title: Limón Patwa
title: A Perceptual Study to Measure Language Attitudes Toward Speakers of Patwa in Costa Rica
titleType: Subtitle
Creators: name: Bell, Robert
Publisher: name: University of Kentucky Libraries
Year: 2019

description: The primary purpose for this research is to examine and identify the social functions of Limón Patwa, a closely related language to Jamaican Patwa spoken by the Afro-Caribbean community of Costa Rica. There is a unique relationship regarding the language contact between Spanish and LP, where the maintenance of this English based language can certainly be complicated by a Spanish language dominant environment. Studying the historical migration of this Afro-Caribbean population to Costa Rica in the 1800s sheds light on the systemic oppression and the lack of integration into Costa Rican society that Afro-Costa Ricans faced in the midst of their arrival to Puerto Viejo (“the old port”). I conducted 8 sociolinguistic interviews with Limón Patwa speakers with efforts to better understand the usage of Limón Patwa, along with valuable information about being of African descent and living in Costa Rica. In addition to interviews with Patwa speakers, a matched guise audio survey was elicited to that involved listening to speakers of Patwa vs speakers of Spanish along with one audio recording of a Patwa speaker using Spanish. A Likert scale was used for participants to rate these voices as trustworthy, intelligent, and friendly, for example, in order to analyze how Patwa speakers are perceived by the general population. Furthermore, this research gives insight to where negative ideologies surrounding Limón Patwa and its speakers may stem from and how it influences the usage of LP. This study takes into consideration the issues of political power and the aspects of language identity, calling to attention the importance of efforts to maintain this minority language among an underrepresented community.

description: In some previous articles, we defined several partitions of the total kinetic energy T of a system of N classical particles in the d-dimensional Euclidean space into components corresponding to various modes of motion. In the present paper, we propose formulas for the mean values of these components in the normalization T=1 (for any d and N) under the assumption that the masses of all the particles are equal. These formulas are proven at the "physical level" of rigor and numerically confirmed for planar systems (d=2) at N from 3 through 100. The case where the masses of the particles are chosen at random is also considered. The paper complements our article of 2008 [Russian J Phys Chem B, 2(6), 947-963] where similar numerical experiments were carried out for spatial systems (d=3) at N from 3 through 100.

description: While transdisciplinarity offers a way to tackle complex social-ecological challenges, transdisciplinary research is a challenging task in itself. The integration of research methods across academic disciplines, the collaboration between researchers and practitioners, and the need to balance societal and disciplinary academic impacts pose many difficulties even to experienced applied scientists and even more so to early-career researchers. Young scholars face particular problems, given their lack of longer-term experience and their still fragile position within academia. Drawing on existing literature, an early-career researcher workshop, and our own experience as junior research group leaders, we discuss specific challenges and respective solution strategies of transdisciplinary research within the context of sustainability.

description: Abstract
The present research aimed to investigate whether or not a non-salary budget (NSB) may improve the overall productivity of pupils studying at the elementary level. The objectives of the study were to examine the role of a non-salary budget in enhancing the productivity of students, to identify the role of school management committees regarding non-salary budgets, to explore transparency for the Utilization of NSB and to compare the opinions of male and female respondents for the effectiveness of NSB for maximizing the productivity of students. The survey approach was utilized because of the descriptive nature of the investigation. This study's population was drawn from the boys' and girls' public elementary schools in the Bahawalpur district Punjab, Pakistan, which included both rural and urban settings. A multistage selection approach was used to choose a sample of 400 individuals from 20 schools. A questionnaire that the individual produced was given to principals and instructors. A statistical approach was used to examine the data, which involved computing things like frequency and percentage and calculating mean scores, standard deviation, and t-tests. According to the findings, low-income students are eligible for free uniforms, as well as free bags and stationery, as well as free shoes from NSB. NSB is responsible for doing any maintenance for students. The NSB grant was spent honestly with the assistance of SMC to better the students' welfare. Cash books and bills are checked/verified by school council members. Headteachers give priority to the opinions of the members of SMC. MEA visits and checks properly the transparency of doing work, records, and NSB funds. There was a significant difference in the mean score of respondents about the role of NSB; the mean score indicates that NSB was utilized more positively in female schools compared to male schools to enhance the productivity of students at the elementary level. It was suggested that school council committee members and school heads participate in frequent training to enhance the overall performance of schools and the performance of school council committee members and school heads specifically.

