description: This report summarizes the results of the North Dakota Land Valuation Model using a capitalization rate of 9.5 percent. The 2003 North Dakota Legislature amended the statute that defines the capitalization rate to be used in this analysis. This legislative change places a minimum of 9.5 percent for the capitalization rate if the calculated value falls below this level. For 2003, the capitalization rate formula yielded a rate of 8.53 percent, thus the minimum of 9.5 percent was used. This model is used annually to estimate average land values by county, based on the value of production from the land. The county land values developed from this procedure form the basis for the 2003 valuation of agricultural land for real estate tax assessment. The average all land value from this analysis is multiplied by the total acres of agricultural land on the county abstract to determine each county's total agricultural land value for taxation purposes. The State Board of Equalization compares this value with the total value assessed to agricultural property in each county. Each county is required by state statute to assess a total value of agricultural property within 5 percent of this value. The average value per acre of all agricultural land in North Dakota decreased by 5.3 percent in this analysis. The increase in the capitalization rate alone accounted for an average decrease in land values of 6.2 percent.

description: This thesis explores the global ascent of fast fashion, investigating its significant impact on textile and garment production and the resultant environmental consequences stemming from accelerated production processes. It identifies the environmental and ethical ramifications of the stages of the linear garment lifecycle, offering a comprehensive perspective of the modern fashion industry. Through an exploration of consumer awareness and behavior, this paper uncovers the influential role played by consumers in driving the proliferation of fast fashion practices. Consumer shifts toward affordable, trendy clothing have propelled the fast fashion industry, reflecting the direct link between consumer choices and fashion production. Furthermore, this thesis investigates the paradoxical relationship between the sustainability advocacy of consumers and their concurrent engagement in consumption habits that perpetuate an unsustainable "take, make, dispose" clothing cycle. By delving into consumer dynamics and psychology, this research unravels the underlying motivations that drive fashion consumers' purchasing decisions. It subsequently evaluates how past consumer behavior has effectively instigated shifts toward sustainable initiatives within the fashion industry, particularly through engagement with the secondhand fashion market. Furthermore, past consumer affinity for secondhand fashion companies is analyzed to glean insights into strategies that sustainable brands can adopt to enhance consumer engagement and participation.

description: Mining association rules from data streams is a challenging task due to the (typically) limited resources available vs. the large size of the result. Frequent closed itemsets (FCI) enable an efficient first step, yet current FCI stream miners are not optimal on resource consumption, e.g. they store a large number of extra itemsets at an additional cost. In a search for a better storage-efficiency trade-off, we designed Ciclad,an intersection-based sliding-window FCI miner. Leveraging in-depth insights into FCI evolution, it combines minimal storage with quick access. Experimental results indicate Ciclad's memory imprint is much lower and its performances globally better than competitor methods.

description: We present the first complete measurement of the Chinese Internet topology at the autonomous systems (AS) level based on traceroute data probed from servers of major ISPs in mainland China. We show that both the Chinese Internet AS graph and the global Internet AS graph can be accurately reproduced by the Positive-Feedback Preference (PFP) model with the same parameters. This result suggests that the Chinese Internet preserves well the topological characteristics of the global Internet. This is the first demonstration of the Internet's topological fractality, or self-similarity, performed at the level of topology evolution modeling.

description: Geometric scattering has recently gained recognition in graph representation learning, and recent work has shown that integrating scattering features in graph convolution networks (GCNs) can alleviate the typical oversmoothing of features in node representation learning. However, scattering often relies on handcrafted design, requiring careful selection of frequency bands via a cascade of wavelet transforms, as well as an effective weight sharing scheme to combine low- and band-pass information. Here, we introduce a new attention-based architecture to produce adaptive task-driven node representations by implicitly learning node-wise weights for combining multiple scattering and GCN channels in the network. We show the resulting geometric scattering attention network (GSAN) outperforms previous networks in semi-supervised node classification, while also enabling a spectral study of extracted information by examining node-wise attention weights.
Long View: Practical Advertising Against Overconsumption For An Anti Earth-Death Future
Creators: name: Williams, Rachel
Publisher: name: The University of Texas at Austin
Year: 2023
Subjects: Long View

