description: We investigate the existence and the properties of fully separable (fully factorized) ground states in quantum spin systems. Exploiting techniques of quantum information and entanglement theory we extend a recently introduced method and construct a general, self-contained theory of ground state factorization in frustration free quantum spin models defined on lattices in any spatial dimension and for interactions of arbitrary range. We show that, quite generally, non exactly solvable translationally invariant models in presence of an external uniform magnetic field can admit exact, fully factorized ground state solutions. Unentangled ground states occur at finite values of the Hamiltonian parameters satisfying well defined balancing conditions between the applied field and the interaction strengths. These conditions are analytically determined together with the type of magnetic orderings compatible with factorization and the corresponding values of the fundamental observables such as energy and magnetization. The method is applied to a series of examples of increasing complexity, including translationally-invariant models with short, long, and infinite ranges of interaction, as well as systems with spatial anisotropies, in low and higher dimensions. We also illustrate how the general method, besides yielding a large series of novel exact results for complex models in any dimension, recovers, as particular cases, the results previously achieved on simple models in low dimensions exploiting direct methods based on factorized mean-field ansatz.

description: We investigate the thermal quenching of the multimodal photoluminescence from InAs/InP (001) self-assembled quantum dots. The temperature evolution of the photoluminescence spectra of two samples is followed from 10 K to 300 K. We develop a coupled rate-equation model that includes the effect of carrier thermal escape from a quantum dot to the wetting layer and to the InP matrix, followed by transport, recapture or non-radiative recombination. Our model reproduces the temperature dependence of the emission of each family of quantum dots with a single set of parameters. We find that the main escape mechanism of the carriers confined in the quantum dots is through thermal emission to the wetting layer. The activation energy for this process is found to be close to one-half the energy difference between that of a given family of quantum dots and that of the wetting layer as measured by photoluminescence excitation experiments. This indicates that electron and holes exit the InAs quantum dots as correlated pairs.

description: At Deep Sea Drilling Site 384 (J-Anomaly Ridge, Grand Banks Continental Rise, NW Atlantic Ocean) Paleocene nannofossil chalks and oozes (∼70 m thick) are unconformably/disconformably underlain (∼168 m; upper Maastrichtian) and overlain (∼98.7 m; upper lower Eocene) by sediments of comparable lithologies. The chalks are more indurated in stratigraphically higher levels of the Paleocene reflecting increasing amounts of biosiliceous (radiolarians and diatoms) components. This site serves as an excellent location for an integrated calcareous and siliceous microfossil zonal stratigraphy and stable isotope stratigraphy. We report the results of a magnetostratigraphic study which, when incorporated with published magnetostratigraphic results, reveals an essentially complete magnetostratigraphic record spanning the interval from Magnetochron C31n (late Maastrichtian) to C25n (partim) (late Paleocene, Thanetian). Integrated magnetobiochronology and stable isotope stratigraphy support the interpretation of, and constrain the estimated duration of, a short hiatus (∼0.9 my) within the younger part of Chron C29r (including the K/P boundary) and an ∼6 my hiatus separating upper Paleocene (Magnetozone C25n) and upper lower Eocene (Magnetozone C22r) sediments. Some 30 planktonic foraminiferal datum levels [including the criteria used to denote the Paleocene planktonic foraminiferal (sub)tropical zonal scheme of Berggren and Miller, Micropaleontology 34 (4) (1988) 362–380 and Berggren et al., SEPM Spec. Publ. 54 (1995) 129–212, Geol. Soc. Am. Bull. 107 (11) (1995) 1272–1287], and nearly two dozen calcareous nannoplankton datum levels have been recognized and calibrated to the magnetochronology. Planktonic foraminiferal Subzones P4a and P4b of (upper Paleocene) Zone P4 are emended/redefined based on the discovery of a longer stratigraphic extension of Acarinina subsphaerica (into at last Magnetozone C25n). Stable isotope stratigraphies from benthic foraminifera and fine fraction (<38 μm) carbonate have been calibrated to the biochronology and magnetostratigraphy. A minimum in benthic foraminifer δ13C was reached near the Danian/Selandian boundary (within Chron C26r, planktonic foraminiferal Zone P3a and calcareous nannoplankton Zone NP4) and is followed by the rise to maximum δ13C values in the late Thanetian (near the base of C25n, in Zone P4c and NP9a, respectively) that can be used for global correlation in the Paleocene.
A digital data acquisition system for astronomical spectra

