Training to use Television as a Teacher

Television, no longer in its infancy, no longer a novelty, still possesses the unique ability to focus, one may even say command, the attention of both the individual and the group. It is no doubt due to this quality that the use of television has developed greatly during recent years. The fact that it can keep pace with the contemporary scene (e.g. important events can be shown ‘live’ or soon after they have taken place) plus the personal method of presentation may have made it something more than a ‘teaching aid’.     

Cultural interpretations of the visual meaning of icons and images used in North American web design

This study examines cross‐cultural interpretations of icons and images drawn from US academic websites. Participants from Morocco, Sri Lanka, Turkey, and the USA responded to an online questionnaire containing 18 icons and images representing online functions and information types common on US academic websites. Participants supplied meanings for icons and images and selected a preferred image to represent each of four specific online functions. From three images of professors, participants chose one with whom they would prefer to study. Data were collected at the University of New Mexico, USA; in Internet cafes in the Middle Atlas region and at Al‐Akhawayn University, Morocco; the Open University of Sri Lanka in Nawala, Nugegoda; and at Anadolu University, Turkey. A qualitative analysis examines participants' perspectives and preferences for specific representations and identifies cultural themes in relation to Hofstede's dimensions. Implications for the design of images for cross‐cultural users are discussed.

L'interprétation culturelle de la signification visuelle des icônes et images utilisées dans la conception de sites Web en Amérique du Nord

La présente étude porte sur les interprétations transculturelles des icônes et des images extraites de sites universitaires américains. Des participants venus du Maroc,du Sri Lanka, de Turquie et des Etats Unis, ont répondu à un questionnaire en ligne contenant 18 icônes et images représentant des fonctions en ligne et des modes d'information que l'on trouve couramment sur les sites universitaires américains. Ces participants ont attribué des significations aux icônes et images et sélectionné l'image qu'ils (elles) préféraient pour représenter chacune des quatre fonctions en ligne proposées. A partir de trois images de professeurs,les participants en ont choisi une, celle avec qui ils (elles) préféreraient étudier. Une étude quantitative examine les perspectives des participants et leurs préférences pour une représentation donnée et elle identifie les thèmes culturels par rapport aux dimensions de Hofstede. On étudie les conséquences que cela peut avoir pour la conception d'images destinées à des utilisateurs interculturels.

Kulturelle Interpretationen der visuellen Bedeutung der Symbole und Bilder, die in Nordamerika Web‐Design benutzt werden

Diese Studie untersucht cross‐kulturelle Interpretationen von Symbolen und Bildern, die in akademischen US‐Websites benutzt werden. Teilnehmer aus Marokko, Sri Lanka, der Türkei und den USA bearbeiteten einen Online‐Fragebogen mit 18 Ikonen und Bildern, die Online‐Funktionen und – Informationen auf akademischen US‐Websites gemeinsamen sind. Die Teilnehmer benannten angenommene Bedeutungen der Symbole und Bilder und wählten ein bevorzugtes Bild für jede der vier spezifischen Online‐Funktionen aus. Aus drei Bildern von Professoren wählten die Teilnehmer eines aus, das denjenigen zeigen sollte, mit dem sie es vorziehen würden zu studieren. Eine qualitative Analyse untersucht Perspektiven und Präferenzen der Teilnehmer für bestimmte Vertretungen und Identitäten kultureller Themen in Bezug auf die von Hofstede aufgestellten Dimensionen. Auswirkungen auf die Gestaltung von Bildern für cross‐kulturelle Nutzer werden diskutiert.

The Use of Computers in the Education of Open University Students with Disabilities

Abstract

In 1988 the Open University is implementing a major new policy on the use of computers in its courses; students taking certain courses will be obliged to have access to a microcomputer. This new policy has many far‐reaching consequences, not least for students who are disabled. In the past most computing in Open University courses has been done by students using terminals in local study centres, linked to the University's mainframe computers. Also, a number of students who are disabled have used computers in their studies, principally for word‐processing written work. By interviewing disabled students who have taken such courses, and surveying other disabled students, it has been possible to anticipate to some extent the likely impact of the home‐computing (HC) policy. Results suggest that for many disabled‐ students the HC policy represents an improvement in their opportunities; now they will be able to study courses involving computers entirely at home. However, a number of problems have also been identified. Hopefully, as many of these have been recognised at an early stage, it will be possible to address them before they affect students directly.     

