    The DOE Weatherization Training Grant assisted Native American trainees in developing weatherization competencies, creating employment opportunities for Bishop Paiute tribal members in a growing field. The trainees completed all the necessary training and certification requirements and delivered high-quality weatherization services on the Bishop Paiute Reservation. Six tribal members received all three certifications for weatherization; four of the trainees are currently employed. The public benefit includes (1) development of marketable skills by low-income Native individuals, (2) employment for low-income Native individuals in a growing industry, and (3) economic development opportunities that were previously not available to these individuals or the Tribe.

  4. The "Splendid Isolation" of Aaron T. Beck.

    Rosner, Rachael I

    2014-12-01

    Aaron T. Beck's Cognitive Therapy (CT) is a school of psychotherapy, conceived in the 1960s, that is celebrated by many clinicians for having provided the scientific antidote to all that was wrong with psychoanalysis. This essay situates the origins of CT in the crisis of legitimacy in psychiatry in the 1960s and 1970s, when, among many charges, psycho- analysts had to face the accusation that analysis was not adequately scientific. Beck actually began his career as both a psychoanalyst and an experimentalist. Contrary to common triumphalist accounts, Beck created CT to be a neutral space, not a partisan one, in turbulent times. Other notable psychoanalysts also sought compromise, rather than partisanship, to bridge the transition to biomedical science. The biographical approach of this essay to the origins of Beck's CT both situates him historiographically and articulates the complex experiences of a generation of psychoanalysts otherwise opaque to standard narratives.

  8. Geophysicists: Jules Aarons (1921-2008)

    NASA Astrophysics Data System (ADS)

    Mendillo, Michael

    2009-03-01

    Jules Aarons, a pioneer in satellite radio beacon studies of the ionosphere, died peacefully at his home in Newton, Mass., on 21 November 2008 at age 87. When considering his college career, Jules was drawn toward the humanities, an interest subsequently redirected by his parents toward science as a more suitable way to earn a living, and then by the U.S. Army Air Corps toward radio technology as a more suitable way to win World War II. Both goals were readily accomplished, perhaps instilling in Jules the value of proper mentorship, that central aspect of his life that so dominates our recollections of him. After the war, and with a variety of options before him, Jules decided upon civilian government service at the U.S. Air Force's then new field station in Cambridge, Mass. This was the founding entity of the Air Force Cambridge Research Laboratory (AFCRL), and those five famous letters became identified with his professional career (1946-1981). With Russia's launch of Sputnik in 1957, the era of space-based radio communications began, and with it the need to understand the sporadic crackling and fading (``scintillations'') of radio transmissions from satellites to ground receiving stations. Wartime efforts also gave birth to radio astronomy. Jules fostered ways to fund the synergies he saw between the radio technologies of space science and those of ground-based radio astronomy in ways almost unimaginable today (and certainly not by former U.S. senator Mike Mansfield, whose 1973 amendment to the U.S. Congress's defense appropriations bill limited the financing of basic research by military agencies only to projects that have direct military consequences; the amendment resulted in a permanent restructuring of how U.S. Department of Defense (DOD) agencies fund university-based research).

  17. The 2009 Lindau Nobel Laureate Meeting: Aaron Ciechanover, Chemistry 2004

    PubMed Central

    Ciechanover, Aaron

    2009-01-01

    Aaron Ciechanover was born in Haifa, Israel in October 1947. He shared the Nobel Prize in Chemistry in 2004 with Avram Hershko and Irwin Rose for their discovery of ubiquitin-mediated protein degradation. When Ciechanover began his work on proteolysis, the field was outside the realm of scientific mainstream as many thought that the fundamental secrets relating to sequence specificity were relevant to the synthetic side, or code side. The notion that specific sequences could selectively guide a destructive process did not naturally occur to scientists including Ciechanover himself. The emergence of controversial evidence demonstrating a requirement for metabolic energy in intracellular protein degradation, refuted the idea that cellular proteolysis was an entirely exergonic process occurring in the lysosome and prompted Ciechanover, Hershko, and Rose to "launch an attack" on the system, in order to uncover true pathway. Later findings of Ciechanover and subsequent groups showed that not only was the process energy-dependent, but that 8% of the human genome is remarkably one large ubiquitin system. Following the recapitulation and reflection of his work, Ciechanover shares insights into his principal and philosophical approach to science and life altogether. The life and work of Aaron Ciechanover are deeply rooted and influenced by Judaism and Israel and it is therefore that with only brief intermission, Ciechanover spent his scientific career in Israel as he is - through his presence and work - able to contribute and shape presence and future of the State of Israel.

  18. Rapid Crystallization of the Bishop Magma

    NASA Astrophysics Data System (ADS)

    Gualda, G. A.; Anderson, A. T.; Sutton, S. R.

    2007-12-01

    Substantial effort has been made to understand the longevity of rhyolitic magmas, and particular attention has been paid to the systems in the Long Valley area (California). Recent geochronological data suggest discrete magma bodies that existed for hundreds of thousands of years. Zircon crystallization ages for the Bishop Tuff span 100-200 ka, and were interpreted to reflect slow crystallization of a liquid-rich magma. Here we use the diffusional relaxation of Ti zoning in quartz to investigate the longevity of the Bishop magma. We have used such an approach to show the short timescales of crystallization of Ti-rich rims on quartz from early- erupted Bishop Tuff. We have now recognized Ti-rich cores in quartz that can be used to derive the timescales of their crystallization. We studied four samples of the early-erupted Bishop. Hand-picked crystals were mounted on glass slides and polished. Cathodoluminescence (CL) images were obtained using the electron microprobe at the University of Chicago. Ti zoning was documented using the GeoSoilEnviroCARS x-ray microprobe at the Advanced Photon Source (Argonne National Lab). Quartz crystals in all 4 samples include up to 3 Ti-bearing zones: a central core (50-100 μm in diameter, ca. 50 ppm Ti), a volumetrically predominant interior (~40 ppm Ti), and in some crystals a 50-100 μm thick rim (50 ppm Ti). Maximum estimates of core residence times were calculated using a 1D diffusion model, as the time needed to smooth an infinitely steep profile to fit the observed profile. Surprisingly, even for the largest crystals studied - ca. 2 mm in diameter - core residence times are less than 1 ka. Calculated growth rates imply that even cm-sized crystals crystallized in less than 10 ka. Crystal size distribution data show that crystals larger than 3 mm are exceedingly rare, such that the important inference is that the bulk of the crystallization of the early-erupted Bishop magma occurred in only a few thousand years. This timescale

  20. Culture in salutogenesis: the scholarship of Aaron Antonovsky

    PubMed Central

    Benz, Carina; Mittelmark, Maurice; Vaandrager, Lenneke

    2014-01-01

    Aaron Antonovsky wrote extensively, although disjointedly, about the roles of culture in salutogenesis. This paper provides a synopsis of his work in this arena. A literature review identified those of his English language writings in which culture was a subject, and relevant text segments were analysed using an inductive followed by a deductive method. Using thematic network analysis, text segments were sorted inductively by open coding and then analysed. This was followed by deductive text segment coding guided by the constructs of the salutogenic model of health. The analysis revealed that Antonovsky had an expansive interest in the roles of culture in salutogenesis. His writings included attention to the role of culture in: (a) shaping life situations; (b) giving rise to stressors and resources; (c) contributing to life experiences of predictability, load balance and meaningful roles; (d) facilitating the development of the sense of coherence and (e) shaping perceptions of health and well-being. Antonovsky’s writings about culture were sometimes conjectural, as well as being obviously influenced by his life experience in the USA and then in Israel, and by the spirit of the times in which he lived. However, he also drew extensively on his own and others’ empiricism, leading him to view culture as an integral aspect of the salutogenic model of health. The present analysis provides salutogenesis scholars with a roadmap of Antonovsky’s reflections, ponderings and conclusions about culture in the context of salutogenesis. It provides assistance in the form of an overview of Antonovsky’s treatment of culture in the context of salutogenesis. PMID:24814861

  2. Compositional zoning of the bishop tuff

    USGS Publications Warehouse

    Hildreth, W.; Wilson, C.J.N.

    2007-01-01

    Compositional data for >400 pumice clasts, organized according to eruptive sequence, crystal content, and texture, provide new perspectives on eruption and pre-eruptive evolution of the >4600 km3 of zoned rhyolitic magma ejected as the BishopTuff during formation of Long Valley caldera. Proportions and compositions of different pumice types are given for each ignimbrite package and for the intercalated plinian pumice-fall layers that erupted synchronously. Although withdrawal of the zoned magma was less systematic than previously realized, the overall sequence displays trends toward greater proportions of less evolved pumice, more crystals (0-5 24 wt %), and higher FeTi-oxide temperatures (714-818??C). No significant hiatus took place during the 6 day eruption of the BishopTuff, nearly all of which issued from an integrated, zoned, unitary reservoir. Shortly before eruption, however, the zoned melt-dominant portion of the chamber was invaded by batches of disparate lower-silica rhyolite magma, poorer in crystals than most of the resident magma but slightly hotter and richer in Ba, Sr, andTi. Interaction with resident magma at the deepest levels tapped promoted growth ofTi-rich rims on quartz, Ba-rich rims on sanidine, and entrapment of near-rim melt inclusions relatively enriched in Ba and CO2.Varied amounts of mingling, even in higher parts of the chamber, led to the dark gray and swirly crystal-poor pumices sparsely present in all ashflow packages. As shown by FeTi-oxide geothermometry, the zoned rhyolitic chamber was hottest where crystal-richest, rendering any model of solidification fronts at the walls or roof unlikely.The main compositional gradient (75-195 ppm Rb; 0.8-2.2 ppm Ta; 71-154 ppm Zr; 0.40-1.73% FeO*) existed in the melt, prior to crystallization of the phenocryst suite observed, which included zircon as much as 100 kyr older than the eruption.The compositions of crystals, though themselves largely unzoned, generally reflect magma temperature and

    Ideal terrestrial analogues to Mars combine known features such as an arid environment, cold climate, deep water table, saline pore waters, and bedrock dominated by igneous or clastic sedimentary units. Terrestrial analogues best suited for calibrating a suite of planetary geophysical instruments, especially radar sounders, need to be sufficiently characterized to provide an accurate understanding of the local geologic context. The Bishop Tuff, Bishop, California is one of a number of recommended Mars analogue sites (National Research Council Decadal Study report on Terrestrial Analogues to Mars, 2001). While not cold, the Volcanic Tableland is situated in an arid environment, and is underlain by a relatively deep water table (100 to 180 m). These factors, combined with availability of detailed characterization data, made this a potentially appealing location in east-central California for testing the performance of existing and planned radar sounders for future Mars exploration. To take advantage of potential synergies that support improved subsurface resolution when applying multiple geophysical techniques, we developed a collaboration to mutually benefit from coordination of field and laboratory activities. Transient electromagnetic (TEM) soundings at several locations on the Volcanic Tableland were performed in preparation for potential ground-penetrating radar (GPR) investigations, and are documented in this paper. Laboratory data from Bishop Tuff samples, determined using capacitive cells in the frequency range of 1 to 1000 MHz, are also presented to assess the dielectric behavior of the local geologic units. Interpretation of geophysical data resulting from this field study is aided significantly by the wide range of geological, structural, and hydrogeological data collected by our team over the last 8 years. Knowledge about the subsurface electrical conductivity structure, determined through application of TEM, is used to quantify the expected magnitude of

  14. Do the bishops have it right on health care reform?

    PubMed

    Sulmasy, Daniel P

    1996-01-01

    The National Conference of Catholic Bishops has argued for significant government involvement in health care in order to assure respect for what they regard as the right to health care. Critics charge that the bishops are wrong because health care is not a right. In this article, it is argued that these critics are correct in their claim that health care is not a right. However, it is also argued that the premise that health care is not a right does not imply that the market is the most equitable and just system for providing health care. Natural law arguments in the tradition of Roman Catholic social teaching lead to the conclusion that a just and prosperous society has a moral obligation to provide health care even if there is no such right. Further, there are strong moral grounds for concluding that the bishops are correct in their claim that health care ought not to be considered a market commodity. It is argued that if health care ought not to be considered a commodity, then national health insurance is the best available alternative for fulfilling the social obligation to distribute health care resources justly and fairly at this time in American history. The bishops' case for government involvement can be made on the strength of the Catholic tradition in theological argumentation, independent of the claim that health care is a right.

  15. Electron-Molecule Col1isions: Quantitative Approaches, and the Legacy of Aaron Temkin

    NASA Technical Reports Server (NTRS)

    Schneider, B.I.

    2007-01-01

    This article, on electron-molecule collisions, is dedicated to the legacy of my good friend and sometime collaborator, Aaron Temkin on his retirement from the NASA-Goddard Space Flight Center after many years of work at the highest intellectual level in the theoretical treatment of electron-atom and electron-molecule scattering. Aaron's contributions to the manner in which we think about electron-molecule collisions is clear to all of us who have worked in this field. I doubt that the great progress that has occurred in the computational treatment of such complex collision problems could have happened without these contributions. For a brief historical account, see the discussion of Temkin's contribution to electron-molecule scattering in the first article of this volume by Dr. A. K. Bhatia. In this article, I will concentrate on the application of the so called, non-adiabatic R-matrix theory, to vibrational excitation and dissociative attachment, although I will also present some results applying the Linear Algebraic and Kohn-Variational methods to vibrational excitation. As a starting point for almost all computationally effective approaches to electron-molecule collisions, is the fixed nuclei approximation. That is, one recognizes, just as one does with molecular bound states, that there is a separation of electronic(fast) and nuclear(s1ow) degrees of freedom. This separation makes it possible to "freeze" the nuclei in space, calculate the collision parameters for the frozen molecule and then, somehow to add back the vibrations and rotations. The manner in which this is done, depends on the details of the collision problem. It is the work of Aaron and a number of other researchers that has provided the guidance necessary to resolve these issues.

    In this work, we investigate relationships between Darboux and type-2 Bishop frames in Euclidean space. Then, we obtain the geodesic curvature of the spherical image curve of the Darboux vector of the type-2 Bishop frame. Also, we give transition matrix between the Darboux and type-2 Bishop frames of the type-2 Bishop frames of the spherical images of the edges N→1,N→2 and b→. Finally, we express some interesting relations and illustrate of the examples by the aid Maple programe.

    2008-03-01

    This presentation details aspects of the rapid development of the connection between the dynamics of double strand DNA, and experimental findings that has occurred in the recent years. We will approach this topic by demonstrating the Peyrard-Bishop-Dauxois model's ability to provide useful insight on several experimental observations. Specifically, we will discuss the melting behavior of various DNA sequences, and mechanical unzipping through dynamic force spectroscopy. Focusing on viral transcription initiation we will further show how the connection between DNA dynamics and DNA's biological functionality is becoming increasingly strong. Finally, we will describe a probable connection between DNA dynamics and the ability of repair proteins to recognize UV-radiation damages.

    Anisotropy of magnetic susceptibility (AMS) and characteristic remanence were measured for 45 sites in the 0.76 Ma Bishop tuff, eastern California. Thirty-three sites were sampled in three stratigraphic sections, two in Owens gorge south of Long Valley caldera, and the third in the Adobe lobe north of Long Valley. The remaining 12 sites are widely distributed, but of limited stratigraphic extent. Weakly indurated, highly porous to dense, welded ash-flow tuffs were sampled. Saturation magnetization vs temperature experiments indicate two principal iron oxide phases: low Ti magnetites with 525 570 °C Curie temperatures, and maghemite with 610° 640 °C Curie temperatures. AF demagnetization spectra of isothermal remanent magnetizations are indicative of magnetite/maghemite predominantly in the multidomain to pseudo-single domain size ranges. Remeasurement of AMS after application of saturating direct fields indicates that randomly oriented single-domain grains are also present. The degree of anisotropy is only a few percent, typical of tuffs. The AMS ellipsoids are oblate with Kmin axes normal to subhorizontal foliation and Kmax axes regionally aligned with published source vents. For 12 of 16 locality means, Kmax axes plunge sourceward, confirming previous observations regarding flow sense. Topographic control on flow emplacement is indicated by the distribution of tuff deposits and by flow directions inferred from Kmax axes. Deposition east of the Benton range occurred by flow around the south end of the range and through two gaps (Benton notch and Chidago gap). Flow down Mammoth pass of the Sierra Nevada is also evident. At least some of the Adobe lobe in the northeast flowed around the west end of Glass mountain. Eastward flow directions in the upper Owens gorge and southeast directions in the lower Owens gorge are parallel to the present canyon, suggesting that the present drainage has been established along the pre-Bishop paleodrainage.

    It is not always possible to achieve a successful induction. Bishop scoring system is an efficient method used in determining whether the induction will be effective or not. The aim of this study was to train midwives on the benefits and use of the Bishop scoring system and to minimize the unnecessary use of induction. This study was conducted as pretest-posttest quasi-experimental design. This study was conducted in a maternity hospital in Erzurum between 01 February and 31 July 2012. In the study, the midwives received training on the use of the Bishop scoring system, and changes in their knowledge levels and application during practice of induction were then evaluated. While only 20% of midwives were using the Bishop score before the training, 56.7% started to use this tool after the training. Comparing the examinations performed on pregnant women by the midwives in the pre-induction period before and after the training, the mean of the Bishop score changed from 7.26 to 9.68 after the training. It was determined that the training could increase the knowledge levels of midwives regarding the Bishop scoring system and their attention paid to the Bishop scoring system in the practice of induction.

  8. Aaron T. Beck's drawings and the psychoanalytic origin story of cognitive therapy.

    PubMed

    Rosner, Rachael I

    2012-02-01

    In this essay the author challenges the standard origin story of cognitive therapy, namely, that its founder Aaron T. Beck broke with psychoanalysis to pursue a more pragmatic, parsimonious, and experimentalist cognitive model. It is true that Beck broke with psychoanalysis in large measure as a result of his experimental disconfirmation of key psychoanalytic ideas. His new school of cognitive therapy brought the experimental ethos into every corner of psychological life, extending outward into the largest multisite randomized controlled studies of psychotherapy ever attempted and inward into the deepest recesses of our private worlds. But newly discovered hand-sketched drawings from 1964 of the schema, a conceptual centerpiece of cognitive therapy, as well as unpublished personal correspondence show that Beck continued to think psychoanalytically even after he broke with psychoanalysis. The drawings urge us to consider an origin story much more complex than the one of inherited tradition. This new, multifaceted origin story of cognitive therapy reaches beyond sectarian disagreements and speaks to a broader understanding of the theoretical underpinnings of cognitive therapy.

  9. The bishop tuff: New insights from eruptive stratigraphy

    The 0.76 Ma Bishop Tuff, from Long Valley caldera in eastern California, consists of a widespread fall deposit and voluminous partly welded ignimbrite. The fall deposit (F), exposed over an easterly sector below and adjacent to the ignimbrite, is divided into nine units (F1-F9), with no significant time breaks, except possibly between F8 and F9. Maximum clast sizes are compared with other deposits where accumulation rates are known or inferred to estimate an accumulation time for F1-F8 as ca. 90 hrs. The ignimbrite (Ig) is divided into chronologically and/or geographically distinct packages of material. Earlier packages (Ig1) were emplaced mostly eastward, are wholly intraplinian (coeval with fall units F2-F8), lack phenocrystic pyroxenes, and contain few or no Glass Mountain-derived rhyolite lithic fragments. Later packages (Ig2) were erupted mostly to the north and east, are at least partly intraplinian (interbedded with fall unit F9 to the east), contain pyroxenes, and have lithic fractions rich in Glass Mountain-derived rhyolite or other lithologies exposed on the northern caldera rim. Recognition of the intraplinian nature of Ig1 east of the caldera and use of the fall deposit chronometry yields accumulation estimates of ca. 25 hrs for an earlier, less-welded subpackage and ca. 36 hrs for a later, mostly welded subpackage. Average accumulation rates range up to ???1 mm/s of densewelded massive ignimbrite, equivalent to ???2.5 mm/s of non-welded material. Comparisons of internal stratification in Ig1 and northern Ig2 lobes suggest the thickest northern ignimbrite accumulated in ???35 hrs. Identifiable vent positions migrated from an initial site previously proposed in the south-central part of the caldera (F1-8, Ig1) in complex fashion; one vent set (for eastern Ig2) migrated east and north toward Glass Mountain, while another set (for northern Ig2) opened from west to east across the northern caldera margin.

    The 650 km3 rhyolitic Bishop Tuff (eastern California, USA), which is stratigraphically zoned with respect to temperatures of mineral equilibration, reflects a corresponding thermal gradient in the source magma chamber. Consistent with previous work, application of the new TitaniQ (Ti-in-quartz) thermometer to quartz phenocryst rims documents an ???100 ??C temperature increase with chamber depth at the time of eruption. Application of TitaniQ to quartz phenocryst cores, however, reveals lower temperatures and an earlier gradient that was less steep, with temperature increasing with depth by only ???30 ??C. In many late-erupted crystals, sharp boundaries that separate low-temperature cores from high-temperature rims cut internal cathodoluminescent growth zoning, indicating partial phenocryst dissolution prior to crystallization of the high-temperature rims. Rimward jumps in Ti concentration across these boundaries are too abrupt (e.g., 40 ppm across a distance of <10 ??m) to have survived magmatic temperatures for more than ???100 yr. We interpret these observations to indicate heating-induced partial dissolution of quartz, followed by growth of high-temperature rims (made possible by lowering of water activity due to addition of CO2) within 100 yr of the climactic 760 ka eruption. Hot mafic melts injected into deeper parts of the magma system were the likely source of heat and CO2, raising the possibility that eruption and caldera collapse owe their origin to a recharge event. ?? 2007 Geological Society of America.

    Isaac Aaron (1804 to 1877), an ambitious young medical practitioner, arrived in Sydney from Britain in 1838 and was registered by the New South Wales Medical Board the following year. After contributing to the Australian Medical Journal, established in August 1846 by William Baker, he became the editor in December and acquired it in May the following year. Dr Pugh became the most prolific local contributor to the journal but he and the editor had a somewhat 'prickly' relationship. Aaron was very critical of etherisation when the first news arrived in Australia, but Pugh chose Aaron's journal in which to report his initial and subsequent experience with the technique. Aaron repeatedly appealed for experimental evidence and rational decision-making to determine the place of etherisation in medical practice. Unfortunately for Australian medicine, Aaron had to suspend the publication of the journal in October 1847, lacking both time and the support of the profession necessary to maintain it. This created an unanticipated adverse outcome for Dr Pugh.

