The Incest Taboo in Wuthering Heights : A Modern Appraisal

Description: A modern interpretation of Wuthering Heights suggests that an unconscious incest taboo impeded Catherine and her foster brother, Heathcliff, from achieving normal sexual union and led them to seek union after death. Insights from anthropology, psychology, and sociology provide a key to many of the subtleties of the novel by broadening our perspectives on the causes of incest, its manifestations, and its consequences. Anthropology links the incest taboo to primitive systems of totemism and rules… more

Expulsion of Carriers from the Double-Barrier Quantum Well and Investigation of Its Spectral and Transport Consequences

Description: In this work I investigate the expulsion of carriers from nanostructures using the double-barrier quantum well (DBQW) as an example and discuss manifestations of this effect in the spectrum of the DBQW in absence of bias, and in the tunneling current in presence of bias. Assuming equality of the Fermi energy in all regions of the considered system, I compute the relative density of carriers localized in the DBQW and conclude that a fraction of carriers is expelled from this nanostructure.

L-Shell X-Ray Production Cross Sections for ₂₀Ca, ₂₆Fe, ₂₈Ni, ₂₉Cu, ₃₀Zn, ₃₁Ga, and ₃₂Ge by Hydrogen, Helium, and Lithium Ions

Description: L-shell x-ray production cross sections are presented for Fe, Ni, Cu, Zn, Ga, and Ge by 0.5- to 5.0-MeV protons and by 0.5- to 8.0-MeV helium ions and Ca, Fe, Ni, Cu, and Ge by 0.75- to 4.5-MeV lithium ions. These measurements are compared to the first Born theory and the perturbed-stationary- state theory with energy-loss, Coulomb deflection, and relativistic corrections (ECPSSR). The results are also compared to previous experimental investigations. The high precision x-ray measurements were … more

Naloxone Potentiation of Epinephrine Induced Vasoconstriction in Canine Skeletal Muscle Arteries

Description: Naloxone (NX) potentiated epinephrine (EPI) induced submaximal vasoconstriction in canine renal and skeletal muscle arterial segments, yet had no vasoconstrictor action alone. Developed tension generated in-vitro by 4 x 1mm. O.D. rings from 1st degree branches of canine femoral arteries was expressed as % of KCI induced maximum response. NX (10^-5 M) potentiated EPI induced submaximal contractions (34.2%) significantly more than contractions induced by norepinephrine, phenylephrine, lofexidine,… more

Locational Determinants of Real Estate Valuation: an Analysis of Spatial Autocorrelation in the Hedonic Pricing of Real Estate

Description: Recent studies of the valuation of real estate have concentrated on the use of hedonic pricing techniques in which the implicit prices of the component characteristics of an asset are inferred from the observed sale price using regression analysis. All of these studies include as explanatory variables one or more locational factors, such as distance to the central business district, as proxies for the effect that location has on the utility of land. In this research, the explicit consideration … more

Construct Use and Self-Aspect Change in Recovery From Coronary Artery Bypass Graft Surgery: a Personal Construct Analysis

Description: Cognitive ratings that use bipolar constructs based upon similarity and contrast have been shown to be biased towards the similarity pole in approximately a 62/38 ratio. This bias has also been known to shift in the contrastive direction for individuals who have psychiatric problems. This quantitative measure of cognitive change has a potential for characterizing cognitive changes that occur during the disease process, including recovery from disease. … more

A Quasi-Experimental Study of 5th-Graders' Use of Selected Self-Directing Perceptions and Learning Strategies

Description: A major change being advocated in education is that of making students more self-directing; that is, helping them become more responsible for their own learning. The focus of this investigation was on fifth grade students' use of self-directed learning strategies and self-directed perceptual skills. An experimental study was conducted using the nested design for analyzing data obtained from the Guglielmino Self-Directed Learning Readiness Scale, the Zimmerman and Martinez-Pons1 Self-Regulated L… more

Structure and Form in Two Late Works for Flute and Orchestra by Ernest Bloch (1880-1959): Suite Modale (1956) and Two Last Poems (Maybe. . .) (1958) -- a Lecture Recital, Together With Three Recitals of Selected Works of J.S. Bach, Jolivet, Mozart,and Others

Description: The lecture was presented on November 18, 1991. This presentation focused on the only two compositions for solo flute and orchestra by Ernest Bloch. Written during the last three years of the composer's life, the pieces are representative of his last style period. While Suite Modale is neobaroque in style, Two Last Poems is much more subjective. Together they represent a synthesis of many of the stylistic characteristics of Ernest Bloch. The musical parameters discussed included form, melody, t… more
