description: This paper investigates the impacts of cotton marketing reforms on farm productivity, a key element for poverty alleviation, in rural Zambia. The reforms comprised the elimination of the Zambian cotton marketing board that was in place since 1977. Following liberalization, the sector adopted an outgrower scheme, whereby firms provided extension services to farmers and sold inputs on loans that were repaid at the time of harvest. There are two distinctive phases of the reforms: a failure of the outgrower scheme, and a subsequent period of success of the scheme. Our findings indicate that the reforms led to interesting dynamics in cotton farming. During the phase of failure, farmers were pushed back into subsistence and productivity in cotton declined. With the improvement of the outgrower scheme of later years, farmers devoted larger shares of land to cash crops, and farm productivity significantly increased.
Saturn's Icy Moon Rhea: a Prediction for Bulk Chemical Composition and Physical Structure at the Time of the Cassini Spacecraft First Flyby

description: I report a model for the formation of Saturn's family of mid-sized icy moons to coincide with the first flypast of Rhea by the Cassini Orbiter spacecraft on 26 November 2005. It is proposed that these moons had condensed from a concentric family of orbiting gas rings that were cast off some 4600 Myr ago by the contracting proto-Saturnian cloud. Numerical and structural models for Rhea are constructed on the basis of a computed bulk chemical mix of hydrated rock (mass fraction 0.385), H2O ice (0.395), and NH3 ice (0.220). The large proportion of NH3 in the ice mass inhibits the formation of the dense crystalline phase II of H2O ice at the satellite's centre. This may explain the absence of compressional features on the surface. The favoured model of Rhea has a chemically uniform interior and is very cold. The satellite is nearly isodense and the predicted value of the axial moment-of-inertia factor is C/MR^2 = 0.399 +/- 0.004. NH3 is unstable at Saturn's distance from the Sun, except near the polar regions of the satellite. Perhaps the Cassini Orbiter will discover indirect evidence for NH3 through the sublimative escape of this ice from the outer layers, especially near the equatorial zones. Wasting of NH3 would weaken the residual soil, so making the edges of craters soft and prone to landslides. It will be exciting to learn what Cassini discovers.

description: We explore the extent to which the huge race gap in wealth can be explained with properly constructed income and demographic variables. In some instances we explain the entire wealth gap with income and demographics provided that we estimate the wealth model on a sample of whites. However, we typically explain a much smaller fraction when we estimate the wealth model on a black sample. Using sibling comparisons to control for intergenerational transfers and the effects of adverse history, we find that differences in income and demographics are not likely to account for the lower explanatory power of the black wealth models. Our analysis of growth models of wealth suggests that differences in savings behavior and/or rates of return play an important role.

description: We carry out a two-dimensional study of temperature, entropy and pressure distributions in a nearly volume-limited subsample of REFLEX clusters at redshift 0.3, the REFLEX-DXL. We use the observations gained by XMM-Newton, which cover the central 1-2 x r500. We define the substructure in both entropy and pressure as a deviation from the mean profile of the sample. The non-parametric locally weighted regression suggests a broken power law approximation to the entropy profile with inner and outer slopes of 0.78 and 0.52, respectively, and a break at 0.5r500. The characterization of the pressure profile is more complex, requiring three power laws, with slopes -0.64 at r<0.3r500, -2.47 at r>0.5r500 and a slope of -1.50 in between. An analysis of the substructure in the pressure and entropy maps reveals somewhat larger fluctuations around the mean pressure profile compared to the entropy. Typically, pressure fluctuations are found on the 30% level, while the entropy fluctuations are at the 20% level (r.m.s.). We compare the cumulative distribution of the substructure level in the REFLEX-DXL sample with the results of numerical simulation and by means of KS test show that they are in agreement. A discussion of the origin of the substructure is provided on individual cluster basis.

description: We study the defect (or "signed area") distribution of toral Laplace eigenfunctions restricted to shrinking balls of radius above the Planck scale, in either random Gaussian scenario ("Arithmetic Random Waves"), or deterministic eigenfunctions averaged w.r.t. the spatial variable. In either scenario we exploit the associated symmetry of the eigenfunctions to show that the expectation (Gaussian or spatial) vanishes. Our principal results concern the high energy limit behaviour of the defect variance.

