title: A Novel Framework for Assessing Unpaved Road Condition for Asset Management Using Satellite Imagery
Creators: name: Workman, Robin
Publisher: name: The Open University
Year: 2024

description: Unpaved roads play a crucial role in Low and Middle-Income Countries (LMIC), with poor road conditions restricting mobility and severely affecting socio-economic development. Road condition is crucial to planning and prioritising maintenance, but Local Road Authorities (LRAs) struggle to collect this data using conventional means. A gap analysis showed that optical satellite imagery is not currently used to provide condition information on unpaved roads, confirmed by a review of stakeholder requirements.

This research aims to determine how optical satellite imagery can provide information useful for road asset management sustainably and cost-effectively. It explores the feasibility of measuring unpaved road condition in LMICs using satellite earth observation and how the results can benefit LRAs. A novel framework for unpaved road condition assessment using satellite imagery is proposed to support the implementation of this research in LRAs. 

Trials were conducted in Tanzania using 83 roads, totalling 131.7 km. Conditions were predicted using pixel variation, and the results were compared to a ground-truth audit. Machine Learning was employed to explore automation and test lower resolutions with the aim of reducing imagery costs.

Using pixel variation, overall accuracies in predicting condition of up to 79.8% were achieved, with individual accuracy for bad-condition roads reaching up to 87.3%. Machine Learning accuracy results exceeded those of pixel variation, and tests on lower-resolution imagery showed the potential to reduce capital costs by up to 70%. 

The framework was developed to measure the condition of unpaved networks rapidly, objectively, and reliably. The framework can accommodate different strategies and data requirements, allowing LRAs to define how to use the data most effectively for asset management and maintenance prioritisation. Automated road condition assessment using satellite imagery would benefit LRAs by avoiding the barriers of conventional visual surveys and enabling them to transition towards a more modern asset management approach

description: We determine exact and analytic solutions of the gravitational field equations in Einstein-aether scalar model field with a Bianchi I background space. In particular, we consider nonlinear interactions of the scalar field with the aether field. For the model under consideration we can write the field equations by using the minisuperspace description. The point-like Lagrangian of the field equations depends on three unknown functions. We derive conservation laws for the field equations for specific forms of the unknown functions such that the field equations are Liouville integrable. Furthermore, we study the evolution of the field equations and the evolution of the anisotropies by determining the equilibrium points and analyzing their stability.

description: A general method is known to exist for studying Abelian and non-Abelian gauge theories, as well as Euclidean quantum gravity, at one-loop level on manifolds with boundary. In the latter case, boundary conditions on metric perturbations h can be chosen to be completely invariant under infinitesimal diffeomorphisms, to preserve the invariance group of the theory and BRST symmetry. In the de Donder gauge, however, the resulting boundary-value problem for the Laplace type operator acting on h is known to be self-adjoint but not strongly elliptic. The latter is a technical condition ensuring that a unique smooth solution of the boundary-value problem exists, which implies, in turn, that the global heat-kernel asymptotics yielding one-loop divergences and one-loop effective action actually exists. The present paper shows that, on the Euclidean four-ball, only the scalar part of perturbative modes for quantum gravity are affected by the lack of strong ellipticity. Further evidence for lack of strong ellipticity, from an analytic point of view, is therefore obtained. Interestingly, three sectors of the scalar-perturbation problem remain elliptic, while lack of strong ellipticity is confined to the remaining fourth sector. The integral representation of the resulting zeta-function asymptotics is also obtained; this remains regular at the origin by virtue of a spectral identity here obtained for the first time.

description: Micronutrient malnutrition is a serious problem in many developing countries. Recently, agricultural technologies have been discussed as a complement to other intervention programs. Plant breeding, targeted at developing staple foods with higher contents of essential vitamins and trace minerals, could benefit the poor in particular. Yet, the economic repercussions of such innovations are still unclear. Because traditional models of technology assessment are inappropriate to capture the specific ramifications, we suggest a health economics approach. Herein, micronutrient malnutrition is understood as a phenomenon that causes health costs through diseases and premature deaths. Details of the methodology are discussed within an ex ante study of Golden Rice in the Philippines. This technology promises to reduce vitamin A deficiency among the local population. Although it will not completely eliminate the problem, the expected benefits are sizeable. Depending on the underlying assumptions, internal rates of return on research investments range between 66 % and 133 %. This confirms that micronutrientdense staple crops can be an efficient way to reduce deficiency problems among the poor. However, due to uncertainty with respect to certain parameters, the numerical results should be interpreted as preliminary.

