A219, 89 (1953).Author Institution: Space Physics Laboratory, Aerospace Corporation“The absorption of ultraviolet radiation by sodium vapor, and the associated ionization, has been investigated from 1040{\AA} to 3500{\AA} using a two-metre McPherson normal incidence spectrometer and an absorption chamfer of the type described by Ditchburn and The atomic cross section at the series limit (2412 {\AA}) was found to be , in good agreement with the previous result obtained by Ditchburn, Jutsum and The atomic cross section decreases to a minimum at 1900{\AA} and then increases again towards shorter wavelengths. Continuous molecular absorption was observed from 3500{\AA} to 1700{\AA} and ion chamber measurement indicate that this absorption is due to an ionization continuum. Ion current peaks were also seen between 2413{\AA} and 3500{\AA} at wavelengths corresponding to the series absorption lines of the sodium atom. Curves will be presented showing the variation with wavelength of both the atomic cross section and the relative molecular cross section.
Polyphony and the anxiety of influence in the fiction of Henry James
No full textJames's fiction, especially in the Middle Phase, centres
on the figure of the artist and is characterized by, the two
interrelated aspects which previous criticism has largely
overlooked: the Bakhtinian 'polyphonic' -creation of
'author-thinkers'; and the conflict between ephebes and
precursors, for which Harold-Bloom's concept of 'the-anxiety of
influence' is the most illuminating model. Polyphony is the
narrative mode, and influence is the intra-artistic, theme.
These, as the Introduction to the thesis makes clear, are
rehearsed in James's inaugural novel, Roderick Hudson. Rowland
Mallet is an author-thinker, and his failure is caused by
authorial limitations. His monologism -is impaired by his
mistaking empathy for the authorial sympathy. Likewise,
Hudson's failure does not arise from a mercurial temperament,
but from a polyphonic shortcoming: not possessing the power of
fiction to contain the fiction of power in, his mentor. And the
relationships among the three artists - Gloriani, Hudson and
Singleton - perfectly exemplify the Bloomian-theme. It is these
two concepts, polyphony and influence, which are the major
preoccupation in the Middle Phase; as, the works chosen
demonstrate. These are a novella, a novel, and a number of
short stories all of which have been unjustifiably neglected.
Chapter One, on The Aspern Papers, argues that Tina Bordereau,
far from being, the artless victim seen by many critics,
actually challenges and defeats the narrator by the very form
of her narrative. Her 'realist' discourse undermines his
language of 'romance', and shows up its internal unstability.
Chapter Two is an extensive study of the critical reception of
The Tragic Muse. The most common areas of critical attention
have been its contemporary topicality, its relation to previous
novels on similar themes, and the possible genealogy of Gabriel
Nash. Those have all missed the core of the work. - Chapter Three
demonstrates how polyphony and the anxiety of influence make
the novel what it really is. Influence arises from the
juxtaposition of, and the wrestling between, artistic ephebes
and their precursors (Nick and Nash,, Miriam and Madame Carre).
The dialogic quality defined by Bakhtin is crucial to the
proper, and even-handed, characterization of all, the conflicts
in the novel. And since most of James's tales in the eighties
and nineties -are about 'masters - and acolytes, the anxiety of
influence remains central. Chapter Four is a study of 'The
Author of Beltraffiol' and 'The Lesson of the Master'. Again the
characters' manipulations are a crucial focus in a way that
G6rard Genette's terminology helps to illuminate. The fact that
the ephebe is the author-thinker emphasizes the inextricability
of the Bakhtinian and the Bloomian in James. Just as
polyphony offers a different focus for explicating the poetics
of James's fiction; so the ephebal conflict provides the basis
for a fresh perception of James's own artistic struggle
Cultural Complexity, Post-Colonialism and Educational Change: Challenges for Comparative Educators
No full textThis paper is based on the presidential address given by the author at the 12th Congress of the World Council of Comparative Education Societies (WCCES) in Havana, October 2004. The study explores various elements in the struggle for a postcolonial refashioning of cultural identity through education. Drawing on experiences in Australia and the Caribbean, the author illustrates how educational systems undergoing decolonisation reflect socio-cultural tensions of race and power. She discusses the complexities for comparative educations in engaging with suppressed knowledge, recognising the yearnings of the marginalised, challenging the conditions that lead to poverty, and refashioning education for social justice in an era when the achievement of justice seems increasingly difficult. She argues that comparative educators can benefit from using postcolonial thinking to understand cultural complexity and promote life-affirming practices in educational change
Comprehensive water resources management : a concept paper
No full textThe world is entering a period of intense competition for limited supplies of water for alternative uses - in agriculture, in urban and industrial supplies, for recreation, by wildlife, for human consumption, and to maintain environmental quality. Manifestations of this competition and our current ability to deal with it can be observed in many parts of the world. A large irrigation project in India does not operate because water has been diverted to the rapidly growing city of Pune. In China, industries are reducing their production because of water shortages. In California, selenium salts leached by irrigation are killing wildlife. Bank irrigation projects in Algeria are now competing with Bank urban water supply projects for the same water. Many proposed irrigation projects and most hydro project proposals are on hold because of environmental concerns. Until recently, the approaches taken in water planning management by planners in the developing countries and by analysts at the funding agencies were, by and large, appropriate and adequate to the task at hand. The increased competition for water, however, makes most of the project-by-project planning methods inadequate. The author discusses new approaches that are needed to integrate water resource use among different users and across different economic sectors.Water and Industry,Water Conservation,Environmental Economics&Policies,Town Water Supply and Sanitation,Water Supply and Sanitation Governance and Institutions
