An Educational Pathway for Geriatric Home Caregivers

The establishment of a multi-tiered educational pathway for geriatric home caregivers would support efforts to meet the needs of an increasing number of community dwelling older adults who require assistance with activities of daily living, while generating a cadre of qualified employees for an expanding non-medical private home care market. An educational pathway for geriatric home caregivers would also standardize the training of home care assistants while providing these individuals access to routine, high quality continuing education opportunities and the potential for career advancement. This issue brief provides two model educational pathways toward becoming a Geriatric Home Caregiver

An analytic model for redshift-space distortions

Understanding the formation and evolution of large-scale structure is a central problem in cosmology and enables precise tests of General Relativity on cosmological scales and constraints on dark energy. An essential ingredient is an accurate description of the pairwise velocities of biased tracers of the matter field. In this paper we compute the first and second moments of the pairwise velocity distribution by extending the Convolution Lagrangian Perturbation theory (CLPT) formalism of Carlson et al. (2012). Our predictions outperform standard perturbation theory calculations in many cases when compared to statistics measured in N-body simulations. We combine the CLPT predictions of real-space clustering and velocity statistics in the Gaussian streaming model of Reid & White (2011) to obtain predictions for the monopole and quadrupole correlation functions accurate to 2 and 4 per cent respectively down to <25Mpc/h for halos hosting the massive galaxies observed by SDSS-III BOSS. We also discuss contours of the 2D correlation function and clustering "wedges". We generalize the scheme to cross-correlation functions.Comment: 12 pages, 12 figures.

Interdisciplinary Research Experiences For Undergraduates: Two Mixed-Methods Studies

Despite the demand for a diverse STEM-educated population and workforce, college students have consistently turned away from these disciplines in large numbers, creating a persistent problem that many are trying to address. The aim of the National Science Foundation\u27s Research Experiences for Undergraduates (REU) program is to inspire, attract, and retain STEM majors. Funding supports undergraduate STEM students\u27 engagement in real-world research alongside STEM mentors. As colleges and universities compete for funding for REUs, it is important to understand the mechanisms within summer research programs that resonate most deeply with undergraduate STEM researchers. While many studies reveal strong correlations between research experiences and STEM aspirations, less is known about the mechanisms within REU programs that support these gains. My research used quantitative and qualitative self-reported data from 20 REU students, 18 of whom were underrepresented minorities in STEM. Over two summers, these students, in cohorts of ten, came to the University of Vermont to participate in a team-oriented, 10-week REU: Interdisciplinary Research on Human Impacts in the Lake Champlain Ecosystem. Two mixed-methods studies, guided by the frameworks of the theory of possible selves, theory of self-efficacy for research, and social cognitive career theory, revealed four important program mechanisms that gave rise to gains in research skills, confidence and self-efficacy for research, and STEM career aspirations, particularly for individuals from underrepresented minority groups in STEM. Findings suggest that the program fostered student capacity building within a safe, inclusive, and positive setting where students experienced what it feels like to be an active participant in the world of research. Within this context, critical mechanisms that gave rise to gains in research skills, confidence and self-efficacy for research, and STEM career aspirations included: (1) experiential education through interdisciplinary research experiences, (2) student independence and ownership balanced with expert researcher guidance and support, (3) formal and informal mentoring networks where students were mentored and where they mentored others, and (4) the establishment of an intentional learning community that advanced leadership, research skill building, perseverance, and reflection. Results from this research cannot be generalized beyond the context of the Lake Champlain REU, however, findings are in alignment with the body of literature that highlights the positive effects of REUs on STEM majors\u27 research skills, confidence and self-efficacy for research, and STEM career aspirations. Using mixed methods to identify and understand the within-program mechanisms that support student gains is a valuable new research approach for this field. Recognizing programmatic mechanisms across REU programs can lead to expansion, replication, and application of these models beyond one institution, resulting in more positive gains for more undergraduate STEM researchers

Nursing Knowledge of Heart Failure

Heart failure is a constellation of signs and symptoms reflecting a physiologic change in the hearts ability to keep up with demand. Heart failure is considered a global pandemic and is a complex disease that oftentimes is progressive. Heart failure is often associated with underlying coronary atherosclerosis, and its associated risks, including hypertension, diabetes mellitus, metabolic syndrome and dyslipidemia. To slow the progression and improve quality of life patients should be educated about the disease and in most health care settings nurses provide this education. However, nurses may lack sufficient knowledge of the processes that lead to heart failure. The purpose of this study was to determine the level of understanding nurses possess regarding heart failure, and whether additional evidence-based education regarding heart failure, sufficiently improves the nurses\u27 knowledge of heart failure. A pre/posttest design using a convenience sample of nurses at Marshall Health was used in this study. All nurses at Marshall Health cardiology and internal medicine were included without exclusion of hours worked or nursing degree. By using Rogers Diffusion of Innovations theory, nurses received heart failure education consisting of a video approximately 60 minutes long created by Qualidigm. Participants took a pretest just prior to the education video and one month later a posttest. The results showed that heart failure knowledge did increase from pre to posttest, however it was not significant (p= 0.277)

