description: Images of the steady-state luminescence of passivated GaAs self-standing films under excitation by a tightly-focussed laser are analyzed as a function of light excitation power. While unipolar diffusion of photoelectrons is dominant at very low light excitation power, an increased power results in a decrease of the diffusion constant near the center of the image due to the onset of ambipolar diffusion. The results are in agreement with a numerical solution of the diffusion equations and with a physical analysis of the luminescence intensity at the centre of the image, which permits the determination of the ambipolar diffusion constant as a function of electron concentration.

description: Extreme weather disasters (EWDs) can jeopardize domestic food supply and disrupt commodity markets. However, historical impacts on European crop production associated with droughts, heatwaves, floods, and cold waves are not well understood—especially in view of potential adverse trends in the severity of impacts due to climate change. Here, we combine observational agricultural data (FAOSTAT) with an extreme weather disaster database (EM-DAT) between 1961 and 2018 to evaluate European crop production responses to EWD. Using a compositing approach (superposed epoch analysis), we show that historical droughts and heatwaves reduced European cereal yields on average by 9% and 7.3%, respectively, associated with a wide range of responses (inter-quartile range +2% to −23%; +2% to −17%). Non-cereal yields declined by 3.8% and 3.1% during the same set of events. Cold waves led to cereal and non-cereal yield declines by 1.3% and 2.6%, while flood impacts were marginal and not statistically significant. Production losses are largely driven by yield declines, with no significant changes in harvested area. While all four event frequencies significantly increased over time, the severity of heatwave and drought impacts on crop production roughly tripled over the last 50 years, from −2.2% (1964–1990) to −7.3% (1991–2015). Drought-related cereal production losses are shown to intensify by more than 3% yr−1. Both the trend in frequency and severity can possibly be explained by changes in the vulnerability of the exposed system and underlying climate change impacts.
Insights into philanthropy An investigation into motivations for UK charitable giving
Creators: name: Maple, Peter
Publisher: name: London South Bank University
Year: 2021

description: Almost £23 billion is given by individuals voluntarily to UK charities every year. This is hugely important for those organisations as it represents 43% of their total income and this percentage is increasing (Hornung et al., 2019). This thesis investigates why people decide to give money to charity, in order to develop an improved understanding of their underlying motivations and the dynamics of what prompts or triggers a gift. It will be of value anyone interested in changing the world by sustaining and enhancing individual donations of money to charity. A literature review reveals knowledge gaps about why people develop into givers and what prompts them to change existing charitable allegiances or make new commitments. This research uses an interpretive, pragmatic approach to analyse the data from 46 in-depth interviews with philanthropists to gain improved insights into the underlying values, drivers and motivational triggers for charitable giving. There is evidence that many individuals acquire a giving habit at a very early age and that significant life experiences also impact giving behaviour. However, motivations are fluid and people change charity allegiances throughout their lives. Furthermore, these changes continue into the charitable will making process that half of UK philanthropists may undertake. The findings show that relationships often develop between givers and charity fundraisers. An important conclusion emerging from this evidence is that the nature of that relationship between the fundraiser and the giver may be very significant in determining giving motivations and behaviour. A further conclusion is that giving motivations can be far more fluid than most theories allow, and a new, dynamic theory of giving is proposed. This research has sampling and analytical limitations but nevertheless, offers new insights about the prompts that trigger movements in giving motivations. These are important factors for fundraising charities to use more effectively. The thesis provides an original contribution to the understanding of what motivates people to donate money and presents recommendations for practitioners, policy development and further research.

Numerical solutions to altimetry-gravimetry boundary value problems in coastal regions

