How Do Fairness Definitions Fare? Examining Public Attitudes Towards Algorithmic Definitions of Fairness
What is the best way to define algorithmic fairness? While many definitions
of fairness have been proposed in the computer science literature, there is no
clear agreement over a particular definition. In this work, we investigate
ordinary people's perceptions of three of these fairness definitions. Across
two online experiments, we test which definitions people perceive to be the
fairest in the context of loan decisions, and whether fairness perceptions
change with the addition of sensitive information (i.e., race of the loan
applicants). Overall, one definition (calibrated fairness) tends to be more
preferred than the others, and the results also provide support for the
principle of affirmative action.Comment: To appear at AI Ethics and Society (AIES) 201

Housing Justice in Unequal Cities
Housing Justice in Unequal Cities is a global research network funded by the National Science Foundation (BCS 1758774) and housed at the Institute on Inequality and Democracy at UCLA Luskin. This open-access volume, co-edited by Ananya Roy and Hilary Malson, brings together movement-based and university-based scholars to build a shared field of inquiry focused on housing justice. Based on a convening that took place in Los Angeles in January 2019, at the LA Community Action Network and at the University of California, Los Angeles, the essays and interventions situate housing justice in the long struggle for freedom on stolen land. Embedded in the stark inequalities of Los Angeles, our work is necessarily global, connecting the city’s Skid Row to the indebted and evicted in Spain and Greece, to black women’s resistance in Brazil, to the rights asserted by squatters in India and South Africa. Learning from radical social movements, we argue that housing justice also requires a commitment to research justice. With this in mind, our effort to build a field of inquiry is also necessarily an endeavor to build epistemologies and methodologies that are accountable to communities that are on the frontlines of banishment and displacement
Causal complexity demands community coordination
Yarkoni’s argument risks skepticism about the very possibility of social science: If social phenomena are too causally complex, normal scientific methods could not possibly untangle them. We argue that the problem of causal complexity is best approached at the level of scientific communities and institutions, not the modeling practices of individual scientists
Pulmonary Artery Catheter Use and Mortality in the Cardiac Intensive Care Unit.
BACKGROUND: The appropriate use of pulmonary artery catheters (PACs) in critically ill cardiac patients remains debated.
OBJECTIVES: The authors aimed to characterize the current use of PACs in cardiac intensive care units (CICUs) with attention to patient-level and institutional factors influencing their application and explore the association with in-hospital mortality.
METHODS: The Critical Care Cardiology Trials Network is a multicenter network of CICUs in North America. Between 2017 and 2021, participating centers contributed annual 2-month snapshots of consecutive CICU admissions. Admission diagnoses, clinical and demographic data, use of PACs, and in-hospital mortality were captured.
RESULTS: Among 13,618 admissions at 34 sites, 3,827 were diagnosed with shock, with 2,583 of cardiogenic etiology. The use of mechanical circulatory support and heart failure were the patient-level factors most strongly associated with a greater likelihood of the use of a PAC (OR: 5.99 [95% CI: 5.15-6.98]; P \u3c 0.001 and OR: 3.33 [95% CI: 2.91-3.81]; P \u3c 0.001, respectively). The proportion of shock admissions with a PAC varied significantly by study center ranging from 8% to 73%. In analyses adjusted for factors associated with their placement, PAC use was associated with lower mortality in all shock patients admitted to a CICU (OR: 0.79 [95% CI: 0.66-0.96]; P = 0.017).
CONCLUSIONS: There is wide variation in the use of PACs that is not fully explained by patient level-factors and appears driven in part by institutional tendency. PAC use was associated with higher survival in cardiac patients with shock presenting to CICUs. Randomized trials are needed to guide the appropriate use of PACs in cardiac critical care