The life and work of Niels Bohr — A brief sketch

The life and work of Niels Bohr are briefly reviewed covering: his family life, background, and education; the importance of his stay in England after PhD, and the crucial contact with Rutherford; the period of the Old Quantum Theory initiated by his work on atomic structure; and his role as mentor to the next generation of physicists through his Institute in Copenhagen. The contacts with Einstein, their debates on quantum mechanics, their deep mutual respect, and their personalities, are described.     

Fascinating organic molecules from nature

Among the traditional five sensory perceptions, colour and smell often go hand in hand, along with taste. Among the objects used for worshipping God, for instance, flowers and incenses occupy prime places. The subject matter of this article is the chemistry of musk and related perfumes derived from natural sources.     

Lipophorin receptor: The insect lipoprotein receptor

The low-density lipoprotein receptor (LDLR), one of the best characterized cell-surface receptors, mediates cholesterol homeostasis and other functions in mammals. The members of the LDLR superfamily are structurally related and characterized by distinct functional domains. Insect lipoprotein receptor is called lipophorin receptor (LpR) and belongs to the LDLR superfamily. Here, we review the structural and functional aspects of lipophorin receptors.     

The sacred lotus

The lotus is very much a part of Indian cultural traditions. Its importance has long been recognized and it has been grown for use as food, medicine and also for cultural and religious activities. Significantly, the longevity of the lotus seed is phenomenal, with viable seeds dated as being 1300 years old. Seed germination of the lotus is very rare in Nature; however, farmers’ knowledge and experience may show how lotus seeds can be germinated.     

Correlation between variables subject to an order restriction,with application to scientometric indices

Variables subject to an order restriction, for instance Y ≤ X, have a bivariate distribution over a non-rectangular joint domain that entails a non-null and potentially large structural relation even if the variables show no association (in the sense that particular ranges of values of X do not co-occur with particular ranges of values of Y). Order restrictions affect a number of scientometric indices (including the h index and its variants) that are routinely subjected to correlational analyses to assess whether they provide redundant information, but these correlations are contaminated by the structural relation. This paper proposes an alternative definition of association between variables subject to an order restriction that eliminates their structural relation and reverts to the conventional definition when applied to variables that are not subject to order restrictions. This alternative definition is illustrated in a number of theoretical cases and it is also applied to empirical data involving scientometric indices subject to an order restriction. A test statistic is also derived which allows testing for the significance of an association between variables subject to an order restriction.     

The Reading Habits of Superior College Students

A structured team approach in learning introductory COBOL programming was empirically assessed with a sample of 215 undergraduate business administration majors. For each assigned program, students in the experimental group read and critiqued team members’ program listings. COBOL proficiency was measured by a final examination testing knowledge of language rules, ability to read a program, and the ability to write a program. Analysis of multiple covariance was used to statistically adjust test scores for age and conditional reasoning scores. For the program writing variable, a significant difference favoring the experimental group was found. The language rules variable showed no significant difference, while the reading variable did not satisfy the required assumptions of the proposed statistical model. However, the experimental group showed higher mean scores for both of these variables. The findings provide empirical support for incorporating team activities into the programming learning process to more effectively develop student proficiency in writing COBOL programs.     

A Study of Sensori-Motor and Conceptual Thinking in Children between the Ages of Nine and Eighteen

In this research, the author addresses whether the application of unidimensional item response models provides valid interpretation of test results when administering items sensitive to multiple latent dimensions. Overall, the present study found that unidimensional models are quite robust to the violation of the unidimensionality assumption due to secondary dimensions from sensitive items. When secondary dimensions are highly correlated with main construct, unidimensional models generally fit and the accuracy of ability estimation is comparable to that of strictly unidimensional tests. In addition, longer tests are more robust to the violation of the essential unidimensionality assumption than shorter ones. The author also shows that unidimensional item response theory models estimate item difficulty parameter better than item discrimination parameter in tests with secondary dimensions.
