description: Social VR has demonstrated new potential for relationships, but also novel forms of immersive and embodied harms. This will soon be followed by cross-reality experiences that support social interaction—and potential harm—across virtual and physical reality, as exemplified by emerging VR dating applications. This paper presents a participatory design study of VR dating with 16 stakeholders identifying as women and/or LGBTQIA+ to reflect on how safety can be designed for in cross-reality—not as a reaction to harm that is already occurring, but as a proactive initiative to address fears that may limit technology adoption and inclusion. Findings elucidate three types of cross-reality harms that participants identified as most related to a sense of safety: physical harm as retaliation for romantic rejection across realities, unintentional physical harm through assuming consent to similar behaviors across realities, as well as risks associated with misinformed decisions to meet in the physical world. Design directions to instill a sense of cross-reality safety involved augmented consent exchange capabilities and intervention of virtually and physically co-located bystanders.

description: Organic-inorganic hybrid perovskites (OIHPs) have attracted extensive research interest as a promising candidate for efficient and inexpensive solar cells. Transmission electron microscopy characterizations that can benefit the fundamental understanding and the degradation mechanism are widely used for these materials. However, their sensitivity to the electron beam illumination and hence structural instabilities usually prevent us from obtaining the intrinsic information or even lead to significant artifacts. Here, we systematacially investigate the structural degradation behaviors under different experimental factors to reveal the optimized conditions for TEM characterizations of OIHPs by using low-dose electron diffraction and imaging techniques. We find that a low temperature does not slow down the beam damage but instead induces a rapid amorphization for OIHPs. Moreover, a less severe damage is observed at a higher accelerating voltage. The beam-sensitivity is found to be facet-dependent that a (100) exposed MAPbI3 surface is more stable than (001) surface. With these guidance, we successfully acquire the atomic structure of pristine MAPbI3 and identify the characterization window that is very narrow. These findings are helpful to guide future electron microscopy characterization of these beam-sensitive materials, which are also useful for finding strategies to improve the stability and the performance of the perovskite solar cells.

title: Economics essays on rice seed security and sovereignty in Guinea Bissau
Creators: name: Coruche, Maria Piedade de Avillez Luz
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2018

description: This thesis aims to examine the status of seed security and seed sovereignty among female lowland rice farmers in Guinea Bissau. It draws from different, while complementary strands of the literature, investigating seed systems. One focusing on functional aspects of farmers’ seed systems, such as availability, access and varietal suitability, while the other stems from seed sovereignty movement which looks at seed systems from a rights perspective. This research objective is to contribute to this literature by providing new insights on seed security measures, quantitative evidence of the effects of seed security on food production and on how farmers, in context of limited statehood can protect their rights under a multi-level governance system “pushing” their rights’ in different directions. Chapter 1 provides an introduction on the issues surrounding seed systems, seed security and seed sovereignty in developing countries, the motivation and the research objectives. Chapter 2 develops a comprehensive measure of seed security with the objective to capture in a single measure all the different dimensions behind seed security. Chapter 3 builds on findings of the previous chapter, by employing the seed security index and other seed security measures, to estimate the determinants of seed security and the effect of seed security on food production. Chapter 4 puts the former research in a broader context. Using qualitative evidence in the sector, this last chapter looks at seed sovereignty from the perspective of a fragile state in the context of international and national governance regimes. Overall this thesis has found that availability and social access are currently the key dimensions driving seed security status among lowland rice farmers. This is a result of high levels of poverty and a residual formal seed market, where farmers resort predominantly on their own seed and seed in their social networks, to produce rice, their major staple crop. Area owned and household labour are found to be the key determinants of seed security while results also suggest that seed security has a positive effect on rice production. This research has also found that external forces accruing from global and regional seed governance regimes are not currently undermining nor reinforcing seed sovereignty rights that lowland farmers’ seem to be enjoying. However, the uneven influence between regimes might change the status quo towards the erosion of farmers’ rights, with consequences for their livelihoods and agro-biodiversity.

