Time‐Varying Dispersion Integer‐Valued GARCH Models
Journal of Time Series Analysis, EarlyView.ABSTRACT We introduce a general class of INteger‐valued Generalized AutoRegressive Conditionally Heteroscedastic (INGARCH) processes by allowing simultaneously time‐varying mean and dispersion parameters. We call such models time‐varying dispersion INGARCH (tv‐DINGARCH) models.

“The Excuses We Make”: Defining Eight Corruption Rationalization Categories
Regulation &Governance, EarlyView.ABSTRACT The rationalization of corruption allows individuals to detach from moral imperatives, enabling them to perceive unethical or unlawful actions as acceptable or justifiable. Closely linked to the concept of moral disengagement, rationalization involves cognitive distortions that frame inhumane or immoral behavior as neither wrong nor ...

Infra‐culture and infrastructures: Relational placemaking at the coast
Transactions of the Institute of British Geographers, EarlyView.Short Abstract This article explores the concept of infra‐culture, emphasising how cultural practices and material interactions influence the development of physical infrastructures over time. Using the Alde and Ore estuary in eastern England as a case study now increasingly disrupted by climate change, it examines the role of infra‐culture in shaping ...

Character sum, reciprocity, and Voronoi formula
Bulletin of the London Mathematical Society, EarlyView.Abstract We prove a novel four‐variable character sum identity that serves as a twisted, non‐Archimedean analog of Weber's integrals for Bessel functions. Using this identity and ideas from Venkatesh's thesis, we provide a short spectral proof of the Voronoi formulae for classical modular forms with character twists.

Women in space: A review of known physiological adaptations and health perspectives
Experimental Physiology, EarlyView.Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.
