description: Η παρούσα διπλωματική εργασία αποσκοπεί στη διερεύνηση του πεδίου των κρυπτονομισμάτων και των έξυπνων συμβάσεων (Smart Contracts) κυρίως από νομική άποψη. Συζητείται το αναπτυσσόμενο ρυθμιστικό πλαίσιο και οι προκλήσεις που αυτό συνεπάγεται, ιδίως σε σχέση με το Ethereum σε σύγκριση με το Bitcoin. Στο θεωρητικό μέρος της διατριβής εξετάζονται οι βασικοί ορισμοί, σκιαγραφείται το προφίλ και η λειτουργία του περιβάλλοντος των κρυπτονομισμάτων και της blockchain, καθώς και αναλύονται τα θεμελιώδη νομικά ζητήματα που προκύπτουν από τις έξυπνες συμβάσεις. Στο εμπειρικό μέρος της διατριβής, το αινιγματικό και ενίοτε, ανεπαρκές νομικό πλαίσιο τόσο στην ΕΕ όσο και στην Ελλάδα αναδεικνύεται ως πρακτική μελέτη περίπτωσης. Το ισχύον νομικό και ρυθμιστικό πλαίσιο είναι εκκολαπτόμενο, παρουσιάζοντας σημαντικά νομικά κενά σχετικά με τα κρυπτονομίσματα και τις έξυπνες συμβάσεις στη θεωρία και την πράξη. Ωστόσο, υπάρχουν πράγματι βιώσιμες προτάσεις για περαιτέρω έρευνα και εφαρμογή.

description: American students are increasingly accessing higher education (U.S. Department of Education, 2016a); yet, only 60% of first-time, full-time students will complete a bachelor’s degree within six years (U. S. Department of Education, 2016b). While these are current statistics, opportunity programs were instituted in the 1960s to address issues of access, acclimation, and navigation in college, specifically for low-income, first-generation college students. Due to the limited financial, human, and physical resources available in opportunity programs, not all students can participate even if they desire to and meet the criteria. Thus, unaffiliated students must navigate college using their own resources and college knowledge, which requires the attainment and deployment of capital. The present phenomenological study sought to understand the college navigation experiences of low-income, first-generation Black women undergraduates at a historically white institution (HWI), particularly as Black women account for the bulk of the increase in college enrollment rates (Banks, 2009; Gold, 2011; USDOE, 2016c). Community Cultural Wealth (CCW) (Yosso, 2005) provides the framework for analysis. Limited research about Black females in higher education, except relative to Black males or white women necessitates this study employ the lens of standpoint theory, which enables the population of study to have agency in the telling of their stories (Collins, 2000; Harding, 2004; Heckman, 1997). Via semi-structured interviews of eight low-income, first-generation Black college women who are not affiliated with opportunity programs and a follow-up focus group with six of these eight women, the study asked how the participants navigated college and what kinds of CCW they used to do so. The following themes emerged from the research: resources at the college; resources outside the college; view of the college; invisibility and visibility; and double-consciousness. Study findings suggest that participants deployed multiple forms of CCW to navigate unwelcoming spaces, connect with others, create communities of support, challenge unsupportive administrators and policies, and advocate for themselves. Recommendations for educators are also discussed.

description: Exposome research can improve the understanding of the mechanistic connections between exposures and health to help mitigate adverse health outcomes across the life span. The exposomic approach provides a risk profile instead of single predictors and thus is particularly applicable to allergic diseases and asthma. Under the PRACTALL collaboration between the European Academy of Allergy and Clinical Immunology (EAACI) and the American Academy of Allergy, Asthma, and Immunology (AAAAI), we evaluated the current concepts and the unmet needs on the role of the exposome in allergic diseases and asthma.

description: We have previously analyzed sensitive mid-infrared observations to establish that the Pipe Nebula has a very low star-formation efficiency. That study focused on YSOs with excess infrared emission (i.e, protostars and pre-main sequence stars with disks), however, and could have missed a population of more evolved pre-main sequence stars or Class III objects (i.e., young stars with dissipated disks that no longer show excess infrared emission). Evolved pre-main sequence stars are X-ray bright, so we have used ROSAT All-Sky Survey data to search for diskless pre-main sequence stars throughout the Pipe Nebula. We have also analyzed archival XMM-Newton observations of three prominent areas within the Pipe: Barnard 59, containing a known cluster of young stellar objects; Barnard 68, a dense core that has yet to form stars; and the Pipe molecular ring, a high-extinction region in the bowl of the Pipe. We additionally characterize the X-ray properties of YSOs in Barnard 59. The ROSAT and XMM-Newton data provide no indication of a significant population of more evolved pre-main sequence stars within the Pipe, reinforcing our previous measurement of the Pipe's very low star formation efficiency.

