subject: FOS: Physical sciences

description: We investigate theoretically shot noise in an artificial Single Molecule Magnet based upon a CdTe quantum dot doped with a single S=5/2 Mn spin and gated in the hole sector. Mn-hole exchange anisotropy is shown to lead to profound consequences on noise, like super-Poissonian behaviour. We report on a novel effect, similar to the Dicke effect in Quantum Optics, that allows to separately extract the hole and Mn spin relaxation times using frequency-resolved shot noise measurements. We expect that our findings may have further relevance to experiments in other S>1/2 systems including transport through Mn(12) molecules and STM spectroscopy of magnetic atoms.

description: We study the Fock description of a quantum free field on the three-sphere with a mass that depends explicitly on time, also interpretable as an explicitly time dependent quadratic potential. We show that, under quite mild restrictions on the time dependence of the mass, the specific Fock representation of the canonical commutation relations which is naturally associated with a massless free field provides a unitary dynamics even when the time varying mass is present. Moreover, we demonstrate that this Fock representation is the only acceptable one, up to unitary equivalence, if the vacuum has to be SO(4)-invariant (i.e., invariant under the symmetries of the field equation) and the dynamics is required to be unitary. In particular, the analysis and uniqueness of the quantization can be applied to the treatment of cosmological perturbations around Friedmann-Robertson-Walker spacetimes with the spatial topology of the three-sphere, like e.g. for gravitational waves (tensor perturbations). In addition, we analyze the extension of our results to free fields with a time dependent mass defined on other compact spatial manifolds. We prove the uniqueness of the Fock representation in the case of a two-sphere as well, and discuss the case of a three-torus.

Kinematic Positioning with DGPS: Expanding Frontiers in Aerogeophysics
Creators: name: Bell, Robin E.
Publisher: name: Columbia University
Year: 1997
Subjects: Geographic information systems

description: Airborne geophysics has long been used for regional studies of remote and inaccessible areas. Recent developments in precise positioning of aircraft with the Global Positioning System (GPS) have greatly expanded the range of previously intractable science problems which now can be addressed with airborne techniques (i.e. Brozena et al, 1992). Differential GPS techniques for modern aerogeophysical studies include both realtime navigation of the aircraft and post-mission recovery of the precise positions for data reduction. Major science problems which have been addressed recently with aerogeophysics include deciphering the dynamics of the world's major ice sheets, imaging surface displacements due to earthquakes and decoding the structure of the continental lithosphere. Airborne studies often recover higher resolution data than can be retrieved with satellite technology. Subsequently the aircraft based approach fills a unique niche where land and ship based operations are expensive, difficult or even impossible.
Perceptions and experiences of languages education in regional Victoria: Identity, culture and place
Creators: name: LUBITZ, KARIN ILSE
Publisher: name: Monash University
Year: 2021
Subjects: Language

description: This qualitative narrative research sought to identify the perceptions and experiences regarding the learning of languages other than English of families and former language teachers in a regional Victorian community. Data was interpreted by drawing on concepts such as identity, place and rurality. Viewed through the lens of critical sociology, we come to understand what the participants value as individuals and as a community. In order to enhance the provision of languages education in regional communities, it has to be perceived as culturally relevant in a local as well as in a global sense.
title: Non-Contingent Reinforcement in a Counseling Like Situation
Creators: name: Shelton, Robert B.
Publisher: name: Utah State University
Year: 1973

description: The purpose of this study was to determine if a variable, non-contingent reinforcement, could account for a significant amount of the effect of psychotherapy. A sample of ninety subjects was drawn from basic psychology classes and randomly assigned to six groups in a variation of the Soloman 4-group design. The treatment groups were connected to sham GSR equipment and told that when a light flashed the y had made an anxiety reducing statement and were becoming more mentally healthy. The subjects were given three by five cards upon which were typed positive-negative adjective pairs and told to use the cards as cues to talk about themselves. The subjects were placed on a variable interval schedule with a mean of 10 seconds. No significant difference was found for the treatment.
Tree diameter, height and stocking in even-aged forests

