Baryon– Antibaryon Photoproduction off the Proton
Creators: name: Li, Hao
Publisher: name: Carnegie Mellon University
Year: 2023
Subjects: Atomic, Molecular, Nuclear, Particle and Plasma Physics not elsewhere classified

description:  The GlueX Experiment at Jefferson Lab uses linearly polarized photon beam to study the photoproduction of light mesons and baryons off a proton target with unprecedented precision. We have observed pp¯ photoproduction and, for the first time, ΛΛ¯ photoproduction from thresholds up to Eγ = 11.6 GeV. 
We reproduce the observed kinematic distributions with a phenomenological model that includes t-channel Regge exchange and double Regge exchange. The model uses few parameters to match all the kinematic spectra via an optimization algorithm developed specifically for this purpose. 
We report the total cross sections of the two reactions, as well as differen?tial cross sections with respect to various momentum transfers and invariant mass spectra of pp¯, ΛΛ¯, pΛ¯ systems which show enhancements right above pro?duction thresholds. Furthermore, the beam asymmetries of the pp¯ system are extracted from the GlueX data to further probe the nature of the t-channel Regge exchanges. We also report preliminary measurements of the spin polarizations of the individual hyperons.
 No prominent resonance structure was found in these reaction channels, but the angular distributions and the correlation of longitudinal momenta indicate the existence of multiple production mechanisms. Besides a dominant forward peak in the polar angle of the baryon-antibaryon pair in t-channel production, we see wide-angle antibaryon distributions different from that of the baryon. In the hyperon channel, we see a clear separation between the photoproduction of the ΛΛ¯, pΛ¯ systems
Molecular phylogeny of the goldenasters, subtribe Chrysopsidinae (Asteraceae: Astereae), based on nuclear ribosomal and chloroplast sequence data

Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: In this study, phylogenies were estimated based on molecular data from ETS and ITS, nuclear ribosomal DNA, and ycf1 and psbA-trnH, chloroplast DNA for all known genera of the Chrysopsidinae. The resulting phylogenies were used as the basis for addressing questions related to subtribal and generic monophyly, the relationship of the Central and South American genera Osbertia, Tomentaurum, and Noticastrum to North American genera, biogeography, morphological trait evolution and convergence among morphological features commonly used to delimit generic and species boundaries. Additionally, modifications to commonly used DNA extraction techniques allowed us to access DNA from relatively old herbarium specimens. Results from analyses of individual and combined datasets support the monophyly of the Chrysopsidinae and allowed some resolution of both the relationships among the genera of the Chrysopsidinae and the relationships among sections of the genus Heterotheca.

Bone conduction equal loudness contours at different placements, conditions, and intensities
Creators: name: Arvindekar, Sanghmitra
Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: Bone conduction transmission has been studied for decades; however, equal loudness contours for bone conduction have not been established. The purpose of the current study was to establish bone conduction equal loudness contours at two different placements (mastoid and condyle), in two different conditions (unilateral and bilateral) and at two different intensities (20 and 40 dB HL). The study included three parts, soundfield equal loudness contours, soundfield to bone conduction loudness comparisons and bone conduction equal loudness contours. Results showed that there was no difference between any of the conditions or placements for bone conduction equal loudness contours. Also, the bone conduction equal loudness values closely matched the published ISO values established with a 1000 Hz reference at 20 and 40 dB HL.

Mentoring in higher education: an evaluation of the SAGE mentoring program and its relation to implicit intelligence theories
Creators: name: Travers, Christopher
Publisher: name: Maryland Shared Open Access Repository
Year: 2011

description: More African Americans are in college than ever before, but these students still lag  behind their white counterparts in every major area of academic achievement. The  disparity between African American and White students is known as the achievement  gap. Colleges have tried to improve this gap by providing students with mentoring and  educational assistance programs. The purpose of this study was to evaluate the  effectiveness of one mentor program, (SAGE), on achievement in terms of Grade Point  Average. It was expected that implicit intelligence theories would moderate the  relationship between SAGE participation and GPA. A hierarchical regression analysis  was run in order to examine the interaction between SAGE and implicit intelligence  theories. Results showed no significant main effects or interaction.