description: The ergodic hypothesis is examined for energetically open fluid systems represented by the barotropic Navier--Stokes equations with general inflow/outflow boundary conditions. We show that any globally bounded trajectory generates a stationary statistical solution, which is interpreted as a stochastic process with continuous trajectories supported by the family of weak solutions of the problem. The abstract Birkhoff--Khinchin theorem is applied to obtain convergence (in expectation and a.s.) of ergodic averages for any bounded Borel measurable function of state variables associated to any stationary solution. Finally, we show that validity of the ergodic hypothesis is determined by the behavior of entire solutions (i.e. a solution defined for any $t\in R$). In particular, the ergodic averages converge for any trajectory provided its $ω-$limit set in the trajectory space supports a unique (in law) stationary solution.

description: We present FUSE spectroscopy of SBS 0335-052, the second most metal-deficient blue compact dwarf (BCD) galaxy known (log O/H = -4.70). In addition to the H I Lyman series, we detect C II, N I, N II, O I, Si II, Ar I and Fe II absorption lines, mainly arising from the extended H I envelope in which SBS 0335-052 is embedded. No H2 absorption lines are seen. The absence of diffuse H2 implies that the warm H2 detected through infrared emission must be very clumpy and associated with the star-forming regions.The clumps should be denser than ~ 1000 cm^-3 and hotter than ~ 1000 K and account for > 5% of the total H I mass. Although SBS 0335-052 is a probable young galaxy, its neutral gas is not pristine. The metallicity of its neutral gas is similar to that of its ionized gas and is equal log O/H ~ -5. This metallicity is comparable to those found in the H I envelopes of four other BCDs with ionized gas metallicities spanning the wide range from log O/H = -4.8 to log O/H = -3.8, and in Ly-alpha absorbers, fueling the speculation that there may have been previous enrichment of the primordial neutral gas to a common metallicity level of log O/H ~ -5, possibly by Population III stars.

description: We introduce a contact law for the normal force generated between two contacting, elastically anisotropic bodies of arbitrary geometry. The only requirement is that their surfaces be smooth and frictionless. This anisotropic contact law is obtained from a simplification of the exact solution to the continuum elasticity problem and takes the familiar form of Hertz' contact law, with the only difference being the orientation-dependence of the material-specific contact modulus. The contact law is remarkably accurate when compared with the exact solution, for a wide range of materials and surface geometries. We describe a computationally efficient implementation of the contact law into a discrete element method code, taking advantage of the precomputation of the contact modulus over all possible orientations. Finally, we showcase two application examples based on real materials where elastic anisotropy of the particles induces noticeable effects on macroscopic behavior. Notably, the second example demonstrates the ability to engineer tunable vibrational band gaps in a one-dimensional granular crystal by mere rotation of the constituent spherical particles.

The social construction of competence and "incompetence" : problematics of hospital nursing work in the era of restructuring
Creators: name: Jamieson, Anne Marie
Publisher: name: University of British Columbia
Year: 2009

