title: Enzymatic Synthesis of Maltodextrin Fatty Acid Esters and their Emulsion Stabilizing and Microbial Inhibitory Properties
Creators: name: Park, Namhyeon
Publisher: name: Utah State University
Year: 2021

description: Food additives have been one of the traditional methods for preserving foods and are still in everyday use for multiple reasons. As the market size of processed foods grows, the use of food additives is increasing. Simultaneously, consumers try to avoid specific food additives or demand less processed foods because of several potential health concerns, suggesting the need for safe food additives.
In this environment, one group of food additives consisting of carbohydrates and fatty acids have received attention because of its nontoxicity and biodegradability with diverse functions. Notably, carbohydrate fatty acid compounds made of sucrose have been approved and used in the food industry. However, because of a relatively large ratio of low water-soluble fatty acid to sucrose, most of these compounds have demonstrated poor water solubility, leading to limited application.
Maltodextrin is produced by the breakdown of starch and consists of many smaller units which are water-soluble. This product was selected to attach to fatty acids and led to good water solubility. In addition, maltodextrin attached to fatty acids stabilized the immiscible mixture of oil and water not to be separated and inhibited multiple food-spoilage or poisoning microorganisms in lab and food models.This compound also showed low intestinal toxicity.
Maltodextrin attached to fatty acids appears to be a food additive that can decrease the potential health risks of food products while maintaining the food quality by stabilizing the food system and/or preventing microbial contamination.

Modeling the Retention Probability of Black Holes in Globular Clusters: Kicks and Rates
Creators: name: Moody, Kenneth

Publisher: name: arXiv
Year: 2008

description: We simulate black hole binary interactions to examine the probability of mergers and black hole growth and gravitational radiation signals using a specific initial distribution of masses for black holes in globular clusters and a simple semi-analytic formalism for dynamical interactions. We include 3-body recoil and the latest results in numerical relativity for gravitational radiation recoil. It is found that while 99% of binaries are ejected from low metallicity, low mass clusters; metal rich massive clusters retain 5% of their binaries. An interesting fraction of the ejected binaries, especially those from high mass, high metallicity systems, merge on timescales short enough to be gravitational radiation sources during their mergers with rates approaching those expected for galactic field black hole binaries. While the merger rates are comparable, the much larger mass of these binaries and their localization will make them appealing targets for advanced LIGO. We single out two possible Milky Way clusters (NGC 6441 and NGC 6388) as having the properties for a good probability of retention.

description: Let $(X_{n,i})_{1\le i\le n,n\in\mathbb{N}}$ be a triangular array of row-wise stationary $\mathbb{R}^d$-valued random variables. We use a "blocks method" to define clusters of extreme values: the rows of $(X_{n,i})$ are divided into $m_n$ blocks $(Y_{n,j})$, and if a block contains at least one extreme value, the block is considered to contain a cluster. The cluster starts at the first extreme value in the block and ends at the last one. The main results are uniform central limit theorems for empirical processes $Z_n(f):=\frac{1}{\sqrt {nv_n}}\sum_{j=1}^{m_n}(f(Y_{n,j})-Ef(Y_{n,j})),$ for $v_n=P\{X_{n,i}\neq0\}$ and $f$ belonging to classes of cluster functionals, that is, functions of the blocks $Y_{n,j}$ which only depend on the cluster values and which are equal to 0 if $Y_{n,j}$ does not contain a cluster. Conditions for finite-dimensional convergence include $β$-mixing, suitable Lindeberg conditions and convergence of covariances. To obtain full uniform convergence, we use either "bracketing entropy" or bounds on covering numbers with respect to a random semi-metric. The latter makes it possible to bring the powerful Vapnik--Červonenkis theory to bear. Applications include multivariate tail empirical processes and empirical processes of cluster values and of order statistics in clusters. Although our main field of applications is the analysis of extreme values, the theory can be applied more generally to rare events occurring, for example, in nonparametric curve estimation.

description: Clothing changes and lack of data labels are both crucial challenges in person ReID. For the former challenge, people may occur multiple times at different locations wearing different clothing. However, most of the current person ReID research works focus on the benchmarks in which a person's clothing is kept the same all the time. For the last challenge, some researchers try to make model learn information from a labeled dataset as a source to an unlabeled dataset. Whereas purely unsupervised training is less used. In this paper, we aim to solve both problems at the same time. We design a novel unsupervised model, Sync-Person-Cloud ReID, to solve the unsupervised clothing change person ReID problem. We developer a purely unsupervised clothing change person ReID pipeline with person sync augmentation operation and same person feature restriction. The person sync augmentation is to supply additional same person resources. These same person's resources can be used as part supervised input by same person feature restriction. The extensive experiments on clothing change ReID datasets show the out-performance of our methods.

