express either green (indicating dividing cells) or red fluorescence (indicating non-dividing cells), on which we’ll perform unbiased genome-wide screening to identity genes that regulate CM proliferation. High-throughput chemical screening will also be performed on FUCCI reporter lines to identify potential therapeutic drugs for heart regeneration.

Processes level laboratory experiments, field experiments, modeling, economic data,
and risk theory are used to support the

description: The spectroscopic evolution of Hen\,3-1357, the Stingray Nebula, is presented by analysing data from 1990 to 2021. High resolution data obtained in 2021 with South African Large Telescope High Resolution Spectrograph and in 2009 with European Southern Observatory-Very Large Telescope UVES spectrograph are used to determine physical conditions and chemical abundances in the nebula. From comparison of these data with data from different epochs it is found that the intensity of highly-ionized emission lines has been decreasing with time, while the emission of low-ionization lines has been increasing, confirming that the nebula is recombining, lowering its excitation class, as a consequence of the changes in the central star which in 2002 had an effective temperature of 60,000 K and from then it has been getting colder. The present effective temperature of the central star is about 40,000 K. It has been suggested that the central star has suffered a late thermal pulse and it is returning to the AGB phase. The nebular chemistry of Hen\,3-1357 indicates that all the elements, except He and Ne, present sub solar abundances. The comparison of the nebular abundances with the values predicted by stellar nucleosynthesis models at the end of the AGB phase, shows that the central star had an initial mass lower than 1.5 M$_{\odot}$. We estimated the ADF(O$^{+2}$) to be between 2.6 and 3.5.

Modeling Forchheimer fractures as interfaces

Publisher: name: XVI International Conference on Computational Methods in Water Resources
Year: 2006

description: Modeling flow and transport of contaminants in porous media is made difficult by the
presence of heterogenieties in the characteristics of the medium occurring at scales
quite different from those describing the average characteristics of the medium.  One
particular instance of this phenomena is the occurrence of fractures in the medium,
regions very small in width but very important for modeling flow because of their
much higher (or possibly much lower ) permeability.  Fine networks of interconnected
fractures occurring with some degree of regularity are often taken into account by
double porosity models.  Here however we are concerned with larger fractures or
faults of known location that need to be included specifically in the model. In
earlier works, a model was introduced in which the fracture was treated as a lower
dimensional domain, as an interface between two subdomains, and domain decomposition
techniques with nonlocal interface conditions were used to solve the equations. The
porous medium was divided into subdomains with some of the interfaces representing
fractures.  At these fracture interfaces, the flux continuity condition was replaced
by an equation representing Darcy flow along the interface.
When the flow in the fracture is sufficiently rapid however, inertial effects need
to be taken into account, and Forchheimer's law describes the flow in the fracture
more accurately than does Darcy's law.  The object of this presentation is to extend
the above model to the case in which the flow along the fracture is governed by
Forchheimer's law.  As Forchheimer's law is given by a nonlinear equation, this model
is more complex.  It is derived by averaging across the fracture under the assumption
that the flow in the direction normal to the fracture is less important than in
directions tangential to the fracture.  Domain decomposition type techniques can
still be used as the nonlinearities involve only the interface unknowns.  A
quasi-Newton method can then be used to solve the resulting nonlinear problem on the
interfaces.  In this presentation the numerical model will be derived and numerical
results will be presented.

description: NGC 4395 is a dwarf galaxy at a distance of about 4.3 Mpc (scale: ~0.021 pc mas$^{-1}$). It hosts an intermediate-mass black hole (IMBH) with a mass between ~10$^4$ and ~10$^5$ solar masses. The early radio observations of NGC 4395 with the very long baseline interferometry (VLBI) network, High Sensitivity Array (HSA), at 1.4 GHz in 2005 showed that its nucleus has a sub-mJy outflow-like feature (E) extending over 15 mas. To probe the possibility of the feature E as a continuous jet with a base physically coupled with the accretion disc, we performed deep VLBI observations with the European VLBI Network (EVN) at 5 GHz, and analysed the archival data obtained with the HSA at 1.4 GHz in 2008, NSF's Karl G. Jansky Very Large Array (VLA) at 12-18 GHz and the Atacama Large Millimetre/submillimetre Array (ALMA) at 237 GHz. The feature E displays more diffuse structure in the HSA image of 2008 and has no compact substructure detected in the EVN image. Together with the optically thin steep spectrum and the extremely large angular offset (about 220 mas) from the accurate optical Gaia position, we explain the feature E as nuclear shocks likely formed by the IMBH's episodic ejection or wide-angle outflow. The VLA and ALMA observations find a sub-mJy pc-scale diffuse feature, possibly tracing a thermal free-free emission region near the IMBH. There is no detection of a jet base at the IMBH position in the VLBI maps. The non-detections give an extremely low luminosity of <=4.7 x 10$^{33}$ erg s$^{-1}$ at 5 GHz and indicate no evidence of a disc-jet coupling on sub-pc scales.

