description: We use first principles calculations to investigate the lattice properties of group-IV monochalcogenides. These include static dielectric permittivity, elastic and piezoelectric tensors. For the monolayer, it is found that the static permittivity, besides acquiring a dependence on the interlayer distance, is comparatively higher than in the 3D system. In contrast, it is found that elastic properties are little changed by the lower dimensionality. Poisson ratio relating in-plane deformations are close to zero, and the existence of a negative Poisson ratio is also predicted for the GeS compound. Finally, the monolayers shows piezoelectricity, with piezoelectric constants higher than that recently predicted to occur in other 2D-systems, as hexagonal BN and transition metal dichalcogenide monolayers.
Relationship between muscle stiffness of the superficial shoulder musculature and subacromial space distance
Creators: name: Young, Pamela

Year: 2014

description: Side-to-side differences in subacromial space distance, muscle stiffness, and pectoralis minor length (PML) and the predictive ability of these physical characteristics to predict subacromial space distance in overhead athletes were investigated. Fifty collegiate overhead athletes completed one testing session of bilateral measurements of the subacromial space distance, muscle stiffness, and PML. The dominant arm exhibited a shorter PML (p=0.02) and greater stiffness of the teres minor (1.50kg: p<0.005; 1.75kg: p<0.005; 2.0kg: p<0.005), posterior deltoid (1.50kg: p<0.005; 1.75kg: p=0.02; 2.0kg: p<0.005), and lower trapezius (1.50kg: p=0.04; 1.75kg: p=0.03; 2.0kg: p=0.03) compared to the non-dominant arm. Neither stiffness nor PML predicted subacromial space distance in either limb of healthy overhead athletes. These side-to-side differences could provide clinicians with a screening tool to identify individuals with asymmetries. Further research is needed to determine the relationship between stiffness of the superficial shoulder musculature and subacromial space distance in overhead athletes with subacromial impingement syndrome.

description: Violation of Lorentz invariancy in the high energy quantum gravity motivates one to consider an energy dependent spacetime with massive deformation of standard general relativity. In this paper, we take into account an energy dependent metric in the context of a massive gravity model to obtain exact solutions. We investigate the geometry of black hole solutions and also calculate the conserved and thermodynamic quantities, which are fully reproduced by the analysis performed with the standard techniques. After examining the validity of the first law of thermodynamics, we conduct a study regarding the effects of different parameters on thermal stability of the solutions. In addition, we employ the relation between cosmological constant and thermodynamical pressure to study the possibility of phase transition. Interestingly, we will show that for the specific configuration considered in this paper, van der Waals like behavior is observed for different topology. In other words, for flat and hyperbolic horizons, similar to spherical horizon, a second order phase transition and van der Waals like behavior are observed. Furthermore, we use geometrical method to construct phase space and study phase transition and bound points for these black holes. Finally, we obtain critical values in extended phase space through the use of a new method.

A Literatura Infantil como oportunidade de abordagem aos valores na Educação Pré-Escolar
Creators: name: Ferreira, Ana Filipa
Publisher: name: Aprender
Year: 2013

description: A globalização fez emergir um conjunto de paradigmas sociais, económicos e culturais que alteraram por completo o mundo que costumávamos conhecer. A realidade contemporânea é verdadeiramente complexa, mas impôs-se de uma forma demasiado rápida e até agressiva, o que nos impede de a compreender de forma ampla. Neste contexto, os valores que costumavam defi nir-nos enquanto indivíduos e enquanto cidadãos vêm perdendo a sua nitidez, gerando uma dificuldade crescente em percebermos como orientar as nossas condutas. Perante esta perigoso panorama, urge a necessidade de a Escola assumir a sua responsabilidade fundamental de formar cidadãos esclarecidos, ativos e responsáveis. Só através de um processo de constante refl exão sobre si própria, sobre o outro e sobre os diversos modos de agir, em que o pensamento crítico seja sempre valorizado, a criança poderá desenvolver-se de forma plena, formando a sua identidade com clareza e aprendendo a lidar com a alteridade de forma harmoniosa. Particularmente no Jardim de Infância, a Literatura Infantil assume-se, pela sua riqueza estética e literária, mas também pela relação tão singular que se forma entre a criança e o livro, como um meio de excelência para a abordagem e a refl exão sobre os valores.

