description: This dissertation examines the impact of everyday relations and activities of public school teachers in Puerto Rico on Puerto Rican state formation. I bring both historic attention to public school teachers and Puerto Rican state formation across the twentieth century and particular ethnographic attention to the neoliberal reconfigurations of schooling and state in Puerto Rico in the 1990s. I look historically at state use of race, gender and class ideologies to construct claims and expectations toward teachers under both official U.S. colonialism and by the current Commonwealth government under pressures from the U.S. Department of Education. I trace the diversity of teachers' historically constructed social relations and examine how different teachers have used these, collectively and individually, to both confound and confirm state-based mandates for school reform. My analysis is based on seventeen months of fieldwork in Puerto Rican public schools in 1999 and 2000, as well as primary research in the Puerto Rican state archives and the Puerto Rican Department of Education. My fieldwork included eight months of participant observation in schools, teacher surveys in four schools, two focus group interviews with teachers and one with mothers, and fifty-seven individual interviews with teachers, administrators, state officials, and parents and community members. Through cycles of "crisis" and reform that have historically marked shifts in Puerto Rican state formation and corresponding public education policies, public school teachers in Puerto Rico have been charged with the responsibility of forming the particular kind of person needed to facilitate each of these dominant modes of Puerto Rican state relations. Viewed from the lives and experiences of public school teachers in Puerto Rico, these historical processes of Puerto Rican state formation point to ongoing tensions in teachers' daily lives between autonomy and control and coercion and consent. Such tensions have also marked the historical relations between the U.S. and Puerto Rican states. As teachers oppose, appropriate, and accommodate state directives concerning policies, structures, and curricula, their actions and inactions leave their mark on Puerto Rican state formation and U.S.-Puerto Rican state relations.

description: We propose a novel method for gradient-based optimization of black-box simulators using differentiable local surrogate models. In fields such as physics and engineering, many processes are modeled with non-differentiable simulators with intractable likelihoods. Optimization of these forward models is particularly challenging, especially when the simulator is stochastic. To address such cases, we introduce the use of deep generative models to iteratively approximate the simulator in local neighborhoods of the parameter space. We demonstrate that these local surrogates can be used to approximate the gradient of the simulator, and thus enable gradient-based optimization of simulator parameters. In cases where the dependence of the simulator on the parameter space is constrained to a low dimensional submanifold, we observe that our method attains minima faster than baseline methods, including Bayesian optimization, numerical optimization, and approaches using score function gradient estimators.

description: The more precise extraction for the CKM matrix element |V_{cb}| in the heavy quark effective field theory (HQEFT) of QCD is studied from both exclusive and inclusive semileptonic B decays. The values of relevant nonperturbative parameters up to order 1/m^2_Q are estimated consistently in HQEFT of QCD. Using the most recent experimental data for B decay rates, |V_{cb}| is updated to be |V_{cb}| = 0.0395 \pm 0.0011_{exp} \pm 0.0019_{th} from B\to D^{\ast} l νdecay and |V_{cb}| = 0.0434 \pm 0.0041_{exp} \pm 0.0020_{th} from B\to D l νdecay as well as |V_{cb}| = 0.0394 \pm 0.0010_{exp} \pm 0.0014_{th} from inclusive B\to X_c l νdecay.

description: Existing explanations of party change do not explain why parties might take long time to adapt, or why they make choices that may not be "rational" at all. Part of the problem lies in treating the party as a unitary actor pursuing one primary goal, be it vote getting, office-getting or policy-getting. Such objections have been addressed by work that views parties as a collection of different groups. The model in this project explains party change as the result of rational choices made by competing internal groups seeking different goals within the same party. The main argument is that internal party groups pursue their own goals, their own rationality within the party, according to their hierarchy of preferences. Following Panebianco, the project maintains that change in the party as a whole follows competition between internal groups. A new coalition of internal groups may form in the party, and environmental conditions will shape whether that coalition becomes dominant. Adopting Kitschelt's typology of groups in social democratic parties, the model focuses centrists, ideologues and workers, each acting rationally to improve its preferred combination of electoral, ideological and economic payoffs. Each group has a different hierarchy of preferences, and each group dominates specific resources that help improve payoffs for the others. External electoral, economic and institutional conditions shape the priorities of each party grouping, and also the relative value of the resources controlled by each group. The model therefore helps predict the choice of coalition partners, as each group seeks to improve its combination of payoffs. The internal party context (party centralization and leadership autonomy) will then shape which coalitions become dominant, leading to party change. The model is tested by examining seventeen major conflicts (centered on party identity, policy and organization) in three large social democratic parties (PSOE, SPD and Labour), over a period from 1959 to 1989. The model is found to be quite useful in explaining the outcomes of party conflict, and points to further research on party structure, membership and goals.

