Effect of four or more prenatal care contacts on healthcare seeking for immediate postpartum complications in Ethiopia: A propensity score matching analysis

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To examine the effect of four or more prenatal care (PNC) contacts on healthcare‐seeking behavior (HSB) for immediate postpartum complications (IPPC) in Ethiopia. Methods We used data from the Performance Monitoring for Action Ethiopia longitudinal surveys of baseline and 6‐week postpartum surveys conducted between 2019 and 2020.

A Joint Test of Unconfoundedness and Common Trends

Journal of Applied Econometrics, EarlyView.
ABSTRACT We introduce an overidentification test of two alternative assumptions to identify the average treatment effect on the treated in a two‐period panel data setting: unconfoundedness and common trends. Under unconfoundedness, treatment assignment and post‐treatment outcomes are independent, conditional on control variables and pre‐treatment ...

Cohesive Motion Control Algorithm for Formation of Multiple Autonomous Agents

Journal of Robotics, 2010
This paper presents a motion control strategy for a rigid and constraint consistent formation that can be modeled by a directed graph whose each vertex represents individual agent kinematics and each of directed edges represents distance constraints ...

Fiscal Policy Regimes in Resource‐Rich Economies

Journal of Applied Econometrics, EarlyView.
ABSTRACT We analyse fiscal policy in resource‐rich economies using a novel Bayesian regime‐switching panel model. The identified regimes capture pro‐ or countercyclical fiscal behaviour by allowing regime‐specific shifts in the average fiscal stance, while the switches between the regimes have the interpretation of changes in fiscal policy.

Heavy Metal Mixture Exposure and Insulin Resistance in U.S. Adults: The Mediating Role of Systemic Inflammation

Journal of Clinical Laboratory Analysis, EarlyView.
In a nationally representative sample of 3042 U.S. adults from NHANES 2021–2023, blood lead, cadmium, and mercury, both individually and as a weighted quantile sum (WQS) mixture, were inversely associated with insulin resistance assessed by HOMA‐IR. Systemic inflammation, measured by high‐sensitivity C‐reactive protein (hs‐CRP), significantly mediated ...

A Min–Max Relation on Dicuts and Dijoins in Weighted Chordal Digraphs

Journal of Graph Theory, EarlyView.
ABSTRACT In a digraph, a dicut is a cut where all the arcs cross in one direction. A dijoin is a subset of arcs that intersects every dicut. Edmonds and Giles conjectured that in a weighted digraph, the minimum weight of a dicut is equal to the maximum size of a packing of dijoins. This has been disproved. However, the unweighted version conjectured by

Scheduling early primary care follow‐up after pneumonia: A retrospective target trial emulation in five hospitals

Journal of Hospital Medicine, EarlyView.
Abstract Background Current guidelines make no recommendations on discharge interventions or scheduling outpatient follow‐up after hospitlization for commnity‐acquired pneumonia (CAP). Objectives To assess the impact of scheduling early primary care follow‐up prior to discharge home among survivors of hypoxemic CAP hospitalizations.