The effect of skin tone on perceptions of competence and warmth among African-Americans
Creators: name: Aklilu, Lelise
Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: Several studies have outlined the impact of skin tone bias on the Black community in America. The purpose of the current study was to examine the effect of skin tone bias through the lens of the stereotype content model (SCM), which states that stereotypes have competence and warmth dimensions. According to the SCM, a target can be rated high on one dimension and low on the other, but never high on both dimensions. Sixty-two Black students from Towson University completed surveys rating various light- and dark-skinned male and female targets on their competence and their warmth. It was found that dark-skinned targets were perceived as being warmer and more competent than light-skinned targets. The results indicated that the stereotype content model may not apply to the study of skin tone bias. Future studies should pursue other methods of studying perceptions of competence and warmth among Black Americans.

description: A generalized linear sigma model for low energy QCD is employed to study the quark structure of eight low lying scalar isomultiplets as well as eight low lying pseudoscalar isomultiplets. The model, building on earlier work, assumes the possible mixing of quark anti-quark states with others made of two quarks and two antiquarks. No {\it a priori} assumption is made about the quark contents of the states, which emerge as predictions. An amusing and contrasting pattern for the quark structure is found; the lighter conventional pseudoscalars are, as expected, primarily of two quark type whereas the lighter scalars have very large four quark admixtures. The new feature of the present paper compared to earlier ones in this series involves the somewhat subtle and complicated effects of SU(3) flavor breaking. They do not alter the general pattern of two quark vs. four quark mixing obtained in the SU(3)symmetric case but, of course, give a more detailed picture.

Women with beards and men in frocks: gender nonconformity in American modern film
Creators: name: Kronz, Victoria E.
Publisher: name: Maryland Shared Open Access Repository
Year: 2013

description: The present study examines the portrayal of gender nonconformity in 36 American films released between 2001-2011. Mainstream and independent films with at least one character portrayed in a gender transgressive way were chosen for analysis. The films were coded at two levels: (1) the entire film, and (2) individual characters. The entire films were coded for mainstream versus independent production, genre, and screen time of gender nonconforming characters. The characters were coded for type of gender transgression, character demographics and the purpose in the plot. The most common purpose of the non-conforming characters was humor, especially in mainstream films. Exploring identity was a much less common purpose and these films were far more likely to be independent films. The non-conforming characters were far more likely to identify as a static identity, man or woman, rather than anything else.

description: An infinitely thin solenoid carrying magnetic flux Phi (a `Dirac string') inserted into an ordinary band insulator has no significant effect on the spectrum of electrons. In a strong topological insulator, remarkably, such a solenoid carries protected gapless one-dimensional fermionic modes when Phi=hc/2e. These modes are spin-filtered and represent a distinct bulk manifestation of the topologically non-trivial insulator. We establish this `wormhole' effect by both general qualitative considerations and by numerical calculations within a minimal lattice model. We also discuss the possibility of experimental observation of a closely related effect in artificially engineered nanostructures.

?I don?t really compare to the ideal?: objectification theory and the effects on sexual behavior and communication
Creators: name: Kernan, Kaitlin
Publisher: name: Maryland Shared Open Access Repository
Year: 2013

description: The present study considered the ways in which women described their sexual experiences and communication with men from the framework of objectification theory. Objectification theory refers to viewing women as sexual objects. The data was collected from 148 heterosexual women, between the ages of 18-24. Participants completed an anonymous online survey that took about 23-30 minutes. This survey included both open-ended and closed ended questions, along with two different questionnaires. The data showed both negative and positive perceptions from sexual objectification and self-objectification. Low body image was apparent in almost ? of the participants. Compartmentalization was common in most responses. That is, there were both negative and positive attitudes towards specific body parts; these parts commonly being socially sexualized anatomy like breasts, buttocks, and stomach. Although some respondents found communicating sexually difficult, most did not allow their lack of self-confidence to hinder communication.

