Specification Tests for Jump‐Diffusion Models Based on the Characteristic Function

open access: yesInternational Statistical Review, EarlyView.
Summary Goodness‐of‐fit tests are suggested for several popular jump‐diffusion processes. The suggested test statistics utilise the marginal characteristic function of the model and its L2‐type discrepancy from an empirical counterpart. Model parameters are estimated either by minimising the aforementioned L2‐type discrepancy or by maximum likelihood ...

Collective Bargaining and Monopsony: The Regulation of Noncompete Agreements in France

open access: yesIndustrial Relations: A Journal of Economy and Society, EarlyView.
ABSTRACT Can collective bargaining mitigate monopsony power? This paper studies the extent to which collective agreements regulating employee noncompete clauses affect firm‐level markdowns in French manufacturing. Using a staggered difference‐in‐differences design, we find that such regulation reduces markdowns by 1.3%–2.2% on average.

Chronic Health Condition Trajectories and Multimorbidity in Older Adults With Intellectual Disability: A Brief Report of 15 years of Longitudinal Evidence From IDS‐TILDA

open access: yesJournal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Adults with intellectual disability experience significant health issues that increase with age. Longitudinal analyses offer important evidence on how the trajectories of these conditions' develop and change. Methods Data were drawn from five waves of IDS‐TILDA, with a nationally representative sample of over 700 adults with ...

The Origins of Ploem's Filter Cube: A Pandora's Box

open access: yesJournal of Microscopy, EarlyView.
Abstract Ploem's filter cube, central to modern epifluorescence microscopy, integrates three matched optical components: an excitation filter, an emission filter, and a dichroic mirror. Together, these elements enable the separation of excitation and emission light paths, producing high‐contrast fluorescence images.

Histological analysis of incremental markings and crown growth characteristics in mandibular first molars of the red fox, Vulpes vulpes (Canidae, Mammalia)

open access: yesJournal of Anatomy, EarlyView.
This paper histologically analyzed incremental markings in dental enamel of red fox and grey wolf. Our results demonstrate that previous studies have misidentified these markings, which led to miscalculation of dental growth parameters. Abstract The present study analyzed incremental markings in the enamel of eight mandibular first molars (M1) of red ...
