description: We analyze the spectral properties of a very general two-channel fermion-boson transport model in the insulating and metallic regimes, and the signatures of the metal-insulator quantum phase transition in between. To this end we determine the single particle spectral function related to angle-resolved photoemission spectroscopy, the momentum distribution function, the Drude weight and the optical response by means of a dynamical (pseudo-site) density-matrix renormalization group technique for the one-dimensional half-filled band case. We show how the interplay of correlations and fluctuations in the background medium controls the charge dynamics of the system, which is a fundamental problem in a great variety of advanced materials.

description: We exploit an original dataset from a referendum in Peru to study the influence of voting “arrangements” on electoral outcomes. The relative importance of these arrangements (e.g. ballot design) with respect to the fundamentals (e.g. ideology, candidates’ quality) has not been measured. After controlling for a comprehensive set of politicians’ characteristics, we estimate unbiased ballot order effects making use of the within party variation in outcomes. We estimate a non-linear proba-bility model and we create counterfactuals to conclude that ballot design not only may have changed the electoral results but also has a greater importance than candidates’ ideology, education, experience and party affiliation.

description: We have detected narrow HI 21cm and CI absorption at $z \sim 1.4 - 1.6$ towards Q0458$-$020 and Q2337$-$011, and use these lines to test for possible changes in the fine structure constant $α$, the proton-electron mass ratio $μ$, and the proton gyromagnetic ratio $g_p$. A comparison between the HI 21cm and CI line redshifts yields $ΔX/X = [+6.8 \pm 1.0] \times 10^{-6}$ over $0 < \le 1.46$, where $X = g_p α^2/μ$, and the errors are purely statistical, from the gaussian fits. The simple line profiles and the high sensitivity of the spectra imply that statistical errors in this comparison are an order of magnitude lower than in previous studies. Further, the CI lines arise in cold neutral gas that also gives rise to HI 21cm absorption, and both background quasars are core-dominated, reducing the likelihood of systematic errors due to local velocity offsets between the hyperfine and resonance lines. The dominant source of systematic error lies in the absolute wavelength calibration of the optical spectra, which appears uncertain to $\sim 2$ km/s, yielding a maximum error in $ΔX/X$ of $\sim 6.7 \times 10^{-6}$. Including this, we obtain $ΔX/X = [+6.8 \pm 1.0 (statistical) \pm 6.7 (max. systematic)] \times 10^{-6}$ over $0 < \le 1.46$. Using literature constraints on $Δμ/μ$, this is inconsistent with claims of a smaller value of $α$ from the many-multiplet method, unless fractional changes in $g_p$ are larger than those in $α$ and $μ$.

description: The short--time self diffusion coefficient of a sphere in a suspension of rigid rods is calculated in first order in the rod volume fraction. For low rod concentrations the correction to the Einstein diffusion constant of the sphere is a linear function of the rod volume fraction with the slope proportional to the equilibrium averaged mobility diminution trace of the sphere interacting with a single freely translating and rotating rod. The two--body hydrodynamic interactions are calculated using the so--called bead model in which the rod is replaced by a stiff linear chain of touching spheres. The interactions between spheres are calculated numerically using the multipole method. Also an analytical expression for the diffusion coefficient as a function of the rod aspect ratio is derived in the limit of very long rods. We show that in this limit the correction to the Einstein diffusion constant does not depend on the size of the tracer sphere. The higher order corrections depending on the applied model are computed numerically. An approximate expression is provided, valid for a wide range of aspect ratios.

description: Nonresponse is common in surveys. When the response probability of a survey variable $Y$ depends on $Y$ through an observed auxiliary categorical variable $Z$ (i.e., the response probability of $Y$ is conditionally independent of $Y$ given $Z$), a simple method often used in practice is to use $Z$ categories as imputation cells and construct estimators by imputing nonrespondents or reweighting respondents within each imputation cell. This simple method, however, is inefficient when some $Z$ categories have small sizes and ad hoc methods are often applied to collapse small imputation cells. Assuming a parametric model on the conditional probability of $Z$ given $Y$ and a nonparametric model on the distribution of $Y$, we develop a pseudo empirical likelihood method to provide more efficient survey estimators. Our method avoids any ad hoc collapsing small $Z$ categories, since reweighting or imputation is done across $Z$ categories. Asymptotic distributions for estimators of population means based on the pseudo empirical likelihood method are derived. For variance estimation, we consider a bootstrap procedure and its consistency is established. Some simulation results are provided to assess the finite sample performance of the proposed estimators.