Publisher: name: University of British Columbia
Year: 2011

description: Certain restrictions associated with conventional photographic techniques have led to the use of a low light level television tube (isocon tube) as an alternative detector for astronomical spectra. An on-line digital data acquisition system has been developed to process and analyze data from the television camera. The digital system consists of a high speed analog-to-digital converter, a digital computer with magnetic tape transport and oscilloscope display, and some digital control logic. Spectra displayed on the photocathode of the isocon tube are digitized by the A/D converter and stored on magnetic tape via the computer processor. Data acquisition time for one frame of data (1360 samples) is less than 1.5 seconds. Results obtained with the system indicate that it performs as initially intended and is able to resolve spectral features of the order of 0.1 mm.

description: If E is any ellipse inscribed in a convex quadrilateral, D, then we prove that Area(E)/Area(D) is less than or equal to pi/4, and equality holds if and only if D is a parallelogram and E is tangent to the sides of D at the midpoints. This extends well known results for ellipses inscribed in triangles. We also prove that the foci of the unique ellipse of maximal area inscribed in a parallelogram, D, lie on the orthogonal least squares line for the vertices of D. This does not hold in general for convex quadrilaterals.

description: We measure oscillator phase from the zero crossings of the voltage vs. time waveform of a spin torque nanocontact oscillating in a vortex mode. The power spectrum of the phase noise varies with Fourier frequency $f$ as $1/f^2$, consistent with frequency fluctuations driven by a thermal source. The linewidth implied by phase noise alone is about 70 % of that measured using a spectrum analyzer. A phase-locked loop reduces the phase noise for frequencies within its 3 MHz bandwidth.

title: Prediction and Assessment of Liked and Non-liked Teachers as Rated by Various Student Groups
Creators: name: Fleming, Nancy LaDee
Publisher: name: Utah State University
Year: 1973

description: This study was designed to: (1) determine whether the test scores on the CPI and Teacher Inventory serve as predictors of "liked" and "non-liked" teachers, and (2) determine whether various student groups (minority, Anglo, disadvantaged and non-disadvantaged) rate "liked" and "non-liked" teachers differently on each of the three variables of the Teacher Inventory.
Ninety-two sophomore students, representing race and economic factors rated the 37 teachers of required sophomore subject matter classes on a Like-Dislike Scale and the Teacher Inventory. Two lists were thus generated: (1) teachers to whom various students rated as "liked" teachers, and (2) teachers to whom various students rated as "non-liked." Both groups of teachers were administered the CPI.
The data were analyzed by stepwise multiple regression equation and analysis of variance.
From this study of sophomore high school teachers rated as "liked" and "non-liked" by the students, the following may be concluded:

The Teacher Inventory and CPI test scores are good predictors of teachers rated "liked" or "non-liked" by various student groups. The prediction value was greater than .91.

Liked teachers as compared with the non-liked teachers tend to be perceived by the students as (1) grading more fairly, (2) making class more interesting with a variety of materials and activities, (3) having better class control, (4) being able to answer more of the questions students ask, (5) planning more carefully and utilizing time better, (6) showing more of an interest in the students, (7) adjusting better to different situations that arise in class, (8) friendlier and more cheerful, (9) giving more consideration to the opinions and ideas of the students, (10) more inclined to admit when he is wrong, and (11) appearing to enjoy teaching more.

Liked teachers as compared with the non-liked teachers tend to have these personality characteristics: (1) more methodical, mannerly and cautious, (2) more poised and self-confident, (3) have a better sense of personal worth, (4) more ambitious and resourceful, (5) more inclined to worry and complain, (6) more outgoing, active and impatient, and (7) younger in age (under 35).

Liked teachers tend to relate well with the minority, Anglo, disadvantaged and non-disadvantaged students. There is a significant difference in the minority students' rating of liked teachers. They rate the teachers higher in comparison with other student groups.

