Annals of Public and Cooperative Economics, EarlyView.Abstract Many policymakers are unwilling, or think that it is infeasible, to perform comprehensive cost–benefit analysis (CBA) of programmes in social policy arenas. What principles actually underlie CBA? An understanding is necessary to assess whether other evaluation methods are close enough to CBA to provide useful information on social efficiency ...

Lexicographic Effect Algebras [PDF]
, 2014 In the paper we investigate a class of effect algebras which can be represented in the form of the lexicographic product $\Gamma(H\lex G,(u,0))$, where $(H,u)$ is an Abelian unital po-group and $G$ is an Abelian directed po-group.

The Simultaneous Metric Dimension of Families Composed by Lexicographic Product Graphs
, 2015 Let ${\mathcal G}$ be a graph family defined on a common (labeled) vertex set $V$. A set $S\subseteq V$ is said to be a simultaneous metric generator for ${\cal G}$ if for every $G\in {\cal G}$ and every pair of different vertices $u,v\in V$ there exists

Outer Independent Double Italian Domination of Some Graph Products
Theory and Applications of Graphs, 2023 An outer independent double Italian dominating function on a graph $G$ is a function $f:V(G)\rightarrow\{0,1,2,3\}$ for which each vertex $x\in V(G)$ with $\color{red}{f(x)\in \{0,1\}}$ then $\sum_{y\in N[x]}f(y)\geqslant 3$ and vertices assigned $0 ...

Area, EarlyView.Short Abstract This paper examines how the Royal Geographical Society's (RGS's) Library and Map Committee disciplined the exchange of the first English‐language geographical journal in the nineteenth century. The periodical's archive reveals the institutional mechanisms that shaped the journal's networks of gifting and exchange but also the deliberate ...

A Lexicographic Product Cancellation Property for Digraphs [PDF]
, 2012 There are four prominent product graphs in graph theory: Cartesian, strong, direct, and lexicographic. Of these four product graphs, the lexicographic product graph is the least studied.

New concepts on level graphs of vague graphs with application in medicine
Frontiers in Physics, 2023 Vague graphs (VGs), belonging to the fuzzy graph (FG) family, have good capabilities when facing problems that cannot be expressed by FGs. When an element membership is unclear, neutrality is a good option that can be well-supported by a VG. The previous

Disjoint Perfect Secure Domination in the Cartesian Product and Lexicographic Product of Graphs
International Journal For Multidisciplinary ResearchLet G be a graph. A dominating set D⊆V(G) is called a secure dominating set of G if for each vertex u∈V(G)∖D, there exists a vertex v∈D such that uv∈ E(G) and the set (D∖{v})∪{u} is a dominating set of G.

Exact Values of Zagreb Indices for Generalized T-Sum Networks with Lexicographic Product
Journal of mathematics, 2021 The use of numerical numbers to represent molecular networks plays a crucial role in the study of physicochemical and structural properties of the chemical compounds. For some integer k