Subjects: subject: Quantitative Methods (q-bio.QM)

description: Empirical observations suggest that in pure even-aged forests, the mean diameter of forest trees (D, diameter at breast height, 1.3 m above ground) tends to remain a constant proportion of stand height (H, average height of the largest trees in a stand) divided by the logarithm of stand density (N, number of trees per hectare): D = beta (H-1.3)/Ln(N). Thinning causes a relatively small and temporary change in the slope beta, the magnitude and duration of which depends on the nature of the thinning. This relationship may provide a robust predictor of growth in situations where scarce data and resources preclude more sophisticated modelling approaches.

title: Expressed Group Member Satisfaction and Measured Group Difference Between Trained and Untrained Group Members
Creators: name: Kilstrom, Dennis Randall
Publisher: name: Utah State University
Year: 1972

description: In college programs utilizing the quarter system there arise problems in the development of encounter groups due to a limited amount of time available. A short training program in evaluating group processes might be one way to facilitate group development. In order to test one such program two hypotheses were generated. Hypotheses I was tested for a significant difference between a Treatment Group, receiving training, and a Control Group, receiving no training, in expressed member satisfaction. Hypothesis II was tested for a significant difference in the therapeutic value of rated interaction between the Treatment and Control Group. Expressed member satisfaction was measured by a Group Rating Scale . Therapeutic value of interaction was measured by the Hill Interaction Matrix.
Two groups of eight subjects were used. Each group had the same leader and met for eight, two and one-half hour sessions, and a three hour training period.
The Treatment Group and the Control Group were exposed to three hours of training with the experimenter. The Treatment Group received three hours of training on the Hill Interaction Matrix. The Control Group received three hours of "placebo'' training consisting of an explanation of the purpose of feedback. The dependent variables then were "feedback" for the Control Group and HIM training for the Treatment Group.
The results of the study were favorable to the Treatment Group. Significant differences were revealed on five of the 16 items of the Group Rating Scale. Similarly the Treatment Group received a significantly higher rating in therapeutic value in Quadrant III of the Hill Interaction Matrix after receiving training. However, due to several confounding variables it cannot be definitely stated the results were due to the effects of treatment.

description: Hydrodynamical models have generally failed to describe interferometry radii measured at RHIC. In order to investigate this ``HBT puzzle'', we carry out a systematic study of HBT radii in ultrarelativistic heavy-ion collisions within a two-dimensional transport model. We compute the transverse radii $R_o$ and $R_s$ as functions of $p_t$ for various values of the Knudsen number, which measures the degree of thermalization in the system. For realistic values of the Knudsen number estimated from $v_2$ data, we obtain $R_o/R_s \simeq 1.2$, much closer to data than standard hydrodynamical results. Femtoscopic observables vary little with the degree of thermalization. Azimuthal oscillations of the radii in non central collisions do not provide a good probe of thermalization.

description: Laue lenses are an emerging technology based on diffraction in crystals that allows the concentration of soft gamma rays. This kind of optics that works in the 100 keV - 1.5 MeV band can be used to realize an high-sensitivity and high-angular resolution telescope (in a narrow field of view). This paper reviews the recent progresses that have been done in the development of efficient crystals, in the design study and in the modelisation of the answer of Laue lenses. Through the example of a new concept of 20 m focal length lens focusing in the 100 keV - 600 keV band, the performance of a telescope based on a Laue lens is presented. This lens uses the most efficient mosaic crystals in each sub-energy range in order to yield the maximum reflectivity. Imaging capabilities are investigated and shows promising results.

description: The first paleomagnetic data from Permian and Triassic formations west of the Andean divide are presented. Four formations of Permian or Triassic age in the central Chilean Andes have been investigated: two are located in the coastal ranges, and two are in the main cordillera. Of the formations in the main cordillera (Pastos Blancos and Matahuaico formations), only the Pastos Blancos Formation has yielded characteristic directions. While a fold test is absent, magnetizations are most likely secondary and yield pre-tilt corrected concordant inclinations, but yield declinations discordant 30° clockwise in comparison to the South American apparent polar wander path. Both formations from the coastal ranges (Cifuncho and Pichidangui formations) yielded stable directions. Postfolding magnetizations in the Cifuncho Formation also show declinations discordant 30° clockwise and concordant inclinations. The Pichidangui Formation has two stable components: one of postfolding age is concordant to apparent polar wander path data, and one of probable prefolding (Late Triassic) age is concordant in declination, but discordant in inclination. Further work is needed to better define the prefolding magnetizations in the Pichidangui Formation, but at present these preliminary results are the first paleomagnetic signs of displaced terranes along the Pacific margin of Chile. If correct, the results suggest that the Pichidangui Formation was some 15° of latitude farther south during the Late Triassic and had likely moved northward to its present latitudinal position with respect to cratonic South America by Middle to Late Jurassic.

