“Big River People”: Human-Nature Interactions In The Mekong And Columbia River Basins, Andrew M. Stone

Forest and Society

The Mekong and Columbia Rivers are a world apart. Yet rivers instantiate and manifest critical ecological relations. This paper draws on qualitative interviews, community dialogues, historical documents, and ceremony-based encounters to examine political practices among "big river people'' in the Mekong and Columbia River basins. It interprets participants' narratives and actions as expressions of ontological politics, i.e., contestation of imposed realities and lifeways. Participants link environmental degradation to violations of relational ethics. Across both study groups, elders and knowledge holders describe ecological and cultural loss as forms of ongoing violence enacted through hydropower development, displacement, and resulting erasure of ways …

Distinguishing Drought Experiences: From Perception To Measurement And Their Significance On Productivity Value In Uganda, Parisa Pakrooh, Fabio Gaetano Santeramo, Giuseppe Maggio

Fondazione Eni Enrico Mattei Working Papers

Weather shocks increasingly threaten agricultural productivity in Sub-Saharan Africa. While the negative effects of drought on production have been documented in numerous studies, the behavioral dimension of adaptation, particularly how households perceive drought and what shapes these perceptions, remains less explored. The study focuses on Uganda to distinguish between self-reported drought (subjective) and data-driven drought (objective) and how their divergence is associated with agricultural outcomes. The study relies on four waves of household surveys (UNPS for 2009/10, 2010/11, 2011/12, and 2013/14) with historical re-analysis data on temperature and precipitation from 1981 to 2015.

The Impact Of Mnar Attrition On Estimation Of Latent Growth Curve Models With Binary Observed Variables, Jason T. Newsom, Brian T. Keller, Mallory R. Kroeck, Nicholas A. Smith

Psychology Faculty Publications and Presentations

A Monte Carlo simulation was used to evaluate the performance of latent growth curve (LGC) modelswith binary observed variables when the attrition pattern was missing not at random (MNAR) for fivetime points. Parameter and standard error biases for three estimation methods were compared:weighted least squares with mean and variance adjustment (WLSMV), categorical robust marginal max-imum likelihood (categorical MLR), and Bayes. The results indicated that robust diagonal weightedleast squares paired with multiple imputation (MI) performed best when values were missing at ran-dom. When data were missing not at random, Bayesian estimates performed best.
