Gazing at Haw Par villa: Cultural Tourism in Singapore

Tourism is an important and growing industry in Singapore. Studies on Singapore cultural tourism have generally focused on three major sites: Chinatown, Little India and the Malay Village. The Haw Par Villa tourist site has not been examined in recent years. The case study of Haw Par Villa offered here demonstrates how changing times in Singapore have affected the popularity of tourist sites in...

A characterization of trees with equal Roman 2-domination and Roman domination numbers

Given a graph $G=(V,E)$ and a vertex $v in V$, by $N(v)$ we represent the open neighbourhood of $v$. Let $f:Vrightarrow {0,1,2}$ be a function on $G$. The weight of $f$ is $omega(f)=sum_{vin V}f(v)$ and let $V_i={vin V colon f(v)=i}$, for $i=0,1,2$. The function $f$ is said to bebegin{itemize}item a Roman ${2}$-dominating function, if for every vertex $vin V_0$, $sum_{uin N(v)}f(u)geq 2$. The R...

A note on the Roman domatic number of a digraph

Roman dominating function} on a digraph $D$ with vertex set $V(D)$ is a labeling$fcolon V(D)to {0, 1, 2}$such that every vertex with label $0$ has an in-neighbor with label $2$. A set ${f_1,f_2,ldots,f_d}$ ofRoman dominating functions on $D$ with the property that $sum_{i=1}^d f_i(v)le 2$ for each $vin V(D)$,is called a {em Roman dominating family} (of functions) on $D$....

Diet at the Roman Village of Virovitica Kiskorija South, Croatia.

The Virovitica Kiskorija South site was a Roman village. In this paper archaeological, archaeobotanical, and archaeo-zoological finds are presented and interpreted, then compared with similar sites and information available from ancient sources. The site was divided into complexes that made a whole. The finds within each complex are presented and compared to similar archaeological sites, as wel...