Thinking outside the (wooden) box: a rhetorical analysis of the ethical complexity of the Uncle Jack statue
Creators: name: Klobucar, Gretchen Victoria
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: The life-sized bronze statue variously known as Uncle Jack or the Good Darky has been subject to protests and numerous relocations. Currently located in Baton Rouge, Louisiana at the Louisiana State University Rural Life Museum, the statue continues to be a source of controversy as an artifact with shifting use and value over the last 84 years. Based on the statue's sculptured body, the wooden box covering the original inscription, and the interpretive placard, I argue that the ethical complexity of past racial relations and the racial anxiety the statue continues to provoke are framed by the museum either as problems of the past or as problems deferred indefinitely to the future. This critical analysis assesses the rhetorical and ethical consequences of the statue and the way the museum has framed it, and demonstrates why prescriptions to destroy the statue are ill-considered.

description: On trouve dans la littérature pour la jeunesse, en particulier lorsqu’elle s’ouvre à d’autres cultures, un endroit pour lire et comprendre le monde, dans sa mouvance, sa richesse, sa diversité et sa différence. Okilélé et L’Enfant Océan sont deux oeuvres françaises de la fi n du XXe siècle. Okilélé est un album illustré écrit pour de très jeunes lecteurs, tandis que la lecture de L’Enfant Océan est recommandée à partir de onze ans par l’éditeur. Chacune des deux histoires s’inscrit dans une société donnée, à une époque donnée. Dans la famille ou dans la société, les valeurs, tout comme la représentation de soi et de l’autre, sont des thèmes communs aux deux oeuvres, qui posent en particulier la question de la différence.

description: We exam the pairs of neutrino mixing matrix and suggest pairs that can be used in the construction of new mixing patterns, with "pair" denoting the equality of the modulus of a pair of matrix elements. The results show that the tri-maximal mixing in $ν_2$ and the $μ$-$τ$ interchange symmetry are good choices under current experimental results. The two cases of bi-pair mixing pattern depend on the mass hierarchy of neutrinos. We also derive constraints on the CP-phase by the pairs. The results are compatible with the maximal CP-violation in most cases that are both self-consistent and consistent with experimental results.

O documento prevê o trabalho com temas transversais, um conjunto de assuntos que devem ser trabalhados na escola, porque expressam valores e conceitos de cidadania, bem como são temáticas de abrangência e urgência para a sociedade brasileira atual. Com base nisso, analisamos duas seções da revista infantojuvenil Ciência hoje das crianças de 2011, “Baú de histórias” e “Poesia e companhia”, as quais apresentam textos literários, no intuito de averiguar a possibilidade de se trabalhar temas transversais a partir desses textos. Percebeu-se que essa proposta é viável, ou seja, o texto literário, além de promover a refl exão crítica e colocar o aluno em contato com aqueles direitos que, consoante Candido (1995), são imensuráveis, alimentam a alma, e pode ser uma ferramenta para adentrar na temática transversal, propiciando a formação de um leitor competente.

description: An extension of polar codes is proposed, which allows some of the frozen symbols, called dynamic frozen symbols, to be data-dependent. A construction of polar codes with dynamic frozen symbols, being subcodes of extended BCH codes, is proposed. The proposed codes have higher minimum distance than classical polar codes, but still can be efficiently decoded using the successive cancellation algorithm and its extensions. The codes with Arikan, extended BCH and Reed-Solomon kernel are considered. The proposed codes are shown to outperform LDPC and turbo codes, as well as polar codes with CRC.

Question driven harmonisation of data – The variable cascade in practice
Creators: name: Johnson, Jon

Publisher: name: Zenodo
Year: 2020

description: Harmonisation of data is largely a manual process. Although there are naming conventions that are embedded in many studies (especially panel studies), that can provide strong clues to the equivalence of variables, it is by no means perfect and requires a priori knowledge. The capture of questions (in DDI-Lifecycle instruments) linked to the output variables, allows generic methods to be developed to reliably identify and organise variables which may be candidates for harmonisation. The presentation will discuss the approach CLOSER has taken to develop user facing tools that allows researchers to determine the criteria they wish to apply to harmonising variables, these include, the question, response domain, mode, and study characteristics.