description: This is an institutional ethnography of front-line nurses and their work in hospitals in Vancouver and the Lower Mainland during the turmoil and change of health care restructuring. "Restructuring", then, is a contextual theme overshadowing the working lives of the nurses in this study. Another contextual theme is job segregation on the basis of gender and racialized ethnicity, seen when comparing the demographic compositions of nursing working groups on different levels of care (for example, more nurses from formerly colonized countries work in lower prestige areas like extended care). The intensification of nursing work, routinization, and an increasing division between conceptual and physical tasks have characterized hospital nursing work in the last decade. Nurses' anxiety about being "competent" in this new environment sometimes culminates in dysfunctional processes of negotiating "competent/incompetent" identities. This process (identified in the study as "anxious competence" and "projection of incompetence on the other"), is parallel to the phenomenon of "targeting" or workplace bullying at other worksites, and is usually directed by a few nurses toward an individual nurse who is new to the floor or who is somehow "different". This kind of targeting demarcates for some nurses the boundaries between what is competence and what is incompetence, and helps to maintain the reputation and prestige of their working group as "high functioning". Nurses have developed tactics of solidarity and resistance to targeting and negative effects of restructuring. The conceptual framework is informed by social constructionism, labour process theory, and feminist critical social theory. Fieldwork consisted of participant observation on three floors (corresponding to critical, acute, and extended levels of care) for one year in two hospitals in the Lower Mainland; and interviews with 25 front-line nurses and four nursing managers. Suggested policy changes could improve the working and interactional environments of nurses.

description: Agent-based modeling offers the technical opportunity to spatially integrate biophysical and socio-economic model components, thereby capturing the interactions between agricultural and environmental policy measures, land use decisions and ecological processes. Development paths in the use of resources can be calculated with the help of computer stimulations which determine the range of possible farm adjustments and policy interventions. Through coupling with global modeling systems, scenario analyses can be run to investigate the impacts of global change on land and water resources at regional and local level. This article gives an overview of agent-based modeling applied to the study of land use dynamics and policy options. It outlines an agricultural research project on agent-based, integrated modeling and concludes with a list of open questions.

description: It has been shown that the quantum state of the graviton field outside a black hole horizon carries information about the internal state of the hole. We explain how this allows unitary evaporation: the final radiation state is a complex superposition which depends linearly on the initial black hole state. Under time reversal, the radiation state evolves back to the original black hole quantum state. Formulations of the information paradox on a fixed semiclassical geometry describe only a small subset of the evaporation Hilbert space, and do not exclude overall unitarity.

description: Policy engagement is key to promoting quality physical education yet it has been identified as a ‘grand challenge’ for Health and/or Physical Education (H/PE) internationally. All H/PE professionals, including teacher educators, have a collective responsibility to engage with policy but existing research tells us little about how H/PE teacher educators (H/PETEs) understand and engage with policy. It is important to examine H/PETEs conceptualisations of policy for a few reasons, not least because teacher educators play a crucial role in supporting future generations of teachers who themselves will need to engage with policy as a core feature of their professional lives. Drawing on figurational sociology, and the concept of assemblage, this paper offers insights into the nature and development – or sociogenesis – of teacher educators’ conceptualisations of policy. The data shared in this paper was generated through semi-structured interviews with 12 H/PETE from 7 countries. Inductive-deductive analysis – drawing largely on figurational concepts such as interdependence, power, habitus and sociogenesis – revealed that H/PETEs conceptualised policy as: (i) informing intended action and change; (ii) a way to govern practice; (iii) imposition and possibility. In terms of how these conceptualisations came to be, key features of the H/PETE figuration that were identified as influential include: (i) interdependence with human and non-human elements; (ii) balances of power and (iii) social and individual habitus. It is concluded that capitalising on these elements through professional learning, for example, could support H/PETEs in engaging with policy in productive and meaningful ways. Given that engaging with policy is viewed as a collective responsibility of H/PETEs, and many – if not all – of the H/PETEs felt they needed support in this regard, this should be a key focus for the field.
Electron pairing in the Hubbard model as a result of on-site repulsion fluctuations

description: We focus our quantitative analysis on the stability of the insulator state in the Hubbard model at a half-filling. Taking into account large-scale fluctuations (with a long relaxation time) of the on-site Coulomb repulsion, we consider the possibility of realizing a stabile state which is characterized by pairing for electrons. The pairing mechanism is as follows: due to fluctuations of on-site repulsion of electrons, holes, as excited states, are formed electron pairs. The bare values of on-site Coulomb repulsion and its fluctuations, for which the states with electron pairing are stable, are calculated. The proposed pairing mechanism is to some extent similar to the formation of a localized moment in the Wolf model. The calculations were performed for the chain, as well as square and cubic lattices.

