TL;DR: The development of child and adolescent self-concept was examined as a function of the self- Concept domain, social/developmental/educational transitions, and gender.
Abstract: The development of child and adolescent self-concept was examined as a function of the self-concept domain, social/developmental/educational transitions, and gender. In two overlapping age cohorts of public school students (Ns = 936 and 984), five dimensions of self-concept were evaluated every 6 months in a manner that spanned grades 3 through 11 (representing the elementary, middle, and high school years). Domains of self-concept included academic competence, physical appearance, behavioral conduct, social acceptance, and sports competence. Structural equation modeling addressed questions about the stability of individual differences over time. Multilevel modeling addressed questions about mean-level changes in self-concept over time. Significant effects emerged with regard to gender, age, dimension of self-concept, and educational transition.

TL;DR: In this paper, the thermal conductivities of β-Ga2O3 single crystals along four different crystal directions were measured in the temperature range of 80 −495 K using the time domain thermoreflectance method.
Abstract: The thermal conductivities of β-Ga2O3 single crystals along four different crystal directions were measured in the temperature range of 80–495 K using the time domain thermoreflectance method. A large anisotropy was found. At room temperature, the [010] direction has the highest thermal conductivity of 27.0 ± 2.0 W/mK, while that along the [100] direction has the lowest value of 10.9 ± 1.0 W/mK. At high temperatures, the thermal conductivity follows a ∼1/T relationship characteristic of Umklapp phonon scattering, indicating phonon-dominated heat transport in the β-Ga2O3 crystal. The measured experimental thermal conductivity is supported by first-principles calculations, which suggest that the anisotropy in thermal conductivity is due to the differences of the speed of sound along different crystal directions.

TL;DR: This work considers three different geometric centrality measures, excentricity, status, and centroid value, that were originally used in the context of resource placement problems and shows that these quantities lead to useful descriptions of the centers of biological networks.

TL;DR: This article examined why some democracies and semi-democracies develop relatively stable party systems, while others continue to be roiled by high levels of electoral volatility, and they found that competitive regimes inaugurated in earlier periods have much lower electoral volatility than those inaugurated more recently, even controlling for a variety of other factors that have been hypothesized to affect electoral volatility.
Abstract: This article examines why some democracies and semi-democracies develop relatively stable party systems, while others continue to be roiled by high levels of electoral volatility It is the first broadly cross-regional analysis of electoral volatility, and it is based on the most extensive data assembled on electoral volatility Our most original finding is that competitive regimes inaugurated in earlier periods have much lower electoral volatility than regimes inaugurated more recently, even controlling for a variety of other factors that have been hypothesized to affect electoral volatility Parties had very different functions according to when democracy was inaugurated, and these congenital differences had longterm effects on the stabilization of party competition What matters for the stabilization of party competition is when democracy was born, not how old it is Our results support social science approaches that emphasize historical sequences and path dependence

TL;DR: In this paper, the authors present multizone models of Type I X-ray bursts that use an adaptive nuclear reaction network of unprecedented size, up to 1300 isotopes, for energy generation and include the most recent measurements and estimates of critical nuclear physics.
Abstract: Multizone models of Type I X-ray bursts are presented that use an adaptive nuclear reaction network of unprecedented size, up to 1300 isotopes, for energy generation and include the most recent measurements and estimates of critical nuclear physics. Convection and radiation transport are included in calculations that carefully follow the changing composition in the accreted layer, both during the bursts themselves and in their ashes. Sequences of bursts, up to 15 in one case, are followed for two choices of accretion rate and metallicity, up to the point at which a limit cycle equilibrium is established. For (M)over dot=1.75x10(-9) M-circle dot yr(-1) (and (M)over dot=3.5x10(-10) M-circle dot yr(-1), for low metallicity), combined hydrogen-helium flashes occur. These bursts have light curves with slow rise times (seconds) and long tails. The rise times, shapes, and tails of these light curves are sensitive to the efficiency of nuclear burning at various waiting points along the rp-process path, and these sensitivities are explored. Each displays ``compositional inertia`` in that its properties are sensitive to the fact that accretion occurs onto the ashes of previous bursts that contain leftover hydrogen, helium, and CNO nuclei. This acts to reduce the sensitivity of burst properties to metallicity. Only the first anomalous burst in one model produces nuclei as heavy as A=100. For the present choice of nuclear physics and accretion rates, other bursts and models make chiefly nuclei with Aapproximate to64. The amount of carbon remaining after hydrogen-helium bursts is typically less than or similar to1 and decreases further as the ashes are periodically heated by subsequent bursts. For (M)over dot=3.5x10(-10) M-circle dot yr(-1) and solar metallicity, bursts are ignited in a hydrogen-free helium layer. At the base of this layer, up to 90 to carbon prior to the unstable ignition of the helium shell. These helium-ignited bursts have (1) briefer, brighter light curves with shorter tails, (2) very rapid rise times (>0.1 s), and (3) ashes lighter than the iron group.
