description: We report the discovery of five quasars with redshifts of 4.67 - 5.27 and z'-band magnitudes of 19.5-20.7 M_B ~ -27. All were originally selected as distant quasar candidates in optical/near-infrared photometry from the Sloan Digital Sky Survey (SDSS), and most were confirmed as probable high-redshift quasars by supplementing the SDSS data with J and K measurements. The quasars possess strong, broad Lyman-alpha emission lines, with the characteristic sharp cutoff on the blue side produced by Lyman-alpha forest absorption. Three quasars contain strong, broad absorption features, and one of them exhibits very strong N V emission. The amount of absorption produced by the Lyman-alpha forest increases toward higher redshift, and that in the z=5.27 object (D_A ~ 0.7) is consistent with a smooth extrapolation of the absorption seen in lower redshift quasars. The high luminosity of these objects relative to most other known objects at z >~ 5 makes them potentially valuable as probes of early quasar properties and of the intervening intergalactic medium.

description: A turbulent vortex street in an air flow interacting with a disperse droplet population is investigated in a wind tunnel. Non-intrusive measurement techniques are used to obtain data for the air velocity and the droplet velocity. The process is modeled with a population balance system consisting of the incompressible Navier--Stokes equations and a population balance equation for the droplet size distribution. Numerical simulations are performed that rely on a variational multiscale method for turbulent flows, a direct discretization of the differential operator of the population balance equation, and a modern technique for the evaluation of the coalescence integrals. After having calibrated two unknown model parameters, a very good agreement of the experimental and numerical results can be observed.

 Eine turbulente Wirbelstraße in einer Luftströmung mit einer dispergierten Tröpfchenpopulation wird in einem Windkanal untersucht. Nichtintrusive Messtechniken werden verwendet, um Daten bezüglich der Luft-- und Tröpfchengeschwindigkeiten zu gewinnen. Der zu Grunde liegende Prozess wird mit einem Populationsbilanzsystem modelliert, welches aus den inkompressiblen Navier--Stokes--Gleichungen und einer Populationsbilanzgleichung für die Tröpfchenverteilungsdichte besteht. Numerische Simulationen werden durchgeführt, welche ein variationelle Mehrskalenmethode für turbulente Strömungen, eine direkte Diskretisierung des Differentialoperators der Populationsbilanzgleichung und ein modernes Verfahren zur Berechnung der Koaleszensintegrale verwenden. Nachdem zwei unbekannte Modellparameter kalibriert worden sind, kann eine sehr gute Übereinstimmung der experimentellen und numerischen Ergebnisse beobachtet werden.

description: The far-reaching impacts of global warming on precipitation patterns warrant our unwavering attention. As the atmosphere heats up, heightened water vapor levels lead to more intense and frequent severe weather, exacerbating the risk of floods. Conversely, shifts in rainfall distribution could incite prolonged droughts and diminished water access in specific regions. Given the societal and economic repercussions of these extremes, comprehending their evolving nature becomes paramount. This study employs General Circulation Models (GCMs) from the Coupled Model Intercomparison Project Phase 6 (CMIP6) to explore shifts in rainfall and their consequences for Texas amid global warming. In Chapter 2, I meticulously evaluate the performance of the CMIP6 GCMs in representing the observed rainfall characteristics over Texas. Subsequently, I scrutinize projections from the most accurate GCMs to estimate changes in extreme rainfall events. The analysis reveals a more pronounced increase in the annual maximum 5-day rainfall (Rx5day) in the near-future (2021-2050) than long-term (2071-2100) when compared to the historical period (1985-2014). In Chapter 3, I use a data driven approach to develop a statistical relationship between flood height at critical infrastructures and precipitation during historical tropical cyclones (TC) in Texas. This relationship is then extrapolated to anticipate future flood risks based on projected extreme rainfall. The findings illuminate heightened vulnerabilities to damage and disruptions from future TC-induced floods in specific areas. In Chapter 4, I assess prospective changes in streamflow within the Colorado River Basin (CRB) using GCMs selected based on their ability to represent the observed climatic characteristics over the CRB. The results signal substantial alternations in CRB streamflow and an escalated probability of extreme flow occurrences. Cumulatively, this dissertation underscores the urgency for adaptable strategies to confront the intricate challenges stemming from evolving Texas rainfall patterns in a warming climate.