description: We have carried out a high angular resolution near-infrared imaging study of the fields of 6 quasars with 7 strong absorption line systems at z < 0.5, using the Hokupa'a adaptive optics system and the QUIRC near-infrared camera on the Gemini-North telescope. These absorption systems include 4 classical damped Lyman-alpha absorbers (DLAs), 2 sub-DLAs, and one Lyman-limit system. Images were obtained in the H or K' filters with FWHM between 0.2"-0.5" with the goal of detecting the absorbing galaxies and identifying their morphologies. Features are seen at projected separations of 0.5"-16.0" from the quasars and all of the fields show features at less than 2" separation. We find candidate absorbers in all of the seven systems. With the assumption that some of these are associated with the absorbers, the absorbers are low luminosity < 0.1 L*_H or L*_K; we do not find any large bright candidate absorbers in any of our fields. Some fields show compact features that are too faint for quantitative morphology, but could arise in dwarf galaxies.

Plotinus, the Islamic intellectual tradition and the metaphysics of nature
Creators: name: Hansen, Brian P.
Publisher: name: University of British Columbia
Year: 2009

description: Plotinus, the Islamic Intellectual Tradition and the Metaphysics of Nature examines the profound influence that the spiritual functions of nature as expressed by Plotinus (205-270 CE) exerted on certain developing philosophical and mystical currents in Islam during its first three centuries. In addition, this thesis demonstrates that Plotinus' metaphysics continues to live within contemporary Islamic intellectual circles, specifically in the work of a significant orthodox Islamic thinker— Seyyed Hossein Nasr, who, in allying himself and his religion with Plotinus' dynamic metaphysics, not only clarifies Islamic metaphysical doctrines, but also supplies a significant spiritual context for modern scientific inquiry into the physical world. The first chapter describes and assesses what Seyyed Hossein Nasr defines as the philosophia perennis, paying particular attention to the role of the Intellect, simultaneously a metaphysical principle and potential human spiritual experience that is central in Plotinus, mystically-based Islamic philosophy and Sufism. The second chapter gives a brief analytical summary of Plotinus' metaphysical worldview, underscoring his double emphasis on the Unity experienced via Intellectual vision and the 'metaphysical transparency' of the natural world. The third explores the significant details of Plotinus' metaphysics of nature in preparation for specific demonstrations, in the chapter following it, of how and why Islam embraced elements of Plotinian metaphysics. The fourth chapter appraises the impact that Plotinus' teaching on the beauty and metaphysical transparency of the sensible world had on certain intellectual currents in Islam. This is presented via an historical overview and an analysis of thematic correspondences between Plotinus' metaphysics and the orthodox Islamic worldview as articulated by Seyyed Hossein Nasr. Finally, the fifth chapter evaluates, along with Nasr, the potential for a new scientific paradigm of nature and suggests areas for possible future study. All five chapters support our views that the Intellect functions both as metaphysical bridge between Plotinus and Islam, that its awakened vision is central to the search for the Divine in both spiritual 'ways' and that the insights of an awakened Intellect could contribute to the development of a new, efficacious scientific paradigm for nature.
Undergraduate Programme Leadership and the Teaching Excellence Framework in Small Universities: A Case Study
Creators: name: Meeson, Graham V.
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: This research aimed to understand how undergraduate programme leaders at small universities understand their role. The Teaching Excellence Framework (TEF), a component of the United Kingdom’s (UK) 2017 Higher Education and Research Act was used as a focus. The TEF reinforced existing market-like behaviours within the sector by providing information supporting student decisions regarding where to study. This economic framing of university education was consistent with market principles predominating in the UK’s public sector since the late 20th century. Data for this study was collected during the winter and spring of 2017-2018, following the publication of the institutional TEF results (June 2017). Small universities are a distinctive type of university, mostly focussing on undergraduate teaching. Undergraduate degree courses are often led by some form of programme leader. The literature regarding this role highlights both its challenges, and its importance for programme effectiveness. The TEF represents a national policy intervention with potential impact upon the work of programme leaders. Nine semi-structured interviews were conducted with programme leaders working at five small universities. Weick’s (1995) view of sensemaking was employed to develop an analytical lens to assess the interviews’ content. This revealed that, although the participants possess a limited understanding of the TEF, they exhibit a willingness to incorporate the underpinning principles into their work. This contrasts with the articulation of their values, focussed on interpersonal and educational aspects of the work in the sector. In the absence of the universities concerned providing a clear understanding of the TEF, the participants often employ their previous professional identities and experiences to understand their programme leader role. The original contribution to knowledge of this research is an understanding of how programme leaders in small universities comprehend their role in relation to a national policy implementation associated with learning and teaching.

