Tracing The History Of Grounded Theory Methodology: From Formation To Fragmentation, Méabh Kenny, Robert Fourie

The Qualitative Report

There are very few articles, which track the history of Grounded Theory (GT) methodology from its tentative conception to its present divisions. This journal article addresses the dearth by tracing the history of GT methodology from its conception in the 1960’s, discussing the context of its composition, character, and contribution. Subsequently, the article follows the maturation of GT which is characterised by a series of contentious and, at times, antagonistic academic debates. The crux of these debates centres on disputes over core tenets of GT and have resulted in three dominant and divergent configurations of the GT methodology: Classic, Straussian, …

Abstract

Electromagnetic ion cyclotron (EMIC) waves were observed at multiple observatory locations for several hours on 17 January 2013. During the wave activity period, a duskside relativistic electron precipitation (REP) event was observed by one of the Balloon Array for Radiation belt Relativistic Electron Losses (BARREL) balloons and was magnetically mapped close to Geostationary Operational Environmental Satellite (GOES) 13. We simulate the relativistic electron pitch angle diffusion caused by gyroresonant interactions with EMIC waves using wave and particle data measured by multiple instruments on board GOES 13 and the Van Allen Probes. We show that the count rate, the energy …

Baseline Survey For Street Dogs In Guam, John D. Boone

Stray and Feral Animal Populations Collection

As is the case for many inhabited islands in Pacific region, dogs are common, including freeroaming street dogs that may be owned or unowned. Reproduction among dogs is largely unchecked, and many owned dogs do not receive adequate levels of basic care in the home or veterinary care when needed. For all of these reasons, Humane Society International (HSI) is exploring options for improving the management of street dog populations and promoting better treatment and care of all dogs on Guam and on the nearby islands of Rota and Saipan.

Comparison In Factors Affecting Electrochemical Properties Of Thermal-Reduced Graphene Oxide For Supercapacitors, Peng Xiao, Da-Hui Wang, Jun-Wei Lang

Journal of Electrochemistry

In this paper, thermal-reduced graphene oxide (T-RGO) materials are synthesized by modified Hummer’s method, followed by thermal reduction under argon atmosphere at different temperatures. Electrochemical investigations show that, for T-RGO electrodes, good electrical conductivity is necessary and the surface functional groups play more significant role than the specific surface area in determining the electrochemical capacitance. The T-RGO obtained at 900 °C (T-RGO900) with a relatively high Brunauer-Emmett-Teller (BET) surface area (314 m²·g^-1) and a high electrical conductivity (2421 S·m^-1) shows a low specific capacitance of 56 F·g^-1. In comparison, the T-RGO obtained …

Kinetics And Mechanism Of Acidic Electroless Ni-P Plating, Zhi-Hui Xie, Gang Yu

Journal of Electrochemistry

Electrochemical behaviors of electroless nickel (EN) plating in three systems, namely, cathodic, anodic and complete bath solutions were investigated by polarization methods. The curves in the complete baths were not entirely consistent with those expected from a combination of the anodic and cathodic polarization curves, which implies that the anodic and cathodic reactions of the EN plating are interdependent. The effects of concentration of nickel ions, hypophosphite and pH on the polarization parameter and deposition rate in a complete bath were also discussed and compared by performing electrochemical and gravimetrical measurements. Based on these variations in the deposition potential and …

Resolve Mono-Electronic Process In The Voltammetric Behaviors Of Multi-Redox Bis-Coenzyme Q0, Hao Zhou, Yi-Tao Long

Journal of Electrochemistry

A widely held concept in electrochemistry is that truly elementary electron-transfer reactions always involve the exchange of one electron, therefore, an overall process involving a change of n electrons must involve n distinct electron-transfer steps. It is highly desirable to resolve multiple-step electron transfer reactions into each electron transfer step. The electrochemical behaviors of coenzyme Q₀ and methylene-bridged Bis-coenzyme Q₀ were investigated by cyclic voltammetry and square wave voltammetry in nonaqueous dichloromethane containing 0.15 mol·L^-1 Bu₄NClO₄ as the supporting electrolyte. The redox reaction of coenzyme Q₀ is well described as two chemically reversible …

Winter Activity Of Bats In Southeastern Nebraska: An Acoustic Study, Jeremy A. White, Brett R. Andersen, Hans W. Otto, Cliff A. Lemen, Patricia W. Freeman

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Many North American bats are active outside hibernacula in winter, but no information on winter activity has been reported for Nebraska. We recorded activity of bats during two winters (December-February 2012-2013 and 2013-2014) at one location in southeastern Nebraska with an acoustic detector. Bats were active throughout both winters and temperature at sunset was a good predictor of bat activity. Red bats (Lasiurus borealis) were active at our site in early December but were not recorded later in winter. We suspect these individuals were late migrants to more southern wintering sites. Big brown bats (Eptesicus fuscus) …
