An autoethnography of lifestories recorded on the community radio on the island of Barra
In agreeing with Geertzâs claim that culture is experiential (1973), I aim to present an interpretation of a lived experience. It is an autoethnographic reflection of my experience as a volunteer radio host for the community radio station on the island of Barra in the Outer Hebrides of Scotland. At the heart of my argument is spoken language and its meaning. From a selection of themes of transcribed lifestory interviews, I aim to show that culture, diachronically shaped in the islandâs collective historical experience of its past relationship to the sea, transforms itself through language to create a coherency of our present living experience. Indeed, my argument is that the collective conceptualisation of community and tradition, and the more individualised concept of identity, as conduits of culture, are constructed through contextually significant linear and non-linear narrative language, which is the result of temporal, ever-changing phenomenological processes. This synchronic interpretation, based on a snapshot of a collective public space, uses a critical discourse analysis of the islandâs oral history to demonstrate how lifestory narratives reflect and refract coherency of a historical specific time. In such slightly skewed reflections, the locality finds itself. But in its refracted form, it moves beyond the parochial into territory where themes uncover age gender differences. The differentiation of meaning produces a coherency that is echoed in feminist discourse. Looking through the theoretical lenses of anthropological and sociological perspectives, I argue that in the construction of lifestory narratives, the power relationships of a wider capitalist society are embedded, and, as such, reflect our lived experience, which gives meaning to what we understand as culture
Identification of diagnostic upper gastrointestinal cancer tissue typeâspecific urinary biomarkers
Several potential urinary biomarkers exhibiting an association with upper gastrointestinal tumour growth have been previously identified, of which S100A6, S100A9, rabenosynâ5 and programmed cell death 6âinteracting protein (PDCD6IP) were further validated and found to be upregulated in malignant tumours. The cancer cohort from our previous study was subclassified to assess whether distinct molecular markers can be identified for each individual cancer type using a similar approach. Urine samples from patients with cancers of the stomach, oesophagus, oesophagogastric junction or pancreas were analysed by surfaceâenhanced laser desorption/ionizationâtimeâofâflight mass spectrometry using both CM10 and IMAC30 (Cu2+âcomplexed) chip types and LCâMS/MSâbased mass spectrometry after chromatographic enrichment. This was followed by protein identification, pattern matching and validation by western blotting. We found 8 m/z peaks with statistical significance for the four cancer types investigated, of which m/z 2447 and 2577 were identified by pattern matching as fragments of cathepsinâB (CTSB) and cystatinâB (CSTB); both molecules are indicative of pancreatic cancer. Additionally, we observed a potential association of upregulated αâ1âantichymotrypsin with pancreatic and gastric cancers, of PDCD6IP, vitelline membrane outer layer protein 1 homolog (VMO1) and triosephosphate isomerase (TPI1) with oesophagogastric junctional cancers, and of complement C4âA, prostatic acid phosphatase, azurocidin and histoneâH1 with oesophageal cancer. Furthermore, the potential pancreatic cancer biomarkers CSTB and CTSB were validated independently by western blotting. Therefore, the present study identified two new potential urinary biomarkers that appear to be associated with pancreatic cancer. This may provide a simple, nonâinvasive screening test for use in the clinical setting.</p

Evaluating the impact of patients' online access to doctors' visit notes: designing and executing the OpenNotes project
Background: Providers and policymakers are pursuing strategies to increase patient engagement in health care. Increasingly, online sections of medical records are viewable by patients though seldom are clinicians' visit notes included. We designed a one-year multi-site trial of online patient accessible office visit notes, OpenNotes. We hypothesized that patients and primary care physicians (PCPs) would want it to continue and that OpenNotes would not lead to significant disruptions to doctors' practices. Methods/Design: Using a mixed methods approach, we designed a quasi-experimental study in 3 diverse healthcare systems in Boston, Pennsylvania, and Seattle. Two sites had existing patient internet portals; the third used an experimental portal. We targeted 3 key areas where we hypothesized the greatest impacts: beliefs and attitudes about OpenNotes, use of the patient internet portals, and patient-doctor communication. PCPs in the 3 sites were invited to participate in the intervention. Patients who were registered portal users of participating PCPs were given access to their PCPs' visit notes for one year. PCPs who declined participation in the intervention and their patients served as the comparison groups for the study. We applied the RE-AIM framework to our design in order to capture as comprehensive a picture as possible of the impact of OpenNotes. We developed pre- and post-intervention surveys for online administration addressing attitudes and experiences based on interviews and focus groups with patients and doctors. In addition, we tracked use of the internet portals before and during the intervention. Results: PCP participation varied from 19% to 87% across the 3 sites; a total of 114 PCPs enrolled in the intervention with their 22,000 patients who were registered portal users. Approximately 40% of intervention and non-intervention patients at the 3 sites responded to the online survey, yielding a total of approximately 38,000 patient surveys. Discussion: Many primary care physicians were willing to participate in this "real world" experiment testing the impact of OpenNotes on their patients and their practices. Results from this trial will inform providers, policy makers, and patients who contemplate such changes at a time of exploding interest in transparency, patient safety, and improving the quality of care
Hubble Space Telescope Grism Spectroscopy of Extreme Starbursts Across Cosmic Time: The Role of Dwarf Galaxies in the Star Formation History of the Universe
Near infrared slitless spectroscopy with the Wide Field Camera 3, onboard the
Hubble Space Telescope, offers a unique opportunity to study low-mass galaxy
populations at high-redshift (1-2). While most high surveys are
biased towards massive galaxies, we are able to select sources via their
emission lines that have very-faint continua. We investigate the star formation
rate (SFR)-stellar mass () relation for about 1000 emission-line
galaxies identified over a wide redshift range of . We use the H emission as an accurate SFR indicator and correct
the broadband photometry for the strong nebular contribution to derive accurate
stellar masses down to . We focus here on a
subsample of galaxies that show extremely strong emission lines (EELGs) with
rest-frame equivalent widths ranging from 200 to 1500 \AA. This population
consists of outliers to the normal SFR- sequence with much higher
specific SFRs ( Gyr). While on-sequence galaxies follow a
continuous star formation process, EELGs are thought to be caught during an
extreme burst of star formation that can double their stellar mass in less than
Myr. The contribution of starbursts to the total star formation density
appears to be larger than what has been reported for more massive galaxies in
previous studies. In the complete mass range log()
and a SFR lower completeness limit of about 2 yr (10
yr) at (), we find that starbursts having
EW(H) 300, 200, and 100 A contribute up to , 18,
and 34 %, respectively, to the total SFR of emission-line selected sample at
. The comparison with samples of massive galaxies shows an increase
in the contribution of starbursts towards lower masses.Comment: 11 pages, 6 figures. The Astrophysical Journal, in pres
