description: Nei Paesi d’immigrazione, com’è l’Italia dalla metà degli anni ’80, la presenza nelle scuole di alunni con cittadinanza straniera è un fenomeno a intensità crescente, la scuola essendo (soprattutto per le seconde generazioni degli immigrati) un grande veicolo d’integrazione. Il lavoro discute le peculiarità del caso italiano dall’inizio degli anni ’80 (meno dell’1‰) alla metà degli anni ’10 del nuovo millennio (quasi il 6%, con punte regionali prossime al 10%) evidenziando le problematiche che derivano dalla multietnicità delle provenienze, dalla non omogenea diffusione territoriale della presenza d’immigrati-scolarizzati e dalla (presumibile) non reversibilità delle tendenze in atto.

description: We present a new deep determination of the spectroscopic LF within the virial radius of the nearby and massive Abell\,85 (A85) cluster down to the dwarf regime (M* + 6) using VLT/VIMOS spectra for $\sim 2000$ galaxies with m$_r \leq 21$ mag and $\langle μ_{e,r} \rangle \leq 24$ mag arcsec$^{-2}$. The resulting LF from 438 cluster members is best modelled by a double Schechter function due to the presence of a statistically significant upturn at the faint-end. The amplitude of this upturn ($α_{f} = -1.58^{+0.19}_{-0.15}$), however, is much smaller than that of the SDSS composite photometric cluster LF by Popesso et al. 2006, $α_{f} \sim$ -2. The faint-end slope of the LF in A85 is consistent, within the uncertainties, with that of the field. The red galaxy population dominates the LF at low luminosities, and is the main responsible for the upturn. The fact that the slopes of the spectroscopic LFs in the field and in a cluster as massive as A85 are similar suggests that the cluster environment does not play a major role in determining the abundance of low-mass galaxies.

description: We discuss our results on QCD with a number of fundamental fermions ranging from zero to sixteen. These theories exhibit a wide array of fascinating phenomena which have been under close scrutiny, especially in recent years, first and foremost is the approach to conformality. To keep this review focused, we have chosen scale generation, or lack thereof as a guiding theme, however the discussion will be set in the general framework of the analysis of the phases and phase transitions of strong interactions at zero and nonzero temperature.

description: Histone lysine methyltransferases have crucial roles in a number of biological processes and human diseases by controlling gene expression and chromatin state. Within this family, the lysine methyltransferase G9a has emerged as critical player in several pathologic states, particularly because of its important role in the silencing of tumor suppressor genes and in the regulation of other chromatin events. The low number of G9a chemical probes suitable for cell-based and animal studies, as well as the limited chemical diversity demand for the development of new modulators. In this thesis, two different approaches aimed at the identification of novel chemotypes for the modulation of G9a are presented. On one hand, from a medicinal chemistry prospective, we considered the modification of the central core of the potent and selective inhibitor UNC0638, resulting in a 1,4-benzodiazepine derivative EML741. To validate the approach, we designed and synthesized a small set of ring-expanded derivatives and tested their activity in vitro. Peptide-based biochemical assays (AlphaLISA) validated our design, as compound EML741 preserves the activity of the parent compound. In fact, EML741 is a G9a competitive inhibitor with respect to substrate endowed with potent activity and selectivity. In addition, EML741 showed favorable physico-chemical properties as it is quite soluble and chemical stable in aqueous media, and exhibited a membrane permeability profile (PAMPA and PAMPA-BBB) better than the parent compound UNC0638...