description: Bereits die Umschlaggestaltung des zu rezensierenden Übungsheftes verweist auf seine enge Verbindung mit dem 2003/2004 in erster Auflage erschienenen Lehrwerk Themen aktuell des Hueber-Verlags. Themen aktuell, das in drei Bänden zur Niveaustufe B 1 gemäß dem Europäischen Referenzrahmen führt, enthielt in seiner ursprünglichen Konzeption keine gesonderten phonetischen Übungen. Diesem zu Recht vom Verlag bemerkten Mangel soll mit der Herausgabe dieses Zusatzheftes abgeholfen werden. Die Idee - so heißt es im Vorwort - entstand "aus der Erfahrung im Deutschunterricht im In- und Ausland: Es fehlte an praktischem Übungsmaterial gerade für die Grundstufe" (5). Dass phonetische Übungen generell ein wichtiger Bestandteil jeglichen Fremdsprachenunterrichts, also auch des DaF-Unterrichts, sein sollten, darüber besteht mittlerweile breite Einigkeit. Allein die Art der Vermittlung phonetischer Kenntnisse und vor allem Fertigkeiten ist zuweilen umstritten. Soll Phonetik in einem gesonderten Kurs unterrichtet werden oder sollen phonetische Übungen in die Progression des benutzten Kursbuches integriert werden? Die Beantwortung dieser Frage hängt sicherlich zum einen vom Lernziel und von der jeweiligen Niveaustufe ab, zum anderen aber auch von der Zusammensetzung der Gruppe: Sind die Gruppen muttersprachlich homogen oder gemischt?
Structure and properties of copper infiltrated iron.
Creators: name: Krantz, Tibor
Publisher: name: University of British Columbia
Year: 2011

description: Two-phase composites have been prepared by infiltrating sintered iron compacts with liquid copper. The effects have been studied of iron particle size, matrix mean free path, and the volume fraction and micro-hardness of the iron-rich constituent, on the tensile properties of composites. It has been found that the strength of the composites is related to the amount of solution hardening of the iron component during infiltration. The results of tensile tests have suggested that the hardness of the iron-rich constituent is the dominant factor controlling yield strength, ultimate tensile strength and elongation. However, the ultimate strength has been found to depend also on the volume fraction of the hard constituent, and elongation has also been found to be a function of the interface area.

Assessing climate change effects on competitive interactions of the federally endangered Shenandoah salamander (Plethodon shenandoah)
Creators: name: Dallalio, Eric A.
Publisher: name: Maryland Shared Open Access Repository
Year: 2013

description: The Shenandoah salamander (Plethodon shenandoah) is a federally endangered species with a restricted distribution at high elevation in Shenandoah National Park, presumably limited by competition with the red-backed salamander (Plethodon cinereus). Recent research suggests that climate change may exacerbate interspecific competitive interactions at a cost to P. shenandoah. An effort to evaluate P. shenandoah extinction risk and management options identified uncertainties that must be addressed in order to make a management decision, including the response of P. shenandoah to climate change. I investigated the influence of climate on competitive interactions in 3- dimensional mesocosms that mimicked realistic habitats in two phases: (1) a pilot study to ensure the suitability of the experimental venue, and (2) a primary study to investigate the response of P. shenandoah to competition with P. cinereus under two future climate scenarios. The results suggest that core P. shenandoah populations may decline in response to increasing temperatures, particularly if their habitat is getting warmer and drier, though range expansion may occur in areas where it competes with P. cinereus.

