How 1st‐Tier Suppliers Respond to Green Public Procurement Policies: An Empirical Analysis

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This article analyses how 1st‐tier suppliers to public organisations respond operationally to Green Public Procurement (GPP) policies. Through a multiple case study of 12 Italian firms operating in different sectors, we develop a classification of suppliers' responses, identifying two interrelated macro‐types: internal operations realignment ...

Perfect Roman and Perfect Italian Domination of Cartesian Product Graphs

Scientific Journal of King Faisal University: Basic and Applied Sciences
For a graph G=(V,E), a function f:V→{0,1,2} is a perfect Roman dominating function (PRDF) on G if every v∈V with f(v)=0 is adjacent to exactly one vertex u with f(u)=2. The sum ∑_(v∈V)^▒f (v) is the weight w(f) of f.

Ultrafast oscillations in the human brain and their functional significance

Epilepsia, EarlyView.
Abstract Objective The upper frequency limit of human brain activity remains unknown. Using ultrahigh sampling rate (≥20 kHz) intracranial microelectroencephalography, this study aimed to systematically explore and quantitatively characterize brain field oscillations beyond the established high‐frequency oscillation range (>2 kHz), and to determine ...

Roman domination in graphs [PDF]

, 2000
A Roman dominating function on a graph G =(V,E) is a function f: V →{0, 1, 2} satisfying the condition that every vertex u for which f(u) =0 is adjacent to at least one vertex v for which f(v)=2.Theweight of a Roman dominating function is the value f(V) =

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Geopolitics and global strategy: Making money under anarchy

Global Strategy Journal, EarlyView.
Abstract Research Summary Multinational firms conduct cross‐border trade and investment in a world of anarchy, where nation‐states must secure their survival in the absence of a world government. We develop a geopolitical‐economic order (GEO) framework to argue that the extent of geopolitical competition incentivizes states to create one of two types ...

Perfect Roman {3}-Domination in Graphs: Complexity and Bound of Perfect Roman {3}-Domination Number of Trees

Journal of Mathematics
A perfect Roman 3-dominating function on a graph G=V,E is a function f:V⟶0,1,2,3 having the property that if fv=0, then ∑u∈Nvfu=3, and if fv=1, then ∑u∈Nvfu=2 for any vertex v∈V.