Search for New Physics in Dijet Mass and Angular Distributions in pp Collisions at sqrt(s) = 7 TeV Measured with the ATLAS Detector

description: A search for new interactions and resonances produced in LHC proton-proton (pp) collisions at a centre-of-mass energy sqrt(s)= 7 TeV has been performed with the ATLAS detector. Using a data set with an integrated luminosity of 36 pb-1 dijet mass and angular distributions have been measured up to dijet masses of \sim 3.5 TeV and found to be in good agreement with Standard Model predictions. This analysis sets limits at 95% C.L. on various models for new physics: an excited quark is excluded with mass between 0.60 and 2.64 TeV, an axigluon hypothesis is excluded for axigluon masses between 0.60 and 2.10 TeV and Randall-Meade quantum black holes are excluded in models with six extra space-time dimensions for quantum gravity scales between 0.75 and 3.67 TeV. Production cross section limits as a function of dijet mass are set using a simplified Gaussian signal model to facilitate comparisons with other hypotheses. Analysis of the dijet angular distribution using a novel technique 18 simultaneously employing the dijet mass excludes quark contact interactions with a compositeness scale Λ below 9.5 TeV.

description: We report on the synthesis of large single crystals of a new FeSe-layer superconductor Cs0.8(FeSe0.98)2. X-ray powder diffraction, neutron powder-diffraction and magnetization measurements have been used to compare the crystal structure and the magnetic properties of Cs0.8(FeSe0.98)2 with those of the recently discovered potassium intercalated system KxFe2Se2. The new compound Cs0.8(FeSe0.98)2 shows a slightly lower superconducting transition temperature (Tc=27.4 K) in comparison to 29.5 in K0.8(FeSe0.98)2). The volume of the crystal unit cell increases by replacing K by Cs - the c-parameter grows from 14.1353(13) Å to 15.2846(11) Å. For the so far known alkali metal intercalated layered compounds (K0.8Fe2Se2 and Cs0.8(FeSe0.98)2) the Tc dependence on the anion height (distance between Fe-layers and Se-layers) was found to be analogous to those reported for As-containing Fe-superconductors and Fe(Se1-xChx), where Ch=Te, S.

description: Results of the first comprehensive light pollution survey in Hong Kong are presented. The night-sky brightness was measured and monitored around the city using a portable light sensing device called the Sky Quality Meter over a 15-month period beginning in March 2008. A total of 1,957 data sets were taken at 199 distinct locations, including urban and rural sites covering all 18 Administrative Districts of Hong Kong. The survey shows that the environmental light pollution problem in Hong Kong is severe - the urban night-skies (sky brightness at 15.0 mag per arcsec square) are on average ~100 times brighter than at the darkest rural sites (20.1 mag per arcsec square), indicating that the high lighting densities in the densely populated residential and commercial areas lead to light pollution. In the worst polluted urban location studied, the night-sky at 13.2 mag per arcsec square can be over 500 times brighter than the darkest sites in Hong Kong. The observed night-sky brightness is found to be affected by human factors such as land utilization and population density of the observation sites, together with meteorological and/or environmental factors. Moreover, earlier night-skies (at 9:30pm local time) are generally brighter than later time (at 11:30pm), which can be attributed to some public and commercial lightings being turned off later at night. On the other hand, no concrete relationship between the observed sky brightness and air pollutant concentrations could be established with the limited survey sampling. Results from this survey will serve as an important database for the public to assess whether new rules and regulations are necessary to control the use of outdoor lightings in Hong Kong.

description: Significant advancements are being made in the field of interventions for structural heart diseases, driven by the expansion of guideline-directed indications and an increasing patient population requiring intervention or re-intervention for valvular heart disease. Precise diagnosis, optimum timing of intervention, and optimal device selection are essential for successful management. This thesis emphasizes the importance of adopting multimodality imaging, including including echocardiography, angiography, magnetic resonance imaging (MRI), and cardiac computed tomography (CT), in planning, guiding, and evaluating structural heart interventions. These imaging approaches are crucial for patient selection, procedural planning, and post-procedural outcomes assessment.

