    Purdue at 150: A Visual History of Student Life by David M. Hovde, Adriana Harmeyer, Neal Harmeyer, and Sammie L. Morris tells Purdue’s story through rare images, artifacts, and words. Authors culled decades of student papers, from scrapbooks, yearbooks, letters, and newspapers to historical photographs and memorabilia preserved in the Purdue University Libraries Virginia Kelly Karnes Archives and Special Collections. Many of the images and artifacts included have never been published, presenting a unique history of Purdue University from the student perspective. Purdue at 150 is organized by decade, presenting a scrapbook-like experience of viewing over 400 rare photographs, documents, and artifacts alongside critical contextual information. Each chapter provides a decadal historical sketch of Purdue University, offering insight into the institution’s unique culture while incorporating campus responses to major national events such as world wars and the Great Depression. Spotlight sections highlight Purdue firsts, including the first graduates of programs, the growth and development of the international student population at Purdue, the creation of significant student organizations, and the foundations of both old and new campus traditions. This curated journey through the personal experiences, spaces, and events of Purdue’s history not only celebrates major accomplishments and acknowledges the contributions Purdue has made to society, but it also explores some of the challenges and tragedies that shaped Indiana’s land-grant university. As a result, Purdue at 150 connects the identity and character of the University of 1869 to the University of 2019 and beyond, as told through the stories of its students. Running throughout this journey is the enduring vision of the land-grant institution and its impact on society, as seen through the material culture of Boilermakers from around the world.https://docs.lib.purdue.edu/purduepress_previews/1024/thumbnail.jp

    Context: Residents experiencing pain, anxiety, and distressing behaviours, often in conjunction with mental health diagnoses and dementia, can be challenging for staff in long-term care facilities and may result in jeopardising resident and staff safety, quality of life, staff delivery of care, and overuse of psychotropic medications. Objective: Describe the effects of three holistic interventions (hand portion of the ‘M’ Technique®, aromatherapy, and energy healing) to reduce pain, anxiety, and distressing behaviours in long-term care residents. Method: Pragmatic secondary analysis of pre- and post-intervention quantitative and qualitative data. Findings: Staff administered a total of 363 individual sessions using the ‘M’ Technique® for hands, aromatherapy, and/or energy healing to 75 residents who were able to indicate their pain and/or anxiety levels before and after a session. Results indicate significant differences in decreased pain by session, decreased anxiety by session, decreased pain by person, and decreased anxiety by person. Qualitative results, primarily gathered from an additional 1,024 sessions in which residents were unable to use pain and anxiety scales, indicate a decrease in distressing behaviours and overall improvement of milieu. Limitations: We collected data as part of a quality improvement programme without the intent of being published as a research study. It is difficult to assess the reliability and validity of self-reported quantitative pain and anxiety scales for people with dementia. Implications: Holistic interventions, including the ‘M’ Technique for hands, aromatherapy, and/or energy healing, show promise in reducing pain, anxiety, and distressing behaviours in residents of long-term care facilities, along with improvements in the facilities’ environment

    The Consortium for Policy Research in Education (CPRE) at the University of Pennsylvania was contracted by the National Center on Education and the Economy (NCEE) in 1998 to conduct the external evaluation of the America's Choice school design. CPRE designed and conducted a series of targeted studies on the implementation and impacts of the America's Choice design. This report coincides with the publication of three separate studies by CPRE on the impact of America's Choice in a number of districts across the country using a variety of quantitative and analytic approaches. Those impact analyses and a stand-alone piece on classroom observations conducted in Cohort 4 schools can be viewed as separate pieces or as complements to the information presented in this report. Another recent CPRE publication from fall 2001 is a widely distributed report entitled, Instructional Leadership in a Standards-based Reform, a companion piece to both the impact reports and this report

    Nonlinear magneto-optical rotation with frequency-modulated light in the geophysical field range