  12. Physical and Thermal Structure of the Bishop Tuff, California

    2001-12-01

    The 0.76 Ma Bishop Tuff, California, includes an ignimbrite constructed from a series of overlapping packages of material erupted sequentially and simultaneously from multiple sources around the ring fracture of Long Valley caldera (Wilson, C.J.N., Hildreth, W., 1997, Journal of Geology 105, 407-439). Exceptionally good continuous exposures of the ignimbrite in the walls of Owens Gorge to the east of Long Valley provide a cross-section through the east-side packages (Ig1E and Ig2E). We have measured 10 sections up the gorge walls to draw up a cross section of the ignimbrite down Owens Gorge, using lithic abundances and lithologies to define the physical eruptive packages and their subdivisions, and measurements of tuff bulk density (as an easily measured proxy for welding intensity) to define the thermal eruptive packages. The physically emplaced bodies of ignimbrite represent an overlapping, shingling suite of material such that successively later ignimbrite occurs most prominently farther away from source. Two major and two lesser zones of maximum density (welding) are present, the lower two (in Ig1Ea and lower Ig1Eb) in upper Owens Gorge, and the two most prominent (upper Ig1Eb and Ig2Eb) in middle and lower parts of the gorge. Welding fluctuations are controlled by bulk temperatures of individual batches of hotter and cooler material, but the intensity of the welding also depends on deposit thickness (i.e. load stress). Physically defined contacts between ignimbrite packages show that time breaks inferred to be of hours may not result in formation of any visible parting or flow unit boundary. Furthermore, positions of density (welding) minima between zones of higher density tuff do not coincide with horizons of stratigraphic significance. These observations lead to two conclusions. (1) The absence of clear partings or flow unit boundaries in an ignimbrite sequence is not diagnostic either of the material representing a single flow unit, or of the material being

    The Bishop Tuff of eastern California is the type example of a high-silica rhyolite that, according to Hildreth, supposedly evolved by liquid-state differentiation. New analyses establish that the Bishop Tuff "earlyllate" rare earth element trend reported by Hildreth mimics the relations between groundmass glasses and whole rocks for allanite-bearing pumice. Differences in elemental concentrations between whole rock and groundmass are the result of phenocryst precipitation; thus the data of Hildreth are precisely those expected to result from crystal fractionation.

From Oct 1986 to Dec 1988, 242 cases of primiparae by this method and the latent period in physiological limit. This is a great breakthrough in induced labour for gravidae with low Bishop's scores. We found that this method is simple, effective, safe, and economic. It not only alleviates pain of the gravidae, but also helps to prevent the rise of caesarean section rate.

    2015-01-01

    Purpose of Review: Executive functions represent a constellation of cognitive abilities that drive goal-oriented behavior and are critical to the ability to adapt to an ever-changing world. This article provides a clinically oriented approach to classifying, localizing, diagnosing, and treating disorders of executive function, which are pervasive in clinical practice. Recent Findings: Executive functions can be split into four distinct components: working memory, inhibition, set shifting, and fluency. These components may be differentially affected in individual patients and act together to guide higher-order cognitive constructs such as planning and organization. Specific bedside and neuropsychological tests can be applied to evaluate components of executive function. While dysexecutive syndromes were first described in patients with frontal lesions, intact executive functioning relies on distributed neural networks that include not only the prefrontal cortex, but also the parietal cortex, basal ganglia, thalamus, and cerebellum. Executive dysfunction arises from injury to any of these regions, their white matter connections, or neurotransmitter systems. Dysexecutive symptoms therefore occur in most neurodegenerative diseases and in many other neurologic, psychiatric, and systemic illnesses. Management approaches are patient specific and should focus on treatment of the underlying cause in parallel with maximizing patient function and safety via occupational therapy and rehabilitation. Summary: Executive dysfunction is extremely common in patients with neurologic disorders. Diagnosis and treatment hinge on familiarity with the clinical components and neuroanatomic correlates of these complex, high-order cognitive processes. PMID:26039846

    Peter of Tilleberi (Tilbury), later known as bishop Thomas of Wroclaw, after completing his studies (in Bologna or in Montpellier) worked as a physician in northern Italy and probably in Spain. Later through Germany and Bohemia, he came to Wroclaw in 1336 where he joined the Order of St. Dominic. In 1352, Thomas was made an auxiliary bishop of the diocese of Wroclaw. After the episcopal consecration, Thomas stopped living in the abbey, but all the time he was well known both as a priest and physician. He is known as an author of several treatises on medical sciences. His most important work entitled Michi competit (i.e. It suits me) is composed of four parts: Regimen sanitatis (i.e. Hygiene), Aggregatum (i.e. Aggregation), Antidotarium (i.e. Medicine directory) and Practica medicinalis (i.e. Medical practices). Moreover, he is the author of other treatises including, for example, De phlebotomia et de iudiciis cruoris (i.e. On phlebotomy and blood content) and De urinis (i.e. On urine). Some Polish scientists claim that bishop Thomas of Wroclaw with his knowledge and industriousness functioned as a university faculty of medicine even though the University of Cracow had not been established yet.

    1995-01-01

    The Bishop Tuff, a Quaternary high-silica rhyolite in east-central California, is widely considered the type example of a vertically and monotonically zoned pyroclastic deposit that represents zoning in the source magma reservoir, inverted during the process of pyroclastic emplacement. However, the deposit of plinian pumice, which forms the base of the Bishop Tuff and represents the initial 10% or so of all magma erupted during the event that produced the Bishop Tuff, contains features at odds with monotonic zoning for the reservoir. Relative to overlying ignimbrite, the plinian deposit contains a reversal in trace-element zoning. The data have been previously interpreted as due to processes of chemical fractionation and evolution operating within a magma system closed to chemical interactions with its roof rocks. However, it is suggested here that the reversed zoning and other above-noted features can be explained equally well as consequences of minor assimilation of roof rocks into a magma reservoir that was erupted from the top down. -from Authors

    The Bishop Tuff is a giant silicic ignimbrite erupted at 0.76 Ma in eastern California, USA. Five pumice clasts from the late-erupted Bishop Tuff (Aeolian Buttes) were studied in an effort to better understand the pre- and syn-eruptive history of the Bishop magma body and place constraints on the timescales of its existence. This study complements and expands on a previous study that focused on early-erupted Bishop Tuff pumice clasts. Bulk densities of pumice clasts were measured using an immersion method, and phenocryst crystal contents were determined using a sieving and winnowing procedure. X-ray tomography was used to obtain qualitative and quantitative textural information, particularly crystal size distributions (CSDs). We have determined CSDs for crystals ranging in size from {approx}10 to {approx}1000 {micro}m for three groups of mineral phases: magnetite ({+-}ilmenite), pyroxene + biotite, quartz + feldspar. Similar to early-erupted pumice, late-erupted pumice bulk density and crystal contents are positively correlated, and comparison of crystal fraction vs size trends suggests that the proportion of large crystals is the primary control on crystallinity. Porosity is negatively correlated with crystal content, which is difficult to reconcile with closed-system crystallization. Magnetite and pyroxene + biotite size distributions are fractal in nature, often attributed to fragmentation; however, crystals are mostly whole and euhedral, such that an alternative mechanism is necessary to explain these distributions. Quartz + feldspar size distributions are kinked, with a shallow-sloped log-linear section describing large crystals (> 140 {micro}m) and a steep-sloped log-linear section describing small crystals (< 140 {micro}m). We interpret these two crystal populations as resulting from a shift in crystallization regime. We suggest that the shallow-sloped section describes a pre-eruptive quartz + feldspar growth-dominated regime, whereas the steep

    We present field observations of erosional columns in the Bishop Tuff and then use laboratory results and numerical models to argue that these columns are evidence of relict convection in a cooling ignimbrite. Many square kilometers of the Bishop Tuff have evenly-spaced, vertical to semi-vertical erosional columns, a result of hydrothermal alteration. These altered regions are more competent than the surrounding tuff, are 0.1-0.7 m in diameter, are separated by ~ 1 m, and in some cases are more than 8 m in height. JE Bailey (U. of Hawaii, dissertation, 2005) suggested that similar columns in the Bandelier Tuff were formed when slumping allowed water to pool at the surface of the still-cooling ignimbrite. As water percolated downward it boiled generating evenly spaced convection cells similar to heat pipes. We quantify this conceptual model and apply it the Bishop Tuff to understand the physics within ignimbrite-borne hydrothermal systems. We use thin sections to measure changing porosity and use scanning electron microscope (SEM) and x-ray diffraction (XRD) analyses to show that pore spaces in the columns are cemented by the mineral mordenite, a low temperature zeolite that precipitates between 120-200 oC (Bish et al., 1982), also found in the Bandelier Tuff example. We then use scaling to show 1) that water percolating into the cooling Bishop Tuff would convect and 2) that the geometry and spacing of the columns is predicted by the ignimbrite temperature and permeability. We use the computer program HYDROTHERM (Hayba and Ingebritsen, 1994; Kipp et al., 2008) to model 2-phase convection in the Bishop Tuff. By systematically changing permeability, initial temperature, and topography we can identify the pattern of flows that develop when the ignimbrite is cooled by water from above. Hydrothermally altered columns in ignimbrite are the natural product of coupled heat, mass, and chemical transport and have similarities to other geothermal systems, economic ore deposits

    Zircon crystals offer a unique combination of suitability for high-precision radiometric dating and high resistance to alteration. Paleomagnetic experiments on ancient zircons may potentially constrain the history of the earliest geodynamo, which would hold broad implications for the early Earth's interior and atmosphere. However, the ability of zircons to record accurately the geomagnetic field has not been demonstrated. Here we conduct thermal and alternating field (AF) paleointensity experiments on 767.1 thousand year old (ka) zircons from the Bishop Tuff, California. The rapid emplacement of these zircons in a well-characterized magnetic field provides a high-fidelity test of the zircons' intrinsic paleomagnetic recording accuracy. Successful dual heating experiments on eleven zircons measured using a superconducting quantum interference device (SQUID) microscope yield a mean paleointensity of 54.1 ± 6.8μT (1σ; 42.6 ± 5.3μT after excluding possible maghemite-bearing zircons), which is consistent with high-precision results from Bishop Tuff whole rock (43.0 ± 3.2μT). High-resolution quantum diamond magnetic (QDM) mapping, electron microscopy, and X-ray tomography indicate that the bulk of the remanent magnetization in Bishop Tuff zircons is carried by Fe oxides associated with apatite inclusions, which may be susceptible to destruction via metamorphism and aqueous alteration in older zircons. As such, while zircons can reliably record the geomagnetic field, robust zircon-derived paleomagnetic results require careful characterization of the ferromagnetic carrier and demonstration of their occurrence in primary inclusions. We further conclude that a combination of quantum diamond magnetometry and high-resolution imaging can provide detailed, direct characterization of the ferromagnetic mineralogy of geological samples.

Core EFs are inhibition [response inhibition (self-control—resisting temptations and resisting acting impulsively) and interference control (selective attention and cognitive inhibition)], working memory, and cognitive flexibility (including creatively thinking “outside the box,” seeing anything from different perspectives, and quickly and flexibly adapting to changed circumstances). The developmental progression and representative measures of each are discussed. Controversies are addressed (e.g., the relation between EFs and fluid intelligence, self-regulation, executive attention, and effortful control, and the relation between working memory and inhibition and attention). The importance of social, emotional, and physical health for cognitive health is discussed because stress, lack of sleep, loneliness, or lack of exercise each impair EFs. That EFs are trainable and can be improved with practice is addressed, including diverse methods tried thus far. PMID:23020641

    Objectives: To compare the value of transvaginal ultrasonographic measurement of the cervical length versus the Bishop score, prior to induction of labour, in predicting the mode of delivery within four days. Materials and Methods: This longitudinal study included 110 women (at term, singleton, vertex presentation) in whom induction of labour was performed at 37-42 weeks of gestation. Cervical length on transvaginal ultrasound and the Bishop score were assessed prior to induction according to standard protocol. Medical records were reviewed for relevant demographic and clinical data. Primary outcome criterion was successful vaginal delivery within 96 h. Univariate analyses and receiver operating characteristic (ROC) curves were used to examine differences between variables possibly predicting outcome. Results: Of the 110 women 66 were nulliparous and 44 multiparous. Vaginal delivery within 96 h was successful in 48 (73%) nulliparous and in 40 (91%) multiparous women ( i.e. in 80% of the total population). The overall rate of caesarean delivery was 17%. There was a significant difference between nulliparous and multiparous women in age, cervical length (mean in mm in nulliparous women: 29.31, range: 5.00-56.00; in multiparous women: 37.04, range: 12.00-56.00), Bishop score and successful induction, but no significant difference between these subgroups in neonatal outcomes. Only the Bishop score in nulliparous women showed a significant relationship between this variable and predicting successful labour induction (area under the ROC curve 0.679; standard error 0.73; p < 0.05; 95% CI: 0.536-0.823). The best cut-off value for the Bishop score was 3, with a sensitivity of 56.3% and a specificity of 72.2%. Conclusion: In this study group significant independent prediction of vaginal delivery within 96 h is provided by the Bishop score but only in nulliparous women. Transvaginal ultrasonographic measurement of cervical length is not a significant independent predictor

    Does a religion shape belief-related decisions and influence neural processing? We investigated an eminent bishop of the Catholic Church in Germany by using functional magnetic resonance imaging (fMRI) to assess neural processing while he was responding to short sentences of the Christian Bible, the Islamic Quran, and the Daodejing ascribed to Laozi in Experiment 1. In Experiment 2, continuous praying was further compared to the resting state activity. In contrast to explicit statements of agreeing or not agreeing to different statements from the Bible and the Quran, we found in Experiment 1 no difference in neural activation when the bishop was reading these statements from the two religions. However, compared to reading statements from the Bible, reading statements from the Daodejing resulted in significantly higher activation in the left inferior and middle frontal cortices and the left middle temporal gyrus, although he equally agreed to both statements explicitly. In Experiment 2, no difference during continuous praying and the resting state activity was observed. Our results confirm the difference between explicit and implicit processing, and they suggest that a highly religious person may pray always-or never. On a more general level this observation suggests that ritualized activities might be subliminally represented in resting state activities.

    Supereruptions violently transfer huge amounts (100 s-1000 s km(3)) of magma to the surface in a matter of days and testify to the existence of giant pools of magma at depth. The longevity of these giant magma bodies is of significant scientific and societal interest. Radiometric data on whole rocks, glasses, feldspar and zircon crystals have been used to suggest that the Bishop Tuff giant magma body, which erupted ~760,000 years ago and created the Long Valley caldera (California), was long-lived (>100,000 years) and evolved rather slowly. In this work, we present four lines of evidence to constrain the timescales of crystallization of the Bishop magma body: (1) quartz residence times based on diffusional relaxation of Ti profiles, (2) quartz residence times based on the kinetics of faceting of melt inclusions, (3) quartz and feldspar crystallization times derived using quartz+feldspar crystal size distributions, and (4) timescales of cooling and crystallization based on thermodynamic and heat flow modeling. All of our estimates suggest quartz crystallization on timescales of <10,000 years, more typically within 500-3,000 years before eruption. We conclude that large-volume, crystal-poor magma bodies are ephemeral features that, once established, evolve on millennial timescales. We also suggest that zircon crystals, rather than recording the timescales of crystallization of a large pool of crystal-poor magma, record the extended periods of time necessary for maturation of the crust and establishment of these giant magma bodies.

    Binocular eye movements were measured while subjects perceived the wallpaper illusion in order to test the claim made by Bishop Berkeley in 1709 that we perceive the distance of nearby objects by evaluating the vergence angles of our eyes. Four subjects looked through a nearby fronto-parallel array of vertical rods (28-35 cm away) as they binocularly fixated a point about 1 meter away. The wallpaper illusion was perceived under these conditions, i.e. the rods appeared farther away than their physical location. We found that although binocular fixation at an appropriate distance was needed to begin perceiving the wallpaper illusion (at least for naive observers), once established, the illusion was quite robust in the sense that it was not affected by changing vergence. No connection between the apparent localization of the rods and vergence was observed. We conclude that it is unlikely that vergence, itself, is responsible for the perceived distance shift in the wallpaper illusion, making it unlikely that vergence contributes to the perception of distance as Bishop Berkeley suggested. We found this to be true even when vergence angles were relatively large (more than 2 deg), the region in which the control of vergence eye movements has been shown to be both fast and effective.

    We present the first results from a project whose goal is to advance our basic understanding of the role that fog and persistent stratus clouds play in ecological processes in the California Channel Islands. Our work is focused on a population of Bishop Pines (Pinus muricata) on Santa Cruz Island (SCI), the largest, most topographically complex and most biologically diverse island along the California coast. This is the southernmost population (except for an outlier stand near San Vicente, Baja California), and tree growth appears to be water-limited in such a marginal habitat. We hypothesize that persistent fog and low stratus clouds enhance the water balance of these trees via direct water inputs (fog drip and foliar absorption) and reduced solar heating. To assess these possible effects, we have established weather stations and fog and rain collectors throughout the largest Bishop pine stand on SCI. Initial analysis of weather data shows dramatic differences in solar loading over short distances. We present data on the isotopic content (oxygen-18 and hydrogen-2) of water samples collected from winter 2003 to summer 2004. The samples we collected include fogwater, rainfall, water vapor, soil water, leaf and xylem water, and stream water. We also collected and analyzed leaf biomass and soil organic matter samples at periodic intervals for carbon-13 content. These latter data are evaluated in light of extensive leaf-level ecophysiological data collected in the field and as part of a parallel greenhouse study.

    Energy Flow Analysis (EFA) has been developed to predict the vibrational energy density of the system structures in the medium-to-high frequency range. The elementary longitudinal wave theory is often used to describe the longitudinal vibration of a slender rod. However, for relatively large diameter rods or high frequency ranges, the elementary longitudinal wave theory is inaccurate because the lateral motions are not taken into account. In this paper, vibrational energy flow models are developed to analyze the longitudinally vibrating Rayleigh-Love rod considering the effect of lateral inertia, and the Rayleigh-Bishop rod considering the effect not only of the lateral inertia but also of the shear stiffness. The derived energy governing equations are second-order differential equations which predict the time and space averaged energy density and active intensity distributions in a rod. To verify the accuracy of the developed energy flow models, various numerical analyses are performed for a rod and coupled rods. Also, the EFA results for the Rayleigh-Love and Rayleigh-Bishop rods are compared with the analytical solutions for these models, the traditional energy flow solutions, and the analytical solutions for the classical rod.

    The Bishop Tuff (California), which erupted at 760 ka and formed the Long Valley caldera, is the archetypical example of a thermally and compositionally stably stratified giant magma body. The deposit includes only high-silica rhyolite, but it is zoned with an early-erupted, pyroxene-free, crystal-poor (5-20 wt. % crystals) lower unit (EBT) and a late-erupted, pyroxene-bearing, more crystal-rich (5-30 wt. % crystals) upper unit (LBT). Gradients in composition and temperature within the magma body were first inferred by Hildreth (1979): Fe-Ti oxide thermometry reveals a gradient in pre-eruptive temperatures from EBT to LBT, suggesting thermal stratification; and the homogeneity of phenocryst compositions within each pumice clast suggests stable compositional stratification. This view of the Bishop magma body - the Standard Model - has remained largely unchallenged by subsequent work; we present new pre-eruptive temperature (T) and pressure (P) estimates to critically assess its viability. The pinnacle of the Standard Model is the gradient in pre-eruptive T and fO2 inferred from Fe-Ti oxides. Fe-Ti oxides also constrain TiO2 activity in the melt (Ghiorso & Gualda, CMP, in press); the positive correlation between T and aTiO2 observed in the Bishop dataset cannot be explained by magmatic crystallization, and comparison with aTiO2 from rhyolite-MELTS shows that Fe-Ti oxides were not in equilibrium with melt and do not record pre-eruptive conditions. We use zircon saturation temperatures calculated with literature glass inclusion data (Wallace et al., JGR, 1999; Anderson et al., JPet, 2000) to assess pre-eruptive temperatures; Zr contents in glass inclusions vary over a narrow interval (~70-110 ppm) for both EBT and LBT, yielding T between 720 and 755 °C for both, arguing against the inferred thermal stratification. Geobarometry should yield systematic differences between EBT and LBT. Published H2O-CO2 glass inclusion data yield overlapping P for EBT and LBT pumice

    A simple Langevin approach is used to study stationary properties of the Peyrard-Bishop-Dauxois model for DNA, allowing known properties to be recovered in an easy way. Results are shown for the denaturation transition in homogeneous samples, for which some implications, so far overlooked, of an analogy with equilibrium wetting transitions are highlighted. This analogy implies that the order parameter, asymptotically, exhibits a second-order transition even if it may be very abrupt for nonzero values of the stiffness parameter. Not surprisingly, we also find that, for heterogeneous DNA, within this model the largest bubbles in the premelting stage appear in adenine-thymine-rich regions, while we suggest the possibility of some sort of not strictly local effects owing to the merging of bubbles.