title: Induction and Initial Characterization of Male-Sterile Mutants on the Second Chromosome of Drosophila melanogaster
Creators: name: Graves, Susan M.
Publisher: name: Utah State University
Year: 1972

description: Fourteen recessive, male-sterile, autosomal mutants of Drosophila melanogaster were induced using ethyl methanesulfonate. The techniques employed restricted the recovery of mutants to those located on the second chromosome. Eleven of the mutants were male-sterile at 23°C, and the remaining three, though fertile at 23°C, were male-sterile at 28°C. Complementation tests involving all possible pairs of mutations showed each to be located in a unique cistron.
Spermiogenesis in each mutant was studied by light microscopy to determine the stage at which cellular differentiation deviates from normal and to characterize the associated gross abnormalities. Phase contrast microscopy showed that each mutant sterile at 23°C could be placed in one of four major categories: (I) premeiotic, (II) motile sperm with elongate heads, (III) non-motile sperm with elongate heads, or (IV) non-motile sperm with non-elongate heads.
Examination of each temperature-sensitive male-sterile mutant raised at 23°C and 25°C revealed the presence of motile sperm with elongate heads. No observations were made of male homozygotes raised at the restrictive temperature.

We fully characterize the set of fixed points for both models. They are identical. Further on, we present reformulations of both models on the more general level of densities of agents in the opinion space as interactive Markov chains. We also characterize the sets of fixed points as identical in both models.

title: A Study of 5-Fluorouracil: Its Effects and Mode of Action in Drosophila melanogaster
Creators: name: Jenkins, John B.
Publisher: name: Utah State University
Year: 1965

description: Investigations involving the fluorinated pyrimidine, 5-fluorouracil, and its effects on viruses, bacteria, plants and mammals, have brought to light the following facts: FU inhibits the growth of bacteria, plants and mammalian cells and it decreases the ability of certain viruses to produce progeny. In other words, FU is an antimetabolite that inhibits growth and/or reproduction. Two mechanisms have emerged from these studies to define the mode of action of FU. The first mechanism involves the incorporation of the compound into the RNA of the organism thus altering the base sequence and creating a non functional or damaging nucleic acid. The second mechanism concerns the blockage of the methylating enzyme, thymidylate synthetase, which catalyzes the reaction converting dUMP to TMP. When this enzyme is blocked it would, of course, follow that DNA synthesis would be inhibited. FU has not been shown to be incorporated into DNA but 5-trifluoromethyluracil has (Gottschling and Heidelberger, 1963).
No work has been done with FU and its effects on Drosophila but some work has been done with its biological effects on the housefly, Musca domestica (Kilgore and Painter, 1962). In Musca, FU was very toxic when fed in the diet. When 5-FU-2-14C was ingested, it was found that almost all of the compound was passed out in the excreta as waste product. Some 14C, however, was incorporated into the egg, either as FU or one of its metabolic products. An inverse relationship exlsted between the amount of 14C in the egg and hatchability. To account for the lethality it has been proposed (Kilgore, personal communication) that the FU is incorporated into the nucleic acids, specifically RNA, producing a non functional nucleic acid.
In preliminary investigations with FU and its biological effects on Drosophila, it was noted that the compound had a pronounced lethal effect. As was noted earlier, two main possibilities exist to explain this lethal effect in Drosophila and it is the purpose of this investigation to examine those possibilities.
Nonlinearity-induced transition in nonlinear Su-Schrieffer-Heeger model and nonlinear higher-order topological system

description: We study the topological physics in nonlinear Schrödinger systems on lattices. We employ the quench dynamics to explore the phase diagram, where a pulse is given to a lattice point and we analyze its time evolution. There are two system parameters $λ$ and $ξ$, where $λ$ controls the hoppings between the neighboring links and $ξ$ controls the nonlinearity. The dynamics crucially depends on these system parameters. Based on analytical and numerical studies, we derive the phase diagram of the nonlinear Su-Schrieffer-Heeger (SSH) model in the ($λ,ξ$) plane. It consists of four phases. The topological and trivial phases emerge when the nonlinearity $ξ$ is small. The nonlinearity-induced localization phase emerges when $ξ$ is large. We also find a dimer phase as a result of a cooperation between the hopping and nonlinear terms. A similar analysis is made of the nonlinear second-order topological system on the breathing Kagome lattice, where a trimer phase appears instead of the dimer phase.

