College Choice Priorities between Foreign-born and US-born Black Students
Creators: name: Okorie, Sarah
Publisher: name: American University
Year: 2023

description: This study investigates the differences in college choice priorities between foreign-born and US-born Black students in order to explain the large presence of Black immigrants in the Black population at top universities relative to their proportion in the nation's Black college-age population. Ogbu's cultural-ecological theory and Bourdieu's cultural capital concept guided this research in that foreign-born students were expected to seek aspects of colleges that would enhance their cultural capital, such as college rankings, while US-born students were expected to choose colleges based on more practical aspects of colleges, such as low tuition, because of these groups' different historical contexts in America. However, there was no supporting evidence for our main hypotheses. Instead, mother's education, number of college applications, and income were found related to college choice. Such findings suggest that for college choice immigrant status is not important. Further research may switch focus to college admissions officers' decisions.

description: Im Kreis Emsland soll das südlich des Küstenkanals gelegene ehemalige Hochmoor "Leegmoor" (Topographische Karte 1 : 25 000, Blatt 2911 Burlage und 3011 Esterwegen) nach Abschluß des Schwarztorfabbaues wieder vernäßt werden mit dem Ziel einer Regeneration der Moorvegetation. Damit wird erstmals in der Bundesrepublik ein größeres und zusammenhängend nahezu restlos abgebautes Hochmoor wieder vernäßt. Gegenüber den bekannte Verfahren zur Wiedervernässung von Hochmoorflächen, bei denen nach dem Weißtorfabbau der Schwarztorf erhalten geblieben ist, sind hier einige Änderungen vorgesehen, die insbesondere die Verminderung der Versickerung von Wasser in den Untergrund zum Ziel haben. Die Vegetationsentwicklung soll durch gezielte Maßnahmen eingeleitet und gelenkt werden. Die hydrologischen, botanischen und zoologischen Entwicklungen auf dem Versuchsgelände werden durch ein intensives wissenschaftliches Begleitprogramm verfolgt und dokumentiert.
description: The former raised bog "Leegmoor" in the Emsland south of the Küstenkanal (Topographical map 1 : 25 000, sheet 2911 Burlage and 3011 Esterwegen) shall be rewetted, when the black-peat excavation will be finished. The bog vegetation shall regenerate as far as possible. It is the first rewetting project of an extended bog nearly completely cleared of peat in the Federal Republic of Germany. There are well known methods to rewet raised bogs in which the black-peat layers are left after the white peat has been removed. These methods must be modified according to the conditions in the cutaway field in order to lower the rate of water seepage into the mineral subsoil. The development of the vegetation will be stimulated by planned steps. The hydrological, the botanical and the zoological development will be observed and documented by an extended scientifical program.

description: Large discrepancy of the p-wave phase shift data $δ_{1}(ν)$ of the $π$-$π$ scattering from those of the dispersion calculation is pointed out. In order to determine which is correct, the pion form factor $F_π(ν)$, which is the second source of information of the phase shift $δ_{1}(ν)$, is used. It is found that the phase shift obtained from the dispersion is not compatible with the data of the pion form factor. What is wrong with the dispersion calculation, is considered.

description: We investigate the two-component quantum walk in one-dimensional lattice. We show that the inter-component interaction strength together with the hopping imbalance between the components exhibit distinct features in the quantum walk for different initial states. When the walkers are initially on the same site, both the slow and fast particles perform independent particle quantum walks when the interaction between them is weak. However, stronger inter-particle interactions result in quantum walks by the repulsively bound pair formed between the two particles. For different initial states when the walkers are on different sites initially, the quantum walk performed by the slow particle is almost independent of that of the fast particle, which exhibits reflected and transmitted components across the particle with large hopping strength for weak interactions. Beyond a critical value of the interaction strength, the wave function of the fast particle ceases to penetrate through the slow particle signalling a spatial phase separation. However, when the two particles are initially at the two opposite edges of the lattice, then the interaction facilitates the complete reflection of both of them from each other. We analyze the above mentioned features by examining various physical quantities such as the on-site density evolution, two-particle correlation functions and transmission coefficients.