description: Die Dissertation ist in zwei Themenbereiche unterteilt. Im ersten Themenbereich dieser Arbeit wurden die vinylogen Kobayashi-Aldolreaktionen ausgehend von (3Z)-Ketenacetal mit chelatisierenden Aldehyden untersucht. Die Studien zeigten dabei, dass ausschließlich die syn-Aldolprodukte erhalten werden konnten. In weiteren Untersuchungen zur syn-selektiven Kobayashi-Aldolreaktion konnte ebenfalls gezeigt werden, dass eine Umsetzung mit einem geschützten Hydroxyaldehyd möglich ist. Im zweiten Themenbereich wurden die Studien zur Totalsynthese von Sulfangolid C behandelt. Sulfangolid C ist ein Naturstoff aus der Klasse der Polyketide, der eine Sulfatester-Funktion besitzt. Sulfangolid C wurde aus dem Myxobakterium Sorangium cellulosum am Helmholtz Zentrum für Infektionsforschung isoliert und zeigt eine geringe antibakterielle Wirkung gegen Gram-positive Bakterien. In einem anti-HIV-Testverfahren konnte ebenfalls eine antivirale Wirksamkeit nachgewiesen werden. Für die Studien zur Totalsynthese von Sulfangolid C wurde die von Kulkenon abgeleitete Struktur angenommen. Als Schlüsselschritt für die Synthese des Westfragments wurde eine substratkontrollierte asymmetrische Aldolreaktion verwendet. Das Grundgerüst des Ostfragments wurde über eine syn-selektive Kobayashi-Aldolreaktion aufgebaut. Ost- und Westfragment wurden durch eine HWE-Reaktion miteinander verknüpft und die makrozyklische Struktur des Sulfangolids in einer nachfolgenden intramolekularen Heck-Reaktion aufgebaut.

description: The presence of chlorofluorocarbons (CFCs) in Earth's atmosphere is a direct result of technology. Ozone-depleting CFCs have been banned by most countries, but some CFCs have persistent in elevated concentrations due to their long stratospheric lifetimes. CFCs are effective greenhouse gases and could serve as a remotely detectable spectral signature of technology. Here we use a three-dimensional climate model and a synthetic spectrum generator to assess the detectability of CFC-11 and CFC-12 as a technosignature on exoplanets. We consider the case of TRAPPIST-1e as well as a habitable Earth-like planet around a 3300 K M-dwarf star, with CFC abundances ranging from one to five times present-day levels. Assuming an optimistic James Webb Space Telescope (JWST) Mid Infrared Instrument (MIRI) low resolution spectrometer (LRS) noise floor level of 10 ppm to multiple co-added observations, we find that spectral features potentially attributable to present or historic Earth-level CFC features could be detected with a SNR $\ge 3-5$ on TRAPPIST-1e, if present, in $\sim 100$ hours of in-transit time. However, applying a very conservative 50 ppm noise floor to co-added observations, even a 5x Earth-level CFC would not be detectable no matter the observation time. Such observations could be carried out simultaneously and at no additional cost with searches for biosignature gases. Non-detection would place upper limits on the CFC concentration. We find that with the launch of JWST, humanity may be approaching the cusp of being able to detect passive atmospheric technosignatures equal in strength to its own around the nearest stars.