Navigating shifts in power : prospect theory and the evolution of US relations with China and Japan
Creators: name: Gasmi, Mohamed
Publisher: name: University of British Columbia
Year: 2023

description: Why does a hegemon abruptly transition its stance toward certain powers from cooperation to confrontation? Using the example of U.S.-China and U.S.-Japan relations, I argue that, for a hegemon, changing state dispositions are not predominantly about military strength, ideology, nor adherence to global norms. Instead, drawing upon prospect theory, I suggest an economic and behavioral reasoning. I argue the United States’ contradictory actions are better understood as decisions made following transitions from a “domain of gain” to a “domain of loss,” spurred by economic disruptions to the status quo. To test this assertion, I use the synthetic control method to simulate a counterfactual path for China and Japan – their expected outcome had they never reached key economic thresholds. I find that the 35 to 40 percent range of proportional GDP relative to the United States coincides with a significant increase in negative sentiment, across different measures. This suggests there are important psychological considerations influencing state behavior, factors which traditional theories of international relations overlook.

description: Theories of party systems suggest that more restrictive rules should lead to fewer parties. According to this line of reasoning, parties and voters should strategically respond to reforms in electoral rules, such as changes in district magnitude. That is, a decrease in district magnitude should decrease the size of the party system, whereas an increase in magnitude should enlarge the party system. Using a series of difference-in-differences models based on data from Brazilian municipalities before and after an exogenous reform in magnitude, I study the effects of this electoral reform on both electoral coordination and legislative fragmentation. Contrary to the expectation, the number of lists did not change after a decrease in magnitude. However, parties formed more pre-electoral coalitions in municipalities that lost seats. Voters also coalesced around fewer lists. Lastly, as expected, the reform produced a decrease in legislative fragmentation. Both mechanical and psychological effects were responsible for this modification in fragmentation.

description: We propose a model based on random dynamical systems (RDS) in information spaces (realized as rings of $p$-adic integers) which supports Buonomano's non-ergodic interpretation of quantum mechanics. In this model the memory system of an equipment works as a dynamical system perturbed by noise. Interference patterns correspond to attractors of RDS. There exists a large class of $p$-adic RDS for which interference patterns cannot be disturbed by noise. Therefore, if the equipment is described by such a RDS then the result of statistical experiment does not depend on noise in the equipment. On the one hand, we support the corpuscular model, because a quantum particle can be described as a corpuscular object. On the other hand, our model does not differ strongly from the wave model, because a quantum particle interacts with the whole equipment. Hence the interaction has nonlocal character. For example, in the two slit experiment a quantum particle interacts with both slits (but it passes only one of them).

description: A complete adiabatic transport of Bose-Einstein condensate in a double-well trap is investigated within the Landau-Zener (LZ) and Gaussian Landau-Zener (GLZ) schemes for the case of a small nonlinearity, when the atomic interaction is weaker than the coupling. The schemes use the constant (LZ) and time-dependent Gaussian (GLZ) couplings. The mean field calculations show that LZ and GLZ suggest essentially different transport dynamics. Significant deviations from the case of a strong coupling are discussed.

description: Instead of focusing on “why voters appear to tolerate rather than punish” as most previous literature, this paper advances an alternative explanation: it seeks to explain how voters process information about corruption. Consistent with research on public opinion formation, this paper argues that voters can perceive the same event and make different interpretation about its meaning. Based on an original survey experiment conducted during the 2018 presidential election in Mexico, this study finds that citizens hold partisan attitudes and are motivated to protect these partisan predispositions, which make them interpret common events in different way. In particular, when this study informed voters that an unnamed candidate engaged in corruption, respondents unequivocally considered such actions as corrupt. However, when the name of their co-partisan candidate was explicitly mentioned as engaging in the same activities, voters rejected to qualify them as corrupt. Partisans are not “tolerating” or “condoning” corruption; partisans tend to choose interpretations that rationalize their partisan priors and justify their co-partisans’ behavior.

description: This paper analyzes the thought process involved in problem solving and its categorization as creative thinking as defined by psychologist R. Weisberg (2006). Additionally, the notion of insight, sometimes present in unconscious creative thinking and often leading to creative ideas, is discussed in the context of geometry problem solving. In particular, it is argued that solving insight problems used by psychologists to measure creativity and solving certain geometry problems share similar thought processes.