Characterizations of boreal anthropogenic disturbance regimes from multi-scalar Earth observations
Creators: name: Pickell, Paul Drew
Publisher: name: University of British Columbia
Year: 2015

description: Anthropogenic disturbance regimes are anticipated to overwhelm Earth’s ecosystems during the Anthropocene. Boreal forests are particularly at risk of significant transition due to human appropriation of renewable and non-renewable resources. Forestry and energy development in the boreal forest have three primary ecological consequences: suppression of historical disturbance regimes such as fire; emergence of novel ecosystems; and the eradication of ecological memory, which maintains ecological integrity. The objective of this dissertation is to improve our understanding of the pattern characteristics of anthropogenic disturbance regimes in order to mitigate the negative, unintended outcomes of managed boreal forests. Anthropogenic disturbance from forest harvesting and energy development was mapped for industrialized landscapes of Alberta, Canada between 1949 and 2012. A comparative analysis using spatial models of unsuppressed fires sampled across Alberta and Saskatchewan and aerially-interpreted forest inventory data revealed that the anthropogenic disturbance patterns were beyond the historical range-of-variability in terms of disturbed area, largest patch size, and undisturbed forest remnants. When the spatial data were segmented based on a recent period of intensive energy development, it was determined that energy development in Alberta was a major driver of cumulative anthropogenic disturbance patterns. Levels of undisturbed forest remnants within anthropogenic disturbances declined between 18-34% and edge density increased between 15-175% following energy development. Landscape-level patterns of forest cover changes were assessed using a time series of satellite imagery between 1985 and 2010. Forest disturbance was classified as resource extraction or fire in the Foothills of Alberta with 94% overall accuracy. The rate of resource extraction exceeded fire, accounting for 86% of annual forest disturbance, indicating that fire was suppressed in the landscape. A time series pattern analysis approach applied across Canada demonstrated that managed boreal forests were associated with rising edge density, declining core forest cover, and declining largest forest patch size. Boreal forests that had low disturbance rates were characterized by inherent forest cover pattern variation. This dissertation advanced new perspectives on conceptualizing, detecting, and characterizing patterns of anthropogenic disturbance regimes. Future work is identified primarily around the development and interpretation of landscape structure thresholds and transition indicators.

description: Although the Greenland ice sheet is losing mass as a whole, patterns of change on both local and regional scales are complex. Spatial statistics reveal large spatial variability of dynamic thinning rates of Greenland’s marine-terminating glaciers between 2003 and 2009; only 18% of glacier thinning rates co-vary with neighboring glaciers. Most spatially-correlated thinning rates are clusters of stable glaciers in the Thule, Scoresby Sund, and Southwest regions. Conversely, where spatial-autocorrelation is low, individual glaciers are more strongly controlled by local, glacier-scale features than by regional influences. We investigate possible sources of local control of oceanic forcing by combining grounding line depths and ocean model output to estimate mean ocean heat content adjacent to 74 glaciers. Linear regression models indicate stronger correlation of dynamic thinning rates with ocean heat content compared to those with grounding line depths alone. The correlation between ocean heat and dynamic thinning is robust for all of Greenland except glaciers in the West, and strongest in the Southeast (R2 ∼ 0.81 ± 0.15, ρ = 0.009), implying that glaciers with deeper grounded termini here are most sensitive to changes in ocean forcing. In the Northwest, accounting for shallow sills in the regressions improves the correlation of water depth with glacial thinning, highlighting the need for comprehensive knowledge of fjord geometry.