description: This thesis presents novel solutions of altimetry-gravimetry boundary value problems (AGBVPs) with compatibility (smoothness) conditions along the coastline for geoid determination. After an analysis of the state of the art for AGBVPs it was found that a lot of work has already been done in terms of theoretical problem formulation and solution investigation of AGBVPs. The conditions under which the solutions of different AGBVPs exist and are unique have been provided. It has been shown that without additional compatibility conditions along the coastline a solution with higher level of regularity does not exist. This was the starting point of this work and, after three preliminary experiments, it was found that the effect of smoothness along the coast line is significant for cm-geoid determination. Further theoretical investigations by the author resulted in the following achievements and contributions to local and regional determination of the geoid. The theory of spherical pseudo-differential operators (PDOs), spherical wavelets and spherical harmonics was combined for local and regional geoid determination in coastal areas. Using the theory of PDOs, it has been proven that the fixed AGBVP II has a unique solution and different methods applied to solve this problem yield the same solution. It has been shown that the compatibility conditions given by Svensson (1988) are equivalent to the condition that the data and their first and second order gradients coincide with each other along the coastline. It has been proven that PDOs are uniformly Lipschitz α in this case, they can be combined with wavelets that are locally Lipschitz α to increase the regularity (smoothness) of the solution along the coastline. A modified algorithm for reconstruction of a signal using wavelet modulus maxima points is suggested to detect and to smooth existing discrepancies and irregularities along the coastline. Any kind of functionals of disturbing potential is presented in a discrete form, which allows spherical PDOs and wavelets to be applied numerically; even the compatibility conditions are expressed in an explicit form in discrete form as a sum of two functionals described above. Final numerical solution with spherical H­Shannon wavelets was proposed and conclusions are drawn about its advantages from an application point of view. Finally, as a result of the proposed procedure a smooth transition of the geoid from land to sea can be achieved, which will result in an improved geoid model in coastal areas.
Universal dynamics of the entropy of work distribution in spinor Bose-Einstein condensates

description: Driving a quantum many-body system across the quantum phase transition (QPT) in the finite time has been concerned in different branches of physics to explore various fundamental questions. Here, we analyze how the underlying QPT affects the work distribution $P(W)$, when the control parameter of a ferromagnetic spinor Bose-Einstein condensates is tuned through the critical point in the finite time. We show that the work distribution undergoes a dramatic change with increasing the driving time $τ$. To capture the characteristics of the work distribution, we analyze the entropy of $P(W)$ and find three different regions in the evolution of entropy as a function of $τ$. Specifically, the entropy is insensitive to the driving time in the region of very short $τ$, while it exhibits a universal power-law decay in the region with intermediate value of $τ$. In particular, the power-law scaling of the entropy is according with the well-known Kibble-Zurek mechanism. For the region with large $τ$, the validity of the adiabatic perturbation theory leads to the entropy decay as $τ^{-2}\lnτ$. Our results verify the usefulness of the entropy of the work distribution for understanding the critical dynamics and provide an alternative way to experimentally study nonequilibrium properties in quantum many-body systems.

description: Climate science provides strong evidence of the necessity of limiting global warming to 1.5 °C, in line with the Paris Climate Agreement. The IPCC 1.5 °C special report (SR1.5) presents 414 emissions scenarios modelled for the report, of which around 50 are classified as '1.5 °C scenarios', with no or low temperature overshoot. These emission scenarios differ in their reliance on individual mitigation levers, including reduction of global energy demand, decarbonisation of energy production, development of land-management systems, and the pace and scale of deploying carbon dioxide removal (CDR) technologies. The reliance of 1.5 °C scenarios on these levers needs to be critically assessed in light of the potentials of the relevant technologies and roll-out plans. We use a set of five parameters to bundle and characterise the mitigation levers employed in the SR1.5 1.5 °C scenarios. For each of these levers, we draw on the literature to define 'medium' and 'high' upper bounds that delineate between their 'reasonable', 'challenging' and 'speculative' use by mid century. We do not find any 1.5 °C scenarios that stay within all medium upper bounds on the five mitigation levers. Scenarios most frequently 'over use' CDR with geological storage as a mitigation lever, whilst reductions of energy demand and carbon intensity of energy production are 'over used' less frequently. If we allow mitigation levers to be employed up to our high upper bounds, we are left with 22 of the SR1.5 1.5 °C scenarios with no or low overshoot. The scenarios that fulfil these criteria are characterised by greater coverage of the available mitigation levers than those scenarios that exceed at least one of the high upper bounds. When excluding the two scenarios that exceed the SR1.5 carbon budget for limiting global warming to 1.5 °C, this subset of 1.5 °C scenarios shows a range of 15–22 Gt CO2 (16–22 Gt CO2 interquartile range) for emissions in 2030. For the year of reaching net zero CO2 emissions the range is 2039–2061 (2049–2057 interquartile range).