Design metrics for evaluating the propulsive efficiency of future ships
No full textThere is an increasing need for the ship design process to take account of environmental issues such as the emission of greenhouse gases and the likely extension of a carbon dioxide charging mechanism to international shipping. These issues, together with the need for economic viability, provide further incentives to improve the efficiency of propulsion of ships. The main components of powering are firstly reviewed. Individual components and other power saving devices are identified which should contribute to improvements in the overall efficiency of propulsion. Suitable design metrics and procedures, taking into account economic and environmental factors, are recommended for the design of future ships
The Benefits of Being Economics Professor A (and not Z)
No full textAlphabetic name ordering on multi-authored academic papers, which is the convention in the economics discipline and various other disciplines, is to the advantage of people whose last name initials are placed early in the alphabet. As it turns out, Professor A, who has been a first author more often than Professor Z, will have published more articles and experienced afaster growth rate over the course of her career as a result of reputation and visibility. Moreover, authors know that name ordering matters and indeed take ordering seriously: Several characteristics of an author group composition determine the decision to deviate from the default alphabetic name order to a significant extent.performance measurement, incentives, economists, name ordering
The impact of attachment anxiety on susceptibility to false memories
No full textPrevious research shows that people's attachment styles predict memory functioning. For example, people with relatively insecure attachment styles tend to forget relationship-relevant information, as well as negatively bias their emotional evaluations of interpersonal experiences over time. An emerging body of research has also begun to suggest that attachment anxiety in particular relates to people's propensity to experience false memories. The present dissertation describes two randomized experiments which attempted to examine a causal link between attachment anxiety and false memories. Furthermore, the present studies attempted to isolate whether attachment anxiety causes false memories during memory maintenance or retrieval processes.
Participants were primed with either (1) high attachment anxiety, (2) low attachment anxiety, or (3) were not primed prior to retrieval (Study 1) or during maintenance (Study 2). The experimental primes had no main effects on false memories in either study. This may indicate that attachment anxiety does not cause false memories during maintenance or reconstruction. However, future research should explore whether attachment anxiety might cause false memories during encoding processes. Alternatively, it may be the case that the priming paradigms used failed to appropriately manipulate participants' attachment security, which would render the present findings ambiguous. Current procedures for priming attachment security and future directions for studying links between attachment anxiety and false memories are discussed.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-05-01The student, Nathan Hudson, accepted the attached license on 2016-02-01 at 08:56.The student, Nathan Hudson, submitted this Dissertation for approval on 2016-02-01 at 09:04.This Dissertation was approved for publication on 2016-02-02 at 10:58.DSpace SAF Submission Ingestion Package generated from Vireo submission #9057 on 2016-07-07 at 14:16:01Made available in DSpace on 2016-07-07T21:04:21Z (GMT).

The influence of African sculpture on British art, 1910-1930
No full textThis thesis aims to discuss the influence of African wood sculpture
on British art from 1910 to 1930. It proposes that the works, tastes and
pronouncements of various 20th century British artists betray this
influence and that although the British artists did not initially
understand the conceptual foundations of African sculpture their limited
knowledge was just sufficient for the modernization of British art
through the adaptation of the formal qualities of African art.
In assessing the validity of these propositions the thesis examines
the factors and issues that facilitated the influence. Chapter 1
discusses the formal qualities of African wood sculpture that attracted
the British artists. It outlines the unusual figural proportions, the
free and direct use of planar, linear and solid geometry, the treatment
of material and its surfaces.
The conceptual foundations of African sculpture are generally
outlined in Chapter 2. The extent to which the British artists
understood these foundations is also discussed.
Chapter 3 concerns the introduction of African sculpture to Britain
and discusses the development of the anthropological and subsequent
aesthetic interest that it aroused. Both the Post-Impressionist
Exhibitions and the Omega Workshops which facilitated its influence are
examined. Chapter 4 examines the concept and attempts to categorize the
nature of this influence.
The last three chapters act as case studies in which the impact of
African sculpture on Epstein, Gaudier-Brzeska and Henry Moore is
examined. The conclusion discusses the term 'Primitive' and the British
artists and the 'Primitive

Increasing the solvent polarizability decreases the energy gap leading to increased mixing. Extension of a relation between radiative lifetime and absorption permits an estimate of the energy gap between the states and the magnitude of the mixing matrix element
