Exploring the meanings of artistic occupation for women living with chronic illness: A comparison of template and interpretative phenomenological approaches to analysis
No full text(Brief Summary)
This article is based on my experience of carrying out two
studies that explored the meanings of artistic occupations
(in particular, textile arts) for women who were living with
long-term health problems (Reynolds 1997, Reynolds and
Prior 2003). Inquiry into the meanings of occupation for
people in the community who are coping with illness and
life transitions is a growing area of occupational therapy
research (for example, Christiansen et al 1999, Jonsson et al
2001, Lyons et al 2002). A better understanding of the
phenomenology of occupation may help to inform
professional practice
The D/H Ratio toward PG 0038+199
No full textInternational audienceWe determine the D/H ratio in the interstellar medium toward the DO white dwarf PG 0038+199 using spectra from the Far Ultraviolet Spectroscopic Explorer (FUSE), with ground-based support from Keck HIRES. We employ curve-of-growth, apparent optical depth, and profile-fitting techniques to measure the column densities and limits of many other species (H2, Na I, C I, C II, C III, N I, N II, O I, Si II, P II, S III, Ar I, and Fe II), which allows us to determine related ratios such as D/O, D/N, and the H2 fraction. Our efforts are concentrated on measuring gas-phase D/H, which is key to understanding Galactic chemical evolution, and comparing it to predictions from big bang nucleosynthesis. We find column densities logN(HI)=20.41+/-0.08, logN(DI)=15.75+/-0.08, and logN(H2)=19.33+/-0.04, yielding a molecular hydrogen fraction of 0.14+/-0.02 (2 σ errors), with an excitation temperature of 143+/-5 K. The high H I column density implies that PG 0038+199 lies outside of the Local Bubble; we estimate its distance to be 297+164-104 pc (1 σ). [DI+HD]/[HI+2H2] toward PG 0038+199 is 1.91+0.52-0.42×10-5 (2 σ). There is no evidence of component structure on the scale of Δv>8 km s-1, based on Na I, but there is marginal evidence for structure on smaller scales. The D/H value is high compared to the majority of recent D/H measurements but consistent with the values for two other measurements at similar distances. D/O is in agreement with other distant measurements. The scatter in D/H values beyond ~100 pc remains a challenge for Galactic chemical evolution. This paper is dedicated in memory of Ervin J. Williger, father of the first author, who passed away on 2003 September 13. His enthusiastic support and encouragement were essential to its successful completion.

Post-modification of peptoid side chains: [3+2] cycloaddition of nitrile oxides with alkenes and alkynes on the solid-phase
No full textTest and application of a vegetation-based CO2 and CH4 flux estimate from three ombrogenic and topogenic peatlands in Southern Germany
No full textA stabilisation and restoration of peatlands is seen as a sustainable strategie for climate change mitigation. To find the most suitable target areas, greenhouse gas fluxes have to be quantified. A vegetation-based flux estimate is seen as cost-effective alternative to avoid time consuming and expensive flux measurements. The present study aims to define current obstacles and limitations to a vegetation-based flux estimate and define a possible scope for vegetation-based flux estimates in Baden-Württemberg. A case study was performed in three ombrogenic and topogenic mires in Southern Germany using the tools Greenhouse Gas Emission Site Type (GEST) for non-forest sites and IPCC’s ‘Good Practise Guidance for Land Use, Land Use Change and Forestry’(GPG-LULUCF) for forest sites. The study was limited to carbon dioxide (CO2) and methane (CH4) fluxes, shown as CO2 equivalents (CO2e). Based on 115 vegetation relevés, three vegetation classification systems on non-forest sites ‘vegetation forms’, ‘phytosociological plant communities’ and ‘Biotope types of Baden-Württemberg’ were compared to test if they can replace each other in a flux estimate. Calculation parameters for forest-sites were chosen for the study area. A greenhouse gas balance was established for the study area. The reviewed vegetation classification systems showed inconsistent overlaps. Hence, the vegetation classification systems were considered to be not completely compatible. As descripition of vegetation forms was considered to be insufficient for Southern Germany, an application of vegetation-based CO2 and CH4 flux estimates was considered to be difficult in Baden-Württemberg. Mean CO2 and CH4 emissions of 9,7 t CO2e ha-1 yr-1 were estimated in the study area. Emissions from forested peat were smaller than from mire and from grassland on peat. However, the selection of parameters for GPG-LULUCF and associated inaccuracies influenced the estimate. Footpaths and roads, watercourses and lakes, pastures, cropland and clearcut were not considered and N2O emissions were excluded from the estimate. Considering these limitations of the estimate, vegetation-based carbon estimates should be verified and refined before a statewide application
Nivel de afrontamiento y grado de ansiedad de los familiares del paciente hospitalizado en la unidad de cuidados intensivos de un Hospital Nacional Lima - 2022

afrontamiento y el grado de ansiedad de los familiares de pacientes
hospitalizados en la unidad de cuidados intensivos en un hospital nacional.
investigación de tipo descriptiva correlacional y de diseño transversal,
denominado así porque analiza y recopila datos de las variables durante un
determinado periodo de tiempo la muestra fue tomado por conveniencia el número
total fueron 50 familiares de pacientes críticos. Para la recolección de la información
del presente estudio de investigación, se utilizó la escala de medición del Nivel de
Afrontamiento del familiar cuidador EMNAFC (ANEXO N°01) asimismo también la
escala de medición del nivel de afrontamiento cuyos autores son Rudolf H. Moos y B.
Moos (1993), modificada por Mikulic I. (2007), adaptada por Mauricio (2013);
adaptada por las autoras y para medir el grado de ansiedad se utilizó la escala fue
elaborada por Hamilton (HARS-1999). En la cual se determina que el 72,0% de los
familiares tienen un afrontamiento de nivel medio donde el 56,0% presentan un
grado de ansiedad moderado, el 10,0% leve grado de ansiedad y el 6,0% grave grado
de ansiedad; mientras el 16,0% tienen un afrontamiento de nivel alto donde el 12,0%
presentan un grado de ansiedad leve y el 4,0% un grado de ansiedad moderado; por
último, el 12,0% tienen un afrontamiento de nivel bajo y un grado de ansiedad grave.
Al realizar la prueba de Chi cuadrado se obtuvo un valor de significancia de p:
0,000, aceptando la hipótesis general. Se concluyó que el grado de ansiedad tiene