What Do Social Desirability Scales Measure? The Association between Social Desirability & Response Styles.
Creators: name: Kapousouz, Evgenia
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Public administrators and policymakers rely on self-reported data in order to gauge public opinion and act accordingly. However, survey data are subject to survey errors. One source of error is social desirability responding. Researchers commonly use social desirability scales to exclude respondents from the analysis or identify participants who provide lower quality data. However, because of how these scales are constructed, the measurement of SDR via these scales may also be associated with other response biases such as acquiescence, disacquiescence, and extreme response style. Specifically for extreme response style, I also examine whether different measurement of social desirability affects the association between social desirability and extreme response style. The primary purpose of the dissertation is to investigate whether item-specific response scales reduce the association. Secondary analysis shows that there is an association between social desirability, disacquiescence, and extreme response style. However, different measurement of social desirability decreases the association with extreme response style. Then, I conducted a within-subjects experiment to identify whether item-response option increase data quality. The original response scales yielded results consistent with previous chapters, revealing no association between social desirability and acquiescence, but a significant association between social desirability and both disacquiescence and extreme response style. The association between social desirability, disacquiescence, and extreme response style persisted even with item-specific scales. However, different coding of the scales reduced the association between social desirability and extreme response style.

Os defi cientes na Literatura Infantil – tendências e representações

description: O artigo discute a articulação tradicional entre literatura para crianças e pedagogia, a partir da análise de 27 obras infantis publicadas no Brasil nos anos 2000, as quais apresentam personagens com defi ciências: surdos, cegos e cadeirantes. A análise permitiu identifi car duas tendências principais: a tematização da defi ciência como o nó narrativo das histórias, de um lado, e a utilização de personagens defi cientes em enredos que focalizam outras questões, de outro lado. Nos livros alinhados com a primeira tendência, predomina a retórica da compensação e da superação. Já na segunda, há um investimento estético cuidadoso para inserir a temática de forma sutil e não diretiva, mais aberta à polissemia. No caso das obras sobre surdos, algumas adotam uma visão clínica e outras incorporam a concepção atual de cultura surda. Observa-se, assim, que, apesar da intencionalidade pedagógica dominante na maioria dessas obras, algumas fogem a tal padrão, mobilizando o leitor para cooperar ativamente com a construção de diferentes interpretações para o texto verbal e as imagens.

International debate over the use of glyphosate in Colombia: a study of environmental journalism
Creators: name: Fernández, Julia Isabel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: This study examined the coverage of two newspapers—Colombia's El Tiempo and the New York Times—of the debate over the use of the chemical herbicide glyphosate to eradicate illegal crops in Colombia. The findings suggest that both publications failed to provide significant details about the herbicide's chemical formula and its secondary effects. The analysis also corroborates prior findings that suggested that the media portray contradictory representations of nature that may confuse the public. At the same time that illegal crop production and its consequent chemical eradication destroyed endemic and primary forests in Colombia, the media neglected to illustrate the natural damage or its significance. In all, very little content in either newspaper communicated the concerns of environmental groups and in El Tiempo's case; such concerns were presented as benefiting drug dealers instead of helping the environmental cause. This in turn, may impair public knowledge and reaction about the environmental problem.

description: The Tunka observatory is located close to Lake Baikal in Siberia, Russia. Its main detector, Tunka-133, is an array of photomultipliers measuring Cherenkov light of air showers initiated by cosmic rays in the energy range of approximately $10^{16}-10^{18}\,$eV. In the last years, several extensions have been built at the Tunka site, e.g., a scintillator array named Tunka-Grande, a sophisticated air-Cherenkov-detector prototype named HiSCORE, and the radio extension Tunka-Rex. Tunka-Rex started operation in October 2012 and currently features 44 antennas distributed over an area of about $3\,$km$^2$, which measure the radio emission of the same air showers detected by Tunka-133 and Tunka-Grande. Tunka-Rex is a technological demonstrator that the radio technique can provide an economic extension of existing air-shower arrays. The main scientific goal is the cross-calibration with the air-Cherenkov measurements. By this cross-calibration, the precision for the reconstruction of the energy and mass of the primary cosmic-ray particles can be determined. Finally, Tunka-Rex can be used for cosmic-ray physics at energies close to $1\,$EeV, where the standard Tunka-133 analysis is limited by statistics. In contrast to the air-Cherenkov measurements, radio measurements are not limited to dark, clear nights and can provide an order of magnitude larger exposure.

description: The present paper uses the Tukey test to measure the minimal significative difference (MSD) between crystallographic data predicted by non-linear mathematical models generated from graphics published by Zarinejad (2008) and Potapov (1997) on 5 nominal compositions of Ni50Ti50-XHfX .at% substitutional alloys fused by arc melting and melt spinning processes. Results show that the calculated MSD do not represent a statistically significant difference. Therefore, it is concluded that the independent variable (Hafnium content) does not change the analysed dependent variables (lattice parameters, crystalline structure, volume and monoclinic angle β) for any fusing processes.

