Does the scatterometer see wind speed or friction velocity?

Studies of radar backscatter from the sea surface are referred either to the wind speed, U, or friction velocity, u(sub *). Bragg scattering theory suggests that these variations in backscatter are directly related to the height of the capillary-gravity waves modulated by the larger waves in tilt and by straining of the short wave field. The question then arises as to what characteristic of the wind field is most probably correlated with the wave number spectrum of the capillary-gravity waves. The justification for selecting U as the appropriate meteorological parameter to be associated with backscatter from L-band to Ku-band are reviewed. Both theoretical reasons and experimental evidence are used to demonstrate that the dominant parameter is U/C(lambda) where U is the wind speed at a height of about lambda/2 for waves having a phase speed of C(lambda)

Renormalization Group Study of the Intrinsic Finite Size Effect in 2D Superconductors

Vortices in a thin-film superconductor interact logarithmically out to a distance on the order of the two-dimensional (2D) magnetic penetration depth $\lambda_\perp$, at which point the interaction approaches a constant. Thus, because of the finite $\lambda_\perp$, the system exhibits what amounts to an {\it intrinsic} finite size effect. It is not described by the 2D Coulomb gas but rather by the 2D Yukawa gas (2DYG). To study the critical behavior of the 2DYG, we map the 2DYG to the massive sine-Gordon model and then perform a renormalization group study to derive the recursion relations and to verify that $\lambda_\perp$ is a relevant parameter. We solve the recursion relations to study important physical quantities for this system including the renormalized stiffness constant and the correlation length. We also address the effect of current on this system to explain why finite size effects are not more prevalent in experiments given that the 2D magnetic penetration depth is a relevant parameter.Comment: 8 pages inRevTex, 5 embedded EPS figure

A Study of the Reasons Forty Non-Black Students Chose to attend Omaha Technical High School for the 1975-1976 School Year

Omaha Technical High School is one of eight senior high schools in the Omaha Public School system. Historically, Technical High School is a comprehensive public high school. College preparatory and vocational courses are offered at the school. In the early 1960\u27s special education classes for the educable mentally retarded were started at Technical High School. This program was the only special education program in the Omaha Public Schools system at the high school level

Exploring Familiar Landscapes: The Importance of the Local In Lower Mississippi Valley Community-Based Archaeology

This thesis explores the community-based projects that the Smith Creek Archaeological Project has implemented in Wilkinson County, Mississippi, as well and its goals for future community-oriented work by expanding on current methodology and archaeological theory. I deal mainly with the problems of identifying and inspiring local stakeholders to be future stewards of sites in a region marred by the violence of the colonial encounter, which left few local descendant populations. I argue that combining certain aspects of archaeological theory with community archaeology methodology can create an engaged community of stakeholders that are connected to the past through a shared, familar landscape. I contend that locally engaged and locally collaborative work aimed at connecting local populations with past populations through emphasizing the shared lifeways and landscapes that are part and parcel of their quotidian lives is key to protecting sites and engendering respect for past and present Native communities. People feel more connected and comfortable with different cultures and groups when they feel like they share in similar lifeways. For that reason, identifying lifeways and landscapes that overlap in time and space can make people feel more comfortable with the different groups and cultures that have inhabited the land before them and encourage them to protect it for those who come after. By building upon the archaeological theory of persistence and combining it with methodologies used in community archaeology, I suggest that communities can be inspired to care about and preserve cultural heritage that may not be their own by experiencing the similarities and connections they have to shared lifeways and place

The role of identity moderators and perceived degree of identity separation in librarian professional identity development

This paper examines in-depth processes of librarian professional identity negotiations impacting practitioners’ perception of, affiliation with, and behaviour within the profession. It outlines three key themes which moderate librarian professional identity and introduces the Relational States of Librarian Professional Identity, outlining variations of individual affiliation with the profession. This paper also offers a theoretical framework of identity negotiations with theoretical propositions relating to librarian professional identity development. Forty semi-structed interviews were conducted with practicing public librarians throughout Aotearoa New Zealand. Interviews were analysed with an inductive approach. NVivo was used to code and query interview data. Findings demonstrate identity negotiations as grounded in perceptions of profession through meaning ascribed to the profession and its manifestations (professional associations, etc.), respectively; and perceptions of practice as related to organisational/institutional contexts. Six theoretical propositions are offered detailing the relationship of the three themes moderating librarian professional identity and the Relational States of Librarian Professional Identity to this identity and its negotiations

The critical incident negotiation process of public librarians in Aotearoa New Zealand

This paper reports findings from interviews with practicing public librarians in Aotearoa New Zealand. It details respondent understanding of influences on perception and behaviour, and critical incidents as they relate to librarian professional identity. In-depth semi-structed interviews were conducted with forty practicing public librarians. Interviews were analysed with an inductive approach. Findings report on sample tendencies of dominant influences on practitioners' perception and behaviour, impacting professional identity development over time. Dominant influences are respondent understanding of the strongest aspect they understand to influence their professional identity for both their individual perception of their professional identity and social factors influencing their professional behaviour. Findings also report on the identity negotiation process prompted by critical incidents, whose criticality is reliant on individual perception of incident in relation to professional identity. This process outlines affective response to the critical incident as a gateway to identity negotiations, leading to a discovery and/or growth of an identity facet, which will either affirm or undermine identity understanding. This process may be iterative, as meaning ascribed to the incident may change over time. Three theoretical propositions are presented articulating the role of dominant influences and critical incidents on identity negotiations of public librarian professional identity

Functional near-infrared spectroscopy for Hb and HbO₂ detection using remote sensing

The goal of the work presented in this thesis is to develop a wireless, near-infrared (NIR) imaging system to provide flexibility and functionality to clinicians and researchers who require monitoring of blood profusion to tissue, muscles, or the brain. The prototype device uses a single stimulus/detection unit composed of an Epitex NIR LED with three wavelength options: 730, 805, and 850 nm, and an OPT101 photodiode detector. The device can be used to detect changes in the levels of oxygenated and deoxygenated hemoglobin in the body by measuring the amounts of absorbed and backscattered light at the wavelength associated with the correct compound. The backscattered light collected by the optical sensor is converted to a digital, serial bit stream for wireless transmission to a base station computer. The usefulness of this design may significantly change the way in which researchers and clinicians study the human body. Without the need to attach a subject to bulky equipment and confine them to a laboratory setting, the investigator can gather data unrestricted by the experimental setting. This advantage permits a vital metabolic indicator to be studied in many different and extremely difficult situations
