Committees Tackle the Deficit

Summarizes the recommendations of a presidential commission and private bipartisan committee for reducing the federal deficit by cutting healthcare costs, Social Security outlays, and discretionary spending, and by raising taxes

Have Recent Budget Policies Contributed to Long-Run Fiscal Stability?

Examines developments in budget policies since January 2010; the president's 2011 budget, including economic stimulus and tax and spending policies; congressional action; and issues for health reform. Considers their effect on long-term sustainability

Controlling the Deficit: The Debate Continues

Looks at budget cuts proposed by House Republicans and the president's framework with respect to savings in healthcare spending, Social Security and other entitlement spending, and discretionary spending; tax policy; and the Budget Control Act

Downwash in Vortex Region Behind Rectangular Half-wing at Mach Number 1.91

Results of an experimental investigation to determine downwash and wake characteristics in region of trailing vortex system behind a rectangular half-wing at Mach number 1.91 are presented. The wing had a 5-percent thick symmetric diamond cross section beveled to a knife edge at the tip. At small angles of attack, downwash angles were in close agreement with predictions of linearized theory based on the assumption of an undistorted vortex sheet. At higher angles of attack, the flow was greatly influenced by the rolling up of the vortex sheet

Deweyan tools for inquiry and the epistemological context of critical pedagogy

This article develops the notion of resistance as articulated in the literature of critical pedagogy as being both culturally sponsored and cognitively manifested. To do so, the authors draw upon John Dewey\u27s conception of tools for inquiry. Dewey provides a way to conceptualize student resistance not as a form of willful disputation, but instead as a function of socialization into cultural models of thought that actively truncate inquiry. In other words, resistance can be construed as the cognitive and emotive dimensions of the ongoing failure of institutions to provide ideas that help individuals both recognize social problems and imagine possible solutions. Focusing on Dewey\u27s epistemological framework, specifically tools for inquiry, provides a way to grasp this problem. It also affords some innovative solutions; for instance, it helps conceive of possible links between the regular curriculum and the study of specific social justice issues, a relationship that is often under-examined. The aims of critical pedagogy depend upon students developing dexterity with the conceptual tools they use to make meaning of the evidence they confront; these are background skills that the regular curriculum can be made to serve even outside social justice-focused curricula. Furthermore, the article concludes that because such inquiry involves the exploration and potential revision of students\u27 world-ordering beliefs, developing flexibility in how one thinks may be better achieved within academic subjects and topics that are not so intimately connected to students\u27 current social lives, especially where students may be directly implicated

The Persistent Problem: Inequality, Difference, and the Challenge of Development

This report highlights the complex, multidimensional nature of inequality in the era of globalization. It documents that despite the impressive strides by nations like China and India, absolute inequality between the richest and poorest countries is greater than ever before in history. It demonstrates that the rise of China and India creates a new dimension to the persistent problem of inequality

Brokered Graph State Quantum Computing

We describe a procedure for graph state quantum computing that is tailored to fully exploit the physics of optically active multi-level systems. Leveraging ideas from the literature on distributed computation together with the recent work on probabilistic cluster state synthesis, our model assigns to each physical system two logical qubits: the broker and the client. Groups of brokers negotiate new graph state fragments via a probabilistic optical protocol. Completed fragments are mapped from broker to clients via a simple state transition and measurement. The clients, whose role is to store the nascent graph state long term, remain entirely insulated from failures during the brokerage. We describe an implementation in terms of NV-centres in diamond, where brokers and clients are very naturally embodied as electron and nuclear spins.Comment: 5 pages, 3 figure
