Protection Motivation Theory and Farmers' Participation in Futures Markets: Evidence From Germany

Agribusiness, EarlyView.
ABSTRACT This study examines why German farmers show limited adoption of commodity futures contracts despite substantial price volatility, applying Protection Motivation Theory (PMT) to understand the cognitive processes driving participation decisions in futures markets. Survey data from 303 German farmers collected in 2024 were analyzed using Partial

Interpretability and Representability of Commutative Algebra, Algebraic Topology, and Topological Spectral Theory for Real‐World Data

Advanced Intelligent Discovery, EarlyView.
This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

PARTIAL LEAST SQUARES REGRESSION $PLS$ ON INTERVAL DATA

Revista de la Facultad de Ciencias, 2016
Uncertainty in the data can be considered as a numerical interval in which a variable can assume its possible values, this has been known as interval data. In this paper the $PLS$ regression methodology is extended to the case where explanatory, response variables and coefficients regression are intervals.

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

American Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

On robust partial least square (pls) methods

, 2009
PLS regression methods have been used in applied fields for two decades. Techniques based on iteratively reweighted regression have appeared in the specialized Iiterature with the contaminated data case. We propose a new robust PLS technique based on the Stahel-Donoho estimator.

Extent of Sinus Surgery Is Associated With Disease Control in Biologic Treated Type 2 Dominant CRS

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background A greater benefit of biologics is observed after surgery in Type 2 chronic rhinosinusitis with nasal polyps (CRSwNP). However, the extent of surgery remains undefined in many studies. This study evaluated the extent of surgery on disease control in patients receiving biologics for refractory Type 2 dominant CRSwNP.

Microbial‐Metabolite Signatures Are Associated With Glucocorticoid Responsiveness in Chronic Rhinosinusitis With Nasal Polyps

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) exhibit heterogeneous responses to oral glucocorticoids (GCs), but the biological basis of this variability remains unclear. Objective To identify gut microbiome‒plasma metabolomic signatures associated with GC responsiveness in CRSwNP patients and to compare their ...

Application of GA-PLS and GA-KPLS calculations for the prediction of the retention indices of essential oils

Química Nova, 2011
Genetic algorithm and partial least square (GA-PLS) and kernel PLS (GA-KPLS) techniques were used to investigate the correlation between retention indices (RI) and descriptors for 117 diverse compounds in essential oils from 5 Pimpinella species gathered

The PLS (partial least squares) approach to multidimensional contingency tables

, 1982
The present paper shows that the basic design for PLS estimation of soft models allows straightforward adaptation to the analysis of the dichotomous items of multidimensional contingency tables. The ensuing model defines one or more latent variables for each margin of the contingency table; the observed items are interpreted as indicators of the ...