description: In this article, we illustrate how to calculate the hadronic coupling constants of the pentaquark states with the QCD sum rules based on rigorous quark-hadron quality, then study the hadronic coupling constants of the lowest diquark-diquark-antiquark type hidden-charm pentaquark state with the spin-parity $J^P={\frac{1}{2}}^-$ in details, and calculate the partial decay widths. The total width $Γ(P_c)=14.32\pm3.31\,\rm{MeV}$ is compatible with the experimental value $Γ_{P_c(4312)} = 9.8\pm2.7^{+ 3.7}_{- 4.5} \mbox{ MeV}$ from the LHCb collaboration, and favors assigning the $P_c(4312)$ to be the $[ud][uc]\bar{c}$ pentaquark state with the $J^P={\frac{1}{2}}^-$. The hadronic coupling constants have the relation $|G_{PD^-Σ_c^{++}}|= \sqrt{2}|G_{P\bar{D}^0Σ_c^+}|\gg |G_{P\bar{D}^0Λ_c^+}|$, and favor the hadronic dressing mechanism. The $P_c(4312)$ maybe have a diquark-diquark-antiquark type pentaquark core with the typical size of the $qqq$-type baryon states, the strong couplings to the meson-baryon pairs $\bar{D}Σ_c$ lead to some pentaquark molecule components, and the $P_c(4312)$ maybe spend a rather large time as the $\bar{D}Σ_c$ molecular state.

title: Implicit models of mental disorder across the life-span : a comparison of older and younger adults
Creators: name: Harnett, Hedley
Publisher: name: The Open University
Year: 1996

description: The implicit models of mental disorder held by a group of older adults (n=25) and younger adults (n=28) were examined, using a questionnaire focusing on vignette - case descriptions developed on the basis of previous research in the field. Older and younger adults were found to have highly comparable beliefs and opinions. There were some significant differences between the groups such as in the weight attached to certain causative factors in relation to specific problems and in terms of overall style of causal explanation, where older adults lay greater weight on the role of 'difficulties in personal relationships'. Older adults were also more likely to view inpatient psychiatric treatment as necessary for a number of problems and cited different sources for their views and opinions from younger adults. Clinical implications are discussed and suggestions for further research made.

description: This observational study investigated whether poor performance on the Iowa Gambling Task (IGT) occurs in college students with risk factors for alcohol dependence and/or characteristics of various proposed types of alcohol use disorders. The recent alcohol use group had earlier onset of alcohol problems, more alcohol problems in the past year, impulsivity and illicit drug use than the no recent alcohol group, but these groups did not differ on decision making, psychopathy or family alcoholism history. Nearly all variables were significantly correlated, as expected. No significant correlation was found of family alcoholism history with any other variable, or of impulsivity with recent alcohol use. In the recent alcohol group, poor decision making was not significantly correlated with impulsivity, while in the no recent alcohol group, poor decision making was correlated with impulsivity and psychopathy, but not early alcohol problems or past year alcohol problems. Psychopathy was correlated with past-year alcohol problems among the full group and the recent alcohol use group but not among the no recent alcohol group. Exploratory cluster analysis was conducted on the full data. In the two cluster analysis, the cluster with the poorest decision making also had earlier onset of alcohol problems, and more psychopathy, impulsivity, past-year alcohol problems, and recent alcohol and drug use. In the three cluster solution, the group with most psychopathy had earliest alcohol problems, most alcohol problems in the past year, and most impulsivity, alcohol use and drug use, but had decision making near the mean. Neither the two or three cluster groups differed in family alcoholism history. Similarities were discussed between variable patterns in this sample and proposed typologies of alcoholism.