description: The moving mesh PDE (MMPDE) method for variational mesh generation and adaptation is studied theoretically at the discrete level, in particular the nonsingularity of the obtained meshes. Meshing functionals are discretized geometrically and the MMPDE is formulated as a modified gradient system of the corresponding discrete functionals for the location of mesh vertices. It is shown that if the meshing functional satisfies a coercivity condition, then the mesh of the semi-discrete MMPDE is nonsingular for all time if it is nonsingular initially. Moreover, the altitudes and volumes of its elements are bounded below by positive numbers depending only on the number of elements, the metric tensor, and the initial mesh. Furthermore, the value of the discrete meshing functional is convergent as time increases, which can be used as a stopping criterion in computation. Finally, the mesh trajectory has limiting meshes which are critical points of the discrete functional. The convergence of the mesh trajectory can be guaranteed when a stronger condition is placed on the meshing functional. Two meshing functionals based on alignment and equidistribution are known to satisfy the coercivity condition. The results also hold for fully discrete systems of the MMPDE provided that the time step is sufficiently small and a numerical scheme preserving the property of monotonically decreasing energy is used for the temporal discretization of the semi-discrete MMPDE. Numerical examples are presented
Medium Effects on Binary Collisions with the Delta Resonance

Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: To facilitate the relativistic heavy-ion calculations based on transport equations, the binary collisions involving a $Δ$ resonance in either the entrance channel or the exit channel are investigated within a Hamiltonian formulation of $πNN$ interactions. An averaging procedure is developed to define a quasi-particle $Δ^*$ and to express the experimentally measured $NN\rightarrow πNN$ cross section in terms of an effective $NN\rightarrow NΔ^\ast$ cross section. In contrast to previous works, the main feature of the present approach is that the mass and the momentum of the produced $Δ^*$'s are calculated dynamically from the bare $Δ\leftrightarrow πN$ vertex interaction of the model Hamiltonian and are constrained by the unitarity condition. The procedure is then extended to define the effective cross sections for the experimentally inaccessible $NΔ^\ast \rightarrow NN$ and $NΔ^\ast \rightarrow NΔ^\ast$ reactions. The predicted cross sections are significantly different from what are commonly assumed in relativistic heavy-ion calculations. The $Δ$ potential in nuclear matter has been calculated by using a Bruckner-Hartree-Fock approximation. By including the mean-field effects on the $Δ$ propagation, the effective cross sections of the $NN\rightarrow NΔ^\ast$, $NΔ^\ast \rightarrow NN$ and $NΔ^\ast \rightarrow NΔ^\ast$ reactions in nuclear matter are predicted. It is demonstrated that the density dependence is most dramatic in the energy region close to the pion production threshold.

description: The evolution of star clusters is studied using N-body simulations in which the evolution of single stars and binaries are taken self-consistently into account. Initial conditions are chosen to represent relatively young Galactic open clusters, such as the Pleiades, Praesepe and the Hyades. The calculations include a realistic mass function, primordial binaries and the external potential of the parent Galaxy. Our model clusters are generally significantly flattened in the Galactic tidal field, and dissolve before deep core collapse occurs. The binary fraction decreases initially due to the destruction of soft binaries, but increases later because lower mass single stars escape more easily than the more massive binaries. At late times, the cluster core is quite rich in giants and white dwarfs. There is no evidence for preferential evaporation of old white dwarfs, on the contrary the formed white dwarfs are likely to remain in the cluster. Stars tend to escape from the cluster through the first and second Lagrange points, in the direction of and away from the Galactic center. Mass segregation manifests itself in our models well within an initial relaxation time. As expected, giants and white dwarfs are much more strongly affected by mass segregation than main-sequence stars. Open clusters are dynamically rather inactive. However, the combined effect of stellar mass loss and evaporation of stars from the cluster potential drives its dissolution on a much shorter timescale than if these effects are neglected. The often-used argument that a star cluster is barely older than its relaxation time and therefore cannot be dynamically evolved is clearly in error for the majority of star clusters.

