What's in a Name? Price Variation in Sport Facility Naming Rights

There are two generally accepted ways of plotting the aggregate demand (AD) and aggregate supply (AS) curves in the goods market. One puts the price level on the vertical axis (the P - y approach); the other plots the real interest rate on the vertical axis (the r - y approach). This paper develops the theoretical connections between these two approaches that permit one to tell a coherent dynamic story with the AD-AS model and also explores the conditions under which one approach or the other yields greater insight into the working of the model.Advertising; Sports

Jets in strongly-coupled N = 4 super Yang-Mills theory

We study jets of massless particles in N=4 super Yang-Mills using the AdS/CFT correspondence both at zero and finite temperature. We set up an initial state corresponding to a highly energetic quark/anti-quark pair and follow its time evolution into two jets. At finite temperature the jets stop after traveling a finite distance, whereas at zero temperature they travel and spread forever. We map out the corresponding baryon number charge density and identify the generic late time behavior of the jets as well as features that depend crucially on the initial conditions.Comment: 21 pages, 12 figures. Added discussion regarding string profiles in more than one spatial dimension. Refs adde

Traceability in Food Systems: An Economic Analysis of LGMA and the 2006 Spinach Outbreak

This case study presents an in-depth review of network structures and costs associated with the implementation of traceability systems in California leafy green production, distribution, and retailing. The 2006 spinach outbreak is used to assess the economic impact of trace back/forward response time of the LGMA system, an example of a tightly coupled, linear supply network. Results suggest that the benefits of traceability systems may far outweigh the costs and that costs vary significantly by technology used and by grower size. Implications are derived for cost-effectiveness of rapid response, targeted trace back/forward systems in other types of supply networks.traceability, produce, supply networks, cost-effectiveness, Food Consumption/Nutrition/Food Safety, Production Economics, Q18, I18, L51,

Microsoft Enterprise Consortium How To’s for the Classroom

Practical workshop that includes presentations and “hands on” use of examples and exercises utilizing the Microsoft Enterprise Consortium hosted at the University of Arkansas Sam M. Walton College of Business Enterprise Systems. Industry partners of the Enterprise Systems program at the Sam M. Walton College of Business have donated computing systems and multiple, large-scale datasets for instructional use – Sam’s Club (6 tables and over 55 million rows of POS transactions for 18 stores), Dillard’s Department Stores (5 tables with a transactions table of 120 million rows), Tyson Foods, and Wal-Mart RFID data sets. This workshop provides faculty “How To’s” that can be incorporated into a wide variety of courses that include topics on databases, data warehousing, business intelligence and decision making. The Microsoft Enterprise Consortium includes the full SQL Server 2008 Management Studio and Business Intelligence Development Studio. Further, this Consortium includes access to the large datasets referenced above plus a number of datasets corresponding to database and data mining texts

Two wheeled lunar dumptruck

The design of a two wheel bulk material transport vehicle is described in detail. The design consists of a modified cylindrical bowl, two independently controlled direct drive motors, and two deformable wheels. The bowl has a carrying capacity of 2.8 m (100 ft) and is constructed of aluminum. The low speed, high HP motors are directly connected to the wheels, thus yielding only two moving parts. The wheels, specifically designed for lunar applications, utilize the chevron tread pattern for optimum traction. The vehicle is maneuvered by varying the relative angular velocities of the wheels. The bulk material being transported is unloaded by utilizing the motors to oscillate the bowl back and forth to a height at which dumping is achieved. The analytical models were tested using a scaled prototype of the lunar transport vehicle. The experimental data correlated well with theoretical predictions. Thus, the design established provides a feasible alternative for the handling of bulk material on the moon

Introduction to financial management for foreign military staff officers

The nature of our research was to determine the content, scope and structure for a course in basic financial management which would be used to introduce foreign military officers to the field of financial management. The Naval Education and Training Security Assistance Field Activity (NETSAFA) indicated there was a need for a generic, introductory financial management course because of the numerous inquiries from foreign governments concerning financial management subject matter. Foreign officials requested that their staff officers, which have varying degrees of familiarity with the financial arena, be schooled in the basics of financial management. Research determined that the course should be approximately two weeks in length in order to adequately cover the following subject areas: accounting, budgeting, management fundamentals, auditing, management information systems (MIS), and total quality management (TQM). In addition to formulating the content, scope and structure of the course, a draft student and instructors' guide were developed and are included in Appendices A and B.http://archive.org/details/introductiontofi00bryaLieutenant Commander, United States NavyApproved for public release; distribution is unlimited