  2. Impact of fog-drip versus fog immersion on leaf-level function of Bishop pines

    Fog-water is known to be an important water source to plants in coastal, Mediterranean climates because it augments plant available water several months after the last winter rain, when conditions are otherwise warm and dry. While fog-drip to the soil surface is the most obvious contribution of fog to the water budget of an ecosystem, recent studies provide convincing evidence that foliar absorption of fog water is also possible. The focus of our research was to assess the relative importance of fog-drip and fog immersion on the photosynthetic capacity and gas exchange rates of a coastal pine species, Bishop pine (Pinus muricata, D.Don), a drought sensitive species restricted to the fogbelt of coastal California and offshore islands. We conducted a greenhouse study where we manipulated fog water inputs to potted Bishop pine saplings during a three-week dry-down period. Fifteen saplings were randomly assigned one of three treatments: 1) fog-drip and fog-immersion, 2) fog immersion alone, and 3) no fog water inputs. We artificially generated nighttime fog events using an ultrasonic device, which produces fog droplets. Given that the canopy architecture varied between saplings, we standardized the amount of fog-drip plants received by preventing direct fog drip from the canopy, and instead added the average amount of fog water that would have fallen from each canopy. To detect changes in soil moisture, we installed volumetric soil moisture probes in each pot at 2 and 10 cm depth. The plant response variables measured were photosynthetic capacity and maximum gas exchange rates of sapling trees. Our results show that plants which received both fog-drip and fog immersion sustained higher gas exchange rates and photosynthetic capacity through the dry-down period compared to trees in other treatment groups. Trees that received only fog immersion had lower rates of gas exchange and lower photosynthetic capacity relative to trees that received both fog-drip and fog immersion

  3. Characterizing Lacustrine Sediment that Records the Matuyama/Brunhes Polarity Transition at Bishop, California

    We are doing a study of the physical and chemical properties of exposed lacustrine sediment deposited in Pleistocene Owens Lake near Bishop, CA (37.3˚ N, 241.5˚ E) that was used in an investigation of the Matuyama/Brunhes (M/B) polarity transition (Liddicoat, 1993). The study complements one of similar lacustrine sediment that records the Mono Lake Excursion in the Mono Basin, CA (38.0˚ N, 240.8˚ E) where field strength (Coe and Liddicoat, 1994) and percentage of inorganic carbon seem to be contributing factors on the ability of magnetic grains to accurately record field direction when the field is changing rapidly. For instance, there is an inverse relationship between the percentage of total inorganic carbon (TIC) and the mobility of magnetic grains that preserve the remanence - the greater the percentage of TIC, the less likely grains become realigned when the field directions change (Spokowski et al., 2011). At Bishop, as in the Mono Basin, the sediment is unweathered fine- to medium-grain sand, silt, and volcanic ash from a nearby granitic (Sierra Nevada) and volcanic provenance (Lajoie, 1968), and the dominant magnetic mineral is magnetite (Liddicoat and Coe, 1979; Liddicoat, 1993). The Bishop Ash, dated by K/Ar at about 0.68 m.y. (Dalrymple et al., 1965), is in conformable contact with the lake sediments, which are exposed in the former bank of the Owens River. At Bishop we are using samples that record reverse (Matuyama), transitional, and normal (Brunhes) polarity that were demagnetized in an alternating field. The percentage of grains with a diameter less than 63 micrometers is about 40 percent in the reversely magnetized sediment and about 65 percent in the sediment that records transitional or normal polarity. These percentages differ somewhat from those in the Mono Basin where the percentage is about 80. The percentage of total organic carbon (TOC) does not exceed about 3 percent in the Owens Lake sediment and it is slightly less in the Mono Basin

  4. Volatile History of the Bishop Tuff from Apatite Phenocrysts and Inclusions

    Apatite is a common mineral found in a wide variety of volcanic rocks and contains all of the volatile elements within its structure as either major or minor components. Such characteristics make apatite a useful tool for developing a better understanding of complex magmatic systems and their evolution. For some elements, such as F, Cl, and OH, an apatite phenocryst can participate in chemical exchange within the magma chamber on very short timescales (Brenan, 1993, Chem. Geol.), thus giving insight into the volatiles in the system immediately prior to eruption. For other elements (including S), natural and experimental data indicate that variations can be preserved for longer timescales, potentially providing a different, yet equally interesting record. With an especially well-studied ignimbrite and air fall sequence and previously published melt inclusion work, the Bishop Tuff is an ideal system in which to test the utility of apatite crystals for studying volatile evolution of a large volume magma body. The Bishop Tuff has a nine unit air fall sequence (Wilson and Hildreth, 1997, 2003, J. Geol.) from which three units were chosen to represent early (unit #2), middle (#5), and late (#8) air fall periods. Along with apatite phenocrysts, apatite inclusions within zircon phenocrysts were used to investigate the prospect that a host could protect the crystal from volatile exchange with the melt in a manner analogous to melt inclusions. This would potentially extend the record deeper into the history of the magma. Fifty analyses of volatile, major, and trace elements were performed at UCLA using the JOEL JXA-8200 electron microprobe. Apatite phenocrysts from the Bishop Tuff are very poor in Cl with measured values (<200 ppm), often within error of zero. In these same crystals, we observe S-depleted rims (<2000 ppm) and S-rich cores (>4500 ppm), possibly representing an earlier magmatic phase, or xenocrystic remnants. Interestingly, we observe similar S variations in

    Supereruptions violently transfer huge amounts (100 s–1000 s km3) of magma to the surface in a matter of days and testify to the existence of giant pools of magma at depth. The longevity of these giant magma bodies is of significant scientific and societal interest. Radiometric data on whole rocks, glasses, feldspar and zircon crystals have been used to suggest that the Bishop Tuff giant magma body, which erupted ∼760,000 years ago and created the Long Valley caldera (California), was long-lived (>100,000 years) and evolved rather slowly. In this work, we present four lines of evidence to constrain the timescales of crystallization of the Bishop magma body: (1) quartz residence times based on diffusional relaxation of Ti profiles, (2) quartz residence times based on the kinetics of faceting of melt inclusions, (3) quartz and feldspar crystallization times derived using quartz+feldspar crystal size distributions, and (4) timescales of cooling and crystallization based on thermodynamic and heat flow modeling. All of our estimates suggest quartz crystallization on timescales of <10,000 years, more typically within 500–3,000 years before eruption. We conclude that large-volume, crystal-poor magma bodies are ephemeral features that, once established, evolve on millennial timescales. We also suggest that zircon crystals, rather than recording the timescales of crystallization of a large pool of crystal-poor magma, record the extended periods of time necessary for maturation of the crust and establishment of these giant magma bodies.

    The mid-Pleistocene Bishop Tuff (Long Valley, California) is one of the largest volume Quaternary volcanic eruptions and has been extensively studied for its physical and chemical characteristics. These data sets have resulted in the Bishop Tuff being described as an 'archetypal' magmatic system. It has also been the subject of multiple geochronological investigations, in particular due to its occurrence just above the Bruhnes-Matuyama geomagnetic reversal, but also for geochemical investigations of the longevity of magmatic systems and the determination of crystal residence times. Published ages for the BT using different isotopic systems and techniques are difficult to reconcile; for example SIMS Pb/U data sets have been interpreted to reflect zircon crystallization over a timescale of 105 years, with a mean crystallization date around 820 Ka, suggesting a protracted magmatic evolution. In contrast, TIMS Pb/U data suggests zircon crystallization over a much shorter period of time, interpreted to be less than 104 years, with the bulk of zircon crystallization occurring in the last few thousand years before eruption. Augmenting these problems are that some new 40Ar/39Ar sanidine dates are >10% older than the youngest population of zircon, yielding a physically impossible reversal of cooling (eruption) and crystallization ages. Here, we present new SHRIMP II U-Th-Pb data and TIMS single-grain and sub-grain analyses of zircon from the Bishop Tuff. Cathodoluminescence imaging reveals similar features described by others - featureless central regions bounded by sector and oscillatory zoned rims. For young zircon such as these, with radiogenic 206Pb concentrations below 0.5ppm, analyses are very sensitive to corrections to common Pb (either introduced in the lab or present as initial Pb in the zircon). The results of 37 single spot SHRIMP analyses, in which central portions of grains were targeted in order to capture the onset of zircon crytsallization, show a range of

  9. Investigating tree mortality at multiple spatial and temporal scales in the Bishop pine forest on Santa Cruz Island, California

    The rate of tree mortality has increased across the western United States in recent decades, and many studies attribute the cause to water stress induced by regional warming. To date, the geographical scope of study regions affected by widespread tree mortality in the American West has largely been limited to continental, montane climates. Much less is known about mortality events in other climatic regions, such as coastal forests. The relatively unvarying nature of the coastal, maritime climate has traditionally been assumed to buffer these forests from large climate variations; however, we have observed rapid tree mortality in this region which suggests coastal forests may be as susceptible to drought-induced mortality as inland forest locations. Santa Cruz Island (SCI), one of the California Channel Islands, harbors numerous relict and endemic plant species, including Bishop pine (Pinus muricata). Following extreme drought in southern California in two of the last three years (2007-2009), widespread mortality of Bishop pines has become evident. Bishop pine populations are restricted to the fog belt of coastal California and northern Baja California; therefore, a major reduction of existing populations on SCI would greatly reduce the distribution of the species as a whole. The focus of my research is to investigate the mechanisms underlying spatial and temporal patterns of Bishop pine mortality on SCI. I used remote sensing techniques to characterize spatiotemporal patterns of tree mortality and I have performed ground-data collection to validate remote-sensing results. Remote sensing in combination with field verification is a valuable tool to understand the spatiotemporal pattern of tree mortality and is a necessary step to help elucidate potential environmental and biological controls on tree mortality.

  10. Hybrid fall deposits in the Bishop Tuff, California: A novel pyroclastic depositional mechanism

    Hybrid fall deposits in the Bishop Tuff show features common to both archetypal fall and surge deposits. Like normal-fall deposits, they have an overall plane-parallel bedding and flat-lying pumice clasts but also, like surge deposits, they show variable development of cross-bedding, some crystal and pumice sorting, and some rounding of pumice clasts. All variations exist from normal-fall deposits, through streaky material with incipient development of cross-bedding, to the hybrid fall deposits with well-developed cross-bedding. The streaky and hybrid deposits are interpreted as fall material contemporaneously redeposited by strong (up to 40 m/s) swirling winds, comparable to firestorm whirlwinds, generated by air currents associated with coeval emplacement of pyroclastic flows. Recognition of hybrid fall deposits is important in interpreting the dynamics of explosive eruptions and correctly assessing volcanic hazards. However, although such deposits may be commonly produced by explosive eruptions, especially where pyroclastic flows accompany fall activity, they are likely to be overlooked, or wrongly interpreted as surge deposits or secondary, reworked material.

    The Bishop Tuff (USA) is a large-volume, high-silica pyroclastic rhyolite. Five pumice clasts from three early stratigraphic units were studied. Size distributions were obtained using three approaches: (1) crushing, sieving and winnowing (reliable for crystals >100 {micro}m); (2) microscopy of 1 mm{sup 3} fragments (preferable for crystals <100 {micro}m); and (3) computerised X-ray microtomography of {approx}1 cm{sup 3} pumice pieces. Phenocryst fragments coated with glass are common, and the size distributions for all crystals are concave-upward, indicating that crystal fragmentation is an important magmatic process. Three groups are recognised, characterised by: (1) high-density (0.759-0.902 g cm{sup -3}), high-crystal content (14.4-15.3 wt.%) and abundant large crystals (>800 {micro}m); concave-downward size distributions for whole crystals indicate late-stage growth with limited nucleation, compatible with the slow cooling of a large, gas-saturated, stably stratified magma body; (2) low-density (0.499 g cm{sup -3}), low-crystal content (6.63 wt.%) and few large crystals; the approximately linear size distribution reveals that nucleation was locally important, perhaps close to the walls; and (3) intermediate characteristics in all respects. The volumetric fraction of bubbles inversely correlates with the number of large crystals. This is incompatible with isobaric closed-system crystallisation, but can be explained by sinking of large crystals and rise of bubbles in the magma.

  12. Petrogenesis and volatile stratigraphy of the Bishop Tuff - evidence from melt inclusion analysis

    The preeruptive volatile gradient of the Bishop Tuff (BT) is determined on the basis of detailed analyses of the H2O, F, and Cl contents of melt inclusions in phenocrysts from different stratigraphic levels of the deposit. The magma which produced BT was found to be strongly zoned with respect to H2O, and slightly zoned with respect to F and B. The bulk of the volatile zonation within the BT magma was in the 120 cu km of magma which produced the Plinian tephra, where the H2O content decreases from a mean of 6 wt pct to a mean of 3.3 wt pct to between 2 and 3 wt pct for the magma which formed the ignimbrite. The strong H2O gradient suggests that only the magma from the very upper portion of the magma chamber could have been saturated with respect to an H2O-dominated vapor phase, because of the decrease in H2O contents with decreasing pressure. The volatile enrichment in the magma which formed the BT Plinian tephra appears to have occurred independently of strong trace element enrichment and may have been generated by rapid diffusion from a sidewall crystallization zone. 60 refs.

    A survey to assess techniques to control occupational exposure to formaldehyde (50000) and methanol (67561) was conducted at the Celanese Chemical Company (SIC-2819) formaldehyde production unit at Bishop, Texas, in October 1982. Occupational exposure to formaldehyde was expected to be low since the production process was isolated and enclosed, except for the process sample, and the loading and discharge points. Other control measures included water scrubbers on the formaldehyde storage tanks, enclosed ventilation systems, natural ventilation, and the use of personal protective equipment. The results of analysis of the formaldehyde samples were considered unreliable and were discarded. Breathing zone samples of methanol showed generally low concentrations. It was noted that since methanol was produced at the facility and the necessity of unloading trucks or rail cars was eliminated, a major source of methanol exposure was eliminated. The authors conclude that the workers are not overexposed to methanol on a short or long term basis. Due to the lack of analytical data, no conclusions concerning formaldehyde exposure could be drawn; however, engineering controls appear to be effective.

  14. Application of the Plagioclase-Liquid Hygrometer to the Bishop Tuff: Consistency with Melt Inclusion H2O Contents

    High-silica (74-77 wt% SiO2) rhyolites are the most evolved magmas on Earth and constitute some of the largest eruptions (1000s of km3). Of these, one classic example is the Bishop Tuff, a 760 ka eruption of >670 km3 of high-silica rhyolite erupted from Long Valley caldera, CA. Documenting dissolved H2O contents is crucial for understanding its origin and evolution. Analyses of water contents measured in quartz-hosted melt inclusions from the Bishop Tuff (Wallace et al. 1999; Anderson et al. 2000) show that the Early and Middle Bishop Tuff (Ig1Eb, Ig2Ea) have higher water contents (≤ 6.3 wt% H2O) than the Late Bishop Tuff (Ig2NWa; ≤ 5.2 wt%). Our work utilizes the revised plagioclase-liquid hygrometer (Waters & Lange, 2015), which is applicable to rhyolite, to evaluate internal consistency between Fe-Ti oxide temperatures, the plagioclase hygrometer, and melt inclusion H2O analyses. Two-oxide thermometry (Ghiorso & Evans, 2008), using all possible Fe-Ti oxide pairs (between 56 and 1500 pairs for individual samples), was carried out on 2-3 pumice clasts for each sampled eruptive unit. Resulting temperatures (°C ± 1σ) for individual clasts are: 705 ± 12, 728 ± 10 for unit Ig1Eb; 710 ± 12, 728 ± 11 for unit Ig2Ea; 752 ±10, 776 ± 8, 778 ± 7 for unit Ig2NWa; 791 ± 7, 795 ± 8 for unit Ig2Nb. The compositions of the most calcic plagioclase phenocrysts in the Early and Middle units are An17-19, whereas in the Late units they are An29-30. When the Fe-Ti oxide temperatures, whole rock analyses, and plagioclase compositions are incorporated into the plagioclase hygrometer, they give water contents at the onset of plagioclase crystallization of 6.6-6.9 wt% for the Early and Middle units and 4.8-4.9 wt % for the Late units. These results show internal consistency between melt inclusion analyses of water, Fe-Ti oxide thermometry, and the plagioclase-liquid hygrometer; they further support a temperature gradient across the Early, Middle, and Late Bishop Tuff units.

    Despite claims to the contrary, the compositions of magnetite and ilmenite in the Bishop Tuff correctly record the changing conditions of T and fO2 in the magma reservoir. In relatively reduced (∆NNO < 1) siliceous magmas (e.g., Bishop Tuff, Taupo units), Ti behaves compatibly (DTi ≈ 2-3.5), leading to a decrease in TiO2 activity in the melt with cooling and fractionation. In contrast, FeTi-oxides are poorer in TiO2 in more oxidized magmas (∆NNO > 1, e.g., Fish Canyon Tuff, Pinatubo), and the d(aTiO2)/dT slope can be negative. Biotite, FeTi-oxides, liquid, and possibly plagioclase largely maintained equilibrium in the Bishop Tuff magma (unlike the pyroxenes, and cores of quartz, sanidine, and zircon) prior ro and during a mixing event triggered by a deeper recharge, which, based on elemental diffusion profiles in minerals, took place at least several decades before eruption. Equilibrating phases and pumice compositions show evolving chemical variations that correlate well with mutually consistent temperatures based on the FeTi-oxides, sanidine-plagioclase, and ∆18O quartz-magnetite pairs. Early Bishop Tuff (EBT) temperatures are lower (700 to ~780‎°C) than temperatures (780 to >820°C) registered in Late Bishop Tuff (LBT), the latter defined here not strictly stratigraphically, but by the presence of orthopyroxene and reverse-zoned rims on quartz and sanidine. The claimed similarity in compositions, Zr-saturation temperatures and thermodynamically calculated temperatures (730-740°C) between EBT and less evolved LBT reflect the use of glass inclusions in quartz cores in LBT that were inherited from the low temperature rhyolitic part of the reservoir characteristic of the EBT. LBT temperatures as high as 820°C, the preservation of orthopyroxene, and the presence of reverse-zoned minerals (quartz, sanidine, zircons) are consistent with magma recharge at the base of the zoned reservoir, heating the cooler rhyolitic melt, partly remelting cumulate mush

    Fire can cause severe nitrogen (N) losses from grassland, chaparral, and temperate and boreal forest ecosystems. Paradoxically, soil ammonium levels are markedly increased by fire, resulting in high rates of primary production in re-establishing plant communities. In a manipulative experiment, we examined the influence of wild-fire ash residues on soil, microbial and plant N pools in a recently burned Californian bishop pine (Pinus muricata D. Don) forest. Ash stimulated post-fire primary production and ecosystem N retention through direct N inputs from ash to soils, as well as indirect ash effects on soil N availability to plants. These results suggest that redistribution of surface ash after fire by wind or water may cause substantial heterogeneity in soil N availability to plants, and could be an important mechanism contributing to vegetation patchiness in fire-prone ecosystems. In addition, we investigated the impact of fire on ecosystem N cycling by comparing (15)N natural abundance values from recently burned and nearby unburned P. muricata forest communities. At the burned site, (15)N natural abundance in recolonising species was similar to that in bulk soil organic matter. By contrast, there was a marked (15)N depletion in the same species relative to the total soil N pool at the unburned site. These results suggest that plant uptake of nitrate (which tends to be strongly depleted in (15)N because of fractionation during nitrification) is low in recently burned forest communities but could be an important component of eco- system N cycling in mature conifer stands.

  17. Soil contamination with silver nanoparticles reduces Bishop pine growth and ectomycorrhizal diversity on pine roots

    Soil contamination by silver nanoparticles (AgNP) is of potential environmental concern but little work has been carried out on the effect of such contamination on ectomycorrhizal fungi (EMF). EMF are essential to forest ecosystem functions as they are known to enhance growth of trees by nutrient transfer. In this study, soil was experimentally contaminated with AgNP (0, 350 and 790 mg Ag/kg) and planted with Bishop pine seedlings. The effect of AgNP was subsequently measured, assessing variation in pine growth and ectomycorrhizal diversity associated with the root system. After only 1 month, the highest AgNP level had significantly reduced the root length of pine seedlings, which in turn had a small effect on above ground plant biomass. However, after 4 months growth, both AgNP levels utilised had significantly reduced both pine root and shoot biomass. For example, even the lower levels of AgNP (350 mg Ag/kg) soil, reduced fresh root biomass by approximately 57 %. The root systems of the plants grown in AgNP-contaminated soils lacked the lateral and fine root development seen in the control plants (no AgNP). Although, only five different genera of EMF were found on roots of the control plants, only one genus Laccaria was found on roots of plants grown in soil containing 350 mg AgNP/kg. At the higher levels of AgNP contamination, no EMF were observed. Furthermore, extractable silver was found in soils containing AgNP, indicating potential dissolution of silver ions (Ag+) from the solid AgNP.

    The ~0.76 Ma Bishop Tuff eruption in eastern California is an archetypal example of the products of a compositionally stratified magma chamber. Key issues regarding the melt-dominant magma body that have arisen from recent studies include the role of horizontal variability versus vertical stratification, and the nature and timing of a late-stage ingress of compositionally contrasting melt. The latter is reflected in, for example, CL-bright rims on quartz, and Sr- and Ba-rich rims on sanidines, both of which are reported in samples from ignimbrite erupted from vents along the northern caldera rim. Various studies have placed contrasting temporal constraints on assembly and evacuation of the Bishop Tuff magma body and the processes occurring within it from one or two mineral phases. Although the overall crystal specific record is more complex, it has the potential to distinguish between mixing, in-situ crystallisation and other magmatic processes, and resolve the associated timings of these events. Zircon has been widely utilised in the Bishop Tuff and other silicic systems because of its unique records of information about the ages and P-T-X environments of growth. Here we present SHRIMP-RG ion probe data from Bishop Tuff zircons, collected from samples spanning the full eruptive sequence. A combination of age data, textural analysis and trace element analysis is used to yield insights into magma chamber development and the pre-eruptive state of the melt-dominant magma body, as evidenced in material erupted from different vent areas around what became the Long Valley caldera. U-Pb dating of 307 spots from all zones in crystals from all samples yields a strongly unimodal age spectrum, with a mean age of 794+/-3 ka (10 spots rejected, MSWD = 2.0). CL images of the dated zircon suites show the appearance of bright-rimmed zircons in later-erupted ignimbrite packages (accompanied generally by bright-rimmed sanidine and quartz crystals), but with diversity in the

    Tabled execution is a generalization of memorization developed by the logic programming community. It not only saves results from tabled predicates, but also stores the set of currently active calls to them; tabled execution can thus provide meaningful semantics for programs that seemingly contain infinite recursions with the same arguments. In logic programming, tabled execution is used for many purposes, both for improving the efficiency of programs, and making tasks simpler and more direct to express than with normal logic programs. However, tabled execution is only infrequently applied in mainstream functional languages such as Scheme. We demonstrate an elegant implementation of tabled execution in Scheme, using a mix of continuation-passing style and mutable data. We also show the use of tabled execution in Scheme for a problem in formal language and automata theory, demonstrating that tabled execution can be a valuable tool for Scheme users.

    A major innovation of the Civil Service Reform Act of 1978 was the creation of a Senior Executive Service (SES). The purpose of the SES is both simple and bold: to attract executives of the highest quality into Federal service and to retain them by providing outstanding opportunities for career growth and reward. The SES is intended to: provide greater authority in managing executive resources; attract and retain highly competent executives, and assign them where they will effectively accomplish their missions and best use their talents; provide for systematic development of executives; hold executives accountable for individual and organizational performance; reward outstanding performers and remove poor performers; and provide for an executive merit system free of inappropriate personnel practices and arbitrary actions. This Handbook summarizes the key features of the SES at NASA. It is intended as a special welcome to new appointees and also as a general reference document. It contains an overview of SES management at NASA, including the Executive Resources Board and the Performance Review Board, which are mandated by law to carry out key SES functions. In addition, assistance is provided by a Senior Executive Committee in certain reviews and decisions and by Executive Position Managers in day-to-day administration and oversight.

  3. Detection of parametric changes in the Peyrard-Bishop- Dauxois model of DNA using nonlinear Kalman filtering.

    2015-01-01

    The derivative-free nonlinear Kalman filter is proposed for state estimation and fault diagnosis in distributed parameter systems of the wave-type and particularly in the Peyrard-Bishop-Dauxois model of DNA dynamics. At a first stage, a nonlinear filtering approach is introduced for estimating the dynamics of the Peyrard-Bishop-Dauxois 1D nonlinear wave equation, through the processing of a small number of measurements. It is shown that the numerical solution of the associated partial differential equation results in a set of nonlinear ordinary differential equations. With the application of a diffeomorphism that is based on differential flatness theory it is shown that an equivalent description of the system is obtained in the linear canonical (Brunovsky) form. This transformation enables to obtain local estimates about the state vector of the DNA model through the application us of the standard Kalman filter recursion. At a second stage, the local statistical approach to fault diagnosis is used to perform fault diagnosis for this distributed parameter system by processing with statistical tools the differences (residuals) between the output of the Kalman filter and the measurements obtained from the distributed parameter system. Optimal selection of the fault threshold is succeeded by using the local statistical approach to fault diagnosis. The efficiency of the proposed filtering approach in the problem of fault diagnosis for parametric change detection, in nonlinear wave-type models of DNA dynamics, is confirmed through simulation experiments.