description: The nature of public policy has changed with the advent of globalization as governments have attempted to increase efficiency to compete in a global economy. Public institutions, such as public education, have been greatly impacted by these changes, suffering layoffs, salary cuts and reduced funding, all of which have coincided with increased standardization and a lower public opinion of public education. Educational Partnerships (EPs) have emerged as unique opportunities to bridge gaps created by a changing policy environment which benefit multiple stakeholders in education. This MDP explores the development of EPs at the secondary level in public education. The study uses a case study approach and a results-based management framework to evaluate whether EPs are viable solutions for some of the problems facing public education. The analysis focuses on major trends, such as globalization and market-led policy reforms, from which several themes are identified: the changing role of government in the provision of public services, a new role for the private sector in corporate social responsibility, and internal changes in the public education domain, all of which have influenced the formation of EPs. Complicating the EP process are principles of equity and integration upon which public education is based. The case studies explore the impact of EPs on equity in learning, on the integration of diverse student populations, and on efficiency of service delivery. The findings from the literature review and the case studies are combined to make recommendations for nurturing and improving EPs in public education.

Delimiting democracy?: media representations of volunteerism
Creators: name: Grosenick, Georgina C.
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 110-123
description: The objective of this thesis is to explore how one of the more powerful cultural discourses in society, the mass media, represents volunteerism. Volunteerism is a practice that is important to society and an essential component of democratic culture. An empirical study was conducted using content and critical discourse analysis to examine a sample of media reports about volunteerism from two national and two regional newspapers. An emphasis was placed on comparing media discourse surrounding service volunteerism and advocacy volunteerism. The study found that the media reports examined did not represent the full spectrum and role of volunteerism's contribution to society and that service and advocacy volunteerism were framed differently. This pattern of discourse has the potential to influence the sustainability of the voluntary sector and in tum, delimit our democracy.

description: Direct near field electrospinning is used to produce very long helical polystyrene microfibers in water. The pitch length of helices can be controlled by changing the applied voltage, allowing to produce both micro springs and microchannels. Using a novel high frequency variable voltage electrospinning method we found the helix formation speed and compared the experimental buckling frequency to theoretical expressions for viscous and elastic buckling. Finally we showed that the newmethod can be used to produce new periodic micro and nano structures.

description: In previous warm-up chemical models of the low-mass star-forming region L1527, we investigated the evolution of carbon-chain unsaturated hydrocarbon species when the envelope temperature is slightly elevated to $T\approx 30$ K. These models demonstrated that enhanced abundances of such species can be explained by gas-phase ion-molecule chemistry following the partial sublimation of methane from grain surfaces. We also concluded that the abundances of hydrocarbon radicals such as the C$_{\rm n}$H family should be further enhanced as the temperatures increase to higher values, but this conclusion stood in contrast with the lack of unambiguous detection of these species toward hot core and corino sources. Meanwhile, observational surveys have identified C$_2$H, C$_4$H, CH$_3$CCH, and CH$_3$OH toward hot corinos (especially IRAS 16293-2422) as well as towards L1527, with lower abundances for the carbon chain radicals and higher abundances for the other two species toward the hot corinos. In addition, the {\it Herschel Space Telescope} has detected the bare linear chain C$_3$ in 50 K material surrounding young high-mass stellar objects. To understand these new results, we revisit previous warm-up models with an augmented gas-grain network that incorporated reactions from a gas-phase network that was constructed for use with increased temperature up to 800 K. Some of the newly adopted reactions between carbon-chain species and abundant H$_2$ possess chemical activation energy barriers. The revised model results now better reproduce the observed abundances of unsaturated carbon chains under hot-corino (100 K) conditions and make predictions for the abundances of bare carbon chains in the 50 K regions observed by Herschel HIFI.

Food choices in the southern Peruvian Andes

description: Material, socio-cultural, and personal factors affect food choices. The purpose of this study was to investigate both food consumption and some variables impacting food choices of mothers and children in two Andean communities. Recent works in the Andes have documented an increasing reliance on purchased foods. Using dietary recalls, free lists, Q-sorts, and observations, this study was conducted over four months with ten women and ten children in Yanahuara (pop. 3050) and Urubamba (pop.11 500) in southern Peru. The Yanahuara sample were financially restricted to more local foods, and prefered these for taste and health reasons. The Urubamba sample could afford more commercial foods, often chosen for convenience, and tended to value them more. The results support integrative approaches of food choice and are largely consistent with data on consumption and dietary change from other Andean regions. The guinea pig's high prestige value, however, appears specific to the Peruvian highlands.

description: We prove that any complete surface with constant mean curvature in a homogeneous space E(κ,τ) which is transversal to the vertical Killing vector field is, in fact, a vertical graph. As a consequence we get that any orientable, parabolic, complete, immersed surface with constant mean curvature H in E(κ,τ) (different from a horizontal slice in S^2xR) is either a vertical cylinder or a vertical graph (in both cases, it must be 4H^2+κ\leq0).

