Folklore: in All of Us, in All We Do (open access)

Folklore: in All of Us, in All We Do

Compilation of articles about various topics related to folklore organized into five chapters by subject: "The first tackles this issue of folklore and its relationship to history, with some of the articles trying to provide some of that folkloric filler to historical facts. Another chapter focuses on women; one features various types of occupational lore; and another is a tongue-in-cheek look at 'shady characters' such as police officers, politicians, and horsetraders. A final chapter has no theme; it is a catch-all, containing a few interesting articles you may remember from some of our [Texas Folklore Society's] most recent meetings" (p. viii).

A Life on Paper: the Drawings and Lithographs of John Thomas Biggers

Access: Use of this item is restricted to the UNT Community
John Thomas Biggers (1924–2001) was a major African American artist who inspired countless others through his teaching, murals, paintings, and drawings. After receiving conventional art training at Hampton Institute and Pennsylvania State, he had his personal and artistic breakthrough in 1957 when he spent six months in the newly independent country of Ghana. From this time forward, he integrated African abstract elements with his rural Southern images to create a personal iconography. His new approach made him famous, as his personal discovery of African heritage fit in well with the growing U.S. civil rights movement. He is best known for his murals at Hampton University, Winston-Salem University, and Texas Southern, but the drawings and lithographs that lie behind the murals have received scant attention—until now. Theisen interviewed Dr. Biggers during the last thirteen years of his life, and was welcomed into his studio innumerable times. Together, they selected representative works for this volume, some of which have not been previously published for a general audience. After his death in 2001, his widow continued to work closely with Theisen, resulting in a book that is intimate and informative for both the scholar and the student.

Mexican Light: Healthy Cuisine for Today's Cook

Access: Use of this item is restricted to the UNT Community
Did you know that Pre-Columbian Mexican cuisine was low in fat and high in fiber and vitamins? Based on corn, squash, tomatoes, beans, and lean meats, the everyday diet of the first Americans was remarkably close to the recommendations for healthy eating we hear about every day. Now for the first time, cooks can use the secrets of the Aztecs in today’s kitchen, thanks to Kris Rudolph’s thoroughly researched cookbook. And because cooks from both sides of the border will be eager to try these recipes, Rudolph presents the recipes and text in Spanish on facing pages. The book opens with a short introduction outlining the history of Mexican cooking, followed by an overview of healthy eating habits, a description of the most common ingredients, and a useful guide to planning for parties. The fifty recipes cover everything from appetizers to after-dinner refreshers and each includes the number of calories, amounts of total fat and saturated fat, grams of carbohydrates, and amount of fiber. Rudolph suggests low-fat and low-carbohydrate alternatives, as well as ways to vary the spiciness.

Time-resolved THz studies of carrier dynamics in semiconductors, superconductors, and strongly-correlated electron materials (open access)

Time-resolved THz studies of carrier dynamics in semiconductors, superconductors, and strongly-correlated electron materials

Perhaps the most important aspect of contemporary condensed matter physics involves understanding strong Coulomb interactions between the large number of electrons in a solid. Electronic correlations lead to the emergence of new system properties, such as metal-insulator transitions, superconductivity, magneto-resistance, Bose-Einstein condensation, the formation of excitonic gases, or the integer and fractional Quantum Hall effects. The discovery of high-Tc superconductivity in particular was a watershed event, leading to dramatic experimental and theoretical advances in the field of correlated-electron systems. Such materials often exhibit competition between the charge, lattice, spin, and orbital degrees of freedom, whose cause-effect relationships are difficult to ascertain. Experimental insight into the properties of solids is traditionally obtained by time-averaged probes, which measure e.g., linear optical spectra, electrical conduction properties, or the occupied band structure in thermal equilibrium. Many novel physical properties arise from excitations out of the ground state into energetically higher states by thermal, optical, or electrical means. This leads to fundamental interactions between the system's constituents, such as electron-phonon and electron-electron interactions, which occur on ultrafast timescales. While these interactions underlie the physical properties of solids, they are often only indirectly inferred from time-averaged measurements. Time-resolved spectroscopy, consequently, is playing an ever increasing role …

THE ROLE OF DIELECTRIC CONTINUUM MODELS IN ELECTRON TRANSFER: THEORETICAL AND COMPUTATIONAL ASPECTS. (open access)

THE ROLE OF DIELECTRIC CONTINUUM MODELS IN ELECTRON TRANSFER: THEORETICAL AND COMPUTATIONAL ASPECTS.

Condensed phase physical and chemical processes generally involve interactions covering a wide range of distance scales, from short-range molecular interactions requiring orbital overlap to long-range coulombic interaction between local sites of excess charge (positive or negative monopoles). Intermediate-range distances pertain to higher-order multipolar as well as inductive and dispersion interactions. Efforts to model such condensed phase phenomena typically involve a multi-tiered strategy in which quantum mechanics is employed for full electronic structural characterization of a site of primary interest (e.g., a molecular solute or cluster), while more remote sites are treated at various classical limits (e.g., a molecular force field for discrete solvent molecules or a dielectric continuum (DC) model, if the solute is charged or has permanent multipole moments). In particular, DC models have been immensely valuable in modeling chemical reactivity and spectroscopy in media of variable polarity. Simple DC models account qualitatively for many important trends in the solvent dependence of reaction free energies, activation free energies, and optical excitation energies, and many results of semiquantitative or fully quantitative significance in comparison with experiment have been obtained, especially when detailed quantum chemical treatment of the solute is combined self consistently with DC treatment of the solvent (e.g., as …

SPIN POLARIZED PHOTOELECTRON SPECTROSCOPY AS A PROBE OF MAGNETIC SYSTEMS. (open access)

SPIN POLARIZED PHOTOELECTRON SPECTROSCOPY AS A PROBE OF MAGNETIC SYSTEMS.

Spin-polarized photoelectron spectroscopy has developed into a versatile tool for the study of surface and thin film magnetism. In this chapter, we examine the methodology of the technique and its recent application to a number of different problems. We first examine the photoemission process itself followed by a detailed review of spin-polarization measurement techniques and the related experimental requirements. We review studies of spin polarized surface states, interface states and quantum well states followed by studies of the technologically important oxide systems including half-metallic transition metal oxides, ferromagnet/oxide interfaces and the antiferromagnetic cuprates that exhibit high Tc Superconductivity. We also discuss the application of high-resolution photoemission with spin resolving capabilities to the study of spin dependent self energy effects.