description: We report self- and air collisional broadening coefficients for the H₂O line at 7299.43 cm⁻¹ and corresponding temperature coefficients for a temperature range spanning 293–573 K. New laser spectroscopic setups specifically designed for this purpose have been developed and are described. The line parameters reported here are in good agreement with those values reported in the HITRAN 2020 database, but the uncertainties have been reduced by factors of about 4, 1.3 and 4.4 for the self-broadening coefficient, air broadening coefficient and the temperature exponent of air broadening, respectively. Further, we combined our measurement approach with metrological data quality objectives, addressing the traceability of the results to the international system of units (SI) and evaluated the uncertainties following the guide to the expression of uncertainty in measurement (GUM).

description: We have used the Advanced Camera for Surveys on board the Hubble Space Telescope to obtain deep photometry of the NGC 300 spiral galaxy in the Sculptor group. The results have been used to derive an accurate distance determination based on the Tip of the Red Giant Branch distance estimator. Both edge-detection and maximum likelihood methods have been applied, to derive a distance modulus (m-M)_0=26.30 +/- 0.03 +/- 0.12 for edge-detection, and (m-M)_0=26.36 +/- 0.02 +/- 0.12 for maximum likelihood. These results are fully consistent with the recent distance estimate derived from near-IR photometry of Cepheids variable stars in the context of the Araucaria project, (m-M)_0= 26.37 +/- 0.05 +/- 0.03.

description: Software test cases can be defined as a set of condition where a tester needs to test and determine that the System Under Test (SUT) satisfied with the expected result correctly. This paper discusses the optimization technique in generating cases automatically by using EpiT (Eclipse Plug-in Tool). EpiT is developed to optimize the generation of test cases from source code in order to reduce time used for conventional manually creating test cases. By using code smell functionality, EpiT helps to generate test cases automatically from Java programs by checking its line of code (LOC). The implementation of EpiT will also be presented based on several case studies conducted to show the optimization of the test cases generated. Based on the results presented, EpiT is proven to solve the problem for software tester to generate test case manually and check the optimization from the source code using code smell technique.

Energy and environmental benefits of alternative work arrangements
Creators: name: Hasan, Ajaz
Publisher: name: University of British Columbia
Year: 2009

description: The present rate of fossil fuel burning, the main source of commercial energy, is adversely impacting global climate. Present social and economic practices need to be examined to question their level of energy use and related greenhouse gas emission. Energy used to operate buildings and to transport people is a significant portion of the total energy consumption and reductions in these uses will be crucial to addressing the global issues. This thesis examines the potential for energy use reduction in the performance of office work through the use of Alternative Work Arrangements ("AWAs"). The analysis considers the operating energy of an office building, operating energy of alternative work locations and the transportation energy spent by employees in commuting from home to work. A brief synopsis of the present atmospheric, energy use and workplace trend is presented. The synthesis of these trends is used as a framework to evaluate the impact of AWAs. The work arrangements in the Burnaby Fraser Tax Services Office ('BFTSO'), Surrey, BC are used as a case study to analyze the operating and commuting energy spent by the employees working by different arrangements. Telework is found to be the most energy efficient work arrangement implemented at the BFTSO. Under optimum operating conditions, net energy saving per teleworker can be 34.06 GJ per annum. Net savings in greenhouse gas emission per teleworker can be 1950 kg per annum. For hoteling work arrangement, net energy savings per hoteling employee under optimum conditions can be 32 GJ per annum. Related savings in greenhouse gas emissions can be 1532 kg per annum. The proportion of total operating and total commuting energy for the BFTSO is almost equal. However, the greenhouse gas emission from total commuting energy is three times that from operating energy due to differences in carbon intensity of the fuel mix. Under optimum conditions the implementation of AWAs at the BFTSO can result in 36 percent saving in total operating energy and 43 percent saving in total commuting energy. The magnitude of the savings is location dependent due to differences in climate, fuel mix and transportation patterns. Alternative Work Arrangements have mixed social impact. It can improve the ability of employees to balance their personal and professional life. It can also lead to isolation that can adversely impact morale and work output. The participation rate in AWAs within organizations is currently low, less than 2 percent. However, the implementation of AWA is widespread with most organizations using some form of AWA. To increase the participation rate in AWAs, a comprehensive approach needs to be adopted, considering the professional, personal, economic and social impact of AWAs. Government intervention through supporting regulations and incentives can be a strong catalyst for increasing participation rates in AWAs.