Non-liked teachers are significantly (.05) less effective in their teaching relationships with the minority students. On all variables of the Teacher Inventory, non-liked teachers are rated lower than liked teachers.

description: The Berlin Exoplanet Search Telescope II (BEST II) is a small wide field-of-view photometric survey telescope system located at the Observatorio Cerro Armazones, Chile. The high duty cycle combined with excellent observing conditions and millimagnitude photometric precision makes this instrument suitable for ground based support observations for the CoRoT space mission. Photometric data of the CoRoT LRa02 target field collected between November 2008 and March 2009 were analysed for stellar variability. The presented results will help in the future analysis of the CoRoT data, particularly in additional science programs related to variable stars. BEST II observes selected CoRoT target fields ahead of the space mission. The photometric data acquired are searched for stellar variability, periodic variable stars are identified with time series analysis of the obtained stellar light curves. We obtained the light curves of 104335 stars in the CoRoT LRa02 field over 41 nights. Variability was detected in light curves of 3726 stars of which 350 showed a regular period. These stars are, with the exception of 5 previously known variable stars, new discoveries.

description: Performance of data systems are critical in today’s world due to the large amount of data collection being done. Database management systems (DBMS) employ structured files and large amounts of high cost in-place insertions and removals. Traditionally, applications use extra layers of indirection to offset these high cost operations but this only adds more complexity and higher access costs. In the face of this, we utilize a flexible address space located in user space called FlexFile. FlexFile utilizes in-place updates for arbitrary-sized data, which creates a more efficient way for insertions and removal operations to be performed. This research re-implements FlexFile in the Linux kernel and evaluates performance comparisons between both. First, the implementation overview is presented to efficiently realize the user space needs of a traditional file system interface. Next, the current and future implementation possibilities are discussed to perfect and expand this development. Last, both implementation results are compared and contrasted to show how specific locations within a system can be leveraged to produce different results within the FlexFile implementation.
title: Effects of Manipulating FR Size and Reinforcement Magnitude in Multiple FR Schedules
Creators: name: Inman, Dean P.
Publisher: name: Utah State University
Year: 1973

description: Animals performing on simple fixed-ratio (FR) schedules vi typically pause after reinforcement delivery. The present study demonstrated systematic control of pause length in multiple fixed ratio schedules by manipulating FR size and reinforcement magnitude. In Experiment I, two adult male rabbits were stabilized on an alternating, two component, multiple FR 10 FR 10 schedule. Different colored lights were correlated with both FR components. Stability was determined and mean pause lengths were calculated as one FR component was increased in size until the schedule was FR 10 FR 50. Pausing was longer before the large FR component and was positively correlated with increases in FR size. Schedule and stimulus control were demonstrated by randomizing the order of FR presentations and by reversing the colored lights previously correlated with either the small or large FR components. Existing pause differentials were not disrupted under the light reversal or random conditions.
In Experiment II, the same rabbits were stabilized at mult FR 10 FR 30 with 1/2 cc of water delivered after each component. In subsequent conditions the magnitude of reinforcement (cc's of water) delivered at the completion of the large FR component, was systematically shifted from 4 cc, to 3 cc, 2 cc, 1 cc and finally back to 1/2 cc. Pausing before the large FR was found to be inversely related to the magnitude of reinforcement delivered in that component.
Clearly the animals in this experiment discriminated upcoming schedule conditions and paused relative to FR size and reinforcement magnitude. Hence, it is proper to point out that the term "post-reinforcement pause" is a misnomer since it incorrectly implies a functional relation between pause length and prior schedule conditions.

description: The process of electroproduction of the electron-positron pair by high energy electron in an oriented single crystal is investigated. Two contributions are considered: the direct (one-step) process via the virtual intermediate photon and the cascade(two-step) process when the electron emits the real photon moving in the field of axis and afterwards the photon converts into the pair. The spectrum of created positron(electron) is found. It is shown that the probability of the process is strongly enhanced comparing with the corresponding amorphous medium.

