Reputation Systems Bias In The Platform Workplace, E. Gary Spitko Aug 2020

Reputation Systems Bias In The Platform Workplace, E. Gary Spitko

Faculty Publications

Online reputation systems enable the providers and consumers of a product or service to rate one another and allow others to rely upon those reputation scores in deciding whether to engage with a particular provider or consumer. Reputation systems are an intrinsic feature of the platform workplace, in which a platform operator, such as Uber or TaskRabbit, intermediates between the provider of a service and the consumer of that service. Operators typically rely upon consumer ratings of providers in rewarding and penalizing providers. Thus, these reputation systems allow an operator to achieve enormous scale while maintaining quality control and user …

Noncollinear Enhancement Cavity For Record-High Out-Coupling Efficiency Of An Extreme-Uv Frequency Comb, Chuankun Zhang, Stephen B. Schoun, Christoph M. Heyl, Gil Porat, Mette B. Gaarde, Jun Ye Aug 2020

Noncollinear Enhancement Cavity For Record-High Out-Coupling Efficiency Of An Extreme-Uv Frequency Comb, Chuankun Zhang, Stephen B. Schoun, Christoph M. Heyl, Gil Porat, Mette B. Gaarde, Jun Ye

Faculty Publications

We demonstrate a femtosecond enhancement cavity with a crossed-beam geometry for efficient generation and extraction of extreme-ultraviolet (XUV) frequency combs at a 154 MHz repetition rate. We achieve a record-high out-coupled power of 600 μW, directly usable for spectroscopy, at a wavelength of 97 nm. This corresponds to a >60% out-coupling efficiency. The XUV power scaling and generation efficiency are similar to that achieved with a single Gaussian-mode fundamental beam inside a collinear enhancement cavity. The noncollinear geometry also opens the door for the generation of isolated attosecond pulses at >100 MHz repetition rate.

Cambridge Analytica's Black Box, Margaret Hu

Faculty Publications

The Cambridge Analytica–Facebook scandal led to widespread concern over the methods deployed by Cambridge Analytica to target voters through psychographic profiling algorithms, built upon Facebook user data. The scandal ultimately led to a record-breaking $5 billion penalty imposed upon Facebook by the Federal Trade Commission (FTC) in July 2019. The FTC action, however, has been criticized as failing to adequately address the privacy and other harms emanating from Facebook’s release of approximately 87 million Facebook users’ data, which was exploited without user authorization. This Essay summarizes the FTC’s response to the Cambridge Analytica–Facebook scandal. It concludes that the scandal focuses …

Activity And Regeneration Of Electrodeposited Fe-Ni-Co-Based Electrocatalysts For The Alkaline Oxygen Evolution Reaction, Yujia Zhang, Orhan Kizilkaya, Hubert K. Bilan, Richard Kurtz, Elizabeth J. Podlaha

Faculty Publications

A methodology to recover the oxygen evolution reaction (OER) kinetics of aged, electrodeposited Fe-Ni-Co thin films is presented. The electrodeposits were fabricated galvanostatically onto rotating copper electrodes and contained a small amount of Co. The OER characterized in 1 M KOH was a function of the deposit composition. The Tafel slope and the overpotential at 10 mA/cm2 observed with ohmically corrected linear sweep voltammetry were both a function of the deposit metal ratio, Fe/(Ni + Co), with the lowest values occurring at a ratio of 1.2. An Fe-rich deposit was purposely altered upon aging to degrade the OER kinetics. The …

List-Wise Fairness Criterion For Point Processes, Jin Shang, Mingxuan Sun, Nina S.N. Lam Aug 2020

List-Wise Fairness Criterion For Point Processes, Jin Shang, Mingxuan Sun, Nina S.N. Lam

Faculty Publications

Many types of event sequence data exhibit triggering and clustering properties in space and time. Point processes are widely used in modeling such event data with applications such as predictive policing and disaster event forecasting. Although current algorithms can achieve significant event prediction accuracy, the historic data or the self-excitation property can introduce biased prediction. For example, hotspots ranked by event hazard rates can make the visibility of a disadvantaged group (e.g., racial minorities or the communities of lower social economic status) more apparent. Existing methods have explored ways to achieve parity between the groups by penalizing the objective function …