  4. Melt-inclusion-hosted excess 40Ar in quartz crystals of the Bishop and Bandelier magma systems

    2001-01-01

    40Ar/39Ar experiments on melt-inclusion-bearing quartz (MIBQ) from the Bishop and Bandelier Tuff Plinian deposits indicate high concentrations of excess 40Ar in melt inclusions. Two rhyolite glass melt inclusion populations are present in quartz; exposed melt inclusions and trapped melt inclusions. Air-abrasion mill grinding and hydrofluoric acid treatments progressively remove exposed melt inclusions while leaving trapped melt inclusions unaffected. Laser step-heating of MIBQ yields increasing apparent ages as a function of exposed melt inclusion removal, reflecting the higher nonatmospheric 40Ar concentrations hosted in trapped melt inclusions. Exposed melt inclusion-free MIBQ from the Bishop, Upper Bandelier, and Lower Bandelier Tufts yield total-gas ages of 3.70 ?? 1.00 Ma, 11.54 ?? 0.87 Ma, and 14.60 ?? 1.50 Ma, respectively. We interpret these old apparent ages as compelling evidence for the presence of excess 40Ar in MIBQ. Trapped melt inclusions in sanidine phenocrysts may contain excess 40Ar concentrations similar to those in MIBQ. This excess 40Ar has the potential to increase single-crystal laser-fusion ages of sanidine by tens of thousands of years, relative to the actual eruption age.

    2015-04-01

    The Bishop tuff is a rhyolitic ignimbrite deposited by a supereruption 0.76 million years ago that formed the Long Valley Caldera in California, USA. Pamukcu et. al (2012) identifies two distinct crystal populations present in the Bishop Tuff, the first being a long-lived, large phenocryst population that records storage conditions, and the second a rapidly nucleated, quickly staunched microlite population thought to result from eruptive decompression. Laboratory experiments to reproduce this quickly grown population may help constrain the conditions and rates under which decompression took place. Rapid nucleation of microlites is accompanied by just as rapid bubble nucleation when volatiles exsolve during decompression; the size distribution of vesicles in eruptive products may thus provide important information on syn-eruptive processes. In this study we combine information from vesicle size distributions on natural pumice with data on experimentally produced microlite crystals with the goal of better understanding the syn-eruptive evolution of a supereruption-forming magma body. Decompression experiments are run using a natural Bishop tuff pumice clast ground and melted in the presence of water to obtain a melt representative of late-erupted Bishop Tuff (LBT) magmas. Experimental charges were subjected to decompression at varying rates and initial temperatures. At this time five experiments have been completed. All decompression experiments start at 130MPa, consistent with water concentration in LBT glass inclusions, and end at 10 MPa. Initial temperatures are either 710°C or 785°C, while decompression rates are 20 MPa/hr, 5.5MPa/hr, or 1.7MPa/hr Experimental products were compared to natural products using Scanning Electron Microscopy to document eventual crystal rims and microlites. We have been successful in causing limited feldspar crystallization, but have yet to generate quartz microlites. Bubble size distributions are obtained by analyzing x

    The last few years have seen a resurgence of interest in the use of symbolic execution -- a program analysis technique developed more than three decades ago to analyze program execution paths. Scaling symbolic execution and other path-sensitive analysis techniques to large systems remains challenging despite recent algorithmic and technological advances. An alternative to solving the problem of scalability is to reduce the scope of the analysis. One approach that is widely studied in the context of regression analysis is to analyze the differences between two related program versions. While such an approach is intuitive in theory, finding efficient and precise ways to identify program differences, and characterize their effects on how the program executes has proved challenging in practice. In this paper, we present Directed Incremental Symbolic Execution (DiSE), a novel technique for detecting and characterizing the effects of program changes. The novelty of DiSE is to combine the efficiencies of static analysis techniques to compute program difference information with the precision of symbolic execution to explore program execution paths and generate path conditions affected by the differences. DiSE is a complementary technique to other reduction or bounding techniques developed to improve symbolic execution. Furthermore, DiSE does not require analysis results to be carried forward as the software evolves -- only the source code for two related program versions is required. A case-study of our implementation of DiSE illustrates its effectiveness at detecting and characterizing the effects of program changes.

    Generating plans for execution imposes a different set of requirements on the planning process than those imposed by planning alone. In highly unpredictable execution environments, a fully-grounded plan may become inconsistent frequently when the world fails to behave as expected. Intelligent execution permits making decisions when the most up-to-date information is available, ensuring fewer failures. Planning should acknowledge the capabilities of the execution system, both to ensure robust execution in the face of uncertainty, which also relieves the planner of the burden of making premature commitments. We present Plan Identification Functions (PIFs), which formalize what it means for a plan to be executable, md are used in conjunction with a complete model of system behavior to halt the planning process when an executable plan is found. We describe the implementation of plan identification functions for a temporal, constraint-based planner. This particular implementation allows the description of many different plan identification functions. characteristics crf the xectieonfvii rnm-enft,h e best plan to hand to the execution system will contain more or less commitment and information.

  11. Does nest luminosity play a role in recognition of parasitic eggs in domed nests? A case study of the red bishop.

    2014-12-01

    Certain light environments may hinder egg discrimination by hosts of foreign eggs, which could in some circumstances lead to the acceptance of non-mimetic eggs by hosts. We measured light parameters at red bishop (Euplectes orix) nests and used a model of avian visual processing to quantify the detectability of eggs in the light environment in which they are perceived. We found that the overall amount of light was very variable between red bishop nests and always sufficient for colour discrimination. A model of avian visual processing revealed that nest luminosity had no influence on host responses towards eggs which were painted dark brown. Dark eggs do not appear to be cryptic in red bishop nests and can be distinguished with ease, whereas natural red bishop eggs are usually accepted, despite the domed structure of the nest. We found little variation in both chromatic and achromatic contrasts between host and artificial eggs, indicating that there was very little variation in the light quality inside nests. We suggest that nest luminosity is likely to play a role in egg recognition in situations when light reaches threshold values for colour discrimination, i.e. in scotopic as opposed to photopic vision. Rejection rates for dark eggs were higher than for bright (conspecific) foreign eggs. More investigation of domed nest-building species is required, as this type of nest appears to have a highly variable light environment, dependent on both nest structure and habitat.

    2012-01-01

    This paper introduces memoized symbolic execution (Memoise), a novel approach for more efficient application of forward symbolic execution, which is a well-studied technique for systematic exploration of program behaviors based on bounded execution paths. Our key insight is that application of symbolic execution often requires several successive runs of the technique on largely similar underlying problems, e.g., running it once to check a program to find a bug, fixing the bug, and running it again to check the modified program. Memoise introduces a trie-based data structure that stores the key elements of a run of symbolic execution. Maintenance of the trie during successive runs allows re-use of previously computed results of symbolic execution without the need for re-computing them as is traditionally done. Experiments using our prototype embodiment of Memoise show the benefits it holds in various standard scenarios of using symbolic execution, e.g., with iterative deepening of exploration depth, to perform regression analysis, or to enhance coverage.

    In grapheme-color synesthesia, a number or letter can evoke two different and possibly conflicting (real and synesthetic) color sensations at the same time. In this study, we investigate the relationship between synesthesia and executive control functions. First, no general skill differences were obtained between synesthetes and non-synesthetes in classic executive control paradigms. Furthermore, classic executive control effects did not interact with synesthetic behavioral effects. Third, we found support for our hypothesis that inhibition of a synesthetic color takes effort and time. Finally, individual differences analyses showed no relationship between the two skills; performance on a 'normal' Stroop task does not predict performance on a synesthetic Stroop task. Across four studies, the current results consistently show no clear relationship between executive control functions and synesthetic behavioral effects. This raises the question of which mechanisms are at play in synesthetic 'management' during the presence of two conflicting (real and synesthetic) sensations.

An average age of 758.9 ?? 1.8 ka, standard error of the mean (SEM), was obtained for individual sanidine crystals or groups of several crystals, determined from ???70 individual analyses of sanidine separates from 11 sample groups obtained at five localities. The basal air fall pumice (757.7 ?? 1.8 ka) and overlying ash flow tuff (762.2 ?? 4.7 ka) from near the source yield essentially the same dates within errors of analysis, suggesting that the two units were emplaced close in time. A date on distal Bishop air fall ash bed at Friant, California, ???100 km to the west of the source area, is younger, 750.1 ?? 4.3 ka, but not significantly different within analytical error (??1 standard deviation). Previous dates of the Bishop Tuff, obtained by others using conventional K-Ar and the fission track method on zircons, ranged from ???650 ka to ???1.0 Ma. The most recent, generally accepted date by the K-Ar method on sanidine was 738 ?? 3 ka. We infer, as others before, that many K-Ar dates on sanidine feldspar are too young owing to incomplete degassing of radiogenic Ar during fusion in the K-Ar technique and that many older K-Ar dates are too old owing to detrital or xenocrystic contamination in the larger samples that are necessary for the technique. The new dates are similar to recent 40Ar/39Ar ages of the Bishop Tuff determined on individual samples by others but are derived from a larger proximal sample population and from multiple analysis of each sample. The results provide a definitive and precise age calibration of this widespread chronostratigraphic marker in the western United States and northeastern Pacific Ocean. We calculated the

  18. Educating executive function.

    PubMed

    Blair, Clancy

    2017-01-01

    Executive functions are thinking skills that assist with reasoning, planning, problem solving, and managing one's life. The brain areas that underlie these skills are interconnected with and influenced by activity in many different brain areas, some of which are associated with emotion and stress. One consequence of the stress-specific connections is that executive functions, which help us to organize our thinking, tend to be disrupted when stimulation is too high and we are stressed out, or too low when we are bored and lethargic. Given their central role in reasoning and also in managing stress and emotion, scientists have conducted studies, primarily with adults, to determine whether executive functions can be improved by training. By and large, results have shown that they can be, in part through computer-based videogame-like activities. Evidence of wider, more general benefits from such computer-based training, however, is mixed. Accordingly, scientists have reasoned that training will have wider benefits if it is implemented early, with very young children as the neural circuitry of executive functions is developing, and that it will be most effective if embedded in children's everyday activities. Evidence produced by this research, however, is also mixed. In sum, much remains to be learned about executive function training. Without question, however, continued research on this important topic will yield valuable information about cognitive development.

    Tasks may be planned for execution on a single processor or are split up by the designer for execution among a plurality of signal processors. The tasks are modeled using a design aid called a precedence graph, from which a dependency table and a prerequisite table are established for reference within each processor. During execution, at the completion of a given task, an end of task interrupt is provided from any processor which has completed a task to any and all other processors including itself in which completion of that task is a prerequisite for commencement of any dependent tasks. The relevant updated data may be transferred by the processor either before or after signalling task completion to the processors needing the updated data prior to commencing execution of the dependent tasks. Coherency may be ensured, however, by sending the data before the interrupt. When the end of task interrupt is received in a processor, its dependency table is consulted to determine those tasks dependent upon completion of the task which has just been signalled as completed, and task dependency signals indicative thereof are provided and stored in a current status list of a prerequisite table. The current status of all current prerequisites are compared to the complete prerequisites listed for all affected tasks and those tasks for which the comparison indicates that all prerequisites have been met are queued for execution in a selected order.

    1984-01-01

    The Bishop Tuff represents a single eruption of chemically zoned rhyolitic magma. Six whole rock samples spanning the compositional and temperature range yield initial 87Sr 86Sr of 0.7060-0.7092 and ??18O of 5.9-10.3???. Six constituent sanidines yield smaller ranges of initial 87Sr 86Sr of 0.7061-0.7069 and ??18O of 6.7-7.9. In contrast 143Nd 144Nd ratios for the six whole rocks and two constituent magnetites exhibit negligible variation with a mean of 0.51258 ?? 1. These data are used to show that the phenocrysts were precipitated from an already chemically zoned liquid, that the zoning process involved negligible assimilation of, or exchange with, country rocks and that the extreme Sr and O isotopic disequilibria are probably the result of post-eruptive interaction with meteoric water. The parent magma had ??Nd = -0.9, ??Sr = +23 and ??18O = 7??? and was formed from mantle-derived magmas and/or melts of lower crustal rocks isotopically similar to parts of the Sierra Nevada Batholith. ?? 1984.

  8. Executive Functioning in Schizophrenia

    PubMed Central

    Orellana, Gricel; Slachevsky, Andrea

    2013-01-01

    The executive function (EF) is a set of abilities, which allows us to invoke voluntary control of our behavioral responses. These functions enable human beings to develop and carry out plans, make up analogies, obey social rules, solve problems, adapt to unexpected circumstances, do many tasks simultaneously, and locate episodes in time and place. EF includes divided attention and sustained attention, working memory (WM), set-shifting, flexibility, planning, and the regulation of goal directed behavior and can be defined as a brain function underlying the human faculty to act or think not only in reaction to external events but also in relation with internal goals and states. EF is mostly associated with dorsolateral prefrontal cortex (PFC). Besides EF, PFC is involved in self-regulation of behavior, i.e., the ability to regulate behavior according to internal goals and constraints, particularly in less structured situations. Self-regulation of behavior is subtended by ventral medial/orbital PFC. Impairment of EF is one of the most commonly observed deficits in schizophrenia through the various disease stages. Impairment in tasks measuring conceptualization, planning, cognitive flexibility, verbal fluency, ability to solve complex problems, and WM occur in schizophrenia. Disorders detected by executive tests are consistent with evidence from functional neuroimaging, which have shown PFC dysfunction in patients while performing these kinds of tasks. Schizophrenics also exhibit deficit in odor identifying, decision-making, and self-regulation of behavior suggesting dysfunction of the orbital PFC. However, impairment in executive tests is explained by dysfunction of prefronto-striato-thalamic, prefronto-parietal, and prefronto-temporal neural networks mainly. Disorders in EFs may be considered central facts with respect to schizophrenia and it has been suggested that negative symptoms may be explained by that executive dysfunction. PMID:23805107

  9. What executives should remember.

    PubMed

    Drucker, Peter F

    2006-02-01

    In more than 30 essays for Harvard Business Review, Peter Drucker (1909-2005) urged readers to take on the hard work of thinking--always combined, he insisted, with decisive action. He closely analyzed the phenomenon of knowledge work--the growing call for employees who use their minds rather than their hands--and explained how it challenged the conventional wisdom about the way organizations should be run. He was intrigued by employees who knew more about certain subjects than their bosses or colleagues but who still had to cooperate with others in a large organization. As the business world matured in the second half of the twentieth century, executives came to think that they knew how to run companies--and Drucker took it upon himself to poke holes in their assumptions, lest organizations become stale. But he did so sympathetically, operating from the premise that his readers were intelligent, hardworking people of goodwill. Well suited to HBR's format of practical, idea-based essays for executives, his clear-eyed, humanistic writing enriched the magazine time and again. This article is a compilation of the savviest management advice Drucker offered HBR readers over the years--in short, his greatest hits. It revisits the following insightful, influential contributions: "The Theory of the Business" (September-October 1994), "Managing for Business Effectiveness" (May-June 1963), "What Business Can Learn from Nonprofits" (July-August 1989), "The New Society of Organizations" (September-October 1992), "The Information Executives Truly Need" (January-February 1995), "Managing Oneself" (March-April 1999 republished January 2005), "They're Not Employees, They're People" (February 2002), "What Makes an Effective Executive" (June 2004).

    This study aimed to specify the neural mechanisms underlying the link between low household income and diminished executive control in the preschool period. Specifically, we examined whether individual differences in the neural processes associated with executive attention and inhibitory control accounted for income differences observed in performance on a neuropsychological battery of executive control tasks. The study utilized a sample of preschool-aged children (N = 118) whose families represented the full range of income, with 32% of families at/near poverty, 32% lower income, and 36% middle to upper income. Children completed a neuropsychological battery of executive control tasks and then completed two computerized executive control tasks while EEG data were collected. We predicted that differences in the event-related potential (ERP) correlates of executive attention and inhibitory control would account for income differences observed on the executive control battery. Income and ERP measures were related to performance on the executive control battery. However, income was unrelated to ERP measures. The findings suggest that income differences observed in executive control during the preschool period might relate to processes other than executive attention and inhibitory control.

  12. Zircon-scale insights into the history of a Supervolcano, Bishop Tuff, Long Valley, California, with implications for the Ti-in-zircon geothermometer

    2011-01-01

    Zircon has the outstanding capacity to record chronological, thermal, and chemical information, including the storage history of zoned silicic magma reservoirs like the one responsible for the Bishop Tuff of eastern California, USA. Our novel ion microprobe approach reveals that Bishop zircon rims with diverse chemical characteristics surround intermediate domains with broadly similar compositions. The highest Y, REE, U, and Th concentrations tend to accompany the largest excesses in Y + REE3+:P beyond what can be explained by xenotime substitution in zircon. Apparent Ti-in-zircon temperatures of <720??C for zircon rims are distinctly lower than most of the range in eruption temperatures, as estimated from FeTi-oxide equilibria and zircon solubility at quench. While permissive of crystallization of zircon at near-solidus conditions, the low Ti-in-zircon temperatures are probably better explained by sources of inaccuracy in the temperature estimates. After apparently nucleating from different melts, zircons from across the Bishop Tuff compositional spectrum may have evolved to broadly similar chemical and thermal conditions and therefore it is possible that there was no significant thermal gradient in the magma reservoir at some stage in its evolution. There is also no compelling evidence for punctuated heat ?? chemical influxes during the intermediate stages of zircon growth. Judging by the zircon record, the main volume of the erupted magma evolved normally by secular cooling but the latest erupted portion is characterized by a reversal in chemistry that appears to indicate perfusion of the magma reservoir by-or zircon entrainment in-a less evolved melt from the one in which the zircons had previously resided. ?? 2010 Springer-Verlag.

  13. Discovering of execution patterns of subprograms in execution traces

    NASA Astrophysics Data System (ADS)

    Komorowski, Michał

    2015-09-01

    This article describes an approach to the analysis of historical debuggers logs (execution traces). Historical debuggers are tools that provide insight into the history of programs execution. The author focuses on finding execution patterns of subprograms in these logs in an efficient way and proposes a method of visualising them. Execution patterns are a form of automatically generated specification/documentation of software which show usage of subprograms. In order to discover them in execution traces an existing algorithm was adapted. This algorithm is based on suffix arrays and it finds patterns in text application logs in the linear time with the respect to the length of logs. Additionally, Extended Call Graphs were introduced to visualise the execution patterns. They contain more information in comparison with standard call graphs.

    Full polarization data gathered by the NASA/JPL AIRSAR P-band radar in Gilmore Creek, Alaska (1993), Half Moon Bay, California (1994), and Bishop, California (1995) are imaged using full polarization displays. Full polarization symbol displays of reflector signatures and of simulated small aircraft crash sites are presented. In addition, ideal polarimetric reflector responses are compared to measured reflector signatures extracted from ADTS MMW SAR scenes and AIRSAR scenes. It is demonstrated that full polarization displays can be used to quickly identify polarization calibration errors based on clutter responses alone.

  15. On Nondeterministic Workflow Executions

    NASA Astrophysics Data System (ADS)

    Potapova, Alexandra; Su, Jianwen

    The ability to compose existing services to form new functionality is one of the most promising ideas enabled by SOA and the framework of (web) services. A composition or a workflow often involves services distributed over a network and possibly many organizations and administrative domains. Nondeterminism could occur in a composition in at least two ways. The first form is the result of modeling abstraction that hides the detail information and thus makes the "computation" appear non-deterministic. The second form is closely related to "operational optimization", e.g., one may try to invoke more than multiple services for a task, whichever completes first will produce the result and preempts all other services. In this paper, we focus on the latter and measure the complexity of service execution as the amount of needed resources and controlling mechanism for executing nondeterministic service compositions. We formalize the model and complexity problem and develop technical results for this problem in the general setting as well as special cases.

  16. Single-crystal 40Ar/39Ar incremental heating reveals bimodal sanidine ages in the Bishop Tuff

    NASA Astrophysics Data System (ADS)

    Andersen, N. L.; Jicha, B. R.; Singer, B. S.

    2015-12-01

    The 650 km3 Bishop Tuff (BT) is among the most studied volcanic deposits because it is an extensive marker bed deposited just after the Matuyama-Brunhes boundary. Reconstructions of the vast BT magma reservoir from which high-silica rhyolite erupted have long influenced thinking about how large silicic magma systems are assembled, crystallized, and mixed. Yet, the longevity of the high silica rhyolitic melt and exact timing of the eruption remain controversial due to recent conflicting 40Ar/39Ar sanidine vs. SIMS and ID-TIMS U-Pb zircon dates. We have undertaken 21 40Ar/39Ar incremental heating ages on 2 mm BT sanidine crystals from pumice in 3 widely separated outcrops of early-erupted fall and flow units. Plateau ages yield a bimodal distribution: a younger group has a mean of 766 ka and an older group gives a range between 772 and 782 ka. The younger population is concordant with the youngest ID-TIMS and SIMS U-Pb zircon ages recently published, as well as the astronomical age of BT in marine sediment. Of 21 crystals, 17 yield older, non-plateau, steps likely affected by excess Ar that would bias traditional 40Ar/39Ar total crystal fusion ages. The small spread in older sanidine ages, together with 25+ kyr of pre-eruptive zircon growth, suggest that the older sanidines are not partially outgassed xenocrysts. A bimodal 40Ar/39Ar age distribution implies that some fraction of rhyolitic melt cooled below the Ar closure temperature at least 10 ky prior to eruption. We propose that rapid "thawing" of a crystalline mush layer released older crystals into rhyolitic melt from which sanidine also nucleated and grew immediately prior to the eruption. High precision 40Ar/39Ar dating can thus provide essential information on thermo-physical processes at the millenial time scale that are critical to interpreting U-Pb zircon age distributions that are complicated by large uncertainties associated with zircon-melt U-Th systematics.

    Plan execution is a cornerstone of spacecraft operations, irrespective of whether the plans to be executed are generated on board the spacecraft or on the ground. Plan execution frameworks vary greatly, due to both different capabilities of the execution systems, and relations to associated decision-making frameworks. The latter dependency has made the reuse of execution and planning frameworks more difficult, and has all but precluded information sharing between different execution and decision-making systems. As a step in the direction of addressing some of these issues, a general plan execution language, called the Plan Execution Interchange Language (PLEXIL), is being developed. PLEXIL is capable of expressing concepts used by many high-level automated planners and hence provides an interface to multiple planners. PLEXIL includes a domain description that specifies command types, expansions, constraints, etc., as well as feedback to the higher-level decision-making capabilities. This document describes the grammar and semantics of PLEXIL. It includes a graphical depiction of this grammar and illustrative rover scenarios. It also outlines ongoing work on implementing a universal execution system, based on PLEXIL, using state-of-the-art rover functional interfaces and planners as test cases.

    2015-01-01

    Children spend a lot of time watching television on its many platforms: directly, online, and via videos and DVDs. Many researchers are concerned that some types of television content appear to negatively influence children's executive function. Because (1) executive function predicts key developmental outcomes, (2) executive function appears to be influenced by some television content, and (3) American children watch large quantities of television (including the content of concern), the issues discussed here comprise a crucial public health issue. Further research is needed to reveal exactly what television content is implicated, what underlies television's effect on executive function, how long the effect lasts, and who is affected.

