Risk return of forward contracting corn with crop insurance
Journal of the Agricultural and Applied Economics Association, Volume 5, Issue 2, Page 139-153, June 2026.Abstract Forward contracting is a common pre‐harvest marketing strategy for row crops, with evidence suggesting higher prices during summer months due to embedded weather risk premiums. While aggressive forward contracting increases farmers' yield risk and potential non‐delivery penalties, crop revenue protection can help offset these financial burdens.

Journal of Sociolinguistics, Volume 30, Issue 3, Page 255-267, June 2026.ABSTRACT Sociolinguistic research has long documented the appropriation of African American Vernacular English (AAVE) across media including film, music and advertising. In this article, we add to this body of work by exploring the digital recontextualisation of a subset of AAVE features as ‘TikTok/internet language’.

RESEARCH ON DYNAMIC SYSTEM RELIABILITY MODEL OF HIGH DIMENSIONAL COPULA FUNCTION
Jixie qiangdu, 2022 Aiming at the dynamic mechanical system with multiple failure correlation, the copula function is used to describe the correlation of failure modes among units, and a reliability model of dynamic mechanical system with multiple failure correlations is ...

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Large‐scale vegetation restoration is reshaping belowground systems globally, yet root dynamics remain poorly quantified, limiting predictions of ecosystem resilience to hydroclimatic variability. Rooting depth reflects a trade‐off between carbon benefits and respiratory costs, but assessment is hampered by soil‐moisture uncertainty and weak ...

Seismic Reliability Analysis of Reinforced Concrete Arch Bridges Considering Component Correlation
BuildingsTo more effectively account for the correlation between components in the seismic reliability analysis of reinforced concrete arch bridges, this study proposes a system seismic reliability analysis method based on the D-vine Copula function. First, based

Application of a Vine Copula for Multi-Line Insurance Reserving
Risks, 2020 This article introduces a novel use of the vine copula which captures dependence among multi-line claim triangles, especially when an insurance portfolio consists of more than two lines of business. First, we suggest a way to choose an optimal joint loss

Molecular Reproduction and Development, Volume 93, Issue 4, April 2026.Post‐metamorphic gonadal development in Xenopus tropicalis was analyzed through integrated morphometric, histological, and transcriptional approaches. Males showed upregulation of cyp17, amh, and amhr2, whereas females exhibited an increased aldh1a2 and ddx4.
