description: Abstract

Challenges arise as the public transport fare collection process becomes complicated, inefficient, and prone to error by man due to mistakes such as a faulty human error prone fare evasive and also lengthy processing times. This work focuses on creating an RFID-Based Bus Ticketing and Stage Switching System based on NodeMCU to deal with these challenges. The proposed system automatically collects fares and tracks the stages by scanning RFID cards at the time of boarding and alighting, facilitating the computation of fares according to the number of stages traveled. The NodeMCU microcontroller processes RFID data, integrates stage-switching for updation of fares, and uses IoT to send real-time data to the central server for efficient management. Reduced human error, reduced fare evasion, efficiency, and scalability make it a cost-effective solution for modernizing public transportation ticketing systems.

description: There has been great interest in recent decades in “ecosystem services”. One of the services most often mentioned is the retention of nutrients. I construct a simple model of agricultural land use under a regulatory requirement that nutrient loading cannot exceed a fixed ceiling develop three propositions. First, when the regulatory constraint is relatively weak there will be a corner solution in which no land is set aside to provide the service of nutrient retention. Second, for any given regulatory constraint there is in general a minimum amount of land that would be set aside to provide ecosystem services, regardless of the efficiency with which preserved land provides the nutrient retention function. Third, there is sort of paradox of value: the more valuable it is to set some land aside for nutrient retention, the less land in total would optimally be preserved for this purpose. I illustrate the implications of this model with an application to the Chesapeake Bay watershed. Estimates reported in the literature suggest that land retained in natural cover could prove very effective in retaining reactive nitrogen and other nutrients. If so, there is a sort of “good news/bad news” scenario for conservation advocates touting the importance of ecosystem services. The good news is that the ecosystem service of nitrogen retention is, in fact, likely to be very valuable. The bad news is that “a little may go a long way”: setting aside small areas of land may be sufficient.

description: We prove the applicability of the Weighted Energy-Dissipation (WED) variational principle [50] to nonlinear parabolic stochastic partial differential equations in abstract form. The WED principle consists in the minimization of a parameter-dependent convex functional on entire trajectories. Its unique minimizers correspond to elliptic-in-time regularizations of the stochastic differential problem. As the regularization parameter tends to zero, solutions of the limiting problem are recovered. This in particular provides a direct approch via convex optimization to the approximation of nonlinear stochastic partial differential equations.

description: Economists have long been interested in explaining the spatial distribution of economic activity, focusing on what factors motivate profit‐maximizing firms when they choose to open a new plant or expand an existing facility. We begin our paper with a general discussion of the theory of plant location, including the role of taxes and agglomeration economies. However, our paper focuses on the theory, evidence, and implications of the role of environmental regulations in plant location decisions. On its face, environmental regulation would not necessarily be expected to alter location decisions, since we would expect Federal regulation to affect all locations in the United States essentially equally. It turns out, however, that this is not always the case as some geographic areas are subject to greater stringency. Another source of variation is differences across states in the way they implement and enforce compliance with Federal regulation. In light of these spatial differences in the costs of complying with environmental regulations, we discuss three main questions in this survey: Do environmental regulations affect the location decisions of polluting plants? Do states compete for polluting plants through differences in environmental regulation? And, do firms locate polluting plants disproportionately near poor and minority neighborhoods?

description: Molecular absorption of infrared radiation is generally due to ro-vibrational electric-dipole transitions. Electric-quadrupole transitions may still occur, but they are typically a million times weaker than electric-dipole transitions, rendering their observation extremely challenging. In polyatomic or polar diatomic molecules, ro-vibrational quadrupole transitions have never been observed. Here, we report the first direct detection of quadrupole transitions in water vapor. The detected quadrupole lines have intensity largely above the standard dipole intensity cut-off of spectroscopic databases and thus are important for accurate atmospheric and astronomical remote sensing.

