title: Single-Route and Dual-Route Approaches to Reading Aloud Difficulties Associated with Dysphasia.
Creators: name: Mack, Siobhan Kathryn
Publisher: name: The Open University
Year: 2000

description: The study of reading aloud is currently informed by two main types of theory: modular dual-route and connectionist single-route. One difference between the theories is the type of word classification system which they favour. Dual-route theory employs the regular-irregular dichotomy of classification, whereas single route considers body neighbourhoods to be a more informative approach. This thesis explores the reading aloud performance of a group of people with dysphasia from the two theoretical standpoints by employing a specifically prepared set of real and pseudoword stimuli. As well as being classified according to regularity and body neighbourhood, all the real word stimuli were controlled for frequency. The pseudowords were divided into two groups, common pseudowords and pseudohomophones, and classified according to body neighbourhood.

 There were two main phases to the study. In the first phase, the stimuli were piloted and the response time performances of a group of people with dysphasia and a group of matched control people were compared. In the second phase, a series of tasks was developed to investigate which means of word classification best explained the visual lexical decision and reading aloud performance of people with dysphasia. The influence of word knowledge was also considered.

 The data was analysed both quantitatively and qualitatively. The quantitative analysis of the number of errors made indicated that classification of items by body neighbourhood and frequency provided the more comprehensive explanation of the data. Investigation of the types of errors that were made did not find a significant relationship between word type and error type, but again the results indicated that the influence of frequency and body neighbourhood was stronger than that of regularity. The findings are discussed both in terms of their implications for the two theories of reading aloud and their relevance to clinical practice.

description: We present a method to invert a given density and find the Kohn-Sham (KS) potential in Density Functional Theory (DFT) which shares that density. Our method employs the concept of screening density, which is naturally constrained by the inversion procedure and thus ensures the density being inverted leads to a smooth KS potential with correct asymptotic behaviour. We demonstrate the applicability of our method by inverting both local (LDA) and non-local (Hartree-Fock and Coupled Cluster) densities; we also show how the method can be used to mitigate the effects of self-interactions in common DFT potentials with appropriate constraints on the screening density.

description: The study describes the experience of introducing three intensity levels of parent participation in three third-grade classes for science instruction using Playtime is Science; an equity curriculum that utilizes parent participation. The study sought to determine the optimum level of participation by ascertaining the most influential aspect of involvement on proficiency scores and the most important aspect of involvement to participants. The levels of participation intensity were distinguished by: (1) the number of parents in the classroom; (2) the responsibilities of the parents; (3) the training received; and (4) the number of students with whom the parents worked. Involvement at each level would potentially manifest aspects of role modeling, lowered student-to-adult instructional ratio, and parent expertise to varying degrees. The three levels of participation were introduced during explorations in three Playtime is Science units following a rotation schedule. Student proficiency was assessed through scores on pre- and post-tests, journals, and discourse. ANCOVA was used to identify main and interaction effects of the independent variables (class, unit and level) on student proficiency taking into account existing differences in groups. Participant attitudes were assessed through journals and interviews. Observations of explorations triangulated findings and assessed participant interactions. Field notes, transcripts and photographs were coded according to the aspects of parent involvement. The results showed level of parent intensity of involvement had no affect on proficiency scores. Therefore, no aspect of parent involvement was determined to be the most influential. Participants felt that lowered instructional ratio and role modeling were the most important aspects of involvement. The level of involvement that utilized the lowest ratio and the most role modeling was level III, small group facilitators. Level III was recognized as the optimum level of participation in science instruction for this study. Although no level of involvement was significantly influential for student scores, there was a main effect for units, supporting the finding that teacher conceptions of science are more influential on student proficiency than parent participation at any level. The influence of teacher conceptions was unanticipated but is critical to consider when implementing any program or methodology to improve science instruction.

