Star-wheel Ramsey numbers

open access: yes, 2005
Summary: For given graphs \(G\) and \(H\), the Ramsey number \(R(G,H)\) is the smallest natural number \(n\) such that for every graph \(F\) of order \(n\): either \(F\) contains \(G\) or the complement of \(F\) contains \(H\). This paper investigates the Ramsey number \(R(S_n,W_m)\) of stars versus wheels. We show that if \(m\) is odd, \(n\geq 3\) and

Beyond Sporting Talent: Other Determinants of Football Clubs’ Wage Bills

open access: yesBulletin of Economic Research, EarlyView.
ABSTRACT This article delves into the understanding of how football clubs determine wage bills to compensate talent. Using data from first‐division teams in elite European leagues, we estimate wage models based on indicators of sporting performance, “Elo ratings” as a proxy for clubs’ historical achievements and brand strength, and “media visibility ...

Luminescence dating of coastal deposits from the Chanthaburi Plain, Thailand

open access: yesBoreas, EarlyView.
The ongoing global sea‐level rise urges us to better understand the dynamics of coastal processes for predicting future changes. Sedimentary deposits reflect past coastal environments but require precise chronological data to place evidence into a temporal context.

On the Ramsey number of 4-cycle versus wheel

open access: yesIndonesian Journal of Combinatorics, 2016
For any fixed graphs $G$ and $H$, the Ramsey number $R(G,H)$ is the smallest positive integer $n$ such that for every graph $F$ on $n$ vertices must contain $G$ or the complement of $F$ contains $H$.

The commercialization of labour markets: Evidence from wage inequality in the Middle Ages

open access: yesThe Economic History Review, EarlyView.
Abstract This paper moves beyond the focus on ‘average’ wage trends in pre‐industrial economies by examining the broad diversity of pay rates and forms of remuneration across occupations and regions in medieval England. We find that whilst some workers enjoyed substantial growth in wage rates after the Black Death, there was a large group who ...

Size multipartite Ramsey numbers for small paths versus books

open access: yesIndonesian Journal of Combinatorics, 2016
Given $j \ge 2$,  for  graphs $G$ and $H$, the size Ramsey multipartite number $m_j(G, H)$ is defined as the smallest natural number $t$ such that any blue red coloring of the edges of the  graph $K_{j \times t}$, necessarily containes a red $G$ or a ...

Extreme weather and economic crisis in the 1430s in England, and the implications for tenurial change

open access: yesThe Economic History Review, EarlyView.
Abstract The 1430s were characterized by extreme weather conditions, food and fodder shortages, and high mortalities among animals and humans, although the severity of events and their consequences in England have received limited attention. The economic downturn and the depressed customary land market in this decade marked the beginning of the Great ...

Questions Should Have Answers

open access: yesEuropean Journal of Philosophy, EarlyView.
ABSTRACT Making sense of the world often requires one to come up with new ideas, including ideas one had previously been unable to think of. How and when should this be done? I propose and defend a norm of rationality linking wondering, belief, and abilities to conceive: one must not both wonder a question and reject all answers to it that one can ...

Limbal cystotomy by fine needle aspiration of a translucent iris cyst in a horse

open access: yesEquine Veterinary Education, EarlyView.
Summary A 4‐year‐old Cremello crossbred mare was referred to the Equine Veterinary Teaching Hospital of Utrecht University for a translucent iris cyst from the dorsal pupillary margin corpora nigra in the right eye. Although noninvasive diode laser treatment is the preferred method of pigmented cyst ablation, two attempts did not result in disruption ...