description: The massive cluster of galaxies Abell 2219 (z = 0.228) was observed at 14.3 $μ$m with the Infrared Space Observatory and results were published by Barvainis et al. (1999). These observations have been reanalyzed using a method specifically designed for the detection of faint sources that had been applied to other clusters. Five new sources were detected and the resulting cumulative total of ten sources all have optical counterparts. The mid-infrared sources are identified with three cluster members, three foreground galaxies, an Extremely Red Object, a star and two galaxies of unknown redshift. The spectral energy distributions (SEDs) of the galaxies are fit with models from a selection, using the program GRASIL. Best-fits are obtained, in general, with models of galaxies with ongoing star formation. For three cluster members the infrared luminosities derived from the model SEDs are between ~5.7x10^10 Lsun and 1.4x10^11 Lsun, corresponding to infrared star formation rates between 10 and 24 Msun yr^-1. The two cluster galaxies that have optical classifications are in the Butcher-Oemler region of the color-magnitude diagramme. The three foreground galaxies have infrared luminosities between 1.5x10^10 Lsun and 9.4x10^10 Lsun yielding infrared star formation rates between 3 and 16 Msun yr^-1. Two of the foreground galaxies are located in two foreground galaxy enhancements (Boschin et al. 2004). Including Abell 2219, six distant clusters of galaxies have been mapped with ISOCAM and luminous infrared galaxies (LIRGs) have been found in three of them. The presence of LIRGs in Abell 2219 strengthens the association between luminous infrared galaxies in clusters and recent or ongoing cluster merger activity.

Upper limb bone health : cadaveric, imaging and clinical studies with special emphasis on peripheral quantitative computed tomography
Creators: name: Ashe, Maureen Celeste
Publisher: name: University of British Columbia
Year: 2009

description: Introduction: Osteoporotic fractures are a major health care problem. A radial fracture is an important risk factor for osteoporosis that should initiate the assessment of bone health. Purpose: 1) To validate pQCT measures of bone in aged cadaveric radii. 2) To examine side-side differences in radial bone variables after disuse. 3) To test a novel intervention for secondary prevention of osteoporosis after an index radial fracture. Methods: Study Design: Part 1: Parts 1A and 1B are descriptive cadaveric studies. Part 2: Cross-sectional observational studies of bone response to disuse; Part 3: Part 3A is a 6-month intervention of secondary prevention of osteoporosis following a fragility fracture. Part 3B uses a questionnaire to ascertain barriers to investigation after fracture. Participants: Part 1: Cadaveric specimens from women (73 to 88 years) for Parts 1A and 1B. Part 2A: Women (52-87 years) who sustained a distal radius fracture and Part 2B: women and men (52 to 79 years) who had suffered a stroke. Part 3A: Women and men (50-90 years) with a fragility fracture; and Part 3B: physicians in British Columbia. Results: Part 1: With different pQCT acquisition-analysis protocols, total bone area varied by 3-34%; cortical area varied by 3-30% and total content by 6-45% from a criterion standard. Total bone content of the distal radius explained between 74 and 81% of bone strength. Part 2: There was a significant decrease in bone strength in participants who had upper limb disuse because of stroke or fracture. Part 3: A patient and physician intervention improved bone health investigation rate by a factor of 3.1 times (RR) after fragility fracture. BC doctors reported few barriers to investigating osteoporosis. Summary: Peripheral QCT acquisition and analysis protocols significantly influenced outcome variables. Patients do not have "normal" bone strength after fracture or stroke. In particular, there is an increased risk for non-dominant radial fractures to have lower bone strength and be associated with poorer limb function, compared with a dominant radial fracture. Physicians report no barriers to investigation after a fragility radial fracture and a systematic intervention may best address secondary prevention of osteoporosis.
A Low Solar Oxygen Abundance from the First Overtone OH Lines