description: The classical Johnson-Mehl-Avrami-Kolmogorov approach for nucleation and growth models of diffusive phase transitions is revisited and applied to model the growth of ferrite in multiphase steels. For the prediction of mechanical properties of such steels, a deeper knowledge of the grain structure is essential. To this end, a Fokker-Planck evolution law for the volume distribution of ferrite grains is developed and shown to exhibit a log-normally distributed solution. Numerical parameter studies are given and confirm expected properties qualitatively. As a preparation for future work on parameter identification, a strategy is presented for the comparison of volume distributions with area distributions experimentally gained from polished micrograph sections.

description: This thesis studied the development of probabilistic safety assessment (PSA) tools and methodologies for small fishing boats (SFB) use. The tools and methodologies developed were applied to case study scenarios, and they showed high prospects in identifying safety challenges when SFBs are fishing. Because, in most cases, SFBs in remote fishing communities lack adequate safety equipment to prevent accidents at sea, the PSA tools and methodologies are primarily aimed at these communities. The SFB size in the marine environment, amidst harsh sea conditions, endangers fishers’ safety during fishing voyages. Lapses that may be present in the SFB safety regulation and monitoring at individual country levels allow some SFBs not to have onboard the appropriate equipment to understand, monitor, and manage the safety challenges encountered. These safety challenges are rooted in the accidents SFBs encounter. Although man or person overboard, main propulsion system failure, loss of situational awareness, and loss of stability were frequent in most SFB accident and incident databases, the research on these mostly led to only uncovering their causation factors. Linking these factors and their incidents to yield PSA tools capable of explaining how the incidents occur was yet to be done. The quantitative risk analysis (QRA) and Bayesian network (BN) modelling were identified through a literature review as rigorous methods for developing PSA tools and methodologies, so they were applied accordingly to the named accidents and incidents. The novel contributions the thesis made to the body of knowledge in SFB safety and maritime research, in general, are (1) the development of a unique methodology called the goal-directed risk identification technique (Goal-DRIT) for listing risk factors in highly complex systems; (2) naïve Bayes’ application to fill conditional probability tables (CPT) with probability scores; (3) development of a rule-based system for guiding subject-matter experts in probability elicitation exercises, to minimise variability in experts scores and (4) development of independence of causal influence model using De Morgan gates for both qualitative risk analysis and probabilistic risk analysis. The thesis study is recommended for the fishing industry (particularly the SFB sector), national and international maritime administrations, and SFB safety researchers.
Hydrogeochemistry of submarine groundwater discharge (SGD) in a volcanic coastal area : Mabini Peninsula, the Philippines

