Subresultants in multiple roots: an extremal case

We provide explicit formulae for the coefficients of the order-d polynomial subresultant of (x-\alpha)^m and (x-\beta)^n with respect to the set of Bernstein polynomials \{(x-\alpha)^j(x-\beta)^{d-j}, \, 0\le j\le d\}. They are given by hypergeometric expressions arising from determinants of binomial Hankel matrices.Comment: 18 pages, uses elsart.

The design principles for flow experience in educational games

Educational games have to be well designed to incorporate learner engagement, an integral component of educational effectiveness. One foundation of designing educational engagement is flow theory. This article presents a flow framework that describes the building blocks of flow experience that can be used to design appealing and effective educational games for formal and informal learning contexts. The framework provides the principles for good educational game design, based upon associative, cognitive and situative learning theories, including engagement and pedagogic elements with a focus upon feedback and flow principles. Furthermore, the paper clarifies the relation between the flow experience and immersion. We tested the flow framework in the RealGame case study, which revealed that the RealGame business simulation game was well designed and effective at engaging student.We found tht the university student; flow experience in the game was high and the findings indicated that sense of control, clear goals and challenge-skill dimensions of flow scored the highest, but a rewarding experience and feedback dimensions also scored highly by the students. Overall, the results indicate that flow framework is a useful tool in studying game-based learning experiences

FINANCIAL REPORTS AND SHAREHOLDERS’ DECISION MAKING IN NIGERIA: ANY CONNECTEDNESS?

The preeminent objective of this paper is to ascertain the impact of financial statements on shareholders’ investment decision making in Nigeria. We employed the use of well-structured questionnaire to elicit the perception of shareholders regarding the importance of financial statements for investment decision making and also their discernment of the adequacy of the content of financial statements. The two hypotheses formulated in the course of the study, were tested by the use of ANOVA test and the Likelihood Ratio Test, and otherwise referred to as G-test or maximum likelihood statistical significance test. The results of the empirical tests show that Stockholders do possess the requisite technical and professional skills to analyze IFRs financial Statement. And that Stakeholders in financial reporting in Nigeria do rely on the Financial Information disclosed in financial statements for investment decision making. We recommended inter alia that stakeholders should in addition to the accounting figures in the financial statement, compute ratio, trend and common size analysis in order to secure deeper information. Secondly, investors should not be unaware of the possibility of the use of creative accounting techniques by directors, in painting a distorted picture of the state of health of the reporting entities. Additionally, investors should be mindful of the fact that financial statements are historical in nature. Since the past do not always paint a perfect picture of the present or future, investors should in addition to financial statements analysis, investigate the internal and external environment of the reporting entities before arriving at a final investment decision

Microbiological quality of fermented Cassava Flakes (Gari) sold in Yenagoa, Metropolis, Nigeria

The study investigated the microbial quality of gari (viz yellow and white) sold in five markets of Yenagoa metropolis, Nigeria. Three Fifteen samples of each type of gari were obtained from each market. Microbiological examination of the samples was carried using standard microbiological procedure. Results showed that total heterotrophic bacteria, total coliform and total fungi ranged from 3.848 to 4.973 Log cfu/g, 2.659 to 3.793 Log cfu/g and 3.371 to  3.832 Log cfu/g respectively (yellow gari); 4.206 to 5.206 Log cfu/g, 3.242 to 3.803 Log cfu/g, and 3.887 to 4.145 Log cfu/g respectively (white gari). Analysis of variance of Log coliform forming counts showed that there was no significance difference (P>0.05) among the various markets. The microbial density is within acceptable and tolerable level for ready to eat food. The bacterial species tentatively identified in both gari types include Micrococcus, Klebsiella, Proteus, Bacillus and Corynebacterium species, Pseudomonas aeruginosa, Staphylococcus aureus, Enterobacter aerogenes and E. coli. The fungal species are Aspergillus niger, Fusarium, Rhizopus, Mucor and Penicillium species. Some of these microbes found in gari samples are suspected potential pathogens to human health