description: Structured files used with database management systems are at the forefront of sophisticated analytic tools for data mining. The use of a flexible file address space beneath these structured files can achieve high performance read and writes. However, because FlexFile allows in-place updates to arbitrary-sized data, a new caching system must be realized which leverages this uniquely shifting logical address space. In this paper, we present the cache structures block caching and replacement policy as well as the process to integrate the cache to the Linux kernel via a modularized driver. To validate our methodologies, we measure our cache against the Linux Page Cache. Testing results show that certain cases where utilizing a logical cache can achieve better results over the Linux Page Cache.

Improved method of determining the component separation of blended spectral lines.
Creators: name: Olson, Bernt Ingemar
Publisher: name: University of British Columbia
Year: 2011

description: An automated method of determining the relative line separations on digitized blended stellar spectra has been developed. A pair of standard profiles are fitted to the observed blended profile by allowing the standards to relax in position and amplitude until a least-square 'best fit' is obtained. The technique has been tested on numerous blends of known separation and it has been shown that with certain restrictions on the relative amplitudes it is not susceptible to systematic errors. Blended hydrogen and helium lines in two B-stars have been separated to < 100 km/sec at 30 A/mm with a probable error of 15 km/sec.
Implications of astronomical climate cycles to the chronology of the Triassic

description: A high resolution climate record from a thick, continuous sedimentary sequence in the Newark basin provides the basis for an astronomically calibrated time scale for the Late Triassic. The astronomical vernier, indexed to radiometric dates that indicate an age of 202 Ma for the Triassic/Jurassic boundary, suggests that the Late Triassic was about 31 m.y. long, or constituted about 2/3 of the entire Triassic. A detailed geomagnetic polarity time scale developed in conjunction with the cycle stratigraphy provides a mechanism to extend the astronomical chronology to other sections in the world.
title: A Correlation Study between the Shipley-Hartford Test of Mental Maturity and the Minnesota Multiphasic Personality Inventory
Creators: name: Speechly, Richard Roy
Publisher: name: Utah State University
Year: 1973

description: The Minnesota Multiphasic Personality Inventory (MMPI) has been v recognized as a helpful tool to the psychologist in identifying abnormal characteristics (Leverenz, 1956; Modlin, 1956; Hathaway and Mckinley, 1967; Hock, 1970). Likewise the Shipley-Institute of Living Scale for Measuring Intellectual Impairment (S-H) has also been recognized as a helpful tool in identifying emotional impairment (Pollack, 1942; Halstead, 1943; Fleming, 1943; Wright, 1946; Garfield and Fey, 1948; Lewinsohn, 1963) . Despite the research which suggests both tests are capable of helpful diagnosis in the general area of psychological impairment (Welch, 1956; Lewinsohn, 1963), little if any work has been done examining the compatibility of the two instruments. Therefore, a correlation study was made between the two tests.
Sixty-one male in-patients of the Wyoming State Hospital, between the ages of 18-45 (Garfield and Fey, 1948) and having a verbal IQ of 14. 3 years (Shipley and Burlingame, 1941), were administered both the S-H and the MMPI. The conceptual quotient (CQ), "a measure of intellectual impairment based upon the assumption that where there is intellectual impairment, vocabulary is less affected than is the capacity for abstract thinking and that in such cases there will be a discrepancy between vocabulary level and the ability to handle abstract problems" (Lewinsohn, 1963, p. 444) of the S-H, was correlated with the number of Peterson's Psychotic Profile Signs (Peterson, 1954) a patient might acquire after taking the MMPI. Peterson's model was chosen as the criteria for discriminating MMPI profiles because of its relative case of use and successful experimental value (Peterson, 1954). Secondly, the CQ score was correlated with each individual subtest "T" score of the MMPI. Analysis of the experimental data was achieved statistically by use of Pearson's product-moment correlation.
The results of the study showed no significant correlation between S-H's CQ and Peterson's signs. Further, no significant correlation was found with eight of the ten subtest scores on the MMPI and Shipley's CQ. However, there was a low but significant correlation between Shipley's CQ and the Hy and Mf subscales of the MMPI. No determining factor was found to explain the common variance in these two correlations.