description: “Long View” is a creative advertising campaign that seeks to educate viewers about planned obsolescence in tech, and to promote a solution to the overconsumption of technology through urging viewers to buy products that can be repaired. Specifically, this campaign condemns Apple products, which are made to break, and points users towards a cradle-to-cradle smartphone made by Nokia. Cradle-to-cradle design refers to products that are designed to never become waste through regenerative design. In the promotion of this smartphone, the actual advertisements themselves are designed through cradle-to-cradle principles as well, leveraging sunlight, moss, rain, and renewable or repurposed materials to spread the messaging, instead of printing anything new. By using the tools of creative advertising to advocate against overconsumption, this project poses a practical solution to how our relationship to products needs to change in the era of climate change.
Models for two-state disease processes with applications to relapsing-remitting multiple sclerosis
Creators: name: Brumm, Jochen
Publisher: name: University of British Columbia
Year: 2009

description: In diseases like relapsing-remitting multiple sclerosis (MS), patients experience repeated transitions between symptom-free and symptomatic disease states (the symptomatic state is called an exacerbation). Analyses for this kind of data commonly ignore the information available on the second state (the lengths of the exacerbations, for example). In this thesis, we consider models that incorporate the second state into the analyses. The basic stochastic models are Markov chains, alternating renewal processes and marked point processes. For the Markov chains and alternating renewal process models, we consider simple fixed effects models as well as random effects models where the random effects are introduced to allow for heterogeneity between patients and correlation of data on one patient. For these models, the statistical inference is based on maximum likelihood. For the marked point process model, we use a generalized estimating equation approach. We apply these models to a data set from a MS clinical trial. The aim of the analyses is to relate the available covariates to the disease process. We do not attempt a comprehensive analysis of the data set, rather the aim here is to see what can be achieved and which questions can be addressed with the different models.

description: This report provides estimates of the lignite industry's contribution to the North Dakota economy, using key economic indicators such as retail trade activity, personal income, total business activity, employment, and tax revenues. The estimates are based on actual industry expenditures for 2003 and projected expenditures for 2004. This analysis contains two measures of the relative importance of the lignite energy industry in North Dakota. First, the industry's share of the state's total sales to final demand (or exports) is evaluated. Second, the business volume generated by the industry is compared to the total gross business volume for the state. Expenditures were obtained from a survey of firms involved in lignite-related activities (mining or conversion) in North Dakota. Finally, wages paid by the coal mining sector are compared to those paid by other sectors of the state economy.

description: We propose the construction of electromagnetic (or electronic) switches and beam splitters using chaotic two-dimensional multi-port waveguides. A prototype two-port waveguide is locally deformed in order to produce a ternary incomplete horseshoe proper of mixed phase space (chaotic regions surrounding islands of stability where motion is regular). Due to tunneling to the phase space stability islands the appearance of quasi-bound states (QBS) is induced. Then, we attach transversal ports to the waveguide on the deformation region in positions where the phase space structure is only slightly perturbed. We show how QBS can be guided out of the waveguide through the attached transversal ports giving rise to frequency selective switches and beam splitters.

description: Recently it has been argued that entropy can be a direct measure of complexity, where the smaller value of entropy indicates lower system complexity, while its larger value indicates higher system complexity. We dispute this view and propose a universal measure of complexity based on the Gell-Mann's view of complexity. Our universal measure of complexity bases on a non-linear transformation of time-dependent entropy, where the system state with the highest complexity is the most distant from all the states of the system of lesser or no complexity. We have shown that the most complex is optimally mixed states consisting of pure states i.e., of the most regular and most disordered which the space of states of a given system allows. A parsimonious paradigmatic example of the simplest system with a small and a large number of degrees of freedom, is shown to support this methodology. Several important features of this universal measure are pointed out, especially its flexibility (i.e., its openness to extensions), ability to the analysis of a system critical behavior, and ability to study the dynamic complexity.

description: Blockchain Technology acts as a buzzword, an innovative tech solution that can fix almost any logistical issue. How does this innovative technology affect the social well-being of its users? In this paper, I have explored the essence of what Blockchain Technology is, how it is used, and finally, the social effect that it has had and has the potential to have. When measuring the effect that technology has on individuals' social well-being I will use the capability approach theory. Evaluating the effect that blockchain has on individuals' well-being by looking at how it alters the control they have over their environment through both political and material control. This analysis will focus on the effect in three specific nations; El Salvador, Kenya, and Venezuela. Using the capability approach offers a lens into individuals' well-being based on their access and capability to control their lives.