description: Inference based on cluster-robust standard errors in linear regression models, using either the Student’s t distribution or the wild cluster bootstrap, is known to fail when the number of treated clusters is very small. We propose a family of new procedures called the subcluster wild bootstrap, which includes the ordinary wild bootstrap as a limiting case. In the case of pure treatment models, where all observations within clusters are either treated or not, the latter procedure can work remarkably well. The key requirement is that all cluster sizes, regardless of treatment, should be similar. Unfortunately, the analogue of this requirement is not likely to hold for difference-in-differences regressions. Our theoretical results are supported by extensive simulations and an empirical example.

description: A sample of about 3,800 Low Surface Brightness (LSB) galaxies was selected using the all-sky near-infrared (J, H and K_s-band) 2MASS survey. The selected objects have a mean central surface brightness within a 5 arcsec radius around their centre fainter than 18 mag/sq.arcsec in the K_s band, making them the lowest surface brightness galaxies detected by 2MASS. A description is given of the relevant properties of the 2MASS survey and the LSB galaxy selection procedure, as well as of basic photometric properties of the selected objects. The latter properties are compared to those of other samples of galaxies, of both LSBs and `classical' high surface brightness (HSB) objects, which were selected in the optical. The 2MASS LSBs have a (B_T_c)-(K_T) colour which is on average 0.9 mag bluer than that of HSBs from the NGC. The 2MASS sample does not appear to contain a significant population of red objects.

description: The evolution of slow--roll inflation in a five--dimensional brane world model with two boundary branes and bulk scalar field is studied. Assuming that the inflationary scale is below the brane tension, we can employ the moduli space approximation to study the dynamics of the system. Detuning the brane tension results in a potential for the moduli fields which we show will not support a period of slow--roll inflation. We then study an inflaton field, confined to the positive tension brane, to which the moduli fields are non--minimally coupled. We discuss in detail the two cases of $V(χ) = {1/2} m^2 χ^2$ and $V(χ) = λχ^4$ and demonstrate that increasing the coupling results in spectra which are further away from scale--invariance and in an increase in the tensor mode production, while entropy perturbations are subdominant. Finally, we point out that the five--dimensional spacetime is unstable during inflation because the negative tension brane collapses.

The integrity of the corpus callosum in individuals following mild head injury

Publisher: name: American University

description: Moderate and severe traumatic brain injury can produce diffuse axonal injury (DAI), which often includes damage to the corpus callosum. It is not clear, however, whether callosal dysfunction can also occur in cases of mild traumatic brain injury (MTBI). Right-handed adults (18--79 years old), including 21 survivors of a MTBI (18 women) (occurring within five years of the start of this study) and 21 uninjured controls (17 women) volunteered. Baseline measures consisted of the Lethbridge Neuropsychological Battery and several other cognitive tests, including the WAIS-III. I used several tasks to measure the integrity of the interhemispheric transfer of auditory, visual, and somatosensory information via the corpus callosum (Dichotic Listening, Fused Words, a series of Tachistoscope (T-Scope Tasks), and Haptic). Both groups showed a right ear advantage on the Dichotic Listening and Fused Words Tasks. Performances on all callosal tests were similar for both groups with the following exceptions: T-Scope Matching Task latency, T-Scope Verbal Color Discrimination Task accuracy, and Haptic Task latency. The MTBI group was significantly slower than the Control group when using their right hand to respond to stimuli presented to the left visual field on the T-Scope Matching Task. When using their left hands to respond, however, both groups were less accurate during the non-transfer than the transfer conditions. Further, the Control group was significantly slower at responding on the non-transfer than the transfer conditions of this task. The MTBI group was significantly less accurate in verbally stating if two disks were the same or different in color on the Verbal Color Discrimination Task. Finally, the MTBI group was significantly slower than Controls in identifying shapes on the Haptic Task. These findings suggest corpus callosum dysfunction might occur even after a single MTBI, however, the most persistent symptom may be an increase in the crossed-uncrossed difference during tactile information transfer.

