    The political economy of academic labour markets: How marketisation policies enforce labour market segmentation in Australia and Germany

    The marketisation of higher education has transformed academic labour markets and challenges comparative political economy theory. This thesis explores the tensions between predicted and actual developments of academic labour markets in the liberal Australian and the German corporatist welfare state. It compares the emergence of marketisation policies and their impact on academic labour market developments between 1980-2012 in the two contrasting national higher education systems. The central argument of this thesis is that states develop similar marketisation policies despite clearly different institutional configurations. While these policies are tailored to nationally specific regimes, nevertheless in each case they have triggered the segmentation of academic labour markets into a secure primary and a precarious secondary market. The quantitative evidence shows a growing gap between secure and precarious employment and demonstrates that academic labour markets are more secure in the Australian liberal than in the German coordinated welfare state. This contradicts the premises of comparative political economy and shows that similar marketisation policies, converging processes and outcomes emerge beyond institutional particularities. In accordance with scholars from the new political economy of higher education, this thesis suggests that a combined analysis of macro and micro approaches from the comparative political economy and the sociology of higher education disciplines provide useful means of theorising the changing structures of higher education and academic labour markets

    Cryptobranchus guildayi is described as an extinct species of large salamander that is closely related to the hellbender, Cryptobranchus alleganiensis. The validity of this extinct taxon has been questioned, so an expanded osteological sample of modern hellbenders was used for comparative purposes with the C. guildayi fossil material. Based on this analysis, all supposed distinguishing morphological characteristics used to define C. guildayi can be observed in specimens of C. alleganiensis, or are based on misidentifications. Therefore, Cryptobranchus guildayi is considered to be conspecific with C. alleganiensis and taxonomically should be considered a junior synonym of the latter. The reassignment of the C. guildayi specimens to C. alleganiensis and examination of undescribed fossil specimens from the same region expands the prehistoric range of the species to the Potomac River and its tributaries and also extends the age of the species to the Irvingtonian North American land mammal age

    Objective: Assess the effect of yoga on levels of fatigue among women with breast cancer currently undergoing radiotherapy. Design: Systematic literature review. Methods: Searches were done on PubMed, utilizing the terms “yoga,” “fatigue,” “breast cancer,” and “radiotherapy.” Limits that led to inclusion of studies included: published after 2008, studies researching breast cancer, and studies that were randomized controlled trials. Results: Randomized controlled trials studied were by Chandwani et al. (2010), Chandwani et al. (2014), and Vadiraga et al. (2009). Conclusion: Yoga can improve quality of life among women with breast cancer undergoing radiotherapy, specifically by decreasing levels of fatigue. We recommend that yoga be implemented into treatment plans for women undergoing radiotherapy for breast cancer. Yoga is a cost-effective, safe, and gentle intervention

    Overpressures in the Uinta Basin, Utah: analysis using a three-dimensional basin evolution model

    Get PDF
    Journal ArticleAbstract. High pore fluid pressures, approaching lithostatic, are observed in the deepest sections of the Uinta basin,Utah. Geologic observations and previous modeling studies suggest that the most likely cause of observed overpressure is hydrocarbon generation. We studied Uinta overpressure by developing and applying a three-dimensional, numerical model of the evolution of the basin. The model was developed from a public domain computer code, with addition of a new mesh generator that builds the basin through time, coupling the structural thermal, and hydrodynamic evolution. Also included in the model are in situ hydrocarbon generation and multiphase migration. The modeling study affirmed oil generation as an overpressure mechanism but also elucidated the relative roles of multiphase fluid interaction, oil density and viscosity and sedimentary compaction. An important result is that overpressures by oil generation create conditions for rock fracturing, and associated fracture permeability may regulate or control the propensity to maintain overpressures

    Green urine from propofol

    "A 65-year-old female, with past medical history of hypertension and chronic hypoxemic respiratory failure due to chronic obstructive pulmonary disease (COPD), was admitted after endoscopic resection of colonic polyps and a large rectal mass. For this procedure, general anesthesia with intravenous Propofol was utilized. Due to technical difficulty of the procedure, the total anesthesia time was 7 hours and 48 minutes with a total use of 2,951.06 mg of Propofol. On post-procedure day #1, the patient's urine was noted to be green (Figure 1). The patient denied dysuria, frequency, urgency, and foul smell. Additionally, liver function tests, renal function tests, complete blood count, and urinalysis were all within normal limits."Cole T. Bredehoeft (1), Rebecca T. Rist (2), Christian A.

    Loading and unloading of sedimentary basins: the effect of rheological hysteresis

    Get PDF
    We present a model for the study of the effect of rheological hysteresis on compaction in sedimentary basins, when surface loading and unloading occurs. When compaction is slow (sedimentation rate is large and/or permeability is small), the hysteresis has little effect on the basal compaction layer, but in the more realistic case where compaction is fast (i.e., sedimentation is slow and/or permeability is large), surface unloading leads to downward propagation of a decompaction front, across which the vertical porosity gradient jumps, while subsequent surface reloading leads to downward propagation of a discontinuity in porosity, despite the fact that the porosity is governed by a diffusive equation of Richards type

    Assessing overexploitation in Mediterranean aquifers using system stability condition analysis

    Get PDF
    This paper analyses competitive groundwater exploitation for irrigation by means of a special case of a dynamic predator–prey or human-resource theoretical model. On the human side, the model considers both farmers’ rational behaviour and a set of economic parameters. Then the model explicitly links these issues to the dynamics of the natural resource. Equilibrium states are evaluated, and the drivers and conditions for final states leading to groundwater overexploitation are assessed. The theoretical model finally serves to discuss the long-term sustainability of the processes of transformation from traditional to highly intensive pumping-based agricultural systems. These are processes now taking place in aquifers of southern Spain and Maghreb oases

    In Situ Study of the Physical Mechanisms Controlling Induced Seismicity at Monticello Reservoir, South Carolina

    In two ~1.1-km-deep wells, the magnitudes of the principal in situ stresses, pore pressure, permeability, and the distribution of faults, fractures, and joints were measured directly in the hypocentral zones of earthquakes induced by impoundment of Monticello Reservoir, South Carolina. Analysis of these data suggests that the earthquakes were caused by an increase in subsurface pore pressure sufficiently large to trigger reverse-type fault motion on preexisting fault planes in a zone of relatively large shear stresses near the surface. The measurements indicated (1) near-critical stress differences for reverse-type fault motion at depths less than 200-300 m, (2) possibly increased pore pressure at depth relative to preimpoundment conditions, (3) the existence of fault planes in situ with orientations similar to those determined from composite focal plane mechanisms, and (4) in situ hydraulic diffusivities that agree well with the size of the seismically active area and time over which fluid flow would be expected to migrate into the zone of seismicity. Our physical model of the seismicity suggests that infrequent future earthquakes will occur at Monticello Reservoir as a result of eventual pore fluid diffusion into isolated zones of low permeability. Future seismic activity at Monticello Reservoir is expected to be limited in magnitude by the small dimensions of the seismogenic zones