Quasiparticle band structures and thermoelectric transport properties of p-type SnSe

Publisher: name: arXiv
Year: 2014
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: We used density functional and many-body perturbation theory to calculate the quasiparticle band structures and electronic transport parameters of p-type SnSe both for the low-temperature Pnma and high-temperature Cmcm phases. The Pnma phase has an indirect band gap of 0.829 eV while the Cmcm has a direct band gap of 0.464 eV. Both phases exhibit multiple local band extrema within an energy range comparable to the thermal energy of carriers from the global extrema. We calculated the electronic transport coefficients for single-crystal and polycrystalline materials to understand previous experimental measurements. We also discuss the dependence of the transport coefficients on doping concentration and temperature to identify doping conditions for optimal thermoelectric performance.

description: We investigate solid-on-solid models that belong to the Kardar-Parisi-Zhang (KPZ) universality class on substrates that expand laterally at a constant rate by duplication of columns. Despite the null global curvature, we show that all investigated models have asymptotic height distributions and spatial covariances in agreement with those expected for the KPZ subclass for curved surfaces. In $1+1$ dimensions, the height distribution and covariance are given by the GUE Tracy-Widom distribution and the Airy$_2$ process, instead of the GOE and Airy$_1$ foreseen for flat interfaces. These results imply that, when the KPZ class splits into the curved and flat subclasses, as conventionally considered, the expanding substrate may play a role equivalent to, or perhaps more important than the global curvature. Moreover, the translational invariance of the interfaces evolving on growing domains allowed us to accurately determine, in $2+1$ dimensions, the analogue of the GUE Tracy-Widom distribution for height distribution and that of the Airy$_2$ process for spatial covariance. Temporal covariance is also calculated and shown to be universal in each dimension and in each of the two subclasses. A logarithmic correction associated to the duplication of column is observed and theoretically elucidated. Finally, crossover between regimes with fixed-size and enlarging substrates is also investigated.

description: We present Nustar 3-40 keV observations of the optically selected Type 2 quasar (QSO2) SDSS J1034+6001 or Mrk 34. The high-quality hard X-ray spectrum and archival XMM-Newton data can be fitted self-consistently with a reflection-dominated continuum and strong Fe Kalpha fluorescence line with equivalent-width >1 keV. Prior X-ray spectral fitting below 10 keV showed the source to be consistent with being obscured by Compton-thin column densities of gas along the line-of-sight, despite evidence for much higher columns from multiwavelength data. NuSTAR now enables a direct measurement of this column, and shows that Nh lies in the Compton-thick (CT) regime. The new data also show a high intrinsic 2-10 keV luminosity of L_{2-10}~10^{44} erg/s, in contrast to previous low-energy X-ray measurements for which L_{2-10}

title: Work Across the Generations: Communication Narratives of Stay-at-Home Fathers in Early and Middle Adulthood
Creators: name: Jones, Alice L.
Publisher: name: Old Dominion University Libraries
Year: 2015

description: The notion of work whether it is done inside or outside the home represents a complex and shifting pattern of social relationships, gender role identities, and ideologies. For an increasing numbers of men, who represent the population of fathers labeled as "stay-at-Home Dad" [SAHD] or "stay-at-home father" [SAHF], these changes have created special challenges, controversies, and raised questions about cultural expectations concerning the transition from that of a stigmatized role to that of a "new, involved father" (Eranta & Moisander, 2011; Rochlen, 2008). Increased participation by men in roles that challenge traditional and long standing gender role norms and expectations also challenges how men and women behave, and how popular culture speaks to our understanding of stay-at-home fathers and the communication challenges they face. The purpose of this qualitative study is to better understand the communicative discourse of contemporary stay-at-home fathers (SAHF) and the resulting narratives in relation to their roles as men, fathers, and workers.

Using a Grounded Theory Approach (Glaser & Strauss, 1967), narratives of stayat-home fathers were gathered through personal interviews and evaluated using constant comparative methodology involving multiple readings of the transcribed interviews. This process was used to identify common themes and categories in order to better understand and identify how men in various lifespan stages talk about and view their roles as stay-at-home fathers. Specifically, how do ideas of work, its meanings and values translate into their conversations and their families' lived experiences as well as how do they perceive concepts of gender, work and family that frame the communicative discourse of stay-at-home fathers?