description: An extremely high-resolution (> 10^5) high-S/N (> 10^3) solar spectrum has been used to measure 15 very weak first overtone (Delta v = 2) infrared OH lines, resulting in a low solar abundance of A(O) ~ 8.6 when MARCS, 3D, and spatially and temporally averaged 3D model atmospheres are used. A higher abundance is obtained with Kurucz (A(O) ~ 8.7) and Holweger & Muller (A(O) ~ 8.8) model atmospheres. The low solar oxygen abundance obtained in this work is in good agreement with a recent 3D analysis of [OI], OI, OH fundamental (Delta v = 1) vibration-rotation and OH pure rotation lines (Asplund et al. 2004). The present result brings further support for a low solar metallicity, and although using a low solar abundance with OPAL opacities ruins the agreement between the calculated and the helioseismic measurement of the depth of the solar convection zone, recent results from the OP project show that the opacities near the base of the solar convection zone are larger than previously thought, bringing further confidence for a low solar oxygen abundance.

description: Periodic pulse train stimulation is generically used to study the function of the nervous system and to counteract disease-related neuronal activity, e.g., collective periodic neuronal oscillations. The efficient control of neuronal dynamics without compromising brain tissue is key to research and clinical purposes. We here adapt the minimum charge control theory, recently developed for a single neuron, to a network of interacting neurons exhibiting collective periodic oscillations. We present a general expression for the optimal waveform, which provides an entrainment of a neural network to the stimulation frequency with a minimum absolute value of the stimulating current. As in the case of a single neuron, the optimal waveform is of bang-off-bang type, but its parameters are now determined by the parameters of the effective phase response curve of the entire network, rather than of a single neuron. The theoretical results are confirmed by three specific examples: two small-scale networks of FitzHugh-Nagumo neurons with synaptic and electric couplings, as well as a large-scale network of synaptically coupled quadratic integrate-and-fire neurons.

description: This study develops a structural market model for the econometric analysis of buyers’ market power in the Ukrainian meat processing industry, because there is some evidence that suggests that meat processors may excise market power in the agricultural market of slaughtered livestock. The estimation results did not produce any evidence suggesting the existence of buyers’ market power. Contrary to many other NEIO-studies, we extended the market structure market model by the three subsequent models. Using endogenously determined values for market power parameter, we found that meat processors concerning the buyers’ market for slaughtered livestock behave consistently with Cournot conjectures.

description: A conceptual marketing-finance framework is proposed which links channel contracting in agriculture and the use of financial facilitating services (e.g., financial derivatives) to (shareholder) value creation. The framework complements existing literature by explicitly including channel contract relationships as market-based assets that can be managed to reduce cash flow volatility and hence increase shareholder value. We show how financial facilitating services (e.g., derivatives) can be used to complement the cash flows components of channel contract relationships thereby further reducing the risk adjusted cost of capital and improving shareholder value. In a field study of producers, wholesalers, and processors, in the potato and meat industry the framework shows how shareholder value can be enhanced by using financial facilitating services, such as derivatives, to complement marketing channel relationships. Moreover, this study shows how producers and managers from agribusiness companies can use such financial services as conflict-solving tools in case of incongruent contract preferences between channel members.
title: Organising for disruptive innovation: everyday entrepreneuring efforts at an incumbent technology company
Creators: name: Whitelaw, Lisa
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2020

description: In an age of disruptions leading organisations need to embrace new ways of working to maintain their competitive advantage. Yet how to do so within the constraints of established business practices remains unclear. In a longitudinal ethnographic case study I investigated in real-time over a period of three years an incumbent organisation’s efforts to organise for disruptive innovation from an organisation-creation perspective. Using a processual, practice-based, engaged scholarship approach, I followed the situated development of six potentially disruptive innovation projects on-the-ground as they unfolded at Thales UK, a leading multinational technology company. As a full member of Thales UK Research, Technology and Innovation (RTI), I observed and contributed directly to the company’s efforts to organise for disruptive innovation from an insider account. I show how the company’s efforts to organise for disruptive innovation interrupted organisational members’ collectively held practical understandings of their work, illuminate how the established organisational arrangement is used in everyday performative efforts to organise for disruptive innovation, and illustrate how the entrepreneurial development of disruptive opportunities over time is both shaped by and impacts on the organisational context they develop within. In a confessional tale I share my experience of studying and contributing to the company’s efforts to organise for disruptive innovation in real-time as a toolkit for other researchers to engage in similar scholar-practitioner collaborative research arrangements. I draw together my findings in a process model of organising for disruptive innovation in an incumbent organisation. I contribute to the disruptive innovation literature a contextually situated understanding of the process of organising for disruptive innovation in an incumbent organisation. In empirically operationalising organisation-creation theory using a processual, practice-based, engaged scholarship approach, I advance research methods for studying innovation processes in real-time and infuse practical understanding and know-how into a mainly theory-driven body of organisation-creation research.

