The Keynesian Concept of Savings

The Keynesian Concept of Savings

Date: 1956
Creator: Ott, David Jackson
Description: The problem under investigation in this study is the determination of the usefulness of the concept of saving set forth by John M. Keynes in his The General Theory of Employment, Interest and Money, both as a method of prediction and prevention of business cycles and as a conceptual framework which is for use in explaining past economic activity, particularly economic growth. The study has a twofold purpose. The first is to evaluate the workability of the Keynesian definitions when applied to existing sources of economic data; to see if a meaningful savings aggregate is a statistical possibility. The second is to attempt to explain in terms of related parts of the rest of Keynes' theoretical system the conclusions reached under the first purpose above.

Keywords in the mist: Automated keyword extraction for very large documents and back of the book indexing.

Date: May 2008
Creator: Csomai, Andras
Description: This research addresses the problem of automatic keyphrase extraction from large documents and back of the book indexing. The potential benefits of automating this process are far reaching, from improving information retrieval in digital libraries, to saving countless man-hours by helping professional indexers creating back of the book indexes. The dissertation introduces a new methodology to evaluate automated systems, which allows for a detailed, comparative analysis of several techniques for keyphrase extraction. We introduce and evaluate both supervised and unsupervised techniques, designed to balance the resource requirements of an automated system and the best achievable performance. Additionally, a number of novel features are proposed, including a statistical informativeness measure based on chi statistics; an encyclopedic feature that taps into the vast knowledge base of Wikipedia to establish the likelihood of a phrase referring to an informative concept; and a linguistic feature based on sophisticated semantic analysis of the text using current theories of discourse comprehension. The resulting keyphrase extraction system is shown to outperform the current state of the art in supervised keyphrase extraction by a large margin. Moreover, a fully automated back of the book indexing system based on the keyphrase extraction system was shown to lead to back ...

The Khan Variations for Solo Marimba by Alejandro Viñao: Musical Analysis and Performance Practice

The Khan Variations for Solo Marimba by Alejandro Viñao: Musical Analysis and Performance Practice

Date: May 2010
Creator: Roberts, John Francis
Description: The Khan Variations is the first work for solo marimba by Argentinean composer Alejandro Viñao (b.1951). Since publication in 2001, Khan Variations has been performed at many international percussion festivals and is often a repertoire choice for performers in the final round of numerous marimba competitions. This thesis and accompanying lecture recital provide a supplemental guide to Alejandro Viñao's Khan Variations, focusing on analytical and structural theory, as well as performance practice, thus filling the void of information on this piece in the percussion community. Khan Variations was jointly commissioned by twelve of the world's prominent marimba performers and educators, including: Michael Burritt, Jack Van Geem, William Moersch, Robert Van Sice, and Nancy Zeltsman. The project organizer of the Khan Variations commission was Nancy Zeltsman, Chair of the Percussion Department at the Boston Conservatory and a leader in the field of commissioning new marimba works. Utilizing William Moersch's organization New Music Marimba as the financial conduit, Zeltsman and her group issued this commission in 1999. Alejandro Viñao studied composition with the Russian composer Jacobo Ficher in Buenos Aires, and Viñao later went on to complete his doctorate in composition from City University in London. His works span the genres of ...

Killing the one you love: Examining cases of intimate partner homicide occurring in Dallas, Texas between the years 1990-1997.

Killing the one you love: Examining cases of intimate partner homicide occurring in Dallas, Texas between the years 1990-1997.

Date: May 2009
Creator: Foster, Rebecca
Description: Research has consistently shown that intimate partner homicide (IPH) rates have been on a steady downward decline over the past two decades. A relatively recent movement in IPH research, however, has emphasized the need for further dissecting the aggregate trends by factors such as gender, race, and victim-offender relationship. In response to these issues, this study looks at the relationship between IPHs and factors such as gender, race, and age. The present study explores officially reported IPH cases in Dallas, Texas between the years 1990-1997. Specific attention will be paid to the victim's and suspect's age, race, and gender. The findings of the study will assist in identifying significant characteristics of these IPH incidents which may lead to a greater understanding of the types of relationships in which IPH is more likely to occur. Studying the relationship between IPHs and these factors, as this research aims to do, is important to understanding what IPH incident characteristics need more attention to help prevent future incidents from occurring. As a result of this research, a better understanding of whether IPH may occur in certain types of relationships will be reached and then can be further utilized to educate.

A Kinematic Comparison Between Greater-and Lesser-Skilled Powerlifters Doing the Traditional Style Deadlift

A Kinematic Comparison Between Greater-and Lesser-Skilled Powerlifters Doing the Traditional Style Deadlift

Date: December 1987
Creator: Canales, Daniel
Description: Comparison kinematic models of the traditional style deadlift are presented. Data was obtained through film and analyzed via computer and computer graphics. The comparison between the models revealed that the greater-skilled: 1. used less trunk flexion from the instant of initial trunk lean to the instant of maximum trunk lean, 2. used less knee extension (in same time interval as 1), and 3. demonstrated a smaller horizontal distance between the body center of mass (CM) and the CM of the bar at the instant the bar left the platform. A trend was also observed in which the greater-skilled subjects demonstrated less thoracic lean than the lesser-skilled group at the time the bar reached knee level.