description: We present preliminary results of the quasar survey in Large Sky Area Multi- Object Fiber Spectroscopic Telescope (LAMOST) first data release (DR1), which includes pilot survey and the first year regular survey. There are 3921 quasars identified with reliability, among which 1180 are new quasars discovered in the survey. These quasars are at low to median redshifts, with highest z of 4.83. We compile emission line measurements around the Hα, Hβ, Mg II, and C IV regions for the new quasars. The continuum luminosities are inferred from SDSS photo- metric data with model fitting as the spectra in DR1 are non-flux-calibrated. We also compile the virial black hole mass estimates, and flags indicating the selec- tion methods, broad absorption line quasars. The catalog and spectra for these quasars are available online. 28% of the 3921 quasars are selected with optical- infrared colours independently, indicating that the method is quite promising in completeness of quasar survey. LAMOST DR1 and the on-going quasar survey will provide valuable data in the studies of quasars.

description: Preliminary calculations using the Covariant Spectator Theory (CST) employed a scalar linear confining interaction and an additional constant vector potential to compute the mesonic mass spectra. In this work we generalize the confining interaction to include more general structures, in particular a vector and also a pseudoscalar part, as suggested by a recent study. A one-gluon-exchange kernel is also implemented to describe the short-range part of the interaction. We solve the simplest CST approximation to the complete Bethe-Salpeter equation, the one-channel spectator equation, using a numerical technique that eliminates all singularities from the kernel. The parameters of the model are determined through a fit to the experimental pseudoscalar meson spectra, with a good agreement for both quarkonia and heavy-light states.

description: Nuclear star clusters (NSCs) at the dynamical center of galaxies appear to have a complex star formation history. This suggests repeated star formation even in the influence of the strong tidal field from supermassive black holes. In our previous study, we have detected 31 so far unknown early-type star candidates throughout the Galactic NSC (at 0.5 - 3 pc from Sgr A*; Nishiyama and Schoedel 2013). The aim of this study is a confirmation of the spectral type for the candidates. We have carried out NIR spectroscopic observations of the candidates using Subaru/IRCS/AO188/LGS. K-band spectra for 20 out of the 31 candidates were obtained. By determining an equivalent width, EW(CO), of the 12CO absorption feature at 2.294 um, we have derived an effective temperature and a bolometric magnitude for each candidate, and then constructed an HR diagram. No young (~ Myr), massive stars are included in the 20 candidates we observed; however, 13 candidates are most likely intermediate-age giants (50 - 500 Myr). Two other sources have ages of ~1 Gyr, and the remaining five sources are old (> 1 Gyr), late-type giants. Although none of the early-type star candidates from our previous narrow-band imaging observations can be confirmed as a young star, we find that the photometric technique is sensitive to distinguish old, late-type giants from young and intermediate-age populations. The intermediate-age stars could be so far unknown members of a population formed in a starburst ~100 Myr ago. Finding no young (~ a few Myr) stars at R = 0.5 - 3 pc favors the in-situ formation scenario for the presence of the young stars at R < 0.5 pc. Furthermore, the different spatial distributions of the young and the intermediate-age stars imply that the Galactic NSC is an aggregate of stars born in different places and under different physical conditions.

description: A literatura para crianças e jovens pode cumprir, de uma forma lúdica, e/ou até humoristica, a função de educação para a cidadania, transmitindo valores sociais e pessoais ao público infantil e juvenil, e auxiliando a um futuro exercício de plena cidadania. Através da análise das obras literárias A que sabe a Lua? e O Nabo Gigante, de Michael Grejniec e de Alexis Tolstoi, respetivamente, explora-se o diálogo intersemiótico entre os códigos pictórico e verbal, e procura-se trazer à consciência o jogo de sentidos e de símbolos que surgem da articulação e do diálogo entre texto-linguístico e texto-icónico. Conclui-se que estas obras encerram, na sua narrativa, valores de cooperação, solidariedade e entreajuda, e podem constituir uma excelente ferramenta de promoção, no público infantil, de competências de relacionamento com o outro. Ainda mais, por destacarem como heróis, fi guras fi sicamente mais “frágeis”, podem ajudar a criança a valorizar, e a percecionar como herói até a fi gura que, por fora, menos o aparenta ser.