description: Law sets out the rules for society and the economy, particularly important for interactions between strangers. Legal code is a form of non-rival infrastructure, a public good important for investment and innovation. This paper investigates whether legal code complexity scales with population size in US localities. We analyse a corpus of municipal codes from 3259 cities and measure legal complexity using various metrics, including number of words, bytes, and compressed bytes. We find that legal complexity scales geometrically with jurisdiction population, with a scaling parameter of approximately 0.2 and an R2 of approximately 0.2. The estimated scaling parameter is similar to GDP/capita, consistent with an interpretation of legal codes as regulating social interactions per capita in cities.This article is part of the theme issue ‘A complexity science approach to law and governance’.

description: We revisit Weyl's unified field theory, which arose in 1918, shortly after general relativity was discovered. As is well known, in order to extend the program of geometrization of physics started by Einstein to include the electromagnetic field, H. Weyl developed a new geometry which constitutes a kind of generalization of Riemannian geometry. However, despite its mathematical elegance and beauty, a serious objection was made by Einstein, who considered Weyl's theory not suitable as a physical theory since it seemed to lead to the prediction of a not yet observed effect, the so-called "second clock effect" . In this paper, our aim is to discuss Weyl's proposal anew and examine its consistency and completeness as a physical theory. Finally, we propose new directions and possible conceptual changes in the original work. As an application, we solve the field equations assuming a Friedmann-Robertson-Walker universe and a perfect fluid as its source. Although we have entirely abandoned Weyl's atempt to identify the vector field with the 4-dimensional electromagnetic potentials, which here must be simply viewed as part of the space-time geometry, we believe that in this way we could perhaps be led to a rich and interesting new modified gravity theory.

title: Studies into the rotational history of the minor planets
Creators: name: Hollis, Andrew John
Publisher: name: The Open University
Year: 1996

description: Three aspects of the rotational history of the minor planets are considered - taxonomy, mathematical modelling and observation. Following an introductory review of the basic characteristics and formation, the classification of asteroids is critically assessed and a new scheme based on the spectral characteristics is formulated using numerical taxonomy. It is noted that the asteroids within the basic S-type of other taxonomies can be distributed as two separate zones. the archetypal Juno-type S are found in the middle and outer parts of the main belt whilst a discrete Flora-type S class predominates in the inner portion of the main belt. The groups appear to be two easily distinguishable types probably representing compositional differences. The observed distribution of spin rates for different classes, and hence different surface compositions, is considered. The collision evolution of the spin rates and spin axis orientations has been considered using a new model derived in this work. From this simple model the rotation geometry of precessing bodies can be derived and consideration of the nucleus of Comet Malley suggests that its spin axis is not aligned with any of the geometrical principal axes. Consideration of the geometry of rotation of 1220 Crocus suggests that it might be a binary asteroid. It is found that a random spin axis orientation for the asteroid belt would be expected to be consistent with the observed spin rate distribution. Using the model and the equilibrium shapes of asteroids, calculations have been carried out to investigate the observability of free-precession of asteroids in terms of the maximum light curve amplitude due to free-precession. This shows that only large displacements of the angular velocity vector from the angular momentum vector would produce an amplitude sufficiently great to be detectable. Using a particle in a box model the expected number of examples of free-precession for different sizes of asteroid in the main visible at this time is estimated. New observational data measured as part of this work is presented and analysed. Rotational light curves are examined to determine spin characteristics and whether complex rotations can be seen. As an example new data for 8 Flora has been obtained and, when combined with the digitised information from the international database, has allowed a new model for the shape and variegation to be Proposed by combining the data measured as part of this project with the international data set. From this evidence it is clear that there is no evidence of free precession arising from collisions amongst asteroids in the recent past. In particular it is noted that a shortage of data constrains the accuracy of statistical data and many more quality measurements will be needed before a satisfactory picture of the evolution of minor planets can be presented.

