TL;DR: An experiment was conducted wherein a repeated presentation of a stimulus was followed by a new stimulus and it was predicted that attention, as measured by orientation of the head and fixation of the eyes, cardiac deceleration, smiling, and pointing, would show response decrement over repeated trials of S1 and will show response recovery to S2.

TL;DR: Becium homblei, a flowering plant of the family Labiatae indigenous to Zambia, has been found to grow on soils contaminated with high levels of copper, suggesting that the metal may be bound as a complex with protein in the plant tissue.
Abstract: Summary Becium homblei, a flowering plant of the family Labiatae indigenous to Zambia, has been found to grow on soils contaminated with high levels of copper. The plant is capable of accumulating more than 100 ppm of the metal in its leaves and roots. Serial extraction of the plant tissue with various solvents has shown that much of the accumulated metal is tightly bound within the plant and is not in free solution in ionic form. The finding that increased copper content is accompanied by an increase in total nitrogen suggests that the metal may be bound as a complex with protein in the plant tissue.

TL;DR: Children in Siavonga, a tourist centre on the Zambian side of Lake Kariba, have been found to be infected with both urinary and intestinal schistosomiasis, indicating that there is active transmission of the diseases in the area.
Abstract: Children in Siavonga, a tourist centre on the Zambian side of Lake Kariba, have been found to be infected with both urinary and intestinal schistosomiasis, indicating that there is active transmission of the diseases in the area. The snails involved seem to be Bulinus africanus and Biomphalaria pfeifferi, and it is suggested that mats of the water weed Salvinia auriculata could provide microhabitats for colonies of the snail and thereby provide foci for the transmission of the diseases.

TL;DR: In this article, the methode non-verbale classique was used to evaluate enfants de culture non-europeenne in a group of enfantines controle d'origine et d'education.
Abstract: Pour la premiere fois, selon l'A., l'etude de la conservation a ete realisee avec une methode non-verbale sur des enfants de culture non-europeenne. Les resultats qui ont ete obtenus avec cette methode dans un groupe controle d'enfants d'origine et d'education europeennes sont comparables a ceux qui ont ete trouves en Suisse et aux Etats-Unis avec la methode genevoise classique. On peut done s'appuyer avec une certaine confiance sur ce fait pour analyser les resultats obtenus par la methode non-verbale avec 200 eleves d'ecole primaire de Zambie et les comparer aux donnees d'une etude australienne sur des enfants aborigenes dans laquelle la methode classique a ete utilisee. La moitie environ des enfants zambiens atteignent l'adolescence sans reussir les epreuves de conservation du poids; l'A. degage les implications et les causes possibles d'un tel fait, et specialement l'influence des facteurs de milieu: par exemple, la langue qui est utilisee comme vehicule d'education, egalement la qualite du m...

TL;DR: In this paper, a test d'appariement par la couleur ou la forme was proposed, and the results showed that the preference for the forme had a high correlation with the niveau d'instruction.
Abstract: Huit groupes de sujets, differant par l'instruction et la culture, ont ete soumis a un test d'appariement par la couleur ou la forme. (1) Plus le niveau d'instruction s'eleve et plus se manifeste une preference pour la forme, chez les enfants anglais citadins, les Indiens citadins et les Zambiens ruraux, mais non chez les enfants zambiens habitant la brousse lointaine ou la ville. (2) La preference pour la forme a un rapport moins direct avec l'[acaron]ge qu'avec l'instruction chez les enfants zambiens ruraux. (3) Les enfants Zambiens ruraux et citadins preferent plus frequemment la couleur que les enfants anglais et indiens citadins et moins frequemment que les enfants zambiens de brousse lointaine de měme niveau scolaire. (4) Les etudiants zambiens preferent plus frequemrnent la forme que les Zambiennes adultes illettrees. (5) Aucune difference entre races n'appara[icaron]t chez les sujets d'un jardin d'enfants privilegie.

TL;DR: In this article, a paraphrases de relativite linguistique, l'influence of l'education and celle de la culture pourraient s'expliquer par la "codabilite" des couleurs and des formes.
Abstract: L'A. traite des differences selon les cultures dans l'attention preferentielle accordee a la forme ou a la couleur, dans le contexte des caracteristiques propres aux echantillons qui sont en correlation avec cette preference. Il fait la revue des recherches anterieures qui ont decrit l'influence de l'[acaron]ge chronologique, considere comme refletant l'impact de l'education, de la surdite, du sexe et de la personnalite. Selon une hypothese de relativite linguistique, l'influence de l'education et celle de la culture pourraient s'expliquer par la “codabilite” des couleurs et des formes: l'A. presente une recherche experimentale qui montre qu'une telle hypothese ne rend pas compte des differences interculturelles et propose une autre explication, a savoir l'influence de l'experience perceptive qui entra[icaron]nerait la familiarisation avec les formes abstraites.

TL;DR: The effect of these distributional findings on existing hypotheses of insect‐vectored virus aetiology of the tumours is discussed and the need for further and more accurate studies in south‐central Africa is stressed.
Abstract: Two hundred and three cases of the African lymphoma based on doctors' recall of cases are mapped and examined with reference to their geographical distribution. Altitude is shown to be important but minimum temperature is questioned. The effect of these distributional findings on existing hypotheses of insect-vectored virus aetiology of the tumours is discussed and the need for further and more accurate studies in south-central Africa is stressed. Such work should become possible shortly with the establishment of uniform Cancer Registries in the territories. Le Lymphone Africain en Afrique Centrale L'article examine la distribution geographique de 293 cas de lymphome africain, d'apres les indications des medecins qui ont vu ces cas. II montre que l'altitude joue un rǒle important mais que celui de la temperature minimale est douteux. Il analyse la distribution de ces cas par rapport aux hypotheses en cours sur l'intervention d'un virus transmis par un insecte vecteur et souligne qu'il serait necessaire de faire des etudes plus approfondies et plus precises dans le centre-sud de l'Afrique. La creation de fichiers uniformes du cancer dans les territoires interesses devrait permettre d'entreprendre ces travaux.

TL;DR: In this article, Hough et al. attempted to attempt a definition or a classification of the values of social work and found that a considerable amount of thinking and writing has been done in relation to this most obscure part of our humanistic concern.
Abstract: *Mr. Hough is Professor of Social Work and Head of the Oppenheimer Department of Social Service, University of Zambia, Lusaka, Zambia. T is not the main purpose of this paper t to attempt a definition or a classification of the values of social work. A considerable amount of thinking and writing has been done in relation to this most obscure part of our humanistic concern and this has been done mainly by philosophers and social scientists, but it will take many years yet before

TL;DR: In this paper, the authors present an account of the establishment of the psychology department at the University of Zambia, a relatively recently independent African country, where the full subject, not just one aspect of it, is recognized in its own right in the university concerned.
Abstract: Inevitably, the interpretation of the title must be a limiting one. First, by “African university” I mean a university in a relatively recently independent African country; second, by “department of psychology” I mean to imply that the full subject, not just one aspect of it, is recognized in its own right in the university concerned; and third, I can only write with confidence about what I known to be accurate. As a consequence, this paper will be almost wholly an account of the establishment of psychology in the University of Zambia. It is my hope that others will in due course contribute similar accounts of comparable growth elsewhere in independent Africa: I have in mind particularly the universities of francophone Africa, where there is a long tradition of significant psychological research, and also the very welcome though curiously belated developments at the Universities of Ghana and Lagos, and at Makerere University College of the University of East Africa.