Using linked metadata and quality standards for the documentation of Insee's statistical operations
Creators: name: Cotton, Franck
Publisher: name: Zenodo
Year: 2020

description: Insee publishes on its web site documentation about the statistical operations that it conducts. Behind the scenes, an important effort has been made recently to break down these texts into precise, well-defined and harmonized items. For this, we leveraged a standard used in the European Statistical System for quality reporting: the SIMS model (Single Integrated Metadata Structure). We actually structured and refined the SIMS by translating it to OWL/RDF, adding a few attributes and specifying more rigorous data types (for example, a contact organization would be an organization object instead of just descriptive text). Splitting operation descriptions into the SIMS layout required some initial work from the subject-matter statisticians, but it will greatly simplify future regulatory quality reporting. Also, publishing documentations as RDF will allow to integrate them into a global metadata information system and link them to concepts, codes, organization schemes, the product catalogue, etc. RDF maximizes usability and machine-actionability, so it is possible to offer a variety of dissemination formats: a dedicated API, exports as office documents or SDMX metadata reports ready to send to Eurostat, etc. This will greatly improve and accessibility of our metadata, discoverability of our products and comparability at the national and European levels.

Biomarkers of Lung Epithelial Damage After Inhalation Injury
Creators: name: Vaughan, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Burn and inhalation injury affects almost half a million people in the United States each year and it is one of the most complicated forms of trauma to treat. Further research is needed in order to better understand the precise mechanisms behind both burn and inhalational injury, as well as means by which to more accurately stratify patients by injury severity in order to care for them more effectively. In this study, I examine two potential biomarkers in mice with possible translational relevance that could be of use in quantifying injury severity in hospitalized patients. IL-33 and 8-isoprostane may be indicators of acute and long-term damage, respectively. IL-33 is elevated at twenty-four hours post-injury in mice with inhalation injury, while 8-isoprostane is elevated in mice with combined burn + inhalation injury at two weeks post-injury. These data may begin to provide a method for better patient evaluation and improved outcome.

description: With the Westerbork Synthesis Radio Telescope, we performed HI observations of a sample of known X-ray emitting Gigahertz-peaked-spectrum galaxies with compact-symmetric-object morphology (GPS/CSOs) that lacked an HI absorption detection. We combined radio and X-ray data of the full sample of X-ray emitting GPS/CSOs and found a significant, positive correlation between the column densities of the total and neutral hydrogen ($N_{\rm H}$ and $N_{\rm HI}$, respectively). Using a Bayesian approach, we simultaneously quantified the parameters of the $N_{\rm H} - N_{\rm HI}$ relation and the intrinsic spread of the data set. For a specific subset of our sample, we found $N_{\rm H} \propto N_{\rm HI}^b$, with $b=0.93^{+0.49}_{-0.33}$, and $σ_{int} (N_{\rm H})= 1.27^{+1.30}_{-0.40}$. The $N_{\rm H} - N_{\rm HI}$ correlation suggests a connection between the physical properties of the radio and X-ray absorbing gas.

Principal component analysis of the reionization history from Planck 2015 data

description: The simple assumption of an instantaneous reionization of the Universe may bias estimates of cosmological parameters. In this paper a model-independent principal component method for the reionization history is applied to give constraints on the cosmological parameters from recent Planck 2015 data. We find that the Universe are not completely reionized at redshifts $z \ge 8.5$ at 95% CL. Both the reionization optical depth and the matter fluctuation amplitude are higher than but consistent with those obtained in the standard instantaneous reionization scheme. The high estimated value of the matter fluctuation amplitude strengthens the tension between Planck CMB observations and some astrophysical data, such as cluster counts and weak lensing. The tension can significantly be relieved if the neutrino masses are allowed to vary. Thanks to a high scalar spectral index, the low-scale spontaneously broken SUSY inflationary model can fit the data well, which is marginally disfavored at 95% CL in the Planck analysis.

Holographic polytropic $f(T)$-gravity models

description: The present paper reports a study on the cosmological consequences arising from reconstructing $f(T)$ gravity through new holographic-polytropic dark energy. We assume two approaches, namely a particular form of Hubble parameter $H$ and a solution for $f(T)$. We obtain the deceleration parameter, effective equation of state as well as torsion equation of state parameters from total density and pressure in both cases. It is interesting to mention here that the deceleration and torsion equation of state represent transition from deceleration to acceleration phase. We study the statefinder parameters under both approaches which result that statefinder trajectories are found to attain $Λ$CDM point. The comparison with observational data represents consistent results. Also, we discuss the stability of reconstructed models through squared speed of sound which represents stability in late times.