description: Recent years have witnessed a great interest in orbital related electronics (also termed as orbitronics). In the current work, we present a first-principles density functional theory calculation on the orbital magnetic moments, intrinsic orbital Hall effect, and ordinary magnetoconductivity effects in rhombohedral graphene multilayers. Our calculations suggest a giant orbital moment that arises from inter-atomic cycloid motion, reaching over 30 muB under an intermediate gate voltage. This leads to a valley polarization under an external magnetic field, as observed in recent experiments [Nature 623, 41-47 (2023)]. In addition, the orbital-related transport feature exhibit significant responses that are potentially observed in experiments. We also suggest that under a periodic field driven (such as high frequency light field), the ungated graphene multilayers could host strong quantum anomalous and orbital Hall effects, engineered by the layer number. As the graphene multilayers are intrinsically nonmagnetic with negligible spin-orbit coupling, the orbital moments would not be entangled by spin-related signals. Thus, they serve as an ideal platform to conduct orbitronic measurements and utilization for next generation information read/write nanodevices.

Unraveling phase transformation with phononic hyperbolicity using off-resonant terahertz light

description: Noncontacting and nondestructive control of geometric phase in conventional semiconductors plays a pivotal role in various applications. In the current work, we present a theoretical and computational investigation on terahertz (THz) light-induced phase transformation of conventional binary semiconducting compounds among different structures including rock-salt, zinc-blende, wurtzite, and hexagonal phases. Using MgS and MgSe as prototypical examples, we perform anharmonic phonon mediated calculations and reveal large contrasting lattice contributed dielectric susceptibility in the THz regime. We then construct a THz-induced phase diagram under intermediate temperature and reveal rock-salt to hexagonal and then wurtzite structure transformations with increasing light intensity. This does not require a high temperature environment as observed in traditional experiments. The low energy barrier suggests that the phase transition kinetics can be fast, and the stable room temperature phonon dispersions guarantee their non-volatile nature. Furthermore, we disclose the phononic hyperbolicity with strong anisotropic THz susceptibility components, which serves as a natural hyperbolic material with negative refractive index. Our work suggests the potential to realize metastable hidden phases using noninvasive THz irradiation, which expands the conventional pressure-temperature ($P-T$) phase diagram by adding light as an additional control factor.

description: The present work proposes a new formalism for the inner regions of a neutrino-dominated accretion flows (NDAFs) by considering the self-gravity, where the neutrino opacity is high enough to make neutrinos trapped becoming a dominant factor in the transportation of energy and angular momentum over the magneto rotational instability. We investigate the possibility of gravitational instability and fragmentation to model the highly variable structure of the prompt emission in gamma-ray bursts (GRBs). The results lead us to introduce the gravitational instability, in these inner regions, as a source of a new viscosity which is of the same functional form as that of the $β$-prescription of viscosity. Such a consideration brings about fragmentation in the unstable inner disk. In addition, we find the consequent clumpy structure of this area capable to account for the temporal variability of GRB's light curve, especially for the lower choices of the parameter $β$, $\sim 10^{-5}$. Finally, we predict the formation of gravitational waves through the migration of fragments before being tidally disrupted. These waves appear to be detectable via a range of current and future detectors from LIGO to Cosmic Explorer.

Spin-S Kitaev model: Classical Ground States, Order by Disorder and Exact Correlation Functions

