X-ray Variability and Emission Process of the Radio Jet in M87

We monitored the M87 jet with the ACIS-S detector on Chandra with 5 observations between 2002 Jan and 2002 Jul. Our goal was to determine the presence and degree of variability in morphology, intensity, and spectral parameters. We find strong variability of the core and HST-1, the knot lying 0.8" from the core. These observations were designed to constrain the X-ray emission process: whereas synchrotron emission would necessitate the presence of extremely high energy electrons with a halflife of a few years or less, inverse Compton emission from a relativistic jet would arise from low energy electrons with very long halflives. Currently, all indications point to a synchrotron process for the X-ray emission from the M87 jet. We give key parameters for a ``modest beaming'' synchrotron model.Comment: 4 pages with 2 embedded figures (1 in color).

Monomial principalization in the singular setting

We generalize an algorithm by Goward for principalization of monomial ideals in nonsingular varieties to work on any scheme of finite type over a field. The normal crossings condition considered by Goward is weakened to the condition that components of the generating divisors meet as complete intersections. This leads to a substantial generalization of the notion of monomial scheme; we call the resulting schemes `c.i. monomial'. We prove that c.i. monomial schemes in arbitrarily singular varieties can be principalized by a sequence of blow-ups at codimension 2 c.i. monomial centers.Comment: 7 pages, 2 figure

Reconnecting Our Youth, a Scan of Policy Opportunities to Improve Economic Success for Vulnerable Youth

In March 2012, Grad Nation campaign released its report on the progress of the nation's public schools in improving graduation rates and movement toward achieving the goal of a 4-year cohort graduation rate of 90 percent by 2020. It revealed that from 2001 to 2009, the graduation rate increased from 72 percent to 75 percent, an average of less than .5 percentage points a year. During that same period of time, nearly a half million young people dropped out of school annually. High school reform and graduation accountability efforts are critical to stemming the disconnection of youth from our public education system. However, until these innovations and reforms are imbedded at scale in our districts, we must pay commensurate attention to the needs of the millions of youth who are dropping out and falling outside of the education and labor market mainstreams

Teacher Educators under Surveillance at a Religious University

The purpose of this paper is to examine how institutional norms are enforced through surveillance and self-discipline among teacher educators at a religious university. The study builds on prior research regarding university norms and surveillance, as well as religious orientation and prejudice. Eight teacher educators met as part of a larger study on white racial identity and praxis. Focus groups and personal interviews were transcribed and analyzed using situational mapping, a postmodern form of grounded theory. Participants discussed four themes that illustrate surveillance and self-discipline: the university, academic culture, religion and whiteness, and sexism. The data reveal participant responses as highly structured by university norms about what one can and cannot say about particular topics. The results confirm the function of surveillance and norms in a university setting and illuminate the process in a religious context. Data reveal how fear played a part of the process, as participants disciplined themselves to fit university norms and censored themselves when they began to exercise agency

Diversity and the history curriculum: an action research approach to help trainee history teachers embrace cultural and ethnic diversity in the curriculum

This paper explores the issues that secondary history teachers on an Initial Teacher Education (ITE) programme in England encounter in attempting to incorporate more cultural and ethnic diversity into the history curriculum. It also assesses the impact that changes in their training course had on their views and pedagogical practice. Using questionnaires and scenario based interviews with three cohorts of trainee teachers, key challenges were identified, which were related to the purposes of teaching history and diversity, appropriate pedagogy and content, dealing with pupils, and teachers’ personal concerns. A framework for analysing trainees’ stances towards cultural and ethnic diversity based upon a confident-uncertain-uncomfortable continuum was developed. This operated within a socio-cultural framework that was identified and helps to explain the extent to which trainee history teachers were willing and able to embrace diversity within their teaching. The research revealed that the course had had an impact, although this was in subtle rather than marked ways, which raises further questions about what is possible within the confines of an ITE training programme and the need for additional support beyond the course

The Role and Work of Bomber Command: A Note by Air Marshal Sir Arthur Harris for the Prime Minister and Cabinet, 28 June 1942

Editor’s Note: Few senior Allied Commanders have been criticized as strongly as Air Marshal Sir Arthur Harris. And even those critics who recognize the vital contribution Harris and the Bomber Command made to the defeat of Nazi Germany are disturbed by the tone of Harris’ letters to Churchill and Air Chief Marshal Sir Charles Portal. Harris never wavered in his conviction that Germany could be defeated by strategic bombing with ground roops assigned to a secondary role. This view underlay his arguments for assigning priority to strategic bombing. In pursuing the case Harris mixed careful argument and clear logic with emotional attacks on those who doubted his doctrines. The following note, written shortly after Harris assumed command, displays Harris at his best, arguing the case for Bomber Command “as the only means of bringing assitance to Russian in time” and the only means “which will make subsequent invasion a possible proposition.