description: The possibility of reconciliation between seemingly mutually exclusive properties in one system can not only lead to theoretical breakthroughs but also potential novel applications. The research on the coexistence of two purportedly contra-indicated properties, ferroelectricity/polarity and conductivity, proposed by Anderson and Blount over 50 years ago was recently revitalized by the discovery of the first unambiguous polar metal LiOsO3 and further fueled by the demonstration of the first switchable ferroelectric metal WTe2. In this review, we first discuss the reasons why the coexistence of ferroelectricity/polarity and conductivity have been deemed incompatible, followed by a review on the history of ferroelectric/polar metals. Secondly, we review the important milestones along with the corresponding mechanisms for the ferroelectric/polar metallic phases in these materials. Thirdly, we summarize the design approaches for ferroelectric/polar metals. Finally, we discuss the future prospects and potential applications of ferroelectric/polar metals.

description: Recent measurements of the Josephson critical current through LSCO/LCO/LSCO thin films showed an unusually large proximity effect. Using the Bogoliubov-de Gennes (BdG) equations for a tight binding Hamiltonian we describe the proximity effect in weak links between a superconductor with critical temperature $T_c$ and one with critical temperature $T_c$', where $T_c>T_c$'. The weak link (N') is therefore a superconductor above its own critical temperature and the superconducting regions are considered to have either s-wave or d-wave symmetry. We note that the proximity effect is enhanced due to the presence of superconducting correlations in the weak link. The dc Josephson current is calculated, and we obtain a non-zero value for temperatures greater than $T_c$' for sizes of the weak links that can be almost an order of magnitude greater than the conventional coherence length. Considering pockets of superconductivity in the N' layer, we show that this can lead to an even larger effect on the Josephson critical current by effectively shortening the weak link.

The presence of the Wilson line ensuring color gauge invariance of the correlator induces structures that were not given explicitly in the existing literature. In particular, the general form of the transverse momentum dependent correlator entering various hard scattering processes is derived. In this case two new time-reversal odd parton distributions appear at the twist-3 level.

For Max Planck it marks the failure of a long-term research program, in which he tried to understand the 2nd law of thermodynamics deterministically in terms of mechanics and electrodynamics. For Albert Einstein it meant a refutation of his scientific credo. I describe parts of the early stages of this most remarkable development, up to Einstein's light-quantum hypotheis and its unfavourable reception by most other physicists.

description: Engineering atomic-scale defects is crucial for realizing wafer-scale, single-crystalline transition metal dichalcogenide monolayers for electronic devices. However, connecting atomic-scale defects to larger morphologies poses a significant challenge. Using electron microscopy and atomistic simulations, we provide insights into WS2 crystal growth mechanisms, providing a direct link between synthetic conditions and the microstructure. Dark-field TEM imaging of coalesced monolayer WS2 films illuminates defect arrays that atomic-resolution STEM imaging identifies as translational grain boundaries. Imaging reveals the films to have nearly a single orientation with imperfectly stitched domains. Through atomic-resolution imaging and ReaxFF reactive force field-based molecular dynamics simulations, we observe two types of translational mismatch and discuss their atomic structures and origin. Our results indicate that the mismatch results from relatively fast growth rates. Through statistical analysis of >1300 facets, we demonstrate that the macrostructural features are constructed from nanometer-scale building blocks, describing the system across sub-Ångstrom to multi-micrometer length scales.