description: Embaphion glabrum Blaisdell, 1909
(Fig. 2A)
 Diagnosis. Broadly elongate- oval, lateral margins of pronotum and lateral elytral carina acute and foliaceous (laminar and curled upward). Elytra glabrous, smooth without asperate punctures. Lateral elytral carina ends just before posterior elytral apex, although sometimes faintly traceable, never distinct as in E. contusum. Elytral apex acute, though males not tending towards caudate, as in E. contusum.
 Distribution. Mohave, Coconino, Navajo, and Apache Counties, Arizona. New Mexico, Utah.
 Remarks. This species strongly resembles E. contusum and can be separated from it by the elytral sculpturing and elytral margins. Embaphion glabrum can be found reliably in aeolian sand formations of the Arizona Strip, north of the Grand Canyon.

description: The inverse problem for a disordered system involves determining the interparticle interaction parameters consistent with a given set of experimental data. Recently, Rutledge has shown (Phys. Rev. E63, 021111 (2001)) that such problems can be generally expressed in terms of a grand canonical ensemble of polydisperse particles. Within this framework, one identifies a polydisperse attribute (`pseudo-species') $σ$ corresponding to some appropriate generalized coordinate of the system to hand. Associated with this attribute is a composition distribution $\barρ(σ)$ measuring the number of particles of each species. Its form is controlled by a conjugate chemical potential distribution $μ(σ)$ which plays the role of the requisite interparticle interaction potential. Simulation approaches to the inverse problem involve determining the form of $μ(σ)$ for which $\barρ(σ)$ matches the available experimental data. The difficulty in doing so is that $μ(σ)$ is (in general) an unknown {\em functional} of $\barρ(σ)$ and must therefore be found by iteration. At high particle densities and for high degrees of polydispersity, strong cross coupling between $μ(σ)$ and $\barρ(σ)$ renders this process computationally problematic and laborious. Here we describe an efficient and robust {\em non-equilibrium} simulation scheme for finding the equilibrium form of $μ[\barρ(σ)]$. The utility of the method is demonstrated by calculating the chemical potential distribution conjugate to a specific log-normal distribution of particle sizes in a polydisperse fluid.

The transformation of the United States manufacturing industries in the late 20th century and its impact on the manufacturing worker
Creators: name: Dunn, David Patrick
Publisher: name: American University
Year: 2023

description: In reaction to various international and domestic social-economic events, the productive operations of U.S. manufacturers have experienced a transformation during the time period of 1945 to 1999. During this transformation, U.S. manufacturers have utilized two primary strategies to counter the growing competition from foreign manufacturers. Consequentially, the strategies implemented by U.S. manufactures have impacted the amount of quality jobs held by manufacturing workers. A historical research design utilizing both historiography and time series analyses is used to explain the how various social-economic events have influenced the transformation of U.S. manufacturers and how the two strategies used by U.S. manufacturers during their transformation has led to a decline in the amount of quality jobs held by manufacturing workers. In the historiography, existing texts with supporting data are utilized to delineate the occurrence of these social-economic events over time period of 1945 to 1999 and then, show how these events have impacted the competitive status of U.S. manufacturers. The timeline of this analysis has been dimensioned into two types of social-economic events, international and U.S. domestic. Findings from the historiography characterize the U.S. manufacturing industries' transformation as the following: (a) the transformation is from a primarily U.S. owned and operated production process to a multinational process; (b) while U.S. manufacturers were deindustrializing, many foreign investors were also industrializing the U.S. economy; and (c) U.S. manufacturers in late 1990s were more competitive than their counterparts in the early 1970s. The time series analysis uses secondary data to assess how the two competitive strategies utilized by U.S. manufacturers, deindustrialization and operational restructuring, have impacted the amount of quality jobs held by U.S. manufacturing workers. The study period for the time series analysis is from year 1970 to year 1999. Findings from this analysis illustrate how these strategies have produced both favorable and unfavorable consequences for U.S. manufacturing workers. Favorably, U.S. manufacturing workers during the 1990s were predominantly more educated and productive than their counterparts in the 1970s. The unfavorable findings suggest that not only were there less jobs for manufacturing workers in the late 1990s, compared to the 1970s, but also they received lower real wages and benefits.

description: Inference using large datasets is not nearly as straightforward as conventional econo- metric theory suggests when the disturbances are clustered, even with very small intra- cluster correlations. The information contained in such a dataset grows much more slowly with the sample size than it would if the observations were independent. More- over, inferences become increasingly unreliable as the dataset gets larger. These asser- tions are based on an extensive series of estimations undertaken using a large dataset taken from the U.S. Current Population Survey.

description: This paper illustrates the problems that arise with traditional tests for the hot hand and proposes instead using a consistent dynamic panel data estimator, which corrects for these problems and is easy to implement. Applying this estimator to a large dataset of amateur, youth golfers, we find no evidence of either hot or cold hand effects. When we restrict attention to the most-amateur of the golfers in our data, we do see weak evidence of a small hot hand. Thus casual athletes may experience small hot hands, but the effect does not persist among more serious athletes. This may give insight into why the belief in the hot hand in professional sports exists, even when the evidence suggests otherwise.