description: Revised palaeogeographic reconstructions of the Atlantic-bordering continents and intervening terranes are presented for the Siluro-Devonian boundary, Early Devonian, and Late Devonian, based on incorporation of new palaeomagnetic results that have become available from Laurentia and Gondwana. The key features of the palaeogeographic model are the transpressive collision between the eastern margin of Laurentia and the northwest South American margin of Gondwana in the Siluro-Devonian, and the subsequent Devonian retreat of the north African margin and the development of a wide ocean between Africa and Europe by the Late Devonian. Although rather complex and involving rapid motions especially of Gondwana, the revised Devonian plate tectonic evolution as indicated by palaeomagnetism is not inconsistent with biogeographic and palaeoclimatological evidence.

(1968) published their time-scale that the relative widths of the magnetic polarity intervals for this entire interval have been systematically determined from magnetic profiles.
Kinetic, spectroscopic and potentiometric studies of the redox reactions of the iron (III) and copper (II) thiosulfate complexes
Creators: name: Beach, Fiona G.
Publisher: name: University Of Tasmania
Year: 2023

description: The mechanism of the copper(II)-catalysed oxidation of thiosulfate ion by iron(III) in aqueous solutions is poorly understood, but is of interest because of its analytical applications, and its relevance to the disposal of waste solutions of thiosulfate and sulfoxyanions in general. The aim of this study was to determine or confirm the mechanisms of the reactions between copper(H) and thiosulfate, iron(III) and thiosulfate, and the reaction of aqueous mixtures of both metal ions with thiosulfate. This was done with a view to assessing the application of these reactions in both existing and proposed analytical procedures for the determination of copper and/or iron in aqueous media, with techniques such as flow-injection analysis. Stopped-flow and continuous flow methods were employed both to characterise the short-lived, coloured complexes of copper(II) and iron(III) with thiosulfate and to record kinetic data for the study of their rapid decomposition reactions. In addition, Raman spectra of frozen solutions of the iron (III)-thiosulfate complex were recorded for the first time.

description: Early Mesozoic tholeiitic flood basalts of the Central Atlantic Magmatic Province (CAMP) are interbedded throughout much of their extent with cyclical lacustrine strata, allowing Milankovitch calibration of the duration of the extrusive episode. This cyclostratigraphy extends from the Newark basin of the northeastern US, where it was first worked out, to Nova Scotia and Morocco and constrains the outcropping extrusive event to less than 600 ky in duration, beginning roughly 20 ky after the Triassic-Jurassic boundary, and to within one pollen and spore zone and one vertebrate biochron. Based principally on the well-known Newark astronomically calibrated magnetic polarity time scale with new additions from the Hartford basin, the rather large scatter in recent radiometric dates from across CAMP (>10 m.y.), centering on about ~200 m.y., is not likely to be real. Rather, the existing paleomagnetic data from both intrusive and extrusive rocks suggest emplacement of nearly all the CAMP within less than 3 m.y. of nearly entirely normal polarity. The very few examples of reversed magnetizations suggest that some CAMP activity probably occurred just prior to the Triassic-Jurassic boundary. Published paleomagnetic and 40Ar / 39Ar data from the Clubhouse Crossroads Basalt are reviewed and with new paleomagnetic data suggest that alteration and possible core misorientation could be responsible for the apparent differences with the CAMP. The Clubhouse Crossroads Basalt at the base of the Coastal Plain of South Carolina and Georgia provides a link to the volumetrically massive volcanic wedge of seaward dipping reflectors present in the subsurface off the southeastern US that may be part of the same igneous event, suggesting that the CAMP marks the formation of the oldest Atlantic oceanic crust.

description: We investigate whether the recently proposed PT-symmetric extensions of generalized Korteweg-de Vries equations admit genuine soliton solutions besides compacton solitary waves. For models which admit stable compactons having a width which is independent of their amplitude and those which possess unstable compacton solutions the Painleve test fails, such that no soliton solutions can be found. The Painleve test is passed for models allowing for compacton solutions whose width is determined by their amplitude. Consequently these models admit soliton solutions in addition to compactons and are integrable.