The Veneziano ghost, glost and gauge copies in QCD

description: In this short note, we come back to the recent proposal put forward by Kharzeev and Levin [PRL 114 (2015) 24, 242001], in which they phenomenologically couple the non-perturbative Veneziano ghost to the perturbative gluon, leading to a modified gluon propagator (the "glost") of the Gribov type, with complex poles. As such, a possible link was made between the QCD topological θ-vacuum (Veneziano ghost) and color confinement (no physically observable gluons). We discuss some subtleties concerning gauge (BRST) invariance of this proposal, related to the choice of Feynman gauge. We furthermore provide an example in the Landau gauge of a similar phenomenological vertex that also describes the necessary Veneziano ghost but does not affect the Landau gauge gluon propagator.

Replication - The effect of BW vs. Color Imagery on Pride and Joy
Creators: name: Bornstein, Oren
name: Moran, Tal
name: Eyal, Tal
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Social and Behavioral Sciences

description: In a preliminary experiment we found that BW (versus color) imagery differentially influenced the intensity of joy and pride. Specifically, we found that images elicited a more intense positive emotional response when presented in color than in BW. Importantly, this effect was less pronounced for pride than for joy images. In this previous study, we realized after collecting the data that some of the joy-eliciting images were more colorful and detailed than the pride-eliciting images. The goal of the present experiment is to overcome this possible confound, by replicating the effect of color on emotion intensity, with joy and pride images that were pretested and found to be not statistically different in their degree of color and details.
A poesia de mãos dadas com a conversa – diferentes olhares expostos pela mão de todos os poetas

description: A escola é a conjugação em todos os tempos e modos do verbo viver; por isso vivemos na escola o tempo e o modo da conversa através e sobre a poesia. Através e sobre o mundo. Porque a poesia, quando levada para a escola e conversada em jeito de partilha, abraça os alunos às palavras. Abraça os alunos à literatura. Deste modo, pretende-se, com o presente artigo, problematizar essa relação dialogal entre a poesia e a conversa, demonstrando que tal relação é imprescindível em qualquer ciclo do ensino básico (e não só) para que os alunos sejam amantes da literatura.

Year: 2013

description: Os contos tradicionais, mais conhecidos por contos de fadas, deram a conhecer ao mundo princesas que ainda hoje povoam o imaginário coletivo da humanidade e que são imediatamente reconhecidas pelos seus atributos de feminilidade: beleza, elegância, doçura, passividade, obediência, recato, discrição, emotividade, vulnerabilidade, bondade, inocência, perícia na execução das tarefas domésticas, entre outros. No entanto, nos últimos anos tem-se verifi cado uma evolução da feminilidade e uma desconstrução de estereótipos. Através de uma análise de quatro contos da literatura infanto-juvenil de duas épocas distintas é feita uma análise dessa evolução.

description: We have discovered an oscillatory magnetoresistance phenomenon in a wide range of superconducting systems, with a periodicity that is essentially independent of temperature, transport current, magnetic field, and even material parameters. The nearly universal period points to a possible fundamental mechanism deeper than superconductivity itself, and may result from intrinsic pair-breaking mechanisms at sub-atomic length scales.

description: Here, we present a novel microscopic technique for measuring wavelength-dependent three-dimensional (3-D) distributions of the refractive indices (RIs) of microscopic samples in the visible wavelengths. Employing 3-D quantitative phase microscopy techniques with a wavelength-swept source, 3-D RI tomograms were obtained in the range of 450 - 700 nm with a spectral resolution of a few nanometers. The capability of the technique was demonstrated by measuring the hyperspectral 3-D RI tomograms of polystyrene beads, human red blood cells, and hepatocytes. The results demonstrate the potential for label-free molecular specific 3-D tomography of biological samples.
What a Wonderful Kiki!: Music and Queerness at Mixtape, a Washington, DC Gay Dance Party
Creators: name: Bowen, Christopher Phillip
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This thesis explores the relationship between queerness and music through two case studies: a monthly Washington, DC gay dance party called Mixtape and a recent song by the band the Scissor Sisters, called Let's Have a Kiki. In so doing I examine and analyze the discursive categories of alternative and mainstream to show on the one hand the ways in which the party and song are constituted and experienced as truly alternative; on the other hand, I show how within this carved-out space new norms and regulatory ideals begin to function, creating mainstreams against and through which behavior and identity are judged and created. I find that these terms partially embody a complex reality of power structures in queer communities, articulated through music.