description: The muscle synergy concept provides the best framework to understand motor control and it has been recently utilised in many applications such as prosthesis control. The current muscle synergy model relies on decomposing multi-channel surface Electromyography (EMG) signals into a synergy matrix (spatial mode) and its weighting function (temporal mode). This is done using several matrix factorisation techniques, with Non-negative matrix factorisation (NMF) being the most prominent method. Here, we introduce a 4th-order tensor muscle synergy model that extends the current state of the art by taking spectral information and repetitions (movements) into account. This adds more depth to the model and provides more synergistic information. In particular, we illustrate a proof-of-concept study where the Tucker3 tensor decomposition model was applied to a subset of wrist movements from the Ninapro database. The results showed the potential of Tucker3 tensor factorisation in finding patterns of muscle synergies with information about the movements and highlights the differences between the current and proposed model.

description: X-ray free-electron lasers (FEL) deliver ultrabright X-ray pulses, but not the sequences of phase-coherent pulses required for time-domain interferometry and control of quantum states. For conventional split-and-delay schemes to produce such sequences the challenge stems from extreme stability requirements when splitting Angstrom wavelength beams where tiniest path length differences introduce phase jitter. We describe an FEL mode based on selective electron bunch degradation and transverse beam shaping in the accelerator, combined with a self-seeded photon emission scheme. Instead of splitting the photon pulses after their generation by the FEL, we split the electron bunch in the accelerator, prior to photon generation, to obtain phase-locked X-ray pulses with sub-femtosecond duration. Time-domain interferometry becomes possible, enabling the concomitant program of classical and quantum optics experiments with X-rays. The scheme leads to new scientific benefits of cutting-edge FELs with attosecond and/or high-repetition rate capabilities, ranging from the X-ray analog of Fourier transform infrared spectroscopy to damage-free measurements.

description: We consider the following question: given $A \in SL(2,R)$, which potentials $q$ for the second order Sturm-Liouville problem have $A$ as its Floquet multiplier? More precisely, define the monodromy map $μ$ taking a potential $q \in L^2([0,2π])$ to $μ(q) = \tildeΦ(2π)$, the lift to the universal cover $G = \widetilde{SL(2,R)}$ of $SL(2,R)$ of the fundamental matrix map $Φ: [0,2π] \to SL(2,R)$, \[ Φ(0) = I, \quad Φ'(t) = \begin{pmatrix} 0 & 1 q(t) & 0 \end{pmatrix} Φ(t). \] Let $H$ be the real infinite dimensional separable Hilbert space: we present an explicit diffeomorphism $Ψ: G_0 \times H \to H^0([0,2π])$ such that the composition $μ\circ Ψ$ is the projection on the first coordinate. The key ingredient is the correspondence between potentials $q$ and the image in the plane of the first row of $Φ$, parametrized by polar coordinates, which we call the Kepler transform. As an application among others, let $C_1 \subset L^2([0,2π])$ be the set of potentials $q$ for which the equation $-u'' + qu = 0$ admits a nonzero periodic solution: $C_1$ is diffeomorphic to the disjoint union of a hyperplane and cartesian products of the usual cone in $R^3$ with $H$.

description: We consider doubly-periodic travelling waves at the surface of an infinitely deep perfect fluid, only subjected to gravity $g$ and resulting from the nonlinear interaction of two simply periodic travelling waves making an angle $2θ$ between them. \newline Denoting by $μ=gL/c^{2}$ the dimensionless bifurcation parameter ($L$ is the wave length along the direction of the travelling wave and $c$ is the velocity of the wave), bifurcation occurs for $μ=\cos θ$. For non-resonant cases, we first give a large family of formal three-dimensional gravity travelling waves, in the form of an expansion in powers of the amplitudes of two basic travelling waves. "Diamond waves" are a particular case of such waves, when they are symmetric with respect to the direction of propagation.\newline \emph{The main object of the paper is the proof of existence} of such symmetric waves having the above mentioned asymptotic expansion. Due to the \emph{occurence of small divisors}, the main difficulty is the inversion of the linearized operator at a non trivial point, for applying the Nash Moser theorem. This operator is the sum of a second order differentiation along a certain direction, and an integro-differential operator of first order, both depending periodically of coordinates. It is shown that for almost all angles $θ$, the 3-dimensional travelling waves bifurcate for a set of "good" values of the bifurcation parameter having asymptotically a full measure near the bifurcation curve in the parameter plane $(θ,μ).$

