Image Quality: Perception and Quantification
Instructor: Eric K. Zeise, NexPress Solutions, Inc.

A meaningful description of image quality requires an accurate linkage between the measurement of an attribute and its perceived quality. Measurement without a linkage to perception can lead to meaningless specsmanship. Perception without objective measurement can degenerate to opinion. In this course, we examine the characteristics and limitations of human visual perception and the models of perception used to describe the appearance of objects. From this perspective, we identify important attributes of image quality and investigate measurement techniques used to quantify these attributes. We examine the scope, utility and limitations of standards that permit comparison of non-impact printing device image quality. We will work through short examples of psychometric scaling methods that create the required relationship between instrumental measurement and perceived quality, allowing a meaningful, quantitative measurement of perceived image quality.

Benefits:
This course will enable you to:

Utilize psychometric scaling methods to provide meaningful, quantitative measurement of perceived image quality

Business in Japan
Instructor: Robert J. Nash, Consultant, Hafren Associates

Since Japan continues to be an active center for research, development and marketing for non-impact marking technologies, travel to Japan has become a routine event for many Western engineers, technologists and business professionals involved in such technologies. However, for many Westerners, repeated travel to Japan does not eliminate the strong feeling of being a foreigner in a distinctly non-Western environment. Though survival in such a foreign environment can be eased thanks to written instructions provided by thoughtful Japanese hosts, by willingness for Japanese counterparts to use English as a common language, etc., subtle cross-cultural issues still remain as causes for unease in the Western mind. Unfortunately, such issues tend to increase as a result of repeated visits — gradually, an observant Western visitor will begin to comprehend some of the unwritten rules that govern life in Japan, and in retrospect will appreciate just how many social gaffes can made during initial, casual visits. While such gaffes may be viewed as minor embarrassments by some Westerners, it is important to realize, from a working relationship viewpoint, that Japanese hosts will evaluate Western visitors on the basis of such gaffes — it is human nature to use internal benchmarks to form opinions, and since the Japanese rules of behavior are significantly non-Western, there are great opportunities for misunderstandings and erroneous judgments. From problems with footwear, with chopsticks, with forms of verbal address, with overall decorum, etc., the possibilities for transgressions seem endless, even if the cures are often trivial. Accordingly, in my tutorial I hope that I can provide an inside Western perspective on some of the more baffling aspects of interactions in a Japanese environment, and offer some pointers for behavior that will delight and impress Japanese hosts and colleagues. The course will focus on general cultural and interpersonal topics. Advanced business-oriented topics such as Western vs. Japanese negotiation strategies, Japanese financial systems, Japanese labor rules, etc., will not be covered.

Benefits:
This course will enable you to:

Learn about Japanese life through the experiences of a resident foreigner living daily in a Japanese environment
Handle the logistics of everyday life in Japan — travel by trains and taxis, dining in restaurants, etc.
Use and comprehend key, short Japanese phrases — greetings, questions, expressions of thanks, etc.
Develop a clear and understandable pronunciation of common Japanese words and phrases
Develop an understanding of the historical and cultural framework to life in Japan
Appreciate the importance of introductions, of gift-giving, etc.
Identify and interpret the “Japanese Unwritten Rules of Behavior” — body language, “code words”, expected responses, etc.
Recognize the need for harmony, for a quiet self-effacing demeanor, for patience, for apologies, etc.
Understand the style of business interactions — consensus, teamwork, attention to detail, devotion to Company, etc.

Intended Audience: This course will be of interest to all “foreigners” who travel to Japan on business, especially those who still feel confused and uncomfortable even after repeated short-term visits. Japanese nationals might also appreciate the foreigner’s view of their homeland presented in the tutorial — such a perspective might help explain some of the puzzling behavior typically shown by visiting foreigners.

Robert J. Nash was a xerographic research technologist at the Xerox Corporation from 1970 until 2001. After fifteen years of short technology-interchange visits to Japan, he finally relocated to Japan in 1988 for a long-term expatriate assignment. For almost three years he spent his days as the lone Xerox Resident at Fuji Xerox, Takematsu, while his wife steadily expanded her circle of Japanese friends through activities such as quilting and informal English Conversation classes. They lived in a hybrid Japanese/Western house in a totally Japanese residential area away from Tokyo, and since all of their friends were Japanese they became well-established as the