description: Submarine Groundwater Discharge (SGD) delivers water and transports chemicals to the ocean. It is essential in the global geochemical cycle and coastal water quality. Mabini Peninsula in the Philippines is a volcanic coastal area that has been noted as the center of the Coral Triangle, home to the world’s most biodiverse reef ecosystem. It is important to study SGD in the area that hosts these vital ecosystems. I aim to understand the hydrogeochemistry of SGD and identify the processes behind it. I collected a total of 11 SGD samples at various depths, ranging from the intertidal zone to ~60 m underwater. I find that the springs emit thermal, acidic waters (~50°C, pH ~5.5-6.5) with high dissolved CO₂ (P [subscript CO2] ~14,700-54,000 ppm). The warmer temperature suggests that thermal convection driven by a volcanic heat source is a significant driver of SGD in the area. Meanwhile, high P [subscript CO2] is consistent with magmatic component. The hydrogen and oxygen isotope composition (δD = -24‰ to -2‰ and δ¹⁸O = -2.4‰ to +1.8‰) indicate that the spring waters are a mixture of three end-members: terrestrial groundwater, recirculated seawater, and hydrothermal water. Overall, the SGD waters are rich in major ions compared to the average groundwater (Ca²⁺ = 394.55–550.55 mg/L; K⁺ = 365.12–512.94 mg/L; Na⁺ = 5720.49–10269.01 mg/L; Mg²⁺ = 312.80–1258.55 mg/L, Cl⁻ = 10497.09–18652.77 mg/L, and SO₄²⁻ = 665.41–2585.57 mg/L). The SGD waters are also significantly enriched in Si³⁺ (6.94–87.72 mg/L), As³⁺ (60–3222 µg/L), and B³⁺ (4.04–74.95 mg/L). All three indicate magmatic water contribution. I interpreted major ions using various plots which discriminate processes, including: mixing diagrams with the three end-members and Giggenbach diagram for geothermal solute equilibria. The mixing plots show that most spring waters are outside the mixing triangle, implying the presence of low-temperature water-rock interaction. The geothermal solute equilibria diagram reveals that the spring waters consist of weakly to moderately mineralized solutions. Understanding the unique properties and hydrogeochemistry of SGD water in this site can help us to understand how it impacts and contributes to the biodiverse ecosystems in the Coral Triangle.

Coherence generating power of quantum dephasing processes

description: We provide a quantification of the capability of various quantum dephasing processes to generate coherence out of incoherent states. The measures defined, admitting computable expressions for any finite Hilbert space dimension, are based on probabilistic averages and arise naturally from the viewpoint of coherence as a resource. We investigate how the capability of a dephasing process (e.g., a non-selective orthogonal measurement) to generate coherence depends on the relevant bases of the Hilbert space over which coherence is quantified and the dephasing process occurs, respectively. We extend our analysis to include those Lindblad time evolutions which, in the infinite time limit, dephase the system under consideration and calculate their coherence generating power as a function of time. We further identify specific families of such time evolutions that, although dephasing, have optimal (over all quantum processes) coherence generating power for some intermediate time. Finally, we investigate the coherence generating capability of random dephasing channels.

description: A new framework for exploiting information about the renormalization group (RG) behavior of gravity in a dynamical context is discussed. The Einstein-Hilbert action is RG-improved by replacing Newton's constant and the cosmological constant by scalar functions in the corresponding Lagrangian density. The position dependence of $G$ and $Λ$ is governed by a RG equation together with an appropriate identification of RG scales with points in spacetime. The dynamics of the fields $G$ and $Λ$ does not admit a Lagrangian description in general. Within the Lagrangian formalism for the gravitational field they have the status of externally prescribed ``background'' fields. The metric satisfies an effective Einstein equation similar to that of Brans-Dicke theory. Its consistency imposes severe constraints on allowed backgrounds. In the new RG-framework, $G$ and $Λ$ carry energy and momentum. It is tested in the setting of homogeneous-isotropic cosmology and is compared to alternative approaches where the fields $G$ and $Λ$ do not carry gravitating 4-momentum. The fixed point regime of the underlying RG flow is studied in detail.

description: For a discrete dynamics defined by a sequence of bounded and not necessarily invertible linear operators, we give a complete characterization of exponential stability in terms of invertibility of a certain operator acting on suitable Banach sequence spaces. We connect the invertibility of this operator to the existence of a particular type of admissible exponents. For the bounded orbits, exponential stability results from a spectral property. Some adequate examples are presented to emphasize some significant qualitative differences between uniform and nonuniform behavior.