Untangling critical thinking in educational cyberspace
Creators: name: Ronaldson, Sharon Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: This study was methodologically situated within two cycles of insider action research and informed by the blending of the philosophical underpinnings of the interpretive and the praxis paradigms. It was conducted by one nurse-educator-researcher exploring the perspectives of eleven undergraduate student nurses, who engaged with "Nursing Journeys: Virtual Reflective Centre", a researcher-developed virtual, simulation instrument designed to promote critical thinking, while enrolled in a first-year nursing course in a college in British Columbia over a 12- week semester. The study participants kept a reflective journal for the duration of the study and interviews were conducted at the end of the semester. While interviews and journal excerpts were the primary sources of data, participant-observation, field notes and online dialogue transcripts were also used as data collection techniques. The analytic strategy chosen for this study was grounded theory. This study also traced a self-reflective journey of practice as research in an attempt to develop a greater understanding of the teaching and learning process in educational cyberspace. The findings of the study suggested that participants were able to articulate their definition of critical thinking and use this definition to work through the case narratives while role-playing the various virtual characters. The study participants were also able to recognize that they were only beginning to understand critical thinking and that it was not necessarily learned and actualized in a linear, individual fashion. The findings of the study also suggested the facilitation of critical thinking was contingent on a pattern of a way of knowing: Cyber-textual Mediated Knowing and several other factors: time, trust, facilitation, reflection, purposeful decision making in design. Although NJVRC may have properties that have the potential to promote critical thinking, its cognitive dimension was significantly more developed than the affective dispositions of critical thinking. Finally , this study illustrated that the insider action research was a fitting methodology as it offered a systematic approach for educators to unravel the connections made between pedagogy, research and change. Its applicability as an appropriate methodology also served to support the emerging trend of moving nursing research toward an evidence-based model as the basis for advancing educational practices in nursing education.
Optimal Emergency Frequency Control Based on Coordinated Droop in Multi-Infeed Hybrid AC-DC System

description: In multi-infeed hybrid AC-DC (MIDC) systems, the asynchronous interconnection between regional grids, the complicated system dynamics and possible cascading failures have an enormous effect on the frequency stability. In order to deal with the frequency instability problems in emergency situations, this paper proposes a decentralized emergency frequency control strategy based on coordinated droop for the MIDC system. First, a P-f droop control for LCC-HVDC systems is introduced and the coordinated droop mechanism among LCC-HVDC systems and generators is designed. Then, to reasonably allocate the power imbalance among LCC-HVDC systems and generators, an optimal emergency frequency control (OEFC) problem is formulated, and the optimal droop coefficients are selected in a decentralized approach, which can deal with various control objectives. A Lyapunov stability analysis shows that the closed-loop equilibrium is locally asymptotically stable considering the LCC-HVDC dynamics. The effectiveness of the proposed emergency control strategy is verified through simulations.

description: More than a decade ago, path dependence turned out to become a promising research program for agricultural economics. This article reviews important trends in path dependence research and highlights its role in the economics of technology, institutional economics, agricultural economics, and organization theory. Due to potential inefficiencies of path dependent processes, more and more researchers focus on path creation which has as yet not been understood very well. The implications of these recent developments for research questions and methodology of agricultural economics are sketched.

The Dynamics of Two Massive Planets on Inclined Orbits

description: The significant orbital eccentricities of most giant extrasolar planets may have their origin in the gravitational dynamics of initially unstable multiple planet systems. In this work, we explore the dynamics of two close planets on inclined orbits through both analytical techniques and extensive numerical scattering experiments. We derive a criterion for two equal mass planets on circular inclined orbits to achieve Hill stability, and conclude that significant radial migration and eccentricity pumping of both planets occurs predominantly by 2:1 and 5:3 mean motion resonant interactions. Using Laplace-Lagrange secular theory, we obtain analytical secular solutions for the orbital inclinations and longitudes of ascending nodes, and use those solutions to distinguish between the secular and resonant dynamics which arise in numerical simulations. We also illustrate how encounter maps, typically used to trace the motion of massless particles, may be modified to reproduce the gross instability seen by the numerical integrations. Such a correlation suggests promising future use of such maps to model the dynamics of more coplanar massive planet systems.