Unter Einnahme einer raciolinguistic perspective wird durch episodisch-narrative Interviews aufgezeigt, welche Rolle Sprechverbote in Subjektivierungsprozessen einnehmen. Dabei wird betrachtet, inwiefern Sprechverbote sich als rassistische Praxis ausmachen lassen und adressierte Sprecher*innen als raciolinguistic Others – rassialisiert-sprachliche Andere – markieren. Der Versuch eines Entzugs dieser Markierung durch Interviewte zeigt sich insbesondere durch ein Betonen der Nutzung (nur) der deutschen Sprache, wobei Sprechverbote zeitgleich eine Legitimierung erfahren und als angemessen eingeordnet werden.

description: Redox-based nanoionic resistive memory cells (ReRAMs) are one of the most promising emerging nano-devices for future information technology with applications for memory, logic and neuromorphic computing. Recently, the serendipitous discovery of the link between ReRAMs and memristors and memristive devices has further intensified the research in this field. Here we show on both a theoretical and an experimental level that nanoionic-type memristive elements are inherently controlled by non-equilibrium states resulting in a nanobattery. As a result the memristor theory must be extended to fit the observed non zerocrossing I-V characteristics. The initial electromotive force of the nanobattery depends on the chemistry and the transport properties of the materials system but can also be introduced during ReRAM cell operations. The emf has a strong impact on the dynamic behaviour of nanoscale memories, and thus, its control is one of the key factors for future device development and accurate modelling.

description: Motivated by the intriguing report, in some frustrated quantum antiferromagnets, of magnetization plateaus whose simple collinear structure is {\it not} stabilized by an external magnetic field in the classical limit, we develop a semiclassical method to estimate the zero-point energy of collinear configurations even when they do not correspond to a local minimum of the classical energy. For the spin-1/2 frustrated square-lattice antiferromagnet, this approach leads to the stabilization of a large 1/2 plateau with "up-up-up-down" structure for J_2/J_1>1/2, in agreement with exact diagonalization results, while for the spin-1/2 anisotropic triangular antiferromagnet, it predicts that the 1/3 plateau with "up-up-down" structure is stable far from the isotropic point, in agreement with the properties of Cs_2CuBr_4.

title: Calibration of Hot-Film X-Probes for High Accuracy Angle Alignment in Wind Tunnels
Creators: name: Jackson, Dallin L.
Publisher: name: Utah State University
Year: 2019

description: This thesis investigates the use of hot-film thermal anemometers to align a plate on a wind tunnel at Hill Air Force Base that is used to calibrate Angle of Attack Transmitters on F-16s. A reoccuring problem with this wind tunnel is that no two instruments can verify an angle reading of the the mounting plate for the Angle of Attack Transmitters to the air stream in the wind tunnel. Multiple thermal anemometer calibration methods, such as Jorgensen’s equation and a look-up table are implemented to attempt to achieve consistent measurements between multiple probes. The results show that it is necessary to have conditions match between calibration and measurement when attempting to achieve high accuracy with angle measurements.

description: The Weyl correspondence and the related Wigner formalism lie at the core of traditional quantum mechanics. We discuss here an alternative quantization scheme, whose idea goes back to Born and Jordan, and which has recently been revived in another context, namely time-frequency analysis. We show that in particular the uncertainty principle does not enjoy full symplectic covariance properties in the Born and Jordan scheme, as opposed to what happens in the Weyl quantization.

description: This work deals with braneworld scenarios obtained from N real scalar fields, whose dynamics is generalized to include higher order power in the derivative of the fields. For the scalar fields being driven by nonstandard dynamics, we show how a first-order formalism can be obtained for flat brane in the presence of several fields. We then illustrate our findings investigating distinct potentials with one and two fields, obtaining stable standard and compact solutions in the braneworld theory. In particular, we have found different models describing the very same warp factor.

