A class of directed acyclic graphs with mixed data types in mediation analysis
Canadian Journal of Statistics, Volume 53, Issue 4, December 2025.Abstract We propose a unified class of generalized structural equation models (GSEMs) with data of mixed types in mediation analysis, including continuous, categorical, and count variables. Such models extend substantially the classical linear structural equation model to accommodate many data types arising from the application of mediation analysis ...

Economic Restructuring and Total Factor Productivity Growth: Tunisia Over the Period 1983-2001 [PDF]
In this paper we aim to measure and decompose the growth of frontier total factor productivity (TFP) in Tunisia over the period 1983-2001. We define frontier TFP growth as the shift of the economy’s production frontier, which we obtain by solving for ...

Surface currents and slope selection in crystal growth [PDF]
, 2006 We face the problem to determine the slope dependent current during the epitaxial growth process of a crystal surface. This current is proportional to delta=(p+) + (p-), where (p+/-) are the probabilities for an atom landing on a terrace to attach to the

Irrigation and Drainage, Volume 74, Issue 5, Page 1874-1888, December 2025.ABSTRACT Soybean growth, yield, crop evapotranspiration (ETc) and crop water use efficiency (CWUE or crop water productivity, CWP) under different irrigation levels in three different soil types in the same field were investigated concurrently. Treatments in each soil type were: (i) variable rate irrigation (VRI), (ii) fixed rate full irrigation (FR‐1″)

Earth's Future, Volume 13, Issue 12, December 2025.Abstract Bivalve mollusks are vital to coastal economies and food security, yet the impact of ocean warming and acidification on aquaculture remains unclear due to a lack of ground truth data on future production. Most experimental studies rely on short‐term, single‐factor experiments in stable and food‐unlimited environments, making it difficult to ...

Too much consensus could be harmful : measuring the degree of implementation of the Washington consensus and its impact on economic growth [PDF]
In this paper, we construct a unique quantitative measure of the depth and pace of all aspects of IFI programs — the Washington consensus index (WCI), and we investigate their whole impact on economic growth. Two main conclusions emerge.