description: Eighty-six undergraduate and graduate university students with previously diagnosed learning disabilities (LD's) were asked to rate their willingness to seek help from formal academic services in response to two different experimental manipulations. Students were presented with hypothetical situations in which they were asked to imagine that they were making a request for help; these situations varied in valence (positive vs. negative response to the request) and in respondent to the request (professor vs. peer). Students reported the most willingness to seek help after reading about a positive reaction from a professor and the least willingness to seek help in response to a professor's negative reaction. Two hypothetical radio advertisements that varied in type of motivational goal emphasized (learning vs. performance) were also presented; students reported somewhat more willingness to seek help in response to the advertisement emphasizing performance goals. Students who viewed their LD's as more stigmatizing, nonmodifiable, and global were less likely than students with more neutral or positive views of their LD's to report willingness to seek help in response to negative situations and also had lower overall self-esteem. Previous experiences with help-seeking appeared to affect willingness to seek help only in response to the performance goals advertisement. No gender differences in help-seeking were found in the present study. A relationship between time of diagnosis and willingness to seek help was found only for the positive situations. Views of one's LD and having used academic services were not found to be related. Implications for intervention with these students, limitations of the present study, and suggestions for future research are discussed.
Orbital and magnetic transitions in geometrically-frustrated vanadium spinels -- Monte Carlo study of an effective spin-orbital-lattice coupled model --

description: We present our theoretical and numerical results on thermodynamic properties and the microscopic mechanism of two successive transitions in vanadium spinel oxides $A$V$_2$O$_4$ ($A$=Zn, Mg, or Cd) obtained by Monte Carlo calculations of an effective spin-orbital-lattice model in the strong correlation limit. Geometrical frustration in the pyrochlore lattice structure of V cations suppresses development of spin and orbital correlations, however, we find that the model exhibits two transitions at low temperatures. First, a discontinuous transition occurs with an orbital ordering assisted by the tetragonal Jahn-Teller distortion. The orbital order reduces the frustration in spin exchange interactions, and induces antiferromagnetic correlations in one-dimensional chains lying in the perpendicular planes to the tetragonal distortion. Secondly, at a lower temperature, a three-dimensional antiferromagnetic order sets in continuously, which is stabilized by the third-neighbor interaction among the one-dimensional antiferromagnetic chains. Thermal fluctuations are crucial to stabilize the collinear magnetic state by the order-by-disorder mechanism. The results well reproduce the experimental data such as transition temperatures, temperature dependence of the magnetic susceptibility, changes of the entropy at the transitions, and the magnetic ordering structure at low temperatures. Quantum fluctuation effect is also examined by the linear spin wave theory at zero temperature. The staggered moment in the ground state is found to be considerably reduced from saturated value, and reasonably agrees with the experimental data.

description: Background: Cardiovascular disease (CVD) remains the leading cause of death in American women, but CVD knowledge and risk perception in women is declining. Little is known about how young women of reproductive age perceive their risk of CVD or if risk perception varies based on experience of adverse pregnancy outcomes (APO). The objective of this study was to determine whether women who have experienced an APO have a greater awareness of personal risk factors for CVD compared with women with uncomplicated pregnancies.Methods and Results: A self-administered online survey was distributed to 5,612 women who gave birth at an urban medical center between January 1 and July 1, 2020. Of 714 respondents, 182 (25%) reported experiencing an APO, which was defined as self-report of hypertensive disorders of pregnancy (HDP), gestational diabetes mellitus (GDM), preterm birth, or a low birth weight infant. There was no significant difference in CVD knowledge scores between womenwho reported experiencing an APO and women with uncomplicated pregnancies (p= 0.51), and similar proportions of women in both groups (62%) identified CVD as the leading cause of death in women. Most women associated HDP (81%) and GDM (82%) with CVD risk, while few recognized preterm birth (13%) or low birth weight (11%) as CVD risk factors. Women who experienced an APO reported higher perception of risk for future CVD (adjusted odds ratio, 2.64[95% CI 1.83-3.80]) in comparison to women with uncomplicated pregnancies. However, half of women who experienced an APO reported average or below average risk for CVD, and only 41 (22.5%) reported speaking with a healthcare professional about CVD within the past year.Conclusions: The women in our sample were generally well educated about CVD risk factors, but significant gaps remain in the overall perception of personal CVD risk along with knowledge deficits related to a subset of pregnancy-related CVD risk factors and CVD mortality in women.

