The letters of Charlotte Mary Yonge (1823-1901) edited by Charlotte Mitchell, Ellen Jordan and Helen Schinske.

Charlotte Yonge is one of the most influential and important of Victorian women writers; but study of her work has been handicapped by a tendency to patronise both her and her writing, by the vast number of her publications and by a shortage of information about her professional career. Scholars have had to depend mainly on the work of her first biographer, a loyal disciple, a situation which has long been felt to be unsatisfactory. We hope that this edition of her correspondence will provide for the first time a substantial foundation of facts for the study of her fiction, her historical and educational writing and her journalism, and help to illuminate her biography and also her significance in the cultural and religious history of the Victorian age

Adam Smith Meets an Index of Specialization in International Trade

Development economists agree that increasing export diversification is a concomitant to economic development. An accepted explanation for Africa’s export stagnation is its dependence on monoculture, and on small number of commodities. Recently a large body of literature focuses on the relationship between economic growth and export specialization. However, there does not exist one generally acceptable measure or index for the concept of “Specialization in International Trade”. This paper suggest one such measure for specialization and its theoretical and conceptual framework are developed and applied to Singapore, South Korea, Malaysia, Mexico, Tunisia and Morocco, during the years of their take offs.Trade Specialization Indices; Development Theory; Developing Country Export Compositions; International Trade Theory; Trade in Manufactures; Trade and Transformation.

The Ability to Adapt and Overcome Obstacles: Machinery Exports of Poland

From 1980-2009 the Polish economy experienced structural dislocation. The growth and success of the Solidarity movement represented the shift in manufacturing from Soviet bloc trade to membership in the European Union. This paper examines four independent metrics that measure the changing “sophistication” of trade patterns during this modal shift. The common theme underlying the analysis of these indices is that the Polish economy is resilient and adaptable. Poland is expected to compete effectively in its new economic environment after a period of adjustment and progress.Trade Patterns in a Transition Economy, Machinery and Transport Equipment, Exports, Poland, Solidarity, Structural Change, Sophistication Indices, Trade Specialization Index, Intra-Industry Trade, Shock Therapy, Revealed Comparative Advantage, Herfendahl-Hirschman Index, Standard International Trade Classification, Compositional Shifts, Data Aggregation, Dispersion; Market Power

Testing of UH-60A helicopter transmission in NASA Lewis 2240-kW (3000-hp) facility

The U.S. Army's UH-60A Black Hawk 2240-kW (3000-hp) class, twin-engine helicopter transmission was tested at the NASA Lewis Research Center. The vibration and efficiency test results will be used to enhance the data base for similar-class helicopters. Most of the data were obtained for a matrix of test conditions of 50 to 100 percent of rated rotor speed and 20 to 100 percent of rated input power. The transmission's mechanical efficiency at 100 percent of rated power was 97.3 and 97.5 percent with its inlet oil maintained at 355 and 372 K (180 and 210 F), respectively. The highest vibration reading was 72 g's rms at the upper housing side wall. Other vibration levels measured near the gear meshes are reported

Probing the structure of entanglement with entanglement moments

We introduce and define a set of functions on pure bipartite states called entanglement moments. Usual entanglement measures tell you if two systems are entangled, while entanglement moments tell you both if and how two systems are entangled. They are defined with respect to a measurement basis in one system (e.g., a measuring device), and output numbers describing how a system (e.g., a qubit) is entangled with that measurement basis. The moments utilize different distance measures on the Hilbert space of the measured system, and can be generalized to any N-dimensional Hilbert space. As an application, they can distinguish between projective and non-projective measurements. As a particular example, we take the Rabi model's eigenstates and calculate the entanglement moments as well as the full distribution of entanglement.Comment: 5 pages, 5 figure