Conforming to misinformation: an exploration of attractiveness and confidence
Creators: name: Joseph-David, Jacob
Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: Witness testimony is a key factor used when convicting criminals, yet these testimonies are not always completely accurate. Often times, witnesses use the time after the crime to discuss the specifics of the crime with the other co-witnesses. This post event information (PEI), when inaccurate, can lead to the distribution of misinformation among the witnesses. It is clear that misleading PEI is one of the leading causes for conformity to false memories in witnesses. The current study focuses on the effect of two social factors, confidence and attractiveness, on conformity to misinformation. Participants viewed a video of a crime taking place, followed by one of four videos of a co-witness's memory of that crime with 10 pieces of misinformation. After the completion of both videos the participants? memory was tested using a cued recall memory test. The four videos featured an actress dressed attractively or unattractively, and she spoke confidently or unconfidently. Participants conformed more and had more confidence in their answers when information was presented by an attractive witness. Additionally, participants had more accurate memories when the PEI was presented by a confident witness, they also had higher confidence in their correct answers.

description: Während meiner Berufstätigkeit als chinesischer Deutschlehrer in den letzten Jahren habe ich oft feststellen müssen, daß gewisse deutsche Passivkonstruktionen chinesischen Studenten schwer zu schaffen machen. Es handelt sich dabei nicht nur um das Gefüge werden + Partizip II. Es sind auch sogenannte Konkurrenzformen des Passivs, die den meisten Lernenden viel Kopfzerbrechen bereiten. Bei der Auseinandersetzung mit passivischen Konstruktionen wie bekommen/erhalten/kriegen + Part. II, gehören + Part. II oder bleiben + Part. II wissen sich die Lerner häufig nicht zu orientieren. Daß die Lernenden solche Passiv-Sätze nur schwer in den Griff bekommen, ist anscheinend zum größten Teil auf strukturelle Unterschiede zwischen dem Deutschen und dem Chinesischen zurückzuführen, wobei die Kasuslosigkeit des Chinesischen eine ausschlaggebende Rolle spielen dürfte. Durch die oben beschriebenen Erfahrungen veranlaßt, soll mit der vorliegenden Arbeit eine Untersuchung der deutschen Passivkonstruktionen unter dem Aspekt der Kontrastierung mit chinesischen Passivformen unternommen werden, um die sich dabei ergebenden Parallelitäten und vor allen Dingen Diskrepanzen zwischen den beiden Sprachen in diesem Punkt weiter didaktisch zu nützen. Es sei darauf hingewiesen, daß aus Platzgründen lediglich einige formale und inhaltliche Kriterien für eine erste Systematisierung der in der Arbeit mit dem Etikett 'Passiv' versehenen verbalen Gefüge in den beiden Sprachen gegeben werden können.

description: We demonstrate the implementation of a spin qubit with a single Ca ion in a micro ion trap. The qubit is encoded in the Zeeman ground state levels mJ=+1/2 and mJ=-1/2 of the S1/2 state of the ion. We show sideband cooling close to the vibrational ground state and demonstrate the initialization and readout of the qubit levels with 99.5% efficiency. We employ a Raman transition close to the S1/2 - P1/2 resonance for coherent manipulation of the qubit. We observe single qubit rotations with 96% fidelity and gate times below 5mus. Rabi oscillations on the blue motional sideband are used to extract the phonon number distribution. The dynamics of this distribution is analyzed to deduce the trap-induced heating rate of 0.3(1) phonons/ms.
Effects of Reinforcement and Punishment on Attitude Formation

Publisher: name: Maryland Shared Open Access Repository
Year: 2012

description: Peoples? attitudes may frequently be predicted by the attitudes of their peers or salient individuals of higher status. Previous research focuses on elaborative conditioning to explain this effect. The present study elaborates on this previous research by examining the role of reinforcement and punishment on attitude formation, and creating a paradigm that more accurately reflects real world interaction between the individual and his or her family members and peers. Participants expressed their opinions regarding a candidate running for a position in their university?s student government. They received feedback that they were told came from graduate students, and were then given the opportunity to change their opinions. There was significantly more change in participants who received punishment as opposed to those who received reinforcement or the control group. However, rather than causing participants to change their minds, this punishment seemed to have a polarizing effect, causing participants who opposed the candidate to form a stronger opposition.