description: Coverage path planning (CPP) is the task of designing a trajectory that enables a mobile agent to travel over every point of an area of interest. We propose a new method to control an unmanned aerial vehicle (UAV) carrying a camera on a CPP mission with random start positions and multiple options for landing positions in an environment containing no-fly zones. While numerous approaches have been proposed to solve similar CPP problems, we leverage end-to-end reinforcement learning (RL) to learn a control policy that generalizes over varying power constraints for the UAV. Despite recent improvements in battery technology, the maximum flying range of small UAVs is still a severe constraint, which is exacerbated by variations in the UAV's power consumption that are hard to predict. By using map-like input channels to feed spatial information through convolutional network layers to the agent, we are able to train a double deep Q-network (DDQN) to make control decisions for the UAV, balancing limited power budget and coverage goal. The proposed method can be applied to a wide variety of environments and harmonizes complex goal structures with system constraints.

title: Aspects of Nonlinearity and Dissipation in Magnetohydrodynamics
Creators: name: Verwichte, Erwin André Omer
Publisher: name: The Open University
Year: 2000

description: We investigate two projects: (i) the weakly nonlinear evolution of two oppositely travelling waves and (ii) the dissipative instability of a tangential discontinuity.

 We show that the ponderomotive force is a basic nonlinear force, which is, to leading-order, proportional to the product of a wave quantity and a gradient of a wave quantity. The ponderomotive force of Alfvén waves corresponds to a magnetic wave pressure force.

 The motion of beads on a string and the fluid motions in an oscillating tube are shown to be good mechanical analogues for the weakly nonlinear evolution of bounded Alfvén waves, especially in plasmas with a low plasma β.

 We examine, analytically and numerically, the weakly nonlinear evolution of bounded fast magneto-acoustic waves in the cold plasma limit and show that the ponderomotive force moves plasma along the equilibrium magnetic field. The maximum density enhancement is proportional to α2/β, with α the wave amplitude and β of the order of the plasma β, We obtain the wave amplitude and frequency modulation and discuss the problems with the cold-plasma assumption.

 The weakly nonlinear interaction of Alfvén pulses is investigated in the cold-plasma limit and for finite-β plasmas. We find excellent agreement between analytical and numerical results. We describe a density enhancement, maximally of order α2β1/2 at the position of Alfvén pulse excitation, which splits into two slow pulses, We describe the shock-formation of the Alfvén and slow pulses.

 The dissipative instability of the tangential discontinuity is examined and applied to coronal hole boundaries. We derive a dispersion relation, which includes weak viscosity and thermal conduction, and is solved for a specific model, using perturbation theory. The effect of viscosity and thermal conduction on stability are discussed, It is shown that dissipation lowers the threshold flow speed for instability.

description: Let $W$ be a group endowed with a finite set $S$ of generators. A representation $(V,ρ)$ of $W$ is called a reflection representation of $(W,S)$ if $ρ(s)$ is a (generalized) reflection on $V$ for each generator $s \in S$. In this paper, we prove that for any irreducible reflection representation $V$, all the exterior powers $\bigwedge ^d V$, $d = 0, 1, \dots, \dim V$, are irreducible $W$-modules, and they are non-isomorphic to each other. This extends a theorem of R. Steinberg which is stated for Euclidean reflection groups. Moreover, we prove that the exterior powers (except for the 0th and the highest power) of two non-isomorphic reflection representations always give non-isomorphic $W$-modules. This allows us to construct numerous pairwise non-isomorphic irreducible representations for such groups, especially for Coxeter groups.