description: HST transit observations in the near-UV performed in 2009 made WASP-12b one of the most "mysterious" exoplanets; the system presents an early-ingress, which can be explained by the presence of optically thick matter located ahead of the planet at a distance of 4-5 planet radii. This work follows previous attempts to explain this asymmetry with an exospheric outflow or a bow shock, induced by a planetary magnetic field, and provides a numerical solution of the early-ingress, though we did not perform any radiative transfer calculation. We performed pure 3D gas dynamic simulations of the plasma interaction between WASP-12b and its host star, and describe the flow pattern in the system. In particular, we show that the overfilling of the planet's Roche lobe leads to a noticeable outflow from the upper atmosphere in the direction of the L1 and L2 points. Due to the conservation of the angular momentum, the flow to the L1 point is deflected in the direction of the planet's orbital motion, while the flow towards L2 is deflected in the opposite direction, resulting in a non-axisymmetric envelope, surrounding the planet. The supersonic motion of the planet inside the stellar wind leads to the formation of a bow shock with a complex shape. The existence of the bow shock slows down the outflow through the L1 and L2 points, allowing us to consider a long-living flow structure which is in the steady-state.

description: The solar cycle and its associated magnetic activity are the main drivers behind changes in the interplanetary environment and the Earth's upper atmosphere (commonly referred to as space weather). These changes have a direct impact on the lifetime of space-based assets and can create hazards to astronauts in space. In recent years there has been an effort to develop accurate solar cycle predictions (with aims at predicting the long-term evolution of space weather), leading to nearly a hundred widely spread predictions for the amplitude of solar cycle 24. A major contributor to the disagreement is the lack of direct long-term databases covering different components of the solar magnetic field (toroidal vs.\ poloidal). Here we use sunspot area and polar faculae measurements spanning a full century (as our toroidal and poloidal field proxies), to study solar cycle propagation, memory, and prediction. Our results substantiate predictions based on the polar magnetic fields, whereas we find sunspot area to be uncorrelated to cycle amplitude unless multiplied by area-weighted average tilt. This suggests that the joint assimilation of tilt and sunspot area is a better choice (with aims to cycle prediction) than sunspot area alone, and adds to the evidence in favor of active region emergence and decay as the main mechanism of poloidal field generation (i.e. the Babcock-Leighton mechanism). Finally, by looking at the correlation between our poloidal and toroidal proxies across multiple cycles, we find solar cycle memory to be limited to only one cycle.

description: The microscopic composition and properties of matter at super-saturation densities have been the subject of intense investigation for decades. The scarcity of experimental and observational data has lead to the necessary reliance on theoretical models. However, there remains great uncertainty in these models, which, of necessity, have to go beyond the over-simple assumption that high density matter consists only of nucleons and leptons. Heavy strange baryons, mesons and quark matter in different forms and phases have to be included to fulfil basic requirements of fundamental laws of physics. In this review the latest developments in construction of the Equation of State (EoS) of high-density matter at zero and finite temperature assuming different composition of the matter are surveyed. Critical comparison of model EoS with available observational data on neutron stars, including gravitational masses, radii and cooling patterns is presented. The effect of changing rotational frequency on the composition of neutron stars during their lifetime is demonstrated. Compatibility of EoS of high-density, low temperature compact objects and low density, high temperature matter created in heavy-ion collisions is discussed.

In particular we obtain forcing equivalents of the posets of copies of countable equivalence relations, disconnected ultrahomogeneous graphs and some partial orderings.

description: Ecosystems can undergo sudden shifts to undesirable states, but recent studies with simple single species ecosystems have demonstrated that advance warning can be provided by the slowing down of population dynamics near a tipping point. However, it is not clear how this effect of critical slowing down will manifest in ecosystems with strong interactions between their components. Here we probe the dynamics of an experimental producer parasite ecosystem as it approaches a catastrophic collapse. Surprisingly, the producer population grows in size as the environment deteriorates, highlighting that population size can be a misleading measure of ecosystem stability. By analyzing the oscillatory producer parasite dynamics for over ~100 generations in multiple environmental conditions, we found that the collective ecosystem dynamics slows down as the tipping point is approached. Analysis of the coupled dynamics of interacting populations may therefore be necessary to provide advance warning of collapse in complex communities.