description: X-ray data analysis have found that fairly complex structures at cluster centres are more common than expected. Many of these structures have similar morphologies, which exhibit spiral-like substructure. It is not yet well known how these structures formed or are maintained. Understanding the origin of these spiral-like features at the centre of some clusters is the major motivation behind this work. We analyse deep \textit{Chandra} observations of 15 nearby galaxy clusters (0.01 $ < z < $ 0.06), and use X-ray temperature and substructure maps to detect small features at the cores of the clusters. We detect spiral-like features at the centre of 7 clusters: A85, A426, A496, Hydra A cluster, Centaurus, Ophiuchus, and A4059. These patterns are similar to those found in numerical hydrodynamic simulations of cluster mergers with non-zero impact parameter. In some clusters of our sample, a strong radio source also occupies the inner region of the cluster, which indicates a possible connection between the two. Our investigation implies that these spiral-like structures may be caused by off-axis minor mergers. Since these features occur in regions of high density, they may confine radio emission from the central galaxy producing, in some cases, unusual radio morphology.

Publisher: name: Maryland Shared Open Access Repository
Year: 2013

description: The first part of this study included stormwater sampling from highway bridges. The second part of the project evaluated media to remove metals in the presence of salt. Media tested included eleven adsorptive materials. Batch tests were conducted with three levels of salt (none, 2.5, 5 g/L NaCl) mixed with a standard combination of metals (Cu, Zn, Pb, Ni, Cr) based on the values found in highway bridge runoff sampled. The third part was a column study designed to represent field conditions. Three media were tested with the same stormwater treatments. Effluent was compared based on salt levels and media type to identify the media with the best ability to absorb metals in the presence of salt. It was determined that Imbrium 10, a mixture of aluminum and iron oxides and fine sand, had the highest absorption capacity for zinc and copper in the presence of salt.

description: The mass of super massive black holes at the centre of galaxies is tightly correlated with the mass of the galaxy bulges which host them. This observed correlation implies a mechanism of joint growth, but the precise physical processes responsible are a matter of some debate. Here we report on the growth of black holes in 400 local galactic bulges which have experienced a strong burst of star formation in the past 600Myr. The black holes in our sample have typical masses of 10^6.5-10^7.5 solar masses, and the active nuclei have bolometric luminosities of order 10^42-10^44erg/s. We combine stellar continuum indices with H-alpha luminosities to measure a decay timescale of ~300Myr for the decline in star formation after a starburst. During the first 600Myr after a starburst, the black holes in our sample increase their mass by on-average 5% and the total mass of stars formed is about 1000 times the total mass accreted onto the black hole. This ratio is similar to the ratio of stellar to black hole mass observed in present-day bulges. We find that the average rate of accretion of matter onto the black hole rises steeply roughly 250Myr after the onset of the starburst. We show that our results are consistent with a simple model in which 0.5% of the mass lost by intermediate mass stars in the bulge is accreted by the black hole, but with a suppression in the efficiency of black hole growth at early times plausibly caused by supernova feedback, which is stronger at earlier times. We suggest this picture may be more generally applicable to black hole growth, and could help explain the strong correlation between bulge and black hole mass.

description: The present work proposes a discussion on the self-energy of charged particles in the framework of nonlinear electrodynamics. We seek magnet- ically stable solutions generated by purely electric charges whose electric and magnetic fields are computed as solutions to the Born-Infeld equa- tions. The approach yields rich internal structures that can be described in terms of the physical fields with explicit analytic solutions. This suggests that the anomalous field probably originates from a magnetic excitation in the vacuum due to the presence of the very intense electric field. In addition, the magnetic contribution has been found to exert a negative pressure on the charge. This, in turn, balances the electric repulsion, in such a way that the self-interaction of the field appears as a simple and natural classical mechanism that is able to account for the stability of the electron charge.