Kinetic and Chemical Mechanism of 6-phosphogluconate Dehydrogenase from Candida Utilis

Kinetic and Chemical Mechanism of 6-phosphogluconate Dehydrogenase from Candida Utilis

Date: May 1993
Creator: Berdis, Anthony J. (Anthony Joseph)
Description: A complete initial velocity study of the 6-phosphogluconate dehydrogenase from Candida utilis in both reaction directions suggests a rapid equilibrium random kinetic mechanism with dead-end E:NADP:(ribulose 5-phosphate) and E:NADPH:(6- phosphogluconate) complexes. Initial velocity studies obtained as a function of pH and using NAD as the dinucleotide substrate for the reaction suggest that the 2'-phosphate is critical for productive binding of the dinucleotide substrate. Primary deuterium isotope effects using 3-<i-6-phosphogluconate were obtained for the 6-phosphogluconate dehydrogenase reaction using NADP and various alternative inucleotide substrates.

Kinetic and Chemical Mechanism of O-Acetylserine Sulfhydrylase-B from Salmonella Typhimurium

Kinetic and Chemical Mechanism of O-Acetylserine Sulfhydrylase-B from Salmonella Typhimurium

Date: August 1993
Creator: Tai, Chia-Hui
Description: Initial velocity studies of O-acetylserine sulfhydrylase-B (OASS-B) from Salmonella typhimurium using both natural and alternative substrates suggest a Bi Bi ping pong kinetic mechanism with double substrate competitive inhibition. The ping pong mechanism is corroborated by a qualitative and quantitative analysis of product and dead-end inhibition. Product inhibition by acetate is S-parabolic noncompetitive, indication of a combination of acetate with E followed by OAS. These data suggest some randomness to the OASS-B kinetic mechanism. The pH dependence of kinetic parameters was determined in order to obtain information on the acid-base chemical mechanism for the OASS-B reaction. A mechanism is proposed in which an enzyme general base accepts a proton from α-amine of O-acetylserine, while a second enzyme general base acts by polarizing the acetyl carbonyl assisting in the β-elimination of the acetyl group of O-acetylserine. The ε-amine of the active site lysine acts as a general base to abstract the α-proton in the β-elimination of acetate. At the end of the first half reaction the ε-amine of the active site lysine that formed the internal Schiff base and the general base are protonated. The resulting α-aminoacrylate intermediate undergoes a Michael addition with HS‾ and the active site lysine donates its ...

Kinetic and Chemical Mechanism of Pyrophosphate-Dependent Phosphofructokinase

Kinetic and Chemical Mechanism of Pyrophosphate-Dependent Phosphofructokinase

Date: December 1988
Creator: Cho, Yong Kweon
Description: Data obtained from isotope exchange at equilibrium, exchange of inorganic phosphate against forward reaction flux, and positional isotope exchange of 18O from the (βγ-bridge position of pyrophosphate to a (β-nonbridge position all indicate that the pyrophosphate-dependent phosphofructokinase from Propionibacterium freudenreichii has a rapid equilibrium random kinetic mechanism. All exchange reactions are strongly inhibited at high concentrations of the fructose 6-phosphate/Pi and MgPPi/Pi substrate-product pairs and weakly inhibited at high concentrations of the MgPPi/fructose 1,6-bisphosphate pair suggesting three dead-end complexes, E:F6P:Pi, E:MgPPi:Pi, and E:FBP:MgPPi. Neither back-exchange by [32p] nor positional isotope exchange of 18O-bridge-labeled pyrophosphate was observed under any conditions, suggesting that either the chemical interconversion step or a step prior to it limits the overall rate of the reaction. Reduction of the pyridoxal 5'-phosphate-inactivated enzyme with NaB[3H]4 indicates that about 7 lysines are modified in free enzyme and fructose 1,6-bisphosphate protects 2 of these from modification. The pH dependence of the enzyme-reactant dissociation constants suggests that the phosphates of fructose 6-phosphate, fructose 1,6-bisphosphate, inorganic phosphate, and Mg-pyrophosphate must be completely ionized and that lysines are present in the vicinity of the 1- and 6-phosphates of the sugar phosphate and bisphosphates probably directly coordinated to these phosphates. The pH dependence of ...

Kinetic Investigation of the Gas Phase Atomic Sulfur and Nitrogen Dioxide Reaction

Kinetic Investigation of the Gas Phase Atomic Sulfur and Nitrogen Dioxide Reaction

Date: May 2011
Creator: Thompson, Kristopher Michael
Description: The kinetics of the reaction of atomic sulfur and nitrogen dioxide have been investigated over the temperature range 298 to 650 K and pressures from 14 - 405 mbar using the laser flash photolysis - resonance fluorescence technique. The overall bimolecular rate expression k (T) = (1.88 ± 0.49) x10-11 exp-(4.14 ± 0.10 kJ mol-1)/RT cm3 molecule-1 s-1 is derived. Ab initio calculations were performed at the CCSD(T)/CBS level of theory and a potential energy surface has been derived. RRKM theory calculations were performed on the system. It is found that an initially formed SNO2 is vibrationally excited and the rate of collisional stabilization is slower than the rate of dissociation to SO + NO products by a factor of 100 - 1000, under the experimental conditions.

