Method of and means for testing a glancing-incidence mirror system of an X-ray telescope

An apparatus was designed for measuring the resolution and efficiency of a glancing-incidence mirror system having an even number of coaxial and confocal reflecting surfaces for use in an X-ray telescope. A collimated beam of X-rays is generated by an X-ray laser and directed along the axis of the system so that the beam is incident on the reflecting surfaces and illuminates a predetermined area. An X-ray detector, such as a photographic film, is located at the common focus of the surfaces so that the image produced by the X-rays may be compared with a test pattern interposed between the laser and the system

The drill down

textThe town of Millerton, Pa., has always been a small, rural farming community. Settled atop of the famed Marcellus Shale in the foothills of the Appalachians, there have always been rumors of natural gas in the hills around town. In 2008, natural gas companies arrived and began drilling. For a select few lucky enough to have property around the gas wells, their arrival means big money. But not all residents will get so lucky. For many folks in Millerton, the arrival of the gas companies means more traffic, more pollution, more crime and more inconvenience without a monthly royalty check to buffer the pain. The sheer amount of natural gas scientists predict is in the Marcellus Shale will forever change how the U.S. and the rest of the world use energy. Politicians tout it as liberation from foreign oil. Scientists see it as an alternative to “dirty” coal. For this small town, natural gas means change. The money the natural gas companies are pumping into this local economy will change the lives of the townsfolk- and the town itself- forever.Journalis

Open Access Challenge

This class activity is designed to help health sciences students understand challenges to accessing public health information in a variety of settings. The exercise was created for students in Prof. Dailey’s Global Health class (HS 322) at Gettysburg College in Fall 2015. The activity, as well as notes for instructors considering using this exercise, are both shared here

A change of rings result for Matlis reflexivity

Let $R$ be a commutative Noetherian ring and $E$ the minimal injective cogenerator of the category of $R$-modules. An $R$-module $M$ is (Matlis) reflexive if the natural evaluation map $M \to \operatorname{Hom}_R(\operatorname{Hom}_R(M,E),E)$ is an isomorphism. We prove that if $S$ is a multiplicatively closed subset of $R$ and $M$ is a reflexive $R$-module, then $M$ is a reflexive $R_S$-module. The converse holds when $S$ is the complement of the union of finitely many minimal primes of $R$, but fails in general

Building scale in community impact investing through nonfinancial performance measurement

The measurement of nonfinancial performance is becoming increasingly important in the community impact investing industry, where individuals and institutions actively deploy capital in low-income domestic markets for both financial and social returns. Quality data ensure that the creation of jobs, construction of community facilities, financing of affordable housing, and other benefits that characterize the sector are delivered cost-effectively and transparently. This paper discusses the limited practice and future direction of nonfinancial performance measurement by revisiting four key questions: ; 1. Does nonfinancial performance measurement really matter for investors? ; 2. If it does matter, is nonfinancial performance measurement even possible? ; 3. If nonfinancial performance is possible to measure, what form should it take? ; 4. How will nonfinancial performance measurement increase community impact investing? ; The paper examines the barriers to a more robust regime of nonfinancial performance measurement and posits both that innovation in the sector ought to be driven by the discrete but explicit needs and demands of investors, and that greater accountability has a special role to play in making disclosure more attractive. The report concludes that nonfinancial performance measurement directly informs the investment process and is essential to growing community impact investing because it provides latent sources of capital with market-level information on the tradeoffs between financial and social return. Although the industry is unlikely to discover the “silver bullet” of nonfinancial performance measurement in the near future, there is reason to be hopeful: measurement strategies can – and will – converge through private- and public-sector innovation.Community development

STEMteach: Preparing the Next Generation of Mathematics and Science Teachers

With an increasing demand for individuals prepared in Science, Technology, Engineering, and Mathematics (STEM), one university responded to this call by changing its teacher preparation program. Better-prepared mathematics and science teachers have the opportunity to engage and excite students, thereby preparing and promoting more of them to enter the STEM professions. The described program is a replication of the national UTeach model that recruits content majors in mathematics and science to explore the teaching profession during a first-semester course that includes an early field experience in the elementary grades. This field experience is designed to be engaging for both the teacher education candidates and the elementary students in an effort to demonstrate the joy of teaching and to retain the candidates in the program. The ultimate goal of the program is to increase the production of quality secondary mathematics and science teachers who can transfer their own deep understanding of their content to students so that these students will be career and college ready in the STEM disciplines