description: In the first part of this paper, we study the spin-S Kitaev model using spin wave theory. We discover a remarkable geometry of the minimum energy surface in the N-spin space. The classical ground states, called Cartesian or CN-ground states, whose number grows exponentially with the number of spins N, form a set of points in the N-spin space. These points are connected by a network of flat valleys in the N-spin space, giving rise to a continuous family of classical ground states. Further, the CN-ground states have a correspondence with dimer coverings and with self avoiding walks on a honeycomb lattice. The zero point energy of our spin wave theory picks out a subset from a continuous family of classically degenerate states as the quantum ground states; the number of these states also grows exponentially with N. In the second part, we present some exact results. For arbitrary spin-S, we show that localized Z_2 flux excitations are present by constructing plaquette operators with eigenvalues \pm 1 which commute with the Hamiltonian. This set of commuting plaquette operators leads to an exact vanishing of the spin-spin correlation functions, beyond nearest neighbor separation, found earlier for the spin-1/2 model [G. Baskaran, S. Mandal and R. Shankar, Phys. Rev. Lett. 98, 247201 (2007)]. We introduce a generalized Jordan-Wigner transformation for the case of general spin-S, and find a complete set of commuting link operators, similar to the spin-1/2 model, thereby making the Z_2 gauge structure more manifest. The Jordan-Wigner construction also leads, in a natural fashion, to Majorana fermion operators for half-integer spin cases and hard-core boson operators for integer spin cases, strongly suggesting the presence of Majorana fermion and boson excitations in the respective low energy sectors.

description: The nonlinear Hall effect, which is the second-order harmonic charge Hall effect from the Berry curvature dipole in momentum space, has received much attention recently. As the responses to higher harmonics of the driving ac electric field are prominent and measurable, we develop a general nonlinear theory by taking the charge and spin currents as well as the longitudinal and transverse effects into account. We introduce the expansion order of the electric field and Berry curvature multipole moment, where the Berry curvature dipole is a particular one manifesting itself at the second harmonic order and the second expansion order of the electric field. There are four cases with conserving or breaking the time-reversal symmetry (TRS) and inversion symmetry (IS). We find a specific ``selection rule" that only longitudinal odd harmonic order charge currents exist for conserving both the TRS and IS, and with breaking both symmetries, all harmonic order charge and spin currents are nonzero. With conserving TRS and breaking IS, the charge Hall current exists at even harmonic order, and the longitudinal charge current occurs at odd harmonic order. Only the longitudinal spin current survives at even harmonic order. With breaking TRS and conserving IS, only odd harmonic order charge and spin currents can appear. Moreover, we observe that every harmonic order current contains a series of infinite-order expansion of the electric field. We further show that the Berry curvature dipole and quadrupole can be determined by measuring the second and fourth harmonic order currents in experiments. This may open a way to explore the higher responses of an ac driving system.

description: The realization of the quantum anomalous Hall (QAH) effect without magnetic doping attracts intensive interest since magnetically doped topological insulators usually possess inhomogeneity of ferromagnetic order. Here, we propose a different strategy to realize intriguing QAH states arising from the interplay of light and non-magnetic disorder in two-dimensional topologically trivial systems. By combining the Born approximation and Floquet theory, we show that a time-reversal invariant disorder-induced topological insulator, known as the topological Anderson insulator (TAI), would evolve into a time-reversal broken TAI and then into a QAH insulator by shining circularly polarized light. We utilize spin and charge Hall conductivities, which can be measured in experiments directly, to distinguish these three different topological phases. This work not only offers an exciting opportunity to realize the high-temperature QAH effect without magnetic orders, but also is important for applications of topological states to spintronics.

description: We present optical spectropolarimetric observations of Type Ic supernova (SN) 2007gr with Subaru telescope at 21 days after the maximum brightness (~37 days after the explosion). Non-zero polarization as high as ~3% is observed at the absorption feature of Ca II IR triplet. The polarization of the continuum light is ~0.5% if we estimate the interstellar polarization (ISP) component assuming that the continuum polarization has a single polarization angle. This suggests that the axis ratio of the SN photosphere projected to the sky is different from unity by ~10%. The polarization angle at the Ca II absorption is almost aligned to that of the continuum light. These features may be understood by the model where a bipolar explosion with an oblate photosphere is viewed from the slightly off-axis direction and explosively synthesized Ca near the polar region obscures the light originated around the minor axis of the SN photosphere. Given the uncertainty of the ISP, however, the polarization data could also be interpreted by the model with an almost spherically symmetric photosphere and a clumpy Ca II distribution.

description: A manifold obtained by k simultaneous symplectic blow-ups of CP^2 of equal sizes epsilon (where the size of CP^1 in CP^2 is one) admits an effective two-dimensional torus action if k <= 3. We show that it does not admit such an action if k >=4 and epsilon <= 1/(3k 2^{2k}). For the proof, we correspond between the geometry of a symplectic toric four-manifold and the combinatorics of its moment map image. We also use techniques from the theory of J-holomorphic curves.
Spectral-line performance of low-frequency radio telescope arrays: SKA-Low stations