description: Based on their theoretical predictions, Kliauga, de Gorter, and Just (2008) and de Gorter, Drabik, and Just (2010) argue that the United States and the European Union establish the world ethanol and biodiesel prices, respectively. We test these theories using cointegration analysis and the Vector Error Correction (VEC) model. Weekly price series are analyzed for the major global biofuel producers (European Union, United States, and Brazil) for the period 2002 – 2010. Polices in the United States and Brazil appear to play an equal role in determining ethanol prices in other countries, thus only partially confirming the theoretical predictions. For biodiesel, our results demonstrate that the EU mandate impacts the world biodiesel price and thus they confirm the European Union’s price leadership established in theory.

description: Heterogeneity, i.e., the notion that individuals respond differently to economic stimuli, can have profound consequences for the interpretation of behavior and the formulation of agricultural policy. This paper compares and evaluates three grouping techniques that can be used to account for heterogeneity in financial behavior. Two are well established: company-type grouping and cluster analysis. A third, the generalized mixture regression model, has recently been developed and is worth considering as market participants are grouped such that their response to the determinants of economic behavior is similar. We evaluate the grouping methods in a hedging framework by assessing their ability to reflect relationships consistent with theory. The empirical findings show that the economic relationships are more consistent with theory within the groups identified by the mixture model, and suggest that researchers interested in identifying segments of the population in which participants behave in a similar manner may consider using of mixture model in the presence of heterogeneity in financial behavior.

description: Because original high-quality non-market valuation studies can be expensive, perhaps prohibitively so, benefits transfer (BT) approaches are often used for valuing, e.g., the outputs of multifunctional agriculture. Here we focus on the use of BT functions, a preferred method, and address an under-appreciated problem – variable selection uncertainty – and demonstrate a conceptually superior method of resolving it. We show that the standard method of value-function BT, using the full estimated model, may generate BT values that are too sensitive to insignificant variables, whereas models reduced by backward elimination of insignificant variables pay no attention to insignificant variables that may in fact have some influence on values. Rather than searching for the best single model for BT, Bayesian model averaging (BMA) is attentive to all of the variables that are a priori relevant, but uses posterior model probabilities to give systematically lower weight to less significant variables. We estimate a full value model for wetlands in the US, and then calculate BT values from the full model, a reduced model, and by BMA. Variable selection uncertainty is exemplified by regional variables for wetland location. Predicted values from the full model are quite sensitive to region; reduced models pay no attention to regional variables; and the BMA predictions are attentive to region but give it relatively low weight. However, the suite of insignificant RHS variables, taken together, have non-trivial influence on BT values. BMA predicted values, like values from reduced models, have much narrower confidence intervals than values calculated from the full model.
Epitaxial growth dynamics in gallium arsenide
Creators: name: Ballestad, Anders
Publisher: name: University of British Columbia
Year: 2009

