A graph G is pluperfect if one can add new multiple edges to obtain a multi graph M satisfying: (1) G spans M, (2) the degrees of the nodes of M are consecutive integers, (3) G and M have the same minimum degree. Our purpose is to display several families of pluperfect graphs in order to L Introduction My good friends Mehdi Behzad and Gary Chartrand wrote a note [1] titled "No graph is perfect"...

A removahedron is a polytope obtained by deleting inequalities from the facet description of the classical permutahedron. Relevant examples range from the associahedra to the permutahedron itself, which raises the natural question to characterize which nestohedra can be realized as removahedra. In this note, we show that the nested complex of any connected building set closed under intersection...

This paper presents a cognitive model which describes the effect of a CIO’s transformational leadership on empowerment and leadership performance. The empirical literature on transformational leadership and empowerment demonstrates strong effects on leadership performance, but the literature has been limited to inquiries dealing with one of these issues. However, there have been little articles...

The scope of this study is to identify what empowerment strategies were addressed for the promotion of health in health research, characterizing them from a socio-critical and post-structuralist standpoint. It involved an Integrative Review conducted in May 2011 of the Medline, Lilacs and SciELO databases. The inclusion criteria were complete research articles, case reports or experience report...

My purpose in writing this piece is to reflect upon a series of conversations in which I participated on the subject of empowerment over the past year. I believe that empowerment is key to innovation. For me, the essential aspect of the paper is my personal attempt to sort out why it is that employers, service providers and governments say they want to but do not reliably create empowerment in ...

A digraph D is round if the vertices of D can be circularly ordered as VI, V2, ... , Vn so that, for each vertex Vi, the out-neighbours of Vi appear consecutively following Vi and the in-neighbours of Vi appear consecutively preceding Vi in the ordering. We characterize round digraphs in terms of forbidden substructures. Our proof implies a polynomial algorithm to decide if a digraph is round.

Increased utilization of evaluation results has been the primary rationale for the development of participatory or stakeholder approaches. The assumption is that participation by various constituents in the evaluation process will increase their understanding of and commitment to the use of evaluation results. Another rationale for implementing a participatory evaluation approach is empowerment...
