Previous issue date: 2016-05-13Women, African Americans, Latinos and Native Americans are underrepresented in STEM at the high school, college, and careers levels. For underrepresented groups, many efforts may come too late to address underlying problems such as perceived lack of ability and lack of exposure. Out of school, semi-structured robotics programs with embedded community informatics (CI) practices have demonstrate great potential for increasing STEM access, exposure, and interest for all students. Yet, while programs of this kind have demonstrated promising outcomes for increasing STEM interest early in the STEM education pipeline, gaining access to tools and resources for underrepresented communities students can be very challenging.
This qualitative research study uses a constructionists grounded theory methodology to examine what happens when a group of African American parents attempt to gain access to resources and implement STEM programming (a robotics project) outside of a traditional school setting.
This study employ the theoretical frameworks of community cultural wealth, bridging and bonding social capital, and possible-selves, in examining the challenges and triumphs of African American parents in establishing a quality robotics program for their middle school level African American children in a small urban Midwest community.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-08-01The student, Angela Slates, accepted the attached license on 2016-05-12 at 12:29.Embargo set by: Seth Robbins for item 95412

The Role of Validation Experiences and Sense of Belonging in Academic Self-Concept and Intent to Persist Among Four-Year College Students
No full textResearch indicates that historically underrepresented college students are more likely to report alienating campus climates which can contribute to decreased sense of belonging and wellbeing. In turn, a lack of a sense of belonging and poor mental health may lead to decreased academic engagement and increased likelihood of attrition. Theoretical and empirical literature on critical race theory (CRT), validation, and sense of belonging identifies key factors across individual and institutional levels that influence student wellbeing and academic outcomes without relying on a deficit-based framework. Using an interactional, ecological conceptual framework drawing together CRT, validation theory, and sense of belonging my study further explores the relationships between academic validation, interpersonal validation, and sense of belonging and academic self-concept and persistence outcomes. Three years of survey data, 2015-2017, from four-year institutions were drawn from the Diverse Learning Environments (DLE) survey administered by the Higher Education Research Institute (HERI). The primary independent variables include academic validation, interpersonal validation, and sense of belonging. The outcome variables are academic self-concept and intent to persist operationalized as whether a student has considered dropping out of their program and whether they plan to attend a graduate program. Covariates include student demographics, identity, and enrollment; student and institutional engagement; and institutional characteristics and climate variables. The primary method of analysis was ordinary least squares (OLS) and logistic regression models. Subgroup analyses were conducted to determine any overall differences among groups and specific differences in the effects of primary predictors. Analyses were conducted using IBM SPSS 26. Across iv
all outcomes, primary independent variables or focal factors and student demographic, identity, and enrollment variables explained the greatest variation in academic self-concept scores and persistence. However, important student and institutional engagement and institutional characteristics and climate factors were also identified. The subgroup analyses did not identify consistently meaningful or significant differences in the effects of the primary predictors. Implications focus on theory, policies, and practices to enhance the implicit or hidden curriculum.

No full textPOSSIBLE SIGNATURES OF CONFORMATIONAL ISOMERIZATION IN THE HIGH RESOLUTION INFRARED SPECTRUM OF 2-FLUOROETHANOL
No full textAuthor Institution: Department of Chemistry, University of VirginiaWe have measured the high resolution (5 MHz) infrared spectrum of the asymmetric(F) stretch of 2-fluoroethanol near using an electric-resonance optothermal molecular beam spectrometer. The infrared spectrum has been assigned using microwave-infrared double-resonance spectroscopy techniques. The infrared spectrum originates in rotational level of the most stable conformer, denoted , where both internal rotors (C-C and C-O) are is a gauche conformation. The barrier to conformational isomerization is approximately . Above conformations are accessible, Tt and Tg. Two features of the infrared spectrum may indicate conformational isomerization following excitation of the C-H stretch: 1) The degeneracy of the two enantiomers is lifted in the infrared spectrum. For 2-fluoroethanol, the degeneracy is lifted only when highly torsionally excited states, or states from the Tt conformation, are involved in the dynamics. 2) There is a strong correlation between rotational states assigned to separate levels of near-degenerate -asymmetry doublets indicating energy flow between these slates. These properties of the single-photon infrared spectrum are discussed in the context of subsequent infrared-microwave double-resonance spectroscopy measurements which unambiguously demonstrate conformational isomerization following C-H stretch excitation
Hydrogeological investigations by surface geoelectrical method in hard rock formation - a case study
No full textThe major portion of Kermanshah, a state in the west of Iran, comprises hard rocks such as limestone, schist,
marly limestone, slates, diorites and andesites etc. The sedimentary rocks are repeatedly folded and faulted. The depth
of the basement topography is shallow to deep in hard rock terrain. The state possesses an area of 24,434 sq. km.
The present study aims at delineating the hydrogeological framework in hard rock terrain by using interpreted results