Nonnegotiable lives: International Criminal Justice and the Denial of Black Genocide in Brazil and the United States
Creators: name: Flauzina, Ana
Publisher: name: ProQuest
Year: 2023

description: This dissertation questions the role played by the international criminal justice system in the perpetration of black genocide in Brazil and the United States. While the criminal justice systems of Brazil and the U.S. are the main instruments for the imposition of life-threatening situations surrounding black communities, the international system's indifferent posture endorses the practices of destruction against this social group. This dynamic is supported by a white supremacist arrangement that has detached black suffering from the post-World War II human rights legal postulates, especially during the Cold War era. In this process, the recognition of genocide was framed in strict symbolic racial dimensions. Noticeably, the space of victimization was connected to the violation of white bodies, with the Holocaust being the most important expression of this tendency. The recognition of genocide attached to blacks, such as in the case of Rwanda, is made with an emphasis on the perpetrator and the stereotypical portrayal of the tragedies resulting from the primitive attributes of African populations. However, genocide has remained a category unavailable to characterize the violent attacks of states directly controlled by white elites on black populations. Despite the denunciations of black resistance that stress the existence of black genocide in both countries, the international criminal justice system regulates the interpretation of the crime in a way that prevents its characterization. In reality, there is a judicial administration of genocide, which relies on the issue of intent, working to discredit these claims. Nevertheless, the analysis of the jurisprudence of the ad hoc tribunals allows for the identification of the assaults on blacks in Brazil and the United States as genocide and reveals the political process involved in the recognition of the crime. Considering this framework, the Genocide Convention is analyzed as a human rights instrument that surpasses the limited sphere of criminal law and can be independently assessed to determine the responsibility of the states in the imposition of genocide.

description: Eleven dimensional supergravity compactified on $T^{10}$ admits classical solutions describing what is known as billiard cosmology - a dynamics expressible as an abstract (billiard) ball moving in the 10-dimensional root space of the infinite dimensional Lie algebra E10, occasionally bouncing off walls in that space. Unlike finite dimensional Lie algebras, E10 has negative and zero norm roots, in addition to the positive norm roots. The walls above are related to physical fluxes that, in turn, are related to positive norm roots (called real roots) of E10. We propose that zero and negative norm roots, called imaginary roots, are related to physical branes. Adding `matter' to the billiard cosmology corresponds to adding potential terms associated to imaginary roots. The, as yet, mysterious relation between E10 and M-theory on $T^{10}$ can now be expanded as follows: real roots correspond to fluxes or instantons, and imaginary roots correspond to particles and branes (in the cases we checked). Interactions between fluxes and branes and between branes and branes are classified according to the inner product of the corresponding roots (again in the cases we checked). We conclude with a discussion of an effective Hamiltonian description that captures some features of M-theory on $T^{10}.$

Year: 2023

description: The relationship between undocumented immigrant status (immigrants residing in the United States without legal authorization) and educational outcomes, particularly perceived academic performance and future aspirations, among Latino high school students is investigated. Undocumented status in this study involves the status of students, parents, or significant others. Latino students were recruited from four high schools and a community center. Through semi-structured interviews, participants answered questions about family history, household composition (family structure), school, and future aspirations, among other topics. It is hypothesized that undocumented status will have profound effects on educational outcomes. Results show there is not necessarily a difference in educational outcomes as measured by this study between students with undocumented status or context and those with documented context. However, results suggest differences in future aspirations as well as how students with undocumented status or context versus those without such context experience parental school investments, school motivation, discrimination, deportation fears/fear of ICE (Immigration Customs Enforcement), and disillusionment. Implications for theory, research, and practice are discussed.

