Wilf Equivalences for Patterns in Rooted Labeled Forests [PDF]

, 2023
Building off recent work of Garg and Peng, we continue the investigation into classical and consecutive pattern avoidance in rooted forests, resolving some of their conjectures and questions and proving generalizations whenever possible.

Wilf-Equivalence on $k$-ary Words, Compositions, and Parking Functions [PDF]

The Electronic Journal of Combinatorics, 2009
In this paper, we study pattern-avoidance in the set of words over the alphabet $[k]$. We say that a word $w\in[k]^n$ contains a pattern $\tau\in[\ell]^m$, if $w$ contains a subsequence order-isomorphic to $\tau$. This notion generalizes pattern-avoidance in permutations.

Using large language models to analyze political texts through natural language understanding

American Journal of Political Science, Volume 70, Issue 4, Page 1589-1605, October 2026.
Abstract Large language models (LLMs) offer scalable alternatives to human experts when analyzing political texts for meaning, using natural language understanding (NLU). Qualitative NLU methods relying on human experts are severely limited by cost and scalability.

Civic ecosystem responses to compound crises: evidence from Syria

Disasters, Volume 50, Issue 4, October 2026.
Abstract Compound crises have attracted growing interest from scholars and policymakers in recent years. Little attention, however, has been directed to the social relations that emerge from and respond to such phenomena. This paper closes the gap by investigating the emergence, impact, and limitations of the civic ecosystem that responded to the ...

The Goldilocks Effect: How the “Just Right” Writing Styles of Global Corporate Responsibility Frameworks Shapes Their Use by Businesses

Regulation &Governance, Volume 20, Issue 4, Page 1955-1981, October 2026.
ABSTRACT The 21st century has witnessed a surge in the number of global corporate responsibility (GCR) frameworks issued by international organizations (IOs). Our study investigates whether and to what extent these frameworks shape businesses' Corporate Social Responsibility (CSR) communications.

Austrocedrus from the Late Cretaceous of Antarctica and its implications for the early evolution of southern cypresses (Callitroideae, Cupressaceae)

American Journal of Botany, Volume 113, Issue 9, September 2026.
Abstract Premise The modern distribution of the southern cypresses, Callitroideae (Cupressaceae), reflects a classic Gondwanan distribution. The initial diversification of Callitroideae is estimated to have occurred during the Cretaceous, yet fossils from this period are rare, hampering our understanding of its early evolutionary history.

Introduction: Towards a linguistic anthropology of AI Introduction : vers une anthropologie linguistique de l'IA

Journal of the Royal Anthropological Institute, Volume 32, Issue 3, Page 967-982, September 2026.
This essay introduces the themed cluster of articles, ‘Towards a linguistic anthropology of AI’. The advent of artificial intelligence (AI), especially in large language models capable of producing coherent discourse mimicking conversational interaction, is exerting unprecedented pressure on prevailing concepts of language, personhood, and the human ...

From talking tools to metahumans: social interaction, semiotic skill, and the authority of AI chatbots Des outils parlants aux métahumains : interactions sociales, compétences sémiotiques et autorité des robots conversationnels

Journal of the Royal Anthropological Institute, Volume 32, Issue 3, Page 1022-1039, September 2026.
What does it take to turn a tool into a talking tool and that into an ultimate authority? Generative artificial intelligence (GenAI) in its diverse forms, such as large language models (LLMs), is celebrated as a useful tool. But LLM‐based conversational agents, or chatbots, the software applications through which ordinary users are likely to engage ...

Descents and des-Wilf equivalence of permutations avoiding certain nonclassical patterns [PDF]

Involve, a Journal of Mathematics, 2019
A frequent topic in the study of pattern avoidance is identifying when two sets of patterns $Π, Π'$ are Wilf equivalent, that is, when $|\text{Av}_n(Π)| = |\text{Av}_n(Π')|$ for all $n$. In recent work of Dokos et al. the notion of Wilf equivalence was refined to reflect when avoidance of classical patterns preserves certain statistics. In this article,