description: The purpose of this paper is to give an overview in the realm of numerical computations of polydispersed turbulent two-phase flows, using a mean-field/PDF approach. In this approach, the numerical solution is obtained by resorting to a hybrid method where the mean fluid properties are computed by solving mean-field (RANS) equations with a classical finite volume procedure whereas the local instantaneous properties of the particles are determined by solving stochastic differential equations (SDEs). The fundamentals of the general formalism are recalled and particular attention is focused on a specific theoretical issue: the treatment of the multiscale character of the dynamics of the discrete particles, that is the consistency of the system of SDEs in asymptotic cases. Then, the main lines of the particle/mesh algorithm are given and some specific problems, related to the integration of the SDEs, are discussed, for example, issues related to the specificity of the treatment of the averaging and projection operators, the time integration of the SDEs (weak numerical schemes consistent with all asymptotic cases), and the computation of the source terms. Practical simulations, for three different flows, are performed in order to demonstrate the ability of both the models and the numerics to cope with the stringent specificities of polydispersed turbulent two-phase flows.

*-Clean Rings; Some Clean and Almost Clean Baer *-rings and von Neumann Algebras

description: A ring is clean (resp. almost clean) if each of its elements is the sum of a unit (resp. regular element) and an idempotent. In this paper we define the analogous notion for *-rings: a *-ring is *-clean (resp. almost *-clean) if its every element is the sum of a unit (resp. regular element) and a projection. Although *-clean is a stronger notion than clean, for some *-rings we demonstrate that it is more natural to use. The theorem on cleanness of unit-regular rings from [V. P. Camillo, D. Khurana, A Characterization of Unit Regular Rings, Communications in Algebra, 29 (5) (2001) 2293-2295] is modified for *-cleanness of *-regular rings that are abelian (or reduced or Armendariz). Using this result, it is shown that all finite, type I Baer *-rings that satisfy certain axioms (considered in [S. K. Berberian, Baer *-rings, Die Grundlehren der mathematischen Wissenschaften 195, Springer-Verlag, Berlin-Heidelberg-New York, 1972] and [L. Vas, Dimension and Torsion Theories for a Class of Baer *-Rings, Journal of Algebra, 289 (2) (2005) 614-639]) are almost *-clean. In particular, we obtain that all finite type I AW*-algebras (thus all finite type I von Neumann algebras as well) are almost *-clean. We also prove that for a Baer *-ring satisfying the same axioms, the following properties are equivalent: regular, unit-regular, left (right) morphic and left (right) quasi-morphic. If such a ring is finite and type I, it is *-clean. Finally, we present some examples related to group von Neumann algebras and list some open problems.

description: Petermann Glacier is a major glacier in northern Greenland, maintaining one of the few remaining floating ice tongues in Greenland. Monitoring programs, such as NASA’s Operation IceBridge have surveyed Petermann Glacier over several decades and have found it to be stable in terms of mass balance, velocity and grounding-line position. The future vulnerability of this large glacier to changing ocean temperatures and climate depends on the ocean–ice interactions beneath its floating tongue. These cannot currently be predicted due to a lack of knowledge of the bathymetry underneath the ice tongue. Here we use aerogravity data from Operation IceBridge, together with airborne radar and laser data and shipborne bathymetry-soundings to model the bathymetry beneath the Petermann ice tongue. We find a basement-cored inner sill at 540–610 m depth that results in a water cavity with minimum thickness of 400 m about 25 km from the grounding line. The sill is coincident with the location of the melt rate minimum. Seaward of the sill the fjord is strongly asymmetric. The deepest point occurs on the eastern side of the fjord at 1150 m, 600 m deeper than on the western side. This asymmetry is due to a sedimentary deposit on the western side of the fjord. A 350–410 m-deep outer sill, also mapped by marine surveys, marks the seaward end of the fjord. This outer sill is aligned with the proposed Last Glacial Maximum (LGM) grounding-line position for Petermann Glacier. The inner sill likely provided a stable pinning point for the grounding line in the past, punctuating the retreat of Petermann Glacier since the LGM.