description: We put constraints on the degenerate higher-order scalar-tensor (DHOST) theories using the Planck 2018 likelihoods. In our previous paper, we developed a Boltzmann solver incorporating the effective field theory parameterised by the six time-dependent functions, $α_i$ $(i={\rm B},{\rm K},{\rm T},{\rm M},{\rm H})$ and $β_1$, which can describe the DHOST theories. Using the Markov-Chain Monte-Carlo method with our Boltzmann solver, we find the viable parameter region of the model parameters characterising the DHOST theories and the other standard cosmological parameters. First, we consider a simple model with $α_{\rm K} = Ω_{\rm DE}(t)/Ω_{\rm DE}(t_0)$, $α_{\rm B}=α_{\rm T}=α_{\rm M}=α_{\rm H}=0$ and $β_1=β_{1,0}Ω_{\rm DE}(t)/Ω_{\rm DE}(t_0)$ in the $Λ$CDM background where $t_0$ is the present time and obtain $β_{1,0}=0.032_{-0.016}^{+0.013}$ (68\% c.l.). Next, we focus on another theory given by $\mathcal{L}_{\rm DHOST} = X + c_3X\Boxϕ/Λ^3+ (M_{\rm pl}^2/2+c_4X^2/Λ^6)R + 48c_4^2X^2/(M_{\rm pl}^2Λ^{12}+2c_4Λ^6X^2)ϕ^μϕ_{μρ}ϕ^{ρν}ϕ_ν$ with $X:=\partial_μϕ\partial^μϕ$ and two positive constant parameters, $c_3$ and $c_4$. In this model, we consistently treat the background and the perturbations, and obtain $c_3 = 1.59^{+0.26}_{-0.28}$ and the upper bound on $c_4$, $c_4<0.0088$ (68\% c.l.).

description: Electronic structure of layered LiNiO2 has been controversial despite numerous theoretical and experimental reports regarding its nature. We investigate the charge densities, lithium intercalation potentials and Li diffusion barrier energies of LixNiO2 (0.0 < x < 1.0) system using a truly ab-initio method, diffusion quantum Monte Carlo (DMC). We compare the charge densities from DMC and density functional theory (DFT) and show that local and semi-local DFT functionals yield spin polarization densities with incorrect sign on the oxygen atoms. SCAN functional and Hubbard-U correction improves the polarization density around Ni and O atoms, resulting in smaller deviations from the DMC densities. DMC accurately captures the p-d hybridization between the Ni-O atoms, yielding accurate lithium intercalation voltages, polarization densities and reaction barriers.
An investigation into the implementation of Words their Way as a classroom word study program

Publisher: name: The University of British Columbia
Year: 2014

description: The purpose of my research is to survey teachers in my district about the usage and implementation of a word study program called Words Their Way (Bear, Invernizzi, Templeton & Johnston, 2008). Reviews of literature and previous research pertaining to spelling acquisition theories, word sorting, and teacher implementation of programs support the use of the program and help to explain why wide-spread implementation is not occurring. District literacy coaches anecdotally report that few teachers are implementing the program. My research questions are: What obstacles impede the implementation of Words Their Way (Bear et al, 2008) as a word study program in classrooms? What do teachers believe would support implementation to make it more successful? The major source of data was an online survey administered to elementary school teachers in one district who teach Language Arts in a classroom setting. I investigated their views on implementing, and their classroom experiences with, Words Their Way (Bear et al, 2008). Other data sources included a research journal and anecdotal field notes. In response to the research findings, staff in-service opportunities, in the form of classroom demonstrations, workshops and mentorship, were created and offered.

description: This research investigates the influencing variables that affect the likelihood of choosing car-sharing if it launches in the Greater Cairo Metropolitan Area, Egypt. It adopts a binary logistic regression model to analyze the findings of an online stated preference survey. The results include 419 valid responses with different choice scenarios, which are based on the revealed preference of each respondent. The generated model shows statistical significance for age, car ownership, cost, and buffer time of the current mode of transport, travel time, and leisure trips. In addition, car-sharing experience, public transit, ride-hailing, walking, and biking also have significant effects. The highest-impact attributes are the car-sharing cost and access time, as the combination of setting the fare to 2 EGP per minute and limiting the access time of the shared vehicle to nearly 5 min achieved a likelihood of choosing car-sharing in nearly 77% of the responses.

description: The management of non-native invasive species is a complex but crucial task given the potential for economic and environmental damages. For many invasions the development of socially optimal control strategies requires more than is offered by the single-species, single-control models that have dominated this area of research. We develop a general stochastic optimal control framework that accommodates multiple interacting species while accounting for uncertainty in the temporal population dynamics. This extension to the current line of bioeconomic control models allows for the design of optimal management strategies that utilize both chemical and biological controls in an environment of uncertainty and irreversibility. We demonstrate the benefits of combining chemical and biological controls in long term management strategies through a case study of the hemlock woolly adelgid infestation in the eastern United States. In this application we find that the introduction of natural predators is usually sufficient to manage the infestation, though the availability of chemical controls is important when the detection of an invasion or the subsequent response is delayed.

