Landscape function analysis: a system for monitoring rangeland function
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: David Tongway Norman HindleyLandscape Function Analysis (LFA) is a monitoring procedure that uses quickly determined field indicators to assess the functional status of rangelands. As such, it complements existing procedures that assess condition. It comprises three modules — a conceptual framework, a field... -
Algebraic Entropy of Shift Endomorphisms on Abelian Groups
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Maryam Akhavin --- Faculty of Mathematical Sciences, Iran Dikran Dikranjan --- Dipartimento di Matematica e Informatica, Italy Anna Giordano Bruno --- Dipartimento di Matematica e Informatica, Italy Arezoo Hosseini --- Department of Mathematics, Faculty of Science, Iran Fatemah Ayatollah Zadeh Shirazi --- Faculty of Mathematics, Statistics and Computer Science, College of Science, IranFor every finite-to-one map λ : Γ → Γ and for every abelian group K, the generalized shift σλ of the direct sum ⊕Γ K is the endomorphism defined by (x i ) iεΓ ↦ (x λ(i)) iεΓ [3]... -
Roald Dahl: A psychosexual developmental trajectory study illustrated within psychobiography
Item type: Journal Article • Journal: Journal of Psychology in Africa • Authors: Paul Fouché --- Department of Psychology, Faculty of the Humanities, South Africa Tania Holz --- Department of Psychology, Faculty of the Humanities, South AfricaThis study applies analytical psychobiography, particularly Freud's psychoanalytic apporoach, to the study of the psychosexual development of Roald Dahl (1916–1990), a renowned children's author, gentleman spy, connoisseur, and philanthropist of his time.

Methods for assessing the impact of research on innovation and development in the agriculture and food sectors
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Ludovic Temple --- Cirad Umr Innovation, France Estelle Biénabe --- Cirad Umr Innovation, France Danielle Barret --- Cirad-Dgdrs, France Gilles Saint-Martin --- Cirad-Dgdrs, FranceThe need for technological transition and the context of the privatization of public research funding both challenge the evolution of methods to assess the impact of research in the agricultural and food sectors. We analyze this evolution through a literature... -
Structure, growth and growing space efficiency of Pinus radiata (D. Don) trees as affected by their social position
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Hans Pretzsch --- , Germany Andreas Rais --- , Germany Deon Malherbe --- , South Africa Antonio Ruano --- , Spain Hugo Lambrechts --- , The Netherlands Enno Uhl --- , Germany Ben du Toit --- , South AfricaCurrently, silvicultural prescriptions such as thinning monospecific stands from above and transitioning from monospecific to mixed-species stands are scrutinised regarding their ability to reduce stress and damage. That the quantity and quality of the trees harvested by intermediate and final...