description: Samples from two adjacent and contrasting ridge segments along the East Pacific Rise were measured for their magnetic paleointensity in order to further explore the possibilities of dating very young volcanic samples using secular variations in the Earth's magnetic field. The ridge segment north of the Orozco transform fault (15°22′-16°20′N) is the shallowest and broadest along more than 5000 km of the East Pacific Rise, whereas the adjacent segment to the north (16°16′-18°N) has a "typical" morphology for its intermediate spreading rate. Both ridge segments were densely sampled during the PANR01MV cruise and 36 samples of axial lava flows, consisting mainly of glasses from the rims of the flows and some fragments of lobate basalts, were selected from this collection for paleointensity experiments. The Coe version of the Thellier double-heating procedure (in air) was used. Twenty-seven units provide internally consistent paleointensity estimates leading to precise estimates of the paleofield, which range between 8 μT and 57 μT. Comparisons with reference paleointensity curves compiled from subaerial flows, archeomagnetic data and sedimentary records projected to the sampling site coordinates show that the measured values can be used to constrain the volcanic history of the ridge segments over the past few thousand years. A good agreement was found between apparent "freshness" of the glasses, the geochemistry of the lavas, and their magnetic paleointensity values. The inflated southern segment seems characterized by recent activities as indicated by numerous flows with paleointensities clustering around today's value (39 μT) or around the high values typical of 2000-3000 years ago (~55 μT). We interpret this distribution to indicate the flooding by effusive lava flows of the entire axial plateau some 2000-3000 years ago, followed by a volcanic phase producing smaller volume lava flows confined to the innermost 200 m of the ridge axis. The northern ridge segment is characterized by dispersed paleointensity values consistent with a series of small eruptions of diverse ages. Samples collected at the tips of both ridge segments across the 16°20′N axial discontinuity have the lowest paleointensities and are thus thought to be significantly older, consistent with models advocating reduced magmatism near ridge axis discontinuities. This study demonstrates the strong potential of paleointensity measurements as a tool to help constrain volcanic history at ridge axes.
title: The Relationship of Scoring Above or Below the 75th Percentile on the Kuder Preference Record to General Aptitude, Vocational Attitudes and Occupational Values

Publisher: name: Utah State University
Year: 1973

description: This study was designed to investigate the relationship of general aptitude, vocational attitudes, and occupational values to scoring above or below the 75th percentile on the Kuder Preference Record by ninth grade students in rural southwestern Utah and southeastern Idaho.
The sample consisted of a group of 248 students who participated in Project Mace. The students were divided into two groups according to their Kuder percentile scores. The G scale of the General Aptitude Test Battery, the Vocational Development Inventory, and the Occupational Values Inventory were also administered to the subjects. The data were analyzed by a simple correlation matrix and analysis of variance.
The results of the study indicated there was no significant difference between the two groups on any of the instruments.
The implications from the results indicated that:

The 75th percentile probably should not be used as a criterion for strong interests, at least when an attempt is being made to relate interests to the general aptitude, attitudes, and values measured in this study.

More research is needed in order to fully understand the relationship of interests, aptitudes, attitudes and values.

More research is needed on the instruments used in this study, especially the Occupational Values Inventory and the Vocational Development Inventory.
The features and significance of Jingju plays (1790-1911)

Publisher: name: University Of Tasmania
Year: 2023

description: Jingju as a genre has been extensively studied and its performance is not unfamiliar to the Western audience, who know it by the terms \Chinese opera\" or \"Peking opera\". There are however few studies on the texts of jingju plays. The present thesis examines jingju plays written from 1790 to 1911 analyzing their features and achievements. It makes extensive use of texts from the Che Wang Fu Repertoires which have been edited and published only in recent years. It will argue that contrary to the accepted scholarly opinions fin& plays are highly significant because they deal with new ideas reinterpretations of history and the critique of traditions. The thesis devotes each chapter to one major subject area in jingju plays. They are: Marketplace Play and Love Story Play produced during the incubating period of jingju History Play Courtroom Play and Frontier Fortress Play created during the later stage of the development of jingju. In dealing with each area the thesis will analyze the achievements and significance of the texts of jingju plays. Developed from various popular xiqu in the late eighteenth and nineteenth century jingju plays arose at a time when the traditional Chinese hierarchical society was on the verge of collapse. In the depiction of daily life or matters involving historical or ideological issues jingju playwrights raised a number of major questions not touched on by classical xiqu playwrights. Jingju playwrights have achieved breakthroughs in their criticisms of traditional culture traditional moral codes and The thesis argues that three main factors contributed to the breakthroughs of jingju plays. Firstly commercialism played an important role in the rise of popular playwrights and the expansion of popular arts and literature in the later periods of Chinese traditional society particularly in the late Qing. Another factor was political. The abolition of the official musician prostitutes for example facilitated the further commercialization of the performing arts. The third factor was literary. Jingju playwrights inherited new ideas plots characterization and settings of popular literature such as popular novels."