description: The “social cost of carbon” (SCC) is the present value of the future damages from one additional unit of carbon emissions in a particular year. This paper develops a simple model for calculating the social cost of carbon. The model includes the essential ingredients for calculating the SCC at the global scale, and is designed to be transparent and easy to use by decision-makers and non-specialists. We use the model to compare estimates of the SCC under certainty and uncertainty in a Monte Carlo analysis. We find that, due to the combined effects of uncertainty and risk aversion, the certainty-equivalent SCC can be substantially larger than the expected value of the SCC. In our Monte Carlo simulation, the certainty-equivalent SCC corresponds to the 97th percentile of the simulated probability distribution of the deterministic SCC. We also compare the approximate present value of benefits estimated using the SCC to the exact value of compensating variation in the initial period for a wide range of hypothetical emission reduction policies.

description: The Belt and Road Initiative (BRI) is an ambitious infrastructure and development project promoting sustainable economic growth through facilitating prosperous trade across Eurasia and Africa; however, its potential remains underexploited. Logistics networks along BRI routes face several challenges that hinder efficient operations. In addition, although uncertain of how the initiative will develop, logistics and supply chain management (LSCM) practitioners must align their networks with future developments. This study aims to synthesize current barriers to the BRI from an LSCM perspective; propose strategies for dealing with them; and outline and assess conceivable BRI development scenarios to create awareness for possible international logistics network developments. The study builds on a structured and moderated Nominal Group Technique exercise among 15 LSCM professionals to extract current barriers, mitigation strategies, and potential development scenarios, followed by a survey among 52 LSCM professionals to assess those issues. The study synthesizes and assesses 17 BRI barriers for LSCM practice and proposes 20 strategies for dealing with them, assessed in terms of effectiveness and complexity. Moreover, 14 development scenarios are assessed in terms of their probability of becoming reality and impact on the vulnerability of logistics networks, categorized into four scenario clusters (monitor, prepare, propel, and exploit) for guiding LSCM practice.

Numerical analysis of the data rules out the possibility of a gap with nodes.

We studied their chemical composition, crystal and electronic structures, morphology and hyperfine properties as a function of the Co/Fe content of the samples. Our results demonstrate that Co cations exhibit a slightly lower oxidation state than Fe ones, resulting in a higher oxygen non-stoichiometry d for Co-rich samples. In addition, the values of d determined in this work for nanostructured samples are much higher than those reported in the literature for bulk materials. This can be attributed to the high degree of defects in nanomaterials and is probably one important factor in the high electrochemical performance for the oxygen reduction reaction of nanostructured La0.6Sr0.4Co1-yFeyO3-d IT-SOFC cathodes, which have been reported in a previous work.

description: This deliverable describes the sequencing of metagenomes and metatranscriptomes of the most promisingmicrobiomes with efficient degrading activities for the three use cases. These data (currently underacquisition) will be analysed to: i) reconstruct the genomes of each individual bacteria from the consortia(MAGs), ii) predict their biochemical pathways and potential role in the consortia, and iii) identify the genesand pathways that are over-expressed or repressed when the consortia are grown on contaminants andduring degradation. The metagenome and transcriptome were planned on the six most promisingmicrobiomes, but were actually performed on ten.This information will be used to select the best microbiomes for the next steps, and mainly for directedevolution. In addition, these data will be further used to target functional genes in bioaugmentation andbioremediation assays during pilot and field testing of our microbiomes.As a complement, ongoing actions will result in SIP-metabarcoding and metagenomic datasets that will beincluded in an updated version of the deliverable prior to M36.

description: This study examined the determinants of the food security status of low income households in North-East Trinidad. Food security status was assessed using the 18-item U.S. Household Food Security Survey Module of the United States Department of Agriculture (USDA). The sample consisted of caregivers of primary school children aged 7-12 years who reside in two regions (St. Andrew-St. David and St. George East) in North-East Trinidad. There were 304 respondents, 90.13% female and 9.87% male. Multiple linear regression analysis was used to determine the relationship between food security status and household socio-demographic characteristics. Results show gender, marital status and income were the only three useful predictors of household food insecurity. Gender and marital status were both positive and significant at the 0.05 significance level. The coefficient for income was negative and significant at the 0.05 significance level. This study found that more female-headed households participated in the study and were more food insecure as compared with male-headed households; additionally, females were more likely to experience mild and moderate food insecurity with hunger. More female headed households participated in the study and were found to be more food insecure as compared with the male headed households.