A 2.5% measurement of the growth rate from small-scale redshift space clustering of SDSS-III CMASS galaxies

We perform the first fit to the anisotropic clustering of SDSS-III CMASS DR10 galaxies on scales of ~ 0.8 - 32 Mpc/h. A standard halo occupation distribution model evaluated near the best fit Planck LCDM cosmology provides a good fit to the observed anisotropic clustering, and implies a normalization for the peculiar velocity field of M ~ 2 x 10^13 Msun/h halos of f*sigma8(z=0.57) = 0.450 +/- 0.011. Since this constraint includes both quasi-linear and non-linear scales, it should severely constrain modified gravity models that enhance pairwise infall velocities on these scales. Though model dependent, our measurement represents a factor of 2.5 improvement in precision over the analysis of DR11 on large scales, f*sigma8(z=0.57) = 0.447 +/- 0.028, and is the tightest single constraint on the growth rate of cosmic structure to date. Our measurement is consistent with the Planck LCDM prediction of 0.480 +/- 0.010 at the ~1.9 sigma level. Assuming a halo mass function evaluated at the best fit Planck cosmology, we also find that 10% of CMASS galaxies are satellites in halos of mass M ~ 6 x 10^13 Msun/h. While none of our tests and model generalizations indicate systematic errors due to an insufficiently detailed model of the galaxy-halo connection, the precision of these first results warrant further investigation into the modeling uncertainties and degeneracies with cosmological parameters.Comment: 24 pages, 20 figures, submitted to MNRAS. v2 is 27 pages, 23 figures, accepted by MNRA

Dating of Bush Turkey Rockshelter 3 in the Calvert Ranges establishes Early Holocene Occupation of the Little Sandy Desert, Western Australia

Systematic excavation of occupied rockshelters that occur in ranges along the Canning Stock Route of the Western Desert has seen the establishment of both a Pleistocene signal (c.24ka BP) as well as the fleshing out of a Holocene sequence. Recent dating of a perched rockshelter in the Calvert Ranges, east of the Durba Hills, has provided a Holocene record filling in previous occupational gaps from the Calvert Ranges. The extrapolated basal date of the site is in the order of 12,000 BP. Assemblages from this site illustrate repeated occupation through the Holocene with a notable shift in raw materials procured for artefact production and their technology of manufacture in the last 1000 years. Engraved and pigment art is thought to span the length of occupation of the shelter. The site illustrates a significant increase in the discard of cultural materials during the last 800 years, a trend observed at other desert sites. Much of the pigment art in this shelter seems likely to date to this most recent period

Complicated skin and soft tissue infections: literature review of evidence for and experience with daptomycin

Skin and soft tissue infections (SSTIs) are the second most common infection encountered in hospitals. Management decisions have become increasingly complex due to the prevalence of resistant pathogens, the wide array of licensed antimicrobials and the availability of potent oral agents and of out-patient parenteral antibiotic therapy. Daptomycin is one of the newer therapeutic agents licensed for complex SSTI management. Rapid cidality, good soft tissue penetration, once daily IV bolus administration and activity against resistant Gram-positive infections make daptomycin an attractive option both in hospitalized and community treated patients. A comprehensive review of the evidence for and experience with daptomycin and its use in SSTIs is presented

Tests of redshift-space distortions models in configuration space for the analysis of the BOSS final data release

Observations of redshift-space distortions in spectroscopic galaxy surveys offer an attractive method for observing the build-up of cosmological structure, which depends both on the expansion rate of the Universe and our theory of gravity. In preparation for analysis of redshift-space distortions from the Baryon Oscillation Spectroscopic Survey (BOSS) final data release we compare a number of analytic and phenomenological `streaming' models, specified in configuration space, to mock catalogs derived in different ways from several N-body simulations. The galaxies in each mock catalog have properties similar to those of the higher redshift galaxies measured by BOSS but differ in the details of how small-scale velocities and halo occupancy are determined. We find that all of the analytic models fit the simulations over a limited range of scales while failing at small scales. We discuss which models are most robust and on which scales they return reliable estimates of the rate of growth of structure: we find that models based on some form of resummation can fit our N-body data for BOSS-like galaxies above $30\,h^{-1}$Mpc well enough to return unbiased parameter estimates.Comment: 12 pages, 11 figures, matches version accepted by MNRA

Thomas Wolf c. Richard de Abingdon, 1293-1295 : a case study of legal argument

The project CLCLCL has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No. 740611)This essay examines the legal arguments in Wolf c. Abingdon, a tithes dispute from 1293–5 between the rector and the vicar of Aldington, Kent. The case records contain explicit citations to written law, a surprising find in a seemingly minor case. The presence of explicit citations in particular suggests first that the litigants had access to legal assistance in the provincial court, and second that advocates and possibly judges were turning to written legal sources to resolve disputed points. This essay shows how the litigants' arguments were constructed and determines whether or not these arguments were effective in court.PostprintPeer reviewe