description: Geographic borders are not only essential for the effective functioning of government, the distribution of administrative responsibilities and the allocation of public resources, they also influence the interregional flow of information, cross-border trade operations, the diffusion of innovation and technology, and the spatial spread of infectious diseases. However, as growing interactions and mobility across long distances, cultural, and political borders continue to amplify the small world effect and effectively decrease the relative importance of local interactions, it is difficult to assess the location and structure of effective borders that may play the most significant role in mobility-driven processes. The paradigm of spatially coherent communities may no longer be a plausible one, and it is unclear what structures emerge from the interplay of interactions and activities across spatial scales. Here we analyse a multi-scale proxy network for human mobility that incorporates travel across a few to a few thousand kilometres. We determine an effective system of geographically continuous borders implicitly encoded in multi-scale mobility patterns. We find that effective large scale boundaries define spatially coherent subdivisions and only partially coincide with administrative borders. We find that spatial coherence is partially lost if only long range traffic is taken into account and show that prevalent models for multi-scale mobility networks cannot account for the observed patterns. These results will allow for new types of quantitative, comparative analyses of multi-scale interaction networks in general and may provide insight into a multitude of spatiotemporal phenomena generated by human activity.

description: We present a summary evaluation of the distribution and qualitative ranking of the Plio-Pleistocene magnetostratigraphic results obtained to date from Deep Sea Drilling Project and Ocean Drilling Program piston-cored sites. A review of the published magnetostratigraphic records provides insights into the important extrinsic and intrinsic factors which affect the quality of the paleomagnetic records. The extrinsic factors originate with drilling processes, such as core barrel remagnetization, and steps can be taken to reduce these effects and improve the data quality. The distribution of the high-quality records correlates well both with areas of terrigenous sediment input as well as regions of moderate biological productivity. This suggests that important intrinsic factors include the origin of the original magnetic carrier in the sediment (lithogenic or biogenic) and the degree to which the magnetic carrier has been affected by reduction diagenesis.
title: Its Reevaluation and Improvement As Related To A Profile Analysis Classification System

description: Over the first half of the present study the Mini-Mult (MM1), a brief form of the Minnesota Multiphasic Personality Inventory (MMPI), was compared with the standard MMPI in relation to eleven criteria classifications. These criteria were composed of the profile analysis classifications of Marks and Seeman (1963). Pearson product-moment correlations between the MM1 and MMPI failed to reach statistical significance for any of the eleven criteria.
As based on the information gained, a correction factor was devised and added to the MM1. Subsequently, the second half of the study involved a comparison between the HMPI and the revised MM. This revised test was termed the MM2. In only two of eleven criteria cases did the correlation between the MM2 and MMPI reach statistical significance. However, for nine of the eleven criteria the MM2 did obtain a higher positive correlation with the MMPI than did the MM1.
Such results indicate that the proposed correction factor is a step in the right direction and deserving of continued investigation.
Although the MM2 as it presently stands cannot be validy substituted for the MMPI, continued research in the area of modifying its correction factor can yield it a useful clinical tool.

