This collection contains 139 correspondence from Maj. Bette J. Barto, USAFE to her parents while serving as a nurse during the late 1950s and 1960s. Also included are three photographs, one special orders document, and one marriage license. In several cases, Bette refers to her parents as Lizzie and Hugh Elmer, or simply Elmer. Three letters from 1961 or 1962 are undated and placed in a separate folder.https://digitalcommons.chapman.edu/bjbarto_correspondence/1057/thumbnail.jp

Inflation of Migrated Hot Jupiters
The observed low densities of gas giant planets with a high equilibrium
temperature can be simulated in models when a fraction of the surface radiation
is deposited deeper in the interior. Meanwhile migration theories suggest that
hot Jupiters formed further away from their host-star and migrated inward. We
incorporate disk migration in simulations of the evolving interior of hot
Jupiters to determine whether migration has a long lasting effect on the
inflation of planets. We quantify the difference between the radius of a
migrated planet and the radius of a planet that formed in situ as the radius
discrepancy. We remain agnostic about the physical mechanism behind interior
heating, but assume it scales with the received stellar flux by a certain
fraction. We find that the change in irradiation received from the host-star
while the planet is migrating can affect the inflation and final radius of the
planet. Models with a high fraction of energy deposited in the interior ( > 5%)
show a significant radius discrepancy when the deposit is at higher pressures
than P=1 bar. For a smaller fraction of 1%, there is no radius discrepancy for
any deposit depth. We show that a uniform heating mechanism can cause different
rates of inflation, depending on the migration history. If the forthcoming
observations on mean densities and atmospheres of gas giants give a better
indication of a potential heating mechanism, this could help to constrain the
prior migration of such planets.Comment: Accepted for publication in MNRA
Predictors of weight loss in young adults who are over-weight or obese and have psychosocial problems:a post hoc analysis
BACKGROUND: The aim of this study is in a general practice trial setting to identify predictive factors for weight loss after 1 year among young adults who are over-weight or obese and who have several psychosocial problems. METHODS: Twenty-eight general practitioners recruited 495 patients aged 20–45 years with psychosocial problems for a randomized general preventive study to increase self-efficacy to achieve a self-prioritised goal for a better life by discussions of resources and barriers for reaching the goal. The present study is a post hoc analysis of possible predictors of weight loss among all 218 patients who have over-weight or obesity. A 23-pages questionnaire was completed before and 1 year after randomization. 111 patients had a one-hour preventive health consultation with their general practitioners focused on life coaching and a follow-up consultation within 3 months, and 107 patients had no preventive consultation. RESULTS: Twenty-two patients stated during the preventive consultation that weight loss was a prioritised goal. They had a mean weight loss of 4.7 kgs compared with 1.6 kgs in the group without this goal and 1.6 kgs in the group without preventive consultation. In a logistic regression model, predictors of weight loss or no weight loss were a) pre-interventional consideration of weight loss within 30 days, b) having weight loss as a prioritised goal for improved quality of life, c) being female, d) being in the oldest half of participants, and e) having many psychosocial problems. In a linear regression model, the predictors together explained about 11 % of the weight loss. Important predictors were: obesity (explained 4 %), pre-interventional consideration of weight loss within 30 days (3 %), and having a preventive health consultation with weight loss as a prioritised goal (2 %). CONCLUSIONS: Pre-interventional consideration of weight loss within 30 days and having weight loss as a prioritised goal during the health consultation were two important predictors for weight loss. By structured interventions focussing on the patients’ priorities, self-chosen goals, their resources and barriers for reaching the goals, changes may be obtained; especially in participants with many problems who often do not accept participation in procedures on risks.