The Matsubara and real frequency itinerant electron Green's functions, the evolution of the system with doping, and the range of phase separation are found in two approximations. At large values of the on-site Coulomb repulsion both approximations give similar results. The phase separation can be also favorable for a more general model, where heavy electrons have a finite bandwidth. This indicates that the phase separation phenomenon is an inherent feature of the systems described by the Hubbard-like models with wide and narrow bands.

description: The characterization of multiple stellar systems is an important ingredient for testing current star formation models. Stars are more often found in multiple systems, the more massive they are. A complete knowledge of the multiplicity of high-mass stars over the full range of orbit separations is thus essential to understand their still debated formation process. Observations of the Orion Nebula Cluster can help to answer the question about the origin and evolution of multiple stars. Earlier studies provide a good knowledge about the multiplicity of the stars at very small (spectroscopic) and large separations (AO, speckle) and thus make the ONC a good target for such a project. We used the NIR interferometric instrument AMBER at VLTI to observe a sample of bright stars in the ONC. We complement our data set by archival NACO observations of θ1 Ori A to obtain more information about the orbit of the close visual companion. Our observations resolve the known multiple systems θ1 Ori C and θ1 Ori A and provide new orbit points, which confirm the predicted orbit and the determined stellar parameters for θ1 Ori C. Combining AMBER and NACO data for θ1 Ori A we were able to follow the motion of the companion from 2003 to 2011. We furthermore find hints for a companion around θ1 Ori D and a previously unknown companion to NU Ori. With a probability of ~90% we can exclude further companions with masses of > 3 Msun around our sample stars for separations between ~2 mas and ~110 mas. We conclude that the companion around θ1 Ori A is most likely physically related to the primary star. The newly discovered possible companions further increase the multiplicity in the ONC. For our sample of two O and three B-type stars we find on average 2.5 known companions per primary, which is around five times more than for low-mass stars.

description: This thesis contains three essays on spurious long memory with an introduction to the literature in the first Chapter. Chapter 2 presents a multivariate score-type test against spurious long memory. We prove the consistency of the test against the alternatives of random level shifts and smooth trends. The test statistic is based on the weighted sum of the partial derivatives of the multivariate local Whittle likelihood function. To apply the test to fractionally cointegrated series, the test statistic is calculated for the linearly transformed system after estimating the cointegrating matrix. We derive the limiting distribution and show consistency of this procedure. The test is applied to log-absolute returns and log-realized volatilities of the S&P 500, DAX, FTSE, and NIKKEI. Chapter 3 analyzes inflation rates with newly available econometric methods which allow for a consistent estimation of the persistence parameter under low frequency contaminations and con- sistent break point estimation under long memory without a priori assumptions on the presence of breaks. The persistence of inflation rates is of major importance to central banks due to the fact that it determines the costs of monetary policy according to the Phillips curve. In contrast to previous studies, smooth trends are allowed in addition to breaks as a source of spurious long memory. We support the finding of reduced memory parameters in monthly inflation rates of the G7 countries as well as spurious long memory, except for the US. Nevertheless, only a few breaks can be located. Instead, all countries exhibit significant trends at the 5% level with the exception of the US. Finally, Chapter 4 provides an overview and compares the performance of nine semiparametric estimation methods. Among them are two standard methods, four modified approaches to account for low frequency contaminations and three procedures developed for perturbed fractional processes. Several modified estimation methods of the memory parameter have been introduced in the past years. They aim to decrease the upward bias of the memory parameter in cases of low frequency contaminations or an additive noise component, especially in situations with a short-memory process being contaminated. We conduct an extensive Monte Carlo study for a variety of parameter constellations and several DGPs. Furthermore, an empirical application of the log-absolute return series of the S&P 500 shows that the estimation results combined with a long-memory test indicate a spurious long-memory process.

description: Im Fokus des Beitrags stehen zwei qualitative Forschungsprojekte, die Mehrsprachigkeit von Kindern in institutionellen bzw. familiären Kontexten untersuchen. Anhand von empirischen Beispielen wird der Frage nachgegangen, inwiefern sprachbezogene Wissensbestände und Zuschreibungen in Form von Positionierungen als Sprecher:innen bedeutsam werden. Ausgehend von Bezugspunkten einer (selbst-)reflexiven Forschungspraxis werden die Potentiale von Partizipation für die Verknüpfung von Perspektiven sowie die Aushandlung von Positionierungen und Wissensbeständen im Kontext der Mehrsprachigkeitsforschung mit Kindern diskutiert.