description: The See-Saw mechanism provides a nice way to explain why neutrino masses are so much lighter than their charged lepton partners. It also provides a nice way to explain baryon asymmetry in our universe via the leptogenesis mechanism. In this talk we review leptogenesis and LHC physics in a See-Saw model proposed in 1989, now termed the Type III See-Saw model. In this model, $SU(2)_L$ triplet leptons are introduced with the neutral particles of the triplets playing the role of See-Saw. The triplet leptons have charged partners with standard model gauge interactions resulting in many new features. The gauge interactions of these particles make it easier for leptognesis with low masses, as low as a TeV is possible. The gauge interactions also make the production and detection of triplet leptons at LHC possible. The See-Saw mechanism and leptogenesis due to Type III See-Saw may be tested at LHC.

title: An Analysis of the Effects of Delay of Reinforcement and Momentary Probabilities of Reinforcement on Interval Schedule Performance
Creators: name: Lund, Charles A.
Publisher: name: Utah State University
Year: 1973

description: In two experiments pigeons were exposed to VI and FI schedules and viii schedules approximating both VI and FI schedules. In experiment I, the probabilities of the VI and FI components in a Mixed FI VI schedule were manipulated to create schedule contingencies approximating simple VI or FI. In experiment II, the minimum and maximum inter-reinforcement intervals were manipulated to create schedule contingencies approximating simple VI or FI. The major finding of both of these experiments was that maximal control by the dimension of time occurred as FI contingencies were approximated. Control by any one temporal value in experiment I depended on its temporal separation from 100 seconds and the probability of reinforcement associated with 100 seconds. Control by any one temporal value in experiment II depended on its temporal separation from the minimum inter-reinforcement interval and 100 seconds. The results were discussed in terms of interval schedule control as a form of stimulus control.
A third experiment was performed to examine possible relationships between the pause in FI performance and the subsequent scallop. The baseline condition was contaminated by a procedure which may have produced effects which overrode experimental manipulations.
Finally, an experiment was suggested to demonstrate behavioral contrast along a temporal dimension. The argument that interval schedule control is a form of stimulus control rested on analogy and inference. A demonstration of behavioral contrast along a temporal dimension would demonstrate more directly that time is similar to other dimensions. Hence, the same principles could be used to explain schedule control as are used to explain stimulus control.
A comparison of first time and repeat intentional self-poisoning patients
Creators: name: Driscoll, Carolyn
Publisher: name: University Of Tasmania
Year: 2023

description: Identifying the characteristics associated with those who make repeat suicide attempts by intentional self-poisoning is important for improving treatments and reducing the risk of further attempts and completed suicide. Limited previous research has been conducted examining this group, typically focussing on demographic and psychopathological characteristics and overlooking some important cognitive-behavioural factors and psychophysiology. In addition, the research has primarily focussed on restricted samples such as psychiatric inpatients and has lacked a consistent definition of the concept of repetition. The present research takes a process-based approach by comparing a first attempt group with a repeat attempt group and a community control group with the aim of developing a profile of those who repeat in a clinical adult sample. The first two studies in this research develop descriptive and cognitive-behavioural profiles with the results indicating similarity between the first time and repeat groups. However, the repeat group was differentiated from the first time group by more severe symptomatology, less impulsiveness in taking the overdose, and a greater likelihood of reporting tension reduction reasons for the overdose. In addition, the repeat group experienced significantly greater levels of hopelessness and reported poorer perceived problem solving skills and severely impaired coping resources. The third study extended this profile by examining the psychophysiological and subjective experience of the overdose using guided imagery. The results indicated that the first time and repeat groups demonstrated almost identical psychophysiological and subjective experiences during the process of taking the overdose which reflected a tension reduction pattern. It was concluded from this research that the differences between the first time and repeat groups appear to be quantitative rather than qualitative with the repeat group reflecting more severe symptomatology and cognitive-behavioural impairments, supporting a process approach to suicidal behaviours s. It is not clear from this research if the differential characteristics of the repeat group are vulnerabilities present before the first suicide attempt or represent a deterioration of these factors over time and with subsequent attempts.