description: The problem of a complete theory describing the far-from-equilibrium statistical mechanics of epitaxial crystal growth remains unsolved. Besides its academic importance, this problem is also interesting from the point of view of device manufacturing. In order to improve on the quality and performance of lateral nanostructures at the lengthscales required by today's technology, a better understanding of the physical mechanisms at play during epitaxial growth and their influence on the evolution of the large-scale morphology is required. In this thesis, we present a study of the morphological evolution of GaAs (001) during molecular beam epitaxy by experimental investigation, theoretical considerations and computational modeling. Experimental observations show that initially rough substrates smooth during growth and annealing towards a steady-state interface roughness, as dictated by kinetic roughening theory. This smoothing indicates that there is no need for a destabilizing step-edge barrier in this material system. In fact, generic surface growth models display a much better agreement with experiments when a weak, negative barrier is used. We also observe that surface features grow laterally, as well as vertically during epitaxy. A growth equation that models smoothing combined with lateral growth is the nonlinear, stochastic Kardar-Parisi-Zhang (KPZ) equation. Simulation fits match the experimentally observed surface morphologies quite well, but we argue that this agreement is coincidental and possibly a result of limited dynamic range in our experimental measurements. In light of these findings, we proceed by developing a coupled growth equations (CGE) model that describes the full morphological evolution of both flat and patterned starting surfaces. The resulting fundamental model consists of two coupled, spatially dependent rate equations that describe the interaction between diffusing adatoms and the surface through physical processes such as adatom diffusion, deposition, and incorporation and detachment at step edges. In the low slope, small amplitude limit, the CGE model reduces to a nonlinear growth equation similar to the KPZ equation. From this, the apparent applicability of the KPZ equation to surface shape evolution is explained. The CGE model is based on fundamental physical processes, and can therefore explain the un derlying physics, as well as describe macroscopic pattern evolution during growth.

description: An accurate and efficient numerical approximation of the multivariate normal (MVN) distribution function is necessary for obtaining maximum likelihood estimates for models involving the MVN distribution. Numerical integration through simulation (Monte Carlo) or number-theoretic (quasi–Monte Carlo) techniques is one way to accomplish this task. One popular simulation technique is the Geweke–Hajivassiliou–Keane MVN simulator. This paper reviews this technique and introduces a Mata function that implements it. It also computes analytical first-order derivatives of the simulated probability with respect to the variables and the variance–covariance parameters.

description: We prove existence results that give information about the space of minimal immersions of 2-tori into $ S ^ 3 $. More specifically, we show that \begin{enumerate} \item For every positive integer $ n $, there are countably many real $n $-dimensional families of minimally immersed 2-tori in $ S ^ 3 $. Every linearly full minimal immersion $ T ^ 2\to S ^ 3 $ belongs to exactly one of these families. \item Let $ \mathcal A $ be the space of rectangular 2-tori. There is a countable dense subset $\mathcal B $ of $\mathcal A $ such that every torus in $\mathcal B$ can be minimally immersed into $ S ^ 3 $. \end{enumerate} The main content of this manuscript lies in finding minimal immersions that satisfy {\bf periodicity conditions} and hence obtaining maps of tori, rather than simply immersions of the plane. We make use of a correspondence, established by Hitchin, between minimal tori in $S^3$ and algebraic curve data.

The Exact Geometry of a Kerr-Taub-NUT Solution of String Theory
Creators: name: Svendsen, Harald G.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this paper we study a solution of heterotic string theory corresponding to a rotating Kerr-Taub-NUT spacetime. It has an exact CFT description as a heterotic coset model, and a Lagrangian formulation as a gauged WZNW model. It is a generalisation of a recently discussed stringy Taub-NUT solution, and is interesting as another laboratory for studying the fate of closed timelike curves and cosmological singularities in string theory. We extend the computation of the exact metric and dilaton to this rotating case, and then discuss some properties of the metric, with particular emphasis on the curvature singularities.

title: The behavioural nature of safety voice: advancing concepts and measures to enable the prevention of harm
Creators: name: Noort, Mark Christiaan
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2020