description: Purpose To alleviate the spatial encoding limitations of single-shot EPI by developing multi-shot segmented EPI for ultra-high-resolution fMRI with reduced ghosting artifacts from subject motion and respiration. Methods Segmented EPI can reduce readout duration and reduce acceleration factors, however, the time elapsed between segment acquisitions (on the order of seconds) can result in intermittent ghosting, limiting its use for fMRI. Here, "FLEET" segment ordering--where segments are looped over before slices--was combined with a variable flip angle progression (VFA-FLEET) to improve inter-segment fidelity and maximize signal for fMRI. Scaling a sinc pulse's flip angle for each segment (VFA-FLEET-Sinc) produced inconsistent slice profiles and ghosting, therefore, a recursive Shinnar-Le Roux (SLR) RF pulse design was developed (VFA-FLEET-SLR) to generate unique pulses for every segment that together produce consistent slice profiles and signals. Results The temporal stability of VFA-FLEET-SLR was compared against conventional-segmented EPI and VFA-FLEET-Sinc at 3 T and 7 T. VFA-FLEET-SLR showed reductions in both intermittent and stable ghosting compared to conventional-segmented and VFA-FLEET-Sinc, resulting in improved image quality with a minor trade-off in temporal SNR. Combining VFA-FLEET-SLR with acceleration, we achieved a 0.6-mm isotropic acquisition at 7 T--without zoomed imaging or partial Fourier--demonstrating reliable detection of BOLD responses to a visual stimulus. To counteract the increased repetition time from segmentation, simultaneous multi-slice VFA-FLEET-SLR was demonstrated using RF-encoded controlled aliasing. Conclusions VFA-FLEET with a recursive RF pulse design supports acquisitions with low levels of artifact and spatial blur, enabling fMRI at previously inaccessible spatial resolutions with a "full-brain" field of view.

description: This chapter examines how positivity and order play out in two important questions in mathematical economics, and in so doing, subjects the postulates of continuity, additivity and monotonicity to closer scrutiny. Two sets of results are offered: the first departs from Eilenberg's (1941) necessary and sufficient conditions on the topology under which an anti-symmetric, complete, transitive and continuous binary relation exists on a topologically connected space; and the second, from DeGroot's (1970) result concerning an additivity postulate that ensures a complete binary relation on a σ-algebra to be transitive. These results are framed in the registers of order, topology, algebra and measure-theory; and also beyond mathematics in economics: the exploitation of Villegas' notion of monotonic continuity by Arrow-Chichilnisky in the context of Savage's theorem in decision theory, and the extension of Diamond's impossibility result in social choice theory by Basu-Mitra. As such, this chapter has a synthetic and expository motivation, and can be read as a plea for inter-disciplinary conversations, connections and collaboration.

description: The turbulent transport of impurity particles in plasma edge turbulence is investigated. The impurities are modeled as a passive fluid advected by the electric and polarization drifts, while the ambient plasma turbulence is modeled using the two-dimensional Hasegawa--Wakatani paradigm for resistive drift-wave turbulence. The features of the turbulent transport of impurities are investigated by numerical simulations using a novel code that applies semi-Lagrangian pseudospectral schemes. The diffusive character of the turbulent transport of ideal impurities is demonstrated by relative-diffusion analysis of the evolution of impurity puffs. Additional effects appear for inertial impurities as a consequence of compressibility. First, the density of inertial impurities is found to correlate with the vorticity of the electric drift velocity, that is, impurities cluster in vortices of a precise orientation determined by the charge of the impurity particles. Second, a radial pinch scaling linearly with the mass--charge ratio of the impurities is discovered. Theoretical explanation for these observations is obtained by analysis of the model equations.

