Killing Flies With a Shotgun: How the Internet Set a New Journalistic Standard and Style

Killing Flies With a Shotgun: How the Internet Set a New Journalistic Standard and Style

Date: August 2000
Creator: Maher, Kelly M.
Description: Today, both the way a story is told and how long the viewer's attention can be held are often as important as the story itself. This study shows how online media sets new standards for narrative and continues some print traditions. This study focuses on the dialogue between print and online media. A quantitative and qualitative analysis of this dialogue through story length, readability, shovelware and story packaging shows the numerous effects the Internet has had on news media content.

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.

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 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 ...
