A violation of procedure invariance in preference measurement is that the predominant or prominent attribute looms larger in choice than in a matching task. In Experiment 1, this so-called prominence effect was demonstrated for choices between pairs of options, choices to accept single options, and preference ratings of single options. That is, in all these response modes the prominent attribute loomed larger than in matching. The results were replicated in Experiment 2, in which subjects chose between or rated their preference (...) for pairs of options which were matched to be equally attractive either in the same session or 1 week earlier. On the basis of these and previous results, it is argued that the prominence effect is a reliable phenomenon. However, none of several cognitive explanations which have been offered appears to be completely viable. (shrink)

Intertemporal choice is the study of how people make choices about what and how much to do at various points in time, when choices at one time influence the possibilities available at other points in time. These choices are influenced by the relative value people assign to two or more payoffs at different points in time. Most choices require decision-makers to trade off costs and benefits at different points in time. These decisions may be about savings, work effort, education, nutrition, (...) exercise, health care and so forth. Since early in the twentieth century, economists have analyzed intertemporal decisions using the discounted utility model, which assumes that people evaluate the pleasures and pains resulting from a decision in much the same way that financial markets evaluate losses and gains, exponentially 'discounting' the value of outcomes according to how delayed they are in time. Discounted utility has been used to describe how people actually make intertemporal choices and it has been used as a tool for public policy. Policy decisions about how much to spend on research and development, health and education all depend on the discount rate used to analyze the decision. (shrink)

When we talk of African philosophy as a different philosophical tradition we do not wish to suggest that it studies different range of realities from those that concern the other philosophical traditions. What we demonstrate is the difference that arises in approach or method naturally informed by the resident logic. Thus in African philosophy we study ultimate reality of which being is at the center. What being and even nothingness mean for us is not the same with what they mean (...) in other traditions. Unity: we sometimes say that being is one single whole without wishing to say that this view is monistic. In this light we hold that being is complete with both physical and spiritual aspects. Duality: we also share the view on the duality in nature without insisting that this is strict and permanent. Duality for Africans is essentially a point of inferential departure not a terminal point. The dual arrangement of things in nature is to necessarily lead to a tripartite conception. Triadic conception: this is the terminal point of all inferences in African thought. Yes, there is duality in nature but they exist as fragments and contraries i.e. incomplete in themselves but capable of coming together to form a whole. Obtaining this fusion of contrary fragments represents an inference from duality to triadic conception of reality. What this African conception is all about is not that being is tripartite or dual but that the coming together of two aspects of being is necessary for the formation of being. (shrink)

The art of the theatre is a collaborative enterprise. It involves the creative efforts of different artists: director, stage manager, set, lighting, properties, costume, make-up and sound designers. These artists work together for the realization of a theatrical production. They work within a production concept which is the guiding principle upon which a production is based. However, as the theatre is audio-visual and immediate, it is the duty of these artists to ensure that every aspect of the production is perfectly (...) deployed for the audience’s understanding of the play. Of all the artists of the theatre, the scenic designer’s work is the most eloquent visual expressive element in the theatre because he is the artist responsible for interpreting the play/drama in concrete visual terms through the creation of an aesthetically pleasing and functional background. This essay interrogates the use of scenic design in countering terrorism in the Unizik performance of Emma Dandaura’s Venom for Venom. The study finds that through adequate use of the elements and principles of design that the scenic artist was able to counter the spate of terrorism as depicted in the play through his set design. It submits that terror in a theatrical performance can be ameliorated through subtle use of design for the audience’s better understanding of the message of the play. (shrink)

Dictionary making is the preoccupation of a lexicographer (dictionary compiler) and the art of making it (dictionary) is called lexicography. Dictionary can either be in printing or electronic form. It is no doubt a vital tool for language learning and usage. The importance of a dictionary in learning and usage of a language cannot be neglected because its role in learning generally which includes among others: word meaning, word usage, pronunciation, spelling, origin and parts of speech are fundamental in communication. (...) The research adopts secondary sources of data collection. The neglect of the use of dictionary for study by our students is no doubt the cause of poor language performance, low performance in examination and poor individual vocabulary acquisition. This work will therefore be limited to the features of a dictionary that will serve as a guide to dictionary users. (shrink)

Two experiments with undergraduates as subjects tested explanations of how a prior temporary income change influences choices between buying and deferred buying. In Experiment 1 predictions from the behavioral life-cycle theory (Shefrin & Thaler, 1988), the renewable resources model (Linville & Fischer, 1991) and the loss-sensitivity principle (Garling & Romanus, 1997) were contrasted. The results are inconsistent with the latter two explanations since the framing of buying as positive (buying a new model of a product) or negative (replacing a (...) broken product) did not interact with the income change. Congruent with the behavioral life-cycle theory, willingness to buy was greater when subjects received a temporary income increase than when they received a temporary income decrease although total assets were equal. Further support for the behavioral life-cycle theory is obtained in Experiment 2 where four income-change conditions and durable and nondurable goods are compared. (shrink)

The paper, Some Indigenous Solutions to African Environmental Problems: An Appraisal, is written to examine the relevance of African Environmental Philosophies to addressing African environmental problems. African environmental problems include: water pollution, air pollution, land pollution, climate change, flood and many more. Researchers have shown that these problems are caused by phenomena like coal mining, nuclear waste, deforestation, overfishing, wars, etc. It is a known fact that attempts have been made over the years to resolve these problems, with pockets of (...) successes, yet more needs to be done. Nigeria’s Niger Delta Development Commission, Kenya’s Bio-safty Act 2009, The National Environment Policy of Ghana, Oil Pipeline Act 2004, Nuclear Safety and Radiation Protection Act 2004 are a good example of such attempts with pockets of successes and challenges. This work uses the methods of rational speculation and critical analysis to examine aboriginal approaches to resolving African environmental challenges as recorded in Mark Omorovie Ikeke’s Philosophical Consciences, Caroline N. Mbonu’s Ecospiritualism, Thaddeus Metz’s Model Relationalism, and Chimakonam Jonathan Okeke’s Ohanifism. This work charged African environmental policymakers, Lecturers, and Students with the responsibility to understand and apply the theoretical foundation for sustainable living as recorded in the above philosophies. This is the time when Africans must use indigenous African methods and principles to proffer solutions to African environmental problems. (shrink)
