News Market and Polarization

The thesis analyzes the news market under two structures: online media and offline media. It differentiates these structures on the basis that online firms can tailor news content to individual readers. This customization capability has implications for the level of price discrimination permissible under these structures. Our analysis reveals that under the online equilibrium, more news stories are supplied at lower prices and to a larger audience. We find that factors that impede firm entry, such as high fixed entry costs, government restrictions, and network effects, make consumers worse off by either reducing the quantity of news in the market, or increasing the prices paid by consumers, or both. We also find the affective polarization to be more pronounced in the online equilibrium when consumers exhibit a preference for sensational news. This suggests that the customization feature of online platforms influences the degree to which a society is affectively polarization. Policymakers should explore strategies to mitigate the effects of affective polarization caused by this channel that is unique to the online media.Thesis (M.Phil.) -- University of Adelaide, School of Economics and Public Policy, 202

Modelling the Hydration kinetics of kidney beans (Phaseolus vulgaris) in sodium salts using Response surface methodology

The present work investigated the effect of salt solutions of sodium chloride, and sodium bicarbonate on the water uptake by kidney beans (Phaseolus vulgaris) at different temperatures (30, 45 and 60 0C). Thirty-five soaking solutions were prepared using NaCl and NaHCO3 to find the optimum soaking treatment and time to maximise the hydration. Hydration kinetics of kidney beans was studied in different concentrations of the salt solutions and at different temperatures by the method of weight gain until equilibrium conditions were attained. Response surface methodology was used to design the experiments and to optimize the levels for minimum soaking time and to maximize the hydration. The soaking solutions affected the mass transfer in both seed coat and cotyledon, demonstrating changes on both proteins and polysaccharides.  Increasing the temperature from 30 to 60 0 C in sodium chloride solution and sodium bicarbonate solution (0.5, 1.0 and 1.5% concentration) decreased the soaking time from >225min and 225 min to 82.5 min and 73.5 min respectively to achieve around 80% hydration. Beans soaked in sodium bicarbonate solution exhibited higher hydration rates than in distilled water followed by sodium chloride solution at the same salt concentration. Soaking for about three hours at 300C resulted in maximum hydration.  The optimum soaking treatment was found to be in a salt solution containing 1.10% NaCl and 0.92% NaHCO3 at 300C which resulted in a soaking time of 193.45 min.  This work demonstrated a simple and non-tedious approach for enhancing the hydration process of grains. &nbsp

The interplay between attention, working memory, and linked neural signatures in visual tracking and inhibition

The aims of this thesis began with investigating whether inattentional blindness was associated with a propensity for lower sensitivity to semantic violations in image textures. Inattentional blindness has recently been investigated through methods such as manipulation of low-level image statistics in artificial textures. However, work in this thesis aimed to transition such research into more natural contexts. Whilst a variety of methods were explored, results specifically related to inattentional blindness and working memory capacity remained inconclusive. Therefore, work in this thesis moved from investigating differences across inattentional blindness groups to how potential strategies of object tracking and relationships to working memory capacity can influence tracking performance. Results from the first half of this thesis provide novel insights into methods that can help to investigate sensitivity to distractors in a naturalistic setting, with both behavioural and neural data. This shift away from investigating inattentional blindness to patterns of tracking across working memory capacity also coincided with a shift to linear mixed effects modelling. This allowed the thesis to remove any artificial grouping through median scores of capacities, and instead focus more on sensitivity across the spectrum. Over five tracking studies, a number of findings suggest of differences across working memory capacity can compensate in performance for such capacity limitations. Findings also suggest that participants, regardless of capacity, employ a post-probe approximation estimation when tracking targets over a trial gap, as opposed to active tracking. Results from the tracking studies emphasise the differing approaches that individuals with varying working memory employ when tracking multiple and single objects

Wavelet Analysis of Shower Track Distribution in High-Energy Nucleus-Nucleus Collisions

A continuous wavelet analysis is performed for pattern recognition of charged particle emission data in 28Si-Ag/Br interaction at 14.5A GeV and in 32S-Ag/Br interaction at 200A GeV. Making use of the event-wise local maxima present in the scalograms, we try to identify the collective behavior in multiparticle production, if there is any. For the first time, the wavelet results are compared with a model prediction based on the ultrarelativistic quantum molecular dynamics (UrQMD), where we adopt a charge reassignment algorithm to modify the UrQMD events to mimic the Bose-Einstein type of correlation among identical mesons—a feature known to be the most dominating factor responsible for local cluster formation. Statistically significant deviations between the experiment and the simulation are interpreted in terms of nontrivial dynamics of multiparticle production