Contrary to previous research that viewed stay-at-home fathers as a homogeneous group, results of this study indicate there are in fact distinct differences. Specifically this study's results support a new grounded, classification scheme that arranges SAHFs along a continuum of the degree of acceptance of the SAHF role. That is, the data suggests at least four types of stay-at-home fathers that vary in the extent to which they embrace the role from high to low level of role embracing: Revolutionary Stay-at Home Father, Reformer Stay-at Home Father, Reluctant Stay-at-Home Father, and Resentful Stay-at-Home Father as well as common narratives used by the fathers in the stay-at-home role to help negotiate the balance between their role as stay-at-home father and issues of gender, identity, work, and family. Finally, implications of this study for future research seeking to examine the impact of stay-at-home fathers on resulting communication patterns within families, particularly in regard to spouses/partners and children are discussed.

description: A recent XMM-Newton observation (Zhekov 2014) has revealed diffuse X-ray emission inside the nebula NGC 2359 around the Wolf-Rayet star WR 7. Taking advantage of an improved point-source rejection and background subtraction, and a detailed comparison of optical and X-ray morphology, we have reanalyzed these X-ray observations. Our analysis reveals diffuse X-ray emission from a blowout and the presence of emission at energies from 1.0 to 2.0 keV. The X-ray emission from NGC 2359 can be described by an optically-thin plasma emission model, but contrary to previous analysis, we find that the chemical abundances of this plasma are similar to those of the optical nebula, with no magnesium enhancement, and that two components at temperatures T_1=2x10^6 K and T_2=5.7x10^7 K are required. The estimated X-ray luminosity in the 0.3 - 2.0 keV energy range is L_X=2x10^33 erg s^-1. The averaged rms electron density of the X-ray-emitting gas (n_e \lesssim 0.6 cm^-3) reinforces the idea of mixing of material from the outer nebula into the hot bubble.

description: The Kepler mission has revolutionized our understanding of exoplanets, but some of the planet candidates identified by Kepler may actually be astrophysical false positives or planets whose transit depths are diluted by the presence of another star. Adaptive optics images made with ARIES at the MMT of 87 Kepler Objects of Interest place limits on the presence of fainter stars in or near the Kepler aperture. We detected visual companions within 1" for five stars, between 1" and 2" for seven stars, and between 2" and 4" for 15 stars. For those systems, we estimate the brightness of companion stars in the Kepler bandpass and provide approximate corrections to the radii of associated planet candidates due to the extra light in the aperture. For all stars observed, we report detection limits on the presence of nearby stars. ARIES is typically sensitive to stars approximately 5.3 Ks magnitudes fainter than the target star within 1" and approximately 5.7 Ks magnitudes fainter within 2", but can detect stars as faint as delta Ks = 7.5 under ideal conditions.

On Renyi entropy for free conformal fields: holographic and q-analog recipes

description: We describe a holographic approach to explicitly compute the universal logarithmic contributions to entanglement and Renyi entropies for free conformal scalar and spinor fields on even-dimensional spheres. This holographic derivation proceeds in two steps: first, following Casini and Huerta, a conformal map to thermal entropy in a hyperbolic geometry; then, identification of the hyperbolic geometry with the conformal boundary of a bulk hyperbolic space and use of an AdS/CFT holographic formula to compute the resulting functional determinant. We explicitly verify the connection with the type-A trace anomaly for the entanglement entropy, whereas the Renyi entropy is computed with aid of the Sommerfeld formula in order to deal with a conical defect. As a by-product, we show that the log-coefficient of the Renyi entropy for round spheres can be efficiently obtained as the q-analog of a procedure similar to the one found by Cappelli and D'Appollonio that rendered the type-A trace anomaly.

description: The crack initiation and short crack propagation in a martensitic spring steel were investigated by means of in-situ fatigue testing. Shot peened samples as well as untreated samples were exposed to uniaxial alternating stress to analyze the impact of compressive residual stresses. The early fatigue damage started in both sample conditions with the formation of slip bands, which subsequently served as crack initiation sites. Most of the slip bands and, correspondingly, most of the short fatigue cracks initiated at or close to prior austenite grain boundaries. The observed crack density of the emerging network of short cracks increased with the number of cycles and with increasing applied stress amplitudes. Furthermore, the prior austenite grain boundaries acted as obstacles to short crack propagation in both sample conditions. Compressive residual stresses enhanced the fatigue strength, and it is assumed that this beneficial effect was due to a delayed transition from short crack propagation to long crack propagation and a shift of the crack initiation site from the sample surface to the sample interior.