Faculty Publications

Copyright © 2020 American Chemical Society. Sodium chloride (NaCl) is a very common molecule in biotic and abiotic aqueous environments. In both cases, variation of ionic strength is inevitable. In addition to the osmotic variation posed by such perturbations, the question of whether the interactions of monovalent ions Na+ and Cl-, especially with the neutral head groups of phospholipid membranes are impactful enough to change the membrane rigidity, is still not entirely understood. We investigated the dynamics of 1,2-di-(octadecenoyl)-sn-glycero-3-phosphocholine (DOPC) vesicles with zwitterionic neutral head groups in the fluid phase with increasing external salt concentration. At higher salt concentrations, we …

Faculty Publications

Introduced in the literature in 1913 by Bergius, who at the time was studying biomass coalification, hydrothermal carbonisation, as many other technologies based on renewables, was forgotten during the "industrial revolution". It was rediscovered back in 2005, on the one hand, to follow the trend set by Bergius of biomass to coal conversion for decentralised energy generation, and on the other hand as a novel green method to prepare advanced carbon materials and chemicals from biomass in water, at mild temperature, for energy storage and conversion and environmental protection. In this review, we will present an overview on the latest …

Sociopolitical Silos: Environmental Views And The Multiplicative Effect Of Same-Party Friends, Lawrence C. Hamilton, Joel Hartter, Curt Grimm Aug 2020

Sociopolitical Silos: Environmental Views And The Multiplicative Effect Of Same-Party Friends, Lawrence C. Hamilton, Joel Hartter, Curt Grimm

Faculty Publications

Analysis of climate and other environmental questions on three regional survey projects conducted over 2017–2020 (9,000+ interviews) elaborate on the well-known importance of political factors by adding support for three newer propositions. First, strength of political identification predicts climate-change views within the ranks of conservatives but not within ranks of liberals, evidence that conservatives’ climate-change views are more politically determined. Second, factor analysis suggests that climate-change beliefs meet statistical criteria for being an indicator of sociopolitical identity, alongside the traditional indicators of ideology and party, or the newer one of Trump support. This result calls for caution interpreting models that …

The Longitudinal Associations Of Sound Financial Management Behaviors And Marital Quality, Jeffrey P. Dew Aug 2020

The Longitudinal Associations Of Sound Financial Management Behaviors And Marital Quality, Jeffrey P. Dew

Faculty Publications

We investigated the association between sound financial management behaviors and marital quality, particularly the direction of the association and a potential mediator. To do this, we used three waves of longitudinal dyadic data that spanned three years from 279 married couples living in a large northwestern city and a longitudinal path analysis that incorporated the Actor-Partner Interdependence Model (Kenny et al. Dyadic data analysis. Guilford, New York City, 2006). Marital satisfaction at T1 was positively associated with sound financial management behavior for husbands; we only found actor effects, though. Wives’ T2 reports of sound financial management behavior were directly and …

Residual-Based Multi-Filter Methodology For All-Source Fault Detection, Exclusion, And Performance Monitoring, Juan Jurado, John F. Raquet, Christine M. Schubert Kabban Air Force Institute Of Technology, Jonathon S. Gipson

Faculty Publications

All-source navigation has become increasingly relevant over the past decade with the development of viable alternative sensor technologies. However, as the number and type of sensors informing a system increases, so does the probability of corrupting the system with sensor modeling errors, signal interference, and undetected faults. Though the latter of these has been extensively researched, the majority of existing approaches have constrained faults to biases and designed algorithms centered around the assumption of simultaneously redundant, synchronous sensors with valid measurement models, none of which are guaranteed for all-source systems. As part of an overall all-source assured or resilient navigation …

The Invisible Message, Andrew S. Gibbons Iii, Elizabeth Boling Aug 2020

The Invisible Message, Andrew S. Gibbons Iii, Elizabeth Boling

Faculty Publications

The number and variety of messages conveyed by an instructional experience is astonishing, but most designers are unaware of their number, subtlety, and impact. Many of those messages they would not choose to send if they recognized their existence in practice. The design of invisible and abstract message structures receives less attention from designers today than those parts of the design given to more vivid, colorful, and showy surface structures. Invisible message structures work behind the scenes to produce the smooth surface performances in front of the curtain; they are seldom seen directly, but their power is indisputable. The purpose …
