    Six undergraduates participated in concurrent-choice experiment with monetary reinforcers. Each subject was exposed to a time-based analog of concurrent variable-interval variable-ratio schedule with equal time interval values. The time-based analog of variable-interval schedule arranged reinforcers throughout the session, and delivered them while the schedule was chosen. The time-based analog of variable-ratio schedule arranged and immediately delivered reinforcers only while the schedule was chosen. In the time-based analog of concurrent variable-interval variable-ratio schedule, matching theory predicts increase in time allocated to the former schedule, whereas maximization theory predicts increase in time allocated to the latter schedule. Four of six subjects developed preference for the time-based variable-ratio analog schedule. No subjects developed preference for the time-based variable-interval analog schedule. The results did not support the argument that human choice behavior is governed by matching processes and maximization is derivative of the processes.

    “Alphanumeric category effect” refers to the finding that letters and digits are identified more efficiently when they were presented among items from the opposite category (a between-category condition, BC) than among items from the same category (a within-category condition, WC). Two experiments in this article revealed that the category effect occurred when BC and WC condition were divided into blocks but did not occur when these were not divided. This means that the category effect is due to strategy of the subjects rather than to category relation between target and distractor.

    In an earlier paper in this journal (Holden 1997a) I argued that television commercials utilize color to deliver essential meaning. This argument was based upon a sample of over 10,000 commercials from America and Japan culled over the past five years. Relative to black and white the analysis revealed, among other things, that this color set functioned as signifier, metaphor and myth in often similar ways across societal boundaries. In short, contrary to the popular view articulated in semiotics and cultural studies this particular sign set evinced a great deal of “unisemy”. This paper takes up where the last left off, critically assessing the implications of the unisemy finding. It asks “to what degree does color exist as indicia of a homogenous or homogenizing world?” In short, can color shed any light on the question of globalization–a key concern in discussions of modern and post-modern (i.e. “information”) society. To answer this question I compare the uses, conventions and meanings of particular colors in comparative context. I conclude that while evidence of homogenization can be found, there are also large pockets of distinctive use and meaning-conferral. At least relative to America and Japan, color in advertising illuminates large zones of practical and ideational uniqueness in the focal societies.

    This paper examines the possibility of incorporating models of free migration and regional-urban framework into a CIGE (computable intertemporal general equilibrium) model, and presents “an operational model of national formation”, in which we can simulate and depict the configuration of regional-urban land use affected by the forthcoming liberalized macroeconomic circumstances i.e., the step-by-step reduction of tariff on imported goods. It is impossible for us to evaluate the recent Japanese macroeconomic direction until we devise the model introducing the intertemporal system as a kind of import substitution policy such that a target year of its balanced trade account is considered.

    A simple macro econometric model is constructed to evaluate the road transport policies in Japan. The model is unique in that the economic repercussion of traffic volume is incorporated, and a generalized cost function of road transportation is introduced.

    In this paper, the ability of a human operator in tracking the desired trajectory with high precision using an iterative learning technique is studied. Experiments are designed to provide the best perception of data and fine control to the human operator. Results of the experiments show the ability of the human operator to perform the tracking tasks very precisely. The convergence of the human control input to the desired control input is observed to be fast. Furthermore the control strategy of the human operator is analyzed in this paper.

    LOTOS, one of the formal description techniques, can strictly and unambiguously describe the requirement specifications of distributed systems such as protocols and communication systems. But it is difficult for beginners to learn and understand LOTOS. Thus, for LOTOS instruction support, we have already proposed an algorithm which can detect learner’s errors contained in the learner’s answer for some problems described in LOTOS. This algorithm is applied to non-recursive LOTOS processes. However, non-recursive processes cannot represent processes that execute events infinitely. In this paper, we propose a new algorithm which can support equivalence decision and error detection in recursive processes. We also present a software support system which aids this new algorithm.