description: The Upper Triassic Fleming Fjord Formation of the Jameson Land Basin in East Greenland contains a well-exposed succession, 200–300 m thick, of lake deposits. The Malmros Klint Member, 100–130 m thick, is composed of cyclically bedded intraformational conglomerates, red siltstones and fine-grained sandstones and disrupted dolomitic sediments (paleosols). The cyclicity is composite with cycles having mean thicknesses of (25), 5.9 and 1.6 m. The overlying Carlsberg Fjord beds of the Ørsted Dal Member, 80–115 m thick, are composed of structureless red mudstones rhythmically broken by thin greyish siltstones. This unit also has a composite cyclicity with cycles having mean thicknesses of 5.0 and 1.0 m. The uppermost Tait Bjerg Beds of the Ørsted Dal Member, 50–65 m thick, can be divided into two units. A lower unit is composed of cyclically bedded intraformational conglomerates or thin sandstones, red mudstones, greenish mudstones and yellowish marlstones. An upper unit is composed of relatively simple cycles of grey mudstones and yellowish marlstones. Recognized cycles have mean thicknesses of 5.6 and 1.6 m. The lake deposits contain evidence of seasonal, orbital and long-term climatic change. Seasonal change is documented by numerous desiccation surfaces especially in the Malmros Klint Member and Carlsberg Fjord beds, orbital change is suggested by the composite cyclicity, and long-term climatic change is indicated by the systematic upwards change in sedimentary characteristics of the lake deposits. The sedimentary features of the Malmros Klint Member suggest lacustrine deposition in a dry climate that fluctuated between desert and steppe conditions, the Carlsberg Fjord beds probably record lacustrine lake deposition in a rather constant dry (steppe) climate, while the Tait Bjerg Beds record lake sedimentation in a climate that fluctuated between dry (steppe) and warm moist temperate. In the Tait Bjerg Beds the upward change in cycle characteristics indicates a shift towards more humid conditions. Climatic deductions from sedimentary facies are in good agreement with climate maps of Laurasia, as simulated by numerical climate models. Palaeomagnetic data indicate a northward drift of East Greenland of about 10° from ca. 25°N to ca. 35°N in the Middle to Late Triassic. The Fleming Fjord Formation which represents ca. 5 m.y. of the Late Triassic interval was deposited during latitudinal drift of 1–2°. It is possible that the observed long-term upward shift in climatic indicators within the formation can be ascribed to plate drift, but southward shift of climatic belts could also have been of importance.

description: Paleomagnetic studies of basalts and sediments from the Dumisseau Formation show that: 1) The basalt magnetizations are characterized by very low coercivlty components. The sediments have generally higher but more variable stabilities against alternating field (AF) treatment compared to the basalts. The 200 oe AF mean directions for the Dumlsseau basalt and sediment sites tend to fall near the present geomagnetic dipole field direction corresponding to the Latitude of Haiti. It is suggested that these rocks carry predominantly secondary magnetization of recent origin and there is little evidence for the preservation of remanent magnetization which may correspond to the time of formation of the rock units in the Late Cretaceous. 2) The remanent magnetic properties of the basalts, particularly those from the upper part of the formation in the Dumisseau area, are very similar to those reported for basalts recovered in the Caribbean DSDP Leg 15, Sites 146, 150, 151, 152 and 153, suggesting also similarities in their petrotectonic origin.
Infectious Intruders, Helpless Hawaiians: Public Health and Race-Making in Colonial Hawai‘i, 1887-1917

description: This dissertation explores the relationship between public health and race-making in Hawaiian Islands, from the last years of the independent Kingdom of Hawai‘i through the first two decades of American rule. During this period, it was a commonplace among white colonists that Native Hawaiians were a “dying race.” Going beyond the black/white binary implicit in most scholarship on race in the United States, this work traces how fears of Asian immigrants intertwined with ideas about Native vulnerability to disease. It argues that public health practices helped to position white colonizers as the natural benefactors of Native Hawaiians, while casting persons of Chinese and Japanese heritage as foreign, subversive, and dangerous to public health.
Epidemiology of Botrytis spp. associated with neck rot of onion (Allium cepa L.) in northern Tasmania, Australia