description: Cystic fibrosis (CF) is a life-limiting, inherited disorder caused by a faulty gene, which affects many parts of the body, most predominantly the lungs and gut. Currently no cure exists for CF and treatment regimens are intensive and time consuming. CF results in substantial psychosocial sequelae.The salience of disclosure of an individual’s CF diagnosis has increased as the average life expectancy has extended. The integrative review aimed to synthesis evidence exploring the experiences of individuals who disclose CF to others. Five electronic databases were searched and eight studies met the inclusion criteria. Findings indicated that disclosure of CF is a complex process, with the potential to elicit positive support and development, whilst, conversely, being associated with high anxiety and possible negative effects. As such, individuals with CF undergo a multifaceted decision-making process before disclosing. Findings were discussed in relation to relevant literature and theories, clinical implications and future research.CF is predominantly diagnosed during infancy. However, a small proportion of individuals, who present clinically and socially differently, are diagnosed in adulthood. Therefore, the empirical study aimed to explore the experiences of individuals who received a diagnosis of CF as adults, including psychological impact and support around diagnosis. Semi-structured interviews were conducted with six participants and analysed using Interpretative Phenomenological Analysis. Four super-ordinate themes, comprised of 12 sub-themes, emerged from the data. The super-ordinate themes were: ‘Inexplicable and failing’; ‘The blow of diagnosis’; ‘Processing journey’ and ‘Managing others’. Themes were discussed in relation to relevant literature and theory, with recommendations made for clinical practice and future research.

description: Geographic Information Systems (GIS) are becoming increasingly important to virtually all of the natural and social sciences. Applied economists will find that GIS can make valuable contributions to many of the problems with which they are concerned. Moreover, a great deal of the science behind GIS technology would benefit from the contributions of applied economists. This paper presents some initial suggestions for the ways in which GIS may be important to economics and the GIS related issues concerning which applied economists could provide useful insights.

description: Supra-arcade downflows (SADs) are dark, teardrop-shaped features descending upon flare arcades. They are thought to be the results of magnetic reconnection, but the detailed formation mechanism of SADs and their relationship to flare energy release are still unclear. In this work, we explore the thermodynamical properties of SADs in the 2011 October 22 limb flare using the observations of the Solar Dynamics Observatory/Atmospheric Imaging Assembly and an improved Differential Emission Measure (DEM) technique. Different heating events around SADs are identified and the propagation speeds of plasma heating are calculated. The first heating event starts with the increase of the emission measure at temperatures higher than 5 MK, about 2.8 minutes before the arrival of the first studied SAD. Its propagation speed is about 140 km/s, a little faster than the speed of the SAD. However, the other two events have fast propagation speeds more than 700 km/s. We suspect that the first heating event can be explained by adiabatic compression, but the others may have different causes. Besides, we observed that SADs can push away their surrounding spikes. The formation of SADs is further explained on the basis of patchy and bursty magnetic reconnection that reconnection outflows may push away surrounding plasma and leave dark lanes behind them. The reliability of the DEM results, heating and cooling mechanisms, and other SAD explanations are discussed.

description: Natural resource-based economic development efforts are becoming increasingly popular. Interest focuses on industries that export from a state, in order to expand the state and local economic base. The Northern and Central Appalachian states should be ideally positioned to benefit from forest-based resources, as they have extensive hardwood forests, a favorable growth-to-drain ratio, and easily accessible national and international markets. This paper examines the export levels of several hardwood product industries and uses tobit analysis to examine establishment and location characteristics related to higher export levels.