Symphonie praxis : a suite exploring faculty experiences and policy frames surrounding digital technologies in British Columbia's post-secondary education system
Creators: name: Gratham, Christopher Hamilton
Publisher: name: University of British Columbia
Year: 2015

description: This study explores faculty members’ lived experiences with digital technologies in their teaching practice at British Columbia University (BCU), and it investigates these individual experiences within overlapping and interrelated contexts at the global, provincial, and institutional scales. The study was inspired by the researcher’s practice in educational technology leadership at BCU and those experiences, along with the researcher’s perspective as geographer, are seen throughout the study. The research is informed by critical theory of technology to situate the different perspectives used to frame technologies. It draws upon research on globalization to analyze provincial and institutional policy documents. It also draws upon Bourdieu’s ideas on capital to understand power and influence shifts: particularly within the institution and how participants’ capital shifts over time. The study illustrates the complex and sometimes contradictory ways that faculty members see their relationship with digital technologies in their practice, and it highlights how government priorities can become institutional policy and ultimately manifest in faculty members experiences. The study shows how the role of the instructor and the field of higher education are changing, and it situates increasingly ubiquitous digital technologies in the change. It illustrates how participants attribute tensions in their practice to different logics between themselves and BCU administrators. And it shows how participants take on the responsibility themselves of increasing their use of digital technologies, even when they don’t believe more technology use will help their practice. This research contributes to the ongoing discussions regarding higher education policy and the roles for digital technologies within that field.

Using the phenomenological Lagrangian approach, we studied its radiative and strong decay properties. We find that our model with about 97.6% isospin zero component explains the existing data nicely. We predict the partial widths of the radiative and strong decays of X(3872) and show that the measurement of the ratio $\mathcal{B}(X(3872) \to χ_{c0}π^0)/\mathcal{B}(X(3872) \to χ_{c1}π^0)$ may signal the nature of X(3872).

description: Gravity surveying is challenging in Antarctica because of its hostile environment and inaccessibility. Nevertheless, many ground-based, airborne, and shipborne gravity campaigns have been completed by the geophysical and geodetic communities since the 1980s. We present the first modern Antarctic-wide gravity data compilation derived from 13 million data points covering an area of 10 million km2, which corresponds to 73% coverage of the continent. The remove-compute-restore technique was applied for gridding, which facilitated leveling of the different gravity data sets with respect to an Earth gravity model derived from satellite data alone. The resulting free-air and Bouguer gravity anomaly grids of 10 km resolution are publicly available. These grids will enable new high-resolution combined Earth gravity models to be derived and represent a major step forward toward solving the geodetic polar data gap problem. They provide a new tool to investigate continental-scale lithospheric structure and geological evolution of Antarctica.
Optogenetic investigation of neuronal excitability and sensory-motor function following a transient global ischemia in mice
Creators: name: Xie, Yicheng
Publisher: name: University of British Columbia
Year: 2015

description: Global ischemia occurs during cardiac arrest and has been implicated as a complication that can occur during cardiac surgery. It induces delayed neuronal death in human and animal models, particularly in the hippocampus, while it also can affect the cortex. Other than morphology and measures of cell death, relatively few studies have examined neuronal networks and motor-sensory function following reversible global ischemia in vivo. Optogenetics allows the combination of genetics and optics to control or monitor cells in living tissues. Here, I adapted optogenetics to examine neuronal excitability and motor function in the mouse cortex following a transient global ischemia. Following optogenetic stimulation, I recorded electrical signals from direct stimulation to targeted neuronal populations before and after a 5 min transient global ischemia. I found that both excitatory and inhibitory neuronal network in the somatosensory cortex exhibited prolonged suppression of synaptic transmission despite reperfusion, while the excitability and morphology of neurons recovered rapidly and more completely. Next, I adapted optogenetic motor mapping to investigate the changes of motor processing, and compared to the changes of sensory processing following the transient global ischemia. I found that both sensory and motor processing showed prolonged impairments despite of the recovery of neuronal excitability following reperfusion, presumably due to the unrestored synaptic transmission. Interestingly, motor processing recovered faster and more completely than sensory processing. My results suggest a uniform suppression of synaptic transmission, both in excitatory and inhibitory network, despite the rapid recovery of neuronal excitability and morphology, following a global ischemia and reperfusion. This prolonged suppression of synaptic transmission might impede the recovery of sensory and motor processing with differential severity. Besides, I extended tools for mesoscopic imaging using novel optogenetic sensors, including genetically encoded Ca2+ indicators - GCaMPs, and extracellular glutamate sensor - iGluSnFR. I found that iGluSnFR has fastest kinetics for reporting both sensory and spontaneous activity in the cortex, which can resolve temporal features of sensory processing that were not readily observed with GECIs. I suggest that iGluSnFR tools have potential utility in normal physiology, and neurologic pathologies in which abnormalities in glutamatergic signaling are implicated, such as stroke.