Experimental results are compared with those from a theoretical model developed for pulsed pumping with a Gaussian transverse profile. The results allow to tailor the shape of correlation area of the signal and idler photons using pump-field and crystal parameters. As an example, splitting of a correlation area caused by a two-peak pump-field spectrum is experimentally studied.

description: This article focuses on the mathematical value of teaching angles through the use of sundials in the classroom. The history of sundials and the mathematics embedded within them is discussed in detail. In addition, practical applications of angles are included, along with interactive practice telling time with the angles created on sundials. Time as a whole is explored from historical, mathematical and technological perspectives. Further, connections to middle and secondary grade mathematics, practical applications, and technological tools that aid student understanding are discussed. Teaching the history of tracking time through the study of sundials provides a rich learning experience for students in the middle grades; they are able to see mathematical concepts, such as angles applied to the real world, as well as learn new history about a topic they most likely are not very familiar with.

description: We introduce a semiparametric ``tubular neighborhood'' of a parametric model in the multinomial setting. It consists of all multinomial distributions lying in a distance-based neighborhood of the parametric model of interest. Fitting such a tubular model allows one to use a parametric model while treating it as an approximation to the true distribution. In this paper, the Kullback--Leibler distance is used to build the tubular region. Based on this idea one can define the distance between the true multinomial distribution and the parametric model to be the index of fit. The paper develops a likelihood ratio test procedure for testing the magnitude of the index. A semiparametric bootstrap method is implemented to better approximate the distribution of the LRT statistic. The approximation permits more accurate construction of a lower confidence limit for the model fitting index.

p-adic probability prediction of correlations between particles in the two-slit and neutron interferometry experiments

Subjects: subject: Mathematical Physics (math-ph)

description: We start from Feynman`s idea to use negative probabilities to describe the two slit experiment and other quantum interfernce experiments. Formally by using negative probability distributions we can explain the results of the two slit experiment on the basis of the pure corpuscular picture of quantum mechnanics. However, negative probabilities are absurd objects in the framework of the standard Kolmogorov theory of probability. We present a large class of non-Kolmogorovean probability models where negative probabilities are well defined on the frequency basis. These are models with probabilities which belong to the so-called field of $p$-adic numbers. However, these models are characterized by correlations between trails. Therefore, we predict correlations between particles in interference experiments. In fact, our predictions are similar to the predictions of the so-called nonergodic interpretation of quantum mechanics, which was proposed by V. Buonomano. We propose the concrete experiments (in particular, in the framework of the neutron interferometry) to verify our predictions on the correlations.

Although part of a study conducted to investigate the effects of journal writing on academically lower-achieving learners with English as their second language, this paper will focus only on the students’ perceptions of writing journals in mathematics. The students’ perceptions are based on their experience from a 2-cycle action research study. A total of 35 students, ranging from age 15 to 16 years old, from two Grade 10 classes were involved in the study. Data from the student journal entries and questionnaires revealed that the majority of students found journal writing beneficial for the development of their mathematical learning.

description: The rise of employment insecurities has led to concerns about its impact on young workers in Europe. This chapter examines how recruiters in Bulgaria and Switzerland interpret employment insecurities in young job-seekers’ applications. Drawing from the societal analysis framework, the authors argue that the coordination of education and employment in both countries affects the way employment insecurities are assessed by recruiters when hiring for skilled jobs. Using qualitative content analysis of open-ended questions from the NEGOTIATE Employer Survey, the authors investigate how recruiters perceive job-hopping and unemployment as labour market signals. The results suggest that in both countries unemployment is mainly seen as a problem of the person. However, in Switzerland, recruiters more frequently attribute problems with job-hopping to the company, whereas in Bulgaria they more often refer to the person. Thus, job-hopping seems to be a more legitimate career strategy for young workers in the Swiss labour market.

