Fuzzy logic has become an important tool for a number of different applications ranging from the control of engineering systems to artificial intelligence. In this concise introduction, the author presents a succinct guide to the basic ideas of fuzzy logic, fuzzy sets, fuzzy relations, and fuzzy reasoning, and shows how they may be applied. The book culminates in a chapter which describes fuzzy logic control: the design of intelligent control systems using fuzzy if-then rules which make use of human knowledge (...) and experience to behave in a manner similar to a human controller. Throughout, the level of mathematical knowledge required is kept basic and the concepts are illustrated with numerous diagrams to aid in comprehension. As a result, all those curious to know more about fuzzy concepts and their real-world application will find this a good place to start. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 37.4 (2003) 32-41 [Access article in PDF] Does Art Education Dream of Disneyland? [Figures] Introduction What image can we present when challenged to illustrate art education in the form of a scheme? The word "illustration" literally means to build understanding through an explanatory diagram. In art education or anything [End Page 32] else, the use of a visual image to understand a certain system (...) can be interpreted as a question of human sensitivity and recognition. Translating minute nuances or peculiarities of information into a vibrant image is, however, a confusing and difficult exercise. In this essay, I attempt to portray those elements crucial to the teaching and learning process of art education using Disneyland as a structural as well as a functional metaphor. The Happiest Place on Earth? Disneyland is depicted as "a dream world" and "the happiest place on earth." As described in various incisive essays, Disneyland is a symbol of modern American culture, an ultimate form of the consumer society or the hegemony of entertainment. 1 To start with, the structural elements of this epitome of Walt Disney's vision are outlined.Walt Disney created Main Street USA (the World Bazaar) to make all visitors feel as if they are the leading character in a Disney film, walking through the main street of life. He attempted to remove the ugliness of everyday life from his dream space by eradicating the back streets of the real world. The design of the buildings along Main Street originates from Walt Disney's hometown. The sense of distance within the Disney complex is enhanced by using a smaller scale for the upper stories of buildings and a progressively narrowing street.Sleeping Beauty's Castle (or Cinderella Castle at Tokyo Disneyland) lies beyond Main Street and is modeled on Neuschwanstein Castle in Fussen,South Bayern, Germany. The road leading to the castle ascends slightly which amplifies the anticipation factor for visitors. Sleeping Beauty's Castle is the centerpiece of Disneyland and functions as the hub to guide visitors to various lands. Several attractive spaces radiate from this hub, forming a total of six areas.On the extension line from the Entrance via Sleeping Beauty's Castle lies Fantasyland where Walt Disney has reproduced the world of animation based on European legends and fables. Toontown lies beyond Fantasyland. This is a world of familiar characters, such as Mickey, Minnie, and Goofy. Traveling clockwise, Tomorrowland is next where all kinds of imaginary worlds await visitors. Adventureland, on the opposite side of Main Street, offers worlds of different cultures and spaces for adventure. Beyond Adventureland lies Westernland, designed to invite visitors to return to the Wild West.It is possible to form a hypothesis that there are three axes connecting the six lands. Those axes run through Sleeping Beauty's Castle that acts as the hub and two opposing areas on the same axis with the Castle being the point of symmetry.The first axis could be the axis of "reality." If Main Street is considered to be the "crawling approachway" from the everyday sphere to dreamland,Fantasyland, offering playful space of extraordinary imagination, is set [End Page 33] against the ordinary space for everyday life. The second axis is the axis of "relationship" which connects individual persons to society. Toontown presents a world of fraternity and is a place where people bonded by kinship or friendship can trust each other and feel at ease. Frontierland, located on the opposite side of this axis creates a solitary space where people leave family and friends for the adventure of traveling to unknown lands. The third and final axis is that of "time" from the past to the future. Tomorrowland is a future world based on fantasy and imagination where prophecies becomereality. On the opposite side of this axis lies Westernland embodying the history and traditions of the American past.It is possible to regard each area of Disneyland, structured by these different worlds, as a metaphor to reflect the basic content and structure of art education in the context of the general curriculum.

Legislative scholars have debated what factors (e.g. divided government) account for the number of important laws a legislative body passes per year. This paper presents a monopoly model for explaining legislative production. It assumes that a legislature adjusts its law production so as to maximize its utility. The model predicts that socio-economic and political changes increase the marginal benefit of law production, whereas low negotiation costs and ample legislative resources decrease the marginal cost of law production. The model is tested (...) in two ways. The first approach compares the legislatures of 42 developed and developing countries. The second analyzes Japanese lawmaking from 1949 to 1990, using an appropriate method for event count time series data. Both empirical investigations support the model's predictions for legislative production. (shrink)

This article reconsiders how to judge judicial independence by using the Japanese judicature, one of the allegedly-most dependent judiciary branches. In their influential work, Ramseyer and Rasmusen argue that judges who once belonged to a leftist group take longer to reach a under the long-term conservative rule of Japan. Their method does not, however, deal appropriately with the possibility of judges not reaching this position because the judge dies, retires early, or is still at the early stage of her career. (...) Ramseyer and Rasmusen also mistakenly assume that all judges will eventually obtain this position. This article develops a survival analysis model of judicial careers and attempts to solve the problems of censoring, left truncation, and split population. We also offer a way to utilize a matching procedure to estimate average treatment effects on censored time-to-event as well as event occurrence. We re-analyze a corrected version of Ramseyer and Rasmusen's data using their and our methods. One of the most important findings is that, contrary to what Ramseyer and Rasmusen argue, leftist judges are not discriminated against in terms of the timing of promotion. (shrink)

We consider a spatial bargaining model where players collectively choose a facility location on a two-dimensional rectilinear distance space through bargaining using the unanimity rule. We show that as players become infinitely patient, their stationary subgame perfect equilibrium utilities converge to the utilities that satisfy the lexicographic maximin utility criterion introduced by Sen.
