Resonant Processes in a Frozen Gas

We present a theory of resonant processes in a frozen gas of atoms interacting via dipole-dipole potentials that vary as $r^{-3}$, where $r$ is the interatomic separation. We supply an exact result for a single atom in a given state interacting resonantly with a random gas of atoms in a different state. The time development of the transition process is calculated both on- and off-resonance, and the linewidth with respect to detuning is obtained as a function of time $t$. We introduce a random spin Hamiltonian to model a dense system of resonators and show how it reduces to the previous model in the limit of a sparse system. We derive approximate equations for the average effective spin, and we use them to model the behavior seen in the experiments of Anderson et al. and Lowell et al. The approach to equilibrium is found to be proportional to $\exp (-\sqrt{\gamma_{eq}t}$), where the constant $\gamma _{eq}$ is explicitly related to the system's parameters.Comment: 30 pages, 6 figure

New-to-the-School Teachers\u27 Responses to Evaluation Policy

When teachers are new to a school, they must make sense of policies within a new context. In this horizontal comparative case study, I analyze interview data from three teachers in North Carolina taken at two points in a school year to explore how new teachers make sense of and respond to teacher evaluation policy. Study participants framed the evaluation problem around the extent to which school-level enactment focused on assessment. Teachers demonstrated the following reform typologies in response to their sensemaking around evaluation policy: Assimilation, Adaptation, and Avoidance. When new to a school, teachers are expected to follow the same policies and processes as teachers who have long operated in that school\u27s policy context. So, new-to-the-school teachers must reconcile new-to-them policies with their personal preconceptions of practice in an entirely new context. Teacher evaluation policies outline what is valued in teaching by delineating and measuring those values. So, it is worth considering how teacher perceptions of evaluation may influence their practice and career choices, particularly teachers trying to balance such valuation with their daily work in an unfamiliar context. This case study of three teachers in North Carolina utilizes sensemaking theory and problem framing to explore the question, how do teachers who are new to a school make sense of and respond to teacher evaluation policy

Predicting Progression in Parkinson's Disease Using Baseline and 1-Year Change Measures.

BackgroundImproved prediction of Parkinson's disease (PD) progression is needed to support clinical decision-making and to accelerate research trials.ObjectivesTo examine whether baseline measures and their 1-year change predict longer-term progression in early PD.MethodsParkinson's Progression Markers Initiative study data were used. Participants had disease duration ≤2 years, abnormal dopamine transporter (DAT) imaging, and were untreated with PD medications. Baseline and 1-year change in clinical, cerebrospinal fluid (CSF), and imaging measures were evaluated as candidate predictors of longer-term (up to 5 years) change in Movement Disorders Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) score and DAT specific binding ratios (SBR) using linear mixed-effects models.ResultsAmong 413 PD participants, median follow-up was 5 years. Change in MDS-UPDRS from year-2 to last follow-up was associated with disease duration (β= 0.351; 95% CI = 0.146, 0.555), male gender (β= 3.090; 95% CI = 0.310, 5.869), and baseline (β= -0.199; 95% CI = -0.315, -0.082) and 1-year change (β= 0.540; 95% CI = 0.423, 0.658) in MDS-UPDRS; predictors in the model accounted for 17.6% of the variance in outcome. Predictors of percent change in mean SBR from year-2 to last follow-up included baseline rapid eye movement sleep behavior disorder score (β= -0.6229; 95% CI = -1.2910, 0.0452), baseline (β= 7.232; 95% CI = 2.268, 12.195) and 1-year change (β= 45.918; 95% CI = 35.994,55.843) in mean striatum SBR, and 1-year change in autonomic symptom score (β= -0.325;95% CI = -0.695, 0.045); predictors in the model accounted for 44.1% of the variance.ConclusionsBaseline clinical, CSF, and imaging measures in early PD predicted change in MDS-UPDRS and dopamine-transporter binding, but the predictive value of the models was low. Adding the short-term change of possible predictors improved the predictive value, especially for modeling change in dopamine-transporter binding

Women’s Advocate or Racist Hypocrite: Gertrud Scholtz-Klink and the Contradictions of Women in Nazi Ideology

The Reichsfrauenführerin, Gertrud Scholtz-Klink, led the National Socialist Women’s League from 1934 until she went into hiding in 1945. During her career in the Nazi Party, she created a female focused sector of the party that promoted pronatalist propaganda, discouraged women from engaging in politics, and urged women to only perform gender-suitable work. In contradiction to her message, Scholtz-Klink was the highest-ranking female political figure and a divorcee, who regularly chose her political career with the Nazi Party over her duties in the private sphere. Although she had little to no political power in the inner circle because of her sex, she did influence the actions and ideals of German women. She retrospectively claimed women, including herself, were not political. However, her speeches and other retrospective statements of hers demonstrated the racist ideology she promulgated for the party. This demonstrated Scholtz-Klink’s complicity in the atrocities perpetrated by the Nazis against the Jews and non-Germans. Nazi ideology of women was contradictory and always evolving because the Nazis’ main focus was the annihilation of the Jews, not control over women. Because of generations of systemic misogyny and racism, women posed no perceived threat to the Nazi men. Therefore, female focused policies lacked stability since “racial purification” was the first priority of the Nazi Regime

‘Together … for only a moment’ British newspaper constructions of altruistic non-commercial surrogate motherhood

Objectives: To explore how national altruistic surrogacy is framed in a representative selection of the British press. Methods: A study of 90 British national newspaper articles was carried out using the Lexis-Nexis data base to search for articles on altruistic surrogacy. Content analysis of gain, loss, neutral frames and high or low alarm and vulnerability frames in the titles and the body of the text was carried out. The type of construction used in the article content was also analysed. Data were coded and consensus reached using a coding strategy specifically developed for the purposes of this study. Results: Titles and content were predominantly loss, high alarm and high vulnerability framed. The content was also gain framed, and written with a focus on the social and legal aspects differentially between the newspaper types. Discussion: The tabloid press emphasizes social issues, and the middle market and serious press focus on legal issues of altruistic surrogacy. Selectively framed and reinforced information provided by the different newspapers, reflect the different readership, with Tabloid readers likely to be, surrogates (mostly from lower socioeconomic strata) and serious/ middle-market readers likely to be commissioning parents (mostly professionals)

[Job] Locked and [Un]loaded: The Effect of the Affordable Care Act Dependency Mandate on Reenlistment in the U.S. Army

One concern with employer-based health insurance is job lock or the inability for employees to leave their current employment for better opportunities for fear of losing benefits. We use the implementation of the Affordable Care Act’s dependency mandate as a natural experiment. Data from the United States Army overcome some limitations in previous studies including the ability to examine workers with fixed contract expiration dates, uniform pay, and health coverage. We find that the ACA decreased reenlistment rates by 3.13 percent for enlisted soldiers aged 23–25. We also find that younger veterans who leave the army are more likely to attend college. These findings show that the ACA reduced job lock and increased college-going
