Richard Johnson, newly appointed president of Century Airlines, knew the company's survival depended on customer service, which in turn depended on motivated employees. So he created the Century Spirit program to build team spirit by encouraging employee participation, individual initiative, and open communication. Among the program's early successes was a newspaper started by a group of flight attendants. The Plane Truth published information about benefits and work conditions as well as feature stories and humorous articles. It quickly became popular not only with flight attendants but also with pilots, machinists, and baggage handlers. As time went on, though, the Plane Truth began to run articles critical of the company. When management cut back workers' hours, the newspaper questioned what sacrifices the executives were making. When technical services released figures showing long turnaround times, the paper questioned the machinists' work ethic. Worried that customers might see the newspaper, Richard Johnson wanted to cancel it. The president of the flight attendants union also wanted to see it go because it was stirring up trouble with the machinists. Joan Raffin, Century's human resources director, was asked to stop the publication. But she hesitated. She knew that employee morale was on the brink, but she didn't know whether the newspaper was venting workers' frustrations and reinforcing team spirit or stirring up old animosities and bringing the whole company down. Was it creating more tension than unity or vice versa? Experts on organizational change, motivation, and management analyze the situation and make recommendations for what Joan Raffin should do.  相似文献

This paper has grown out of a long standing personal concern that the current approaches to design teaching are too narrowly based and that they can distort the very activity that they set out to encourage. A survey of the comments made in Examiner's Reports of pupil's work in public design examinations during 1986 & 1987 provides some insight into the difficulties that pupils experienced in carrying out their design activities.Design activity in schools developed from the beginnings initiated by the curriculum development projects of the late 1960's and early 1970's. These put forward methodical approaches to designing which have become widely used in UK secondary schools and which are now firmly embedded in the publications and project assessment framework of the current national examinations.The present study suggests that, while these methodical approaches clearly work, they imply a logical progression of thought which does not necessarily parallel the pattern of human thinking. It is recognised that pupil's design folios written up at the end of a project can be made to describe a logical, systematic procedure which has more to do with the assessment framework than the actual developments of design ideas during the project. Indeed, teachers and candidates were being actively encouraged to base their work on these structured frameworks:The actual style and quality of the folder presentation is also important. This is particularly so when working to a detailed mark scheme. Certainly it is easier to mark a folder which broadly follows the pattern of the mark scheme than one which is very erratic. Teachers are advised as to the advantages of using the mark scheme as a teaching tool and as a guide for folder presentation. NEA, 1986.Finally, the paper examines some more recent developments in the procedural models of design activity and the way in which professional designers approach their work. These insights provide an indication of the way forward for school design work and its assessment.  相似文献

Often overlooked as an important kitchen design element, properly sized refrigeration and freezing equipment is an important contributor to a kitchen's functionality. In many operations, particularly large-volume units, walk-in refrigerators are the anchors of a good cold-storage system. A walk through three different foodservice operations--a college, a hotel and a hospital--finds walk-ins at work.  相似文献