description: The semiclassical path integral method has been applied for studying spin relaxation in a narrow 2D strip with the Rashba spin-orbit interaction. Our numerical calculations show a good agreement with the experimental data, although some features of experimental results are not clear yet. We also calculated the relaxation of a uniform spin-density distribution in the ballistic regime of very narrow wires. With the decreasing wire width, the spin polarization exhibits a transition from the exponential decay to the oscillatory Bessel-like relaxation. The SPI method has been also employed to calculate the relaxation of the particularly long-lived helix mode. A good agreement has been found with calculations based on the diffusion theory.

description: Stable, accurate, divergence-free simulation of magnetized supersonic turbulence is a severe test of numerical MHD schemes and has been surprisingly difficult to achieve due to the range of flow conditions present. Here we present a new, higher order-accurate, low dissipation numerical method which requires no additional dissipation or local "fixes" for stable execution. We describe PPML, a local stencil variant of the popular PPM algorithm for solving the equations of compressible ideal magnetohydrodynamics. The principal difference between PPML and PPM is that cell interface states are evolved rather that reconstructed at every timestep, resulting in a compact stencil. Interface states are evolved using Riemann invariants containing all transverse derivative information. The conservation laws are updated in an unsplit fashion, making the scheme fully multidimensional. Divergence-free evolution of the magnetic field is maintained using the higher order-accurate constrained transport technique of Gardiner and Stone. The accuracy and stability of the scheme is documented against a bank of standard test problems drawn from the literature. The method is applied to numerical simulation of supersonic MHD turbulence, which is important for many problems in astrophysics, including star formation in dark molecular clouds. PPML accurately reproduces in three-dimensions a transition to turbulence in highly compressible isothermal gas in a molecular cloud model. The low dissipation and wide spectral bandwidth of this method make it an ideal candidate for direct turbulence simulations.

description: This paper proposes new tests of conditional independence of two random variables given a single-index involving an unknown finite-dimensional parameter. The tests employ Rosenblatt transforms and are shown to be distribution-free while retaining computational convenience. Some results from Monte Carlo simulations are presented and discussed.

title: Motiviert für Deutsch? Eine qualitative Studie zum Anfängerunterricht DaF in Norwegen
Creators: name: Lindemann, Beate
Publisher: name: Universitäts- und Landesbibliothek Darmstadt
Year: 2023

description: In den letzten Jahren lernen immer weniger norwegische Schüler Deutsch als zweite Fremdsprache, und diejenigen, die Deutsch lernen, geben oft schon im Laufe des ersten Unterrichtsjahres auf. Der vorliegende Aufsatz präsentiert eine Studie, die norwegische Deutschlernanfänger während ihres ersten Unterrichtsjahres begleitet hat. Dabei stand die Entwicklung der Schülermotivation während des Unterrichtsjahres im Zentrum der Untersuchung. Es zeigt sich, dass vor allem fehlende altersgerechte und für die Schüler nachvollziehbare Informationen zur "Nützlichkeit" von deutschen Sprachkenntnissen und die Rahmenbedingungen des Deutschunterrichts zur Reduktion der Sprachlernmotivation beitragen.

description: Als Fachfrau aus der Praxis bin ich immer wieder auf der Suche nach neuen Lehrwerken, die sich mit der Vermittlung von Grammatik beschäftigen. Insbesondere, wenn es sich um solche Lehrwerke handelt, die vorgeben, neue Wege zu beschreiten. So wurde ich neugierig auf das Buch von Michaela Brinitzer und Verena Damm mit dem Titel Grammatik sehen - Arbeitsbuch für Deutsch als Fremdsprache. Verbunden mit der Hoffnung, neue Ideen für meinen Unterricht zu erhalten, studierte ich das Buch näher. Um das Ergebnis etwas vorwegzunehmen: Leider wurden meine Erwartungen enttäuscht. Warum? Darauf gehe ich gleich im Einzelnen ein.
title: DaF (L3) via Englisch (L2) in Japan (L1): Attraktivitätsfaktoren und Erfolgsgaranten beim Deutschlernen in Japan
Creators: name: Guido, Oebel
Publisher: name: Universitäts- und Landesbibliothek Darmstadt
Year: 2023

