Hyperspectral species maps and LiDAR‐based structured population models show future forest fire frequency may compromise forest resilience

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring forest recovery from disturbances at scale requires tracking tree dynamics, yet traditional ground‐based approaches are resource‐intensive. We present a pipeline to parameterize integral projection models (IPMs) using LiDAR data and hyperspectral‐based species maps to assess post‐fire recovery across large, forested areas at the Caribou ...

Do Single‐Sex STEM Programs Have Merit? If So, for Whom, on What Measures?

Science Education, EarlyView.
ABSTRACT Single‐sex STEM programs—defined here as voluntary, gender‐segregated extracurricular or supplemental activities (e.g., summer camps, workshops, robotics clubs, internships, or citizen science initiatives)—have experienced heightened popularity and scrutiny amid efforts to increase diversity in STEM fields.

The Multinomial Logistic Model for the Case in which the Response Variable Can Assume One of Three Levels and Related Models El modelo logístico multinomial para el caso en que la variable de respuesta puede asumir uno de tres niveles y modelos relacionados

Revista Colombiana de Estadística, 2012
The aim of this work is to examine multinomial logistic models when the response variable can assume three levels, generalizing a previous work of logistic models with binary response variables.

Reducing Trade‐Offs of Net Zero Carbon Transitions Through Entrepreneurship and Coordinated Innovation: A Spatially Disaggregated Analysis Across Countries and World Regions

Sustainable Development, EarlyView.
ABSTRACT Transition processes towards a sustainable future benefit from historic perspectives, since feasible changes of socio‐technological conditions and processes depend on a holistic assessment of how actors are embedded in existing institutions, routines, and structures. Building on the Income–Population–Affluence–Technology equation and utilizing

Farmers’ Preferences for Sustainable Crop Protection: An Integrated Choice and Latent Variable Approach

Sustainable Development, EarlyView.
ABSTRACT This study analyzes farmers' preferences for sustainable crop protection, focusing on Integrated Pest Management (IPM) practices by incorporating social‐psychological factors to capture economic and behavioral dimensions. Using data from German and Polish potato farmers, we apply an integrated choice and latent variable framework that combines

A High-dimensional Multinomial Logit Model

Journal of Applied Econometrics
The number of parameters in a standard multinomial logit model increases linearly with the number of choice alternatives and number of explanatory variables. Since many modern applications involve large choice sets with categorical explanatory variables, which enter the model as large sets of binary dummies, the number of parameters in a multinomial ...

Revisiting McFadden’s correction factor for sampling of alternatives in multinomial logit and mixed multinomial logit models

Transportation Research Part B: Methodological
In this paper, we revisit McFadden (1978)'s correction factor for sampling of alternatives in multinomial logit (MNL) and mixed multinomial logit (MMNL) models. McFadden (1978) proved that consistent parameter estimates are obtained when estimating MNL models using a sampled subset of alternatives, including the chosen alternative, in combination with ...