description: Background: The concept of ‘safety voice’ captures the extent to which individuals speak-up about safety. The behaviour is deemed important for preventing accidents, yet interventions are needed because people often fail to speak-up (‘safety silence’), thus contributing to harmful outcomes across safety-critical domains. However, the concept remains disintegrated and grounded in limited evidence and methodologies. Thus, the utility of ‘safety voice’ for safety management remains unclear, prohibiting effective interventions. This thesis therefore aims to evaluate how the behavioural nature of safety voice may be optimally conceptualised, assessed and intervened on. Approach: Four articles presented a systematic literature review (n = 48 publications), twelve experimental studies (ntotal = 1,222) and an analysis of Cockpit Voice Recorder (CVR) transcripts across 172 aviation accidents (1962-2018; n = 14,128 conversational turns). Article 1 synthesised evidence from across theoretical domains. Article 2 presented the first experimental paradigm for safety voice (‘Walking the Plank’) to address nine methodological challenges. Article 3 observed safety silence in the laboratory to establish and conceptualise how the behaviour manifests in relationship to safety voice and interventions. Article 4 captured safety voice during real-life safety accidents, and investigated how risk, safety listening, power distance and CRM training impact on safety voice. Findings: Safety voice is a distinct concept that is highly ecological and situated, and that is important for understanding how safety voice contributes to accidents. A methodological reliance on self-reports and post-hoc methodologies was identified and addressed through the Walking the Plank paradigm. Safety silence, identifiable through assessing safety concerns, was scalable based on the degree of safety voice speech, with interventions uniquely impacting on five safety themes and hazard stages. Safety voice was found to occur frequently during real accidents, with the developed Threat Mitigation Model underscoring that safety concerns, safety voice and safety listening all contribute to preventing harm.
Minkowski space in $f(T)$ gravity

description: The full set of solutions of $f(T)$ gravity with the Minkowski metric is considered in this note. At the 4-th order in perturbations around the trivial tetrad solution, a new mode is found explicitly. Its presence signals a strong coupling problem that transcends the Minkowski background and also suggests the pathological nature of cosmological solutions.

description: This paper discusses the advantages of Halton sequences over pseudorandom uniform numbers when using simulation to approximate integrals numerically. We describe two types of sequences and give Mata examples. Finally, we document the Mata function halton(), currently in release 9.1 of Stata, which computes both a Halton sequence and its Hammersley variant. Options to use these point sets are available in the Stata 9 program asmprobit, a multinomial-probit estimator, and in the Stata 9.1 Mata function ghk(), the Geweke–Hajivassiliou–Keane multivariate-normal simulator.

description: The aim of this study was to investigate the effect of date supplement and iron plus physical activity on anemic female students. This study includes 40 anemic female students, from the new valley university; they were divided into four equal groups ten in each group; 1st group ingested “date” plus exercise, 2nd group ingested date without exercise, 3rd group supplemented with iron salts with exercise, 4th group supplemented with iron salts without exercise, pre/post-test VO2max, pulse rate, Hb, iron, ferritin and O2 were determined. 5 ml venous blood was drawn from all participants for the pre/post variables. Dose of date sheet was (10 gm) twice daily, and dose of iron salts was one capsule (5mg) daily. Results: Results indicated that date supplement, and iron together with exercise affect positively the anemic female students. Conclusion: black dates and iron with or without hulls, are effective, safe and cheap supplements for improving hemoglobin and restoring iron stores to correct iron deficiency.
Rethinking the externality issue for dryland salinity in Western Australia

description: Dryland salinity has been conceived of as a problem involving massive off‐site impacts and therefore requiring coordinated action to ensure that land managers reduce those off‐site impacts. In economic terms, salinity is seen as a problem of market failure due to externalities, including external costs from one farmer to another and from the farm sector to the non‐farm sector. In this article, we argue that, at least in Western Australia (WA), externalities are much less important as a cause of market failure than has been widely believed. If all externalities from salinity in WA were to be internalised, the impact on farm management would be small.

description: In this paper, we suggest a Stata routine for multinomial logit models with unobserved heterogeneity using maximum simulated likelihood based on Halton sequences. The purpose of this paper is twofold. First, we describe the technical implementation of the estimation routine and discuss its properties. Further, we compare our estimation routine with the Stata program gllamm, which solves integration by using Gauss–Hermite quadrature or adaptive quadrature. For the analysis, we draw on multilevel data about schooling. Our empirical findings show that the estimation techniques lead to approximately the same estimation results. The advantage of simulation over Gauss–Hermite quadrature is a marked reduction in computational time for integrals with higher dimensions. Adaptive quadrature leads to more stable results relative to the other integration methods. However, simulation is more time efficient. We find that maximum simulated likelihood leads to estimation results with reasonable accuracy in roughly half the time required when using adaptive quadrature.