Publisher: name: Utah State University
Year: 1973

description: The present study investigated the effects of progressive relaxation training using an abridged form of Jacobson's (1938) relaxation exercises on the mean number of nocturnal sleep disturbances in a group of psychiatric inpatients. Nocturnal time-sampling observations were made during a 14 day base line to select Ss who averaged 1.5 sleep disturbances per night. Six women, ranging in age from 23 to 56 years, were classified as problem sleepers and were moved to a common bedroom, where a second 16 day base line was taken to control for changes in the nocturnal environment. After a brief introduction and demonstration, a tape recording of the relaxation exercises was played each night of the 20 day experimental period. Results indicate a statistically significant decrease (p < .05) in the mean number of sleep disturbances as compared to base line levels. Caution was suggested in interpreting the results due to the possibility of interaction between the performance of the relaxation exercises, alteration of the nocturnal environment, and Ss' hypnotic drug medication.

description: We evaluated the age of two Upper Eocene impact ejecta layers (North American microtektites linked to the Chesapeake Bay impact structure and clinopyroxene [cpx] spherules from the Popigai crater) and the global effects of the associated impact events. The reported occurrence of cpx spherules from the Popigai impact structure at South Atlantic ODP Site 1090 within the middle of magnetochron C16n.1n yields a magnetochronologic age of 35.4 Ma. We generated high-resolution stable isotope records at Sites 1090, 612 (New Jersey slope), and Caribbean core RC9-58 that show: (1) a 0.5‰ δ^13C decrease in bulk-carbonate at Site 1090 coincident with the Popigai cpx spherule layer, and (2) a 0.4‰-0.5‰ decrease in deep-water benthic foraminiferal δ^13C values across the Popigai impact ejecta layer at Site 612 and core RC9-58. We conclude that the δ^13C excursion associated with Popigai was a global event throughout the marine realm that can be correlated to magnetochron C16n.1n. The amplitude of this excursion (~0.5‰) is within the limits of natural variability, suggesting it was caused by a decrease in carbon export productivity, potentially triggered by the impact event(s). North American microtektites associated with the Chesapeake Bay impact occur stratigraphically above the Popigai cpx spherules at Site 612 and core RC9-58. We found no definite evidence of a δ^13C anomaly associated with the North American microtektite layer, though further studies are warranted. High-resolution bulk-carbonate and benthic foraminiferal δ^18O records show no global temperature change associated with the cpx spherule or North American microtektite layers.

description: The Boston University-Five College Radio Astronomy Observatory (BU-FCRAO) Galactic Ring Survey (GRS) of 13 CO (1-0) emission covers Galactic longitudes 18 deg < l < 55.7 deg and Galactic latitudes |b| <= 1 deg. Using the SEQUOIA array on the FCRAO 14m telescope, the GRS fully sampled the 13 CO Galactic emission (46 arcsec angular resolution on a 22 arcsec grid) and achieved a spectral resolution of 0.21 km/s. Because the GRS uses 13 CO, an optically thin tracer, rather than 12 CO, an optically thick tracer, the GRS allows a much better determination of column density and also a cleaner separation of velocity components along a line of sight. With this homogeneous, fully-sampled survey of 13 CO, emission, we have identified 829 molecular clouds and 6124 clumps throughout the inner Galaxy using the CLUMPFIND algorithm. Here we present details of the catalog and a preliminary analysis of the properties of the molecular clouds and their clumps. Moreover, we compare clouds inside and outside of the 5 kpc ring and find that clouds within the ring typically have warmer temperatures, higher column densities, larger areas, and more clumps compared to clouds located outside the ring. This is expected if these clouds are actively forming stars. This catalog provides a useful tool for the study of molecular clouds and their embedded young stellar objects.

