Organization of Multi-Agent Systems: An Overview
In complex, open, and heterogeneous environments, agents must be able to
reorganize towards the most appropriate organizations to adapt unpredictable
environment changes within Multi-Agent Systems (MAS). Types of reorganization
can be seen from two different levels. The individual agents level
(micro-level) in which an agent changes its behaviors and interactions with
other agents to adapt its local environment. And the organizational level
(macro-level) in which the whole system changes it structure by adding or
removing agents. This chapter is dedicated to overview different aspects of
what is called MAS Organization including its motivations, paradigms, models,
and techniques adopted for statically or dynamically organizing agents in MAS.Comment: 12 page
Affordances of spreadsheets in mathematical investigation: Potentialities for learning
This article, is concerned with the ways learning is shaped when mathematics problems are investigated in spreadsheet environments. It considers how the opportunities and constraints the digital media affords influenced the decisions the students made, and the direction of their enquiry pathway. How might the leraning trajectory unfold, and the learning process and mathematical understanding emerge? Will the spreadsheet, as the pedagogical medium, evoke learning in a distinctive manner? The article reports on an aspect of an ongoing study involving students as they engage mathematical investigative tasks through digital media, the spreadsheet in particular. In considers the affordances of this learning environment for primary-aged students
Analysis and intuition in strategic decision making. The case of California
Many management scholars believe that the process used to make strategic decisions affects the quality of
those decisions. However several authors have observed a lack of research on the strategic decision making
process. Empirical tests of factors that have been hypothesized to affect the way strategic decisions
are made notably are absent. (Fredrickson, 1985) This paper reports the results of a study that attempts
to assess the effects of decision making circumstances focusing mainly on the approaches applied and the
managerial skills and capabilities the decision makers built on during concrete strategic decision making
procedures. The study was conducted in California between September 2005 and June 2006 and it was
sponsored by a Fulbright Research Scholarship Grant
From tools to theories: The emergence of modern financial economics
It is shown that early research in modern financial economics had substantially been driven by the application of the research strategy of economics and the use of newly developed mathematical methods. For this purpose the professionalization of business education as a consequence of changes in the U.S. economy after Word War II is presented. The emergence of professional Journals in financial economics, similar to the academic culture including the trend of applying abstract mathematical reasoning and during the war developed methods like linear programming are highlighted. Also the meaning of Milton Friedman's 1953 essay The Methodology of Positive Economics for the dominance of abstract and prediction driven research in modern financial economics gets discussed. Finally, the emergence of Harry Markowitz's paper Portfolio Selection (1952) is used to substantiate the hypothesis. --history of finance,portfolio theory,business schools,modern financial economics,modelling,theories of modern financial economics,risk management,positivism,professionalization,methodology of finance
Classtalk: A Classroom Communication System for Active Learning
This pdf file is an article describing the advantages of using Classtalk technology in the classroom to enhance classroom communication. Classtalk technology cab facilitate the presentation of questions for small group work, collec the student answers and then display histograms showing how the class answered. This new communication technology can help instructors create a more interactive, student centered classroom, especially when teaching large courses. The article describes Classtalk as a very useful tool not only for engaging students in active learning, but also for enhancing the overall communication within the classroom. This article is a selection from the electronic Journal for Computing in Higher Education. Educational levels: Graduate or professional