description: Quantum communication networks require on-chip transfer and manipulation of single particles as well as their interconversion to single photons for long-range information exchange. Flying excitons propelled by GHz surface acoustic waves (SAWs) are outstanding messengers to fulfill these requirements. Here, we demonstrate the acoustic manipulation of single exciton centers consisting of individual excitons bound to shallow impurities centers embedded in a semiconductor quantum well. Time-resolved photoluminescence studies show that the emission intensity and energy from these centers oscillate at the SAW frequency of 3.5 GHz. Furthermore, these centers can be remotely pumped via acoustic transport of flying excitons along a quantum well channel over several microns. Time correlation studies reveal that the centers emit anti-bunched light, thus acting as single-photon sources operating at GHz frequencies. Our results pave the way for the exciton-based on-demand manipulation and on-chip transfer of single excitons at microwave frequencies with a natural photonic interface.

description: The rice production of Dominican Republic is around half million of TM per year, from which 50% is crops residues (hull and straw). This high production of fiber is used as feed, poultry bedding and organic fertilizer. Taking in account this amount of fiber as a very good of source to produce biogas, ISA University setup two trial of 60 day to evaluate the biogas yields using two substrate of rice crops residues (hulls and straw).The trials consisted of rice hulls and straws treated with urea and rabbit urine or fresh bovine manor under environmental conditions. The Trials had a randomized design, however, the rice hull trials had two treatments and three repetitions and the straws trial had four treatments with three repetition. The evaluated variable was the biogas production (dm3) per kg of DM in 10 d periods. The rice hulls treated with rabbit urine yields about 57.38 dm3 /kg de DM in 60 d and the rice straws treated with rabbit urine and bovine manor yields 98.28 dm3 /kg DM. From theses trials we conclude that it is possible produces a good yields per kg of DM of biogas from rice crops residues with artisanal biodigester

description: We present the first observational confirmation for an extended circumstellar dust disk around epsilon Eri. The observations were obtained with the bolometer array SIMBA at the 15 m radio telescope SEST in Chile and measure the dust continuum at 1.2 mm. The emission, with a total flux of 21.4 mJy and a rms of 2.2 mJy/beam, is resolved to a deconvolved size of 27.4 arcsec which corresponds to 88 AU. No clear indication for a ring-like disk structure is seen, possibly also due to the telescope's large beam width of 24 arcsec. Models of the object's spectral energy distribution from IR to mm-wavelengths show that the emission can also be explained by a simple disk model. We further demonstrate the strong influence of noise and propose to be cautious with interpretations of the ring substructure.

description: En dos zonas con alta prevalencia: Hato Damas (HD, Suroeste) y Mata Larga (ML, Noreste) se desarrollo un programa de control biolôgico clâsico con parasitoides exôticos criados en México. Entre junio y diciembre del 2005, se liberaron 14,690 (HD) o 2,182 (ML) avispitas, respectivamente en alrededor de 20 ârboles de Spondias spp. u otros hospederos en cada area. Durante très periodos consecutivos de fructifïcaciôn hasta Octubre del 2007, se recogieron periôdicamente frutos de ârboles hospederos. En laboratories del IDIAF se registraron las cantidades de frutos, pesos, larvas/pupas obtenidas, emergencia de moscas (especie y sexos), parasitoides nativos y exôticos. En 2007, en la zona de HD se recuperaron parasitoides exôticos en 16 de los 18 lugares muestreados con 1.1a 100% de parasitismo, variando este ùltimo en combination con la especie nativa entre 11.1 y 87.5%. Los exôticos dominaron temporalmente en mäs del 50%) de los lugares muestreados. Emergieron de jobo, ciruela, manzana de oro, guayaba, vinagrillo, carambola, manzana malaya, y almendro tropical. En ML se confirmé el establecimiento de D. areolatus recién fïnalizando el estudio, posiblemente debido a la insufïciente disponibilidad de plantas hospederas de Anastrepha durante el ano entero y la mucho menor cantidad de parasitoides liberados. Se detectaron D. areolatus a 6 km (Suroeste), 7 km (Sureste) y 50 km (Noroeste) desde los lugares de liberation mäs cercanos de HD. Un muestreo realizado en una plantation comercial de guayaba, indica un incremento de parasitismo por D. areolatus durante la temporada hûmeda y reducciôn de infestaciôn de frutos.