description: Coherent pion photoproduction, $d(γ,π^0)d$, is calculated in a coupled channels approach in momentum space using an elementary production operator that includes Born terms, vector meson exchange and $M1/E2$ $Δ$-resonance excitation. The final state interaction is treated in the KMT multiple scattering approach that describes $πd$ elastic scattering well. Differential cross sections are found to agree well with existing ($γ, π^0$) data. The polarization observables $Σ, iT_{11}$ and the tensor analyzing powers are predicted for forthcoming experiments. A number of transparent relationships between polarization observables and the elementary production operator is derived. Finally, calculations are performed for coherent eta photoproduction, $d (γ, η)d$, in the threshold region which agree well with a very recent Mainz experiment.

Ground Edge based LIDAR Localization without a Reflectivity Calibration for Autonomous Driving

description: In this work we propose an alternative formulation to the problem of ground reflectivity grid based localization involving laser scanned data from multiple LIDARs mounted on autonomous vehicles. The driving idea of our localization formulation is an alternative edge reflectivity grid representation which is invariant to laser source, angle of incidence, range and robot surveying motion. Such property eliminates the need of the post-factory reflectivity calibration whose time requirements are infeasible in mass produced robots/vehicles. Our experiments demonstrate that we can achieve better performance than state of the art on ground reflectivity inference-map based localization at no additional computational burden.

A matched asymptotic analysis -- appropriate to the limit of decreasing interface thickness -- demonstrates the consonance of our theory with a general, thermodynamically consistent sharp-interface theory that accounts for anisotropic interfacial energy and entropy, interfacial tension and shear, and dissipative transition kinetics."

description: A numerical double burst model of the chemical evolution of gas-rich dwarf galaxies has been developed. The model is fitted to a sample of N/O, O/H, Y and gas fraction observations, where N/O and O/H are the relative abundances by number of nitrogen to oxygen and oxygen to hydrogen, respectively. Y is the abundance by mass of helium. Closed models as well as models including enriched outflow, ordinary outflow and ordinary outflow combined with inflow are considered.The bursts are assumed to be instantaneous but ordered in pairs to explain the scatter in N/O-O/H. The method of gas fraction fitting is revised, and it is found that it is very important to specify whether dwarf irregulars (dIrrs) or blue compact galaxies (BCGs) are considered. Effective enriched winds fail when fitting N/O, whereas closed models, models with ordinary winds or a combination of ordinary winds and inflow are all viable.

The high-resolution images enable us to perform rigorous two-dimensional image modeling to decouple the luminous central point source from the host galaxy, which, when warranted, is further decomposed into its principal structural components (bulge, bar, and disk). In many cases, care must be taken to account for structural complexities such as spiral arms, tidal features, and overlapping or interacting companion galaxies. We employ Fourier modes to characterize the degree of asymmetry of the light distribution of the stars, as a quantitative measure of morphological distortion due to interactions or mergers. We examine the dependence of the physical parameters of the host galaxies on the properties of the AGNs, namely radio-loudness and the width of the broad emission lines. In accordance with previous studies, narrow-line (H$β$ FWHM $\leq 2000$ km~s$^{-1}$) type 1 AGNs, in contrast to their broad-line (H$β$ FWHM $> 2000$ km~s$^{-1}$) counterparts, are preferentially hosted in later type, lower luminosity galaxies, which have a higher incidence of pseudo-bulges, are more frequently barred, and are less morphologically disturbed. This suggests narrow-line type 1 AGNs experienced a more quiescent evolutionary history driven primarily by internal secular evolution instead of external dynamical perturbations. The fraction of AGN hosts showing merger signatures is larger for more luminous sources. Radio-loud AGNs generally preferentially live in earlier type (bulge-dominated), more massive hosts, although a minority of them appears to contain a significant disk component. We do not find convincing evidence for enhanced merger signatures in the radio-loud population.

