Path-Star Ramsey numbers

Journal of Combinatorial Theory, Series B, 1974
AbstractLet f(m,n) be the least integer N such that for every graph G with N vertices, either G contains a path of m vertices or the complement of G contains a vertex of degree at least n. This paper determines f(m,n) for all m, n.

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.

A Note on Upper Bounds for Some Generalized Folkman Numbers

Discussiones Mathematicae Graph Theory, 2019
We present some new constructive upper bounds based on product graphs for generalized vertex Folkman numbers. They lead to new upper bounds for some special cases of generalized edge Folkman numbers, including the cases Fe(K3, K4 − e; K5) ≤ 27 and Fe(K4 −

Restricted size Ramsey number for P3 versus cycle

Electronic Journal of Graph Theory and Applications, 2020
Let F, G and H be simple graphs. We say F → (G,H) if for every 2-coloring of the edges of F there exists a red copy of G or a blue copy of H in F. The Ramsey number r(G,H) is defined as r(G,H) = min{|V(F)|: F → (G,H)}, while the restricted size Ramsey ...

A Guide to Key Decision Criteria for Likert‐Scale Use in Survey Research

Global Business and Organizational Excellence, EarlyView.
ABSTRACT Although widely used in survey research, the application of the Likert scale often lacks rigorous justification in relation to key methodological decisions. Furthermore, inconsistencies in terminology persist, for example, the common reference made to the “5‐point Likert scale,” even though debate is ongoing about the optimal number of ...

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

Journal of Quaternary Science, EarlyView.
Abstract Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

Journal of Quaternary Science, EarlyView.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

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

The Ramsey numbers of fans versus a complete graph of order five

Electronic Journal of Graph Theory and Applications, 2014
For two given graphs $F$ and $H$, the Ramsey number $R(F,H)$ is the smallest integer $N$ such that for any graph $G$ of order $N$, either $G$ contains $F$ or the complement of $G$ contains $H$.