Mobility of Pangea: Implications for Late Paleozoic and Early Mesozoic paleoclimate

description: Several recent analyses of paleomagnetic data support the concept of Pangea, an assemblage of most of the world‘s continents that was mobile in terms of large-scale internal deformation and with respect to paleolatitude. The main feature of internal deformation involved the transformation from a Pangea B—type configuration in the late Paleozoic, with northwestern South America adjacent to eastern North America, to a more traditional Pangea A—type configuration in the early Mesozoic, with northwestern Africa adjacent to eastern North America. Pangea B thus seems to coincide in time with extensive low-latitude coal deposition and high southern-latitude Gondwana glaciations, whereas Pangea A coincides with generally drier conditions over the continents and no polar ice sheets. Although the configuration of Pangea may have been more stable as an A-type configuration in the Early and Middle Jurassic prior to breakup, the paleomagnetic evidence suggests that there was appreciable latitudinal change of the assembly. Such changing tectonic boundary conditions emphasize the practical importance of age registry of paleoclimate data in making valid comparisons with model results. A simple zonal climate model coupled with the geocentric axial dipole hypothesis for establishing paleolatitudes in precisely controlled paleogeographic reconstructions can explain many of the climate patterns in both the late Paleozoic and the early Mesozoic, but it cannot explain the presence or absence of continental ice sheets.

description: We calculate Keplerian (mass shedding) configurations of rigidly rotating neutron stars and quark stars with crusts. We check the validity of empirical formula for Keplerian frequency, f_K, proposed by Lattimer & Prakash, f_K(M)=C (M/M_sun)^1/2 (R/10km)^-3/2, where M is the (gravitational) mass of Keplerian configuration, R is the (circumferential) radius of the non-rotating configuration of the same gravitational mass, and C = 1.04 kHz. Numerical calculations are performed using precise 2-D codes based on the multi-domain spectral methods. We use a representative set of equations of state (EOSs) of neutron stars and quark stars. We show that the empirical formula for f_K(M) holds within a few percent for neutron stars with realistic EOSs, provided 0.5 M_sun < M < 0.9 M_max,stat, where M_max,stat is the maximum allowable mass of non-rotating neutron stars for an EOS, and C=C_NS=1.08 kHz. Similar precision is obtained for quark stars with 0.5 M_sun < M < 0.9 M_max,stat. For maximal crust masses we obtain C_QS = 1.15 kHz, and the value of C_QS is not very sensitive to the crust mass. All our C's are significantly larger than the analytic value from the relativistic Roche model, C_Roche = 1.00 kHz. For 0.5 M_sun < M < 0.9 M_max,stat, the equatorial radius of Keplerian configuration of mass M, R_K(M), is, to a very good approximation, proportional to the radius of the non-rotating star of the same mass, R_K(M) = aR(M), with a_NS \approx a_QS \approx 1.44. The value of a_QS is very weakly dependent on the mass of the crust of the quark star. Both a's are smaller than the analytic value a_Roche = 1.5 from the relativistic Roche model.

Publisher: name: University of British Columbia
Year: 2011

description: A statistical study of the orbital elements of Spectroscopic Binary Systems is undertaken with attention given to the distribution of ω, the longitude of periastron, and the observed distribution of orbital eccentricities and periods. Selection effects are taken into account in both cases. Test results indicate that the major non-uniformities previously found by other investigators for the distribution of u have been reduced or eliminated for certain categories of data. A positive correlation is discovered for the observed tabulation of periods and eccentricities. The latter result is viewed with caution, due to certain criteria established in the analysis.