Bradymerus triplehorni superficially resembles Bradymerus kinabalicus Schawaller (Schawaller 2006: fig. 45) in the general body characters, especially in the surface character of the pronotum and elytra. In B. kinabalicus, the last three antennomeres form a club, the male protibiae are equipped with a tooth, the pronotum is broader, the elytra are less convex transversely, somewhat flattened dorsally, the tibiae are smooth, and the shape of aedeagus is distinctly different (compare Fig. 2 with Schawaller 2006: fig. 110).
 Type Material. Holotype male (NME) and paratype female (CRG): West Malaysia, Kelantan, 70 km NW of Gua Musang, Mt. Chamah, 1900 m, Kampong Perias, 17.IV. – 9.V.2014, P. Čechovský lgt.
 Etymology. The author takes pleasure in naming this species in honor of Charles A. Triplehorn for his valuable contributions to the knowledge of the family Tenebrionidae.

description: This paper investigates the effects of unconventional monetary policy in Canada. We use recently proposed methods to construct a shadow interest rate that captures monetary policy at the zero lower bound (ZLB) and estimate a small open economy Bayesian structural vector autoregressive (B-SVAR) model. Controlling for the US macroeconomic and monetary policy variables, we find that Canadian unconventional monetary policy increased Canadian output by 0.23% per month on average between April 2009 and June 2010. Our empirical framework also allows us to quantify the effects of US unconventional monetary policy, which raised US and Canadian output by 1.21% and 1.94% per month, respectively, on average over the 2008-2015 period.

description: An optical cluster finder inevitably suffers from projection effects, where it misidentifies a superposition of galaxies in multiple halos along the line-of-sight as a single cluster. Using mock cluster catalogs built from cosmological N-body simulations, we quantify the impact of these projection effects with a particular focus on the observables of interest for cluster cosmology, namely the cluster lensing and the cluster clustering signals. We find that "observed" clusters, i.e. clusters identified by our cluster finder algorithm, exhibit lensing and clustering signals that deviate from expectations based on a statistically isotropic halo model -- while both signals agree with halo model expectations on small scales, they show unexpected boosts on large scales, by up to a factor of 1.2 or 1.4 respectively. We identify the origin of these boosts as the inherent selection bias of optical cluster finders for clusters embedded within filaments aligned with the line-of-sight, and show that a minority ($\sim 30\%$) of such clusters within the entire sample is responsible for this observed boost. We discuss the implications of our results on previous studies of optical cluster, as well as prospects for identifying and mitigating projection effects in future cluster cosmology analyses.

description: Although more and more language pairs are covered by machine translation services, there are still many pairs that lack translation resources. Cross-language information retrieval (CLIR) is an application which needs translation functionality of a relatively low level of sophistication since current models for information retrieval (IR) are still based on a bag-of-words. The Web provides a vast resource for the automatic construction of parallel corpora which can be used to train statistical translation models automatically. The resulting translation models can be embedded in several ways in a retrieval model. In this paper, we will investigate the problem of automatically mining parallel texts from the Web and different ways of integrating the translation models within the retrieval process. Our experiments on standard test collections for CLIR show that the Web-based translation models can surpass commercial MT systems in CLIR tasks. These results open the perspective of constructing a fully automatic query translation device for CLIR at a very low cost.

description: In general, quantum systems most likely undergo open system dynamics due to their smallness and sensitivity. Energy storage devices, so-called quantum batteries, are not excluded from this phenomenon. Here, we study fundamental bounds on the power of open quantum batteries from the geometric point of view. By defining an \emph{activity operator}, a tight upper bound on the charging power is derived for the open quantum batteries in terms of the fluctuations of the activity operator and the quantum Fisher information. The variance of the activity operator may be interpreted as a generalized thermodynamic force, while the quantum Fisher information describes the speed of evolution in the state space of the battery. The thermodynamic interpretation of the upper bound is discussed in detail. As an example, a model for the battery, taking into account the environmental effects, is proposed, and the effect of dissipation and decoherence during the charging process on both the stored work and the charging power is investigated. Our results show that the upper bound is saturated in some time intervals. Also, the maximum value of both the stored work and the corresponding power is achieved in the non-Markovian underdamped regime.

