Global Regulation Of A Σ54-Dependent Flagellar Gene Family In Caulobacter Crescentus By The Transcriptional Activator Flbd, Jianguo Wu, Andrew K. Benson, Austin Newton Jan 1995

Global Regulation Of A Σ54-Dependent Flagellar Gene Family In Caulobacter Crescentus By The Transcriptional Activator Flbd, Jianguo Wu, Andrew K. Benson, Austin Newton

Faculty Publications in Food Science and Technology

Biosynthesis of the Caulobacter crescentus polar flagellum requires the expression of a large number of flagellar (fla) genes that are organized in a regulatory hierarchy of four classes (I to IV). The timing of fla gene expression in the cell cycle is determined by specialized forms of RNA polymerase and the appearance and/or activation of regulatory proteins. Here we report an investigation of the role of the C. crescentus transcriptional regulatory protein FlbD in the activation of σ54-dependent class III and class IV fla genes of the hierarchy by reconstituting transcription from these promoters in vitro. Our ...


Menu Engineering: A Model Including Labor, Stephen M. Lebruto, William J. Quain, Robert A. Ashley Jan 1995

Menu Engineering: A Model Including Labor, Stephen M. Lebruto, William J. Quain, Robert A. Ashley

Hospitality Review

Menu engineering is a methodology to classify menu items by their contribution margin and popularity. The process discounts the importance of food cost percentage, recognizing that operators deposit cash, not percentages. The authors raise the issue that strict application of the principles of menu engineering may result in an erroneous evaluation of a menu item, and also may be of little use without considering the variable portion of labor. They describe an enhancement to the process by considering labor.


Placement For Profit: Menu Item Arrangement On Customer-Activated Computer Screens, Ken Smith, Susan Gregory, Susan Gould Jan 1995

Placement For Profit: Menu Item Arrangement On Customer-Activated Computer Screens, Ken Smith, Susan Gregory, Susan Gould

Hospitality Review

Can profitable menu items be placed on a computer screen where they will be selected more readily than other items? The author examines whether printed menu theories and techniques can be applied, with the same results, to a computer menu screen