description: The profession of counseling psychology has, for a long time, realized the need for reevaluating and improving traditional methods of training counselors. The major professional demands have been (1) a science-based approach to the training counselors; and (2) a more experientially oriented approach to the training of counselors. This study represented a developmental effort geared towards the integration of the above two demands.
Seven experientially oriented modular instructional units were developed for use in a counselor education program. Units were developed on (1) what counseling and psychotherapy are; (2) history of counseling and psychotherapy; (3) counselor attitudes; (4) interviewing skills (A); (5) interviewing skills (B); (6) critical incidents in counseling and psychotherapy; and (7) counselor values, and ethical and legal responsibilities in counseling and psychotherapy.
The Instructional units adopted a format containing (1) specific learning objectives; (2) descriptions of learning activities; and (3) evidence of learning or criteria statements for each learning objective. The seven units were put into training manual form. An instructor's manual was also developed to enable any counselor educator to teach the course by familiarizing himself with the manuals.
The modular instructional systems were field tested on a pilot group of nine graduate students in counseling psychology. The pilot group met for six hours of class time each week for ten consecutive weeks. As a result of the field testing, parts of the system were either modified, eliminated, or added.
The study concluded that the systems approach to counselor education is a viable alternative to more traditional methods of counselor education. It is a science-based approach characterized by a high level of accountability, and it offers and efficient and effective method for counselor education.

description: Researchers often want to share their datasets, complex analyses, or tools with others. However, if collaborators or decision makers lack coding expertise, this can be a significant barrier to engagement. Shiny is a package and framework for R users to create interactive online applications, without the need for web development skills. In this presentation, I will introduce the basic architecture of a Shiny application, highlight use-cases via example applications, and provide some tips for getting started.

description: Late Proterozoic and Palaeozoic (pre-Permian) palaeomagnetic data from all regions involved in, or adjacent to, the Caledonian-Appalachian orogenic belt are reviewed. Between about 1100 and about 800 Ma the Laurentian and Baltic shields were close together, prior to the opening phase of the Caledonian-Appalachian Wilson cycle. The problems of tectonic interpretation of Palaeozoic palaeomagnetic data from within and around the belt derive mostly from differences of typically 10°-20° between the pole positions. These can variously be interpreted in terms of (i) relative displacements between different continents or terranes, (ii) differences in ages of remanence and (iii) aberrations due to inadequacy of data or geomagnetic complexity, and it is not always easy to discriminate between these alternatives. If the Pangaea A2 reassembly of continents around the northern and central Atlantic is taken as the end-product of Caledonian-Appalachian orogenesis, the following conclusions can be drawn: 1. Lower Palaeozoic palaeolatitude differences between the N American and British-Scandinavian margins of the Caledonides are small; hence any convergence must have been mainly E-W. 2. There are additional differences which could be due to major pre-Carboniferous strike-slip (more than 1000 km), although later strike-slip on this scale is no longer considered likely. 3. The Lower Palaeozoic apparent polar wander paths for Northern Scotland and N America disagree on face value, but must be reconciled if their conventionally assumed geographic relation is correct. 4. Lower Old Red Sandstone data from Britain and Norway disagree, but this is more likely to be due to magnetic overprinting in the Norwegian rocks than to remnant oceans between the regions of Old Red Sandstone facies. 5. Armorica seems to have been far to the S, adjacent to Gondwana, in Ordovician time. The latest view is that it collided with Euramerica in early Devonian time to form the Old Red Continent. 6. The timing of Gondwana's collision with the Old Red Continent is controversial; it is within either the late Devonian or the Carboniferous. If it occurred early in that time range, much of Hercynian-Alleghanian orogeny post-dated it.

description: The occurrence of “initial cracking” in bridges during proof load testing (PLT) is a relatively brief procedure, taking only a few hours. Its long-term effects may play a role in future understanding of the future behavior of the bridge. In this paper, we document a brief period of PLT via interrogation an FBG sensor (central wavelength of 1554.2nm) in an arch spandrel bridge which was constructed before opening for public use. We logged data before, during and after the load testing session using a broadband light source and a tunable laser. Based on the data, we discuss the wavelength shift profiles, and its morphology during the period. The main findings of this study reveals that the initial cracking procedure exhibits unique behavior indicated by the sudden changes of the FBG spectra, though exhibiting some latency. Prior to the PLT session (acclimatizing window), there were already perturbations to structure causing up to 0.2nm shift in the FBG central wavelength, while during the PLT session, the central wavelength snapped between ~1554.1nm to ~1554.3nm. The fluctuations stopped after the PLT, confirmed with tunable lasers’ profile as well. These findings demonstrates that not only initial crackings most likely can be detected via PLT, but it may also occur before the PLT exercise itself due to its own intrinsic load.