description: The red palm mite, Raoiella indica Hirst (Acari: Tenuipalpidae) is an Invasive Alien Species (IAS), which was first detected in the Western Hemisphere in the island of Martinique in 2004. It has since spread to Dominica (2005), Dominican Republic (2006), Puerto Rico (2006), Trinidad (2006), St. Vincent (2007), Jamaica (2007), and Grenada (2007). The pest has the potential to quickly spread to new locations by wind currents or human activities. Raoiella indica was first detected in Trinidad in March 2006. Surveillance activities revealed that the pest was rapidly dispersing to new areas. From July-September 2007, a survey was conducted to detect the presence and distribution of red palm mite and native natural enemies in Trinidad. Ten coconut farms were randomly selected from each of the eight counties and two trees were sampled from each farm. In each case, samples were collected from the 3rd and 9th fronds and examined in the laboratory for red palm mite and natural enemies. The data were analyzed using the Statistical Package for Social Science (SPSS), Version 7.5. Red palm mite was present in all counties, but the numbers observed in each county were varied. Nariva/Mayaro and St. Andrew/St. David had significantly (p<0.05) more mites than the other counties. The predominant natural enemy was Amblyseius largoensis (Acari: Phytoseiidae); however, predatory mite populations were low ranging from only nine in theSt. Patrick East samples to 81 in St. George West. Counties with higher populations were those with large coconut farms >20.0 hectares. Because the red palm mite was found to be widespread, surveys should also be conducted in the dry season and long term population dynamics studies should be initiated. Amblyseius largoensis should be reared and mass produced in the laboratory for augmenting field populations,and classical biological control also should be investigated to manage the pest.

description: We compute the decay constants for the heavy--light pseudoscalar mesons in the quenched approximation and continuum limit of lattice QCD. Within the Schrodinger Functional framework, we make use of the step scaling method, which has been previously introduced in order to deal with the two scale problem represented by the coexistence of a light and a heavy quark. The continuum extrapolation gives us a value $f_{B_s} = 192(6)(4)$ MeV for the $B_s$ meson decay constant and $f_{D_s} = 240(5)(5)$ MeV for the $D_s$ meson.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: In this paper we have investigated an LRS Bianchi I anisotropic cosmological model of the universe by taking time varying $G$ and $Λ$ in the presence of bulk viscous fluid source described by full causal non-equilibrium thermodynamics. We obtain a cosmological constant as a decreasing function of time and for $m, n > 0$, the value of cosmological ``constant'' for this model is found to be small and positive which is supported by the results from recent supernovae observations.

Mindfulness as a Moderator of the Effects of Priming on Mood
Creators: name: Farrow, Victoria A.
Publisher: name: American University

description: Many studies have demonstrated the unconscious nature of information processing, specifically in terms of subliminal priming. Mindfulness, is in part concerned with the ways individuals attend to and react to stimuli. The current study sought to understand whether mindfulness moderates the effect of subliminal priming on mood. My methods involved subliminally priming participants with either a positive or negative mood. Following this, participants completed a number of individual difference measures, including ratings of their present explicit and implicit affect and trait mindfulness. I suggested two (competing) hypotheses regarding explicit reports of mood and facets of mindfulness. First, I hypothesized that participants reporting higher levels of acceptance/nonjudgment would be less affected by the subliminal primes. Alternately, participants reporting higher levels of awareness would be more affected by the primes. Results indicated no interaction effect of acceptance and priming condition on affect. However, I found an interaction effect of awareness and priming. Among those in the negative priming condition, higher levels of awareness were related to less negative affect (i.e., more positive affect), suggesting that those higher in awareness were less affected by the prime. This finding was contrary to my hypothesis (i.e., I predicted that this effect would be found for those higher in acceptance, not awareness). Results from this study suggest that awareness may an important facet in helping to prevent changes in mood from negative stimuli.
