The Ramsey Theory of Henson graphs
, 2020 Analogues of Ramsey's Theorem for infinite structures such as the rationals or the Rado graph have been known for some time. In this context, one looks for optimal bounds, called degrees, for the number of colors in an isomorphic substructure rather than

Schreier sets in Ramsey theory [PDF]
Transactions of the American Mathematical Society, 2007 We show that Ramsey theory, a domain presently conceived to guarantee the existence of large homogeneous sets for partitions on k k -tuples of words (for every natural number k k ) over a finite alphabet, can be extended to one for partitions on Schreier-type sets of words (of every countable ordinal).

Negative learning emotions and learning goal orientation in teams: HRD implications
Human Resource Development Quarterly, Volume 36, Issue 1, Page 49-67, Spring 2025.Abstract Utilizing insights from team regulation theory and social cognitive theory, this research conducted empirical testing through a field survey involving engineering teams. This research is significant as it inspires teams to effectively harness their learning capacity, thereby enhancing collective motivation for future success.

Household Consumption Intentions by Income Group During Monetary Policy Easing and Tightening
International Journal of Finance &Economics, EarlyView.ABSTRACT We investigate how the monetary policy interest rate affects Brazilian households' consumption intentions under two distinct regimes: monetary easing and tightening cycles. Using data from low‐ and high‐income households, we assess both the magnitude and the dynamics of this relationship.

R ( 5 , 5 ) ≤ 46 $R(5,5)\le 46$
Journal of Graph Theory, EarlyView.ABSTRACT We prove that the Ramsey number R ( 5 , 5 ) $R(5,5)$ is less than or equal to 46. The proof uses a combination of linear programming and checking a large number of cases by computer. All of the computational parts of the proof were independently implemented by both authors, with consistent results.

Topological methods in zero-sum Ramsey theory
Forum of Mathematics, SigmaA landmark result of Erdős, Ginzburg, and Ziv (EGZ) states that any sequence of $2n-1$ elements in ${\mathbb {Z}}/n$ contains a zero-sum subsequence of length n.

Empowerment or Pressure? Exploring the Impact of Female Body Depictions in Body Positivity Instagram Posts on Self-Objectification. [PDF]
Int J PsycholABSTRACT Although Body Positivity content (BoPo) has been criticised for emphasising physical appearance and promoting self‐objectification, the specific features driving these effects remain unclear. The present study examined whether depictions of female bodies act as triggers for self‐objectification in BoPo on Instagram.

Treewidth Versus Clique Number. V. Further Connections With Tree‐Independence Number
Journal of Graph Theory, EarlyView.ABSTRACT We continue the study of ( tw , ω ) $({\mathsf{tw}},\omega )$‐bounded graph classes, that is, hereditary graph classes in which large treewidth is witnessed by the presence of a large clique, and the relation of this property to boundedness of the tree‐independence number, a graph parameter introduced independently by Yolov in 2018 and by ...

A linear upper bound in zero-sum Ramsey theory
International Journal of Mathematics and Mathematical Sciences, 1994 Let n, r and k be positive integers such that k|(nr). There exists a constant c(k,r) such that for fixed k and r and for every group A of order kR(Knr,A)≤n+c(k,r),where R(Knr,A) is the zero-sum Ramsey number introduced by Bialostocki and Dierker [1], and
