Children’s Engineering Identity Development Within an At-Home Engineering Program During COVID-19

The culture of engineering and the culture of formal learning environments often make it difficult for individuals to develop an engineering identity. Conversely, recent research points to the home environment as an alternative setting to support disciplinespecific identity development of children, while less is known regarding the identity development of children as engineers. Therefore, the purpose of this study was to explore the development of children’s engineering identity through the co-creation of engineering concepts and engagement with engineering design thinking and processes with family members in home environments during the COVID-19 pandemic. We conducted interviews with nine families—nine parents and 13 children in Grades 3–6. Analysis of the interviews highlighted how situational interest, recognition, self-efficacy, and doing engineering shaped and informed children’s developing identity. For example, child participants expressed heightened situational interest in the engineering design process and various genres of engineering, with some self-identifying as a particular type of engineer based on their interests. Some expressed greater interest in utilizing engineering practices and processes in the future, either as a career or as a hobby. As another finding, child participants discursively enacted and behaved as engineers through their experiences with collaboration, failure, and perseverance. Concurrently, parent participants articulated their child(ren)’s developing engineering identity, particularly in how their children conducted new processes and modeled the thinking and perseverance of engineers. Parents also noted the development of an inquisitive mindset regarding materials and objects in their home and community environments. We argue that the significance of this study lies in the potential to develop children’s engineering identity in home environments beyond the pandemic, as well as inform children’s identity trajectory as engineers as they continue to accumulate traces of an engineering identity over time and space

Families Engineering Together in Communities and At Home: Facilitation Guide

In this publication, we present a program that serves as a bridge between families and learning environments of all kinds, and provides a pathway for engineering design to be incorporated into the everyday lives of families and kids. Supporting families in their home environment, the program offers a fun and approachable introduction to thinking about engineering and bringing these concepts to life. Conversation and engagement between children and caregivers is so important during elementary school years - this program encourages families to think about, discuss, and experience engineering in a fun and accessible way in their home and community environments. This guide is written to support other stakeholders in implementing a similar program for families to engage as engineers together

HDAC1 interacts with the p50 NF-κB subunit via its nuclear localization sequence to constrain inflammatory gene expression

The NF-κB p50 subunit is an important regulator of inflammation, with recent experimental evidence to support it also having a tumor suppressor role. Classically, p50 functions in heterodimeric form with the RelA (p65) NF-κB subunit to activate inflammatory genes. However, p50 also forms homodimers which actively repress NF-κB-dependent inflammatory gene expression and exert an important brake on the inflammatory process. This repressive activity of p50:p50 is thought to be in part mediated by an interaction with the epigenetic repressor protein Histone Deacetylase 1 (HDAC1). However, neither the interaction of p50 with HDAC1 nor the requirement of HDAC1 for the repressive activities of p50 has been well defined. Here we employed in silico prediction with in vitro assays to map sites of interaction of HDAC1 on the p50 protein. Directed mutagenesis of one such region resulted in almost complete loss of HDAC1 binding to p50. Transfected mutant p50 protein lacking the putative HDAC1 docking motif resulted in enhanced cytokine and chemokine expression when compared with cells expressing a transfected wild type p50. In addition, expression of this mutant p50 was associated with enhanced chemoattraction of neutrophils and acetylation of known inflammatory genes demonstrating the likely importance of the p50:HDAC1 interaction for controlling inflammation. These new insights provide an advance on current knowledge of the mechanisms by which NF-κB-dependent gene transcription are regulated and highlight the potential for manipulation of p50:HDAC1 interactions to bring about experimental modulation of chronic inflammation and pathologies associated with dysregulated neutrophil accumulation and activation

Insights from Engineering a Community-Family Partnership Project

The objective of this three-year National Science Foundation’s Innovative Technology Experiences for Students and Teachers (NSF-ITEST) project is to develop, implement, and refine a program for integrating engineering design practices with an emphasis on emerging technologies (i.e., making, DIY electronics) into home environments of families with a child in grade 3-6 from under-resourced communities. This project has two components. Each family (1) defines a home- or community-based problem and creates a prototype to improve the lives of self or others; and (2) engages in low-cost engineering design kits in their home environments. This paper presents findings from two years of interview data, as well video data collected in project sessions and home environments from 21 families. Results are presented as highlights of finding from on-going analyses to address three research aims

CMB-S4 Science Book, First Edition

This book lays out the scientific goals to be addressed by the next-generation ground-based cosmic microwave background experiment, CMB-S4, envisioned to consist of dedicated telescopes at the South Pole, the high Chilean Atacama plateau and possibly a northern hemisphere site, all equipped with new superconducting cameras. CMB-S4 will dramatically advance cosmological studies by crossing critical thresholds in the search for the B-mode polarization signature of primordial gravitational waves, in the determination of the number and masses of the neutrinos, in the search for evidence of new light relics, in constraining the nature of dark energy, and in testing general relativity on large scales

Observing the Evolution of the Universe

How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the universe. Through detailed measurements one may address everything from the physics of the birth of the universe to the history of star formation and the process by which galaxies formed. One may in addition track the evolution of the dark energy and discover the net neutrino mass. We are at the dawn of a new era in which hundreds of square degrees of sky can be mapped with arcminute resolution and sensitivities measured in microKelvin. Acquiring these data requires the use of special purpose telescopes such as the Atacama Cosmology Telescope (ACT), located in Chile, and the South Pole Telescope (SPT). These new telescopes are outfitted with a new generation of custom mm-wave kilo-pixel arrays. Additional instruments are in the planning stages.Comment: Science White Paper submitted to the US Astro2010 Decadal Survey. Full list of 177 author available at http://cmbpol.uchicago.ed

Comparing and combining the Saskatoon, QMAP and COBE CMB maps

We present a method for comparing and combining maps with different resolutions and beam shapes, and apply it to the Saskatoon, QMAP and COBE/DMR data sets. Although the Saskatoon and QMAP maps detect signal at the 21 sigma and 40 sigma levels, respectively, their difference is consistent with pure noise, placing strong limits on possible systematic errors. In particular, we obtain quantitative upper limits on relative calibration and pointing errors. Splitting the combined data by frequency shows similar consistency between the Ka- and Q-bands, placing limits on foreground contamination. The visual agreement between the maps is equally striking. Our combined QMAP+Saskatoon map, nicknamed QMASK, is publicly available at www.hep.upenn.edu/~xuyz/qmask.html together with its 6495x6495 noise covariance matrix. This thoroughly tested data set covers a large enough area (648 square degrees -- currently the largest degree-scale map available) to allow a statistical comparison with COBE/DMR, showing good agreement.Comment: Replaced to match accepted PRD version. 12 pages, 11 figs.