description: „The future mobility will be electrified“– a phrase which has a significant impact on last year’s development. Indeed, the steps to a sustainable society requires not only the application of novel high power battery technologies, furthermore will combustion engines play an important role to achieve this sophisticated target. Due to its high complexity, an infrastructure based on an electric energy only supply is in many locations not applicable. Thus, synthetic fuel solutions have to be applied as an alternative sustainable energy source. As a consequence, a huge variety of fuels may be brought into local markets with their own impact on the combustion engine. The mandatory change of the combustion engine requires more than friction reduction, but also novel combustion approaches as well as the application of novel fuels. Herein, the fuel injection system acts as interface between the fuel and the mechanical engine operation. Nevertheless, this system suffers typically in its operation by its low total efficiency of ~15%. Therefore, optimization has shown that CO2 emission benefits of up to 5 g/km in cycles are possible.
description: „Die Mobilität der Zukunft fährt elektrisch“ – ein Satz, der die vergangenen Jahre geprägt hat. Der Schritt zu einer regenerativen Verkehrswirtschaft erfordert, aber global nicht nur den Einsatz von Batterien, sondern wird auch mittelfristig den Verbrennungsmotor benötigen. Die Komplexität einer rein elektrisch basierten Infrastruktur ist an vielen Orten nicht realisierbar, daher müssen synthetische Kraftstoffe als Alternative angewendet werden. Daraus resultiert jedoch ein Flickenteppich verschiedener Kraftstoffe, die unterschiedliche Einflüsse auf den Motor haben. Der notwendige Wandel des Verbrennungsmotors als mittelfristige Antriebslösung bedarf nicht nur „klassischer“ Optimierungen - wie Reibungsreduktion - sondern neuer Brennverfahren oder die Verwendung neuer künstlicher Kraftstoffe. Das Kraftstoffsystem fungiert hierbei als Bindeglied zwischen einem neuen Kraftstoff und dem Motor. Optimierungen in diesem System bewirken, aufgrund des niedrigen Gesamtwirkungsgrades von im Mittel 15%, signifikante CO2 Emissionsverringerungen von bis zu 5 g/km im NEDC Zyklus.

description: Observations over the past 20 years have revealed a strong relationship between the properties of the supermassive black hole (SMBH) lying at the center of a galaxy and the host galaxy itself. The magnitude of the spin of the black hole will play a key role in determining the nature of this relationship. To date, direct estimates of black hole spin have been restricted to the local Universe. Herein, we present the results of an analysis of $\sim$ 0.5 Ms of archival Chandra observations of the gravitationally lensed quasar Q 2237+305 (aka the "Einstein-cross"), lying at a redshift of z = 1.695. The boost in flux provided by the gravitational lens allows constraints to be placed on the spin of a black hole at such high redshift for the first time. Utilizing state of the art relativistic disk reflection models, the black hole is found to have a spin of $a_* = 0.74^{+0.06}_{-0.03}$ at the 90% confidence level. Placing a lower limit on the spin, we find $a_* \geq 0.65$ (4$σ$). The high value of the spin for the $\rm \sim 10^9~M_{\odot}$ black hole in Q 2237+305 lends further support to the coherent accretion scenario for black hole growth. This is the most distant black hole for which the spin has been directly constrained to date.