description: We introduce Sashimi plots, a quantitative multi-sample visualization of mRNA sequencing reads aligned to gene annotations. Sashimi plots are made using alignments (stored in the SAM/BAM format) and gene model annotations (in GFF format), which can be custom-made by the user or obtained from databases such as Ensembl or UCSC. We describe two implementations of Sashimi plots: (1) a stand-alone command line implementation aimed at making customizable publication quality figures, and (2) an implementation built into the Integrated Genome Viewer (IGV) browser, which enables rapid and dynamic creation of Sashimi plots for any genomic region of interest, suitable for exploratory analysis of alternatively spliced regions of the transcriptome. Isoform expression estimates outputted by the MISO program can be optionally plotted along with Sashimi plots. Sashimi plots can be used to quickly screen differentially spliced exons along genomic regions of interest and can be used in publication quality figures. The Sashimi plot software and documentation is available from: http://genes.mit.edu/burgelab/miso/docs/sashimi.html

description: This dissertation comprises four articles concerning tax evasion and tax avoidance. The first study investigates if a one set of books transfer pricing strategy can be part of a multinational’s equilibrium strategy even though two sets of books provide an additional degree of freedom when transfer pricing is used for tax reporting and internal decision making. Using a game theoretic model the article shows that the penalty difference between the transfer pricing regimes in case of a detected non-compliant transfer price critically affects whether the multinational uses one set or two sets of books. Furthermore, the study shows that an increasing tax rate differential induces less tax-aggressiveness because high profit shifting incentives are anticipated by a strategic tax auditor. The second article analyzes transfer pricing of an intangible while endogenizing its location choice. Multinationals are often suspected of using transfer pricing of intangibles to shift profits from high-tax to low-tax jurisdictions. However, if spillovers from the use of the intangible are prevalent and the multinational faces a trade-off between spillover internalization and tax minimization a ’home bias’ might occur. In particular, for a high spillover and restrictions on tax avoidance, the intangible is optimally located in the headquarters which is in the high-tax country even though tax savings could be realized by locating the intangible in an offshore division. Additionally, the study shows that curtailing profit shifting possibilities can harm investment incentives. The third article investigates the interdependence between a firm’s tax reporting and investment behavior if the financial statement provides a noisy signal regarding the correct tax treatment of the project to a strategically acting tax authority. The study shows that the expected tax revenue for the tax authority can either increase or decrease with increasing book-tax conformity. Increasing book-tax conformity is detrimental for the investment incentives but leads to less understated non-conforming tax reports. The fourth article examines how taxes and the transfer pricing regulation affect the capacity planning of a multinational company. In a situation where tight regulation curbs the reporting discretion, multinationals can shift profits to low-tax jurisdictions by adapting real decisions instead of manipulating the transfer price. The article shows that taxes and transfer pricing regulation increase the probability of excessive capacity. Therefore, taxes and corresponding regulation are identified as potential antecedents for organizational slack.

description: The review provides information on some aspects of comorbid pathology, as well as features of the rehabilitation process in cerebral palsy. There is currently no uniform system of views in understanding of etiological criteria, patho-genesis, diagnostic aspects of the disease, the assessment of the severity, as well as factors that influence the course of illness. Processes of endothelial dysfunction and oxidative stress contributing to dystrophic changes of neurons, disor-ders of the cardiovascular system are closely interrelated. There are certain difficulties in the formation of a rehabilita-tion program in children with cerebral palsy. Part of the problem lies in the low adaptability of the child’s body to in-creasing physical exertion, caused both by the manifestation of the underlying disease and by the presence of comorbid pathology, which exacerbates the severity of the child’s condition.
Key words: infantile cerebral palsy, excitotoxicity, comorbid pathology, rehabilitation, cardiovascular system, respiratory system.
