    SUPPLY RESPONSE TO RISK: THE CASE OF U.S. PINTO BEANS

    Get PDF
    A standard model of behavior under uncertainty is used to suggest price risk variables for use in a positive supply study. The suggested variables are intuitively appealing and empirically tested on Pinto bean data. Linearity is assumed and O.L.S. used. The empirical results show that the risk variables greatly improve the statistical fit of the supply equation, are quantitatively important and that a substantial bias occurs if they are neglected. Policy initiatives to reduce Pinto bean price fluctuations need to consider the risk reducing effects on the supply response.Crop Production/Industries, Risk and Uncertainty,

    The Problem of Evil and the Existence of God

    Get PDF
    In lieu of an abstract, below is the essay\u27s first paragraph. Throughout the history of mankind countless theologians, scholars, and philosophers have grappled with the concept of evil, the existence of God, and if God exists, whether He is omnipotent and representative of infinite goodness. Ever since the first human being gazed up to the heavens and contemplated the origins of natural phenomenon or the reasons dreadful things happen to good people, humanity has engaged in a continuous debate over evil and its relationship to God’s existence and whether He embodies boundless righteousness or tempered vengeance. Numerous scholars and philosophers such as J.S. Mill have argued that the presence of evil within the natural world offers a rational basis to conclude that it isn’t necessary to infer that a being of infinite goodness is at the root of their cause. Others such as St. Thomas Aquinas contend that the existence of evil within our world doesn’t present a dilemma or contradict the idea or concept of an omnibenevolent being or God as its source

    Context-Aware Prediction of Derivational Word-forms

    Derivational morphology is a fundamental and complex characteristic of language. In this paper we propose the new task of predicting the derivational form of a given base-form lemma that is appropriate for a given context. We present an encoder--decoder style neural network to produce a derived form character-by-character, based on its corresponding character-level representation of the base form and the context. We demonstrate that our model is able to generate valid context-sensitive derivations from known base forms, but is less accurate under a lexicon agnostic setting

    Spectroscopic Constants and Vibrational Frequencies for l-C3H+ and Isotopologues from Highly-Accurate Quartic Force Fields: The Detection of l-C3H+ in the Horsehead Nebula PDR Questioned

    Get PDF
    Very recently, molecular rotational transitions observed in the photon-dominated region of the Horsehead nebula have been attributed to l-C3H+. In an effort to corroborate this finding, we employed state-of-the art and proven high-accuracy quantum chemical techniques to compute spectroscopic constants for this cation and its isotopologues. Even though the B rotational constant from the fit of the observed spectrum and our computations agree to within 20 MHz, a typical level of accuracy, the D rotational constant differs by more than 40%, while the H rotational constant differs by three orders of magnitude. With the likely errors in the rotational transition energies resulting from this difference in D on the order of 1 MHz for the lowest observed transition (J = 4 <- 3) and growing as J increases, the assignment of the observed rotational lines from the Horsehead nebula to l-C3H+ is questionable

    Surgical salvage in patients with advanced testicular cancer: indications, risks and outcomes

    Get PDF
    The purpose of this review is to present a comprehensive and updated review of the literature and summary of the indications, risks and outcomes related to salvage, desperation and late relapse surgery for advanced testicular cancer. After completing a thorough review of the current literature, this review has attempted to provide an overview of the indications for salvage, desperation and late relapse retroperitoneal lymph node dissection (RPLND) followed by a summary of the histopathologic and clinical outcomes regarding each. Recent literature, combined with a significant contribution from historical studies suggest that while testicular cancer is a relatively uncommon malignancy overall, it represents the most common solid organ malignancy for young men. Although a significant number of men are cured with a combination of first-line treatments, the remaining men are a diverse and often challenging cohort who require the benefit of expertise to improve their outcomes. The role of surgical strategies in the salvage, desperation and late relapse settings is unquestionable, although the most important question remains who will benefit. This often requires a multi-disciplinary approach at centers specializing in this disease process in order to recognize who should get surgery, what surgery to do and how to minimize the potential morbidity associated with the operation

    The Possible Interstellar Anion CH2CN-: Spectroscopic Constants, Vibrational Frequencies, and Other Considerations

    Get PDF
    It is hypothesized that the A ^1B_1 <- X ^1A' excitation into the dipole-bound state of the cyanomethyl anion (CH2CN-) is proposed as the carrier for one diffuse interstellar band. However, this particular molecular system has not been detected in the interstellar medium even though the related cyanomethyl radical and the isoelectronic ketenimine molecule have been found. In this study we are employing the use of proven quartic force fields and second-order vibrational perturbation theory to compute accurate spectroscopic constants and fundamental vibrational frequencies for ^1A' CH2CN- in order to assist in laboratory studies and astronomical observations

    In defense of biblical literacy in English and American literary studies

    Get PDF
    Dr. William Kerwin, Thesis Supervisor.This study seeks to address a nationwide lack of concern for biblical education in English literary studies. More specifically, it evaluates and offers potential remedies for the current state of biblical illiteracy within the academy. By showing the academic consequences of textual misinterpretation that derive from biblical illiteracy, this essay hopes to educationally and pedagogically promote the adherence of biblical scholarship in English literature. Through biblical explications of select representational texts, this also study intends to effectively contribute to efforts that value foundational biblical education in secular literary academia.Dr. William Kerwin, Thesis Supervisor.Includes bibliographical references (pages 56-60)

    The Failure of Correlation to Describe Out-of-Plane Carbon=Carbon Bending

    Get PDF
    Carbon-carbon multiply bonded systems are improperly described with standard correlation methods and basis sets. For computations of vibrational modes, the out-of- plane bends can be reported as imaginary at worst or simply too low at best. Utilizing the simplest of aromatic structures (cyclopropenylidene) and various levels of theory, this work diagnoses this known behavior for the first time. A combined 1-particle and n-particle basis set effect conspire to produce these non-physical results. When moving from sp2 to sp3 hybridization in the carbon atoms, the larger number of basis functions overcorrects the energy. This is exacerbated by correlation methods. These allow for occupation of the and orbitals in the expanded wave function that combine with the hydrogen s orbitals. As a result, the improperly described space can be further and non-physically stabilized by post-Hartree-Fock correlation. This represents a fundamental problem with at least Hartree-Fock based methods of all flavors in describing carbon. Beyond being a flaw in quantum chemical theory, other repercussions will be present in computations regarding spectroscopy as well as energy and environmental studies where highly-accurate hydrocabon vibrational transitions or thermochemical data are needed

    Deep Ecology in Action: A Cross-Cultural Series of Case Studies on the Conservation Efforts of Monks and Religious Leaders in India, Mongolia, and Thailand

    Get PDF
    Deep ecology is a relatively new branch of study which combines different fields of knowledge such as philosophy, religion, and sociology, on the one hand, with environmental studies, on the other. The basic premise of deep ecology is the interconnectedness of all life and consequently, a concern for the ecological well-being of our planet, which is increasingly threatened by the impact of modern human lifestyles. Recently, there has been a lot of recent attention given to deep ecology movements in Asia. However, these studies often lack the interdisciplinary background in science necessary to assess a real ecological impact. This study is based on a series of case studies was conducted in India, Mongolia, and Thailand across a variety of faiths and locations. By investigating specific cases across cultures and religions and drawing comparisons between the impacts of minority religions and majority religions, the true environmental potential and value of deep ecology movements is analyzed