Publisher: name: arXiv
Year: 2025
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: The effects of diffraction, reflection and mutual coupling on the spectral smoothness of radio telescopes becomes increasingly important at low frequencies, where the observing wavelength may be significant compared with the antenna or array dimensions. These effects are important for both traditional parabolic antennas, which are prone to the 'standing wave' phenomenon caused by interference between direct and scattered wavefronts, and aperture arrays, such as the SKA-Low, MWA, HERA, and LOFAR which have more complicated scattering geometries and added dependence on pointing direction (scan angle). Electromagnetic modelling of these effects is computationally intensive and often only possible at coarse frequency resolution. Therefore, using the example of SKA-Low station configurations, we investigate the feasibility of parameterising scattering matrices, and separating antenna and array contributions to telescope chromaticity. This allows deeper insights into the effect on spectral smoothness and frequency-dependent beam patterns of differing antenna configurations. Even for the complicated SKA-Low element design, band-limited delay-space techniques appear to produce similar results to brute-force electromagnetic models, and allow for faster computation of station beam hypercubes (position, frequency and polarisation-dependent point spread functions) at arbitrary spectral resolution. As such techniques could facilitate improvements in the design of low-frequency spectral-line surveys, we conduct a simulated Cosmic Dawn experiment using different observing techniques and station configurations.

description: We present a theory for spin selective Aharonov-Bohm oscillations in a lateral triple quantum dot. We show that to understand the Aharonov-Bohm (AB) effect in an interacting electron system within a triple quantum dot molecule (TQD) where the dots lie in a ring configuration requires one to not only consider electron charge but also spin. Using a Hubbard model supported by microscopic calculations we show that, by localizing a single electron spin in one of the dots, the current through the TQD molecule depends not only on the flux but also on the relative orientation of the spin of the incoming and localized electrons. AB oscillations are predicted only for the spin singlet electron complex resulting in a magnetic field tunable "spin valve".

description: Starting from experimental studies on alpha-clustering in excited self-conjugate nuclei (from $^{16}$O to $^{28}$Si), temperature and density conditions for such a clustering are determined. Measured temperatures have been found in the range of 5.5 - 6.0 MeV whereas density values of 0.3 - 0.4 times the saturation density are deduced, i.e., 0.046 to 0.062 $fm^{-3}$. Such a density domain is also predicted by constrained self-consistent mean field calculations. These results constitute a benchmark for alpha clustering from self-conjugate nuclei in relation to descriptions of stellar evolution and supernovae.

Essays on Gender Differences in Sponsorship and Hiring Decisions
Creators: name: Campbell, Elizabeth Lauren
Publisher: name: Carnegie Mellon University
Year: 2021
Subjects: Organizational Behavioral Psychology

description: Despite considerable progress toward equality in society, gender differences persist in career trajectories. Women ascend organizational hierarchies at slower rates and remain underrepresented in toptier leadership positions and elite occupations, compared to men (e.g., Catalyst, 2020; Fernandez-Mateo & King, 2011; Petersen & Morgan, 1995). In effort to understand how gender inequity in career advancement is created and reproduced, this dissertation examines evaluations and decision-making processes in hiring and sponsorship. Sponsorship is a form of career support in which high-status and influential senior colleagues (i.e., sponsors) leverage their social capital to secure career opportunities that facilitate the upward mobility of junior employees. Examples include job referrals, recommendations, advocacy for promotions, and informal support like strategic introductions or discussing junior employees’ achievements to other influential members of the firm (Ibarra et al., 2010). These processes are tested using quantitative and qualitative methodologies across three independent research papers.

description: Research indicates that error detection is enhanced in individuals who are highly motivated to avoid errors. As a measure of error processing we focus on Post-Error Slowing (PES), which is the difference in reaction time after an error and after a correct trial. We postulate that neuroticism and negative incentive have an influence on PES.
Globular cluster candidates in the Sagittarius dwarf galaxy