Measurement of the Differential Cross Section for Isolated Prompt Photon Production in pp Collisions at 7 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A measurement of the differential cross section for the inclusive production of isolated prompt photons in proton-proton collisions at a centre-of-mass energy of 7 TeV is presented. The data sample corresponds to an integrated luminosity of 36 inverse picobarns recorded by the CMS detector at the LHC. The measurement covers the pseudorapidity range |eta|<2.5 and the transverse energy range 25 < ET < 400 GeV, corresponding to the kinematic region 0.007 < xT < 0.114. Photon candidates are identified with two complementary methods, one based on photon conversions in the silicon tracker and the other on isolated energy deposits in the electromagnetic calorimeter. The measured cross section is presented as a function of ET in four pseudorapidity regions. The next-to-leading-order perturbative QCD calculations are consistent with the measured cross section.

description: The estimation of differential energy loss for charged particles in tracker detectors is studied. The robust truncated mean method can be generalized to the linear combination of the energy deposit measurements. The optimized weights in case of arithmetic and geometric means are obtained using a detailed simulation. The results show better particle separation power for both semiconductor and gaseous detectors.

Type Ia supernovae and the ^{12}C+^{12}C reaction rate

description: The experimental determination of the cross-section of the ^{12}C+^{12}C reaction has never been made at astrophysically relevant energies (E<2 MeV). The profusion of resonances throughout the measured energy range has led to speculation that there is an unknown resonance at E\sim1.5 MeV possibly as strong as the one measured for the resonance at 2.14 MeV. We study the implications that such a resonance would have for the physics of SNIa, paying special attention to the phases that go from the crossing of the ignition curve to the dynamical event. We use one-dimensional hydrostatic and hydrodynamic codes to follow the evolution of accreting white dwarfs until they grow close to the Chandrasekhar mass and explode as SNIa. In our simulations, we account for a low-energy resonance by exploring the parameter space allowed by experimental data. A change in the ^{12}C+^{12}C rate similar to the one explored here would have profound consequences for the physical conditions in the SNIa explosion, namely the central density, neutronization, thermal profile, mass of the convective core, location of the runaway hot spot, or time elapsed since crossing the ignition curve. For instance, with the largest resonance strength we use, the time elapsed since crossing the ignition curve to the supernova event is shorter by a factor ten than for models using the standard rate of ^{12}C+^{12}C, and the runaway temperature is reduced from \sim8.14\times10^{8} K to \sim4.26\times10^{8} K. On the other hand, a resonance at 1.5 MeV, with a strength ten thousand times smaller than the one measured at 2.14 MeV, but with an α/p yield ratio substantially different from 1 would have a sizeable impact on the degree of neutronization of matter during carbon simmering. We conclude that a robust understanding of the links between SNIa properties and their progenitors will not be attained until the ^{12}C+^{12}C reaction rate is measured at energies \sim1.5 MeV.

description: Two methods for network-based carrier phase real-time kinematic positioning are proposed and evaluated in this thesis. These two methods are a correction-based, and a tightly coupled, approach. Novel algorithm enhancements are proposed for the correction-based approach, while the tightly coupled approach, which integrates reference station and user data in a single solution, is an innovative extension of a method previously developed. Each stage of the correction-based approach requires coherent information. The covariance function provides the stochastic basis of the estimation process and is used in each stage of this approach. A novel method for implementing an adaptive covariance function that is used subsequently is proposed. The adaptive qualities are shown to effectively track changing temporal and spatial error conditions, especially atmospheric conditions, throughout the data sets. The derivation of a least-squares prediction based approach, more specifically a least-squares collocation approach, is performed. This includes the value and variance-covariance of the estimated corrections. Further derivation shows the ef­fect of these elements on the reduced rover measurements. This approach reduces the differential measurement errors and improves position accuracy relative to the single baseline approach. The tightly coupled approach is an extension of a multiple mobile user positioning approach, whereby inter-receiver position differences are connected to all reference stations and user(s) in the same estimation filter. This could also be considered an extension of the correction-based approach where the position of one or more of the reference stations is uncertain or unknown. This approach is also shown to improve position accuracy relative to the single baseline and correction-based approach. These two methods are compared and analysed. In general, both methods per­form better than the single reference station approach however, the tightly coupled approach performs slightly better than the correction-based approach in terms of position accuracy, based on the data sets used for the evaluation of the two methods.