description: New information has become available that requires a revision of Paleogene chronology incorporated in most current Cenozoic time scales. Age estimates for the limits of the Paleogene (the Oligocene/Miocene and Cretaceous/Paleogene boundaries) have not changed appreciably and remain at about 24 Ma and about 66 Ma, respectively. However, new radioisotope data indicate that boundaries of subdivisions within the Paleogene are generally younger than previously estimated, for example, the Paleocene/Eocene and Eocene/Oligocene, by about 2 to 3 m.y. We review the current status of magnetobiostratigraphic correlations and new radioisotope data, with particular reference to late Eocene~early Oligocene geochronology and provide a reassessment of the age of the Eocene/Oligocene boundary as 34 Ma. We anticipate that with concurrent work on a fundamental revision of the geomagnetic polarity sequence, a comprehensive and detailed new time scale for the Cenozoic will soon be developed.
Adaptation beyond an ideal, a sculptural enquiry

description: To survive and travel within environments that do not accommodate the body, humans have designed tools that allow for adaptation. Through sculptural processes I have investigated the idea that humans construct various aspects of the external world based on a reflected understanding of the internal workings of the human body and its limitations. By drawing on forms such as the lifeboat, sleeping bag, hammock and aeronautical equipment, together with utilising my own dimensions as a design tool I have created a group of non-representational sculptures. It is my intention to explore how these sculptures can evoke possible shelters, adaptive vehicles and imaginary human carapaces. Conceptually this process alludes to structures and vehicles that transport the occupant beyond an imaginary set of physiological confinements. Various industrial materials such as rubber, timber, steel and fabric have been utilised, their inherent qualities contributing to design choices made within the construction process. I have investigated materials and construction techniques that reveal the making process, and present form and surface as problems to be resolved on an equal footing. A significant aspect of the project is the contribution made to the content of the work by time intensive methods of labour, together with specific material choices. Collectively the works share aspects of construction in that a skeletal framework configures each piece: cladding or exposure of this framework varying with each sculpture. Within the project I have researched the work of Lucy Orta, Antony Gormley and Martin Puryear to inform my research about shelter, dimensional design and formal concerns regarding material use and form.

description: Recent Halpha surveys such as SHS and IPHAS have improved the completeness of the Galactic planetary nebula (PN) census. We now know of ~3,000 PNe in the Galaxy, but this is far short of most estimates, typically ~25,000 or more for the total population. The size of the Galactic PN population is required to derive an accurate estimate of the chemical enrichment rates of nitrogen, carbon, and helium. In addition, a high PN count (~20,000) is strong evidence that most 1-8 Msun main sequence stars will go through a PN phase, while a low count (<10,000) argues that special conditions (e.g., a close binary interaction) are required to form a PN. We describe a technique for finding hundreds more PNe using the existing data collections of the digital sky surveys, thereby improving the census of Galactic PNe.

description: We study Archimedean atomic lattice effect algebras whose set of sharp elements is a complete lattice. We show properties of centers, compatibility centers and central atoms of such lattice effect algebras. Moreover, we prove that if such effect algebra $E$ is separable and modular then there exists a faithful state on $E$. Further, if an atomic lattice effect algebra is densely embeddable into a complete lattice effect algebra $\widehat{E}$ and the compatiblity center of $E$ is not a Boolean algebra then there exists an $(o)$-continuous subadditive state on $E$.
Tutorial enhancement and automated code helper

description: This work proposes a system, entitled TEACH (Tutorial Enhancement and Automated Code Helper) which will allow students to complete programming tutorials online with the ability to submit their work to a server for instant analysis and receive meaningful feedback on any errors found with the code. This is achieved through a chosen set of analysis tools which have been brought together as a system and presented here as the \Three Spheres of Analysis\". The building of TEACH will test the hypothesis that students will prefer learning in the newly developed automated tutorial system over the current tutorial system. The results show students are receptive to the system; however are not convinced that it would replace the current tutorial system."