How Important is Money in the Conduct of Monetary Policy?

description: I consider some of the leading arguments for assigning an important role to tracking the growth of monetary aggregates when making decisions about monetary policy. First, I consider whether ignoring money means returning to the conceptual framework that allowed the high inflation of the 1970s. Second, I consider whether models of inflation determination with no role for money are incomplete, or inconsistent with elementary economic principles. Third, I consider the implications for monetary policy strategy of the empirical evidence for a long-run relationship between money growth and inflation. (Here I give particular attention to the implications of “two-pillar Phillips curves” of the kind proposed by Gerlach (2003).) And fourth, I consider reasons why a monetary policy strategy based solely on short-run inflation forecasts derived from a Phillips curve may not be a reliable way of controlling inflation. I argue that none of these considerations provide a compelling reason to assign a prominent role to monetary aggregates in the conduct of monetary policy.

description: A series of exact BPS solutions are found for single and double domain walls in N=2 supersymmetric (SUSY) QED for finite gauge coupling constants. Vector fields are found to be massive, although it is localized on the wall. Massless modes can be assembled into a chiral scalar multiplet of the preserved N=1 SUSY, after an appropriate gauge choice. The low-energy effective Lagrangian for the massless fields is obtained for the finite gauge coupling. The inter-wall force is found to be much stronger than the known infinite coupling case. The previously proposed expansion in inverse powers of the gauge coupling has pathological oscillations, and does not converge to the correct finite coupling result.

The role of motivation in government reform: A comparative analysis of executives in the public, nonprofit, and for -profit sectors
Creators: name: Malone, Patrick Shawn
Publisher: name: American University
Year: 2023

description: In recent and past governmental reform efforts, private business sector values of economy, efficiency, and productivity collide with more traditional public sector values such as equity, duty, and patriotism. But despite well-established literature on the public/private distinction, we still know very little about individual executives, their motivation, congruence with their organization's values, and their job satisfaction. This study draws from the theoretical bases of organizational behavior, organizational theory, public administration, and management to examine the differences among these executives. This research advances work done in previous studies in numerous ways. First, unlike earlier efforts, this exploration incorporates a cross-sector comparison of personal value structures as correlated with the individual's perception of their organization's values. This inquiry also attempts to determine the differences among, and the correlations between, multiple measures of motivation, personal and organizational values (organizational fit), and job satisfaction within the sector where the executive currently works. If there are indeed differences among executives, we should expect to see marked discrepancies in their motivations, value congruency with their organizations, and levels of job satisfaction. The cohort population for this research is comprised of chief executive officers in the public, nonprofit, and for-profit sectors of US hospitals. Survey recipients are drawn from a simple random sample of hospitals from the American Hospital Association Guide to the Health Care Field - 1998--99 Edition. The final return rate was 33.3%. Results indicate significant differences in job satisfaction levels, intrinsic and extrinsic motivators, and selected measures of organizational value congruence. Sector preference and overall value congruence were strong for all sectors. Finally, public sector executives showed statistically higher levels of motivation for most public service related variables. The findings suggest we are at a critical point with government reform. Even though the prospect of entrepreneurialism in government reform, along with its link to the private sector, offers exciting opportunities for the government, it offers challenges as well. Care must be taken by reformers to recognize the differences in motives and needs of those with whom they enjoin to serve the public.

description: The decay timescales of the quasinormal modes of a massive scalar field have an intriguing behavior: they either grow or decay with increasing angular harmonic numbers $\ell$, depending on whether the mass of the scalar field is small or large. We identify the properties of the effective potential of the scalar field that leads to this behavior and characterize it in detail. If the scalar field is non-minimally coupled, considered here, the scalar quasinormal modes will leak into the gravitational wave signal and will have decaying times that are comparable or smaller than those typical in General Relativity. Hence, these modes could be detectable in the future. Finally, we find that the anomalous behavior in the decay timescales of quasinormal modes is present in a much larger class of models beyond a simple massive scalar field.