    Full text link
    Recent work investigating resonant nonlinear magneto-optical rotation (NMOR) related to long-lived (\tau\ts{rel} \sim 1 {\rm s}) ground-state atomic coherences has demonstrated potential magnetometric sensitivities exceeding 10−11G/Hz10^{-11} {\rm G/\sqrt{Hz}} for small (≲1μG\lesssim 1 {\rm \mu G}) magnetic fields. In the present work, NMOR using frequency-modulated light (FM NMOR) is studied in the regime where the longitudinal magnetic field is in the geophysical range (∼500mG\sim 500 {\rm mG}), of particular interest for many applications. In this regime a splitting of the FM NMOR resonance due to the nonlinear Zeeman effect is observed. At sufficiently high light intensities, there is also a splitting of the FM NMOR resonances due to ac Stark shifts induced by the optical field, as well as evidence of alignment-to-orientation conversion type processes. The consequences of these effects for FM-NMOR-based atomic magnetometry in the geophysical field range are considered.Comment: 8 pages, 8 figure

    A remotely interrogated all-optical Rb-87 magnetometer

    Get PDF
    Atomic magnetometry was performed at Earth's magnetic field over a free-space distance of ten meters. Two laser beams aimed at a distant alkali-vapor cell excited and detected the Rb-87 magnetic resonance, allowing the magnetic field within the cell to be interrogated remotely. Operated as a driven oscillator, the magnetometer measured the geomagnetic field with less than or similar to 3.5 pT precision in a similar to 2 s data acquisition; this precision was likely limited by ambient field fluctuations. The sensor was also operated in self-oscillating mode with a 5.3 pT root Hz noise floor. Further optimization will yield a high-bandwidth, fully remote magnetometer with sub-pT sensitivity.

    Submillimeter absorption from SH+, a new widespread interstellar radical, 13CH+ and HCl

    Full text link
    We have used the Atacama Pathfinder Experiment 12 m telescope (APEX) to carry out an absorption study of submillimeter wavelength rotational ground-state lines of H35Cl, H37Cl, 13CH+, and, for the first time, of the SH+ radical (sulfoniumylidene or sulfanylium). We detected the quartet of ground-state hyperfine structure lines of SH+ near 683 GHz with the CHAMP+ array receiver against the strong continuum source Sagittarius B2, which is located close to the center of our Galaxy. In addition to absorption from various kinematic components of Galactic center gas, we also see absorption at the radial velocities belonging to intervening spiral arms. This demonstrates that SH+ is a ubiquitous component of the diffuse interstellar medium. We do not find clear evidence for other SH+ lines we searched for, which is partially due to blending with lines from other molecules. In addition to SH+, we observed absorption from H35Cl, H37Cl, and 13CH+. The observed submillimeter absorption is compared in detail with absorption in 3 mm transitions of H13CO+ and c-C3H2 and the CO J = 1-0 and 3-2 transitions.Comment: 17 pages, 9 figure

    <p>Abstract</p> <p>Background</p> <p>Perceived milk intolerance is a common complaint, and tests for lactose malabsorption (LM) are unreliable. This study assesses the agreement between diagnostic tests for LM and describes the diagnostic properties of the tests.</p> <p>Methods</p> <p>Patients above 18 years of age with suspected LM were included. After oral intake of 25 g lactose, a combined test with measurement of serum glucose (s-glucose) and hydrogen (H2) and methane (CH4) in expired air was performed and symptoms were recorded. In patients with discrepancies between the results, the combined test was repeated and a gene test for lactose non-persistence was added. The diagnosis of LM was based on an evaluation of all tests. The following tests were compared: Increase in H2, CH4, H2+CH4 and H2+CH4x2 in expired air, increase in s-glucose, and symptoms. The agreement was calculated and the diagnostic properties described.</p> <p>Results</p> <p>Sixty patients were included, seven (12%) had LM. The agreement (kappa-values) between the methods varied from 0.25 to 0.91. The best test was the lactose breath test with measurement of the increase in H2 + CH4x2 in expired air. With a cut-off level < 18 ppm, the area under the ROC-curve was 0.967 and sensitivity was 100%. This shows that measurement of CH4 in addition to H2 improves the diagnostic properties of the breath test.</p> <p>Conclusion</p> <p>The agreement between commonly used methods for the diagnosis of LM was unsatisfactory. A lactose breath test with measurement of H2 + CH4x2 in expired air had the best diagnostic properties.</p