description: Ultrafast spectroscopy is an important tool for studying photoinduced dynamical processes in atoms, molecules, and nanostructures. Typically, the time to perform these experiments ranges from several minutes to hours depending on the choice of spectroscopic method. It is desirable to reduce this time overhead to not only to shorten time and laboratory resources, but also to make it possible to examine fragile specimens which quickly degrade during long experiments. In this article, we motivate using compressive sensing to significantly shorten data acquisition time by reducing the total number of measurements in ultrafast spectroscopy. We apply this technique to experimental data from ultrafast transient absorption spectroscopy and ultrafast terahertz spectroscopy and show that good estimates can be obtained with as low as 15% of the total measurements, implying a 6-fold reduction in data acquisition time.

description: Reinforcement learning with neural networks (RLNN) has recently demonstrated great promise for many problems, including some problems in quantum information theory. In this work, we apply RLNN to quantum hypothesis testing and determine the optimal measurement strategy for distinguishing between multiple quantum states $\{ ρ_{j} \}$ while minimizing the error probability. In the case where the candidate states correspond to a quantum system with many qubit subsystems, implementing the optimal measurement on the entire system is experimentally infeasible. We use RLNN to find locally-adaptive measurement strategies that are experimentally feasible, where only one quantum subsystem is measured in each round. We provide numerical results which demonstrate that RLNN successfully finds the optimal local approach, even for candidate states up to 20 subsystems. We additionally demonstrate that the RLNN strategy meets or exceeds the success probability for a modified locally greedy approach in each random trial. While the use of RLNN is highly successful for designing adaptive local measurement strategies, in general a significant gap can exist between the success probability of the optimal locally-adaptive measurement strategy and the optimal collective measurement. We build on previous work to provide a set of necessary and sufficient conditions for collective protocols to strictly outperform locally adaptive protocols. We also provide a new example which, to our knowledge, is the simplest known state set exhibiting a significant gap between local and collective protocols. This result raises interesting new questions about the gap between theoretically optimal measurement strategies and practically implementable measurement strategies.

description: We present first results on the quantitative spectroscopic analysis of the photospheric-phase of Type II supernovae (SN). The analyses are based on the non-LTE model atmosphere code, CMFGEN, of Hillier & Miller (1998). A key asset of CMFGEN is its thorough treatment of line-blanketing due to metal species. From its applicability to hot star environments, the main modifications to the source code were to allow a linear velocity law, a power-law density distribution, an adaptive grid to handle the steep H recombination/ionization front occurring in cooler SN models, and a routine to compute the gray temperature structure in the presence of large velocities. In this first paper we demonstrate the ability of CMFGEN to reproduce, with a high level of accuracy, the UV and optical observations of a sample of well observed Type II SN, i.e. SN1987A and SN1999em, at representative stages of their photospheric evolution. Two principal stages of SN are modeled - that where hydrogen is fully ionized, and that in which H is only partially ionized. We provide detailed and accurate line identifications for our sample of epochs. We discuss the impact on the SED of varying the density exponent, the spatial scale of the SN, the value of Rmax and the metallicity; we illustrate the formation sites for selected lines. Both Hydrogen Balmer and Helium lines (when present) are very well reproduced, even for our adopted CNO-equilibrium abundance values adequate for a massive supergiant progenitor star. NII lines are also predicted in the blue-wing of both Hbeta and HeI 5875A, and thus not associated with peculiar absorption/emission far above the photosphere. We finally present a pedagogical discussion of P-Cygni profile formation and explain, e.g., the noticeable blue-shift of Halpha in early time spectra (much abridged abstract).

description: Quantum-dot Cellular Automata (QCA) is a new emerging technology for designing electronic circuits in nanoscale. QCA technology comes to overcome the CMOS limitation and to be a good alternative as it can work in ultra-high-speed. QCA brought researchers attention due to many features such as low power consumption, small feature size in addition to high frequency. Designing circuits in QCA technology with minimum costs such as cells count and the area is very important. This paper presents novel structures of D-latch and D-Flip Flop with the lower area and cell count. The proposed Flip-Flop has SET and RESET ability. The proposed latch and Flip-Flop have lower complexity compared with counterparts in terms of cell counts by 32% and 26% respectively. The proposed circuits are designed and simulated in QCADesigner software.