description: As Canada increasingly structures itself towards a “knowledge based economy”, the supply of high-skilled professionals such as engineers and other science graduates acquires more importance. Following the theoretical framework developed by Ryoo and Rosen (2004), we develop and estimate a dynamic supply and demand model for engineers and scientists in Canada. We find that the estimated stock-flow dynamics are supportive of the theoretical model. The relative employment of engineers is quite sensitive to research and development (R&D) expenditures as a fraction of GDP, particularly after 1997. We then use the estimates to develop a dynamic impulse response function. Looking at the impact of a permanent increase in allocation towards R&D, we find that the adjustment process is relatively smooth and the market adjusts in about 2 to 8 years (plus the four years of natural lag in production) to within 80% of the final steady state. For a one-time improvement in R&D allocation, we find that under rational expectations, there is an initial increase in the number of science graduates, but then it falls to below the steady state value and remains there for a long period as the initial increase works its way through the market.

description: The nonlinear processes of frequency conversion like second harmonic generation (SHG) usually obey certain selection rules, resulting from the preservation of different kind of physical quantities, e.g., the angular momentum. For SHG created by monolayer of transition-metal dichalcogenides (TMDCs) like WS2, the valley-exciton locked selection rule predicts an SHG signal in the cross-polarization state. By combining plasmonic nanostructures with a monolayer of TMDC, a hybrid metasurface is realized which affects this nonlinear process due to an additional polarization conversion process. Here, we observe that the plasmonic metasurface modifies the light-matter interaction with the TMDC resulting in an SHG signal that is co-polarized with respect to the incident field, which is usually forbidden for solely monolayers of TMDC. We fabricate such hybrid metasurfaces by placing plasmonic nanorods on top of a monolayer WS2 and study the valley-exciton locked SHG emission from such system for different parameters, such as wavelength and polarization. Furthermore, we show the potential of the hybrid metasurface for tailoring nonlinear processes by adding additional phase information to the SHG signal using the Pancharatnam-Berry phase effect. This allows direct tailoring of the SHG emission to the far-field.

description: This paper shows that a new trade-o arises in the optimal contract when contracting takes place with vague information (objective ambiguity), re ecting that real-world contracting often takes place under imprecise information. The choicetheoretic framework captures a decision-maker's attitude towards vagueness by his optimism. The new trade-o is between (a) incentive provision and (b) exploitation of heterogeneity that arises endogenously because of the vague environment. Consequently, the optimal contract may distort eort in order to relax incentive compatibility and fully exploit the endogenously created heterogeneity, even when the agent is risk neutral and there is no insurance need in the relationship.

description: In 1999, J.C. Mattingly and Ya. G. Sinai used elementary methods to prove the existence and uniqueness of smooth solutions to the 2D Navier-Stokes equations with periodic boundary conditions. And they were almost successful in proving the existence and uniqueness of smooth solutions to the 3D Navier-Stokes equations using the same strategy. In this paper, we modify their technique to obtain a simpler proof of one of their results. We also argue that there is no logical reason why the 3D Navier-Stokes equations must always have solutions, even when the initial velocity vector field is smooth; if they do always have solutions, it is due to probability and not logic.

description: Complete colorings have the property that any two color classes has at least an edge between them. Parameters such as the Grundy, achromatic and pseudoachromatic numbers comes from complete colorings, with some additional requirement. In this paper, we estimate these numbers in the Kneser graph $K(n,k)$ for some values of $n$ and $k$. We give the exact value of the achromatic number of $K(n,2)$.