description: The emerging vapor pressure-driven osmosis (VPDO) membrane technology enables direct conversion of abundant low-temperature (<100 °C) heat resources to useful work. In this study, a theoretical model is established to understand mass and heat transfer of VPDO, and two hydrophobic nanoporous membranes, polypropylene (PP) and polytetrafluoroethylene (PTFE), of different chemistry and structural properties were evaluated. Although the PP membrane has a less effective transport pathway, the considerably larger pore size yields a much higher Knudsen diffusivity that results in consistently higher vapor fluxes across different temperature-pressure conditions. This finding provides strong evidence that mass transfer in VPDO is dominated by Knudsen diffusion. Additionally, we find that operation at higher pressurizations caused vapor flux decline that is attributed to the membrane morphological deformation. However, the PP membrane is less sensitive to the effects of compaction, underlining the importance of membrane mechanical robustness for VPDO. Lastly, the study shows that evaporative heat transfer is significantly greater than conductive losses and the PP membrane, with higher water fluxes, has better evaporation thermal efficiencies. This study provides fundamental understanding on the impacts of membrane properties on mass and heat transfer in VPDO, and highlights the centrality of vapor permeability and mechanical robustness in developing high-performance membranes.
Postcolonial citizenship : reconceiving authority and belonging in settler societies

Publisher: name: University of British Columbia

description: In Postcolonial Citizenship: Reconceiving Authority and Belonging in Settler Societies I argue that a key undertheorized barrier to the self-determination of Indigenous peoples in Canada is a conceptual one that effectively (and often incorrectly) transforms claims related to self-determination into claims for some form of differentiated citizenship within the Canadian state. I argue that this conceptual disconnect should be understood as a conflict between competing conceptions of citizenship and, in response, I have proposed an analytical framework (Chapter 2) that serves to highlight how community and authority stand in a recursive relationship with each other to comprise the referent for citizenship. Further, I have argued that in contexts of settler colonialism, the underlying settler colonial ideology functions to impose a colonial referent that subordinates any conception of citizenship to an underlying and undertheorized commitment to territoriality or the modern spatial strategy to control resources and people by controlling geographical area. As an undertheorized foundation for theories of citizenship, territoriality imposes relationships of domination—first between humans and land (including animals, rocks, rivers, trees, etc.) and subsequently between humans and their political authorities. Chapters 3 and 4 describe how the initial anthropocentric domination of land through the imposition of territorial boundaries undermines the emancipatory narratives of canonical (Hobbes, Locke, Rousseau) and contemporary (Taylor, Kymlicka, Tully) theories of citizenship. In Chapter 5, I argue that the domination that is inherent in territorial frameworks is especially poignant for Indigenous peoples who do not endorse the Western philosophical foundations that enable domination. In addition, I have sought to articulate an alternative referent by drawing on critical Indigenist thought in order to provide a clearer picture of the kinds Indigenist alternative conceptions of citizenship that are foreclosed by an imposition of territorial domination. I conclude in Chapter 6 by outlining a conception of postcolonial citizenship that emerges when an Indigenist view of citizenship like the one presented in Chapter 5 confronts settler colonialism and how this confrontation ought to inform strategies for reconciliation.

description: We theoretically investigate the spin-dependent transport for the system of an armchair-edge graphene nanoribbon (AGNR) between two ferromagnetic (FM) leads with arbitrary polarization directions at low temperatures, where a magnetic insulator is deposited on the AGNR to induce an exchange splitting between spin-up and -down carriers. By using the standard nonequilibrium Green's function (NGF) technique, it is demonstrated that, the spin-resolved transport property for the system depends sensitively on both the width of AGNR and the polarization strength of FM leads. The tunneling magnetoresistance (TMR) around zero bias voltage possesses a pronounced plateau structure for system with semiconducting 7-AGNR or metallic 8-AGNR in the absence of exchange splitting, but this plateau structure for 8-AGNR system is remarkably broader than that for 7-AGNR one. Interestingly, the increase of exchange splitting $Δ$ suppresses the amplitude of the structure for 7-AGNR system. However, the TMR is enhanced much for 8-AGNR system under the bias amplitude comparable to splitting strength. Further, the current-induced spin transfer torque (STT) for 7-AGNR system is systematically larger than that for 8-AGNR one. The findings here suggest the design of GNR-based spintronic devices by using a metallic AGNR, but it is more favorable to fabricate a current-controlled magnetic memory element by using a semiconducting AGNR.