Labour and delivery nurses' perceptions of barriers to assessing for pregnancy abuse

description: Bibliography: p. 88-101
description: A psychometrically sound tool, Barriers to Abuse Assessment Tool (BAA I), was developed that identifies labour and delivery nurses' (LDN) perceptions of barriers to assessment. The primary purpose of this study was to explore relationships between LDNs characteristics and perceptions of barriers with their abuse assessment practices. The researcher found that not all of the factors identified as potential barriers to abuse assessment were associated with LDNs abuse assessment practices. However, the researcher revealed important factors that influence LDN abuse assessment. Fear of partner retaliation, ethical, personal, and knowledge barriers are statistically associated with LDNs' frequency of abuse assessment. LDNs recognize that abuse assessment is in the domain of their practice. However, the same LDNs are selective when assessing for abuse. LDNs need to be empowered to assess for abuse. In order for LDNs to be empowered, changes are needed in education, policy, and health care institutions to overcome these barriers.

description: Entanglement plays a crucial role in proposals for quantum metrology, yet demonstrating quantum enhancement in sensing with sustained spin entanglement remains a challenging endeavor. Here, we combine optical pumping and continuous quantum nondemolition measurements to achieve a sustained spin squeezed state with $\bm{4 \times 10^{10}}$ hot atoms. A metrologically relevant steady state squeezing of $\bm{-3.23 \pm 0.24}$ dB using prediction and retrodiction is maintained for about one day. We employ the system to track different types of continuous time-fluctuating magnetic fields, where we construct deep learning models to decode the measurement records from the optical signals. Quantum enhancement due to the steady spin squeezing is verified in our atomic magnetometer. These results represent important progress towards applying long-lived quantum entanglement resources in realistic settings.
Using generation to improve memory accuracy in a false recognition pradigm

Publisher: name: University of Calgary

description: Bibliography: p. 51-59
description: Using the Deese-Roediger-McDermott paradigm, recollection of distinctive information about cognitive operations was shown to improve recognition accuracy. Requiring participants to generate (vs. read) each list word by solving an anagram substantially decreased false recognition of non-presented critical lure words. In addition, correct recognition increased when generation occurred at both study and test--even if different anagram cues were presented at test-suggesting that reinstating cognitive operations at test can facilitate correct recognition. When participants generated half the lists and read the other half at study, false recognition decreased for both generated and read lists, relative to a group who read all list words at study. This finding suggests that generation induced participants to adopt a distinctiveness heuristic at test, whereby they took the absence of memory for generation as evidence for a word's nonoccurrence at study, and is less consistent with an impoverished relational encoding account that attributes false recognition to impaired encoding of relations between list words.
Ranges, restrictions, partial maps, and fibrations

description: Bibliography: p. 224-226
description: In this thesis, we study range restriction categories and their properties. Range restriction categories with split restriction idempotents are shown to be equivalent to the partial map categories of ℳ-stable factorization systems. The notions of a restriction fibration, a range restriction fibration, a stable meet semilattice fibration, and a range stable meet semilattice fibration are introduced and it is shown that (range) stable meet semilattice fibrations provide a bridge between the category of (range) restriction categories and the category of categories and that (range) restric­tion fibrations are the same as (range) restriction categories so that these fibrations provide a useful setting for studying (range) restriction categories. Finally, we con­struct the free range restriction structures over directed graphs using deterministic trees.

description: One way to select a preferred frame from gravitational radiation is via the principal axes of < L L>, an average of the action of rotation group generators on the Weyl tensor at asymptotic infinity. In this paper we evaluate this time-domain average for a quasicircular binary using approximate (post-Newtonian) waveforms. For nonprecessing unequal-mass binaries, we show the dominant eigenvector of this tensor lies along the orbital angular momentum. For precessing binaries, this frame is not generally aligned with either the orbital or total angular momentum, working to leading order in the spins. The difference between these two quantities grows with time, as the binary approaches the end of the inspiral and both precession and higher harmonics become more significant.