description: Considerable evidence suggests that social diversity increases the number of political parties. While a vast literature examines this relationship by measuring social diversity as ethnic fragmentation, the convenience of capturing the level of social heterogeneity by using alternative indicators has been traditionally overlooked. In this article, I offer new evidence that documents the impact of social diversity on party system size by proxying the former as the number of social classes. Using both objective class positions and subjective class identifications and employing two different datasets that cover democratic legislative elections around the world between 1981 and 2015, I find that the effective number of social classes has a positive effect on party system fragmentation when the average district magnitude in a democracy is high. Given the difficulty to test these effects in a cross-country environment net of unobserved heterogeneity, I examine the robustness of the findings in Spain between 2000 and 2016, an ideal case due to large differences in district magnitude and a changing party system. Overall, the results suggest that high levels of social diversity are likely to increase party system fragmentation when the electoral system is permissive enough.
An analysis of the effectiveness of a commercial hospital artificial intelligence system in reducing readmissions in high-risk medicare patients

Year: 2022

description: Readmission within 30 days of hospital discharge and avoidable emergency room (ED) visits have shown to result in an overall increase in healthcare cost and increased risk to patients. Evolving payment models under the ACA focus on reducing unnecessary costs and decreasing short-term readmissions for Medicare patients with common comorbidities. Recent artificial intelligence (AI) models may have the potential to help care coordination team members accurately identify high-risk patients electronically and embed that application within their clinical workflow. This research aimed to evaluate the use of the artificial intelligence-based application in a standalone webform to reduce unplanned 30 days hospital readmissions and unnecessary ED utilization.A commercial vendor AI application was implemented in an enterprise health system in a large metropolitan area between October 2019 and February 2020 that assessed all Medicare admitted patients to 10 major hospitals and generated interventions intended to reduce unplanned 30 days readmissions at those hospitals. In addition, readmission rate change was evaluated for the same hospitals compared with a five months pre-implementation period of a similar population.Over five months post-implementation, 30 days ED re-visits decreased from 7.7% to 6.5% (p <0.001), and readmission rate decreased from 15.7% to 13% (p <0.001) with 7% absolute risk reduction and 21% relative risk reduction among the high-risk subgroup of patients based on AI application risk stratification algorithm with the number needed to treat to avoid one readmission of 15 for that subgroup. This study may provide valuable insight into creating proper models of population health risk stratification electronic tools by combining risk identification and tailored interventions to that population and establishing best practices for future implementations of AI in population health.

description: We propose an adaptive independent Metropolis--Hastings algorithm with the ability to learn from all previous proposals in the chain except the current location. It is an extension of the independent Metropolis--Hastings algorithm. Convergence is proved provided a strong Doeblin condition is satisfied, which essentially requires that all the proposal functions have uniformly heavier tails than the stationary distribution. The proof also holds if proposals depending on the current state are used intermittently, provided the information from these iterations is not used for adaption. The algorithm gives samples from the exact distribution within a finite number of iterations with probability arbitrarily close to 1. The algorithm is particularly useful when a large number of samples from the same distribution is necessary, like in Bayesian estimation, and in CPU intensive applications like, for example, in inverse problems and optimization.

Thinking in Patterns to Solve Multiplication, Division, and Fraction Problems in Second Grade
Creators: name: Stokes, Patricia
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2016

description: Experts think in patterns and structures using the specific “language” of their domains. For mathematicians, these patterns and structures are represented by numbers, symbols and their relationships (Stokes, 2014a). To determine whether elementary students in the United States could learn to think in mathematical patterns to solve addition and subtraction, a pilot curriculum using an Asian model of base-10 counting was introduced in kindergarten and first grade. Children in the pilot program, like their Asian counterparts, did not appear to have any difficulty with the concept of place value. They also did not have significant difficulties with single- and double-digit addition and subtraction as is often the case with American students (Stokes, 2010, 2013, 2014a, 2014b). To continue the pattern-based process in second grade, a Multi-Operation Chart was designed to make the relationships between multiplication, division and fractions clear. Testing at the end of the school year showed that students not only met, but exceeded the Standards set by the Common Core standards for second grade. Medians and modes for correct single- and double-digit multiplication, single-digit division and fractions were 100%. Educational implications are offered and discussed.