    For six years, Cynthia Cunningham and Shelley Murray shared an executive job at Fleet Bank. One desk, one chair, one computer, one telephone, and one voice-mail account. To their clients and colleagues, they were effectively one person, though one person with the strengths and ideas of two, seamlessly handing projects back and forth. Although their department was dissolved after the bank merged with Bank of America, the two continue to consider themselves a package-they have one resume, and they are seeking their next opportunity together. Their choice to share a job was not only a quality-of-life decision but one intended to keep their careers on course: "Taking two separate part-time jobs would have thrown us completely off track" they write in this first-person account."We're both ambitious people, and neither of us wanted just a job. We wanted careers" In this article, the two highly motivated women reveal their determination to manage the demands of both family and career. Flextime,telecommuting, and compressed workweeks are just some of the options open to executives seeking greater work/ life balance, and the job share, as described by Cunningham and Murray, could well be the next solution for those wishing to avoid major trade-offs between their personal and professional lives. Cunningham and Murray describe in vivid detail how they structured their unusual arrangement, how they sold themselves to management, and the hurdles they faced along the way. Theirs is a win-win story, for the company and for them.

    This thesis is an attempt to develop an ethic for those who must perform soldierly duties in this era. It is an examination of core values, and how these values have been translated into military ethics and obligations within the context of western civilization. This study uses the most recent application of just-war theory, the Catholic Bishop's Pastoral on nuclear war, The Challenge of Peace: God's Promise and Our Response, and compares its instruction to selected findings of another contemporary application, the Nuremberg War Trials. The manner in which we construct and reinforce our moral values in conscience, coupled with appreciation for the sanctity of human existence, evolve as fundamental underlying principles. After having established the scope of authority from which the Catholic Bishop's Pastoral derives its credibility, these principles are compared against the United States Army Ethic and a contemporary ethic is proposed. The study concludes that ultimately we are responsible for the decisions and choices that we make. Soldiers are not absolved, especially within the Judeo-Christian context, from the obligation to make choices based upon sound moral reasoning, simply because they are engaged in activities that run counter to orderly human existence.

    Fischer, Topher; Mercer, Eric; Rungta, Neha

    2011-01-01

    Improper use of Inter-Process Communication (IPC) within concurrent systems often creates data races which can lead to bugs that are challenging to discover. Techniques that use Satisfiability Modulo Theories (SMT) problems to symbolically model possible executions of concurrent software have recently been proposed for use in the formal verification of software. In this work we describe a new technique for modeling executions of concurrent software that use a message passing API called MCAPI. Our technique uses an execution trace to create an SMT problem that symbolically models all possible concurrent executions and follows the same sequence of conditional branch outcomes as the provided execution trace. We check if there exists a satisfying assignment to the SMT problem with respect to specific safety properties. If such an assignment exists, it provides the conditions that lead to the violation of the property. We show how our method models behaviors of MCAPI applications that are ignored in previously published techniques.

We propose a flexible execution engine that can be used in clinical decision support applications, and also for medical education, or for integrating guidelines into the clinical workflow. We also focus our attention on temporal issues in the execution of guidelines, including the treatment of composite, concurrent and/or cyclic actions. PMID:11080004

  12. [The attempts of Bishop Ivan Sintić (1792-1837) to treat snake and other animal bites: from intuition to scientific dispute].

    PubMed

    Velcic, Franjo

    2012-01-01

    This manuscript describes an attempt to treat snake and other animal bites using an ointment made of a plant Aster atticus (sternkraut, of the family Aster). The recipe for this ointment had passed from an Istrian Bernardo Alessandri to bishop Ivan Anton Sintić at the end of the 18th century. At the request by the Austrian administration of the Province of Zadar, Sintić published a booklet on how to prepare the plant and use it, and the administration distributed the booklet to local practitioners. Encouraged by the new therapy, physician Srećko Randić of Bakar, took it for the subject of his doctoral dissertation, an published it in Vienna in 1840. However, the efficiency of this therapy was disputed by the new island of Krk physician Ivan Krstitelj Kubić after years of follow up and investigation.

  15. Multiprocessor execution of functional programs

    Goldberg, B. )

    1988-10-01

    Functional languages have recently gained attention as vehicles for programming in a concise and element manner. In addition, it has been suggested that functional programming provides a natural methodology for programming multiprocessor computers. This paper describes research that was performed to demonstrate that multiprocessor execution of functional programs on current multiprocessors is feasible, and results in a significant reduction in their execution times. Two implementations of the functional language ALFL were built on commercially available multiprocessors. Alfalfa is an implementation on the Intel iPSC hypercube multiprocessor, and Buckwheat is an implementation on the Encore Multimax shared-memory multiprocessor. Each implementation includes a compiler that performs automatic decomposition of ALFL programs and a run-time system that supports their execution. The compiler is responsible for detecting the inherent parallelism in a program, and decomposing the program into a collection of tasks, called serial combinators, that can be executed in parallel. The abstract machine model supported by Alfalfa and Buckwheat is called heterogeneous graph reduction, which is a hybrid of graph reduction and conventional stack-oriented execution. This model supports parallelism, lazy evaluation, and higher order functions while at the same time making efficient use of the processors in the system. The Alfalfa and Buckwheat runtime systems support dynamic load balancing, interprocessor communication (if required), and storage management. A large number of experiments were performed on Alfalfa and Buckwheat for a variety of programs. The results of these experiments, as well as the conclusions drawn from them, are presented.

    Introduction L'objectif était d'évaluer la mesure échographique de l’ouverture de l’orifice interne du col dans la prédiction de l’issue de la maturation cervicale et la comparer au Score de Bishop. Méthodes Nous avons mené une étude prospective sur 10 mois, entre Juillet 2012 et avril 2013 colligeant 77 femmes nullipares admises pour déclenchement du travail à un terme de 41 SA avec un Score de Bishop < 6. La mesure de l’ouverture de l’orifice interne du col a été réalisée par échographie transvaginale et le score de Bishop a été déterminé par l'examen clinique. Toutes les patientes ont eu une maturation cervicale par des prostaglandines. Résultats La maturation cervicale était réussie chez 63 patients (81%). Le Score de Bishop et l’ouverture de l’orifice interne du col se sont révélés statistiquement associés au succès ou l’échec de la maturation cervicale. Le taux de succès de la maturation était de 100% lorsque l’ouverture de l’orifice interne du col était égale ou supérieure à 5 mm (sensibilité: 54%; spécificité: 86%). Les courbes ROC ont montré que la mesure de l’orifice interne du col était plus prédictive de l’issue de la maturation cervicale que le Score de Bishop (Aire sous la courbe respectivement 0.733 et 0.704). Conclusion Comparée au score de Bishop, la mesure échographique de l’ouverture de l’orifice interne du col est plus prédictive du succès de la maturation cervicale chez les femmes nullipares à 41 semaines d’aménorrhée avec un col défavorable.

    2012-01-01

    We describe a testing technique that uses information computed by symbolic execution of a program unit to guide the generation of inputs to the system containing the unit, in such a way that the unit's, and hence the system's, coverage is increased. The symbolic execution computes unit constraints at run-time, along program paths obtained by system simulations. We use machine learning techniques treatment learning and function fitting to approximate the system input constraints that will lead to the satisfaction of the unit constraints. Execution of system input predictions either uncovers new code regions in the unit under analysis or provides information that can be used to improve the approximation. We have implemented the technique and we have demonstrated its effectiveness on several examples, including one from the aerospace domain.

    To achieve the goal of building an autonomous agent, the usually disjoint capabilities of planning, execution, and learning must be used together. An architecture, called MAX, within which cognitive capabilities can be purposefully and intelligently integrated is described. The architecture supports the codification of capabilities as explicit knowledge that can be reasoned about. In addition, specific problem solving, learning, and integration knowledge is developed.

    The authors review the role of financial accounting information from the perspective of a radiology executive. They begin by introducing the role of pro forma statements. They discuss the fundamental concepts of accounting, including the matching principle and accrual accounting. The authors then explore the use of financial accounting information in making investment decisions in diagnostic medical imaging. The paper focuses on critically evaluating the benefits and limitations of financial accounting for decision making in a radiology practice.

  12. What makes an effective executive.

    PubMed

    Drucker, Peter F

    2004-06-01

    An effective executive does not need to be a leader in the typical sense of the word. Peter Drucker, the author of more than two dozen HBR articles, says some of the best business and nonprofit CEOs he has worked with over his 65-year consulting career were not stereotypical leaders. They ranged from extroverted to nearly reclusive, from easygoing to controlling, from generous to parsimonious. What made them all effective is that they followed the same eight practices: They asked, "What needs to be done?" They also asked, "What is right for the enterprise?" They developed action plans. They took responsibility for decisions. They took responsibility for communicating. They were focused on opportunities rather than problems. They ran productive meetings. And they thought and said "we" rather than "I." The first two practices provided them with the knowledge they needed. The next four helped them convert this knowledge into effective action, for knowledge is useless to executives until it has been translated into deeds. The last two ensured that the whole organization felt responsible and accountable. Effective executives know that they have authority only because they have the trust of the organization. This means they must think of the needs and opportunities of the organization before they think of their own needs and opportunities. The author also suggests a ninth practice that's so important, he elevates it to the level of a rule: Listen first, speak last. The demand for effective executives is much too great to be satisfied by those few people who are simply born to lead. Effectiveness is a discipline. And, like every discipline, it can be learned and must be earned.

    1988-01-01

    The design and implementation of a Concurrent Image Processing Executive (CIPE), which is intended to become the support system software for a prototype high performance science analysis workstation are discussed. The target machine for this software is a JPL/Caltech Mark IIIfp Hypercube hosted by either a MASSCOMP 5600 or a Sun-3, Sun-4 workstation; however, the design will accommodate other concurrent machines of similar architecture, i.e., local memory, multiple-instruction-multiple-data (MIMD) machines. The CIPE system provides both a multimode user interface and an applications programmer interface, and has been designed around four loosely coupled modules; (1) user interface, (2) host-resident executive, (3) hypercube-resident executive, and (4) application functions. The loose coupling between modules allows modification of a particular module without significantly affecting the other modules in the system. In order to enhance hypercube memory utilization and to allow expansion of image processing capabilities, a specialized program management method, incremental loading, was devised. To minimize data transfer between host and hypercube a data management method which distributes, redistributes, and tracks data set information was implemented.

    The Planning Execution Monitoring (PEM) architecture is a design concept for developing autonomous cockpit command and control software. The PEM architecture is designed to reduce the operations costs in the space transportation system through the use of automation while improving safety and operability of the system. Specifically, the PEM autonomous framework enables automatic performance of many vehicle operations that would typically be performed by a human. Also, this framework supports varying levels of autonomous control, ranging from fully automatic to fully manual control. The PEM autonomous framework interfaces with the core flight software to perform flight procedures. It can either assist human operators in performing procedures or autonomously execute routine cockpit procedures based on the operational context. Most importantly, the PEM autonomous framework promotes and simplifies the capture, verification, and validation of the flight operations knowledge. Through a hierarchical decomposition of the domain knowledge, the vehicle command and control capabilities are divided into manageable functional "chunks" that can be captured and verified separately. These functional units, each of which has the responsibility to manage part of the vehicle command and control, are modular, re-usable, and extensible. Also, the functional units are self-contained and have the ability to plan and execute the necessary steps for accomplishing a task based upon the current mission state and available resources. The PEM architecture has potential for application outside the realm of spaceflight, including management of complex industrial processes, nuclear control, and control of complex vehicles such as submarines or unmanned air vehicles.

    The Neutron Science Portal at Oak Ridge National Laboratory submits jobs to the TeraGrid for remote job execution. The TeraGrid is a network of high performance computers supported by the US National Science Foundation. There are eleven partner facilities with over a petaflop of peak computing performance and sixty petabytes of long-term storage. Globus is installed on a local machine and used for job submission. The graphical user interface is produced by java coding that reads an XML file. After submission, the status of the job is displayed in a Job Information Service window which queries globus for the status. The output folder produced in the scratch directory of the TeraGrid machine is returned to the portal with globus-url-copy command that uses the gridftp servers on the TeraGrid machines. This folder is copied from the stage-in directory of the community account to the user's results directory where the output can be plotted using the portal's visualization services. The primary problem with remote job execution is diagnosing execution problems. We have daily tests of submitting multiple remote jobs from the portal. When these jobs fail on a computer, it is difficult to diagnose the problem from the globus output. Successes and problems will be presented.

    Earliest notions concerning autism (Autism Spectrum Disorders, ASD) describe the disturbance in executive functioning. Despite altered definition, executive functioning, expressed as higher cognitive skills required complex behaviors linked to the prefrontal cortex, are defective in autism. Specific difficulties in children presenting autism or verbal disabilities at executive functioning levels have been identified. Nevertheless, the developmental deficit of executive functioning in autism is highly diversified with huge individual variation and may even be absent. The aim of the present study to examine the current standing of intact executive functioning intact in ASD.

  12. Advanced Avionics Breadboard Executive Design and Implementation

    Adams, L. R.

    1972-01-01

    The advanced avionics breadboard (AAB) executive evolved from an effort to design and develop an avionics system. This executive is unique in that it supervises a triple redundant avionics computer system. Three IBM System 4 Pi/CP computers, operating synchronously and executing identical software, comprise the central processors which route data to and from a data bus via an input/output controller. The executive's basic function is to provide application programs with an efficient software structure within which to perform specific avionics application tasks. Although implemented in a triplex data management system, the AAB executive contains the flexibility to be adapted to other systems with minimal change.

    Introduction Polio eradication is now feasible after removal of Nigeria from the list of endemic countries and global reduction of cases of wild polio virus in 2015 by more than 80%. However, all countries must remain focused to achieve eradication. In August 2015, the Catholic bishops in Kenya called for boycott of a polio vaccination campaign citing safety concerns with the polio vaccine. We conducted a survey to establish if the coverage was affected by the boycott. Methods A cross sectional survey was conducted in all the 32 counties that participated in the campaign. A total of 90,157 children and 37,732 parents/guardians were sampled to determine the vaccination coverage and reasons for missed vaccination. Results The national vaccination coverage was 93% compared to 94% in the November 2014 campaign. The proportion of parents/guardians that belonged to Catholic Church was 31% compared to 7% of the children who were missed. Reasons for missed vaccination included house not being visited (44%), children not being at home at time of visit (38%), refusal by parents (12%), children being as leep (1%), and various other reasons (5%). Compared to the November 2014 campaign, the proportion of children who were not vaccinated due to parent's refusal significantly increased from 6% to 12% in August 2015. Conclusion The call for boycott did not affect the campaign significantly. However, if the call for boycott is repeated in future it could have some significant negative implication to polio eradication. It is therefore important to ensure that any vaccine safety issues are addressed accordingly. PMID:27642458

    Smith, Warren; Hu, Chaumin

    2004-01-01

    This paper describes the design and implementation of the IPG Execution Service that reliably executes complex jobs on a computational grid. Our Execution Service is part of the IPG service architecture whose goal is to support location-independent computing. In such an environment, once n user ports an npplicntion to one or more hardware/software platfrms, the user can describe this environment to the grid the grid can locate instances of this platfrm, configure the platfrm as required for the application, and then execute the application. Our Execution Service runs jobs that set up such environments for applications and executes them. These jobs consist of a set of tasks for executing applications and managing data. The tasks have user-defined starting conditions that allow users to specih complex dependencies including task to execute when tasks fail, afiequent occurrence in a large distributed system, or are cancelled. The execution task provided by our service also configures the application environment exactly as specified by the user and captures the exit code of the application, features that many grid execution services do not support due to dflculties interfacing to local scheduling systems.

  16. SOFIA: flight planning and execution

    NASA Astrophysics Data System (ADS)

    Leppik, K.

    2016-09-01

    The Stratospheric Observatory For Infrared Astronomy (SOFIA) is a 2.5-m telescope mounted inside of a Boeing 747SP. Planning and executing astronomical observations from an aircraft moving at 500 miles per hour has its own unique challenges and advantages. Scheduling and optimizing an entire year of science observations is a balancing act with target availability, instrument availability, and operational constraints. A SOFIA flight is well choreographed, and successfully executing observations on SOFIA requires many systems and people to work together- from the telescope assembly compensating for the continual vibration and movement of the plane in order to accurately point the telescope, the expertise of the telescope operators to prepare the telescope for use by the instrument operators, aircraft operations ensuring that the aircraft is ready for flight, and the mission systems control computers keeping track of all the data. In this paper we will discuss what it takes to plan a SOFIA flight, and what we do once we're in the air. We will share a typical science flight, as well as more challenging and unique observations that require SOFIA being in the right place at the right time.

  17. Executable Architecture Research at Old Dominion University

    Tolk, Andreas; Shuman, Edwin A.; Garcia, Johnny J.

    2011-01-01

    Executable Architectures allow the evaluation of system architectures not only regarding their static, but also their dynamic behavior. However, the systems engineering community do not agree on a common formal specification of executable architectures. To close this gap and identify necessary elements of an executable architecture, a modeling language, and a modeling formalism is topic of ongoing PhD research. In addition, systems are generally defined and applied in an operational context to provide capabilities and enable missions. To maximize the benefits of executable architectures, a second PhD effort introduces the idea of creating an executable context in addition to the executable architecture. The results move the validation of architectures from the current information domain into the knowledge domain and improve the reliability of such validation efforts. The paper presents research and results of both doctoral research efforts and puts them into a common context of state-of-the-art of systems engineering methods supporting more agility.

  5. Scalable asynchronous execution of cellular automata

    NASA Astrophysics Data System (ADS)

    Folino, Gianluigi; Giordano, Andrea; Mastroianni, Carlo

    2016-10-01

    The performance and scalability of cellular automata, when executed on parallel/distributed machines, are limited by the necessity of synchronizing all the nodes at each time step, i.e., a node can execute only after the execution of the previous step at all the other nodes. However, these synchronization requirements can be relaxed: a node can execute one step after synchronizing only with the adjacent nodes. In this fashion, different nodes can execute different time steps. This can be a notable advantageous in many novel and increasingly popular applications of cellular automata, such as smart city applications, simulation of natural phenomena, etc., in which the execution times can be different and variable, due to the heterogeneity of machines and/or data and/or executed functions. Indeed, a longer execution time at a node does not slow down the execution at all the other nodes but only at the neighboring nodes. This is particularly advantageous when the nodes that act as bottlenecks vary during the application execution. The goal of the paper is to analyze the benefits that can be achieved with the described asynchronous implementation of cellular automata, when compared to the classical all-to-all synchronization pattern. The performance and scalability have been evaluated through a Petri net model, as this model is very useful to represent the synchronization barrier among nodes. We examined the usual case in which the territory is partitioned into a number of regions, and the computation associated with a region is assigned to a computing node. We considered both the cases of mono-dimensional and two-dimensional partitioning. The results show that the advantage obtained through the asynchronous execution, when compared to the all-to-all synchronous approach is notable, and it can be as large as 90% in terms of speedup.

  2. Expected Utility Distributions for Flexible, Contingent Execution

    NASA Technical Reports Server (NTRS)

    Bresina, John L.; Washington, Richard

    2000-01-01

    This paper presents a method for using expected utility distributions in the execution of flexible, contingent plans. A utility distribution maps the possible start times of an action to the expected utility of the plan suffix starting with that action. The contingent plan encodes a tree of possible courses of action and includes flexible temporal constraints and resource constraints. When execution reaches a branch point, the eligible option with the highest expected utility at that point in time is selected. The utility distributions make this selection sensitive to the runtime context, yet still efficient. Our approach uses predictions of action duration uncertainty as well as expectations of resource usage and availability to determine when an action can execute and with what probability. Execution windows and probabilities inevitably change as execution proceeds, but such changes do not invalidate the cached utility distributions, thus, dynamic updating of utility information is minimized.

  7. The Black Executive: A Challenge for Psychiatry

    PubMed Central

    Boone, Lillian Ruth

    1982-01-01

    The task of developing a body of knowledge about specific problems, both intrapsychic and psychosocial, which influence a black executive's maturation, must be initiated. There is currently a definite interest, among black executives, in obtaining access to appropriate psychotherapeutic intervention. A psychobiographical approach facilitates development of a construct for analysis of, and insight into, transference phenomena that translate into organization based behavioral responses to the black executive. Analysis of frequently encountered organizational ethos and also stimulus-response mechanisms in the black executive lead to formulation of viable conclusions for resolution of conflict. Modes of recognition of specific conflict with authority in the black executive psychotherapy patient include examination of (1) defense mechanisms frequently encountered in response to authority conflicts, (2) stated intentions of the patient in relation to career development, and (3) the affective stance of the patient. Psychobiographical issues very often have a direct developmental influence on black familial conceptualizations of authority. Childrearing practices and parentally based ego ideals and other aspects of development are linked to analogues in adult human behavior frequently observed among black executives. Suggestions for therapeutic directions involve affective and thematic strategies, all contingent upon a productive, informed, therapeutic effort. The therapeutic relationship is a most important element in the treatment strategy with the black executive. PMID:7120460

  8. Testing Flight Systems with Machine Executable Scripts

    Gibbs, Don; Bone, Brian

    2009-01-01

    The MSAP project at JPL has been testing spacecraft avionics and flight software since 2005, in part using computer executable scripts. The scripts are document files of a common word processor and comply with the format of a traditional, formal test procedure common at JPL. These procedures use keywords to issue commands and evaluate responses, mimicking a human test operator. In effect, script lines are inserted into a normal procedure. Even though the executable structure of the procedures is limited to linear sequences of fairly simple operations, we have found significant value in certain test regimes given the repeatability, ease of execution, and readily understandable intent of these procedures.

  9. Social inappropriateness, executive control, and aging.

    PubMed

    Henry, Julie D; von Hippel, William; Baynes, Kate

    2009-03-01

    Age-related deficits in executive control might lead to socially inappropriate behavior if they compromise the ability to withhold inappropriate responses. Consistent with this possibility, older adults in the current study showed greater social inappropriateness than younger adults--as rated by their peers--and this effect was mediated by deficits in executive control as well as deficits in general cognitive ability. Older adults also responded with greater social inappropriateness to a provocative event in the laboratory, but this effect was unrelated to executive functioning or general cognitive ability. These findings suggest that changes in both social and cognitive factors are important in understanding age-related changes in social behavior.

    Smith, Tyler Barratt; Perry, James Thomas

    2012-06-01

    The purpose of the Dual Compile Strategy is to increase our trust in the Compute Engine during its execution of instructions. This is accomplished by introducing a heterogeneous Monitor Engine that checks the execution of the Compute Engine. This leads to the production of a second and custom set of instructions designed for monitoring the execution of the Compute Engine at runtime. This use of multiple engines differs from redundancy in that one engine is working on the application while the other engine is monitoring and checking in parallel instead of both applications (and engines) performing the same work at the same time.

  11. Nurse executives' perspectives on succession planning.

    PubMed

    Beyers, Marjorie

    2006-06-01

    Six nurse executives from 5 settings were interviewed to learn more about how succession planning is being applied in today's practice. Their experiences, presented in this article, provide a snapshot of ways succession planning can be applied in different organizations. Interviewees share their personal philosophy, concepts, and approaches to succession planning. Although these nurse executives approach succession planning differently, they share a belief that succession planning is embedded in the nurse executive role and that succession planning is key to sustaining quality nursing practice. Insights and recommendations for further study of succession planning are summarized.