description: The analysis of material models which allow for complete damage is of major interest in material sciences and has received an increasing attraction in the recent years. In this work, we study a degenerating evolution inclusion describing complete damage processes coupled with a quasi-static force balance equation and mixed boundary conditions. For a realistic description, the inclusion is considered on a time-dependent domain and degenerates when the material undergoes maximal damage. We propose a weak formulation where the differential inclusion is translated into a variational inequality in combination with a total energy inequality. The damage variable is proven to be in a suitable SBV-space and the displacement field in a local Sobolev space. We show that the classical differential inclusion and the boundary conditions can be regained from the notion of weak solutions under additional regularity assumptions. The main aim is to prove global-in-time existence of weak solutions for the degenerating system by performing a degenerate limit. The variational inequality in the limit is recaptured by suitable approximation techniques whereas the energy inequality is gained via Gamma-convergence techniques. To establish a displacement field for the elastic behavior in the limit, a rather technical representation result of nonsmooth domains by Lipschitz domains, which keep track of the Dirichlet boundary, is proven.

description: Submarine groundwater discharge (SGD), or the flow of groundwater from land to sea, transports different constituents to the coast, such as nutrients, chemicals, and dissolved metals. In volcanic regimes, groundwater might have especially high concentrations of these constituents when, it is hydrothermal in origin. The Verde Island Passage, which lies within the Coral Triangle in the western Pacific, has been designated a marine protected area, as it is home to over thousands of different species of fish and coral reefs. Interactions of this constituent-rich groundwater with coastal waters through fractured volcanic rock can either pose a threat to or promote coastal ecosystem productivity and health. Because of this setting, it is known that SGD is a prevalent source of constituents, but how much and specifically where it is occurring is unknown. Thermal Infrared (TIR) remote sensing has gained popularity as a method of detecting SGD as it helps to resolve spatial variability issues that are inevitably accompanied by this phenomenon. Here, we investigate the use of TIR satellite and airborne remote sensing, coupled with ground-based field measurements including thermistor rods and fiber-optic distributed temperature sensing to identify and quantify submarine groundwater discharge in a coastal area of the Verde Island Passage. This study utilizes USGS Landsat 8 TIR sensor to regionally denote SGD plumes via temperature measurements of ocean water, as well as local airborne TIR remote sensing which provides a finer spatial resolution than its satellite counterpart. This study also employs a 1 km-long fiber optic cable to continuously measure temperature along the coast for the very first time in this region, and thermistor rods buried in the seabed under 20-30 feet of water to measure vertical temperature flux. Results from these approaches reveal multiple SGD signals in both the intertidal and subtidal zones, and tens of meters offshore, with temperatures reaching up to 80°C and estimated fluxes reaching as high as 1.5 m/d. From these approaches, we conclude that airborne TIR remote sensing and vertical thermal profiling are the most feasible thermal sensing methods employed in the study area, as they capture regional to local and point scaled SGD, which yield plume location, morphology, and flux. This study serves as a foundation for mapped SGD locations which can be used in conjunction with flux estimations in future temperature and flow modeling of SGD in the region. This study also has implications on potential outflow points of natural hydrothermal constituents and/or polluted groundwater, which can be of benefit to ecosystem and resource management.
Bulk inflaton shadows of vacuum gravity

description: We introduce a $(5+m)$-dimensional vacuum description of five-dimensional bulk inflaton models with exponential potentials that makes analysis of cosmological perturbations simple and transparent. We show that various solutions, including the power-law inflation model recently discovered by Koyama and Takahashi, are generated from known $(5+m)$-dimensional vacuum solutions of pure gravity. We derive master equations for all types of perturbations, and each of them becomes a second order differential equation for one master variable supplemented by simple boundary conditions on the brane. One exception is the case for massive modes of scalar perturbations. In this case, there are two independent degrees of freedom, and in general it is difficult to disentangle them into two separate sectors.