The Kinetic Structures of Metric Temporal Patterns in Selected Beginning Piano Method Series

The Kinetic Structures of Metric Temporal Patterns in Selected Beginning Piano Method Series

Date: August 1994
Creator: Chan, Alton
Description: The purpose of this study was to investigate the kinetic structures or reinforcement schedules of metric temporal patterns (metric combination of note values within a measure) in five best-selling beginning piano method series. Based upon a survey mailed to 98 music dealers, the five best-selling beginning piano method series in 1992 and 1993 were identified as: the Alfred Basic Piano Library, Bastien Piano Basics, David Carr Glover Piano Library, John. W. Schaum Piano Course, and John Thompson Modern Course for Piano. A coding system was developed for identifying the numerical appearances and occurrences of various metric temporal patterns per learning piece within each method series. Several computer programs were written to compute the kinetic structures, scope, and pacing of metric temporal patterns for each method series. The derived data were then compared to delineate relationships between the three analytical variables.

Kinetic studies and computational modeling of atomic chlorine reactions in the gas phase.

Kinetic studies and computational modeling of atomic chlorine reactions in the gas phase.

Date: August 2009
Creator: Alecu, Ionut M.
Description: The gas phase reactions of atomic chlorine with hydrogen sulfide, ammonia, benzene, and ethylene are investigated using the laser flash photolysis / resonance fluorescence experimental technique. In addition, the kinetics of the reverse processes for the latter two elementary reactions are also studied experimentally. The absolute rate constants for these processes are measured over a wide range of conditions, and the results offer new accurate information about the reactivity and thermochemistry of these systems. The temperature dependences of these reactions are interpreted via the Arrhenius equation, which yields significantly negative activation energies for the reaction of the chlorine atom and hydrogen sulfide as well as for that between the phenyl radical and hydrogen chloride. Positive activation energies which are smaller than the overall endothermicity are measured for the reactions between atomic chlorine with ammonia and ethylene, which suggests that the reverse processes for these reactions also possess negative activation energies. The enthalpies of formation of the phenyl and &#946;-chlorovinyl are assessed via the third-law method. The stability and reactivity of each reaction system is further rationalized based on potential energy surfaces, computed with high-level ab initio quantum mechanical methods and refined through the inclusion of effects which arise from the ...

Kinetic Studies and Vibrational Spectra of Disubstituted Metal Carbonyls

Kinetic Studies and Vibrational Spectra of Disubstituted Metal Carbonyls

Date: May 1972
Creator: Jernigan, Robert Thorne
Description: The oxidative elimination reactions of (5-X-phen)Mo(C0)₄ (X = H, CH₃, Cl, NO₂; phen = o-phenanthroline) and (3,4,7,8-(CH₃)₄-phen)Mo(CO)₄ with mercuric chloride in acetone have been investigated. In these reactions, a carbon monoxide group is replaced by two univalent ligands, accompanied by the corresponding increase in coordination number and formal oxidation state of the central metal atom, to give products of the type, (X-phen)Mo(CO)₃(Cl)HgCl. With the exception of (3,4,7,8-(CH₃)₄-phen), the substituted o-phenanthrolines were selected so as to minimize steric differences from one substrate to another while obtaining the widest range of pKₐ of the ligand.

Kinetic Studies of Hydroxyl and Hydrogen Atom Reactions

Kinetic Studies of Hydroxyl and Hydrogen Atom Reactions

Date: May 2002
Creator: Hu, Xiaohua
Description: Gas phase kinetics of the reactions involving hydroxyl radical and hydrogen atom were studied using experimental and ab initio theoretical techniques. The rate constant for the H + H2S reaction has been measured from 298 to 598 K by the laser photolysis/resonance fluorescence (LP-RF) technique. The transition state theory (TST) analysis coupled with the measurements support the suggestion that the reaction shows significant curvature in the Arrhenius plot. The LP-RF technique was also used to measure the rate constant of the H + CH3Br reaction over the temperature range 400-813 K. TST and density functional theory (DFT) calculations show that the dominant reaction channel is Br-abstraction. The reaction H + CF2=CF-CF=CF2 was first studied by flash photolysis/resonance fluorescence (FP-RF) method. The experiments of this work revealed distinctly non-Arrhenius behavior, which was interpreted in terms of a change in mechanism. DFT calculations suggest that the adduct is CF2H-CF•-CF=CF2. At lower temperatures a mixture of this molecule and CF2•-CFH-CF=CF2 is likely. The theoretical calculations show that H atom migrates in the fluoroethyl radicals through a bridging intermediate, and the barrier height for this process is lower in the less fluorinated ethyl radical. High level computations were also employed in studies of the ...