  20. Exact and Approximate Probabilistic Symbolic Execution

    NASA Technical Reports Server (NTRS)

    Luckow, Kasper; Pasareanu, Corina S.; Dwyer, Matthew B.; Filieri, Antonio; Visser, Willem

    2014-01-01

    Probabilistic software analysis seeks to quantify the likelihood of reaching a target event under uncertain environments. Recent approaches compute probabilities of execution paths using symbolic execution, but do not support nondeterminism. Nondeterminism arises naturally when no suitable probabilistic model can capture a program behavior, e.g., for multithreading or distributed systems. In this work, we propose a technique, based on symbolic execution, to synthesize schedulers that resolve nondeterminism to maximize the probability of reaching a target event. To scale to large systems, we also introduce approximate algorithms to search for good schedulers, speeding up established random sampling and reinforcement learning results through the quantification of path probabilities based on symbolic execution. We implemented the techniques in Symbolic PathFinder and evaluated them on nondeterministic Java programs. We show that our algorithms significantly improve upon a state-of- the-art statistical model checking algorithm, originally developed for Markov Decision Processes.

    A faithful execution system includes system memory, a target processor, and protection engine. The system memory stores a ciphertext including value fields and integrity fields. The value fields each include an encrypted executable instruction and the integrity fields each include an encrypted integrity value for determining whether a corresponding one of the value fields has been modified. The target processor executes plaintext instructions decoded from the ciphertext while the protection engine is coupled between the system memory and the target processor. The protection engine includes logic to retrieve the ciphertext from the system memory, decrypt the value fields into the plaintext instructions, perform an integrity check based on the integrity fields to determine whether any of the corresponding value fields have been modified, and provide the plaintext instructions to the target processor for execution.

    2015-01-01

    A better understanding of the functioning of the brain, particularly executive functions, of the prison population could aid in reducing crime rates through the reduction of recidivism rates. Indeed, reoffending appears to be related to executive dysfunction and it is known that executive functions are crucial for self-regulation. In the current paper, studies to executive functions in regular adult prisoners compared to non-offender controls were reviewed. Seven studies were found. Specific executive functions were found to be impaired in the general prison population, i.e., attention and set-shifting, as well as in separate subgroups of violent (i.e., set-shifting and working memory) and non-violent offenders (i.e., inhibition, working memory and problem solving). We conclude that the limited number of studies is remarkable, considering the high impact of this population on society and elaborate on the implications of these specific impairments that were found. Further empirical research is suggested, measuring executive functioning within subjects over time for a group of detainees as well as a control group. PMID:25688221

    Filieri, Antonio; Pasareanu, Corina S.; Visser, Willem; Geldenhuys, Jaco

    2014-01-01

    Symbolic execution techniques have been proposed recently for the probabilistic analysis of programs. These techniques seek to quantify the likelihood of reaching program events of interest, e.g., assert violations. They have many promising applications but have scalability issues due to high computational demand. To address this challenge, we propose a statistical symbolic execution technique that performs Monte Carlo sampling of the symbolic program paths and uses the obtained information for Bayesian estimation and hypothesis testing with respect to the probability of reaching the target events. To speed up the convergence of the statistical analysis, we propose Informed Sampling, an iterative symbolic execution that first explores the paths that have high statistical significance, prunes them from the state space and guides the execution towards less likely paths. The technique combines Bayesian estimation with a partial exact analysis for the pruned paths leading to provably improved convergence of the statistical analysis. We have implemented statistical symbolic execution with in- formed sampling in the Symbolic PathFinder tool. We show experimentally that the informed sampling obtains more precise results and converges faster than a purely statistical analysis and may also be more efficient than an exact symbolic analysis. When the latter does not terminate symbolic execution with informed sampling can give meaningful results under the same time and memory limits.

  14. The Wild West of executive coaching.

    PubMed

    Sherman, Stratford; Freas, Alyssa

    2004-11-01

    Annual spending on executive coaching in the United States is estimated at 1 billion dollars. Yet information about coaching's effectiveness is scarce and unreliable. No one has yet demonstrated conclusively what qualifies an executive coach or what makes one approach to executive coaching better than another. Barriers to entry are nonexistent--many executive coaches know little about business, and some know little about coaching. The coaching certifications offered by various self-appointed bodies are difficult to assess, and methods of measuring return on investment are questionable. But strategic coaching can provide critical help both to individuals and to organizations. In this article, Stratford Sherman, a senior vice president of Executive Coaching Network, and Alyssa Freas, the founder and CEO, explore the popularity of executive coaching and investigate ways to make the most of the experience. They argue that coaching is inevitably a triangular relationship between the client, the "coachee," and the coach. Its purpose is to produce behavioral change and growth in the coachee for the economic benefit of the client. The best way to maximize the likelihood of good results is to qualify all the people involved. Even so, many triangular relationships continue to generate conflict among all three parties. At the most basic level, coaches serve as suppliers of candor, providing leaders with the objective feedback they need to nourish their growth. Coaching gets executives to slow down, gain awareness, and notice the effects of their words and actions. On a larger scale, the best coaching fosters cultural change for the benefit of the entire organization. It provides a disciplined way for businesses to deepen relationships with their most valued employees while also increasing their effectiveness.

  15. Toward Synthesizing Executable Models in Biology

    PubMed Central

    Fisher, Jasmin; Piterman, Nir; Bodik, Rastislav

    2014-01-01

    Over the last decade, executable models of biological behaviors have repeatedly provided new scientific discoveries, uncovered novel insights, and directed new experimental avenues. These models are computer programs whose execution mechanistically simulates aspects of the cell’s behaviors. If the observed behavior of the program agrees with the observed biological behavior, then the program explains the phenomena. This approach has proven beneficial for gaining new biological insights and directing new experimental avenues. One advantage of this approach is that techniques for analysis of computer programs can be applied to the analysis of executable models. For example, one can confirm that a model agrees with experiments for all possible executions of the model (corresponding to all environmental conditions), even if there are a huge number of executions. Various formal methods have been adapted for this context, for example, model checking or symbolic analysis of state spaces. To avoid manual construction of executable models, one can apply synthesis, a method to produce programs automatically from high-level specifications. In the context of biological modeling, synthesis would correspond to extracting executable models from experimental data. We survey recent results about the usage of the techniques underlying synthesis of computer programs for the inference of biological models from experimental data. We describe synthesis of biological models from curated mutation experiment data, inferring network connectivity models from phosphoproteomic data, and synthesis of Boolean networks from gene expression data. While much work has been done on automated analysis of similar datasets using machine learning and artificial intelligence, using synthesis techniques provides new opportunities such as efficient computation of disambiguating experiments, as well as the ability to produce different kinds of models automatically from biological data.

  2. Musical expertise, bilingualism, and executive functioning.

    PubMed

    Bialystok, Ellen; Depape, Anne-Marie

    2009-04-01

    The authors investigated whether intensive musical experience leads to enhancements in executive processing, as has been shown for bilingualism. Young adults who were bilinguals, musical performers (instrumentalists or vocalists), or neither completed 3 cognitive measures and 2 executive function tasks based on conflict. Both executive function tasks included control conditions that assessed performance in the absence of conflict. All participants performed equivalently for the cognitive measures and the control conditions of the executive function tasks, but performance diverged in the conflict conditions. In a version of the Simon task involving spatial conflict between a target cue and its position, bilinguals and musicians outperformed monolinguals, replicating earlier research with bilinguals. In a version of the Stroop task involving auditory and linguistic conflict between a word and its pitch, the musicians performed better than the other participants. Instrumentalists and vocalists did not differ on any measure. Results demonstrate that extended musical experience enhances executive control on a nonverbal spatial task, as previously shown for bilingualism, but also enhances control in a more specialized auditory task, although the effect of bilingualism did not extend to that domain.

  3. Components of executive functioning in metamemory.

    PubMed

    Mäntylä, Timo; Rönnlund, Michael; Kliegel, Matthias

    2010-10-01

    This study examined metamemory in relation to three basic executive functions (set shifting, working memory updating, and response inhibition) measured as latent variables. Young adults (Experiment 1) and middle-aged adults (Experiment 2) completed a set of executive functioning tasks and the Prospective and Retrospective Memory Questionnaire (PRMQ). In Experiment 1, source recall and face recognition tasks were included as indicators of objective memory performance. In both experiments, analyses of the executive functioning data yielded a two-factor solution, with the updating and inhibition tasks constituting a common factor and the shifting tasks a separate factor. Self-reported memory problems showed low predictive validity, but subjective and objective memory performance were related to different components of executive functioning. In both experiments, set shifting, but not updating and inhibition, was related to PRMQ, whereas source recall showed the opposite pattern of correlations in Experiment 1. These findings suggest that metamemorial judgments reflect selective effects of executive functioning and that individual differences in mental flexibility contribute to self-beliefs of efficacy.

    PubMed

    Conway, Anne; Stifter, Cynthia A

    2012-01-01

    Despite an extensive history underscoring the role of social processes and child contributions to the development of executive functions (C. Lewis & J. Carpendale, 2009; L. S. Vygotsky, 1987), research on these relations is sparse. To address this gap, 68 mother-child dyads were examined to determine whether maternal attention-directing behaviors (attention maintaining, attention redirection) and toddlers' temperament predicted executive processes during preschool (mean age = 4.5 years, SD = 0.46)-delay and conflict inhibition. Maternal attention maintaining was associated with high levels of conflict inhibition for inhibited and exuberant children, whereas attention redirection was associated with low levels of delay and conflict inhibition for inhibited children. Therefore, maternal attention-directing behaviors may enhance the development of executive functions but only for children with inhibited and exuberant temperaments.

  8. Direct-execution architecture for production systems

    SciTech Connect

    Underwood, W.E.; Merritt, M.J.

    1981-01-01

    In the artificial intelligence and robotics community a style of programming called event- or data-driven programming is widely used. Data-driven programs execute on a production system interpreter that is usually written in the list programming language LISP. The major inefficiencies of production systems are due to conventional computer architectures (designed for procedural programming) and the inefficiencies of LISP implementations. In this paper the authors explore the issues surrounding the design of a direct-execution architecture for production systems that might overcome some of these inefficiencies. 14 references.

  10. [Executive functioning in unipolar depression: a review].

    PubMed

    Fossati, P; Ergis, A M; Allilaire, J F

    2002-01-01

    While several neuropsychological studies have demonstrated that cognitive deficits are seen across a broad range of cognitive domains, executive deficits associated with frontal lobe dysfunction may be prominent in depression. Executive function refers to cognitive processes that control and integrate other cognitive activities such as episodic memory. These executive functions involve a set of cognitive behaviors which include: dealing with novelty, selecting strategies, inhibiting incorrect responses, monitoring performance and using feedback to adjust future responding. The measurement of executive function relies mainly on the use of neuropsychological tests known to be sensitive to frontal lobe damage such as the Wisconsin and California Card Sorting Tests, verbal fluency tests, Stroop-test, Tower of London Task and Trail Making Test. The present review focuses on studies investigating executive functions in primary unipolar depression with these neuropsychological tasks. Unipolar depressed patients mainly exhibit cognitive inhibition deficits, problem-solving impairments and planning deficits. Cognitive inhibition deficits in depressed patients have been related to a reduction of cognitive resources and psychomotor retardation. Inhibition disturbance could lead depressed patients to process irrelevant information and consequently reduce their capacity to control transient mood changes. Several studies have found evidence of problem solving impairments in depressed patients. Depressed subjects show with card sorting tests difficulties in hypothesis testing with a loss of spontaneous and reactive cognitive flexibility. The cognitive rigidity and hypothesis-testing associated with dorsolateral prefrontal dysfunction in depression may prevent patients to cope with life events and lead to a perpetuation of depressed mood by a continuation of stress exposure. Planning tasks, such as the Tower of London Test, also demonstrate that depressed patients fail to use

    Pineda, David A; Merchan, Vilma

    2003-03-01

    The aim of this article was to observe the correlation between executive function (EF) variables, and to determine the factor structure of the EF in young university students, as mathematical models for supporting its multidimensional structure. Participants were both males and females, aged 16 to 21 years (N = 100) and with normal Full Scale IQ selected in a randomized and representative approach in private universities of Medellín, Colombia. They were students of verbal, visual-spatial, and mathematical careers. An executive function assessment battery was applied and which included: Wisconsin Card Sorting Test (WCST), Trail Making Test (TMT) A and B, verbal fluency test (FAS) by phonologic and semantic cues, and Stroop's conflict word/color test. The results were as follows: An orthogonal structure of five factors, which explained 74.9% of the variance, was found. Factor 1 was formed by WCST variables (organization and flexibility), and explained 25.8% of the variance. Errors from the Stroop reading and naming were assigned to factor 2, which explained 17.3% of the variance. Factor 3 was the time for executing Stroop's test, and explained 13.1% of the variance. Factor 4 was TMT A and B (10.1%). Factor 5 was verbal fluency (8.5% of the variance). In conclusion, executive function in young university students was conformed by five orthogonal cognitive dimensions.

  4. Executive functioning and visual working memory.

    PubMed

    Lepach, Anja C; Pauls, Franz; Petermann, Franz

    2015-01-01

    The matter of modality is controversially discussed in the context of working memory (WM). There is evidence that modality-specific processes are accompanied by amodal processes to some extent. We investigated the relationship between executive-functioning tasks and visual WM (VWM) and were especially interested in the issue of amodal processes. Our correlational analyses suggest modality-independent relations of the tasks. We also aimed to quantify to what extent executive functioning is meaningful for VWM performances. We therefore estimated the relationship between executive tasks and VWM performances in a healthy (n = 710) and a clinical traumatic brain injury sample (n = 151) as well as in the combined total sample. The results indicate a substantial relevance of the verbal task for VWM performances in the total and the clinical sample but a low relevance in the healthy sample. These results could support assumptions of resource-depending differences in the relations of executive functioning and VWM but need further validation due to limitations of our study.

  12. Writing executable assertions to test flight software

    NASA Technical Reports Server (NTRS)

    Mahmood, A.; Andrews, D. M.; Mccluskey, E. J.

    1984-01-01

    An executable assertion is a logical statement about the variables or a block of code. If there is no error during execution, the assertion statement results in a true value. Executable assertions can be used for dynamic testing of software. They can be employed for validation during the design phase, and exception and error detection during the operation phase. The present investigation is concerned with the problem of writing executable assertions, taking into account the use of assertions for testing flight software. They can be employed for validation during the design phase, and for exception handling and error detection during the operation phase The digital flight control system and the flight control software are discussed. The considered system provides autopilot and flight director modes of operation for automatic and manual control of the aircraft during all phases of flight. Attention is given to techniques for writing and using assertions to test flight software, an experimental setup to test flight software, and language features to support efficient use of assertions.

  14. Exergaming immediately enhances children's executive function.

    PubMed

    Best, John R

    2012-09-01

    The current study examined an important aspect of experience--physical activity--that may contribute to children's executive function. The design attempted to tease apart 2 important aspects of children's exercise by examining the separate and combined effects of acute physical activity and cognitive engagement on an aspect of children's executive functioning. In a 2 × 2 within-subject experimental design, children (N = 33, 6 to 10 years old) completed activities that varied systematically in both physical activity (physically active video games versus sedentary video activities) and cognitive engagement (challenging and interactive video games versus repetitive video activities). Cognitive functioning, including executive function, was assessed after each activity by a modified flanker task (Rueda et al., 2004). Whereas cognitive engagement had no effect on any aspect of task performance, physical activity (i.e., exergaming) enhanced children's speed to resolve interference from conflicting visuospatial stimuli. Age comparisons indicated improvements with age in the accuracy of resolving interference and in overall response time. The results extend past research by showing more precisely how physical activity influences executive function and how this effect differs from the improvements that occur with development.

    2016-06-01

    We examined the relationship between executive functions and both factual and conceptual learning of science, specifically chemistry, in early adolescence. Sixty-three pupils in their second year of secondary school (aged 12-13 years) participated. Pupils completed tasks of working memory (Spatial Working Memory), inhibition (Stop-Signal), attention set-shifting (ID/ED), and planning (Stockings of Cambridge), from the CANTAB. They also participated in a chemistry teaching session, practical, and assessment on the topic of acids and alkalis designed specifically for this study. Executive function data were related to (1) the chemistry assessment which included aspects of factual and conceptual learning and (2) a recent school science exam. Correlational analyses between executive functions and both the chemistry assessment and science grades revealed that science achievements were significantly correlated with working memory. Linear regression analysis revealed that visuospatial working memory ability was predictive of chemistry performance. Interestingly, this relationship was observed solely in relation to the conceptual learning condition of the assessment highlighting the role of executive functions in understanding and applying knowledge about what is learned within science teaching.

    2014-10-01

    Organ procurement from executed prisoners in China is internationally condemned, yet this practice continues unabated in 2014. This is despite repeated announcements from Chinese authorities that constructive measures have been undertaken to conform to accepted ethical standards. While there is unanimous agreement on the unethical nature of using organs from executed prisoners, due to its limitations on voluntary and informed consent, there is insufficient coverage of forced organ procurement from prisoners of conscience without consent. Strategies to influence positive change in China over the last few decades have failed to bring this practice to an end. While organ donation and transplantation services in China have undergone considerable structural changes in the last few years, fundamental attempts to shift practice to ethically sourced organs have floundered. In this article, we discuss the organ trade in China, reflect upon organ procurement from executed prisoners (including both capital prisoners and prisoners of conscience) and provide an overview of contradictory Chinese efforts to halt forced organ procurement from executed prisoners. Finally, we highlight current actions being taken to address this issue and offer comprehensive recommendations to bring this ethically indefensible practice to an immediate end.

    2014-01-01

    Executive functions might be important for successful performance in sports, particularly in team sports requiring quick anticipation and adaptation to continuously changing situations in the field. The executive functions motor inhibition, attention and visuospatial working memory were examined in highly talented soccer players. Eighty-four highly talented youth soccer players (mean age 11.9), and forty-two age-matched amateur soccer players (mean age 11.8) in the age range 8 to 16 years performed a Stop Signal task (motor inhibition), the Attention Network Test (alerting, orienting, and executive attention) and a visuospatial working memory task. The highly talented soccer players followed the talent development program of the youth academy of a professional soccer club and played at the highest national soccer competition for their age. The amateur soccer players played at a regular soccer club in the same geographical region as the highly talented soccer players and play in a regular regional soccer competition. Group differences were tested using analyses of variance. The highly talented group showed superior motor inhibition as measured by stop signal reaction time (SSRT) on the Stop Signal task and a larger alerting effect on the Attention Network Test, indicating an enhanced ability to attain and maintain an alert state. No group differences were found for orienting and executive attention and visuospatial working memory. A logistic regression model with group (highly talented or amateur) as dependent variable and executive function measures that significantly distinguished between groups as predictors showed that these measures differentiated highly talented soccer players from amateur soccer players with 89% accuracy. Highly talented youth soccer players outperform youth amateur players on suppressing ongoing motor responses and on the ability to attain and maintain an alert state; both may be essential for success in soccer.

  13. Unraveling Executive Functioning in Dual Diagnosis

    PubMed Central

    Duijkers, Judith C. L. M.; Vissers, Constance Th. W. M.; Egger, Jos I. M.

    2016-01-01

    In mental health, the term dual-diagnosis is used for the co-occurrence of Substance Use Disorder (SUD) with another mental disorder. These co-occurring disorders can have a shared cause, and can cause/intensify each other’s expression. Forming a threat to health and society, dual-diagnosis is associated with relapses in addiction-related behavior and a destructive lifestyle. This is due to a persistent failure to control impulses and the maintaining of inadequate self-regulatory behavior in daily life. Thus, several aspects of executive functioning like inhibitory, shifting and updating processes seem impaired in dual-diagnosis. Executive (dys-)function is currently even seen as a shared underlying key component of most mental disorders. However, the number of studies on diverse aspects of executive functioning in dual-diagnosis is limited. In the present review, a systematic overview of various aspects of executive functioning in dual-diagnosis is presented, striving for a prototypical profile of patients with dual-diagnosis. Looking at empirical results, inhibitory and shifting processes appear to be impaired for SUD combined with schizophrenia, bipolar disorder or cluster B personality disorders. Studies involving updating process tasks for dual-diagnosis were limited. More research that zooms in to the full diversity of these executive functions is needed in order to strengthen these findings. Detailed insight in the profile of strengths and weaknesses that underlies one’s behavior and is related to diagnostic classifications, can lead to tailor-made assessment and indications for treatment, pointing out which aspects need attention and/or training in one’s self-regulative abilities.

  15. Executive leadership and superpower arms control

    SciTech Connect

    Baglione, L.A.

    1992-01-01

    This dissertation addresses the conditions that led the superpowers to undertake negotiations to limit weapons and sometimes conclude accords. This thesis presents a fourth approach. The leadership model emphasizes the executive-the Soviet general secretary and the American president-as the pivotal actor in arms control decision-making. The executive's perception of the source and level of threat consistently defines his preferred bargaining strategy, and domestic constraints on executive authority account for deviations from that approach. When he has considerable authority, the executive is able to pursue his preferred policy, but when the leader lacks power, other institutional actors within the domestic political system constrain the leader. To test the leadership model, the thesis examines four cases of American and Soviet arms control decision-making: the test ban talks of the late 1950s, the negotiations for the Limited Test Ban Treaty in 1963, the intermediate nuclear forces discussions of the 1980s, and the last phase of the START negotiations from 1989 to 1991. In each of these case studies, the dissertation juxtaposes the leadership model with the previously accepted approaches to evaluate which explanation best conforms to the evidence. The case studies demonstrated the superiority of the leadership model. Neither the balance of power, the desire to strengthen stability, nor the bureaucratic order adequately accounts for arms control decision-making. Instead, the leader's perception f the threat and opportunity determined the nation's approach to the negotiations. Only concerns about coalition maintenance served to temper the executive's tack at the bargaining table.

  18. From an Executive Network to Executive Control: A Computational Model of the N-back Task

    Chatham, Christopher H.; Herd, Seth A.; Brant, Angela M.; Hazy, Thomas E.; Miyake, Akira; O’Reilly, Randy; Friedman, Naomi P.