description: Do algorithms for drawing graphs pass the Turing Test? That is, are their outputs indistinguishable from graphs drawn by humans? We address this question through a human-centred experiment, focusing on `small' graphs, of a size for which it would be reasonable for someone to choose to draw the graph manually. Overall, we find that hand-drawn layouts can be distinguished from those generated by graph drawing algorithms, although this is not always the case for graphs drawn by force-directed or multi-dimensional scaling algorithms, making these good candidates for Turing Test success. We show that, in general, hand-drawn graphs are judged to be of higher quality than automatically generated ones, although this result varies with graph size and algorithm.

description: Numerous companies in the Austrian food industry have already been certified in accordance with the ISO 9000 standards. However, the introduction of a quality management system in a company alone does not guarantee continuous improvement as required by the standard ÖNORM ISO 9001:2000. In order to be successful when introducing and maintaining a quality management system in a company, a number of important factors must be considered. These success factors are derived from the „European Foundation for Quality Management (EFQM) Model for Business Excellence“. The purpose of the EFQM Model is to support the internal assessment of the quality management within a company, and it can be regarded as a motor for internal improvement. In particular, for companies planning to introduce a quality management system it is very useful since it tells them which factors have to be taken into account even before they introduce the system. Basically, the EFQM defines a specific weighting of the 9 success factors of the model. The aim of the study is to evaluate the pre-determined weighting of the EFQM success factors for the Austrian food industry.

description: In ‘dissipative’ dynamical systems, variables evolve asymptotically toward low‐dimensional ‘attractors’ that define their dynamical properties. Unfortunately, real‐world dynamical systems are generally too complex for us to directly observe these attractors. Fortunately, there is a method—‘phase space reconstruction’—that can be used to indirectly detect attractors in real‐world dynamical systems using time series data on a single variable (Broomhead and King, 1985; Schaffer and Kott, 1985; Kott et al, 1988; Williams,1997). Armed with this knowledge, we can formulate more accurate and informative models of real‐world dynamical systems. We begin by introducing the concept of phase space attractors within the context of a dynamic ISLM model. We next demonstrate how phase space reconstruction faithfully reproduces one of the model’s attractors. Finally, we discuss how phase space reconstruction fits into a more general ‘diagnostic’ modeling approach that relies on historical data to guide and test the deterministic formulation of theoretical dynamical models. As an example of diagnostic modeling, we test how closely the attractor generated by the dynamic ISLM model visually approximates the attractor reconstructed from time series data on real‐world interest rates.

description: The Italian Industrial Districts (IDs) are considered to be one of the main reasons for the rapid industrial development and success of Italy since the Second World War. The SME's have also played an important role in this. In this paper we outline the general characteristics of the ID approach and the main structural changes in the new millennium, due to them facing the process of globalization. The distinctive figures of the agrifood districts and their mosaic style of development are than analysed to highlight the similarities and differences between them and the other IDs. First show that they are more relevant and that their geographical distribution is more important than those of other recently analysed Italian ID's. The different zones of origin of agrifood districts and their specialized production is often related to typical or high‐quality products, with a strong connection to territorial traditions and manufacturing skills. These characteristics make agrifood districts different in some ways from other ID's where the declining “district effect” has been noted due to the general difficulties of Italian manufacturing industries. We will analysis these general structural changes focusing on the districts of the meat industry.
Quantum geometry and black hole entropy: inclusion of distortion and rotation

description: Equilibrium states of black holes can be modelled by isolated horizons. If the intrinsic geometry is spherical, they are called type I while if it is axi-symmetric, they are called type II. The detailed theory of geometry of quantum type I horizons and the calculation of their entropy can be generalized to type II, thereby including arbitrary distortions and rotations. The leading term in entropy of large horizons is again given by 1/4th of the horizon area for the same value of the Barbero-Immirzi parameter as in the type I case. Ideas and constructions underlying this extension are summarized.