description: Recently, new Sagittarius (Sgr) dwarf galaxy globular clusters were discovered, which opens the question on the actual size of the Sgr globular cluster population, and therefore on our understanding of the Sgr galaxy formation and accretion history onto the Milky Way. Based on Gaia EDR3 and SDSS IV DR16 (APOGEE-2) data sets, we performed an analysis of the color-magnitude diagrams (CMDs) of the eight new Sgr globular clusters found by from a sound cleaning of the contamination of Milky Way and Sgr field stars, complemented by Minniti et al. (2021b) available kinematic and metal abundance information. The cleaned CMDs and spatial stellar distributions reveal the presence of stars with a wide range of cluster membership probabilities. Minni 332 turned out to be a younger (< 9 Gyr) and more metal-rich ([M/H] > -1.0 dex) globular cluster than M54, the nuclear Sgr globular cluster, as could also be the case of Minni 342, 348, and 349, although their results are less convincing. Minni 341 could be an open cluster candidate (age < 1 Gyr, [M/H] ~ -0.3 dex), while the analyses of Minni 335, 343, and 344 did not allow us to confirm their physical reality. We also built the Sgr cluster frequency (CF) using available ages of the Sgr globular clusters and compared it with that obtained from the Sgr star formation history. Both CFs are in excellent agreement. However, the addition of eight new globular clusters with ages and metallicities distributed according to the Sgr age-metallicity relationship turns out in a remarkably different CF.

description: Compared to current single-standard radio solutions, multi-standard radio transceivers enable higher integration, backward compatibility and save power, area and cost. The primary bottleneck in their realization is the development of high-performance frequency-reconfigurable RF circuits. To that end, this research introduces several CMOS-integrated, transformer-based reconfigurable circuit techniques whose effectiveness is validated through measurements of designed transceiver front-end low-noise (LNA) and power amplifier (PA) prototypes. In the first part, the use of high figure-of-merit phase-change (PC) based RF switches in the reconfiguration of CMOS LNAs in the receiver front-end is proposed. The first reported demonstration of an integrated, PC-switch based, dual-band (3/5 GHz) reconfigurable CMOS LNA with transformer source degeneration and designed in a 0.13 μm process is presented. In the second part, a frequency-reconfigurable CMOS transformer combiner is introduced that can be reconfigured to have similar efficiencies at widely separated frequency bands. A 65-nm CMOS triple-band (2.5/3/3.5 GHz) PA employing the reconfigurable combiner was designed. In the final part of this work, the use of transformer coupled-resonators in mm-wave LNA designs for 28 GHz bands was investigated. To cover contiguous and/or widely-separated narrowband channels of the emerging 5G standards, a 65-nm CMOS 24.9-32.7 GHz wideband multi-mode LNA using one-port transformer coupled-resonators was designed. Finally, a 25.1-27.6 GHz tunable-narrowband digitally-calibrated merged LNA-vector modulator design employing transformer coupled-resonators is presented that proposes a compact, differential quadrature generation scheme for phased-array architectures.
Computational Perspectives on Democracy

description: Democracy is a natural approach to large-scale decision-making that allows people affected by a potential decision to provide input about the outcome. However, modern implementations of democracy are based on outdated information technology and must adapt to the changing technological landscape. This thesis explores the relationship between computer science and democracy,which is, crucially, a two-way street—just as principles from computer science can be used to analyze and design democratic paradigms, ideas from democracy can be used to solve hard problems in computer science. Question 1: What can computer science do for democracy? To explore this first question, we examine the theoretical foundations ofthree democratic paradigms: liquid democracy, participatory budgeting, and multiwinner elections. Each of these paradigms broadly redistributes power from the few to the many: For instance, liquid democracy allows people tochoose delegates more flexibly and participatory budgeting enables citizens to directly influence government spending toward public projects. However, because these paradigms are relatively new, their theoretical properties are relativelyunexplored. We analyze each of these three settings from the point of view of computational social choice, which is a mathematical framework for collective decision-making. In particular, we focus on a combination of robustness,fairness, and efficiency with the end goal of providing actionable advice for future iterations of these paradigms.Question 2: What can democracy do for computer science?Toward this end, we explore two settings in which democratic principles can be used to augment approaches to making difficult decisions—in our case, automating ethical decision-making and hiring in online labor markets. Bothof these problems are difficult in the sense that there is no universally agreed upon function to optimize, making them a poor fit for traditional approaches in computer science. Instead, we try to emulate a world in which we can getinput from people in order to arrive at a “societal” decision. In each of these settings, we first propose and analyze a theoretical approach that leads a single decision, and then, in collaboration with HCI researchers, run experiments inthe real world to test the efficacy and practicability of our approaches in the real world.