description: Chagas disease is caused by Trypanosoma cruzi and affects the poorest population in the Americas. Fourteen plant extracts and seventeen sesquiterpene lactones from the tribe Vernonieae (Asteraceae), were evaluated for the first time against T. cruzi. Cytotoxicity employing HeLa cells was also assessed. The best results were obtained with leaves and flowers rinse extracts from Vernonanthura nebularum (E-1 and E-3) and Elephantopus mollis (E-11 and E-13), with IC50 values <2 µg/mL, being E-1 the most active (IC50 = 0.8 µg/mL). Additionally, these extracts displayed a good selectivity (SI > 10). The most active sesquiterpene lactones, isolated from the extracts, were 2 (2-methoxy-2,5-epoxy-8-methacryloxygermacra-3Z,11(13)-dien-6,12-olide) and 6 (2-ethoxy-2,5-epoxy-8-angeloxygermacra-3Z,11(13)-dien-6,12-olide) from V. nebularum and 12 (8α-methacryloxyhirsutinolide 13-O-acetate) from V. pinguis, with IC50 of 1.5, 2.1 and 2.0 µM, respectively. These compounds showed SI values >14, better than those of the reference drug nifurtimox. Plants living in South American ecosystems could become a potential source of trypanocidal agents.

description: An increase in energy-cost can induce energy effciency improvement - a reduction in energy-output ratio. There are well-established theoretical conjectures of how this can take place. As the relative energy-cost increases, it induces firms to reallocate and selectively utilize the most energy-effcient vintages. In the long-run firms could also achieve energy effciency through investments in energy-effcient capital. This study uses the Canadian KLEMS panel data set to investigate these relationships. We employ panel vector auto regressions as well as co-integration and error correction techniques to test whether the conjectures hold in the data. Our findings support the theoretical conjectures. The channels we empirically identify suggest that the effect of increased energy-cost can be an increase in energy effciency: by decreasing energy-capital ratio and increasing output-capital ratio. The latter effect is observed only in the long-run through induced investments in new capital.

description: In reaction to various international and domestic social-economic events, the productive operations of U.S. manufacturers have experienced a transformation during the time period of 1945 to 1999. During this transformation, U.S. manufacturers have utilized two primary strategies to counter the growing competition from foreign manufacturers. Consequentially, the strategies implemented by U.S. manufactures have impacted the amount of quality jobs held by manufacturing workers. A historical research design utilizing both historiography and time series analyses is used to explain the how various social-economic events have influenced the transformation of U.S. manufacturers and how the two strategies used by U.S. manufacturers during their transformation has led to a decline in the amount of quality jobs held by manufacturing workers. In the historiography, existing texts with supporting data are utilized to delineate the occurrence of these social-economic events over time period of 1945 to 1999 and then, show how these events have impacted the competitive status of U.S. manufacturers. The timeline of this analysis has been dimensioned into two types of social-economic events, international and U.S. domestic. Findings from the historiography characterize the U.S. manufacturing industries' transformation as the following: (a) the transformation is from a primarily U.S. owned and operated production process to a multinational process; (b) while U.S. manufacturers were deindustrializing, many foreign investors were also industrializing the U.S. economy; and (c) U.S. manufacturers in late 1990s were more competitive than their counterparts in the early 1970s. The time series analysis uses secondary data to assess how the two competitive strategies utilized by U.S. manufacturers, deindustrialization and operational restructuring, have impacted the amount of quality jobs held by U.S. manufacturing workers. The study period for the time series analysis is from year 1970 to year 1999. Findings from this analysis illustrate how these strategies have produced both favorable and unfavorable consequences for U.S. manufacturing workers. Favorably, U.S. manufacturing workers during the 1990s were predominantly more educated and productive than their counterparts in the 1970s. The unfavorable findings suggest that not only were there less jobs for manufacturing workers in the late 1990s, compared to the 1970s, but also they received lower real wages and benefits.

description: Recently, superconductivity in PuCoGa5 was discovered. It has the same crystal structure as CeMIn5(M=Ir, Co, Rh). The electron correlation in PuCoGa5 is estimated to be weak compared with CeMIn5, and the filling number of electrons is considered to be far from 0.5/spin in the band which plays an important role in realizing the superconductivity. Nevertheless, the superconducting transition temperature Tc in PuCoGa5 is almost by an order of magnitude higher than that in CeMIn5. In order to explain the superconductivity with high Tc, we adopt the periodic Anderson model and calculate Tc by solving the Dyson-Gor'kov equation derived by the third order perturbation theory with respect to U. By this calculation, we indicate that the superconducting state of PuCoGa5 is a d-wave pairing state, and show that the good location of two Fermi surfaces results in the high Tc in PuCoGa5.
