Background

Research supports the beneficial role of prosocial behaviors on children's adjustment and successful youth development. Empirical studies point to reciprocal relations between negative parenting and children's maladjustment, but reciprocal relations between positive parenting and children's prosocial behavior are understudied. In this study reciprocal relations between two different dimensions of positive parenting (quality of the mother–child relationship and the use of balanced positive discipline) and children's prosocial behavior were examined in Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States.

We have undertaken an ambitious program to visually classify all galaxies in the five CANDELS fields down to H < 24.5 involving the dedicated efforts of over 65 individual classifiers. Once completed, we expect to have detailed morphological classifications for over 50,000 galaxies spanning 0 < z < 4 over all the fields, with classifications from 3 to 5 independent classifiers for each galaxy. Here, we present our detailed visual classification scheme, which was designed to cover a wide range of CANDELS science goals. This scheme includes the basic Hubble sequence types, but also includes a detailed look at mergers and interactions, the clumpiness of galaxies, k-corrections, and a variety of other structural properties. In this paper, we focus on the first field to be completed—GOODS-S, which has been classified at various depths. The wide area coverage spanning the full field (wide+deep+ERS) includes 7634 galaxies that have been classified by at least three different people. In the deep area of the field, 2534 galaxies have been classified by at least five different people at three different depths. With this paper, we release to the public all of the visual classifications in GOODS-S along with the Perl/Tk GUI that we developed to classify galaxies. We present our initial results here, including an analysis of our internal consistency and comparisons among multiple classifiers as well as a comparison to the Sérsic index. We find that the level of agreement among classifiers is quite good (>70% across the full magnitude range) and depends on both the galaxy magnitude and the galaxy type, with disks showing the highest level of agreement (>50%) and irregulars the lowest (<10%). A comparison of our classifications with the Sérsic index and rest-frame colors shows a clear separation between disk and spheroid populations. Finally, we explore morphological k-corrections between the V-band and H-band observations and find that a small fraction (84 galaxies in total) are classified as being very different between these two bands. These galaxies typically have very clumpy and extended morphology or are very faint in the V-band.

Development Of Proton Conduction Membranes In Application Of Vanadium Flow Battery, Le-Tu Qingge, Wei-Nan Guo, Ping Liu, Bao-Guo Wang

Journal of Electrochemistry

The polymeric hydrophilic/hydrophobic interactions into membrane formation were introduced. A general and straightforward strategy for preparing membranes with nanometer-scale pores was suggested by utilization of hydrophilic/hydrophobic interactions to generate phase separation and removal of polyion aggregates through water immersion. Poly(vinylidene fluoride) (PVDF) and sodium allyl sulfonate (SAS) serve as the membrane material and pore-generator, respectively, resulting in chemically stable and oxidation-resistant membranes with various potential applications. Following the same procedure invented to produce the laboratory-scale membranes, the scale-up process to manufacture large-area membranes was completed. The obtained membrane exhibited the conductivity of 3.5×10^-2 S•cm^-1, thickness of 100 …

Energy Dissipation And Constitutive Modeling For A Mechanistic Description Of Pad Scratching In Chemical-Mechanical Planarization, David Ponte, D.M.L. Meyer

Mechanical, Industrial & Systems Engineering Faculty Publications

A thermomechanical model to describe the mechanisms of polishing pad scratching in chemical–mechanical planarization (CMP) has been formulated and investigated. CMP is a necessary process in integrated circuit (IC) fabrication to planarize wafers with nanoscale features after patterned layer deposition. Polishing pad asperities can produce microscale scratches on the wafer surface during CMP, reducing IC manufacturing yields. The constructed thermomechanical model accounts for stresses of the pad and wafer contact and also provides the means to track input energy dissipation during CMP. Tracking energy dissipation offers information about processes that may influence scratch production. This knowledge ultimately produces a greater …

Reinforcing Endothelial Junctions Prevents Microvessel Permeability Increase And Tumor Cell Adhesion In Microvessels In Vivo, Bingmei M. Fu, Jinlin Yang, Bin Cai, Jie Fan, Lin Zhang, Min Zeng

Publications and Research

Tumor cell adhesion to the microvessel wall is a critical step during tumor metastasis. Vascular endothelial growth factor (VEGF), a secretion of tumor cells, can increase microvessel permeability and tumor cell adhesion in the microvessel. To test the hypothesis that inhibiting permeability increase can reduce tumor cell adhesion, we used in vivo fluorescence microscopy to measure both microvessel permeability and adhesion rates of human mammary carcinoma MDA-MB-231 cells in post-capillary venules of rat mesentery under the treatment of VEGF and a cAMP analog, 8-bromo-cAMP, which can decrease microvessel permeability. By immunostaining adherens junction proteins between endothelial cells forming the microvessel …

Characterization Of The Separator With Thermal-Shutdown Layer For Use In Lithium Batteries, Li Bai, Yong-Jian Huai, Xin-Ping Ai, Hai Jia

Journal of Electrochemistry

In this paper, the lithium ion battery coated with the thermal-shutdown functional layer has been introduced. The shutdown temperature of the separator could be decreased by using the melting point of thermal-shutdown functional layer. When the internal battery environment reached a critical temperature, the functional layer melted and coated the anode/separator with a non-conductive barrier, halting Li-ion transport and shutting down the cell permanently. The results showed that the functional layer did not affect the resistance, rate performance and cycle life. It was found the functional layer can significantly improve the safety of the battery when misused.

Principal Leadership Practices In High Poverty K-5 Model Schools In Oregon, Janice Marie Adams

Dissertations and Theses

Children living in poverty in the United States face some of life's greatest challenges, including achieving academic success in school. Evidence is also emerging of a growing income disparity in America that affects families, communities and local labor markets in ways that can undermine the effectiveness of schools serving disadvantaged populations (Duncan & Murnane, 2011). Evidence exists, however, that high academic performance is within the reach of all children in high poverty schools, and that principal leadership is a contributing factor.

This study examined principal leadership practices in three high poverty K-5 elementary schools in Oregon identified as Model schools …