description: Neck rot of onion, caused by a complex of Botrytis spp., is an important fungal disease of onion worldwide. In Tasmania, it has caused considerable losses to the onion industry in some seasons. Botrytis infects the onion plant in the field but usually the infection remains symptomless, with the fungus growing into the bulb during curing and producing a rot of the bulb in storage. The taxonomy of Botrytis species causing onion neck rot is currently under review. Recent studies of the ribosomal internal transcribed spacer (ITS) region of the genome of Botrytis spp. associated with neck rot have confirmed the existence of three distinct groups. A preliminary study of 24 isolates' from Australia identified one isolate as B. aclada type Al, and 22 isolates as.B. aclada type All (B. allii) with no isolates of B. byssoidea found. A survey of 16 commercial onion bulb crops in northern Tasmania from October to December of 1999 detected B. allii in leaf samples from six crops at an incidence of 0.1% to 0.3%. In three crops that were re-sampled in January 2000, incidence had increased from 0.1% to 3.2%, 0% to 0.5% and 0.3% to 5.8%. Infected crops were found in both main onion-growing regions (northwest and the northeast) in Tasmania. After storage of bulb samples from eight of the surveyed crops, the incidence of Botrytis neck rot ranged from 0.4% to 16.3% with an average incidence of 5.3%. Two field trials were conducted to examine the spatio-temporal spread of B. allii during the season from a point source (2000) and line source (2001). Data of B. cinerea spatio-temporal spread was also collected. In 2000, 100 plots (1.60 by 4.48 m) ‚Äö were established in a 10-by-10 lattice. Leaf samples were taken six times during the growing season and incubated under high humidity to determine the incidence of B. allii in foliage. The incidence of B. allii increased from 0.0% at placement of inoculum (150 days after sowing) to a cumulative 3.8% and a non-cumulative 1.8% at 84 days after placement of inoculum (234 days after sowing). The cumulative sample method was based on always treating a plant as infected once it was found to be infected. The non-cumulative sampling method was the incidence found at each sample time. The disease progress curve was described best by exponential and logistic models (P = 0.001, R2 = 0.99), indicating secondary spread of the pathogen. The disease gradient was steep and best described by an exponential model, usually indicative of a rain splash-dispersed pathogen. Spatial analysis using ordinary runs analysis, beta-binomial distribution analysis, spatial analysis by distance indices and radial correlation analysis determined that the pattern of infection was aggregated.

description: Estimates of regional climate warming over the past few hundred years are being obtained from profiles of borehole temperature versus depth. The assumptions in recovering mean annual Surface Air Temperature (SAT) are that the relationship between the Ground Surface Temperature (GST) and the temperature-depth profile is purely conductive, and that SAT is uniquely coupled to GST. While these assumptions have been demonstrated to be approximately valid, they ignore the role of moisture transport in soil between soil and atmosphere. In this study we examine the influence of climatic changes in precipitation upon mean annual GST with climatic SAT held constant. We use the most recent version of our Prairie SVAT model for a set of 80 years simulations. Our findings are 10 increasing precipitation reduces mean annual GST, 2) phasing maximum precipitation to occur during the warmest months reduces mean annual GST, and 3) increasing the variance of precipitation reduces mean annual GST. The amplitudes of the effects are small but potentially not insignificant fractions of the geothermal climate signal. One of the long-term objectives of this investigation is to use global EOS SAT and remotely sensed soil moisture to link region-specific, geothermal climate signal histories to evolution of regional climate.
A feasibility study for a portable long period seismograph

description: As a preliminary study to the operation of a portable long period seismic system, the effects of environment on the phase response of the Sprengnether 201 and Geotech SL-210 long period vertical seismometers are investigated. It is found that changes in the phase response of the seismometers are related to the zero instability of the moving mass. Pressure changes are not important in this regard; however, temperature variations should be held to less than 1°C. Calculation of the phase response directly from the amplitude response is investigated. It is concluded that it is more practical to carry out a phase calibration directly. The technique may however be useful when only an amplitude calibration is known. Also investigated are the noise properties of two amplifiers: the solid state Geotech AS-330 and the phototube Geotech 12613 amplifiers. The fundamental noise of the seismometer-amplifier combination is negligible. The excess noise of the AS-330 amplifier is of the same order as seismic noise at long periods at a rather noisy site.