description: Bright debris discs can contain large amounts of CO gas. This gas was thought to be a protoplanetary remnant until it was recently shown that it could be released in collisions of volatile-rich solids. As CO is released, interstellar UV radiation photodissociates CO producing CI, which can shield CO allowing a large CO mass to accumulate. However, this picture was challenged because CI is inefficient at shielding if CO and CI are vertically mixed. Here, we study for the first time the vertical evolution of gas to determine how vertical mixing affects the efficiency of shielding by CI. We present a 1D model that accounts for gas release, photodissociation, ionisation, viscous evolution, and vertical mixing due to turbulent diffusion. We find that if the gas surface density is high and the vertical diffusion weak ($α_{\rm v}/α<[H/r]^2$) CO photodissociates high above the midplane, forming an optically thick CI layer that shields the CO underneath. Conversely, if diffusion is strong ($α_{\rm v}/α>[H/r]^2$) CI and CO become well mixed, shortening the CO lifetime. Moreover, diffusion could also limit the amount of dust settling. High-resolution ALMA observations could resolve the vertical distribution of CO and CI, and thus constrain vertical mixing and the efficiency of CI shielding. We also find that the CO and CI scale heights may not be good probes of the mean molecular weight, and thus composition, of the gas. Finally, we show that if mixing is strong the CO lifetime might not be long enough for CO to spread interior to the planetesimal belt where gas is produced.

description: This presentation concerns flow in a porous medium with one or more faults or
fractures.  In the model to be presented the fractures are treated as interfaces
between neighboring subdomains.  Then a domain decomposition method, in which the
transmission conditions are continuity of the pressure and Darcy flow along the n-1
dimensional fracture interface, is formulated.  In an earlier article the model
for a domain with a single fracture was defined, existence and uniqueness of the
solution were shown, error estimates were obtained and numerical results were shown
for a simple two dimensional problem.  Here the case of intersecting fractures is
treated by imposing continuity of the pressure and continuity of the flux at the
intersection of the fractures. This is a more complicated problem both theoretically
and from the point of view of implementation. To accelerate the rate of convergence
of the iterative procedure  a preconditioner is proposed. This preconditioner is
based on the observation that in the equation to be solved on the interfaces, the
operator corresponding to the Darcy flow along the fracture is of higher order than
those corresponding to the Steklov-Poincare operators associated with the neighboring
subdomains.  Examples and tests evaluating the performance of this preconditioner for
a three dimensional model with intersecting fractures are presented. The behavior of
the preconditioner with respect to mesh refinement is illustrated. The preconditioner
is also compared with a more standard preconditioner.

description: The aim of this talk is to present a new framework for characterisation of porous
materials and for obtaining first-principles structure-property relations. The method
is constructed in several steps. First, the skeleton of the porous medium is
characterised using a new fabric tensor that describes the local pore structure. For
materials made of relatively rigid particles the skeleton consists of the network of
inter-particle contacts. Second, the fabric tensor is used to construct a
configurational entropy of the porous medium, based on Edwards’ compactivity concept
from statistical physics. Both the fabric tensor and the entropic analysis are
initially illustrated in two-dimensions and are then extended to three-dimensional
systems. This formulation has proved useful in investigating the elastic properties
fo granular and foamy materials. Using the entropic approach, we will be able, in the
future,  to calculate the permeability, electrical conductivity and other macroscopic
properties, in terms of the statistics of the skeleton. Since these macroscopic
properties are all linked to the same microscopic structural characterisation we
expect to be able to derive theoretical relations between them.