Three-Color Triple Resonance Spectroscopy of Highly Excited {ng} Rydberg States of NO
No full textAuthor Institution: Department of Chemistry, Faculty of Science, Tohoku University; Department of Chemistry, Institute for Molecular ScienceLaser multiphoton ionization spectroscopy of highly excited {ng} Rydberg states (n=11-67, =0 and 1) of NO was performed. Three-color triple resonance technique was used for rotationally state selective excitation of high {ng} Rydberg states. The observed term values were well reproduced by theoretical calculation based on the long range force model. The experimental evidence for fast autoionization decay in the {ng} Rydberg slates, which has been theoretically predicted, was found at first. Not only autoionization, but also predissociation decay was observed
The slate from Jenków (Lower Silesian) and the possibilities of its use
No full textArtykuł prezentuje wyjątkowe właściwości kopaliny ze złoża Jenków na Dolnym Śląsku. Na podstawie danych z dokumentacji geologicznych przedstawiono zróżnicowanie parametrów petrofizycznych w trzech odmianach kopaliny, a także zmienność składu mineralogiczno-petrograficznego. Zidentyfikowano główne i podrzędne komponenty dwóch odmian kopaliny, łupkowej i łupkowo-fyllitowej. Na podstawie obserwacji makroskopowych oceniono zmienność barwy, połysku, jak również cech strukturalno-
teksturalnych łupków i fyllitów. Oceniono właściwości dekoracyjne kopaliny złoża Jenków według klasyfikacji dekoracyjności zaproponowanej przez zespół profesora Jana Bromowicza. Wśród kamieni budowlanych łupki szarogłazowe i fyllity pochodzące ze złoża Jenków stanowią wyjątkową kopalinę ze względu na wysokie walory dekoracyjne i naturalną podzielność płytową, które determinują ich specyficzne walory użytkowe. Łupek jenkowski wyróżnia się szeroką gamą zastosowań jako łupany kamień elewacyjny, murowy czy ścieżkowy, a rozpropagowanie jego wyjątkowych walorów jest ostatecznym celem tej pracy.The paper presents the unique values of the stones from the Jenków deposit in Lower Silesia. Based on the data contained in geological reports the author presents the variability of the physical and mechanical properties of three rock types and the variability of their mineral and petrographic composition. Major and minor components of two essential, unweathered types of the Jenków rocks, i.e., slates and slates-phyllites, have been described. The changes of rock colours, lustre and also structural and textural features have been determined based on macroscopic observations. Decorative properties of the rocks from the Jenków deposit have been evaluated according to the classification proposed by Professor Jan Bromowicz’s group. Among building stones, greywacke slates and phyllites from Jenków represent a unique material because of their highly decorative values and natural splitting into ashlar slabs. Due to the latter feature, the Jenków rocks can be used to manufacture a wide range of stone products, including wall facing ashlar slabs and various other slabs applicable in outdoor small architecture, e.g. in parks or gardens. The photographs presented are only few examples of a possible utilization of these valuable rocks
