In response to vandalism of the Ludlow memorial in 2003, members of this Commission and the Labor and Working-Class History Association (LAWCHA) strove to and succeeded in designating the Ludlow site as a National Historical Landmark. When one hears the phrase "Columbine Massacre", one may typically think of the school shooting from 1999 in Littleton, Colorado, where two students killed thirteen people and wounded twenty-one others before committing suicide.

The lattice constant, atomic relaxation and partial density of state of InxGa1-x As are calculated when composition x changes from 0 to 1. The results show that the changing regularity of lattice constant under in¬creased indium composition matches with Vegard theorem. When the system has been relaxed, the decrease degree of Ga--As bond will be larger with increased indium composition, and the decrease degree of In--As bond will not be changed. In addition, the calculation also found that the decrease degree of In--As--In bond angle will be very weak when the indium composition is more than 0.625. The Ga--As--Ga and Ga--As--Tn bond angles will be larger in different degrees, and the variation of Ga--As--Tn bond angle is the most serious when indium component is 0.5. The calculation results of partial density of state of system indicate that the physical properties of GaAs materials are seriously affected by the doped indium. [ABSTRACT FROM AUTHOR]

Throughout the 1970s and 1980s, commercialized reproductive technologies experienced a reputational crisis as news about the hormonal birth control pill's possible side effects reportedly caused 18-30% of women to stop taking it. While secondary literature has followed patients' and legislatures' actions, few histories have focused on physicians' responses. How did physicians manage this public crisis of confidence? This article contributes to existing literature through a backstage look at the work of Elizabeth B. Connell (1925-2018), whose wide-ranging career in medicine, academia, government, industry consulting, and popular writing embroiled her at the center of these controversies. To counter critique from legislatures and consumer reformers, Connell became a mediator for medicine in the public sphere, dispensing select information and arguing for limits on others - for the patient's sake. If legislative inquiry's primary havoc was unleashing information, Connell would help the profession moderate it. Because Connell was a woman doctor whom health feminists who were her contemporaries denied was a feminist doctor, the existing scholarship has occluded her. This article reconstructs the contributions of this important and flawed doctor, illuminating how she contorted herself to suit her various public messages, constrained by her conflicting, dual identities as woman and doctor., (© The Author(s) 2024.