    2011-01-01

    A paradigmatic test of executive control, the n-back task, is known to recruit a widely-distributed parietal, frontal and striatal “executive network,” and is thought to require an equally wide array of executive functions. The mapping of functions onto substrates in such a complex task presents a significant challenge to any theoretical framework for executive control. To address this challenge, we developed a biologically-constrained model of the n-back task that emergently develops the ability to appropriately gate, bind, and maintain information in working memory in the course of learning to perform the task. Furthermore, the model is sensitive to proactive interference in ways that match findings from neuroimaging, and shows a U-shaped performance curve after manipulation of prefrontal dopaminergic mechanisms similar to that observed in studies of genetic polymorphisms and pharmacological manipulations. Our model represents a formal computational link between anatomical, functional neuroimaging, genetic, behavioral, and theoretical levels of analysis in the study of executive control. In addition, the model specifies one way in which the prefrontal cortex, basal ganglia, parietal, and sensory cortices may learn to cooperate and give rise to executive control. PMID:21563882

  10. Infant Attention and Early Childhood Executive Function

    PubMed Central

    Cuevas, Kimberly; Bell, Martha Ann

    2013-01-01

    Individual differences in infant attention are theorized to reflect the speed of information processing and are related to later cognitive abilities (i.e., memory, language, intelligence). This study provides the first systematic longitudinal analysis of infant attention and early childhood executive function (EF; e.g., working memory, inhibitory control, cognitive flexibility). A group of 5-month-olds (n = 201) were classified as short or long lookers. At 24, 36, and 48 months of age, children completed age-appropriate EF tasks. Infant short lookers (i.e., more efficient information processors) exhibited higher EF throughout early childhood as compared to infant long lookers, even after controlling for verbal ability (a potential indicator of intelligence). These findings are discussed in relation to the emergence of executive attention. PMID:23711103

    1989-05-01

    Remote Procedure Execution facilitates the construction of distributed software systems, spanning computers of various types. Programmers who use the RPX package specify subroutine calls which are to be executed on a remote computer. RPX is used to generate code for dummy routines which transmit input parameters and receive output parameters, as well as a main program which receives procedure call requests, calls the requested procedure, and returns the result. The package automatically performs datatype conversions and uses an appropriate connection oriented protocol. Supported operating systems/processors are VMS(VAX), UNIX(MIPS R2000, R3000) and Software Components Group's pSOS (680x0). Connection oriented protocols are supported over Ethernet (TCP/IP) and RS232 (a package of our own design). 2 refs., 2 figs.

  13. Early executive function predicts reasoning development.

    PubMed

    Richland, Lindsey E; Burchinal, Margaret R

    2013-01-01

    Analogical reasoning is a core cognitive skill that distinguishes humans from all other species and contributes to general fluid intelligence, creativity, and adaptive learning capacities. Yet its origins are not well understood. In the study reported here, we analyzed large-scale longitudinal data from the Study of Early Child Care and Youth Development to test predictors of growth in analogical-reasoning skill from third grade to adolescence. Our results suggest an integrative resolution to the theoretical debate regarding contributory factors arising from smaller-scale, cross-sectional experiments on analogy development. Children with greater executive-function skills (both composite and inhibitory control) and vocabulary knowledge in early elementary school displayed higher scores on a verbal analogies task at age 15 years, even after adjusting for key covariates. We posit that knowledge is a prerequisite to analogy performance, but strong executive-functioning resources during early childhood are related to long-term gains in fundamental reasoning skills.

  14. Development of the Executive Personal Finance Scale.

    Spinella, Marcello; Yang, Bijou; Lester, David

    2007-03-01

    There is accumulating evidence that prefrontal systems play an important role in management of personal finances, based on studies using clinical populations, functional neuroimaging, and both subjective and objective neuropsychological measures. This study developed the Executive Personal Finance Scale (EPFS) as a specific self-rating measure of executive aspects of personal money management. The resulting 20-item scale had good reliability and showed four factors: impulse control, organization, planning, and motivational drive. Validity was evidenced by correlations with income, credit card debt, and investments. The EPFS also showed logical correlations with compulsive buying and money attitudes. Second-order factor analysis of the EPFS and other scales revealed two higher-order factors of personal finance: cognitive (e.g., planning, organizing) and emotional (e.g., anxiety, impulse-spending, prestige). The EPFS shows good psychometric properties, is easy to use, and will make a convenient complement to other research methodologies exploring the neural basis of personal finance management.

    The Task Control Architecture (TCA) provides communication and coordination facilities to construct distributed, concurrent robotic systems. The use of TCA in a system that walks a legged robot through rugged terrain is described. The walking system, as originally implemented, had a sequential sense-plan-act control cycle. Utilizing TCA features for task sequencing and monitoring, the system was modified to concurrently plan and execute steps. Walking speed improved by over 30 percent, with only a relatively modest conversion effort.

  20. Cognitive programs: software for attention's executive

    PubMed Central

    Tsotsos, John K.; Kruijne, Wouter

    2014-01-01

    What are the computational tasks that an executive controller for visual attention must solve? This question is posed in the context of the Selective Tuning model of attention. The range of required computations go beyond top-down bias signals or region-of-interest determinations, and must deal with overt and covert fixations, process timing and synchronization, information routing, memory, matching control to task, spatial localization, priming, and coordination of bottom-up with top-down information. During task execution, results must be monitored to ensure the expected results. This description includes the kinds of elements that are common in the control of any kind of complex machine or system. We seek a mechanistic integration of the above, in other words, algorithms that accomplish control. Such algorithms operate on representations, transforming a representation of one kind into another, which then forms the input to yet another algorithm. Cognitive Programs (CPs) are hypothesized to capture exactly such representational transformations via stepwise sequences of operations. CPs, an updated and modernized offspring of Ullman's Visual Routines, impose an algorithmic structure to the set of attentional functions and play a role in the overall shaping of attentional modulation of the visual system so that it provides its best performance. This requires that we consider the visual system as a dynamic, yet general-purpose processor tuned to the task and input of the moment. This differs dramatically from the almost universal cognitive and computational views, which regard vision as a passively observing module to which simple questions about percepts can be posed, regardless of task. Differing from Visual Routines, CPs explicitly involve the critical elements of Visual Task Executive (vTE), Visual Attention Executive (vAE), and Visual Working Memory (vWM). Cognitive Programs provide the software that directs the actions of the Selective Tuning model of visual

    The genetic basis of resilience, defined as better cognitive functioning than predicted based on neuroimaging or neuropathology, is not well understood. Our objective was to identify genetic variation associated with executive functioning resilience. We computed residuals from regression models of executive functioning, adjusting for age, sex, education, Hachinski score, and MRI findings (lacunes, cortical thickness, volumes of white matter hyperintensities and hippocampus). We estimated heritability and analyzed these residuals in models for each SNP. We further evaluated our most promising SNP result by evaluating cis-associations with brain levels of nearby (±100 kb) genes from a companion data set, and comparing expression levels in cortex and cerebellum from decedents with AD with those from other non-AD diseases. Complete data were available for 750 ADNI participants of European descent. Executive functioning resilience was highly heritable (H² = 0.76; S.E. = 0.44). rs3748348 on chromosome 14 in the region of RNASE13 was associated with executive functioning resilience (p-value = 4.31 × 10⁻⁷). rs3748348 is in strong linkage disequilibrium (D' of 1.00 and 0.96) with SNPs that map to TPPP2, a member of the α-synuclein family of proteins. We identified nominally significant associations between rs3748348 and expression levels of three genes (FLJ10357, RNASE2, and NDRG2). The strongest association was for FLJ10357 in cortex, which also had the most significant difference in expression between AD and non-AD brains, with greater expression in cortex of decedents with AD (p-value = 7 × 10⁻⁷). Further research is warranted to determine whether this signal can be replicated and whether other loci may be associated with cognitive resilience.

  3. Recovering from execution errors in SIPE

    NASA Technical Reports Server (NTRS)

    Wilkins, D. E.

    1987-01-01

    In real-world domains (e.g., a mobile robot environment), things do not always proceed as planned, so it is important to develop better execution-monitoring techniques and replanning capabilities. These capabilities in the SIPE planning system are described. The motivation behind SIPE is to place enough limitations on the representation so that planning can be done efficiently, while retaining sufficient power to still be useful. This work assumes that new information given to the execution monitor is in the form of predicates, thus avoiding the difficult problem of how to generate these predicates from information provided by sensors. The replanning module presented here takes advantage of the rich structure of SIPE plans and is intimately connected with the planner, which can be called as a subroutine. This allows the use of SIPE's capabilities to determine efficiently how unexpected events affect the plan being executed and, in many cases, to retain most of the original plan by making changes in it to avoid problems caused by these unexpected events. SIPE is also capable of shortening the original plan when serendipitous events occur. A general set of replanning actions is presented along with a general replanning capability that has been implemented by using these actions.

  4. Diagnosing faults in autonomous robot plan execution

    Lam, Raymond K.; Doshi, Rajkumar S.; Atkinson, David J.; Lawson, Denise M.

    1989-01-01

    A major requirement for an autonomous robot is the capability to diagnose faults during plan execution in an uncertain environment. Many diagnostic researches concentrate only on hardware failures within an autonomous robot. Taking a different approach, the implementation of a Telerobot Diagnostic System that addresses, in addition to the hardware failures, failures caused by unexpected event changes in the environment or failures due to plan errors, is described. One feature of the system is the utilization of task-plan knowledge and context information to deduce fault symptoms. This forward deduction provides valuable information on past activities and the current expectations of a robotic event, both of which can guide the plan-execution inference process. The inference process adopts a model-based technique to recreate the plan-execution process and to confirm fault-source hypotheses. This technique allows the system to diagnose multiple faults due to either unexpected plan failures or hardware errors. This research initiates a major effort to investigate relationships between hardware faults and plan errors, relationships which were not addressed in the past. The results of this research will provide a clear understanding of how to generate a better task planner for an autonomous robot and how to recover the robot from faults in a critical environment.

  6. Intelligence and executive functions in frontotemporal dementia

    Roca, María; Manes, Facundo; Gleichgerrcht, Ezequiel; Watson, Peter; Ibáñez, Agustín; Thompson, Russell; Torralva, Teresa; Duncan, John

    2013-01-01

    Recently (Roca et al. (2010), we used the relationship with general intelligence (Spearman’s g) to define two sets of frontal lobe or “executive” tests. For one group, including Wisconsin card sorting and verbal fluency, reduction in g entirely explained the deficits found in frontal patients. For another group, including tests of social cognition and multitasking, frontal deficits remained even after correction for g. Preliminary evidence suggested a link of the latter tasks to more anterior frontal regions. Here we develop this distinction in the context of behavioural-variant frontotemporal dementia (bvFTD), a disorder which progressively affects frontal lobe cortices. In bvFTD, some executive tests, including tests of social cognition and multitasking, decline from the early stage of the disease, while others, including classical executive tests such as Wisconsin card sorting, verbal fluency or Trail Making Test part B, show deficits only later on. Here we show that, while deficits in the classical executive tests are entirely explained by g, deficits in the social cognition and multitasking tests are not. The results suggest a relatively selective cognitive deficit at mild stages of the disease, followed by more widespread cognitive decline well predicted by g. PMID:23347963

  7. Executive function disorders: rehabilitation challenges and strategies.

    PubMed

    Mateer, C A

    1999-01-01

    Individuals with frontal lobe impairments often demonstrate a variety of disorders of executive function that pose significant challenges to rehabilitation. Impairments in initiation, sequencing, impulse control, attention, prospective memory, and self-awareness frequently manifest in disorganized and maladaptive behaviors that severely impact many aspects of adaptive functioning. A greater awareness of the nature of these deficits, improved tools for evaluation, and an increased interest in rehabilitation have led to the development of both specific strategies and general schemas for treating and managing executive function deficits. Studies supporting the use of environmental manipulations, compensatory strategy training, and techniques to improve underlying skills, including attention and prospective memory, are described. An overarching strategy for working with individuals with impaired executive functions is proposed, based on the individual's level of awareness and context dependency. Rehabilitation is conceptualized as a set of activities, which assist the individual in moving from a more dependent, externally supported state to a more independent, internally supported and self-regulated state through the systematic shift in external to internal regulation of behavior. Successful movement along this continuum is variable across cases, but the literature suggests that significant gains in function and behavior are possible.

  8. Can Rhesus Monkey Learn Executive Attention?

    PubMed Central

    Bramlett-Parker, Jessica; Washburn, David A.

    2016-01-01

    A growing body of data indicates that, compared to humans, rhesus monkeys perform poorly on tasks that assess executive attention, or voluntary control over selection for processing, particularly under circumstances in which attention is attracted elsewhere by competing stimulus control. In the human-cognition literature, there are hotly active debates about whether various competencies such as executive attention, working memory capacity, and fluid intelligence can be improved through training. In the current study, rhesus monkeys (Macaca mulatta) completed an attention-training intervention including several inhibitory-control tasks (a Simon task, numerical Stroop task, global/local interference task, and a continuous performance task) to determine whether generalized improvements would be observed on a version of the Attention Network Test (ANT) of controlled attention, which was administered before and after the training intervention. Although the animals demonstrated inhibition of prepotent responses and improved in executive attention with practice, this improvement did not generalize to the ANT at levels consistently better than were observed for control animals. Although these findings fail to encourage the possibility that species differences in cognitive competencies can be ameliorated through training, they do advance our understanding of the competition between stimulus-control and cognitive-control in performance by nonhuman and human primates.

  14. Differentiating the Bishop ash bed and related tephra layers by elemental-based similarity coefficients of volcanic glass shards using solution inductively coupled plasma-mass spectrometry (S-ICP-MS)

    Volcanic glass samples from the same volcanic center (intra-source) often have a similar major-element composition. Thus, it can be difficult to distinguish between individual tephra layers, particularly when using similarity coefficients calculated from electron microprobe major-element measurements. Minor/trace element concentrations in glass can be determined by solution inductively coupled plasma mass spectrometry (S-ICP-MS), but have not been shown as suitable for use in large tephrochronologic databases. Here, we present minor/trace-element concentrations measured by S-ICP-MS and compare these data by similarity coefficients, the method commonly used in large databases. Trial samples from the Bishop Tuff, the upper and lower tuffs of Glass Mountain and the tuffs of Mesquite Spring suites from eastern California, USA, which have an indistinguishable major-element composition, were analyzed using S-ICP-MS. The resulting minor/trace element similarity coefficients clearly separated the suites of tephra layers and, in most cases, individual tephra layers within each suite. Comparisons with previous instrumental neutron activation analysis (INAA) elemental measurements were marginally successful. This is important step toward quantitative correlation in large tephrochronologic databases to achieve definitive identification of volcanic glass samples and for high-resolution age determinations. ?? 2007 Elsevier Ltd and INQUA.

  15. Commentary: Mentoring the mentor: executive coaching for clinical departmental executive officers.

    PubMed

    Geist, Lois J; Cohen, Michael B

    2010-01-01

    Departmental executive officers (DEOs), department chairs, and department heads in medical schools are often hired on the basis of their accomplishments in research as well as their skills in administration, management, and leadership. These individuals are also expected to be expert in multiple areas, including negotiation, finance and budgeting, mentoring, and personnel management. At the same time, they are expected to maintain and perhaps even enhance their personal academic standing for the purposes of raising the level of departmental and institutional prestige and for recruiting the next generation of physicians and scientists. In the corporate world, employers understand the importance of training new leaders in requisite skill enhancement that will lead to success in their new positions. These individuals are often provided with extensive executive training to develop the necessary competencies to make them successful leaders. Among the tools employed for this purpose are the use of personal coaches or executive training courses. The authors propose that the use of executive coaching in academic medicine may be of benefit for new DEOs. Experience using an executive coach suggests that this was a valuable growth experience for new leaders in the institution.

  16. Motor preparation, motor execution, attention, and executive functions in attention deficit/hyperactivity disorder (ADHD).

    2005-04-01

    Attention and executive functions were investigated in medicated and unmedicated children with ADHD combined type using a novel selective reaching task. This task involved responding as rapidly as possible to a target while at times having to ignore a distractor. Results indicated that unmedicated children with ADHD showed slow and inaccurate responding. Slow responding reflected problems at the stage of movement preparation but not movement execution. An attentional impairment, rather than a motor planning problem per se, appeared to underlie the slow movement preparation. Inaccurate responding reflected problems with response inhibition and selective attention, impulsivity, set-shifting, and difficulties in maintaining vigilance. Although medicated children with ADHD did not show slow movement preparation, they did show some response inaccuracy, resulting especially from impulsive responding. These findings suggest that ADHD is characterized by slow motor preparation (but not motor execution), and deficits in selective attention, vigilance, and executive functions. Preliminary results suggest that stimulant medication may resolve some of these motor, attentional and executive function deficits.

  17. Ratings of Everyday Executive Functioning (REEF): A parent-report measure of preschoolers' executive functioning skills.

    2017-01-01

    Executive functioning (EF) facilitates the development of academic, cognitive, and social-emotional skills and deficits in EF are implicated in a broad range of child psychopathologies. Although EF has clear implications for early development, the few questionnaires that assess EF in preschoolers tend to ask parents for global judgments of executive dysfunction and thus do not cover the full range of EF within the preschool age group. Here we present a new measure of preschoolers' EF-the Ratings of Everyday Executive Functioning (REEF)-that capitalizes on parents' observations of their preschoolers' (i.e., 3- to 5-year-olds) behavior in specific, everyday contexts. Over 4 studies, items comprising the REEF were refined and the measure's reliability and validity were evaluated. Factor analysis of the REEF yielded 1 factor, with items showing strong internal reliability. More important, children's scores on the REEF related to both laboratory measures of EF and another parent-report EF questionnaire. Moreover, reflecting divergent validity, the REEF was more strongly related to measures of EF as opposed to measures of affective styles. The REEF also captured differences in children's executive skills across the preschool years, and norms at 6-month intervals are reported. In summary, the REEF is a new parent-report measure that provides researchers with an efficient, valid, and reliable means of assessing preschoolers' executive functioning. (PsycINFO Database Record

    2005-01-01

    NASA spacecraft and robots operate at long distances from Earth Command sequences generated manually, or by automated planners on Earth, must eventually be executed autonomously onboard the spacecraft or robot. Software systems that execute commands onboard are known variously as execution systems, virtual machines, or sequence engines. Every robotic system requires some sort of execution system, but the level of autonomy and type of control they are designed for varies greatly. This paper presents a survey of execution systems with a focus on systems relevant to NASA missions.

    1973-01-01

    A very large scale computer programming procedure called the DIALOG executive system was developed for the CDC 6000 series computers. The executive computer program, DIALOG, controls the sequence of execution and data management function for a library of independent computer programs. Communication of common information is accomplished by DIALOG through a dynamically constructed and maintained data base of common information. Each computer program maintains its individual identity and is unaware of its contribution to the large scale program. This feature makes any computer program a candidate for use with the DIALOG executive system. The installation and uses of the DIALOG executive system are described.

  20. Evaluation of a differentiation model of preschoolers' executive functions.

    2015-01-01

    Despite the prominent role of executive functions in children's emerging competencies, there remains debate regarding the structure and development of executive functions. In an attempt to reconcile these discrepancies, a differentiation model of executive function development was evaluated in the early years using 6-month age groupings. Specifically, 281 preschoolers completed measures of working memory, inhibition, and shifting. Results contradicted suggestions that executive functions follow a single trajectory of progressive separation in childhood, instead suggesting that these functions may undergo a period of integration in the preschool years. These results highlight potential problems with current practices and theorizing in executive function research.

  1. Executive Function and Emotion Regulation Strategy Use in Adolescents.

    PubMed

    Lantrip, Crystal; Isquith, Peter K; Koven, Nancy S; Welsh, Kathleen; Roth, Robert M

    2016-01-01

    Development of emotion regulation strategy use involves a transition from reliance on suppression during childhood to greater use of reappraisal in adolescence and adulthood-a transition that parallels developmental changes in executive functions. We evaluated the relationship between emotion regulation strategy use and executive functioning in the everyday life of 70 typically developing adolescents who completed the Emotion Regulation Questionnaire for Youth and the Behavior Rating Inventory of Executive Function-Self-Report. Results indicated that greater reliance on reappraisal was associated with better executive functions, while reliance on suppression was related to poorer executive functions. Findings suggest that adolescents who rely on reappraisal may have more cognitive resources to help them remain attentive and well regulated in their daily lives. On the other hand, if better executive functions facilitate the use of reappraisal, adolescents' ability to regulate their emotions could potentially be enhanced via supports for executive functions.

  2. An empirical analysis of executive behaviour with hospital executive information systems in Taiwan.

    PubMed

    Huang, Wei-Min

    2013-01-01

    Existing health information systems largely only support the daily operations of a medical centre, and are unable to generate the information required by executives for decision-making. Building on past research concerning information retrieval behaviour and learning through mental models, this study examines the use of information systems by hospital executives in medical centres. It uses a structural equation model to help find ways hospital executives might use information systems more effectively. The results show that computer self-efficacy directly affects the maintenance of mental models, and that system characteristics directly impact learning styles and information retrieval behaviour. Other results include the significant impact of perceived environmental uncertainty on scan searches; information retrieval behaviour and focused searches on mental models and perceived efficiency; scan searches on mental model building; learning styles and model building on perceived efficiency; and finally the impact of mental model maintenance on perceived efficiency and effectiveness.

  3. Lisdexamfetamine Effects on Executive Activation and Neurochemistry in Menopausal Women with Executive Function Difficulties.

    Many women with no history of executive dysfunction report difficulties in this domain during the menopause transition. Lisdexamfetamine (LDX) has been suggested to be a safe and effective treatment option for these women. However, the mechanism by which LDX improves executive functioning in these women is not known. Here we investigated the effects of LDX on brain activation and neurochemistry, hypothesizing that LDX would be associated with increased activation and decreased glutamate in executive regions. Fourteen women underwent multimodal neuroimaging at 7T at three time points in this baseline-corrected, double-blind, placebo-controlled, crossover study. Effects of LDX on symptom severity, blood-oxygen-level-dependent (BOLD) signal, and dorsolateral prefrontal cortex (DLPFC) glutamate+glutamine (Glx) were measured using a clinician-administered questionnaire, fMRI during performance of a fractal n-back task, and (1)H-MRS, respectively. The effect of treatment (LDX minus baseline vs placebo minus baseline) on these behavioral and neural markers of executive function was examined using repeated measures mixed effects models. LDX treatment was associated with decreased symptom severity, increased activation in the insula and DLPFC, and decreased DLPFC Glx. In addition, the magnitude of LDX-induced improvement in symptom severity predicted both direction and magnitude of LDX-induced change in insular and DLPFC activation. Moreover, symptom severity was positively correlated with Glx concentration in the left DLPFC at baseline. These findings provide novel evidence that the neural mechanisms by which LDX acts to improve self-reported executive functioning in healthy menopausal women with midlife onset of executive difficulties include modulation of insular and DLPFC recruitment as well as decrease in DLPFC Glx concentration.

    Marketers are under increasing scrutiny from their management to demonstrate accountability for the resources they receive. Three models are presented to help marketers execute their customer communication activities more effectively. Benefits of using the "Identification of Strategic Communication Elements," "Business Communication" and "Communications Management Process" models include (1) more effective upfront strategic and tactical planning, (2) ensuring key communication principles are addressed, (3) easier communication program communication, (4) provides a framework for program evaluation and market research and (5) increases the creative thinking marketers need when addressing the major marketing challenges. The ultimate benefit is the greater likelihood of more positive marketing results.

  6. An Executable Calculus for Service Choreography

    NASA Astrophysics Data System (ADS)

    Besana, Paolo; Barker, Adam

    The Lightweight Coordination Calculus (LCC) is a compact choreography language based on process calculus. LCC is a directly executable specification and can therefore be dynamically distributed to a group of peers for enactment at run-time; this offers flexibility and allows peers to coordinate in open systems without prior knowledge of an interaction. This paper contributes to the body of choreography research by proposing two extensions to LCC covering parallel composition and choreography abstraction. These language extensions are evaluated against a subset of the Service Interaction Patterns, a benchmark in the process modelling community.