description: Cryptons are metastable bound states of fractionally-charged particles that arise generically in the hidden sectors of models derived from heterotic string. We study their properties and decay modes in a specific flipped SU(5) model with long-lived four-particle spin-zero bound states called {\it tetrons}. We show that the neutral tetrons are metastable, and exhibit the tenth-order non-renormalizable superpotential operators responsible for their dominant decays. By analogy with QCD, we expect charged tetrons to be somewhat heavier, and to decay relatively rapidly via lower-order interactions that we also exhibit. The expected masses and lifetimes of the neutral tetrons make them good candidates for cold dark matter (CDM), and a potential source of the ultra-high energy cosmic rays (UHECRs) which have been observed, whereas the charged tetrons would have decayed in the early Universe.

description: We present photometric and spectroscopic observations of the nearby ($D\approx28$ Mpc) interacting supernova (SN) 2019esa, discovered within hours of explosion and serendipitously observed by the Transiting Exoplanet Survey Satellite (TESS). Early, high cadence light curves from both TESS and the DLT40 survey tightly constrain the time of explosion, and show a 30 day rise to maximum light followed by a near constant linear decline in luminosity. Optical spectroscopy over the first 40 days revealed a highly reddened object with narrow Balmer emission lines seen in Type IIn supernovae. The slow rise to maximum in the optical lightcurve combined with the lack of broad H$α$ emission suggest the presence of very optically thick and close circumstellar material (CSM) that quickly decelerated the supernova ejecta. This CSM was likely created from a massive star progenitor with an $\dot{M}$ $\sim$ 0.3 M$_{\odot}$ yr$^{-1}$ lost in a previous eruptive episode 3--4 years before eruption, similar to giant eruptions of luminous blue variable stars. At late times, strong intermediate-width Ca II, Fe I, and Fe II lines are seen in the optical spectra, identical to those seen in the superluminous interacting SN 2006gy. The strong CSM interaction masks the underlying explosion mechanism in SN 2019esa, but the combination of the luminosity, strength of the H$α$ lines, and mass loss rate of the progenitor all point to a core collapse origin.

description: This paper set out to determine for cocoa farmers in Trinidad and Tobago their happiness status, the factors that determine this status as well as the distribution of their happiness efficiency. A Cantril Self Anchoring Ladder scale was used to measure the Present Happiness Score and Future Happiness Score. Information for the estimations was obtained from a mail survey, in which 102 farmers in Trinidad and Tobago registered with the Cocoa and Coffee Industry Board (CCIB) responded. Two types of analyses were undertaken. For the present life satisfaction, stochastic frontier analysis was used to estimate a “happiness” frontier and the happiness efficiency of a farmer was then measured by the closeness of this farmer to this efficiency frontier. Ordinary linear regression was also used to investigate the factors affecting the future life satisfaction score (or future happiness score) for the farmers. With respect to the present life satisfaction, farmers who were happier were those whose main crop was not cocoa; older farmers, farmers with smaller household sizes, as well as farmers who were in favour of the new payment system. Household size significantly increased the variance of the inefficiency error term while the farm size negatively affected the idiosyncratic error term of the happiness function.

description: The spectrum of the Laplace operator in a curved strip of constant width built along an infinite plane curve, subject to three different types of boundary conditions (Dirichlet, Neumann and a combination of these ones, respectively), is investigated. We prove that the essential spectrum as a set is stable under any curvature of the reference curve which vanishes at infinity and find various sufficient conditions which guarantee the existence of geometrically induced discrete spectrum. Furthermore, we derive a lower bound on the distance between the essential spectrum and the spectral threshold for locally curved strips. The paper is also intended as an overview of some new and old results on spectral properties of curved quantum waveguides.

Weaving words and images : using visual strategies to improve idea generation and writing strategies of primary writers
Creators: name: Dennis, Esther Lenore
Publisher: name: The University of British Columbia
Year: 2014

description: This eight week study supports the view that literacy learning is multimodal and it contributes to existing research (Dyson, 1986: Hubbard, 1989: Olshansky, 2006: Skupa, 1985) on the "Communicability of drawing and writing as vehicles through which children make and share meaning" (Leigh & Heid, 2008, p.1). Focused on using visual art, specifically drawing, in the planning stages before and during the writing process, this study was conducted to explore if there is a value in privileging the role of drawing to improve children's writing stamina and idea generation. The subjects were 17 grade two and three students in an elementary classroom. Data collected consisted of teacher observational notes, conferences with children, a survey, and portfolios of the children's writing and drawing. Patterns and themes were identified, relating to their (a) use of drawing as a pre-writing or planning strategy, (b) use of drawing to overcome writer's block and reducing cognitive demands, (c) drawings as idea banks, (d) affective responses to drawing and writing, (e) recursive use of writing and drawing, and (f) embedding of writing in drawings. On the basis of these patterns, inferences were made about written language development and the power in children's use of art, specifically drawing, when it is valued as a conduit for understanding how children construct meaning. It was concluded that drawing, before and during the writing process, at least in terms of the generation of ideas and children's stamina for writing tasks, is an effective form of planning for writing. Given the very diversity in personal learning styles, and ways of knowing, there is a real benefit for children to approach the writing process using alternative modes of representation.

