The Case against Mercury as the Angrite Parent Body (APB)

Angrites are not plausibly from Mercury based on their high FeO contents and ancient ages (e.g., [1]). Rather, the early crystallization ages of angrites argues for a small asteroidal-sized parent body for these meteorites (e.g., [2]). Despite this, recently it has been proposed that Mercury is the APB [3, 4, 5, 6]. Preserved corona and symplectite textures and the presence of 120 triple junctions in NWA 2999 have been cited as requiring a planetary origin [3, 4], with the symplectites in NWA 2999 resulting from rapid decompression during uplift via thrust faults on Mercury [4], and the coronas during subsequent cooling at low pressure. Glasses along grain boundaries and exsolution lamellae possibly indicative of rapid melting and cooling in NWA 4950 are cited as evidence of rapid decompression [6]. To explain the discrepancy between spectral observations of the Mercurian surface and the high FeO contents in angrites, an early (~4.5 Ga), collisionally-stripped FeO-rich basaltic surface has been suggested for Mercury [5, 6]

Personal Identity Changes of Female Cancer Survivors in Southern Appalachia

Navigating personal identity changes through the cancer journey can be challenging, especially for women in a culture that places emphasis on traditional gender roles and values close-knit families. Drawing on a story circule approach, this study examined the intersecting identities of female cancer survivors in southern Appalachia. Stories of 29 female Appalachian cancer survivors from Northeast Tennessee and Southwest Virginia were collected via a mixed methods approach in either a day-long story circule (N-26) or an in-depth interview (N=3). Transcripts from both phases were audio-recorded and transcribed verbatim; NVivo 8.0 facilitated qualitative content analysis of the data. Inductive analysis revealed that women in this study appeared in struggle with (1) maintaining place in the family, (2) mothering, and (3) navigating physical changes. Ideas of family versus self appeared to overlap and intertwine with how women in Appalachia navigate personal identify changes through the cancer journey

Navigating Family Cancer Communication: Communication Strategies of Female Cancer Survivors in Central Appalachia

In a multiphasic study, the stories of 29 female Appalachian cancer survivors were collected through either a day-long modified story circle event (n=26) or an in-depth interview (n=3). Qualitative content analysis was used to identify emergent themes in the data. The analysis revealed 5 types of family cancer communication including both pre-diagnosis and postdiagnosis cancer communication strategie

Omnibus Survivorship Narratives: Multiple Morbidities Among Female Cancer Survivors in South Central Appalachia

This study examines the illness narratives of female cancer survivors living in Southern Central Appalachia. Stories of 29 female Appalachian cancer survivors from northeastern Tennessee and southwcstmn Virginia were collected via a mixed methods approach in either a day-long story circle (n=26) or an in-depth interview (n=3), Qualitative content analysis was used to guide an inductive analysis of the tTanscript\u3c;, What emerged was that as participants survived cancer, they also survived other health conditions, their intorsccting stories yielding an omnibus survivorship narrative

Culturally Tailored Cancer Communication, Education, and Research: The Highways and Back Roads of Appalachia

We have varying experiences with Appalachia, yet we all agree that there is a unique relationship between Appalachians and cancer. Two of us are nurses who have worked with various communities. Two of us grew up here; 1 watched several of her relatives battle cancer in their Appalachian homes. All of us are scholars who want to talk with practitioners and researchers who are developing culturally tailored cancer control interventions. This goal to have a dialogue emerged after we had a series of discussions about cancer in Appalachia, discussions resulting in our developing a list of cultural traits that seem to be related to this region’s high cancer morbidity and morality (Table). For example, in one of our previous publications we describe the association between the traditional Appalachian oral culture and the cancer experience, finding that cancer stories appeared to pass from 1 generation to the next (1). In turn, these stories seem to affect some community members\u27 willingness to be screened. Our essay\u27s purpose is not to justify the elements presented in the Table. Rather, we write to consider the following: What are the advantages and disadvantages of making generalizations about a culture that has already been marginalized by overgeneralizations

Interaction of surface acoustic waves with a two-dimensional electron gas in the presence of spin splitting of the Landau bands

The absorption and variation of the velocity of a surface acoustic wave of frequency $f$= 30 MHz interacting with two-dimensional electrons are investigated in GaAs/AlGaAs heterostructures with an electron density $n=(1.3 - 2.8) \times 10^{11} cm^{-2}$ at $T$=1.5 - 4.2 K in magnetic fields up to 7 T. Characteristic features associated with spin splitting of the Landau level are observed. The effective g factor and the width of the spin-split Landau bands are determined: $g^* \simeq 5$ and $A$=0.6 meV. The greater width of the orbital-split Landau bands (2 meV) relative to the spin-split bands is attributed to different shielding of the random fluctuation potential of charged impurities by 2D electrons. The mechanisms of the nonlinearities manifested in the dependence of the absorption and the velocity increment of the SAW on the SAW power in the presence of spin splitting of the Landau levels are investigated.Comment: Revtex 5 pages + 5 EPS Figures, v.2 - minor corrections in text and pic

Mothered, Mothering & Motherizing in Illness Narratives: What Women Cancer Survivors in Southern Central Appalachia Reveal About Mothering-Disruption

Informed by a mothering-disruption framework, our study examines the illness narratives of women cancer survivors living in Southern Central Appalachia. We collected the stories of twenty-nine women cancer survivors from northeast Tennessee and southwest Virginia using a multi-phasic qualitative design. Phase I consisted of women cancer survivors participating in a day-long story circle (n=26). Phase II consisted of women cancer survivors who were unable to attend the story circle ; this sample sub-set participated in in-depth interviews (n=3) designed to capture their illness narratives. Participants\u27 illness narratives revealed the presence of: (1) mothering-disruption whereby cancer adversely impacted the mothering role ; and (2) mothering-connection , whereby the cancer experience motivatedmother-survivors. Participants\u27 illness narratives reflected thatthe role of mother was the preeminent role for mother-survivor and whenever there was oppositional tension between the roles of mother and survivor , the women-survivors seemed to linguistically relocate away from the survivor role and toward the mothering role. As a result , women-survivors seemingly rejected medicalization of their identities by emphasizing their mothering responsibilities , something we term motherizing
