Veld is 'n lewensbelangrike natuurlike hulpbron vir ons aardse bestaan. Sowat 80% van ons mooi land bestaan uit veld. Die grootste deel daarvan word vir vee- en wildboerdery asook vir bewaring van biodiversiteit en vir ontspanning gebruik. Goeie veldbestuur is nodig om grondagteruitgang te stuit en om volhoubare voedselproduksie en bewaring van biodiversiteit te verseker. Maar goeie veldbestuur berus op 'n goeie kennis van ekologiese beginsels en veldbestuurspraktyke, iets wat baie grondgebruikers nie beskore was om te verkry nie. Die boek poog om die nodige kennis te verskaf om grondgebruikers te help om die grond in hul sorg doeltreffend te bestuur - inderdaad 'n reuseverantwoordelikheid. Die insluiting van meer as 380 foto's en illustrasies en die gebruik van maklik verstaanbare taal in Veldbestuur - Beginsels en Praktyke is daarop gemik om die taamlik tegniese onderwerp te vereenvoudig.

Philosophical and ethical discussions of warfare are often tied to emerging technologies and techniques. Today we are presented with what many believe is a radical shift in the nature of war-the realization of conflict in the cyber-realm, the so-called "fifth domain " of warfare. Does an aggressive act in the cyber-realm constitute an act of war? If so, what rules should govern such warfare? Are the standard theories of just war capable of analyzing and assessing this mode of conflict? These changing circumstances present us with a series of questions demanding serious attention. Is there such a thing as cyberwarfare? How do the existing rules of engagement and theories from the just war tradition apply to cyberwarfare? How should we assess a cyber-attack conducted by a state agency against private enterprise and vice versa? Furthermore, how should actors behave in the cyber-realm? Are there ethical norms that can be applied to the cyber-realm? Are the classic just war constraints of non-combatant immunity and proportionality possible in this realm? Especially given the idea that events that are constrained within the cyber-realm do not directly physically harm anyone, what do traditional ethics of war conventions say about this new space? These questions strike at the very center of contemporary intellectual discussion over the ethics of war. In twelve original essays, plus a foreword from John Arquilla and an introduction, Binary Bullets: The Ethics of Cyberwarfare, engages these questions head on with contributions from the top scholars working in this field today.

Die grasfamilie, bekend as Poaceae, is waarskynlik die belangrikste plantfamilie op aarde. Grasse is die eerste voedselplante wat deur mense aangeplant is. Graangewasse, soos mielies, koring, rys en suikerriet (almal grasse), is steeds ons belangrikste bron van energie. Gras, in die vorm van voer, is ook die belangrikste bron van kos vir vee en die groot kuddes grasvreters in die natuur. Die akkurate identifikasie van grasse raak belangrik tydens veldbestuur aangesien grasse ten opsigte van hul weidingswaarde en ander ekologiese funksies verskil. Verder reageer verskillende onkruidgrasse anders op chemise onkruiddoders en moet daarom akkuraat geidentifiseer word. Hierdie boek, Gids tot Grasse van suider-Afrika, is die omvattendste volkleur identifikasiegids tot die algemene grasse in suider-Afrika en sluit onder meer die volgende kenmerke in: Beskrywings en illustrasies van die 320 belangrikste grasse in suider-Afrika; 'n Gebruikersvriendelike indentifikasiesleutel; Meer as 1 000 uitstekende kleurfoto's; Dertien kort en volledig geillustreerde inleidende hoofstukke oor grasse; Algemene grasname in verskeie inheemse tale; Simbole wat die leser in staat stel om inligting met 'n oogopslag te bekom.
