Signed Total Roman Domination in Digraphs [PDF]
, 2017 Let D be a finite and simple digraph with vertex set V (D). A signed total Roman dominating function (STRDF) on a digraph D is a function f : V (D) → {−1, 1, 2} satisfying the conditions that (i) ∑x∈N−(v)f(x) ≥ 1 for each v ∈ V (D), where N−(v) consists ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

[k]-Roman Domination in Digraphs
, 2023 Let D=(V(D),A(D)) be a finite, simple digraph and k a positive integer. A function f:V(D)→{0,1,2,…,k+1} is called a [k]-Roman dominating function (for short, [k]-RDF) if f(AN−[v])≥|AN−(v)|+k for any vertex v∈V(D), where AN&

Psychological Contracts With Purpose: A Review and Path Forward
Journal of Organizational Behavior, EarlyView.ABSTRACT This review advances the understanding of psychological contracts (PCs) that include third‐party beneficiaries and transcend self‐interested goals, which we term “PCs with purpose.” PC theory has challenged the assumption that social exchange relies solely on balanced rewards and inducements, highlighting that individuals may wish to ...

Bounds on the Hop Double Roman Domination Number of Graphs.
In this paper, we establish sharp upper and lower bounds for this parameter. These results provide the first systematic study of hop double Roman domination and lay the foundation for future investigations into its structural and computational aspects.

Some Progress on the Double Roman Domination in Graphs [PDF]
, 2019 For a graph G = (V,E), a double Roman dominating function (or just DRDF) is a function f : V → {0, 1, 2, 3} having the property that if f(v) = 0 for a vertex v, then v has at least two neighbors assigned 2 under f or one neighbor assigned 3 under f, and ...

Nonprofit Management and Leadership, EarlyView.ABSTRACT Under the roof of Christian churches in Central Europe, some nonprofit organizations (NPOs) grow, while others are in marked decline. Our study in this context extends a previous focus on financial indicators to NPO managers' experiences, their role clarity and job satisfaction, during phases of organizational growth and decline. Specifically,