description: Abstract
Objective: The aim of this scoping review is to identify and analyze perinatal interventions specifically designed or culturally adapted for migrant or women from diverse cultural backgrounds who are pregnant or of childbearing age.
Introduction: Cultural adaptation in perinatal healthcare involves adjusting practices to meet the specific cultural and linguistic needs of migrant mothers or those from culturally diverse backgrounds (Weeks, 2022; Marshall et al., 2021).
Inclusion criteria: The articles included will focus on perinatal interventions. We are interested in practices that were adapted specifically for mothers, pregnant women, or women of childbearing age from a migrant background (all migratory statuses are included) or from culturally diverse communities. Studies published in a language other than English or French that do not directly address perinatal interventions, cultural diversity, or migratory status in the title and abstract will be excluded.
Methods: An exploratory study in line with PRISMA guidelines will be carried out December 2023-February 2024. The main sources consulted will be PsycINFO, EMBASE, MEDLINE, CINAHL. Additional manuscripts found via different sources (snowball, web search) and not yet included in the results of the first four databases, will also be added. Search terms will be in English and French. Researchers will download all references from the four databases and assess whether to include or exclude them from the review. Then, the retained texts will be analyzed in NVivo v.14.

description: An important issue in WTO trade negotiations is whether further liberalization of trade and agricultural policies may help or hinder food security in WTO member countries, especially the developing countries. The WTO recognizes various classifications of countries: developed, developing, least developed (LDC) and net food importing developing (NFIDC). How well do these categories capture issues of food security? This paper employs various methods of cluster analysis (including an approach based on fuzzy sets) and data for 167 countries to identify groups of countries categorized according to five measures of food security: food production per capita, the ratio of total exports to food imports, calories per capita, protein per capita, and the share of the nonagricultural population share. The analysis identifies 12 distinct clusters characterized by similarities and differences across the various measures. The analysis suggests that the LDC category consists of largely food insecure countries, but that there also are food insecure countries that are not LDCs. NFIDCs is less precise as an indicator of food vulnerability, with more than a third of those countries not falling under any of the food insecure groups. Also, the general category of “developing countries” is very heterogeneous and is not very useful if the focus is on issues of food security. Finally, our typology shows that all developed countries are included in food secure categories. This result suggests that the notion of food security introduced as part of the “multifunctionality” of agriculture, or, more generally, among non-trade concerns has a very different meaning in developed and developing countries. In terms of policy implications and the agricultural negotiations, maintaining the same label for two altogether different situations may only obscure the issues being negotiated.

description: The longitudinal resistivity at transitions between integer quantum Hall states in two-dimensional electrons confined to AlAs quantum wells is found to depend on the spin orientation of the partially-filled Landau level in which the Fermi energy resides. The resistivity can be enhanced by an order of magnitude as the spin orientation of this energy level is aligned with the majority spin. We discuss possible causes and suggest a new explanation for spike-like features observed at the edges of quantum Hall minima near Landau level crossings.

Oaxacan parents’ perceptions of literacy learning
Creators: name: Lopez, Mario E.
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to learn about the perceptions that Oaxacan parents, from three different socio-economic status (SES) groups, have about literacy learning. This study intended to answer the following research questions: (1) Are the Oaxacan parents' perceptions of literacy learning consistent with an emergent literacy model? (2) To what extent do these perceptions differ among the three different socio-economic groups? (3) What do Oaxacan parents do to help their children learn to read and write? (4) What did the parents and teachers of the parents interviewed ask them to do to learn to read and write? A survey was adopted for this study. Forty parents were interviewed. A thirtythree- Likert-Type-item-structured interview plus two open-ended questions were used. The interviews were recorded, and then transcribed in their entirety. Results showed that most Oaxacan parents held beliefs consistent with an emergent literacy model. On the other hand, they also held notions consistent with a traditional model. There were more similarities than differences between the SES groups. There were only three items in which the three SES groups differed. Moreover, results showed that Oaxacan parents help their children become literate by providing a wide variety of activities. Reading to/with children was the most valued activity by Oaxacan parents. Finally, most parents were asked to work on literacy skills to learn to read and write. Most parents had to do "endless" letter, syllable and word drills. A limitation of this study was the sample being too small. Implications for researchers, curriculum designers, and teachers were drawn based on the results of this study. It was concluded that this survey should be applied in every classroom as away to learn more about the child's environment and build on his/her previous knowledge and that a library is urgently needed in Oaxaca, Mexico.