description: We compare the statistical properties of giant gravitationally lensed arcs produced in matched simulated and observed cluster samples. The observed sample consists of 10 X-ray selected clusters at redshifts z ~ 0.2 imaged with HST by Smith et al. The simulated dataset is produced by lensing the Hubble Deep Field, which serves as a background source image, with 150 realizations (different projections and shifts) of five simulated z = 0.2 clusters from a LambdaCDM N-body simulation. The real and simulated clusters have similar masses, the real photometric redshift is used for each background source, and all the observational effects influencing arc detection in the real dataset, including light from cluster galaxies, are simulated in the artificial dataset. We develop, and apply to both datasets, an objective automatic arc-finding algorithm. We find consistent arc statistics in the real and in the simulated sample, with an average of ~ 1 detected giant (length to width ratio >= 10) arc per cluster and ~ 0.2 giant luminous (R<22.3 mag) arc per cluster. Thus, taking into account a realistic source population and observational effects, the clusters predicted by LambdaCDM have the same arc-production efficiency as the observed clusters. If, as suggested by other studies, there is a discrepancy between the predicted and the observed total number of arcs on the sky, it must be the result of differences between the redshift dependent cluster mass functions, and not due to differences in the lensing efficiency of the most massive clusters.

description: Road accidents are estimated to be the ninth leading cause of death across all age groups globally. 1.25 million people die annually from road accidents and Africa has the highest rate of road fatalities [1]. Research shows that three out of five road accidents are caused by driver-related behavioral factors [2]. Self-driving technology has the potential of saving lives lost to these preventable road accidents. Africa accounts for the majority of road fatalities and as such would benefit immensely from this technology. However, financial constraints prevent viable experimentation and research into self-driving technology in Africa. This paper describes the design of RollE, an affordable modular autonomous vehicle development platform. It is capable of driving via remote control for data collection and also capable of autonomous driving using a convolutional neural network. This system is aimed at providing students and researchers with an affordable autonomous vehicle to develop and test self-driving car technology.

description: There are now several experimental collaborations that have seen evidence for a narrow state in the mass spectrum of the ($nK^+$) system. Two of these experiments, from the LEPS collaboration in Japan and the CLAS collaboration in the USA, are described briefly. Both use similar photoproduction reactions with a $K^+K^-$ pair in the final state. In addition, data from the CLAS collaboration for the $γp \to K_s K^+ n$ reaction are presented for the first time, which has no prominant peak in the ($nK^+$) mass spectrum when the $K_s$ angle is limited to forward angles.

description: Crop yields which determine farm income deficiency payments have been frozen at 1981-1985 levels since 1986. Data from a longitudinal survey of Ohio farm operators are analyzed to evaluate whether updating payment yields will differentially affect farm operators. Results of the analysis imply that farm operators who operate larger farms, live in counties with higher yields, and have higher fertilizer and pesticide expenses per acre of corn will benefit more. In addition, low (high) existing payment yields are understated (overstated) relative to updated payment yields.

description: Accessing the point-spread function (PSF) of a complex optical system is important for a variety of imaging applications. However, placing an invasive point source is often impractical, and estimating it blindly with multiple frames is slow and requires a complex non-linear optimization. Here, we introduce a simple single-shot method to non-invasively recover the accurate PSF of an isoplanatic imaging system, in the context of multiple light scattering. Our approach is based on the reconstruction of any unknown sparse hidden object using the autocorrelation imaging technique, followed by a deconvolution with a blur kernel derived from the statistics of a speckle pattern. A deconvolution on the camera image then retrieves the accurate PSF of the system, enabling further imaging applications. We demonstrate numerically and experimentally the effectiveness of this approach compared to previous deconvolution techniques.

description: A map of 100 degrees on a side extracted from Gaia DR2 and centred on Alpha Persei reveals two distinct structures | the Alpha Persei star cluster and a conspicuous stellar stream, as widely documented in recent literature. In this work we employ DBSCAN to assess individual stars' membership and attempt at separating stars belonging to the cluster and to the stream from the general field. In turn, we characterize the stream and investigate its relation with the cluster. The stream population turned out to be significantly older (5+/-1Gyr) than the cluster, and to be positioned ~90 pc away from the cluster, in its background. The stream exhibits a sizeable thickness of ~180 pc in the direction of the line of view. Finally, the stream harbours a prominent population of white dwarf stars. We estimated an upper limit of the stream mass of ~6000 solar masses?. The stream would therefore be the leftover of a relatively massive old cluster. The surface density map of the Alpha Persei evidences the presence of tidal tails. While it is tempting to ascribe them to the interaction with the disrupting old star cluster, we prefer to believe, conservatively, they are of Galactic origin.
