Impact of eWOM Source Characteristics on The Purchasing Intention.
… consumers. The privacy and cost-effectiveness characteristics of e-mail make it an important communication medium for consumers. Consumers use e-mail to exchange a variety of information including electronic word of mouth (eWOM) about products, services and organisations. The travel industry, …

Online persuasion: the influence of message cues and source characteristics
Despite the exponential growth in internet usage for personal communication over the last 10 years (Madden & Zickuhr, 2011) little is known of the online interpersonal persuasion process. Whilst some psychological research has been undertaken in this area, the findings are somewhat contradictory …

Investigation of the acoustic source characteristics of high energy laser pulses models and experiment
… of using high energy laser pulses as an acoustic source for naval applications. Research conducted in the 1970's and 80's shows that sound production from laser pulses is most efficient when the energy density of the pulse exceeds the threshold required for plasma formation. The resulting acoustic …

Estimating glottal voicing source characteristics by measuring and modeling the acceleration of the skin on the neck
In the clinical management of voice patients, quantifying vocal function is becoming increasingly important both for corroborating clinicians' subjective impressions during a voice evaluation and for assessing the effectiveness of surgery or voice therapy. Current devices for quantifying vocal …

A Mixed-Method Examination of Social Media Influencers’ Source Characteristics in Sponsored Health Campaign Messaging: An Application of Psychological Reactance Theory
… dissertation was to (a) uncover micro-influencer characteristics that mitigate reactance toward sponsored social media posts, (b) investigate whether influencers induce less reactance than non- influencers when disseminating sponsored health content, and (c) experimentally test whether influencer …

Active tectonics and earthquake hazards in continental mountain ranges and foreland basins
… on mountain range fronts. The earthquake source characteristics and foreland basin structure were varied within reasonable geological bounds, and the earthquake-induced ground shaking was calculated. The earthquake source parameters were determined to be the dominant control on the amount …

Optimisation of accelerator optics and the application of nuclear microscopy to the biomedical field
… LABS, as well as optimization of the beam characteristics along the Van de Graaf acceleratore beamlines in general, relevant modifications were implemented. The design and layout of the beamlines in general, relevant modifications were implemented. The design and layout of the beamlines …

Nonlinear optical frequency conversion of mode-locked all-solid-state lasers
… One objective is to create an ultrashort-pulsed source that is tunable between λ= 600nm and λ= 700nm, since currently no other laser gain media exists that covers this region of the electromagnetic spectrum. This novel source is intended for application to multiphoton imaging. The first …

Physics-based aeroacoustic modelling of bluff-bodies
… were solved numerically to predict the noise source characteristics and the resulting acoustic far-field. Three-dimensional compressible Navier-Stokes simulations were performed to solve the unsteady turbulent near-field flow and the acoustic analogy was used to predict the resulting far-field …

The Effects of Knowledge Transfer On Complex Problem Representation and Judgment in Auditing
… within the media richness theory, because the source of information is impersonal. However, if audit firms can successfully transform the transfer of information within the audit files from being solely formal document screens to also incorporate personal source characteristics, they will …

Analyzing the Collective Behavior of Earthquakes to Understand Fault Mechanisms Better
… clustering and the analysis of earthquake source characteristics in the Southwestern Alps helped explain differences in fault mechanisms in the two most active areas of the study region. My results also point towards non self-similar earthquakes. Along the North Anatolian Fault, in addition …

Fast-ion spectrometry of ICF implosions and laser-foil experiments at the omega and MTW laser facilities
… amount of preheat depends on the hot-electron source characteristics and the time duration over which electrons can deposit energy into the fuel. This time duration is prescribed by the evolution of a sheath that surrounds the implosion and traps electrons. Fast-ion measurements have been used …

Propagation Of Sound In The Vicinity Of Rigid Porous Interfaces
… the sound field emanating from a monopole source above and below a rigid porous interface. The solutions can be expressed in a form that resembles the classical Weyl-Van der Pol formula. A heuristic method is then proposed to remove the singularity within the asymptotic solution via …