description: We present an estimate of the black hole mass function (BHMF) of broad line quasars (BLQSOs) that self-consistently corrects for incompleteness and the statistical uncertainty in the mass estimates, based on a sample of 9886 quasars at 1 < z < 4.5 drawn from the Sloan Digital Sky Survey. We find evidence for `cosmic downsizing' of black holes in BLQSOs, where the peak in their number density shifts to higher redshift with increasing black hole mass. The cosmic mass density for black holes seen as BLQSOs peaks at z ~ 2. We estimate the completeness of the SDSS as a function of black hole mass and Eddington ratio, and find that at z > 1 it is highly incomplete at M_BH < 10^9 M_Sun and L / L_Edd < 0.5. We also estimate a lower limit on the lifetime of a single BLQSO phase and we place constraints on the maximum mass of a black hole in a BLQSO. Our estimated distribution of BLQSO Eddington ratios peaks at L / L_Edd ~ 0.05 and has a dispersion of ~ 0.4 dex, implying that most BLQSOs are not radiating at or near the Eddington limit; however the location of the peak is subject to considerable uncertainty. The steep increase in number density of BLQSOs toward lower Eddington ratios is expected if the BLQSO accretion rate monotonically decays with time. Furthermore, our estimated lifetime and Eddington ratio distributions imply that the majority of the most massive black holes spend a significant amount of time growing in an earlier obscured phase, a conclusion which is independent of the unknown obscured fraction. These results are consistent with models for self-regulated black hole growth, at least for massive systems at z > 1, where the BLQSO phase occurs at the end of a fueling event when black hole feedback unbinds the accreting gas, halting the accretion flow.

Outsider art : forty years out
Creators: name: Rainaldi, Linda
Publisher: name: University of British Columbia
Year: 2015

description: French artist Jean Dubuffet delivered an anti-cultural manifesto in the 1940s. He fought against the status quo in the art world and argued against the traditions of art history, where art is studied in the context of its historical development and where art standards are the result of cultural conditioning and the opinions of art critics. To illustrate his thesis, Dubuffet went on to create an art collection, which he called art brut, from artists who he believed were not influenced by culture or social norms. In 1972 Roger Cardinal, a British scholar, wrote a book about art brut, calling it outsider art. Many new definitions of outsider art subsequently evolved, particularly in the United States, and there has been little agreement on the definition of outsider art or the terminology coined to describe it. This thesis examines the American and European perspectives on outsider art and suggests the underlying biases, ideologies, and social factors that informed the definitions, such as the myths surrounding mental illness, movements towards social inclusion, and movements away from the marginalizing effect of labels. As outsider art gains more recognition in the art world, some defend its categorization as a separate genre of art while others challenge the need to keep it separate from mainstream art, and those reasons are explored. Finally, it is suggested that there may be little value in attaching labels to any genre of art because every definition of outsider art reflects the biases and personal logic of its author. Dialogue and debate are encouraged and suggestions for continuing research are outlined.

description: Recent glacier mass loss in Greenland has been attributed to encroaching warming waters, but knowledge of fjord bathymetry is required to investigate this mechanism. The bathymetry in many Greenland fjords is unmapped and difficult to measure. From 2010 to 2012, National Aeronautics and Space Administration’s Operation IceBridge collected a unique set of airborne gravity, magnetic, radar, and lidar data along the major outlet glaciers and fjords in Greenland. We applied a consistent technique using the IceBridge gravity data to create 90 bathymetric profiles along 54 Greenland fjords. We also used this technique to recover subice topography where warm or crevassed ice prevents the radar system from imaging the bed. Here we discuss our methodology, basic assumptions and error analysis. We present the new bathymetry data and discuss observations in six major regions of Greenland covered by IceBridge. The gravity models provide a total of 1950 line kilometers of bathymetry, 875 line kilometers of subice topography, and 12 new grounding line depths.