    Executive Function (EF) refers to important socio-emotional and cognitive skills that are known to be highly correlated with both academic and life success. EF is a blanket term that is considered to include self-regulation, working memory, and planning. Recent studies have shown a relationship between EF and motor control. The emergence of motor control coincides with that of EF, hence understanding the relationship between these two domains could have significant implications for early detection and remediation of later EF deficits. The purpose of the current study was to investigate this relationship in young children. This study incorporated the Behavioral Rating Inventory of Executive Function (BRIEF) and two motor assessments with a focus on precision grasping to test this hypothesis. The BRIEF is comprised of two indices of EF: (1) the Behavioral Regulation Index (BRI) containing three subscales: Inhibit, Shift, and Emotional Control; (2) the Metacognition Index (MI) containing five subscales: Initiate, Working Memory, Plan/Organize, Organization of Materials, and Monitor. A global executive composite (GEC) is derived from the two indices. In this study, right-handed children aged 5–6 and 9–10 were asked to: grasp-to-construct (Lego® models); and grasp-to-place (wooden blocks), while their parents completed the BRIEF questionnaire. Analysis of results indicated significant correlations between the strength of right hand preference for grasping and numerous elements of the BRIEF including the BRI, MI, and GEC. Specifically, the more the right hand was used for grasping the better the EF ratings. In addition, patterns of space-use correlated with the GEC in several subscales of the BRIEF. Finally and remarkably, the results also showed a reciprocal relationship between hand and space use for grasping and EF. These findings are discussed with respect to: (1) the developmental overlap of motor and executive functions; (2) detection of EF deficits through

    The New Millennium Remote Agent (NMRA) will be the first AI system to control an actual spacecraft. The spacecraft domain places a strong premium on autonomy and requires dynamic recoveries and robust concurrent execution, all in the presence of tight real-time deadlines, changing goals, scarce resource constraints, and a wide variety of possible failures. To achieve this level of execution robustness, we have integrated a procedural executive based on generic procedures with a deductive model-based executive. A procedural executive provides sophisticated control constructs such as loops, parallel activity, locks, and synchronization which are used for robust schedule execution, hierarchical task decomposition, and routine configuration management. A deductive executive provides algorithms for sophisticated state inference and optimal failure recover), planning. The integrated executive enables designers to code knowledge via a combination of procedures and declarative models, yielding a rich modeling capability suitable to the challenges of real spacecraft control. The interface between the two executives ensures both that recovery sequences are smoothly merged into high-level schedule execution and that a high degree of reactivity is retained to effectively handle additional failures during recovery.

This document is based on existing documentation and tests of two existing TXT-based systems: Intel's Trusted Boot and Invisible Things Lab's Qubes OS. We describe what features are lacking in current implementations, describe what a mature system could provide, and present a list of developments to watch. Critical systems perform operation-critical computations on high importance data. In such systems, the inputs, computation steps, and outputs may be highly sensitive. Sensitive components must be protected from both unauthorized release, and unauthorized alteration: Unauthorized users should not access the sensitive input and sensitive output data, nor be able to alter them; the computation contains intermediate data with the same requirements, and executes algorithms that the unauthorized should not be able to know or alter. Due to various system requirements, such critical systems are frequently built from commercial hardware, employ commercial software, and require network access. These hardware, software, and network system components increase the risk that sensitive input data, computation, and output data may be compromised.

    Kleinman, C S

    1999-01-01

    As women have been nursing since the earliest days of recorded civilization, so nurses have been associated with health care since the earliest days of recorded medical history. Gender and function have been inextricably woven in ways that created a struggle for success within a male-dominated industry. Nurses, as women, have been undervalued as, until recently, their role in health care has been similarly undervalued. Changing realities in the health care environment have created an opportunity for women's unique skills and talents to be revalued in a way that offers new opportunities for nurses. Teamwork, global thinking, multitasking, creativity, and flexibility are characteristics that have assumed new importance in the marketplace. Nursing leaders possess these attributes, along with a strong clinical foundation that is integrated with knowledge of sound business principles. This combination now positions nurse executives to reach the highest levels of heath care administration. Critical to this achievement is the professional credibility obtained through education at the master's degree level in health care and nursing administration programs that provide the essential tools for professional success. New opportunities for nurse executives afford educators in health care and nursing administration similar opportunities to develop and market programs to this large group of health care professionals who are seeking graduate education in increasing numbers.

  4. DIALOG: An executive computer program for linking independent programs

    NASA Technical Reports Server (NTRS)

    Glatt, C. R.; Hague, D. S.; Watson, D. A.

    1973-01-01

    A very large scale computer programming procedure called the DIALOG Executive System has been developed for the Univac 1100 series computers. The executive computer program, DIALOG, controls the sequence of execution and data management function for a library of independent computer programs. Communication of common information is accomplished by DIALOG through a dynamically constructed and maintained data base of common information. The unique feature of the DIALOG Executive System is the manner in which computer programs are linked. Each program maintains its individual identity and as such is unaware of its contribution to the large scale program. This feature makes any computer program a candidate for use with the DIALOG Executive System. The installation and use of the DIALOG Executive System are described at Johnson Space Center.

  5. Executive Function in SLI: Recent Advances and Future Directions.

    PubMed

    Kapa, Leah L; Plante, Elena

    2015-09-01

    This paper provides a review of recent research on executive function abilities in children with specific language impairment (SLI). Across several studies, children with SLI are reported to perform worse than typically developing peers on measures of sustained attention, working memory, inhibition, and attention shifting. However, few studies have considered multiple executive function components simultaneously and even fewer have examined the underlying relationship between executive function deficits and impaired language acquisition. We argue that in order to fully understand the nature of executive function deficits in SLI, the field must move past simply identifying weaknesses to instead test models of executive function development and explore the nature of the relationship between executive function and language. Future research directions are recommended in order to achieve these goals.

    Computational grids provide users with many possible places to execute their applications. We wish to help users select where to run their applications by providing predictions of the execution times of applications on space shared parallel computers and predictions of when scheduling systems for such parallel computers will start applications. Our predictions are based on instance based learning techniques and simulations of scheduling algorithms. We find that our execution time prediction techniques have an average error of 37 percent of the execution times for trace data recorded from SGI Origins at NASA Ames Research Center and that this error is 67 percent lower than the error of user estimates. We also find that the error when predicting how long applications will wait in scheduling queues is 95 percent of mean queue wait times when using our execution time predictions and this is 57 percent lower than if we use user execution time estimates.

    Future NASA plans call for long-duration deep space missions with human crews. Because of light-time delay and other considerations, increased autonomy will be needed. This will necessitate integration of tools in such areas as anomaly detection, diagnosis, planning, and execution. In this paper we investigate an approach that integrates planning and execution by embedding planner-derived temporal constraints in an execution procedure. To avoid the need for propagation, we convert the temporal constraints to dispatchable form. We handle some uncertainty in the durations without it affecting the execution; larger variations may cause activities to be skipped.

    2015-01-01

    Current standardized neuropsychological tests may fail to accurately capture real-world executive deficits. We developed a computer-based Cooking Task (CT) assessment of executive functions and trialed the measure with a normative group before use with a head-injured population. Forty-six participants completed the computerized CT and subtests from standardized neuropsychological tasks, including the Tower and Sorting Tests of executive function from the Delis-Kaplan Executive Function System (D-KEFS) and the Cambridge prospective memory test (CAMPROMPT), in order to examine whether standardized executive function tasks, predicted performance on measurement indices from the CT. Findings showed that verbal comprehension, rule detection and prospective memory contributed to measures of prospective planning accuracy and strategy implementation of the CT. Results also showed that functions necessary for cooking efficacy differ as an effect of task demands (difficulty levels). Performance on rule detection, strategy implementation and flexible thinking executive function measures contributed to accuracy on the CT. These findings raise questions about the functions captured by present standardized tasks particularly at varying levels of difficulty and during dual-task performance. Our preliminary findings also indicate that CT measures can effectively distinguish between executive function and Full Scale IQ abilities. Results of the present study indicate that the CT shows promise as an ecologically valid measure of executive function for future use with a head-injured population and indexes selective executive function's captured by standardized tests.

    This report presents the implementation of a stateless scheme for Faithful Execution, the design for which is presented in a companion report, ''Principles of Faithful Execution in the Implementation of Trusted Objects'' (SAND 2003-2328). We added a simple cryptographic capability to an already simplified class loader and its associated Java Virtual Machine (JVM) to provide a byte-level implementation of Faithful Execution. The extended class loader and JVM we refer to collectively as the Sandia Faithfully Executing Java architecture (or JavaFE for short). This prototype is intended to enable exploration of more sophisticated techniques which we intend to implement in hardware.

  17. A Developmental Perspective on Executive Function

    Best, John R.; Miller, Patricia H.

    2010-01-01

    This review paper examines theoretical and methodological issues in the construction of a developmental perspective on executive function (EF) in childhood and adolescence. Unlike most reviews of EF, which focus on preschoolers, this review focuses on studies that include large age ranges. It outlines the development of the foundational components of EF—inhibition, working memory, and shifting. Cognitive and neurophysiological assessments show that although EF emerges during the first few years of life, it continues to strengthen significantly throughout childhood and adolescence. The components vary somewhat in their developmental trajectories. The paper relates the findings to longstanding issues of development (e.g., developmental sequences, trajectories, and processes) and suggests research needed for constructing a developmental framework encompassing early childhood through adolescence.

    e-Health is here to stay and experts predict that the Internet will become the hub of health care. Rapid advancements in biotechnology and medical research, increasingly curious patients who surf the Internet for medical information, and pressures from managed care companies to contain costs and speed treatments are the central components driving e-health. Despite physician reluctance to embrace the e-revolution, many hospitals and medical groups are employing the Internet and information technology to improve their customer interface, as well as to reduce business costs. This article offers seven e-strategies for health care performance improvement: (1) Supply chain management; (2) e-transactions; (3) care management; (4) improving quality; (5) boosting revenues; (6) outsourcing; and (7) provider networks (Intranets). By helping to incorporate these key e-solutions, physician executives can position their organizations for success in the new millennium.

    2015-01-01

    Individual differences in children's executive functions (EFs) are relevant for a wide range of normal and disordered psychological outcomes across the lifespan, but the origins of variation in child EFs are not well understood. We used a racially and socioeconomically diverse sample of 505 3rd-8th grade twins from the Texas Twin Project to estimate genetic and environmental influences on a common EF factor and on variance unique to four core EF domains: Inhibition, Switching, Working Memory, and Updating. As has been previously demonstrated in young adults, the common EF factor was 100% heritable, indicating that correlations among the four EF domains are entirely attributable to shared genetic etiology. Nonshared environmental influences were evident for variance unique to individual domains. General EF may thus serve as an early life marker of genetic propensity for a range of functions and pathologies later in life. PMID:26246520

  20. Executive functioning and alcohol-related aggression.

    PubMed

    Giancola, Peter R

    2004-11-01

    The primary goal of this investigation was to determine whether executive functioning (EF) would moderate the alcohol-aggression relation. Participants were 310 (152 men and 158 women) healthy social drinkers between 21 and 35 years of age. EF as well as non-EF skills were measured with 13 validated neuropsychological tests. Following the consumption of either an alcoholic or a placebo beverage, participants were tested on a modified version of the Taylor Aggression Paradigm (S. Taylor, 1967), in which mild electric shocks were received from, and administered to, a fictitious opponent. Aggressive behavior was operationalized as the shock intensities administered to the fictitious opponent. EF was negatively related to aggressive behavior for men, regardless of beverage group, even when controlling for non-EF skills. Furthermore, alcohol increased aggression only for men with lower EF scores. Finally, the mere belief that alcohol was consumed suppressed aggression for women but not for men.

    Predicting the climate change impact on biodiversity and ecosystems, advancing our knowledge of environmental phenomena interconnection, assessing the validity of simulations and other key challenges of Earth Sciences require intensive use of environmental modeling. The complexity of Earth system requires the use of more than one model (often from different disciplines) to represent complex processes. The identification of appropriate mechanisms for reuse, chaining and composition of environmental models is considered a key enabler for an effective uptake of a global Earth Observation infrastructure, currently pursued by the international geospatial research community. The Group on Earth Observation (GEO) Model Web initiative aims to increase present accessibility and interoperability of environmental models, allowing their flexible composition into complex Business Processes (BPs). A few, basic principles are at the base of the Model Web concept (Nativi, et al.): 1. Open access 2. Minimal entry-barriers 3. Service-driven approach 4. Scalability In this work we propose an architectural solution aiming to contribute to the Model Web vision. This solution applies the Brokering approach for facilitiating complex multidisciplinary interoperability. The Brokering approach is currently adopted in the new GEOSS Common Infrastructure (GCI) as was presented at the last GEO Plenary meeting in Istanbul, November 2011. According to the Brokering principles, the designed system is flexible enough to support the use of multiple BP design (visual) tools, heterogeneous Web interfaces for model execution (e.g. OGC WPS, WSDL, etc.), and different Workflow engines. We designed and prototyped a component called BP Broker that is able to: (i) read an abstract BP, (ii) "compile" the abstract BP into an executable one (eBP) - in this phase the BP Broker might also provide recommendations for incomplete BPs and parameter mismatch resolution - and (iii) finally execute the eBP using a

    An executive summary is presented of a preliminary study done on several potential High Energy Astronomy Observatory (HEAO) missions which are follow-on missions to the currently defined HEAO program. The purpose was to examine several typical missions and determine the relative complexities associated with them. The four payloads investigated were (1) a 1.2 m Diameter X-ray Telescope observatory, (2) a Large Area Moderate Angular Resolution (LAMAR) observatory, (3) a cosmic ray observatory, and (4) a gamma ray observatory. Each of the four observatories was considered a national facility. Low cost approaches were stressed throughout, with considerable use of HEAO Block I experience and designs effected to provide a high degree of confidence that such approaches were achievable. The use of the Multi-Mission Spacecraft (MMS) and the HEAO Block I spacecraft was considered as a result of this low cost emphasis. Also, NASA standard components were considered, where applicable.

    The field of high-performance computing (HPC) has provided a wide array of strategies for supplying additional computing power to the goal of reducing the total "clock time" required to complete various computational processes. These strategies range from the development of higher-performance hardware to the assembly of large networks of commodity computers, with each strategy designed to address a particular aspect and/or manifestation of a given computational problem. GWE (Grid Wizard Enterprise) in that regard, is an HPC distributed enterprise system, aimed at providing a solution to the particular problem of running inter-independent computational processes faster by parallelizing their execution across a virtual grid of computational resources with a minimum of user intervention.

    Beyond the recent accounting scandals, something is wrong with the way most companies are managed today. That's the message of this fictional letter from a board member to a CEO, written by Joseph Fuller, CEO of strategy consulting firm the Monitor Group. The letter highlights the challenges and complexities of running a business in today's uncertain environment. And while it avoids the facile bashing of U.S. executives so common these days, the missive nonetheless casts a harsh light on the flaws that have recently been exposed in the American management model. The letter addresses a single CEO and company, yet it is intended to speak to executives and boards everywhere: "It wasn't the recession that caused us to make three acquisitions in two years at very, very high prices; the need to fuel [unreasonable] growth did. Nor was it the recession that caused us to expand our capacity in anticipation of gaining market share; rather, it was our own overly optimistic sales forecasts that led us to that decision. Where did those forecasts originate? From line managers trying to fulfill profit goals that we created after meeting with the analysts. "The root cause of many of the problems that became apparent in the last 24 months lies not with the economy, not with September 11, and not with the dot-com bubble. Rather, it lies with that willingness to be led by outside forces-indeed, our own lack of conviction about setting a course." Restoring sound, strategic decision making--thinking that looks beyond tomorrow's analyst reports--will go a long way toward keeping those outside forces at bay, according to Fuller.

  6. Building the blocks of executive functioning: differentiating early developing processes contributing to executive functioning skills.

    2011-12-01

    The neural processes that underlie executive function begin to develop in infancy. However, it is unclear how the behavior manifested by these processes are related or if they can be differentiated early in development. This study seeks to examine early emerging executive functioning skills in monkeys (Macaca fascicularis) by using an error analysis approach where traditional measures of the tasks, as well as identification of major error patterns are related. Results show that during the infancy and early juvenile period, two processes that help support set-maintenance could be differentiated: modulation of responses to novelty and persistence despite negative feedback. The results suggest that these two aspects of set-maintenance were largely independent. Modulation of responses to novelty was most prominent in the infancy and early juvenile period. The ability to persist with a response set despite negative feedback emerged in the early juvenile period and was related to task performance until the end of the study.

  7. The execution trap. Drawing a line between strategy and execution almost guarantees failure.

    PubMed

    Martin, Roger L

    2010-01-01

    The realization of a strategy depends on countless employees. So it's no surprise that when a strategy fails, the reason cited is usually poor execution. But this view of strategy and execution relies on a false metaphor in which senior management is a choosing brain while those in the rest of the company are choiceless arms and legs that merely carry out the brain's bidding. The approach does damage to the corporation because it alienates the people working for it. A better metaphor for strategy is a white-water river, in which choices cascade from its source in the mountains (the corporation) to its mouth (the rest of the organization). Executives at the top make the broader choices involving long-term investments while empowering employees toward the bottom to make more concrete, day-to-day decisions that directly influence customer service and satisfaction. For the cascade to flow properly, a choice maker upstream can set the context for those downstream by doing four things: explaining what the choice is and why it's been made, clearly identifying the next downstream choice, offering help with making choices as needed, and committing to revisit and adjust the choice based on feedback. When downstream choices are valued and feedback is encouraged, employees send information upward, improving the knowledge base of decision makers higher up and helping everyone in the organization make better choices.

  2. LQCD workflow execution framework: Models, provenance and fault-tolerance

    Piccoli, Luciano; Dubey, Abhishek; Simone, James N.; Kowalkowlski, James B.

    2010-04-01

    Large computing clusters used for scientific processing suffer from systemic failures when operated over long continuous periods for executing workflows. Diagnosing job problems and faults leading to eventual failures in this complex environment is difficult, specifically when the success of an entire workflow might be affected by a single job failure. In this paper, we introduce a model-based, hierarchical, reliable execution framework that encompass workflow specification, data provenance, execution tracking and online monitoring of each workflow task, also referred to as participants. The sequence of participants is described in an abstract parameterized view, which is translated into a concrete data dependency based sequence of participants with defined arguments. As participants belonging to a workflow are mapped onto machines and executed, periodic and on-demand monitoring of vital health parameters on allocated nodes is enabled according to pre-specified rules. These rules specify conditions that must be true pre-execution, during execution and post-execution. Monitoring information for each participant is propagated upwards through the reflex and healing architecture, which consists of a hierarchical network of decentralized fault management entities, called reflex engines. They are instantiated as state machines or timed automatons that change state and initiate reflexive mitigation action(s) upon occurrence of certain faults. We describe how this cluster reliability framework is combined with the workflow execution framework using formal rules and actions specified within a structure of first order predicate logic that enables a dynamic management design that reduces manual administrative workload, and increases cluster-productivity.

  13. Temperament, Executive Control, and ADHD across Early Development

    Rabinovitz, Beth B.; O’Neill, Sarah; Rajendran, Khushmand; Halperin, Jeffrey M.

    2015-01-01

    Research examining factors linking early temperament and later ADHD is limited by cross-sectional approaches and having the same informant rate both temperament and psychopathology. We used multi-informant/multi-method longitudinal data to test the hypothesis that negative emotionality during preschool is positively associated with ADHD symptom severity in middle childhood, but developing executive control mediates this relation. Children (N=161) with and without ADHD were evaluated three times: Parent and teacher temperament ratings and NEPSY Visual Attention at ages 3–4 years; WISC-IV Working Memory Index and NEPSY Response Set at age 6 years; and ADHD symptoms using the Kiddie-SADS at age 7 years. Parent and teacher ratings of preschoolers’ temperament were combined to form an Anger/Frustration composite. Similarly, an Executive Functioning composite was derived from age 6 measures. Bootstrapping was used to determine whether age 6 Executive Functioning mediated the relation between early Anger/Frustration and later ADHD symptom severity, while controlling for early executive functioning. Preschoolers’ Anger/Frustration was significantly associated with later ADHD symptoms, with this relation partially mediated by age 6 Executive Functioning. Developing executive control mediates the relation between early Anger/Frustration and later ADHD symptom severity, suggesting that Anger/Frustration influences ADHD symptom severity through its impact on developing executive control. Early interventions targeting the harmful influences of negative emotionality or enhancing executive functioning may diminish later ADHD severity. PMID:26854505

  8. Modelling Limit Order Execution Times from Market Data

    NASA Astrophysics Data System (ADS)

    Kim, Adlar; Farmer, Doyne; Lo, Andrew

    2007-03-01

    Although the term ``liquidity'' is widely used in finance literatures, its meaning is very loosely defined and there is no quantitative measure for it. Generally, ``liquidity'' means an ability to quickly trade stocks without causing a significant impact on the stock price. From this definition, we identified two facets of liquidity -- 1.execution time of limit orders, and 2.price impact of market orders. The limit order is an order to transact a prespecified number of shares at a prespecified price, which will not cause an immediate execution. On the other hand, the market order is an order to transact a prespecified number of shares at a market price, which will cause an immediate execution, but are subject to price impact. Therefore, when the stock is liquid, market participants will experience quick limit order executions and small market order impacts. As a first step to understand market liquidity, we studied the facet of liquidity related to limit order executions -- execution times. In this talk, we propose a novel approach of modeling limit order execution times and show how they are affected by size and price of orders. We used q-Weibull distribution, which is a generalized form of Weibull distribution that can control the fatness of tail to model limit order execution times.

  9. The roles of associative and executive processes in creative cognition.

    PubMed

    Beaty, Roger E; Silvia, Paul J; Nusbaum, Emily C; Jauk, Emanuel; Benedek, Mathias

    2014-10-01

    How does the mind produce creative ideas? Past research has pointed to important roles of both executive and associative processes in creative cognition. But such work has largely focused on the influence of one ability or the other-executive or associative-so the extent to which both abilities may jointly affect creative thought remains unclear. Using multivariate structural equation modeling, we conducted two studies to determine the relative influences of executive and associative processes in domain-general creative cognition (i.e., divergent thinking). Participants completed a series of verbal fluency tasks, and their responses were analyzed by means of latent semantic analysis (LSA) and scored for semantic distance as a measure of associative ability. Participants also completed several measures of executive function-including broad retrieval ability (Gr) and fluid intelligence (Gf). Across both studies, we found substantial effects of both associative and executive abilities: As the average semantic distance between verbal fluency responses and cues increased, so did the creative quality of divergent-thinking responses (Study 1 and Study 2). Moreover, the creative quality of divergent-thinking responses was predicted by the executive variables-Gr (Study 1) and Gf (Study 2). Importantly, the effects of semantic distance and the executive function variables remained robust in the same structural equation model predicting divergent thinking, suggesting unique contributions of both constructs. The present research extends recent applications of LSA in creativity research and provides support for the notion that both associative and executive processes underlie the production of novel ideas.
