Measure‐valued processes for energy markets

open access: yesMathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Linking drought strategy to climate‐of‐origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

open access: yesNew Phytologist, EarlyView.
Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

The Impact of Digital Technologies on Skills‐to‐Job Mismatches

open access: yesNew Technology, Work and Employment, EarlyView.
ABSTRACT A pervasive discourse calls for worker upskilling amid ongoing digital transformation. This study introduces a skills‐to‐job mismatch perspective into research on the digital transformation of work by conceptualising technological adoption as a process that reshapes the relationship between workers’ skill endowments and evolving job ...

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

open access: yesPhotochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

On the Neighbourhood Polynomial

open access: yes, 2017
The neighbourhood polynomial of a graph is the generating function for the neighbourhood complex, which contains all subsets of vertices which have a common neighbour. We begin with some formulas for computing the neighbourhood polynomial. We then show a

Partisanship, Deservingness, and the Attitudinal Policy Feedback Process for Social Policy

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT In an era of identity‐based partisan polarization, we examine whether social policies can still generate positive attitudinal feedback among beneficiaries. Drawing on nationally representative survey data, we demonstrate that partisanship conditions the policy feedback process through divergent perceptions of group deservingness.

Decomposition-Based Method for Sparse Semidefinite Relaxations of Polynomial Optimization Problems [PDF]

open access: yes
We consider polynomial optimization problems pervaded by a sparsity pattern. It has been shown in [1, 2] that the optimal solution of a polynomial programming problem with structured sparsity can be computed by solving a series of semidefinite ...

‘Like a Fish in the Water’: Subjective Well‐Being and the Alignment of Perceptions of Democracy With Political Structures

open access: yesSociological Forum, EarlyView.
ABSTRACT Happiness research has long highlighted the role of national culture, yet few studies distinguish between objective conditions and collective cultural environments in which citizens form political perceptions. Focusing on perceptions of democracy, this study examines how discrepancies between personal perceptions and two dimensions of ...