description: Dieser Beitrag versteht sich als Plädoyer für L2—i.d.R. Englisch—als Eselsbrückensprache im universitären L3 DaF-Unterricht in Japan, und zwar immer dort und dann, wenn L2-Vorwissen den Deutschlernenden den L3-Zugang und das -Verständnis erleichtert. Dabei geht es keineswegs darum, "isolierte Sprachbrocken aus dem Englischen als Verstehensinseln zu nutzen", sondern im Sinne einer systematisierten Mehrsprachendidatik aufgrund vorgängiger Spracherfahrungen synergetische Lerneffekte zu schaffen (Krumm 2003: 47; s. Literaturverzeichnis am Ende des Beitrags). Nicht minder wichtig für einen u.a. Attraktivitätszuwachs des DaF-Unterrichts in Japan— und anderswo—erachte ich die das Rollenverständnis der Lehrkraft sowie die jeweils praktizierte Fremdsprachenlehrmethode. Da es aufgrund der geographischen Ferne des Zielsprachenlandes außerhalb des DaF-Unterrichts zwangsläufig an entsprechender Immersion im Lernerland mangelt, muss der deutsche Sprechanteil der Lerner im Unterricht erhöht werden. Dazu prädestiniert ist m.E. Jean-Pol Martins in höchstem Maße lernerinvolvierendes Lernen-durch-Lehren, das den Redeanteil der Lerner auf 80 Prozent zu steigern imstande ist, bei gleichzeitiger Reduzierung dessen der Lehrkraft auf 20 Prozent. Dass dies mit einer Neudefinierung der Lehrerrolle einhergeht, ist offensichtlich.

title: Issues surrounding trilingual families: Children with simultaneous exposure to three languages
Creators: name: Barron-Hauwaert, Suzanne
Publisher: name: Universitäts- und Landesbibliothek Darmstadt
Year: 2023

description: Trilingualism is generally treated in the relevant literature as another type of bilingualism, and theories and findings from studies of bilinguals are often assumed to be applicable to trilinguals by extension. Trilingualism is frequently explained briefly as a special phenomenon of bilingualism, using special cases of brain-damaged trilinguals who recover all three languages, or of young children who are precociously trilingual. There are many types of trilinguals: children growing up in a trilingual environment, adults living in a trilingual or multilingual community, and fluent bilinguals who have learned a third language at school or for other reasons. Most of these types do not have much choice of whether they wish to be trilingual; it is simply a fact of their particular circumstances. How they deal with three languages is interesting in that the three languages (or cultures) cannot be 'balanced' or equal, as they can be in a bilingual person.

description: Bien qu’au Japon, certains professeurs de français de langue maternelle française aient tendance à ignorer l’anglais, la plupart d’entre eux comparent sans doute fréquemment le français à l’anglais. Cependant, ils se peut qu’ils ne soient pas en mesure de tirer de ces constantes comparaisons tout le profit qu’ils pourraient en faire s’ils les basaient sur un manuel qui organise cette comparaison de manière systématique, et s’ils se plaçaient du point de vue d’un locuteur japonais. Basé sur cette hypothèse, le présent travail répertorie et tente de donner un aperçu de tous les manuels récemment publiés en japonais qui comparent le français à l’anglais, afin d’attirer sur ces ouvrages l’attention des professeurs de français, et spécialement ceux de langue maternelle française.

description: We have systematically investigated the effect of oxidation on the structural and electronic properties of graphene based on first-principles calculations. Energetically favorable atomic configurations and building blocks are identified, which contain epoxide and hydroxyl groups in close proximity with each other. Different arrangements of these units yield an LDA band gap over a range of a few eV. These results suggest the possibility of creating and tuning the band gap in graphene by varying the oxidation level and the relative amount of epoxide and hydroxyl functional groups on the surface.