We perform a phenomenological analysis of this model, with a focus on the spin-1 top partner, which we dub the "swan". We find that precision electroweak fits, together with direct searches for $Z^\prime$ bosons at the LHC, place a lower bound of at least about 4.5 TeV on the swan mass. An even stronger bound, 10 TeV or above, applies in most of the parameter space, mainly due to the fact that the swan is typically predicted to be significantly heavier than the $Z^\prime$. We find that the 125 GeV Higgs can be easily accommodated in this model with non-decoupling D-terms. In spite of the strong lower bound on the swan mass, we find that corrections to Higgs couplings to photons and gluons induced by swan loops are potentially observable at future Higgs factories. We also briefly discuss the prospects for discovering a swan at the proposed 100 TeV $pp$ collider.

description: The set of subsystems of a finite quantum system (with variables in Z(n)) together with logical connectives, is a distributive lattice. With regard to this lattice, the (where P(m) is the projector to) obeys a supermodularity inequality, and it is interpreted as a lower probability in the sense of the Dempster-Shafer theory, and not as a Kolmogorov probability. It is shown that the basic concepts of the Dempster-Shafer theory (lower and upper probabilities and the Dempster multivaluedness) are pertinent to the quantum formalism of finite systems.

title: Zombies as a Generational Metaphor: Connections Between George A. Romero, Zombies and Fandom -- A Critical Study
Creators: name: Torres, Alfredo
Publisher: name: Old Dominion University Libraries
Year: 2013

description: Since the creation of the modern day zombie by George A. Romero in his directorial debut with the genre altering film Night of the Living Dead in 1968, zombie have been associated with becoming a metaphoric representation of social and cultural issues surrounding the times these films were released, with Romero's films being at the forefront of this phenomenon. A review of Romero's career including his influences was examined as well as the film history of the zombie subgenre, the connections it has to its fans and how the fans influenced the development of the genre. A survey was connected with 64 participants to exam two hypotheses. Hypotheses one seeks to exam the connection between age and fandom to the zombie genre. The second hypothesis seeks to exam the connection between level of fandom and metaphoric representation of the zombie as social or cultural issues. The results showing a correlation between the variables of age, fandom and metaphoric representation of zombies provides partial support for both hypotheses. The results are discussed with future research pertaining to levels of participation and seeking a connection between George A. Romero and zombies based on age are recommended.

A First Site of Galaxy Cluster Formation: Complete Spectroscopy of a Protocluster at $z=6.01$

description: We performed a systematic spectroscopic observation of a protocluster at $z=6.01$ in the Subaru Deep Field. We took spectroscopy for all 53 $i'$-dropout galaxies down to $z'=27.09\,\mathrm{mag}$ in/around the protocluster region. From these observations, we confirmed that 28 galaxies are at $z\sim6$, of which ten are clustered in a narrow redshift range of $Δz<0.06$. To trace the evolution of this primordial structure, we applied the same $i'$-dropout selection and the same overdensity measurements used in the observations to a semi-analytic model built upon the Millennium Simulation. We obtain a relation between the significance of overdensities observed at $z\sim6$ and the predicted dark matter halo mass at $z=0$. This protocluster with $6σ$ overdensity is expected to grow into a galaxy cluster with a mass of $\sim5\times10^{14}\,\mathrm{M_\odot}$ at $z=0$. Ten galaxies within $10\,\mathrm{comoving\>Mpc}$ of the overdense region can, with more than an 80% probability, merge into a single dark matter halo by $z=0$. No significant differences appeared in UV and Ly$α$ luminosities between the protocluster and field galaxies, suggesting that this protocluster is still in the early phase of cluster formation before the onset of any obvious environmental effects. However, further observations are required to study other properties, such as stellar mass, dust, and age. We do find that galaxies tend to be in close pairs in this protocluster. These pair-like subgroups will coalesce into a single halo and grow into a more massive structure. We may witness an onset of cluster formation at $z\sim6$ toward a cluster as seen in local universe.

description: We study the solutions of string fluid equations under assumption of a local equilibrium which was previously obtained in the context of the kinetic theory. We show that the fluid can be foliated into non-interacting submanifolds whose equations of motion are exactly that of the wiggly strings considered previously by Vilenkin and Carter. In a special case of negligible statistical variance in either the left or the right-moving directions of microscopic strings, the submanifolds are described by the action of chiral strings proposed by Witten. When both variances vanish the submanifolds are described by the Nambu-Goto action and the string fluid reduces to the string dust introduced by Stachel.