Violations of Bell inequalities as lower bounds on the communication cost of non-local correlations

Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: To reproduce in a local hidden variables theory correlations that violate Bell inequalities, communication must occur between the parties. We show that the amount of violation of a Bell inequality imposes a lower bound on the average communication needed to produce these correlations. Moreover, for every probability distribution there exists an optimal inequality for which the degree of violation gives the minimal average communication. As an example, to produce using classical resources the correlations that maximally violate the CHSH inequality, 0.4142 bits of communication are necessary and sufficient. For Bell tests performed on two entangled states of dimension d>=3 where each party has the choice between two measurements, our results suggest that more communication is needed to simulate outcomes obtained from certain non-maximally entangled states than maximally entangled ones.

description: Surfaces covered with layers of ultrathin nanoantenna structures, so-called metasurfaces, have recently been proven capable of completely controlling phase of light. Metalenses have emerged from the advance in the development of metasurfaces providing a new basis for recasting traditional lenses into thin, planar optical components capable of focusing light. The lens made of arrays of plasmonic gold nanorods were fabricated on a glass substrate by using electron beam lithography. A 1064 nm laser was used to create a high intensity circularly polarized light focal spot through metalens of focal length 800 $μ$m, $N.A. = 0.6$ fabricated based on Pancharatnam-Berry phase principle. We demonstrated that optical rotation of birefringent nematic liquid crystal droplets trapped in the laser beam was possible through this metalens. The rotation of birefringent droplets convinced that the optical trap possesses strong enough angular momentum of light from radiation of each nanostructure acting like a local half waveplate and introducing an orientation-dependent phase to light. Here, we show the success in creating a miniaturized and robust metalens based optical tweezers system capable of rotating liquid crystals droplets to imitate an optical motor for future lab-on-a-chip applications.

description: We present an empirical study of different social networks obtained from digital repositories. Our analysis reveals the community structure and provides a useful visualising technique. We investigate the scaling properties of the community size distribution, and that find all the networks exhibit power law scaling in the community size distributions with exponent either -0.5 or -1. Finally we find that the networks' community structure is topologically self-similar using the Horton-Strahler index.

description: The purpose of this dissertation was to explore the problem of transnational crime in the United States and determine if it is a significant threat to the United States and worthy of its own research agenda. It was found through a nationwide survey of 400 law enforcement agencies throughout the United States (228 respondents) that transnational criminal organizations were operational in the majority of these jurisdictions in 1999, (54 percent), and that these groups are involved in wide variety of illegal activities including drug trafficking, money laundering, high tech crime, financial fraud, and many other unlawful operations associated with organized crime. The police departments that reported active transnational criminal organizations in their jurisdictions in 1999 also expected these criminal groups to become a growing menace over the next five years. It was also found that virtually every state and city, regardless of size or geographic location, is vulnerable to the pernicious criminal activities of transnational organized crime groups. Furthermore, it was discovered that most of these criminal networks became active in the United States during the 1990s and are likely to expand their operations in this country in future years. The international dimensions of transnational organized crime were also explored through an examination of how these groups have evolved over the last several decades. These groups have greatly expanded their operations around the world in recent decades due in large part to changes in the geopolitical environment, advances in the transportation and telecommunications industries, the globalization of the world's economies, and the permeability of national boundaries. The threats transnational criminal organizations pose to Americans and their communities, national sovereignty, business and financial institutions, and global security and stability are also examined in this study. Lastly, this study examined some of the major transnational criminal organizations operational in the United States, how they evolved, their criminal operations, and when they first started to penetrate this country.

description: We demonstrate fractal noise in the quantum evolution of wave packets moving either ballistically or diffusively in periodic and quasiperiodic tight-binding lattices, respectively. For the ballistic case with various initial superpositions we obtain a space-time self-affine fractal $Ψ(x,t)$ which verify the predictions by Berry for "a particle in a box", in addition to quantum revivals. For the diffusive case self-similar fractal evolution is also obtained. These universal fractal features of quantum theory might be useful in the field of quantum information, for creating efficient quantum algorithms, and can possibly be detectable in scattering from nanostructures.