description: Urbanizing watersheds are facing many challenges and significant efforts are being made to protect receiving water quality and the natural habitats in the watersheds. In the Sweetwater River watershed, current efforts focus primarily on urban runoff since stormwater from urban land uses has been identified as a major source of contamination to the Sweetwater reservoir. Urban land use information is being used to estimate and manage stormwater runoff pollution. Although there have been several monitoring and modeling efforts to predict stormwater quality, few attempts have been made to spatially estimate pollutant loadings. In this research, we estimated stormwater pollutant loadings from land use data and generated spatial estimates of pollutant loading in the watershed. Our goal was to identify the areas that discharge high pollutant loading and to visualize this information by generating pollutant loading maps. The result shows that commercial, public, industrial, and transportation land uses are important to manage stormwater pollution despite their small area and are early targets for best management practices (BMPs). The results can be used to develop BMPs and to assist in developing urban runoff diversion systems to protect the Sweetwater reservoir.

description: Cities across the United States are reversing the historical trend toward urban sprawl by encouraging more densely developed, mixed-use communities. These efforts provide protection for rural and natural areas, but strain existing urban infrastructure. As a result of denser developments and the resulting increase of impervious roofs and pavements under traditional construction practices, jurisdictions must increase their storm drainage capacities, which is a costly solution. Many are looking to sustainable approaches using natural systems to help slow the stormwater flows while providing a means of cleaning the water. These natural systems can provide a more flexible infrastructure of conveyance and treatment while adding an aesthetic to the community. Sustainable approaches however, often involve unconventional designs requiring variances to current standards. As a result, project proponents have the added responsibility of convincing the permitting agency that the design will meet the intent of Code requirements. It has taken dedication from sustainable design pioneers at the local level to push through the first projects. As more projects incorporate sustainable technologies, there will be more opportunities to educate the public and monitor their long-term performance and benefits. In time there will be a familiarity with these innovative sustainable design components of today to become our codes and standards of tomorrow.

description: The study deals with one of the critical aspects of the Road Departure Mitigation System. The first part of the study finds out what all color combinations and patterns represent the US roadside curbs, what should be the range of Radar Reflectivity values, and LiDAR Reflectance bounds that a surrogate curb should satisfy. The later part of the thesis illustrates methods and steps on how to mimic the extracted properties, design a surrogate curb as per federal standards, and then develop a surrogate curb.

description: The 1.33 mm survey of protoplanetary discs in the Taurus molecular cloud found annular gaps and rings to be common in extended sources (>~55 au), when their 1D visibility distributions were fit parametrically. We first demonstrate the advantages and limitations of nonparametric visibility fits for data at the survey's 0.12" resolution. Then we use the nonparametric model in Frankenstein ('frank') to identify new substructure in three compact and seven extended sources. Among the new features we identify three trends: a higher occurrence rate of substructure in the survey's compact discs than previously seen, underresolved (potentially azimuthally asymmetric) substructure in the innermost disc of extended sources, and a 'shoulder' on the trailing edge of a ring in discs with strong depletion at small radii. Noting the shoulder morphology is present in multiple discs observed at higher resolution, we postulate it is tracing a common physical mechanism. We further demonstrate how a super-resolution frank brightness profile is useful in motivating an accurate parametric model, using the highly structured source DL Tau in which frank finds two new rings. Finally we show that sparse (u, v) plane sampling may be masking the presence of substructure in several additional compact survey sources.

description: The primary objective of the paper is to draw upon the experiences acquired in many parts of the world to provide an up-to-date summary of the state of the practice for source control techniques and approaches, in a sustainable development context. After a discussion of the prevailing context for urban drainage approaches, three main themes covering techniques and design criteria, institutional aspects and performance issues are discussed relative to source control implementation. The discussion is based on findings from the compilation and analysis of available literature, recently developed databases, the experience of the different members of the SOCOMA group and recent research on design methodologies that explicitly seek to better couple effective design and achievement of performance goals. The paper also discusses perceived trends in the selection, analysis, and implementation of source controls, highlighting the areas where knowledge is lacking and providing recommendations on needs for future research.