description: Abstract
The objective of this study is to investigate the influence of information technology capability on knowledge management capability, the influence of information technology capability on organisational performance, the influence of knowledge management capability on organisational performance, and the indirect impact of information technology capability on organisational performance through knowledge management capability in PT. "XXX" Pharma, Tbk. The research is based on the understanding of the interconnectedness between information technology cap. The present study utilised a quantitative approach, employing both explanatory and survey methodologies. The process of data collection involved the distribution of a questionnaire to a sample of 44 respondents, which was selected using the purposive random sampling technique. The data processing was performed using route analysis, utilising the IBM Predictive Analytic Software (PASW) version 24. The empirical evidence suggests a statistically significant and positive correlation between the capability of information technology and the capability of knowledge management.

description: The determination of pulsation velocities from observed spectra of Cepheids is needed for the Baade-Wesselink calibration of these primary distance markers. The applicability of the Fourier-disentangling technique for the determination of pulsation velocities of Cepheids and other pulsating stars is studied. The KOREL-code was modified to enable fitting of free parameters of a prescribed line-profile broadening function corresponding to the radial pulsations of the stellar atmosphere. It was applied to spectra of delta Cep in the H-alpha region observed with the Ondrejov 2-m telescope. The telluric lines were removed using template-constrained disentangling, phase-locked variations of line-strengths were measured and the curves of pulsational velocities obtained for several spectral lines. It is shown that the amplitude and phase of the velocities and line-strength variations depend on the depth of line formation and the excitation potential. The disentangling of pulsations in the Cepheid spectra may be used for distance determination.

title: Mise en Abyme: Immersive performance and composition practices through interdisciplinarity, collaboration and music technology.
Creators: name: Mannion, Ruaidhri
Publisher: name: Royal College of Music
Year: 2019

description: This doctoral portfolio and commentary thesis constitute a practice-led research into ‘immersive’ musical experiences, both from the perspective of the spectator and the composer. Specific parallels are drawn between immersive experiences, the concept of ‘mise-en-abyme’ (placing copies of an image within the same image, or placing a story within a story) and how this concept can be developed as a process for creating musical materials. Interdisciplinary art forms, collaborative methods and the novel approaches to using multimedia tools are explored for their potential in creating conditions for engaged listening and composition techniques.

After an introduction to the ‘mise-en-abyme’ concept in Chapter One, the main body of the commentary thesis is divided into three main sections (Chapters Two, Three and Four). The first part (Chapter Two) explores specific musical devices that draw on installation art forms to provoke heightened experience of musical works. The second part (Chapter Three) explores two major collaborative projects, investigating detailed working methods, the role of the composer-performer and the evolving role of authorship in modern music making. The third part (Chapter Four) explores new methods of composing with digital media, that draw on the ‘mise-en-abyme’ concept as a process for generating new materials and musical structures.

This is accompanied by a portfolio of eleven original works for acoustic instruments and electroacoustic media. Scores, audio and video recordings, digital performance materials (Max patches and Ableton Live sessions) and an appendix of supplementary materials are included in print form and on an accompanying USB flash drive.
DESY Beamer-Style - 2022 edition

Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2022

description: The included ZIP holds an adoption of DESY 2022 corporate design for presentations build in LaTeX using Beamer. It is assumed, that documents are processed using `lualatex`, which is available in current editions of TeXLive. These days this is the default TeX installation on most Linux platforms, it is pre installed on all DESY Linux Workstations as well as in the DESY TeX setup for other platforms. The zip is meant to be self contained. For general usage, just copy the contents of the Talk/-folder to a new folder (one folder per talk) and just edit away there. Basically, building a talk is editing two files: `metadata.tex` holds all all metadata like your name, title of talk, date, keywords, abstract and so on. `Talk.tex` is the actual talk. Please follow the included README.md (plain text file) for more detailed instructions.**Note** the default font for DESY presentations is `Arial`. On Linux you may need to install ttf-mscorefonts (non-free) manually.
Experimental investigation of force and geometrycal factors in pin engagement of drive sprockets and rubber-reinforced tracks of transport-technologycal vehicle

description: The wide distribution of rubber-reinforced tracks requires a revision of the basic principles of drive sprockets designing, their teeth and gearing, to ensure the best life of the elements of the tracked gear and the quality of the pin engagement itself. The formula for determining the dependence of geometric parameters of the engagement according to force, which provides no slip in the engagement are given. A method for determining the range of optimal geometric parameters of an engagement is shown using this dependence, in which there is no slip in the engagement when the spool moves along a spanning arc using the example of a specific undercarriage system. Experimentally confirmed the adequacy and reliability of theoretical provisions.

description: Do voters update their racialized political preferences in response to new information? To answer this long-standing question, we conduct an original survey examining U.S. mainland attitudes toward towards Puerto Rican statehood, a rare consequential racialized issue of low salience. To test whether public support for statehood can be changed, we embedded an information experiment describing Puerto Rico’s political status and its relationship to the U.S. The treatment was designed to increase the perceived connection between the groups through effortful thinking. Descriptively, our results indicate that Americans are generally ambivalent to the idea of Puerto Rico becoming the 51st state. We further find that opposition to statehood is related to anti-immigration attitudes, conservative ideology, and lack of knowledge about the issue. Nonetheless, we also show that highly racialized opposition to statehood can be significantly decreased among all groups of voters by providing simple background information on U.S. and Puerto Rico’s relationship.

description: The transition from large centralized complex control systems to distributed configurations that rely on a network of a very large number of interconnected simpler subsystems is ongoing and inevitable in many applications. It is attributed to the quest for resilience, flexibility, and scalability in a multitude of engineering fields with far-reaching societal impact. Although many design methods for distributed and decentralized control systems are available, most of them rely on a centralized design procedure requiring some form of global information of the whole system. Clearly, beyond a certain scale of the network, these centralized design procedures for distributed controllers are no longer feasible and we refer to the corresponding systems as ultra large-scale systems (ULSS). For these ULSS, design algorithms are needed that are distributed themselves among the subsystems and are subject to stringent requirements regarding communication, computation, and memory usage of each subsystem. In this paper, a set of requirements is provided that assures a feasible real-time implementation of all phases of a control solution on an ultra large scale. State-of-the-art approaches are reviewed in the light of these requirements and the challenges hampering the development of befitting control algorithms are pinpointed. Comparing the challenges with the current progress leads to the identification and motivation of promising research directions.

Assessment of a Problem Posing Task in a Jamaican Grade Four Mathematics Classroom
Creators: name: Munroe, Kayan Lloyd
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2016

description: This paper analyzes how a teacher of mathematics used problem posing in the assessment of the cognitive development of 26 students at the grade-four level. The students, ages 8 to 10 years, were from a rural elementary school in western Jamaica. Using a picture as a prompt, students were asked to generate three arithmetic problems and to offer their solution to one of these problems. The teacher used both formative and summative assessments to evaluate students’ levels of cognition in mathematics. Formative assessment revealed that some students’ mathematical ability were higher than their reading ability. Summative assessment showed that more advanced students generated more complex questions. The teacher was able to use the information gathered from the problem posing activity to create better lesson plans for the class.

description: International rankings show children in the United States perform well below average in mathematics. There are also large mathematics achievement gaps between children of lower- and higher-socioeconomic status. As today’s teachers face these challenges, they are also faced with the pressures of sweeping educational reforms that arrived with the adoption of No Child Left Behind and continue into the Common Core State Standards era. These strict standards and the implications of low-performance can easily push teachers and parents towards the belief that direct instruction is the only way to help children learn effectively. In this article, we review evidence from the literature about playful learning as an alternative and powerful pedagogical approach. We apply the principles of playful learning to specific state standards for mathematics and illustrate promising ways to improve mathematics learning in the classroom.
