Supporting Pre-Existing Teams in Crisis with IT: A Preliminary Organizational-Team Collaboration Framework

A number of pre-existing teams are trained to operate in crisis. These teams can be found in aviation, navy, nuclear power, offshore oil, air traffic control facilities, and trauma centers. Understanding how to support pre-existing teams like these, with IT is essential. To date, most support for these teams is automation support such as an electronic checklist for an airplane flight crew responding to an engine fire rather than collaboration support such as linking paramedics in the field to doctors in emergency rooms. While automated support is rapidly developing, very little consideration has been given to enhancing the collaboration support for teams that face crisis. With advances in network capacity and sensors, IT has enabled pre-existing teams that face crisis the opportunity to obtain collaboration support from others in the organization. Collaboration with other human experts is necessary to aid problem discovery and to consider ramifications of responses. Here we suggest a preliminary set of IT system guiding principles to support collaboration for a particular, but common type of pre-existing team that faces crisis. These principles are based on two frameworks that have been developed to mitigate the effects of crisis. One is an organizational approach called the High Reliability Organization (HRO); the other, a team approach, was developed in the aviation community known as Crew Resource Management (CRM). Here we briefly explain each approach, highlight their principles, and then suggest principles of a Collaboration Crisis IT (CCIT) system to support the collaboration needs of teams that face crisis

How Do Galaxies Form Their Stars Over Cosmic Time?

Galaxies in the past were forming more stars than those today, but the driving force behind this increase in activity remains uncertain. In this thesis I explore the origin of high star-formation rates today and in the past by studying the properties of gas and dust in the cold interstellar medium (ISM) of dusty galaxies over cosmic time. Critically, we do not yet understand how these galaxies could form so many stars. This work began with my discovery of unusual infrared (IR) emission line ratios in the class of dusty galaxies where most of the Universe’s stars were formed. To fully understand the source of these unusual emission line ratios, I turn to local analogs of the distant galaxies I study at high-redshift to investigate in detail the ratio of far-IR fine-structure line emission to mid-IR Polycylic Aromatic Hydrocarbons (PAHs). I find that gas within young star-forming regions heats and cools differently when it is compressed to high star-formation rate surface densities. I use radio spectroscopy of CO(1-0) and sub-millimeter dust continuum measurements to test how changes in heating and cooling impact the total gas reservoir, and find more efficient star- formation in compact galaxies at all redshifts. The high star-formation rates of distant galaxies may be sustained by this more efficient mode. With spatially resolved studies, I find the IR properties of star-forming, dusty galaxies to be comparable for fixed IR surface density at low- and high-redshift. Finally, to match the formation of stars with the synchronous growth of supermassive black holes I analyze numerical simulations of galaxy formation to study the radiative feedback of active galactic nuclei on dust. Rapidly accreting supermassive black holes can heat the dust in their host galaxies, powering a significant fraction of the cold dust luminosity and biasing IR-derived star-formation rates if left unaccounted for. With the recent launch of the James Webb Space Telescope, the future of extragalactic infrared observations is wide open and this research provides motivation for the continued study of the cold gas and dust conditions from which new stars form

MI Systems Taxonomy

Systems theory is often used in MIS research and applications. It is frequently assumed that the underlying principles of system theory are shared by both the author and audience. However, as will be presented here, multiple variants of systems theory exist, with often conflicting basic tenets which can lead authors and audiences to misunderstanding. This paper offers a taxonomy of four systems theories. Brief suggestions for applications of each are made. The limitations of systems theories are presented

Stem cells and fluid flow drive cyst formation in an invertebrate excretory organ.

Cystic kidney diseases (CKDs) affect millions of people worldwide. The defining pathological features are fluid-filled cysts developing from nephric tubules due to defective flow sensing, cell proliferation and differentiation. The underlying molecular mechanisms, however, remain poorly understood, and the derived excretory systems of established invertebrate models (Caenorhabditis elegans and Drosophila melanogaster) are unsuitable to model CKDs. Systematic structure/function comparisons revealed that the combination of ultrafiltration and flow-associated filtrate modification that is central to CKD etiology is remarkably conserved between the planarian excretory system and the vertebrate nephron. Consistently, both RNA-mediated genetic interference (RNAi) of planarian orthologues of human CKD genes and inhibition of tubule flow led to tubular cystogenesis that share many features with vertebrate CKDs, suggesting deep mechanistic conservation. Our results demonstrate a common evolutionary origin of animal excretory systems and establish planarians as a novel and experimentally accessible invertebrate model for the study of human kidney pathologies

Hot Accretion With Conduction: Spontaneous Thermal Outflows

Motivated by the low-collisionality of gas accreted onto black holes in Sgr A* and other nearby galactic nuclei, we study a family of 2D advective accretion solutions with thermal conduction. While we only impose global inflow, the accretion flow spontaneously develops bipolar outflows. The role of conduction is key in providing the extra degree of freedom (latitudinal energy transport) necessary to launch these rotating thermal outflows. The sign of the Bernoulli constant does not discriminate between inflowing and outflowing regions. Our parameter survey covers mass outflow rates from ~ 0 to 13% of the net inflow rate, outflow velocities from ~0 to 11% of the local Keplerian velocity and outflow opening angles from ~ 0 to 60 degs. As the magnitude of conduction is increased, outflows can adopt a conical geometry, pure inflow solutions emerge, and the limit of 2D non-rotating Bondi-like solutions is eventually reached. These results confirm that radiatively-inefficient, hot accretion flows have a hydrodynamical propensity to generate bipolar thermal outflows.Comment: 38 pages, 10 figures, accepted for publication in Ap
