Occupation and Time-Use: The Narratives of One Individual with Tetraplegia

Background: Successful health-management habits of individuals with tetraplegia have correlated with better quality of life and occupational engagement. Objectives: Little is known about the experience of time-use during these practices and the influence these routines have on participation in other meaningful occupations. This study aimed to explore the stories an individual with tetraplegia has about time-use in health management practices, influences on time-use, and feelings about quality of life and life satisfaction. Methodology: Narrative inquiry was used to explore the stories of time-use of one individual living with tetraplegia. Findings: Eleven interpretive stories were thematically represented illustrating the complexity of occupation, how personal meaning was attached to time-intensive basic ADL and health management practices, and perspectives on time-use influences outside these routines. Conclusion: Exploring narratives of individuals with tetraplegia can help to better understand personal meaning attached to occupation and the occupation-context interactions that influence occupational performance, experience, and engagement

Doing It Right: OT Meeting Population Needs with COVID-19

In 2010, the U.S. Department of Health and Human Services (HHS) identified strategic goals for health promotion and disease prevention in Healthy People 2020. Some of the overarching goals were to “achieve health equity, eliminate disparities, and improve the health of all groups” in order to address inequities tied to race and ethnicity, gender, socioeconomic status, geography, and disability (p. 3). The plan also targeted health disparities by recognizing social determinants of health and creating “social and physical environments that promote good health,” including the development of policy and programs (HHS, 2010, p. 3). Health disparities are population specific and quantify “differences in disease rates, health outcomes, and access to health care services” (American Occupational Therapy Association [AOTA], 2013, p. S48). In times of crisis, vulnerable populations may be particularly susceptible to disease, illness, and mortality because of health disparities related to social and environmental barriers and determinants of health. AOTA’s official stand on nondiscrimination and inclusion is that every individual be treated fairly and equitably (AOTA, 2014b); that an individual’s culture, race, ethnicity, age, and capacities be respected; and that all occupational therapy personnel avoid prejudice and bias (AOTA, 2015). As a profession, occupational therapy promotes access and inclusion and limits health disparities in daily practice. Advocacy is a critical role and value of the profession for promoting resilience for populations based on health equity and occupational justice

Radio continuum observations of local star-forming galaxies using the Caltech Continuum Backend on the Green Bank Telescope

We observed radio continuum emission in 27 local (D < 70 Mpc) star-forming galaxies with the Robert C. Byrd Green Bank Telescope between 26 GHz and 40 GHz using the Caltech Continuum Backend. We obtained detections for 22 of these galaxies at all four sub-bands and four more marginal detections by taking the average flux across the entire bandwidth. This is the first detection (full or marginal) at these frequencies for 22 of these galaxies. We fit spectral energy distributions (SEDs) for all of the four-sub-band detections. For 14 of the galaxies, SEDs were best fit by a combination of thermal free-free and nonthermal synchrotron components. Eight galaxies with four-sub-band detections had steep spectra that were only fit by a single nonthermal component. Using these fits, we calculated supernova rates, total number of equivalent O stars, and star formation rates within each ~23 arcsecond beam. For unresolved galaxies, these physical properties characterize the galaxies' recent star formation on a global scale. We confirm that the radio-far-infrared correlation holds for the unresolved galaxies' total 33 GHz flux regardless of their thermal fractions, though the scatter on this correlation is larger than that at 1.4 GHz. In addition, we found that for the unresolved galaxies, there is an inverse relationship between the ratio of 33 GHz flux to total far-infrared flux and the steepness of the galaxy's spectral index between 1.4 GHz and 33 GHz. This relationship could be an indicator of the timescale of the observed episode of star formation.Comment: 36 pages, 9 figures; accepted for publication in ApJ.

Unveiling Extragalactic Star Formation Using Radio Recombination Lines: An Expanded Very Large Array Pilot Study With Ngc 253

Radio recombination lines (RRLs) are powerful, extinction-free diagnostics of the ionized gas in young, star-forming regions. Unfortunately, these lines are difficult to detect in external galaxies. We present the results of Expanded Very Large Array (EVLA) observations of the RRL and radio continuum emission at 33 GHz from NGC 253, a nearby nuclear starburst galaxy. We detect the previously unobserved H58{alpha} and H59{alpha} RRLs and make simultaneous sensitive measurements of the continuum. We measure integrated line fluxes of 44.3 {+-} 0.7 W m{sup -2} and 39.9 {+-} 0.8 W m{sup -2} for the H58{alpha} and H59{alpha} lines, respectively. The thermal gas in NGC 253 is kinematically complex with multiple velocity components. We constrain the density of the thermal gas to (1.4-4) x 10{sup 4} cm{sup -3} and estimate an ionizing photon flux of 1 x 10{sup 53} s{sup -1}. We use the RRL kinematics and the derived ionizing photon flux to show that the nuclear region of NGC 253 is not gravitationally bound, which is consistent with the outflow of gas inferred from the X-ray and H{alpha} measurements. The line profiles, fluxes, and kinematics of the H58{alpha} and H59{alpha} lines agree with those of RRLs at different frequencies confirming themore » accuracy of the previous, more difficult, high-frequency observations. We find that the EVLA is an order of magnitude more efficient for extragalactic RRL observations than the Very Large Array. These observations demonstrate both the power of the EVLA and the future potential of extragalactic RRL studies with the EVLA.« les

Participatory Design of Purdue University’s Active Learning Center Final Report

Purdue University’s commitment to active learning requires facilities that support small-­‐group work, peer learning, the use of technology, and other classroom innovations. The Active Learning Center is intended to provide classroom space combined seamlessly with library space to meet these needs. Members of the Libraries faculty and staff conducted a series of information-­‐gathering activities to gain insight into the range of activities, work practices and preferences that the new building must support. It is our hope that the building will indeed support these activities, serve as a centrally located, flagship building for Purdue University, and support and inspire learning for years to come
