Typically, national strategies call for the establishment of a cyber operations unit capable of computer network defence, exploitation, and, in some nations, attack. The cyber operations unit will be manned by professionals and operate under governmen...

Let G = (V,E) be a graph. For a non-empty subset of vertices S ⊆ V , and vertex v ∈ V , let δS(v) = |{u ∈ S : uv ∈ E}| denote the cardinality of the set of neighbors of v in S, and let S = V − S. Consider the following condition: δS(v) ≥ δS(v) + k, (1) which states that a vertex v has at least k more neighbors in S than it has in S. A set S ⊆ V that satisfies Condition (1) for every vertex v ∈ ...

Causing people to take offense can occur when a marketer undertakes a controversial advertising campaign. What can make this a particularly important issue is when companies make what for many individuals is a controversial product, like condoms, erectile dysfunction drugs, feminine hygiene products and certain kinds of underwear.
