Use of Indigenous Stone Play in Child Psychological Assessment
Item type: Journal Article • Journal: Journal of Psychology in Africa • Authors: Nerine Daphné Odendaal --- University of the Western Cape, South Africa Mokgadi Moletsane --- University of the Western Cape, South AfricaThe purpose of the study was to investigate an indigenous stone play called Masekitlana, as a projection technique in child psychological assessment. A qualitative research approach, guided by an interpretivist epistemology, was applied. An intrinsic case study design was employed... -
Multivalued linear projections
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: R.W. Cross D.L. WilcoxA multivalued linear projection operator P defined on linear space X is a multivalued linear operator which is idempotent and has invariant domain. We show that a multivalued projection can be characterised in terms of a pair of subspaces and... -
TOPOLOGICAL DECOMPOSITIONS OF THE DUALS OF LOCALLY CONVEX VECTOR SEQUENCE SPACES
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: JanH Fourie --- Depart. of Mathematics Potchefstroom, South Africa WilliamH Ruckle --- Depart. of Mathematical Sciences, United States of AmericaLet Λ be a scalar sequence space which is endowed with a normal locally convex topology. For a separated locally convex space E we denote by Λ(E) the vector space of all sequences g in E for which (>g(i),a<) ε... -
The future of AIDS in Africa: lessons from two scenario projects
Item type: Journal Article • Journal: African Journal of AIDS Research • Authors: Pieter FourieScenario planning or futures studies have their origin in military planning, but have also been used with great success in the private sector, most notably in the energy industry. UNAIDS and the South African financial services group Metropolitan each recently... -
Into isomorphisms in tensor products of Banach spaces
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Eve Oja Vaiki RandalaWe establish quantitative extensions of two Grothendieck's results on into isomorphisms in projective tensor products. Among others, we prove the following. Let Y be a closed subspace of a Banach space Z and let j : Y → Z denote... -
Testing the suitability of the Nepal-Somers stand table projection method for Eucalyptus grandis plantations in South Africa
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: J Corral-Rivas --- Facultad de Ciencias Forestales, México S Sánchez Orois --- , Germany H Kotze --- , South Africa K von Gadow --- , GermanyThis study presents an application of a stand table projection method for varying stand densities of Eucalyptus grandis in South Africa. The projections of diameter at breast height (dbh) class frequencies are compatible with future values of basal area and... -
Eigenprojections and functions of a square matrix
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Christoph Hamburger --- University of Bonn, GermanyWe present polynomials for the eigenprojections or Frobenius covariants of a matrix A ∈ C n ×n . They allow for a computation of a function of A by a generalization of the Sylvester formula. -
Estimating the cost and efficiency gain of rolling out a multi-month dispensing programme for antiretroviral treatment in Tanzania
Item type: Journal Article • Journal: African Journal of AIDS Research • Authors: George Ruhago --- Muhimbili University of Health and Allied Sciences, Tanzania Steven Forsythe --- , USA Roland Van de Ven --- , USA Louis Apicella --- , USABackground: Globally, efforts to curtail the HIV pandemic are growing. The Joint United Nations Programme on HIV and AIDS (UNAIDS) and partners set the 95-95-95 targets to be achieved by 2025. Tanzania’s ongoing transition from single-month ARV to longer multi-month... -
Cross-section measures, radii, and Radon curves
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Horst Martini --- University of Technology Chemnitz, Germany Zokhrab Mustafaev --- University of Houston-Clear Lake, USAThe purpose of this paper is to study cross-section measures and their connections to Radon curves in two-dimensional Minkowski spaces. More precisely, we use results on cross-section measures to present, for nomed planes, inner and outer radii of the unit... -
Conditional indicators
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Dorsaf Cherif --- , Tunisia Emmanuel Lepinette --- Paris Dauphine University, FranceIn this paper, we introduce a large class of (so-called) conditional indicators, on a complete probability space with respect to a sub σ-algebra. A conditional indicator is a positive mapping, which is not necessary linear, but may share common features... -
HIV incidence and prevalence projections for Zimbabwe: Findings from five mathematical models
Item type: Journal Article • Journal: African Journal of AIDS Research • Authors: Isaac Taramusi --- UNAIDS UCO Zimbabwe, Zimbabwe John Stover --- , United States of America Robert Glaubius --- , United States of America Tsitsi Apollo --- Ministry of Health and Child Care, Zimbabwe Getrude Ncube --- Ministry of Health and Child Care, Zimbabwe Owen Mugurungi --- Ministry of Health and Child Care, Zimbabwe Ngwarai Sithole --- Ministry of Health and Child Care, Zimbabwe Loveleen Bansi-Matharu --- Institute for Global Health, University College London, United Kingdom Jenny Smith --- Institute for Global Health, University College London, United Kingdom Andrew Phillips --- Institute for Global Health, University College London, United Kingdom Valentina Cambiano --- Institute for Global Health, University College London, United Kingdom Daniel T Citron --- New York University Grossman School of Medicine, United States of America Anna Bershteyn --- New York University Grossman School of Medicine, United States of America Debra ten Brink --- Burnet Institute, Australia Rowan Martin-Hughes --- Burnet Institute, Australia Michael Pickles --- Medical Research Council Centre for Global Infectious Disease Analysis, Imperial College London, United Kingdom Paul Revill --- University of York, United Kingdom Amon Mpofu --- National AIDS Council of Zimbabwe, Zimbabwe Jeffrey Imai-Eaton --- Chan School of Public Health, Center for Communicable Diseases Dynamics, Harvard University, United States of America Richard Makurumidze --- Faculty of Medicine and Health Sciences, University of Zimbabwe, Zimbabwe Simbarashe Rusakaniko --- Faculty of Medicine and Health Sciences, University of Zimbabwe, ZimbabweIntroduction: Understanding how HIV epidemics are likely to behave in the future is key to informing HIV response strategies in low-income countries. Up-to-date HIV epidemiological estimates are important for policy decision- making, but surveillance data can be out of date... -
Characterizations of the semi-harmonious and harmonious quasi-projection pairs on Hilbert C ∗-modules
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Xiaoyi Tian --- Shanghai Normal University, P.R. China Qingxiang Xu --- Shanghai Normal University, P.R. China Chunhong Fu --- Health School Attached to Shanghai University of Medicine & Health Sciences, P.R. ChinaFor each adjointable idempotent Q on a Hilbert C ∗ -module , a specific projection m(Q) called the matched projection of Q was introduced recently due to the characterization of the minimum value among all the distances from projections to Q...