Depositional environments in the middle part of the Glen Rose Limestone (Lower Cretaceous), Blanco and Hays Counties, Texas

description: A 70-foot interval from the middle part of the Glen Rose Limestone (Lower Cretaceous) has been sampled at 35 localities in central Texas for the purpose of reconstructing vertical and lateral changes of depositional environment on the San Marcos Platform. A marker unit, the Corbula Interval, crops out in the center of the stratigraphic section. The middle Glen Rose was deposited as a mosaic of shoal-water lithotopes in a broad lagoon behind the Gulf Coast Reef Trend. Over part of the Platform the sea was sufficiently shallow to permit the development of local offlap sequences. As a result, intertidal and supratidal units comprise a significant proportion of many local facies successions. In Blanco and Hays counties there are two distinct patterns of vertical facies succession. Closer to the Llano Uplift (Blanco County) 3 to 5 offlap cycles are seen in the 70-foot interval. These involve a gradational trend from subtidal through supratidal facies. Each cycle is bracketed by sharply-defined bedding planes. The cycles are regressional and result from the progradation of carbonate mud flats into a shelf sea. Further to the east and more distant from the Llano Uplift (Hays County) the facies tract lacks the imbricated succession of regressive cycles. Subtidal units comprise the bulk of the section. The difference in the vertical facies pattern for the two areas may result from their relationship to the ancient shoreline. Because the Llano Uplift was emergent during deposition of the middle Glen Rose, the outcrops closest to the Uplift contain abundant evidence of tidal flat sedimentation. Mud mounds and small islands adjacent to land may have served as nuclei for the development of local offlap sequences. To the southeast (Hays County) the shelf sea may have been slightly deeper and probably lacked the nuclei necessary to initiate these sequences. One complete cycle, the Corbula Cycle, crops out in both areas and may record a brief period of emergence for most of the San Marcos Platform

description: A dewetting viscous film develops a characteristic fluid rim at its receding edge due to mass conservation. In the course of the dewetting process the rim becomes unstable via an instability of Rayleigh-Plateau type. An important difference exists between this classic instability of a liquid column and the rim instability in the thin film as the growth of the rim is continuously fueled by the receding film. We explain how the development and macroscopic morphology of the rim instability are controlled by the slip of the film on the substrate. A single thin-film model captures quantitatively the characteristics of the evolution of the rim observed in our experiments.
“If we talk about politics on WhatsApp, it’s a joke” : understanding perceptions of WhatsApp among Mexican-American users through imagined affordances and media ideologies

description: In recent years, users have been moving their digital communications to private spaces on encrypted messaging apps (EMAs). The popular Meta-owned EMA, WhatsApp, plays an especially important role in everyday communication for Spanish-speaking communities in the U.S. Importantly, the relevance of WhatsApp and EMAs as political communication tools is growing given the prevalence of targeted political mis- and disinformation to Spanish-speaking communities on these apps. This could have damaging effects on our democracy, given that these campaigns often include election-related disinformation. What are the ways in which perceptions of WhatsApp among Mexican-American users affect political communication on the app? In answer to this, I analyze data from 24 semi-structured, in-depth interviews with Mexican-American WhatsApp users in the state of Texas, an emerging battleground state, through the theoretical lens of imagined affordances and media ideologies. I find that WhatsApp users perceive the app as a social space reserved for personal and lighthearted conversations with networks of family and friends. These socially-constructed perceptions dictate communication on the app, and therefore alter the norms by which users engage in political discussions on WhatsApp. Specifically, political content and discussion occurs in the form of humorous or entertaining content, such as memes, to follow these norms. The primary relevance of this finding is that political communication on WhatsApp is not necessarily considered serious or informative, which may allow mis- and dis-information to creep into these closed channels if presented in ways that adhere to these socially-constructed norms. These findings also highlight the ways in which Mexican-American users both share and perceive political information online, which serve as important context for understanding the app’s role in political communication in this community. Thus, I argue that WhatsApp is a necessary tool for political communication among this community, but the social norms instituted by users may provide space for false information to proliferate.
