The most popular concept is the information society. In this book that concept is used in combination with the concept network society to typify contemporary developed and modern societies marked by a high level of information exchange and use o...

Double Derivations, Higher Double Derivations and Automatic Continuity

Let  be a Banach algebra. Let  be linear mappings on . First we demonstrate a theorem concerning the continuity of double derivations; especially that all of -double derivations are continuous on semi-simple Banach algebras, in certain case. Afterwards we define a new vocabulary called “-higher double derivation” and present a relation between this subject and derivations and finally give some ...

Vulnerability of Southern African Fauna and Flora to Climate Change

Temporal biodiversity change in transformed landscapes: a southern African perspective.

Landscape transformation by humans is virtually ubiquitous, with several suggestions being made that the world's biomes should now be classified according to the extent and nature of this transformation. Even those areas that are thought to have a relatively limited human footprint have experienced substantial biodiversity change. This is true of both marine and terrestrial systems of southern ...
