How Learning and Living Resilience amidst Experiences of Difference, Stigma, Marginalization, and Loss Contributed to my Identity as a Social Justice Educator: A Scholar Personal Narrative

This qualitative study, written as a Scholarly Personal Narrative (SPN), explores how experiences of difference, stigma, marginalization, and loss resulted in an evolving social justice identity further shaped by resilience and hegemony. Living in a family defined by mental illness and poverty, the narrative arc of the SPN explores how this scholar learned and lived resilience, ultimately resulting in a passion for social justice. The discovery of hegemonic norms at play ultimately opened new understandings, which evoked healing, joy, and a desire to build classrooms where students can claim the power of their own stories. This study recommends the need to extend social justice beyond the walls of academia as a way to cultivate environments that honor the lived experiences of all people while also challenging hegemonic norms that oppress and marginalize. It further recommends using other theoretical lenses beyond the risk resilience binary as a way to disrupt the overcoming narrative while challenging deficit thinking so prevalent in how we frame our lives and make meaning of our experiences

Probing the parton densities of virtual photons with the reaction gamma^*gamma->jets at LEP

We present a next-to-leading order calculation of jet production in gamma^*gamma collisions from e+e- scattering in a region where the virtuality Q^2 of the probing virtual photon is small compared to the transverse jet energy. The calculation is based on the phase-space slicing method. The initial state singularity of the virtual photon is factorized into the structure function of the virtual photon, using the MS-bar factorization scheme for virtual photons. Numerical results are presented for LEP2 conditions. The perturbative stability of the pure direct virtual photon approach is compared to that of including resolved virtual photons in different regions of Q^2. We make predictions for cross sections which suggest that different parametrizations of virtual photon parton densities should be distinguishable by measurements of jet cross sections at LEP.Comment: 19 pages, 8 eps figue

My colleagues (do not) think the same: Middle managers’ shared and separate realities in strategy implementation

How does middle managers’ sensemaking of other middle managers’ attitudes to a new strategy affect strategy implementation? We explore this question using a qualitative-abductive approach. Our investigation of the implementation of a top-down strategy in the plant of a multinational German engineering company revealed that middle managers experiencing ambiguity make sense of other middle managers’ attitudes to the strategy in social interactions. Based on their understanding of their colleagues’ attitudes, middle managers construct shared and separate realities about the strategy to be implemented. While shared realities are subjectively experienced commonalities, separate realities are subjectively experienced differences from others’ attitudes to the strategy. In our case, middle managers’ shared realities were associated with inaction on strategy implementation, whereas middle managers’ separate realities were related to initial actions to implement the strategy. Our findings suggest that middle managers’ sensemaking of other middle managers’ attitudes to a new strategy can shape their strategy implementation behavior

Disordered RNA chaperones can enhance nucleic acid folding via local charge screening

This work is licensed under a Creative Commons Attribution 4.0 International License.RNA chaperones are proteins that aid in the folding of nucleic acids, but remarkably, many of these proteins are intrinsically disordered. How can these proteins function without a well-defined three-dimensional structure? Here, we address this question by studying the hepatitis C virus core protein, a chaperone that promotes viral genome dimerization. Using single-molecule fluorescence spectroscopy, we find that this positively charged disordered protein facilitates the formation of compact nucleic acid conformations by acting as a flexible macromolecular counterion that locally screens repulsive electrostatic interactions with an efficiency equivalent to molar salt concentrations. The resulting compaction can bias unfolded nucleic acids towards folding, resulting in faster folding kinetics. This potentially widespread mechanism is supported by molecular simulations that rationalize the experimental findings by describing the chaperone as an unstructured polyelectrolyte.Swiss National Science FoundationEuropean Molecular Biology OrganizationIntramural Research Program of the NIDDK at the National Institutes of Healt

SALINAS - An implicit finite element structural dynamics code developed for massively parallel platforms

As computational needs for structural finite element analysis increase, a robust implicit structural dynamics code is needed which can handle millions of degrees of freedom in the model and produce results with quick turn around time. A parallel code is needed to avoid limitations of serial platforms. Salinas is an implicit structural dynamics code specifically designed for massively parallel platforms. It computes the structural response of very large complex structures and provides solutions faster than any existing serial machine. This paper gives a current status of Salinas and uses demonstration problems to show Salinas' performance

Race and Gender Differences of Body Physique and Self-Esteem in High School Students

This study investigated race and gender differences of body physique and self-esteem in high school students (N = 754, mean age = 16.5 + 1.2 yr) attending public schools. Participants completed a five part body physique questionnaire where responses were based on a set of nine figure silhouette drawings and a five part self esteem questionniare. African American females reported significantly larger body physique preferences when compared to their Caucasian counterparts (p0.05). African American’s (males and females) scored significantly higher on the self-esteem assessment than their Caucasian counterparts. These findings suggest that there might be important race and gender differences on various aspects of body physique and self-esteem in high school students

Исследование закономерностей развития структурно-химической неоднородности в разнородном сварном соединении трубопроводного переходника

Данная работа посвящена исследованию структурно-химической неоднородности (СХН) трубопроводного переходника из разнородных сталей, выполненного аргонодуговой сваркой (АрДС). При помощи оптического микроскопа получены фотографии СХН и ее размеры. СХН выражается в появлении прослоек (карбидной и ферритной) с разным химическим составом. Приведены графики роста ширин прослоек от времени выдержки и температуры.This paper is devoted to the comparison of the structural and chemical inhomogeneity (SCI) of adapters made of dissimilar steels, made by tungsten insert gas (TIG). By means of optical microscope, photographs of the SCI and its dimensions were obtained. SCI is expressed in the appearance of interlayers (carbide and ferritic) with different chemical composition. Graphs of the growth of the widths of the interlayers from the time of exposure and temperature are given