description: This study examined the average profitability of coconut farming in Guyana, as this is a major crop associated with agricultural diversification and improving the level of food security in Guyana, both through the provision of income for improved access to food for farmers, as well as providing food products for the Guyanese households. The main objective of the study was to compare the average profitability of the two main producing agro-climatic zones of Guyana the coastal area or Regions versus the riverain or Pomeroon area (in Region 2). The study also sought to discover the factors that determine the average profitability of the coconut farming. Primary data were collected from 201 coconut producers from the two major producing areas. A regression model was used to discover the factors that significantly determine the profit per acre of coconut farming. The results indicated that the variety of coconut grown and the total labour cost were the most significant variables in determining the average profitability of coconut production. The age of the farmer and his/her educational level also tended to affect the average profitability of the farms. The Chow test carried out indicated a structural difference between the two areas of coconut production with respect to the average profitability of coconut production, whereby the tall variety of coconut was present on a significantly greater number of farms in the Coastal area, than in the Pomeroon area, which had farms with higher average profitability and dwarf varieties. These dwarf varieties allowed a wider range of coconut products including coconut water. These results help to explain the developments in the coconut industry in Guyana where the Pomeroon is now touted to become “the coconut capital of Guyana”, and coconut water the “national drink”.

Distributed Stochastic Nonconvex Optimization and Learning based on Successive Convex Approximation

description: We study distributed stochastic nonconvex optimization in multi-agent networks. We introduce a novel algorithmic framework for the distributed minimization of the sum of the expected value of a smooth (possibly nonconvex) function (the agents' sum-utility) plus a convex (possibly nonsmooth) regularizer. The proposed method hinges on successive convex approximation (SCA) techniques, leveraging dynamic consensus as a mechanism to track the average gradient among the agents, and recursive averaging to recover the expected gradient of the sum-utility function. Almost sure convergence to (stationary) solutions of the nonconvex problem is established. Finally, the method is applied to distributed stochastic training of neural networks. Numerical results confirm the theoretical claims, and illustrate the advantages of the proposed method with respect to other methods available in the literature.

title: Accountability, Its use as a strategy in the management of school teaching staff
Creators: name: Wallis, William George Kendall
Publisher: name: The Open University
Year: 1993

description: In this thesis. I have examined some of the ways in which the notion of accountability appears to influence the management of school teaching staff. As a background to this analysis I have referred, both to the literature appertaining to management and to those broader sociological traditions that have concerned themselves with questions of authority and order. From this general theoretical background I isolate a number of forms of accountability, noting how these are capable of both independent influence and more complex, compound modes of operation. In an attempt to provide illustrative examples of many of these aspects of accountability I have examined four case studies. Each of these is based upon a formal dispute, involving both head and assistant teachers. From this analysis I develop a range of points, these leading to a number of tentative conclusions. Most important of these, concerns the distinction between accountability as a means of motivating action and as a way of retrospectively explaining, justifying and ultimately legitimating actions. In examining these various manifestations of accountability, I refer, both to the theoretical basis and to the operational characteristics of the concept, developing such notions as the nature of managerial strategy and the influence of micro politics. The case study work helps to show how this division, between accountability as a motivating force and, as a means to explanation, is not a simple division, but one based upon a complex relationship that is both confused and confusing.
Control of Spatial-Temporal Congested Traffic Patterns at Highway Bottlenecks

description: A microscopic theory of control of spatial-temporal congested traffic pattern at freeway bottlenecks is presented. Based on empirical spatial-temporal features of congested patterns at freeway bottlenecks which have recently been found, different control strategies for prevention or reducing of the patterns are simulated and compared. The studied control strategies include the on-ramp metering with feedback and automatic cruise control (ACC) vehicles. A recent microscopic traffic flow model within the author's three-phase traffic theory is used for validation of spatial-temporal congested pattern control.

description: Niche arguments for certain idiosyncratic theological practices often arise from personal readings and interpretations of various religious texts, particularly the Bible. This note regards one such practice, being the refusal to engage with members of other faith communities based on a particular reading of the New Testament book of 2 John, and analyzes why such a belief in the exegetical context of the passage in question in order to define what said passage actually asserts.
